(c) The Corporation shall designate, in respect of the Bonds, a person to act as "Bond Registrar," provided that the Bond Registrar shall be either the Trustee or a person which would meet the requirements for qualification as a Trustee imposed by Section 11.13 hereof. The Corporation hereby appoints the Trustee its Bond Registrar in respect of the Bonds. Any other person undertaking to act as Bond Registrar shall first execute a written agreement, in form satisfactory to the Trustee, to perform the duties of a Bond Registrar under this Indenture, which agreement shall be filed with the Trustee. DMWEST#16808481 v7 26 The Bond Registrar shall act as registrar and transfer agent. The Corporation shall cause to be kept at an office of the Bond Registrar a register(herein sometimes referred to as the "Bond Register") in which, subject to such reasonable regulations as it or the Bond Registrar may prescribe, the Corporation shall provide for the registration of the Bonds and for the registration of transfers of the Bonds. The Corporation shall cause the Bond Registrar to designate, by a written notification to the Trustee, a specific office location (which may be changed from time to time, upon similar notification) at which the Bond Register is kept. The principal operations center of the Trustee shall be deemed to be such office in respect of any series of Bonds for which the Trustee is acting as Bond Registrar. The Bond Registrar shall, in any case where it is not also the Trustee, forthwith following each Regular Record Date and at any other time as reasonably requested by the Trustee, certify and furnish to the Trustee, and to the Paying Agent as the Trustee shall specify, the names, addresses, and holdings of Bondholders and any other relevant information reflected in the Bond Register, and the Trustee and any such Paying Agent shall for all purposes be fully entitled to rely upon the information so furnished to it and shall have no liability or responsibility in connection with the preparation thereof. Section 2.04. Registration,Transfer and Exchange Upon their execution and authentication and prior to their delivery, the Bonds shall be registered for the purpose of payment of principal and interest by the Bond Registrar. To the extent that typewritten Bonds, rather than printed Bonds, are to be delivered, such modifications to the form of Bond as may be necessary or desirable in such case are hereby authorized and approved. There shall be no substantive change to the terms and conditions set forth in the form of Bond, except as otherwise authorized by this Indenture or any amendment thereto. As provided in Section 2.03 hereof, the Corporation shall cause a Bond Register for the Bonds to be kept at the designated office of the Bond Registrar. Upon surrender for transfer of any Bond at such office, the Corporation shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees, one or more new fully registered Bonds of authorized denomination for the aggregate principal amount which the registered owner is entitled to receive. At the option of the Owner, the Bonds may be exchanged for other Bonds of any authorized denomination, of a like aggregate principal amount, upon surrender of the Bonds to be exchanged at any such office or agency. Whenever any Bonds are so surrendered for exchange, the Corporation shall execute, and the Trustee shall authenticate and deliver, the Bonds which the Bondholder making the exchange is entitled to receive. All Bonds presented for transfer or exchange, redemption or payment (if so required by the Corporation, the Bond Registrar or the Trustee), shall be accompanied by a written instrument or instruments of transfer or authorization for exchange, in form and with guaranty of signature satisfactory to the Trustee, duly executed by the Owner or by his attorney duly authorized in writing. DMWEST#16808481 v7 27 In any circumstances concerning the payment or registration of the Bonds not covered specifically by this Indenture, the Trustee shall act in accordance with federal and state banking laws and its normal procedures in such matters. A reasonable service charge shall be made to the presenter for any exchange or transfer of Bonds. The Corporation may require payment of a sum sufficient to cover any tax or other governmental charge that may also be imposed in relation thereto. Neither the Corporation nor any Bond Registrar on behalf of the Corporation shall be required (i) to issue, transfer or exchange any Bond during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of Bonds selected for redemption and ending at the close of business on the day of such mailing, or (ii) to transfer or exchange any Bond so selected for redemption in whole or in part. New Bonds delivered upon any transfer or exchange shall be valid obligations of the Corporation, evidencing the same debt as the Bonds surrendered, shall be secured by this Indenture and entitled to all of the security and benefits hereof to the same extent as the Bonds surrendered. Section 2.05. Execution The Bonds shall be executed by the manual or facsimile signature of the President or any Vice President of the Corporation, and the corporate seal of the Corporation or facsimile thereof shall be affixed, imprinted, lithographed or reproduced thereon and shall be attested by the manual or facsimile signature of the Secretary of the Corporation. Bonds executed as above provided may be issued and shall, upon request of the Corporation, be authenticated by the Trustee, notwithstanding that any officer of the Corporation signing such Bonds shall have ceased to hold office at the time of issuance or authentication or shall not have held office at the date of the Bond. Section 2.06. Authentication No Bond shall be valid for any purpose until the certificate of authentication shall have been duly executed by the Trustee, and such authentication shall be conclusive proof that such Bond has been duly authenticated and delivered under this Indenture and that the owner thereof is entitled to the benefit of the trust hereby created. Section 2.07. Payment of Principal and Interest; Interest Rights Preserved The principal, interest, and redemption price of any Series 2011A Bond or Series 2017 Bonds shall be payable as provided in the specimen and forms of such Bonds (as applicable) attached hereto as Exhibit A. To the extent principal of any Bond is not paid when due, such principal shall remain outstanding until paid. Subject to the foregoing provisions of this Section 2.07, each Bond delivered under this Indenture upon transfer of or exchange for or in lieu of any other Bond shall carry the rights to interest accrued and unpaid, and to accrue,which were carried by such other Bond. DMWEST#16808481 v7 28 Section 2.08. Persons Deemed Owners The Corporation, the Trustee, any Paying Agent and the Bond Registrar may deem and treat the person in whose name any Bond is registered as the absolute owner thereof (whether or not such Bond shall be overdue and notwithstanding any notation of ownership or other writing thereon made by anyone other than the Corporation, the Trustee, the Paying Agent or the Bond Registrar) for the purpose of receiving payment of or on account of the principal of (and premium, if any, on), and(subject to Section 2.07 hereof) interest on, such Bond, and for all other purposes, and neither the Corporation, the Trustee, the Paying Agent nor the Bond Registrar shall be affected by any notice to the contrary. All such payments so made to any such registered owner, or upon his order, shall be valid and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Bond. Section 2.09. Mutilated,Destroyed,Lost or Stolen Bonds If any Bond shall become mutilated, the Corporation shall execute, and the Trustee shall thereupon authenticate and deliver, a new Bond of like tenor and denomination in exchange and substitution for the Bond so mutilated, but only upon surrender to the Trustee of such mutilated Bond for cancellation, subject to the Trustee and the Corporation being furnished such reasonable indemnity as either of them may require therefor. If any Bond shall be reported lost, stolen or destroyed, evidence as to the ownership and the loss, theft or destruction thereof shall be submitted to the Trustee; and if such evidence shall be satisfactory to it and such indemnity satisfactory to the Trustee and the Corporation shall be given, the Corporation shall execute, and thereupon the Trustee shall authenticate and deliver, a new Bond of like tenor and denomination as the original Bond, but carrying such additional marking as will enable the Trustee to identify such Bond as a replacement Bond. The cost of providing any substitute Bond under the provisions of this Section shall be borne by the Bondholder for whose benefit such substitute Bond is provided. If any such mutilated, lost, stolen or destroyed Bond shall have matured or be about to mature, the Trustee shall pay to the owner the principal amount of such Bond upon the maturity thereof and the compliance with the aforesaid conditions by such owner, without the issuance of a substitute Bond therefor. Every substituted Bond issued pursuant to this Section 2.09 shall constitute an additional contractual obligation of the Corporation, whether or not the Bond alleged to have been destroyed, lost or stolen shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Bonds duly issued hereunder. All Bonds shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Bonds, and shall preclude any and all other rights or remedies,notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or investment or other securities without their surrender. DMWEST#16808481 v7 29 Section 2.10. Temporary Bonds Pending preparation of definitive Bonds, or by agreement with the purchasers of all Bonds, the Corporation may issue and, upon its request, the Trustee shall authenticate in lieu of definitive Bonds one or more temporary printed or typewritten Bonds in authorized denominations of substantially the tenor recited above. Upon request of the Corporation, the Trustee shall authenticate definitive Bonds in exchange for and upon surrender of an equal principal amount of temporary Bonds. Until so exchanged,temporary Bonds shall have the same rights, remedies and security hereunder as definitive Bonds. Section 2.11. Cancellation and Destruction of Surrendered Bonds Bonds surrendered for payment, redemption, transfer or exchange, and Bonds purchased from any moneys held by the Trustee hereunder or surrendered to the Trustee by the Corporation, shall be cancelled in accordance with the customary practice of the Trustee and applicable retention laws. Section 2.12. Supplemental Act Provisions By execution of this Indenture, the Corporation hereby elects to have all provisions of the Supplemental Act apply to the issuance of the Bonds; provided, however, that such election shall not operate to modify or limit the rights conferred on the Corporation or the members of the Board by any other provisions of State law. Pursuant to Section 11-57-210 of the Supplemental Act, each Bond shall recite that it is issued under the authority of the resolution of the Board and the Supplemental Act and that it is the intention of the Corporation that such recital shall be conclusive evidence of the validity and the regularity of the issuance of the Bonds after their delivery for value. Pursuant to Section 11-57-208 of the Supplemental Act, the Project Revenues, as received by or otherwise credited to the Corporation, shall immediately be subject to the lien of such pledge without any physical delivery, filing or further act. The lien of such pledge and the obligation to perform the contractual provisions made in this Indenture shall have priority over any or all other obligations and liabilities of the Corporation. The lien of such pledge shall be valid,binding and enforceable as against all persons having claims of any kind of tort, contract or otherwise against the Corporation irrespective of whether such persons have notice of such lien.

Failure to give such notice by mailing to any Owner, or any defect therein, shall not affect the validity of any proceeding for the redemption of other Bonds as to which no such failure or defect exists. All Bonds so called for redemption will cease to bear interest after the specified redemption date, provided funds for their redemption are on deposit at the place of payment at that time. If at the time of mailing of notice of an optional redemption there shall not have been deposited with the Trustee moneys sufficient to redeem all the Bonds called for redemption, such notice may state that it is conditional, that is, subject to the deposit of the redemption moneys with the Trustee on the scheduled redemption date, and such notice shall be of no effect unless such moneys are so deposited; provided, however, that if such conditional notice of redemption is given with respect to the redemption of the Series 2011A Bonds, then such notice shall be of no effect unless such moneys are deposited with the Trustee not later than the opening of business five Business Days prior to the date fixed for redemption. Section 9.04.

Section 9.06. Bond Redemption Fund for Refunding Issues Whenever the Corporation issues Bonds hereunder for refunding purposes, the Corporation may, by supplemental indenture authorizing the Bonds, direct the Trustee to establish a separate bond redemption fund and to deposit therein the proceeds of the refunding Bonds.

DMWEST#16808481 v7 69 Any Event of Default described in this Section 10.01(d) or (e) may be waived by the Trustee if the Corporation is proceeding with due diligence to cure such default and the Corporation is not otherwise in default under(a), (b) or(c) of this Section. Section 10.02. Acceleration and Annulment Thereof Subject to Section 10.06, if any Event of Default occurs, the Trustee shall, subject to the rights of the County set forth in this Section 10.02, by notice in writing to the Corporation declare the principal of all Bonds then Outstanding to be immediately due and payable; and upon such declaration the said principal, together with premium, if any, and interest accrued thereon, shall become due and payable immediately at the place of payment provided therein, anything in the Indenture or in said Bonds to the contrary notwithstanding. If, after the principal of said Bonds has been so declared to be due and payable, all arrears of interest upon the Bonds (and interest on overdue installments of interest at the rate borne by the Bonds) are paid or caused to be paid by the Corporation, and the Corporation also performs or causes to be performed all other things in respect to which it may have been in default hereunder and pays or causes to be paid the reasonable charges of the Trustee and the Bondholders, including reasonable attorney's fees, then, and in every such case, the Majority Interest, by notice to the Corporation and to the Trustee, may annul such declaration and its consequences and such annulment shall be binding upon the Trustee and upon all Owners of Bonds issued hereunder; but no such annulment shall extend to or affect any subsequent default or impair any right or remedy consequent thereon. Notwithstanding the foregoing, upon the occurrence of an Event of Default, the Trustee shall within five (5) days of such occurrence, provide notice to the County, and the County shall have the option, to cure such Event of Default within ninety (90) days after receipt of notice. Amounts advanced by the County as a result of the exercise of this option to cure monetary defaults hereunder and reasonable, direct expenses of the County advanced to cure non-monetary defaults hereunder shall be deemed to be Indebtedness of the Corporation to the County, entitled to payment from the Revenue Fund pursuant to Section 4.05 hereof. Nothing herein shall be construed to create any obligation of the County to cure any Event of Default. Section 10.03. Legal Proceedings by Trustee If any Event of Default has occurred and is continuing, the Trustee in its discretion may, and upon the written request of the Majority Interest and receipt of indemnity to its satisfaction, shall, in its own name, or in combination with the Corporation: A.

Discontinuance of Proceedings by Trustee If any proceeding taken by the Trustee on account of any Event of Default is discontinued or is determined adversely to the Trustee, the Corporation, the Trustee and the Bondholders shall be restored to their former positions and rights hereunder as though no such proceeding had been taken,but subject to the limitations of any such adverse determination. Section 10.05. Bondholders May Direct Proceedings The Majority Interest shall have the right, by an instrument or concurrent instruments in writing delivered to the Trustee, to direct the method and place of conducting all remedial proceedings to be taken by the Trustee hereunder provided that such directions shall not be otherwise than in accordance with the law or the provisions of this Indenture. Without limitation of the foregoing, any such remedial proceeding may include forbearance or non-action on the part of the Trustee, the acceptance by the Trustee, as beneficiary under the Deed of Trust, of a deed in lieu of foreclosure, the sale of the property covered by the Deed of Trust free of the lien thereof for an amount less than the amounts due with respect to the Bonds and the waiver of claims or the granting of a covenant not to sue. Before taking any action hereunder requested by Bondholders, the Trustee may require that it be furnished an indemnity bond or other indemnity satisfactory to it for the reimbursement of all expenses to which it may be put and to protect it against all liability, except liability which results from the negligence or willful misconduct of the Trustee,by reason of any action so taken or omitted to be taken by the Trustee. Section 10.06. Limitations on Actions by Bondholders No Bondholders shall have any right to pursue any remedy hereunder unless: (a) the Trustee shall have been given written notice of an Event of Default, (b) the Owners of at least 25% in principal amount of the Bonds Outstanding respecting which there has been an Event of Default shall have requested the Trustee, in writing, to exercise the powers hereinabove granted or to pursue such remedy in its or their name or names, (c) the Trustee shall have been offered indemnity satisfactory to it against costs, expenses and liabilities, such satisfaction in all respects subject to Section 10.13 hereof, and (d) the Trustee shall have failed to comply with such request within a reasonable time.

Trustee May Enforce Rights Without Possession of Bonds All rights under the Indenture and the Bonds may be enforced by the Trustee without the possession of any Bonds or the production thereof at the trial or other proceedings relative thereto, and any proceedings instituted by the Trustee shall be brought in its name for the ratable benefit of the Owners of the Bonds. Section 10.08. Delays and Omissions Not to Impair Rights No delay or omission in respect of exercising any right or power accruing upon any Event of Default shall impair such right or power or be a waiver of such Event of Default and every remedy given by this Article may be exercised from time to time and as often as may be deemed expedient. Section 10.09. Application of Moneys in Event of Default Upon the occurrence of any Event of Default, the Trustee shall not disburse any moneys from any Fund or account established hereunder without the written consent of the Majority Interest provided that the Trustee may expend moneys for Operation and Maintenance Expenses pursuant to the Operating Budget unless directed to the contrary by the Majority Interest. Subject to the provision that in no event will amounts deposited in (i) the Debt Service Reserve Fund be applied other than to pay principal of or interest on the Bonds while any such Bonds are Outstanding, (ii) the PFC Account be applied other than to pay principal on the PFC Eligible Bonds while any such Bonds are Outstanding, and (iii) the PFC Interest Subaccount be applied other than to pay interest on the PFC Interest Eligible Bonds while any such Bonds are Outstanding, all moneys received by the Trustee pursuant to any right given or action taken under the provisions of this Article X or the Deed of Trust and any other moneys held as part of the Trust Estate shall be deposited in the Bond Fund, after payment of the cost and expenses of the proceedings resulting in the collection of such moneys and of the expenses, liabilities, and advances incurred, or made by the Trustee, including reasonable attorney's fees, costs and expenses, and all other current outstanding fees and expenses of the Trustee, such moneys shall be applied in the order set forth below: (a) Unless the principal on all Bonds shall have become or been declared due and payable, all such moneys shall be applied: First: To the payment of all installments of interest then due on the Bonds with interest on such overdue interest at the rate per annum borne by such Bonds and, if the amount available shall not be sufficient to pay in full any particular installment together with such interest, then to the ratable payment of the amounts due on such installment; Second: To the payment of the unpaid principal of any of the Bonds (other than Bonds called for redemption for the payment of which moneys are held pursuant to the provisions of the Indenture), with interest on such Bonds at the rate per annum borne by such Bonds from the respective dates upon which they become due and, if the amounts available shall not be sufficient to pay in full the Bonds due on any particular date, together with such interest, then to the ratable payment of the amounts due on such date; DMWEST#16808481 v7 72 Third: To the payment to the County of all Indebtedness to the County; and Fourth: To the payment of Subordinate Bonds. (b) If the principal of all the Bonds shall have become or been declared due and payable, all such moneys shall be applied(i) first, to the payment of the principal, premium, if any, and interest then due and unpaid upon the Bonds with interest on such overdue amounts at the rate of interest borne thereby, without preference or priority as between principal,premium or interest on such Bonds,ratably according to the amounts due respectively for principal, premium and interest to the Persons entitled thereto, (ii) second, to payments of Indebtedness due the County arising hereunder, and (iii)third to the payment of any Subordinate Bonds. (c) If the principal on all Bonds shall have been declared due and payable, and if such declaration shall thereafter have been rescinded under this Article then, subject to paragraph (b) of this Section in the event that the principal of all the Bonds shall later become or be declared due and payable, the moneys shall be applied in accordance with paragraph(a) of this Section. Whenever moneys are to be applied pursuant to this Section, the Trustee shall fix the date (which shall be the earliest practical date, in the sole discretion of the Trustee, for which the requisite notice can be given)upon which such application is to be made and upon such date interest on the amounts of principal to be paid on such dates shall cease to accrue. The Trustee shall give such notice as it may deem appropriate of the deposit with it of any such moneys and of the fixing of any such date. Section 10.10. Trustee and Bondholders Entitled to All Remedies; Remedies Not Exclusive It is the purpose of this Article to provide to the Trustee and the Bondholders all rights and remedies as may be lawfully granted under State law; but should any remedy herein granted be held unlawful, the Trustee and the Bondholders shall nevertheless be entitled to every remedy permitted under State law.

Appointment of Co-Trustee It is the purpose of this Indenture that there shall be no violation of any law of any jurisdiction (including particularly the laws of the State of Colorado) denying or restricting the right of banking corporations or associations to transact business as Trustee in such jurisdiction. It is recognized that in case of litigation under this Indenture, and in particular in case of the enforcement of any such document in default, or in case the Trustee deems that by reason of any present or future law of any jurisdiction it may not exercise any of the powers,rights or remedies herein granted to the Trustee or hold title to the properties, in trust, as herein granted, or take any other action which may be desirable or necessary in connection therewith, it may be necessary that the Trustee appoint an additional individual or institution as a separate or Co-Trustee. The following provisions of this Section are adopted to these ends. The Trustee may appoint an additional individual or institution as a separate or Co-Trustee, in which event such and every remedy, power,right, claim, demand, cause of action, indemnity, estate, title, interest and lien expressed or intended by this Indenture to be exercised by or vested in or conveyed to the Trustee with respect thereto shall be exercisable by and vest in such separate or Co-Trustee but only to the extent necessary to enable such separate or Co- Trustee to exercise such powers, rights and remedies, and every covenant and obligation necessary to the exercise thereof by such separate or Co-Trustee shall run to and be enforceable by either of them. Should any deed, conveyance or instrument in writing from the Corporation be required by the separate or Co-Trustee so appointed by the Trustee for more fully and certainly vesting in and confirming to him or it such properties, rights, powers, trusts, duties and obligations, any and all such deeds, conveyances and instruments in writing shall, on request, be executed, acknowledged and delivered by the Corporation. In case any separate or Co-Trustee,or a successor to either, shall die, become incapable of acting, resign or be removed, all the estates, properties, rights, powers, trusts, duties and obligations of such separate or Co-Trustee, so far as DMWEST#16808481 v7 78 permitted by law, shall vest in and be exercisable by the Trustee until the appointment of a new Trustee or successor to such separate or Co-Trustee.

Recording and Filing The Trustee covenants that it will cause all financing statements related to this Indenture and the Deed of Trust (except, in each case, the initial financing statements) and all supplements thereto, and such other security agreements, financing statements and all supplements thereto and other instruments as may be required or recommended from time to time by Bond Counsel to be kept, to be recorded and filed in such manner and in such places as may from time to time be required by law in order to preserve and protect fully the security of the Bondholders and the rights of the Trustee hereunder. The Trustee, at the direction of the Corporation or Bond Counsel, shall take or cause to be taken any and all other action deemed necessary by the Corporation or Bond Counsel to perfect the security interest created by this Indenture or the Deed of Trust, all at the expense of the Corporation. Without limiting the foregoing,until the Deed of Trust Termination Date the Trustee shall file continuation statements with respect to each UCC financing statement relating to the Deed of Trust filed at the time of the issuance of each series Bonds. In addition, unless the Trustee shall have been notified in writing by the Corporation or Bond Counsel that any such initial filing or description of collateral contained therein was or has become defective or is no longer adequate, due to place of filing, collateral description, or any other appropriate reason, to protect fully the security of the Bondholders and the rights of the Trustee thereunder, the Trustee shall be fully protected in (a) relying on such initial filing and description in filing any financing or continuation statements or modifications thereto pursuant to this section, and (b) filing any continuation statements in the same filing offices as the initial filings were made. The Corporation shall be responsible for the customary fees charged by the Trustee for the preparation and filing of continuation statements and for the reasonable costs incurred by the Trustee in the preparation and filing of all continuation statements hereunder. Section 11.19.Privileges and Immunities of Paying Agent and Registrar The Paying Agents and the Registrar shall, in the exercise of their duties hereunder, be afforded the same rights, discretions, privileges and immunities as the Trustee in the exercise of such duties.

If it shall have reasonable grounds for believing that repayment of advanced funds or adequate indemnity against such risk or liability is reasonably assured to it, the Trustee may, in its sole discretion, expend its own funds in the performance of any of its duties hereunder. The Trustee shall not be required to give any bond or surety in respect to the execution of its trusts and powers hereunder or otherwise. ARTICLE XII.

All capitalized terms used but not defined herein shall have the meanings assigned to such terms in the Indenture or the Preliminary Official Statement (as defined below), unless the context clearly indicates otherwise. The Underwriter agrees to purchase the 2017A Bonds at a price of $ (the "2017A Purchase Price"), being the par amount of the 2017A Bonds of$ , [plus] net original issue [premium] of$ , less the Underwriter's discount on the 2017A Bonds of $ .

The Bonds shall be issued and secured under the Indenture and shall contain the terms set forth in Exhibit A hereto and the Indenture. The Corporation acknowledges and agrees that: (i)the primary role of the Underwriter, as underwriter, is to purchase securities, for resale to investors, in an arm's-length commercial transaction between the Corporation and the Underwriter in which the Underwriter is acting solely as principal and is not acting as a municipal advisor, financial advisor or fiduciary to the Corporation and that the Underwriter has financial and other interests that differ from those of the Corporation; (ii) the Underwriter is not acting as municipal advisor, financial advisor, or fiduciary to the Corporation and has not assumed any advisory or fiduciary responsibility to the Corporation with respect to the transaction contemplated hereby and the discussions, undertakings and procedures leading thereto (irrespective of whether the Underwriter has provided other services or is currently providing other services to the Corporation on other matters); (iii) the only obligations the Underwriter has to the Corporation with respect to the transaction contemplated hereby expressly are set forth in this Purchase Contract; and (iv) the Corporation has consulted its own financial and/or municipal, legal, accounting, tax and other advisors, as applicable, to the extent it deems appropriate. The Underwriter agrees to make a bona fide public offering of all of the Bonds at prices not to exceed the public offering prices set forth on the inside cover page of the Official Statement and may subsequently change such offering prices without any requirement of prior notice. The Underwriter may offer and sell Bonds to certain dealers (including dealers depositing Bonds into investment trusts) and others at prices lower than the public offering prices stated on the inside cover of the Official Statement. The Underwriter agrees to assist the Corporation in establishing the issue price of the Bonds and shall execute and deliver to the Corporation at Closing an "issue price" or similar certificate, together with the supporting pricing wires or equivalent communications, substantially in the form attached hereto as Appendix C, with such modifications as may be appropriate or necessary, in the reasonable judgment of the Underwriter, the Corporation and Ballard Spahr LLP, Bond Counsel to the Corporation("Bond Counsel"), to accurately reflect, as applicable, the sales price or prices or the initial offering price or prices to the public of the Bonds. [IF 10% IS SOLD: The Corporation will treat the first price at which 10% of each maturity of the Bonds (the "10% test") is sold to the public as the issue price of that maturity (if different interest rates apply within a maturity, each separate CUSIP number within that maturity will be subject to the 10% test). At or promptly after the execution of this Purchase Agreement, the Underwriter shall report to the Corporation the price or prices at which it has sold to the public each maturity of Bonds. If at that time the 10% test has not been satisfied as to any maturity of the Bonds, the Underwriter agrees to promptly report to the Corporation the prices at which it sells the unsold Bonds of that maturity to the public. That reporting obligation shall continue, whether or not the Closing has occurred,until the 10%test has been satisfied as to the Bonds of that maturity or until all Bonds of that maturity have been sold to the public. The Underwriter confirms that any selling group agreement and any retail distribution agreement relating to the initial sale of the Bonds to the public, together with the related pricing wires, contains or will contain language obligating each dealer who is a member of the selling group and each broker-dealer that is a party to such retail distribution agreement, as applicable, to (A) report the prices at which it sells to the public the unsold Bonds of each maturity allotted 2 to it until it is notified by the Underwriter that either the 10% test has been satisfied as to the Bonds of that maturity or all Bonds of that maturity have been sold to the public and(B) comply with the hold-the-offering-price rule, if applicable, in each case if and for so long as directed by the Underwriter. The Corporation acknowledges that, in making the representation set forth in this subsection, the Underwriter will rely on (i) in the event a selling group has been created in connection with the initial sale of the Bonds to the public, the agreement of each dealer who is a member of the selling group to comply with the hold-the-offering-price rule, if applicable, as set forth in a selling group agreement and the related pricing wires, and (ii) in the event that a retail distribution agreement was employed in connection with the initial sale of the Bonds to the public, the agreement of each broker-dealer that is a party to such agreement to comply with the hold-the-offering-price rule, if applicable, as set forth in the retail distribution agreement and the related pricing wires. The Corporation further acknowledges that the Underwriter shall not be liable for the failure of any dealer who is a member of a selling group, or of any broker-dealer that is a party to a retail distribution agreement, to comply with its corresponding agreement regarding the hold-the-offering-price rule as applicable to the Bonds.] [IF HOLD THE OFFERING PRICE IS USED: The Underwriter confirms that it has offered the Bonds to the public on or before the date of this Purchase Agreement at the offering price or prices (the "initial offering price"), or at the corresponding yield or yields, set forth in Appendix C attached hereto, except as otherwise set forth therein. Appendix C also sets forth, as of the date of this Purchase Contract, the maturities, if any, of the Bonds for which the 10%test has not been satisfied and for which the Corporation and the Underwriter, agree that the restrictions set forth in the next sentence shall apply, which will allow the Corporation to treat the initial offering price to the public of each such maturity as of the sale date as the issue price of that maturity(the"hold-the-offering-price rule"). So long as the hold-the-offering-price rule remains applicable to any maturity of the Bonds, the Underwriter will neither offer nor sell unsold Bonds of that maturity to any person at a price that is higher than the initial offering price to the public during the period starting on the sale date and ending on the earlier of the following: (i) the close of the fifth(5th)business day after the sale date; or (ii)the date on which the Underwriter has sold at least 10% of that maturity of the Bonds to the public at a price that is no higher than the initial offering price to the public. The Underwriter shall promptly advise the Corporation when it has sold 10% of that maturity of the Bonds to the public at a price that is no higher than the initial offering price to the public, if that occurs prior to the close of the fifth(5th)business day after the sale date.] The Underwriter acknowledges that sales of any Bonds to any person that is a related party to the Underwriter shall not constitute sales to the public for purposes of this section. Further, for purposes of this section: (i) "public"means any person other than an underwriter or a related party, (ii) "underwriter" means (A) any person that agrees pursuant to a written contract with the City (or with the lead underwriter to form an underwriting syndicate) to participate in the initial sale of the Bonds to the public and(B) any person that agrees pursuant to 3 a written contract directly or indirectly with a person described in clause (A) to participate in the initial sale of the Bonds to the public (including a member of a selling group or a party to a retail distribution agreement participating in the initial sale of the Bonds to the public), (iii) a purchaser of any of the Bonds is a"related party"to an underwriter if the underwriter and the purchaser are subject, directly or indirectly, to (i) at least 50% common ownership of the voting power or the total value of their stock, if both entities are corporations (including direct ownership by one corporation of another), (ii) more than 50% common ownership of their capital interests or profits interests, if both entities are partnerships (including direct ownership by one partnership of another), or (iii) more than 50% common ownership of the value of the outstanding stock of the corporation or the capital interests or profit interests of the partnership, as applicable, if one entity is a corporation and the other entity is a partnership (including direct ownership of the applicable stock or interests by one entity of the other), and (iv) "sale date" means the date of execution of this Purchase Contract by all parties.

See `APPENDIX D—FORM OF THE INDENTURE"for definitions of certain words and terms used herein which are not otherwise defined herein. INTRODUCTION This introduction is not a summary of this Official Statement. It is only a summary description of and guide to, and is qualified by, more complete and detailed information contained in the entire Official Statement, including the cover page and appendices hereto and the documents summarized or described herein. A full review should be made of the entire Official Statement. The offering of Series 2017 Bonds to potential investors is made only by means of the entire Official Statement. General The purpose of this Official Statement, which includes the cover page, table of contents, and appendices, is to provide certain information concerning the sale and delivery by Eagle County Air Terminal Corporation (the "Corporation") of its Airport Terminal Project Revenue Refunding Bonds, Series 2017A (the "Series 2017A Bonds") and its Airport Terminal Project Revenue Improvement Bonds, Series 2017B (the "Series 2017B Bonds" and collectively with the Series 2017A Bonds, the"Series 2017 Bonds"). The Corporation The Corporation is a Colorado nonprofit corporation, organized in April 1996 under the Nonprofit Corporation Law of the State of Colorado, with the powers to, among other things, promote and assist in carrying out the provision of airport services by Eagle County, Colorado (the"County"). See"THE CORPORATION AND THE COUNTY." *Preliminary,subject to change. DMWEST#16594819 v6 Purpose of the Series 2017 Bonds The Series 2017A Bonds are being issued to: (a) currently refund all of the Corporation's Airport Terminal Project Revenue Improvement Bonds, Series 2006B, outstanding in the aggregate principal amount of$1,565,000 (the "Series 2006B Bonds"), (b) fund a portion of the Debt Service Reserve Fund for the Series 2017 Bonds, and (c) finance a portion of the costs of issuance, as described herein. The Series 2017B Bonds are being issued to: (a) finance the costs of the acquisition and construction of real and personal property, buildings and improvements, including all other work in connection therewith, relating to the Terminal Expansion Project, (b) fund a portion of the Debt Service Reserve Fund for the Series 2017 Bonds, and (c) finance a portion of the costs of issuance, as described herein. See"SOURCES AND USES OF FUNDS." Series 2017 Bonds The Series 2017 Bonds will be issued under an Amended and Restated Trust Indenture dated as of 1, 2017 (the "Indenture"), by and between the Corporation and UMB Bank, National Association, as trustee (the "Trustee"). The Series 2017 Bonds are also being issued in accordance with Revenue Ruling 63-20, 1963 C.B. 24 and its successor provisions, Revenue Procedure 82-26 and Sections 103 and 141-150 of the Internal Revenue Code of 1986, as amended, and are to be issued on behalf of the County by the Corporation. The Series 2017 Bonds are secured by a pledge and lien on Project Revenues (as defined herein) on a parity with the pledge thereof and lien thereon of the Series 2011A Bonds (as defined herein) and any Additional Bonds issued on parity with the Series 2017 Bonds and the Series 2011A Bonds pursuant to the terms of the Indenture. For purposes of this Official Statement, "Bonds" shall mean the Series 2017 Bonds, the Series 2011A Bonds and any Additional Bonds, and the term "Additional Bonds" shall mean any additional bonds issued under the Indenture which are secured by and payable from any part of the Net Revenues (as defined herein), but does not include any Special Facilities Bonds or Subordinate Bonds (both as defined in Appendix D). See"APPENDIX D—FORM OF THE INDENTURE." Project Revenues include, but are not limited to: (a) all revenues earned or received by the Corporation from the use or operation of the Project, including, without limitation, amounts payable by each of American Airlines, Inc. ("American"), United Air Lines, Inc. ("United"), and Delta Air Lines, Inc., ("Delta")pursuant to the Terminal Building Leases (as defined in"- Terminal Building Leases" below) with the Corporation and rental amounts, if any, paid by the County to the Corporation pursuant to a Parking Facilities Sublease, the De-Icing Facility Sublease and the Road Improvements Lease (each as defined herein); (b) with respect to PFC Eligible Bonds (as defined herein), Passenger Facility Charges (as defined below) collected with respect to the Project; (c) Net Loss Proceeds from insurance or condemnation awards; and (d) interest or profits from the investment of certain funds under the Indenture. The County's obligations to make lease payments under the Parking Facilities Sublease, De-Icing Facility Sublease and Road Improvements Lease are subject to annual appropriation by the Board of County Commissioners of the County (the "County Board") and are further subject to other limitations. See "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS," "CERTAIN INVESTMENT CONSIDERATIONS," and "AIRPORT AGREEMENTS." DMWEST#16594819 v6 2 The Indenture defines "PFC Eligible Bonds" as the Series 2011A Bonds, the Series 2017A Bonds and any other series of Bonds issued for projects approved by the Federal Aviation Administration (the "FAA") for funding with the PFC Revenue and which the Corporation, by resolution of the Board of Directors, designated to be PFC Eligible Bonds. For purposes of this Official Statement, "Passenger Facility Charges" or "PFCs" means charges authorized by the FAA to be imposed by the County on enplaning passengers at the Airport, pursuant to the authority granted by the Aviation Safety and Capacity Expansion Act of 1990 (P.L. 101-508)and 14 CFR Part 158, as each amended from time to time (collectively, the "PFC Act"). "PFC Revenue" is defined in the Indenture to mean (i)with respect to the Series 2011A Bonds and the Series 2017A Bonds, revenue derived from passenger facility charges imposed and used for the Project under authority from the FAA pursuant to the PFC Act(net of amounts that collecting air carriers are entitled to retain for collecting, handling and remitting such Passenger Facility Charge revenues), together with any interest earnings thereon, and any PFC Backstop Payments and (ii) with respect to any other series of PFC Eligible Bonds, that portion of revenue derived from passenger facility charges imposed and used for the Project under authority from the FAA pursuant to the PFC Rule that the Corporation,by a supplemental indenture or a resolution of the Board of Directors, designates to be pledged to the PFC Eligible Bonds, together with any interest earnings thereon, and any PFC Backstop Payments. Pursuant to the Project Agreements (defined herein), the County has agreed to collect the PFC Revenue on behalf of the Corporation and covenanted to take any action or avoid taking any action as is necessary to maintain the existing FAA approvals of the use of the revenue from PFCs generated at the Airport for the Project. See "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS—PFC Revenue" and "THE PROJECT—The Project Agreements." PFC Backstop Payments are amounts that are payable by the Signatory Airlines under the Terminal Building Leases, up to an annual maximum of$450,000, in the event the PFC Revenue is not sufficient to pay that portion of the annual debt service on the PFC Eligible Bonds that is eligible to be paid with PFCs (i.e. principal on the Series 2011A Bonds and principal and interest on the Series 2017A Bonds). See "AIRPORT AGREEMENTS—Terminal Building Leases—PFC Backstop Payments." The County does not anticipate applying to the FAA to approve the imposition and use of PFCs to finance the Terminal Expansion Project. Accordingly, PFC Revenue (including the PFC Backstop Payments) will not be pledged to pay the Series 2017B Bonds the proceeds of which will be used to finance the Terminal Expansion Project. The County may at any time apply to the FAA for the authority to collect and use PFCs for any other Airport related projects which are eligible to be financed with PFCs (such as, for example, runway improvements), but which do not constitute part of the Project. Any PFCs which may be approved by the FAA to be collected and used to finance eligible Airport-related projects which do not constitute part of the Project are not pledged to pay the Bonds. Until the Deed of Trust Termination Date (as defined below), the Series 2017 Bonds will also be secured by a pledge of the Corporation's: (i) leasehold interest in the Project Site (as defined herein) leased under the Ground Leases(as defined herein) and(ii) fee simple interest on the Road Improvements Site (as defined below), in each case, pursuant to an Amended and Restated Deed of Trust, Security Agreement and Financing Statement to be dated on or prior to the date of issuance of the Series 2017 Bonds (the "Deed of Trust") from the Corporation for the benefit of the Trustee. The Indenture generally defines the "Deed of Trust Termination Date" DMWEST#16594819 v6 3 as the date on which the Deed of Trust is fully released and discharged in accordance with the terms of the Indenture, which will be no earlier than the date on which the Series 2011A Bonds are paid in full (either upon final maturity, prior redemption, or otherwise) and are no longer Outstanding pursuant to the terms of the Indenture. The Series 2011A Bonds mature on May 1, 2027, but are subject to optional redemption on any date on or after May 1, 2021. See "Project" below and "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS— Deed of Trust." The Indenture imposes certain restrictions on the actions of the Corporation for the benefit of all owners of the Series 2017 Bonds including, among other things, restrictions on liens on the Project (except for Permitted Encumbrances), restrictions on the incurrence of additional indebtedness and provisions governing the maintenance and management of the Project. In the Project Agreements, described below, the County has covenanted to accept, and the Corporation has covenanted to transfer to the County, title to the Project after all principal and interest coming due on the Bonds has been paid or provision for payment therefor has been made. See"THE PROJECT—The Project Agreements." THE SERIES 2017 BONDS SHALL NOT BE A DEBT OR FINANCIAL OBLIGATION OF THE COUNTY, THE STATE OF COLORADO (THE "STATE") OR ANY POLITICAL SUBDIVISION THEREOF WITHIN THE MEANING OF ANY PROVISION OR LIMITATION OF THE CONSTITUTION OR STATUTES OF THE STATE, AND SHALL NEVER CONSTITUTE NOR GIVE RISE TO A PECUNIARY LIABILITY OF THE COUNTY, THE STATE OR ANY POLITICAL SUBDIVISION THEREOF OR A CHARGE AGAINST THEIR GENERAL CREDIT OR TAXING POWERS. THE CORPORATION HAS NO TAXING POWER. Outstanding Parity Bonds The Corporation previously issued $7,250,000 in aggregate principal amount of its Airport Terminal Project Revenue Refunding Bonds, Series 2011A (the "Series 2011A Bonds"), currently outstanding in the aggregate principal amount of$5,135,000. The Series 2011A Bonds are secured by the Trust Estate on parity with the Series 2017 Bonds, subject to certain limitations set forth in the Indenture and except that the PFC Revenue are not pledged to pay the Series 2017B Bonds. See "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS" and "OUTSTANDING OBLIGATIONS AND DEBT SERVICE SCHEDULE." The Corporation may issue Additional Bonds at any time upon compliance with certain requirements of the Indenture. See "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS—Additional Bonds." Project Since 1996, the Corporation has issued bonds in order to finance costs incurred in connection with the acquisition, construction and improvement of Eagle County Regional Airport Terminal Building (the "Terminal Building") and related parking and other improvements (collectively, the "Terminal Building Project") located at the Eagle County Regional Airport (the "Airport"). The real property on which the Terminal Building Project is located (the "Terminal Building Site") is owned by the County and is located within the DMWEST#16594819 v6 4 boundaries of the Airport. The Terminal Building Site has been leased by the County to the Corporation pursuant to a Second Restated Ground Lease effective June 1, 1996,as amended and supplemented (the "Terminal Building Ground Lease"). The Terminal Building Project is operated by the Corporation pursuant to a Project Agreement dated as of June 1, 1996, as amended and supplemented(the"Terminal Building Project Agreement")between the County and the Corporation. See"THE PROJECT—The Project Agreements." Proceeds of the Series 2017B Bonds will be used to finance a portion of the costs relating to the redesign, renovation and expansion of the eastern portion of the existing Terminal Building, as well as the creation of temporary facilities to accommodate concessionaires and other Airport services during such expansion (the "Terminal Expansion Project"). The Terminal Expansion Project would increase the current square footage of the Terminal Building from approximately 91,000 square feet to approximately 141,000 square feet and the expanded eastern portion of the Terminal Building is expected to contain approximately 6 gates, passenger holding rooms, restrooms, support services, security space and concessionaire space. The Corporation entered into a design-build contract (the "DB Contract") with Hensel Phelps Construction Co. as the design-builder of the Terminal Expansion Project (the "Design- Builder"), and retained Menendez Architects pc as the consulting engineer for the Terminal Expansion Project. See"THE PROJECT—Terminal Expansion Project." The DB Contract provides for a guaranteed maximum price of $29,145,837 ("GMP"). The Corporation currently estimates that the Terminal Expansion Project will cost approximately $33,000,000, including the GMP, costs to be paid directly by the Corporation and a contingency amount. Costs of the Terminal Expansion Project not paid with proceeds of the Series 2017B Bonds are expected to be paid from amounts on deposit in the Capital Fund (other than the Minimum Capital Fund Balance). As of August 15, 2017, $6,667,317 was on deposit in the Capital Fund, including the Minimum Capital Fund Balance of $346,000. See "THE PROJECT—The Design-Build Contract for the Terminal Expansion Project" and "APPENDIX D—FORM OF THE INDENTURE—Capital Fund." Proceeds of the Series 2017A Bonds will be used to currently refund the Series 2006B Bonds that were issued to finance the costs of a de-icing facility located within the boundaries of the Airport, certain road improvements to serve the Airport and certain improvements to the Terminal Building. The County and the Corporation entered into a Ground Lease dated as of June 1, 2006, as amended (the "De-Icing Facility Ground Lease" and together with the Terminal Building Ground Lease, the "Ground Leases"), pursuant to which the County leased to the Corporation the real property on which the de-icing facility is located (the "De-Icing Facility Site" and collectively with the Terminal Building Site, the "Project Site") to the Corporation. The De-Icing Facility Site and the improvements constructed thereon were subleased by the Corporation to the County pursuant to the De-Icing Facility Sublease dated as of June 1, 2006, as supplemented (the "De-Icing Facility Sublease"), and are operated by the County. In addition, the Corporation used a portion of the Series 2006B Bonds to acquire approximately 2.0-acre site (the "Road Improvement Site")which was used in connection with the realignment and other improvements of the Airport access roads. The Corporation leased the Road Improvement Site to the County under the Road Improvements Lease dated April 30, 2007, as supplemented (the "Road Improvements Lease"). Pursuant to the Deed of Trust, until the Deed of Trust Termination Date, the Corporation granted its right and title in and to the Road DMWEST#16594819 v6 5 Improvement Site for the benefit of the Trustee as additional security for the Series 2011A Bonds and the Series 2017 Bonds. In addition, revenues of the Corporation from the De-Icing Facility Sublease and the Road Improvements Lease are pledged to pay the Series 2011A Bonds and the Series 2017 Bonds, as more particularly described under"AIRPORT AGREEMENTS- De-Icing Facility Sublease"and"—Road Improvements Lease." In addition,the Corporation and the County entered into a 2006 Project Agreement,dated as of June 1, 2006, as supplemented (the "De-Icing Facility/Road Improvements Project Agreement" and collectively with the Terminal Building Project Agreement, the "Project Agreements") between the County and the Corporation, which grants certain rights to the County with respect to the improvements financed with the Series 2006B Bonds. See "THE PROJECT—Project Agreements." The projects financed with the proceeds of the Series 2006B Bonds are referred to herein as the "2006 Project" and together with the Terminal Building Project and the Terminal Expansion Project are collectively referred to herein as the "Project." See "THE PROJECT" for further information on the Project and"THE AIRPORT" for further information on the Airport. Terminal Building Leases The Corporation has entered into leases, on substantially identical terms, with American, United, and Delta for the use and lease of space in the Terminal Building (collectively, the "Terminal Building Leases"). Such airlines and any other airline that enters into a lease of space in the Terminal Building Project are referred to herein collectively as the "Signatory Airlines" and individually as the "Signatory Airline." The Terminal Building Leases provide for rental payments as well as PFC Backstop Payments in the event that PFCs expected to be collected at the Airport are insufficient to pay that portion of the annual debt service on the PFC Eligible Bonds that is eligible to be paid with the PFC Revenue (i.e. principal on the Series 2011A Bonds and principal and interest on the Series 2017A Bonds). In such event, the Total Rent Amount due from the Signatory Airlines may be increased (proportionately based on enplanements)to include an amount (the"PFC Backstop Payment") equal to "the deficiency in collected PFCs necessary for payment of that portion of the total annual debt service due on the Bonds that would have been eligible for PFC funding under the Airport's PFC application approved by the FAA"; provided, however, that the PFC Backstop Payment collectively paid by the Signatory Airlines may not exceed $450,000 annually. The Terminal Building Leases generally define "Bonds" as debt of the Corporation issued to finance projects for the construction, expansion, improvement or preservation of the Terminal Building and related facilities and services. Because the Series 2017B Bonds are not PFC Eligible Bonds, they are not secured by the PFC Backstop Payments. Under the current Terminal Building Leases, at the end of each Fiscal Year the Corporation is required to refund to the Signatory Airlines fifty percent (50%) of any net Concession Revenues (as defined in "AIRPORT AGREEMENTS—Terminal Building Leases"), subject to a yearly maximum. The current Terminal Building Leases with the Signatory Airlines expire on December 31, 2018, unless either the Corporation or a Signatory Airline exercises its right to terminate DMWEST#16594819 v6 6 sooner. Any Signatory Airline that is not in default under its Terminal Building Lease may terminate its Terminal Building Lease by notifying the Corporation in writing during the five business days preceding April 1 or September 1 of each year, and if the Corporation is in default, at any time upon 30 days' prior written notice. Prior to the expiration of the current Terminal Building Leases on December 31, 2018, the Corporation intends to negotiate extensions or enter into new leases with the Signatory Airlines. The Report of the Airport Consultant (both as defined herein) assumes that for purposes of financial projections contained therein, the Signatory Airlines will extend their Terminal Building Leases through the end of the projection period with agreement provisions and rental amount requirements that are substantially similar to the current Terminal Building Leases. See "Report of the Airport Consultant" below and "AIRPORT AGREEMENTS—Terminal Building Leases" for a more detailed discussion of the Terminal Building Leases and "CERTAIN INVESTMENT CONSIDERATIONS—Terminal Building Leases." The Corporation is not aware of any current defaults under the Terminal Building Leases or that any Signatory Airline plans to terminate its Terminal Building Lease prior to the expiration of its current term.

See "APPENDIX D—FORM OF THE INDENTURE" for a further description of such funds and accounts. Project Revenues include (a) all revenues, income, receipts, proceeds and moneys actually received by the Corporation in any period from the Terminal Building Leases, the rental car concession and lease agreements and any other Terminal Agreements, including the Parking Facilities Sublease, the De-Icing Facility Lease and the Road Improvements Lease or otherwise (other than Ancillary Income and proceeds of borrowing and interest earned thereon if and to the extent such proceeds and interest are required to be excluded by the terms of the borrowing), if any, from rates, fees, tolls, rentals and charges or any combination thereof for the services or privileges furnished by, with or from the use of the Project; (b) with respect to the PFC Eligible Bonds, PFC Revenue; (c) Net Loss Proceeds; and (d) all income or other gain, if any, from any investment of Project Revenues.

The Indenture provides that the Corporation is required to make payments to the Trustee in amounts sufficient to pay the principal of, premium, if any, and interest on the Series 2017 Bonds when due. Pursuant to the Indenture, all Project Revenues (other than PFC Revenue) are to be deposited into the Revenue Fund to be established, maintained and held in trust for the benefit of the Bondholders by the Trustee. PFC Revenue is to be deposited directly in the PFC Account of the Bond Fund and held in trust for the benefit of the Bondholders who own the PFC Eligible Bonds, which, after the Series 2017 Bonds are issued, will consist of the Series 2011A Bonds and the Series 2017A Bonds.

The largest component of this revenue sources is the annual rent paid by the Signatory Airlines under their Terminal Building Leases for use of the Terminal Building. For additional information about the Terminal Building Leases and rental amounts received under those leases as well as from other commercial airlines utilizing the Airport, see "AIRPORT AGREEMENTS—Terminal Building Leases" and "FINANCIAL INFORMATION—Historical Financial Operations." For additional information on other Terminal Agreements and revenues received thereunder, see "AIRPORT AGREEMENTS- DMWEST#16594819 v6 16 Other Terminal Building Revenue; —Parking Facilities Sublease; —De-Icing Facility Sublease; —Road Improvements Lease." PFC Revenue Passenger Facility Charge; Limitation on PFCs Pledged to Pay the Bonds. The PFC Act currently allows public agencies controlling certain commercial service airports (those with regularly scheduled service and enplaning 2,500 or more passengers annually) to charge each enplaning passenger using the airport a $1.00, $2.00, $3.00, $4.00 or $4.50 facility charge, referred to as a PFC. Public agencies wishing to impose and use these PFCs must apply to the FAA for such authority and meet certain requirements indicated in the legislation and regulations issued by the FAA. Regardless of the number of PFC applications which have been approved by the FAA, under current law, an airport can only collect a maximum of$4.50 on each enplaning passenger(less $0.11 administrative fee per enplanement retained by the collecting airline). The purpose of the charge is to develop additional capital funding sources to provide for the expansion of the national airport system. The proceeds from PFCs must be used to finance eligible airport-related projects that preserve or enhance safety, capacity or security of the national air transportation system, reduce or mitigate noise from an airport that is part of such system, or furnish opportunities for enhanced competition between or among air carriers. Since 1993, the County has submitted several applications with the FAA to impose and use PFCs on each enplaning passenger at the Airport. The FAA approved these applications thereby allowing the County to collect a $4.50 PFC to finance Terminal Building Project, the 2006 Project. The FAA has approved applications which, in the aggregate, authorize the County to collect $22,869,216 of PFCs (the "PFC Authorized Amount"). As of June 30, 2017, a total of $12,497,987 of PFCs (including interest earned on the unused balance of the total PFC Authorization Amount) has been collected, with the remaining balance of$10,371,229. All of the unused balance of the PFC Authorization Amount relates to the applications approved by the FAA to impose and use PFCs to finance the costs of the Project (excluding the Terminal Expansion Project). See"THE PROJECT." The County does not anticipate applying to the FAA to approve the imposition and use of PFCs to finance the Terminal Expansion Project. Accordingly, PFC Revenue will not be pledged to pay the Series 2017B Bonds. Furthermore, the Indenture,provides that with respect to any Bonds designated by the Corporation to be PFC Eligible Bonds in the future,the Corporation may determine the amount of revenue derived from PFCs that will be pledged to pay such PFC Eligible Bonds, meaning that not all revenues derived from the PFCs approved to finance the costs of the Project may be pledged. The County may at any time apply to the FAA for the authority to collect and use PFCs for any other Airport related projects which are eligible to be financed with PFCs (such as, for example, runway improvements) but which do not constitute part of the Project. Any PFCs which may be approved by the FAA to be collected and used to finance eligible Airport-related projects which do not constitute part of the Project will not be pledged to pay the Bonds. Authority to collect PFCs extends until May 1, 2036. However, such authorization to collect PFCs could expire earlier if the total PFC Authorized Amount is collected prior to May 1, 2036. With current annual collections (including interest earned on the unused balance), the DMWEST#16594819 v6 17 estimated expiration of collection authority occurs on July 1, 2037. If the amounts authorized to be collected have not been collected by the stated expiration date of May 1, 2036, the County is expected to request the FAA to extend the stated expiration date, however, no assurances can be given that the authorization to collect the PFCs will be extended. See "CERTAIN INVESTMENT CONSIDERATIONS—Availability of PFC Revenue." If the PFC Increase Date occurs (as described and defined in "—Potential Release of a Portion of the PFC Revenue After the PFC Increase Date" below), it is likely that the collection of the PFC Revenue will accelerate, which would result in the Corporation collecting the total remaining PFC Authorized Amount (which, as of June 30, 2017, equals approximately $10,371,229) earlier then the currently scheduled expiration date of May 1, 2036. Furthermore, any PFC Revenue which is not used to pay principal on the PFC Eligible Bonds and interest on the PFC Interest Eligible Bonds and which, following the PFC Increase Date, are not directed by the Corporation to remain on deposit in the PFC Account for a potential release to the County pursuant to the Indenture, will remain on deposit in the PFC Account of the Bond Fund and will be used for Special Redemption of the PFC Eligible Bonds as described under "THE SERIES 2017 BONDS–Redemption–Special Redemption." Pledge of PFC Revenue to Pay Principal on the PFC Eligible Bonds. Under the Indenture, PFCs imposed and used for the Project are included in the Project Revenues (with respect to the PFC Eligible Bonds only) and are required to be credited to the PFC Account maintained by the Trustee in the Bond Fund. The Series 2017B Bonds are not payable from PFC Revenue because the Terminal Expansion Project has not been approved by the FAA as eligible for payment from the PFCs and it is not currently anticipated that the County will apply to the FAA for such approval. Pledge of PFC Revenue to Pay Interest on PFC Interest Eligible Bonds. In January 2007, the FAA approved the County's application to collect PFCs in the amount of$5,581,125 (which, for the avoidance of doubt, is included in the PFC Authorized Amount discussed above) and to utilize such PFCs to finance the 2006 Project, certain financing costs and interest portion of the Series 2006B Bonds. Prior to that application, the County did not include in its PFC applications to the FAA interest component of the bonds issued to finance eligible airport-related projects. Accordingly, under the Indenture, because the Series 2017A Bonds are being issued to refund the Series 2006B Bonds (and refinance the costs incurred in connection with the 2006 Project), PFC Revenue is pledged to pay interest only on the Series 2017A Bonds and such other Bonds issued under the Indenture if the proceeds of such Bonds were used to finance a project the interest portion of which may be paid with PFCs pursuant to an FAA approval (the "PFC Interest Eligible Bonds"). Upon the issuance and delivery of the Series 2017 Bonds, only the Series 2017A Bonds will constitute PFC Interest Eligible Bonds. However, the County may at any time file a new application with the FAA requesting the ability to impose and use PFCs to pay for interest component of PFC-eligible airport-related projects financed with the proceeds of the Bonds or any Additional Bonds; however,the County does not currently plan to file such an application. Potential Release of a Portion of the PFC Revenue After the PFC Increase Date. If the Congress increases the PFC rate above the current rate of$4.50 per each enplaning passenger DMWEST#16594819 v6 18 and the PFC Increase Date (as defined below) occurs, the Trustee will be authorized pursuant to the Indenture to release to the County a portion of PFC Revenue in any Fiscal Year in which the Corporation meets certain debt service coverage ratio requirements and certain other conditions set forth in the Indenture, as described below. The Indenture defines the "PFC Increase Date" as the date of issuance by the FAA of a Final Agency Decision with respect to all then-existing open PFC applications (authorizing collection of PFCs and use thereof for the costs of the Project)permitting collection of PFCs at a level higher than$4.50 per enplaning passenger. In late July of 2017, the Senate Appropriations Committee approved the fiscal year 2018 annual appropriations bill for the U.S. Department of Transportation which is expected to be considered sometimes in September of 2017. This bill increases the PFC rate to $8.50 per enplaning passenger. However, the Federal Aviation Administration Reauthorization Act of 2017 (S.B. 1405) introduced in Congress earlier this year does not include such an increase. Neither the Corporation nor the County can anticipate whether the PFC rate will be increased pursuant to these bills or similar legislation. Pursuant to the Indenture, after the occurrence of the PFC Increase Date, if between May 2 and May 31 of any Fiscal Year the Trustee receives from the Corporation a PFC Release Certificate, it may release to the County a portion of the PFC Revenue on deposit in the PFC Account on May 31 of the same Fiscal Year. "PFC Release Certificate" is defined in the Indenture as a written certificate signed by the President of the Corporation certifying that (i) as of the date of such certificate, no Event of Default has occurred and is continuing under the Indenture and,to his or her knowledge there is no event, act or occurrence which,with the giving of notice or the lapse of time (or both), would become an Event of Default, and (ii) based on the Corporation's Accountant's calculation made within thirty (30) days from the date of the PFC Release Certificate, each of the Historic Debt Service Coverage Ratio and Projected Debt Service Coverage Ratio is at least 1.50 and attaching such calculation signed by the Accountant. "Historic Debt Service Coverage Ratio" means, as of any date of calculation, the ratio derived by dividing (a) the Net Revenues for the immediately preceding Fiscal Year, less any Excess PFC Revenue for such year,by(b)the Debt Service due in such Fiscal Year. "Projected Debt Service Coverage Ratio"means, as of any date of calculation, the ratio derived by dividing (a) the aggregate Project Revenues deposited with the Trustee as of the date of calculation and projected to be deposited with the Trustee during the remaining portion of the then current Fiscal Year less the Operations and Maintenance Expenses actually paid by the Trustee as of the date of calculation and budgeted to be paid during then current Fiscal Year by (b) the Debt Service coming due in such Fiscal Year, less that portion of the Debt Service that is permitted to be paid from the PFC Revenue in such Fiscal Year. For purposes of determining the Project Revenues not yet deposited with the Trustee and Operations and Maintenance Expenses not yet paid as of the date of calculation, the Indenture requires the Corporation to use its budget for the applicable Fiscal Year adopted by its board of directors (as such budget may be revised from time to time pursuant to the procedures established by the Corporation), provided that for purposes of this definition, the Project Revenues, Operations and Maintenance Expenses and the amount of the aggregate Debt Service are to be calculated in accordance with the Indenture. DMWEST#16594819 v6 19 "Excess PFC Revenue" means, with respect to each Fiscal Year, the difference, if any, between the amount of PFC Revenue deposited with the Trustee during such year and that portion of Debt Service due in such year with respect to the PFC Eligible Bonds that is eligible to be paid from the PFC Revenue. As described above, the portion of Debt Service that is eligible to be paid from the PFC Revenue will, upon issuance of the Series 2017 Bonds, consist of the principal on the Series 2011A Bonds and the Series 2017A Bonds and interest on the Series 2017A Bonds. The Indenture provides that if no Series 2011A Bonds and the Series 2017A Bonds are outstanding, the foregoing provisions relating to the release of the PFC Revenue after the PFC Increase Date will not apply because the Corporation will be able to determine the amount of the PFC Revenue that will be pledged to pay any Bonds which the Corporation designates in the future as PFC Eligible Bonds. Availability of PFC Revenue and Termination of Authority to Impose a Passenger Facility Charge. The amount of PFC Revenue expected to be received is less than the original principal amount of the Series 2011A Bonds and the Series 2017A Bonds. The actual amount of PFC Revenue received each Fiscal Year will vary depending on the number of qualifying passenger enplanements at the Airport. See Table 2 under "FINANCIAL INFORMATION— Historical Financial Operations" for data on the PFC Revenue collected in the last five Fiscal Years. No assurance can be given that the amount of PFC Revenue will continue at the levels achieved in such prior Fiscal Years or at the levels assumed in the Report of the Airport Consultant. Further, the FAA may terminate the County's authority to impose the PFC, subject to informal and formal procedural safeguards, as described below. The County has covenanted in the Project Agreements that the County will take any action or avoid taking any action as is necessary in order to obtain and maintain the FAA approval of the use of PFC Revenue generated at the Airport for the Project and to comply with all valid and applicable federal laws and regulations pertaining thereto necessary to maintain the PFC. However, no assurance can be given that the County's authority to impose the PFCs, nor the Corporation's use of such PFCs, will not be terminated by Congress or the FAA, that the PFC program will not be modified or restricted by Congress or the FAA so as to reduce PFC Revenue available to the Corporation. Furthermore, if the PFC Increase Date occurs, it is possible that the collection of the PFC Revenue will accelerate, which would result in the Corporation collecting the total remaining PFC Authorized Amount earlier than the currently scheduled expiration date of May 1, 2036. See "—Passenger Facility Charge; Limitation on PFCs Pledged to Pay the Bonds" above under this caption. In addition, the Signatory Airlines have agreed in the current Terminal Building Leases to make PFC Backstop Payments in the event PFC Revenue expected to be collected at the Airport are insufficient to pay that portion of debt service on the PFC Eligible Bonds that is eligible to be paid with the PFCs (i.e. principal on the Series 2011A Bonds and principal and interest on the Series 2017A Bonds). See "AIRPORT AGREEMENTS—Terminal Building Leases — PFC Backstop Payments." As of July 1, 2017, no PFC Backstop Payment had been required to be made by the Signatory Airlines. If the Corporation enters into new Terminal Building Leases with the Signatory Airlines, such Leases may or may not contain provisions relating to PFC Backstop Payment. DMWEST#16594819 v6 20 The County's authority to impose, collect and have the Corporation use the PFC Revenue for the Project may be terminated if(i)the FAA determines that the PFC Revenue is excessive or cannot determine that such revenue is being used for approved projects in accordance with the FAA approval granted to the County to impose and collect PFCs or with the PFC Act, or if project implementation does not commence within the time period specified in the PFC Act or (ii) the County otherwise violates the PFC Act or regulations. The County's authority to impose the PFC may also be terminated if the FAA determines the County is in violation of certain provisions of the Airport Noise and Capacity Act of 1990, as amended (the "Noise Act") and its implementing regulations relating to the implementation of noise and access restrictions for certain types of aircraft. The FAA termination provisions provide a variety of procedural safeguards, including an informal resolution procedure before commencement of proceedings to terminate the County's authority to impose a PFC, which the FAA may commence only if the FAA determines that informal resolution is not successful. In addition, termination proceedings include a period of time to allow the County to correct any defect the FAA has identified or to attempt to work out a compromise with the FAA that will allow the PFC revenue stream to continue uninterrupted. The regulations under the Noise Act also contain procedural safeguards to ensure that the County's authority to impose a PFC would not be summarily terminated. Most significantly, the County can under any circumstance prevent termination of its PFC authority by suspending the effectiveness of any noise or access restriction in question until the legal sufficiency of the restriction and its impact on the County's PFC authority has been determined. Finally, if the FAA determines that revenue derived from a PFC is excessive or is not being used in accordance with the PFC Act, the Administrator may set off such amounts as may be necessary to ensure compliance with the PFC Act against federal grants otherwise payable to the County or the Corporation under the Airport and Airway Improvement Act of 1982. If any approval in connection with the Corporation's authority to use the PFCs for the Project is withdrawn or terminated, the FAA could terminate the County's authority to impose the PFC for the Project. Neither the County nor the Corporation has received any notice from the FAA raising issues relating to the County's authority to impose and collect the PFC. Deed of Trust Until the Deed of Trust Termination Date, the Series 2017 Bonds will also be secured, on parity with the Series 2011A Bonds,by a pledge of the Corporation's leasehold interest pursuant to the Deed of Trust in the Project Site leased under the Ground Leases (consisting of the Terminal Building Ground Lease and the De-Icing Facility Ground Lease), together with all improvements thereon, and the Corporation's right, title and interest in and to the Road Improvement Site, together with all improvements thereon. Pursuant to the Ground Leases, the Corporation is leasing the Project Site from the County for lease amounts determined pursuant to formulas set forth therein. The Terminal Building Ground Lease expires on December 31, 2045 but is required to be terminated earlier in the event all Bonds issued under the Indenture to finance Terminal Building Project and related additions, including the Terminal Expansion Project, have been defeased. The De-Icing Facility Ground Lease expires on December 31, 2031, but is required to be terminated earlier in the event the Series 2017A Bonds have been DMWEST#16594819 v6 21 defeased. See "THE PROJECT — The Ground Leases." The Indenture generally defines the "Deed of Trust Termination Date" as the date on which the Deed of Trust is fully released and discharged as evidenced by a recorded copy of an executed Request for Full Release of Deed of Trust and Release, which may not occur earlier than the date on which the Series 2011A Bonds are no longer Outstanding pursuant to the terms of the Indenture. Rate Maintenance Covenant Under the terms of the Indenture, the Corporation has covenanted at all times to fix, revise, charge and collect rentals, rates, fees and other charges for the use of the Project in order that in each Fiscal Year the Project Revenues (net of the Excess PFC Revenue and certain Net Loss Proceeds)will at all times be at least sufficient to provide for: (i) the payment of Operation and Maintenance Expenses and the aggregate Debt Service for the Fiscal Year,plus (ii) the larger of either: (A) the amounts needed for making the required cash deposits in the Fiscal Year to the credit of the Debt Service Reserve Fund, the Subordinate Bond Fund, the Operation and Maintenance Reserve Account and to the Capital Fund to maintain the Minimum Capital Fund Balance; or (B) an amount not less than 30% of the aggregate Debt Service for the Fiscal Year; provided that in calculating the amount required under this subparagraph (ii)(B): (i) Other Available Funds may be used and taken into account, (ii) management fees paid under any management agreement with the Project Manager and Ground Lease payments may be excluded from the calculation of the Operation and Maintenance Expenses, and (iii) in the event Additional Bonds are issued to finance the purchase, acquisition, construction, equipping, alteration or improvement of the FBO Terminal, the amount required under this subparagraph(ii)(B)will be 20%of aggregate Debt Service for the Fiscal Year, starting with the Fiscal Year in which such Additional Bonds are issued. "Debt Service" excludes, for each calculation period, amounts which are irrevocably committed to make such payments during such period, including without limitation any amounts in any escrow account and capitalized interest account. "Other Available Funds" includes, for each Fiscal Year, the amounts, if any, that the Corporation determined appropriate to transfer from the Capital Fund to the Revenue Fund; provided that the Minimal Capital Fund Balance (which is the amount of$346,000) or portion thereof available in the Capital Fund is to be considered as Other Available Funds without transfer to the Revenue Fund. See"—Flow of Funds"below. The Corporation has also covenanted that if the Project Revenues (net of the Excess PFC Revenue and certain Net Loss Proceeds) in any Fiscal Year, together with any Other Available Funds, are less than the amounts specified above, upon the receipt of the audit report for the DMWEST#16594819 v6 22 Fiscal Year, it will request the Airport Consultant to make recommendations as to the revision of the schedule of rentals, rates, fees and charges; and upon receiving such recommendations or giving reasonable opportunity for such recommendations to be made, the Corporation, on the basis of such recommendations and other available information and to the extent legal to do so, will revise the schedule of rentals, rates, fees and charges for the use of the Project, as may be necessary to produce Project Revenues as required. See Section 5.03 in"APPENDIX D—FORM OF THE INDENTURE." If the Corporation complies with the provisions described in the paragraph above, no Event of Default resulting from the failure to meet the rate maintenance covenant occurs under the Indenture, even though the Project Revenues (net of the Excess PFC Revenue and certain Net Loss Proceeds), together with any Other Available Funds, are not actually sufficient to provide funds in the amounts required for such Fiscal Year. All such rentals, rates, fees and other charges for the use of the Project are required to be reasonable in relation to the cost of providing, operating and maintaining the particular portion of the Project and the services furnished by such portion. See Table 2 under"FINANCIAL INFORMATION—Historical Financial Operations"for actual debt service coverage achieved by the Corporation in Fiscal Years 2012 through 2016. Debt Service Reserve Fund The Indenture establishes the Debt Service Reserve Fund for the Series 2011A Bonds,the Series 2017 Bonds and any Additional Bonds. Upon the issuance of the Series 2017 Bonds, the aggregate Debt Service Reserve Fund Requirement for the Series 2011A Bonds and the Series 2017 Bonds will be $ * and will be satisfied by applying amounts already on deposit in the Debt Service Reserve Fund as of the date of issuance of the Series 2017 Bonds, as well as $ * from the proceeds of the Series 2017 Bonds. In the event any moneys in the Debt Service Reserve Fund are transferred to pay principal of or interest on the Series 2011A Bonds and Series 2017 Bonds by making up a deficiency in the Bond Fund pursuant to the provisions of the Indenture, the Corporation must replenish the Debt Service Reserve Fund to the Debt Service Reserve Fund Requirement, as described under the"—Flow of Funds"below. The Corporation may at any time deposit a Credit Facility in the Debt Service Reserve Fund in full or partial payment of the Debt Service Reserve Fund Requirement, payable on any date on which moneys are required to be withdrawn from the Debt Service Reserve Fund, as more fully described in the Indenture. See "APPENDIX D—FORM OF THE INDENTURE" for additional information regarding the Debt Service Reserve Fund. Flow of Funds The application of Project Revenues of the Corporation is governed by the Indenture. The Trustee is required to deposit all Project Revenues and the interest earned on certain funds and accounts established thereunder as and when received into the Revenue Fund, except that all PFC Revenue shall be deposited directly into the PFC Account in the Bond Fund. See "APPENDIX D—FORM OF THE INDENTURE" for provisions relating to such funds and DMWEST#16594819 v6 23 ■ accounts under the Indenture. Moneys deposited from time to time in the Revenue Fund (whether from deposits or from funds remaining after application of funds for the prior month) shall be applied by the Trustee,to the extent available, to the following purposes and in the order of priority established, as follows: first, on each May 1, to the Excess Investment Earnings Fund, in an amount equal to any deposits required to be made therein pursuant to the Indenture; second, to the Operating Fund, on the first day of each calendar month, until the amount deposited therein shall equal 110% of the budgeted and invoiced Operation and Maintenance Expenses for such month (excluding any management fees paid under any management agreement with the Project Manager and ground lease payments, subject to the Indenture provisions (as certified by the Corporation to the Trustee)),plus all fees and charges of the Trustee, the Airport Consultant, Bond Counsel and certain other professionals; third, to the Interest Account, on October 1, 2017, the full amount of interest due on the Bonds on the next Interest Payment Date, and on the first day of each calendar month thereafter, the Monthly Payment in respect of interest payable on the Bonds on the next succeeding Interest Payment Date; fourth, to the Principal Account, (i) on October 1, 2017, the full amount of principal coming due on the Series 2017A Bonds maturing on November 1, 2017; (ii) on the first day of each calendar month thereafter, the Monthly Payment in respect of principal payable on the Bonds on the next succeeding May 1, whether as a result of maturity or scheduled mandatory redemption; fifth, to the Debt Service Reserve Fund, on the first day of each calendar month, an amount, if any, necessary for the amount on deposit therein to equal then applicable Debt Service Reserve Fund Requirement; provided however, that if a deficiency in the Debt Service Reserve Fund occurred as a result of a draw thereon, then the monthly deposit shall be made in such amount as would fund such deficiency in full over a period of 12 consecutive months from the date of the draw; sixth, to the Capital Fund, on the first day of each calendar month, an amount, if any, necessary for the amount on deposit therein to equal the Minimum Capital Fund Balance; seventh, on each May 2, provided all deposits under clauses "first" through "sixth" above have been made in the required amounts, to the Operating Fund to pay any management fees under any management agreement with the Project Manager and payments under the Ground Leases,in each case,due in the then current Fiscal Year; eighth, to the Operation and Maintenance Reserve Account in the Operating Fund, on the first day of each calendar month, an amount, if any, necessary for the amount on deposit therein to equal the Minimum Operation and Maintenance Reserve; DMWEST#16594819 v6 24 ninth, to the Subordinate Bond Fund, on the first day of each calendar month, such amounts as may be required to pay any Subordinate Bonds, including reasonable reserves therefor; tenth, to the County, on the first day of each calendar month, in satisfaction of amounts due the County as a result of the exercise of its option to cure any default under the Indenture; and eleventh, to the Capital Fund, on each May 2, the amount remaining in the Revenue Fund. The payments set forth above shall be cumulative in nature and, to the extent not paid from moneys in the Revenue Fund, shall constitute a continuing, cumulative and primary obligation against such Revenue Fund in each succeeding month until paid. Additional Bonds The liens and security interests created by the Indenture are for the equal and ratable benefit of all Bonds, including the Series 2011A Bonds and Series 2017 Bonds, issued under the Indenture. At the time of issuance of the Series 2017 Bonds, there will be no other Bonds outstanding other than the Series 2011A Bonds and the Corporation does not presently intend to issue any Additional Bonds in the immediately foreseeable future. Nevertheless, the Corporation is permitted to issue Additional Bonds on a parity with the Series 2011A Bonds and Series 2017 Bonds at any time upon compliance with certain requirements of the Indenture. See "APPENDIX D—SUMMARY OF CERTAIN PROVISIONS OF THE INDENTURE—Issue of Additional Bonds; Refunding Bonds; Special Facilities Bonds; Special Facilities Leases; No Prejudicial Competition Additional Bonds." Limited Liability The Series 2017 Bonds are nonrecourse obligations of the Corporation secured only by the Trust Estate and the Deed of Trust (until the Deed of Trust Termination Date), subject to the terms and provisions of the Indenture and the Project Agreements. No revenues of the County from the operation of the Airport or any other source are pledged as security for the Series 2017 Bonds. The obligations of the County to make payments under the Parking Facilities Sublease, the De-Icing Facility Sublease and the Road Improvements Lease are subject to the annual appropriation of such amounts by the County, and do not constitute an obligation of the County to levy taxes. Financial information concerning the County has not been included in this Official Statement. A copy of the County's audited financial statement may be obtained from the County's website at http://www.eaglecounty.us. None of the contents of such website are deemed incorporated into this Official Statement by this reference. See "CERTAIN INVESTMENT CONSIDERATIONS—Parking Facilities Sublease, De-Icing Facility Sublease and Road Improvements Lease;Annual Appropriation Risk." THE SERIES 2017 BONDS SHALL NOT BE A DEBT OR FINANCIAL OBLIGATION OF THE COUNTY, THE STATE OR ANY POLITICAL SUBDIVISION THEREOF WITHIN THE MEANING OF ANY PROVISION OR LIMITATION OF THE DMWEST#16594819 v6 25 CONSTITUTION OR STATUTES OF THE STATE, AND SHALL NEVER CONSTITUTE NOR GIVE RISE TO A PECUNIARY LIABILITY OF THE COUNTY, THE STATE OR ANY POLITICAL SUBDIVISION THEREOF OR A CHARGE AGAINST THEIR GENERAL CREDIT OR TAXING POWERS. THE CORPORATION HAS NO TAXING POWER. OUTSTANDING OBLIGATIONS AND DEBT SERVICE SCHEDULE Outstanding Bonds The Corporation previously issued and there is currently outstanding $5,135,000 in aggregate principal amount of its Series 2011A Bonds. The Series 2011A Bonds are secured by the Trust Estate and the Deed of Trust (until the Deed of Trust Termination Date) on parity with the Series 2017 Bonds. The Series 2011A Bonds were issued to refund previously issued bonds of the Corporation proceeds of which were used to fund a portion of the costs of the acquisition, construction and equipping of the Terminal Building Project. Debt Service Requirements The following table sets forth the debt service requirements on the Series 2011A Bonds and the Series 2017 Bonds and does not include the debt service requirements associated with the Series 2006B Bonds expected to be refunded with proceeds of the Series 2017A Bonds.

Source:RBC Capital Markets,LLC CERTAIN INVESTMENT CONSIDERATIONS The purchase and ownership of the Series 2017 Bonds involve certain investment risks and, therefore, the Series 2017 Bonds may not be suitable for all investors. In considering the matters set forth in this Official Statement, prospective investors should carefully review all investment considerations set forth throughout this Official Statement, and should specifically consider certain risks associated with the Series 2017 Bonds. There follows a discussion of some, but not necessarily all, of the possible risk factors which should be carefully evaluated by prospective purchasers of the Series 2017 Bonds prior to purchasing any Series 2017 Bonds. Dependence on Levels of Airline Traffic and Activity The Project Revenues of the Corporation are dependent primarily on the level of aviation activity and enplaned passenger traffic at the Airport. Although enplaned passenger traffic at the Airport did increase from 2015 to 2016, such traffic has generally been decreasing since 2012. See "FINANCIAL INFORMATION—Airport Operations Historical Passenger Traffic and DMWEST#16594819 v6 27 Airport Operations" and "TABLE 4—Eagle County Regional Airport Historical Scheduled Airline Passenger Traffic 2012-2017." Future levels of aviation activity and enplaned passenger traffic at the Airport will be dependent upon many local, regional, national and international factors including: tourism in and around the County, routes and airfares offered at competing airports within a reasonable driving distance of the County, national and international economic conditions, population and economy of the Airport service region, national and local unemployment rate, political conditions including wars, other hostilities and acts of terrorism, aviation security and public health concerns, the financial health of the airline industry and of individual airlines, airline mergers, the sale of airlines, alliances and consolidations, availability and price of aviation and other fuel, employee cost and availability and labor relations(both with respect to the Corporation and the airline industry), capacity of the national air transportation system and of the Airport, accidents involving commercial passenger aircraft, visa requirements and other limitations on the ability of foreign citizens to enter the United States, currency exchange rates, and the occurrence of pandemics and other natural and man-made disasters, some of which are discussed in further detail hereafter in this section. See "AIRLINE INFORMATION." The airline industry is cyclical and subject to competition and variable demand. Traffic volumes are responsive to economic circumstances and seasonal patterns. Other factors, such as fuel and regulatory costs, can also have a significant impact on the industry. As a result, airline financial performance can fluctuate dramatically from one reporting period to the next. In addition to revenues received from airline activity and passenger traffic generated by the Signatory Airlines, the Corporation derives a significant portion of its revenues from concessionaires including merchandisers, car rental companies, restaurants, and others. See "FINANCIAL INFORMATION." Past declines in Airport passenger traffic have adversely affected, and future declines may adversely affect, commercial operations of many of such concessionaires and car rental companies. Severe financial difficulties affecting a concessionaire could lead to a reduction in, or failure to pay, rent due under its lease agreement with the Corporation or could lead to the cessation of operations of such concessionaire. Susceptibility to Recession and Other Economic Trends Historically, airline passenger traffic nationwide has correlated closely with the condition of the U.S. economy and levels of real disposable income. Previous recessions and periods of stagnant economic conditions in the U.S. and Colorado contributed to reduced passenger traffic at the Airport. Further,the 2008-2009 recession and associated high unemployment and reduced discretionary income contributed to reduced airline travel demand at the Airport during such period. Because the Airport primarily serves as a destination airport for recreational travelers, traffic levels at the Airport are particularly susceptible to reduction during recessions or large- scale downward trends in levels of discretionary income. See "—Dependence on Recreation and Tourism; Climate Change"below. Dependence on Recreation and Tourism The number of enplaned passengers at the Airport is dependent in large part upon the strength of the recreation and tourism industry in the County and surrounding areas. The Airport DMWEST#16594819 v6 28 is not subject to the typical demand as an origin-destination airport, but rather, is primarily a destination airport that is reliant on the demand of the winter and summer vacation traveler. The primary recreation attractions in the County are the Vail and Beaver Creek resorts/ski areas, located within approximately 35 miles of the Airport. Over the last two decades, summer tourism has increased in the County due to a number of new golf courses and the increased popularity of other summer recreational activities, such as hiking, biking, horseback riding, fly fishing and rafting. However,most airline activity at the Airport still takes place during the ski season. In addition, due to the reliance of the region's economy on the ski industry, changing climate conditions could shorten the length of the ski season and therefore reduce the number of skier visits to the region. If the number of skier visits in the region decreases in the future, then the Project Revenues may decrease. Financial Condition of the Airlines; Industry Consolidation The Corporation's largest source of Project Revenues is the annual rent paid by the Signatory Airlines under the Terminal Building Leases, which, together with rents from all commercial airlines utilizing the Airport, represented on average 56% of the Corporation's total operating revenue (not including the PFC Revenue) during the last five Fiscal Years. The ability of the Corporation to continue to generate such revenues depends largely upon the financial health of the Signatory Airlines serving the Airport and the airline industry as a whole. The financial performance of the airline industry is subject to substantial volatility and prior to 2014, many carriers have experienced extended periods of unprofitability. The 2008-2009 global recession and record fuel prices in 2008, for example, led many airlines to raise fares, add new fees and surcharges and reduce capacity and the size of their fleets, as well as personnel. These measures, coupled with increased passenger traffic and lower fuel prices, resulted in increased revenues and profits for the airlines in 2014 through 2016. In addition, in the last two decades, several airlines have merged or consolidated and others have either reorganized under applicable bankruptcy laws or ceased operations. Additional bankruptcy filings, mergers, consolidations and other major restructuring by airlines, including the Signatory Airlines, are possible. No assurance can be given that any of the Signatory Airlines will continue operations at the Airport or with respect to the Terminal Building Project during the term of their respective Terminal Building Leases or thereafter. In the event any Signatory Airline discontinues or reduces its operations at the Airport and use of the Terminal Building Project, its level of activity might not be easily replaced by other carriers. Accordingly, no assurance can be given as to the levels of aviation activity that will be achieved with respect to the Terminal Building Project. The Corporation is not able to predict whether any future airline mergers, consolidations, reorganizations or liquidations will occur. Any reduction in the levels of aviation activity at the Terminal Building Project would adversely affect the Project Revenues. See "AIRLINE INFORMATION," "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS,""FINANCIAL INFORMATION—Airport Operations." DMWEST#16594819 v6 29 Cost,Availability and Price Volatility of Aviation Fuel Fuel is a significant cost component of airline operations and continues to be an important and uncertain determinant of an air carrier's operating economics. Historically, aviation fuel prices have been particularly sensitive to worldwide political instability. Continued or new hostilities in the Middle East or other petroleum producing regions could dramatically impact the price and availability of aviation fuel. Economic expansion in emerging markets also contributes to higher aviation fuel prices. While fuel prices have declined significantly in the past few years, significant and prolonged increases in the cost of aviation fuel have had and are likely in the future to have an adverse impact on the air transportation industry by increasing airline operating costs and reducing airline profitability. The Corporation is not able to predict how continued uncertainty with respect to the cost, availability and volatility of prices of aviation fuel will impact the Airport or the Signatory Airlines. See "—Dependence on Levels of Airline Traffic and Activity," "— Susceptibility to Recession and Other Economic Trends," and "— Financial Condition of the Airlines; Industry Consolidation" above. Air Travel Security,Public Health and Natural Disasters Concerns Concerns about the safety of airline travel and the effectiveness of security precautions, particularly in the context of international hostilities (such as those that have occurred and are currently occurring in the Middle East and North Africa) and terrorist attacks (such as those occurring recently in Nice, Munich, Paris, Brussels, London, and Istanbul, among other cities) may influence passenger travel behavior and air travel demand. Travel behavior may also be affected by anxieties about the safety of flying, the inconveniences and delays associated with more stringent security screening procedures, the potential exposure to severe illnesses (such as the Severe Acute Respiratory Syndrome outbreak in 2003, the H1N1 influenza outbreak in 2009 and 2010, and the recent outbreak of the Zika virus in more than 50 countries and certain parts of the United States) and natural disasters (such as volcano eruptions, earthquakes and tsunamis), all of which could lead to the avoidance of airline travel or the use of alternate modes of transportation. Any decrease in passenger activity at the Airport would cause a corresponding decline in Project Revenues of the Corporation. The Corporation is unable to predict how serious the impact of security, natural disasters, or future pandemics may become, what effect they may have on air travel to and from the Airport, and whether any such effects will be material. Pilot Shortage The airline industry is currently experiencing a nationwide pilot shortage, due to a variety of factors which are expected to continue to negatively impact the number of pilots available to airlines such as the Signatory Airlines in the future. In 2007, Congress amended the FAA's authorizing legislation to increase the mandatory retirement age for pilots from age 60 to age 65. However, even with this change, a large number of pilots in the industry are now approaching the mandatory retirement age. Additionally, fewer people are pursuing careers as pilots, and those who do must now meet stringent, federally-mandated flight-hour requirements before they are permitted to work for commercial airlines. Reductions in the number of military pilots being DMWEST#16594819 v6 30 trained by the U.S. armed forces, who historically have sought employment with commercial airlines upon retirement from military service, have also contributed to a shortage of qualified, entry-level pilots. Any shortage in the number of pilots available to the Signatory Airlines may negatively impact the ability of the Signatory Airlines to continue to offer flights and conduct operations at regional airports such as the Airport and could therefore reduce the Project Revenues available to pay the Bonds. Regulations and Restrictions Affecting the Airport The Airport and the Corporation are subject to various laws, rules and regulations adopted by the local, State and federal governments and their agencies. The Airport is highly regulated by federal agencies including the FAA,the Transportation Security Administration(the "TSA"), Customs and Border Protection and the U.S. Department of Health. The Corporation is unable to predict the adoption or amendment of additional laws, rules or regulations, or their effect on the operations or financial condition of the Airport. Additionally, the operations of the Terminal Building and the Corporation's ability to generate revenues are affected by a variety of contractual, statutory and regulatory restrictions and limitations, including, without limitation, provisions in the Terminal Building Leases, the federal acts authorizing the imposition, collection and use of PFCs, extensive federal legislation and regulations applicable to all domestic airports. It is not possible to predict whether restrictions or limitations on operations of the Terminal Building will be increased or imposed in the future, whether future legislation or regulations will affect anticipated federal funding or PFC collections for capital projects for the Terminal Building, whether additional requirements will be funded by the federal government or require funding by the Corporation or whether such restrictions or legislation or regulations would adversely affect Project Revenues. See "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS—PFC Revenue," "AIRPORT AGREEMENTS—Terminal Building Leases" and "FINANCIAL INFORMATION—Federal Grants." Availability of Federal Funding The Airport depends on federal funding not only in connection with grants and PFC authorizations but also because federal funding provides for TSA, air traffic control, and other FAA staffing and facilities. The FAA currently operates under the FAA Modernization and Reform Act of 2012 (the "2012 Reauthorization Act") and the FAA Extension, Safety, and Security Act of 2016 (the "2016 Reauthorization Act") enacted into law on July 15, 2016. The 2012 Reauthorization Act retained the federal cap on PFCs at $4.50 and authorized $3.35 billion per year for the Airport Improvement Program (the "AIP"). The AIP provides funds to finance capital improvements to commercial, cargo and general aviation airports. AIP grant moneys include entitlement funds that are appropriated annually based on enplaned passengers as well as discretionary funds that are available at the discretion of the FAA. The 2016 Reauthorization Act extends the authority of the FAA and provides funding for the AIP at current levels through September 2017. This summer, the Federal Aviation Administration Reauthorization Act of 2017 (S.B. 1405), which proposes to provide funding for the FAA and its programs (including the AIP) through fiscal year 2021, was introduced to Congress, and is expected to be considered prior to the September 30 expiration of the 2016 Reauthorization Act. This bill maintains the DMWEST#16594819 v6 31 $4.50 PFC cap and proposes to increase AIP funding to $3.75 billion for each of fiscal years 2019 through 2021. Additionally, in late July of 2017, the Senate Appropriations Committee approved the fiscal year 2018 annual appropriations bill for the U.S. Department of Transportation which is expected to be considered sometimes in September of 2017. This bill increases the PFC rate to $8.50 per enplaning passenger and increases AIP funding to $3.6 billion. Since 2012, approximately $35,000,000 in federal AIP grants has been received by the County to finance improvements at the Airport. There is no guarantee that funding at such levels will be available to the County in the future. See "FINANCIAL INFORMATION — Federal Grants." Regardless of legislation that may be enacted in the future, FAA AIP expenditures remain subject to congressional appropriation and no assurance can be given that the FAA will receive spending authority. In addition, the AIP could be affected by the automatic across-the-board spending cuts,known as sequestration. The Corporation is unable to predict the level of available AIP funding the County may receive. If there is a reduction in the amount of AIP grants awarded to the Airport, such reduction could increase by a corresponding amount the capital expenditures that the Corporation and the Airport would need to fund from other sources and/or extend the timing for completion of certain projects. Terminal Building Leases The obligations of the Signatory Airlines under their respective Terminal Building Leases terminate on December 31, 2018, unless a Signatory Airline or the Corporation terminates it sooner. Any Signatory Airline (unless such Signatory Airline is in default under its Terminal Building Lease) may terminate its Terminal Building Lease by giving a written notice that is received by the Corporation during the five business days preceding April 1 or September 1 of each year during the term of the Terminal Building Lease. See "AIRPORT AGREEMENTS— Terminal Building Leases—Term." While the Corporation is currently not aware of any Signatory Airline's plans to terminate its Terminal Building Lease, no assurance can be given that any of the Signatory Airlines will continue its operations at the Airport or with respect to the Terminal Building Project during the term of its respective Terminal Building Lease or thereafter. Any termination by a Signatory Airline of its Terminal Building Lease could significantly impact the availability of Project Revenues to pay the Bonds, particularly if the Corporation were unable to identify another airline to provide service to the Airport and lease space at the Terminal Building on similar terms. While the Corporation intends to enter into new terminal building leases with the Signatory Airlines following the termination thereof, there can be no assurance that all Signatory Airlines will enter into new terminal building leases or that new terminal building leases will be entered into on terms as favorable as the terms of the current Terminal Building Leases. Furthermore, if any Signatory Airline terminates its Terminal Building Lease prior to the end of its term (as permitted by the Terminal Building Leases), the Corporation might not be able to replace such Signatory Airline with another airline. If no airline enters into an agreement with the Corporation at the time of such termination for the use and lease of all or any portion of the Terminal Building Project or if new leases are negotiated on less favorable terms for the DMWEST#16594819 v6 32 Corporation, the amount of Project Revenues may significantly decrease, and the ability of the Corporation to pay for the remaining principal and interest on the Series 2017 Bonds would be significantly impaired. See"AIRPORT AGREEMENTS—Terminal Building Leases"herein for a description of the current Terminal Building Leases with Signatory Airlines. Effect of Bankruptcy on Terminal Building Leases Since December 2000, numerous airlines, including airlines which served the Airport in the past and airlines that currently serve the Airport, have filed for bankruptcy protection. An airline that has executed a Terminal Building Lease or other executory contract with the Corporation and sought protection under the U.S. bankruptcy laws must assume or reject: (a) its Terminal Building Lease within 120 days after the bankruptcy filing subject to a court-approved, one-time 90-day extension(further extensions are subject to the consent of the lessor), and(b) its other executory contracts with the Corporation prior to the confirmation of a plan of reorganization. Bankruptcy courts are courts of equity, however, and as such can, and often do, grant exceptions to such time limitations. In the event of an assumption of any executory contract or lease, an airline would be required to cure any pre- and post-petition monetary defaults and provide adequate assurance of future performance under the applicable executory contract or lease. In the event of an assumption by a debtor airline and assignment to a third party, the assurance of future performance would have to be demonstrated by the proposed assignee. Rejection of a Terminal Building Lease or other executory contract with the Corporation will give rise to an unsecured claim of the Corporation for damages, the amount of which in the case of a Terminal Building Lease or other lease is limited by the U.S. Bankruptcy Code. Claims for such damages are subject to the Corporation's duty to mitigate damages. The amount ultimately allowed in the event of a rejection of a Terminal Building Lease or other executory contract could be considerably less, however, than the maximum amount allowed under the U.S. Bankruptcy Code. Certain amounts unpaid as a result of a rejection of a Terminal Building Lease by an airline in bankruptcy can be passed on to the remaining Signatory Airlines under the Terminal Building Lease, thereby increasing such airlines' cost per enplanement, although there can be no assurance that such other airlines would be financially able to absorb the additional costs. Currently, no Signatory Airlines are in bankruptcy proceedings. Availability of PFC Revenue; PFC Backstop Payments The amount of actual PFC Revenue received by the Corporation in the future years will vary based upon the actual number of PFC-eligible passenger enplanements at the Airport. No assurance can be given that any level of enplanements will be realized or that the PFC Revenue and the schedule for receipt thereof which are assumed in the Report of the Airport Consultant will be attained. Additionally, the FAA may terminate the County's authority to impose PFCs, subject to informal and formal procedural safeguards, if(i) the FAA determines that the PFC Revenue is excessive or cannot determine that such revenue is being used for approved projects in accordance with the FAA approval granted to the County to impose and collect PFCs or with the PFC Act, or if project implementation does not commence within the time period specified in the PFC Act or (ii) the County otherwise violates the PFC Act or regulations. The County's DMWEST#16594819 v6 33 authority to impose the PFC may also be terminated if the FAA determines the County is in violation of certain provisions of the Noise Act and its implementing regulations relating to the implementation of noise and access restrictions for certain types of aircraft. No assurance can be given that the County's authority to impose a PFC would not be terminated by Congress or the FAA, that the PFC program will not be modified or restricted by Congress of the FAA so as to reduce PFC Revenue available to the County. However, see "AIRPORT AGREEMENTS" for a description of Signatory Airlines' obligations during the remaining terms of their respective Terminal Building Leases to make PFC Backstop Payment if the PFC Revenue expected to be collected at the Airport are insufficient to pay that portion of the annual debt service on the PFC Eligible Bonds that is eligible to be paid with the PFC Revenue (i.e. principal on the Series 2011A Bonds and interest and principal on the Series 2017A Bonds). There is no assurance, however, that the Signatory Airlines will agree to extend the current Terminal Building Leases or enter into new terminal building leases by the time the existing Leases expire or will enter into new leases on terms that are as favorable to the Corporation as the existing Terminal Building Leases, including the PFC Backstop Payment provision. See also "APPENDIX A—REPORT OF THE AIRPORT CONSULTANT" and "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS—PFC Revenue—Availability of PFC Revenue and Termination of Authority to Impose a Passenger Facility Charge" for a discussion of situations where the County's right to impose and collect PFCs could be terminated. In addition, if the PFC Increase Date occurs, it is likely that the collection of the PFC Revenue will accelerate, which would result in the Corporation collecting the total remaining PFC Authorized Amount earlier than the currently scheduled expiration date of May 1, 2036. Once all of the PFCs authorized to be collected and used for the Project are collected, PFCs will no longer be available to pay the PFC Eligible Bonds unless the County applies to the FAA to collect and use PFCs for new eligible projects relating to the Project. See "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS—PFC Revenue—Passenger Facility Charge; Limitation on PFCs Pledged to Pay the Bonds;—Availability of PFC Revenue and Termination of Authority to Impose a Passenger Facility Charge." Deed of Trust Termination Date Until the Deed of Trust Termination Date, the Series 2017 Bonds will also be secured, on parity with the Series 2011A Bonds,by a pledge of the Corporation's leasehold interest pursuant to the Deed of Trust in the Project Site leased under the Ground Leases, together with all improvements thereon, and the Corporation's right, title and interest in and to the Road Improvement Site, together with all improvements thereon. Upon the Deed of Trust Termination Date, which may occur no earlier than the date on which the Series 2011A Bonds are no longer Outstanding pursuant to the terms of the Indenture, the Deed of Trust will be fully released and discharged, and will no longer secure the payment of the Series 2017 Bonds. DMWEST#16594819 v6 34 Parking Facilities Sublease, De-Icing Facility Sublease and Road Improvements Lease; Annual Appropriation Risk The obligations of the County to make payments under the Parking Facilities Sublease, De-Icing Facility Sublease and Road Improvements Lease do not constitute obligations of the County to levy taxes or apply its general resources beyond the current Fiscal Year. The County is required to pay rentals under these subleases and the lease only if funds are appropriated by the County in each Fiscal Year. There is no assurance that the County will appropriate the rentals from Fiscal Year to Fiscal Year and therefore not cause the expiration of the Parking Facilities Sublease, the De-Icing Facility Sublease, or the Road Improvements Lease. There is no penalty to the County if it does not appropriate the rentals due under the Parking Facilities Sublease, the De-Icing Facility Sublease, and the Road Improvements Lease for any Fiscal Year and therefore cause the Parking Facilities Sublease, the De-Icing Facility Sublease, and the Road Improvements Lease to expire. The likelihood that the Parking Facilities Sublease will continue in effect until the Series 2011A and the Series 2017B Bonds are paid and that the De-Icing Facility Sublease and the Road Improvements Lease will continue in effect until the Series 2017A Bonds are paid is dependent upon factors which are beyond the control of the Corporation. These factors include but are not limited to: (a) economic conditions in the County and the State and the continued legal authority and ability of the County to generate sufficient funds from property taxes and other sources to pay obligations associated with the Parking Facilities Sublease, De-Icing Facility Sublease and Road Improvements Lease and other obligations of the County and (b) the County's continued desire to use the Project, which is dependent on a variety of other factors beyond the control of the Corporation. Assumptions in the Report of the Airport Consultant The Report of the Airport Consultant incorporates numerous assumptions as to the Project Revenues and other matters and states that any forecast is subject to uncertainties. In particular, the Report assumes, among other things, that (i) airline traffic demand at the Airport will remain level through the end of the projection period of 2023 (see "FINANCIAL INFORMATION—Airport Operations Historical Passenger Traffic and Airport Operations" and "TABLE 4—Eagle County Regional Airport Historical Scheduled Airline Passenger Traffic 2012-2017"), (ii) all Signatory Airlines will extend and continue to operate under their Terminal Building Leases through the end of the projection period of 2023 on terms and conditions, including rental amounts, that are substantially similar to the current Terminal Building Leases, and (iii) the rental car companies currently serving the Airport will extend their concession agreements with the Corporation through the end of the projection period with agreement provisions, minimum annual guarantees and rental amount requirements that are substantially similar to the current agreements. Inevitably, some assumptions used to develop the forecasts will not be realized, and unanticipated events and circumstances may occur. Therefore, the actual results achieved during the forecast period will vary, and the variations may be material. See "INTRODUCTION—Report of the Airport Consultant" and"APPENDIX A—REPORT OF THE AIRPORT CONSULTANT." DMWEST#16594819 v6 35 Construction of Terminal Expansion Project Construction of the Terminal Expansion Project is planned to commence in March 2018 and,pursuant to the DB Contract,be substantially completed on the Substantial Completion Date of November 15, 2019. The expansion would bring additional concessionaire space, among other uses. Although the Corporation plans to erect temporary facilities to accommodate concessionaires, advertisement space and other Airport services and to reduce the disruption to the operation of the Terminal Building during the construction period, such temporary facilities will not completely eliminate such disruption. The ability of the Corporation to complete construction of the Terminal Expansion Project within budget and on schedule may be adversely affected by various factors including: (a) estimating errors, (b) design and engineering errors, (c) inefficiency in processing and awarding contracts, (d) unforeseen site conditions, (e) labor difficulties, (f) adverse weather conditions, (g) unavailability of building materials, (h) contractor defaults and(i) litigation. The Corporation entered into the DB Contract with the Design-Builder for the design and construction of the Terminal Expansion Project for a guaranteed maximum price of$29,145,837 ("GMP"). Under the DB Contract, the GMP includes all costs reasonably and actually incurred by the Design-Builder in the design, construction and other services required by the DB Contract. The GMP is subject to an adjustment in certain limited circumstances set forth in the DB Contract, such as presence of certain hazardous conditions on the project site or differing site conditions, force majeure events, and changes in the scope of work. Although GMP mitigates the risk of completing the construction within budget, the Corporation currently estimates that the Total Expansion Project will cost approximately $33,000,000, which is approximately $3,855,000 higher than the GMP. Such additional amount includes costs to be paid directly by the Corporation (such as the costs of the building permits and passenger boarding bridges) and the contingency amount and is expected to be paid from amounts on deposit in the Capital Fund (other than the Minimum Capital Fund Balance) to the extent proceeds of the Series 2017B Bonds are not sufficient therefor. As of August 15, 2017, $6,667,317 was on deposit in the Capital Fund, including the Minimum Capital Fund Balance of $346,000. See "THE PROJECT—The Design-Build Contract for the Terminal Expansion Project" and "APPENDIX D—FORM OF THE INDENTURE" for provisions relating to the Capital Fund. See "THE PROJECT—The Design-Build Contract for the Terminal Expansion Project." Even though prior projects of the Corporation were constructed on time and within budget, such projects were completed using different contractors, and there is no guarantee that the Terminal Expansion Project will be similarly completed on time and for the amount currently budgeted by the Corporation. The Design-Builder will provide performance and payment bonds with respect to the construction of the Terminal Building Expansion naming the Corporation and the Trustee as additional obligees. In addition, the Corporation will collaterally assign to the Trustee the DB Contract, together with any contracts with subcontracts and plans and specifications for the Terminal Construction Project, and the Design-Builder will consent to the assignment of the DB Contract. Furthermore, all insurance policies obtained by the Design-Builder during the construction period are required to name the Corporation and the Trustee as additional insureds. DMWEST#16594819 v6 36 While these measures and requirements would address some of the construction related risks, no assurances are given that the construction will be completed on time and within current budget. Competition There are existing airports, such as Denver International Airport, Aspen airport (which serves Pitkin County and the City of Aspen), and Grand Junction Regional Airport(which serves the City of Grand Junction, Mesa County, and the Western slope generally), offering alternatives for air travelers wishing to travel to the Airport's service area and similar destinations, and there may be future competitors, some of which are or may be operated by persons possessing greater financial resources than the Corporation, and which may be better able to withstand the effect of competition. Airport operators compete with each other on the basis of location, rates and concessions, and the quality of infrastructure and service offered at the Airport. The Corporation believes that there will be sufficient demand for the Airport to compete effectively; however, there is no assurance that the anticipated demand for the Project in the competitive market will be as projected by the Corporation and the Airport Consultant. Employee Retention Due to the high cost of living in the communities that surround Vail and Beaver Creek, employee retention is an ongoing challenge for service-sector companies like the concessionaires that serve the Airport, as well as for the County that manages the Project and owns and operates the Airport. The American Community Survey, implemented by the U.S. Census Bureau, has found that 45% of families that reside in the County allocate more than 30% of their incomes to housing costs. Further, the Vail Valley Partnership found that, in 2015, housing vacancy rates were under 5%, resulting in a highly stressed rental market. See "APPENDIX B—ECONOMIC AND DEMOGRAPHIC INFORMATION REGARDING EAGLE COUNTY" for a description of certain economic and demographic information concerning the County. High housing costs and cost of living may negatively affect the ability of employers (including the County) to employ and retain qualified personnel. Enforceability of Remedies The practical realization of value from the Project upon any default will depend upon the exercise of various remedies specified by the security documents securing the Series 2017 Bonds. See "APPENDIX D—SUMMARY OF CERTAIN PROVISIONS OF THE INDENTURE—Events of Default and Remedies" for a description of events of default and remedies under the Indenture. These and other remedies may, in many respects, require judicial actions, which are often subject to discretion and delay. Under existing law (including particularly federal bankruptcy law), the remedies specified by such documents may not be readily available or may be limited. A court may decide not to order the specified performance of the covenants contained in the security documents. In addition, federal bankruptcy law permits the adoption of a reorganization plan even though the plan has not been accepted by the owners of a majority in aggregate principal amount of the Series 201 IA Bonds and the Series 2017 Bonds, if such owners are provided with the benefit of their original lien or the "indubitable equivalent" thereof. If a bankruptcy court concludes that the owners of the Series 2017 Bonds have "adequate protection," it may substitute other security subject to the lien of the owners of DMWEST#16594819 v6 37 the Series 2017 Bonds and (b) subordinate the lien of the owners of the Series 2017 Bonds (i) to claims by persons supplying goods and services to the Corporation after bankruptcy and (ii) to the administrative expenses of the bankruptcy proceeding. In the event of bankruptcy of the Corporation, the amount realized by the owners of the Series 2017 Bonds might depend on a federal bankruptcy court's interpretation of"indubitable equivalent" and "adequate protection" under then existing circumstances. A bankruptcy court may also have the power to invalidate certain provisions of the security documents which make bankruptcy and related proceedings by the Corporation an event of default thereunder. The various legal opinions to be delivered concurrently with the delivery of the Series 2017 Bonds will be qualified as to the enforceability of the various legal instruments by limitations imposed by state and federal laws, rulings, and decisions affecting remedies and by bankruptcy, reorganization, or other laws affecting the enforcement of creditors' rights generally. Liquidation of Security May Not Be Sufficient in the Event of a Default In the event of a default by the Corporation under the Indenture, the Trustee and/or the Corporation must look solely to the Project and Project Revenues to pay and satisfy the Series 2017 Bonds in accordance with their terms. See "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS." The owners of the Series 2017 Bonds are dependent entirely upon the success of the Project for the payment of the Series 2017 Bonds. In the event the revenues from the Project are insufficient to pay the amounts due on the Series 2017 Bonds,then once the other security for the Series 2011A Bonds and Series 2017 Bonds has been exhausted, the owners of the Series 2011A Bonds and Series 2017 Bonds will have no person or entity to pursue for any deficiency which may exist. The practical use of the Project is limited to its use as an airport terminal, de-icing facility and access roads. If it were necessary to foreclose the lien of the Deed of Trust on the Project (which is an available remedy only until the Deed of Trust Termination Date), net proceeds received may be less than the principal amount of the Series 2011A Bonds and Series 2017 Bonds outstanding. After the Deed of Trust Termination Date, foreclosure on the lien of the Deed of Trust will no longer be available to the owners of the Series 2017 Bonds. See"—Deed of Trust Termination Date" above. Financial Condition of the Corporation The Corporation has no appreciable assets other than its interest in the Project. Therefore, as a practical matter, owners of the Series 2017 Bonds must look to the Project and the Corporation's ability to collect Project Revenue to produce the revenues to pay the amounts due under the Indenture, and in the event of insolvency of the Corporation, the only asset of the Corporation which can reasonably be anticipated to be available to produce revenues to pay the amounts due under the Indenture will be the Project. Uncertainty of Continued Collective Marketing Efforts The County, as well as several municipalities, hotels, restaurant groups, and other businesses within the County, including Vail Resorts, Inc. ("Vail Resorts"), a publicly traded company on the New York Stock Exchange and the operator of the Colorado mountain resorts of Vail, Breckenridge, Keystone and Beaver Creek, are supporters of and contributors to the EGE Air Alliance (the "Alliance") a non-profit, public-private organization whose primary mission is DMWEST#16594819 v6 38 to work with airlines, in partnership with the Airport, to maintain existing flights and secure new flights to and from the Airport. The Airport and the Alliance have previously entered into agreements with some of the airlines serving the Airport to assist and subsidize joint marketing efforts and/or guarantee a certain amount of revenue on the scheduled service by such airlines using the Airport, although the Corporation is not aware of the exact terms of agreements made exclusively with the Alliance. Unlike similar groups in other regions, the Alliance does not receive continual funding through a dedicated self-sustaining revenue source, such as a tax or an allocated budget from a governmental entity, but is instead reliant upon voluntary contributions from the public and private sources described above in order to fund its ongoing efforts. Therefore, the continued existence of the Alliance and its work with the airlines that serve the Airport is uncertain. The Airport does have an established marketing budget to continue development of new service as deemed appropriate by Airport management, but there is no guarantee that such funds allocated from such budget would be sufficient to mitigate any loss of contributions to the Alliance. The efforts of and agreements with the Alliance may encourage some or all of the airlines serving the Airport to continue to schedule service at the Airport. In the event that the Alliance does not continue to receive sufficient funding to continue such efforts, the Corporation is unable to predict what effect this would have on an airline's decision to continue to provide service to the Airport. The Airport's currently scheduled service does include many established routes that are no longer considered to be "shared risk"routes, meaning such routes are no longer subsidized by the Airport or the Alliance. However, there is no guarantee that even well-established routes will continue to be offered by the Signatory Airlines in the future. Additional Debt The Indenture provides that the Corporation may issue Additional Bonds, including Refunding Bonds, secured by Project Revenues and the Project on a parity with the Series 2011A Bonds and the Series 2017 Bonds as described herein under "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS—Additional Bonds." The Corporation is not obligated to issue Additional Bonds, however, and has no present intent of issuing Additional Bonds. Failure to Maintain Enterprise Status Although the County regards the possibility that the Corporation might be disqualified as an "enterprise" in any year during the term of the Series 2017 Bonds as remote, such disqualification of the Corporation as an "enterprise" in any future year may limit the Corporation's ability to collect, retain and expend revenues, including Project Revenues, thereby possibly negatively impacting the security for the Series 2017 Bonds. See "STATE CONSTITUTIONAL AMENDMENT"herein. DMWEST#16594819 v6 39 AIRPORT AGREEMENTS Terminal Building Leases Currently, there are three separate Terminal Building Leases between the Corporation and each Signatory Airline, namely American, Delta, and United. Signatory Airlines account for approximately 99.7% of the airline activity at the Airport. The Terminal Building Leases permit the Corporation to enter into leases with additional airlines providing air transportation to and from the Airport using the terminal building (the "Terminal Building") that have executed agreements with the Corporation which are substantially similar to the Terminal Building Leases. All Terminal Building Leases contain substantially identical terms. Certain of these terms are described below. Term. All Terminal Building Leases (except for the United Terminal Building Lease which commenced effective as of December 1, 2009)were entered into effective as of December 1, 2006 for a three-year term and were extended: (i) effective as of each of December 1, 2009 and December 1, 2012, in each case, for an additional three-year term, and (ii) effective as of December 1, 2015 for additional thirty-seven month term. As such, all Terminal Building Leases expire on December 31, 2018, unless earlier terminated pursuant to their terms. Each Terminal Building Lease provides that following the expiration date, the Lease will automatically convert into a month to month tenancy with all other terms and conditions remaining the same, except that such Lease can be terminated by the Corporation upon 30 days' prior written notice. In addition, under certain circumstances, the Signatory Airlines may terminate their respective Terminal Building Leases prior to the stated expiration date. For example, any Signatory Airline (unless such Signatory Airline is in default under its Terminal Building Lease) may terminate its Terminal Building Lease without cause by giving a written notice that is received by the Corporation during the five business days preceding April 1 or September 1 of each year during the term of the Terminal Building Lease. Additionally, any Signatory Airline may terminate its Terminal Building Lease (unless such Signatory Airline is in default under its Terminal Building Lease), upon 30 days' prior written notice, if: (i) the Corporation is in default of any material provision of the Terminal Building Lease (subject to cure rights of the Corporation), or (ii) such Signatory Airline becomes subject to any order, rule or regulation of any federal or state agency or to a court order which substantially prevents such Signatory Airline's use of the Airport. While, prior to the expiration of the current Terminal Building Leases on December 31, 2018, the Corporation intends to negotiate extensions or enter into new leases with the Signatory Airlines, there is no assurance that the Signatory Airlines will agree to extend the current Terminal Building Leases or enter into new terminal building leases by the time the existing Leases expire or will enter into new leases on terms that are as favorable to the Corporation as the existing Terminal Building Leases. See "CERTAIN INVESTMENT CONSIDERATIONS— Terminal Building Leases. " Rent. The Terminal Building Leases require the Signatory Airlines and any airline that signs a Terminal Building Lease to collectively share in the payment of an annual total rental amount for use of the Terminal Building (the "Total Rent Amount"). The Total Rent Amount includes (i) rent for each Signatory Airline's exclusive-use space within the Terminal Building DMWEST#16594819 v6 40 ■ space and its proportionate share of the joint-use space within the Terminal Building and (ii) each Signatory Airline's proportionate share of the debt service coverage requirements (to the extent such requirement is not funded) and all other debt-related costs associated with the Bonds. Each Signatory Airlines proportionate share of the costs included in the calculation of the Total Rent Amount is determined using the ratio of the number of such Signatory Airline's enplaned passengers at the Airport during the most recent calendar year for which such information is available to the total number of enplaned passengers of all Signatory Airlines during that same calendar year, except that 20% of the rent attributable to joint use space is allocated in equal amounts among the Signatory Airlines. The Total Rent Amount is calculated each year based on the formulas and procedures set forth in the Terminal Building Leases and each Signatory Airline pays its share of such amount in 12 equal monthly installments on the first day of each month of the Terminal Building Lease. In the event a Signatory Airline fails to make payment within fifteen (15) days from the due date, the Corporation, with prior notice to the Signatory Airline, may charge a late service charge equal to the lesser of 2% per month or the highest rate allowed by applicable law on any such overdue amounts and in some cases,the Signatory Airline may be liable for administrative costs and attorneys' fees incurred by the Corporation in attempting to obtain payment. The Terminal Building Leases permit the Corporation to adjust the Total Rent Amount (after consultation with the Signatory Airlines) during any year in which the Corporation projects the Total Rent Amount to vary by 20% or more in the succeeding year if the then existing total rental payments due from the Signatory Airlines would result in an overpayment or underpayment of the revenue (not including the PFC Revenue) derived by the Corporation from the operation and use of the Terminal Building or to ensure such revenue is generated during the fiscal year in sufficient amount to meet the annual budget of the Corporation. The Terminal Building Leases require the Corporation to refund to the Signatory Airlines, within 60 days of the close of the annual financial audit, 50% of any Net Concession Revenues up to $600,000 which would result in a maximum refund of$300,000, on a pro-rata basis based on actual enplanements from the Terminal Building during such fiscal year; provided, that if a Signatory Airline is in default of its Terminal Building Lease, the Corporation may withhold any refund due to such Signatory Airline until the default is cured, and any such Net Concession Revenue share will result in an immediate offset against any amounts due to the Corporation from such Signatory Airline. The Terminal Building Leases further restrict refunding of 50% of any Net Concession Revenues in the event an airline files for bankruptcy. For purposes of the Terminal Building Leases, "Net Concession Revenues" equals the Concession Revenues reduced by the Terminal Building Shortfall. "Concession Revenues" is defined as all Terminal Building revenues derived by the Corporation from food, beverage catering, news and gift vendors, rental cars and other ground transportation providers, parking, advertising, ski rentals and other retail sales and services. "Terminal Building Shortfall" is defined as the Total Rent Amount less the sum of all actual rental payments made by the Signatory Airlines and the non-signatory airlines for use of the Terminal Building. Total Rent Amount received by the Corporation in Fiscal Years ended December 31, 2012 through December 31, 2016 is set forth under the entry"Building Rentals"in Table 2 under the caption "FINANCIAL INFORMATION—Historical Financial Operations." During that period, rents from all commercial airlines utilizing the Airport averaged $2,505,636 per year. DMWEST#16594819 v6 41 This amount represented approximately 56% of the Corporation's total operating revenue (not including the PFC Revenue) on average for each of those years. This percentage does not take into account any revenue sharing amounts or refunds received by the Signatory Airlines. See Table 2 under "FINANCIAL INFORMATION— Historical Financial Operations" for a summary of the Corporation's last five Fiscal Years' terminal building rental income which includes rents from all commercial airlines utilizing the Airport. PFC Backstop Payment. The Terminal Building Leases provide for rental payments as well as PFC Backstop Payments in the event that PFCs expected to be collected at the Airport are insufficient to pay that portion of the annual debt service on the PFC Eligible Bonds that is eligible to be paid with the PFC Revenue (i.e. principal on the Series 2011A Bonds and principal and interest on the Series 2017A Bonds). In such event, the Total Rent Amount due from the Signatory Airlines may be increased (proportionately based on enplanements) to include an amount (the "PFC Backstop Payment") equal to "the deficiency in collected PFCs necessary for payment of that portion of the total annual debt service due on the Bonds that would have been eligible for PFC funding under the Airport's PFC application approved by the FAA"; provided, however, that the PFC Backstop Payment collectively paid by the Signatory Airlines may not exceed $450,000 annually. The Terminal Building Leases generally define "Bonds" as debt of the Corporation issued to finance projects for the construction, expansion, improvement or preservation of the Terminal Building and related facilities and services. The PFC Backstop Payment has not been required from, or paid by, the current Signatory Airlines throughout the term of the Terminal Building Leases. If the Corporation enters into new Terminal Building Leases with the Signatory Airlines, such leases may not contain provisions relating to PFC Backstop Payment. Other Terminal Building Revenues In addition to amounts payable by Signatory Airlines under their respective Terminal Building Leases, other Project Revenues are derived from car rental, news/gift, food/beverage and other concessions, ground transportation permits, advertising display fees, and certain other fees and commissions. See Table 6 under "FINANCIAL INFORMATION—Terminal Building Concessions" for a summary of the Corporation's last five Fiscal Years' concession income. Currently, the Corporation has lease agreements for rental car services with four (4) rental car companies, namely Enterprise Leasing Company (d/b/a Alamo Rent a Car and National Car Rental); Avis Budget Car Rental, LLC (d/b/a Avis and Budget); Frontier Rental, Inc. (d/b/a Dollar Rent A Car and Thrifty Car Rental); and The Hertz Corporation, all of which expire on October 31, 2017 with the option to extend for two additional one-year agreements through October 31, 2019. The Corporation anticipates sending requests for proposals in September of 2017 to rental car companies and expects to enter into new lease agreements with rental car companies who are awarded the contracts. Rental car concession revenues currently consist of payment by each rental car company of: (i)rent at$3.56 per square foot per month for counter space at the Terminal Building, (ii)rent at $44.00 per space per month for ready/return spaces, and (iii) the greater of: (A) a percentage fee at a rate of 10% of its gross rental car revenues from the Airport during each calendar month (the "Percentage Fee"), and (B) any applicable minimum monthly guaranteed payments DMWEST#16594819 v6 42 ("Minimum Monthly Guarantees"), which are generally applicable during the peak ski season months, and are set forth in specified amounts (which vary for each rental car company) in the lease agreements. The lease agreements provide that the rent per space per month for ready/return parking spaces will increase by $3.00 for each extension period, meaning that this rent would be $47.00 per space per month from November 1, 2017 through October 31, 2018 and $50.00 per space per month from November 1, 2018 through October 31, 2019, if these leases are extended through such periods. See Table 6 under"FINANCIAL INFORMATION— Terminal Building Concessions" for a summary of the Corporation's last five Fiscal Years' rental revenues. These lease agreements permit the Corporation to grant up to a total of four concessionaires the right to offer rental car services at the Terminal Building. Accordingly, until the current leases terminate or amended, the Corporation may not enter into additional leases for car rental services. For the Fiscal Years ending December 31, 2012 through December 31, 2016, concession revenue from rental car companies utilizing the Airport averaged $1,616,752 per year, which represents approximately 33% of the Corporation's total operating revenue (not including the PFC Revenue)for those years. The Corporation also receives revenues under agreements with two (2) ground transportation companies, which pay rent per square foot of occupied space and minimum monthly privilege fees at a predetermined amount during the ski season months of December through April. The agreements with each of these companies terminated in October 2016; however, both companies continue to operate and lease space within the Terminal Building on a month to month "holdover" basis, as permitted by such agreements. Such month to month tenancy may be terminated at any time by the applicable company or by the Corporation upon thirty 30 days' written notice. The Corporation has stated that it anticipates soliciting quote requests from vendors in early fall 2017 to continue to provide such services at the Airport, with the expectation that such vendors would enter into similar agreements with the Corporation. There is no guarantee of the terms of such anticipated agreements, or that such agreements will be entered into at all. See Table 6 under "FINANCIAL INFORMATION—Terminal Building Concessions" for the last five Fiscal Years of the Corporation's ground transportation, retail and other concessions revenues. Other concessionaires, such as news, food, and gift vendors and restaurant operators within the Airport, generate revenues for the Corporation through the payment of: (i) annually- guaranteed minimum payments in predetermined amounts, (ii) fees calculated as specified percentages of their respective gross revenues, if any, to the extent such fees are in excess of annually-guaranteed minimum payments, and (iii) in some cases, monthly rents per square footage of leased storage space. The Corporation has stated that the primary concession provider for the restaurant, gift shop, and cafe within the Terminal Building is scheduled for renewal in October 2017. Because it is expected that the Terminal Expansion Project will necessitate the temporary relocation of concessionaires, the Corporation and such concessionaire are currently negotiating a temporary concessionaire agreement which is expected to result, on a temporary basis, in a smaller footprint DMWEST#16594819 v6 43 of available concession offerings during the Terminal Expansion Project period. As a result, concession revenues may decrease from current levels until the completion of the Terminal Expansion Project and the selection of a new permanent concession provider. The Terminal Expansion Project is expected to allow for consolidation and improved location of concessions in upon completion of the construction, with the goal of increasing concession revenues in the future. However, there is no guarantee that such increased revenues will be realized. See"THE PROJECT—Terminal Expansion Project." Parking Facilities Sublease The Corporation and the County entered into a Parking Facilities Sublease dated as of June 1, 2001, as amended (the "Parking Facilities Sublease") pursuant to which the County subleases from the Corporation a portion of the existing public parking area (the "Subleased Parking Area") for the Terminal Building. Under the Parking Facilities Sublease, the County is given the nonexclusive right to operate parking facilities at the Subleased Parking Area, including the right to charge for parking. The County has the right to renew the Parking Facilities Sublease for successive annual terms through December 31, 2045. Notwithstanding the foregoing, the Parking Facilities Sublease terminates upon the defeasance of Bonds issued under the Indenture to finance the Terminal Building Project (including the Terminal Building Expansion)and any Bonds issued to refund the same. The County's decision to renew annually the Parking Facilities Sublease is to be determined by whether or not the County Board has, on or before December 31 of each year, (a) specifically included the rentals under the Parking Facilities Sublease in the County's annual budget, or(b) if no rentals are expected by the Corporation to be due for the upcoming year, the County did not provide written notice to the Corporation of the County's intent not to renew. See "CERTAIN INVESTMENT CONSIDERATIONS—Parking Facilities Sublease, De-Icing Facility Sublease and Road Improvements Lease; Annual Appropriation Risk." The County has renewed the Parking Facilities Sublease each year in accordance with it terms. Under the Parking Facilities Sublease, the County agrees to pay, on April 15 of each year the Parking Facilities Sublease is in effect an annual sum of$10.00 which is to be increased in any year, up to the Space and Facilities Charges Cap Amount applicable in that year, by (a) the amount of Project Revenues required to be deposited in the Capital Fund in order to maintain the Minimum Capital Fund Balance as of April 1 of such year, as determined by the Corporation, and(b) the amount required as of April 1 of such year for the ratio of(x) Net Revenues for such year (excluding any Excess PFC Revenue for such year), together with Other Available Funds and investment earnings on the Debt Service Reserve Fund, to (y) the estimated Debt Service on the Bonds to be 1:1. The Parking Facilities Sublease defines "Space and Facilities Charges Cap Amount" as an amount equal to $411,000 commencing with the Fiscal Year ending December 31, 2017, as adjusted each year starting with the Fiscal Year ending December 31, 2018 by the Denver-Aurora-Lakewood, Colorado Consumer Price Index for all Urban Consumers,All Items,published by the U.S. Bureau of Labor Statistics. DMWEST#16594819 v6 44 De-Icing Facility Sublease The Corporation and the County entered into a De-Icing Facility Sublease dated as of June 1, 2006, as amended (as previously defined, the "De-Icing Facility Sublease") pursuant to which the County subleases from the Corporation the land and leases the de-icing facility improvements constructed on the land. Under the De-Icing Facility Sublease, the County is given the nonexclusive right to operate the de-icing facility, including the right to charge for services provided by the facility. The County has a right to renew the De-Icing Facility Sublease for successive annual terms through December 31, 2031. Notwithstanding the foregoing, the De- Icing Facility Sublease terminates upon the defeasance of the Series 2017A Bonds and any Bonds issued to refund the Series 2017A Bonds. The County's decision to renew annually is to be determined by whether or not (a) the County Board has, on or before December 31 of each year, specifically included the rentals under the De-Icing Facility Sublease in the County's annual budget or, (b) if no rentals are expected by the Corporation to be due for the upcoming year, the County did not provide written notice to the Corporation of the County's intent not to renew. See "CERTAIN INVESTMENT CONSIDERATIONS—Parking Facilities Sublease, De-Icing Facility Sublease and Road Improvements Lease; Annual Appropriation Risk." Since its execution, the County has renewed the De-Icing Facility Sublease each year in accordance with it terms. Under the De-Icing Facility Sublease, the County agrees to pay, on April 15 and October 15 of each year the De-Icing Facility Sublease is in effect, the sum equal, in the aggregate, to the current annual Debt Service on the Series 2017A Bonds, subject to a reduction equal to (i) with respect to the April 15th payment, an amount on deposit in the Principal Account and the Interest Account which, as determined by the Corporation, is available to pay principal and interest on the Series 2017A Bonds due on May 1 of such year, and (ii) with respect to the October 15th payment, an amount on deposit in the Interest Account which, as determined by the Corporation, is available to pay interest on the Series 2017A Bonds due on November 1 of such year. The revenues generated by the operation of a de-icing facility by the County are not pledged to the repayment of the Bonds. However, the County has been transferring each year to the Corporation for application to the Revenue Fund certain amounts received by the County pursuant to an agreement between the County and Vail Valley Jet Center, LLC ("VVJC") in connection with VVJC's use of a portion of the De-Icing Facility. See Table 2 under "FINANCIAL OPERATIONS—Historical Financial Operations" for such amounts transferred by the County to the Corporation. That agreement terminated in February of 2017. Although it is expected that VVJC will need to use the de-icing facility in the future, neither VVJC nor the County has commenced any negotiations with respect to any agreement regarding such future use. Furthermore, the County is not obligated to transfer any amounts received by it from VVJC or any other users of the de-icing facility and, therefore, such amounts may not be available to the Corporation in the future. Road Improvements Lease The Corporation and the County entered into the Road Improvements Lease, pursuant to which the County leases the Road Improvement Site for purposes of making various road DMWEST#16594819 v6 45 improvements in connection with the realignment of Airport access roads and operating such improvements during the lease term. The County has the right to renew the Road Improvements Lease for successive annual terms through December 31, 2031. Notwithstanding the foregoing, the Road Improvements Lease terminates upon the defeasance of the Series 2017A Bonds and any Bonds issued to refund the Series 2017A Bonds. The County's decision to renew annually is to be determined by whether or not (a) the County Board has, on or before December 31 of each year, specifically included the rentals under the Road Improvements Lease in the County's annual budget or, (b) if no rentals are expected by the Corporation to be due for the upcoming year, the County did not provide written notice to the Corporation of the County's intent not to renew. See "CERTAIN INVESTMENT CONSIDERATIONS—Parking Facilities Sublease, De-Icing Facility Sublease and Road Improvements Lease; Annual Appropriation Risk." Since its execution, the County has renewed the Road Improvements Lease each year in accordance with it terms. Under the Road Improvements Lease, the County agrees to pay, on April 15 and October 15 of each year, the Road Improvements Lease is in effect, the sum equal, in the aggregate, to the current annual Debt Service on the Series 2017A Bonds, subject to a reduction equal to (i) with respect to the April 15th payment, an amount on deposit in the Principal Account and the Interest Account which, as determined by the Corporation, is available to pay principal and interest on the Series 2017A Bonds due on May 1 of such year, and (ii) with respect to the October 15th payment, an amount on deposit in the Interest Account which, as determined by the Corporation, is available to pay interest on the Series 2017A Bonds due on November 1 of such year, and subject to a further reduction in the amount equal to the amount of payments made by the County to the Corporation under the De-Icing Facility Sublease on April 15 or October 15, as applicable. The revenues generated by the operation of road improvements by the County are not pledged to the repayment of the Bonds.

THE PROJECT Terminal Building Project and the Terminal Expansion Project The Terminal Building, together with access road improvements and non-revenue public parking areas comprise the Terminal Building Project. The current Terminal Building is an approximately 91,000 square foot scheduled commercial passenger terminal which includes six gate locations, thirteen ticket counters (each counter is a two-position counter) in the ticketing lobby; airline ticket operations offices behind the thirteen ticket counters; an outbound baggage conveyor system for all airline ticket counters and curbside check-in ticket counters; six ticket counters located outside the terminal at the curbside check-in area; three `T'-shaped baggage conveyors, and one oversized baggage slide, all located in the baggage claim area; restrooms, passenger hold rooms, airline operations space, and concession space. The Corporation believes that the Terminal Expansion Project is necessary in order to address known deficient areas within the Terminal Building, such as curbside/check-in operational concerns, TSA screening checkpoint passenger flow concerns, and departure lounge and baggage claim issues. The Corporation expects that the Terminal Expansion Project would enhance the customer experience with a larger circulation area and updated amenities, provide flexibility for terminal operations with shared use gates, and increase the level of safety and efficiency with the addition of four passenger boarding bridges (PBBs). The Terminal Expansion Project will involve the re-design, replacement and expansion of the entire hold room portion of the existing Terminal Building which currently contains six gate locations. Upon completion, such area is planned to consist of two levels containing approximately six gates, passenger holding rooms, restrooms, two escalators, one elevator, and core shell space for future concessionaire spaces (which will ultimately be built out by such concessionaires), support services, and a redesigned TSA checkpoint that will increase queuing space. Gates One through Four will be located on the second floor and will be served by PBBs and Gates Five and Six will be located on the first floor and will be ground boarding gates. The Terminal Expansion Project is expected to add approximately 50,000 square feet to the current Terminal Building, resulting in approximately 141,000 square foot Terminal Building upon completion of the Terminal Expansion Project. DMWEST#16594819 v6 47 During the Terminal Expansion Project, four temporary gates and a food concessions area will be located in or near"Terminal B" (possibly with the addition of a temporary structure during construction) and a minimum of two gates will be utilized in the existing Terminal Building while the other four gates are being constructed. Terminal B is located adjacent to the Vail Valley Jet Center approximately 500 ft. to the east of the Terminal Building and will be connected to the Terminal Building with a temporary corridor. These temporary facilities will allow for full passenger terminal operations while the Terminal Expansion Project is being completed. The Terminal Expansion Project was designed and will be built by the Design-Builder pursuant to the DB Contract, which is described in more detail under "—Design-Build Contract for the Terminal Expansion Project; Consulting Engineer"below. The Terminal Building Project is owned by the Corporation and is located on the Terminal Building Site which is owned by the County and leased to the Corporation pursuant to the terms of the Terminal Ground Lease, described in "—The Ground Leases" below. The Terminal Expansion Project will also be owned by the Corporation and will be located on the Terminal Building Site. Pursuant to the terms of the Project Construction and Management Agreement dated as of , 2017 and a predecessor agreement (collectively, the "Terminal Building Management Agreement"), the County operates the Terminal Building Project on behalf of the Corporation. 2006 Project The 2006 Project consisted of(i) construction of an aircraft de-icing facility comprised of a surface area of 122,000 square feet, two concrete pads, and two underground containment systems and related improvements, and (ii) construction and realignment of access roads to the Airport by re-routing the western end of Eldon Wilson Road to intersect Cooley Mesa Road with Spring Creek Road and the acquisition of an adjacent approximately 2.0-acre property in connection with the road realignment. The de-icing facility and the Road Improvement Site are owned by the Corporation. The de-icing facility is located on the De-Icing Facility Site that is leased by the Corporation from the County under the De-Icing Facility Ground Lease. The De-Icing Facility Site and the improvements constructed thereon are subleased by the Corporation to the County under the De- Icing Facility Sublease. The Road Improvement Site is leased by the Corporation to the County under the Road Improvements Lease. The remaining portion of the road improvements is located on the land owned by the County but is leased to the Corporation. The County operates the de- icing facility pursuant to the De-Icing Facility Sublease and all road improvements pursuant to the Road Improvements Lease. See "AIRPORT AGREEMENTS— De-Icing Facility Sublease;—Road Improvements Lease." The Design-Build Contract for the Terminal Expansion Project; Consulting Engineer The Corporation entered into a design-build agreement (as previously defined, the "DB Contract") with Hensel Phelps Construction Co., a Delaware general partnership (as previously defined, the "Design-Builder") for the design and construction of the Terminal Expansion DMWEST#16594819 v6 48 Project. The DB Contract sets a guaranteed maximum price of $29,145,837. The current construction budget includes an additional approximately $3,855,000 to be paid by the Corporation directly for various costs related to the Terminal Expansion Project, such as costs related to building permits fees, passenger boarding bridges, temporary facilities and contingency, which brings the total estimated costs of the Terminal Expansion Project to approximately$33,000,000. The Design-Builder agrees to construct the Terminal Expansion Project based on the schedule which provides for milestone dates by which substantial completion of each phase of construction must be achieved. The DB Contract provides that substantial completion of all work under the DB Contract must occur on November 15, 2019 (the "Substantial Completion Date"). If such milestones and the Substantial Completion Date are not achieved, the DB Contracts requires the Design-Builder to pay liquidated damages for each day of delay up to a maximum aggregate limit of$750,000. Hensel Phelps Construction Co. is one of the largest general contractors and construction managers in the United States, ranked consistently among ENR's (Engineering News-Record) top 20 Contractors. Founded in 1937 by a small, local builder in Greeley, Colorado, Hensel Phelps has grown into a multibillion-dollar employee owned, national contractor. The Hensel Phelps team has delivered over 190 aviation projects with a combined value exceeding $6 Billion. Hensel Phelps provides extensive experience coordinating with airport operations and airlines facilities personnel throughout the United States, including the successful delivery of projects at many major airports, such as Baltimore—Washington International Airport, Dallas/Fort Worth International Airport, Washington Dulles International Airport, George Bush Intercontinental Airport, Los Angeles International Airport, Orlando International Airport, San Francisco International Airport and San Jose International Airport. Hensel Phelps has worked on a variety of aviation project types for the Federal Aviation Authority (FAA), local and regional aviation authorities, the Department of Defense, as well as private airlines. This past experience will allow Hensel Phelps to be the expert in planning and site logistics as well as coordination and phasing activities while working in the fully operational airport. The Corporation retained Menendez Architects pc as the consulting engineer for the Terminal Expansion Project (the "Consulting Engineer"). Menendez Architects pc is a full service architectural firm based in Aspen, Colorado, with over 33 years of experience in the design of public, commercial, industrial and residential projects. Menendez Architects was involved as the architect of record on five Eagle County Regional Airport Projects and dozens of Eagle County Projects, including the TSA Security Checkpoint and Office Remodel in the existing Terminal and new Snow Removal Equipment Facility. In accordance with the requirements of the Indenture, the Corporation will collaterally assign to the Trustee all of its rights, title and interest in and to the DB Contract, all contracts entered into by the Corporation in connection with the performance of the work or the supply of the materials required for the construction of the Terminal Expansion Project, all guarantees and other undertakings covering the quality or performance of the work or the quality of the materials required by the Construction Contract, contracts and subcontracts, all building permits, governmental permits, governmental approvals, licenses, and authorizations issued in connection with the construction, development or operation of the Terminal Expansion Project; and all DMWEST#16594819 v6 49 plans, specifications and other information related to the design or construction of the Terminal Expansion Project prepared by the Corporation, Design-Builder, any other contractor or subcontractor and any other person involved in the design or construction of the Terminal Expansion Project. The Trustee is to have the right (but not the obligation) at any time to cure any default under the foregoing documents collaterally assigned to it or to protect the rights of the Corporation or the Trustee under such documents. The Design-Builder has consented to such collateral assignment of the DB Contract and has agreed that upon receipt of a written notice from the Trustee that that the Corporation is in default under the Indenture or the Deed of Trust, the Design-Builder shall continue performance on behalf of the Trustee under the DB Contract according to its terms. Similarly to the assignment of the DB Contract, the Corporation will also assign all of its rights under the contract with the Consulting Engineer to the Trustee and the Consulting Engineer will consent to such assignment and will agree that upon receipt of a written notice from the Trustee that that the Corporation is in default under the Indenture or the Deed of Trust, the Consulting Engineer shall continue performance on behalf of the Trustee under the Consulting Engineer Contract according to its terms. Ground Leases The Terminal Building Site on which the Terminal Building Project is located (and on which the Terminal Expansion Project will be located) is owned by the County and leased by the County to the Corporation pursuant to the Second Restated Ground Lease dated December 16, 1996, as supplemented and amended (as previously defined, the "Terminal Building Ground Lease"). The De-Icing Facility Site on which the de-icing facility is located is also owned by the County and leased by the County to the Corporation pursuant to the Ground Lease dated as of June 1, 2006, as supplemented and amended (as previously defined, the "De-Icing Facility Ground Lease" and together with the Terminal Building Ground Lease, the "Ground Leases"). The Terminal Building Ground Lease expires on December 31, 2045, but is required to be terminated earlier in the event the Bonds which financed or refinanced the Terminal Building Project (including the Terminal Building Expansion)have been defeased. The De-Icing Facility Ground Lease expires on December 31, 2031, but is required to be terminated earlier upon defeasance of the Series 2017A Bonds and any Bonds issued to refund the Series 2017A Bonds. Under the original Ground Leases,the Corporation was required to pay to the County annual rent payable in equal monthly installments. In connection with the issuance of the Series 2017 Bonds, each Ground Lease will be amended to provide that the rent will be payable once a year, in May of each year, but not sooner than May 2, after (i) all principal and interest payments due on the Bonds then outstanding under the Indenture have been paid in full on the immediately preceding May 1, (ii) all deposits into the Debt Service Reserve Fund required by the Indenture have been made and(iii) the Capital Fund is funded in the amount of the Minimum Capital Fund Balance. If any requirements set forth in clauses (i) through (iii) above are not met, the amendments to the Ground Leases will provide that the rent is to be deferred until the next following month in which each of such requirements are met and that such deferred amount shall not accrue any interest.

DMWEST#16594819 v6 55 Legal Matters Affecting the County Litigation. [According to the County Attorney, the County is not subject to any pending or threatened litigation which would materially, adversely affect the County's operations or financial condition. [Confirm before posting] Sovereign Immunity. The Colorado Governmental Immunity Act, Sections 24-10-101 et seq., Colorado Revised Statutes, as amended(the"Immunity Act"),provides, in part,that public entities are immune from liability in all claims for injury which lie in tort or could lie in tort (regardless of the type of action or the form of relief chosen by the claimant), except to the extent specifically excluded by the Immunity Act. These exclusions include claims resulting from: (a) the operation, by a public employee during the course of his or her employment, of a motor vehicle (other than certain emergency vehicles) which is owned or leased by a public entity; (b) the operation by a public entity of a public hospital, correctional facility or jail; (c) a dangerous condition of any public building; (d) a dangerous condition that impedes traffic on a public highway, road or street, a dangerous condition caused by a failure to realign traffic signs turned to reassign the right-of-way or by a failure to repair traffic lights displaying conflicting directions, or a dangerous condition caused by a known accumulation of snow and ice which interferes with access to public buildings; (e) a dangerous condition of any public hospital,jail, public facility located in any park or recreation area maintained by a public entity, or public water, gas, sanitation, electrical, power, or swimming facility; (f) the operation and maintenance by a public entity of any public water, gas, sanitation, electrical, power or swimming facility; (g) the operation and maintenance of a qualified state capital asset that is the subject of a leveraged leasing agreement or (h) failure to perform an education employment required background check. The maximum amount that may be recovered on a claim based on a single occurrence involving one of the exclusions of the Immunity Act is limited to $350,000 for injury to one person and$990,000 for injury to two or more persons in a single occurrence. The Immunity Act also provides that public entities are not liable either directly or by indemnification for punitive or exemplary damages or for damages for outrageous conduct, except where the public entity determines by resolution that it is in the public interest to defend or settle a claim for punitive damages against a public employee. The County, however, may not be immune from liability and may be subject to liability in excess of the maximum limits established by the Immunity Act in the event of claims based on certain federal laws or state laws not grounded in tort, for example: suits filed pursuant to 42 U.S.C. § 1983 alleging the deprivation of federal constitutional or statutory rights of an individual, suits alleging anti-competitive practices and violation of the anti-trust laws by the County in the exercise of its delegated powers and suits based on breach of contract. The Immunity Act also specifies the sources from which judgments against public entities may be collected. Pursuant to the Immunity Act, a public entity may prospectively waive its immunity. The County has not waived its immunity and has no plans to do so. The Immunity Act may be amended by the State General Assembly at any time. Aside from liability for certain tortious actions, as described above, the County may also be subject to civil liability for actions under various federal or State laws. Examples of potential federal civil liability include suits filed pursuant to 42 U.S.C. § 1983 alleging the deprivation of federal constitutional or statutory rights of an individual, and suits alleging anti-competitive practices and violation of antitrust laws except in the exercise of its delegated powers. Examples of potential civil liability under State laws include actions related to contractual obligations, such DMWEST#16594819 v6 56 as employment contracts, capital construction contracts and lease contracts, and actions alleging inverse condemnation. THE AIRPORT Airport Facilities General. The Airport is a publicly owned and used airport located in northwest Colorado between the towns of Eagle and Gypsum, approximately 35 and 25 miles, respectively, from the Vail and Beaver Creek Resorts/Ski Areas. The present Airport site encompasses approximately 650 acres, and includes one 9,000- foot runway that is 150 feet in width. The runway pavement section consists of 12 inches of asphalt on six inches of aggregate base course. The pavement section is rated at greater than 75,000 pounds for aircraft with single wheel gear and 255,000 pounds for aircraft with dual tandem wheel gear. The runway is painted with precision instrument runway markings. Taxiway "A" is a 75-foot-wide full-length taxiway parallel to and south of the runway and is paved with asphalt. In 1996, the Corporation undertook the construction and equipping of the Terminal Building as well as the construction of parking areas, access road improvements, and sewer and other utility improvements. The Terminal Building was expanded in 2001 and in 2007 and will be further expanded and renovated as part of the Terminal Expansion Project. See "THE PROJECT—The Terminal Building Project and the Terminal Expansion Project." Outside of the Terminal Building, the Airport currently has two separate aircraft parking aprons. The concrete air carrier and general aviation parking apron for Terminal A and the FBO Terminal is located on the south side of the runway and is approximately 110,000 square yards in size. There are air carrier parking spaces for a total of 10 Boeing 757 aircraft. There is an additional general aviation apron north of the runway and adjacent to a closed runway which now serves as Taxiway `B." The north apron contains approximately 32,915 square yards of paved aircraft parking space. There are 13 tie-down positions marked on the north apron that are used to tie down aircrafts. The runway is equipped with a High Intensity Runway Lighting system, including Precision Approach Path Indicator Lights and Runway End Identifier Lights. There is a rotating beacon to assist pilots in locating the Airport at night and during periods of inclement weather. The Airport has an air traffic control tower to assist pilots in making landings and takeoffs. A Category I Instrument Landing System is installed on Runway 25, which has increased the aircraft arrival capacity and reliability of the Airport during periods of adverse/low-visibility weather. A BI-6 radar system was commissioned in summer 2007 and has further increased arrival and departure capacity during all periods at the Airport. The 1,000-foot runway extension project, completed in 2009, has enhanced safety at the Airport and increased payload capacity for departing aircraft. The Terminal Building and the FBO Terminal (described in "—General Aviation Services" below) are located on the south side of the runway. In addition to these facilities, there are large executive hangars, a fuel truck storage area, a de-icing facility and an underground fuel DMWEST#16594819 v6 57 farm on the south side. An electrical vault and telephone equipment room are located just south of the vehicular parking lot. The north apron area includes the following facilities: air traffic control tower; ceilometer; an Automated Weather Observation System; the Colorado Army National Guard Colorado High Altitude Training Site Headquarters; seven executive hangars; and an Airport maintenance shop and storage area. In 1992, the County constructed an approximately 12,000-square-foot air rescue and fire- fighting and snow removal equipment building ("ARFF/SRE"). The ARFF/SRE building contains six bays, an apparatus storage area, maintenance and parts repair areas, a day/training room and a watch alarm room. This facility is located on the south side of the runway, near the Terminal Building Project Site. In the last five years, approximately $35,000,000 in capital improvements have been made to the Airport facilities, with most improvements funded with federal AIP grants to the Airport. These improvements are shown in the table below. Year Project Amount 2012 Air Carrier Apron Construction $1,894,737 (Phase I) Air Carrier Apron Construction 391,813 (Phase I) 2013 Snow Removal Equipment 1,988,364 Facility Snow Removal Equipment 3,011,636 Facility 2014 Air Carrier Apron Construction 8,858,000 (Phase II) CDOT Runway/Taxiway 515,000 Pavement Maintenance Project 2015 Air Carrier Apron Construction 7,699,181 (Phase III)(AIP 55) 2015 North GA Area Infrastructure 500,000 (Phase I) 2016 Air Carrier Apron Construction 9,569,610 (Phase IV)(Design and 2017 Construction)(AIP 56) DMWEST#16594819 v6 58 The area west of the north apron and surrounding Taxiway `B" has been leased to the Colorado Army National Guard for future expansion of the Colorado High Altitude Training Site. Two access roads provide entry into the Airport. One is located north of the Airport and links the general aviation apron to U.S. Highway 6. The other is located south of the Airport and links the commercial aircraft apron, including the Terminal via Cooley Mesa Road to U.S. Highway 6. This road provides access to the Terminal Building Project and in 2007 was aligned to intersect with Spring Valley Road, at its Cooley Mesa road intersection. Interstate 70, approximately 3/4 of a mile north of the Airport, is accessible to the west via the U.S. 6 connector through the Towns of Eagle and Gypsum. The Airport has one underground fuel farm located on the south side of the Airport at the FBO Terminal and one above-ground fuel farm located on the north side of the Airport. The underground fuel farm consists of one 5,000 gallon defuel tank, two 40,000 gallon, two 30,000 gallon and two 20,000 gallon jet fuel tanks. There is also an underground 10,000 gallon lead-free vehicle fuel tank. The above-ground fuel farm on the north side consists of a 12,000 gallon jet fuel tank and a 12,000 gallon 100LL avgas tank. All utility lines serving the Airport are buried underground and provide service to the buildings and airfield facilities. All utilities can be extended to accommodate the Project. Potable water and water for fire protection are provided to the Airport by the Town of Gypsum. Electricity is provided by Holy Cross Electric and natural gas is provided by Black Hills Energy. The Airport's telephone service is provided by CenturyLink. Trash and refuse are collected and hauled to the County landfill which is approximately 13 miles east of the Airport. Wastewater treatment for Airport facilities is provided by the Town of Gypsum. General Aviation Services. Vail Valley Jet Center, LLC (as previously defined, "VVJC"), located at the facility commonly referred to as the FBO Terminal, operates at the Airport a fixed-base service providing general aviation users, facilities and operations pursuant to an Amended and Restated Fixed Base Operator Concession Agreement and Lease dated as of September 29, 2009 (as amended and supplemented, the "FBO Lease"). The initial term of the FBO Lease expires on December 31, 2039, with an option exercisable by VVJC to renew the FBO Lease for an additional 10 years. Pursuant to the FBO Lease, VVJC (a) provides certain aircraft line services, aircraft airframe and engine repair and maintenance services, charter services, aircraft rental and flight instruction services, and (b) leases at the Airport from the County certain property on which a general aviation terminal, hangars and fuel farm is located. Payments under the FBO Lease are not pledged to the payment of the Bonds. Airport Management Airport operations are accounted for in an enterprise fund of the County and the Airport is currently managed by the County Manager under the supervision of the County Board. See "—County Government and Management" above under this caption. The County recently hired a new Director of Aviation, Kip Turner, which will manage the Airport under the supervision of the County Manager and the County Board. DMWEST#16594819 v6 59 Budget Process. The Airport's budget is prepared on the basis of modified accrual accounting. As a fully integrated fund of the County, the Airport budget is prepared by the Director of Aviation (or in the absence of the Director of Aviation, the County Manager) and other employees of the County, and then submitted to the County and incorporated into its budget as one of the County's enterprise funds. Accordingly,the Airport budget is subject to the budgeting requirements of the State, and the related budget hearings and open public meeting requirements of the County's budget process. The budget is ultimately approved by the County Board. The County Board approved the Airport's operating budget for 2017 in December of 2016. Airport Insurance. The County maintains property and general liability insurance. The Airport maintains a comprehensive general liability insurance policy purchased through AON Risk Services Central, Inc. with, among other coverages, an aggregate products/completed operations limit of $100,000,000, an aggregate personal and advertising injury limit of $50,000,000 and a limit per occurrence of $100,000,000. In addition, the County maintains construction and builder's risk insurance for certain capital projects at the Airport. Service Area The Airport serves the County and surrounding areas, including Summit County,Garfield County, Pitkin County, Routt County, and the communities of Arrowhead, Avon, Beaver Creek, Eagle, Eagle-Vail, Edwards, and Vail. Commercial service at the Airport, however, serves primarily destination passengers visiting the Vail, Arrowhead and Beaver Creek resorts, as well as the ski and resort areas at Aspen, Buttermilk, Snowmass, Copper Mountain, Arapahoe Basin, Keystone,Breckenridge and Ski Sunlight. As of December 31, 2016, the County had an estimated permanent resident population of 53,989 representing approximately a 1.2% increase from the County's population of 53,346 in 2015. The County's economy is heavily dependent on the tourism industry, which is based in great part on skiing and resort-based activities. For additional information relating to the County and the skiing and resort activities located therein, which is the primary area within the service area of the Airport, see "APPENDIX B—ECONOMIC AND DEMOGRAPHIC INFORMATION REGARDING EAGLE COUNTY." Airport Master Plan and Capital Improvements Effecting Terminal Building The County and the Corporation approved an updated Airport Master Plan in 2014 which outlines a twenty year capital improvement program (from 2013 through 2032) for both the Airport and the Terminal Building Project and other facilities and improvements financed by the Corporation based on existing facilities, aviation activity forecasts, sustainability, and identified future needs on all areas of the airport including terminal, airfield, and landside areas. The Airport Master Plan was prepared by Jviation, a planning, design, and construction administration firm headquartered in Denver, Colorado. Airport Master Plans are typically updated every seven to ten years, or longer, based on the then current needs. The capital improvement plans are prepared annually taking into account the Airport Master Plan. DMWEST#16594819 v6 60 Capital Improvements Effecting Terminal Building. The Airport Master Plan anticipates $71,000,000 (in 2013 dollars) and $91,000,000 (adjusted for 3% inflation every year starting in 2014) in capital improvements costs for the period from 2013 through 2032. The Airport Master Plan divides such capital improvements into three planning periods as described below. Capital improvements anticipated to be completed during the short term period (2013- 2017) include terminal interior renovation projects, certain road improvements projects, the Terminal Expansion Project and the passenger boarding bridges to be funded with a combination of available cash, revenue bonds and private third party financing for a total of approximately $34,500,000 (as adjusted for inflation). Other than the Terminal Expansion Project and PBBs, the Corporation does not anticipate completing other projects identified in the Airport Master Plan for the 2013-2017 period. Capital improvements included in the Airport Master Plan for the intermediate term period (2018-2022) and long-term period (2023-2032) include various road and parking improvements and further expansion of the Terminal Building. The Corporation has not recently evaluated the timing, costs or funding sources of any of the projects included in the intermediate and long term ranges of the Airport Master Plan. FINANCIAL INFORMATION General The Corporation maintains its financial records on a calendar year basis,using the accrual method of accounting. Financial statements are audited annually by a firm of independent auditors. Financial statements for the Fiscal Years ended December 31, 2016 and 2015 are included in this Official Statement as set forth in APPENDIX C. See also "INDEPENDENT AUDITORS."

DMWEST#16594819 v6 62 Historical Debt Service Coverage Set forth in the following table is a calculation of debt service coverage of the outstanding bonds for Fiscal Years 2012 through 2016 and the budgeted debt service coverage for Fiscal Year 2017. No representation, warranty or other assurance is made or given that historical debt service coverage levels will be experienced in the future. The debt service for the Bonds in Table 3 below for Fiscal Years 2012- 2016 has not been adjusted to take into account the expected refunding of the Series 2006B Bonds with a portion of the proceeds of the Series 2017 Bonds and other legally available moneys.

"Other Available Funds," as defined in the Original Indenture, include minimum Capital Fund balance of$346,819 and PFC Revenue not needed for debt service and directed by the Corporation to be reserved by the Trustee in the PFC Account as Other Available Funds. For purposes of this table,only minimum Capital Fund balance of$346,819 is included as Other Available Funds. Management Discussion of Financial Information During the period from January 1, 2012 to December 31, 2016, the Corporation has experienced continued growth in both total operating revenue and operating net income. In addition, cash held with the Trustee has also increased. Not including the income received for the Terminal Building's in-line baggage system as a grant from the TSA in 2012, net income increased 24% for the period from 2012 through 2016. PFC receipts have been consistent over the same time period. As cash balances and interest rates have increased, investment income has improved 70% from 2012 to 2016. All scheduled debt service payments of the Corporation have been made on time. DMWEST#16594819 v6 63 The growth in net income from $1,533,236 (adjusted, net of TSA grant funds) in 2012 to $2,008,067 in 2016 has resulted in increases in retained earnings in each of the five years from 2012 through 2016. Retained earnings grew from $13,010,373 on January 1, 2012 to $24,155,169 on December 31, 2016. PFC Revenue has remained steady ranging from a low of $501,399 in 2012 to a high of$554,929 in 2016. Cash with the Trustee was $10,550,129 as of December 31, 2016. During the five-year period debt service coverage ratio has ranged from a low of 1.92 in 2015 to a high of 2.22 in 2016 (excluding Other Available Funds), with coverage for 2017 estimated at 2.47 (excluding Other Available Funds). For the six months ended June 30, 2017, the total operating revenue for the Corporation was $2,988,902 a decrease of 4% in the total operating revenues from the same period in 2016 ($3,115,579). Net operating income for the Corporation also decreased 8.4% from $1,369,290 to $1,254,056 for the six months ended June 30, 2016 and 2017, respectively. These decreases were due to reductions in concession and facility charge revenues as a result of lower passenger traffic attributed to unfavorable weather and snow conditions in nearby resorts. The De-Icing facility agreement for cost sharing with VVJC also ended in February 2017, thus reducing income. These numbers are preliminary and unaudited and are based on the conservative estimate by the Corporation of revenues for the six month period in 2017. Airport Operations General. Commercial aviation activity (including charter and scheduled airline activity) at the Airport reaches its highest volumes from approximately December 1st through April 15th of each year and then reaches its second-highest volumes from approximately June 1st through September 15th of each year. In calendar year 2016, enplanements at the Airport totaled 164,671, and three (3) major national air carriers (American Airlines, Delta Air Lines, and United Airlines) and one (1) international carrier (Air Canada) provided scheduled service to the Airport. American Airlines comprised approximately 59% of the volume of scheduled service to the Airport over calendar year 2016. During the winter season between December 1st and April 15th of each year (the peak season for skiing), the Airport generally receives approximately 81% of its enplanements for the year. During that time, the Airport provides direct service to 12 markets with 13 to 15 daily flights using a mix of CRJ (regional jet), 737, A-319, and 757 aircrafts. During the "off season" from late April to early June of each year, United Airlines provides one daily direct flight to Denver, and the other Signatory Airlines provide no service. During the summer and fall months of June through November, United Airlines offers daily non-stop service to Denver and service to Houston twice weekly from July 2nd to September 3rd, and American Airlines offer daily non-stop service to Dallas/Fort Worth. The Airport has experienced an overall increase in summer traffic in recent years and it is expected that this trend will continue over time. However, it is expected that leisure visitors in the winter season will continue to be the primary source of air service and revenue. Historical Passenger Traffic and Airport Operations. The total number of enplaned passengers at the Airport ranged from approximately 168,338 to 170,718 between Fiscal Years 2012 and 2016. Enplanements totaled 107,957 from January 1, 2017 through April 30, 2017 compared to 114,690 for the same period in 2016, predominantly due to flight cancellations DMWEST#16594819 v6 64 nearly doubling during this period of 2017 (72 flight cancellations) as compared to the same period of 2016 (33 flight cancellations). In addition, the month of April 2016 had one (1) additional day of commercial flight activity than April 2017 did,which resulted in a difference of 11 fewer flight departures. Set forth below is a table showing scheduled airline enplaned passenger and aircraft departure information since 2012. TABLE 4 Eagle County Regional Airport Historical Scheduled Airline Passenger Traffic 2012-2017 Scheduled Airline Scheduled Airline Enplaned Passengers Aircraft Departures Percent Year Number Increase/Decrease Number 2012 168,338 -- 1,954 2013 167,490 -0.51% 1,960 2014 164,915 -1.56 2,026 2015 162,321 -4.11 1,914 2016 170,718 5.17 1,939 2016' 114,677 -- 1,217 2017' 110,024 -5.87 1,175 'Through April 30. Source:The Corporation Passenger Origins and Destinations. Since 1989, all of the enplanements at the Airport represented originating and destination passengers. No enplanements represented connecting passengers changing planes at the Airport. For the 2016-17 winter season,the strongest communities of interest in terms of air travel to the Airport (whether as origin or connecting travel) are Miami, Dallas/Fort Worth, New York and New Jersey (John F. Kennedy and Newark airports), Houston, and Los Angeles. The remainder of the top ten origin or connecting areas in terms of number of passengers traveling to and from the Airport are Chicago, Atlanta, and Denver. Non-stop service to Phoenix was added in 2016 and new non-stop service to Salt Lake City and San Francisco will be added for the 2017-2018 winter season. This would total fourteen non-stop direct markets to be served by the Airport in the 2017-2018 winter season, up from twelve non-stop direct flight markets served in the 2016-2017 winter season. Airlines Serving the Airport. In addition to the airlines described above, charter airlines provided service to the Airport on an occasional basis in 2016. The airlines serving the Airport (excluding charter airlines)provided during this period scheduled non-stop service to twelve (12) DMWEST#16594819 v6 65 A cities in the United States,primarily during the peak portions of the winter and summer seasons. During the winter season, there is an average of 13 departures per day during the week, 15 departures on Saturdays and 15 departures on Sundays. The following table presents the market shares of enplaned passengers for the Signatory Airlines serving the Airport for the years ending December 31, 2012 through December 31, 2016, along with information for the first six months of 2017.

Source: The County Terminal Building Concessions The principal concessions of the Terminal Building Project are the rental car services, ground transportation services and retail services, comprised of news, gift, clothing, and food and beverage sales. The Corporation also derives revenues from advertising, telephones and space rentals. Such concessions will generally operate under concession agreements providing for payment to the Corporation of a percentage of gross revenue, as well as rental for leased space. See "AIRPORT AGREEMENTS— Other Terminal Building Revenues" for additional discussion of Terminal Building concessions.

Federal Grants One source of federal grants benefiting the Airport is the FAA's Airport Improvement Program (as previously defined, the "AIP") established pursuant to the Airport and Airway Improvement Act of 1982. The AIP is administered by the FAA and funded by the Airport and Airway Trust Fund (the "Trust Fund"). The Trust Fund is financed by aviation user taxes. Grants are available to airport operators in the form of entitlement funds and discretionary funds. Entitlement funds are apportioned annually based upon enplaned passengers; discretionary funds are available at the discretion of the FAA based upon a national priority system. In June 2017, the Federal Aviation Administration Reauthorization Act of 2017 (S.B. 1405), which proposes to provide funding for the FAA and its programs (including the AlP) through fiscal year 2021, was introduced to Congress, and is expected to be considered prior to the September 30 expiration of the 2016 Reauthorization Act. This bill proposes to increase AIP funding to $3.75 billion for each of fiscal years 2019 through 2021. Additionally, in late July of 2017, the Senate Appropriations Committee approved the fiscal year 2018 annual appropriations bill for the U.S. Department of Transportation, which is expected to be considered sometimes in September of 2017. This bill increases the AIP funding to$3.6 billion. The County has received substantial federal funds through AIP grants in the past for Airport improvement projects. Since 2012, approximately$35,000,000 in federal grants has been received by the County. The proceeds of these federal grants have been used for air carrier apron construction, a Snow Removal Equipment Facility, runway and taxiway maintenance, and general aviation infrastructure at the Airport. It is uncertain whether or at what level such AlP funding will be available in the future. Proceeds from federal grants are not included in the definition of Project Revenues and therefore are not pledged to the payment of the Bonds. DMWEST#16594819 v6 67 REPORT OF THE AIRPORT CONSULTANT The Report of the Airport Consultant prepared in connection with the issuance of the Series 2017 Bonds is attached in APPENDIX A. The Report was undertaken to evaluate the ability of the Corporation to generate sufficient revenues to pay operating expenses, working capital needs, other capital project costs (including the costs of the Terminal Expansion Project) and other financing requirements, including the debt service requirements of the Corporation's proposed issuance of the Series 2017 Bonds along with the debt service requirements of the Corporation's outstanding Series 2011A Bonds. The period of evaluation of the Report is the Corporation's fiscal years ended December 31,2017 through December 31,2023. The Report is based on preliminary estimated information and will not be updated to reflect the final terms of the Series 2017 Bonds. The Report was based on a number of assumptions and contains projections and statements relating to operating and financial results that may not be realized. The assumptions used reflect the best information available to the Corporation and the County and reliance on the knowledge and experience of the Airport Consultant. The Corporation's future operating and financial performance, however, may vary from the projections and such variances may be material. Among other things, the Report assumes (i) airline traffic demand at the Airport will remain level through the end of the projection period of 2023 (see "FINANCIAL INFORMATION—Airport Operations— Historical Passenger Traffic and Airport Operations" and "TABLE 4—Eagle County Regional Airport Historical Scheduled Airline Passenger Traffic 2012-2017"), (ii) all Signatory Airlines will extend and continue to operate under their Terminal Building Leases through the end of the projection period of 2023 on terms and conditions, including rental amounts, that are substantially similar to the current Terminal Building Leases, and (iii) the rental car companies currently serving the Airport will extend their concession agreements with the Corporation through the end of the projection period with agreement provisions, minimum annual guarantees and rental amount requirements that are substantially similar to the current agreements. See "AIRPORT AGREEMENTS—Terminal Building Leases." Regulatory and other restrictions may adversely affect the ability of the Corporation to achieve the projections in the Report. See "CERTAIN INVESTMENT CONSIDERATIONS - Regulations and Restrictions Affecting the Airport." The Report, among other things, includes a projection of the Corporation's debt service coverage ratio (based on a maximum annual debt service on the Bonds)for the period from 2017 through 2023, which is forecast to increase from 1.99x in 2017 to 2.28x in 2023. See APPENDIX A. The calculation of the operations and maintenance expenses exclude annual rent payable under the Ground Leases and the management fees due to the County under the Terminal Building Management Agreement because, pursuant to such agreements, rent and management fees will be payable once a year in each May (not earlier than May 2) after principal and interest payments on the Bonds have been made on the immediately preceding May 1, all required deposits into the Debt Service Reserve Fund have been made and the Capital Fund is funded in the amount of the Minimal Capital Fund Balance. In addition, the calculation of the projected debt service coverage ratio during this period in the Report is based on the assumption that Other Available Funds will not be needed for purposes of calculating Corporation's revenues available to pay Debt Service on the Bonds. The Indenture permits the Corporation to DMWEST#16594819 v6 68 use Other Available Funds to pay the Debt Service and to include Other Available Funds in the calculation of the debt service coverage ratio. Under the Indenture, Other Available Funds is generally an amount determined appropriate by the Corporation to be transferred from the Capital Fund to the Revenue Fund for the foregoing purposes, provided that the Minimum Capital Fund Balance ($346,000) or portion thereof available in the Capital fund, is to be considered as Other Available Funds without the transfer to the Revenue Fund. The Report projects an increase of Other Available Funds during the forecast period, from $7,512,238 in 2017 to $14,290,350 in 2023. See "SECURITY AND SOURCES OF PAYMENT FOR THE SERIES 2017 BONDS—Rate Maintenance Covenant" and APPENDIX C for a more detailed discussion of the debt service coverage ratio calculation. The Report has been included herein in reliance upon the knowledge and experience of Leibowitz & Horton Airport Management Consultants, Inc. as the Airport Consultant. As noted in the Report, any forecast is subject to uncertainties. Therefore, there are likely to be differences between forecast and actual results, and those differences may be material. STATE CONSTITUTIONAL AMENDMENT At the general election held November 3, 1992, the voters of the State approved an amendment (the "Amendment") to the Colorado Constitution limiting the ability of the State and local governments to increase revenues, debt and spending and restricting property taxes, income taxes and other taxes. The Amendment excludes from its restrictions the borrowings and fiscal operations of "enterprises," which term is defined to include government-owned businesses authorized to issue their own revenue bonds and receiving under 10% of their revenues in grants from all State and local governments combined. The County considers the Corporation an "enterprise" within the meaning of the Amendment, with the authority to issue its own bonds payable solely from the Project Revenues. The Project is owned by the Corporation and operated as a self-sustaining business activity. The Corporation is not authorized to levy any taxes. VERIFICATION AGENT Causey Demgen & Moore, Inc., Denver, Colorado will deliver to the Corporation its report indicating that it has examined, in accordance with the standards established by the American Institute of Certified Public Accountants, the mathematical accuracy of the mathematical computations of the adequacy of the deposit of proceeds of the Series 2017A Bonds under the Refunding Agreement to redeem the Refunded Bonds at the redemption price to the redemption date,which is expected to be ,2017. LITIGATION In connection with the issuance of the Series 2017 Bonds, the Corporation will certify that it is not a party to any pending material litigation that would adversely affect its ability to finance or build the Terminal Expansion Project, to own the Project or perform its obligations under the agreements executed in connection with the Project or the Series 2017 Bonds, and that it is not aware of any threats of such litigation. There are no legal proceedings of which the Corporation or the County has received written notice now pending or, to the best of the DMWEST#16594819 v6 69 Corporation's or County's knowledge, threatened which contests or affects any federal grants or PFCs awarded to or held by the County or the Corporation's or County's use of such funds. CONSENT TO THE INDENTURE By purchasing the Series 2017 Bonds, the purchasers thereof are deemed to have consented to the amendment and restatement of the Original Indenture pursuant to the terms of the Indenture as of the date of issuance of the Series 2017 Bonds. The consent of purchasers of the Series 2017 Bonds will be counted in full toward the satisfaction of the requirement contained in the Original Indenture (pursuant to which the Series 2011A Bonds and other prior Bonds of the Corporation were originally issued) that prior written consent of owners of at least 66 2/3% in principal amount of the bonds of the Corporation then outstanding be obtained for amendments to such Original Indenture to come into effect. RATING Moody's Rating Service ("Moody's") has assigned to the Series 2017 Bonds the rating set forth on the cover page of this Official Statement.No other ratings have been applied for. A rating reflects only the views of the rating agency assigning such rating, and an explanation of the significance of, and methodology with respect to, such rating may be obtained from each such rating agency. The Corporation has furnished to Moody's certain information and materials relating to the Series 2017 Bonds, the Corporation, the Airport, and its financial condition and operations, including certain information and materials which have not been included in this Official Statement. Generally, Moody's and other rating agencies base their ratings on such information and materials and on investigations, studies and assumptions by the rating agencies. There is no assurance that Moody's ratings will continue for any given period of time or that such ratings will not be revised downward, suspended or withdrawn entirely by Moody's if, in its judgment, circumstances so warrant. Any such downward revision, suspension or withdrawal of Moody's rating may have an adverse effect on the market price of the Series 2017 Bonds. The Corporation does not undertake any responsibility to oppose any such revision, suspension or withdrawal. UNDERWRITING RBC Capital Markets, LLC has agreed to purchase the Series 2017 Bonds from the Corporation at a purchase price of $ (representing the aggregate principal amount of the Series 2017 Bonds, and less an underwriting discount of $ ). The Underwriter will be obligated to purchase all of the Series 2017 Bonds if any Series 2017 Bonds are purchased. The obligation of the Underwriter to accept delivery of the Series 2017 Bonds is subject to the various conditions of the Bond Purchase Agreement.

TAX MATTERS Federal Law In the opinion of Ballard Spahr LLP, Bond Counsel, under existing law, as presently enacted and construed, interest on the Series 2017 Bonds is excludable from gross income for federal income tax purposes, assuming the accuracy of certifications of the Corporation and the County and assuming continuing compliance by the Corporation and the County with the requirements of the Internal Revenue Code of 1986, as amended (the "Code"), except that interest on any Series 2017 Bond shall not be excluded while held by a substantial user of the facilities financed or refinanced with the Series 2017 Bonds or a related person as provided in the Internal Revenue Code. Interest on the Series 2017 Bonds will be a specific tax preference item for purposes of determining individual and corporate federal alternative minimum tax. Bond Counsel will express no opinion regarding other federal tax consequences of ownership or disposition of, or the accrual or receipt of interest on,the Series 2017 Bonds. The Code establishes requirements that must be complied with subsequent to the issuance of the Series 2017 Bonds for interest thereon to be and remain excludable from gross income pursuant to Section 103 of the Code. Failure to comply with these requirements could cause the interest on the Series 2017 Bonds to be included in gross income, retroactive to the date of issue of the Series 2017 Bonds or at some later date. The requirements include, but are not limited to, (1) the provisions of Section 148 of the Code which prescribes yield and other limits within which the proceeds of the Series 2017 Bonds are to be invested and may require that certain investment earnings on the foregoing be rebated on a periodic basis to the United States, (2) use of the proceeds of the Series 2017 Bonds, and (3) use of the facilities financed with the Series 2017 Bonds. The Corporation and the County have covenanted to comply with the provisions of the Code. Original Issue Discount. The Series 2017 Bonds being offered at a discount ("original issue discount") equal generally to the difference between the public offering price and the principal amount are referred to herein as the "Discount Bonds". For federal income tax purposes, original issue discount on a Discount Bond accrues periodically over the term of such Discount Bond as interest which is excluded from the gross income for federal income tax purposes and subject to alternative minimum tax to the same extent as regular interest. The accrual of original issue discount increases the holder's tax basis in the Series 2017 Bonds for determining taxable gain or loss upon sale or redemption prior to maturity. Holders should consult their tax advisors for an explanation of the accrual rules. Original Issue Premium. The Series 2017 Bonds being offered at a premium ("original issue premium") equal generally to the excess of their public offering price over their principal DMWEST#16594819 v6 71 amount are referred to herein as the "Premium Bonds". For federal income tax purposes, original issue premium is amortizable periodically over the terms of the Premium Bond through reductions in the holder's tax basis for such Premium Bond for determining taxable gain or loss upon sale or redemption prior to maturity. Amortization of premium does not create a deductible expense or loss. Holders should consult their tax advisors for an explanation of the amortization rules. State of Colorado Law To the extent interest on the Series 2017 Bonds is excluded from gross income for federal income tax purposes, such interest is not subject to income taxation by the State of Colorado. No opinion will be expressed regarding other State or local tax consequences arising with respect to the Series 2017 Bonds, including whether interest on the Series 2017 Bonds is exempt from taxation under the laws of any jurisdiction other than the State of Colorado. Changes in Federal and State Tax Law From time to time, there are Presidential proposals, proposals of various federal committees, and legislative proposals in the Congress and in the states that, if enacted, could alter or amend the federal and state tax matters referred to herein or adversely affect the marketability or market value of the Series 2017 Bonds or otherwise prevent holders of the Series 2017 Bonds from realizing the full benefit of the tax exemption of interest on the Series 2017 Bonds. Further, such proposals may impact the marketability or market value of the Series 2017 Bonds simply by being proposed. It cannot be predicted whether or in what form any such proposal might be enacted or whether if enacted it would apply to bonds issued prior to enactment. In addition, regulatory actions are from time to time announced or proposed and litigation is threatened or commenced which, if implemented or concluded in a particular manner, could adversely affect the market value, marketability or tax status of the Series 2017 Bonds. It cannot be predicted whether any such regulatory action will be implemented, how any particular litigation or judicial action will be resolved, or whether the Series 2017 Bonds would be impacted thereby. Purchasers of the Series 2017 Bonds should consult their tax advisors regarding any pending or proposed legislation, regulatory initiatives or litigation. The opinions expressed by Bond Counsel are based upon existing legislation and regulations as interpreted by relevant judicial and regulatory authorities as of the date of issuance and delivery of the Series 2017 Bonds, and Bond Counsel has expressed no opinion as of any date subsequent thereto or with respect to any proposed or pending legislation, regulatory initiatives or litigation. The proposed form of Bond Counsel's approving opinion is attached hereto as Appendix E. LEGAL MATTERS The validity of the Series 2017 Bonds and certain other legal matters are subject to the approving opinion of Ballard Spahr LLP, Denver, Colorado, Bond Counsel to the Corporation.

Source:Colorado Department of Revenue,Calendar Year City and County reports DMWEST#16594819 v6 B-6 NOW Recreation and Tourism Year-round tourism and skiing-related businesses account for a significant portion of the employment and earned income of area residents. Vail Resorts is the largest employer in the County. The Ski Industry in the State. According to Colorado Ski Country USA ("CSCUSA"), a ski industry group, Colorado sees approximately 20% of U.S. skier visits annually. In June 2017, CSCUSA reported that visits at its 22 member ski areas totaled 7.3 million,representing a 6% increase in visitation over CSCUSA's five-year average and marking the fourth consecutive year that skier visits at CSCUSA resorts have outperformed such five-year average. Skier visits represent one person visiting a ski area for all or any part of a day or night for the purpose of skiing or snowboarding. One indicator of a significant ski industry is its economic impact. Research commissioned by CSCUSA and Vail Resorts in 2015 found that Colorado's ski industry generates a $4.8 billion annual economic impact, comprising a significant portion of the state's tourism and recreation sectors and supporting a sizeable share of the employment and tax base in Colorado's mountainous regions. In addition to the 500,000 Coloradans who skied during the 2013-14 season, more than seven million skier visits were generated by skiers and snowboarders from around the United States and the world. These guests on average spend more than$300 per skier visit,including the cost of more than 8.4 million nights in lodging accommodations. The Colorado ski industry's economic impact extends beyond resort communities. During the 2013-14 ski season, skiers and snowboarders accounted for 588,000 deplanements at Denver International Airport, or 8 percent of all non-connecting arrivals to Denver International Airport in that period. The Ski Industry in the Vail Valley. According to Vail Resort's most recent 10-K dated September 26,2016,Vail Mountain Ski Resort("Vail Mountain")was the second-most visited mountain resort in the United States for the 2015-2016 ski season, while Beaver Creek Ski Resort ("Beaver Creek") was the seventh most visited mountain resort in the United States for the 2015-2016 ski season. Both Vail Mountain and Beaver Creek are located within the County and served by the Airport.

The project included a complete renewal of guest rooms, creation of a new fine dining restaurant, a new lounge and bar area featuring live music, a luxury ski concierge and valet, and new retail outlets. A new Marriott Residence Inn has been proposed for the site of the old Roost Lodge in West Vail. As proposed, the new hotel would have 170 rooms, 113 deed-restricted apartments and 360 DMWEST#16594819 v6 B-8 below-ground parking spaces. Construction is expected to commence this summer.

Beneficial Owners should confirm the following information with DTC or the DTC Participants. None of the Corporation, the County, or the Underwriter has any responsibility or obligation to any Beneficial Owner with respect to (i) the accuracy of any records maintained by DTC or any DTC Participant, (ii) the distribution by DTC or any DTC Participant of any notice that is permitted or required to be given to the registered owners of the Series 2017 Bonds under the Indenture, (iii) the payment by DTC or any DTC Participant of any amounts received under the Indenture with respect to the Series 2017 Bonds, (iv) any consent given or other action taken by DTC or its nominee as the owner of Series 2017 Bonds or(v) any other related matter. DTC will act as securities depository for the Series 2017 Bonds. The Series 2017 Bonds will be issued as fully-registered securities registered in the name of Cede & Co. (DTC's partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered Series 2017 Bond certificate will be issued for the Series 2017 Bonds, in the aggregate principal amount thereof, and will be deposited with DTC. DTC, the world's largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non- U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC's participants ("Direct Participants") deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between Direct Participants' accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation ("DTCC"). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly ("Indirect Participants"). DTC has S&P's highest rating: "AAA." The DTC Rules applicable to its Participants are on file with the Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com and www.dtc.org. DMWEST#16594819 v6 G-1 The Corporation undertakes no responsibility for and makes no representations as to the accuracy or the completeness of the content of such material contained on such websites as described in the preceding sentence, including,but not limited to, updates of such information or links to other internet sites accessed through the aforementioned websites. Purchases of Series 2017 Bonds under the DTC system must be made by or through Direct Participants, which will receive a credit for the Bonds on DTC's records. The ownership interest of each Beneficial Owner is in turn recorded on the records of Direct and Indirect Participants. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Series 2017 Bonds are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in the Series 2011Bonds except in the event that use of the book-entry system for the Series 2017 Bonds is discontinued. To facilitate subsequent transfers, all Series 2017 Bonds deposited by Direct Participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of Series 2017 Bonds with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Series 2017 Bonds; DTC's records reflect only the identity of the Direct Participants to whose accounts such Series 2017 Bonds are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers. Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial Owners of Series 2017 Bonds may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the Series 2017 Bonds, such as redemptions, defaults and proposed amendments to the Indenture. For example, Beneficial Owners of Series 2017 Bonds may wish to ascertain that the nominee holding the Series 2017 Bonds for their benefit has agreed to obtain and transmit notices to Beneficial Owners. In the alternative, Beneficial Owners may wish to provide their names and addresses to the Registrar and request that copies of the notices be provided directly to them. Redemption notices will be sent to DTC. If less than all of the Series 2017 Bonds are being redeemed, DTC's practice is to determine by lot the amount of the interest of each Direct Participant in such maturity to be redeemed. Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the Series 2017 Bonds unless authorized by a Direct Participant in accordance with DTC's MMI Procedures. Under its usual procedures, DTC mails an Omnibus Proxy to the issuer DMWEST#16594819 v6 G-2 as soon as possible after the record date. The Omnibus Proxy assigns Cede &Co.'s consenting or voting rights to those Direct Participants to whose accounts the Series 2017 Bonds are credited on the record date (identified in a listing attached to the Omnibus Proxy). Payments with respect to the Series 2017 Bonds will be made to Cede & Co. or such other nominee as may be requested by an authorized representative of DTC. DTC's practice is to credit Direct Participants' accounts upon DTC's receipt of funds and corresponding detail information from the Corporation or the Trustee on the payable date in accordance with their respective holdings shown on DTC's records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such Participants and not of DTC, the Trustee or the Corporation, subject to any statutory or regulatory requirements as may be in effect from time to time. Payments with respect to the Series 2017 Bonds to Cede & Co., or to such other nominee as may be requested by an authorized representative of DTC, is the responsibility of the Corporation or the Trustee, disbursement of such payments to Direct Participants is the responsibility of DTC and disbursement of such payments to the Beneficial Owners is the responsibility of Direct and Indirect Participants. DTC may discontinue providing its services as securities depository with respect to the Series 2017 Bonds at any time by giving reasonable notice to the Corporation. Under such circumstances, in the event that a successor securities depository is not obtained, Series 2017 Bond certificates are required to be printed and delivered as provided in the Indenture. The Corporation may at any time decide to discontinue use of the system of book-entry- only transfers through DTC (or a successor securities depository) with respect to the Series 2017 Bonds. In that event, Series 2017 Bond certificates will be printed and delivered to DTC. DMWEST#16594819 v6 G-3
