WHEREAS, in connection with the issuance of the Bonds, the Authority and the Company entered into the Original Loan Agreement pursuant to which the Authority loaned the proceeds of the Bonds to the Company for the purpose of refunding certain prior revenue bonds of the Authority issued to finance certain projects on behalf of the Company, and the Company agreed, among other things, to make loan payments thereunder in amounts and at times sufficient to pay when due the principal of, premium, if any, and interest on the Bonds;

WHEREAS, the payment obligations of the Company under the Original Loan Agreement are evidenced by an Exempt Facilities Note issued thereunder to the Trustee (the “Note”) as assignee of the rights of the Authority in accordance with the Indenture;

WHEREAS, the Bonds are subject to mandatory tender for purchase on the date hereof in accordance with the provisions of Section 5.01(b)(i) and (iv) of the Indenture; and

WHEREAS, in connection with such mandatory tender and the remarketing of the Bonds in accordance with Section 5.02 of the Indenture, the Authority and the Company desire, with the consent of the Trustee pursuant to Section 7.5 of the Original Loan Agreement, to amend and supplement the Original Loan Agreement by entering into this First Supplement for the purpose of adding certain covenants and agreements of the Company to Article IV of the Original Loan Agreement.

EXHIBIT A

The Original Loan Agreement is hereby amended by adding the following Sections 4.15, 4.16, 4.17 and 4.18 to Article IV immediately after Section 4.14. Such Sections 4.15, 4.16, 4.17 and 4.18 shall be operative and binding upon the Company on and after the Effective Date until the Bonds are subject to mandatory purchase on September 1, 2020; provided, however, that the Company may omit in any particular instance to comply with any of such Sections if, before the time for such compliance, the holders of a majority in principal amount of the Bonds then Outstanding shall waive such compliance either in such instance or in such instance and generally thereafter:

Section 4.15. Limitation on Liens. a) The Company agrees that so long as any Bonds shall remain Outstanding, without the consent of the Trustee (which shall not be given without consent of the holders of a majority in principal amount of the Outstanding Bonds), the Company shall not create, incur or assume any Lien (other than Permitted Liens) upon any property of the Company, whether now owned or hereafter acquired, in order to secure any Debt of the Company. The foregoing agreement shall not restrict the ability of Subsidiaries or Affiliates of the Company to create, incur or assume any Lien upon their properties or assets.

(a) The provisions of subsection (a) above shall not prohibit the creation, issuance, incurrence or assumption of any Lien if either:

(i) the Company shall make effective provision whereby the Note shall be secured equally and ratably with all other Debt then outstanding under such Lien; or

(ii) (1) the Company shall deliver to the Trustee, as assignee of the Authority, bonds, notes or other evidences of indebtedness secured by the Lien which secures such Debt (hereinafter called “Secured Obligations”) (I) in an aggregate principal amount equal to the aggregate principal amount of the Bonds then Outstanding, (II) maturing (or being subject to mandatory redemption) on such dates and in such principal amounts that, at each stated maturity date of the Outstanding Bonds, there shall mature (or be redeemed) Secured Obligations equal in principal amount to such Bonds then to mature and (III) containing, in addition to any mandatory redemption provisions applicable to all Secured Obligations outstanding under such Lien and any mandatory redemption provisions contained therein pursuant to clause (II) above, mandatory redemption provisions correlative to the provisions, if any, for the mandatory redemption of the Bonds, as well as a provision for mandatory redemption upon an acceleration of the maturity of all Outstanding Bonds following an Event of Default under the Indenture (such mandatory redemption to be rescinded upon the rescission of such acceleration); it being expressly understood that such Secured Obligations (X) may, but need not, bear interest, (Y) may, but need not, contain provisions for the redemption thereof at the option of the issuer, any such redemption to be made at a redemption price or prices not less than the principal amount thereof and (Z) shall be held by the Trustee, as assignee of the Authority, for the benefit of the holders of all Bonds from time to time Outstanding subject to such terms and conditions relating to surrender to the Company, transfer restrictions, voting, application of payments of principal and interest and other matters as shall be set forth in an agreement supplemental hereto specifically providing for the delivery to the Trustee of such Secured Obligations; and

A-1

(A) anything in this Section 4.15, elsewhere in this Agreement, in the Indenture or in the Secured Obligations to the contrary notwithstanding, (I) the Secured Obligations shall not create any indebtedness of the Company in addition to the indebtedness created by the Loan Agreement and evidenced by the Note, (II) the amounts in respect of principal and/or interest due and payable by the Company on the Secured Obligations (x) shall be reduced to the extent that the Company’s obligation to make a corresponding Loan Payment (and the corresponding payment of principal of or interest on the Note) shall be reduced, as contemplated in Section 3.2(a) and in the Note, and (y) shall be fully or partially, as the case may be, satisfied and discharged in an amount equal to the corresponding amount, if any, paid by the Company under Section 3.2(a) and on the Note and (III) the Secured Obligations shall contain provisions to such effect.

(b) If the Company shall elect either of the alternatives described in Section 4.15(b) above, the Company shall deliver to the Trustee:

(i) an agreement supplemental to the Loan Agreement (A) together with any appropriate inter-creditor arrangements, whereby the Note shall be secured by the Lien referred to in Section 4.15(b) above equally and ratably with all other indebtedness secured by such Lien or (B) providing for the delivery to the Trustee, as assignee of the Authority, of Secured Obligations;

(ii) a certificate of an Authorized Representative of the Company (A) stating that, to the knowledge of the signer, (I) no Event of Default under either this Agreement or the Indenture has occurred and is continuing (other than an Event of Default described in clause (h) in Section 11.01 of the Indenture) and (II) no event has occurred and is continuing which entitles the secured party under such Lien to accelerate the maturity of the indebtedness outstanding thereunder and (B) stating the aggregate principal amount of indebtedness issuable, and then proposed to be issued, under and secured by such Lien; and

(iii) an opinion of Counsel (which may be Counsel to the Company) (A) if the Note is to be secured by such Lien, to the effect that the Note is entitled to the benefit of such Lien equally and ratably with all other indebtedness secured by such Lien or (B) if Secured Obligations are to be delivered to the Trustee, to the effect that such Secured Obligations have been duly issued under such Lien and constitute valid obligations, entitled to the benefit of such Lien equally and ratably with all other indebtedness then outstanding under such Lien.

Section 4.16. Limitation on Asset Sales. The Company agrees that so long as any Bonds shall remain Outstanding, and except for the disposition of all or substantially all of the assets of the Company pursuant to Section 4.1, the Company shall not, and shall not permit any of its Subsidiaries to, consummate any Asset Sale, if the aggregate net book value of all Asset Sales consummated during the four calendar quarters immediately preceding any date of determination would exceed 15% of the consolidated assets of the Company and its consolidated

A-2

Subsidiaries as of the beginning of the Company’s most recently ended full fiscal quarter; provided, however, that any such Asset Sale will be disregarded for purposes of the 15% limitation specified above (a) if such Asset Sale is in the ordinary course of business, (b) to the extent that the assets that are the subject of such Asset Sale are worn out or are no longer useful or necessary in connection with the operation of the business of the Company or any of its Subsidiaries, (c) to the extent the assets that are the subject of such Asset Sale are being transferred to a wholly-owned Subsidiary of the Company, (d) to the extent that such Asset Sale involves transfers of assets of or equity interests in connection with (i) the formation of any joint venture between the Company or any of its Subsidiaries and any other entity or (ii) any project development or acquisition activities, (e) if the proceeds of such Asset Sale (i) are, within 12 months of such Asset Sale, invested or reinvested by the Company or any Subsidiary in a Permitted Business, (ii) are used by the Company or a Subsidiary to repay Debt of the Company or such Subsidiary or (iii) are retained by the Company or any of its Subsidiaries or (f) to the extent the assets that are the subject of such Asset Sale are required to be sold to conform with governmental requirements. Additionally, if, prior to any Asset Sale that otherwise would cause the 15% limitation to be exceeded, Moody’s and S&P shall have confirmed the then current long term debt rating of the Bonds after giving effect to such Asset Sale, such Asset Sale shall also be disregarded for purposes of the foregoing limitations.

Section 4.17. Company Offer to Purchase Bonds upon Change of Control. (a) If a Change of Control Triggering Event occurs, the Company shall make an offer (a “Change of Control Offer”) to purchase all or any part (in authorized denominations) of the Bonds of each Bondholder at a purchase price in cash equal to 101% of the aggregate principal amount of Bonds purchased plus accrued and unpaid interest, if any, on the Bonds purchased to but excluding the date of purchase, subject to the rights of the Bondholders to receive interest due on an Interest Payment Date occurring on or prior to the Change of Control Payment Date (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, the Company shall give or cause to be given to each Bondholder notice, by first class mail postage prepaid or by Electronic Notice, or otherwise deliver notice in accordance with the applicable procedures of DTC, in any case with a copy to the Trustee, describing the transaction or transactions that constitute the Change of Control Triggering Event and stating:

(iv) that, unless the Company defaults in the payment of the Change of Control Payment, interest on all Bonds accepted for purchase pursuant to the Change of Control Offer will cease to be payable to the holders who tendered such Bonds after the Change of Control Payment Date;

A-3

(vi) any Bondholder will be entitled to withdraw its election, in whole or in part (in an authorized denomination), if the Company or its agent receives, not later than the expiration of such Change of Control Offer, a telegram, telex, facsimile transmission or letter setting forth the name of such Bondholder, the principal amount of Bonds delivered for purchase, and a statement that such Bondholder is withdrawing its election to have such Bonds, or the indicated portion thereof, purchased; and

(vii) that Bondholders whose Bonds are being purchased only in part will be issued new Bonds equal in principal amount to the unpurchased portion of the Bonds surrendered, which unpurchased portion must be in an authorized denomination.

(b) The Company will comply with the requirements of all federal and state securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the purchase of Bonds as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.17, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.17 by virtue of such compliance.

(c) On the Change of Control Payment Date, the Company will, to the extent lawful:

(i) accept for purchase all Bonds or portions of Bonds properly tendered pursuant to the Change of Control Offer; and

The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(e) Notwithstanding anything to the contrary in this Section 4.17, the Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if (i) a third party makes the Change of Control Offer in the manner, at or prior to the times and otherwise in compliance with the requirements set forth in this Section 4.17 and purchases all Bonds properly tendered and not withdrawn under the Change of Control Offer (it being

A-4

understood that such third-party may make a Change of Control Offer that is conditioned on and prior to the occurrence of a Change of Control pursuant to this clause), or (ii) unconditional notice of redemption of all Bonds has been given pursuant to Article IX of the Indenture, unless and until there is a default in payment of the applicable redemption price.

(f) A Change of Control Offer may be made in advance of a Change of Control Triggering Event, with the obligation to make the Change of Control Payment and the timing of such payment conditioned upon the consummation of the Change of Control, if a definitive agreement to effect a Change of Control is in place at the time of the Change of Control Offer.

(g) No purchase of Bonds by the Company pursuant to this Section 4.17 shall be deemed to be a payment or redemption of such Bonds by the Authority; such purchase shall not operate to extinguish or discharge the indebtedness evidenced by such Bonds; and upon such purchase, the Company shall become and be the holder of such Bonds for all purposes.
