RECITALS 1. The parties hereto have previously entered into the Credit Agreement which became effective on the Effective Date, January 24, 1992, upon the satisfaction of the conditions precedent thereto as set out in Section 8.01 of the Credit Agreement. 2. On January 27, 1992, TNP and TGC satisfied the conditions in Section 8.02 of the Credit Agreement to cause the occurrence of the Extension Date. Among other things, TNP issued its Series T Bonds and its First Secured Debentures, due January 15, 1999, and applied the net proceeds thereof to, among other things, purchase pro rata from the Banks $65,000,000 of the Project Loans outstanding under the Credit Agreement. The Project Loans acquired by TNP were, automatically upon their purchase by TNP, converted into the First Replacement Loan, evidenced by the First Replacement Note that is secured pursuant to the Security Documents pari passu with the other Obligations under the Credit Agreement and the other Project Documents. The First Secured Debentures are secured by TNP's pledge of the First Replacement Note to the First Debenture Trustee under the First Secured Debenture Indenture. As a result of the pledge of the First Replacement Note, the First Secured Debentures indirectly share pari passu in the Banks' Collateral. 3. TNP and TGC have the right to secure additional debt securities with the Collateral, subject to the terms and conditions of Section 9.32 of the Credit Agreement. Other than with respect to the January 27, 1992 transactions described in Recital 2 hereof, however, no specific procedures were AMENDMENT NO. 1 TO UNIT 1 FIRST AMENDED AND RESTATED PROJECT LOAN AND CREDIT AGREEMENT <PAGE 1> established in the Credit Agreement for TNP or TGC to secure additional debt securities with the Collateral. 4. The parties desire to amend the Credit Agreement as provided for in this Amendment to facilitate TNP's or TGC's securing certain additional debt securities and, upon the payment, prepayment or purchase in full of the Project Loans outstanding on the First Amendment Effective Date, all interest due and payable thereon and all other amounts due and payable by TNP and TGC to the Banks under the Credit Agreement and the other Project Documents, debt with the Collateral from time to time in furtherance of and as necessary for the parties to achieve the purposes and objectives, to perform the obligations and to exercise the rights, all as set forth in or contemplated by the Credit Agreement and as modified by this Amendment. 5. On July 2, 1993, TNP requested certain amendments to the Credit Agreement to provide, among other things, for the purchase by TNP, of $140,000,000 of Project Loans. On July 2, 1993, TNP requested certain amendments to the Unit 2 First Amended and Restated Project Loan and Credit Agreement dated as of January 8, 1992 among TNP, TGC II, the banks and the other parties thereto and Chase, as Agent (as amended, modified and supplemented and in effect from time to time, the "Unit 2 Credit Agreement") and simultaneously with the entering into of this Amendment the parties to the Unit 2 Credit Agreement are entering into Amendment No. 1 to the Unit 2 Credit Agreement in order to effect such amendments to the Unit 2 Credit Agreement. 6. The funds necessary for the payments, prepayments and purchase of Project Loans are expected to be provided by the issuance by TNP of new first mortgage bonds (the "New Bonds") in an aggregate principal amount of up to $100,000,000 under the TNP Bond Indenture and the issuance by TNP of Second Secured Debentures in an aggregate principal amount of up to $140,000,000 under the Second Secured Debenture Indenture. The $140,000,000 of Project Loans acquired by TNP will, automatically upon their purchase by TNP, be converted to the Second Replacement Loan, which Loan will be evidenced by the Second Replacement Note which Note will be secured pursuant to the Security Documents pari passu with the other Obligations under the Credit Agreement, the other Project Documents and the First Replacement Loan. The Second Secured Debentures will be secured by TNP's pledge of the Second Replacement Note to the Second Debenture Trustee under the Second Secured Debenture Indenture. As a result of the pledge of AMENDMENT NO. 1 TO UNIT 1 FIRST AMENDED AND RESTATED PROJECT LOAN AND CREDIT AGREEMENT <PAGE 2> the Second Replacement Note, the Second Secured Debentures will indirectly share pari passu in the Collateral securing the remaining Project Loans and the First Replacement Loan and, indirectly, the First Secured Debentures. 7. Certain provisions of this Amendment will become effective only upon the payment, prepayment and purchase of a portion of the Project Loans and the prepayment of certain of the indebtedness under the Unit 2 Credit Agreement and the satisfaction of certain other conditions. 8.
