Effective on (and subject to the occurrence of) the Second Amendment Effective Date (as defined below), the Credit Agreement shall be amended as follows: 1.1 Article I shall be amended by inserting the following definitions in the appropriate alphabetical order: "Designating Lender" - see Section 12.6. "SPV" - see Section 12.6. 1.2 The definition of the term "Commitment" shall be amended by deleting the phrase "opposite its signature below" therein and substituting the phrase "in Schedule 2" therefor. 1.3 The definition of the term "Facility Termination Date" shall be amended by deleting the date "March 6, 2001" therein and substituting the date "October 30, 2001" therefor. 1.4 The definition of the term "Parent" shall be amended by deleting the name "Indiana Energy, Inc." therein and substituting the name "Vectren Utility Holdings, Inc." therefor. 1.5 The following Section 12.6 shall be added to the Credit Agreement in the appropriate numeric sequence: 12.6. Designation. (i) Notwithstanding anything to the contrary contained herein, any Lender (a 'Designating Lender') may grant to one or more special purpose funding vehicles (each an 'SPV'), identified as such in writing from time to time by the Designating Lender to the Administrative Agent, the option to provide to the Borrowers all or any part of any Loan that such Designating Lender would otherwise be obligated to make to the Borrowers pursuant to this Agreement; provided that (a) nothing herein shall constitute a commitment by any SPV to make any Loan, (b) if an SPV elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Designating Lender shall be obligated to make such Loan pursuant to the terms hereof, and (c) the Designating Lender shall remain liable for any indemnity or other payment obligation with respect to its Commitment hereunder. The making of a Loan by an SPV hereunder shall utilize the Commitment of the Designating Lender to the same extent, and as if, such Loan were made by such Designating Lender. (ii) As to any Loan or portion thereof made by it, each SPV shall have all the rights that a Lender making such Loan or portion thereof would have had under this Agreement; provided, however, that each SPV shall have granted to its Designating Lender an irrevocable power of attorney to deliver and receive all communication and notices under this Agreement and any other Loan Documents and to exercise on such SPV's behalf all of such SPV's voting rights under this Agreement. No additional Note shall be required to evidence the Loans or portion thereof made by an SPV; and the related Designating Lender shall be deemed to hold its Note as agent for such SPV to the extent of each Loan or portion thereof funded by such SPV. In addition, any payments for the account of any SPV shall be paid to its Designating Lender as agent for such SPV. (iii) Each party hereto hereby agrees that no SPV shall be liable for any indemnity or payment under this Agreement for which a Lender would otherwise be liable. In furtherance of the foregoing, each party hereto hereby agrees (which agreements shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPV, it will not institute against, or join any other person in instituting against, such SPV any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding under the laws of the United States or any State thereof. (iv) In addition, notwithstanding anything to the contrary contained in this Section 12.6 or otherwise in this Agreement, any SPV may (a) at any time and without paying any processing fee therefor, assign or participate all or a portion of is interest in any Loan to the Designating Lender or to any financial institution providing liquidity and/or credit support to or for the account of such SPV to support the funding or maintenance of Loans and (b) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPV. This Section 12.6 may not be amended without the written consent of each Designating Lender affected thereby. 1.6 The signature pages shall be amended by deleting the following: (i) the term "Commitments"; (ii) the amount "$35,000,000" opposite the signatures of BANK ONE, INDIANA, N.A. and ABN AMRO BANK N.V.; (iii) the amount "$30,000,000" opposite the signature of NATIONAL CITY BANK OF INDIANA; and (iv) "$100,000,000 TOTAL". 1.7 The column entitled "Level II Status" set forth on the Pricing Schedule shall be amended by deleting the figure "0.20%" therein and substituting the figure "0.25%" therefor. 1.8 The Commitments of the Lenders on the Second Amendment Effective Date shall be as set forth on Schedule 2 hereto, and such Schedule 2 is added to the Credit Agreement as Schedule 2 thereto.
