EXECUTION VERSION

FIRST AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT

     This FIRST AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT (this “Amendment”) is dated as of August 28, 2006, by and among PEROT SYSTEMS CORPORATION, a Delaware corporation (the "Borrower”), the LENDERS party hereto (the “Lenders”) and JPMORGAN CHASE BANK, N.A., as Administrative Agent (in such capacity, the “Administrative Agent”).

RECITALS

     A. The Borrower, the Lenders, the Administrative Agent, KeyBank National Association, SunTrust Bank and Wells Fargo Bank, National Association, as Co-Syndication Agents, and Wachovia Bank, N.A., as Documentation Agent, are parties to an Amended and Restated Credit Agreement dated as of March 3, 2005 (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”). Capitalized terms used but not defined herein have the meanings set forth in the Credit Agreement.

     B. The Borrower has notified the Administrative Agent and the Lenders that the quarterly financial statements to be delivered by the Borrower pursuant to Section 5.01(b) of the Credit Agreement for the Borrower’s fiscal quarter ended June 30, 2006 (the “2Q 2006 Financials”) may indicate that the Borrower did not comply with clause (i) of the definition of “Minimum Recourse Coverage” for the period of four consecutive fiscal quarters ended on such date (the “Covenant Departure”).

     C. The Borrower has requested that the Lenders consent to the Covenant Departure and waive the requirement under Section 5.11(b) of the Credit Agreement, resulting from the Covenant Departure, for the Borrower to cause one or more Domestic Subsidiaries to become Guarantors within 10 days after delivery of the 2Q 2006 Financials.

     D. The Borrower has further requested that the Lenders agree to amend the Credit Agreement in certain respects, as more particularly set forth herein.

     E. The Lenders are willing to provide the requested consent and waiver, and to so amend the Credit Agreement, subject to the terms and conditions and in reliance upon the representations and warranties of the Borrower set forth herein.

     NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Borrower and the Lenders agree as follows:

     SECTION 1. Limited Waiver and Limited Consent. Subject to the terms and conditions set forth in this Amendment, and in reliance upon the representations and warranties of the Borrower made herein, the Lenders hereby consent to the Covenant Departure and waive the requirement under Section 5.11(b) of the Credit Agreement, resulting from the Covenant Departure, for the Borrower to cause one or more Domestic Subsidiaries to become Guarantors within 10 days after delivery of the 2Q 2006 Financials; provided that such consent and waiver

shall apply only to the failure to comply with clause (i) of the definition of “Minimum Recourse Coverage” with respect to the period of four consecutive fiscal quarters of the Borrower ended June 30, 2006, and the resulting requirement under Section 5.11(b) for Borrower to cause one or more Domestic Subsidiaries to become Guarantors within 10 days after delivery of its financial statements for the period ended June 30, 2006. The foregoing consent and waiver is limited as described in the immediately preceding sentence, and shall not apply to any failure to comply with Sections 5.11(a) and 5.11(b) of the Credit Agreement in respect of any other period or under any other circumstance, nor to any failure to comply with any other provision of the Credit Agreement or any other Credit Document under any circumstance.

     SECTION 2. Amendments to Credit Agreement. Subject to the terms and conditions set forth in this Amendment, and in reliance upon the representations and warranties of the Borrower made herein, the Lenders and the Borrower hereby amend the Credit Agreement as follows:

     (a) Section 1.01 (Defined Terms) of the Credit Agreement is hereby amended by replacing “March 2, 2010” with “August 28, 2011” in the definition of “Maturity Date” therein.

     (b) Section 1.01 (Defined Terms) of the Credit Agreement is hereby further amended by adding a new definition of “First Amendment Effective Date” in the appropriate alphabetical position therein, such new definition to read as follows:

     ““First Amendment Effective Date” means August 28, 2006.”

     (c) Section 1.01 (Defined Terms) of the Credit Agreement is hereby further amended by deleting the definitions of “Applicable Rate”, “Consolidated EBIT” and “Consolidated EBITDA” therein in their entirety and replacing them with the following:

     ““Applicable Rate” means, for any day, with respect to any ABR Loan or Eurodollar Loan, or with respect to the facility fees payable hereunder, as the case may be, the applicable rate per annum set forth below under the caption “ABR Spread”, “Eurodollar Spread” or “Facility Fee Rate”, as the case may be, based upon the Debt/EBITDA Ratio applicable on such date (calculated in accordance with Section 6.08(a)), as follows:

Level:		Debt/EBITDA Ratio:		ABR Spread				Eurodollar Spread				Facility Fee Rate
IV		Greater than or equal to 2.00 to 1.00			0.250	%			1.000	%			0.200	%
III		Less than 2.00 to 1.00, but greater than or equal to 1.50 to 1.00			0.000	%			0.750	%			0.150	%
II		Less than 1.50 to 1.00, but greater than or equal to 1.00 to 1.00			0.000	%			0.625	%			0.125	%
I		Less than 1.00 to 1.00			0.000	%			0.500	%			0.100	%

On the First Amendment Effective Date and continuing through and including the day immediately preceding the first Adjustment Date occurring after the First Amendment Effective Date, the ABR Spread shall be 0.000%, the Eurodollar Spread shall be 0.500%, and the Facility Fee Rate shall be 0.100% per annum, and for each period thereafter beginning on an Adjustment Date and ending on the day immediately preceding the next succeeding Adjustment Date, the Applicable Rate shall be as set forth opposite the applicable Debt/EBITDA Ratio in the table above, as determined at the end of the most recently ended fiscal quarter prior to the applicable Adjustment Date in accordance with the definition of “Adjustment Date”; provided, however, that if the Borrower fails to furnish to the Administrative Agent the financial statements of the Borrower and related certificate of a Financial Officer of the Borrower with respect to any fiscal quarter within the time periods specified in Section 5.01(a) or 5.01(b), as applicable, then the Applicable Rate prescribed in Level IV above shall apply as of the date such financial statements were required to be delivered until the day immediately preceding the date such financial statements and compliance certificate are so delivered.

Notwithstanding the foregoing, if either S&P or Moody’s have at any time after the Effective Date established ratings with respect to Index Debt of the Borrower, the “Applicable Rate” shall instead at all times thereafter be equal to the applicable percentage rate per annum set forth on the table below, based upon the ratings by S&P and Moody’s, respectively, applicable at such time to the Index Debt:

Index Debt Rating:		Index Debt Rating:
S&P		Moody’s		ABR Spread		Eurodollar Spread		Facility Fee Rate
Greater than or equal to A-		Greater than or equal to A3		0.000%		0.300%		0.070%
BBB+		Baa1		0.000%		0.400%		0.080%
BBB		Baa2		0.000%		0.500%		0.100%
BBB-		Baa3		0.000%		0.625%		0.125%
less than BBB-		less than Baa3		0.000%		0.875%		0.175%

provided, however, that if at any time the Facility Usage is greater than 50% of the aggregate amount of the Lender’s Commitments at such time, then the Applicable Margin with respect to Eurodollar Loans determined with reference to the table above will be increased 0.125%.

For purposes of the foregoing, (a) if either Moody’s or S&P shall not have in effect a rating for the Index Debt (other than by reason of the circumstances referred to in the last sentence of this definition), then such rating agency shall be deemed to have established a rating as set forth in the bottom row of the table above; (b) if the ratings established or deemed to have been established by Moody’s and S&P for the Index Debt shall fall within different categories, the Applicable Margin shall be based on the higher of the two ratings unless one of the two ratings is two or more categories lower than the other, in which case the Applicable Rate shall be determined by reference to the category next above that of the lower of the two ratings; and (c) if the ratings established or deemed to have been established by Moody’s and S&P for the Index Debt shall be changed (other than as a result of a change in the rating system of Moody’s or S&P), such change shall be effective as of the date on which it is first announced by the applicable rating agency, irrespective of when notice of such change shall have been furnished by the Borrower to the Administrative Agent and the Lenders. Each change in the Applicable Rate shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of Moody’s or S&P shall change, or if either such rating agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the Lenders shall negotiate in good faith to amend the definition of “Applicable Rate” to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Rate shall be determined by reference to the rating most recently in effect prior to such change or cessation.”

““Consolidated EBIT” means, for any period, on a consolidated basis for the Borrower and its Subsidiaries, the sum of the amounts for such period, without duplication, of: (a) Consolidated Net Income, plus (b) charges against income for foreign, federal, state, and local taxes, to the extent deducted in computing Consolidated Net Income, plus (c) Consolidated Interest Expense, plus (d) extraordinary or non-recurring non-cash losses to the extent deducted in computing Consolidated Net Income, plus (e) non-cash stock compensation expense recorded in accordance with FASB Statement 123R, which the Borrower adopted as of January 1, 2006, to the extent deducted in computing Consolidated Net Income, minus (f) extraordinary or non-recurring non-cash gains to the extent included in computing Consolidated Net Income, calculated on a rolling four-quarter basis for covenant compliance purposes.”

““Consolidated EBITDA” means, for any period, on a consolidated basis for the Borrower and its Subsidiaries, the sum of the amounts for such period, without duplication, of: (a) Consolidated Net Income, plus (b) charges against income for foreign, federal, state, and local taxes, to the extent deducted in computing Consolidated Net Income, plus (c) Consolidated Interest Expense, plus (d) depreciation expense, to the extent deducted in computing Consolidated Net Income, plus (e) amortization expense, including, without limitation, amortization of goodwill, other intangible assets and Transaction Expenses, to the extent deducted in computing Consolidated Net Income, plus (f) extraordinary or non-recurring non-cash losses to the extent deducted in computing Consolidated Net Income, plus (g) non-cash stock compensation expense recorded in accordance with FASB Statement 123R, which the Borrower adopted as of

January 1, 2006, to the extent deducted in computing Consolidated Net Income, minus (h) extraordinary or non-recurring non-cash gains to the extent included in computing Consolidated Net Income, calculated on a rolling four-quarter basis for covenant compliance purposes.”

No term, covenant or provision of the Credit Agreement or any other Credit Document is intended to be amended hereby except to the extent specifically set forth above in this Section 1.
