The calculation of Fixed Charges Ratio shall be calculated beginning in the second fiscal quarter of the fiscal year ending August 31, 2005 after giving pro forma effect to the consummation of the Transactions.

2.04. A new Section 2.2(e) shall be inserted in the Credit Agreement reading as follows:

“(e) If the sum of the aggregate outstanding principal amount of the Revolving Credit Loans plus the Financial LC Obligations exceeds the Aggregate Revolving Credit and Financial LC Commitment, the Borrower shall, first, immediately repay the principal of the Revolving Credit Loans and, second (upon all of the Revolving Credit Loans having been paid in full), provide cash cover for outstanding Letters of Credit, in an aggregate amount at least equal to such excess.”

(a) The Borrower agrees to pay to the Agent for the account of each Lender according to its Pro Rata Share a commitment fee at a per annum rate equal to the Applicable Fee Rate on the average daily excess of the Aggregate Commitment over the Aggregate Outstanding Credit Exposure (other than Swing Line Loans) from the date hereof to and including the Facility Termination Date, payable quarterly in arrears on each Payment Date hereafter and on the Facility Termination Date.

(b) The Borrower may permanently reduce the Aggregate Commitment in whole or in part by reducing the Aggregate Facility LC Commitment in integral multiples of $5,000,000, upon at least three Business Day’s prior written notice to the Agent, which notice shall specify the amount of any such reduction, provided, however, that (i) the amount of the Aggregate Commitment may not be reduced below the Aggregate Outstanding Credit Exposure and (ii) the Aggregate Facility LC Commitment shall not be reduced below the amount of the LC Obligations. All accrued commitment fees shall be payable on the effective date of any termination of the obligations of the Lenders to make Credit Extensions hereunder.”

2.06. Increase of the Facility LC Commitments. A new Section 2.21 shall be inserted in the Credit Agreement reading as follows:

“2.21. Increase of the Commitments.

(a) Subject to Section 2.21(b) below, the amount of the Aggregate Facility LC Commitment may be increased by an amount not exceeding $200,000,000 at the request of the Borrower from time to time as follows: (i) the Borrower shall designate one or more financial institutions acceptable to the Administrative Agent (which acceptance will not be unreasonably withheld), to assume Facility LC Commitments in an aggregate amount equal to the amount of such increase and (ii) on the date that such increase becomes effective, Revolving Credit Loans shall be repaid and/or borrowed to the extent necessary such that they shall be held by the Lenders ratably in proportion to their respective Pro Rata Shares (determined after giving effect to such designations). In the event of the designation by the Borrower of a financial institution pursuant to clause (i) of the preceding sentence (each financial institution being so designated being referred to herein as an “Assuming Lender”), and subject to the execution and delivery to the Administrative Agent by the Borrower and such Assuming Lender of documentation satisfactory to the Administrative Agent in its reasonable discretion to effect such designation: (x) such Assuming Lender shall become (or, if such Assuming Lender was theretofore a Lender shall continue as) a Lender having a Facility LC Commitment equal to the amount of such increase allocated to such Assuming Lender in such designation (plus, if such Assuming Lender was theretofore a Lender, the amount of the Facility LC Commitment held by such Assuming Lender immediately prior to such designation) and (y) the participations in outstanding Letters of Credit and Reimbursement Obligations shall thereupon automatically and without further action be re-allocated all to the extent necessary such that the participations in such Letters of Credit and Reimbursement Obligations shall be held by the Lenders ratably in proportion to their respective Pro Rata Shares (determined after giving effect to such designations). In no event shall any Lender be required to become an Assuming Lender.

(b) The Borrower shall furnish to the Agent, each in form and substance satisfactory to the Agent and to the extent required by the title insurance company: (i) evidence that any amendment to the Mortgages to reflect the increase in Commitments pursuant to the Lender Addenda shall have been made, within 30 days after the date of such increase in Commitments and (ii) evidence satisfactory to the Agent that date down endorsements or the functional equivalent thereof, current to the date of the recording of the amendments to the Mortgages that reflect the increase in Commitments pursuant to the Lender Addenda, are issued in connection with each of the existing Mortgage Policies issued, within 60 days after the date of such increase in Commitments; provided that the Agent shall be able to grant extensions in its sole discretion for the date down endorsements or functional equivalent thereof for the Mortgages identified on Schedule I. The failure of the Borrower to furnish any document in clauses (i) and (ii) above within the time frames noted above shall constitute a Default under the Credit Agreement and any other Loan Document.

(c) Each increase in the Aggregate Facility LC Commitment pursuant to Section 2.21(a) shall automatically and simultaneously increase the Aggregate Commitment by the same amount.”

2.07. Schedule 2.19. Schedule 2.19 of the Credit Agreement shall be amended by adding thereto the descriptions of the Letters of Credit listed on Annex A attached hereto.

2.08. Security Agreement. The reference in the second paragraph of the preamble of the Security Agreement to “$550,000,000” shall be replaced by “$550,000,000 (as such amount may be increased as provided in the Credit Agreement)”.

Section 3. Representations and Warranties. The Borrower represents and warrants to the Lenders that the representations and warranties set forth in Article V of the Credit Agreement are true and correct on the date hereof as if made on and as of the date hereof (except to the extent any such representation or warranty is stated to relate solely to an earlier date, in which case such representation or warranty shall have been true and correct on and as of such earlier date) and as if each reference in said Article V to “this Agreement” included reference to this Amendment No. 2.

Section 4. Waiver. The Borrower hereby requests, and the Agent hereby consents to, a waiver of the default which occurred on November 2, 2005, when the Guarantor SWINC Acquisition Five, L.L.C. changed its name to International Consultants, L.L.C., without providing thirty (30) days’ prior written notice to the Agent in accordance with the terms of Section 5.07 of the Security Agreement.

Section 5. Conditions Precedent. The amendments set forth in Section 2 hereof and the waiver set forth in Section 4 hereof shall become effective, as of the date hereof, upon:
