8

(b)   So long as (i) the type and terms of the Seahawk Credit Support Instrument that Seahawk has posted or proposes to post are acceptable to Pride, (ii) the issuer thereof is acceptable to Pride, (iii) Seahawk has provided to Pride all the information specified in Section 2.2(a) and, if any, all other information timely requested by Pride pursuant to Section 2.2(c) and (iv) no Event of Default then exists (and Seahawk certifies in writing that no Event of Default then exists), Pride shall deliver to the applicable Seahawk Credit Support Provider on the Proposed Credit Support Delivery Date (or, if reasonably required by such Seahawk Credit Support Provider and if it is commercially reasonable for Pride to do so, on a day not more than three Business Days prior to the Proposed Credit Support Delivery Date) one or more Pride Credit Support Instruments that support Seahawk’s or any of its Subsidiaries’ payment obligations in respect of such Seahawk Credit Support Instrument.

(c)   If (i) the type or terms of the Seahawk Credit Support Instrument that Seahawk has posted or proposes to post are not acceptable to Pride, (ii) the issuer of such Seahawk Credit Support Instrument or Instruments is not acceptable to Pride and/or (iii) Pride requires any information other than as specified in Section 2.2(a) which it reasonably believes is necessary for it to issue the requested Pride Credit Support Instrument, then Pride shall notify Seahawk (in writing or by way of a telephone call to an officer of Seahawk, which telephone call shall be promptly followed by a confirmatory writing to Seahawk), within 10 days after Pride’s receipt of the applicable request made by Seahawk pursuant to Section 2.2(a), of the type of Seahawk Credit Support Instrument, or the changes in the terms thereof, that would be acceptable to Pride, the names of potential issuers of Seahawk Credit Support Instruments that would be acceptable to Pride, and/or such other information that Pride reasonably believes is necessary for it to issue the requested Pride Credit Support Instrument, as applicable.

9

provide such Pride Credit Support Instrument unless a Change in Circumstance has occurred (in which case Pride shall be able to refuse to provide such Pride Credit Support Instrument). Seahawk acknowledges and agrees that the Seahawk Credit Support Instruments that are acceptable to Pride may be more expensive for Seahawk to procure than other types of Credit Support Instruments, and that the fees and charges of issuers of Seahawk Credit Support Instruments that are acceptable to Pride may be greater than the fees and charges of other issuers of Credit Support Instruments. Pride acknowledges and agrees that the Existing Credit Support Instruments are acceptable to Pride and that each issuer of an Existing Credit Support Instrument is acceptable to Pride (but only in its capacity as the issuer of such Existing Credit Support Instrument); provided that Pride shall have the right to require Seahawk to provide one or more replacement Seahawk Credit Support Instruments for the Existing Credit Support Instruments on the terms and conditions set forth in Section 2.2(e).

The failure of Seahawk to arrange for the issuance of such a replacement Seahawk Credit Support Instrument on such date shall constitute an Event of Default under Section 3.1(c).

Section 2.3   Reimbursement of Amounts Paid under Pride Credit Support Instruments.   In the event that Pride makes any payment pursuant to or in connection with any Pride Credit Support Instrument (a “Pride Payment”), Seahawk shall immediately and unconditionally pay to Pride upon demand the amount of such payment. If Seahawk shall fail to pay to Pride the amount of any such Pride Payment immediately upon demand, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to 7.50% plus the LIBO Rate.

Section 2.5   Reductions in Credit Support Exposure.

(a)   If at any time any Seahawk Credit Support Provider notifies Seahawk or any of its Subsidiaries in writing (including by electronic mail) that such Seahawk Credit Support Provider no longer requires the full value of any Pride Credit Support Instrument provided in its favor to remain effective, Seahawk shall promptly, and in any event within three Business Days after receiving such notification, notify Pride thereof and shall take all commercially reasonable actions necessary to ensure that the value of such Pride Credit Support Instrument is reduced by the amount that such Seahawk Credit Support Provider no longer requires be maintained.

(b)   If, as a result of a settlement or other disposition of all or any part of any Specified Tax Assessment Contest or otherwise, the maximum amount payable under any Seahawk Credit Support Instrument is reduced or any Seahawk Credit Support Instrument is terminated, then Seahawk shall promptly, and in any event within three Business Days after such reduction or termination, notify Pride thereof and take all commercially reasonable actions necessary to ensure that the value of the Pride Credit Support Instrument or Instruments supporting such Seahawk Credit Support Instrument is reduced by a corresponding amount or such Pride Credit Support Instrument or Instruments are terminated (and, if applicable, returned to Pride), as applicable.

For the avoidance of doubt, if Seahawk proposes to effect any increase in the amounts that may be payable by the applicable Seahawk Credit Support Provider to the Mexican Hacienda under any such Seahawk Credit Support Instrument other than as expressly contemplated herein, Pride’s withholding of its consent to such increase shall be deemed to be reasonable.
