3. Payments.

3.1 In consideration for the foregoing releases in paragraph 2, MasterCard will pay to Discover $862.5 million on or before November 14, 2008.

3.2 In consideration for the foregoing release, Visa shall pay to Discover as follows: Four (4) payments as set forth herein, contingent on the performance of Discover Financial Services Volume. The amount of each of the first 3 payments will be 5% of the Discover Financial Services Volume for the Performance Period in which the payment is due up to the maximum amount for such Performance Period as set forth in Schedule A, provided however that if the payment for any of the first 3 Performance Periods is less than the applicable maximum payment for such Performance Period, the maximum payment for a future Performance Period or Periods shall be increased by the difference between the applicable maximum payment and such lesser amount as was actually due. The amount of the fourth payment will be 21% of the Discover Financial Services Volume for the final Performance Period set forth in Schedule A up to the maximum amount set forth in Schedule A (subject to adjustment in accordance with the preceding sentence) (plus Applicable Interest on the balance of the Visa Settlement Fund for the period between November 14 and the date of final payment) minus an amount equal to the difference, if any, between $1,415,625,000 and the actual amounts earned based on the performance of the Discover Financial Services Volume for each of the first three Performance Periods. Notwithstanding anything herein to the contrary, the maximum amount of the four (4) payments due from Visa is $1,887,500,000 plus Applicable Interest thereon for the period from November 14, 2008 through the date of final payment.

3.3 All such payments shall be made by wire transfer to the account designated by Discover in accordance with the notice provision herein.

3.4 If the amounts required to be paid pursuant to paragraph 3 of this Release and Settlement Agreement above are not paid as required, Discover may, at its option, commence an arbitration to collect such payments or declare a default of this Release and Settlement Agreement by the Party that has failed to make the required payment (the "Defaulting Party"). The Defaulting Party will have 30 days from receipt of any notice of default to cure such default by making the required payment. If the Defaulting Party fails to cure any default in the time provided, Discover, at its sole election, may declare this Release and Settlement Agreement null and void with respect to the Defaulting Party and, upon returning all settlement payments previously received from the Defaulting Party, Discover shall be entitled to reassert the Released Claims against the Visa Released Entities (if Visa is the Defaulting Party) or against the MasterCard Released Entities (if MasterCard is the Defaulting Party) to the full extent that such Released Claims could have been pursued in the absence of this Release and Settlement Agreement and any statute of limitations defense arising as a result of this Release and Settlement Agreement or its implementation is waived. For the avoidance of doubt, in the event of such termination, the Visa Released Entities and the MasterCard Released Entities reserve the right to assert all statute of limitations defenses against Released Claims that they would have been able to assert in the absence of this Release and Settlement Agreement or its implementation, except that the applicable statutes of limitations shall be tolled for a period from the Effective Date until 90 days following Discover's declaration of a default of this Release and Settlement Agreement.

This Release and Settlement Agreement shall take effect on the Effective Date.

4.2 Within seven days after the Effective Date, Discover shall dismiss the Litigation without prejudice, except that such dismissal shall have the effect of dismissal with prejudice with respect to any Party upon Discover's receipt of all settlement payments due from such Party pursuant to paragraph 3 of this Release and Settlement Agreement.

4.3 The Visa Released Entities and MasterCard Released Entities who do not appear on the signature lines below are acknowledged and agreed to be third-party beneficiaries of this Release and Settlement Agreement and have the same rights to enforce this Release and Settlement Agreement as the signatories hereto.

4.8 This Release and Settlement Agreement may be executed in counterparts with the same force and effect as if executed in one complete and original document.

4.9 This Release and Settlement Agreement may be amended or superseded only by a written agreement duly executed by all of the signatories hereto, and such amendments and superseding agreements, if any, may not affect or prejudice the rights and/or benefits accruing to the Visa Released Entities or MasterCard Released Entities.

4.10 The Parties agree to work in good faith to coordinate the timing of any public announcement regarding the existence or terms of this Release and Settlement Agreement. In any public statements regarding the Release and Settlement Agreement or the Claims asserted in the Litigation, no Party will discuss the merits of such Claims or disparage any other Party, provided that the foregoing is not intended to restrict discussion of the nature of such Claims, of facts already in the public domain, of existing published legal decisions or any disclosure required by law.
