     (b) Transactions occurring, or actions taken, on the Distribution Date but after the Second Distribution outside the ordinary course of business by, or with respect to, TSYS or any of its Affiliates shall be deemed subject to the “next day rule” of Treasury Regulation Section 1.1502-76(b)(1)(ii)(B) (and under any comparable or similar provision under state, local or foreign laws or regulations, provided that if there is no comparable or similar provision under state, local or foreign laws or regulations, then the transaction will be deemed subject to the “next day rule” and as such shall for purposes of this Agreement be treated (and consistently reported by the parties) as occurring in a Post-Distribution Tax Period of TSYS or a TSYS Affiliate, as appropriate).

     (c) Any Taxes for a Straddle Period shall, for purposes of this Agreement, be apportioned between the portion of the period ending on and including the Distribution Date and the portion of the period beginning after the Distribution Date, and each such portion of such period shall be deemed to be a taxable period (whether or not it is in fact a taxable period). Any allocation of income or deductions required to determine any Income Taxes for a Straddle Period shall be made by means of a closing of the books and records of TSYS and its Affiliates as of the close of business on the Distribution Date, provided that (i) Synovus may elect to allocate Tax Items (other than any extraordinary Tax Items) ratably in the month in which the Second Distribution occurs (and if Synovus so elects, TSYS shall so elect) as described in Treasury Regulations Section 1.1502-76(b)(2)(iii) and corresponding provisions of state, local, and foreign Tax laws; and (ii) subject to clause (i), exemptions, allowances or deductions that are calculated on an annual basis, and not on a closing of the books method (including, but not limited to, depreciation and amortization deductions) shall be allocated between the period ending on and including the Distribution Date and the period beginning after the Distribution Date based on the

number of days for the portion of the Straddle Period ending on and including the Distribution Date, on the one hand, and the number of days for the portion of the Straddle Period beginning after the Distribution Date, on the other hand.

     (d) Tax attributes determined on a consolidated or combined basis for taxable periods ending before or including the Distribution Date shall be allocated to Synovus and its Affiliates, and TSYS and its Affiliates, in accordance with the Code and the Treasury Regulations (and any applicable state, local, or foreign law or regulation). Synovus shall reasonably determine the amounts and proper allocation of such attributes. Synovus and TSYS agree to compute their Tax liabilities for taxable periods after the Distribution Date consistent with that determination and allocation, and treat the Tax Items as reflected on any federal (or applicable state, local or foreign) Income Tax Return filed by the parties as presumptively correct.

     Section 2.6 Tax Refunds. Except as provided in Section 2.7:

     (a) Synovus shall be entitled to all refunds (including refunds paid by means of a credit against other or future Tax liabilities) and credits with respect to any Tax for which Synovus is responsible under this Agreement, including by means of indemnification pursuant to the terms of this Agreement. TSYS shall be entitled to all refunds (including refunds paid by means of a credit against other or future Tax liabilities) and credits with respect to any Tax for which TSYS is responsible under this Agreement, including by means of indemnification pursuant to the terms of this Agreement.

     (b) Synovus and TSYS shall each forward to the other party, or reimburse such other party for, any refunds received by the first party and due to such other party pursuant to this Section within ten (10) days of the receipt of any such refund. Where a refund is received in the form of a credit against other or future Tax liabilities, reimbursement with respect to such refund shall be due in each case on the due date for payment of the Tax against which such refund has been credited. All payments made pursuant to this Section 2.6 shall describe in reasonable detail the basis for the calculation of the amount being paid.

     (c) If one party so requests, the other party (at the first party’s expense) may file for and pursue any refund to which the first party is entitled under this Section, provided that the other party shall not be required to file amended Tax Returns or otherwise pursue any refund on behalf of the first party if such other party determines, in its sole and absolute discretion, not to do so.

     (d) If the other party pays any amount to the first party under this Section 2.6 and, as a result of a subsequent Final Determination, the first party is not entitled to some or all of such amount, the other party shall notify the first party of the amount to be repaid to the other party, and the first party shall then repay such amount to the other party, together with any interest, fines, additions to Tax, penalties or any other additional amounts imposed by a Taxing Authority relating thereto.

     Section 2.7 Carrybacks.

     (a) Notwithstanding anything in this Agreement, TSYS shall file (or cause to be filed) on a timely basis any available election to waive the carryback of net operating losses, Tax credits or other Tax Items by TSYS or any Affiliate from a Post-Distribution Tax Period to a Straddle Period or Pre-Distribution Tax Period.

     (b) If, notwithstanding the provisions of Section 2.7(a), TSYS is required to carry back losses or credits, TSYS shall be entitled to any refund of any Tax obtained by Synovus or a Synovus Affiliate as a result of the carryback of losses or credits of TSYS or a TSYS Affiliate from any Post-Distribution Tax Period to any Pre-Distribution Tax Period or Straddle Period. Such refund is limited to the lesser of (i) the reduction in the TSYS Separate Tax Liability for all tax periods resulting from the carryback or (ii) the net amount received by Synovus or a Synovus Affiliate (by refund, offset against other Taxes, or otherwise), net of any Tax Detriment incurred by Synovus or such Affiliate resulting from such refund. Upon request by TSYS, Synovus shall advise TSYS of an estimate of any Tax Detriment Synovus projects will be associated with any carryback of losses or credits of TSYS and its Affiliates provided in this Section 2.7(b).

     (c) If TSYS has a Tax Item that must be carried back to any Pre-Distribution Tax Period, TSYS shall notify in writing Synovus that such Tax Item must be carried back. Such notification shall include a description in reasonable detail of the grounds for the refund and the amount thereof, and a certification by an appropriate officer of TSYS setting forth TSYS’s belief (together with supporting analysis) that the Tax treatment of such Tax Item is more likely than not correct, and is not a Tax Item arising from a Reportable Transaction.

     (d) If Synovus pays any amount to TSYS under Section 2.7(b) and, as a result of a subsequent Final Determination, TSYS is not entitled to some or all of such amount, Synovus shall notify TSYS of the amount to be repaid to Synovus, and TSYS shall then repay such amount to Synovus, together with any interest, fines, additions to Tax, penalties or any other additional amounts imposed by a Taxing Authority relating thereto.

     Section 2.8 Georgia Income Tax Credits.

     (a) If a member of the Synovus Group uses a Georgia income tax credit (including a carryover of an unused credit) that originally was earned by a member of the TSYS Group in a taxable year of such TSYS Group member ending on or before the Distribution Date, which tax credit subsequently was assigned to a member of the Synovus Group pursuant to with Section 48-7-42 of the Official Code of Georgia Annotated, Synovus shall make a payment to TSYS equal to the amount by which the net aggregate federal and state Income Tax liability of the Synovus Group actually was reduced as a result of the use of such assigned credit or carryover of such assigned credit.

     (b) The terms and conditions under which Georgia income tax credits earned by the TSYS Group in taxable periods beginning after the Distribution Date shall be assigned to members of the Synovus Group pursuant to Section 48-7-42 of the Official Code of Georgia Annotated are set forth on Exhibit A hereto.

Notwithstanding the foregoing, for any Tax Return described in the preceding sentence, (i) a party will not be required to follow Past Practices if, and to the extent that, it obtains either (A) the written consent of the other party (not to be unreasonably withheld) or (B) a “should” level opinion from a Tax Advisor that the proposed method of reporting is correct and (ii) Synovus shall have the right to determine which entities will be included in any Joint Return that it is responsible for filing.

     (b) The parties shall report the Transaction for all Tax purposes in a manner consistent with the Tax Opinion, unless, and only to the extent, an alternative position is required pursuant to a Final Determination.

     (a) Each of Synovus, CB&T and TSYS will not take or fail to take, or permit its Affiliates to take or fail to take, any action where that action or omission would (i) violate, be inconsistent with or cause to be untrue any covenant, representation or statement in, as

ARTICLE V

TAX CONTESTS; INDEMNIFICATION; COOPERATION

     Section 5.1 Notices.

     (a) Within 15 days after a party (the “Indemnitee”) becomes aware of the existence of a Tax Contest that may give rise to an indemnification claim under this Agreement by it against the other party (the “Indemnifying Party”), the Indemnitee shall promptly notify the Indemnifying Party of the Tax Contest, and thereafter shall promptly forward or make available to the Indemnifying Party copies of notices and communications with a Taxing Authority relating to such Tax Contest.

     (b) The Indemnifying Party shall not be responsible for any increase in amounts to which the Indemnitee is otherwise entitled to the extent that such increase results solely from the failure of the Indemnitee to provide timely notice as required pursuant to Section 5.1(a).

     Section 5.2 Control of Tax Contests.

     (a) Except as otherwise provided in Section 5.2(b), Synovus shall control, and shall have sole discretion in handling, settling or contesting, any Tax Contest relating to any Joint Returns, any Synovus Separate Returns or the Tax treatment of the Transactions, provided that (i) Synovus shall act in reasonable good faith in connection with its control of any such Tax Contests, (ii) TSYS shall have the right to participate in and advise on (including, without limitation, the opportunity to review and comment upon Synovus’s communications with the Taxing Authority, which comments shall be incorporated upon the consent of Synovus, not to be unreasonably withheld) such items for which TSYS could be liable under Article II as a result of such Tax Contest, and (iii) Synovus shall not settle or compromise items for which TSYS could be liable under Article II as a result of such Tax Contest without the prior written consent of TSYS, which shall not unreasonably be withheld.

     (b) Synovus and TSYS shall jointly control Tax Contests relating to Tax liability arising from the failure of the Transactions to qualify for tax-free treatment under Section 355 of the Code, if TSYS potentially would be liable to Synovus under Article II as a result of such Tax Contest. Neither party shall have the right to settle any such Tax Contest without the consent of the other party.

     (c) TSYS shall have sole control over any Tax Contest relating to the TSYS Separate Returns; provided, however, that if Synovus is responsible under this Agreement for any Taxes relating to such Tax Contest, then TSYS shall control, and shall have sole discretion in handling, settling or contesting such Tax Contest, provided that (i) TSYS shall act in reasonable good faith in connection with its control of any such Tax Contest, (ii) Synovus shall have the right to

participate in and advise on (including, without limitation, the opportunity to review and comment upon TSYS’s communications with the Taxing Authority, which comments shall be incorporated upon the consent of TSYS, not to be unreasonably withheld) such items for which Synovus could be liable under Article II as a result of such Tax Contest, and (iii) TSYS shall not settle or compromise items for which Synovus could be liable under Article II as a result of such Tax Contest without the prior written consent of Synovus, which shall not unreasonably be withheld.

     (d) Any out-of-pocket expenses incurred in handling, settling or contesting any Tax Contest shall be borne ratably by the parties based on their ultimate liability under this Agreement for the Taxes to which the Tax Contest relates.

     Section 5.3 Indemnification Payments.

     (a) An Indemnitee shall be entitled to make a claim for payments pursuant to this Agreement when the Indemnitee determines that it is entitled to such payment and the amount of such payment (including, for the avoidance of doubt, the finalization of a Tax Return before filing). The Indemnitee shall provide to the Indemnifying Party notice of such claim within 10 days of the date on which it first becomes so entitled to claim such payment, including a description of such claim and a detailed calculation of the amount of the indemnification payment that is claimed; provided, however, that no delay on the part of the Indemnitee in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is actually and materially prejudiced thereby. Except as provided in Section 5.3(b), the Indemnifying Party shall make the claimed payment to the Indemnitee within 10 days after receiving such notice, unless (and then only to the extent that) the Indemnifying Party reasonably disputes its liability for, or the amount of, such payment.

     (b) If the Indemnitee will be obligated to make the payment described in Section 5.3(a) to a Taxing Authority or other third party (including expenses reimbursable under this Agreement), the Indemnifying Party shall not be obligated to pay the Indemnitee more than 5 days before the Indemnitee incurs such expense or makes such payment. If the Indemnitee’s claim for payment arises from a payment that the Indemnifying Party will receive from a third party, such as a refund, the Indemnifying Party shall not be obligated to pay the Indemnitee until 5 days after the Indemnifying Party receives such payment.

     (c) In the case of a claim under Article II where no payment will be made to or received from a Taxing Authority, Section 5.3(b) shall be applied to the payments that would be made to or from a Taxing Authority if the TSYS Group were treated as a standalone group for all taxable periods.

     Section 5.4 Interest on Late Payments. Interest shall accrue with respect to any indemnification payment (including any disputed payment that is ultimately required to be made), not made within the period for payment, at the Applicable Rate.

     Section 5.5 Treatment of Payments. The amount of all indemnification obligations under this Agreement shall be decreased to take into account the Tax Benefits to the Indemnitee

of the deductibility of any indemnified item and shall be increased where necessary so that, after all the required deductions have been made and Taxes imposed, the Indemnitee receives the net amount it would have been entitled to receive under this Agreement in the absence of such deductions and Taxes. Any payments made to one party by another party pursuant to this Agreement shall be treated by the parties for all Tax purposes as a distribution by, or capital contribution to, TSYS, as the case may be, made immediately prior to the Distributions, except to the extent otherwise required by a Final Determination.

     Section 5.6 Expenses. Except as otherwise provided herein, each party and its Affiliates shall bear their own expenses incurred in connection with the preparation of Tax Returns, Tax Contests, and all other matters under this Agreement.

     Section 5.7 Cooperation. Each member of the Synovus Group and the TSYS Group shall cooperate fully with all reasonable requests from the other party in connection with the preparation and filing of Tax Returns, Tax Contests, and all other matters covered by this Agreement.

     (a) Such cooperation shall include:

     (i) the retention until the expiration of the applicable statute of limitations, and the provision upon request, of Tax Returns, books, records (including information regarding ownership and Tax basis of property), documentation and other information relating to Tax Returns, including accompanying schedules, related workpapers, and documents relating to rulings or other determinations by Taxing Authorities;

     (ii) the execution of any document that may be necessary or reasonably helpful in connection with any Tax Contest, the filing of a Tax Return by a member of the Synovus Group or the TSYS Group, obtaining a tax opinion or private letter ruling, or other matters covered by this Agreement, including certification (provided in such form as may be required by applicable law or reasonably requested and made to the best of a party’s knowledge) of the accuracy and completeness of the information it has supplied;

     (iii) the use of the parties’ reasonable best efforts to obtain any documentation that may be necessary or reasonably helpful in connection with any of the foregoing;

     (iv) the use of the parties’ reasonable best efforts to make the applicable party’s current or former officers, employees, agents and facilities available on a reasonable and mutually convenient basis in connection with the foregoing matters; and

     (v) making determinations with respect to actions described in Section 4.2(c)(i) and (e)(i) as promptly as practicable.

     (b) If a party fails to comply with any of its obligations set forth in this Section 5.7 upon reasonable request and notice by the other party, and such failure results in the imposition of additional Taxes, the nonperforming party shall be liable in full for such additional Taxes.

     Section 5.8 Confidentiality. Any information or documents relating to Taxes, including any such information provided under this Agreement, shall be kept confidential, except as may otherwise be necessary in connection with the filing of Tax Returns or with any Tax Contest. In addition, if Synovus, CB&T or TSYS determines that providing such information could be commercially detrimental, violate any law or agreement or waive any privilege, the parties shall use reasonable best efforts to permit compliance with the obligations under this Agreement in a manner that avoids any such harm or consequence.

     Section 5.9 Retention of Tax Records. On or prior to the Distribution Date, Synovus shall deliver or cause to be delivered to TSYS all materials, agreements, documents, books, records and files, if any, in the possession of Synovus or a Synovus Affiliate relating to Taxes of the TSYS Business. TSYS may request from Synovus and retain copies of, and Synovus may request from TSYS and retain copies of, (i) with respect to any Joint Return, all pro forma federal and state Tax Returns, supporting schedules and workpapers related to members of the TSYS Group, and (ii) any Separate Returns with respect to any Pre-Distribution Tax Period for any TSYS Group members, including supporting schedules and workpapers. Neither Synovus nor TSYS (nor any of their respective Affiliates) shall dispose of any documentation with respect to any Pre-Distribution Tax Period, including books, records, Tax Returns and all supporting schedules and information relating thereto, of any member of the other Group, or in the case of the TSYS Group any member included in a Joint Return, for a minimum of ten (10) years after the expiration of the applicable Pre-Distribution Tax Period (or, if later, until the expiration of the applicable statute of limitations), and each party shall promptly notify the other party in the event that any such documentation is inadvertently destroyed, damaged or otherwise disposed of. Prior to disposing of any such documentation, each party shall provide written notice to the other party describing the documentation proposed to be disposed of at least thirty (30) days prior to taking such action. The other party may arrange to take delivery of the documentation described in the notice at its own expense during the succeeding thirty (30) day period.

ARTICLE VI

DISPUTE RESOLUTION

Any Dispute arising under this Agreement shall be resolved pursuant to the negotiation and mediation procedures specified in Section 5.5(a) and (b) of the Distribution Agreement. Any such Dispute that has not been timely resolved in accordance with such procedures shall be finally resolved under the procedures set forth in this Article VI, in lieu of the arbitration procedures specified in Section 5.5(c) of the Distribution Agreement. Within ten (10) days following the failure of mediation under Section 5.5(c) of the Distribution Agreement, Synovus and TSYS shall jointly retain a nationally recognized law firm or “big four” accounting firm, which firm is independent of both parties (the “Independent Firm”), to resolve the Dispute. If the parties cannot jointly agree on an Independent Firm to resolve the Dispute within the ten (10) day period, then within a period of an additional ten (10) days, each party shall select a

nationally recognized law firm or “big four” accounting firm, which firm is independent of both parties, and those firms shall jointly select an Independent Firm which shall make the determination under this Article VI. The Independent Firm shall act as an arbitrator to resolve all points of disagreement, and its decision shall be final and binding upon all parties involved. The Independent Firm shall determine the appropriate outcome based on this Agreement with respect to each disputed item. The Independent Firm shall make such determinations within ninety (90) days from the date on which it is selected, unless the parties mutually agree to an extension of such period or the Independent Firm, in its discretion, determines that an extension of such period is warranted by exceptional circumstances. Any determination by the Independent Firm shall be in writing. Following the decision of the Independent Firm, Synovus and TSYS shall each take or cause to be taken any action necessary to implement the decision of the Independent Firm. The fees and expenses relating to the Independent Firm shall be borne by the party that such Independent Firm determines has lost the dispute. In all other events, the fees and expenses relating to the Independent Firm shall be shared based on the difference between the position taken by Synovus, on the one hand, and the position taken by TSYS, on the other hand, initially presented to the Independent Firm (based on the aggregate of all differences taken as a whole) and the final resolution as determined by the Independent Firm in proportion to the total difference between the initial position taken by Synovus and the initial position taken by TSYS. Any controversy concerning whether a Dispute is an arbitrable Dispute, whether arbitration has been waived, whether an assignee of this Agreement is bound to arbitrate, or as to the interpretation of enforceability of this Article VI shall be determined by the Independent Firm. In resolving any Dispute, the Parties intend that the Independent Firm apply the terms and conditions of this Agreement and the substantive laws of the State of Georgia, without regard to the choice of law principles thereof that could mandate the application of the laws of another jurisdiction. The Parties agree to comply with any award made by the Independent Firm pursuant to this Article VI and agree to enforcement of or entry of judgment upon such award, by any court of competent jurisdiction. The Independent Firm shall be entitled, if appropriate, to award any remedy in such proceedings available under this Agreement and Georgia law, including monetary damages, specific performance and all other forms of legal and equitable relief; provided, however, the Independent Firm shall not be entitled to award punitive, exemplary, multiple or any other forms of non-compensatory damages. Nothing contained herein is intended to or shall be construed to prevent any Party from applying to any court of competent jurisdiction for interim measures or other provisional relief in connection with the subject matter of any Dispute. Without prejudice to such provisional remedies as may be available under the jurisdiction of a court, the Independent Firm shall have full authority to grant provisional remedies and to direct the parties to request that any court modify or vacate any temporary or preliminary relief issued by such court, and to award damages for the failure of any party to respect the Independent Firm’s orders to that effect.
