The Responsible Company shall use its reasonable best efforts to make such Tax Return available for review as required under this paragraph sufficiently in advance of the due date (including extensions) for filing of such Tax Return to provide the requesting party with a meaningful opportunity to analyze and comment on such Tax Return.

(b) Execution of Returns Prepared by Other Party. In the case of any Tax Return which is required to be prepared and filed by the Responsible Company under this Agreement and which is required by law to be signed by the other Company (or by its authorized representative), the Company which is legally required to sign such Tax Return shall be required to sign such Tax Return unless there is no reasonable basis for the Tax treatment of an item reported on the Tax Return or the Tax treatment of an item reported on the Tax Return should, in the opinion (reasonably acceptable in form and substance to the Responsible Company) of a Tax advisor from a nationally recognized legal or accounting firm, subject the other Company (or its authorized representatives) to material penalties.

Section 4.07 Teradata Carrybacks and Claims for Refund. Teradata hereby agrees that, unless NCR consents in writing, no Adjustment Request with respect to any Tax Return for the Pre-Closing Period shall be filed; provided, however, that upon the reasonable request of Teradata, NCR shall use reasonable best efforts to make an Adjustment Request claiming a refund of Taxes for the Pre-Closing Period with respect to a Teradata Carryback arising in a Post-Closing Period related to U.S. federal or State Taxes (any such Adjustment Request to be prepared and filed by NCR).

Section 4.08 Apportionment of Earnings and Profits and Tax Attributes. NCR shall in good faith advise Teradata in writing of the portion, if any, of any earnings and profits, Tax Attribute, overall foreign loss, capitalized research and development expenditures or other consolidated, combined or unitary attribute which NCR determines shall be allocated or apportioned to the Teradata Group under applicable law. Teradata and all members of the Teradata Group shall prepare all Tax Returns in accordance with such written notice. As soon as practicable after receipt of a written request from Teradata, NCR shall provide copies of any studies, reports, and workpapers supporting such allocations and apportionments. In the event of

a subsequent adjustment by the applicable Tax Authority to such allocations and apportionments, NCR shall promptly notify Teradata in writing of such adjustment. For the absence of doubt, NCR shall not be liable to Teradata or any member of the Teradata Group for any failure of any determination under this Section 4.08 to be accurate under applicable Tax Law.

Section 5. Tax Payments.

Section 5.01 Payment of Taxes With Respect to Tax Returns Reflecting Taxes of the Other Company. In the case of any Tax Return reflecting Taxes allocated hereunder to the Company that is not the Responsible Company:

(a) Computation and Payment of Tax Due. At least three Business Days prior to any Payment Date for any Tax Return, the Responsible Company shall compute the amount of Tax required to be paid to the applicable Tax Authority (taking into account the requirements of Section 4.04 relating to consistent accounting practices) with respect to such Tax Return on such Payment Date. The Responsible Company shall pay such amount to such Tax Authority on or before such Payment Date (and provide notice and proof of payment to the other Company).

(b) Computation and Payment of Liability With Respect To Tax Due. Within 30 days following the earlier of (i) the due date (including extensions) for filing any such Tax Return (excluding any Tax Return with respect to payment of estimated Taxes or Taxes due with a request for extension of time to file) or (ii) the date on which such Tax Return is filed, if NCR is the Responsible Company, then Teradata shall pay to NCR the amount allocable to the Teradata Group under the provisions of Section 2, and if Teradata is the Responsible Company, then NCR shall pay to Teradata the amount allocable to the NCR Group under the provisions of Section 2, in each case, plus interest computed at the Prime Rate on the amount of the payment based on the number of days from the earlier of (A) the due date of the Tax Return (including extensions) or (B) the date on which such Tax Return is filed, to the date of payment.

(c) Adjustments Resulting in Underpayments. In the case of any adjustment pursuant to a Final Determination with respect to any such Tax Return, the Responsible Company shall pay to the applicable Tax Authority when due any additional Tax due with respect to such Return required to be paid as a result of such adjustment pursuant to a Final Determination. The Responsible Company shall compute the amount attributable to the Teradata Group in accordance with Section 2 and Teradata shall pay to NCR any amount due NCR (or NCR shall pay Teradata any amount due Teradata) under Section 2 within 30 days from the later of (i) the date the additional Tax was paid by the Responsible Company or (ii) the date of receipt of a written notice and demand from the Responsible Company for payment of the amount due, accompanied by evidence of payment and a statement detailing the Taxes paid and describing in reasonable detail the particulars relating thereto. Any payments required under this Section 5.01(c) shall include interest computed at the Prime Rate based on the number of days from the date the additional Tax was paid by the Responsible Company to the date of the payment under this Section 5.01(c).

Section 5.02 Indemnification Payments.

All indemnification payments under this Agreement shall be made by NCR directly to Teradata and by Teradata directly to NCR; provided, however, that if the Companies mutually agree with respect to any such indemnification payment, any member of the NCR Group, on the one hand, may make such indemnification payment to any member of the Teradata Group, on the other hand, and vice versa.

Section 6. Tax Benefits.

Section 6.01 Tax Refunds in General. Except as set forth below, NCR shall be entitled to any refund (and any interest thereon received from the applicable Tax Authority) of Taxes for which NCR is liable hereunder, Teradata shall be entitled to any refund (and any interest thereon received from the applicable Tax Authority) of Taxes for which Teradata is liable hereunder and a Company receiving a refund to which another Company is entitled hereunder shall pay over such refund to such other Company within thirty days after such refund is received (together with interest computed at the Prime Rate based on the number of days from the date the refund was received to the date the refund was paid over).

Section 6.02 Timing Differences and Reverse Timing Differences.

(a) If a member of the Teradata Group actually realizes in cash pursuant to a Final Determination any Tax Benefit as a result of an adjustment pursuant to a Final Determination to any Taxes for which a member of the NCR Group is liable hereunder (or Tax Attribute of a member of the NCR Group) and such Tax Benefit would not have arisen but for such adjustment (determined on a with or without basis), or if a member of the NCR Group actually realizes in cash pursuant to a Final Determination any Tax Benefit as a result of an adjustment pursuant to a Final Determination to any Taxes for which a member of the Teradata Group is liable hereunder (or Tax Attribute of a member of the Teradata Group) and such Tax Benefit would not have arisen but for such adjustment (determined on a with or without basis), Teradata or NCR, as the case may be, shall make a payment to either NCR or Teradata, as appropriate, within 30 days following such actual realization of the Tax Benefit, in an amount equal to such Tax Benefit actually realized in cash (including any Tax Benefit actually realized as a result of the payment), plus interest on such amount computed at the Prime Rate based on the number of days from the date of such actual realization of the Tax Benefit to the date of payment of such amount under this Section 6.02(a).

(b) If a member of the Teradata Group actually realizes in cash pursuant to a Final Determination any Tax Detriment as a result of an adjustment pursuant to a Final Determination to any Taxes for which a member of the NCR Group is liable hereunder (or Tax Attribute of a member of the NCR Group) (in such circumstance, NCR being the “Adjusted Party”) and such Tax Detriment would not have arisen but for such adjustment (determined on a with and without basis), or if a member of the NCR Group actually realizes in cash pursuant to a Final Determination any Tax Detriment as a result of an adjustment pursuant to a Final Determination to any Taxes for which a member of the Teradata Group is liable hereunder (or Tax Attribute of a member of the Teradata Group) (in such circumstance, Teradata being the “Adjusted Party”) and such Tax Detriment would not have arisen but for such adjustment (determined on a with and without basis), the Adjusted Party shall make a payment to the other party within 30 days

following the later of such actual realization of the Tax Detriment and the Adjusted Party’s actual realization of the corresponding Tax Benefit, in an amount equal to the lesser of such Tax Detriment actually realized in cash and the Tax Benefit, if any, actually realized in cash by the Adjusted Party pursuant to such adjustment (which would not have arisen but for such adjustment), plus interest on such amount computed at the Prime Rate based on the number of days from the later of the date of such actual realization of the Tax Detriment and the Adjusted Party’s actual realization of the corresponding Tax Benefit to the date of payment of such amount under this Section 6.02(b).

(c) No later than 30 days after a Tax Benefit or Tax Detriment described in Section 6.02(a) or (b) is actually realized in cash by a member of the NCR Group or a member of the Teradata Group, NCR (if a member of the NCR Group actually realizes such Tax Benefit or Tax Detriment) or Teradata (if a member of the Teradata Group actually realizes such Tax Benefit or Tax Detriment) shall provide the other Company with a written calculation of the amount payable pursuant to this Section 6.02. In the event that NCR or Teradata disagrees with any such calculation described in this Section 6.02(c), NCR or Teradata shall so notify the other Company in writing within 30 days of receiving the written calculation set forth above in this Section 6.02(c). NCR and Teradata shall endeavor in good faith to resolve such disagreement.

Section 6.03 Teradata Carrybacks. Teradata shall be entitled to any refund actually received in cash that is attributable to, and would not have arisen but for (determined on a with and without basis), a Teradata Carryback pursuant to the proviso set forth in Section 4.07, provided that the refund is a refund of Taxes for the Tax Period to which the Teradata Carryback is carried or the first or second immediately following Tax Periods. Any such payment of such refund made by NCR to Teradata pursuant to this Section 6.03 shall be recalculated in light of any Final Determination (or any other facts that may arise or come to light after such payment is made, such as a carryback or carryforward of a NCR Group Tax Attribute to a Tax Period in respect of which such refund is received) that would affect the amount to which Teradata is entitled, and an appropriate adjusting payment shall be made by Teradata to NCR such that the aggregate amounts paid pursuant to this Section 6.03 equals such recalculated amount (with interest computed at the Prime Rate).

Section 7. Tax-Free Status.

Section 7.01 Tax Opinions/Rulings and Representation Letters.

Each of Teradata and NCR hereby represents and agrees that (A) it has examined the Ruling Documents and the Representation Letters prior to the date hereof and (B) all information contained in such Ruling Documents or Representation Letters that concerns or relates to such Company or any member of its Group will be true, correct and complete.

Section 7.02 Restrictions on Teradata.

Letters, Ruling Documents or Tax Opinions/Rulings. Teradata agrees that it will not take or fail to take, or permit any Teradata Affiliate to take or fail to take, any action which prevents or could reasonably be expected to prevent (A) the Tax-Free Status, or (B) any transaction contemplated by the Separation and Distribution Agreement which is intended by the parties to be tax-free from so qualifying, including issuing any Teradata Capital Stock that would prevent the Distribution from qualifying as a tax-free distribution within the meaning of Section 355 of the Code.

(b) Teradata agrees that, from the date hereof until the first day after the two-year anniversary of the Closing Date, it will (i) maintain its status as a company whose separate affiliated group, within the meaning of Code Section 355(b)(3), is engaged in the Active Trade or Business and (ii) not engage in any transaction that would result in it ceasing to be a company whose separate affiliated group is so engaged in the Active Trade or Business.

(c) Teradata agrees that, from the date hereof until the first day after the two-year anniversary of the Closing Date, it will not (i) enter into any Proposed Acquisition Transaction or, to the extent Teradata has the right to prohibit any Proposed Acquisition Transaction, permit any Proposed Acquisition Transaction to occur (whether by (a) redeeming rights under a shareholder rights plan, (b) finding a tender offer to be a “permitted offer” under any such plan or otherwise causing any such plan to be inapplicable or neutralized with respect to any Proposed Acquisition Transaction, or (c) approving any Proposed Acquisition Transaction, whether for purposes of Section 203 of the DGCL or any similar corporate statute, any “fair price” or other provision of Teradata’s charter or bylaws or otherwise), (ii) merge or consolidate with any other Person or liquidate or partially liquidate, (iii) in a single transaction or series of transactions sell or transfer (other than sales or transfers of inventory in the ordinary course of business) all or substantially all of the assets that were transferred to Teradata pursuant to the Contribution (or pursuant to the First Contribution) or sell or transfer 60% or more of the gross assets of the Active Trade or Business or 60% or more of the consolidated gross assets of Teradata and its Affiliates (such percentages to be measured based on fair market value as of the Closing Date), (iv) redeem or otherwise repurchase (directly or through a Teradata Affiliate) any Teradata stock, or rights to acquire stock, except to the extent such repurchases satisfy Section 4.05(1)(b) of Revenue Procedure 96-30 (as in effect prior to the amendment of such Revenue Procedure by Revenue Procedure 2003-48), (v) amend its certificate of incorporation (or other organizational documents), or take any other action, whether through a stockholder vote or otherwise, affecting the relative voting rights of Teradata Capital Stock (including, without limitation, through the conversion of any Teradata Capital Stock into another class of Teradata Capital Stock) or (vi) take any other action or actions (including any action or transaction that would be reasonably likely to be inconsistent with any representation made in the Representation Letters, Ruling Documents or the Tax Opinions/Rulings) which in the aggregate (and taking into account any other transactions described in this subparagraph (c)) would be reasonably likely to have the effect of causing or permitting one or more persons (whether or not acting in concert) to acquire directly or indirectly stock representing a Fifty-Percent or Greater Interest in Teradata or otherwise jeopardize the Tax-Free Status, unless prior to taking any such action set forth in the foregoing clauses (i) through (vi), (A) Teradata shall have requested that NCR obtain a supplemental Ruling in accordance with Section 7.03(b) and (d) of this Agreement to the effect that such transaction will not affect the Tax-Free Status and NCR shall have received such a supplemental Ruling in form and substance satisfactory to NCR in its sole and absolute

discretion, which discretion shall be exercised in good faith solely to preserve the Tax-Free Status (and in determining whether such a Ruling is satisfactory, NCR may consider, among other factors, the appropriateness of any underlying assumptions and management’s representations made in connection with such Ruling), or (B) Teradata shall provide NCR with an Unqualified Tax Opinion in form and substance satisfactory to NCR in its sole and absolute discretion, which discretion shall be exercised in good faith solely to preserve the Tax-Free Status (and in determining whether an opinion is satisfactory, NCR may consider, among other factors, the appropriateness of any underlying assumptions and management’s representations if used as a basis for the opinion and NCR may determine that no opinion would be acceptable to NCR) or (C) NCR shall have waived the requirement to obtain such ruling or opinion.

(d) Certain Issuances of Teradata Capital Stock. If Teradata proposes to enter into any Section 7.02(d) Acquisition Transaction or, to the extent Teradata has the right to prohibit any Section 7.02(d) Acquisition Transaction, proposes to permit any Section 7.02(d) Acquisition Transaction to occur, in each case, during the period from the date hereof until the first day after the two-year anniversary of the Closing Date, Teradata shall provide NCR, no later than ten days following the signing of any written agreement with respect to the Section 7.02(d) Acquisition Transaction, with a written description of such transaction (including the type and amount of Teradata Capital Stock to be issued in such transaction) and a certificate of the Board of Directors of Teradata to the effect that the Section 7.02(d) Acquisition Transaction is not a Proposed Acquisition Transaction or any other transaction to which the requirements of Section 7.02(c) apply (a “Board Certificate”).

(e) Distributions by Foreign Teradata Subsidiaries. Until January 1^st of the calendar year immediately following the calendar year in which the Distribution occurs, Teradata shall neither cause nor permit any foreign subsidiary of Teradata to enter into any transaction or take any action that would be considered under the Code to constitute the declaration or payment of a dividend (including pursuant to Section 304 of the Code) without obtaining the prior written consent of NCR (such prior written consent not to be unreasonably withheld).

Section 7.03 Procedures Regarding Opinions and Rulings.

(a) If Teradata notifies NCR that it desires to take one of the actions described in clauses (i) through (vi) of Section 7.02(c) (a “Notified Action”), NCR and Teradata shall reasonably cooperate to attempt to obtain the ruling or opinion referred to in Section 7.02(c), unless NCR shall have waived the requirement to obtain such ruling or opinion.

(b) Rulings or Unqualified Tax Opinions at Teradata’s Request. NCR agrees that at the reasonable request of Teradata pursuant to Section 7.02(c), NCR shall cooperate with Teradata and use its reasonable best efforts to seek to obtain, as expeditiously as possible, a supplemental Ruling from the IRS or an Unqualified Tax Opinion for the purpose of permitting Teradata to take the Notified Action. In no event shall NCR be required to file any Ruling Request under this Section 7.03(b) unless Teradata represents that (A) it has read the Ruling Request, and (B) all information and representations, if any, relating to any member of the Teradata Group, contained in the Ruling Request documents are (subject to any qualifications therein) true, correct and complete.

(c) Rulings or Unqualified Tax Opinions at NCR’s Request. NCR shall have the right to obtain a supplemental Ruling or an Unqualified Tax Opinion at any time in its sole and absolute discretion. If NCR determines to obtain a supplemental Ruling or an Unqualified Tax Opinion, Teradata shall (and shall cause each Affiliate of Teradata to) cooperate with NCR and take any and all actions reasonably requested by NCR in connection with obtaining the Ruling or Unqualified Tax Opinion (including, without limitation, by making any representation or reasonable covenant or providing any materials or information requested by the IRS or Tax Advisor; provided that Teradata shall not be required to make (or cause any Affiliate of Teradata to make) any representation or covenant that is inconsistent with historical facts or as to future matters or events over which it has no control). NCR and Teradata shall each bear its own costs and expenses in obtaining a Ruling or an Unqualified Tax Opinion requested by NCR.

(a) Notwithstanding anything in this Agreement or the Separation and Distribution Agreement to the contrary, Teradata shall be responsible for, and shall indemnify and hold harmless NCR and its Affiliates and each of their respective officers, directors and employees from and against, one hundred percent (100%) of any Tax-Related Losses that are attributable to or result from any one or more of the following: (A) the acquisition of all or a portion of the stock or assets of any member of the Teradata Group by any means whatsoever by any Person, (B) any negotiations, understandings, agreements or arrangements by Teradata with respect to transactions or events (including, without limitation, stock issuances, pursuant to the exercise of stock options or otherwise, option grants, capital contributions or acquisitions, or a series of such transactions or events) that cause the Distribution to be treated as part of a plan pursuant to which one or more Persons acquire directly or indirectly stock of Teradata representing a Fifty-Percent or Greater Interest therein, (C) any action or failure to act by Teradata after the Distribution (including, without limitation, any amendment to Teradata’s certificate of incorporation (or other organizational documents), whether through a stockholder vote or otherwise) affecting the relative voting rights of Teradata stock (including, without limitation, through the conversion of any Teradata Capital Stock into another class of Teradata Capital Stock), (D) any act or failure to act by Teradata or any Teradata Affiliate described in

Section 7.02 (regardless whether such act or failure to act is covered by a Ruling, Unqualified Tax Opinion or waiver described in clause (A), (B) or (C) of Section 7.02(c), a Board Certificate described in Section 7.02(d) or a consent described in Section 7.02(f)) or (E) any breach by Teradata of its agreement and representation set forth in Section 7.01.

(b) For purposes of calculating the amount and timing of any Tax-Related Loss for which Teradata is responsible under this Section 7.04, Tax-Related Losses shall be calculated by assuming that NCR, the NCR Affiliated Group and each member of the NCR Group (I) pay Tax at the highest marginal corporate Tax rates in effect in each relevant taxable year and (II) have no Tax Attributes in any relevant taxable year.

(c) Teradata shall not be entitled to any refund (or any interest thereon received from the applicable Tax Authority) of Taxes for which Teradata is responsible under this Section 7.04, and Section 6.02 shall not apply to any Tax Benefit that NCR realizes as a result of an adjustment to any Taxes for which a member of the Teradata Group is responsible under this Section 7.04.

(d) Teradata shall pay NCR the amount of any Tax-Related Losses for which Teradata is responsible under this Section 7.04: (A) in the case of Tax-Related Losses described in clause (i) of the definition of Tax-Related Losses no later than two Business Days prior to the date NCR files, or causes to be filed, the applicable Tax Return for the year of the Distribution (the “Filing Date”) (provided that if such Tax-Related Losses arise pursuant to a Final Determination described in clause (a), (b) or (c) of the definition of “Final Determination”, then Teradata shall pay NCR no later than two Business Days after the date of such Final Determination with interest calculated at the Prime Rate plus two percent, compounded semiannually, from the date that is two Business Days prior to the Filing Date through the date of such Final Determination) and (B) in the case of Tax-Related Losses described in clause (ii) or (iii) of the definition of Tax-Related Losses, no later than two Business Days after the date NCR pays such Tax-Related Losses.

personnel reasonably required as witnesses or for purposes of providing information or documents in connection with any administrative or judicial proceedings relating to Taxes.

(b) Any information or documents provided under this Section 8 shall be kept confidential by the Company receiving the information or documents, except as may otherwise be necessary in connection with the filing of Tax Returns or in connection with any administrative or judicial proceedings relating to Taxes.

In addition, in the event that NCR determines that the provision of any information to Teradata or any Teradata Affiliate could be commercially detrimental, violate any law or agreement or waive any Privilege, the parties shall use reasonable best efforts to permit compliance with its obligations under this Section 8 in a manner that avoids any such harm or consequence.

Section 8.02 Income Tax Return Information. Teradata and NCR acknowledge that time is of the essence in relation to any request for information, assistance or cooperation made by NCR or Teradata pursuant to Section 8.01 or this Section 8.02. Teradata and NCR acknowledge that failure to conform to the deadlines set forth herein or reasonable deadlines otherwise set by NCR or Teradata could cause irreparable harm.

(a) Each Company shall provide to the other Company information and documents relating to its Group required by the other Company to prepare Tax Returns. Any information or documents the Responsible Company requires to prepare such Tax Returns shall be provided in such form as the Responsible Company reasonably requests and in sufficient time for the Responsible Company to file such Tax Returns on a timely basis.

(b) At Teradata’s sole expense, Teradata shall provide to NCR the information reasonably requested in writing by NCR in connection with the preparation of Tax Returns in accordance with the deadlines set forth in such written request.

(c) In the event that Teradata fails to provide any information requested by NCR pursuant to Section 8.01 or this Section 8.02, within the deadlines as set forth herein (or otherwise reasonably set by NCR and agreed to by Teradata, such agreement not to be unreasonably withheld), NCR shall have the right to engage a nationally recognized public accounting firm of its choice (the “Accountant”), in its sole and absolute discretion, to gather such information directly from Teradata or any other members of the Teradata Group. Teradata and all members of the Teradata Group agree, upon ten Business Days’ notice by NCR, in the case of a failure by Teradata to provide information pursuant to Section 8.01 or this Section 8.02, to permit any such Accountant full access to all records or other information requested by such Accountant that are in the possession of Teradata or any member of the Teradata Group during

reasonable business hours. Teradata agrees promptly to pay NCR all reasonable costs and expenses incurred by NCR in connection with the engagement of such Accountant.

Section 8.03 Reliance. If any member of one Group (the “Supplier Group”) supplies information to a member of the other Group (the “Signing Group”) in connection with a Tax liability and an officer of a member of the Signing Group signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then upon the written request of such member of the Signing Group identifying the information being so relied upon, the chief financial officer of the Supplier Group (or any officer of the Supplier Group as designated by the chief financial officer of the Supplier Group) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete. The Company that is a member of the Supplier Group agrees to indemnify and hold harmless each member of the Signing Group and its directors, officers and employees from and against any fine, penalty, or other cost or expense of any kind attributable to a member of the Supplier Group having supplied, pursuant to this Section 8, a member of the Signing Group with inaccurate or incomplete information in connection with a Tax liability.

Section 9. Tax Records.

Section 9.01 Retention of Tax Records. Each Company shall preserve and keep all Tax Records exclusively relating to the assets and activities of its Group for Pre-Closing Periods (and the portion, ending on the Closing Date, of any Tax Period that includes but does not end on the Closing Date), and NCR shall preserve and keep all other Tax Records relating to Taxes of the Groups for Pre-Closing Periods until the earlier of (i) the expiration of any applicable statutes of limitation, and (ii) seven years after the Closing Date. After such earlier date, each Company may dispose of such records upon 90 days’ prior written notice to the other Company. If, prior to the expiration of the applicable statute of limitation or such seven-year period, a Company reasonably determines that any Tax Records which it would otherwise be required to preserve and keep under this Section 9 are no longer material in the administration of any matter under the Code or other applicable Tax Law and the other Company agrees, then such first Company may dispose of such records upon 90 days’ prior notice to the other Company. Any notice of an intent to dispose given pursuant to this Section 9.01 shall include a list of the records to be disposed of describing in reasonable detail each file, book, or other record accumulation being disposed. The notified Company shall have the opportunity, at its cost and expense, to copy or remove, within such 90-day period, all or any part of such Tax Records.

Section 13. Treatment of Payments; Tax Gross Up.

Section 13.01 Treatment of Tax Indemnity and Tax Benefit Payments. In the absence of any change in Tax treatment under the Code or other applicable Tax Law:

(a) any Tax indemnity payments made by a Company under Section 5 shall be reported for Tax purposes by the payor and the recipient as distributions or capital contributions, as appropriate, occurring immediately before the Closing (but only to the extent the payment does not relate to a Tax allocated to the payor in accordance with Section 1552 of the Code or the regulations thereunder or Treasury Regulation Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or as payments of an assumed or retained liability, and

(b) any Tax Benefit payments made by a Company under Section 6, shall be reported for Tax purposes by the payor and the recipient as distributions or capital contributions, as appropriate, occurring immediately before the Closing (but only to the extent the payment does not relate to a Tax allocated to the payor in accordance with Section 1552 of the Code or the regulations thereunder or Treasury Regulation Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or as payments of an assumed or retained liability.

Section 13.02 Tax Gross Up. If, notwithstanding the manner in which Tax indemnity payments and Tax Benefit payments were reported, there is an adjustment to the Tax liability of a Company as a result of its receipt of a payment pursuant to this Agreement, such payment shall be appropriately adjusted so that the amount of such payment, reduced by the amount of all income Taxes payable with respect to the receipt thereof (but taking into account all correlative Tax Benefits resulting from the payment of such income Taxes), shall equal the amount of the payment which the Company receiving such payment would otherwise be entitled to receive pursuant to this Agreement.

Section 13.03 Interest Under This Agreement. Anything herein to the contrary notwithstanding, to the extent one Company (“Indemnitor”) makes a payment of interest to another Company (“Indemnitee”) under this Agreement with respect to the period from the date that the Indemnitee made a payment of Tax to a Tax Authority to the date that the Indemnitor reimbursed the Indemnitee for such Tax payment, the interest payment shall be treated as interest expense to the Indemnitor (deductible to the extent provided by law) and as interest income by the Indemnitee (includible in income to the extent provided by law). The amount of the payment shall not be adjusted under Section 13.02 to take into account any associated Tax Benefit to the Indemnitor or Tax Detriment to the Indemnitee.

Section 14. Disagreements. The Companies mutually desire that collaboration will continue between them. Accordingly, they will try, and they will cause their respective Group members to try, to resolve in an amicable manner all disagreements and misunderstandings connected with their respective rights and obligations under this Agreement, including any amendments hereto. In furtherance thereof, in the event of any dispute or disagreement (other than a High-Level Dispute) (a “Tax Arbitrator Dispute”) between the Companies as to the interpretation of any provision of this Agreement or

the performance of obligations hereunder, the Tax departments of the Companies shall negotiate in good faith to resolve the Tax Arbitrator Dispute. If such good faith negotiations do not resolve the Tax Arbitrator Dispute, then the matter, upon written request of either Company, will be referred to a tax lawyer or accountant acceptable to each of the Companies (the “Tax Arbitrator”). The Tax Arbitrator may, in its discretion, obtain the services of any third-party appraiser, accounting firm or consultant that the Tax Arbitrator deems necessary to assist it in resolving such disagreement. The Tax Arbitrator shall furnish written notice to the Companies of its resolution of any such Tax Arbitrator Dispute as soon as practical, but in any event no later than 45 days after its acceptance of the matter for resolution. Any such resolution by the Tax Arbitrator will be conclusive and binding on the Companies. Following receipt of the Tax Arbitrator’s written notice to the Companies of its resolution of the Tax Arbitrator Dispute, the Companies shall each take or cause to be taken any action necessary to implement such resolution of the Tax Arbitrator. In accordance with Section 16, each Company shall pay its own fees and expenses (including the fees and expenses of its representatives) incurred in connection with the referral of the matter to the Tax Arbitrator. All fees and expenses of the Tax Arbitrator in connection with such referral shall be shared equally by the Companies. Any High-Level Dispute shall be resolved pursuant to the procedures set forth in Article VIII of the Separation and Distribution Agreement. Nothing in this Section 14 will prevent either Company from seeking injunctive relief if any delay resulting from the efforts to resolve the Tax Arbitrator Dispute through the Tax Arbitrator (or any delay resulting from the efforts to resolve any High-Level Dispute through the procedures set forth in Article VIII of the Separation and Distribution Agreement) could result in serious and irreparable injury to either Company.

Section 15. Late Payments. Any amount owed by one party to another party under this Agreement which is not paid when due shall bear interest at the Prime Rate plus 2% percent, compounded semiannually, from the due date of the payment to the date paid. To the extent interest required to be paid under this Section 15 duplicates interest required to be paid under any other provision of this Agreement, interest shall be computed at the higher of the interest rate provided under this Section 15 or the interest rate provided under such other provision.

Section 16. Expenses. Except as otherwise provided in this Agreement, each party and its Affiliates shall bear their own expenses incurred in connection with preparation of Tax Returns, Tax Contests, and other matters related to Taxes under the provisions of this Agreement.

Section 17. Dual Consolidated Losses.

Section 17.01 General. Through the taxable year 2006, the NCR Group has made the election provided in Treasury Regulation Sections 1.1503-2(g)(2)(i) and 1.1503-2T(g)(2)(i) with respect to dual consolidated losses for the separate units identified on Schedule 1. In the taxable year that includes the External Spin-Off, the NCR Group may make an election provided under either Treasury Regulation Section 1.1503-2(g)(2)(i) or Treasury Regulation Section 1.1503(d)-6(d) with respect to dual consolidated losses for the separate units identified on Schedule 2 (the separate units identified on Schedules 1 or 2 shall be referred to as the “Separate Units”). In connection with the Internal Spin-Off and

External Spin-Off certain assets and liabilities of these Separate Units were or will be transferred to the Teradata Group.

Section 17.02 Teradata Elections, Reporting Requirements and Triggering Events. The Teradata Group shall retain the assets and liabilities of the Separate Units within its consolidated group, make the election provided in connection with the multiple-party exception of Treasury Regulation Section 1.1503(d)-6(f)(2)(i) and file the required agreements pursuant to Treasury Regulation Section 1.1503-2(g)(2)(i) (the “New (g)(2) Agreements”) as provided for under Treasury Regulation Section 1.1503(d)-8(b)(4). If the NCR Group elects to apply Treasury Regulation Sections 1.1503(d)-1 through 1.1503(d)-8 for the taxable year that includes the External Spin-Off, the Teradata Group shall make the election provided in connection with the multiple-party exception of Treasury Regulation Section 1.1503(d)-6(f)(2)(i) and file any required agreement pursuant to Treasury Regulation Section 1.1503(d)-6(f)(2)(iii) (the “New Domestic Use Agreements”). The New (g)(2) Agreements and New Domestic Use Agreements shall cover and certify the entire amount of the loss previously certified by the NCR Group for each year and each Separate Unit. The Teradata Group (with assistance and cooperation from NCR) shall comply with all applicable reporting requirements contained in Treasury Regulation Sections 1.1503-2, 1.1503-2T and 1.1503(d)-1 through 1.1503(d)-8 with respect to the dual consolidated losses of the Separate Units certified by the NCR Group for each taxable year up to and including the taxable year that includes the External Spin-Off. No member of the Teradata Group shall cause, through action or inaction, a triggering event as defined in Treasury Regulation Sections 1.1503-2(g)(2)(iii)(A) or 1.1503(d)-6(e) with respect to the dual consolidated losses previously certified by the NCR Group for the Separate Units that results in any member of the NCR Group having to recapture a dual consolidated loss or otherwise being held liable for such recapture amount.

Section 17.03 NCR Reporting Requirements and Triggering Events. The NCR Group (with assistance and cooperation from Teradata) shall comply with all applicable reporting requirements contained in Treasury Regulation Sections 1.1503-2, 1.1503-2T and 1.1503(d)-1 through 1.1503(d)-8 with respect to the dual consolidated losses of the Separate Units certified by the NCR Group for each taxable year up to and including the taxable year that includes the External Spin-Off. No member of the NCR Group shall cause, through action or inaction, a triggering event as defined in Treasury Regulation Sections 1.1503-2(g)(2)(iii)(A) or 1.1503(d)-6(e) with respect to the dual consolidated losses previously certified by the NCR Group for the Separate Units that results in any member of the Teradata Group having to recapture a dual consolidated loss or otherwise being held liable for such recapture amount.
