PREPARATION AND FILING OF TAX RETURNS

Section 2.01 Compuware’s Responsibility. Subject to the other applicable provisions of this Agreement, Compuware shall have sole and exclusive responsibility for the preparation and filing of:

(a) all Consolidated Returns and all Combined Returns for any taxable period;

(b) all Income Tax Returns (other than Consolidated Returns and Combined Returns) with respect to Compuware and/or any Compuware Affiliate for any taxable period;

(c) all Income Tax Returns (other than Consolidated Returns and Combined Returns) with respect to Covisint and/or any Covisint Affiliate that are required to be filed (taking into account any extension of time that has been requested or received) on or prior to the IPO Date; and

(d) all Non-Income Tax Returns with respect to Compuware, any Compuware Affiliate, or the Compuware Business or any part thereof for any taxable period.

Section 2.02 Covisint’s Responsibility. Subject to the other applicable provisions of this Agreement, Covisint shall have sole and exclusive responsibility for the preparation and filing of:

(a) all Income Tax Returns (other than Consolidated Returns and Combined Returns) with respect to Covisint and/or any Covisint Affiliate that are required to be filed (taking into account any extension of time that has been requested or received) after the IPO Date; and

(b) all Non-Income Tax Returns with respect to Covisint, any Covisint Affiliate, or the Covisint Business or any part thereof for any taxable period; provided that Covisint acknowledges that Compuware prepared and filed such returns that were required to be filed (taking into account any extension of time that has been requested or received) before the Effective Date.

Subject to the other applicable provisions of this Agreement, Covisint hereby irrevocably designates, and agrees to cause each Covisint Affiliate to so designate, Compuware as its sole

and exclusive agent and attorney-in-fact to take such action (including execution of documents) as Compuware, in its sole discretion, may deem appropriate in any and all matters (including Audits) relating to any Tax Return described in Section 2.01.

Section 2.03 Manner of Tax Return Preparation.

(a) Unless otherwise required by a Taxing Authority or by applicable law, the Parties hereby agree to prepare and file all Tax Returns, and to take all other actions, in a manner consistent with (1) this Agreement, (2) any Tax Opinion, (3) any Supplemental Tax Opinion, (4) any Ruling, and (5) any Supplemental Ruling. All Tax Returns shall be filed on a timely basis (taking into account applicable extensions) by the Party responsible for filing such returns under this Agreement.

(b) Compuware shall have the exclusive right, in its sole discretion, with respect to any Tax Return described in Section 2.01, to determine (1) the manner in which such Tax Return shall be prepared and filed, including the elections, method of accounting, positions, conventions and principles of taxation to be used and the manner in which any Tax Item shall be reported, (2) whether any extensions shall be requested, (3) the elections that will be made by Compuware, any Compuware Affiliate, Covisint, and/or any Covisint Affiliate on such Tax Return, (4) whether any amended Tax Returns shall be filed, (5) whether any claims for refund shall be made, (6) whether any refunds shall be paid by way of refund or credited against any liability for the related Tax, and (7) whether to retain outside firms to prepare and/or review such Tax Returns; provided, however, that Compuware shall consult with Covisint prior to changing any method of accounting if such action would solely impact Covisint or Covisint Affiliates. In the case of any Consolidated Return or Combined Return with respect to a Straddle IPO Period or a Post-IPO Period that reports a Covisint Separate Tax Liability or Covisint Separate Tax Assets or Taxes related to the Covisint Business in excess of Two Hundred Fifty Thousand Dollars ($250,000), Compuware shall provide to Covisint a pro forma draft of the portion of such Tax Return that reflects the Covisint Separate Tax Liability or Covisint Separate Tax Assets or Taxes related to the Covisint Business at least twenty-one (21) days prior to the due date (with applicable extensions) for the filing of such Tax Return for Covisint’s review and comment. Covisint shall provide its comments to Compuware at least ten (10) days prior to the due date (with applicable extensions) for the filing of such Tax Return. In the case of a dispute regarding the reporting of any Tax Item on such Tax Return or the requesting of a change of method of accounting that would solely impact Covisint or Covisint Affiliates, which the Parties cannot resolve, Compuware and Covisint shall jointly retain a nationally recognized accounting firm that is mutually agreed upon by Compuware and Covisint (the “Independent Accountant”) to determine whether the proposed reporting of Compuware or Covisint is more appropriate. If Compuware and Covisint are unable to agree, the Independent Accountant shall be Deloitte Tax LLP. The relevant Tax Item shall be reported in the manner that the Independent Accountant determines is more appropriate, and such determination shall be final and binding on Compuware and Covisint. If Covisint has not provided its comments on the pro forma draft of the portion of the Tax Return, or in the case of a dispute regarding the reporting of any Tax Item, such dispute has not been resolved by the due date (with applicable extension) for the filing of any Tax Return, Compuware shall file such Tax Return reporting all Tax Items in the manner as originally set forth on the pro forma draft of the portion of the Tax Return provided to Covisint; provided, however, that

Compuware agrees that it will thereafter file an amended Tax Return, if necessary, reporting any disputed Tax Item in the manner determined by the Independent Accountant, and any other Tax Item as agreed upon by Compuware and Covisint. The fees and expenses incurred in retaining the Independent Accountant shall be borne equally by Compuware and Covisint, except that if the Independent Accountant determines that the proposed reporting of the disputed Tax Item(s) submitted to the Independent Accountant for its determination by a Party is frivolous, has not been asserted in good faith or for which there is not substantial authority, one hundred percent (100%) of the fees and expenses of the Independent Accountant shall be borne by such Party.

(c) Covisint shall timely provide, in accordance with Compuware’s internal tax return calendar, which will be provided to Covisint on a rolling one-year schedule, all information necessary for Compuware to prepare all Tax Returns and compute all estimated Tax payments (for purposes of Section 7.01). If Covisint does not meet these deadlines, the Section 2.03(b) notice period to Covisint shall be waived.

ARTICLE III.

LIABILITY FOR TAXES

Section 3.01 Covisint’s Liability for Taxes. (a) Covisint and each Covisint Affiliate shall be jointly and severally liable for the following Taxes, and shall be entitled to receive and retain all refunds of Taxes previously incurred by Covisint, any Covisint Affiliate, or the Covisint Business with respect to such Taxes:

(a) all Taxes with respect to Tax Returns described in Section 2.01(a) to the extent that such Taxes are related to (i) the Covisint Separate Tax Liability, or (ii) the Covisint Business, for any taxable period or portion thereof beginning on or after the Effective Date;

(b) all Taxes with respect to Tax Returns described in Section 2.01(c);

(d) all Taxes imposed by any Taxing Authority with respect to the Covisint Business, Covisint or any Covisint Affiliate (other than in connection with the required filing of a Tax Return described in Section 2.01(a), Section 2.01(c) or Section 2.02) for any taxable period.

Section 3.02 Compuware’s Liability for Taxes. Compuware shall be liable for the following Taxes, and shall be entitled to receive and retain all refunds of Taxes previously incurred by Compuware, any Compuware Affiliate, or the Compuware Business with respect to such Taxes:

(a) except as provided in Section 3.01(a), all Taxes with respect to Tax Returns described in Section 2.01(a);

(b) all Taxes with respect to Tax Returns described in Section 2.01(b) or Section 2.01(d); and

(c) all Taxes imposed by any Taxing Authority with respect to Compuware, any Compuware Affiliate, or the Compuware Business (other than in connection with the required filing of a Tax Return described in Section 2.01(a), Section 2.01(b) or Section 2.01(d)) for any taxable period.

Section 3.03 Taxes, Refunds and Credits. Notwithstanding Section 3.01 and Section 3.02, (i) Compuware shall be liable for all Taxes incurred by any person with respect to the Compuware Business for all periods and shall be entitled to all refunds and credits of Taxes previously incurred by any person with respect to such Taxes, and (ii) Covisint and each Covisint Affiliate shall be jointly and severally liable for all Taxes incurred by any person with respect to the Covisint Business for all periods and shall be entitled to all refunds and credits of Taxes previously incurred by any person with respect to such Taxes; provided, however, that in the case of Taxes related to the Covisint Business as set forth in Section 3.01(a), Covisint shall only be entitled to refunds to the extent set forth in Section 3.01(a). Nothing in this Agreement shall be construed to require compensation, by payment, credit, offset or otherwise, by Compuware (or any Compuware Affiliate) to Covisint (or any Covisint Affiliate) for any loss, deduction, credit or other Tax attribute arising in connection with, or related to, Covisint, any Covisint Affiliate, or the Covisint Business, that is shown on, or otherwise reflected with respect to, any Tax Return described in Section 2.01; provided, however, that in the event the Covisint Separate Tax Liability with respect to a particular taxable period or portion thereof beginning on or after the Effective Date is less than zero (i.e., the calculation results in Covisint Separate Tax Assets), Compuware shall pay to Covisint an amount equal to the Tax Benefit that the Compuware Group recognizes as a result of the Covisint Separate Tax Liability being less than zero for such taxable period.

Section 3.04 Payment of Tax Liability. If one Party is liable or responsible for Taxes, under Section 3.01 through Section 3.03, with respect to Tax Returns for which another Party is responsible for filing, or with respect to Taxes that are paid by another Party, then the liable or responsible Party shall pay the Taxes (or a reimbursement of such Taxes) to the other Party pursuant to Section 7.05.

Section 3.05 Computation. In the case of any Consolidated Return or Combined Return with respect to a Straddle IPO Period or a Post-IPO Period that reports a Covisint Separate Tax Liability or Covisint Separate Tax Assets or Taxes related to the Covisint Business in excess of Two Hundred Fifty Thousand Dollars ($250,000), Compuware shall provide Covisint with a written calculation in reasonable detail (including, upon reasonable request, copies of all work sheets and other materials used in preparation thereof) setting forth the amount of any Covisint Separate Tax Liability or Covisint Separate Tax Assets or estimated Covisint Separate Tax Liability (for purposes of Section 7.01) and any Taxes related to the Covisint Business. Covisint shall have the right to review and comment on such calculation. Any dispute with respect to such calculation shall be resolved pursuant to Section 10.04; provided, however, that, notwithstanding any dispute with respect to any such calculation, in no event shall any payment attributable to the amount of any Covisint Separate Tax Liability or estimated Covisint Separate Tax Liability be paid later than the date provided in ARTICLE VII.

ARTICLE IV.

DECONSOLIDATION EVENTS

Section 4.01 Tax Allocations. Although, as of the Effective Date, neither Party had any plan or intent to effectuate any transaction that would constitute a Deconsolidation Event, the Parties now anticipate that there will be a Deconsolidation Event on account of a Distribution. Accordingly, the Parties have set forth how certain Tax matters with respect to a Deconsolidation Event would be handled in the event that, as a result of changed circumstances, a transaction that constitutes a Deconsolidation Event is pursued or otherwise occurs at some future time.

(a) Allocation of Tax Items. In the case of a Deconsolidation Event, all Tax computations for (1) any Pre-Deconsolidation Periods or portions thereof ending on the date of the Deconsolidation Event and (2) the immediately following taxable period of Covisint or any Covisint Affiliate, shall be made pursuant to the principles of section 1.1502-76(b) of the Treasury Regulations or of a corresponding provision under the laws of other jurisdictions, as reasonably determined by Compuware, taking into account all reasonable suggestions made by Covisint with respect thereto.

(b) Allocation of Tax Assets. In the case of a Deconsolidation Event, Compuware shall determine the allocation of any Tax Assets among Compuware, each Compuware Affiliate, Covisint, and each Covisint Affiliate and provide Covisint a schedule setting forth the Tax Assets allocated to Covisint and each Covisint Affiliate. Covisint shall have the right to comment on such allocation in the same manner and to the same extent set forth in Section 2.03(b) and any dispute regarding such allocation shall be handled in the same manner as set forth in Section 2.03(b) (provided, however, for purposes of clarity, that such schedule of allocated Tax Assets shall be provided to Covisint without regard to whether such allocated Tax Assets exceed Two Hundred Fifty Thousand Dollars ($250,000)). The Parties hereby agree that in the absence of controlling legal authority or unless otherwise provided under this Agreement, Tax Assets shall be allocated to the legal entity that is required under ARTICLE III to bear the liability for the Tax associated with such Tax Asset, or in the case where no Party is required hereunder to bear such liability, the Party that incurred the cost or burden associated with the creation of such Tax Asset.

Section 4.02 Carrybacks.

(a) In General. In the case of a Deconsolidation Event, Compuware agrees to pay to Covisint the Tax Benefit from the use in any Pre-Deconsolidation Period (the “Carryback Period”) of a carryback of any Tax Asset of Covisint or the Covisint Group from a Post-Deconsolidation Period (other than a carryback of any Tax Asset attributable to Distribution Taxes for which the liability is borne by Compuware or any Compuware Affiliate). If subsequent to the payment by Compuware to Covisint of the Tax Benefit of a carryback of a Tax Asset of Covisint or the Covisint Group, there shall be a Final Determination that results in a decrease (1) to the amount of the Tax Asset so carried back or (2) to the amount of such Tax Benefit, Covisint shall repay to Compuware any amount that would not have been payable to Covisint pursuant to this Section 4.02(a) had the amount of the benefit been determined in light of these events. Nothing in this Section 4.02(a) shall require

Compuware to file an amended Tax Return or claim for refund of Income Taxes; provided, however, that Compuware shall use its reasonable efforts to use any carryback of a Tax Asset of Covisint or the Covisint Group that is carried back under this Section 4.02(a).

(b) Net Operating Losses. In the case of a Deconsolidation Event, notwithstanding any other provision of this Agreement, Covisint hereby expressly agrees to elect (under section 172(b)(3) of the Code or applicable Treasury Regulations and, to the extent feasible, any similar provisions of any state, local or non-U.S. Tax law) to relinquish or cause an election to relinquish to be made for any right to carry back net operating losses of Covisint or the Covisint Group to any Pre-Deconsolidation Periods of Compuware or the Compuware Group (in which event no payment shall be due from Compuware to Covisint in respect of such net operating losses).

Section 4.03 Continuing Covenants. Each of Compuware (for itself and each Compuware Affiliate) and Covisint (for itself and each Covisint Affiliate) agrees (1) not to take any action reasonably expected to result in an increased Tax liability to the other, a reduction in a Tax Asset of the other or an increased liability to the other under this Agreement, and (2) to take any action reasonably requested by the other that would reasonably be expected to result in a Tax Benefit or avoid a Tax Detriment to the other; provided, in either such case, that the taking or refraining to take such action does not result in any additional cost not fully compensated for by the other Party or any other adverse effect to such Party. The Parties hereby acknowledge that the preceding sentence is not intended to limit, and therefore shall not apply to, the rights of the Parties with respect to matters otherwise covered by this Agreement. Covisint further agrees to cooperate in making elections that are reasonably requested by Compuware with respect to any Consolidated Return.

ARTICLE V.

DISTRIBUTION TAXES AND EXCESS LOSS ACCOUNT

Section 5.01 Liability for Distribution Taxes. Although neither Party had any plan or intent to effectuate a Distribution as of the Effective Date, the Parties now anticipate that there will be a Distribution. Accordingly, the Parties have set forth how certain Tax matters with respect to a Distribution would be handled in the event that, as a result of changed circumstances, a Distribution is pursued at some future time.

(a) Compuware’s Liability for Distribution Taxes. In the event of a Distribution, notwithstanding Section 3.01 through Section 3.03, Compuware and each Compuware Affiliate shall be jointly and severally liable for any Distribution Taxes, to the extent that such Distribution Taxes are attributable to, caused by, or result from, one or more of the following:

(i) any action or omission by Compuware (or any Compuware Affiliate) inconsistent with any information, covenant, representation, or material related to Compuware, any Compuware Affiliate, or the Compuware Business in an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling except where such information, covenant, representation, or material was not previously disclosed to Compuware (for the

avoidance of doubt, disclosure of any action or fact that is inconsistent with any information, covenant, representation, or material submitted to Tax Counsel, the IRS, or other Taxing Authority, as applicable, in connection with an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling shall not relieve Compuware (or any Compuware Affiliate) of liability under this Agreement unless such information, covenant, representation, or material was not disclosed to Compuware before such submission);

(ii) any action or omission by Compuware (or any Compuware Affiliate) (including any act or omission that is in furtherance of, connected to, or part of a plan or series of related transactions (within the meaning of section 355(e) of the Code)), including a cessation, transfer to affiliates, or disposition of its active trades or businesses, or a stock buyback or payment of an extraordinary dividend by Compuware (or any Compuware Affiliate) following a Distribution;

(iii) any acquisition of any stock or assets of Compuware (or any Compuware Affiliate) by one or more other persons (other than Covisint or a Covisint Affiliate) prior to or following a Distribution; or

(iv) any issuance of stock by Compuware (or any Compuware Affiliate), or change in ownership of stock in Compuware (or any Compuware Affiliate).

(b) Covisint’s Liability for Distribution Taxes. In the event of a Distribution, notwithstanding Section 3.01 through Section 3.03, Covisint and each Covisint Affiliate shall be jointly and severally liable for any Distribution Taxes, to the extent that such Distribution Taxes are attributable to, caused by, or result from, one or more of the following:

(i) any action or omission by Covisint (or any Covisint Affiliate) after a Distribution at any time, that is inconsistent with any information, covenant, representation, or material related to Covisint, any Covisint Affiliate, or the Covisint Business in an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling except where such information, covenant, representation, or material was not previously disclosed to Covisint (for the avoidance of doubt, disclosure by Covisint (or any Covisint Affiliate) to Compuware (or any Compuware Affiliate) of any action or fact that is inconsistent with any information, covenant, representation, or material submitted to Tax Counsel, the IRS, or other Taxing Authority, as applicable, in connection with an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling shall not relieve Covisint (or any Covisint Affiliate) of liability under this Agreement unless such information, covenant, representation, or material was not disclosed to Covisint before such submission);

(ii) any action or omission by Covisint (or any Covisint Affiliate) after the date of a Distribution (including any act or omission that is in furtherance of, connected to, or part of a plan or series of related transactions (within the meaning of

section 355(e) of the Code) occurring on or prior to the date of a Distribution) including a cessation, transfer to affiliates or disposition of the active trades or businesses of Covisint (or any Covisint Affiliate), stock buyback or payment of an extraordinary dividend;

(iii) any acquisition of any stock or assets of Covisint (or any Covisint Affiliate) by one or more other persons (other than Compuware or any Compuware Affiliate) prior to or following a Distribution; or

(iv) any issuance of stock by Covisint (or any Covisint Affiliate) after a Distribution, including any issuance pursuant to the exercise of employee stock options or other employment related arrangements or the exercise of warrants, or change in ownership of stock in Covisint (or any Covisint Affiliate) after a Distribution.

(c) Joint Liability for Remaining Distribution Taxes. Compuware shall be liable for fifty percent (50%) and Covisint and each Covisint Affiliate shall be jointly and severally liable for fifty percent (50%), of any Distribution Taxes not otherwise allocated by Section 5.01(a) or Section 5.01(b).

Section 5.02 Continuing Covenants.

(a) Covisint Restrictions. Covisint agrees that, so long as a Distribution could, in the reasonable discretion of Compuware, be effectuated, Covisint will not knowingly take or fail to take, or permit any Covisint Affiliate to knowingly take or fail to take, any action that could reasonably be expected to preclude Compuware’s ability to effectuate a Distribution. In the event of a Distribution, Covisint agrees that (1) it will take, or cause any Covisint Affiliate to take, any action reasonably requested by Compuware in order to enable Compuware to effectuate a Distribution and (2) it will not take or fail to take, or permit any Covisint Affiliate to take or fail to take, any action where such action or failure to act would be inconsistent with any information, covenant, representation, or material that relates to facts or matters related to Covisint (or any Covisint Affiliate) or within the control of Covisint and is contained in an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling (except where such information, covenant, representation, or material was not previously disclosed to Covisint) other than as permitted by Section 5.02(c). For this purpose an action is considered inconsistent with a representation if the representation states that there is no plan or intention to take such action. In the event of a Distribution, Covisint agrees that it will not take (and it will cause the Covisint Affiliates to refrain from taking) any position on a Tax Return that is inconsistent with such Distribution qualifying under section 355 of the Code.

(b) Compuware Restrictions. In the event of a Distribution, Compuware agrees that it will not take or fail to take, or permit any Compuware Affiliate to take or fail to take, any action where such action or failure to act would be inconsistent with any material, information, covenant or representation that relates to facts or matters related to Compuware (or any Compuware Affiliate) or within the control of Compuware and is contained in an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling. For this purpose an action is considered inconsistent with a representation if the representation states that there is no plan

or intention to take such action. In the event of a Distribution, Compuware agrees that it will not take (and it will cause the Compuware Affiliates to refrain from taking) any position on a Tax Return that is inconsistent with such Distribution qualifying under section 355 of the Code.

(c) Certain Covisint Actions Following a Distribution. In the event of a Distribution, Covisint agrees that, during the two (2) year period following a Distribution, without first obtaining, at Covisint’s own expense, either a supplemental opinion from Tax Counsel that such action will not result in Distribution Taxes (a “Supplemental Tax Opinion”) or a Supplemental Ruling that such action will not result in Distribution Taxes, unless in any such case Compuware and Covisint agree otherwise, neither Covisint nor any Covisint Affiliate shall (1) sell all or substantially all of the assets of Covisint or any Covisint Affiliate or approve or allow the discontinuance, cessation, or sale or other transfer (to an Affiliate or otherwise) of, or a material change in, the business conducted by Covisint or any Covisint Affiliate as of the date of the Distribution, (2) merge or consolidate Covisint or any Covisint Affiliate with another entity, without regard to which Party is the surviving entity or liquidate or partially liquidate, (3) transfer any assets of Covisint in a transaction described in section 351 of the Code (other than a transfer to a corporation that files a Consolidated Return with Covisint and that is wholly-owned, directly or indirectly, by Covisint) or subparagraph (C) or (D) of section 368(a)(1) of the Code, (4) issue stock of Covisint or any Covisint Affiliate (or any instrument that is convertible or exchangeable into any such stock) in an acquisition or public or private offering, (5) facilitate or otherwise participate in any acquisition of stock in Covisint that would result in any shareholder owning five percent (5%) or more of the outstanding stock of Covisint, (6) amend its articles of incorporation (or other organizational documents), or take any other action or approve or allow the taking of any action, whether through a shareholder vote or otherwise, affecting the voting rights of the stock of such party, (7) purchase, directly or through any Affiliate, any of its outstanding stock after the Distribution, other than through stock purchases meeting the requirements of section 4.05(1)(b) of Revenue Procedure 96-30 (without regard to the effect of Revenue Procedure 2003-48 thereon), (8) approve or allow payment of any extraordinary distributions with respect to, or redemptions of shares of any of, Covisint or a Covisint Affiliate, or (9) take any action or permit any of its Affiliates to take any action that, in the aggregate (taking into account other transactions described in this Section 5.02(c)) would be reasonably likely to jeopardize the tax-free status of the Distribution under section 355 of the Code (including under section 355(d) or section 355(e) of the Code). Covisint (or any Covisint Affiliate) shall only undertake any of such actions after Compuware’s receipt of such Supplemental Tax Opinion or Supplemental Ruling and pursuant to the terms and conditions of any such Supplemental Tax Opinion or Supplemental Ruling or as otherwise consented to in writing in advance by Compuware. The Parties hereby agree that they will act in good faith to take all reasonable steps necessary to amend this Section 5.02(c), from time to time, by mutual agreement, to (i) add certain actions to the list contained herein, or (ii) remove certain actions from the list contained herein, in either case, in order to reflect any relevant change in law, regulation or administrative interpretation occurring after the date of this Agreement.

(d) Notice of Specified Transactions. Not later than twenty (20) days prior to entering into any oral or written contract or agreement, and not later than five (5) days after it first becomes aware of any negotiations, plan or intention (regardless of whether it is a Party

to such negotiations, plan or intention), regarding any of the transactions described in paragraph (c), Covisint shall provide written notice of its intent to consummate such transaction or the negotiations, plan or intention of which it becomes aware, as the case may be, to Compuware.

(e) Covisint Cooperation. Covisint agrees that, at the request of Compuware, Covisint shall cooperate fully with Compuware to take any action necessary or reasonably helpful to effectuate a Distribution, including seeking to obtain, as expeditiously as possible, a Tax Opinion, Supplemental Tax Opinion, Ruling, and/or Supplemental Ruling. Such cooperation shall include the execution of any documents that may be necessary or reasonably helpful in connection with obtaining any Tax Opinion, Supplemental Tax Opinion, Ruling, and/or Supplemental Ruling (including any (i) power of attorney, (ii) Officer’s Certificate, (iii) Ruling Documents, (iv) Supplemental Ruling Documents, and/or (v) reasonably requested written representations confirming that (a) Covisint has read the Officer’s Certificate, Ruling Documents, and/or Supplemental Ruling Documents and (b) all information and representations, if any, relating to Covisint, any Covisint Affiliate or the Covisint Business contained therein are true, correct and complete in all material respects).

(f) Earnings and Profits. Compuware will advise Covisint in writing of the decrease in Compuware earnings and profits attributable to a Distribution under section 312(h) of the Code on or before the first anniversary of a Distribution; provided, however, that Compuware shall provide Covisint with estimates of such amounts (determined in accordance with past practice) prior to such anniversary as reasonably requested by Covisint.

Section 5.03 Excess Loss Account. In the event of a Distribution, notwithstanding Section 3.01 through Section 3.03, if the amount of any excess loss account (as defined in sections 1.1502-19(a) and 1.1502-32(a)(3)(ii) of the Treasury Regulations) in the stock of Covisint or any member of the Covisint Group is required for any reason to be included in the consolidated federal taxable income of Compuware or the Compuware Group, Covisint shall pay to Compuware the amount of any Income Tax liability resulting from such inclusion (including, for purposes of clarity, any Income Tax liability resulting from the receipt of a payment under this Section 5.03) (“Excess Loss Account Tax Liability”); provided that the amount of the Excess Loss Account Tax Liability that Covisint is required to pay to Compuware pursuant to this Section 5.03 shall not exceed the aggregate amount of payments that Compuware has previously paid to Covisint for Tax Benefits recognized on account of Covisint Separate Tax Assets pursuant to Section 3.03. The computation of such Excess Loss Account Tax Liability shall be made in accordance with the computational procedures of Section 3.05.

ARTICLE VI.

INDEMNIFICATION

Section 6.01 In General. Compuware and each member of the Compuware Group shall jointly and severally indemnify Covisint, each Covisint Affiliate, and their respective directors, officers and employees, and hold them harmless from and against any and all Taxes or Tax deficiencies for which Compuware or any Compuware Affiliate is liable under this Agreement and any loss, cost, damage or expense, including reasonable attorneys’ fees and costs, that are attributable to, or results from, the failure of Compuware, any Compuware

Affiliate or any director, officer or employee to make any payment required to be made under this Agreement. Covisint and each member of the Covisint Group shall jointly and severally indemnify Compuware, each Compuware Affiliate, and their respective directors, officers and employees, and hold them harmless from and against any and all Taxes or Tax deficiencies for which Covisint or any Covisint Affiliate is liable under this Agreement and any loss, cost, damage or expense, including reasonable attorneys’ fees and costs, that is attributable to, or results from, the failure of Covisint, any Covisint Affiliate or any director, officer or employee to make any payment required to be made under this Agreement.

Section 6.02 Inaccurate, Incomplete or Untimely Information. Compuware and each member of the Compuware Group shall jointly and severally indemnify Covisint, each Covisint Affiliate, and their respective directors, officers and employees, and hold them harmless from and against any loss, cost, damage, fine, penalty, or other expense of any kind attributable to the failure or negligence of Compuware or any Compuware Affiliate in supplying Covisint or any Covisint Affiliate with inaccurate, incomplete or untimely information, in connection with the preparation of any Tax Return. Covisint and each member of the Covisint Group shall jointly and severally indemnify Compuware, each Compuware Affiliate, and their respective directors, officers and employees, and hold them harmless from and against any loss, cost, damage, fine, penalty, or other expense of any kind attributable to the failure or negligence of Covisint or any Covisint Affiliate in supplying Compuware or any Compuware Affiliate with inaccurate, incomplete or untimely information, in connection with the preparation of any Tax Return.

Section 6.03 No Indemnification for Tax Items. Nothing in this Agreement shall be construed as a guarantee of the existence or amount of any loss, credit, carryforward, basis or other Tax Item, whether past, present or future, of Compuware, any Compuware Affiliate, Covisint or any Covisint Affiliate. In addition, for the avoidance of doubt, for purposes of determining any amount owed between the Parties hereto, all such determinations shall be made without regard to any financial accounting tax asset or liability or other financial accounting items.

ARTICLE VII.

PAYMENTS

Section 7.01 Estimated Tax Payments. Not later than three (3) days prior to each Estimated Tax Installment Date with respect to a taxable period for which a Consolidated Return or a Combined Return will be filed, Covisint shall pay to Compuware on behalf of the Covisint Group an amount equal to the amount of any estimated Excess Loss Account Tax Liability (if Compuware has provided written notice to Covisint setting forth such estimated Excess Loss Account Tax Liability as set forth below in this Section 7.01) and any estimated Covisint Separate Tax Liability that Covisint otherwise would have been required to pay to a Taxing Authority on such Estimated Tax Installment Date. Not later than seven (7) days prior to each such Estimated Tax Installment Date, Compuware shall provide Covisint with a written notice setting forth the amount payable by Covisint in respect of any estimated Excess Loss Account Tax Liability (if then reasonably determinable, and if not then reasonably determinable, then as soon as reasonably practicable thereafter) and such estimated Covisint Separate Tax Liability and a calculation of such amounts.

Section 7.02 True-Up Payments. Not later than ten (10) business days after receipt of any Excess Loss Account Tax Liability computation pursuant to Section 5.03 or Covisint Separate Tax Liability computation pursuant to Section 3.05, Covisint shall pay to Compuware, or Compuware shall pay to Covisint, as appropriate, an amount equal to the difference, if any, between (i) the sum of any Excess Loss Account Tax Liability and the Covisint Separate Tax Liability with respect to such period and (ii) the aggregate amount paid by Covisint with respect to such period under Section 7.01.

Section 7.03 Redetermination Amounts. In the event of a redetermination of any Tax Item reflected on any Consolidated Return or Combined Return (other than Tax Items relating to Distribution Taxes), as a result of a refund of Taxes paid, a Final Determination or any settlement or compromise with any Taxing Authority that in any such case would affect the Excess Loss Account Tax Liability or the Covisint Separate Tax Liability, Compuware shall prepare a revised pro forma Tax Return in accordance with Section 2.03(b) (but without regard to whether the Excess Loss Account Tax Liability or Covisint Separate Tax Liability exceeds the threshold dollar amount set forth in Section 2.03(b)) for the relevant taxable period reflecting the redetermination of such Tax Item as a result of such refund, Final Determination, settlement or compromise. Covisint shall pay to Compuware, or Compuware shall pay to Covisint, as appropriate, an amount equal to the difference, if any, between the Excess Loss Account Tax Liability or Covisint Separate Tax Liability, as applicable, reflected on such revised pro forma Tax Return and the Excess Loss Account Tax Liability or Covisint Separate Tax Liability, as applicable, for such period as originally computed pursuant to this Agreement.

Section 7.04 Payments of Refunds, Credits and Reimbursements. If one Party receives a refund or credit of any Tax to which the other Party is entitled pursuant to Section 3.03, the Party receiving such refund or credit shall pay to the other Party the amount of such refund or credit pursuant to Section 7.05. If one Party pays a Tax with respect to which the other Party is liable or responsible pursuant to Section 3.01 through Section 3.03, then the liable or responsible Party shall pay to the other Party the amount of such Tax pursuant to Section 7.05.

Section 7.05 Payments Under This Agreement. In the event that one Party (the “Owing Party”) is required to make a payment to another Party (the “Owed Party”) pursuant to this Agreement, then such payments shall be made according to this Section 7.05. For purposes of this Agreement, and solely with respect to periods prior to a Distribution, a “payment” by an Owing Party to an Owed Party shall be treated as having been made upon an offset of intercompany account(s) of amounts otherwise owing by the Owed Party to the Owing Party in accordance with the Parties’ general practice of offsetting intercompany account(s); provided that the Owing Party shall provide prompt notice of such offset to the Owed Party with sufficient detail of the intercompany account(s) being offset.

(a) In General. All payments shall be made to the Owed Party or to the appropriate Taxing Authority as specified by the Owed Party within the time prescribed for payment in this Agreement, or if no period is prescribed, within ten (10) days after delivery of written notice of payment owing together with a computation of the amounts due.

(b) Treatment of Payments. Unless otherwise required by any Final Determination, the Parties agree that any payments made by one Party to another Party pursuant to this Agreement (other than (i) payments of interest pursuant to Section 7.05(e) and (ii) payments of After-Tax Amounts pursuant to Section 7.05(d)) shall be treated for all Tax and financial accounting purposes as nontaxable payments (dividend distributions or capital contributions, as the case may be) made immediately prior to the Deconsolidation Event and, accordingly, as not includible in the taxable income of the recipient or as deductible by the payor.

(c) Prompt Performance. All actions required to be taken (including payments) by any Party under this Agreement shall be performed within the time prescribed for performance in this Agreement, or if no period is prescribed, such actions shall be performed promptly.

(d) After-Tax Amounts. If pursuant to a Final Determination it is determined that the receipt or accrual of any payment made under this Agreement (other than payments of interest pursuant to Section 7.05(e)) is subject to any Tax, the Party making such payment shall be liable for (i) the After-Tax Amount with respect to such payment and (ii) interest at the rate described in Section 7.05(e) on the amount of such Tax from the date such Tax accrues through the date of payment of such After-Tax Amount. A Party making a demand for a payment pursuant to this Agreement and for a payment of an After-Tax Amount with respect to such payment shall separately specify and compute such After-Tax Amount. However, a Party may choose not to specify an After-Tax Amount in a demand for payment pursuant to this Agreement without thereby being deemed to have waived its right subsequently to demand an After-Tax Amount with respect to such payment.

(e) Interest. Payments pursuant to this Agreement that are not made within the period prescribed in this Agreement (the “Payment Period”) shall bear interest for the period from and including the date immediately following the last date of the Payment Period through and including the date of payment at a per annum rate equal to the prime rate as published in The Wall Street Journal on the last day of such Payment Period. Such interest will be payable at the same time as the payment to which it relates and shall be calculated on the basis of a year of three hundred sixty-five (365) days and the actual number of days for which due.

TAX PROCEEDINGS

Section 8.01 In General. Except as otherwise provided in this Agreement, (i) with respect to Tax Returns described in Section 2.01(a), Section 2.01(b), or Section 2.01(d), Compuware and (ii) with respect to Tax Returns described in Section 2.01(c) or Section 2.02, Covisint (in either case, the “Controlling Party”), shall have the exclusive right, in its sole discretion, to control, contest, and represent the interests of Compuware, any Compuware Affiliate, Covisint, and/or any Covisint Affiliate in any Audit relating to such Tax Return and to resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of any such Audit. The Controlling Party’s rights shall extend to any matter pertaining to the management and control of an Audit, including execution of waivers, choice of forum, scheduling of conferences and the resolution of any Tax Item. Any costs incurred in handling, settling, or contesting an Audit shall be borne by the Controlling Party.

Section 8.02 Participation of Non-Controlling Party. Except as otherwise provided in Section 8.04, the non-Controlling Party shall have control over decisions to resolve, settle or otherwise agree to any deficiency, claim or adjustment with respect to any Sole Responsibility Item (other than any Sole Responsibility Item with respect to Taxes for which Covisint and each Covisint Affiliate are jointly and severally liable under Section 3.01(a), in which case Covisint shall have the right to participate in, but not control, the Audit solely with respect to such Sole Responsibility Item). Except as otherwise provided in Section 8.04, the Controlling Party and the non-Controlling Party shall have joint control over decisions to resolve, settle or otherwise agree to any deficiency, claim or adjustment with respect to any Joint Responsibility Item (other than any Sole Responsibility Item with respect to Taxes for which Covisint and each Covisint Affiliate are jointly and severally liable under Section 3.01(a), in which case Covisint shall have the right to participate in, but not have joint control, the Audit solely with respect to such Sole Responsibility Item). Except as otherwise provided in Section 8.04, the Controlling Party shall not settle any Audit it controls concerning a Tax Item on a basis that would reasonably be expected to adversely affect the non-Controlling Party by at least Fifty Thousand Dollars ($50,000) without obtaining such non-Controlling Party’s consent, which consent shall not be unreasonably withheld, conditioned or delayed if failure to consent would adversely affect the Controlling Party.

Section 8.03 Notice. Within ten (10) business days after a Party becomes aware of the existence of a Tax issue that may give rise to an indemnification obligation under this Agreement, such Party shall give prompt notice to the other Party of such issue (such notice shall contain factual information, to the extent known, describing any asserted tax liability in reasonable detail), and shall promptly forward to the other Party copies of all notices and material communications with any Taxing Authority relating to such issue. Notwithstanding any provision in Section 10.17 to the contrary, if a Party fails to provide the other Party notice as required by this Section 8.03, and the failure results in a detriment to the other Party then any amount that the other Party is otherwise required to pay pursuant to this Agreement shall be reduced by the amount of such detriment.

Section 8.04 Control of Distribution Tax Proceedings. In the event of a Distribution, Compuware shall have the exclusive right, in its sole discretion, to control, contest, and represent the interests of Compuware, any Compuware Affiliate, Covisint, and/or any Covisint Affiliate in any Audits relating to Distribution Taxes and to resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of any such Audit; provided, however, that Compuware shall not settle any such audit with respect to Distribution Taxes with a Taxing Authority that would reasonably be expected to result in a material Tax cost to Covisint or any Covisint Affiliate, without the prior consent of Covisint, which consent shall not be unreasonably withheld, conditioned or delayed. Compuware’s rights shall extend to any matter pertaining to the management and control of such Audit, including execution of waivers, choice of forum, scheduling of conferences and the resolution of any Tax Item; provided, however, that to the extent that Covisint is obligated to bear at least fifty percent (50%) of the liability for any Distribution Taxes under Section 5.01, Compuware and Covisint shall have joint control over decisions to resolve, settle or otherwise agree to any deficiency, claim or adjustment]. Covisint may assume sole control of any Audits relating to Distribution Taxes if it acknowledges in writing that it has sole liability for any Distribution Taxes under Section 5.01 that might arise in such Audit and can demonstrate to the reasonable satisfaction of Compuware that it can satisfy its liability for any such Distribution Taxes. If Covisint is unable to demonstrate to the reasonable satisfaction of Compuware that it will be able to satisfy its liability for such Distribution Taxes, but acknowledges in writing that it has sole liability for any Distribution Taxes under Section 5.01, Covisint and Compuware shall have joint control over the Audit.

Section 9.01(b) and Section 9.01(c) shall continue to apply to Covisint Compensation Items other than Retained Covisint Compensation Items. The Parties hereto agree (i) to report all Tax deductions with respect to Retained Covisint Compensation Items consistently with this Section 9.02(a), to the extent permitted by the Tax law and (ii) that such Tax deductions shall not be considered Tax deductions of Covisint or any Covisint Affiliate for purposes of computing the Covisint Separate Tax Liability or Covisint Separate Tax Assets or Taxes related to the Covisint Business.

(b) If Section 9.02(a) applies, then Compuware shall make a payment or payments to Covisint in an amount equal to 50% of the Tax Benefit realized by Compuware with respect to Retained Covisint Compensation Items at the time that such Tax Benefit is realized; provided that Compuware shall be obligated to make a payment or payments to Covisint under this Section 9.02(b) only if such Tax Benefits are realized on or before the date of any Distribution.

If Compuware does not obtain such a private letter ruling on or before the extended due date for the federal income tax return for the taxable year ending March 31, 2015, then this Section 9.02 shall not apply.

Section 9.03 Notices, Withholding, Reporting. Compuware shall promptly notify Covisint of any post-Deconsolidation Event action giving rise to income to any Covisint Employee or Former Covisint Employee in connection with Covisint Compensation Items related to Options, stock, performance share units, or, options under employee stock purchase

plans, in each case with respect to Compuware stock, if Compuware has knowledge of such action. If required by the Tax law, Covisint shall withhold applicable Taxes and satisfy applicable Tax reporting obligations in connection therewith. If Section 9.01(c) applies, then Covisint shall promptly notify Compuware of any post-Deconsolidation Event action giving rise to income to any Covisint Employee or Former Covisint Employee in connection with Covisint Compensation Items related to Compuware Options, Compuware stock, Compuware performance share units, or, options under Compuware’s employee stock purchase plans, if Covisint has knowledge of such action. If required by the Tax law, Compuware shall withhold applicable Taxes and satisfy applicable Tax reporting obligations in connection therewith. If Section 9.02 above applies, then Covisint shall promptly notify Compuware of any post-Deconsolidation Event action giving rise to income to any Covisint Employee or Former Covisint Employee in connection with Covisint Compensation Items related to Options, stock, performance share units, or, options under employee stock purchase plans granted before the Effective Date, if Covisint has knowledge of such action.

Section 10.03 Cooperation and Exchange of Information.

(a) Cooperation. Covisint and Compuware shall each cooperate fully (and each shall cause its respective Affiliates to cooperate fully) with all reasonable requests from another Party for information and materials not otherwise available to the requesting Party in

connection with the preparation and filing of Tax Returns, claims for refund, and Audits concerning issues or other matters covered by this Agreement or in connection with the determination of a liability for Taxes or a right to a refund of Taxes. Such cooperation shall include:

Section 10.07 Confidentiality and Privileged Matters. Any information exchanged in connection with this Agreement shall be subject to the terms of Sections 5.6 and 5.7 of the Master Separation Agreement.

Section 10.08 Successors. This Agreement shall be binding on and inure to the benefit and detriment of any successor, by merger, acquisition of assets or otherwise, to any of the Parties hereto, to the same extent as if such successor had been an original Party.

Section 10.10 Authorization, Etc. Each of the Parties hereto hereby represents and warrants that it has the power and authority to execute, deliver and perform this Agreement, that this Agreement has been duly authorized by all necessary corporate action on the part of such Party, that this Agreement constitutes a legal, valid and binding obligation of each such Party and that the execution, delivery and performance of this Agreement by such Party does not contravene or conflict with any provision of law or of its charter or bylaws or any agreement, instrument or order binding on such Party.

Section 10.11 Entire Agreement. This Agreement contains the entire agreement among the Parties hereto with respect to the subject matter hereof and supersedes any prior written or oral or contemporaneous written or oral tax sharing agreements or understandings between Compuware (or any Compuware Affiliate) and Covisint (or any Covisint Affiliate) and such prior written or oral or contemporaneous written or oral tax sharing agreements or understandings shall have no further force and effect. If, and to the extent, the provisions of this Agreement conflict with any agreement entered into in connection with a Distribution or Deconsolidation Event, the provisions of this Agreement shall prevail.

Section 10.12 Governing Law and Jurisdiction. This Agreement, including the validity hereof and the rights and obligations of the Parties hereunder, shall be construed in accordance with and shall be governed by the laws of the State of Michigan applicable to contracts made and to be performed entirely in such State (without giving effect to the conflicts of laws provisions thereof).

Section 10.13 Counterparts. This Agreement, including any Schedules hereto and any other documents referred to herein, may be executed in counterparts, each of which shall be deemed to be an original but all of which shall constitute one and the same agreement.

Section 10.14 Binding Effect; Assignment. This Agreement shall inure to the benefit of and be binding upon the Parties hereto and their respective legal representatives and successors, and nothing in this Agreement, express or implied, is intended to confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Agreement. This Agreement may be enforced separately by each member of the Compuware Group and each member of the Covisint Group. Neither Party may assign this Agreement or any rights or obligations hereunder, without the prior written consent of the other Party, and any such assignment shall be void; provided, however, either Party may assign this Agreement to a successor entity formed solely in connection with such Party’s reincorporation in another jurisdiction or into another business form.

Section 10.15 Severability. If any term or other provision of this Agreement or the Schedules attached hereto is determined by a court, administrative agency or arbitrator to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to either Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the fullest extent possible.

Section 10.16 No Third Party Beneficiaries. This Agreement is solely for the benefit of Compuware, the Compuware Affiliates, Covisint and the Covisint Affiliates. This Agreement should not be deemed to confer upon third Parties any remedy, claim, liability, reimbursement, cause of action or other rights in excess of those existing without this Agreement.

Section 10.17 Failure or Indulgence not Waiver; Remedies Cumulative. No failure or delay on the part of either Party hereto in the exercise of any right hereunder shall impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor shall any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement or the Schedules attached hereto are cumulative to, and not exclusive of, any rights or remedies otherwise available.

Section 10.18 Authority. Each of the Parties represent to the other Party that (a) it has the corporate or other requisite power and authority to execute, deliver and perform this Agreement, (b) the execution, delivery and performance of this Agreement by it have been duly authorized by all necessary corporate or other actions, (c) it has duly and validly executed and delivered this Agreement, and (d) this Agreement is its legal, valid and binding obligation, enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and general equity principles.

Section 10.19 Setoff. All payments to be made by any Party under this Agreement may be netted against payments due to such Party under this Agreement or paid through offset of intercompany account(s) as set forth in Section 7.05, but otherwise shall be made without setoff, counterclaim or withholding, all of which are hereby expressly waived.

Section 10.20 Other Remedies. Covisint recognizes that any failure by it or any Covisint Affiliate to comply with its obligations under ARTICLE V would, in the event of a Distribution, result in Distribution Taxes that would cause irreparable harm to Compuware, Compuware Affiliates, and their shareholders. Accordingly, Compuware shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which Compuware is entitled at law or in equity.

Section 10.21 Amendment. This Agreement may only be amended by a written agreement executed by both Parties hereto.

Section 10.22 Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement.

Section 10.23 Interpretation. The headings contained in this Agreement, in any Schedule hereto and in the table of contents to this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Any capitalized term used in any Schedule hereto but not otherwise defined therein, shall have the meaning assigned to such term in this Agreement.

Section 10.24 Incorporation by Reference. All Schedules to this Agreement are incorporated herein by reference and made a part of this Agreement as if set forth in full herein. Any capitalized terms used in any Schedule but not otherwise defined therein shall have the meaning as defined in this Agreement.
