VALUE ACT CAPITAL MASTER FUND, L.P.

LIMITED GUARANTEE, dated as of March 8, 2007 (this “Limited Guarantee”), by ValueAct Capital Master Fund, L.P. (“Guarantor”) in favor of Catalina Marketing Corporation, a Delaware corporation (the “Company”). Any capitalized term not otherwise defined herein shall be as defined in the Merger Agreement (as defined below).

1. LIMITED GUARANTEE. To induce the Company to enter into that certain Agreement of Merger, dated as of the date hereof (as amended, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among the Company, CMC Holdings LLC, a Delaware limited liability company (“Parent”), and Catalina Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub,” and together with Parent, the “Parent Parties”), the Guarantor absolutely, unconditionally and irrevocably guarantees to the Company, on the terms and conditions set forth herein, the due, punctual and complete payment and performance, if and when due, of (i) 100% of Parent's payment obligation with respect to the Parent Termination Fee pursuant to and only in accordance with Section 7.3(d) of the Merger Agreement and any additional amounts that may become due pursuant to Section 7.3(e) of the Merger Agreement, and (ii) any other obligations of Parent under the Merger Agreement as a result of a breach thereof by Parent or Merger Sub (the payment obligations referred to above (collectively, the “Obligations”); provided that the maximum aggregate amount payable by the Guarantor under this Limited Guarantee (exclusive of the reimbursement of costs and expenses, if applicable, pursuant to and only in accordance with Section 16 hereof (such payment, if and only if required to be paid by Guarantor in accordance with the terms hereof, the “Prevailing Party Costs”)) shall not exceed the aggregate of $50,640,000 U.S. Dollars (the “Cap”), it being understood that this Limited Guarantee may not be enforced without giving effect to the Cap. Except for Prevailing Party Costs, the Company hereby agrees that in no event shall the Guarantor be required to pay to any Person under, in respect of, or in connection with this Limited Guarantee, more than the Cap, and that Guarantor shall not have any obligation or liability to any Person relating to, arising out of or in connection with, this Limited Guarantee or the Merger Agreement other than as expressly set forth herein. All sums payable by the Guarantor hereunder shall be made in immediately available funds. The Company may, in its sole discretion, bring and prosecute a separate action or actions against the Guarantor for the full payment of the Obligations, subject to the Cap (plus any Prevailing Party Costs), regardless of whether the action is brought against one or both of the Parent Parties or whether one or both of the Parent Parties is joined in any such action or actions.

NATURE OF LIMITED GUARANTEE.

(a) The Company shall not be obligated to file any claim relating to the Obligations in the event that one or both of the Parent Parties becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of the Company to so file shall not affect the Guarantor’s obligations hereunder. In the event that any payment to the Company in respect of the Obligations is rescinded or must otherwise be returned for any reason whatsoever, the Guarantor shall remain liable hereunder with respect to the Obligations (plus any Prevailing Party Costs) as if such payment had not been made (subject to the terms hereof). This is an

unconditional guarantee of payment and not of collectibility. Notwithstanding any other provision of this Limited Guarantee, the Company hereby agrees that (i) the Guarantor may assert, as a defense to any payment or performance by the Guarantor under this Limited Guarantee, any defense to such payment or performance that Parent or Merger Sub could assert against the Company under the terms of the Merger Agreement, other than any such defense exclusively arising out of, due to, or as a result of, the insolvency or bankruptcy of Parent or Merger Sub and (ii) to the extent Parent and Merger Sub are relieved by the parties to the Merger Agreement (including the Company) of their obligations under Section 7.3(d) of the Merger Agreement, the Guarantor shall be similarly relieved of its Obligations under this Limited Guarantee.

(b) The Company hereby acknowledges and agrees that, as of the date hereof, each of Parent’s and Merger Sub’s sole assets are a de minimis amount of cash and their respective rights under the Merger Agreement, and that no additional funds or assets are expected to be contributed to Parent or Merger Sub unless and until the Closing occurs.

(c) Notwithstanding anything that may be expressed or implied in this Limited Guarantee or any document or instrument delivered contemporaneously herewith, and notwithstanding the fact that the Guarantor may be a limited partnership, by its acceptance of the benefits of this Limited Guarantee, the Company covenants and agrees that (1) neither the Company nor any of its Subsidiaries or Affiliates, and the Company agrees to the maximum extent permitted by Legal Requirement, none of its officers, directors, security holders or representatives, has or shall have any right of recovery under or in connection with the Merger Agreement or the transactions contemplated thereby or otherwise relating thereto, and to the extent that it has or obtains any such right, it, to the maximum extent permitted by Legal Requirement, hereby waives (on its own behalf and on behalf of each of the aforementioned persons) each and every such right against, and hereby releases, and no personal liability shall attach to, the Guarantor or any of the Sponsor Affiliates (as defined below), from and with respect to any claim, known or unknown, now existing or hereafter arising, in connection with any transaction contemplated by or otherwise relating to the Merger Agreement or the transactions contemplated thereby, whether by or through attempted piercing of the limited liability company veil, by or through a claim by or on behalf of Parent or Merger Sub (or any other Person) against any Sponsor Affiliate (including, without limitation, a claim to enforce the Equity Commitment Letter, by the enforcement of any assessment or by any legal or equitable proceeding, by virtue of any statute, regulation or applicable Legal Requirement, or otherwise) (the “Released Claims”), except for its rights to recover from the Guarantor (but not any Sponsor Affiliate (including, without limitation, any general partner or managing member)) under and to the extent provided in this Limited Guarantee (subject to the limitations described herein); and (2) recourse against the Guarantor under this Limited Guarantee (subject to the limitations described herein) shall be the sole and exclusive remedy of the Company and all of its Subsidiaries and Affiliates against the Guarantor and each Sponsor Affiliate in respect of any liabilities or obligations arising under, or in connection with, the Merger Agreement or the transactions contemplated thereby or otherwise relating thereto. For purposes of this Limited Guarantee, "Sponsor Affiliate" means, collectively, any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder, Affiliate (other than Parent or Merger Sub) or assignee of the undersigned or any Sponsor Affiliate or any former, current or future director, officer, employee, agent, general or limited partner, manager,

member, stockholder, Affiliate (other than Parent or Merger Sub) or assignee of any of the foregoing.

(d) The Company hereby covenants and agrees that it shall not institute, directly or indirectly, and shall cause its Subsidiaries and Affiliates not to institute, in the name of or on behalf of the Company or any other Person, any proceeding or bring any other claim arising under, or in connection with, the Merger Agreement or the transactions contemplated thereby or otherwise relating thereto, against the Guarantor or the Sponsor Affiliates except for claims against the Guarantor under this Limited Guarantee (subject to the limitations described herein).

(e) The Company acknowledges that the Guarantor is agreeing to enter into this Limited Guarantee in reliance on the provisions set forth in Sections 2(b) through (e). Section 2(b), 2(c), 2(d) and 2(e) shall survive termination of this Limited Guarantee.

3. CHANGES IN OBLIGATIONS; CERTAIN WAIVERS. The Guarantor agrees that the Company may at any time and from time to time, without notice to or further consent of the Guarantor, extend the time of payment of any of the Obligations, and also may make any agreement with one or both of the Parent Parties for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any agreement between the Company, on the one hand, and one or both of the Parent Parties, on the other hand, without in any way impairing or affecting the Guarantor’s obligations under this Limited Guarantee. The Guarantor agrees that the obligations of the Guarantor hereunder shall not be released or discharged, in whole or in part, or otherwise affected by: (a) the failure of the Company to assert any claim or demand or to enforce any right or remedy against one or both of the Parent Parties or any Other Guarantor; (b) any change in the time, place or manner of payment of any of the Obligations or any rescission, waiver, compromise, consolidation or other amendment or modification of any of the terms or provisions of the Merger Agreement or any other agreement evidencing, securing or otherwise executed in connection with any of the Obligations (provided that any such change, rescission, waiver, compromise, consolidation or other amendment or modification shall be subject to the prior written consent of the Parent Parties to the extent expressly required by the Merger Agreement); (c) the addition, substitution or release of any Person interested in the transactions contemplated by the Merger Agreement (provided, that any such addition, substitution or release shall be subject to the prior written consent of the Parent Parties to the extent expressly required under the Merger Agreement); (d) any change in the corporate or limited liability company existence, structure or ownership of one or both of the Parent Parties or any other Person liable with respect to any of the Obligations; (e) any insolvency, bankruptcy, reorganization or other similar proceeding affecting one or both of the Parent Parties, or any other Person liable with respect to any of the Obligations; (f) subject to the last sentence of Section 2(a) hereof, any lack of validity or enforceability of the Merger Agreement or any agreement or instrument relating thereto; (g) the existence of any claim, set-off or other rights which the Guarantor may have at any time against one or both of the Parent Parties or the Company, whether in connection with the Obligations or otherwise; or (h) the adequacy of any other means the Company may have of obtaining payment of any of the Obligations. To the fullest extent permitted by Legal Requirement, the Guarantor hereby expressly waives any and all rights or defenses arising by reason of any Legal Requirement which would otherwise require any election of remedies by the Company. The Guarantor waives promptness, diligence, notice of the acceptance of this Limited

Guarantee and of the Obligations, presentment, demand for payment, notice of non-performance, default, dishonor and protest, notice of any Obligations incurred and all other notices of any kind (except for notices to be provided to the Parent Parties and Dechert LLP in accordance with Section 8.9 of the Merger Agreement), all defenses which may be available by virtue of any valuation, stay, moratorium or other similar Legal Requirement now or hereafter in effect, any right to require the marshalling of assets of one or both of the Parent Parties, or any other Person liable with respect to any of the Obligations, and all suretyship defenses generally (other than breach by the Company of this Limited Guarantee). The Guarantor hereby unconditionally and irrevocably agrees that it shall not institute, and shall cause its Affiliates not to institute, any proceeding asserting that this Limited Guarantee is illegal, invalid or unenforceable in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general application relating to or affecting creditors’ rights, and general equitable principles (whether considered in a proceeding in equity or at law). The Guarantor acknowledges that it will receive substantial direct and indirect benefits from the transactions contemplated by the Merger Agreement and that the waivers set forth in this Limited Guarantee are knowingly made in contemplation of such benefits and after the advice of counsel.

4. NO SUBROGATION. The Guarantor hereby unconditionally and irrevocably waives and agrees not to exercise any rights that it may now have or hereafter acquire against one or both of the Parent Parties or any other Person liable with respect to any of the Obligations that arise from the existence, payment, performance, or enforcement of the Guarantor’s obligations under or in respect of this Limited Guarantee or any other agreement in connection therewith, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Company against one or both of the Parent Parties or any other Person interested in the transactions contemplated by the Merger Agreement liable with respect to any of the Obligations, whether or not such claim, remedy or right arises in equity or under contract or any applicable Legal Requirement, including, without limitation, the right to take or receive from one or both of the Parent Parties or any other Person liable with respect to any of the Obligations, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Obligations and Prevailing Party Costs, if applicable, shall have been irrevocably paid in full in cash; provided that, the Guarantor shall have the right to cause any other Person to satisfy its payment obligations to the Company under Section 1 hereof; provided, however, that such right in the preceding proviso shall only relieve the Guarantor of its obligation to make such payment when such payment is irrevocably paid by such other Person in full in cash. If any amount shall be paid to the Guarantor in violation of the immediately preceding sentence at any time prior to the payment in full in cash of the Obligations and Prevailing Party Costs, if applicable, such amount shall be received and held in trust for the benefit of the Company, shall be segregated from other property and funds of the Guarantor and shall forthwith be paid or delivered to the Company in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the Obligations and Prevailing Party Costs, if applicable,, whether matured or unmatured, or to be held as collateral for any Obligations or Prevailing Party Costs, if applicable, thereafter arising.

5. NO WAIVER; CUMULATIVE RIGHTS. No failure on the part of the Company to exercise, and no delay in exercising, any right, remedy or power hereunder, shall operate as a waiver thereof, nor shall any single or partial exercise by the Company of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or power hereunder. Each and every right, remedy or power hereby granted to the Company or allowed pursuant to any applicable Legal Requirement shall be cumulative and not exclusive of any other, and may be exercised by the Company at any time or from time to time. The Company shall not have any obligation to proceed at any time or in any manner against, or exhaust any or all of the Company’s rights against, the Parent Parties or any other Person liable for the Obligations prior to proceeding against Guarantor.
