Provided that you comply with your obligations under this Agreement, and subject to its terms and conditions, the Company will provide you with the separation benefits described below:

1.		a.		You will receive severance pay (“Severance”) in an amount equal to one year (52 weeks) of your current annual base salary, which equates to the aggregate gross amount of $362,000.00. Subject to the effectiveness and your non-revocation of the release contained in Sections 11 and 12 of this Agreement, and your compliance with the remainder of the provisions of this Agreement, your Severance will be paid in one lump sum within 30 days following the Effective Date by direct deposit (unless you have previously notified the Company in writing that you wish to be paid by check mailed to your home address). Your Severance will be the exclusive payment that you will receive from the Company in connection with your separation from service and you agree that it is paid in lieu of any other severance pay you might have received from the Company, including, but not limited to, payments pursuant to the Interactive Data Corporation Severance Plan or the terms of your offer letter dated as of May 25, 2006 (the “Prior Agreement”). Your Severance is intended to constitute a “separation pay plan” for purposes of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”).

In the event you die after the Effective Date and before you have received payment of the full amount of your Severance, your beneficiary (as designated by you for purposes of your Company basic group life insurance or, if you have made no such designation or the designated person is no longer living, your estate) will receive your Severance.
		d.		Except as otherwise expressly provided for in the applicable plan documents or in this Agreement, your employee participation in the Company’s employee benefit plans will end on the Effective Date. Your employee group health coverage (as applicable, medical, dental, vision) (your “Group Health Coverage”) will continue through the last day of the month in which the Effective Date falls. Thereafter, you will have the

				right to elect to continue your Group Health Coverage pursuant to COBRA. You may also be eligible to continue to contribute to your Medical Reimbursement Account for a period of time pursuant to COBRA. Information about COBRA will be provided to you separately. If you elect and qualify for COBRA coverage, the Company will continue to pay the employer portion of the applicable premiums (to the extent it is doing so for active employees at the time in question) until the earlier to occur of: September 30, 2010 or the date on which you become eligible for coverage under another group medical plan. You will be obligated to pay your share of premiums, deductibles and co-payments, as applicable from time to time. You are responsible for contacting the Company’s COBRA Administrator to arrange for payment of your portion of the monthly premiums and for making timely payments. You agree that you will promptly notify the Company in writing when you become eligible for coverage under another group medical plan.
		e.		Short-term and long-term disability coverage will cease as of the Effective Date. Basic life insurance and basic accidental death and dismemberment coverage will cease as of the Effective Date. Any spouse or dependent life insurance or supplemental life and accident insurance coverage will cease as of the Effective Date. To the extent available and subject to the terms of the applicable insurance contracts, you may elect to convert coverage to individual policies at your expense.
		f.		The Company will pay you for any salary you are due for the period from the Company’s last regular payroll date through the Effective Date on its first regular payroll date after the Effective Date and will provide you with payment for any accrued and unused Paid Time Off (“PTO”) at the same time. You will accrue no further PTO after the Effective Date.
		g.		Business accident insurance, worker’s compensation insurance coverage, and short-term salary continuation coverage will cease as of the Effective Date. Subject to the provisions of Section 1(d) above, your participation in the Medical and Dependent Care Reimbursement Account (if applicable) will cease as of the Effective Date. Any funds held in your Medical or Dependent Care Reimbursement Account will be treated in accordance with the terms and conditions of the applicable plan.
		h.		You will retain ownership of your vested account balance under the Xxxxxxx 401(k) Retirement Plan and the Xxxxxxx 401(k) Excess Plan in accordance with the terms of those plans.
		i.		Options to purchase shares of Interactive Data Corporation common stock, if any, that were granted to you and that have vested prior to or vest on the Effective Date may be exercised in accordance with the terms of the Company’s 2000 Long-Term Incentive Plan, as amended (“LTIP”), the related summary of grant award and the related option grant certificate (collectively, the “Option Documents”).

15. By signing this Agreement, you acknowledge that you have read this Agreement carefully and understand all its terms. Further, you acknowledge that you are entering into this Agreement voluntarily and of your own free will, after having had the opportunity to discuss it with an attorney. In signing this Agreement, you confirm that no representative of the Company or Group has made to you, and that you are not relying on, any promise, oral or written, relating to your employment, the termination of your employment, the term of any severance agreement, or any other related matter that is not reflected in this Agreement.

16. You understand and agree that other than receiving the payments and benefits provided for in this Agreement, you will receive no further payment or benefit from the Company or the Group.

17. This Agreement, the Option Documents, the RSU Documents and the Proprietary Information & Inventions Agreement executed by you on June 2, 2006 represent the entire Agreement between you and the Group concerning its subject matters and supersede and replace any express or implied prior agreement between you and the Company on the same subject matters, including, without limitation, the Prior Agreement. This Agreement may be amended only by a written document signed by the parties hereto.

18. The laws of the Commonwealth of Massachusetts applicable to contracts to be executed, and to entirely performed therein, will govern the construction and interpretation of this Agreement.

19. Any payments made or benefits provided to you under this Agreement will be reduced by all applicable withholding taxes and any other applicable deductions.

20. The failure of any party to this Agreement to enforce any of its terms, provisions or covenants shall not be construed as a waiver of the same or of the right of such party to enforce the same. Waiver by any party hereto of any breach or default by another party of any term or provision of this Agreement shall not operate as a waiver of any other breach or default. In the event that any one or more of the provisions of this Agreement is held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remainder of the Agreement shall not in any way be affected or impaired thereby, or, if any of the provisions contained in this Agreement are held to be excessively broad as to duration, activity or subject, such provisions shall be construed by limiting and reducing them so as to be enforceable to the maximum extent allowed by applicable law. In addition, upon a finding by a court (or other tribunal) that the Release in Section 11 above is unenforceable, you agree, upon the request of the Company, promptly to execute a new release as close in scope as possible to the one in Section 11 that is enforceable.
