Option Exchange Program

On August 25, 2010, Affinia Group Holdings Inc. (“Holdings”), the direct parent of Affinia Group Intermediate Holdings Inc. (the “Company”), commenced an offer to certain eligible optionholders to exchange their existing options to purchase shares of Holdings common stock for restricted stock unit awards (the “RSUs”) with new vesting terms (the “Option Exchange”). As part of a review of the Company’s executive compensation and employee benefit arrangements on behalf of and under the supervision of the boards of directors of the Company and Holdings, and in light of the economic conditions in which the Company operates, it was determined that offering the RSUs may be better suited than the existing options to meet the Company’s objectives to motivate, retain and reward the eligible optionholders.

Any RSUs granted in connection with the Option Exchange will be governed by the Affinia Group Holdings Inc. 2005 Stock Incentive Plan (the “2005 Stock Plan”) and a new Restricted Stock Unit Award Agreement. In addition, any shares of Holdings common stock acquired upon vesting of the RSUs will be subject to (1) Holdings’ Management Stockholder’s Agreement (the “Stockholders Agreement”), which imposes restrictions on transfers of the shares of Holdings common stock and also provides for various put and call rights with respect to such shares, and which will be amended to implement certain clarifying changes in connection with the Option Exchange, and (2) Holdings’ Sale Participation Agreement (the “Sale Participation Agreement”), which will be amended and restated to clarify that the tag-along rights provided for therein will be applicable to shares of Holdings common stock acquired upon vesting of the RSUs. The current forms of the 2005 Stock Plan, Stockholders Agreement and Sale Participation Agreement have been previously filed by the Company with the SEC.

The RSUs will be subject to performance-based vesting restrictions, which will be modified from the existing performance and time-based vesting restrictions applicable to the currently outstanding options. The RSUs will generally vest if, on or prior to the date on which The Cypress Group L.L.C. and its affiliates (“Cypress”) cease to hold any remaining Holdings common stock, the RSU holder remains employed with Holdings through the date that either:

The RSUs will also vest if either of the performance conditions described above is met within one year (or in the case of our named executive officers for the period of their non-competition obligation, if longer) following a “qualifying termination” of the holder’s employment due to an involuntary termination by Holdings without cause or due to the holder’s death, disability or retirement.

2

Each RSU holder will continue to be subject to the Confidentiality, Non-Competition and Proprietary Information Agreement previously entered into between such holder and Holdings or its affiliates (or an employment agreement containing similar provisions). In the event an RSU holder breaches any of the restrictive covenants regarding confidentiality, proprietary information and a one-year period restricting competition and solicitation of the Company’s clients, customers or employees (or any provision concerning similar matters contained in an employment agreement or other agreement entered into by the RSU holder and Holdings or its affiliates), all outstanding RSUs will be forfeited immediately without consideration.

The deadline for the Option Exchange will be September 22, 2010, unless extended by Holdings. The completion of the Option Exchange is contingent upon eligible optionholders holding at least 70% of eligible options electing to participate in the Option Exchange and a number of other customary conditions. Subject to these conditions, the Option Exchange is expected to be completed in October 2010.
