On August 31, 2010, Salary.com, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Kenexa Corporation, a Pennsylvania corporation (“Kenexa”), and Spirit Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Kenexa (“Purchaser”), pursuant to which, among other things, Purchaser will commence a tender offer for all the outstanding shares of the Company’s common stock, par value $0.0001 per share (the “Shares”), subject to the terms and conditions of the Merger Agreement.

Merger Agreement

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, Purchaser will commence a cash tender offer (the “Offer”) to purchase all of the outstanding Shares, at a purchase price of $4.07 per Share, net to the seller thereof in cash, without interest and less any required withholding taxes (the “Offer Price”). The Offer will remain open for 20 business days from commencement, subject to possible extension on the terms set forth in the Merger Agreement. Pursuant to the Merger Agreement, after the consummation of the Offer, and subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement, Purchaser will be merged with and into the Company (the “Merger”) and the separate corporate existence of Purchaser will cease at that time (the “Effective Time”). Following the consummation of the Merger, the Company will continue as the surviving corporation (the “Surviving Corporation”) and a wholly-owned subsidiary of Kenexa. At the effective time of the Merger, each issued and outstanding Share (other than any Shares owned by Kenexa or Purchaser, any Shares owned by the Company and any Shares owned by stockholders who have properly exercised their statutory rights of appraisal under Section 262 of the Delaware General Corporation Law) will be automatically converted into the right to receive an amount in cash equal to the Offer Price.

The Merger Agreement includes customary representations, warranties and covenants of the Company, Kenexa and Purchaser. The Company has agreed to operate its business in the ordinary course consistent with past practice until the Effective Time. The Company has also agreed (1) to cease all existing, and agreed not to solicit or initiate any additional, discussions with third parties regarding other proposals to acquire the Company and (2) to certain restrictions on its ability to respond to such proposals, subject to fulfillment of certain fiduciary requirements of the Company’s Board of Directors. The Merger Agreement also includes customary termination provisions for both the Company and Kenexa and provides that, in connection with the termination of the Merger Agreement under specified circumstances, the Company may be required to pay Kenexa a termination fee of $3,850,000.

Consummation of the Offer is subject to various conditions, including (1) the valid tender of the number of Shares that would represent at least a majority of the total number of outstanding Shares on a fully diluted basis, where “on a fully diluted basis” means, subject to limited exclusions, the sum of (a) all Shares outstanding plus (b) all Shares the Company may be required to issue pursuant to warrants, options or other obligations outstanding at the expiration date of the Offer under employee stock or similar benefit plans or otherwise, whether or not vested or then exercisable, (2) the expiration or termination of any applicable waiting periods under the U.S. Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and (3) the satisfaction of certain other customary closing conditions.

The parties have agreed that if, following completion of the Offer, Purchaser owns at least 90% of the Shares, the Merger will be completed without a meeting of the Company’s stockholders pursuant to Delaware’s “short-form” merger statute. In furtherance thereof, the Company has granted to Purchaser an option, exercisable in whole but not in part on one occasion, to purchase, at a price per Share equal to the Offer Price, the number of Shares that, when added to the number of Shares owned by Purchaser as of immediately prior to such exercise, will constitute one Share more than 90% of the outstanding Shares “on a fully diluted basis” (assuming the issuance of such Shares).

Under the terms of the Merger Agreement, all stock options outstanding immediately prior to the Effective Time (other than options under the Company’s First Amended and Restated 2004 Stock Option and Incentive Plan (the “2004 Plan”)) that are not then vested and exercisable shall become fully vested and exercisable immediately prior to the Effective Time. Holders of stock options under the 2004 Plan outstanding immediately following the date of the Merger Agreement will be able to exercise such options (including all unvested options, subject to consummation of the Offer) prior to their cancellation as of the consummation of the Offer. All unexercised stock options other than options under the 2004 Plan that are outstanding immediately prior to the Effective Time will be cancelled, and the holders thereof will receive cash (without interest and less any applicable withholding of taxes) equal to the excess, if any, of the Offer Price over the per Share exercise price of the respective options multiplied by the total number of Shares subject to such options. Further, all restricted stock awards and restricted stock units outstanding immediately prior to the Effective Time, will vest in full and will be cancelled immediately prior to the Effective Time and the holders thereof will receive cash equal to the Offer Price multiplied by the total number of Shares underlying such restricted stock awards and restricted stock units, in each case, giving effect to full vesting thereof.

The foregoing summary of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, which is attached as Exhibit 2.1 hereto and incorporated herein by reference.

The Merger Agreement has been attached as an exhibit to provide investors and holders of Shares with information regarding its terms and is not intended to modify or supplement any factual disclosures about Kenexa, Purchaser or the Company in the Company’s public reports filed with the U.S. Securities and Exchange Commission (the “SEC”). The Merger Agreement includes customary representations, warranties and covenants of the Company, Kenexa and Purchaser made to each other as of specific dates and has been negotiated among the parties thereto with the principal purpose of establishing the circumstances in which Kenexa may have the right not to consummate the Offer, or a party may have the right to terminate the Merger Agreement if the representations and warranties of the other party or parties prove to be untrue due to a change in circumstances or otherwise. The assertions embodied in those representations and warranties were made solely for purposes of the contract among the Company, Kenexa and

Purchaser and may be subject to important qualifications and limitations agreed to by such parties in connection with negotiating the Merger Agreement. Moreover, some of those representations, warranties and covenants may not be accurate or complete as of any specified date, may be subject to different contractual standards of materiality or may have been used for the purpose of allocating risk among the Company, Kenexa and Purchaser rather than establishing matters as facts.

Tender and Support Agreement

In order to induce Kenexa and Purchaser to enter into the Merger Agreement, each director and executive officer of the Company entered into a tender and support agreement (the “Tender and Support Agreement”) with Kenexa and Purchaser concurrent with the execution and delivery of the Merger Agreement. Shares held by these directors and officers that are eligible to be tendered into the Offer represent, in the aggregate, approximately 33% of Shares outstanding on the date of the Merger Agreement. Subject to the terms and conditions of the Tender and Support Agreement, such stockholders agreed, among other things, to tender their Shares in the Offer no later than ten business days following the commencement of the Offer and, if required, to vote their Shares in favor of adoption of the Merger Agreement.

On August 31, 2010, prior to the execution of the Merger Agreement, the board of directors of the Company approved an Amendment (the “Amendment”) to the Shareholder Rights Agreement, dated as of November 14, 2008, between the Company and American Stock Transfer & Trust Company LLC, as rights agent (the “Rights Agreement”).

The Amendment, among other things, renders the Rights Agreement inapplicable to the Merger, the Offer, the Tender and Support Agreement, the Merger Agreement and the transactions contemplated thereby. The Amendment provides that the execution and delivery of the Merger Agreement and/or the Tender and Support Agreement, or the consummation of the Offer, the Merger and/or the other transactions contemplated by the Merger Agreement, will not be deemed to result in either Kenexa or Purchaser becoming an “Acquiring Person” (as such term is defined in the Rights Agreement). In addition, the Amendment provides that none of a “Stock Acquisition Date,” a “Distribution Date,” a “Section 11(a)(ii) Event” or a “Section 13 Event” (each as defined in the Rights Agreement) shall occur, and that “Rights” (as defined in the Rights Agreement) will not separate from the Shares, in each case, by reason of the execution and delivery of the Merger Agreement and/or the Tender and Support Agreement, or the consummation of the Offer, the Merger and/or the other transactions contemplated by the Merger Agreement. The Amendment also provides that the Rights Agreement shall expire on the Acceptance Date (as defined in the Merger Agreement) if the Rights Agreement has not otherwise terminated. If the Merger Agreement is terminated, the changes to the Rights Agreement pursuant to the Amendment will be of no further force and effect. The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment, which is filed as Exhibit 4.1 hereto and is incorporated herein by reference.

On September 1, 2010, the Company and Kenexa issued a joint press release relating to the Merger Agreement. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
