3. The board of directors of SoundBite (the “SoundBite Board”) has unanimously (i) determined that the terms and provisions of the Agreement and Plan of Merger, dated as of May 20, 2013, by and among Genesys, Offeror and SoundBite (as it may be amended from time to time, the “Merger Agreement”) and the transactions contemplated by the Merger Agreement, including the Merger (as defined below) and the Offer, are advisable, fair to and in the best interests of the Company and the holders of Shares, (ii) found that the Offer Price of $5.00 to be paid to the holders of Shares in the Offer that Genesys is to cause Offeror to commence pursuant to the

Merger Agreement is fair to, and in the best interests of the holders of Shares, (iii) found that the Merger Consideration to be paid to the holders of Shares in the Merger to be effected following consummation of the Offer is fair to, and in the best interests of the holders of Shares, (iv) approved, adopted, and confirmed in all respects the Merger Agreement and authorized and directed that SoundBite enter into the Merger Agreement, (v) approved and declared advisable the Merger Agreement, the tender and support agreements between Genesys, Offeror and certain supporting stockholders of SoundBite (the “Support Agreements”), the Offer and the Merger on the terms and subject to the conditions set forth therein, and (vi) recommended that you accept the Offer, tender your Shares to the Offeror pursuant to the Offer and, if required by applicable law, vote to adopt the Merger Agreement.

4. The Offer is being made pursuant to the Merger Agreement under which, following the completion of the Offer and the satisfaction or waiver of certain terms and conditions, the Offeror will be merged with and into SoundBite (the “Merger”), with SoundBite continuing as the surviving corporation and becoming a direct wholly-owned subsidiary of Genesys (the “Surviving Corporation”). At the effective time of the Merger (the “Merger Effective Time”), each Share issued and outstanding immediately prior to the Merger Effective Time (excluding Shares owned, directly or indirectly, by (i) SoundBite (including treasury shares), Genesys or any of its subsidiaries (including Offeror), which will be canceled automatically and retired and will cease to exist, and no cash or other consideration will be delivered with respect thereto, or (ii) stockholders of SoundBite who properly exercised their appraisal rights in compliance with Section 262 of the DGCL) will be converted into a right to receive an amount in cash equal to the Offer Price (the “Merger Consideration”), payable without interest and less any applicable withholding taxes. The Merger Agreement provides that, immediately prior to the Merger Effective Time, each outstanding option to acquire Shares (an “Option”) granted under SoundBite’s 2000 Stock Option Plan and/or SoundBite’s 2007 Stock Incentive Plan, or otherwise (collectively, the “Stock Plans”), whether or not vested and exercisable, will be automatically converted into the right to receive, immediately after the Merger Effective Time, an amount in cash equal to the excess, if any, of the Merger Consideration over the per share exercise price of such Option multiplied by the aggregate number of Shares that were issuable upon exercise or settlement of such Option immediately prior to the Merger Effective Time. The Merger Agreement provides that upon the earlier of (i) such time as Offeror’s designees first constitute at least a majority of the SoundBite Board and (ii) the Merger Effective Time (in either case, the “Control Time”), each restricted stock unit award outstanding under the Stock Plans (an “RSU”) immediately prior to the Control Time will become fully vested and, as of the Control Time, will be cancelled and extinguished and exchanged for the right to receive, immediately after the Control Time, an amount in cash equal to the total number of Shares subject to such RSU immediately prior to the Control Time multiplied by the Merger Consideration. Any payments required to be made under the Merger Agreement in respect of each Option and each RSU shall be made by the Genesys or Surviving Corporation without interest and less taxes required to be withheld through SoundBite’s payroll systems. The Merger Agreement is more fully described in Section 13 of the Offer to Purchase.
