~~Item~~The ~~9.01.~~Company ~~Financial~~has ~~Statements~~made various representations and ~~Exhibits~~warranties and agreed to specified covenants in the Merger Agreement, including covenants relating to the conduct of the Company’s business between the date of the Merger Agreement and the closing of the Merger and other matters, including the “go-shop” and “no-shop” covenants described below.

During the period beginning on the date of the Merger Agreement and continuing until 11:59 p.m. Eastern Time on January 10, 2013 (dthe “Go-Shop Period”) ~~Exhibits~~, the Company may initiate, solicit and encourage any alternative acquisition proposals from third parties, provide nonpublic information to such third parties pursuant to acceptable confidentiality agreements and participate in discussions and negotiations with such third parties regarding alternative acquisition proposals. Starting at 12:00 a.m. on January 11, 2013, the Company will become subject to customary “no-shop” restrictions on its ability to initiate, solicit or encourage alternative acquisition proposals from third parties, provide nonpublic information to such third parties pursuant to acceptable confidentiality agreements and participate in discussions and negotiations with such third parties regarding alternative acquisition proposals, except that the Company may, for thirty days following the end of the Go-Shop Period, continue to engage in the aforementioned activities with third parties that made an alternative acquisition proposal during the Go-Shop Period that the Special Committee believes in good faith is, or could reasonably be expected to result in, a Superior Proposal (as defined in the Merger Agreement). In addition, after the Go-Shop Period, in response to any unsolicited alternative acquisition proposal received from any third party, the Company may provide nonpublic information to such party pursuant to an acceptable confidentiality agreement and participate in discussions and

~~Exhibit 99.2 Certain~~negotiations ~~supplemental~~with ~~information~~such ~~not~~party, ~~included~~if the Special Committee determines in good faith that failure to take such action would be inconsistent with the ~~press~~directors’ ~~release~~fiduciary duties under applicable law and any such alternative acquisition proposal is, or could reasonably be expected to result in, a Superior Proposal.

2Prior to the approval of the Merger by the Company’s stockholders, the no-shop provision is subject to a “fiduciary out” provision, which permits the Board, subject to compliance with certain obligations described below, to (i) change its recommendation to the Company’s stockholders regarding the Merger or terminate the Merger Agreement, in either case due to an intervening event, or (ii) approve a Superior Proposal and terminate the Merger Agreement to enter into such Superior Proposal, if, with respect to either (i) or (ii), the Special Committee determines in good faith (after consultation with its financial advisor and outside legal counsel) that the failure to do so would be inconsistent with its fiduciary duties under applicable law. Before exercising this “fiduciary out” however, the Board must provide Parent with three business days’ prior written notice of its intentions, the basis for its action and, if applicable, the material terms of any Superior Proposal. During such three business day period, the Company must, at Parent’s request, engage in certain discussions or negotiations with Parent. After three business days, and taking into account any changes to the Merger Agreement and the related transaction documents offered in writing by Parent, if Board determines in good faith (after consultation with its financial advisor and outside legal counsel) that, as applicable, (i) the failure to effect a change of recommendation or termination due to an intervening event would be inconsistent with its fiduciary duties under applicable law or (ii) the Superior Proposal continues to constitute a Superior Proposal, then the Board may exercise its “fiduciary out.” In the event of any amendment to the financial terms or any other material amendment of a Superior Proposal, the Company must deliver to Parent two business days’ prior written notice and again comply with the applicable requirements described above.

~~SIGNATURES~~The Merger Agreement contains certain termination rights for the Company and Parent. Upon termination of the Merger Agreement under specified circumstances, the Company will be required to pay Parent a termination fee. If the termination fee becomes payable under certain circumstances during the sixty-day period following the date of the Merger Agreement, the amount of the termination fee will be $8,019,250. In all other instances in which a fee is due to Parent, the amount of the termination fee will be $18,711,500. The Company will be required to reimburse third-party expenses incurred by Parent in connection with the Merger Agreement in an amount not to exceed $5,346,000 in the event that the Merger Agreement is terminated under certain circumstances. Parent will be required to reimburse third-party expenses incurred by the Company in connection with the Merger Agreement in an amount not to exceed $5,346,000 in the event that the Merger Agreement is terminated under certain circumstances. The Merger Agreement also provides that Parent will be required to pay the Company a reverse termination fee of $32,076,750 under certain circumstances specified in the Merger Agreement. Siris Partners II, L.P., an affiliate of Siris and Parent, has provided the Company with a limited guarantee in favor of the Company guaranteeing the payment of the reverse termination fee and certain other monetary obligations that may be owed by Parent pursuant to the Merger Agreement.

~~Pursuant~~The torepresentations, warranties and covenants of the ~~requirements~~Company contained in the Merger Agreement have been made solely for the benefit of Parent and Merger Sub. In addition, such representations, warranties and covenants (i) have been made only for purposes of the Merger Agreement, (ii) have been qualified by matters specifically disclosed in any reports filed by the Company with the Securities and Exchange ~~Act~~Commission (“SEC”) prior to the date of ~~1934~~the Merger Agreement and confidential disclosures made to Parent and Merger Sub in connection with the Merger Agreement, (iii) are subject to materiality qualifications contained in the ~~registrant~~Merger ~~has~~Agreement ~~duly~~that ~~caused~~may differ from what may be viewed as material by investors, (iv) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement, and (v) have been included in the Merger Agreement for the purpose of allocating risk between the contracting parties rather than establishing matters as fact. Accordingly, the Merger Agreement is included with this ~~report~~filing only to beprovide ~~signed~~investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the Company or its business. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company or any of its ~~behalf~~subsidiaries or affiliates.

The statements contained in this report that are not historical facts are forward-looking statements within the meaning of The Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on current expectations, forecasts and assumptions that are subject to risks and uncertainties that could cause actual results to differ materially from those set forth in, or implied by, the forward-looking statements.
