(v) against any proposal, action, agreement, or transaction that would reasonably be expected to result in any of the conditions to the consummation of the Merger set forth in Article VII of the Merger Agreement not being fulfilled or satisfied; and

(vi) against any other proposal, action, agreement, or transaction that would reasonably be expected to impede, interfere with, delay, postpone, discourage, or adversely affect the timely consummation of the Merger or any of the other transactions contemplated by the Merger Agreement or this Agreement, or that would reasonably be expected to diminish in any material respect the benefits expected to be derived by Parent as a result of the transactions contemplated by the Merger Agreement.

(b) Stockholder hereby agrees that it shall, and shall cause the holder of record of any Subject Shares to, be present (in person or by proxy) at all meetings of the stockholders of the Company at which any of the matters described in this Section 1.1 are to be considered so that all Subject Shares beneficially owned by Stockholder may be counted for purposes of determining the presence of a quorum at such meetings. In the event that a meeting of stockholders is adjourned or postponed, Stockholder shall, and shall cause the holder of record of any Subject Shares to, attend such adjourned or postponed meeting.

(c) Any vote required to be cast or consent required to be delivered pursuant to this Section 1.1 shall be cast or delivered by Stockholder (or caused to be cast or delivered by Stockholder) promptly (and in any event no later than five (5) Business Days prior to the applicable record date) in accordance with such procedures relating thereto as shall ensure that it is duly counted, including by execution of a written consent, if applicable, or by timely delivery to the Company of a properly completed proxy card with respect to such vote.

(b) Stockholder hereby affirms that the Proxy granted pursuant to this Section 1.2 is:

(iii) granted in consideration of Parent's and Merger Sub's entering into the Merger Agreement, which consideration Stockholder acknowledges is adequate and sufficient.

(c) The Proxy granted pursuant to this Section 1.2 shall automatically terminate upon the termination of this Agreement in accordance with Article V.

Section 6.7 WAIVER OF JURY TRIAL.

EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING, CLAIM, OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE, AND ENFORCEMENT OF THIS AGREEMENT. EACH PARTY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT, OR ATTORNEY OF THE OTHER PARTIES HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6.7.

Section 6.8 Specific Performance.

The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, each Party shall be entitled to an injunction or injunctions, specific performance, and other equitable relief to prevent breaches of this Agreement and to enforce specifically the performance of the terms and provisions of this Agreement, in each case without the necessity of proving actual damages, posting any bond, or furnishing any other security, this being in addition to any other remedy to which any Party is entitled at law or in equity. Each Party further agrees that it will not oppose the granting of an injunction, specific performance, or other equitable relief on the basis that (a) any other Party has an adequate remedy at law or (b) an award of specific performance is not an appropriate remedy for any reason at law or in equity. The Parties acknowledge and agree that any Party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 6.8 shall not be required to provide any bond or other security in connection with any such order or injunction.

Section 6.9 Severability.

If any term or other provision of this Agreement is held to be invalid, illegal, or unenforceable under any applicable law or public policy, all other terms and provisions of this Agreement shall nevertheless continue in full force and effect for so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any Party. Upon a determination that any term or other provision of this Agreement is invalid, illegal, or unenforceable, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement may be consummated as originally contemplated to the greatest extent possible.

Section 6.10 Counterparts.

This Agreement may be executed in one or more counterparts, each of which when executed shall be deemed to be an original, and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic transmission (including portable document format (.pdf), Brightwater Software, or any other electronic signature complying with the U.S. federal ESIGN Act of 2000) shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 6.11 No Third-Party Beneficiaries.

This Agreement shall be binding upon and inure solely to the benefit of each Party and its respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any Person other than the Parties (and their respective heirs, executors, administrators, successors, and permitted assigns) any right, benefit, or remedy of any nature whatsoever under or by reason of this Agreement.

Section 6.12 Interpretation.

(a) The headings and captions contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

(b) Whenever the words "include," "includes," or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation."

(g) The Parties have participated jointly in the negotiation and drafting of this Agreement, and in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provision of this Agreement.

(h) References to any statute, rule, or regulation are to that statute, rule, or regulation as amended, modified, supplemented, or replaced from time to time (and, in the case of a statute, include any rules and regulations promulgated under such statute), and references to any section of a statute, rule, or regulation include any successor to such section.
