Section 2.8. Directors and Officers. Merger Sub’s directors and officers immediately prior to the Effective Time will be the Surviving Corporation’s initial directors and officers.

Section 2.9. Effect on Capital Stock. At the Effective Time, because of the Merger and without any action on the part of Parent, Merger Sub, or the Company:

(b) Common Stock of Merger Sub. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each share of Merger Sub’s common stock issued and outstanding immediately prior to the Effective Time will be converted into and exchanged for one validly issued, fully paid, and nonassessable share of the Surviving Corporation’s common stock.

All such shares of Company Common Stock, when so converted, will no longer be outstanding and will automatically be canceled and retired and will cease to exist, and the holder of a Company Stock Certificate that, immediately prior to the Effective Time, represented outstanding shares of Company Common Stock will cease to have any rights with respect thereto, except the right to receive, upon the surrender of such Company Stock Certificate, the Per Share Merger Consideration without interest except as provided in Section 2.12.

After the Effective Time, the Company’s stock transfer books will be closed and there will be no further transfers of shares of Company Common Stock following the Effective Time. If, at or after the Effective Time, Company Stock Certificates are presented to the Surviving Corporation, they will be canceled and exchanged in accordance with this Agreement.

Section 2.10. Surrender of Certificates.

Promptly after the Effective Time, the Surviving Corporation shall cause the Paying Agent to mail to each Person who was, at the Effective Time, a holder of record of shares of Company Common Stock entitled to receive the Per Share Merger Consideration payable on shares of Company Common Stock pursuant to Section 2.9 hereof (the “Stockholders”), a form of letter of transmittal in the form of Exhibit G attached hereto and instructions for use in effecting the surrender of shares of Company Common Stock pursuant to such letter of transmittal. Upon surrender to the Paying Agent of a Company Stock Certificate, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor the Per Share Merger Consideration payable on shares of Company Common Stock for each share of Company Common Stock formerly evidenced by such Company Stock Certificate and such Company Stock Certificate shall thereupon be cancelled. No interest shall accrue or be paid on the Per Share Merger Consideration payable upon the surrender of any Company Stock Certificate for the benefit of the holder of such Company Stock Certificate and any required withholding taxes on the Per Share Merger Consideration payable on shares of Company Common Stock may be withheld by Parent, the Surviving Corporation, or the Paying Agent. All interest accrued in respect of the cash deposited with the Paying Agent shall accrue to the benefit of and be paid to the Surviving Corporation.

(b) After surrender to the Paying Agent of any Company Stock Certificate or other instrument which prior to the Effective Time shall have represented any share of Company Common Stock, the Paying Agent shall, promptly distribute to the Person in whose name such Company Stock Certificate or other instrument shall have been registered, a check representing the Per Share Merger Consideration payable on shares of Company Common Stock that such Person has the right to receive pursuant to the provisions of this Section 2.10. Until so surrendered and cancelled, each such Company Stock Certificate or other instrument shall, after the Effective Time, be deemed to represent only the right to receive the Per Share Merger Consideration payable on shares of Company Common Stock, and until such surrender and cancellation, no cash shall be paid to the holder of such outstanding Company Stock Certificate or other instrument in respect thereof. From and after the Effective Time, the holders of shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease, except for Dissenting Shares and otherwise as required by law, to have any rights with respect to such shares of Company Common Stock, other than the right to receive the Per Share Merger Consideration payable on shares of Company Common Stock as provided in this Agreement.

(c) If payment is to be made to a Person other than the registered holder of the shares of Company Common Stock represented by the Company Stock Certificate or other instrument so surrendered in exchange therefor, it shall be a condition to such payment that the Company Stock Certificate or other instrument so surrendered shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such payment shall pay to the Paying Agent any transfer or other taxes required as a result of such payment to a Person other than the registered holder of such shares of Company Common Stock or establish to the satisfaction of the Paying Agent that such tax has been paid or is not payable.

(d) If any cash deposited with the Paying Agent for purposes of payment in exchange for the shares of Company Common Stock remains unclaimed six (6) months after the Effective Time, such cash shall be returned to the Surviving Corporation, upon demand, and any such holder who has not converted the shares of Company Common Stock into the Per Share Merger Consideration payable on shares of Company Common Stock pursuant to this Agreement prior to that time shall thereafter look only to the Surviving Corporation for payment of the Per Share Merger Consideration payable on shares of Company Common Stock. Notwithstanding the foregoing, the Surviving Corporation shall not be liable to any holder of shares of Company Common Stock for any amount paid to a public official pursuant to applicable unclaimed property laws. Any amounts remaining unclaimed by holders of shares of Company Common Stock or Converted Options seven (7) years after the Effective Time (or such earlier date immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity) shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of any claims or interest of any Person previously entitled thereto.

(e) Any portion of the Per Share Merger Consideration made available to the Paying Agent to pay for shares of Company Common Stock for which dissenters’ rights have been perfected as provided in Section 2.12 shall be returned to the Surviving Corporation upon demand.

(f) In the event that any Company Stock Certificate or other instrument representing shares of Company Common Stock shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate or other instrument to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such holder of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Company Stock Certificate or other instrument, the Paying Agent will issue in exchange for and in lieu of such lost, stolen or destroyed certificate or other instrument representing shares of Company Common Stock, the applicable Per Share Merger Consideration payable on shares of Company Common Stock, pursuant to this Agreement and the Merger, without interest and less any required withholding taxes.

(g) All Per Share Merger Consideration payable on shares of Company Common Stock will be deemed to have been issued in full satisfaction of all rights pertaining to shares of Company Common Stock.

Section 2.11. Stock Options and Warrants.

(a) Each Company Option that is not an In-the-Money Company Option shall be cancelled at the Effective Time, without any payment or other consideration therefore.

(b) All In-the-Money Company Options (the “Converted Options”), whether vested or not vested, shall be cancelled at the Effective Time, and, in lieu thereof, shall be converted into the right to receive, per share of Company Common Stock issuable upon exercise in full of such In-the-Money Company Option, a cash payment equal to the excess of the Per Share Merger Consideration for shares of Company Common Stock subject to the Converted Option, if such Converted Option were exercised in full, over the aggregate exercise price payable upon exercise in full of such Converted Option, as reduced by any required tax withholdings (collectively, the “Converted Option Merger Consideration”).

(c) Prior to the Effective Time, the Company shall take all steps necessary to make any amendments to the terms of such stock option plans, individual option agreements or Options that are necessary to give effect to the Transactions contemplated by this Agreement. At or prior to the Effective Time, the Company shall take all reasonable and necessary action to facilitate the timely exercise of rights and obligations to effectuate the provisions of this Section 2.11.

(d) At the Effective Time, the Surviving Corporation shall deliver to the Paying Agent a list of the names and addresses of the holders of the Converted Options (the “Converted Option Holders”) and, with respect to each Converted Option, deposit or cause to be deposited with the Paying Agent the aggregate amount of the Converted Option Merger Consideration payable on the Converted Options. Promptly after the Effective Time, the Surviving Corporation shall cause the Paying Agent to mail to each Converted Option Holder a letter of transmittal and instruction in the form of Exhibit G attached hereto, for use in obtaining payment of the Converted Option Merger Consideration to which such Converted Option Holder is entitled. Upon delivery to the Paying Agent such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, together with such option agreement, warrant or other instrument which prior to the Effective Time shall have represented any Company Option, and such other documents as may be required pursuant to such instructions, the Converted Option Holder shall be entitled to receive in exchange for the Converted Option held the Converted Option Merger Consideration to which such Converted Option Holder is entitled. No interest shall accrue or be paid on the Converted Option Merger Consideration payable with respect to any Converted Option and any required withholding taxes on the Converted Option Merger Consideration payable on the Converted Options may be withheld by Parent, the Surviving Corporation, or the Paying Agent. All interest accrued in respect of the cash deposited with the Paying Agent shall accrue to the benefit of and be paid to the Surviving Corporation.

(e) From and after the Effective Time, other than as expressly set forth in this Section 2.11 or any written agreement between the Company, the Parent and the holders of Company Options outstanding immediately prior to the Effective Time, no holder of Company Options shall have any rights with respect to such Company Options, other than to receive the

Converted Option Merger Consideration, if any payable thereon as provided herein. The surrender of any Company Option, the delivery of any letter of transmittal, or the receipt of cash in cancellation of such Company Option by the holder of such Company Option shall be deemed a release of any and all rights the holder of such Company Option had or may have had in respect of such Company Option except as expressly provided by this Agreement.

(f) All Converted Option Merger Consideration payable on Converted Options will be deemed to have been issued in full satisfaction of all rights pertaining to the Converted Options.

Section 2.12. Shares of Dissenting Stockholders. Notwithstanding Section 2.9(c) hereof, to the extent that holders of shares of Company Common Stock are entitled to appraisal rights under Section 262 of the DGCL, shares of Company Common Stock issued and outstanding immediately prior to the Effective Time and held by a holder who has properly exercised and perfected his or her demand for appraisal rights under the DGCL (the “Dissenting Shares”), shall not be converted into the right to receive the Per Share Merger Consideration, but the holders of such Dissenting Shares shall be entitled to receive such consideration as shall be determined pursuant to DGCL (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall cease to have any rights with respect thereto, except the right to receive such consideration as shall be determined pursuant to the DGCL); provided, however, that if any such holder shall have failed to perfect or shall have effectively withdrawn or lost his or her right to appraisal and payment under the DGCL, such holder’s shares of Company Common Stock shall thereupon be deemed to have been converted as of the Effective Time into the right to receive the Per Share Merger Consideration without any interest thereon and such shares shall not be deemed to be Dissenting Shares. Any payments required to be made with respect to the Dissenting Shares shall be made by the Surviving Corporation (and not the Company, Merger Sub Parent) and the Aggregate Transaction Consideration shall be reduced, on a dollar for dollar basis, as if the holder of such Dissenting Shares had not been a stockholder on the Merger Closing Date. The Company will give Parent (a) prompt notice of any written demands for the exercise of dissenters or appraisal rights, withdrawals of demands for the exercise of dissenters or appraisal rights and any other instruments served under the DGCL, and (b) the opportunity to direct all negotiations and proceedings with respect to demands for exercise of dissenters or appraisal rights under the DGCL. The Company will not voluntarily make any payment with respect to any purchase demands and will not, except with Parent’s prior written consent, settle or offer to settle any such demands.

Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form shall be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The Parties intend that each representation, warranty, and covenant contained herein will have independent significance. If any Party has Breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which the Party has not Breached will not detract from or mitigate the fact that the Party is in Breach of the first representation, warranty, or covenant.

Section 8.14. Remedies. Except as expressly provided herein, the rights, obligations and remedies created by this Agreement are cumulative and in addition to any other rights, obligations, or remedies otherwise available at Law or in equity. Except as expressly provided herein, nothing herein will be considered an election of remedies.

Section 8.15. Electronic Signatures.

(a) Notwithstanding the Electronic Signatures in Global and National Commerce Act (15 U.S.C. Sec. 7001 et. seq.), the Uniform Electronic Transactions Act, or any other Law relating to or enabling the creation, execution, delivery, or recordation of any contract or signature by electronic means, and notwithstanding any course of conduct engaged in by the Parties, no Party will be deemed to have executed a Transaction Document or other document contemplated thereby (including any amendment or other change thereto) unless and until such Party shall have executed such Transaction Document or other document on paper by a handwritten original signature or any other symbol executed or adopted by a Party with current intention to authenticate such Transaction Document or such other document contemplated.

(b) Delivery of a copy of a Transaction Document or such other document bearing an original signature by facsimile transmission (whether directly from one facsimile device to another by means of a dial-up connection or whether mediated by the worldwide web), by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature. “Originally signed” or “original signature” means or refers to a signature that has not been mechanically or electronically reproduced.
