In the event that Parent and the Escrow Participant Representative cannot agree on such a national firm of independent certified public accountant, the names of the national accounting firms, exclusive of any such firm which is rendering or has in the past three (3) years rendered services to Parent or the Escrow Participant Representative or their respective Affiliates, shall be selected by lottery until one such firm is willing to compute the disputed payments for purposes of this Agreement. The expenses of any such firm selected by Parent and the Escrow Participant Representative to resolve computational disputes hereunder shall be borne equally by Parent and the Stockholders (for payments by the Stockholders, such amounts shall be deducted from the Additional Stockholder Consideration; for payments by the Eligible Employees, such amounts shall be deducted from the Additional Eligible Employee Consideration). In the event the amount of any Additional Consideration to be paid by Parent to the Stockholders or Eligible Employee in accordance with Sections 2.8.5 or 2.8.6 is recomputed in accordance with this subsection, any increase or decrease to the amount of Additional Consideration shall be carried forward to be added to or deducted from the Quarterly Earn-Out Pool for the next fiscal quarter (or, with respect to the final quarter of the Earn-Out Tail Period, at the expiration of the Earn-Out Tail Period).

Section 2.9 No Further Ownership Rights in Shares of Company Stock. The Transaction Consideration delivered upon the surrender for exchange of Company Stock in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Stock, and there shall be no further registration of transfers of Company Stock which were outstanding immediately prior to the Effective Time on the records of the Surviving Corporation. If, after the Effective Time, the Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article 2.

Section 2.10 Lost, Stolen or Destroyed Certificates. In the event any Certificates shall have been lost, stolen or destroyed, Parent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, such Transaction Consideration as may be required pursuant to Section 2.6 and 2.8.5 of this Agreement; provided, however, that Parent may, in its sole discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to deliver an indemnity or bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent with respect to the Certificates alleged to have been lost, stolen or destroyed.

Section 2.11 Dissenting Shares. Any holder of shares of Company Stock issued and outstanding immediately prior to the Effective Time with respect to which dissenters’ rights, if any, are available by reason of the Merger pursuant to Section 262 of the DGCL or Chapter 13 of the California General Corporation Law (the “CGCL”) who has not voted in favor of the Merger or consented thereto in writing and who complies with Section 262 of the DGCL or Chapter 13 of the CGCL (“Company Dissenting Shares”) shall not be entitled to receive any portion of the Transaction Consideration pursuant to this Article 2, unless such holder fails to perfect, effectively withdraws or loses its dissenters’ rights under the DGCL or the CGCL. Such holder shall be entitled to receive only such rights as are granted under Section 262 of the DGCL or Chapter 13 of the CGCL. If any such holder fails to perfect, effectively withdraws or loses such dissenters’ rights under the DGCL or the CGCL, such Company Dissenting Shares shall thereupon be deemed to have been converted as of the Effective Time into the right to receive the Transaction Consideration to which such shares of Company Stock are entitled pursuant to this Article 2, without interest. Prior to the Effective Time, the Company shall give Parent prompt notice of any demands for appraisal pursuant to Section 262 of the DGCL or Chapter 13 of the CGCL received by the Company, withdrawals of any such demands and any other documents or instruments received by the Company in connection therewith. Parent shall have the right to participate in and direct all negotiations and proceedings with respect to any such demands. Prior to the Effective Time, the Company shall not, except with the prior written consent of Parent and the Escrow Participant Representative, which consent shall not unreasonably be withheld or delayed, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing. Any payments made with respect to Company Dissenting Shares shall be made solely by the Surviving Corporation, and no funds or other property have been or shall be provided by Parent, Merger Sub or any of Parent’s Affiliates for such payment.

Section 2.12 Withholding. Parent shall be entitled to deduct and withhold from any consideration otherwise payable pursuant to this Agreement such amounts as it may be required to deduct and withhold with respect to the making of such payment under the Code, or any provision of applicable Tax Law. To the extent that amounts are so withheld or paid over to or deposited with the relevant Governmental Authority by Parent, such amounts shall be treated for all purposes of this Agreement as having been paid to the applicable Person in respect of which Parent made such deduction and withholding.

Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Parent, the Surviving Corporation and the Escrow Participant Representative agree (A) to retain all books and records with respect to Tax matters pertinent to each of the Company and the Subsidiaries of the Company relating to any Taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Parent, any extensions thereof) of the respective Taxable periods, and to abide by all record retention agreements entered into with any Taxing authority, (B) to deliver or make available to Parent, within sixty (60) days after the Closing Date, copies of all such books and records, and (C) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, Parent, the Surviving Corporation and the Escrow Participant Representative, as the case may be, shall allow the other party to take possession of such books and records at such other party’s expense. Parent and the Escrow Participant Representative further agree, upon request, to use their best efforts to obtain any certificate or other document from any governmental authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

Section 7.4.1 The parties intend the Merger and the Second Step Merger to qualify together as a reorganization under Section 368(a) of the Code. However, neither Parent nor the Company makes any representation or warranty to the other or to any Stockholder regarding the Tax treatment of the Merger or the Second Step Merger or whether the Merger and the Second Step Merger will qualify together as a reorganization under Section 368(a) of the Code. Each of the Company, the Stockholders and Parent acknowledges that it is relying on its own advisors in connection with the Tax treatment of the Merger, the Second Step Merger and the other transactions contemplated by this Agreement. The Company, the Stockholders and Parent each agree to use their respective commercially reasonable efforts to cause the Merger and the Second Step Merger to qualify together, and will not take any actions which to their Knowledge could reasonably be expected to prevent the Merger and the Second Step Merger from together qualifying, as a reorganization under Section 368(a) of the Code.

Section 7.4.2 This Agreement has been adopted as a “plan of reorganization” within the meaning Treasury Regulation Sections 1.368-2(g) and 1.368-3(a). Each of Parent and the Company shall report the Merger and the Second Step Merger as a reorganization within the meaning of Section 368(a) of the Code, unless otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code.

Section 7.5 Certain Taxes. All transfer, documentary, sales, use, stamp, registration and other substantially similar Taxes and fees (including any penalties and interest) incurred in

connection with this Agreement (collectively, “Transfer Taxes”), if any, shall be paid by the Stockholders when due, and the Stockholders shall, at their own expense, file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes and, if required by Applicable Law, Parent shall, and shall cause its Affiliates to, join in the execution of any such Tax Returns and other documentation.

Section 7.6 FIRPTA Certificate. On or prior to the Closing Date, the Company shall have delivered to Parent a form of notice to the Internal Revenue Service in accordance with the requirements of Treasury Regulation Section 1.897-2(h)(2) and in form and substance reasonably acceptable to Parent along with written authorization for Parent to deliver such notice form to the Internal Revenue Service on behalf of the Company upon the Closing of the Merger.

Section 7.7 Characterization of Payments. Any payments made to any Parent Indemnitees pursuant to Section 10.2 of this Agreement shall constitute an adjustment of the consideration paid for the Common Stock and Preferred Stock, as applicable, for Tax purposes and shall be treated as such by the parties on their Tax Returns to the extent permitted by Law.

Section 7.8 Carrybacks. The parties agree and acknowledge that any net operating losses or similar Tax attribute of the Company and its Subsidiaries is an asset of the Company and its Subsidiaries that (subject to any applicable limitations imposed by Law) is being acquired by Parent pursuant to the Merger, and that the Company and its Subsidiaries shall, to the extent permitted by Applicable Law, elect not to carryback any such Tax attributes to Tax periods of the Company and its Subsidiaries prior to the Closing Date or otherwise act so as to limit the ability of Parent to use such attributes subsequent to the Merger.

Merger has not been consummated by September 3, 2004 (the “Outside Date”); provided, however, that no party may terminate this Agreement pursuant to this clause (ii) if such party’s failure to fulfill any of its obligations under this Agreement shall have been the reason that the Effective Time shall not have occurred on or before said date;

Section 9.1.3 by Parent and Merger Sub if there shall have been (i) a breach by the Company of any of its representations or warranties contained in this Agreement, or if any such representation or warranty shall have become untrue, or (ii) a breach or nonperformance by the Company of any of its covenants or agreements contained in this Agreement, such that, in the case of either (i) or (ii) above, the conditions set forth in Section 8.3.1 and 8.3.2 would not be satisfied; provided, however, that if such breach, inaccuracy or nonperformance is curable by the Company through the exercise of its commercially reasonable efforts within fifteen (15) Business Days after notice to Parent (the “Company Cure Period”), then Parent and Merger Sub may not terminate this Agreement pursuant to this Section 9.1.3 prior to the expiration of the Company Cure Period (it being understood and agreed that the Company shall promptly notify Parent of any such breach, inaccuracy or nonperformance of which the Company has Knowledge and shall continue to exercise commercially reasonable efforts to cure such breach, inaccuracy or nonperformance during the Company Cure Period) and provided further that Parent and Merger Sub may not terminate the Agreement pursuant to this Section 9.1.3 if Parent and Merger Sub are in material breach of their obligations under this Agreement, including, but not limited to that the conditions in Section 8.2.1 and 8.2.2 could not be satisfied by Parent and Merger Sub at such time;

Section 9.1.4 by Parent and Merger Sub if the approval by the stockholders of the Company required for the consummation of the Merger or the other transactions contemplated hereby or by the Ancillary Agreements shall not have been obtained by reason of the failure to obtain the required vote at a duly held meeting of the stockholders of the Company or at any adjournment thereof due to the existence of an Acquisition Proposal (other than the Merger);

Section 9.1.5 by the Company if there shall have been (i) a breach by Parent or Merger Sub of any of their representations or warranties contained in this Agreement, or if any such representation or warranty shall have become untrue, or (ii) a breach or nonperformance by Parent or Merger Sub of any of their covenants or agreements contained in this Agreement, such that, in the case of either (i) or (ii) above, the conditions set forth in Section 8.2.1 and 8.2.2 would not be satisfied; provided, however, that if such breach, inaccuracy or nonperformance is curable by Parent or Merger Sub through the exercise of its commercially reasonable efforts within fifteen (15) Business Days after notice to the Company (the “Parent Cure Period”), then the Company may not terminate this Agreement pursuant to this Section 9.1.5 prior to the expiration of the Parent Cure Period (it being understood and agreed that Parent shall promptly notify the Company of any such breach, inaccuracy or nonperformance of which Parent has Knowledge and shall continue to exercise commercially reasonable efforts to cure such breach, inaccuracy or nonperformance during the Parent Cure Period) and provided further that Company may not terminate the Agreement pursuant to this Section 9.1.5 if Company is in material breach of its obligations under this Agreement, including, but not limited to that the conditions in Section 8.3.1 and 8.3.2 could not be satisfied by Company at such time;

Section 10.2.1 Indemnification by the Escrow Participants. From and after the Closing Date, each of the Escrow Participants shall, severally in proportion to their respective Pro Rata Shares and not jointly, indemnify and hold Parent, Merger Sub, the Company and each of their Subsidiaries, and each of their respective officers, directors, employees, members, stockholders, agents and representatives (“Parent Indemnitees”) harmless from and against all losses, damages, liabilities, claims, demands, obligations, deficiencies, payments, judgments, settlements, costs, Tax Costs and expenses of any nature whatsoever (including the costs and expenses of any and all investigations, actions, suits, proceedings, demands, assessments, judgments, orders, settlements and compromises relating thereto, and reasonable attorneys’, accountants’, experts’ and other fees and expenses in connection therewith) (“Losses”) resulting from, arising out of, or due to, directly or indirectly, any of the following:

Section 10.2.1.1 Any inaccuracy or misrepresentation in, or breach or nonfulfillment of, any representation or warranty of the Company, or any breach or nonfulfillment of any covenant of the Company, contained in this Agreement, in any schedule delivered hereunder by the Company, or in any certificates delivered by the Company pursuant to this Agreement;

Section 10.2.1.3 With respect to each Company Dissenting Share, any payments made by Parent in respect of any demands for appraisal of such Company Dissenting Share to the extent such payments exceed the net amount ultimately paid (taking into account the effect of indemnification payments pursuant to this Article 10 and the Escrow Agreement) with respect to a share of Company Stock of the same class and series that is not a Company Dissenting Share pursuant to this Agreement, each Parent Common Share being valued for such purpose at the Closing Measurement Price, plus the reasonable fees and expenses of Parent incurred in connection with the defense of such demands; and

Section 10.2.1.4 (i) Any Taxes of any of the Company and the Subsidiaries of the Company with respect to any Tax year or portion thereof ending on or before the Closing Date (or for any Tax year beginning before and ending after the Closing Date, to the extent allocable (as determined in the following sentence) to the portion of such period beginning before and ending on the Closing Date), except to the extent that such Taxes are reflected in the reserve for Tax liability (rather than any reserve for deferred Taxes established to reflect timing differences between book and Tax income) shown on the face of the balance sheets (rather than in any notes thereto) contained in the Interim Period Unaudited Company Financial Statements, as such reserve is adjusted for the passage of time through the Closing Date in accordance with past custom and practice of the Company and its Subsidiaries in filing their Tax Returns, and (ii) the unpaid Taxes of any Person that are imposed on the Company or the Surviving Corporation or Merger Sub 2 (other than any of the Company and its Subsidiaries) under Treasury Regulations Section 1.1502-6 (or any similar provision of state, local or foreign law), as a transferee or successor, by contract, or otherwise. For purposes of the preceding sentence, in the case of any Taxes that are imposed on a periodic basis and are payable for a Tax period that includes (but does not end on) the Closing Date, the portion of such Tax that relates to the

portion of such Tax period ending on the Closing Date shall (i) in the case of any Taxes other than Taxes based upon or related to income or receipts, be deemed to be the amount of such Tax for the entire Tax period multiplied by a fraction the numerator of which is the number of days in the Tax period ending on the Closing Date and the denominator of which is the number of days in the entire Tax period, and (ii) in the case of any Tax based upon or related to income or receipts, be deemed equal to the amount which would by payable if the relevant Tax period ended on the Closing Date.

Section 10.2.1.5 Any of the matters set forth on Section 10.2.1.5 of the Company Disclosure Schedule.

Section 10.2.2.1 In the event that a Parent Indemnitee wishes to make any indemnification claim under this Section 10.2, such Parent Indemnitee shall provide written notice of such claim (an “Indemnification Notice”) to the Escrow Agent and the Escrow Participant Representative. Any such notice shall, to the extent practicable, set forth in reasonable detail the basis for the claim and shall include a good faith determination of the estimated amount of the claim. Thereafter, the Escrow Participant Representative shall have twenty (20) Business Days following the Escrow Participant Representative’s receipt of the Indemnification Notice in which to deliver notice of objection to such claim to the Parent Indemnitee and the Escrow Agent. If no objection notice is given, then the claim in the amount alleged by the Parent Indemnitee in the Indemnification Notice shall be deemed to be valid and indemnifiable pursuant hereto, and the Parent Indemnitee shall be entitled to offset the full amount of such claim against the Escrow Shares. No offset shall be permitted if the relevant claim is timely disputed as set forth above, unless and until its validity is finally resolved. In the event that the Parent Indemnitee is entitled to offset as a result of the final resolution of the validity of such claim, such Parent Indemnitee shall provide written notice (the “Resolved Claim Notice”) of such offset to the Escrow Agent and the Escrow Participant Representative. Within five (5) Business Days after receipt of the Resolved Claim Notice, the Escrow Agent shall deliver to such Parent Indemnitee a number of Escrow Shares equal in value to the amount of such offset. Each Escrow Participant shall be severally, and not jointly, liable for the dollar amount equal to the product of (x) the dollar amount set forth in such Resolved Claim Notice multiplied by (y) such Escrow Participant’s Pro Rata Share, but in no event greater than the value of the remaining Escrow Shares attributable to such Escrow Participant.

Section 10.3.1 Third-Party Claims. In order for a Person (the “Indemnified Party”) to be entitled to any indemnification provided for under Section 10.2 hereof in respect of, arising out of or involving a claim made by any Person against the Indemnified Party (a “Third-Party Claim”), such Indemnified Party must notify the indemnifying party in writing of the Third-Party Claim promptly following receipt by such Indemnified Party of written notice of the Third-Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except and only to the extent the indemnifying party demonstrates that it has been actually prejudiced as a result of such failure. Thereafter, the Indemnified Party shall deliver to the indemnifying party, as promptly as practicable following

the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third-Party Claim that are not separately addressed to the indemnifying party.

Section 10.3.2 Assumption. If a Third-Party Claim is made against an Indemnified Party, the indemnifying party shall be entitled to participate in the defense thereof and, if it so chooses, to assume the defense thereof with counsel selected by the indemnifying party; provided, however, that such counsel is not reasonably objected to by the Indemnified Party. Should the indemnifying party so elect to assume the defense of a Third-Party Claim, the indemnifying party shall not be liable to the Indemnified Party for any reasonable legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof. If the indemnifying party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the indemnifying party, it being understood that the indemnifying party shall control such defense; provided, however, that the indemnifying party shall bear the reasonable fees and expenses of such separate counsel (i) if the parties to any such action or proceeding (including impleaded parties) include any of the Stockholders and representation of both parties would, in the reasonable opinion of counsel for the Indemnified Party, be inappropriate due to a conflict of interest or (ii) if the indemnifying party shall not have employed counsel (other than counsel that is reasonably objected to by the Indemnified Party) within a reasonable time after the Indemnified Party has given notice of the institution of a Third-Party Claim in compliance with Section 10.3.1 hereof; provided, however, that in no event shall the indemnifying party have to bear the fees and expenses of more than one separate counsel for all Indemnified Parties. The indemnifying party shall be liable for the reasonable fees and expenses of counsel employed by the Indemnified Party for any period during which the indemnifying party has not assumed the defense thereof. If the indemnifying party chooses to defend or prosecute a Third-Party Claim, all the Indemnified Parties shall cooperate in the defense or prosecution thereof. Such cooperation shall include, to the extent within the control of each such Indemnified Party, the retention and (upon the indemnifying party’s request) the provision to the indemnifying party of records and information that are reasonably relevant to such Third-Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, such Third-Party Claim without the indemnifying party’s prior written consent (which consent shall not be unreasonably withheld or delayed). If the indemnifying party assumes the defense of a Third-Party Claim, the Indemnified Party shall agree to any settlement, compromise or discharge of a Third-Party Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Third-Party Claim (and, with respect to indemnification by the Escrow Participants, for which the Escrow Shares then remaining in the Escrow Account are sufficient to satisfy the entire settlement, compromise or discharge), which releases the Indemnified Party completely in connection with such Third-Party Claim and that would not otherwise adversely affect the Indemnified Party.

Section 10.4 Termination of Indemnification Obligations. The obligations to indemnify and hold harmless any Person pursuant to Sections 10.2 hereof shall terminate on the Expiration Date; provided, however, that such obligations to indemnify and hold harmless shall not

terminate with respect to any item as to which the Person to be indemnified shall have, before the expiration of the applicable period, previously made a bona fide claim by delivering a notice of such claim pursuant to Sections 10.2.2 or 10.3 hereof to the indemnifying party.

Section 10.5.1 Notwithstanding the foregoing, the Escrow Participants shall not be obligated to indemnify any Parent Indemnitee pursuant to Section 10.2.1.1 of this Agreement unless and until the aggregate of all Losses suffered by all Parent Indemnitees under this Agreement exceeds $250,000 (the “Threshold Amount”), whereupon, provided that the other requirements of this Article 10 have been complied with, the amount of all such Losses, and all subsequent Losses, shall become due and payable, up to the limits set forth in Section 10.5.2.

Section 10.5.2 Except in the case of fraud or criminal activity, the aggregate liability of each Escrow Participant for money damages under this Agreement shall be limited to the product of (x) the value of the Escrow Shares multiplied by (y) such Escrow Participant’s Pro Rata Share, and the Escrow Account and the indemnification provisions of this Article 10 shall be Parent’s sole remedy in connection with this Agreement and the transactions contemplated hereby.

Section 11.1 Entire Agreement. This Agreement (including the Company Disclosure Schedule, any other exhibits, schedules, certificates, lists and documents referred to herein, and any documents executed by the parties simultaneously herewith or pursuant thereto), the Ancillary Agreements and the Non-Disclosure Agreement constitute the entire agreement of the parties hereto, except as provided herein, and supersedes all prior agreements and understandings, written and oral, among the parties with respect to the subject matter hereof.

Section 11.2 Interpretation. When a reference is made in this Agreement to Sections, Exhibits or Schedules, such reference shall be to a Section of or an Exhibit or a Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The phrases “the date of this Agreement,” “the date hereof” and terms of similar import, unless the context otherwise requires, shall be deemed to refer to the date set forth in the first paragraph of this Agreement.

Section 11.3 Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broadly as is enforceable.

Section 11.4 Notices. Unless otherwise provided herein, all notices and other communications hereunder shall be in writing and shall be deemed given if (a) delivered in person, (b) transmitted by telecopy (with written confirmation), (c) mailed by certified or registered mail (return receipt requested) (in which case such notice shall be deemed given on the third (3^rd) day after such mailing, but only if deposited at a U.S. Postal Service office in California or Oregon) or (d) delivered by an express courier (with written confirmation) (in which case such notice shall be deemed given on the next Business Day) to the parties at the following addresses (or at such other address for a party as shall be specified by like notice):

Section 11.5 Binding Effect; Persons Benefiting; No Assignment. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and permitted assigns. Except for Section 2.8.6 and Section 6.13 (which are intended to be for the benefit of the Persons covered thereby and may be enforced by such Persons), no provision of this Agreement is intended or shall be construed to confer upon any entity or Person other than the parties hereto and their respective successors and permitted assigns any right, remedy or claim under or by reason of this Agreement or any part hereof. This Agreement may not be assigned by any of the parties hereto; provided, however, that Parent may assign all or part of its rights under this Agreement and delegate all or part of its obligations under this Agreement to (i) a wholly-owned Subsidiary of Parent, in which event all of the rights and powers of Parent and remedies available to Parent under this Agreement shall extend to and be enforceable by such Subsidiary (provided that Parent remains jointly and severally liable with such assignee for any obligations of Parent hereunder after such assignment) or (ii) any Person who acquires Parent, whether by way of merger or the purchase of all of Parent’s outstanding capital stock or substantially all of Parent’s assets. In the event of any such assignment and delegation, the term “Parent” as used in this Agreement shall be deemed to refer to such Subsidiary or successor of Parent, as the case may be, where reference is made with respect to actions to be taken with respect to the transactions contemplated by this Agreement and the Ancillary Agreements, and shall be deemed to include both Parent and such Subsidiary or successor of Parent, as the case may be, where appropriate.

Section 11.6 Counterparts; Facsimile Signatures. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same agreement, it being understood that all of the parties need not sign the same counterpart. This Agreement may be executed and delivered by facsimile and upon such delivery the facsimile signature shall be deemed to have the same effect as if the original signature had been delivered to the other party. The original signature copy shall be delivered to the other party by express overnight delivery in accordance with Section 11.4 hereof. The failure to deliver the original signature copy and/or the nonreceipt of the original signature copy shall have no effect upon the binding and enforceable nature of this Agreement.

Section 11.7 Waiver of Jury Trial. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 11.8 Governing Law. THIS AGREEMENT, THE LEGAL RELATIONS BETWEEN THE PARTIES AND THE ADJUDICATION AND THE ENFORCEMENT THEREOF, SHALL BE GOVERNED BY AND INTERPRETED AND CONSTRUED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO APPLICABLE CHOICE OF LAW PROVISIONS THEREOF.

Section 11.9 Consent to Jurisdiction. Except as otherwise expressly provided in any of the Ancillary Agreements, each of the parties hereto hereby irrevocably and unconditionally submits to the jurisdiction of any state court of the State of Delaware and any federal court sitting in Delaware and irrevocably agrees that all actions or proceedings arising out of or relating to this agreement or the transactions contemplated hereby or in aid or arbitration or for enforcement of an arbitral award shall be litigated exclusively in such courts. Each of the parties hereto agrees not to commence any legal proceedings related hereto except in such courts. Each of the parties hereto irrevocably waives any objection which he or it may now or hereafter have to the laying of the venue of any such proceeding in any such court and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed as of the date first above written.

WHEREAS, Parent, Merger Sub and the Company entered into the Agreement for purposes of effecting the merger of Merger Sub into the Company (the “Merger”), with the surviving corporation becoming a wholly-owned subsidiary of Parent;

WHEREAS, pursuant to the Agreement, after the Merger, the parties originally contemplated effecting a second-step merger (the “Second-Step Merger”), whereby the surviving corporation from the Merger would then be merged with and into Null Set Merger Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent;

WHEREAS, the parties now desire for the Second-Step Merger to be effected by merging the surviving corporation into a Delaware limited liability company instead of a Delaware corporation; and

WHEREAS, the parties to the Agreement also wish to make changes to certain definitions in the Agreement;

A. Section 1.1 of the Agreement is amended by restating the definition of “Stock Consideration Portion” in its entirety as follows:

“Stock Consideration Portion” shall mean, with respect to each class or series of Company Stock, the number of Parent Common Shares equal to the result of the following calculation:

where “X” is the Stock Consideration Portion; “A” represents the Stock Consideration; “B” represents the Stock Allocation Percentage for the particular class or series of Company Stock; and “C” represents the aggregate number of shares issued and outstanding for such class or series of Company Stock, including any shares issuable upon exercise of options or conversion of warrants for such class or series of Company Stock, as of the Closing Date (but for purposes of clarity with respect to the Common Stock, excluding shares issuable upon conversion of the Preferred Stock). The Stock Consideration Portion for the Series A Preferred Stock shall be the “Series A Preferred Portion.” The Stock Consideration Portion for the Series B Preferred Stock shall be the “Series B

Preferred Portion.” The Stock Consideration Portion for the Series C Preferred Stock shall be the “Series C Preferred Portion.” The Stock Consideration Portion for the Series D Preferred Stock shall be the “Series D Preferred Portion.” The Stock Consideration Portion for the Series E Preferred Stock shall be the “Series E Preferred Portion.” The Stock Consideration Portion for the Common Stock shall be the “Common Stock Portion.”

B. Section 2.1.1 of the Agreement is hereby amended by restating Section 2.1.1 as follows:

Section 2.1.1 Merger of the Company into Merger Sub; Second Step Merger. Upon the terms and subject to satisfaction or waiver of the conditions set forth in this Agreement, and in accordance with the DGCL, at the Effective Time, Merger Sub shall be merged with and into the Company. As a result of the Merger, the separate corporate existence of Merger Sub shall cease and the Company shall continue as the surviving company of the Merger (the “Surviving Corporation”). Following the Effective Time, on the same day of the Effective Time if practicable, but in any case no more than one (1) Business Day following the Effective Time, Parent shall cause the Surviving Corporation to merge with and into a wholly-owned Delaware limited liability company (“Merger Sub 2”) of which Parent shall be the sole member (the “Second Step Merger”). The Merger and the Second Step Merger shall be treated as integrated steps in the transaction contemplated by this Agreement and for any and all federal and state income tax reporting purposes shall be reported as a single “merger transaction” within the meaning of Section 368(a)(1)(A) of the Code.

Any and all other references to or treatment of Merger Sub 2 as a Delaware corporation shall be hereby amended and restated to refer to or treat Merger Sub 2 as a Delaware limited liability company.

D. Section 5.9.8 of the Agreement is hereby amended by restating Section 5.9.8 as follows:

Section 5.9.8 Indebtedness. At the Effective Time, there will be no indebtedness existing between Parent, Merger Sub or Merger Sub 2 and the Company that was issued or acquired, or will be settled, at a discount.

E. Section 5.9.9 of the Agreement is hereby amended by restating Section 5.9.9 as follows:

H. Section 5.9.16 of the Agreement is hereby amended by restating Section 5.9.16 as follows:

Section 5.9.16 Merger Sub Formation. Merger Sub is a newly formed corporation which has conducted no business activities and was formed solely for facilitating the acquisition of the Company. Merger Sub 2 is a newly formed limited liability company which has conducted no business activities and was formed solely for facilitating the acquisition of the Company.

I. Section 5.9.17 of the Agreement is hereby amended by restating Section 5.9.17 as follows:

Section 5.9.17 Control. Parent has no plan or intention to cause Merger Sub 2, after the Second Step Merger, to issue additional membership interests in Merger Sub 2 that would cause Parent to cease to be the sole member of Merger Sub 2.

J. Section 6.15 of the Agreement is hereby amended by restating Section 6.15 as follows:

Section 6.15. Schedule Z. From the Effective Time until the expiration of the Earn-Out Period (i) all Archer Products shall be initially listed on Schedule Z of Parent’s price list (“Schedule Z”) and (ii) the removal of any Archer Product from Schedule Z shall require the joint approval of the Archer Business Unit Manager and the Parent DVTD Manager.
