Any Transfer (other than a Permitted Transfer) of Shares in breach or violation of this Agreement shall be void and of no force or effect.

(f)In the event that any Shareholder acquires Beneficial Ownership of Shares (or any right or interest therein) after the execution of this Agreement, such Shareholder shall promptly deliver to Parent and the Company a written notice indicating the number of such Shares (or right or interest therein) acquired or received, and the number of Shares held by such Shareholder set forth on Exhibit A hereto will be deemed amended accordingly and such Shares (or right or interest therein) shall automatically become Covered Shares subject to the terms of this Agreement.

15.Miscellaneous.

(y)Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect.

(z)Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned or transferred, in whole or in part, by operation of Law or otherwise by any of the parties hereto without the prior written consent of the other parties.

Accordingly, the parties acknowledge and agree that Parent and the Company shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which they are entitled at law or in equity.

(ii)Each of the parties agrees that, (i) the seeking of remedies by Parent or the Company pursuant to this Section 15(d) shall not in any way constitute a waiver by any party seeking such remedies of its right to seek any other form of relief that may be available to it under this Agreement, including in the event that the remedies provided for in this Section 15(d) are not available or otherwise are not granted and (ii) no party shall require the other to post any bond or other security as a condition to institute any Legal Action for specific performance under this Section 15(d).

(iii)Notwithstanding anything to the contrary in this Agreement, the parties hereto acknowledge and agree that no breach of any representation or warranty contained in this Agreement shall give rise to the failure of any condition to the Merger to be satisfied or the right of any party to terminate the Merger Agreement.

8

The parties hereto agree that their respective representations, warranties and covenants (if any) set forth in this Agreement are solely for the benefit of the other parties hereto, in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person other than the parties hereto any rights or remedies hereunder.

(ae)Governing Law. This Agreement, and all Legal Actions (whether based on contract, tort, or statute) arising out of, relating to, or in connection with this Agreement or the actions of any of the parties hereto in the negotiation, administration, performance, or enforcement hereof, shall be governed by and construed in accordance with the internal laws of the State of Washington without giving effect to any choice or conflict of law provision or rule (whether of the

State of Washington or any other jurisdiction) that would cause the application of Laws of any jurisdiction other than those of the State of Washington.

(af)Consent to Jurisdiction; Waiver of Jury Trial.

(i)Each of the parties irrevocably agrees that any Legal Action arising out of or relating to this Agreement brought by any other party or its successors or assigns shall be brought and determined exclusively in any state or federal court within the State of Washington. Each of the parties hereby irrevocably submits to the exclusive jurisdiction of such Washington courts for itself and with respect to its property, generally and unconditionally, with regard to any such Legal Action arising out of or relating to this Agreement. Each of the parties agrees not to commence any Legal Action relating thereto except in the courts described above in Washington, other than actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court in Washington as described in this Agreement. Each of the parties further agrees that notice as provided herein shall constitute sufficient service of process, and the parties further waive any argument that such service is insufficient. Each of the parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any Legal Action arising out of or relating to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the courts in the State of Washington, as described in this Agreement, for any reason, (ii) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) that (A) the Legal Action in any such court is brought in an inconvenient forum, (B) the venue of such Legal Action is improper or (C) this Agreement, or the subject matter of this Agreement, may not be enforced in or by such courts.

(ii)EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THE FOREGOING WAIVER, (III) IT MAKES THE FOREGOING WAIVER VOLUNTARILY, AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 15(h)(II).

(ag)Entire Agreement. This Agreement and the documents and instruments and other agreements contemplated herein constitute the entire agreement of the parties and supersede all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter of this Agreement.

(ah)Mutual Drafting; Interpretation. Each party hereto has participated in the drafting of this Agreement, which each party acknowledges is the result of extensive negotiations between the parties. If an ambiguity or question of intent or

10

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. For purposes of this Agreement, whenever the context requires, the singular number shall include the plural, and vice versa. As used in this Agreement, the words "include" and "including," and words of similar meaning, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words "without limitation." Except as otherwise indicated, all references in this Agreement to "Sections" and "Exhibits" are intended to refer to Sections of this Agreement and the Exhibits to this Agreement. The term "or" shall not be deemed to be exclusive. The words "hereof," "herein" and "hereunder" and words of similar import, when used in this Agreement, refer to this Agreement as a whole and not to any particular provision of this Agreement. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

(ai)Expenses. All costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such expense, regardless of whether the Merger is consummated.

(aj)Counterparts. This Agreement may be executed in two or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. The exchange of a fully executed Agreement (in counterparts or otherwise) by electronic delivery in .pdf format or through other electronic means shall be sufficient to bind the parties to the terms and conditions of this Agreement.
