AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER (this “Agreement”) is made and entered into as of July 28, 2003 by and among Secure Computing Corporation, a Delaware corporation (“Buyer”), Nitro Acquisition Corp., a Washington corporation and wholly-owned subsidiary of Buyer (“Merger Sub”), and N2H2, Inc., a Washington corporation (“Seller”), with respect to the following facts:

A. The respective boards of directors of Buyer, Merger Sub and Seller have approved and declared advisable the merger of Merger Sub with and into Seller (the “Merger”), upon the terms and subject to the conditions set forth herein, and have determined that the Merger and the other transactions contemplated by this Agreement are fair to, and in the best interests of, their respective stockholders.

B. Pursuant to the Merger, among other things, the outstanding shares of Seller Common Stock (“Seller Common Stock”), will be converted into shares of Buyer Common Stock, $0.01 par value (“Buyer Common Stock”), at the rate set forth herein.

C. Simultaneously with the execution and delivery of this Agreement and as a condition and inducement to Buyer’s and Merger Sub’s willingness to enter into this Agreement, each of the members of the Board of Directors and each executive officer of Seller (in their respective capacities as shareholders of Seller) is entering into Voting Agreements with Buyer in the form of Exhibit A attached hereto (the “Seller Voting Agreements”).

D. For United States federal income tax purposes, it is intended that the Merger will qualify as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”).

The parties agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger. At the Effective Time (as defined in Section 1.2) and subject to and upon the terms and conditions of this Agreement and the applicable provisions of Washington Business Corporation Act (“Washington Law”), (i) Merger Sub shall be merged with and into Seller, (ii) the separate corporate existence of Merger Sub shall cease, and (iii) Seller shall be the surviving corporation and a wholly owned subsidiary of Buyer. Seller, as the surviving corporation after the Merger, is hereinafter sometimes referred to as the “Surviving Corporation.”

1.2 Closing; Effective Time. The closing of the Merger and the other transactions contemplated hereby (the “Closing”) will take place at 10:00 a.m., local time, on a date to be specified by the parties (the “Closing Date”), which shall be no later than the second business day after satisfaction or waiver of the conditions set forth in Articles VI and VII, unless another time or date is agreed to by the parties hereto. The Closing shall take place at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇ White & ▇▇▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, or at such other location as the parties hereto shall mutually agree. At the Closing, the parties hereto shall cause the Merger to be consummated by filing the articles of merger substantially in the form of Exhibit B (the “Articles of Merger”) with the Secretary of State of the State of Washington (the “Washington Secretary”), in accordance with the relevant provisions of Washington Law (the time of such filing, or such later time as may be agreed in writing by the parties and specified in the Articles of Merger, being the “Effective Time”). If the Washington Secretary requires any changes in the Articles of Merger as a condition to filing or issuing a certificate to the effect that the Merger is effective, Merger Sub and the Company shall execute any necessary document incorporating such changes, provided such changes are not inconsistent with and do not result in any material change in the terms of this Agreement.

A-1

1.3 Effects of the Merger. The effects of the Merger shall be as provided in this Agreement, the Articles of Merger and the applicable provisions of Washington Law. Without limiting the foregoing, at the Effective Time all the property, rights, privileges, powers and franchises of Seller and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of Seller and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

1.4 Articles of Incorporation; Bylaws.

(a) Subject to Section 5.9, from and after the Effective Time, the articles of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, shall be the articles of incorporation of the Surviving Corporation; provided, however, that at the Effective Time the articles of incorporation of Merger Sub shall be amended so that the name of the Surviving Corporation shall be “N2H2, Inc.”.

(b) Subject to Section 5.9, from and after the Effective Time the bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Corporation.

1.5 Directors and Officers of the Surviving Corporation. The directors and officers of Merger Sub immediately prior to the Effective Time shall serve as the initial directors and officers of the Surviving Corporation, until their respective successors are duly elected or appointed and qualified.

ARTICLE II

CONVERSION OF SHARES

2.1 Conversion of Stock. Pursuant to the Merger, and without any action on the part of the holders of any outstanding shares of capital stock or securities of Seller or Merger Sub:

(a) As of the Effective Time, each share of Seller Common Stock, together with the rights (the “Seller Rights”), if any, associated with each such share issued in connection with the Seller Rights Agreement (the “Seller Rights Plan”) dated May 24, 2002 between Seller and Mellon Investor Services LLC, issued and outstanding immediately prior to the Effective Time (other than shares of Seller Common Stock to be canceled pursuant to Section 2.1(c)), shall be automatically converted into 0.0841 (the “Exchange Ratio”) of a fully paid and nonassessable share of Buyer Common Stock.

(b) As of the Effective Time, each holder of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Seller Common Stock shall cease to have any rights with respect thereto, except the right to receive (i) a certificate (or direct registration) representing the number of whole shares of Buyer Common Stock into which such shares have been converted (the “Buyer Certificates”), and (ii) cash in lieu of fractional shares of Buyer Common Stock in accordance with Section 2.1(f), without interest.

(c) As of the Effective Time, each share of Seller Common Stock held of record immediately prior to the Effective Time by Seller, Merger Sub, Buyer or any Subsidiary (as defined in Section 2.1(g)) of Seller or of Buyer shall be canceled and extinguished without any conversion thereof.

(d) As of the Effective Time, each share of Common Stock, $0.01 par value, of Merger Sub (the “Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall be canceled, extinguished and automatically converted into one validly issued, fully paid and nonassessable share of Common Stock, $0.01 par value, of the Surviving Corporation. Each certificate evidencing ownership of a number of shares of Merger Sub Common Stock shall be deemed to evidence ownership of the same number of shares of Common Stock, $0.01, of the Surviving Corporation.

(e) Without limiting any other provision of this Agreement, the Exchange Ratio shall be adjusted to reflect fully the effect of any stock split, reverse stock split, stock dividend (including any dividend or

A-2

distribution of securities convertible into Buyer Common Stock or Seller Common Stock), extraordinary dividend or distribution, reorganization, reclassification, recapitalization or other like change with respect to Buyer Common Stock or Seller Common Stock occurring or having a record date or an effective date on or after the date hereof and prior to the Effective Time.

(f) No fraction of a share of Buyer Common Stock will be issued by virtue of the Merger. Instead, each holder of shares of Seller Common Stock who would otherwise be entitled to a fraction of a share of Buyer Common Stock (after aggregating all fractional shares of Buyer Common Stock to be received by such holder) shall receive from Buyer an amount of cash (rounded to the nearest whole cent, with .5 being rounded up) equal to the product of (i) such fraction, multiplied by (ii) the Buyer Closing Value. For the purposes of this Agreement, “Buyer Closing Value” shall mean the average of the closing sale prices per share of Buyer Common Stock as reported on the Nasdaq National Market (“Nasdaq”) for each of the five trading days immediately preceding the Effective Time.

(g) For the purposes of this Agreement, the “Exchange Multiple” of any quantity means the product obtained from multiplying such quantity by the Exchange Ratio, and the “Exchange Quotient” of any quantity means the quotient obtained from dividing such quantity by the Exchange Ratio. For purposes of this Agreement, the term “Subsidiary”, when used with respect to any Person, means any corporation or other organization, whether incorporated or unincorporated, of which (A) at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the board of directors or others performing similar functions with respect to such corporation or other organization is directly or indirectly owned or controlled by such Person (through ownership of securities, by contract or otherwise) or (B) such Person or any Subsidiary of such Person is a general partner of any general partnership or a manager of any limited liability company. For the purposes of this Agreement, the term “Person” means any individual, group, organization, corporation, partnership, joint venture, limited liability company, trust or entity of any kind.

2.2 Seller Options, Seller Stock Purchase Plan

(a) As of the Effective Time, Buyer shall, to the full extent permitted by applicable law, assume all of the stock options of Seller outstanding immediately prior to the Effective Time under the Seller Stock Plans (as defined below) (the “Seller Options”). For purposes of this Agreement, “Seller Stock Plans” means the 1997 Stock Option Plan, as amended, 1999 Stock Option Plan, 1999 Nonemployee Director Stock Option Plan, 1999/2000 Transition Stock Option Plan, 2000 Stock Option Plan and the Nonqualified Stock Option Agreement dated August 2, 2002 between the Company and ▇▇▇▇▇▇ ▇▇▇▇▇▇ Welt. Each Seller Option, whether or not exercisable at the Effective Time, shall, to the full extent permitted by applicable law, be assumed by Buyer in such a manner that it shall be exercisable upon the same terms and conditions as under the Seller Stock Plan pursuant to which it was granted and the applicable option agreement issued thereunder (after giving effect to any acceleration of vesting resulting from the Merger on the terms provided under the Seller Stock Plan pursuant to which it was granted and the applicable option agreement issued thereunder); provided that (i) each such option thereafter shall be exercisable for a number of shares of Buyer Common Stock (rounded down to the nearest whole share) equal to the Exchange Multiple of the number of shares of Seller Common Stock subject to such option, and (ii) the option price per share of Buyer Common Stock thereafter shall equal the Exchange Quotient (rounded up to the nearest whole cent, (except that, in the case of Seller Options granted under the 1999 Nonemployee Director Stock Option Plan, the option price per share of Buyer Common Stock shall be carried to at three decimal places, with the last decimal place rounded upwards to the nearest whole number)) of the option price per share of Seller Common Stock subject to such option in effect immediately prior to the Effective Time (the “Buyer Exchange Options”).

(b) Seller shall take all necessary action to amend the Seller Employee Stock Purchase Plan (the “Seller Purchase Plan”) so that (i) the Seller Purchase Plan shall be suspended so that no additional purchase rights shall be issued under it after September 30, 2003, and (ii) each purchase right granted under Seller Purchase Plan shall terminate, if it has not previously terminated by its terms, on the date that the holder thereof enrolls in Secure Computing Corporation Employee Stock Purchase Plan (the “Buyer Purchase Plan”); provided

A-3

that if the purchase date under the Seller Purchase Plan coincides with the enrollment date under the Buyer Purchase Plan, the purchase rights under the Seller Purchase Plan shall not terminate prior to the purchase on such date; and (iii) such other modifications to the Seller Purchase Plan shall be made so as to permit the implementation of this Section 2.2(b). As of the Effective Time, each then-outstanding purchase right granted under the Seller Purchase Plan shall be assumed by Buyer in such a manner that it shall be exercisable upon the same terms and conditions (as amended as described above) as under the Seller Purchase Plan immediately before the Effective Time; provided that each such purchase right shall thereafter be exercisable for whole shares of Buyer Common Stock (rounded down to the nearest whole share) equal to the Exchange Multiple of the number of shares of Seller Common Stock for which such purchase right would otherwise have been exercisable determined as of the relevant grant date under the Seller Purchase Plan at a purchase price per share equal to 85% of the lower of: (i) the Exchange Quotient (rounded up to the nearest whole cent) of the fair market value of a share of Seller Common Stock on the relevant grant date under the Seller Purchase Plan or (ii) the fair market value of a share of a Buyer Common Stock on the relevant purchase date.

2.3 Exchange of Stock Certificates.

(a) At or prior to the Effective Time, Buyer shall enter into an agreement with a bank or trust company selected by Buyer and reasonably acceptable to Seller to act as the exchange agent for the Merger (the “Exchange Agent”).

(b) At or prior to the Effective Time, Buyer shall supply or cause to be supplied to or for the account of the Exchange Agent in trust for the benefit of the holders of Seller Common Stock, for exchange pursuant to this Section 2.3 (i) the Buyer Certificates (or direct registration) evidencing the shares of Buyer Common Stock issuable pursuant to Section 2.1 to be exchanged for outstanding shares of Seller Common Stock, and (ii) cash in an aggregate amount sufficient to make the payments in lieu of fractional shares provided for in Section 2.1(f).

(c) Promptly after the Effective Time, Buyer shall mail or shall cause to be mailed to each Holder (as defined below) a letter of transmittal in customary form and reasonably acceptable to the Seller (which shall specify that delivery shall be effected, and risk of loss and title to the Seller Certificates shall pass, only upon proper delivery of the Seller Certificates to the Exchange Agent) and instructions for surrender of the Seller Certificates. Upon surrender to the Exchange Agent of a Seller Certificate, together with such letter of transmittal duly executed, the Holder shall be entitled to receive in exchange therefor: (i) certificates evidencing that number of shares of Buyer Common Stock issuable to such Holder in accordance with this Article II; (ii) any dividends or other distributions that such Holder has the right to receive pursuant to Section 2.3(d); and (iii) cash in respect of fractional shares as provided in Section 2.1(f), and such Seller Certificate so surrendered shall forthwith be canceled. No certificate representing shares of Buyer Common Stock will be issued to a Person who is not the registered owner of a surrendered Seller Certificate unless (i) the Seller Certificate so surrendered has been properly endorsed or otherwise is in proper form for transfer, and (ii) such Person shall either (A) pay any transfer or other tax required by reason of such issuance or (B) establish to the reasonable satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. Until surrendered in accordance with the provisions of this Section 2.3, from and after the Effective Time, each Seller Certificate shall be deemed to represent, for all purposes other than payment of dividends, the right to receive a certificate representing the number of full shares of Buyer Common Stock as determined in accordance with this Article II and cash in lieu of fractional shares as provided in Section 2.1(f). For purposes of this Agreement, “Seller Certificate” means a certificate which immediately prior to the Effective Time represented shares of Seller Common Stock, and “Holder” means a person who holds one or more Seller Certificates as of the Effective Time.

(d) No dividend or other distribution declared with respect to Buyer Common Stock with a record date after the Effective Time will be paid to Holders of unsurrendered Seller Certificates until such Holders surrender their Seller Certificates. Upon the surrender of such Seller Certificates, there shall be paid to such Holders, promptly after such surrender, the amount of dividends or other distributions, excluding interest, declared with a record date after the Effective Time and not paid because of the failure to surrender Seller Certificates for exchange.

A-4

(e) Notwithstanding anything to the contrary in this Agreement, neither the Exchange Agent, Buyer, the Surviving Corporation nor any party hereto shall be liable to any holder of shares of Seller Common Stock for shares of Buyer Common Stock or cash in lieu of fractional shares delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

2.4 Lost, Stolen or Destroyed Certificates. In the event that any Seller Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue and pay in respect of such lost, stolen or destroyed Seller Certificates, upon the making of an affidavit of that fact by the holder thereof, certificates representing the shares of Buyer Common Stock as may be required pursuant to Section 2.1 and cash in lieu of fractional shares, if any, as may be required pursuant to Section 2.1(f) and any dividends or distributions payable pursuant to Section 2.3(d); provided, however, that Buyer may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Seller Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Buyer or the Exchange Agent with respect to the Seller Certificates alleged to have been lost, stolen or destroyed.

2.5 Tax Consequences. For United States federal income tax purposes, it is intended by the parties hereto that the Merger qualify as a “reorganization” within the meaning of Section 368(a) of the Code and that this Agreement constitutes a “plan of reorganization” within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3.

2.6 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, with respect to each share of Seller Common Stock as to which the holder thereof shall have properly complied with the provisions of Chapter 23B.13 of Washington Law as to dissenters’ rights (each, a “Dissenting Share”), if any, such holder shall be entitled to payment, solely from the Surviving Corporation, of the appraisal value of the Dissenting Shares to the extent permitted by and in accordance with the provisions of Chapter 23B. 13 of Washington Law; provided, however, that (i) if any holder of Dissenting Shares, under the circumstances permitted by and in accordance with Washington Law, affirmatively withdraws such holder’s demand for appraisal of such Dissenting Shares, (ii) if any holder of Dissenting Shares fails to establish such holder’s entitlement to dissenters’ rights as provided in Washington Law or (iii) if any holder of Dissenting Shares takes or fails to take any action the consequence of which is that such holder is not entitled to payment for such holder’s shares under Washington Law, such holder or holders (as the case may be) shall forfeit the right to appraisal of such shares of Seller Common Stock and such shares of Seller Common Stock shall thereupon be deemed to have been converted, as of the Effective Time, into and represent the right to receive the Merger Consideration payable in respect of such shares of Seller Common Stock. The Seller shall give Buyer prompt notice of any demands received by the Seller for appraisal of shares of Seller Common Stock, and Buyer shall have the right to participate in all negotiations and proceedings with respect to such demands. The Seller shall not settle, make any payments with respect to, or offer to settle, any claim with respect to Dissenting Shares without the written consent of Buyer.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF SELLER

Seller makes to Buyer and Merger Sub the representations and warranties contained in this Article III, in each case subject to the exceptions set forth in the disclosure statement, dated as of the date hereof and delivered by Seller to Buyer at least forty-eight (48) hours prior to the execution of this Agreement (the “Seller Disclosure Statement”). The Seller Disclosure Statement shall be arranged in schedules corresponding to the numbered and lettered Sections of this Article III, and the disclosure in any Schedule of the Seller Disclosure Statement shall qualify only the corresponding Section of this Article III.

Each of Seller and the Seller Subsidiaries is duly qualified as a foreign Person to do business, and is in good standing (with respect to jurisdictions that recognize such concept), in each jurisdiction where the character of its owned or leased properties or the nature of its activities makes such qualification necessary, except where the failure to be so qualified or in good standing has not had, or could not reasonably be expected to have, individually or in the aggregate, a Seller Material Adverse Effect.

For the purposes of this Agreement, “Seller Material Adverse Effect” means any material adverse effect on (i) the business, financial condition, results of operations or assets and liabilities, taken as a whole, of Seller, including the Seller Subsidiaries, (ii) the ability of Seller to consummate the Merger or any of the material transactions contemplated by the Agreement or to perform any of its material obligations under the Agreement before the Effective Time, or (iii) Buyer’ ability to vote, receive dividends with respect to or otherwise exercise ownership rights with respect to the stock of the Surviving Corporation. Notwithstanding the foregoing, with respect to item (i) above, none of the following shall be deemed (either alone or in combination) to constitute, and none of the following shall be taken into account in determining whether there has been or will be, a Seller Material Adverse Effect: (A) any adverse change, event or effect arising from or relating to general business or economic conditions; (B) any adverse change, event or effect relating to or affecting the Internet filtering and monitoring industry generally, which does not disproportionately affect Seller; and (C) any adverse change, event or effect arising from or relating to the announcement or pendency of the Merger and the other transactions contemplated by this Agreement.

Buyer and each Buyer Subsidiary are duly qualified as a foreign Person to do business, and are each in good standing, in each jurisdiction where the character of its owned or leased properties or the nature of its activities makes such qualification necessary, except where the failure to be so qualified or in good standing has not had, or could not reasonably be expected to have, individually and in the aggregate, a Buyer Material Adverse Effect.

For the purposes of this Agreement, “Buyer Material Adverse Effect” means a material adverse effect on (i) the business, financial condition, results of operations or assets and liabilities, taken as a whole, of Buyer, including the Buyer Subsidiaries, or (ii) the ability of Buyer to consummate the Merger or any of the material transactions contemplated by the Agreement or to perform any of its material obligations under the Agreement before the Effective Time.

Neither the execution and delivery of the Agreement, nor the consummation of the Merger or the other transactions contemplated hereby, nor compliance by Buyer and Merger Sub with all of the provisions hereof and thereof will, (i) conflict with or result in any breach of any provision of the certificate of incorporation, bylaws or other charter documents of Buyer or any Buyer Subsidiary, (ii) violate any order, writ, injunction, decree, statute, rule or regulation applicable to Buyer or any Buyer Subsidiary, or by which any of their properties or assets may be bound, or (iii) result in a violation or breach of, or constitute (with or without due notice or lapse of time or both) a default under, or result in any material change in, or give rise to any right of termination, cancellation, acceleration, redemption or repurchase under, any of the terms, conditions or provisions of any Buyer Contract (as defined below), except in the case of clauses (ii) or (iii), for any violation, breach or default that has not had, or could not reasonably be expected to have, a Buyer Material Adverse Effect.

For purposes of this Agreement, “Acquisition Proposal” with respect to an entity shall mean any offer or proposal (other than an offer or proposal by the other party) relating to any Acquisition Transaction. For purposes of this Agreement, “Acquisition Transaction” shall mean any transaction or series of related transactions involving: (A) any purchase from the entity or acquisition by any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a 15% interest in the total outstanding voting securities of the entity or of any Subsidiary or any tender offer or exchange offer that if consummated would result in any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) beneficially owning 15% or more of the total outstanding voting securities of the entity or of any Subsidiary or any merger, consolidation, business combination or similar transaction involving the entity; (B) any sale, lease (other than in the ordinary course of business), exchange, transfer, license

In addition to the obligations of Seller set forth in this Section 5.3, Seller shall promptly (and in no event later than twenty-four (24) hours after receipt of any Acquisition Proposal, any inquiry or indication of interest that Seller reasonably believes could lead to an Acquisition Proposal) advise Buyer orally and in writing of any Acquisition Proposal or any request for nonpublic information or inquiry which Seller reasonably believes would lead to an Acquisition Proposal or to any Acquisition Transaction, the material terms and conditions of such Acquisition Proposal, request or inquiry, and the identity of the person or group making any such Acquisition Proposal, request or inquiry. Seller will keep Buyer informed as promptly as practicable in all material respects of the status and details (including material amendments or proposed material amendments) of any such Acquisition Proposal, request or inquiry made after the date hereof.

5.4 Access to Information. From the date of this Agreement until the Effective Time, each of Buyer and Seller will afford to the other party and its authorized representatives (including counsel, financial advisors, consultants, accountants, auditors and agents) reasonable access during normal business hours and upon reasonable notice to all of its facilities, personnel and operations and to all of its and its Subsidiaries books and records, will permit the other party and its authorized representatives to conduct inspections as they may reasonably request and will instruct its officers and those of its Subsidiaries to furnish the other party with such financial and operating data and other information with respect to its business and properties as the other party may from time to time reasonably request, subject to the restrictions set forth in the Confidentiality Agreement, dated as of February 12, 2003 between Buyer and Seller (the “Confidentiality Agreement”). Buyer and Seller agree that each of them will treat any such information in accordance with the Confidentiality Agreement, which shall remain in full force and effect in accordance with its terms.

5.5 Special Meeting; Registration Statement; Board Recommendations.

(a) Promptly after the date hereof, Seller will take all action necessary in accordance with Washington Law and its articles of incorporation and bylaws to convene a meeting of Seller’s shareholders to consider adoption and approval of this Agreement and approval of the Merger (the “Seller Special Meeting”) to be held as promptly as possible, and in any event (to the extent permissible under applicable law) within 40 days after the declaration of effectiveness of the Registration Statement. Subject to Section 5.5(e), Seller will use its commercially reasonable efforts to solicit from its shareholders proxies in favor of the adoption and approval of this Agreement and the approval of the Merger and will take all other action necessary or advisable to secure the vote or consent of its shareholders required by Washington Law to obtain such approvals. Notwithstanding anything to the contrary contained in this Agreement, Seller may adjourn or postpone the Seller Special Meeting to the extent necessary to ensure that any necessary supplement or amendment to the Proxy Statement/Prospectus is provided to Seller’s shareholders in advance of a vote on the Merger and this Agreement or, if as of the time for which the Seller Special Meeting is originally scheduled (as set forth in the Proxy Statement/Prospectus) there are insufficient shares of Seller Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Seller Special Meeting. Seller shall ensure that the Seller Special Meeting is called, noticed, convened, held and conducted, and that all proxies solicited by Seller in connection with the Seller Special Meeting are solicited in compliance with the Washington Law and the Exchange Act, Seller’s articles of incorporation and bylaws and all other applicable legal requirements.

(b) Subject to Section 5.5(c): (i) the board of directors of Seller shall recommend that Seller’s shareholders vote in favor of and adopt and approve this Agreement and approve the Merger at the Seller Special Meeting; (ii) the Proxy Statement/Prospectus shall include a statement to the effect that the board of directors of Seller has recommended that Seller’s shareholders vote in favor of and adopt and approve this Agreement and the Merger at the Seller Special Meeting; and (iii) neither the board of directors of Seller nor any committee thereof shall withdraw, amend or modify, or propose or resolve to withdraw, amend or modify in a manner adverse to Buyer, the recommendation of the board of directors of Seller that Seller’s shareholders vote in favor of and adopt and approve this Agreement and the Merger.

A-27

(c) If prior to the Effective Time the board of directors of Seller determines in good faith, after consultation with its financial and legal advisors, that any Acquisition Proposal constitutes a Seller Superior Offer and the board of directors of Seller believes in its good faith judgment, after receiving advice of its outside legal counsel that failing to take such action with respect to the Seller Superior Offer would constitute a breach of its fiduciary duties under applicable law, nothing in this Agreement shall prevent the board of directors of Seller from withholding, withdrawing, amending or modifying its recommendation in favor of the Merger; provided, that (i) a Seller Superior Offer is made to Seller and is not withdrawn, (ii) Seller shall have provided written notice to Buyer (a “Seller Notice of Superior Offer”) advising Buyer that Seller has received a Seller Superior Offer, specifying the material terms and conditions of such Seller Superior Offer and identifying the person or entity making such Superior Offer, (iii) Buyer shall not have, within three (3) business days of Buyer’s receipt of the Seller Notice of Superior Offer, made an offer that Seller board of directors by a majority vote determines in its good faith judgment (after consultation with its financial advisor) to be at least as favorable to Seller’s shareholders as such Seller Superior Offer (it being agreed that the Seller board of directors shall convene a meeting to consider any such offer by Buyer promptly following the receipt thereof). Seller shall provide Buyer with at least three (3) business days prior notice of any meeting of Seller’s board of directors at which Seller’s board of directors is reasonably expected to consider any Acquisition Transaction. For purposes of this Agreement “Seller Superior Offer” shall mean an unsolicited, bona fide written offer or proposal made by a third party to consummate any of the following transactions: (i) a merger or consolidation involving Seller pursuant to which the shareholders of Seller immediately preceding such transaction hold less than a majority of the equity interest in the surviving or resulting entity of such transaction, (ii) the acquisition by any person or group (including by way of a tender offer or an exchange offer or a two step transaction involving a tender offer followed with reasonable promptness by a merger involving Seller), directly or indirectly, of ownership of 51% of the then outstanding shares of capital stock of Seller, or (iii) any sale, transfer or disposition of all or substantially all of the assets of Seller, on terms that the board of directors of Seller determines, in its reasonable judgment (after consultation with its financial advisor) to be more favorable to its shareholders than the terms of the Merger; provided, however, that any such offer shall not be deemed to be a “Seller Superior Offer” if any financing required to consummate the transaction contemplated by such offer is not committed and is not likely in the reasonable judgment of Seller’s board of directors (after consultation with its financial advisor) to be obtained by such third party on a timely basis.

(d) Nothing contained in this Agreement shall prohibit Seller or its board of directors from taking and disclosing to its shareholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act.

(e) As promptly as practicable after the execution of this Agreement, Seller and Buyer shall mutually prepare, and Buyer shall file the Registration Statement with the SEC. As promptly as practicable following receipt of SEC comments on such Registration Statement, Buyer and Seller shall mutually prepare a response to such comments. Buyer and Seller shall use all commercially reasonable efforts to have the Registration Statement declared effective by the SEC as promptly as practicable. Buyer shall also take any action required to be taken under applicable state blue sky or securities laws in connection with Buyer Common Stock to be issued in exchange for the shares of Seller Common Stock. Buyer and Seller shall promptly furnish to each other all information, and take such other actions (including without limitation using all commercially reasonable efforts to provide any required consents of their respective independent auditors), as may reasonably be requested in connection with any action by any of them in connection with the preceding sentences of this Section 5.5(e). Whenever any party learns of the occurrence of any event which is required to be set forth in an amendment or supplement to the Proxy Statement/Prospectus, the Registration Statement or any other filing made pursuant to this Section 5.5(e), Buyer or Seller, as the case may be, shall promptly inform the other of such occurrence and cooperate in filing with the SEC or its staff and/or mailing to shareholders of Seller such amendment or supplement.

5.8 Notification of Certain Matters. Seller shall give prompt notice to Buyer and Merger Sub, and Buyer and Merger Sub shall give prompt notice to Seller, of (i) the occurrence or nonoccurrence of any event the occurrence or nonoccurrence of which would be likely to cause any representation or warranty contained in this Agreement to be untrue or inaccurate in any material respect at or prior to the Effective Time, (ii) any material failure of Seller, Buyer or Merger Sub, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder, (iii) any notice or other communication from any third party alleging that the consent of such third party is or may be required in connection with the transactions contemplated by this Agreement, or (iv) any facts or circumstances arise that could reasonably be expected to result in a Seller Material Adverse Effect or a Buyer Material Adverse Effect, as the case may be.

5.9 Indemnification.

(a) The Articles of Incorporation and Bylaws of the Surviving Corporation will contain, and Buyer will cause the Surviving Corporation to honor, the provisions with respect to indemnification set forth in the Articles of Incorporation and Bylaws of Seller immediately prior to the Effective Time, which provisions will not be amended, repealed or otherwise modified for a period of six (6) years after the Effective Time in any manner that would adversely affect the rights thereunder of individuals who at the Effective Time were directors, officers, employees or agents of Seller, unless such modification is required by law.

(b) Buyer will cause the Surviving Corporation to honor and fulfill the obligations of Seller and Buyer pursuant to any indemnification agreements with Seller’s directors and officers and Buyer’ directors and officers existing at or before the Effective Time.

A-29

premium for such coverage exceeds such amount, Buyer or the Surviving Corporation will purchase a policy with the greatest coverage available for such amount.

third party has publicly announced an Acquisition Proposal with respect to Seller and within 12 months following the termination of this Agreement, a Seller Acquisition (as hereinafter defined) is consummated or Seller enters into an agreement providing for a Seller Acquisition by such third party, Seller shall pay Buyer the Seller Termination Fee, less any Buyer Expenses previously paid pursuant to Section 8.3(b)(iii) below.

The parties agree as follows:

(a) “Beneficially Own” or “Beneficial Ownership” with respect to any securities means having “beneficial ownership” of such securities as determined pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Without duplicative counting of the same securities by the same holder, securities Beneficially Owned by a person include securities Beneficially Owned by all other persons with whom such person would constitute a “group” within the meaning of Section 13(d) of the Exchange Act with respect to the securities of the same issuer.

(b) “Existing Shares” means all issued and outstanding shares of Seller Common Stock owned of record or Beneficially Owned by Shareholder and over which Shareholder has voting control as of the record date for persons entitled (i) to receive notice of, and to vote at, a meeting of the shareholders of Seller called for purposes of voting on the Merger Agreement and the Merger, or (ii) to take action by written consent of the shareholders of Seller with respect to the Merger Agreement and the Merger.

(c) “Voting Period” means the period commencing on the date of this Agreement and continuing until the termination of this Agreement.

2. Representations and Warranties of Shareholder. Shareholder represents and warrants to Buyer as follows:

(a) On the date hereof, Shareholder Beneficially Owns the outstanding shares of Seller Common Stock set forth on the signature page hereto and holds stock options and warrants to purchase the number of shares of Seller Common Stock set forth on the signature page hereto. On the date hereof, such shares constitute all of the outstanding shares of Seller Common Stock Beneficially Owned by Shareholder and all of the shares of Seller Common Stock subject to stock options or warrants held by Shareholder. On the date hereof, there are no outstanding options or other rights to acquire from Shareholder, or obligations of Shareholder to sell, any shares of Seller Common Stock. Except as permitted by this Agreement, the shares of Seller Common Stock set forth on the signature page hereto are held by Shareholder, or by a nominee or custodian for the benefit of Shareholder, free and clear of all mortgages, claims, charges, liens, security interests, pledges, options, proxies, voting trusts or agreements (“Encumbrances”), except for any such Encumbrances arising hereunder.

(c) Except for any applicable filings under federal and state securities laws, no filing with, and no permit, authorization, consent or approval of, any Governmental Entity is required to be made or obtained by Shareholder for the execution of this Agreement by Shareholder or compliance by Shareholder with the provisions hereof. Neither the execution and delivery of this Agreement by Shareholder nor the compliance by Shareholder with the provisions hereof will (i) result in a violation or breach of, or constitute (with or without notice or lapse of time or both) a default (or give rise to any third party right of termination, cancellation, acceleration, redemption or purchase) under any of the terms, conditions or provisions of any note, bond, mortgage, indenture, deed of trust, license, lease, agreement or other instrument or obligation to which Shareholder is a party or by which Shareholder or any of Shareholder’s properties or assets is bound, or (ii) violate any order, writ, injunction, decree, judgment, statute, rule or regulation applicable to Shareholder or any of the Existing Shares.

(d) Shareholder understands and acknowledges that Buyer is entering into, and causing Merger Sub to enter into, the Merger Agreement in reliance upon Shareholder’s concurrent execution and delivery of this Agreement.

3. Representations And Warranties Of Buyer. Buyer hereby represents and warrants to Shareholder as follows:

(a) Buyer has the corporate power and authority to enter into and perform all of its obligations under this Agreement. This Agreement has been duly and validly executed and delivered by Buyer and constitutes a valid and binding agreement of Buyer, enforceable against Buyer in accordance with its terms, except to the extent that its enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting the enforcement of creditors’ rights generally or by general equitable principles.

(b) Except for filings under the Exchange Act, no filing with, and no permit, authorization, consent or approval of, any Government Entity is necessary for the execution of this Agreement by Buyer. Neither the execution and delivery of this Agreement by Buyer nor compliance by Buyer with any of the provisions hereof shall (i) conflict with or result in any breach of any organizational documents of Buyer, (ii) result in a violation or breach of, or constitute (with or without notice or lapse of time or both) a default (or give rise to any third party right of termination, cancellation, acceleration, redemption or purchase) under any of the terms, conditions or provisions of any note, bond, mortgage, indenture, deed of trust, license, lease, agreement or other instrument or obligation of any kind to which Buyer is a party or by which Buyer or any of its properties or assets is bound, or (iii) violate any order, writ, injunction, decree, judgment, statute, rule or regulation applicable to Buyer or any of its properties or assets.

4. Disclosure. Shareholder hereby agrees to permit Buyer to publish and disclose in the Registration Statement and the Proxy Statement/Prospectus (including all documents and schedules filed with the SEC), and in any press release or other disclosure document which Buyer reasonably determines to be necessary or desirable to comply with applicable law or the rules and regulations of The Nasdaq Stock Market in connection with the Merger and any transactions related thereto, Shareholder’s identity and ownership of Seller Common Stock and the nature of Shareholder’s commitments, arrangements and understandings under this Agreement, provided that any public announcement or disclosure is made in accordance with the terms of the Merger Agreement.

5. Voting Agreement. Shareholder hereby irrevocably and unconditionally agrees that, during the period commencing on the date hereof and continuing until the first to occur of the Effective Time or termination of this Agreement, Shareholder will appear (in person or by proxy) at any meeting (whether annual or special and whether or not an adjourned or postponed meeting) of the holders of Seller Common Stock, however called, or otherwise cause the Existing Shares then Beneficially Owned by Shareholder to be counted as present thereat for purposes of establishing a quorum, and (b) Shareholder will vote or provide a written consent with respect to the Existing Shares (or will cause the Existing Shares to be voted, or cause a written consent to be provided with respect to the Existing Shares) in favor of the Merger. Shareholder will also vote or provide a written consent with respect to the Existing Shares (or will cause the Existing Shares to be voted, or cause a written consent to be provided with respect to the Existing Shares) against any action, proposal, transaction or agreement that would result in a breach in any respect of any covenant, representation or warranty or any other obligation or agreement of Seller contained in the Merger Agreement. Shareholder agrees not to enter into any agreement or commitment with any Person the effect of which would be inconsistent with or violative of the provisions and agreements contained in this Section 5.

6. Grant of Irrevocable Proxy; Further Assurances.

(a) Shareholder hereby appoints Buyer and any designee of Buyer, and each of them individually, as such Shareholder’s proxy and attorney-in-fact, with full power of substitution and resubstitution, to vote or act by written consent during the Voting Period with respect to the Existing Shares in accordance with Section 5. This proxy is given to Buyer to secure the performance of the duties of Shareholder under this Agreement. Shareholder shall promptly cause a copy of this Agreement to be deposited with Seller at its principal place of business. Shareholder shall take further action or execute such other instruments as may be necessary to effectuate the intent of this proxy.

(b) The proxy and power of attorney granted pursuant to Section 6(a) by Shareholder shall be irrevocable during the term of this Agreement, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy and shall revoke any and all prior proxies granted by such Shareholder.

(d) Neither this Agreement nor any right, interest or obligation hereunder shall be assigned by either of the parties hereto without the prior written consent of the other party. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. This Agreement is not intended to confer any rights or remedies hereunder upon any other person except the parties hereto.

(e) This Agreement shall be governed by the laws of the State of Washington without reference to principles of conflicts of law.

(f) This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

(g) In case any one or more of the provisions contained in this Agreement should be finally determined to be invalid, illegal or unenforceable in any respect against a party hereto, it shall be adjusted if possible to effect the intent of the parties. In any event, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, and such invalidity, illegality or unenforceability shall only apply as to such party in the specific jurisdiction where such final determination shall have been made.

(h) The article and section headings contained in this Agreement are solely for the purpose of reference and shall not in any way affect the meaning or interpretation of this Agreement. The word “including” shall be deemed to mean “including without limitation.”

(i) This Agreement embodies the entire agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no representations, promises, warranties, covenants, or undertakings, other than those expressly set forth or referred to herein and therein.

(j) When used in this Agreement “law” refers to any applicable law (whether civil, criminal or administrative) including, without limitation, common law, statute, statutory instrument, treaty, regulation, directive, decision, code, order, decree, injunction, resolution or judgment of any government, quasi-government, supranational, federal, state or local government, statutory or regulatory body, court, or agency.

(k) Each of the parties hereto recognizes and acknowledges that a breach by it of any covenants or agreements contained in this Agreement will cause the other party to sustain damages for which it would not have an adequate remedy at law for money damages. Therefore, in the event of any such breach, the aggrieved party shall be entitled to the remedy of specific performance of such covenants and agreements and injunctive and other equitable relief in addition to any other remedy to which it may be entitled, at law or in equity.

(l) All costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses.

(m) Notwithstanding any other provision of this Agreement (including, without limitation, Section 5 hereof), nothing contained in this Agreement shall bind or obligate Shareholder to act or refrain from acting in any capacity other than as a shareholder of Seller, it being expressly understood and agreed that this Agreement shall not bind or obligate Shareholder in his capacity as a director or officer of Seller.

(n) Each party to this Agreement has been represented by counsel during the preparation and execution of this Agreement, and therefore waives any rule of construction that would construe ambiguities against the party drafting the agreement.
