(A) If the Plexus Stock Value is equal to or greater than $30.00, and equal to or less than $37.50, the Exchange Rate shall be 0.4000 shares of Plexus Common Stock for each share of SeaMED Common Stock.

(ii) Any shares of SeaMED Common Stock that are owned by SeaMED at the Effective Time of Merger shall be canceled and retired and cease to exist and no Plexus Common Stock or other consideration shall be issued or delivered in exchange therefor. Any shares of SeaMED Common Stock as to which the holders thereof have perfected dissenter's rights under the WBCA shall be treated as provided in Section 2.11 of this Agreement. (b) Adjustment. In the event that, prior to the Effective Time of Merger, there is a reclassification, stock split or stock dividend with respect to outstanding Plexus Common Stock or outstanding SeaMED Common Stock, appropriate and proportionate adjustment, if any, shall be made to the Exchange Rate. 2.7 Conversion of Acquisition Common Stock. At the Effective Time of Merger, and without any action on the part of the holders of common stock of Acquisition, each share of common stock of Acquisition issued and outstanding at the Effective Time of Merger shall be converted into one (1) share of SeaMED Common Stock. 2.8 Exchange of SeaMED Certificates. (a) Exchange Agent. As of the Effective Time of Merger, Plexus shall deposit, or shall cause to be deposited, with the corporate trust department of Firstar Bank NA, Milwaukee, Wisconsin, or such other bank or trust company designated by Plexus and approved by SeaMED, which approval shall not be unreasonably withheld (the "Exchange Agent"), for the benefit of the SeaMED Shareholders, for exchange in accordance with this Article II of this -8- 15 Agreement through the Exchange Agent, certificates representing the shares of Plexus Common Stock (such certificates for shares of Plexus Common Stock, together with any dividends or distributions with respect thereto and together with any cash for fractional share interests made pursuant to Section 2.8(e) of this Agreement, being hereinafter referred to as the "Exchange Fund") issuable pursuant to Section 2.6 of this Agreement in exchange for outstanding shares of SeaMED Common Stock. (b) Exchange Procedures. (i) At or promptly after the Effective Time of Merger, Plexus shall (i) cause the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time of Merger represented outstanding shares of SeaMED Common Stock (the "SeaMED Certificates"): (A) a letter of transmittal which shall be in such form and have such provisions as Plexus may reasonably specify; and (B) instructions to effect the surrender of the SeaMED Certificates in exchange for certificates representing shares of Plexus Common Stock; and (ii) direct the Exchange Agent to issue certificates representing that number of whole shares of Plexus Common Stock to which each holder of uncertificated shares of SeaMED Common Stock (as reflected on the books and records of SeaMED's transfer agent) is entitled pursuant to the provisions of this Article II of this Agreement, without any action on the part of such holders, plus any cash in lieu of any fractional share interest in accordance with Section 2.8(e) of this Agreement. (ii) Upon surrender of a SeaMED Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly executed, and with such other documents as the Exchange Agent may reasonably require, the holder of such SeaMED Certificate shall be entitled to receive, and Plexus shall cause the Exchange Agent to promptly deliver in exchange therefor, a certificate representing that number of whole shares of Plexus Common Stock to which such holder is entitled in respect of such SeaMED Certificate pursuant to the provisions of this Article II of this Agreement, plus any cash in lieu of any fractional share interest in accordance with Section 2.8(e) of this Agreement, and the SeaMED Certificate so surrendered shall forthwith be canceled; provided, however, that fractional share interests of any one holder shall be aggregated to maximize the number of whole shares of Plexus Common Stock to be issued and minimize the fractional interests to be paid in cash as provided in Section 2.8(e) of this Agreement. (iii) In the event of a transfer of ownership of shares of SeaMED Common Stock which is not registered in the transfer records of SeaMED, a certificate representing the proper number of shares of Plexus Common Stock, and any cash in lieu of any fractional share interests in accordance with Section 2.8(e) of this Agreement, shall be delivered to the transferee if the SeaMED Certificate which represented such shares of SeaMED Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. (iv) Until surrendered as contemplated by this Section 2.8 of this Agreement, each SeaMED Certificate shall be deemed at all times after the Effective Time of Merger to represent only the right to receive upon surrender a certificate representing shares of -9- 16 Plexus Common Stock and cash in lieu of any fractional share interest as contemplated by Section 2.8(e) of this Agreement, or in respect of dissenting shares, the consideration determined pursuant to Section 2.11 of this Agreement. (c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time of Merger with respect to Plexus Common Stock with a record date after the Effective Time of Merger shall be paid to the holder of any unsurrendered SeaMED Certificate with respect to the shares of Plexus Common Stock represented thereby, and no cash payment in lieu of a fractional share shall be paid to any such holder pursuant to Section 2.8(e) of this Agreement, until the holder of such SeaMED Certificate has surrendered such SeaMED Certificate to the Exchange Agent. Subject to the effect of any applicable Law, following the surrender of any such SeaMED Certificate, there shall be paid to the holder of the certificate representing whole shares of Plexus Common Stock issued in exchange for the surrendered SeaMED Certificates, without interest: (i) promptly, the amount of any cash payable with respect to a fractional share interest to which such holder is entitled pursuant to Section 2.8(e) of this Agreement and the amount of dividends or other distributions with a record date after the Effective Time of Merger theretofore paid with respect to such whole shares of Plexus Common Stock; and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time of Merger but prior to surrender and a payment date occurring after surrender payable with respect to such whole shares of Plexus Common Stock. (d) No Further Rights in SeaMED Common Stock. All shares of Plexus Common Stock issued upon conversion of the SeaMED Common Stock in accordance with the terms of this Agreement (and any cash paid pursuant to Section 2.8(e) of this Agreement) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the SeaMED Common Stock. (e) No Fractional Shares. No fractional shares of Plexus Common Stock shall be issued in the Merger. All fractional share interests of a holder of more than one SeaMED Certificate at the Effective Time of Merger shall be aggregated. If a fractional share interest results after such aggregation, each holder of a fractional share interest shall be paid an amount in cash equal to the product obtained by multiplying such fractional share interest by the Plexus Stock Value. Promptly after the determination of the amount of cash, if any, to be paid to holders of fractional share interests, the Exchange Agent shall notify Plexus and Plexus shall direct the Exchange Agent to deliver such amounts to such holders in accordance with Section 2.8(b) of this Agreement, subject to and in accordance with the terms of Section 2.8(c) of this Agreement. (f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the SeaMED Shareholders after twelve (12) months after the Effective Time of Merger shall be delivered to Plexus, upon demand, and any SeaMED Shareholders who have not theretofore complied with this Article II of this Agreement shall thereafter look only to Plexus for payment of their claim for shares of Plexus Common Stock, any cash in lieu of fractional share interests and any dividends or distributions with respect to Plexus Common Stock. -10- 17 (g) No Liability. Neither the Exchange Agent nor any party to this Agreement shall be liable to any SeaMED Shareholder for any shares of SeaMED Common Stock or Plexus Common Stock (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to any abandoned property, escheat or similar Law. (h) Withholding Rights. Subject to the following sentences of this Section 2.8(h), Plexus shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any SeaMED Shareholder such amounts as Plexus is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax Law. If withholding is required for anything other than back up withholding on cash payments, Plexus will notify SeaMED and provide SeaMED the right to provide an opinion of legal counsel that no withholding is covered. To the extent that amounts are withheld by Plexus, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the SeaMED Shareholder in respect of which such deduction and withholding was made by Plexus. 2.9 Stock Transfer Books.

At or prior to the Effective Time of Merger, Plexus shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Plexus Common Stock for delivery upon exercise of SeaMED Options assumed by it in accordance with this Section 2.12 of this Agreement. As soon as practicable after the Effective Time of Merger, Plexus shall file a registration statement (or a post-effective amendment to the registration statement) on Form S-8 (or any successor or other appropriate form) with respect to the Plexus Common Stock subject to such SeaMED Options, and shall use its best efforts to maintain the effectiveness of such registration statement (and maintain the current status of the prospectus or prospectuses relating thereto) for so long as such SeaMED Options remain outstanding. 2.13 Voting Agreements.

From and after the date hereof until the earlier of the Effective Time of Merger or termination of the Agreement, subject to the proviso in the next paragraph, SeaMED agrees that neither it nor any of its officers and directors shall, and that SeaMED shall direct and use its reasonable best efforts to cause its employees, agents and representatives (including any investment banker, attorney or accountant retained by it) (such officers, directors, employees, agents and representatives sometimes collectively referred to herein as "Representatives") not to, directly or indirectly, initiate, solicit, encourage or otherwise facilitate any inquiries or the making of any proposal or offer with respect to an Other Transaction (any such proposal or offer being herein after referred to as a "Takeover Proposal"). SeaMED further agrees that neither it nor its Representatives shall directly or indirectly, engage in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any Person relating to a an Other Proposal or Takeover Proposal, whether made before or after the date of this Agreement, or otherwise facilitate any effort or attempt to make or implement a Takeover Proposal; PROVIDED, HOWEVER, that nothing contained in this Agreement shall prevent SeaMED or SeaMED's Board of Directors from: (a) complying with Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act with regard to a Takeover Proposal; (b) providing information in response to a request therefor by a Person if the Person making the inquiry makes the following representations, and SeaMED has no reason to believe that the representations are not true, that: (i) the inquiry is made in good faith, (ii) to the knowledge of such Person, the inquiry has not been solicited by SeaMED or its Representatives in breach of Section 3.9(c) hereof; (iii) the Person has reviewed the terms of this Agreement; and (iv) subject to due diligence on the information received from SeaMED, the Person requesting the information expects that if it makes an offer to SeaMED it would be a Superior Proposal; provided that the Person so requesting such information must also (y) execute a confidentiality agreement on terms substantially equivalent to those contained in the Confidentiality Agreement and (z) submit with such inquiry a nonrefundable, good faith deposit in the form of a check payable to SeaMED in the amount of $50,000, which shall be paid to Plexus in the event that this Agreement is terminated by Plexus pursuant to Section 9.1(c)(v), (vi), (vii) or (viii); (c) engaging in any negotiations or discussions with any Person who has made an unsolicited bona fide Takeover Proposal; or (d) withdrawing or modifying the approval or recommendation by SeaMED's Board of Directors of this Agreement and the Merger in connection with recommending an unsolicited bona fide written Takeover Proposal to the stockholders of SeaMED or entering into any agreement with respect to an unsolicited bona fide written Takeover Proposal; IF AND ONLY TO THE EXTENT THAT, both (i) in each such case referred to in clause (b), (c) or (d) above, SeaMED's Board of Directors determines in good faith after receipt of written advice from outside legal counsel experienced in such matters that such action is necessary in order for its directors to comply with their respective fiduciary duties under applicable law; and either (ii) in each case referred to in clause (c) or (d) above, SeaMED's Board of Directors -16- 23 determines in good faith (after consultation with its financial advisor) that such Takeover Proposal, if accepted, is reasonably likely to be consummated, taking into account all legal, financial and regulatory aspects of the proposal and the Person making the proposal and would, if consummated, result in a transaction superior to the transaction contemplated by this Agreement, taking into account, among other things, the long term prospects and interests of SeaMED and its stockholders (any such superior Takeover Proposal being referred to in this Agreement as a "Superior Proposal"); or (iii) in the case referred to in clause (b) above, the SeaMED Board of Directors determines (after consultation with its financial adviser) that there is a reasonable likelihood that such Person has the financial and other resources to make a Superior Proposal. SeaMED agrees that it will take the necessary steps to promptly inform its Representatives of the obligations undertaken in this Section 3.9.3 and in the Confidentiality Agreement. SeaMED will promptly notify Plexus if any such inquiries, proposals or offers are received by, any such information is requested from, or any such discussions or negotiations are sought to be initiated or continued with, SeaMED or any of its Representatives relating to a Takeover Proposal, indicating, in connection with such notice, the name of such Person and the material terms and conditions of any proposals or offers and thereafter shall keep Plexus informed, on a current basis, on the status and terms of any such proposals or offers and the status of any such negotiations or discussions, except to the extent that the Board of Directors of SeaMED determines, based upon the written advice of outside legal counsel, that such action is inconsistent with its fiduciary duties under applicable Law. SeaMED also will promptly request each Person that has heretofore executed a confidentiality agreement in connection with its consideration of a Takeover Proposal to return all confidential information heretofore furnished to such Person by or on behalf of it or any of its subsidiaries. 3.9.4 Termination. SeaMED may, by notice to Plexus at any time prior to the Effective Time of Merger, whether before or after the approval by the SeaMED Shareholders, terminate this Agreement if SeaMED enters into, executes or agrees to a Superior Proposal following a good faith determination by the Board of Directors of SeaMED (after compliance by SeaMED with the provisions of Section 3.9.3 of this Agreement) based upon the written advice of outside legal counsel, that such action is necessary to fulfill its fiduciary duties under applicable Law; provided that SeaMED pays Plexus the Break-up Fee provided in Section 3.9.5 hereof. 3.9.5 Break-up Fee. SeaMED agrees to pay Plexus, (provided that Plexus is not then in material breach of any representation, warranty, covenant or agreement contained in this Agreement) within two (2) business days after the termination of this Agreement (or such later date as may apply in the case of (ii) below) by wire transfer, the sum of $3.2 Million in immediately available funds, plus interest on the amounts owed at the prime rate as announced by Key Bank N.A. in effect from time to time during such period plus two percent (the "BREAK-UP FEE") in the event that following the date of the execution of this Agreement, and at or prior to the termination of this Agreement, any of the following events shall have occurred: -17- 24 (i) Plexus shall have terminated this Agreement pursuant to Section 9.1(c)(v), (vi), (vii) or (viii) hereof; or (ii) if (A) either (y) SeaMED, any of its subsidiaries or any of their Representatives shall have taken any actions pursuant to clause (b) or (c) of the proviso set forth in Section 3.9.3 or (z) an Other Proposal shall have been made to SeaMED or its stockholders or any Person shall have publicly announced an intention (whether or not conditional) to make such an Other Proposal with respect to SeaMED and thereafter this Agreement is terminated by either Plexus or SeaMED pursuant to Section 9.1(c)(iv) or 9.1(d)(iii), respectively, and (B) SeaMED consummates an agreement for an Other Transaction within twelve (12) months after termination of this Agreement, SeaMED shall promptly, but in no event later than the date of such consummation, pay to Plexus the Break-up Fee. The right to the payment of the fees set forth in this Section 3.9.5 shall be the exclusive remedy at law or in equity to which Plexus may be entitled upon termination of this Agreement pursuant to Section 9.1(c)(v), (vi) or (vii) hereof. SeaMED acknowledges that the agreements contained in this Section 3.9.5 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Plexus and Acquisition would not enter into this Agreement. If SeaMED fails to promptly pay the amount due pursuant to this Section 3.9.5 and, in order to obtain such payment, Plexus commences a suit which results in a judgment against SeaMED for the fee set forth therein, if Plexus prevails in such suit, SeaMED shall pay to Plexus its reasonable costs and expenses (including attorneys' fees) in connection with such suit, together with interest from the date of termination of this Agreement. The agreements contained in this Section 3.9.5 of this Agreement are an integral part of this Agreement and constitute liquidated damages and not a penalty. 3.10 Letter of SeaMED's Accountants.

(a) Indemnification. From and after the Effective Time of Merger, Plexus shall indemnify and hold harmless, to the fullest extent permitted under applicable Law (and Plexus shall also advance expenses as incurred to the extent permitted under applicable Law, provided the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that said Person is not entitled to indemnification), each present and former employee, agent, director or officer of SeaMED and the heirs, successors and assigns of such Persons (the "Indemnified Parties") against any amounts incurred by such Indemnified Parties, including without limitation, losses, claims, damages, liabilities, costs, expenses (including reasonable attorneys fees incurred in defense or otherwise), judgments and amounts paid in settlement, in connection with any claim, action, suit, proceeding or investigation (i) arising out of or relating to the transactions described in this Agreement or (ii) which arise out of or relate to an Indemnified Party having served as a committee member, director, officer, employee or agent of SeaMED, or as a trustee or fiduciary of any Employee Benefit Plans or otherwise on behalf of SeaMED, whether asserted or commenced prior to or after the Effective Time of Merger. (b) Insurance. For at least three (3) years from and after the Effective Time of Merger, Plexus shall maintain, or shall cause to be maintained, in effect directors and officers insurance covering those Persons covered by SeaMED's directors and officers insurance as of the date of this Agreement. This directors and officers insurance shall be not less in terms of coverage and amount as the insurance that SeaMED has in effect covering such officers and directors on the date of this Agreement. (c) Notice; Procedure. Any Indemnified Party wishing to claim Indemnification under Section 3.14(a) of this Agreement, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Plexus thereof, but the failure to so notify shall not relieve Plexus of any liability it may have to such Indemnified Party if such failure does not materially prejudice Plexus. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time of Merger): (i) Plexus shall have the right to assume the defense thereof with counsel reasonably acceptable to the Indemnified Party and Plexus shall not be liable to any Indemnified Party for any legal expenses of other counsel thereafter incurred in connection with the defense thereof, unless the Indemnified Party shall have been advised by such counsel that there may be one or more legal -19- 26 defenses available to it that are different from or in addition to those available to the indemnifying party that reasonably may be expected to lead to conflicts in representation (in which case, if the Indemnified Party notifies the indemnifying party in writing that it elects separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such action on behalf of the Indemnified Party with respect to such defenses); (ii) the Indemnified Party will cooperate in all respects as reasonably requested by Plexus in the defense of any such matter, and in connection therewith shall be entitled to reimbursement by Plexus of expenses incurred in connection therewith; and (iii) Plexus shall not be liable for any settlement effected without its prior written consent, which consent shall not be unreasonably withheld or delayed; provided, however, that Plexus shall not have any obligation hereunder to any Indemnified Party if a court shall ultimately determine, and such determination shall have become final and nonappealable, that the indemnification of such Indemnified Party in the matter contemplated hereby is prohibited by Law. If such indemnity is not available with respect to any Indemnified Party, the Plexus and the Indemnified Party shall contribute to the amount payable in such proportion as is appropriate to reflect relative faults and benefits. (d) Indemnified Parties. The provisions of this Section 3.14 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties. Nothing in this Section 3.14 shall limit in any way any other rights to indemnification that any current or former director or officer of SeaMED may have by contract or otherwise. (e) Articles of Incorporation; Bylaws. From and after the Effective Time, SeaMED shall fulfill, assume and honor in all respects the obligations of SeaMED pursuant to SeaMED's Articles of Incorporation, bylaws, and any indemnification agreement between SeaMED and any of SeaMED's directors and officers existing and in force as of the date of this Agreement. SeaMED agrees that the indemnification obligations set forth in SeaMED's Articles of Incorporation and bylaws, in each case as of the date of this Agreement, shall survive the Merger with respect to any matter which is based in whole or in part on or arises in whole or in part out of the fact that an individual is or was a director or officer of SeaMED prior to the Effective Time of Merger. 3.15 Agreement of Plexus. From and after the date of this Agreement and until the Effective Time of Merger, Plexus shall, and shall cause the other Plexus Companies to, diligently carry on its business only in the regular course and in substantially the same manner as heretofore, provided that acquisitions by any of the Plexus Companies of business enterprises engaged in businesses consistent with the businesses of Plexus Companies shall be permitted under this Section 3.15 of this Agreement. 3.16 Operation of Subsidiary; Relocation of Facilities. Plexus acknowledges that it intends to operate SeaMED following the Merger as a separate profit center to design, engineer and manufacture medical and commercial products, provided that such operations of SeaMED must be consistent with Plexus's business plan to maximize the synergies with SeaMED and other Plexus Companies to expand the manufacturing of medical and commercial products by SeaMED and Plexus. Plexus acknowledges that it intends to continue to use SeaMED's name with Plexus's name on a blended basis for at least one (1) year after the Effective Time of Merger. Plexus acknowledges that it has no current plans to relocate SeaMED -20- 27 operations, and Plexus agrees that after the Effective Time of Merger, it will use its reasonable business efforts to cause SeaMED to maintain SeaMED's operations in the Seattle metropolitan area for a period of not less than three (3) years. The parties acknowledge the timing and location of possible relocations could be affected by lease terminations and/or opportunities. This section is not intended to confer upon any person, other than the parties to this Agreement, any rights or remedies hereunder. 3.17 Employee Benefits. Plexus agrees that SeaMED will, as the Surviving Corporation, provide benefits for SeaMED employees that are substantially equivalent to the benefits provided to similarly situated Plexus employees, with prior service considerations as if such SeaMED employees had been employed by Plexus for the period for which they were employed by SeaMED; provided, however, that nothing contained herein shall be considered as requiring Plexus or SeaMED to continue any specific plan or benefit or as precluding amendments to any specific plan or benefit; and provided further, that nothing expressed or implied in this Agreement shall confer upon any employee, beneficiary, dependent, legal representative or collective bargaining agent of such employee any right or remedy of any nature or kind whatsoever under or by reason of this Agreement, including without limitation any right to employment or to continued employment for any specified period, at any specified location or under any job category, or any specific benefits or specific employee benefit plan. 3.18 Severance Benefits. Plexus shall cause the following severance benefits to be provided to SeaMED employees whose employment is terminated by Plexus or SeaMED without Cause as a result of the Merger within one year after the Effective Time of Merger, as follows: except as otherwise provided in individual employment agreements, employees will receive on termination severance pay equal to one week base salary for each year of prior service with SeaMED plus one additional month base salary. For purposes of this Section 3.18, "Cause" shall mean termination resulting from a good faith determination by Plexus after reasonable investigation that there has been (x) a failure or refusal in a material respect to follow the reasonable policies and directives of Plexus, after being provided with written notice and a reasonable opportunity to cure; (y) a failure to perform in good faith the duties of his or her position after being provided with written notice and a reasonable opportunity to cure; (z) any act involving embezzlement, theft, material dishonesty, or a conviction of or plea of nolo contendere to a crime involving moral turpitude or a felony. 3.19 Combined Financial Results. Plexus covenants and agrees that, as promptly as practicable following the end of Plexus's fiscal year, it will publicly release the combined financial results of Plexus and the Plexus Companies (including SeaMED). 3.20 S-3 Registration. Prior to the end of Plexus's fiscal year, Plexus shall prepare and file with the SEC a registration statement on Form S-3 (or any successor or other appropriate form) for resale of shares of Plexus Common Stock issued in the Merger to R. Scott Asen, and shall use its best efforts to have such filing declared effective under the Securities Act as promptly as practicable thereafter and to continue the effectiveness of such registration until the first anniversary of the Effective Time of Merger. Plexus may postpone, for up to sixty (60) days, the filing of such a registration statement if such registration would give rise to a disclosure obligation that would not be in the best interest of Plexus's shareholders. If, after the registration -21- 28 statement becomes effective, the continuation of the registration statement would give rise to a disclosure obligation that would not be in the best interest of Plexus's shareholders or if Plexus considers it necessary for the registration statement to be amended, such shareholder shall suspend sales until Plexus advises him that such disclosure has been made or is no longer required, or the registration statement has been amended, as the case may be. Plexus shall promptly notify the shareholder of any event, and use its reasonable best efforts to minimize any such postponement or suspension. 3.21 Additional Board Actions. SeaMED's Board of Directors shall, on or before the Closing Date, take all such actions, conditioned upon the occurrence of the Closing, necessary to redeem all outstanding rights of any holders of SeaMED Rights and to suspend operation of the Employee Stock Purchase Plan, and, if necessary, to ensure approval of the Merger under appropriate sections of WBCA (including without limitation WBCA 23B.19.040).
