AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (the "Agreement") is made and entered into as of August 25, 2003, by and among McDATA Corporation, a Delaware corporation ("Parent"); Whitney Acquisition, Inc., a Delaware corporation and wholly-owned subsidiary of Parent ("Merger Sub"); and Sanera Systems, Inc., a Delaware corporation ("Company").

RECITALS

A. The Boards of Directors of Company, Merger Sub and Parent believe it is in the best interests of their respective corporations and the stockholders of their respective corporations to enter into a business combination by means of a statutory merger of Merger Sub with and into Company (the "Merger") and, in furtherance thereof, have approved this Agreement and the Merger.

B. Pursuant to the Merger, among other things, the outstanding shares of Series A Convertible Preferred Stock, par value $.0001 per share, of Company ("Series A Preferred"), the outstanding shares of Series B Convertible Preferred Stock, par value $.0001 per share, of Company ("Series B Preferred") and the outstanding shares of Series C Convertible Preferred Stock, par value $.0001 per share, of Company ("Series C Preferred, and, together with the Series A Preferred and Series B Preferred, the "Preferred Stock") and the outstanding shares of common stock, $.0001 par value per share, of Company (the "Common Stock") shall be converted into the right to receive cash from Parent on the terms and subject to the conditions set forth herein. The Company's right of repurchase with respect to all outstanding shares of Common Stock shall lapse automatically in connection with the Merger and vesting of options (the "Options") to purchase shares of Common Stock issued pursuant to Company's 2000 Stock Option/Stock Issuance Plan, as amended (the "Company Plan"), will accelerate and become fully exercisable prior to the effective time of the Merger. The Options will not be assumed by Parent or Merger Sub and will expire automatically in connection with the Merger. Certain outstanding warrants of Company to acquire shares of Common Stock will terminate automatically in connection with the Merger in accordance with their terms (the "Expiring Warrants"). Certain other outstanding warrants of Company to acquire shares of Common Stock and/or Preferred Stock will have an exercise price higher than the proceeds payable to the holder of the shares underlying such warrants and will remain as such for their entire terms (the "Other Warrants" and, together with the Expiring Warrants, the "Warrants").

C. Parent shall have the option to make an election under Section 338(g) of the Internal Revenue Code of 1986, as amended (the "Code"), with respect to the Merger.

D. Concurrently with the execution of this Agreement, each of the security holders of Company set forth on Exhibit A attached hereto is executing and delivering to Parent a Voting Agreement substantially in the form set forth in Exhibit A attached hereto (the "Voting Agreement").

NOW, THEREFORE, in consideration of the representations, warranties, covenants, agreements and mutual promises set forth herein, and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties agree as follows:

Company, 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 (the "Closing") shall take place as soon as practicable after the satisfaction or waiver of each of the conditions set forth in Article VI hereof or at such other time as the parties hereto mutually agree (the "Closing Date").

1.4 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement, the Delaware Certificate of Merger and the applicable provisions of Delaware Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the assets, property, rights, privileges, powers and franchises of Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation, and the Surviving Corporation shall be a wholly-owned subsidiary of Parent.

1.5 Certificate of Incorporation; Bylaws.

(a) Certificate of Incorporation. Unless otherwise determined by Parent prior to the Effective Time, at the Effective Time the Certificate of Incorporation of Merger Sub, as in effect immediately prior to the Effective Time, shall be the Certificate of Incorporation of the Surviving Corporation (except that the name of the Surviving Corporation shall be amended to become "Sanera Systems, Inc.") until thereafter amended, as provided by Delaware Law and such Certificate of Incorporation.

(b) Bylaws. Unless otherwise determined by Parent prior to the Effective Time, at 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 (except that the name of the Surviving Corporation shall be amended to become "Sanera Systems, Inc.") until thereafter amended, as provided by Delaware Law, the Surviving Corporation's Certificate of Incorporation and such Bylaws.

(c) Directors and Officers. From and after the Effective Time, the directors and officers of Merger Sub shall become the directors and officers of the Surviving Corporation (retaining their respective positions and terms of office), in each case until their respective successors are duly elected or appointed and qualified.

1.6 Merger Consideration.

(a) Conversion of Company Securities. At the Effective Time by virtue of the Merger:

(i) Without any action on the part of the holders of Preferred Stock or Common Stock, each share of Preferred Stock and Common Stock issued and outstanding immediately prior

to the Effective Time, and all rights and privileges in respect thereof, shall forthwith cease to exist and be converted into the right to receive:

(A) with respect to the shares of Series C Preferred and pro rata among all shares of Series C Preferred, an amount equal to $0.54 in cash (without interest) per share of Series C Preferred from Parent plus the amount set forth in subsection 1.6(a)(i)(D) below (the "Series C Payment");

(B) with respect to the shares of Series B Preferred and pro rata among all shares of Series B Preferred, an amount equal to $1.00 in cash (without interest) per share of Series B Preferred from Parent (the "Series B Payment");

(ii) Without any action on the part of the holders of the Options, the vesting of each Option issued and outstanding immediately prior to the Effective Time shall accelerate in full. To the extent any such Option has not been exercised prior to the Effective Time, each such Option, and all rights and privileges in respect thereof, shall forthwith cease to exist and shall automatically be terminated and the holder of each such Option immediately prior to such termination shall promptly after the Effective Time receive from the Surviving Corporation, for each share of Common Stock subject to each such terminated Option, an amount in cash equal to the excess, if any, of the Per Common Share Merger Consideration over the per share exercise price of such Option, without interest, in full settlement of the termination of the corresponding Option and, to the extent that the per share exercise price of any Option equals or exceeds the Per Common Share Merger Consideration, at the Effective Time such Option shall cease to exist and automatically be terminated and the holder thereof shall not receive or be entitled to receive any consideration in respect of such Option. The amounts payable pursuant to this Section 1.6(a)(ii) shall be subject to all applicable withholding taxes.

(iii) Without any action on the part of the holders of shares of Common Stock subject to repurchase by Company, the Company's repurchase rights shall lapse and such shares shall be fully vested and converted into the right to receive the amount set forth in Section 1.6(a)(i)(D) above.

(iv) Without any action on the part of the holders of the Expiring Warrants, each Expiring Warrant issued and outstanding immediately prior to the Effective Time, and all rights and privileges in respect thereof, shall forthwith cease to exist and terminate without consideration.

(v) Except pursuant to the terms of Sections 1.11, 8.3(b) and 8.5, in no event shall Parent be required to make cash payments exceeding the Merger Consideration pursuant to the terms of this Agreement. Except pursuant to the terms of Section 1.11, in no event shall Parent be required to issue any share of stock or securities or options, warrants or other securities exercisable for or convertible into shares of Parent stock or securities pursuant to the terms of this Agreement. An aggregate of $13,558,804 of the Merger Consideration (as

defined below) shall be subject to escrow pursuant to Sections 1.8(b) and 8.2 and as set forth in the Escrow Agreement.

(vi) "Merger Consideration" shall mean an amount equal to $110,588,039.91 (a) plus the amount of proceeds received by Company in exchange for shares of its Series C Preferred issued on or after August 1, 2003 and prior to the Closing Date, (b) plus the amount of proceeds received or receivable by the Company on or after August 1, 2003 and prior to the Closing Date pursuant to the exercise of the Options and the Warrants held by holders who are not employees of Company (assuming full exercise of all such outstanding Options and in-the-money Warrants held by such holders), (c) plus any amounts set forth on Schedule 1.6(a)(vi)(c) of the Company Disclosure Schedule, (d) minus the amount of fees, costs and expenses of attorneys, accountants, consultants, investment bankers, brokers and finders actually incurred by the Company on or prior to the Closing Date, and (e) minus any payments made by the Company prior to the Closing Date to third parties that are outside of the Ordinary Course of Business of Company and are not agreed to by Parent; provided that the parties hereby agree and acknowledge that (i) any payments made to Venture Lending & Leasing III, Inc. or its affiliates or assignees (collectively, "VLL") in connection with the payment in full of the Company's debt and other obligations to such entity shall be deemed to be within the Company's Ordinary Course of Business and (ii) any payments set forth on Schedule 1.6(a)(vi)(e) of the Company Disclosure Schedule shall be deemed to be outside of the Company's Ordinary Course of Business for purposes of this Section 1.6(a)(vi). In addition to the foregoing, (x) if the sum of the Company's aggregate cash, cash equivalents and investments (including any restricted cash and any deposits with other institutions pursuant to leases or other agreements) as of September 30, 2003 (1) is less than $9,785,000, then the Merger Consideration shall be decreased by the difference between $9,785,000 and such aggregate cash, cash equivalents and investments balance or (2) is more than $10,815,000, then the Merger Consideration shall be increased by the difference between such aggregate cash balance and $10,815,000, and (y) if the aggregate amount of current liabilities to be assumed by Parent pursuant to the terms hereof (other than the deferred revenue related to the payments made pursuant to the OEM Agreement between the Company and Computer Network Technology Corporation dated as of December 3, 2002 and deferred rent) (the "Assumed Indebtedness") as of September 30, 2003 (assuming that the Company agreement with VLL has not been terminated or amended and the Company indebtedness thereunder remains outstanding) (1) exceeds $3,302,250, then the Merger Consideration shall be decreased by the difference between the amount of such Assumed Indebtedness and $3,302,250, or (2) is less than $2,987,750, then the Merger Consideration shall be increased by the difference between $2,987,750 and the amount of such Assumed Indebtedness. All amounts set forth in the preceding sentence shall be determined prior to giving effect to any loans made by Parent to Company and any amounts received or paid by Company described in clauses (a) through (e) of this subsection 1.6(a)(vi).

(b) Cancellation of Capital Stock Owned by Company. At the Effective Time, all shares of capital stock of Company that are held in the treasury of Company or owned by Company immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof and without payment of any consideration therefor.

(c) Conversion of Merger Sub Common Stock. At the Effective Time, each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall remain outstanding and shall represent one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation.

1.7 Dissenting Shares.

(a) Dissenter's Rights. Notwithstanding any provision of this Agreement to the contrary, any capital stock of Company held by a holder who has exercised such holder's dissenter's rights in accordance with Section 262 of Delaware Law or in accordance with Chapter 13 of the California General Corporation Law (the "California Code") ("Dissenting Shares"), and who, as of the Effective Time, has not effectively withdrawn or lost such dissenter's rights (a "Dissenting Stockholder"), shall not be converted into or represent a right to receive the Merger Consideration, if applicable, pursuant to Section 1.6, and the Dissenting Stockholder shall be entitled only to such rights as are granted by Section 262 of Delaware Law or Chapter 13 of the California Code.

(b) Loss of Dissenter's Rights. Notwithstanding the provisions of Section 1.7(a), if any Dissenting Stockholder shall effectively withdraw or lose (through failure to perfect or otherwise) his rights to receive payment for the fair market value of his Dissenting Shares under Delaware Law or the California Code, then, as of the later of the Effective Time or the occurrence of such event, such Dissenting Stockholder's capital stock of Company shall automatically be converted into and represent only the right to receive his pro rata portion of the Merger Consideration, if applicable, without interest, upon surrender of the Company Certificates (as defined in Section 1.8(a)) representing such shares to Parent pursuant to Section 1.8.

(c) Notice. Company shall (i) comply with the requirements of Section 262 of Delaware Law and Chapter 13 of the California Code, (ii) give Parent prompt notice of any written demands for payment with respect to capital stock of Company pursuant to Section 262 of Delaware Law and Chapter 13 of the California Code, withdrawals of such demands, and copies of any documents or instruments served pursuant to Delaware Law and the California Code and received by Company, and (iii) give Parent the opportunity to participate in all negotiations and proceedings with respect to demands for dissenter's rights under Delaware Law or the California Code. Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to any demands for dissenter's rights with respect to any Dissenting Shares or offer to settle or settle any such demands.

1.8 Surrender of Certificates.

(a) Payment Procedures.

(i) From and after the Effective Time, all shares of capital stock of Company shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented outstanding shares of Company capital stock (the "Company Certificates") shall cease to have any rights with respect thereto, except for the right, upon surrender to Parent of Company Certificates for cancellation, to receive in exchange therefor the Merger Consideration set forth in Section 1.6, and the Company Certificate so surrendered shall forthwith be canceled. Until so surrendered, each outstanding Company Certificate will be deemed from and after the Effective Time, for all corporate purposes, to evidence only the right to receive the Merger Consideration.

(ii) As soon as reasonably practicable after the Effective Time, Parent shall mail to each Company stockholder of record (A) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Company Certificates shall pass, only upon delivery of the Company Certificates to Parent and shall be in such form and have such other provisions as Parent and Company may mutually specify) and (B) instructions for effecting the

surrender of the Company Certificates in exchange for the Merger Consideration. Upon surrender of a Company Certificate by a Company stockholder for cancellation to Parent or to such other agent or agents as may be appointed by Parent, together with delivery of a duly executed letter of transmittal, Parent shall pay and deliver to each such Company stockholder the Merger Consideration in exchange therefor. No interest will accrue or be paid to any holders of Company Certificates.

(b) Escrow. Subject to and in accordance with the provisions of Article VIII and the Escrow Agreement (as defined in Section 6.1(c)) and subject to the surrender to Parent of all Company Certificates held by the Company stockholders, at the Effective Time, Parent shall cause to be distributed to the Escrow Agent (as defined in Section 8.2) $13,558,804 of the Merger Consideration payable to the holders of Preferred Stock and Common Stock pursuant to Section 1.6(a)(i) as set forth on Exhibit C attached hereto (the "Escrow Fund"). The Escrow Fund shall be held in escrow and shall be available to compensate Parent on an exclusive basis for damages as provided in Article VIII and the Escrow Agreement. To the extent not used to compensate Parent for such damages, the Escrow Fund shall be released to the Company stockholders as provided in Article VIII and the Escrow Agreement.

(c) Options. From and after the Effective Time, all Options shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of an Option shall cease to have any rights with respect thereto.

(d) Expiring Warrants. From and after the Effective Time, all Expiring Warrants shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of an Expiring Warrant shall cease to have any rights with respect thereto.

(e) Other Warrants. From and after the Effective Time, all Other Warrants shall remain outstanding.

1.9 Lost, Stolen or Destroyed Certificates. In the event any Company Certificates shall have been lost, stolen or destroyed, Parent shall issue in exchange for such lost, stolen or destroyed Company Certificates, upon the making of an affidavit of that fact by the holder thereof that portion of the Merger Consideration payable to such holder pursuant to Section 1.6 in exchange for the shares of capital stock held by such holder; provided, however, that as a condition precedent to the payment thereof, such holder shall deliver to Parent such affidavit agreeing to indemnify and hold harmless Parent from and against any claim that may be made against Parent, the Surviving Corporation, Company or any of their respective directors, officers, employees, affiliates or agents with respect to the Company Certificates alleged to have been lost, stolen or destroyed.

1.10 Closing of Company's Transfer Books. At and after the Effective Time, holders of capital stock of Company shall cease to have any rights as stockholders of Company, except for the right to the Merger Consideration. At the Effective Time, the stock transfer books of Company shall be closed and no transfer of shares of capital stock of Company and any other securities of Company, including, but not limited to, any options and warrants, which were outstanding immediately prior to the Effective Time shall thereafter be made.

1.11 Employee Consideration.

(a) Subject to subsections 1.11(d) and (e) below, within three business days following the Effective Time, Parent shall pay to the employees of Company listed on Exhibit D attached hereto (each an "Employee" and collectively, the "Employees") the amount in cash in the aggregate set forth on Exhibit D (to each Employee the amount set forth opposite his or her name on such Exhibit under the Employee Cash Consideration column), subject to adjustment as set forth in subsection 1.11(c) below (the "Employee Cash Consideration").

(b) Subject to subsections 1.11(d) and (e) below, within three business days following the Effective Time, Parent shall issue to the Employees a number of shares of Class B Common Stock of Parent equal to the amount in cash in the aggregate set forth on Exhibit D (to each Employee the amount set forth opposite his or her name on such Exhibit under the Employee Stock Consideration column), subject to adjustment as set forth in subsection 1.11(c) below, divided by the average of the regular trading day closing price per share of Parent's Class B Common Stock, as reported on the Nasdaq National Market, for the five (5) trading days ending on and including the business day immediately prior to the public announcement of the transactions contemplated by this Agreement and the five (5) trading days ending on and including the business day immediately prior to the Effective Time (the "Employee Stock Consideration").

(c) The amount of Employee Cash Consideration and Employee Stock Consideration set forth on Exhibit D shall be increased by an amount equal to (i) with respect to the Employee Cash Consideration, 25% of any proceeds received or receivable by Company after August 1, 2003 and prior to the Closing Date pursuant to the exercise of the Options and the Warrants held by holders who are employees of Company (assuming full exercise of all such outstanding Options and in-the-money Warrants held by such holders) and (ii) with respect to the Employee Stock Consideration, 75% of such proceeds, so that the aggregate amount of Employee Cash Consideration and Employee Stock Consideration is increased on a dollar-for-dollar basis for any such proceeds received by Company.

(i) with respect to twenty-five percent (25%) of the Employee's Employee Cash Consideration and twenty-five percent (25%) of the Employee's Employee Stock Consideration, at the one-year anniversary of the Closing Date, provided, however, that, subject to subsection 1.11(f) below, a payment to the Employee of such 25% portion of the Employee Cash Consideration shall be made, and the 25% portion of the Employee's Employee Stock Consideration shall vest, only if such Employee has been providing continuous services to the Surviving Corporation, Parent or any of their respective affiliates from the Closing Date through the one-year anniversary of the Closing Date; and

(ii) with respect to the remaining fifty percent (50%) of the Employee's Employee Cash Consideration and the remaining fifty percent (50%) of the Employee's Employee Stock Consideration, (x) if any of the Payment Milestones (as defined below) have been timely achieved by the dates set forth opposite such Payment Milestones on Exhibit H hereto, then with respect to that percentage applicable to each such timely achieved Payment Milestone as indicated on Exhibit H, in a series of six (6) equal monthly installments beginning at the end of the first month following the one-year anniversary of the Closing Date, or (y) if any of the Payment Milestones have not been timely achieved by the dates set forth opposite such Payment Milestones on Exhibit H hereto, then with respect to that percentage applicable to

each such Payment Milestone which has not been timely achieved as indicated on Exhibit H, in a series of twelve (12) equal monthly installments beginning at the end of the first month following the one-year anniversary of the Closing Date; provided, however, that, subject to subsection 1.11(f) below, payment to the Employee of such 50% of the Employee's Employee Cash Consideration shall be made, and the 50% portion of the Employee's Employee Stock Consideration shall vest, only if such Employee has been providing continuous services to the Surviving Corporation, Parent or any of their respective affiliates from the Closing Date through the applicable date of such payment or lapse.

(iii) The conditions upon payment of the Employee Cash Consideration and upon the issuance of the Employee Stock Consideration set forth in subsections 1.11(e)(i) and (ii) above shall be the only conditions to such payment and issuance, and neither the Employee Cash Consideration nor the Employee Stock Consideration shall be subject to the escrow or indemnification provisions set forth in Article VIII hereof or the Escrow Agreement.

(f) Notwithstanding the above, with respect to any Employee, the payment of the Employee Cash Consideration and the vesting with respect to the Employee Stock Consideration (i) shall be subject to the acceleration provisions set forth in the Acceleration Agreements (as defined in Section 6.2(f) hereof) with respect to the Employees who are a party thereto and (ii) may be accelerated or otherwise modified by a written agreement between Parent and any such Employee, it being agreed that Parent will review such arrangements on a case-by-case basis.

(a) Confidential Information. Prior to the Effective Time, each of the parties will treat and hold as such all of the Confidential Information (as defined below) and refrain from using any of the Confidential Information except in connection with the transactions contemplated by this Agreement. In the event that any party is requested or required (by oral question or request for information or documents in any legal proceeding, interrogatory, subpoena, civil investigative demand, or similar process) to disclose any Confidential Information, that party will notify the party providing such Confidential Information (the "Providing Party") promptly of the request or requirement so that the Providing Party may seek an appropriate protective order or waive compliance with the provisions of this Section 5.2(a). If, in the absence of a protective order or the receipt of a waiver hereunder, any of the parties is, on the advice of counsel, compelled to disclose any Confidential Information to any tribunal or else stand liable for contempt, that party may disclose the Confidential Information to the tribunal; provided, however, that the disclosing party shall use its commercially reasonable best efforts to obtain, at the request and expense of the Providing Party, an order or other assurance that confidential treatment will be accorded to such portion of the Confidential Information required to be disclosed as the Providing Party shall designate. For purposes of this Agreement, "Confidential Information" means any information concerning the business and affairs of Parent, Merger Sub, Company or any of Parent's subsidiaries that is not already generally available to the public. Notwithstanding anything herein to the contrary and except as reasonably necessary to comply with any applicable federal and state securities laws, the receiving party or its Representatives may disclose to any and all persons without limitation of any kind, the U.S. federal and state tax treatment and tax structure of the transaction and all materials of any kind (including opinions or other tax analyses) that are provided to the receiving party relating to such U.S. federal or state tax treatment and tax structure. For this purpose, "tax structure" is any fact that may be relevant to understanding the U.S. federal or state tax treatment of the transaction. However, the foregoing shall not be construed to permit disclosure by the receiving party or its Representatives of any information of a technical nature concerning research and development and engineering activity disclosed by the disclosing party, including without limitation, software or firmware code, semiconductor or printed circuit board layout diagrams, product designs or specifications, manufacturing know-how and patent applications.

(b) Termination. In the event that this Agreement is terminated in accordance with its terms, each party shall promptly redeliver to the other all written or other tangible Confidential Information and shall not retain any copies, extracts or other reproductions in whole or in part of such written material. In such event, all documents, memoranda, notes and other writings prepared by Parent, Merger Sub, Company or any of Parent's subsidiaries based on the information in such material shall be destroyed (and Parent, Merger Sub and Company shall use their respective reasonable best efforts to cause their Representatives to similarly destroy their documents, memoranda and notes), and such destruction (and reasonable best efforts) shall be certified in writing by an authorized officer supervising such destruction.

(c) Remedy. Company, Parent and Merger Sub (i) acknowledge that a breach of any of the covenants contained in this Section 5.2(c) will result in irreparable harm to the other parties which will not be compensable in money damages, and (ii) agree that such covenants shall be specifically enforceable and that specific performance and injunctive relief shall be a remedy properly available to the other parties for a breach of such covenants.

5.3 Public Disclosure. Unless otherwise permitted by this Agreement, Parent and Company shall consult with each other before issuing any release or otherwise making any public statement or making any other public (or non-confidential) announcement or disclosure (whether or not in response to an inquiry) regarding the terms of this Agreement and the transactions contemplated hereby, and neither shall issue any such press release or make any such statement or disclosure without the prior approval of the other (which approval shall not be unreasonably withheld); provided, however, that any party may make any public disclosure it believes in good faith is required by applicable law or any listing or trading agreement concerning its publicly-traded securities (in which case the disclosing party will use its reasonable best efforts to advise the other party prior to making the disclosure), and provided further that Company may make such disclosures to its securityholders as are necessary in connection with its solicitation of stockholder consent to the transactions contemplated hereby, in connection with the Company's current Series C Preferred financing and as are necessary or appropriate in the Information Statement (as defined in Section 5.11 hereof).

5.4 Reasonable Efforts and Further Assurances.

(a) Further Assurances. Each of the parties to this Agreement shall use its commercially reasonable best efforts to effectuate the transactions contemplated hereby and to fulfill and cause to be fulfilled the conditions to Closing under this Agreement; provided, however, that Parent shall not be obligated to consent to or accept any divestiture or operational limitation in connection with the Merger and neither party shall be obligated to make any payment or commercial concession to any third party as a condition to obtaining any required consent or approval of any third party, except as contemplated herein. Each party hereto, at the reasonable request of another party hereto, shall execute and deliver such other instruments and do and perform such other acts and things as may be necessary or desirable for effecting completely the consummation of this Agreement and the transactions contemplated hereby.

(b) Reasonable Efforts. Subject to the terms and conditions herein provided, each of the parties hereto shall use its commercially reasonable best efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable pursuant to all agreements, contracts, indentures, insurance policies, or other instruments to which the parties hereto are a party, or under any applicable laws and regulations, to consummate and make effective the transactions contemplated by this Agreement, including using its commercially reasonable best efforts to (i) obtain all necessary or appropriate waivers, consents and approvals from lenders, landlords, security holders or other parties whose waiver, consent or approval is required to consummate the Merger; provided, however, that Company shall not enter into any consent agreement that materially alters the terms of the related agreement in a manner adverse to the Company or will cause Company to have any obligations other than those set forth in the related agreement, without the prior written consent of Parent, (ii) effect all necessary registrations, filings and submissions, including, without limitation, the Form S-8, and (iii) lift any injunction or other legal bar to the Merger (and, in such case, to proceed with the Merger as expeditiously as possible), subject, however, to the requisite votes of the stockholders of Company.

In no event will Company submit any paper to, or take any action before, the United States Patent or Trademark Office without first receiving Parent's prior written approval, which approval will not be unreasonably withheld.

5.5 Notification of Certain Matters. Each of Company, Parent and Merger Sub agrees to give prompt notice to each other of, and to use their respective commercially reasonable best efforts to prevent or promptly remedy, (i) the occurrence or failure to occur or the impending or threatened occurrence or failure to occur, of any event which occurrence or failure to occur would be likely to cause any of the representations or warranties in this Agreement to be untrue or inaccurate in any material respect at any time from the date hereof to the Effective Time (as it may be modified in accordance with Article II hereof), and (ii) any failure on its part to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 5.5 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice.

5.6 Company Disclosure Schedule. Company has made, or will make, available to Parent, upon Parent's written request, within a reasonable time prior to the Closing Date, copies of all items set forth on the Company Disclosure Schedule and any and all other consents, documents or agreements to be delivered hereunder which have not previously been delivered to Parent, which items and any such other consents, documents or agreements shall be in form and substance reasonably satisfactory to Parent.

5.7 Litigation Support. In the event any litigation is commenced by any person or entity against Company relating to the transactions contemplated by this Agreement, Parent shall have the right, at its own expense, to participate therein, and Company will not settle any such litigation without the consent of Parent, which consent shall not be unreasonably withheld. In the event and for so long as Parent or Merger Sub actively is contesting or defending against any action, suit, proceeding, arbitration, hearing, investigation, charge, complaint, claim or demand (other than by security holders of Company) in connection with (a) any transaction contemplated under this Agreement, or (b) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act or transaction on or prior to the Closing involving Company, Company will cooperate with Parent and its counsel in the contest or defense, use reasonable efforts to make available the personnel of Company and provide such testimony and access to its books and records as shall be reasonably necessary in connection with the contest or defense, all at the sole cost and expense of Parent (unless Parent is entitled to indemnification therefor under Article VIII).

5.8 Transition. Company shall use its commercially reasonable best efforts to keep its business and properties substantially intact, including its present operations, physical facilities, working conditions and relationships with lessors, licensors, licensees, customers, suppliers, consultants, employees and other business associates of Company, except as otherwise contemplated by this Agreement or in the Company Disclosure Schedule (as it may be modified in accordance with Article II hereof). Company shall not take any action that is designed or intended to have the effect of discouraging any lessor, licensor, licensee, customer, supplier, consultant, employee or other business associate of Company from maintaining the same business relationships with Company after the Closing as it maintained with Company prior to the Closing, except as otherwise contemplated by this

Agreement or in the Company Disclosure Schedule (as it may be modified in accordance with Article II hereof).

If the Company calls such a meeting, Company shall use its commercially reasonable efforts to solicit from its stockholders proxies in favor of the Agreement and the Merger and, in any event, shall use commercially reasonable efforts to obtain a sufficient vote in favor of such matters. At the special meeting of Company stockholders or included in the written consent of the Company stockholders, the Company stockholders shall approve and appoint a Shareholder Representative (as defined in the Escrow Agreement) with full power and authority to represent and take binding actions on behalf of the Company stockholders and their successors and assigns with respect to all matters arising under the Escrow Agreement, including, without limitation, the negotiation and settlement of any disputes under the Escrow Agreement.

The Information Statement shall include the recommendation of the Board of Directors of Company that the stockholders of the Company vote their shares in favor of this Agreement and the Merger and such recommendation shall not be withdrawn or modified in a manner adverse to Parent.

5.12 Employees. The Employees set forth on Schedule 5.12 hereto (the "Selected Employees") shall be offered full-time at-will employment by Parent with the Surviving Corporation or Parent pursuant to an offer letter substantially in the form attached hereto as Exhibit L, to be effective as of the Closing Date and subject to such employee's execution and delivery to Parent of Parent's employee agreement (Employees delivering a Parent employee agreement are referred to herein as the "Continuing Employees"). Such offers of employment will provide for compensation and other benefits from Parent as may be determined by Parent in its sole discretion. This Section 5.12 shall not be deemed to limit the Parent's, Surviving Corporation's or Company's right to terminate any Selected Employees at any time, except as may otherwise be provided in the Acceleration Agreements.

5.13 Service Credit. Parent shall cause all of the Continuing Employees to be eligible for and to participate in such employer-funded employee compensation and benefit plans, programs, policies and arrangements that are made available by Parent and its subsidiaries to their own employees who are similarly situated (the "Parent Benefit Plans"), except that Parent may, at its discretion, elect to retain some or all of the Company's existing welfare benefit plans indefinitely in lieu of causing the Employees to be eligible to participate in the equivalent Parent Benefit Plan.

Eligibility for the Parent's 401(k) Profit Sharing Plan and Employee Stock Purchase Plan shall be effective as of the first open enrollment occurring on or after the Effective Time. From and after the Effective Time, Parent shall cause all of the Parent Benefit Plans to provide that all service of the Continuing Employees, as defined and recognized under Parent's benefits plans and consistent with applicable human resources policies, completed prior to the Closing with Company and its predecessors and affiliates will be recognized under the Parent vacation, time off and service award programs as if it were service with Parent for purposes of eligibility to participate in Parent Benefit Plans and vesting of benefits thereunder, provided that recognition of such service does not result in duplicate benefits. Each Continuing Employee is intended to be a third party beneficiary of this Section 5.13 and may specifically enforce its terms at or after the Effective Time.

5.14 Indemnification and Directors' and Officers' Insurance.

(a) After the Effective Time, the Surviving Corporation and Parent shall indemnify and hold harmless (and shall also advance expenses as incurred to the fullest extent permitted under applicable law to), to the extent not covered by insurance, each person who is now or has been prior to the date hereof or who becomes prior to the Effective Time an officer or director of the Company (the "Company Principals") against (i) all losses, claims, damages, costs, expenses (including reasonable counsel fees and expenses) settlement, payments or liabilities arising out of or in connection with any claim, demand, action, suit, proceeding or investigation based in whole or in part on or arising in whole or in part out of the fact that such person is or was an officer or director of the Company or any of its subsidiaries, whether or not pertaining to any matter existing or occurring at or prior to the Effective Time and whether or not asserted or claimed prior to or at or after the Effective Time ("Indemnified Liabilities"); and (ii) all Indemnified Liabilities based in whole or in part on or arising in whole or in part out of or pertaining to this Agreement or the transactions contemplated hereby, in each case to the fullest extent required or permitted under applicable law or agreement. Nothing contained herein shall make Parent, Merger Sub, Company or the Surviving Corporation, an insurer, a co-insurer or an excess insurer in respect of any insurance policies which may provide coverage for Indemnified Liabilities, nor shall this Section 5.14 relieve the obligations of any insurer in respect thereto. The parties hereto intend, to the extent not prohibited by applicable law, that the indemnification provided for in this Section 5.14 shall apply without limitation to negligent acts or omissions by a Company Principal. Each Company Principal is intended to be a third party beneficiary of this Section 5.14 and may specifically enforce its terms. Nothing in this Section 5.14 shall limit or otherwise adversely affect any rights any Company Principal may have under any agreement with Company or under Company's Certificate of Incorporation or bylaws as presently in effect.

(b) From and after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, fulfill and honor in all respects the obligations of Company pursuant to any indemnification agreements between the Company and its directors and officers as of or prior to the date hereof and any indemnification provisions under Company's Certificate of Incorporation or bylaws and shall not terminate any directors and officers liability insurance policy, each in effect

on the date hereof, for a period of six (6) years after the Effective Time; provided that the aggregate premium payable by Parent to continue such policy does not exceed $75,000.

(c) The provisions of this Section 5.14 are intended to be for the benefit of, and will be enforceable by, each person entitled to indemnification hereunder and the heirs and representatives of such person. Parent will not permit the Surviving Corporation to merge or consolidate with any other person unless the Company will ensure that the surviving or resulting entity assumes the obligations imposed by this Section 5.14. Notwithstanding anything herein to the contrary, the provisions of this Section 5.14 may not be amended as to any Company Principal without such Company Principal's prior written consent.

5.15 Form S-8 Registration Statement. Parent will use its reasonable efforts to file, no later than ten (10) days following the Closing Date, a registration statement on Form S-8 (or any successor to Form S-8) (the "Form S-8") so as to register the shares of Parent Common Stock subject to the Employee Stock Consideration and shall use its commercially reasonable best efforts to effect such registration and to maintain the effectiveness of such registration statement (and the current status of the prospectus contained therein).

8.1 Survival of Representations and Warranties. All of the representations and warranties of Parent, Merger Sub and Company contained in this Agreement shall survive the Closing and continue in full force and effect for a period of twelve (12) months following the Closing Date. All covenants and agreements of Parent, Merger Sub and Company contained in this Agreement shall survive the Closing and continue in full force for the periods specifically set forth therein or, if not so stated, for a period of twelve (12) months following the Closing Date.

8.2 Escrow Fund. In accordance with Sections 1.6(a) and 1.8(b) hereof, Parent shall deliver to ▇▇▇▇▇ Fargo Bank Minnesota, National Association, as escrow agent (the "Escrow Agent"), an aggregate of $13,558,804 of the Merger Consideration payable to the Company stockholders. The Escrow Fund shall be held by the Escrow Agent in an interest-bearing account pursuant to the terms set forth in the Escrow Agreement. The Escrow Fund shall be available to compensate Parent, the Surviving Corporation and the other Indemnified Persons (as defined in Section 8.6) pursuant to the indemnification obligations of the Company stockholders in accordance with this Article VIII and the Escrow Agreement. Notwithstanding any other provision of this Agreement or the Escrow Agreement, except as expressly provided in Section 8.3(b), subsequent to the Closing, the Escrow Fund shall be the sole and exclusive remedy of the Parent Indemnified Persons (as defined below) for any of their Damages caused by a breach of any representation, warranty, agreement or covenant in this Agreement or as set forth in the Escrow Agreement.

8.3 Limitations on Indemnification.

(a) Minimum Claim. Parent or the Surviving Corporation on the one hand and Company (prior to the Effective Time) or the Company Indemnified Persons (subsequent to the Effective Time) on the other hand shall not be entitled to make a claim for indemnification pursuant to Sections 8.4 or 8.5, respectively, unless and until the aggregate amount of Damages (as defined in Section 8.4(a)) incurred by the party making such claim exceeds $250,000 (the "Basket", provided that such Basket shall be $100,000 for any claims described in Section 8.4(b) only), at which time the party seeking indemnification may recover the aggregate amount of Damages beginning with the first dollar thereof irrespective of the Basket; provided, however, that the Basket shall not apply to Damages arising from the Cap Carve Outs (as defined in Section 8.3(b)), the failure to pay the Merger Consideration or the Employee Consideration, or as otherwise provided in Schedule A1(ii) of the Escrow Agreement.

(b) Cap. Notwithstanding any other provision of this Agreement or the Escrow Agreement, except for the payment of the Merger Consideration and the Employee Consideration, the indemnification obligations of Company (prior to the Effective Time) and the Company stockholders (subsequent to the Effective Time) on the one hand and Parent and the Surviving Corporation (after the Effective Time) on the other hand pursuant to Sections 8.4 and 8.5, respectively, will not exceed in the aggregate for such person or persons $13,558,804 (the "Cap"); provided, however, that Damages arising out of claims (i) due to fraud or intentional misrepresentation or (ii) resulting from a breach of any covenant or agreement of Company in Section 9.1 (collectively, the "Cap Carve Outs"), shall not apply towards the Cap. Notwithstanding the foregoing, (x) all claims by Indemnified Persons for Damages pursuant to Section 8.4 subsequent to the Closing shall be satisfied only from the Escrow Fund and shall be limited to the Cap, and any Damages arising out of claims from the Cap Carve Outs shall be satisfied first out of the Escrow Fund, if any, and (y) all claims by Indemnified Persons for Damages pursuant to Section 8.5 shall be limited to the Cap, other than in connection with any claims or Damages incurred in connection with Parent's failure to pay the Merger Consideration or the Employee Consideration pursuant to the terms hereof.

8.4 Indemnification by Company and Stockholders. Subject to the terms and conditions set forth in Section 8.3, Company (prior to the Effective Time) or each of the Company stockholders (subsequent to the Effective Time) from and to the extent of such stockholder's pro rata portion of the Escrow Fund, shall indemnify Parent, the Surviving Corporation and their respective directors, officers, employees, agents or advisors, or any of their respective successors and assigns (the "Parent Indemnified Persons"), in respect of, and hold each of them harmless against, any and all demands, claims, debts, actions, assessments, judgments, settlements, sanctions, obligations and other liabilities (whether absolute, accrued, contingent, fixed or otherwise, known or unknown, due or to become due or otherwise), monetary damages, fines, taxes, fees, penalties, interest obligations, deficiencies, losses, costs

and expenses (including, without limitation, amounts paid in settlement, interest, court costs, costs of investigators, reasonable fees and expenses of attorneys, accountants, financial advisors and other experts, and other expenses of litigation as incurred) ("Damages", provided, however, that Damages shall not include any consequential, speculative or punitive damages incurred by an Indemnified Person), incurred or suffered by them (a) resulting from, relating to, arising out of or constituting any breach of any Company representation or warranty (as modified by the Company Disclosure Schedule, as it may be modified in accordance with Article II hereof) or failure to perform any covenant or agreement of Company or a stockholder of Company contained in this Agreement or in any closing certificate delivered to Parent in connection with the Closing, (b) resulting from any amounts paid to Dissenting Stockholders for Dissenting Shares pursuant to Section 262 of Delaware Law or Chapter 13 of the California Code in excess of the value such Dissenting Stockholder would have received in the Merger for such Dissenting Shares and all reasonable costs, expenses and fees as directly incurred by Company, Parent or the Surviving Corporation in connection with the exercise of a Dissenting Stockholder's right under Section 262 of Delaware Law or Chapter 13 of the California Code, or (c) as otherwise provided in Schedule A1(ii) of the Escrow Agreement (in each of Section 8.4(a), (b) and (c), including any Damages suffered through and after the applicable survival period; provided, that such Damages result from events occurring prior to such time and provided further that Parent makes a written claim for indemnification against Company (prior to the Effective Time) or the Stockholder Representative (as defined in the Escrow Agreement) (subsequent to the Effective Time) pursuant to this Section 8.4 and Section 9.2 within the survival period set forth in Section 8.1, or as otherwise provided in Schedule A1(ii) of the Escrow Agreement, as the case may be.

8.5 Indemnification by Parent and Surviving Corporation. Subject to the terms and conditions set forth in Section 8.3, Parent and the Surviving Corporation, jointly and severally, shall indemnify Company and its stockholders and their respective directors, officers, employees, members, affiliates, partners, agents or advisors, or any of their respective successors and assigns (the "Company Indemnified Persons"), and hold them harmless against any and all Damages incurred or suffered by them resulting from, relating to, arising out of or constituting any breach of any representation or warranty of Parent or Merger Sub or any failure to perform any covenant or agreement of Parent or Merger Sub contained in this Agreement or in any closing certificate delivered hereby (including any Damages suffered through and after the applicable survival period); provided, that such Damages result from events occurring prior to such time and provided further that Company makes a written claim for indemnification against Parent pursuant to this Section 8.5 and Section 9.2 within the survival period set forth in Section 8.1.

8.6 Third Party Claims. Any party entitled to make a claim (or any of their affiliated parties (each an "Indemnified Person")) pursuant to this Article VIII shall give prompt written notification to the party obligated to provide such indemnification (the "Indemnifying Person") of the commencement of any action, suit or proceeding relating to a third party claim for which indemnification pursuant to this Article VIII may be sought (a "Third Party Claim"); provided, however, that no delay on the part of the Indemnified Person in notifying the Indemnifying Person shall relieve the Indemnifying Person from any liability or obligation under this Article VIII unless such notification delay shall prejudice the Indemnifying Person. Within 30 days after delivery of such notification, the Indemnifying Person may, upon written notice thereof to the Indemnified Person, assume control of the defense of such action, suit or proceeding with counsel reasonably satisfactory to the Indemnified Person, if (i) the Indemnifying Person provides the Indemnified Person with evidence reasonably acceptable to the Indemnified Person that the Indemnifying Person will have the financial resources to defend against the Third Party Claim and fulfill its indemnification obligations hereunder, (ii) the Third Party Claim involves only money damages and does not seek injunction or other equitable relief, and (iii) the Indemnifying Person conducts the defense of the Third Party Claim actively and diligently (and the Indemnified Person agrees to execute such documents as are necessary to permit the Indemnifying Person to control such defense). If the Indemnifying Person does not so assume control of such

defense, the Indemnified Person shall control such defense. The party not controlling such defense may participate therein at its own cost and expense; provided, that if the Indemnifying Person assumes control of such defense and the Indemnified Person is advised by counsel in writing that the Indemnifying Person and the Indemnified Person may have materially conflicting interests or different defenses available with respect to such action, suit or proceeding, the reasonable fees and expenses of one counsel to the Indemnified Person shall be considered "Damages" for purposes of this Agreement. The party controlling such defense shall keep the other party advised of the status of such action, suit or proceeding and the defense thereof and shall consider in good faith recommendations made by the other party with respect thereto. The Indemnifying Person shall not agree to any settlement or the entry of a judgment in any action, suit or proceeding without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld. The Provisions of this Section 8.6 shall be subject to the provisions of Schedule 1 to the Escrow Agreement

8.7 Damages; Mitigation. Notwithstanding anything herein or in the Escrow Agreement to the contrary, the amount of any Damages otherwise recoverable under Sections 8.4, 8.5 or 8.6 or in the Escrow Agreement by any Indemnified Person shall be reduced by (i) any amounts received by such Indemnified Person under insurance policies, it being understood that an Indemnified Person shall use its commercially reasonable best efforts to timely pursue all reasonable remedies against applicable insurers and (ii) the value of any tax benefit received by such Indemnified Person as a result of such Damages. In addition, any Indemnified Person shall use its commercially reasonable best efforts to mitigate any Damages subject to indemnification obligations under this Agreement or the Escrow Agreement.

9.3 Certain Definitions; Interpretation. In this Agreement, any reference to a "Material Adverse Effect" with respect to any entity or group of entities means any event, change or effect that is materially adverse to the condition (financial or otherwise), properties, assets (including intangible assets), liabilities, business, operations or results of operations of such entity; provided however, that none of the following shall be taken into account in determining whether there as been or will be a Material Adverse Effect: (a) any failure to meet internal projection or forecasts, (b) other than with respect to any threatened or instituted litigation, any adverse change, effect, event, occurrence state of facts or development to the extent attributable to the announcement or pendency of the transactions contemplated by this Agreement (including any disruption in, or termination or modification of, supplier, distributor, partner (including any partner under any OEM Agreement) or similar relationships or any loss of employees), (c) any adverse change, effect, event, occurrence, state of facts or development primarily attributable to conditions affecting the industry in which the entity participates or the U.S. economy as a whole; (d) any adverse change, effect, event, occurrence, state of facts or development attributable to or relating to any fees or expenses contemplated by this Agreement; or (e) any adverse change, effect, event, occurrence, state of facts or development resulting from or relating to compliance with the terms of, or the taking of any action required by, this Agreement. In this Agreement, any reference to "Ordinary Course of Business" shall mean an action taken by Company only if: (i) such action is generally consistent with the past practices of Company and is taken in the ordinary course of the normal day-to-day operations of Company, (ii) such action is not required to be authorized by the board of directors of Company, and (iii) such action is similar in nature and magnitude to actions customarily taken in the ordinary course of the normal day-to-day operations of other persons that are in substantially similar lines of business as Company. In this Agreement, any reference to "knowledge of Company" or "Company's knowledge" shall mean within the actual knowledge of each executive officer or director of Company after reasonable inquiry. When a reference is made in this Agreement to a Section, an Article, an Exhibit or a Schedule, such reference shall be to a Section or Article of this Agreement or an Exhibit or Schedule to this Agreement unless otherwise indicated. The words "include," "includes" and "including" when used herein shall be deemed in each case to be followed by the words "but are not limited to," "but is not limited to" and "but not limited to," respectively. 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.

9.4 Counterparts. This Agreement may be executed in one or more counterparts (including by means of facsimile), each of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

9.5 Entire Agreement; Parties in Interest; Nonassignability. This Agreement and the documents and instruments and other agreements specifically referred to herein or delivered pursuant hereto, including the Exhibits and Schedules and the Company Disclosure Schedule and the Parent Disclosure Schedule constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, including, without limitation, the Nondisclosure Agreement dated November 25, 2002 by and between Parent and Company. Neither this Agreement nor any right, interest or obligation hereunder may be assigned (by operation of law or otherwise) by any party without the prior written consent of the other party and any attempt to do so will be void; provided, however, that Parent may assign or transfer this Agreement to a successor corporation or other successor entity in the event of a merger, acquisition, asset sale, consolidation or other transfer related to a reorganization by Parent. Subject to the preceding sentence, this Agreement is binding upon, inures to the benefit of and is enforceable by the parties hereto and their respective successors and assigns.

9.6 Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future law, (i) such provision will be fully severable, (ii) this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (iii) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance therefrom, and (iv) in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible.

9.7 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

9.8 Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and therefore waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.
