AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER (the “Agreement”), made and entered into as of the 25^th day of October, 2002, by and among Stake Technology Ltd., a Canada corporation (“ACQUIROR”), Stake Acquisition Corp., a Delaware corporation (the “Acquisition Subsidiary”), and Opta Food Ingredients, Inc., a Delaware corporation (“OPTA”).

W I T N E S S E T H:

WHEREAS, the board of directors of each of ACQUIROR and Acquisition Subsidiary have approved, and declared it to be advisable and in the best interests of their respective stockholders, for Acquisition Subsidiary to consummate the Offer (as defined below) and the Merger (as defined below), upon the terms and subject to the conditions provided herein;

WHEREAS, the board of directors of OPTA has determined that it is in the best interests of OPTA and its stockholders to approve Acquisition Subsidiary’s proposed acquisition and has resolved (i) to recommend that the stockholders of OPTA accept the Offer (as defined below) and tender their shares (the “OPTA Shares”) of common stock, par value $.01 per share (the “OPTA Common Stock”), pursuant to the Offer and (ii) to approve and declare advisable the merger (the “Merger”) of Acquisition Subsidiary with and into OPTA, with OPTA being the surviving corporation (the “Surviving Corporation”), in accordance with the General Corporation Law of the State of Delaware (“DGCL”) following consummation of the Offer;

WHEREAS, in furtherance of the foregoing, Acquisition Subsidiary will make a cash tender offer (the “Offer”) in compliance with Section 14(d)(1) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder, to acquire all of the issued and outstanding OPTA Shares for $2.50 per OPTA Share (such amount, or any greater amount per OPTA Share paid pursuant to the Offer, being hereinafter referred to as the “Per Share Amount”), net to the seller in cash, upon the terms and subject to the conditions of this Agreement; and that the Offer will be followed by the Merger, pursuant to which each issued and outstanding OPTA Share not owned by Acquisition Subsidiary or ACQUIROR (other than Dissenting Shares (as defined below)) will be converted into the right to receive the Per Share Amount, upon the terms and subject to the conditions provided herein;

WHEREAS, as an inducement and a condition to ACQUIROR and Acquisition Subsidiary entering into this Agreement, contemporaneously with the execution and delivery of this Agreement certain stockholders of OPTA have entered into a Stockholders’ Agreement with ACQUIROR and Acquisition Subsidiary (the “Stockholders’ Agreement”) pursuant to which each such stockholder has, among other things, agreed to tender its OPTA Shares in the Offer, in each case upon the terms and subject to the conditions set forth in the Stockholders’ Agreement, and

WHEREAS, the board of directors of OPTA has received the opinion of ▇▇▇▇▇, ▇▇▇▇▇▇▇▇ & ▇▇▇▇, Inc. (“AH&H”) that the consideration to be received by the holders of OPTA Shares pursuant to the Offer and the Merger is fair to such holders from a financial point of view;

NOW, THEREFORE, in consideration of the premises, and the mutual covenants and agreements contained herein, the parties hereto do hereby agree as follows:

ARTICLE I

THE OFFER

1.1. The Offer.

(a) Not later than the first business day after the date of this Agreement, ACQUIROR, Acquisition Subsidiary and OPTA will make a public announcement of the Offer.

(b) Provided that this Agreement shall not have been terminated in accordance with Section 7.1 and none of the events set forth in Annex A hereto shall have occurred or be existing, Acquisition Subsidiary shall commence, and ACQUIROR shall cause Acquisition Subsidiary to commence, within the meaning of Rule 14d-2 under the Exchange Act, the Offer as promptly as practicable after the date hereof, but in no event later than five (5) business days after the initial public announcement of Acquisition Subsidiary’s intention to commence the Offer. The obligation of Acquisition Subsidiary to accept for payment and pay for OPTA Shares tendered pursuant to the Offer shall be subject only to the satisfaction of the conditions set forth in Annex A hereto (unless the failure of any such condition was caused by any breach by ACQUIROR or Acquisition Subsidiary of this Agreement in which case Acquisition Subsidiary shall be obligated to accept for payment and pay for OPTA Shares tendered pursuant to the Offer provided that such failure has been waived by OPTA), including the condition that a number of OPTA Shares representing that number of OPTA Shares which would equal more than fifty percent (50%) of the OPTA Shares then issued and outstanding on a fully-diluted basis shall have been validly tendered and not withdrawn prior to the expiration date of the Offer (the “Minimum Condition”). Acquisition Subsidiary expressly reserves the right to waive any such condition, to increase the Per Share Amount and to make any other changes in the terms and conditions of the Offer; provided, however, that, without the prior written consent of OPTA, Acquisition Subsidiary will not (i) decrease the Per Share Amount, (ii) reduce the maximum number of OPTA Shares to be purchased in the Offer, (iii) change the form of the consideration payable in the Offer, (iv) add to, modify or supplement the conditions to the Offer set forth in Annex A hereto, (v) extend the expiration date of the Offer beyond the twenty (20) business days following the commencement thereof, except as expressly provided herein, or (vi) make any other change in the terms or conditions of the Offer which is adverse to the holders of OPTA Shares. The Per Share Amount shall, subject to any applicable withholding of taxes, be net to each seller in cash, upon the terms and subject to the conditions of the Offer. Subject to the terms and conditions of the Offer, Acquisition Subsidiary shall, and ACQUIROR shall cause Acquisition Subsidiary to, accept for payment and pay, as promptly as practicable after expiration of the Offer, for all OPTA Shares validly tendered and not withdrawn.

(c) On the date of commencement of the Offer, ACQUIROR and Acquisition Subsidiary shall file with the Securities and Exchange Commission (the “SEC”) a Tender Offer Statement on Schedule TO, including all exhibits thereto (together with all amendments and

supplements thereto, the “Schedule TO”), with respect to the Offer. The Schedule TO shall contain or shall incorporate by reference an offer to purchase (the “Offer to Purchase”) and the forms of related letters of transmittal (the Schedule TO, the Offer to Purchase and such other documents, together with all supplements and amendments thereto, being referred to herein collectively as the “Offer Documents”). The Offer Documents will comply in all material respects with the provisions of applicable federal securities laws and, on the date filed with the SEC and on the date first published, sent or given to OPTA’s stockholders, shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. ACQUIROR and Acquisition Subsidiary shall correct promptly any information provided by any of them for use in the Offer Documents which shall become false or misleading, and ACQUIROR and Acquisition Subsidiary shall take all steps necessary to cause the Schedule TO, as so corrected, to be filed with the SEC and the other Offer Documents, as so corrected, to be disseminated to holders of OPTA Shares, in each case as and to the extent required by applicable law. OPTA and its counsel shall be given the reasonable opportunity to review and comment on the Offer Documents prior to the filing thereof with the SEC. ACQUIROR and Acquisition Subsidiary shall provide OPTA and its counsel with a copy of any written comments or telephonic notification of any oral comments ACQUIROR or Acquisition Subsidiary may receive from the SEC or its staff with respect to the Offer Documents promptly after the receipt thereof. ACQUIROR and its counsel shall provide OPTA and its counsel with a reasonable opportunity to participate in all communications with the SEC and its staff, including any meetings and telephone conferences, relating to the Offer Documents or this Agreement. In the event that ACQUIROR or Acquisition Subsidiary receives any comments from the SEC or its staff with respect to the Offer Documents, each shall use its reasonable best efforts to respond promptly to such comments and take all other actions necessary to resolve the issues raised therein.

(d) Subject to the terms and conditions hereof, the Offer shall remain open until midnight, Eastern Time, on the date that is twenty (20) business days after the Offer is commenced (within the meaning of Rule 14d-2 under the Exchange Act); provided, however, that without the prior written consent of OPTA, Acquisition Subsidiary may (i) extend the Offer, if at the scheduled expiration date of the Offer any of the conditions set forth in Annex A shall not have been satisfied or waived, for one (1) or more periods (none of which shall exceed ten (10) business days) not to exceed thirty (30) business days in the aggregate or, if earlier, until such time as such conditions are satisfied or waived, (ii) extend the Offer for one (1) or more periods, not to exceed thirty (30) business days in the aggregate, if required by any rule, regulation, interpretation or position of the SEC or the staff thereof applicable to the Offer, or (iii) extend the Offer on one (1) occasion for an aggregate period of not more than ten (10) business days beyond the latest expiration date that would otherwise be permitted under clause (i) or (ii) of this sentence if, on such expiration date, there shall not have been tendered that number of OPTA Shares which would equal more than ninety percent (90%) of the issued and outstanding OPTA Shares; provided, however, that if Acquisition Subsidiary shall extend the Offer pursuant to this clause (iii), Acquisition Subsidiary shall waive during such extension all conditions set forth in Annex A other than the Minimum Condition and the conditions set forth in paragraphs (a) or (d) in Annex A. If on the initial scheduled expiration date of the Offer or

any extension thereof, any applicable waiting period under any applicable foreign laws regulating competition, antitrust, investment or exchange controls has not expired or terminated prior to the expiration of the Offer (the “Foreign Antitrust Condition”), Acquisition Subsidiary shall, if requested to do so by OPTA, extend the expiration date of the Offer until a date not later than January 15, 2003 and ACQUIROR shall use its best efforts to obtain all permits, authorizations, consents, expiration or termination of waiting periods, and approvals as may be required by any Governmental Entity. In addition, ACQUIROR and Acquisition Subsidiary each agree that if all of the conditions set forth in Annex A are not satisfied, including the satisfaction of the Minimum Condition, on any expiration date of the Offer, then Acquisition Subsidiary shall, and ACQUIROR shall cause Acquisition Subsidiary to, extend the Offer for one (1) or more periods of not less than ten (10) business days if requested to do so by OPTA, provided that OPTA shall be entitled to make only three (3) such requests.

1.2. Action by OPTA.

(a) OPTA hereby approves of and consents to the Offer and represents and warrants that the board of directors of OPTA, at a meeting duly called and held, has, subject to the terms and conditions set forth herein, unanimously (i) determined that this Agreement and the transactions contemplated hereby, including the Offer and the Merger, are fair to, and in the best interests of, the stockholders of OPTA, (ii) approved the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby, including, without limitation, the Offer and the Merger, in all respects, and that such approval constitutes approval of the Offer, this Agreement and the Merger for purposes of Section 203 of the DGCL, and (iii) resolved to recommend that the stockholders of OPTA accept the Offer, tender their OPTA Shares to Acquisition Subsidiary and approve and adopt this Agreement and the Merger; provided, however, such approval and recommendation by the board of directors may be withdrawn, modified, or amended if OPTA shall have received a Superior Proposal (as defined in Section 5.2 hereof) or if the board of directors of OPTA otherwise determines in good faith, after consultation with its financial and legal advisors, that such action is necessary to comply with its fiduciary duties. OPTA consents to the inclusion of such approval and recommendation in the Offer Documents, subject to the foregoing proviso. OPTA further represents and warrants that AH&H has delivered to the board of directors of OPTA its written opinion dated October 16, 2002, that the cash consideration to be received by the stockholders of OPTA pursuant to the Offer and the Merger is fair from a financial point of view to such stockholders. OPTA has been authorized by AH&H to permit the inclusion of the fairness opinion or a reference thereto in the Offer Documents and the Schedule 14D-9 (as defined in Section 1.2(b)), subject to the foregoing proviso.

(b) Contemporaneously with the commencement of the Offer as provided in Section 1.1, OPTA hereby agrees to file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 pertaining to the Offer (together with any amendments or supplements thereto, the “Schedule 14D-9”) containing the recommendations described in Section 1.2(a), and to mail promptly the Schedule 14D-9 to the stockholders of OPTA. The Schedule 14D-9 will comply in all material respects with the provisions of applicable federal securities laws and, on the date filed with the SEC and on the date first published, sent or given to OPTA’s stockholders,

shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except that no representation is made by OPTA with respect to information supplied by ACQUIROR or Acquisition Subsidiary for inclusion in the Schedule 14D-9. OPTA, ACQUIROR and Acquisition Subsidiary each agrees to correct promptly any information provided by it for use in the Schedule 14D-9 if and to the extent that it shall have become false or misleading in any material respect and OPTA further agrees to take all steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC and disseminated to the holders of OPTA Shares, in each case as and to the extent required by applicable federal securities laws. ACQUIROR and its counsel shall be given a reasonable opportunity to review the Schedule 14D-9 prior to filing with the SEC. In addition, OPTA agrees to provide ACQUIROR and its counsel with any comments, whether written or oral, that OPTA or its counsel receives from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after the receipt of such comments or other communications.

(c) In connection with the Offer, OPTA will promptly furnish (or cause to be furnished) to ACQUIROR and Acquisition Subsidiary mailing labels, security position listings and any available listing or computer files containing the names and addresses of the record holders of OPTA Shares as of a recent date and shall furnish Acquisition Subsidiary with such additional information and assistance (including, without limitation, updated lists of stockholders, mailing labels and lists of securities positions) as Acquisition Subsidiary or its agents may reasonably request in communicating the Offer to the record and beneficial holders of OPTA Shares. Subject to the requirements of applicable law, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Offer and the Merger, ACQUIROR, Acquisition Subsidiary and their affiliates, associates, agents, representatives and advisors shall use the information contained in any such labels, listings and files only in connection with the Offer and the Merger and, if this Agreement shall be terminated, will deliver to OPTA all copies of such information, in whatever media, then in their possession.

1.3. OPTA Purchase Plan. Contingent upon the purchase of OPTA Shares by Acquisition Subsidiary pursuant to the Offer, OPTA shall amend its Amended and Restated Employee Stock Purchase Plan (the “OPTA Purchase Plan”) so that as of the Effective Time (i) the OPTA Purchase Plan will terminate and (ii) there will be no outstanding rights of participants under the OPTA Purchase Plan. Prior to the Effective Time, OPTA shall take all actions (including, if appropriate, amending the terms of the OPTA Purchase Plan) that are necessary to give effect to this Section 1.3.

1.4. Directors. Promptly upon the satisfaction of the Minimum Condition and the purchase by Acquisition Subsidiary of such Shares tendered in satisfaction of the Minimum Condition pursuant to the Offer, and from time to time thereafter as Shares are acquired by Acquisition Subsidiary, ACQUIROR shall be entitled to designate such number of directors of good repute, rounded down to the nearest whole number, on the board of directors as will give ACQUIROR, subject to compliance with Section 14(f) of the Exchange Act, representation on the board of directors equal to at least that number of directors which equals the product of the

total number of the currently serving directors on the board of directors (giving effect to the directors appointed or elected pursuant to this sentence and including current directors serving as officers of OPTA) multiplied by the percentage that the aggregate number of the OPTA Shares beneficially owned by ACQUIROR or any affiliate of ACQUIROR (including for purposes of this Section 1.4 such of the OPTA Shares as are accepted for payment pursuant to the Offer, but excluding OPTA Shares held by OPTA or any of its Subsidiaries) bears to the number of OPTA Shares outstanding; provided, that ACQUIROR shall not be entitled to designate a majority of the directors on the board of directors unless it and its affiliates beneficially own a majority of the shares of OPTA Common Stock outstanding. OPTA shall, upon request by ACQUIROR, promptly increase the size of the board of directors or exercise its best efforts to secure the resignations of such number of directors as is necessary to enable ACQUIROR’s designees to be elected to the board of directors in accordance with the terms of this Section 1.4 and shall use its best efforts to cause ACQUIROR’s designees to be so elected; provided, however, that, in the event that ACQUIROR’s designees are appointed or elected to the board of directors, until the Effective Time (as defined in Section 2.3 hereof) (x) ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇▇ and ▇▇▇▇▇ ▇. ▇▇▇▇▇▇ shall each continue to serve as a director of OPTA and (y) the board of directors shall have at least two directors who are directors on the date hereof and who are neither officers of OPTA nor designees, stockholders, affiliates or associates (within the meaning of the Federal securities laws) of ACQUIROR (such directors, the “Independent Directors”); provided, further, that if at any time or from time to time fewer than two Independent Directors remain, the other directors shall elect to the board of directors such number of persons who shall be neither officers of OPTA nor designees, stockholders, affiliates or associates of ACQUIROR so that the total of such persons and remaining Independent Directors serving on the board of directors is at least two. Any such person elected to the board of directors pursuant to the second proviso of the preceding sentence shall be deemed to be an Independent Director for purposes of this Agreement. Subject to applicable law, OPTA shall promptly take all action necessary pursuant to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order to fulfill its obligations under this Section 1.4 and shall include in the Schedule 14D-9 mailed to stockholders promptly after the commencement of the Offer (or an amendment thereof or an information statement pursuant to Rule 14f-1 if ACQUIROR has not theretofore designated directors) such information with respect to OPTA and its officers and directors as is required under Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this Section 1.4. ACQUIROR will supply OPTA any information with respect to itself and its nominees, officers, directors and affiliates required by Section 14(f) and Rule 14f-1. Notwithstanding anything in this Agreement to the contrary, following the time directors designated by ACQUIROR constitute a majority of the board of directors and prior to the Effective Time, the affirmative vote of a majority of the Independent Directors shall be required to (i) amend or terminate on behalf of OPTA this Agreement, (ii) exercise or waive any of OPTA’s rights or remedies hereunder, (iii) extend the time for performance of ACQUIROR’s or Acquisition Subsidiary’s obligations hereunder or (iv) take any other action required to be taken by the board of directors hereunder.

ARTICLE II

THE MERGER

2.1. The Merger. Upon the terms and conditions set forth in this Agreement, and in accordance with the DGCL, Acquisition Subsidiary shall be merged with and into OPTA at the Effective Time (as defined in Section 2.3). From and after the Effective Time, the separate corporate existence of Acquisition Subsidiary shall cease and OPTA shall continue as the Surviving Corporation under the name “Opta Food Ingredients, Inc.” and shall succeed to and assume all the rights and obligations of Acquisition Subsidiary and OPTA in accordance with the DGCL.

2.2. The Closing. The closing of the Merger (the “Closing”) will take place at 10:00 a.m. Eastern Time at the offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C. on the first business day after all of the conditions to the obligations of the parties to consummate the Merger as set forth in Article VI shall have been satisfied or waived, or on such other mutually agreeable later date as soon as practicable after the satisfaction or waiver of all conditions to the obligations of the parties to consummate the transactions contemplated hereby as set forth in Article VI (the “Closing Date”).

2.3. Effective Time. As promptly as practicable after the satisfaction or waiver of the conditions set forth in Article VI, the parties hereto shall cause the Merger to be consummated by filing a certificate of merger, or if applicable, a certificate of ownership and merger, with the Secretary of State of the State of Delaware, in such form as required by, and executed in accordance with the relevant provisions of, the DGCL (the time of such filing, or at such later time as ACQUIROR, Acquisition Subsidiary and OPTA shall agree should be specified in the merger document filed, being the “Effective Time”).

2.4. Effect of the Merger. From and after the Effective Time, the Surviving Corporation shall possess all the property, rights, privileges, powers and franchises and be subject to all of the restrictions, debts, liabilities, disabilities, obligations and duties of OPTA and Acquisition Subsidiary, and the Merger shall otherwise have the effects set forth in Section 259 of the DGCL.

2.5. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any further action on the part of the ACQUIROR, Acquisition Subsidiary, OPTA, the Surviving Corporation or any holder of OPTA Shares or any shares of capital stock of Acquisition Subsidiary:

(a) Acquisition Subsidiary Common Stock. Each share of capital stock of Acquisition Subsidiary issued and outstanding immediately prior to the Effective Time shall be converted into one fully paid and nonassessable share of common stock of the Surviving Corporation.

(b) Cancellation of Stock. Each OPTA Share that is held by OPTA (as treasury stock or otherwise) or held by ACQUIROR or Acquisition Subsidiary or by any direct or indirect

wholly-owned subsidiary of OPTA, ACQUIROR or Acquisition Subsidiary, shall automatically be canceled and retired and shall cease to exist, and no cash or other consideration shall be delivered in exchange therefor.

(c) Conversion of OPTA Shares. Each OPTA Share issued and outstanding immediately prior to the Effective Time (other than OPTA Shares to be canceled in accordance with Section 2.5(b) and Dissenting Shares) (as defined below) shall be canceled, extinguished and converted into and become a right to receive an amount equal to the Per Share Amount in cash, without interest (the “Merger Consideration”).

(d) Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, OPTA Shares outstanding immediately prior to the Effective Time held by a holder (if any) who is entitled to demand, and who properly demands, appraisal for such OPTA Shares in accordance with Section 262 of the DGCL (“Dissenting Shares”) shall not be converted into a right to receive the Merger Consideration unless such holder fails to perfect or otherwise loses such holder’s right to appraisal, if any. Such stockholders shall be entitled to receive payment of the appraised value of such OPTA Shares held by them in accordance with the provisions of such Section 262. If, after the Effective Time, such holder fails to perfect or loses any such right to appraisal, such OPTA Shares shall be treated as if they had been converted as of the Effective Time into the right to receive the Merger Consideration pursuant to Section 2.5(c).

OPTA shall give ACQUIROR (i) prompt notice of any written demands for appraisal or payment of the fair value of any OPTA Shares, withdrawals of such demands, and any other instruments served pursuant to the DGCL received by OPTA and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. OPTA shall not voluntarily make any payment with respect to any demands for appraisal and shall not, except with the prior written consent of ACQUIROR, settle or offer to settle any such demands at a price per OPTA Share greater than the Per Share Amount.

(e) Stock Options. Prior to the Effective Time, OPTA shall use its commercially reasonable efforts to provide that each outstanding option to purchase OPTA Shares (in each case, a “OPTA Option”) granted under OPTA’s 1992 Employee, Director and Consultant Stock Option Plan and its 1991 Non-Employee Stock Option Plan (together, the “Stock Option Plans”), whether or not then vested or exercisable, shall be exercisable for and entitle each holder thereof to, a payment in cash from the Surviving Corporation, upon exercise, equal to the product of (i) the number of OPTA Shares previously subject to such OPTA Option and (ii) the excess, if any, of the Merger Consideration over the exercise price per OPTA Share previously subject to such OPTA Option (such product, the “Net Gains”). All applicable withholding taxes attributable to the payments made hereunder shall be deducted from the amounts payable hereunder; provided, however, that with respect to any person subject to Section 16 of the Exchange Act, any such amount shall be paid as soon as practicable after the first date payment can be made without liability to such person under Section 16(b) of the Exchange Act. Immediately prior to the Effective Time, ACQUIROR shall provide or cause to be provided to OPTA the funds necessary to pay the aggregate amount of Net Gains attributable to all OPTA Options that OPTA becomes obligated to pay pursuant to this Section 2.5(e). OPTA shall make all payments of Net Gains

required by this Section 2.5(e) immediately prior to the Effective Time, although it shall deduct and withhold from the amounts otherwise payable pursuant to this Section 2.5(e) such amounts as it is required to deduct and withhold with respect to the making of such payments under the Internal Revenue Code of 1986 (the “Code”) or any other applicable state, local or federal tax law or tax laws of foreign jurisdictions. To the extent that amounts are so withheld by OPTA, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the OPTA Option in respect of which such withholding was made by OPTA. The Surviving Corporation will promptly comply with all tax laws requiring it to forward such withheld taxes and/or pay its own taxes to the responsible Governmental Entity, as well as reporting the amount of income resulting from the payments made pursuant to this Section 2.5(e).

2.6. Surrender of Securities; Funding of Payments; Stock Transfer Books.

(a) Exchange Agent. Pursuant to an agreement reasonably satisfactory to OPTA and ACQUIROR entered into prior to the Effective Time (the “Exchange Agent Agreement”), ACQUIROR shall designate a bank or trust company reasonably acceptable to OPTA to act as agent (the “Exchange Agent”) for the purpose of exchanging Certificates (as defined below) for the Merger Consideration. The fees and expenses of the Exchange Agent shall be paid by ACQUIROR and ACQUIROR shall indemnify the Exchange Agent and OPTA against actions taken by the Exchange Agent pursuant hereto and pursuant to the Exchange Agent Agreement other than for acts or omissions which constitute willful misconduct or gross negligence, pursuant to the Exchange Agent Agreement.

(b) Payment Fund. Prior to the Effective Time, the ACQUIROR shall remit to the Exchange Agent an amount equal to the aggregate Merger Consideration (including the aggregate Merger Consideration for all Dissenting Shares) necessary to pay the holders of the Certificates representing OPTA Shares (collectively, the “Payment Fund”). ACQUIROR shall be entitled to receive from the Exchange Agent any interest accrued on the Payment Fund.

(c) Letter of Transmittal; Procedure for Exchange. ACQUIROR agrees that, as soon as practicable after the Effective Time and in no event later than five (5) business days thereafter, the Surviving Corporation shall cause the distribution to holders of record of OPTA Shares (as of the Effective Time) of a form of letter of transmittal and other appropriate materials and instructions for use in effecting the surrender of a certificate or certificates which immediately prior to the Effective Time represented issued and outstanding OPTA Shares (each, a “Certificate”) for payment of the Merger Consideration therefor. Upon surrender to the Exchange Agent of a Certificate, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive, and the Exchange Agent shall promptly pay to the holders out of the Payment Fund, the Merger Consideration multiplied by the number of OPTA Shares represented by such Certificate immediately prior to the Effective Time, less any amounts required to be held pursuant to applicable tax laws. No interest shall accrue or be paid on the Merger Consideration payable upon the surrender of a Certificate for the benefit of the holder thereof. In the event any Certificate shall have been lost or destroyed, the Exchange Agent, subject to such other

conditions as the Surviving Corporation may reasonably impose (including the posting of an indemnity bond or other surety in favor of the Surviving Corporation with respect to the Certificate alleged to be lost or destroyed), shall be authorized to accept an affidavit from the record holder of such Certificate in a form reasonably satisfactory to the Surviving Corporation, and upon surrender to the Exchange Agent of such affidavit, together with a letter of transmittal duly completed and validly executed in accordance with the instructions thereto, the Exchange Agent shall promptly pay to the record holder of such Certificate out of the Payment Fund the Merger Consideration multiplied by the number of OPTA Shares represented by such Certificates immediately prior to the Effective Time, less any amounts required to be held pursuant to applicable tax laws.

(d) Payment to Registered Holders. If any portion of the Merger Consideration is to be paid to a person other than the person in whose name a Certificate is registered, it shall be a condition to such payment that such Certificate shall be surrendered and shall be properly endorsed or shall be otherwise in proper form for transfer and that the person requesting such payment shall have paid any transfer and other taxes required by reason of such payment in a name other than that of the registered holder of the certificate or instrument surrendered or shall have established to the satisfaction of the Surviving Corporation and the Exchange Agent that such tax either has been paid or is not payable.

(e) Stock Transfer Books Closed. At the Effective Time, the stock transfer books of OPTA shall be closed and there shall not be any further registration of transfers of OPTA Shares thereafter on the records of OPTA.

(f) No Dividends. After the Effective Time, no dividends, interest or other distributions shall be paid to the holder of any OPTA Shares.

(g) No Further Rights. After the Effective Time, holders of Certificates shall cease to have any rights as stockholders of OPTA, except as provided herein or under the DGCL. No interest shall be paid on any Merger Consideration payable to former holders of OPTA Shares.

(h) Termination of Payment Fund. Promptly following the two-year anniversary date of the Effective Date, the Exchange Agent shall return to the Surviving Corporation all of the remaining Payment Fund, and the Exchange Agent’s duties shall terminate. Thereafter, each holder of a Certificate may surrender the same to the Surviving Corporation and upon such surrender (subject to applicable abandoned property, escheat or similar laws) shall receive the applicable aggregate Merger Consideration. Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto shall be liable to any former holder of OPTA Shares for any amount delivered to a public official pursuant to applicable abandoned property, escheat or similar law.

2.7. Certificate of Incorporation of Surviving Corporation. At the Effective Time, the restated certificate of incorporation of OPTA shall be amended to read in its entirety as set forth in Exhibit A hereto. The restated certificate of incorporation of OPTA, as so amended, shall be the certificate of incorporation of the Surviving Corporation from and after the Effective Time and, subject to the limitations set forth in Section 5.9, until thereafter amended as provided

by law.

2.8. Bylaws of the Surviving Corporation. Subject to Section 5.9, the bylaws of Acquisition Subsidiary shall be the bylaws of the Surviving Corporation from and after the Effective Time of the Merger and until thereafter altered, amended or repealed as provided by law.

(c) Subject to Section 5.3(a) and Section 5.3(b), if required by applicable law, as soon as practicable following consummation of the Offer, OPTA shall file the Proxy Statement with the SEC under the Exchange Act, and shall use its reasonable best efforts to have the Proxy Statement cleared by the SEC.

(b) Any and all information obtained by ACQUIROR or Acquisition Subsidiary shall be subject to the provisions of the confidentiality agreement between a wholly-owned subsidiary of ACQUIROR and AH&H (on behalf of and as agent for OPTA) dated May 8, 2002 (the “Confidentiality Agreement”), which agreement remains in full force and effect and is hereby ratified and affirmed by the parties hereto.

5.5. Foreign Competition Laws. ACQUIROR and OPTA shall promptly make all filings required by each of them under any applicable foreign competition laws with respect to the Offer, the Merger and the transactions contemplated hereby, and shall cooperate with each other in connection with the making of all such filings.

received the prior written invitation or approval of a majority of the board of directors of OPTA) (i) solicit, seek or offer to effect, or effect, (ii) negotiate with or provide any information to the board of directors of OPTA, any director or officer of OPTA, any stockholder of OPTA, any employee or union or other labor organization representing employees of OPTA or any other person with respect to, (iii) make any statement or proposal, whether written or oral, either alone or in concert with others, to the board of directors of OPTA, any director or officer of OPTA or any stockholder of OPTA, any union or other labor organization representing employees of OPTA or any other person with respect to, or (iv) make any public announcement (except as required by law) or proposal or offer whatsoever (including, but not limited to, any “solicitation” of “proxies” as such terms are defined or used in Regulation 14A under the Exchange Act) with respect to:

(a) any form of business combination or transaction involving OPTA or any affiliate thereof, including, without limitation, a merger, tender or exchange offer or liquidation of OPTA’s assets;

(b) any form of restructuring, recapitalization or similar transaction with respect to OPTA or any affiliate thereof;

5.8. Public Disclosures. ACQUIROR and OPTA will consult with each other before issuing any press release or otherwise making any public statement with respect to the Offer, the Merger and other transactions contemplated by this Agreement, and shall not issue any such press release or make any such public statement prior to such consultation except as may be required by applicable law or requirements of any exchange upon which the OPTA Shares are traded. The parties shall issue a joint press release, mutually acceptable to ACQUIROR and OPTA, promptly upon execution and delivery of this Agreement.

5.9. Indemnification and Insurance.

(a) (i) From and after the Effective Time, ACQUIROR shall indemnify, defend and hold harmless each director, officer, present and former employee (including any employee who serves or served in a fiduciary capacity of any Plans) and agents of OPTA and OPTA Subsidiaries (the “Indemnified Parties”) against all losses, expenses, claims, damages, liabilities or amounts that are paid in settlement of, with the approval of the ACQUIROR (which approval shall not unreasonably be withheld), or otherwise in connection with any claim, action, suit, proceeding or investigation, including liabilities in connection with any claim, action, suit, proceeding or investigation with respect to which ACQUIROR has withheld settlement approval (a “Claim”), based in whole or in part on the fact that such person is or was a director or officer of OPTA and arising out of actions or omissions occurring at or prior to the Effective Time (including, without limitation, the transactions contemplated by this Agreement) to the fullest extent permitted by applicable law and shall pay expenses in advance of the final disposition of any such action or proceeding to each Indemnified Party upon receipt from the Indemnified Party to whom expenses are advanced of an undertaking to repay such advances if it shall ultimately be determined in a final adjudication from which there is no right to appeal that the Indemnified Party is not entitled to indemnification under this Section 5.9(a).

(ii) Without limiting the foregoing, in the event any Claim (whether arising before or after the Effective Time) is brought against any Indemnified Party after the Effective Time (i) the Indemnified Parties may retain OPTA’s regularly engaged independent legal counsel, or other independent legal counsel satisfactory to them, provided that such other counsel shall be reasonably acceptable to ACQUIROR, (ii) ACQUIROR shall pay all reasonable fees and expenses of such counsel for the Indemnified Parties promptly as statements therefor are received and (iii) ACQUIROR will use its reasonable best efforts to assist in the vigorous defense of any such matter. Any Indemnified Party wishing to claim indemnification under this Section 5.9(a) upon learning of any such Claim, shall notify ACQUIROR (although the failure so to notify ACQUIROR shall not relieve ACQUIROR from any liability which ACQUIROR may have under this Section 5.9(a) except to the extent such failure materially prejudices ACQUIROR), and shall deliver to ACQUIROR the undertaking contemplated by subsection (a)(i) hereof. The Indemnified Parties as a group may retain one law firm (in addition to local counsel) to represent them with respect to each such matter unless there is, under applicable standards of professional conduct (as determined by counsel to the Indemnified Parties), a conflict on any significant issue between the positions of any two or more Indemnified Parties, in which event, such additional counsel as may be required may be retained by the Indemnified Parties.

(b) Subject to the occurrence of the Effective Date, until the six year anniversary date of the Effective Time, the ACQUIROR and the Surviving Corporation agree that all rights to indemnification or exculpation now existing in favor of the Indemnified Parties as provided in the respective charters or by-laws or otherwise in effect as of the date hereof shall survive the Merger and shall continue in full force and effect, and ACQUIROR shall cause the Surviving Corporation to keep in effect all such indemnification and exculpation provisions to the fullest extent permitted under applicable law, which provisions shall not be amended, repealed or otherwise modified for such six-year period after the Effective Time, except as required by applicable law or except to make changes permitted by applicable law that would enlarge the exculpation or rights of indemnification thereunder. To the maximum extent permitted by the

DGCL, such indemnification shall be mandatory rather than permissive and the Surviving Corporation shall advance expenses as incurred to the fullest extent permitted under applicable law in connection with such indemnification.

(c) For a period of six years after the Effective Time, the ACQUIROR shall cause the Surviving Corporation and the Surviving Corporation shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by OPTA (or policies of at least the same coverage and amounts containing terms and conditions which are no less advantageous) with respect to claims arising from facts or events which occurred before the Effective Time.

(d) ACQUIROR agrees to be jointly and severally liable with the Surviving Corporation for its indemnification obligations to the Indemnified Parties.

(e) This Section 5.9 is intended to be for the benefit of, and shall be enforceable by, the Indemnified Parties, their heirs and personal representatives and shall be binding on ACQUIROR and Acquisition Subsidiary and the Surviving Corporation and their respective successors and assigns.

(f) In the event ACQUIROR or the Surviving Corporation or any of their successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of ACQUIROR or the Surviving Corporation, as the case may be, or at ACQUIROR’s option, ACQUIROR, shall assume the obligations set forth in this Section 5.9.

(g) ACQUIROR shall pay all reasonable expenses incurred by any Indemnified Parties in connection with the enforcement of the provisions of this Section 5.9.

5.10. Reasonable Best Efforts. Subject to the fiduciary duties of the board of directors of OPTA as determined by the board of directors of OPTA after consultation with its legal counsel, each of the parties hereto agrees to use its reasonable best efforts to take, or cause to be taken, all necessary or appropriate action, and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations or otherwise to consummate and make effective the Offer, the Merger and all other transactions contemplated by this Agreement including, without limitation, the execution of any additional instruments necessary to consummate the transactions contemplated hereby and seeking to lift, rescind or reverse any legal restraint imposed on the consummation of the transactions contemplated by this Agreement. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and directors of each party hereto shall take all such necessary action.

5.11. Notice of Subsequent Events. OPTA shall give prompt notice to ACQUIROR or Acquisition Subsidiary, and ACQUIROR or Acquisition Subsidiary shall give prompt notice to OPTA, as the case may be, of (i) the occurrence, or non-occurrence, of any event the respective

occurrence, or non-occurrence, of which would be likely to cause any condition contained in this Agreement to be unsatisfied and (ii) any failure of OPTA, ACQUIROR or Acquisition Subsidiary, as the case may be, to comply with or satisfy any covenant or agreement to be complied with under this Agreement; provided, however, that the delivery of any notice pursuant to this Section 5.11 shall not relieve any party giving such notice of its obligation hereunder.

5.12. Employment; Employee Welfare.

(a) ACQUIROR agrees to offer employment to all those persons employed by OPTA or OPTA Subsidiaries (including both full-time and part-time employees and employees on leave) at the time of the Closing, at levels of salary and benefits which are substantially comparable to the salary and benefits paid or provided to such persons by OPTA or OPTA Subsidiaries immediately prior to the Closing; provided that it is understood by OPTA that ACQUIROR does not currently have, or intend to adopt, an employee stock purchase plan.

(b) ACQUIROR will cause the Surviving Corporation to maintain following the Closing Date employee compensation and benefit plans (including bonus plans), programs, policies and fringe benefits (including any post-employment benefits) that are substantially equivalent to those provided to such employees of OPTA and OPTA Subsidiaries, as applicable, under the Plans as in effect immediately prior to the Closing (the “Existing Plans”), subject to the right to amend or terminate such Existing Plans in accordance with their terms, provided that after any such amendment or termination such programs, policies and fringe benefits continue to be, in the aggregate, substantially equivalent to the Existing Plans.

(c) ACQUIROR will cause the Surviving Corporation to provide to all employees of OPTA and OPTA Subsidiaries severance pay and benefits which are equivalent to the applicable severance plans, programs, agreements and policies of OPTA and the OPTA Subsidiaries, as applicable, as in effect immediately prior to the Closing (the “Existing Severance Benefits”), subject to the right to amend or terminate such Existing Severance Benefits in accordance with their terms, provided that after any such amendment or termination such severance pay and benefits continue to be substantially equivalent to the Existing Severance Benefits. Further, ACQUIROR shall credit the prior service of all employees of OPTA and OPTA Subsidiaries to OPTA and the OPTA Subsidiaries, as applicable, for purposes of determining the eligibility, vesting or qualification of such employees of OPTA and OPTA Subsidiaries under Existing Plans, Existing Severance Benefits and any successor plans and benefit programs.

(d) From and after the Effective Time, ACQUIROR and the Surviving Corporation shall assume and honor in accordance with their terms all existing employment, severance, bonus and similar agreements and arrangements set forth in Section 5.12(d) of the OPTA Disclosure Schedule.

(e) ACQUIROR shall reimburse (or cause the Surviving Corporation to reimburse) any director, officer or employee (or former director, officer or director) of OPTA or any OPTA

Subsidiaries for all costs and expenses, including attorneys’ fees, incurred by such person in successfully enforcing the provisions of this Section 5.12.

(h) by OPTA if any representation or warranty of ACQUIROR or Acquisition Subsidiary in this Agreement shall not be true and correct on the date of this Agreement, or ACQUIROR or Acquisition Subsidiary shall have failed to perform in any material respect any obligation or to comply in any material respect with any agreement or covenant of ACQUIROR or Acquisition Subsidiary to be performed or complied with by it under this Agreement; provided that such breach or failure to perform (if curable) has not been cured within thirty (30) calendar days after notice to ACQUIROR.

Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party.

(b) “Including.” The word “including,” when following any general statement, term or matter, shall not be construed to limit such statement, term or matter to the specific terms or matters as provided immediately following the word “including” or to similar items or matters, whether or not non-limiting language (such as “without limitation,” “but not limited to,” or words of similar import) is used with reference to the word “including” or the similar items or matters, but rather shall be deemed to refer to all other items or matters that could reasonably fall within the broadest possible scope of the general statement, term or matter.

(c) “Knowledge.” “To the knowledge,” “to the best knowledge, information and belief,” or any similar phrase shall be deemed to refer to the actual knowledge of the Chief Executive Officer and the Chief Financial Officer of OPTA and the OPTA Subsidiaries who in the ordinary course of their duties and after reasonable inquiry would have knowledge of the accuracy of such representation and that nothing has come to the attention of such officers which would give such officers reason to believe that the fact referred to is not accurate.

8.10. Integration of Schedules.

8.13. Validity. If any provision of this Agreement, or the application thereof to any person or circumstance, is held invalid or unenforceable, the remainder of this Agreement, and the application of such provision to other persons or circumstances, shall not be affected thereby, and to such end, the provisions of this Agreement are agreed to be severable.

8.14. Counterparts. This Agreement may be executed in several counterparts, each of which, when so executed, shall be deemed to be an original, and such counterparts shall, together, constitute and be one and the same instrument.

with Section 1.1(d) and thereby postpone acceptance for payment or purchase of OPTA Shares while exercising such best efforts;

(b) the board of directors (i) shall have withdrawn, or modified or changed in a manner materially adverse to ACQUIROR or Acquisition Subsidiary (whether or not included in an amendment of the Schedule 14D-9) its approval or recommendation of this Agreement or the Stockholders’ Agreement or the transactions contemplated hereby or thereby, including the Offer or the Merger, (ii) shall have recommended an Acquisition Proposal other than a Superior Proposal or (iii) shall have adopted any resolution to effect any of the foregoing; provided, that the foregoing shall not apply solely as a result of OPTA or the board of directors making such disclosure to OPTA’s stockholders as, in the good faith judgment of the board of directors, after receiving advice from outside counsel, is required under applicable law;

(c) there shall have occurred any event that, individually or when considered together with any other matter, has or has had a Material Adverse Effect upon OPTA or a OPTA subsidiary;

(d) OPTA shall have breached or failed to perform in any material respect any of its material covenants or agreements under the Agreement;

(e) any of the representations and warranties of OPTA set forth in the Agreement which are qualified as to Material Adverse Effect shall not be true and correct when made and as of the expiration of the Offer, or any of the other representations and warranties of OPTA set forth in the Agreement shall not be true and correct when made and as of the expiration of the Offer, which failure would have a Material Adverse Effect (except in each case in the case of representations and warranties of OPTA which address matters only as of a particular date, which need only be true and correct as aforesaid as of such date);

(f) this Agreement shall have been terminated in accordance with its terms;

(g) ACQUIROR, Acquisition Subsidiary and OPTA shall have agreed in writing that Acquisition Subsidiary shall terminate the Offer or postpone the acceptance for payment of or the payment for OPTA Shares thereunder; or

(h) there shall have occurred (i) any general suspension of, or limitation on prices for trading in securities on the New York Stock Exchange, American Stock Exchange, any national securities exchange or on the Nasdaq National Market System for a period in excess of 24 hours (excluding any suspension or limit resulting solely from physical damage or interference with such exchanges not related to market conditions), (ii) a declaration of a banking moratorium or any suspension of payments in respect of banks in the United States, or (iii) a change in the general financial, bank or capital markets which materially and adversely affects the ability of financial institutions in the United States to extend credit or syndicate loans.
