(a) The Seller Corporations shall not directly or indirectly, and shall not authorize or permit any of their Representatives directly or indirectly to, (i) solicit, initiate, encourage, induce or facilitate the making, submission or announcement of any Acquisition Proposal or take any action that could reasonably be expected to lead to an Acquisition Proposal, (ii) furnish any information regarding any of the Seller Corporations to any Person in connection with or in response to an Acquisition Proposal or an inquiry or indication of interest that could lead to an Acquisition Proposal, (iii) engage in discussions or negotiations with any Person with respect to any Acquisition Proposal, (iv) approve, endorse or recommend any Acquisition Proposal or (v) enter into any letter of intent or similar document or any Contract contemplating or otherwise relating to any Acquisition Transaction; provided, however, that this Section 5.7 shall not be deemed to prevent the Seller or its board of directors from complying with its legal obligations under Rules 14d-9 and 14e-2 as promulgated under the Exchange Act with regard to an Acquisition Proposal (it being understood that such compliance may constitute a Triggering Event under certain circumstances); and provided, further, that prior to the Closing, this Section 5.7(a) shall not prohibit the Seller from furnishing nonpublic information regarding the Seller to, or entering into discussions with, any Person in response to a Superior Offer that is submitted to the Seller by such Person (and not withdrawn) if (1) neither the Seller nor any Representative of the Seller shall have breached in a material respect or taken any action inconsistent with any of the provisions set forth in this Section 5.7, (2) the board of directors of the Seller concludes in good faith, after having consulted with its outside legal counsel, that such action is required in order for the board of directors of the Seller to comply with its fiduciary obligations to the Seller’s stockholders under applicable law, (3) at least five (5) business days prior to furnishing any such nonpublic information to, or entering into discussions with, such Person, the Seller gives Parent and the Purchaser written notice of the identity of such Person and of the Seller’s intention to furnish nonpublic information to, or enter into discussions with, such Person, and the Seller receives from such Person an executed confidentiality agreement containing customary limitations on the use and disclosure of all nonpublic written and oral information furnished to such Person by or on behalf of the Seller and containing provisions no less favorable to the Seller than the provisions contained in that certain Letter of Intent, dated February 3, 2003, between the Seller and Parent (the “Confidentiality Agreement”), and (4) at least five (5) business days prior to furnishing any such nonpublic information to such Person, the Seller furnishes such nonpublic information to Parent and the Purchaser (to the extent such nonpublic information has not been previously furnished by the Seller to Parent and the Purchaser). Without limiting the generality of the foregoing, the Seller acknowledges and agrees that any action inconsistent with any of the provisions set forth in the preceding sentence by any Representative of the Seller, whether or not such Representative is purporting to act on behalf of the Seller, shall be deemed to constitute a breach of this Section 5.7 by the Seller.

(b) The Seller shall promptly (and in no event later than twenty-four (24) hours after receipt of any Acquisition Proposal, any inquiry or indication of interest that could reasonably be expected to lead to an Acquisition Proposal) advise Parent and the Purchaser orally and in writing of any Acquisition Proposal, any inquiry or indication of interest that could

-26-

reasonably be expected to lead to an Acquisition Proposal or any request for nonpublic information relating to the Seller (including the identity of the Person making or submitting such Acquisition Proposal, inquiry, indication of interest or request, and the terms thereof) that is made or submitted by any Person during the Pre-Closing Period. The Seller shall keep Parent and the Purchaser fully informed with respect to the status of any such Acquisition Proposal, inquiry, indication of interest or request and any modification or proposed modification thereto.

5.9 Bulk Sales Laws. Prior to the Closing, Seller shall comply with the requirements of all Bulk Sales Laws.

6. Additional Covenants of the Parties.

6.1 Registration Requirements.

(a) Obligations of Parent.

(1) As soon as reasonably practicable after the Closing, Parent shall file a registration statement (the “Registration Statement”) with the SEC to effect the registration under the Securities Act of the shares of Parent’s Common Stock issuable in the Transaction (together with any shares of Parent Common Stock issued in connection with any stock dividend, split, combination or recapitalization on, of or with respect to shares of Parent’s Common Stock issuable in the Transaction, collectively, the “Registrable Shares”), for sale by the Seller. Parent shall use its commercially reasonable efforts to file the Registration Statement no later than

-27-

twenty (20) days after the Closing Date. After the Registration Statement is filed, Parent shall respond reasonably promptly to any and all comments made by the staff of the SEC to such Registration Statement. In connection with the Registration Statement:

(i) Such Registration Statement shall comply in all material respects with the requirements of the Securities Act and the rules and regulations of the SEC promulgated thereunder.

(ii) If the Registration Statement receives a “no review” from the SEC, Parent will request that the SEC declare the Registration Statement effective within three (3) business days following the SEC’s confirmation of the “no review” status. If the SEC reviews the Registration Statement, Parent will use commercially reasonable efforts to cause the Registration Statement to be declared effective within forty-five (45) days after the filing date. If, however, Parent decides to file a registration statement for a primary offering of Parent’s stock within such forty-five (45) day period, Parent shall have the right, in its discretion, to withdraw the Registration Statement; and

(iii) Parent will keep the Registration Statement effective to sell Registrable Shares, until the earlier of (A) such date as all of the Registrable Shares have been resold or (B) one (1) year from the Closing Date.

(2) If the Registration Statement pursuant to Section 6.1(a)(1) hereof is withdrawn and if Parent shall determine to register any of its securities either for its own account or the account of a security holder or holders, other than a registration relating solely to employee benefit plans, or a registration relating solely to a Rule 145 transaction, or a registration on any registration form that does not permit secondary sales, Parent will (i) promptly give to the Seller written notice thereof; and (ii) use its best efforts to include in such registration (and any related qualification under blue sky laws or other compliance) and in any underwriting involved therein, all of the Registrable Shares. If the Registration Statement of which Parent gives notice is for a registered public offering involving an underwriting:

(i) Parent shall so advise the Seller as a part of the written notice given pursuant to Section 6.1(a)(2) hereof;

(ii) In such event, the right of the Seller to include its Registrable Shares in the Registration Statement pursuant to this Section 6.1(a)(2) shall be conditioned upon the Seller’s participation in such underwriting and the inclusion of the Registrable Shares held by Seller in the underwriting to the extent provided herein. The Seller shall (together with Parent) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by Parent.

Notwithstanding any other provision of this Section 6.1(a)(2), if the representative of the underwriters advises Parent in writing that marketing factors require a limitation on the number of shares to be underwritten, the representative may exclude all Registrable Shares from, or limit the number of the Registrable Shares to be included in, the offering of the Registration Statement and underwriting or may include such shares only in the underwriter’s over-allotment option. Parent shall so advise the Seller of the number of shares of

-28-

Registrable Shares that are entitled to be included in the offering of the Registration Statement and underwriting, and, if applicable, the number of shares to be included in the over-allotment option. If the Seller does not agree to the terms of any such underwriting, the Seller shall be excluded therefrom by written notice from Parent or the underwriter. Any of the Registrable Shares excluded or withdrawn from such underwriting shall be withdrawn from such registration.

(3) If the Registrable Shares are not registered pursuant to Section 6.1(a)(1) hereof or sold in the primary offering or the underwriter’s over-allotment option of the Registration Statement pursuant to Section 6.1(a)(2) hereof, Parent shall file a Registration Statement with the SEC to effect the registration under the Securities Act of the Registrable Shares for sale by the Seller. Parent shall use its commercially reasonable efforts to file the Registration Statement no later than twenty (20) days after the end of the underwriter’s over-allotment option. After the Registration Statement is filed, Parent shall respond reasonably promptly to any and all comments made by the staff of the SEC to such Registration Statement. In connection with the Registration Statement:

(i) Such Registration Statement shall comply in all material respects with the requirements of the Securities Act and the rules and regulations of the SEC promulgated thereunder.

(ii) If the Registration Statement receives a “no review” from the SEC, Parent will request that the SEC declare the Registration Statement effective within three (3) business days following the SEC’s confirmation of the “no review” status. If the SEC reviews the Registration Statement, Parent will use commercially reasonable efforts to cause the Registration Statement to be declared effective within ninety (90) days after the Closing Date;

(iii) Parent shall not be required to conduct an underwritten offering; and

(iv) Parent will keep the Registration Statement effective to sell Registrable Shares, until the earlier of (A) such date as all of the Registrable Shares have been resold or (B) one (1) year from the effective date of the Registration Statement.

(4) Parent shall have no obligation to include the Registrable Shares owned by the Seller in any Registration Statement pursuant to this Section 6.1 unless and until the Seller has furnished Parent with all information and statements about or pertaining to the Seller in such reasonable detail and on such timely basis as is reasonably deemed by Parent to be necessary or appropriate for the preparation of the Registration Statement.

(5) Parent shall prepare and file with the SEC, as promptly as is commercially reasonably practicable, such amendments (including post-effective amendments) and supplements to the Registration Statement and the prospectus used in connection with any Registration Statement filed pursuant to this Section 6.1 as may be necessary to keep the Registration Statement effective during the application registration period, and, during such period, to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Shares covered by the Registration Statement.

-29-

(6) Parent shall furnish to the Seller (A) promptly after the same is prepared and filed with the SEC, one copy of the Registration Statement and any amendment thereto and each preliminary prospectus and each amendment or supplement thereto; (B) on the date of effectiveness of the Registration Statement or any amendment thereto, a notice, to the Seller, stating that the Registration Statement or amendment has been declared effective; and (C) such number of copies of a prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as the Seller may reasonably request in order to facilitate the disposition of the Registrable Shares owned by the Seller.

(7) Parent shall use commercially reasonable efforts to cause all Registrable Shares to be listed on each national securities exchange or quotation service on which securities of the same class or series issued by Parent are then listed.

(8) As promptly as practicable after becoming aware of such event, Parent shall notify the Seller of the happening of any event, of which Parent has knowledge, as a result of which the prospectus included in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and use commercially reasonable efforts to promptly prepare a supplement or amendment to the Registration Statement to correct such untrue statement or omission, and deliver such number of copies of such supplement or amendment to the Seller as the Seller may reasonably request.

(9) Parent shall use commercially reasonable efforts to prevent the issuance of any stop order or other suspension of effectiveness of the Registration Statement, and, if such an order is issued, to obtain the withdrawal of such order as soon as practicable (including in each case by amending or supplementing the Registration Statement) and to notify the Seller of the issuance of such order and the resolution thereof, and if the Registration Statement is supplemented or amended, deliver such number of copies of such supplement or amendment to the Seller as the Seller may reasonably request.

(10) Without limiting the generality of subsections (8) and (9) above, Parent may refuse to permit the Seller to resell any Registrable Shares pursuant to any Registration Statement at any time; provided, however, that in order to exercise this right at any time, Parent must notify the Seller to the effect that suspension of the sale of shares under the Registration Statement is necessary, and provided further that Parent shall only invoke this right to suspend the sale of shares under the Registration Statement where it in good faith determines that such a sale would be in violation of the requirements of the Securities Act and the regulations promulgated by the SEC thereunder. Notwithstanding the foregoing, Parent shall not under any circumstances be entitled to exercise its right to suspend sales under this subsection more than four (4) times in any twelve (12)-month period, and the period during which any Registration Statement under this subsection may be withdrawn shall not exceed sixty (60) days each such time.

(11) Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC that may permit the sale of the Registrable Shares to the public without registration, Parent agrees to use its best efforts to:

-30-

(i) Make and keep public information regarding Parent available as those terms are understood and defined in Rule 144 under the Securities Act, at all times;

(ii) File with the SEC in a timely manner all reports and other documents required of Parent under the Securities Act and the Exchange Act;

(iii) So long as the Seller owns any Registrable Shares, furnish to the Seller forthwith upon written request a written statement by Parent as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act a copy of the most recent annual or quarterly report of Parent, and such other reports and documents so filed as the Seller may reasonably request in availing itself of any rule or regulation of the SEC allowing the Seller to sell any such securities without registration.

(b) Covenant of the Seller. The Seller covenants that it will sell the Parent Common Stock pursuant only to institutional negotiated “block trades” and shall not sell any of the Parent Common Stock registered on the Registration Statement on the open market; provided, however, that in addition to “block trades,” the Seller shall be permitted to trade up to 100,000 shares of Parent Common Stock per month on the open market.

(c) Expenses of Registration. Parent shall pay all Registration Expenses (as defined below) in connection with any registration, qualification or compliance hereunder, and the Seller shall pay all Selling Expenses (as defined below) and other expenses that are not Registration Expenses relating to the Registrable Shares to be resold by the Seller. “Registration Expenses” shall mean all expenses, except for Selling Expenses, incurred by Parent in complying with the registration provisions set forth herein, including, without limitation, all registration, qualification and filing fees, printing expenses, escrow fees, fees and disbursements of counsel for Parent, blue sky fees and expenses and the expense of any special audits incident to or required in connection with any such registration. “Selling Expenses” shall mean selling commissions, underwriting fees, expenses of counsel to the Seller and stock transfer taxes applicable to the Registrable Shares.

6.2 Regulatory Approvals. Each party shall (i) use all reasonable efforts to file, as soon as practicable after the date of this Agreement, all notices, reports and other documents required to be filed by such party with any Governmental Body with respect to the Transactions, and to submit promptly any additional information requested by any such Governmental Body and (ii) cooperate with the other parties hereto and, subject to Section 6.3(b) hereof, use its reasonable efforts to take or cause to be taken all actions, and do or cause to be done all things, necessary, proper or advisable on its part under this Agreement and applicable Legal Requirements to consummate and make effective the Transactions. The Seller and Parent shall respond as promptly as practicable to (i) any inquiries or requests received from the Federal Trade Commission or the Department of Justice for additional information or documentation and (ii) any inquiries or requests received from any state attorney general, foreign antitrust authority or other Governmental Body in connection with antitrust or related matters. Each of the Seller and Parent shall (1) give the other party prompt notice of the commencement or known threat of commencement of any Legal Proceeding by or before any Governmental Body with respect to the Transactions, (2) keep the other party informed as to the status of any such Legal Proceeding

-31-

or threat, and (3) promptly inform the other party of any communication to or from the Federal Trade Commission, the Department of Justice or any other Governmental Body regarding the Transactions. Except as may be prohibited by any Governmental Body or by any Legal Requirement, (a) the Seller and Parent will consult and cooperate with one another, and will consider in good faith the views of one another, in connection with any analysis, appearance, presentation, memorandum, brief, argument, opinion or proposal made or submitted in connection with any Legal Proceeding under or relating to any domestic or other foreign, federal or state antitrust or fair trade law, and (b) in connection with any such Legal Proceeding, each of the Seller and Parent will permit authorized Representatives of the other party to be present at each meeting or conference with governmental representatives relating to any such Legal Proceeding and to have access to and be consulted in connection with any document, opinion or proposal made or submitted to any Governmental Body in connection with any such Legal Proceeding. The Seller and Parent may, as each reasonably deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other under this Section 6.2 as “outside counsel only.” Such materials and the information contained therein shall be given only to the outside legal counsel to the recipient and will not be disclosed by such outside counsel to employees, officers or directors of the recipient unless express permission is obtained in advance from the source of the materials (the Seller or Parent, as the case may be) or its legal counsel.

6.3 Additional Agreements.

(a) Subject to Section 6.3(b) hereof, the Seller, Parent and the Purchaser shall use all reasonable efforts to take, or cause to be taken, all actions necessary to consummate the Transactions.

Each party shall promptly deliver to the other party a copy of each such filing made, each such notice given and each such Consent obtained by the first party during the Pre-Closing Period.

(b) Notwithstanding anything to the contrary contained in this Agreement, neither Parent nor the Purchaser shall have any obligation under this Agreement: (i) to dispose of or transfer or cause any of its subsidiaries to dispose of or transfer any assets; (ii) to discontinue or cause any of its subsidiaries to discontinue offering any product or service; (iii) to license or otherwise make available, or cause any of its subsidiaries to license or otherwise make available, to any Person, any technology, software or other Proprietary Asset; (iv) to hold separate or cause any of its subsidiaries to hold separate any assets or operations (either before or after the Closing Date), or to commit to cause any of the Acquired Corporations to hold separate any assets or operations; (v) to make or cause any of its subsidiaries to make any commitment (to any Governmental Body or otherwise) regarding its future operations; or (vi) to contest any Legal Proceeding relating to the Transactions if Parent or the Purchaser determines in good faith that contesting such Legal Proceeding may, if adversely determined, have a material adverse effect on the business, operations, financial condition or prospects of Parent or the Purchaser.

Further, the Seller shall use its best efforts to cooperate with Parent in connection with the drafting, the content, and the filing of the stipulation to dismiss the Parent Pending Litigation as referenced in this Section 7.5(d). For purposes of this Section 7.5(d), “cooperate” shall mean that the Seller shall consult with and defer to Parent’s judgment and decisions concerning any terms and/or conditions which Parent believes should be included in the stipulation to dismiss the Parent Pending Litigation and/or the dismissal thereof.

(l) the Purchaser shall be satisfied, in its discretion, that none of the Assumed Contracts will grant to any third party any rights in Parent’s Proprietary Assets other than the Proprietary Assets the Purchaser is acquiring from the Seller in connection with the transaction contemplated by this Agreement.

7.6 Cooperation of the Seller in the Diodem Lawsuit. The Seller shall use its best efforts to cooperate with Parent concerning any claims, defenses, rights and/or remedies that Seller may have in connection with the civil action, Case No. CV03-2142 GAF (RCx), filed by Diodem LLC and against Lumenis Inc., Lumenis Ltd., Continuum, the Seller and others for patent infringement in the U.S. District Court for the Central District of California, Western Division (the “Diodem Lawsuit”).

The Seller shall give its approval to third parties, including, without limitation, licensees and attorneys of the Seller, to assist in these same matters. Parent agrees to indemnify the Seller to the extent of any direct liabilities to Diodem that arise out of Seller’s cooperation with directives of Parent to take action that Seller would not have otherwise taken with respect to Diodem, provided that as a condition to such indemnification, Seller hereby assigns to Parent any recovery, at law or in equity, obtained against third parties as a result of such directives of Parent. Further, any and all causes of action, claims, defenses, rights, remedies, proceedings, demands and/or judgments, of any nature, including, without limitation, any past or prior, present and/or future infringement actions asserted prior to or subsequent to the Closing Date, which are, or in the future may be, held by Seller, whether known or unknown, in connection with the Diodem Lawsuit, and/or the intellectual property at issue and/or referenced therein, will be on the Closing Date sold, assigned, conveyed, and/or transferred by Seller to Parent, except for any claims by seller against Diodem for damages based on the theory that the purchase price under this Agreement would have been higher if not for the Diodem lawsuit.
