Each of the Medicor Group, on behalf of the Medicor Parties, ERI, on behalf of the ERI Parties, and the Belfer Group, on behalf of the Belfer Parties, shall have the right to request registration under the Securities Act of all or part of their Registrable Securities on Form S-1 or any similar long-form registration or, if available, on Form S-2 or S-3 or any similar short-form registration ("Short-Form Registrations") in accordance with this Article III. All registrations requested pursuant to this Section 3.l(a) are referred to herein as "Demand Registrations." (b) Short-Form Registrations. Demand Registrations will be Short-Form Registrations whenever the Company is permitted to use any applicable short form. The Company will use its best efforts to make Short-Form Registrations available for the sale of Registrable Securities. Demand Registration requests may be for shelf registrations if the Company is then eligible to effect shelf registrations. (c) Restrictions on Demand Registrations. The registration rights granted under this Section 3.1 are expressly subject to the following terms and conditions: 1. The Company will not be obligated to effect any Demand Registration within six (6) months after the effective date of a previous Demand Registration (including any registration or offering of shares pursuant to the ERI letter to the Company dated September 11, 2003 (the "ERI Letter") to the extent such registration or offering would constitute a "Demand Registration" under and as defined in the Shareholders Agreement, provided that solely for purposes of making such determination the registration requested in the ERI Letter shall be deemed to have satisfied the requirements for an effective "Demand Registration" set forth in Section 5.1(c)(3) of the Shareholders Agreement). 2. The Company may postpone for up to ninety (90) days the filing or the effectiveness of a registration statement for a Demand Registration (and any registration or underwritten offering of securities pursuant to Section 3.1(c)(6), whether or not such registration or underwritten offering constitutes a Demand Registration) if the Company notifies the 6 Shareholder Party initiating the Demand Registration (or such other registration or underwritten offering pursuant to Section 3.1(c)(6)) within fifteen (15) days after receipt of request for such registration (i) that the Company is at such time conducting or about to conduct an underwritten public offering of its securities for its own account and the Board of Directors has determined in its good faith judgment that such offering would be materially adversely affected by such registration or underwritten offering requested by such Shareholder Party or (ii) that the Board of Directors has determined, in its good faith judgment, that such Demand Registration (or registration or underwritten offering pursuant to Section 3.1(c)(6)) would reasonably be expected to have an adverse effect on any proposal or plan by the Company or any of its Subsidiaries to engage in any acquisition of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer or similar transaction; provided, that, in such event, the holders of Registrable Securities initially requesting such Demand Registration (or, to the extent it would count as a Demand Registration, such registration or underwritten offering pursuant to Section 3.1(c)(6)) will be entitled to withdraw such request and, if such request is withdrawn, such Demand Registration (or registration or underwritten offering pursuant to Section 3.1(c)(6)) will not count as a Demand Registration hereunder and the Company will pay all Registration Expenses in connection with such request. 3. Any request for a Demand Registration shall not be otherwise deemed to be effective unless such request includes the lesser of (i) at least ten percent (10%) of the Company's outstanding Common Stock or (ii) all of the Common Stock owned by the Shareholder Party or Shareholder Parties making the request. Each request for a Demand Registration shall specify the approximate number of Registrable Securities requested to be registered and the anticipated per share price range for such offering. 4. The Medicor Parties and the ERI Parties shall each be entitled to initiate only three (3) Demand Registrations and the Belfer Parties shall be entitled to initiate only two (2) Demand Registrations to register Registrable Securities under the terms of this Section 3.1; provided, if one of such Shareholder Parties joins in the Demand Registration initiated by the other in accordance with Section 3.1(c)(5), the initiating Shareholder Party shall not be deemed to have initiated the Demand Registration for purposes (and solely for the purposes) of the limitation contained in this sentence. Notwithstanding the foregoing, if the ERI Letter or the transactions entered into as a consequence thereof constitute a "Demand Registration" under and as defined in the Shareholders Agreement (provided that solely for purposes of making such determination the registration requested in the ERI Letter shall be deemed to have satisfied the requirements for an effective "Demand Registration" set forth in Section 5.1(c)(3) of the Shareholders Agreement), then the ERI Parties shall have the right to initiate only two (2) Demand Registrations under the terms of this Section 3.1. 5. If at any time or from time to time any of the Shareholder Parties shall request registration of any Registrable Securities in accordance with this Section 3.1, the Company shall give the other Shareholder Parties prompt written notice of the proposed registration. The other Shareholder Parties shall have the right to join in such registration by giving notice to the Company within five (5) business days after such Shareholder Party receives notice of the proposed registration from the Company and the Company shall include in such registration the number of Registrable Securities requested by such other Shareholder Parties on 7 the same terms and conditions as the Registrable Securities of the Shareholder Party initiating the request. If the managing underwriter or underwriters of a proposed offering for which securities of more than one of the Shareholder Parties are included pursuant to this Section 3.1(c)(5) advise the Company in writing that in its or their good faith judgment the total amount of securities to be included in such offering exceeds the number which can be sold in such offering within a price range reasonably acceptable to the Shareholder Parties, then in such event the securities to be included in such offering shall be allocated pro rata among such Shareholder Parties and their Permitted Transferees participating in the offering based upon the number of Shares owned by each such Shareholder Party and its Permitted Transferees. 6. Any registration of Registrable Securities requested to be made on a registration statement filed on Form S-3 pursuant to Rule 415 of the Securities Act (each a "Shelf Registration Statement") shall constitute a Demand Registration and be restricted for use pursuant to a firmly underwritten offering of Common Stock. Each offering of Registrable Securities pursuant to a Shelf Registration Statement (a "Shelf Offering") shall constitute a Demand Registration (other than for purposes of Section 3.1(c)(1)) and must satisfy all requirements for a Demand Registration set forth in this Article III; provided, however, that a Shelf Offering for (i) sales of Common Stock constituting block sales of less than five percent (5%) of the Common Stock outstanding to institutional investors in solicited transactions, or (ii) sales into the market in unsolicited brokers transactions will not be required to be a firm commitment underwritten offering and will not constitute a Demand Registration if the total amount of shares registered for sale in this manner involves less than ten percent (10%) of the shares of Common Stock then outstanding. Notwithstanding the foregoing, in the event that each of the following occurs: (x) a Shareholder Party makes a Demand Registration to register shares pursuant to a Shelf Registration Statement; and (y) the Shareholder Party requesting the Shelf Registration Statement makes a Demand Registration in connection with a Shelf Offering (other than pursuant to clauses (i) or (ii) of this Section 3.1(c)(6); and (z) no other Shareholder Party exercises its rights under Section 3.2(c)(5) hereof to participate in the registration described in clause (x) or the Shelf Offering described in clause (y), then the Shelf Offering described in clause (y) shall not count as a Demand Registration for purposes of (and solely for purposes of) calculating the number of Demand Registrations available to a Shareholder Party pursuant to Section 5.2(c)(3). The foregoing sentence shall apply only with respect to the first Demand Registration for a Shelf Offering made by a Shareholder Party following a Demand Registration made by such party requesting that shares be registered pursuant to a Shelf Registration Statement, and shall not apply to any subsequent Demand Registrations by such Shareholder Party made in connection with Shelf Offerings. (d) Other Registration Rights. The Company will not grant to any Person the right to request the Company to register any equity securities of the Company with terms more 8 favorable to such Person than those granted in this Agreement without the prior written consent of the Medicor Group, ERI and the Belfer Group. (e) Priority on Over-Allotments. In the event the underwriters of any offering made pursuant to a Demand Registration exercise one or more over-allotment options with respect such offering, the shares to be included in such over-allotment option(s) will be allocated pro rata among the holders of securities participating such offering on the basis of the number of securities of each such party registered in the underlying registration to which the over-allotment option relates. Section 3.2. Piggyback Registrations. (a) Right to Piggyback. Whenever the Company proposes to register any of its equity securities under the Securities Act (other than a registration on Form S-4 or Form S-8 or any successor or similar forms and other than a Demand Registration pursuant to Section 3.1) and the registration form to be used may be used for the registration of Registrable Securities (a "Piggyback Registration"), whether or not for sale for its own account, the Company will give prompt written notice to the Medicor Group, on behalf of the Medicor Parties, ERI, on behalf of the ERI Parties, and the Belfer Group, on behalf of the Belfer Parties, of its intention to effect such a registration and will include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within twenty (20) days after the receipt of the Company's notice. The Company will use its reasonable best efforts to include, and to cause the managing underwriters, if applicable, to include in the proposed offering such Registrable Securities on the same terms and conditions as the securities of the Company included in such registration. (b) Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering within a price range reasonably acceptable to the Company, the Company will include in such registration (i) first, the securities the Company proposes to sell, to the extent of availability and, (ii) second, all other securities (including the Registrable Securities) requested to be included in such registration, pro rata among the respective holders thereof on the basis of the number of securities owned by each such holder. In the event the underwriters of such primary registration exercise one or more over-allotment options with respect thereto, the shares to be included in such over-allotment option(s) will be allocated pro rata among the Company and the holders of securities described in item (ii) of this Section 3.2(b) on the basis of the number of securities of each such party registered in underlying registration to which the over-allotment option relates. (c) Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company's securities, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering within a price range reasonably acceptable to such holders, the securities which can be included in such registration shall be allocated as follows: (i) first, the securities requested to 9 be included in such registration by the holders of the Company's securities on whose behalf the registration is being made, (ii) then, to the extent of availability, securities to be registered for the account of the Company and (iii) thereafter, to the extent of availability, to other security holders exercising piggyback registration rights, pro rata based upon the number of Shares owned by each such holder. In the event the underwriters of such secondary registration exercise one or more over-allotment options with respect thereto, the shares to be included in such over-allotment option(s) will be allocated pro rata among the holders of the Company's securities on whose behalf such secondary registration was made, the Company, and the holders of securities described in item (iii) of this Section 3.2(c) on the basis of the number of securities of each such party registered in the underlying registration to which the over-allotment option relates. (d) Limited Purpose Shelf Registration Statement. In order to facilitate the exercise by the Medicor Group, ERI and the Belfer Group of their Piggyback Registration rights, upon request of either the Medicor Group, ERI or the Belfer Group (any such request shall not constitute a Demand Registration for purposes of Section 3.1), the Company shall prepare and file with the Commission one or more registration statements on Form S-3 under Rule 415 of the Securities Act providing for the resale of Registrable Securities in an amount of shares to be mutually agreed by Company and the Medicor Group, ERI and the Belfer Group from time to time, provided, that such registration statement on Form S-3 shall be restricted for use by the holders of the securities subject to such registration statement only for participation pursuant to Section 3.2 in a firmly underwritten public offering of Common Stock proposed by the Company for the account of the Company or the account of any other security holder. Section 3.3. Holdback Agreements. (a) If requested in writing by the Company or the managing underwriters, if any, of any registration effected pursuant to Sections 3.1 or 3.2, the Medicor Group agrees not to and will cause the other Medicor Parties not to, ERI agrees not to and will cause the other ERI Parties not to, and the Belfer Group agrees not to and will cause the other Belfer Parties not to, effect any public sale or distribution (including sales pursuant to Rule 144) of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, during the time period reasonably requested by the managing underwriters, not to exceed seven (7) days prior to and the 90-day period beginning on the effective date of any underwritten Demand Registration, any underwritten Piggyback Registration or other underwritten registration by the Company of its securities (except as part of such underwritten registration). (b) If requested in writing by the managing underwriters of any registration effected pursuant to Section 3.1 or 3.2, the Company agrees (i) not to effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the time period reasonably requested by the managing underwriters, not to exceed seven days prior to and during the 90-day period beginning on the effective date of any underwritten Demand Registration or any underwritten Piggyback Registration (except as part of such underwritten registration or pursuant to registrations on Form S-4 or Form S-8 or any successor forms), and (ii) to cause each holder of its Common Stock, or any securities convertible into or exchangeable or exercisable for Common Stock, purchased 10 from the Company at any time after the date of this Agreement (other than in a registered public offering), to so agree. (c) If the Company has previously filed a registration statement with respect to Registrable Securities pursuant to Sections 3.1 or 3.2 hereof or pursuant to Sections 5.1 or 5.2 of the Shareholders Agreement, and if such previous registration has not been withdrawn or abandoned, the Company will not file or cause to be effected any other registration of any of its equity securities or securities convertible or exchangeable into or exercisable for its equity securities under the Securities Act (except on Form S-4 or Form S-8 or any successor forms), whether on its own behalf or at the request of any holder or holders of such securities, until a period of at least ninety (90) days has elapsed from the effective date of such previous registration. Section 3.4. Registration Procedures. Whenever the Medicor Group, on behalf of the Medicor Parties, ERI, on behalf of the ERI Parties, or the Belfer Group on behalf of the Belfer Parties has requested that any Registrable Securities be registered pursuant to this Agreement, the Company will use its best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company will as expeditiously as possible: (a) prepare and file with the Commission a registration statement with respect to such Registrable Securities and thereafter use its reasonable best efforts to cause such registration statement to become effective (provided that, before filing a registration statement or prospectus or any amendments or supplements thereto, the Company will furnish to the counsel selected by the holders of the Registrable Securities covered by such registration statement copies of all such documents proposed to be filed, which documents will be subject to reasonable review of such counsel); (b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of either (i) not less than six months (subject to extension pursuant to Section 3.7(b)) or, if such registration statement relates to an underwritten offering, such longer period as in the opinion of counsel for the underwriters a prospectus is required by law to be delivered in connection with sales of Registrable Securities by an underwriter or dealer or (ii) such shorter period as will terminate when all of the securities covered by such registration statement have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration statement (but in any event not before the expiration of any longer period required under the Securities Act), and to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement until such time as all of such securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration statement; (c) furnish to each seller of Registrable Securities such number of copies of such registration statement, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as 11 such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller; (d) use its best efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph, (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction);

(k) in the event of the issuance of any stop order, injunction or other order or requirement suspending the effectiveness of a registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any securities included in such registration statement for sale in any jurisdiction, the Company will use its reasonable best efforts promptly to obtain the withdrawal of such order and to notify the holders of all of the Registrable Securities covered by the registration statement of such order; (l) obtain a cold comfort letter, dated the effective date of such registration statement (and, if such registration includes an underwritten public offering, dated the date of the closing under the underwriting agreement), signed by the Company's independent public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the holders of a majority of the Registrable Securities being sold reasonably request (provided that such Registrable Securities constitute at least 10% of the securities covered by such registration statement); (m) provide a legal opinion of the Company's outside counsel, dated the effective date of such registration statement (and, if such registration includes an underwritten public offering, dated the date of the closing under the underwriting agreement), with respect to the registration statement, each amendment and supplement thereto, the prospectus included herein (including the preliminary prospectus) and such other documents relating thereto in customary form and covering such matters of the type customarily covered by legal opinions of such nature;

Registration Expenses. (a) The Company shall pay all Registration Expenses relating to any registration of Registrable Securities hereunder. "Registration Expenses" shall mean any and all fees and expenses incident to the Company's performance of or compliance with this Article III, including, without limitation: (i) Commission, stock exchange or National Association of Securities Dealers, Inc. registration and filing fees and all listing fees and fees with respect to the inclusion of securities on the Nasdaq National Market, (ii) fees and expenses of compliance with state securities or "blue sky" laws and in connection with the preparation of a "blue sky" survey, including, without limitation, reasonable fees and expenses of blue sky counsel, (iii) printing expenses, (iv) messenger and delivery expenses, (v) fees and disbursements of counsel for the Company, (vi) with respect to each registration, reasonable fees and disbursements of one counsel for the selling holders of Shares (selected by the holders making the Demand Registration request, in the case of a registration pursuant to Section 3.1, and selected by the holders of a majority of the Registrable Securities included in such registration, in the case of a registration pursuant to Section 3.2) as well as of one local counsel, (vii) fees and disbursements of all independent public accountants (including the expenses of any audit and/or "cold comfort" letter) and fees and expenses of other persons, including special experts, retained by the Company, and (viii) any other fees and disbursements of underwriters, if any, customarily paid by issuers or sellers of securities. (b) Notwithstanding the foregoing, (i) the provisions of this Section 3.5 shall be deemed amended to the extent necessary to cause these expense provisions to comply with "blue sky" laws of each state in which the offering is made and (ii) in connection with any registration hereunder, each holder of Registrable Securities being registered shall pay all underwriting discounts and commissions and transfer taxes, if any, attributable to the Registrable Securities included in the offering by such holder. Section 3.6. Indemnification. (a) The Company agrees to indemnify and hold harmless, to the extent permitted by law, each holder of Registrable Securities, its officers and Directors and each Person who controls such holder (within the meaning of the Securities Act) against any losses, claims, damages, liabilities, joint or several, to which such holder or any such Director or officer or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained (A) in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or (B) in any application or other document or communication (in this Section 3.6 collectively called an "application") executed by or on behalf of the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify any securities covered by such registration statement under the "blue sky" or securities laws thereof, or (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company will reimburse such holder and each such Director, officer and controlling person for any legal or any other expenses incurred by them in connection with 14 investigating or defending any such loss, claim, liability, action or proceeding; provided that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission, made in such registration statement, any such prospectus or preliminary prospectus or any amendment or supplement thereto, or in any application, in reliance upon and in conformity with written information prepared and furnished to the Company by such holder expressly for use therein or by such holder's failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such holder with a sufficient number of copies of the same. In connection with an underwritten offering, the Company will indemnify such underwriters, their officers and Directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the holders of Registrable Securities. (b) In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder will furnish to the Company in writing such information and documents as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, will indemnify and hold harmless the Company, its Directors and officers and each other Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities, joint or several, to which the Company or any such Director or officer or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or in any application or (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is made in such registration statement, any such prospectus or preliminary prospectus or any amendment or supplement thereto, or in any application, in reliance upon and in conformity with written information prepared and furnished to the Company by such holder expressly for use therein, and such holder will reimburse the Company and each such Director, officer and controlling person for any legal or any other expenses incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided that the obligation to indemnify will be individual to each holder and will be limited to the net amount of proceeds received by such holder from the sale of Registrable Securities pursuant to such registration statement. (c) Any Person entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled 15 to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. (d) The indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, Director or controlling Person of such indemnified party and will survive the transfer of securities by any holder thereof. The Company also agrees to make such provisions, as are reasonably requested by any indemnified party, for contribution to such party in the event the Company's indemnification is unavailable for any reason. Section 3.7. Participation in Underwritten Registrations. (a) If requested by the underwriters for any underwritten offering pursuant to a Demand Registration requested under Section 3.1, the Company shall enter into a customary underwriting agreement with the underwriters. Such underwriting agreement shall be satisfactory in form and substance to the Person who requested such registration and shall contain such representations and warranties by, and such other agreements on the part of, the Company and such other terms as are generally prevailing in agreements of that type, including, without limitation, indemnities and contribution agreements. Such underwriting agreement shall also contain such representations, warranties, indemnities and contributions by the participating holders as are customary in agreements of that type. In the case of a registration pursuant to Section 3.2 hereof, if the Company shall have determined to enter into any underwriting agreements in connection therewith, all of the holders' Registrable Securities to be included in such registration shall be subject to such underwriting agreement. Such underwriting agreement shall also contain such representations, warranties, indemnities and contributions by the participating holders as are customary in agreements of that type. (b) Each Person that is participating in any registration hereunder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3.4(e) above, such Person will forthwith discontinue the disposition of its Registrable Securities pursuant to the registration statement until such Person's receipt of the copies of a supplemented or amended prospectus as contemplated by such Section 3.4(e). In the event the Company shall give any such notice, the applicable time period mentioned in Section 3.4(b) during which a registration statement is to remain effective shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to this paragraph to and including the date when each seller of a Registrable Security covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by Section 3.4(e). Section 3.8. Current Public Information. At all times after the Company has filed a registration statement with the Commission pursuant to the requirements of either the Securities Act or the Exchange Act, the Company will file all reports required to be filed by it under the Act and the Exchange Act and the rules and regulations adopted by the Commission thereunder, and 16 will take such further action as any holder or holders of Registrable Securities may reasonably request, all to the extent required to enable such holders to sell Registrable Securities pursuant to Rule 144. Section 3.9. Cooperation. If the Company determines to authorize and/or issue any capital stock or other debt or equity securities in a public offering, each of the Shareholder Parties and their Permitted Transferees agrees to cooperate with the Company and to take all action necessary to assist the Company in consummating such transaction.
