Section 7. CERTAIN ADJUSTMENTS OF EXERCISE PRICE. 7.1 ADJUSTMENT OF EXERCISE PRICE. The number, class and Exercise Price of securities for which this Warrant may be exercised are subject to adjustment from time to time upon the happening of certain events as hereinafter provided: 7.1.1 RECAPITALIZATION. If the outstanding shares of the Company's Common Stock are divided into a greater number of shares or the Company issues a stock dividend on its outstanding Common Stock, the number of shares of Common Stock purchasable upon the exercise of this Warrant shall be proportionately increased and the Exercise Price shall be proportionately reduced and, conversely, if the outstanding shares of Common Stock are combined into a smaller number of shares of Common Stock, the number of shares of Common Stock purchasable upon the exercise of this Warrant shall be proportionately reduced and the Exercise Price shall be proportionately increased. The increases and reductions provided for in this Section 7.1.1 shall be made with the intent and, as nearly as practicable, the effect that neither the percentage of the total equity of the Company obtainable on exercise of this Warrant nor the price payable for such percentage shall be affected by any event described in this Section 7.1.1. 7.1.2 MERGER OR REORGANIZATION, ETC. In the event of any change in the Common Stock through merger, consolidation, reclassification, reorganization, partial or complete liquidation or other change in the capital structure of the Company (not including the issuance of additional shares of capital stock other than by stock dividend or stock split), then, as a condition of such change in the capital structure of the Company, appropriate and adequate - 5 - provision shall be made so that the Warrant Holder of this Warrant will have the right thereafter to receive upon the exercise of this Warrant the kind and amount of shares of stock or other securities or property to which it would have been entitled if immediately prior to such merger, consolidation, reclassification, reorganization, recapitalization or other change in the capital structure, it had held the number of shares of Common Stock then obtainable upon the exercise of this Warrant. In any such case appropriate adjustment shall be made in the applications of the provisions set forth herein with respect to the rights and interest thereafter of the Warrant Holder, to the end that the provisions set forth herein shall thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property thereafter deliverable upon the exercise of this Warrant. 7.2 NOTICE OF ADJUSTMENT. Whenever an event occurs requiring any adjustment to be made pursuant to Section 7.1, the Company shall promptly file with its Secretary or an Assistant Secretary at its principal office and with its stock transfer agent, if any, a certificate of its chief executive officer specifying such adjustment, setting forth in reasonable detail the acts requiring such adjustment, and stating such other facts as shall be necessary to show the manner and figures used to compute such adjustment. Such chief executive officer's certificate shall be made available at all reasonable times for inspection by the Warrant Holder. Promptly (but in no event more than 30 days) after each such adjustment, the Company shall give a copy of such certificate by certified mail to the Warrant Holder. Section 8. SUBDIVISION OF WARRANT. At the request of the Warrant Holder in connection with a transfer of a portion of this Warrant upon surrender of this Warrant for such purpose to the Company at its principal office, the Company at its expense (except for any transfer tax payable) will issue and exchange therefor new Warrants of like tenor and date representing in the aggregate the amount of the Warrant Shares. Section 9. REGISTRATION RIGHTS. 9.1 DEFINITIONS. For purposes of this Section 9: (a) The term "register", "registered" and "registration" refer to a registration effected by preparing and filing a registration statement or similar document in compliance with the Securities Act, and the declaration or ordering of effectiveness of such registration statement or document; (b) The term "Registrable Securities" means any Common Stock issued or issuable upon exercise of this Warrant, excluding, however, any Registrable Securities sold by a person in a transaction in which his rights are not assigned under Section 9.6 hereof. (c) The number of shares of "Registrable Securities then outstanding" shall be determined by the number of shares of Common Stock outstanding which are, and the number of shares of Common Stock issuable pursuant to then exercisable or convertible securities which are, Registrable Securities; and - 6 - (d) The term "Holder" means any person owning or having the right to acquire Registrable Securities or any assignee thereof in accordance with Section 9.10 hereof. 9.2 COMPANY REGISTRATION. (a) If the Company proposes to register (including for this purpose a registration effected by the Company for shareholders other than the Holders) any of its capital stock or other securities under the Securities Act in connection with the public offering of such stock or securities solely for cash (other than a registration on any form which does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities), the Company shall, each such time, promptly give each Holder written notice of such registration together with a list of the jurisdictions in which the Company intends to attempt to qualify such securities under the applicable blue sky or other state securities laws. Upon the written request of each Holder given within twenty (20) days after giving of such written notice by the Company in accordance with Section 11.2, the Company shall, subject to the limitations set forth in subsection 9.2(b) below, cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered. (b) The right of any Holder to registration pursuant to this Section 9.2 shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for underwriting by the Company. Notwithstanding any other provision of this Section 9.2, if the underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, and: (i) if such registration is the first registered offering of the sale of the Company's securities to the public, then the underwriter may (subject to the allocation priority set forth below) exclude some or all Registrable Securities from such registration and underwriting; or (ii) if such registration is other than the first registered offering of the sale of the Company's securities to the general public, then the underwriter may (subject to the allocation priority set forth below) limit the number of Registrable Securities to be included in the registration and underwriting to not less than twenty-five percent (25%) of the number of securities included therein. In the event of such a limitation, the Company shall so advise all Holders requesting registration, and the number of shares of securities that may be included in the registration and underwriting shall be allocated in the following manner: The securities of the Company held by officers and directors of the Company (other than Registrable Securities and other than securities held by persons who, by virtue of contracts with the Company, are entitled to include their securities in such registration) shall be excluded from such registration and underwriting to the extent required by such limitation, and, if a further limitation of the number of shares is required, the number of shares that may be included in the - 7 - registration and underwriting shall be allocated among all other holders (including Holders of Registrable Securities) thereof in proportion, as nearly as practicable, to the respective amounts of securities (including Registrable Securities) which would otherwise be entitled to inclusion in such registration held by such Holders or holders at the time of filing the registration statement. If any Holder disapproves of the terms of any such underwriting, he may elect to withdraw therefrom by written notice to the Company and the underwriter. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration. (c) The Company's obligations under this Section 9.2 shall terminate with respect to any Holder one year after the Expiration Date. 9.3 EXPENSES OF REGISTRATION. (a) As used in this Section 9.3, "Registration Expenses" shall mean all expenses incurred by the Company in complying with Section 9.2, hereof, including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel for the Company, fees and disbursements of a single counsel for all Holders, blue sky fees and expenses, and the expense of any special audits incident to or required by any such registration (but excluding the compensation of regular employees of the Company which would be paid in any event by the Company); and "Selling Expenses" shall mean all underwriting discounts and selling commissions applicable to the sale. (b) All Registration Expenses incurred in connection with any registration, qualification or compliance pursuant to this Section 9 shall be borne by the Company; and all Selling Expenses shall be borne by the Holders of the securities so registered pro rata on the basis of the number of shares so registered and sold. 9.4 DELAY OF REGISTRATION. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 9. 9.5 INDEMNIFICATION. In the event any Registrable Securities are included in a registration statement under this Section 9: (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the officers, directors and agents of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the 1934 Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the 1934 Act or other federal or state law or common law doctrine related to fraud, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a - 8 - "Violation"): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the 1934 Act, any state securities law or any rule or regulation promulgated under the Securities Act, the 1934 Act or any state securities law; and the Company will pay as incurred any legal or other expenses reasonably incurred by each such Holder, officer, director, agent, underwriter, or controlling person in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this subsection 9.8(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, officer, director, agent, underwriter or controlling person; provided further, however, that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement, alleged untrue statement, omission, or alleged omission made in a preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time the registration statement becomes effective, or in the amended prospectus filed with the SEC pursuant to Rule 424(b) (the "Final Prospectus"), such indemnity agreement shall not inure to the benefit of any underwriter, or any Holder or any party otherwise entitled to indemnification hereunder (if there is no underwriter), if a copy of the Final Prospectus was not furnished to the person or entity asserting the loss, liability, claim, or damage at or prior to the time such action is required by the Securities Act. (b) Promptly after receipt by an indemnified party under this Section 9.5 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 9.5, notify the indemnifying party in writing of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if the indemnifying party shall not have engaged counsel within a reasonable period of time to assure the defense of such action, or if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to notify an indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party - 9 - under this Section 9.5, but the omission so to notify the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 9.5. 9.6 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the Company to register Registrable Securities pursuant to this Section 9 may be assigned by a Holder to: (a) any entity which is controlling, controlled by or under common control with any Warrant Holder, any member of Warrant Holder's immediate family (being limited to spouses and lineal ancestors and descendants) or any partnership composed of, or trust for the primary benefit of, the Warrant Holder or members of such Warrant Holder's immediate family; (b) a general or limited partner of the Warrant Holder; or (c) any other transferee or assignee of such securities upon the transfer or assignment of securities representing at least twenty-five percent (25%) of the total number of shares of Warrant Shares purchased by the Warrant Holder pursuant to this Warrant; provided that the Company is, within a reasonable time after any such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned and an Assumption Agreement in the form attached as EXHIBIT A to this Warrant executed by the party receiving the assignment of registration rights pursuant to this Section 9; and provided, further, that such assignment shall be effective only if immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Securities Act. 9.7 "MARKET STAND-OFF AGREEMENT". The Warrant Holder hereby agrees that it shall not, to the extent requested by the Company and any underwriter of securities of the Company in a registered offering in which such Warrant Holder had a right to sell Registrable Securities hereunder, sell or otherwise transfer or dispose of any Registrable Securities during the one hundred eighty (180) day period following the effective date of such registration statement; PROVIDED, however, that: (a) Such agreement shall be applicable only to the first such registration statement of the Company which covers shares (or securities) to be sold on its behalf to the public in an underwritten offering; and (b) Such agreement is conditioned upon all employees, officers and directors of the Company and all other persons with contractual registration rights (whether or not pursuant to this Warrant) entering into similar agreements. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registrable Securities of the Warrant Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of such ninety (90) day period. 9.8 MODIFICATION OF RIGHTS. Any of the terms and provisions of this Section 9 shall be subject to modification from time to time upon written agreement between at least fifty-one percent (51%) in interest of the Holders and the Company.
