Without limiting the generality of the foregoing, the Company (a) will not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the amount payable therefor upon such exercise; (b) will take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of all warrants, including this Warrant, from time to time outstanding; and (c) will not transfer all or substantially all of its properties and assets to any other Person (corporate or otherwise), or consolidate with or merge into any other Person or permit any such person to consolidate with or merge into the Company, unless such other Person shall expressly assume in writing and will be bound by all of the terms of this Warrant. 8. FRACTIONAL SHARES. No fractional shares or scrip representing fractional shares of Common Stock shall be issued in connection with the exercise of this Warrant, but the Company shall pay, in lieu of 4 any fractional share, a cash payment on the basis of the Fair Value Per Share of the Common Stock to be acquired pursuant to such exercise for such fractional share. 9. REGISTRATION RIGHTS. (a) If at any time during the term of the Exercise Period of this Warrant the Company shall propose to file a registration statement pursuant to the Securities Act of 1933, as amended (the "Act"), for the purpose of registering shares of the Company's Common Stock to be sold for cash, not less than thirty (30) days prior to the proposed filing date of such registration statement the Company shall give notice in writing to Holder of its intent to file the proposed registration statement and the number of shares of Common Stock it intends to register. Holder shall have the right to request in writing within twenty (20) days of the receipt thereby of such notice that the Company include in such registration any of the Warrant Securities that Holder may have acquired pursuant to exercise of this Warrant. If the total amount of securities, including Warrant Securities, requested to be included in an offering by the holders of any class of outstanding securities of the Company exceeds the amount of securities that any managing underwriter or the Company reasonably and in writing determines to be compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Warrant Securities, which the managing underwriter or the Company reasonably determines will not jeopardize the success of the offering (the securities so included to be apportioned pro rata among the selling shareholders according to the total amount of securities entitled to be included therein owned by each selling shareholder or in such other proportions as shall mutually be agreed to by such selling shareholders). Holder agrees that in the event that Holder's Warrant Securities are to be included in the registration statement, Holder will cooperate with the Company in the preparation and filing of any such registration statement. All expenses, disbursements and fees, except fees of any counsel hired by Holder, incurred in connection with the registration by the Company of any shares of Warrant Securities for any such Person under this PARAGRAPH 9(a) shall be borne by the Company. (b) In the event of the preparation and filing of a registration statement as provided in this PARAGRAPH 9, the Company's obligations to use its best efforts to effect the registration of shares for Holder shall include such qualification under applicable blue sky or other state securities laws as may be requested by Holder. (c) In connection with any registration under the Act pursuant to this Agreement: (i) the Company will furnish Holder with a copy of the registration statement and all amendments thereto and will supply Holder with copies of any prospectus included therein (and, if necessary, with copies of a prospectus meeting the requirements of Section 10(a)(3) of the Act; PROVIDED, HOWEVER, that no such prospectus need be supplied more than nine (9) months after the effective date of such registration statement) in such quantities as may be necessary for the purposes of such proposed sale or distribution; and (ii) each Holder will be required to enter into an underwriting agreement, in usual and customary form, with the underwriters of such offering. (d) Nothing in this PARAGRAPH 9 shall be deemed to (i) require the Company to proceed with any registration of its securities after giving the notice herein provided; or (ii) provide Holder with any right to participate in the selection of the managing underwriter(s) for such offering. 10. RESTRICTIONS ON TRANSFER. Holder represents and warrants that this Warrant is being purchased for Holder's investment account without a view towards the resale or distribution thereof in violation of applicable securities laws. It is understood that in case of subsequent sale of such Warrant 5 under certain circumstances, such sale might be deemed to constitute a public distribution within the meaning of, and require registration under, the provisions of the Act. (a) Holder agrees that prior to making any disposition of this Warrant, Holder will give written notice to the Company describing briefly the manner of any such proposed disposition and will not make any such disposition until the Company has notified Holder in writing that the Company has consented to the disposition, AND (i) Holder has furnished the Company with an opinion of counsel satisfactory to the Company addressed to Holder and the Company to the effect that the proposed transfer, sale or assignment is exempt from registration under the Act and state securities laws, or (ii) a registration statement covering the Warrant Securities issuable under this Warrant has been filed by the Company and declared effective by the Commission. (b) Holder acknowledges and agrees that unless the Warrant Securities are registered under the Act, such Warrant Securities shall be "restricted securities" for purposes of Rule 144 under the Act. Holder shall, prior to any transfer or disposition or attempted transfer or disposition of such Warrant Securities give written notice to the Company of Holder's intention to effect such transfer or disposition and shall deliver to the Company an opinion of legal counsel (reasonably suitable to the Company) that the proposed transfer or disposition of the Warrant Securities may be effected without registration thereof under the Act and without taking any similar action under any other applicable securities laws, in which case Holder shall be entitled to transfer or dispose of the Warrant Securities in accordance with the terms of the notice delivered by such Holder to the Company. Until such Warrant Securities are registered under the Act pursuant to Paragraph 9 hereof, each certificate evidencing the Warrant Securities so transferred or disposed of (and each certificate evidencing any untransferred Warrant Securities) shall bear the following restrictive legend unless in the opinion of Company counsel such legend is not required: "The shares represented by this certificate have not been registered under the Securities Act of 1933 (the "Act") or any state securities laws. These shares may not be offered for sale, sold or otherwise transferred except pursuant to an effective registration statement under the Act or pursuant to an exemption from such registration." (c) Until this Warrant is transferred on the books of the Company, the Company may treat the registered holder thereof as the absolute owner thereof for all purposes, notwithstanding any notice to the contrary. (d) In connection with any registration of shares of stock, pursuant to this PARAGRAPH 10, Holder shall furnish the Company with such information concerning it and the proposed sale or distribution as shall, in the opinion of counsel for the Company, be required for use in the preparation of a registration statement. 11. INDEMNIFICATION. (a) If Holder shall acquire Warrant Securities (in such event, being hereinafter referred to as the "Distributing Holder"), the Company will indemnify and hold harmless the Distributing Holder and each Person, if any, who controls the Distributing Holder within the meaning of the Act against any losses, claims, damages, liabilities or actions, joint or several (including all costs of defense and investigation and all attorneys' fees), to which the Distributing Holder or such controlling Person may become subject, under the Act or otherwise, insofar as such losses, claims, damages, liabilities or actions (i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained, on the effective date thereof, in any registration 6 statement referred to in PARAGRAPH 9 hereof and under which such shares of stock were registered under the Act, and in any preliminary prospectus or final prospectus contained therein, or in any amendment or supplement thereto, or (ii) arise out of or are based upon the omission or alleged omission to state in any such document a material fact required to be stated therein or necessary to make the statements in any such document not misleading; and will reimburse the Distributing Holder and each such controlling Person for any legal or other expenses reasonably incurred by the Distributing Holder or such controlling Person in connection with investigating or defending any such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or omission made in said registration statement, preliminary prospectus, final prospectus or amendment or supplement to any of the foregoing in reliance upon and in conformity with written information furnished by the Distributing Holder and/or controlling Person for use in the preparation thereof. (b) The Distributing Holder will indemnify and hold harmless the Company, each of its directors, each of its officers who signed said registration statement and each Person, if any, who controls the Company within the meaning of the Act, against any losses, claims, damages, liabilities or actions (including all costs of defense and investigation and all attorneys' fees), to which the Company or any such director, officer or controlling Person may become subject, under the Act or otherwise, insofar as such losses, claims, damages, liabilities or actions (i) arise out of or are based upon any untrue or alleged untrue statement of any material fact contained, on the effective date thereof, in any registration statement referred to in PARAGRAPH 9 hereof and under which such shares of stock were registered under the Act, and in any preliminary prospectus or final prospectus contained therein, or in any amendment or supplement thereto, or (ii) arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; and will reimburse the Company or any such director, officer or controlling Person for any legal or other expenses reasonably incurred thereby in connection with investigating or defending any such loss, claim, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in said registration statement, preliminary prospectus, final prospectus or amendment or supplement to any of the foregoing in reliance upon and in conformity with written information furnished by the Distributing Holder and/or controlling Person for use in the preparation thereof. (c) Promptly after receipt by an indemnified party under this PARAGRAPH 11 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this PARAGRAPH 11, notify the indemnifying party of the commencement thereof, but the failure so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this PARAGRAPH 11. (d) In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate in, and to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party; and after notice from the indemnifying party to the indemnified party that it will assume the defense thereof, with counsel satisfactory to the indemnified party, the indemnifying party will not be liable to such indemnified party under this PARAGRAPH 11 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof. The indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall not be at the expense of the indemnifying party if the indemnifying party has assumed the defense of the action with counsel reasonably 7 satisfactory to the indemnified party; PROVIDED, HOWEVER, that the fees and expenses of the indemnified party's counsel shall be at the expense of the indemnifying party if (i) the employment of such counsel has been specifically authorized in writing by the indemnifying party or (ii) the named parties to such action (including any impleaded parties) include both the indemnified party and the indemnifying party and such indemnified party shall have been advised by counsel that there may be one or more legal defenses available to such indemnified party that are not available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party, it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys for the indemnified party, which firm shall be designated in writing by the indemnified party). The indemnifying party shall not be liable for any settlement of any such action or proceeding effected without its written consent, but if settled with its written consent, or if there be a final judgment for the plaintiff in any such action or proceeding, the indemnifying party agrees to indemnify and hold harmless the indemnified party from and against any loss or liability by reason of such settlement or judgment. 12. RESERVATION OF STOCK ISSUABLE UPON EXERCISE. The Company will at all times reserve and keep available, solely for issuance and delivery upon the exercise of this Warrant, such number of its shares of Common Stock or other securities as shall from time to time be sufficient to effect the exercise of this Warrant. If at any time the number of authorized but unissued shares of Common Stock or other securities shall not be sufficient for such purposes, the Company will take such corporate actions as may, in the opinion of its counsel, be necessary to increase the Company's authorized but unissued shares of Common Stock or other securities to such number of shares as shall be sufficient for such purpose. 13. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents and warrants to Holder that (a) it has all requisite corporate power and authority, and has taken all necessary corporate action, to issue and deliver this Warrant, to authorize and reserve for issuance and, upon payment from time to time of the Exercise Price, to issue and deliver the Warrant Securities issuable upon the exercise of this Warrant; (b) the Warrant Securities to be delivered upon exercise of this Warrant, when payment is made therefor in accordance with the terms of this Warrant, will be validly issued, fully paid and nonassessable; (c) the holder of this Warrant shall receive good and marketable title to the Warrant Securities, free and clear of all voting and other trust arrangements, liens, encumbrances, equities and claims whatsoever not created by Holder, and it shall have paid all taxes, if any, in respect to the issuance thereof; and (d) the execution and delivery of this Warrant and the consummation of the transactions herein contemplated will not result in a breach or violation of, or constitute a default or an event permitting acceleration under, any statute, its Articles of Incorporation or bylaws, or any mortgage, lease, indenture or any other agreement, instrument, decree, order, judgment, rule or regulation to which it is subject or a party. 14. REPLACEMENT OF WARRANT. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction, upon delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Company will execute and deliver at its expense, in lieu thereof, a new warrant of like tenor to Holder. 15. SPECIFIC PERFORMANCE. The Company stipulates that the remedies at law available to the holder of this Warrant in the event of any default or threatened default by it in the performance of or compliance with any of the terms of the Agreement are not and will not be adequate, and that such terms may be specifically enforced by a decree for the specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise. 8 16. APPLICABLE LAW. THIS WARRANT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS, WITHOUT GIVING EFFECT TO PRINCIPLES OF CHOICE OF LAWS OF SUCH STATE. 17. ENTIRE AGREEMENT. This Warrant constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes any and all prior agreements and understandings relating to the subject matter hereof. This Warrant and any of the terms hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of such change, waiver, discharge or termination is sought. 18. SUCCESSORS AND ASSIGNS. This Warrant shall be binding upon and inure to the benefit of the Company and Holder and their respective successors and permitted assigns; provided, however, nothing herein shall be construed to permit assignment of the Warrant except in accordance with the provisions herein. 19. SEVERABILITY. Every provision of this Warrant is intended to be severable. If any term or provision hereof (or portion thereof) is determined to be illegal or unenforceable for any reason whatsoever, such illegality or unenforceability shall not affect any other term or provision (or portion thereof) of this Warrant. 20.
