("NTB"), as representative (the "Representative") of the several underwriters listed on Schedule 1 annexed hereto (the "Underwriters"), as set forth below. The Company proposes to issue and sell to the Underwriters _________ shares of the Company's $.001 par value common stock (the "Common Stock"). The shares of Common Stock being sold by the Company are referred to as the "Firm Shares." In addition, for the sole purpose of covering over-allotments from the sale of the Firm Shares the Company proposes to grant to the Underwriters an option to purchase an additional ______ shares of Common Stock (the "Firm Option Shares" or the "Option Shares"), all as provided in Section 2(c) of this agreement (the "Agreement") and to issue to you the Representative's Warrant (as defined in Section 2 hereof) to purchase certain further additional shares of Common Stock. The Firm Shares and the Option Shares are collectively referred to herein as either the "Shares" or the "Securities." 1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents and warrants to, and agrees with, the Underwriter that: (a) A registration statement on Form SB-2 (File No. 333-_____), with respect to the Securities and the Representative's Warrant Securities (as hereinafter defined), including a prospectus subject to completion, has been filed by the Company with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Act "), and one or more amendments to that registration statement may have been so filed. Copies of such registration statement and of each amendment heretofore filed by the Company with the Commission have been delivered to the Underwriters. After the execution of this Agreement, the Company will file with the Commission either (i) if the registration statement, as it may have been amended, has been declared by the Commission to be effective under the Act, a prospectus in the form most recently included in that registration statement (or, if an amendment thereto shall have been filed, in such amendment), with such changes or insertions as are required by Rule 430A under the Act or permitted by Rule 424(b) under the Act and as have been provided to and approved by the Underwriters prior to the execution of this Agreement, or (ii) if that registration statement, as it may have been amended, has not been declared by the Commission to be effective under the Act, an amendment to that registration statement, including a form of prospectus, a copy of which amendment has been furnished to and approved by the Underwriters prior to the execution of this Agreement. The Company also may file a related registration statement with the Commission pursuant to Rule 462(b) under the Act for purposes of registering certain additional Securities, which registration statement shall become effective upon filing with the Commission (the "Rule 462(b) Registration Statement"). As used in this Agreement, the term "Registration Statement" means that registration statement, as amended at the time it was or is declared effective, and any amendment thereto that was or is thereafter declared effective, including all financial schedules and exhibits thereto and any information omitted therefrom pursuant to Rule 430A under the Act and included in the Prospectus (as hereinafter defined), together with any Rule 462(b) Registration Statement; the term "Preliminary Prospectus" means each prospectus subject to completion filed with the Registration Statement (including the prospectus subject to completion, if any, included in the Registration Statement at the time it was or is declared effective); and the term "Prospectus" means the prospectus first filed with the Commission pursuant to Rule 424(b) under the Act or, if no prospectus is so filed pursuant to Rule 424(b), the prospectus included in the Registration Statement. The Company has caused to be delivered to the Underwriters copies of each Preliminary Prospectus and has consented to the use of those copies for the purposes permitted by the Act. If the Company has elected to rely on Rule 462(b) and the Rule 462(b) Registration Statement has not been declared effective, then (i) the Company has filed a Rule 462(b) Registration Statement in compliance with and that is effective upon filing pursuant to Rule 462(b) and has received confirmation of its receipt and (ii) the Company has given irrevocable instructions for transmission of the applicable filing fee in connection with the filing of the Rule 462(b) Registration Statement, in compliance with Rule 111 promulgated under the Act or the Commission has received payment of such filing fee. (b) The Commission has not issued any order preventing or suspending the use of any Preliminary Prospectus. When each Preliminary Prospectus and each amendment and each supplement thereto was filed with the Commission it (i) contained all statements required to be stated therein, in accordance with, and complied with the requirements of, the Act and the rules and regulations of the Commission thereunder and (ii) did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. When the Registration Statement was or is declared effective, it (i) contained or will contain all statements required to be stated therein in accordance with, and complied or will comply with the requirements of, the Act and the rules and regulations of the Commission thereunder and (ii) did not or will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading. When the Prospectus and each amendment or supplement thereto is filed with the Commission pursuant to Rule 424(b) (or, if the Prospectus or such amendment or supplement is not required so to be filed, when the Registration Statement containing such Prospectus or amendment 2 or supplement thereto was or is declared effective) and on the Firm Closing Date and any Option Closing Date (as each such term is hereinafter defined), the Prospectus, as amended or supplemented at any such time, (i) contained or will contain all statements required to be stated therein in accordance with, and complied or will comply with the requirements of, the Act and the rules and regulations of the Commission thereunder and (ii) did not or will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The foregoing provisions of this paragraph (b) do not apply to statements or omissions made in any Preliminary Prospectus, the Registration Statement or the Prospectus or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by the Underwriters specifically for use therein. (c) The Company is duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation, and is duly qualified or authorized to transact business as a foreign corporation and is in good standing in each jurisdiction where the ownership or leasing of its properties or the conduct of its businesses require such qualification or authorization. The Company has no subsidiaries. (d) The Company has full corporate power and authority, and all necessary material authorizations, approvals, orders, licenses, certificates and permits of and from all governmental regulatory authorities, to own or lease its property and conduct its business as now being conducted and as proposed to be conducted as described in the Registration Statement and the Prospectus (and, if the Prospectus is not in existence, the most recent Preliminary Prospectus).

There are no outstanding options, warrants or other rights granted by the Company to purchase shares of its Common Stock or other securities, other than as described in the Prospectus (and, if the Prospectus is not in existence, the most recent Preliminary Prospectus).

The issuance, offering and sale by the Company to the Underwriters of the Securities pursuant to this Agreement or the Representative's Securities pursuant to the Representative's Warrant Agreement, the compliance by the Company with the provisions of this Agreement and the Representative's Warrant Agreement, and the consummation of the other transactions contemplated by this Agreement and the Representative's Warrant Agreement do not (i) require the consent, approval, authorization, registration or qualification of or with any court or governmental or regulatory authority, except such as have been obtained or may be required under state securities or blue sky laws and, if the Registration Statement filed with respect to the Securities (as amended) is not effective under the Act as of the time of execution hereof, such as may be required (and shall be obtained as provided in this Agreement) under the Act, or (ii) conflict with or result in a breach or violation of, or constitute a default under, any material contract, indenture, mortgage, deed of trust, loan agreement, note, lease or other material agreement or instrument to which the Company is a party or by which the Company or any of its property is bound or subject, or the certificate of incorporation or by-laws of the Company, or any statute or any rule, regulation, judgment, decree or order of any court or other governmental or regulatory authority or any arbitrator applicable to the Company.

(p) The Company possesses adequate licenses, orders, authorizations, approvals, certificates or permits issued by the appropriate federal, state or foreign regulatory agencies or bodies necessary to conduct its business as described in the Registration Statement and the Prospectus (and, if the Prospectus is not in existence, the most recent Preliminary Prospectus), and, except as disclosed in the Prospectus (and, if the Prospectus is not in existence, the most recent Preliminary Prospectus), there are no pending or, to the best knowledge of the Company, threatened, proceedings relating to the revocation or modification of any such license, order, authorization, approval, certificate or permit.

(u) The Company is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which it is engaged; the Company has not been refused any insurance coverage sought or applied for; and the Company has no reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not materially and adversely affect the condition (financial or otherwise), business, prospects, net worth or results of operations of the Company, except as described in or contemplated by the Prospectus (and, if the Prospectus is not in existence, the most recent Preliminary Prospectus).

PURCHASE, SALE AND DELIVERY OF THE SECURITIES AND THE REPRESENTATIVE'S WARRANTS. (a) On the basis of the representations, warranties, agreements and covenants herein contained and subject to the terms and conditions herein set forth, the Company agrees to issue and sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company, the number of Firm Shares as set forth opposite its name on Schedule 1 annexed hereto, at the purchase price indicated in the Prospectus.

The Company will prepare and file with the Commission, in accordance with the rules and regulations of the Commission, promptly upon request by the Underwriters or counsel to the Underwriters, any amendments to the Registration Statement or amendments or supplements to the Prospectus that may be necessary or advisable in connection with the distribution of the Securities by the Underwriters, and will use its best efforts to cause any such amendment to the Registration Statement to be declared effective by the Commission as promptly as possible.

(d) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act, any event occurs as a result of which the Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if for any other reason it is necessary at any time to amend or supplement the Prospectus to comply with the Act or the rules or regulations of the Commission thereunder, the Company will promptly notify the Underwriters thereof and, subject to Section 4(a) hereof, will prepare and file with the Commission, at the Company's expense, an amendment to the Registration Statement or an amendment or supplement to the Prospectus that corrects such statement or omission or effects such compliance. (e) Intentionally left blank.

In rendering any such opinion, such counsel may rely, as to matters of fact, to the extent such counsel deems proper, on certificates of responsible officers of the Company and public officials, copies of which certificates will be provided to the Underwriters, and, as to matters of the laws of certain jurisdictions, on the opinions of other counsel to the Company, which opinions shall also be delivered to the Underwriters, in form and substance acceptable to the Underwriters, if such other counsel expressly authorize such reliance and counsel to the Company expressly states in their opinion that such counsel's and the Underwriters' reliance upon such opinion is justified.

B. At the Firm Closing Date and the Option Closing Date, if any, the Representative shall have received from the Certified Public Accountants, a letter, dated as of the Firm Closing Date or the Option Closing Date, as the case may be, to the effect that it reaffirms that statements made in the letter furnished pursuant to subsection A of this Section 6(e), except that the specified date referred to shall be a date not more than five (5) days prior to the Firm Closing Date 20 or the Option Closing Date, as the case may be, and, if the Company has elected to rely on Rule 430A of the Rules and Regulations, to the further effect that they have carried out procedures as specified in clause (v) of subsection A of this Section 6(e) with respect to certain amounts, percentages and financial information as specified by the Representative and deemed to be a part of the Registration Statement pursuant to Rule 430A(b) and have found such amounts, percentages and financial information to be in agreement with the records specified in such clause (v).

(f) No stop order suspending the effectiveness of the Registration Statement or any amendment thereto shall have been issued, and no proceedings for that purpose shall have been instituted or threatened or contemplated by the Commission. (g) Subsequent to the respective dates as of which information is given in the Registration Statement and the Prospectus, there shall not have been any material adverse change, or any development involving a prospective material adverse change, in the business, operations, condition (financial or otherwise), earnings or prospects of the Company, except in each case as described in or contemplated by the Prospectus (exclusive of any amendment or supplement thereto). (h) The Underwriters shall have received a certificate, dated the Firm Closing Date, of the Chief Executive Officer and the Secretary of the Company to the effect set forth in subparagraphs (d) through (f) above. (i) The Common Stock shall be qualified in such jurisdictions as the Underwriters may reasonably request pursuant to Section 4(c), and each such qualification shall be in effect and not subject to any stop order or other proceeding on the Firm Closing Date.

The Company shall furnish to the Underwriters such conformed copies of such opinions, certificates, letters and documents in such quantities as the Underwriters and counsel for the Underwriters shall reasonably request. The obligation of the Underwriters to purchase and pay for any Option Shares shall be subject, in its discretion, to each of the foregoing conditions, except that all references to the Firm Securities and the Firm Closing Date shall be deemed to refer to such Option Shares and the related Option Closing Date, respectively. 7. INDEMNIFICATION AND CONTRIBUTION. (a) The Company agrees to indemnify and hold harmless the Underwriters and each person, if any, who controls the Underwriters within the meaning of Section 15 of the Act or Section 20 of the 1934 Act against any losses, claims, damages, or liabilities, joint or several, to which the Underwriters, or such controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (1) any untrue statement or alleged untrue statement of any material fact contained in (A) the Registration Statement or any amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, or (B) any application or other document, or any amendment or supplement thereto, executed by the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify the Securities under the Blue Sky or securities laws thereof or filed with the Commission or any securities association or securities exchange (each an "Application"), or (2) the omission or alleged omission to state in such Registration Statement or any amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, or any Application a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse, as incurred, the Underwriters and such controlling person for any legal or other expenses reasonably incurred by the Underwriters or such controlling person in connection with investigating or defending against any loss, claim, damage, liability, action, investigation, litigation or proceeding; PROVIDED, HOWEVER, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement or any amendment thereto, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or any Application in reliance upon and in conformity with written information furnished to the Company by the Underwriters, specifically for use therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have. The Company will not, without the prior written consent of the Underwriters, or controlling person, settle 22 or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not the Underwriters or any person who controls the Underwriters or within the meaning of Section 15 of the Act or Section 20 of the 1934 Act is a party to such claim, action, suit or proceeding), unless such settlement, compromise or consent includes an unconditional release of the Underwriters and each such controlling person from all liability arising out of such claim, action, suit or proceeding. (b) The Underwriters will indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the 1934 Act against, any losses, claims, damages or liabilities to which the Company or any such director, officer, or controlling person may become subject under the Act or otherwise, but only insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or any amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, or any Application, or (ii) the omission or the alleged omission to state therein a material fact required to be stated in the Registration Statement or any amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, or any Application, or necessary to make the statements therein not misleading, 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 reliance upon and in conformity with written information furnished to the Company by the Underwriters specifically for use therein; and, subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses reasonably incurred by the Company or any such director, officer, or controlling person in connection with investigating or defending against any such loss, claim, damage, liability, action investigation, litigation or proceedings, in respect thereof. This indemnity agreement will be in addition to any liability which the Underwriters may otherwise have. (c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party of the commencement thereof; but the omission 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 Section 7. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein 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; PROVIDED, HOWEVER, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the 23 defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence or (ii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the consent of the indemnifying party. (d) In circumstances in which the indemnity obligation provided for in the preceding paragraphs of this Section 7 is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Securities, or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total proceeds from the Offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission, and the other equitable considerations appropriate in the circumstances. The Company and the Underwriters agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). Notwithstanding any other provision of this paragraph (d), the Underwriters shall not be obligated to make contributions hereunder that in the aggregate exceeding the total public offering price of the Securities purchased by the Underwriters under this Agreement, less the aggregate amount of any damages that the Underwriters have otherwise been required to pay in respect of the same or any substantially similar claim, and no person guilty of fraudulent misrepresentation (within the meaning of Section 11 (f) of the Act) shall be entitled to contribution from any person who is not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Underwriters, and each director of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of 24 Section 15 of the Act or Section 20 of the 1934 Act, shall have the same rights to contribution as the Company. 8. SUBSTITUTION OF UNDERWRITERS. If any Underwriter shall for any reason not permitted hereunder cancel its obligations to purchase the Firm Securities hereunder, or shall fail to take up and pay for the number of Firm Securities set forth opposite names in Schedule 1 hereto upon tender of such Firm Securities in accordance with the terms hereof, then: (a) If the aggregate number of Firm Securities which such Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Firm Securities, the other Underwriters shall be obligated to purchase the Firm Securities which such defaulting Underwriter agreed but failed to purchase. (b) If any Underwriter so defaults and the agreed number of Firm Securities with respect to which such default or defaults occurs is more than 10% of the total number of Firm Securities, the remaining Underwriters shall have the right to take up and pay for the Firm Securities which the defaulting Underwriter agreed but failed to purchase. If such remaining Underwriters do not, at the Firm Closing Date, take up and pay for the Firm Securities which the defaulting Underwriter agreed but failed to purchase, the time for delivery of the Firm Securities shall be extended to the next business day to allow the remaining Underwriters the privilege of substituting within twenty-four hours (including nonbusiness hours) another underwriter or underwriters satisfactory to the Company. If no such underwriter or underwriters shall have been substituted as aforesaid, within such twenty-four hour period, the time of delivery of the Firm Securities may, at the option of the Company, be again extended to the next following business day, if necessary, to allow the Company the privilege of finding within twenty-four hours (including nonbusiness hours) another underwriter or underwriters to purchase the Firm Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase. If it shall be arranged for the remaining Underwriter or substituted Underwriters to take up the Firm Securities of the defaulting Underwriter as provided in this section, (i) the Company or the Underwriters shall have the right to postpone the time of delivery for a period of not more than seven business days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other document or arrangements, and the Company agrees promptly to file any amendments to the Registration Statement or supplements to the Prospectus which may thereby be made necessary, and (ii) the respective numbers of Firm Securities to be purchased by the remaining Underwriters or substituted Underwriters shall be taken as the basis of the underwriting obligation for all purposes of this agreement. If in the event of a default by any Underwriter and the remaining Underwriters shall not take up and pay for all the Firm Securities agreed to be purchased by the defaulting Underwriter or substitute another underwriter or underwriters as aforesaid, the Company shall not find or shall not elect to seek another underwriter or underwriters for such Firm Securities as aforesaid, then this Agreement shall terminate. 25 If, following exercise of the option provided in Section 2(c) hereof, any Underwriter or Underwriters shall for any reason not permitted hereunder cancel their obligations to purchase Option Shares at the Option Closing Date, or shall fail to take up and pay for the number of Option Shares, which it became obligated to purchase at the Option Closing Date upon tender of such Option Shares in accordance with the terms hereof, then the remaining Underwriters or substituted Underwriters may take up and pay for the Option Shares of the defaulting Underwriters in the manner provided in Section 8(b) hereof. If the remaining Underwriters or substituted Underwriters shall not take up and pay for all such Option Shares, the Underwriters shall be entitled to purchase the number of Option Shares for which there is no default or, at their election, the option shall terminate, the exercise thereof shall be of no effect. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section. In the event of termination, there shall be no liability on the part of any non-defaulting Underwriter to the Company, provided that the provisions of this Section 8 shall not in any event affect the liability of any defaulting Underwriter to the Company arising out of such default. 9. SURVIVAL. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Company, any of its officers or directors and the Underwriter set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Company, any of its officers or directors, the Underwriter or any controlling person referred to in Section 7 hereof, and (ii) delivery of and payment for the Securities. The respective agreements, covenants, indemnities and other statements set forth in Sections 4 and 7 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement. 10. TERMINATION. (a) This Agreement may be terminated with respect to the Firm Securities or any Option Shares in the sole discretion of the Representative by notice to the Company given prior to the Firm Closing Date or the related Option Closing Date, respectively, in the event that the Company shall have failed, refused or been unable to perform all obligations and satisfy all conditions on its part to be performed or satisfied under Section 6 hereunder at or prior thereto or if at or prior to the Firm Closing Date or such Option Closing Date, respectively: (1) the Company sustains a loss by reason of explosion, fire, flood, accident or other calamity, which, in the opinion of the Underwriter, substantially affects the value of the properties of the Company or which materially interferes with the operation of the business of the Company regardless of whether such loss shall have been insured; there shall have been any material adverse change, or any development involving a prospective material adverse change (including, without limitation, a change in management or control of the Company), in the business, operations, condition (financial or otherwise), earnings or prospects of the Company, except in each case as described in or contemplated by the Prospectus (exclusive of any amendment or supplement thereto); 26 (2) any action, suit or proceeding shall be threatened, instituted or pending, at law or in equity, against the Company, by any person or by any federal, state, foreign or other governmental or regulatory commission, board or agency wherein any unfavorable result or decision could materially adversely affect the business, operations, condition (financial or otherwise), earnings or prospects of the Company; (3) trading in the Common Stock shall have been suspended by the Commission, the NASD or on Nasdaq, or trading in securities generally on the New York Stock Exchange shall have been suspended or minimum or maximum prices shall have been established on either such exchange or quotation system; (4) a banking moratorium shall have been declared by New York or United States authorities; (5) there shall have been (A) an outbreak of hostilities between the United States and any foreign power (or, in the case of any ongoing hostilities, a material escalation thereof), (B) an outbreak of any other insurrection or armed conflict involving the United States or (C) any other calamity or crisis or material change in financial, political or economic conditions, having an effect on the financial markets that, in any case referred to in this clause (5), in the sole judgment of the Underwriter makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities as contemplated by the Registration Statement; and (6) termination of this Agreement pursuant to this Section 10 shall be without liability of any party to any other party, except as provided in Section 5(b) and Section 7 hereof. 11. INFORMATION SUPPLIED BY THE UNDERWRITER.

No waiver shall be deemed a continuing waiver or waiver in respect of any other or subsequent breach or default, unless expressly so stated in writing. 15. APPLICABLE LAW.

AND NEIDIGER TUCKER BRUNNER, INC. REPRESENTATIVE'S WARRANT AGREEMENT REPRESENTATIVE'S WARRANT AGREEMENT dated as of ____________, 1999 by and between ENTROPIN, INC., (the "Company") and NEIDIGER TUCKER BRUNNER, INC. ("Representative"). W I T N E S S E T H: ------------------- WHEREAS, the Company proposes to issue to the Representative _______ warrants (each a "Representative's Warrant") each to purchase one share of the Company's $.001 par value common stock, (the "Common Stock"). WHEREAS, the Representative has agreed, pursuant to the underwriting agreement (the "Underwriting Agreement") dated _________, 1999 by and between the Representative and the Company, to act as the Representative in connection with the Company's proposed public offering (the "Public Offering") of _________ shares of Common Stock (the "Offering Securities"); and WHEREAS, the Representative's Stock Warrants to be issued pursuant to this Agreement will be issued on the Firm Closing Date (as such term is defined in the Underwriting Agreement) by the Company to the Representative in consideration for, and as part of, the Representative's compensation in connection with the Representative's acting as the Representative pursuant to the Underwriting Agreement; NOW, THEREFORE, in consideration of the premises, the payment by the Representative to the Company of One Hundred Dollars ($100.00), the agreements herein set forth and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 1. GRANT. The Holder (as defined in Section 3 below) is hereby granted the right to purchase, at any time from ____________, 2000 until 5:00 p.m., New York time, __________, 2004, up to ________ shares of Common Stock, at an initial purchase price (subject to adjustment as provided in Section 8 hereof) of $______ per share of Common Stock subject to the terms and conditions of this Agreement. The securities issuable upon exercise of the Representative's Warrant are sometimes referred to herein as the "Representative's Securities." 2. WARRANT CERTIFICATES. The warrant certificate (the "Representative's Warrant Certificate") to be delivered pursuant to this Agreement shall be in the form set forth in Exhibit A attached hereto and made a part hereof, with such appropriate insertions, omissions, substitutions, and other variations as required or permitted by this Agreement. 3. EXERCISE OF REPRESENTATIVE'S WARRANT. (a) The Representative's Warrant is exercisable during the term set forth in Section 1 hereof payable by certified or cashier's check or money order in lawful money of the United States. Upon surrender of Representative's Warrant Certificate with the annexed Form of Election to Purchase duly executed, together with payment of the Purchase Price (as hereinafter defined) for the Representative's Securities (and such other amounts, if any, arising pursuant to Section 4 hereof) at the Company's principal office, the registered holder of a Representative's Warrant Certificate ("Holder" or "Holders") shall be entitled to receive a certificate or certificates for the Representative's Securities so purchased. The purchase rights represented by each Representative's Warrant Certificate are exercisable at the option of the Holder or Holders thereof, in whole or in part as to Representative's Securities. The Representative's Warrant may be exercised to purchase all or any part of the Representative's Securities represented thereby. In the case of the purchase of less than all the Representative's Securities purchasable on the exercise of the Representative's Warrant represented by a Representative's Warrant Certificate, the Company shall cancel the Representative's Warrant Certificate represented thereby upon the surrender thereof and shall execute and deliver a new Representative's Warrant Certificate of like tenor for the balance of the Representative's Securities purchasable thereunder. (b) In lieu of the payment of cash upon exercise of the Representative's Warrant as provided in Section 3(a), the Holder may exercise the Representative's Warrant by surrendering the Representative's Warrant Certificate at the principal office of the Company, accompanied by a notice stating (i) the Holder's intent to effect such exercise by an exchange, (ii) the Common Stock to be issued upon the exchange, (iii) whether Representative's Warrants are to be surrendered in connection with the exchange, and (iv) the date on which the Holder requests that such exchange is to occur. The Purchase Price for the Representative's Securities to be acquired in the exchange shall be paid by the surrender as indicated in the notice, of Representative's Warrants, having a "Value", as defined below, equal to the Purchase Price. "Value" as to each Representative's Warrant shall mean the difference between the "Market Price", as hereinafter defined, of a share of Common Stock and the then Purchase Price for a share of Common Stock. By way of example of the application of the formula, assume that the Market Price of the Common Stock is $8.00, the Purchase Price of the Representative's Warrant is $6.00. On such assumptions, the Value of a Representative's Warrant is $2.00 ($8.00-$6.00) and therefore for each three (3) Representative's Warrants surrendered, the Holder could acquire one (1) share of Common Stock in the exchange. Notwithstanding the example, the Holder shall not be limited to exchanging Representative's Warrants for Common Stock. 2 The Warrant Exchange shall take place on the date specified in the notice or if the date the notice is received by the Company is later than the date specified in the notice, on the date the notice is received by the Company. 4. ISSUANCE OF CERTIFICATES. Upon the exercise of the Representative's Warrant and payment of the Purchase Price therefor, the issuance of certificates representing the Representative's Securities or other securities, properties or rights underlying such Representative's Warrant, shall be made forthwith (and in any event within five (5) business days thereafter) without further charge to the Holder thereof, and such certificates shall (subject to the provisions of Sections 5 and 7 hereof) be issued in the name of, or in such names as may be directed by, the Holder thereof; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any such certificates in a name other than that of the Holder, and the Company shall not be required to issue or deliver such certificates unless or until the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. The Representative's Warrant Certificates and the certificates representing the Representative's Securities or other securities, property or rights (if such property or rights are represented by certificates) shall be executed on behalf of the Company by the manual or facsimile signature of the then present Chairman or Vice Chairman of the Board of Directors or President or Vice President of the Company, attested to by the manual or facsimile signature of the then present Secretary or Assistant Secretary or Treasurer or Assistant Treasurer of the Company. The Representative's Warrant Certificates shall be dated the date of issuance thereof by the Company upon initial issuance, transfer or exchange. 5. RESTRICTION ON TRANSFER OF REPRESENTATIVE'S WARRANT. The Holder of a Representative's Warrant Certificate (and its Permitted Transferee, as defined below), by its acceptance thereof, covenants and agrees that until ____________, 2000 (one year following the effective date of the Public Offering), the Representative's Warrant may not be sold, transferred, assigned, hypothecated or otherwise disposed of, in whole or in part, except to officers and partners of the Representatives, or any Public Offering selling group member and their respective officers and partners, ("Permitted Transferees"). Thereafter the Representative's Warrant may be transferred, assigned, hypothecated or otherwise disposed of in compliance with applicable law. 6. PURCHASE PRICE. (a) INITIAL AND ADJUSTED PURCHASE PRICE. Except as otherwise provided in Section 8 hereof, the initial purchase price of the Representative's Securities is set forth in Section 1. The adjusted purchase price shall be the price which shall result from time to time from any and all adjustments of the initial purchase price in accordance with the provisions of Section 8 hereof. (b) PURCHASE PRICE. The term "Purchase Price" herein shall mean the initial purchase price or the adjusted purchase price, depending upon the context. 3 7. REGISTRATION RIGHTS. (a) REGISTRATION UNDER THE SECURITIES ACT OF 1933 AS AMENDED ("ACT"). The Representative's Warrant may have not been registered under the Act. The Representative's Warrant Certificates may bear the following legend: "The securities represented by this certificate have not been registered under the Securities Act of 1933 (the "Act"), and may not be offered for sale or sold except pursuant to (i) an effective registration statement under the Act, or (ii) an opinion of counsel, if such opinion and counsel shall be reasonably satisfactory to counsel to the issuer, that an exemption from registration under the Act is available." (b) DEMAND REGISTRATION. (1) At any time commencing on the first anniversary of and expiring on the fifth anniversary of the effective date of the Company's Registration Statement relating to the Public Offering (the "Effective Date"), the Holders of a Majority (as hereinafter defined) in interest of the Representative's Warrant, or the Majority in interest of the Representative's Securities (assuming the exercise of all of the Representative's Warrant) shall have the right, exercisable by written notice to the Company, to have the Company prepare and file with the U.S. Securities and Exchange Commission (the "Commission"), on one (1) occasion, a registration statement on Form S-1 or SB-2 or other appropriate form, and such other documents, including a prospectus, as may be necessary in the opinion of both counsel for the Company and counsel for the Holders, in order to comply with the provisions of the Act, so as to permit a public offering and sale, of the Representative's Securities by such Holders and any other Holders of the Representative's Warrant and/or the Representative's Securities who notify the Company within fifteen (15) business days after receipt of the notice described in Section 7(b)(2). (2) The Company covenants and agrees to give written notice of any registration request under this Section 7(b) by any Holders to all other registered Holders of the Representative's Warrant and the Representative's Securities within ten (10) calendar days from the date of the receipt of any such registration request. (3) For purposes of this Agreement, the term "Majority" in reference to the Holders of the Representative's Warrant or Representative's Securities, shall mean in excess of fifty percent (50%) of the then outstanding Representative's Warrant or Representative's Securities that (i) are not held by the Company, an affiliate, officer, creditor, employee or agent thereof or any of their respective affiliates, members of their family, persons acting as nominees or in conjunction therewith, or (ii) have not been resold to the public pursuant to a registration statement filed with the Commission under the Act. (4) The Company shall have no obligation to prepare and file a registration statement pursuant to this Section 7(b) if, within twenty (20) days after the Company receives such a demand for registration, the Company agrees, or insiders who own individually more than 5% of the Company's outstanding Common Stock agree, to purchase the Holder's Warrants and/or Warrant Shares from the requesting Holders at a price equal to the difference between the Exercise Price then 4 in effect and the then current market price of the Company's Common Stock. The market price of the Company's Common Stock shall be the average of the closing asked prices for the Company's Common Stock during the ten (10) business days period preceding such request. (c) PIGGYBACK REGISTRATION. (1) If, at any time within the period commencing on the first anniversary and expiring on the sixth anniversary of the Effective Date, the Company should file a registration statement with the Commission under the Act (other than in connection with a merger or other business combination transaction or pursuant to Form S-8), it will give written notice at least twenty (20) calendar days prior to the filing of each such registration statement to the Representative and to all other Holders of the Representative's Warrant and/or the Representative's Securities of its intention to do so. If a Representative or other Holders of the Representative's Warrant and/or the Representative's Securities notify the Company within fifteen (15) calendar days after receipt of any such notice of its or their desire to include any Representative's Securities in such proposed registration statement, the Company shall afford the Representative and such Holders of the Representative's Warrant and/or Representative's Securities the opportunity to have any such Representative's Securities registered under such registration statement. Notwithstanding the provisions of this Section 7(c)(1) and the provisions of Section 7(d), the Company shall have the right at any time after it shall have given written notice pursuant to this Section 7(c)(1) (irrespective of whether a written request for inclusion of any such securities shall have been made) to elect not to file any such proposed registration statement, or to withdraw the same after the filing but prior to the effective date thereof. (2) If the managing underwriter of an offering to which the above piggyback rights apply, in good faith and for valid business reasons, objects to such rights, such objection shall preclude such inclusion. (d) COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION. In connection with any registrations under Sections 7(b) and 7(c) hereof, the Company covenants and agrees as follows: (1) The Company shall use its best efforts to file a registration statement within thirty (30) calendar days of receipt of any demand therefor pursuant to Section 7(b); provided, however, that the Company shall not be required to produce audited or unaudited financial statements for any period prior to the date such financial statements are required to be filed in a report on Form 10-K or Form 10-Q (or Form 10-KSB or Form 10-QSB), as the case may be. The Company shall use its best efforts to have any registration statement declared effective at the earliest possible time, and shall furnish each Holder desiring to sell Representative's Securities such number of prospectuses as shall reasonably be requested. (2) The Company shall maintain the effectiveness of the registration statement for a period of time equal to the lesser of 9 months or until such time as all of the Warrant Shares have been sold pursuant to the registration statement. (3) The Company shall pay all costs (excluding fees and expenses of Holders' counsel and any underwriting discounts or selling fees, expenses or commissions), fees and 5 expenses in connection with any registration statement filed pursuant to Sections 7(b) and 7(c) hereof including, without limitation, the Company's legal and accounting fees, printing expenses, blue sky fees and expenses. (4) The Company will use its best efforts to qualify or register the Representative's Securities included in a registration statement for offering and sale under the securities or blue sky laws of such states as reasonably are requested by the Holders, provided that the Company shall not be obligated to execute or file any general consent to service of process or to qualify as a foreign corporation to do business under the laws of any such jurisdiction. (5) The Company shall indemnify the Holders of the Representative's Securities to be sold pursuant to any registration statement and each person, if any, who controls such Holders within the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange Act of 1934 (the "Exchange Act"), against all loss, claim, damage, expense or liability (including all expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which any of them may become subject under the Act, the Exchange Act or otherwise, arising from such registration statement, but only to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify the Representative contained in Section 8 of the Underwriting Agreement. (6) The Holders of the Representative's Securities to be sold pursuant to a registration statement, and their successors and assigns, shall indemnify the Company, its officers and directors and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against all loss, claim, damage or expense or liability to which they may become subject under the Act, the Exchange Act or otherwise, arising from information furnished by or on behalf of such Holders, or their successors or assigns, for specific inclusion in such registration statement to the same extent and with the same effect as the provisions contained in Section 8 of the Underwriting Agreement pursuant to which the Representative has agreed to indemnify the Company. (7) Nothing contained in this Agreement shall be construed as requiring the Holders to exercise their Representative's Warrant prior to the initial filing of any registration statement or the effectiveness thereof, provided that such Holders have made arrangements reasonably satisfactory to the Company to pay the exercise price from the proceeds of such offering. (8) The Company shall furnish to each Representative for the offering, if any, such documents as such Representative may reasonably require. (9) The Company shall as soon as practicable after the effective date of the registration statement, and in any event within 15 months thereafter, make "generally available to its security holders" (within the meaning of Rule 158 under the Act) an earnings statement (which need not be audited) complying with Section 11(a) of the Act and covering a period of at least 12 consecutive months beginning after the effective date of the registration statement. 6 (10) The Company shall deliver promptly to each Holder participating in the offering requesting the correspondence described below and any managing Representative copies of all correspondence between the Commission and the Company, its counsel or auditors with respect to the registration statement and permit each Holder and Representative to do such investigation, upon reasonable advance notice, with respect to information contained in or omitted from the registration statement as it deems reasonably necessary to comply with applicable securities laws or rules of the National Association of Securities Dealers, Inc. ("NASD"). Such investigation shall include access to books, records and properties and opportunities to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable times and as often as any such Holder shall reasonably request. (11) The Company shall enter into an underwriting agreement with the managing underwriter selected for such underwriting by Holders holding a Majority of the Representative's Securities requested to be included in such underwriting, provided, however that such managing underwriter shall be reasonably acceptable to the Company, except that in connection with an offering for which the Holders have piggyback rights, the Company shall have the sole right to select the managing underwriter or underwriters. Such underwriting agreement shall be satisfactory in form and substance to the Company, a Majority of such Holders (in respect of a registration under Section 7(b) only) and such managing underwriter, and shall contain such representations, warranties and covenants by the Company and such other terms as are customarily contained in agreements of that type. The Holders shall be parties to any underwriting agreement relating to an underwritten sale of their Representative's Securities. Such Holders shall not be required to make any representations or warranties to or agreements with the Company or the underwriters except as they may relate to such Holders and their intended methods of distribution. 8. ADJUSTMENTS TO PURCHASE PRICE AND NUMBER OF SECURITIES. (a) COMPUTATION OF ADJUSTED PURCHASE PRICE. Except as hereinafter provided, in case the Company shall at any time after the date hereof issue or sell any shares of Common Stock (other than the issuances referred to in Section 8(g) hereof), including shares held in the Company's treasury, for a consideration per share less than the "Market Price" (as defined in Section 8(a)(6) hereof) per share of Common Stock on the date immediately prior to the issuance or sale of such shares, or without consideration, then forthwith upon any such issuance or sale, the Purchase Price of the Common Stock shall (until another such issuance or sale) be reduced to the price (calculated to the nearest full cent) determined by dividing (1) the product of (a) the Purchase Price in effect immediately before such issuance or sale and (b) the sum of (i) the total number of shares of Common Stock outstanding immediately prior to such issuance or sale, and (ii) the number of shares determined by dividing (A) the aggregate consideration, if any, received by the Company upon such sale or issuance, by (B) the Market Price, and by (2) the total number of shares of Common Stock outstanding immediately after such issuance or sale provided, however, that in no event shall the Purchase Price be adjusted pursuant to this computation to an amount in excess of the Purchase Price in effect immediately prior to such computation, except in the case of a combination of outstanding shares of Common Stock, as provided by Section 8(c) hereof. 7 For the purposes of this Section 8, the term "Purchase Price" shall mean the Purchase Price of the Common Stock forming a part of the Representative's Securities set forth in Section 6 hereof, as adjusted from time to time pursuant to the provisions of this Section 8. For the purposes of any computation to be made in accordance with this Section 8(a), the following provisions shall be applicable: (1) In case of the issuance or sale of shares of Common Stock (or of other securities deemed hereunder to involve the issuance or sale of shares of Common Stock) for a consideration part or all of which shall be cash, the amount of the cash consideration therefor shall be deemed to be the amount of cash received by the Company for such shares (or, if shares of Common Stock are offered by the Company for subscription, the subscription price, or, if such securities shall be sold to Representatives or dealers for public offering without a subscription offering, the initial public offering price) before deducting therefrom any compensation paid or discount allowed in the sale, underwriting or purchase thereof by Representatives or dealers or others performing similar services, or any expenses incurred in connection therewith. (2) In case of the issuance or sale (otherwise than as a dividend or other distribution on any stock of the Company, and otherwise than on the exercise of options, rights or warrants or the conversion or exchange of convertible or exchangeable securities) of shares of Common Stock (or of other securities deemed hereunder to involve the issuance or sale of shares of Common Stock) for a consideration part or all of which shall be other than cash, the amount of the consideration therefor other than cash shall be deemed to be the value of such consideration as determined in good faith by the Board of Directors of the Company. (3) Shares of Common Stock issuable by way of dividend or other distribution on any stock of the Company shall be deemed to have been issued immediately after the opening of business on the day following the record date for the determination of stockholders entitled to receive such dividend or other distribution and shall be deemed to have been issued without consideration. (4) The reclassification of securities of the Company other than shares of Common Stock into securities including shares of Common Stock shall be deemed to involve the issuance of such shares of Common Stock for a consideration other than cash immediately prior to the close of business on the date fixed for the determination of security holders entitled to receive such shares, and the value of the consideration allocable to such shares of Common Stock shall be determined as provided in Section 8(a)(2). (5) The number of shares of Common Stock at any one time outstanding shall include the aggregate number of shares of Common Stock issued or issuable (subject to readjustment upon the actual issuance thereof) upon the exercise of options, rights or warrants and upon the conversion or exchange of convertible or exchangeable securities. 8 (6) As used herein in the phrase "Market Price" at any date shall be deemed to be the last reported sale price, or, in the case no such reported sale takes place on such day, the average of the last reported sales prices for the last three (3) trading days, in either case as officially reported by the principal securities exchange on which the Common Stock is listed or admitted to trading, or, if the Common Stock is not listed or admitted to trading on any national securities exchange, the average closing bid price as furnished by the NASD through the NASD Automated Quotation System ("NASDAQ") or similar organization if NASDAQ is no longer reporting such information, or if the Common Stock is not quoted on NASDAQ, as determined in good faith by resolution of the Board of Directors of the Company, based on the best information available to it. (b) OPTIONS, RIGHTS, WARRANT AND CONVERTIBLE AND EXCHANGEABLE SECURITIES. Except in the case of the Company issuing rights to subscribe for shares of Common Stock distributed to all the stockholders of the Company and Holders of Representative's Warrant pursuant to Section 8(i) hereof, if the Company shall at any time after the date hereof issue options, rights or warrants to purchase shares of Common Stock, or issue any securities convertible into or exchangeable for shares of Common Stock (other than the issuances referred to in Section 8(g) hereof), (i) for a consideration per share less than the Market Price (including the issuance thereof without consideration such as by way of dividend or other distribution), or (ii) without consideration, the Purchase Price in effect immediately prior to the issuance of such options, rights or warrants, or such convertible or exchangeable securities, as the case may be, shall be reduced to a price determined by making a computation in accordance with the provisions of Section 8(a) hereof, provided that: (1) The aggregate maximum number of shares of Common Stock issuable or that may become issuable under such options, rights or warrants (assuming exercise in full even if not then currently exercisable or currently exercisable in full) shall be deemed to be issued and outstanding at the time such options, rights or warrants were issued, and for a consideration equal to the minimum purchase price per share provided for in such options, rights or warrants at the time of issuance, plus the consideration (determined in the same manner as consideration received on the issue or sale of shares in accordance with the terms of the Representative's Warrant), if any, received by the Company for such options, rights or warrants; provided, however, that upon the expiration or other termination of such options, rights or warrants, if any thereof shall not have been exercised, the number of shares of Common Stock deemed to be issued and outstanding pursuant to this Section 8(b)(1) (and for the purposes of Section 8(a)(5) hereof) shall be reduced by such number of shares as to which options, warrants and/or rights shall have expired or terminated unexercised, and such number of shares shall no longer be deemed to be issued and outstanding, and the Purchase Price then in effect shall forthwith be readjusted and thereafter be the price which it would have been had adjustment been made on the basis of the issuance only of shares actually issued or issuable upon the exercise of those options, rights or warrants as to which the exercise rights shall not be expired or terminated unexercised. (2) The aggregate maximum number of shares of Common Stock issuable upon conversion or exchange of any convertible or exchangeable securities (assuming conversion or exchange in full even if not then currently convertible or exchangeable in full) shall be deemed to be issued and outstanding at the time of issuance of such securities, and for a consideration equal to the 9 consideration (determined in the same manner as consideration received on the issue or sale of shares of Common Stock in accordance with the terms of the Representative's Warrant) received by the Company for such securities, plus the minimum consideration, if any, receivable by the Company upon the conversion or exchange thereof; provided, however, that upon the expiration or other termination of the right to convert or exchange such convertible or exchangeable securities (whether by reason or redemption or otherwise), the number of shares deemed to be issued and outstanding pursuant to this Section 8(b)(2) (and for the purpose of Section 8(a)(5) hereof) shall be reduced by such number of shares as to which the conversion or exchange rights shall have expired or terminated unexercised, and such number of shares shall no longer be deemed to be issued and outstanding and the Purchase Price then in effect shall forthwith be readjusted and thereafter be the price which it would have been had adjustment been made on the basis of the issuance only of the shares actually issued or issuable upon the conversion or exchange of those convertible or exchangeable securities as to which the conversion or exchange rights shall not have expired or terminated unexercised. (3) If any change shall occur in the price per share provided for in any of the options, rights or warrants referred to in Section 8(b)(1), or in the price per share at which the securities referred to in Section 8(b)(2) are convertible or exchangeable, and if a change in the Purchase Price has not occurred by reason of the event giving rise to the change in the price per share of such other options, rights, warrants, or convertible or exchangeable securities, such options, rights or warrants or conversion or exchange rights, as the case may be, to the extent not theretofore exercised, the shall be deemed to have expired or terminated on the date when such price change became effective in respect of shares not theretofore issued pursuant to the exercise or conversion or exchange thereof, and the Company shall be deemed to have issued upon such date new options, rights or warrants or convertible or exchangeable securities at the new price in respect of the number of shares issuable upon the exercise of such options, rights or warrants or the conversion or exchange of such convertible or exchangeable securities. (c) SUBDIVISION AND COMBINATION. In case the Company shall at any time issue any shares of Common Stock in connection with a stock dividend in shares of Common Stock or subdivide or combine the outstanding shares of Common Stock, the Purchase Price shall forthwith be proportionately decreased in the case of a stock dividend or a subdivision or increased in the case of combination. (d) ADJUSTMENT IN NUMBER OF SECURITIES. Upon each adjustment of the Purchase Price pursuant to the provisions of this Section 8, the number of Representative's Securities issuable upon the exercise of the Representative's Warrant shall be adjusted to the nearest whole share by multiplying a number equal to the Purchase Price in effect immediately prior to such adjustment by the number of Representative's Securities issuable upon exercise of the Representative's Warrant immediately prior to such adjustment and dividing the product so obtained by the adjusted Purchase Price. (e) DEFINITION OF COMMON STOCK. For the purpose of this Agreement, the term "Common Stock" shall mean the class of stock designated as Common Stock in the Certificate of Incorporation, of the Company as it may be amended as of the date hereof. 10 (f) RECLASSIFICATION, MERGER OR CONSOLIDATION. The Company will not merge, reorganize or take any other action which would terminate the Representative's Warrant without first making adequate provision for the Representative's Warrant. In case of any reclassification or change of the outstanding shares of Common Stock issuable upon exercise of the outstanding warrants (other than a change in par value to no par value, or from nor par value to par value, or as a result of a subdivision or combination), or in case of any consolidation of the Company with, or merger of the Company with, or merger of the Company into, another corporation (other than a consolidation or merger in which the Company is the continuing corporation and which does not result in any reclassification or change of the outstanding Common Stock except a change as a result of a subdivision or combination of such shares or a change in par value, as aforesaid), or in the case of a sale or conveyance to another corporation or other entity of the property of the Company as an entirety or substantially as an entirety, the Holders of each Representative's Warrant then outstanding or to be outstanding shall have the right thereafter (until the expiration of such Representative's Warrant) to purchase, upon exercise of such Representative's Warrant, the kind and number of shares of stock and other securities and property receivable upon such reclassification, change, consolidation, merger, sale or conveyance as if the Holders were the owner of the shares of Common Stock underlying the Representative's Warrant immediately prior to any such events at a price equal to the product of (x) the number of shares issuable upon exercise of the Representative's Warrant and (y) the Purchase Price in effect immediately prior to the record date for such reclassification, change, consolidation, merger, sale or conveyance, as if such Holders had exercised the Representative's Warrant. In the event of a consolidation, merger, sale or conveyance of property, the corporation formed by such consolidation or merger, or acquiring such property, shall execute and deliver to the Holders a supplemental Representative's warrant agreement to such effect. Such supplemental Representative's warrant agreement shall provide for adjustments which shall be identical to the adjustment provided for in this Section 8. The provisions of this Section 8(f) shall similarly apply to successive consolidations or mergers. (g) NO ADJUSTMENT OF PURCHASE PRICE IN CERTAIN CASES. No adjustment of the Purchase Price shall be made: (1) Upon the issuance or sale of (i) the Representative's Warrant or the securities underlying the Representative's Warrant, (ii) the securities sold pursuant to the Public Offering (including those sold upon exercise of the Representative's over-allotment option), or (iii) the shares issuable pursuant to the options, warrants, rights, stock purchase agreements or convertible or exchangeable securities outstanding or in effect on the date hereof as described in the prospectus relating to the Public Offering. (2) If the amount of said adjustments shall aggregate less than two ($.02) cents for one (1) share of Common Stock; provided, however, that in such case any adjustment that would otherwise be required then to be made shall be carried forward and shall be made at the time of and together with the next subsequent adjustment which, together with any adjustment so carried forward, shall aggregate at least two ($.02) cents for one (1) share of Common Stock. In addition, Registered Holders shall not be entitled to cash dividends paid by the Company prior to the exercise of any warrant or warrants held by them. 11 9. EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES. Each Representative's Warrant Certificate is exchangeable without expense, upon the surrender thereof by the registered Holders at the principal executive office of the Company, for a new Representative's Warrant Certificate of like tenor and date representing in the aggregate the right to purchase the same number of Representative's Securities in such denominations as shall be designated by the Holders thereof at the time of such surrender. 10. LOSS, THEFT, ETC. OF CERTIFICATES Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of any Representative's Warrant Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it, and reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation of the Representative's Warrant Certificates, if mutilated, the Company will make and deliver a new Representative's Warrant Certificate of like tenor, in lieu thereof. 11. ELIMINATION OF FRACTIONAL INTERESTS. The Company shall not be required to issue certificates representing fractions of shares of Common Stock upon the exercise of the Representative's Warrant, nor shall it be required to issue scrip or pay cash in lieu of fractional interests; provided, however, that if a Holder exercises all Representative's Warrant held of record by such Holder the fractional interests shall be eliminated by rounding any fraction to the nearest whole number of shares of Common Stock or other securities, properties or rights. 12. RESERVATION AND LISTING OF SECURITIES. The Company shall at all times reserve and keep available out of its authorized shares of Common Stock, solely for the purpose of issuance upon the exercise of the Representative's Warrant, such number of shares of Common Stock or other securities and properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of Representative's Warrant and payment of the Purchase Price therefor, all the shares of Common Stock issuable upon such exercise shall be duly and validly issued, fully paid, non-assessable and not subject to the preemptive rights of any stockholder. As long as the Representative's Warrant shall be outstanding, the Company shall use its best efforts to cause the Common Stock to be listed (subject to official notice of issuance) on all securities exchanges on which the Common Stock issued to the public in connection herewith may then be listed or quoted. 13. NOTICES TO REPRESENTATIVE'S WARRANT HOLDERS. Nothing contained in this Agreement shall be construed as conferring upon the Holders the right to vote or to consent or to receive notice as a stockholder in respect of any meetings of stockholders for the election of directors or any other matter, or as having any rights whatsoever as a stockholder of the Company. If, however, at any time prior to the expiration of the Representative's Warrant and their exercise, any of the following events shall occur: (a) the Company shall take a record of the holders of its shares of Common Stock for the purpose of entitling them to receive a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of current or retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company; or 12 (b) the Company shall offer to all the holders of its Common Stock any additional shares of capital stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor; or (c) a dissolution, liquidation or winding up of the Company (other than in connection with a consolidation or merger) or a sale of all or substantially all of its property, assets and business as an entirety shall be proposed; then, in any one or more of said events, the Company shall give written notice of such event at least fifteen (15) calendar days prior to the date fixed as a record date or the date of closing the transfer books for the determination of the stockholders entitled to such dividend, distribution, convertible or exchangeable securities or subscription rights, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify such record date or the date of closing the transfer books, as the case may be. Failure to give such notice or any defect therein shall not affect the validity of any action taken in connection with the declaration or payment of any such dividend, or the issuance of any convertible or exchangeable securities, or subscription rights, options or warrants, or any proposed dissolution, liquidation, winding up or sale. 14. NOTICES. All notices, requests, consents and other communications hereunder shall be in writing and shall be deemed to have been duly made when delivered, or five days after being mailed by registered or certified mail, return receipt requested: (a) If to the registered Holders of the Representative's Warrant, to the address of such Holders as shown on the books of the Company; or (b) If to the Company to the address shown in the Underwriting Agreement or to such other address as the Company may designate by notice to the Holders. 15.
