If the Expiration Date is a day on which banking institutions are authorized by law to close, then this Purchase Option may be exercised on the next succeeding day which is not such a day in accordance with the terms herein. During the period ending on the Expiration Date, the Company agrees not to take any action that would terminate the Purchase Option. This Purchase Option is initially exercisable at $22.50 per share of Common Stock; provided, however, that upon the occurrence of any of the events specified in Section 6 hereof, the rights granted by this Purchase Option, including the exercise price and the number of shares of Common Stock to be received upon such exercise, shall be adjusted as therein specified. The term "Exercise Price" shall mean the initial exercise price or the adjusted exercise price, depending on the context, of a share of Common Stock. 2. Exercise. 2.1 Exercise Form. In order to exercise this Purchase Option, the exercise form attached hereto must be duly executed and completed and delivered to the Company, together 1 with this Purchase Option and payment of the Exercise Price in cash or by certified check or official bank check for the Common Stock being purchased. If the subscription rights represented hereby shall not be exercised at or before 5:00 p.m., Eastern time, on the Expiration Date this Purchase Option shall become and be void without further force or effect, and all rights represented hereby shall cease and expire. 2.2 Legend. Each certificate for Common Stock purchased under this Purchase Option shall bear a legend as follows unless the sale by the Company to the Holder such Common Stock has been registered under the Securities Act of 1933, as amended ("Act"): "The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended ("Act") or applicable state law. The securities 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 registration under the Act and applicable state law." 3. Transfer. 3.1 General Restrictions. The registered Holder of this Purchase Option, by its acceptance hereof, agrees that it will not sell, transfer or assign or hypothecate this Purchase Option; provided, however, that sales, transfers or assignments may be made subject to compliance with or exemptions from applicable securities laws and pursuant to the terms of this Purchase Option. In order to make any permitted assignment, the Holder must deliver to the Company the assignment form attached hereto duly executed and completed, together with the Purchase Option and payment of all transfer taxes, if any, payable in connection therewith. The Company shall immediately transfer this Purchase Option on the books of the Company and shall execute and deliver a new Purchase Option or Purchase Options of like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate number of shares of Common Stock purchasable hereunder or such portion of such number as shall be contemplated by any such assignment. 3.2 Restrictions Imposed by the Act. This Purchase Option and the Common Stock underlying this Purchase Option shall not be transferred unless and until (i) the Company has received the opinion of counsel for the Holder that this Purchase Option or the Common Stock, as the case may be, may be transferred pursuant to an exemption from registration under the Act and applicable state law, the availability of which is established to the reasonable satisfaction of the Company (the Holder hereby agreeing that the opinion of Graubard Mollen & Miller shall be deemed satisfactory evidence of the availability of an exemption), or (ii) a registration statement relating to such Common Stock has been filed by the Company and declared effective by the Securities and Exchange Commission and is in compliance with applicable state law. 4. New Purchase Options to be Issued. 4.1 Partial Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase Option may be exercised or assigned in whole or in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase Option for cancellation, together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price and/or transfer tax, the Company shall cause to be delivered to the Holder without charge a new Purchase Option of like tenor to this Purchase Option in the name of the Holder 2 evidencing the right of the Holder to purchase the aggregate number of shares of Common Stock purchasable hereunder as to which this Purchase Option has not been exercised or assigned. 4.2 Lost Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this Purchase Option and of reasonably satisfactory indemnification, the Company shall execute and deliver a new Purchase Option of like tenor and date. Any such new Purchase Option executed and delivered as a result of such loss, theft, mutilation or destruction shall constitute a substitute contractual obligation on the part of the Company. 5. Registration Rights. 5.1 Demand Registration. 5.1.1 Grant of Right. The Company, upon written demand ("Initial Demand Notice") of the Holder of this Purchase Option and/or the underlying shares of Common Stock agrees to register under the Act, on one occasion, all or any portion of the Common Stock underlying this Purchase Option as requested by the Holder in the Initial Demand Notice ("Registrable Securities"). On such occasion, the Company will file a Registration Statement with the Securities and Exchange Commission ("SEC") covering the Registrable Securities within sixty days after receipt of the Initial Demand Notice and use its best efforts to have such registration statement declared effective promptly thereafter. The demand for registration may be made at any time during a period of four years beginning one year from the Commencement Date. The Company covenants and agrees to give written notice of its receipt of any Initial Demand Notice by the Holder to all other registered Holders of the Purchase Options and/or the Registrable Securities within ten days from the date of the receipt of any such Initial Demand Notice. 5.1.2 Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities with any SEC, but the Holders shall be responsible for and pay any and all underwriting commissions and any fees and the expenses of any legal counsel selected by the Holders to represent them in connection with any filing with the National Association of Securities Dealers, Inc. and sale of the Registrable Securities. The Company agrees to use its best efforts to cause the filing required herein to become effective under the Act promptly and to qualify or register the Registrable Securities in such States as are reasonably requested by the Holder; provided, however, that in no event shall the Company be required to register the Registrable Securities in a State in which such registration would cause (i) the Company to be obligated to register or license to do business in such State, or (ii) the principal stockholders of the Company to be obligated to escrow their shares of capital stock of the Company. The Company shall cause any registration statement filed pursuant to the demand rights granted under Section 5.1.1 to remain effective for a period of at least two years from the date that the Holders of the Registrable Securities covered by such registration statement are first given the opportunity to sell all of such securities. 5.2 "Piggy-Back" Registration. 5.2.1 Grant of Right. In addition to the demand right of registration, the Holder of this Purchase Option shall have the right for a period of six years commencing one year from the Commencement Date, to include the Registrable Securities as part of any other registration of securities filed under the Act by the Company (other than in connection with a transaction contemplated by Rule 145(a) promulgated under the Act or pursuant to Form S-8 or any 3 equivalent form) provided, however, that if, in the written opinion of the Company's managing underwriter or underwriters, if any, for such offering, the inclusion of the Registrable Securities, when added to the securities being registered by the Company or the selling stockholder(s), will exceed the maximum amount of the Company's securities which can be marketed (i) at a price reasonably related to their then current market value, or (ii) without materially and adversely affecting the entire offering, the Company shall nevertheless register all or any portion of the Registrable Securities required to be so registered but such Registrable Securities shall not be sold by the Holders until 180 days after the registration statement for such offering has become effective and provided further that, if any securities are registered for sale on behalf of other stockholders in such offering and such stockholders have not agreed to defer such sale until the expiration of such 180 day period, the number of securities to be sold by all stockholders in such public offering during such 180 day period shall be apportioned pro rata among all such selling stockholders, including all Holders of the Registrable Securities, according to the total amount of securities of the Company owned by said selling stockholders, including all Holders of the Registrable Securities. 5.2.2 Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities with the SEC, but the Holders shall be responsible for and pay any and all underwriting commissions and any fees and the expenses of any legal counsel selected by the Holders to represent them in connection with any filing with the National Association of Securities Dealers, Inc. and sale of the Registrable Securities. In the event of such a proposed registration, the Company shall furnish the then Holders of outstanding Registrable Securities with not less than thirty days written notice prior to the proposed date of filing of such registration statement with the SEC. Such notice to the Holders shall continue to be given for each registration statement filed by the Company until such time as all of the Registrable Securities have been sold by the Holder. The Holders of the Registrable Securities shall exercise the "piggy-back" rights provided for herein by giving written notice, within twenty days of the receipt of the Company's notice of its intention to file a registration statement. The Company shall cause any registration statement filed pursuant to the above "piggyback" rights to remain effective for at least two years from the date that the Holders of the Registrable Securities are first given the opportunity to sell all of such securities. 5.3 General Terms. 5.3.1 Indemnification by the Company. The Company agrees to indemnify and hold harmless the Holder(s) and each person, if any, who controls the Holder(s) within the meaning of the Securities Act and/or the Securities Exchange Act of 1934, as amended ("Exchange Act"), against any losses, claims, damages or liabilities, joint or several, to which the Holder(s) or such controlling person may become subject, under the Securities Act, Exchange Act or otherwise, 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 a material fact contained (A) in any registration statement for the Registrable Securities or (B) in any blue sky application or other document executed by the Company specifically for blue sky purposes or based upon any other written information furnished by the Company or on its behalf to any state or other jurisdiction in order to qualify any or all of the Registrable Securities under the securities laws thereof (any such application, document or information being hereinafter called a "Blue Sky Application"), or (ii) the omission or alleged omission by the Company to state in any registration statement for the Registrable Securities or in any Blue Sky Application a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and will reimburse the 4 Holder(s) and each such controlling person for any legal or other expenses reasonably incurred by the Holder(s) 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 or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information regarding the Holder(s) which is furnished to the Company by the Holder(s) for inclusion in any registration statement for the Registrable Securities or any such Blue Sky Application ("Non-Indemnity Events"). 5.3.2 Indemnification by the Holder(s). The Holder(s) agrees to indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of the Securities Act and/or the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which the Company or such controlling person may become subject, under the Securities Act, Exchange Act or otherwise insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any Non-Indemnity Event; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action provided that such loss, claim, damage or liability is found ultimately to arise out of or be based upon any Non-Indemnity Event. 5.3.3 Procedure. Promptly after receipt by an indemnified party under this Section 5 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 Section 5, notify in writing the indemnifying party of the commencement thereof; and the omission so to notify the indemnifying party will relieve the indemnifying party from any liability under this Section 5 as to the particular item for which indemnification is then being sought (if such failure materially prejudices the indemnifying party), but not from any other liability which it may have to any indemnified party. 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 therein, and to the extent that it may wish, jointly with any other indemnifying party, similarly notified, to assume the defense thereof, with counsel who shall be to the reasonable satisfaction of such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 5 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. Any such indemnifying party shall not be liable to any such indemnified party on account of any settlement of any claim or action effected without the consent of such indemnifying party, which consent shall not be unreasonably withheld. 5.3.4 Contribution. If the indemnification provided for in this Section 5 is unavailable to any indemnified party in respect to any losses, claims, damages, liabilities or expenses referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party, will contribute to the amount paid or payable by such indemnified party, as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand, and the Holder(s) on the other hand, from the Purchase Option and/or Registrable Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above, but also the relative fault of the Company on the one hand, and of the Holder(s) on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, 5 liabilities or expenses as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand, and the Holder(s) on the other hand, shall be deemed to be in the same proportion as the total proceeds from the Purchase Option and/or Registrable Securities received by the Company, bear to the total proceeds from the Purchase Option and/or Registrable Securities received by the Holder(s). The relative fault of the Company on the one hand, and the Holder(s) on the other hand, will be determined with reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Company, and its relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 5.3.5 Equitable Considerations. The Company and the Holder(s) agree that it would not be just and equitable if contribution pursuant to this Section 5 were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to in the immediately preceding paragraph. 5.3.6 Attorneys' Fees. The amount payable by a party under this Section 5 as a result of the losses, claims, damages, liabilities or expenses referred to above will be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim (including, without limitation, fees and disbursements of counsel incurred by an indemnified party in any action or proceeding between the indemnifying party and indemnified party or between the indemnified party and any third party or otherwise). 5.3.7 Exercise of Purchase Options. Nothing contained in this Purchase Option shall be construed as requiring the Holder to exercise its Purchase Options. 5.3.8 Exclusivity. The Company shall not permit the inclusion of any securities other than the Registrable Securities to be included in any registration statement filed pursuant to Section 5.1 hereof without the prior written consent of the Holders of the Registrable Securities. 5.3.9 Documents to be Delivered by Holder. Each Holder participating in any of the foregoing offerings shall furnish to the Company a completed and executed questionnaire provided by the Company requesting information customarily sought of selling securityholders. 6. Adjustments. 6.1 Adjustments to Exercise Price and Number of Securities. The Exercise Price and the number of shares of Common Stock underlying the Purchase Option shall be subject to adjustment from time to time as hereinafter set forth: 6.1.1 Stock Dividends - Recapitalization, Reclassification, Split-Ups. If after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock or by a split-up, recapitalization or reclassification of shares of Common Stock or other similar event, then, on the effective date thereof, the number of shares of Common Stock issuable on exercise of the Purchase Option shall be increased in proportion to such increase in outstanding shares. 6 6.1.2 Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 6.3, the number of outstanding shares of Common Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock or other similar event, then, upon the effective date thereof, the number of shares of Common Stock issuable on exercise of the Purchase Option shall be decreased in proportion to such decrease in outstanding shares. 6.1.3 Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of this Purchase Option is adjusted, as provided in this Section 6.1, the Exercise Price shall be adjusted (to the nearest cent) by multiplying such Exercise Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of this Purchase Option immediately prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter. 6.1.4 Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common Stock other than a change covered by Section 6.1.1 hereof or which solely affects the par value of such shares of Common Stock, or in the case of any merger or consolidation of the Company with or 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 reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Option shall have the right thereafter (until the expiration of the right of exercise of this Purchase Option) to receive upon the exercise hereof, for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or other transfer, by a Holder of the number of shares of Common Stock of the Company obtainable upon exercise of this Purchase Option immediately prior to such event; and if any reclassification also results in a change in shares of Common Stock covered by Section 6.1.1, then such adjustment shall be made pursuant to Sections 6.1.1, 6.1.3 and this Section 6.1.4. The provisions of this Section 6.1.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. 6.1.5 Changes in Form of Purchase Option. This form of Purchase Option need not be changed because of any change pursuant to this Section, and Purchase Options issued after such change may state the same Exercise Price and the same number of shares of Common Stock as are stated in the Purchase Options initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of new Purchase Options reflecting a required or permissive change shall not be deemed to waive any rights to a prior adjustment or the computation thereof. 6.2 Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of shares of Common Stock upon the exercise or of the Purchase Option upon its transfer, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up or down to the nearest whole number of Purchase Options, shares of Common Stock or other securities, properties or rights. 7 7. Reservation and Listing. 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 exercise of the Purchase Options, such number of shares of Common Stock or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Purchase Options and payment of the Exercise Price therefor, all shares of Common Stock and other securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any stockholder. As long as the Purchase Options shall be outstanding, the Company shall use its best efforts to cause all the shares of Common Stock issuable upon exercise of the Purchase Options to be listed (subject to official notice of issuance) on all securities exchanges (or, if applicable on Nasdaq) on which the Common Stock of the Company is then listed and/or quoted. 8. Certain Notice Requirements. 8.1 Holder's Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent or to receive notice as a stockholder 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 Purchase Options and their exercise, any of the events described in Section 8.2 shall occur, then, in one or more of said events, the Company shall give written notice of such event at least fifteen 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, conversion or exchange of 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 the closing of the transfer books, as the case may be. 8.2 Events Requiring Notice. The Company shall be required to give the notice described in this Section 8 upon one or more of the following events: (i) if 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 retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company, or (ii) 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 (iii) 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 shall be proposed. 8.3 Notice of Change in Exercise Price. The Company shall, promptly after an event requiring a change in the Exercise Price pursuant to Section 6 hereof, send notice to the Holders of such event and change ("Price Notice"). The Price Notice shall describe the event causing the change and the method of calculating same and shall be certified as being true and accurate by the Company's President and Chief Financial Officer. 8.4 Transmittal of Notices. All notices, requests, consents and other communications under this Purchase Option shall be in writing and shall be deemed to have been duly made on the date of delivery if delivered personally or sent by overnight courier, with acknowledgment of receipt to the party to which notice is given, or on the fifth day after mailing if mailed to the party to whom notice is to be given, by registered or certified mail, return receipt requested, postage prepaid and properly addressed as follows: (i) if to the registered Holder of the Purchase Option, 8 to the address of such Holder as shown on the books of the Company, or (ii) if to the Company, to its principal executive office. 9. Miscellaneous. 9.1 Amendments. The Company may from time to time supplement or amend this Purchase Option without the approval of any of the Holders in order to cure any ambiguity, to correct or supplement any provision contained herein which may be defective or inconsistent with any other provisions herein, or to make any other provisions in regard to matters or questions arising hereunder which the Company may deem necessary or desirable and which shall not adversely affect the interest of the Holders. All other modifications or amendments shall require the written consent of the party against whom enforcement of the modification or amendment is sought. 9.2 Headings. The headings contained herein are for the sole purpose of convenience of reference, and shall not in any way limit or affect the meaning or interpretation of any of the terms or provisions of this Purchase Option. 9.3 Entire Agreement. This Purchase Option (together with the other agreements and documents being delivered pursuant to or in connection with this Purchase Option) constitutes the entire agreement of the parties hereto with respect to the subject matter hereof, and supersedes all prior agreements and understandings of the parties, oral and written, with respect to the subject matter hereof. 9.4 Binding Effect. This Purchase Option shall inure solely to the benefit of and shall be binding upon, the Holder and the Company and their respective successors, legal representatives and assigns, and no other person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this Purchase Option or any provisions herein contained. 9.5 Governing Law; Submission to Jurisdiction. This Purchase Option shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflict of laws. The Company hereby agrees that any action, proceeding or claim against it arising out of, or relating in any way to this Purchase Option shall be brought and enforced in the courts of the State of New York or of the United States of America for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. Any process or summons to be served upon the Company may be served by transmitting a copy thereof by registered or certified mail, return receipt requested, postage prepaid, addressed to it at the address set forth in Section 8 hereof. Such mailing shall be deemed personal service and shall be legal and binding upon the Company in any action, proceeding or claim. The Company agrees that the prevailing party(ies) in any such action shall be entitled to recover from the other party(ies) all of its reasonable attor neys' fees and expenses relating to such action or proceeding and/or incurred in connection with the preparation therefor. 9.6 Waiver, Etc. The failure of the Company or the Holder to at any time enforce any of the provisions of this Purchase Option shall not be deemed or construed to be a waiver of any such provision, nor to in any way affect the validity of this Purchase Option or any provision hereof or the right of the Company or any Holder to thereafter enforce each and every provision 9 of this Purchase Option. No waiver of any breach, non-compliance or non-fulfillment of any of the provisions of this Purchase Option shall be effective unless set forth in a written instrument executed by the party or parties against whom or which enforcement of such waiver is sought; and no waiver of any such breach, non-compliance or non-fulfillment shall be construed or deemed to be a waiver of any other or subsequent breach, non-compliance or non-fulfillment. 9.7 Execution in Counterparts.
