Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investors. The Company and the Investor agree that the information set forth in the Investor Questionnaire and under the heading "Plan of Distribution" was the only information furnished by the Investor in writing expressly for use in connection with preparation of the Registration Statement on or prior to the date the Registration Statement was first declared effective by the SEC.

Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Investors. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 5(f)(2) with respect to any preliminary prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented. (3) Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 5(f) of notice of the commencement of any action (including any governmental action), such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 5(f), deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel reasonably satisfactory to the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding; provided further, however, that no indemnifying person shall be responsible for the fees and expenses of more than one separate counsel for all Indemnified Persons hereunder. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 5(f), except to the extent that the indemnifying party is prejudiced in its ability to defend such action. The indemnification required by this Section 5(f) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as such expense, loss, damage or liability is incurred and is due and payable. (g) Contribution. To the extent any indemnification by an indemnifying party as set forth in Section 5(f) above is applicable by its terms but is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 5(f) to the fullest extent permitted by law. In determining the amount of contribution to which the respective parties are entitled, there shall be considered the relative fault of each party, the parties' relative knowledge of and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission and any other equitable considerations appropriate under the circumstances; provided, however, that (a) no contribution shall be made under circumstances where the maker would not have been liable for indemnification under the fault standards set forth in Section 5(f), (b) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any other person who was not guilty of such fraudulent misrepresentation and (c) contribution by any seller of Registrable Securities shall be limited in amount to the proceeds received by such seller from the sale of such Registrable Securities. (h) Reports under 1934 Act. With a view to making available to the Investors the benefits of Rule 144, the Company agrees to: (1) furnish to each Investor so long as such Investor owns Registrable Securities, promptly upon request, (i) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company and (ii) such other -11- 12 information as may be necessary to permit the Investors to sell such securities pursuant to Rule 144 without registration; and (2) if at any time the Company is not required to file such reports with the SEC, use its best efforts to, upon the request of an Investor, make publicly available other information so long as is necessary to permit publication by bankers and dealers of quotations for the Common Stock and sales of the Registrable Securities in accordance with Rule 15c2-11 under the Exchange Act. Section 6. Exchange, Transfer or Assignment of Warrant. (a) If the Holder has received an opinion of counsel satisfactory to the Company that this Warrant may be freely sold or transferred without registration under the Act, as contemplated by Section 4 hereof, this Warrant, subject to subsection (b) of this Section 6, may be, at the option of the Holder, and upon presentation and surrender hereof to the Company at its principal office or to the Company's agent at its office, (i) exchanged for other Warrants of different denominations, entitling the Holder or Holders to purchase in the aggregate the same number of Warrant Shares at the Exercise Price or, (ii) if delivered together with a written notice specifying the denominations in which new Warrants are to be issued and signed by the Holder, divided or combined with other Warrants that carry the same rights. (b) If the Holder has received an opinion of counsel satisfactory to the Company that this Warrant may be freely sold or transferred without registration under the Act, as contemplated by Section 4 hereof, (x) this Warrant may be transferred and assigned, subject to subparagraph (y) of this Section 6(b), at the option of the Holder, upon surrender of this Warrant to the Company at its principal office or to the Company's agent at its office, with the warrant assignment form attached hereto as ANNEX V (the "Warrant Assignment Form") duly executed and accompanied by funds sufficient to pay any transfer tax, except that (y) no transfer or assignment of this Warrant may be made unless (i) such transfer or assignment is a Permitted Transfer or (ii) the Company consents in writing to such transfer or assignment, which consent may be withheld in its absolute discretion. The Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees named in such Warrant Assignment Form and, if the Holder's entire interest is not being transferred or assigned, in the name of the Holder; and this Warrant shall promptly be cancelled. (c) Any transfer or exchange of this Warrant shall be without charge to the Holder and any Warrant or Warrants issued pursuant to this Section 6 shall be dated the date hereof. Section 7. Lost, Mutilated or Missing Warrant. Upon receipt by the Company or its agent of evidence satisfactory to it of the loss, theft or destruction of this Warrant, and of satisfactory indemnification, and upon surrender and cancellation of this Warrant if mutilated, the Company or its agent shall execute and deliver a Warrant of like tenor and date in exchange for this Warrant. Section 8. Rights of the Holder. The Holder shall not, by virtue hereof, be entitled to any rights of a shareholder in the Company, either at law or in equity, and the rights of the Holder are limited to those expressed in this Warrant. Section 9. Anti-dilution. (a) If the Company shall fix or have fixed a record date at any time after the date hereof and before the expiration of the Exercise Period for: (i) Stock Dividends, Subdivisions, Combinations, Reclassifications, etc. (A) The declaration of a dividend or distribution on the Common Stock (or other securities -12- 13 deliverable hereunder) payable in shares of capital stock (whether shares of Common Stock or of capital stock of any other class), (B) the subdivision of shares of the Common Stock into a greater number of shares, (C) the combination of the Common Stock into a smaller number of shares or (D) the issuance of any shares of its capital stock by reclassification of the Common Stock in connection with a consolidation or merger with a subsidiary of the Company in which the Company is the continuing corporation, then, in any such event, the Holder shall be entitled to receive the aggregate number and kind of shares which, if the Warrant had been exercised immediately prior to such record date, the Holder would have been entitled to receive by virtue of such dividend, distribution, subdivision, combination or reclassification, and the Exercise Price shall be appropriately adjusted. Such adjustment shall be made successively whenever any event listed above shall occur. (ii) Issuance at Less Than Current Market Price. The issuance of rights, options or warrants to all holders of Common Stock (or other securities deliverable hereunder) entitling them to subscribe for or purchase Common Stock (or other securities deliverable hereunder) at a price per share or having a conversion or exercise price per share (including the amount paid, if any, for such rights, options or warrants) less than the Closing Price on such record date (excluding rights or warrants that are not immediately exercisable and for which provision is made for the Holder to receive comparable rights or warrants), then the number of Warrant Shares to be received hereunder after such record date shall be determined by multiplying the number of shares receivable hereunder immediately prior to such record date by a fraction, the denominator of which shall be the number of shares of Common Stock (or other securities deliverable hereunder) outstanding on such record date plus the number of shares of Common Stock (or other securities deliverable hereunder) that the aggregate offering price of the total number of shares so offered for subscription or purchase would purchase at such Closing Price, and the numerator of which shall be the number of shares of Common Stock (or other securities deliverable hereunder) outstanding on such record date plus the number of additional shares of Common Stock (or other securities deliverable hereunder) offered for subscription or purchase, and the Exercise Price shall be appropriately adjusted so that the aggregate purchase price of the Warrant Shares to be received hereunder after such record date is equal to the aggregate purchase price of the Warrant Shares receivable hereunder immediately prior to such record date. Shares of Common Stock owned by or held for the account of the Company or any subsidiary of the Company on such record date shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall become effective immediately after such record date. Such adjustment shall be made successively whenever any such event shall occur. If such rights, options or warrants are not so issued, the number of Warrant Shares receivable hereunder shall again be adjusted to be the number that would have been in effect had such record date not been fixed. On the expiration of such rights, options or warrants the number of Warrant Shares receivable hereunder shall be readjusted to be the number that would have obtained had the adjustment made upon the issuance of such rights, options or warrants been made upon the basis of the issuance of only the number of shares of Common Stock (or other securities deliverable hereunder) actually issued upon the exercise of such rights, options or warrants, provided, however, that if the Holder of this Warrant shall have exercised this Warrant prior to any such readjustment, the number of Warrant Shares that have been delivered or the number of Warrant Shares to be delivered shall not be subject to any readjustment. In any case in which this subsection (ii) shall require that an adjustment in the number of shares receivable hereunder or the Exercise Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event issuing to the Holder of any Warrant exercised after such record date the number of Warrant Shares, if any, issuable upon such exercise over and above the number of Warrant Shares, if any, issuable upon such exercise on the basis of the -13- 14 Exercise Price in effect prior to such adjustment; provided, however, that the Company shall deliver to such Holder a due bill or other appropriate instrument evidencing such Holder's right to receive such additional Warrant Shares upon the occurrence of the event requiring such adjustments. (iii) Distribution of Subscription Rights, Warrants, Evidences of Indebtedness or Assets. The making of a distribution to all holders of Common Stock (or other securities deliverable hereunder) (including any such distribution to be made in connection with a consolidation or merger in which the Company is to be the continuing corporation) of (A) any shares of capital stock of the Company (other than Common Stock), (B) subscription rights or warrants (excluding those for which adjustment is provided in subsection 9(a)(ii) above and excluding those that are not immediately exercisable and for which provision is made for the Holder to receive comparable subscription rights or warrants) or (C) evidences of its indebtedness or assets (excluding (x) dividends paid in or distributions of the Company's capital stock for which the number of Warrant Shares receivable hereunder shall have been adjusted pursuant to paragraph 9(a)(i) and (y) cash dividends or distributions payable out of earnings or surplus not in excess of 10% of the average Closing Price for the thirty trading days prior to the fifth day before the date of declaration multiplied by the number of outstanding shares of Common Stock) (any of the foregoing being hereinafter in this paragraph (iii) called the "Securities"), then in each such case (unless the Company elects to reserve shares or other units of such Securities for distribution to each Holder upon exercise of the Warrant so that, in addition to the shares of the Common Stock (or other securities deliverable hereunder) to which each Holder is entitled, each Holder will receive upon such exercise the amount and kind of such Securities which such Holder would have received if the Holder had, immediately prior to the record date for the distribution of the Securities, exercised the Warrant) the number of Warrant Shares receivable hereunder after such record date shall be determined by multiplying the number of Warrant Shares receivable hereunder immediately prior to such record date by a fraction, the denominator of which shall be the Closing Price on the trading day immediately prior to the date the Common Stock (or other securities deliverable hereunder) trades without the right to receive such Securities, less the fair market value (as determined in the reasonable judgment of the Board of Directors of the Company and described in a statement mailed by certified mail to the Holder) of the portion of the assets or evidences of indebtedness so to be distributed to a holder of one share of the Common Stock or of such subscription rights or warrants applicable to one share of the Common Stock, and the numerator of which shall be the Closing Price of the Common Stock on such trading date; and the Exercise Price shall be appropriately adjusted so that the aggregate purchase price of the Warrant Shares to be received hereunder after such record date is equal to the aggregate purchase price of the Warrant Shares receivable hereunder immediately prior to such record date. Such adjustment shall become effective immediately after such record date and shall be made successively whenever such a record date is fixed. If such distribution is not so made, the number of Warrant Shares receivable hereunder shall be readjusted to be the number that was in effect immediately prior to such record date. In the event that the Holder of this Warrant exercises this Warrant after an adjustment is made under this paragraph (iii) and prior to a readjustment under this paragraph (iii), the number of Warrant Shares that have been delivered or the number of Warrant Shares to be delivered shall not be subject to any readjustment. In any case in which this paragraph (iii) shall require that an adjustment in the number of Warrant Shares receivable hereunder or the Exercise Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event issuing to the Holder of any Warrant exercised after such record date the number of Warrant Shares, if any, issuable upon such exercise over and above the number of Warrant Shares, if any, issuable upon such exercise on the basis of the Exercise Price in effect prior to such adjustment; provided, -14- 15 however, that the Company shall deliver to such Holder a due bill or other appropriate instrument evidencing such Holder's right to receive such additional Warrant Shares upon the occurrence of the event requiring such adjustments. (b) Reorganization Event. (i) In case of any Reorganization Event the Company shall, as a condition precedent to the consummation of the transaction constituting, or announced as, such Reorganization Event, cause effective provisions to be made so that the Holder shall have the right immediately thereafter, by exercising this Warrant, to receive the aggregate amount and kind of shares of stock and other securities and property that were receivable upon such Reorganization Event by a holder of the number of shares of Common Stock that would have been received immediately prior to such Reorganization Event upon exercise of this Warrant. Any such provision shall include provision for adjustments in respect of such shares of stock and other securities and property that shall be as nearly equivalent as may be practicable to the adjustments provided for in Section 9(a). The foregoing provisions of this Section 9(b) shall similarly apply to successive Reorganization Events. (ii) The Company shall, at least twenty days before the Acceleration Date relating to any Reorganization Event (or if such Reorganization Event was beyond the control of the Company, and the Company did not have knowledge twenty days before such Acceleration Date, as soon as practicable thereafter), cause to be mailed to the Holder a notice describing in reasonable detail such Reorganization Event and informing the Holder of the date that the Exercise Period will (or did) commence and that the Holder may exercise this Warrant at any time during the Exercise Period. (c) Fractional Shares. No fractional shares of Common Stock (or other securities deliverable hereunder) or scrip shall be issued to any Holder in connection with the exercise of this Warrant. Instead of any fractional share of Common Stock (or other securities deliverable hereunder) that would otherwise be issuable to such Holder, the Company shall pay to such Holder a cash adjustment in respect of such fractional interest in an amount equal to such fractional interest multiplied by the Closing Price per share of Common Stock (or other securities deliverable hereunder) on the date of such exercise. (d) Carryover. Notwithstanding any other provision of this Section 9, no adjustment shall be made to the number of shares of Common Stock (or other securities deliverable hereunder) to be delivered to each Holder (or to the Exercise Price) if such adjustment would represent less than one percent of the number of shares to be so delivered, but any such adjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which, together with any adjustments so carried forward, shall amount to one percent or more of the number of shares to be so delivered. (e) Notices of Certain Events. If at any time after the date hereof and before the expiration of the Exercise Period: (i) the Company authorizes the issuance to all holders of its Common Stock of (A) rights or warrants to subscribe for or purchase shares of its Common Stock or (B) any other subscription rights or warrants; (ii) the Company authorizes the distribution to all holders of its Common Stock of evidences of its indebtedness or assets (other than cash dividends or distributions excluded from the operation of paragraph 9(a)(iii)); (iii) there shall be any capital reorganization of the Company or reclassification of the Common Stock (other than a change in par value of the Common Stock or an -15- 16 increase in the authorized capital stock of the Company not involving the issuance of any shares thereof) or any consolidation or merger to which the Company is a party (other than a consolidation or merger with a subsidiary in which the Company is the continuing corporation and that does not result in any reclassification or change in the Common Stock outstanding) or a conveyance or transfer of all or substantially all of the properties and assets of the Company: (iv) there shall be any voluntary or involuntary dissolution, liquidation or winding-up of the Company; or (v) there shall be any other event that would result in an adjustment pursuant to this Section 9 in the Exercise Price or the number of Warrant Shares that may be purchased upon the exercise hereof; the Company will cause to be mailed to the Holder, at least twenty days (or ten days in any case specified in the clauses (i) or (ii) above) before the applicable record or effective date hereinafter specified, a notice stating (A) the date as of which the holders of Common Stock of record entitled to receive any such rights, warrants or distributions is to be determined, or (B) the date on which any such reorganization, reclassification, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding-up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record will be entitled to exchange their shares of Common Stock for securities or other property, if any, deliverable upon such reorganization, reclassification, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding-up. (f) Failure to Give Notice. The failure to give the notice required by Section 9(e) hereof or any defect therein shall not affect the legality or validity of any distribution right, warrant, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding-up or the vote upon any such action. Section 10. Officers' Certificate. Whenever the number of Warrant Shares that may be purchased on exercise of this Warrant or the Exercise Price is adjusted as required by the provisions of Section 9 hereof, the Company will forthwith file in the custody of its Secretary or an Assistant Secretary at its principal office and at the office of its agent an officers' certificate showing the adjusted number of Warrant Shares that may be purchased at the Exercise Price on exercise of this Warrant and the adjusted Exercise Price determined as herein provided, setting forth in reasonable detail the facts requiring such adjustment and the manner of computing such adjustment. Each such officers' certificate shall be signed by the President, Chief Financial Officer or Treasurer of the Company and by the Secretary or an Assistant Secretary of the Company. Each such officers' certificate shall be made available at all reasonable times for inspection by the Holder. The Company shall, forthwith after each such adjustment, cause such certificate to be mailed to the Holder. Section 11. Availability of Information. In addition to the requirements of Section 5(h), the Company shall comply with all applicable public information reporting requirements of the SEC and applicable state securities laws to which it may from time to time be subject. The Company will also cooperate with each Holder of any Warrants and each holder of any Warrant Shares in supplying such information concerning the Company as may be necessary for such Holder or holder to complete and file any information reporting forms currently or hereafter required by the SEC as a condition to the availability of an exemption from the Act for the sales of any Warrants or Warrant Shares. Section 12. Warrant Register. The Company will register this Warrant in the Warrant Register in the name of the record holder to whom it has been distributed or assigned in -16- 17 accordance with the terms thereof. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof (notwithstanding any notation of ownership or other writing hereon made by anyone) for the purpose of any exercise hereof or any distribution to the Holder and for all other purposes, and the Company shall not be affected by any notice to the contrary.
