Upon the earlier of (i) registration for resale pursuant to the Registration Rights Agreement or (ii) Rule 144(k) becoming available, the Company shall (A) deliver to the transfer agent for the Common Stock (the "Transfer Agent") irrevocable instructions that the Transfer Agent shall reissue a certificate representing the Shares, the Conversion Shares and the Warrant Shares without legends upon receipt by such Transfer Agent of the legended certificates for such shares or the Notes and/or the Warrants (or any legended certificates previously issued for such Shares), together with either (1) a customary representation by the Investor that Rule 144(k) applies to the shares of Common Stock represented thereby or (2) a statement by the Investor that such Investor has sold the shares of Common Stock represented thereby in accordance with the Plan of Distribution contained in the Registration Statement therefor, and (B) cause its counsel to deliver to the Transfer Agent one or more blanket opinions to the effect that the removal of such legends in such circumstances may be effected under the 1933 Act.

(a) The Company shall take all action necessary to call an annual meeting of its stockholders (the "Stockholders Meeting"), which shall conclude not later than December 31, 2006 (the "Stockholders Meeting Deadline"), for the purpose of, among other things, seeking approval of the Company's stockholders for the following proposals (collectively, the "Proposals"): (i) the issuance and sale to the Investors of the Notes and applicable Warrant Shares pursuant to Nasdaq Marketplace Rule 4350(i) and (ii) the Amendment. In connection therewith, the Company will, in accordance with its customary practice for annual meetings, prepare and file with the SEC proxy materials (including a proxy 21 statement and form of proxy) for use at the Stockholders Meeting and, after receiving and promptly responding to any comments of the SEC thereon, shall mail such proxy materials to the stockholders of the Company. Each Investor shall furnish in writing to the Company such information relating to such Investor and its investment in the Company as the Company may reasonably request for inclusion in the Proxy Statement. The Company will comply with Section 14(a) of the 1934 Act and the rules promulgated thereunder in relation to any proxy statement (as amended or supplemented, the "Proxy Statement") and any form of proxy to be sent to the stockholders of the Company in connection with the Stockholders Meeting, and the Proxy Statement shall not, on the date that the Proxy Statement (or any amendment thereof or supplement thereto) is first mailed to stockholders or at the time of the Stockholders Meeting, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein not false or misleading, or omit to state any material fact necessary to correct any statement in any earlier communication with respect to the solicitation of proxies or the Stockholders Meeting which has become false or misleading. If the Company should discover at any time prior to the Stockholders Meeting, any event relating to the Company or any of its Subsidiaries or any of their respective affiliates, officers or directors that is required to be set forth in a supplement or amendment to the Proxy Statement, in addition to the Company's obligations under the 1934 Act, the Company will promptly inform the Investors thereof. (b) Subject to their fiduciary obligations under applicable law (as determined in good faith by the Company's Board of Directors after consultation with the Company's outside counsel), the Company's Board of Directors shall recommend to the Company's stockholders that the stockholders vote in favor of the Proposals (the "Company Board Recommendation") and take all commercially reasonable action (including, without limitation, the hiring of a proxy solicitation firm of nationally recognized standing) to solicit the approval of the stockholders for the Proposals unless the Board of Directors shall have modified, amended or withdrawn the Company Board Recommendation pursuant to the provisions of the immediately succeeding sentence. The Company covenants that the Board of Directors of the Company shall not modify, amend or withdraw the Company Board Recommendation unless the Board of Directors (after consultation with the Company's outside counsel) shall determine in the good faith exercise of its business judgment that maintaining the Company Board Recommendation would violate its fiduciary duty to the Company's stockholders. Whether or not the Company's Board of Directors modifies, amends or withdraws the Company Board Recommendation pursuant to the immediately preceding sentence, the Company shall in accordance with Section 146 of the Delaware General Corporation Law and the provisions of its Certificate of Incorporation and Bylaws, (i) take all action necessary to convene the Stockholders Meeting as promptly as practicable, but no later than the Stockholders Meeting Deadline, to consider and vote upon the approval of the Proposals and (ii) submit the Proposals at the Stockholders Meeting to the stockholders of the Company for their approval. (c) The Company shall file the Amendment with the Secretary of State of the State of Delaware no later than the close of business on the date the Proposals are approved by the Company's stockholders in accordance with this Section 7.9. 7.10 Delivery of Additional Warrants. On the Trading Day immediately following the date the Proposals are approved by the Company's stockholders in accordance 22 with Section 7.9, the Company shall issue and deliver to the Investors for no additional consideration the Additional Warrants in the amounts set forth opposite the Investors' names at the addresses set forth opposite such Investors' names on the signature pages hereto. 8.

The Company agrees to indemnify and hold harmless each Investor and its Affiliates and their respective directors, officers, employees and agents from and against any and all losses, claims, damages, liabilities and expenses (including without limitation reasonable attorney fees and disbursements and other expenses incurred in connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and the costs of enforcement thereof) (collectively, "Losses") to which such Person may become subject as a result of any breach of representation, warranty, covenant or agreement made by or to be performed on the part of the Company under the Transaction Documents, and will reimburse any such Person for all such amounts as they are incurred by such Person. 8.3 Conduct of Indemnification Proceedings. Promptly after receipt by any Person (the "Indemnified Person") of notice of any demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity may be sought pursuant to Section 8.2, such Indemnified Person shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all fees and expenses; provided, however, that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company is materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to the retention of such counsel; or (ii) in the reasonable judgment of counsel to such Indemnified Person representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Company shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled with such consent, or if there be a final judgment for the plaintiff, the Company shall indemnify and hold harmless such Indemnified Person from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment. Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, the Company shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding. 23 9. Miscellaneous. 9.1 Successors and Assigns. This Agreement may not be assigned by a party hereto without the prior written consent of the Company or the Investors, as applicable, provided, however, that an Investor may assign its rights and delegate its duties hereunder in whole or in part to an Affiliate or to a third party acquiring some or all of its Securities in a private transaction without the prior written consent of the Company or the other Investors, after notice duly given by such Investor to the Company provided, that no such assignment or obligation shall affect the obligations of such Investor hereunder.

All of the principal amount of this Note and any accrued and unpaid interest due hereon shall automatically and without any action on the part of the Holder convert into fully paid and nonassessable shares of Common Stock on the Trading Day immediately following the occurrence of a Forced Conversion Event (the "Automatic Conversion Date"). On the Automatic Conversion Date, this Note and all interest accrued thereon shall automatically and with no action on the part of the Holder convert into such number of fully paid and nonassessable shares of Common Stock as is obtained by: (i) adding (A) the principal amount of this Note and (B) the amount of any accrued but unpaid interest on this Note and (ii) dividing the result obtained pursuant to clause (i) above by the Conversion Price then in effect (such shares, the "Conversion Shares"). The Company shall provide prompt written notice of the Automatic Conversion Date to the Holder.

To the extent permitted by law, such conversion shall be deemed to have been effected, and the Conversion Price shall be determined, as of the close of business on the Automatic Conversion Date, and at such time, the rights of the Holder shall cease with respect to the Note being converted, and the Person or Persons in whose name or names any certificate or certificates for Conversion Shares shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the Conversion Shares represented thereby. A-7 (c) No fractional shares shall be issued upon any conversion of this Note into Common Stock. If any fractional share of Common Stock would, except for the provisions of the first sentence of this Section 4(c), be delivered upon such conversion, the Company, in lieu of delivering such fractional share, shall pay to the Holder an amount in cash equal to the Market Price of such fractional share of Common Stock. (d) If the Company shall, at any time or from time to time while this Note is outstanding, pay a dividend or make a distribution on its Common Stock in shares of Common Stock, subdivide its outstanding shares of Common Stock into a greater number of shares or combine its outstanding shares of Common Stock into a smaller number of shares or issue by reclassification of its outstanding shares of Common Stock any shares of its capital stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), then (i) the Conversion Price in effect immediately prior to the date on which such change shall become effective shall be adjusted by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such change and the denominator of which shall be the number of shares of Common Stock outstanding immediately after giving effect to such change and (ii) the number of Conversion Shares issuable upon conversion of this Note shall be adjusted by multiplying the number of Conversion Shares issuable upon conversion of this Note immediately prior to the date on which such change shall become effective by a fraction, the numerator of which is shall be the Conversion Price in effect immediately prior to the date on which such change shall become effective and the denominator of which shall be the Conversion Price in effect immediately after giving effect to such change, calculated in accordance with clause (i) above. Such adjustments shall be made successively whenever any event listed above shall occur. (e) If any capital reorganization, reclassification of the capital stock of the Company, consolidation or merger of the Company with another corporation in which the Company is not the survivor, or sale, transfer or other disposition of all or substantially all of the Company's assets to another Person shall be effected, then, as a condition of such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition, lawful and adequate provision shall be made whereby the Holder shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions herein specified and in lieu of the Conversion Shares immediately theretofore issuable upon conversion of this Note such shares of stock, securities or assets as would have been issuable or payable with respect to or in exchange for a number of Conversion Shares equal to the number of Conversion Shares immediately theretofore issuable upon conversion of this Note, had such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of the Holder to the end that the provisions hereof (including, without limitation, provision for adjustment of the Conversion Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares of stock, securities or assets thereafter deliverable upon the conversion hereof. The Company shall not effect any such consolidation, merger, sale, transfer or other disposition unless prior to or simultaneously with the consummation thereof the successor corporation (if other than the Company) resulting from such consolidation or merger, or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to deliver to the Holder, at the last address of the Holder A-8 appearing on the books of the Company, such shares of stock, securities or assets as, in accordance with the foregoing provisions, the Holder may be entitled to purchase, without regard to any conversion limitation specified in Section 4, and the other obligations under this Note. The provisions of this paragraph (e) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales, transfers or other dispositions. (f) In case the Company shall fix a payment date for the making of a distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness or assets (other than cash dividends or cash distributions payable out of consolidated earnings or earned surplus or dividends or distributions referred to in Section 4(d)), or subscription rights or warrants, the Conversion Price to be in effect after such payment date shall be determined by multiplying the Conversion Price in effect immediately prior to such payment date by a fraction, the numerator of which shall be the total number of shares of Common Stock outstanding multiplied by the Market Price of Common Stock immediately prior to such payment date, less the fair market value (as determined by the Board in good faith) of said assets or evidences of indebtedness so distributed, or of such subscription rights or warrants, and the denominator of which shall be the total number of shares of Common Stock outstanding multiplied by such Market Price immediately prior to such payment date. Such adjustment shall be made successively whenever such a payment date is fixed. (g) An adjustment to the Conversion Price shall become effective immediately after the payment date in the case of each dividend or distribution and immediately after the effective date of each other event which requires an adjustment. (h) In the event that, as a result of an adjustment made pursuant to this Section 4, the Holder shall become entitled to receive any shares of capital stock of the Company other than shares of Common Stock, the number of such other shares so receivable upon conversion of this Note shall be subject thereafter to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions contained in this Note. (i) Except as provided in Section 4(j) hereof, if and whenever the Company shall issue or sell, or is, in accordance with any of Sections 4(i)(i) through 4(i)(vii) hereof, deemed to have issued or sold, any Additional Shares of Common Stock (as defined below) for no consideration or for a consideration per share less than the Conversion Price in effect immediately prior to the time of such issuance or sale, then and in each such case (a "Trigger Issuance") the then-existing Conversion Price, shall be reduced, as of the close of business on the effective date of the Trigger Issuance, to a price determined as follows: Adjusted Conversion Price = (A x B) + D ----------- A+C where "A" equals the number of shares of Common Stock outstanding, including Additional Shares of Common Stock (as defined below) deemed to be issued hereunder, immediately preceding such Trigger Issuance; A-9 "B" equals the Conversion Price in effect immediately preceding such Trigger Issuance; "C" equals the number of Additional Shares of Common Stock issued or deemed issued hereunder as a result of the Trigger Issuance; and "D" equals the aggregate consideration, if any, received or deemed to be received by the Company upon such Trigger Issuance; provided, however, that in no event shall the Conversion Price after giving effect to such Trigger Issuance be greater than the Conversion Price in effect prior to such Trigger Issuance. For purposes of this subsection (i), "Additional Shares of Common Stock" shall mean all shares of Common Stock issued or sold by the Company or deemed to be issued or sold pursuant to this subsection (i), other than Excluded Issuances (as defined in subsection (j) hereof). For purposes of this Section 4(i), the following subsections (i)(i) to (i)(viii) shall also be applicable (subject, in each such case, to the provisions of Section 4(j) hereof): (i) In case at any time the Company shall in any manner grant (directly and not by assumption in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called "Options" and such convertible or exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount, if any, received or receivable by the Company as consideration for the granting of such Options, plus (y) the aggregate amount of additional consideration payable to the Company upon the exercise of all such Options, plus (z), in the case of such Options which relate to Convertible Securities, the aggregate amount of additional consideration, if any, payable upon the issuance or sale of such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Conversion Price immediately prior to the time of the granting of such Options, then the total number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued for such price per share as of the date of granting of such Options or the issuance of such Convertible Securities and thereafter shall be deemed to be outstanding for purposes of adjusting the Conversion Price. Except as otherwise provided in subsection 4(i)(iii), no adjustment of the Conversion Price shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities. A-10 (ii) In case the Company shall in any manner issue (directly and not by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount received or receivable by the Company as consideration for the issuance or sale of such Convertible Securities, plus (y) the aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange thereof, by (ii) the total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Conversion Price immediately prior to the time of such issuance or sale, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issuance or sale of such Convertible Securities and thereafter shall be deemed to be outstanding for purposes of adjusting the Conversion Price, provided that (a) except as otherwise provided in subsection 4(i)(iii), no adjustment of the Conversion Price shall be made upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities and (b) no further adjustment of the Conversion Price shall be made by reason of the issuance or sale of Convertible Securities upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the Conversion Price have been made pursuant to the other provisions of Section 4(i). (iii) Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in subsection 4(i)(i) hereof, the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in subsections 4(i)(i) or 4(i)(ii), or the rate at which Convertible Securities referred to in subsections 4(i)(i) or 4(i)(ii) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Conversion Price in effect at the time of such event shall forthwith be readjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold. On the termination of any Option for which any adjustment was made pursuant to this subsection 4(i) or any right to convert or exchange Convertible Securities for which any adjustment was made pursuant to this subsection 4(i) (including without limitation upon the redemption or purchase for consideration of such Convertible Securities by the Company), the Conversion Price then in effect hereunder shall forthwith be changed to the Conversion Price which would have been in effect at the time of such termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such termination, never been issued. (iv) Subject to the provisions of this Section 4(i), in case the Company shall declare a dividend or make any other distribution upon any stock of the Company (other than the Common Stock) payable in Common Stock, Options or Convertible Securities, then any Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration; provided, that if any adjustment is made to the Conversion Price as a result of a declaration of a A-11 dividend and such dividend is rescinded, the Conversion Price shall be appropriately readjusted to the Conversion Price in effect had such dividend not been declared. (v) In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the net amount received by the Company therefor, after deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Company in connection therewith. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company shall be deemed to be the fair value of such consideration as determined in good faith by the Board, after deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Company in connection therewith. In case any Options shall be issued in connection with the issuance and sale of other securities of the Company, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Company. If Common Stock, Options or Convertible Securities shall be issued or sold by the Company and, in connection therewith, other Options or Convertible Securities (the "Additional Rights") are issued, then the consideration received or deemed to be received by the Company shall be reduced by the fair market value of the Additional Rights (as determined using the Black-Scholes option pricing model or another method mutually agreed to by the Company and the Holder). The Board shall respond promptly, in writing, to an inquiry by the Holder as to the fair market value of the Additional Rights. In the event that the Board and the Holder are unable to agree upon the fair market value of the Additional Rights, the Company and the Holder shall jointly select an appraiser, who is experienced in such matters. The decision of such appraiser shall be final and conclusive, and the cost of such appraiser shall be borne evenly by the Company and the Holder. (vi) In case the Company shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issuance or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. (vii) The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company or any of its wholly-owned subsidiaries, and the disposition of any such shares (other than the cancellation or retirement thereof) shall be considered an issuance or sale of Common Stock for the purpose of this subsection (i). (viii) Notwithstanding any other provision in this subsection (i) to the contrary, if a reduction in the Conversion Price pursuant to this subsection (i) (other than as set forth in this clause (viii)) would require the Company to obtain stockholder approval of the transactions contemplated by the Purchase Agreement to be consummated on the Closing Date pursuant to Nasdaq Marketplace Rule 4350(i) and such stockholder approval has not been obtained, (i) the A-12 Conversion Price shall be reduced to the maximum extent that would not require stockholder approval under such Rule, and (ii) the Company shall use its commercially reasonable efforts to obtain such stockholder approval as soon as reasonably practicable, including by calling a special meeting of stockholders to vote on such Conversion Price adjustment. This provision shall not restrict the number of shares of Common Stock which a Holder may receive or beneficially own in order to determine the amount of securities or other consideration that such Holder may receive in the event of a transaction contemplated by Section 4 of this Note. (j) Anything herein to the contrary notwithstanding, the Company shall not be required to make any adjustment of the Conversion Price in the case of the issuance of (A) capital stock, Options or Convertible Securities issued to directors, officers, employees or consultants of the Company in connection with their service as directors of the Company, their employment by the Company or their retention as consultants by the Company pursuant to an equity compensation program approved by the Board of Directors of the Company or the compensation committee of the Board of Directors of the Company, (B) shares of Common Stock issued upon the conversion or exercise of Options or Convertible Securities issued prior to the date hereof, provided such securities are not amended after the date hereof to increase the number of shares of Common Stock issuable thereunder or to lower the exercise or conversion price thereof, (C) securities issued pursuant to the Purchase Agreement and securities issued upon the exercise or conversion of those securities, (D) shares of Common Stock issued or issuable by reason of a dividend, stock split or other distribution on shares of Common Stock (but only to the extent that such a dividend, split or distribution results in an adjustment in the Conversion Price pursuant to the other provisions of this Note) and (E) securities issued in connection with the Secured Notes (collectively, "Excluded Issuances"). (k) In case at any time: (i) the Company shall declare any dividend upon its Common Stock or any other class or series of capital stock of the Company payable in cash or stock or make any other distribution to the holders of its Common Stock or any such other class or series of capital stock; (ii) the Company shall offer for subscription pro rata to the holders of its Common Stock or any other class or series of capital stock of the Company any additional shares of stock of any class or other rights; or (iii) there shall be any capital reorganization or reclassification of the capital stock of the Company, any acquisition or a liquidation, dissolution or winding up of the Company; then, in any one or more of said cases, the Company shall give, by delivery in person or by certified or registered mail, return receipt requested, addressed to the Holder at the address of such Holder as shown on the books of the Company, (a) at least 20 Business Days' prior written notice of the date on which the books of the Company shall close or a record shall be taken for such dividend, distribution or subscription rights or for determining rights to vote in respect of any event set forth in clause (iii) of this Section 4(k) and (b) in the case of any event set forth in clause (iii) of this Section 4(k), at least 20 Business Days' prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause (a) shall also A-13 specify, in the case of any such dividend, distribution or subscription rights, the date on which the holders of Common Stock or such other class or series of capital stock shall be entitled thereto and such notice in accordance with the foregoing clause (b) shall also specify the date on which the holders of Common Stock and such other series or class of capital stock shall be entitled to exchange their Common Stock and other stock for securities or other property deliverable upon consummation of the applicable event set forth in clause (iii) of this Section 4(k). (l) Upon any adjustment of the Conversion Price, then and in each such case the Company shall give prompt written notice thereof, by delivery in person or by certified or registered mail, return receipt requested, addressed to the Holder at the address of such Holder as shown on the books of the Company, which notice shall state the Conversion Price resulting from such adjustment and setting forth in reasonable detail the method upon which such calculation is based. (m) From and after the effectiveness of the Amendment (as defined in the Purchase Agreement), the Company shall at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issuance upon conversion of this Note as herein provided, such number of shares of Common Stock as shall then be issuable upon the conversion of this Note. The Company covenants that all shares of Common Stock which shall be so issued shall be duly and validly issued and fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issue thereof, and, without limiting the generality of the foregoing, and that the Company will from time to time take all such action as may be requisite to assure that the par value per share of the Common Stock is at all times equal to or less than the Conversion Price in effect at the time. The Company shall take all such action as may be necessary to assure that all such shares of Common Stock may be so issued without violation of any applicable law or regulation, or of any requirement of any national securities exchange or trading market upon which the Common Stock may be listed. The Company shall not take any action which results in any adjustment of the Conversion Price if the total number of shares of Common Stock issued and issuable after such action upon conversion of this Note would exceed the total number of shares of Common Stock then authorized by the Company's Certificate of Incorporation. (n) The issuance of certificates for shares of Common Stock upon conversion of this Note shall be made without charge to the holders thereof for any issuance tax in respect thereof, provided 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 certificate in a name other than that of the Holder. (o) The Company will not at any time close its transfer books against the transfer, as applicable, of this Note or of any shares of Common Stock issued or issuable upon the conversion of this Note in any manner which interferes with the timely conversion of this Note, except as may otherwise be required to comply with applicable securities laws. A-14 5. Covenants.

(iii) The Company shall promptly notify the Holder of the occurrence of any Event of Default or any event which, with the giving of notice, the lapse of time or both would constitute an Event of Default, which notice shall include a written statement as to such occurrence, specifying the nature thereof and the action (if any) which is proposed to be taken with respect thereto. (iv) The Company shall promptly notify the Holder of any action, suit or proceeding at law or in equity or by or before any governmental instrumentality or other agency against the Company or any Subsidiary or to which the Company or any Subsidiary may be subject which alleges damages in excess of Two Hundred Fifty Thousand United States Dollars ($250,000).

(viii) The Company shall and shall cause each Subsidiary to comply with all laws, rules, regulations, orders, writs, judgments, injunctions, decrees or awards to which they may be subject except where the failure to so comply could not reasonably be expected to have a Material Adverse Effect.

SUBJECT TO THE PROVISIONS OF SECTION 10 HEREOF, THIS WARRANT SHALL BE VOID AFTER 5:00 P.M. EASTERN TIME ON NOVEMBER __, 2011 (THE "EXPIRATION DATE"). No. __________ ZILA, INC. WARRANT TO PURCHASE [_______] SHARES OF COMMON STOCK, PAR VALUE $0.001 PER SHARE For VALUE RECEIVED, ____________________ ("Warrantholder"), is entitled to purchase, subject to the provisions of this Warrant, from Zila, Inc., a Delaware corporation ("Company"), from and after the six month anniversary of the Closing Date (the "Initial Exercise Date") and at any time not later than 5:00 P.M., Eastern time, on the Expiration Date (as defined above), at an exercise price per share equal to $2.21 (the exercise price in effect being herein called the "Warrant Price"), ______ shares ("Warrant Shares") of the Company's Common Stock, par value $0.001 per share ("Common Stock"). The number of Warrant Shares purchasable upon exercise of this Warrant and the Warrant Price shall be subject to adjustment from time to time as described herein. Terms not otherwise defined herein have the respective meanings ascribed to them in the Purchase Agreement, dated November __, 2006 (the "Purchase Agreement"), among the Company, the initial holder of this Warrant and the other parties thereto. 1. Registration. The Company shall maintain books for the transfer and registration of the Warrant. Upon the initial issuance of this Warrant, the Company shall issue and register the Warrant in the name of the Warrantholder. 2. Transfers. As provided herein, this Warrant may be transferred only pursuant to a registration statement filed under the Securities Act of 1933, as amended (the "Securities Act"), or an exemption from such registration. Subject to such restrictions, the Company shall transfer this Warrant from time to time upon the books to be maintained by the Company for that purpose, upon surrender hereof for transfer, properly endorsed or accompanied by appropriate instructions for transfer and such other documents as may be reasonably required by the Company, including, if required by the Company, an opinion of its counsel to the effect that such transfer is exempt from the registration requirements of the Securities Act, to establish that such transfer is being made in accordance with the terms hereof, and a new Warrant shall be issued to the transferee and the surrendered Warrant shall be canceled by the Company. 3. Exercise of Warrant. Subject to the provisions hereof, the Warrantholder may exercise this Warrant, in whole or in part, at any time prior to its expiration upon surrender of the Warrant, together with delivery of a duly executed Warrant exercise form, in the form attached hereto as Appendix A (the "Exercise Agreement") and payment by cash, certified check or wire transfer of funds (or, in certain circumstances, by cashless exercise as provided below) of the aggregate Warrant Price for that number of Warrant Shares then being purchased, to the Company during normal business hours on any business day at the Company's principal executive offices (or such other office or agency of the Company as it may designate by notice to the Warrantholder). The Warrant Shares so purchased shall be deemed to be issued to the Warrantholder or the Warrantholder's designee, as the record owner of such shares, as of the close of business on the date on which this Warrant shall have been surrendered for exercise (or the date evidence of loss, theft or destruction thereof and security or indemnity satisfactory to the Company has been provided to the Company in connection with such exercise), the Warrant Price shall have been paid and the completed Exercise Agreement shall have been delivered. Certificates for the Warrant Shares so purchased shall be delivered to the Warrantholder within a reasonable time, not exceeding three (3) business days, after this Warrant shall have been so exercised. The certificates so delivered shall be in such denominations as may be requested by the Warrantholder and shall be registered in the name of the Warrantholder or such other name as shall be designated by the Warrantholder, as specified in the Exercise Agreement. If this Warrant shall have been exercised only in part, then, unless this Warrant has expired, the Company shall, at its expense, at the time of delivery of such certificates, deliver to the Warrantholder a new Warrant representing the right to purchase the number of shares with respect to which this Warrant shall not then have been exercised. As used herein, "business day" means a day, other than a Saturday or Sunday, on which banks in New York City are open for the general transaction of business. Each exercise hereof shall constitute the re-affirmation by the Warrantholder that the representations and warranties contained in Section 5 of the Purchase Agreement are true and correct in all material respects with respect to the Warrantholder as of the time of such exercise. 4. Compliance with the Securities Act of 1933. Except as provided in the Purchase Agreement, the Company may cause the legend set forth on the first page of this Warrant to be set forth on each Warrant, and a similar legend on any security issued or issuable upon exercise of this Warrant, unless counsel for the Company is of the opinion as to any such security that such legend is unnecessary. 5. Payment of Taxes. The Company will pay any documentary stamp taxes attributable to the initial issuance of Warrant Shares issuable upon the exercise of the Warrant; provided, however, that the Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificates for Warrant Shares in a name other than that of the Warrantholder in respect of which such shares are issued, and in such case, the Company shall not be required to issue or deliver any certificate for Warrant Shares or any Warrant until the person requesting the same has paid to the Company the amount of such tax or has established to the Company's reasonable satisfaction that such tax B-2 has been paid. The Warrantholder shall be responsible for income taxes due under federal, state or other law, if any such tax is due. 6. Mutilated or Missing Warrants. In case this Warrant shall be mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and substitution of and upon surrender and cancellation of the mutilated Warrant, or in lieu of and substitution for the Warrant lost, stolen or destroyed, a new Warrant of like tenor and for the purchase of a like number of Warrant Shares, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of the Warrant, and with respect to a lost, stolen or destroyed Warrant, reasonable indemnity or bond with respect thereto, if requested by the Company. 7. Reservation of Common Stock. The Company hereby represents and warrants that there have been reserved, and the Company shall at all applicable times keep reserved until issued (if necessary) as contemplated by this Section 7, out of the authorized and unissued shares of Common Stock, sufficient shares to provide for the exercise of the rights of purchase represented by this Warrant. The Company agrees that all Warrant Shares issued upon due exercise of the Warrant shall be, at the time of delivery of the certificates for such Warrant Shares, duly authorized, validly issued, fully paid and non-assessable shares of Common Stock of the Company. 8. Adjustments. Subject and pursuant to the provisions of this Section 8, the Warrant Price and number of Warrant Shares subject to this Warrant shall be subject to adjustment from time to time as set forth hereinafter. (a) If the Company shall, at any time or from time to time while this Warrant is outstanding, pay a dividend or make a distribution on its Common Stock in shares of Common Stock, subdivide its outstanding shares of Common Stock into a greater number of shares or combine its outstanding shares of Common Stock into a smaller number of shares or issue by reclassification of its outstanding shares of Common Stock any shares of its capital stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), then (i) the Warrant Price in effect immediately prior to the date on which such change shall become effective shall be adjusted by multiplying such Warrant Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such change and the denominator of which shall be the number of shares of Common Stock outstanding immediately after giving effect to such change and (ii) the number of Warrant Shares purchasable upon exercise of this Warrant shall be adjusted by multiplying the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior to the date on which such change shall become effective by a fraction, the numerator of which is shall be the Warrant Price in effect immediately prior to the date on which such change shall become effective and the denominator of which shall be the Warrant Price in effect immediately after giving effect to such change, calculated in accordance with clause (i) above. Such adjustments shall be made successively whenever any event listed above shall occur. (b) If any capital reorganization, reclassification of the capital stock of the Company, consolidation or merger of the Company with another corporation in which the Company is not the survivor, or sale, transfer or other disposition of all or substantially all of the B-3 Company's assets to another corporation shall be effected, then, as a condition of such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition, lawful and adequate provision shall be made whereby each Warrantholder shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions herein specified and in lieu of the Warrant Shares immediately theretofore issuable upon exercise of the Warrant, such shares of stock, securities or assets as would have been issuable or payable with respect to or in exchange for a number of Warrant Shares equal to the number of Warrant Shares immediately theretofore issuable upon exercise of the Warrant, had such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of each Warrantholder to the end that the provisions hereof (including, without limitation, provision for adjustment of the Warrant Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. The Company shall not effect any such consolidation, merger, sale, transfer or other disposition unless prior to or simultaneously with the consummation thereof the successor corporation (if other than the Company) resulting from such consolidation or merger, or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to deliver to the Warrantholder, at the last address of the Warrantholder appearing on the books of the Company, such shares of stock, securities or assets as, in accordance with the foregoing provisions, the Warrantholder may be entitled to purchase, and the other obligations under this Warrant. The provisions of this paragraph (b) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales, transfers or other dispositions. (c) In case the Company shall fix a payment date for the making of a distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness or assets (other than cash dividends or cash distributions payable out of consolidated earnings or earned surplus or dividends or distributions referred to in Section 8(a)), or subscription rights or warrants, the Warrant Price to be in effect after such payment date shall be determined by multiplying the Warrant Price in effect immediately prior to such payment date by a fraction, the numerator of which shall be the total number of shares of Common Stock outstanding multiplied by the Market Price (as defined below) per share of Common Stock immediately prior to such payment date, less the fair market value (as determined by the Company's Board of Directors in good faith) of said assets or evidences of indebtedness so distributed, or of such subscription rights or warrants, and the denominator of which shall be the total number of shares of Common Stock outstanding multiplied by such Market Price per share of Common Stock immediately prior to such payment date. "Market Price", as of a particular date (the "Valuation Date"), shall mean the following: (a) if the Common Stock is then listed on a national stock exchange, the closing sale price of one share of Common Stock on such exchange on the last Trading Day prior to the Valuation Date; (b) if the Common Stock is then quoted on the National Association of Securities Dealers, Inc. OTC Bulletin Board (the "Bulletin Board") or such similar quotation system or association, the closing sale price of one share of Common Stock on the Bulletin Board or such other quotation system or association on the last Trading Day prior to the Valuation Date or, if no such closing sale price is available, the average of the high bid and the low asked price quoted thereon on the last trading day prior to the Valuation Date; (c) if such security is then included in the "pink sheets," the closing sale price of B-4 one share of Common Stock on the "pink sheets" on the last Trading Day prior to the Valuation Date or, if no such closing sale price is available, the average of the high bid and the low ask price quoted on the "pink sheets" as of the end of the last Trading Day prior to the Valuation Date; or (d) if the Common Stock is not then listed on a national stock exchange or quoted on the Bulletin Board, the "pink sheets" or such other quotation system or association, the fair market value of one share of Common Stock as of the Valuation Date, as determined in good faith by the Board of Directors of the Company and the Warrantholder. If the Common Stock is not then listed on a national securities exchange or quoted on the Bulletin Board, the "pink sheets" or other quotation system or association, the Board of Directors of the Company shall respond promptly, in writing, to an inquiry by the Warrantholder prior to the exercise hereunder as to the fair market value of a share of Common Stock as determined by the Board of Directors of the Company. In the event that the Board of Directors of the Company and the Warrantholder are unable to agree upon the fair market value in respect of subpart (d) of this paragraph, the Company and the Warrantholder shall jointly select an appraiser, who is experienced in such matters. The decision of such appraiser shall be final and conclusive, and the cost of such appraiser shall be borne equally by the Company and the Warrantholder. Such adjustment shall be made successively whenever such a payment date is fixed. (d) An adjustment to the Warrant Price shall become effective immediately after the payment date in the case of each dividend or distribution and immediately after the effective date of each other event which requires an adjustment. (e) In the event that, as a result of an adjustment made pursuant to this Section 8, the Warrantholder shall become entitled to receive any shares of capital stock of the Company other than shares of Common Stock, the number of such other shares so receivable upon exercise of this Warrant shall be subject thereafter to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Warrant Shares contained in this Warrant. (f) Except as provided in subsection (g) hereof, if and whenever the Company shall issue or sell, or is, in accordance with any of subsections (f)(l) through (f)(7) hereof, deemed to have issued or sold, any Additional Shares of Common Stock (as defined below) for no consideration or for a consideration per share less than the Warrant Price in effect immediately prior to the time of such issuance or sale, then and in each such case (a "Trigger Issuance") the then-existing Warrant Price, shall be reduced, as of the close of business on the effective date of the Trigger Issuance, to a price determined as follows: Adjusted Warrant Price = (A x B) + D ----------- A+C where "A" equals the number of shares of Common Stock outstanding, including Additional Shares of Common Stock (as defined below) deemed to be issued hereunder, immediately preceding such Trigger Issuance; B-5 "B" equals the Warrant Price in effect immediately preceding such Trigger Issuance; "C" equals the number of Additional Shares of Common Stock issued or deemed issued hereunder as a result of the Trigger Issuance; and "D" equals the aggregate consideration, if any, received or deemed to be received by the Company upon such Trigger Issuance; provided, however, that in no event shall the Warrant Price after giving effect to such Trigger Issuance be greater than the Warrant Price in effect prior to such Trigger Issuance. For purposes of this subsection (f), "Additional Shares of Common Stock" shall mean all shares of Common Stock issued or sold by the Company or deemed to be issued or sold pursuant to this subsection (f), other than Excluded Issuances (as defined in subsection (g) hereof). For purposes of this subsection (f), the following subsections (f)(l) to (f)(8) shall also be applicable (subject, in each such case, to the provisions of Section 8(g) hereof): (f)(1) Issuance of Rights or Options. In case at any time the Company shall in any manner grant (directly and not by assumption in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called "Options" and such convertible or exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount, if any, received or receivable by the Company as consideration for the granting of such Options, plus (y) the aggregate amount of additional consideration payable to the Company upon the exercise of all such Options, plus (z), in the case of such Options which relate to Convertible Securities, the aggregate amount of additional consideration, if any, payable upon the issuance or sale of such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Warrant Price in effect immediately prior to the time of the granting of such Options, then the total number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued for such price per share as of the date of granting of such Options or the issuance of such Convertible Securities and thereafter shall be deemed to be outstanding for purposes of adjusting the Warrant Price. Except as otherwise provided in subsection 8(f)(3), no adjustment of the Warrant Price shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities. B-6 (f)(2) Issuance of Convertible Securities. In case the Company shall in any manner issue (directly and not by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount received or receivable by the Company as consideration for the issuance or sale of such Convertible Securities, plus (y) the aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange thereof, by (ii) the total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Warrant Price in effect immediately prior to the time of such issuance or sale, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issuance or sale of such Convertible Securities and thereafter shall be deemed to be outstanding for purposes of adjusting the Warrant Price, provided that (a) except as otherwise provided in subsection 8(f)(3), no adjustment of the Warrant Price shall be made upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities and (b) no further adjustment of the Warrant Price shall be made by reason of the issuance or sale of Convertible Securities upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the Warrant Price have been made pursuant to the other provisions of subsection 8(f). (f)(3) Change in Option Price or Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in subsection 8(f)(l) hereof, the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in subsections 8(f)(l) or 8(f)(2), or the rate at which Convertible Securities referred to in subsections 8(f)(l) or 8(f)(2) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Warrant Price in effect at the time of such event shall forthwith be readjusted to the Warrant Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold. On the termination of any Option for which any adjustment was made pursuant to this subsection 8(f) or any right to convert or exchange Convertible Securities for which any adjustment was made pursuant to this subsection 8(f) (including without limitation upon the redemption or purchase for consideration of such Convertible Securities by the Company), the Warrant Price then in effect hereunder shall forthwith be changed to the Warrant Price which would have been in effect at the time of such termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such termination, never been issued. B-7 (f)(4) Stock Dividends. Subject to the provisions of this Section 8(f), in case the Company shall declare a dividend or make any other distribution upon any stock of the Company (other than the Common Stock) payable in Common Stock, Options or Convertible Securities, then any Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration; provided, that if any adjustment is made to the Warrant Price as a result of a declaration of a dividend and such dividend is rescinded, the Warrant Price shall be appropriately readjusted to the Warrant Price in effect had such dividend not been declared. (f)(5) Consideration for Stock. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the net amount received by the Company therefor, after deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Company in connection therewith. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company shall be deemed to be the fair value of such consideration as determined in good faith by the Board of Directors of the Company, after deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Company in connection therewith. In case any Options shall be issued in connection with the issuance and sale of other securities of the Company, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Company. If Common Stock, Options or Convertible Securities shall be issued or sold by the Company and, in connection therewith, other Options or Convertible Securities (the "Additional Rights") are issued, then the consideration received or deemed to be received by the Company shall be reduced by the fair market value of the Additional Rights (as determined using the Black-Scholes option pricing model or another method mutually agreed to by the Company and the Warrantholder). The Board of Directors of the Company shall respond promptly, in writing, to an inquiry by the Warrantholder as to the fair market value of the Additional Rights. In the event that the Board of Directors of the Company and the Warrantholder are unable to agree upon the fair market value of the Additional Rights, the Company and the Warrantholder shall jointly select an appraiser, who is experienced in such matters. The decision of such appraiser shall be final and conclusive, and the cost of such appraiser shall be borne evenly by the Company and the Warrantholder. (f)(6) Record Date. In case the Company shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issuance or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. (f)(7) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company or any of its wholly-owned subsidiaries, and the disposition of any such shares (other than the B-8 cancellation or retirement thereof) shall be considered an issuance or sale of Common Stock for the purpose of this subsection (f). (f)(8) Nasdaq Limitation. Notwithstanding any other provision in Section 8(f) to the contrary, if a reduction in the Warrant Price pursuant to Section 8(f) (other than as set forth in this clause (f)(8)) would require the Company to obtain stockholder approval of the transactions contemplated by the Purchase Agreement to be consummated on the Closing Date pursuant to Nasdaq Marketplace Rule 4350(i) and such stockholder approval has not been obtained, (i) the Warrant Price shall be reduced to the maximum extent that would not require stockholder approval under such Rule, and (ii) the Company shall use its commercially reasonable efforts to obtain such stockholder approval as soon as reasonably practicable, including by calling a special meeting of stockholders to vote on such Warrant Price adjustment. This provision shall not restrict the number of shares of Common Stock which a Warrantholder may receive or beneficially own in order to determine the amount of securities or other consideration that such Holder may receive in the event of a transaction contemplated by Section 8 of this Warrant. (g) Anything herein to the contrary notwithstanding, the Company shall not be required to make any adjustment of the Warrant Price in the case of the issuance of (A) capital stock, Options or Convertible Securities issued to directors, officers, employees or consultants of the Company in connection with their service as directors of the Company, their employment by the Company or their retention as consultants by the Company pursuant to an equity compensation program approved by the Board of Directors of the Company or the compensation committee of the Board of Directors of the Company, (B) shares of Common Stock issued upon the conversion or exercise of Options or Convertible Securities issued prior to the date hereof, provided such securities are not amended after the date hereof to increase the number of shares of Common Stock issuable thereunder or to lower the exercise or conversion price thereof, (C) securities issued pursuant to the Purchase Agreement and securities issued upon the exercise or conversion of those securities, (D) shares of Common Stock issued or issuable by reason of a dividend, stock split or other distribution on shares of Common Stock (but only to the extent that such a dividend, split or distribution results in an adjustment in the Warrant Price pursuant to the other provisions of this Warrant) and (E) securities issued in connection with the Secured Notes (collectively, "Excluded Issuances"). (h) Upon any adjustment to the Warrant Price pursuant to Section 8(f) above, the number of Warrant Shares purchasable hereunder shall be adjusted by multiplying such number by a fraction, the numerator of which shall be the Warrant Price in effect immediately prior to such adjustment and the denominator of which shall be the Warrant Price in effect immediately thereafter. (i) To the extent permitted by applicable law and the listing requirements of any stock market or exchange on which the Common Stock is then listed, the Company from time to time may decrease the Warrant Price by any amount for any period of time if the period is at least twenty (20) days, the decrease is irrevocable during the period and the Board shall have made a determination that such decrease would be in the best interests of the Company, which determination shall be conclusive. Whenever the Warrant Price is decreased pursuant to the preceding sentence, the Company shall provide written notice thereof to the Warrantholder at B-9 least five (5) days prior to the date the decreased Warrant Price takes effect, and such notice shall state the decreased Warrant Price and the period during which it will be in effect. 9. Fractional Interest. The Company shall not be required to issue fractions of Warrant Shares upon the exercise of this Warrant. If any fractional share of Common Stock would, except for the provisions of the first sentence of this Section 9, be deliverable upon such exercise, the Company, in lieu of delivering such fractional share, shall pay to the exercising Warrantholder an amount in cash equal to the Market Price of such fractional share of Common Stock on the date of exercise. 10. Extension of Expiration Date. If the Company fails to cause any Registration Statement covering Registrable Securities (unless otherwise defined herein, capitalized terms are as defined in the Registration Rights Agreement relating to the Warrant Shares (the "Registration Rights Agreement")) to be declared effective prior to the applicable dates set forth therein, or if any of the events specified in Section 2(c)(ii) of the Registration Rights Agreement occurs, and the Blackout Period (whether alone, or in combination with any other Blackout Period) continues for more than 60 days in any 12 month period, or for more than a total of 90 days, then the Expiration Date of this Warrant shall be extended one day for each day beyond the 60-day or 90-day limits, as the case may be, that the Blackout Period continues. 11. Benefits. Nothing in this Warrant shall be construed to give any person, firm or corporation (other than the Company and the Warrantholder) any legal or equitable right, remedy or claim, it being agreed that this Warrant shall be for the sole and exclusive benefit of the Company and the Warrantholder. 12. Notices to Warrantholder. Upon the happening of any event requiring an adjustment of the Warrant Price, the Company shall promptly give written notice thereof to the Warrantholder at the address appearing in the records of the Company, stating the adjusted Warrant Price and the adjusted number of Warrant Shares resulting from such event and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Failure to give such notice to the Warrantholder or any defect therein shall not affect the legality or validity of the subject adjustment. 13. Identity of Transfer Agent. The Transfer Agent for the Common Stock is Computershare Trust Company. Upon the appointment of any subsequent transfer agent for the Common Stock or other shares of the Company's capital stock issuable upon the exercise of the rights of purchase represented by the Warrant, the Company will mail to the Warrantholder a statement setting forth the name and address of such transfer agent. 14. Notices. Unless otherwise provided, any notice required or permitted under this Warrant shall be given in writing and shall be deemed effectively given as hereinafter described (i) if given by personal delivery, then such notice shall be deemed given upon such delivery, (ii) if given by telex or facsimile, then such notice shall be deemed given upon receipt of confirmation of complete transmittal, (iii) if given by mail, then such notice shall be deemed given upon the earlier of (A) receipt of such notice by the recipient or (B) three days after such notice is deposited in first class mail, postage prepaid, and (iv) if given by an internationally recognized overnight air courier, then such notice shall be deemed given one business day after B-10 delivery to such carrier. All notices shall be addressed as follows: if to the Warrantholder, at its address as set forth in the Company's books and records and, if to the Company, at the address as follows, or at such other address as the Warrantholder or the Company may designate by ten days' advance written notice to the other: If to the Company: Zila, Inc. 5227 North 7th Street Phoenix, Arizona 85014-2800 Attention: Gary V. Klinefelter, Esq. Fax: (602) 230-8418 15. Registration Rights. The initial Warrantholder is entitled to the benefit of certain registration rights with respect to the shares of Common Stock issuable upon the exercise of this Warrant as provided in the Registration Rights Agreement, and any subsequent Warrantholder may be entitled to such rights. 16. Successors. All the covenants and provisions hereof by or for the benefit of the Warrantholder shall bind and inure to the benefit of its respective successors and assigns hereunder. 17. Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Warrant shall be governed by, and construed in accordance with, the internal laws of the State of New York, without reference to the choice of law provisions thereof. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in New York County and the United States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Warrant and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Warrant. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE COMPANY AND, BY ITS ACCEPTANCE HEREOF, THE WARRANTHOLDER HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS WARRANT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER. 18. Mandatory Exercise. Notwithstanding any other provision contained in this Warrant to the contrary, from and after the first anniversary of the Initial Exercise Date, in the event that the closing price per share of Common Stock equals or exceeds $5.00 (appropriately adjusted for any stock split, reverse stock split, stock dividend or other reclassification or B-11 combination of the Common Stock occurring after the date hereof) for twenty (20) consecutive trading days commencing after the Registration Statement (as defined in the Registration Rights Agreement) with respect to the shares of Common Stock issuable upon the exercise of this Warrant has been declared effective, the Company, upon thirty (30) days prior written notice (the "Notice Period") given to the Warrantholder within one business day immediately following the end of such twenty (20) trading day period, may demand that the Warrantholder exercise its cash exercise rights hereunder, and the Warrantholder must exercise its rights hereunder prior to the end of the Notice Period; provided that (i) the Company simultaneously gives a similar notice to all holders of Company Warrants (as defined below), (ii) all of the shares of Common Stock issuable hereunder either (A) are registered pursuant to an effective Registration Statement (as defined in the Registration Rights Agreement) which has not been suspended and for which no stop order is in effect, and pursuant to which the Warrantholder is able to sell such shares of Common Stock at all times during the Notice Period or (B) no longer constitute Registrable Securities (as defined in the Registration Rights Agreement) and (iii) this Warrant is fully exercisable for the full amount of Warrant Shares covered hereby. If such exercise is not made or if only a partial exercise is made, any and all rights to further exercise the Warrant shall cease upon the expiration of the Notice Period. Notwithstanding any such notice by the Company, the Warrantholder shall have the right to exercise this Warrant prior to the end of the Notice Period. 19. Cashless Exercise. Notwithstanding any other provision contained herein to the contrary, from and after the first anniversary of the Closing Date (as defined in the Purchase Agreement) and so long as the Company is required under the Registration Rights Agreement to have effected the registration of the Warrant Shares for resale to the public pursuant to a Registration Statement (as such term is defined in the Registration Rights Agreement), if the Warrant Shares may not be freely sold to the public as a result of the Company's failure to perform or satisfy its obligations under the Registration Rights Agreement, the Warrantholder may elect to receive, without the payment by the Warrantholder of the aggregate Warrant Price in respect of the shares of Common Stock to be acquired, shares of Common Stock of equal value to the value of this Warrant, or any specified portion hereof, by the surrender of this Warrant (or such portion of this Warrant being so exercised) together with a Net Issue Election Notice, in the form annexed hereto as Appendix B, duly executed, to the Company. Thereupon, the Company shall issue to the Warrantholder such number of fully paid, validly issued and nonassessable shares of Common Stock as is computed using the following formula: X = Y (A - B) --------- A where X = the number of shares of Common Stock to which the Warrantholder is entitled upon such cashless exercise; Y = the total number of shares of Common Stock covered by this Warrant for which the Warrantholder has surrendered purchase rights at such time for cashless exercise (including both shares to be issued to the Warrantholder and shares as to which the purchase rights are to be canceled as payment therefor); B-12 A = the "Market Price" of one share of Common Stock as at the date the net issue election is made; and B = the Warrant Price in effect under this Warrant at the time the net issue election is made. 20. Limitations on Exercise. Notwithstanding anything to the contrary contained herein, the number of Warrant Shares that may be acquired by the Warrantholder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the extent necessary to insure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by such Warrantholder and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Warrantholder's for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), does not exceed 9.999% of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. This provision shall not restrict the number of shares of Common Stock which a Holder may receive or beneficially own in order to determine the amount of securities or other consideration that such Holder may receive in the event of a transaction contemplated by Section 8 of this Warrant. This restriction may not be waived. 21. No Rights as Stockholder. Prior to the exercise of this Warrant, the Warrantholder shall not have or exercise any rights as a stockholder of the Company by virtue of its ownership of this Warrant. 22. Amendment; Waiver. This Warrant is one of a series of Warrants of like tenor issued by the Company pursuant to the Purchase Agreement and initially covering an aggregate of 5,403,000 shares of Common Stock (collectively, the "Company Warrants"). Any term of this Warrant may be amended or waived (including the adjustment provisions included in Section 8 of this Warrant) upon the written consent of the Company and the holders of Company Warrants representing at least 50% of the number of shares of Common Stock then subject to all outstanding Company Warrants (the "Majority Holders"); provided, that (x) any such amendment or waiver must apply to all Company Warrants; and (y) the number of Warrant Shares subject to this Warrant, the Warrant Price and the Expiration Date may not be amended, and the right to exercise this Warrant may not be altered or waived, without the written consent of the Warrantholder. 23. Section Headings. The section headings in this Warrant are for the convenience of the Company and the Warrantholder and in no way alter, modify, amend, limit or restrict the provisions hereof.

Terms not otherwise defined herein have the respective meanings ascribed to them in the Purchase Agreement, dated November __, 2006 (the "Purchase Agreement"), among the Company, the initial holder of this Warrant and the other parties thereto. Section 1. Registration. The Company shall maintain books for the transfer and registration of the Warrant. Upon the initial issuance of this Warrant, the Company shall issue and register the Warrant in the name of the Warrantholder. Section 2. Transfers. As provided herein, this Warrant may be transferred only pursuant to a registration statement filed under the Securities Act of 1933, as amended (the "Securities Act"), or an exemption from such registration. Subject to such restrictions, the Company shall transfer this Warrant from time to time upon the books to be maintained by the Company for that purpose, upon surrender hereof for transfer, properly endorsed or accompanied by appropriate instructions for transfer and such other documents as may be reasonably required by the Company, including, if required by the Company, an opinion of its counsel to the effect that such transfer is exempt from the registration requirements of the Securities Act, to establish that such transfer is being made in accordance with the terms hereof, and a new Warrant shall be issued to the transferee and the surrendered Warrant shall be canceled by the Company. Section 3. Exercise of Warrant. Subject to the provisions hereof, the Warrantholder may exercise this Warrant, in whole or in part, at any time prior to its expiration upon surrender of the Warrant, together with delivery of a duly executed Warrant exercise form, in the form attached hereto as Appendix A (the "Exercise Agreement") and payment by cash, certified check or wire transfer of funds (or, in certain circumstances, by cashless exercise as provided below) of the aggregate Warrant Price for that number of Warrant Shares then being purchased, to the Company during normal business hours on any business day at the Company's principal executive offices (or such other office or agency of the Company as it may designate by notice to the Warrantholder). The Warrant Shares so purchased shall be deemed to be issued to the Warrantholder or the Warrantholder's designee, as the record owner of such shares, as of the close of business on the date on which this Warrant shall have been surrendered for exercise (or the date evidence of loss, theft or destruction thereof and security or indemnity satisfactory to the Company has been provided to the Company in connection with such exercise), the Warrant Price shall have been paid and the completed Exercise Agreement shall have been delivered. Certificates for the Warrant Shares so purchased shall be delivered to the Warrantholder within a reasonable time, not exceeding three (3) business days, after this Warrant shall have been so exercised. The certificates so delivered shall be in such denominations as may be requested by the Warrantholder and shall be registered in the name of the Warrantholder or such other name as shall be designated by the Warrantholder, as specified in the Exercise Agreement. If this Warrant shall have been exercised only in part, then, unless this Warrant has expired, the Company shall, at its expense, at the time of delivery of such certificates, deliver to the Warrantholder a new Warrant representing the right to purchase the number of shares with respect to which this Warrant shall not then have been exercised. As used herein, "business day" means a day, other than a Saturday or Sunday, on which banks in New York City are open for the general transaction of business. Each exercise hereof shall constitute the re-affirmation by the Warrantholder that the representations and warranties contained in Section 5 of the Purchase Agreement are true and correct in all material respects with respect to the Warrantholder as of the time of such exercise. Section 4. Compliance with the Securities Act of 1933. Except as provided in the Purchase Agreement, the Company may cause the legend set forth on the first page of this Warrant to be set forth on each Warrant, and a similar legend on any security issued or issuable upon exercise of this Warrant, unless counsel for the Company is of the opinion as to any such security that such legend is unnecessary. Section 5. Payment of Taxes. The Company will pay any documentary stamp taxes attributable to the initial issuance of Warrant Shares issuable upon the exercise of the Warrant; provided, however, that the Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificates for Warrant Shares in a name other than that of the Warrantholder in respect of which such shares are issued, and in such case, the Company shall not be required to issue or deliver any certificate for Warrant Shares or any Warrant until the person requesting the same has paid to the Company the amount of such tax or has established to the Company's reasonable satisfaction that such tax C-2 has been paid. The Warrantholder shall be responsible for income taxes due under federal, state or other law, if any such tax is due. Section 6. Mutilated or Missing Warrants. In case this Warrant shall be mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and substitution of and upon surrender and cancellation of the mutilated Warrant, or in lieu of and substitution for the Warrant lost, stolen or destroyed, a new Warrant of like tenor and for the purchase of a like number of Warrant Shares, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of the Warrant, and with respect to a lost, stolen or destroyed Warrant, reasonable indemnity with respect thereto, if requested by the Company. Section 7. Reservation of Common Stock. The Company hereby represents and warrants that there have been reserved, and the Company shall at all applicable times keep reserved until issued (if necessary) as contemplated by this Section 7, out of the authorized and unissued shares of Common Stock, sufficient shares to provide for the exercise of the rights of purchase represented by this Warrant. The Company agrees that all Warrant Shares issued upon due exercise of the Warrant shall be, at the time of delivery of the certificates for such Warrant Shares, duly authorized, validly issued, fully paid and non-assessable shares of Common Stock of the Company. Section 8. Adjustments. Subject and pursuant to the provisions of this Section 8, the Warrant Price and number of Warrant Shares subject to this Warrant shall be subject to adjustment from time to time as set forth hereinafter. (a) If the Company shall, at any time or from time to time while this Warrant is outstanding, pay a dividend or make a distribution on its Common Stock in shares of Common Stock, subdivide its outstanding shares of Common Stock into a greater number of shares or combine its outstanding shares of Common Stock into a smaller number of shares or issue by reclassification of its outstanding shares of Common Stock any shares of its capital stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), then (i) the Warrant Price in effect immediately prior to the date on which such change shall become effective shall be adjusted by multiplying such Warrant Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such change and the denominator of which shall be the number of shares of Common Stock outstanding immediately after giving effect to such change and (ii) the number of Warrant Shares purchasable upon exercise of this Warrant shall be adjusted by multiplying the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior to the date on which such change shall become effective by a fraction, the numerator of which is shall be the Warrant Price in effect immediately prior to the date on which such change shall become effective and the denominator of which shall be the Warrant Price in effect immediately after giving effect to such change, calculated in accordance with clause (i) above. Such adjustments shall be made successively whenever any event listed above shall occur. (b) If any capital reorganization, reclassification of the capital stock of the Company, consolidation or merger of the Company with another corporation in which the Company is not the survivor, or sale, transfer or other disposition of all or substantially all of the C-3 Company's assets to another corporation shall be effected, then, as a condition of such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition, lawful and adequate provision shall be made whereby each Warrantholder shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions herein specified and in lieu of the Warrant Shares immediately theretofore issuable upon exercise of the Warrant, such shares of stock, securities or assets as would have been issuable or payable with respect to or in exchange for a number of Warrant Shares equal to the number of Warrant Shares immediately theretofore issuable upon exercise of the Warrant, had such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of each Warrantholder to the end that the provisions hereof (including, without limitation, provision for adjustment of the Warrant Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. The Company shall not effect any such consolidation, merger, sale, transfer or other disposition unless prior to or simultaneously with the consummation thereof the successor corporation (if other than the Company) resulting from such consolidation or merger, or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to deliver to the Warrantholder, at the last address of the Warrantholder appearing on the books of the Company, such shares of stock, securities or assets as, in accordance with the foregoing provisions, the Warrantholder may be entitled to purchase, and the other obligations under this Warrant. The provisions of this paragraph (b) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales, transfers or other dispositions. (c) In case the Company shall fix a payment date for the making of a distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness or assets (other than cash dividends or cash distributions payable out of consolidated earnings or earned surplus or dividends or distributions referred to in Section 8(a)), or subscription rights or warrants, the Warrant Price to be in effect after such payment date shall be determined by multiplying the Warrant Price in effect immediately prior to such payment date by a fraction, the numerator of which shall be the total number of shares of Common Stock outstanding multiplied by the Market Price (as defined below) per share of Common Stock immediately prior to such payment date, less the fair market value (as determined by the Company's Board of Directors in good faith) of said assets or evidences of indebtedness so distributed, or of such subscription rights or warrants, and the denominator of which shall be the total number of shares of Common Stock outstanding multiplied by such Market Price per share of Common Stock immediately prior to such payment date. "Market Price", as of a particular date (the "Valuation Date"), shall mean the following: (a) if the Common Stock is then listed on a national stock exchange, the closing sale price of one share of Common Stock on such exchange on the last Trading Day prior to the Valuation Date; (b) if the Common Stock is then quoted on the National Association of Securities Dealers, Inc. OTC Bulletin Board (the "Bulletin Board") or such similar quotation system or association, the closing sale price of one share of Common Stock on the Bulletin Board or such other quotation system or association on the last Trading Day prior to the Valuation Date or, if no such closing sale price is available, the average of the high bid and the low asked price quoted thereon on the last trading day prior to the Valuation Date; (c) if such security is then included in the "pink sheets," the closing sale price of C-4 one share of Common Stock on the "pink sheets" on the last Trading Day prior to the Valuation Date or, if no such closing sale price is available, the average of the high bid and the low ask price quoted on the "pink sheets" as of the end of the last Trading Day prior to the Valuation Date; or (d) if the Common Stock is not then listed on a national stock exchange or quoted on the Bulletin Board, the "pink sheets" or such other quotation system or association, the fair market value of one share of Common Stock as of the Valuation Date, as determined in good faith by the Board of Directors of the Company and the Warrantholder. If the Common Stock is not then listed on a national securities exchange or quoted on the Bulletin Board, the "pink sheets" or other quotation system or association, the Board of Directors of the Company shall respond promptly, in writing, to an inquiry by the Warrantholder prior to the exercise hereunder as to the fair market value of a share of Common Stock as determined by the Board of Directors of the Company. In the event that the Board of Directors of the Company and the Warrantholder are unable to agree upon the fair market value in respect of subpart (d) of this paragraph, the Company and the Warrantholder shall jointly select an appraiser, who is experienced in such matters. The decision of such appraiser shall be final and conclusive, and the cost of such appraiser shall be borne equally by the Company and the Warrantholder. Such adjustment shall be made successively whenever such a payment date is fixed. (d) An adjustment to the Warrant Price shall become effective immediately after the payment date in the case of each dividend or distribution and immediately after the effective date of each other event which requires an adjustment. (e) In the event that, as a result of an adjustment made pursuant to this Section 8, the Warrantholder shall become entitled to receive any shares of capital stock of the Company other than shares of Common Stock, the number of such other shares so receivable upon exercise of this Warrant shall be subject thereafter to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Warrant Shares contained in this Warrant. (f) Except as provided in subsection (g) hereof, if and whenever the Company shall issue or sell, or is, in accordance with any of subsections (f)(l) through (f)(7) hereof, deemed to have issued or sold, any Additional Shares of Common Stock (as defined below) for no consideration or for a consideration per share less than the Warrant Price in effect immediately prior to the time of such issuance or sale, then and in each such case (a "Trigger Issuance") the then-existing Warrant Price, shall be reduced, as of the close of business on the effective date of the Trigger Issuance, to a price determined as follows: (A x B) + D Adjusted Warrant Price = ----------- A + C where "A" equals the number of shares of Common Stock outstanding, including Additional Shares of Common Stock (as defined below) deemed to be issued hereunder, immediately preceding such Trigger Issuance; C-5 "B" equals the Warrant Price in effect immediately preceding such Trigger Issuance; "C" equals the number of Additional Shares of Common Stock issued or deemed issued hereunder as a result of the Trigger Issuance; and "D" equals the aggregate consideration, if any, received or deemed to be received by the Company upon such Trigger Issuance; provided, however, that in no event shall the Warrant Price after giving effect to such Trigger Issuance be greater than the Warrant Price in effect prior to such Trigger Issuance. For purposes of this subsection (f), "Additional Shares of Common Stock" shall mean all shares of Common Stock issued or sold by the Company or deemed to be issued or sold pursuant to this subsection (f), other than Excluded Issuances (as defined in subsection (g) hereof). For purposes of this subsection (f), the following subsections (f)(l) to (f)(8) shall also be applicable (subject, in each such case, to the provisions of Section 8(g) hereof): (f)(1) Issuance of Rights or Options. In case at any time the Company shall in any manner grant (directly and not by assumption in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called "Options" and such convertible or exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount, if any, received or receivable by the Company as consideration for the granting of such Options, plus (y) the aggregate amount of additional consideration payable to the Company upon the exercise of all such Options, plus (z), in the case of such Options which relate to Convertible Securities, the aggregate amount of additional consideration, if any, payable upon the issuance or sale of such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Warrant Price in effect immediately prior to the time of the granting of such Options, then the total number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued for such price per share as of the date of granting of such Options or the issuance of such Convertible Securities and thereafter shall be deemed to be outstanding for purposes of adjusting the Warrant Price. Except as otherwise provided in subsection 8(f)(3), no adjustment of the Warrant Price shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities. C-6 (f)(2) Issuance of Convertible Securities. In case the Company shall in any manner issue (directly and not by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount received or receivable by the Company as consideration for the issuance or sale of such Convertible Securities, plus (y) the aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange thereof, by (ii) the total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Warrant Price in effect immediately prior to the time of such issuance or sale, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issuance or sale of such Convertible Securities and thereafter shall be deemed to be outstanding for purposes of adjusting the Warrant Price, provided that (a) except as otherwise provided in subsection 8(f)(3), no adjustment of the Warrant Price shall be made upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities and (b) no further adjustment of the Warrant Price shall be made by reason of the issuance or sale of Convertible Securities upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the Warrant Price have been made pursuant to the other provisions of subsection 8(f). (f)(3) Change in Option Price or Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in subsection 8(f)(l) hereof, the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in subsections 8(f)(l) or 8(f)(2), or the rate at which Convertible Securities referred to in subsections 8(f)(l) or 8(f)(2) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Warrant Price in effect at the time of such event shall forthwith be readjusted to the Warrant Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold. On the termination of any Option for which any adjustment was made pursuant to this subsection 8(f) or any right to convert or exchange Convertible Securities for which any adjustment was made pursuant to this subsection 8(f) (including without limitation upon the redemption or purchase for consideration of such Convertible Securities by the Company), the Warrant Price then in effect hereunder shall forthwith be changed to the Warrant Price which would have been in effect at the time of such termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such termination, never been issued. C-7 (f)(4) Stock Dividends. Subject to the provisions of this Section 8(f), in case the Company shall declare a dividend or make any other distribution upon any stock of the Company (other than the Common Stock) payable in Common Stock, Options or Convertible Securities, then any Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration; provided, that if any adjustment is made to the Warrant Price as a result of a declaration of a dividend and such dividend is rescinded, the Warrant Price shall be appropriately readjusted to the Warrant Price in effect had such dividend not been declared. (f)(5) Consideration for Stock. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the net amount received by the Company therefor, after deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Company in connection therewith. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company shall be deemed to be the fair value of such consideration as determined in good faith by the Board of Directors of the Company, after deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Company in connection therewith. In case any Options shall be issued in connection with the issuance and sale of other securities of the Company, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Company. If Common Stock, Options or Convertible Securities shall be issued or sold by the Company and, in connection therewith, other Options or Convertible Securities (the "Additional Rights") are issued, then the consideration received or deemed to be received by the Company shall be reduced by the fair market value of the Additional Rights (as determined using the Black-Scholes option pricing model or another method mutually agreed to by the Company and the Warrantholder). The Board of Directors of the Company shall respond promptly, in writing, to an inquiry by the Warrantholder as to the fair market value of the Additional Rights. In the event that the Board of Directors of the Company and the Warrantholder are unable to agree upon the fair market value of the Additional Rights, the Company and the Warrantholder shall jointly select an appraiser, who is experienced in such matters. The decision of such appraiser shall be final and conclusive, and the cost of such appraiser shall be borne evenly by the Company and the Warrantholder. (f)(6) Record Date. In case the Company shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issuance or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. (f)(7) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company or any of its wholly-owned subsidiaries, and the disposition of any such shares (other than the C-8 cancellation or retirement thereof) shall be considered an issuance or sale of Common Stock for the purpose of this subsection (f). (f)(8) Nasdaq Limitation. Notwithstanding any other provision in Section 8(f) to the contrary, if a reduction in the Warrant Price pursuant to Section 8(f) (other than as set forth in this clause (f)(8)) would require the Company to obtain stockholder approval of the transactions contemplated by the Purchase Agreement to be consummated on the Closing Date pursuant to Nasdaq Marketplace Rule 4350(i) and such stockholder approval has not been obtained, (i) the Warrant Price shall be reduced to the maximum extent that would not require stockholder approval under such Rule, and (ii) the Company shall use its commercially reasonable efforts to obtain such stockholder approval as soon as reasonably practicable, including by calling a special meeting of stockholders to vote on such Warrant Price adjustment. This provision shall not restrict the number of shares of Common Stock which a Warrantholder may receive or beneficially own in order to determine the amount of securities or other consideration that such Holder may receive in the event of a transaction contemplated by Section 8 of this Warrant. (g) Anything herein to the contrary notwithstanding, the Company shall not be required to make any adjustment of the Warrant Price in the case of the issuance of (A) capital stock, Options or Convertible Securities issued to directors, officers, employees or consultants of the Company in connection with their service as directors of the Company, their employment by the Company or their retention as consultants by the Company pursuant to an equity compensation program approved by the Board of Directors of the Company or the compensation committee of the Board of Directors of the Company, (B) shares of Common Stock issued upon the conversion or exercise of Options or Convertible Securities issued prior to the date hereof, provided such securities are not amended after the date hereof to increase the number of shares of Common Stock issuable thereunder or to lower the exercise or conversion price thereof, (C) securities issued pursuant to the Purchase Agreement and securities issued upon the exercise or conversion of those securities, (D) shares of Common Stock issued or issuable by reason of a dividend, stock split or other distribution on shares of Common Stock (but only to the extent that such a dividend, split or distribution results in an adjustment in the Warrant Price pursuant to the other provisions of this Warrant) and (E) securities issued in connection with the Secured Notes (collectively, "Excluded Issuances"). (h) Upon any adjustment to the Warrant Price pursuant to Section 8(f) above, the number of Warrant Shares purchasable hereunder shall be adjusted by multiplying such number by a fraction, the numerator of which shall be the Warrant Price in effect immediately prior to such adjustment and the denominator of which shall be the Warrant Price in effect immediately thereafter. (i) To the extent permitted by applicable law and the listing requirements of any stock market or exchange on which the Common Stock is then listed, the Company from time to time may decrease the Warrant Price by any amount for any period of time if the period is at least twenty (20) days, the decrease is irrevocable during the period and the Board shall have made a determination that such decrease would be in the best interests of the Company, which determination shall be conclusive. Whenever the Warrant Price is decreased pursuant to the preceding sentence, the Company shall provide written notice thereof to the Warrantholder at C-9 least five (5) days prior to the date the decreased Warrant Price takes effect, and such notice shall state the decreased Warrant Price and the period during which it will be in effect. Section 9. Fractional Interest. The Company shall not be required to issue fractions of Warrant Shares upon the exercise of this Warrant. If any fractional share of Common Stock would, except for the provisions of the first sentence of this Section 9, be deliverable upon such exercise, the Company, in lieu of delivering such fractional share, shall pay to the exercising Warrantholder an amount in cash equal to the Market Price of such fractional share of Common Stock on the date of exercise. Section 10. Extension of Expiration Date. If the Company fails to cause any Registration Statement covering Registrable Securities (unless otherwise defined herein, capitalized terms are as defined in the Registration Rights Agreement relating to the Warrant Shares (the "Registration Rights Agreement")) to be declared effective prior to the applicable dates set forth therein, or if any of the events specified in Section 2(c)(ii) of the Registration Rights Agreement occurs, and the Blackout Period (whether alone, or in combination with any other Blackout Period) continues for more than 60 days in any 12 month period, or for more than a total of 90 days, then the Expiration Date of this Warrant shall be extended one day for each day beyond the 60-day or 90-day limits, as the case may be, that the Blackout Period continues. Section 11. Benefits. Nothing in this Warrant shall be construed to give any person, firm or corporation (other than the Company and the Warrantholder) any legal or equitable right, remedy or claim, it being agreed that this Warrant shall be for the sole and exclusive benefit of the Company and the Warrantholder. Section 12. Notices to Warrantholder. Upon the happening of any event requiring an adjustment of the Warrant Price, the Company shall promptly give written notice thereof to the Warrantholder at the address appearing in the records of the Company, stating the adjusted Warrant Price and the adjusted number of Warrant Shares resulting from such event and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Failure to give such notice to the Warrantholder or any defect therein shall not affect the legality or validity of the subject adjustment. Section 13. Identity of Transfer Agent. The Transfer Agent for the Common Stock is Computershare Trust Company. Upon the appointment of any subsequent transfer agent for the Common Stock or other shares of the Company's capital stock issuable upon the exercise of the rights of purchase represented by the Warrant, the Company will mail to the Warrantholder a statement setting forth the name and address of such transfer agent.

The initial Warrantholder is entitled to the benefit of certain registration rights with respect to the shares of Common Stock issuable upon the exercise of this Warrant as provided in the Registration Rights Agreement, and any subsequent Warrantholder may be entitled to such rights. Section 16. Successors. All the covenants and provisions hereof by or for the benefit of the Warrantholder shall bind and inure to the benefit of its respective successors and assigns hereunder. Section 17. Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Warrant shall be governed by, and construed in accordance with, the internal laws of the State of New York, without reference to the choice of law provisions thereof. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in New York County and the United States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Warrant and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Warrant. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE COMPANY AND, BY ITS ACCEPTANCE HEREOF, THE WARRANTHOLDER HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS WARRANT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER. Section 18. Mandatory Exercise. Notwithstanding any other provision contained in this Warrant to the contrary, from and after the first anniversary of the Automatic Conversion Date, in the event that the closing price per share of Common Stock equals or exceeds $5.00 (appropriately adjusted for any stock split, reverse stock split, stock dividend or other C-11 reclassification or combination of the Common Stock occurring after the date hereof) for twenty (20) consecutive trading days commencing after the Registration Statement (as defined in the Registration Rights Agreement) with respect to the shares of Common Stock issuable upon the exercise of this Warrant has been declared effective, the Company, upon thirty (30) days prior written notice (the "Notice Period") given to the Warrantholder within one business day immediately following the end of such twenty (20) trading day period, may demand that the Warrantholder exercise its cash exercise rights hereunder, and the Warrantholder must exercise its rights hereunder prior to the end of the Notice Period; provided that (i) the Company simultaneously gives a similar notice to all holders of Company Warrants (as defined below), (ii) all of the shares of Common Stock issuable hereunder either (A) are registered pursuant to an effective Registration Statement (as defined in the Registration Rights Agreement) which has not been suspended and for which no stop order is in effect, and pursuant to which the Warrantholder is able to sell such shares of Common Stock at all times during the Notice Period or (B) no longer constitute Registrable Securities (as defined in the Registration Rights Agreement) and (iii) this Warrant is fully exercisable for the full amount of Warrant Shares covered hereby. If such exercise is not made or if only a partial exercise is made, any and all rights to further exercise the Warrant shall cease upon the expiration of the Notice Period. Notwithstanding any such notice by the Company, the Warrantholder shall have the right to exercise this Warrant prior to the end of the Notice Period. Section 19. Cashless Exercise. Notwithstanding any other provision contained herein to the contrary, from and after the first anniversary of the Closing Date (as defined in the Purchase Agreement) and so long as the Company is required under the Registration Rights Agreement to have effected the registration of the Warrant Shares for resale to the public pursuant to a Registration Statement (as such term is defined in the Registration Rights Agreement), if the Warrant Shares may not be freely sold to the public as a result of the Company's failure to perform or satisfy its obligations under the Registration Rights Agreement, the Warrantholder may elect to receive, without the payment by the Warrantholder of the aggregate Warrant Price in respect of the shares of Common Stock to be acquired, shares of Common Stock of equal value to the value of this Warrant, or any specified portion hereof, by the surrender of this Warrant (or such portion of this Warrant being so exercised) together with a Net Issue Election Notice, in the form annexed hereto as Appendix B, duly executed, to the Company. Thereupon, the Company shall issue to the Warrantholder such number of fully paid, validly issued and nonassessable shares of Common Stock as is computed using the following formula: X = Y (A - B) --------- A where X = the number of shares of Common Stock to which the Warrantholder is entitled upon such cashless exercise; Y = the total number of shares of Common Stock covered by this Warrant for which the Warrantholder has surrendered purchase rights at such time for cashless C-12 exercise (including both shares to be issued to the Warrantholder and shares as to which the purchase rights are to be canceled as payment therefor); A = the "Market Price" of one share of Common Stock as at the date the net issue election is made; and B = the Warrant Price in effect under this Warrant at the time the net issue election is made. Section 20. Limitations on Exercise. Notwithstanding anything to the contrary contained herein, the number of Warrant Shares that may be acquired by the Warrantholder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the extent necessary to insure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by such Warrantholder and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Warrantholder's for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), does not exceed 9.999% of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. This provision shall not restrict the number of shares of Common Stock which a Holder may receive or beneficially own in order to determine the amount of securities or other consideration that such Holder may receive in the event of a transaction contemplated by Section 8 of this Warrant. This restriction may not be waived. Section 21. No Rights as Stockholder. Prior to the exercise of this Warrant, the Warrantholder shall not have or exercise any rights as a stockholder of the Company by virtue of its ownership of this Warrant. Section 22. Amendment; Waiver. This Warrant is one of a series of Warrants of like tenor issued by the Company pursuant to the Purchase Agreement and initially covering an aggregate of 3,105,000 shares of Common Stock (collectively, the "Company Warrants"). Any term of this Warrant may be amended or waived (including the adjustment provisions included in Section 8 of this Warrant) upon the written consent of the Company and the holders of Company Warrants representing at least 50% of the number of shares of Common Stock then subject to all outstanding Company Warrants (the "Majority Holders"); provided, that (x) any such amendment or waiver must apply to all Company Warrants; and (y) the number of Warrant Shares subject to this Warrant, the Warrant Price and the Expiration Date may not be amended, and the right to exercise this Warrant may not be altered or waived, without the written consent of the Warrantholder. Section 23. Section Headings.

Such Registration Statement also shall cover, to the extent allowable under the 1933 Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of additional shares of Common Stock resulting from stock splits, stock dividends or similar transactions with respect to the Additional Shares. Such Registration Statement shall not include any shares of Common Stock or other securities for the account of any other holder without the prior written consent of the Required Investors; provided, however, that the Company shall have the right to include (i) Secured Note Securities and (ii) the shares of Common Stock issued to Roth or which Roth may have the right to acquire as compensation for Roth's services to the Company in connection with the transaction contemplated by the Purchase Agreement and the Secured Note Agreement. The Registration Statement (and each amendment or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided in accordance with Section 3(c) to the Investors and/or their counsel prior to its filing or other submission. If a Registration Statement covering the Additional Shares is required to be filed under this Section 2(a)(ii) and is not filed with the SEC within thirty (30) days of the request of any Investor or upon the occurrence of any D-4 of the events specified in this Section 2(a)(ii), the Company will make pro rata payments to each Investor, as liquidated damages and not as a penalty, in an amount equal to 1.0% of the aggregate amount invested by such Investor with respect to the securities giving rise to the issuance of such Additional Shares for each 30-day period or pro rata for any portion thereof following the date by which such Registration Statement should have been filed for which no Registration Statement is filed with respect to the Additional Shares. Such payments shall constitute the Investors' exclusive monetary remedy for such events, but shall not affect the right of the Investors to seek injunctive relief. Such payments shall be made to each Investor in cash. (b) Expenses. The Company will pay all expenses associated with each registration, including filing and printing fees, the Company's counsel and accounting fees and expenses, costs associated with clearing the Registrable Securities for sale under applicable state securities laws, listing fees, fees and expenses of one counsel to the Investors and the Investors' reasonable expenses in connection with the registration, but excluding discounts, commissions, fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with respect to the Registrable Securities being sold.

Such payments shall constitute the Investors' exclusive monetary remedy for such events, but shall not affect the right of the Investors to seek injunctive relief. The amounts payable as liquidated damages pursuant to this paragraph shall be paid monthly within three (3) Business Days of the last day of each month following the commencement of the Blackout Period until the termination of the Blackout Period. (ii) For not more than twenty (20) consecutive days or for a total of not more than forty-five (45) days in any twelve (12) month period, the Company may delay the disclosure of material non-public information concerning the Company, by suspending the use of any Prospectus included in any registration contemplated by this Section containing such information, the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests of the Company (an "Allowed Delay"); provided, that the Company shall promptly (a) notify the Investors in writing of the existence of (but in no event, without the prior written consent of an Investor, shall the Company disclose to such Investor any of the facts or circumstances regarding) material non-public information giving rise to an Allowed Delay, (b) advise the Investors in writing to cease all sales under the Registration Statement until the end of the Allowed Delay and (c) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable.

Notwithstanding the other provisions of this Section 2, in no event shall the Company be liable for liquidated damages in excess of an aggregate of 24% of the aggregate purchase price paid by the Investors pursuant to the Purchase Agreement. 3.

(b) Indemnification by the Investors. Each Investor agrees, severally but not jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders and each person who controls the Company (within the meaning of the 1933 Act) against any losses, claims, damages, liabilities and expense (including reasonable attorney fees) resulting from (i) such Investor's failure to comply with the prospectus delivery requirements of the Securities Act at any time when the Company does not meet the conditions for use of Rule 172, has advised the Investor in writing that the Company D-10 does not meet such conditions and that therefore the Investor is required to deliver a Prospectus in connection with any sale or other disposition of Registrable Securities and has provided such Investor with a current Prospectus for such use, (ii) the use by an Investor of an outdated or defective Prospectus after the Company has notified the Investor that such Prospectus is outdated or defective and the use of a corrected or updated Prospectus would have avoided such losses, claims, damages, liabilities or expenses, and (iii) any untrue statement of a material fact or any omission of a material fact required to be stated in the Registration Statement or Prospectus or preliminary Prospectus or amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent that such untrue statement or omission is contained in any information furnished in writing by such Investor to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto. In no event shall the liability of an Investor be greater in amount than the dollar amount of the proceeds (net of all expense paid by such Investor in connection with any claim relating to this Section 6 and the amount of any damages such Investor has otherwise been required to pay by reason of such untrue statement or omission) received by such Investor upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation. (c) Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (a) the indemnifying party has agreed to pay such fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and provided, further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. (d) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party D-11 and the indemnifying party, as well as any other relevant equitable considerations. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 6 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation. 7.

By: ------------------------------------ Name: ---------------------------------- Title: --------------------------------- D-14 [NAME OF INVESTOR] By: ------------------------------------ Name: ---------------------------------- Title: --------------------------------- D-15 Exhibit A PLAN OF DISTRIBUTION The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices. The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein: - ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; - block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction; - purchases by a broker-dealer as principal and resale by the broker-dealer for its account; - an exchange distribution in accordance with the rules of the applicable exchange; - privately negotiated transactions; - short sales effected after the date the registration statement of which this Prospectus is a part is declared effective by the SEC; - through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise; - broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share; - a combination of any such methods of sale; and - any other method permitted by applicable law. The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as A-1 selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus. In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering. Upon any exercise of the warrants by payment of cash, however, we will receive the exercise price of the warrants. The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, provided that they meet the criteria and conform to the requirements of that rule. The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be "underwriters" within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are "underwriters" within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act. To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus. In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with. A-2 We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, to the extent applicable we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act. We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus. We have agreed with the selling stockholders to keep the registration statement of which this prospectus constitutes a part effective until the earlier of (1) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with the registration statement or (2) the date on which the shares may be sold pursuant to Rule 144(k) of the Securities Act.
