(a) Organization. The Company is duly incorporated and validly existing in good standing under the laws of the State of Delaware. The Company has full power and

authority to own, operate and occupy its properties and to conduct its business as currently conducted and is registered or qualified to do business and in good standing in each jurisdiction in which it owns property or transacts business and where the failure to be so qualified would have a material adverse effect upon: (i) the Company and its Subsidiaries as a whole, (ii) the business, financial condition, properties, operations or assets of the Company and its Subsidiaries as a whole, or (iii) the Company’s ability to perform its obligations under the Transaction Agreements in all material respects (each, a “Material Adverse Effect”). No proceeding has been instituted, or to the Company’s knowledge, threatened, in any such jurisdiction revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification. Except as set forth in the SEC Reports, the Company does not currently own, directly or indirectly, a majority of the stock or other equity interests in any entity (each, a “Subsidiary”). Except for matters which are not reasonably likely to have a Material Adverse Effect, each Subsidiary of the Company has been duly incorporated, formed, or organized, and is validly existing, in good standing under the laws of the jurisdiction of its incorporation, formation, or organization, with full power and authority to own its properties and conduct its business as currently conducted. Except for matters which are not reasonably likely to have a Material Adverse Effect, all of the issued and outstanding capital stock of each Subsidiary of the Company has been duly authorized and validly issued and is fully paid and non-assessable and, except as disclosed in the SEC Reports, is owned of record by the Company, or a Subsidiary of the Company.

(b) Due Authorization. The Company has all requisite power and authority to execute, deliver and perform its obligations under the Transaction Agreements. The execution and delivery of the Transaction Agreements, and the consummation by the Company of the transactions contemplated thereby, have been duly authorized by all necessary corporate action. The Transaction Agreements that require execution by the Company have been validly executed and delivered by the Company and constitute legal, valid and binding agreements of the Company enforceable against the Company in accordance with their terms, except to the extent (i) rights to indemnity and contribution may be limited by state or federal securities laws or the public policy underlying such laws; (ii) such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and (iii) such enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(c) No Conflict or Default. The execution and delivery of the Transaction Agreements, the issuance and sale of the Securities to be sold by the Company under the Transaction Agreements, the fulfillment of the terms of the Transaction Agreements and the consummation of the transactions contemplated thereby will not: (A) result in a conflict with or constitute a violation of, or default (with the passage of time or otherwise) under, (i) any bond, debenture, note, loan agreement or other evidence of indebtedness, or any indenture, lease, mortgage, deed of trust or any other agreement or instrument to which the Company is a party or by which it is bound or to which any of the property or assets of the Company is subject, (ii) any stockholders agreement, voting agreement or similar agreement concerning the voting rights of stockholders, (iii) the Certificate of Incorporation, bylaws or other organizational documents of the Company, as amended, or (iv) with respect to the issuance and sale of the Securities,

assuming the accuracy of the representations and warranties and the performance and satisfaction of the covenants and agreements, of the Purchasers pursuant to the Transaction Agreements, any law, rule, ordinance, statute, regulation, or existing order of any court or governmental agency, or other authority binding upon the Company or the Company’s respective properties; or (B) result in the creation or imposition of any Lien upon any of the material assets of the Company or an acceleration of indebtedness pursuant to any obligation, agreement or condition contained in any material bond, debenture, note, loan agreement or other evidence of indebtedness, or any material indenture, lease, mortgage, deed of trust or any other agreement or instrument to which the Company is a party or by which it is bound or to which any of the property or assets of the Company is subject. No consent, approval, authorization or other order of, or registration, qualification or filing with, any regulatory body, administrative agency, or other governmental body is required for the execution and delivery of the Transaction Agreements by the Company and the valid issuance or sale of the Securities by the Company pursuant to the Transaction Agreements, other than such as have been made or obtained, and except for any filings required to be made under federal or state securities laws.

The authorized capital stock of the Company consists of 75,000,000 shares of Common Stock, par value $0.01 per share, and 1,000,000 shares of Preferred Stock, par value $0.01 per share (the “Preferred Stock”).

To the knowledge of the Company, it is not in violation of any law, rule, ordinance, statute, regulation or order of any court or governmental agency, arbitration panel or authority applicable to the Company, which violation, individually or in the aggregate, is reasonably likely to have a Material Adverse Effect. The Company is not in default (and there exists no condition which, with the passage of time or otherwise, would constitute a default) in the performance of any bond, debenture, note or any other evidence of indebtedness or any indenture, mortgage, deed of trust or any other material agreement or instrument to which the Company is a party or by which the Company is bound, which such default is reasonably likely to have a Material Adverse Effect.

(i) Governmental Permits, Etc. The Company and each of its Subsidiaries have all necessary franchises, licenses, certificates and other authorizations from any foreign, federal, state or local government or governmental agency, department or body that are currently necessary for the operation of the business of the Company and its Subsidiaries as currently conducted, except where the failure to currently possess such franchises, licenses, certificates and other authorizations is not reasonably likely to have a Material Adverse Effect.

(j) Good and Marketable Title to Property. The Company and its Subsidiaries have good and marketable title to, or a valid, subsisting and enforceable interest in, all real properties and all other properties and assets owned or leased by them that are material to the operation of the Company’s business.

right to use the same, free and clear of any claim or conflict with the rights of others (subject to the provisions of any applicable license agreement).

(g) The Purchaser has sufficient knowledge and experience in financial, tax and business matters to enable the Purchaser to utilize the information made available to the Purchaser in connection the transactions contemplated by the Transaction Agreements, to evaluate the merits and risks of an investment in the Securities and to make an informed investment decision with respect to an investment in the Securities on the terms described in the Transaction Agreements. The Purchaser has independently evaluated the merits and risks of its decision to purchase the Units, and the Purchaser confirms that it has not relied on the advice of the Company’s or any other Purchaser’s business and/or legal counsel in making such decision.

(h) The Purchaser will not sell or otherwise transfer the Securities without registration under the Securities Act and applicable state securities laws or an applicable exemption therefrom. The Purchaser acknowledges that neither the offer nor sale of the Units or any of the Securities has been registered under the Securities Act or under the securities laws of any state. The Purchaser represents and warrants that the Purchaser is acquiring the Securities for the Purchaser’s own account, for investment purposes and not with a view toward resale or distribution within the meaning of the Securities Act, except pursuant to sales registered or exempted under the Securities Act. The Purchaser is acquiring the Securities in the ordinary course of business. The Purchaser has not offered or sold the Securities being acquired nor does the Purchaser have any present intention of selling, distributing or otherwise disposing of such Securities either currently or after the passage of a fixed or determinable period of time or upon the occurrence or non-occurrence of any predetermined event or circumstances in violation of the Securities Act. The Purchaser is aware that (i) the Securities are not currently eligible for sale in reliance upon Rule 144 promulgated under the Securities Act and (ii) the Company has no obligation to register the Securities purchased hereunder.

4.6 Reservation of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue to reserve and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue Shares pursuant to this Agreement and Warrant Shares pursuant to any exercise of the Warrants.

commencing at the Discussion Time and ending at the time that the transactions contemplated by this Agreement are first publicly announced as described in Section 4.2. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement, or other information provided by or on behalf of the Company to such Purchaser, is publicly disclosed by the Company as described in Section 4.2 or otherwise, such Purchaser will maintain the confidentiality of all such disclosures (including the existence and terms of this transaction).

MISCELLANEOUS

5.1 Termination. This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder, by written notice to the other parties, if the Closing has not been consummated on or before April 30, 2010; provided, however, that no such termination will affect the right of any party to xxx for any breach by the other party (or parties).

5.3 Entire Agreement. The Transaction Agreements, together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules.

Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (a) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number set forth on the signature pages attached hereto prior to 5:30 p.m. (New York City time) on a Trading Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number set forth on the signature pages attached hereto on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any Trading Day, (c) the 2nd Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier service, or (d) upon actual receipt by the party to whom such notice is required to be given.

No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

5.6 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof.

5.7 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of each Purchaser (other than by merger).

5.9 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Agreements shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. The parties hereby waive all rights to a trial by jury.

5.10 Survival. The representations and warranties contained herein shall survive until the 18 month anniversary of the date hereof.

5.11 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective with respect to each Purchaser when counterparts have been signed by such Purchaser and the Company and delivered by each to the other, it being understood that both parties need

not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

5.12 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

5.13 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

5.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Agreements. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Agreements and hereby agrees to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

5.15 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or nonperformance of the obligations of any other Purchaser under any Transaction Agreement. Nothing contained herein or in any other Transaction Agreement, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Agreements. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other Transaction Agreements, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in their review and negotiation of the Transaction Agreements. Company has elected to provide all Purchasers with the same

terms and Transaction Agreements for the convenience of the Company and not because it was required or requested to do so by the Purchasers.

5.16 Construction. The parties agree that each of them and/or their respective counsel has reviewed and had an opportunity to revise the Transaction Agreements and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Agreements or any amendments hereto.

COMMON STOCK PURCHASE WARRANT

To Purchase Shares of Common Stock of

DARA BIOSCIENCES, INC.

Dated as of February 26, 2010

THIS COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, the holder (the “Holder”), is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the 6-month anniversary of the date hereof (the “Initial Exercise Date”) and on or prior to the close of business on the five year anniversary of the Initial Exercise Date (the “Termination Date”) but not thereafter, to subscribe for and purchase from DARA BioSciences, Inc., a Delaware corporation (the “Company”), up to [ TBD ] shares (the “Warrant Shares”) of Common Stock, par value $0.01 per share, of the Company (the “Common Stock”). The purchase price of one share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).

Section 1. Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement (the “Purchase Agreement”), dated as of February 26, 2010, among the Company and the purchasers signatory thereto.

Section 2. Exercise.

a) Exercise of Warrant. Subject to compliance with applicable securities laws, exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of a duly executed facsimile copy of the Notice of Exercise Form annexed hereto (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of such Holder appearing on the books of the

Company); provided, however, within five Trading Days of the date said Notice of Exercise is delivered to the Company, if this Warrant is exercised in full, the Holder shall have surrendered this Warrant to the Company and the Company shall have received payment of the aggregate Exercise Price of the Warrant Shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise Form within two (2) Business Days of receipt of such notice. In the event of any dispute or discrepancy, the records of the Company shall be controlling and determinative in the absence of manifest error. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

b) Exercise Price. The per share exercise price of the Common Stock under this Warrant shall be $0.47, subject to adjustment hereunder (the “Exercise Price”).

c) Mechanics of Exercise.

i. Authorization of Warrant Shares. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

ii. Delivery of Certificates Upon Exercise. Certificates for shares purchased hereunder shall be transmitted to the Holder by physical delivery to the address specified by the Holder in the Notice of Exercise within ten (10) Business Days from the delivery to the Company of the Notice of Exercise Form, surrender of this Warrant (if required) and payment of the aggregate Exercise Price as set forth above (“Warrant Share Delivery Date”). This Warrant shall be deemed to have been exercised on the date the Exercise Price is received by the Company. The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised by payment to the Company of the Exercise Price.

iii. Restrictive Legend. The Holder understands that unless the issuance of the Warrant Shares shall have been registered or otherwise may be sold pursuant to Rule 144 under the Securities Act or another exemption from registration under the Securities Act without any restriction as to the number of securities as of a particular date that can then

be immediately sold, the Warrant Shares shall bear a restrictive legend in substantially the form described in the Purchase Agreement (and a stop-transfer order may be placed against transfer of the certificates for such securities).

iv. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

v. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price.

Section 3. Certain Adjustments.

a) Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (A) pays a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company pursuant to this Warrant or the other Warrants), (B) subdivides outstanding shares of Common Stock into a larger number of shares, (C) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (D) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

b) Fundamental Transaction. If, at any time while this Warrant is outstanding, (A) the Company effects any merger or consolidation of the Company with or into another Person, (B) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (C) any tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, or (D) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (each “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable

upon such exercise immediately prior to the occurrence of such Fundamental Transaction, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and/or any other consideration, including cash (the “Alternate Consideration”), receivable as a result of such merger, consolidation or disposition of assets by a Holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such event. For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new warrant consistent with the foregoing provisions and evidencing the Holder’s right to exercise such warrant into Alternate Consideration.

c) Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

d) Notice to Holders. Whenever the Exercise Price is adjusted pursuant to this Section 3, the Company shall promptly mail to each Holder a notice setting forth the Exercise Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

Section 4. Transfer of Warrant.

a) Transferability. This Warrant and all rights hereunder are transferable in accordance, and only in accordance, with applicable securities laws and the Securities Purchase Agreement, in whole or in part, upon surrender of this Warrant at the principal office of the Company, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. A Warrant, if properly assigned, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

b) New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice

specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice.

c) Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

Section 5. Miscellaneous.

a) Title to Warrant. Prior to the Termination Date and subject to compliance with applicable laws and Section 4 of this Warrant, this Warrant and all rights hereunder are transferable, in whole or in part, at the office or agency of the Company by the Holder in person or by duly authorized attorney, upon surrender of this Warrant together with the Assignment Form annexed hereto properly endorsed.

b) No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights or other rights as a stockholder of the Company prior to the exercise hereof. Upon the surrender of this Warrant and the payment of the aggregate Exercise Price (or by means of a cashless exercise), the Warrant Shares so purchased shall be and be deemed to be issued to such Holder as the record owner of such shares as of the close of business on the later of the date of such surrender or payment.

c) Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

d) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall be a Saturday, Sunday or a legal holiday, then such action may be taken or such right may be exercised on the next succeeding day not a Saturday, Sunday or legal holiday.

e) Authorized Shares.

The Company covenants that during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the

necessary certificates for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation.

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (b) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

f) Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the provisions of the Purchase Agreement.

g) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant will not be registered and will have restrictions upon resale imposed by state and federal securities laws.

h) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice Holder’s rights, powers or remedies, notwithstanding the fact that all rights hereunder terminate on the Termination Date. If the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

i) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in accordance with the notice provisions of the Purchase Agreement.

j) Limitation of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant or purchase Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

k) Remedies. Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.

l) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant and shall be enforceable by any such Holder or holder of Warrant Shares.

m) Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

n) Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

o) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by its officer thereunto duly authorized.
