State of Delaware. The Company has full power and



5



---

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).

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

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.

(d) Capitalization. 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). At December 31, 2009, there were 44,633,474 shares of Common Stock issued and 44,633,474 shares of Common Stock

(f) Legal Proceedings. There is no legal, administrative, regulatory
or governmental proceeding pending, or to the knowledge of the Company, threatened, to which the Company or any Subsidiary is a party or of which the business or property of the Company is subject, that is reasonably likely to have a Material
Adverse Effect. Neither the Company nor any of its Subsidiaries are subject to any injunction, judgment, decree or order of any court, regulatory body, administrative agency or other government body that is reasonably likely to have a Material
Adverse Effect.

(g) SEC Reports. The SEC Reports, including copies of all the exhibits included or
referenced therein, as of their respective dates (or, if amended or superseded by a filing prior to the date of this Agreement, then on the date of such amendment or superseding filing): (i) have been prepared and filed in compliance in all
material respects with the applicable requirements of the Exchange Act and the rules and regulations thereunder; and (ii) did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

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.

8



---

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). To the Companys knowledge, its use
of its Intellectual Property does not infringe the intellectual property rights of any third party which could reasonably be expected to have a Material Adverse Effect, individually or in the aggregate.

(l) Financial Statements. The financial statements of the Company and the related notes contained in the SEC
Reports present fairly and accurately in all material respects the financial position of the Company on a consolidated basis as of the dates therein indicated, and the consolidated results of its operations, cash flows and the changes in

in accordance with generally accepted accounting principles applied on a consistent basis at the times and throughout the periods therein specified, except that unaudited financial statements may not contain all footnotes required by generally
accepted accounting principles. The Company has no off-balance sheet arrangements. The Companys internal accounting controls and procedures are sufficient to cause the Company and each Subsidiary to prepare financial statements that comply in
all material respects with generally accepted accounting principles and the rules and regulations of the Commission on a consistent basis during the periods involved. Since December 31, 2008, nothing has been brought to the attention of the
Companys management that would result in any reportable condition relating to the Companys internal accounting procedures, weaknesses or controls that has not been reported as required by the Commission.

and its Subsidiaries have made or filed all federal, state and foreign income and all other tax returns, reports and declarations required by any jurisdiction to which they are subject and have paid or accrued all taxes and other governmental
assessments and charges that are material in amount, shown or determined to be due on such returns, reports and declarations.

that has had or is reasonably likely to have a Material Adverse Effect.

matters which are not reasonably likely to have a Material Adverse Effect and those contracts that are substantially or fully performed or expired by their terms, the contracts listed as exhibits to or described in the SEC Reports that are material
to the Company and all amendments thereto, are in full force and effect on the date hereof, and neither the Company nor, to the Companys knowledge, any other party to such contracts is in breach of or default under any of such contracts, which
breach or default is reasonably likely to result in a Material Adverse Effect. The Company maintains insurance in scope and amount which is reasonable and customary in the businesses in which the Company and the Subsidiaries are engaged.

(p) Investment Company. The Company is not an investment company or an affiliated person
of an investment company, within the meaning of the Investment

broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by the Transaction Agreements. The Purchasers shall have no obligation with respect to any fees
or with respect to any claims made by or on behalf of other Persons for fees of a type contemplated in this Section that may be due in connection with the transactions contemplated by the Transaction Agreements.

governmental agency responsible for the enforcement of such laws and regulations. There is no unfair labor practice charge or complaint against the Company or any of its Subsidiaries pending before any governmental agency or body or any strike,

The Purchaser has also carefully read and considered the Company SEC Reports, including, without limitation, the financial statements included therein. The Purchaser fully understands all of the risks related to the purchase of the Units. The
Purchaser understands that nothing in the SEC Reports, any Transaction Agreement, or any other materials presented to the Purchaser in connection with the purchase and sale of the Units constitutes legal, tax or investment advice. The Purchaser has
carefully considered and has discussed with the Purchasers professional legal, tax, accounting and financial advisors, to the extent the Purchaser has deemed necessary, the suitability of an investment in the Units for the Purchasers
particular tax and financial situation and has determined that the Units being purchased by the Purchaser are a suitable investment for the Purchaser. The Purchaser recognizes that an investment in the Units involves substantial risks, including the
possible loss of the entire amount of such investment. The Purchaser further recognizes that the Company has broad discretion concerning the use and application of the proceeds from the sale of the Units and exercise of the Warrants.

opportunity to request copies of any documents, records, and books pertaining to this investment and (ii) any such documents, records and books that the Purchaser requested have been made available for inspection by the Purchaser, the

answers from representatives of the Company or Persons acting on behalf of the Company concerning the Company, the offering contemplated by the Transaction Agreements and the Securities and all such questions have been answered to the full
satisfaction of the Purchaser.

(d) After examination of the SEC Reports and other information available, the
Purchaser is fully aware of the business, financial condition, risks associated with investment in the Units and the operating history relating to the Company, and therefore in subscribing for the purchase of the Units, the Purchaser is not relying
upon any information other than information contained in the SEC Reports or in the Transaction Agreements. The Purchaser acknowledges that it has independently evaluated the merits of the transactions contemplated by the Transaction Agreements, that

Units as a result of or subsequent to any advertisement, article, notice or other communication published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar, meeting or conference whose
attendees have been invited by any general solicitation or general advertising.

(f) If the Purchaser is a
natural Person, the Purchaser has reached the age of majority in the state in which the Purchaser resides. The Purchaser has adequate means of providing for the Purchasers current financial needs and contingencies, is able to bear the
substantial economic risks of an investment in the Securities for an indefinite period of time, has no need for liquidity in such investment and can afford a complete loss of such investment.

(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

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

with reasonable assurance that such Securities can be sold, assigned or transferred pursuant to Rule 144; (ii) any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if
Rule 144 is not applicable, any resale of the Securities under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may require compliance
with some other exemption under the Securities Act or the rules and regulations of the SEC thereunder; and (iii) neither the Company nor any other Person is under any obligation to register the Securities under the Securities Act or any state
securities laws or to comply with the terms and conditions of any exemption thereunder.

(m) The Purchaser
acknowledges that the Company will have the authority to issue shares of Common Stock, in excess of those being issued in connection herewith, and that the Company may issue additional shares of Common Stock from time to time. The issuance of

(n) The Purchaser understands that the Units are being offered and sold to it in reliance on specific exemptions from the
registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and the Purchasers compliance with, the representations, warranties, agreements,
acknowledgments and understandings of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire the Units.

(p) This Agreement has been duly and validly authorized, executed and delivered on behalf of the Purchaser and shall
constitute the legal, valid and binding obligations of such Purchaser enforceable against the Purchaser in accordance its terms.

(q) The execution, delivery and performance by the Purchaser of this Agreement and the consummation by the Purchaser of
the transactions contemplated hereby will not (i) result in a violation of the organizational documents of the Purchaser or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a
default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Purchaser is a party, or (iii) result in a violation of any law, rule, regulation,
order, judgment or decree (including federal and state securities laws) applicable to the Purchaser, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not, individually or in
the aggregate, reasonably be expected to have a material adverse effect on the ability of the Purchaser to perform its obligations hereunder. Assuming the accuracy of the representations and warranties, and the performance and satisfaction of the
covenants and agreements, of the Company pursuant to the Transaction Agreements, 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 Agreement by the Purchaser, other than such as have been made or obtained, and except for any filings required to be made under federal or state securities laws.

has, in connection with its purchase of the Units, complied with all applicable provisions of the Securities Act, including the rules and regulations promulgated by the SEC thereunder, and applicable state securities laws.

Person acting on its behalf or pursuant to any understanding with it will engage in any transactions in the securities of the Company (including Short Sales) prior to the time that the transactions contemplated by this Agreement are publicly
disclosed. Other than to other Persons party to this Agreement, such Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction).

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

4.1 Furnishing of Information. As long as any Purchaser owns any Securities, the Company covenants to timely file
(or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act and the rules and regulations of the Trading Market. As long as
any Purchaser owns any Securities, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information as is required
for the Purchasers to sell the Securities under Rule 144. The Company further covenants that it will take such further action as any holder of Securities may reasonably request, to the extent required from time to time to enable such Person to sell
such Securities without registration under the Securities Act within the requirements of the exemption provided by Rule 144.

4.2 Securities Laws Disclosure; Publicity. The Company shall, within the time period required by applicable law,
issue a Current Report on Form 8-K, disclosing the material terms of the transactions contemplated hereby. The Company may, in its discretion, attach the Transaction Agreements thereto. The Company may, in its discretion, issue a press release
concerning the transactions contemplated hereby. No Purchaser shall issue any press release or otherwise make any such public statement regarding the transactions contemplated hereby without the prior consent of the Company, except if such
disclosure is required by law, in which case the disclosing party shall promptly provide the Company with prior notice of such public statement or communication. The Company shall not need the prior consent of any Purchaser to issue the press
release with respect to the transactions contemplated hereby as set forth above in this Section 4.2. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any
filing with the Commission or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except (i) as required by federal securities law in connection with the filing of final Transaction Agreements
(including signature pages thereto) with the Commission and (ii) to the extent such disclosure is required by law or Trading Market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure
permitted under this subclause (ii).

4.3 Non-Public Information. Except with respect to the material
terms and conditions of the transactions contemplated by the Transaction Agreements, the Company covenants and agrees that neither it nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information
that constitutes material non-public information, unless prior thereto such Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that each Purchaser shall
be relying on the foregoing representations in effecting transactions in securities of the Company.

4.4
Use of Proceeds. The Company shall use the net proceeds from the sale of the Units hereunder for general corporate purposes, including without limitation working capital.

4.5 Indemnification of Purchasers. Subject to the provisions of this Section 4.5, the Company will indemnify,
defend and hold each Purchaser and its directors, officers,



15



---

shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other
title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners or employees (and any other
Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a Purchaser Party) harmless from any and all losses,
liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys fees and costs of investigation that any such Purchaser Party may suffer
or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Agreements or (b) any action instituted against a
Purchaser, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Purchaser, with respect to any of the transactions contemplated by the Transaction Agreements (unless such action is based
upon a breach of such Purchasers representations, warranties or covenants under the Transaction Agreements or any agreements or understandings such Purchaser may have with any such stockholder or any violations by the Purchaser of state or
federal securities laws or any conduct by such Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant
to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser
Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the
employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable
opinion of such separate counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more
than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (i) for any settlement by a Purchaser Party effected without the Companys prior written consent, which shall not be unreasonably
withheld or delayed or (ii) to the extent, but only to the extent, that a loss, claim, damage or liability is attributable to any Purchaser Partys breach of any of the representations, warranties, covenants or agreements made by such
Purchaser Party in this Agreement or in the other Transaction Agreements.

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.

4.7
Short Sales and Confidentiality After The Date Hereof. Each Purchaser severally and not jointly with the other Purchasers covenants that neither it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute
any Short Sales during the period



16



---

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). Notwithstanding the foregoing, no Purchaser makes any
representation, warranty or covenant hereby that it will not engage in Short Sales in the securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced as described in Section 4.2 and
any other material nonpublic information disclosed by or on behalf of the Company to such Purchaser is publicly announced. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate
portfolio managers manage separate portions of such Purchasers assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchasers assets, the
covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement.

4.8 Delivery of Securities After Closing. Subject to the receipt of all necessary information from each Purchaser,
the Company shall deliver, or cause to be delivered, the respective Securities purchased by each Purchaser at a Closing to such Purchaser within ten (10) Business Days of the Closing Date.

ARTICLE V.

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 sue for any breach by the
other party (or parties). Upon such termination, the terminating Purchaser shall be entitled to receive a full refund of such Purchasers Aggregate Purchase Price.

5.2 Fees and Expenses. Except as expressly set forth in the Transaction Agreements to the contrary, each party
shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. The
Company shall pay all transfer agent fees, stamp taxes and other taxes and duties levied in connection with the delivery of any Securities to the Purchasers.

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.

5.4 Notices. 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. The address for such notices and communications shall be as set forth on the signature pages attached hereto.

5.5 Amendments; Waivers. No provision of this Agreement may be waived or amended except in a written
instrument signed, in the case of an amendment, by the Company and Purchaser(s) holding 51% or more of the then outstanding Securities sold pursuant to this Agreement, or, in the case of a waiver, by the party against whom enforcement of any such
waived provision is sought. 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).

5.8 No Third-Party Beneficiaries. This Agreement is intended for the benefit
of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 4.5.

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



18



---

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



19



---

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



2



---

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



3



---

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



4



---

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



5



---

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.



6



---

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.
