 REPRESENTATIONS AND WARRANTIES

  
 3.1 Representations and Warranties of the Company.
Except as set forth under the corresponding section of the Disclosure Schedules delivered concurrently herewith, the Company hereby makes the following representations and warranties as of the date hereof and as of the Closing Date to each
Purchaser: 
  
 (a) Subsidiaries. The
Company has no direct or indirect subsidiaries except as set forth in an SEC Report, namely the Annual Report on Form 10-K for the year ended December 31, 2003 and filed March 30, 2004 (the “2004 Form 10-K”) (each, a
“Subsidiary”). If the Company has no subsidiaries, any references to Subsidiaries in the Transaction Documents shall be disregarded. The Company owns, directly or indirectly, all of the capital stock of each Subsidiary free and
clear of Liens, and all the issued and outstanding shares of capital stock of each Subsidiary are validly issued and are fully paid, non-assessable and free of preemptive and similar rights. 
  
 (b) Organization and Qualification. Each of the
Company and the Subsidiaries is an entity duly incorporated or otherwise organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization (as applicable), with the requisite corporate power and
authority to own and use its properties and assets and to carry on its business as currently conducted. Neither the Company nor any Subsidiary is in violation of any of the provisions of its respective certificate or articles of incorporation,
bylaws or other organizational or charter documents. Each of the Company and the Subsidiaries is duly qualified to conduct business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature 

  

 5 








 
of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the
case may be, would not have or reasonably be expected to result in (i) a material adverse effect on the legality, validity or enforceability of any Transaction Document, (ii) a material adverse effect on the results of operations, assets, business
or financial condition of the Company and the Subsidiaries, taken as a whole, or (iii) a material adverse effect on the Company’s ability to perform in any material respect on a timely basis its obligations under any Transaction Document (any
of (i), (ii) or (iii), a “Material Adverse Effect”). 
  
 (c) Authorization; Enforcement. The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents and otherwise to
carry out its obligations thereunder. The execution and delivery of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated thereby have been duly authorized by all necessary action on the part of
the Company and no further action is required by the Company in connection therewith. Each Transaction Document has been (or upon delivery will have been) duly executed by the Company and, when delivered in accordance with the terms hereof, will
constitute the valid and binding obligation of the Company enforceable against the Company in accordance with its terms except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application
affecting enforcement of creditors’ rights generally and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies, and (iii) with respect to the indemnification provisions set
forth in the Registration Rights Agreement, as limited by public policy. 
  
 (d) No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated thereby do not and will not (i)
conflict with or violate any provision of the Company’s or any Subsidiary’s certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, or constitute a default (or an event that
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 (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or
other instrument (evidencing a Company or Subsidiary debt or otherwise) or other understanding to which the Company or any Subsidiary is a party or by which any property or asset of the Company or any Subsidiary is bound or affected, or (iii) result
in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or a Subsidiary is subject (including federal and state securities laws and
regulations), or by which any property or asset of the Company or a Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as would not have or reasonably be expected to result in a Material Adverse Effect.

  
 (e) Filings, Consents and Approvals.
The Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other Person in connection
with the execution, delivery and performance by the Company of the Transaction Documents, other than (a) the filing with the Commission of 

  

 6 








 
the Registration Statement, the application(s) to each Trading Market for the listing of the Shares and Warrant Shares for trading thereon in the time and
manner required thereby, and applicable Blue Sky filings and (b) such as have already been obtained or such exemptive filings as are required to be made under applicable securities laws. 
  
 (f) Issuance of the Securities. The Securities are duly authorized and, when issued and paid for in
accordance with the Transaction Documents, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens. The Company has reserved from its duly authorized capital stock the maximum number of shares of Common Stock
issuable pursuant to this Agreement and the Warrants.

the exercise of employee stock options under the Company’s stock option plans and pursuant to the conversion or exercise of Common Stock Equivalents outstanding on the date hereof. No Person has any right of first refusal, preemptive right,
right of participation, or any similar right to participate in the transactions contemplated by the Transaction Documents. Except as a result of the purchase and sale of the Securities and except for employee stock options under the Company’s
stock option plans or a plan approved by the Board of Directors of the Company, or as disclosed in SEC Reports, there are no outstanding options, warrants, script rights to subscribe to, calls or commitments of any character whatsoever relating to,

Subsidiary is or may become bound to issue additional shares of Common Stock or Common Stock Equivalents. The issue and sale of the Securities will not obligate the Company to issue shares of Common Stock or other securities to any Person (other
than the Purchasers) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under such securities.

under the Securities Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) of the Exchange Act, for the two years preceding the date hereof (or such shorter period as the Company was required by law to file such material) (the

the Securities Act and the Exchange Act and the rules and regulations of the Commission promulgated thereunder, as applicable, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material

material respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of 

  

 7

could have or reasonably be expected to result in, a Material Adverse Effect. Except as disclosed in the SEC Reports, neither the Company nor any Subsidiary, nor, to the knowledge of the Company, any director or officer thereof, is or has been the
subject of any Action involving a claim of violation of or liability under federal or state securities laws or a claim of breach of fiduciary duty. There has not been, and to the knowledge of the Company, there is not pending or contemplated, any

Company or any Subsidiary received notice of a claim that it is in default under or that it is in violation of, any indenture, loan or credit agreement or any other agreement or instrument to which it is a party or by which it or any of its

Company and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the SEC Reports,

and other similar rights that are material for use in connection with their respective businesses at present as described in the SEC Reports and which the failure to so have could have or reasonably be expected to result in a Material Adverse Effect
(collectively, the “Intellectual Property Rights”). Except as disclosed in the 2004 Form 10-K, neither the Company nor any Subsidiary has received a written notice that the Intellectual Property Rights used by the Company or any
Subsidiary violates or infringes the rights of any Person. To the knowledge of the Company, all such Intellectual Property Rights are enforceable.

Company and (c) for other employee benefits, including stock option agreements under any stock option plan of the Company.

sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in
conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing
assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15 and 15d-15) for the Company and designed such
disclosure controls and procedures to ensure that material information relating to the Company, including its Subsidiaries, is made known to the certifying officers by others within those entities, particularly during the period in which the
Company’s Form 10-K or 10-Q, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of December 31, 2003 (such date, the
“Evaluation Date”). The Company presented in such Form 10-K for the year ended December 31, 2003 the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations
as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes in the Company’s internal control over financial reporting (as such term is defined in Exchange Act Rule 13a-15 and 15d-15) that has materially
affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by this Agreement. 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 

  

 10 








 
type contemplated in this Section that may be due in connection with the transactions contemplated by this Agreement. 
  
 (t) Private Placement. Assuming the accuracy of the
Purchasers’ representations and warranties set forth in Section 3.2, no registration under the Securities Act is required for the offer and sale of the Securities by the Company to the Purchasers as contemplated hereby. The issuance and sale of
the Securities hereunder does not contravene the rules and regulations of the Trading Market. 
  
 (u) Investment Company. The Company is not, and is not an Affiliate of, an “investment company” within the meaning of the
Investment Company Act of 1940, as amended. 
  
 (v) Registration Rights. No Person has any right to cause the Company to effect the registration under the Securities Act of any securities of the Company. 
  
 (w) Form S-3 Eligibility. The Company is eligible to register the resale of its Common Stock by the

the effect that the Company is not in compliance with the listing or maintenance requirements of such Trading Market. The Company is, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance with all such
listing and maintenance requirements. 
  
 (y)
Application of Takeover Protections. The Company and its Board of Directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution
under a rights agreement) or other similar anti-takeover provision under the Company’s Certificate of Incorporation (or similar charter documents) or the laws of its state of incorporation that is or could become applicable to the Purchasers as
a result of the Purchasers and the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including without limitation the Company’s issuance of the Securities and the Purchasers’ ownership of the
Securities.

Company confirms that, neither the Company nor any other Person acting on its behalf has provided any of the Purchasers or their agents or counsel with any information that constitutes or might constitute material, non-public information. The
Company understands and confirms that the Purchasers will rely on the foregoing representations and covenants in effecting transactions in securities of the Company. All disclosure provided to the Purchasers regarding the Company, its business and
the transactions contemplated hereby, including the Disclosure Schedules to this Agreement, furnished by or on behalf of the Company are true and correct and do not contain any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. 
  

 11 








 (aa) No Integrated Offering. Neither the Company, nor any of its Affiliates, nor
any Person acting on its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with
prior offerings (other than the “PIPE” transaction closed on April 7, 2004 in which Rodman & Renshaw, Inc. acted as placement agent and disclosed in the Company’s most recent SEC Report (the “2004 Transaction”))
by the Company for purposes of the Securities Act or any applicable shareholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the

be conducted including its capital needs taking into account the particular capital requirements of the business conducted by the Company, and projected capital requirements and capital availability thereof, and including the anticipated proceeds of
the sale of the Securities; and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient
to pay all amounts on or in respect of its debt when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be
payable on or in respect of its debt). 
  
 3.2 Representations
and Warranties of the Purchasers. Each Purchaser hereby, for itself and for no other Purchaser, represents and warrants as of the date hereof and as of the Closing Date to the Company as follows: 
  
 (a) Organization; Authority. Such Purchaser is an
entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with full right, corporate or partnership power and authority to enter into and to consummate the transactions contemplated by the
Transaction Documents and otherwise to carry out its obligations thereunder. The execution, delivery and performance by such Purchaser of the transactions contemplated by this Agreement has been duly authorized by all necessary corporate or similar
action on the part of such Purchaser. Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding
obligation of such Purchaser, enforceable against it in accordance with its terms. 
  
 (b) General Solicitation. Such Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or
other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or general advertisement. 
  

 12 








 (c) No Public Sale or Distribution. Such Purchaser is (i) acquiring the Shares and
(ii) upon exercise of the Warrants will acquire the Warrant Shares, for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the
Securities Act; provided, however, that by making the representations herein, such Purchaser does not agree to hold any of the Securities for any minimum or other specific term and reserves the right to dispose of the Securities at any
time in accordance with or pursuant to a registration statement or an exemption under the Securities Act. Such Purchaser is acquiring the Securities hereunder in the ordinary course of its business. Such Purchaser does not have any agreement or
understanding, directly or indirectly, with any Person to distribute any of the Securities. 
  
 (d) Accredited Investor Status. Such Purchaser is an “accredited investor” as that term is defined in Rule 501(a) of
Regulation D under the Securities Act. Such Purchaser is not required to be registered as a broker-dealer under Section 15 of the Exchange Act. 
  
 (e) Reliance on Exemptions. Such Purchaser understands that the Shares and Warrants 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 such Purchaser’s compliance with, the representations,
warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire the Common Stock and Warrants. 
  
 (f) Information. Such Purchaser and its advisors, if
any, have been furnished with all publicly available materials relating to the business, finances and operations of the Company and such other publicly available materials relating to the offer and sale of the Shares and Warrants as have been
requested by such Purchaser. Such Purchaser and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other due diligence investigations conducted by such Purchaser or its advisors,
if any, or its representatives shall modify, amend or affect such Purchaser’s right to rely on the Company’s representations and warranties contained herein. Such Purchaser understands that its investment in the Shares and Warrants
involves a high degree of risk. Such Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Shares and Warrants. 
  
 (g) No Governmental Review. Such Purchaser
understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Shares and Warrants or the fairness or suitability of the investment in the
Shares and Warrants nor have such authorities passed upon or endorsed the merits of the offering of the Shares and Warrants. 
  
 (h) Experience of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge,
sophistication and experience in business and financial matters, including investing in biotechnology companies, so as to be 

  

 13 








 
capable of evaluating the merits and risks of the prospective investment in the Shares and Warrants, and has so evaluated the merits and risks of such
investment. Such Purchaser is able to bear the economic risk of an investment in the Shares and Warrants and, at the present time, is able to afford a complete loss of such investment. 
  
 The Company acknowledges and agrees that each Purchaser does not make or has not made any representations or warranties with
respect to the transactions contemplated hereby other than those specifically set forth in this Section 3.2. 
  
 ARTICLE IV. 
 OTHER AGREEMENTS OF THE PARTIES 
  
 4.1 Transfer Restrictions. 
  
 (a) The Securities may only be disposed of in compliance
with state and federal securities laws. In connection with any transfer of Securities other than pursuant to an effective registration statement, to the Company, to an Affiliate of a Purchaser, in connection with a pledge as contemplated in Section
4.1(b), or in connection with a sale pursuant to Rule 144, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably
satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of
this Agreement and shall have the rights of a Purchaser under this Agreement and the Registration Rights Agreement. 
  
 (b) The Purchasers agree to the imprinting, so long as is required by this Section 4.1(b), of a legend on any of the Securities in the
following form: 
  
 THESE SECURITIES HAVE NOT BEEN REGISTERED
WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED
OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN
ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT. 
  

 14 








 The Company acknowledges and agrees that a Purchaser may from time to time pledge
pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the Securities to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the
Securities Act and, if required under the terms of such arrangement, such Purchaser may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal
opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Purchaser’s expense, the Company will execute and deliver such
reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities, including the preparation and filing of any required prospectus supplement under Rule 424(b)(3)
under the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders thereunder. 
  
 (c) Certificates evidencing the Shares and Warrant Shares shall not contain any legend (including the legend set forth in Section 4.1(b)),
(i) while a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities Act, or (ii) following any sale of such Shares or Warrant Shares pursuant to Rule 144, or (iii) if such
Shares or Warrant Shares are eligible for sale under Rule 144(k), or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the Staff of the
Commission). The Company shall cause its counsel to issue a legal opinion to the Company’s transfer agent promptly after the Effective Date if required by the Company’s transfer agent to effect the removal of the legend hereunder. If all
or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, such Warrant Shares shall be issued free of all legends. The Company agrees that following the Effective
Date or at such time as such legend is no longer required under this Section 4.1(c), it will, no later than five (5) Trading Days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a certificate representing
Shares or Warrant Shares, as the case may be, issued with a restrictive legend, deliver or cause to be delivered to such Purchaser a certificate representing such Securities that is free from all restrictive and other legends. The Company may not
make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section. 
  

(d) In addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, as liquidated damages
and not as a penalty, for each $1,000 of Shares or Warrant Shares (based on the Closing Price of the Common Stock on the date such Securities are submitted to the Company’s transfer agent) subject to Section 4.1(c), $10 per Trading Day
(increasing to $20 per Trading Day five (5) Trading Days after such damages have begun to accrue) for each Trading Day after such fifth Trading Day until such certificate is delivered. Nothing herein shall limit such Purchaser’s right to pursue
actual damages for the Company’s failure to deliver certificates representing any Securities as required by the Transaction Documents, and such Purchaser shall have the right to pursue all remedies available to it at law or in equity including,
without limitation, a decree of specific performance and/or injunctive relief. 
  

 15 








 (e) Each Purchaser, severally and not jointly, agrees that the removal of the restrictive
legend from certificates representing Securities as set forth in this Section 4.1 is predicated upon the Company’s reliance that the Purchaser will sell any Securities pursuant to either the registration requirements of the Securities Act,
including any applicable prospectus delivery requirements, or an exemption therefrom. 
  
 4.2 Furnishing of Information. As long as any Purchaser owns 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. Upon the request of any such holder of Securities, the Company shall deliver to such holder a written certification of a duly authorized officer as to whether it
has complied with the preceding sentence. As long as any Purchaser owns 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, all to the extent
required from time to time to enable such Person to sell such Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144. 
  
 4.3 Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in
respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the
Purchasers or that would be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market. 
  
 4.4 Participation in Future Financing. From the date hereof until 12 months after the Effective Date, upon any financing by the Company of its
Common Stock or Common Stock Equivalents (a “Subsequent Financing”), each Purchaser shall have the right to participate in up to 33.33% of such Subsequent Financing (the “Participation Maximum”). At least five
Trading Days prior to the closing of the Subsequent Financing, the Company shall deliver to each Purchaser a written notice of its intention to effect a Subsequent Financing (“Pre-Notice”), which Pre-Notice shall ask such Purchaser if it
wants to review the details of such financing (such additional notice, a “Subsequent Financing Notice”). Upon the request of a Purchaser, and only upon a request by such Purchaser, for a Subsequent Financing Notice, the Company
shall promptly, but no later than one Trading Day after such request, deliver a Subsequent Financing Notice to such Purchaser. The Subsequent Financing Notice shall describe in reasonable detail the proposed terms of such Subsequent Financing, the
amount of proceeds intended to be raised thereunder, the Person with whom such Subsequent Financing is proposed to be effected, and attached to which shall be a term sheet or similar document relating thereto. If by 6:30 p.m. (New York City time) on
the second Trading Day after all of the Purchasers have received the Pre-Notice, notifications by the Purchasers of their willingness to participate in the Subsequent Financing (or to cause their designees to participate) is, in the aggregate, less
than the total amount of the Subsequent Financing, then the Company may effect the remaining portion of such Subsequent Financing on the terms and to the Persons set forth in the Subsequent Financing Notice. If the Company receives no notice from a
Purchaser as of such fifth Trading Day, such Purchaser shall be deemed to have notified the Company that it does not elect to participate. The 

  

 16 








 
Company must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again have the right of participation set forth above
in this Section 4.4, if the Subsequent Financing subject to the initial Subsequent Financing Notice is not consummated for any reason on the terms set forth in such Subsequent Financing Notice within 60 Trading Days after the date of the initial
Subsequent Financing Notice. In the event the Company receives responses to Subsequent Financing Notices from Purchasers seeking to purchase more than the aggregate amount of the Subsequent Financing, each such Purchaser shall have the right to
purchase their Pro Rata Portion (as defined below) of the Participation Maximum. “Pro Rata Portion” is the ratio of (x) the Subscription Amount of Securities purchased by a participating Purchaser and (y) the sum of the aggregate
Subscription Amount of all participating Purchasers. 
  
 4.5
Securities Laws Disclosure; Publicity. The Company shall, by 8:30 a.m. Eastern time on the Business Day following the Closing Date, file a Current Report on Form 8-K or issue a press release, disclosing the transactions contemplated hereby
and make such other filings and notices in the manner and time required by the Commission. The Company and each Purchaser shall consult with each other in issuing any press releases with respect to the transactions contemplated hereby, and neither
the Company nor any Purchaser shall issue any such press release or otherwise make any such public statement without the prior consent of the Company, with respect to any press release of any Purchaser, or without the prior consent of each
Purchaser, with respect to any press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with
prior notice of such public statement or communication. 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 registration statement contemplated by the Registration Rights Agreement 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 subclause (i) or (ii). 
  
 4.6 Shareholders Rights Plan. No claim will be made or enforced by the
Company or any other Person that any Purchaser is an “Acquiring Person” under any shareholders rights plan or similar plan or arrangement in effect or hereafter adopted by the Company, or that any Purchaser could be deemed to trigger the
provisions of any such plan or arrangement, by virtue of receiving Securities under the Transaction Documents or under any other agreement between the Company and the Purchasers. 
  
 4.7 Non-Public Information. 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 the Company believes 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. 
  
 4.8 Use of Proceeds. Except as set forth on Schedule 4.8 attached
hereto, the Company shall use the net proceeds from the sale of the Securities hereunder for working capital purposes and not for the satisfaction of any portion of the Company’s debt (other than payment of trade payables in the ordinary course
of the Company’s business and prior practices), to 

  

 17 








 
redeem any Company equity or equity-equivalent securities or to settle any outstanding litigation. 
  
 4.9 Reimbursement. If any Purchaser becomes involved in any capacity
in any Proceeding (as defined in the Registration Rights Agreement) by or against any Person who is a stockholder of the Company (except as a result of sales, pledges, margin sales and similar transactions by such Purchaser to or with any current
stockholder), solely as a result of such Purchaser’s acquisition of the Securities under this Agreement, the Company will reimburse such Purchaser for its reasonable legal and other expenses (including the cost of any investigation preparation
and travel in connection therewith) incurred in connection therewith, as such expenses are incurred. The reimbursement obligations of the Company under this paragraph shall be in addition to any liability which the Company may otherwise have, shall
extend upon the same terms and conditions to any Affiliates of the Purchasers who are actually named in such action, proceeding or investigation, and partners, directors, agents, employees and controlling persons (if any), as the case may be, of the
Purchasers and any such Affiliate, and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company, the Purchasers and any such Affiliate and any such Person. The Company also agrees
that neither the Purchasers nor any such Affiliates, partners, directors, agents, employees or controlling persons shall have any liability to the Company or any Person asserting claims on behalf of or in right of the Company solely as a result of
acquiring the Securities under this Agreement. 
  
 4.10
Indemnification of Purchasers. The Company will indemnify and hold the Purchasers and their directors, officers, shareholders, partners, employees and agents (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 misrepresentation, breach or inaccuracy, or any allegation by a third party that, if true, would constitute a breach or inaccuracy, of any of the representations, warranties, covenants or agreements made by the
Company in this Agreement or in the other Transaction Documents; or (b) any cause of action, suit or claim brought or made against such Purchaser Party and arising solely out of or solely resulting from the execution, delivery, performance or
enforcement of this Agreement or any of the other Transaction Documents and without causation by any other activity, obligation, condition or liability pertaining to such Purchaser or a related Purchaser Party. The Company will reimburse such
Purchaser for its reasonable legal and other expenses (including the cost of any investigation, preparation and travel in connection therewith) incurred in connection therewith, as such expenses are incurred. 
  
 4.11 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 the Warrants. 
  
 4.12 Listing of
Common Stock. The Company hereby agrees to use commercially reasonable efforts to maintain the listing of the Common Stock on its current Trading Market, and as soon as reasonably practicable following the Closing (but not later than the earlier
of the Effective Date and the first anniversary of the Closing Date) to list the applicable Shares and 

  

 18 








 
Warrant Shares on such Trading Market. The Company further agrees, if the Company applies to have the Common Stock traded on any other Trading Market, it
will include in such application the Shares and the Warrant Shares, and will take such other action as is necessary or desirable in the opinion of the Purchasers to cause the Shares and Warrant Shares to be listed on such other Trading Market as
promptly as possible. The Company will take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading Market and will comply in all respects with the Company’s reporting, filing and other obligations
under the bylaws or rules of the Trading Market. 
  
 4.13
Future Financings. From the date hereof until 10 Trading Days after the Effective Date, other than as contemplated by this Agreement, neither the Company nor any Subsidiary shall issue or sell any Common Stock or Common Stock Equivalents.
Notwithstanding anything herein to the contrary, the 10 Trading Day period set forth in this Section 4.13 shall be extended for the number of Trading Days during such period in which (y) trading in the Common Stock is suspended by any Trading
Market, or (z) following the Effective Date, the Registration Statement is not effective or the prospectus included in the Registration Statement may not be used by the Purchasers for the resale of the Shares and the Warrant Shares. Notwithstanding
anything to the contrary herein, this Section 4.13 shall not apply to the following (a) the granting of options to employees, officers and directors of the Company pursuant to any stock option plan duly adopted by a majority of the non-employee
members of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose, or (b) the exercise of any security issued by the Company in connection with the offer and sale of
the Company’s securities pursuant to this Agreement, or (c) the exercise of or conversion of any convertible securities, options or warrants issued and outstanding on the date hereof, provided such securities have not been amended since the
date hereof, or (d) acquisitions or strategic investments, the primary purpose of which is not to raise capital. 
  
 4.14 Equal Treatment of Purchasers. No consideration shall be offered or paid to any person to amend or consent to a waiver or modification of any
provision of any of the Transaction Documents unless the same consideration is also offered to all of the parties to the Transaction Documents. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the
Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers equally as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase,
disposition or voting of Securities or otherwise. 
  
 4.15
Compliance with the Securities Laws. Each Purchaser agrees to comply with the requirements of Regulation M, if applicable, with respect to the sale of the Shares and Warrant Shares by the Purchaser. Each Purchaser hereby confirms its
understanding that it may not cover short sales made prior to the Effective Date with Shares or Warrant Shares registered for resale on the Registration Statement. Each Purchaser acknowledges that it does not intend to cover short positions made by
it before the Effective Date with Shares or Warrant Shares held by it and registered on the Registration Statement.

party against whom enforcement of any such waiver 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.

 5.9 Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents 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. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether
brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereto hereby irrevocably
submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, New York for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein
(including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such
court, that such suit, action or proceeding is improper. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by delivering a copy thereof via overnight
delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein

applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. If either party shall commence an action or proceeding to enforce any provisions of a

warranties, agreements and covenants contained herein shall survive the Closing and delivery of the Shares. 
  
 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 when counterparts have been signed by all parties and delivered so that the Company has counterparts signed by all Purchasers and each Purchaser has a counterpart signed by the Company, it being understood that
parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission, 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 signature page were an original thereof. 
  

 21 








 5.12 Severability. If any provision of this Agreement is held to be invalid or unenforceable in
any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a
reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement. 
  
 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, 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 and customary and reasonable indemnity, if requested. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs 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 Documents. The parties agree that monetary
damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation the defense that a
remedy at law would be adequate. 
  
 5.15 Payment Set
Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement
or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any
other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be
satisfied shall, to the extent permissible under applicable law, be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred. 
  
 5.16 Independent Nature of Purchasers’ Obligations and Rights.
The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser
under any Transaction Document. Nothing contained herein or in any Transaction Document, 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 Document. 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 Documents, 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 Documents. For reasons of administrative convenience only, Purchasers and their respective
counsel have chosen to communicate with the Company through FW. FW does not represent any of the Purchasers in this transaction but only the placement agent, Rodman & Renshaw, Inc. The Company has elected to provide all Purchasers with the same
terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by the Purchasers.
