REPRESENTATIONS AND WARRANTIES

3.1 Representations and Warranties of the Company. The Company represents and warrants to each Purchaser, except as disclosed or incorporated by reference in the Registration Statement:

(a) Subsidiaries. The Company has no direct or indirect Subsidiaries other than those listed in the SEC Reports. The Company owns, directly or indirectly, all of the capital stock or comparable equity interests of each Subsidiary free and clear of any and all Liens, other than restrictions on transfer under applicable securities laws and Liens imposed pursuant to that certain Credit Agreement dated October 4, 2005, as amended, to which Wells Fargo Foothill, Inc. is a party and which is an exhibit to the Company’s Current Report on Form 8-K filed with the Commission on October 6, 2005 (with amendments filed as an exhibit to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005, the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2006 and the Company’s Current Report on Form 8-K filed with the Commission on November 14, 2006, respectively), and all the issued and outstanding shares of capital stock or comparable equity interests of each Subsidiary are validly issued and are fully paid, non-assessable and free of preemptive and similar rights.

The Company and each Subsidiary 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 power and authority to own and use its properties and assets and to carry on its business as currently conducted, except where the failure to be validly existing or in good standing would not, individually or in the aggregate, have or reasonably be

6

expected to result in a Material Adverse Effect. 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, charter or equivalent documents. The Company and each Subsidiary 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 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, individually or in the aggregate, have or reasonably be expected to have 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 hereunder and thereunder. The execution and delivery of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated hereby and 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 herewith and therewith other than in connection with the Required Approvals. 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.

(d) No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company, the issuance and sale of the Shares and the consummation by the Company of the other transactions contemplated hereby and 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, result in the creation of any Lien upon any of the properties or assets of the Company or any Subsidiary, 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) subject to the Required Approvals, conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of the Nasdaq Global Market, any court or governmental authority to which the Company or a Subsidiary is subject (including federal, state and local laws applicable to its business and federal and state securities laws and regulations and the rules and regulations of any self regulatory organization to which the Company or its securities are subject) or by which any property or asset of the Company is bound or affected, or (iv) conflict with or violate the terms of any agreement by which the Company is bound or to which any property or asset of the Company is

7

bound or affected; except in the case of each of clauses (ii), (iii) and (iv), such as would not have or reasonably be expected to result in, individually or in the aggregate, a Material Adverse Effect.

(e) Filings, Consents and Approvals. The Company is not required to obtain any consent, approval (including, but not limited to, the approval of the stockholders of the Company), 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 (i) filings required pursuant to Sections 4.1 and 4.4, (ii) filings required in connection with the issuance and listing on the Nasdaq Global Market of the Shares and (iii) such filings as are required to be made under applicable state securities laws (collectively, the “Required Approvals”).

(f) Issuance of the Shares; Reservation of Common Stock. The Shares are duly authorized and, when issued and paid for in accordance with this Agreement, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens created by the Company or any of its Subsidiaries. The Company has reserved from its duly authorized capital stock the maximum number of shares of Common Stock issuable pursuant to this Agreement. The Shares have been registered under the Securities Act and all of the Shares will be freely transferable and tradable by the Purchasers without restriction created by the Company or any of its Subsidiaries. The Registration Statement is effective and available for the issuance of the Shares and the Company has not received any notice that the Commission has issued or intends to issue a stop-order with respect to the Registration Statement or that the Commission otherwise has suspended or withdrawn the effectiveness of the Registration Statement, either temporarily or permanently, or intends or has threatened in writing to do so. The “Plan of Distribution” section under the Registration Statement permits the issuance and sale of the Shares hereunder. Upon receipt of the Shares and making payment for them in accordance with the terms hereof, the Purchasers will have good and marketable title to such Shares and the Shares will be freely tradable on the Nasdaq Global Market. As of the date hereof, the Company has reserved a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue the Shares pursuant to this Agreement.

(g) Capitalization. As of March 31, 2007, the capitalization of the Company was as described in the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2007 as filed with the Commission. The Company has not issued any capital stock since such filing other than pursuant to the exercise of employee stock options under the Company’s stock option plans, the issuance of shares of Common Stock to employees pursuant to the Company’s employee stock purchase plan and pursuant to the conversion, exercise or exchange of outstanding Common Stock Equivalents and as disclosed in the SEC Reports. No Person has any right of first refusal, preemptive right, registration right, right of participation, or any similar right to participate in the transactions contemplated by the Transaction Documents. The issue and sale of the Shares will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than the Purchasers) and, except as disclosed in the Prospectus Supplement, will not result in a right of any holder of securities of the

8

Company to adjust the exercise, conversion, exchange or reset price under such securities. All of the outstanding shares of capital stock of the Company have been duly authorized and are validly issued, fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and none of such outstanding shares was issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities. No further approval or authorization of any stockholder, the Board of Directors of the Company or any other third party is required for the issuance and sale of the Shares. Except as disclosed in the SEC Reports, there are no stockholders’ agreements, voting agreements or other similar agreements with respect to the Company’s capital stock to which the Company is a party or, to the knowledge of the Company, between or among any of the Company’s stockholders. Since March 18, 2004, the Company’s date of inception, all options to purchase shares of the Company’s Common Stock granted by the Company to its directors, officers, employees or consultants, pursuant to the Company’s stock option plans, or otherwise, provided for an exercise price equal to no less than the fair market value of the underlying shares of the Company’s Common Stock on the date of grant, except where the failure of such options to be granted at an exercise price equal to less than the fair market value of the underlying shares of the Company’s Common Stock on the date of grant would not reasonably be expected to (i) cause the Company to restate any previously issued financial statements or (ii) result in a delay in the filing after the date hereof of a quarterly report on Form 10-Q or an annual report on Form 10-K by the Company, which delay in filing would cause the Company to lose its eligibility to file registration statements on Form S-3.

(h) SEC Reports; Financial Statements. Except for the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2004 and the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2005, both of which were filed with the Commission on August 1, 2005, the Company has filed all reports required to be filed by it pursuant to Section 13(a) of the Exchange Act since June 30, 2005 on a timely basis (or has received a valid extension of such time of filing and has filed any such SEC Reports prior to the expiration of any such extension). As of their respective dates, the SEC Reports complied in all material respects with the requirements of the Securities Act and the Exchange Act and the rules and regulations of the Commission promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a 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 Registration Statement and any prospectus included therein, including the prospectus supplement to be filed covering the transactions covered hereby, comply or will comply, as the case may be, in all material respects with the requirements of the Securities Act and the Exchange Act and the rules and regulations of the Commission promulgated thereunder, and none of the Registration Statement or any such prospectus contain or contained any untrue statement of a material fact or omits or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the case of any prospectus in the light of the circumstances under which they were made, not misleading.

9

of the Commission with respect thereto as in effect at the time of filing. Such financial statements have been prepared in accordance with GAAP, except as may be otherwise specified in such financial statements or the notes thereto or as may otherwise be permitted or required by Form 10-K or Form 10-Q under the Exchange Act and except that unaudited financial statements may not contain all footnotes required by GAAP, and fairly present in all material respects the financial position of the Company and its consolidated subsidiaries as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments.

There has not been, and to the knowledge of the Company and any Subsidiary, there is not pending or contemplated, any investigation by the Commission involving the Company or any current or former director or officer of the Company (in their capacities as directors or officers of the Company). The Commission has not issued any stop order or other order suspending the effectiveness of any registration statement filed by the Company under the Exchange Act or the Securities Act.

(o) Title to Assets. The Company and each Subsidiary has good and marketable title in fee simple to all real property owned by them that is material to their respective business and good and marketable title in all personal property owned by the Company and each Subsidiary that is material to their respective business, in each case free and clear of all Liens, except for Liens as do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company and each Subsidiary. Any real property and facilities or personal property held under lease by the Company and any Subsidiary is held by the Company and such Subsidiary, respectively, under valid, subsisting and enforceable leases of which the Company and such Subsidiary are in compliance, except as would not, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect.

The Company is in compliance with all such listing and maintenance requirements for continued listing of the Common Stock on the Trading Market. The issuance and sale of the Shares under the Transaction Documents does not contravene the rules and regulations of the Trading Market on which the Common Stock is currently listed or quoted (including Rule 4350 of the Nasdaq Stock Market if the Trading Market is the Nasdaq Global Market or Nasdaq Capital Market), and no approval of the stockholders of the Company thereunder is required for the Company to issue and deliver to the Purchasers the maximum number of Shares contemplated by Transaction Documents, including such as may be required pursuant to Nasdaq Rule 4350.

12

any offers or sales of any security or solicited any offers to buy any security, under circumstances that would, to the knowledge of the Company, cause the sale of the Shares to be integrated with prior offerings by the Company for purposes of any applicable stockholder 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 Company are listed or designated.

(t) Acknowledgment Regarding Purchasers’ Purchase of Shares. As between the Company and the Purchasers, the Company acknowledges and agrees that each of the Purchasers is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby. The Company further acknowledges that no Purchaser is acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to this Agreement and the transactions contemplated hereby and any advice given by any Purchaser or any of their respective representatives or agents in connection with this Agreement and the transactions contemplated hereby is merely incidental to the Purchasers’ purchase of the Shares.

(u) Acknowledgement Regarding Trading Activity. Anything in this Agreement or elsewhere herein to the contrary notwithstanding (except for Section 4.7 as to the Purchasers), it is understood and agreed by the Company (i) that, except as may be set forth in any “no trade” letter between RBC and a third party, none of the Purchasers or any Person to whom an offer of Shares have been made (each, an “Offeree”) have been asked to agree, nor has any Purchaser or Offeree agreed, to desist from purchasing or selling, long and/or short, securities of the Company, or “derivative” securities based on securities issued by the Company or to hold the Shares, securities of the Company, or “derivative” securities based on securities issued by the Company for any specified term; (ii) that past or future open market or other transactions by any Purchaser or Offeree, including without limitation, Short Sales or “derivative” transactions, before or after the closing of this or future private placement transactions, may negatively impact the market price of the Company’s publicly-traded securities; (iii) that any Purchaser or Offeree, and counter parties in “derivative” transactions to which any such Purchaser or Offeree is a party, directly or indirectly, presently may have a “short” position in the Common Stock, and (iv) that no Purchaser or Offeree shall be deemed to have any affiliation with or control over any arm’s length counter-party in any “derivative” transaction.

(v) Transactions With Affiliates and Employees. None of the officers or directors of the Company and, to the knowledge of the Company, none of the employees of the Company is or was a party to any transaction with the Company or any Subsidiary (other than for services as employees, officers and directors) that would be required to be disclosed as of the date hereof in an SEC Report pursuant to the requirements of Item 404 of Regulation S-K promulgated under the Securities Act.

(w) Internal Accounting Controls. The Company and the Subsidiaries maintain a system of internal accounting controls 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)

13

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 to allow timely decisions regarding required disclosures. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of a date within 90 days prior to the filing date of the Form 10-K for the Company’s most recently ended fiscal year and the Form 10-Q for the Company’s most recently ended fiscal quarter (each such applicable date, the “Evaluation Date”). The Company presented in its most recently filed Form 10-K or Form 10-Q 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 and except as disclosed in the SEC Reports, there have been no changes in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

(x) Investment Company. The Company is not, and will not after the consummation of the offering of Shares contemplated by this Agreement be, an “investment company” or an Affiliate of an “investment company,” within the meaning of the Investment Company Act of 1940, as amended.

(y) Certain Fees. Except with respect to RBC, no brokerage or finder’s fees or commissions are or will be payable by the Company to any broker, financial 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 (other than such fees or commissions owed by an Purchaser pursuant to written agreements executed by such Purchaser which fees or commissions shall be the sole responsibility of such Purchaser ) made by or on behalf of other Persons for fees of a type contemplated in this Section 3.1(y) that may be due in connection with the transactions contemplated by this Agreement.

(z) Auditors. Effective following KPMG LLP’s (“KPMG”) review of the Company’s financial statements as of and for the three and nine months ended September 30, 2005, the Company changed auditors from KPMG to BDO. During the period from the date of KPMG’s original engagement by the Company through the date of their resignation, the Company had no disagreements with KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the former auditors’ satisfaction, would have caused them to make reference to the subject matter of the disagreement in connection with their report on the Company’s financial statements.

5.8 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 hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan 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 or inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or 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 shall be deemed to limit in any way any right to serve process in any manner permitted by law. The parties hereby waive all rights to a trial by jury. If any party shall commence an action or proceeding to enforce any provisions of the Transaction Documents, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable and documented attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

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 each party and delivered to the other party, it being understood that the 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.

5.11 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.

20

5.12 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

5.13 Replacement of Shares. If any certificate or instrument evidencing any Shares 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 Shares.

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 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. 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.

5.16 Acknowledgment Regarding RBC. Each Purchaser acknowledges that RBC is acting as a placement agent for the Shares being offered hereby and will be compensated by the Company for acting in such capacity. Each Purchaser further acknowledges that RBC has acted solely as agent of the Company in connection with the offering of the Shares by the Company. Each Purchaser further acknowledges that the provisions of Sections 2.2(a)(iii) and 2.3(b)(vi) and this Section 5.16 are for the benefit of and may be enforced by RBC.
