Each of the Company and its Subsidiaries is duly qualified as a foreign entity to do business and is in good standing in every jurisdiction in which its ownership of property or the nature of the business conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not reasonably be expected to have a Material Adverse Effect. As used in this Agreement, “Material Adverse Effect” means any material adverse effect on the business, properties, assets, operations, results of operations, condition (financial or otherwise) or prospects of the Company, its Subsidiaries, individually or taken as a whole, or on the transactions contemplated hereby or in the other Transaction Documents or by the agreements and instruments to be entered into in connection herewith or therewith, or on the authority or ability of the Company to perform its obligations under the Transaction Documents (as defined below). The Company has no Subsidiaries except as set forth on

For purposes of this Agreement: (x) “Indebtedness” of any Person means, without duplication (A) all indebtedness for borrowed money, (B) all obligations issued, undertaken or assumed as the deferred purchase price of property or services (including, without limitation, “capital leases” in accordance with generally accepted accounting principles) (other than trade payables entered into in the ordinary course of business), (C) all reimbursement or payment obligations with respect to letters of credit, surety bonds and other similar instruments, (D) all obligations evidenced by notes, bonds, debentures or similar instruments, including obligations so evidenced incurred in connection with the acquisition of property, assets or businesses, (E) all indebtedness created or arising under any conditional sale or other title retention agreement, or incurred as financing, in either case with respect to any property or assets acquired with the proceeds of such indebtedness (even though the rights and remedies of the seller or bank under such agreement in the event of default are limited to repossession or sale of such property), (F) all monetary obligations under any leasing or similar arrangement which, in connection with generally accepted accounting principles, consistently applied for the periods covered thereby, is classified as a capital lease, (G) all indebtedness referred to in clauses (A) through (F) above secured by (or for which the holder of such Indebtedness has an existing right, contingent or otherwise, to be secured by) any mortgage, lien, pledge, charge, security interest or other encumbrance upon or in any property or assets (including accounts and contract rights) owned by any Person, even though the Person which owns such assets or property has not assumed or become liable for the payment of such indebtedness, and (H) all Contingent Obligations in respect of indebtedness or obligations of others of the kinds referred to in clauses (A) through (G) above; (y) “Contingent Obligation” means, as to any Person, any direct or indirect liability, contingent or otherwise, of that Person with respect to any indebtedness, lease, dividend or other obligation of another Person if the primary purpose or intent of the Person incurring such liability, or the primary effect thereof, is to provide assurance to the obligee of such liability that such liability will be paid or discharged, or that any agreements relating thereto will be complied with, or that the holders of such liability will be protected (in whole or in part) against loss with respect thereto; and (z) “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization and a government or any department or agency thereof.

(t) Absence of Litigation. Except as set forth in Schedule 3(t), there is no action, suit, proceeding, inquiry or investigation before or by the Principal Market, any court, public board, government agency, self-regulatory organization or body pending or, to the knowledge of the Company, threatened against or affecting the Company or any of its Subsidiaries, the Common Stock or any of the Company’s Subsidiaries or any of the Company’s or its Subsidiaries’ officers or directors, whether of a civil or criminal nature or otherwise.

(u) Insurance. The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company and its Subsidiaries are engaged. Neither the Company nor any such Subsidiary has been refused any insurance coverage sought or applied for and neither the Company nor any such Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect.

(v) Employee Relations. (i) Neither the Company nor any of its Subsidiaries is a party to any collective bargaining agreement or employs any member of a union.

No executive officer of the Company or any of its Subsidiaries is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer does not subject the Company or any of its Subsidiaries to any liability with respect to any of the foregoing matters.

(ii) The Company and its Subsidiaries are in compliance with all federal, state, local and foreign laws and regulations respecting labor, employment and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

Any real property and facilities held under lease by the Company or any of its Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and its Subsidiaries.

intellectual property rights and all applications related thereto (“Intellectual Property Rights”) necessary to conduct their respective businesses as now conducted except where the failure to so own or possess would not reasonably be expected to result in a Material Adverse Effect. None of the Company’s or its Subsidiaries’ Intellectual Property Rights have expired, terminated or been abandoned, or are expected to expire, terminate or be abandoned, within three years from the date of this Agreement. The Company does not have any knowledge of any infringement by the Company or any of its Subsidiaries of Intellectual Property Rights of others. There is no claim, action or proceeding being made or brought, or to the knowledge of the Company, being threatened, against the Company or any of its Subsidiaries regarding its Intellectual Property Rights. The Company is unaware of any facts or circumstances which might give rise to any of the foregoing infringements or claims, actions or proceedings.

The term “Environmental Laws” means all federal, state, local or foreign laws relating to pollution or protection of human health or the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes (collectively, “Hazardous Materials”) into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials, as well as all authorizations, codes, decrees, demands or demand letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations issued, entered, promulgated or approved thereunder.

There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company know of no basis for any such claim.

(bb) Internal Accounting and Disclosure Controls. The Company and each of its 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 generally accepted accounting principles and to maintain asset and liability accountability, (iii) access to assets or incurrence of liabilities is permitted only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals and appropriate action is taken with respect to any difference. The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-14 under the 1934 Act) that are effective in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported, within the time periods specified in the rules and forms of the SEC, including, without limitation, controls and procedures designed in to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is accumulated and communicated to the Company’s management, including its principal executive officer or officers and its principal financial officer or officers, as appropriate, to allow timely decisions regarding required disclosure. Except as set forth in Schedule 3(bb), during the twelve months prior to the date hereof neither the Company nor any of its Subsidiaries have received any notice or correspondence from any accountant relating to any potential material weakness in any part of the system of internal accounting controls of the Company or any of its Subsidiaries.

(ee) Transfer Taxes. On the Closing Date, all stock transfer or other taxes (other than income or similar taxes) which are required to be paid in connection with the sale and transfer of the Securities to be sold to each Buyer hereunder will be, or will have been, fully paid or provided for by the Company, and all laws imposing such taxes will be or will have been complied with.

(ff) Acknowledgement Regarding Buyers’ Trading Activity. Except as set forth in Section 2(m) and Section 4(r), it is understood and acknowledged by the Company (i) that none of the Buyers have been asked by the Company or its Subsidiaries to agree, nor has any Buyer agreed with the Company or its Subsidiaries, 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 Securities for any specified term; (ii) that any Buyer, and counterparties in “derivative” transactions to which any such Buyer is a party, directly or

All disclosure provided to the Buyers regarding the Company and its Subsidiaries, their business and the transactions contemplated hereby, including the Schedules to this Agreement, furnished by or on behalf of the Company is true and correct and does 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 the light of the circumstances under which they were made, not misleading.

If the Basic Amounts subscribed for by all Buyers are less than the total of all of the Basic Amounts, then each Buyer who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, that if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and the Basic Amounts subscribed for (the "Available Undersubscription Amount"), each Buyer who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Basic Amount of such Buyer bears to the total Basic Amounts of all Buyers that have subscribed for Undersubscription Amounts, subject to rounding by the Company to the extent its deems reasonably necessary. Notwithstanding the foregoing, if the Company desires to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company may deliver to the Buyers a new Offer Notice and the Offer Period shall expire on the third (3rd) Business Day after such Buyer's receipt of such new Offer Notice.

(3) The Company shall have fifteen (15) Business Days from the expiration of the Offer Period above (i) to offer, issue, sell or exchange all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by the Buyers (the "Refused Securities") pursuant to a definitive agreement(s) (the "Subsequent Placement Agreement"), but only to the offerees described in the Offer Notice (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring person or persons or less favorable to the Company than those set forth in the Offer Notice and (ii) to publicly announce (a) the execution of such Subsequent Placement Agreement, and (b) either (x) the consummation of the transactions contemplated by such Subsequent Placement Agreement or (y) the termination of such Subsequent Placement Agreement, which shall be filed with the SEC on a Current Report on Form 8-K with such Subsequent Placement Agreement and any documents contemplated therein filed as exhibits thereto.

(4) In the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the terms specified in Section 4(n)(iii)(3) above), then each Buyer may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that such Buyer elected to purchase pursuant to Section 4(n)(iii)(2) above multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Buyers pursuant to Section 4(n)(iii)(3) above prior to such reduction) and (ii) the denominator of which shall be the

original amount of the Offered Securities. In the event that any Buyer so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Buyers in accordance with Section 4(n)(iii)(1) above.

(5) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, the Buyers shall acquire from the Company, and the Company shall issue to the Buyers, the number or amount of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to Section 4(n)(iii)(3) above if the Buyers have so elected, upon the terms and conditions specified in the Offer. The purchase by the Buyers of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Buyers of a purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to the Buyers and their respective counsel.

(6) Any Offered Securities not acquired by the Buyers or other persons in accordance with Section 4(n)(iii)(3) above may not be issued, sold or exchanged until they are again offered to the Buyers under the procedures specified in this Agreement.

(7) The Company and the Buyers agree that if any Buyer elects to participate in the Offer, (x) neither the Subsequent Placement Agreement with respect to such Offer nor any other transaction documents related thereto (collectively, the "Subsequent Placement Documents") shall include any term or provisions whereby any Buyer shall be required to agree to any restrictions in trading as to any securities of the Company owned by such Buyer prior to such Subsequent Placement, and (y) any registration rights set forth in such Subsequent Placement Documents shall be similar in all material respects to the registration rights contained in the Registration Rights Agreement.

(8) Notwithstanding anything to the contrary in this Section 4(n) and unless otherwise agreed to by the Buyers, the Company shall either confirm in writing to the Buyers that the transaction with respect to the Subsequent Placement has been abandoned or shall publicly disclose its intention to issue the Offered Securities, in either case in such a manner such that the Buyers will not be in possession of material non-public information, by the fifteen (15th) Business Day following expiration of the Offer Period. If by the fifteen (15th) Business Day following expiration of the Offer Period no public disclosure regarding a transaction with respect to the Offered Securities has been made, and no notice regarding the abandonment of such transaction has been received by the Buyers, such transaction shall be deemed to have been abandoned and the Buyers shall not be deemed to be in possession of any material, non-public information with respect to the Company. Should the Company decide to pursue such transaction with respect to the Offered Securities, the Company shall provide each Buyer with another Offer Notice and each Buyer will again have the right of participation set forth in this Section 4(n)(iii). The Company shall not be permitted to deliver more than one such Offer Notice to the Buyers in any 60 day period.

(9) The restrictions contained in subsections (ii) and (iii) of this Section 4(n) shall not apply in connection with the issuance of any Excluded Securities (as defined in the Certificate of Designations).

(10) In the event the Company has made a good faith determination that any matters relating to an Offer Notice required to be provided to any Buyer pursuant to this Section 4(n) constitute material non-public information, prior to providing such Offer Notice, the Company shall promptly inquire (either orally or in writing) to each Buyer whether such Buyer wants to receive any material nonpublic information (the "Material Event Notice"). Notwithstanding anything contained in this Section 4(n) to the contrary, the Company shall not deliver an Offer Notice that contains material nonpublic information to any Buyer that has not affirmatively indicated (either orally or in writing) that it wishes to receive material nonpublic information. Until the earlier to occur of (x) the date on which a Buyer gives notice (either orally or in writing) to the Company authorizing the delivery of material nonpublic information to the Buyer (the "Material Event Notice Acceptance") or (y) the date on which the material non-public information which was to be set forth in the Offer Notice is publicly disclosed in a filing with the SEC, the Company shall be relieved of any obligation imposed by this Section 4(n) to deliver an Offer Notice to the Buyer containing material nonpublic information and such Buyer shall be deemed to have waived the Buyer’s rights hereunder to receive such Offer Notice until such time as the Buyer delivers such Material Event Notice Acceptance to the Company. Notwithstanding anything in any Transaction Document to the contrary, the Company covenants and agrees that it shall not provide the Offer Notice to any Buyer which contains material non-public information until the earlier to occur of (x) such time as the Material Event Notice Acceptance is received by the Company or (y) the material non-public information which was to be set forth in the Offer Notice has been disclosed in a filing with the SEC.

(o) Stockholder Approval. The Company shall provide each stockholder entitled to vote at a special or annual meeting of shareholders of the Company (the "Stockholder Meeting"), which initially shall be promptly called and held not later than December 31, 2006 (the "Stockholder Meeting Deadline"), a proxy statement, substantially in the form which has been previously reviewed by the Buyers and Schulte Roth & Zabel LLP at the expense of the Company, soliciting each such stockholder's affirmative vote at the Stockholder Meeting for approval of resolutions (the "Resolutions") providing for the Company's issuance of all of the Securities as described in the Transaction Documents in accordance with applicable law and the rules and regulations of the Principal Market (such affirmative approval being referred to herein as the "Stockholder Approval" and the date such approval is obtained, the "Stockholder Approval Date"), and the Company shall use its reasonable best efforts to solicit its stockholders' approval of the Resolutions and to cause the Board to recommend to the stockholders that they approve the Resolutions. The Company shall be obligated to seek to obtain the Stockholder Approval by the Stockholder Meeting Deadline. If, despite the Company's reasonable best efforts, the Stockholder Approval is not obtained on or prior to the Stockholder Meeting Deadline, the Company shall solicit Stockholder Approval at the annual stockholders meeting each year and use its reasonable best efforts to obtain such Stockholder Approval until Stockholder Approval is obtained.

(p) Withholding Taxes. On each Dividend Date (as defined in the Certificate of Designations), if the Company does not have current or accumulated "earnings and profits" within the meaning of Sections 301 and 312 of the Internal Revenue Code of 1986, as amended, through such Dividend Date, the Company shall not withhold any amount of the applicable Dividend (as defined in the Certificate of Designations) in respect of U.S. federal income tax.

On or prior to any such Dividend Date, the Company shall deliver a transmittal letter to the Buyer or the Buyer's prime broker indicating whether the Company believes it must withhold any amount of such Dividend, whether the Company has any "earnings or profits" and the calculations, in reasonable detail, supporting such calculations.

(q) Lock-Up Agreements. The Company shall not amend, waive or modify any of the Lock-Up Agreements or the Existing Lock-Up Agreements (each as defined below) without the written consent of the Required Holders (as defined in the Certificate of Designations).

(r) Trading in Common Stock. For so long as such Buyer owns any Securities, such Buyer shall not maintain a Net Short Position. For purposes of this Section, a "Net Short Position" by a person means a position whereby such person has executed one or more sales of Common Stock that is marked as a short sale and that is executed at a time when such Buyer has no equivalent offsetting long position in the Common Stock or contract for the foregoing. For purposes of determining whether a Buyer has an equivalent offsetting long position in the Common Stock, all Common Stock (i) that is owned by such Buyer, (ii) that may be issued pursuant to the terms of the Certificate of Designations and/or the Warrants to the Buyer or (iii) that would be issuable upon conversion or exercise in full of all securities of the Buyer (including the Securities) then held by such Buyer (assuming that such securities were then fully convertible or exercisable, notwithstanding any provisions to the contrary, and giving effect to any conversion or exercise price adjustments that would take effect given only the passage of time) shall be deemed to be held long by such Buyer. Without limiting the foregoing, the Buyers may engage in hedging activities at various times during the period following the public announcement of the execution of this Agreement as provided in Section 4(i), and during the period that any Securities are outstanding.

(s) Approval of Principal Market. The Company shall use its best efforts, acting diligently and in good faith, to obtain the approval of the Principal Market with respect to the transactions contemplated by the Transaction Documents as soon as practicable.

(t) Consent of Union Bank of California. The Company shall use its best efforts, acting diligently and in good faith, to obtain the consent of Union Bank of California with respect to the transactions contemplated by the Transaction Documents as soon as practicable.

5. REGISTER; TRANSFER AGENT INSTRUCTIONS.

(a) Register. The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate by notice to each holder of Securities), a register for the Preferred Shares, the Common Shares and the Warrants in which the Company shall record the name and address of the Person in whose name the Preferred Shares, the Common Shares and the Warrants have been issued (including the name and address of each transferee), the number of Preferred Shares held by such Person and the number of Conversion Shares issuable upon conversion of the Preferred Shares and Warrant Shares issuable upon exercise of the Warrants held by such Person. The Company shall keep the register open

and available at all times during business hours for inspection of any Buyer or its legal representatives.

(b) Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent, and any subsequent transfer agent, to issue certificates or credit shares to the applicable balance accounts at The Depository Trust Company ("DTC"), registered in the name of each Buyer or its respective nominee(s), for the Common Shares issued at the Closing and for the Conversion Shares and the Warrant Shares in such amounts as specified from time to time by each Buyer to the Company upon conversion of the Preferred Shares or exercise of the Warrants in the form of Exhibit D attached hereto (the "Irrevocable Transfer Agent Instructions"). The Company warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 5(b), and stop transfer instructions to give effect to Section 2(h) hereof, will be given by the Company to its transfer agent with respect to the Securities, and that the Securities shall otherwise be freely transferable on the books and records of the Company, as applicable, and to the extent provided in this Agreement and the other Transaction Documents. If a Buyer effects a sale, assignment or transfer of the Securities in accordance with Section 2(g), the Company shall permit the transfer and shall promptly instruct its transfer agent to issue one or more certificates or credit shares to the applicable balance accounts at DTC in such name and in such denominations as specified by such Buyer to effect such sale, transfer or assignment. In the event that such sale, assignment or transfer involves Conversion Shares, Common Shares and/or Warrant Shares sold, assigned or transferred pursuant to an effective registration statement with prospectus delivery (unless an exemption from the prospectus delivery requirements is available), or pursuant to Rule 144, the transfer agent shall issue such Securities to the Buyer, assignee or transferee, as the case may be, without any restrictive legend.

(c) Breach. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to a Buyer and that the remedy at law for a breach of its obligations under this Section 5 will be inadequate. In addition, the Company agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 5, that a Buyer shall be entitled, in addition to all other available remedies, to seek an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

(d) Additional Relief. If the Company shall fail for any reason or for no reason to issue to such holder unlegended certificates within three (3) Business Days of receipt of documents necessary for the removal of legend set forth above (the "Deadline Date"), then, in addition to all other remedies available to the holder, if on or after the Trading Day (as defined in the Certificate of Designations) immediately following such three Business Day period, the holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the holder of shares of Common Stock that the holder anticipated receiving from the Company (a "Buy-In"), then the Company shall, within three Business Days after the holder's request and in the holder's discretion, either (i) pay cash to the holder in an amount equal to the holder's total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the "Buy-In Price"), at which point the Company's obligation to deliver such certificate (and to issue such shares of Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the holder a certificate or

certificates representing such shares of Common Stock and pay cash to the holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Bid Price on the Deadline Date. "Closing Bid Price" means, for any security as of any date, the last closing price for such security on the Principal Market, as reported by Bloomberg (as defined in the Certificate of Designations), or, if the Principal Market begins to operate on an extended hours basis and does not designate the closing bid price then the last bid price of such security prior to 4:00:00 p.m., New York Time, as reported by Bloomberg, or, if the Principal Market is not the principal securities exchange or trading market for such security, the last closing price of such security on the principal securities exchange or trading market where such security is listed or traded as reported by Bloomberg, or if the foregoing do not apply, the last closing price of such security in the over-the-counter market on the electronic bulletin board for such security as reported by Bloomberg, or, if no closing bid price is reported for such security by Bloomberg, the average of the bid prices of any market makers for such security as reported in the "pink sheets" by Pink Sheets LLC (formerly the National Quotation Bureau, Inc.). If the Closing Bid Price cannot be calculated for a security on a particular date on any of the foregoing bases, the Closing Bid Price of such security on such date shall be the fair market value as mutually determined by the Company and the holder. If the Company and the holder are unable to agree upon the fair market value of such security, then such dispute shall be resolved pursuant to Section 2(d)(iii) of the Certificate of Designations. All such determinations to be appropriately adjusted for any stock dividend, stock split, stock combination or other similar transaction during the applicable calculation period.

In consideration of each Buyer's execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in addition to all of the Company's other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless each Buyer and each other holder of the Securities (other than holders of Securities purchased on any Eligible Market (as defined in the Certificate of Designations) or the Principal Market with respect to those Securities), and all of such Buyer's stockholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons' agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the "Indemnitees"), as incurred, from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys' fees and disbursements, but excluding any consequential, indirect or incidental damages (the "Indemnified Liabilities"), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the

Company in the Transaction Documents, (b) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or (c) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Company) and arising out of or resulting from (i) the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (ii) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities, (iii) any disclosure made by such Buyer pursuant to Section 4(i), or (iv) the status of such Buyer or holder of the Securities (other than holders of Securities purchased on any Eligible Market or the Principal Market with respect to those Securities), as an investor in the Company pursuant to the transactions contemplated by the Transaction Documents. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. Except as otherwise set forth herein, the mechanics and procedures with respect to the rights and obligations under this Section 9(k) shall be the same as those set forth in Section 6 of the Registration Rights Agreement.

(l) No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

(m) Remedies. Each Buyer and each holder of the Securities shall have all rights and remedies set forth in the Transaction Documents and all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights which such holders have under any law. Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. Furthermore, the Company recognizes that in the event that it fails to perform, observe, or discharge any or all of its obligations under the Transaction Documents, any remedy at law may prove to be inadequate relief to the Buyers. The Company therefore agrees that the Buyers shall be entitled to seek temporary and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or other security. Notwithstanding anything to the contrary contained herein, no Buyer or holder of Securities shall be entitled to consequential, indirect or incidental damages hereunder. However, the foregoing shall not in any way limit a Buyer or holder of Securities from being reimbursed for its costs, fees or expenses, including, without limitation, reasonable attorneys' fees and disbursements in connection with any of its rights and remedies hereunder.

(n) Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Buyer 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 Buyer may rescind or withdraw, in its sole discretion from time to time prior to the Company's performance upon written notice to the Company, any
