The funding of any portion of the Purchase Price by the Placement Agent pursuant to this Section 1(b)(iii) shall not relieve a defaulting Regulation D Purchaser of any liability that it may have to the Company or the Placement Agent pursuant to this Agreement or for the breach of its obligations under this Agreement.

As used in this paragraph, the terms “offer” and “sale” have the meanings specified in Section 2(a)(3) of the Securities Act.

(x) Disclosure. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company confirms that neither it nor any other person acting on its behalf has provided any of the Regulation D Purchasers or their agents or counsel with any information that it believes constitutes or might constitute material, non-public information as of the date hereof. The Company understands and confirms that the Regulation D Purchasers will rely on the foregoing representation in effecting transactions in securities of the Company. All disclosure furnished by or on behalf of the Company to the Regulation D Purchasers regarding the Company, its business and the transactions contemplated hereby, is, to the knowledge of the Company, true and correct in all material respects as of the date of such disclosure and does not contain, to the knowledge of the Company, 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. The press releases disseminated by the Company during the twelve (12) months preceding the date of this Agreement taken as a whole do not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made and when made, not misleading. The Company acknowledges and agrees that no Regulation D Purchaser makes or has made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 2 hereof.

The Company acknowledges that the Placement Agent and, for purposes of the opinion to be delivered pursuant to Section 6 hereof, counsel to the Company, will rely upon the accuracy and truthfulness of the foregoing representations and hereby consents to such reliance.

4. COVENANTS.

(a) Reasonable Best Efforts. Each party shall use its reasonable best efforts to timely satisfy each of the conditions to be satisfied by it as provided in Sections 5 and 6 of this Agreement.

(b) Form D. The Company agrees to file a Form D with respect to the Securities as required under Regulation D and to comply with any applicable state securities and “Blue Sky” laws in connection with the sale of the Securities.

(c) Use of Proceeds. The net proceeds from the sale of the Securities will be used by the Company in the manner described in the COM under the caption titled “Use of Proceeds.”

(d) Fees and Expenses. Except as otherwise set forth in the Regulation D Purchase Documents, each party to this Agreement shall bear its own expenses in connection with the sale of the Securities to the Regulation D Purchasers.

(e) Publicity. The Regulation D Purchasers agree that they will not issue any press release or otherwise make any public statement, filing or other communication regarding the offering or the business, operations or financial condition of the Company without the prior consent of the Company, except to the extent required by law or legal process, in which case such Regulation D Purchaser shall provide the Company with prior notice of such disclosure. The Company agrees that it will not publicly disclose the names of the Regulation D Purchasers or include the names of the Regulation D Purchasers, without the prior written consent of the Regulation D Purchasers, in any press release or other public statement, filing or other communication, except (a) in any registration statement in which such Regulation D Purchaser is identified as a selling securityholder, or (b) to the extent required by law or legal process (including but not limited to by the filing of one or more Form Ds with the Commission regarding the Regulation D Placement), or (c) by the filing of the Transaction Documents as exhibits to one or more of the Company’s Exchange Act filings.

The Company shall, at or before 9:00 a.m., New York time, on the first trading day following execution of this Agreement, issue a press release disclosing the transactions contemplated hereby. No later than the second business day after the Closing Date, the Company shall file a Current Report on Form 8-K with the Commission describing the terms of the transactions contemplated by the Transaction Documents and including as exhibits to such Current Report on Form 8-K the Transaction Documents not previously filed. Neither the Company nor any direct or indirect subsidiary shall, nor shall any of their respective officers, directors, employees and agents, provide any Regulation D Purchasers with any material nonpublic information regarding the Company or any direct or indirect subsidiary from and after the issuance of the above referenced press release without the express written consent of such Regulation D Purchasers.

(f) Withholding Taxes. The Regulation D Purchasers shall deliver to the Company a properly completed and duly executed applicable Internal Revenue Service Form W-8 or W-9 that establishes a complete exemption from United States withholding tax. The Regulation D Purchasers will provide replacement forms upon the obsolescence of such forms or inaccuracy of any information thereon.

(g) Pledge of Securities. The Company agrees that a Regulation D 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 who agrees to be bound by the provisions of this Agreement and the Registration Rights Agreement and, if required under the terms of such arrangement, such Regulation D 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 Regulation D 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, if the Securities are subject to registration pursuant to the Registration Rights Agreement, 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.

(h) Listing of Common Stock. The Company hereby agrees to use reasonable best efforts to maintain the listing of the Common Stock on the American Stock Exchange, and as soon as reasonably practicable following the Closing to list all of the shares of Common Stock issuable upon conversion of the Securities on the American Stock Exchange. 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 all of the shares of Common Stock issuable upon conversion of the Securities, and will take such other action as is necessary to cause all of the shares of Common Stock issuable upon conversion of the Securities 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 the American Stock Exchange and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the American Stock Exchange.

(i) Subsequent Equity Sales. The Company agrees that it will not, without the prior written consent of the Regulation D Purchasers, during the period ending 90 days after June 18, 2007, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock or (iii) file with the Commission a registration statement under the Securities Act relating to any additional shares of Common Stock or securities convertible into, or exchangeable for, any shares of Common Stock, or publicly disclose the intention to effect any transaction described in clause (i), (ii) or (iii), whether any

such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; provided, however, that the foregoing shall not apply to (A) the sale of the Securities under the Commitment Letter or this Agreement or the issuance of the Common Stock upon conversion of the Securities, (B) the issuance of additional Securities pursuant to the Investment Rollover Right, as defined in Section 18 of the Certificate of Designations, (C) the grant by the Company of employee or director stock options, restricted stock awards or restricted stock unit awards in the ordinary course of business, the issuance by the Company of any shares of Common Stock of the Company upon the exercise of an option or upon the sale by the Company of shares of Common Stock pursuant to the Company’s employee stock purchase plan, (D) any transfer of shares of Common Stock pursuant to the Company’s 401(k) plan, if any, (E) the filing by the Company of any registration statement with the Commission on Form S-8 relating to the offering of securities pursuant to the terms of the Company’s existing incentive plan or employee stock purchase plan, (F) the Company’s initial filing or filing of an amendment to any registration statement with the Commission on Form S-3 in accordance with the terms of any previously executed registration rights agreement or in response to any Commission comment letters, (G) the conversion or exercise of a security outstanding on the date hereof and (H) filing of any registration statement in respect of the Securities and the Common Stock.

5. CONDITIONS TO THE COMPANY’S OBLIGATION TO SELL.

The obligation of the Company hereunder to issue and sell the Securities to the Regulation D Purchasers at the Closing is subject to the satisfaction, at or before the Closing Date, of each of the following conditions, provided that these conditions are for the Company’s sole benefit and may be waived by the Company at any time in its sole discretion by providing the Regulation D Purchasers with prior written notice thereof.

(a) The representations and warranties of the Regulation D Purchasers shall be true and correct in all material respects as of the date when made and as of the Closing Date as though made at that time (except for representations and warranties that speak as of a specific date), and the Regulation D Purchasers shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by the Regulation D Purchasers at or prior to the Closing Date.

(b) No injunction, restraining order or order of any nature by a governmental authority shall have been issued as of the Closing Date that would prevent or materially interfere with the consummation of the Regulation D Placement or any of the transactions contemplated thereby; and no stop order suspending the qualification or exemption from qualification of any of the Securities in any jurisdiction shall have been issued and no proceeding for that purpose shall have been commenced or, to the knowledge of the Regulation D Purchasers after reasonable inquiry, be pending or contemplated as of the Closing Date.

(d) No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any federal, state or foreign governmental or

regulatory authority of competent jurisdiction that would, as of the Closing Date, render impossible the issuance or sale of the Securities; and no injunction or order of any federal, state or foreign court shall have been issued that would, as of the Closing Date, prevent the issuance or sale of the Securities.

6. CONDITIONS TO THE REGULATION D PURCHASERS’ OBLIGATION TO PURCHASE.

The several obligations of the Regulation D Purchasers hereunder to purchase the Securities at the Closing are subject to the satisfaction, at or before the Closing Date, of each of the following conditions, provided that these conditions are for the Regulation D Purchasers’ sole respective benefit and may be waived by the Regulation D Purchasers at any time in their sole discretion (each with respect to itself only) by providing the Company with prior written notice thereof.

(a) The Company shall have executed and delivered, or caused to be delivered, to the Regulation D Purchasers or the Placement Agent (i) each of the Transaction Documents to which it is a party and (ii) the Securities being purchased by the Regulation D Purchasers at the Closing pursuant to this Agreement, in each case in form and substance reasonably satisfactory to the Regulation D Purchasers or their agents.

(b) The Transactions shall have been consummated in accordance with their terms and in accordance with the applicable Transaction Documents and as described in the COM.

(d) [omitted]

(e) On the Closing Date, the Regulation D Purchasers or the Placement Agent (on behalf of the Regulation D Purchasers) shall have received the opinions of Akin Gump Xxxxxxx Xxxxx & Xxxx LLP, U.S. counsel for the Company, dated as of the Closing Date, substantially to the effect set forth on Annex B.

(f) The Company shall have delivered to the Regulation D Purchasers or the Placement Agent (on behalf of the Regulation D Purchasers) a certificate evidencing qualification by such entity as a foreign corporation and good standing issued by the Secretaries of State (or comparable office) of each of the jurisdictions in which the Company operates as of a date within 30 days prior to the Closing Date.

(g) The Company shall have delivered to the Regulation D Purchasers or the Placement Agent (on behalf of the Regulation D Purchasers) a certificate, executed by the Secretary of the Company, and dated as of the Closing Date, as to (i) the resolutions consistent with Sections 3(f) and 3(h) as adopted by Board of Directors of the Company in a form reasonably acceptable to the Regulation D Purchasers, and (ii) the certificate of incorporation and bylaws, or other organizational documents of the Company.

(h) The representations and warranties of the Company contained herein shall be true and correct as of the date when made and as of the Closing Date as though made at that time (except for representations and warranties that speak as of a specific date), and the Company shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by the Company at or prior to the Closing Date. The Regulation D Purchasers or the Placement Agent (on behalf of the Regulation D Purchasers) shall have received certificates, executed by an authorized officer of the Company, dated as of the Closing Date, to the foregoing effect. The statements of the Company and its respective officers made in any certificates delivered pursuant to this Agreement may be made only in their official, rather than individual capacity, and shall be true and correct on and as of the Closing Date.

(i) No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any federal, state or foreign governmental or regulatory authority of competent jurisdiction that would, as of the Closing Date, render impossible the issuance or sale of the Securities; and no injunction or order of any federal, state or foreign court shall have been issued that would, as of the Closing Date, prevent the issuance or sale of the Securities.

7. TERMINATION.

In the event that the Closing shall not have occurred due to the failure of the Company or the Regulation D Purchasers to satisfy the conditions set forth in Sections 5 and 6 above (and the nonbreaching party’s failure to waive such unsatisfied condition(s)), the nonbreaching party shall have the option to terminate this Agreement with respect to such breaching party at the close of business on the third business day following the date previously scheduled to be the Closing Date subject to Section 1(a)(ii).

8. INDEMNIFICATION.

(i) In consideration of the Regulation D Purchasers’ execution and delivery of this Agreement and the issuance of the Securities, and acquiring the Securities hereunder and in addition to all of the other obligations of the Company under this Agreement, the Company, shall defend, protect, indemnify and hold harmless the Regulation D Purchasers and the Regulation D Purchasers’ 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 (each, an “Indemnitee” and 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 (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to any misrepresentation or breach of any representation or warranty made by the Company in this Agreement or any other certificate, instrument or document contemplated hereby or thereby. 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.

(ii) Promptly after receipt by an Indemnitee under this Section 8 of notice of any claim or the commencement of any action or proceeding (including any governmental investigation), such Indemnitee will, if a claim for indemnification in respect thereof is to be made against the Company, notify the Company in writing of the commencement thereof; but the omission to so notify will not relieve it from any liability which the Company may have to any Indemnitee to the extent the Company is not materially prejudiced as a result thereof. In case any such action or proceeding is brought against any Indemnitee, and it notifies the Company of the commencement thereof, the Company will be entitled to participate therein, and to the extent that it may elect, by written notice delivered to such Indemnitee promptly after receiving the aforesaid notice from such Indemnitee, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnitee; provided, however, that if the defendants (including any impleaded parties) in any such action include both the Indemnitee and the Company (as applicable) and the Indemnitee shall have reasonably concluded that there may be legal defenses available to it and/or other Indemnitees which are different from or in addition to those available to the Company, the Indemnitee or Indemnitees shall have the right to select separate counsel to defend such action on behalf of such Indemnitee or Indemnitees. Upon receipt of notice from the Company to such Indemnitee of its election to so appoint counsel to defend such action and approval by the Indemnitee of such counsel, the Company will not be liable to such Indemnitee under this Section 8 for any legal or other expenses subsequently incurred by such Indemnitee in connection with the defense thereof unless: (A) the Indemnitee shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the Company shall not be liable for the expense of more than one separate counsel, approved by the Indemnitee representing the Indemnitees who are parties to such action); (B) the Company shall not have employed counsel reasonably satisfactory to the Indemnitee to represent the Indemnitee within a reasonable time after notice or commencement of the action; (C) the Company has authorized the employment of counsel for the Indemnitee at the expense of the Company; or (D) the use of counsel chosen by the Company to represent the Indemnitee would reasonably be expected to present such counsel with a conflict of interest.

(iii) The Company will not without the prior written consent of the Indemnitees, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the Indemnitees are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each Indemnitee from all liability arising out of such claim, action, suit or proceeding and does not include an admission of guilt of, or failure to act by, the Indemnitee, or include any injunctive relief against any Indemnitee. The Company shall not be liable for any settlement, compromise or the consent to the entry of judgment in connection with any such action effected without its written consent, but if settled with its written consent or if there be a final judgment for the plaintiff in any such action other than a judgment entered with the consent of such Indemnitee, then the Company shall indemnify and hold harmless any Indemnitee from and against any loss or liability by reason of such settlement or judgment.

(iv) Each Indemnitee shall furnish such information regarding itself or the claim in question as the Company may reasonably request in writing and as shall be reasonably required in connection with the defense of such claim and litigation arising therefrom.

(v) Notwithstanding anything to the contrary herein, the rights and remedies provided in this Section 8 are the sole rights with respect to the transactions contemplated by this Agreement and no party hereto shall make any other claim for costs, damages, expenses (including fees and expenses of attorneys, consultants, experts or other representatives) or any fine, penalty or any liability of any other nature or otherwise, under, arising out of or relating to this Agreement, or the transactions contemplated hereby, whether based on contract, tort, strict liability, other laws or otherwise.

(vi) Notwithstanding anything to the contrary herein, the provisions of this Section 8 are intended solely for the benefit of the Regulation D Purchasers and not for the benefit of, nor may any provision hereby be enforced by, any other Person.

(vii) No indemnification may be sought under this Section 8 by any Person who would have been entitled to indemnification under this Section 8 more than two years after the date of this Agreement.

9. MISCELLANEOUS.

(a) Notices. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or (iii) one business day after deposit with an overnight courier service, in each case properly addressed to the party to receive the same.

Each party 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 brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. 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 to such party at the address for such 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. Each party hereby irrevocably waives any right it may have, and agrees not to request, a jury trial for the adjudication of any dispute hereunder or in connection with or arising out of this Agreement or any transaction contemplated hereby.

(c) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns; provided that no party shall assign any of its rights or obligations hereunder without the prior written consent of the other party.

(d) Survival. Unless this Agreement is terminated under Section 7, the representations and warranties of the parties hereto contained in Sections 2 and 3, respectively, and the agreements and covenants set forth in Sections 4 and 8 shall survive the Closing.

(e) Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

(f) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant

or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

(g) Entire Agreement. The Transaction Documents and the Commitment Letter constitute the entire agreements of the parties to this Agreement and supersede all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof.

(h) Amendment. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The failure by any party to exercise any right or remedy under this Agreement or otherwise, or delay by a party in exercising such right or remedy, shall not operate as a waiver thereof. Any amendment to this Agreement made in conformity with the provisions of this Section 8(h) shall be binding on the Regulation D Purchasers and all holders of the Securities purchased under this Agreement, as applicable.

(i) Counterparts. This Agreement may be executed in two or more identical counterparts, all of which 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; provided, that a facsimile signature shall be considered due execution and shall be binding upon the signatory thereto with the same force and effect as if the signature were an original, not a facsimile signature.

(j) Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

(k) No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person; provided, however, that the Placement Agent may rely upon Sections 2, 3, and 4 hereof as if such representations, warranties, agreements and covenants, as applicable, were made directly to the Placement Agent. The parties further agree that the Placement Agent may rely on or, if the Placement Agent so requests, be specifically named as an addressee of, the legal opinions to be delivered pursuant to Section 6(e) of this Agreement.

(l) Independent Nature of Regulation D Purchasers’ Obligations and Rights. The obligations of each Regulation D Purchaser under any Transaction Document are several and not joint with the obligations of any other Regulation D Purchaser, and no Regulation D Purchaser shall be responsible in any way for the performance of the obligations of any other Regulation D Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Regulation D Purchaser pursuant hereto or thereto, shall be deemed to constitute the Regulation D Purchasers as, and the Company

acknowledges that the Regulation D Purchasers do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Regulation D Purchasers are in any way acting in concert or as a group, and the Company will not assert any such claim with respect to such obligations or the transactions contemplated by the Transaction Documents and the Company acknowledges that the Regulation D Purchasers are not acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. The Company acknowledges and each Regulation D Purchaser confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Regulation D Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction Documents, and it shall not be necessary for any other Regulation D Purchaser to be joined as an additional party in any proceeding for such purpose.

(m) Limitation on Duties of Placement Agent; Exculpation. Each party hereto agrees for the express benefit of each of the Placement Agent, its respective affiliates and its respective representatives that:

(i) Neither the Placement Agent, nor any of its respective affiliates or any of their representatives has any duties or obligations other than those specifically set forth herein.

(ii) Neither the Placement Agent nor any of its respective affiliates or respective representatives (1) shall be liable for any improper payment made in accordance with the information provided by the Company; (2) makes any representation or warranty, or has any responsibilities, as to the validity, accuracy, value or genuineness of any information, certificates or documentation delivered by or on behalf of the Company pursuant to this Agreement, the Placement Agency Agreement or the other Transaction Documents or in connection with any of the transactions contemplated hereby or thereby, including any information in the Preliminary COM or the COM or (3) shall be liable (x) for any action taken, suffered or omitted by any of them in good faith and reasonably believed to be authorized or within the discretion or rights or powers conferred upon it by this Agreement, the Placement Agency Agreement or any other Transaction Document or (y) for anything the Placement Agent may do or refrain from doing in connection with this Agreement, the Placement Agency Agreement or any other Transaction Document, except for such party’s own gross negligence, willful misconduct or bad faith.

(iii) The Placement Agent and its respective affiliates shall be entitled to (1) rely on, and shall be protected in acting upon, any certificate, instrument, opinion, notice, letter or any other document or security delivered to any of them by or on behalf of the Company, and (2) be indemnified by the Company for acting as Placement Agent pursuant to the indemnification provisions set forth in the Placement Agency Agreement, which hereby are incorporated by reference herein.
