     Section 7. Indemnification and Contribution.

          (a) The Company agrees to indemnify and hold harmless the Initial Purchaser against any losses, claims, damages or liabilities to which the Initial Purchaser may become subject, under the Securities Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum, the Time of Sale Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Offering Memorandum), any Pricing Term Sheet or Supplemental Offering Materials or in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities (“Marketing Materials”), including any roadshow or investor

presentations made to investors by the Company (whether in person or electronically) or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Initial Purchaser for any legal or other expenses reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability or action as such expenses are incurred; or (ii) in whole or in part upon any inaccuracy in the representations and warranties of the Company contained herein; or (iii) in whole or in part upon any failure of the Company to perform its obligations hereunder or under law; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Memorandum, the Time of Sale Disclosure Package, the Offering Memorandum, or any such amendment or supplement, any Pricing Term Sheet or Supplemental Offering Materials or in any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company by you specifically for use in the preparation thereof; it being understood and agreed that the only such information furnished by you consists of the information described as such in Section 7(f) hereof.

          (b) The Initial Purchaser will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Initial Purchaser, such consent not to be unreasonably withheld), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum, the Time of Sale Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto or any Pricing Term Sheet, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Offering Memorandum, the Time of Sale Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto, or any Pricing Term Sheet in reliance upon and in conformity with written information furnished to the Company by you, specifically for use in the preparation thereof (it being understood and agreed that the only such information furnished by you consists of the information described as such in Section 7(f) hereof), and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending against any such loss, claim, damage, liability or action.

          (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such indemnifying party has been materially prejudiced by such failure (through the forfeiture of substantive rights or defenses). In case any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to

participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation.

          The indemnifying party under this Section 7 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 7, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (a) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (b) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

          (d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchaser on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Initial Purchaser on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Initial Purchaser on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Initial Purchaser, in each case as set forth in the Offering Memorandum or in this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Initial Purchaser and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such

untrue statement or omission. The Company and the Initial Purchaser agree that it would not be just and equitable if contributions pursuant to this subsection (d) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this subsection (d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Initial Purchaser shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities were offered exceeds the amount of any damages that the Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

          (e) The obligations of the Company under this Section 7 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Initial Purchaser within the meaning of the Securities Act; and the obligations of the Initial Purchaser under this Section 7 shall be in addition to any liability that the Initial Purchaser may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company and to each person, if any, who controls the Company within the meaning of the Securities Act.

          (f) The Initial Purchaser confirms and the Company acknowledges that the statements with respect to the offering of the Securities by the Initial Purchaser set forth in the first sentence of the second paragraph under the heading “No Prior Market” and in the first paragraph under the heading “Stabilization” under the section entitled “Plan of Distribution” in the Time of Sale Disclosure Package and in the Offering Memorandum are correct and constitute the only information concerning such Initial Purchaser furnished in writing to the Company by or on behalf of the Initial Purchaser specifically for inclusion in any Preliminary Offering Memorandum, the Time of Sale Disclosure Package, the Offering Memorandum or any Pricing Term Sheet.

     Section 8. Representations and Agreements to Survive Delivery. All representations, warranties, and agreements of the Initial Purchaser and the Company herein or in certificates delivered pursuant hereto, including but not limited to the agreements of the Initial Purchaser and the Company contained in Section 7 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Initial Purchaser or any controlling person thereof, or the Company or any of its officers, directors, or controlling persons, and shall survive delivery of, and payment for, the Securities to and by the Initial Purchaser hereunder.

     Section 9. Termination of this Agreement.

          (a) You, as the Initial Purchaser, shall have the right to terminate this Agreement by giving notice to the Company as hereinafter specified at any time at or prior to the

First Closing Date, and the option referred to in Section 3(b) hereof, if exercised, may be cancelled at any time prior to the Second Closing Date, if (i) the Company shall have failed, refused or been unable, at or prior to such Closing Date, to perform any agreement on its part to be performed hereunder, (ii) any condition of the Initial Purchaser’s obligations hereunder is not fulfilled, (iii) trading in the Company’s Common Stock shall have been suspended by the Commission or the Nasdaq Global Select Market or trading in securities generally on the Nasdaq Stock Market, New York Stock Exchange or the American Stock Exchange shall have been suspended, (iv) minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the Nasdaq Stock Market, New York Stock Exchange or the American Stock Exchange, by such exchange or by order of the Commission or any other governmental authority having jurisdiction, (v) a banking moratorium shall have been declared by federal or state or local authorities in the United States or Malaysia, (vi) there shall have occurred any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States or Malaysia, any declaration by the United States or Malaysia of a national emergency or war, any change in financial markets, any substantial change or development involving a prospective substantial change in United States or international political, financial or economic conditions, or any other calamity or crisis that, in your judgment, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Securities. Any such termination shall be without liability of any party to any other party except that the provisions of Section 4(g) and Section 7 hereof shall at all times be effective and shall survive such termination.

          (b) If you elect to terminate this Agreement as provided in this Section 9, the Company shall be notified promptly by you by telephone, confirmed by letter.

     Section 10. Default by the Company.

The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Initial Purchaser with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by the Initial Purchaser’s investment banking divisions. The Company acknowledges that the Initial Purchaser is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

The Company acknowledges and agrees that: (a) the Initial Purchaser has been retained solely to act as an initial purchaser in connection with the sale of the Securities and that no fiduciary, advisory or agency relationship between the Company and the Initial Purchaser has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether the Initial Purchaser has advised or is advising the Company on other matters; (b) the price and other terms of the Securities set forth in this Agreement were established by the Company following discussions and arms-length negotiations with the Initial Purchaser and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (c) it has been advised that the Initial Purchaser and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Initial Purchaser has no obligation to disclose such interest and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; (d) it has been advised that the Initial Purchaser is acting, in respect of the transactions contemplated by this Agreement, solely for the benefit of the Initial Purchaser and not on behalf of the Company; (e) it waives, to the fullest extent permitted by law, any claims it may have against the Initial Purchaser for breach of fiduciary duty or alleged breach of fiduciary duty in respect of any of the transactions contemplated by this Agreement and agrees, to the fullest extent permitted by law, that the Initial Purchaser shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.
