The Company will promptly advise the Representatives of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. (g) The Company will not, and will not permit any of its Affiliates to, resell any Securities or shares of Common Stock issued upon conversion thereof that have been acquired by any of them. (h) None of the Company, its Affiliates, or any person acting on its or their behalf (other than the Initial Purchasers) will, directly or indirectly, make offers or sales of any security, or solicit offers to buy any security, under circumstances that would require the registration of the Securities or Common Stock issuable upon conversion thereof under the Act. (i) None of the Company, its Affiliates, or any person acting on its or their behalf (other than the Initial Purchasers) will engage in any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with any offer or sale of the Securities in the United States. (j) So long as any of the Securities or the Common Stock issuable upon the conversion thereof are "restricted securities" within the meaning of Rule 144(a)(3) under the Act the Company will, during any period in which it is not subject to and in compliance with Section 13 or 15(d) of the Exchange Act, provide to each holder of such restricted securities and to each prospective purchaser (as designated by such holder) of such restricted securities, upon the request of such holder or prospective purchaser, any information required to be provided by Rule 144A(d)(4) under the Act. This covenant is intended to be for the benefit of the holders, and the prospective purchasers designated by such holders, from time to time of such restricted securities. (k) Any information provided by the Company to publishers of publicly available databases about the terms of the Securities shall include a statement that the Securities have not been registered under the Act and are subject to restrictions under Rule 144A under the Act. 13 (l) The Company will cooperate with the Representatives and use its best efforts to permit the Securities to be eligible for clearance and settlement through The Depository Trust Company. (m) The Company will reserve and keep available at all times, for so long as any Securities are outstanding and convertible, free of pre-emptive rights, the full number of shares of Common Stock issuable upon conversion of the Securities. (n) The Company will not for a period of 90 days following the Execution Time, without the prior written consent Banc of America Securities and Citigroup, directly or indirectly, offer, sell or contract to sell, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any Affiliate of the Company or any person in privity with the Company or any Affiliate of the Company), or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act in respect of, any shares of capital stock of the Company or any securities convertible into, or exercisable or exchangeable for, shares of capital stock of the Company (other than the Securities), or publicly announce an intention to effect any such transaction; provided, however, that (i) the Company may issue and sell Common Stock or securities convertible into or exchangeable for Common Stock pursuant to any employee stock option plan, stock ownership plan, deferred compensation plan, stock bonus plan, dividend reinvestment plan or other arrangement described in the Disclosure Package and the Final Memorandum of the Company and in effect at the Execution Time, (ii) the Company may issue Common Stock issuable upon the conversion of securities or the exercise of options or warrants outstanding at the Execution Time, and (iii) the Company may issue and sell Common Stock or securities convertible into or exchangable for Common Stock in connection with acquisition or business combination transactions. (o) The Company will not take, directly or indirectly, any action designed to or that has constituted or that might reasonably be expected to cause or result, under the Exchange Act or otherwise, in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities. (p) The Company agrees to pay the costs and expenses relating to the following matters: (i) the preparation of the Registration Rights Agreement and the preparation, printing or reproduction of the materials contained in the Disclosure Package and the Final Memorandum and each amendment or supplement to either of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the materials contained in the Disclosure Package and the Final Memorandum, and all amendments or supplements to either of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Securities; (iv) any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (v) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Securities; (vi) any registration or qualification of the Securities for offer and sale 14 under the securities or blue sky laws of the several states, and any other jurisdictions specified pursuant to Section 5(f) (including filing fees and the reasonable fees and expenses of counsel for the Initial Purchasers relating to such registration and qualification); (vii) the transportation and other expenses incurred by or on behalf of Company representatives in connection with presentations to prospective purchasers of the Securities; (viii) the fees and expenses of the Company's accountants and the fees and expenses of counsel (including local and special counsel) for the Company; and (ix) all other costs and expenses incident to the performance by the Company of their obligations hereunder. Except as provided in this Section 5(p) and Section 7, the Initial Purchasers shall pay their own expenses, including the fees and disbursements of their counsel. (q) Between the date hereof and the Closing Date, the Company will not do or authorize any act or thing that would result in an adjustment of the conversion price. (r) The Company will, for a period of twelve months following the Execution Time, furnish to the Representatives upon request (i) all reports or other communications (financial or other) generally made available to stockholders, and deliver to the Representatives as soon as they are available, copies of any reports and financial statements furnished to or filed with the Commission or any securities exchange on which any class of securities of the Company is listed and (ii) such additional information concerning the business and financial condition of the Company as the Representatives may from time to time reasonably request (such statements to be on a consolidated basis to the extent the accounts of the Company and its subsidiaries are consolidated in reports furnished to stockholders). (s) The Company will not take any action or omit to take any action (such as issuing any press release relating to any Securities without an appropriate legend) which may result in the loss by any of the Initial Purchases of the ability to rely on any stabilization safe harbor provided by the Financial Services Authority under the FSMA. (t) The Company will comply in all material respects with all applicable securities and other laws, rules, and regulations, including, without limitation, the Sarbanes-Oxley Act, and use its best efforts to cause the Company's directors and officers, in their capacities as such, to comply in all material respects with such laws, rules and regulations, including, without limitation, the provisions of the Sarbanes-Oxley Act. 6. Conditions to the Obligations of the Initial Purchasers. The obligations of the Initial Purchasers to purchase the Firm Securities and the Option Securities, as the case may be, shall be subject to the accuracy of the representations and warranties of the Company contained herein at the Execution Time, the Closing Date and any settlement date pursuant to Section 3 hereof, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions: (a) The Company shall have requested and caused Latham & Watkins, counsel for the Company, to furnish the Representatives its opinion, dated the Closing Date and substantially in the form attached hereto as Exhibit A. 15 (b) The Representatives shall have received from Cleary Gottlieb Steen & Hamilton LLP, counsel for the Initial Purchasers, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Indenture, the Registration Rights Agreement, the Disclosure Package, the Final Memorandum (as amended or supplemented at the Closing Date) and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters. (c) The Company shall have furnished to the Representatives a certificate of the Company, signed by (i) the President or the Chief Executive Officer and (ii) the principal financial officer or the principal accounting officer of the Company, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Disclosure Package and the Final Memorandum, any amendments or supplements thereto, and this Agreement and that: (i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; and (ii) since the date of the most recent financial statements included or incorporated by reference in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto), there has been no material adverse change in the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto). (d) At the Execution Time, the Company shall have requested and caused E&Y to furnish to the Representatives a "comfort" letter, dated as of the Execution Time and substantially in the form attached hereto as Exhibit B, and at the Closing Time, the Company shall have requested and caused E&Y to furnish to the Representatives a "bring-down comfort" letter, dated as of the Closing Date, reaffirming the statements made in the "comfort" letter, except that the specified date referred to shall be a date not more than three business days prior to the Closing Date. (e) At the Execution Time, the Company shall have requested and caused KPMG to furnish to the Representatives a "comfort" letter, dated as of the Execution Time and substantially in the form attached hereto as Exhibit C, and at the Closing Time, the Company shall have requested and caused KPMG to furnish to the Representatives a "bring-down comfort" letter, dated as of the Closing Date, reaffirming the statements made in the "comfort" letter, except that the specified date referred to shall be a date not more than three business days prior to the Closing Date. 16 (f) At the Execution Time, the Company shall have requested and caused KPMG to furnish to the Representatives a "comfort" letter relating to Inamed Corporation, dated as of the Execution Time and substantially in the form attached hereto as Exhibit D, and at the Closing Time, the Company shall have requested and caused KPMG to furnish to the Representatives a "bring-down comfort" letter, dated as of the Closing Date, reaffirming the statements made in the "comfort" letter, except that the specified date referred to shall be a date not more than three business days prior to the Closing Date. (g) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Disclosure Package (exclusive of any amendment or supplement thereto) and the Final Memorandum (exclusive of any amendment or supplement thereto), there shall not have been any change in the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto), the effect of which is, in the judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto). (h) The Securities shall have been designated as PORTAL-eligible securities in accordance with the rules and regulations of the NASD and the Securities shall be eligible for clearance and settlement through The Depository Trust Company.

(j) The Company shall have caused the shares of Common Stock initially issuable upon conversion of the Securities to be approved for listing, subject to issuance, on the New York Stock Exchange. (k) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request. If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder may be cancelled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing. 17 The documents required to be delivered by this Section 6 will be delivered at the office of counsel for the Initial Purchasers, at Cleary Gottlieb Steen & Hamilton LLP, One Liberty Plaza, New York, New York 10006, on the Closing Date. 7. Reimbursement of Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial Purchasers, the Company will reimburse the Initial Purchasers severally through Citigroup Global Markets Inc. on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities. 8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Initial Purchaser, the directors and officers of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Disclosure Package, the Final Memorandum, any Issuer Written Information or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities, or in any amendment or supplement thereto, 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, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Memorandum or the Final Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Initial Purchaser through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Company may otherwise have. (b) Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Company, each of its directors, each of its officers, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Initial Purchaser, but only with reference to written information relating to such Initial Purchaser furnished to the Company by or on behalf of such Initial Purchaser through the Representatives specifically for inclusion in the Preliminary Memorandum or the Final Memorandum or in any amendment or supplement thereto. This indemnity agreement will be in addition to any liability that any Initial Purchaser 18 may otherwise have. The Company acknowledges that (i) the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and (ii), under the heading "Plan of Distribution," the fifth and eighth paragraphs and the fifth and sixth sentences of the seventh paragraph related to compliance by the Initial Purchasers with applicable laws, stabilization and syndicate covering transactions and market-making transactions in the Preliminary Memorandum and the Final Memorandum constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or the Final Memorandum or in any amendment or supplement thereto. (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. It is understood, however, that the Company shall, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Initial Purchasers and controlling persons, which firm shall be designated in writing by the Representatives. Notwithstanding the indemnifying party's election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, 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 indemnified parties are actual or potential parties to such claim or action) 19 unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Initial Purchasers severally agree, in lieu of or supplemental to, respectively, indemnifying such indemnified party thereunder, to contribute to the amount paid or payable by such indemnified party as a result of the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively "Losses") to which the Company and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Initial Purchasers on the other from the offering of the Securities; provided, however, that in no case shall any Initial Purchaser be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Initial Purchasers severally shall contribute to the aggregate Losses in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses, but after deducting total discounts and commissions received by the Initial Purchasers) received by it, and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Act or the Exchange Act and each director and officer of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d). 9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal 20 amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the Company. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder. 10. Termination. This Agreement shall be subject to termination by the Representatives by notice to the Company prior to delivery of, and payment for, the Securities, if at any time prior to such delivery and payment (i) trading in the Company's Common Stock shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such exchange; (ii) a banking moratorium shall have been declared either by U.S. federal or New York State authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto). 11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Initial Purchasers or the Company or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 5(p), 7 and 8 hereof shall survive the termination or cancellation of this Agreement. 12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to (i) the Citigroup General Counsel (fax no.: (212) 816-7912) and confirmed to Citigroup at 388 Greenwich Street, New York, New York 10013, Attention: General Counsel, (ii) Banc of America Securities (fax no.: (646) 313-4803) and confirmed to it at 40 West 57th Street, NY1-040-27-01, New York, New York 10019, Attention: High Grade Transaction Management/Legal, and (iii) Morgan Stanley & Co.

This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the indemnified persons referred to in Section 8 hereof, and, except as expressly set forth in Section 5(j) hereof, no other person will have any right or obligation hereunder. 14. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Initial Purchasers, or any of them, with respect to the subject matter hereof. 15. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York. 16. Waiver of Jury Trial. The parties hereto hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. 17. No Fiduciary Duty. The Company hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm's-length commercial transaction between the Company, on the one hand, and the Initial Purchasers and any affiliate through which they may be acting, on the other, (b) the Initial Purchasers are acting as principal and not as an agent or fiduciary of the Company and (c) the Company's engagement of the Initial Purchasers in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Initial Purchasers has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto. 18.
