(g) The Company shall have furnished to the Initial Purchaser (i) a letter of AA (the "AA Bring-Down Letter"), (ii) a letter of D&T (the "D&T Bring-Down Letter") and (iii) a letter of KPMG (the "KPMG Bring-Down Letter" and, together with the AA Bring-Down Letter and the D&T Bring-Down Letter, the "Bring-Down Letters"), in each case addressed to the Initial Purchaser and dated the Closing Date (A) confirming that they are independent public accountants with respect to the Company and CBHS, in the case of the AA Bring-Down Letter, Merit, in the case of the D&T Bring-Down Letter, and HAI, in the case of the KPMG Bring-Down Letter, in each case within the meaning of Rule 101 of the Code of Professional Conduct of the AICPA and its interpretations and rulings thereunder, (B) stating, as of the date of the applicable Bring-Down Letter (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Offering Memorandum, as of a date not more than three business days prior to the date of the applicable Bring-Down Letter), that the conclusions and findings of such accountants with respect to the financial information and other matters covered by the applicable Initial Letter are accurate and (C) confirming in all material respects the conclusions and findings set forth in the applicable Initial Letter. 19 (h) The Company shall have furnished to the Initial Purchaser a certificate, dated the Closing Date, of its chief executive officer and its chief financial officer stating that (A) such officers have carefully examined the Offering Memorandum, (B) in their opinion, the Offering Memorandum, as of its date, did not include any untrue statement of a material fact and did not omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and since the date of the Offering Memorandum, no event has occurred which should have been set forth in a supplement or amendment to the Offering Memorandum so that the Offering Memorandum (as so amended or supplemented) would not include any untrue statement of a material fact and would not omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading and (C) as of the Closing Date, the representations and warranties of the Company in this Agreement are true and correct in all material respects, the Company has complied, in all material respects, with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder on or prior to the Closing Date, and subsequent to the date of the most recent financial statements contained in the Offering Memorandum, there has been no change in the financial position or results of operation of the Company, Merit and their respective subsidiaries, taken as a whole, that has had or could reasonably be expected to have a Material Adverse Effect, or any change, or any development including a prospective change, in or affecting the condition (financial or otherwise), results of operations, business or prospects of the Company, Merit and their subsidiaries, taken as a whole, that has had or could reasonably be expected to have a Material Adverse Effect.

(l) There shall not have occurred any invalidation of Rule 144A under the Securities Act by any court or any withdrawal or proposed withdrawal of any rule or regulation under the Securities Act or the Exchange Act by the Commission or any amendment or proposed amendment thereof by the Commission which in the judgment of the Initial Purchaser would materially impair the ability of the Initial Purchaser to purchase, hold or effect resales of the Securities as contemplated hereby. (m) Subsequent to the execution and delivery of this Agreement or, if earlier, the dates as of which information is given in the Offering Memorandum (exclusive of any amendment or supplement thereto), there shall not have been any change in the capital 20 stock or long-term debt or any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), results of operations, business or prospects of the Company, Merit and their respective subsidiaries taken as a whole, the effect of which, in any such case described above, is, in the reasonable judgment of the Initial Purchaser, so material and adverse as to make it impracticable or inadvisable to proceed with the sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement and the Offering Memorandum (exclusive of any amendment or supplement thereto). (n) No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any governmental agency or body which would, as of the Closing Date, prevent the issuance or sale of the Securities; and no injunction, restraining order or order of any other nature by any federal or state court of competent jurisdiction shall have been issued as of the Closing Date which would prevent the issuance or sale of the Securities. (o) Subsequent to the execution and delivery of this Agreement (i) no downgrading shall have occurred in the rating accorded the Securities or any of the Company's other debt securities or preferred stock by any "nationally recognized statistical rating organization", as such term is defined by the Commission for purposes of Rule 436(g)(2) of the rules and regulations of the Commission under the Securities Act and (ii) no such organization shall have publicly announced that it has under surveillance or review (other than an announcement with positive implications of a possible upgrading), its rating of the Securities or any of the Company's other debt securities or preferred stock.

(q) All conditions to the consummation of each of the Transactions, other than the offering of the Securities, shall have been satisfied and each of such Transactions shall be consummated substantially concurrently with the sale of the Securities hereunder. 21 All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Initial Purchaser. 6.

Indemnification. (a) The Company shall indemnify and hold harmless the Initial Purchaser, its affiliates, their respective officers, directors, employees, representatives and agents, and each person, if any, who controls the Initial Purchaser within the meaning of the Securities Act or the Exchange Act (collectively referred to for purposes of this Section 8(a) and Section 9 as the Initial Purchaser), from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, without limitation, any loss, claim, damage, liability or action relating to purchases and sales of the Securities), to which the Initial Purchaser may become subject, whether commenced or threatened, under the Securities Act, the Exchange Act, any other federal or state statutory law or regulation, at common law or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum or the Offering Memorandum or in any amendment or supplement thereto or in any information provided by the Company pursuant to Section 4(e) or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and shall reimburse the Initial Purchaser promptly upon demand for any legal or other expenses reasonably incurred by the Initial Purchaser in connection with investigating or defending or preparing to defend against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action as such expenses are incurred; 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 in or omission or alleged omission from any of such documents in reliance upon and in conformity with the Initial Purchaser's Information; and provided, further, that with respect to any such untrue statement in or omission from the Preliminary Offering Memorandum, the indemnity agreement contained in this Section 8(a) shall not inure to the benefit of the Initial Purchaser to the extent that the sale to the person asserting any such loss, claim, damage, liability or action was an initial resale by the Initial Purchaser and any such loss, claim, damage, liability or action of or with respect to the Initial Purchaser results from the fact that both (A) to the extent required by applicable law or Section 2(e), a copy of the Offering Memorandum was not sent or given to such person at or prior to the written confirmation of the sale of such Securities to such person and (B) the untrue statement in or omission from the Preliminary Offering Memorandum was corrected in the Offering Memorandum unless, in either case, such failure to deliver the Offering Memorandum was a result of non-compliance by the Company with Section 4(b). (b) The Initial Purchaser shall indemnify and hold harmless the Company, its affiliates, their respective officers, directors, employees, representatives and agents, and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act (collectively referred to for purposes of this Section 8(b) and Section 9 as the Company), from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company may become subject, whether commenced or threatened, under the Securities Act, the Exchange Act, any other federal or state statutory law or regulation, at common law or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum or the Offering Memorandum or in any amendment or supplement thereto or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with the Initial Purchaser's Information, and shall 23 reimburse the Company promptly upon demand for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending or preparing to defend against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action as such expenses are incurred. 24 (c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party pursuant to Section 8(a) or 8(b), notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate in the defense of such claim or action and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that an indemnified party shall have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel for the indemnified party will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based upon advice of counsel to the indemnified party) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (3) a conflict or potential conflict exists (based upon advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (4) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm of attorneys (in addition to any local counsel) at any one time for all such indemnified party or parties. Each indemnified party, as a condition of the indemnity agreements contained in Sections 8(a) and 8(b), shall use all reasonable efforts to cooperate with the indemnifying party in the defense of any such action or claim. No indemnifying party shall be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. 25 The obligations of the Company and the Initial Purchaser in this Section 8 and in Section 9 are in addition to any other liability that the Company or the Initial Purchaser, as the case may be, may otherwise have, including in respect of any breaches of representations, warranties and agreements made herein by any such party. 9. Contribution. If the indemnification provided for in Section 8 is unavailable or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be 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, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, 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 with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Securities purchased under this Agreement (before deducting expenses) received by or on behalf of the Company, on the one hand, and the total discounts and commissions received by the Initial Purchaser with respect to the Securities purchased under this Agreement, on the other, bear to the total gross proceeds from the sale of the Securities under this Agreement, in each case as set forth in the table on the cover page of the Offering Memorandum. 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 the Company or information supplied by the Company, on the one hand, or to the Initial Purchaser's Information, 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 Purchaser agree that it would not be just and equitable if contributions pursuant to this Section 9 were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 9 shall be deemed to include, for purposes of this Section 9, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending or preparing to defend any such action or claim. Notwithstanding the provisions of this Section 9, the Initial Purchaser shall not be required to contribute any amount in excess of the amount by which the total discounts and commissions received by the Initial Purchaser with respect to the Securities purchased by it under this Agreement exceeds the amount of any damages that the Initial Purchaser has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission.
