         Stock, under the captions "Material U.S. Federal Income and Estate Tax
         Considerations to Non-U.S. Holders", "Business -- Government
         Regulation", "Business -- Environmental Matters", "Business -- Leases",
         "Description of Indebtedness" and "Underwriting", insofar as they

         governmental authorities or threatened by others;

                  (xiv) The Company is not and, after giving effect to the

                  (xv) The financial statements included in the Registration
         Statement and the Pricing Prospectus and the Prospectus (taken

         in all material respects, the financial position of the Company and
         its subsidiaries and ARC and its subsidiaries as of the dates shown
         and their results of operations and cash flows for the periods shown,
         and such financial statements have been prepared in conformity with
         the generally accepted accounting principles in the United States
         applied on a consistent basis and the schedules included in each
         Registration Statement present fairly, in all material respects, the
         information required to be stated therein; and the assumptions used in
         preparing the pro forma financial statements included in the
         Registration Statement and the Pricing Prospectus and the Prospectus
         provide a reasonable basis for presenting the significant effects
         directly attributable to the transactions or events described therein,
         the related pro forma adjustments, in all material respects, give
         appropriate effect to those assumptions, and the pro forma columns
         therein reflect, in all material respects, the proper application of
         those adjustments to the corresponding historical financial statement
         amounts;

                  (xvi) (1) Ernst & Young LLP, who have certified certain
         financial statements of the (A) Company and its subsidiaries and (B)
         CMCP -- Properties, Inc and its subsidiaries, (2) KPMG LLP, who have
         certified certain financial statements of (A) Alterra Healthcare
         Corporation and (B) ARC and its subsidiaries and (3) Deloitte & Touche
         LLP, are each independent public accountants as required by the Act
         and the rules and regulations of the Commission thereunder;

                  (xvii) The Company maintains a system of internal control
         over financial reporting (as such term is defined in Rule 13a-15(f)
         under the Exchange Act) that complies and upon consummation of the ARC
         Merger will continue to comply with the requirements of the Exchange
         Act and has been designed by the Company's principal executive officer
         and principal financial officer, or under their supervision, to
         provide reasonable assurance regarding the reliability of financial
         reporting and the preparation of financial statements for external
         purposes in accordance with generally accepted accounting principles.
         The Company's internal control over financial reporting is, and upon
         consummation of the ARC Merger will remain, effective and the Company
         is not aware of any material weaknesses in its internal control over
         financial reporting. Except as is otherwise set forth in the
         Registration Statement, the Company is not aware of any weaknesses in
         ARC's internal control over financial reporting that would have a
         material weaknesses in the Company's internal control over financial
         reporting upon the consummation of the ARC Merger;

                  (xviii) Since the date of the latest audited financial
         statements of the Company included in the Pricing Prospectus and the
         Prospectus, there has been no change in the Company's internal control
         over financial reporting that has materially affected, or is
         reasonably likely to materially affect, the Company's internal control
         over financial reporting. Since the date of the latest audited
         financial statements of ARC included in the Pricing Prospectus and the
         Prospectus, the Company is not aware of any change in ARC's internal
         control over financial reporting that has materially affected, or is
         reasonably likely to materially affect, the internal control over
         financial reporting of ARC or the Company upon the consummation of the
         ARC Merger;

                  (xix) The Company maintains disclosure controls and
         procedures (as such term is defined in Rule 13a-15(e) under the
         Exchange Act) that comply with the requirements of the Exchange Act
         and upon consummation of the ARC Merger will continue to comply with
         the requirements of the Exchange Act; such disclosure controls and
         procedures have been designed to ensure that material information
         relating to the Company and its subsidiaries is made known to the
         Company's principal executive officer and principal financial officer
         by others within those entities; and such disclosure controls and
         procedures are effective and upon consummation of the ARC Merger will
         continue to be effective;

                  (xx) Each of the Company and its subsidiaries (x) has all
         certificates, consents, exemptions, orders, permits, licenses,
         authorizations, or other approvals (each, an "Authorization") of and
         from, and has made all declarations and filings with, all federal,
         state, local and other governmental authorities, all self-regulatory
         organizations and all courts and other tribunals, necessary or
         required to engage in the business currently conducted by it in the
         manner described in the Pricing Prospectus and the Prospectus; (y) all
         such Authorizations are valid and in full force and effect; and (z)
         each of the Company and its subsidiaries is in compliance in with the
         terms and conditions of all such Authorizations and with the rules and
         regulations of the regulatory authorities and governing bodies having
         jurisdiction with respect thereto, except, with respect to (x), (y)
         and (z), as would not, individually or in the aggregate, reasonably be
         expected to have a Material Adverse Effect; and there are no
         proceedings pending or, to the best of the Company's knowledge,
         threatened, to revoke, cancel or terminate such Authorizations and
         applications and the Company is not aware of any basis on which such
         Authorizations could not be renewed or, in the case of applications,
         will not be issued without contest;

                  (xxi) Each of the Company and its subsidiaries owns or
         possesses or has the right to use the licenses, material copyrights,
         know-how (including trade secrets and other unpatented and/or
         unpatentable proprietary or confidential information, systems or
         procedures), domain names, trademarks, service marks and trade names
         (collectively, the "Intellectual Property") presently employed by it
         in connection with its operations, except where the failure to own or
         possess or have the right to use such Intellectual Property would not,
         individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect; and neither the Company nor any of its
         subsidiaries has received any notice of infringement of or conflict
         with asserted rights of others with respect to the foregoing. To the
         knowledge of the Company and its subsidiaries, the use of such
         Intellectual Property in connection with the business and operations
         of the Company and its subsidiaries as described in the Pricing
         Prospectus does not infringe on the rights of any person;

                  (xxii) All tax returns required to be filed by the Company
         and its subsidiaries in all jurisdictions have been timely and duly
         filed, other than those filings being contested in good faith and
         except where the failure to file would not, individually or in the
         aggregate, have a Material Adverse Effect. There are no tax returns of
         the Company or its subsidiaries that are currently being audited by
         state, local or federal taxing authorities or agencies (and with
         respect to which the Company or its subsidiaries has received notice),
         where the findings of such audit could reasonably be expected to
         result in a Material Adverse Effect. All taxes, including withholding
         taxes, penalties and interest, assessments, fees and other charges due
         or claimed to be due from such entities, have been paid, other than
         those being contested in good faith and for which adequate reserves
         have been provided or those currently payable without penalty or
         interest or those that could not reasonably be expected to result in a
         Material Adverse Effect;

                  (xxiii) Except as disclosed in the Pricing Prospectus and the
         Prospectus, each of the Company and its subsidiaries maintains
         insurance covering its properties, operations, personnel and
         businesses which insures against such losses and risks as are adequate
         in accordance with its reasonable business judgment to protect the
         Company and its subsidiaries and their businesses;

                  (xxiv) Except as disclosed in the Pricing Prospectus and the
         Prospectus, there are no material business relationships or related
         party transactions which would be required to be disclosed therein by
         Item 404 of Regulation S-K of the Commission and such business
         relationship or related party transaction described therein is a fair
         and accurate description in all material respects of the relationships
         and transactions so described;

                  (xxv) Each of the Company and its subsidiaries is in
         compliance in all material respects with all presently applicable
         provisions of the Employee Retirement Income Security Act of 1974, as
         amended, including the regulations and published interpretations
         thereunder ("ERISA"); no "reportable event" (as defined in ERISA) has
         occurred with respect to any "pension plan" (as defined in ERISA) for
         which the Company or any of its subsidiaries would have any material
         liability; each of the Company and its subsidiaries has not incurred
         and does not reasonably expect to incur liability under (i) Title IV
         of ERISA with respect to termination of, or withdrawal from, any
         "pension plan" or (ii) Section 412 or 4971 of the Internal Revenue
         Code of 1986, as amended, including the regulations and published
         interpretations thereunder (the "Code"); and each "pension plan" for
         which the Company or any of its subsidiaries would have any material
         liability, that is intended to be qualified under Section 401(a) of
         the Code is so qualified in all material respects and nothing has
         occurred, whether by action or by failure to act, which would cause
         the loss of such qualification;

                  (xxvi) Each of the Company and its subsidiaries is and has
         been in compliance with all applicable Environmental Laws (as defined
         below), except where failure to comply would not, individually or in
         the aggregate, reasonably be expected to have a Material Adverse
         Effect. To the best of the Company's knowledge, there has been no
         material seepage, leak, escape, leach, discharge, injection, release,
         emission, spill, pumping, pouring, emptying, dumping, disposing, or
         migrating or any threat thereof of any Hazardous Material (as defined
         below) on, in, under, or from any real property referred to in the
         Pricing Prospectus and the Prospectus which requires any disclosure,
         investigation, cleanup, remediation, monitoring, maintenance,
         abatement or deed or use restriction, or which will give rise to any
         other costs or liabilities to the Company or its subsidiaries under
         any Environmental Laws. There are no past, present or, to the
         Company's knowledge, reasonably anticipated future events, conditions,
         circumstances, activities, practices, actions, omissions or plans that
         could reasonably be expected to interfere with or prevent compliance
         by the Company or its subsidiaries with Environmental Laws, or that
         could reasonably be expected to give rise to any material costs or
         liabilities, which could reasonably be expected to, either
         individually or in the aggregate, have a Material Adverse Effect.
         There are no judicial or administrative proceedings of an
         environmental nature pending, or to the best of the Company's
         knowledge, threatened against the Company or its subsidiaries which
         could reasonably be expected to be material to the business or
         financial condition of the Company and its subsidiaries to involve
         potential damages, monetary sanctions, capital expenditures, deferred
         charges or charges to income exceeding ten percent of the current
         assets of the Company and its subsidiaries or to involve potential
         monetary sanctions of $100,000.00 or more. None of the Company or its
         subsidiaries has received notice from any governmental agency or body
         or other person of any actual or alleged violation of or actual or
         alleged liability under any Environmental Law, and does not otherwise
         have knowledge of, any occurrence, condition or circumstance which,
         with notice, passage of time, or failure to act, would give rise to
         any claim or liability under or pursuant to any Environmental Law. The
         Company or its subsidiaries, has not arranged for the disposal of any
         Hazardous Material at, or transported any Hazardous Material to, any
         site which could result in material liability for the Company or its
         subsidiaries. The Company or its subsidiaries has not entered into any
         agreement relating to any alleged violation of any Environmental Law
         or any actual or alleged release or threatened release or cleanup at
         any location of any Hazardous Materials. As used herein,
         "Environmental Law" means any federal, state, local or foreign law,
         statute, ordinance, rule, regulation, order, decree, judgment,
         injunction, permit, license, authorization or other binding
         requirement, or common law, relating to health, safety or the
         protection, cleanup or restoration of the environment or natural
         resources, including, but not limited to, those relating to the
         distribution, processing, generation, treatment, storage, disposal,
         transportation, other handling or release or threatened release of
         Hazardous Materials, and "Hazardous Materials" means any material
         (including, without limitation, pollutants, contaminants, hazardous or
         toxic substances or wastes, asbestos, silica, mixed dust, petroleum or
         constituents thereof, bacteria, radon, mold or fungi) that is
         regulated by or may give rise to liability under any Environmental
         Law. The Company has provided you copies of all materials and
         potentially material environmental studies, investigations, reports or
         assessments concerning the Company, or any currently or previously
         owned or leased properties within its possession or control. In the
         ordinary course of its business, the Company conducts a periodic
         review of the effect of the Environmental Laws on its business,
         operations and properties, in the course of which it identifies and
         evaluates associated costs and liabilities (including, without
         limitation, any capital or operating expenditures required for
         cleanup, closure of properties or compliance with the Environmental
         Laws or any permit, license or approval, any related constraints on
         operating activities and any potential liabilities to third parties);

                  (xxvii) The Registration Statement, the Pricing Prospectus,
         the Prospectus and any Preliminary Prospectus comply, and any further
         amendments or supplements thereto will comply, with any applicable
         laws or regulations of foreign jurisdictions in which the Pricing
         Prospectus, the Prospectus or any Preliminary Prospectus, as amended
         or supplemented, if applicable, are distributed in connection with the
         Directed Share Program. No consent, approval, authorization or order
         of, or filing or registration with, any court or governmental agency
         or body, other than such as have been obtained, is required under the
         securities laws and regulations of any foreign jurisdiction in which
         the Directed Shares are offered or sold outside the United States;

                  (xxviii) At the time of filing the Initial Registration
         Statement the Company was not and is not an "ineligible issuer," as
         defined under Rule 405 under the Act; and

                  (xxix) All of the representations and warranties of ARC and
         its subsidiaries in the ARC Merger Agreement are true and correct
         except as qualified therein.

         (b) The Selling Stockholder represents and warrants to, and agrees
with, each of the Underwriters and the Company that:

                  (i) All consents, approvals, authorizations and orders
         necessary for the execution and delivery by the Selling Stockholder of
         this Agreement and the Power of Attorney and the Custody Agreement
         hereinafter referred to, and for the sale and delivery of the Shares
         to be sold by the Selling Stockholder hereunder, have been obtained;
         and the Selling Stockholder has all necessary corporate power and
         authority to enter into this Agreement, the Power of Attorney and the
         Custody Agreement and to sell, assign, transfer and deliver the Shares
         to be sold by the Selling Stockholder hereunder;

                  (ii) The sale of the Shares to be sold by the Selling
         Stockholder hereunder and the compliance by the Selling Stockholder
         with all of the provisions of this Agreement, the Power of Attorney
         and the Custody Agreement and the consummation of the transactions
         herein and therein contemplated will not conflict with or result in a
         breach or violation of any of the terms or provisions of, or
         constitute a default under, (x) any statute, indenture, mortgage, deed
         of trust, loan agreement or other agreement or instrument to which the
         Selling Stockholder is a party or by which the Selling Stockholder is
         bound or to which any of the property or assets of the Selling
         Stockholder is subject, (y) the terms of the Certificate of
         Registration for an Exempted Partnership dated February 26, 1999
         issued by the Registrar of Companies in respect of the Selling
         Stockholder and the Second Amended and Restated Partnership Agreement
         of the Selling Stockholder dated January 1, 2005 or (z) any statute or
         any order, rule or regulation of any court or governmental agency or
         body having jurisdiction over the Selling Stockholder or the property
         of the Selling Stockholder, except in the case of clauses (x) and (z)
         for such conflicts, breaches, defaults or violations that would not,
         individually or in the aggregate, reasonably be expected to have a
         material adverse effect on the validity of the Shares to be sold by
         the Selling Stockholder or on the ability of the Selling Stockholder
         to deliver good and valid title to such Shares;

                  (iii) The Selling Stockholder has, and immediately prior to
         the Time of Delivery (as defined in Section 4 hereof) the Selling
         Stockholder will have, good and valid title to the Shares to be sold
         by the Selling Stockholder hereunder, free and clear of all liens,
         encumbrances, equities or claims; and, upon delivery of such Shares
         and payment therefor pursuant hereto, good and valid title to such
         Shares, free and clear of all liens, encumbrances, equities or claims,
         will pass to the several Underwriters;

                  (iv) The Selling Stockholder has not taken and will not take,
         directly or indirectly, any action which is designed to or which has
         constituted or which might reasonably be expected to cause or result
         in stabilization or manipulation of the price of any security of the
         Company to facilitate the sale or resale of the Shares;

                  (v) To the extent that any statements or omissions made in the

         with written information furnished to the Company by the Selling
         Stockholder concerning the Selling Stockholder expressly for use
         therein, the Pricing Disclosure Package, as of the Applicable Time, did
         not include any untrue statement of a material fact or omit to state
         any material fact necessary in order to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading; each Issuer Free Writing Prospectus listed on Schedule
         III(a) or Schedule III(b) hereto, to the extent that any statements or
         omissions made therein are made in reliance upon and in conformity with
         written information furnished to the Company by the Selling Stockholder
         concerning the Selling Stockholder expressly for use therein, does not
         conflict with the information contained in the Registration Statement,
         the Pricing Prospectus or the Prospectus and each such Issuer Free

         the Registration Statement, any Preliminary Prospectus, the Pricing
         Disclosure Package, the Prospectus or any amendment or supplement

         Pricing Disclosure Package, the Prospectus and any further amendments
         or supplements to the Registration Statement, the Pricing Disclosure
         Package or the Prospectus, when they become effective or are filed with

         other applicable form or statement specified by Treasury Department

                  (viii) Certificates in negotiable form representing all of
         the Shares to be sold by the Selling Stockholder hereunder have been
         placed in custody under a Custody Agreement, in the form heretofore
         furnished to you (the "Custody Agreement"), duly executed and
         delivered by the Selling Stockholder to American Stock Transfer &
         Trust Company, as custodian (the "Custodian"), and the Selling
         Stockholder has duly executed and delivered a Power of Attorney, in
         the form heretofore furnished to you (the "Power of Attorney"),
         appointing Mark J. Schulte, Stanley Young and Deborah C. Paskin, and
         each of them, as the Selling Stockholder's attorneys-in-fact (the
         "Attorneys-in-Fact") with authority to execute and deliver this
         Agreement on behalf of the Selling Stockholder, to determine the
         purchase price to be paid by the Underwriters to the Selling

         custody for the Selling Stockholder under the Custody Agreement are
         subject to the interests of the Underwriters hereunder; the
         arrangements made by the Selling Stockholder for such custody, and the
         appointment by the Selling Stockholder of the Attorneys-in-Fact by the
         Power of Attorney, are to that extent irrevocable; the obligations of
         the Selling Stockholder hereunder shall not be terminated by operation
         of law; if the Selling Stockholder should be dissolved, or if any
         other such event should occur, before the delivery of the Shares
         hereunder, certificates representing the Shares shall be delivered by
         or on behalf of the Selling Stockholder in accordance with the terms
         and conditions of this Agreement and the Custody Agreement; and
         actions taken by the Attorneys-in-Fact pursuant to the Power of
         Attorney shall be as valid as if such dissolution or other event had
         not occurred, regardless of whether or not the Custodian, the
         Attorneys-in-Fact, or any of them, shall have received notice of such
         dissolution or other event;

                  (x) The Selling Stockholder shall execute and deliver to the
         Underwriters, a lock-up agreement in the form attached hereto as Annex
         I which shall be in full force and effect; and

                  (xi) The Selling Stockholder is not prompted to sell its
         Shares by any information concerning the Company or any subsidiary of
         the Company, ARC or any of its subsidiaries which is not set forth in
         the Pricing Disclosure Package and the Prospectus.

         2. Subject to the terms and conditions herein set forth, (a) the
Company and the Selling Stockholder agrees, severally and not jointly, to sell
to each of the Underwriters, and each of the Underwriters agrees, severally and
not jointly, to purchase from the Company and the Selling Stockholder, at a
purchase price per share of $38.1175, the number of Firm Shares (to be adjusted
by you so as to eliminate fractional shares, provided that the total number of
Firm Shares shall not be reduced by such adjustment) determined by multiplying
the aggregate number of Firm Shares to be sold by the Company and the Selling
Stockholder as set forth opposite their respective names in Schedule II hereto
by a fraction, the numerator of which is the aggregate number of Firm Shares to
be purchased by such Underwriter as set forth opposite the name of such
Underwriter in Schedule I hereto and the denominator of which is the aggregate
number of Firm Shares to be purchased by all of the Underwriters from the
Company and the Selling Stockholder hereunder and (b) in the event and to the
extent that the Underwriters shall exercise the election to purchase Optional
Shares as provided below, the Selling Stockholder agrees to sell to each of the
Underwriters, and each of the Underwriters agrees, severally and not jointly, to
purchase from the Selling Stockholder, at the purchase price per share set forth
in clause (a) of this Section 2, that portion of the number of Optional Shares
as to which such election shall have been exercised (to be adjusted by you so as
to eliminate fractional shares, provided that the total number of shares subject
to such election shall not be reduced by such adjustment) determined by
multiplying such number of Optional Shares by a fraction, the numerator of which
is the maximum number of Optional Shares which such Underwriter is entitled to
purchase as set forth opposite the name of such Underwriter in Schedule I hereto
and the denominator of which is the maximum number of Optional Shares that all
of the Underwriters are entitled to purchase hereunder.

         The Selling Stockholder hereby grants to the Underwriters the right to
purchase at their election up to 2,885,415 Optional Shares, at the purchase
price per share set forth in the paragraph above, for the sole purpose of
covering sales of shares in excess of the number of Firm Shares, provided that
the purchase price per Optional Share shall be reduced by an amount per share
equal to any dividends or distributions declared by the Company and payable on
the Firm Shares but not payable on the Optional Shares. Any such election to
purchase Optional Shares may be exercised only by written notice from you to
the Selling Stockholder, given within a period of 30 calendar days after the
date of this Agreement and setting forth the aggregate number of Optional
Shares to be purchased and the date on which such Optional Shares are to be
delivered, as determined by you but in no event earlier than the First Time of
Delivery (as defined in Section 4 hereof) or, unless you and the Selling
Stockholder otherwise agree in writing, earlier than two or later than ten
business days after the date of such notice.

         3. Upon the authorization by you of the release of the Firm Shares,
the several Underwriters propose to offer the Firm Shares for sale upon the
terms and conditions set forth in the Prospectus.

         4. (a) The Shares to be purchased by each Underwriter hereunder, in
definitive form, and in such authorized denominations and registered in such
names as Goldman, Sachs & Co. may request upon at least forty-eight hours' prior
notice to the Company and the Selling Stockholder shall be delivered by or on
behalf of the Company and the Selling Stockholder to Goldman, Sachs & Co.,
through the facilities of the Depositary Trust Company for the account of such
Underwriter, against payment by or on behalf of such Underwriter of the purchase
price therefor by wire transfer of Federal (same-day) funds to the account
specified by the Company and the Selling Stockholder to Goldman, Sachs & Co. at
least forty-eight hours in advance. The Company will cause the certificates
representing the Shares to be made available for checking and packaging at least
twenty-four hours prior to the Time of Delivery (as defined below) with respect
thereto at the office of Goldman, Sachs & Co., 85 Broad Street, New York, New
York 10004 (the "Designated Office"). The time and date of such delivery and
payment shall be, with respect to the Firm Shares, 9:30 a.m., New York time, on
July 25, 2006 or such other time and date as Goldman, Sachs & Co. and the
Company may agree upon in writing, and, with respect to the Optional Shares,
9:30 a.m., New York time, on the date specified by Goldman, Sachs & Co. in the
written notice given by Goldman, Sachs & Co. of the Underwriters' election to
purchase such Optional Shares, or such other time and date as Goldman, Sachs &
Co. and the Company may agree upon in writing. Such time and date for delivery
of the Firm Shares is herein called the "First Time of Delivery", such time and
date for delivery of the Optional Shares, if not the First Time of Delivery, is
herein called the "Second Time of Delivery", and each such time and date for
delivery is herein called a "Time of Delivery".

         (b) The documents to be delivered at each Time of Delivery by or on
behalf of the parties hereto pursuant to Section 8 hereof, including the cross
receipt for the Shares and any additional documents requested by the

information" filed or required to be filed pursuant to Rule 433(d) under the
Act, 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 each Underwriter
for any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating or defending any such action or claim 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 or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in the Registration Statement, any
Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any
amendment or supplement thereto, or any Issuer Free Writing Prospectus, in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter through Goldman, Sachs & Co. or Lehman Brothers Inc.
expressly for use therein.

         (b) The Selling Stockholder will indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the Act or
otherwise, 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
Prospectus, the Registration Statement, the Pricing Prospectus or the
Prospectus, or any amendment or supplement thereto or any Issuer Free Writing
Prospectus 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 Prospectus, the
Registration Statement, the Pricing Prospectus or the Prospectus or any such
amendment or supplement thereto, or any Issuer Free Writing Prospectus, in
reliance upon and in conformity with written information furnished to the
Company by the Selling Stockholder concerning the Selling Stockholder expressly
for use therein; and will reimburse each Underwriter for any legal or other
expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Selling Stockholder shall 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 an untrue statement or alleged untrue statement
or omission or alleged omission made in any Preliminary Prospectus, the
Registration Statement, the Pricing Prospectus or the Prospectus, or any
amendment or supplement thereto, or any Issuer Free Writing Prospectus, in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter through Goldman, Sachs & Co. or Lehman Brothers Inc.
expressly for use therein; provided, further, that the indemnification and
contribution liabilities of the Selling Stockholder pursuant to this Agreement
shall not exceed the product of the number of Shares sold by the Selling
Stockholder (including any Optional Shares) and the initial public offering
price per share of the Shares as set forth in the Prospectus. The written
information furnished to the Company by the Selling Stockholder concerning the
Selling Stockholder expressly for use in any Preliminary Prospectus, the
Registration Statement, the Pricing Prospectus or the Prospectus or any such
amendment or supplement thereto, or any Issuer Free Writing Prospectus is the
information regarding the Selling Stockholder set forth in the table appearing
under the heading "Principal Stockholders and Selling Stockholder" and
footnotes 4, 5 and 6 thereto.

         (c) Each Underwriter will indemnify and hold harmless the Company and
the Selling Stockholder against any losses, claims, damages or liabilities to
which the Company or the Selling Stockholder may become subject, under the Act
or otherwise, 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
Prospectus, the Registration Statement, the Pricing Prospectus or the
Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing
Prospectus 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 Prospectus, the
Registration Statement, the Pricing Prospectus or the Prospectus or any
amendment or supplement thereto, or any Issuer Free Writing Prospectus, in
reliance upon and in conformity with written information furnished to the
Company by such Underwriter through Goldman, Sachs & Co. or Lehman Brothers
Inc. expressly for use therein; and will reimburse the Company and the Selling
Stockholder for any legal or other expenses reasonably incurred by the Company
or the Selling Stockholder in connection with investigating or defending any
such action or claim as such expenses are incurred.

         (d) Promptly after receipt by an indemnified party under subsection
(a), (b) or (c) 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 failure to so notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. 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 therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
subsection for any legal expenses of other counsel or any other expenses, in
each case subsequently incurred by such indemnified party, in connection with
the defense thereof other than reasonable costs of investigation.
Notwithstanding anything contained herein to the contrary, if indemnity may be
sought pursuant to subsection (g) hereof in respect of a claim or action
referred to in Section subsection (g), then in addition to such separate firm
for the indemnified parties, the indemnifying party shall be liable for the
fees and expenses of not more than one separate firm (in addition to any local
counsel) for the Lehman Brothers Entities (as defined in subsection (g)) for
the defense of any loss, claim, damage, liability or action arising out of the
Directed Share Program. No indemnifying party shall, without the written
consent of the indemnified party, effect the settlement or compromise of, or
consent to the entry of any judgment with respect to, any pending or threatened
action or claim in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from
all liability arising out of such action or claim and (ii) 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.

         (e) If the indemnification provided for in this Section 9 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a), (b) or (c) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities
(or actions in respect thereof) in such proportion as is appropriate to reflect
the relative benefits received by the Company and the Selling Stockholder on
the one hand and the Underwriters on the other from the offering of the Shares.
If, however, the allocation provided by the immediately preceding sentence is
not permitted by applicable law or if the indemnified party failed to give the
notice required under subsection (d) above, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but
also the relative fault of the Company and the Selling Stockholder on the one
hand and the Underwriters on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company and the Selling
Stockholder on the one hand and the Underwriters 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 and the Selling Stockholder
bear to the total underwriting discounts and commissions received by the
Underwriters, in each case as set forth in the table on the cover page of the
Prospectus. 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 Selling Stockholder on the one hand
or the Underwriters on the other and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company, the Selling Stockholder and the Underwriters agree that
it would not be just and equitable if contributions pursuant to this subsection
(e) were determined by pro rata allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to above
in this subsection (e). The amount paid or payable by an indemnified party as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above in this subsection (e) shall be deemed to include
any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (e), no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Shares underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
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 Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this subsection (e) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

         (f) The obligations of the Company and the Selling Stockholder under
this Section 9 shall be in addition to any liability which the Company and the
Selling Stockholder may otherwise have and shall extend, upon the same terms
and conditions, to each person, if any, who controls any Underwriter within the
meaning of the Act; and the obligations of the Underwriters under this Section
9 shall be in addition to any liability which the respective Underwriters may
otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company (including any person who, with his or her
consent, is named in the Registration Statement as about to become a director
of the Company) and to each person, if any, who controls the Company or the
Selling Stockholder within the meaning of the Act.

         (g) The Company shall indemnify and hold harmless Lehman Brothers Inc.
(including its directors, officers and employees) and each person, if any, who
controls Lehman Brothers Inc. within the meaning of Section 15 of the
Securities Act ("Lehman Brothers Entities"), from and against any loss, claim,
damage or liability or any action in respect thereof to which any of the Lehman
Brothers Entities may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action (i) arises out of, or
is based upon, any untrue statement or alleged untrue statement of a material
fact contained in any material prepared by or with the approval of the Company
for distribution to Directed Share participants in connection with the Directed
Share Program or any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, (ii) arises out of, or is based upon, the failure of the
Directed Share Participant to pay for and accept delivery of Directed Shares
that the Directed Share Participant agreed to purchase or (iii) is otherwise
related to the Directed Share Program; provided that, the Company shall not be
liable under this clause (iii) for any loss, claim, damage, liability or action
that is determined in a final judgment by a court of competent jurisdiction to
have resulted from the gross negligence or willful misconduct of the Lehman
Brothers Entities. The Company shall reimburse the Lehman Brothers Entities
promptly upon demand for any legal or other expenses reasonably incurred by
them in connection with investigating or defending or preparing to defend
against any such loss, claim, damage, liability or action as such expenses are
incurred.

         10. (a) If any Underwriter shall default in its obligation to purchase
the Shares which it has agreed to purchase hereunder at a Time of Delivery, you
may in your discretion arrange for you or another party or other parties to
purchase such Shares on the terms contained herein. If within thirty-six hours
after such default by any Underwriter you do not arrange for the purchase of
such Shares, then the Company and the Selling Stockholder shall be entitled to
a further period of thirty-six hours within which to procure another party or
other parties satisfactory to you to purchase such Shares on such terms. In the
event that, within the respective prescribed periods, you notify the Company
and the Selling Stockholder that you have so arranged for the purchase of such
Shares, or the Company and the Selling Stockholder notify you that they have so
arranged for the purchase of such Shares, you or the Company and the Selling
Stockholder shall have the right to postpone a Time of Delivery for a period of
not more than seven days, in order to effect whatever changes may thereby be
made necessary in the Registration Statement or the Prospectus, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments or supplements to the Registration Statement or the Prospectus which
in your opinion may thereby be made necessary. The term "Underwriter" as used
in this Agreement shall include any person substituted under this Section 10
with like effect as if such person had originally been a party to this
Agreement with respect to such Shares.

         (b) If, after giving effect to any arrangements for the purchase of
the Shares of a defaulting Underwriter or Underwriters by you and the Company
and the Selling Stockholder as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased does not exceed one-eleventh of
the aggregate number of all the Shares to be purchased at such Time of
Delivery, then the Company and the Selling Stockholder shall have the right to
require each non-defaulting Underwriter to purchase the number of Shares which
such Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

         (c) If, after giving effect to any arrangements for the purchase of
the Shares of a defaulting Underwriter or Underwriters by you and the Company
and the Selling Stockholder as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased exceeds one-eleventh of the
aggregate number of all of the Shares to be purchased at such Time of Delivery,
or if the Company and the Selling Stockholder shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Shares of a defaulting Underwriter or Underwriters, then this
Agreement (or, with respect to the Second Time of Delivery, the obligations of
the Underwriters to purchase and of the Company to sell the Optional Shares)
shall thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company or the Selling Stockholder, except for the expenses
to be borne by the Company and the Selling Stockholder and the Underwriters as
provided in Section 7 hereof and the indemnity and contribution agreements in
Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter
from liability for its default.

         11. The respective indemnities, agreements, representations,
warranties and other statements of the Company, the Selling Stockholder and the
several Underwriters, as set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement, shall remain in full force and
effect, regardless of any investigation (or any statement as to the results
thereof) made by or on behalf of any Underwriter or any controlling person of
any Underwriter, or the Company, or any of the Selling Stockholder, or any
officer or director or controlling person of the Company, or any controlling
person of the Selling Stockholder, and shall survive delivery of and payment
for the Shares.

         12. If this Agreement shall be terminated pursuant to Section 10
hereof, neither the Company nor the Selling Stockholder shall then be under any
liability to any Underwriter except as provided in Sections 7 and 9 hereof; but
if for any other reason any Shares are not delivered by or on behalf of the
Company or the Selling Stockholder as provided herein, the Company and the
Selling Stockholder pro rata (based on the number of Shares to be sold by the
Company and the Selling Stockholder hereunder) will reimburse the Underwriters
through you for all out-of-pocket expenses approved in writing by you,
including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of the
Shares not so delivered, but the Company and the Selling Stockholder shall then
be under no further liability to any Underwriter in respect of the Shares not
so delivered except as provided in Sections 7 and 9 hereof.

         13. (a) In all dealings hereunder, you shall act on behalf of each of
the Underwriters, and the parties hereto shall be entitled to act and rely upon
any statement, request, notice or agreement on behalf of any Underwriter made
or given by you jointly or by Goldman, Sachs & Co. or Lehman Brothers Inc. on
behalf of you as the representatives; and in all dealings with any Selling
Stockholder hereunder, you and the Company shall be entitled to act and rely
upon any statement, request, notice or agreement on behalf of the Selling
Stockholder made or given by any or all of the Attorneys-in-Fact for the
Selling Stockholder.

         (b) All statements, requests, notices and agreements hereunder shall be
in writing, and if to the Underwriters shall be delivered or sent by mail, telex
or facsimile transmission to you as the representatives in care of Goldman,
Sachs & Co., One New York Plaza, 42nd Floor, New York, New York 10004,
Attention: Registration Department and Lehman Brothers Inc., 745 Seventh Avenue,
New York, New York 10019, Attention: Syndicate Registration (Fax: 646-834-8133),
with a copy, in the case of any notice pursuant to Section 9, to the Director of
Litigation, Office of the General Counsel, Lehman Brothers Inc., 399 Park
Avenue, 10th Floor, New York, New York 10022 (Fax: 212-520-0421); if to the
Selling Stockholder shall be delivered or sent by mail, telex or facsimile
transmission to counsel for the Selling Stockholder at c/o Capital Z Management,
LLC, 230 Park Avenue South, New York, New York 10003; and if to the Company
shall be delivered or sent by mail, telex or facsimile transmission to the
address of the Company set forth in the Registration Statement, Attention:
Secretary; provided, however, that any notice to an Underwriter pursuant to
Section 9(c) hereof shall be delivered or sent by mail, telex or facsimile
transmission to such Underwriter at its address set forth in its Underwriters'
Questionnaire or telex constituting such Questionnaire, which address will be
supplied to the Company or the Selling Stockholder by you on request; provided,
however, that notices under subsection 5(e) shall be in writing, and if to the
Underwriters shall be delivered or sent by mail, telex or facsimile transmission
to you as the representatives at Goldman, Sachs & Co., 85 Broad Street, New
York, New York 10004, Attention: Control Room and Lehman Brothers Inc., 399 Park
Avenue, 8th Floor, New York, New York 10022, Attention: Syndicate Department.
Any such statements, requests, notices or agreements shall take effect upon
receipt thereof.

         14. This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Company and the Selling Stockholder and, to
the extent provided in Sections 9 and 11 hereof, the officers and directors of
the Company and each person who controls the Company, the Selling Stockholder
or any Underwriter, and their respective heirs, executors, administrators,
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement. No purchaser of any of the Shares from
any Underwriter shall be deemed a successor or assign by reason merely of such
purchase.

         15. Each of the Company and the Selling Stockholder acknowledges and
agrees that (i) the purchase and sale of the Shares pursuant to this Agreement
is an arm's-length commercial transaction between the Company or the Selling
Stockholder, as applicable, on the one hand, and the several Underwriters, on
the other, (ii) in connection therewith and with the process leading to such
transaction each Underwriter is acting solely as a principal and not the agent
or fiduciary of the Company or the Selling Stockholder, (iii) no Underwriter
has assumed an advisory or fiduciary responsibility in favor of the Company or
the Selling Stockholder with respect to the offering contemplated hereby or the
process leading thereto (irrespective of whether such Underwriter has advised
or is currently advising the Company or the Selling Stockholder on other
matters) or any other obligation to the Company or the Selling Stockholder
except the obligations expressly set forth in this Agreement and (iv) the
Company or the Selling Stockholder has consulted its own legal and financial
advisors to the extent it deemed appropriate. The Company and the Selling
Stockholder agrees that it will not claim that the Underwriters, or any of
them, has rendered advisory services of any nature or respect, or owes a
fiduciary or similar duty to the Company or the Selling Stockholder, in
connection with such transaction or the process leading thereto.

         16. Time shall be of the essence of this Agreement. As used herein,
the term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

         17. This Agreement shall be governed by and construed in accordance
with the laws of the State of New York.

         18. This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

         19. Notwithstanding anything herein to the contrary, the Company and
the Selling Stockholder are authorized to disclose to any persons the U.S.
federal and state income tax treatment and tax structure of the potential
transaction and all materials of any kind (including tax opinions and other tax
analyses) provided to the Company and the Selling Stockholder relating to that
treatment and structure, without the Underwriters imposing any limitation of
any kind. However, any information relating to the tax treatment and tax
structure shall remain confidential (and the foregoing sentence shall not
apply) to the extent necessary to enable any person to comply with securities
laws. For this purpose, "tax structure" is limited to any facts that may be
relevant to that treatment.

         If the foregoing is in accordance with your understanding, please sign
and return to us one for the Company and each of the Representatives plus one
for each counsel and the Custodian, if any counterparts hereof, and upon the
acceptance hereof by you, on behalf of each of the Underwriters, this letter
and such acceptance hereof shall constitute a binding agreement among each of
the Underwriters, the Company and the Selling Stockholder. It is understood
that your acceptance of this letter on behalf of each of the Underwriters is
pursuant to the authority set forth in a form of Agreement among Underwriters,
the form of which shall be submitted to the Company and the Selling Stockholder
for examination, upon request, but without warranty on your part as to the
authority of the signers thereof.

         Any person executing and delivering this Agreement as Attorney-in-Fact
for a Selling Stockholder represents by so doing that he has been duly
appointed as Attorney-in-Fact by the Selling Stockholder pursuant to a validly
existing and binding Power of Attorney which authorizes such Attorney-in-Fact
to take such action.




                                       Very truly yours,
