               New York, N.Y. 10010-3629

Dear Sirs:


         1. INTRODUCTORY. United Surgical Partners Holdings, Inc., a Delaware
corporation (the "COMPANY") and wholly-owned subsidiary of United Surgical
Partners International, Inc., a Delaware corporation (the "PARENT"), proposes to
issue and sell to the several initial purchasers named on SCHEDULE A hereto (the
"PURCHASERS") upon the terms and subject to the conditions set forth in this
agreement (the "PURCHASE AGREEMENT") U.S. $150,000,000 principal amount of its
10% Senior Subordinated Notes due 2011 (the "NOTES") to be issued under an
indenture, dated as of December 19, 2001 (the "INDENTURE"), among the Company,
the guarantors from time to time parties thereto (the "GUARANTORS") and U.S.
Trust Company of Texas, N.A. as trustee (the "TRUSTEE"). The Notes will be
guaranteed (the "GUARANTEE," and together with the Notes, the "OFFERED
SECURITIES") by the Guarantors. The United States Securities Act of 1933 is
herein referred to as the "SECURITIES ACT."

         Holders (including subsequent transferees) of the Offered Securities
will have the registration rights set forth in the registration rights agreement
(the "REGISTRATION RIGHTS AGREEMENT"), to be dated the Closing Date (as
hereinafter defined), in substantially the form of EXHIBIT I hereto, for so long
as such Offered Securities constitute "TRANSFER RESTRICTED SECURITIES" (as
defined in the Registration Rights Agreement). Pursuant to the Registration
Rights Agreement, the Company and the Guarantors will agree to file with the
Securities and Exchange Commission (the "COMMISSION") under the circumstances
and upon the terms and subject to the conditions set forth therein, (i) a
registration statement under the Securities Act (the "EXCHANGE OFFER
REGISTRATION STATEMENT") relating to the Company's 10% Senior Subordinated Notes
in a like aggregate principal amount as the Company issued under the Indenture,
identical in all material respects to the Offered Securities and registered
under the Securities Act (the "EXCHANGE SECURITIES"), to be offered in exchange
for the Offered Securities (such offer to exchange being referred to as the
"EXCHANGE OFFER") and, if applicable, (ii) a shelf registration statement
pursuant to Rule 415 under the Securities Act (the "SHELF REGISTRATION
STATEMENT" and, together with the Exchange Offer Registration Statement, the
"REGISTRATION STATEMENTS") relating to the resale by certain holders of the
Offered Securities and to use their reasonable best efforts to cause such
Registration Statements to be declared and remain effective and usable for the
periods specified in the Registration Rights Agreement and to consummate the
Exchange Offer. The Offered Securities and the Exchange Securities are referred
to collectively as the "SECURITIES."

         The Company and the Guarantors hereby agree with the several Purchasers
as follows:

<Page>

         2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE GUARANTORS.
The Company and the Guarantors represent and warrant to, and agree with, the
several Purchasers that:

                  (a) A preliminary offering circular and an offering circular
         relating to the Offered Securities to be offered by the Purchasers have
         been prepared by the Company. Such preliminary offering circular (the
         "PRELIMINARY OFFERING CIRCULAR") and offering circular (the "OFFERING
         CIRCULAR"), as supplemented as of the date of this Agreement and any
         other document approved by the Company for use in connection with the
         contemplated resale of the Offered Securities are hereinafter
         collectively referred to as the "OFFERING DOCUMENT." On the date of
         this Agreement, the Offering Document does 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. The preceding
         sentence does not apply to statements in or omissions from the Offering
         Document based upon written information furnished to the Company by any
         Purchaser through Credit Suisse First Boston Corporation ("CSFBC")
         specifically for use therein, it being understood and agreed that the
         only such information is that described as such in Section 7(b) hereof.
         Except as disclosed in the Offering Document, on the date of this
         Purchase Agreement, the Company's Quarterly Report on Form 10-Q filed
         with the Commission on August 14, 2001 and all subsequent reports
         (collectively, the "EXCHANGE ACT REPORTS") which have been filed by the
         Company with the Commission or sent to stockholders pursuant to the
         Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), do
         not include any untrue statement of a material fact or omit to state
         any material fact necessary to make the statements therein, in the
         light of the circumstances under which they were made, not misleading.
         Such documents, when they were filed with the Commission, conformed in
         all material respects to the requirements of the Exchange Act and the
         rules and regulations of the Commission thereunder.

                  (b) The Company and the Parent have each been duly
         incorporated and each is an existing corporation in good standing under
         the laws of the State of Delaware, with power and authority (corporate
         and other) to own their respective properties and conduct their
         respective business as described in the Offering Document; and the
         Company and the Parent each are duly qualified to do business as a
         foreign corporation in good standing in all other jurisdictions in
         which their respective ownership or lease of property or the conduct of
         their respective business requires such qualification, except where the
         failure to be so qualified or to be in good standing would not,
         individually or in the aggregate, have a material adverse effect on the
         business, condition (financial or otherwise), properties or results of
         operations of the Company, the Parent and the Company's subsidiaries
         taken as a whole ("MATERIAL ADVERSE EFFECT"). SCHEDULE B attached
         hereto is a true, complete and correct list of all of the direct and
         indirect subsidiaries of the Parent and indicating their respective
         jurisdictions of formation or organization, the Parent's direct or
         indirect ownership therein, and whether such entity is a Guarantor
         (each such subsidiary, including the Company, a "PARENT SUBSIDIARY,"
         and collectively, the "PARENT SUBSIDIARIES").

                  (c) Each Parent Subsidiary has been duly incorporated or
         organized and is an existing corporation, limited partnership or
         limited liability company in good standing under the laws of the
         jurisdiction of its incorporation or organization, with power and
         authority (corporate and other) to own its properties and conduct its
         business as described in the Offering Document; and each Parent
         Subsidiary is duly qualified to do business as a foreign corporation,
         limited partnership or limited liability company in good standing in
         all other jurisdictions in which its ownership or lease of property or
         the conduct of its business requires such qualification, except where
         the failure to be so qualified or to be in good standing would not,
         individually or in the aggregate, have a Material Adverse Effect; all
         of the issued and outstanding capital stock or similar ownership
         interest of each Parent Subsidiary has been duly authorized and validly
         issued and is fully paid and nonassessable; and the capital stock or
         similar ownership interest of each Parent Subsidiary owned by the
         Parent, directly or through subsidiaries, is owned free from liens,
         encumbrances and defects other than

                                       2

<Page>

         those liens permitted pursuant to the existing domestic credit
         facility as defined in the Offering Circular ("PERMITTED LIENS"),
         except where such lien, encumbrance and/or defect would not have a
         Material Adverse Effect.

                  (d) The Indenture has been duly authorized; the Offered
         Securities have been duly authorized; and when the Offered Securities
         are delivered and paid for pursuant to this Purchase Agreement on the
         Closing Date (as defined below), the Indenture will have been duly
         executed and delivered by the Company and the Guarantors, such Offered
         Securities will have been duly executed, authenticated, issued and
         delivered and will conform to the description thereof contained in the
         Offering Document and the Indenture and such Offered Securities will
         constitute valid and legally binding obligations of the Company and the
         Guarantors, enforceable against the Company and the Guarantors in
         accordance with their terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equitable principles (regardless of whether considered in a
         proceeding in equity or law).

                  (e) Except as disclosed in the Offering Document, there are no
         contracts, agreements or understandings between the Company or any
         Guarantor on the one hand, and any person on the other hand that would
         give rise to a valid claim against the Company, any Guarantor or any
         Purchaser for a brokerage commission, finder's fee or other like
         payment in connection with this offering.

                  (f ) No consent, approval, authorization, or order of, or
         filing with, any governmental agency or body or any court or any
         securities industry self-regulatory organization is required for the
         consummation of the transactions contemplated by this Purchase
         Agreement and the Registration Rights Agreement in connection with the
         issuance and sale of the Offered Securities by the Company and the
         Guarantors, except such as have been obtained or made under the
         Securities Act and except for filing of the Registration Statements
         with the Commission and the order of the Commission declaring them
         effective or as may be required by state securities laws.

                  (g) The execution, delivery and performance of this Purchase
         Agreement, the Registration Rights Agreement and the Indenture by the
         Company and the Guarantors, and the issuance and sale of the Offered
         Securities by the Company and the Guarantors will not: (i) result in a
         breach or violation of any of the terms and provisions of, or
         constitute a default under, (a) any statute, rule, regulation or order
         of any governmental agency or body or any court, domestic or foreign,
         having jurisdiction over the Company, the Parent or any Parent
         Subsidiary or any of their properties, assuming compliance with state
         securities laws, (b) any agreement or instrument, other than the
         existing domestic credit facility as defined in the Offering Circular
         which we expect to amend prior to or concurrently with the offering, to
         which the Company, the Parent or any such Parent Subsidiary is a party
         or by which the Company, the Parent or any such Parent Subsidiary is
         bound or to which any of the properties of the Company, the Parent or
         any such Parent Subsidiary is subject, or (c) the charter or by-laws of
         the Company or the Parent or the charter, by-laws or other
         organizational documents of any such Parent Subsidiary; or (ii) result
         in the creation or imposition of any lien, charge, claim or encumbrance
         upon any property or asset of the Company, the Parent or any such
         Parent Subsidiary, other than, in the case of breaches, violations or
         defaults described in clauses (i)(b) and liens, charges, claims or
         encumbrances described in clause (ii) that would not, individually or
         in the aggregate, have a Material Adverse Effect; and the Company and
         the Guarantors have full power and authority to authorize, issue and
         sell the Offered Securities as contemplated by this Agreement.

                  (h) This Purchase Agreement has been duly authorized, executed
         and delivered by the Company and the Guarantors.

                                       3

                  (i) Except as disclosed in the Offering Document, the Company,
         the Parent and the Parent Subsidiaries have good and marketable title
         to all real properties and all other properties and assets owned by
         them, in each case free from liens, encumbrances and defects that would
         materially affect the value thereof or materially interfere with the
         use made or to be made thereof by them; and except as disclosed in the
         Offering Document, the Company, the Parent and the Parent Subsidiaries
         hold any leased real or personal property under valid and enforceable
         leases with no exceptions that would materially interfere with the use
         made or to be made thereof by them, in each case, other than Permitted
         Liens.

                  (j) The Company, the Parent and the Parent Subsidiaries
         possess such certificates, consents, exemptions, orders, licenses,
         authorities, accreditations or permits issued by appropriate
         governmental agencies, self-regulatory organizations, governmental and
         private accrediting bodies and courts and other tribunals
         (collectively, the "PERMITS") necessary to conduct the business now
         owned, operated or managed by them, including but not limited to such
         Permits as are required with respect to those facilities owned,
         operated or managed by the Parent or any of the Parent Subsidiaries
         that participate in Medicare and/or Medicaid, to receive reimbursement
         thereunder, except for such failures to have Permits which would not,
         individually or in the aggregate, have a Material Adverse Effect. The
         Company, the Parent and the Parent Subsidiaries have not received any
         notice of proceedings relating to the revocation or modification of any
         such Permit that, if determined adversely to the Company, the Parent or
         any of the Parent Subsidiaries, would, individually or in the
         aggregate, result in a Material Adverse Effect. The Company, the Parent
         and the Parent Subsidiaries have fulfilled and performed all of their
         material obligations with respect to such Permits, and no event or
         change in condition has occurred which allows, or after notice or lapse
         of time or both would allow, revocation or termination thereof or
         result in any other material impairment of the rights of the holder of
         any such Permit, except as to such qualifications as are set forth in
         the Offering Documents and except for such failures which would not,
         individually or in the aggregate, result in a Material Adverse Effect.
         During the period for which financial statements are included in the
         Offering Documents, denials by third party payors of claims for
         reimbursement for services rendered by the Company, the Parent and the
         Parent Subsidiaries have not had a Material Adverse Effect.

                  (k) The accounts receivable of the Company, the Parent and the
         Parent Subsidiaries are recorded based on established billing rates
         less estimates for contractual allowances to reflect reimbursement
         arrangements with third party payors such as Medicare, Medicaid, Blue
         Cross/Blue Shield, private insurance companies, health maintenance
         organizations, preferred provider organizations, managed care systems
         and other third party payors. The accounts receivable relating to such
         third party payors do not and shall not exceed amounts the Parent and
         the Parent Subsidiaries are entitled to receive, subject to adjustments
         to reflect reimbursement arrangements with third party payors and
         normal discounts in the ordinary course. Additionally, accounts
         receivable of the Parent and the Parent Subsidiaries are net of
         estimated allowances for doubtful accounts.

                  (l) None of the Company, the Parent or any of the Parent
         Subsidiaries, nor any of their respective officers, directors or
         stockholders, or to the knowledge of the Company or the Parent, any
         employee or other agent of the Company, the Parent or the Parent
         Subsidiaries, has engaged on behalf of the Company, the Parent or any
         of the Parent Subsidiaries in any of the following: (i) knowingly and
         willfully making or causing to be made a false statement or
         representation of a material fact in any applications for any benefit
         or payment under the Medicare or Medicaid program or from any third
         party (where applicable Federal or state law prohibits such payments to
         third parties); (ii) knowingly and willfully making or causing to be
         made any false statement or representation of a material fact for use
         in determining rights to any benefit or payment under the Medicare or
         Medicaid program or from any third party (where applicable Federal or
         state law prohibits such payments to third parties); (iii) failing to
         disclose knowledge by a claimant of the occurrence of any event
         affecting the initial or continued right to any benefit or payment
         under the

                                       4

<Page>

         Medicare or Medicaid program or from any third party (where applicable
         Federal or state law prohibits such payments to third parties) on its
         own behalf or on behalf of another, with intent to secure such benefit
         or payment fraudulently; (iv) knowingly and willfully offering,
         paying, soliciting or receiving any remuneration (including any
         kickback, bribe or rebate), directly or indirectly, overtly or
         covertly, in cash or in kind (a) in return for referring an individual
         to a Person for the furnishing or arranging for the furnishing of any
         item or service for which payment may be made in whole or in part by
         Medicare or Medicaid or any third party (where applicable Federal or
         state law prohibits such payments to third parties), or (b) in return
         for purchasing, leasing or ordering or arranging for or recommending
         the purchasing, leasing or ordering of any good, facility, service, or
         item for which payment may be made in whole or in part by Medicare or
         Medicaid or any third party (where applicable Federal or state law
         prohibits such payments to third parties).

                  (m) No labor dispute with the employees of the Company, the
         Parent or any Parent Subsidiary exists or, to the knowledge of the
         Company or the Parent, is imminent that is reasonably likely to have a
         Material Adverse Effect.

                  (n) The Company, the Parent and the Parent Subsidiaries own or
         possess licenses or other enforceable legal rights to use or can
         acquire on reasonable terms, adequate trademarks, trade names and other
         rights to inventions, know-how, patents, copyrights, confidential
         information and other intellectual property (collectively,
         "INTELLECTUAL PROPERTY RIGHTS") necessary to conduct the business now
         operated by them, or presently employed by them, and have not received
         any notice of infringement of or conflict with asserted rights of
         others with respect to any intellectual property rights that, if
         determined adversely to the Company, the Parent or any of the Parent
         Subsidiaries would, individually or in the aggregate, have a Material
         Adverse Effect.

                  (o) Except as disclosed in the Offering Document, neither the
         Company, the Parent nor any of the Parent Subsidiaries is in violation
         of any statute, rule, regulation, decision or order of any governmental
         agency or body or any court, domestic or foreign, relating to the use,
         disposal or release of hazardous or toxic substances or relating to the
         protection or restoration of the environment or human exposure to
         hazardous or toxic substances (collectively, "ENVIRONMENTAL LAWS"),
         owns or operates any real property contaminated with any substance that
         is subject to any environmental laws, is liable for any off-site
         disposal or contamination pursuant to any environmental laws, or is
         subject to any claim relating to any environmental laws, which
         violation, contamination, liability or claim would individually or in
         the aggregate have a Material Adverse Effect; and neither the Company
         nor the Parent is aware of any pending investigation which might lead
         to such a claim.

                  (p) Except as disclosed in the Offering Document, there are no
         pending actions, suits or proceedings against or affecting the Company,
         the Parent, any of the Parent Subsidiaries or any of their respective
         properties that, if determined adversely to the Company, the Parent or
         any of the Parent Subsidiaries would, individually or in the aggregate,
         have a Material Adverse Effect, or would materially and adversely
         affect the ability of the Company or the Guarantors to perform their
         respective obligations under the Indenture, this Purchase Agreement or
         the Registration Rights Agreement, or which are otherwise material in
         the context of the sale of the Offered Securities; and no such actions,
         suits or proceedings are, to the Company's or the Parent's knowledge,
         threatened or contemplated.

                  (q) The financial statements included in the Offering Document
         present fairly, in all material respects, the financial position of the
         Parent and its consolidated subsidiaries as of the dates shown and
         their results of operations and cash flows for the periods shown, and,
         except as otherwise disclosed in the Offering Document, 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 assumptions used in preparing the pro forma financial
         statements included

                                       5

<Page>

         in the Offering Document provide a reasonable basis for presenting the
         significant effects directly attributable to the transactions or
         events described therein, the related pro forma adjustments give
         appropriate effect to those assumptions, and the pro forma columns
         therein reflect the proper application of those adjustments to the
         corresponding historical financial statement amounts.

                  (r) Except as disclosed in the Offering Document, since the
         date of the latest audited financial statements included in the
         Offering Document there has been no material adverse change, nor any
         development or event involving a prospective material adverse change,
         in the condition (financial or other), business, properties or results
         of operations of the Parent, the Company and the Parent Subsidiaries
         taken as a whole, and there has been no dividend or distribution of any
         kind declared, paid or made by the Parent or the Company on any class
         of its capital stock.

                  (s) Neither the Company nor any Guarantor is an open-end
         investment company, unit investment trust or face-amount certificate
         company that is or is required to be registered under Section 8 of the
         United States Investment Company Act of 1940 (the "INVESTMENT COMPANY
         ACT"); and neither the Company nor any Guarantor is, and after giving
         effect to the offering and sale of the Offered Securities and the
         application of the proceeds thereof as described in the Offering
         Document, neither will be, an "investment company" as defined in the
         Investment Company Act.

                  (t) No securities of the same class (within the meaning of
         Rule 144A(d)(3) under the Securities Act) as the Offered Securities are
         listed on any national securities exchange registered under Section 6
         of the Exchange Act or quoted in a U.S. automated inter-dealer
         quotation system.

                  (u) Assuming the accuracy of the representations and
         warranties of the Purchasers as set forth in Section 4 hereof, and the

         the Company or such Guarantor or to require the Company or such
         Guarantor to include such securities with the Offered Securities
         registered pursuant to any Registration Statement.

         (as defined in Regulation D under the Securities Act) was used by the
         Company, the Guarantors or any of their respective representatives

         amend or supplement the Offering Document and will not effect such
         amendment or supplementation without CSFBC's consent. If, at any time
         prior to the completion of the resale of the Offered Securities by the
         Purchasers, any event occurs as a result of which the Offering Document
         as then amended or supplemented would include an 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, or if it is necessary at such
         time to amend or supplement the Offering Document to comply with any
         applicable law, the Company will promptly notify CSFBC of such event
         and will promptly prepare, at its own expense, an amendment or
         supplement which will correct such statement or omission or to effect
         such compliance. Neither CSFBC's consent to, nor the Purchasers'
         delivery to offerees or investors of, any such amendment or supplement
         shall constitute a waiver of any of the conditions set forth in Section
         6.

                  (b) The Company will furnish to CSFBC copies of any Offering
         Document and all amendments and supplements to such documents, in each
         case as soon as available and in such quantities as CSFBC requests, and
         the Company will furnish to CSFBC on the date hereof three copies of
         the Offering Document, one of which will include the independent

         accountants. At any time when the Company is not subject to Section 13
         or 15(d) of the Exchange Act, the Company will promptly furnish or
         cause to be furnished to CSFBC (and, upon request, to each of the other
         Purchasers) and, upon request of holders and prospective purchasers of
         the Offered Securities, to such holders and purchasers, copies of the
         information required to be delivered to holders and prospective
         purchasers of the Offered Securities pursuant to Rule 144A(d)(4) under
         the Securities Act (or any successor provision thereto) in order to
         permit compliance with Rule 144A in connection with resales by such
         holders of the Offered Securities. The Company will pay the expenses of
         printing and distributing to the Purchasers all such documents.

                  (c) The Company will arrange for the qualification of the
         Offered Securities for sale and the determination of their eligibility
         for investment under the laws of such jurisdictions in the United
         States and Canada as CSFBC designates and will continue such
         qualifications in effect so long as required for the resale of the
         Offered Securities by the Purchasers, provided that the Company will
         not be required to qualify as a foreign corporation or to file a
         general consent to service of process in any such jurisdiction.

                  (d) During the period of five years hereafter, the Company
         will furnish to CSFBC and, upon request, to each of the other
         Purchasers, as soon as practicable after the end of each fiscal year, a
         copy of its annual report to stockholders for such year; and the
         Company will furnish to CSFBC and, upon request, to each of the other
         Purchasers (i) as soon as available, a copy of each report and any
         definitive proxy statement of the Company filed with the Commission
         under the Exchange Act or mailed to stockholders, and (ii) from time to
         time, such other information concerning the Company as CSFBC may
         reasonably request, which such other information shall be kept
         confidential by the Purchasers to the extent requested by the Company
         in writing at the time of delivery of such information; provided that
         CSFBC and such other Purchasers shall have no such obligation with
         respect to any such information which (i) prior to delivery to the
         Purchasers was already in their possession, (ii) is or becomes
         otherwise publicly available, without breach of this provision, (iii)
         becomes available to the Purchasers on a non-confidential basis from a
         source other than the Company, provided that, after reasonable inquiry,
         the Purchasers do not know that such source is bound by a
         confidentiality agreement with, or obligation of secrecy to, the
         Company or (iv) the Purchasers are legally compelled to disclose such
         information.

         Securities that have been reacquired by any of them.

                  (g) During the period of two years after the Closing Date,
         neither the Company nor any Guarantor will be or become, an open-end
         investment company, unit investment trust or face-amount certificate
         company that is or is required to be registered under Section 8 of the
         Investment Company Act.

                  (h) The Company will pay all expenses incidental to the
         performance of its obligations under this Purchase Agreement, the
         Indenture, and the Registration Rights Agreement, including (i) the
         fees and expenses of the Trustee and its professional advisers; (ii)

         the issue of the Offered Securities; (v) for any expenses (including
         fees and disbursements of counsel) incurred in connection with
         qualification of the Offered Securities or the Exchange Securities for
         sale under the laws of such jurisdictions in the United States and
         Canada as CSFBC designates and the printing of memoranda relating

                  (i) In connection with the offering, until CSFBC shall have
         notified the Company and the other Purchasers of the completion of the
         resale of the Offered Securities, neither the Company nor any of its
         affiliates has or will, either alone or with one or more other persons,
         bid for or purchase for any account in which it or any of its
         affiliates has a beneficial interest any Offered Securities or attempt
         to induce any person to purchase any Offered Securities; and neither it
         nor any of its affiliates will make bids or purchases for the purpose
         of creating actual, or apparent, active trading in, or of raising the
         price of, the Offered Securities.

                  (j) For a period of 180 days after the date of the initial
         offering of the Offered Securities by the Purchasers, the Company will
         not offer, sell, contract to sell, pledge or otherwise dispose of,
         directly or indirectly, any United States dollar-denominated debt
         securities or Euro-denominated debt securities issued or guaranteed by
         the Company and having a maturity of more than one year from the date
         of issue. The Company will not at any time offer, sell, contract to
         sell, pledge or otherwise dispose of, directly or indirectly, any
         securities under circumstances where such offer, sale, pledge, contract
         or disposition would cause the exemption afforded by Section 4(2) of
         the Securities Act or the safe harbor of Regulation S thereunder to
         cease to be applicable to the offer and sale of the Offered Securities.

Company herein, to the accuracy of the statements of officers of the Company

the Guarantors of their respective obligations hereunder and to the following

                  (a) The Purchasers shall have received a letter, dated the
         date of this Purchase Agreement, of KPMG LLP confirming that they are
         independent public accountants within the meaning of the Securities Act
         and the applicable published rules and regulations thereunder ("RULES
         AND REGULATIONS") and to the effect that:

                           (i) in their opinion the financial statements
                  examined by them and included in the Offering Document comply
                  as to form in all material respects with the applicable
                  accounting requirements of the Securities Act and the related
                  published Rules and Regulations;

                           (ii) they have performed the procedures specified by
                  the American Institute of Certified Public Accountants for a
                  review of interim financial information as described in
                  Statement of Auditing Standards No. 71, Interim Financial
                  Information, on the unaudited financial statements included in
                  the Offering Document;

                           (iii) on the basis of the review referred to in
                  clause (ii) above, a reading of the latest available interim
                  financial statements of the Parent, inquiries of officials of
                  the Parent who have responsibility for financial and
                  accounting matters and other specified procedures, nothing
                  came to their attention that caused them to believe that:

                                    (A) the unaudited financial statements
                           included in the Offering Document do not comply as to
                           form in all material respects with the applicable
                           accounting requirements of the Securities Act and the
                           related published Rules and Regulations or any
                           material modifications should be made to such
                           unaudited financial statements for them to be in
                           conformity with generally accepted accounting
                           principles;

                                    (B) the unaudited consolidated total
                           revenues, net operating income, net income and net
                           income per share amounts for the nine-month periods
                           ended September 30, 2000 and September 30, 2001

                           the amounts set forth in the unaudited consolidated
                           financial statements for those same periods or were
                           not determined on a basis substantially consistent
                           with that of the corresponding amounts in the audited
                           statements of income;

                                    (C) at the date of the latest available
                           balance sheet read by such accountants, or at a
                           subsequent specified date not more than three
                           business days prior to the date of this Agreement,
                           there was any increase in consolidated net current
                           liabilities or any change in the capital stock or any
                           increase in short-term indebtedness or long-term debt
                           of the Parent and its consolidated subsidiaries or,
                           at the date of the latest available balance sheet
                           read by such accountants, there was any decrease in
                           consolidated net current assets or net assets, as
                           compared with amounts shown on the latest balance
                           sheet included in the Offering Document; or

                                    (D) for the period from the closing date of
                           the latest income statement included in the Offering
                           Document to the closing date of the latest available
                           income statement read by such accountants there were
                           any decreases, as

                                       12

<Page>

                           compared with the corresponding period of the
                           previous year, in consolidated total revenues,
                           operating income or consolidated net income;

                  except in all cases set forth in clauses (C) and (D) above for
                  changes, increases or decreases which the Offering Document
                  disclosed have occurred or may occur or which are described in
                  such letter; and

                           (iv) they have compared specified dollar amounts (or
                  percentages derived from such dollar amounts) and other
                  financial information contained in the Offering Document (in
                  each case to the extent that such dollar amounts, percentages
                  and other financial information are derived from the general
                  accounting records of the Parent and the Parent Subsidiaries
                  subject to the internal controls of the Parent's accounting
                  system or are derived directly from such records by analysis
                  or computation) with the results obtained from inquiries, a
                  reading of such general accounting records and other
                  procedures specified in such letter and have found such dollar
                  amounts, percentages and other financial information to be in
                  agreement with such results, except as otherwise specified in
                  such letter.

                  (b) Subsequent to the execution and delivery of this Purchase
         Agreement, there shall not have occurred (i) a change in U.S. or
         international financial, political or economic conditions or currency
         exchange rates or exchange controls as would, in the judgment of CSFBC,
         be likely to prejudice materially the success of the proposed issue,
         sale or distribution of the Offered Securities, whether in the primary
         market or in respect of dealings in the secondary market, or (ii) (A)
         any change, or any development or event involving a prospective change,
         in the condition (financial or other), business, properties or results
         of operations of the Company and the Parent Subsidiaries taken as one
         enterprise which, in the judgment of a majority in interest of the
         Purchasers, including CSFBC, is material and adverse and makes it
         impractical or inadvisable to proceed with completion of the offering
         or the sale of and payment for the Offered Securities; (B) any
         downgrading in the rating of any debt securities of the Company by any
         "nationally recognized statistical rating organization" (as defined for
         purposes of Rule 436(g) under the Securities Act), or any public
         announcement that any such organization has under surveillance or
         review its rating of any debt securities of the Company (other than an
         announcement with positive implications of a possible upgrading, and no
         implication of a possible downgrading, of such rating); (C) any
         material suspension or material limitation of trading in securities
         generally on the New York Stock Exchange or any setting of minimum
         prices for trading on such exchange, or any suspension of trading of
         any securities of the Company on any exchange or in the
         over-the-counter market; (D) any banking moratorium declared by U.S.
         Federal or New York authorities; (E) any major disruption of
         settlements of securities; or (F) any attack on, outbreak or escalation
         of major hostilities or major act of terrorism involving the United
         States, any declaration of war by Congress or any other substantial
         national or international calamity or emergency if, in the judgment of
         a majority in interest of the Purchasers, including CSFBC, the effect
         of any such attack, outbreak, escalation, act, declaration, calamity or
         emergency makes it impractical or inadvisable to proceed with
         completion of the offering or sale of and payment for the Offered
         Securities.

                  (c)  The Purchasers shall have received an opinion, dated the
         Closing Date, of Vinson & Elkins L.L.P., counsel for the Company and
         the Guarantors, to the effect that:

                  the failure to be so qualified or to be in good standing

                  applicable, under the laws of the jurisdiction of its
                  organization, with the partnership power and authority to own
                  its properties and conduct its business as described in the

                  qualification, except where the failure to be so qualified or
                  to be in good standing would not, individually, or in the
                  aggregate, have a Material Adverse Effect; and to such
                  counsel's knowledge, except as disclosed in the Offering
                  Documents, all the limited liability company interests in each

                  to the Company, the Parent or any of the Parent Subsidiaries,
                  would individually or in the aggregate have a Material Adverse

                  all material respects to the description thereof contained in
                  the Offering Documents and is a valid and binding agreement of

                           (xvii) To such counsel's knowledge, neither the
                  Company, the Parent nor any of the Parent Subsidiaries is in
                  violation of its respective charter, by-laws or similar

                           (xviii) Except for the Registration Rights Agreement
                  and as disclosed in the Offering Document, to such counsel's
                  knowledge, there are no contracts, agreements or
                  understandings between the Company or any Guarantor and any
                  person granting such person the right to require the Company
                  or such Guarantor to file a registration statement under the
                  Securities Act with respect to any securities of the Company
                  or such Guarantor or to require the Company or such Guarantor
                  to include such securities with the Securities and Guarantee
                  registered pursuant to any Registration Statement;

                           (xix) Neither the Company nor any Guarantor is an
                  open-end investment company, unit investment trust or
                  face-amount certificate company that is or is required to be
                  registered under Section 8 of the United States Investment
                  Company Act of 1940 (the "Investment Company Act"); and
                  neither the Company nor any Guarantor is, and after giving
                  effect to the offering and sale of the Offered Securities
                  and the application of the proceeds thereof as described in
                  the Offering Document, neither will be, an "investment

                  the Company or the Guarantors during the period since the
                  inception of such firm's representation of the Company or the

counsel have participated in conferences with officers and representatives of
the Company, the Parent, representatives of the independent public accountants

untrue statement of a material fact or omitted to state any material fact

state therein. Such opinion may, solely as it relates to the application of laws
other than the laws of the United States and jurisdictions in which they are
admitted, to the extent such counsel deems proper and to the extent specified in
such opinion, be given in reliance on or directly from separate legal counsel
reasonably acceptable to the Purchasers and their legal counsel. Such opinion

than capital stock issued in the Parent's initial public offering), (ii) (as to
corporate subsidiaries of the Company), (iii) (as to partnership subsidiaries of
the Company), (iv) (as to limited liability company subsidiaries of the
Company), and (vi) (as to the use of proceeds in the United States) be given

         related matters as CSFBC may require, and the Company shall have
         furnished to such counsel such documents as they request for the
         purpose of enabling them to pass upon such matters.

                  (e) The Purchasers shall have received a certificate, dated
         the Closing Date, of the President or any Vice President and a
         principal financial or accounting officer of the Company in which such
         officers shall state that, to their knowledge, the representations and
         warranties of the Company in this Agreement are true and correct, that
         the Company has complied with all agreements and satisfied all
         conditions on its part to be performed or satisfied hereunder at or
         prior to the Closing Date, and that, subsequent to the respective dates
         of the most recent financial statements in the Offering Document there
         has been no material adverse change, nor any development or event
         involving a prospective material adverse change, in the condition
         (financial or other), business, properties or results of operations of
         the Company and the Parent Subsidiaries taken as a whole except as set
         forth in or contemplated by the Offering Document or as described in
         such certificate.

                  (f) The Purchasers shall have received a letter, dated the
         Closing Date, of KPMG LLP which meets the requirements of subsection
         (a) of this Section, except that the specified date referred to in such
         subsection will be a date not more than three days prior to the Closing
         Date for the purposes of this subsection.

The Company will furnish the Purchasers with such conformed copies of such
opinions, certificates, letters and documents as the Purchasers reasonably
request. CSFBC may in its sole discretion waive on behalf of the Purchasers
compliance with any conditions to the obligations of the Purchasers hereunder.

         7. INDEMNIFICATION AND CONTRIBUTION. (a) Each of the Company and the
Guarantors will indemnify and hold harmless each Purchaser, its partners,
directors and officers and each person, if any, who controls such Purchaser
within the meaning of Section 15 of the Securities Act, against any losses,
claims, damages or liabilities, joint or several, to which such Purchaser may
become subject, under the Securities Act or the Exchange Act 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 any material fact contained in the Offering Document or the
Exchange Act Reports, or arise out of or are based upon the omission or alleged
omission to state therein a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, including any losses, claims, damages or liabilities
arising out of or based upon the Company's failure to perform its obligations
under Section 5(a) of this Purchase Agreement, and will reimburse each Purchaser
for any legal or other expenses reasonably incurred by such Purchaser in
connection with investigating or defending any such loss, claim, damage,
liability or action as such expenses are incurred; provided, however, that the
Company and the Guarantors 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 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 written
information furnished to the Company by any Purchaser through CSFBC specifically
for use therein, it being understood and agreed that the only such information
consists of the information described as such in subsection (b) below.

                  (b) Each Purchaser will severally and not jointly indemnify
and hold harmless the Company and the Guarantors, their directors and officers
and each person, if any, who controls the Company and the Guarantors within the
meaning of Section 15 of the Securities Act, against any losses, claims, damages
or liabilities to which the Company or the Guarantors may become subject, under
the Securities Act or the Exchange Act 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 any material
fact contained in the Offering Document or arise out of or are based upon the
omission or the alleged omission to state therein a material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, 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 reliance upon and in conformity with written
information furnished to the Company by such Purchaser through CSFB specifically
for use therein, and will reimburse any legal or other expenses reasonably
incurred by the Company in connection with investigating or defending any such
loss, claim, damage, liability or action as such expenses are incurred, it being
understood and agreed that the only such information furnished by any Purchaser
consists of the following information in the Offering Document furnished on
behalf of each Purchaser: paragraph 10 under the caption "Plan of Distribution";
provided, however, that the Purchasers shall not be liable for any losses,
claims, damages or liabilities arising out of or based upon the Company's
failure to perform its obligations under Section 5(a) of this Agreement.

                  (c) Promptly after receipt by an indemnified party under this
Section 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 subsection (a) or (b) above, notify the indemnifying party of the
commencement thereof; but the omission so to notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under subsection (a) or (b) above. In case any such action is
brought against any indemnified party and it notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel
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 will not be liable to such
indemnified party under this Section for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of

                                       19

<Page>

any pending or threatened action 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 (i) an unconditional
release of such indemnified party from all liability on any claims that are
the subject matter of such action and (ii) does not include a statement as to
or an admission of fault, culpability or failure to act by or on behalf of
any indemnified party.

                  (d) If the indemnification provided for in this Section is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to in subsection (a) or (b) above (i) in
such proportion as is appropriate to reflect the relative benefits received by
the Company and the Guarantors on the one hand and the Purchasers on the other
from the offering of the Offered 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 and the Guarantors on the one
hand and the Purchasers on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities as well
as any other relevant equitable considerations. The relative benefits received
by the Company and the Guarantors on the one hand and the Purchasers on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Company bear to
the total discounts and commissions received by the Purchasers from the Company
under this Agreement. The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company and the Guarantors or the Purchasers and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission. The amount paid by an
indemnified party as a result of the losses, claims, damages or liabilities
referred to in the first sentence of this subsection (d) shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any action or claim which is
the subject of this subsection (d). Notwithstanding the provisions of this
subsection (d), no Purchaser shall be required to contribute any amount in
excess of the amount by which the total discounts, fees and commissions received
by such Purchaser exceeds the amount of any damages which such Purchaser has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.

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

         8. DEFAULT OF PURCHASERS. If any Purchaser or Purchasers default in
their obligations to purchase Offered Securities hereunder and the aggregate
principal amount of Offered Securities that such defaulting Purchaser or
Purchasers agreed but failed to purchase does not exceed 10% of the total
principal amount of Offered Securities, CSFBC may make arrangements satisfactory
to the Company for the purchase of such Offered Securities by other persons,
including any of the Purchasers, but if no such arrangements are made by the
Closing Date, the non-defaulting Purchasers shall be obligated severally, in
proportion to their respective commitments hereunder, to purchase the Offered
Securities that such defaulting Purchasers agreed but failed to purchase. If any
Purchaser or Purchasers so default and the aggregate principal amount of Offered
Securities with respect to which such default or defaults occur exceeds 10% of
the total principal amount of Offered Securities and arrangements satisfactory
to CSFBC and the Company for the purchase of such Offered Securities by other
persons are not made within 36 hours after such default, this Agreement will
terminate without liability on the part of any non-defaulting Purchaser, the
Company or any Guarantor, except as provided in Section 9. As used in this
Purchase Agreement, the term "PURCHASER" includes any

                                       20

person substituted for a Purchaser under this Section. Nothing herein will
relieve a defaulting Purchaser from liability for its default.

         9. SURVIVAL OF CERTAIN REPRESENTATIONS AND OBLIGATIONS. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Purchasers set forth in or made
pursuant to this Purchase Agreement will remain in full force and effect,
regardless of any investigation, or statement as to the results thereof, made by
or on behalf of any Purchaser, the Company or any of their respective
representatives, officers or directors or any controlling person, and will
survive delivery of and payment for the Offered Securities. If this Agreement is
terminated pursuant to Section 8 or if for any reason the purchase of the
Offered Securities by the Purchasers is not consummated, the Company shall
remain responsible for the expenses to be paid or reimbursed by it pursuant to
Section 5 and the respective obligations of the Company, the Guarantors and the
Purchasers pursuant to Section 7 shall remain in effect. If the purchase of the
Offered Securities by the Purchasers is not consummated for any reason other
than solely because of the termination of this Agreement pursuant to Section 8
or the occurrence of any event specified in clause (C), (D) or (E) of Section
6(b)(ii), the Company and the Guarantors, jointly and severally, will reimburse
the Purchasers for all out-of-pocket expenses (including fees and disbursements
of counsel) reasonably incurred by them in connection with the offering of the
Offered Securities.

         10. NOTICES. All communications hereunder will be in writing and, if

pursuant to Section 7 will be mailed, delivered or telegraphed and confirmed to
such Purchaser.

         11. SUCCESSORS. This Purchase Agreement will inure to the benefit of
and be binding upon the parties hereto and their respective successors and the
controlling persons referred to in Section 7, and no other person will have any
right or obligation hereunder, except that holders of Offered Securities shall
be entitled to enforce the agreements for their benefit contained in the second
and third sentences of Section 5(b) hereof against the Company as if such
holders were parties hereto.

         12. REPRESENTATION OF PURCHASERS. The Representatives will act for the
several Purchasers in connection with this purchase, and any action under this
Agreement taken by the Representatives jointly or by CSFBC will be binding upon
all the Purchasers.

         13. COUNTERPARTS. This Agreement may be executed 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 Agreement.

         14. APPLICABLE LAW. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of New York without regard to
principles of conflicts of laws.

         Each of the Company and the Guarantors hereby submits to the
non-exclusive jurisdiction of the Federal and state courts in the Borough of
