Ladies and Gentlemen:

                  United Refining Company (the "Company"), a Pennsylvania

                  1. ISSUANCE OF NOTES. The Company and Kiantone Pipeline
Corporation, Kiantone Pipeline Company, United Jet Center, Inc., United Refining
Company of Pennsylvania, Kwik-Fil, Inc., Kwik Fill, Inc., Independent Gasoline
and Oil Company of Rochester, Inc., Bell Oil Corp., PPC, Inc., Super Test
Petroleum, Inc., and Vulcan Asphalt Refining Corporation (collectively, the
"Subsidiary Guarantors") proposes to issue and sell to Dillon, Read & Co. Inc.
and Bear, Stearns & Co. Inc. (the "Initial Purchasers") an aggregate of
$200,000,000 principal amount of 10 3/4% Series A Senior Notes due 2007 (the
"Senior Notes"). The Senior Notes will be issued pursuant to an indenture (the
"Indenture"), to be dated the Closing Date (as defined below), by and among the
Company, the Subsidiary Guarantors and IBJ Schroder Bank & Trust Company, as
trustee (the "Trustee"). The Company's obligations under the Senior Notes will
be unconditionally guaranteed on a senior basis by each of the Subsidiary
Guarantors pursuant to each of their guarantees (the "Subsidiary Guarantees").
All references herein to the Senior Notes include the related guarantees, unless
the context otherwise requires. Capitalized terms used but not otherwise defined
herein shall have the meanings given to such terms in the Indenture or the
Offering Memorandum (as defined below).

                  The Senior Notes will be offered and sold to the Initial
Purchasers pursuant to an exemption from the registration 
   2
                                      -2-


requirements under the Securities Act of 1933, as amended (the "Act"). The
Company has prepared a preliminary offering memorandum, dated May 16, 1997 (the
"Preliminary Offering Memorandum"), and a final offering memorandum, dated and
available for distribution on the date hereof (the "Offering Memorandum"),
relating to the Company, the Subsidiary Guarantors and the Senior Notes.

                  The Initial Purchasers have advised the Company that the
Initial Purchasers intend, as soon as it deems advisable after this Purchase
Agreement has been executed and delivered, to resell (the "Exempt Resales") the
Senior Notes purchased by the Initial Purchasers under this Purchase Agreement
(this "Agreement") in private sales exempt from registration under the Act on
the terms set forth in the Offering Memorandum, as amended or supplemented,
solely to (i) persons whom the Initial Purchasers reasonably believe to be
"qualified institutional buyers," as defined in Rule 144A under the Act
("QIBs"), (ii) institutional "accredited investors" (as defined in Rule
501(a)(1), (2), (3) or (7) under Regulation D of the Act) that make certain
representations and agreements (each, an "Institutional Accredited Investor")
and (iii) other eligible purchasers pursuant to offers and sales that occur
outside the U.S. within the meaning of Regulation S under the Act; the persons
specified in clauses (i)-(iii) are sometimes collectively referred to herein as
the "Eligible Purchasers."

                  Holders (including subsequent transferees) of the Senior Notes
will have the registration rights set forth in the registration rights agreement
(the "Registration Rights Agreement"), to be dated the Closing Date, in the form
of Exhibit A to this Agreement, for so long as such Senior Notes constitute
"Transfer Restricted Securities" (as defined in the Registration Rights
Agreement). Pursuant to the Registration Rights Agreement, the Company and the
Subsidiary Guarantors will agree to (A) file with the Securities and Exchange
Commission (the "Commission"), under the circumstances set forth in the
Registration Rights Agreement, (i) a registration statement under the Act (the
"Exchange Offer Registration Statement") relating to the 10 3/4% Series B Senior
Notes due 2007 (the "Series B Senior Notes" and, together with the Senior Notes,
the "Notes," which term includes the Subsidiary Guarantees related thereto) to
be offered in exchange for the Senior Notes (the "Exchange Offer") and/or (ii) a
shelf registration statement pursuant to Rule 415 under the 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 Senior Notes, and (B) use their best efforts to 




   3
                                      -3-

cause such Registration Statements to be declared effective as soon as
practicable. This Agreement, the Escrow Agreement, the Notes, the Indenture and
the Registration Rights Agreement are hereinafter sometimes referred to
collectively as the "Operative Documents."

                  A portion of the net proceeds from the sale of the Senior
Notes will be deposited with IBJ Schroder Bank & Trust Company, as escrow agent
(the "Escrow Agent") as described in the Offering Memorandum and in accordance
with the Escrow Agreement and the Indenture.

                  Upon original issuance of the Senior Notes and until such time
as the same is no longer required under the applicable requirements of the Act,
the Senior Notes shall bear the following legend:

representations, warranties and covenants contained in this Agreement, and
subject to the terms and conditions contained in this Agreement, the Company

Company's obligations under the Notes.

                  3. DELIVERY AND PAYMENT. Delivery of, and payment of the

request upon at least one business day's notice prior to the Closing Date,
having an aggregate principal amount corresponding to the aggregate principal
amount of the Senior Notes sold pursuant to Exempt Resales to QIBs and
Institutional Accredited Investors, in the case of the Notes in global form, and

pursuant to Regulation S, shall be delivered by the Company to the Initial
Purchasers (or as the Initial Purchasers direct), against payment by the Initial
Purchasers of the purchase price therefor by means of transfer of immediately
available funds (including book transfer) reasonably acceptable to the Initial
Purchasers and the Company to the order of the Company. The Senior Notes in

                  4. AGREEMENTS OF THE ISSUERS. The Company and the Subsidiary
Guarantors covenant and agree with the Initial Purchasers as follows:

                  (a) To furnish the Initial Purchasers and those persons
         identified by the Initial Purchasers, without charge, with as many
         copies of the Preliminary Offering Memorandum and the Offering
         Memorandum, and any amendments or supplements thereto, as the Initial
         Purchasers may reasonably request for purposes contemplated by the Act.
         The Company consents to the use of the Preliminary Offering Memorandum
         and the Offering Memorandum, and any amendments and supplements thereto
         required pursuant to this Agreement, by the Initial Purchasers in
         connection with Exempt Resales that are in compliance with Section 5(b)
         of this Agreement.

                  (b) Not to amend or supplement the Offering Memorandum prior
         to the Closing Date unless the Initial Purchasers shall previously have
         been advised of, and shall not have objected to (any such objection not
         to be unreasonable), such amendment or supplement within a reasonable
         time, but in any event not longer than five days after being furnished
         with a copy of such amendment or supplement. The Company shall promptly
         prepare, upon the Initial Purchasers' reasonable request, any amendment
         or supplement to the Offering Memorandum that may be necessary or
         advisable in connection with Exempt Resales.

                  (c) If, during the time that an Offering Memorandum is
         required to be delivered in connection with any Exempt Resales or
         market-making transactions after the date of this Agreement and prior
         to the consummation of the Exchange Offer, any event shall occur that,
         in the judgment of the Company or in the judgment of counsel to the
         Initial Purchasers, makes any statement of a material fact in the
         Offering Memorandum untrue or that requires the making of any additions
         to or changes in the Offering Memorandum in order to make the
         statements in the Offering Memorandum, in the light of the
         circumstances under which they are made, not misleading, or if it is
         necessary to amend or supplement the Offering Memorandum to comply with
         all applicable laws, the Company shall promptly notify the Initial
         Purchasers of such event and prepare an appropriate amendment or
         supplement to the Offering Memorandum so that (i) the statements in the
         Offering Memorandum as amended or supplemented will, in the light of
         the circumstances at the time that the Offering Memorandum is deliv-
   6

         of such jurisdictions as the Initial Purchasers may request and to
         continue such qualification in effect so long as required for the
         Exempt Resales. Notwithstanding the foregoing, the Company shall not be
         required to qualify as foreign corporations in any jurisdiction in
         which it is not so qualified or to file a general consent to service of
         process in any such jurisdiction or subject itself to taxation in
         excess of a nominal dollar amount in any such jurisdiction where it is
         not then so subject.

                  (e) Whether or not the transactions contemplated by this
         Agreement are consummated or this Agreement becomes effective or is
         terminated, to pay all costs, expenses, fees, disbursements (including
         fees, expenses and disbursements of counsel) and stamp, documentary or

         plement or amendment thereto. No order asserting that any of the
         transactions contemplated by this Agreement are subject to the
         registration requirements of the Act has been issued or threatened.

                   (ii) There are no securities of either the Company or any of
         the Subsidiary Guarantors that are listed on a national securities
         exchange registered under Section 6 of the Exchange Act or that are
         quoted in a United States automated interdealer quotation system.

         Subsidiary Guarantors, free and clear of any pledge, fiduciary
         transfer, security interest, claim, lien, limitation on voting rights

         and validly issued, fully paid and nonassessable and will not have been
         issued in violation of, or subject to, any preemptive or similar
         rights. There will not be any outstanding rights, warrants or options
         to acquire, or instruments convertible into or exchangeable for, any
         shares of capital stock or other equity interest of any Subsidiary
         Guarantor.

         authorizations, approvals, orders, licenses, certificates and permits
         of and from regulatory or governmental officials, bodies and tribunals,
         except where the failure to obtain such authorizations, approvals,
         orders, licenses, certificates and permits would not result in a
         Material Adverse Effect, to (a) carry on its business as it is
         currently being conducted and as described in the Offering Memorandum
         and (b) own, lease, license and operate its respective properties in
         accordance with its business as currently conducted. The Company and
         each of the Subsidiary Guarantors is duly qualified and in good
         standing as a foreign corporation authorized to do business in each
         jurisdiction in which the nature of its business or its ownership or
         leasing of property requires such qualification, except where the
         failure to be so qualified would not, either individually or in the
         aggregate, result in a Material Ad-
   10

         verse Effect. A "Material Adverse Effect" means any material adverse

         and authority to issue, sell and deliver the Notes and each of the
         Subsidiary Guarantors has all requisite corporate power and authority
         to execute, deliver and perform all of its obligations under the
         Subsidiary Guarantees.

                   (vi) This Agreement has been duly and validly authorized,
         executed and delivered by the Company and each of the Subsidiary
         Guarantors.

         ing obligation of the Company and each of the Subsidiary Guarantors,

         Pennsylvania, as applicable, in accordance with their terms, except
         that enforceability of the New Bank Credit Facility may be limited by

         affecting the enforceability of creditors' rights generally and by
         general principles of equity and the discretion of the court before

         be brought.

                   (xv) The execution, delivery or performance by the Company
         and the Subsidiary Guarantors (as applicable) of this Agreement and the
         other Operative Documents to which they are a party does not or will
         not violate, conflict with or constitute a breach of any of the terms
         or provisions of, or a default under (or an event that with notice or
         the lapse of time, or both, would constitute a default), or require
         consent under, or result in the creation or imposition of a lien,
         charge or encumbrance on any property or assets of the Company or any
         of the Subsidiary Guarantors or an acceleration of any indebtedness of
         the Company or any of the Subsidiary Guarantors pursuant to, (i) the
         charter, constitutive documents or bylaws of the Company or any of the
         Subsidiary Guarantors, (ii) any Agreement except for the Existing
         Facility as defined and described in the Offering Memorandum under the
         caption "Description of Certain Indebtedness," (iii) any law, statute,
         rule or regulation applicable to the Company or any of the Subsidiary
         Guarantors or their assets or properties or (iv) any judgment, order or
         decree of any domestic or foreign court or governmental agency or
         authority having jurisdiction over the Company or any of the Subsidiary
         Guarantors or their assets or properties that, in the case of clauses
         (ii), (iii) and (iv) above, would result in a Material Adverse Effect.

         pursuant to the Registration Rights Agreement or (iii) such as may be

         Agreement or any of the other Operative Documents, the execution,
         delivery and performance of the New Bank Credit Facility or any of the
         transactions contemplated thereby.

                  (xvi) The Company has delivered to the Initial Purchasers true
         and correct executed copies of the New Bank Credit Facility and there
         have been no amendments, alterations or modifications thereto or
         waivers of any of the provisions thereof. The representations and
         warranties of the Company set forth in the New Bank Credit Facility
         will be true and correct as of the Closing Date (except to the extent
         that any such representation or warranty was expressly made as of any
         other date, in which case such representation and warranty was true and
         correct as of such date).

                 (xvii) There is (i) no action, suit or proceeding before or by
         any court, arbitrator or governmental agency, body or official,
         domestic or foreign, now pending or, to the knowledge of the Company or
         the Subsidiary Guarantors, threatened or contemplated, to which the
         Company or any of the Subsidiary Guarantors is or may be a party or to
         which the business, assets or property of such person is or may be
         subject, (ii) no statute, rule, regulation or order that has been
         enacted, adopted or issued or, to the knowledge of the Company or the

         or order of any nature by a federal or state court or foreign court of
         competent jurisdiction to which the Company or any of the Subsidiary
         Guarantors is or may be subject that (x) in the case of clause (i)
         above, if determined adversely to the Company or the Subsidiary
         Guarantors, would 
   15
                                      -15-


         be reasonably likely to, either individually or in the aggregate, (1)
         result in a Material Adverse Effect, or (2) interfere with or adversely
         affect the issuance of the Notes or the Subsidiary Guarantees in any
         jurisdiction or adversely affect the consummation of the transactions
         contemplated by any of the Operative Documents and (y) in the case of
         clauses (ii) and (iii) above, would, either individually or in the

         date hereof has been, or will prior to the Closing Date be, complied
         with in all material respects.

                (xviii) No labor disturbance by the employees of the Company or
         any of the Subsidiary Guarantors exists or, to the actual knowledge of
         the Company or the Subsidiary Guarantors, is imminent, that might
         reasonably be expected to have a Material Adverse Effect; the Company
         and the Subsidiary Guarantors are in compliance in all respects with,
         as applicable and except where a failure to so comply would not have a
         Material Adverse Effect, 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 the
         Subsidiary Guarantors would have any liability; none of the Company or
         the Subsidiary Guarantors has incurred or expects to incur liability
         under (i) Title IV of ERISA with respect to termination of, or
         withdrawal from, any "pension plan" or (ii) Sections 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" that is maintained or contributed to by the Company or
         the Subsidiary Guarantors that is intended to be qualified under
         Section 401(a) of the Code is so qualified and nothing has occurred,
         whether by action or by failure to act, that would cause the loss of
         such qualification.

                  (xix) Except as set forth in the Offering Memorandum, the
         Company and each of the Subsidiary Guarantors (i) is 
   16
                                      -16-


         in compliance with, or not subject to costs or liabilities under, all
         local, state, provincial, federal and foreign laws, regulations, rules
         of common law, orders and decrees, as in effect as of the date hereof,
         and any present judgments and injunctions issued or promulgated
         thereunder relating to pollution or protection of public and employee
         health and safety and the environment applicable to it or its business
         or operations or ownership or use of its property ("Environmental
         Laws"), other than noncompliance or such costs or liabilities that
         would not result in a Material Adverse Effect, and (ii) possesses all
         permits, licenses or other approvals required under applicable
         Environmental Laws, other than permits, licenses or approvals the lack
         of which would not result in a Material Adverse Effect. All currently
         pending and, to their knowledge, threatened proceedings, notices of
         violation, demands, notices of potential responsibility or liability,
         suits and existing environmental conditions with respect to which the
         Company or the Subsidiary Guarantors could reasonably be expected to
         have any liability are fully and accurately described in all material
         respects in the Offering Memorandum except as would not have a Material
         Adverse Effect.

                   (xx) The Company and each of the Subsidiary Guarantors has
         (i) good and marketable title to all of the properties and assets
         described in the Offering Memorandum as owned by it and good and
         marketable title to the leasehold estates in the real and personal
         property described in the Offering Memorandum as leased by it, free and
         clear of all Liens (as defined in the Indenture), except for Liens
         described in the Offering Memorandum, Liens permitted under the
         Indenture and such Liens as would not have a Material Adverse Effect,
         (ii) all licenses, certificates, permits, authorizations, approvals,
         franchises and other rights from, and has made all declarations and
         filings with, all federal, state, local and foreign authorities, all
         self-regulatory authorities and all courts and other tribunals (each,
         an "Authorization") necessary to engage in the business conducted by it
         in the manner described in the Offering Memorandum, except where
         failure to hold such Authorizations would not have a Material Adverse
         Effect, and (iii) no reason to believe that any governmental body or
         agency, domestic or foreign, is considering limiting, suspending or
         revoking any such Authorization, other than revocations that would not
         result in a Material Adverse Effect. Except where the failure to be in
         full force and effect would not have a Material Adverse Effect, all
         such 
   17
                                      -17-


         Authorizations are valid and in full force and effect and the Company
         and each of the Subsidiary Guarantors is in compliance in all material
         respects with the terms and conditions of all such Authorizations and
         with the rules and regulations of the regulatory authorities having
         jurisdiction with respect to such Authorizations. All leases to which
         the Company or any of the Subsidiary Guarantors is a party are valid
         and binding, except as such enforceability may be limited by
         bankruptcy, insolvency, reorganization, moratorium or similar laws now
         or hereafter affecting the enforcement of creditors' rights generally
         and by general principles of equity and the discretion of the court
         before which any proceedings therefor may be brought and no default has
         occurred and is continuing thereunder, other than defaults that would
         not result in a Material Adverse Effect.

                  (xxi) The Company and each of the Subsidiary Guarantors owns,
         possesses or has the right to employ all patents, patent rights,
         licenses, inventions, copyrights, know-how (including trade secrets and
         other unpatented and/or unpatentable proprietary or confidential
         information, systems or procedures), trademarks, service marks and
         trade names (collectively, the "Intellectual Property") necessary to
         conduct the businesses operated by it as described in the Offering
         Memorandum, other than such Intellectual Property the failure to own,
         possess or have the right to employ would not result in a Material
         Adverse Effect. None of the Company or the Subsidiary Guarantors has
         received any notice of infringement of or conflict with (and neither
         knows of any such infringement or a conflict with) asserted rights of
         others with respect to any of the foregoing that, if such assertion of
         infringement or conflict were sustained, would have a Material Adverse
         Effect. The use of the Intellectual Property in connection with the
         business and operations of the Company and the Subsidiary Guarantors
         does not infringe on the rights of any person.

                 (xxii) All tax returns required to be filed by the Company and
         each of the Subsidiary Guarantors have been filed in all jurisdictions
         where such returns are required to be filed; and all taxes, including
         withholding taxes, penalties and interest, assessments, fees and other
         charges due or claimed to be due from such entities or that are due and
         payable have been paid, other than those being contested in good faith
         and for which reserves have been provided in accordance with generally
         accepted accounting 
   18
                                      -18-


         principles or those currently payable without penalty or interest,
         except where the failure to make any such filing or payment would not
         have a Material Adverse Effect. To the knowledge of the Company and
         each of the Subsidiary Guarantors, there are no material proposed
         additional tax assessments against any of them or their assets or
         property.

                (xxiii) None of the Company or the Subsidiary Guarantors is an
         "investment company" or a company "controlled" by an "investment
         company" within the meaning of the Investment Company Act of 1940, as
         amended (the "Investment Company Act"), or analogous foreign laws and
         regulations.

                 (xxiv) Except with respect to the Notes, there are no holders
         of securities of the Company or any of the Subsidiary Guarantors who
         have the right to request or demand that the Company or any of the
         Subsidiary Guarantors register under the Act or analogous foreign laws
         and regulations any of such securities held by any such holders.

                  (xxv) The Company and each of the Subsidiary Guarantors
         maintains a system of internal accounting controls sufficient to
         provide reasonable assurance that: (A) transactions are executed in
         accordance with management's general or specific authorizations; (B)
         transactions are recorded as necessary to permit preparation of its
         financial statements in conformity with United States generally
         accepted accounting principles and to maintain accountability for
         assets; (C) access to assets is permitted only in accordance with
         management's general or specific authorization; and (D) the recorded
         accountability for its assets is compared with the existing assets at
         reasonable intervals and appropriate action is taken with respect to
         any differences.

                 (xxvi) The Company and each of the Subsidiary Guarantors
         maintains insurance covering its properties, assets, operations,
         personnel and businesses, and such insurance is of such type and in
         such amounts in accordance with customary industry practice to protect
         the Company and the Subsidiary Guarantors and their businesses. None of
         the Company or the Subsidiary Guarantors has received notice from any
         insurer or agent of such insurer that any material capital improvements
         or other material expenditures will have to be made in order to
         continue any insurance maintained by any of them other than capital
         improvements 
   19
                                      -19-



         and other expenditures that have been budgeted by the Company or the
         Subsidiary Guarantors, as the case may be.

                (xxvii) None of the Company, the Subsidiary Guarantors or their
         Affiliates (as defined in Rule 501(b) of Regulation D under the Act)
         has (A) taken, directly or indirectly, any action designed to, or that
         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 Senior Notes or (B) since the date of the
         Preliminary Offering Memorandum (x) sold, bid for, purchased or paid
         any person any compensation for soliciting purchases of the Senior
         Notes in a manner that would require registration of the Senior Notes
         under the Act or (y) paid or agreed to pay to any person any
         compensation for soliciting another to purchase any other securities of
         the Company or any of the Subsidiary Guarantors in a manner that would
         require registration of the Senior Notes under the Act.

               (xxviii) No registration under the Act of the Senior Notes is
         required for the sale of the Senior Notes to the Initial Purchasers as
         contemplated by this Agreement or for the Exempt Resales, assuming in
         each case that (A) the purchasers who buy the Senior Notes in the
         Exempt Resales are either QIBs or Accredited Investors and (B) the
         accuracy of and compliance with the Initial Purchasers'
         representations, warranties and covenants contained in Section 5(b) of
         this Agreement. No form of general solicitation or general advertising
         (prohibited by the Act in connection with offers or sales such as the
         Exempt Resales) was used by the Company, any of the Subsidiary
         Guarantors or any of their representatives (provided that no
         representation is being made in this paragraph (xxviii) with respect to
         the Initial Purchasers) in connection with the offer and sale of any of
         the Senior Notes or in connection with Exempt Resales, including, but
         not limited to, articles, notices or other communications published in
         any newspaper, magazine or similar medium or broadcast over television
         or radio, or any seminar or meeting whose attendees have been invited
         by any general solicitation or general advertising.

                 (xxix) The execution and delivery of this Agreement, the other
         Operative Documents and the sale of the Notes and Subsidiary Guarantees
         to be purchased by the QIBs and the Accredited Investors will not
         involve any prohibited transaction within the meaning of Section 406(a)
         of ERISA
   20
                                      -20-


         or Section 4975(c)(1)(A)-(D) of the Code. The representation made by
         the Company and each of the Subsidiary Guarantors in the preceding
         sentence is made in reliance upon and subject to the accuracy of, and
         compliance with, the representations and covenants made or deemed made
         by the QIBs and the Accredited Investors as set forth in the Offering
         Memorandum under the caption "Transfer Restrictions."

                  (xxx) Each of the Preliminary Offering Memorandum and the
         Offering Memorandum, as of its date, and each amendment or supplement
         thereto, as of its date, contains the information specified in, and
         meets the requirements of, Rule 144A(d)(4) under the Act.

                 (xxxi) As of February 28, 1997, neither the Company nor any of
         the Subsidiary Guarantors had any material liabilities or obligations,
         direct or contingent, that were not set forth in the Company's
         consolidated balance sheet as February 28, 1997, or in the notes
         thereto. Since February 28, 1997 and up to the Closing Date, except as
         set forth in the Offering Memorandum, (a) none of the Company or the
         Subsidiary Guarantors has (1) incurred any liabilities or obligations,
         direct or contingent, that are not in the ordinary course of business
         that would have a Material Adverse Effect or (2) entered into any
         material transaction not in the ordinary course of business, and (b)
         there has not been any event or development in respect of the business,
         development or financial condition of the Company that would, either
         individually or in the aggregate, result in a Material Adverse Effect.

                (xxxii) Neither the Company nor any of the Subsidiary Guarantors
         (nor any agent thereof acting its behalf has taken, and none of them
         will take, any action that might cause this Agreement or the issuance
         or sale of the Notes to violate Regulation G (12 C.F.R. Part 207),
         Regulation T (12 C.F.R. Part 220), Regulation U (12 C.F.R. Part 221) or
         Regulation X (12 C.F.R. Part 224) of the Board of Governors of the
         Federal Reserve System or analogous foreign laws and regulations, in
         each case as in effect, or as the same may hereafter be in effect, on
         the Closing Date.

               (xxxiii) The accountants who have certified or shall certify the
         financial statements included or to be included as part of the Offering
         Memorandum are independent accountants within the meaning of the Act.
         The historical financial statements of the Company comply as to form in
   21
                                      -21-



         all material respects with the requirements applicable to registration
         statements on Form S-1 under the Act and present fairly in all material
         respects the consolidated financial position and results of operations
         of the Company at the respective dates and for the respective periods
         indicated. Such financial statements have been prepared in accordance
         with United States generally accepted accounting principles applied on
         a consistent basis throughout the periods presented (except as
         disclosed in the Offering Memorandum) and comply as to form with the
         rules and regulations promulgated under the Act. The pro forma
         financial statements included in the Offering Memorandum have been
         prepared on a basis consistent with such historical statements, except
         for the pro forma adjustments specified therein, and give effect to
         assumptions made on a reasonable basis and present fairly in all
         material respects the historical and proposed transactions contemplated
         by the Offering Memorandum, this Agreement and the other Operative
         Documents. The other financial and statistical information and data
         included in the Offering Memorandum, historical and pro forma, are
         accurately presented in all material respects and prepared on a basis
         consistent with the financial statements and the books and records of
         the Company and the Subsidiary Guarantors.

                (xxxiv) None of the Company or the Subsidiary Guarantors (A) is
         "insolvent" as that term is defined in Section 101(32) of the United
         States Bankruptcy Code (the "Bankruptcy Code") (11 U.S.C. Section
         101(32)), Section 2 of the Uniform Fraudulent Transfer Act ("UFTA") or
         Section 2 of the Uniform Fraudulent Conveyance Act ("UFCA"), (B) has
         "unreasonably small capital" as that term is used in Section
         548(a)(2)(ii) of the Bankruptcy Code or Section 5 of the UFCA, (C) is
         engaged or about to engage in a business or transaction for which its
         remaining property is "unreasonably small" in relation to the business
         or transaction as that term is used in Section 4 of the UFTA or (D) is
         unable to pay its debts as they mature or become due, within the
         meaning of Section 548(a)(2)(B)(iii) of the Bankruptcy Code, Section 4
         of the UFTA and Section 6 of the UFCA. The Company and each of the
         Subsidiary Guarantors now owns assets having a value both at "fair
         valuation" and at "present fair saleable value" greater than the amount
         required to pay its "debts" as such terms are used in Section 2 of the
         UFTA and Section 2 of the UFCA. None of the Company or the Subsidiary
         Guarantors will be rendered insolvent by the execution and delivery of
         any of 
   22
                                      -22-


         the Operative Documents or the New Bank Credit Facility or by the
         transactions contemplated hereunder or thereunder.

                 (xxxv) Except as described in the section entitled "Certain
         Relationships and Related Transactions" in the Offering Memorandum,
         there are no contracts, agreements or understandings between the
         Company or any of the Subsidiary Guarantors and any other person other
         than the Initial Purchasers that would give rise to a valid claim
         against the Company, the Subsidiary Guarantors or the Initial
         Purchasers for a brokerage commission, finder's fee or like payment in
         connection with the issuance, purchase and sale of the Notes.

                (xxxvi) The Company has the authorized, issued and outstanding
         capitalization set forth in the Offering Memorandum under the caption
         "Capitalization"; all of the outstanding capital stock of the Company
         has been duly authorized and validly issued, is or will be on the
         Closing Date fully paid and nonassessable and was not issued in
         violation of any preemptive or similar rights.

               (xxxvii) The statistical and market-related data included in the
         Offering Memorandum are based on or derived from sources that the
         Company believes to be reliable and accurate in all material respects
         and represent the Company's good faith estimates that are made on the
         basis of data derived from such sources.

              (xxxviii) Each certificate signed by any officer of the Company or
         any of the Subsidiary Guarantors and delivered to the Initial
         Purchasers or counsel for the Initial Purchasers pursuant to, or in
         connection with, this Agreement shall be deemed to be a representation
         and warranty by the Company or such Subsidiary Guarantor to the Initial
         Purchasers as to the matters covered by such certificate.

                  The Company and each of the Subsidiary Guarantors acknowledges
that the Initial Purchasers and, for purposes of the opinions to be delivered to
the Initial Purchasers pursuant to Section 8 of this Agreement, the various law
firms acting as counsel to the Company and each of the Subsidiary Guarantors and
counsel to the Initial Purchasers will rely upon the accuracy and truth of the
foregoing representations and the Company and each Subsidiary Guarantor hereby
consent to such reliance.

                  (b) The Initial Purchasers represent, warrant and covenant (as
to themselves only) to the Company that they are 
   23
                                      -23-


QIBs with such knowledge and experience in financial and business matters as are
necessary in order to evaluate the merits and risks of an investment in the
securities. The Initial Purchasers represent, warrant and agree (as to
themselves only) with the Company that (i) they have not and will not solicit
offers for, or offer or sell, the Notes by any form of general solicitation or
general advertising (as those terms are used in Regulation D under the Act) or
in any manner involving a public offering within the meaning of Section 4(2) of
the Act and (ii) they have and will solicit offers for the Notes only from, and
will offer the Notes only to, (x) persons whom the Initial Purchasers reasonably
believe to be QIBs or, if any such person is buying for one or more
institutional accounts for which such person is acting as fiduciary or agent,
only when such person has represented to the Initial Purchasers that each such
account is a QIB to whom notice has been given that such sale or delivery is
being made in reliance on Rule 144A, and, in each case, in transactions under
Rule 144A, (y) a limited number of other institutional investors reasonably
believed by the Initial Purchasers to be Institutional Accredited Investors
that, prior to their purchase of the Notes, deliver to the Initial Purchasers a
letter containing the representations and agreements set forth in Annex C to the
Offering Memorandum or (z) persons other than U.S. persons outside the U.S. in
reliance on Regulation S.

                  The Initial Purchasers represent and warrant that the source
of funds being used by them to acquire the Notes does not include the assets of
any "employee benefit plan" (within the meaning of Section 3 of ERISA) or any
"plan" (within the meaning of Section 4975 of the Code).

                  The Initial Purchasers understand that the Company and, for
purposes of the opinion to be delivered to them pursuant to Section 8(f) hereof,
counsel to the Company will rely upon the accuracy and truth of the foregoing
representations, and the Initial Purchasers hereby consent to such reliance.

                  6. INDEMNIFICATION. (a) Each of the Company and the Subsidiary
Guarantors, on a joint and several basis, agrees to indemnify and hold harmless
the Initial Purchasers, each person, if any, who controls the Initial Purchasers
within the meaning of Section 15 of the Act or Section 20(a) of the Exchange
Act, the agents, employees, officers and directors of the Initial Purchasers and
the agents, employees, officers and directors of any such controlling person
from and against any and all losses, liabilities, claims, damages and expenses
whatsoever (including but not limited to reasonable attorneys' fees
   24
                                      -24-


and any and all reasonable expenses whatsoever incurred in investigating,
preparing or defending against any litigation, commenced or threatened, or any
claim whatsoever, and any and all reasonable amounts paid in settlement of any
claim or litigation) to which they or any of them may become subject under the
Act, the Exchange Act or otherwise insofar as such losses, liabilities, claims,
damages or expenses (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in the Preliminary Offering Memorandum or the Offering Memorandum, or
in any supplement thereto or amendment thereof, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading; provided,
however, that the Company and Subsidiary Guarantors will not be liable (i) in
any such case to the extent, but only to the extent, that any such loss,
liability, claim, damage or expense arises out of or is based upon any such
untrue statement or alleged untrue statement or omission or alleged omission
made therein in reliance upon and in conformity with written information
relating to the Initial Purchasers furnished to the Company by or on behalf of
the Initial Purchasers expressly for use therein or (ii) with respect to the
Preliminary Offering Memorandum, to the extent that any such loss, claim, damage
or liability results solely from an untrue statement of a material fact
contained in, or the omission of a material fact from, such preliminary Offering
Memorandum that was corrected in the final Offering Memorandum, if the Company
or the Subsidiary Guarantors shall sustain the burden of proving that such
Indemnified Person sold Notes to the person alleging such loss, claim, damage or
liability without sending or giving, at or prior to the written confirmation of
such sale, a copy of the Prospectus or of the Offering Memorandum as then
amended or supplemented even though the Company and the Subsidiary Guarantors
had previously furnished copies thereof to such Indemnified Person. This
indemnity agreement will be in addition to any liability that the Company may
otherwise have, including, but not limited to, under this Agreement.

                  (b) The Initial Purchasers agree, severally and not jointly,
to indemnify and hold harmless the Company, each person, if any, who controls
the Company within the meaning of Section 15 of the Act or Section 20(a) of the
Exchange Act, and each of its agents, employees, officers and directors and the
agents, employees, officers and directors of such controlling person from and
against any losses, liabilities, claims, damages and reasonable expenses
whatsoever (including but not lim-
   25
                                      -25-


ited to reasonable attorneys' fees and any and all reasonable expenses
whatsoever incurred in investigating, preparing or defending against any
litigation, commenced or threatened, or any claim whatsoever and any and all
reasonable amounts paid in settlement of any claim or litigation) to which they
or either of them may become subject under the Act, the Exchange Act or
otherwise insofar as such losses, liabilities, claims, damages or expenses (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of a material fact contained in the Preliminary
Offering Memorandum or the Offering Memorandum, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, in each case to the extent, but only
to the extent, that any such loss, liability, claim, damage or expense arises
out of or is based upon any untrue statement or alleged untrue statement or
omission or alleged omission made therein in reliance upon and in conformity
with written information relating to the Initial Purchasers furnished to the
Company by the Initial Purchasers expressly for use therein. The Company and the
Initial Purchasers acknowledge that the information set forth in Section 9 is
the only information furnished in writing by the Initial Purchasers to the
Company expressly for use in the Offering Memorandum.

                  (c) Promptly after receipt by an indemnified party under
subsection (a) or (b) above of notice of the commencement of any action, suit or
proceeding (collectively, an "action"), such indemnified party shall, if a claim
in respect thereof is to be made against the indemnifying party under such
subsection, notify each party against whom indemnification is to be sought in
writing of the commencement of such action (but the failure so to notify an
indemnifying party shall not relieve such indemnifying party from any liability
that it may have under this Section 6 except to the extent that it has been
prejudiced in any material respect by such failure or from any liability which
it may otherwise have). In case any such action is brought against any
indemnified party, and it notifies an indemnifying party of the commencement of
such action, the indemnifying party will be entitled to participate in such
action, and to the extent it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense of such action with counsel
satisfactory to such indemnified party. Notwithstanding the foregoing, the
indemnified party or parties shall have the right to employ its or their 
   26
                                      -26-


own counsel in any such action, but the fees and expenses of such counsel shall
be at the expense of such indemnified party or parties unless (i) the employment
of such counsel shall have been authorized in writing by the indemnifying
parties in connection with the defense of such action, (ii) the indemnifying
parties shall not have employed counsel to take charge of the defense of such
action within a reasonable time after notice of commencement of the action, or
(iii) such indemnified party or parties shall have reasonably concluded that
there may be defenses available to it or them that are different from or
additional to those available to one or all of the indemnifying parties (in
which case the indemnifying parties shall not have the right to direct the
defense of such action on behalf of the indemnified party or parties), in any of
which events such reasonable fees and expenses of counsel shall be borne by the
indemnifying parties. In no event shall the indemnifying party be liable for the
fees and expenses of more than one counsel (together with appropriate local
counsel) at any time for all indemnified parties in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances.
Anything in this subsection to the contrary notwithstanding, an indemnifying
party shall not be liable for any settlement of any claim or action effected
without its written consent; provided, however, that such consent was not
unreasonably withheld.

                  7. CONTRIBUTION. In order to provide for contribution in
circumstances in which the indemnification provided for in Section 6 of this
Agreement is for any reason held to be unavailable from the indemnifying party,
or is insufficient to hold harmless a party indemnified under Section 6 of this
Agreement, the Company, the Subsidiary Guarantors and the Initial Purchasers
shall contribute to the aggregate losses, claims, damages, liabilities and
expenses of the nature contemplated by such indemnification provision (including
any reasonable investigation, legal and other expenses incurred in connection
with, and any amount paid in settlement of, any action or any claims asserted)
to which the Company and the Initial Purchasers may be subject in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Subsidiary Guarantors, on the one hand, and the Initial
Purchasers, on the other hand, from the offering of the Senior Notes or, if such
allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to above but also
the relative fault of the Company and the Subsidiary Guarantors, on the one
hand, and the Initial Purchasers, on the other hand, in connec-
   27
                                      -27-


tion with the statements or omissions that resulted in such losses, claims,
damages, liabilities or expenses, as well as any other relevant equitable
considerations. The relative benefits received by the Company and the Subsidiary
Guarantors, on the one hand, and the Initial Purchasers, on the other hand,
shall be deemed to be in the same proportion as (x) the total proceeds from the
offering of Senior Notes (net of discounts and commissions but before deducting
expenses) received by the Company and the Subsidiary Guarantors and (y) the
total discounts and commissions received by the Initial Purchasers as set forth
in the table on the cover page of the Offering Memorandum. The relative fault of
the Company and the Subsidiary Guarantors, on the one hand, and the Initial
Purchasers, on the other hand, shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Initial Purchasers and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission or alleged statement or omission.

                  The Company, the Subsidiary Guarantors and the Initial
Purchasers agree that it would not be just and equitable if contribution
pursuant to this Section 7 were determined by pro rata allocation or by any
other method of allocation that does not take into account the equitable
considerations referred to above. Notwithstanding the provisions of this Section
7, (i) in no case shall the Initial Purchasers be required to contribute any
amount in excess of the amount by which the total discount and commissions
applicable to the Senior Notes pursuant to this Agreement exceeds the amount of
any damages that the Initial Purchasers have otherwise been required to pay by
reason of any untrue or alleged untrue statement or omission or alleged omission
and (ii) no person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Act) shall be entitled to contribution from any person who
was not guilty of such fraudulent misrepresentation. For purposes of this
Section 7, each person, if any, who controls the Initial Purchasers within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act shall have
the same rights to contribution as the Initial Purchasers, and each person, if
any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act shall have the same rights to contribution as
the Company, subject in each case to clauses (i) and (ii) of this Section 7. Any
party entitled to contribution will, promptly after receipt of notice of
commencement of any action against such party in respect of 
   28
                                      -28-

which a claim for contribution may be made against another party or parties
under this Section 7, notify such party or parties from whom contribution may be
sought, but the omission to so notify such party or parties shall not relieve
the party or parties from whom contribution may be sought from any obligation it
or they may have under this Section 7 or otherwise; provided, however, that no
additional notice shall be required with respect to any action for which notice
has been given under Section 6 for purposes of indemnification. No party shall
be liable for contribution with respect to any action or claim settled without
its written consent, provided, however, that such written consent was not
unreasonably withheld.

                  8. CONDITIONS OF INITIAL PURCHASERS' OBLIGATIONS. The
obligations of the Initial Purchasers to purchase and pay for the Senior Notes,
as provided for in this Agreement, shall be subject to satisfaction of the
following conditions prior to or concurrently with such purchase:

                  (a) All of the representations and warranties of the Company
         and the Subsidiary Guarantors contained in this Agreement shall be true
         and correct on the date of this Agreement and on the Closing Date. The
         Company and the Subsidiary Guarantors shall have performed or complied
         with all of the agreements contained in this Agreement and required to
         be performed or complied with by then at or prior to the Closing Date.

                  (b) No stop order suspending the qualification or exemption
         from qualification of the Senior Notes in any jurisdiction shall have
         been issued and no proceeding for that purpose shall have been
         commenced or shall be pending or threatened.

                  (c) No action shall have been taken and no statute, rule,
         regulation or order shall have been enacted, adopted or issued by any
         governmental agency that would, as of the Closing Date, prevent the
         issuance of the Senior Notes or the Exchange Offer; no action, suit or
         proceeding shall have been commenced and be pending against or
         affecting or, to the best knowledge of the Company and the Subsidiary
         Guarantors, threatened against the Company and/or the Subsidiary
         Guarantors before any court or arbitrator or any governmental body,
         agency or official that, if adversely determined, would result in a
         Material Adverse Effect.
   29
                                      -29-


                  (d) Since February 28, 1997, except as contemplated by the
         Offering Memorandum, neither the Company nor any of the Subsidiary
         Guarantors had any material liabilities or obligations, direct or
         contingent, that were not set forth in the Company's consolidated
