     The Final Memorandum, at the date hereof, does not contain any untrue
     statement of a material fact or omit to state any material fact necessary

     representation or warranty is made as to the information contained in or
     omitted from the Preliminary Memorandum or the Final Memorandum, or any
     amendment or supplement thereto, in reliance upon and in conformity with
     information furnished in writing to the Company and Holding by or on behalf
     of the Purchasers specifically for inclusion therein, it being understood
     that the only such information is that described in Section 8(b) hereof.

          (b)  Neither the Company nor Holding has taken nor will take, directly
     or indirectly, any action prohibited by Regulation M under the Exchange Act
     of 1934, as amended (the "Exchange Act"), in connection with the offering
     of the Securities.

          (c)  None of the Company, Holding, any of their respective Affiliates
     (as defined in Rule 501(b) of Regulation D under the Securities Act
     ("Regulation D")), or any person acting on their behalf, has (i) sold,
     offered for sale, solicited offers to buy or otherwise negotiated in

     any form of general solicitation or general advertising (within the meaning
     of Regulation D) in connection with any offer or sale of the Securities in
     the United States.

 
                                                                               4

     given to them by Regulation S.

          (f)  Neither Holding nor the Company is an "investment company" within
     the meaning of the Investment Company Act of 1940, as amended (the

     respective jurisdictions of organization, with full corporate power and
     authority to own or lease, as the case may be, their properties and conduct
     their business as described in the Final Memorandum, and are duly qualified
     to do business as foreign corporations and are in good standing under the
     laws of all jurisdictions in which their ownership or lease of property or
     the conduct of their business requires such qualification except where the
     failure to be so qualified would not, individually or in the aggregate,
     have a Material Adverse Effect (as defined below). Each of the Company and
     Holding has full corporate power and authority to enter into this
     Agreement, the Registration Agreement, the Amended and Restated Merger

     Agreement, the New Credit Facility, the Indenture and the Exchange
     Indenture have been duly authorized by the Company and Holding and, when
     duly executed and delivered by the parties thereto (assuming the due

     Indenture by the Trustee), each of the Merger Agreement, the New Credit
     Facility, the Indenture and the Exchange Indenture will constitute a valid

     claims and encumbrances under the New Credit Facility.

          (i)  (i) The Notes have been duly and validly authorized for issuance
     and sale by the Company to the Purchasers, and upon execution and delivery
     of the Indenture, and when the Notes are issued, authenticated and
     delivered in accordance with the Indenture and paid for in accordance with
     the terms of this Agreement, the Notes will constitute valid and binding
     obligations of the Company and Holding enforceable against the Company and
     Holding in accordance with their terms and entitled

     insolvency, fraudulent conveyance, reorganization, moratorium and similar
     laws affecting creditors' rights and remedies generally and to general
     principles of equity (regardless of whether enforcement is sought in a

               (ii)   The Holding Preferred Stock has been duly and validly
          authorized for issuance and sale by Holding to the Purchasers, and

          issuance of the Holding Preferred Stock is not subject to preemptive
          or other similar rights.

               (iii)  The Company Preferred Stock has been duly and validly
          authorized for issuance in exchange for the Holding Preferred Stock by
          the Company; and when the Company Preferred Stock, if issued, is
          delivered by the Company in exchange for the Holding Preferred Stock,
          such Company Preferred Stock will be validly issued, fully paid and
          nonassessable; and the issuance of the Company Preferred Stock will
          not be subject to preemptive or other similar rights.

               (iv)   The Company Exchange Debentures have been duly authorized
          for issuance in exchange for Holding Preferred Stock by the Company;
          and upon execution and delivery of the Exchange Indenture, and, when
          the Company Exchange Debentures are issued and authenticated in
          accordance with the Exchange Indenture and delivered in exchange for
          the Holding Preferred Stock, the Company Exchange Debentures will
          constitute valid and binding obligations of the Company enforceable
          against the Company in accordance with their terms and entitled to the
          benefits of the Exchange Indenture, subject to applicable bankruptcy,
          insolvency, reorganization, fraudulent transfer, moratorium, and
          similar laws affecting creditors' rights and remedies generally and to
          general principles of equity (regardless of whether enforcement is
          sought in a proceeding at law or in equity) and Sections 500 et seq.
          of the Code.

 
                                                                               7

          (j)  The Securities conform, in all material respects, to the
     description thereof contained in the Preliminary Memorandum and Final
     Memorandum.

          (k)  The execution, delivery and performance of this Agreement, the
     Registration Agreement, the Merger Agreement, the New Credit Facility, the
     Indenture, the Exchange Indenture, the Notes, the Holding Preferred Stock,
     the Company Exchange Debentures and the Company Preferred Stock by the
     Company and Holding, as applicable, and the consummation of the
     Transactions, will not conflict with or result in a breach or violation of
     any of the terms and provisions of, or constitute a default under, (i) the
     articles of incorporation, by-laws or other organizational documents of the
     Company, Holding or the Subsidiary, (ii) any material statute, rule or
     regulation applicable to the Company, Holding or the Subsidiary (other than
     California Corporations Code Sections 500 et seq.) or any order of any
     governmental agency or body or any court having jurisdiction over the
     Company, Holding or the Subsidiary or any of their respective properties,
     (iii) any agreement or instrument relating to borrowed money to which the
     Company, Holding or the Subsidiary is a party or by which the Company,
     Holding or the Subsidiary is bound or to which any of their respective
     properties is subject or (iv) any other material agreement or instrument to
     which the Company, Holding or the Subsidiary is a party or by which the
     Company, Holding or the Subsidiary is bound or to which any of their
     respective properties is subject, except in the cases of clauses (iii) or
     (iv) for conflicts, breaches, violations or defaults which would not
     reasonably be expected to have a Material Adverse Effect.  Assuming the
     Securities are sold as described in this Agreement, no consent, approval,
     authorization or other order of any court, regulatory body, administrative
     agency or other governmental body which has not already been obtained is
     required for the execution and delivery of this Agreement, the Registration
     Agreement, the Merger Agreement, the New Credit Facility, the Indenture or
     the Securities or for the consummation of the Transactions, except for

     knowledge, is threatened to be made a party or of which property owned or
     leased by the Company, Holding or the Subsidiary is or, to the best of
     Holding's or the Company's knowledge, is threatened to be made the subject,
     which actions, suits or proceedings could, individually or in the
     aggregate, have a material adverse effect on the condition (financial or
     otherwise), properties, business, results of operations or prospects of
     Holding, the Company and their Subsidiaries, taken as a whole, or
     materially and adversely affect the ability of the Company and Holding to
     perform their respective obligations under this Agreement, the Registration
     Agreement, the Merger Agreement, the New Credit Facility, the Indenture or
     the Securities or to consummate the Transactions (a "Material Adverse
     Effect"), and (ii) no labor disturbance by the employees of Holding, the
     Company, or the Subsidiary exists or, to the best of Holding's or the
     Company's knowledge is imminent, in either case which could have a Material

     Subsidiaries is a party or subject to the provisions of any material
     injunction, judgment, decree or order of any court, regulatory body,
     administrative agency or other governmental body.

          (m)  Neither Holding nor the Company has paid or agreed to pay to any
     person any compensation for soliciting another to purchase any securities

     Agreement between the Company and the lenders named therein dated April 28,
     1995, as amended (the "1995 Credit Agreement"), will be permanently
     satisfied and discharged and the 1995 Credit Agreement will be terminated.

 
                                                                               9

          (o)  The Company and the Subsidiary are conducting business in
     compliance with all applicable laws, rules and regulations of the
     jurisdictions in which they are conducting business, including, without
     limitation, the Food, Drug and Cosmetic Act (the "FDC Act") and the
     regulations of the Food and Drug Administration ("FDA") and all applicable
     environmental laws and regulations, except where the failure to be so in
     compliance would not have a Material Adverse Effect.

          (p)  Neither Holding, the Company nor the Subsidiary (i) is in
     violation of its charter, by-laws or other constituent documents or (ii) is
     in default in any material respect, and no event has occurred which, with
     notice or lapse of time or both, would constitute such default, in the due
     performance or observance of any term, covenant or condition contained in
     any material indenture, mortgage, deed of trust, loan agreement or other
     material agreement or instrument to which it is a party or by which it is
     bound or to which any of its properties or assets is subject which
     violation or default would cause a Material Adverse Effect.

          (q)  There are no defects in title to the owned properties or
     encumbrances upon the leased properties of the Company and the Subsidiary
     or the assets or facilities used by the Company and the Subsidiary, except
     any such defects that are in the ordinary course of business of the Company
     or such Subsidiary which, individually or in the aggregate, have a Material
     Adverse Effect.

          (r)  Each of the Company and its Subsidiaries owns or possesses
     adequate rights to use all material patents, patent applications,
     trademarks, service marks, trade names, trademark registrations, service
     mark registrations, copyrights, licenses and know-how (including trade
     secrets and other unpatented and/or unpatentable proprietary or
     confidential information, systems or procedures) necessary for the conduct
     of its business, except where the failure to own or possess such rights
     would not have a Material Adverse Effect, and has no reason to believe that
     the conduct of its business will conflict with any such rights of others
     which is reasonably likely to have a Material Adverse Effect, and has not
     received any notice of any claim of 

 
                                                                              10

     a Material Adverse Effect.

          (s)  (i)  The consolidated financial statements with respect to
     Holding and the Company included in the Final Memorandum present fairly the
     consolidated financial position of Holding, and its consolidated
     Subsidiaries and the Company and its consolidated Subsidiary, as
     applicable, as of the dates shown and their results of operations and cash
     flows for the periods shown, and such consolidated financial statements
     have been prepared in conformity with the generally accepted accounting
     principles in the United States applied on a consistent basis.

          (ii) The pro forma financial statements of Holding and the Company
     included in the Final Memorandum are based upon reasonable assumptions for
     presenting the significant effects of the Transactions, give appropriate
     effect to those assumptions, and reflect the proper application of those
     adjustments to the historical consolidated financial statement amounts in
     the consolidated financial statements of Holding and the Company, as
     applicable.  Such pro forma financial statements comply in form in all
     material respects with the applicable accounting requirements of the
     Exchange Act and the related published rules and regulations that would
     apply to the Final Memorandum if the Final Memorandum were a prospectus
     included in a registration statement on Form S-1 under the Securities Act.

          (t)  On the Closing Date (after giving effect to the issuance of the
     Notes and the Holding Preferred Stock and the consummation of the
     Transactions) each of Holding and the Company will be Solvent.  As used in
     this paragraph, the term "Solvent" means, with respect to a particular
                               -------                                     
     date, that on such date (i) the aggregate fair value or present fair
     salable value of the assets of Holding and the Company, as applicable, is
     not less than its total existing debts and liabilities (including
     identified contingent liabilities) as they become absolute and matured in
     the normal course of business, (ii) Holding and the Company are able to pay
     their debts and other liabilities, contingent obligations and commitments
     as they mature and become due in the normal course of business and (iii)
     Holding and the Company do not have an 

 
                                                                              11

     unreasonably small amount of capital with which to conduct their business.
     In computing the amount of such contingent liabilities at any time, it is
     intended that such liabilities will be computed at the amount that, in
     light of all the facts and circumstances existing at such time, represents
     the amount that can reasonably be expected to become an actual or matured
     liability.

          (u)  Since the date of the latest audited consolidated financial
     statements of the Company and Holding included in the Final Memorandum,
     there has been no material adverse change, nor to the Company's and
     Holding's knowledge any development or event involving a prospective
     material adverse change, in the condition (financial or other), business,
     properties or results of operations of Holding, the Company and their
     Subsidiaries taken as a whole, and, except as disclosed in the Final
     Memorandum, since the date of the latest audited consolidated financial
     statements of the Company and Holding included in the Final Memorandum,
     there has been no dividend or distribution of any kind declared, paid or
     made by the Company or Holding on any class of its capital stock.

          (v)  Assuming the accuracy of the representations and warranties
     contained in Section 4, it is not necessary in connection with the offer,
     sale and delivery of the Notes and Preferred Stock in the manner

     process all date information prior to and after December 31, 1999

     arising from the inability of computer hardware and software to recognize
     and properly execute date sensitive function involving certain dates prior
     to and any dates after December 31, 1999 (the "Year 2000 Problem") which
     could reasonably be expected to result in a Material Adverse Effect.

Holding that:

          (a)  It has not offered or sold, and will not offer or sell, any
     Securities except (i) to those it reasonably believes to be qualified
     institutional buyers (as defined in Rule 144A under the Securities Act) and
     that, in connection with each such sale, it has taken or will take
     reasonable steps to ensure that the purchaser of such Securities is aware

     the Registration Agreement.

 
                                                                              14

          5.  Agreements.  The Company and Holding jointly and severally agree
              -----------

     other production of all documents relating to the offerings.

          (b)  Neither the Company nor Holding will amend or supplement the
     Final Memorandum without the prior consent of the Purchasers.

          (c)  If at any time prior to the completion of the sale of the
     Securities by the Purchasers, any event occurs as a result of which the
     Final Memorandum, as then amended or supplemented, would 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, or if it shall be necessary to amend
     or supplement the Final Memorandum to comply with the Exchange Act or the

     will notify the Purchasers of the same and, subject to paragraph (b) of
     this Section 5, will prepare and provide to the Purchasers pursuant to
     paragraph (a) of this Section 5 an amendment or supplement which will
     correct such statement or omission or effect such compliance.

          (d)  The Company and Holding will arrange for the qualification of the
     Securities for sale under the laws of such U.S. jurisdictions as the
     Purchasers may designate and will maintain such qualifications in effect so
     long as required for the sale of the Securities provided that Company and
     Holding will not be obligated to qualify as foreign corporations or to
     execute a general consent to service of process in any jurisdiction or to
     take any other action that would subject them to general service of process
     or taxation in any jurisdiction in which they are not otherwise subject.
     The Company and Holding will promptly advise the Purchasers of the receipt
     by them of any notification with respect to the suspension of the

     by any of them.

          (f)  None of the Company, Holding, nor any of their respective
     Affiliates, or any person acting on their behalf will, directly or
     indirectly, make offers or sales of any security, or solicit offers to buy
     any security, under circumstances that would require the registration of
     the Securities under the Securities Act.

          (g)  None of the Company, Holding nor any of their respective
     Affiliates or any person acting on their behalf will engage in any form of
     general solicitation or general advertising (within the meaning of
     Regulation D) in connection with any offer or sale of the Securities in the
     United States, except pursuant to a registered public offering, whether an
     exchange offer or shelf registration, as provided in the Registration
     Agreement.

          (h)  So long as any of the Securities are "restricted securities"
     within the meaning of Rule 144(a)(3) under the Securities Act, the Company
     and Holding will, during any period in which it is not subject to and in
     compliance with Section 13 or 15(d) of the Exchange Act, provide to each
     holder of such restricted securities and to each prospective purchaser (as
     designated by such holder) of such restricted securities, upon the request
     of such holder or prospective purchaser, any information required to be
     provided by Rule 144A(d)(4) under the Securities Act. The information
     provided pursuant hereto will not, at the date thereof, contain 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.  This covenant is intended to be for
     the benefit of the holders, and the prospective purchasers 

 
                                                                              16

     securities.

     efforts with respect to the Securities except pursuant to a registered
     public offering as provided in the Registration Agreement and each of them
     will comply with the offering restrictions requirement of Regulation S.

     be designated Portal eligible securities, will pay the requisite fees
     related thereto and have been advised by The Portal Market that the
     Securities have or will be designated Portal eligible securities in
     accordance with the rules and regulations of the National Association of
     Securities Dealers, Inc.

     indirectly, any action prohibited by Regulation M under the Exchange Act,
     in connection with the offering of the Securities.

          (m)  Neither Holding nor the Company will, until 90 days following the
     Closing Date, without the prior written consent of Salomon Brothers Inc,
     offer, sell or contract to sell, or otherwise dispose of, directly or
     indirectly, or announce the offering of, or file a registration statement
     for, any debt securities or capital stock which is preferred as to payment
     of dividends, or as to distribution upon liquidation, over any other class
     of capital stock issued or guaranteed by Holding or the Company ("preferred
     stock") (other than (i) the Securities and (ii) pursuant to a registered
     public offering as provided in the Registration Agreement).

          (n)  Holding and The Company will apply the net proceeds from the sale
     of the Securities sold by them 

 
                                                                              17

     substantially in accordance with the statements under the caption "Use of
     Proceeds" in the Final Memorandum.

     the Mirror Preferred Stock in the form previously agreed to by the
     Purchasers.  The Company will not agree to any modification in the economic
     or other material terms of such certificate of amendment without the
     consent of a majority of holders of the Holding Preferred Stock.

          (p)  In the event that the Merger has not been consummated within

          registration of the Securities under the Securities Act is required,
          and no qualification of the Indenture or the Exchange Indenture under
          the Trust Indenture Act is necessary, for the offer, sale and delivery
          of the Securities in the manner contemplated by this Agreement; and

               (xvii) neither Holding nor the Company is an "investment company"
          within the meaning of the Investment Company Act of 1940, as amended
          (the "Investment Company Act"), without taking account of any
          exemption arising out of the number of holders of the Company's or
          Holding's securities.

          Such counsel shall also state that such counsel has participated in
     conferences with officers and other representatives of the Company and
     Holding, representatives of the independent public accountants for the
     Company and Holding and representatives of the Initial Purchasers at which
     the contents of the Final Memorandum and related matters were discussed.
     Such counsel shall state that although such counsel has made no independent
     check or verification of the accuracy, completeness or fairness of the
     statements made in the Final Memorandum (except as set forth in paragraphs
     (ii), (iii), (xi), (xii), (xiii) and (xiv) above) on the basis of the
     foregoing (relying as to materiality to a large extent upon the statements
     of officers and other representatives of the Company and Holding) no facts
     have come to such counsel's attention that have caused such counsel to
     believe that the Final Memorandum as of its date and as of the Closing Date
     contained or contains an untrue statement of a material fact or omitted or
     omits to state a material fact necessary in order to make the statements
     therein, in light of the circumstances under which they were made, not
     misleading (it being understood that such counsel need express no opinion
     on the financial statements or 

 
                                                                              23

     other financial and statistical data included in the Final Memorandum).

          In rendering such opinion, such counsel may rely (A) as to matters
     involving the application of laws of any jurisdiction other than the State
     of California and the federal laws of the United States to the extent they
     deem proper and specified in such opinion, upon the opinion of other
     counsel of good standing whom they believe to be reliable and who are
     satisfactory to counsel for the purchasers and (B) as to matters of fact,
     to the extent they deem proper, on certificates of responsible officers of
     Holding and the Company and public officials, copies of which shall be
     provided to the Purchasers.

          Such counsel may deliver the opinions relating to the Merger Agreement
     and the New Credit Facility set forth in paragraphs 6(vii), 6(viii), 6(ix)
     and 6(x) above by delivering letters dated the Closing Date permitting the
     Purchasers to rely upon separate opinion letters dated the Closing Date
     rendered to the parties to the Merger Agreement and the New Credit Facility
     and containing substantially similar opinions.

          All references in this Section 6(a) to the Final Memorandum shall be
     deemed to include any amendment or supplement thereto at the Closing Date.

          (b)  The Company and Holding shall have caused Hyman, Phelps &
     McNamara, P.C., special regulatory counsel for the Company and Holding, to
     have furnished to the Purchasers their opinion dated the Closing Date and
     addressed to the Purchasers, to the effect that the information and
     disclosure contained in the Final Memorandum under the headings "Risk
     Factors--Government Regulation" and "Business--Government Regulation and
     Environmental Matters", is accurate and complete in all material respects,
     insofar as such information and disclosure relate to Food and Drug
     Administration law, legal matters and compliance requirements.

          Such counsel shall also state that, with respect to the other
     information and disclosure contained in the Final Memorandum not specified
     above, they have no reason to believe that at the Execution Time the Final
     Memorandum contained an untrue statement of a material 

 
                                                                              24

     fact or omitted to state a material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading or that the Final Memorandum includes an untrue
     statement of a material fact or omits to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading.

          All references in this Section 6(b) to the Final Memorandum shall be
     deemed to include any amendment or supplement thereto at the Closing Date.

          (c)  The Purchasers shall have received from Cravath, Swaine & Moore
     such opinion or opinions, dated the Closing Date, with respect to the
     issuance and sale of the Securities, the Final Memorandum (as amended or
     supplemented at the Closing Date) and other related matters as the
     Purchasers may reasonably require, and the Company and Holding shall have
     furnished to such counsel such documents as they request for the purpose of
     enabling them to pass upon such matters.

          (d)  The Company and Holding shall have furnished to the Purchasers
     certificates of the Company and of Holding, signed by the President and
     Chief Financial Officer of the Company and the President or Vice President
     and an Assistant Secretary of Holding, dated the Closing Date, to the
     effect that the signers of such certificate have examined the Final
     Memorandum, any amendment or supplement to the Final Memorandum and this
     Agreement and the Registration Agreement and that:

               (i)   the representations and warranties of the Company and of
          Holding in this Agreement and the Registration Agreement are true and
          correct in all material respects on and as of the Closing Date with
          the same effect as if made on the Closing Date, and the Company and
          Holding have complied in all material respects with all the agreements
          and satisfied all the conditions on their part to be performed or
          satisfied hereunder or thereunder at or prior to the Closing Date; and

               (ii)  since the date of the most recent financial statements
          included in the Final Memorandum, there has been no material adverse

 
                                                                              25

          change in the condition (financial or otherwise), properties,
          business, results of operations or prospects of the Company, Holding
          or any of their respective Subsidiaries, taken as a whole, whether or
          not arising from transactions in the ordinary course of business,
          except as disclosed in the Final Memorandum (exclusive of any
          amendment or supplement thereto).

          (e)  At the Execution Time and at the Closing Date, the Holding and
     Company shall have caused Arthur Andersen LLP to have furnished to the
     Purchasers a letter or letters, dated respectively as of the Execution Time
     and as of the Closing Date, in form and substance satisfactory to the
     Purchasers, confirming that they are independent accountants within the
     meaning of the Securities Act and the Exchange Act and the applicable rules
     and regulations thereunder and Rule 101 of the Code of Professional Conduct
     of the American Institute of Certified Public Accountants (the "AICPA") and
     stating in effect that:

               (i)  in their opinion the audited financial statements of Holding
          and the Company and the audited pro forma financial statements of the
          Company included in the Final Memorandum and reported on by them, and
          the unaudited pro forma financial statements of Holding included in
          the Final Memorandum, comply in form in all material respects with the
          applicable accounting requirements of the Exchange Act and the related
          published rules and regulations that would apply to the Final
          Memorandum if the Final Memorandum were a prospectus included in a
          registration statement on Form S-1 under the Securities Act;

               (ii) on the basis of a reading of the unaudited pro forma
          financial statements of Holding included in the Final Memorandum;
          carrying out certain specified procedures; inquiries of certain
          officials of Holding and the Company who have responsibility for
          financial and accounting matters; and proving the arithmetic accuracy
          of the application of the pro forma adjustments to the historical
          amounts in such unaudited pro forma financial statements, nothing came
          to their attention which causes them to believe that the 

 
                                                                              26

          pro forma adjustments have not been properly applied to the historical
          amounts in the compilation of such statements.

               (iii) based upon the procedures detailed in such letter with
          respect to the period subsequent to the date of the latest audited
          financial statements included in the Final Memorandum, including the
          reading of the minutes and inquiries of certain officials of Holding
          and of the Company who have responsibility for the financial and
          accounting matters and certain other limited procedures requested by
          the Purchasers and described in detail in such letter, nothing has
          come to their attention that causes them to believe that:

                     (A) with respect to the period subsequent to December 26,
               1997, there were any changes, at a specified date not more than
               five business days prior to the date of the letter, in the total
               debt of Holding, the Company and any of their Subsidiaries or
               capital stock of Holding or the Company or decreases in the
               stockholders' equity of Holding or the Company or decreases in
               working capital of Holding, the Company, and any of their
               Subsidiaries, as compared with the amounts shown on the December
               26, 1997 consolidated balance sheet included in the Final
               Memorandum, or for the period from December 26, 1997, to such
               specified date there were any decreases, as compared with the
               corresponding period in the preceding year in total revenues, net
               income before income taxes, net income or EBITDA, as defined in
               the Indenture, except in all instances for changes or decreases
               set forth in such letter, in which case the letter shall be
               accompanied by an explanation by Holding or the Company, as the
               case may be, as to the significance thereof unless said
               explanation is not deemed necessary by the Purchasers; or

                    (B) the information included under the heading "Selected
               Historical Financial Data" 

 
                                                                              27

               is not in conformity with the disclosure requirements of
               Regulation S-K that would apply to the Final Memorandum if the
               Final Memorandum were a prospectus included in a registration
               statement on Form S-1 under the Securities Act; and

               (iii) they have performed certain other specified procedures as a
          result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of Holding, the Company or any of their
          Subsidiaries) set forth in the Final Memorandum, including the
          information set forth under the captions "Summary", "Risk Factors",
          "Use of Proceeds", "Capitalization" "Selected Historical Financial
          Data", "Management's Discussion and Analysis of Financial Condition
          and Results of Operations", "Business", "Management", "Description of
          Senior Credit Facility" and "Description of the Notes" in the Final
          Memorandum, agrees with the accounting records of Holding, the
          Company, or any of their Subsidiaries, excluding any questions of
          legal interpretation.
 
          All references in this Section 6(e) to the Final Memorandum shall be
     deemed to include any amendment or supplement thereto at the date of the
     letter.

          (f)  Subsequent to the Execution Time or, if earlier, the dates as of
     which information is given in the Final Memorandum, there shall not have
     been (i) any change or decrease specified in the letter or letters referred
     to in paragraph (e)(iii)(A)of this Section 6 or (ii) any change, or any
     development involving a prospective change, in or affecting the business or
     properties of the Company, Holding or any of their respective Subsidiaries
     the effect of which, in any case referred to in clause (i) or (ii) above,
     is not disclosed in the Final Memorandum and is, in the judgment of the
     Purchasers, so material and adverse as to make it impractical or
     inadvisable to market the Securities as contemplated by the Final
     Memorandum.

 
                                                                              28

          (g)  Subsequent to the Execution Time, there shall not have been (i)
     any decrease in the rating of any of the Securities or any other debt
     securities or preferred stock of the Company or Holding by any "nationally
     recognized statistical rating organization" (as defined for purposes of
     Rule 436(g) under the Securities Act) or (ii) any notice given of any
     intended or potential decrease in any such rating or that such organization
     has under surveillance or review (other than any such notice with positive
     implications of a possible upgrading) its rating of any of the Securities
     or any other debt securities or preferred stock of the Company or Holding.

          (h)  On or prior to the Closing Date, the Registration Agreement shall
     have been executed substantially in the form hereto delivered to you and
     shall have been delivered to you and the Trustee.

          (i)  Each of the New Credit Facility and the Merger Agreement shall
     have been executed and delivered by the parties thereto. The terms of the
     New Credit Facility and the Merger Agreement shall be reasonably
     satisfactory to the Purchasers, and the Purchasers shall have received
     executed copies of the New Credit Facility and the Merger Agreement and all
     other documents and agreements entered into and received in connection
     therewith certified by the Secretary of the Company as being true, complete
     and correct. There shall exist at and as of the Closing Date (after giving
     effect to the Transactions) no condition that would constitute a default
     (or an event that with notice or lapse of time, or both, would constitute a
     default) under the New Credit Facility.

          (j)  The Purchasers shall have received evidence, reasonably
     satisfactory to them, that (A) the merger of River Acquisition Corp. with
     and into the Company shall have been consummated in accordance with the
     terms of the Merger Agreement, (B) the initial funding shall have occurred
     under the New Credit Facility, (C) Freeman Spogli & Co. and certain members
     of the Company's management shall have made a $61.5 million equity
     investment in Holding and (D) the Company shall have issued shares of its
     11 1/2% Senior PIK Preferred Stock due 2010 ("Mirror Preferred Stock")
     having an aggregate liquidation preference of $30.0 million to Holding on
     the terms described in the Final Memorandum 

 
                                                                              29

     and otherwise reasonably satisfactory to the Purchasers. Notwithstanding
     the foregoing, the condition set forth in clause (A) above shall be deemed
     to have been satisfied if the Purchasers have not received evidence of the
     consummation of the Merger solely as a result of differences in time zones
     in connection with the processing of the certificate of merger relating to
     the Merger by the Secretary of State of the State of California.

          (k)  Prior to the Closing Date, the Company and Holding shall have
     furnished to the Purchasers such further information, certificates and
     documents as the Purchasers may reasonably request.

          If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Purchasers and Counsel for the Purchasers, this Agreement
and all obligations of the Purchasers hereunder may be canceled at, or at any
time prior to, the Closing Date by the Purchasers.  Notice of such cancelation
shall be given to the Company and to Holding in writing or by telephone
confirmed in writing.

          The documents required to be delivered by this Section 6 will be
delivered at the office of Counsel for the Purchasers, 825 Eighth Avenue, New
York, New York, on the Closing Date.

          7.  Reimbursement of Expenses.  If the sale of the Securities provided
              --------------------------                                        
for herein is not consummated because any condition to the obligations of the
Purchasers set forth in Section 6 hereof is not satisfied or because of any
refusal, inability or failure on the part of the Company or Holding to perform
any agreement herein or comply with any provision hereof, in each case other
than by reason of a default by the Purchasers, the Company or Holding will
reimburse the Purchasers upon demand for all reasonable out-of-pocket expenses
(including reasonable fees and disbursements of counsel) that shall have been
incurred by them in connection with the proposed purchase and sale of the
Securities.

 
                                                                              30

          8.  Indemnification and Contribution.  (a)  The Company and Holding
              ---------------------------------                              
agree, jointly and severally, to indemnify and hold harmless each Purchaser,
each director, officer, employee and agent of any Purchaser and each other
person, if any, who controls any Purchaser within the meaning of Section 15 of
the Securities Act or Section 20 of the Exchange Act against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of them
may become subject under the Securities Act, the Exchange Act or other Federal
or state statutory law or regulation, at common law or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of a material fact contained in the Preliminary Memorandum, the Final Memorandum
or any information provided by the Company or Holding to any holder or
prospective purchaser of Securities pursuant to Section 5(h), or in any
amendments thereof or supplements thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, and agrees to
reimburse each such indemnified party, as incurred, for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
                                                             --------  ------- 
that the Company and Holding will not be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of or is based upon
any such untrue statement or alleged untrue statement or omission or alleged
omission made in the Preliminary Memorandum or the Final Memorandum, or in any
amendment thereof or supplement thereto, in reliance upon and in conformity with
written information furnished to the Company or Holding by or on behalf of the
Purchasers specifically for inclusion therein, it being understood that the only
such information is that described in Section 8(b); provided further, however,
                                                    ----------------  ------- 
that the indemnity agreement contained in this Section 8(a) shall not inure to
the benefit of any indemnified party to the extent that it is determined by a
final, non-appealable judgment that (i) the Preliminary Memorandum contained an
untrue statement of a material fact or omitted to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading, (ii) the
sale to the person asserting any such losses, claims, damages or 

 
                                                                              31

liabilities was an initial resale of the Securities by any Purchaser, (iii) any
such loss, claim, damage or liability of such indemnified party results from the
fact that there was not sent or given to such person, at or prior to the written
confirmation of the sale of such Securities to such person, a copy of any
revised Preliminary Memorandum, the Final Memorandum or the Final Memorandum as
amended or supplemented, and the Company had previously furnished copies thereof
to such Purchaser and (iv) the revised Preliminary Memorandum, the Final
Memorandum or the Final Memorandum as amended or supplemented corrected such
untrue statement or omission. This indemnity agreement will be in addition to
any liability that the Company and Holding may otherwise have.

          (b)  Each Purchaser severally and not jointly agrees to indemnify and
hold harmless the Company, Holding, their directors and officers, and each other
person, if any, who controls the Company or Holding within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same
extent as the foregoing indemnity from the Company and Holding to the
Purchasers, but only with reference to written information relating to the
Purchasers furnished to the Company or Holding by or on behalf of the Purchasers
specifically for inclusion in the Preliminary Memorandum or the Final Memorandum
(or in any amendment thereof or supplement thereto).  This indemnity agreement
will be in addition to any liability which the Purchasers may otherwise have.
The Company and Holding acknowledge that the statements set forth in the last
paragraph of the cover page and under the heading "Plan of Distribution" in the
Preliminary Memorandum and the Final Memorandum (or in any amendment or
supplement thereto) constitute the only information furnished in writing by or
on behalf of the Purchasers for inclusion in the Preliminary Memorandum or the
Final Memorandum (or in any amendment thereof or supplement thereto).

          (c)  Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such 

 
                                                                              32

failure results in the forfeiture by the indemnifying party of substantial
rights and defenses and (ii) will not, in any event, relieve the indemnifying
party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraph (a) or (b) above. The
indemnifying party shall be entitled to participate therein, and to the extent
it may wish, to assume the defense thereof with counsel of the indemnifying
party's choice at the indemnifying party's expense to represent the indemnified
party in any action for which indemnification is sought (in which case the
indemnifying party shall not thereafter be responsible for the fees and expenses
of any separate counsel retained by the indemnified party or parties except as
set forth below); provided, however, that such counsel shall be satisfactory to 
                  --------  -------  
the indemnified party. Notwithstanding the indemnifying party's election to
appoint counsel to represent the indemnified party in an action, the indemnified
party shall have the right to employ separate counsel (including local counsel),
and the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel, if (i) the use of counsel chosen by the indemnifying
party to represent the indemnified party would present such counsel with a
conflict of interest, (ii) the actual or potential defendants in, or targets of,
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded that there may be
legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, (iii)
the indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party; provided that the indemnifying party shall not be
responsible for the expenses of more than one separate counsel (in addition to
one local counsel in each relevant jurisdiction) in any one action. An
indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each 

 
                                                                              33

indemnified party from all liability arising out of such claim, action, suit or
proceeding. An indemnified party will not, without the prior written consent of
the indemnifying party, which consent will not be unreasonably withheld, settle
or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder.

          (d)  In the event that the indemnity provided in paragraph (a) or (b)
of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason (other than as provided in paragraph (a)), the
Company, Holding and the Purchasers agree to contribute to the aggregate losses,
claims, damages and liabilities (including legal or other expenses reasonably
incurred in connection with investigating or defending same) (collectively
"Losses") to which the Company, Holding and the Purchasers may be subject in
such proportion as is appropriate to reflect the relative benefits received by
the Company and Holding on the one hand and by the Purchasers on the other from
the offering of the Securities; provided, however, that in no case shall the
                                --------  -------                           
Purchasers be responsible for any amount in excess of the purchase discount or
commission applicable to the Securities purchased by such the Purchasers
hereunder.  If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Company, Holding and the Purchasers shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company and Holding on the
one hand and of the Purchasers on the other in connection with the statements or
omissions which resulted in such Losses as well as any other relevant equitable
considerations.  Benefits received by the Company and Holding shall be deemed to
be equal to the total net proceeds from the offering of the Securities (before
deducting expenses), and benefits received by the Purchasers shall be deemed to
be equal to the total purchase discounts and commissions, in each case as set
forth on the cover page of the Final Memorandum.  Relative fault shall be
determined by reference to whether any alleged untrue statement or omission
relates to information provided by the Company or Holding on the one hand or the
Purchasers on the other.  The Company, Holding and the Purchasers agree that it
would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation which does not take account of the
equitable considerations referred to 

 
                                                                              34

above. Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section 8,
each person who controls a Purchaser within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act and each director, officer,
employee and agent of a Purchaser shall have the same rights to contribution as
such Purchaser, and each person who controls the Company or Holding within the
meaning of either the Securities Act or the Exchange Act and each officer and
director of the Company or Holding shall have the same rights to contribution
as the Company or Holding, subject in each case to the applicable terms and
conditions of this paragraph (d).

          9.  Default by a Purchaser.  If either Purchaser shall fail to
              -----------------------                                   
purchase and pay for any of the Securities agreed to be purchased by such
Purchaser hereunder and such failure to purchase shall constitute a default in
the performance of its or their obligations under this Agreement, the remaining
Purchaser shall be obligated severally to take up and pay for (in the proportion
which the amount of Securities set forth opposite its name in Schedule I hereto
bears to the aggregate amount of Securities set forth opposite the name of the
remaining Purchaser) the Securities that the defaulting Purchaser agreed but
failed to purchase; provided, however, that in the event that the aggregate
                    --------  -------                                      
amount of Securities that the defaulting Purchaser agreed but failed to purchase
shall exceed 10% of the aggregate principal amount of Securities set forth in
Schedule I hereto, the remaining Purchaser shall have the right to purchase all,
but shall not be under any obligation to purchase any, of the Securities, and if
the non-defaulting Purchaser does not purchase all the Securities, this
Agreement will terminate without liability to the non-defaulting Purchaser, the
Company or Holding.  In the event of a default by either Purchaser as set forth
in this Section 9, the Closing Date shall be postponed for such period, not
exceeding seven days, as the Purchasers shall determine in order that the
required changes in the Final Memorandum or in any other documents or
arrangements may be effected.  Nothing contained in this Agreement shall relieve
any defaulting Purchaser of its liability, if any, to the Company, Holding or
the non-defaulting Purchaser for damages occasioned by its default hereunder.

 
                                                                              35

          10.  Termination.  This Agreement shall be subject to termination in
               ------------                                                   
the absolute discretion of the Purchasers, by notice given to the Company and to
Holding prior to delivery of and payment for the Securities, if prior to such
time (i) trading in securities generally on the New York Stock Exchange shall
have been suspended or limited or minimum prices shall have been established on
such Exchange, (ii) a banking moratorium shall have been declared either by
Federal or New York State authorities or (iii) there shall have occurred any
outbreak or escalation of hostilities, declaration by the United States of a
national emergency or war or other calamity or crisis the effect of which on
financial markets of the United States is such as to make it, in the judgment of
the Purchasers, impracticable or inadvisable to proceed with the offering or
delivery of the Securities as contemplated by the Final Memorandum.

          11.  Representations and Indemnities to Survive. The respective
               -------------------------------------------               
agreements, representations, warranties, indemnities and other statements of the
Company, Holding or their respective officers and of the Purchasers set forth in
this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of the Purchasers, the Company, Holding or
any of the officers, directors or controlling persons referred to in Section 8
hereof, and will survive delivery of and payment for the Securities.  The
provisions of Sections 7 and 8 hereof shall survive the termination or
cancelation of this Agreement.

          12.  Notices.  All communications hereunder will be in writing and
               --------

          13.  Successors.  This Agreement will inure to the benefit of and be
               -----------                                                    
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 8 hereof, and,
except as expressly set forth in Section 5(h) hereof, no other person will have
any right or obligation hereunder.

          14.  APPLICABLE LAW.  THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED
               ---------------                                                  
IN ACCORDANCE WITH THE LAWS OF THE 

 
                                                                              36

STATE OF NEW YORK (WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS THEREOF).

          15.  Business Day.  For purposes of this Agreement, "business day"
               -------------                                                
means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on

obligated by law, executive order or regulation to close.

          16.  Counterparts.  This Agreement may be executed in one or more
               -------------                                               
counterparts, each of which will be deemed to be an original, but all such
counterparts will together constitute one and the same instrument.

 
                                                                              37
