ITEM 17.  UNDERTAKINGS
 
     (a) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant for expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
     (b) The undersigned Registrant hereby undertakes that:
 
          (i) For purposes of determining any liability under the Act, the
     information omitted from the form of prospectus filed as part of this
     registration statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act shall be deemed to be part of this registration
     statement as of the time it was declared effective.
 
          (ii) For the purpose of determining any liability under the Act, each
     post-effective amendment that contains a form of prospectus shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (iii) It will provide to the underwriters at the closing(s) specified
     in the underwriting agreement certificates in such denominations and
     registered in such names as required by the underwriters to permit prompt
     delivery to each purchaser.

      and "Prospectus" means such final prospectus as first filed with the
      Commission pursuant to paragraph (1) or (4) of Rule 424(b) of the Rules

      therein or necessary to make the statements therein not misleading;
      provided that no representation or warranty is made as to information
      contained in or omitted from the Registration Statement or the Prospectus
      in reliance upon and in conformity with written information furnished to
      the Company through the Representatives by or on behalf of any

      good standing under the laws of their respective jurisdictions of
      incorporation, are duly qualified to do business and are in good standing
      as foreign corporations, in each jurisdiction in which their respective
      ownership or lease of property or the conduct of their respective
      businesses requires such qualification, and in which the failure to so
      qualify would, in the aggregate, result in a material adverse effect on
      the stockholders' equity, assets, liabilities, business, results of
      operations, condition (financial or otherwise), cash flows, affairs or
      prospects of the Company and its subsidiaries taken as a whole (a
      "Material Adverse Effect"), and have all power and authority necessary
      (corporate and other) to own or hold their respective properties and to
      conduct the businesses in which they are engaged.  The Company has no
      subsidiaries other than as identified on Annex A hereto.

      subsidiary of the Company have been duly and validly authorized and
      issued and are fully paid, non-assessable and are owned directly or
      indirectly by the Company, free and clear of all liens, encumbrances,
      equities or claims.

           (e) The unissued Shares to be issued and sold by the Company to the
      Underwriters hereunder have been duly and validly authorized and, when
      issued and delivered against payment therefor as provided herein, will be
      duly and validly issued, fully paid and non-assessable and conform to the
      description thereof contained in the Prospectus in the section entitled
      "Description of Capital Stock."

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

           (g) The execution, delivery and performance of this Agreement by the
      Company, the issuance and sale of the Shares (the "Offering") and the
      other transactions contemplated hereby will not conflict with or result
      in a breach or violation of any of the terms or provisions of, or
      constitute a default under, any

                                       4


      indenture, mortgage, deed of trust, loan agreement or other
      agreement or instrument to which the Company or any of its subsidiaries
      is a party or by which the Company or any of its subsidiaries is bound or
      to which any of the property or assets of the Company or any of its
      subsidiaries is subject, which conflicts, breaches, violations or
      defaults would have, individually or in the aggregate, a Material Adverse
      Effect, nor will such actions result in any violation of the provisions
      of the articles of incorporation or by-laws or other organizational
      documents of the Company or any of its subsidiaries or any statute or any
      order, rule or regulation of any court or governmental agency or body
      having jurisdiction over the Company or any of its subsidiaries or any of
      their respective properties or assets; and except for the registration of
      the Shares under the Securities Act and such consents, approvals,
      authorizations, registrations or qualifications as may be required under
      the Securities Exchange Act of 1934 (the "Exchange Act") and applicable
      state securities laws in connection with the purchase and distribution of
      the Shares by the Underwriters, no consent, approval, authorization or
      order of, or filing or registration with, any such court or governmental
      agency or body is required for the execution, delivery and performance of
      this Agreement by the Company and the consummation of the Offering and
      the other transactions contemplated hereby.

           (h) There are no contracts, agreements or understandings between the
      Company and any person granting such person the right to require the
      Company to file a registration statement under the Securities Act with
      respect to any securities of the Company or any of its subsidiaries owned
      or to be owned by such person or to require the Company to include such
      securities in the securities registered pursuant to the Registration
      Statement or in any securities being registered pursuant to any other
      registration statement filed by the Company under the Securities Act.

           (i) Except as described in the Registration Statement or Prospectus,
      the Company has not sold or issued any shares of Common Stock during the
      six month period preceding the date of the Prospectus, including any
      sales pursuant to Rule 144A under, or Regulations D or S of, the
      Securities Act, other than shares issued under employee benefit plans,
      qualified stock options plans or other employee compensation plans or
      pursuant to outstanding options, rights or warrants.  There is no
      commitment, plan or arrangement to issue, and no outstanding option,
      warrant or other right calling for the issuance of, any share of capital
      stock of the Company or of any subsidiary or any security or other
      instrument that by its terms is convertible into, exercisable for, or
      exchangeable for capital stock of the Company.

           (j) Neither the Company nor any of its subsidiaries has sustained,
      since the date of the latest audited financial statements included in the
      Prospectus, any material loss or interference with its business from
      fire, explosion, flood or other calamity, whether or not covered by
      insurance, or from any labor dispute or court or




<PAGE>   5

                                       5


      governmental action, order or decree, otherwise than as set forth or
      contemplated in the Prospectus nor has the Company incurred or undertaken
      any liability or obligation, direct or contingent, that is material to
      the Company except for liabilities or obligations (i) incurred or
      undertaken in the ordinary course of business or (ii) described in the
      Registration Statement; and, since such date, there has not been any
      change in the capital stock or long-term debt of the Company or any of
      its subsidiaries or any material adverse change, or any development
      involving a prospective material adverse change, in or affecting the
      general affairs, management, consolidated financial condition,
      shareholders' equity, results of operations or prospects of the Company
      and its subsidiaries, otherwise than as set forth or contemplated in the
      Prospectus.

           (k) The financial statements (including the related notes and
      supporting schedules) filed as part of the Registration Statement or
      included in the Prospectus present fairly the financial condition and
      results of operations of the entities purported to be shown thereby, at
      the dates and for the periods indicated, and have been prepared in
      conformity with generally accepted accounting principles applied on a
      consistent basis throughout the periods involved.  The pro forma
      financial statements and other pro forma financial information filed as
      part of the Registration Statement or included in the Prospectus present
      fairly the information shown therein, have been prepared in accordance
      with the Commissions rules and guidelines with respect to pro forma
      financial statements, have been properly compiled on the pro forma bases
      described therein and the assumptions used in the preparation thereof are
      reasonable and the adjustments used therein are appropriate to give
      effect to the transactions or circumstances referred to therein.

           (m) The Company and each of its subsidiaries has good and marketable
      title in fee simple to all real property and good and marketable title to
      all personal property owned by them, in each case free and clear of all
      liens, encumbrances, security interests, claims and defects, except such
      as are described in the Prospectus or such as do not materially and
      adversely affect the value of such property and do not materially
      interfere with the use made and proposed to be made of such property by
      the Company and each of its subsidiaries; and all real property and
      buildings held under lease by the Company and each of its subsidiaries is
      held by them under valid, subsisting and enforceable leases, with such
      exceptions as would not have a Material Adverse Effect and do not
      materially interfere with the use made and proposed to be made of such
      property and buildings by the Company and each of its subsidiaries.

           (n) The Company and each of its subsidiaries carry, or are covered
      by, insurance in such amounts and covering such risks as is adequate for
      the conduct of their respective businesses and as is customary for
      companies engaged in similar businesses in similar industries.

           (o) The Company and each of its subsidiaries own or possess adequate
      rights to use all material patents, patent applications, trademarks,
      service marks, trade names, trademark registrations, service mark
      registrations, copyrights and licenses and other intangible properties
      and assets which are both material and necessary for the conduct of their
      businesses and have no reason to believe that the conduct of their
      businesses will conflict with, and have not received any notice of any
      claim of conflict with, any such rights of others, nor, to the best of
      the Company's knowledge, is there an infringement by others of such
      rights of the Company which could reasonably be expected to have a
      Material Adverse Effect.

           (p) Except as described in the Registration Statement and the
      Prospectus, there are no legal or governmental proceedings pending to
      which the Company or any of its subsidiaries is a party or of which any
      property or assets of the Company or any of its subsidiaries is subject
      which, if determined adversely to the Company or any of its subsidiaries,
      might have a Material Adverse Effect; and to the best of the Company's
      knowledge, no such proceedings are threatened or contemplated by
      governmental authorities or threatened by others.

           (q) The Company is in compliance in all material respects with all
      applicable rules and regulations of the Food and Drug Administration (the
      "FDA"), the Federal Trade Commission (the "FTC"), the Consumer Product
      Safety Commission, the United States Department of Agriculture, the Drug

      laws, statutes, ordinances, rules or regulations, the enforcement of
      which, individually or in the aggregate, would be reasonably expected to
      have a Material Adverse Effect.

           (r) There are no contracts or other documents which are required to
      be described in the Prospectus or filed as exhibits to the Registration
      Statement by the Securities Act or by the Rules and Regulations which

      statement of a material fact




<PAGE>   12

                                       12


      or omit to state any material fact required to be stated therein or
      necessary to make the statements therein not misleading; provided that no
      representation or warranty is made as to information contained in or
      omitted from the Registration Statement or the Prospectus in reliance
      upon and in conformity with written information furnished to the Company
      through the Representatives by or on behalf of any Underwriter
      specifically for inclusion therein; and further, each Selling Shareholder
      severally represents, warrants and agrees that the Registration Statement
      and the Prospectus and any further amendments or supplements to the
      Registration Statement or the Prospectus, when they become effective or

      as of the applicable effective date (as to the Registration Statement and
      any amendment thereto) and as of the applicable filing date (as to the
      Prospectus and any amendment or supplement thereto), with respect to any
      information about the Selling Shareholder, contain any untrue statement
      of a material fact or omit to state any material fact required to be
      stated therein or necessary to make the statements therein not
      misleading; provided that no representation or warranty is made as to
      information contained in or omitted from the Registration Statement or
      the Prospectus in reliance upon and in conformity with written
      information furnished to the Company through the Representatives by or on

     3. Purchase of the Shares by the Underwriters.  On the basis of the
representations and warranties contained in, and subject to the terms and
conditions of, this Agreement, the Company agrees to issue and sell 6,000,000
Firm Shares and each Selling Shareholder hereby agrees to sell the number of
Firm Shares set opposite its/his/her name in Schedule 2 hereto, severally and
not jointly, to the several Underwriters and each of the Underwriters,
severally and not jointly, agrees to purchase the number of Firm Shares set
opposite that Underwriter's name in Schedule 1 hereto.  Each Underwriter shall
be obligated to purchase from the Company, and from each Selling Shareholder,
that number of Firm Shares which represent the same proportion of the number of
Firm Shares to be sold by the Company, and by each Selling Shareholder, as the
number of Firm Shares set forth opposite the name of such Underwriter in
Schedule 1 represents of the total number of Firm Shares to be purchased by all
of the Underwriters pursuant to this Agreement.  The respective purchase
obligations of the Underwriters with respect to the Firm Shares shall be
rounded among the Underwriters to avoid fractional shares, as the
Representatives may determine.

     In addition, the Company grants to the Underwriters an option to purchase
up to 1,000,000 Option Shares.  Such option is granted for the purpose of
covering over-allotments in the sale of Firm Shares and is exercisable as
provided in Section 5 hereof.  Option Shares shall be purchased severally for
the account of the Underwriters in proportion to the number of Firm Shares set
opposite the name of such Underwriters in Schedule 1 hereto.  The respective
purchase obligations of each Underwriter with respect to the Option Shares
shall be adjusted by the Representatives so that no Underwriter shall be
obligated to




<PAGE>   13

                                       13


purchase Option Shares other than in 100 share amounts.  The price of both the
Firm Shares and any Option Shares shall be $_____ per share.

     The Company and the Selling Shareholders shall not be obligated to deliver
any of the Shares to be delivered on any Delivery Date (as hereinafter
defined), as the case may be, except upon payment for all the Shares to be
purchased on such Delivery Date as provided herein.


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

     5. Delivery of and Payment for the Shares.  Delivery of and payment for
the Firm Shares shall be made at the offices of Shearman & Sterling, 599
Lexington Avenue, New York, New York 10022 at 10:00 A.M. New York City time, on
the third full business day following the date of this Agreement (or if pricing
of the Firm Shares occurs after 4:30 P.M. New York City time, on the fourth
full business day thereafter) or at such other date or place as shall be
determined by agreement between the Representatives and the Company.  This date
and time are sometimes referred to as the "First Delivery Date."  On the First
Delivery Date, the Company and the Selling Shareholders shall deliver or cause
to be delivered certificates representing the Firm Shares to the
Representatives for the account of each Underwriter against payment to or upon
the order of the Company and the Selling Shareholders of the purchase price by
wire transfer in immediately available funds.  Time shall be of the essence,
and delivery at the time and place specified pursuant to this Agreement is a
further condition of the obligation of each Underwriter hereunder.  Upon
delivery, the Firm Shares shall be registered in such names and in such
denominations as the Representatives shall request in writing not less than two
full business days prior to the First Delivery Date.  For the purpose of
expediting the checking and packaging of the certificates for the Firm Shares,
the Company and the Selling Shareholders shall make the certificates
representing the Firm Shares available for inspection by the Representatives in
New York, New York, not later than 2:00 P.M., New York City time, on the
business day prior to the First Delivery Date.

     The option granted in Section 3 will expire 30 days after the date of this
Agreement and may be exercised in whole or in part from time to time by written
notice being given to the Company by the Representatives.  Such notice shall
set forth the aggregate number of Option Shares as to which the option is being
exercised, the names in which the Option Shares are to be registered, the
denominations in which the Option Shares are to be issued and the date and
time, as determined by the Representatives, when the Option Shares are to be
delivered; provided, however, that this date and time shall not be earlier than
the First Delivery Date, nor earlier than the second business day after the
date on which the




<PAGE>   14

                                       14


option shall have been exercised nor later than the fifth business day after
the date on which the option shall have been exercised.  The date and time 
the Option Shares are delivered are sometimes referred to as a "Second Delivery
Date" and the First Delivery Date and any Second Delivery Date are sometimes 
referred to as a "Delivery Date."

           Delivery of and payment for the Option Shares shall be made at the 
place specified in the first sentence of the first paragraph of this Section 5

or cause to be delivered the certificates representing the Option Shares to the
Representatives for the account of each Underwriter against payment to or upon
the order of the Company of the purchase price by wire transfer in immediately
available funds.  Time shall be of the essence, and delivery at the time and
place specified pursuant to this Agreement is a further condition of the
obligation of each Underwriter hereunder.  Upon delivery, the Option Shares
shall be registered in such names and in such denominations as the
Representatives shall request in the aforesaid written notice.  For the purpose
of expediting the checking and packaging of the certificates for the Option
Shares, the Company shall make the certificates representing the Option Shares
available for inspection by the Representatives in New York, New York, not later
than 2:00 P.M., New York City Time, on the business day prior to such Second
Delivery Date.

      counsel needs express no opinion), as of the dates they were filed with
      the Commission, contained an untrue statement of a material fact or
      omitted to state a material fact required to be stated therein or
      necessary to make the statements therein not misleading.

            distribution of the Shares by the Underwriters, no consent,
            approval, authorization or order of, or filing or registration
            with, any such court or governmental agency or body is required for
            the execution, delivery and performance of this Agreement, the

      matters governed by the laws of jurisdictions other than the federal law
      of the United States of America, the laws of the State of New York and
      the General Corporation Law of the State of Tennessee, upon opinions of
      other counsel, who shall be counsel satisfactory to counsel for the
      Underwriters, in which case the opinion shall state that they believe you
      and they are entitled to so rely, and (ii) in rendering the opinion in
      Section 9(e) above, rely upon a certificate of each Selling Shareholder
      in respect of matters of fact as to ownership of and liens, encumbrances,
      equities or claims on the shares of Common Stock sold by such Selling
      Shareholder, provided that such counsel shall furnish copies thereof to
      the Representatives and state that it believes that both the Underwriters
      and it are justified in relying upon such certificate.  On each Delivery
      Date, such counsel shall also have furnished to the Representatives a
      written statement, addressed to the Underwriters and dated such Delivery
      Date, in form and substance satisfactory to the Representatives, to the
      effect that (x) such counsel has acted as counsel to each Selling
      Shareholder in connection with the preparation of the Registration
      Statement, and (y) based on the foregoing, no facts have come to the
      attention of such counsel which lead it to believe that the Registration
      Statement, as of the Effective Date, contained any untrue statement of a
      material fact relating to any Selling Shareholder or omitted to state
      such a material fact required to be stated therein or necessary in order
      to make the statements therein not misleading, or that the Prospectus
      contains any untrue statement of a material fact relating to any Selling
      Shareholder or omits to state such a material fact required to be stated
      therein or necessary in order to make the statements therein, in light of
      the circumstances under which they were made, not misleading.

      the Representatives its written opinion, as counsel to the Selling
      Shareholders named in  Schedule III hereto for whom it is acting as

            and valid title to the Shares to be sold by such Selling

            title to the Shares to be sold by each Selling Shareholder under
            this Agreement, free and clear of all claims, liens, encumbrances,
            equities or claims, has been transferred to each of the several
            Underwriters, assuming that such Underwriters have purchased such
            shares in good faith and without notice of any such claim, lien,
            encumbrance, equities security interests or restrictions on
            transfer or any other adverse claim within the meaning of the
            Uniform Commercial Code; and

                 (v)   To the best knowledge of such counsel, each Selling
            Shareholder has all necessary power and authority to execute and
            deliver this Agreement, the Power of Attorney and the Custody

            execution, delivery and performance of this Agreement, the Power of
            Attorney and the Custody Agreement by the Selling Shareholder and
            the consummation by the Selling Shareholder of the transactions

            a breach or violation of any of the terms or provisions of, or
            constitute a default under, any statute, any material indenture,
            mortgage, deed of trust, loan agreement or other material agreement

            Shareholder is a party or by which the Selling Shareholder is bound

            Shareholder is subject, nor will such actions

            result in any violation of the charter or by-laws of the
            Selling Shareholder or any statute or any order, rule or regulation
            known to such counsel of any court or governmental agency or body
            having jurisdiction over the Selling Shareholder or the property or
            assets of the Selling Shareholder; and, except for the registration
            of the Shares under the Securities Act and such consents,
            approvals, authorizations, registrations or qualifications as may
            be required under the Exchange Act and applicable state or foreign

            or order of, or filing or registration with, any such court or
            governmental agency or body is required for the execution, delivery
            and performance of this Agreement, the Power of Attorney or the
            Custody Agreement by the Selling Shareholder and the consummation

            and thereby.

            In rendering such opinion, such counsel (i) may rely, as to all
      matters governed by the laws of jurisdictions other than the federal law
      of the United States of America, the laws of the State of New York (the
      laws of which such counsel is allowed to assume, for purposes of such
      opinion, are identical to the laws of the State of Tennessee) and the
      General Corporation Law of the State of Tennessee, upon opinions of other
      counsel, who shall be counsel satisfactory to counsel for the
      Underwriters, in which case the opinion shall state that they believe you
      and they are entitled to so rely, and (ii) in rendering the opinion in
      Section 9(e) above, rely upon a certificate of each Selling Shareholder
      in respect of matters of fact as to ownership of and liens, encumbrances,
      equities or claims on the shares of Common Stock sold by such Selling
      Shareholder, provided that such counsel shall furnish copies thereof to
      the Representatives and state that it believes that both the Underwriters
      and it are justified in relying upon such certificate.  On each Delivery
      Date, such counsel shall also have furnished to the Representatives a
      written statement, addressed to the Underwriters and dated such Delivery
      Date, in form and substance satisfactory to the Representatives, to the
      effect that (x) such counsel has acted as counsel to each Selling
      Shareholder in connection with the preparation of the Registration
      Statement, and (y) based on the foregoing, no facts have come to the
      attention of such counsel which lead it to believe that the Registration
      Statement, as of the Effective Date, contained any untrue statement of a
      material fact relating to any Selling Shareholder or omitted to state
      such a material fact required to be stated therein or necessary in order
      to make the statements therein not misleading, or that the Prospectus
      contains any untrue statement of a material fact relating to any Selling
      Shareholder or omits to state such a material fact required to be stated
      therein or necessary in order to make the statements therein, in light of
      the circumstances under which they were made, not misleading.

           (g)   McKenna & Cuneo, L.L.P. shall have furnished to the
      Representatives its written opinion, as special regulatory counsel to the
      Company, addressed to the Underwriters and dated such Delivery Date, in
      form and substance satisfactory to the Representatives to the effect
      that:

   
                 (i)   The statements and descriptions made in the Prospectus
            under the captions "Risk Factors--Government Regulation" and
            "Business--Government Regulation" to the extent that they
            constitute matters of law or legal conclusions, have been reviewed
            by us and fairly present the information required to be disclosed
            therein in all material respects and nothing has come to our
            attention which leads us to believe that (A) the information set
            forth in the Registration Statement, or any amendment thereto,
            under the captions referred to above as of the time the Registration
            Statement became effective under the Securities Act, and as of the
            Delivery Date, contained an untrue statement of a material fact or
            omitted to state a material fact required to be stated therein or
            necessary to make the statements therein not misleading and (B) the
            information set forth in the Prospectus, or in any supplement
            thereto, under the captions referred to above as of its issue date
            and as of such Delivery Date, contained an untrue statement of a
            material fact or omitted to state a material fact, necessary to
            make the statements therein, in the light of the circumstances
            under which they were made, not misleading.
    

                 (ii)  The execution and delivery of the Underwriting Agreement
            and the consummation of the transactions contemplated in the
            Underwriting Agreement do not and will not conflict with, or result
            in a breach of any of the terms or provisions of, or constitute
            default under, or result in the creation of a lien, charge or
            encumbrance upon any property or assets of the Company or any of
            its subsidiaries under any existing applicable federal or state
            law, rule or regulation governing the sale or distribution of
            pharmaceutical products of the pharmaceutical industry generally or
            the relationship between pharmacists and customers.

                 (iii) Such counsel does not know of any federal or state law,
            rules or regulations governing the sale or distribution of
            pharmaceutical products or the pharmaceutical industry generally or
            the relationship between pharmacists and customers, or any pending
            or threatened legal or governmental proceedings in respect of such
            statutes, rules or regulations, required to be described in the
            Prospectus that are not described as required.

                 (iv)  The descriptions in the Prospectus of the federal and
            state laws, rules or regulations governing the sale or distribution
            of pharmaceutical products or the pharmaceutical industry
            generally, and the legal or




<PAGE>   29

                                       29


            governmental proceedings in respect of such laws, rules or
            regulations, fairly summarize the information required to be shown.

                 (v) Such counsel has no reason to believe that the Company's
            current business is not being conducted in material compliance with
            currently applicable requirements under the Federal Food, Drug and
            Cosmetic Act or that the U.S. Food and Drug Administration is
            currently considering taking action that would result in withdrawal
            from marketing of any of the Company's currently marketed products.

           In giving its opinion, such counsel may state that (1) such
      counsel's opinion is limited to matters governed by the applicable
      regulations described above, and (2) such counsel has not conducted an
      audit of the Company.  The foregoing opinion may be qualified by
      statements to the effect that (1) while such counsel has had
      conversations with the Company's employees and the Company's regulatory
      advisors and reviewed certain relevant documents as such counsel deems
      necessary and appropriate, such counsel has not verified the accuracy or
      validity of the facts set forth in the Prospectus, and (2) in such
      counsel's examinations, such counsel has assumed the genuineness of all
      signatures, the authenticity of all documents submitted to such counsel
      as originals and the conformity with the originals of all documents
      submitted to such counsel as copies.

   
           (h)   Roberts & Brownell, LLC shall have furnished to the 
      Representatives its written opinion, as special patent counsel for the
      Company, addressed to the Underwriters (and stating that it may be relied
      upon by counsel to the Underwriters) and dated such Delivery Date to the
      effect that:
    
                 (i) The statements and descriptions made in the Prospectus
            under the caption "Business--Patents, Trademarks and Proprietary
            Property" to the extent that they constitute matters of law or
            legal conclusions, have been reviewed by us and fairly present the
            information required to be disclosed therein in all material
            respects and nothing has come to our attention which leads us to
            believe that (A) the information set forth in the Registration
            Statement, or any amendment thereto, under the caption referred to
            above as of the time the Registration Statement became effective
            under the Securities Act, and as of the Delivery Date, contained an
            untrue statement of a material fact or omitted to state a material
            fact required to be stated therein or necessary to make the
            statements therein not misleading and (B) the information set forth
            in the Prospectus, or in any supplement thereto, under the caption
            referred to above as of its issue date and as of such Delivery
            Date, contained an untrue statement of a material fact or omitted
            to state a material

            fact, necessary to make the statements therein, in the light
            of the circumstances under which they were made, not misleading.

                 (ii) Such counsel has no knowledge of any pending or
            threatened legal or governmental proceeding relating to patents or
            proprietary know-how owned or used by the Company or any of its
            subsidiaries, to which the Company or any of its subsidiaries is a
            party or to which any of the properties of the Company or any of
            its subsidiaries is subject, except as disclosed in the
            Registration Statement, which, if adversely decided, would have a
            material adverse effect on the business, financial condition or
            results of operations of the Company or any of its subsidiaries,
            taken as a whole.

                 (iii) Such counsel has no knowledge of any infringement or
            alleged infringement by the Company or any of its subsidiaries of
            issued patent rights of others, except as disclosed in the
            Registration Statement, which would have a material adverse effect
            on the business, financial condition or results of operations of
            the Company and its subsidiaries, taken as a whole.

   
           (i) You shall have received from Shearman & Sterling, counsel for
      the Underwriters, such opinions dated such Delivery Date, with respect to
      the Registration Statement, the Prospectus and other related matters as
      you reasonably may request, and such counsel shall have received such
      papers and information as they reasonably request to enable them to pass
      upon such matters.  In giving such opinions, Shearman & Sterling is
      entitled to rely on the opinion of Baker, Donelson, Bearman & Caldwell,
      counsel to the Company.
    

           (j) (A) With respect to the letters of Coopers & Lybrand L.L.P.

            or any change, in or affecting the general affairs, management,
            business, financial condition, shareholders' equity or results of
            operations of the Company and its subsidiaries taken as a whole,
            except as set forth or contemplated in the Prospectus; and

                 (iii) They have carefully examined the Registration Statement
            and the Prospectus and, in their opinion (A) as of the Effective
            Date, the Registration Statement and Prospectus did not include any
            untrue statement of a material fact and did not omit to state a
            material fact required to be stated therein or necessary to make
            the statements therein not misleading, and (B) since the Effective
            Date no event has occurred which should have been set forth in a
            supplement or amendment to the Registration Statement or the
            Prospectus.

           (l) Each Selling Shareholder (or one or more attorneys-in-fact on
      behalf of the Selling Shareholders) shall have furnished to the
      Representatives a certificate, dated the Delivery Date, signed by, or on
      behalf of, the Selling Shareholder (or one or more attorneys-in-fact)
      stating that the representations, warranties and agreements




<PAGE>   32

                                       32


      of the Selling Shareholder contained herein are timely and correct
      as of the Delivery Date and that the Selling Shareholder has complied
      with all agreements contained herein to be performed by the Selling
      Shareholder at or prior to the Delivery Date.

           (m) Neither the Company nor any of its subsidiaries shall have
      sustained, since the date of the latest audited financial statements
      included in the Prospectus, any loss or interference with its business
      from fire, explosion, flood or other calamity, whether or not covered by
      insurance, or from any labor dispute or court or governmental action,
      order or decree, otherwise than as set forth or contemplated in the
      Prospectus; and since such date, there shall not have been any change in
      the capital stock or long-term debt of the Company or any of its
      subsidiaries or any change, or any development involving a prospective
      change, in or affecting the general affairs, management, business,
      financial condition, shareholders' equity, results of operations or
      prospects of the Company and its subsidiaries taken as a whole, except as
      set forth or contemplated in the Prospectus, the effect of which, in the
      reasonable judgment of the Representatives, is so material and adverse as
      to make it impracticable or inadvisable to proceed with the public
      offering or the delivery of the Shares being delivered on such Delivery
      Date on the terms and in the manner contemplated in the Prospectus.

           (n) Subsequent to the execution and delivery of this Agreement there
      shall not have occurred any of the following:  (i) trading in securities
      generally on the New York Stock Exchange, the American Stock Exchange or
      the over-the-counter market shall have been suspended or minimum prices
      shall have been established on either of such exchanges or such market by
      the Commission by such exchange or by any other regulatory body or
      governmental authority having jurisdiction, (ii) a banking moratorium
      shall have been declared by Federal or state authorities, (iii) the
      United States shall have become engaged in hostilities, there shall have
      been an escalation in hostilities involving the United States or there
      shall have been a declaration of a national emergency or war by the
      United States or (iv) there shall have occurred such a material adverse
      change in general economic, political or financial conditions (or the
      effect of international conditions on the financial markets in the United
      States shall be such) as to make it, in the judgment of a majority in
      interest of the several Underwriters, impracticable or inadvisable to
      proceed with the public offering or delivery of the Shares being
      delivered on such Delivery Date on the terms and in the manner
      contemplated in the Prospectus.

           (o) The Nasdaq National Market shall have approved the Shares for
      listing, subject only to official notice of issuance and evidence of
      satisfactory distribution.

   
           (p) The Representatives shall have received Lock-up Letters from each
      holder of shares constituting (or shares convertible into, or options
      exercisable for) at

                                       33


      least 3.0 percent of the Common Stock of the Company and each
      officer and director of the Company.

           (q) The National Association of Securities Dealers, Inc., upon
      review of the terms of the underwriting arrangements for the public
      offering of the Common Stock, shall have raised no objection thereto.

           (r) Prior to any Delivery Date, the Company shall have furnished to
      the Representatives such other information, certificates and documents as
      they may reasonable request.

           All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance satisfactory to
counsel for the Underwriters.

     10.   Indemnification and Contribution.

     (a)   The Company shall indemnify and hold harmless each Underwriter, its
officers and employees and each person, if any, who controls any Underwriter
within the meaning of the Securities Act, from and against any loss, claim,
damage or liability, joint or several, or any action in respect thereof
(including, but not limited to, any loss, claim, damage, liability or action
relating to purchases and sales of Shares), to which that Underwriter, officer,
employee or controlling person may become subject, under the Securities Act or
otherwise, insofar as such loss, claim, damage, liability or action arises out
of, or is based upon, (i) any untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement, the Prospectus or in any amendment or supplement thereto or (ii) the
omission or alleged omission to state in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or in any amendment or supplement
thereto any material fact required to be stated therein or necessary to make
the statements therein not misleading, or (iii) any act or failure to act or
any alleged act or failure to act by any Underwriter in connection with, or
relating in any manner to, the Common Stock or the offering contemplated
hereby, and which is included as part of or referred to in any loss, claim,
damage, liability or action arising out of or based upon matters covered by
clause (i) or (ii) above (provided that the Company shall not be liable under
this clause (iii) to the extent that it is determined in a final judgment by a
court of competent jurisdiction that such loss, claim, damage, liability or
action resulted directly from any such acts or failures to act undertaken or
omitted to be taken by such Underwriter through its gross negligence or willful
misconduct) and shall reimburse each Underwriter and each such officer,
employee or controlling person promptly upon demand for any legal or other
expenses reasonably incurred by that Underwriter, officer, employee or
controlling person in connection with investigating or defending or preparing
to defend against any such loss, claim, damage, liability or action as such
expenses are incurred; provided, however,




<PAGE>   34

                                       34


that the Company shall not be liable in any such case to the extent that any
such loss, claim, damage, liability or action arises out of, or is based upon,
any untrue statement or alleged untrue statement or omission or alleged
omission made in any Preliminary Prospectus, the Registration Statement or the
Prospectus or in any such amendment or supplement in reliance upon and in
conformity with written information concerning such Underwriter furnished to
the Company through the Representatives by or on behalf of any Underwriter
specifically for inclusion therein, which information is comprised solely of
the information set forth in Section 10(e) hereof.  The foregoing indemnity
agreement is in addition to any liability which the Company may otherwise have
to any Underwriter or to any officer, employee or controlling person of that
Underwriter.

     (b) The Selling Shareholders, severally in proportion to the number of
Shares to be sold by each of them hereunder, shall indemnify and hold harmless
each Underwriter, its officers and employees and each person, if any, who
controls any Underwriter within the meaning of the Securities Act, from and
against any loss, claim, damage or liability, joint or several, or any action
in respect thereof (including, but not limited to, any loss, claim, damage,
liability or action relating to purchases and sales of Shares), to which that
Underwriter, officer, employee or controlling person may become subject, under
the Securities Act or otherwise, insofar as such loss, claim, damage, liability
or action arises out of, or is based upon, (i) any untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus,
the Registration Statement or the Prospectus or in any amendment or supplement
thereto or (ii) the omission or alleged omission to state in any Preliminary
Prospectus, Registration Statement or the Prospectus or in any amendment or
supplement thereto any material fact required to be stated therein or necessary
to make the statements therein not misleading, but in each case for each
Selling Shareholder that is not an executive officer or director of the Company
as set forth in the Registration Statement, only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information concerning such
Selling Shareholder furnished to the Company specifically for inclusion
therein, and shall reimburse each Underwriter, its officers and employees and
each such controlling person for any legal or other expenses reasonably
incurred by that Underwriter, its officers and employees or controlling person
in connection with investigating or defending or preparing to defend against
any such loss, claim, damage, liability or action as such expenses are
incurred; provided, however, that the Selling Shareholders shall not be liable
in any such case to the extent that any such loss, claim, damage, liability or
action arises out of, or is based upon, any untrue statement or alleged untrue
statement or omission or alleged omission made in any Preliminary Prospectus,
the Registration Statement or the Prospectus or in any such amendment or
supplement in reliance upon and in conformity with written information
concerning such Underwriter furnished to the Company through the
Representatives by or on behalf of any Underwriter specifically for inclusion
therein, which information is comprised solely of the information set forth in
Section 10(e) hereof; and provided further, that the aggregate liability shall
be limited to the




<PAGE>   35

                                       35


gross proceeds received by such Selling Shareholder.  The foregoing indemnity
agreement is in addition to any liability which the Selling Shareholders may
otherwise have to any Underwriter or any officer, employee or controlling
person of that Underwriter.

     (c) Each Underwriter, severally and not jointly, shall indemnify and hold
harmless the Company, its officers and employees, each of its directors and
each person, if any, who controls the Company within the meaning of the
Securities Act and the Selling Shareholders, from and against any loss, claim,
damage or liability, joint or several, or any action in respect thereof, to
which the Company, any such director, officer or controlling person or any
Selling Shareholder may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained in any Preliminary Prospectus, the Registration Statement or the
Prospectus or in any amendment or supplement thereto or (ii) the omission or
alleged omission to state in any Preliminary Prospectus, the Registration
Statement or the Prospectus or in any amendment or supplement thereto any
material fact required to be stated therein or necessary to make the statements
therein not misleading but in each case only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information concerning such
Underwriter furnished to the Company through the Representatives by or on
behalf of that Underwriter specifically for inclusion therein, and shall
reimburse the Company, any such director, officer or controlling person  and
any Selling Shareholder for any legal or other expenses reasonably incurred by
the Company, any such director, officer or controlling person or any Selling
Shareholder in connection with investigating or defending or preparing to
defend against any such loss, claim, damage, liability or action as such
expenses are incurred.  The foregoing indemnity agreement is in addition to any
liability which any Underwriter may otherwise have to the Company or any such
director, officer, employee or controlling person.

     (d) Promptly after receipt by an indemnified party under this Section 10
of notice of any claim or the commencement of any action, the indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under this Section 10, notify the indemnifying party in writing of the
claim or the commencement of that action; provided, however, that the failure
to notify the indemnifying party shall not relieve it from any liability which
it may have under this Section 10 except to the extent it has been materially
prejudiced by such failure, and provided, further, that the failure to notify
the indemnifying party shall not relieve it from any liability which it may
have to an indemnified party otherwise than under this Section 10.  If any such
claim or action shall be brought against an indemnified party, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled
to participate therein and, to the extent that it wishes, jointly with any
other similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party.  After notice from
the indemnifying party to the indemnified party of its election to assume the
defense of such




<PAGE>   36

                                       36


claim or action, the indemnifying party shall not be liable to the indemnified
party under this Section 10 for any legal or other expenses subsequently
incurred by the indemnified party in connection with the defense thereof other
than any reasonable costs of investigation; provided, however, that the
Representatives shall have the right to employ counsel to represent jointly the
Representatives and those other Underwriters and their respective officers,
employees and controlling persons who may be subject to liability arising out
of any claim in respect of which indemnity may be sought by the Underwriters
against the Company or any Selling Shareholder under this Section 10, if in the
reasonable judgment of the Representatives, it is advisable for the
Representatives and those Underwriters, officers, employees and controlling
persons to be jointly represented by separate counsel, and in that event the
fees and expenses of such separate counsel shall be paid by the Company and the
Selling Shareholders.  No indemnifying party shall (i) without the prior
written consent of the indemnified parties (which consent shall 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 (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 indemnified party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for
any settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with the consent of
the indemnifying party or if there be a final judgment of the plaintiff in any
such action, the indemnifying party agrees to indemnify and hold harmless any
indemnified party from and against any loss or liability by reason of such
settlement or judgment.

     (e) If the indemnification provided for in this Section 10 shall for any
reason be unavailable to or insufficient to hold harmless an indemnified party
under Section 10(a), 10(b) or 10(c) in respect of any loss, claim, damage or
liability or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company and each of the Selling Shareholders on the one hand
and the Underwriters on the other from the offering of the Shares or (ii) if
the allocation provided by clause (i) above is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company and
each of the Selling Shareholders on the one hand and the Underwriters on the
other with respect to the statements or omissions which resulted in such loss,
claim, damage or liability, or action in respect thereof, as well as any other
relative equitable considerations.  The relative benefits received by the
Company and each of the Selling Shareholders on the one hand and the
Underwriters on the other with respect to such offering shall be deemed to be
in the same proportion as the total net proceeds from the offering of




<PAGE>   37

                                       37


the Shares purchased under this Agreement (before deducting expenses) received
by the Company and each of the Selling Shareholders, on the one hand, and the
total underwriting discounts and commissions received by the Underwriters with
respect to the Shares purchased under this Agreement, on the other, bear to the
total gross proceeds from the offering of the Shares under this Agreement, in
each case as set forth in the table on the cover page of the Prospectus.  The
relative fault shall be determined by reference to 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, each
of the Selling Shareholders or the Underwriters, the intent of the parties and
their relative knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission.  The Company, each of the Selling
Shareholders and the Underwriters agree that it would not be just and equitable
if contributions pursuant to this Section 10(e) were to be determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take into account
the equitable considerations referred to herein.  The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability or
action in respect thereof, referred to above in this Section 10(e) shall be
deemed to include, for purposes of this Section 10(e), any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 10(e), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the Shares underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages which such Underwriter has otherwise
paid or become liable to pay by reason of any untrue or alleged untrue
statement or omission or alleged omission.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The Underwriters' obligations to contribute as
provided in this Section 10(e) are several in proportion to their respective
underwriting obligations and not joint.

     (f) The Underwriters severally confirm and the Company acknowledges that
the statements with respect to the public offering of Common Stock by the
Underwriters set forth on the cover page of, the legend concerning
over-allotments on the inside front cover page of, and the concession and
reallowance figures appearing under the caption "Underwriting" in, the
Prospectus are correct and constitute the only information concerning such
Underwriters furnished in writing to the Company by or on behalf of the
Underwriters specifically for inclusion in the Registration Statement and the
Prospectus.

     11. Defaulting Underwriters.  If, on either Delivery Date, any Underwriter
defaults in the performance of its obligations under this Agreement, the
remaining non-defaulting Underwriters shall be obligated to purchase the Shares
which the defaulting Underwriter agreed but failed to purchase on such Delivery
Date in the respective proportions which the number of shares of the Firm
Shares set opposite the name of the




<PAGE>   38

                                       38


remaining non-defaulting Underwriters in Schedule I hereto bears to the total
number of the Firm Shares set opposite the names of all remaining
non-defaulting Underwriters in Schedule I hereto; provided, however, that the
remaining non-defaulting Underwriters shall not be obligated to purchase any of
the Shares on such Delivery Date if the total number of Shares which the
defaulting Underwriter agreed but failed to purchase on such date exceeds 9.09%
of the total number of Shares to be purchased on such Delivery Date, and any
remaining non-defaulting Underwriters shall not be obligated, to purchase more
than 110% of the number of Shares which it agreed to purchase on such Delivery
Date pursuant to the terms of Section 3.  If the foregoing maximums are
exceeded, the remaining non-defaulting Underwriters, or those other
underwriters satisfactory to the Representatives who so agree, shall have the
right, but shall not be obligated, to purchase, in such proportion as may be
agreed upon among them, all Shares to be purchased on such Delivery Date.  If
the remaining Underwriters, or other underwriters satisfactory to the
Representatives, do not elect to purchase the shares which the defaulting
Underwriter agreed but failed to purchase on such Delivery Date, this Agreement
(or, with respect to any Second Delivery Date, the obligation of the
Underwriters to purchase, and of the Company to sell, the Option Shares) shall
terminate without liability on the part of any non-defaulting Underwriters or
the Company or the Selling Shareholders, except that the Company will continue
to be liable for the payment of expenses to the extent set forth in Sections 8
and 13.  As used in this Agreement, the term "Underwriter" includes, for all
purposes of this Agreement unless the context requires otherwise, any party not
listed in Schedule I hereto who, pursuant to this Section 10, purchases Firm
Shares which a defaulting Underwriter agreed but failed to purchase.

     Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company and the Selling Shareholders, for damages
caused by its default.  If other underwriters are obligated to agree to
purchase the Shares of a defaulting or withdrawing Underwriter, either the
Representatives or the Company may postpone the First Delivery Date for up to
seven full business days in order to effect any changes that in the opinion of
counsel for the Company or counsel for the Underwriters may be necessary in the
Registration Statement, the Prospectus or in any other document or arrangement.

     12. Termination.  The obligations of the Underwriters hereunder may be
terminated by the Representatives by notice given to and received by the
Company and the Selling Shareholders prior to delivery of and payment for the
Firm Shares if, prior to that time, any of the events described in Sections
9(l) or 9(m) shall have occurred or if the Underwriters shall decline to
purchase the Shares for any reason permitted under this Agreement.

     13. Reimbursement of Underwriters' Expenses.  If the Company or any
Selling Shareholder shall fail to tender the Shares for delivery to the
Underwriters by reason of any failure, refusal or inability on the part of the
Company or any Selling Shareholder to




<PAGE>   39

                                       39


perform any agreement on its part to be performed or because any other
condition of the Underwriters' obligations hereunder required to be fulfilled
by the Company or the Selling Shareholder is not fulfilled, the Company and the
Selling Shareholders will reimburse the Underwriters for all reasonable
out-of-pocket expenses (including reasonable fees and disbursements of counsel)
incurred by the Underwriters in connection with this Agreement and the proposed
purchase of the Shares, and upon demand the Company and the Selling
Shareholders shall pay the full amount thereof to the Representatives.  If this
Agreement is terminated pursuant to Section 11 by reason of the default of one
or more Underwriters, neither the Company nor any Selling Shareholder shall be
obligated to reimburse any defaulting Underwriter on account of those expenses.

     14.   Notices, Etc.  All statements, requests, notices and agreements
hereunder shall be in writing, and:

         Re: Registration Statement on Form S-1

Dear Board of Directors:

         We have acted as counsel to King Pharmaceuticals, Inc., a Tennessee
corporation (the "Company"), in connection with the registration of 8,919,000
shares of Common Stock (the "Common Stock") of the Company. The Company has
filed a Registration Statement on Form S-1 pursuant to the Securities Act of
1933, as amended (the "Registration Statement").

         We have acted as counsel for the Company in connection with the
proposed transaction and have assisted with the preparation of the Registration
Statement and various corporate documents related thereto. We have examined and
relied upon the following documents and instruments for the purpose of giving
this opinion, which, to our knowledge and in our judgment, are all of the
documents and instruments that are necessary for us to examine for such purpose:

         1.  The Registration Statement, the prospectus filed therewith (the
             "Prospectus") and all exhibits thereto;

         2.  A copy of the Company's Charter certified by the Tennessee
             Secretary of State;

         3.  A copy of the Company's Bylaws certified by the Secretary of the
             Company;

         4.  The minute book of the Company; and

Page 2

         5.  The stock records of the Company.

         In giving our opinion, we have assumed without investigation the
authenticity of any document or instrument submitted to us as an original, the
conformity to the authentic original of any document or instrument submitted to
us as a certified, conformed or photostatic copy and the genuineness of all
signatures on such originals or copies.

         Based upon the foregoing and having regard for such legal
considerations as we deem relevant, we are of the opinion that (i) the Company
is a corporation duly incorporated and validly existing under the laws of the
State of Tennessee and (ii) the Common Stock, when issued in accordance with the
Registration Statement, will be validly issued, fully paid and nonassessable.

         Our opinion is subject to the following qualifications and limitations:

         i.   The opinions expressed herein are subject to the effect of
applicable bankruptcy, insolvency, reorganization or similar laws affecting the
enforcement of creditors' rights and equitable principles limiting the
availability of equitable remedies on the enforceability of contracts,
agreements and instruments.

         ii.  Members of our firm are qualified to practice law in the State of
Tennessee and nothing contained herein shall be deemed to be an opinion as to
any law, rule or regulation other than the law of the State of Tennessee and the
federal law of the United States.

         iii. The opinions set forth herein are expressed as of the date hereof
and, except during the time prior to the effectiveness of the Registration
Statement filed with the Securities and Exchange Commission, we disclaim any
undertaking to advise you of any changes which may subsequently be brought to
our attention in the facts and the law upon which such opinions are based.

         This opinion is intended to be used as an exhibit to the Registration
Statement filed with the Securities and Exchange Commission. Except for such
use, neither this opinion nor copies hereof may be relied upon by, delivered to,
or quoted in whole or in part without our prior written consent.

         We consent to the reference of our firm name under the caption LEGAL
MATTERS in the Prospectus and to the use of our opinion as an exhibit to the
Registration Statement. In giving these consents, we do not admit that we come
within the category of persons whose consent is

                          TOLL MANUFACTURING AGREEMENT
                                       FOR
                      APAP/HYDROCODONE BITARTRATE TABLETS

         This Toll Manufacturing Agreement for APAP/Hydrocodone Bitartrate
Tablets ("Manufacturing Agreement") is made and entered into on and as of
December 13, 1995, by and between Mallinckrodt Chemical, Inc. ("Mallinckrodt"),
and King Pharmaceuticals, Inc. ("King").

         WHEREAS, contemporaneously herewith, Mallinckrodt, King and King
Pharmaceuticals of Nevada, Inc. ("King-Nevada") have entered into an Asset
Purchase Agreement ("Asset Purchase Agreement") pursuant to which Mallinckrodt
is purchasing from King-Nevada, among other things and on the terms and
conditions stated therein, the Current Products and the Future Products, which
represent various dosage strengths of APAP/hydrocodone bitartrate tablets;

         WHEREAS, Mallinckrodt and King recognize that it will require some
substantial period of time before all applicable regulatory requirements are met
allowing Mallinckrodt to commence the manufacture of commercial dosage
formulations represented by the Current Products or the Future Products (when
available) at Mallinckrodt's facilities or a facility designated by Mallinckrodt
and, in any event., Mallinckrodt is currently not capable of undertaking such
manufacture;

         WHEREAS, King and Mallinckrodt therefore wish to provide for continued
production by King of the Current Products from and after the date hereof, and
the Future Products at such time as commercial production becomes possible,
until such time as it becomes possible for Mallinckrodt to commence manufacture
of dosage formulations elsewhere;

         WHEREAS, both Mallinckrodt and King understand that the performance of
manufacturing services by King for an extended period of time is essential for
Mallinckrodt to realize the benefit of its bargain under the terms of the Asset
Purchase Agreement and, therefore, Mallinckrodt will be relying on King's
performance of such services on a continuing basis;



                                       1
<PAGE>   2



         WHEREAS, Mallinckrodt is willing to provide King, at no cost to King,
with the necessary quantities of APAP and hydrocodone bitartrate (hereinafter
jointly referred to as "Key Materials") to allow King to toll process the dosage
formulations represented by the Current Products and Future Products for the
benefit of Mallinckrodt;

         WHEREAS, Mallinckrodt and King are willing to proceed with the toll
manufacturing of the dosage formulations represented by the Current Products and
Future Products (when available) on such terms and conditions as are set forth
herein; and

         WHEREAS, any capitalized terms or any other terms specifically defined
in the Asset Purchase Agreement used herein shall have the meaning ascribed to
them in the Asset Purchase Agreement, unless otherwise expressly set forth
herein.

         NOW, THEREFORE, in consideration of the premises, covenants and
representations of the parties set forth herein, and other good and sufficient
consideration receipt of which is hereby acknowledged, King and Mallinckrodt
agree as follows:

         1.       MANUFACTURING SERVICES.

                  (a)      In consideration of the promises and undertakings of
                           Mallinckrodt set forth in the Asset Purchase
                           Agreement, and for the consideration provided herein
                           and in accordance with all terms, conditions,
                           representations and warranties set forth herein, for
                           the term hereof, and subject to Mallinckrodt's
                           purchase of required minimum volumes pursuant to the
                           provisions of Section 6 hereof, King will manufacture
                           Mallinckrodt's requirements for all tablet dosage
                           formulations that may be produced in accordance with
                           the right and authority for production granted
                           pursuant to any ANDAs (or supplements thereto)
                           concerning the Current Products or the Future
                           Products. All manufacturing by King in accordance
                           herewith shall take place at Kings Bristol Facility
                           or at such other facility owned or leased by King as
                           the parties may agree and as the FDA may approve. In
                           addition, all manufacturing by King hereunder shall
                           be done strictly in accordance with cGMP using the
                           manufacturing process described in the appropriate
                           ANDAs (or supplements thereto) concerning the Current

                           Products and Future Products, as appropriate. At all
                           times during the term hereof, King will take all
                           actions necessary to ensure that it utilizes its
                           available Drug Enforcement Administration ("DEA")
                           manufacturing quota in such a manner as to guarantee
                           that Mallinckrodt will receive its full requirements
                           for APAP/hydrocodone bitartrate tablets hereunder and
                           will further take all actions available to it to
                           ensure that its manufacturing quota is consistently
                           maintained at a level that is adequate for the
                           performance of its obligations hereunder under any
                           reasonably possible set of circumstances that may
                           affect such performance. King will immediately, but
                           in no event more than five (5) days after receipt
                           thereof, provide Mallinckrodt with a copy of any
                           communication it receives from the DEA relative
                           to its quota for hydrocodone bitartrate or relating
                           in any manner whatsoever to its performance or its
                           ability to perform hereunder. During the existence of
                           this Manufacturing Agreement, King will provide
                           Mallinckrodt with a monthly report of its hydrocodone
                           bitartrate usage and availability, which report shall
                           be substantially in form attached hereto as Schedule
                           1(a).

                  (b)      The precise dosage forms to be manufactured by King
                           relative to the Current Products and the agreed upon
                           specifications for each (including, without
                           limitation, specifications for all components and raw
                           materials, whether active or inactive, in addition to
                           finished product specifications) are described on
                           Exhibit A attached hereto. As commercial production
                           becomes available with respect to each of the Future
                           Products, the specifications for each of the dosage
                           forms to be produced with respect thereto will be
                           attached to this Manufacturing Agreement as part of
                           Exhibit A. There will be no changes made to the
                           specifications set forth on Exhibit A except with the
                           mutual written agreement of the parties; provided
                           that, King will immediately implement any changes in
                           product specifications requested by Mallinckrodt if
                           any such changes are permissible under the provisions
                           of the appropriate ANDA or supplement thereto, as
                           appropriate. In the event any change in product
                           specifications requested by Mallinckrodt would cause
                           King to incur additional direct manufacturing cost in
                           production hereunder, King shall notify

                           Mallinckrodt writing, within ten (10) days after the
                           date of any requested specification change by
                           Mallinckrodt of the reason for and nature of any such
                           increased cost (as well as the timing anticipated for
                           any specification change) and if Mallinckrodt agrees
                           to pay such additional cost, King shall begin
                           implementation of any such requested specification
                           change at a time agreed upon by the parties; provided
                           that, it is understood that King shall not be
                           required to make any such specification change if
                           Mallinckrodt is unwilling to pay the cost therefor.
                           Notwithstanding the foregoing, the parties
                           acknowledge that it is possible that changes in
                           applicable laws, rules or regulations or actions of
                           the FDA, the DEA or any other regulatory agency may
                           require changes to be made in the agreed upon product
                           specifications. Should such an eventuality occur,
                           King will immediately notify Mallinckrodt in writing
                           of the nature of and reason for any such potential
                           specification changes and, subject to approval by
                           Mallinckrodt (which shall not unreasonably be
                           withheld), such changes will be implemented by King
                           as and when required (but not earlier than required)
                           and (i) any clearly demonstrable incremental direct
                           manufacturing cost increase occasioned thereby shall
                           be passed on to Mallinckrodt in the form of an upward
                           adjustment to the compensation to be paid to King
                           hereunder in accordance with Section 5 or (ii) any
                           clearly demonstrable incremental reduction in direct
                           manufacturing cost occasioned thereby shall be passed
                           on to Mallinckrodt in the form of a downward
                           adjustment to the compensation to be paid to King
                           hereunder in accordance with Section 5.

                  (c)      King will, in conjunction with its manufacturing
                           services provided hereunder, insure that all tablets
                           manufactured are properly and safely packaged, as
                           appropriate, in sample containers, 100, 500 or 1000
                           count bottles or bulk containers, all as reasonably
                           instructed by Mallinckrodt. King will provide all
                           tablet container/closure systems and other packaging
                           materials required by King to perform its obligations
                           hereunder; provided that, all container/closure
                           systems to be utilized for packaging of tablets shall
                           be in accordance with the appropriate ANDA, supported
                           by adequate

                           stability data and satisfactory to Mallinckrodt in
                           specification and actual quality.

                  (d)      Provided Mallinckrodt is in compliance with its
                           obligations under Section 5 hereof and its obligation
                           to supply Key Materials hereunder, all
                           work-in-process and finished goods produced in
                           accordance herewith shall be and remain at all times
                           the sole and exclusive property of Mallinckrodt. King
                           shall not mortgage, pledge, cause a lien to be
                           created with respect to or otherwise encumber any of
                           such work-in-process or finished goods, or take any
                           other action which is inconsistent with
                           Mallinckrodt's absolute right of ownership thereto,
                           other than the processing and handling of such
                           material in the performance of King's obligations
                           hereunder. Upon expiration or termination of this
                           Manufacturing Agreement, King shall immediately ship
                           to Mallinckrodt or to a location designated by
                           Mallinckrodt, at Mallinckrodt's expense, King's
                           entire inventory of finished goods produced hereunder
                           against payment therefor in accordance with the terms
                           hereof. Furthermore, upon expiration or termination
                           hereof, King shall finish, package and ship to
                           Mallinckrodt or to a location designated by
                           Mallinckrodt, at Mallinckrodt's expense, all
                           work-in-process as finished product against payment
                           therefor in accordance with the terms hereof, even if
                           the processing, packaging and shipping of such
                           work-in-process requires King to continue production
                           beyond the formal date of termination or expiration
                           of this Manufacturing Agreement.

                  (e)      Within three (3) months after the execution hereof,
                           and to the extent not already specifically provided
                           for herein, King and Mallinckrodt will work together
                           in good faith to establish intercompany procedures
                           and policies relative to the proper administration
                           and performance of this Manufacturing Agreement.

                  (f)      The parties agree that no part of this Manufacturing
                           Agreement is intended to give Mallinckrodt any
                           authority or input as to the daily operation of
                           King's manufacturing, laboratory, packaging and
                           distribution processes, especially but not
                           exclusively with regard to the number of King

                           employees involved with such processes. Mallinckrodt
                           shall not ask or suggest that King downsize its labor
                           force or lay of King employees in order to pass on to
                           Mallinckrodt an incremental cost savings nor will
                           Mallinckrodt ask, suggest or demand that King
                           purchase machinery or automated equipment which could
                           result in a reduction of King's labor force even if
                           the purchase of such machinery or automatic equipment
                           might result in King having reduced manufacturing or
                           packing costs. King agrees that it will not add any
                           cost to its provision of manufacturing services
                           hereunder except in good faith and as absolutely
                           required to carry out its obligations in accordance
                           herewith.

         2.       Raw Materials and Equipment.

                  (a)      Mallinckrodt agrees to provide to King, during the
                           term hereof, such amounts of Key Materials as King
                           shall require to satisfy its obligations hereunder to
                           Mallinckrodt to produce APAP/hydrocodone bitartrate
                           tablets hereunder. Mallinckrodt agrees to employ
                           reasonable commercial efforts to provide quantities
                           of the Key Materials to King. King agrees that under
                           no circumstances will King disclose to any third
                           party the quantities of Key Materials received and
                           processed by King hereunder, unless King is required
                           to do so by law or at the direction of a court or any
                           governmental (state or federal) agency or entity.
                           Mallinckrodt represents and warrants to King that
                           the Key Materials so provided will meet the
                           specifications set forth on Exhibit B attached
                           hereto. King agrees to test each lot of Key Materials
                           received from Mallinckrodt prior to use in any
                           production hereunder to determine definitively
                           whether it meets the applicable specifications. If
                           any lot does not meet specifications, King shall
                           inform Mallinckrodt of such fact immediately and in
                           writing and Mallinckrodt, if it is in agreement that
                           any such lot does not meet applicable specifications,
                           shall as soon as practicable provide King with a new
                           lot of Key Materials meeting applicable
                           specifications, which replacement is acknowledged by
                           King to be its only remedy for the failure of a lot
                           of Key Materials to meet applicable specifications.
                           If, within ten (10) business days of being informed
                           by King that any lot of Key Materials does not meet

<PAGE>   7



                           specifications, Mallinckrodt does not agree with
                           King that any lot of Key Materials fails to meet
                           applicable specifications, the parties will arrange
                           for the lot in question to be tested by a mutually
                           acceptable independent laboratory for conformity with
                           specifications and the determination of such
                           laboratory (unless clearly erroneous) will be final
                           and binding upon the parties. The cost of any such
                           testing by the independent laboratory shall be home
                           by the party whose judgment was incorrect. Any lots
                           of Key Materials not meeting applicable 
                           specifications shall, at the request of Mallinckrodt,
                           be destroyed by King or returned by King to
                           Mallinckrodt, in either case in the precise manner
                           specified by Mallinckrodt and at the expense of
                           Mallinckrodt. All Key Materials delivered to King in
                           accordance herewith shall be and remain at all times
                           the sole and exclusive property of Mallinckrodt. King
                           shall not mortgage, pledge, cause a lien to be
                           created with respect to or otherwise encumber any of
                           the Key Materials, or take any other action which is
                           inconsistent with Mallinckrodt's absolute right of
                           ownership thereto, other than the processing and
                           handling of the Key Materials in the performance of
                           King's obligations hereunder. Upon expiration or
                           termination of this Agreement, King shall
                           immediately return to Mallinckrodt or ship to a
                           location designated by Mallinckrodt, at
                           Mallinckrodt's expense, King's entire inventory of
                           unused Key materials.

                  (b)      King will manufacture APAP/hydrocodone bitartrate
                           tablets hereunder by utilizing the pieces of
                           equipment described on Exhibit C attached hereto (as
                           they are or will be described in the appropriate
                           ANDAs or supplements thereto). King shall have the
                           responsibility and shall incur the expense, with
                           respect to all pieces of equipment utilized for
                           production and testing hereunder, to ensure that all
                           calibration and normal operating maintenance on,
                           cleaning of, repair to and replacement of such
                           equipment is performed as and when necessary and that
                           all such equipment is protected from theft, fire or
                           other casualty of any sort. King shall maintain all
                           maintenance and repair records with respect to such
                           equipment in accordance with the requirements imposed
                           by cGMP.

                  (c)      With the exception of the Key Materials to be
                           provided by Mallinckrodt in accordance with
                           subsection (a) of this Section 2, all other raw
                           materials and other resources required in connection
                           with production hereunder shall be provided by King
                           at its cost and expense, subject to reimbursement in
                           accordance with the relevant provisions hereof
                           Mallinckrodt shall have the right to approve in
                           advance all suppliers of raw materials in connection
                           with production hereunder. King represents and
                           warrants to Mallinckrodt that it currently has access
                           to, and during the entire term thereof will make all
                           reasonable efforts to ensure that it will continue to
                           have access to, sufficient supplies of raw materials,
                           utilities, container/closure systems, packaging
                           materials and all other required items to perform the
                           services required of it hereunder without
                           interruption, subject only to the occurrence of any
                           events covered by the provisions of Section 15
                           hereof. King agrees that it will conduct audits of
                           its suppliers of raw materials hereunder on a regular
                           basis to ensure that such suppliers are producing raw
                           materials in accordance with all applicable laws,
                           rules and regulations (including without limitation
                           the requirements of cGMP) and to ensure that such
                           suppliers will continue to be able to supply a
                           sufficient quantity and quality of raw materials.
                           King will supply Mallinckrodt with copies of all such
                           supplier audit reports. King agrees, at all times
                           during the term hereof, to use all reasonable efforts
                           to maintain an inventory of raw materials (other than
                           Key Materials), packaging materials and
                           container/closure systems sufficient to manufacture
                           Mallinckrodt's outstanding Quarter Forecast (as
                           defined in Section 7(a) below) for finished product.
                           King agrees that, should it (i) receive any
                           notification (whether written or oral) from any
                           supplier of any raw materials or other resources to
                           be provided by King hereunder that such supplier 
                           either has the intention of discontinuing or
                           substantially reducing its supply of such raw
                           materials or other resources to King or (ii) become
                           aware of any facts or circumstances that make it
                           possible that there will be any shortage of any such
                           raw materials or resources or any other reason why
                           such raw materials or resources may be unavailable in
                           sufficient quantity or quality as and when needed,
                           then King shall promptly notify Mallinckrodt of the
                           nature of any such difficulty and shall keep
                           Mallinckrodt continuously

                           informed of any change in circumstances and of its
                           best efforts, which it shall make in good faith, to
                           locate alternate sources of supply for the affected
                           raw materials and resource (which alternate sources
                           shall be subject to prior approval by Mallinckrodt
                           but which approval shall not unreasonably be
                           withheld).

                  (d)      All Key Materials and other raw materials (including
                           container/closure systems) utilized by King in
                           production hereunder, as well as all work-in-process
                           and finished goods produced by King, shall be kept
                           physically and financially segregated by King from
                           its other properties and inventories and shall be
                           conspicuously marked as being the sole property of
                           Mallinckrodt. Key Materials, when and where
                           applicable, shall be stored, handled and used
                           hereunder in accordance with the requirements and
                           directives of the PDA and the DEA. Mallinckrodt
                           acknowledges that King will, during the existence of
                           this Manufacturing Agreement, purchase acetaminophen
                           and hydrocodone bitartrate from Mallinckrodt and
                           potentially other suppliers in order to manufacture
                           products other than the Current Products or Future
                           Products for third parties; provided, that such
                           manufacture for third parties will in no event be
                           accomplished by King in violation of Section 3.5 of
                           the Asset Purchase Agreement and, provided further
                           that, King will not utilize its DEA quota for
                           bydrocodone bitartrate for the manufacture of
                           products for any third parties unless and to the
                           extent that it has sufficient quota to meet all of
                           Mallinckrodt's requirements for finished goods
                           hereunder. Mallinckrodt will not make any claim of
                           ownership to any acetaminophen and hydrocodone
                           bitartrate purchased by King from Mallinckrodt (as
                           opposed to any Key Materials furnished hereunder by
                           Mallinckrodt's or from third parties as long as it is
                           intended for use other than for performance by King
                           under this Manufacturing Agreement.

                  (c)      King shall execute such financing statements,
                           security agreements and other documents that
                           Mallinckrodt, in its sole judgment, deems advisable
                           to protect any of its ownership interests in the Key
                           Materials, or any work-in-process or finished goods
                           and to carry out the purposes of this

                           Manufacturing Agreement. Mallinckrodt agrees that it
                           will pay the cost of preparing same and any recording
                           or filing fees payable in correction with the filing
                           or recording of a financing statement or similar 
                           document.

         3.       Laboratory Testing Services, Quality Control and Yields.

                  (a)      King will take all necessary steps to insure that it
                           has the equipment, instrumentation, resources and
                           trained personnel to provide all raw materials (other
                           than the Key Materials), in-process and product
                           assays, analysis and other testing as compliance with
                           cGP standards may require in connection with King's
                           production hereunder. Without limitation, King shall
                           provide a complete set of batch records, all
                           applicable deviation reports, out-of-specification
                           investigation reports and a complete certificate of
                           analysis for each lot of finished product produced
                           hereunder. Notwithstanding any other provision
                           hereof, and regardless of whether or not any
                           particular issue or detail is addressed by the terms
                           hereof, King shall at all times perform its
                           obligations hereunder in accordance with all
                           applicable cGMP standards.

                  (b)      King shall be responsible for all process, cleaning
                           and methods validation, stability studies (including,
                           without limitation, the production of quality
                           control finished product batches for each of the
                           Current Products and, when available, the Future
                           Products on at least an annual basis) or other tests
                           and procedures necessary for the manufacture and
                           release of finished product hereunder in accordance
                           with cGMP and in accordance with the requirements of
                           any ANDA (or any supplement thereto).

                  (c)      King agrees to conduct quality control sampling of
                           all raw materials, components, packaging materials
                           and container/closure systems purchased or furnished
                           by it promptly upon receipt of such materials and
                           systems and before use of any such materials and
                           systems in the production of finished goods
                           hereunder. King agrees that it will only utilize, in
                           connection with production hereunder, raw materials,
                           components, packaging materials and container/closure
                           systems that meet all applicable specifications and



                                       10
<PAGE>   11



                           that have been sampled, tested and approved in
                           accordance with King's normal test procedures and
                           standard operating procedures.

                  (d)      King shall maintain complete and accurate
                           documentation of all validation data, stability
                           testing data, batch records, quality control and
                           laboratory testing and any other data required under
                           cGMP, other FDA requirements or as otherwise
                           reasonably required by Mallinckrodt in connection
                           with King's production hereunder. King further agrees
                           to compile all data necessary for Mallinckrodt to
                           file an Annual Report and other periodic reports with
                           the FDA relative to the appropriate ANDAs or
                           supplements thereto concerning the Current Products
                           and the Future Products (as applicable), which data
                           shall be compiled in accordance with the requirements
                           of 21 CFR ss.314 and shall include, without
                           limitation, stability data, distribution data,
                           labeling, adverse reaction reports and data
                           concerning chemistry, manufacturing and control
                           changes. King agrees to conduct audits on a regular
                           basis with such frequency as Mallinckrodt may
                           reasonably direct to insure the integrity and
                           traceability of all data compiled by it to be
                           submitted in connection with or to be used in the
                           preparation of each Annual Report or other periodic
                           reports relative to each of the Current ANDAs and
                           Future ANDAs.

                  (e)      In accordance with Section 8(a) below, Mallinckrodt
                           shall have the sole right and responsibility for
                           approving or rejecting any shipment of finished
                           products produced by King hereunder. In order for
                           Mallinckrodt to discharge the aforesaid
                           responsibility, King shall quarantine every lot of
                           finished product in accordance with Mallinckrodt
                           approved quarantine procedures until King receives
                           approval from Mallinckrodt's quality assurance 
                           function for release of any such lot of finished
                           product, which approval (or not, as the case may be)
                           shall be provided by Mallinckrodt as quickly as
                           possible, but in no event later than ten (10)
                           calendar days from the date of King's initial quality
                           assurance release of finished product (which release
                           is accompanied by appropriate documentation) into
                           Mallinckrodt's quality assurance function. King will
                           audit all batch records with respect to any
                           particular lot of finished products in




                                       11
<PAGE>   12



                           accordance with Mallinckrodt approved procedures and
                           will provide Mallinckrodt's quality assurance
                           function with a complete set of all batch records (to
                           include all deviation and out-of-specification
                           investigation reports) with respect to such lot. In
                           particular, with respect to each lot of finished
                           goods produced hereunder, Mallinckrodt shall receive
                           from King a certificate of compliance (in a form and
                           executed by an individual reasonably satisfactory to
                           Mallinckrodt) stating that such lot of finished
                           products has been manufactured in accordance with
                           cGMP. King and Mallinckrodt will both take whatever
                           actions are necessary to ensure that all
                           discrepancies, problems or issues raised during the
                           batch record audit process are resolved as
                           expeditiously as possible prior to release from
                           quarantine of any lot of finished product.

                  (f)      King guarantees to Mallinckrodt that it will employ
                           all possible efforts during the term hereof to
                           maximize yields of finished product. King
                           guarantees specifically to Mallinckrodt that each lot
                           of finished product produced hereunder will meet the
                           yield level for the particular strength in question
                           as set forth on Exhibit D, hereinafter with respect
                           to any particular dosage strength known as the "Yield
                           Guarantee Level." In the event that, with respect to
                           any lot or production run made and invoiced by King
                           in accordance with this Agreement, the actual yield
                           of finished product does not meet the Yield Guarantee
                           Level, there will be an adjustment in the 
                           compensation payable to King hereunder as set forth
                           in Section 5 below.

                  (g)      Yield calculations and testing shall be made by King
                           for each volume of finished product made by King in a
                           production run in accordance with the methods for
                           determining product yield set forth on Exhibit E
                           attached hereto, and prior to release of the finished
                           product for shipment. Any such yield calculations for
                           a particular lot of finished product shall be
                           included on the invoice sent to Mallinckrodt covering
                           such finished product. Mallinckrodt may, at any time
                           within thirty (30) days after the release date for
                           any particular volume of finished product, make its
                           own calculations and tests of product yield in
                           accordance with the methods set

<PAGE>   13



                           forth on Exhibit E. In the event such calculation and
                           testing by Mallinckrodt indicates that there is a
                           discrepancy between the determination of actual yield
                           between Mallinckrodt and King, the parties shall
                           settle the differences among themselves or jointly
                           perform another test and calculation of product yield
                           through a mutually agreeable independent laboratory,
                           the results of which test shall be determinative. The
                           costs of any testing by an independent laboratory as
                           aforesaid shall be borne by the party whose rest
                           results were furthest from the result obtained by
                           such independent laboratory.

         4.       Labeling and Product Literature.

                  (a)      King agrees to affix labels to all finished product
                           in accordance with Mallinckrodt's instructions unless
                           to do so would violate any state or federal statute
                           or regulation or would not conform to cGMP standards.
                           Until such time as Mallinckrodt otherwise directs,
                           King, at its expenses but subject to reimbursement
                           in accordance with the appropriate provisions of
                           Section 5 below, will be responsible for the printing
                           of package inserts and labels for all finished
                           products, King shall affix the appropriate lot number
                           and expiration date to each label that is placed on a
                           bottle or package of finished product. King will not
                           change or alter in any manner any product labeling
                           without the prior written consent of Mallinckrodt,
                           and it is understood that except as specifically
                           provided herein Mallinckrodt will be solely
                           responsible for the substantive content of all
                           labels. King shall maintain a system to ensure label
                           accountability and shall provide Mallinckrodt with an
                           inventory reconciliation of labels as often and in
                           such form as Mallinckrodt may reasonably require; in
                           no event shall King be required to provide such
                           reconciliation more than twice per calendar quarter
                           but such reconciliation shall be provided by King no
                           less often than quarterly and, in any case when
                           provided, such reconciliation shall be given to
                           Mallinckrodt no later than fifteen (15) days after
                           the end of any three (3) month period hereunder for
                           which such an inventory reconciliation is being
                           provided.

                  (b)      Mallinckrodt will have sole responsibility, at its
                           expense, for the production of all material safety
                           data sheets, product bulletins and other product
                           literature relative lo the Current Products or the
                           failure Products. However, King agrees at all times
                           during the term hereof to provide Mallinckrodt with
                           any and all information in its knowledge or
                           possession that Mallinckrodt might find useful or
                           relevant in the preparation of any such product
                           literature, as and when King becomes aware of such
                           information provided that, it is understood that
                           King has no affirmative obligation whatsoever to
                           search for any such information.

                  (c)      Mallinckrodt agrees that it will not engage in any
                           act which causes any packaged and labeled finished
                           product produced by King to become adulterated or
                           misbranded within the meaning of the federal Food,
                           Drug and Cosmetic Act, as amended.

         5.       Compensation for Services Performed by King.

                  (a)      In return for the performance by King of the services
                           specified herein, Mallinckrodt agrees to pay King a
                           processing fee of Five Thousand Dollars ($5,000) per
                           batch of finished product in tablet form ("Tolling
                           Fee") (appropriately tested, bottled and labeled and
                           otherwise produced in accordance with the
                           requirements hereof, especially Sections 1, 2, 3 and
                           4 above), subject to adjustment hereunder due to its
                           failure to meet the Yield Guarantee Level. For
                           purposes of the immediately preceding sentence and
                           this Manufacturing Agreement, the term "batch"
                           assumes a production run of one million (1,000,000)
                           tablets (one million two hundred thousand (1,200,000)
                           for any dosage formulations having a strength of 5
                           mg. of hydrocodone bitartrate and 500 mg. of APAP).
                           In addition to the Tolling Fee described immediately
                           above, Mallinckrodt shall also pay King its direct
                           manufacturing costs associated with production
                           hereunder. The Tolling Fee and the direct
                           manufacturing costs associated therewith with respect
                           to any particular volume of finished product produced
                           by King hereunder shall be due and payable to King
                           within forty five (45) days after receipt by
                           Mallinckroddt of an invoice from King (and other

                           appropriate documentation as may be agreed)
                           indicating the Tolling Fees payable, the direct
                           manufacturing cost associated with the production
                           lots for which the invoice is being submitted the
                           number of batches and total number of tablets
                           produced, the number of kilograms of APAP and
                           hydrocodone bitartrate used in the finished product
                           being invoiced, the lot numbers of products produced
                           and the release date for each of those lots, and
                           certifying that the finished product for which
                           Mallinckrodt is being billed has been produced
                           finished in conformance with applicable
                           specifications, cGMP and the requirements hereof
                           (including without limitation that each batch
                           produced meets the Yield Guarantee Level or, if such
                           is the case, that any one or more batches invoiced
                           fails to meet the Yield Guarantee Level providing
                           specific details in that case as to the actual yield
                           achieved for each batch included in the invoiced
                           batch or batches) and is ready for release and
                           shipment.

                  (b)      The Tolling Fee set forth above in subsection (a)
                           above shall remain firm until January 1, 1997 and
                           shall automatically be adjusted for each calendar
                           year thereafter, effective for orders delivered on or
                           after tile first day of January of each such calendar
                           year, to reflect increases or decreases in the
                           Producer Price Index as published by the
                           International Monetary Fund for the calendar year
                           prior to the year for which any such adjustment is to
                           take place.

                  (c)      In the event that, with respect to any batch or
                           batches made and invoiced by King in accordance with
                           this Manufacturing Agreement, the actual yield of any
                           finished product batch invoiced is less than the
                           appropriate Yield Guarantee Level, the Tolling Fee
                           paid or payable with respect to such batch of
                           finished product shall be adjusted downward by the
                           amount set forth on Exhibit F hereto.

                  (d)      In the event that application of the provisions set
                           forth in subsection (c) immediately above indicates
                           that a downward adjustment in the Tolling Fee is
                           required with respect to any particular volume of
                           finished product, King shall (i) if payment of the
                           Tolling Fee for such volume has already

                           been made, promptly refund the appropriate amount to
                           Mallinckrodt in cash or, if Mallinckrodt approves,
                           credit any such amount against future payments by
                           Mallinckrodt hereunder or, (ii) if payment of the
                           Toiling Fee for such volume has not been made, issue
                           a corrected invoice to Mallinckrodt for the
                           appropriate amount payable to King.

                  (e)      Notwithstanding any other provision hereof, in the
                           event that as a consequence of any negligent action
                           or omission to act by King in the course of the
                           performance of its obligations hereunder all or any
                           portion of any batch, lot or other volume of Key
                           Materials is destroyed or otherwise rendered unusable
                           for the production of finished product hereunder,
                           then King (in addition to any adjustments to be made
                           to the Tolling Fee in accordance with this Section 5)
                           will pay to Mallinckrodt, within third (30) days of
                           the date of any request for payment by Mallinckrodt,
                           an amount equal to the average amount charged by
                           Mallinckrodt to other consumers of Key Materials for
                           an amount of such Key Materials equal to the volume
                           of Key Materials so destroyed or otherwise rendered
                           unusable, less fifteen Accent (l5%). Furthermore, it
                           is understood that King shall be responsible for and
                           Mallinckrodt notwithstanding any other provisions
                           hereof, shall have no responsibility or liability to
                           make payment for any batch or lot of finished
                           products that, through no act or omission to act on
                           the part of Mallinckrodt, fails to meet applicable
                           specifications, is the subject of a recall (whether
                           voluntary or involuntary), is not merchantable or fit
                           for its intended purposes or is adulterated or
                           misbranded. At Mallinckrodt's option all or any
                           portion of the amount King owes Mallinckrodt at any
                           given time pursuant to this subsection (e) may be
                           offset by Mallinckrodt against any Tolling Fee that
                           may be due to King hereunder, provided that in any
                           case where Mallinckrodt decides to exercise such
                           option it will give notice thereof to King.

                  (f)      At all times during its performance hereunder, King
                           shall take whatever actions are reasonably available
                           to it to ensure that any increases in its direct
                           manufacturing cost applicable to such performance are
                           kept to an absolute minimum. King will at all times
                           keep Mallinckrodt fully

                           direct manufacturing cost hereunder and will consult
                           with and seek Mallinckrodt's input concerning
                           the various courses of action or alternatives that
                           might be adopted to reduce, slow or prevent the
                           increase of any such cost.

         6.       Minimum Manufacturing Fee.

                  (a)      Regardless of the amount of finished product that
                           Mallinckrodt requests King to produce during any
                           contract year during the initial term hereof and
                           provided that King is in compliance with its
                           obligations and the terms and conditions hereof,
                           Mallinckrodt hereby agrees to pay King a minimum fee
                           for each contract year ("Minimum Manufacturing Fee")
                           during such initial term as follows:

                           be reduced dollar-for-dollar in any given contract
                           year by the cumulative amount of (i) any and all
                           downward adjustments in Tolling Fees for batches
                           produced during such contract year that are made in
                           accordance with the provisions of subsection (c) of
                           Section 5 above, (ii) any amounts payable by King to
                           Mallinckrodt pursuant to subsection (e) of Section 5
                           above and (iii) any amounts payable by King to
                           Mallinckrodt pursuant to subsections (a) or (d) of
                           Section 8 below.

                  (c)      Mallinckrodt agrees that if, for any given contract
                           year, Mallinckrodt has not requested King to produce
                           and King has not produced finished product in an
                           amount that, given the applicable Tolling Fee, would
                           provide King with payment (over and above
                           reimbursement for direct manufacturing costs) equal
                           to or in excess of the Minimum Manufacturing Fee for
                           that contract year, as adjusted pursuant to the
                           provisions of subsection (b) set forth immediately
                           above (the amount by which such payment is less than
                           the applicable Minimum manufacturing Fee to be
                           referred to herein as the "Minimum Manufacturing Fee
                           Shortfall"), Mallinckrodt shall either, at its
                           option, (i) make payment to King of the Minimum
                           Manufacturing Fee Shortfall within thirty (30)
                           days after the date on which it receives a correct
                           invoice from King setting forth the amount of any
                           such Minimum Manufacturing Fee Shortfall for the
                           contract year in question, or (ii) place an order
                           with King for the production of that amount of
                           finished product that would generate Tolling Fees
                           (assenting no downward adjustments pursuant to the
                           applicable provisions of Section 5) equal to or
                           greater than the Minimum Manufacturing Fee Shortfall.
                           In the event Mallinckrodt selects the latter option,
                           Mallinckrodt will provide King with the necessary
                           quantity of Key Materials to complete the processing
                           of such order and will make payment to King for the
                           production of such finished product in accordance
                           with procedures established in this Manufacturing
                           Agreement.

                           its total anticipated monthly requirement for
                           finished product during the following twelve (12)

                           and other information available to Mallinckrodt, but
                           under no circumstances whatsoever shall any forecasts
                           made hereunder be deemed to be an order for the
                           production of finished goods or otherwise binding on
                           Mallinckrodt.

                  (b)      Finished product shall be ordered by Mallinckrodt
                           only in writing. King is not entitled to accept

         8.       Acceptance, Rejection and Results.

                  (a)      If Mallinckrodt reasonably determines that any
                           finished product (whether in its possession or in the
                           possession of any distributor or customer) is
                           defective in material or workmanship, not in
                           conformance with applicable specifications, is
                           adulterated or misbranded, or is otherwise not in
                           compliance with the requirements of any of the ANDAs
                           (or supplements thereto) relating to the Current
                           Products or the Future Products (as applicable) or of
                           this Manufacturing Agreement, then Mallinckrodt at
                           its sole option and in addition to any other rights
                           it may have under this Manufacturing Agreement or
                           otherwise, may reject and return (either on behalf of
                           itself or on behalf of its customers and
                           distributors) any such finished products to King for
                           repackaging or disposal at King's expense. At the
                           time of any such rejection, Mallinckrodt shall
                           provide King with a written notice describing in
                           detail the circumstances surrounding the rejection
                           and Mallinckrodt's reasons therefor (with specific
                           reference to sections hereof as appropriate).
                           Mallinckrodt may reject such finished goods and
                           either return them to King or destroy or dispose of
                           them in the least expensive and most environmentally
                           sound manner and King shall be responsible for the
                           costs of any such return, destruction or disposal.
                           The amount already paid by Mallinckrodt to King
                           pursuant to Section 5 hereof for any finished goods
                           that are returned, destroyed or disposed of in
                           accordance herewith shall be refunded by King to
                           Mallinckrodt immediately upon written request from
                           Mallinckrodt and, in addition, King shall pay to
                           Mallinckrodt, to reimburse it for the loss of Key
                           Materials in connection with any such finished goods,
                           an amount equal to the amount payable to
                           Mallinckrodt for Key Materials pursuant to the first
                           sentence of Section 5(e) above. Notwithstanding the
                           preceding portions of this subsection (a), in the
                           event that King does not agree with Mallinckrodt that
                           any rejection and return of product by Mallinckrodt
                           is appropriate under the teens hereof, then, if such
                           disagreement cannot be resolved by the parties it
                           shall be referred by them to a mutually acceptable
                           independent consultant for determination as to
                           whether Mallinckrodt had a reasonable basis for
                           rejecting and returning the goods in question. If the



                                       20
<PAGE>   21





                           consultant determines that Mallinckrodt had no such
                           reasonable basis, then Mallinckrodt shall reimburse
                           King for the costs incurred by King in connection
                           with any such rejection and return. It is agreed that
                           in no event will King have the right to refuse the
                           rejection and return of finished product and that
                           King will only have the right to financial
                           reimbursement after the fact if and when it is
                           determined in accordance with the procedure outlined
                           immediately above that such rejection and return was
                           improper.

                  (b)      Any finished product received by Mallinckrodt, or by
                           its distributors or customers (if shipped directly to
                           either of then by King), from King that has not been
                           rejected by Mallinckrodt within sixty (60) days after
                           receipt or within thirty (30) days after the date on
                           which the recipient first became aware or should have
                           become aware of a basis for rejection, whichever
                           occurs later, shall be deemed to have been accepted.

                  (c)      If Mallinckrodt reasonably decides to or is required
                           to initiate a product recall, withdrawal or field
                           correction with respect to, or if there is any
                           governmental seizure of, any finished product
                           manufactured hereunder which action is due, in whole
                           or in part, to (i) a failure of any lot of finished
                           product manufactured by King hereunder to conform to
                           applicable specifications (including, without
                           limitation, it being adulterated or misbranded),
                           required manufacturing processes, the requirements of
                           the appropriate ANDA (or supplement thereto) or any
                           warranty or other requirement set forth in this
                           Manufacturing Agreement, (ii) the failure by King to
                           comply in all respects with any applicable law, rule,
                           regulation, standard, court order or decree or (iii)
                           the negligent or intentional wrongful act or omission
                           of King, Mallinckrodt will notify King promptly of
                           the details regarding such action, including
                           providing copies of all relevant documentation
                           concerning such action. King will assist Mallinckrodt
                           in investigating any such situation, if Mallinckrodt
                           so requests, but all regulatory contacts that are
                           made and all activities concerning seizure, recall,
                           withdrawal or field correction will be initiated and
                           coordinated by Mallinckrodt, in accordance with
                           intercompany

                           parties in accordance with Section 1(e) above.

                  (d)      If any such recall, withdrawal, field correction or
                           seizure occurs due solely to (i) a failure of any lot
                           or batch of finished product manufactured by King
                           hereunder to conform to applicable specifications
                           (including, without limitation, it being adulterated
                           or misbranded), required manufacturing processes, the
                           requirements of the appropriate Current ANDA or
                           future ANDA or any warranty or other requirement set
                           forth in this manufacturing Agreement, (ii) the
                           failure by King to comply in all respects with any
                           applicable law, rule, regulation, standard, court
                           order or decree or (iii) the negligent or intentional
                           wrongful act or omission of King, then King shall
                           bear the full cost and expense of any such seizure,
                           recall, withdrawal or field correction, including
                           without limitation finished product replacement to
                           the market from which there was a seizure, recall,
                           withdrawal or field correction and any and all third

                           connection with the recall process. If both King and
                           Mallinckrodt contribute to the cause of a seizure,
                           recall, withdrawal or field correction, the cost and
                           expenses thereof will be shared in proportion to each

                  standard operating procedures available to Mallinckrodt for
                  review upon request. King agrees to make such changes in its
                  standard operating procedures, to the extent they are utilized
                  in connection with King's performance hereunder, as
                  Mallinckrodt shall from time to time reasonably request,
                  provided that Mallinckrodt agrees to pay King for any

         of the King Business and will, in addition, agree to take or refrain
         from taking certain actions in connection with the King Business, as
         follows:

         (a)      Within ninety (90) days after the end of each fiscal year,
                  King shall provide to Mallinckrodt a statement of financial
                  condition of King for the previous fiscal year, including a
                  balance sheet and statement of earnings for such year,
                  certified as accurate by the chief executive and chief
                  financial officers of King, prepared in accordance with
                  generally accepted accounting principles on a basis consistent
                  with past practices.

         (b)      King will provide written notice to Mallinckrodt, as soon as
                  reasonably practicable and in any event within fifteen (15)
                  days after it acquires knowledge, of the commencement of, or
                  material threat of the commencement of, any action, suit or
                  proceeding, brought by any party (private or governmental),
                  before any court, arbitrator, commission or governmental body,
                  agency or official which may have an adverse effect on the
                  ANDA Business or King's continued performance hereunder. In
                  connection with any such notice King shall provide to
                  Mallinckrodt a description of the nature of any such pending
                  or threatened action as well as such other information as
                  Mallinckrodt may reasonably request.

         (c)      King will do all things necessary or appropriate to maintain
                  the value and usefulness of the Bristol Facility and all its
                  other assets and properties. King will keep the Bristol
                  Facility and all of its tangible property in good working
                  order and condition, ordinary wear and tear excepted, subject
                  to the dictates of commercial necessity and sound business
                  practice. King will maintain insurance on its properties in at
                  least such amounts and against at least such risks as are
                  usually insured against by companies of established repute
                  engaged in the same or similar business, including without
                  limitation (i) product liability insurance with limits of Ten
                  Million Dollars ($10,000,000) per occurrence and Ten Million
                  Dollars ($10,000,000) in the aggregate and with an appropriate
                  endorsement naming Mallinckrodt as an additional insured
                  party, (ii) insurance covering loss or damage with respect to
                  any Key Materials, work-in-process or


                                       29

<PAGE>   30



                  finished product inventory in King's possession with an
                  appropriate endorsement naming Mallinckrodt as an additional
                  insured party, (iii) insurance on the Bristol facility and on
                  each and every item of equipment to be used in connection with
                  production hereunder within limits of Twenty Million Dollars
                  ($20,000,000) for the building and Six Million Dollars
                  ($6,000,000) for the equipment and (iv) a policy of insurance
                  for business interruption insuring all of King's business
                  activities, including without limitation the ANDA Business,
                  against all such risks as are ordinarily and normally insured
                  against under such policies.

         (d)      King will continue to engage in business of the same general
                  type as the King Business and will preserve, renew and keep
                  in full force and effect its corporate existence and take all
                  action reasonably necessary to maintain its rights, privileges
                  and permits (including any regulatory permits) necessary or
                  desirable in the normal conduct of business.

         (e)      Unless Mallinckrodt gives King its written consent (which
                  consent shall not, without business reason to Mallinckrodt, be
                  withheld) King will not engage in any transaction whereby it
                  (i) merges with any other person, firm or entity, (ii) sells
                  all, substantially all or a substantial portion of its assets
                  to any person, firm or entity, (iii) sells a controlling
                  interest in its voting securities to any person, firm or
                  entity, (iv) sells, leases or otherwise disposes of its
                  ownership of or control over the Bristol Facility or (v)
                  otherwise engages in a transaction that will have as its
                  intent or effect any change of ownership or control of King or
                  of the nature or character of King's business.

         (f)      As of a date thirty (30) days after the receipt by King of its
                  audited annual financial statements and thereafter, King shall
                  maintain stockholders' equity, as reported on King's annual
                  audited balance sheet, equal to or in excess of Twelve Million
                  Dollars ($12,000,000).

         (g)      King shall maintain a debt to equity ratio of no greater than
                  two and one half to one (2.5/1). For purposes hereof, "debt"
                  shall include, without


                                       30




<PAGE>   31



                  limitation, all amounts payable under lines of credit, all
                  term financing from banks or financial institutions, all
                  notes payable, the current portion of long-term debt, and
                  long-term debt, and any other items normally denominated as
                  debt, all as reported on King's annual audited balance sheet.
                  For purposes hereof, "equity" shall mean stockholders' equity
                  as reported on King's annual audited balance sheet, as
                  adjusted for any changes in accounting practices subsequent to
                  December 31, 1994. In particular, without limitation, equity
                  shall be adjusted downward for the after tax cost of
                  development of ANDAs if such costs are recorded as an asset on
                  King's annual audited balance sheet.

         (h)      King will not create, assume or suffer to exist on any of its
                  assets used in any manner in connection with King's
                  performance hereunder any mortgage, lien, pledge, security
                  interest or encumbrance of any kind, except for (i) liens for
                  current taxes not yet due, (ii) those existing liens set forth
                  on Exhibit G attached hereto, and (iii) leases for equipment
                  to be used in connection with the King Business for
                  manufacturing, development, analytical and general office
                  management purposes. Within thirty (30) days after the Closing
                  Date, King will pay completely its obligations under that
                  certain term loan granted to King by First Union Bank as
                  described on Exhibit G hereto.

         (i)      King will not dividend to its shareholders any cash, assets or
                  other property except to the extent that any such dividends
                  would not have the effect of causing King to be in default
                  under either subsections (f) or (g) set forth above in this
                  Section 11.

         (j)      King will, as expeditiously as possible after the Closing
                  Date, use all possible efforts to make the corrections,
                  improvements and changes relative to manufacture of
                  APAP/hydrocodone bitartrate dosage forms that are set forth on
                  Exhibit H attached hereto. Once every year during the
                  existence of this Manufacturing Agreement, on or about the
                  anniversary of the date hereof, Mallinckrodt may conduct an
                  audit of King (i) to ensure that there has been compliance by
                  King with the requirements of this


                                       31




<PAGE>   32



                  subsection (j) and (ii) to discuss what additional
                  corrections, improvements and changes might be made during the
                  year following any such audit.

12.      Access and Audit.

         (a)      In addition to any rights Mallinckrodt may have pursuant to
                  Section 11(j) set forth above, Mallinckrodt, through its
                  employees, consultants or other representatives, will have the
                  right during normal business hours and upon fifteen (15) days
                  advance arrangement with King to inspect and audit King's
                  operations at the Bristol Facility to determine whether or not
                  King is complying in all respects with any of its obligations
                  hereunder. Mallinckrodt warrants that all such inspections and
                  audits shall be carried out in a manner calculated not to
                  unreasonably interfere with King's conduct of business at the
                  Bristol Facility and to insure the continued confidentiality
                  of King's other business and technical information. Further,
                  Mallinckrodt agrees to comply with all of King's safety and
                  security requirements during any visits to the Bristol
                  Facility.

         (b)      Upon at least fifteen (15) days advance notice, appropriate
                  employees or representatives of Mallinckrodt shall have the
                  right, periodically but no more often than quarterly, to audit
                  the books and records of King that relate in any fashion to
                  the provision by King of services hereunder or the rights of
                  Mallinckrodt hereunder. King will provide copies (at a minimal
                  charge) of all relevant documentation and appropriate King
                  personnel will be made available to answer questions and
                  provide information in connection with any such audit.

13.      Ownership of Technology.

         King acknowledges that, pursuant to the Asset Purchase Agreement of
         even date herewith, Mallinckrodt owns all right, title and interest in
         and to the Current Products and the Future Products. King further
         acknowledges that Mallinckrodt will become the owner of all right,
         title and interest in and to all technology, know-how, inventions,
         discoveries, ideas, innovations, concepts, information or


                                       32


<PAGE>   33



         data, whether patentable or not, which results from the production of
         finished product hereunder ("Proprietary Information"). Upon the
         termination or expiration of this Manufacturing Agreement or upon
         Mallinckrodt's request at any time, King agrees to deliver to
         Mallinckrodt any and all documents or information relating to the
         Proprietary Information and King further agrees, during the term
         hereof, to keep Mallinckrodt apprised in writing of the nature of any
         Proprietary Information that is developed as and when this occurs.

14.      Warranties of Mallinckrodt.

         (a)      Mallinckrodt warrants to King that the Key Materials furnished
                  by Mallinckrodt hereunder will meet the specifications set
                  forth on Exhibit B attached hereto. In the event any lot of
                  Key Materials is not in conformance with applicable
                  specifications, King will give immediate written notice of the
                  nature of any such defect to Mallinckrodt and will furnish a
                  sample of any defective material to Mallinckrodt by the
                  fastest possible means. Mallinckrodt shall replace, at its own
                  expense, any lot of Key Materials that does not meet
                  applicable specifications, and shall reimburse King for its
                  actual, out-of-pocket costs in handling such material, but in
                  no event shall Mallinckrodt be liable to King for the payment
                  of special, incidental, indirect or consequential damages,
                  even if advised of the possibility of such damages. It shall
                  be a condition of Mallinckrodt's obligation to reimburse King
                  hereunder that Mallinckrodt receive complete documentation
                  proving the nature and amount of out-of-pocket costs incurred
                  by King. Notwithstanding any other provision hereof,
                  Mallinckrodt makes no representation or warranty of any kind,
                  express or implied, as to the merchantability, fitness for a
                  particular purpose or as to any other matter with respect to
                  the Key Materials, whether used alone or in combination with
                  any other material.

         (b)      Mallinckrodt represents, warrants and guarantees to King that
                  Key Materials furnished to King hereunder are not, or will not
                  be (as appropriate):

                           municipal law in which the definitions of
                           adulteration and misbranding are substantially
                           identical with those contained in the federal Food,
                           Drug and Cosmetic Act, or articles which may not
                           under the provisions of Sections 404 or 505 of said
                           Act be introduced into interstate commerce or which
                           may not under substantially similar provision of any

                           (commercial or otherwise), judgment, order or decree
                           to which Mallinckrodt is a party.

15.      Force Majeure.

         Neither party to this Manufacturing Agreement shall be liable for or be
         in breach of any provision hereof for any failure or delay on its part
         to perform any obligation (other than the obligation to make payments
         when due) under any provision of this Manufacturing Agreement because
         of an event of "force majeure", including, but not limited to, any act
         of God, fire, flood, explosion, unusually severe weather, war,
         insurrection, riot, sabotage, or any other cause whatsoever, whether
         similar or dissimilar to those enumerated herein, beyond any
         possibility of control of such party, if and only if the party affected
         shall have used all possible efforts under the circumstances to avoid
         such occurrence and to remedy it promptly if it shall have occurred
         and, further, if and only if any such occurrence is not the result of
         any failure by a party to perform fully its obligations hereunder which
         failure is not itself caused by an event of "force majeure."
         Notwithstanding the immediately preceding sentence, the occurrence of
         an event of "force majeure" shall have no effect whatsoever on the
         obligations or responsibilities of King under and pursuant to the terms
         of Sections 4.1(b) and 4.1(c) of the Asset Purchase Agreement or any
         other provision thereof placing upon King any liability, obligation or
         responsibility. Without prejudice to or effect upon Mallinckrodt's
         rights under the Asset Purchase Agreement, if an event of force
         majeure in any given contract year causes a failure or delay in
         performance hereunder by King for more than thirty (30) continuous days
         during any given contract year, Mallinckrodt, at its option, may (i)
         reduce the total quantity of finished product to be manufactured and
         delivered hereunder and the Minimum Manufacturing Fee otherwise due
         hereunder equitably and proportional (A) to the amount of time during
         such year that performance has been prevented by the event of force
         majeure and (B) to the extent of deliveries or performance not made or
         not accepted as a result of such event of force majeure or (ii) may, at
         its option extend the delivery or performance period by the amount of
         time during which such delivery or performance was omitted or delayed.

16.      Relationship of Parties.

         For all purposes hereof, King shall be deemed to be an independent
         contractor and this Manufacturing Agreement shall not create an agency,
         partnership, joint venture, or employer/employee relationship, and
         nothing hereunder shall be deemed to authorize either party to act for,
         represent or bind the other or any of its affiliates except as
         expressly provided in this Manufacturing Agreement.

17.      Confidentiality.

         (a)      King and Mallinckrodt shall maintain in confidence and not use
                  or disclose to any third party, except as is specifically
                  contemplated herein or is otherwise necessary to perform their
                  respective obligations under this Manufacturing Agreement, and
                  then only on a confidential basis satisfactory to both
                  parties, any information, including without limitation
                  business and technical information, experience or data
                  regarding any facility, programs, laboratories, processes,
                  products, costs, equipment operation or customers, relating to
                  the manufacture or sale of finished product hereunder; in
                  particular, but without limitation, the aforestated obligation
                  of confidentiality as it relates to King applies to the
                  Proprietary Information as defined in Section 13 hereof and
                  the aforestated obligation of confidentiality as it relates to
                  Mallinckrodt applies to information concerning the Bristol
                  Facility and the King Business. The foregoing obligations of
                  confidentiality and non-use shall survive the termination or
                  expiration of this Manufacturing Agreement for a period of
                  five (5) years. Nothing herein shall prevent either party from
                  disclosing any information required by statute or governmental
                  regulations to be disclosed in a judicial or administrative
                  proceeding after all reasonable legal remedies for maintaining
                  such information in confidence have been practically exhausted
                  or from using information which (i) has been published or has
                  become part of the public domain other than by acts, omissions
                  or fault of such party, (ii) was lawfully received by such
                  party from a third party free of any obligation of confidence
                  to such third party, (iii) or a party can demonstrate from its
                  records was already in its possession prior to receipt

                  thereof, directly or indirectly, from the other party. The
                  party asserting the applicability of one of the exclusions
                  from the obligation of confidentiality set forth in the
                  immediately preceding sentence shall have the burden of
                  proving the applicability of any such exclusion in any
                  particular circumstance.

         (b)      Each party acknowledges that any breach by it of the
                  confidentiality obligations set forth in this Section 17 would
                  cause the other party irreparable harm for which compensation
                  by monetary damages would be inadequate and, therefore, the
                  party that has been harmed by any such breach shall have the
                  right to an injunction or decree for specific performance, in
                  addition to any other rights and remedies such party may have
                  at law or in equity.

18.      Indemnification.

         (a)      King hereby agrees to indemnify, defend and hold harmless
                  Mallinckrodt and its affiliates from and against any and all

                  losses, damages, injuries, liabilities, costs and expenses,
                  including without limitation, interest, penalties and
                  reasonable attorneys' fees and expenses (collectively
                  "Damages") asserted against, resulting to, imposed upon or
                  incurred by Mallinckrodt or its affiliates, directly or
                  indirectly related to, arising out of or resulting from:

                  (i)      any breach or failure of any of the representations,
                           warranties and covenants of King contained herein,
                           including (without limitation) any breach or failure
                           by King to perform any obligation contained herein,
                           including without limitation the production of
                           finished product hereunder strictly in accordance
                           with the requirements of the applicable ANDAs (or
                           supplements thereto), applicable cGMP requirements,
                           applicable laws, rules and regulations (including
                           without limitation FDA and DEA rules and regulations)
                           and any other requirements set forth herein,

<PAGE>   38



                  (ii)     any failure of King, or anyone acting on behalf of
                           King, to observe or comply with any applicable
                           laws, rules or regulations related in any fashion
                           to King's performance hereunder, including without
                           limitation the handling or disposal of any materials
                           or wastes generated by King in connection with its
                           performance hereunder,

                  (iii)    any imposition of liability or notice of
                           responsibility issued by any federal, state or local
                           authority related to the handling or disposal of any
                           materials or wastes used or generated by King in
                           connection with its performance hereunder,

                  (iv)     the use or handling of the finished product produced
                           hereunder, except to the extent that any Damages are
                           caused by the failure of Key Materials supplied by
                           Mallinckrodt to meet applicable specifications or
                           otherwise caused by the Key Materials,

                  (v)      any claim, notice or governmental action affecting
                           King or the Bristol Facility, including without
                           limitation any requirement for action or the payment
                           of monies to remediate any environmental condition at
                           the Bristol Facility, and

                  (vi)     any Damages arising as a consequence of any of the
                           following:

                           (A)      a recall, withdrawal or suspension of any
                                    product registration, product license,
                                    manufacturing license (e.g. an NDA or ANDA),
                                    or other governmental license, approval or
                                    consent with respect to any products
                                    manufactured under this Manufacturing
                                    Agreement,

                           (B)      any injunction or other order issued by any
                                    court of appropriate jurisdiction which
                                    requires King or Mallinckrodt to recall
                                    products manufactured under this
                                    Manufacturing Agreement or requires King to
                                    suspend its operations pending further
                                    approval or authorization from

                                    a governmental official or agency or which
                                    otherwise has a material adverse effect on
                                    King's performance hereunder, or

                           (C)      King, or any of its employees or affiliates,
                                    is debarred under relevant sections of the
                                    federal Food, Drug and Cosmetic Act or is
                                    convicted of or formally charged with a
                                    criminal offense relating to the development
                                    or approval process or the manufacture or
                                    sale of any drug or pharmaceutical product
                                    or is otherwise convicted of or charged with
                                    violation of any law that could subject it,
                                    or them, to criminal penalty.

         (b)      Subject to the conditions and limitations set forth in Section
                  14 hereof, Mallinckrodt hereby agrees to indemnify, defend and
                  hold harmless King from and against any and all Damages
                  asserted against, resulting to, imposed upon or incurred by
                  King, directly or indirectly related to, arising out of or
                  resulting from:

                  (i)      any breach or failure of any of the representations
                           and warranties of Mallinckrodt contained herein,

                  (ii)     any breach or any failure of Mallinckrodt to perform
                           any obligation herein,

                  (iii)    any Damages caused by the failure of Key Materials
                           supplied by Mallinckrodt to meet applicable
                           specifications, or otherwise caused by the Key
                           Materials, and

                  (iv)     any Damages, to the extent and only to the extent
                           related to the Key Materials, arising as a
                           consequence of the following:

                           (A)      a recall, withdrawal, or suspension of any
                                    product registration, product license,

                                    consent with respect to the production Key
                                    Materials by Mallinckrodt, or

                           (B)      any injunction or other order issued by any
                                    court of appropriate jurisdiction which
                                    requires Mallinckrodt to suspend its
                                    operations relative to the production of Key
                                    Materials pending further approval or
                                    authorization from a governmental official
                                    or agency or which otherwise has a material
                                    adverse effect on Mallinckrodt's performance
                                    hereunder.

         (c)      In the event that the Indemnified Party shall reasonably
                  believe that it has a claim for Damages ("Damage Claim"), it
                  shall give prompt notice in accordance herewith to the
                  Indemnifying Party of the nature and extent of such Damage
                  Claim and the Damages incurred by it. If the Damages are
                  liquidated in amount, the notice shall so state, and such
                  amount shall be deemed the amount of such Damage Claim of the
                  Indemnified Party against the Indemnifying Party (subject to
                  the right of the Indemnified Party to submit claims for
                  additional Damages incurred after the date of any such
                  notice). If the amount is not liquidated, the notice shall so
                  state and, in such event, such Damage Claim shall be deemed
                  asserted against the Indemnifying Party, but no payment or
                  satisfaction shall be made on account thereof until the amount
                  of such claim is liquidated.

         (d)      If the Indemnifying Party shall not, within thirty (30) days
                  after the giving of such notice by the Indemnified Party,
                  notify the Indemnified Party in accordance herewith that the
                  Indemnifying Party disputes the right of the Indemnified Party
                  to indemnity in respect of such Damage Claim, then any such
                  Damage Claim shall be paid or satisfied as follows: (i) if
                  said Damage Claim is liquidated, the full amount of Damages
                  associated with such Damage Claim shall be paid to the
                  Indemnified Party by the Indemnifying Party at the end of such
                  thirty (30) day period, or (ii) if the amount of such Damage
                  Claim is unliquidated at the time notice is

                                       40


<PAGE>   41
                  originally given to the Indemnifying Party, the Indemnified
                  Party shall give a second notice to the Party when the
                  liquidated amount of such Damage Claim is known and, unless
                  the Indemnifying Party shall object in writing to such amount
                  (as opposed to the Damage Claim itself, as to which the right
                  to dispute had expired) within twenty (20) days after the
                  giving of said second notice, then payment of the Damages
                  associated with such Damage Claim shall be made by the
                  Indemnifying Party to the Indemnified Party at the end of such
                  twenty (20) day period.

         (e)      Any portion of the amount of Damages asserted by an
                  Indemnified Party in connection with a Damage Claim shall, if
                  not objected to by the Indemnifying Party in accordance with
                  the procedures established herein, be considered to be subject
                  to satisfaction by payment without further objection.

         (f)      If an Indemnifying Party shall notify the Indemnified Party
                  that it disputes any Damage Claim or the amount thereof (which
                  notice shall only be given if the Indemnifying Party has a
                  good faith belief that the Indemnified Party is not entitled
                  to indemnity or the full amount of indemnity as claimed) then
                  the parties hereto shall endeavor to settle and compromise
                  such claim, or may agree to submit the same to arbitration,
                  and, if unable to agree on any settlement or compromise or on
                  submission to arbitration, such claim shall be settled by
                  appropriate litigation, and any liability and the amount of
                  the Damages established by reason of such settlement,
                  compromise, arbitration or litigation, or incurred as a result
                  thereof, shall be paid and satisfied as provided herein.

         (g)      An Indemnified Party will promptly give notice to the
                  Indemnifying Party of any claim of a third party which may
                  reasonably be expected to result in a Damage Claim by the
                  Indemnified Party. An Indemnifying Party shall have the right
                  to direct the defense, compromise or settlement of such claim
                  with counsel selected by it, provided the Indemnifying Party
                  gives written notice to the Indemnified Party of its election
                  to do so within twenty (20) days after receipt of notice in
                  accordance with the preceding


                                       41




<PAGE>   42



                  sentence. If the Indemnifying Party fails to so notify the
                  Indemnified Party of its election to defend any such third
                  party claim the Indemnified Party will (upon further notice
                  to the Indemnifying Party) have the right to undertake the
                  defense, compromise or settlement of such claim on behalf of
                  and for the account and expense of the Indemnifying Party,
                  subject to the right of the Indemnifying Party to assume the
                  defense of such claim at any time prior to settlement,
                  compromise or final determination thereof if and only if such
                  assumption would not prejudice the defense of such claim or
                  the rights of the Indemnified Party.

         (h)      In the event an Indemnifying Party has assumed the defense of
                  any such claim, the Indemnified Party shall nonetheless have
                  the right to select its own counsel and participate in the
                  defense of such claim at and for its own expense and account,
                  subject to the right of the Indemnifying Party to retain
                  ultimate control of the management of the defense of such
                  claim, and further subject to the obligation of the
                  Indemnified Party reasonably to cooperate in all respects with
                  the Indemnifying Party for the effective defense of such
                  claim. Counsel for the Indemnified Party in such circumstances
                  shall consult and cooperate with counsel for the Indemnifying
                  Party in defending against any such third party claim.

         (i)      An Indemnifying Party shall not under any circumstances,
                  without the written consent of the Indemnified Party, settle
                  or compromise any claim or consent to the entry of any
                  judgment which does not include as an unconditional term
                  thereof the giving by the claimant or the plaintiff to the
                  Indemnified Party a release from all liability in respect of
                  such claim, in form and substance reasonably satisfactory to
                  the Indemnified Party.

         (j)      Notwithstanding anything to the contrary contained herein, if
                  a third party claim is made which the third party is
                  unequivocally willing to settle for the payment of money but
                  the Indemnified Party elects not to settle, then the
                  Indemnifying Party shall not be liable hereunder with respect
                  to any Damage Claim arising from such third party claim for
                  more than the amount which such third party at any time

                  the preceding sentence, "cause" shall mean (without

                  any bankruptcy or insolvency law against a party, unless such
                  petition is dismissed or set aside within sixty (60) days from
                  the date of its filing, or (v) the appointment of a receiver
                  or trustee for the assets or business of a party, unless such
                  appointment is dismissed or set aside within sixty (60) days
                  from the date of such appointment.

         (c)      Notwithstanding subsection (b) set forth immediately above,
                  Mallinckrodt shall additionally have the right to terminate
                  this Manufacturing Agreement effective immediately upon
                  written notice to King in the event that (i) King suffers a
                  suspension of any product registration, product license,
                  manufacturing license (e.g., an NDA or ANDA), or other

                  governmental license, approval or consent with respect to any
                  of its dosage pharmaceutical products, (ii) to the extent it
                  may adversely effect King's performance hereunder, King
                  suffers any injunction or other order issued by any court of
                  appropriate jurisdiction which requires it to recall products
                  or suspend its operations with respect to some or all of its
                  dosage pharmaceutical products pending further approval or
                  authorization from a governmental official or agency or which
                  otherwise has a material adverse effect on its dosage
                  pharmaceutical operations of any sort, or (iii) King, or any
                  of its employees or affiliates, is debarred under relevant

                  convicted of or formally charged with a criminal offense
                  relating to the development or approval process or the
                  manufacture or sale of any drug or pharmaceutical product or
                  is otherwise convicted of or charged with violation of any law
                  that could subject it, or them, to criminal penalty, (iv)
                  King is otherwise, on a consistent basis, not in material
                  compliance with any laws, rules, and regulations relative to
                  production hereunder or the performance of its obligations
                  hereunder, (v) King is unable or unwilling to produce
                  finished product conforming to all applicable specifications
                  and the requirements hereof as and when reasonably requested
                  by Mallinckrodt, (vi) an event of force majeure (as described
                  in Section 15 hereof) prevents full performance by King
                  hereunder on a consecutive basis for a period of one hundred
                  twenty (120) days, or (vii) King has repeatedly and
                  materially breached its obligations hereunder.

         (d)      The representations and warranties of the parties hereunder,
                  covenants which by their terms have effect after the
                  termination or expiration hereof, and the parties'
                  indemnification and confidentiality obligations shall survive
                  termination or expiration of this Manufacturing Agreement.

20.      Assistance by King.

25.      Governing Law and Jurisdiction

         This Agreement shall be governed by and construed in accordance with
         the substantive and procedural laws (as opposed to the conflicts of law
         provisions of the State of Tennessee. In the event King initiates an
         action against Mallinckrodt, such action shall be brought in either
         the United States District Court for the Eastern District of Missouri
         or in the state courts of Missouri and King hereby consents to personal
         jurisdiction in said courts. King waives any and all rights to object
         on any basis (including inconvenience of forum) to the jurisdiction of
         such courts for the purpose of such litigation to enforce this
         Agreement or any rights of Mallinckrodt with respect to the subject
         matter hereof. In the event Mallinckrodt initiates an action against
         King, such action shall be brought in the United States District Court
         of the Eastern District of Tennessee in Greenville, Tennessee or in any
         state court sitting in Sullivan County, Tennessee or in Washington
         County, Tennessee and Mallinckrodt hereby consents to personal
         jurisdiction in said courts. Mallinckrodt waives any and all rights to
         object on any basis (including inconvenience of forum) to the
         jurisdiction of such courts for the purpose of such litigation to
         enforce this Agreement or any rights of King with respect to the
         subject matter hereof.

26.      Waiver.

         The failure by any party to exercise any of its rights hereunder or to
         enforce any of the terms or conditions of this Manufacturing Agreement
         on any occasion shall not constitute or be deemed a waiver of that
         party's rights thereafter to exercise any rights hereunder or to
         enforce each and every term and condition of this Manufacturing
         Agreement.

27.      Modifications.

         This Manufacturing Agreement may not be modified except by a writing
         specifically referring to this Manufacturing Agreement and executed by
         duly authorized representatives of both parties. The obligations of the
         parties are governed by the terms and conditions of this Manufacturing
         Agreement and none

                                       47




<PAGE>   48



         of the general terms and conditions of any Mallinckrodt purchase order
         or any King acknowledgement or any substantially similar documents of
         either party will in any case be controlling or supersede the
         provisions hereof.

28.      Precedence.

         In the event of any conflict or inconsistency between the terms of
         this Manufacturing Agreement and the Asset Purchase Agreement, the
         latter shall prevail.

29.      Severability.

         A determination that any portion of this Manufacturing Agreement is
         unenforceable or invalid shall not affect the enforceability or
         validity of any of the remaining portions hereof or of this
         Manufacturing Agreement as a whole. In the event that any part of any
         of the covenants, sections or provisions herein may be determined by a
         court of law or equity to be overly broad or against applicable
         precedent or public policy, thereby making such covenants, sections or
         provisions invalid or unenforceable, the parties shall attempt to reach
         agreement with respect to a valid and enforceable substitute for the
         deleted provisions, which shall be as close in its intent and effect as
         possible to the deleted portions.

30.      Headings.

         The parties agree that the section and article headings are inserted
         only for ease of reference, shall not be construed as part of this
         Manufacturing Agreement, and shall have no effect upon the construction
         or interpretation of any part hereof.

31.      Counterparts.

         This Manufacturing Agreement may be executed in several counterparts,
         and each executed counterpart shall be considered an original of this
         Manufacturing Agreement.

by certain negative covenants, including a covenant that King shall not encumber
particular assets used in connection with King's performance under the
Manufacturing Agreement; and

         WHEREAS, Mallinckrodt and King now desire that King be released from
certain negative covenants and restrictions contained in the Manufacturing
Agreement as herein specified, in consideration of Mallinckrodt being granted an

being equal to the Minimum Manufacturing Fee for the Fifth contract year of the

2.       Section 11 (e) of the Manufacturing Agreement shall he amended to read
in its entirety as follows:

         Unless Mallinckrodt gives King its written consent (which consent
         shall not, without business reason to Mallinckrodt, be withheld) King
         will not engage in any transaction whereby it (i) merges with any
         other person, firm or entity, or (ii) sells all, substantially all or a
         substantial portion of its assets to any person, firm or entity.

3.       The first sentence of Section 101(g) of the Manufacturing Agreement
shall be amended to read in its entirety as follows:


                                       2

<PAGE>   53



         King shall maintain a debt to city of no greater than three and one 
         half to one(3.5/1).

4.       The first sentence of Section 11 (h) of the Manufacturing Agreement
shall be deleted in its entirety from Section 11 (h), and for the avoidance of
doubt, the sentence to be deleted follows:

         King will not create, assume or suffer to exist on any of its assets
         used in any manner in connection with King's performance hereunder any
         mortgage, lien, pledge, security interest or encumbrance of any kind,
         except for (i) liens for current taxes not yet due, (ii) those existing
         liens set forth on Exhibit G attached hereto, and (iii) leases for
         equipment to be usual in connection with the King Business for
         manufacturing, development analytical and general office management
         purposes.

5.       Section 19(a) of the Manufacturing Agreement shall be amended by
adding the following at the end of the current text of said subsection:

         Notwithstanding the foregoing, Mallinckrodt shall have the options and
         right to terminate this Manufacturing Agreement on and as of December
         31, 1999, at the end of the fourth year of the initial term at no
         additional cost to Mallinckrodt, by providing written notice to King
         prior to or on June 30, 1999, of Mallinckrodt's exercise of such option
         to terminate the Manufacturing Agreement on and as of December 31,
         1999. In the event that Mallinckrodt elects not to exercise such option
         of early termination of this Manufacturing Agreement as set forth in

                                    GUARANTY

         Given this 14th day of February, 1997, by JOHN M. GREGORY, the
undersigned ("Guarantor"), to induce Mallinckrodt Chemical, Inc.
("Mallinckrodt"), to enter into the Amendment to the Toll Manufacturing
Agreement for APA,/Hydrocodone Bitartrate Tablets (the "Amendment") of even
date herewith, between Mallinckrodt and King Pharmaceuticals, Inc.
("King").

         1. Obligation. The undersigned hereby guarantees to Mallinckrodt
payment by King of any liabilities, costs and expenses, up to a total maximum
liability, including costs and expenses, of Two Million Dollars ($2,000,000.00),
arising from any default by King in the performance of King's representations,
warranties and obligations to Mallinckrodt under the terms of the Toll
Manufacturing Agreement (the "Manufacturing Agreement") dated December 13, 1995,
between Mallinckrodt and King, but only on the condition that, in the event King
defaults in the performance of King's representations, warranties and
obligations under the Manufacturing Agreement, Mallinckrodt shall take
appropriate steps (but not beyond the issuance or return of an execution on
judgment) pursuant to the Manufacturing Agreement to recover from King so much
of the liability, costs and expenses arising from such default as can thereby
reasonably be obtained, before requiring payment of any part thereof from the
undersigned.

         2. Term. This instrument shall constitute a continuing guaranty
covering the payment of all liabilities, costs and expenses arising from any
default by King in the performance of King's representations, warranties and
obligations under the Manufacturing Agreement, up to a maximum liability of Two
Million Dollars ($2,000,000.00), and shall be binding upon the undersigned until
King's fulfillment of all of its obligations under the Manufacturing
Agreement and termination or expiration of the Manufacturing Agreement in
accordance with the terms therein.

         3. Applicable Law.  This Guaranty has been delivered to Mallinckrodt in
the State of Tennessee and shall be construed and enforced in accordance with
the laws thereof without regard to its rules with respect to choice of law. No
provisions of this Guaranty may be

writing executed by the parties.

         IN WITNESS WHEREOF the Guarantor has duly signed this Guaranty on the
date stated above with the firm intention to be bound by the terms thereof and
with the understanding that Mallinckrodt, as the beneficiary of this Guaranty,
is relying thereon.

         issued from time to time by a Letter of Credit Issuer, in an aggregate
         principal amount at any time outstanding not to exceed the lesser of
         (A) such Lender's Revolving Credit Commitment and (B) such Lender's
         Proportionate Share of the Borrowing Base, and provided that the
         outstanding amount of Letter of Credit Obligations arising under

                  (ii) from the Agreement Date to but excluding the Term Loan

<PAGE>   9



Credit Issuer, each Letter of Credit Issuer agrees to issue, and to sell
participations in, its Letters of Credit as provided in Section 2.1.

                  (c) Proportional Participation. Each Lender shall make a Loan
with respect to each Borrowing and shall purchase a participation in each Letter
of Credit in the amount of its Proportionate Share of such Borrowing or Letter
of Credit.

         Section 1.2 Borrowing Options; Method of Borrowing.

                  (a) Borrowing Options. Loans of any Class, at the option of
the Borrower, may be made as one or more Base Rate Borrowings or Eurodollar
Borrowings, or any combination thereof. Each Base Rate Borrowing shall be in a
minimum amount of $100,000. Each Eurodollar Borrowing shall be in a minimum
amount of $1,000,000 and in greater whole multiples of $100,000. There shall at
no time be in effect more than five Eurodollar Borrowings.

                  (b) Method of Borrowing. Whenever the Borrower desires to
incur a Borrowing it shall give the Agent notice of such requested Borrowing(s)
in the form of Schedule 1.2(b) (a "Notice of Borrowing") (which shall be
irrevocable), in the case of the incurrence of a Base Rate Borrowing one
Business Day, and in the case of the incurrence of a Eurodollar Borrowing, three
Business Days, before the requested date of such Borrowing, specifying: (i) the
requested date of the Borrowing(s), which shall be a Business Day, (ii) the
aggregate principal amount of the Borrowing(s) to be incurred, (iii) the Class
and Type of the Loans comprising such requested Borrowing(s), and (iv) in the
case of the incurrence of a Eurodollar Borrowing, the duration of the Interest
Period, subject to the provisions of the definition of Interest Period. In the
absence of an acceleration of the Obligations pursuant to Section 7.2, if a
request for a Eurodollar Borrowing is not made, or is not made in accordance
with this Section, upon the maturity of a Eurodollar Borrowing, and the Agent
shall not have received notice from the Borrower of its intention to repay such
Loans other than with the proceeds of a Rollover Borrowing at least one Business
Day prior to such maturity, then the Borrower shall be deemed to have requested
a Base Rate Borrowing in an amount necessary to repay such maturing Borrowing.
Any Notice of Borrowing received after noon (New York City time) shall be deemed
received on the following Business Day.

                  (c) Funding Of Loans. (i) After receiving a Notice of
Borrowing, the Agent shall notify each Lender of the contents of such Notice of
Borrowing, of such Lender's Proportionate Share of the requested Borrowing and,
in the case of a Eurodollar Borrowing, the applicable interest rate. Except as
provided in subsection (f) below and subject, in the case of Eurodollar
Borrowings, to the provisions of Article VIII, each Lender shall make available
to the Agent at the Agent's Office its Proportionate Share of any requested
Borrowing, in lawful money of the United States of America in immediately
available funds, prior to 12:00 Noon (New York City time) on the Business Day
requested for such Borrowing. The Agent shall, subject to the satisfaction of
the conditions set forth in Article III, by 3:00 p.m. (New York City time) on
such day, credit the amounts received by it in like funds to the Disbursement
Account or in such other manner as the Borrower and the Agent shall agree.



<PAGE>   10



                  (d) Rollover Borrowings. If any Lender makes a new Loan
hereunder on a day on which the Borrower is to repay all or any part of an
outstanding Loan from such Lender, such Lender shall apply the proceeds of its
new Loan to make such repayment (the amount of such new Loan made to repay a
maturing loan, a "Rollover Borrowing") and only an amount equal to the
difference (if any) between the amount being borrowed and the amount being
repaid shall be made available by such Lender as provided in subsection (e) of
this Section or remitted by the Borrower to the Agent as provided in Section
1.6.

                  (e) Agent May Assume Funding. Unless the Agent shall have
received notice from a Lender prior to the date of any Borrowing that such
Lender will not make available to the Agent such Lender's Proportionate Share of
such Borrowing, the Agent may assume that such Lender has made such amount
available to it on the date of such Borrowing in accordance with subsection (c)
of this Section 1.2, and may, in reliance upon such assumption, make available
for the account of the Borrower on such date a corresponding amount. If and to
the extent that such Lender shall not have so made such Proportionate Share
available to the Agent such Lender shall pay to the Agent forthwith on demand,
such corresponding amount together with interest thereon, for each day from the
date such amount is made available to the Borrower until the date such amount is
paid to the Agent at the Federal Funds Rate. If such Lender shall pay to the
Agent, such corresponding amount, such amount so paid shall constitute such
Lender's Loan as part of such Borrowing for purposes of this Agreement. If such
Lender shall fail to pay such corresponding amount upon such demand, then the
Borrower shall, forthwith on demand, repay to the Agent, such corresponding
amount, together with interest thereon for each day from the date such amount is
made available to the Borrower until the date such amount is paid, at the
interest rate applicable at such time to Loans comprising such Borrowing.

                  (f) Lenders' Obligations Independent. The failure of any
Lender to make a Loan to be made by it as part of any Borrowing or to purchase
any participation hereunder shall not relieve any other Lender of its
obligation, if any, hereunder to make its Loan on the date of such Borrowing or
to purchase any such participation. Neither the Agent nor any Lender shall be
responsible for the failure of any other person to make any Loan or to purchase
any participation hereunder on the date required therefor.

         Section 1.3. Evidence of Indebtedness.

                  (a) Notes. The Loans by each Lender to the Borrower and the
Borrower's obligations to repay such Loans with interest in accordance with the
terms of this Agreement, shall be evidenced by (i) in the case of Base Rate
Revolving Loans, a single Base Rate Revolving Note and (ii) in the case of
Eurodollar Revolving Loans, a single Eurodollar Revolving Note.

                  (b) Authorization to Make Notations. Each Lender shall record,
and prior to any transfer of any Note shall endorse on the schedules forming a
part thereof appropriate notations to evidence the date, amount and maturity of
each Loan made by it and the date and amount of each payment of principal made
by the Borrower with respect thereto; provided that the failure of any Lender



<PAGE>   11



to make any such recordation or endorsement shall not affect the obligations of
the Borrower hereunder or under the Notes. Each Lender is hereby irrevocably
authorized by the Borrower to so endorse its Note or Notes and to attach to and
make a part of its Note or Notes a continuation of any such schedule as and when
required.

                  (c) Loan Account and Accounting. Agent shall maintain a loan
account (the "Loan Account") on its books to record: (a) all Loans and Letter of
Credit Obligations, (b) all payments made by Borrower, and (c) all other debits
and credits as provided in this Agreement with respect to the Loans or any other
Obligations. All entries in the Loan Account shall be made in accordance with
Agent's customary accounting practices as in effect from time to time. The
balance in the Loan Account, as recorded on Agent's most recent printout or
other written statement, shall be presumptive evidence of the amounts due and
owing to Agent and Lenders by Borrower; provided that any failure to so record
or any error in so recording shall not limit or otherwise affect Borrower's duty
to pay the Obligations. Agent shall render to Borrower a monthly accounting of
transactions with respect to the Loans and Letter of Credit Obligations setting
forth the balance of the Loan Account. Unless Borrower notifies Agent in writing
of any objection to any such accounting (specifically describing the basis for
such objection), within thirty (30) days after the Borrower's receipt thereof,
each and every such accounting shall (absent manifest error) be deemed final,
binding and conclusive upon Borrower in all respects as to all matters reflected
therein. Only those items expressly objected to in such notice shall be deemed
to be disputed by Borrower.

         Section 1.4  Interest.

                  (a) Rates. Each Loan shall bear interest on the outstanding
principal amount thereof at a rate per annum equal to, (i) so long as it is a
Base Rate Loan, the Base Rate as in effect from time to time plus the Applicable
Margin, (ii) so long as it is a Eurodollar Loan, the applicable Adjusted
Eurodollar Rate plus the Applicable Margin, and (iii) from and including the
date of the occurrence of any Default to but excluding the date that such
Default shall have been cured or waived in accordance herewith, the Default Rate
and all other Obligations bearing interest under this agreement shall also bear
interest at the Default Rate during such period.

                  (b) Default Rate Interest. If all or any part of a Loan or
other Obligation is not paid when due (whether at maturity, by reason of notice
of prepayment or acceleration or otherwise), such unpaid amount shall bear
interest for each day during the period from the date such amount became so due
until it shall be paid in full (whether before or after judgment) at a rate per
annum equal to the Default Rate.

                  (c) Payments. Interest due pursuant to this Agreement shall be
payable in arrears, (i) in the case of Base Rate Loans, on each Interest Payment
Date, (ii) in the case of any Eurodollar Loan, on the last day of each Interest
Period applicable thereto, and (iii) in the case of any Loan or other
Obligation, when any portion of such Loan, or other Obligation shall be due
(whether at maturity, by reason of prepayment or acceleration or otherwise), but
only to the extent then accrued on the amount then so due. Interest at the
Default Rate shall be payable on demand.

         Section 1.5 Commitment and Other Fees.

                  (a)   Other Fees. The Borrower agrees to pay to the Agent such
fees as provided in the Fee Letter.

                  (b)   Revolving Credit Commitment Fee. The Borrower agrees to
pay to the Agent for the account of each Lender, for each day from and including
the Agreement Date to but excluding the Revolving Credit Commitment Termination
Date, an amount equal to .375% per annum on the daily unused Revolving Credit
Commitment of such Lender (the "Revolving Credit Commitment Fee"). Absent the
occurrence and continuation of a Default, at any time following the first
anniversary of the Closing Date, this fee will reduce to 0.25% per annum from
and after the fifth Business Day following the Agent's receipt of notice from
the Borrower that the Leverage Ratio as determined from the financial statements
most recently delivered pursuant to Section 6.1(b) or (c) was less than 2.25:1,
and shall continue so reduced until the earlier of a Default and the delivery of
financial statements pursuant to Section 6.1(b) or (c) from which it can be
determined that the Leverage Ratio is greater than or equal to 2.25:1.

                  (c)   Fees Payable in Arrears. All fees due pursuant to
Section 1.5(b), and the fees due pursuant to Section 2.4(a), shall be payable
monthly in arrears on the first Business Day in each Month , commencing with
January 2, 1997, on the applicable Termination Date and, in the case of the
Revolving Credit Commitment Fee, upon each reduction of such Commitment to the
extent accrued on the amount of such reduction.

         Section 1.6. Repayment of Loans.

                  (a)   Mandatory Payment. (i) All Revolving Loans outstanding
         on the Revolving Credit Commitment Termination Date shall mature and
         become immediately due and payable. On any date that the aggregate
         outstanding principal amount of Revolving Loans and Letter of Credit
         Obligations shall exceed the lesser of (x) the Borrowing Base and (y)
         the Revolving Credit Commitments, the Borrower shall repay Revolving
         Loans, and/or Letter of Credit Obligations in an amount equal to such
         excess.

                  (ii)  All Term Loans outstanding on the Term Loan Credit
         Commitment Termination Date shall mature and become immediately due and
         payable. On any date that the aggregate outstanding principal amount of
         Term Loans shall exceed the Term Loan Credit Commitments, the Borrower
         shall repay Term Loans in an amount equal to such excess.

                  (iii) All Eurodollar Loans shall mature and become due and
         payable on the last day of the Interest Period applicable thereto.

                  (b)   Optional Payment. The Borrower may at any time upon one
Business Days' notice prepay Base Rate Loans in whole or in part without premium
or penalty, except that any prepayment of Base Rate Loans shall be in an
aggregate principal amount of at least $100,000 and in greater whole multiples
of $50,000, subject, however, to the Borrower's right to repay all outstanding
Loans in full, and except that Eurodollar Loans may not be optionally prepaid.
Amounts to be prepaid 


<PAGE>   13

shall irrevocably be due and payable on the date specified in the applicable
notice of prepayment, together with interest thereon as provided in Section
1.4(c).

                  (c)   Revolving Credit. Prior to the Revolving Credit
Commitment Termination Date and subject to the terms and conditions hereof,
Revolving Loans may be repaid and reborrowed. Except in the case of Rollover
Borrowings, Term Loans may not be repaid and reborrowed.

         Section 1.7. Reductions of Commitments.

                  (a)   Optional Reductions of Commitments. Subject to the
following sentence, the Borrower may elect to reduce any Commitment, in whole or
in part, by (i) giving the Agent not less than 30 Business Days' prior written
notice thereof, (ii) in the case of the Revolving Credit Commitment and the Term
Loan Commitment, paying to the Agent for the ratable account of the Lenders the
amount by which the sum of all outstanding Loans thereunder exceeds such
Commitment as so reduced, together with any accrued and unpaid interest and fees
thereon. Partial reductions of Commitments of any Class pursuant to this Section
1.7 shall be in incremental amounts of $1,000,000.

                  (b)   Mandatory Reduction of Commitments. (i) The Revolving
Credit Commitments shall reduce automatically to zero on the Revolving Credit
Commitment Termination Date.

                  (ii)  The Term Loan Commitments shall reduce automatically (A)
         to the amount of the Term Loans outstanding at the close of the Agent's
         business on the Closing Date, (B) by $1,428,571.43 on the last day of
         each Fiscal Quarter, commencing February 27, 1997, (C) by the amount of
         any prepayment not made with the proceeds of a Rollover Borrowing, and
         (D) to zero on the earlier of the Term Loan Commitment Termination Date
         and the Revolving Credit Commitment Termination Date.

                  (iii) The Term Loan Commitments shall reduce by the amount by
         which the Net Proceeds received by the Borrower or any Subsidiary
         during any fiscal year from all asset dispositions (including
         condemnation proceeds, but excluding proceeds of asset dispositions
         permitted by clauses (x) and (y) to the proviso to Section 5.7) and
         from all sales of Stock of Subsidiaries, exceeds $100,000 (such excess
         amount, the "Excess Net Proceeds"). Such reduction shall occur on the
         date that financial statements are delivered by the Borrower pursuant
         to Section 6.1(c) and on each earlier date that the cumulative amount
         of such Excess Net Proceeds not yet applied to reduce the Term Loan
         Commitment shall exceed $100,000.

                  (iv)  If Borrower issues any Capital Securities or any debt
         securities, other than in connection with the IPO, no later than the
         Business Day following the date of receipt of the proceeds thereof, the
         Term Loan Commitments shall reduce in an amount equal to 50% of the Net
         Proceeds of such issuance.

                  (v)   Commencing with the delivery of the financial statements
         for fiscal year 1998 and continuing until the Termination Date for each
         year that the Leverage Ratio for such year as shown on such financial
         statement, is greater than 2.5:1, the Term Loan Commitments shall
         reduce on the earlier of the date which is ten (10) days after (A) the
         date on which Borrower's 


<PAGE>   14



         annual audited Financial Statements for such Fiscal Year are delivered
         pursuant to Section 6.1(c) and (B) the date on which such annual
         audited Financial Statements were required to be delivered pursuant to
         Section 6.1(c), in an amount equal to 75% of Excess Cash Flow for such
         Fiscal Year. Each such prepayment shall be accompanied by a certificate
         signed by the Borrower's chief financial officer certifying the manner
         in which Excess Cash Flow and the resulting prepayment were calculated,
         which certificate shall be in form and substance reasonably
         satisfactory to Agent.

                  (c) Application of Commitment Reductions. Commitment
reductions pursuant to Sections 1.7(a), and 1.7(b)(iii) through (v) shall be
applied against commitment reductions required pursuant Section 1.7(b)(ii) in
the inverse order of the occurrence thereof.

                  (d) Ratable Reduction of Commitments. Each reduction in
Commitments pursuant to this Section 1.7 shall permanently reduce the
appropriate Commitment of each Lender by an amount equal to its Proportionate
Share of such reduction.

         Section 1.8  Computation of Interest and Fees. Interest and fees due
pursuant to this Agreement that are calculated at a per annum rate, unless
expressly stated to the contrary with respect to a particular item of interest
or a particular fee, shall be computed on the basis of a year of 360 days, and
paid, in arrears, for the actual number of days elapsed (including the first but
excluding the last day, which, in the case of any Interest Period, means from
and including the first day of such Interest Period to but excluding the last
day thereof). If the date for any payment of principal is extended (whether by
operation of this Agreement, any provision of law or otherwise), fees payable
pursuant to this Agreement as well as interest, shall be payable for such
extended time.

         Section 1.9  Maximum Interest Rate. Nothing contained in this Agreement
or any Note shall require the Borrower to pay interest at a rate exceeding the
Maximum Permissible Rate. If amounts payable to the Agent, any Letter of Credit
Issuer or the Lenders on any date would be treated as interest in excess of the
Maximum Permissible Rate, such amounts automatically shall be reduced to the
Maximum Permissible Rate, and payments for any subsequent period, to the extent
less than the Maximum Permissible Rate, shall, to that extent, be increased by
the amount of such reduction.

         Section 1.10 Manner of Payment; Application of Payments. Unless
otherwise provided herein, all payments and deposits due from the Borrower to
the Lenders, the Agent or any Letter of Credit Issuer hereunder or under the
Notes, or under any Reimbursement Agreement, shall be made not later than 12:00
noon (New York time), on the due date thereof, in Dollars in funds immediately
available (i) in the case of Loans and other payments hereunder, other than
Reimbursement Obligations, to the Agent to the Agent's Account, for the account
of, (A) in the case of payments on account of Eurodollar Loans, the Lenders'
Eurodollar Lending Offices, (B) in the case of all other payments hereunder for
the account of the Lenders, the Lenders' Base Rate Lending Offices and (C) in
the case of all payments for the account of the Agent, the Agent's Office, and
(ii) in the case of any Reimbursement Obligation or any amounts due to any
Letter of Credit Issuer, at such Letter of Credit Issuer's Office, without any
deduction whatsoever, including, but not limited to, any deduction for any
set-off, recoupment, counterclaim or Tax.

         Section 1.11 Return of Payments. If the Agent or any Letter of Credit
Issuer shall be required by any court, trustee or debtor-in-possession or other
person to return any amount previously received by it in respect of the
Obligations under this Agreement or any Reimbursement Agreement, upon receipt
of notice from it, each Lender shall immediately pay over to it, such Lender's
Proportionate Share of the amount to be returned.

         Section 2.1 Letters of Credit.

                  (a)  Purchase of Participations by Lenders. Simultaneously
with the issuance by any Letter of Credit Issuer of any Letter of Credit each
Lender shall be deemed to have irrevocably and unconditionally purchased and
received without recourse or warranty, an undivided interest and participation
in such Letter of Credit (including, without limitation, all Obligations of the
Borrower with respect thereto except those expressly stated to be payable to the
Letter of Credit Issuer or the Agent hereunder or under the other Loan
Documents) and any documents or security therefor or Guaranty pertaining
thereto, equal to such Lender's Proportionate Share of such Letter of Credit.
The Agent shall promptly notify the Lenders upon the issuance of any Letter of

                  (c)  Terms of Letters of Credit.

                  (i)  Each Letter of Credit shall be in such form as the
         Borrower, the Agent and the Letter of Credit Issuer issuing such Letter
         of Credit shall agree. Each Letter of Credit shall expire on or prior
         to the Revolving Credit Commitment Termination Date. The aggregate
         stated amount of the Letters of Credit outstanding at any one time
         shall not exceed $3,000,000. The Letters of Credit shall be issued
         solely in connection with utility, bid, payment and/or performance
         bonds, or to secure the Borrower's obligations in respect of worker's
         compensation insurance.

                  (ii) In addition to any obligation of the Borrower hereunder
         with respect to the Letters of Credit and drawings thereunder, the
         Borrower's Reimbursement Obligations and any additional obligations in

Credit Issuer of any draft upon, or other notice of drawing under, a Letter of

shall pay to any Letter of Credit Issuer prior to 2:00 p.m. (New York City time)
on the date each Letter of Credit Issuer honors each drawing under such Letter
of Credit Issuer's Letter of Credit such Lender's Proportionate Share of such
Letter of Credit drawing; provided, that, if the Borrower should pay in full or
in part any Letter of Credit drawing on the date thereof, the obligation of each
Lender to pay to such Letter of Credit Issuer pursuant to this Section its
proportionate share of such drawing shall be reduced by an amount equal to such
Lender's Proportionate Share of such payment. Amounts paid in excess of the net
amount so owed shall promptly be refunded by such Letter of Credit Issuer to
such Lender.

                  (c) Failure to Pay by Lenders. If any Lender shall fail to pay
the amount of its participation in a Letter of Credit drawing on the date such
amount is due in accordance with subsection (b) above, the Letter of Credit
Issuer to which such payment is due shall be deemed to have advanced funds on
behalf of such Lender. Each such advance shall be secured by such Bank's
participation interest, and such Letter of Credit Issuer shall be subrogated to
such Lender's rights hereunder in respect thereof. Such advance may be repaid by
application to such advance of any payment that such Lender is otherwise
entitled to receive under this Agreement. Any amount not paid by such Lender to
such Letter of Credit Issuer hereunder shall bear interest for each day from the
day such payment was due until such payment shall be paid in full at a rate per
annum equal to the Federal Funds Rate.

                  (d) Repayment by Borrower. The Borrower shall repay to each
Letter of Credit Issuer for the ratable account of the Lenders the amount of
each Letter of Credit Obligation under any Letter of Credit issued by such
Letter of Credit Issuer on the date provided in the applicable Reimbursement
Agreement (which, in the case of a drawing under a Letter of Credit, shall be
the date of such drawing); provided, that, notwithstanding anything in this
Agreement or any Reimbursement Agreement to the contrary, all Letter of Credit
Obligations (fixed or contingent, drawn or undrawn) not previously due and
payable shall become due and payable by the Borrower on the Revolving Credit
Commitment Termination Date. The amount of any Letter of Credit Obligation that
is not paid when due shall bear interest, payable on demand, from the due date
thereof until paid, at the Default Rate. The Borrower agrees that it shall be
indebted to each Lender in an amount equal to such Lender's Proportionate Share
of each Letter of Credit Obligation, including each drawing paid by any Letter
of Credit Issuer under a Letter of Credit.

                  (e) Borrower's Obligations Absolute. The obligation of the
Borrower to pay a Letter of Credit Issuer for the account of the Lenders, for
each Letter of Credit Obligation arising under the Letter of Credit issued by
such Letter of Credit Issuer shall be irrevocable, shall not be subject to any


<PAGE>   18


qualification or exception whatsoever and shall be binding in accordance with
the terms and conditions of this Agreement under all circumstances, including,
without limitation, the following circumstances:

                  (i)   any lack of validity or enforceability of this Agreement
         or any of the other Loan Documents;

                  (ii)  the existence of any claim, set-off, defense or right
         which the Borrower may have at any time against a beneficiary of any
         Letter of Credit or any transferee of any Letter of Credit (or any
         person for whom any such transferee may be acting), the Agent, such
         Letter of Credit Issuer, the Lenders or any other Person, whether in
         connection with this Agreement, any Reimbursement Agreement or any
         Letter of Credit, the transactions contemplated herein or any unrelated
         transactions;

                  (iii) any draft, certificate or any other document presented
         under any Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient (except for insufficiencies that are manifest) in any
         respect or any statement therein being untrue or inaccurate in any
         respect;

                  (iv)  the surrender or impairment of any security for the
         performance or observance of any of the terms of this Agreement or the
         other Loan Documents;

                  (v)   any failure of the Agent or any Letter of Credit Issuer
         to provide notice to the Borrower of any drawing under any Letter of
         Credit;

                  (vi)  the occurrence or continuance of any Default; or

                  (vii) any other reason that is not finally determined by a
         court of competent jurisdiction to have been the result of gross
         negligence or willful misconduct on the part of such Letter of Credit
         Issuer.

         The foregoing provisions shall not in any way act as a waiver of any
claim, right, or cause of action which the borrower may have against a
beneficiary of any Letter of Credit or any transferee of any Letter of Credit
(or any person for whom any such transferee may be acting), whether arising in
connection with this Agreement, and Reimbursement Agreement of any Letter of
Credit, the transactions contemplated herein, or any unrelated transactions.

                  (f)   Lenders' Obligations Absolute. The obligation of each
Lender to pay to any Letter of Credit Issuer its Proportionate Share of each
drawing under a Letter of Credit issued by such Letter of Credit Issuer, (less
the amount thereof repaid by the Borrower as described above), shall be
irrevocable, unconditional, shall not be subject to any qualification or
exception whatsoever and shall be binding in accordance with the terms and
conditions of this Agreement under all circumstances, including, without
limitation, the following circumstances:

                  (i)   any lack of validity or enforceability of this 
Agreement;

         contemplated herein or any unrelated transactions;

                  (iii) any draft or any other document presented under this
         Agreement proving to be forged, fraudulent, invalid or insufficient
         (except for insufficiencies that are manifest) in any respect or any
         statement therein being untrue or inaccurate in any respect;

                  (iv)  the surrender or impairment of any security for the
         performance or observance of any of the terms of this Agreement;

                  (v)   the occurrence or continuance of any Default; or

                  (vi)  any other reason not constituting gross negligence or
         willful misconduct on the part of the Letter of Credit Issuer issuing
         such Letter of Credit.

         Section 2.4 Letter of Credit Fees; Administrative Fees; Interest.

                  (a)   Letter of Credit Fee. With respect to each Letter of

Credit Issuer, the fee agreed upon by the Borrower and such Letter of Credit
Issuer in the applicable Reimbursement Agreement.

                  (b)   Administrative Fees. In addition to the foregoing fees
payable to the Lenders, the Agent and the Letter of Credit Issuers, the Borrower

Reimbursement Agreement and such other administrative fees as such Letter of
Credit Issuer customarily charges in respect of letter of credit transactions
together with all telecommunication fees and other expenses incurred by such
Letter of Credit Issuer in connection with the issuance of, or any drawing

Obligations shall bear interest from and including the date of the creation
thereof until due at the Default Rate

         Section 2.5 Limitation of Liability With Respect To Letters of Credit.

Issuers, the Borrower assumes all risks of the acts and omissions of, or misuse

limiting the foregoing, the Agent, the Letter of Credit Issuers and the Lenders
shall not be responsible for:

                  (i)   the form, validity, sufficiency, accuracy, genuineness
         or legal effect of any draft, demand, application or other documents
         submitted by any party in connection with any Letter


<PAGE>   20

         (unless manifestly so);

                  (ii)   the validity, genuineness or sufficiency of any

                  (iii)  failure of the beneficiary of a Letter of Credit to
         comply fully with the conditions required in order to draw upon such
         Letter of Credit to the extent that the documents presented in
         connection with a drawing manifestly comply with the terms of such
         Letter of Credit;

                  (iv)   errors, omissions, interruptions or delays in
         transmission or delivery of any messages by mail, cable, telegraph,

                  (v)    errors in interpretations of technical terms;

                  (vi)   any loss or delay in the transmission or otherwise of
         any document required to make a drawing under any Letter of Credit or
         with respect to the proceeds thereof;

                  (vii)  the misapplication by the beneficiary of a Letter of
         Credit or of the proceeds of any drawing under such Letter of Credit;
         or

                  (viii) any consequences arising from causes beyond the control
         of Agent, the Letter of Credit Issuers or the Lenders, including,
         without limitation, any act or omission, rightfully or wrongfully, of
         any present or future governmental authority.

None of the above circumstances shall affect, impair or prevent the vesting of
any of the Agent's, the Letter of Credit Issuer's, or the Lenders' rights or
powers under this Agreement.

                  (b)    In furtherance and extension, and not in limitation, of
the specified provisions set forth above, any action taken or omitted by the
Agent or any Letter of Credit Issuer under or in connection with any Letter of
Credit or any Related Documents, if taken or omitted in good faith, shall not
expose the Agent, any Letter of Credit Issuer or any Lender to any liability to
the Borrower or relieve the Borrower from any of its obligations hereunder.

Section 2.2 shall constitute a representation and warranty by the Borrower, made
as of the time of the making of such Extension of Credit, that the conditions
specified in clauses (a) and (b) have been fulfilled as of such time, unless a
notice to the contrary specifically captioned "Disclosure Statement" is received
by the Agent from the Borrower prior to 2:00 p.m. (New York City time) on the
Business Day preceding the date of the requested Extension of Credit. To the
extent that the Required Lenders agree to make any Extension of Credit after

representations and warranties pursuant to the preceding sentence will be deemed
made as modified by the contents of such statement and repeated at the time of
the making of such Extension of Credit as so modified. Any such modification
shall be effective only for the occasion on which the Required Lenders elect to
make such Extension of Credit, and unless expressly agreed by the Required
Lenders in writing to the contrary as provided in Section 11.5, shall not be
deemed a waiver or modification of any condition to any other or future

                                       4.

               CERTAIN REPRESENTATIONS AND WARRANTIES OF BORROWER

         In order to induce the Lenders, the Agent and the Letter of Credit
Issuers to enter into this Agreement and to make each Extension of Credit, the
Borrower represents and warrants as follows:

         Section 4.1 Organization; Power; Qualification; Subsidiaries; Licenses;
Compliance with Laws; Title to Properties. (a) Each of the Borrower and its
Subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of its respective jurisdiction of incorporation, has the
corporate power and authority to own its respective properties and to carry on
its respective business as now being and proposed to be conducted hereafter and
is duly qualified and is in good standing, and is authorized to do business, in
all jurisdictions in which the character of its properties or the nature of its
businesses requires such qualification or authorization, except for
qualifications and authorizations the lack of which, singly or in the aggregate,
has not had and is not reasonably likely to have a Materially Adverse Effect
upon the Borrower and its Subsidiaries, taken as a whole. Schedule 4.1 (as may
be modified by written notice entitled "Disclosure Statement" delivered by the
Borrower to the Agent with the consent of the Agent from time to time) sets
forth a complete and correct list of all Subsidiaries of the Borrower, and their
respective jurisdictions of incorporation and the record ownership of their
shares, with all Consolidated Subsidiaries being identified as such. Schedule
4.1 also sets forth for the Borrower and each Subsidiary each jurisdiction which
such person is required to qualify to do business. The Borrower or another
Subsidiary of the Borrower owns 100% of the outstanding Capital Securities of
each Subsidiary of the Borrower listed as such on Schedule 4.1 and has the
unrestricted right to vote, and (subject to limitations imposed by Applicable
Law and Permitted Restrictive Covenants) to receive dividends and distributions
on, all of the issued and outstanding shares of the Capital Securities of each
such Subsidiary, and all such shares of Capital Securities have been duly
authorized and issued and are fully paid and nonassessable.

                  (b) Each of the Borrower and its Subsidiaries (i) has all
Governmental Approvals, to the extent required for such ownership, operation and
conduct, except, in each case, to the extent that the failure to have such
Governmental Approval, individually or in the aggregate, has not had and could
not reasonably be expected to have or result in a Materially Adverse Effect;
(ii) is in compliance with its charter and by-laws; and (iii) is in compliance
with all applicable provisions of law, except where the failure to comply,
individually or in the aggregate, has not had and could not reasonably be
expected to have or result in a Materially Adverse Effect.

         Section 4.2 Authorization and Compliance of Agreement, Notes and
Extensions of Credit. Each of the Borrower and the Guarantors has the corporate
power, and has taken all necessary corporate (including stockholder, if
necessary) action to authorize it, to execute, deliver and perform this
Agreement and each of the other Loan Documents to which it is a party in
accordance with the terms thereof, to borrow hereunder, to request the issuance
of Letters of Credit hereunder and to incur its other obligations under this
Agreement and each of the other Loan Documents to which it is a party. Each of
this Agreement and the other Loan Documents has been duly executed and delivered
by each



<PAGE>   27



of the Borrower and the Guarantors to the extent that it is party thereto, and
constitutes the legal, valid and binding obligation of such Person, enforceable
against such Person, in accordance with its terms. The execution, delivery and
performance of this Agreement and the other Loan Documents to which it is a
party by each of the Borrower and the Guarantors in accordance with their terms,
and the incurrence of Obligations thereunder, do not and will not (a) require
(i) any Governmental Approval, or (ii) any consent or approval of the
stockholders of the Borrower or any Guarantor that has not been obtained and is
not listed on, and a copy (certified in the case of Governmental Approvals) of
which is not attached to Schedule 4.2, (b) violate or conflict with, result in a
breach of, or constitute a default under, (i) any Contract to which the Borrower
or any Guarantor is a party or by which any of them or any of their properties
may be bound or (ii) any Applicable Law or (c) result in, or require the
creation of, any Lien upon any assets of the Borrower or any Guarantor other
than Liens created under this Agreement and the other Loan Documents in favor of
the Agent for the benefit of the Agent, the Lenders and the Letter of Credit
Issuers.

         Section 4.3 Litigation. Except as set forth on Schedule 4.3, there are
not, in any court or before any arbitrator of any kind or before or by any
governmental or non-governmental body, any actions, suits or proceedings,
pending or threatened (nor, to the knowledge of the Borrower, is there any basis
therefor) against or in any other way relating to or affecting () the Borrower
or any Subsidiary or the business or any property of the Borrower or any
Subsidiary, except actions, suits or proceedings that, if adversely determined,
would not, singly or in the aggregate, have a Materially Adverse Effect on the
Borrower and its Subsidiaries, taken as a whole, or () the Security Interest,
this Agreement or any other Loan Document.

         Section 4.4 Burdensome Provisions. Except as described on Schedule 4.4,
neither the Borrower nor any Subsidiary is a party to or bound by any Contract
or Applicable Law that could have a Materially Adverse Effect on (i) the
Borrower and its Subsidiaries, taken as a whole, or (ii) the Security Interest,
this Agreement or any of the other Loan Documents.

         Section 4.5 No Adverse Change or Event. Since September 30, 1997, no
change in the business, assets, liabilities, financial condition, results of
operations or business prospects of the Borrower or any Subsidiary has occurred,
and no event has occurred or failed to occur, that has had or reasonably could
be expected to have, either alone or in conjunction with all other such changes,
events and failures, a Materially Adverse Effect on (i) the Borrower and its
Subsidiaries, taken as a whole, or (ii) the Security Interest, this Agreement or
any other Loan Document. In determining whether an adverse change has occurred,
it is understood that such an adverse change may have occurred, and such an
event may have occurred or failed to occur, at any particular time
notwithstanding the fact that at such time no Default shall have occurred and be
continuing. If a fact or circumstance disclosed in the financial statements
referred to in Section 6.2(a) or a Disclosure Statement, or if an action, suit
or proceeding disclosed in Schedule 4.3, should in the future have, or appear
reasonably likely to have, a Materially Adverse Effect upon the Borrower and the
Subsidiaries, taken as a whole, or upon this Agreement, the Security Interest or
any other Loan Document, such Materially Adverse Effect shall be a change or
event subject to Section 4.5 notwithstanding such disclosure.



<PAGE>   28



         Section 4.6  No Adverse Fact. No fact or circumstance is known to the
Borrower, as of the Agreement Date, that, either alone or in conjunction with
all other such facts and circumstances, has had or reasonably could be expected
in the future to have a Materially Adverse Effect upon the Borrower and the
Subsidiaries, taken as a whole, or on the Security Interest, this Agreement or
any other Loan Document, that has not been set forth or referred to in the
financial statements referred to in Section 6.2(a) or in a writing specifically
captioned "Disclosure Statement" and delivered to the Agent prior to the
Agreement Date.

         Section 4.7  Title to Properties. Each of the Borrower and the
Subsidiaries has title to its respective properties reflected on the financial
statements referred to in Section 6.2(a) subject to no Liens or adverse claims
except as disclosed thereon and except for Permitted Liens.

         Section 4.8  Environmental Matters. () The Borrower and its
Subsidiaries (i) are and have been in compliance with all Environmental Laws;
(ii) have obtained, and are in compliance with, all Environmental Permits
required by Environmental Laws for the operations of their respective businesses
as presently conducted or as proposed to be conducted and all such Environmental
Permits are valid, uncontested and in good standing; (iii) are not involved in
operations that are likely to create, and know of no facts, circumstances or
conditions that are likely to result in, any Environmental Liabilities of such
Person, and have not permitted any current or former tenant or occupant of the
real estate to engage in any such operations; (iv) are aware of no litigation
arising under or related to any Environmental Laws, Environmental Permits or
Hazardous Material; (v) have not been notified that they may be a "potentially

Environmental Liabilities, in each case relating to any such Person; except for
any of the foregoing as individually or in the aggregate with all such events,

Materially Adverse Effect.

         Section 4.9  Debt All agreements relating to Debt of the Borrower or
any Subsidiary, or commitments or agreements to permit the Borrower or any
Subsidiary to incur Debt (other than any Loan Document) are described on
Schedule 4.9. The Borrower intends to use the proceeds of the credit provided
under this Agreement to repay and cancel all such Debt, except as described on
Part B on Schedule 4.9.

         Section 4.10 Patents, Trademarks, Etc. Each of the Borrower and its
Subsidiaries owns, or is licensed or otherwise has the lawful right to use, all
Patents used in or necessary for the conduct of its business as currently
conducted. The use of such Patents by the Borrower or the Subsidiary using or
requiring the same, does not infringe on the rights of any Person, subject to
such claims and infringements as do not, in the aggregate, give rise to any
liability that is material to the Borrower and its Subsidiaries, taken as a
whole.


<PAGE>   29


         Section 4.11 Solvency. (i) Each of the Borrower and its Subsidiaries
has received fair consideration and reasonably equivalent value for the
incurrence of its obligations hereunder and under the other Loan Documents to
which it is a party, (ii) after giving effect to the incurrence of such
obligations, (A) the present fair saleable value of each of the Borrower's and
its Subsidiaries' assets exceeds its liabilities, and (B) each retains
sufficient capital to meet the reasonably anticipated needs and risks of its
ongoing business, and (iii) after giving effect to the incurrence of such
obligations and the acquisition of such rights, (A) none has incurred, nor is it
obligated for, debts beyond its ability to pay such debts as they mature, and
(B) the present fair saleable value of its assets is greater than that needed to
pay its probable existing debts as they become due.

         Section 4.12 Security Interest. The Security Interest constitutes a
valid and perfected Lien of first priority, that is enforceable against each of
the Borrower and its Subsidiaries and all third parties subject only to
Permitted Liens.

         Section 4.13 The Questionnaire. Each Credit Party Questionnaire is
complete and correct in all respects.

         Section 4.14 Labor Matters. As of the Closing Date (a) no strikes or
other material labor disputes against the Borrower or any Subsidiary are pending
or, to the Borrower's knowledge, threatened; (b) hours worked by and payment
made to employees of the Borrower and its Subsidiaries comply with the Fair
Labor Standards Act and each other federal, state, local or foreign law
applicable to such matter, except for such non compliances as, singly or in the
aggregate, have not had and could not reasonably be expected to have or result
in a Material Adverse Effect; (c) all payments due from the Borrower or any
Subsidiary for employee health and welfare insurance have been paid or accrued
as a liability on the books of such Person, except for such non-payments or
non-accruals as, individually or in the aggregate, have not had and could not
reasonably be expected to have or result in a Material Adverse Effect; (d)
except as set forth in Schedule 4.14, neither the Borrower nor any Subsidiary is
a party to or bound by any collective bargaining agreement, management
agreement, consulting agreement or any material employment agreement (and true
and complete copies of any agreements described on Schedule 4.14 have been
delivered to Agent); (e) there is no organizing activity involving the Borrower
or any Subsidiary pending or, to Borrower's knowledge, threatened by any labor
union or group of employees; (f) there are no representation proceedings pending
or, threatened with the National Labor Relations Board, and no labor
organization or group of employees of any such Person has made a pending demand
for recognition; and (g) except as set forth in Schedule 4.14, there are no
complaints or charges against any the Borrower or any Subsidiary pending or, to
the knowledge of the Borrower, threatened to be filed with any Governmental
Authority or arbitrator based on, arising out of, in connection with, or
otherwise relating to the employment or termination of employment by any such
Person of any individual.

         Section 4.15 Governmental Regulation. Neither the Borrower nor any
Subsidiary is an "investment company" or an "affiliated person" of, or
"promoter" or "principal underwriter" for, an "investment company," as such
terms are defined in the Investment Company Act of 1940 as amended. Neither the
Borrower nor any Subsidiary is subject to regulation under the Public Utility
Holding Company Act of 1935, the Federal Power Act, or any other federal or
state statute that restricts or 


<PAGE>   30


limits its ability to incur Indebtedness or to perform its obligations
hereunder. The making of the Loans by the Lenders to Borrower, the incurrence of
the Letter of Credit Obligations on behalf of Borrower, the application of the
proceeds thereof and repayment thereof and the consummation of the Acquisition
will not violate any provision of any such statute or any rule, regulation or
order issued by the Securities and Exchange Commission.

         Section 4.16 Margin Regulations Neither the Borrower nor any Subsidiary
is engaged, nor will it engage, principally or as one of its important
activities, in the business of extending credit for the purpose of "purchasing"
or "carrying" any "margin security" as such terms are defined in Regulation U or
G of the Federal Reserve Board as now and from time to time hereafter in effect
(such securities being referred to herein as "Margin Stock"). Neither the
Borrower nor any Subsidiary owns any Margin Stock (except for investments
permitted pursuant to Section 6.2(a)(v)), and none of the proceeds of the Loans
or other Extensions of Credit will be used, directly or indirectly, for the
purpose of purchasing or carrying any Margin Stock, for the purpose of reducing
or retiring any Indebtedness which was originally incurred to purchase or carry
any Margin Stock or for any other purpose which might cause any of the Loans or
other extensions of credit under this Agreement to be considered a "purpose
credit" within the meaning of Regulation G, T, U or X of the Federal Reserve
Board. Neither the Borrower nor any Subsidiary will take or permit to be taken
any action which might cause any Loan Document to violate any regulation of the
Federal Reserve Board.

         Section 4.17 Taxes. All tax returns, reports and statements, including
information returns, required by any Governmental Authority to be filed by any
of the Borrower and its Subsidiaries have been filed with the appropriate
Governmental Authority and all charges have been paid prior to the date on which
any fine, penalty, interest or late charge may be added thereto for nonpayment
thereof (or any such fine, penalty, interest, late charge or loss has been
paid), excluding charges or other amounts being contested in accordance with
this Credit Agreement except for such filings or payments, the non-payment of
which, individually or in the aggregate, have not had and could not reasonably
be expected to have or result in a Materially Adverse Effect. Proper and
accurate amounts have been withheld by each of the Borrower and its Subsidiaries
from its respective employees for all periods in full and complete compliance
with all applicable federal, state, local and foreign law and such withholdings
have been timely paid to the respective Governmental Authorities except for such
withholdings and payments, the failure to make which, individually or in the
aggregate, have not had and could not reasonably be expected to have or result
in a Materially Adverse Effect. There are no pending or threatened assessments
currently outstanding. Neither the Borrower or any of its Subsidiaries nor, to
the Borrower's knowledge, their respective predecessors are liable for any
Taxes: (a) under any agreement (including any tax sharing agreements) or (b) as
a transferee.

         Section 4.18 ERISA. (a) As of the Closing Date, Schedule 4.18 lists and
separately identifies all Title IV Plans, Multiemployer Plans, ESOPs and Retiree
Welfare Plans. Copies of all such listed Plans, together with a copy of the
latest form 5500 for each such Plan, have been delivered to Agent. Each
Qualified Plan has been determined by the IRS to qualify under Section 401 of
the Code, and the trusts created thereunder have been determined to be exempt
from tax under the provisions of Section 501 of the Code, and nothing has
occurred which would cause the loss of such qualification or tax-exempt status.
Each Plan is in material compliance with the applicable provisions



<PAGE>   31



of ERISA and the Code, including the filing of reports required under the Code
or ERISA. Neither the Borrower nor any ERISA Affiliate has failed to make any
contribution or pay any amount due as required by either Section 412 of the Code
or Section 302 of ERISA or the terms of any such Plan. Neither the Borrower nor
any ERISA Affiliate has engaged in a prohibited transaction, as defined
inSection 4975 of the Code, in connection with any Plan, which would subject any
of the Borrower's or its Subsidiaries to a material tax on prohibited
transactions imposed by Section 4975 of the Code.

                  (b) Except as set forth on Schedule 4.18: (i) no Title IV Plan
has any Unfunded Pension Liability; (ii) no ERISA Event or event described in
Section 4062(e) of ERISA with respect to any Title IV Plan has occurred or is
reasonably expected to occur, which individually or in the aggregate, has had or
could reasonably be expected to have or result in a Materially Adverse Effect;
(iii) there are no pending, or to the knowledge of Borrower, threatened claims
(other than claims for benefits in the normal course), sanctions, actions or
lawsuits, asserted or instituted against any Plan or any Person as fiduciary or
sponsor of any Plan, which have a reasonable risk of being determined adversely
and which, if so determined, individually or in the aggregate, could have a
Materially Adverse Effect; (iv) neither the Borrower nor any ERISA Affiliate has
incurred or reasonably expects to incur any liability as a result of a complete
or partial withdrawal from a Multiemployer Plan; (v) within the last five years
no Title IV Plan with Unfunded Pension Liabilities has been transferred outside
of the "controlled group" (within the meaning of Section 4001(a)(14) of ERISA)
of the Borrower or any ERISA Affiliate; and (vi) no liability under any Title IV
Plan has been satisfied with the purchase of a contract from an insurance
company that is not rated AAA by the Standard & Poor's Corporation or the
equivalent by another nationally recognized rating agency.

         Section 4.19 Brokers. No broker or finder acting on behalf of the
Borrower or any Subsidiary brought about the obtaining, making or closing of the
Loans or the Related Transactions, and neither the Borrower nor any Subsidiary
has any obligation to any Person in respect of any finder's or brokerage fees in
connection therewith.

property (for the purposes of this clause, such Taxes shall be deemed to be due

become a Lien on any of its properties (other than any Tax or Liability to the
extent secured by a Permitted Lien or, in the case of any Tax not secured by a
Lien, to the extent such Tax is being contested in good faith by appropriate
proceedings and the Borrower has set aside adequate reserves on its books in
accordance with Generally Accepted Accounting Principles), (vi) pay its trade
payables in the ordinary course of its business consistent with past practice
and industry practice, subject however, to the Borrower's right to dispute items
in good faith, and (vii) at its cost and expense, take all such further actions
and obtain all consents and Governmental Approvals required or that the Agent
reasonably shall request so that the Obligations and the Security Interest will
at all times be valid, binding and enforceable in accordance with their
respective terms and entitled to the priority contemplated under the Loan
Documents and otherwise to effectuate the intent of the Loan Documents, except
that this Section 5.1 (other than clause (i), insofar as it requires the
Borrower and the Subsidiaries to preserve their corporate existence, clauses
(iii), (v) and (vi)) shall not apply in any circumstance where noncompliance,
together with all other noncompliances, will not have a Materially Adverse
Effect on (A) the Borrower and the Subsidiaries, taken as a whole, or (B) the
Security Interest, this Agreement or the other Loan Documents.

         Section 5.2 Insurance. (a) Maintain insurance with one or more
Acceptable Insurers against such risks and in such amounts as are specified on
Schedule 5.2, or as may be required by Applicable Law, or as reasonably may be

                  (b) All premiums on insurance policies required under this
Section shall be paid by the Borrower. All insurance policies shall contain loss

Such policies



<PAGE>   33



shall also name the Lenders, the Letter of Credit Issuers and the Agent as
additional insured parties, as their interest may appear, and shall provide
that:

                  (i)  all proceeds thereunder that relate to losses or damages
         sustained in respect of any item constituting a part of any Collateral
         (under any Mortgage or other Security Document) shall be payable to the
         Agent for the benefit of the Agent, the Letter of Credit Issuers and
         the Lenders, as their interest may appear, and

                  (ii) such insurance shall not be affected by any unintentional
         act or negligence on the part of the Borrower, any Subsidiary or other
         owner of the policy or the property described in such policy.

All such insurance policies shall provide that the insurer shall, simultaneously
with the delivery to the Borrower or such Subsidiary of any notice under such
policy, deliver a copy of such notice to the Agent. All such insurance policies
and loss payable clauses shall provide that they may not be canceled, amended or
terminated unless the Agent is given at least the same number of days' notice
that the insurance company that issued such policies is required to give the
Borrower or any Subsidiary, but in no event less than 30 days' prior written
notice. So long as no Default has occurred and is continuing, proceeds of such
insurance for all losses equal to or less than $100,000 per occurrence shall be
paid directly to the Borrower. Proceeds for all losses in excess of $100,000 per
occurrence shall be paid directly to the Agent for the benefit of the Agent, the
Letter of Credit Issuers and the Lenders, whereupon the Agent shall apply such
proceeds as provided in the Security Documents. Proceeds held by the Agent shall
be as security for the Obligations pending application thereto.

                  (c) The Borrower will not use the Inventory or Collateral, or
permit the Inventory or Collateral to be used, unlawfully or in any manner
inconsistent with the terms of any insurance coverage.

         Section 5.3 Use of Proceeds. Use (i) the proceeds of any Revolving Loan
for working capital purposes, to pay costs associated with this Agreement and
the other Loan Documents, and for general corporate purposes, (ii) the proceeds
of any Term Loan only to refinance the Debt listed on part A of Schedule 4.9, to
pay the purchase price and the costs associated with the Acquisition and (iii)
Letters of Credit shall be used only in connection with utilities, to secure
bid, performance or payment bonds, or to secure obligations in respect of
worker's compensation insurance. No Extension of Credit, and none of the
proceeds of any Extension of Credit shall be used to purchase or carry, or to
reduce or retire or refinance any credit incurred to purchase or carry, any
margin stock (within the meaning of Regulations G, T, U and X) or to extend
credit to others for the purpose of purchasing or carrying any margin stock. If
requested by the Agent, the Borrower will furnish to the Agent statements in
conformity with the requirements of Federal Reserve Form U-1 referred to in
Regulation U and



<PAGE>   34

the Extensions of Credit are at all times in compliance with Regulations G, T, U
and X.

                  (a) immediately notify the Agent and provide copies upon
receipt of all written claims, complaints or notices (excluding routine fee or
schedule notices) relating to compliance with, and liabilities or obligations
under, Environmental Laws or related common law theories with respect to its
facilities or properties and shall promptly cure and have dismissed with
prejudice to the satisfaction of the Required Lenders any actions or proceedings
relating to compliance with Environmental Laws; and

                  (b) provide such information and certifications that the Agent
may reasonably request from time to time to evidence compliance with this
Section 5.4.

         B. THE BORROWER SHALL NOT AND SHALL NOT PERMIT ANY SUBSIDIARY TO,
DIRECTLY OR INDIRECTLY:

         Section 5.5 Guaranties. Become or remain liable with respect to any
Guaranty except that this Section 5.5 shall not apply to (i) Existing Guaranties
or (ii) Permitted Guaranties.

         Section 5.6 Liens. Create, assume or incur, or permit or suffer to
exist or to be created, assumed or incurred, any Lien upon any of its properties
or assets of any character, whether now owned or hereafter acquired, or upon any
income or profits therefrom, except that this Section 5.6 shall not apply to (i)
Permitted Liens or (ii) the Security Interest; provided, however, that if,
notwithstanding this Section 5.6, any Lien to which this Section is applicable
shall be created or arise, all Obligations shall automatically be secured by
such Lien equally and ratably with the other Debt secured thereby, and the
holder of such other Debt, by accepting such Lien, shall be deemed to have
agreed thereto and to share with the Lenders, the Agent and the Letter of Credit
Issuers on that basis, the proceeds of such Lien, whether or not the lender's
Lien shall be perfected, provided further, however, that notwithstanding such
equal and ratable securing and sharing, the existence of such Lien shall
constitute a default in the performance or observance of this Section 5.6.

         Section 5.7 Merger, Consolidation, Acquisitions and Disposition of
Assets. (a) Subject to the provisions of subsection (b) below and unless the
Required Lenders shall, in their



<PAGE>   35



sole discretion, otherwise give their prior written consent, (i) Merge or
consolidate with any Person, provided that, if after giving effect thereto no
Default would exist, this Section 5.7 shall not apply to (A) any merger or
consolidation of the Borrower with any Subsidiary, so long as the Borrower shall
be the continuing entity, or (B) any merger or consolidation of any Subsidiary
with any other Subsidiary if, after giving effect thereto, the continuing entity
is a Wholly-Owned Subsidiary of the Borrower that has no Liabilities other than
Permitted Debt, (ii) purchase, lease or otherwise acquire for cash, stock or
other consideration all or any substantial portion of the assets of any other
Person (which for the purposes of this Section shall mean (x) more than 5% of
the gross assets of such Person or (y) any business line, product line or brand
name, but shall not include the purchase of inventory in the ordinary course of
business), or (iii) sell, lease, transfer or otherwise dispose of any assets,
provided that this Section 5.7 shall not apply to (x) the creation of a
Permitted Lien, (y) any purchase or disposition of inventory or investments
permitted by Section 5.13(c) in the ordinary course of business or (z) the
disposition of any obsolete or retired property not used or useful in its
business the fair market value of which obsolete or retired property, singly or
when aggregated with all other such assets sold in any Fiscal Year, does not
exceed $250,000.

                  (b)   Following the date that the Borrower shall receive no
less than $50,000,000 in Net Proceeds from the IPO, the Borrower may acquire the
stock or assets of another Person (including but not limited to brand names or
product lines) without the consent of the Required Lenders, notwithstanding
clause (ii) of subsection (a) above, for an aggregate consideration (whether
paid in cash, securities, property, assumption of liabilities or otherwise) not
to exceed an amount equal to the net proceeds from the IPO, subject to the
following criteria:

                  (i)   the assets acquired (including but not limited to brand
         names or product lines) or the business of the entity whose stock is
         acquired shall be in the Borrower's current line of business or in a

                  (ii)  the value of the total consideration to be paid or
         provided by the Borrower and/ or its Subsidiaries for such acquisition
         (other than an acquisition of assets constituting a brand name or
         product line), whether in cash, securities or assumption of liabilities
         shall not exceed $25,000,000;

                  (iii) immediately before and after giving effect to such
         acquisition no Default shall have occurred or be continuing, and

                  (iv)  (x) in the case of any acquisition, and (y) in the case
         of any acquisition of assets constituting a brand name or a product
         line where the total consideration shall exceed $10,000,000, the
         Borrower shall provide the Agent with a certificate that: (A) such
         acquisition complies with the terms hereof, (B) immediately before and
         after



<PAGE>   36



         giving effect to such acquisition no Default shall have occurred or be
         continuing, and (C) demonstrating compliance with the financial
         covenants contained herein on a pro forma basis as of the most recently

in such financial statements or in Schedule 4.3, as at September 30, 1997,

position of the Borrower and its Subsidiaries, as at their respective dates and
the consolidated earnings, shareholders' equity, and consolidated cash flows of
the Borrower and its Subsidiaries for the respective periods to which such
statements relate (subject, in the case of the financial statements delivered
pursuant to Section 6.1(a), to the absence of footnotes and normally recurring
year-end adjustments), and the furnishing of the same to the Lenders shall
constitute a representation and warranty by the Borrower made on the date the
same are furnished to the Lenders to that effect and to the further effect that,
except as disclosed or reflected in such financial statements, as at the
respective dates thereof, neither the Borrower nor any of its Subsidiaries had
any liability, contingent or otherwise, nor any unrealized or anticipated loss,
that, singly or in aggregate, has had or might have a Materially Adverse Effect
on the Borrower and its Subsidiaries, taken as a whole.

warrants to the Lenders, the Agent and Letter of Credit Issuers that all

                                       8.

                            CHANGES IN CIRCUMSTANCES

         Section 8.1 Mandatory Suspension and Conversion of Eurodollar Rate
Loans. Any Lender's obligations to make or continue Loans as, or to convert
Loans into, Eurodollar Loans shall be suspended, all outstanding Eurodollar
Loans shall be converted on the last day of their applicable Interest Periods
(or, if earlier, in the case of clause (b) below, on the last day such Lender
may lawfully continue to maintain Loans of that Type or, in the case of clause
(c) below, the day determined by such Lender to be the last Business Day before
the effective date of the applicable restriction) into, and all pending requests
for the making or continuation of or conversion, into Loans of that Type shall
be deemed requests for, Base Rate Loans, if:

                  (a) on or prior to the determination of an interest rate for a
Eurodollar Loan for any Interest Period, the Agent reasonably determines that
for any reason the Eurodollar Rate cannot be determined as provided herein, or
any Lender shall reasonably determine that such Rate would not accurately
reflect the cost to such Lender of making or continuing a Loan as, or converting
a Loan into, a Eurodollar Loan for such Interest Period;

                  (b) at any time such Lender reasonably determines that any
Regulatory Change makes it unlawful or impracticable for such Lender to make or
maintain any Eurodollar Loan, or to comply with its obligations hereunder in
respect thereof; or

                  (c) such Lender reasonably determines that by reason of any
Regulatory Change it is restricted, directly or indirectly, in the amount that
it may hold of (A) a category of liabilities that includes deposits by reference
to which, or on the basis of which, the interest rate applicable to Eurodollar
Loans is directly or indirectly determined, or (B) the category of assets which
includes Eurodollar Loans.

The Agent or any such Lender, as the case may be, shall promptly notify the
Borrower and the other parties to this Agreement of any circumstances that would
make the provisions of this Section 8.1 applicable, but the failure to give any
such notice shall not affect such Lender's rights hereunder.

         Section 8.2 Regulatory Changes. (a) If any Regulatory Change:

                  (i) shall subject the Agent, any Letter of Credit Issuer or
         any Lender to any Tax, duty or other charge reasonably determined by
         the Agent, such Letter of Credit Issuer or such Lender, as the case may
         be, to be applicable to any Extension of Credit, to its obligation to
         make or maintain any such Extension of Credit, or to this Agreement,
         any Note or any other Loan Document, or shall, in the reasonable



<PAGE>   51



         determination of the Agent, or any Lender, as the case may be, change
         the basis of taxation of payments to such Lender or the Agent on the
         principal of or interest on any Eurodollar Loan or of any other amounts
         payable under this Agreement in respect of any Eurodollar Loan or its
         obligation to make or maintain any Eurodollar Loan; or

                  (ii) shall impose, increase, modify or deem applicable any
         reserve, special deposit, assessment, or other requirement or condition
         against assets of, deposits with or to the account of, Extensions of
         Credit by, or the Commitment or obligations of, any Lender, any Letter
         of Credit Issuer or the Agent, or shall impose on the Agent or such
         Lender or on any relevant interbank market for Dollars, any condition;

and the result of the foregoing, in the reasonable determination of the Agent,
such Letter of Credit Issuer or such Lender, as the case may be, is (x) to
reduce the amount of any sum received or receivable by such Lender with respect
to any Eurodollar Loan or the return to be earned by the Agent, such Letter of
Credit Issuer, or such Lender on any Extension of Credit, (y) to impose a cost
or increase any existing cost on the Agent, such Letter of Credit Issuer, or
such Lender, as the case may be, or any parent company of the Agent, such Letter
of Credit Issuer, or such Lender, that is attributable to the making or
maintaining of any Extension of Credit or its Commitment or its obligation to
make any Extension of Credit, or (z) to require the Agent, such Letter of Credit
Issuer, or such Lender, or any parent company of the Agent, such Letter of
Credit Issuer, or such Lender, to make any payment on or calculated by reference
to the gross amount of any amount received by it hereunder, under any Loan
Document or under any Note, then, within 15 days after request by the Agent,
such Letter of Credit Issuer, or such Lender, the Borrower shall pay to the
Agent, such Letter of Credit Issuer, or such Lender such additional amount or
amounts as the Agent, such Letter of Credit Issuer, or such Lender reasonably
determines will compensate it, or its parent company, for such reduction,
increased cost or payment. The Agent, such Letter of Credit Issuer, or any such
Lender, as the case may be, will promptly notify the Borrower of any Regulatory
Change of which it has knowledge and that will entitle the Agent, such Letter of
Credit Issuer, or such Lender to compensation pursuant to this Section 8.2, but
the failure to give such notice shall not affect the Agent, such Letter of
Credit Issuer, or such Lender's right to such compensation.

                  (b) If after the date hereof the Agent, any Letter of Credit
Issuer, or any Lender shall have reasonably determined that the adoption or
implementation of any applicable law, rule or regulation regarding capital
adequacy, or any change therein or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by it (or its Applicable Lending Office) with any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on capital of such Person (or its parent) as a consequence of
such Person's obligations



<PAGE>   52



hereunder or obligations held by it, including, without limitation its
Commitments, Loans and participation interests in Letters of Credit to a level
below that which such Person (or its parent) could have achieved but for such
adoption, change or compliance (taking into consideration its policies with
respect to capital adequacy) by an amount deemed by such Lender to be material,
then from time to time, within 15 days after demand by such Person (with a copy
to the Agent), the Borrower shall pay to such Person such additional amount or
amounts as will compensate such Person (or its parent) for such reduction.

         Section 8.3 Change of Lending Office. Any Lender will, if an event
occurs with respect to a Lending Office that makes Section 8.1 or 8.2
applicable, and if requested by the Borrower, use reasonable efforts to
designate another Lending Office or Offices, provided that such designation
would not, in the sole and absolute discretion of such Lender, be
disadvantageous to such Lender in any manner or contrary to such Lender's
policy. Any Lender may at any time and from time to time change any Lending
Office and shall give notice of any such change to the Borrower. Except in the
case of a change in Lending Offices made at the request of the Borrower, the
designation of a new Lending Office by a Lender shall not make operable the
provisions of clause (ii) or (iii) of Section 8.1 or entitle such Lender to make
a claim under Section 8.2 if the operability of such clause or such claim
results solely from such designation and not from a subsequent Regulatory
Change.

         Section 8.4 Funding Losses. The Borrower shall pay to the Agent and
each Lender, upon request, such amount or amounts as such Person determines are
necessary to compensate it for any loss, cost or expense incurred by it as a
result of (i) any payment, prepayment, conversion or continuation of a
Eurodollar Loan on a date other than the last day of an Interest Period for such
Eurodollar Loan or (ii) a Eurodollar Loan for any reason not being made or
converted after the Borrower shall have given a Notice of Borrowing, or any
payment of principal of or interest thereon not being made on the date therefor
determined in accordance with the applicable provisions of this Agreement, in
each case whatever the reason for such event, including, without limitation, the
operation of Sections 1.6, 1.7, 7.2 or otherwise. In the case of a Eurodollar
Loan, at the election of such Lender, and without limiting the generality of the
foregoing, but without duplication, such compensation on account of losses
referred to in (i) and (ii) above may include an amount equal to the excess of
(x) the interest that would have been received from the Borrower under this
Agreement on any amounts to be reemployed during an Interest Period or its
remaining portion over (y) the interest component of the return that such Lender
determines it could have obtained had it placed such amount on deposit in the
London interbank market for a period equal to such Interest Period or its
remaining portion.

         Section 8.5 Determinations. In making the determinations contemplated
by Sections 8.1, 8.2 and 8.4, the Agent, the Letter of Credit Issuers, and the
Lenders may make such reasonable estimates, assumptions, allocations and the
like that they, in good faith, reasonably determine to be appropriate, but a
Lender's, the Letter of Credit Issuers' or the Agent's selection thereof in
accordance with this Section 8.5, and the determinations made by a Lender, the
Letter of Credit Issuers, or the Agent on the basis thereof, shall be presumed
correct absent convincing evidence to the contrary. Any such Lender, Letter of
Credit Issuer or the Agent, as the case may be, shall furnish to the Borrower


<PAGE>   53


upon request a certificate outlining in reasonable detail the computation of any
amounts claimed by it under this Article VIII and the assumptions underlying
such computations.

                                       9.

             THE ADMINISTRATIVE AGENT AND THE LETTER OF CREDIT BANKS

         Section 9.1 Appointment and Authorization.

                  (a) Each Lender irrevocably appoints and authorizes the Agent
to take such action as agent on its behalf and to exercise such powers under
this Agreement, the Notes, the Security Documents and the Letters of Credit as
are delegated to the Agent by the terms hereof or thereof, together with all
such powers as are reasonably incidental thereto.

                  (b) Each Lender irrevocably authorizes each Letter of Credit
Issuer to issue the Letters of Credit as provided in this Agreement, and to take
all other actions specifically delegated to it under this Agreement and the
Reimbursement Agreements to which it is a party and as are reasonably incidental
thereto.

         Section 9.2 Agent and Affiliates; Letter of Credit Issuer and
Affiliates. (a) GECC shall have the same rights and powers under this Agreement
and the Loan Documents as any other Lender and may exercise or refrain from
exercising the same as though it were not the Agent and GECC and its affiliates
may accept deposits from, lend money to, and generally engage in any kind of
business with the Borrower, or any Subsidiary or Affiliate of the Borrower as if
it were not the Agent hereunder.

                  (b) Each Letter of Credit Issuer, acting in its individual
capacity, shall have the same rights and powers under this Agreement and the
other Loan Documents, and may exercise, or refrain from exercising such rights
as though it were not a Letter of Credit Issuer hereunder, and its affiliates
may accept deposits from, lend money to, and generally engage in any kind of
business with the Borrower or any Subsidiary or Affiliate of the Borrower as if
it were not a Letter of Credit Issuer hereunder.

         Section 9.3 Action by Agent and Letter of Credit Issuer. The respective
obligations hereunder of the Agent and of the Letter of Credit Issuers are only
those expressly set forth herein. Without limiting the generality of the
foregoing, the Agent shall not be required to take any action with respect to
any Default, except as requested by the Required Lenders. The Agent and the
Letter of Credit Issuers shall in all cases be fully protected in acting or in
refraining from acting hereunder and under the other Loan Documents in
accordance with the written instructions signed by the Required Lenders and each

                  (iii)    If to a Letter of Credit Issuer at its respective
         address and telex, telecopier and telephone numbers set forth in the
         Reimbursement Agreement to which such Letter of Credit Issuer is a
         party;

                  (iv)     If to the Lenders, at their respective address and

                  (c)      Effectiveness. Each notice and other communication

unavailable at the time, to any other responsible officer of the Borrower,
except that notices of a change of address, telex, telecopier or telephone
number, and notices to the Agent shall not be effective, and materials furnished
to the Lenders pursuant to Article VI shall not be deemed furnished until
received, and in the case of the Agent, such notices and materials shall not be
deemed received until physically received by a responsible officer at the office
of the Agent set forth above, not later than noon (New York City time) on any

adequacy of any notice to the Agent hereunder. Notices under Sections 1.2, 2.2,
2.3, and 7.2 may be by telephone, promptly confirmed in writing (which shall
include communications by telex and telecopy). The failure by the Agent to give
written confirmation of any such notice shall not effect the validity thereof.
In the event of a discrepancy between telephonic notice and the written
confirmation thereof, or in the event written confirmation of such notice is not
furnished, the telephonic notice as understood by the Agent will be deemed the
effective notice.

         Section 11.2 Expenses; Indemnification. Whether or not any Extension of
Credit is made hereunder, the Borrower shall, on demand, pay or reimburse the
Lenders, the Agent and the Letter of Credit Issuers for (a) all transfer,
documentary, stamp and similar taxes, and all search, recording and filing fees,
if any, payable in connection with, arising out of or in any way related to the
execution, delivery and performance of this Agreement, the other Loan Documents
or the Extensions of Credit, and (b) all reasonable costs and expenses
(including fees and disbursements of legal counsel and other experts) incurred,
and all payments made, and indemnify and hold the Lenders, the Agent and the
Letter of Credit Issuers harmless from and against all losses suffered, in
connection with, arising out of, or in any way related to (i) the negotiation,
preparation, execution and delivery of (A) this Agreement and the other Loan
Documents, (B) any Extension of Credit and (C) (whether or not executed) any
waiver, amendment or consent hereunder or thereunder, or hereto or thereto, (ii)
the administration of this Agreement and the other Loan Documents, including
without limitation the matters set forth in Section 6.3(b)(iv) (other than
ordinary course overhead associated with regular employees of the Agent incurred
in the ordinary course of the administration of this Agreement absent an Event
of Default), (iii) consulting with respect to any matter in any way arising out
of, relating to, or connected with, this Agreement or any of the other Loan
Documents, including, but not limited to, the enforcement by the Lenders, the
Agent or the Letter of Credit Issuers of any of their rights hereunder or under
any of the other Loan Documents, or the performance by the Lenders, the Agent or
the Letter of Credit Issuers of any of their obligations hereunder or under any
other Loan Document, if any, (iv) protecting, preserving, exercising or
enforcing any of the rights of the Lenders, the Agent or the Letter of Credit
Issuers hereunder or under any of the other Loan Documents, (v) any claim
(whether asserted by the Lenders, the Agent, the Letter of Credit Issuers, the

performance and observance in full of the Borrower's obligations hereunder and
under the other Loan Documents) and the prosecution or defense thereof, in any
way arising under, related to, or connected with, this Agreement, or any of the
other Loan Documents or the relationship established hereunder or under the
other Loan Documents, and



<PAGE>   84



(vi) any governmental investigation arising out of, relating to, or in any way
connected with this Agreement or any of the other Loan Documents, provided that
the foregoing indemnity shall not be applicable to any loss suffered by any
Lender, the Agent or a Letter of Credit Issuer to the extent such loss is
determined by a judgment of a court that is binding on such Lender, the Agent or
such Letter of Credit Issuer, final and not subject to review on appeal, to be
the result of acts or omissions of such Lender, the Agent or such Letter of
Credit Issuer, constituting (x) gross negligence or willful misconduct, (y)
violations of law, or (z) its failure to observe any other standard expressly
applicable to it under any of the other provisions of this Agreement or any of
the other Loan Documents. The Agent shall have the right to charge any account
of the Borrower for amounts due under this Section, and may cause the Borrower
to incur a Borrowing in such amounts as may be necessary to repay such
Obligations.

         Section 11.3 Rights Cumulative. The rights and remedies of the Lenders,
the Agent and the Letter of Credit Issuers under this Agreement and the other
Loan Documents shall be cumulative and not exclusive of, nor limiting upon, any
rights or remedies that they would otherwise have, and no failure or delay by
any Lender, the Agent or any Letter of Credit Issuer in exercising any right
shall operate as a waiver of it, nor shall any single or partial exercise of any
power or right preclude its other or further exercise or any other power or
right.

         Section 11.4 Disclosure. The Agent, the Lenders and the Letter of
Credit Issuers may disclose to, and exchange and discuss with, any other Person
any information concerning the Borrower and any of its Subsidiaries (whether
received by the Agent, the Letter of Credit Issuers, the Lenders or such person
in connection with or pursuant to this Agreement or otherwise) only (i) as may
be required by Applicable Law, (ii) for the purpose of protecting, preserving,
exercising or enforcing any rights hereunder or under any of the other Loan
Documents, or consulting with respect to any such rights or any rights of the
Borrower or (iii) as reasonably required in connection with the making of
assignments and the sale of participations by the Lenders as provided in Section
11.7.

         Section 11.5 Waivers; Amendments. (a) Any term, covenant, agreement or
condition of this Agreement or any Loan Document may be amended with the consent
of the Borrower, the Agent and the Required Lenders, or compliance therewith may
be waived in writing by the Agent and, in the case of a term, covenant,
agreement or condition contained in any Reimbursement Agreement, the Letter of
Credit Issuer party thereto, when authorized by the Required Lenders, and in any
such event, the failure to observe, perform or discharge any such covenant,
condition or obligation (whether such amendment is executed or such consent or
waiver is given before or after such failure) shall not be construed as a breach
of such covenant, condition or obligation or a Default hereunder, provided that
no such amendment, consent or waiver shall:

                  (i) affect the amount or extend the time of the Commitment of
         any Lender, of the obligation of any Letter of Credit Issuer to issue
         Letters of Credit or extend the expiration date of any Letter of
         Credit, or of the obligation of the Agent, any Letter of Credit Issuer
         or any Lender to pay amounts on account of Loans or Letters of Credit,
         and thereby extend credit to the Borrower, without the prior written
         consent of such Lender, such Letter of Credit Issuer or the Agent, as
         the case may be;



<PAGE>   85



                  (ii)  alter the time or times of payment of the principal of
         or interest on any Obligation or with respect to any participation in a
         Letter of Credit or any fees payable hereunder or any Loan Document, or
         the amount of the principal of any Note, Reimbursement Obligation or
         Letter of Credit, or the rates of interest, commission or fees, or
         permit any subordination of principal, interest, or fees hereunder or
         any Loan Document, without the prior written consent of the Lender,
         Letter of Credit Issuer or Agent as to its interest in the
         corresponding Obligation, participation interest, commission or fees;

                  (iii) alter any provision requiring the ratable application of
         amounts received by the Agent in payment of, or for application on,
         indebtedness under this Agreement or under any of the Notes or any
         other Loan Document or any Obligation or Letter of Credit Obligation,
         or change the parties or percentages required to authorize or direct
         the taking of any action under this Agreement or any Loan Document,
         without the prior written consent of the Agent and all the Lenders and,
         to the extent such change adversely affects a Letter of Credit Issuer,
         the prior written consent of such Letter of Credit Issuer;

                  (iv)  release all or substantially all of the Collateral or
         reduce the Security Interest, or change the definition of "Borrowing
         Base" or any component thereof, without the prior written consent of
         all the Lenders; or

                  (v)   amend any term or provision of Article IX or Section 
         11.2 or any waiver, release or limitation of liability in favor of the
         Agent or the Letter of Credit Issuer contained herein or in any other
         Loan Document without the prior written consent of the Agent and, to
         the extent the rights or obligations of any Letter of Credit Issuer are
         adversely affected thereby, the prior written consent of such Letter of
         Credit Issuer.

Except as set forth in this Section, each Letter of Credit Issuer agrees to act
upon the direction of the Required Lenders in all respects under its respective
Reimbursement Agreement. In addition to the foregoing rights, for the purpose of
this Section, the Letter of Credit Issuer shall be deemed to own and be entitled
to vote in an amount equal to the participation interest of any Lender that has
failed to pay any amount owing to the Letter of Credit Issuer hereunder.

                  (b)   Unless otherwise specified in such waiver or consent, a
waiver or consent given hereunder shall be effective only in the specific
instance and for the specific purpose for which given.

         Section 11.6   Set-Off.

                  (a)   Exercise of Set-Off Rights. Upon the occurrence and
during the continuance of any Event of Default, each of the Agent, the Letter of
Credit Issuers and the Lenders, and each of its branches and offices, is hereby
authorized by the Borrower, at any time and from time to time, without notice to
the Borrower, (i) to set-off against, and to appropriate and apply to the
payment of the Obligations (whether matured or unmatured, fixed or contingent or
liquidated or unliquidated), any and all amounts owing by the Agent, such Letter
of Credit Issuer or such



<PAGE>   86



Lender, or any such office or branch, to the Borrower (whether payable in
Dollars or any other currency, whether matured or unmatured, and, in the case of
deposits, whether general or special time or demand and however evidenced) and
(ii) pending any such action, to the extent necessary, to hold such amounts as
collateral to secure such Obligations and to return as unpaid for insufficient
funds any and all checks and other items drawn against any deposits so held as
such Person in its sole discretion may elect. The Borrower agrees, to the
fullest extent it may effectively do so under Applicable Law, that any holder of
a participation in any Extension of Credit may exercise rights of set-off and
counterclaim and other rights with respect to such participation as fully as if
such holder of a participation were a direct creditor of the Borrower in the
amount of such participation. The Agent, each Letter of Credit Issuer and each
Lender agrees to give the Borrower prompt notice following its exercise of any
set-off pursuant to this Section, but the failure to give such notice shall not
affect the effectiveness of such exercise.

                  (b) Sharing of Set-Offs. Each of the Agent, the Letter of
Credit Issuers and the Lenders agree that if it shall, by exercising any right
of set-off or counterclaim or otherwise, obtain any payment (whether voluntary
or involuntary), of a proportion of the Obligations held by it that is greater
than the proportion received by any other of them in respect of the Obligations
held by such other of them, the Agent, the Letter of Credit Issuer and/or the
Lender, as the case may be, receiving such proportionately greater payment shall
purchase such participations in the Obligations held by the other of them, and
such other adjustments shall be made, as may be required so that all such
payments in respect of the Obligations shall be shared by all of them pro rata.
Any party receiving such proportionately greater payment shall immediately
notify the Agent thereof. Promptly upon its receipt of such notice, the Agent
shall notify each of the Lenders and the Letter of Credit Issuers of the amount
or amounts received by one or more of the Lenders in excess of its Proportionate
Share thereof. On the immediately succeeding Business Day after the giving of
such notice by the Agent, the appropriate adjustments in the Obligations shall
be made as provided in this Section 11.6(b).

                  (c) No Impairment of Set-Off Rights. Nothing in subsection (b)
of this Section 11.6 shall impair the right of the Agent, any Letter of Credit
Issuer or any Lender to exercise any right of set-off or counterclaim it may
have, or to otherwise obtain payment, and to apply such amount to the payment of
indebtedness other than the Obligations.

         Section 11.7 Assignment and Participations.

                  (a) Assignments. The Borrower may not assign or transfer any
of its rights or obligations under this Agreement without the prior written
consent of the Agent and all the Lenders, and no such assignment or transfer of
any such obligations shall relieve the Borrower thereof unless the Lenders shall
have consented to such release in a writing specifically referring to the
obligation from which the Borrower is to be released. Any Lender may assign its
rights and delegate its obligations under this Agreement and the other Loan
Documents and further may assign, all or any part of any Extensions of Credit
made by it, or its Commitment or any other



<PAGE>   87



interest herein or in any other Loan Documents to another bank or entity;
provided, that, except in the case of an assignment by a Lender to one of its
branches or its affiliates, (i) the Agent and each Letter of Credit Issuer shall
have consented in writing to such assignment and the terms thereof, including
the amount of such assignment and the assignee thereof, but which consent shall
not be unreasonably withheld, (ii) the Agent shall have received a $5,000
assignment fee from the assignor Lender, and (iii) the Agent shall have received
an Assignment and Assumption Agreement in the form of Schedule 11.7 duly
executed by the assignee, the assignor Lender and the Agent; and provided
further that except (A) in the case of an assignment by a Lender to one of its
branches or affiliates or (B) in the case of an assignment to a bank, a fund or
an institutional investor with capital and surplus in excess of $300,000,000 or
any of whose securities are rated investment grade or above by any nationally
recognized rating service, the Borrower shall have given its prior written
consent which consent shall not be unreasonably withheld or delayed; as promptly
as practicable following its becoming a Lender hereunder, each assignee shall
notify the Borrower thereof and provide the Borrower with a copy thereof. Upon
any such assignment by a Lender pursuant to the terms hereof, the assignee
thereof shall have, to the extent of such assignment (unless otherwise provided
therein) the same rights and benefits as it would have if it were an original
Lender hereunder and under the Loan Documents, and such assignee shall assume
all of the obligations of a Lender hereunder and such assignor Lender shall be
released from its obligations hereunder to a corresponding extent, and no
further consent or action by any party shall be required to effect such
assignments, assumptions and corresponding releases.

                  (b) Participations. Any Lender may from time to time sell or
otherwise grant participations in the Extensions of Credit, and the holder of
any such participation, if the participation agreement so specifically provides,
shall be entitled to all of the rights of a Lender hereunder respecting the
taking of any action directly affecting the extension of the final maturity of
the principal amount of, or any payment date for any interest on, a Loan
allocated to such participation, the reduction in the principal amount of, or
the rate of interest payable on, the Loans, the release of all or substantially
all of the Collateral, or the enforcement of the Obligations. Except as provided
in the preceding sentence and as provided in Article VIII or Section 11.6, a
holder of a participation shall not be deemed a Lender.

                  (c) Requirements Upon Transfer. If, pursuant to this
subsection, any interest in this Agreement or any Loan Document is transferred
to any assignee that is organized under the laws of any jurisdiction other than
the United States or any state thereof, the transferor Lender shall cause such
assignee concurrently with the effectiveness of such transfer, (i) to represent
to the transferor Lender (for the benefit of the transferor Lender, the Agent,
the Letter of Credit Issuers and the Borrower) that it is either (x) entitled to
the benefits of an income tax treaty with the United States that provides for an
exemption from United States withholding tax on interest and other payments
which may be made by the Borrower to other Loan Document; or (y) is engaged in
the trade or business within the United States, (ii) to furnish to the
transferor Lender, the Agent, the Letter of Credit Issuers and the Borrower
either U.S. Internal Revenue Service Form 4224 or U.S. Internal Revenue Service
Form 1001 (wherein such assignee claims entitlement to complete



<PAGE>   88



exemption from U.S. federal withholding tax on all payments hereunder) and (iii)
to agree (for the benefit of the transferor Lender, the Agent, the Letter of
Credit Issuers and the Borrower) to provide to the transferor Lender, the Agent,
the Letter of Credit Issuers and the Borrower a new Form 4224 or Form 1001 upon
the obsolescence of any previously delivered form and comparable statements in
accordance with applicable U.S. laws and regulations with regard to such
withholding tax exemption.

                  (d) Lender Covenants. Each Lender represents and warrants to
the Borrower, the Letter of Credit Issuers and the Agent that it is either (x) a
United States person (as defined in Section 7701(a)(30) of the Code); (y)
entitled to the benefits of an income tax treaty with the United States that
provides for an exemption from United States withholding tax on interest and
other payments which may be made by the Borrower to such Lender pursuant to the
terms of this Agreement or any other Loan Document; or (z) engaged in trade or
business within the United States. Each Lender that is organized under the laws
of any jurisdiction other than the United States or any State thereof (including
the District of Columbia) agrees to furnish to the Agent, the Letter of Credit
Issuers and the Borrower, prior to the date of the first interest payment
hereunder, two copies of either U.S. Internal Revenue Service Form 4224 or U.S.
Internal Revenue Service Form 1001 (wherein such Lender claims entitlement to
complete exemption from U.S. federal withholding tax on all payments hereunder)
and to provide to the Agent, the Letter of Credit Issuers and the Borrower a new
Form 4224 or Form 1001 upon the obsolescence of any previously delivered form
and comparable statements in accordance with applicable U.S. laws and
regulations and amendments duly executed and completed by such Lender, and to
comply from time to time with all applicable U.S. laws and regulations with
regard to such withholding tax exemptions.

         Section 11.8 Governing Law. THIS AGREEMENT SHALL BE EFFECTIVE UPON
ACCEPTANCE BY THE LENDERS IN GEORGIA, AND THE AGREEMENT AND THE OTHER LOAN
DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAW OF THE

PROCEEDING BROUGHT AGAINST THE BORROWER WITH RESPECT TO THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENTS, MAY BE BROUGHT IN ANY COURT OF COMPETENT JURISDICTION IN
THE CITY OF ATLANTA, STATE OF GEORGIA, AND, BY EXECUTION AND DELIVERY OF THIS
AGREEMENT, THE BORROWER (A) ACCEPTS, GENERALLY AND UNCONDITIONALLY, THE
NONEXCLUSIVE JURISDICTION OF SUCH COURTS AND ANY RELATED APPELLATE COURT, AND
IRREVOCABLY AGREES (WITHOUT WAIVING ANY RIGHT TO APPEAL) TO BE BOUND BY ANY
JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS, AND (B) IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE

OR THAT SUCH COURT IS AN INCONVENIENT FORUM (WITHOUT WAIVING ANY RIGHT THE



<PAGE>   89



BORROWER MAY HAVE TO REMOVE ANY SUCH JUDICIAL PROCEEDING TO THE UNITED STATES
DISTRICT COURT LOCATED IN THE CITY OF ATLANTA, STATE OF GEORGIA). THE BORROWER
HEREBY WAIVES, PERSONAL SERVICE OF PROCESS AND CONSENTS THAT SERVICE OF PROCESS
UPON IT MAY BE MADE BY CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT REQUESTED,
(WITH A COPY BY OVERNIGHT COURIER), AT ITS ADDRESS SPECIFIED OR DETERMINED IN
ACCORDANCE WITH THE PROVISIONS OF SECTION 11.1, AND SERVICE SO MADE SHALL BE
DEEMED COMPLETED ON THE FIFTH DAY AFTER SUCH SERVICE IS DEPOSITED IN THE MAIL.
NOTHING HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF THE AGENT, ANY LETTER OF CREDIT
ISSUER OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER IN THE COURTS OF
ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE BORROWER AGAINST THE
LENDERS, THE AGENT OR THE LETTER OF CREDIT BANKS, INVOLVING, DIRECTLY OR

ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING
OUT OF, RELATED TO, OR CONNECTED WITH THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS
OR THE RELATIONSHIP ESTABLISHED HEREUNDER OR THEREUNDER AND WHETHER ARISING OR
ASSERTED BEFORE OR AFTER THE AGREEMENT DATE OR BEFORE OR AFTER PAYMENT,
OBSERVANCE AND PERFORMANCE IN FULL OF THE BORROWER'S OBLIGATIONS HEREUNDER OR
THEREUNDER.

         Section 11.10 Severability of Provisions. Any provision of this
Agreement which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction. To the extent permitted by Applicable Law, the Borrower hereby
waives any provision of law that renders any provision hereof prohibited or
unenforceable in any respect.

         Section 11.11 Counterparts. This Agreement may be executed in any
number of counterparts, all of which shall be deemed to constitute but one
original and shall be binding upon all parties, their successors and permitted
