          time to time, being the "Credit Agreement", and the terms defined
          therein and  not otherwise  defined herein  being used herein  as

               WHEREAS, it is a condition precedent  to the Initial Funding
          Date  under the Credit Agreement that  the Parent Guarantor shall
          have executed and delivered this Guaranty;

               NOW,  THEREFORE, in  consideration  of the  premises and  in
          order to  induce the  Banks to  make the  loans under the  Credit
          Agreement, the  Parent Guarantor  hereby agrees as  follows (with
          terms being used as defined in Section 15):

               SECTION  1.     Guaranty.    The   Parent  Guarantor  hereby
          unconditionally and  irrevocably guarantees the  punctual payment
          when  due,  whether  at   stated  maturity,  by  acceleration  or
          otherwise, of all  obligations of the  Borrower now or  hereafter
          existing under  the Loan  Documents, whether for  borrowed money,
          interest, fees or any other  amounts due thereunder or  otherwise
          (the   "Guaranteed  Obligations")   and  any  and   all  expenses
          (including counsel fees and  expenses) reasonably incurred by any
          Guaranteed Party in enforcing any rights under this Guaranty.

               SECTION  2.    Guaranty  Absolute.    The  Parent  Guarantor
          guarantees  that  the  obligations   will  be  paid  strictly  in
          accordance with the  terms of the  Loan Documents, regardless  of
          any law,  regulation or order now  or hereafter in effect  in any
          jurisdiction affecting any  of such  terms or the  rights of  any





          Guaranteed Party  with respect  thereto.   The  liability of  the
          Parent  Guarantor  under  this  Guaranty shall  be  absolute  and
          unconditional irrespective of:

               (a)  any  lack of  validity  or enforceability  of the  Loan
          Documents  (including this  Guaranty) or  any other  agreement or
          instrument relating thereto;

               (b)  any  change in the time, manner or place of payment of,
          or  in  any  other  term  of,  all   or  any  of  the  Guaranteed
          Obligations, or any other  amendment or waiver of or  any consent
          to departure from the Loan Documents;

               (c)  any   exchange,  release   or   nonperfection  of   any
          collateral, or any release  or amendment or waiver of  or consent
          to departure  from  any other  guaranty, for  all or  any of  the
          Guaranteed Obligations; or

               (d)  any other circumstance which might otherwise constitute
          a defense  available to, or  a discharge  of, the Borrower,  or a
          guarantor.

               SECTION  3.  Waiver.  The Parent Guarantor hereby waives all
          notices with  respect to  any of the  Guaranteed Obligations  and
          this  Guaranty  and any  requirement  that  any Guaranteed  Party
          protect, secure, perfect or insure any security interests or lien
          on any property subject thereto or exhaust any  right or take any
          action against the Borrower, or any other person or entity or any
          collateral.

               SECTION 4.  Subrogation.  (a) The Parent Guarantor shall not
          exercise  any rights  which  it  may  have  acquired  by  way  of
          subrogation under this Guaranty, by any payment made hereunder or
          otherwise nor  shall the Parent Guarantor  seek any reimbursement
          from  the  Borrower in  respect of  payments  made by  the Parent
          Guarantor  hereunder,  unless and  until  all  of the  Guaranteed
          Obligations  shall have been paid and discharged, in full, and if
          any payment shall be made  to the Parent Guarantor on account  of
          such subrogation  or reimbursement  rights at  any time  when the
          Guaranteed Obligations  shall not have been  paid and discharged,
          in full, each and every amount so paid shall forthwith be paid to
          the Agent  to  be credited  and  applied against  the  Guaranteed
          Obligations, whether matured or unmatured.

               (b)  If, pursuant  to Applicable Law, the  Parent Guarantor,
          by payment  or otherwise, becomes subrogated to all or any of the
          rights of the Guaranteed Parties under any of the Loan Documents,
          the  rights  of  the  Guaranteed  Parties  to  which  the  Parent
          Guarantor shall be  subrogated shall  be accepted  by the  Parent
          Guarantor  "as is" and without any  representation or warranty of
          any  kind by  the Guaranteed  Parties,  express or  implied, with
          respect to the legality, value, validity or enforceability of any

                                        - 2 -





          of   such  rights,   or  the   existence,  availability,   value,
          merchantability  or fitness  for  any particular  purpose of  any
          collateral  and  shall  be  without recourse  to  the  Guaranteed
          Parties.

               SECTION  5.   Representations  and Warranties.   The  Parent
          Guarantor hereby represents and warrants as follows:

               (a)  Incorporation  and   Good  Standing.    It   is  (i)  a
          corporation  duly  incorporated,  validly existing  and  in  good
          standing  under the laws of the  State of Delaware; and (ii) duly
          qualified and in good standing as a foreign corporation under the
          laws  of each  other  jurisdiction in  which  the failure  so  to
          qualify would have a Material Adverse Effect.

               (b)  Corporate  Power and  Authorization.    The  execution,
          delivery and performance by the Parent Guarantor of this Guaranty
          are  within the  Parent Guarantor's  corporate powers,  have been
          duly  authorized  by  all  necessary  corporate  action,  do  not
          contravene the  Parent Guarantor's charter or by-laws, any law or
          any contractual restriction binding  on or affecting and material
          to the  Parent Guarantor, and  do not  result in  or require  the
          creation  of  any  Lien  upon  or  with  respect  to  any  of its
          properties.

               (c)  Authorization.   No authorization, consent  or approval
          or  other  action  by,  and no  notice  to  or  filing  with, any
          Governmental Authority or regulatory body is required for the due
          execution, delivery  and performance  by the Parent  Guarantor of
          this  Guaranty,  other  than  (i)  consents,  authorizations  and
          approvals that have been  obtained, are final and not  subject to
          review on appeal or  to collateral attack, and are in  full force
          and effect and, in the case of any such required under Applicable

          7.2(a)(iv)  of the  Credit  Agreement, (ii)  notices, filings  or
          registrations  that have been  given or  effected, and  (iii) the

          Exchange Commission as exhibits to its public filings.

               (d)  Valid Guaranty.   This Guaranty is  a legal, valid  and
          binding obligation of the  Parent Guarantor, enforceable  against
          the Parent Guarantor  in accordance with its terms,  except where
          such  enforcement  may  be  limited  by  bankruptcy,  insolvency,
          reorganization,  moratorium  or  similar  laws  relating  to   or
          limiting  creditor's  rights  generally  or  equitable principles
          relating to enforceability.

               (e)  Litigation.   There is no pending  or threatened action
          or proceeding affecting the  Parent Guarantor or its Subsidiaries
          before any  court, governmental  agency or arbitrator,  in which,
          individually  or   in  the  aggregate,  there   is  a  reasonable


                                        - 3 -





          probability of an  adverse decision which  could have a  Material
          Adverse Effect or result in a Material Credit Agreement Change.

               (f)  Taxes.  All federal, and all  material state, local and
          foreign tax returns, reports and statements required to  be filed
          by  the Parent  Guarantor or  any of  its Subsidiaries  have been
          filed   with  the  appropriate   governmental  agencies   in  all
          jurisdictions in  which such returns, reports  and statements are
          required to  be  filed.   All consolidated,  combined or  unitary
          returns  which  include  the  Parent  Guarantor  or  any  of  its
          Subsidiaries  have been  filed with the  appropriate governmental
          agencies in all jurisdictions in  which such returns, reports and
          statements are required to  be filed except where such  filing is
          being  contested or  may  be contested.    All federal,  and  all
          material  state,  local  and  foreign taxes,  charges  and  other
          impositions  of the  Parent  Guarantor, its  Subsidiaries or  any
          consolidated, combined or unitary group which includes the Parent
          Guarantor  or any of its  Subsidiaries which are  due and payable
          have  been timely  paid prior  to  the date  on  which any  fine,
          penalty, interest, late charge  or loss may be added  thereto for
          non-payment thereof except  where contested in good  faith and by
          appropriate proceedings  if adequate reserves therefor  have been
          established  on  the  books  of  the  Parent  Guarantor  or  such
          Subsidiary  in accordance with GAAP.  Proper and accurate amounts
          have been withheld by  or on behalf of  the Parent Guarantor  and
          each of its Subsidiaries from  their respective employees for all
          periods in  full  and complete  compliance with  the tax,  social
          security  and unemployment  withholding provisions  of applicable
          federal, state,  local and foreign law and such withholdings have
          been timely paid to the  respective governmental agencies, in all
          material respects.  Neither  the Parent Guarantor nor any  of its
          Tax  Affiliates  has agreed  or has  been  requested to  make any
          adjustment under Section 481(a) of the Code by reason of a change
          in accounting method or otherwise relating to the Borrower or any
          of  its  Subsidiaries which  will affect  a  taxable year  of the
          Parent  Guarantor or a  Tax Affiliate  ending after  December 31,
          1993, which has  not been reflected  in the financial  statements
          delivered  pursuant to  Section  6(g)  and  which  would  have  a
          Material Adverse Effect.  The  Parent Guarantor has no obligation
          to  any Person other than the Borrower and the Parent Guarantor's
          Subsidiaries under any tax sharing agreement or other tax sharing
          arrangement.

          its   consolidated  Subsidiaries  as  of  such  respective  dates
          (subject,  in the case  of such reports on  Form 10-Q, to changes

               thereto.

               (h)  ERISA.

                    (i)    No liability under Sections 4062, 4063,  4064 or
               4069  of ERISA  has  been  or  is  expected  by  the  Parent
               Guarantor  to be  incurred  by the  Parent Guarantor  or any
               ERISA  Affiliate  with  respect  to  any  Plan  which  is  a
               Single-Employer Plan  in an amount that  could reasonably be
               expected to have a Material Adverse Effect.

                    (ii)   No Plan  which is a Single-Employer  Plan had an
               accumulated funding deficiency, whether or not waived, as of
               the last  day of  the most recent  fiscal year of  such Plan
               ended  prior  to  the  date  hereof.    Neither  the  Parent
               Guarantor nor  any ERISA Affiliate  is (A) required  to give
               security  to  any  Plan  which  is  a  Single-Employer  Plan
               pursuant to Section 401(a)(29) of the Code or Section 307 of
               ERISA, or  (B) subject  to a  Lien in favor  of such  a Plan
               under Section 302(f) of ERISA.

                    (iii)  Each Plan  of the Parent Guarantor,  each of its
               Subsidiaries  and  each  of   its  ERISA  Affiliates  is  in
               compliance  in  all material  respects  with  the applicable
               provisions  of ERISA and the Code,  except where the failure
               to comply would not result in any Material Adverse Effect.

                    (iv)   Neither  the Parent  Guarantor  nor any  of  its
               Subsidiaries has incurred a tax liability under Section 4975
               of the  Code or a penalty  under Section 502(i)  of ERISA in
               respect of any Plan  which has not been paid in full, except
               where the incurrence of such tax or penalty would not result
               in a Material Adverse Effect.

                    (v)    None  of  the  Parent  Guarantor,  any  of   its
               Subsidiaries  or   any  ERISA  Affiliate  has   incurred  or

                                        - 5 -





               reasonably expects  to incur any Withdrawal  Liability under
               Section 4201 of ERISA as  a result of a complete  or partial
               withdrawal from  a Multiemployer  Plan which will  result in
               Withdrawal  Liability to  the Parent  Guarantor, any  of its
               Subsidiaries or any ERISA Affiliate in an amount  that could
               reasonably be expected to have a Material Adverse Effect.

          its Subsidiaries is in breach of or default under or with respect
          to any instrument, document or agreement binding upon the  Parent
          Guarantor  or   such  Subsidiary  which  breach   or  default  is
          reasonably probable to  have a Material Adverse  Effect or result
          in the creation of a Lien on any Property of the Parent Guarantor
          or its Subsidiaries.

               (j)  Disclosure.   All written information  relating to  the

          the  Parent Guarantor or any of its Subsidiaries which would have
          a Material Adverse Effect.

               (q)  Regulatory Matters.  Except  as disclosed in the Parent
          Guarantor's Form  10-K for the  fiscal year  ending December  31,
          1993, its  Report on Form 10-Q for the fiscal quarter ending June
          30,  1994, or in its  definitive Proxy Statement  relating to the
          Restructuring filed with  the Securities and Exchange  Commission
          on August 22, 1994, the Parent Guarantor and its Subsidiaries are
          to  the best  of their  knowledge in  compliance with  all rules,
          regulations  and   other  requirements  of  the   Food  and  Drug
          Administration  ("FDA")  and  other  regulatory   authorities  of
          jurisdictions  in  which  the  Parent  Guarantor or  any  of  its
          Subsidiaries  do business  or  operate manufacturing  facilities,
          including without limitation those  relating to compliance by the
          Parent  Guarantor's  or   any  such  Subsidiary's   manufacturing
          facilities  with   "Current  Good  Manufacturing   Practices"  as
          interpreted   by  the  FDA,   except  to  the   extent  any  such
          noncompliance would  not have a Material Adverse  Effect.  Except
          as  so disclosed, neither the  FDA nor any  other such regulatory
          authority has requested (or, to the Parent Guarantor's knowledge,
          are  considering  requesting)   any  product  recalls  or   other
          enforcement actions.

               (r)  Title  and Liens. Each of  the Parent Guarantor and its
          Subsidiaries has good and marketable title to its real properties
          and owns or  leases all  its other material  Properties, in  each
          case,  as shown on its  most recent quarterly  balance sheet, and
          none  of  such  Properties is  subject  to  any  Lien except  for
          Permitted Liens.

               (s)  Compliance with Law.  Each of the Parent  Guarantor and
          its  Subsidiaries  is  in  compliance with  all  Applicable  Law,
          including,  without  limitation, all  Environmental  Laws, except

                                        - 7 -





          where any failure  to comply with any such  laws would not, alone
          or  in the  aggregate,  have a  Material  Adverse Effect  on  the
          business or financial  condition of the Parent  Guarantor and its
          Subsidiaries taken as a whole, or  the Parent Guarantor's ability
          to perform its obligations under the Loan Documents.

               (t)  Trademarks, Copyrights, Etc.  The Parent  Guarantor and
          each of  its Subsidiaries  own or  have the  rights  to use  such
          trademarks, service  marks, trade names,  copyrights, licenses or
          rights in any  thereof, as in the  aggregate are adequate in  the
          reasonable judgment  of the Parent  Guarantor for the  conduct of
          the  business of the Parent Guarantor and its Subsidiaries as now
          conducted.

               SECTION 6.   Affirmative Covenants.   As long as any  of the
          Guaranteed Obligations or any  other amounts shall remain unpaid,
          or any Bank shall have any Commitment under the Credit Agreement,
          unless  otherwise agreed by  the written consent  of the Majority
          Banks:

               (a)  Compliance with Laws, Etc.   The Parent Guarantor shall
          comply,  and cause  each of  its Subsidiaries  to comply,  in all
          material   respects  with   all   Applicable  Law   except   such
          non-compliance as  would not  have a Material  Adverse Effect  or
          result in a Material Credit Agreement Change.

               (b)  Payment  of Taxes, Etc.   The Parent  Guarantor and any
          consolidated, combined or unitary group which includes the Parent
          Guarantor or any of its Subsidiaries shall pay and discharge, and
          cause  each  Subsidiary  of  the  Parent  Guarantor  to  pay  and
          discharge, before  the same  shall become delinquent,  all lawful
          claims, Taxes,  assessments and  governmental  charges or  levies
          except  where contested in good faith, by proper proceedings, and
          where  adequate reserves  therefor have  been established  on the
          books of  the Parent Guarantor  or such Subsidiary  in accordance
          with GAAP.

               (c)  Maintenance of  Insurance.  The Parent  Guarantor shall
          maintain,  and  cause  each  of  its  Subsidiaries  to  maintain,
          insurance with responsible  and reputable insurance companies  or
          associations in  such  amounts  and  covering such  risks  as  is
          usually carried  by companies  engaged in similar  businesses and
          owning  similar properties in the same general areas in which the
          Parent  Guarantor  or  such  Subsidiary  operates.    The  Parent
          Guarantor  will furnish  to  the Agent  from  time to  time  such
          information as may be requested as to such insurance.

               (d)  Preservation of Corporate Existence,  Etc.  The  Parent
          Guarantor  shall  preserve and  maintain, and  cause each  of its
          Subsidiaries to preserve and maintain, their respective corporate
          existences; provided, that  this Section 6(d) shall not  apply at
          any  time with respect to the corporate existence of a Subsidiary

                                        - 8 -





          of  the  Parent  Guarantor  (other  than  the  Borrower  and  the
          Scandinavian Principal  Companies) in  any case where  the Parent
          Guarantor's Board of Directors determines in good faith that such
          termination of corporate  existence is in  the best interests  of
          the  Parent Guarantor and its  Subsidiaries taken as  a whole and
          where  noncompliance will not have a Materially Adverse Effect on
          the Parent Guarantor  and its Subsidiaries  or any Loan  Document
          (other than a  Loan Document  delivered by a  Subsidiary that  at
          such time is no  longer a Principal Subsidiary, as  determined at
          such  time); provided,  further that this  Section 6(d)  shall be
          without prejudice  to the other  provisions of this  Guaranty and
          the Credit Agreement. 

               (e)  Books  and Access.    The Parent  Guarantor shall,  and
          shall cause each  of its  Subsidiaries to, keep  proper books  of
          record and accounts  in conformity with GAAP, and upon reasonable
          notice and  at such  reasonable times  during the  usual business
          hours   as  often   as  may   be  reasonably   requested,  permit
          representatives of the  Agent, at  its own initiative  or at  the
          request  of any Bank, to  make inspections of  its Properties, to
          examine  its books,  accounts  and records  and  make copies  and
          memoranda thereof and  to discuss its  affairs and finances  with
          its officers or directors and independent public accountants.

               (f)  Maintenance of Properties,  Etc.  The  Parent Guarantor

          which  are used or useful in the  conduct of its business in good
          working  order and condition and, from time to time make or cause
          to be  made all  appropriate repairs, renewals  and replacements,
          except  where the  failure to  do so  would not  have a  Material
          Adverse Effect.

               (g)  Financial  Statements.    The  Parent  Guarantor  shall
          furnish,  or cause to be furnished, to the Agent (with sufficient

               cash flows of the Parent Guarantor and  its Subsidiaries for

                    Liabilities and Costs, provided,  that, in the event of

               information   relating  to  any   proposed  change   in  the
               accounting treatment  or reporting  practices of  the Parent
               Guarantor and its Subsidiaries the nature or  scope of which
               materially affects  the calculation of any  component of any
               financial covenant,  standard  or  term  contained  in  this
               Guaranty; and

                    (ix)  prior to  the  Parent Guarantor,  or  any of  its
               Subsidiaries, (i)  entering into  any agreement  relating to
               the  sale of, or the granting of  a Lien on, assets having a
               fair market value of $10,000,000  or more, or (ii) incurring
               Indebtedness  pursuant to a single transaction the aggregate
               principal amount of which is $10,000,000 or more, the Parent
               Guarantor  shall  give  the Agent  15  days'  notice  of its
               intention to enter into such an agreement; and 

                    (x)  from  time to  time,  such  other information  and
               materials  as the Agent (or the Banks through the Agent) may
               reasonably request.

               (i)  Additional  Credit  Support  Documents.     The  Parent
          Guarantor shall  deliver, or shall cause to  be delivered, within
          five  (5) Business Days of delivery to the Agent of a certificate
          pursuant to Section 6(g)(v) hereof,  in respect of each Principal
          Subsidiary,   disclosed  on   the  schedule   attached  to   such
          certificate (a) a Subsidiary Guaranty duly executed by  each such
          Principal Subsidiary or (b) if any such Principal Subsidiary is a
          Non-U.S.  Subsidiary, a  Pledge  Agreement duly  executed by  the
          Shareholders of  such  Non-U.S. Subsidiary;  provided, that  this
          Section (i) shall  not apply  to any Principal  Subsidiary as  to
          which  there  already  is  at  such  time  a  valid  and  binding
          Subsidiary Guaranty or Pledge Agreement (as the case may be).

               (j)  Delivery of Opinions.  Concurrently  with the execution
          and delivery of any  additional Credit Support Documents pursuant
          to  Section 6(i) hereof,  the Parent Guarantor  shall deliver, or
          shall cause to be  delivered, to the Agent an opinion  of counsel
          relating to such  additional Credit Support Document  in form and
          substance  substantially  similar  to the  opinions  rendered  in
          connection with comparable agreements on the Effective Date.

               (k)  A.L.  Labs   Transfer.    The  Parent  Guarantor  shall
          consummate   the  A.L.   Labs   Transfer  (as   defined  in   the
          Restructuring Agreement) as soon as practicable and in  any event
          within 90 days of the Effective Date.

               (l)  Stock  Exchange  Listing.     The  Parent   Guarantor's
          securities  shall at  all times be  listed on The  New York Stock
          Exchange.

               SECTION 7.    Negative Covenants.   So  long as  any of  the
          Guaranteed Obligations  or any other amounts  shall remain unpaid
          or any Bank shall have any Commitment under the Credit Agreement,
          unless otherwise  agreed by the  written consent of  the Majority
          Banks:

               (a)  Liens, Etc.   The Parent Guarantor  shall not, directly
          or indirectly, create or  suffer to exist,  or permit any of  its
          Subsidiaries to  create or suffer to exist, any Lien upon or with
          respect  to any of its Properties, whether now owned or hereafter
          acquired, or assign, or permit any of its Subsidiaries to assign,
          any  right to receive  income, in each case  to secure or provide
          for  the  payment  of  any Indebtedness  of  any  Person,  except
          Permitted Liens.

               (b)  Mergers.    The Parent  Guarantor  shall  not merge  or
          consolidate in any transaction in which it or the Borrower is not
          the  surviving  Person.   The Parent  Guarantor shall  not permit
          without the consent of the Majority Banks any of its Subsidiaries
          to  merge  or  consolidate  in  any  transaction  in  which  such
          Subsidiary is not the  surviving Person other than in  mergers of
          any  Subsidiary  (other  than   the  Borrower)  into  the  Parent
          Guarantor, the Borrower or any  other wholly owned Subsidiary  of
          the  Parent Guarantor or the Borrower that is incorporated in the
          U.S.;  provided, that  with  respect  to  mergers  in  which  the
          surviving entity  is not  the Parent  Guarantor or  the Borrower,
          then the Parent  Guarantor shall cause  such surviving entity  to
          deliver a Subsidiary Guaranty if immediately after the merger the
          surviving entity is a Principal Subsidiary (as determined at such
          time) in  respect of which there  is not, at such  time, a valid,
          legal  and  binding  Subsidiary  Guaranty  or  Pledge  Agreement;
          provided, further, that the  Majority Banks will not unreasonably
          withhold their consent to  a merger or other combination  of A.L.
          Pharma AS and New A.L.-Oslo.
           
               (c)  Substantial  Asset  Sale.   The Parent  Guarantor shall
          not,  and  shall not  permit any  of  its Subsidiaries  to, sell,
          lease,  transfer or otherwise  dispose of all  or any substantial
          part of its or  their assets  (including any of  the stock of the
          Scandinavian  Principal Companies  owned by  it or  them), except
          that  this Section  7(c) shall  not apply  to any  disposition of
          assets  (i)  in  the ordinary  course  of  business  or (ii)  any
          disposition of  assets (other than assets consisting of the stock
          of the  Scandinavian Principal Companies  or assets owned  by the
          Scandinavian  Principal Companies) (A)  to the  Parent Guarantor,
          the Borrower  or any Principal  Subsidiary (in  respect of  which
          there is  in  existence a  legal,  valid and  binding  Subsidiary
          Guaranty or Pledge Agreement)  or (B) where the proceeds  of such

                                        - 14 -





          disposition (I) consist  solely of cash  or cash equivalents  and
          (II)  the Net Cash Proceeds of such disposition are first applied
          towards  the   prepayment  of  any  Loans   then  outstanding  in
          accordance with Section 5.4(a) of the Credit Agreement; provided,
          that for purposes of this Section 7(c), any such prepayment shall
          be  effected  on the  next succeeding  day  on which  an interest
          payment  is  due  in respect  of  the  Loan  being prepaid  after
          consummation of the  asset sale, and if such day  is not the last
          day of  the Interest Period in respect of the Loan or Loans being
          prepaid, the Borrower shall  continue to be liable for  any costs
          or expenses pursuant to Section 12.4(c) of the Credit Agreement.

               (d)  Transactions  with  Affiliates.   The  Parent Guarantor
          shall not engage in,  and will not permit any of its Subsidiaries
          to engage in,  any transaction  with an Affiliate  of the  Parent
          Guarantor or of  such Subsidiary other  than transactions in  the
          ordinary course of  business between a Subsidiary  and its parent
          or among Subsidiaries of  the Parent Guarantor that are  on terms
          no less favorable  to the Parent  Guarantor or such  Subsidiaries
          than as would be obtained in a comparable arms-length transaction
          and  other than  transactions  contemplated by,  and effected  in
          accordance with, the Restructuring.

               (e)  Activities.   Following consummation  of the  A.L. Labs
          Transfer,  the Parent Guarantor shall  not engage in any business
          activities,  own  any  Properties  or incur  any  obligations  or
          Indebtedness other than (a) as contemplated by the Loan Documents
          and the Restructuring Agreement, and (b) the ownership of  Equity
          of  its Subsidiaries  and  of the  real  estate and  improvements
          thereon  relating  to  its  manufacturing  facility  in   Chicago
          Heights, Illinois.

               (f)  Restrictions on Indebtedness.  (i) The Parent Guarantor
          shall  not incur, and shall not permit its Subsidiaries to incur,
          Indebtedness  except Permitted  Indebtedness  (subject to  clause
          (ii)  below);   provided,  that   prior  to  the   incurrence  of
          Subordinated  Indebtedness,  the  Agent  shall  have  received an
          opinion of counsel relating to such Subordinated Indebtedness and
          stating that in the  opinion of such counsel the  Indebtedness of
          the Loan Parties under the Loan  Documents is senior indebtedness
          within the meaning  of such term (or a term analogous thereto) as
          used  in the terms  and provisions relating  to such Subordinated
          Indebtedness.

               (ii)   Notwithstanding  clause   (i)  above,   no  Permitted
          Indebtedness may be incurred unless (A) with respect to Permitted
          Indebtedness  described  in  clauses   (3)  through  (6)  of  the
          definition  of Permitted  Indebtedness, and  except  as otherwise
          provided  in  the Loan  Documents,  the Parent  Guarantor  or the
          Borrower shall have  given the  Agent at least  7 Business  Days'
          prior notice  of  the intention  to  incur such  Indebtedness  in
          accordance  with the terms hereof and (B) if the principal amount

                                        - 15 -





          of  such Indebtedness is $1,000,000  or more, the  Person to whom
          the  debtor in respect of  such  Indebtedness  shall be obligated
          becomes  a party  to the  Intercreditor Agreement  (unless it  is
          already  a  party to  such  agreement);  provided, however,  that
          clause (B) hereof shall  not apply to (1) Subordinated  Debt, (2)
          Indebtedness that is otherwise Permitted Indebtedness and that is
          issued pursuant to  a (x) registration  statement filed with  the
          Securities  and Exchange  Commission or  (y) a  private placement
          with institutional  investors or (3)  Permitted Indebtedness that
          is secured by  Permitted Liens.   In the case  of such a  private
          placement with institutional  investors, the Parent  Guarantor or
          the Borrower shall use its reasonable best efforts to ensure that
          the  institutional  investors  in such  private  placement become
          parties to the Intercreditor Agreement.

               SECTION  8.  Financial  Covenants.   As long  as any  of the
          Guaranteed Obligations shall remain unpaid or any Bank shall have
          any Commitment  under  the  Credit  Agreement,  unless  otherwise
          agreed by the written consent of the Majority Banks:

               (a)  Minimum Equity Ratio.   The Equity Ratio  of the Parent
          Guarantor and its Subsidiaries shall not at any time be less than
          0.3:1.

               (b)  Minimum Total Capital.  The Total Capital of the Parent
          Guarantor  and  its  Subsidiaries  shall not  be  less  than  (a)
          $170,000,000, from the Agreement Date  to December 31, 1995,  (b)
          $185,000,000, from December 31, 1995 to December 31, 1996 and (b)
          $200,000,000, at any time thereafter.

               (c)  Current Ratio.  The ratio of  Current Assets to Current
          Liabilities of  the Parent  Guarantor and its  Subsidiaries shall
          not at any time be less than 1.30:1.

               (d)  Interest  Coverage Ratio.   The  ratio of  (i) Earnings
          from Operations plus interest income to (ii)  Total Cash Interest
          Expense shall not be less than (A) 1.75:1 for the period from the
          Agreement  Date through December 31,  1995 and (B)  1.85:1 at all
          times thereafter;  provided, however,  that for purposes  of this
          Section 8(d),  the calculation of "Earnings  from Operations" for
          any period  during  1994  shall  not include  any  income  effect
          attributable  to  (x)  the  Restructuring Charge  or  (y)  Merger
          Expenses  specifically expensed  in the  fourth quarter  of 1994;
          and, provided, further, that in calculating the Interest Coverage
          Ratio for purposes of this Section 8(d), changes in Earnings from
          Operations,  interest  income  or  Total  Cash  Interest  Expense
          attributable to foreign exchange  fluctuations shall not be taken
          into account.

               (e)  Minimum  Net  Worth.    The  Net  Worth  of the  Parent
          Guarantor and its Subsidiaries shall not at any time be less than
          $170,000,000.  

                                        - 16 -





               SECTION  9.   Payments and  Computations.   (a)   The Parent
          Guarantor  shall make  each payment  payable by it  hereunder not
          later than 11:00 A.M. (New  York City time) on the day  when due,
          in Dollars,  to the Agent at  its address referred to  in Section
          12.2  of  the Credit  Agreement  in  immediately available  funds
          without set-off or  counterclaim, for the account of  the several
          Banks.

               (b)  No  Reductions.   (i) Subject  to Section  9(b)(ii) and
          (iii), payments  due to the Agent, the  Arranger, the Co-Arranger
          or any Bank hereunder, and all other terms, conditions, covenants
          and  agreements  to  be  observed and  performed  by  the  Parent
          Guarantor hereunder, shall be made, observed  or performed by the
          Parent  Guarantor without any  reduction or deduction whatsoever,
          including any reduction or deduction for any set-off, recoupment,
          counterclaim (whether sounding in tort, contract or otherwise) or
          Tax.  

               (ii)(x) If any withholding or deduction from any payment  to
          be made by  the Parent  Guarantor hereunder is  required for  any
          Taxes  under any  applicable law,  rule or  regulation, then  the
          Parent Guarantor will

                    (A)    pay  directly to  the relevant  taxing authority
               the full amount required to be so withheld or deducted;

                    (B)    promptly  forward  to  the  Agent   an  official
               receipt or  other  documentation satisfactory  to the  Agent
               evidencing such payment to such authority; and

                    (C)    pay to the  Agent for the  account of the  Banks
               such additional  amount or amounts necessary  to ensure that
               the net amount actually received by each Bank will equal the
               full amount  such  Bank  would have  received  had  no  such
               withholding or deduction been required.

               In addition, to the extent permitted by applicable law,  the
          Parent Guarantor agrees  to pay  any present or  future stamp  or
          documentary taxes, excise or property taxes, or any other charges
          or  similar levies which arise from any payment made hereunder or
          from  the execution,  delivery or  registration of,  or otherwise
          with respect to, this Guaranty or the Notes (hereinafter referred
          to as "Other Taxes").

               Each Bank shall use its reasonable best efforts to designate
          another of its then existing offices as its Lending Office if the
          making of such designation  would, without any detrimental effect
          to such Bank (as determined by  the Bank in its sole discretion),
          avoid the need for, or reduce the amount  of, such withholding or
          deduction from any payment to be  made to such Bank by the Parent
          Guarantor hereunder required for any Taxes.


                                        - 17 -





               The Parent Guarantor will indemnify each Bank and the  Agent
          for the full amount of Taxes or Other Taxes  paid by such Bank or
          the  Agent  (as the  case may  be)  and any  liability (including
          penalties, interest  and  expenses)  arising  therefrom  or  with
          respect  thereto, whether or not  such Taxes or  Other Taxes were
          correctly  or legally  asserted.   This indemnification  shall be
          made within 30 days from the date such  Bank or the Agent (as the
          case may be) makes written demand therefor.

               If  the Parent  Guarantor fails  to pay  any Taxes  or Other
          Taxes  when due to the  appropriate taxing authority  or fails to
          remit to the Agent, for the account of the respective Banks,  the
          required  receipts or  other required  documentary  evidence, the
          Parent  Guarantor shall indemnify the Agent and the Banks for any
          incremental Taxes or Other Taxes, penalties, interest or expenses
          that may become payable  by the Agent or any Bank as  a result of
          any such failure.

               (y)  Notwithstanding  subsection (x),  the Parent  Guarantor
          shall  not be required to indemnify or pay additional amounts for
          or on account of:

               (A)  Taxes imposed on or  measured by the net income  of the
          Agent or  any Bank or franchise Taxes imposed on the Agent or any
          Bank, but  in  each  case  only  to the  extent  imposed  by  the
          jurisdiction under  the laws of which  the Agent or such  Bank is
          organized  or doing  business  (other than  as  a result  of  the
          transactions contemplated by the Loan Documents or the Agent's or
          any  Bank's enforcement of its rights under any Loan Document) or
          any political subdivision or taxing authority thereof or therein,
          or by any jurisdiction in which  the Agent or such Bank's lending
          office or principal executive office is located or  any political
          subdivision or  taxing authority  thereof or therein  (except, in
          each case, to the  extent required by the following  paragraph to
          make payments on a net after-tax-basis), or

               (B)  any  Tax or Other Tax  imposed by reason  of either (i)
          the failure  of  the certification  made by  a Bank  on any  form
          provided pursuant to Section 9(b)(iii) to be accurate and true in
          all  material respects  unless any  such failure  is attributable
          solely to a Change in Tax Law that occurs on or after the date on
          which such  form is provided by such Bank, or (ii) the failure by
          a Bank to deliver  to the Parent Guarantor (or the  Borrower) and
          the Agent two duly completed and executed copies of IRS Form 1001
          or  4224 (or successor  applicable forms) in  accordance with the
          second sentence  of Section 9(b)(iii), certifying  that such Bank
          is entitled to receive payments under this Guaranty and the Loans
          without  deduction or  withholding of  any United  States federal
          income taxes, provided that this clause (B)(ii) will not apply if
          such failure  is attributable solely to a  Change in Tax Law that
          occurs on or after the date hereof.


                                        - 18 -





               All  amounts payable  as additional  amounts or  indemnities
          pursuant to this Section  9(b) shall include an amount  necessary
          to hold the Agent or  the relevant Bank harmless on a  net after-
          tax-basis from and  against all  Taxes required to  be paid  with
          respect to  or  as a  result of  the payment  of such  additional
          amount   or  indemnity  (including,   without  limitation,  Taxes
          described in clause (A) of the preceding paragraph.)

               (iii)  Each Bank that is not a United States person (as such

          "fraudulent conveyance", or otherwise, all as though such payment
          or performance had not been made.  In the event that any payment,
          or  any  part  thereof,   is  rescinded,  reduced,  restored,  or
          returned, the Guaranteed Obligations shall, to the fullest extent
          permitted by law, be  reinstated and deemed reduced only  by such
