           (c) Revolving  Facility.  Loans under the  Revolving  Facility
     (each a "Revolving Loan" and, collectively, the "Revolving Loans"): (i)
     may be incurred by the Borrower or any Foreign Subsidiary Borrower at
     any time and from time to time on and after the Closing Date and prior
     to the date the Total Revolving Commitment terminates; (ii) except as
     otherwise provided, may, at the option of the Borrower or any
     applicable Foreign Subsidiary Borrower, be incurred and maintained as,
     or Converted into, Revolving Loans which are Prime Rate Loans, or
     Eurodollar Loans denominated in Dollars or in an Alternative Currency,
     provided that all Revolving Loans made as part of the same Revolving
     Borrowing shall, unless otherwise specifically provided herein, consist
     of Revolving Loans of the same Type and currency; (iii) when incurred
     by the Borrower may, subject to the provisions hereof, be denominated
     in U. S. Dollars or in an Alternative Currency; (iv) when incurred by a
     Foreign Subsidiary Borrower may be denominated only in an Alternative
     Currency; (v) may only be incurred if after giving effect thereto the
     aggregate principal amount of the outstanding Revolving Loans which are
     not denominated in Dollars represents less than 50% of the then Total
     Revolving Commitment; (vi) may only be incurred if after giving effect
     thereto the aggregate principal amount of the outstanding Revolving
     Loans of all Foreign Subsidiary Borrowers represents less than 25% of
     the then Total Revolving Commitment; (vii) may be repaid or prepaid and
     reborrowed in accordance with the provisions hereof; (viii) may only be
     made if after giving effect thereto the Unutilized Total Revolving
     Commitment exceeds the outstanding Swing Line Loans; and (ix) shall not
     exceed for any Lender at any time outstanding that aggregate principal
     amount which, when added to the product at such time of (A) such
     Lender's Revolving Facility Percentage, times (B) the aggregate Letter
     of Credit Outstandings, equals the Revolving Commitment of such Lender
     at such time. In addition, no Revolving Loans shall be incurred at any
     time if after giving effect thereto the Borrower would be required to
     prepay Revolving Loans in accordance with section 5.2(b).

           (d) Swing Line Facility; Possible Participations in Swing Line
     Loans.  Loans to the  Borrower under the Swing Line Facility (each a
     "Swing Line Loan" and, collectively,  the "Swing Line Loans") (i) shall
     be made only by the Swing Line Lender, (ii) may be made at any time and
     from time to time on and after the  Closing Date and prior to the date the
     Swing Line Commitment terminates; (iii) shall be made only in U.S. Dollars;
     (iv) shall have a maturity of one Business  Day; (v) may only be incurred
     as a Money Market Rate Loan; (iv) shall be incurred in the minimum amount
     of $500,000, or any multiple of $100,000 in excess thereof;  (vi) may be
     repaid or prepaid and reborrowed in accordance with the provisions hereof;
     (vii) may only be made if after giving effect thereto the Unutilized Total
     Revolving Commitment exceeds the outstanding Swing Line Loans; and (viii)
     shall not exceed for the Swing Line Lender at any time outstanding its
     Swing Line Revolving Commitment in effect at such time. In addition, no
     Swing Line Loan may be incurred at any time if at such time, and in lieu of
     incurring such Swing Line Loan, the Borrower would not have been  entitled
     to make a Revolving Borrowing consisting of Prime Rate Loans in the same
     aggregate principal amount,ignoring for such purpose the differences in the
     Minimum Borrowing Amount between Swing Line Loans and Revolving Loans.

           The Swing  Line  Lender  may by  written  notice  given to the
     Administrative Agent not later than 10:00 A. M. (local time at the Notice
     Office), on any Business Day require the Revolving Lenders to acquire
     participations on such Business Day in all or a portion of the Swing Line
     Loans outstanding. Such notice shall specify the aggregate amount of Swing
     Line Loans in which Revolving Lenders will participate.  Promptly upon
     receipt of such notice, the Administrative Agent will give notice thereof
     to each Revolving Lender, specifying in such notice such Lender's Revolving
     Facility  Percentage of such Swing Line Loan or Loans.  Each Revolving
     Lender hereby absolutely and unconditionally agrees, upon receipt of notice


                                       4


     as provided  above,  to pay to the Administrative Agent, for the account of
     the Swing Line Lender, such Lender's Revolving Facility Percentage of such
     Swing  Line Loan or Loans.  Each Revolving Lender acknowledges and agrees
     that its obligation to acquire participations in Swing Line Loans pursuant
     to this paragraph is absolute and unconditional and shall not be affected
     by any circumstance whatsoever, including the occurrence and continuance
     of a Default or Event of Default or any reduction or termination of the
     Commitments, and that each such payment shall be made without any offset,
     abatement, withholding or reduction whatsoever.  Each Revolving Lender
     shall comply with its obligation under this paragraph by wire transfer of
     immediately available funds, in the same manner as provided in section 2.4
     with respect to Revolving Loans  made by such  Lender (and  section  2.4
     shall apply, mutatis mutandis, to the payment obligations of the Revolving
     Lenders), and the administrative  Agent shall  promptly  pay to the Swing
     Line Lender the amounts so received  by it from  the  Revolving  Lenders.
     The Administrative Agent shall notify the Borrower of any participations in
     any Swing Line Loan acquired pursuant to this paragraph, and thereafter
     payments in respect of such Swing Line Loan shall be made to the
     Administrative Agent and not to the Swing Line Lender.  Any amounts
     received by the Swing Line Lender from the Borrower (or other party on
     behalf of the  Borrower) in respect of a Swing Line Loan after  receipt by
     the Swing Line Lender of the proceeds of a sale of participations therein
     shall be promptly remitted to the Administrative Agent;  any such amounts
     received by the Administrative Agent shall be promptly remitted by the
     Administrative Agent to the Revolving Lenders that shall have made their
     payments  pursuant to this paragraph and to the Swing Line  Lender,  as
     their interests may appear.  The  purchase of participations in a Swing
     Line Loan pursuant to this  paragraph  shall not  relieve  the  Borrower of
     any  default  in the  payment thereof.  Notwithstanding  the foregoing,  a
     Revolving  Lender shall not have any obligation to acquire a participation
     in a Swing Line Loan pursuant to this  paragraph  if an Event of  Default
     shall  have  occurred  and be continuing at the time such  Swing  Line Loan
     was first made and such Revolving  Lender shall have notified the Swing
     Line Lender in writing, at least one  Business  Day prior to the time such
     Swing Line Loan was first  made,  that such Event of  Default has occurred
     and that such Lender will not acquire participations in Swing Line Loans
     made while such Event of Default is continuing.

     1.7.  Borrowing  Procedures  for  Revolving  Loans  Denominated  in  an
Alternative  Currency and for Swing Line Loans, etc.  Effective on the Effective
Date of this Amendment  provided for in section 3 hereof,  new sections  2.3(c),
(d) and (e) are added to the  Credit  Agreement,  reading in their  entirety  as
follows:

           (c) Notwithstanding the foregoing, in the case of any Notice of
     Borrowing which relates to a Revolving Borrowing consisting of Eurodollar
     Loans denominated in an Alternative Currency, such Notice of Borrowing must
     be delivered to the Administrative Agent prior to 12:00 noon (local time at
     its Notice Office), at least five Business Days' prior to the  requested
     date for the  Borrowing, and must specify the particular Alternative
     Currency requested. The Minimum Borrowing Amount for a  Borrowing  of
     Revolving  Loans  denominated  in an  Alternative Currency  shall,
     notwithstanding  anything to the  contrary contained herein, be established
     by the Administrative Agent at substantially the equivalent in the
     Alternative  Currency to the Minimum Borrowing Amount which  would  be
     applicable  to a Borrowing of Eurodollar Loans denominated in  Dollars.
     Notwithstanding  anything herein to the contrary, in the case of any Notice
     of  Borrowing  which  relates to a Revolving Borrowing consisting of
     Eurodollar Loans  denominated in an Alternative Currency, the only Interest
     Period which may be applicable to such Revolving Borrowing shall,  at the
     option of any  applicable Borrower, be a one, two or three month period.

           (d) In the case of a proposed Borrowing under the Revolving Facility
     comprised of Eurodollar Loans denominated in an Alternative Currency, the
     obligation of any Revolving Lender to make its Eurodollar Loan in the
     requested Alternative Currency as part of such Borrowing is subject to:
     subject to:

               (A) if such requested  Alternative Currency is Pounds
           Sterling,   Swedish   Krona,   German  Marks  or  euros,   the
           confirmation by the  Administrative  Agent to the Borrower not
           later than the fourth  Business Day before the requested  date
           of such  Borrowing that such  Alternative  Currency is readily
           and freely transferable and convertible into Dollars, or

               (B) if such requested  Alternative Currency is not an
           Alternative  Currency  specified  in clause  (A)  above,  such
           requested  Alternative  Currency  shall be  acceptable to such
           Lender (which  acceptability  shall be presumed if such Lender
           fails to notify the Administrative  Agent in writing not later
           than the third  Business Day before the requested date of such
           Borrowing that such Alternative  Currency is not acceptable to
           such  Lender  (any  such  notice  of   unacceptability  of  an
           Alternative  Currency  shall be  notified  immediately  by the
           Administrative Agent to the Borrower)).

                                       5


     If the Administrative Agent shall not have provided the confirmation
     referred to in clause (A) above,  or any affected Lender shall have so
     notified the  Administrative Agent that  a  particular  Alternative
     Currency is not acceptable to it as provided in clause (B) above,  the
     Administrative  Agent shall promptly  notify  the  Borrower  and each
     affected Lender thereof, whereupon the Notice of Borrowing  relating
     thereto shall be considered  withdrawn and the Borrowing  requested in
     such Notice of Borrowing shall not occur.

           (e) Notwithstanding the foregoing, in the case of any Notice of
     Borrowing which relates to a Borrowing of a Swing Line Loan from the
     Swing Line Lender,  such Notice of  Borrowing  must be delivered to the
     Administrative Agent and the Swing Line Lender no later than 1:00 P. M.
     (local time at the Notice Office) on the  requested  date  for the
     Borrowing,  and  must  specify the  amount of the Swing  Line  Loan
     requested.  Each Swing  Line Loan shall mature and be paid on the next
     Business Day,  subject to any  reborrowing thereof as a new Swing Line
     Loan.

     1.8.  Certain New or Amended  Exhibits.  Effective on the Effective Date
of this  Amendment  provided  for in section 3 hereof,  (i)  Exhibit  A-3 to the
Credit  Agreement  is  replaced by Exhibit A-3  hereto,  and (ii)  Exhibit  A-4,
Exhibit G and  Exhibit  H, each of which is  attached  hereto,  are added to the
Credit Agreement as new Exhibits A-4, G and H, respectively.

     1.9.  Forms of Notes.  Effective on the Effective Date of this Amendment
provided for in section 3 hereof,  section 2.5(a) of the Credit Agreement is
amended by adding the following at the end thereof:

     The Borrower's obligation to pay the principal of, and interest on, the

     by a  promissory  note of the  Borrower substantially  in the  form of
     Exhibit A-4 with blanks appropriately completed in conformity herewith
     (the "Swing Line Note"). A Foreign Subsidiary  Borrower's obligation to
     pay the principal of, and interest on, the Revolving  Loans made to it by
     a Lender shall be  evidenced  by a Revolving  Note of such  Foreign
     Subsidiary Borrower, modified as appropriate to reflect the Alternative
     Currency or Alternative Currencies involved and with blanks appropriately
     completed in conformity herewith.

     1.10. Swing Line Note.  Effective on the Effective Date of this Amendment
provided for in section 3 hereof,  section 2.5(d) of the Credit Agreement is
amended by adding the following at the end thereof:

     The Swing Line Note issued by the Borrower to the Swing Line Lender shall:
     (i) be executed by the Borrower; (ii) be payable to the order of such
     Lender and be dated on or prior to the date the first loan evidenced

     The obligations of the Lenders to make any Revolving Loan on the occasion
     of the first Borrowing by any Foreign Subsidiary Borrower hereunder is
     subject to the satisfaction of the following conditions:

                 (a) Notes.  Receipt by the  Administrative  Agent for the
           account of each applicable Lender of each appropriate Note or Notes
           executed by such Foreign Subsidiary Borrower, in each case, in the
           amount,  maturity and as otherwise provided herein.


                 (b) Certified Resolutions and Incumbency.  Receipt by the
           Administrative Agent, in sufficient quantities for the Revolving
           Lenders, of certified resolutions and an incumbency certificate for
           such Foreign Subsidiary Borrower, satisfactory in form and substance
           to the Administrative Agent.

                 (c) Election  to  Participate.   Receipt by the Administrative
           Agent,  in  sufficient   quantities  for  the Revolving Lendgers, of
           a duly executed Election to Participate of such Foreign Subsidiary
           Borrower,  satisfactory in form and substance to the Administrative
           Agent, and acceptance of such Election to  Participate  by the
           Administrative Agent (which acceptance shall be effected by the
           Administrative Agent only pursuant to the instructions, or with the
           consent, of the Required Revolving Lenders).

     1.17. Addition and Deletion of Foreign  Subsidiary  Borrowers.  Effective
on the Effective Date of this Amendment provided for in section 3 hereof, a new
section 8.16 is added to the Credit Agreement, reading in its entirety as
follows:

           8.16. Addition and Deletion of Foreign Subsidiary Borrowers.
     Whenever the Borrower determines that it desires for a  Foreign
     Subsidiary which is not already a Foreign Subsidiary Borrower to become
     a party hereto as a Foreign Subsidiary Borrower,  it will cause such
     Foreign Subsidiary to deliver to the Administrative  Agent an Election
     to  Participate  for such Foreign Subsidiary and the other  documents
     contemplated  by section  6.3.  No Election to Participate  shall be
     effective  to add a Foreign  Subsidiary  Borrower hereunder or for any
     other  purposes of this Agreement unless it is accepted in writing by
     the Administrative Agent as evidenced by the  signature of one of its
     officers in the space provided at the end thereof.  No acceptance of an
     Election to Participate shall be effected by the Administrative  Agent
     except pursuant to the instructions,  or with the consent,  of the
     Required Revolving Lenders. If at any time the Borrower determines that
     a Foreign Subsidiary should no longer be a Foreign Subsidiary Borrower,
     it may, if such Foreign Subsidiary Borrower has no outstanding Loans or
     other Obligations hereunder,  cause such Foreign Subsidiary Borrower to
     deliver to the Administrative Agent an Election to Terminate with respect
     to such Foreign Subsidiary Borrower.

           Without limitation of the provisions of section 2.9 hereof, if
     the cost to any Lender of making or maintaining any Revolving loan to a
     Foreign  Subsidiary Borrower is  increased  (or the amount of any sum
     received or receivable by any Lender (or its Applicable Lending Office)
     is  reduced) by an amount deemed in good faith by such  Lender to be
     material,  by reason of the fact that such Foreign Subsidiary  Borrower
     is incorporated in, or conducts business in, a jurisdiction outside the
     United States, such Foreign Subsidiary Borrower shall indemnify such
     Lender for such increased cost or reduction within 15 days after demand
     by such Lender (with a copy to the Administrative Agent). A certificate
     of such Lender claiming  compensation  under this paragraph and setting
     forth the additional amount or amounts to be paid to it hereunder (and
     the basis for the calculation of such amount or amounts) shall be
     conclusive in the absence of manifest error.

                                       8


     1.18. Judgment  Currency.  Effective  on the  Effective  Date of this
Amendment  provided  for in section 3 hereof,  a new section 12.22 is added to
the Credit Agreement, reading in its entirety as follows:

           12.22. Judgment Currency. (a) If for the purposes of obtaining
     judgment in any court it is necessary to convert a sum due hereunder or
     under any of the Notes in any currency (the "Original  Currency") into
     another currency (the "Other  Currency") the parties hereto agree, to the
     fullest extent that they may effectively do so, that the rate of exchange
     used shall be that at which in accordance with normal banking procedures
     the Administrative Agent could  purchase  the  Original Currency with the
     Other Currency at the Payment Office on the second Business Day preceding
     that on which final judgment is given.

           (b)    The  obligation  of the Borrower or any other Credit Party in
     respect  of any sum  due in the Original Currency from it to any Lender or
     the Administrative Agent hereunder shall, notwithstanding any judgment in
     any Other Currency, be discharged only to the extent that on the Business
     Day following receipt by such Lender or the Administrative Agent (as the
     case may be) of any sum adjudged to be so due in such Other Currency such
     Lender or the Administrative Agent (as the case  may be) may in accordance
     with  normal banking procedures purchase U.S. Dollars with such Other
     Currency; if the amount of the Original Currency so purchased is less than
     the sum originally due to such Lender or the Administrative Agent (as the
     case may be) in the Original Currency, the Borrower and/or any other
     applicable Credit Party agrees, as a separate obligation and
     notwithstanding any such judgment, to indemnify such Lender or the
     Administrative Agent (as the case may be) against such loss, and if the
     amount of the Original Currency so purchased exceeds the sum originally due
     to any Lender or the Administrative Agent (as the case may be) in the
     Original Currency, such Lender or the Administrative Agent (as the case may
     be) agrees to remit to the applicable Borrower or other Credit Party such
     excess.

     1.19. Parent  Guaranty.  Effective on the Effective Date of this Amendment
provided for in section 3 hereof, a new section 13 is added to the Credit
Agreement, reading in its entirety as follows:

           SECTION 13        GUARANTY BY THE COMPANY.

           13.1. Guaranty of Other Credit Party Obligations.  STONERIDGE,
     INC., an Ohio corporation (herein in this section 13, together with its
     successors  and assign,  referred  to  as  the   "Company"),   hereby
     unconditionally guarantees, for the benefit of the Administrative Agent
     and the Lenders, the full and punctual  payment by each other Credit
     Party of the  principal  of and interest  on its Loans  and all other
     Obligations, now or hereafter incurred, existing or arising pursuant to
     this Agreement or any of the other Credit Documents, including any such
     interest or other amounts  incurred or arising  during the pendency of
     any  bankruptcy,  insolvency, reorganization, receivership or similar
     proceeding,  regardless  of  whether allowed  or  allowable  in  such
     proceeding or subject to an automatic  stay under section 362(a) of the
     Bankruptcy Code (collectively, the "Guaranteed Affiliate Obligations").
     Upon failure by any other Credit Party to pay punctually any Guaranteed
     Affiliate  Obligation, the Company shall forthwith  on demand by the
     Administrative Agent pay the amount not so paid at the place and in the
     currency and otherwise in the manner specified in this Agreement or any
     other applicable agreement or instrument.

           13.2. Additional  Undertaking.  As a separate,  additional and
     continuing  obligation,  the Company unconditionally and irrevocably
     undertakes and agrees, for the benefit of the Administrative Agent and
     the Lenders  that,  should any amounts not be recoverable from the
     Company under  section  13.1  for any reason whatsoever (including,
     without limitation,  by reason of any provision of any Credit Document
     or any other agreement or instrument executed in connection  therewith
     being or becoming void,  unenforceable,  or otherwise invalid under any
     applicable law) then,  notwithstanding any notice or knowledge thereof
     by any  Lender,  the  Administrative  Agent,  any of their  respective
     Affiliates,  or any other person, at any time,  the Company as sole,
     original and independent obligor, upon demand by the Administrative
     Agent, will make payment to the  Administrative  Agent, for the account
     of the Lenders and the Administrative Agent, of all such obligations
     not so  recoverable by way of full indemnity,  in such currency and
     otherwise in such manner as is provided in the Credit Documents or any
     other applicable agreement or instrument.

                                       9


           13.3.  Guaranty  Unconditional,  etc. The obligations  of the
     Company under this section 13 shall be unconditional and absolute and,
     without limiting the generality of the foregoing shall not be released,
     discharged or otherwise affected by the occurrence, one or more times,
     of any of the following:

                  (i) any extension, renewal, settlement,  compromise,
           waiver or release  in  respect to any Guaranteed Affiliate
           Obligation  of any other Credit Party under any agreement or
           instrument, by operation of law or otherwise;

                  (ii) any  modification or amendment of or supplement to this
           Agreement, any Note, any other Credit Document, or any agreement or
           instrument evidencing or relating to any Guaranteed Affiliate
           Obligation;

                  (iii) any release,  non-perfection or invalidity of any direct
           or indirect security for any Guaranteed  Affiliate Obligation of any
           other Credit Party under any  agreement or instrument evidencing or
           relating to any Guaranteed Affiliate Obligation;

                  (iv) any change in the corporate existence, structure
           or  ownership  of any other Credit  Party or any  insolvency,
           bankruptcy, reorganization  or  other  similar   proceeding
           affecting any  other Credit  Party  or  its  assets  or  any
           resulting  release or discharge of any obligation of any other
           Credit  Party  contained in  any  agreement  or  instrument
           evidencing or relating to any Guaranteed Affiliate Obligation;

                  (v) the  existence  of any  claim,  set-off  or other rights
           which the  Company  may have at any time against  any other Credit
           Party, any Agent, any Lender, any of their Affiliates, or any other
           person, whether in connection herewith or any unrelated transactions;

                  (vi) any invalidity or unenforceability relating to or against
           any other Credit Party for any reason of any agreement or instrument
           evidencing or relating to any Guaranteed Affiliate Obligation, or any
           provision of applicable law or regulation purporting to prohibit the
           payment by any other Credit Party of any Guaranteed  Affiliate
           Obligations; or

                  (vii) any other  act or omission  to act or delay of any kind
           by any other Credit Party, any Agent, any Lender or any other person
           or any other circumstance  whatsoever  which might, but for the
           provisions of this section 13, constitute a legal or  equitable
           discharge  of the  Company's  obligations under this section 13.

           13.4.  Company  Obligations to Remain in Effect;  Restoration.
     The  Company's obligations  under this section 13 shall remain in full
     force and effect until the Commitments shall have terminated,  and the
     principal of and interest on the Notes and other  Guaranteed  Affiliate
     Obligations, and all other amounts payable by the Company or any other
     Credit  Party under the Credit  Documents  or any other  agreement  or
     instrument  evidencing or relating to any of the  Guaranteed  Affiliate
     Obligations, shall have been paid in full.  If at any time any payment
     of any of the  Guaranteed Affiliate  Obligations  of any other  Credit
     Party in respect of any Guaranteed  Affiliate  Obligations is rescinded
     or  must  be otherwise restored or  returned  upon  the  insolvency,
     bankruptcy or reorganization of such other Credit Party, the Company's
     obligations  under this section with respect to such payment  shall be
     reinstated  at such time as though  such  payment  had been due but not
     made at such time.

           13.5.  Waiver of  Acceptance,  etc.  The Company irrevocably
     waives acceptance hereof,  presentment,  demand, protest and any notice
     not provided for herein,  as well as any  requirement that at any time
     any action be taken by any person against any other Credit Party or any
     other person, or against any collateral or guaranty of any other person.

           13.6.  Subrogation.  Until the indefeasible payment in full of
     all of the  Obligations and the  termination of the Commitments of the
     Lenders  hereunder, the Company shall have no rights,  by operation of


                                       10


     law or  otherwise, upon  making any payment  under this section to be
     subrogated  to the rights of the payee  against any other Credit Party
     with respect to such payment or otherwise to be reimbursed, indemnified
     or exonerated by any other Credit Party in respect thereof.

           13.7.  Effect of Stay. In the event that  acceleration  of the
     time for payment of any amount  payable by any other Credit Party under
     any  Guaranteed Affiliate  Obligation  is  stayed  upon  insolvency,
     bankruptcy or reorganization  of such other  Credit  Party,  all such
     amounts  otherwise  subject  to  acceleration  under  the  terms of any
     applicable  agreement  or  instrument  evidencing  or  relating  to any
     Guaranteed Affiliate  Obligation  shall  nonetheless be payable by the
     Company under this section forthwith on demand by the Administrative Agent.

Borrower,  has been duly executed and delivered by a duly authorized officer of
the Borrower, and constitutes the valid and binding  agreement of the Borrower,
enforceable  against the Borrower in  accordance  with its terms,  except to the
extent that the enforceability thereof may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws generally affecting
creditors' rights and by equitable principles (regardless of whether enforcement
is sought in equity or at law).

     2.2.  Representations and Warranties. The representations and warranties
of the Credit Parties  contained in the Credit  Agreement or in the other Credit
Documents are true and correct in all material  respects on and as of the date

date, in which case such representations and warranties are hereby reaffirmed as
true and correct in all material respects as of the date when made.

     2.3.  No Event of Default.  No  condition  or event has occurred or
exists which constitutes or which, after notice or lapse of time or both, would
constitute an Event of Default.

     2.4.  Compliance.  The Borrower is in full compliance with all covenants
and agreements contained in the Credit  Agreement,  as amended hereby,  and the
other Credit Documents to which it is a party;  and without limitation  of the
foregoing,  each  Subsidiary of the Borrower  which,  as of the date hereof,  is
required  to be a  Subsidiary  Guarantor,  has as on or prior to the date hereof
become a Subsidiary Guarantor under the Subsidiary Guaranty.

     2.5.  Financial  Statements,  etc. The Borrower has  furnished  to the
Lenders and the Administrative Agent complete and correct copies of:

     equity, and cash flows for the fiscal years then ended, accompanied by the
     unqualified report thereon of the Borrower's independent accountants; and

All such  financial  statements  have been  prepared  in  accordance  with GAAP,
consistently  applied (except as stated  therein),  and fairly  present,  in all
material  respects,  the financial position of the Borrower and its consolidated
subsidiaries as of the respective dates indicated and the  consolidated  results
of their operations and cash flows for the respective periods indicated, subject
in the case of any such financial statements which are unaudited, to the absence
of  footnotes  and to normal  audit  adjustments  none of which  will  involve a
Material Adverse Effect.
