     condition of the primary obligor, (iii) to purchase property, securities or
     services  primarily  for the  purpose  of  assuring  the  owner of any such
     primary obligation of the ability of the primary obligor to make payment of

     holder of any such  primary  obligation  against  loss in  respect  thereof
     (each, a "Guaranty Obligation");  (b) with respect to any Surety Instrument

          part  thereof in an amount not less than  1,000,000,  or that is in an
          integral  multiple of $250,000  in excess  thereof)  into Loans of any
          other Type; or

               (2) elect, as of the last day of the applicable  Interest Period,
          to continue any Loans having Interest Periods expiring on such day (or
          any part thereof in an amount not less than $1,000,000,  or that is in
          an integral multiple of $250,000 in excess thereof);

     provided,  that if at any time  the  amount  of an  Offshore  Rate  Loan is
     reduced, by payment,  prepayment,  or conversion of part thereof to be less
     than $250,000],  such Offshore Rate Loan shall automatically convert into a
     Base Rate  Loan,  and on and after  such date the right of the  Company  to
     continue  such Loans as, and convert such Loans into  Offshore  Rate Loans,
     shall terminate.

          (b) The Company shall deliver a Notice of  Conversion/Continuation  to
     be  received by the Bank not later than 12:00 noon (New York time) at least
     (i) three Business Days in advance of the Conversion/Continuation  Date, if
     the Loans are to be converted into or continued as Offshore Rate Loans; and
     (ii) one Business Day in advance of the  Conversion/Continuation  Date,  if
     the Loans are to be converted into Base Rate Loans, specifying:

               (1) The proposed Conversion/Continuation Date;

               (2) The aggregate amount of Loans to be converted or continued;

               (3) The Type of Loans  resulting from the proposed  conversion or
          continuation; and


                                       12





               (4) Other than in the case of  conversions  into Base Rate Loans,
          the duration of the requested Interest Period.

          (c) If upon  the  expiration  of any  Interest  Period  applicable  to
     Offshore Rate Loans, the Company has failed to select timely a new Interest
     Period to be  applicable  to such  Offshore Rate Loans or if any Default or
     Event of Default then exists,  the Company  shall be deemed to have elected
     to convert such  Offshore  Rate Loans into Base Rate Loans  effective as of
     the expiration date of such Interest Period.

          (d) Unless the Bank  otherwise  consents,  during the  existence  of a
     Default  or Event of  Default,  the  Company  may not  elect to have a Loan
     converted into or continued as an Offshore Rate Loan.

     2.05 Voluntary  Termination  or Reduction of  Commitment.  The Company may,
upon not less than one Business  Day's prior notice to the Bank,  terminate  the
Revolving  Commitment,  or  permanently  reduce the  Revolving  Commitment  by a
minimum  amount of $1,000,000  or any multiple of $1,000,000 in excess  thereof;
unless,  after giving effect thereto and to any prepayments of Loans made on the
effective date thereof, the then-outstanding principal amount of the Loans would
exceed the amount of the Revolving  Commitment  then in effect.  Once reduced in
accordance with this Section, the Revolving Commitment may not be increased. All
accrued  commitment  fees  to,  but  not  including  the  effective  date of any
reduction  or  termination  of the  Revolving  Commitment,  shall be paid on the
effective date of such reduction or termination.

     2.06 Optional Prepayments. Subject to Section 3.04, the Company may, at any
time or from time to time,  upon not less than three Business Days'  irrevocable
notice to the Bank, ratably prepay Loans in whole or in part, in minimum amounts
of  $1,000,000  or any  multiple of $250,000 in excess  thereof.  Such notice of
prepayment  shall specify the date and amount of such prepayment and the Type(s)
of Loans to be  prepaid.  If such  notice is given by the  Company,  the Company
shall make such prepayment and the payment amount specified in such notice shall
be due and payable on the date specified therein, together with accrued interest
to each such date on the amount  prepaid  and any amounts  required  pursuant to
Section 3.04.

     2.07  Repayment.  The  Company  shall  repay  to the  Bank  in  full on the
Revolving  Termination Date the aggregate  principal amount of Loans outstanding
on such date.

     2.08 Interest.

          (a) Each Loan shall bear interest on the outstanding  principal amount
     thereof from its  Borrowing  Date at a rate per annum equal to the Offshore
     Rate or the Base Rate,  as the case may be (and  subject  to the  Company's
     right to convert to other  Types of Loans  under  Section  2.04),  plus the
     Applicable Margin.

          (b) Accrued but unpaid  interest on each Loan shall be paid in arrears
     on each Interest  Payment  Date.Interest  shall also be paid on the date of
     any  prepayment of Loans under Section 2.06 for the portion of the Loans so
     prepaid and upon payment (including prepayment) in full thereof and, during
     the existence of any Event of Default, accrued but


                                       13





     unpaid interest shall be paid on demand of the Bank.

          (c) Notwithstanding subsection (a) of this Section, while any Event of
     Default set forth in  paragraph  (a), (f) or (g) of Section  8.01exists  or
     after acceleration, the Company shall pay interest (after as well as before
     entry of judgment  thereon to the extent permitted by law) on the principal
     amount  of all  outstanding  Obligations,  at a rate  per  annum  which  is
     determined by adding 2% per annum to the  Applicable  Margin then in effect
     for such Loans; provided, however, that, on and after the expiration of any
     Interest  Period  applicable to any Offshore Rate Loan  outstanding  on the
     date of occurrence of such Event of Default or acceleration,  the principal
     amount of such Loan shall, during the continuation of such Event of Default
     or after acceleration,  bear interest at a rate per annum equal to the Base
     Rate plus 2%.

     2.09 Fees.

          (a)  Commitment  Fees.  The Company shall pay to the Bank a commitment
     fee on the average daily unused portion of the Bank's Revolving Commitment,
     computed on a quarterly  basis in arrears on the last  Business Day of each
     calendar  quarter  based  upon the daily  utilization  for that  quarter as
     calculated by the Bank,  equal to 3/8 of 1% per annum.  Such commitment fee
     shall accrue from the Closing Date to the  Revolving  Termination  Date and
     shall be due and payable  quarterly in arrears on the last  Business Day of
     each calendar quarter commencing on December 31, 1995 through the Revolving
     Termination  Date,  with  the  final  payment  to be made on the  Revolving
     Termination  Date;  provided  that,  in  connection  with any  reduction or
     termination  of  Revolving  Commitment  under  Section  2.05,  the  accrued
     commitment  fee calculated for the period ending on such date shall also be
     paid on the date of such  reduction  or  termination,  with  the  following
     quarterly  payment  being  calculated  on the basis of the period from such
     reduction  or  termination  date  to  such  quarterly   payment  date.  The
     commitment fees provided in this subsection shall accrue at all times after
     the above-mentioned  commencement date,  including at any time during which
     one or more conditions in Article IV are not met.

          (b) Other Fees.  The Company  shall pay a facility fee of $25,000,  on
     the Closing Date. In addition,  the Company shall pay an additional  fee of
     $10,000,  payable on the date of any voluntary termination of the Revolving
     Commitment by the Company prior to December 18, 1996.

     2.10 Computation of Fees and Interest.

          (a) All  computations  of  interest  for Base Rate Loans when the Base
     Rate is  determined  by the Bank's  "reference  rate"  shall be made on the
     basis of a year of 365 or 366 days,  as the case may be,  and  actual  days
     elapsed.  All other  computations of fees and interest shall be made on the
     basis of a 360-day  year and actual  days  elapsed  (which  results in more
     interest  being  paid than if  computed  on the  basis of a 365-day  year).
     Interest and fees shall accrue during each period during which  interest or
     such fees are computed from the first day thereof to the last day thereof.

          (b)  Each  determination  of an  interest  rate by the  Bank  shall be
     conclusive and binding on the Company in the absence of manifest error.


                                       14





     2.11 Payments by the Company.

          (a) All  payments  to be made by the  Company  shall  be made  without
     set-off, recoupment or counterclaim. Except as otherwise expressly provided
     herein,  all payments by the Company shall be made to the Bank at the place
     indicated as the place of payment in the signature  pages of this Agreement
     or such  other  address as the Bank may  specify in writing to the  Company
     from  time  to  time,  and  shall  be made in  dollars  and in  immediately
     available  funds,  no later  than  12:00  noon (New York  time) on the date
     specified  herein.  Any payment  received by the Bank later than 12:00 noon
     (New York  time)  shall be deemed to have been  received  on the  following
     Business Day and any applicable interest or fee shall continue to accrue.

          (b) Subject to the provisions set forth in the definition of "Interest
     Period" herein,  whenever any payment is due on a day other than a Business
     Day,  such payment  shall be made on the  following  Business Day, and such
     extension  of time shall in such case be  included  in the  computation  of
     interest or fees, as the case may be.

                                   ARTICLE III
                     TAXES, YIELD PROTECTION AND ILLEGALITY

     3.01 Taxes.

          (a) Any  and all  payments  by the  Company  to the  Bank  under  this
     Agreement and any other Loan Document  shall be made free and clear of, and
     without  deduction or withholding for, any Taxes. In addition,  the Company
     shall pay all Other Taxes.

          (b) If the Company  shall be required by law to deduct or withhold any
     Taxes,  Other Taxes, or Further Taxes from or in respect of any sum payable
     hereunder to the Bank, then:

               (1) The sum payable  shall be  increased  as  necessary  so that,
          after  making all  required  deductions  and  withholdings  (including
          deductions  and  withholdings  applicable to  additional  sums payable
          under this Section),  the Bank receives and retains an amount equal to
          the sum it would have received and retained had no such  deductions or
          withholdings been made;

               (2) The Company shall make such deductions and withholdings;

               (3) The Company shall pay the full amount deducted or withheld to
          the relevant  taxing  authority or other  authority in accordance with
          applicable law; and

               (4) The Company  shall also pay to the Bank at the time  interest
          is paid,  Further  Taxes in the  amount  that  the Bank  specifies  as
          necessary to preserve the after-tax yield the Bank would have received
          if such Taxes, Other Taxes, or Further Taxes had not been imposed.

          (c) The Company agrees to indemnify and hold harmless the Bank for the
     full


                                       15





     amount of (i)  Taxes,  (ii) Other  Taxes,  and (iii)  Further  Taxes in the
     amount that the Bank specifies as necessary to preserve the after-tax yield
     the Bank would have received if such Taxes,  Other Taxes,  or Further Taxes
     had not been  imposed and any  liability  (including  penalties,  interest,
     additions to tax and expenses)  arising  therefrom or with respect thereto,
     whether or not such Taxes,  Other Taxes, or Further Taxes were correctly or
     legally asserted.  Payment under this indemnification  shall be made within
     30 days after the date the Bank makes written demand therefor.

          (d)  Within 30 days after the date of any  payment  by the  Company of
     Taxes,  Other Taxes,  or Further Taxes,  the Company shall furnish the Bank
     the original or a certified copy of a receipt  evidencing  payment thereof,
     or other evidence of payment satisfactory to the Bank.

          (e) If the Company is required to pay any amount to the Bank  pursuant
     to  subsections  (b) or (c) of  this  Section,  then  the  Bank  shall  use
     reasonable efforts  (consistent with legal and regulatory  restrictions) to
     change the  jurisdiction  of its Lending Office so as to eliminate any such
     additional  payment by the Company  which may  thereafter  accrue,  if such
     change in the sole judgment of the Bank is not otherwise disadvantageous to
     the Bank.

     3.02 Illegality.

          (a) If the Bank determines that the introduction of any Requirement of
     Law, or any change in any Requirement of Law, or in the  interpretation  or
     administration of any Requirement of Law, has made it unlawful, or that any
     central  bank or  other  Governmental  Authority  has  asserted  that it is
     unlawful,  for the Bank or its  applicable  Lending Office to make Offshore
     Rate  Loans,  then,  on  notice  thereof  by the Bank to the  Company,  any
     obligation of the Bank to make Offshore Rate Loans shall be suspended until
     the Bank  notifies the Company that the  circumstances  giving rise to such
     determination no longer exist.

          (b) If the  Bank  determines  that  it is  unlawful  to  maintain  any
     Offshore Rate Loan, the Company  shall,  upon its receipt of notice of such
     fact and demand from the Bank,  prepay in full such  Offshore Rate Loans of
     the Bank then  outstanding,  together  with  interest  accrued  thereon and
     amounts required under Section 3.04, either on the last day of the Interest
     Period thereof, if the Bank may lawfully continue to maintain such Offshore
     Rate  Loans to such  day,  or  immediately,  if the  Bank may not  lawfully
     continue to maintain such Offshore Rate Loan. If the Company is required to
     so prepay any Offshore Rate Loan, then  concurrently  with such prepayment,
     the Company shall borrow from the Bank, in the amount of such repayment,  a
     Base Rate Loan.

     3.03 Increased Costs and Reduction of Return.

          (a) If the Bank determines that, due to either (i) the introduction of
     or any change in or in the  interpretation of any law or regulation or (ii)
     the  compliance by that Bank with any guideline or request from any central
     bank or other  Governmental  Authority  (whether or not having the force of
     law),  there  shall be any  increase in the cost to the Bank of agreeing to
     make or making,  funding or maintaining  any Offshore Rate Loans,  then the
     Company shall be liable for, and shall from time to time, upon demand,  pay
     to the Bank,  additional  amounts as are  sufficient to compensate the Bank
     for such increased costs.


                                       16





          (b) If the Bank shall have determined that (i) the introduction of any
     Capital  Adequacy  Regulation,  (ii) any  change  in any  Capital  Adequacy
     Regulation, (iii) any change in the interpretation or administration of any
     Capital  Adequacy  Regulation  by any  central  bank or other  Governmental
     Authority charged with the  interpretation or  administration  thereof,  or
     (iv)  compliance  by the Bank (or its  Lending  Office) or any  corporation
     controlling the Bank with any Capital Adequacy Regulation, affects or would
     affect the amount of capital  required or expected to be  maintained by the
     Bank or any corporation controlling the Bank and (taking into consideration
     the Bank's or such corporation's  policies with respect to capital adequacy
     and the Bank's  desired  return on capital)  determines  that the amount of
     such capital is increased as a  consequence  of its  Revolving  Commitment,
     Loans,  credits or Obligations  under this Agreement,  then, upon demand of
     the Bank to the Company,  the Company  shall pay to the Bank,  from time to
     time as specified by the Bank,  additional amounts sufficient to compensate
     the Bank for such increase.

     3.04 Funding Losses. The Company shall reimburse the Bank and hold the Bank
harmless  from any loss or  expense  which  the Bank may  sustain  or incur as a
consequence of:

          (a) The failure of the  Company to make on a timely  basis any payment
     of principal of any Offshore Rate Loan;

          (b) The failure of the  Company to borrow,  continue or convert a Loan
     after the  Company  has  given  (or is  deemed  to have  given) a Notice of
     Borrowing or a Notice of Conversion/Continuation;

          (c) The failure of the Company to make any  prepayment  in  accordance
     with any notice delivered under Section 2.06;

          (d) The  prepayment or other  payment  (including  after  acceleration
     thereof) of an Offshore  Rate Loan on a day that is not the last day of the
     relevant Interest Period; or

          (e) The automatic  conversion  under Section 2.04 of any Offshore Rate
     Loan on a day that is not the last day of the relevant Interest Period;

including any such loss or expense  arising from the liquidation or reemployment
of funds obtained by it to maintain its Offshore Rate Loans or from fees payable
to terminate the deposits from which such funds were obtained.

     3.05  Inability to Determine  Rates.  If the Bank  determines  that for any
reason  adequate and reasonable  means do not exist for determining the Offshore
Rate for any requested  Interest Period with respect to a proposed Offshore Rate
Loan, or that the Offshore Rate  applicable  pursuant to subsection  2.08(a) for
any requested Interest Period with respect to a proposed Offshore Rate Loan does
not adequately and fairly reflect the cost to the Bank of funding such Loan, the
Bank will promptly so notify the Company. Thereafter, the obligation of the Bank
to make or maintain  Offshore Rate Loans  hereunder shall be suspended until the
Bank  revokes such notice in writing.  Upon receipt of such notice,  the Company
may,  without  penalty or charge,  revoke any Notice of  Borrowing  or Notice of
Conversion/Continuation  then  submitted  by it. If the Company  does not revoke
such Notice,


                                       17





the Bank shall make,  convert or continue the Loans, as proposed by the Company,
in the amount specified in the applicable  notice submitted by the Company,  but
such Loans shall be made,  converted or continued as Base Rate Loans  instead of
Offshore Rate Loans.

     3.06  Survival.  The  agreements  and  obligations  of the  Company in this
Article III shall survive the payment of all other Obligations.

                                   ARTICLE IV

     The Company represents and warrants to the Bank that:

     5.01  Corporate   Existence  and  Power.   The  Company  and  each  of  its

     Loan Documents to which it is a party;

          (c) Is duly qualified as a foreign  corporation and is licensed and in
     good  standing  under the laws of each  jurisdiction  where its  ownership,

          (d) Is in compliance  with all  Requirements of Law;  except,  in each
     case  referred  to in clause  (c) or clause  (d),  to the  extent  that the
     failure  to do so could  not  reasonably  be  expected  to have a  Material
     Adverse Effect.

     5.02 Corporate Authorization; No Contravention. The execution, delivery and
performance by the Company and its Subsidiaries of this Agreement and each other
Loan  Document to which the Company is party,  have been duly  authorized by all
necessary corporate action, and do not and will not:

          (a)  Contravene  the  terms  of  any  of  the  Company's  Organization
     Documents;

          (b) Conflict with or result in any breach or contravention  of, or the
     creation  of any  Lien  under,  any  document  evidencing  any  Contractual
     Obligation to which the Company is a party or any order,  injunction,  writ
     or  decree  of any  Governmental  Authority  to which  the  Company  or its
     property is subject; or

          (c) Violate any Requirement of Law.

     5.03  Governmental   Authorization.   No  approval,   consent,   exemption,

Governmental   Authority  is  necessary  or  required  in  connection  with  the
execution,  delivery or performance by, or enforcement  against,  the Company or
any of its  Subsidiaries of the Agreement or any other Loan Document to which it
is a party.

     5.04 Binding  Effect.  This Agreement and each other Loan Document to which
the Company is a party  constitute the legal,  valid and binding  obligations of
the Company  enforceable against the Company in accordance with their respective
terms,  except  as  enforceability  may be  limited by


                                       20





applicable bankruptcy,  insolvency, or similar laws affecting the enforcement of
creditors'   rights   generally   or  by   equitable   principles   relating  to
enforceability.

     5.05 Litigation.  Except as specifically  disclosed in Schedule 5.05, there
are no actions, suits,  proceedings,  claims or disputes pending, or to the best

     or any  order  of  any  nature  has  been  issued  by any  court  or  other
     Governmental  Authority  purporting  to enjoin or restrain  the  execution,

     received  a  favorable  determination  letter  from the IRS and to the best
     knowledge of the Company,  nothing has occurred  which would cause the loss
     of such  qualification.  The Company and each ERISA  Affiliate has made all
     required  contributions to any Plan subject to Section 412 of the Code, and

     threatened  claims,  actions  or  lawsuits,  or action by any  Governmental
     Authority,  with respect to any Plan which has resulted or could reasonably
     be  expected  to result in a  Material  Adverse  Effect.  There has been no

     of ERISA);  (iv) neither the Company nor any ERISA  Affiliate has incurred,
     or reasonably  expects to incur,  any liability  (and no event has occurred
     which, with the giving of notice under


                                       21





     Section 4219 of ERISA,  would result in such liability)  under Section 4201
     or 4243 of ERISA with respect to a Multiemployer  Plan; and (v) neither the
     Company nor any ERISA Affiliate has engaged in a transaction  that could be

charges  levied  or  imposed  upon  them or their  properties,  income or assets
otherwise due and payable,  except those which are being contested in good faith

     transactions,  incidents or conditions, of $3,000,000 or more, and the same
     shall  remain


                                       33

     Guaranty  is for any reason  partially  (including  with  respect to future
     advances) or wholly revoked or  invalidated,  or otherwise  ceases to be in
     full force and effect, or any Guarantor or any other Person contests in any
     manner the  validity  or  enforceability  thereof or denies that it has any

to make Loans shall  automatically  terminate and the unpaid principal amount of
all  outstanding  Loans and all  interest and other  amounts as aforesaid  shall
automatically become due and payable without further act of the Bank.

this  Agreement or any other Loan  Document,  and no consent with respect to any
departure by the Company therefrom,  shall be effective unless the same shall be

consent  shall be effective  only in the specific  instance and for the specific
purpose for which given.

          (a) All  notices,  requests,  consents,  approvals,  waivers and other
     communications shall be in writing (including, unless the context expressly
     otherwise  provides,  by facsimile  transmission,  provided that any matter
     transmitted by the Company by facsimile (i) shall be immediately  confirmed
     by a telephone  call to the  recipient at the number  specified on Schedule
     9.02,  and (ii)  shall be  followed  promptly  by  delivery  of a hard copy
     original  thereof)  and  mailed,  faxed or  delivered,  to the  address  or
     facsimile number specified for notices on Schedule 9.02; or, as directed to
     the Company or the Bank,  to such other  address as shall be  designated by
     such party in a written  notice to the other party,  and as directed to any
     other party,  at such other address as shall be designated by such party in

          (c) Any  agreement  of the Bank herein to receive  certain  notices by

     notice and the Bank shall not have any  liability  to the  Company or other
     Person on account of any action  taken or not taken by the Bank in reliance
     upon such telephonic or facsimile notice.  The obligation of the Company to
     repay the Loans  shall not be  affected  in any way or to any extent by any
     failure by the Bank to receive  written  confirmation  of any telephonic or
     facsimile  notice or the receipt by the Bank of a confirmation  which is at
     variance  with the  terms  understood  by the Bank to be  contained  in the
     telephonic or facsimile notice.

     9.03 No Waiver; Cumulative Remedies. No failure to exercise and no delay in
exercising,  on the part of the Bank,  any  right,  remedy,  power or  privilege

     demand (subject to subsection  4.01(e)) for all costs and expenses incurred
     by the Bank in  connection  with the  development,  preparation,  delivery,
     administration and execution of, and any amendment,  supplement,  waiver or

     Insolvency Proceeding or appellate proceeding); and

     9.05 Company Indemnification.

          (a)  Whether  or  not  the   transactions   contemplated   hereby  are
     consummated, the Company shall indemnify, defend and hold the Bank, each of
     its Affiliates, and each of its respective officers, directors,  employees,
     counsel,  agents and  attorneys-in-fact  (each,  an  "Indemnified  Person")
     harmless  from and against any and all  liabilities,  obligations,  losses,
     damages, penalties, actions, judgments, suits, costs, charges, expenses and
     disbursements  (including  Attorney Costs) of any kind or nature whatsoever
     which may at any time  (including  at any time  following  repayment of the
     Loans) be imposed on,  incurred  by or asserted  against any such Person in
     any way  relating  to or  arising  out of this  Agreement  or any  document
     contemplated  by or referred to herein,  or the  transactions  contemplated
     hereby,  or any  action  taken or omitted  by any such  Person  under or in
     connection  with  any of  the  foregoing,  including  with  respect  to any
     investigation,   litigation  or  proceeding   (including   any   Insolvency
     Proceeding  or  appellate  proceeding)  related to or  arising  out of this
     Agreement or the Loans or the use of the proceeds  thereof,  whether or not
     any Indemnified Person is a party thereto (all the foregoing, collectively,
     the "Indemnified  Liabilities");  provided,  that the Company shall have no
     obligation  hereunder to any Indemnified Person with respect to Indemnified
     Liabilities   resulting   solely  from  the  gross  negligence  or  willful
     misconduct of such Indemnified Person. The agreements in this Section shall
     survive payment of all other Obligations.


                                       36





          (b) The  Company  shall  indemnify,  defend  and  hold  harmless  each
     Indemnified Person, from and against any and all liabilities,  obligations,
     losses,  damages,  penalties,  actions,  judgments,  suits, costs, charges,
     expenses or disbursements  (including Attorney Costs and the allocated cost
     of internal environmental audit or review services),  which may be incurred
     by or  asserted  against  such  Indemnified  Person in  connection  with or
     arising  out of any  pending or  threatened  investigation,  litigation  or
     proceeding.  No  action  taken  by  legal  counsel  chosen  by the  Bank in
     defending  against any such  investigation,  litigation  or  proceeding  or
     requested  remedial,  removal or response  action shall  vitiate or any way
     impair the Company's  obligation  and duty  hereunder to indemnify and hold
     harmless the Bank.

          (c) The obligations in this Section shall survive payment of all other
     Obligations.  At the election of any Indemnified  Person, the Company shall
     defend such  Indemnified  Person using legal counsel  satisfactory  to such
     Indemnified  Person in such Person's sole discretion,  at the sole cost and
     expense of the Company.  All amounts owing under this Section shall be paid
     within 30 days after demand.

     9.06 Marshalling; Payments Set Aside. The Bank shall be under no obligation
to marshall any assets in favor of the Company or any other Person or against or
in payment of any or all of the  Obligations.  To the  extent  that the  Company
makes a payment to the Bank,  or the Bank  exercises  its right of set-off,  and
such  payment  or  the  proceeds  of  such  set-off  or  any  part  thereof  are
subsequently invalidated,  declared to be fraudulent or preferential,  set aside
or required  (including  pursuant to any settlement  entered into by the Bank in
its  discretion)  to be repaid to a trustee,  receiver  or any other  party,  in
connection  with any Insolvency  Proceeding or otherwise,  then to the extent of
such recovery the obligation or part thereof originally intended to be satisfied
shall be revived and  continued  in full force and effect as if such payment had
not been made or such set-off had not occurred.

     9.07  Successors and Assigns.  The  provisions of this  Agreement  shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors  and assigns,  except that the Company may not assign or transfer any
of its rights or  obligations  under this  Agreement  without the prior  written
consent of the Bank.

     9.08 Assignments, Participations, etc.

          (a) The Bank may, with the written consent of the Company at all times
     other than during the existence of an Event of Default which consent of the
     Company shall not be unreasonably withheld, at any time assign and delegate
     to one or more  Persons  (provided  that no written  consent of the Company
     shall be required in connection  with any  assignment and delegation by the
     Bank to a Person that is an  Affiliate  of the Bank)  (each an  "Assignee")
     all, or any ratable part of all, of the Loans, the Revolving Commitment and
     the other rights and obligations of the Bank hereunder.

          (b) The Bank may at any time sell to one or more  commercial  banks or
     other Persons not Affiliates of the Company (a "Participant") participating
     interests in any Loans, the Revolving  Commitment of the Bank and the other
     interests  of the Bank  hereunder  and  under  the  other  Loan  Documents;
     provided,  however,  that (i) the Bank's  obligations  under this Agreement
     shall remain unchanged,  (ii) the Bank shall remain solely  responsible for
     the  performance of such  obligations,  (iii) the Company shall continue to
     deal solely and directly


                                       37





     with the Bank in connection  with the Bank's rights and  obligations  under
     this  Agreement  and the  other  Loan  Documents.  In the  case of any such
     participation, the Participant shall be entitled to the benefit of Sections
     3.01,  3.03 and 9.05 as  though  it were  also the Bank  hereunder,  and if
     amounts  outstanding under this Agreement are due and unpaid, or shall have
     been  declared or shall have become due and payable upon the  occurrence of
     an Event of Default,  each Participant shall be deemed to have the right of
     set-off in respect of its  participating  interest  in amounts  owing under
     this  Agreement  to the same  extent as if the amount of its  participating
     interest were owing directly to it as the Bank under this Agreement.

          (c) Each  Participant that is not a United States person (as such term
     is defined in Section  7701(a)(30) of the Code) for U.S. federal income tax
     purposes,  shall,  (i) prior to  becoming  a  Participant,  provide  to the
     Company  two  original  signed  copies of United  States  Internal  Revenue
     Service Form 4224 or Form 1001 certifying to such Participant's entitlement
     to a complete  exemption from United States withholding tax with respect to
     any sums payable to such Participant under this Agreement or any other Loan
     Document,  and (ii)  prior to the date any such  form  expires  or  becomes
     obsolete,  provide  to  the  Company  reasonably  sufficient  documentation
     demonstrating  that such  Participant  remains  entitled  to such  complete
     exemption  from  United  States   withholding  tax.   Notwithstanding   the
     provisions of Section 3.01 herein,  neither the Company nor any  Subsidiary
     shall  be  required  to pay  any  additional  amounts  in  respect  of this
     Agreement or any other Loan  Document to the extent that the  obligation to
     pay such amounts results from the failure of any Participant to comply with
     this paragraph (c).

     9.09  Confidentiality.  The Bank agrees to take and to cause its Affiliates
to take normal and reasonable  precautions and exercise due care to maintain the
confidentiality  of all information  identified as "confidential" or "secret" by
the Company and  provided  to it by the  Company or any  Subsidiary,  under this
Agreement or any other Loan  Document,  and neither it nor any of its Affiliates
shall use any such  information  other than in connection with or in enforcement
of this  Agreement  and the other Loan  Documents  or in  connection  with other
business  now or  hereafter  existing  or  contemplated  with the Company or any
Subsidiary;  except to the extent such information (i) was or becomes  generally
available to the public  other than as a result of  disclosure  by the Bank,  or
(ii) was or becomes  available on a  non-confidential  basis from a source other
than the Company,  provided  that such source is not bound by a  confidentiality
agreement with the Company known to the Bank; provided,  however,  that the Bank
may disclose such  information (A) at the request or pursuant to any requirement
of any Governmental Authority to which the Bank is subject or in connection with
an  examination of the Bank by any such  authority;  (B) pursuant to subpoena or
other  court  process;  (C)  when  required  to  do so in  accordance  with  the
provisions of any applicable  Requirement  of Law; (D) to the extent  reasonably
required in  connection  with any  litigation or proceeding to which the Bank or
its respective Affiliates may be party; (E) to the extent reasonably required in
connection  with the  exercise of any remedy  hereunder  or under any other Loan
Document;  (F)  to  the  Bank's  independent  auditors  and  other  professional
advisors; (G) to any Participant or Assignee, actual or potential, provided that
such Person agrees in writing to keep such information  confidential to the same
extent required of the Bank hereunder;  (H) as to the Bank or its Affiliate,  as
expressly permitted under the terms of any other document or agreement regarding
confidentiality  to which the  Company or any  Subsidiary  is party or is deemed
party with the Bank or such Affiliate; and (I) to its Affiliates.

     9.10  Set-off.  In addition to any rights and remedies of the Bank provided
by law, if an Event of



                                       38






Default exists or the Loans have been accelerated, the Bank is authorized at any
time and from time to time, without prior notice to the Company, any such notice
being waived by the Company to the fullest  extent  permitted by law, to set off
and apply any and all deposits (general or special, time or demand,  provisional
or final) at any time held by, and other  indebtedness at any time owing by, the
Bank to or for the credit or the  account  of the  Company  against  any and all
Obligations  owing to the  Bank,  now or  hereafter  existing,  irrespective  of
whether or not the Bank shall have made demand under this  Agreement or any Loan
Document and although such Obligations may be contingent or unmatured.

     9.11 Counterparts. This Agreement may be executed in any number of separate
counterparts,  each of which, when so executed, shall be deemed an original, and
all of said  counterparts  taken  together shall be deemed to constitute but one
and the same instrument.

     9.12 Severability.  The illegality or  unenforceability of any provision of
this Agreement or any instrument or agreement  required  hereunder  shall not in
any way  affect  or impair  the  legality  or  enforceability  of the  remaining
provisions of this Agreement or any instrument or agreement required hereunder.

     9.13 No Third Parties  Benefited.  This  Agreement is made and entered into
for the sole  protection and legal benefit of the Company,  the Bank, the Bank's
Affiliates,  and their  permitted  successors  and assigns,  and no other Person
shall be a direct  or  indirect  legal  beneficiary  of,  or have any  direct or
indirect cause of action or claim in connection  with,  this Agreement or any of
the other Loan Documents.

     9.14 Governing Law and Jurisdiction.

          (a) THIS  AGREEMENT  SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
     WITH, THE LAW OF THE STATE OF NEW YORK; PROVIDED THAT THE BANK SHALL RETAIN
     ALL RIGHTS ARISING UNDER FEDERAL LAW.

          (b) ANY LEGAL ACTION OR PROCEEDING  WITH RESPECT TO THIS  AGREEMENT OR
     ANY OTHER  LOAN  DOCUMENT  MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW
     YORK OR OF THE UNITED STATES FOR THE SOUTHERN  DISTRICT OF NEW YORK, AND BY
     EXECUTION AND DELIVERY OF THIS AGREEMENT,  EACH OF THE COMPANY AND THE BANK
     CONSENTS,  FOR ITSELF AND IN RESPECT OF ITS PROPERTY,  TO THE NON-EXCLUSIVE
     JURISDICTION OF THOSE COURTS.  EACH OF THE COMPANY AND THE BANK IRREVOCABLY
     WAIVES ANY  OBJECTION,  INCLUDING  ANY  OBJECTION TO THE LAYING OF VENUE OR
     BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER
     HAVE TO THE BRINGING OF ANY ACTION OR  PROCEEDING IN SUCH  JURISDICTION  IN
     RESPECT OF THIS AGREEMENT OR ANY DOCUMENT  RELATED HERETO.  THE COMPANY AND
     THE BANK EACH WAIVE  PERSONAL  SERVICE OF ANY  SUMMONS,  COMPLAINT OR OTHER
     PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY NEW YORK LAW.

     9.15  Waiver of Jury  Trial.  THE  COMPANY  AND THE BANK EACH  WAIVE  THEIR
RESPECTIVE  RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED


                                       39





UPON OR ARISING OUT OF OR RELATED TO THIS  AGREEMENT,  THE OTHER LOAN DOCUMENTS,
OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION, PROCEEDING OR
OTHER  LITIGATION  OF ANY TYPE  BROUGHT BY ANY OF THE PARTIES  AGAINST ANY OTHER
PARTY OR ANY  AFFILIATE  OF THE BANK,  PARTICIPANT  OR  ASSIGNEE,  WHETHER  WITH
RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE.  THE COMPANY AND THE BANK
EACH  AGREE  THAT ANY SUCH  CLAIM OR CAUSE OF  ACTION  SHALL BE TRIED BY A COURT
TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING,  THE PARTIES FURTHER AGREE
THAT THEIR  RESPECTIVE  RIGHT TO A TRIAL BY JURY IS WAIVED BY  OPERATION OF THIS
SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE
OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR THE
OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF. THIS WAIVER SHALL APPLY
TO ANY SUBSEQUENT  AMENDMENTS,  RENEWALS,  SUPPLEMENTS OR  MODIFICATIONS TO THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS.

     9.16  Entire  Agreement.  This  Agreement,  together  with the  other  Loan
Documents, embodies the entire agreement and understanding among the Company and
the  Bank  and   supersedes   all  prior  or   contemporaneous   agreements  and
understandings  of such  Persons,  verbal or  written,  relating  to the subject
matter hereof and thereof.

officers as of the day and year first above written.
