amount may be reduced  pursuant to Section  2.04 (such  Lender's  "Commitment").
Each  Borrowing  shall be in an aggregate  amount of  $10,000,000 or an integral
multiple of $5,000,000 in excess thereof and shall be made simultaneously by the

available  for the account of its  Domestic  Lending  Office to the Agent at the
Agent's  Account,  in same day  funds,  such  Lender's  ratable  portion of such
Borrowing.  After the Agent's receipt of such funds and upon  fulfillment of the
applicable  conditions  set forth in Article III, the Agent will make such funds
available  to the  Borrower by  depositing  the proceeds of the Advances in such
Dollar  account of the Borrower (or of such Person as the Borrower shall specify

given  simultaneously  with or prior to such Borrowing  Notice)  maintained with
such bank as the Borrower shall specify to the Agent in such Borrowing Notice.

     The parties hereto understand and agree that the Initial Lender may, in its
sole  discretion  (but shall  have no  obligation  to),  designate  a  financial
institution  or  another  Person to perform  the  Initial  Lender's  obligations
hereunder  in  accordance  with the  terms  hereof.  The  Borrower  agrees  that
performance  of any such  obligation by any such designee of the Initial  Lender
shall be deemed to constitute performance by the Initial Lender for all purposes
of this Agreement and the Note and shall  discharge the Initial Lender from such
obligation to the extent of such performance.

     (b) Any  Borrowing  Notice  delivered by the Borrower to the Agent shall be
irrevocable  and binding on the  Borrower.  The Borrower  shall  indemnify  each
Lender against any loss, cost or expense  incurred by such Lender as a result of
any failure to fulfill on or before the date specified in such Borrowing  Notice
for  such  Borrowing  the  applicable  conditions  set  forth  in  Article  111,
including, without limitation, any loss (including loss of anticipated profits),
cost or  expense  incurred  by  reason of the  liquidation  or  reemployment  of
deposits or other  funds  acquired by such Lender to fund the Advance to be made
by such Lender as part of such Borrowing when such Advance,  as a result of such
failure, is not made on such date.

     (c) The Agent shall only make  available to the Borrower on the date of any
Borrowing the ratable  portion of such Borrowing of each Lender that such Lender
has made available to the Agent on or prior to the date of such Borrowing.

     (d) The  failure of any Lender to make the Advance to be made by it as part
of any Borrowing shall not relieve any other Lender of its  obligation,  if any,
hereunder to make its Advance on the date of such Borrowing, but no Lender shall
be  responsible  for the  failure of any other  Lender to make the Advance to be
made by such other Lender on the date of any Borrowing.

to  which it  became  a  Lender  in the  case of each  other  Lender  until  the
Termination  Date at a rate per annum  equal to 1/8 of 1%,  payable  in  arrears
quarterly  on  the  last  day of  each  March,  June,  September  and  December,
commencing September 30, 1997, and on the Termination Date.

pay interest on the unpaid  principal  amount of the Advances,  if any, from the
date of the Advances until such principal amount shall be paid in full,  payable
semiannually  on each June 15th and December 15th, at an interest rate per annum
equal to the Base Rate plus 0.58%;  provided,  however,  (i) that,  prior to the
Change of Control Date and at the request of the Agent,  the  interest  rate per
annum  shall be the Base  Rate in effect  for such  Advances  plus the  Modified
Margin as determined by Agent in accordance  with  subsection (a), (b) or (c) of

Business  Days after the Change of Control  Date,  the  interest  rate per annum

amount  from the date such  amount is due until the date such  amount is paid in

rate referred to in subsection (a) of this Section 2.06 then in effect plus 2%.

to determine the Applicable Margin in accordance with subsection (a), (b) or (c)
of the definition of "Applicable Margin".

          (b) (i) If the  Lenders  and  the  Borrower  agree  to  determine  the
     Applicable Margin in accordance with subsection (a) of such definition, the
     Agent  shall  request  timely  information  from  each  Reference  Bank for
     purposes of determining  such  Applicable  Margin.  If the Borrower and the
     Lenders  agree to  determine  the  Applicable  Margin  in  accordance  with
     subsection (b) of such  definition,  the Agent shall promptly engage either
     S&P or Moody's to provide a Senior  Debt  Rating of the  Borrower as of the
     Change of Control Date.  The Agent shall provide each  Reference  Bank with
     such Senior Debt Rating and request timely  information from each Reference
     Bank for the purpose of determining such Applicable Margin.

          (ii) The Initial  Lender and the Borrower  agree to equally  share the
     expense of  engaging  S&P or Moody's to provide a Senior Debt Rating of the
     Borrower;  provided,  however,  that if either  the  Initial  Lender or the
     Borrower  shall be the sole party to decline to  determine  the  Applicable
     Margin in accordance  with  subsection (a) of the definition of "Applicable
     Margin", then such declining party shall pay the entire expense of any such
     engagement.

          (iii) If any one or more of the Reference Banks shall not furnish such
     timely  information  to the Agent for the purpose of  determining  any such
     Applicable  Margin in  accordance  with  subsection  (b)(i) of this Section
     2.07,  the Agent shall  determine  such  Applicable  Margin on the basis of
     timely information furnished by the remaining Reference Banks.

          (iv) The Agent  shall give  prompt  notice,  and in any event no later
     than 40 Business Days after the Change of Control Date, to the Borrower and
     the Lenders of the Applicable  Margin  determined by the Agent for purposes
     of Section  2.06(a)  together  with (A) the  Senior  Debt  Rating,  if any,
     established  by S&P or  Moody's,  as the case may be, and (B) the rate,  if
     any,  furnished by each Reference Bank for the purpose of determining  such
     Applicable Margin in accordance with the provisions of this Agreement.

     (c) If the  Lenders  and the  Borrower  shall  not agree to  determine  the
Applicable  Margin  in  accordance  with any of  subsections  (a) and (b) of the
definition of "Applicable  Margin",  then the  Applicable  Margin as of the date
occurring  45  Business  Days  after the  Change of  Control  Date  shall be the
percentage  per annum  determined  in  accordance  with  subsection  (c) of such
definition.

     (d) For all  purposes  hereof,  the Agent shall  determine  the  Applicable
Margin  as of 40  Business  Days  after  the  Change  of  Control  Date and such
Applicable  Margin shall be effective  from the date  occurring 45 Business Days
after the  Change of  Control  Date  until the  unpaid  principal  amount of the
Advances shall have been paid in full.

     SECTION 2.08.  Optional  Prepayments and Reductions of Commitment.  (a) The
Borrower may, upon at least three Business Days' notice to the Agent stating the
proposed date and the aggregate principal amount of the prepayment,  and if such
notice is given the Borrower shall,  prepay the outstanding  principal amount of
the Advances in whole or ratably in part,  together with (i) accrued interest to
the date of such prepayment on the principal  amount prepaid and (ii) any amount
payable pursuant to Section 8.04(c);  provided,  however, that each such partial
prepayment shall be in an aggregate principal amount of not less than $5,000,000
or an integral multiple of $1,000,000 in excess thereof.

     (b) Upon the  prepayment  in whole or in part of the Advances in accordance
with  subsection (a) of this Section 2.08, the  Commitments of the Lenders shall
be automatically reduced ratably by the amount of such prepayment.

     SECTION 2.09.  Increased Costs,  Etc. If due to either (a) the introduction
of or any change (including, without limitation, any change by way of imposition
or increase of reserve  requirements) in or in the  interpretation of any law or
regulation or (b) the compliance  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 any  Bank of  agreeing  to make or
making,  funding or maintaining an Advance, then the Borrower shall from time to
time, upon demand by such Bank (with a copy of such demand to the Agent), pay to
the Agent  for the  account  of such  Bank  additional  amounts  sufficient  (as
applicable) to compensate such Bank for such increased cost. A certificate as to
the amount of such increased cost, submitted to the Borrower by such Bank, shall
be conclusive and binding for all purposes, absent manifest error.

     SECTION  2.10.  Illegality.  Notwithstanding  any other  provision  of this
Agreement, if any Bank shall notify the Borrower that any law or regulation,  or
the  introduction  of or any  change in or in the  interpretation  of any law or
regulation,  makes  it  unlawful,  or any  central  bank or  other  Governmental
Authority asserts that it is unlawful,  for such Bank to perform its obligations
hereunder  to make an Advance or to fund or maintain an Advance  hereunder,  (a)
the  obligation  of such Bank to make,  fund and maintain  any Advance  shall be
suspended  until such Bank  shall  notify the  Borrower  that the  circumstances
causing such suspension no longer exist, (b) such Bank shall promptly notify the
Borrower of such circumstances and such suspension,  and (c) unless the Borrower
and such Bank shall have  otherwise  agreed  within  ten  Business  Days of such
notice,  the Borrower shall  forthwith on such tenth Business Day prepay in full
the Advances then outstanding together with interest accrued thereon.

     SECTION 2.11.  Payments and Computations.  (a) The Borrower shall make each
payment  hereunder  and under the Notes not later than 1:00 P.M.  (New York City
time) on the day when due in Dollars  to the Agent at the  Agent's  Account,  in
each case in immediately  available  funds.  The Agent will promptly  thereafter
cause to be  distributed  like funds  relating  to the payment of  principal  or
interest or fees ratably (other than amounts  payable  pursuant to Section 2.09,
2.12 or 8.04(c)) to the  Lenders  for the account of their  respective  Domestic
Lending  Offices,  and like funds  relating to the  payment of any other  amount
payable to any Lender to such  Lender for the  account of its  Domestic  Lending
Office,  in each  case to be  applied  in  accordance  with  the  terms  of this
Agreement.  Upon its acceptance of an Assignment and Acceptance and recording of
the information  contained  therein in the Register pursuant to Section 8.07(d),
from and after the effective date specified in such  Assignment and  Acceptance,
the Agent shall make all  payments  hereunder  and under the Notes in respect of
the interest assigned thereby to the Lender assignee thereunder, and the parties
to such Assignment and Acceptance shall make all appropriate adjustments in such
payments for periods prior to such effective date directly between themselves.

     (b) All computations of interest and of fees shall be made in good faith by
the  Agent on the  basis of a year of 360 days  for the  actual  number  of days
(including the first day but excluding the last day) occurring in the period for
which such interest or fees are payable.

     (c) Whenever any payment hereunder or under the Notes shall be stated to be
due on a day other than a Business  Day,  such payment shall be made on the next
succeeding  Business  Day,  and such  extension  of time  shall in such  case be
included in the computation of payment of interest or fee, as the case may be.

     (d) Unless the Agent shall have received  notice from the Borrower prior to
the date on which any payment is due to the Lenders  hereunder that the Borrower
will not make such  payment in full,  the Agent may assume that the Borrower has
made  such  payment  in full to the Agent on such  date and the  Agent  may,  in
reliance upon such  assumption,  cause to be  distributed to each Lender on such
due date an  amount  equal to the  amount  then due such  Lender.  If and to the
extent the  Borrower  shall not have so made such  payment in full to the Agent,
each Lender shall repay to the Agent forthwith on demand such amount distributed
to such Lender together with interest  thereon,  for each day from the date such
amount is  distributed  to such Lender  until the date such  Lender  repays such
amount to the Agent, at the Federal Funds Rate.

     SECTION 2.12. Taxes. (a) Any and all payments by the Borrower  hereunder or
under the Notes shall be made, in accordance  with Section 2.11,  free and clear
of and  without  deduction  for any and all  present  or future  taxes,  levies,
imposts, deductions,  charges or withholdings,  and all liabilities with respect
thereto,  excluding,  in the case of each Lender and the Agent, net income taxes
that are imposed by the United States and net income taxes (or  franchise  taxes
imposed in lieu  thereof)  that are  imposed on such  Lender or the Agent by the
state or foreign  jurisdiction  under the laws of which such Lender or the Agent
(as the case may be) is organized or any political  subdivision  thereof and, in
the case of each Lender,  net income taxes (or  franchise  taxes imposed in lieu
thereof) that are imposed on such Lender by the state or foreign jurisdiction of
such Lender's Domestic Lending Office or any political  subdivision thereof (all
such nonexcluded taxes, levies, imposts, deductions,  charges,  withholdings and
liabilities  in  respect  of  payments   hereunder  or  under  the  Notes  being
hereinafter referred to as "Taxes"). If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum  payable  hereunder  or under any
Note, (i) the sum payable shall be increased as may be necessary so that,  after
making all required deductions  (including  deductions  applicable to additional
sums payable  under this  Section  2.12),  such Lender or the Agent  receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower  shall make such  deductions  and (iii) the Borrower shall pay
the full amount deducted to the relevant  taxation  authority or other authority
in accordance with applicable law.

     (b) In  addition,  the  Borrower  shall pay any  present  or future  stamp,
documentary,  excise, property or other taxes, charges or levies that arise from
any payment made hereunder or under the Notes or from the execution, delivery or
registration  of, or  otherwise  with  respect to, this  Agreement  or the Notes
(hereinafter referred to as "Other Taxes").

     (c) The  Borrower  shall  indemnify  each Lender and the Agent for the full
amount of Taxes or Other  Taxes and for the full  amount of Taxes or Other Taxes
imposed by any  jurisdiction  on amounts payable under this Section 2.12 imposed
on or paid by such  Lender or the  Agent  (as the case may be) or any  liability
(including penalties, additions to tax, 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 Lender or the Agent makes written demand therefor.

     (d) Within 30 days after the date of any  payment  of Taxes,  the  Borrower
shall  furnish to the Agent,  at its address  referred to in Section  8.02,  the
original receipt of payment or a certified copy of such receipt. If no Taxes are
payable in respect of any payment  hereunder  or under the Notes,  the  Borrower
shall furnish to the Agent, at such address, a certificate from each appropriate
taxing authority,  or an opinion of counsel acceptable to the Lenders, in either
case stating that such payment is exempt from or not subject to Taxes.

     (e) Each  Lender  organized  under the laws of a  jurisdiction  outside the
United States shall, on the Effective Date in the case of the Initial Lender and
on the date of the  Assignment  and  Acceptance  pursuant  to which it  became a
Lender in the case of each other  Lender,  and from time to time  thereafter  if
requested  in  writing  by the  Borrower  or the Agent (but only so long as such
Lender  remains  lawfully  able to do so),  provide each of the Borrower and the
Agent with Internal  Revenue Service form 1001 or 4224, as  appropriate,  or any
successor or other form prescribed by the Internal Revenue  Service,  certifying
that such Lender is exempt from or entitled to a reduced  rate of United  States
withholding tax on payments of interest pursuant to this Agreement or the Notes.
If the form  provided by such Lender at the time such Lender  becomes a party to
this Agreement indicates a United States interest withholding tax rate in excess
of zero,  withholding  tax at such rate shall be considered  excluded from Taxes
unless and until such Lender  provides the  appropriate  form  certifying that a
lesser rate applies, whereupon withholding tax at such lesser rate only shall be
considered  excluded  from Taxes for periods  governed  by such form;  provided,
however, that, if at the date of the Assignment and Acceptance pursuant to which
a Lender becomes a party to this Agreement,  the Lender assignor was entitled to
payments under Section 2.12(a) in respect of United States  withholding tax with
respect to interest  paid at such date,  then,  to such  extent,  the term Taxes
shall  include  (in  addition  to  withholding  taxes that may be imposed in the
future or other amounts otherwise includable in Taxes) United States withholding
tax, if any, applicable with respect to the Lender assignee on such date. If any
form or document  referred to in this  subsection (e) requires the disclosure of
information,  other than  information  necessary  to compute the tax payable and
information required on the date hereof by Internal Revenue Service form 1001 or
4224, that the Lender reasonably considers to be confidential,  the Lender shall
give notice  thereof to the  Borrower  and shall not be  obligated to include in
such form or document such confidential information.

     (f) For any period with respect to which a Lender has failed to provide the
Borrower with the  appropriate  form described in Section 2.12(e) (other than if
such failure is due to a change in law occurring subsequent to the date on which
a form originally was required to be provided,  or if such form otherwise is not
required under the first sentence of Section 2.12(e)  above),  such Lender shall
not be entitled to  indemnification  under Section 2.12(a) with respect to Taxes
imposed by the United States; provided,  however, that should such Lender become
subject to Taxes  because of its failure to deliver a form  required  hereunder,
the Borrower  shall take such steps as such Lender shall  reasonably  request to
assist such Lender to recover such Taxes.

     SECTION  2.13.  Sharing of  Payments,  Etc. If any Lender  shall obtain any
payment (whether  voluntary,  involuntary,  through the exercise of any right of
setoff, or otherwise) on account of the Advance owing to it (other than pursuant
to Section 2.09,  2.12 or 8.04(c)) in excess of its ratable share of payments on
account of the Advances obtained by all the Lenders, such Lender shall forthwith
purchase from the other  Lenders such  participations  in the Advances  owing to
them as shall be necessary to cause such  purchasing  Lender to share the excess
payment ratably with each of them; provided, however, that if all or any portion
of such excess payment is thereafter recovered from such purchasing Lender, such
purchase  from each Lender shall be rescinded and such Lender shall repay to the
purchasing  Lender the purchase  price to the extent of such  recovery  together
with an amount equal to such Lender's ratable share (according to the proportion
of (a) the amount of such Lender's required repayment to (b) the total amount so
recovered  from the  purchasing  Lender) of any interest or other amount paid or
payable by the  purchasing  Lender in respect of the total amount so  recovered.
The Borrower agrees that any Lender so purchasing a  participation  from another
Lender  pursuant to this  Section 2.13 may, to the fullest  extent  permitted by
law,  exercise  all its rights of payment  (including  the right of setoff) with
respect  to such  participation  as fully  as if such  Lender  were  the  direct
creditor of the Borrower in the amount of such participation.

     SECTION  2.14.  Use of  Proceeds.  The  proceeds of the  Advances  shall be
available (and the Borrower  agrees that it shall use such proceeds)  solely for
general corporate purposes of the Borrower and its Subsidiaries.

     SECTION  3.03.   Determinations   Under  Section  3.01.   For  purposes  of
determining  compliance  with the  conditions  specified in Section  3.01,  each
Lender  shall be deemed to have  consented  to,  approved  or  accepted or to be

to or approved by or acceptable or satisfactory to the Lenders unless an officer
of the Agent  responsible  for the  transactions  contemplated by this Agreement
shall have received notice from such Lender prior to the date that the Borrower,
by notice to the Lenders,  designates as the proposed Effective Date, specifying
its  objection  thereto.  The Agent  shall  promptly  notify the  Lenders of the
occurrence of the Effective Date.


                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES

     SECTION 4.01.  Representations and Warranties of the Borrower. The Borrower
represents and warrants as follows:

     (a) The Borrower is a corporation  duly organized,  validly existing and in
good standing under the laws of the State of Delaware.

     (b)  The  execution,  delivery  and  performance  by the  Borrower  of this
Agreement and the Notes are within the Borrower's  corporate  powers,  have been
duly authorized by all necessary corporate action, and do not contravene (i) the
Borrower's  charter or by-laws  or (ii) any law or any  contractual  restriction
binding on or affecting the Borrower.

     (c) No  authorization  or approval or other  action by, and no notice to or
filing with,  any  Governmental  Authority  is required  for the due  execution,
delivery and performance by the Borrower of this Agreement and the Notes.

     (d) This Agreement has been,  and the Notes when  delivered  hereunder will
have been,  duly executed and delivered by the Borrower.  This Agreement is, and
each of the Notes when  delivered  hereunder  will be, legal,  valid and binding
obligations of the Borrower  enforceable against the Borrower in accordance with
their respective terms.

     (e) The Consolidated  balance sheet of the Borrower and its Subsidiaries as
at December 31, 1996, and the related Consolidated statements of income and cash
flows of the  Borrower  and its  Subsidiaries  for the fiscal  year then  ended,
copies of which have been furnished to the Lenders, fairly present the financial
condition of the Borrower and its  Subsidiaries  as at such date and the results
of the operations of the Borrower and its  Subsidiaries  for the period ended on
such date, all in accordance with GAAP.  Since December 31, 1996, there has been
no Material Adverse Change.

     (f) There is no pending or threatened  action or  proceeding  affecting the
Borrower or any of its  Subsidiaries  before any court,  governmental  agency or

     (g) The Borrower is not engaged in the business of extending credit for the
purpose of purchasing or carrying margin stock (within the meaning of Regulation
U issued  by the Board of  Governors  of the  Federal  Reserve  System),  and no
proceeds of any Advance will be used to purchase or carry any margin stock or to
extend  credit to others for the purpose of  purchasing  or carrying  any margin
stock.

     (h) The Advances  and all related  obligations  of the Borrower  under this
Agreement and the Notes rank pari passu with all other unsecured  obligations of
the Borrower that are not, by their terms,  expressly  subordinate to such other
obligations of the Borrower.


                                    ARTICLE V
                            COVENANTS OF THE BORROWER

     SECTION  5.01.  Affirmative  Covenants.  On and after the Change of Control
Date and so long as any Advance shall remain unpaid or any Lender shall have any
Commitment  hereunder,  the Borrower  will,  unless the Lenders shall  otherwise
consent in writing:

     (a) Compliance with Laws, Etc.  Comply,  and cause each of its Subsidiaries
to  comply,  in  all  material  respects,   with  all  applicable  laws,  rules,
regulations  and  orders,  such  compliance  to  include,   without  limitation,
compliance with ERISA and environmental laws.

     (b)  Payment  of Taxes,  Etc.  Pay and  discharge,  and  cause  each of its
Subsidiaries to pay and discharge,  before the same shall become delinquent, (i)
all taxes,  assessments  and  governmental  charges or levies imposed upon it or
upon its  property  and (ii) all lawful  claims  that,  if unpaid,  might by law
become a lien upon its property;  provided,  however,  that neither the Borrower
nor any of its Subsidiaries  shall be required to pay or discharge any such tax,
assessment,  charge or claim that is being contested in good faith and by proper
proceedings and as to which appropriate  reserves are being  maintained,  unless
and until any lien  resulting  therefrom  attaches to its  property  and becomes
enforceable against its other creditors.

     (c) Preservation of Corporate  Existence,  Etc. Preserve and maintain,  and
cause  each  of  its  Subsidiaries  to  preserve  and  maintain,  its  corporate
existence,  rights  (charter and statutory) and franchises;  provided,  however,
that  neither  the  Borrower  nor any of its  Subsidiaries  shall be required to
preserve  any right or  franchise  if the board of  directors of the Borrower or
such  Subsidiary  shall  determine  that the  preservation  thereof is no longer
desirable in the conduct of the business of the Borrower or such Subsidiary,  as
the  case  may be,  and that the  loss  thereof  is not  disadvantageous  in any
material respect to the Borrower, such Subsidiary or the Lenders.

     (d) Keeping of Books.  Keep,  and cause each of its  Subsidiaries  to keep,
proper books of record and account,  in which full and correct  entries shall be
made of all financial  transactions  and the assets and business of the Borrower
and  each  such  Subsidiary  in  accordance  with  GAAP  or,  in the case of any
Subsidiary  organized  under the laws of a  jurisdiction  other  than the United
States  or any  state  thereof,  the  equivalent  of  GAAP  applicable  in  such
jurisdiction.

     (e) Maintenance of Properties,  Etc. Maintain and preserve,  and cause each
of its  Subsidiaries  to maintain and preserve,  all of its properties  that are
used or  useful  in the  conduct  of its  business  in good  working  order  and
condition, ordinary wear and tear excepted.

     (f) Reporting Requirements. Furnish to the Lenders:

          (i) as soon as available and in any event within 45 days after the end
     of each of the first three  quarters  of each fiscal year of the  Borrower,

     end of such quarter and Consolidated statements of income and cash flows of
     the Borrower and its Subsidiaries  for the period  commencing at the end of
     the  previous  fiscal  year and ending with the end of such  quarter,  duly
     certified  (subject to year-end audit  adjustments)  by the chief financial
     officer of the Borrower as having been prepared in accordance with GAAP and

     demonstrate  compliance with  subsections  (g), (h) and (i) of this Section
     4.01;

     balance sheets of the Borrower and its  Subsidiaries  as of the end of such
     fiscal  year and  Consolidated  statements  of income and cash flows of the
     Borrower  and  its   Subsidiaries  for  such  fiscal  year,  in  each  case
     accompanied by an opinion acceptable to the Lenders by KPMG Peat Marwick or
     other independent public accountants  reasonably  acceptable to the Lenders
     and  setting  forth in  reasonable  detail the  calculations  necessary  to
     demonstrate  compliance with  subsections  (g), (h) and (i) of this Section
     4.01;

     details of such  Default  and the action  that the  Borrower  has taken and
     proposes to take with respect thereto;

          (iv)  promptly  after the  sending  or filing  thereof,  copies of all
     reports which the Borrower sends to any of its securityholders,  and copies
     of all reports and registration statements which the Borrower or any of its
     Subsidiaries  files with the  Securities  and  Exchange  Commission  or any
     national securities exchange;

          (v)  promptly  after the filing or  receiving  thereof,  copies of all

after the  applicable  grace  period,  if any,  specified  in the  agreement  or
instrument  relating to such Debt;  or any other event shall occur or  condition
shall  exist under any  agreement  or  instrument  relating to any such Debt and

judgment  or order or (ii)  there  shall be any  period of 30  consecutive  days
during which a stay of  enforcement  of such  judgment or order,  by reason of a
pending appeal or otherwise, shall not be in effect;

then, and in any such event, the Agent (i) shall at the request, or may with the

each  Lender  to make  Advances  to be  terminated,  whereupon  the  same  shall
forthwith terminate,  and (ii) shall at the request, or may with the consent, of
the Lenders, by notice to the Borrower,  declare the Notes, all interest thereon
and all other  amounts  payable  under this  Agreement to be  forthwith  due and

                                   ARTICLE VII
                                    THE AGENT

     SECTION 7.01.  Authorization  and Action.  Each Lender hereby  appoints and
authorizes  the Agent to take such action as agent on its behalf and to exercise
such powers and discretion under this Agreement as are delegated to the Agent by
the terms  hereof,  together with such powers and  discretion as are  reasonably
incidental  thereto.  As to any  matters  not  expressly  provided  for by  this
Agreement  (including,  without  limitation,  enforcement  or  collection of the
Notes),  the Agent shall not be required to exercise any  discretion or take any
action,  but shall be  required  to act or to refrain  from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the  Lenders,  and such  instructions  shall be binding upon all Lenders and all
holders of Notes;  provided,  however,  that the Agent  shall not be required to
take any action that exposes the Agent to personal liability or that is contrary
to this  Agreement  or  applicable  law. The Agent agrees to give to each Lender
prompt  notice of each notice given to it by the Borrower  pursuant to the terms
of this Agreement.

     SECTION  7.02.  Agent's  Reliance,  Etc.  Neither  the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or
omitted to be taken by it or them under or in  connection  with this  Agreement,
except  for its or their own gross  negligence  or willful  misconduct.  Without
limitation of the  generality  of the  foregoing,  the Agent:  (a) may treat the
payee of any Note as the holder  thereof until the Agent receives and accepts an
Assignment and  Acceptance  entered into by the Lender that is the payee of such
Note, as assignor, and an Eligible Assignee, as assignee, as provided in Section
8.07; (b) may consult with legal counsel  (including  counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable  for any  action  taken or  omitted  to be  taken in good  faith by it in
accordance with the advice of such counsel, accountants or experts; (c) makes no
warranty or  representation  to any Lender and shall not be  responsible  to any
Lender for any statements,  warranties or  representations  (whether  written or
oral) made in or in connection with this Agreement;  (d) shall not have any duty
to ascertain or to inquire as to the  performance  or  observance  of any of the
terms,  covenants or conditions of this Agreement on the part of the Borrower or
to inspect the property  (including the books and records) of the Borrower;  (e)
shall  not be  responsible  to any  Lender  for  the  due  execution,  legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement or
any other instrument or document  furnished pursuant hereto; and (t) shall incur
no  liability  under or in respect of this  Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telecopier,
telegram or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

     SECTION 7.03. Huls. With respect to its Commitment,  the Advance made by it
and the Note issued to it, Huls shall have the same rights and powers under this
Agreement  as any other  Lender and may  exercise the same as though it were not
the Agent; and the term "Lender" or "Lenders" shall,  unless otherwise expressly
indicated, include Huls in its individual capacity.

     SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it has,
independently  and without reliance upon the Agent or any other Lender and based
on the financial statements referred to in Section 4.01 and such other documents
and information as it has deemed  appropriate,  made its own credit analysis and
decision to enter into this  Agreement.  Each Lender also  acknowledges  that it
will,  independently and without reliance upon the Agent or any other Lender and
based on such  documents and  information  as it shall deem  appropriate  at the
time,  continue to make its own credit  decisions in taking or not taking action
under this Agreement.

     SECTION 7.05. Indemnification. The Lenders agree to indemnify the Agent (to
the extent not reimbursed by the Borrower),  ratably according to the respective
principal  amounts of the Notes then held by each of them (or if no Notes are at
the time  outstanding  or if any Notes are held by Persons that are not Lenders,
ratably  according to the  respective  amounts of their  Commitments),  from and
against  any and  all  liabilities,  obligations,  losses,  damages,  penalties,
actions,  judgments,  suits,  costs,  expenses or  disbursements  of any kind or
nature  whatsoever that may be imposed on, incurred by, or asserted  against the
Agent in any way  relating  to or arising  out of this  Agreement  or any action
taken or omitted  by the Agent  under this  Agreement,  provided  that no Lender
shall be  liable  for any  portion  of such  liabilities,  obligations,  losses,
damages, penalties,  actions, judgments, suits, costs, expenses or disbursements
resulting  from the Agent's  gross  negligence  or willful  misconduct.  Without
limitation of the foregoing,  each Lender agrees to reimburse the Agent promptly
upon  demand for its  ratable  share of any  out-of-pocket  expenses  (including
counsel  fees)  incurred  by the  Agent  in  connection  with  the  preparation,
execution,  delivery,  administration,  modification,  amendment or  enforcement
(whether  through  negotiations,  legal  proceedings  or otherwise) of, or legal
advice in respect of rights or  responsibilities  under, this Agreement,  to the
extent that the Agent is not reimbursed for such expenses by the Borrower.

     SECTION 7.06.  Successor  Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower and may be removed at any
time with or without cause by the all of the Lenders.  Upon any such resignation
or removal, the Lenders shall have the right to appoint a successor Agent. If no
successor  Agent shall have been so  appointed  by the  Lenders,  and shall have
accepted such  appointment,  within 30 days after the retiring Agent's giving of
notice of resignation or the Lenders'  removal of the retiring  Agent,  then the
retiring Agent may, on behalf of the Lenders,  appoint a successor Agent,  which
shall be a commercial  bank organized  under the laws of the United States or of
any state thereof and having a long-term  senior unsecured debt rating by S&P of
"A" or better.  Upon the acceptance of any  appointment as Agent  hereunder by a
successor  Agent,  such successor  Agent shall  thereupon  succeed to and become
vested with all the rights,  powers,  discretion,  privileges  and duties of the
retiring  Agent,  and the retiring Agent shall be discharged from its duties and
obligations  under this  Agreement.  After any retiring  Agent's  resignation or
removal  hereunder as Agent,  the  provisions of this Article VII shall inure to
its  benefit as to any  actions  taken or omitted to be taken by it while it was
Agent under this Agreement.


                                  ARTICLE VIII
                                  MISCELLANEOUS

     SECTION 8.01.  Amendments,  Etc. No amendment or waiver of any provision of
this  Agreement  or the Notes,  nor  consent to any  departure  by the  Borrower
therefrom,  shall in any event be effective  unless the same shall be in writing
and signed by the  Required  Lenders,  and then such waiver or consent  shall be
effective only in the specific  instance and for the specific  purpose for which
given; provided,  however, that no amendment, waiver or consent shall, unless in
writing and signed by all the Lenders, do any of the following: (a) waive any of
the conditions  specified in Section 3.01,  (b) increase the  Commitments of the
Lenders or subject the  Lenders to any  additional  obligations,  (c) reduce the
principal  of, or interest  on, the Notes or any fees or other  amounts  payable

amount of the Notes,  or the number of Lenders,  that shall be required  for the
Lenders or any of them to take any action  hereunder  or (f) amend this  Section
8.01; and provided further that no amendment, waiver or consent shall, unless in
writing and signed by the Agent in addition  to the  Lenders  required  above to
take such action,  affect the rights or duties of the Agent under this Agreement
or any Note.

     SECTION 8.02. Notices,  Etc. All notices and other communications  provided
for  hereunder  shall be in writing  (including  telecopier  communication)  and

     SECTION 8.03. No Waiver;  Remedies. No failure on the part of any Lender or
the Agent to exercise, and no delay in exercising,  any right hereunder or under
any Note  shall  operate  as a waiver  thereof;  nor shall any single or partial
exercise of any such right preclude any other or further exercise thereof or the
exercise of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

     SECTION 8.04. Costs and Expenses.  (a) The Borrower agrees to pay on demand
all  reasonable  costs  and  expenses  of  the  Agent  in  connection  with  the

limitation,  the  reasonable  fees and  expenses  of counsel  for the Agent with
respect  thereto  and with  respect to  advising  the Agent as to its rights and

Lender and each of their  Affiliates and their officers,  directors,  employees,
agents and advisors (each, an "Indemnified  Party") from and against any and all
claims,   damages,   losses,   liabilities  and  expenses  (including,   without
limitation,  reasonable fees and expenses of counsel) that may be incurred by or
asserted or awarded against any  Indemnified  Party, in each case arising out of
or in connection with or by reason of, or in connection with the preparation for
a defense  of, any  investigation,  litigation  or  proceeding  arising  out of,
related  to or in  connection  with  the  Notes,  this  Agreement,  any  of  the
transactions  contemplated  herein or the actual or proposed use of the proceeds
of the Advances, whether or not such investigation,  litigation or proceeding is
brought  by  the  Borrower,  its  directors,  shareholders  or  creditors  or an
Indemnified  Party or any other Person or any  Indemnified  Party is otherwise a
party  thereto  and  whether  or not the  transactions  contemplated  hereby are
consummated, except to the extent such claim, damage, loss, liability or expense
is found in a final, nonappealable judgment by a court of competent jurisdiction
to have  resulted  from such  Indemnified  Party's  gross  negligence or willful
misconduct.  The Borrower also agrees not to assert any claim against the Agent,
any  Lender,  any of their  Affiliates,  or any of their  respective  directors,
officers,  employees,  attorneys  and agents,  on any theory of  liability,  for
special, indirect, consequential or punitive damages arising out of or otherwise
relating to the Notes,  this  Agreement,  any of the  transactions  contemplated
herein or the actual or proposed use of the proceeds of the Advances.

     (c) If any prepayment is made by the Borrower pursuant to Section 2.08, the
Borrower shall, upon demand by the Initial Lender, pay to the Initial Lender the
amount  required to compensate  the Initial  Lender for any loss of  anticipated

(but not less than $O) between (i) the present value of the aggregate  amount of
interest payments that would have become due on the principal amount prepaid had
such amount not been  prepaid  and (ii) the present  value of the rate of return
anticipated in respect of the reemployment or investment of the proceeds of such
principal  amount prepaid for the period of equal to the period from the date of
such  prepayment to the Repayment  Date. The Initial Lender shall use good faith
in the  reemployment  or investment of the proceeds of such  prepayment  and the
determination of any amount payable by the Borrower under this Section 8.04(c).

     (d)  Without  prejudice  to the  survival  of any  other  agreement  of the

each Lender and each of its Affiliates is hereby authorized at any time and from
time to time, 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 and other  indebtedness  at any time owing by such  Lender or such
Affiliate  to or for the credit or the account of the  Borrower  against any and
all of the  obligations  of the Borrower now or  hereafter  existing  under this
Agreement  and the Note held by such  Lender,  whether or not such Lender  shall
have  made any  demand  under  this  Agreement  or such Note and  although  such
obligations may be unmatured. Each Lender agrees promptly to notify the Borrower
after any such setoff and  application,  provided  that the failure to give such
notice shall not affect the validity of such setoff and application.  The rights
of each Lender and its  Affiliates  under this  Section  8.05 are in addition to
other  rights and  remedies  (including,  without  limitation,  other  rights of
setoff) that such Lender and its Affiliates may have.

the Advance  owing to it and the Note or Notes held by it);  provided,  however,
that  (i)  each  such  assignment  shall be of a  constant,  and not a  varying,
percentage of all rights and obligations  under this  Agreement,  (ii) except in
the  case  of  an  assignment  to a  Person  that,  immediately  prior  to  such
assignment,  was a Lender  or an  assignment  of all of a  Lender's  rights  and
obligations under this Agreement,  the amount of the Commitment of the assigning
Lender being  assigned  pursuant to each such  assignment  (determined as of the
date of the Assignment and Acceptance with respect to such assignment)  shall in
no event be less than $5,000,000 or an integral multiple of $1,000,000 in excess
thereof,  (iii) each such assignment shall be to an Eligible Assignee,  and (iv)
the parties to each such assignment  shall execute and deliver to the Agent, for
its  acceptance  and recording in the Register,  an Assignment  and  Acceptance,
together  with  any  Note  subject  to such  assignment.  Upon  such  execution,

assigned to it pursuant to such Assignment and  Acceptance,  have the rights and
obligations of a Lender hereunder and (B) the Lender assignor  thereunder shall,
to the extent that rights and  obligations  hereunder  have been  assigned by it
pursuant  to such  Assignment  and  Acceptance,  relinquish  its  rights  and be
released  from its  obligations  under this  Agreement  (and,  in the case of an
Assignment and Acceptance  covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto).

     (b) By executing and  delivering an Assignment and  Acceptance,  the Lender
assignor  thereunder and the assignee  thereunder confirm to and agree with each
other and the other  parties  hereto as  follows:  (i) other than as provided in
such Assignment and Acceptance, such assigning Lender makes no representation or
warranty  and  assumes  no  responsibility   with  respect  to  any  statements,
warranties or  representations  made in or in connection  with this Agreement or
the execution, legality, validity, enforceability,  genuineness,  sufficiency or
value of this Agreement or any other instrument or document  furnished  pursuant
hereto;  (ii) such  assigning  Lender  makes no  representation  or warranty and
assumes  no  responsibility  with  respect  to the  financial  condition  of the
Borrower  or  the  performance  or  observance  by  the  Borrower  of any of its
obligations  under this Agreement or any other instrument or document  furnished
pursuant  hereto;  (iii) such  assignee  confirms that it has received a copy of
this Agreement,  together with copies of the financial statements referred to in
Section  4.01  and  such  other  documents  and  information  as it  has  deemed
appropriate  to make its own credit  analysis  and  decision  to enter into such
Assignment and Acceptance;  (iv) such assignee will,  independently  and without
reliance upon the Agent,  such assigning Lender or any other Lender and based on
such  documents  and  information  as it shall  deem  appropriate  at the  time,
continue to make its own credit  decisions in taking or not taking  action under
this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi)
such assignee  appoints and authorizes the Agent to take such action as agent on
its behalf and to exercise such powers and  discretion  under this  Agreement as
are  delegated to the Agent by the terms  hereof,  together with such powers and
discretion as are reasonably  incidental thereto; and (vii) such assignee agrees
that it will perform in accordance with their terms all of the obligations  that
by the terms of this Agreement are required to be performed by it as a Lender.

     (c) The Agent shall  maintain at its address  referred to in Section 8.02 a
copy of each  Assignment  and  Acceptance  delivered to and accepted by it and a
register for the  recordation  of the names and addresses of the Lenders and the
Commitment  of, and principal  amount of the Advances owing to, each Lender from
time to time (the  "Register").  The entries in the Register shall be conclusive
and binding for all purposes, absent manifest error, and the Borrower, the Agent
and the Lenders may treat each Person  whose name is recorded in the Register as
a Lender  hereunder for all purposes of this  Agreement.  The Register  shall be
available for  inspection by the Borrower or any Lender at any  reasonable  time
and from time to time upon reasonable prior notice.

     (d) Upon  its  receipt  of an  Assignment  and  Acceptance  executed  by an
assigning Lender and an assignee  representing that it is an Eligible  Assignee,
together with any Note or Notes subject to such assignment,  the Agent shall, if
such  Assignment and Acceptance has been completed and is in  substantially  the
form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii) record
the information  contained  therein in the Register and (iii) give prompt notice
thereof to the  Borrower.  Within five  Business  Days after its receipt of such
notice, the Borrower, at its own expense, shall execute and deliver to the Agent
in exchange for the  surrendered  Note a new Note to the order of such  Eligible
Assignee  in an amount  equal to the  Commitment  assumed by it pursuant to such
Assignment and Acceptance and, if the assigning Lender has retained a Commitment
hereunder, a new Note to the order of the assigning Lender in an amount equal to
the Commitment  retained by it hereunder.  Such new Note or Notes shall be in an
aggregate  principal  amount  equal to the  aggregate  principal  amount of such
surrendered Note or Notes,  shall be dated the effective date of such Assignment
and Acceptance  and shall  otherwise be in  substantially  the form of Exhibit A
hereto.

     (e) Each  Lender  may  sell  participations  to one or more  banks or other
entities  (other than the Borrower or any of its  Affiliates)  in or to all or a
portion of its rights and obligations under this Agreement  (including,  without
limitation, all or a portion of its Commitment, the Advances owing to it and the
Note or Notes held by it); provided, however, that (i) such Lender's obligations
under this  Agreement  (including,  without  limitation,  its  Commitment to the
Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender  shall  remain the holder of any such Note for all purposes of
this  Agreement,  (iv) the  Borrower,  the  Agent and the  other  Lenders  shall
continue to deal solely and directly  with such Lender in  connection  with such
Lender's  rights and  obligations  under this  Agreement and (v) no  participant
under any such  participation  shall have any right to approve any  amendment or
waiver of any  provision of this  Agreement  or any Note,  or any consent to any
departure by the Borrower  therefrom,  except to the extent that such amendment,
waiver or consent  would reduce the  principal  of, or interest on, the Notes or
any fees or other amounts payable hereunder,  in each case to the extent subject
to such  participation,  or postpone any date fixed for any payment of principal
of, or interest on, the Notes or any fees or other amounts payable hereunder, in
each case to the extent subject to such participation.

     (f) Any Lender may, in connection with any assignment or  participation  or
proposed assignment or participation  pursuant to this Section 8.07, disclose to
the assignee or participant or proposed assignee or participant, any information
relating  to the  Borrower  furnished  to such  Lender  by or on  behalf  of the
Borrower;  provided  that,  prior  to  any  such  disclosure,  the  assignee  or
participant  or proposed  assignee or  participant  shall agree to preserve  the
confidentiality  of  any  Confidential  Information  relating  to  the  Borrower
received by it from such Lender.

     (g)  Notwithstanding  any other provision set forth in this Agreement,  any
Lender may at any time  create a security  interest in all or any portion of its
rights under this Agreement (including,  without limitation,  the Advances owing
to it and  the  Note  held  by it) in  favor  of any  Federal  Reserve  Bank  in
accordance  with  Regulation A of the Board of Governors of the Federal  Reserve
System.

     (h)  In  connection  with  the  initial   assignment  or  proposed  initial
assignment by the Initial  Lender  pursuant to this Section  8.07,  the Borrower
shall,  upon the request of the Initial Lender,  furnish to the Initial Lender a
favorable opinion of counsel for the Borrower  acceptable to the Initial Lender,
in form and substance reasonably satisfactory to the Initial Lender.

     SECTION  8.08.  Confidentiality.  Neither  the Agent nor any  Lender  shall
disclose any  Confidential  Information to any Person without the consent of the
Borrower,  other than (a) to the Agent's or such Lender's  Affiliates  and their
officers, directors, employees, agents and advisors and to actual or prospective
assignees and  participants,  and then, in each case, only on a confidential and
need-to-know  basis,  (b) as required by any law, rule or regulation or judicial
process  and (c) as  requested  or  required  by any  state,  federal or foreign
authority or examiner regulating banks or banking.

     SECTION 8.09. Governing Law. This Agreement and the Notes shall be governed
by, and construed in accordance with, the laws of the State of New York.

     SECTION 8.10. Execution in Counterparts.  This Agreement may be executed in
any  number  of  counterparts  and  by  different  parties  hereto  in  separate
counterparts,  each of which when so executed  shall be deemed to be an original
and all of which taken  together shall  constitute  one and the same  agreement.
Delivery of an executed  counterpart  of a signature  page to this  Agreement by
telecopier shall be effective as delivery of a manually executed  counterpart of
this Agreement.

     SECTION  8.11.  Jurisdiction,  Etc. (a) Each of the parties  hereto  hereby
irrevocably and  unconditionally  submits,  for itself and its property,  to the
nonexclusive  jurisdiction  of any New York State court or federal  court of the
United States of America  sitting in New York City, and any appellate court from
any  thereof,  in any action or  proceeding  arising  out of or relating to this
Agreement or the Notes, or for  recognition or enforcement of any judgment,  and
each of the parties hereto hereby  irrevocably and  unconditionally  agrees that
all  claims  in  respect  of any such  action  or  proceeding  may be heard  and
determined in any such New York State court or, to the extent  permitted by law,
in such federal  court.  Each of the parties hereto agrees that a final judgment
in any such  action or  proceeding  shall be  conclusive  and may be enforced in
other  jurisdictions  by suit on the judgment or in any other manner provided by
law.  Nothing  in this  Agreement  shall  affect  any  right  that any party may
otherwise  have to bring any action or proceeding  relating to this Agreement or
the Notes in the courts of any jurisdiction.

     (b) Each of the parties hereto irrevocably and  unconditionally  waives, to
the fullest  extent it may legally and  effectively do so, any objection that it
may now or  hereafter  have to the  laying  of  venue  of any  suit,  action  or
proceeding  arising out of or relating to this Agreement or the Notes in any New
York State or federal  court.  Each of the  parties  hereto  hereby  irrevocably
waives,  to the fullest extent  permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

     IN WITNESS  WHEREOF,  the parties  hereto have caused this  Agreement to be
executed by their respective officers thereunto duly authorized,  as of the date
first above written.
