aggregated with all amounts to be converted to a Eurodollar Advance on such date
and having the same  Interest  Period as such first  Eurodollar  Advance,  shall
equal no less than $500,000 or such amount plus a whole  multiple of $100,000 in
excess  thereof,  and (ii) each ABR Advance  made on each  Borrowing  Date shall
equal no less than $500,000 or such amount plus a whole  multiple of $100,000 in
excess thereof or, if less, the Available Parent  Commitment  Amount in the case
of the Parent Facility.

<PAGE>

     (b) Upon receipt of each Borrowing Request, the Agent shall promptly notify
each Lender  thereof.  Subject to its  receipt of the notice  referred to in the
preceding sentence, each Lender will make available to the Agent for the account
of the applicable  Borrower at the office of the Agent set forth in Section 11.2
not later than 12:00  noon on the  relevant  Borrowing  Date  requested  by such
Borrower, in funds immediately available to the Agent at such office, the amount
of its Parent Commitment Percentage of the requested Revolving Credit Loans. The
amounts so made available to the Agent on such Borrowing Date will then, subject
to the satisfaction of the terms and conditions of this Agreement, as determined
by the Agent,  be made available on such date to the applicable  Borrower by the
Agent at the office of the Agent  specified  in  Section  11.2 by  crediting  an
account of such  Borrower on the books of such office with the aggregate of said
amounts received by the Agent.

     (c) Unless the Agent  shall have  received  prior  notice from a Lender (by
telephone  or  otherwise,  such notice to be promptly  confirmed  by telecopy or
other  writing)  that such  Lender  will not make  available  to the Agent  such
Lender's applicable  Commitment  Percentage of the applicable Loans requested by
the  applicable  Borrower,  the Agent may assume  that such Lender has made such
share  available  to the Agent on the  Borrowing  Date in  accordance  with this
Section,  provided that such Lender  received notice of the requested Loans from
the Agent, and the Agent may, in reliance upon such  assumption,  make available
to the applicable Borrower on the Borrowing Date a corresponding  amount. If and
to the  extent  such  Lender  shall not have so made its  applicable  Commitment
Percentage of such Loans available to the Agent,  such Lender and the applicable
Borrower  severally  agree  to  pay  to  the  Agent  forthwith  on  demand  such
corresponding amount (to the extent not previously paid by the other),  together
with interest  thereon for each day from the date such amount is made  available
to the  applicable  Borrower to the date such amount is paid to the Agent,  at a
rate per annum equal to, in the case of such Borrower,  the applicable  interest
rate set forth in Section 3.1 for ABR Advances, and, in the case of such Lender,
at a rate of interest  per annum  equal to the Federal  Funds Rate for the first
three days  after the due date of such  payment  until the date such  payment is
received  by the Agent and the  Federal  Funds  Rate  plus 2%  thereafter.  Such
payment by such  Borrower,  however,  shall be without  prejudice  to its rights
against  such Lender.  If such Lender shall pay to the Agent such  corresponding
amount, such amount so paid shall constitute such Lender's Revolving Credit Loan
and/or  Term  Loan,  as the case may be as part of the  Revolving  Credit  Loans
and/or Term Loans,  as the case may be, for  purposes of this  Agreement,  which
such Loan shall be deemed to have been made by such Lender on the Borrowing Date
applicable to such Loans.

     (d) If a Lender makes a new Revolving  Credit Loan to Parent on a Borrowing
Date on which Parent is to repay a Revolving Credit Loan from such Lender,  such
Lender shall apply the proceeds of such new  Revolving  Credit Loan to make such
repayment, and only the excess of the proceeds of such new Revolving Credit Loan
over the Revolving Credit Loan being repaid need be made available to the Agent.

2.4  Termination or Reduction of Parent Commitments and GP Canada Credit
Exposure

     (a) Voluntary  Reductions.  The Parent shall have the right,  upon at least
three Business Days' prior written notice to the Agent, (i) at any time when the
Aggregate  Parent Credit Exposure shall be zero or at any time the Parent elects
to pay or to prepay the Revolving  Credit Loans in their entirety,  to terminate
the Parent Commitments of all of the Lenders, and (ii) at any time and from time
to time when the Aggregate Parent  Commitment  Amount shall exceed the Aggregate
Parent Credit Exposure,  to permanently  reduce the Aggregate Parent  Commitment
Amount by a sum not greater than the amount of such excess,  provided,  however,
that each such partial  reduction  shall be in the amount of  $1,000,000 or such
amount plus a whole multiple of $500,000 in excess thereof.

     (b) Mandatory Reductions Relating to Insurance.  Subject to Section 2.2(c),
the  Aggregate  Parent  Commitment  Amount and the  Aggregate  GP Canada  Credit
Exposure,  as the case may be, shall be permanently  reduced by the amounts,  at
the times and to the extent required by Section 7.5(b).

     (c) Intentionally Omitted.

     (d) Intentionally Omitted.

     (e) In General.  Each reduction of the Aggregate Parent  Commitment  Amount
and/or Aggregate GP Canada Credit Exposure, as the case may be, shall be made by
(i) in the  case  of the  Parent  Facility  reducing  each  Lender's  applicable
Commitment  Amount by an amount  equal to such  Lender's  applicable  Commitment
Percentage  of such  reduction  and (ii) in the case of the GP Canada  Facility,
subject to Section 2.2(c),  reducing each Lender's  outstanding  Term Loan by an
amount  equal  to  such  Lender's  Commitment   Percentage  of  such  reduction.
Simultaneously  with each reduction of the Aggregate  Parent  Commitment  Amount
under this Section,  Parent shall pay the Parent  Commitment  Fee accrued on the
amount by which the Aggregate Parent Commitment Amount has been reduced.

2.5  Prepayments of Loans; Overadvance Reductions; Additional Collateral

     (a) Voluntary Prepayments.  A Borrower may, at its option, prepay its Loans
without  premium or penalty (but subject to Section 3.5), in full at any time or
in part  from  time to time by  notifying  the  Agent in  writing  at least  one
Business  Day  prior  to the  proposed  prepayment  date,  in the  case of Loans
consisting  of ABR  Advances  and at  least  three  Business  Days  prior to the
proposed  prepayment  date,  in the  case  of  Loans  consisting  of  Eurodollar
Advances,  specifying  whether the Loans to be prepaid  consist of ABR Advances,

<PAGE>

Eurodollar  Advances,  or a  combination  thereof,  the Loan to be prepaid,  the
amount to be  prepaid  and the date of  prepayment.  Each such  notice  shall be
irrevocable  and the  amount  specified  in each  such  notice  shall be due and
payable on the date  specified,  together  with accrued  interest to the date of
such payment on the amount prepaid. Upon receipt of such notice, the Agent shall
promptly notify each Lender thereof.  Each partial  prepayment of Loans pursuant
to this subsection shall be in an aggregate principal amount of $500,000 or such
amount plus a whole  multiple of $100,000 in excess  thereof,  or, if less,  the
outstanding  principal  balance of the Revolving  Credit Loans or Term Loans, as
the case may be. After giving effect to any partial  prepayment  with respect to
Eurodollar  Advances  which were made (whether as the result of a borrowing or a
conversion)  to such  Borrower on the same date and which had the same  Interest
Period,  the outstanding  principal  balance of such  Eurodollar  Advances shall
exceed (subject to Section 3.3) $500,000 or such amount plus a whole multiple of
$100,000 in excess thereof.

     (b) Mandatory Prepayments of Revolving Credit Loans Relating to Termination
of the Commitments and Reductions of the Aggregate  Commitment Amount.  Upon the
termination of the Parent Commitments of all of the Lenders, Parent shall prepay
the outstanding principal balance of all Revolving Credit Loans and deposit into
the Parent Cash  Collateral  Account an amount  which would cause the balance on
deposit in the Parent Cash Collateral Account to equal or exceed an amount equal
to the Letter of Credit  Exposure of all  Lenders.  Upon each  reduction  of the
Aggregate  Parent  Commitment  Amount,  if the Aggregate  Parent Credit Exposure
would exceed the Aggregate Parent Commitment Amount as so reduced,  Parent shall
(unless the  Aggregate  Parent  Credit  Exposure  would not exceed the Aggregate
Parent  Commitment  Amount as so  reduced)  either  (A)  prepay  the  applicable
Revolving  Credit Loans,  or (B) make a deposit into the Parent Cash  Collateral
Account,  or both, so that the Aggregate Parent  Commitment Amount as so reduced
plus the balance on deposit in the Parent Cash  Collateral  Account would exceed
the Aggregate Parent Credit Exposure.  To the extent any mandatory  reduction of
the  Aggregate GP Canada  Credit  Exposure is required  pursuant to Section 2.4,
subject to Section  2.2(c),  such  reduction  shall be  effected  pursuant  to a
mandatory  prepayment of the Term Loans in an amount equal to the amount of such
reduction.

     (c) Mandatory Borrowing Base Prepayment of Revolving Loans; Contribution to
Parent Cash Collateral Account. If on any day prior to the Parent Maturity Date,
the Aggregate  Parent  Credit  Exposure  shall exceed the Borrowing  Base as set
forth on the most recent  Borrowing Base  Certificate or Updated  Borrowing Base
Certificate,  as the case may be, Parent shall, within ten (10) days of such day
(but in no event  later than the Parent  Maturity  Date),  prepay the  Revolving
Credit Loans in an amount equal to the lesser of such excess and the outstanding
principal  balance of the Revolving  Credit Loans,  provided,  however,  that if
after  giving  effect to such  prepayment  the  aggregate  principal  balance of
outstanding  Revolving  Credit  Loans is zero and the  Aggregate  Parent  Credit
Exposure still exceeds the Borrowing  Base,  Parent shall deposit as Parent Cash
Collateral  (into the Parent Cash  Collateral  Account) an amount  equal to such

<PAGE>

excess.  Until such excess has been prepaid and such deposit,  if required,  has
been made,  Parent shall not be entitled to borrow  additional  Revolving Credit
Loans or request the issuance of any Letter of Credit.

     (d) Mandatory Prepayment and Overadvance Reduction from Covered Events.


     (i) With  respect to each  Covered  Event by any Credit Party other than GP
Canada, (A) as long as the Overadvance Amount is greater than zero, the Required
Reduction  Amount  shall within one  Business  Day of the  consummation  of such
Covered Event be applied to reduce the  Overadvance  Amount with a corresponding
reduction in the Available Parent  Commitment Amount and to the extent that such
reduction in the  Overadvance  Amount  results in the  Aggregate  Parent  Credit
Exposure  exceeding the Borrowing Base as set forth in an Updated Borrowing Base
Certificate  (which  Borrowing Base shall be  recalculated to give effect to the
reduction in the Overadvance  Amount as hereinabove  provided and to give effect
to the removal from the  calculation  of such  Borrowing Base the asset that was
the subject of such  Covered  Event to the extent such asset was included in the
calculation of such Borrowing Base), mandatory prepayment of the Parent Facility
shall  be  required  as set  forth  in  Section  2.5(c),  (B) at  any  time  the
Overadvance  Amount is reduced to zero,  the  Required  Reduction  Amount  shall
within one Business Day of the  consummation of such Covered Event at the option
of Parent,  be (i)  deposited  as Parent  Cash  Collateral  in the  Parent  Cash
Collateral  Account  for all of the Parent  Obligations  (but in such event such
Parent Cash  Collateral  shall be excluded from the calculation of the Borrowing
Base), or (ii) subject to the  limitations set forth in Section 2.2(c),  applied
to reduce the  outstanding  balance of the Term Loans until the Term Loans shall
have been paid in full, at which time all remaining  Required  Reduction Amounts
shall be  deposited  as Parent Cash  Collateral  in the Parent  Cash  Collateral
Account  for all of the Parent  Obligations  (but in such event such Parent Cash
Collateral  shall be excluded from the calculation of the Borrowing  Base),  (C)
such Credit Party shall,  within one  Business Day of the  consummation  of each
such Covered Event, deliver to the Agent 100% of the non-cash consideration,  if
any, with respect to each such Covered Event to be held as additional collateral
for the  Obligations  and (D) if at the time of such Covered  Event a Default or
Event of Default has occurred and is  continuing,  100% of all Net Cash Proceeds
for such Covered  Event shall be applied as a mandatory  prepayment of Revolving
Credit  Loans  (which sums  required to be prepaid  pursuant to this  subsection
2.5(d)(i)(D)  may be  reborrowed  in  accordance  with  the  provisions  of this
Agreement at any time such Default or Event of Default is no longer continuing).

     (ii) Intentionally Omitted.

     (iii) On or before  September 15, 2000 and in any event within one Business
Day of the  receipt of the Life  Insurance  Proceeds  by Parent,  the greater of
$300,000 or 75% of the amount of such Life  Insurance  Proceeds shall be applied
by Parent to reduce the Overadvance Amount with a corresponding reduction in the

<PAGE>

Available Parent  Commitment Amount and to the extent that such reduction in the
Overadvance Amount results in the Aggregate Parent Credit Exposure exceeding the
Borrowing  Base as set forth in an Updated  Borrowing  Base  Certificate  (which
Borrowing  Base shall be  recalculated  to give effect to the  reduction  in the
Overadvance Amount as hereinabove provided),  mandatory prepayment of the Parent
Facility shall be required as set forth in Section 2.5(c).

     (e)  In  General.  Simultaneously  with  each  prepayment  of a  Loan,  the
applicable  Borrower  shall  prepay all accrued  interest on the amount  prepaid
through the date of prepayment and any amount required  pursuant to Section 3.10
hereto.  Provided no Default or Event of Default shall have occurred, the Parent
may specify the Loan to which any voluntary prepayment shall be applied.  Unless
otherwise specified by the applicable  Borrower,  each prepayment of Loans shall
first be applied to ABR Advances. If any prepayment or any other payment is made
in respect of any Eurodollar Advance, in whole or in part, prior to the last day
of the  applicable  Interest  Period,  each Borrower,  as applicable,  agrees to
indemnify the Lenders in accordance  with Section 3.5.  Prepayments  of the Term
Loans may not be  reborrowed,  shall  permanently  reduce the amount thereof and
shall be applied to the last maturing installments of such Term Loans in inverse
order of their respective maturities.

2.6  Use of Proceeds

     (a) Parent  agrees  that the  proceeds  of the  Revolving  Credit  Loans or
Letters of Credit shall be used solely,  directly or indirectly,  to (i) pay all
of the Fees of Parent due hereunder,  (ii) pay the reasonable out-of-pocket fees
and expenses  incurred by Parent in connection with the Loan Documents and (iii)
for Parent and the Subsidiary  Guarantors' working capital and general corporate
purposes not inconsistent with the provisions hereof.  Notwithstanding  anything
to the contrary  contained in any Loan  Document,  Parent agrees that no part of
the  proceeds  of any  Revolving  Credit  Loan or Letter of Credit will be used,
directly or  indirectly,  for a purpose  which  violates any law,  including the
provisions  of  Regulations  T, U or X of the Board of  Governors of the Federal
Reserve System, as amended.

     (b) GP Canada  agrees  that the  proceeds  of the Term Loans  shall be used
solely, directly or indirectly, to (i) finance in part the Learning Technologies
Acquisition  as it relates to assets located in Canada and to pay certain of the
fees and expenses in  connection  with such Learning  Technologies  Acquisition,
(ii)  pay  all of the  Fees  of GP  Canada  due  hereunder,  and  (iii)  pay the
reasonable  out-of-pocket  fees and expenses incurred by GP Canada in connection
with the Loan Documents.  Notwithstanding  anything to the contrary contained in
any Loan  Document,  GP Canada  agrees that no part of the  proceeds of any Term
Loan will be used, directly or indirectly, for a purpose which violates any law,
including the  provisions of  Regulations T, U or X of the Board of Governors of
the Federal Reserve System, as amended.

2.7  Letter of Credit Sub-Facility

     (a) Subject to the terms and conditions of this Agreement, the Issuing Bank
agrees,  in reliance on the  agreement of the other Lenders set forth in Section
2.8, to issue  standby  letters of credit (the  "Standby  Letters of Credit") or
commercial  (trade)  letters of credit  (the  "Trade  Letters  of  Credit"  and,
together with the Standby Letters of Credit, and the letters of credit currently
outstanding (the "Existing L/C's")and issued by the Issuing Bank for the account
of Parent or Physics described on Schedule 2.7 hereto,  the "Letters of Credit")
denominated  in Dollars during the Parent  Commitment  Period for the account of
Parent,  provided that, immediately after the issuance of each Letter of Credit,
(i) the Letter of Credit Exposure of all Lenders  (whether or not the conditions
for  drawing  under any  Letter of Credit  have or may be  satisfied)  would not
exceed the Letter of Credit  Commitment  Amount,  and (ii) the Aggregate  Parent
Credit  Exposure would not exceed the lesser of the Borrowing Base (as reflected
in an Updated  Borrowing Base  Certificate) and the Aggregate Parent  Commitment
Amount.  Each Standby Letter of Credit shall have an expiration date which shall
be not later than the earlier of (i) 365 days after the date of issuance thereof
or (ii) sixty days before the Parent  Maturity Date. Each Trade Letter of Credit
shall have an  expiration  date which shall be not later than the earlier of (i)
180 days after the date of issuance thereof  (although any such Letter of Credit
shall be renewable for an  additional  365 day period but in no event later than
the Parent Maturity Date) or (ii) sixty days before the Parent Maturity Date. No
Letter of Credit  shall be issued if the  Agent,  or any Lender by notice to the
Agent no later than 1:00 p.m. one Business  Day prior to the  requested  date of
issuance of such Letter of Credit,  shall have determined that any condition set
forth in Sections 5 or 6 has not been satisfied.

     (b) Each  Letter of Credit  shall be issued  for the  account  of Parent in
support of an  obligation  of Parent or a  Subsidiary  (other than GP Canada) in
favor of a  beneficiary  who has requested the issuance of such Letter of Credit
as a condition to a transaction  entered into in connection with the Parent,  or
Subsidiary's  ordinary course of business.  Parent shall give the Agent a Letter
of Credit Request for the issuance of each Letter of Credit by 11:00 a.m., three
Business  Days  prior to the  requested  date of  issuance.  No Letter of Credit
Request shall be honored  unless Parent shall have delivered to the Issuing Bank
(x) the Issuing Bank's standard Continuing  Agreement for Letters of Credit (the
"Reimbursement  Agreement")  and (y)  with  respect  to each  Letter  of  Credit
Request, the Issuing Bank's standard Letter of Credit application,  in each case
executed by an Authorized Signatory of Parent, and each Letter of Credit Request
shall  also  specify  (i) the  beneficiary  of such  Letter  of  Credit  and the
obligations  of Parent or of a  Subsidiary  Guarantor  in  respect of which such
Letter of Credit is to be issued,  (ii)  Parent'  proposal as to the  conditions
under  which  a  drawing  may be  made  under  such  Letter  of  Credit  and the
documentation to be required in respect thereof,  (iii) the maximum amount to be
available under such Letter of Credit,  and (iv) the requested dates of issuance
and expiration.  Upon receipt of such Letter of Credit Request from Parent,  the
Agent shall promptly notify the Issuing Bank and each other Lender thereof. Each
Letter of Credit shall be in form and substance  reasonably  satisfactory to the
Issuing Bank, with such provisions with respect to the conditions  under which a

<PAGE>

drawing may be made thereunder and the documentation required in respect of such
drawing as the  Issuing  Bank shall  reasonably  require.  Each Letter of Credit
shall be used solely for the purposes described therein. The Issuing Bank shall,
on the proposed date of issuance and subject to the terms and  conditions of the
Reimbursement Agreement and to the other terms and conditions of this Agreement,
issue the requested Letter of Credit.

     (c) Each  payment by the  Issuing  Bank of a draft  drawn under a Letter of
Credit shall give rise to an  obligation  on the part of Parent to reimburse the
Issuing Bank immediately for the amount thereof.

     (d)  Notwithstanding  anything to the contrary  contained  herein or in any
Reimbursement Agreement, to the extent that the terms of this Agreement shall be
inconsistent with the terms of such Reimbursement  Agreement,  the terms of this
Agreement shall govern.

     (e) It is expressly  agreed that as to the Existing L/C's,  notwithstanding
the fact that some of such L/C's may have been issued for the account of Physics
and were executed in connection with the Existing Bank Debt, and notwithstanding
the fact that such Existing  L/C's were issued in  connection  with the Existing
Bank Debt,  for purposes of this  Agreement,  Parent shall be obligated  for all
reimbursement and other obligations in connection  therewith as if such Existing
L/C's were issued pursuant to this Agreement (provided,  that, where Physics was
the account party with respect to such Existing L/C's, Physics shall nonetheless
remain  obligated  with  Parent,  on a joint and several  basis,  in  connection
therefor).  To the  extent the Agent or the  Issuing  Bank  determines  that the
provisions of any documents  executed in connection  with the Existing Bank Debt
would be  required  to effect  the  intent  of this  subparagraph  2.7(e),  such
documents and provisions (but only such documents and  provisions)  shall remain
in full  force  and  effect  as long as the  Agent  or the  Issuing  Bank  deems
necessary to effect the provisions of this subparagraph 2.7(e).

2.8  Letter of Credit Participation and Funding Commitments

     (a) Each Lender hereby unconditionally,  irrevocably and severally (and not
jointly)  for itself  only and without any notice to or the taking of any action
by such Lender, takes an undivided  participating interest in the obligations of
the Issuing Bank under and in connection with each Letter of Credit in an amount
equal to such Lender's Parent Commitment Percentage of the amount of such Letter
of  Credit.  Each  Lender  shall be liable to the  Issuing  Bank for its  Parent
Commitment  Percentage of the unreimbursed amount of any draft drawn and honored
under each  Letter of  Credit.  Each  Lender  shall also be liable for an amount
equal to the product of its Parent Commitment Percentage and any amounts paid by

<PAGE>

Parent  pursuant to Section  2.7(c) and 2.9 that are  subsequently  rescinded or
avoided,  or must otherwise be restored or returned.  Such liabilities  shall be
unconditional  and without  regard to the  occurrence of any Default or Event of
Default or the  compliance  by Parent or GP Canada  with any of its  obligations
under the Loan Documents.

     (b) The Issuing  Bank will  promptly  notify the Agent,  and the Agent will
promptly  notify each  Lender  (which  notice  shall be  promptly  confirmed  in
writing) of the date and the amount of any draft  presented  under any Letter of
Credit with respect to which full reimbursement of payment is not made by Parent
as provided in Section 2.7(c),  and forthwith upon receipt of such notice,  such
Lender  (other than the  Issuing  Bank in its  capacity as a Lender)  shall make
available to the Agent for the account of the Issuing Bank its Parent Commitment
Percentage of the amount of such  unreimbursed  draft at the office of the Agent
specified  in  Section  11.2,  in  lawful  money  of the  United  States  and in
immediately  available funds, before 4:00 p.m., on the day such notice was given
by the Agent,  if the relevant notice was given by the Agent at or prior to 1:00
p.m.,  on such day,  and before  12:00 noon,  on the next  Business  Day, if the
relevant  notice was given by the Agent after 1:00 p.m.,  on such day. The Agent
shall  distribute  the payments made by each such Lender (other than the Issuing
Bank in its capacity as a Lender) pursuant to the immediately preceding sentence
to the Issuing Bank  promptly  upon  receipt  thereof in like funds as received.
Each such Lender  shall  indemnify  and hold  harmless the Agent and the Issuing
Bank from and against any and all losses, liabilities (including liabilities for
penalties),  actions, suits,  judgments,  demands, costs and expenses (including
reasonable  attorneys' fees and expenses and an  administration  fee of not less
than $100 payable to the Issuing  Bank as the issuer of the  relevant  Letter of
Credit)  resulting  from any failure on the part of such  Lender to provide,  or
from any delay in providing,  the Agent with such Lender's Commitment Percentage
of the amount of any payment  made by the Issuing  Bank under a Letter of Credit
in accordance with this subsection (b) (except in respect of losses, liabilities
or other  obligations  suffered by the  Issuing  Bank  resulting  from the gross
negligence or willful misconduct of the Issuing Bank). If a Lender does not make
available to the Agent when due such Lender's  Parent  Commitment  Percentage of
any  unreimbursed  payment  made by the  Issuing  Bank  under a Letter of Credit
(other than payments made by the Issuing Bank by reason of its gross  negligence
or willful  misconduct),  such Lender  shall be required to pay  interest to the
Agent for the account of the Issuing  Bank on such  Lender's  Parent  Commitment
Percentage  of such payment at a rate of interest per annum equal to the Federal
Funds Rate for the first three days after the due date of such payment until the
date such  payment is received  by the Agent and the Federal  Funds Rate plus 2%
thereafter.  The Agent shall  distribute  such interest  payments to the Issuing
Bank upon receipt thereof in like funds as received.

     (c)  Whenever  the Agent is  reimbursed  by Parent,  for the account of the
Issuing Bank, for any payment under a Letter of Credit and such payment  relates
to an amount  previously  paid by a Lender in respect  of its Parent  Commitment
Percentage of the amount of such payment under such Letter of Credit,  the Agent
(or the  Issuing  Bank,  to the  extent  that the Agent has paid the same to the

<PAGE>

Issuing  Bank) will pay over such payment to such Lender (i) before 4:00 p.m. on
the day such payment from Parent is received,  if such payment is received at or
prior to 1:00 P.M. on such day, or (ii) before 12:00 noon on the next succeeding
Business  Day, if such payment from Parent is received  after 12:00 p.m. on such
day.

2.9  Absolute Obligation With Respect to Letter of Credit Payments

     (a) The  payment  of  drafts  under any  Letter of Credit  shall be made in
accordance  with the terms of such Letter of Credit and (i) the Uniform  Customs
and Practice for Documentary  Credits of the  International  Chamber of Commerce
No. 500, as adopted or amended from time to time,  in the case of Trade  Letters
of Credit  and (ii) the  International  Standby  Practices  1998 or most  recent
revision  thereof or  successor  thereto  which  shall be in effect from time to
time,  in the case of  Standby  Letters  of Credit.  The  Issuing  Bank shall be
entitled  to honor any drafts and accept any  documents  presented  to it by the
beneficiary of such Letter of Credit in accordance with the terms of such Letter
of Credit and  believed  by the Issuing  Bank in good faith to be  genuine.  The
Issuing  Bank  shall  not  have  any  duty  to  inquire  as to the  accuracy  or
authenticity  of any draft or other drawing  documents which may be presented to
it, but shall be  responsible  only to determine in  accordance  with  customary
commercial  practices  that the  documents  which are  required to be  presented
before  payment or  acceptance  of a draft  under any Letter of Credit have been
delivered  and that they  comply on their  face  with the  requirements  of that
Letter of Credit.

     (b)  Parent's  obligation  to  reimburse  the Agent for the  account of the
Issuing  Bank in  respect  of a Letter of Credit  for each  payment  under or in
respect of such Letter of Credit shall be absolute and  unconditional  under any
and all circumstances  and irrespective of any set-off,  counterclaim or defense
to payment  which  Parent may have or have had against the  beneficiary  of such
Letter of Credit,  the Agent,  the  Issuing  Bank,  as issuer of such  Letter of
Credit,  any Lender or any other  Person,  including  any  defense  based on the
failure of any  drawing to  conform to the terms of such  Letter of Credit,  its
lack of knowledge of the issuance of such Letter of Credit, any drawing document
proving  to be  forged,  fraudulent  or  invalid,  or  the  legality,  validity,
regularity or  enforceability  of such Letter of Credit;  provided,  that,  with
respect to any Letter of Credit,  the  foregoing  shall not  relieve the Issuing
Bank of any liability it may have to Parent for any actual damages  sustained by
Parent  arising  from a wrongful  payment  under such Letter of Credit made as a
result of the Issuing Bank's gross negligence or willful misconduct.

     (c) At any time when an Event of Default  exists,  upon  demand made by the
Agent  acting at the  request  of the  Required  Lenders,  the  Parent  shall be
obligated  forthwith to deposit in the Parent Cash Collateral  Account an amount
in  immediately  available  funds equal to the sum of (x) the aggregate  undrawn
face amount of the outstanding  Letters of Credit,  (y) the aggregate  amount of

<PAGE>

unpaid  drafts  drawn on all  Letters of Credit,  and (z) the  aggregate  unpaid
Reimbursement  Obligations  (after giving  effect to any Revolving  Credit Loans
made on such date to pay any such Reimbursement Obligations).

2.10 Payments

     (a) Each payment,  including each prepayment,  of principal and interest on
the Loans, of the Parent Commitment Fee, the Amendment Fee, the Letter of Credit
Commissions and of all of the other fees to be paid to the Agent and the Lenders
in connection  with this  Agreement  (the Parent  Commitment  Fee, the Letter of
Credit  Commissions,  the additional Letter of Credit fees and the Amendment Fee
and the Letter of Credit fronting fees referred to in Section  3.2(b),  together
with all of such other fees, being sometimes  hereinafter  collectively referred
to as the "Fees") shall be made by the  applicable  Borrower prior to 12:00 noon
on the date such  payment is due to the Agent for the account of the  applicable
Lenders at the Agent's office  specified in Section 11.2, in each case in lawful
money of the United States,  in immediately  available funds and without set-off
or  counterclaim.  As  between a  Borrower  and the  Lenders,  any  payment by a
Borrower  to the  Agent for the  account  of the  Lenders  shall be deemed to be
payment by such  Borrower to the Lenders.  The failure of a Borrower to make any
such  payment by such time shall not  constitute a Default,  provided  that such
payment is made on such due date,  but any such payment made after 12:00 noon on
such due date shall be deemed to have been made on the next Business Day for the
purpose of calculating  interest on amounts outstanding on the Loans. Subject to
Section  9.2(b),  promptly upon receipt by the Agent of each payment,  including
each prepayment, pursuant to this Section, the Agent shall remit such payment in
like funds as received as follows:  (a) in the case of the Parent Facility,  (i)
in the case of the Parent Commitment Fees and the Letter of Credit  Commissions,
to each Lender according to its Parent  Commitment  Percentage,  and (ii) in the
case of principal and interest on the Revolving Credit Loans, to each Lender pro
rata according to its Parent  Outstanding  Percentage of the amount of principal
or interest, as the case may be, which is then due and payable to the Lenders on
account of Revolving Credit Loans, (b) in the case of the GP Canada Facility, to
each Lender according to its GP Canada  Outstanding  Percentage of the amount of
principal  or  interest,  as the case may be,  which is due and  payable  to the
Lenders on account of Term Loans.

     (b) If any payment  hereunder,  under the Notes or under any  Reimbursement
Agreement shall be due and payable on a day which is not a Business Day, the due
date thereof (except as otherwise provided in the definition of Interest Period)
shall be extended to the next  Business Day and (except with respect to payments
in  respect  of the Fees)  interest  shall be  payable  at the  applicable  rate
specified  herein  during such  extension,  provided,  however that if such next
Business  Day is after (i) the Parent  Maturity  Date in the case of payments in
connection with the Parent Facility,  or (ii) the GP Canada Maturity Date in the
case of payments in  connection  with the GP Canada  Facility,  any such payment
shall be due on the immediately  preceding Business Day. However, in the case of
the GP Canada  Facility,  if the  immediately  preceding  Business Day is not at

<PAGE>

least five years and one day after the GP Canada  Borrowing Date, the payment(s)
shall be due and payable on the next  Business  Day which is at least five years
and one day after the GP Canada Borrowing Date.

2.11 Cash Collateral Accounts

     (a) At, or at any time before,  the time Parent shall be required to make a
deposit into the "Parent Cash Collateral Account" defined below, the Agent shall
establish and maintain at its offices at 1185 Avenue of the Americas,  New York,
New York in the name of the Parent but under the sole  dominion  and  control of
the Agent,  a separate cash  collateral  account  designated  as "GP  Strategies
Corporation Cash Collateral  Account"  (collectively the "Parent Cash Collateral
Account").  Parent  may from  time to time  make one or more  deposits  into the
Parent  Cash  Collateral  Account.  Parent  hereby  pledges to the Agent for its
benefit,  the  benefit  of the  Issuing  Bank  and the pro rata  benefit  of the
Lenders,  a Lien on and security interest in the Parent Cash Collateral  Account
and all sums at any time and from time to time on deposit  therein  (the  Parent
Cash  Collateral  Account,  together  with all sums on  deposit  therein,  being
sometimes hereinafter collectively referred to as the "Parent Cash Collateral"),
as first priority  collateral  security for the prompt payment in full when due,
whether at stated  maturity,  by  acceleration  or  otherwise  of all the Parent
Obligations.  Parent  agrees  that  at any  time  and  from  time to time at its
expense,  it  will  promptly  execute  and  deliver  to the  Agent  any  further
instruments and documents,  and take any further actions,  that may be necessary
or that the Agent may  reasonably  request,  in order to perfect and protect any
first priority security interest granted or purported to be granted hereby or to
enable the Agent to exercise and enforce its rights and remedies  hereunder with
respect to any Parent Cash  Collateral.  Parent agrees that it will not (i) sell
or  otherwise  dispose of any of the Parent Cash  Collateral,  or (ii) create or
permit to exist any Lien upon any of the  Parent  Cash  Collateral,  except  for
Permitted Liens. Parent hereby authorizes the Agent, promptly after each drawing
under any  Letter of Credit  shall  become due and  payable  and at any time any
other Parent  Obligations  shall be due and owing,  to apply any and all cash on
deposit in the Parent Cash Collateral  Account towards the  reimbursement of the
Issuing  Bank for all sums paid in respect of such  drawing,  and all other such
Parent Obligations which shall then be due and owing.

     (b) The Agent shall establish and maintain at its offices at 1185 Avenue of
the  Americas,  New York,  New York in the name of GP Canada  but under the sole
dominion and control of the Agent, a separate cash collateral account designated
as "General Canada Physics Ltd. Cash Collateral  Account"  (collectively the "GP
Canada Cash Collateral Account").  GP Canada may from time to time, but shall in
no event be  required  to,  make one or more  deposits  into the GP Canada  Cash
Collateral Account.  GP Canada hereby pledges to the Agent for its benefit,  the
benefit of the Issuing Bank and the pro rata  benefit of the Lenders,  a Lien on
and security  interest in the GP Canada Cash Collateral  Account and all sums at
any time and from time to time on deposit therein (the GP Canada Cash Collateral

<PAGE>

Account,  together with all sums on deposit therein, being sometimes hereinafter
collectively referred to as the "GP Canada Cash Collateral"),  as first priority
collateral  security for the prompt payment in full when due,  whether at stated
maturity,  by  acceleration  or otherwise of all the GP Canada  Obligations.  GP
Canada  agrees  that at any time and from time to time at its  expense,  it will
promptly execute and deliver to the Agent any further instruments and documents,
and take any  further  actions,  that may be  necessary  or that the  Agent  may
reasonably  request, in order to perfect and protect any first priority security
interest  granted or  purported  to be granted  hereby or to enable the Agent to
exercise  and enforce its rights and remedies  hereunder  with respect to any GP
Canada Cash Collateral.  GP Canada agrees that it will not (i) sell or otherwise
dispose of any of the GP Canada  Cash  Collateral,  or (ii)  create or permit to
exist any Lien upon any of the GP Canada Cash  Collateral,  except for Permitted
Liens.  GP  Canada  hereby  authorizes  the  Agent,  at any time  any GP  Canada
Obligations  shall be required to be paid,  to apply any and all cash on deposit
in the GP Canada Cash Collateral  Account towards all such GP Canada Obligations
which shall then be due and owing.

2.12 Defaulting Lender

     (a)  Notwithstanding  anything  to the  contrary  herein,  in the event any
Lender (x) has refused (which refusal constitutes a breach by such Lender of its
obligations  under this  Agreement) to make available its portion of any Loan or
(y) notifies  either the Agent or any  Borrower  that it does not intend to make
available  its portion of any Loan (if the actual  refusal  would  constitute  a
breach by such Lender of its obligations  under this Agreement)  (each a "Lender
Default"),  all rights and  obligations  hereunder of such Lender (a "Defaulting
Lender")  as to which a Lender  Default  is in effect  and of the other  parties
hereto shall be modified to the extent of the express provisions of this Section
2.12 while such Lender Default remains in effect.

     (b) Loans  shall be incurred  pro rata from  Lenders  (the  "Non-Defaulting
Lenders") which are not Defaulting Lenders based on their respective  Commitment
Percentages  with respect to such Loans,  and no  Commitment  Percentage  of any
Lender or any pro rata share of any Loans  required to be advanced by any Lender
shall be  increased  as a result of such  Lender  Default.  Amounts  received in
respect  of  principal  of any type of Loans  shall be  applied  to  reduce  the
applicable Loans of each Lender pro rata based on (i) with respect to the Parent
Facility,  the Parent Outstanding Percentage at the time of such application and
(ii) with respect to the GP Canada Facility,  subject to Section 2.2(c),  the GP
Canada Outstanding  Percentage at the time of such application;  provided,  that
such amount shall not be applied to any Loans of a Defaulting Lender at any time
when,  and  to  the  extent  that,   the  aggregate   amount  of  Loans  of  any
Non-Defaulting Lender exceeds such Non-Defaulting Lender's Commitment Percentage
of all Loans then outstanding.

     (c) A Defaulting  Lender shall not be entitled to give  instructions to the
Agent or to approve,  disapprove,  consent to or vote on any matters relating to
this Agreement and the other Loan Documents.  All amendments,  waivers and other

<PAGE>

modifications of this Agreement and the other Loan Documents may be made without
regard to a Defaulting  Lender and, for purposes of the  definition of "Required
Lenders", a Defaulting Lender shall be deemed not to be a Lender and not to have
Loans outstanding.

     (d) Other than as expressly set forth in this Section 2.12,  the rights and
obligations  of  a  Defaulting  Lender  (including,   without  limitation,   the
obligation  to indemnify  the Agent) and the other  parties  hereto shall remain
unchanged.  To the extent the Borrower  incurs any costs  directly  related to a
repayment  under Section  2.3(c),  such  Defaulting  Lender shall reimburse such
Borrower  for all such costs.  Nothing in this  Section  2.12 shall be deemed to
release any Defaulting  Lender from its obligations under this Agreement and the
other Loan Documents, shall alter such obligations, shall operate as a waiver of
any default by such Defaulting Lender  hereunder,  or shall prejudice any rights
which any  Borrower,  the Agent or any Lender may have  against  any  Defaulting
Lender as a result of any default of such Defaulting Lender hereunder.

     (e) In the event a Defaulting Lender cures to the satisfaction of the Agent
the breach which caused a Lender to become a Defaulting Lender,  such Defaulting
Lender shall no longer be a  Defaulting  Lender and shall be treated as a Lender
under this Agreement.

2.13 Recordation of Mortgages.

     The Agent shall not record the Mortgage on the MXL Property  unless the MXL
Sale/Leaseback is not consummated on or before October 15, 2000 on the terms set
forth in the Letter of Intent;  provided, that, if the MXL Sale/Leaseback is not
so  consummated  on or before  October 15, 2000,  the Agent shall promptly after
such date record the  Mortgage on the MXL  Property  and all costs and  expenses
thereof  or  incurred  by the Agent in  connection  therewith  shall be borne by
Parent.  The Mortgage on the Pawling Property and the Reservoir  Property may be
recorded  on or any time  after  the date on which  the  originals  thereof  are
furnished  to the Agent and all costs and  expenses  thereof or  incurred by the
Agent in connection therewith shall be borne by Parent.

3.       INTEREST, FEES, YIELD PROTECTIONS, ETC.

3.1      Interest Rate and Payment Dates

     (a) Prior to Maturity.  Except as otherwise  provided in Section 3.1(b) and
3.1(c), prior to maturity,  the Revolving Credit Loans and Term Loans shall bear
interest on the outstanding principal balance thereof at the applicable interest
rate or rates per annum set forth below:


<PAGE>

             ADVANCES RATE

        Each Parent ABR Advance           Alternate Base Rate plus
                                          the Applicable Margin.

        Each GP Canada ABR Advance        Alternate Base Rate plus 1.25%.

        Each Parent Eurodollar            Eurodollar Rate for the
         Advance                          applicable Interest Period plus the
                                          Applicable Margin.

        Each GP Canada Eurodollar         Eurodollar Rate for the
         Advance                        applicable Interest Period plus 2.75%.

     (b) Late Charges.  Upon the  occurrence  and during the  continuance of an
Event of Default, the unpaid principal balance of the Revolving Credit Loans and
Term Loans shall bear interest,  payable on demand, at a rate per annum (whether
before or after the entry of a judgment thereon) equal to 2% plus the rate which
would   otherwise  be  applicable   under  Section   3.1(a),   and  any  overdue
Reimbursement  Obligation,  interest  or other  amount  payable  under  the Loan
Documents shall bear interest,  payable on demand,  at a rate per annum (whether
before or after the entry of a judgment  thereon)  equal to the  Alternate  Base
Rate plus the Applicable Margin applicable to ABR Advances plus 2%.

     (c) Highest  Lawful Rate. At no time shall the interest rate payable on the
Loans of any Lender,  together with the Fees and all other amounts payable under
the Loan  Documents  to such  Lender,  to the extent the same are  construed  to
constitute  interest,  exceed the Highest Lawful Rate applicable to such Lender.
If with respect to any Lender for any period during the term of this  Agreement,
any amount paid to such Lender under the Loan Documents,  to the extent the same
shall  (but for the  provisions  of this  Section)  constitute  or be  deemed to
constitute  interest,  would exceed the maximum amount of interest  permitted by
the Highest  Lawful Rate  applicable  to such  Lender  during such period  (such
amount  being  hereinafter  referred to as an  "Unqualified  Amount"),  then (i)
subject to Section 2.2(c),  such Unqualified Amount shall be applied or shall be
deemed to have been  applied as a prepayment  of the Loans of such  Lender,  and
(ii) if in any subsequent period during the term of this Agreement,  all amounts
payable under the Loan  Documents to such Lender in respect of such period which
constitute  or shall be deemed  to  constitute  interest  shall be less than the
maximum amount of interest  permitted by the Highest  Lawful Rate  applicable to
such Lender during such period,  then the applicable  Borrower shall pay to such
Lender, as interest and not in repayment of principal, in respect of such period
an amount (each a "Compensatory  Interest Payment") equal to the lesser of (x) a
sum which,  when added to all such  amounts,  would equal the maximum  amount of
interest  permitted by the Highest Lawful Rate  applicable to such Lender during
such period,  and (y) an amount equal to the  Unqualified  Amount less all other
Compensatory Interest Payments made in respect thereof.


<PAGE>

     (d) Interest Act Compliance.  For purpose of the Interest Act (Canada), (i)
whenever any interest or fee under this  Agreement  is  calculated  using a rate
based on a year of 360 days or 365 days, as the case may be, the rate determined
pursuant to such calculation, when expressed as an annual rate, is equivalent to
(x) the applicable rate based on a year of 360 days or 365 days, as the case may
be, (y)  multiplied  by the actual  number of days in the calendar year in which
the period for which such interest or fee is payable (or  compounded)  ends, and
(z)  divided by 360 or 365,  as the case may be,  (ii) the  principle  of deemed
reinvestment of interest does not apply to any interest  calculation  under this
Agreement,  and (iii) the rates of interest  stipulated  in this  Agreement  are
intended to be nominal rates and not effective rates or yields.

     (e) In General.  Interest on ABR Advances and on Eurodollar  Advances shall
be  calculated  on the basis of a 360-day  year,  in each  case,  for the actual
number of days elapsed. Except as otherwise provided in Section 3.1(b), interest
shall be payable in arrears on each Interest  Payment Date and upon each payment
(including  prepayment)  of the Loans.  Any change in the  interest  rate on the
Loans resulting from a change in the Alternate Base Rate or reserve requirements
shall  become  effective  as of the opening of business on the day on which such
change shall become effective.  The Agent shall, as soon as practicable,  notify
each Borrower and the Lenders of the effective  date and the amount of each such
change in the Fleet Rate,  but any failure to so notify  shall not in any manner
affect the  obligation  of Parent and GP Canada to pay  interest on the Loans in
the amounts and on the dates required.  Each determination of the Alternate Base
Rate or a  Eurodollar  Rate by the Agent  pursuant  to this  Agreement  shall be
conclusive  and  binding on all  parties  hereto  absent  manifest  error.  Each
Borrower  acknowledges  that to the extent  interest  payable on ABR Advances is
based on the  Fleet  Rate,  such  rate is only one of the  bases  for  computing
interest on loans made by the  Lenders,  and by basing  interest  payable on ABR
Advances on the Fleet Rate,  the Lenders have not  committed to charge,  and the
Borrowers  have not in any way bargained  for,  interest based on a lower or the
lowest  rate at which the  Lenders  may now or in the future make loans to other
borrowers.

     (f) Further Adjustments to Applicable Margins and Applicable Percentages.

     (i) If at the end of any  fiscal  quarter  of Parent  there is not  Minimum
Excess  Availability,  the Applicable  Margin for Parent ABR Advances and Parent
Eurodollar  Advances and the  Applicable Fee Percentage for the Parent Letter of
Credit  Commissions  for  Standby  Letters  of  Credit  shall  each  immediately
increase,  on a cumulative  basis, by .25% from the rate that was theretofore in
effect, provided, that, if at the end of any subsequent fiscal quarter of Parent
there is  Minimum  Excess  Availability,  the  Applicable  Margin for Parent ABR
Advances and Parent  Eurodollar  Advances and the  Applicable Fee Percentage for
Letter  of  Credit   Commissions  for  Standby  Letters  of  Credit  shall  each
immediately  decrease  to  those  initially  provided  in the  table  under  the
definitions of "Applicable Fee Percentage" and "Applicable  Margin", as the case
may be, subject to further increase (in the manner  heretofore  provided) at the
end of each  fiscal  quarter  of Parent  thereafter  if there is not  maintained
Minimum Excess Availability.


<PAGE>

     (ii) To the extent that there is Prompt  Compliance,  the Applicable Margin
for Parent ABR Advances and Parent  Eurodollar  Advances and the  Applicable Fee
Percentage for Letter of Credit  Commissions for Standby Letters of Credit shall
each  decrease  by .25% from those  initially  set forth in the table  under the
definitions  of "Applicable  Fee  Percentage"  and  "Applicable  Margin",  which
Applicable  Margins and Applicable Fee Percentage shall be maintained as long as
there remains  Minimum  Excess  Availability  (when and as required);  provided,
that,  if at any time Minimum  Excess  Availability  is not so  maintained,  the
Applicable Margin for Parent ABR Advances and Parent Eurodollar Advances and the
Applicable Fee Percentage for Letter of Credit  Commissions  for Standby Letters
of Credit shall each be immediately  increased to .25% above those initially set
forth in the table under the  definitions of  "Applicable  Fee  Percentage"  and
"Applicable  Margin",  as the  case  may be,  subject  to  further  increase  or
decrease, as the case may be, in the manner provided under Section 3.1(f)(i), at
the end of each fiscal  quarter of Parent  thereafter as a result of adjustments
due to the Minimum  Excess  Availability  requirements  set forth in  subsection
3.1(f)(i).

3.2  Fees

     (a) Parent  Commitment  Fee.  Parent  agrees to pay to the  Agent,  for the
account of the  Lenders  in  accordance  with each  Lender's  Parent  Commitment
Percentage,  a fee (the "Parent  Commitment Fee"),  during the Parent Commitment
Period,  at a rate per  annum  equal to the  Applicable  Fee  Percentage  on the
average daily Adjusted Available Parent Commitment Amount. The Parent Commitment
Fee shall be payable  quarterly in arrears on the last day of each March,  June,
September and December of each year,  commencing on the first such day following
the Effective  Date,  and ending on the date that the Parent  Commitments  shall
expire or otherwise terminate.  The Parent Commitment Fee shall be calculated on
the basis of a 360 day year for the actual number of days elapsed.

     (b) Letter of Credit Commissions; Fronting Fees and Additional Fees. Parent
agrees to pay to (i) the Agent,  for the  account of the  Lenders in  accordance
with each Lender's Parent  Commitment  Percentage,  commissions  (the "Letter of
Credit  Commissions")  with respect to the Letters of Credit for the period from
and  including  the  date of  issuance  of each  thereof  to and  including  the
expiration  date  thereof,  at a rate per  annum  equal to (x) with  respect  to
Standby Letters of Credit,  the Applicable Fee Percentage  applicable thereto in
effect on the date of issuance thereof, and (y) with respect to Trade Letters of
Credit the Applicable Fee  Percentage  applicable  thereto (but in no event less
than $75) in effect on the date of issuance thereof, in each case on the average
daily maximum  amount  available  under any  contingency  to be drawn under such
Letter of Credit, and (ii) to the Issuing Bank for its own account, (x) a Letter
of Credit  fronting fee in an amount  equal to the original  face amount of each
Letter of Credit  multiplied  by one  eighth of one  percent  (1/8%)  per annum,
payable upon  issuance of each such Letter of Credit,  and (y) its standard fees
and charges  customarily  charged to customers similar to Parent with respect to
any Letter of Credit.  The Letter of Credit  Commissions shall be (A) calculated

<PAGE>

on the basis of a 360-day  year for the actual  number of days  elapsed  and (B)
payable quarterly in arrears on the last day of each March, June,  September and
December of each year and on the Parent Maturity Date.

     (c) Agent's Fees. The Borrowers, on a joint and several basis, agree to pay
to the Agent,  for its own  account,  such other fees as have been  agreed to in
writing by one or more Borrower and the Agent.

     (d) Amendment  Fee.  Parent agrees to pay (or have paid) to the Agent,  for
the account of the Lenders in accordance  with each Lender's  Parent  Commitment
Percentage,  a fee (the  "Amendment  Fee") equal to .25% of each Lender's Parent
Commitment  Amount plus .25% of each Lender's Term Loan then  outstanding on the
Closing Date.

3.3  Conversions

     (a) A Borrower  may elect  from time to time to convert  one or more of its
Eurodollar  Advances to ABR  Advances by giving the Agent at least one  Business
Day's prior  irrevocable  notice of such election,  specifying the Advance to be
converted,  provided, that any such conversion of Eurodollar Advances shall only
be made on the last day of the Interest Period applicable  thereto. In addition,
a  Borrower  may elect  from time to time to  convert  its (i) ABR  Advances  to
Eurodollar  Advances and (ii) Eurodollar  Advances to new Eurodollar Advances by
selecting a new Interest  Period  therefor,  in each case by giving the Agent at
least three Business  Days' prior  irrevocable  notice of such election,  in the
case of a conversion  to  Eurodollar  Advances,  specifying  the amount to be so
converted and the initial  Interest Period relating  thereto,  provided that any
such  conversion of ABR Advances to Eurodollar  Advances shall only be made on a
Business Day and any such  conversion of Eurodollar  Advances to new  Eurodollar
Advances shall only be made on the last day of the Interest Period applicable to
the  Eurodollar  Advances  which  are to be  converted  to such  new  Eurodollar
Advances.  Each  such  notice  shall be  irrevocable  and  shall be given by the
delivery by telecopy of a Notice of Conversion  (confirmed promptly,  and in any
event within five  Business  Days),  by the delivery to the Agent of a Notice of
Conversion manually signed by the applicable Borrower.  The Agent shall promptly
provide the applicable  Lenders with notice of each such election.  Advances may
be  converted  pursuant to this Section in whole or in part,  provided  that the
amount to be converted by a Borrower to each Eurodollar Advance, when aggregated
with  any  Eurodollar  Advance  to be  made  to such  Borrower  on such  date in
accordance  with Section 2.3 and having the same  Interest  Period as such first
Eurodollar  Advance,  shall equal no less than  $1,000,000 or such amount plus a
whole multiple of $100,000 in excess thereof.

     (b)  Notwithstanding  anything in this Agreement to the contrary,  upon the
occurrence and during the  continuance  of a Default or an Event of Default,  no
Borrower  shall have any right to elect to convert any existing ABR Advance to a

<PAGE>

new Eurodollar  Advance or to convert any existing  Eurodollar  Advance to a new
Eurodollar  Advance.  In such event,  all ABR  Advances  shall be  automatically
continued as ABR Advances and all  Eurodollar  Advances  shall be  automatically
converted to ABR Advances on the last day of the Interest  Period  applicable to
such Eurodollar Advance.

     (c) Each conversion shall be effected by each Lender by reflecting the Type
of Loan from the Advance  being  converted to the new ABR Advance or  Eurodollar
Advance, as the case may be, (it being understood that any such conversion shall
not  constitute a borrowing.  Each  conversion  of an Advance does not reflect a
repayment  of  the  converted  Advance  or  an  additional   borrowing,   but  a
continuation of the original obligation in full force and effect.

3.4  Concerning Interest Periods

     Notwithstanding any other provision of any Loan Document:

     (a) If the  applicable  Borrower  shall have  failed to elect a  Eurodollar
Advance  under  Section 2.3 or 3.3, as the case may be, in  connection  with any
borrowing of new Loans or expiration  of an Interest  Period with respect to any
existing Eurodollar  Advance,  the amount of the Loans subject to such borrowing
or such existing Eurodollar Advance shall thereafter be a Eurodollar Advance for
one or more  Interest  Periods of one month  until such time,  if any,  as a new
Eurodollar Advance shall have been elected pursuant to Section 3.3.

     (b) No Interest  Period  selected in respect of the borrowing or conversion
of any Eurodollar  Advance shall end after the Parent  Maturity Date in the case
of the  Parent  Facility  or the GP Canada  Maturity  Date in the case of the GP
Canada Facility.

     (c)  The  Borrowers  shall  not be  permitted  to  have  more  than  twenty
Eurodollar  Advances  outstanding  at any one time,  it being  agreed  that each
borrowing of a Eurodollar  Advance pursuant to a single Borrowing  Request shall
constitute the making of one  Eurodollar  Advance for the purpose of calculating
such limitation.

3.5  Indemnification for Loss

     Notwithstanding  anything  contained herein to the contrary,  if a Borrower
shall fail to borrow or convert on a Borrowing Date or Conversion  Date after it
shall have given  notice to do so in which it shall have  requested a Eurodollar
Advance,  or if a Eurodollar Advance shall be terminated for any reason prior to
the  last  day of the  Interest  Period  applicable  thereto,  or  if,  while  a
Eurodollar  Advance  is  outstanding,   any  repayment  or  prepayment  of  such
Eurodollar Advance is made for any reason (including as a result of acceleration
or illegality)  on a date which is prior to the last day of the Interest  Period
applicable thereto,  such Borrower agrees to indemnify each Lender against,  and
to pay on demand directly to such Lender,  any loss or expense  suffered by such
Lender as a result of such failure to borrow or convert, termination,  repayment
or prepayment, including an amount, if greater than zero, equal to:

<PAGE>

                  A  x  (B-C)  x   D
                                  360
where:

     "A" equals such Lender's pro rata share of the Affected Principal Amount;

     "B" equals the Eurodollar Rate (expressed as a decimal), applicable to such
Eurodollar Advances;

     "C" equals the Eurodollar  Rate  (expressed as a decimal),  in effect on or
about the first day of the applicable  Remaining  Interest Period,  based on the
applicable  rates offered or bid, as the case may be, on or about such date, for
deposits in an amount equal approximately to such Lender's pro rata share of the
Affected  Principal  Amount with an Interest Period equal  approximately  to the
applicable Remaining Interest Period, as determined by such Lender;

     "D"  equals  the  number  of days from and  including  the first day of the
applicable  Remaining  Interest  Period  to but  excluding  the last day of such
Remaining Interest Period;

and any other  out-of-pocket loss or expense (including any internal  processing
charge customarily charged by such Lender) suffered by such Lender in connection
with such  Eurodollar  Advance,  including in liquidating or employing  deposits
acquired to fund or maintain  the funding of its pro rata share of the  Affected
Principal  Amount,  or  redeploying  funds  prepaid or repaid,  in amounts which
correspond  to its  pro  rata  share  of the  Affected  Principal  Amount.  Each
determination  by the  Agent  or a  Lender  pursuant  to this  Section  shall be
conclusive and binding on each Borrower absent manifest error.

3.6   Capital Adequacy

     If the amount of capital  required  or  expected  to be  maintained  by any
Lender or the  Issuing  Bank or any  Person  directly  or  indirectly  owning or
controlling such Lender or the Issuing Bank (each a "Control Person"),  shall be
affected by the occurrence of a Regulatory Change and such Lender or the Issuing
Bank shall have determined  that such  Regulatory  Change shall have had or will
thereafter  have the effect of reducing (i) the rate of return on such Lender's,
the Issuing Bank's or such Control Person's capital,  or (ii) the asset value to
such Lender,  the Issuing Bank or such Control  Person of the  Revolving  Credit
Loans made or maintained by such Lender, or of the Reimbursement  Obligations or
any participation  therein, in any case to a level below that which such Lender,
the Issuing Bank or such Control Person could have achieved or would  thereafter
be able to achieve but for such  Regulatory  Change  (after  taking into account
such Lender's,  the Issuing Bank's or such Control Person's  policies  regarding
capital  adequacy) by an amount  deemed by such Lender or the Issuing Bank to be
material to such Lender,  the Issuing Bank or Control Person,  then,  within ten

<PAGE>

days after demand by such Lender or the Issuing Bank, each Borrower shall pay to
such Lender,  the Issuing Bank or such Control Person such additional  amount or
amounts as shall be sufficient to  compensate  such Lender,  the Issuing Bank or
such Control Person, as the case may be, for such reduction.

3.7   Reimbursement for Increased Costs

     If any  Lender,  the  Agent or the  Issuing  Bank  shall  determine  that a
Regulatory Change:

     (a) does or shall  subject  it to any  Taxes  of any kind  whatsoever  with
respect to any Eurodollar  Advances or its  obligations  under this Agreement to
make Eurodollar  Advances,  or change the basis of taxation of payments to it of
principal,  interest or any other  amount  payable  hereunder  in respect of its
Eurodollar Advances, or impose on the Agent, the Issuing Bank or such Lender any
other condition  regarding the Letters of Credit including any Taxes required to
be withheld from any amounts  payable under the Loan  Documents  (except for, in
each  case,  imposition  of, or change in the rate of, Tax on the Income of such
Lender); or

     (b) does or shall impose,  modify or make  applicable any reserve,  special
deposit,  compulsory  loan,  assessment,  increased cost or similar  requirement
against assets held by, or deposits of, or advances or loans by, or other credit
extended by, or any other  acquisition of funds by, any office of such Lender in
respect  of its  Eurodollar  Advances  which is not  otherwise  included  in the
determination  of a Eurodollar  Rate, or against any Letters of Credit issued by
the Issuing Bank or participated in by any Lender;  and the result of any of the
foregoing is to increase the cost to such Lender of making, renewing, converting
or maintaining its Eurodollar Advances or its commitment to make such Eurodollar
Advances,  or to reduce  any  amount  receivable  hereunder  in  respect  of its
Eurodollar  Advances,  or to increase the cost to the Issuing Bank of issuing or
maintaining  the  Letters of Credit or the cost to any  Lender of  participating
therein  or the  cost  to the  Agent  or the  Issuing  Bank  of  performing  its
respective  functions hereunder with respect to the Letters of Credit,  then, in
any such case,  each Borrower shall pay such Lender,  the Agent,  or the Issuing
Bank, as the case may be, within ten days after demand therefor, such additional
amounts as is  sufficient  to  compensate  such Lender,  the Issuing Bank or the
Agent,  as the case may be, for such additional cost or reduction in such amount
receivable which such Lender, the Issuing Bank or the Agent, as the case may be,
deems to be material  as  determined  by such  Lender,  the Issuing  Bank or the
Agent, as the case may be; provided, however, that nothing in this Section shall
require the Borrowers to indemnify the Lenders,  the Agent, or the Issuing Bank,
as the case may be, with respect to  withholding  Taxes for which the  Borrowers
have no obligation under Section 3.10. No failure by any Lender or the Agent, or
the Issuing  Bank to demand,  and no delay in  demanding,  compensation  for any
increased  cost  shall   constitute  a  waiver  of  its  right  to  demand  such
compensation  at any time. A statement  setting  forth the  calculations  of any
additional  amounts payable pursuant to this Section submitted by a Lender,  the
Agent or the Issuing Bank, as the case may be, to a Borrower shall be conclusive
absent manifest error.


<PAGE>

3.8  Illegality of Funding

     Notwithstanding  any other provision hereof, if any Lender shall reasonably
determine that any law, regulation,  treaty or directive,  or any change therein
or in the interpretation or application thereof, shall make it unlawful for such
Lender to make or  maintain  any  Eurodollar  Advance  as  contemplated  by this
Agreement,  such  Lender  shall  promptly  notify  each  Borrower  and the Agent
thereof,  and (i) the commitment of such Lender to make such Eurodollar Advances
or convert ABR Advances to  Eurodollar  Advances  shall  forthwith be suspended,
(ii) such Lender shall fund its portion of each requested  Eurodollar Advance as
an ABR Advance and (iii) such Lender's Loans then outstanding as such Eurodollar
Advances,  if any, shall be converted  automatically to ABR Advances on the last
day of the then current  Interest Period  applicable  thereto or at such earlier
time as may be required by law. If the  commitment of any Lender with respect to
Eurodollar  Advances is suspended pursuant to this Section and such Lender shall
have obtained  actual  knowledge  that it is once again legal for such Lender to
make or maintain  Eurodollar  Advances,  such Lender shall  promptly  notify the
Agent and each Borrower  thereof and, upon receipt of such notice by each of the
Agent and each Borrower, such Lender's commitment to make or maintain Eurodollar
Advances shall be reinstated.

3.9  Substituted Interest Rate

     In the event that (i) the Agent shall have determined (which  determination
shall  be  conclusive  and  binding  upon  each  Borrower)  that  by  reason  of
circumstances  affecting the  interbank  eurodollar  market either  adequate and
reasonable  means do not exist for  ascertaining  the Eurodollar Rate applicable
pursuant to Section 3.1 or (ii) the  Required  Lenders  shall have  notified the
Agent that they have  determined  (which  determination  shall be conclusive and
binding  on  each  Borrower)  that  the  applicable  Eurodollar  Rate  will  not
adequately and fairly reflect the cost to such Lenders of maintaining or funding
loans  bearing  interest  based on such  Eurodollar  Rate,  with  respect to any
portion  of the  Loans  that a  Borrower  has  requested  be made as  Eurodollar
Advances or Eurodollar  Advances that will result from the requested  conversion
of any  portion  of the  Advances  into  or of  Eurodollar  Advances  (each,  an
"Affected  Advance"),  the Agent shall  promptly  notify each  Borrower  and the
Lenders (by telephone or otherwise, to be promptly confirmed in writing) of such
determination,  on or,  to  the  extent  practicable,  prior  to  the  requested
Borrowing Date or Conversion Date for such Affected Advances. If the Agent shall
give such notice,  (a) any Affected Advances shall be made as ABR Advances,  (b)
the  Advances  (or any  portion  thereof)  that were to have been  converted  to

<PAGE>

Affected  Advances  shall be converted  to ABR Advances and (c) any  outstanding
Affected  Advances  shall be  converted,  on the  last  day of the then  current
Interest Period with respect  thereto,  to ABR Advances.  Until any notice under
clauses (i) or (ii),  as the case may be, of this Section has been  withdrawn by
the Agent (by notice to each Borrower  promptly upon either (x) the Agent having
determined that such circumstances  affecting the interbank eurodollar market no
longer exist and that adequate and reasonable means do exist for determining the
Eurodollar Rate pursuant to Section 3.1 or (y) the Agent having been notified by
such Required  Lenders that  circumstances no longer render the Advances (or any
portion thereof)  Affected  Advances,  no further  Eurodollar  Advances shall be
required to be made by the  Lenders,  nor shall any  Borrower  have the right to
convert all or any portion of the Loans to or as Eurodollar Advances.

3.10 Taxes

     (a) Payments to be Free and Clear.  Except as otherwise  expressly required
by applicable law, all payments by each Credit Party under the Loan Documents to
or for the  account of the Agent,  the  Issuing  Bank or any  Lender  (each,  an
"Indemnified  Tax  Person")  shall be made free and clear of,  and  without  any
deduction  or  withholding  for or on account  of, any and all present or future
income,  stamp or other  taxes,  levies,  imposts,  duties,  fees,  assessments,
deductions,  withholdings, or other charges of whatever nature, now or hereafter
imposed, levied, collected, withheld, or assessed by any jurisdiction, or by any
department,  agency,  state,  province or other political subdivision thereof or
therein (collectively, "Taxes"), excluding as to any Indemnified Tax Person, (i)
a Tax on the  Income  imposed  on such  Indemnified  Tax  Person  and  (ii)  any
interest,  fees,  additions to tax or penalties  for late payment  thereof (each
such  nonexcluded Tax, an "Indemnified  Tax"). For purposes hereof,  "Tax on the
Income"  shall  mean,  as to any Person,  a Tax imposed by one of the  following
jurisdictions or by any political  subdivision or taxing authority thereof:  (i)
the United States,  (ii) Canada,  (iii) the jurisdiction in which such Person is
organized,  (iv) the  jurisdiction  in which such Person's  principal  office or
lending offices are located; which Tax is an income tax or franchise tax imposed
on all or part of the net  income  or net  profits  of such  Person or which Tax
represents  interest,  fees, or penalties for late payment of such an income tax
or franchise tax.

     (b)  Grossing Up of  Payments.  If any Credit  Party or any other Person is
required by any law, rule, regulation,  order, directive, treaty or guideline to
make  any  deduction  or  withholding  (which  deduction  or  withholding  would
constitute an Indemnified Tax) from any amount required to be paid by any Credit
Party to or on behalf of an Indemnified Tax Person under any Loan Document, then
(i) such Credit  Party shall pay such  Indemnified  Tax before the date on which
penalties  attach  thereto,  such payment to be made for its own account (if the
liability  to pay is  imposed on such  Credit  Party) or on behalf of and in the
name of such  Indemnified  Tax  Person  (if the  liability  is  imposed  on such
Indemnified Tax Person), and (ii) the sum payable to such Indemnified Tax Person
shall be  increased  as may be  necessary  so that  after  making  all  required
deductions and withholdings (including deductions and withholdings applicable to
additional sums payable under this Section) such Indemnified Tax Person receives
an amount  equal to the sum it would have  received  had no such  deductions  or
withholdings been made; provided,  however, that no such additional amount shall

<PAGE>

be  payable  if any such  Taxes are  required  to be paid by reason  only of the
payees having some connection with a Canadian  taxing  jurisdiction,  other than
the receipt of the payments to be made under this  Agreement and the holding and
disposition of the Term Notes issued pursuant to this Agreement. Notwithstanding
the foregoing,  as to the Parent  Facility  only, no additional  amount shall be
required  to be paid to any  Indemnified  Tax Person  under  clause  (ii) of the
preceding  sentence  except  to the  extent  that the  requirement  to deduct or
withhold or the amount thereof is attributable to (i) the introduction after the
Effective  Date of any law, rule or regulation  requiring any Person to withhold
or deduct any amount from any payment under the Loan  Documents in respect of an
Indemnified Tax or (ii) any increase after the Effective Date in the rate of any
such withholding or deduction.

     (c) Other  Taxes.  Each Credit Party  agrees,  to pay any current or future
stamp or  documentary  taxes or any other excise or property  taxes,  charges or
similar levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or any amendment, supplement or modification of, or
any waiver or consent  under or in respect of, the Loan  Documents  or otherwise
with respect to, the Loan Documents (collectively, the "Other Taxes").

     (d)  Evidence  of  Payment.  Within 30 days  after the  reasonable  request
therefor by the Agent in  connection  with any payment of  Indemnified  Taxes or
Other  Taxes,  each  Credit  Party will  furnish to the Agent the  original or a
certified copy of an official  receipt from the jurisdiction to which payment is
made  evidencing  payment  thereof  or, if  unavailable,  a  certificate  from a
Financial  Officer  that  states  that such  payment has been made and that sets
forth the date and amount of such payment.

     (e) U.S. Tax  Certificates.  Each  Indemnified Tax Person that is organized
under the laws of any jurisdiction other than the United States or any political
subdivision  thereof that is exempt from United States federal  withholding tax,
or that is subject to such tax at a reduced  rate  under an  applicable  treaty,
with respect to payments under the Loan Documents shall deliver to the Agent for
transmission to each Borrower, on or prior to the Effective Date (in the case of
each  Indemnified  Tax Person  listed on the  signature  pages hereof) or on the
effective  date of the  Assignment  and  Acceptance  Agreement or other document
pursuant  to which it  becomes  an  Indemnified  Tax Person (in the case of each
other  Indemnified  Tax  Person),  and at such other times as may be required by
applicable  law,   Internal  Revenue  Form  4224  or  Form  1001  or  any  other
certificates  or  documents  required  under  United  States  law  to  establish
entitlement to such exemption or reduced rate. In addition, each Indemnified Tax
Person shall deliver the forms described above promptly upon the obsolescence or
invalidity of any form previously  delivered by such Indemnified Tax Person.  No
Credit  Party  shall  be  required  to pay any  additional  amount  to any  such
Indemnified Tax Person under subsection (b) above if such Indemnified Tax Person
shall have failed to satisfy the  requirements of the two immediately  preceding

<PAGE>

sentences;  provided that if such  Indemnified  Tax Person shall have  satisfied
such  requirements  on the Effective Date (in the case of each  Indemnified  Tax
Person  listed on the signature  pages  hereof) or on the effective  date of the
Assignment  and  Acceptance  Agreement  or other  document  pursuant to which it
became an  Indemnified  Tax Person (in the case of each  other  Indemnified  Tax
Person),  nothing in this  subsection  shall  relieve  any  Credit  Party of its
obligation  to pay any  additional  amounts  pursuant to  subsection  (b) to the
extent  that,  as a result  of any  change in  applicable  law or  treaty,  such
Indemnified Tax Person is no longer properly  entitled to deliver  certificates,
documents or other evidence at a subsequent date establishing the fact that such
Indemnified Tax Person is entitled to such exemption or reduced rate.

     (f) In the event that an  Indemnified  Tax Person is  entitled to receive a
refund of or credit for or  remission  or  repayment  of taxes  withheld or paid
pursuant  to this  Section  3.10  ("Tax  Credit"),  which  credit  or  refund is
identifiable by such  Indemnified Tax Person as being a result of taxes withheld
in connection with sums payable hereunder or under any other Loan Document, such
Indemnified  Tax Person shall use  reasonable  efforts to obtain the Tax Credit,
and upon  receipt of such Tax  Credit  shall  promptly  notify the Agent and the
Borrowers  and  shall  remit to the  Borrowers  the  amount  of such Tax  Credit
(without interest)  allocable to payments made hereunder or under the other Loan
Documents.

3.11 Option to Fund

     Each  Lender  has  indicated  that,  if a Borrower  requests  a  Eurodollar
Advance,  such Lender may wish to purchase one or more deposits in order to fund
or maintain its funding of its Commitment  Percentage of such Eurodollar Advance
during the Interest Period with respect  thereto;  it being  understood that the
provisions of this Agreement  relating to such funding are included only for the
purpose  of  determining  the rate of  interest  to be paid in  respect  of such
Eurodollar Advance and any amounts owing under Sections 3.5 and 3.7. Each Lender
shall be  entitled to fund and  maintain  its funding of all or any part of each
Eurodollar  Advance  in any  manner  it sees  fit,  but all such  determinations
hereunder shall be made as if each Lender had actually funded and maintained its
Commitment  Percentage of each Eurodollar Advance during the applicable Interest
Period  through the  purchase of deposits in the London  interbank  market in an
amount equal to its Commitment  Percentage of such  Eurodollar  Advance having a
maturity  corresponding  to such  Interest  Period.  Any  Lender  may  fund  its
Commitment  Percentage of each Eurodollar Advance from or for the account of any
branch or office of such Lender as such Lender may choose from time to time.

3.12 Replacement of Lenders

     Notwithstanding the foregoing, if (i) any Lender shall request compensation
pursuant  to Section 3.6 or a Borrower  shall be required to pay any  additional
amounts pursuant to Section 3.10 in respect of any Lender in an aggregate amount
in excess of $50,000, (ii) any Lender shall give any notice to a Borrower or the
Agent  pursuant to Section 3.7,  (iii) any Lender shall on two or more occasions
give a notice to the Borrowers or the Agent pursuant to Section 3.8, or (iv) any

<PAGE>

Lender shall be an uncured Defaulting Lender on two or more occasions;  then, in
each such case,  provided  that no Default or Event of Default  shall then exist
and be continuing, during the 90 day period after the receipt of such request or
notice,  such  Borrower may require that such Lender  transfer all of its right,
title and interest  under this  Agreement and each of such Lender's Notes to any
lender identified by such Borrower (a "Proposed Lender") if such Proposed Lender
agrees to assume all of the obligations of such Lender for  consideration  equal
to the outstanding  principal amount of such Lender's Loans and all unreimbursed
sums paid by such Lender under Section 2.8(b), together with interest thereon to
the date of such transfer and all other amounts payable under the Loan Documents
to such  Lender  on or prior to the date of such  transfer  (including  any fees
accrued hereunder and any amounts which would be payable under Section 3.5 as if
all of such Lender's Loans were being prepaid in full on such date).  Subject to
the  execution  and  delivery of new Notes,  an  instrument  of  assignment  and
assumption, and such other documents as such Lender may reasonably require, such
Proposed  Lender  shall  be a  "Lender"  for  all  purposes  hereunder.  Without
prejudice to the survival of any other agreement of the Borrowers hereunder, the
agreements of the Borrowers contained in Sections 3.5, 3.6, 11.5, 11.8 and 11.10
(without  duplication  of any payments made to such Lender by one or both of the
Borrowers or the Proposed  Lender)  shall  survive for the benefit of any Lender
replaced under this Section with respect to the time prior to such replacement.

4.   REPRESENTATIONS AND WARRANTIES

     In order to induce the Agent and the  Lenders to enter into this  Agreement
and to make the Loans and the  Issuing  Bank to issue the  Letters of Credit and
the  Lenders  to  participate   therein,   each  Borrower  makes  the  following
representations and warranties to the Agent, the Issuing Bank and each Lender:

4.1  Subsidiaries; Capitalization

     As of the Effective Date, GP Canada has no Subsidiaries  and the Parent has
only the Subsidiaries  set forth on, and the authorized,  issued and outstanding
Capital  Stock of the  Parent  and each  such  Subsidiary  is as set  forth  on,
Schedule 4.1. As of the Effective  Date, GP Canada is a wholly-owned  Subsidiary
of  Physics  and  except  as set  forth on  Schedule  4.1,  the  shares  of,  or
partnership  or other  interests in, each  Subsidiary of the Borrowers are owned
beneficially  and of record by a Borrower or another  Subsidiary  of a Borrower,
are free and clear of all Liens and are duly authorized,  validly issued,  fully
paid  and  nonassessable.  As of the  Effective  Date,  except  as set  forth on
Schedule 4.1, (i) no Credit Party nor any of the Foreign Subsidiaries has issued
any  securities  convertible  into,  or options or warrants  for,  any common or
preferred equity securities thereof, (ii) there are no agreements, voting trusts
or  understandings  binding  upon any Borrower or any of its  Subsidiaries  with
respect to the voting  securities of any Borrower or any of its  Subsidiaries or
affecting  in any  manner  the sale,  pledge,  assignment  or other  disposition
thereof, including any right of first refusal, option, redemption, call or other

<PAGE>

right  with  respect  thereto,  whether  similar  or  dissimilar  to  any of the
foregoing,  and (iii) all of the outstanding  Capital Stock of each Credit Party
or Foreign Subsidiary is owned by a Borrower or another Credit Party.

4.2  Existence and Power

     Each Borrower,  each Credit Party and each of the Foreign  Subsidiaries  is
duly  incorporated,  organized or formed and validly  existing in good  standing
under the laws of the jurisdiction of its  incorporation  or formation,  has all
requisite  power and  authority to own its Property and to carry on its business
as now conducted,  and is in good standing and authorized to do business in each
jurisdiction  in which  the  nature of the  business  conducted  therein  or the
Property owned by it therein makes such  qualification  necessary,  except where
such  failure to qualify  could not  reasonably  be  expected to have a Material
Adverse Effect.

4.3   Authority and Execution

     Each Borrower,  each Credit Party and each of the Foreign  Subsidiaries has
full legal power and authority to enter into,  execute,  deliver and perform the
terms of the Loan  Documents  to which it is a party all of which have been duly
authorized  by  all  proper  and  necessary  corporate,   partnership  or  other
applicable action and is in full compliance with its Organizational Documents.

4.4  Binding Agreement

     The Loan Documents (other than the Notes)  constitute,  and the Notes, when
issued and delivered  pursuant hereto for value received,  will constitute,  the
valid and legally  binding  obligations  of each Credit  Party and each  Foreign
Subsidiary,  in each case, to the extent it is a party  thereto,  enforceable in
accordance with their respective  terms,  except as such  enforceability  may be
limited by applicable  bankruptcy,  insolvency,  reorganization or other similar
laws now or hereafter  affecting the enforcement of creditors'  rights generally
and except that the remedy of specific  performance and other equitable remedies
are subject to judicial discretion.

4.5  Litigation

     Except  as set  forth on  Schedule  4.5,  there  are no  actions,  suits or
proceedings  at law or in  equity  or by or before  any  Governmental  Authority
(whether purportedly on behalf of any Borrower, any other Credit Party or any of
the  Foreign  Subsidiaries)  pending  or,  to the  knowledge  of  any  Borrower,
threatened  against any  Borrower,  any other Credit Party or any of the Foreign
Subsidiaries or maintained by any Borrower, any other Credit Party or any of the
Foreign  Subsidiaries  or which may affect the Property of any Borrower,  or any
other Credit Party or any of the Foreign Subsidiaries or any of their respective
Properties or rights,  which (i) could reasonably be expected to have a Material

<PAGE>

Adverse Effect,  (ii) call into question the validity or  enforceability  of, or
otherwise seek to invalidate, any Loan Document, or (iii) might, individually or
in the  aggregate,  materially  and  adversely  affect  any of the  transactions
contemplated by any Loan Document.

4.6  Required Consents

     Except for information  filings  required to be made in the ordinary course
of business which are not a condition to the  performance by any Borrower or any
of its Subsidiaries under the Loan Documents to which it is a party, no consent,
authorization  or  approval  of,  filing  with,  notice  to,  or  exemption  by,
stockholders or holders of any other equity interest, any Governmental Authority
or any other Person is required to authorize,  or is required in connection with
the  execution,  delivery or  performance  of the Loan  Documents  to which such
Borrower or any of its  Subsidiaries is a party or is required as a condition to
the validity or enforceability of the Loan Documents to which any of the same is
a party.  Each Borrower,  prior to each borrowing by it hereunder,  has obtained
all necessary approvals and consents of, and has filed or caused to be filed all
reports,  applications,  documents,  instruments and information  required to be
filed pursuant to all applicable laws,  rules,  regulations and requests of, all
Governmental Authorities in connection with such borrowing.

4.7  Absence of Defaults; No Conflicting Agreements

     (a) No Borrower,  no other Credit Party nor any of the Foreign Subsidiaries
is in default under any mortgage,  indenture,  contract or agreement to which it
is a party or by which it or any of its  Property is bound,  the effect of which
default could  reasonably  be expected to have a Material  Adverse  Effect.  The
execution,  delivery or carrying out of the terms of the Loan Documents will not
constitute  a default  under,  or result in the  creation or  imposition  of, or
obligation  to create,  any Lien upon any  Property of any  Borrower,  any other
Credit  Party or any of the  Foreign  Subsidiaries  or  result in a breach of or
require the  mandatory  repayment of or other  acceleration  of payment under or
pursuant to the terms of any such mortgage, indenture, contract or agreement.

     (b) No Borrower nor any of its  Subsidiaries  is in default with respect to
any judgment,  order, writ,  injunction,  decree or decision of any Governmental
Authority which default could  reasonably be expected to have a Material Adverse
Effect.

4.8 Compliance with Applicable Laws

     Each Borrower, each other Credit Party and each of the Foreign Subsidiaries
is complying in all material respects with all statutes,  regulations, rules and
orders of all  Governmental  Authorities  which are  applicable to such Borrower
such other Credit Party or such Foreign  Subsidiary,  a violation of which could
reasonably be expected to have a Material Adverse Effect.

<PAGE>

4.9 Taxes

     Each  Borrower,   each  other  Credit  Party,   and  each  of  the  Foreign
Subsidiaries  has filed or caused to be filed  all tax  returns  required  to be
filed and has paid, or has made adequate provision for the payment of, all taxes
shown to be due and payable on said returns or in any  assessments  made against
it (other than those being  contested as required under Section 7.4) which would
be  material  to  such  Borrower,  such  other  Credit  Party  or  such  Foreign
Subsidiaries,  and no tax Liens  have  been  filed  with  respect  thereto.  The
charges,  accruals and reserves on the books of each Borrower, each other Credit
Party and each of the  Subsidiaries  with  respect to all taxes are, to the best
knowledge  of each  Borrower,  adequate  for the payment of such  taxes,  and no
Borrower  knows of any unpaid  assessment  which is due and payable  against any
Borrower,  any other  Credit  Party or any of the  Foreign  Subsidiaries  or any
claims  being  asserted  which could  reasonably  be expected to have a Material
Adverse  Effect,  except such thereof as are being  contested as required  under
Section 7.4, and for which  adequate  reserves have been set aside in accordance
with GAAP.

4.10 Governmental Regulations

     No Borrower,  no other Credit Party,  no Foreign  Subsidiary nor any Person
controlled by, controlling, or under common control with, any Borrower or any of
its  Subsidiaries,  is subject to regulation  under the Public  Utility  Holding
Company Act of 1935,  as  amended,  the  Federal  Power Act, as amended,  or the
Investment  Company  Act of 1940,  as  amended,  or is subject to any statute or
regulation   which  prohibits  or  restricts  the  incurrence  of  Indebtedness,
including statutes or regulations  relative to common or contract carriers or to
the sale of electricity, gas, steam, water, telephone, telegraph or other public
utility services.

4.11 Federal Reserve Regulations; Use of Loan Proceeds

     No Borrower,  no other Credit Party and nor any of the Foreign Subsidiaries
is engaged principally,  or as one of its important activities,  in the business
of extending  credit for the purpose of purchasing or carrying any Margin Stock.
After giving effect to the making of each Revolving Credit Loan and the issuance
of each  Letter of Credit,  Margin  Stock will  constitute  less than 25% of the
assets  (as  determined  by any  reasonable  method)  of each  Borrower  and its
Subsidiaries.

4.12 Plans

     (a) Each Employee  Benefit Plan is in  compliance  with ERISA and the Code,
where applicable,  in all material respects,  except where  non-compliance could
not  reasonably  be  expected  to  have a  Material  Adverse  Effect.  As of the
Effective  Date, (i) the amount of all Unfunded  Pension  Liabilities  under the
Pension  Plans,  excluding  any plan which is a  Multi-employer  Plan,  does not
exceed  $250,000,  and (ii) the  amount of the  aggregate  Unrecognized  Retiree

<PAGE>

Welfare  Liability under all applicable  Employee  Benefit Plans does not exceed
$250,000.  Each Borrower and each of its  Subsidiaries  and ERISA Affiliates has
complied  with the  requirements  of Section  515 of ERISA with  respect to each
Pension Plan which is a Multi-employer  Plan, except where  non-compliance could
not  reasonably  be  expected  to  have a  Material  Adverse  Effect.  As of the
Effective Date, no Borrower nor its  Subsidiaries  or ERISA  Affiliates have any
liability  under  Section 4201 or 4204 of ERISA  (including  the  obligation  to
satisfy secondary  liability as a result of purchaser default) and the aggregate

Title IV of ERISA, of the Borrowers and their  Subsidiaries and ERISA Affiliates
with  respect  to  all  Pension   Plans  which  are   Multi-employer   Plans  is
approximately  $250,000. Each Borrower and its Subsidiaries and ERISA Affiliates
have, as of the Effective Date, made all  contributions  or payments to or under
each such Pension Plan  required by law or the terms of such Pension Plan or any
contract or agreement with respect thereto,  except where  non-compliance  could
not  reasonably  be  expected  to have a Material  Adverse  Effect.  No material
liability  to the PBGC has been,  or is  expected  by any  Borrower,  any of its
Subsidiaries or any ERISA  Affiliate to be,  incurred by any Borrower,  any such
Subsidiary  or any  ERISA  Affiliate,  except  where  non-compliance  could  not
reasonably be expected to have a Material Adverse Effect. Liability, as referred
to in this  Section  includes  any joint and several  liability.  Each  Employee
Benefit  Plan  which is a group  health  plan  within  the  meaning  of  Section
5000(b)(1) of the Code is in material compliance with the continuation of health
care  coverage   requirements  of  Section  4980B  of  the  Code,  except  where
non-compliance  could not  reasonably  be  expected  to have a Material  Adverse
Effect.

     (b) All  contributions  required  under  applicable  law have  been made in
respect of all pension  plans of GP Canada and each such  pension  plan is fully
funded on an ongoing and termination basis.

Statements  of  Operations,  Stockholder's  Equity and Cash Flows for the fiscal

Consolidating  financial  condition and results of the  operations of Parent and
its Subsidiaries as of the dates and for the periods indicated therein (subject,
in the case of such unaudited  statements,  to normal year-end  adjustments) and

Statements or in the notes thereto,  neither Parent nor any of its  Subsidiaries
has any obligation or liability of any kind (whether fixed, accrued, Contingent,

<PAGE>

unmatured or otherwise)  which, in accordance with GAAP,  should have been shown
on the  Financial  Statements  and was  not.  Since  the  date of the  Financial
Statements,  Parent and each of its Subsidiaries has conducted its business only

personal  property,  in each case which is material to the  Borrowers  and their
Subsidiaries, taken as a whole, subject to no Liens, except Permitted Liens. All
leases of  Property  to any  Borrower,  any Credit  Party or any of the  Foreign
Subsidiaries are in full force and effect,  such Borrower,  such Credit Party or
such  Foreign  Subsidiary,  as the case may be,  enjoys  quiet  and  undisturbed
possession  under all leases of real property and no Borrower,  any other Credit

     Each Borrower,  each Credit Party and each Foreign Subsidiary  possesses or
has the right to use all  franchises,  licenses and other rights as are material

in  compliance,  with no known  conflict  with the valid  rights of others which
could  reasonably be expected to have a Material  Adverse  Effect.  No event has
occurred which permits or, to the best knowledge of each Borrower,  after notice
or the  lapse of time or both,  or any  other  condition,  could  reasonably  be
expected to permit, the revocation or termination of any such franchise, license
or other right which  revocation or termination  could reasonably be expected to
have a Material Adverse Effect.

     Except as set forth in Schedule  4.16,  no Borrower,  no other Credit Party
nor any of the Foreign Subsidiaries (i) has received written notice or otherwise
learned of any claim, demand, action, event, condition,  report or investigation

of any toxic or hazardous  waste,  substance or constituent,  or other substance

notice of any federal, state or provincial  investigation evaluating whether any
remedial  action is needed to respond to a release or threatened  release of any
toxic or hazardous  waste,  substance or constituent or other substance into the
environment  for which any Borrower any other Credit Party or any of the Foreign
Subsidiaries is or would be liable, which liability could reasonably be expected
to have a  Material  Adverse  Effect,  or (iv)  has  received  notice  that  any
Borrower, any other Credit Party or any of the Foreign Subsidiaries is or may be
liable  to  any  Person   under  the   Comprehensive   Environmental   Response,
Compensation and Liability Act, as amended,  42 U.S.C.  Section 9601 et seq., or
any analogous state or foreign law, which liability could reasonably be expected
to have a Material Adverse Effect. Each Borrower,  each other Credit Party, each
of the Foreign  Subsidiaries is in compliance with the financial  responsibility
requirements of federal and state  environmental  laws to the extent applicable,
including  those contained in 40 C.F.R.,  parts 264 and 265,  subpart H, and any

7.5  Insurance

     (a)  Insurance.  Maintain,  and  cause  each  Credit  Party and each of the
Foreign  Subsidiaries to maintain,  insurance with  financially  sound insurance
carriers on such of its Property,  against at least such risks,  and in at least
such amounts,  as are usually insured against by similar  businesses,  including
public  liability  (bodily  injury  and  property  damage),  fidelity,  business
interruption, and workers' compensation with deductibles which are customary for
companies  engaged in similar  businesses,  and which,  in the case of  property
insurance,  shall be (i) in amounts  sufficient  to prevent any Borrower or such
Subsidiary from becoming a co-insurer, and (ii) against all risks; and file with
the Agent  within  ten days  after  request  therefor  a  detailed  list of such
insurance then in effect,  stating the names of the carriers thereof, the policy
numbers, the insureds thereunder,  the amounts of insurance, dates of expiration
thereof, and the Property and risks covered thereby, together with a certificate
of the  Financial  Officer (or such other  officer as shall be acceptable to the
Agent) of such  Borrower  certifying  that in the opinion of such  officer  such
insurance is adequate in nature and amount, complies with the obligations of the
Borrowers under this Section, and is in full force and effect.

     (b) Insurance Covering Collateral.  Promptly upon request therefor, deliver
or cause to be  delivered to the Agent  originals or duplicate  originals of all
such policies of insurance covering the Collateral.  All such insurance policies
in respect of property  insurance  and  business  interruption  insurance  shall
contain a standard loss payable clause and shall be endorsed to provide that, in
respect of the interests of the Agent, the Issuing Bank and the Lenders: (i) the
Agent shall be an additional insured,  (ii) 30 days' prior written notice of any
cancellation,  reduction of amounts payable, or any changes and amendments shall
be given to the Agent,  and (iii) the Agent  shall  have the right,  but not the
obligation,  to pay any premiums due or to acquire other such insurance upon the
failure of a Borrower or such  Subsidiary  to pay the same or to so insure.  All
property  insurance  policies shall name the Agent as sole loss payee in respect
of each claim  relating to the  Collateral  and resulting in a payment under any
such insurance policy exceeding $1,000,000. Provided that no Default or Event of
Default shall exist, the Agent agrees, promptly upon its receipt thereof, to pay
over to the  Parent,  the  applicable  Credit  Party or the  applicable  Foreign
Subsidiary  that owns the  applicable  Property  the proceeds of such payment to
enable  the  Parent,  the  applicable  Credit  Party or the  applicable  Foreign
Subsidiary to repair,  restore or replace the Property subject to such claim. To
the extent that such the  Parent,  the Credit  Party or the  Foreign  Subsidiary
fails to repair, restore or replace such Property subject to a claim, subject to
Section 2.2(c), an amount equal to such proceeds shall be immediately applied as
a permanent reduction of the Aggregate Parent Commitment Amount and/or Aggregate
GP Canada Credit Exposure,  as the case may be, pursuant to Section 2.4(b). If a
Default  or Event of  Default  shall then  exist,  the Agent  shall (i) hold the
proceeds of such  payment as  Collateral  until such Default or Event of Default
shall no  longer  exist  and then pay over the same to such  Borrower  or Credit
Party to enable such  Borrower or Credit Party to repair,  restore or replace or
cause to be repaired,  restored or replaced  the  Property  subject to the claim

<PAGE>

which  resulted in such  payment or (ii) hold such  proceeds as  Collateral  and
apply the same to the  obligations  of the Parent or Credit Party under the Loan
Documents in such order,  in such  amounts and at such times as the Agent,  with
the consent of Required Lenders, shall decide.

     (c) Concurrent  Insurance.  No Borrower nor any of its  Subsidiaries  shall
take out separate  insurance  concurrent in form or contributing in the event of
loss with that required to be maintained pursuant to subsection (b) above unless
the Agent has  approved  the carrier  and the form and content of the  insurance
policy,  including naming the Agent as an additional insured and sole loss payee
thereunder.

7.6  Performance of Obligations

     Pay and  discharge  when due,  and cause each Credit  Party and each of the
Foreign Subsidiaries so to do, all lawful  Indebtedness,  obligations and claims
for  labor,  materials  and  supplies  or  otherwise  which,  if  unpaid,  could
reasonably be expected to (i) have a Material  Adverse Effect,  or (ii) become a
Lien upon  Property of any  Borrower,  any Credit  Party,  or any of the Foreign
Subsidiaries other than a Permitted Lien, unless and to the extent only that the
validity of such  Indebtedness,  obligation  or claim shall be contested in good
faith and by  appropriate  proceedings  diligently  conducted  and that any such
contested Indebtedness, obligations or claims shall not constitute, or create, a
Lien on any  Property of a  Borrower,  any Credit  Party,  or any of the Foreign
Subsidiaries  senior  to the  Lien,  if any,  granted  to the  Agent  under  the
Collateral  Documents on such  Property,  and provided  that the Parent,  Credit
Party or  Foreign  Subsidiary  shall  give the Agent  prompt  notice of any such
contest  and that  such  reserve  or  other  appropriate  provision  as shall be
required  by the  Accountants  in  accordance  with  GAAP  shall  have been made
therefor.

7.7  Condition of Property

     At all times, maintain,  protect and keep in good repair, working order and
condition  (ordinary  wear and tear  excepted),  and  cause  each of the  Credit
Parties  and  Foreign  Subsidiaries  so to do,  all  Property  necessary  to the
operation of any Credit Party's or such Foreign Subsidiary's business.

7.8  Observance of Legal Requirements

     Observe and comply in all respects,  and cause each of its  Subsidiaries so
to do,  with  all  laws,  ordinances,  orders,  judgments,  rules,  regulations,
certifications,  franchises,  permits, licenses,  directions and requirements of
all  Governmental  Authorities,  which  now  or at  any  time  hereafter  may be
applicable  to it, a violation of which could  reasonably  be expected to have a
Material Adverse Effect, except such thereof as shall be contested in good faith
and by appropriate  proceedings  diligently  conducted by it,  provided that the
Borrowers  shall  give the Agent  prompt  notice of such  contest  and that such

<PAGE>

reserve or other  appropriate  provision as shall be required by the Accountants
in accordance with GAAP shall have been made therefor.

7.9  Inspection of Property; Books and Records; Discussions

expense (unless an Event of Default has occurred and is continuing in which case
it shall be at the Borrowers'  expense) permit  representatives of the Agent and
each Lender to visit the offices of each  Borrower,  each other Credit Party and
each  Foreign  Subsidiary,   to  examine  the  books  and  records  thereof  and
Accountants' reports relating thereto, and to make copies or extracts therefrom,
to discuss  the  affairs of each  Borrower,  each  other  Credit  Party and each
Foreign  Subsidiary  with the respective  officers  thereof,  and to examine and

10.  THE AGENT

10.1 Appointment

     Each of the Issuing Bank and each Lender hereby irrevocably  designates and
appoints  Fleet as the Agent of the Issuing  Bank and such Lender under the Loan
Documents  and  each of the  Issuing  Bank and each  Lender  hereby  irrevocably
authorizes  the Agent to take such action on its behalf under the  provisions of
the Loan  Documents  and to exercise  such powers and perform such duties as are
expressly  delegated to the Agent by the terms of the Loan  Documents,  together
with such other powers as are reasonably  incidental thereto.  The duties of the
Agent shall be mechanical and administrative in nature, and, notwithstanding any
provision to the contrary  elsewhere in any Loan  Document,  the Agent shall not
have any  duties  or  responsibilities  other  than  those  expressly  set forth
therein,  or any fiduciary  relationship with, or fiduciary duty to, the Issuing
Bank or any  Lender,  and no  implied  covenants,  functions,  responsibilities,
duties,  obligations  or  liabilities  shall be read into the Loan  Documents or
otherwise exist against the Agent.

10.2 Delegation of Duties

     The Agent may  execute  any of its duties  under the Loan  Documents  by or
through  agents or  attorneys-in-fact  and shall be entitled  to rely upon,  and

<PAGE>

shall be fully  protected in, and shall not be under any liability for,  relying
upon, the advice of counsel concerning all matters pertaining to such duties.

10.3 Exculpatory Provisions

     Neither the Agent nor any of its officers,  directors,  employees,  agents,
attorneys-in-fact  or  affiliates  shall be (i) liable  for any action  lawfully
taken or omitted to be taken by it or such Person  under or in  connection  with
the Loan  Documents  (except for its or such  Person's own gross  negligence  or
willful  misconduct),  or (ii)  responsible in any manner to the Issuing Bank or
any of the Lenders for any recitals,  statements,  representations or warranties
made by any Borrower or any other Credit Party or any officer thereof  contained
in the Loan Documents or in any certificate, report, statement or other document
referred to or provided for in, or received by the Agent under or in  connection
with, the Loan Documents or for the value, validity, effectiveness, genuineness,
perfection,  enforceability  or  sufficiency of any of the Loan Documents or for
any failure of any  Borrower or any other  Credit  Party or any other  Person to
perform its obligations thereunder.  The Agent shall not be under any obligation
to  the  Issuing  Bank  or any  Lender  to  ascertain  or to  inquire  as to the
observance or performance  of any of the agreements  contained in, or conditions
of, the Loan  Documents,  or to inspect  the  Property,  books or records of any
Borrower  or any  other  Credit  Party  .  The  Issuing  Bank  and  the  Lenders
acknowledge that the Agent shall not be under any duty to take any discretionary
action  permitted under the Loan Documents  unless the Agent shall be instructed
in  writing  to do so  by  the  Issuing  Bank  and  Required  Lenders  and  such
instructions  shall be  binding  on the  Issuing  Bank and all  Lenders  and all
holders of the Notes; provided, however, that the Agent shall not be required to
take any action which exposes the Agent to personal  liability or is contrary to
law or any  provision  of the Loan  Documents.  The Agent shall not be under any
liability or responsibility  whatsoever, as Agent, to any Borrower, or any other
Credit  Party or any other  Person as a  consequence  of any failure or delay in
performance,  or any  breach,  by the  Issuing  Bank or any Lender of any of its
obligations under any of the Loan Documents.

10.4 Reliance by Agent

     The  Agent  shall be  entitled  to rely,  and shall be fully  protected  in
relying, upon any writing, resolution, notice, consent, certificate,  affidavit,
opinion,  letter,  cablegram,  telegram,  telecopy,  telex or teletype  message,
statement,  order or other document or conversation believed by it to be genuine
and correct and to have been signed,  sent or made by a proper Person or Persons
and upon  advice  and  statements  of legal  counsel  (including  counsel to any
Borrower or any other Credit Party),  independent  accountants and other experts
selected by the Agent.  The Agent may treat the Issuing Bank or each Lender,  as
the case may be, or the Person designated in the last notice filed with it under
this Section,  as the holder of all of the interests of the Issuing Bank or such
Lender,  as the case may be, in its Loans,  in its Notes,  the Letters of Credit

<PAGE>

and the  Reimbursement  Obligations,  as  applicable,  until  written  notice of
transfer, signed by the Issuing Bank or such Lender (or the Person designated in
the last  notice  filed with the Agent)  and by the  Person  designated  in such
written  notice of transfer,  in form and substance  satisfactory  to the Agent,
shall have been filed with the Agent.  The Agent  shall not be under any duty to
examine or pass upon the validity, effectiveness,  enforceability or genuineness
of the Loan Documents or any  instrument,  document or  communication  furnished
pursuant thereto or in connection therewith,  and the Agent shall be entitled to
assume that the same are valid,  effective and genuine, have been signed or sent
by the proper  parties and are what they purport to be. The Agent shall be fully
justified  in failing or  refusing to take any action  under the Loan  Documents
unless it shall first receive such advice or concurrence of the Required Lenders
as it deems  appropriate.  The Agent  shall in all cases be fully  protected  in
acting,  or in refraining  from acting,  under the Loan  Documents in accordance
with a request  or  direction  of the  Required  Lenders,  and such  request  or
direction  and any  action  taken or failure to act  pursuant  thereto  shall be
binding  upon the Issuing  Bank,  all the Lenders and all future  holders of the
Notes and the Reimbursement Obligations.

10.5 Notice of Default

     The Agent shall not be deemed to have knowledge or notice of the occurrence
of any Default or Event of Default unless the Agent has received  written notice
thereof  from the Issuing  Bank,  a Lender or a Borrower.  In the event that the
Agent  receives such a notice,  the Agent shall  promptly give notice thereof to
the Issuing Bank,  the Lenders and a Borrower.  The Agent shall take such action
with  respect to such  Default or Event of Default as shall be  directed  by the
Required Lenders, provided,  however, that unless and until the Agent shall have
received  such  directions,  the Agent may (but shall not be obligated  to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem to be in the best interests of the Lenders.

10.6  Non-Reliance on Agent and Other Lenders

     Each of the  Issuing  Bank  and each  Lender  expressly  acknowledges  that
neither  the Agent nor any of its  respective  officers,  directors,  employees,
agents,   attorneys-in-fact  or  affiliates  has  made  any  representations  or
warranties to it and that no act by the Agent hereinafter,  including any review
of the affairs of any  Borrower or any other  Credit  Party,  shall be deemed to
constitute any  representation  or warranty by the Agent to any Lender.  Each of
the  Issuing  Bank  and  each  Lender  represents  to the  Agent  that  it  has,
independently  and without  reliance  upon the Agent,  the  Issuing  Bank or any
Lender, and based on such documents and information as it has deemed appropriate
made its own  evaluation of and  investigation  into the  business,  operations,
Property,  financial and other condition and  creditworthiness  of each Borrower
and each  other  Credit  Party and the value and Lien  status of any  collateral
security  and made its own  decision to enter into this  Agreement.  Each of the

<PAGE>

Issuing Bank and each Lender also  represents  that it will,  independently  and
without  reliance upon the Agent,  the Issuing Bank or any Lender,  and based on
such  documents  and  information  as it shall  deem  appropriate  at the  time,
continue to make its own credit analysis, evaluations and decisions in taking or
not taking action under any Loan Document,  and to make such investigation as it
deems  necessary  to inform  itself as to the  business,  operations,  Property,
financial  and other  condition and  creditworthiness  of each Borrower and each
other  Credit  Party and the value and Lien status of any  collateral  security.
Except  for  notices,  reports  and other  documents  expressly  required  to be
furnished  to the Issuing  Bank and/or the Lenders by the Agent  hereunder,  the
Agent shall not have any duty or  responsibility  to provide the Issuing Bank or
any  Lender  with any  credit  or other  information  concerning  the  business,
operations,  Property,  financial and other condition or creditworthiness of any
Borrower  and any  other  Credit  Party  which at any  time  may  come  into the
possession of the Agent or any of its officers,  directors,  employees,  agents,
attorneys-in-fact or affiliates.

10.7 Indemnification

     Each Lender agrees to indemnify and hold harmless the Agent in its capacity
as such (to the extent not  promptly  reimbursed  by the  Borrowers  and without
limiting the  obligation  of the Borrowers to do so),  ratably  according to its
Aggregate Commitment Percentage or, in the event any Loans shall be outstanding,
its  Outstanding   Percentage,   from  and  against  any  and  all  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or disbursements  of any kind whatsoever  including any amounts paid to
the Lenders (through the Agent) by a Borrower or any other Credit Party pursuant
to the terms of the Loan Documents,  that are subsequently rescinded or avoided,
or must otherwise be restored or returned,  which may at any time  (including at
any time  following  the payment of the  Revolving  Credit  Loans and  Revolving
Credit  Notes) be imposed on,  incurred by or asserted  against the Agent in any
way  relating to or arising  out of the Loan  Documents  or any other  documents
contemplated by or referred to therein or the transactions  contemplated thereby
or any action  taken or omitted to be taken by the Agent under or in  connection
with any of the foregoing; provided, however, that no Lender shall be liable for
the payment of any portion of such liabilities,  obligations,  losses,  damages,
penalties,  actions,  judgments,  suits, costs, expenses or disbursements to the
extent  resulting  from the  finally  adjudicated  gross  negligence  or willful
misconduct of the Agent. Without limitation of the foregoing, each Lender agrees
to reimburse the Agent promptly upon demand for its pro rata share of any unpaid
costs and expenses  (including  reasonable fees and expenses of counsel) payable
by a Borrower  under Section 11.5 to the extent that the Agent has not been paid
such  fees or has not been  reimbursed  for such  costs  and  expenses,  by such
Borrower.  The failure of any Lender to reimburse the Agent promptly upon demand
for its pro rata share of any amount  required  to be paid by the Lenders to the
Agent as provided  in this  Section  shall not  relieve any other  Lender of its
obligation  hereunder  to  reimburse  the Agent  for its pro rata  share of such
amount,  but no Lender shall be responsible  for the failure of any other Lender
to  reimburse  the Agent for such other  Lender's pro rata share of such amount.
The agreements in this Section shall survive the  termination of the Commitments

<PAGE>

of all of the  Lenders and the  payment of all  amounts  payable  under the Loan
Documents.

10.8 Agent in Its Individual Capacity

     Fleet and its  affiliates  may make secured or unsecured  loans to,  accept
deposits from,  issue letters of credit for the account of, act as trustee under
indentures  of,  and  generally  engage  in any kind of  business  with,  either
Borrower or any other Credit Party as though Fleet were not Agent  hereunder and
Fleet did not arrange the transactions  contemplated hereby. With respect to the
Commitments  made  or  renewed  by  Fleet  and  the  Notes  issued  to,  and the
Reimbursement  Obligations owing to, Fleet, Fleet shall have the same rights and
powers  under the Loan  Documents  as any  Lender and may  exercise  the same as
though it were not the Agent, and the terms "Lender" and "Lenders" shall in each
case include Fleet.

10.9 Successor Agent

     If at any time the Agent deems it advisable, in its sole discretion, it may
submit to the Issuing Bank,  each of the Lenders and the Parent a written notice
of its  resignation as Agent under the Loan  Documents,  such  resignation to be
effective  upon the earlier of (i) the written  acceptance  of the duties of the
Agent under the Loan  Documents  by a  successor  Agent and (ii) on the 30th day
after the date of such notice.  Upon any such resignation,  the Required Lenders
shall have the right to appoint  from among the  Lenders  which is a  commercial
bank a successor  Agent.  If no successor  Agent shall have been so appointed by
the Required  Lenders and accepted such  appointment  in writing  within 30 days
after the retiring  Agent's giving of notice of  resignation,  then the retiring
Agent may, on behalf of the Issuing  Bank and the  Lenders,  appoint a successor
Agent, which successor Agent shall be a commercial bank organized under the laws
of the  United  States or any  State  thereof  and  having a  combined  capital,
surplus,  and  undivided  profits of at least  $250,000,000  and which  shall be
reasonably  acceptable to the Parent.  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,  privileges and duties
of the retiring Agent, and the retiring Agent's rights,  powers,  privileges and
duties as Agent under the Loan Documents shall be terminated. Each Borrower, the
other  Credit  Parties,  the Issuing  Bank and the Lenders  shall  execute  such
documents as shall be necessary to effect such  appointment.  After any retiring
Agent's  resignation as Agent,  the provisions of the Loan Documents shall inure
to its  benefit  as to any  actions  taken or omitted to be taken by it, and any
amounts owing to it, while it was Agent under the Loan Documents. If at any time
there shall not be a duly  appointed and acting Agent,  each Borrower  agrees to
make each payment due under the Loan Documents  directly to the Issuing Bank and
the Lenders entitled thereto during such time.

or partial  exercise of any right,  remedy,  power or  privilege  under any Loan
Document  preclude any other or further  exercise thereof or the exercise of any
other  right,  remedy,  power or  privilege.  The rights,  remedies,  powers and
privileges  under the Loan  Documents  are  cumulative  and not exclusive of any
rights, remedies, powers and privileges provided by law.

11.4 Survival of Representations and Warranties and Certain Obligations

     (a) All representations and warranties made under the Loan Documents and in
any  document,  certificate  or  statement  delivered  pursuant  thereto  or  in
connection  therewith  shall  survive  the  execution  and  delivery of the Loan
Documents.

     (b) The  obligations  of the Borrowers  under  Sections 3.5, 3.6, 3.7, 3.8,
3.9, 3.10, 11.5 and 11.8 shall survive the termination of the Commitments of all
of the  Lenders,  the  Letter  of  Credit  Commitment,  and the  payment  of the
Revolving Credit Loans, the  Reimbursement  Obligations,  the Term Loans and all
other amounts payable under the Loan Documents.

11.5 Expenses

     Each Borrower agrees,  promptly upon presentation of a statement or invoice
therefor,  and whether any Revolving Credit Loan is made or any Letter of Credit
is issued (i) to pay or reimburse  Fleet (in its capacity as Agent and arranger)
for all its respective  out-of-pocket  costs and expenses reasonably incurred in
connection with the development,  preparation, execution and syndication of, the
Loan Documents and any amendment, supplement or modification thereto (whether or
not executed or effective),  any documents prepared in connection  therewith and
the  consummation  of  the  transactions  contemplated  thereby,  including  the
reasonable fees and  disbursements of Special Counsel,  (ii) to pay or reimburse
each of the Issuing  Bank,  the Agent and the Lenders for all of its  reasonable
out-of-pocket costs and expenses, including reasonable fees and disbursements of
counsel, incurred in connection with (A) any Default or Event of Default and any
enforcement or collection  proceedings resulting therefrom or in connection with
the negotiation of any restructuring or "work-out" (whether  consummated or not)

<PAGE>

of the  obligations  of any Credit Party under any of the Loan Documents and (B)
the  enforcement of this Section and (iii) to pay,  indemnify,  and hold each of
the Issuing Bank, the Lenders,  and the Agent harmless from and against, any and
all  recording and filing fees and any and all  liabilities  with respect to, or
resulting from any delay in paying,  stamp,  excise and other similar taxes,  if
any,  which may be payable or determined  to be payable in  connection  with the
execution  and  delivery  of,  or  consummation  of  any  of  the   transactions
contemplated by, or any amendment,  supplement or modification of, or any waiver
or  consent  under or in  respect  of,  the Loan  Documents  and any such  other
documents,  and (iv) to pay,  indemnify and hold each of the Issuing  Bank,  the
Lenders and the Agent and each of its officers, directors and employees harmless
from and against any and all other  liabilities,  obligations,  claims,  losses,
damages, penalties,  actions, judgments, suits, costs, expenses or disbursements
of any  kind  or  nature  whatsoever  (including  reasonable  counsel  fees  and
disbursements)  with  respect to the  enforcement  and  performance  of the Loan
Documents, the use of the proceeds of the Revolving Credit Loans and the Letters
of  Credit  and  the  enforcement  and  performance  of  the  provisions  of any
subordination  agreement involving the Agent and the Lenders (all the foregoing,
collectively,  the "Indemnified Liabilities") and, if and to the extent that the
foregoing indemnity may be unenforceable for any reason, each Borrower agrees to
make the maximum payment not prohibited under applicable law; provided, however,
that the Borrowers  shall have no obligation to pay  Indemnified  Liabilities to
the Agent,  the Issuing Bank or any Lender arising from the finally  adjudicated
gross  negligence or willful  misconduct of the Agent,  the Issuing Bank or such
Lender or claims between one indemnified  party and another  indemnified  party.
The agreements in this Section shall survive the  termination of the Commitments
of all of the Lenders,  the Letter of Credit  Commitment  and the payment of all
amounts payable under the Loan Documents.

11.6 Lending Offices

     (a) Each  Lender  shall have the right at any time and from time to time to
transfer its Loans and Reimbursement Obligations to a different office, provided
that such Lender shall  promptly  notify the Agent and each Borrower of any such
change of office.  Such office  shall  thereupon  become such  Lender's  lending
office,  provided,  however,  that no Lender  shall be  entitled  to receive any
greater  amount under  Sections  3.5, 3.7 and 3.10, as a result of a transfer of
any such  Loans and  Reimbursement  Obligations  to a  different  office of such
Lender than it would be entitled to immediately  prior thereto unless such claim
would have arisen even if such transfer had not occurred.

     (b) Each Lender agrees that,  upon the  occurrence of any event giving rise
to any increased cost or indemnity under Sections 3.5, 3.7 and 3.10 with respect
to such Lender, it will, if requested by a Borrower,  use reasonable  efforts to
designate  another  lending office for any Loans and  Reimbursement  Obligations
affected by such event,  provided  that such  designation  is made on such terms
that such Lender and its lending office suffer no economic,  legal or regulatory
disadvantage,  with the object of avoiding the  consequence  of the event giving
rise to the operation of any such Section.  Nothing in this Section shall affect

<PAGE>

or postpone  any of the  obligations  of any Borrower or the right of any Lender
provided in Sections 3.5, 3.6, 3.7 and 3.10.

11.7 Successors and Assigns

     (a) This  Agreement,  the Notes and the other Loan  Documents  to which any
Borrower  is a party  shall be  binding  upon and inure to the  benefit  of such
Borrower,  the Lenders,  the Agent,  the Issuing Bank all future  holders of the
Notes and Reimbursement Obligations and their respective successors and assigns.
No  Borrower  shall  delegate  any  obligation  or duty under any Loan  Document
without  the prior  written  consent of the  Agent,  the  Issuing  Bank and each
Lender.

     (b)  Subject to Section  11.7(e),  any Lender may at any time assign all or
any portion of its rights under any Loan Document to any Federal Reserve Bank.

     (c) In addition to its rights under Section 11.7(b), each Lender shall have
the right to sell, assign, transfer or negotiate (each an "Assignment") all or a
portion  of its  Loans,  its  Commitment  and its Notes,  to any  subsidiary  or
Affiliate of such Lender, to any other Lender,  or to any other bank,  insurance
company, financial institution, pension fund, mutual fund or other similar fund,
provided  that (i)  each  such  Assignment  shall  be of a  constant,  and not a
varying, percentage of all of the assignor Lender's rights and obligations under
the Loan Documents,  (ii) the Commitment Amount of the Commitment assigned shall
be not less than  $5,000,000  or the full  Commitment  Amount  of such  assignor
Lender's Commitment, (iii) unless the assignee is another Lender or a subsidiary
or Affiliate of any Lender, or unless at the time of such Assignment an Event of
Default  shall exist,  Parent  shall have  consented  thereto in writing  (which
consent shall not be  unreasonably  withheld),  and (iv) the assignor Lender and
such  assignee  shall  deliver to the Agent three  copies of an  Assignment  and
Acceptance  Agreement  executed by each of them, along with an assignment fee in
the sum of $3,500 for the account of the Agent.  Upon  receipt of such number of
executed copies of each such Assignment and Acceptance  Agreement  together with
the  assignment  fee  therefor  and  Parent's  consent  to such  Assignment,  if
required,  the Agent shall  record the same and execute not less than two copies
of such Assignment and Acceptance  Agreement in the appropriate  place,  deliver
one such copy to the assignor and one such copy to the assignee, and deliver one
photocopy  thereof,  as  executed,  to  Parent.  From and after  the  Assignment
Effective Date  specified in, and as defined in, such  Assignment and Acceptance
Agreement,  the  assignee  thereunder  shall be a party hereto and shall for all
purposes of this  Agreement  and the other Loan  Documents  be deemed a "Lender"
and, to the extent  provided in such  Assignment and Acceptance  Agreement,  the
assignor Lender  thereunder  shall be released from its  obligations  under this
Agreement and the other Loan Documents. Each Borrower agrees that, if requested,
in connection  with each such  Assignment,  it shall at its own cost and expense
execute and deliver (1) to the Agent or such assignee a Revolving Credit Note in
a  maximum  principal  amount  equal  to the  Parent  Commitment  Amount  of the
Commitment  assumed by such assignee,  (2) to the Agent or such assignor Lender,
in the event that such assignor Lender shall not have assigned all of its Parent
Commitment,  a Revolving Credit Note in a maximum  principal amount equal to the

<PAGE>

Commitment  Amount of the  Commitment  retained by such  assignor,  in each case
either in escrow  pending the delivery of, or against  receipt of, such assignor
Lender's  existing  Revolving  Credit Note,  (3) to the Agent or such assignee a
Term Note in a principal  amount equal to the GP Canada Credit Exposure  assumed
by such  assignee,  and (4) to the Agent or such assignor  Lender,  in the event
that such  assignor  Lender shall not have  assigned all of its GP Canada Credit
Exposure,  a Term  Note in a  principal  amount  equal to the GP  Canada  Credit
Exposure  retained by such  assignor,  in each case either in escrow pending the
delivery of, or against receipt of, such assignor  Lender's  existing  Revolving
Credit Note.  The Agent shall be entitled to rely upon the  representations  and
warranties made by the assignee under each Assignment and Acceptance Agreement.

     (d) In addition to the  participations  provided for in Section 11.11, each
Lender may grant  participations  in all or any part of its Loans, its Notes and
its Commitments to one or more banks, insurance companies, pension funds, mutual
funds  or  other  financial  institutions,   provided  that  (i)  such  Lender's
obligations  under this  Agreement  and the other Loan  Documents  shall  remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties
to this  Agreement  and the other Loan  Documents  for the  performance  of such
obligations,  (iii) the applicable Borrower, the Agent, the Issuing Bank 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
the other Loan  Documents,  (iv) the  granting  of such  participation  does not
require that any  additional  loss,  cost or expense be borne by any Borrower at
any time, and (v) the voting rights of any holder of any participation  shall be
limited to decisions that in accordance with Section 11.1 require the consent of
all of the Lenders.

     (e) No Lender shall,  as between and among the  Borrowers,  the Agent,  the
Issuing Bank and such Lender,  be relieved of any of its  obligations  under the
Loan  Documents as a result of any  assignment of or granting of  participations
in, all or any part of its Loans,  its  Commitment  and its Note,  except that a
Lender shall be relieved of its obligations to the extent of any such Assignment
of all or any part of its  Loans,  its  Commitments  or its  Notes  pursuant  to
Section 11.7(c).

11.8 Indemnity

     Each Borrower agrees, to defend, protect,  indemnify, and hold harmless the
Agent,  the  Issuing  Bank  and  each  and all of the  Lenders,  each  of  their
respective Affiliates and each of the respective officers, directors,  employees
and  agents  of  each  of the  foregoing  (each  an  "Indemnified  Person"  and,
collectively,   the  "Indemnified   Persons")  from  and  against  any  and  all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims,  costs,  expenses  and  disbursements  of any kind or nature  whatsoever
(including the fees and disbursements of counsel to such Indemnified Persons) in
connection  with  any  investigative,  administrative  or  judicial  proceeding,
whether  direct,  indirect or  consequential  and whether  based on any federal,

<PAGE>

state or provincial laws or other statutory  regulations,  including  securities
and commercial laws and regulations,  under common law or at equitable cause, or
on  contract  or   otherwise,   including  any   liabilities   and  costs  under
environmental laws, Federal,  state,  provincial or local health or safety laws,
regulations,  or common law  principles,  arising from or in connection with the
past,  present or future operations of any Borrower,  any other Credit Party, or
their  respective  predecessors  in  interest,  or the past,  present  or future
environmental  condition  of the  Property  of  any  Borrower  or  any of  their
Subsidiaries,   the  presence  of  asbestos-containing  materials  at  any  such
Property,  or the release or threatened  release of any Hazardous  Substance (as
defined under applicable  environmental  law) into the environment from any such
Property) in any manner  relating to or arising out of the Loan  Documents,  any
commitment letter or fee letter executed and delivered by any Borrower or any of
its Subsidiaries,  the Issuing Bank and/or the Agent, the  capitalization of any
Borrower  or any of its  Subsidiaries,  the  Commitments,  the  Letter of Credit
Commitment,  the making of, issuance of,  management of and participation in the
Loans or the  Letters of Credit,  or the use or  intended  use of the Letters of
Credit and the proceeds of the Loans hereunder,  provided that no Borrower shall
have any obligation under this Section to an Indemnified  Person with respect to
any of the  foregoing to the extent found in a final  judgment of a court having
jurisdiction to have resulted  primarily out of the gross  negligence or willful
misconduct of such Indemnified  Person or arising solely from claims between one
such Indemnified  Person and another such Indemnified  Person. The indemnity set
forth herein shall be in addition to any other  obligations  or  liabilities  of
either or both Borrowers to each Indemnified  Person under the Loan Documents or
at common  law or  otherwise,  and shall  survive  any  termination  of the Loan
Documents,  the expiration of the Commitments of all of the Lenders,  the Letter
of Credit  Commitment and the payment of all  Indebtedness of the Credit Parties
under the Loan Documents.

11.9 Limitation of Liability

     No claim may be made by any Borrower,  any other Credit  Party,  any of its
Subsidiaries,  any Lender or other Person against the Agent, any Lender,  or any
directors,  officers,  employees,  or  agents  of any of them  for any  special,
indirect,  consequential  or punitive damages in respect of any claim for breach
of contract or any other  theory of  liability  arising out of or related to the
transactions  contemplated by any Loan Document,  or any act,  omission or event
occurring in connection therewith,  and each of each Borrower, its Subsidiaries,
such other Credit Party, any such Lender or other Person hereby waives, releases
and  agrees  not to sue upon any  claim  for any such  damages,  whether  or not
accrued and whether or not known or suspected to exist in its favor.

11.10 Counterparts

     Each Loan Document (other than the Notes) may be executed by one or more of
the  parties  thereto on any  number of  separate  counterparts  and all of said

<PAGE>

counterparts  taken  together  shall be  deemed to  constitute  one and the same
document.  It shall not be  necessary  in making  proof of any Loan  Document to
produce  or  account  for more  than one  counterpart  signed by the party to be
charged. A counterpart of any Loan Document or to any document  evidencing,  and
of any an amendment,  modification, consent or waiver to or of any Loan Document
transmitted  by  telecopy   shall  be  deemed  to  be  an  originally   executed
counterpart. A set of the copies of the Loan Documents signed by all the parties
thereto shall be deposited  with each of the  Borrowers,  the Issuing Bank,  the
Agent and the Lenders. Any party to a Loan Document may rely upon the signatures
of any other party thereto which are transmitted by telecopy or other electronic
means to the same extent as if originally signed.

11.11    Adjustments; Set-off

     (a) If any Lender (a "Benefited  Parent Lender"),  shall obtain any payment
(whether voluntary,  involuntary,  through the exercise of any right of set-off,
or  otherwise) on account of its Revolving  Credit Loans,  its Revolving  Credit
Notes or the  Reimbursement  Obligations  in  excess of its  Parent  Outstanding
Percentage of payments  then due and payable on account of the Revolving  Credit
Loans, the Revolving Credit Notes and the Reimbursement  Obligations received by
all the Lenders,  then such Benefited  Parent Lender shall  forthwith  purchase,
without recourse,  for cash, from the other Lenders such participations in their
Revolving Credit Loans and Revolving Credit Notes as shall be necessary to cause
such  Benefited  Parent  Lender to share such excess  payment  with each of them
according to their Parent Outstanding  Percentages,  provided,  however, that if
all or any  portion of such excess  payment is  thereafter  recovered  from such
Benefited  Parent  Lender,  such  purchase  from  such  other  Lenders  shall be
rescinded,  and each such other  Lender  shall  repay to such  Benefited  Parent
Lender the  purchase  price to the  extent of such  recovery,  together  with an
amount equal to such other Lender's pro rata share  (according to the proportion
of (i) the amount of such other  Lender's  required  repayment to (ii) the total
amount so recovered from such Benefited  Parent Lender) of any interest or other
amount paid or payable by such  Benefited  Parent Lender in respect of the total
amount so recovered.  Each Borrower agrees that such Benefited  Parent Lender so
purchasing a participation  from such other Lenders  pursuant to this subsection
(a) may exercise  such rights to payment  (including  the right of set-off) with
respect to such  participation as fully as such Benefited Parent Lender were the
direct creditor of such Parent in the amount of such participation.

     (b) If any  Lender (a  "Benefited  GP Canada  Lender"),  shall  obtain  any
payment (whether  voluntary,  involuntary,  through the exercise of any right of
set-off, or otherwise) on account of its Term Loans, or its Term Notes in excess
of its GP Canada  Outstanding  Percentage  of  payments  then due and payable on
account of the Term Loans or the Term Notes  received by all the  Lenders,  then
such Benefited GP Canada Lender shall forthwith purchase,  without recourse, for
cash,  from the other  Lenders  such  participations  in their Term Loans and GP

<PAGE>

Canada  Revolving  Credit Notes as shall be necessary to cause such Benefited GP
Canada Lender to share such excess  payment with each of them according to their
GP Canada Outstanding Percentages, provided, however, that if all or any portion
of such excess  payment is thereafter  recovered  from such  Benefited GP Canada
Lender, such purchase from such other Lenders shall be rescinded,  and each such
other Lender shall repay to such  Benefited GP Canada Lender the purchase  price
to the  extent of such  recovery,  together  with an amount  equal to such other
Lender's pro rata share  (according to the  proportion of (i) the amount of such
other  Lender's  required  repayment to (ii) the total amount so recovered  from
such Benefited GP Canada Lender) of any interest or other amount paid or payable
by such  Benefited GP Canada Lender in respect of the total amount so recovered.
Each  Borrower  agrees that such  Benefited  GP Canada  Lender so  purchasing  a
participation  from such  other  Lenders  pursuant  to this  subsection  (a) may
exercise such rights to payment (including the right of set-off) with respect to
such  participation  as fully as such Benefited GP Canada Lender were the direct
creditor of GP Canada in the amount of such participation.

     (c) In  addition to any rights and  remedies  of the  Issuing  Bank and the
Lenders  provided  by law,  upon the  occurrence  of an Event of Default and the
acceleration of the obligations owing in connection with the Loan Documents,  or
at any time  upon the  occurrence  and  during  the  continuance  of an Event of
Default,  under Sections 9.1(a) or (b), each of the Issuing Bank and the Lenders
shall have the right,  without  prior notice to any Borrower or any other Credit
Party,  any such notice being  expressly  waived by each Borrower and each other
Credit  Party to the extent not  prohibited  by  applicable  law, to set-off and
apply against any indebtedness, whether matured or unmatured, of any Borrower or
such other Credit Party, as the case may be, to the Issuing Bank or such Lender,
as the case may be, any amount owing from the Issuing  Bank or such  Lender,  as
the case may be, to any Borrower or such other Credit Party, as the case may be,
at, or at any time after, the happening of any of the above-  mentioned  events.
To the extent not prohibited by applicable  law, the aforesaid  right of set-off
may be exercised by the Issuing Bank or such Lender, as the case may be, against
any  Borrower  or such other  Credit  Party,  as the case may be, or against any
trustee in bankruptcy, custodian, debtor in possession, assignee for the benefit
of creditors,  receiver,  or execution,  judgment or attachment  creditor of any
Borrower or such other Credit Party,  as the case may be, or against anyone else
claiming through or against any Borrower or such other Credit Party, as the case
may be, or such trustee in bankruptcy, custodian, debtor in possession, assignee
for the benefit of creditors,  receiver,  or  execution,  judgment or attachment
creditor,  notwithstanding  the fact that such right of  set-off  shall not have
been exercised by the Issuing Bank or such Lender,  as the case may be, prior to
the making, filing or issuance, or service upon the Issuing Bank or such Lender,
as the case may be, of, or of notice of, any such  petition,  assignment for the
benefit of  creditors,  appointment  or  application  for the  appointment  of a
receiver,  or issuance of  execution,  subpoena,  order or warrant.  Each of the
Issuing Bank and the Lenders agrees  promptly to notify a Borrower and the Agent
after any such set-off and application  made by the Issuing Bank or such Lender,
as the case may be,  provided  that the  failure to give such  notice  shall not
affect the validity of such set-off and application.

11.21 Treatment of Certain Information

     Each  of  the  Issuing  Bank  and  Lenders  understands  that  some  of the
information  furnished to it pursuant to this Loan  Agreement may be received by
it prior to the time that such information shall have been made public, and each
of the Issuing Bank and Lenders  hereby agree that it will keep, and will direct
its officers and employees to keep, all the information  provided to it pursuant
to this  Loan  Agreement  confidential  prior to its  becoming  public  (through
publication  other  than as a result of action  by  Issuing  Bank and one of the
Lenders in violation of this Section 11.21) subject,  however, to (i) disclosure
to  officers,   directors,   employees,   representatives,   agents,   auditors,
consultants,  advisors,  lawyers  and  affiliates  of the  Issuing  Bank or such
Lender,  in the ordinary  course of business,  (ii) disclosure to such officers,
directors,  employees,  agents and representatives of a prospective  assignee or
participant as need to know such  information in connection  with the evaluation
of a possible  participation in the Commitments  hereunder (who will be informed
of the  confidential  nature  of the  material);  (iii) the  obligations  of the
Issuing Bank and Lenders or a participant  under  applicable law, or pursuant to
subpoenas or other legal process, to make information  available to governmental
agencies  and  examiners  or to  others  and the right of the  Issuing  Bank and
Lenders to use such  information  in  proceedings  to enforce  their  rights and
remedies hereunder or under any other Loan Document or in any proceeding against
the Issuing Bank and lenders in connection with this Loan Agreement or under any
other Loan Document or the transactions  contemplated hereunder; (iv) disclosure
to the extent such  information (A) becomes  publicly  available other than as a
result  of a breach of this  Loan  Agreement  or (B)  becomes  available  to the
Issuing Bank or Lender or a  participant  on a  non-confidential  basis,  not in
breach of any agreement or other  obligation to the Parent,  from a source other
than the Parent; (v) disclosure to the extent the Parent shall have consented to
such  disclosure  in  writing;  or (vi)  the  Issuing  Bank or  each  Lender  or
participant's  right  to  make  information  available  (A) to  any  corporation
controlled by the Issuing Bank or Lender or  participant or under common control
with the Issuing Bank or Lender or participant in connection  with the sale of a
participation by such Lender or participant to such other  corporation  provided
such transferee agrees to be bound by  confidentiality or (B) in accordance with
Section 11.21.

11.22 Judgment Currency

     (a) If,  for  the  purposes  of  obtaining  judgment  in any  court,  it is
necessary  to  convert  a sum due to a Lender  in any  currency  (the  "Original
Currency") into another currency (the "Other  Currency"),  the parties agree, to
the fullest  extent that they may  effectively  do so, that the rate of exchange
used shall be that at which, in accordance with normal banking procedures,  such
Lender  could  purchase  the Original  Currency  with the Other  Currency on the
Business Day preceding the day on which final judgment is given or, if permitted
by applicable law, on the day on which the judgment is paid or satisfied.


<PAGE>

     (b) The  obligations  of the  Borrowers  in  respect  of any sum due in the
Original  Currency  from it to a Lender under any of the Loan  Documents  shall,
notwithstanding  any judgment in any Other  Currency,  be discharged only to the
extent  that on the  Business  Day  following  receipt  by the Lender of any sum
adjudged to be so due in the Other Currency,  the Lender may, in accordance with
normal  banking  procedures,  purchase  the  Original  Currency  with such Other
Currency.  If the amount of the Original  Currency so purchased is less than the
sum  originally  due to the  Lender in the  Original  Currency,  the  applicable
Borrower agrees, as a separate obligation and  notwithstanding the judgment,  to
indemnify  the  Lender,  against any loss,  and,  if the amount of the  Original
Currency  so  purchased  exceeds  the sum  originally  due to the  Lender in the
Original Currency, the Lender shall remit such excess to such Borrower.

11.23 Pledge to Federal Reserve

     Any Bank may at any time pledge all or any portion of its rights  under the
Loan  Documents  including  any portion of any Note  payable to it to any of the
twelve (12)  Federal  Reserve  Banks  organized  under  Section 4 of the Federal
Reserve Act, 12 U.S.C.  Section 341. No such pledge or enforcement thereof shall
release any such Bank from its obligations under any of the Loan Documents.

11.24 Lost Notes

     Upon  receipt  of an  affidavit  of an  officer of any Bank as to the loss,
theft,  destruction  or  mutilation of any Note or any other  security  document
which  is not of  public  record,  and,  in the case of any  such  loss,  theft,
destruction or mutilation, upon surrender and cancellation of such Note or other
Collateral  Document,  the applicable  Borrower will issue,  in lieu thereof,  a
replacement  Note or other  Collateral  Document  in the same  principal  amount
thereof and otherwise of like tenor.

11.25  Interest Adjustment

     All agreements between the Credit Parties and the Agent and the Lenders are
hereby expressly limited so that in no contingency or event whatsoever,  whether
by reason of acceleration of maturity of the  indebtedness  evidenced  hereby or
otherwise, shall the amount paid or agreed to be paid to the Lenders for the use
or the forbearance of the indebtedness evidenced by the Notes exceed the maximum
permissible  under  applicable law. As used herein,  the term  "applicable  law"
shall mean the law in effect as of the date hereof  provided,  however,  that in
the event  there is a change in the law which  results  in a higher  permissible
rate of interest,  then the Loan Documents  shall be governed by such new law as
of its  effective  date. In this regard,  it is expressly  agreed that it is the
intent  of the  Credit  Parties,  the Agent and the  Lenders  in the  execution,
delivery and acceptance of this Agreement to contract in strict  compliance with
the laws of the State of New York from time to time in effect. If, under or from
any circumstances  whatsoever,  fulfillment of any provision hereof or of any of
the Loan Documents at the time of  performance  of such provision  shall be due,
shall involve  transcending the limit of such validity  prescribed by applicable
law, then the obligation to be fulfilled shall  automatically  be reduced to the

<PAGE>

limits of such validity,  and if under or from any circumstances  whatsoever the
Lenders should ever receive as interest an amount which would exceed the highest
lawful rate,  such amount which would be excessive  interest shall be applied to
the  reduction of the principal  balance  evidenced by a Note (in such manner as
the Lenders may  determine in their sole  discretion)  and not to the payment of
interest;  provided that, subject to Section 2.2(c) hereof,  with respect to the
GP Canada  Obligations,  same shall be applied,  or shall be deemed to have been
applied as a prepayment of the Term Loans of such Lender.  This provision  shall
control every other  provision of all agreements  between the Credit Parties and
the Agent and the Lenders.

11.26 No Set-off or Counterclaim; Loan Documents in Full Effect

     Each Borrower hereby acknowledges,  confirms and declares that (i) all sums
owing to the Agent and/or the Lenders in connection  with the Loan Documents are
owed without offset, deduction, counterclaim or defense of any kind or nature to
the  payment  thereof  and (ii) the Loan  Documents  and the Liens and  security
interests  created  thereby  are  valid,  subsisting  and,  to  each  Borrower's
knowledge, perfected liens and security interests.

11.27 Obligations Unimpaired; Amendment and Restatement

     (a) GP Canada hereby acknowledges,  confirms and declares that its Borrower
Security  Agreement  remains in full force and effect and is  unimpaired  by the
transactions  contemplated  by this  Agreement and the Liens created  thereunder
remain first priority perfected Liens, unimpaired and undischarged.

     (b) This  Agreement  amends and  restates the  Original  Agreement  and all
indebtedness,  liabilities, Obligations, Liens and security interests arising or
created under the Loan  Documents  continue in full force and effect  (except as
expressly  heretofore  modified  and/or  modified and/or amended and restated in
connection with the transactions contemplated by this Agreement), unimpaired and
undischarged.  This  Agreement is a  replacement,  consolidation,  amendment and
restatement of the Original Agreement and IS NOT A NOVATION.
