II.      THE CREDIT

         2.1.     Revolving Credit Loans.

                  (a) Subject to the terms and conditions hereof and in reliance
upon the representations, warranties and covenants contained herein, each Bank
agrees, severally and not jointly with the other Banks, to make revolving credit
loans (collectively called the "Revolving Credit Loans" and each individually a
"Revolving Credit Loan") to the Borrowers from time to time during the period
commencing on the Closing Date and ending three (3) years following the Closing
Date, or on any earlier date as provided in Section 2.6(b) or Section 8.1 hereof
(the "Revolver Termination Date"), in principal amounts not to exceed at any
time outstanding in the aggregate the amount set forth opposite the name of each
such Bank on the signature page hereof (each such amount being hereinafter
called such Bank's "Revolving Loan Commitment" and collectively, the Banks'
"Aggregate Revolving Loan Commitment"). All Loans shall be made by the Banks
simultaneously and pro rata in accordance with the Revolving Loan Commitments.
The failure of any one or more of the Banks to make Revolving Credit Loans in
accordance with its or their obligations shall not relieve the other Banks of
their several obligations under this Section 2.1(a), but in no event shall the
aggregate amount at any one time outstanding which any Bank shall be required to
lend under this Section 2.1 (a) exceed the amount of such Bank's Revolving Loan
Commitment at that time.

                  (b) The Borrowers may request Revolving Credit Loans to bear
interest at either the Prime Rate or LIBO Rate options described in Section 2.4.
The Revolving Credit Loans outstanding at any one time may involve any
combination of such interest rate options in such amounts as the Borrowers may
determine, subject to the terms and conditions hereof, including the requirement
concerning minimum Loan requests and the requirements that (i) no request may be
made which would require more than one interest rate option or more than one
Interest Period to apply to a single Revolving Credit Loan, and (ii) in the case
of LIBO Rate Loans, no LIBO Rate Loan may have an Interest Period extending
beyond the Revolver Termination Date.

                  (c) Notwithstanding the foregoing, the Borrowers shall not be
entitled to a Revolving Credit Loan if, after giving effect to such Revolving
Credit Loan, the unpaid principal amount of the Revolving Credit Loans to the
Borrowers exceeds the Aggregate Revolving Loan Commitment.

                  (d) Except for Revolving Credit Loans which exhaust the full
remaining amount of the Aggregate Revolving Loan Commitment and conversions
which result in the conversion of all Revolving Credit Loans subject to a
particular interest rate option, each of which may be in lesser amounts, each
Loan when made and each conversion of Loans of one type into Loans of another
type hereunder shall be in an amount at least equal to $500,000 or, if greater,
then in such minimum amount plus $100,000 multiples.

                                       8
<PAGE>

                  (e) Within the limits of the Aggregate Revolving Loan
Commitment, the Borrowers may borrow, prepay (in accordance with Section 2.7)
and reborrow Revolving Credit Loans. All Revolving Credit Loans shall, in any
event, be repaid by the Borrowers on the Revolver Termination Date.

                  (f) If any principal of a LIBO Rate Loan shall be voluntarily
repaid (whether upon prepayment, reduction of the Aggregate Revolving Loan
Commitment after acceleration or for any other reason) or converted to a Prime
Rate Loan pursuant to Section 2.10 prior to the last day of the Interest Period
applicable to such LIBO Rate Loan or if the Borrowers fail for any reason to
borrow a LIBO Rate Loan after giving irrevocable notice pursuant to Section 2.3,
the Borrowers shall pay to each Bank, in addition to the principal and interest
then to be paid, such additional amounts as may be necessary to compensate each
Bank for all appropriate direct and indirect costs and losses (including losses
resulting from redeployment of prepaid or unborrowed funds at rates lower than
the cost of such funds to such Bank, and including lost profits incurred or
sustained by such Bank) as a result of such repayment or failure to borrow (the
"Additional Amount"). The Additional Amount (which each Bank shall take
reasonable measures to minimize) shall be specified in a written notice or
certificate delivered to the Borrowers by the Agent in the form provided by each
Bank sustaining such costs or losses. Such notice or certificate shall contain a
calculation in reasonable detail of the Additional Amount to be compensated and
shall be conclusive as to the facts and the amounts stated therein, absent
manifest error.

         2.2. The Revolving Credit Notes. The Revolving Credit Loans made by
each Bank shall all be evidenced by a single promissory note of the Borrowers
(each such promissory note as it may be amended, extended, modified or renewed a
"Revolving Credit Note") in principal face amount equal to such Bank's Revolving
Loan Commitment, payable to the order of such Bank and otherwise in form and
substance satisfactory to the Banks. The Revolving Credit Notes shall be dated
the Closing Date, shall bear interest at the rate per annum and be payable as to
principal and interest in accordance with the terms hereof. The Revolving Credit
Notes shall mature upon the Revolver Termination Date, and upon maturity each
outstanding Revolving Credit Loan evidenced thereby shall be due and payable.
The Agent shall maintain records of all Loans evidenced by the Revolving Credit
Notes and of all payments thereon, which records shall be conclusive absent
manifest error.

         2.3.     Funding Procedures.

                  (a) Each request for a Revolving Credit Loan or the conversion
or renewal of an interest rate with respect to a Loan shall be made not later
than 1l:00 a.m. on a Business Day by delivery to the Agent of a written request
signed by IGC on behalf of the Borrowers or, in the alternative, a telephone
request followed promptly by written confirmation of the request, specifying the
date and amount of the Loan to be made, converted or renewed, selecting the
interest rate option applicable thereto, and in the case of LIBO Rate Loans,
specifying the Interest Period applicable to such Loan. The form of request
attached hereto as Exhibit A ("Borrowing Notice") shall be used to request the
making, conversion or renewal of Revolving Credit Loans unless otherwise agreed.
Each request shall be received not less than one (1) Business Day prior to the
date of the proposed borrowing, conversion or renewal in the case of Prime Rate
Loans, and three (3) London Business Days prior to the date of the proposed
borrowing, conversion or renewal in the case of LIBO Rate Loans. No request
shall be effective until actually received in writing by the Agent.

<PAGE>

                  (b) Upon receipt of a request for a Loan or the conversion of
a Loan, and if the conditions precedent provided herein shall be satisfied at
the time of such request the Agent promptly shall notify each Bank of such
request and of such Bank's ratable share of such Loan. Upon receipt by the Agent
the request for a Loan or the conversion of a Loan shall not be revocable by the
Borrowers.

                  (c) Not later than 11:00 A.M. on the date of each Loan, each
Bank shall make available (except as provided in clause (d) below) its ratable
share of such Loan, in immediately available funds, to the Agent at the address
set forth in Section 12.6 hereof or at such account in London as the Agent shall
specify to the Borrowers and the Banks. Unless the Agent knows that any
applicable condition specified herein has not been satisfied, the Agent will
make the funds so received from the Banks immediately available to the Borrowers
on the date of each Loan by a credit to the account of the Borrowers at the
Agent's aforesaid address.

                  (d) Unless the Agent shall have been notified by any Bank at
least one (1) Business Day prior to the date of the making, conversion or
renewal of any LIBO Rate Loan, or by 3:00 P.M. on the date a Prime Rate Loan is
requested, that such Bank does not intend to make available to the Agent such
Bank's portion of the total amount of the Loan to be made, converted or renewed
on such date, the Agent may assume that such Bank has made such amount available
to the Agent on the date of the Loan and the Agent may, in reliance upon such
assumption, make available to the Borrowers a corresponding amount. If and to
the extent such Bank shall not have made such funds available to the Agent, such
Bank agrees to repay the Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrowers until the date such amount is repaid to the Agent, at
the Federal Funds Rate plus 50 basis points. If such Bank shall repay to the
Agent such corresponding amount such amounts so repaid shall constitute such
Bank's Loan for purposes of this Agreement. If such Bank does not repay such
corresponding amount forthwith upon the Agent's demand therefor, the Agent shall
promptly notify the Borrowers, and the Borrowers shall within sixty (60) days of
such notice pay such corresponding amount to the Agent, without any prepayment
penalty or premium, but with interest on the amount repaid, for each day from
the date such amount is made available to the Borrowers until the date such
amount is repaid to the Agent, at the rate of interest applicable at the time to
such Loan. Nothing herein shall be deemed to relieve any Bank of its obligation
to fulfill its Revolving Loan Commitment hereunder or to prejudice any rights
which the Borrowers may have against any Bank as a result of any default by such
Bank hereunder.

                  (e) If the Banks make a Loan on a day on which all or any part
of an outstanding Loan from the Banks is to be repaid, each Bank shall apply the
proceeds of its new Loan to make such repayment and only an amount equal to the
difference (if any) between the amount being borrowed and the amount being
repaid shall be made available by such Bank to the Agent as provided in
clause (c).

         2.4.     Interest.

                  (a) Prime Rate. Each Prime Rate Loan shall bear interest on
the principal amount thereof from the date made until such Loan is paid in full
or converted, at a rate per annum equal to the Prime Rate plus the Applicable
Margin determined from time to time.

                  (b) LIBO Rate. Each LIBO Rate Loan shall bear interest on the
principal amount thereof from the date made until such Loan is paid in full,
renewed, or converted, at a rate per annum equal to the applicable LIBO Rate
plus the Applicable Margin determined from time to time.

                           (1) After receipt of a request for a LIBO Rate Loan,
         the Agent shall proceed to determine the LIBO Rate to be applicable
         thereto. The Agent shall give prompt notice by telephone or facsimile
         to the Borrowers and to each Bank of the LIBO Rate thus determined in
         respect of each LIBO Rate Loan or any change therein.

                           (2) In the event the Borrowers fail to, or are not
         permitted to, select an Interest Period for any LIBO Rate Loan within
         the time period and otherwise as provided herein, such Loan shall be
         automatically converted into a Prime Rate Loan on the last day of the
         Interest Period for such Loan.

                  (c)      Intentionally Omitted.

                  (d) Renewals and Conversions of Loans. The Borrowers shall
have the right to convert Prime Rate Loans into LIBO Rate Loans, and vice versa,
and to renew LIBO Rate Loans from time to time, provided that: (i) IGC, on
behalf of the Borrowers, shall give the Agent notice of each permitted
conversion or renewal as provided in Section 2.3 hereof; (ii) upon receipt by
Agent of any notice contemplated by (i) of this Section 2.4(d), Agent shall
promptly give the Banks notice thereof, (iii) LIBO Rate Loans may be converted
or renewed only as of the last day of the applicable Interest Period for such
Loans; and (iv) no Interest Period may be renewed if on the proposed date of
conversion an Event of Default, or Potential Default exists or would thereby
occur. The Agent shall use its best efforts to notify the Borrowers of the
effectiveness of each such conversion or renewal, and the new interest rate
to-which the converted or renewed Loan is subject, as soon as practicable after
the conversion; provided, however, that any failure to give such notice shall
not affect the Borrowers' obligations or the Banks' rights and remedies
hereunder in any way whatsoever.

                  (e) Continuing Liability of Borrowers. The liability of the
Borrowers under this Section 2.4 shall continue to be effective or be
automatically reinstated, as the case may be, if at any time payment, in whole
or in part, of any of the payments to the Banks is rescinded or must otherwise
be restored or returned upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of any Borrower or any other Person, or upon or as
a result of the appointment of a custodian receiver, trustee or other officer
with similar powers with respect to any Borrower or other Person or any
substantial part of its property, or otherwise, all as though such payment had
not been made.

<PAGE>

         2.5.     Fees.

                  The Borrowers shall pay to the Agent for the ratable benefit
of the Banks, and as compensation for the Banks' Revolving Loan Commitments, a
fee (the "Commitment Fee") computed at the rate per annum equal to 15 basis
points (0.15%) on the average daily amount of the Aggregate Revolving Loan
Commitment accrued from and after the date hereof. The Commitment Fee shall be
payable in arrears on the first day of each January, April, July and October,
commencing October 1, 2001 (for the three month period or portion thereof ended
on the preceding day), and on the Revolver Termination Date. Payment shall be
made to the Agent on behalf of the Banks and the Agent shall promptly forward to
each Bank the portion of the Commitment Fee amount due such Bank. The Commitment
Fee shall be calculated on the basis of a 360 day year.

         2.6. Reduction or Termination of Aggregate Revolving Loan Commitment.

                  (a) Voluntary. The Borrowers may at any time, on not less than
three (3) Business Days' written notice, terminate or permanently reduce the
Aggregate Revolving Loan Commitment pro rata among the Banks, provided that any
reduction shall be in the amount of $1,000,000 a multiple thereof and that no
such reduction shall cause the principal amount of Loans outstanding to exceed
the Aggregate Revolving Credit Commitment as reduced.

                  (b) Termination. In the event the Aggregate Revolving Loan
Commitment is terminated pursuant to the terms of this Agreement, the Revolver
Termination Date shall accelerate and the Borrowers shall, simultaneously with
such termination, repay the Prime Rate Loans and LIBO Rate Loans in accordance
with Section 2.8.

         2.7.     Voluntary Prepayments.

                  (a) Prime Rate Loans: On one (1) Business Day's notice to the
Banks, the Borrowers may, at their option, prepay the Prime Rate Loans in whole
at any time or in part from time to time, provided that each partial prepayment
shall be in the principal amount of $500,000 or, if greater, then in $100,000
multiples.

                  (b) LIBO Rate Loans. The Borrowers may, at their option,
prepay any LIBO Rate Loan, provided that if the Borrowers shall prepay a LIBO
Rate Loan prior to the last day of the applicable Interest Period, or shall fail
to borrow any LIBO Rate Loan on the date such Loan is to be made, the Borrowers
shall pay to each Bank, in addition to the principal and interest then to be
paid in the case of a prepayment, on such date of prepayment, the Additional
Amount incurred or sustained by such Bank as a result of such prepayment or
failure to borrow as provided in Section 2.1(f)).

         2.8.     Payments.

                  (a) LIBO Rate Loans. Accrued interest on LIBO Rate Loans with
Interest Periods of one, two or three months shall be due and payable on the
last day of such Interest Period. Accrued interest on LIBO Rate Loans with
Interest Periods of six months shall be due and payable at the end of the third
month and on the last day of such Interest Period.

                                       12
<PAGE>

                  (b) Prime Rate Loans. Accrued interest on all Prime Rate Loans
shall be due and payable on the first Business Day of each month and upon the
Revolver Termination Date.

                  (c) Form of Payments; Application of Payments; Payment
Administration, Etc. Provided that no Event of Default or Potential Default then
exists, all payments and prepayments shall be applied to the Loans in such order
and to such extent as shall be specified by the Borrowers, by written notice to
the Agent at the time of such payment or prepayment. Except as otherwise
provided herein, all payments of principal, interest, fees, or other amounts
payable by the Borrowers hereunder shall be remitted to the Agent on behalf of
the Banks at the address set forth opposite its name on the signature page
hereof or at such office or account as the Agent shall specify to the Borrowers
and the Banks, in immediately available funds not later than 12:00 p.m. on the
day when due. If any payment is made by the Borrowers pursuant to the previous
sentence and is received by the Agent (i) at or prior to 12:00 p.m. on any
Business Day, then on that same Business Day the Agent shall distribute to each
Bank by wire transfer in immediately available funds each Bank's pro rata share
of such payment based upon such Bank's Commitment Percentage or (ii) later than
12:00 p.m. on any Business Day, then on the immediately following Business Day
the Agent shall distribute to each Bank by wire transfer in immediately
available funds each Bank's pro rata share of such payment based upon such
Bank's Commitment Percentage. Whenever any payment is stated as due on a day
which is not a Business Day, the maturity of such payment shall, except as
otherwise provided in the definition of "Interest Period" in Section 1.1, be
extended to the next succeeding Business Day and interest and commitment fees
shall continue to accrue during such extension. Each Borrower authorizes the
Agent to deduct from any account of any Borrower maintained at the Agent or over
which the Agent has control any amount payable under this Agreement, the Notes
or any other Loan Document which is not paid in a timely manner. The Agent's
failure to deliver any bill, statement or invoice with respect to amounts due
under this Section or under any Loan Document shall not affect the Borrowers'
obligations to pay any installment of principal, interest or any other amount
under this Agreement when due and payable.

                  (d) Net Payments. All payments made to the Banks and the Agent
by the Borrowers hereunder, under any Note or under any other Loan Document will
be made without set-off, counterclaim or other defense. All such payments will
be made free and clear of, and without deduction or withholding for, any taxes,
assessments or other charges lawfully levied or assessed upon any Borrower,
including, without limitation, real and personal property taxes, assessments and
charges and all franchise, income, employment, social security benefits,
withholding and sales taxes, each of which shall be paid, when due and as
applicable, by each Borrower. If any tax by any governmental authority is or may
be imposed on or as a result of any transaction between any Borrower and Agent
or any Bank which Agent or any Bank may be required to withhold or pay or if any
taxes, assessments, or other charges remain unpaid after the date fixed for
their payment, Agent may without notice to Borrowers pay the taxes, assessments
or other charges and each Borrower hereby indemnifies and holds Agent and each
Bank harmless in respect thereof. Agent will not pay any taxes, assessments or
charges to the extent that any Borrower has contested or disputed those taxes,
assessments or charges in good faith, by expeditious protest, administrative or
judicial appeal or similar proceeding provided that any related tax lien is
stayed. The amount of any payment by Agent under this Section 2.8(d) shall be
charged to Borrowers as a Revolving Credit Loan and added to the Obligations
and, until Borrowers shall furnish Agent with an indemnity therefor (or supply
Agent with evidence satisfactory to Agent that due provision for the payment
thereof has been made), Agent may hold without interest any balance standing to
Borrowers' credit.

         2.9.     Changes in Circumstances: Yield Protection.

                  (a) If any Regulatory Change or compliance by the Banks with
any request made after the date of this Agreement by the Board of Governors of
the Federal Reserve System or by any Federal Reserve Bank or other central bank
or fiscal, monetary or similar authority (in each case whether or not having the
force of law) shall:

                           (i) impose, modify or make applicable any reserve,
                  special deposit, Federal Deposit Insurance Corporation premium
                  or similar requirement or imposition against assets held by,
                  or deposits in or for the account of, or loans made by, or any
                  other acquisition of funds for loans or advances by, the
                  Banks;

                           (ii) impose on the Banks any other condition
                  regarding the Notes;

                           (iii) subject the Banks to, or cause the withdrawal
                  or termination of any previously granted exemption with
                  respect to, any tax (including any withholding tax but not
                  including any income tax not currently causing the Banks to be
                  subject to withholding) or any other levy, impost, duty,
                  charge, fee or deduction on or from any payments due from the
                  Borrowers; or

                           (iv) change the basis of taxation of payments from
                  the Borrowers to the Banks (other than by reason of a change
                  in the method of taxation of a Bank's net income);

and the result of any of the foregoing events is to increase the cost to a Bank
of making or maintaining any Loan or to reduce the amount of principal, interest
or fees to be received by the Bank hereunder in respect of any Loan, the Agent
will immediately so notify the Borrowers. If a Bank determines in good faith
that the effects of the change resulting in such increased cost or reduced
amount cannot reasonably be avoided or the cost thereof mitigated, then upon
notice by the Agent to the Borrowers, the Borrowers shall pay to such Bank on
each interest payment date of the Loan, such additional amount as shall be
necessary to compensate the Bank for such increased cost or reduced amount.

                  (b) If any Bank shall reasonably determine that any Regulation
regarding capital adequacy or the adoption of any Regulation regarding capital
adequacy, which Regulation is applicable to banks (or their holding companies)
generally and not such Bank (or its holding company) specifically, or any change
therein, or any change in the interpretation or administration thereof by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by such Bank (or its
holding company) with any such request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has the effect of reducing the rate of return on such Bank's
capital as a consequence of its obligations hereunder to a level below that
which such Bank could have achieved but for such adoption, change or compliance
(taking into consideration such Bank's policies with respect to capital
adequacy) by an amount reasonably deemed by such Bank to be material, the
Borrowers shall promptly pay to the Agent for the account of such Bank upon the
demand of such Bank, such additional amount or amounts as will compensate such
Bank for such reduction.

                                       14
<PAGE>

                  (c) If the Agent shall reasonably determine (which
determination will be made after consultation with any Bank requesting same and
shall be, in the absence of fraud or manifest error, conclusive and binding upon
all parties hereto) that by reason of abnormal circumstances affecting the
interbank eurodollar or applicable eurocurrency market, adequate and reasonable
means do not exist for ascertaining the LIBO Rate to be applicable to the
requested LIBO Rate Loan or that eurodollar or eurocurrency funds in amounts
sufficient to fund all the LIBO Rate Loans are not obtainable on reasonable
terms, the Agent shall give notice of such inability or determination by
telephone to the Borrowers and to each Bank at least two (2) Business Days prior
to the date of the proposed Loan and thereupon the obligations of the Banks to
make, convert other Loans to, or renew such LIBO Rate Loan shall be excused,
subject, however, to the right of the Borrowers at any time thereafter to submit
another request.

                  (d) Determination by a Bank for purposes of this Section 2.9
of the effect of any Regulatory Change or other change or circumstance referred
to above on its costs of making or maintaining Loans or, on amounts receivable
by it in respect of the Loans and of the additional amounts required to
compensate such Bank in respect of any additional costs, shall be made in good
faith and shall be evidenced by a certificate, signed by an officer of such Bank
and delivered to the Borrowers, as to the fact and amount of the increased cost
incurred by or the reduced amount accruing to the Bank owing to such event or
events. Such certificate shall be prepared in reasonable detail and shall be
conclusive as to the facts and amounts stated therein, absent manifest error.

                  (e) The affected Bank will notify the Borrowers of any event
occurring after the date of this Agreement that will entitle the Bank to
compensation pursuant to this Section as promptly as practicable after it
obtains knowledge thereof and determines to request such compensation. Said
notice shall be in writing, shall specify the applicable Section or Sections of
this Agreement to which it relates and shall set forth the amount of amounts
then payable pursuant to this Section. The Borrowers shall pay such Bank the
amount shown as due on such notice within 10 days after their receipt of the
same.

         2.10. Illegality. Notwithstanding any other provision in this
Agreement, if the adoption of any applicable Regulation, or any change therein,
or any change in the interpretation or administration thereof by any
Governmental Authority, central bank, or comparable agency charged with the
interpretation or administration thereof, or compliance by the Banks with any
request or directive (whether or not having the force of law) of any such
authority, central bank, or comparable agency shall make it unlawful or
impossible for the Banks to (1) maintain their Revolving Loan Commitments, then
upon notice to the Borrowers by the Agent, the Revolving Loan Commitments shall
terminate; or (2) maintain or fund their LIBO Rate Loans, then upon notice to
the Borrowers of such event, the Borrowers' outstanding LIBO Rate Loans shall be
converted into Prime Rate Loans.

         2.11. Joint and Several Liability. Each Borrower, on a joint and
several basis, unconditionally and irrevocably guarantees to each Bank the due,
prompt and complete payment by each other Borrower of its payment of principal
of and interest on each Revolving Credit Loan, when and as the same shall become
due and payable, and any and all other amounts with respect to which any other
Borrower is obligated under any Loan Document. The obligation of each Borrower
under this Section 2.11 is a guaranty of payment and not of collectability and
is no way conditioned or contingent upon any attempt to collect from or enforce
compliance by any other Borrower or upon any other event, contingency or
circumstance whatsoever. The obligation of each Borrower under this Section
shall be primary, absolute and unconditional, shall not be subject to any
counterclaim, set-off, deduction, diminution, abatement, recoupment, suspension,
deferment, reduction, or defense based upon any claim any Borrower or any other
Person may have against any other Borrower or any other Person, and shall remain
in full force and effect without regard to, and shall not be released,
discharged or in any way affected by, any circumstance or condition whatsoever
(whether or not any Borrower shall have any knowledge or notice thereof). No
Borrower shall be subrogated to the rights of the Banks in respect of any
payment or other obligation with respect to which an amount has been payable by
such Borrower under this Section 2.11 and no Borrower shall seek to exercise any
rights of subrogation, reimbursement or indemnity arising from payments made by
it pursuant to the provisions of this Section 2.11 until all Obligations have
been paid in full and the Revolving Loan Commitments have been terminated.

         2.12. Optional Cash Management Facility. Should the Borrowers, or any
of them, utilize the cash management services of First Union, the Banks agree to
allow $500,000 of the Revolving Loan Commitment of First Union to be dedicated
to fund, on a daily basis, the cash management requirements of such Borrower(s),
without allocating such borrowings among the Banks on a pro rata basis;
provided, however, the minimum amount to be utilized by such Borrower(s) for
cash management under this Section 2.12 shall be $100,000 and the interest rate
applicable to such amounts shall be the interest rate applicable to Prime Rate
Loans.

III.     REPRESENTATIONS AND WARRANTIES

         In order to induce the Banks to execute and deliver this Agreement and
to make the Loans available to the Borrowers, the Borrowers, jointly and
severally, represent and warrant to the Banks that:

         3.1. Good Standing of the Borrowers: Authorization. Each of the
Borrowers is duly incorporated, validly existing and in good standing in its
jurisdiction of incorporation or formation. Each Borrower is duly qualified as a
foreign corporation or limited liability company and authorized to do business
in all other jurisdictions wherein the nature of its business or property makes
such qualification necessary except where the failure to so qualify would not
have a material adverse effect on the financial condition of such Borrower, and
has the corporate or limited liability company power to own its properties and
to carry on its business as now conducted. The execution, delivery and
performance of this Agreement and the Loan Documents have been duly authorized
by all necessary corporate or limited liability company proceedings on the part
of each of the Borrowers.

                                       16
<PAGE>

         3.2. Compliance with Laws and Other Agreements. Each Borrower is in
compliance in all material respects with all Other Loan Agreements and
Regulations applicable to such Borrower and has not received, and has no
knowledge of, any order or notice of any governmental investigation or of any
violation or claim of violation of any Other Loan Agreement or Regulation that
might have a materially adverse effect on any Borrower.

         3.3. No Conflict: Governmental Approvals. The execution, delivery, and
performance of this Agreement and each of the Loan Documents will not (i)
conflict with, violate, constitute a default under, or result in a breach of any
provision of any applicable law, rule, regulation, judgment decree, order,
instrument or other agreement, or (ii) conflict with or result in a breach of
any provision of the certificate or articles of incorporation or by-laws or
certificate of formation or operating agreement of any Borrower. No
authorization, permit, consent or approval of or other action by, and no filing,
registration or declaration with, any governmental authority or regulatory body
is required to be obtained or made by any Borrower for the due execution and
performance of this Agreement or any of the Loan Documents, except such as have
been duly obtained or made prior to the Closing Date and are in full force and
effect as of the Closing Date (copies of which have been delivered to the Banks
on or before the Closing Date).

         3.4.     Financial and Other Information Regarding Borrowers.

                  (a) The Borrowers have delivered to the Banks true, correct
and complete copies of the consolidated balance sheets of IGC and its
consolidated Subsidiaries as of May 27, 2001, and related statements of income
for the period then ended, together with notes thereto and the unqualified
opinion thereon, dated July 17, 2001, of Pricewaterhouse Coopers LLP. The
Borrowers shall, upon request by the Agent, supply the Banks with true and
correct copies of consolidating balance sheets of IGC and its consolidated
subsidiaries for the aforementioned periods. Those financial statements and the
notes thereto (together, the "Financial Statements") present fairly the
financial position of IGC and its consolidated Subsidiaries as at such dates and
the results of their operations for the periods then ended in conformity with
GAAP.

                  (b) As of the date of this Agreement, no Borrower has any
Indebtedness other than as shown in the Financial Statements.

                  (c) Except as set forth on Schedule 3.4(c) as of the date of
this Agreement no Borrower has any "investment" (as such term is defined under
GAAP), whether by stock purchase, capital contribution, loan, advance, purchase
of property or otherwise, in any Person.

         3.5. Taxes. No Borrower is delinquent in the payment of any material
income, property or other tax, except for any delinquency in the payment of a
tax which is contested in good faith by a Borrower and for which appropriate
reserves have been established in accordance with GAAP.

         3.6.     Liens and Guaranties.

                  (a) All properties and assets of each Borrower are owned by
that Borrower free and clear of all Liens except (i) those for taxes or other
government charges either not yet delinquent or the nonpayment of which is
permitted by Section 3.5 of this Agreement; (ii) those not arising in connection
with Indebtedness that do not materially impair the use or value of the
properties or assets of that Borrower in the conduct of its businesses; (iii)
Liens whose release and termination is evidenced by the Borrowers' delivery to
the Banks of appropriate documents on the Closing Date; and (iv) Liens permitted
under the Loan Documents.

                                       17
<PAGE>

                  (b) Except as permitted hereby, no Borrower is obligated under
any Guaranty.

         3.7. Material Adverse Changes. Since May 27, 2001, there has not been
any material adverse change in the business, operations, properties or financial
position of any of the Borrowers. No Borrower knows of any fact (other than
matters of a general economic or political nature) which materially adversely
affects, or, so far as that Borrower can now reasonably foresee, will materially
adversely affect, the business, operations, properties or financial position of
any Borrower or the performance by any Borrower of its obligations under this
Agreement and the other Loan Documents.

         3.8. Compliance with Federal Reserve Board Regulations. No part of the
proceeds of the Loans will be used, directly or indirectly, for the purpose of
purchasing or carrying any "margin security" within the meaning of Regulation U
of the Board of Governors of the Federal Reserve System (12 C.F.R. 221), or for
the purpose of purchasing or carrying or trading in any securities under such
circumstances as to involve any Borrower in a violation of Regulation X of the
said Board (12 C.F.R. 224). The assets of the Borrowers do not include any
margin securities, and no Borrower has any present intention of acquiring any
margin security.

         3.9. ERISA. The provisions of each Plan maintained by any Borrower
complies in all material respects with all applicable requirements of ERISA and
of the Code, and with all applicable rulings and regulations issued under the
provisions of ERISA and the Code setting forth those requirements. No Reportable
Event has occurred with respect to any Plan; no Plan to which Section 4021 of
ERISA applies has been terminated and no Plan has incurred any liability to PBGC
as provided in Section 4062,4063 and 4064 of ERISA; no Plan has been involved in
any prohibited transaction within the meaning of Section 406 of ERISA or Section
4975 of the Code; and no Termination Event has occurred.

         3.10. Pending Litigation. There are no actions, suits, proceedings or
investigations pending, or, to the knowledge of any of the Borrowers, threatened
against or affecting any Borrower, before any court, arbitrator or
administrative or governmental body which, in the aggregate, might adversely
affect any action taken or to be taken by any Borrower under this Agreement and
the other Loan Documents or which, in the aggregate, might materially adversely
affect the business, operations, properties or financial position of any
Borrower, or the ability of any Borrower to perform its obligations under this
Loan Agreement and the other Loan Documents.

         3.11. Valid, Binding and Enforceable. This Agreement and the Loan
Documents have been duly and validly executed and delivered by the parties
thereto (other than the Banks) and constitute the valid and legally binding
obligations of such parties enforceable in accordance with their respective
terms, except as enforcement of this Agreement, and the Loan Documents may be
limited by bankruptcy, insolvency or other laws of general application relating
to or affecting the enforcement of creditors' rights and except as enforcement
is subject to general equitable principles.

                                       18
<PAGE>

         3.12. No Untrue Statements. To the Borrowers' knowledge, neither this
Agreement, the Loan Documents nor any other document, certificate or statement
furnished or to be furnished by the Borrowers or by any other party to the Banks
in connection herewith contains, or at the time of delivery will contain, any
untrue statement of a material fact or omits or will omit to state a material
fact necessary in order to make the statements contained herein and therein not
misleading.

future laws, ordinances, rules and regulations applicable to them in the
operation of their businesses; provided, however, that a Borrower may terminate
any patent, trademark or license and other rights conferred by jurisdictions
outside the United States as long as such Borrower's business judgment requires
such termination.

requirements of ERISA and of the Code and with all applicable rulings and
regulations issued under the provisions of ERISA and of the Code. As promptly as

receives from the PBGC a notice of intent to terminate any Plan or to appoint a
trustee to administer any Plan, after a Borrower has notified the PBGC that any
Reportable Event has occurred, or after a Borrower has filed a notice of intent
to terminate with the PBGC with respect to any Plan, a certificate of the chief
executive officer of that Borrower shall be furnished to the Agent setting forth
the details with respect to the events resulting in such Reportable Event, as
the case may be, and the action which such Borrower proposes to take with
respect thereto, together with a copy of the notice of intent to terminate or to
appoint a trustee from the PBGC, of the notice of such Reportable Event or of a
Borrower's notice of intent to terminate, as the case may be.

within the period of time (if any) within which such other agreement permits
such default to be remedied, unless such default is waived by the other party
thereto or excused as a matter of law.

enforceability of any material term or provision of any of the Loan Documents is
disputed by, on behalf of, or in the right or name of any Borrower or any
material term or provision of any such Loan Document is found or declared to be
invalid, avoidable, or non-enforceable by any court of competent jurisdiction.

         7.5. False Warranties; Breach of Representations. Any warranty or

Agreement or any other Loan Document or in any certificate or other writing
delivered under or pursuant to this Agreement or any other Loan Document, or in

contemplated hereby shall prove to have been false or incorrect or breached in
any material aspect on the date as of which made.

exceeds One Million Dollars ($1,000,000.00) outstanding at any one time; or (ii)

or enforcement thereof stayed pending appeal, within thirty (30) days after
entry or issuance thereof or, in the event of such a stay, such Judgment is not

VIII.    REMEDIES

         8.1.     Further Advances; Acceleration; Setoff.

                                       27
<PAGE>

                  (a) Upon the occurrence of any one or more Events of Default,
the Agent shall, upon the written request of the Required Banks, terminate the
Revolving Loan Commitments and refuse to make any further advances or Loans to
the Borrowers.

                  (b) Automatically upon the occurrence of any Event of Default
described in Section 7.7 of this Agreement, and in the sole discretion of the
Required Banks upon the occurrence of any other Event of Default, the unpaid
principal balance of all Loans, all interest and fees accrued and unpaid
thereon, and all other amounts and Obligations payable by the Borrowers under
this Agreement and the other Loan Documents shall immediately become due and
payable in full, all without protest, presentment, demand, or further notice of
any kind to the Borrowers, all of which are expressly waived by the Borrowers.

                  (c) If any one or more Events of Default shall have occurred,
the Banks, any affiliate of any Bank and any other participant in the Loans
shall have the right, in addition to all other rights and remedies available to
them, without notice to the Borrowers, to apply toward and set-off against and
apply to the then unpaid balance of the Notes and the other Obligations any
items or funds held by any Bank or any such affiliate or participant, any and
all deposits (whether general or special, time or demand, matured or unmatured,
fixed or contingent, liquidated or unliquidated) now or hereafter maintained by
any Borrower for its own account with any Bank or any such affiliate or
participant, and any other indebtedness at any time held or owing by any Bank or
any such affiliate or participant, to or for the credit or the account of such
Borrowers. For such purpose, the Banks and any such affiliate or participant
shall have, and each Borrower hereby grants to the Banks and any such affiliate
or participant, a first lien on all such deposits. The Banks and any such
affiliate or participant are hereby authorized to charge any such account or
indebtedness for any amounts due to the Banks and any such affiliate or
participant. Such right of set-off shall exist whether or not the Banks shall
have made any demand under this Agreement, the Notes or any other Loan Document
and whether or not the Notes and the other Obligations are matured or unmatured.
Each Borrower hereby confirms the Banks' and any such affiliate's or
participant's lien on such accounts and right of set-off, and nothing in this
Agreement shall be deemed any waiver or prohibition of such lien and right of
set-off.

                  (d) Any date on which the Loans and such other obligations are
declared due and payable pursuant to this Section shall be the Revolver
Termination Date for purposes of this Agreement. Prior to the Revolver
Termination Date, so long as an Event of Default shall have occurred and be
continuing, and at all times after the Revolver Termination Date the Loans shall
bear interest at the Default Rate.

         8.2. Further Remedies. Upon the occurrence of any one or more Events of
Default, the Agent and the Banks may proceed to protect and enforce their rights
under this Agreement and the other Loan Documents by exercising such remedies as
are available to the Agent and the Banks in respect thereof under applicable
law, either by suit in equity or by action at law, or both, whether for specific
performance of any provision contained in this Agreement or any of the other
Loan Documents or in aid of the exercise of any power granted in this Agreement
or any of the other Loan Documents.

IX.      AGENT

         9.1. Appointment and Authorization. Each Bank hereby irrevocably
appoints and authorizes the Agent to take such action on its behalf and to
exercise such powers under this Agreement and the Loan Documents as are
specifically delegated to the Agent by the terms hereof or thereof, together
with such other powers as are reasonably incidental thereto. The relationship
between the Agent and each Bank has no fiduciary aspects, and the Agent's duties
(as Agent) hereunder are acknowledged to be only ministerial and not involving
the exercise of discretion on its part. Nothing in this Agreement or any Loan
Document shall be construed to impose on the Agent any duties or
responsibilities other than those for which express provision is made herein or
therein. In performing its duties and functions hereunder, the Agent does not
assume and shall not be deemed to have assumed, and hereby expressly disclaims,
any obligation with or for the Borrowers. As to matters not expressly provided
for in this Agreement or any Loan Document, the Agent shall not be required to
exercise any discretion or to take any action or communicate any notice, but
shall be fully protected in so acting or refraining from acting upon the
instructions of the Required Banks and their respective successors and assigns;
provided, however, that in no event shall the Agent be required to take any
action which exposes it to personal liability or which is contrary to this
Agreement, any Loan Document or applicable law, and the Agent shall be fully
justified in failing or refusing to take any action hereunder unless it shall
first be specifically indemnified to its satisfaction by the Banks against any
and all liability and expense which may be incurred by it by reason of taking or
omitting to take any such action. If an indemnity furnished to the Agent for any
purpose shall, in the reasonable opinion of the Agent, be insufficient or become
impaired, the Agent may call for additional indemnity from the Banks and not
commence or cease to do the acts for which such indemnity is requested until
such additional indemnity is furnished.

         9.2. Duties and Obligations. In performing its functions and duties
hereunder on behalf of the Banks, the Agent shall exercise the same care and
skill as it would exercise in dealing with loans for its own account. Neither
the Agent nor any of its directors, officers, employees or other agents shall be
liable for any action taken or omitted to be taken by it or them under or in
connection with this Agreement or any Loan Document except for its or their own
gross negligence or willful misconduct. Without limiting the generality of the
foregoing, the Agent (a) may consult with legal counsel and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken by it in good faith and in accordance with the advice of such experts; (b)
makes no representation or warranty to any Bank as to, and shall not be
responsible to any Bank for, any recital, statement, representation or warranty
made in or in connection with this Agreement, any Loan Document or in any
written or oral statement (including a financial or other such statement),
instrument or other document delivered in connection herewith or therewith or
furnished to any Bank by or on behalf of any Borrower, (c) shall have no duty to
ascertain or inquire into any Borrower's performance or observance of any of the
covenants or conditions contained herein or to inspect any of the property
(including the books and records) of any Borrower or inquire into the use of the
proceeds of the Revolving Credit Loans or (unless the officers of the Agent
active in their capacity as officers of the Agent on the Borrowers' account have
actual knowledge thereof or have been notified in writing thereof) to inquire
into the existence or possible existence of any Event of Default or Potential
Default; (d) shall not be responsible to any Bank for the due execution,
legality, validity, enforceability, effectiveness, genuineness, sufficiency,
collectability or value of this Agreement or any other Loan Document or any
instrument or document executed or issued pursuant hereto or in connection
herewith, except to the extent that such may be dependent on the due
authorization and execution by the Agent itself; (e) except as expressly
provided herein in respect of information and data furnished to the Agent for
distribution to the Banks, shall have no duty or responsibility, either
initially or on a continuing basis, to provide to any Bank any credit or other
information with respect to any Borrower, whether coming into its possession
before the making of the Loans or at any time or times thereafter; and (f) shall
incur no liability under or in respect of this Agreement or any other Loan
Document for, and shall be entitled to rely and act upon, any notice, consent,
certificate or other instrument or writing (which may be by facsimile
(telecopier), telegram, cable, or other electronic means) believed by it to be
genuine and correct and to have been signed or sent by the proper party or
parties.

                                       29
<PAGE>

         9.3. The Agent as a Bank. With respect to its Revolving Loan Commitment
and the Loans made and to be made by it, the Agent shall have the same rights
and powers under this Agreement and all other Loan Documents as the other Banks
and may exercise the same as if it were not the Agent. The terms "Bank" and
"Banks" as used herein shall, unless otherwise expressly indicated, include the
Agent in its individual capacity. The Agent and any successor Agent which is a
commercial bank, and their respective affiliates, may accept deposits from, lend
money to, act as trustee under indentures of and generally engage in any kind of
business with, the Borrowers and their affiliates from time to time, all as if
such entity were not the Agent hereunder and without any duty to account
therefor to any Bank.

         9.4. Independent Credit Decisions. Each Bank acknowledges to the Agent
that it has, independently and without reliance upon the Agent or any other
Bank, and based upon such documents and information as it has deemed
appropriate, made its own independent credit analysis and decision to enter into
this Agreement. Each Bank also acknowledges that it will, independently or
through other advisers and representatives but without reliance upon the Agent
or any other Bank, and based upon such documents and information as it shall
deem appropriate at the time, continue to make its own credit decisions in
taking or refraining from taking any action under this Agreement or any Loan
Document.

         9.5. Indemnification. The Banks agree to indemnify the Agent (to the
extent not reimbursed by the Borrowers), ratably in proportion to each Bank's
Commitment Percentage, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses and
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by or asserted against the Agent in such capacity in any way relating to or
arising out of this Agreement or any Loan Document or any action taken or
omitted to be taken by the Agent in such capacity hereunder or under any Loan
Document; provided that none of the Banks shall be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the Agent's gross
negligence or willful misconduct. Without limiting the generality of the
foregoing, each Bank agrees to reimburse the Agent, promptly on demand, for such
Bank's ratable share (based upon the aforesaid apportionment) of any
out-of-pocket expenses (including counsel fees and disbursements) incurred by
the Agent in connection with the preparation, execution, administration or
enforcement of, or the preservation of any rights under, this Agreement and the
Loan Documents to the extent that the Agent is not reimbursed for such expenses
by the Borrowers.

                                       30
<PAGE>

         9.6. Successor Agent. The Agent may resign at any time by giving
written notice of such resignation to the Banks and the Borrowers, such
resignation to be effective only upon the appointment of a successor Agent as
hereinafter provided. Additionally, the Agent may be removed by the Required
Banks if: (i) the aggregate Commitment Percentages of the Agent and its
affiliates do not equal at least fifteen percent (15%); or (ii) a conservator,
receiver or trustee in bankruptcy is appointed for the Agent and such
appointment is not vacated within ninety (90) days of such appointment. Upon any
such resignation or removal of the Agent, the Banks shall jointly appoint a
successor Agent upon written notice to the Borrowers and the retiring or removed
Agent. If no successor Agent shall have been jointly appointed by such Banks and
shall have accepted such appointment within thirty (30) days after a retiring
Agent shall have given notice of resignation, the retiring Agent may, upon
notice to the Borrowers and the Banks, appoint a financial institution as
successor Agent. Upon its acceptance of any appointment as Agent hereunder, the
successor Agent shall succeed to and become vested with all the rights, powers,
privileges and duties of the previous Agent, and the previous Agent shall be
discharged from its duties and obligations as Agent under this Agreement and the
Loan Documents. After any Agent's resignation or removal hereunder, the
provisions hereof shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was the Agent under this Agreement and the Loan
Documents.

         9.7. Allocations Made By Agent. As between the Agent and the Banks,
unless a Bank objecting to a determination or allocation made by the Agent
pursuant to this Agreement delivers to the Agent written notice of such
objection within one hundred twenty (120) days after the date any distribution
was made by the Agent, such determination or allocation shall be conclusive on
such one hundred twentieth day and only those items expressly objected to in
such notice shall be deemed disputed by such Bank. The Agent shall not have any
duty to inquire as to the application by the Banks of any amounts distributed to
them.

         9.8. Benefits of Article IX. The parties hereto agree that the
provisions of this Article IX are intended solely for the benefit of the Agent
and the Banks, and the Borrowers shall not be entitled to rely on any provisions
or assert any such provisions of this Article in any claim or as a defense
against the Agent or the Banks.

         9.9. Reports and Notices. The Borrowers hereby agree that whenever
herein or in any other Loan Document any report notice, statement or other
information is to be given to any Bank or the Agent, such report, notice,
statement or other information shall be given to all Banks contemporaneously and
within the period of time required for giving such report, notice, statement or
information.

X.       SYNDICATION AGENT

         The Syndication Agent shall have no duties or responsibilities (other
than its duties and responsibilities as a Bank) under this Agreement or any of
the other Loan Documents.

XI.      DOCUMENTATION AGENT

         The Documentation Agent shall have no duties or responsibilities (other
than its duties and responsibilities as a Bank) under this Agreement or any of
the other Loan Documents.

                                       31
<PAGE>

XII.     MISCELLANEOUS

         12.1. Waiver. No failure or delay on the part of the Agent or any Bank
or any holder of any Note in exercising any right, power or remedy under any
Loan Document shall operate as a waiver thereof; nor shall any single or partial
exercise of any such right, power or remedy preclude any other or further
exercise thereof or the exercise of any other right, power or remedy under any
Loan Document. The remedies provided under the Loan Documents are cumulative and
not exclusive of any remedies provided by law.

         12.2. Amendments. No amendment, modification, termination or waiver of
any Loan Document or any provision thereof nor any consent to any departure by
any Borrower therefrom shall be effective unless the same shall have been
approved in writing by Required Banks, be in writing and be signed by the Agent
and the applicable Borrower or Borrowers, and then any such waiver or consent
shall be effective only in the instance and for the specific purpose for which
given. No notice to or demand on the Borrowers shall entitle the Borrowers to
any other or further notice or demand in similar or other circumstances.
Notwithstanding any other provision contained in any Loan Document, no
amendment, modification, termination or waiver shall affect the payment of
principal (including without limitation the date when due), reduce any interest
rate margin or any fee provided herein, increase any Revolving Loan Commitment,
extend the Revolver Termination Date, modify the definition of "Required Banks"
or any voting rights of the Banks or amend or modify this Section 12.2 without
the written consent of all of the Banks. The rights and responsibilities of the
Agent hereunder cannot be changed without the Agent's prior written consent.

         12.3. Governing Law. The Loan Documents and all rights and obligations
of the parties thereunder shall be governed by and be construed and enforced in
accordance with the laws of the State of New York without regard to New York or
federal principles of conflict of laws.

         12.4. Participations and Assignments. Each Borrower hereby acknowledges
and agrees that a Bank may at any time:

                  (a) grant participations in all or any portion of its
Revolving Loan Commitment, any Note, or of its right, title and interest therein
or in or to this Agreement (collectively, "Participations") to any other lending
office or to any other bank, lending institution or other entity which has the
requisite sophistication to evaluate the merits and risks of investments in
Participations ("Participants") (but only with the consent of the Agent and
Borrowers, which consent shall not be unreasonably withheld); provided, however,
that: (i) all amounts payable by the Borrowers hereunder shall be determined as
if such Bank had not granted such Participation; (ii) any agreement pursuant to
which any Bank may grant a Participation: (x) shall provide that such Bank shall
retain the sole right and responsibility to enforce the obligations of the
Borrowers hereunder including, without limitation, the right to approve any
amendment, modification or waiver of any provisions of this Agreement; (y) such
participation agreement may provide that such Bank will not agree to any
modification, amendment or waiver of this Agreement without the consent of the
Participant if such modification, amendment or waiver would reduce the principal
of or rate of interest on the Loan or postpone the date fixed for any payment of
principal of or interest on the Loan; and (z) shall not relieve such Bank from
its obligations, which shall remain absolute, to make Loans hereunder; and (iii)
notwithstanding the foregoing, if any Event of Default with respect to Sections
5.16 or 7.1 of this Agreement has occurred within the six (6) months immediately
preceding the date of the proposed participation (whether or not such Event of
Default is ongoing or has been cured), the consent of the Borrowers and the
Agent shall not be necessary to such participation; and

                                       32
<PAGE>

                  (b) assign any of its Loans and its Revolving Credit
Commitment (but only with the consent of the Borrowers and the Agent, which
consent shall not be unreasonably withheld), provided that: (i) each such
assignment shall be in an amount of at least $5,000,000 (unless, after giving
effect to such assignment and all other such assignments by such assigning Bank
occurring simultaneously or substantially simultaneously therewith, such
assigning Bank shall hold no Revolving Credit Commitment or Loan hereunder);
(ii) each such assignment by a Bank of its Loans or Revolving Credit Commitment
shall be made in such manner so that the same portion of its Loans, Note and
Revolving Credit Commitment is assigned to the respective assignee; and (iii)
notwithstanding the foregoing, if any Event of Default with respect to Sections
5.16 or 7.1 of this Agreement has occurred within the six (6) months immediately
preceding the date of the proposed assignment (whether or not such Event of
Default is ongoing or has been cured), the consent of the Borrowers and the
Agent shall not be necessary to such assignment. Upon execution and delivery by
the assignee to the Borrowers and the Agent of an instrument in writing in
substantially the same form as Exhibit 12.4 hereto pursuant to which such
assignee agrees to become a "Bank" hereunder (if not already a Bank) having the
Revolving Credit Commitment(s) and Loans specified in such instrument, and upon
consent thereto by the Borrowers and the Agent, to the extent required above,
the assignee shall have, to the extent of such assignment (unless otherwise
provided in such assignment with the consent of the Borrowers and the Agent),
the obligations, rights and benefits of a Bank hereunder holding the Revolving
Credit Commitment(s) and Loans (or portions thereof) assigned to it (in addition
to the Revolving Credit Commitment(s) and Loans, if any, theretofore held by
such assignee) and the assigning Bank shall, to the extent of such assignment,
be released from the Commitment(s) (or portion(s) thereof) so assigned. Upon
each such assignment the assigning Bank shall pay the Agent an assignment fee of
$3,500.

         12.5. Captions. Captions in the Loan Documents are included for
convenience of reference only and shall not constitute a part of any Loan
Document for any other purpose.

         12.6. Notices. All notices, requests, demands, directions, declarations
and other communications between the Banks and the Borrowers provided for in any
Loan Document shall, except as otherwise expressly provided, be mailed by

telexed, or delivered in hand to the applicable party at the following

         12.7. Sharing of Collections, Proceeds and Set-Offs; Application of
Payments.

                  (a) If any Bank, by exercising any right of set-off,
counterclaim or foreclosure against trade collateral or otherwise, receives
payment of principal or interest or other amount due on any Loan which is
greater than the percentage share of such Bank (determined as set forth below),
the Bank receiving such proportionately greater payment shall purchase such
participations in the Loans held by the other Banks, and such other adjustments
shall be made as may be required, so that all such payments shall be shared by
the Banks on the basis of their percentage shares; provided that if all or any
portion of such proportionately greater payment of such indebtedness is
thereafter recovered from, or must otherwise be restored by, such purchasing
Bank, the purchase shall be rescinded and the purchase price restored to the
extent of such recovery, but without interest being paid by such purchasing
Bank. The percentage share of each Bank shall be based on the portion of the
outstanding Loans of such Bank (prior to receiving any payment for which an
adjustment must be made under this Section in relation to the aggregate
outstanding Loans of all the Banks. Each Borrower agrees, to the fullest extent
it may effectively do so under applicable law, that any holder of a
participation in a Loan or reimbursement obligation, whether or not acquired
pursuant to the foregoing arrangements, may exercise rights of set-off or
counterclaim and other rights with respect to such participation as fully as if
such holder of a participation were a direct creditor of such Borrower in the
amount of such participation. If under any applicable bankruptcy, insolvency or
other similar law, any Bank receives a secured claim in lieu of a set-off to
which this Section would apply, such Bank shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Banks entitled under this Section to share in the benefits of
any recovery on such secured claim.

                  (b) If an Event of Default or Potential Default shall have
occurred and be continuing the Agent and each Bank and the Borrowers agree that
all payments on account of the Loans shall be applied by the Agent and the Banks
as follows:

                           (1) First, to the Agent for any Agent fees then due
                  and payable under this Agreement until such fees are paid in
                  full;

                           (2) Second, to the Agent for any fees, costs or
                  expenses (including expenses described in Section 12.8)
                  incurred by the Agent under any of the Loan Documents or this
                  Agreement, then due and payable and not reimbursed by the
                  Borrowers or the Banks until such fees, costs and expenses are
                  paid in full;

                           (3) Third, to the Banks for their respective shares
                  of all costs, expenses and fees then due and payable from the
                  Borrowers until such costs, expenses and fees are paid in
                  full;

                           (4) Fourth, to the Banks for their percentage shares
                  of the Commitment Fee then due and payable under this
                  Agreement until such fee is paid in full;

                           (5) Fifth, to the Banks for their percentage shares
                  of all interest then due and payable from the Borrowers until
                  such interest is paid in full, which percentage shares shall
                  be calculated by determining each Bank's percentage share
                  (determined as set forth in Section 12.7(a)) of the amounts
                  allocated in (a) above; and

                           (6) Sixth, to the Banks for their percentage shares
                  of the principal amount of the Loans then due and payable from
                  the Borrowers until such principal is paid in full, which
                  percentage shares shall be calculated by determining each
                  Bank's percentage share (determined as set forth in Section
                  12.7(a)) of the amount allocated in (a) above.

         12.8. Expenses of the Agent; Indemnification of the Agent and the
Banks.

                  (a) The Borrowers will from time to time reimburse the Agent
promptly following demand for all reasonable out-of-pocket expenses (including
the reasonable fees and expenses of legal counsel) in connection with (i) the
preparation of the Loan Documents, (ii) the making of any Loans, (iii) the
administration of the Loan Documents and (iv) the enforcement of the Loan
Documents; and will reimburse the Banks for all out-of-pocket expenses
(including reasonable fees and expenses of legal counsel) in connection with the
foregoing, including, without limitation, the enforcement of the Loan Documents,
which expenses shall not be unreasonable. Notwithstanding the foregoing, the
Banks shall use their good faith best efforts to engage common legal counsel
with respect to any attempts by the Banks to enforce any of the Loan Documents.

                  (b) In addition to the payment of the foregoing expenses, the
Borrowers hereby agree, jointly and severally, to indemnify, protect and hold
the Agent, each Bank and any holder of the Notes and the officers, directors,
employees, agents, affiliates and attorneys of the Agent, each Bank and such
holder (collectively, the "Indemnitees") harmless from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses and disbursements of any kind or nature, including reasonable
fees and expenses of legal counsel, which may be imposed on, incurred by, or
asserted against such Indemnitee by any Borrower or other third parties and
arise out of or relate to this Agreement or the other Loan Documents or any
other matter whatsoever related to the transactions contemplated by or referred
to in this Agreement or the other Loan Documents; provided, however, that the
Borrowers shall have no obligation to an Indemnitee hereunder to the extent that
the liability incurred by such Indemnitee has been determined by a court of
competent jurisdiction to be the result of gross negligence or willful
misconduct of such Indemnitee.

         12.9. Survival of Warranties and Certain Agreements. All agreements,
representations and warranties made or deemed made herein shall survive the
execution and delivery of this Agreement, the making of the Loans hereunder and
the execution and delivery of the Notes. Notwithstanding anything in this
Agreement or implied by law to the contrary, the agreements of the Borrowers set
forth in Sections 2.1(f), 2.5, 2.10, and 12.8, and the agreements of the Banks
set forth in Sections 9.1, 9.5 and 12.7 shall survive the payment of the Loans
and the termination of this Agreement. This Agreement shall remain in full force
and effect until the latest to occur of the termination of the Aggregate
Revolving Loan Commitment or the repayment in full of all amounts owed by the
Borrowers under any Loan Document.

         12.10. Severability. The invalidity, illegality or unenforceability in
any jurisdiction of any provision in or obligation under this Agreement, the
Notes or other Loan Documents shall not affect or impair the validity, legality
or enforceability of the remaining provisions or obligations under this
Agreement, the Notes or other Loan Documents or of such provision or obligation
in any other jurisdiction.

         12.11. Banks' Obligations Several; Independent Nature of Banks' Rights.
The obligation of each Bank hereunder is several and not joint and no Bank shall
be the agent of any other (except to the extent the Agent is authorized to act
as such hereunder). No Bank shall be responsible for the obligation or
commitment of any other Bank hereunder. In the event that any Bank at any time
should fail to make a Loan as herein provided, the other Banks, or any of them
as may then be agreed upon, at their sole option, may make the Loan that was to
have been made by the Bank so failing to make such Loan. Nothing contained in
any Loan Document and no action taken by Agent or any Bank pursuant hereto or
thereto shall be deemed to constitute Banks to be a partnership, an association,
a joint venture or any other kind of entity. The amounts payable at any time
hereunder to each Bank shall be a separate and independent debt, and, subject to
the terms of this Agreement, upon giving notice to all other Banks each Bank
shall be entitled to protect and enforce its rights arising out of this
Agreement and it shall not be necessary for any other Bank to be joined as an
additional party in any proceeding for such purpose.

                                       36
<PAGE>

         12.12. No Fiduciary Relationship. No provision in this Agreement or in
any of the other Loan Documents and no course of dealing between the parties
shall be deemed to create any fiduciary duty by Agent or any Bank to the
Borrowers.

         12.13. CONSENT TO JURISDICTION AND SERVICE OF PROCESS. EACH OF THE
BORROWERS, THE AGENT AND EACH BANK HEREBY CONSENTS TO THE JURISDICTION OF ANY
STATE OR FEDERAL COURT LOCATED WITHIN THE SOUTHERN DISTRICT OF NEW YORK AND
IRREVOCABLY AGREES THAT, ANY ACTIONS OR PROCEEDINGS ARISING OUT OF OR RELATING
TO THE NOTES, THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS MAYBE LITIGATED IN SUCH
COURTS. EACH PARTY TO THIS AGREEMENT ACCEPTS FOR ITSELF AND IN CONNECTION WITH
ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF
THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENT, AND
IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION
WITH THIS AGREEMENT, SUCH NOTE, OR SUCH OTHER LOAN DOCUMENT.

         12.14. WAIVER OF JURY TRIAL. EACH OF THE BORROWERS, THE AGENT AND EACH
BANK HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE
OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, ANY OF THE LOAN
DOCUMENTS, OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS
AGREEMENT AND THE LENDER/BORROWER RELATIONSHIP ESTABLISHED HEREBY. THE SCOPE OF
THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY
BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION,
INCLUDING WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY
CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. EACH OF THE BORROWERS,
THE AGENT AND EACH BANK ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL INDUCEMENT
TO THE TRANSACTION, THAT EACH HAS ALREADY RELIED ON THE WAIVER IN ENTERING INTO
THIS AGREEMENT AND THAT EACH WILL CONTINUE TO RELY ON THE WAIVER IN THEIR
RELATED FUTURE DEALINGS. EACH OF THE BORROWERS, THE AGENT AND EACH BANK FURTHER
WARRANTS AND REPRESENTS THAT EACH HAS REVIEWED THIS WAIVER WITH ITS LEGAL
COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS
FOLLOWING CONSULTATION WITH LEGAL COUNSEL. THIS WAIVER IS IRREVOCABLE, AND THE
WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT, THE LOAN DOCUMENTS, OR TO ANY OTHER DOCUMENTS
OR AGREEMENTS RELATING TO THE LOANS. IN THE EVENT OF LITIGATION, THIS AGREEMENT
MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

         12.15. Further Assurances. Each of the parties to this Agreement agrees
that at any time and from time to time upon the written request of any other
party, it will execute and deliver such further documents and do such further
acts and things as such other party may reasonably request in order to effect
the purposes of this Agreement.

         12.16. Counterparts; Effectiveness. This Agreement and any amendment
hereto or waiver hereof may be signed in any number of counterparts, each of
which shall be an original, with the same effect as if the signatures thereto
and hereto were upon the same instrument. This Agreement and any amendments
hereto or waivers hereof shall become effective when the Agent shall have
received signed counterparts or notice by telecopy of the signature page that
the counterpart has been signed and is being delivered to the Agent or facsimile
that such counterparts have been signed by all the parties hereto or thereto.

         12.17. Use of Defined Terms. All words used herein in the singular or
plural shall be deemed to have been used in the plural or singular where the
context or construction so requires. Any defined term used in the singular
preceded by "any" shall be taken to indicate any number of the members of the
relevant class.
