(it being understood that, notwithstanding such exclusion, the proceeds of such
causes of action shall be available for the repayment of the Obligations)) and
on all cash and cash equivalents in the Letter of Credit Account, provided that

are subject on the Filing Date) and (B) any Liens granted after the Filing Date
to provide adequate protection in respect of the Existing Agreements, which

is described in Section 4043 of ERISA and the regulations issued thereunder
(other than a "reportable event" not subject to the provision for 30-day notice
to the PBGC under Section 4043 of ERISA or such regulations) or an event
described in Section 4068 of ERISA excluding events described in Section
4043(c)(9) of ERISA or 29 CFR (S)(S)2615.21 or 2615.23 and excluding events
which would not be reasonably likely (as reasonably determined by the Agent) to
have a material adverse effect on the financial condition, operations, business,
properties or assets of the Borrower and the Guarantors taken as a whole, or
(ii) the withdrawal of the Borrower or any ERISA Affiliate from a Multiple
Employer Plan during a plan year in which it was a "substantial employer", as
such term is defined in Section 4001(c) of ERISA, or the incurrence of liability
by the Borrower or any ERISA Affiliate under Section 4064 of ERISA upon the
termination of a Multiple Employer Plan, or (iii) providing

                                       19
<PAGE>

notice of intent to terminate a Plan pursuant to Section 4041(c) of ERISA or the
treatment of a Plan amendment as a termination under Section 4041 of ERISA, or
(iv) the institution of proceedings to terminate a Plan by the PBGC under
Section 4042 of ERISA, or (v) any other event or condition (other than the
commencement of the Cases and the failure to have made any contribution accrued
as of the Filing Date but not paid) which would reasonably be expected to
constitute grounds under Section 4042 of ERISA for the termination of, or the
appointment of a trustee to administer, any Plan, or the imposition of any
liability under Title IV of ERISA (other than for the payment of premiums to the
PBGC).

          "Total Commitment" shall mean, at any time, the sum of the Commitments
           ----------------
at such time.

          "Transferee" shall have the meaning given such term in Section 2.18.
           ----------

          "Unused Total Commitment" shall mean, at any time, (i) the Total
           -----------------------
Commitment less (ii) the sum of (x) the aggregate outstanding principal amount
of all Loans and (y) the aggregate Letter of Credit Outstandings.

          "Withdrawal Liability" shall have the meaning given such term under
           --------------------
Part I of Subtitle E of Title IV of ERISA.

     SECTION 2.2   Terms Generally. The definitions in Section 1.01 shall apply
                   ---------------
equally to both the singular and plural forms of the terms defined. Whenever the
context may require, any pronoun shall include the corresponding masculine,
feminine and neuter forms. All references herein to Sections, Exhibits and
Schedules shall be deemed references to Sections of, and Exhibits and Schedules
to, this Agreement unless the context shall otherwise require. Except as
otherwise expressly provided herein, all terms of an accounting or financial
nature shall be construed in accordance with GAAP, as in effect from time to
time; provided, however, that for purposes of determining compliance with any
      --------  -------
covenant set forth in Section 6, such terms shall be construed in accordance
with GAAP as in effect on the date of this Agreement applied on a basis
consistent with the application used in the Borrower's audited financial
statements referred to in Section 3.04.

SECTION 3.  AMOUNT AND TERMS OF CREDIT.

     SECTION 3.1   Commitment of the Banks.
                   -----------------------

                                       20
<PAGE>

          (1)  Each Bank severally and not jointly with the other Banks agrees,
upon the terms and subject to the conditions herein set forth (including,
without limitation, the provisions of Section 2.25), to make revolving credit
loans (each a "Loan" and collectively, the "Loans") to the Borrower at any time
               ----                         -----
and from time to time during the period commencing on the date hereof and ending
on the Termination Date (or the earlier date of termination of the Total
Commitment) in an aggregate principal amount not to exceed, when added to such
Bank's Commitment Percentage of the then aggregate Letter of Credit Outstandings
(in excess of the ratable portion of the amount of cash then held in the Letter
of Credit Account pursuant to Section 2.03(b) and allocable to such Bank), the
Commitment of such Bank, which Loans may be repaid and reborrowed in accordance
with the provisions of this Agreement.  At no time shall the sum of the then
outstanding aggregate principal amount of the Loans plus the then aggregate
                                                    ----
Letter of Credit Outstandings exceed the lesser of (i) the Total Commitment of
$100,000,000, as the same may be reduced from time to time pursuant to Section
2.10, and (ii) the Borrowing Base.

          (2)  Each Borrowing shall be made by the Banks pro rata in accordance
                                                         --- ----
with their respective Commitments; provided, however, that the failure of any
                                   --------  -------
Bank to make any Loan shall not in itself relieve the other Banks of their
obligations to lend.

     SECTION 3.2   Borrowing Base.  Notwithstanding any other provision of this
                   --------------
Agreement to the contrary, the aggregate principal amount of all outstanding
Loans plus the then aggregate Letter of Credit Outstandings shall not at any
      ----
time exceed the Borrowing Base and no Loan shall be made or Letter of Credit
issued in violation of the foregoing.

     SECTION 3.3   Letters of Credit.
                   -----------------

          (1)  Upon the terms and subject to the conditions herein set forth,
the Borrower may request a Fronting Bank, at any time and from time to time
after the date hereof and prior to the Termination Date, to issue, and, subject
to the terms and conditions contained herein, such Fronting Bank shall issue,
for the account of the Borrower or a Guarantor one or more Letters of Credit,
provided that no Letter of Credit shall be issued if after giving effect to such
--------
issuance (i) the aggregate Letter of Credit Outstandings shall exceed
$10,000,000 or (ii) the aggregate Letter of Credit Outstandings, when added to
the aggregate outstanding principal amount of the Loans, would exceed the Total
Commitment and, provided further that no Letter of Credit shall be issued if the
                -------- -------
Fronting Bank shall have received notice from the Agent or the Required Banks
that the conditions to such issuance have not been met.

          (2)  No Letter of Credit shall expire later than 60 days after the
Maturity Date, provided that if any Letter of Credit shall be outstanding on the
               --------
Termination Date, the Borrower shall, at or prior to the Termination Date,
except as the Agent may otherwise agree in writing, (i) cause all Letters of
Credit which expire after the Termination Date to be returned to the Fronting
Bank undrawn and marked "canceled" or (ii) if the Borrower is unable to do so in
whole or in part, either (x) provide a "back-to-back" letter of credit to one or
more Fronting Banks in a form satisfactory to such Fronting Bank and the Agent
(in their sole discretion), issued by a bank satisfactory to such Fronting Bank
and the Agent (in their sole discretion), is in an amount equal to

                                       21
<PAGE>

105% of the then undrawn stated amount of all outstanding Letters of Credit
issued by such Fronting Banks and/or (y) deposit cash in the Letter of Credit
Account in an amount equal to 105% of the then undrawn stated amount of all
outstanding Letters of Credit as collateral security for the Borrower's
reimbursement obligations in connection therewith, such cash to be remitted to
the Borrower upon the expiration, cancellation or other termination or
satisfaction of such reimbursement obligations.

          (3)  The Borrower shall pay to each Fronting Bank, in addition to such
other fees and charges as are specifically provided for in Section 2.18 hereof,
such fees and charges in connection with the issuance and processing of the
Letters of Credit issued by such Fronting Bank as are customarily imposed by
such Fronting Bank from time to time in connection with letter of credit
transactions.

          (4)  Drafts drawn under each Letter of Credit shall be reimbursed by
the Borrower in Dollars not later than the first Business Day following the date
such draw is honored and shall bear interest from the date such draw is honored
until the first Business Day following the date such draw is honored at a rate
per annum equal to the Alternate Base Rate plus 3% and thereafter until
                                           ----
reimbursed in full at a rate per annum equal to the Alternate Base Rate plus 5%
                                                                        ----
(computed on the basis of the actual number of days elapsed over a year of 360
days).  The Borrower shall effect such reimbursement (x) if such draw occurs
prior to the Termination Date (or the earlier date of termination of the Total
Commitment), in cash or through a Borrowing initiated by the Agent without the
satisfaction of the conditions precedent set forth in Section 4.02 or (y) if
such draw occurs on or after the Termination Date (or the earlier date of
termination of the Total Commitment), in cash.  Each Bank agrees to make the
Loans described in clause (x) of the preceding sentence notwithstanding a
failure to satisfy the applicable lending conditions thereto or the provisions
of Sections 2.02 or 2.25.  If such draw occurs on or after the Termination Date,
the Borrower shall reimburse the Fronting Bank first from any cash deposit or
cash proceeds of a back-to-back letter of credit in accordance with Section
2.03(b), and then from the Borrower's other assets.

          (5)  Immediately upon the issuance of any Letter of Credit by any
Fronting Bank, such Fronting Bank shall be deemed to have sold to each Bank
other than such Fronting Bank and each such other Bank shall be deemed
unconditionally and irrevocably to have purchased from such Fronting Bank,
without recourse or warranty, an undivided interest and participation, to the
extent of such Bank's Commitment Percentage, in such Letter of Credit, each
drawing thereunder and the obligations of the Borrower and the Guarantors under
this Agreement with respect thereto.  Upon any change in the Commitments
pursuant to Section 10.03, it is hereby agreed that with respect to all Letter
of Credit Outstandings, there shall be an automatic adjustment to the
participations hereby created to reflect the new Commitment Percentages of the
assigning and assignee Banks.  Any action taken or omitted by a Fronting Bank
under or in connection with a Letter of Credit, if taken or omitted in the
absence of gross negligence or willful misconduct, shall not create for such
Fronting Bank any resulting liability to any other Bank.

          (6)  In the event that a Fronting Bank makes any payment under any
Letter of Credit and the Borrower shall not have reimbursed such amount in full
to such Fronting Bank pursuant to this Section, the Fronting Bank shall promptly
notify the Agent, which shall promptly

                                       22
<PAGE>

notify each Bank of such failure, and each Bank shall promptly and
unconditionally pay to the Agent for the account of the Fronting Bank the amount
of such Bank's Commitment Percentage of such unreimbursed payment in Dollars and
in same day funds. If the Fronting Bank so notifies the Agent, and the Agent so
notifies the Banks prior to 11:00 a.m. (New York City time) on any Business Day,
such Banks shall make available to the Fronting Bank such Bank's Commitment
Percentage of the amount of such payment on such Business Day in same day funds.
If and to the extent such Bank shall not have so made its Commitment Percentage
of the amount of such payment available to the Fronting Bank, such Bank agrees
to pay to such Fronting Bank, forthwith on demand such amount, together with
interest thereon, for each day from such date until the date such amount is paid
to the Agent for the account of such Fronting Bank at the Federal Funds
Effective Rate. The failure of any Bank to make available to the Fronting Bank
its Commitment Percentage of any payment under any Letter of Credit shall not
relieve any other Bank of its obligation hereunder to make available to the
Fronting Bank its Commitment Percentage of any payment under any Letter of
Credit on the date required, as specified above, but no Bank shall be
responsible for the failure of any other Bank to make available to such Fronting
Bank such other Bank's Commitment Percentage of any such payment. Whenever a
Fronting Bank receives a payment of a reimbursement obligation as to which it
has received any payments from the Banks pursuant to this paragraph, such
Fronting Bank shall pay to each Bank which has paid its Commitment Percentage
thereof, in Dollars and in same day funds, an amount equal to such Bank's
Commitment Percentage thereof.

     SECTION 3.4   Issuance. Whenever the Borrower desires a Fronting Bank to
                   --------
issue a Letter of Credit, it shall give to such Fronting Bank and the Agent at
least two Business Days' prior written (including telegraphic, telex, facsimile
or cable communication) notice (or such shorter period as may be agreed upon by
the Agent, the Borrower and the Fronting Bank) specifying the date on which the
proposed Letter of Credit is to be issued (which shall be a Business Day), the
stated amount of the Letter of Credit so requested, the expiration date of such
Letter of Credit and the name and address of the beneficiary thereof.

     SECTION 3.5   Nature of Letter of Credit Obligations Absolute. The
                   -----------------------------------------------
obligations of the Borrower to reimburse the Banks for drawings made under any
Letter of Credit shall be unconditional and irrevocable and shall be paid
strictly in accordance with the terms of this Agreement under all circumstances,
including, without limitation (it being understood that any such payment by the
Borrower shall be without prejudice to, and shall not constitute a waiver of,
any rights the Borrower might have or might acquire as a result of the payment
by the Fronting Bank of any draft or the reimbursement by the Borrower thereof):
(i) any lack of validity or enforceability of any Letter of Credit; (ii) the
existence of any claim, setoff, defense or other right which the Borrower or any
Guarantor may have at any time against a beneficiary of any Letter of Credit or
against any of the Banks, whether in connection with this Agreement, the
transactions contemplated herein or any unrelated transaction; (iii) any draft,
demand, certificate or other document presented under any Letter of Credit
proving to be forged, fraudulent, invalid or insufficient in any respect or any
statement therein being untrue or inaccurate in any respect; (iv) payment by a
Fronting Bank of any Letter of Credit against presentation of a demand, draft or
certificate or other document which does not comply with the terms of such
Letter of Credit; (v) any other circumstance or happening

                                       23
<PAGE>

whatsoever, which is similar to any of the foregoing; or (vi) the fact that any
Event of Default shall have occurred and be continuing.

     SECTION 3.6   Making of Loans.
                   ----------------

          (1)  Each Bank may fulfill its Commitment with respect to any Loan by
causing any lending office of such Bank to make such Loan; provided that any
                                                           --------
such use of a lending office shall not affect the obligation of the Borrower to
repay such Loan in accordance with the terms of this Agreement.  Each Bank
shall, subject to its overall policy considerations, use reasonable efforts (but
shall not be obligated) to select a lending office which will not result in the
payment of increased costs by the Borrower pursuant to Section 2.13.

          (2)  The Borrower shall give the Agent prior notice of each Borrowing
hereunder of at least one Business Day (except as provided in the last sentence
of this Section 2.06(b)), such notice shall be irrevocable and shall specify the
amount of the proposed Borrowing (which shall not be less than $1,000,000) and
the date thereof (which shall be a Business Day) and shall contain disbursement
instructions.  Such notice, to be effective, must be received by the Agent not
later than 1:00 p.m., New York City time, on the first Business Day preceding
the date on which such Borrowing is to be made except as provided in the last
sentence of this Section 2.06(b).  The Agent shall promptly notify each Bank of
its proportionate share of such Borrowing and the date of such Borrowing.  On
the borrowing date specified in such notice, each Bank shall make its share of
the Borrowing available at the office of the Agent at 270 Park Avenue, New York,
New York 10017, no later than 12:00 noon, New York City time, in immediately
available funds.  Upon receipt of the funds made available by the Banks to fund
any Borrowing hereunder, the Agent shall disburse such funds in the manner
specified in the notice of borrowing delivered by the Borrower and shall use
reasonable efforts to make the funds so received from the Banks available to the
Borrower no later than 2:00 p.m. New York City time (other than as provided in
the following sentence).  With respect to Loans of $5,000,000 or less, the Banks
shall make such Borrowings available to the Borrower by 4:00 p.m., New York City
time, on the same Business Day that the Borrower gives notice to the Agent of
such Borrowing by 12:00 noon, New York City time, provided that the Agent has
                                                  --------
notified the Banks thereof by 2:00 p.m., New York City time, on such day.

     SECTION 3.7   Repayment of Loans; Evidence of Debt.
                   ------------------------------------

          (1)  The Borrower hereby unconditionally promises to pay to the Agent
for the account of each Bank the then unpaid principal amount of each Loan on
the Termination Date.

          (2)  Each Bank shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Bank
resulting from each Loan made by such Bank, including the amounts of principal
and interest payable and paid to such Bank from time to time hereunder.

          (3)  The Agent shall maintain accounts in which it shall record (i)
the amount of each Loan made hereunder, (ii) the amount of any principal or
interest due and payable or to become

                                       24
<PAGE>

due and payable from the Borrower to each Bank hereunder and (iii) the amount of
any sum received by the Agent hereunder for the account of the Banks and each
Bank's share thereof.

          (4)  The entries made in the accounts maintained pursuant to paragraph
(b) or (c) of this Section shall be prima facie evidence of the existence and
                                    ----- -----
amounts of the obligations recorded therein; provided that the failure of any
                                             --------
Bank or the Agent to maintain such accounts or any error therein shall not in
any manner affect the obligation of the Borrower to repay the Loans in
accordance with the terms of this Agreement.

          (5)  Any Bank may request that Loans made by it be evidenced by a
promissory note.  In such event, the Borrower shall execute and deliver to such
Bank a promissory note payable to the order of such Bank (or, if requested by
such Bank, to such Bank and its registered assigns) in a form furnished by the
Agent and reasonably acceptable to the Borrower.  Thereafter, the Loans
evidenced by such promissory note and interest thereon shall at all times
(including after assignment pursuant to Section 10.03) be represented by one or
more promissory notes in such form payable to the order of the payee named
therein (or, if such promissory note is a registered note, to such payee and its
registered assigns).

     SECTION 3.8   Interest on Loans.
                   -----------------

          (1)  Subject to the provisions of Section 2.09, each Loan shall bear
interest (computed on the basis of the actual number of days elapsed over a year
of 360 days) at a rate per annum equal to the Alternate Base Rate plus 3%.
                                                                  ----

          (2)  Accrued interest on all Loans shall be payable in arrears on the
last calendar day of each month, at maturity (whether by acceleration or
otherwise), after such maturity on demand and upon any repayment or prepayment
thereof (on the amount prepaid).

     SECTION 3.9   Default Interest. If the Borrower or any Guarantor, as the
                   ----------------
case may be, shall default in the payment of the principal of or interest on any
Loan or in the payment of any other amount becoming due hereunder (including,
without limitation, the reimbursement pursuant to Section 2.03(d) of any draft
drawn under a Letter of Credit), whether at stated maturity, by acceleration or
otherwise, the Borrower or such Guarantor, as the case may be, shall on demand
from time to time pay interest, to the extent permitted by law, on such
defaulted amount up to (but not including) the date of actual payment (after as
well as before judgment) at a rate per annum (computed on the basis of the
actual number of days elapsed over a year of 360 days) equal to the Alternate
Base Rate plus 5%.
          ----

     SECTION 3.10  Optional Termination or Reduction of Commitment. Upon at
                   -----------------------------------------------
least two Business Days' prior written notice to the Agent, the Borrower may at
any time in whole permanently terminate, or from time to time in part
permanently reduce, the Unused Total Commitment. Each such reduction of the
Unused Total Commitment shall be in the principal amount of $5,000,000 or any
integral multiple thereof. Simultaneously with each reduction or termination of
the Total Commitment, the Borrower shall pay to the Agent for the account of
each Bank the Commitment Fee accrued on the amount of the Commitment of such
Bank so terminated

                                       25
<PAGE>

or reduced through the date thereof. Any reduction of the Total Commitment
pursuant to this Section shall be applied pro rata to reduce the Commitment of
                                          --- ----
each Bank.

     SECTION 3.11  Mandatory Prepayment; Commitment Termination; Cash
                   --------------------------------------------------
Collateral.
----------

          (1)  If at any time the aggregate principal amount of the outstanding
Loans plus the aggregate Letter of Credit Outstandings exceeds the lesser of (x)
the Total Commitment and (y) the Borrowing Base, the Borrower will within three
Business Days (i) prepay the Loans in an amount necessary to cause the aggregate
principal amount of the outstanding Loans plus the aggregate Letter of Credit
                                          ----
Outstandings to be equal to or less than the Total Commitment and/or the
Borrowing Base, as the case may be, and (ii) if, after giving effect to the
prepayment in full of the Loans, the aggregate Letter of Credit Outstandings in
excess of the amount of cash held in the Letter of Credit Account exceeds the
Total Commitment and/or the Borrowing Base, as the case may be, deposit into the
Letter of Credit Account an amount equal to 105% of the amount by which the
aggregate Letter of Credit Outstandings in excess of the amount of cash held in
the Letter of Credit Account so exceeds the Total Commitment or Borrowing Base,
as the case may be.

          (2)  Upon the sale or other disposition of any of the properties the
completion of which was financed with the proceeds of Loans as permitted by
Section 3.10, the Borrower shall first apply that portion of the Net Proceeds
thereof that is equal to the principal amount of Loans so utilized for such
completion to the prepayment of the Loans.

          (3)  Upon the Termination Date, the Total Commitment shall be
terminated in full and the Borrower shall pay the Loans in full and, except as
the Agent may otherwise agree in writing, if any Letter of Credit remains
outstanding, deposit into the Letter of Credit Account an amount equal to 105%
of the amount by which the sum of the aggregate Letter of Credit Outstandings
exceeds the amount of cash held in the Letter of Credit Account, such cash to be
remitted to the Borrower upon the expiration, cancellation, satisfaction or
other termination of such reimbursement obligations, or otherwise comply with
Section 2.03(b).

     SECTION 3.12  Optional Prepayment of Loans. The Borrower shall have the
                   ----------------------------
right at any time and from time to time to prepay any Loans, in whole or in
part, on the same Business Day if written, telex or facsimile notice is received
by the Agent prior to 1:00 p.m., New York City time, and thereafter upon at
least one Business Day's prior written, telex or facsimile notice to the Agent;
provided, however, that each such partial prepayment shall be in multiples of
--------  -------
$1,000,000. Each notice of prepayment shall specify the prepayment date and the
principal amount of the Loans to be prepaid, shall be irrevocable and shall
commit the Borrower to prepay such Loan in the amount and on the date stated
therein. The Agent shall, promptly after receiving notice from the Borrower
hereunder, notify each Bank of the principal amount of the Loans held by such
Bank which are to be prepaid, the prepayment date and the manner of application
of the prepayment.

     SECTION 3.13  Reserve Requirements; Change in Circumstances.
                   ---------------------------------------------

                                       26
<PAGE>

          (1)  If any Bank shall have determined that the adoption or
effectiveness after the date hereof of any law, rule, regulation or guideline
regarding capital adequacy, or any change in any of the foregoing or in the
interpretation or administration of any of the foregoing by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or any lending office of such
Bank) or any Bank's holding company with any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on such Bank's capital or on the capital of such Bank's holding
company, if any, as a consequence of this Agreement, the Loans made by such Bank
pursuant hereto, such Bank's Commitment hereunder or the issuance of, or
participation in, any Letter of Credit by such Bank to a level below that which
such Bank or such Bank's holding company could have achieved but for such
adoption, change or compliance (taking into account Bank's policies and the
policies of such Bank's holding company with respect to capital adequacy) by an
amount deemed by such Bank to be material, then from time to time the Borrower
shall pay to such Bank such additional amount or amounts as will compensate such
Bank or such Bank's holding company for any such reduction suffered.

          (2)  A certificate of each Bank setting forth such amount or amounts
as shall be necessary to compensate such Bank or its holding company as
specified in paragraph (a) above, shall be delivered to the Borrower and shall
be conclusive absent manifest error. The Borrower shall pay each Bank the amount
shown as due on any such certificate delivered to it within 10 days after its
receipt of the same. Any Bank receiving any such payment shall promptly make a
refund thereof to the Borrower if the law, regulation, guideline or change in
circumstances giving rise to such payment is subsequently deemed or held to be
invalid or inapplicable.

          (3)  Failure on the part of any Bank to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
return on capital with respect to any period shall not constitute a waiver of
such Bank's right to demand compensation with respect to such period or any
other period.  The protection of this Section shall be available to each Bank
regardless of any possible contention of the invalidity or inapplicability of
the law, rule, regulation, guideline or other change or condition which shall
have occurred or been imposed.

     SECTION 3.15  Taxes.
                   -----

          (1)  Any and all payments by the Borrower or any Guarantor hereunder
shall be made free and clear of and without deduction for any and all current or
future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding (i) taxes imposed on or measured by
                                  ---------
the net income or overall gross receipts of the Agent or any Bank (or any
transferee or assignee thereof, including a participation holder (any such
entity being called a "Transferee")) and franchise taxes imposed on the Agent or
                       ----------
any Bank (or Transferee) by the United States or any jurisdiction under the laws
of which the Agent or any such Bank (or Transferee) is organized or in which the
applicable lending office of any such Bank (or Transferee) is located or any
political subdivision thereof or by any other jurisdiction or by any political
subdivision or taxing authority therein other than a jurisdiction in which the
Agent or such Bank (or Transferee) would not be subject to tax but for the
execution and performance of this Agreement and (ii) taxes, levies, imposts,
deductions, charges or withholdings ("Amounts") with respect to payments
                                      -------
hereunder to a Bank (or Transferee) in accordance with laws in effect on the
later of the date of this Agreement and the date such Bank (or Transferee)
becomes a Bank (or Transferee, as the case may be), but not excluding, with
respect to such Bank (or Transferee), any increase in such Amounts solely as a
result of any change in such laws occurring after such later date or any Amounts
that would not have been imposed but for actions (other than actions
contemplated by this Agreement) taken by the Borrower after such later date (all
such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes").  If the Borrower or any
                                              -----
Guarantor shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder to the Banks (or any Transferee) or the Agent, (i) the sum
payable shall be increased by the amount necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section) such Bank (or Transferee) or the Agent (as the case may be)
shall receive an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant taxing authority or
other Governmental Authority in accordance with applicable law.

          (2)  In addition, the Borrower agrees to pay any current or future
stamp or documentary taxes or any other excise or property taxes, charges,
assessments or similar levies that arise from any payment made hereunder or from
the execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Loan Document (hereinafter referred to as "Other Taxes").
                                                                  -----------

          (3)  The Borrower will indemnify each Bank (or Transferee) and the
Agent for the full amount of Taxes and Other Taxes paid by such Bank (or
Transferee) or the Agent, as the case may be, and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted by
the relevant taxing authority or other Governmental Authority.  Such
indemnification shall be made within 30 days after the date any Bank (or
Transferee) or the Agent, as the case may be, makes written demand therefor.  If
a Bank (or Transferee) or the Agent shall become aware that it is entitled to
receive a refund in respect of Taxes or Other Taxes as to which it has been
indemnified by the Borrower pursuant to this Section, it shall promptly notify
the Borrower of the availability of such

                                       28
<PAGE>

refund and shall, within 30 days after receipt of a request by the Borrower,
apply for such refund at the Borrower's expense. If any Bank (or Transferee) or
the Agent receives a refund in respect of any Taxes or Other Taxes as to which
it has been indemnified by the Borrower pursuant to this Section, it shall
promptly notify the Borrower of such refund and shall, within 30 days after
receipt of a request by the Borrower (or promptly upon receipt, if the Borrower
has requested application for such refund pursuant hereto), repay such refund to
the Borrower (to the extent of amounts that have been paid by the Borrower under
this Section with respect to such refund plus interest that is received by the
Bank (or Transferee) or the Agent as part of the refund), net of all out-of-
pocket expenses of such Bank (or Transferee) or the Agent and without additional
interest thereon; provided that the Borrower, upon the request of such Bank (or
                  --------
Transferee) or the Agent, agrees to return such refund (plus penalties, interest
or other charges) to such Bank (or Transferee) or the Agent in the event such
Bank (or Transferee) or the Agent is required to repay such refund. Nothing
contained in this subsection (c) shall require any Bank (or Transferee) or the
Agent to make available any of its tax returns (or any other information
relating to its taxes that it deems to be confidential).

          (4)  Within 30 days after the date of any payment of Taxes or Other
Taxes withheld by the Borrower in respect of any payment to any Bank (or
Transferee) or the Agent, the Borrower will furnish to the Agent, at its address
referred to on the signature pages hereof, the original or a certified copy of a
receipt evidencing payment thereof.

          (5)  Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section shall
survive the payment in full of the principal of and interest on all Loans made
hereunder.

          (6)  Each Bank (or Transferee) that is organized under the laws of a
jurisdiction outside the United States shall, if legally able to do so, prior to
the immediately following due date of any payment by the Borrower hereunder,
deliver to the Borrower such certificates, documents or other evidence, as
required by the Code or Treasury Regulations issued pursuant thereto, including
(A) Internal Revenue Service Form W-8 or W-9 and (B) Internal Revenue Service
Form 1001 or Form 4224 and any other certificate or statement of exemption
required by Treasury Regulation Section 1.1441-1, 1.1441-4 or 1.1441-6(c) or any
subsequent version thereof or successors thereto, properly completed and duly
executed by such Bank (or Transferee) establishing that such payment is (i) not
subject to United States federal withholding tax under the Code because such
payment is effectively connected with the conduct by such Bank (or Transferee)
of a trade or business in the United States or (ii) totally exempt from United
States federal withholding tax or subject to a reduced rate of such tax under a
provision of an applicable tax treaty.  Unless the Borrower and the Agent have
received forms or other documents satisfactory to them indicating that such
payments hereunder or are not subject to United States federal withholding tax
or are subject to such tax at a rate reduced by an applicable tax treaty, the
Borrower or the Agent shall withhold taxes from such payments at the applicable
statutory rate.

          (7)  The Borrower shall not be required to pay any additional amounts
to any Bank (or Transferee) in respect of United States federal withholding tax
pursuant to subsection (a)

                                       29
<PAGE>

above if the obligation to pay such additional amounts would not have arisen but
for a failure by such Bank (or Transferee) to comply with the provisions of
subsection (f) above.

          (8)  Any Bank (or Transferee) claiming any additional amounts payable
pursuant to this Section 2.15 shall use reasonable efforts (consistent with
legal and regulatory restrictions) to file any certificate or document requested
by the Borrower or to change the jurisdiction of its applicable lending office
if the making of such a filing or change would avoid the need for or reduce the
amount of any such additional amounts that may thereafter accrue and would not,
in the sole reasonable determination of such Bank (or Transferee), be otherwise
materially disadvantageous to such Bank (or Transferee).

     SECTION 3.16  Certain Fees. The Borrower shall pay to the Agent, for the
                   ------------

for the period from and including the date of issuance of such Letter of Credit
to and including the date of expiry or draw of such Letter of Credit, computed

Existing Lenders or to the collateral securing such indebtedness. The Banks
agree that so long as no Event of Default or event which with the giving of
notice or lapse of time or both would constitute an Event of Default shall have
occurred, the Borrower and the Guarantors shall be permitted to pay compensation

collateral assignments or similar instruments in recordable form with respect to
such properties on terms reasonably satisfactory to the Agent.

     SECTION 3.21  Right of Set-Off. Subject to the provisions of Section 7.01,
                   ----------------
upon the occurrence and during the continuance of any Event of Default and the

other indebtedness at any time owing by the Agent and each such Bank to or for
the credit or the account of the Borrower or any Guarantor against any and all
of the obligations of such Borrower or Guarantor now or hereafter existing under

demand under any Loan Document and although such obligations may not have been
accelerated.  Each Bank and the Agent agrees promptly to notify the Borrower and
Guarantors after any such set-off and application made by such Bank or by the
Agent, as the case may be, provided that the failure to give such notice shall

not affect the validity of such set-off and application.  The rights of each
Bank and the Agent under this Section are in addition to other rights and
remedies which such Bank and the Agent may have upon the occurrence and during
the continuance of any Event of Default.

<PAGE>

     SECTION 4.2   Due Execution. Upon the entry by the Bankruptcy Court of the
                   -------------
First Day Order (or the Interim Order or the Final Order, when applicable), the
execution, delivery and performance by each of the Borrower and the Guarantors
of each of the Loan Documents to which it is a party (i) are within the
respective corporate powers of each of the Borrower and the Guarantors, have
been duly authorized by all necessary corporate action including the consent of
shareholders where required, and do not (A) contravene the charter or by-laws of
any of the Borrower or the Guarantors, (B) violate any law (including, without
limitation, the Securities Exchange Act of 1934) or regulation (including,
without limitation, Regulations T, U or X of the Board of Governors of the
Federal Reserve System), or any order or decree of any court or governmental
instrumentality, the violation of which could reasonably be expected to have a
Material Adverse Effect, (C) conflict with or result in a breach of, or
constitute a default under, any indenture, mortgage or deed of trust entered

delivered by each of the Borrower and the Guarantors.  This Agreement is, and
each of the other Loan Documents to which the Borrower and each of the
Guarantors is or will be a party, when delivered hereunder or thereunder, will
be, a legal, valid and binding obligation of the Borrower and each Guarantor, as
the case may be, enforceable against the Borrower and the Guarantors, as the
case may be, in accordance with its terms and the Orders.

     SECTION 4.3   Statements Made. The information that has been delivered in

statement delivered pursuant hereto or thereto (other than to the extent that
any such statements constitute projections), taken as a whole and in light of
the circumstances in which made, as of the date so delivered, contained no
untrue statement of a material fact and did not omit to state a material fact
necessary to make such statements not misleading; and, to the extent that any
such information constitutes projections, such projections were prepared in good

periods; such balance sheets and the notes thereto disclose all liabilities,
direct or contingent, of the Borrower and its consolidated Subsidiaries as of

were prepared in

                                       34
<PAGE>

a manner consistent with GAAP, subject (in the case of such fiscal quarter
statement) to normal year end adjustments. No material adverse change in the
operations, business, properties, assets, prospects or condition (financial or
otherwise) of the Borrower and its consolidated Subsidiaries, taken as a whole,
has occurred from that set forth in the Borrower's consolidated financial
statements for the fiscal year ended September 30, 1998 or the fiscal quarter
ended June 30, 1999 other than those which have been disclosed to the Banks in

Bankruptcy Code and the commencement of the Cases (including, without
limitation, those reflected in the financial projections heretofore made
available to the Agent).

reflected on Schedule 3.06 (which Schedules shall be deemed to include any Liens

operations of the Borrower and the Guarantors comply in all material respects
with all applicable environmental, health and safety statutes and regulations,

                                                     -- ---
Borrower's and each of the Guarantor's knowledge, none of the operations of the
Borrower or the Guarantors is the subject of any federal or state investigation

Borrower or any Guarantor is needed to respond to a release of any Hazardous
Waste or Hazardous Substance (as such terms are defined in any applicable state
or federal environmental law or regulations) into the environment; and (iii) to
the Borrower's and each of the Guarantor's knowledge, the Borrower and the

property damage, other casualty, employee fidelity, workers' compensation,

full force and effect and are of a nature and provide such coverage (including
self insurance) as is customarily carried by companies of the size and character
of the Borrower and the Guarantors.

     SECTION 4.9   The Orders. On the date of the making of the initial Loans or
                   ----------
the issuance of the initial Letters of Credit hereunder, whichever first occurs,
the First Day Order will have been entered and will not have been stayed,
amended, vacated, reversed or rescinded (without the prior written consent of
the Agent). On the date of the making of any Loan or the issuance of any Letter
of Credit, the First Day Order, the Interim Order or the Final Order, as the
case may be, shall have been entered and shall not have been amended, stayed,
vacated or rescinded (without the prior written consent of the Agent). Upon the
maturity (whether by the acceleration or otherwise) of any of the Obligations of
the Borrower and the Guarantors hereunder and under the other Loan Documents,

pending or, to the knowledge of the Borrower or the Guarantors, threatened
against or affecting the Borrower or the Guarantors or any of their respective
properties, before any court or governmental department, commission, board,
bureau, agency or instrumentality, domestic or foreign, which if determined
adversely to the Borrower or the Guarantors would have a Material Adverse
Effect.

     SECTION 4.12  Year 2000 Matters. Any reprogramming required to permit the
                   -----------------
proper functioning (but only to the extent that such proper functioning would
otherwise be impaired by the occurrence of the year 2000) in and following the
year 2000 of computer systems and other equipment containing embedded
microchips, in either case owned or operated by the Borrower or any of its
Subsidiaries or used or relied upon in the conduct of their business (including
any such systems and other equipment supplied by others or with which the
computer systems of the Borrower

                                       36

other equipment as so reprogrammed, has been completed in all material respects.
The costs to the Borrower and its Subsidiaries that have not been incurred as of
the date hereof for such reprogramming and testing for the other reasonably
foreseeable consequences to them of any improper functioning of other computer
systems and equipment containing embedded microchips due to the occurrence of
the year 2000 could not reasonably be expected to result in a Default or Event
of Default or to have a Material Adverse Effect. Except for any reprogramming
referred to above, the computer systems of the Borrower and its Subsidiaries are
and, with the ordinary course upgrading and maintenance, will continue for the
term of this Agreement to be, sufficient for the conduct of their business as
currently conducted.

                   -------------------
dated the Closing Date heretofore delivered to the Agent of the Banks:

have a Material Adverse Effect: (i) each of the Borrower and the Guarantors now
has, and has no reason to believe it will not be able to maintain in effect, all
Health Care Permits necessary for the lawful conduct of its business or
operations wherever now conducted and as planned to be conducted, without
limitation, the ownership and operation of its Health Care Facilities pursuant
to all Requirements of Law, (ii) all such Health Care Permits are in full force
and effect and have not been amended or otherwise modified, rescinded, revoked
or assigned, (iii) the Borrower and each of the Guarantors is substantially
complying with the requirements of each such Health Care Permit, and no event
has occurred, and no condition exists, which, with the giving of notice, the
passage of time, or both, would constitute a violation thereof, (iv) neither the
Borrower nor any of the Guarantors has received any written notice of any
violation of any Requirement of Law, (v) to the knowledge of the Borrower, no
condition exists or event has occurred which in itself or with the giving of
notice or the lapse of time, or both, would result in the suspension,
revocation, impairment, forfeiture or non-renewal of any such Health Care
Permit, (vi) there is no claim filed with any Governmental Authority of which
the Borrower or any of the Guarantors has been notified in writing challenging
the validity of any such Health Care Permit and (vii) the continuation, validity
and effectiveness of all such Health Care Permits will not be adversely affected
by the execution and performance of this Agreement or any of the other Loan
Documents.

          (2)  All Health Care Facilities owned, leased, managed or operated by
the Borrower or any of the Guarantors are entitled to participate in, and
receive payment under, the appropriate Medicare, Medicaid and related
reimbursement programs, and any similar state or local government-sponsored
program, to the extent that the Borrower or any of the Guarantors has decided to
participate in any such program, and to receive reimbursement from private and
commercial payers and health maintenance organizations to the extent applicable
thereto. There are no proceedings pending or, to the knowledge of the Borrower,
any proceedings threatened or investigations pending or threatened, by any
Governmental Authority with respect to the Borrower's or any of its
Subsidiaries' participation in the Medicare, Medicaid or related reimbursement
programs and which could reasonably be expected to have a Material Adverse
Effect.

other adjustments to its parameters for including the components of the
Borrowing Base as the Agent shall reasonably require based upon such

bankruptcy, insolvency or other similar law, or otherwise, obtain payment in
respect of its Loans as a result of which the unpaid portion of its Loans is
proportionately less than the unpaid portion of the Loans of any other Bank (a)
it shall promptly purchase at par (and shall be deemed to have thereupon
purchased) from such other Bank a participation in the Loans of such other Bank,
so that the aggregate unpaid principal amount of each Bank's Loans and its
participation in Loans of the other Banks shall be in the same proportion to the
aggregate unpaid principal amount of all Loans then outstanding as the principal
amount of its Loans prior to the obtaining of such payment was to the principal
amount of all Loans outstanding prior to the obtaining of such payment and (b)
such other adjustments shall be made from time to time as shall be equitable to
ensure that the Banks share such payment pro-rata, provided that if any such
non-pro-rata payment is thereafter recovered or otherwise set aside such
purchase of participations shall be rescinded (without interest). The Borrower
expressly consents to the foregoing arrangements and agrees that any Bank
holding (or deemed to

                                       57
<PAGE>

be holding) a participation in a Loan may exercise any and all rights of
banker's lien, setoff (in each case, subject to the same notice requirements as
pertain to clause (iv) of the remedial provisions of Section 7.01) or
counterclaim with respect to any and all moneys owing by the Borrower to such
Bank as fully as if such Bank held a Note and was the original obligee thereon,
in the amount of such participation.

                  ---------------------------

disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or asserted against it or any of them in any way relating to or arising out
of this Agreement or any of the Loan Documents or any action taken or omitted by
it or any of them under this Agreement or any of the Loan Documents to the
extent not reimbursed by the Borrower or the Guarantors (except such as shall

                  ---------------
have the same rights and powers hereunder (including the right to give such
instructions) as the other Banks and may exercise such rights and powers, as
well as its rights and powers under other agreements and instruments to which it
is or may be party, and engage in other transactions with the Borrower or any
Guarantor, as though it were not the Agent of the Banks under this Agreement.

     SECTION 9.8  Independent Banks. Each Bank acknowledges that it has decided
                  -----------------

<PAGE>

          (1)  Each of the Guarantors unconditionally and irrevocably guarantees
the due and punctual payment and performance by the Borrower of the Obligations.
Each of the Guarantors further agrees that the Obligations may be extended or
renewed, in whole or in part, without notice to or further assent from it, and
it will remain bound upon this guaranty notwithstanding any extension or renewal
of any of the Obligations. The Obligations of the Guarantors shall be joint and
several.

          (2)  Each of the Guarantors waives presentation to, demand for payment
from and protest to the Borrower or any other Guarantor, and also waives notice
of protest for nonpayment. The Obligations of the Guarantors hereunder shall not
be affected by (i) the failure of the Agent or a Bank to assert any claim or
demand or to enforce any right or remedy against the Borrower or any other
Guarantor under the provisions of this Agreement or any other Loan Document or
otherwise; (ii) any extension or renewal of any provision hereof or thereof;
(iii) any rescission, waiver, compromise, acceleration, amendment or
modification of any of the terms or provisions of any of the Loan Documents;
(iv) the release, exchange, waiver or foreclosure of any security held by the
Agent for the Obligations or any of them; (v) the failure of the Agent or a Bank
to exercise any right or remedy against any other Guarantor; or (vi) the release
or substitution of any Guarantor or any other Guarantor.

          (3)  Each of the Guarantors further agrees that this guaranty
constitutes a guaranty of performance and of payment when due and not just of
collection, and waives any right to require that any resort be had by the Agent
or a Bank to any security held for payment of the Obligations or to any balance
of any deposit, account or credit on the books of the Agent or a Bank in favor
of the Borrower or any other Guarantor, or to any other Person.

          (4)  Each of the Guarantors hereby waives any defense that it might
have based on a failure to remain informed of the financial condition of the
Borrower and of any other Guarantor and any circumstances affecting the ability
of the Borrower to perform under this Agreement.

          (5)  Each Guarantor's guaranty shall not be affected by the
genuineness, validity, regularity or enforceability of the Obligations or any
other instrument evidencing any Obligations, or by the existence, validity,
enforceability, perfection, or extent of any collateral therefor or by any other
circumstance relating to the Obligations which might otherwise constitute a
defense to this Guaranty. Neither of the Agent, nor any of the Banks makes any
representation or warranty in respect to any such circumstances or shall have
any duty or responsibility whatsoever to any Guarantor in respect of the
management and maintenance of the Obligations.

          (6)  Subject to the provisions of Section 7.01, upon the Obligations
becoming due and payable (by acceleration or otherwise), the Banks shall be
entitled to immediate payment of such Obligations by the Guarantors upon written
demand by the Agent, without further application to or order of the Bankruptcy
Court.

     SECTION 10.2   No Impairment of Guaranty. The obligations of the Guarantors
                    -------------------------
hereundershall not be subject to any reduction, limitation, impairment or
termination for any reason, including, without limitation, any claim of waiver,
release, surrender, alteration or compromise, and shall not be subject to any
defense or set-off, counterclaim, recoupment or termination whatsoever by reason
of the invalidity, illegality or unenforceability of the Obligations. Without
limiting the

                                       60
<PAGE>

generality of the foregoing, the obligations of the Guarantors hereunder
shall not be discharged or impaired or otherwise affected by the failure of the
Agent or a Bank to assert any claim or demand or to enforce any remedy under
this Agreement or any other agreement, by any waiver or modification of any
provision thereof, by any default, failure or delay, willful or otherwise, in
the performance of the Obligations, or by any other act or thing or omission or
delay to do any other act or thing which may or might in any manner or to any
extent vary the risk of the Guarantors or would otherwise operate as a discharge
of the Guarantors as a matter of law, unless and until the Obligations are paid
in full.

     SECTION 10.3   Subrogation. Upon payment by any Guarantor of any sums to
                    -----------
the Agent or a Bank hereunder, all rights of such Guarantor against the Borrower
arising as a result thereof by way of right of subrogation or otherwise, shall
in all respects be subordinate and junior in right of payment to the prior final
and indefeasible payment in full of all the Obligations. If any amount shall be
paid to such Guarantor for the account of the Borrower, such amount shall be
held in trust for the benefit of the Agent and the Banks and shall forthwith be
paid to the Agent and the Banks to be credited and applied to the Obligations,
whether matured or unmatured.

     SECTION 11.3   Successors and Assigns.
                    ----------------------

          (1) This Agreement shall be binding upon and inure to the benefit of
the Borrower, the Agent and the Banks and their respective successors and
assigns.  Neither the Borrower nor any of the Guarantors may assign or transfer
any of their rights or obligations hereunder without the prior written consent
of all of the Banks.  Each Bank may sell participations to any Person in all or
part of any Loan, or all or part of its Commitment, in which event, without
limiting the foregoing, the provisions of Section 2.13 shall inure to the
benefit of each purchaser of a participation (provided that such participant
shall look solely to the seller of such participation for such benefits and the
Borrower's and the Guarantors' liability, if any, under Sections 2.13 and 2.15
shall not be increased as a result of the sale of any such participation) and
the pro rata treatment of payments, as described in Section 2.14, shall be
    --- ----
determined as if such Bank had not sold such participation.  In the event any
Bank shall sell any participation, such Bank shall retain the sole right and
responsibility to enforce the obligations of the Borrower and each of the
Guarantors relating to the Loans, including, without limitation, the right to
approve any amendment, modification or waiver of any provision of this Agreement
(provided that such Bank may grant its participant the right to consent to such
Bank's execution of amendments, modifications or waivers which (i) reduce any
Fees payable hereunder to the Banks, (ii) reduce the amount of any scheduled
principal payment on any Loan or reduce the principal amount of any Loan or the
rate of interest payable hereunder or (iii) extend the maturity of the
Borrower's obligations hereunder).  The sale of any such participation shall not
alter the rights and obligations of the Bank selling such participation
hereunder with respect to the Borrower.

          (2) Each Bank may assign to one or more Banks or Eligible Assignees
all or a portion of its interests, rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitment and the same
portion of the related Loans at the time owing to it), provided, however, that
                                                       --------  -------
(i) other than in the case of an assignment to a Person at least 50% owned by
the assignor Bank, or by a common parent of both, or to another Bank, the Agent
and the Fronting Bank must give their respective prior written consent to such
assignment, which consent will not be unreasonably withheld, (ii) the aggregate
amount of the Commitment and/or Loans of the assigning Bank subject to each such
assignment (determined as of the date the Assignment and Acceptance with respect
to such assignment is delivered to the Agent) shall, unless otherwise agreed to
in writing by the Borrower and the Agent, in no event be less than $1,000,000 or
such lesser amount as is equal to the remaining Commitment and/or Loans of the
assignor thereof and (iii) the parties to each such assignment shall execute and
deliver to the Agent, for its acceptance and recording in the Register (as
defined below), an Assignment and Acceptance with blanks appropriately
completed, together with a processing and recordation fee of $3,500 (for which
the Borrower shall have no liability).  Upon such execution, delivery,
acceptance and recording, from and after the effective date specified in each
Assignment and Acceptance, which effective date shall be within ten Business
Days after the execution thereof (unless otherwise agreed to in writing by the
Agent), (A) the assignee thereunder shall be a party hereto and, to the extent
provided in such Assignment and Acceptance, have the rights and obligations of a
Bank hereunder and (B) the Bank thereunder shall, to the extent provided in such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining
portion of an

                                       62
<PAGE>

assigning Bank's rights and obligations under this Agreement, such Bank shall
cease to be a party hereto).

          (3)  By executing and delivering an Assignment and Acceptance, the
Bank assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows: (i) other than the
representation and warranty that it is the legal and beneficial owner of the
interest being assigned thereby free and clear of any adverse claim, such Bank
assignor makes no representation or warranty and assumes no responsibility with
respect to any statements, warranties or representations made in or in
connection with this Agreement or any of the other Loan Documents or the
execution, legality, validity, enforceability, genuineness, sufficiency or value
of this Agreement or any of the other Loan Documents; (ii) such Bank assignor
makes no representation or warranty and assumes no responsibility with respect
to the financial condition of the Borrower or any Guarantor or the performance
or observance by the Borrower or any Guarantor of any of its obligations under
this Agreement or any of the other Loan Documents or any other instrument or
document furnished pursuant hereto; (iii) such assignee confirms that it has
received a copy of this Agreement and the other Loan Documents, together with
copies of the financial statements referred to in Section 3.04 and such other
documents and information as it has deemed appropriate to make its own credit
analysis and decision to enter into such Assignment and Acceptance; (iv) such
assignee will, independently and without reliance upon the Agent, such Bank
assignor or any other Bank and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (v) such assignee appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Agent by the terms
thereto, together with such powers as are reasonably incidental hereof; and (vi)
such assignee agrees that it will perform in accordance with their terms all
obligations that by the terms of this Agreement are required to be performed by
it as a Bank.

          (4)  The Agent shall maintain at its office a copy of each Assignment
and Acceptance delivered to it and a register for the recordation of the names
and addresses of the Banks and the Commitments of, and principal amount of the
Loans owing to, each Bank from time to time (the "Register").  The entries in
                                                  --------
the Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Guarantors, the Agent and the Banks shall treat each Person the
name of which is recorded in the Register as a Bank hereunder for all purposes
of this Agreement.  The Register shall be available for inspection by the
Borrower or any Bank at any reasonable time and from time to time upon
reasonable prior notice.

          (5)  Upon its receipt of an Assignment and Acceptance executed by an
assigning Bank and the assignee thereunder together with the fee payable in
respect thereto, the Agent shall, if such Assignment and Acceptance has been
completed with blanks appropriately filled and consented to by the Agent and the
Fronting Bank (to the extent such consent is required hereunder), (i) accept
such Assignment and Acceptance, (ii) record the information contained therein in
the Register and (iii) give prompt written notice thereof to the Borrower
(together with a copy thereof). No assignment shall be effective for purposes of
this Agreement unless it has been recorded in the Register as provided in this
paragraph.

          (6)  Any Bank may, in connection with any assignment or participation
or proposed assignment or participation pursuant to this Section 10.03, disclose
to the assignee or

                                       63
<PAGE>

participant or proposed assignee or participant, any information relating to the
Borrower or any of the Guarantors furnished to such Bank by or on behalf of the
Borrower or any of the Guarantors; provided that prior to any such disclosure,
                                   --------
each such assignee or participant or proposed assignee or participant shall
agree in writing to be bound by the provisions of Section 10.04.

          (7) The Borrower hereby agrees, to the extent set forth in the
Commitment Letter, to actively assist and cooperate with the Agent in the
Agent's efforts to sell participations herein (as described in Section 10.03(a))
and assign to one or more Banks or Eligible Assignees a portion of its
interests, rights and obligations under this Agreement (as set forth in Section
10.03(b)).

     SECTION 11.4   Confidentiality.  Each Bank agrees to keep any information
                    ---------------
 delivered or made available by the Borrower or any of the Guarantors to it
confidential from anyone other than persons employed or retained by such Bank
who are or are expected to become engaged in evaluating, approving, structuring
or administering the Loans; provided that nothing herein shall prevent any Bank
                            --------
from disclosing such information (i) to any other Bank, (ii) upon the order of
any court or administrative agency, (iii) upon the request or demand of any
regulatory agency or authority, (iv) which has been publicly disclosed other

Bank, or their respective Affiliates may be a party to the extent reasonably
required, (vi) to the extent reasonably required in connection with the exercise
of any remedy hereunder, (vii) to such Bank's legal counsel and independent
auditors, and (viii) to any actual or proposed participant or assignee of all or

 -----------------
damages and liabilities incurred by such Indemnified Party arising out of claims
made by any Person in any way relating to the transactions contemplated hereby,

     SECTION 11.9   Extension of Maturity.  Should any payment of principal of
                    ---------------------
or interest or any other amount due hereunder become due and payable on a day
other than a Business Day, the maturity thereof shall be extended to the next
succeeding Business Day and, in the case of principal, interest shall be payable
thereon at the rate herein specified during such extension.

     SECTION 11.10  Amendments, etc.
                    ----------------

          (1)  No modification, amendment or waiver of any provision of this
Agreement or the other Loan Documents, and no consent to any departure by the
Borrower or any Guarantor therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Required Banks, and then such waiver
or consent shall be effective only in the specific instance and for  the purpose
for which given; provided, however, that no such modification or amendment shall
                 --------  -------
without the written consent of the Bank affected thereby (x) increase the
Commitment of a Bank (it being understood that a waiver of an Event of Default
shall not constitute an increase in the Commitment of a Bank), or (y) reduce the
principal amount of any Loan or the rate of interest payable thereon, or extend
any date for the payment of interest hereunder or reduce any Fees payable
hereunder or extend the final maturity of the Borrower's obligations hereunder;
and, provided, further, that no such modification or amendment shall without the
     --------  -------
written consent of (A) all of the Banks (i) amend or modify any provision of
this Agreement which provides for the unanimous

                                       65
<PAGE>

consent or approval of the Banks, (ii) amend this Section 10.10 or the
definition of Required Banks or (iii) amend or modify the Super-Priority Claim
status of the Banks contemplated by Section 2.20; or (iv) release all or any
substantial portion of the Liens granted to the Agent hereunder (other than in
connection with dispositions permitted hereunder), under the Orders or under any
other Loan Document, or release any Guarantor; or (B) Banks holding Loans
representing at least 66-2/3% of the aggregate principal amount of the Loans
outstanding, or if no Loans are outstanding, Banks having Commitments
representing at least 66-2/3% of the Total Commitment to (i) amend any of the
advance rates set forth in the definition of the term "Borrowing Base", (ii)
increase the maximum principal amounts of extensions of credit permitted prior
to the entry of the Final Order by Sections 4.01(b)(i) or 4.02(d), (iii)
decrease the percentage of net revenues required to be paid to the Borrower by
MHG in calculating the weekly overhead payment as described in Section 4.02(j)
or otherwise modify, waive or amend the condition precedent set forth therein or
(iv) modify, waive or amend the provisions of Section 6.16.. No such amendment
or modification may adversely affect the rights and obligations of the Agent or
any Fronting Bank hereunder or any Bank in the capacity referred to in Section
6.03(v) without its prior written consent. No notice to or demand on the
Borrower or any Guarantor shall entitle the Borrower or any Guarantor to any
other or further notice or demand in the same, similar or other circumstances.
Each assignee under Section 10.03(b) shall be bound by any amendment,
modification, waiver, or consent authorized as provided herein, and any consent
by a Bank shall bind any Person subsequently acquiring an interest on the Loans
held by such Bank. No amendment to this Agreement shall be effective against the
Borrower or any Guarantor unless signed by the Borrower or such Guarantor, as
the case may be.

          (2)  Notwithstanding anything to the contrary contained in Section
10.10(a), in the event that the Borrower requests that this Agreement be
modified or amended in a manner which would require the unanimous consent of all
of the Banks (or the consent described in clause (B) of the first sentence of
Section 10.10(a)) and such modification or amendment is agreed to by the Super-
majority Banks (as hereinafter defined), then with the consent of the Borrower
and the Super-majority Banks, the Borrower and the Super-majority Banks shall be
permitted to amend the Agreement without the consent of the Bank or Banks which
did not agree to the modification or amendment requested by the Borrower (such
Bank or Banks, collectively the "Minority Banks") to provide for (w) the
                                 --------------
termination of the Commitment of each of the Minority Banks, (x) the addition to
this Agreement of one or more other financial institutions (each of which shall
be an Eligible Assignee), or an increase in the Commitment of one or more of the
Super-majority Banks, so that the Total Commitment after giving effect to such
amendment shall be in the same amount as the Total Commitment immediately before
giving effect to such amendment, (y) if any Loans are outstanding at the time of
such amendment, the making of such additional Loans by such new financial
institutions or Super-majority Bank or Banks, as the case may be, as may be
necessary to repay in full the outstanding Loans of the Minority Banks
immediately before giving effect to such amendment and (z) such other
modifications to this Agreement as may be appropriate.  As used herein, the term
"Super-majority Banks" shall mean, at any time, Banks holding Loans representing
at least 66-2/3% of the aggregate principal amount of the Loans outstanding, or
if no Loans are outstanding, Banks having Commitments representing at least 66-
2/3% of the Total Commitment.

     SECTION 11.11  Severability.  Any provision of this Agreement which is
                    ------------
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such

                                       66
<PAGE>

prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

     SECTION 11.12  Headings.  Section headings used herein are for convenience
                    --------
only and are not to affect the construction of or be taken into consideration in
interpreting this Agreement.

     SECTION 11.13  Execution in Counterparts.  This Agreement may be executed
                    --------------------------
in any number of counterparts, each of which shall constitute an original, but
all of which taken together shall constitute one and the same instrument.

     SECTION 11.14  Prior Agreements.  This Agreement represents the entire
                    ----------------
agreement of the parties with regard to the subject matter hereof and the terms
of any letters and other documentation entered into between the Borrower or a
Guarantor and any Bank or the Agent prior to the execution of this Agreement
which relate to Loans to be made hereunder shall be replaced by the terms of
this Agreement (except as otherwise expressly provided herein with respect to
the Commitment Letter and the fee letter referred to therein, including without
limitation the Borrower's agreement to actively assist the Agent in the
syndication of the transactions contemplated hereby referred to in Section
10.03(g) and including also the provisions of Section 2.16).

     SECTION 11.15  Further Assurances.  Whenever and so often as reasonably
                    ------------------
requested by the Agent, the Borrower and the Guarantors will promptly execute
and deliver or cause to be executed and delivered all such other and further
instruments, documents or assurances, and promptly do or cause to be done all
such other and further things as may be necessary and reasonably required in
order to further and more fully vest in the Agent all rights, interests, powers,
benefits, privileges and advantages conferred or intended to be conferred by
this Agreement and the other Loan Documents.

     SECTION 11.16  WAIVER OF JURY TRIAL.  EACH OF THE BORROWER, THE GUARANTORS,
                    --------------------
THE AGENT AND EACH BANK HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN
ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO ANY OF THE
LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY.
