     notice to the Lenders. Upon satisfaction of the applicable conditions set
     forth in Article IV, the Administrative Agent will make such Loans
     available to the Borrower by 7:00 p.m., New York time by wire transfer of
     such funds, in accordance with instructions reasonably acceptable to the
     Administrative Agent provided by the Borrower.

               (iii) Unless the Administrative Agent shall have been notified in
     writing by any Lender prior to the proposed date of any Borrowing that such
     Lender will not make available to the Administrative Agent such Lender's
     share of such Borrowing, the Administrative Agent may assume that such
     Lender will make such amount available to the Administrative Agent on such
     date in accordance with Section 2.1(b)(ii) of this Agreement and may, in
     reliance upon such assumption, make available to the Borrower a
     corresponding amount. If a Lender has not in fact made its share of the
     applicable Borrowing available to the Administrative Agent, such Lender
     shall forthwith pay to the Administrative Agent on demand such
     corresponding amount with interest thereon, for each day from and including
     the date such amount is made available to the Borrower to but excluding the
     date of payment to the Administrative Agent, at the Federal Funds Rate. If
     such Lender does not pay such amount within three (3) Business Days after
     the date of such Borrowing, the Administrative Agent may make a demand
     therefor from the Borrower, and the Borrower shall, without limitation of
     the Borrower's rights against the defaulting Lender, pay such amount to the
     Administrative Agent, together with interest thereon from the date such
     amount was made available to the Borrower at the interest rate per annum
     applicable to the Loans advanced on the date of such Borrowing. A notice of
     the Administrative Agent submitted to any Lender or the Borrower with
     respect to any amounts owing under this paragraph shall be conclusive in
     the absence of demonstrable error.

               (iv) The failure of any Lender to make any Loan required to be
     made by it shall not relieve any other Lender of its obligations hereunder;
     provided that the Commitments of the Lenders are several and no Lender
     shall be responsible for any other Lender's failure to make any Loan as
     required herein.

     Section 2.2 Interest.

          (a) Each Loan shall bear interest during each Interest Period at a
rate per annum equal to LIBOR for such Interest Period plus the Applicable
Margin.

          (b) Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by the Borrower hereunder is not
paid when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to 1% plus the interest rate otherwise applicable to such Loan
as provided in the above paragraph (a) of this Section. Accrued and unpaid
interest on past due amounts shall be due and payable on demand.


                                       24

<PAGE>

          (c) Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and at such other times as may be specified
herein.

          (d) All interest under this Section 2.2 of this Agreement shall be
computed on the basis of a year of 360 days. The applicable LIBOR shall be
determined by the Administrative Agent, and such determination shall be
conclusive absent demonstrable error.

     Section 2.3 Interest Periods.

          (a) Subject to paragraphs (b), (c), (d) and (e) below, the Borrower
shall select the initial Interest Period for the Loans in the relevant Borrowing
Request.

          (b) The Loans shall at any given time be subject to a single Interest
Period.

          (c) No Interest Period shall extend beyond the Maturity Date.

          (d) If the Borrower fails to select an Interest Period, the Borrower
shall be deemed to have selected an Interest Period of one (1) month.

          (e) Promptly following receipt of a notice from the Borrower selecting
an Interest Period, the Administrative Agent shall advise each Lender of the
details thereof, and if no timely notice is provided by the Borrower, the
Administrative Agent shall notify each Lender of the details of the applicable
Interest Period.

     Section 2.4 Repayment of Loans. The Borrower shall repay to the
Administrative Agent for the account of the Lenders on the Maturity Date the
aggregate principal amount of the Loans outstanding on such date.

     Section 2.5 Use of Proceeds of Loans.

          (a) Use of Proceeds. The proceeds of the Borrowing of Loans shall be
used solely (i) to finance a portion of the Purchase Price (as defined in the
Acquisition Agreement), including transaction financing costs; (ii) to pay fees
payable on the date of the Borrowing to the Lead Arranger and the Administrative
Agent; and (iii) to pay other reasonable costs and expenses incurred by the
Borrower in connection with the closing of the Loans.

          (b) No Monitoring Obligation. The Administrative Agent shall not be
obligated to monitor or verify the use of proceeds of the Loans.

     Section 2.6 Termination or Reduction of Commitments.

          (a) The Borrower may, upon notice to the Administrative Agent,
terminate the Commitments, or from time to time reduce the Commitments; provided
that (i) any such notice shall be received by the Administrative Agent not later
than 11:00 a.m. three (3) Business Days prior to the date of termination or
reduction and (ii) any such partial reduction shall be in an aggregate amount of
$500,000 or any whole multiple of $50,000 in excess thereof. The Administrative
Agent will promptly notify the applicable Lenders of any such notice of


                                       25

<PAGE>

termination or reduction of any of the Commitments. Any reduction of the
Commitments shall be made ratably among the Lenders in accordance with their
respective Commitments. All commitment fees accrued until the effective date of
any termination of the Commitments shall be paid on the effective date of such
termination.

          (b) The Commitments shall automatically terminate on the Commitment
Termination Date.

          (c) Any termination or reduction of any of the Commitments shall be
permanent.

     Section 2.7 Prepayments.

          (a) Terms of All Prepayments. Each prepayment of Loans shall be
accompanied by accrued interest on the amount prepaid, any additional amounts
required pursuant to Section 3.5 of this Agreement and any Hedging Termination
Obligations payable in connection therewith.

          (b) Optional Prepayments.

               (i) The Borrower may at any time or from time to time voluntarily
     prepay Loans in whole or in part without premium or penalty on any Interest
     Payment Date (subject to Section 3.5); provided that the Borrower shall
     deliver notice to the Administrative Agent of any prepayment hereunder,
     which notice must be received by the Administrative Agent not later than
     11:00 a.m. five (5) Business Days prior to any proposed date of prepayment
     of Loans. Any prepayment of Loans pursuant to this Section 2.7(b) shall be
     in a principal amount of $500,000 or a whole multiple of $50,000 in excess
     thereof or, if less, the entire principal amount thereof then outstanding,
     and any prepayment of Loans pursuant to this Section 2.7(b) shall be in an
     amount equal to the HGC Facility Share (but excluding the TGC Revolving
     Loans in the calculation thereof) of an aggregate prepayment being made
     concurrently under this Section 2.7(b) and Section 2.8(b) of the TGC Loan
     Agreement. Each such notice shall be irrevocable and shall specify the date
     and amount of such prepayment.

               (ii) Promptly following receipt of any such notice of voluntary
     prepayment, the Administrative Agent shall advise the applicable Lenders of
     the contents thereof.

          (c) Mandatory Prepayments.

               (i) If during any fiscal year of the Borrower, the aggregate
     cumulative amount of Net Asset Disposition Proceeds for such fiscal year
     exceeds $5,000,000, the Borrower shall, on any date thereafter on which TGC
     is required to make a prepayment of TGC Loans from such Net Asset
     Disposition Proceeds, prepay the Loans in an amount equal to the HGC
     Facility Share of the Net Asset Disposition Proceeds less (A) any portion
     of Net Asset Disposition Proceeds for such fiscal year theretofore applied
     to mandatory prepayment of the Loans and the TGC Loans pursuant to this

     in an aggregate principal amount equal to the HGC Facility Share of the Net
     Debt Proceeds of such incurrence of Indebtedness.

               (iii) If, at any time TGC or any of its Subsidiaries issues or
     sells any Equity Securities, the Borrower shall, immediately after such
     issuance or sale, prepay the outstanding Loans in an aggregate principal
     amount equal to the HGC Facility Share of the Net Equity Proceeds of such
     issuance of such Equity Securities; provided, that no prepayment shall be
     required in respect of any of the following: (i) any capital contribution
     from any Loan Party in the form of Equity Securities or any issuance or
     sale of Equity Securities by any Subsidiary of the Borrower to the Borrower
     or any of the Borrower's Subsidiaries; (ii) the issuance by any Loan Party
     of Equity Securities in connection with the formation of Subsidiaries

               (iv) If at any time TGC or any of its Subsidiaries receive any
     Net Insurance Proceeds or Net Condemnation Proceeds that, together with any
     other Net Insurance Proceeds or Net Condemnation Proceeds received by such
     Persons during the fiscal year of the Borrower in which such date occurs,
     exceeds $10,000,000, the Borrower shall, on any date thereafter on which
     TGC is required to make a prepayment of TGC Loans from such proceeds,
     prepay the Loans in an aggregate amount equal to the HGC Facility Share of
     the Net Insurance Proceeds or Net Condemnation Proceeds, as applicable, in
     such fiscal year (less any amounts used to repair, restore or replace
     Property in accordance with Section 2.8(c)(iv) of the TGC Loan Agreement.

               (v) If at any time any combination of the Backward Interest
     Coverage Ratio or the Projected Interest Coverage Ratio was 3.50:1.00 or
     lower as of the prior three (3) consecutive Calculation Dates, the Borrower
     shall, within ten (10) Business Days after the Borrower or TGC has
     calculated the Backward Interest Coverage Ratio and Projected Interest
     Coverage Ratio as of the most recent such Calculation Date but in any event
     not later than ten days after the date on which the Financial Statements
     for the period then ended are required to be delivered pursuant to Section
     6.1, prepay the Loans in an aggregate amount equal to the HGC Facility
     Share of the aggregate Excess Cash Flow as of the third-preceding
     Calculation Date.

               (vi) If at any time TGC receives proceeds of an indemnification
     payment pursuant to the assignment of the Acquisition Agreement referred to
     in Section 4.1(n), the Borrower shall, on any date thereafter on which TGC
     is required to make a prepayment of TGC Loans from such proceeds, prepay
     the Loans in an aggregate amount


                                       27

<PAGE>

     equal to the HGC Facility Share of such proceeds less the reasonable legal
     expenses and other costs and expenses directly related to such payment paid
     or that are to be paid by TGC (and net of the HGC Facility Share of amounts
     used or reinvested by TGC in accordance with the second sentence of Section

               (vii) If any Change in Control shall occur, the Borrower shall,
     promptly and in any event no later than ten (10) Business Days following
     the occurrence of such event, prepay the outstanding Loans in full.

               (viii) If any Regulatory Event shall occur, the Borrower shall,
     promptly and in any event no later than ten (10) Business Days following

          (a) Commitment Fees. The Borrower agrees to pay to the Administrative
Agent for the account of each Lender a commitment fee equal to 35% of the
Applicable Margin per annum on the daily amount of the Available Commitment of
such Lender during the period from and including the date hereof to but
excluding the Disbursement Date. Accrued commitment fees shall be payable in
arrears on the Disbursement Date. The commitment fees shall be calculated on the
basis of a year of 360 days and for the actual days elapsed (including the first
day but excluding the last day).

          (b) Other Fees. The Borrower agrees to pay to the Lead Arranger and
the Administrative Agent for their own respective accounts fees payable in the
amounts and at the times separately agreed upon between the Borrower and such
parties, which fees shall be deemed to be payable hereunder.

          (c) Fees Fully Earned When Paid. All fees shall be fully earned when
paid and shall not be refundable under any circumstances.

     Section 2.9 Evidence of Indebtedness; Notes. The Loans made by each Lender
shall be evidenced by one or more accounts or records maintained by such Lender
and by the Administrative Agent in the ordinary course of business. The accounts
or records maintained by the Administrative Agent and each Lender shall be
conclusive absent demonstrable error of the amount of the Loans made by the
Lenders to the Borrower and the interest and payments thereon. Any failure to so
record or any error in doing so shall not, however, limit or otherwise affect
the obligation of the Borrower hereunder to pay any amount owing with respect to
the Obligations. In the event of any conflict between the accounts and records
maintained by any Lender and the accounts and records of the Administrative
Agent in respect of such matters, the accounts and records of the Administrative
Agent shall control in the absence of demonstrable error. Upon the request of
any Lender made through the Administrative Agent, the Borrower shall execute and
deliver to such Lender (through the Administrative Agent) a Note, which shall
evidence such Lender's Loans in addition to such accounts or records. Each
Lender may attach schedules to its Note and endorse thereon the date, amount and
maturity of its Loans and payments with respect thereto.


                                       28

     Section 2.10 Payments Generally.

          (a) Each payment by the Borrower hereunder (whether of principal,
interest, fees or any other amount) shall be made prior to 5:00 p.m., New York
time, on the date when due, in Dollars in immediately available funds, without
condition or deduction for any counterclaim, defense, recoupment or setoff. Any
amounts received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to the account of the Administrative Agent (account number 0000000
760000) at Dresdner Bank AG, New York Branch) or such other account as may
hereafter be designated by the Administrative Agent in writing. The
Administrative Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate recipient promptly upon receipt
thereof, in like funds as received.

          (b) If any payment to be made by the Borrower under any Loan Document
becomes due and payable on a day other than a Business Day, the date for payment
shall be extended to the next succeeding Business Day, and such extension of
time shall be reflected in computing interest or fees.

          (c) If at any time insufficient funds are received by and available to
the Administrative Agent to pay fully all amounts of principal, interest and
fees then due hereunder, such funds shall be applied (i) first, towards payment
of interest and fees then due hereunder, ratably among the parties entitled
thereto in accordance with the amounts of interest and fees then due to such
parties, and (ii) second, towards payment of principal then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
principal then due to such parties.

     Section 2.11 Sharing of Payments. If any Lender shall, by exercising any
right of set-off or counterclaim or otherwise, obtain payment in respect of any
principal of or interest on its Loans, resulting in such Lender receiving
payment of a greater proportion of the aggregate amount of such Loans and
accrued interest thereon than the proportion received by any other Lender, then
the Lender receiving such greater proportion shall purchase (for cash at face
value) participations in the Loans of the other Lenders to the extent necessary
so that the benefit of all such payments shall be shared by the Lenders ratably
in accordance with the aggregate amount of principal of and accrued interest on
their respective Loans; provided that (i) if any such participations are
purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price
restored to the extent of such recovery, without interest, and (ii) the
provisions of this paragraph shall not be construed to apply to any payment made
by the Borrower pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans to any assignee or
participant, other than to the Borrower or Affiliate thereof (as to which the
provisions of this paragraph shall apply). The Borrower consents to the
foregoing and agrees, to the extent it may effectively do so under applicable
Legal Requirement, that any Lender acquiring a participation pursuant to the
foregoing arrangements may exercise against the Borrower all its rights of
payment (including


                                       29
<PAGE>

the right of set-off) with respect to such participation as fully as if such
Lender were a direct creditor of the Borrower in the amount of such
participation.

                                   ARTICLE III
                           TAXES AND YIELD PROTECTION

     Section 3.1 Taxes.

          (a) Any and all payments by or on account of any obligation of the
Borrower hereunder or under any other Loan Document shall be made free and clear
of and without deduction for any Indemnified Taxes or Other Taxes; provided that
if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes
from such payments, then (i) the sum payable shall be increased as necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section) the Administrative Agent or Lender
(as the case may be) receives an amount equal to the sum it would have received
had no such deductions been made, (ii) the Borrower shall make such deductions
and (iii) the Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable Legal Requirements.

          (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable Legal
Requirements.

          (c) The Borrower shall indemnify the Administrative Agent and each
Lender, within ten (10) days after written demand therefor, for the full amount
of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such
Lender, as the case may be, on or with respect to any payment by or on account
of any obligation of the Borrower hereunder or under any other Loan Document
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest
and reasonable expenses arising therefrom or with respect thereto, whether or
not such Indemnified Taxes or Other Taxes were correctly or legally imposed or
asserted by the relevant Governmental Authority. A certificate as to the amount
of such payment or liability delivered to the Borrower by a Lender or by the
Administrative Agent on its own behalf or on behalf of a Lender shall be
conclusive absent demonstrable error.

          (d) As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

          (e) Each Foreign Lender shall deliver to the Administrative Agent,
prior to receipt of any payment subject to withholding under the IRC (or upon
accepting an assignment of an interest herein), two duly signed completed copies
of either IRS Form W-8BEN or any successor thereto (relating to such Foreign
Lender and entitling it to an exemption from, or reduction of, withholding tax
on all payments to be made to such Foreign Lender by the Borrower pursuant to
this Agreement) or IRS Form W-8ECI or any successor thereto (relating to


                                       30

<PAGE>

all payments to be made to such Foreign Lender by the Borrower pursuant to this
Agreement) or such other evidence satisfactory to the Borrower and the
Administrative Agent that such Foreign Lender is entitled to an exemption from,
or reduction of, U.S. withholding tax, including any exemption pursuant to
Section 881(c) of the IRC. Thereafter and from time to time, each such Foreign
Lender shall (A) promptly submit to the Administrative Agent such additional
duly completed and signed copies of one of such forms (or such successor forms
as shall be adopted from time to time by the relevant United States taxing
authorities) as may then be available under then current United States laws and
regulations to avoid, or such evidence as is satisfactory to the Borrower and
the Administrative Agent of any available exemption from or reduction of, United
States withholding taxes in respect of all payments to be made to such Foreign
Lender by the Borrower pursuant to this Agreement, and (B) promptly notify the
Administrative Agent of any change in circumstances which would modify or render
invalid any claimed exemption or reduction.

          (f) If any Governmental Authority asserts that the Administrative
Agent did not properly withhold or backup withhold, as the case may be, any tax
or other amount from payments made to or for the account of any Lender, such
Lender shall indemnify the Administrative Agent therefor, including all
penalties and interest, any taxes imposed by any jurisdiction on the amounts
payable to the Administrative Agent under this Section, and costs and expenses
of the Administrative Agent. The obligation of the Lenders under this Section
shall survive the termination of the Commitments, repayment of all other
Obligations hereunder and the resignation of the Administrative Agent.

          (g) If a Lender assigns a Loan to an individual Person that is a
United States resident, such individual shall provide two duly signed and
completed copies of IRS form W-9 (or any successor form thereto) to the
Administrative Agent.

     Section 3.2 Alternate Rate of Interest. If prior to the commencement of any
Interest Period, (a) the Administrative Agent determines (which determination
shall be conclusive absent demonstrable error) that adequate and reasonable
means do not exist for ascertaining LIBOR for such Interest Period or (b) the
Administrative Agent is advised by the Required Lenders that LIBOR determined or
to be determined for such Interest Period will not adequately and fairly reflect
the cost to such Lenders of making or maintaining such Loans for such Interest
Period, the Administrative Agent shall promptly give notice thereof to the
Borrower and such Lenders by telephone or telecopy as promptly as practicable
thereafter and, until the Administrative Agent notifies the Borrower and such
Lenders that the circumstances giving rise to such notice no longer exist, the
Administrative Agent shall promptly give written notice thereof to the Borrower
and such Lenders. If such notice is given, the rate of interest on each
applicable Lender's Loans for each Interest Period thereafter will be the
average cost of funds for the Required Lenders, as reasonably determined by the
Administrative Agent, plus the Applicable Margin.

     Section 3.3 Illegality. If any Lender determines in good faith that any
Legal Requirement has made it unlawful, or that any Governmental Authority has
asserted that it is unlawful, for any Lender or its applicable Lending Office to
make, maintain or fund LIBOR Loans, or to determine or charge interest rates
based upon LIBOR, then, on notice thereof by


                                       31

<PAGE>

such Lender to the Borrower through the Administrative Agent, any obligation of
such Lender to make or continue LIBOR Loans shall be suspended until such Lender
notifies the Administrative Agent and the Borrower that the circumstances giving
rise to such determination no longer exist. Upon receipt of such notice, the
Borrower shall, upon demand from such Lender (with a copy to the Administrative
Agent), prepay, either on the last day of the Interest Period therefor, if such
Lender may lawfully continue to maintain such LIBOR Loans to such day, or
immediately, if such Lender may not lawfully continue to maintain such LIBOR
Loans; provided that if prior to such prepayment date the affected Lender and
the Borrower can agree upon an alternative mutually acceptable basis for
determining the interest rate from time to time applicable to the Loans owing to
such Lender that will avoid such illegality, such interest rate shall take
effect from the date of such agreement and lieu of such required prepayment.
Upon any such prepayment, the Borrower shall also pay accrued interest on the
amount so prepaid.

     Section 3.4 Increased Costs.

          (a) If any Change in Law shall:

               (i) impose, modify or deem applicable any reserve, special
     deposit or similar requirement against assets of, deposits with or for the
     account of, or credit extended by, any Lender (including any reserve
     established by the Federal Reserve Board); or

               (ii) impose on any Lender or the London interbank market any
     other condition affecting this Agreement or Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Loan (or of maintaining its obligation to
make any such Loan) or to reduce the amount of any sum received or receivable by
such Lender hereunder (whether of principal, interest or otherwise), then the
Borrower will pay to such Lender such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.

          (b) If any Lender determines that any Change in Law regarding capital
requirements has or would have the effect of reducing the rate of return on such
Lender's capital or on the capital of such Lender's holding company, if any, as
a consequence of this Agreement or the Loans made by such Lender, to a level
below that which such Lender or such Lender's holding company could have
achieved but for such Change in Law (taking into consideration such Lender's
policies and the policies of such Lender's holding company with respect to
capital adequacy), then from time to time the Borrower will pay to such Lender
such additional amount or amounts as will compensate such Lender or such
Lender's holding company for any such reduction suffered.

          (c) A certificate of a Lender setting forth the amount or amounts
necessary to compensate such Lender or its holding company, as the case may be,
as specified in paragraph (a) or (b) of this Section shall be delivered to the
Borrower and shall be conclusive absent demonstrable error. The Borrower shall
pay such Lender the amount shown as due on any such certificate within ten (10)
days after receipt thereof.


                                       32

<PAGE>

          (d) Failure or delay on the part of any Lender to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender's right to
demand such compensation; provided that the Borrower shall not be required to
compensate a Lender pursuant to this Section for any increased costs or
reductions incurred more than 180 days prior to the date that such Lender
notifies the Borrower of the Change in Law giving rise to such increased costs
or reductions and of such Lender's intention to claim compensation therefor; and
provided, further, that if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the 180-day period referred to above shall be
extended to include the period of retroactive effect thereof.

     Section 3.5 Funding Losses. The Borrower agrees to indemnify each Lender
and to hold each Lender harmless from any loss (excluding losses of anticipated
profit) or expense which such Lender may sustain or incur as a consequence of
(i) any failure by the Borrower (for a reason other than the wrongful failure of
such Lender to make a Loan) to borrow or prepay any Loan on the date or in the
amount notified by the Borrower, or (ii) any payment or prepayment of any Loan
on a day other than the last day of an Interest Period with respect thereto
(whether voluntary, mandatory, by reason of acceleration, or otherwise),
including the amount (if any) determined by the relevant Lender by which (i) the
interest at the LIBOR Rate which such Lender would have received for the period
from the date of receipt of funds to repay or prepay a Loan to the last day of
the applicable Interest Period for such Loan if the principal received had been
paid on the last day of such Interest Period exceeds (ii) the amount which such
Lender would be able to obtain by placing an amount equal to the amount received
by it on deposit with a leading bank in the appropriate interbank market for a
period starting on the Business Day following receipt and ending on the last day
of the applicable Interest Period. Any Lender demanding indemnification for any
loss or expense sustained or incurred by it pursuant to this Section 3.5 shall,
at the time of such demand, deliver to the Borrower a certificate providing a
calculation of and specifying in reasonable detail the additional amount to be
paid to it for any such loss or expense. Each determination by a Lender of the
amounts owing to it pursuant to this Section 3.5 shall be conclusive and binding
in the absence of demonstrable error.

     Section 3.6 Duty to Mitigate; Replacement of Lenders.

          (a) If the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 3.1 of this Agreement, or if any Lender requests compensation under
Section 3.4 of this Agreement, or if the Borrower would be required to prepay
the Loans of any Lender pursuant to Section 3.3 of this Agreement, then such
Lender shall use reasonable efforts to minimize any increased cost or other
compensation payable by the Borrower, including without limitation the
designation of a different lending office for funding or booking its Loans
hereunder or assigning its rights and obligations hereunder to another of its
offices, branches or Affiliates, if, in the judgment of such Lender, such
designation or assignment (i) would eliminate or reduce amounts payable pursuant
to Section 3.1 or 3.4 of this Agreement or avoid the prepayment under Section
3.3 of this Agreement), as the case may be, in the future and (ii) would not
subject such Lender to any unreimbursed cost or expense and would not otherwise
be disadvantageous to such Lender. The Borrower hereby agrees to pay all
reasonable and documented costs and expenses incurred by any Lender in
connection with any such designation or assignment.


                                       33

          (b) If the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 3.1 of this Agreement, or if any Lender requests compensation under
Section 3.4 of this Agreement, or if the Borrower would be required to prepay
the Loans of any Lender pursuant to Section 3.3 of this Agreement, or if any
Lender defaults in its obligation to fund Loans hereunder, then the Borrower
may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 10.4 of this Agreement), all its interests, rights and obligations under
this Agreement to an assignee that shall assume such obligations (which assignee
may be another Lender, if a Lender accepts such assignment); provided that (i)
the Borrower shall have received the prior written consent of the Administrative
Agent, which consent shall not unreasonably be withheld or delayed, (ii) such
Lender shall have received payment of an amount equal to the outstanding
principal of its Loans, accrued interest thereon, accrued fees and all other
amounts payable to it hereunder, from the assignee (to the extent of such
outstanding principal and accrued interest and fees) or the Borrower (in the
case of all other amounts) and (iii) in the case of any such assignment
resulting from payments required to be made pursuant to Section 3.1 of this
Agreement or a claim for compensation under Section 3.4 of this Agreement, such
assignment will result in a reduction in such compensation or payments. A Lender
shall not be required to make any such assignment and delegation if, prior
thereto, as a result of a waiver by such Lender or otherwise, the circumstances
entitling the Borrower to require such assignment and delegation cease to apply.

     Section 3.7 Survival. All of the Borrower's obligations under this Article
III shall survive termination of the Commitments and the payment in full of all
Obligations.

which (i) if adversely determined, could reasonably be expected (alone or in the
aggregate) to have a Material Adverse Effect or (ii) seek to enjoin, either

Effect. Except as set forth on Schedule 5.13, no Loan Party has any liability
with respect to any post-retirement benefit under any Employee Benefit Plan
which is an employee welfare benefit plan (as defined in Section 3(1) of ERISA),
other than liability for health plan continuation coverage described in Part 6
of Title I(B) of ERISA, which liability for post-retirement benefits is

          (b) Each Employee Benefit Plan complies, in both form and operation,
in all material respects, with its terms, ERISA and the IRC, and no condition
exists or event has occurred with respect to any such plan which would result in
the incurrence by any Loan Party or any ERISA Affiliate of any liability, fine
or penalty which would result in a Material Adverse Effect. Each Employee
Benefit Plan, related trust agreement, arrangement and commitment of any Loan
Party is legally valid and binding and in full force and effect. No Employee
Benefit Plan is being audited or investigated by any government agency or is
subject to any pending or threatened material claim or suit other than claims
for benefits in the ordinary course. None of the Loan Parties nor any fiduciary
of any Employee Benefit Plan has, individually or in the aggregate, engaged in a

which would result in a Material Adverse Effect to the Loan Parties, taken as a
whole.

(including secondary liability) to any Multiemployer Plan as a result of a
complete or partial withdrawal from such Multiemployer Plan under Section 4201
of ERISA or as a result of a sale of assets described in Section 4204 of ERISA,
which liability could reasonably be expected to have a Material Adverse Effect.
None of the Loan Parties and the ERISA Affiliates has been notified that any
Multiemployer Plan is in reorganization or insolvent under and within the
meaning of Section 4241 or Section 4245 of ERISA or that any


                                       43

<PAGE>

Multiemployer Plan intends to terminate or has been terminated under Section
4041A of ERISA, except to the extent such event could not reasonably be expected
to have a Material Adverse Effect.

otherwise have the full right to use, under validly existing agreements, all
material patents, licenses, trademarks, trade names, trade secrets, service
marks, copyrights and all rights with respect thereto, which are required to

license or otherwise have the full right to use could not reasonably be expected
to result in a Material Adverse Effect. Each of the patents, trademarks, trade
names, service marks and copyrights owned by any Loan Party which is registered
with any Governmental Authority is set forth on Schedule 5.15. The Loan Parties
conduct their respective businesses without infringement or, to the best of the
Borrower's knowledge, claim of infringement of any trademark, trade name, trade
secret, service mark, patent, copyright, license or other intellectual property
right of other Persons, except where such infringement or claim of infringement
could not reasonably be expected to have a Material Adverse Effect. There is no
infringement or, to the best of the Borrower's knowledge, claim of infringement
by others of any material trademark, trade name, trade secret, service mark,
patent, copyright, license or other intellectual property right of any of the
Loan Parties, except where such infringement or claim of infringement could not
reasonably be expected to have a Material Adverse Effect.

          (a) Each of the Loan Parties has filed or caused to be filed all tax
returns which are required to be filed by it. Each of the Loan Parties has paid,
or made provision for the payment of, all taxes and other Governmental Charges
which have or may have become due pursuant to said returns or otherwise and all
other indebtedness, except such Governmental Charges or indebtedness, if any,
which are being contested in good faith and as to which adequate reserves
(determined in accordance with GAAP) have been established. Proper and accurate
amounts have been withheld by each Loan Party from their employees for all
periods in full and complete compliance with the tax, social security and
unemployment withholding provisions of applicable federal, state, local and
foreign law and such withholdings have been timely paid to the respective
Governmental Authorities. None of the Loan Parties have executed or filed with
the Internal Revenue Service or any other Governmental Authority any agreement
or other document extending, or having the effect of extending, the period for
assessment or collection of any taxes or Governmental Charges.

          (b) No liability for any Tax, directly or indirectly, imposed,

Authority will be incurred by any Loan Party or Lender as a result of the
execution or delivery of this Agreement or any other Loan Documents and no
deduction or withholding in respect of Taxes imposed by or for the account of

business of any of its Subsidiaries, the failure to make such restoration,
repair, replacement or rebuilding will not have a Material Adverse Effect and

(in which event the Net Insurance Proceeds or Net Condemnation Proceeds, as the
case may be, shall be applied to a mandatory prepayment of the Loans in

any insolvency proceeding in relation to, the Borrower or its Subsidiaries, or
for a voluntary arrangement, scheme of arrangement or other analogous step in
relation to the Borrower or its Subsidiaries, or (iv) apply for any order for an
injunction or specific performance in respect of the Borrower or its
Subsidiaries in relation to any of the Loan Documents. Each of the Financing
Parties shall be subject to the terms and provisions of the Intercreditor
Agreement as if it was a signatory thereto.

                                   ARTICLE IX
                                     AGENTS

     Section 9.1 Appointment and Authorization of Agents.

     Each Financing Party hereby irrevocably appoints, designates and authorizes
the Agents to take such action on its behalf under the provisions of this
Agreement and each other Loan Document and to exercise such powers and perform
such duties as are expressly delegated to it by the terms of this Agreement or
any other Loan Document, together with such powers as are reasonably incidental
thereto. Notwithstanding any provision to the contrary contained elsewhere
herein or in any other Loan Document, neither of the Agents shall have any
duties or responsibilities, except those expressly set forth herein or in the
Security Documents, nor shall the Agents have or be deemed to have any fiduciary
relationship with any Financing Party or participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Agents. Without limiting the generality of the foregoing sentence, the use of
the term "agent" herein and in the other Loan Documents with reference to the
Agents is not intended to connote any fiduciary or other implied (or express)
obligations arising under agency doctrine of any applicable Legal Requirement.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

     Section 9.2 Delegation of Duties. Each Agent may execute any of its duties
under this Agreement or any other Loan Document by or through agents, employees
or attorneys-in-fact and shall be entitled to advice of counsel and other
consultants or experts concerning all matters pertaining to such duties. Neither
Agent shall be responsible for the negligence or misconduct of any agent or
attorney-in-fact that it selects in the absence of gross negligence or willful
misconduct.

     Section 9.3 Liability of Agents. None of the Agents, their respective
officers, directors, employees, agents, attorneys-in-fact and Affiliates shall
(a) be liable for any action taken or omitted to be taken by any of them under
or in connection with this Agreement or any other Loan Document or the
transactions contemplated hereby (except for its own gross negligence or willful
misconduct in connection with its duties expressly set forth herein), or (b) be
responsible in any manner to any Financing Party or participant for any recital,
statement, representation or warranty made by any Loan Party or any officer
thereof, contained herein or in any other Loan Document, or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Agents under or in connection with, this Agreement or any other Loan
Document, or the validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document, or for any failure of
any Loan Party or any other party to any Loan Document to perform its
obligations hereunder or thereunder. None of the Agents and any of their
respective officers, directors, employees, agents, attorneys-in-fact and
Affiliates shall be under any obligation to any Financing Party or participant
to ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of any Loan Party or
any Affiliate thereof.


                                       62

     Section 9.4 Reliance by Agents. Each Agent shall be entitled to rely, and
shall be fully protected in relying, upon any writing, communication, signature,
resolution, representation, notice, consent, certificate, affidavit, letter,
telegram, facsimile, telex or telephone message, electronic mail message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to any Loan
Party), independent accountants and other experts selected by such Agent. Each
Agent shall be fully justified in failing or refusing to take any action under
any Loan Document unless it shall first receive such advice or concurrence of
the Required Lenders as it deems appropriate and, if it so request, it shall
first be indemnified to its satisfaction by the Financing Parties against any
and all liability and expense which may be incurred by it by reason of taking or
continuing to take any such action, provided that neither Agent shall be
required to take any action that would expose them it to personal liability or
that is contrary to the Loan Documents or applicable Legal Requirements. The
Agents shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement or any other Loan Document in accordance with a
request or consent of the Required Lenders (or such greater number of Lenders as
may be expressly required hereby in any instance) and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the
Lenders.

     Section 9.5 Notice of Default. The Agents shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest and fees required
to be paid to the Administrative Agent for the account of the Financing Parties,
unless the Administrative Agent shall have received written notice from a
Financing Party or the Borrower referring to this Agreement, describing such
Default and stating that such notice is a "notice of default." The
Administrative Agent will notify the Financing Parties of its receipt of any
such notice. The Administrative Agent shall take such action with respect to
such Default or Event of Default as may be directed by the Required Lenders (or
such other number or percentage of Lenders as shall be necessary under the
circumstances as provided in Section 11.1 of this Agreement; provided, that
unless and until the Administrative Agent has received any such direction, the
Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of the Financing
Parties.

     Section 9.6 Credit Decision; Disclosure of Information. Each Financing
Party acknowledges that neither the Agents nor any of their officers, directors,
employees, agents, attorneys-in-fact or Affiliates has made any representation
or warranty to it, and that no act by the Agents hereafter taken, including any
consent to and acceptance of any assignment or review of the affairs of any Loan
Party or any Affiliate thereof, shall be deemed to constitute any representation
or warranty by the Agents or any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates to any Financing Party as to any matter,
including whether the Agents or any of its officers, directors, employees,
agents, attorneys-in-fact or Affiliates have disclosed material information in
their possession. Each Financing Party represents to the Agents that it has,
independently and without reliance upon the Agents or any of their officers,
directors, employees, agents, attorneys-in-fact or Affiliates and based on such
documents and information as it has deemed appropriate, made its own appraisal
of and investigation into the


                                       63

<PAGE>

business, prospects, operations, property, financial and other condition and
creditworthiness of the Loan Parties and their respective Subsidiaries, and all
applicable bank or other regulatory Laws relating to the transactions
contemplated hereby, and made its own decision to enter into this Agreement and
to extend credit to the Borrower hereunder. Each Financing Party also represents
that it will, independently and without reliance upon the Agents or any of their
officers, directors, employees, agents, attorneys-in-fact or Affiliates and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit analysis, appraisals and decisions in
taking or not taking action under this Agreement and the other Loan Documents,
and to make such investigations as it deems necessary to inform itself as to the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Borrower. Except for notices, reports and other
documents expressly required to be furnished to the Financing Parties by the
Administrative Agent herein, neither Agent shall have any duty or responsibility
to provide any Financing Party with any credit or other information concerning
the business, prospects, operations, property, financial and other condition or
creditworthiness of the Borrower or any of its Affiliates which may come into
the possession of the Agents or any of their officers, directors, employees,
agents, attorneys-in-fact or Affiliates.

     Section 9.7 Indemnification. To the extent that the Borrower fails to pay
any amount required to be paid by it to the Agents or any Indemnitee, each
Lender severally agrees to pay to the Agents or such Indemnitee such Lender's
Pro Rata Share (determined as of the time that the applicable unreimbursed
expense or indemnity payment is sought) of such unpaid amount. The undertaking
in this Section shall survive termination of the Commitments, the payment of all
Obligations and the resignation of either Agent.

     Section 9.8 Agents in their Individual Capacities. The Agents and their
respective Affiliates may make loans to, issue letters of credit for the account
of, accept deposits from, acquire equity interests in and generally engage in
any kind of banking, trust, financial advisory, underwriting or other business
with each of the Loan Parties and their respective Affiliates as though the
Agents were not the Agents hereunder and without notice to or consent of the
Financing Parties. The Financing Parties acknowledge that, pursuant to such
activities, the Agents or their respective Affiliates may receive information
regarding any Loan Party or their respective Affiliates (including information
that may be subject to confidentiality obligations in favor of such Loan Party
or such Affiliate) and acknowledge that the Agents shall be under no obligation
to provide such information to them. With respect to their Loans or other
Outstanding Exposure, the Agents shall have the same rights and powers under
this Agreement as any other Financing Party and may exercise such rights and
powers as though it were not the Administrative Agent or the Collateral Agent,
as the case may be.

     Section 9.9 Successor Administrative Agent. The Administrative Agent may
resign as Administrative Agent upon 30 days' notice to the Lenders. If the
Administrative Agent resigns under this Agreement, the Required Lenders shall
appoint from among the Lenders a successor administrative agent for the Lenders,
which successor administrative agent shall be consented to by the Borrower at
all times other than during the existence of an Event of Default (which consent
of the Borrower shall not be unreasonably withheld or delayed). If no successor
administrative agent is appointed prior to the effective date of the resignation
of the


                                       64

<PAGE>

Administrative Agent, the Administrative Agent may appoint, after consulting
with the Lenders and the Borrower, a successor administrative agent from among
the Lenders. Upon the acceptance of its appointment as successor administrative
agent hereunder, the Person acting as such successor administrative agent shall
succeed to all the rights, powers and duties of the retiring Administrative
Agent and the term "Administrative Agent" shall mean such successor
administrative agent, and the retiring Administrative Agent's appointment,
powers and duties as Administrative Agent shall be terminated. After any
retiring Administrative Agent's resignation hereunder as Administrative Agent,
the provisions of this Article IX and Section 11.3 of this Agreement shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement. If no successor administrative agent
has accepted appointment as Administrative Agent by the date which is 30 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
agent as provided for above.

     Section 9.10 Lead Arranger. The Lead Arranger shall not have any right,
power, obligation, liability, responsibility or duty under this Agreement other
than, to the extent it is a Lender or the Administrative Agent, those applicable
to all Lenders or the Administrative Agent, as the case may be, as such. Each
Lender acknowledges that it has not relied, and will not rely, on the Lead
Arranger in deciding to enter into this Agreement or in taking or not taking
action hereunder.

                                    ARTICLE X
                              HEDGING ARRANGEMENTS

     Section 10.1 Hedging Payments. Each Hedging Bank agrees that it shall not
(i) demand (other than as may be necessary in order to exercise any right to
terminate any Hedging Transaction pursuant to a Lender Hedging Agreement as
permitted under Section 10.2 of this Agreement or required under Section 10.3 of
this Agreement) or receive payment, prepayment or repayment of, or any
distribution in respect of, or on account of, any of the Hedging Obligations in
cash or in kind, or apply any money or property in or towards the discharge of
any Hedging Obligations except for scheduled payments arising under the terms of
the Lender Hedging Agreements, or (ii) permit to exist or receive any security
interest or any financial support (including the giving of any guarantee or the
making of any deposit or payment) for or in respect of any of the Hedging
Obligations other than under the Loan Documents.

     Section 10.2 Voluntary Termination. Each Hedging Bank agrees that it may
terminate a Hedging Transaction pursuant to a Lender Hedging Agreement only upon
the occurrence of any of the following events: (i) the Administrative Agent has
declared that all of the amounts outstanding under the Loan Documents are
immediately due and payable or such acceleration has occurred without notice
from the Administrative Agent pursuant to Section 8.2(a) of this Agreement, (ii)
the Required Lenders have directed the Administrative Agent to seek a lifting of
the automatic stay or any other stay in any Bankruptcy Proceeding so as to
permit an acceleration of all of the amounts outstanding under the Loan
Documents pursuant to Section 8.2(a) of this


                                       65

<PAGE>

Agreement, (iii) early termination is permitted in accordance with the terms of
such Lender Hedging Agreement by the Hedging Bank in the event it becomes
unlawful for such Hedging Bank to perform any absolute or contingent obligation
under such Lender Hedging Agreement, (iv) early termination is permitted in
accordance with the terms of such Lender Hedging Agreement upon the occurrence
of a tax event or tax event upon merger, (v) the Administrative Agent has
requested such termination in accordance with Section 9.3 of this Agreement, or
(vi) an Event of Default occurs under Section 8.1(a) with respect to the Lender
Hedging Agreement entered into by such Hedging Bank.

     Section 10.3 Involuntary Termination or Reduction.

          (a) If the Administrative Agent has declared that all of the amounts
outstanding under the Loan Documents are immediately due and payable or such
acceleration has occurred without notice from the Administrative Agent pursuant
to Section 8.2(a) of this Agreement, each Hedging Bank agrees that, at the
written request of the Administrative Agent (acting at the direction of the
Required Lenders), such Hedging Bank shall exercise its rights to terminate all
hedging transactions under each Lender Hedging Agreement to which it is a party.

          (b) If the aggregate notional amounts hedged under the Lender Hedging
Agreements exceed by more than ten percent (10%) the aggregate principal amount
of the Loans for a period of more than sixty (60) days, the Administrative Agent
(acting at the direction of the Required Lenders) may, by notice to the Hedging
Banks and the Borrower, require that the amounts hedged under the Lender Hedging
Agreements be reduced (allocated ratably among the Lender Hedging Agreements
according to the respective amounts hedged thereunder) to a level equal to no
more than 110% and no less than 100% of the Loans outstanding.

     Section 10.4 Agreement to be Bound by Loan Documents; Benefit of Lien of
Security Documents. By entering the Lender Hedging Agreements, each Hedging Bank
shall be deemed to have agreed to be bound by the provisions set forth in this
Agreement applicable to Hedging Banks and Financing Parties. So long as the
terms thereof are in compliance with this Agreement, each Lender Hedging
Agreement shall be secured by the Liens created by the Security Documents on a
pari passu basis.

                                   ARTICLE XI
                                  MISCELLANEOUS

     Section 11.1 Amendments; Waivers.

          (a) No amendment or waiver of any provision of this Agreement or any
other Loan Document, and no consent to any departure by the Borrower or any
other Loan Party therefrom, shall be effective unless in writing signed by the
Required Lenders and the Borrower or the applicable Loan Party, as the case may
be, and acknowledged by the Administrative Agent; provided that no such
amendment, waiver or consent shall: (i) extend or increase the Commitment of any
Lender without the written consent of such Lender; (ii) postpone any date fixed
by this Agreement or any other Loan Document for any payment or mandatory
prepayment of principal, interest, fees or other amounts due to the Lenders (or
any of them), or postpone the


                                       66

<PAGE>

scheduled date of expiration of any Commitment, without the written consent of
each Lender directly affected thereby; (iii) reduce the principal of, or the
rate of interest specified herein on, any Loan, or any fees or other amounts
payable hereunder or under any other Loan Document, or change the manner of
calculation of the amount of any mandatory prepayment that would result in a
reduction of any such prepayment, without the written consent of each Lender
directly affected thereby; (iv) change Section 2.12 of this Agreement in a
manner that would alter the pro rata sharing of payments required thereby
without the written consent of each Lender; (v) change any provision of this
Section or the definition of "Required Lenders" or any other provision hereof
specifying the number or percentage of Lenders required to waive, amend or
modify any rights hereunder or make any determination or grant any consent
hereunder, without the written consent of each Lender; or (vi) release all or
any material part of the Collateral without the written consent of each Lender
and Hedging Bank (except that (A) any release in connection with a sale or other
disposition of Collateral authorized by Section 7.3 of this Agreement shall not
require the approval of any Lender or Hedging Bank) and (B) any amendment,
waiver or consent which modifies the terms of Section 7.3 of this Agreement
(including any modification relating to the prepayment of proceeds from any such
sale or other disposition) shall require the consent of the Required Lenders);
and provided, further, that (A) no amendment, waiver or consent shall, without
the written consent of the Administrative Agent in addition to the Lenders
required above, affect the rights or duties of the Administrative Agent under
this Agreement or any other Loan Document, (B) no amendment, waiver or consent
shall, without the written consent of each Hedging Bank directly affected
thereby in addition to the Lenders required above, affect the rights or duties
of such Hedging Bank under this Agreement or any other Loan Document, and (C)
any separate fee agreement between the Borrower and the Administrative Agent in
its capacity as such or between the Borrower and the Lead Arranger in their
capacities as such may be amended or modified by such parties; and provided,
further, that any waiver of conditions precedent set forth in Section 4.1(f) of
this Agreement which relate to the perfection of a security interest in
Collateral can be waived by the Administrative Agent in its discretion, provided
that such condition shall instead be satisfied after the Effective Date and
within time periods established by the Administrative Agent in its discretion.

          (b) No failure or delay by the Administrative Agent, or any Lender in
exercising any right or power hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Administrative Agent and the
Lenders hereunder are cumulative and are not exclusive of any rights or remedies
that they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by the Borrower therefrom shall in any event be
effective unless the same shall be permitted by paragraph (a) of this Section,
and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given. Without limiting the generality of the
foregoing, the making of a Loan shall not be construed as a waiver of any
Default, regardless of whether the Administrative Agent or any Lender may have
had notice or knowledge of such Default at the time.

facsimile document or signature.

          (c) Electronic mail and internet and intranet websites may be used

     Section 11.3 Expenses; Indemnity; Damage Waiver.

          (a) The Borrower shall pay (i) all reasonable and documented
out-of-pocket expenses incurred by the Administrative Agent and its Affiliates,
including the reasonable and documented fees, charges and disbursements of
counsel for the Administrative Agent, in connection with the preparation,
negotiation and execution of this Agreement and the other Loan Documents and any
amendment, modification or waiver of the provisions hereof or thereof (whether
or not the transactions contemplated hereby or thereby shall be consummated),
the syndication of the credit facilities provided for herein, and administration
of the transactions contemplated hereby and thereby, and (ii) all reasonable and
documented out-of-pocket expenses incurred by the Administrative Agent or any
Lender, including the fees, charges and disbursements of any counsel for the
Administrative Agent or any Lender, in connection with the enforcement,
attempted enforcement or protection of its rights in connection with this
Agreement or any other Loan Document, including its rights under this Section,
or in connection with the Loans made hereunder, including all such reasonable
out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of the Obligations.

          (b) The Borrower shall indemnify the Administrative Agent, each Lender
and each of the officers, directors, employees, agents, attorneys-in-fact and
Affiliates of any of the foregoing Persons (each such Person being called an
"Indemnitee") against, and hold each Indemnitee harmless from, any and all
losses, claims, damages, liabilities and related expenses, including the
reasonable and documented fees, charges and disbursements of any counsel for any
Indemnitee, incurred by or asserted against any Indemnitee arising out of, in
connection with, or as a result of (i) the execution or delivery of any Loan
Document or any agreement or instrument contemplated thereby, the performance by
the parties hereto of their respective obligations hereunder or the consummation
of the transactions contemplated thereby, the consummation of the Acquisition
and the consummation of the TGC Financing, (ii) any Commitment or Loan or the
use of the proceeds therefrom, (iii) any actual or alleged presence or release

                                       69

<PAGE>

Materials on or from any property owned or operated by any Loan Party, or
liability under any Environmental Laws related in any way to any Loan Party, or
(iv) any actual or prospective claim, litigation, investigation or proceeding
relating to any of the foregoing, whether based on contract, tort or any other
theory; provided, that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses are determined by a court of competent jurisdiction by final
and nonappealable judgment to have resulted from the gross negligence, bad faith
or willful misconduct of such Indemnitee.

          (c) In the event that any claim or demand by a third party for which
the Borrower may be required to indemnify an Indemnitee hereunder (a "Claim") is
asserted against or sought to be collected from any Indemnitee by a third party,
such Indemnitee shall as promptly as practicable notify the Borrower in writing
of such Claim, and such notice shall specify (to the extent known) in reasonable
detail the amount of such Claim and any relevant facts and circumstances
relating thereto; provided, however, that any failure to give such prompt notice
or to provide any such facts and circumstances shall not constitute a waiver of
any rights of the Indemnitee, except to the extent that the rights of the
Borrower are actually prejudiced thereby.

          (d) The Borrower shall be entitled to appoint counsel of its choice at
the expense of the Borrower to represent an Indemnitee in any action for which
indemnification is sought (in which case the Borrower shall not thereafter be
responsible for the fees and expenses of any separate counsel retained by that
Indemnitee except as set forth below); provided, however, that such counsel
shall be satisfactory to such Indemnitee. Notwithstanding the Borrower's
election to appoint counsel to represent an Indemnitee in any action, such
Indemnitee shall have the right to employ separate counsel (including local
counsel, but only one such counsel in any jurisdiction in connection with any
action), and the Borrower shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the Borrower to
represent the Indemnitee would present such counsel with a conflict of interest;
(ii) the actual or potential defendants in, or targets of, any such action
include both the Indemnitee and the Borrower and the Indemnitee shall have
reasonably concluded that there may be legal defenses available to it and/or
other Indemnitees which are different from or additional to those available to
the Borrower; (iii) the Borrower shall not have employed counsel to represent
the Indemnitee within a reasonable time after notice of the institution of such
action; or (iv) the Borrower shall authorize the Indemnitee to employ separate
counsel at the Borrower's expense. The Borrower shall not be liable for any
settlement or compromise of any action or claim by an Indemnitee affected
without your prior written consent, which consent shall not be unreasonably
withheld.

          (e) To the extent permitted by applicable law, the Borrower shall not
assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed
to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement, any other Loan Document, or any agreement or instrument
contemplated hereby or arising out of the activities in connection herewith or
therewith.

          (f) All amounts due under this Section shall be payable not later than

          (g) The agreements in this Section shall survive the termination of
the Commitments and repayment of all other Obligations.

     Section 11.4 Successors and Assigns.

          (a) The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto (excluding the Borrower) upon the execution
and delivery hereof by MGH and Dresdner Bank AG London Branch, as Administrative
Agent and Lender and their respective successors and assigns permitted hereby,
and upon the execution and delivery hereof by the Borrower, shall be binding
upon and inure to the benefit of all of the parties hereto, except that (i)
neither MGH nor the Borrower may assign or otherwise transfer any of its rights
or obligations hereunder without the prior written consent of each Lender (and
any attempted assignment or transfer by the Borrower without such consent shall
be null and void) and (ii) no Lender may assign or otherwise transfer its rights
or obligations hereunder except in accordance with this Section. Nothing in this
Agreement, expressed or implied, shall be construed to confer upon any Person
(other than the parties hereto, their respective successors and assigns
permitted hereby, Participants (to the extent provided in paragraph (c) of this
Section) and, to the extent expressly contemplated hereby, the Related Parties
of each of the Administrative Agent and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

          (b) (i) Any Lender may assign to one or more other Lenders, Affiliates
of any Lender or Eligible Assignees approved by the Administrative Agent and (so
long as no Event of Default is continuing) the Borrower (which approvals shall
not be unreasonably withheld or delayed) all or a portion of its rights and
obligations under this Agreement (including all or a portion of its Commitment
and the Loans at the time owing to it); provided that (A) no approval of the
Administrative Agent or the Borrower shall be required for any assignment to an
assignee that is a Lender or an Affiliate of a Lender immediately prior to
giving effect to such assignment, (B) except in the case of an assignment to a
Lender or an Affiliate of a Lender or an assignment of the entire remaining
amount of the assigning Lender's Loans and Commitment, the amount of the Loans
and Commitment of the assigning Lender subject to each such assignment
(determined as of the date the Assignment and Assumption with respect to such
assignment is delivered to the Administrative Agent) shall not be less than
$5,000,000 unless each of the Administrative Agent and, so long as no Event of
Default has occurred and is continuing, the Borrower otherwise consents; (C)
each partial assignment shall be made as an assignment of a proportionate part
of all the assigning Lender's rights and obligations under this Agreement; (D)
the parties to each assignment shall execute and deliver to the Administrative
Agent an Assignment and Assumption, together with a processing and recordation
fee of $3,500 and any required tax forms; and (E) the assignee, if it shall not
be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire.

               (ii) Subject to acceptance and recording thereof pursuant to
     paragraph (b)(iv) of this Section, from and after the effective date
     specified in each Assignment and Assumption the assignee thereunder shall
     be a party hereto and, to the


                                       71
<PAGE>

     extent of the interest assigned by such Assignment and Assumption, have the
     rights and obligations of a Lender under this Agreement, and the assigning
     Lender thereunder shall, to the extent of the interest assigned by such
     Assignment and Assumption, be released from its obligations under this
     Agreement (and, in the case of an Assignment and Assumption covering all of
     the assigning Lender's rights and obligations under this Agreement, such
     Lender shall cease to be a party hereto but shall continue to be entitled
     to the benefits of Sections 3.1, 3.3, 3.4 and 11.3 of this Agreement). Upon
     request, the Borrower (at its expense) shall execute and deliver a Note to
     the assignee Lender. Any assignment or transfer by a Lender of rights or
     obligations under this Agreement that does not comply with this Section
     11.4 shall be treated for purposes of this Agreement as a sale by such
     Lender of a participation in such rights and obligations in accordance with
     paragraph (c) of this Section.

               (iii) The Administrative Agent, acting solely for this purpose as
     an agent of the Borrower, shall maintain at one of its offices a copy of
     each Assignment and Assumption delivered to it and a register for the
     recordation of the names and addresses of the Lenders, and the Commitment
     of, and principal amount of the Loans owing to, each Lender pursuant to the
     terms hereof from time to time (the "Register"). The entries in the
     Register shall be conclusive, and the Borrower, the Administrative Agent
     and the Lenders may treat each Person whose name is recorded in the
     Register pursuant to the terms hereof as a Lender hereunder for all
     purposes of this Agreement, notwithstanding notice to the contrary. The
     Register shall be available for inspection by the Borrower and any Lender,
     at any reasonable time and from time to time upon reasonable prior notice.

               (iv) Upon its receipt of a duly completed Assignment and
     Assumption and required tax forms executed by an assigning Lender and an
     Eligible Assignee, the assignee's completed Administrative Questionnaire
     (unless the assignee shall already be a Lender hereunder) and the
     processing and recordation fee referred to in paragraph (b)(i) of this
     Section, the Administrative Agent shall accept such Assignment and
     Assumption and record the information contained therein in the Register. No
     assignment shall be effective for purposes of this Agreement unless it has
     been recorded in the Register as provided in this paragraph.

          (c) (i) Any Lender may, without the consent of or notice to the
Borrower or the Administrative Agent, sell participations to one or more banks
or other entities (each, a "Participant") in all or a portion of such Lender's
rights and obligations under this Agreement (including all or a portion of its
Commitment and the Loans owing to it); provided that (A) such Lender's
obligations under this Agreement shall remain unchanged, (B) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (C) the Borrower, the Administrative Agent and the other
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement. Any
agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement or instrument may provide that
such Lender will not, without the consent of


                                       72

<PAGE>

the Participant, agree to any amendment, modification or waiver described in the
first proviso to Section 11.1(a) of this Agreement that affects such
Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees
that each Participant shall be entitled to the benefits of Sections 3.1, 3.3 and
3.4 of this Agreement to the same extent as if it were a Lender and had acquired
its interest by assignment pursuant to paragraph (b) of this Section.

               (ii) A Participant shall not be entitled to receive any greater
     payment under Section 3.1, 3.4 or 3.5 of this Agreement than the applicable
     Lender would have been entitled to receive with respect to the
     participation sold to such Participant. Without limitation of the preceding
     sentence, (i) a Participant that would be a Foreign Lender if it were a
     Lender shall not be entitled to the benefits of Section 3.1 of this
     Agreement unless the Borrower is notified of the participation sold to such
     Participant and such Participant agrees, for the benefit of the Borrower,
     to comply with Section 3.1(e) of this Agreement as though it were a Lender
     and (ii) a Participant that is a United States resident individual shall
     not be entitled to the benefits of Section 3.1 as if it were a Lender
     unless the Participant agrees to comply with Section 3.1(g) of this
     Agreement as though it were a Lender.

          (d) Any Lender may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement to secure obligations of
such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this Section shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or assignment of
a security interest shall release a Lender from any of its obligations hereunder
or substitute any such pledgee or assignee for such Lender as a party hereto.

     Section 11.5 Confidentiality. Each of the Administrative Agent and the
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential), (b) to the extent requested
by any Governmental Authority, (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (d) to any other party
to this Agreement or any other Loan Document, (e) in connection with the
exercise of any remedies hereunder or under any other Loan Document or any suit,
action or proceeding relating to this Agreement or any other Loan Document or
the enforcement of rights hereunder or thereunder, (f) subject to an agreement
containing provisions substantially the same as those of this Section, to (i)
any assignee of or Participant in, or any prospective assignee of or Participant
in, any of its rights or obligations under this Agreement or their respective
advisers, or (ii) any actual or prospective counterparty (or their respective
advisors) to any swap or derivative transaction relating to the Borrower and its
obligations, (g) with the consent of the Borrower or (h) to the extent such
Information becomes publicly available other than as a result of a breach of
this Section. For the purposes of this Section, "Information" means all
information received from the Borrower relating to any Loan Party or its
business, other than any such information that is available to the
Administrative Agent or any Lender on a non-confidential basis from a source
other than the Borrower that is not prohibited from transmitting the information
to the Administrative Agent or such Lender by a


                                       73

<PAGE>

contractual or legal obligation. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered
to have complied with its obligation to do so if such Person has exercised the
same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

     Section 11.6 Limitation on Interest. Notwithstanding anything to the
contrary contained in any Loan Document, the interest and fees paid or agreed to
be paid under the Loan Documents shall not exceed the maximum rate of
non-usurious interest permitted by applicable Legal Requirement (the "Maximum
Rate"). If the Administrative Agent or any Lender shall receive interest or a
fee in an amount that exceeds the Maximum Rate, the excessive interest or fee
shall be applied to the principal of the outstanding Obligations or, if it
exceeds the unpaid principal, refunded to Borrower. In determining whether the
interest or a fee contracted for, charged, or received by the Administrative
Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent
permitted by applicable Legal Requirement, (a) characterize any payment that is
not principal as an expense, fee, or premium rather than interest, (b) exclude
voluntary prepayments and the effects thereof, and (c) amortize, prorate,
allocate, and spread in equal or unequal parts the total amount of interest
throughout the contemplated term of the Obligations.

     Section 11.7 Right of Setoff. If an Event of Default shall have occurred
and be continuing, each Lender and each of its Affiliates is hereby authorized
at any time and from time to time, to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other obligations at any time owing
by such Lender or Affiliate to or for the credit or the account of the Borrower
against any of and all the obligations of the Borrower now or hereafter existing
under this Agreement held by such Lender, irrespective of whether or not such
Lender shall have made any demand under this Agreement and although such
obligations may be unmatured; provided that if any such set off is effected
prior to acceleration of the Loans pursuant to Section 8.2 of this Agreement and
all Events of Default are cured prior to any such acceleration, such set off
shall be rescinded and the deposits and other amounts so set off shall be
restored to the Borrower, without interest. The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

     Section 11.8 Nonliability of Lenders. The Borrower acknowledges and agrees
that:

          (a) Any inspections of any property of the Borrower made by or through
the Administrative Agent or Lenders are for purposes of administration of the
Loan Documents only, and the Borrower is not entitled to rely upon the same
(whether or not such inspections are at the expense of Borrower);

          (b) The relationship between the Borrower and the Administrative Agent
and Lenders is, and shall at all times remain, solely that of borrowers and
lenders; neither the Administrative Agent nor any Lender shall under any
circumstance be construed to be partners or joint venturers of any Loan Party or
its Affiliates; neither the Administrative Agent nor any Lender shall under any
circumstance be deemed to be in a relationship of confidence or trust or a
fiduciary relationship with any Loan Party or its Affiliates, or to owe any
fiduciary duty to any


                                       74

<PAGE>

Loan Party or its Affiliates; neither the Administrative Agent nor the Lenders
undertake or assume any responsibility or duty to any Loan Party or its
Affiliates to select, review, inspect, supervise, pass judgment upon or inform
any such Person of any matter in connection with the operations of such Person;
each Loan Party and its Affiliates shall rely entirely upon their own judgment
with respect to such matters; and any review, inspection, supervision, exercise
of judgment or supply of information undertaken or assumed by the Administrative
Agent or any Lender in connection with such matters is solely for the protection
of the Administrative Agent and each Lenders and neither any Loan Party nor any
other Person is entitled to rely thereon; and

     Section 11.9 Integration. This Agreement, together with the other Loan
Documents, comprises the complete and integrated agreement of the parties on the
subject matter hereof and thereof and supersedes all prior agreements, written
or oral, on such subject matter. In the event of any conflict between the
provisions of this Agreement and those of any other Loan Document, the
provisions of this Agreement shall control; provided that the inclusion of
supplemental rights or remedies in favor of the Administrative Agent or the
Lenders in any other Loan Document shall not be deemed a conflict with this
Agreement. Each Loan Document was drafted with the joint participation of the
respective parties thereto and shall be construed neither against nor in favor
of any party, but rather in accordance with the fair meaning thereof.

     Section 11.10 Governing Law. This Agreement shall be governed by and
construed in accordance with the law of the State of New York.

     Section 11.11 Submission To Jurisdiction; WAIVER OF JURY TRIAL.

          (a) The Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court
of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court
from any thereof, solely for purposes of any action or proceeding arising out of
or relating to this Agreement (and not as a general submission to New York law),
or for recognition or enforcement of any judgment, and each of the parties
hereto hereby irrevocably and unconditionally agrees that all claims in respect
of any such action or proceeding may be heard and determined in such New York
State or, to the extent permitted by law, in such federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement shall
affect any right that the Administrative Agent, or any Lender may otherwise have
to bring any action or proceeding relating to this Agreement against the
Borrower or its properties in the courts of any jurisdiction.

          (b) The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement in any court referred to in
paragraph (a) of this Section. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.


                                       75

<PAGE>

          (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 11.2 of this Agreement.
Nothing in this Agreement will affect the right of any party to this Agreement
to serve process in any other manner permitted by law.

          (d) EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT IT
MAY HAVE TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUR OF OR RELATING TO
ANY LOAN DOCUMENT OR THE TRANSACTION CONTEMPLATED HEREBY OR THEREBY (WHETHER
FOUNDED IN CONTRACT OR TORT OR OTHERWISE). EACH PARTY HERETO ACKNOWLEDGES THAT
IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT
BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS PARAGRAPH.

     Section 11.12 Severability. If any provision of this Agreement or the other
Loan Documents is held to be illegal, invalid or unenforceable, (a) the
legality, validity and enforceability of the remaining provisions of this
Agreement and the other Loan Documents shall not be affected or impaired thereby
and (b) the parties shall endeavor in good faith negotiations to replace the
illegal, invalid or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     Section 11.13 Headings. The table of contents and the headings of Articles,
Sections, Exhibits and Schedules have been included herein for convenience of
reference only, are not part of this Agreement, and shall not be taken into
consideration in interpreting this Agreement.

     Section 11.14 Counterparts. This Agreement may be executed by one or more

same instrument. A set of the copies of this Agreement signed by all the parties
shall be maintained by the Borrower and the Administrative Agent.

     Section 12.2 Certain Rights and Obligations. Until the Borrower shall
become a party to this Agreement or the Commitments are terminated:

          (a) MGH shall be bound by the provisions of this Agreement and perform
the obligations of the Borrower under this Agreement as if it were the Borrower
(excluding all provisions of, or obligations arising under, in Articles V, VI
and VII of this Agreement); provided, however, that MGH also agrees to perform
the obligations of the Borrower set forth in Section 6.2 of this Agreement to
the extent that MGH shall be able to do so by virtue of any rights that it may
have under the Acquisition Agreement or by virtue of the Borrower providing any
information or notice of the type referred to therein. Until the Borrower shall
become a party to this Agreement or the Commitments are terminated, MGH may
exercise any of the rights of the Borrower hereunder;

          (b) no amendment or waiver of this Agreement pursuant to Section 11.1
of this Agreement shall require the consent of the Borrower;

          (c) the Borrower shall have no rights or obligations under this

or warranties under this Agreement and shall not be subject to any of the
covenants set forth herein.

     Section 12.3 Covenants of MGH. Until the earlier of the Effective Date or
the date on which Commitments are terminated, MGH covenants and agrees that:

          (a) MGH shall not agree to waive or amend any material provision of

          (c) MGH shall not disclose to any Person any of the terms of this

by the Loan Parties of the Loan Documents or as a result of any filing required
by any Governmental Authority; and

          (d) MGH shall use commercially reasonable efforts to seek to obtain

                                       77

thereof and developments in connection therewith. In the event that it becomes
apparent that a modification to any provision of this Agreement or the other
Loan Documents contemplated by this Agreement relating to the Collateral
contemplated to secure the Obligations will be required in order to obtain any
such Governmental Authorization, the Lenders and MGH agree to negotiate in good
faith to effectuate such modification.

     This Control Agreement, dated as of [________], 200[__] (this "Agreement"),
among HGC HOLDINGS, LLC (the "Borrower"), [COLLATERAL AGENT], as Collateral
Agent (the "Collateral Agent") for the benefit of the Secured Parties (as
defined in the Loan Agreement referred to below), and [BANK], in its capacity as
a "bank" as defined in Section 9-102 of Article 9 of the UCC (in such capacity,
the "Operating Account Bank"). Capitalized terms used but not defined herein
shall have the meanings assigned thereto in the Loan Agreement dated as of
November [__], 2005 (as amended, restated, supplemented or otherwise modified
from time to time, the "Loan Agreement") among the Borrower, the Lenders party
thereto, and Dresdner Bank AG London Branch, as Administrative Agent (the
"Administrative Agent"). All references herein to the "UCC" means the Uniform
Commercial Code as in effect from time to time in the State of [____________].

     WHEREAS, pursuant to that certain Security Agreement, dated as of November
[__], 2005, between the Borrower and the Collateral Agent (the "Security
Agreement"), the Borrower has granted a security interest in substantially all
of its assets.

     NOW THEREFORE, the parties hereto hereby agree, for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, as
follows:

     Section 1. Maintenance of Account. The Operating Account Bank hereby
confirms and agrees that it has established and shall maintain in the name of
the Borrower account number [_________] (the "Account"), and the Operating
Account Bank shall not change the name or account number of the Account without
the prior written consent of the Collateral Agent.

     Section 2. Control of the Account. If at any time the Operating Account
Bank shall receive any instructions originated by the Collateral Agent directing
the disposition of funds in the Account, the Operating Account Bank shall comply
with such instructions without further consent by the Borrower or any other
person. The Operating Account Bank hereby acknowledges that it has received
notice of the security interest of the Collateral Agent in the Account and
hereby acknowledges and consents to such lien.

     Section 3. Subordination of Lien; Waiver of Set-Off. In the event that the
Operating Account Bank has or subsequently obtains by agreement, by operation of
law or otherwise a security interest in the Account or any funds credited
thereto, the Operating Account Bank hereby agrees that such security interest
shall be subordinate to the security interest of the Collateral Agent. Money and
other items credited to the Account will not be subject to deduction, set-off,
banker's lien, or any other right in favor of any person other than the


                                    Exh. D-1

<PAGE>

Collateral Agent (except that the Operating Account Bank may set off (i) all
amounts due to the Operating Account Bank in respect of customary fees and
expenses for the routine maintenance and operation of the Account and (ii) the
face amount of any checks which have been credited to the Account but are
subsequently returned unpaid because of uncollected or insufficient funds).

     Section 4. Choice of Law. This Agreement shall be governed by the laws of
the State of [_________]. Regardless of any provision in any other agreement,
for purposes of the UCC and Article 9 of the UCC as adopted in the State of
[________] shall be deemed to be the Operating Account Bank's jurisdiction
(within the meaning of Section 9-304 of Article 9 of the UCC).

     Section 5. Conflict with Other Agreements.

     (a) In the event of any conflict between this Agreement (or any portion
thereof) and any other agreement now existing or hereafter entered into, the
terms of this Agreement shall prevail;

     (b) No amendment or modification of this Agreement or waiver of any right
hereunder shall be binding on any party hereto unless it is in writing and is
signed by all of the parties hereto; and

     (c) The Operating Account Bank hereby confirms and agrees that it has not
entered into, and until the termination of this Agreement, will not enter into,
any agreement with any other person relating to the Account and/or any funds
credited thereto pursuant to which it has agreed to comply with instructions
originated by such persons as contemplated by Section 9-104 of Article 9 of the
UCC.

     Section 6. Adverse Claims. The Operating Account Bank does not know of any
liens, claims or encumbrances relating to the Account. If any person asserts any
lien, encumbrance or adverse claim (including any writ, garnishment, judgment,
warrant of attachment, execution or similar process) against the Account, the
Operating Account Bank will promptly notify the Collateral Agent and the
Borrower thereof.

     Section 7. Maintenance of Account. In addition to, and not in lieu of the
obligation of the Operating Account Bank to honor instructions as set forth in
Section 2 hereof, the Operating Account Bank agrees to maintain the Account as
follows:

     (a) Statements and Confirmations. The Operating Account Bank will promptly
send copies of all statements, confirmations and other correspondence concerning
the Account simultaneously to each of the Borrower and the Administrative Agent
at their addresses set forth in Section 9.

     (b) Tax Reporting. All interest, if any, relating to the Account, shall be
reported to the Internal Revenue Service and all state and local taxing
authorities under the name and taxpayer identification number of the Borrower.

     (c) Withdrawal of Funds. If the Operating Account Bank (x) receives a
withdrawal request from the Borrower and (y) has not theretofore received a
notice from the


                                    Exh. D-2

<PAGE>

Collateral Agent (pursuant to Section 2 or otherwise) prohibiting withdrawals,
then the Operating Account Bank shall not be liable to the Collateral Agent for
funding the Borrower's withdrawal, it being acknowledged and agreed that the
Collateral Agent shall look solely to the Borrower in this regard.

     Section 8. Indemnification of Operating Account Bank. The Borrower hereby
agrees that (i) the Operating Account Bank is released from any and all
liabilities to the Borrower arising from the terms of this Agreement and the
compliance of the Operating Account Bank with the terms hereof, except to the
extent that such liabilities arise from the Operating Account Bank's negligence,
and (ii) the Borrower, its successors and assigns shall at all times indemnify
the Operating Account Bank from and against any and all claims, actions and
suits of others arising out of the terms of this Agreement or the compliance of
the Operating Account Bank with the terms hereof, except to the extent that such
arises from the Operating Account Bank's negligence.

     Section 9. Successors; Assignment. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns, except that the Borrower may not assign or transfer any of its rights
or obligations under this Agreement the prior written consent of the Collateral
Agent.

     Section 10. Notices. Any notice, request or other communication required or
permitted to be given under this Agreement shall be in writing and deemed to
have been properly given when delivered in person, or when sent by telecopy and
electronic confirmation of error-free receipt is received or two (2) days after

                                 Lien Priorities

     2.1 Lien Priority.

          (a) Priority. Notwithstanding (i) the date, time, method, manner or
     order of grant, attachment or perfection (or failure to perfect) of any
     Liens granted to the Subordinated Financing Parties on all or any portion
     of the Common Collateral or of any Liens granted to the Senior Financing
     Parties on all or any portion of the Common Collateral, and regardless of
     how such Lien was acquired (whether by grant, statute, operation of law,
     subrogation or otherwise), (ii) the order or time of filing or recordation
     of any document or instrument for perfecting the Liens in favor of the
     Senior Agent or the Subordinated Agent (or any Senior Financing Party or
     Subordinated Financing Party) in any Common Collateral, (iii) any provision
     of the UCC, the Bankruptcy Code or any applicable law, the Senior Documents

     Subordinated Agent, in each case, either directly or through agents, holds
     possession of, or has control over, all or any part of the Common
     Collateral, (v) the fact that any Liens in favor of the Senior Financing
     Parties securing any of the Senior Obligations are (A) to the extent
     permitted under the Senior


                                    Exh. F-11

<PAGE>

     Loan Agreement, subordinated to any Lien securing any obligation of the
     Senior Borrower other than the Senior Obligations or (B) otherwise
     subordinated, voided, avoided, invalidated, or lapsed, or (vi) any other
     circumstance whatsoever, in each case, other than in connection with the
     occurrence of an Improper Act, the Subordinated Financing Parties hereby
     agree that: (x) any Lien on any Common Collateral securing the Senior
     Obligations now or hereafter held by the Senior Financing Parties shall be
     senior in priority to all Liens on any Common Collateral securing the
     Subordinated Obligations; and (y) any Lien on any Common Collateral now or
     hereafter held by the Subordinated Financing Parties shall be junior and
     subordinate in priority to any and all Liens on any Common Collateral
     securing the Senior Obligations.

          (b) Effect of Perfection or Failure to Perfect. Notwithstanding any
     failure by the Senior Financing Parties or the Subordinated Financing
     Parties to perfect its security interests in any Common Collateral or any
     avoidance, invalidation or subordination by any third party or court of the
     security interests in any Common Collateral granted to any such Person
     (except for any such avoidance, invalidation or subordination due to an
     Improper Act), the priority and rights as between the Senior Financing
     Parties on the one hand and the Subordinated Financing Parties on the other
     hand with respect to any Common Collateral shall be as set forth in this
     Agreement.

          (c) Nature of Senior Obligations. The Subordinated Financing Parties
     acknowledge that a portion of the Senior Obligations are revolving in
     nature and that the amount thereof that may be outstanding at any time or
     from time to time may be increased or reduced and subsequently reborrowed,
     and that the terms of the Senior Obligations may be modified, extended or
     amended from time to time, and the aggregate amount of the Senior
     Obligations may be increased, replaced or refinanced, in each event, in
     compliance with the terms of this Agreement, without notice to or consent
     by the Subordinated Financing Parties and without affecting the provisions
     hereof. Except as otherwise expressly provided in this Agreement, the Lien
     priorities provided in this Section shall not be altered or otherwise
     affected by any such amendment, modification, supplement, extension,
     repayment, reborrowing, increase, replacement, renewal, restatement or
     refinancing of either the Senior Obligations or the Subordinated
     Obligations, or any portion thereof.

     2.2 Prohibition on Contesting Liens. The Subordinated Financing Parties and
the Senior Financing Parties each agree that it shall not (and hereby waives any
right to) contest or object to or support any other Person in contesting or
objecting to, in any proceeding (including any Bankruptcy Proceeding), the
priority, perfection, validity or enforceability of any Lien in any Common
Collateral granted to the other, or the provisions of this Agreement.

                        Enforcement, Standstill, Waivers

     3.1 Standstill and Waivers. Until the date upon which the Discharge of
Senior Obligations shall have occurred, whether or not any Bankruptcy Proceeding
has been

<PAGE>

commenced by or against either Borrower or any of their respective subsidiaries,
the Subordinated Financing Parties (except to the extent permitted under Section
3.2(c) and Article VI):

          (i) shall not (i) accelerate the maturity of the Subordinated
     Obligations, (ii) take any action or institute any proceedings to collect
     or enforce the payment of any of the Subordinated Obligations, (iii) take
     any action under the Subordinated Collateral Documents or otherwise to
     foreclose or sell or otherwise realize upon any Subordinated Collateral or
     otherwise available to it under applicable law, (iv) commence, prosecute or
     participate in any administrative, legal or equitable action against either
     Borrower relating to any Subordinated Obligation, or (v) commence or join
     in the commencement of a proceeding under any bankruptcy, insolvency,
     liquidation, reorganization or other similar law in respect of any of
     either Borrower in its capacity as a holder of Subordinated Obligations;

          (ii) shall not (i) oppose, object to or contest in any manner, any
     foreclosure, sale, lease, exchange, transfer or other disposition of any
     Senior Collateral by the Senior Financing Parties, or any other exercise of
     any rights or remedies by or on behalf of the Senior Financing Parties in
     respect of the Senior Documents, including the commencement or prosecution
     of any enforcement action under applicable law or the Senior Documents, or
     (ii) object to the forbearance by the Senior Financing Parties from
     bringing or pursuing any foreclosure proceeding or action or any other
     exercise of any rights or remedies under the Senior Documents;

          (iii) shall not institute any suit or other proceeding or assert in
     any suit, Bankruptcy Proceeding or other proceeding any claim against the
     Senior Financing Parties seeking damages from or other relief by way of
     specific performance, instructions or otherwise, with respect to, and none
     of the Senior Financing Parties shall be liable for, any action taken or
     omitted to be taken by the Senior Financing Parties with respect to any
     Common Collateral or pursuant to the Senior Documents; provided, that this
     provision shall not prevent the Subordinated Financing Parties from
     asserting claims against the Senior Agent for damages arising from its bad
     faith, gross negligence or willful misconduct in performing its duties and
     obligations hereunder; or

          (iv) shall not take, receive or accept any Common Collateral or any
     proceeds from enforcement against any Common Collateral, except in
     accordance with the provisions of this Agreement.

     3.2 Exclusive Enforcement; Nature of Rights.

          (a) Limitation on Action by Subordinated Financing Parties. Until the
     date upon which the Discharge of Senior Obligations shall have occurred,
     whether or not any Bankruptcy Proceeding has been commenced by or against
     either Borrower or any of their respective subsidiaries, the Subordinated
     Financing Parties agree that the Senior Financing Parties shall have the
     exclusive right to enforce rights, exercise remedies (including setoff) and
     make determinations under the Senior Documents, including


                                    Exh. F-13

<PAGE>

     regarding release, disposition or restrictions with respect to the Common
     Collateral, without any consultation with or the consent of the
     Subordinated Financing Parties. In exercising rights and remedies under the
     Senior Documents, the Senior Financing Parties may enforce the provisions
     thereof and exercise remedies thereunder in such order and in such manner
     as they may determine in the exercise of their sole discretion. Such
     exercise and enforcement shall include the rights of an agent appointed by
     them to sell or otherwise dispose of Common Collateral upon foreclosure, to
     incur expenses in connection with such sale or disposition, and to exercise
     all the rights and remedies of a secured party under the UCC of any
     applicable jurisdiction and of a secured creditor under bankruptcy or
     similar laws of any applicable jurisdiction.

          (b) Limitation on Foreclosure Upon HGC Investment Subsidiary Pledge
     and K-1 Pledge. Until the date upon which the Discharge of Senior
     Obligations shall have occurred, the Subordinated Financing Parties shall
     not shall foreclose upon or transfer any of the Pledged Collateral (as such
     term is defined in the HGC Investment Subsidiary Pledge Agreement or the
     K-1 Pledge Agreement) if such action would result in a Change in Control
     under the Senior Loan Agreement.

          (c) Permitted Action by Subordinated Financing Parties.
     Notwithstanding anything to the contrary contained herein, nothing in this
     Agreement shall be construed to limit or impair in any way the right of the
     Subordinated Financing Parties (i) to accelerate the maturity of the
     Subordinated Obligations if the Senior Financing Parties shall have
     accelerated the maturity of the Senior Obligations, (ii) to commence or
     participate in any action of the type described in clause (i), (ii) or
     (iii) of subsection 3.1(a) taken by any Senior Financing Party, (iii) to
     join in the commencement of a proceeding of the type described in clause
     (iv) of subsection 3.1(a) if any Senior Financing Party has commenced or
     joined in the commencement of such a proceeding, (iv) to accrue interest at
     the default rates under the Subordinated Loan Agreement as provided
     therein, or (v) to bid for, or purchase, Common Collateral at any private
     or judicial foreclosure or sale upon such Common Collateral initiated by
     the Senior Financing Parties.

     3.3 No Additional Rights For the Borrowers Hereunder. If any Senior
Financing Party or Subordinated Financing Party enforces its rights or remedies
in violation of the terms of this Agreement, the Borrowers shall not be entitled
to use such violation as a defense to any action by the Senior Financing Parties
or the Subordinated Financing Parties, nor to assert such violation as a
counterclaim or basis for set off or recoupment against the Senior Financing
Parties or the Subordinated Financing Parties.

                                   ARTICLE IV
                                    Payments

     4.1 Application of Available Amounts. Until the date upon which the
Discharge of Senior Obligations shall have occurred, no payment (in cash,
property or securities (whether or not such securities are subordinated) or by
set off or otherwise) shall be made or agreed to be made by the Senior Borrower,
directly or indirectly, on account of any amounts (including any prepayments) in
respect of the Subordinated Obligations or as a redemption, retirement,


                                    Exh. F-14

<PAGE>

purchase, defeasance, prepayment or acquisition of any Subordination
Obligations, except from cash distributions to Subordinated Borrower pursuant to
the Senior Documents.

     4.2 Payments Over. Until the date upon which the Discharge of Senior
Obligations has occurred, any amounts received by the Subordinated Financing
Parties in contravention of this Agreement shall be segregated and held in trust
and forthwith paid over (a "Turnover Payment") to the Senior Agent for the
benefit of the Senior Financing Parties in the same form as received (without
recourse, representation or warranty (other than a representation of the
Subordinated Agent that it has not otherwise sold, assigned, transferred or
pledged any right, title or interest in and to such amount), with any necessary
endorsements or as a court of competent jurisdiction may otherwise direct to be
applied to the Senior Obligations. Until the date upon which the Discharge of
Senior Obligations shall have occurred, the Senior Agent is hereby authorized to
make any such endorsements as agent for the Subordinated Financing Parties.

     4.3 Distributions by Senior Borrower. The Senior Borrower agrees, for the
benefit of the Senior Financing Parties, that to the extent it is permitted to
make Distributions under the Senior Loan Agreement, it will make Distributions
to the Subordinated Borrower in the amounts and at the times required in order
to enable the Subordinated Borrower to pay interest due on the Subordinated
Loans, to make any mandatory prepayments of the Subordinated Loans required to
be made under the Senior Loan Agreement and to make any other payment required
to be made by the Subordinated Borrower under the Subordinated Documents.

                                    ARTICLE V
                                Other Agreements

     5.1 Amendments to Subordinated Documents. Until the date upon which the
Discharge of Senior Obligations shall have occurred, without the prior written
consent of the Senior Agent, no Subordinated Document may be amended,
supplemented or otherwise modified or entered into to the extent such amendment,
supplement or modification, or the terms of any new Subordinated Loan Agreement
or Subordinated Collateral Document, would contravene any of the terms of this
Agreement. The Subordinated Agent agrees that each Subordinated Collateral
Document shall include the following language:

          "Notwithstanding anything herein to the contrary, the lien and
     security interest granted to the administrative agent pursuant to this
     Agreement and the exercise of any right or remedy by the administrative
     agent hereunder are subject to the provisions of the Intercreditor
     Agreement, dated as of __________, 2006 (as amended, supplemented, and
     restated or otherwise modified from time to time, the "Intercreditor
     Agreement") among Dresdner Bank AG London Branch ("Dresdner"), in its
     capacity as Senior Agent (as defined therein) and as Subordinated Agent (as
     defined therein), The Gas Company, LLC, a Hawaii limited liability company,
     as Senior Borrower (as defined therein), and HGC Holdings, LLC, a Hawaii
     limited liability company, as Subordinated Borrower (as defined therein).
     In the event of any conflict between the terms of the Intercreditor
     Agreement and this Agreement, the terms of the Intercreditor Agreement
     shall govern."

     5.2 Amendments to Senior Documents. So long as no Event of Default (as
defined in the Senior Loan Agreement) has occurred and is continuing, the Senior
Financing Parties hereby agree with the Subordinated Financing Parties that the
Senior Financing Parties shall not, without the prior written consent of the
Required Subordinated Lenders which shall not be unreasonably withheld, amend or
waive any provision of, or consent to any amendment or waiver of, any of the
Senior Documents in a manner that could reasonably be expected to have a
material adverse effect on the Subordinated Financing Parties.

                                   ARTICLE VI
                             Bankruptcy Proceedings

     6.1 Financing and Sale Issues. If the Senior Borrower shall be subject to
any Bankruptcy Proceeding and at any time prior to the Discharge of Senior
Obligations the Senior Agent or the other Senior Financing Parties shall desire
to permit the sale, use or lease of cash collateral or to permit the Senior
Borrower to obtain financing under Section 363 or Section 364 of the Bankruptcy
Code or to provide such financing ("DIP Financing"), then, so long as (A) the
Subordinated Financing Parties retain the right to request a replacement Lien on
the assets covered by the Common Collateral with the same priority as existed
prior to the commencement of the Bankruptcy Proceeding (subject to the liens of
any DIP Financing Lender), (B) the material terms and conditions of such DIP
Financing (other than with respect to principal amount thereof) are commercially
reasonable, and (C) the Lien granted to the Person providing such financing
ranks prior to or pari passu with the pre-petition Lien of the Senior Financing
Parties, then the Subordinated Agent, on behalf of itself and the other
Subordinated Financing Parties, and each Subordinated Lender by becoming a
Subordinated Lender, agrees that it will raise no objection to, nor support any
other Person objecting to, such sale, use, or lease of cash collateral or DIP
Financing and will not request any form of adequate protection or any other
relief in connection therewith (except as agreed by the Senior Agent or to the
extent expressly permitted by Section 6.3) and, to the extent the Liens securing
the Senior Obligations are subordinate to or pari passu with such DIP Financing,
it will subordinate (and will be deemed hereunder to have subordinated) the
Liens securing the Subordinated Obligations (i) to such DIP Financing with, if
applicable, the same terms and conditions as the Liens securing the Senior
Obligations are subordinated thereto (and such subordination will not alter in
any manner the terms and priorities of this Agreement), (ii) to any adequate
protection provided to the Senior Financing Parties and (iii) to any "carve-out"
for reasonable professional and United States Trustee fees agreed to by the
Senior Financing Parties; provided that the foregoing shall not prohibit the
Subordinated Financing Parties from objecting solely to any provisions in any
DIP Financing relating to, describing or requiring any provision or content of a
plan of reorganization other than provisions solely requiring that the DIP
Financing be paid in full in cash. The Subordinated Agent, on behalf of itself
and the Subordinated Financing Parties, agrees that it will raise no objection
to or oppose a sale or other disposition of any Common Collateral free and clear
of its Liens or other claims under Section 363 of the Bankruptcy Code if the
Required Lenders have consented to such sale or disposition of such assets so
long as the respective interests of the Subordinated Financing Parties attach to
the proceeds thereof, subject to the terms of this Agreement, and (ii) the
material terms of such sale or disposition are commercially reasonable.

<PAGE>

     6.2 Relief from the Automatic Stay. Until the date upon which the Discharge
of Senior Obligations shall have occurred, the Subordinated Agent, on behalf of
itself and the other Subordinated Financing Parties, agrees that none of them
shall seek relief from the automatic stay or any other stay in any Bankruptcy
Proceeding in respect of any Common Collateral, without the prior written
consent of the Senior Agent and the Required Lenders.

     6.3 Adequate Protection. The Subordinated Agent, on behalf of itself and
the other Subordinated Financing Parties, agrees that none of them shall object,
contest, or support any other Person objecting to or contesting, (a) any request
by the Senior Financing Parties for adequate protection or (b) any objection by
the Senior Financing Parties to any motion, relief, action or proceeding based
on a claim of a lack of adequate protection or (c) the payment of interest,
fees, expenses or other amounts to the Senior Financing Parties under Section
506(b) or 506(c) of the Bankruptcy Code or otherwise. Notwithstanding anything
contained in this Section and in Section 6.1, in any Bankruptcy Proceeding, (i)
the Subordinated Financing Parties, may seek, support, accept or retain adequate
protection (A) only if the Senior Financing Parties are granted adequate
protection and (B) in the form of (x) a replacement Lien on such additional
collateral, subordinated to the Liens securing the Senior Obligations and such
DIP Financing on the same basis as the other Liens securing the Subordinated
Obligations are so subordinated to the Senior Obligations under this Agreement
and (y) superpriority claims junior in all respects to the superpriority claims
granted to the Senior Financing Parties, and (ii) in the event the Subordinated
Agent, on behalf of itself and the other Subordinated Financing Parties,
receives adequate protection, including in the form of additional collateral,
then the Subordinated Agent, on behalf of itself or any of the Subordinated
Financing Parties, agrees that the Senior Agent shall have a senior Lien and
claim on such adequate protection as security for the Senior Obligations and
that any Lien on any additional collateral securing the Subordinated Obligations
shall be subordinated to the Liens on such collateral securing the Senior
Obligations and any DIP Financing (and all Obligations relating thereto) and any
other Liens granted to the Senior Financing Parties as adequate protection, with
such subordination to be on the same terms that the other Liens securing the
Subordinated Obligations are subordinated to such Senior Obligations under this
Agreement. Notwithstanding the foregoing, (i) if the Senior Financing Parties
are deemed by a court of competent jurisdiction to be fully secured, then the
Subordinated Financing Parties shall not be prohibited from seeking adequate
protection in the form of interest, fees or other cash payments, except as
otherwise set forth in this Section 6.3 and (ii) if the Senior Financing Parties
object to the adequate protection being provided to the Senior Financing
Parties, the replacement Liens and superpriority claims granted to the
Subordinated Agent, on behalf of itself or any of the Subordinated Financing
Parties, shall be segregated and held in trust by the Subordinated Agent for the
benefit of the other Senior Financing Parties, pursuant to documents in form and
substance satisfactory to the Senior Agent, until the Discharge of Senior
Obligations shall have occurred.

     6.4 No Waiver. Nothing contained herein shall prohibit or in any way limit
the Senior Financing Parties from objecting in any Bankruptcy Proceeding or
otherwise to any action taken by the Subordinated Financing Parties, including
the seeking by the Subordinated Financing Parties of adequate protection or the
asserting by the Subordinated Financing Parties of any of its rights and
remedies under the Subordinated Documents or otherwise, unless, in each case,
such action is consistent with the terms of this Section 6.

     6.5 Preference Issues. If any Senior Financing Party is required in any
Bankruptcy Proceeding or otherwise to turn over or otherwise pay to the estate
of the Senior Borrower any amount (whether received by or on behalf of the
Senior Borrower, as proceeds of security, enforcement of any right of setoff or
otherwise) (a "Recovery"), then the obligation or part thereof originally
intended to be satisfied shall be reinstated and outstanding as Senior
Obligations, as of the date of such Recovery to the extent of such Recovery and
the Discharge of Senior Obligations shall be deemed not to have occurred, except
to the extent such turnover obligation arose from an Improper Act. If this
Agreement shall have been terminated prior to such Recovery, this Agreement
shall be reinstated in full force and effect, and such prior termination shall
not diminish, release, discharge, impair or otherwise affect the obligations of
the parties hereto from such date of reinstatement. The Subordinated Financing
Parties agree that none of them shall be entitled to benefit from any avoidance
action affecting or otherwise relating to any distribution or allocation made in
accordance with this Agreement, whether by preference or otherwise, it being
understood and agreed that the benefit of such avoidance action otherwise
allocable to them shall instead be allocated and turned over for application in
accordance with the priorities set forth in this Agreement, subject to Section
4.2 and except to the extent such turnover obligation arose from an Improper
Act. In the event that any such payment with respect to the Senior Obligations
results in a Discharge of Senior Obligations, the Senior Financing Parties agree
that the Subordinated Financing Parties shall be permitted to act hereunder as
though a Discharge of Senior Obligations had occurred during the period from
such payment until the date of such reinstatement of the Senior Obligations and
shall have no liability to the Senior Financing Parties for any action taken or
omitted to be taken hereunder in accordance therewith, except to the extent such
act or omission is found by a final, non-appealable judgment of a court of
competent jurisdiction to arise from the gross negligence, bad faith or willful
misconduct of the Subordinated Financing Parties.

     6.6 Reorganization Securities. If, in any Bankruptcy Proceeding, debt
instruments or securities of the reorganized debtor secured by Liens upon any
property of the reorganized debtor are distributed, pursuant to a
court-authorized plan of reorganization or similar court-authorized dispositive
restructuring plan, both on account of Senior Obligations and on account of
Subordinated Obligations, then, to the extent the debt instruments or securities
distributed on account of the Senior Obligations and on account of the
Subordinated Obligations are secured by Liens upon the same property, the
provisions of this Agreement will survive the distribution of such debt
instruments or securities pursuant to such plan and will apply with like effect
to the Liens securing such debt instruments or securities.

     6.7 Separate Grants of Security and Separate Classification. The
Subordinated Agent on behalf of itself and the other Subordinated Financing
Parties acknowledges and agrees that (a) the grants of Liens pursuant to the
Senior Collateral Documents and the Subordinated Collateral Documents constitute
two separate and distinct grants of Liens; and (b) because of, among other
things, their differing rights in the Common Collateral, the Subordinated
Obligations are fundamentally different from the Senior Obligations and must be
separately classified in any plan of reorganization proposed or adopted in a
Bankruptcy Proceeding. To further effectuate the intent of the parties as
provided in the immediately preceding sentence, if it is held that the claims of
the Senior Financing Parties and the Subordinated Financing Parties in respect
of the Common Collateral constitute only one secured claim (rather than separate


                                    Exh. F-18

<PAGE>

classes of senior and junior secured claims), then the Subordinated Agent on
behalf of itself and the other Subordinated Financing Parties hereby
acknowledges and agrees that all distributions shall be made as if there were
separate classes of senior and junior secured claims against the Borrowers in
respect of the Common Collateral (with the effect being that, to the extent that
the aggregate value of the Common Collateral is sufficient (for this purpose
ignoring all claims held by the Subordinated Financing Parties), the Senior
Financing Parties shall be entitled to receive, in addition to amounts
distributed to them in respect of principal, pre-petition interest and other
claims, all amounts owing in respect of post-petition interest before any
distribution is made in respect of the claims held by the Subordinated Financing
Parties, with the Subordinated Financing Parties hereby acknowledging and
agreeing to turn over to the Senior Financing Parties amounts otherwise received
or receivable by them to the extent necessary to effectuate the intent of this
sentence, even if such turnover has the effect of reducing the claim or recovery
of the Subordinated Financing Parties).

     6.8 Effectiveness in Bankruptcy Proceedings. This Agreement, which the
parties hereto expressly acknowledge is a "subordination agreement" under
Section 510(a) of the Bankruptcy Code, shall be effective before, during and
after the commencement of a Bankruptcy Proceeding. All references in this
Agreement to a Borrower shall include such Person as a debtor-in-possession and
any receiver or trustee for such Person in any Bankruptcy Proceeding.

                                   ARTICLE VII
                           Reliance; Waivers; Notices

     7.1 Reliance.

          (a) The consent by the Senior Financing Parties to the execution and
     delivery of the Subordinated Documents and the grant to the Subordinated
     Agent on behalf of itself and the other Subordinated Financing Parties of a
     Lien on the Common Collateral and all loans and other extensions of credit
     made or deemed made on and after the date hereof by the Senior Financing
     Parties to any Borrower shall be deemed to have been given and made in
     reliance upon this Agreement. The Subordinated Agent, on behalf of itself
     and the other Subordinated Financing Parties, acknowledges that it and the
     other Subordinated Financing Parties have, independently and without
     reliance on the Senior Agent or any other Senior Financing Party, and based
     on documents and information deemed by them appropriate, made their own
     credit analysis and decision to enter into the Subordinated Loan Agreement,
     the other Subordinated Documents, this Agreement and the transactions
     contemplated hereby and thereby and they will continue to make their own
     credit decision in taking or not taking any action under the Subordinated
     Loan Agreement, the other Subordinated Documents or this Agreement.

          (b) The consent by the Subordinated Financing Parties to the execution
     and delivery of the Senior Documents and the grant to the Senior Agent on
     behalf of itself and the other Senior Financing Parties of a Lien on the
     Common Collateral and all loans and other extensions of credit made or
     deemed made on and after the date hereof by

<PAGE>

     the Subordinated Financing Parties to any Borrower shall be deemed to have
     been given and made in reliance upon this Agreement. The Senior Agent, on
     behalf of itself and the other Senior Financing Parties, acknowledges that

remedies in favor of the Senior Agent in any other Loan Document shall not be
deemed a conflict with this Agreement. Each Loan Document was drafted with the
joint participation of the respective parties thereto and shall be construed
neither against nor in favor of any party, but rather in accordance with the
fair meaning thereof

     8.22 Severability. If any provision of this Agreement is held to be
illegal, invalid or unenforceable, (a) the legality, validity and enforceability
of the remaining provisions of this Agreement shall not be affected or impaired
thereby and (b) the parties shall endeavor in good faith negotiations to replace
the illegal, invalid or unenforceable provisions with valid provisions the
economic effect of which comes as close as possible to that of the illegal,
invalid or unenforceable provisions. The invalidity of a provision in a
particular jurisdiction shall not invalidate or render unenforceable such
provision in any other jurisdiction.

     8.23 Headings. The table of contents and the headings of Articles and
Sections have been included herein for convenience of reference only, are not
part of this Agreement, and shall not be taken into consideration in
