    (b)  Method of Borrowing.

                  Agent not later than 11:00 A.M. (New York City time) on the
                  Business Day prior to the date of the proposed Borrowing. Each
                  such notice (a "Notice of Borrowing") shall be in
                  substantially the form of Exhibit B, specifying therein (a)
                  the date of such proposed Borrowing and (b) the aggregate
                  amount of such proposed Borrowing, accompanied by a

<PAGE>

         (a)      Funding by Lenders. Each Lender shall, before 11:00 A.M. (New
                  York City time) on the date of the proposed Borrowing, make
                  available to the Administrative Agent at its address referred
                  to in Section 11.01, in immediately available funds, such
                  Lender's Ratable Portion of such proposed Borrowing. After the
                  Administrative Agent's receipt of such funds and upon
                  fulfillment of the applicable conditions set forth in Article
                  III, the Administrative Agent will make such funds available
                  to the Borrower.

         (b)      Presumption by the Administrative Agent. Unless the
                  Administrative Agent shall have received notice from a Lender
                  prior to the date of any proposed Borrowing that such Lender
                  will not make available to the Administrative Agent such
                  Lender's Ratable Portion of such Borrowing, the Administrative
                  Agent may assume that such Lender has made such Ratable
                  Portion available to the Administrative Agent on the date of
                  such Borrowing in accordance with this Section 2.03, and the
                  Administrative Agent may, in reliance upon such assumption,
                  make available to the Borrower on such date a corresponding
                  amount. If and to the extent that such Lender shall not have
                  so made such Ratable Portion available to the Administrative
                  Agent, such Lender and the Borrower severally agree to repay
                  to the Administrative Agent forthwith on demand such
                  corresponding amount together with interest thereon, for each
                  day from the date such amount is made available to the
                  Borrower until the date such amount is repaid to the
                  Administrative Agent, at (i) in the case of the Borrower, the
                  interest rate applicable at the time to the Loans comprising
                  such Borrowing and (ii) in the case of such Lender, the
                  Federal Funds Rate. If such Lender shall repay to the
                  Administrative Agent such corresponding amount, such amount so
                  repaid shall constitute such Lender's Loan as part of such
                  Borrowing for purposes of this Agreement. If the Borrower
                  shall repay to the Administrative Agent such corresponding
                  amount, such payment shall not relieve such Lender of any
                  obligation it may have to the Borrower hereunder.

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

         (d)      Repayment.

                  The Borrower shall repay the entire unpaid principal amount
of the Loans on the Maturity Date.

                                       16
<PAGE>

         (a)      Optional Prepayments. The Borrower may, upon at least one
                  Business Day's prior notice to the Administrative Agent,
                  stating the proposed date and aggregate principal amount of
                  the prepayment, prepay the outstanding principal amount of the
                  Loans in whole or ratably in part, together with accrued
                  interest to the date of such prepayment on the principal
                  amount prepaid; provided, however, that each partial
                  prepayment shall be in an aggregate principal amount not less
                  than $1,000,000 or integral multiples of $1,000,000 in excess
                  thereof. Upon the giving of such notice of prepayment, the
                  principal amount of the Loans specified to be prepaid shall
                  become due and payable on the date specified for such
                  prepayment.

         (b)      Mandatory Prepayments.

                  (a)      If at any time the aggregate principal amount of
                           Loans outstanding shall exceed the aggregate
                           Commitments, the Borrower shall immediately prepay
                           the Loans then outstanding in an amount equal to such
                           excess together with accrued interest thereon.

                  (b)      The Borrower shall prepay the Loans in an amount
                           equal to the Net Cash Proceeds of any Divestiture
                           completed in accordance with Section 6.03(b), within
                           one Business Day after receipt of such Net Cash
                           Proceeds.

    (f)  Notes.

         The obligation of the Borrower to repay the Loans made by each Lender
and to pay interest thereon at the rates provided herein shall be further
evidenced by a promissory note, substantially in the form of Exhibit A (each, a
"Note" and collectively, the "Notes"), payable to the order of such Lender and
in the principal amount of such Lender's initial Commitment. The Borrower
authorizes each Lender to record on the schedule annexed to such Lender's Note,
the date and amount of each Loan made by such Lender, and each payment or
prepayment of principal thereunder and agrees that all such notations shall
constitute prima facie evidence of the matters noted. The Borrower further
authorizes each Lender to attach to and make a part of such Lender's Note
continuations of the schedule attached thereto as necessary. No failure to make
any such notations, nor any errors in making any such notations, shall affect
the validity of the Borrower's obligations to repay the full unpaid principal

    (g)  Reduction and Expiration of Commitments.

         (a)      The Commitments shall expire on the last day of the
                  Availability Period if not utilized prior to such date.

         (b)      The Borrower may, upon at least five Business Days' prior
                  notice to the Administrative Agent, terminate in whole or
                  reduce ratably in part the unused portions of the respective
                  Commitments of the Lenders; provided, however, that each
                  partial reduction shall be in the aggregate amount of not less
                  than $1,000,000 or an integral multiple of $1,000,000 in
                  excess thereof.

         (c)      The Commitments shall be automatically and permanently reduced
                  by an amount equal to the amount of any prepayment required by
                  Section 2.05(b)(ii) in connection with any Divestiture to the
                  extent that the aggregate amount of Net Cash Proceeds received
                  from all Divestitures from and after the Closing Date exceeds
                  $500,000.

    (h)  Fees.

         (a)      Unused Commitment Fee. The Borrower agrees to pay to the
                  Administrative Agent, for the account of each Lender, an
                  unused commitment fee on the average daily unused portion of
                  such Lender's Commitment at the rate of 0.50% per annum,
                  payable in arrears on (i) the last day of each fiscal quarter
                  and (ii) the last day of the Availability Period.

         (b)      Up-Front Fee. The Borrower shall pay to the Administrative
                  Agent, for the account of each Lender party hereto on the date
                  hereof, on the Closing Date in immediately available funds, a
                  one-time, up-front fee equal to 3.0% of the aggregate
                  Commitments of all of the Lenders.

         (c)      Additional Commitment Fee. In the event a plan of
                  reorganization acceptable to the Lenders, the Bond Support
                  Lenders and the Bank Lenders has not been (i) confirmed within
                  five months after the Filing Date and/or (ii) consummated
                  within six months after the Filing Date, the Borrower shall
                  pay to the Administrative Agent, for the ratable account of
                  each Lender, on the first Business Day after such date, in
                  immediately available funds, a one-time fee equal to $900,000.

         (d)      Payment of Fees. All fees payable hereunder shall be paid on
                  the dates due, in immediately available funds, to the
                  Administrative Agent for distribution, in the case of the fees
                  set forth in clauses (a), (b) and (c), to the Persons entitled
                  thereto. Fees paid hereunder shall not be refundable under any
                  circumstances.

    (i)  Interest.

         The Borrower shall pay interest on the unpaid principal amount of each
Loan from the date thereof until the principal amount thereof shall be paid in
full, at a rate per annum equal at all times to the Prime Rate in effect from
time to time plus 3.0% per annum, payable quarterly in arrears on the last day
of each fiscal quarter and on the date any Loan is or is to be paid or prepaid,
in whole or in part; provided, however, that during the continuance of an Event
of Default, all Loans shall bear interest, payable on demand, at a rate per
annum equal at all times to the Prime Rate then in effect plus 5.0% per annum.
The Administrative Agent shall give prompt notice to the Borrower and the
Lenders of the applicable interest rate determined by the Administrative Agent
for purposes of this Section 2.09.

    (j)  Capital Adequacy.

         If after the date hereof, (a) the introduction of or any change in or
in the interpretation of any law or regulation, (b) compliance with any law or
regulation, or (c) compliance with any guideline or request from any central
bank or other Governmental Authority (whether or not having the force of law)
affects or would affect the

                                       18
<PAGE>

amount of capital required or expected to be maintained by any Lender or any
corporation controlling any Lender and such Lender reasonably determines that
such amount is based upon the existence of such Lender's Commitments, Loans and
its other commitments and loans of similar type, then, within ten Business Days
after demand by such Lender (with a copy of such demand to the Administrative
Agent), the Borrower shall pay to the Administrative Agent for the account of
such Lender, from time to time as specified by such Lender, additional amounts
sufficient to compensate such Lender in the light of such circumstances, to the
extent that such Lender reasonably determines such increase in capital to be
allocable to the existence of any or all of such Lender's Commitments and Loans.
A certificate containing reasonably detailed calculations of such amounts
submitted to the Borrower and the Administrative Agent by such Lender shall be
conclusive and binding for all purposes absent manifest error.

    (k)  Increased Costs.

         If, due to either (a) the introduction of or any change in or in the
interpretation of any law or regulation or (b) compliance with any guideline or
request from any central bank or other Governmental Authority (whether or not
having the force of law), there shall be any increase in the cost to any Lender
of agreeing to make or making, funding or maintaining any Loans, then the
Borrower shall from time to time, within ten Business Days after demand by such
Lender (with a copy of such demand to the Administrative Agent), pay to the
Administrative Agent for the account of such Lender additional amounts
sufficient to compensate such Lender for such increased cost. A certificate
containing reasonably detailed calculations of the amount of such increased
cost, submitted to the Borrower and the Administrative Agent by such Lender,
shall be conclusive and binding for all purposes, absent manifest error.

    (l)  Payments and Computations.

         (a)      The Borrower shall make each payment hereunder and under the
                  Notes not later than 11:00 A.M. (New York City time) on the
                  day when due, in Dollars, to the Administrative Agent at its
                  address referred to in Section 11.01 in immediately available
                  funds without set-off or counterclaim. The Administrative
                  Agent will promptly thereafter cause to be distributed
                  immediately available funds relating to the payment of
                  principal, interest or fees (other than amounts payable
                  pursuant to Sections 2.10, 2.11 and 2.13) to the Lenders, in
                  accordance with their respective Ratable Portions, and like
                  funds relating to the payment of any other amount payable to
                  any Lender to such Lender, in each case to be applied in
                  accordance with the terms of this Agreement. Payment received
                  by the Administrative Agent after 11:00 A.M. (New York City
                  time) shall be deemed to be received on the next Business Day.

         (b)      The Borrower hereby authorizes each Lender, if and to the
                  extent payment owed to such Lender is not made when due
                  hereunder or under any Loan held by such Lender, to charge
                  from time to time against any or all of the Borrower's
                  accounts with such Lender any amount so due.

         (c)      All computations of interest based on the Prime Rate or the
                  Federal Funds Rate and of fees shall be made by the
                  Administrative Agent on the basis of a year of 365 or 366
                  days, as the case may be, for the actual number of days
                  (including the first day but excluding the last day) occurring
                  in the period for which such interest or fees are payable.
                  Each determination by the Administrative Agent of an interest
                  rate hereunder shall be conclusive and binding for all
                  purposes, absent manifest error.

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

         (e)      Unless the Administrative Agent shall have received notice
                  from the Borrower prior to the date on which any payment is
                  due hereunder to the Lenders that the Borrower will not make
                  such payment in

                                       19
<PAGE>

                  full, the Administrative Agent may assume that the Borrower
                  has made such payment in full to the Administrative Agent on
                  such date, and the Administrative Agent may, in reliance upon
                  such assumption, cause to be distributed to each Lender on
                  such due date an amount equal to the amount then due such
                  Lender. If and to the extent the Borrower shall not have so
                  made such payment in full to the Administrative Agent, each
                  Lender shall repay to the Administrative Agent forthwith on
                  demand such amount distributed to such Lender together with
                  interest thereon, for each day from the date such amount is
                  distributed to such Lender until the date such Lender repays
                  such amount to the Administrative Agent, at the Federal Funds
                  Rate.

    (m)  Taxes.

         (a)      Any and all payments by the Borrower under each Credit
                  Document shall be made free and clear of and without deduction
                  for any and all present or future taxes, levies, imposts,
                  deductions, charges or withholdings, and all liabilities with
                  respect thereto, excluding, in the case of the Administrative
                  Agent, taxes measured by its net income and franchise taxes
                  (imposed in lieu of a tax on net income) imposed on it by each
                  jurisdiction under the laws of which the Administrative Agent
                  is organized or any political subdivision thereof and, in the
                  case of each Lender, taxes measured by its net income and
                  franchise taxes (imposed in lieu of a tax on net income)
                  imposed on it by each jurisdiction under the laws of which
                  such Lender is organized or any political subdivision thereof
                  (all such non-excluded taxes, levies, imposts, deductions,
                  charges, withholdings and liabilities being hereinafter
                  referred to as "Taxes"). If the Borrower shall be required by
                  law to deduct or withhold any Taxes from or in respect of any
                  sum payable hereunder to any Lender or the Administrative
                  Agent (i) the sum payable shall be increased as may be
                  necessary so that after making all required deductions or
                  withholdings (including, without limitation, deductions or
                  withholdings applicable to additional sums payable under this
                  Section 2.13) such Lender or the Administrative Agent, as the
                  case may be, receives an amount equal to the sum it would have
                  received had no such deductions or withholdings been made,
                  (ii) the Borrower shall make such deductions or withholdings,
                  and (iii) the Borrower shall pay the full amount deducted or
                  withheld to the relevant taxing authority or other authority
                  in accordance with applicable law.

         (b)      In addition, the Borrower agrees to pay any present or future
                  stamp or documentary taxes or any other excise or property
                  taxes, charges or similar levies of any applicable
                  Governmental Authority which arise from any payment made under
                  any Credit Document or from the execution, delivery or
                  registration of, or otherwise with respect to, any Credit
                  Document (collectively, "Other Taxes").

         (c)      The Borrower will indemnify each Lender and the Administrative
                  Agent for the full amount of Taxes or Other Taxes (including,
                  without limitation, any Taxes or Other Taxes imposed by any
                  jurisdiction on amounts payable under this Section 2.13) paid
                  by such Lender or the Administrative Agent, as the case may
                  be, and any liability (including, without limitation, for
                  penalties, interest and expenses) arising therefrom or with
                  respect thereto, whether or not such Taxes or Other Taxes were
                  correctly or legally asserted. This indemnification shall be
                  made within 30 days from the date such Lender or the
                  Administrative Agent, as the case may be, makes written demand
                  therefor.

         (d)      Within 30 days after the date of any payment of Taxes or Other
                  Taxes, the Borrower will furnish to the Administrative Agent,
                  at its address referred to in Section 11.01, the original or a
                  certified copy of a receipt evidencing payment thereof.

         (e)      Without prejudice to the survival of any other agreement of
                  the Borrower hereunder, the agreements and obligations of the
                  Borrower contained in this Section 2.13 shall survive the
                  payment in full of the Obligations.

         (f)      Any Lender that is a United States person under Section
                  7701(a)(30) of the Code for U.S. Federal income tax purposes
                  shall deliver to the Borrower and the Administrative Agent at
                  the time or times

                                       20
<PAGE>

                  prescribed by applicable law or reasonably requested by the
                  Borrower a properly completed and executed Internal Revenue
                  Service Form W-9 (or any subsequent versions thereof or
                  successors thereto). Any Lender that is not a United States
                  person under Section 7701(a)(30) of the Code for U.S. Federal
                  income tax purposes that is entitled to an exemption from or
                  reduction of withholding tax under the laws of the United
                  States of America, or any treaty to which the United States of
                  America is a party, with respect to payments under any Credit
                  Document shall deliver to the Borrower and the Administrative
                  Agent, at the time or times prescribed by applicable law or
                  reasonably requested by the Borrower, such properly completed
                  and executed documentation prescribed by applicable law as
                  will permit such payments to be made without withholding or at
                  a reduced rate.

         (g)      In those circumstances as shall be necessary under applicable
                  law to allow payments hereunder to be made free of (or at a
                  reduced rate of) United States withholding tax, at the written
                  request of the Borrower, the Administrative Agent shall
                  provide the Borrower with (i) two properly completed and
                  executed originals of IRS Form W-8IMY (or any subsequent
                  versions thereof or successors thereto) with respect to its
                  exemption from United States withholding tax because it is a
                  U.S. branch of a foreign bank and (ii) such documentation as
                  shall have been received from the Lenders by the
                  Administrative Agent but not the Borrower pursuant to
                  subparagraph (f) of this Section.

    (n)  Sharing of Payments, Etc.

         If any Lender shall obtain any payment (whether voluntary, involuntary,
through the exercise of any right of set-off, or otherwise) on account of the
Loans made by it (other than pursuant to Section 2.10, 2.11, or 2.13) in excess
of its Ratable Portion of payments on account of the Loans obtained by all the
Lenders, such Lender shall forthwith purchase from the other Lenders such
participations in their Loans as shall be necessary to cause such purchasing
Lender to share the excess payment ratably with each of them; provided, however,
that if all or any portion of such excess payment is thereafter recovered from
such purchasing Lender, such purchase from each Lender shall be rescinded, and
such Lender shall repay to the purchasing Lender the purchase price to the
extent of such recovery together with an amount equal to such Lender's ratable
share (according to the proportion of (a) the amount of such Lender's required
repayment to (b) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered. The Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section 2.14
may, to the fullest extent permitted by law, exercise all its rights of payment
(including, without limitation, the right of set-off) with respect to such
participation as fully as if such Lender were the direct creditor of the
Borrower in the amount of such participation.

further material tax liability with respect to any open taxable years taken as a
whole in excess of accrued amounts.

                  event or condition has occurred or exists as a result of which

                  respect to any Plan; (ii) no "accumulated funding deficiency,"
                  as such term is defined in Section 302 of ERISA and Section
                  412 of the Internal Revenue Code, whether or not waived, has
                  occurred with respect to any Plan; (iii) each Plan has been
                  maintained, operated, and funded in compliance with its own
                  terms and in material compliance with the provisions of ERISA,

                  state laws; and (iv) no lien in favor of the PBGC or a Plan
                  has arisen or is reasonably likely to arise on account of any
                  Plan.

         (b)      The actuarial present value of all "benefit liabilities" (as
                  defined in Section 4001(a)(16) of ERISA), whether or not
                  vested, under each Single Employer Plan, as of the last annual
                  valuation date prior to the date on which this representation
                  is made or deemed made (determined, in each case, in
                  accordance with Financial Accounting Standards Board Statement
                  87, utilizing the actuarial assumptions used in such Plan's
                  most recent actuarial valuation report), did not exceed as of
                  such valuation date the fair market value of the assets of
                  such Plan.

         (c)      Neither any Credit Party nor any ERISA Affiliate has incurred,
                  or, to the best knowledge of the Credit Parties, could be
                  reasonably expected to incur, any withdrawal liability under
                  ERISA to any Multiemployer Plan or Multiple Employer Plan.
                  Neither any Credit Party nor any ERISA Affiliate would become

                  Affiliate were to withdraw completely from all Multiemployer
                  Plans and Multiple Employer Plans as of the valuation date
                  most closely preceding the date on which this representation
                  is made or deemed made. Neither any Credit Party nor any ERISA
                  Affiliate has received any notification that any Multiemployer
                  Plan is in reorganization (within the meaning of Section 4241
                  of ERISA), is insolvent (within the meaning of Section 4245 of
                  ERISA), or has been terminated (within the meaning of Title IV
                  of ERISA), and no Multiemployer Plan is, to the best knowledge
                  of the Credit Parties, reasonably expected to be in
                  reorganization, insolvent, or terminated.

         (d)      No prohibited transaction (within the meaning of Section 406
                  of ERISA or Section 4975 of the Internal Revenue Code) or
                  breach of fiduciary responsibility has occurred with respect
                  to a Plan which has subjected or may subject any Credit Party
                  or any ERISA Affiliate to any liability under Sections 406,
                  409, 502(i), or 502(l) of ERISA or Section 4975 of the
                  Internal Revenue Code, or under any agreement or other
                  instrument pursuant to which any Credit Party or any ERISA
                  Affiliate has agreed or is required to indemnify any person
                  against any such liability.

         (e)      Neither any Credit Party nor any ERISA Affiliates has any
                  material liability with respect to "expected post-retirement
                  benefit obligations" within the meaning of the Financial
                  Accounting Standards Board Statement 106. Each Plan which is a
                  welfare plan (as defined in Section 3(1) of ERISA) to which
                  Sections 601-609 of ERISA and Section 4980B of the Internal
                  Revenue Code apply has been administered in compliance in all
                  material respects of such sections.

         (f)      Neither the execution and delivery of this Agreement nor the
                  consummation of the financing transactions contemplated
                  thereunder will involve any transaction which is subject to
                  the prohibitions of Sections 404, 406 or 407 of ERISA or in
                  connection with which a tax could be imposed pursuant to
                  Section 4975 of the Internal Revenue Code. The representation
                  by the Credit Parties in the preceding sentence is made in
                  reliance upon and subject to the accuracy of the Lenders'
                  representation in Section 11.15 with respect to their source
                  of funds and is subject, in the event that the source of the
                  funds used by the Lenders in connection with this transaction
                  is an insurance company's general asset account, to the
                  application of Prohibited Transaction Class Exemption 95-60,
                  60 Fed. Reg. 35,925 (1995), compliance with the regulations
                  issued under Section 401(c)(1)(A) of ERISA, or the issuance of
                  any other prohibited transaction exemption or similar relief,
                  to the effect that assets in an insurance company's general
                  asset account do not constitute assets of an "employee benefit
                  plan" within the meaning of Section 3(3) of ERISA or a "plan"
                  within the meaning of Section 4975(e)(1) of the Internal
                  Revenue Code.

                  Agreement (including, without limitation, the direct or

                  result in a violation of the Securities Act of 1933, as
                  amended or the Exchange Act, or regulations issued pursuant
                  thereto, or Regulation T, U or X.

                  Bankruptcy Court confirming a plan of reorganization or
                  liquidation in the Bankruptcy Cases which does not contain a
                  provision for termination of all of the Commitments and
                  payment in full in cash of the Obligations on or before the
                  effective date of such plan.

    (b)  Acceleration; Remedies.

         Upon the occurrence and during the continuation of an Event of Default,
without further order of, application to, or action by the Bankruptcy Court, the
Administrative Agent (a) may, and shall upon the request of the Majority
Lenders, by written notice to the Borrower declare that all or any portion of
the Commitments be terminated, whereupon the obligation of each Lender to make
any Loan shall immediately terminate, and/or (b) may, and shall upon the request
of the Majority Lenders, by written notice to the Borrower declare the Loans,
all interest thereon and all other amounts and Obligations payable under this
Agreement to be forthwith due and payable, whereupon the Loans, all such
interest, and all such amounts and Obligations shall become and be forthwith due
and payable, without presentment, demand, protest or other notice of any kind,
all of which are hereby waived by the Borrower. In addition, subject solely to
any requirement of the giving of notice by the terms of the Interim DIP
Financing Order or the Final DIP Financing Order, the automatic stay provided in
Section 362 of the Bankruptcy Code shall be automatically vacated without
further action or order of the Bankruptcy Court, and the Administrative Agent
and the Lenders shall be entitled to exercise all of their respective rights and
remedies under the Credit Documents and applicable law, including without
limitation, all rights and remedies with respect to the Collateral and the
Guarantors.

Item 47.

GUARANTY

    (a)  The Guarantee.

         (a)      (i) Each of the Guarantors hereby jointly and severally
                  guarantees to each Lender and to the Administrative Agent, as
                  hereinafter provided, the prompt payment of the Guaranteed
                  Obligations in full when due (whether at stated maturity, as a
                  mandatory prepayment, by acceleration, as a mandatory cash
                  collateralization or otherwise) strictly in accordance with
                  the terms thereof. The Guarantors hereby further agree that if
                  any of the Guaranteed Obligations are not paid in full when
                  due (whether at stated maturity, as a mandatory prepayment, by
                  acceleration, as a mandatory cash collateralization or
                  otherwise), the Guarantors will, jointly and severally,
                  promptly pay the same, without any demand or notice
                  whatsoever, and that in the case of any extension of time of
                  payment or renewal of any of the Guaranteed Obligations, the
                  same will be promptly paid in full when due (whether at
                  extended maturity, as a mandatory prepayment, by acceleration,
                  as a mandatory cash collateralization or otherwise) in
                  accordance with the terms of such extension or renewal.

         (b)      Notwithstanding any provision to the contrary contained herein
                  or in any of the other Credit Documents, to the extent the
                  obligations of a Guarantor shall be adjudicated to be invalid
                  or unenforceable for any reason (including, without
                  limitation, because of any applicable state, provincial or
                  Federal law relating to fraudulent conveyances or transfers or
                  the granting of financial assistance) then the obligations of
                  each Guarantor hereunder shall be limited to the maximum
                  amount that is permissible under applicable law (whether
                  Federal, state or provincial and including, without
                  limitation, the Bankruptcy Code). In such case or otherwise at
                  the request of the Administrative Agent, each Credit Party
                  shall take such action and shall execute and deliver all such
                  further documents required by the Administrative Agent to
                  cause the obligations of such Guarantor to be enforceable to
                  the extent required by this Agreement.

    (b)  Obligations Unconditional.

         The obligations of the Guarantors under Section 8.01 are joint and
several, absolute and unconditional, irrespective of the value, genuineness,
validity, regularity or enforceability of any of the Credit Documents or any
other agreement or instrument referred to therein, or any substitution, release
or exchange of any other guarantee of or security for any of the Guaranteed
Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Section 8.02 that the obligations of each of the
Guarantors hereunder shall be absolute and unconditional under any and all
circumstances. Each Guarantor agrees that such Guarantor shall have no right of
subrogation, indemnity, reimbursement or contribution against the Borrower or
any other Guarantor for amounts paid under this Article VIII until such time as
all of the Lenders have been paid in full, all of the Commitments under the
Agreement have been terminated and no Person or Governmental Authority shall
have any right to request any return or reimbursement of funds from the Lenders
in connection with monies received under the Credit Documents. Without limiting
the generality of the foregoing, it is agreed that, to the fullest extent
permitted by law, the occurrence of any one or more of the following shall not
alter or impair the liability of any Guarantor hereunder which shall remain
absolute and unconditional as described above:

                                       49
<PAGE>

                  (a)      at any time or from time to time, without notice to
                           any Guarantor, the time for any performance of or
                           compliance with any of the Guaranteed Obligations
                           shall be extended, or such performance or compliance
                           shall be waived;

                  (b)      any of the acts mentioned in any of the provisions of
                           any of the Credit Documents or any other agreement or
                           instrument referred to in the Credit Documents shall
                           be done or omitted;

                  (c)      the maturity of any of the Guaranteed Obligations
                           shall be accelerated, or any of the Guaranteed
                           Obligations shall be modified, supplemented or
                           amended in any respect, or any right under any of the
                           Credit Documents or any other agreement or instrument
                           referred to in the Credit Documents shall be waived
                           or any other guarantee of any of the Guaranteed
                           Obligations or any security therefor shall be
                           released or exchanged in whole or in part or
                           otherwise dealt with;

                  (d)      any Lien granted to, or in favor of, the
                           Administrative Agent or any Lender or Lenders, as
                           security for any of the Guaranteed Obligations shall
                           fail to attach or be perfected; or

                  (e)      any of the Guaranteed Obligations shall be determined
                           to be void or voidable (including, without
                           limitation, for the benefit of any creditor of any
                           Guarantor) or shall be subordinated to the claims of
                           any Person (including, without limitation, any
                           creditor of any Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that the Administrative Agent or any Lender
exhaust any right, power or remedy or proceed against any Person under any of
the Credit Documents or any other agreement or instrument referred to in the
Credit Documents, or against any other Person under any other guarantee of, or
security for, any of the Guaranteed Obligations.

    (c)  Reinstatement.

         (a)      The obligations of the Guarantors under this Article VIII
                  shall be automatically reinstated if and to the extent that
                  for any reason any payment by or on behalf of any Person in
                  respect of the Guaranteed Obligations is rescinded or must be
                  otherwise restored by any holder of any of the Guaranteed
                  Obligations, whether as a result of any proceedings in
                  bankruptcy or reorganization or otherwise, and each Guarantor
                  agrees that it will indemnify the Administrative Agent and
                  each Lender on demand for all reasonable costs and expenses
                  (including, without limitation, reasonable fees and expenses
                  of counsel) incurred by the Administrative Agent or such
                  Lender in connection with such rescission or restoration,
                  including any such costs and expenses incurred in defending
                  against any claim alleging that such payment constituted a
                  preference, fraudulent transfer or similar payment under any
                  bankruptcy, insolvency or similar law.

    (d)  Certain Additional Waivers.

         Each Guarantor agrees that such Guarantor shall have no right of
recourse to security for the Guaranteed Obligations, except through the exercise
of the rights of subrogation pursuant to Section 8.02.

    (e)  Remedies.

         The Guarantors agree that, to the fullest extent permitted by law, as
between the Guarantors, on the one hand, and the Administrative Agent and the
Lenders, on the other hand, the Guaranteed Obligations may be declared to be
forthwith due and payable as provided in Section 7.02 (and shall be deemed to
have become automatically due and payable in the circumstances provided in said
Section 7.02) for purposes of Section 8.01 notwithstanding any stay, injunction
or other prohibition preventing such declaration (or preventing the Guaranteed
Obligations from becoming automatically due and payable) as against any other
Person and that, in the event of such declaration (or the Guaranteed Obligations
being deemed to have become automatically due and payable), the Guaranteed

                                       50
<PAGE>

Obligations (whether or not due and payable by any other Person) shall forthwith
become due and payable by the Guarantors for purposes of Section 8.01.

    (f)  Rights of Contribution.

         The Guarantors hereby agree, as among themselves, that if any Guarantor
shall become an Excess Funding Guarantor, each other Guarantor shall, on demand
of such Excess Funding Guarantor (but subject to the succeeding provisions of
this Section 8.06), pay to such Excess Funding Guarantor an amount equal to such
Guarantor's Pro Rata Share (as defined below and determined, for this purpose,
without reference to the Facilities, assets, liabilities and debts of such
Excess Funding Guarantor) of such Excess Payment (as defined below). The payment
obligation of any Guarantor to any Excess Funding Guarantor under this Section
8.06 shall be subordinate and subject in right of payment to the prior payment
in full of the obligations of such Guarantor under the other provisions of this
Article VIII, and such Excess Funding Guarantor shall not exercise any right or
remedy with respect to such excess until payment and satisfaction in full of all
of such obligations. For purposes hereof, (a) "Excess Funding Guarantor" shall
mean, in respect of any obligations arising under the other provisions of this
Article VIII (hereafter, the "Guarantied Obligations"), a Guarantor that has
paid an amount in excess of its Pro Rata Share of the Guarantied Obligations;
(b) "Excess Payment" shall mean, in respect of any Guarantied Obligations, the
amount paid by an Excess Funding Guarantor in excess of its Pro Rata Share of
such Guarantied Obligations; and (c) "Pro Rata Share", for the purposes of this
Section 8.06, shall mean, for any Guarantor, the ratio (expressed as a
percentage) of (i) the amount by which the aggregate present fair saleable value
of all of its assets and Facilities exceeds the amount of all debts and
liabilities of such Guarantor (including contingent, subordinated, unmatured,
and unliquidated liabilities, but excluding the obligations of such Guarantor
hereunder) to (ii) the amount by which the aggregate present fair saleable value
of all assets and other Facilities of the Borrower and all of the Guarantors
exceeds the amount of all of the debts and liabilities (including contingent,
subordinated, unmatured, and unliquidated liabilities, but excluding the
obligations of the Borrower and the Guarantors hereunder) of the Borrower and
all of the Guarantors, all as of the Closing Date (if any Guarantor becomes a
party hereto subsequent to the Closing Date, then for the purposes of this
Section 8.06 such subsequent Guarantor shall be deemed to have been a Guarantor
as of the Closing Date and the information pertaining to, and only pertaining
to, such Guarantor as of the date such Guarantor became a Guarantor shall be
deemed true as of the Closing Date).

    (g)  Continuing Guarantee.

         The guarantee in this Article VIII is a continuing guarantee, and shall
apply to all Guaranteed Obligations whenever arising.

Item 48.

SECURITY

    (a)  Priority and Liens.

         (a)      Each of the Credit Parties hereby covenants, represents and
                  warrants that, upon entry of the Interim DIP Financing Order
                  (i) pursuant to Section 364(c)(1) of the Bankruptcy Code, the
                  Obligations shall at all times constitute allowed
                  administrative expense claims in the Bankruptcy Cases with
                  priority over all administrative expense claims and unsecured
                  claims against the Credit Parties, now existing or hereafter
                  arising, of any kind or nature whatsoever, including, without
                  limitation, administrative expenses of the kinds specified in
                  or ordered pursuant to Sections 105, 326, 330, 331, 503(a),
                  503(b), 506(c), 507(a), 507(b), 546(c), 546(d), and 1114 of
                  the Bankruptcy Code and (ii) pursuant to Sections 364(c)(2)
                  and 364(d) of the Bankruptcy Code, the Obligations shall at
                  all times be secured by a perfected first priority Lien on all
                  property and assets of each member of the Transit Group,
                  except for the Excluded Assets, and all assets directly
                  related to the Specified Contracts (other than the equipment
                  set forth on Schedule III) subject only to (A) Senior Liens,
                  (B) the Carve Out (defined below) in an aggregate amount not
                  in excess of $1,450,000 (the "Carve-Out") and (C) the
                  UST/Clerk Fees. The Carve-Out may be used only to pay the fees
                  and expenses of professionals employed by the Credit Parties,
                  the fees and expenses of professionals employed by

                                       51

                  any statutory committee appointed by the Bankruptcy Court
                  under Section 1102 of the Bankruptcy Code ("Statutory
                  Committee"), and the expenses of members of any such Statutory
                  Committee; provided that all such fees and expenses are
                  authorized to be paid or approved by the Bankruptcy Court to
                  the extent required under the Bankruptcy Code; provided,
                  however, that the Carve-Out shall not include, apply to or be
                  available for any fees or expenses incurred by any party,
                  including the Credit Parties or any Statutory Committee, in
                  connection with the initiation or prosecution (but not
                  investigation) of any claims, causes of action, adversary
                  proceedings or other litigation against the Administrative
                  Agent or the Lenders, including, without limitation,
                  challenging the amount, validity, priority or enforceability
                  of, or asserting any defense, claim, counterclaim or offset
                  to, the Obligations or the Liens of the Administrative Agent
                  and the Lenders under this Agreement in respect thereof. The
                  Lenders agree that so long as the Maturity Date shall not have
                  occurred or the Administrative Agent or the Lenders have not
                  exercised any remedies as a result of an Event of Default, the
                  Credit Parties shall be permitted to pay compensation and
                  reimbursement of expenses accrued and payable under 11
                  U.S.C.ss. 330 and 11 U.S.C.ss. 331, as the same may be due and
                  payable as authorized by the Bankruptcy Court, and the same
                  shall not reduce the amount available under the Carve-Out. The
                  foregoing shall not be construed as a consent to the allowance
                  of any fees and expenses or bonuses referred to above and
                  shall not affect the right of the Credit Parties, the
                  Administrative Agent or the Lenders to object to the allowance
                  and payment of such amounts.

         (b)      As to all real property the title to which is held by any of
                  the Credit Parties, or the possession of which is held by any
                  of the Credit Parties pursuant to a leasehold interest or
                  otherwise, each of the Credit Parties hereby assigns and
                  conveys as security, grants a security interest in,
                  hypothecates, mortgages, pledges and sets over unto the
                  Administrative Agent on behalf of the Lenders all of the
                  right, title and interest of such Credit Party in all of such
                  owned real property and in all such leasehold interests or
                  other interests, together in each case with all of the right,
                  title and interest of such Credit Party in and to all
                  buildings, improvements, and fixtures related thereto, any
                  lease or sublease thereof, all general intangibles relating
                  thereto and all proceeds thereof, such assignment, conveyance
                  and security interest to have the priorities set forth in
                  Section 9.01(a)(i) and (ii) above.

         (c)      Each of the Credit Parties acknowledges that, pursuant to the
                  DIP Financing Orders, the Liens in favor of the Administrative
                  Agent on behalf of the Lenders in all of such real property
                  and leasehold interests, and all of the other Collateral,
                  shall be perfected without the taking of any further action,
                  including any recordation of any instruments of mortgage or
                  assignment, or the recording or filing of any financing
                  statements, notices of lien or other similar instruments.

Item 49.

THE ADMINISTRATIVE AGENT

    (a)  Appointment.

         The Lenders hereby designate and appoint CSFB, as Administrative Agent
of the Lenders to act as specified herein and the other Credit Documents, and
each of the Lenders hereby authorizes the Administrative Agent to take such
action on its behalf under the provisions of this Agreement and the other Credit
Documents and to exercise such powers and perform such duties as are expressly
delegated to the Administrative Agent by the terms hereof and of the other
Credit Documents, together with such other powers as are reasonably incidental
thereto. Notwithstanding any provision to the contrary elsewhere herein and in

responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any of the other Credit Documents, or shall otherwise exist against
the Administrative Agent. The provisions of this Article X are solely for the
benefit of the Administrative Agent and the Lenders, and none of the Credit
Parties shall have any rights as a third party beneficiary of the provisions
hereof. In performing its functions and duties under this Agreement and the
other

to have assumed any obligation or relationship of agency or trust with or for
any Credit Party or any of their respective Affiliates.

    (b)  Delegation of Duties.

         The Administrative Agent may execute any of its duties hereunder or

misconduct of any agents or attorneys-in-fact selected by it with reasonable
care.

    (c)  Exculpatory Provisions.

         Neither the Administrative Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any
action lawfully taken or omitted to be taken by them or such Person under or in
connection herewith or in connection with any of the other Credit Documents
(except for its or such Person's own gross negligence or willful misconduct), or
(ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by any of the Credit Parties
contained herein or in any of the other Credit Documents or in any certificate,
report, document, financial statement or other written or oral statement
referred to or provided for in, or received by the Administrative Agent under or
in connection herewith or in connection with the other Credit Documents, or the
enforceability or sufficiency therefor of any of the other Credit Documents, or
for any failure of any Credit Party to perform its obligations hereunder or
thereunder. The Administrative Agent shall not be responsible to any Lender for
the effectiveness, genuineness, validity, enforceability, collectability or
sufficiency of this Agreement or any of the other Credit Documents or for any
representations, warranties, recitals or statements made herein or therein or
made by any Credit Party in any written or oral statement or in any financial or
other statements, instruments, reports, certificates or any other documents in
connection herewith or therewith furnished or made available by the
Administrative Agent to the Lenders or by or on behalf of the Credit Parties to
the Administrative Agent or any Lender or be required to ascertain or inquire as

or Event of Default or to inspect the properties, books or records of the Credit
Parties or any of their respective Affiliates.

    (d)  Reliance On Communications.

         The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any note, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to any of the Credit Parties, independent accountants and
other experts selected by the Administrative Agent with reasonable care). The
Administrative Agent may deem and treat the Lenders as the owners of their
respective interests hereunder for all purposes unless a written notice of
assignment, negotiation or transfer thereof shall have been filed with the
Administrative Agent in accordance with Section 11.03(b). The Administrative
Agent shall be fully justified in failing or refusing to take any action under
this Agreement or under any of the other Credit Documents unless it shall first
receive such advice or concurrence of the Majority Lenders as it deems
appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder or under any of the other Credit Documents in accordance with a
request of the Majority Lenders (or to the extent specifically provided in
Section 11.06, all the Lenders) and such request and any action taken or failure
to act pursuant thereto shall be binding upon all the Lenders (including their
successors and assigns).

    (e)  Notice of Default.

         The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless it
has received notice from a Lender or a Credit Party referring to the

                                       53
<PAGE>

Credit Document, describing such Default or Event of Default and stating that
such notice is a "notice of default." In the event that the Administrative Agent
receives such a notice, it shall give prompt notice thereof to the Lenders. The
Administrative Agent shall take such action with respect to such Default or
Event of Default as shall be reasonably directed by the Majority Lenders.

    (f)  Non-Reliance On Administrative Agent and Other Lenders.

         Each Lender expressly acknowledges that neither the Administrative
Agent nor any of its officers, directors, employees, agents, attorneys-in-fact
or affiliates has made any representations or warranties to it and that no act
by the Administrative Agent or any affiliate thereof hereinafter taken,
including any review of the affairs of any Credit Party or any of their
respective Affiliates, shall be deemed to constitute any representation or
warranty by the Administrative Agent to any Lender. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon
the Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, assets, operations, property, financial and
other conditions, prospects and creditworthiness of the Credit Parties or their
respective Affiliates and made its own decision to make its Loans hereunder and
other financial accommodations hereunder and enter into this Agreement. Each
Lender also represents that it will, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement, and to make such investigation as it deems necessary to inform
itself as to the business, assets, operations, property, financial and other
conditions, prospects and creditworthiness of the Credit Parties and their
respective Affiliates. Except for notices, reports and other documents expressly
required to be furnished to the Lenders by the Administrative Agent hereunder,
the Administrative Agent shall not have any duty or responsibility to provide
any Lender with any credit or other information concerning the business,
operations, assets, property, financial or other conditions, prospects or
creditworthiness of the Credit Parties or any of their respective Affiliates
which may come into the possession of the Administrative Agent or any of their
officers, directors, employees, agents, attorneys-in-fact or affiliates.

    (g)  Indemnification.

         The Lenders agree to indemnify the Administrative Agent in its capacity
as such (to the extent not reimbursed by the Borrower and without limiting the
obligation of the Borrower to do so), ratably according to their respective
Commitments (or if the Commitments have expired or been terminated, in
accordance with the respective principal amounts of outstanding Loans of the
Lenders), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever which may at any time (including without limitation at
any time following the final payment of all of the obligations of the Borrower
hereunder and under the other Credit Documents) be imposed on, incurred by or
asserted against the Administrative Agent in its capacity as such in any way
relating to or arising out of this Agreement or the other Credit Documents or
any documents contemplated by or referred to herein or therein or the
transactions contemplated hereby or thereby or any action taken or omitted by
the Administrative Agent under or in connection with any of the foregoing;
provided that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements the extent they are found in a final judgment
by a court of competent jurisdiction to have arisen from the Administrative
Agent's gross negligence or willful misconduct. If any indemnity furnished to
the Administrative Agent for any purpose shall, in the opinion of the
Administrative Agent, be insufficient or become impaired, the Administrative
Agent may call for additional indemnity and cease, or not commence, to do the
acts indemnified against until such additional indemnity is furnished. The
agreements in this Section 10.07 shall survive the repayment of the Loans and
other obligations under the Credit Documents and the termination of the
Commitments hereunder.

    (h)  Administrative Agent In Its Individual Capacity.

         The Administrative Agent and its affiliates may make loans to, accept
deposits from and generally engage in any kind of business with the Borrower,
its Subsidiaries or its Affiliates as though the Administrative Agent were not
the Administrative Agent hereunder. With respect to the Loans and all other
obligations of the Borrower hereunder and under the other Credit Documents, the
Administrative Agent shall have the same rights and powers

                                       54
<PAGE>

under this Agreement as any Lender and may exercise the same as though it were
not the Administrative Agent hereunder, and the terms "Lender" and "Lenders"
shall include the Administrative Agent in its individual capacity.

    (i)  Successor Administrative Agent.

         The Administrative Agent may, at any time, resign upon 20 days' written
notice to the Lenders, and may be removed, upon show of cause, by the Majority
Lenders upon 30 days' written notice to the Administrative Agent; provided that
the Administrative Agent shall not resign or be removed without the prior
written consent of the Borrower, which consent shall not be unreasonably
withheld or delayed, and any attempted resignation by or removal of the
Administrative Agent without the prior written consent of the Borrower shall be
null and void ab initio. Upon any such resignation or removal, the Majority
Lenders shall have the right to appoint a successor Administrative Agent. If no
successor Administrative Agent shall have been so appointed by the Majority
Lenders, and shall have accepted such appointment, within 30 days after the
notice of resignation or notice of removal, as appropriate, then the retiring
Administrative Agent shall select a successor Administrative Agent; provided
that such successor is a Lender hereunder or a financial institution organized
under the laws of the United States of America or of any State thereof and has a
combined capital and surplus of at least $400,000,000. Upon the acceptance of
any appointment as Administrative Agent hereunder by a successor, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent, and
the retiring Administrative Agent shall be discharged from its duties and
obligations as Administrative Agent under this Agreement and the other Credit
Documents, and the provisions of this Article X 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.

    (b)  Right of Set-Off.

         In addition to any rights now or hereafter granted under applicable law
or otherwise, and not by way of limitation of any such rights, upon the
occurrence of an Event of Default, each Lender is authorized at any time and
from time to time, without presentment, demand, protest or other notice of any
kind (all of which rights being hereby expressly waived), to set-off and to
appropriate and apply any and all deposits (general or special) and any other
indebtedness at any time held or owing by such Lender (including, without
limitation branches, agencies or Affiliates of such Lender wherever located) to
or for the credit or the account of any Credit Party against obligations and
liabilities of such Person to such Lender hereunder, under the Notes, the other
Credit Documents or otherwise, irrespective of whether such Lender shall have
made any demand hereunder and although such obligations, liabilities or claims,
or any of them, may be contingent or unmatured, and any such set-off shall be
deemed to have been made immediately upon the occurrence of an Event of Default
even though such charge is made or entered on the books of such Lender
subsequent thereto. Any Person purchasing a participation in the Loans and
Commitments hereunder pursuant to Section 11.03(d) may exercise all rights of
set-off with respect to its participation interest as fully as if such Person
were a Lender hereunder.

    (c)  Benefit of Agreement.

         (a)      Generally. This Agreement shall be binding upon and inure to
                  the benefit of and be enforceable by the respective successors
                  and assigns of the parties hereto; provided that, except as
                  expressly provided herein, none of the Credit Parties may
                  assign or transfer any of its interests without prior written
                  consent of the Lenders; provided, further, that the rights of
                  each Lender to transfer, assign or grant participations in its
                  rights and/or obligations hereunder shall be limited as set
                  forth in this Section 11.03; provided, however, that nothing
                  herein shall prevent or prohibit any Lender from (i) pledging
                  its Loans hereunder to a Federal Reserve Bank in support of
                  borrowings made by such Lender from such Federal Reserve Bank
                  or (ii) granting assignments or selling participations in such
                  Lender's Loans and/or Commitments hereunder to its parent
                  company and/or to any Affiliate or Subsidiary of such Lender.

         (b)      Assignments. Each Lender may assign all or a portion of its
                  rights and obligations hereunder (including, without
                  limitation, all or a portion of its Ratable Portion of
                  Obligations and its Commitments), pursuant to an assignment
                  agreement substantially in the form of Exhibit F, to (i) a
                  Lender, (ii) an affiliate of a Lender, (iii) any fund that
                  invests in bank loans and is managed by an investment advisor
                  to a Lender or an affiliate of such investment advisor, or
                  (iv) any other Person that (A) is a bank, financial
                  institution, commercial lender or institutional investor, (B)
                  such Person shall be reasonably acceptable to the
                  Administrative Agent, and (C) so long as no Default or Event
                  of Default has occurred and is continuing, such Person shall
                  be reasonably acceptable to the Borrower (the consent of the
                  Borrower not to be unreasonably withheld or delayed); provided
                  that (i) any such assignment (other than any assignment to (I)
                  a Lender, (II) an affiliate of a Lender and (III) any fund
                  that invests in bank loans and is managed by an investment
                  advisor to a Lender or an affiliate of such investment
                  advisor) shall be in a minimum aggregate amount of $2,000,000
                  (or, if less, the remaining amount of the Commitments being
                  assigned by such Lender); and (ii) each such assignment shall
                  be of a constant, not varying, percentage of all such Lender's
                  rights and obligations under this Agreement. Any assignment
                  hereunder shall be effective upon delivery to the
                  Administrative Agent of written notice of the assignment
                  together with a transfer fee of $3,500 payable to the
                  Administrative Agent for its own account from and after the
                  later of (i) the effective date specified in the applicable
                  assignment agreement and (ii) the date of recording of such
                  assignment in the Register pursuant to the terms of subsection
                  (c) below; provided, however, that no such fee shall be
                  payable in the case of an assignment to another Lender, an
                  affiliate of a Lender or any fund that invests in bank loans
                  and is managed by an investment advisor to a Lender or an
                  affiliate of such investment advisor; provided, further, that
                  in the case of contemporaneous assignments by a Lender to more
                  than one fund managed by the same investment advisor (which
                  funds are not then Lenders), only a single assignment fee of
                  $3,500 shall be payable for all such contemporaneous
                  assignments. The assigning Lender will give prompt notice to
                  the Administrative Agent and the Borrower of any such

                                       57
<PAGE>

                  assignment. Upon the effectiveness of any such assignment (and
                  after notice to, and (to the extent required pursuant to the
                  terms hereof), with the consent of, the Borrower as provided
                  herein), the assignee shall become a "Lender" for all purposes
                  of this Agreement and the other Credit Documents and, to the
                  extent of such assignment, the assigning Lender shall be
                  relieved of its obligations hereunder to the extent of the
                  Loans and Commitment components being assigned. The Borrower
                  agrees that upon notice of any such assignment and surrender
                  of the appropriate Note or Notes, it will promptly provide to
                  the assigning Lender and to the assignee separate promissory
                  notes in the amount of their respective interests
                  substantially in the form of the original Note (but with
                  notation thereon that it is given in substitution for and
                  replacement of the original Note or any replacement notes
                  thereof). By executing and delivering an assignment agreement
                  in accordance with this Section 11.03(b), the assigning Lender
                  thereunder and the assignee thereunder shall be deemed to
                  confirm to and agree with each other and the other parties
                  hereto as follows: (i) such assigning Lender warrants that it
                  is the legal and beneficial owner of the interest being
                  assigned thereby free and clear of any adverse claim; (ii)
                  except as set forth in clause (i) above, such assigning Lender
                  makes no representation or warranty and assumes no
                  responsibility with respect to any statements, warranties or
                  representations made in or in connection with this Agreement,
                  any of the other Credit Documents or any other instrument or
                  document furnished pursuant hereto or thereto, or the
                  execution, legality, validity, enforceability, genuineness,
                  sufficiency or value of this Agreement, any of the other
                  Credit Documents or any other instrument or document furnished
                  pursuant hereto or thereto or the financial condition of any
                  Credit Party or any of their respective Affiliates or the
                  performance or observance by any Credit Party of any of its
                  obligations under this Agreement, any of the other Credit
                  Documents or any other instrument or document furnished
                  pursuant hereto or thereto; (iii) such assignee represents and
                  warrants that it is legally authorized to enter into such
                  assignment agreement; (iv) such assignee confirms that it has
                  received a copy of this Agreement, the other Credit Documents
                  and such other documents and information as it has deemed
                  appropriate to make its own credit analysis and decision to
                  enter into such assignment agreement; (v) such assignee will
                  independently and without reliance upon the Administrative
                  Agent, such assigning Lender or any other Lender, and based on
                  such documents and information as it shall deem appropriate at
                  the time, continue to make its own credit decisions in taking
                  or not taking action under this Agreement and the other Credit
                  Documents; (vi) such assignee appoints and authorizes the
                  Administrative Agent to take such action on its behalf and to
                  exercise such powers under this Agreement or any other Credit
                  Document as are delegated to the Administrative Agent by the
                  terms hereof or thereof, together with such powers as are
                  reasonably incidental thereto; and (vii) such assignee agrees
                  that it will perform in accordance with their terms all the
                  obligations which by the terms of this Agreement and the other
                  Credit Documents are required to be performed by it as a
                  Lender.

         (c)      Maintenance of Register. The Administrative Agent shall
                  maintain at its offices a copy of each Lender assignment
                  agreement delivered to it in accordance with the terms of
                  subsection (b) above and a register for the recordation of the
                  identity of the principal amount of each Loan outstanding
                  hereunder, the names, addresses and the Commitments of the
                  Lenders pursuant to the terms hereof from time to time (the
                  "Register"). The Administrative Agent will make reasonable
                  efforts to maintain the accuracy of the Register and to
                  promptly update the Register from time to time, as necessary.
                  The entries in the Register shall be conclusive in the absence
                  of manifest error, 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. The Register
                  shall be available for inspection by the Borrower and each
                  Lender, at any reasonable time and from time to time upon
                  reasonable prior notice.

         (d)      Participations. Each Lender may sell, transfer, grant or
                  assign participations in all or a portion of such Lender's
                  rights, obligations or rights and obligations hereunder
                  (including all or a portion of its Commitments or its Loans);
                  provided that (i) such selling Lender shall remain a "Lender"
                  for all purposes under this Agreement (such selling Lender's
                  obligations under the Credit Documents remaining unchanged)
                  and the participant shall not constitute a Lender hereunder,
                  (ii) no such participant shall have, or be granted, rights to
                  approve any amendment or waiver relating to this Agreement or
                  the other Credit Documents except to the extent any such
                  amendment or waiver would

                                       58
<PAGE>

                  (A) reduce the principal of or rate of interest on or fees in
                  respect of any Loans in which the participant is participating
                  or (B) postpone the date fixed for any payment of principal
                  (including extension of the Maturity Date or the date of any
                  mandatory prepayment), interest or fees in which the
                  participant is participating, and (iii) sub-participations by
                  the participant (except to an affiliate, parent company or
                  affiliate of a parent company of the participant) shall be
                  prohibited. In the case of any such participation, the
                  participant shall not have any rights under this Agreement or
                  the other Credit Documents (the participant's rights against
                  the selling Lender in respect of such participation to be
                  those set forth in the participation agreement with such
                  Lender creating such participation) and all amounts payable by
                  the Borrower hereunder shall be determined as if such Lender
                  had not sold such participation; provided, however, that such
                  participant shall be entitled to receive additional amounts
                  under Sections 2.10, 2.11, 2.13 and 11.02 on the same basis as
                  if it were a Lender.

    (d)  No Waiver; Remedies Cumulative.

         No failure or delay on the part of the Administrative Agent or any
Lender in exercising any right, power or privilege hereunder or under any other
Credit Document and no course of dealing between the Administrative Agent or any
Lender and any of the Credit Parties shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, power or privilege hereunder
or under any other Credit Document preclude any other or further exercise
thereof or the exercise of any other right, power or privilege hereunder or
thereunder. The rights and remedies provided herein are cumulative and not
exclusive of any rights or remedies which the Administrative Agent or any Lender
would otherwise have. No notice to or demand on any Credit Party in any case
shall entitle the Borrower or any other Credit Party to any other or further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of the Administrative Agent or the Lenders to any other or further action
in any circumstances without notice or demand.

    (e)  Payment of Expenses; Indemnification.

         (a)      The Borrower agrees to: (i) pay all reasonable out-of-pocket
                  costs and expenses (A) of the Administrative Agent and the
                  Lenders in connection with the negotiation, preparation,
                  execution and delivery and administration of this Agreement
                  and the other Credit Documents and the documents and
                  instruments referred to therein (including, without
                  limitation, the reasonable fees and expenses of counsel of the
                  Administrative Agent and the Lenders) and any amendment,
                  waiver or consent relating hereto and thereto including, but
                  not limited to, any such amendments, waivers or consents
                  resulting from or related to any work-out, renegotiation or
                  restructure relating to the performance by the Credit Parties
                  under this Agreement, (B) the development, negotiation,
                  approval and consummation of the disclosure statement and the
                  plan of reorganization of any of the Credit Parties and (C) of
                  the Administrative Agent and the Lenders in connection with
                  enforcement of the Credit Documents and the documents and
                  instruments referred to therein (including, without
                  limitation, in connection with any such enforcement, the
                  reasonable fees and disbursements of counsel for the
                  Administrative Agent and each of the Lenders); (ii) permit the
                  Administrative Agent to perform inventory and accounts
                  receivable field audits at the Borrower's expense, provided
                  that unless an Event of Default shall be in existence the
                  Borrower's obligation to reimburse the Administrative Agent
                  for such field audits shall be limited to one such field audit
                  each fiscal year; and (iii) pay and hold each of the Lenders
                  harmless from and against any and all present and future stamp
                  and other similar taxes with respect to the foregoing matters
                  and save each of the Lenders harmless from and against any and
                  all liabilities with respect to or resulting from any delay or
                  omission (other than to the extent attributable to such
                  Lender) to pay such taxes.

         (b)      The Borrower shall indemnify the Administrative Agent, each
                  Lender and their respective officers, directors, employees,
                  representatives and agents (each, an "Indemnitee") from and
                  hold each of them harmless against any and all losses,
                  liabilities, claims, damages or expenses incurred by any of
                  them as a result of, or arising out of, or in any way related
                  to, or by reason of (A) any investigation, litigation or other
                  proceeding (whether or not the any Indemnitee is a party
                  thereto) related to the entering into and/or performance of
                  any Credit Document or the use of proceeds of any Loan or the
                  consummation of any other transactions contemplated in any
                  Credit Document, including, without

                                       59
<PAGE>

                  limitation, the reasonable fees and disbursements of counsel
                  incurred in connection with any such investigation, litigation
                  or other proceeding or (B) the presence or Release of any
                  Materials of Environmental Concern at, under or from any
                  Property owned, operated or leased by the Borrower or any of
                  its Subsidiaries, or the failure by the Borrower or any of its
                  Subsidiaries to comply with any Environmental Law (but
                  excluding, in the case of either of clause (A) or (B) above,
                  any such losses, liabilities, claims, damages or expenses to
                  the extent incurred by reason of gross negligence or willful
                  misconduct on the part of the Person to be indemnified).

    (f)  Amendments, Waivers and Consents.

         No amendment or waiver of any provision of this Agreement nor consent
to any departure by the Borrower therefrom shall in any event be effective
unless the same shall be in writing and signed by the Majority Lenders, and then
any such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given; provided, however, that no amendment,
waiver or consent shall, unless in writing and signed by all the Lenders do any
of the following:

         (a)      waive any of the conditions specified in Article III except as
                  otherwise provided therein;

         (b)      increase the Commitments of the Lenders or subject the Lenders
                  to any additional obligations;

         (c)      reduce the principal of, or interest on, the Loans or any fees
                  or other amounts payable hereunder;

         (d)      postpone any date fixed for any payment of principal of, or
                  interest on, the Loans or any fees or other amounts payable
                  hereunder;

         (e)      change the percentage of the Commitments or the aggregate
                  unpaid principal amount of the Loans which shall be required
                  for the Lenders or any of them to take any action hereunder;

         (f)      release any of the Collateral except as shall otherwise be
                  provided in the Collateral Documents; or

         (g)      amend this Section 11.06;

and provided, further, that no amendment, waiver or consent shall, unless in
writing and signed by the Administrative Agent in addition to the Lenders
required above to take such action, affect the rights or duties of the
Administrative Agent under this Agreement or the other Credit Documents. Any
amendment, consent, or waiver that does not comply with the provisions of this
Section 11.06 shall be void and of no effect.

         Notwithstanding the fact that the consent of all the Lenders is
required in certain circumstances as set forth above, (x) each Lender is
entitled to vote as such Lender sees fit on any bankruptcy reorganization plan
that affects the Loans, and each Lender acknowledges that the provisions of
Section 1126(c) of the Bankruptcy Code supersede the unanimous consent
provisions set forth herein and (y) the Majority Lenders may consent to allow a
Credit Party to use cash collateral in the context of a bankruptcy or insolvency
proceeding.

    (g)  Counterparts.

         This Agreement may be executed in any number of counterparts, each of
which when so executed and delivered shall be an original, but all of which
shall constitute one and the same instrument. It shall not be necessary in
making proof of this Agreement to produce or account for more than one such
counterpart.

    (h)  Headings.

         The headings of the sections and subsections hereof are provided for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Agreement.

         All indemnities set forth herein, including, without limitation, in
Section 2.10, 2.11, 2.13, 10.07 or 11.05 shall survive the execution and

and other obligations under the Credit Documents and the termination of the
Commitments hereunder, and all representations and warranties made by the Credit
Parties herein shall survive delivery of the Notes and the making of the Loans

         (a)      THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS
                  AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL
                  BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE
                  WITH THE LAWS OF THE STATE OF NEW YORK AND THE APPLICABLE

                  Document shall be brought in the Bankruptcy Court or the
                  United States District Court for the District of Maryland and,
                  by execution and delivery of this Agreement, each of the
                  parties hereto hereby irrevocably accepts for itself and in
                  respect of its property, generally and unconditionally, the
                  jurisdiction of such court. Each of the Credit Parties further
                  irrevocably consents to the service of process out of any of
                  the aforementioned courts in any such action or proceeding by

                  postage prepaid, to it at the address set out for notices
                  pursuant to Section 11.01, such service to become effective
                  three (3) days after such mailing. Nothing herein shall affect
                  the right of the Administrative Agent or any Lender to serve
                  process in any other manner permitted by law or to commence
                  legal proceedings or to otherwise proceed against any Credit
                  Party in any other jurisdiction.

         (c)      TO THE EXTENT PERMITTED BY LAW, THE ADMINISTRATIVE AGENT, THE
                  LENDERS, THE BORROWER AND THE OTHER CREDIT PARTIES HEREBY
                  IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,

                  TRANSACTIONS CONTEMPLATED HEREBY.

    (k)  Severability.

         If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable and
the remaining provisions shall remain in full force and effect and shall be
construed without giving effect to the illegal, invalid or unenforceable
provisions.

         (a)      This Agreement shall become effective at such time on or after
                  the Closing Date when it shall have been executed by the
                  Borrower, the Guarantors and the Administrative Agent, and the

the Administrative Agent and each Lender and their respective successors and
assigns.

         (b)      The term of this Agreement shall commence on the effective
                  date pursuant to subsection (a) above and shall continue until
                  no Obligations or any other amounts payable hereunder or under
                  any of the other Credit Documents shall remain outstanding and
                  until all of the Commitments hereunder shall have expired or
                  been terminated.

    (n)  Confidentiality.

         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 regulatory
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;
(e) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or the enforcement of rights
hereunder; (f) subject to an agreement containing provisions substantially the
same as those of this Section 11.14, 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 (ii) any direct or indirect contractual
counterparty or prospective counterparty (or such contractual counterparty's or
prospective counterparty's professional advisor) to any credit derivative
transaction relating to obligations of the Borrower; (g) with the consent of the
Borrower; (h) to the extent such Information (i) becomes publicly available
other than as a result of a breach of this Section 11.14 or (ii) becomes
available to the Administrative Agent or any Lender on a nonconfidential basis
from a source other than the Borrower; or (i) to the National Association of
Insurance Commissioners or any other similar organization or any nationally
recognized rating agency that requires access to information about a Lender's or
its Affiliates' investment portfolio in connection with ratings issued with
respect to such Lender or its Affiliates. For the purposes of this Section,
"Information" means all information received from the Borrower relating to the
Borrower or its business, other than any such information that is available to
the Administrative Agent or any Lender on a nonconfidential basis prior to
disclosure by the Borrower; provided that, in the case of information received
from the Borrower after the date hereof, such information is clearly identified
in writing at the time of delivery as confidential. Any Person required to
maintain the confidentiality of Information as provided in this Section 11.14
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.

    (o)  Source of Funds.

         Each of the Lenders hereby represents and warrants to the Borrower that
at least one of the following statements is an accurate representation as to the
source of funds to be used by such Lender in connection with the financing
hereunder:

         (a)      no part of such funds constitutes assets allocated to any
                  separate account maintained by such Lender in which any
                  employee benefit plan (or its related trust) has any interest;

         (b)      to the extent that any part of such funds constitutes assets
                  allocated to any separate account maintained by such Lender,
                  such Lender has disclosed to the Borrower the name of each
                  employee benefit plan whose assets in such account exceed 10%
                  of the total assets of such account as of the date of such
                  purchase (and, for purposes of this subsection (b), all
                  employee benefit plans maintained by the same employer or
                  employee organization are deemed to be a single plan);

         (c)      to the extent that any part of such funds constitutes assets
                  of an insurance company's general account, such insurance
                  company has complied with all of the requirements of the
                  regulations issued

                                       62
<PAGE>

                  under Section 401(c)(1)(A) of ERISA or such insurance company
                  meets the requirements of Department of Labor Exemption 95-60;
                  or

         (d)      such funds constitute assets of one or more specific benefit
                  plans which such Lender has identified in writing to the
                  Borrower.

         As used in this Section 11.15, the terms "employee benefit plan" and
"separate account" shall have the respective meanings assigned to such terms in
Section 3 of ERISA.

    (p)  Conflict.

         To the extent that there is a conflict or inconsistency between any
provision hereof, on the one hand, and any provision of any Credit Document, on
the other hand, this Agreement shall control. To the extent that there is a
conflict or inconsistency between any provision of any Credit Document, on the
one hand, and any provision of the DIP Financing Order, on the other hand, the
DIP Financing Order shall control.

    (q)  Limitation on Liability.

         NO CLAIM MAY BE MADE BY THE ADMINISTRATIVE AGENT, ANY CREDIT PARTY, ANY
LENDER OR OTHER PERSON AGAINST THE ADMINISTRATIVE AGENT, ANY LENDER, ANY CREDIT
PARTY OR THE AFFILIATES, DIRECTORS, OFFICERS, OFFICERS, EMPLOYEES, OR AGENTS OF
ANY OF THEM FOR ANY SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES IN

paid upon such Bond has not been reimbursed to Travelers, or (iii) the sum of
the total undrawn amount of all letters of credit held by Travelers with respect
to any Bond under this paragraph shall be an amount that is less than 40% of the
penal sum of the Bond to which such letters of credit relate then outstanding
hereunder (except as Travelers may otherwise agree), such letter of credit may
be drawn upon by Travelers (letters of credit acceptable to Travelers in its
discretion are referred to herein as "Acceptable Letters of Credit"). Any such
drawing referred to in the preceding sentence, and any other cash collateral
held by Travelers hereunder, shall be held by Travelers in an interest bearing
demand account as cash collateral for the obligations of the Indemnitors
hereunder with respect to the Bond for which the letter of credit was issued.
Any cash collateral held by Travelers (and the proceeds of any other collateral
held by Travelers) securing the obligations of the Indemnitors hereunder may be
applied to such obligations, in such order and manner as may be determined by
Travelers in its discretion, at any time after the occurrence and during the
continuance of an Event of Default.

     (c) Issuance of Bond by Travelers. Travelers may issue Bonds on behalf of
one or more of the Indemnitors, in the sole discretion of Travelers, based upon
its usual and customary bond underwriting criteria for the Borrower and other
similar companies. In the exercise of its discretion applying such criteria,
Travelers has the right to refuse to

                                       12
<PAGE>

provide any Bond, including final Bonds where Travelers provided a bid bond,
without incurring any liability whatsoever to any Indemnitor or other party.

     (d) Indemnification and Exoneration. The Borrower and each of the other
Indemnitors jointly and severally agree to exonerate, indemnify and save
Travelers harmless from and against every claim, loss, damage, demand,
liability, cost, charge, suit, judgment, reasonable attorney's fee, and other
reasonable expenses which Travelers incurs in consequence of having executed, or
procured the execution of any Bond issued pursuant to this Agreement including
without limitation all amounts that are paid by Travelers to or for the benefit
of a beneficiary of a Bond (collectively, "Claims"), except Claims incurred as a
direct consequence of Travelers' gross negligence or willful misconduct.
Expenses include the cost of procuring or attempting to procure release from
liability, or in bringing suit to enforce this Agreement against any Indemnitor.

     (e) Claim Settlement. Travelers shall have the right, in its sole
discretion, to determine for itself and any Indemnitor, whether any claim or
suit brought against Travelers or an Indemnitor upon any Bond issued pursuant to
this Agreement shall be paid, compromised, settled, defended, or appealed, and
its decision shall be binding and conclusive upon each of the Indemnitors. An
itemized statement thereof sworn to by an employee of Travelers or a copy of the
voucher of payment shall be prima facie evidence of the propriety and existence
of the Indemnitors' liability. Travelers shall be entitled to reimbursement for
any and all payments made by it under the reasonable belief it was necessary or
expedient to make such payments.

     (f) Books, Records, and Credit. The Indemnitors shall furnish, and
Travelers shall have the right to free access to all the books, records,
documents, and accounts of the Indemnitors for the purpose of examining and
copying them. Access shall be granted during regular business hours in a manner
that avoids unreasonable interference with the business operations of the
Borrower and any Indemnitor. Travelers shall have the right to have such access
to the credit records of the Indemnitors for underwriting purposes, for purposes
of collecting or satisfying any obligation or Indebtedness owed to Travelers, or
any other purposes related to this Agreement or the Bonds.

     (g) Premiums, Commissions, and Fees.

         (a)      Premiums. Indemnitors shall pay to Travelers, within 60 days
                  after the commencement of any project to which any Bond
                  relates, all premiums then due for every such Bond so issued.
                  Although such premiums are payable at the time set forth in
                  the preceding sentence, each premium is fully earned and
                  unconditionally payable as of the time that the Bond with
                  respect to which the premium is payable is issued. The initial
                  premium for each such Bond issued under this Agreement shall
                  be an amount calculated at the rate of $10.40 per $1,000 of
                  bonded contract amount. With respect to any Bond as to which
                  additional annual premiums are payable in accordance with
                  Travelers' customary practices and policies, Indemnitors shall
                  also pay to Travelers when due all such annual premiums until
                  Travelers is discharged and fully released in writing for such
                  Bond. Indemnitors shall also pay to Travelers when due all
                  premiums for any surety bond previously issued or administered
                  by Travelers prior to the Closing Date until Travelers is
                  discharged and fully released in writing for each such bond.
                  Indemnitors shall also pay to Travelers within thirty days of
                  the increase, extension or renewal of any bond, whether issued
                  pursuant to this Agreement or otherwise, all premiums and fees
                  for such increase, renewal or extension, at the rates charged
                  by Travelers at the time of such increase, renewal or
                  extension, until Travelers is discharged and fully released in
                  writing for each such Bond. Premiums paid hereunder shall not
                  be refundable except (i) in accordance with the ordinary and
                  customary practices of Travelers in connection with decreases
                  in the amount of a Bond as a result of changes in the cost of
                  the project that is the subject of the Bond, or (ii) as
                  required by applicable law.

         (b)      Commissions. Indemnitors shall be responsible for paying any
                  commission or broker's fee for the issuance of any Bond under
                  this Agreement, or any bond previously issued or administered
                  by Travelers prior to the Closing Date, and Travelers shall
                  have no obligation with respect thereto.

                                       13
<PAGE>

         (c)      Management Fee. In addition to any other premium, commission,
                  or fee payable by the Indemnitors to Travelers, the
                  Indemnitors shall pay to Travelers a nonrefundable,
                  noncreditable monthly fee of $10,000 (the "Management Fee")
                  until the earlier of (a) Travelers is discharged and fully
                  released in writing for all Bonds issued pursuant to this
                  Agreement, and (b) the effective date of any plan of
                  reorganization for the Borrower and the members of the Transit
                  Group, provided that the Management Fee shall not be payable
                  with respect to any month that commences more than 90 days
                  after the Closing Date unless the total penal sum of all Bonds
                  issued and outstanding under this Agreement shall at some time
                  during such month equal or exceed $40,000,000. The Management
                  Fee shall be paid in arrears and shall be due on the first
                  Business Day of each month.

         (d)      Payment of Fees. All fees payable hereunder shall be paid on
                  the dates due, in immediately available funds, to Travelers.
                  Fees paid hereunder shall not be refundable under any
                  circumstances.

         (e)      Interest. In the event (i) Travelers shall make any payment or
                  incur any loss on any Claim on account of any Bond issued
                  pursuant to this Agreement, for such time and to the extent
                  that such payment or loss shall remain unsatisfied by
                  Indemnitors for more than five (5) Business Days after demand,
                  or (ii) the Indemnitors shall fail to pay when due any other
                  amount payable by them to Travelers hereunder, Borrower shall
                  pay interest on the outstanding balance of any such payment or
                  loss from the date thereof until the principal amount thereof
                  shall be paid in full, at a rate per annum equal at all times
                  to the Prime Rate in effect from time to time plus 3.0% per
                  annum, payable monthly in arrears on the last day of each
                  month; provided, however, that for any such portion of such
                  payment or loss that shall remain unsatisfied for more than
                  ninety (90) days, such payment or loss shall bear interest to
                  the extent and for so long as such portion shall remain unpaid
                  beyond such ninety (90) days, payable on demand, at a rate per
                  annum equal at all times to the Prime Rate in effect from time
                  to time plus 5.0% per annum.

     (h) Reserves. To the extent (a) a reserve is required by applicable laws
and regulations, and/or (b) after taking into account any collateral posted as
security for the satisfaction of any obligation covered by a Bond issued
pursuant to this Agreement, Travelers shall post a reserve, for any loss
incurred or expected to be incurred on any Bond issued pursuant to this
Agreement, the Indemnitors jointly and severally agree to pay to Travelers on
demand an amount equal to the amount of any such reserve. A certificate as to
the amount of any such reserve and the cost of such reserve, submitted to
Borrower, shall be conclusive and binding for all purpose, absent manifest
error.

      (i) Payments and Computations.

         (a)      Indemnitors shall make each payment to be made hereunder on
                  the day when due, in Dollars, to Travelers in immediately
                  available funds without set-off or counterclaim. Payments
                  received by Travelers after 3:00 P.M. (New York City time)
                  shall be deemed to be received on the next Business Day.

         (b)      All computations of interest shall be made by Travelers on the
                  basis of a year of 365 or 366 days, as the case may be, for
                  the actual number of days (including the first day but
                  excluding the last day) occurring in the period for which such
                  interest is payable. Each determination by Travelers of an
                  interest rate hereunder shall be conclusive and binding for
                  all purposes, absent manifest error.

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

      (j) Trust Funds. All payments due, or received for or on account of any
Contract of any Indemnitor, shall be held in trust as trust funds by such
Indemnitor for the benefit and payment of all obligations for which Travelers as
beneficiary may be liable under any Bond issued by Travelers on behalf of any
Indemnitor under this Agreement or any surety bond issued or administered by
Travelers prior to the Closing Date. The Borrower shall not permit any Bonded
Receivable with respect to the Track and Products and Services Group to be used
other than to pay the

                                       14
<PAGE>

obligations bonded by Travelers for each such project, and shall segregate such
Bonded Receivable for such purpose, except as Travelers may otherwise expressly
agree and except that, after Travelers gives notice to the Borrower that
Travelers agrees that there is a Surplus with respect to a Contract, which
notice or agreement shall not be unreasonably withheld or delayed, the Borrower
may permit an amount up to the amount of such Surplus to be used for other
purposes. In the event Travelers shall take over any project as provided in
Section 7.02, any trust funds held with respect to such project shall be turned
immediately over to Travelers.

     (k) Treatment of Bonds Prior to Maturity or Upon Sale or Liquidation. On or
before the Maturity Date (or at such other time as Travelers and the Borrower
may agree), the Borrower shall cause any surety bond issued by Travelers with
respect to any member of the Transit Group or the Track and Products and
Services Group, whether issued or administered by Travelers prior to the Closing
Date or pursuant to this Agreement, to be collateralized or otherwise assured of
satisfaction or payment in an amount and manner acceptable to Travelers. On or
before the date of (i) any sale of all or substantially all of the assets of any
Person that is a member of the Consolidated Group, in one or a series of
transactions, (ii) any liquidation of the assets of any Person that is a member
of the Consolidated Group, or (iii) any sale or other transfer by the Borrower
or any other Indemnitor of any Subsidiary to a Person that is not an Indemnitor,
in one or a series of transactions, of a majority of the Voting Stock of any
Person that is a member of the Consolidated Group, the Borrower shall cause any
surety bond issued by Travelers with respect to such Person or Subsidiary,
whether issued or administered by Travelers prior to the Closing Date or
pursuant to this Agreement, to be collateralized or otherwise assured of payment
in an amount and manner acceptable to Travelers.

         (d)   Subject to the entry of the Interim DIP Financing Order, this
               Agreement constitutes a legal, valid and binding obligation of
               each Indemnitor in accordance with its terms without defense,
               setoff, or counterclaim.

     (e) No Material Litigation. Other than the Bankruptcy Cases, no claim,
litigation, investigation or proceeding of or before any arbitrator or
Governmental Authority is pending or, to the best knowledge of any Indemnitor,
threatened by or against, any members of the Consolidated Group or against any

Liens and Senior Liens.

     (h) Intellectual Property. Each of the members of the Consolidated Group
owns, or has the legal right to use, the Intellectual Property necessary for it
to conduct its business as currently conducted, except for those the failure to
own or have such legal right to use would not be reasonably expected to have a
Material Adverse Effect. No claim has been asserted and is pending by any Person
challenging or questioning the use of any such Intellectual Property or the
validity or effectiveness of any such Intellectual Property, nor does any
Indemnitor know of any such claim, and the use of such Intellectual Property by
the members of the Consolidated Group does not infringe on the rights of any
Person, except for such claims and infringements that in the aggregate, would
not be reasonably expected to have a Material Adverse Effect.

     (i) No Burdensome Restrictions. Neither the certificate of incorporation or
bylaws (or other organizational or governing documents) of, nor any Requirement
of Law applicable to the members of the Consolidated Group would be reasonably
expected to have a Material Adverse Effect.

material reports required to be filed, and has paid all Federal and other taxes,
assessments, fees and other governmental charges levied or imposed upon it or
its properties, income or assets otherwise due and payable unless such unpaid
taxes and assessments (a) arose prior to the Filing Date and are not the subject
of a pending and unstayed assessment or collection action; or (b) are (i) not
yet past due or (ii) being contested in good faith and by appropriate
proceedings diligently pursued and as to which adequate reserves determined in
accordance with GAAP have been established on such Indemnitor's books and
records and no Lien with respect to nonpayment thereof has been asserted. No
Indemnitor is aware of any proposed tax assessments against it, with respect to
any prior period, in excess of amounts accrued on its financial statements (as
required to be accrued in accordance with GAAP), nor does any Indemnitor
anticipate any further material tax liability with respect to any open taxable
years taken as a whole in excess of accrued amounts.

               could give rise to liability under Environmental Laws.

projections), nor any of the information delivered in writing to the Bankruptcy
Court by or on behalf of any member of the Consolidated Group in connection with

               Facilities (subject to applicable grace or cure periods, if any)
               as such term, covenant, obligation, or agreement exists on the
               Closing Date; or

          (e)  Guaranties. Except as to any Indemnitor which is dissolved,
               released or merged or consolidated out of existence as the result
               of or in connection with a dissolution, merger or disposition
               permitted by this Agreement, the guaranty given by any Indemnitor
               hereunder or any material provision thereof shall cease to be in
               full force and effect, or any Indemnitor or any Person acting by
               or on behalf of such Indemnitor shall deny or disaffirm a
               Subsidiary Indemnitor's obligations hereunder; or

          (f)  Judgments. Any member of the Consolidated Group shall fail within
               30 days of the date due and payable to pay, bond or otherwise
               discharge any judgment, settlement or order for the payment of
               money relating to claims arising after the Filing Date which
               judgment, settlement or order, when aggregated with all other
               such judgments, settlements or orders due and unpaid at such
               time, exceeds $500,000, and which is not stayed on appeal (or for
               which no motion for stay is pending) or is not otherwise being
               executed; or

          (g)  Ownership. There shall occur a Change of Control; or

          (h)  Reorganization Plan. Any Indemnitor shall file, or shall consent
               to, encourage, support or assist in any manner with, the filing
               by any other Person, with the Bankruptcy Court of a
               reorganization plan in respect of the Borrower or any of its
               Subsidiaries that, on or before the Maturity Date (or at such
               other time as Travelers and the Borrower may agree), does not
               provide that any surety bond issued by Travelers with respect to
               any member of the Transit Group or the Track and Products and
               Services Group, whether issued or administered by Travelers prior
               to the Closing Date or pursuant to this Agreement, shall be
               collateralized or otherwise assured of satisfaction or payment in
               an amount and manner acceptable to Travelers; or

          (i)  Bankruptcy Cases. Any of the Bankruptcy Cases shall be dismissed
               or converted to a case under Chapter 7 of the Bankruptcy Code; a
               trustee under Chapter 7 or Chapter 11 of the Bankruptcy Code
               shall be appointed in any of the Bankruptcy Cases; or any
               Indemnitor shall file or support any application for the approval
               of, or there shall arise, any other claim which is an
               administrative expense claim having priority over any or all
               administrative expenses of the kind specified in Sections 503(b)
               or 507(b) of the Bankruptcy Code; or the Bankruptcy Cases of any
               two or more members of the Consolidated Group other than
               Indemnitors in the Transit Group shall be substantively
               consolidated without Travelers prior consent; or

          (j)  Relief to Lien Holders. The Bankruptcy Court shall enter an order
               granting relief from the automatic stay applicable under section
               362 of the Bankruptcy Code permitting foreclosure on any asset of
               any Indemnitor with a net depreciated book value in excess of
               $500,000; or

          (k)  Appointment of Trustee. An order of the Bankruptcy Court shall be
               entered in any of the Bankruptcy Cases appointing a trustee or
               examiner with expanded powers (powers beyond those set forth in
               Section 1106(a)(3) and (4) of the Bankruptcy Code) to operate the
               Borrower's business or a substantial portion thereof which is not
               consented to in writing by Travelers; or

                                       30
<PAGE>

          (l)  DIP Financing Orders. An order of the Bankruptcy Court which is
               not consented to in writing by Travelers shall be entered
               amending, supplementing, staying for a period in excess of five
               (5) days, vacating or otherwise modifying (or having the effect
               of any of the foregoing with respect to) the Interim DIP
               Financing Order or the Final DIP Financing Order which is not
               consented to in writing by Travelers; or

          (m)  DIP Financing Final Order. The Final DIP Financing Order, in a
               form satisfactory to Travelers and containing the provisions
               outlined herein shall not have been entered by the Bankruptcy
               Court on or before the expiration of the Interim Period; or

          (n)  Order of Bankruptcy Court. An order shall be entered by the
               Bankruptcy Court confirming a plan of reorganization or
               liquidation in the Bankruptcy Cases which does not provide that
               any surety bond issued by Travelers with respect to any member of
               the Transit Group or the Track and Products and Services Group,
               whether issued or administered by Travelers prior to the Closing
               Date or pursuant to this Agreement, shall be collateralized or
               otherwise assured of satisfaction or payment in an amount and
               manner acceptable to Travelers on or before the effective date of
               such plan.

     (b)  Acceleration; Remedies. Upon the occurrence and during the
continuation of an Event of Default, without further order of, application to,
or action by the Bankruptcy Court, Travelers may on five days' written notice to
the Borrower terminate the issuance of any further Bonds and declare that all or
any portion of the Indemnitors' obligations under the Bonds and this Agreement
are immediately due and payable. In addition, subject solely to any requirement
of the giving of notice by the terms of the Interim DIP Financing Order or the
Final DIP Financing Order, the automatic stay provided in Section 362 of the
Bankruptcy Code shall be automatically vacated without further action or order
of the Bankruptcy Court, and Travelers shall be entitled to exercise all of its
respective rights and remedies under this Agreement and applicable law,
including without limitation, any right of exoneration. In the event the
Borrower or any Indemnitor shall abandon or default in the payment or
performance of any obligation on any Contract bonded by Travelers pursuant to a
bond issued by Travelers or administered by Travelers (other than a default
arising because the amount or validity of such obligation is currently being
contested in good faith by appropriate proceedings and reserves, if applicable,
in conformity with GAAP with respect thereto have been provided on the books of
the Consolidated Group), any receivable owing on such Contract shall be
segregated and held for the satisfaction of the defaulted or abandoned
obligation and Travelers, as the case may be. If Borrower or any member of the
Transit Group shall abandon or default in the payment or performance of any
obligation on any Contract in the Transit Group (including any Specified
Contract) bonded by Travelers pursuant to a bond issued by Travelers or
administered by Travelers (other than a default arising because the amount or
validity of such obligation is currently being contested in good faith by
appropriate proceedings and reserves, if applicable, in conformity with GAAP
with respect thereto have been provided on the books of the Consolidated Group),
Travelers, at its election, may take over such bonded Contract or obligation at
any time and complete the contract or obligation itself or with another
contractor or obligor, in which case Travelers may have the use of all job site
equipment for such purpose with the payment of a reasonable rental to be made
first to the Transit Lenders for so long as any indebtedness shall remain
outstanding under the Transit Credit Agreement and the Bond Support Credit
Agreement, thereafter to the Pre-Petition Agent for so long as any indebtedness
shall remain outstanding under the Pre-Petition Credit Agreement, and thereafter
to the Borrower. If Borrower or any member of the Track and Products and
Services Group shall abandon or default in the payment or performance of any
obligation on any Contract in the Track and Products and Services Group bonded
by Travelers pursuant to a bond issued by Travelers or administered by Travelers
(other than a default arising because the amount or validity of such obligation
is currently being contested in good faith by appropriate proceedings and
reserves, if applicable, in conformity with GAAP with respect thereto have been
provided on the books of the Consolidated Group), Travelers, at its election,
may take over such bonded Contract or obligation at any time and complete the
contract or obligation itself or with another contractor or obligor, in which
case Travelers may have the use of all job site equipment for such purpose with
the payment of a reasonable rental to be made first to the Bank Administrative
Agent for so long as any indebtedness shall remain outstanding under the TP&S
Revolving Credit Agreement, thereafter to the Pre-Petition Agent for so long as
any indebtedness shall remain outstanding under the Pre-Petition Credit
Agreement, and thereafter to the Borrower. Such reasonable rental shall be
determined (a) by agreement between Travelers and the Person to whom the rental
is initially payable or (b) if not agreed within thirty (30) days after
Travelers has commenced its use of the equipment, by order of the Bankruptcy
Court after notice and a hearing, provided that (i) Travelers shall have the

                                       31
<PAGE>

right to use the equipment with respect to a bonded Contract at all times after
it makes the election to take over such bonded Contract, regardless of whether
the rental has been determined, and (ii) Travelers shall not be responsible for
the payment of any rental with respect to any time prior to its taking over such
bonded Contract.

Item 58.

GUARANTY

     (a)  Joint and Several Guaranty. Each Indemnitor hereby guarantees to
Travelers the full and punctual payment when due, as well as the performance, of
all obligations and agreements of the Borrower hereunder and all obligations and
agreements of the other Indemnitors hereunder, including without limitation all
obligations and agreements arising from the issuance of any Bond, and including
all obligations which would become due but for the operation of the automatic
stay pursuant to Section 362 of the Bankruptcy Code and the operation of
Sections 502 and 506(b) of the Bankruptcy Code. This guaranty is an absolute,
unconditional and continuing guaranty of the full and punctual payment and
performance of all of such obligations and not of their collectibility only and
is in no way conditioned upon any requirement that Travelers first attempt to
collect any of such obligations from the Borrower or any Indemnitor or resort to
any collateral security or other means of obtaining payment. Should the Borrower
or any other Indemnitor default in the payment or performance of any of its
obligations or agreements hereunder, the obligations of each Indemnitor
hereunder with respect to such obligations and agreements in default shall
become immediately due and payable to Travelers, and performable for the benefit
of Travelers, without demand or notice of any nature, all of which are expressly
waived by each Indemnitor. Payments by the Indemnitors hereunder may be required
by Travelers on any number of occasions.

          (a)  Each of the obligations of the Indemnitors under this Agreement
               are joint and several. Travelers is authorized to settle with any
               one or more of the Indemnitors individually, and without
               reference to the others, and such settlement shall not bar or
               prejudice action against or affect the liability of the others,
               subject only to the limitation that Travelers shall be entitled
               to no more than a complete satisfaction of the obligations of the
               Indemnitors to Travelers.

          (b)  Each Indemnitor hereby further agrees that, in the case of any
               extension of time of payment or renewal of any of the obligations
               owing to Travelers hereunder, the same will be promptly paid in
               full when due in accordance with the terms of such extension or
               renewal.

          (c)  Notwithstanding any provision to the contrary contained herein,
               to the extent the obligations of an Indemnitor shall be
               adjudicated to be invalid or unenforceable for any reason
               (including, without limitation, because of any applicable state,
               provincial or Federal law relating to fraudulent conveyances or
               transfers or the granting of financial assistance) then the
               obligations of each Indemnitor hereunder shall be limited to the
               maximum amount that is permissible under applicable law (whether
               Federal, state or provincial and including, without limitation,
               the Bankruptcy Code). In such case or otherwise at the request of
               Travelers, each Indemnitor shall take such action and shall
               execute and deliver all such further documents required by
               Travelers to cause the obligations of such Indemnitor to be
               enforceable to the extent required by this Agreement.

     (b)  Obligations Unconditional. The obligations of the Indemnitors under
this Section are absolute and unconditional under any and all circumstances.
Each Indemnitor agrees that such Indemnitor shall have no right of subrogation,
indemnity, reimbursement or contribution against the Borrower or any other
Indemnitor for amounts paid under this Article VIII until such time as all of
the obligations owing to Travelers hereunder have been paid or otherwise
satisfied in full, and all of the Bonds have been released. Without limiting the
generality of the foregoing, it is agreed that, to the fullest extent permitted
by law, the occurrence of any one or more of the following shall not alter or
impair the liability of any Indemnitor hereunder which shall remain absolute and
unconditional as described above:

                                       32
<PAGE>

          (a)  at any time or from time to time, without notice to any
               Indemnitor, the time for any performance of or compliance with
               any of the obligations owed to Travelers hereunder shall be
               extended, or such performance or compliance shall be waived;

          (b)  the maturity of any of the obligations owed to Travelers
               hereunder shall be accelerated, or any such obligation or this
               Agreement shall be modified, supplemented, or amended in any
               respect, or any right arising hereunder or in connection with the
               issuance of a Bond shall be waived or any other guarantee of any
               of the Indemnitors shall be released, modified, or exchanged in
               whole or in part or otherwise dealt with, or there shall be any
               refinancing, compromise, consolidation or renewal of any such
               obligation or this Agreement;

          (c)  any of the obligations owed to Travelers hereunder shall be
               determined to be void or voidable or shall be subordinated to the
               claims of any Person;

          (d)  the failure of Travelers to assert any claim or demand or to
               enforce any right or remedy against any other Indemnitor or any
               other Person primarily or secondarily liable with respect to any
               of such obligations; (iv) the addition, substitution or release
               of any entity or other person primarily or secondarily liable for
               any Obligation;

          (e)  the impairment of any collateral securing any of such
               obligations, including without limitation the failure to perfect
               or preserve any rights which Travelers might have in such
               collateral security or the substitution, exchange, surrender,
               release, loss or destruction of any such collateral security; and

          (f)  any other act or omission which might in any manner or to any
               extent vary the risk of the Indemnitors or otherwise operate as a
               release or discharge of the Indemnitors, all of which may be done
               without notice to the Indemnitors.

To the fullest extent permitted by law, with respect to its obligations
hereunder, each Indemnitor hereby expressly waives diligence, presentment,
demand of payment, protest and all notices whatsoever, any requirement that
Travelers exhaust any right, power or remedy or proceed against any Person or
security, all defenses which may be available by virtue of any valuation, stay,
moratorium law or other similar law now or hereafter in effect, and all
suretyship defenses generally. To the fullest extent permitted by law, the
Indemnitors hereby expressly waive any and all rights or defenses arising by
reason of (A) any "one action" or "anti-deficiency" law which would otherwise
prevent Travelers from bringing any action, including any claim for a
deficiency, or exercising any other right or remedy (including any right of
set-off), against the Indemnitors before or after Travelers' commencement or
completion of any enforcement action, whether judicially, by exercise of power
of sale or otherwise, or (B) any other law which in any other way would
otherwise require any election of remedies by Travelers.

                                       33
<PAGE>

     (c)  Reinstatement. The obligations of the Indemnitors under this Article
VIII shall be automatically reinstated if and to the extent that for any reason
any payment by or on behalf of any Person in respect of any obligation owed to
Travelers hereunder is rescinded or must be otherwise restored, whether as a
result of any proceedings in bankruptcy or reorganization or otherwise, and each
Indemnitor agrees that it will indemnify Travelers on demand for all reasonable
costs and expenses (including, without limitation, reasonable fees and expenses
of counsel) incurred by Travelers in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

     (d)  Certain Additional Waivers. Each Indemnitor agrees that such
Indemnitor shall have no right of recourse to any security with respect to any
obligation owed to Travelers hereunder, except through the exercise of any right
of subrogation permitted herein.

     (e)  Continuing Guarantee. The guarantee of the Indemnitors in this Article
VIII is a continuing guarantee, and shall apply to all obligations owed to
Travelers with respect to any Bond issued hereunder whenever arising.

     (b)  Right of Set-Off. In addition to any rights now or hereafter granted
under applicable law or otherwise, and not by way of limitation of any such
rights, upon the occurrence of an Event of Default, Travelers is authorized at
any time and from time to time, without presentment, demand, protest or other
notice of any kind (all of which rights being hereby expressly waived), to
set-off and to appropriate and apply any and all deposits (general or special)
and any other indebtedness at any time held or owing by Travelers to or for the
credit or the account of any Indemnitor against obligations and liabilities of
such Person to Travelers, irrespective of whether Travelers shall have made any
demand hereunder and although such obligations, liabilities or claims, or any of
them, may be contingent or unmatured, and any such set-off shall be deemed to
have been made immediately upon the occurrence of an Event of Default even
though such charge is made or entered on the books of Travelers subsequent
thereto.

     (c)  Benefit of Agreement.

          (a)  Generally. This Agreement shall be binding upon and inure to the
               benefit of and be enforceable by the respective successors and
               assigns of the parties hereto; provided that, except as expressly
               provided herein, none of the Indemnitors may assign or transfer
               any of its interests without prior written consent of Travelers.

          (b)  Assignments. Travelers may assign participation of all or a
               portion of its rights and obligations hereunder to any other
               surety or co-surety.

     (d)  No Waiver; Remedies Cumulative. No failure or delay on the part of
Travelers in exercising any right, power or privilege hereunder and no course of
dealing between Travelers and any Indemnitor shall operate as a waiver thereof;
nor shall any single or partial exercise of any right, power or privilege
hereunder preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder. The rights and remedies provided
herein are cumulative and not exclusive of any rights or remedies which
Travelers would otherwise have. No notice to or demand on any Indemnitor in any
case shall entitle the Borrower or any Indemnitor to any other or further notice
or demand in similar or other circumstances or constitute a waiver of the rights
of Travelers to any other or further action in any circumstances without notice
or demand.

     (e)  Payment of Expenses; Indemnification.

          (a)  The Borrower agrees to: (i) pay all reasonable out-of-pocket
               costs and expenses (A) of Travelers in connection with the
               negotiation, preparation, execution and delivery, and
               administration of this Agreement, the Credit Facilities, and
               other matters related to Travelers' rights and interests with

                                       35
<PAGE>

               respect to any surety bond that it has issued or any Contract,
               including the negotiations and preparations undertaken in advance
               of the commencement of the Bankruptcy Cases (including, without
               limitation, the reasonable fees and expenses of counsel of
               Travelers) and any amendment, waiver, or consent relating hereto
               or thereto, including, but not limited to, any such amendments,

necessary in making proof of this Agreement to produce or account for more than

               property, generally and unconditionally, the nonexclusive
               jurisdiction of such courts, provided that, with respect to any

               to serve process in any other manner permitted by law or to
               commence legal proceedings or to otherwise proceed against any
               Indemnitor in any other jurisdiction.

          (c)  Each Indemnitor hereby irrevocably waives any objection which it
               may now or hereafter have to the laying of venue of any of the
               aforesaid actions or proceedings arising out of or in connection
               with this Agreement brought in the courts referred to in
               subsection (a) hereof and hereby further irrevocably waives and
               agrees not to plead or claim in any such court that any such
               action or proceeding brought in any such court has been brought
               in an inconvenient forum.

          (d)  TO THE EXTENT PERMITTED BY LAW, TRAVELERS, THE BORROWER AND THE
               OTHER INDEMNITORS HEREBY IRREVOCABLY WAIVE ALL RIGHT TO TRIAL BY
               JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR
               RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
               HEREBY.

construed without giving effect to the illegal, invalid or unenforceable
provisions.

subject matter hereof, and supersedes all prior agreements and understandings,
either oral or written, with respect to the subject matter hereof and thereof.

               the Closing Date when it shall have been executed by the

               the Borrower, the Indemnitors, Travelers and their respective
               successors and assigns.
