               substantially the form of Exhibit B, specifying therein (i) the
               date of such proposed Borrowing and (ii) the aggregate amount of
               such proposed Borrowing, accompanied by a description in
               reasonable detail of the proposed use of proceeds of such

               amount of not less than $1,000,000 or an integral multiple of
               $1,000,000 in excess thereof. Each Notice of Borrowing shall be
               irrevocable and binding on the Borrower.

          (b)  Letters of Credit. Each request for the issuance or extension of
               a Letter of Credit shall be made by delivery of a Notice of
               Request for Letter of Credit to the Issuer (with a copy to the

               time) on the third Business Day prior to the date of the
               requested issuance or extension (or such shorter period as may be
               agreed by the Issuer). Each such notice shall be irrevocable and
               shall specify, among other things, (i) that a Letter of Credit is
               requested, (ii) the date of the requested issuance or extension,
               (iii) the type, amount, expiry date and terms on which such
               Letter of Credit is to be issued or extended and (iv) the purpose
               of such Letter of Credit.

     (d)  Funding of Borrowings.

          (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 2.04, 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

                                       16
<PAGE>

               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.

     (e)  Repayment.

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

     (f)  Prepayments.

          (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 the Loans
                    outstanding and outstanding LOC Obligations shall exceed the
                    aggregate Commitments, the Borrower shall immediately prepay
                    the Loans then outstanding (and, if necessary, cash
                    collateralizing the LOC Obligations) in an amount equal to
                    such excess together accrued interest thereon.

               (b)  After payment in full of all outstanding "Obligations" (as
                    defined in the Transit Revolving Credit Agreement), the
                    Borrower shall prepay the Loans (or, if no Loans are
                    outstanding, cash collateralize the LOC Obligations) 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.

     (g)  Notes.

          The obligation of the Borrower to repay the Loans made by each Lender
and to pay the LOC Obligations to such 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, each payment made by such Lender in respect of a drawing
under a Letter of Credit 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 amount of the Loans, any amounts paid in respect of a

     (h)  Additional Provisions Relating to Letters of Credit.

          (a)  Generally. If any Letter of Credit issued hereunder shall have an
               expiry date, whether as originally issued or by extension,
               extending beyond the Maturity Date, the Borrower shall, on the
               Maturity Date, either (i) cause such Letter of Credit to be
               surrendered to the Issuer, (ii) provide to the Issuer a
               back-to-back letter of credit in respect thereof reasonably
               satisfactory to the Issuer or (iii) provide cash collateral to
               the Issuer in an amount equal to the maximum amount available to
               be drawn under such Letter of Credit. Each Letter of Credit shall
               comply with the related LOC Documents. The issuance date of each
               Letter of Credit shall be a Business Day.

          (b)  Reports. The Issuer will provide to the Administrative Agent at
               least monthly, and more frequently upon request, a detailed
               summary report on each Letter of Credit and the activity thereon,
               in form and substance acceptable to the Administrative Agent. In
               addition, the Issuer will provide to the Administrative Agent for
               dissemination to the Lenders at least quarterly, and more
               frequently upon request, a detailed summary report on each Letter
               of Credit issued by the Issuer and the activity thereon,
               including, among other things, the Credit Party for whose account
               such Letter of Credit is issued, the beneficiary, the face
               amount, the expiry date and the purpose (as provided by the
               Borrower). The Issuer will provide copies of each Letter of
               Credit to the Administrative Agent and the Lenders promptly upon
               request.

          (c)  Participation. Upon issuance of a Letter of Credit, each Lender
               shall be deemed to have purchased without recourse a risk
               participation from the Issuer in such Letter of Credit and the
               obligations arising thereunder, in each case in an amount equal
               to its Ratable Share of the obligations under such Letter of
               Credit and shall absolutely, unconditionally and irrevocably
               assume, as primary obligor and not as surety, and be obligated to
               pay to the Issuer and discharge when due, its Ratable Share of
               the obligations arising under such Letter of Credit. Without
               limiting the scope and nature of each Lender's participation in
               any Letter of Credit, to the extent that the Issuer has not been
               reimbursed as required hereunder or under any such Letter of
               Credit, each Lender shall pay to the Issuer its Ratable Share of
               such unreimbursed drawing in same day funds on the day of
               notification by the Issuer of an unreimbursed drawing pursuant to
               the provisions of subsection (d) hereof. The obligation of each
               Lender to so reimburse the Issuer shall be absolute and
               unconditional and shall not be affected by the occurrence of a
               Default, an Event of Default or any other occurrence or event.
               Any such reimbursement shall not relieve or otherwise impair the
               obligation of the Borrower to reimburse the Issuer under any
               Letter of Credit, together with interest as hereinafter provided.

          (d)  Reimbursement. In the event of any drawing under any Letter of
               Credit, the Issuer will promptly notify the Borrower. The
               Borrower promises to reimburse the Issuer on the day of drawing
               under any Letter of Credit in same day funds. If the Borrower
               shall fail to reimburse the Issuer as provided hereinabove, the
               unreimbursed amount of such drawing shall bear interest at a per
               annum rate equal to the sum of the Prime Rate plus five percent
               (5%). The Borrower's reimbursement obligations hereunder shall be
               absolute and unconditional under all circumstances irrespective
               of any rights of setoff, counterclaim or defense to payment the
               Borrower may claim or have against the Issuer, the Administrative
               Agent, the Lenders, the beneficiary of the Letter of Credit drawn
               upon or any other Person, including, without limitation, any
               defense based on any failure of the Borrower or any other Credit
               Party to receive consideration or the legality, validity,
               regularity or unenforceability of the Letter of Credit. The
               Issuer will promptly notify the Lenders of the amount of any
               unreimbursed drawing and each Lender shall promptly pay to the
               Administrative Agent for the account of the Issuer in Dollars and
               in immediately available funds, the amount of such Lender's
               Ratable Share of such unreimbursed drawing. Such payment shall be
               made on the day such notice is received by the Lenders from the
               Issuer if such notice is received at or before 2:00 P.M. (New
               York City time) otherwise such payment shall be made at or before
               12:00 Noon (New York City time) on the Business Day next
               succeeding the day such notice is received. If any Lender does
               not pay such amount to the Issuer in full upon such request, such
               Lender shall, on demand, pay to the

                                       18
<PAGE>

               Administrative Agent for the account of the Issuer interest on
               the unpaid amount during the period from the date of such drawing
               until such Lender pays such amount to the Issuer in full at a
               rate per annum equal to the Federal Funds Rate. Each Lender's
               obligation to make such payment to the Issuer, and the right of
               the Issuer to receive the same, shall be absolute and
               unconditional, shall not be affected by any circumstance
               whatsoever and without regard to the termination of this
               Agreement or the Commitments hereunder, the existence of a
               Default or Event of Default or the acceleration of the
               obligations of the Borrower hereunder and shall be made without
               any offset, abatement, withholding or reduction whatsoever.
               Simultaneously with the making of each such payment by a Lender
               to the Issuer, such Lender shall, automatically and without any
               further action on the part of the Issuer or such Lender, acquire
               a participation in an amount equal to such payment (excluding the
               portion of such payment constituting interest owing to the
               Issuer) in the related unreimbursed drawing portion of the LOC
               Obligation and in the interest thereon and in the related LOC
               Documents, and shall have a claim against the Borrower with
               respect thereto.

          (e)  Designation of other Credit Parties as Account Parties.
               Notwithstanding anything to the contrary set forth in this
               Agreement, a Letter of Credit issued hereunder may contain a
               statement to the effect that such Letter of Credit is issued for
               the account of a Guarantor, provided that, in each case
               notwithstanding such statement, the Borrower shall be the actual
               account party for all purposes of this Agreement for such Letter
               of Credit and such statement shall not affect the Borrower's
               reimbursement obligations hereunder with respect to such Letter
               of Credit.

          (f)  Renewal, Extension. The renewal or extension of any Letter of
               Credit shall, for purposes hereof, be treated in all respects the
               same as the issuance of a new Letter of Credit hereunder.

          (g)  Applicability of ISP98 and UCP. Unless otherwise expressly agreed
               by the Issuer and the Borrower when a Letter of Credit is issued,
               (i) the rules of the "International Standby Practices 1998"
               published by the Institute of International Banking Law &
               Practice (or such later version thereof as may be in effect at
               the time of issuance) shall apply to each standby Letter of
               Credit, and (ii) the rules of the Uniform Customs and Practice
               for Documentary Credits, as most recently published by the
               International Chamber of Commerce (the "ICC") at the time of
               issuance (including the ICC decision published by the Commission
               on Banking Technique and Practice on April 6, 1998 regarding the
               European single currency (euro)) shall apply to each Letter of
               Credit.

          (h)  Indemnification; Nature of Issuer's Duties.

               (a)  In addition to its other obligations under this Section
                    2.08, the Borrower hereby agrees to protect, indemnify, pay
                    and save the Issuer harmless from and against any and all
                    claims, demands, liabilities, damages, losses, costs,
                    charges and expenses (including reasonable attorneys' fees)
                    that the Issuer may incur or be subject to as a consequence,
                    direct or indirect, of (A) the issuance of any Letter of
                    Credit or (B) the failure of the Issuer to honor a drawing
                    under a Letter of Credit as a result of any act or omission,
                    whether rightful or wrongful, of any present or future de
                    jure or de facto government or governmental authority (all
                    such acts or omissions, herein called "Government Acts").

               (b)  As between the Borrower and the Issuer, the Borrower shall
                    assume all risks of the acts, omissions or misuse of any
                    Letter of Credit by the beneficiary thereof. The Issuer
                    shall not be responsible: (A) for the form, validity,
                    sufficiency, accuracy, genuineness or legal effect of any
                    document submitted by any party in connection with the
                    application for and issuance of any Letter of Credit, even
                    if it should in fact prove to be in any or all respects
                    invalid, insufficient, inaccurate, fraudulent or forged; (B)
                    for the validity or sufficiency of any instrument
                    transferring or assigning or purporting to transfer or
                    assign any Letter of Credit or the rights or benefits
                    thereunder or proceeds thereof, in whole or in part, that
                    may prove to be invalid or ineffective for any reason; (C)
                    for errors, omissions, interruptions or delays in

                                       19
<PAGE>

                    transmission or delivery of any messages, by mail, cable,
                    telegraph, telex or otherwise, whether or not they be in
                    cipher; (D) for any loss or delay in the transmission or
                    otherwise of any document required in order to make a
                    drawing under a Letter of Credit or of the proceeds thereof;
                    and (E) for any consequences arising from causes beyond the
                    control of the Issuer, including, without limitation, any
                    Government Acts. None of the above shall affect, impair, or
                    prevent the vesting of the Issuer's rights or powers
                    hereunder.

               (c)  In furtherance and extension and not in limitation of the
                    specific provisions hereinabove set forth, any action taken
                    or omitted by the Issuer, under or in connection with any
                    Letter of Credit or the related certificates, if taken or
                    omitted in good faith, shall not put the Issuer under any
                    resulting liability to the Borrower or any other Credit
                    Party. It is the intention of the parties that this
                    Agreement shall be construed and applied to protect and
                    indemnify the Issuer against any and all risks involved in
                    the issuance of the Letters of Credit, all of which risks
                    are hereby assumed by the Borrower (on behalf of itself and
                    each of the other Credit Parties), including, without
                    limitation, any and all Government Acts. The Issuer shall
                    not in any way be liable for any failure by the Issuer or
                    anyone else to pay any drawing under any Letter of Credit as
                    a result of any Government Acts or any other cause beyond
                    the control of the Issuer.

               (d)  Nothing in this subsection (h) is intended to limit the
                    reimbursement obligations of the Borrower contained in
                    subsection (d) above. The obligations of the Borrower under
                    this subsection (h) shall survive the termination of this
                    Agreement. No act or omissions of any current or prior
                    beneficiary of a Letter of Credit shall in any way affect or
                    impair the rights of the Issuer to enforce any right, power
                    or benefit under this Agreement.

               (e)  Notwithstanding anything to the contrary contained in this
                    subsection (h), the Borrower shall have no obligation to
                    indemnify the Issuer in respect of any liability incurred by
                    the Issuer (A) arising out of the gross negligence or
                    willful misconduct of the Issuer, as determined by a court
                    of competent jurisdiction, or (B) caused by the Issuer's
                    failure to pay under any Letter of Credit after presentation
                    to it of a request strictly complying with the terms and
                    conditions of such Letter of Credit, as determined by a
                    court of competent jurisdiction, unless such payment is
                    prohibited by any law, regulation, court order or decree.

          (i)  Responsibility of Issuer. It is expressly understood and agreed
               that the obligations of the Issuer hereunder to the Lenders are
               only those expressly set forth in this Agreement and that the
               Issuer shall be entitled to assume that the conditions precedent
               set forth in Article III have been satisfied unless it shall have
               acquired actual knowledge that any such condition precedent has
               not been satisfied; provided, however, that nothing set forth in
               this Section 2.08 shall be deemed to prejudice the right of any
               Lender to recover from the Issuer any amounts made available by
               such Lender to the Issuer pursuant to this Section 2.08 in the
               event that it is determined by a court of competent jurisdiction
               that the payment with respect to the relevant Letter of Credit
               constituted gross negligence or willful misconduct on the part of
               the Issuer.

          (j)  Limitation on Obligation of the Issuer. Notwithstanding anything
               contained herein to the contrary, the Issuer shall not be under
               any obligation to issue, renew or extend any Letter of Credit if
               (i) any order, judgment or decree of any Governmental Authority
               or arbitrator shall by its terms purport to enjoin or restrain
               the Issuer from issuing such Letter of Credit, or any applicable
               law, rule or regulation or any request or directive (whether or
               not having the force of law) from any Governmental Authority with
               jurisdiction over the Issuer shall prohibit, or request that the
               Issuer refrain from, the issuance of letters of credit generally
               or such Letter of Credit in particular, or shall impose upon the
               Issuer with respect to such Letter of Credit any restriction,
               reserve or capital requirement (for which the Issuer is not
               otherwise compensated hereunder) not in effect on the Closing
               Date, or shall impose upon the Issuer any unreimbursed loss,
               costs or expense which was not applicable on the Closing Date and
               which the Issuer should deem material to it in good faith, or
               (ii) the issuance, renewal or extension would violate or
               otherwise contravene its internal policy.

                                       20

          (k)  Conflict with LOC Documents. Solely as among the parties hereto,
               in the event of any conflict between this Agreement and any LOC
               Document (including any letter of credit application), this
               Agreement shall control.

     (i)  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 2.06(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.

     (j)  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)  Letter of Credit Fee. The Borrower shall pay to the
               Administrative Agent for the ratable benefit of the Lenders a fee
               (the "Letter of Credit Fee") equal to one and one-half percent
               (1.50%) per annum on the average daily maximum amount available
               to be drawn under Letters of Credit from the date of issuance to
               the date of expiration. The Letter of Credit Fee shall be payable
               quarterly in arrears on the 15th day following the last day of
               each calendar quarter for the immediately preceding calendar
               quarter (or portion thereof) beginning with the first such date
               to occur after the Closing Date (as well as on the Maturity
               Date).

          (d)  Issuer Fees. In addition to the Letter of Credit Fee, the
               Borrower agrees to pay to the Issuer Lender for its own account
               without sharing by the other Lenders (i) a fronting and
               negotiation fee of one-eighth of one percent (0.125%) per annum
               on the average daily maximum amount available to be drawn under
               Letters of Credit from the date of issuance to the date of
               expiration (the "Issuing Lender Fees") and (ii) the customary
               charges from time to time of the Issuer with respect to the
               issuance, amendment, transfer, administration, cancellation and
               conversion of, and drawings under, the Letters of Credit. The
               Issuer Fees shall be payable quarterly in arrears on the 15th day
               following the last day of each calendar quarter for the
               immediately preceding calendar quarter (or portion thereof)
               beginning with the first such date to occur after the Closing
               Date (as well as on the Maturity Date). The customary charges
               shall be payable on demand.

          (e)  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)

                                       21

               and (c), to the Persons entitled thereto. Fees paid hereunder
               shall not be refundable under any circumstances.

     (k)  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 2.11.

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

                                       22

     (m)  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
or the Issuer of agreeing to make or making, funding or maintaining any Loans or
Issuer, then the Borrower shall from time to time, within ten Business Days
after demand by such Lender or the Issuer (with a copy of such demand to the
Administrative Agent), pay to the Administrative Agent for the account of such
Lender or the Issuer additional amounts sufficient to compensate such Lender or
the Issuer 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 or the Issuer, shall be conclusive and
binding for all purposes, absent manifest error.

     (n)  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 2.12, 2.13 and
               2.15) to the Lenders, in accordance with their respective Ratable
               Portions, or the Issuer, and like funds relating to the payment
               of any other amount payable to any Lender or the Issuer to such
               Lender or the Issuer, 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 and the Issuer, if and
               to the extent payment owed to such Lender or the Issuer 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 or the Issuer 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 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.

                                       23
<PAGE>

     (o)  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 and the Issuer 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 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 or the Issuer
               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.

                                       24
<PAGE>

          (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 or the Issuer by the Administrative Agent but not the
               Borrower pursuant to subparagraph (f) of this Section.

          (p)  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 or the LOC Obligations (other than pursuant to
Section 2.12, 2.13, or 2.15) in excess of its Ratable Portion of payments on
account of the Loans or LOC Obligations obtained by all the Lenders, such Lender
shall forthwith purchase from the other Lenders such participations in their
Loans and LOC Obligations 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.

               before and after giving effect thereto, and to the application of
               the proceeds therefrom (and the acceptance by the Borrower of the
               proceeds of such Loan or issuance of such Letter of Credit shall
               constitute a representation and warranty by the Borrower that on

                    as though made on and as of such date (unless such
                    representations and warranties are made as of another date,
                    in which case they shall be true and correct as of such
                    date); and

               (b)  No Default or Event of Default has occurred and is
                    continuing or will result from the Loans being made on such
                    date.

          (b)  No Violation of Law or Injunction.

          The making of the Loans or issuance of such Letter of Credit on such

modified, amended or stayed (except to the extent that the Interim DIP Financing
Order is replaced and superseded by the Final DIP Financing Order) and shall be
in form and substance satisfactory to the Administrative Agent.

          (c)  No Order of Bankruptcy.

          No order of the Bankruptcy Court shall have been entered (i)
authorizing the Credit Parties to borrow money pursuant to section 364 of the
Bankruptcy Code from any Person (other than the Lenders pursuant to this
Agreement or otherwise) or to obtain any other credit from any Person secured by

(d) of the Bankruptcy Code, or (ii) affording any creditor adequate protection
under sections 361 through 364 of the Bankruptcy Code by granting a Lien in any
Collateral, unless the Lenders consent to such a Lien or such Lien is junior and
expressly subordinated in all respects to the Liens of the Administrative Agent
in the Collateral.

          (d)  Expiration of Interim Period.

          The obligation of the Lenders and the Issuer to extend credit under
this Agreement after the Interim Period expires shall be subject to the further

Section 3.02, the Administrative Agent shall have received evidence,
satisfactory to the Administrative Agent, that the Final DIP Financing Order has
been entered by the Bankruptcy Court and docketed by the Clerk of the Bankruptcy
Court, and that such order (i) shall be in full force and effect, (ii) shall
provide that the Credit Parties are prohibited from asserting any claims against
the Collateral pursuant to 11 U.S.C. ss.506(c) (except as provided in the Carve

               consent or authorization of, filing with, notice to or other act

               filings as are necessary in connection with the perfection of the
               Liens created by such Credit Documents).

          (d)  Subject to the entry of the DIP Financing Order, each Credit
               Document to which it is a party constitutes a legal, valid and
               binding obligation of such Credit Party enforceable against such

     (i)  Intellectual Property.

          Each Credit Party owns, or has the legal right to use, the
Intellectual Property necessary for it to conduct its business as currently
conducted, except to the extent the failure to do so 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 Credit Party know of any such claim, and the use of such
Intellectual Property by the Credit Parties does not infringe on the rights of
any Person, except for such claims and infringements that in the aggregate,

     (j)  No Burdensome Restrictions.

          Neither the Certificate of Incorporation or Bylaws (or other

due and payable unless such unpaid taxes and assessments are (a) not yet past
due or (b) 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 Credit Party's books and records and no
Lien with respect to nonpayment thereof has been asserted. No Credit Party 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 Credit Party anticipate any
further material tax liability with respect to any open taxable years taken as a
whole in excess of accrued amounts.

     (l)  ERISA.

          Except as would not reasonably be expected to have a Material Adverse
Effect:

          (a)  During the five-year period prior to the date on which this
               representation is made or deemed made: (i) no ERISA Event has
               occurred, and, to the best knowledge of the Credit Parties, no
               event or condition has occurred or exists as a result of which
               any ERISA Event could reasonably be expected to occur, with
               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, the Internal
               Revenue Code, and any other applicable federal or 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
               subject to any withdrawal liability under ERISA if any Credit
               Party or any ERISA

                                       31
<PAGE>

               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.

     (m)  Governmental Regulations, Etc.

          (a)  No part of the proceeds of the Loans hereunder will be used,
               directly or indirectly, for the purpose of purchasing or carrying
               any "margin stock" within the meaning of Regulation U. If
               requested by any Lender or the Administrative Agent, the Borrower
               will furnish to the Administrative Agent and each Lender a
               statement to the foregoing effect in conformity with the
               requirements of FR Form U-1 referred to in said Regulation U. No
               Indebtedness being reduced or retired out of the proceeds of the
               Loans hereunder was or will be incurred for the purpose of
               purchasing or carrying any margin stock within the meaning of
               Regulation U or any "margin security" within the meaning of
               Regulation T. "Margin stock" within the meanings of Regulation U
               does not constitute more than 25% of the value of the
               consolidated assets of the Borrower and its Subsidiaries. None of
               the transactions contemplated by this Agreement (including,
               without limitation, the direct or indirect use of the proceeds of
               the Loans) will violate 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.

          (b)  The Borrower will not use any proceeds of the Loans for any
               purpose that is improper under the Bankruptcy Code.

                                       32

          (n)  Appointment of Trustee. An order of the Bankruptcy Court shall be
               entered in any of the Bankruptcy Cases appointing a trustee,
               examiner or Responsible Officer 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; or

               (a)  An order of the Bankruptcy Court shall be entered amending,
                    supplementing, vacating or otherwise modifying the Interim

                    not consented to by the Administrative Agent and the
                    Lenders; or

               (b)  An order of the Bankruptcy Court shall be entered staying

                    consented to by the Administrative Agent and the Lenders (it
                    being understood that the entry of an order of the
                    Bankruptcy Court staying the Interim DIP Financing Order or
                    the Final DIP Financing Order that is not consented to by

               date of such plan.

     (b)  Acceleration; Remedies.

Lender to make any Loan and of the Issuer to issue any Letter of Credit 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, the LOC
Obligations, all interest thereon and all other amounts and Obligations payable
under this Agreement to be forthwith due and payable, whereupon the Loans, the
LOC Obligations, 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

automatically vacated without further action or order of the Bankruptcy Court,
and the Administrative Agent, the Lenders and the Issuer 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 67.

GUARANTY

     (a)  The Guarantee.

          (a)  (i) Each of the Guarantors hereby jointly and severally
               guarantees to each Lender, the Issuer 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:

                                       51
<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,
               the Issuer 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, the Issuer 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, the
Issuer 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

                                       52
<PAGE>

Guaranteed 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 68.

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

                                       53
<PAGE>

               the Credit Parties, the fees and expenses of professionals
               employed by 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, the Issuer 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, the Issuer and the Lenders under this
               Agreement in respect thereof. The Lenders and the Issuer 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, the Issuer 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 and the Issuer 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 and the Issuer 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.

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 the other Credit Documents, the

<PAGE>

solely for the benefit of the Administrative Agent, the Issuer 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 Credit Documents, the Administrative Agent
shall act solely as the Administrative Agent of the Lenders and the Issuer and
does not assume and shall not be deemed to have assumed any obligation or
relationship of agency or trust with or for any Credit Party or any of their
respective Affiliates.

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

responsible to any Lender or the Issuer 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

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, the Issuer or a Credit Party referring to the
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 and
the Issuer. 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 and the Issuer 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 and the Issuer
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 and the Issuer 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 or the Issuer by the Administrative Agent hereunder, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender or the Issuer 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 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 and the Issuer 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 or the
Issuer (including, without limitation branches, agencies or Affiliates of such
Lender or the Issuer wherever located) to or for the credit or the account of
any Credit Party against obligations and liabilities of such Person to such
Lender or the Issuer hereunder, under the Notes, the other Credit Documents or
otherwise, irrespective of whether such Lender or the Issuer 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

                                       58
<PAGE>

of Default even though such charge is made or entered on the books of such
Lender or the Issuer 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 and the Issuer; 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 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

                                       59
<PAGE>

               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 and LOC Obligation 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 (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, the
Issuer 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, the Issuer 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, the Issuer 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, the Issuer or the Lenders to any other or further action in any
circumstances without notice or demand.

     (e)  Payment of Expenses; Indemnification.

               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, the Issuer 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

               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, the Issuer 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, the
               Issuer, 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 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 limitation, the reasonable fees and

               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

                                       61

               otherwise provided therein;

          (b)  increase the Commitments of the Lenders or subject the Lenders to

               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

          (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
               Administrative Agent shall have received copies hereof (telefaxed
               or otherwise) which, when taken together, bear the signatures of
               each Lender and the Issuer, and thereafter this Agreement shall

               Guarantors, the Administrative Agent, the Issuer and each Lender
               and their respective successors and assigns.

          (b)  The term of this Agreement shall commence on the effective date

               Documents shall remain outstanding and until all of the
               Commitments hereunder shall have expired or been terminated.

     (n)  Confidentiality.

          The Administrative Agent, the Issuer 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 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,
the Issuer or any Lender on a nonconfidential basis prior to disclosure by the

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

                                       64
<PAGE>

               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 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, THE ISSUER OR OTHER PERSON AGAINST THE ADMINISTRATIVE AGENT, ANY
LENDER, THE ISSUER, 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 RESPECT OF ANY CLAIM FOR BREACH OF CONTRACT
OR ANY OTHER THEORY OF LIABILITY ARISING OUT OF OR RELATED TO THE TRANSACTIONS
CONTEMPLATED BY THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT, OR ANY ACT,
OMISSION OR EVENT OCCURRING IN CONNECTION THEREWITH, AND THE CREDIT PARTIES, THE
ADMINISTRATIVE AGENT, THE ISSUER AND EACH LENDER HEREBY WAIVE, RELEASE AND AGREE
NOT TO SUE UPON ANY CLAIM FOR SUCH DAMAGES, WHETHER OR NOT ACCRUED AND WHETHER
OR NOT KNOWN OR SUSPECTED TO EXIST IN ITS FAVOR.
