any other person designated in writing to the Agent by a Responsible Officer as
a person entitled to give telephonic notices under this Agreement on behalf of
the Borrowers. In each such case, each Borrower hereby waives the right to
dispute the Agent's record of the terms of any such telephonic notice.

          (b)     DISBURSEMENT OF FUNDS. No later than 2:00 p.m. (prevailing New
York Time) on the date of each such Revolving Credit Loan, each Lender will make
available its Pro Rata Share of such Revolving Credit Loan requested to be made
on such date in immediately available funds to the Agent at its Payment Office
and the Agent shall make such funds available to the applicable Borrower by
depositing such funds into such Borrower's account at the Agent's

                                       14
<Page>

Payment Office. Unless the Agent shall have been notified by any Lender prior to
the date of any such Revolving Credit Loan that such Lender does not intend to
make available to the Agent its Pro Rata Share of such Revolving Credit Loan,
the Agent may assume that such Lender has made such amount available to the
Agent on the date of such Revolving Credit Loan and the Agent, in reliance upon
such assumption, may (in its sole discretion and without any obligation to do
so) make available to the applicable Borrower such Pro Rata Share of such
Revolving Credit Loan. If such Pro Rata Share is not in fact made available to
the Agent by such Lender and the Agent has made available the same to the
applicable Borrower, the Agent shall be entitled to recover such amount from
such Lender. If such Lender does not pay such amount forthwith upon the Agent's
demand therefor, the Agent shall promptly notify the Borrowers, and the
Borrowers shall immediately pay such amount to the Agent. The Agent shall also
be entitled to recover from such Lender or the Borrowers, as the case may be,
interest on such amount in respect of each day from the date such amount was
made available by the Agent to the applicable Borrower to the date such amount
is recovered by the Agent, at a rate PER ANNUM equal to (x) if paid by such
Lender, the Federal Funds Rate or (y) if paid by the Borrowers, the then
applicable rate of interest for the applicable Revolving Credit Loans. Nothing
in this Section 2.03(b) shall be deemed to relieve any Lender from its
obligation to fulfill its Commitment hereunder or to prejudice any rights which
any Borrower may have against any Lender as a result of any default by such
Lender hereunder.

          (c)     MINIMUM ADVANCE AND TYPE LIMITATION. Each Revolving Credit
Loan requested hereunder shall be in an amount equal to $500,000 or any whole
multiple thereof in the case of a Base Rate Loan and $1,000,000 or any whole
multiple thereof in the case of a LIBOR Loan, EXCEPT that any Revolving Credit
Loan may be in the aggregate amount of the Availability. At no single time
during the Revolving Credit Period shall there be any more than six (6) LIBOR
Loans outstanding under the Revolving Credit Facility.

          2.04    REDUCTION OF COMMITMENT. The Borrower shall have the right,
upon not less than three (3) Business Days' prior written notice to the Agent
(which the Agent shall promptly transmit to the Lenders), to reduce all or part
of the Maximum Available Revolving Credit Amount, such reduction to be permanent
and irrevocable upon delivery of said notice. Any partial reduction of the
Maximum Available Revolving Credit Amount shall be in a minimum amount equal to
$500,000 or any whole multiple thereof and shall reduce each Lender's Credit
Commitment proportionately in accordance with its Pro Rata Share. Such reduction
shall not constitute an amendment hereof subject to an amendment fee set forth
in Section 3.05 hereof.

          2.05    SWINGLINE LOANS. Subject to the terms and conditions set forth
herein, the Swingline Lender agrees to make available to the Borrowers a
swingline facility (the "SWINGLINE FACILITY") pursuant to which the Swingline
Lender shall make advances (each a "SWINGLINE LOAN") to any Borrower from time
to time on any Business Day for the period commencing on the Closing Date and
expiring on the sixth (6th) Business Day preceding the Revolving Credit
Expiration Date, in an aggregate principal amount at any time outstanding that
will not result in (i) the Swingline Obligations exceeding the Swingline
Commitment or (ii) the sum of the total Revolving Credit Obligations PLUS the
aggregate principal amount of outstanding Swingline Loans exceeding the Maximum
Available Revolving Credit Amount; PROVIDED that the

                                       15
<Page>

Swingline Lender shall not be required to make a Swingline Loan to refinance an
outstanding Swingline Loan. Each Swing Loan shall be a LIBOR Market Index Rate
Loan and shall be due and payable on the maturity thereof, which shall be no
later than the seventh (7th) Business Day following the funding date of such
Loan. The Swingline Loans outstanding hereunder shall be evidenced by a
Swingline Note issued to the Swingline Lender, substantially in the form of
EXHIBIT B hereto (the "SWINGLINE NOTE"), with blanks appropriately completed in
conformity herewith. Subject to the term of this Section 2.05, Swingline Loans
may be borrowed, repaid and reborrowed by the Borrowers from time to time
without premium or penalty, and shall not be subject to Funding Losses.

          2.06.   PROCEDURES FOR SWINGLINE LOANS.

     (a)  To request a Swingline Loan, the Borrowers shall notify the Agent and
the Swingline Lender by telephone (confirmed by telecopy) no later than 11:00
a.m. (New York City Time) on the day of the relevant Swingline Loan. Each such
notice shall be irrevocable and shall specify (i) the aggregate principal amount
to be borrowed, (ii) the requested date (which shall be a Business Day) and
(iii) the maturity date of the requested Swingline Loan (which shall be not
later than seven (7) Business Days subsequent to the funding of such Swingline
Loan). The Swingline Lender will make the requested amount available promptly on
that same day by means of a credit to such Borrower's account at the Agent's
Payment Office.

     (b)  The Swingline Lender may by written notice given to the Agent not
later than 10:00 a.m. (New York Time) on any Business Day require the Lenders to
acquire participations on such Business Day in all or a portion of the Swingline
Loans then outstanding. Such notice shall specify the aggregate amount of
Swingline Loans in which the Lenders will participate. Promptly upon receipt of
such notice, the Agent will give notice thereof to each Lender, specifying in
such notice such Lender's Pro Rata Share of such Swingline Loan or Swingline
Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of
notice as provided above, to pay to the Agent, for the account of the Swingline
Lender, such Lender's Pro Rata Share of such Swingline Loan or Swingline Loans.
Each Lender acknowledges and agrees that its obligation to acquire
participations in Swingline Loans pursuant to this paragraph is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including the occurrence and continuance of a Default or Event of Default or
reduction or termination of the Commitments, and that each such payment shall be
made without any offset, abatement, withholding or reduction whatsoever. Each
Lender shall comply with its obligation under this paragraph by wire transfer of
immediately available funds, in the same manner as provided in Section 2.03(b)
hereof with respect to Revolving Credit Loans made by such Lender (and Section
2.03(b) hereof shall apply, MUTATIS MUTANDIS, to the payment obligations of the
Lenders), and the Agent shall promptly pay to the Swingline Lender the amounts
so received by it from the Lenders. The Agent shall notify the Borrowers of any
participations in any Swingline Loan acquired pursuant to this paragraph, and
thereafter payments in respect of such Swingline Loan shall be made to the Agent
and not to the Swingline Lender. Any amounts received by the Swingline Lender
from any Borrower (or other party on behalf of the Borrower) in respect of a
Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale
of participations therein shall be promptly remitted to the Agent; any such
amounts received by the Agent shall be promptly remitted by the Agent to the
Lenders that shall have made their payments pursuant to this paragraph and to
the Swingline Lender, as their interests may appear.

                                       16
<Page>

The purchase of participations in a Swingline Loan pursuant to this paragraph
shall not relieve any Borrower of any default in the payment thereof.

          2.07    INTEREST.

          (a)     INTEREST RATES. Prior to an Event of Default (i) each LIBOR
Loan shall bear interest for each day during each Interest Period applicable
thereto at a PER ANNUM rate equal to the LIBOR Rate PLUS the Applicable Margin
in effect from time to time, (ii) each Base Rate Loan shall bear interest at a
PER ANNUM rate equal to the Base Rate PLUS or MINUS (as applicable) the
Applicable Margin in effect from time to time and (iii) each LIBOR Market Index
Rate Loan shall bear interest at a PER ANNUM rate equal to the LIBOR Market
Index Rate PLUS 170 basis points (1.70%). Notwithstanding any other term or
provision hereof, upon and following an Event of Default, each Loan shall bear
interest at a PER ANNUM rate equal to rate of interest then applicable to such
Loan PLUS 200 basis points (2.00%); PROVIDED, HOWEVER, that in no event shall
such rate exceed the highest rate of interest allowed by law. Each such rate is
hereinafter referred to as the "DEFAULT RATE".

          (b)     INTEREST ACCRUAL AND PAYMENT DATE. Interest on each Loan shall
accrue from and including the date of the advance of funds with respect to such
Loan or the first day of the relevant Interest Period to but excluding the date
of repayment thereof or the expiration of the Interest Period and shall be
payable in arrears (i) in the case of a Base Rate Loan, on the last day of each
calendar month, (ii) in the case of a LIBOR Loan on the last day of the Interest
Period with respect thereto and, with respect to any LIBOR Loan with an Interest
Period in excess of three (3) months, on the date that is three (3) months after
the incurrence thereof or conversion thereto, and (iii) in the case of a
Swingline Loan, on the maturity date of such Loan as specified in Section 2.05
hereof.

          (c)     AGENT'S DETERMINATION. The Agent shall determine each interest
rate applicable to the Loans hereunder. The Agent shall give prompt written
notice to the Borrowers and the Lenders of each rate of interest so determined
and, in respect of the Base Rate, and the Applicable Margins, any change or
adjustment thereof; PROVIDED, HOWEVER that the failure of the Agent to give such
notice shall in no way affect the validity or applicability of any such
determination, change or adjustment. The Agent's determinations under this
Section 2.07(c) shall be conclusive and binding, absent manifest error.

          2.08    CONVERSIONS AND CONTINUATIONS.

          (a)     CONVERSIONS. Subject to Sections 2.03(c) and 2.05 hereof, the
Borrowers may elect from time to time to convert any Revolving Credit Loan to
any other Type of Loan by delivering to the Agent an irrevocable notice (or by
providing telephonic notice promptly confirmed in writing) of such election (A)
in the case of a conversion to a Base Rate Loan, at least one (1) Business Day
prior to the expiration of the then current Interest Period with respect to the
LIBOR Loan to be converted or (B) in the case of a conversion to a LIBOR Loan,
at least two (2) LIBOR Business Days prior to the proposed commencement of the
Interest Period of the LIBOR Loans as so converted. Any notice delivered
pursuant to this Section 2.08(a) with respect to a conversion to a LIBOR Loan
shall also specify the desired Interest Period for the

                                       17
<Page>

Loan as so converted. No Loan may be converted pursuant to this Section 2.08 (a)
(i) at any time during which an Event of Default has occurred and is continuing,
or (ii) if, after giving effect to such conversion, Section 2.03(c) hereof would
be violated. In no event shall the Borrowers be permitted to convert any Loan to
a LIBOR Loan with an Interest Period that would expire after the Revolving
Credit Expiration Date. The Agent shall give each Lender notice as promptly as
practicable of any such proposed conversion affecting any of its Loans.

          (b)     CONTINUANCE OF LIBOR LOAN. The Borrowers may elect to continue
any LIBOR Loan as such upon the expiration of the then current Interest Period
with respect thereto by delivering to the Agent an irrevocable notice (or by
providing telephonic notice thereof, promptly confirmed in writing) of such
election, at least two (2) LIBOR Business Days prior to the expiration of the
then current Interest Period with respect thereto. Such notice shall also
specify the desired Interest Period for the Loan so continued. No continuance
shall be permitted under this Section 2.08(b) at any time during which an Event
of Default has occurred and is continuing. In no event shall the Borrower be
permitted to continue any LIBOR Loan if such continuance would result in an
Interest Period with respect to such Loan expiring after the Revolving Credit
Maturity Date. The Agent shall give each Lender notice as promptly as
practicable of any such proposed continuance affecting any of its Loans.

          (c)     AUTOMATIC CONVERSION TO PRIME RATE. If the Borrowers fail to
notify the Agent of the conversion or continuance of any LIBOR Loan within the
time specified in this Section 2.08, or is otherwise not permitted to convert to
or continue any LIBOR Loan pursuant to said Section, then any such Loan shall
automatically convert to a Base Rate Loan on the last day of the then expiring
applicable Interest Period.

          2.09    LETTERS OF CREDIT.

          (a)     ISSUANCE OF LETTERS OF CREDIT. Subject to and upon the terms
herein set forth and in reliance upon the representations and warranties herein
set forth and in the other Credit Documents, the Borrower at any time and from
time to time on or after the Closing Date and prior to the Revolving Credit
Expiration Date, may request that the Agent issue, for the account of the
Borrower and in support of any Permitted L/C Obligation, an irrevocable standby
letter of credit or letters of credit in such form as may be approved by the
Agent (the "LETTER OF CREDIT FACILITY"). Notwithstanding the foregoing (i) no
Letter of Credit shall be issued in a Stated Amount which (x) when added to the
Letter of Credit Outstandings at such time would exceed the Letter of Credit
Sublimit, or (y) when added to the sum of the aggregate principal amount of the
Obligations then outstanding would exceed the Availability; (ii) each Letter of
Credit shall, unless otherwise agreed to by the Agent and the Required Lenders,
have an expiration date occurring no later than one (1) year after the date of
issuance thereof, and in no event occurring later than the Business Day next
preceding the Revolving Credit Expiration Date; (iii) each Letter of Credit
shall be denominated in U.S. dollars; and (iv) no Letter of Credit shall be
issued by the Agent after it has received a notice in writing from the Required
Lenders or the Borrower that one or more of the conditions specified in Section
5.02 hereof are not then satisfied.

                                       18
<Page>

          (b)     EXISTING LETTER OF CREDIT. ANNEX II hereto contains a
description of all letters of credit issued pursuant to the Existing Credit
Agreement and outstanding on the Closing Date. Each such letter of credit,
including any extension or renewal thereof (each, as amended from time to time
in accordance with the terms thereof, an "EXISTING LETTER OF CREDIT") shall
constitute a "LETTER OF CREDIT" for purposes of calculating the Availability
generally and the availability under the Letter of Credit Sublimit set forth
hereunder. The Borrowers shall not permit to occur any extensions or renewals of
any Existing Letters of Credit without the prior written consent of the Agent
and the Lenders. Furthermore, the Borrowers shall endeavor in good faith to
cause each Existing Letter of credit to be returned by the beneficiaries
thereunder for cancellation as soon as practicable, and cause a Letter of Credit
to be issued hereunder as a replacement for such Existing Letter of Credit.

          (c)     APPLICABILITY OF ISP98. Unless otherwise expressly agreed by
the Agent and the applicable Borrower when a Letter of Credit is issued, (i) the
rules of the "INTERNATIONAL STANDBY PRACTICES 1998" published by the Institute
of International Bank Law & Practice (or such later version thereof as may be in
effect at the time of issuance) shall apply to each Letter of Credit.

          2.10    LETTER OF CREDIT REQUESTS. Whenever a Borrower desires that a
Letter of Credit be issued for its account, it shall give the Agent at least
five (5) Business Days' notice (or such lesser number of days as may be agreed
to by the Agent and the Required Lenders). Each notice shall be executed by a
Borrower and shall be in the form of EXHIBIT D hereto (each a "LETTER OF CREDIT
REQUEST"). The Agent shall promptly transmit copies of each Letter of Credit
Request to each Lender. Each Letter of Credit Request shall be accompanied by a
completed and executed "LETTER OF CREDIT APPLICATION" (or an amendment to any
then effective application) in the form furnished by the Agent to the Borrowers
from time to time. The terms of each such application are incorporated herein to
the extent not inconsistent herewith.

          2.11    LETTER OF CREDIT PARTICIPATIONS.

          (a)     PARTICIPATIONS. Immediately upon the issuance by the Agent of
any Letter of Credit, the Agent shall be deemed to have sold and transferred to
each other Lender (each such other Lender, in such capacity under this Section
2.11, a "L/C PARTICIPANT"), and each such L/C Participant shall be deemed
irrevocably and unconditionally to have purchased and received from the Agent,
without recourse or warranty, an undivided interest and risk and income
participation (each a "L/C PARTICIPATION"), to the extent of such L/C
Participant's Pro Rata Share, in such Letter of Credit, each substitute letter
of credit, each drawing made thereunder and the obligations of the Borrower
under this Agreement with respect thereto, and any security thereof or guaranty
pertaining thereto (although the L/C Participants shall have no right to receive
any portion of any Letter of Credit Processing Fees). Upon any change in the
Commitments of the Lenders pursuant to Section 11.08 hereof, it is hereby agreed
that, with respect to all outstanding Letters of Credit and Unpaid Drawings,
there shall be an automatic adjustment to the L/C Participations pursuant to
this Section 2.11 to reflect the new Pro Rata Shares of the assignor and
assignee Lender.

                                       19
<Page>

          (b)     AGENT'S OBLIGATIONS. In determining whether to pay under any
Letter of Credit, the Agent shall have no obligation relative to the L/C
Participants or the Borrower other than to confirm that any documents required
to be delivered under such Letter of Credit have been delivered and that they
appear to comply on their face with the requirements of such Letter of Credit.
Any action taken or omitted to be taken by the Agent under or in connection with
any Letter of Credit issued by it, if taken or omitted in the absence of gross
negligence or willful misconduct, shall not create for the Agent any resulting
liability.

          (c)     PAYMENTS UPON DRAWING. In the event that the Agent makes any
payment under any Letter of Credit issued by it and the Borrowers shall not have
reimbursed such amount in full to the Agent pursuant to Section 2.10(a), the
Agent shall promptly notify each L/C Participant of such failure, and each L/C
Participant shall promptly and unconditionally pay to the Agent the amount of
such L/C Participant's Pro Rata Share of such unreimbursed payment in
immediately available funds. If the Agent so notifies, prior to 11:00 a.m.
(prevailing New York Time) on any Business Day, any L/C Participant required to
fund a payment under a Letter of Credit, shall make available to the Agent such
L/C Participant's Pro Rata Share of the amount of such payment on such Business
Day in same day funds. If and to the extent such L/C Participant shall not have
so made its Pro Rata Share of the amount of such payment available to the Agent,
such L/C Participant agrees to pay to the Agent, forthwith on demand, such
amount, together with interest thereon for each day from such date until the
date such amount is paid to the Agent at the Federal Funds Rate. The failure of
any L/C Participant to make available to the Agent its Pro Rata Share of any
payment under any Letter of Credit shall not relieve any other L/C Participant
of its obligation hereunder to make available to the Agent its Pro Rata Share of
any payment under any Letter of Credit on the date required, as specified above,
but no L/C Participant shall be responsible for the failure of any other L/C
Participant to make available to the Agent such other L/C Participant's Pro Rata
Share of any such payment.

          (d)     L/C PARTICIPANTS' DUTIES ABSOLUTE. The obligations of the L/C
Participants to make payments to the Agent with respect to Letters of Credit
shall be irrevocable and not subject to counterclaim, set-off or other defense
or any other qualification or exception whatsoever and shall be made in
accordance with the terms and conditions of this Agreement under all
circumstances, including, without limitation, any of the following
circumstances:

          (i)     any lack of validity or enforceability of this Agreement or
                  any of the other Credit Documents;

          (ii)    the existence of any claim, set-off, defense or other right
                  which a Borrower may have at any time against a beneficiary
                  named in a Letter of Credit, any transferee of any Letter of
                  Credit (or any Person for whom any such transferee may be
                  acting), the Agent, any Lender, or other Person, whether in
                  connection with this Agreement, any Letter of Credit, the
                  transactions contemplated herein or any unrelated transactions
                  (including any underlying transaction between the Borrower and
                  the beneficiary named in any such Letter of Credit);

                                       20
<Page>

          (iii)   any draft, certificate or any other document presented under
                  the Letter of Credit proving to be forged, fraudulent, invalid
                  or insufficient in any respect or any statement therein being
                  untrue or inaccurate in any respect;

          (iv)    the surrender or impairment of any security for the
                  performance or observance of any of the terms of any of the
                  Credit Documents;

          (v)     the occurrence of any Default or Event of Default; or

          (vi)    the failure of any condition precedent set forth in Section
                  5.02 hereof to have been satisfied at the time of the issuance
                  of any Letter of Credit unless the Agent shall have received a
                  notice in writing to such effect from such Lender hereof prior
                  to the issuance of such Letter of Credit.

          2.12    AGREEMENT TO REPAY LETTER OF CREDIT DRAWINGS.

          (a)     BORROWER'S OBLIGATION TO PAY DRAWINGS. The Borrowers hereby
agree to reimburse the Agent, by making payment to the Agent in immediately
available funds, for any payment or disbursement made by the Agent under any
Letter of Credit issued by it (each such amount so paid until reimbursed, an
"UNPAID DRAWING") immediately after, and in any event on the date of, notice
given by the Agent to the Borrowers of such payment (which notice the Agent
hereby agrees to give promptly after the making of any payment or disbursement
under a Letter of Credit), with interest on the amount so paid or disbursed by
the Agent, to the extent not reimbursed prior to 1:00 p.m. (prevailing New York
Time) on the date of such payment or disbursement, from and including the date
paid or disbursed to but excluding the date the Agent is reimbursed therefor, at
a rate per annum which shall be the Prime Rate as in effect from time to time
(plus an additional 200 basis points (2.00%) PER ANNUM, if not reimbursed by the
second (2nd) Business Day following any such notice of payment or disbursement),
such interest to be payable on demand.

          (b)     BORROWER'S OBLIGATIONS ABSOLUTE. The joint and several
obligations of the Borrowers under this Section 2.12 to reimburse the Agent with
respect to Unpaid Drawings (including, in each case, interest thereon) issued by
it shall be absolute and unconditional under any and all circumstances and
irrespective of any set-off, counterclaim or defense to payment which any
Borrower or any other Person may have or have had against the Agent or any
Lender, including, without limitation, any defense based upon the failure of any
drawing under a Letter of Credit (each a "DRAWING") to conform to the terms of
the Letter of Credit or any non-application or misapplication by the beneficiary
of the proceeds of such Drawing; PROVIDED, that no Borrower shall be obligated
to reimburse the Agent for any wrongful payment made by the Agent under a Letter
of Credit as a result of acts or omissions constituting willful misconduct or
gross negligence on the part of the Agent.

          2.13    INDEMNIFICATION; NATURE OF AGENT'S DUTIES.

          (a)     INDEMNIFICATION GENERALLY. Each Borrower hereby agrees to
protect, indemnify, pay and save the Agent harmless from and against any and all
claims, demands,

                                       21
<Page>

liabilities, damages, losses, costs, charges and expenses (including reasonable
attorneys' fees) that the Agent may incur or be subject to as a consequence,
direct or indirect, of (i) the issuance of any Letter of Credit or (ii) the
failure of the Agent 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 actions or
omissions, herein called "GOVERNMENT ACTS").

          (b)     ALLOCATION OF RISK. As between each Borrower and the Agent,
each Borrower shall assume all risks of the acts, omissions or misuse of any
Letter of Credit by the beneficiary thereof. The Agent shall not be responsible:
(i) 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;
(ii) 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; (iii) for failure of the beneficiary
of a Letter of Credit to comply fully with conditions required in order to draw
upon a Letter of Credit; (iv) for errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable, telegraph, telex or
otherwise; (v) for errors in interpretation of technical terms; (vi) 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 (vii)
for any consequences arising from causes beyond the control of the Agent,
including, without limitation, any Government Acts. None of the above shall
affect, impair, or prevent the vesting of any of the Agent's rights or powers
hereunder.

          (c)     SCOPE OF AGENT'S DUTIES. In furtherance and extension and not
in limitation of the specific provisions hereinabove set forth, any action taken
or omitted by the Agent under or in connection with any Letter of Credit or the
related drawing certificates, if taken or omitted in good faith, shall not put
the Agent under any resulting liability to any Borrower. The Agent shall not, in
any way, be liable for any failure by it 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 Agent.

          (d)     NO LIMITATION AS TO REIMBURSEMENT. Nothing in this Section
2.13 is intended to limit the reimbursement obligation of the Borrowers
contained in Section 2.12 hereof. The obligations of the Borrowers under this
Section 2.13 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 Agent to enforce any right, power or
benefit under this Agreement.

          (e)     LIMITATION OF INDEMNIFICATION. Notwithstanding anything to the
contrary contained in this Section 2.13, (i) no Borrower shall have any
obligation to indemnify the Agent in respect of any liability incurred by the
Agent arising solely out of the gross negligence or willful misconduct of the
Agent, as determined by a court of competent jurisdiction and (ii) the Borrowers
shall have a claim against the Agent and the Agent shall be liable to the
Borrowers to the extent, but only to the extent, of any direct, as opposed to
consequential, damages suffered by

                                       22
<Page>

the Borrowers which the Borrowers prove were caused by (x) the Agent's willful
misconduct or gross negligence in determining whether the documents presented
under a Letter of Credit complied with the terms of such Letter of Credit or (y)
the Agent's willful or grossly negligent failure to pay under a Letter of Credit
after presentation to it of a drawing certificate and any other documents
strictly complying with the terms and conditions of such Letter of Credit.

          2.14    INCREASED COSTS; ILLEGALITY; CAPITAL ADEQUACY; FUNDING LOSSES.

          (a)     INCREASED COSTS AND ILLEGALITY. In the event that (x) in the
case of clause (i) below, the Agent, and (y) in the case of clauses (ii) and
(iii) below, any Lender, shall have determined (which determination in either
case shall, absent manifest error, be final and conclusive and binding upon all
parties hereto):

                  (i)    on any date for determining the LIBOR Market Index Rate
                         or the LIBOR Rate for any Interest Period that, by
                         reason of any changes arising on or after the date of
                         this Agreement affecting the relevant capital market,
                         (x) adequate and fair means do not exist for
                         ascertaining the applicable interest rate on the basis
                         provided for in the definition of LIBOR Market Index
                         Rate or the LIBOR Rate or (y) such means will not
                         adequately and fairly reflect the cost to the Lenders
                         of funding LIBOR Loans for the relevant Interest
                         Periods; or

                  (ii)   at any time, that such Lender shall incur increased
                         costs or reductions in the amounts received or
                         receivable hereunder with respect to any LIBOR Loans
                         because of (x) any change since the date of this
                         Agreement in any applicable law, governmental rule,
                         regulation, guideline or order (or in the
                         interpretation or administration thereof and including
                         the introduction of any new law or governmental rule,
                         regulation, guideline or order) (such as, for example,
                         but not limited to, in the case of a LIBOR Loan, a
                         change in official reserve requirements, but, in all
                         events, excluding reserves required under Regulation D
                         to the extent included in the computation of the LIBOR
                         Rate) and/or (y) other circumstances affecting the
                         relevant capital market; or

                  (iii)  at any time, that the making or continuance of any
                         LIBOR Loan has become unlawful by compliance by such
                         Lender in good faith with any law, governmental rule,
                         regulation, guideline or order (or would conflict with
                         any such governmental rule, regulation, guideline or
                         order not having the force of law even though the
                         failure to comply therewith would not be unlawful), or
                         has become impracticable as a result of a contingency
                         occurring after the date of this Agreement which
                         materially and adversely affects the relevant capital
                         market;

                                       23
<Page>

then, and in any such event, the Lender so affected (or the Agent, in the case
of clause (i) above) shall on such date give notice to the Borrowers (and the
other Lenders and/or the Agent, as the case may be) of such determination.
Thereafter (x) in the case of clause (i) above, LIBOR Loans shall no longer be
available until such time as the Agent notifies the Borrowers and the Lenders
that the circumstances giving rise to such notice by the Agent no longer exist,
and any Notice of Borrowing delivered pursuant to Section 2.03(a) hereof or
notice of conversion or continuance delivered pursuant to Section 2.08 hereof
with respect to a LIBOR Loan shall be deemed rescinded by the Borrowers, (y) in
the case of clause (ii) above, the Borrowers shall pay to such Lender, upon
written demand therefor, such additional amounts (in the form of an increased
rate of, or a different method of calculating, interest or otherwise as such
Lender in its sole discretion shall determine) as shall be required to
compensate such Lender for such increased costs or reductions in amounts
receivable hereunder (a written notice as to the additional amounts owed to such
Lender, showing in reasonable detail the basis for the calculation thereof,
submitted to the Borrowers by such Lender shall, absent manifest error, be final
and conclusive and binding upon all parties hereto) and (z) in the case of
clause (iii) above, LIBOR Loans shall no longer be available until such time as
such Lender notifies the Borrowers that the circumstances giving rise to such
notice no longer exist, any Notice of Borrowing delivered pursuant to Section
2.03(a) hereof or notice of conversion or continuance delivered pursuant to
Section 2.08 hereof with respect to LIBOR Loans shall be deemed rescinded by the
Borrowers, and any LIBOR Loans that are then outstanding shall be automatically
converted to Base Rate Loans; PROVIDED, HOWEVER that if such Lender, in its sole
discretion, determines that such circumstances can only be alleviated by
repayment of such Loans, then, within thirty (30) days, the Borrowers shall
repay in full such Loans, together with accrued but unpaid interest thereon.

          (b)     CAPITAL ADEQUACY. If after the date hereof, the adoption of
any applicable law, rule or regulation regarding capital adequacy, or any change
therein, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by a Lender or its
parent with any request or directive made or adopted after the date hereof
regarding capital adequacy (whether or not having the force of law) of any such
authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on such Lender's or its parent's capital or assets
as a consequence of such Lender's commitments or obligations hereunder to a
level below that which such Lender or its parent could have achieved but for
such adoption, effectiveness, change or compliance (taking into consideration
such Lender's or its parent's policies with respect to capital adequacy), then
from time to time, upon demand, the Borrowers shall pay to such Lender such
additional amount or amounts as will compensate such Lender or its parent for
such reduction. Such Lender, upon determining in good faith that any additional
amounts will be payable pursuant to this Section 2.14, will give prompt written
notice thereof to the Borrowers, which notice shall set forth in reasonable
detail the basis of the calculation of such additional amounts, although the
failure to give any such notice shall not release or diminish any of the
obligations of the Borrower to pay additional amounts pursuant to this Section
2.14 upon receipt of such notice.

          (c)     FUNDING LOSSES. The Borrowers shall compensate each Lender,
upon its written request (which request shall set forth the basis for requesting
such compensation), for all reasonable losses, expenses and costs, including,
without limitation, any loss, expense or cost

                                       24
<Page>

incurred by reason of the liquidation or reemployment of deposits or other funds
required by such Lender to fund its LIBOR Loans (all such losses "FUNDING
LOSSES") which such Lender may sustain: (x) if for any reason an advance or
continuance of, or conversion from or into, LIBOR Loans does not occur on a date
specified therefor in a Notice of Borrowing or notice of conversion or
continuance given pursuant to Section 2.08(a) or (b) hereof, as the case may be,
(whether or not withdrawn by a Borrower or deemed withdrawn pursuant to Section
2.14(a) hereof); (y) if any repayment (including any prepayment made pursuant to
Section 4.01 or 4.02 hereof) or conversion of any of its LIBOR Loans occurs on a
date which is not the last day of an Interest Period with respect thereto; or
(z) as a consequence of (i) any other default by the Borrowers to repay the
Loans when required by the terms of this Agreement or any Note held by such
Lender or (ii) any prepayment or conversion made pursuant to Section 2.14(a)
hereof. The amount of compensation available to any Lender pursuant to this
Section 2.14(c) hereof shall be determined based on the assumption that such
Lender has funded the entire amount of the relevant LIBOR Loan through match
funding obtained in the London interbank market, but shall be limited to an
amount not to exceed the amount of interest that would have accrued on the
relevant LIBOR Loan through the end of the relevant Interest Period.

          2.15    COMPUTATION. Interest and any fees or compensation based upon
a PER ANNUM rate shall be calculated on the basis of a 360 day year for the
actual number of days elapsed.

          2.16    SECURITY. The Obligations shall be secured by a perfected
first priority security interest (subject only to Permitted Liens) in and to the
Collateral, whether now owned or hereafter acquired, pursuant to the terms of
the Security Agreement.

          2.17    INCREASE OF THE COMMITMENTS AND MAXIMUM AVAILABLE REVOLVING
CREDIT AMOUNT.

          (a)     REQUESTS FOR INCREASE GENERALLY. Provided that at the time of
request contemplated in this Section 2.17 there does not exist an Event of
Default or Default, the Borrowers may request an increase in the Maximum
Available Revolving Credit Amount and a concomitant increase of the Commitments
in an amount not less than $5,000,000 or greater than $10,000,000 in the
aggregate by written notice to the Agent and the Lenders requesting each
Lender's proportional increase, and the Lenders agree to respond to the said
request for an increase within ten (10) calendar days following receipt of same;
PROVIDED, HOWEVER, that the failure of any Lender to respond within such time
period shall not in any manner constitute an agreement by such Lender to said
increase of its Pro Rata Share of its Commitment. If all Lenders elect to
increase the Maximum Available Revolving Credit Amount and their Commitments as
proposed above, each Lender's Commitment shall increase proportionately based on
its Pro Rata Share of said increase, and this Agreement and the relevant Notes
shall be amended to reflect such increases, all at the cost and expense of the
Borrowers. If one or more Lenders decline to so increase their Commitment or do
not respond to said request within the time period set forth above, the
provisions of Section 2.17(b) hereof shall apply.

          (b)     ADDITIONAL INCREASE PROVISIONS. In the event that one or more
Lenders do not agree to the increase of the Maximum Available Revolving Credit
Amount and its

                                       25
<Page>

concomitant Pro Rata Share thereof pursuant to Section 2.17(a) hereof or do not
respond to Borrowers' request for an increase within the time required under
Section 2.17(a) (each a "NON-INCREASING LENDER"), then the Lenders which have
agreed to such increase within the time required under Section 2.17(a) (the
"INCREASING BANKS") may elect to increase their Commitments proportionately up
to the amounts of the Commitments that would have otherwise been assumed by the
Non-Increasing Lender. Any amount of the Commitments not assumed by the
Increasing Lenders pursuant to the immediately preceding sentence is referred to
as the "ADDITIONAL COMMITMENTS". Should there exist any Additional Commitments
not assumed by the Increasing Lenders, then the Agent and the Borrowers may
arrange to have one or more other lenders (each a "NEW INCREASING LENDER") to be
included as a Lender hereunder with respect to the Additional Commitments and
all other rights, interests and obligations of a Lender under this Agreement and
the other Credit Documents. Any such assumption shall be (1) pursuant to an
assumption agreement substantially similar to an Assignment and Assumption
Agreement, (2) subject to and in accordance with this Section 2.17, and (3)
effective on the last day of the Interest Period of any then outstanding LIBOR
Loans. Upon the effectiveness of the increase in the Commitments by the
Increasing Lenders or the New Increasing Lenders, as the case may be, pursuant
to this Section 2.17(b), (i) this Agreement and the relevant Notes shall be
amended and/or restated to reflect the reduction and/or increase of each
Lender's Pro Rata Share of the Commitments contemplated in this Section 2.17(b)
(as determined by the Agent), (ii) the Borrowers will issue new Notes to any New
Increasing Lender to evidence the Borrowers' obligations with respect to such
New Increasing Lender's Commitment, and (iii) each New Increasing Lender shall
be deemed to be a Lender for all purposes of this Agreement and the other Credit
Documents, all at the cost and expense of the Borrowers.

          (c)     NO AMENDMENT FEE. Any modification to this Credit Agreement or
any other Credit Document incidental to compliance with this Section 2.17 shall
not require payment of the amendment fee specified in Section 3.05 hereof.

          SECTION 3. FEES.

          3.01    UNUSED FEE. The Borrowers shall pay to the Agent for the
ratable account of the Lenders based on their respective Pro Rata Shares,
quarterly in arrears, an unused fee for the period from and including the
Closing Date until the Revolving Credit Expiration Date, computed at a rate
equal to the Applicable Margin (expressed as a percentage) of the average daily
amount of the Availability. Such fee shall be payable commencing on June 30,
2002 (for the period commencing on the Closing Date and ending on said June 30,
2002), and continuing quarterly on the last Business Day of each March, June,
September and December occurring thereafter.

          3.02    LETTER OF CREDIT FEE. The Borrowers shall pay to the Agent for
the ratable account of the Lenders based on their respective Pro Rata Share
annually in arrears, a letter of credit fee computed at a rate equal to the
Applicable Margin for LIBOR Loans (expressed as a percentage) of the average
Stated Amount of any Letter of Credit outstanding during the relevant
calculation period. Such fee shall be payable commencing on the Closing Date
(for the period commencing on the Closing Date and ending on March 25, 2003),
and continuing annually on each anniversary of the Closing Date occurring
thereafter.

                                       26
<Page>

          3.03    LETTER OF CREDIT PROCESSING FEE. The Borrowers shall pay to
the Agent for its sole account, upon each issuance of, drawing under, and/or
amendment of, a Letter of Credit, such amounts as shall at the time of such
issuance, drawing or amendment be the administrative charge which the Agent
customarily charges for such issuances of, drawings under or amendments of,
letters of credit issued by it ("LETTER OF CREDIT PROCESSING FEES").

          3.04    AGENT'S FEES. In consideration of the services to be rendered
by the Agent hereunder, the Borrowers shall pay the Agent the agency fees set
forth in a separate fee letter furnished by the Agent to the Borrowers dated
February 8, 2002.

          3.05    AMENDMENT FEE. Upon execution and delivery of any
amendment to this Agreement or any other Credit Document pursuant to Section
11.06 hereof, the Borrowers shall pay to the Agent for the ratable account of
the Lenders based on their respective Pro Rata Shares, an amendment fee of not
less than $15,000.

          SECTION 4. PREPAYMENTS AND PAYMENTS GENERALLY.

          4.01    VOLUNTARY PREPAYMENTS. The Borrowers may prepay any Loan, in
whole or in part, without premium or penalty (except as provided in Section
2.14(c) hereof with respect to LIBOR Loans) upon at least three (3) Business
Days' irrevocable notice to each Lender (or one (1) Business Day's irrevocable
notice in the case of a prepayment of a Base Rate Loan), specifying (i) the date
and the amount of the prepayment (which shall be a Business Day) and (ii)
whether such prepayment is in respect of LIBOR Loans, Base Rate Loans or a
combination thereof; PROVIDED, that any such prepayment shall include all
accrued but unpaid interest in respect of the Loans being prepaid. The principal
portion of any partial prepayment shall be in an amount equal to $500,000 or any
whole multiple.

          4.02    MANDATORY PREPAYMENTS. Immediately upon the sum of (A) the
Revolving Credit Obligations and (B) the Swingline Obligations exceeding the
Maximum Available Credit Amount, the Borrowers shall make, or cause to be made,
a mandatory prepayment of the Revolving Credit Obligations and/or the Swingline
Obligations in an amount equal to such excess, together with accrued but unpaid
interest thereon. Without limiting the foregoing, immediately upon the Letter of
Credit Outstandings exceeding the Letter of Credit Sublimit, the Borrower shall
make, or cause to be made, payment to the Agent in the amount of such excess to
be held as cash collateral (on terms and conditions established by the Agent and
reasonably acceptable to the Borrowers) to secure such Letter of Credit
Outstandings in excess of the Letter of Credit Sublimit. Provided that no
Default or Event of Default has occurred and is then continuing, such cash
collateral shall be released by the Agent (on behalf of the Lenders) if and when
the Letter of Credit Outstandings have been reduced to an amount equal to or
less than the Letter of Credit Sublimit then in effect.

          4.03    APPLICATION OF MANDATORY PREPAYMENTS. Any prepayment received
pursuant to Section 4.02 hereof shall be applied FIRST to reduce the Swingline
Obligations (if any) and SECOND to reduce the Revolving Credit Obligations, and
within this clause second, FIRST to reduce amounts owing in respect of any Base
Rate Loans and SECOND to reduce amounts owing

                                       27
<Page>

in respect of any LIBOR Loans (PROVIDED that, if there is more than one
outstanding LIBOR Loan, then amounts owing in respect of the LIBOR Loans with
the Interest Period ending on the date that is the least number of days from the
date of such prepayment shall be reduced first before reduction of amounts owing
in respect of other LIBOR Loans). Within the order of priority set forth above,
the amount of any prepayment received hereunder shall be applied to the Loans
FIRST to reduce amounts owing in respect of accrued but unpaid interest on the
Loans being prepaid and SECOND to reduce amounts owing in respect of outstanding
principal of such loans. If by operation of the provisions set forth above or
any other reason, payment of principal in respect of a LIBOR Loan is received
(from any source) on a date other than the last day of the Interest Period
pertaining to such Loan, including, without limitation, due to acceleration of
said amount following the occurrence of an Event of Default, then the Borrowers
shall pay to each Lender an additional amount equal to the applicable Funding
Losses. Such Funding Losses shall be payable on demand by such affected Lender.

          4.04    GENERAL PROVISIONS AS TO PAYMENTS. The Borrowers shall make
each payment of principal of, and interest on, the Loans and of fees due
hereunder, not later than 2:00 p.m. (prevailing New York Time) on the date when
due, in immediately available funds to the Agent at its Payment Office. Provided
that the Agent receives such payments by such time, the Agent will distribute to
each Lender on the same day its Pro Rata Share of each such payment received by
the Agent.

          4.05    NET PAYMENTS. All payments made by any Borrower hereunder
shall be made without setoff or counterclaim. All such payments shall be made
free and clear of and without deduction or withholding for, any present or
future taxes, levies, imposts, duties, fees, assessments or other charges of
whatever nature, now or hereafter imposed by any jurisdiction or by any
department, agency, state or other political subdivision or taxing authority
thereof or therein (but excluding any tax imposed on or measured by the net
income of a Lender pursuant to the laws of the jurisdiction in which the
principal office or Payment Office of such Lender is located or under the laws
of any political subdivision or taxing authority of any such jurisdiction in
which the principal office or Payment Office of such Lender is located) and all
interest, penalties, or similar liabilities with respect thereto (collectively,
"TAXES"). If any Taxes are so levied or imposed, each Borrower agrees to pay the
full amount of such Taxes, and such additional amounts as may be necessary so
that every net payment of amounts due hereunder, after withholding or deduction
for or on account of any Taxes, will not be less than the amounts provided for
herein. The Borrowers shall furnish to the Agent, within thirty (30) days after
the date the payment of any Taxes is due pursuant to applicable law, certified
copies of tax receipts evidencing such payment by the Borrowers. Each Borrower
shall indemnify and hold harmless each Lender and reimburse each Lender upon the
written request of such Lender setting forth the basis for requesting such
amount, for the amount of any Taxes so levied or imposed and paid by such
Lender.

          In addition, each Borrower agrees to pay and indemnify and hold
harmless each Lender from and against any present or future stamp or documentary
taxes or any other excise or property taxes, charges or similar levies which
arise from any payment made by the Borrowers or the Agent hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Credit Document.

                                       28
<Page>

          4.06    DEBITING OF ACCOUNT. If so requested by the Agent, each
Borrower shall maintain a demand deposit account (a "DDA ACCOUNT") at the
Payment Office of the Agent, and the Agent may, and each Borrower hereby
authorizes the Agent to, debit any such DDA Account or such other account and/or
certificate of deposit maintained by each Borrower with the Agent for the amount
of any payment, as and when such payment becomes due hereunder, whether such
payment is for accrued interest, principal or expense or otherwise, even if
debiting any such account or certificate of deposit results in a loss or
reduction of interest to each Borrower or the imposition of a penalty applicable
to the early withdrawal of time deposits. Such authorization shall not affect
the Obligation of each Borrower to pay when due all amounts payable hereunder,
whether or not there are sufficient funds in any accounts of any Borrower. The
foregoing rights of the Agent to debit any DDA Account shall be in addition to,
and not in limitation of, any rights of set-off which the Agent or any Lender
may have hereunder or under any Credit Document. Nothing in this Section 4.06 or
otherwise in this Agreement shall be interpreted to obligate the Agent to so
debit, or set-off against, any account of any Borrower maintained with the Agent
to satisfy any of the Obligations of each Borrower, such right to so debit
and/or set-off to be exercised by the Agent in its sole and absolute discretion.

          SECTION 5. CONDITIONS.

          5.01    DOCUMENTS REQUIRED FOR INITIAL ADVANCE. The obligation of each
Lender to make the initial advances under the Revolving Credit Facility
requested on the Closing Date is subject to the satisfaction of all of the
following conditions precedent:

                  Credit Documents, and the names, titles and true signatures of
                  such officers of such Borrower authorized to deliver Notices

                  Borrower;

          (v)     a favorable New Jersey and Delaware law opinion of counsel to

                  this Agreement are true in all material respects;

          (viii)  good standing certificates issued by the appropriate official

          (ix)    such other documents as the Lenders may reasonably require,
                  including, without limitation, other agreements, instruments,

                  hereof are true and correct on and as of the date of funding
                  of each such Loan or date of issuance of such Letter of
                  Credit, as the case may be;

          (ii)    no Default or Event of Default has occurred and is continuing;

          (iii)   there has been no material adverse change in the Borrower's or

          (iv)    all of the Credit Documents remain in full force and effect.

          SECTION 6. REPRESENTATIONS AND WARRANTIES.

          In order to induce the Lenders to enter into this Agreement, each
Borrower represents and warrants with respect to itself and, to the extent
applicable, each of its Subsidiaries, and agrees that each such representation
and warranty shall be deemed to be restated at the time of funding of each Loan
and at the time of issuance of each Letter of Credit, that:

          6.01    ORGANIZATION; AUTHORITY. Each Borrower is duly organized,
validly existing and in good standing under the laws of the state of its
organization, is duly qualified and is in good standing under the laws of each
jurisdiction in which it is required to be qualified because of the business it
conducts or the property it owns, and has the necessary power and authority to
enter into and perform its obligations under the Credit Documents. The execution
and performance of the Credit Documents have been duly authorized by all
necessary and appropriate proceedings on the part of each Borrower, and, upon
their execution and delivery, they will be valid, binding, and enforceable in
accordance with their terms; the execution and performance of the Credit
Documents will not violate any orders, laws or regulations applicable to any
such Borrower, any of their respective organizational documents, or any
instruments, indentures or agreements (including any provisions pertaining to
subordinated debt) to which they are a party or by which any such Borrower or
any of their respective properties are bound;

                                       31
<Page>

and all consents, approvals, licenses, franchises, patents, trademarks and other
general intangibles required in connection with this Agreement, the other Credit
Documents or the operation of any such Borrower's business have been obtained
and are in full force and effect. Each Subsidiary of each Borrower is duly
organized, validly existing, and in good standing under the laws of the
jurisdiction of its organization and is duly qualified and is in good standing
under the laws of each jurisdiction in which it is required to be qualified
because of the business it conducts or the property it owns.

          6.02    USE OF PROCEEDS; MARGIN REGULATION. The proceeds of the
Revolving Credit Loans shall be used only for the following purposes: (i) to
repay all amounts outstanding under the Existing Credit Agreement, (ii) to
finance the consideration payable in connection with acquisitions permitted
pursuant to Section 8.04 hereof; or (iii) in connection with the Borrower's
other working capital needs. The Letters of Credit shall be used solely to
support Permitted L/C Obligations. No Borrower is engaged in the business of
extending credit for the purpose of buying or carrying "margin stock" (within
the meaning of Regulation U issued by the Board of Governors of the Federal
Reserve System). Neither the making of any Loan, the issuance of any Letter of
Credit, nor the use of the proceeds thereof, will violate or be inconsistent
with the provisions of Regulation G, T, U or X of the Board of Governors of the
Federal Reserve System.

          6.03    SPECIFIC FINANCIAL STATEMENTS.

          (a)     There has been furnished to the Agent and each Lender a
consolidated balance sheet of the Borrowers and their Subsidiaries dated the
Balance Sheet Date, and a consolidated statement of operations for the fiscal
year then ended, certified by the Borrowers' independent certified public
accountants. Such balance sheet and statement of operations have been prepared
in accordance with GAAP and fairly present the financial condition of the
Borrowers as at the close of business on the date thereof and the results of
operations for the period then ended. There are no contingent liabilities of the
Borrowers or any of their Subsidiaries as of such date involving material
amounts, known to the officers of any of the Borrowers not disclosed in said
balance sheet and the related notes thereto.

          (b)     The Borrowers (both before and after giving effect to the
transactions contemplated by this Agreement) are solvent, have assets having a
fair value in excess of the amount required to pay their probable liabilities on
their existing debts as they become absolute and matured, and have, and will
have, access to adequate capital for the conduct of their business and the
ability to pay their debts from time to time incurred in connection therewith as
such debts mature.

          (c)     Since the Balance Sheet Date, there have occurred no material
adverse changes in the financial condition or business of the Borrowers and
their Subsidiaries as shown on or reflected in the consolidated balance sheet of
the Borrowers and their Subsidiaries as at the Balance Sheet Date, or the
consolidated statement of operations for the fiscal year then ended other than
changes in the ordinary course of business which have not had any material
adverse effect on the business or financial condition of the Borrowers or their
Subsidiaries considered as a whole. Since the Balance Sheet Date, there has not
been any Distribution by any of the Borrowers.

          6.04    LITIGATION. Except as set forth on ANNEX I hereto, there are
no actions, suits, proceedings or investigations of any kind pending or
threatened against any of the Borrowers or any of their Subsidiaries before any
court, tribunal or administrative agency or board which, if adversely
determined, might, either in any case or in the aggregate, materially adversely
affect the properties, assets, financial condition or business of the Borrowers
and their Subsidiaries, considered as a whole, or materially impair the right of
the Borrowers and their Subsidiaries, considered as a whole, to carry on
business substantially as now conducted, or result in any substantial liability
not adequately covered by insurance, or for which adequate reserves are not
maintained on the consolidated balance sheets of the Borrowers, or which
question the validity of any of the Credit Documents, or any action taken or to
be taken pursuant hereto or thereto.

          6.05    NO MATERIALLY ADVERSE CONTRACTS, ETC. None of the Borrowers
nor any of their Subsidiaries is subject to any charter, partnership agreement,
operating agreement, or corporate or other legal restriction, or any judgment,
decree, order, rule or regulation which in the judgment of the Borrowers'
officers has or is expected in the future to have a materially adverse effect on
the business, assets or financial condition of the Borrowers and their
Subsidiaries as a whole. None of the Borrowers nor any of their Subsidiaries is
a party to any contract or agreement which in the reasonable judgment of the
Borrowers' officers has or is expected to have any materially adverse effect on

otherwise reflected in adequate reserves.

          6.06    COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. None of the
Borrowers nor any of their Subsidiaries is in violation of any provision of
their charter documents or bylaws or any agreement or instrument by which any of
them may be subject or by which any of them or any of their properties may be
bound or any decree, order, judgment, or any statute, license, rule or
regulation, in a manner which could result in the imposition of substantial
penalties or materially and adversely affect the financial condition, properties
or business of any of the Borrowers or any of their Subsidiaries considered as a
whole.

          6.07    ERISA. Each Plan is in substantial compliance with ERISA and
the applicable provisions of the Code and there does not exist with respect to
any such Plan an "accumulated funding deficiency" (as such term is defined in
ERISA). No material liability to the PBGC has been incurred by any Borrower with
respect to any such Plan and no "REPORTABLE EVENT" under ERISA has occurred.
None of the Borrowers nor any of their Subsidiaries has actual or anticipated
liability under Section 4971 of the Code (relating to tax on failure to meet the
minimum funding standard of Section 412 of the Code) with respect to any
Multiemployer Plan. No proceedings have been instituted to terminate any Plan
and no condition exists which presents a material risk to any Borrower or any of
their Subsidiaries of incurring a liability to or on account of any Plan
pursuant to the provisions of ERISA or the applicable provisions of the Code.

          6.08    TAX STATUS. The Borrowers and their Subsidiaries have made or
filed all federal and state income and all other tax returns, reports and
declarations required by any jurisdiction to which any of them are subject

                                       33
<Page>

such Subsidiary has set aside on its books provisions reasonably adequate for
the payment of all unpaid and unreported taxes); and have paid all taxes and
other governmental assessments and charges that are material in amount, shown or
determined to be due on such returns, reports and declarations, except those
being contested in good faith; and have set aside on their books provisions
reasonably adequate for the payment of all taxes for periods subsequent to the
periods to which such returns, reports or declarations apply. There are no
unpaid taxes in any material amount claimed to be due by the taxing authority of
any jurisdiction, and the officers of the Borrowers and their Subsidiaries know
of no basis for any such claim.

          6.09    COMPLIANCE WITH STATUTES, ETC. Each of the Borrowers and their
Subsidiaries is in compliance with all applicable statutes, regulations and
orders of, and all applicable restrictions imposed by, all governmental bodies,
domestic or foreign, in respect of the conduct of its business and the ownership
of its property (including, without limitation, applicable statutes,
regulations, orders and restrictions relating to environmental standards and
controls), EXCEPT such noncompliances as would not, in the aggregate, have a
material adverse effect on the business, operations, property, assets or
financial condition of the Borrowers or their Subsidiaries taken as a whole.

          6.10    NO AUTHORIZATIONS OR APPROVALS. No authorization or approval
or other action by, and no notice to, or filing with, any governmental authority
or regulatory body is required for the due execution, delivery and performance
by any Borrower of this Agreement and the other Credit Documents OTHER than such
authorizations that have been obtain prior to the Closing Date and continue to
be in full force and effect.

          6.11    HOLDING COMPANY AND INVESTMENT COMPANY ACTS. None of the
Borrowers nor any of their Subsidiaries is a "holding company", or an
"affiliate" of a "holding company", as such terms are defined in the Public
Utility Holding Company Act of 1935; nor are any of them a "registered
investment company", or an "affiliated company" or a "principal underwriter" of
a "registered investment company", as such terms are defined in the Investment
Act of 1940, as amended.

          6.12    SUBSIDIARIES. SCHEDULE I hereto lists each Subsidiary of each
Borrower (and the direct or indirect ownership interest of such Borrower
therein), in each case existing on the Closing Date. None of the Borrowers nor
any of their Subsidiaries has any interests in any Person other than as set
forth in said Schedule I. No such Subsidiary has any Subsidiaries.

          6.13    INTELLECTUAL PROPERTY, ETC. Each of the Borrowers and each of
their Subsidiaries have obtained all material patents, trademarks, servicemarks,
trade names, copyrights, technology, processes, licenses and other rights
("INTELLECTUAL PROPERTY"), free from any burdensome restrictions, that are
necessary for the operation of their respective businesses as presently
conducted and as proposed to be conducted. No claim has been asserted or
threatened questioning the use of such Intellectual Property, nor does the
Borrower know of any valid basis for any such claim.

          6.14    LABOR MATTERS. Except as disclosed on ANNEX I, none of the
Borrowers nor any of their Subsidiaries is a party to a labor contract. There
are no strikes,

Subsidiaries have good and marketable title to all of their respective assets
and properties (tangible and intangible) and all such assets and properties are
free and clear of all Liens (except Permitted Liens). Substantially all of the
assets and properties owned by, leased to or used by each Borrower or its
Subsidiaries are in adequate operating condition and repair, ordinary wear and
tear excepted, are free and clear of any known defects EXCEPT such defects as do
not substantially increase with the continued use thereof in the conduct of
normal operation, and such assets are able to serve the function for which they
are currently being used, EXCEPT in each case where the failure of such asset or
property to meet such requirements would not have or is not expected to have a
material adverse effect on the operations of the Borrowers or their
Subsidiaries, taken as a whole.

          6.16    INSURANCE. ANNEX I hereto lists all material insurance
contracts and binders of each Borrower and its Subsidiaries which are currently

Subsidiaries or rights thereunder.

pledges and deposits of documents or instruments required to be made by the
Borrowers hereunder have been made and all other actions have been taken
required to be taken by the Borrowers hereunder to establish and perfect the

Borrowers are the owners of the

                                       35

condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of such Borrower
may be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; PROVIDED, HOWEVER, that
nothing in this Section 7.05 or in Section 7.04 hereof shall prevent any
Borrower from discontinuing the operation and maintenance of any of its
properties or those of its Subsidiaries if such discontinuance is, in the
reasonable judgment of such Borrower, desirable in the conduct of its or their
business and which do not in the aggregate materially adversely affect the
business of the Borrowers and their Subsidiaries on a consolidated basis.

          7.06    INSURANCE. The Borrowers will maintain, and cause their

feasible, and reasonably priced environmental impairment insurance.

          7.07    TAXES. Each Borrower will and will cause each of its

charges imposed by foreign jurisdictions which in the aggregate are not material
to the business or assets of any Borrower on an individual basis or of the
Borrowers and their Subsidiaries on a consolidated basis) imposed upon it and
its real properties, sales and activities, or any part thereof, or upon the
income or profits therefrom, as well as all claims for labor, materials, or
supplies, which if unpaid might by law become a lien or charge upon any of its
property; PROVIDED, HOWEVER, that any such tax, assessment, charge, levy or
claim need not be paid if the validity or amount thereof shall currently be
contested in good faith by appropriate proceedings and if such Borrower or such
Subsidiary shall have set aside on its books adequate reserves with respect
thereto; and provided, further, that such Borrower and such Subsidiary will pay
all such taxes, assessments, charges, levies or claims forthwith upon the
commencement of proceedings to foreclose any lien which may have attached as
security therefor.

          7.08    INSPECTION OF PROPERTIES, BOOKS, AND CONTRACTS. The Borrowers
shall permit the Agent or any Lender or any of their designated representatives,
to visit and inspect any of the properties of the Borrowers or any of their

Subsidiaries and contracts under which any of the Borrowers performs services
(and to make copies thereof and extracts therefrom), and to discuss the affairs,
finances and accounts of the Borrowers and their Subsidiaries with, and to be
advised as to the same by, their officers, all at such reasonable times and
intervals as the Agent or a Lender may reasonably request.

          7.09    COMPLIANCE WITH LAWS, CONTRACTS, LICENSES AND PERMITS. Each

provisions of its charter documents and by-laws and all agreements and
instruments by which it or any of its properties may be bound; and (ii) all
applicable laws and regulations (including Environmental Laws), decrees, orders
and judgments ("APPLICABLE LAWS") except where noncompliance with such
Applicable Laws would not have a material adverse effect in the aggregate on the
financial condition, properties or business of any Borrower or any Subsidiary.
If at any time while any of the Obligations are outstanding or the Agent or any
Lender has any obligation to make Loans or to issue Letters of Credit hereunder,
any authorization, consent, approval, permit or license from any officer, agency
or instrumentality of any government shall become necessary or required in order
that any Borrower may fulfill any of its obligations hereunder, such Borrower
will immediately take or cause to be taken all reasonable steps within the power
of such Borrower to obtain such authorization, consent, approval, permit or
license and furnish the Agent and each Lender with evidence thereof.

                  agreement or shall have commenced any corporate proceedings in
                  furtherance of a Change of Control, OTHER than a Change of

                                       49
<Page>

                  result of the sale of equity interests in such Immaterial
                  Subsidiary within the limits set forth in Section 8.06 hereof;

then, and in any such event, and at any time thereafter, if any Event of Default
shall then be continuing the Agent shall, upon the written request of the
Required Lenders, by written notice to the Borrowers, take any or all of the
following actions, without prejudice to the rights of the Agent or any Lender to
enforce its claim against any Borrower, except as otherwise specifically
provided for in this Agreement (PROVIDED that, if an Event of Default specified
in clause (v), (vi), (vii) or (viii) above shall occur with respect to any
Borrower, the result which would occur upon the giving of written notice by the
Agent as specified in clauses (i) and (ii) below shall occur automatically
without the giving of any such notice): (i) declare all of the Commitments
terminated, whereupon the Commitment of each Lender shall forthwith terminate
immediately and any fees theretofore accrued shall forthwith become due and
payable without any other notice of any kind; (ii) declare the principal of and
any accrued interest in respect of all Obligations to be, whereupon the same
shall become, forthwith due and payable without presentment, demand, protest or
other notice of any kind, all of which are hereby waived by each Borrower; (iii)
terminate any Letter of Credit which may be terminated in accordance with its
terms; and (iv) direct the Borrowers to pay (and each Borrower agrees that upon
receipt of such notice, or upon the occurrence of an Event of Default as
specified in clause (v) (vi), (vii) or (viii) above, it will pay) to the Agent
such additional amounts of cash to be held as cash collateral for the
reimbursement obligations of the Borrowers for Drawings that may subsequently
occur under any Letter of Credit then outstanding, equal to the Stated Amount of
all such Letters of Credit.

          Notwithstanding anything contained in the foregoing paragraph, if at
any time within sixty (60) days after an acceleration of the Loans pursuant to
the preceding paragraph, the Borrowers shall pay all arrears of interest and all
payments on account of principal which shall have become due otherwise than by
acceleration (with interest on principal and, to the extent permitted by law, on
overdue interest, at the rates specified in the Credit Documents) and all Events
of Default (other than non-payment of the principal of and accrued interest on
the Loans, in each case which is due and payable solely by virtue of
acceleration) shall be remedied or waived to the satisfaction of the Required
Lenders, then the Required Lenders, by written notice to the Borrowers, shall
rescind and annul the acceleration and its consequences; but such action shall
not affect any subsequent Event of Default or impair any right consequent
thereon. The provisions of this paragraph are intended merely to bind the
Lenders to a decision which may be made at the election of the Lenders and are
not intended to benefit any Borrower and do not grant any. Borrower the right to
require the Lenders to rescind or annul any acceleration hereunder, even if the
conditions set forth herein are met. Without limiting the generality of the
remedies available to the Lenders pursuant to the Credit Documents or by law
following an Event of Default, the rate of interest on the principal portion of
the Obligations shall be increased to a rate equal to the Default Rate.

          9.02    RIGHT OF SET-OFF. If any of the Obligations shall be due and
payable or any one or more Events of Default shall have occurred, whether or not
any Lender shall have made demand under any Credit Document and regardless of
the adequacy of any collateral or other form of security for the Obligations or
other means of obtaining repayment of the Obligations, each Lender shall have
the right, without notice to any Borrower or any other Obligor, and is

                                       50
<Page>

specifically authorized hereby to set-off against and apply to the then unpaid
balance of the Obligations any items or funds of any Borrower and/or any Obligor
held by each Lender or any Affiliate of such Lender, any and all deposits
(whether general or special, time or demand, matured or unmatured) or any other
property of any Borrower and/or any Obligor, including, without limitation,
securities and/or certificates of deposit, now or hereafter maintained by any
Borrower and/or any Obligor for its or their own account with any Lender or any
Affiliate thereof, and any other indebtedness at any time held or owing by the
Lender or any Affiliate to or for the credit or the account of any Borrower
and/or any Obligor, even if effecting such set-off results in a loss or
reduction of interest or the imposition of a penalty applicable to the early
withdrawal of time deposits. For such purpose, each Lender shall have, and each
Borrower hereby grants to each Lender, a first Lien on and security interest in
such deposits, property, funds and accounts and the proceeds thereof.

          9.03    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 in excess of its Pro
Rata Share of payments on account of the Loans obtained by all the Lenders, such
Lender shall forthwith purchase from the other Lenders such participations in
the Loans made by them 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 Pro Rata Share
according to the proportion of (i) the amount of such Lender's required
repayment to (ii) 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. Each Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section 9.03
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Lender were the direct creditor of such Borrower in the amount of such
participation. The foregoing shall in no way obligate any Lender to seek payment
in respect of the Obligations of such Borrower hereunder through such Lender's
right of set-off or otherwise at any time, or in any particular order relative
to such other rights or remedies such Lender may possess, in a manner that
prejudices or impairs (as determined in such Lender's sole discretion) any other
right or remedy such Lender may possess to enforce claims against any Borrower
in respect of Obligations of the Borrowers hereunder or such other Obligations
of any Borrower owed to such Lender.

          9.04    TURNOVER OF PROPERTY HELD BY AFFILIATE. Each Borrower further
authorizes each Affiliate of any Lender, upon and following the occurrence of an
Event of Default, at the request of the Lender so affiliated, and without notice
to such Borrower, to turn over to such Lender any property of such Borrower,
including, without limitation, funds and securities, held by such Affiliate for
such Borrower's account and to debit, for the benefit of such Lender, any
deposit account maintained by such Borrower with such Affiliate (even if such
deposit account is not then due or there results a loss or reduction of interest
or the imposition of a penalty in accordance with law applicable to the early
withdrawal of time deposits), in the

                                       51
<Page>

amount requested by such Lender up to the amount of the Obligations, and to pay
or transfer such amount or property to such Lender for application to the
Obligations.

          9.05    REMEDIES CUMULATIVE; NO WAIVER. The rights, powers and
remedies of the Agent and the Lenders provided in this Agreement and any of the
other Credit Documents are cumulative and not exclusive of any right, power or
remedy provided by law or equity. No failure or delay on the part of the Agent
or any of the Lenders in the exercise of any right, power or remedy shall
operate as a waiver thereof, nor shall any single or partial exercise preclude
any other or further exercise thereof, or the exercise of any other right, power
or remedy.

     SECTION 10. THE AGENT.

          10.01   APPOINTMENT. Each Lender hereby irrevocably designates and
appoints First Union National Bank as the Agent of such Lender under this
Agreement, and each such Lender irrevocably authorizes First Union National
Bank, as the Agent for such Lender, to take such action on its behalf under the
provisions of this Agreement and to exercise such powers and perform such duties
as are expressly delegated to the Agent by the terms of this Agreement and the
other Credit Documents, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement, the Agent shall not have any duties or responsibilities, except
those expressly set forth herein, or any fiduciary relationship with any Lender,
and no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Credit Document or
otherwise exist against the Agent.

          10.02   DELEGATION OF DUTIES. The Agent may execute any of its duties
under this Agreement by or through agents or attorneys-in-fact and shall be
entitled to advice of counsel concerning all matters pertaining to such duties.
The Agent shall not be responsible for the negligence or misconduct of any
agents or attorneys in-fact selected by it with reasonable care.

          10.03   EXCULPATORY PROVISIONS. Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(i) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Agreement or any other Credit Document
(except for its or such Person's own gross negligence or willful misconduct) or
(ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by any Borrower or any officer
thereof contained in this Agreement or any other Credit Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection with, this Agreement or any
other Credit Document or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or the Notes or any other Credit
Document or for any failure of any Borrower to perform its obligations hereunder
or thereunder. The Agent shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Credit
Document, or to inspect the property, books or records of the Borrowers.

                                       52
<Page>

          10.04   RELIANCE BY AGENT. The Agent shall be entitled to rely, and
shall be fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, or any other form of written,
electronic or telephonic message, statement, order or other document, or
conversation or communication believed by it in good faith to be genuine and
correct and to have been signed, sent, made or transmitted by a Responsible
Officer and upon advice and statements of legal counsel (including, without
limitation, counsel to any Borrower), independent accountants and other experts
selected by the Agent. The Agent may deem and treat the payee of any Note as the
owner thereof for all purposes unless a written notice of assignment,
negotiation or transfer thereof shall have been filed with the Agent. The Agent
shall be fully justified in failing or refusing to take any action under this
Agreement or any other Credit Document unless it shall first receive such advice
or concurrence of the 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 Agent shall in all cases be fully protected in acting, or
in refraining from acting, under this Agreement and the Notes and the other
Credit Documents in accordance with a request of the Lenders, and such request
and any action taken or failure to act pursuant thereto shall be binding upon
all the Lenders and all future holders of the Notes. Without limiting the
generality of the foregoing, no Lender shall have any right of action whatsoever
against the Agent as a result of the Agent acting or refraining from acting
hereunder or under any other Credit Documents in accordance with the
instructions of the Lenders.

          10.05   NOTICE OF DEFAULT. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Event of Default unless the Agent
has received notice from a Lender or any Borrower referring to this Agreement,
describing such Event of Default and stating that such notice is a "notice of
default". In the event that the Agent receives such a notice, the Agent shall
give notice thereof to the Lenders. The Agent shall take such action with
respect to such Event of Default as shall be reasonably directed by the Lenders;
PROVIDED that unless and until the Agent shall have received such directions,
the Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Event of Default as it shall deem
advisable in the best interests of the Lenders.

          10.06   NON-RELIANCE ON AGENT AND OTHER LENDERS. Each Lender expressly
acknowledges that neither the 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 Agent taken, including any review of
the affairs of the Borrower, shall be deemed to constitute any representation or
warranty by the Agent to any Lender. Each Lender represents to the Agent that it
has, independently and without reliance upon the 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, operations, property,
financial and other condition and creditworthiness of each Borrower and made its
own decision to make its Loans hereunder and enter into this Agreement. Each
Lender also represents that it will, independently and without reliance upon the
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
the other Credit Documents, and to make such investigation as it deems necessary
to inform itself as to the business, operations, property, financial and other
condition and creditworthiness of each

                                       53
<Page>

Borrower. Except for notices, reports and other documents expressly required to
be furnished to the Lenders by the Agent hereunder, the Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, operations, property, condition (financial
or otherwise), prospects or creditworthiness of each Borrower which may come
into the possession of the Agent or any of its officers, directors, employees,
agents, attorneys-in-fact or Affiliates.

          10.07   INDEMNIFICATION. The Lenders agree to indemnify the Agent in
its capacity as such (to the extent not reimbursed by the Borrowers and without
limiting the obligation of the Borrowers to do so), ratably according to their
Pro Rata Shares 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 payment of the Notes) be imposed on, incurred by or
asserted against the Agent in any way relating to or arising out of this
Agreement, any of 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 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 resulting solely from the
Agent's gross negligence or willful misconduct. If, however, the Agent shall
have been reimbursed by the Borrowers in respect of any amounts previously paid
to the Agent by the Lenders pursuant to this Section 10.07, then the Agent shall
pay to the Lenders their Pro Rata Shares of such duplicative reimbursement. The
agreements in this subsection shall survive the payment of the Notes and all
other amounts payable hereunder.

          10.08   AGENT IN ITS INDIVIDUAL CAPACITY. The Agent and its Affiliates
may make loans to, accept deposits from and generally engage in any kind of
business with any Borrower as though the Agent were not the Agent hereunder and
under the other Credit Documents. With respect to its Loans made or renewed by
it and any Note issued to it, the Agent shall have the same rights and powers
under this Agreement and the other Credit Documents as any Lender and may
exercise the same as though it were not the Agent, and the terms LENDER and
LENDERS shall include the Agent in its individual capacity.

          10.09   SUCCESSOR AGENT. The Agent may resign as Agent upon thirty
(30) days' notice to the Lenders. If the Agent shall resign as Agent under this
Agreement, then the Lenders shall appoint from among the Lenders a successor
agent for the Lenders, which successor agent shall be approved by the Borrower.
If a successor Agent shall not have been so appointed within said thirty (30)
day period, the Agent shall appoint from among the Lenders a successor agent for
the Lenders. Any such successor agent shall succeed to the rights, powers and
duties of the Agent, and the term AGENT shall mean such successor agent
effective upon its appointment, and the former Agent's rights, powers and duties
as Agent shall be terminated, without any other or further act or deed on the
part of such former Agent or any of the parties to this Agreement or any holders
of the Notes. After any retiring Agent's resignation as Agent, the provisions of
this Section 10 shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was the Agent under this Agreement.

          Any notice required to be delivered to a Borrower, shall be deemed
given to each Borrower when so given to any Borrower in accordance with the
delivery instructions stated above. Any notice given by a Borrower hereunder
shall be deemed given by each Borrower, and the Agent and the Lenders are
entitled to rely on said notice of any Borrower as if communicated by, and
received from, each Borrower.

          11.02   COSTS AND EXPENSES. Whether or not the transactions
contemplated by the Credit Documents are fully consummated, the Borrowers shall
promptly pay (or reimburse, as the Agent and/or any of the Lenders, as the case
may be, may elect) all costs and expenses which the Agent or the Lenders have
incurred or may hereafter incur in connection with the negotiation, preparation,
reproduction, interpretation, perfection, monitoring, administration and
enforcement of the Credit Documents, the collection of all amounts due under the
Credit Documents, and all amendments, modifications, consents or waivers, if
any, to the Credit Documents. Such costs and expenses shall include, without
limitation, the fees and disbursements of counsel to the Agent and/or any of the
Lenders, the costs of appraisals, costs of environmental studies, searches of
public records, costs of filing and recording documents with public offices,
internal and/or external audit and/or examination fees and costs, stamp, excise
and other taxes and costs and expenses incurred by the Agent or any of the
Lenders, and the fees of

                                       55
<Page>

the accountants, consultants or other professionals engaged by the Agent or the
Lenders in connection with the transactions contemplated in this Agreement and
the other Credit Documents. Without limiting the generality of the foregoing,
the Borrower shall reimburse the Agent for the costs and expenses of counsel to
the Agent, for services rendered in consideration with the preparation and
negotiation of the Credit Documents and matters related thereto. Such
reimbursement shall be payable on the Closing Date. The Borrower's reimbursement
obligations under this paragraph shall survive any termination of the Credit
Documents.

          11.03   PAYMENT DUE ON A DAY OTHER THAN A BUSINESS DAY. If any payment
due or action to be taken under this Agreement or any other Credit Document
falls due or is required to be taken on a day that is not a Business Day, such
payment or action shall be made or taken on the next succeeding Business Day and
such extended time shall be included in the computation of interest.

          11.04   GOVERNING LAW. This Agreement shall be construed in accordance
with and governed by the substantive laws of the State of New Jersey without
reference to conflict of laws principles.

          11.05   COUNTERPARTS; INTEGRATION. This Agreement may be signed in any
number of counterparts, each of which shall be an original, with the same effect
as if the signatures thereto and hereto were on the same instrument. This
Agreement and the other Credit Documents constitute the sole agreement of the
parties with respect to the subject matter hereof and thereof and supersede all
oral negotiations and prior writings with respect to the subject matter hereof
and thereof.

          11.06   AMENDMENT OR WAIVER. Neither this Agreement nor any other
Credit Document nor any terms hereof or thereof may be changed, waived,
discharged or terminated unless such change, waiver, discharge or termination is
in writing signed by the Required Lenders; PROVIDED, that no such change,
waiver, discharge or termination shall, without the consent of each Lender, (i)
extend the final maturity of any Loan or Note, or any portion thereof, or reduce
the rate or extend the time of payment of interest (other than as a result of
waiving the applicability of any post-default increase in interest rates)
thereon or fees payable hereunder or reduce the principal amount thereof, or
increase the Commitment of any Lender over the amount thereof then in effect (it
being understood that a waiver of any Default or Event of Default or of a
mandatory reduction in the Commitment shall not constitute a change in the terms
of the Credit Commitment of any Lender), (ii) release all or substantially all
of collateral at such time securing the Obligations (except as expressly
provided in such instruments pertaining to such collateral), (iii) the release
of any guaranty at any time supporting the Obligations, (iv) amend, modify or
waive any provision of this Section, or Section 2.12, 2.13, 4.05, 9.01, 9.02,
9.03, 11.02, 11.08 or 11.11; (v) reduce any percentage specified in, or
otherwise modify, the definition of Required Lenders; (vi) alter or amend any
provision hereof expressly requiring the consent, satisfaction or acceptance of
all of the Lenders; or (vii) consent to the assignment or transfer by any
Borrower of any of its rights and obligations under this Agreement. No provision
of Section 10 hereof may be amended without the consent of the Agent. The
provisions of Sections 2.09, 2.10, 2.11, 2.12 and 2.13 shall not be amended or
modified in any way that adversely affects the Agent with respect to its
obligation to issue Letters of Credit, without the Agent's consent.

          11.07   SUCCESSORS AND ASSIGNS. This Agreement (i) shall be binding
upon each Borrower, the Agent and the Lenders and their successors and permitted
assigns, and (ii) shall inure to the benefit of each Borrower, the Agent and the
Lenders and their respective successors and permitted assigns; PROVIDED,
HOWEVER, that no Borrower may assign its rights hereunder or any interest herein
without the prior written consent of the Lenders, and any such assignment or
attempted assignment by the Borrower shall be void and of no effect with respect
to the Lenders.

          11.08   PARTICIPATIONS AND ASSIGNMENTS. Each Borrower hereby
acknowledges and agrees that each Lender may at any time: (I) grant
participations in all or any portion of its rights and obligations hereunder
(including, without limitation, its obligation to make advances hereunder in
accordance with its Commitment) or under its Revolving Credit Note
(collectively, "PARTICIPATIONS") to any other lending office or to any other
bank, lending institution or other entity which has the requisite sophistication
to evaluate the merits and risks of investments in Participations (each a
"PARTICIPANT"); PROVIDED, HOWEVER, that: (i) all amounts payable by the
Borrowers hereunder shall be determined as if such Lender had not granted such
Participation, and (ii) such Lender (A) shall retain the sole right and
responsibility to enforce the obligations of the Borrower hereunder including,
without limitation, the right to approve any amendment, modification or waiver
of any provisions of this Agreement; and (B) shall not in any event be relieved
from its obligations to make advances hereunder in accordance with its
Commitment; PROVIDED, HOWEVER, that such Lender may agree with the Participant
that such Lender will not agree to any modification, amendment or waiver of this
Agreement without the consent of the Participant if such amendment, modification
or waiver would reduce the principal of or rate of interest on the Obligations
so participated or postpone the date fixed for any payment of principal of or
interest on such Obligations; and (II) assign up to one hundred percent (100%)
of its rights and obligations hereunder (including, without limitation, its
obligation to make advances hereunder in accordance with its Commitment) or
under its Revolving Credit Note; PROVIDED, HOWEVER, that, except with respect to
assignments between and among Lenders which are parties to this Agreement (as to
which the conditions in clauses (i) through (iii) below shall not be applicable)
prior to such assignment: (i) it has obtained the prior written consent of the
Agent (which consent shall not be unreasonably withheld) and has delivered to
the Agent and the Borrowers a duly completed and executed assignment and
assumption agreement in the form attached hereto as EXHIBIT F (as "ASSIGNMENT
AND ASSUMPTION AGREEMENT"); (ii) the amount assigned shall be an amount equal to
$5,000,000 or multiples of $1,000,000 in excess thereof; and (iii) such Lender
has paid to the Agent a transfer fee of $3,500. Notwithstanding anything in this
Section 11.08 to the contrary, each Lender may sell or assign, in whole or in
part, any or all of its interest in the Obligations (without the consent of any
Person or any other restriction) to (i) any Affiliate of such Lender, (ii) any
Federal Reserve Bank in connection with a pledge of said interest as collateral
security pursuant to Regulation A of the Board of Governors of the Federal
Reserve System, and (iii) any Person at any time after an Event of Default. The
holder of any sale, assignment or Participation permitted pursuant to this
Section 11.08, if the applicable agreement between the relevant Lender and such
holder so provides, (i) shall be entitled to all of the rights, obligations and
benefits of a Lender hereunder and (ii) shall be deemed to hold and may exercise
the rights of set-off or banker's lien with respect to any and all obligations
of such holder to the Borrower, in each case as fully as though the Borrowers
were directly indebted to such holder. Each Borrower authorizes each Lender to

                                       57
<Page>

provide information concerning such Borrower to any prospective purchaser,
assignee or participant. The information provided may include, but is not
limited to, amounts, terms, balances, payment history, and any financial or
other information about such Borrower. Each Borrower agrees to indemnify,
defend, and release any Lender that has so disclosed such information, and hold
such Lender harmless, at such Borrower's cost and expense, from and against any
and all lawsuits, claims, actions, proceedings, or suits against such Lender
arising out of or relating to such Lender's reporting or disclosure of such
information.

          11.09   SEVERABILITY. The illegality or unenforceability of any
provision of this Agreement or any instrument or agreement required hereunder
shall not in any way affect or impair the legality or enforceability of the
remaining provisions of this Agreement or any instrument or agreement required
hereunder. In lieu of any illegal or unenforceable provision in this Agreement,
there shall be added automatically as a part of this Agreement a legal and
enforceable provision as similar in terms to such illegal or unenforceable
provision as may be possible.

          11.10   CONSENT TO JURISDICTION AND SERVICE OF PROCESS. Each Borrower
irrevocably appoints each and every Responsible Officer (or higher ranking
officer) of the Borrower as its attorneys upon whom may be served, by regular or
certified mail at the address of TRC set forth in this Agreement, any notice,
process or pleading in any action or proceeding against it arising out of or in
connection with this Agreement or any of the other Credit Documents. Each
Borrower hereby consents that any action or proceeding against it may be
commenced and maintained in any court within the State of New Jersey or in the
United States District Court for the District of New Jersey by service of
process on any such officer. Each Borrower further agrees that such courts of
the State of New Jersey and the United States District Court for the District of
New Jersey shall have jurisdiction with respect to the subject matter hereof and
the person of such Borrower and all collateral for the Obligations.
Notwithstanding the foregoing, each Borrower agrees that any action brought by a
Borrower (or all of them) shall be commenced and maintained only in a court in
the federal judicial district or county in which the Agent has its principal
place of business in New Jersey.

          11.11   CONFIDENTIALITY; PUBLICITY. The Agent and each Lender shall
hold, and shall cause its Participants and prospective Participants, if any, to
agree to hold, all non-public information obtained pursuant to the requirements
of any Credit Document which has been identified as such by the Borrowers in
accordance with its customary procedure for handling confidential information of
such nature and in accordance with safe and sound banking practices and in any
event may make disclosure reasonably required by any BONA FIDE assignee,
transferee or participant or as legally required or reasonably requested by any
governmental agency or representative thereof or pursuant to legal process. The
foregoing notwithstanding, the Borrowers acknowledge and agree that First Union
National Bank and the other Lenders may share with their respective Affiliates
(including, without limitation, First Union Securities, Inc.) any information
relating to the Facility and the Borrowers, but any such sharing of the
information shall be solely for purposes reasonably related to the transaction
contemplated herein. The Borrowers further acknowledge and agree to the
disclosure by First Union National Bank and the other Lenders of information
relating to the Facility to GOLD SHEETS and other

                                       58
<Page>

similar bank trade publications, with such information to consist of deal terms
and other information customarily found in such publications.

          11.12   INDEMNIFICATION.

          (a)     Each Borrower agrees to indemnify the Agent and each Lender,
their respective Affiliates and each of their respective directors, officers,
agents and employees (each an Indemnitee) and hold each Indemnitee harmless from
and against any and all liabilities, losses, damages, costs and expenses of any
kind, including, without limitation, the reasonable fees and disbursements of
counsel, which may be incurred by such Indemnitee in connection with any
investigative, administrative or judicial proceeding (whether or not such
Indemnitee shall be designated a party thereto) brought or threatened relating
to or arising out of this Agreement, the other Credit Documents or any actual or
proposed use of proceeds of Loans hereunder; PROVIDED that no Indemnitee shall
have the right to be indemnified hereunder (i) for such Indemnitee's own gross
negligence or willful misconduct as determined by a court of competent
jurisdiction or (ii) in the case where the dispute from which such claim for
indemnity arose has been adjudicated in a final non-appealable court order or
decision in a manner contradictory to such Indemnitee's claim.

          (b)     If, after receipt of any payment of all or any part of the
Obligations, any Lender is compelled or agrees, for settlement purposes, to
surrender such payment to any person or entity for any reason (including,
without limitation, a determination that such payment is void or voidable as a
preference or fraudulent conveyance, an impermissible set-off, or a diversion of
trust funds), then this Agreement and the other Credit Documents shall continue
in full force and effect, and the Borrower shall be liable for, and shall
indemnify, defend and hold harmless such Lender with respect to, the full amount
so surrendered.

          (c)     The provisions of this subsection shall survive the
termination of this Agreement and the other Credit Documents and shall be and
remain effective notwithstanding the payment of the Obligations, the release of
any security interest, lien or encumbrance securing the Obligations or any other
action which the Lenders may have taken in reliance upon their receipt of such
payment. Any action by the Lenders shall be deemed to have been conditioned upon
any payment of the Obligations having become final and irrevocable.

          11.13   INCONSISTENCIES. The Credit Documents are intended to be
consistent. However, in the event of any inconsistencies between this Agreement
and any of the other Credit Documents, the terms of this Agreement shall govern,
but such inconsistency shall not otherwise affect the validity or enforceability
of such inconsistent Credit Document.

          11.14   HEADINGS. The headings of sections and paragraphs and table of
contents have been included herein for convenience only and shall not be
considered in interpreting this Agreement.

          11.15   EXHIBITS AND ANNEXES. The Exhibits and Annexes attached hereto
and the provisions thereof, are incorporated herein.

          11.16   JUDICIAL PROCEEDING; WAIVERS.

          (i)     EACH PARTY TO THIS AGREEMENT AGREES THAT ANY SUIT, ACTION OR
                  PROCEEDING, WHETHER CLAIM OR COUNTERCLAIM, BROUGHT OR
                  INSTITUTED BY ANY PARTY HERETO OR ANY SUCCESSOR OR ASSIGN OF
                  ANY PARTY, ON OR WITH RESPECT TO THIS AGREEMENT OR ANY OF THE
                  OTHER CREDIT DOCUMENTS OR THE DEALINGS OF THE PARTIES WITH
                  RESPECT HERETO, OR THERETO, SHALL BE TRIED ONLY BY A COURT AND
                  NOT BY A JURY. IN THE EVENT THAT THE FOREGOING WAIVER OF JURY
                  TRIAL BY THE BORROWER IS DETERMINED TO BE INVALID OR
                  UNENFORCEABLE AS A MATTER OF LAW, EACH BORROWER, THE AGENT AND
                  THE LENDERS AGREE THAT THE PROVISIONS OF ANNEX III TO THIS
                  AGREEMENT SHALL GOVERN AS TO THE MATTERS SET FORTH THEREIN.

          (ii)    EACH PARTY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY
                  WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY SUCH SUIT, ACTION
                  OR PROCEEDING. FURTHER, EACH PARTY WAIVES ANY RIGHT IT MAY
                  HAVE TO CLAIM OR RECOVER, IN ANY SUCH SUIT, ACTION OR
                  PROCEEDING, ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL
                  DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL
                  DAMAGES.

          (iii)   EACH BORROWER ACKNOWLEDGES AND AGREES THAT THIS SECTION IS A
                  SPECIFIC AND MATERIAL ASPECT OF THIS AGREEMENT AND THAT THE
                  LENDERS WOULD NOT EXTEND CREDIT TO THE BORROWER IF THE WAIVERS
                  SET FORTH IN THIS SECTION WERE NOT A PART OF THIS AGREEMENT.

          11.17   JOINT AND SEVERAL LIABILITY. For the avoidance of doubt, each
Borrower hereby acknowledges that obligations of each Borrower hereunder are
joint and several entitling the Agent and the Lenders to enforce said
obligations against any Borrower or all of the Borrowers in the sole and
absolute discretion of the Agent or the Lenders, as the case may be. The
obligation of each Borrower hereunder, and under each other Credit Document, are
primary and independent obligations of such Borrower, and not the obligations of
a surety, guarantor, or endorsement or accommodation party. Notwithstanding the
foregoing, any claims, defenses, rights or procedure requirements that would
inure to the benefit of any Borrower as a surety, guarantor, or endorsement or
accommodation party with respect to the enforcement of such obligations are, to
the fullest extent permissible under applicable law, expressly waived and
released by each Borrower.

          11.18   EXECUTION CERTIFICATION. Each Borrower hereby certifies that
this Agreement, each of the Notes and each of the other Loan Documents to which
it is a party were executed by each Borrower and delivered to the Agent in the
State of New Jersey.

                                       61

          IN WITNESS WHEREOF, the Borrowers have caused this Agreement to be
duly executed and delivered by its officers duly authorized as of the date first
above written.

Dear Bernie:

         This letter (the "Agreement") shall serve to amend, restate and confirm
the understandings contained in our November 1, 2000 letter agreement. WorldCom,
Inc. (the "Company") and you have entered into various contractual arrangements
respecting certain of your obligations that are, or have been, secured by shares
of the Company, to wit:

                  (i) Limited Guaranty dated as of November 14, 2000 executed by
the Company for the benefit of Bank of America, N.A. (the "Prior Guaranty");

                  (ii) Limited Guaranty dated as of February 12, 2001 executed
by the Company for the benefit of Bank of America, N.A., as modified by that
certain First Modification and Reaffirmation of Limited Guaranty, dated as of
January 25, 2002, replacing the Prior Guaranty (items (i) and (ii), together
with any amendments, modifications, supplements or replacements thereof, are
sometimes collectively referred to herein as the "Guaranty");

                  (iii) Promissory Note dated as of September 8, 2000 in the
maximum principal amount of $25 million made by you payable to the order of the
Company;

                  (iv) Promissory Note dated as of November 1, 2000 in the
maximum principal amount of $25 million made by you payable to the order of the
Company;

                  (v) Promissory Note dated as of December 29, 2000 in the
maximum principal amount of $50 million made by you payable to the order of the
Company;

                  (vi) Promissory Note dated as of September 10, 2001 made by
you payable to the order of the Company relating to the Guaranty; and

                  (vii) Promissory Note dated as of January 30, 2002 in the
maximum principal amount of $65 million made by you payable to the order of the
Company (items (iii) through (vii), together with any amendments, modifications,
supplements, or replacements thereof, are sometimes hereinafter collectively
referred to as the "Promissory Notes").

         1. INDEMNITY. You shall indemnify, reimburse and hold harmless the
Company for any amounts expended, losses, damages, costs, claims or expenses
(including, but not limited to, court costs and attorneys' fees) under or
arising out of the Guaranty, this Agreement or the Promissory Notes.

         2. PLEDGE. (a) To secure the prompt payment and full performance of all
obligations owing by you to the Company (the "Liabilities"), whether direct,
contingent, fixed or otherwise, now or from time to time hereafter arising, with
respect to this Agreement, the Promissory Notes and the

Guaranty, you have granted and/or hereby grant to the Company a security
interest in and to, and pledge and assign to the Company, under Articles 8 and 9
of the Uniform Commercial Code as currently effective in the State of
Mississippi, all of your right, title, share and interest in the shares of stock
of the Company now owned by you (except for the stock of the Company currently
the subject of pledges for the benefit of Citibank, N.A. and Bank of America,
N.A., respectively, pursuant to agreements in effect on November 1, 2000, or any
renewals, replacements, amendments, modifications, or extensions thereof,
hereinafter, the "Existing Pledges"), or hereafter acquired by you pursuant to
the exercise of stock options, together with all proceeds thereof and amounts or
other securities or property derived therefrom, and, upon the release of the
Existing Pledges, you shall be deemed to have granted to the Company a security
interest under Articles 8 and 9 of the Uniform Commercial Code as currently
effective in the State of Mississippi in such additional shares of stock in the
Company as were the subject of the Existing Pledges (all of the shares
referenced above are sometimes hereinafter collectively referred to as the
"Collateral"). You agree to keep the Collateral free from any lien, security
interest or encumbrance other than those in favor of the Company, or arising out
of the Existing Pledges, or as to which the Company consents in writing.

                  (b) Upon demand by the Company pursuant to any one or more of
the Promissory Notes (which shall be subject to a majority vote of the Board of
Directors of the Company) or upon the breach by you of any of the terms of this
Agreement or any of the Promissory Notes, the Company may exercise the rights
and pursue the remedies provided under Article 9 of the Uniform Commercial Code
as currently effective in, or as hereafter amended by, the State of Mississippi,
including but not limited to exercising all voting rights with respect to the
Collateral, collecting all dividends and other distributions with respect to the
Collateral, and selling the Collateral at any public or private sale, at the
Company's option, without advertisement; provided, however, that upon any such
demand, you shall have 90 days from the date thereof to make payment; provided,
further, that if such demand is made subsequent to your death or incapacity,
your estate shall have 180 days from the date thereof to make payment; in either
such case, interest shall continue to accrue at the "Normal Rate" as provided in
the Promissory Notes until such payment is due and, until such payment is due,
the Company shall refrain from exercising the aforementioned rights and
remedies. The Company may bid and become a purchaser at any such sale, and upon
any such sale the Company shall collect, receive, and hold and apply the
proceeds as provided herein. If notice of intended disposition is required by
law, such notice, if mailed, shall be deemed reasonably and properly given if
mailed to your address appearing on the records of the Company at least five
days before the time of such disposition. The proceeds from any such sale or
action shall be applied first to the payment of all legal and other costs and
expenses incurred in connection with the sale or action and next to the payment
of the Liabilities, as determined by the Company. The balance, if any, of such
proceeds remaining after such application shall be paid to you. If the proceeds
of any such sale or action are insufficient to pay in full the amounts specified
above, you shall remain liable for such deficiency.

         3. PERFECTION. To perfect the Company's security interest in the
Collateral, (a) you hereby irrevocably authorize the Company at any time and
from time to time to file in any appropriate jurisdiction any UCC financing
statements or amendments thereto, and (b) you are delivering to the Company
certain of the Collateral, together with irrevocable stock powers endorsed in
blank. You, from time to time hereafter, shall deliver to the Company any
additional Collateral that comes within your possession or control, together
with irrevocable stock powers endorsed in blank.

         4. ADDITIONAL SECURITY. You represent and warrant to the Company that
your personal financial statement dated December 31, 2001 (the "Statement")
provided to the Company is complete and

<PAGE>

Page 3

accurate in all material respects and, except as noted on the Statement, all of
the assets listed thereon are owned by you individually, free and clear of any
liens, security interests or other encumbrances, except for statutory liens
securing immaterial amounts arising in the ordinary course of business. On or
within 10 days of the date hereof, you agree to provide such information with
respect to your interests in Joshua Holdings LLC, BC Yacht Sales Inc., Savannah
Yacht & Ship LLC, BCT Real Estate LLC, Douglas Lake Land & Timber Company LLP
and Douglas Lake Properties, Inc., together with any related or subsidiary
entities (the "Additional Assets"), and as the Company reasonably may request
from time to time, including without limitation:

                  (i) Outstanding debt and liability information with respect to
     each Additional Asset;

                  (ii) Existing appraisal information, evaluations and title
     reports with respect to each Additional Asset; and

                  (iii) Historical operating statements for each Additional
     Asset.

Except for liens in existence as of the date hereof, until the Liabilities have
been paid in full, you will not sell, assign, transfer, pledge or encumber in
any other matter any of the Additional Assets without the prior written consent
of the Company. On or within 10 days of the date hereof, you shall pledge to the
Company (and shall cause the pledge by related minority investors) of a security
or mortgage interest in each of the Additional Assets. In the event that the
value of the Collateral or the Additional Assets should materially increase in
the aggregate during the term of this Agreement, the Company will take
reasonable steps to release that portion of the Collateral and/or Additional
Assets that is no longer necessary to sufficiently collateralize the
Liabilities.

         5. FURTHER ASSURANCES. You agree to perform all acts and do all things
which the Company may request, now or hereafter, in order to evidence, preserve
or protect its rights and the creation, attachment or perfection of the security
interests granted or to be granted hereunder including, without limitation,
execution and delivery of one or more promissory notes evidencing your
obligations arising out of any advance under the Guaranty and delivery of stock
certificate(s) with appropriate stock powers in order to perfect the Company's
security interest in the Collateral or the Additional Assets.

         6. MISCELLANEOUS. This Agreement shall be interpreted and the rights
and liabilities of the parties hereto shall be determined in accordance with the
internal laws (as opposed to the conflicts of law provisions) and decisions of
the State of Mississippi and you hereby consent to the jurisdiction of the
courts of or in the State of Mississippi in connection with any dispute,
controversy, action or other matter relating to or arising out of this
Agreement. Whenever possible each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement shall be prohibited by or invalid under
applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Agreement. This Agreement shall be binding
upon you and your heirs and legal representatives and shall inure to the benefit
of the Company and its successors and assigns. The powers, rights, and remedies
of the Company under this Agreement are cumulative and are not exclusive of any
other power, right or remedy that the Company otherwise may have. Any single or
partial exercise or pursuit of any power, right or remedy under this Agreement
by the Company shall not preclude other or further exercise or pursuit thereof
or the exercise or pursuit of any other power, right or remedy. The Company's
rights and remedies under this Agreement shall be unaffected by any change in
the provisions of

<PAGE>

any agreement, instrument, or document evidencing or affecting any of the
Liabilities, by any extension of time for payment or performance of any of the
Liabilities or by any partial or full release of any security for payment or
performance of any of the Liabilities. No delay by the Company in exercising or
pursuing any power, right or remedy under this Agreement shall operate as a
waiver thereof, and no failure by the Company to exercise or pursue any power,
right or remedy shall prevent the Company from exercising the same in the
future.
