                                CREDIT AGREEMENT


To each of the Lenders party hereto


Ladies and Gentlemen:

         The undersigned, Hub Group, Inc., a Delaware corporation (the "Public
Hub Company"), Hub City Terminals, Inc., a Delaware corporation ("Hub Chicago"),
and Hub Holdings, Inc. a Delaware corporation ("Hub Holdings") (Hub Chicago and
Hub Holding being hereinafter referred to collectively as the "Borrowers" and
individually as a "Borrower"), applies to you (the "Lenders") for your several
commitments, subject to the terms and conditions hereof and on the basis of the
representations and warranties hereinafter set forth, to extend credit to each
Borrower, all as more fully hereinafter set forth.


SECTION 1.               THE CREDITS.

             Section 1.1. Revolving Credit. Subject to the terms and conditions
hereof, each Lender severally agrees to extend a revolving credit (the
"Revolving Credit") to the Borrowers which may be availed of by either Borrower
from time to time during the period from and including the date hereof to but
not including the Termination Date, at which time the commitments of the Lenders
to extend credit under the Revolving Credit shall expire. The Revolving Credit
may be utilized by the Borrowers in the form of Revolving Credit Loans and
Letters of Credit, all as more fully hereinafter set forth, provided that the
aggregate principal amount of Revolving Credit Loans and Letters of Credit
outstanding at any one time shall not exceed the Available Commitments (computed
after giving effect to any use of such credit concurrent with its extension
hereunder to repay the Milwaukee Hub Debt). During the period from and including
the date hereof to but not including the Termination Date, each Borrower may use
the Commitments by borrowing, repaying and reborrowing Revolving Credit Loans in
whole or in part and/or by having the Agent issue Letters of Credit, having such
Letters of Credit expire or otherwise terminate without having been drawn upon
or, if drawn upon, reimbursing the Agent for each such drawing, and having the
Agent issue new Letters of Credit, all in accordance with the terms and
conditions of this Agreement. For purposes of this Agreement, where a
determination of the unused or available amount of the Commitments is necessary,
the Revolving Credit Loans and Letters of Credit shall be deemed to utilize the
Commitments. The obligations of the Lenders hereunder are several and not joint,
and no Lender shall under any circumstances be obligated to extend credit under
the Revolving Credit in excess of its Percentage of the Available Commitments.

             Section 1.2. Revolving Credit Loans. Subject to the terms and
conditions hereof, the Revolving Credit may be availed of by each Borrower in
the form of loans (individually a "Revolving Credit Loan" and collectively the
"Revolving Credit Loans"). Each Borrowing of Revolving Credit Loans shall be



made ratably by the Lenders in proportion to their respective Percentages. Each
Borrowing of Revolving Credit Loans shall be in an amount of $100,000 or such
greater amount which is an integral multiple of $100,000; provided, however,
that a Borrowing of Revolving Credit Loans which bears interest with reference
to the Adjusted LIBOR shall be in such greater amount as is required by Section
2.2 hereof. All Revolving Credit Loans made by a Lender shall be made against
and evidenced by a single Revolving Credit Note of the Borrowers, jointly and
severally, (individually a "Revolving Credit Note" and collectively the
"Revolving Credit Notes") payable to the order of such Lender in the amount of
its Commitment, with each Revolving Credit Note to be in the form (with
appropriate insertions) attached hereto as Exhibit A. Each Revolving Credit Note
shall be dated the date of issuance thereof, be expressed to bear interest as
set forth in Section 2 hereof, and be expressed to mature on the Termination
Date. Without regard to the principal amount of each Revolving Credit Note
stated on its face, the actual principal amount at any time outstanding and
owing by the Borrowers on account thereof shall be the sum of all advances then
or theretofore made thereon less all payments of principal actually received.

             Section 1.3.    Letters of Credit.

           (a) General Terms. Subject to the terms and conditions hereof, the
Revolving Credit may be availed of by each Borrower in the form of standby and
commercial letters of credit issued by the Agent for the account of such
Borrower (individually a "Letter of Credit" and collectively the "Letters of
Credit"), provided that the aggregate amount of Letters of Credit issued and
outstanding hereunder shall not at any time exceed $5,000,000. For purposes of
this Agreement, a Letter of Credit shall be deemed outstanding as of any time in
an amount equal to the maximum amount which has not yet been drawn but could be
drawn thereunder under any circumstances and over any period of time plus any
unreimbursed drawings then outstanding with respect thereto. If and to the
extent any Letter of Credit expires or otherwise terminates without having been
drawn upon, the availability under the Commitments shall to such extent be
reinstated. Each Letter of Credit shall be issued by the Agent, but each Lender
shall be obligated to reimburse the Agent for such Lender's Percentage of the
amount of each draft drawn under a Letter of Credit in accordance with this
Section 1.3 and, accordingly, each Letter of Credit shall be deemed to utilize
the Commitments of all Lenders pro rata in accordance with each Lender's
Percentage.

           (b) Term. Each Letter of Credit issued hereunder shall expire not
later than the earlier of (i) twelve (12) months from the date of issuance (or
be cancelable not later than twelve (12) months from the date of issuance and
each renewal) or (ii) the Termination Date. In the event the Agent issues any
Letter of Credit with an expiration date that is automatically extended unless
the Agent gives notice that the expiration date will not so extend beyond its
then scheduled expiration date, the Agent will give such notice of non-renewal
before the time necessary to prevent such automatic extension if before such
required notice date (i) the expiration date of such Letter of Credit if so
extended would be after the Termination Date, (ii) the Commitments have
terminated or (iii) an Event of Default exists and the Required Lenders have
given the Agent instructions not to so permit the extension of the expiration
date of such Letter of Credit.

                                      -2-


           (c) General Characteristics. Each Letter of Credit issued hereunder
shall be payable in U.S. Dollars, conform to the general requirements of the
Agent for the issuance of standby or commercial letters of credit, as the case
may be, as to form and substance, and be a letter of credit which the Agent may
lawfully issue.

           (d) Applications. At the time either Borrower requests each Letter of
Credit to be issued (or prior to the first issuance of a Letter of Credit in the
case of a continuing application), such Borrower shall execute and deliver to
the Agent an application for such Letter of Credit in the form then customarily
prescribed by the Agent (individually an "Application" and collectively the
"Applications"). Subject to the other provisions of this subsection, the
obligation of such Borrower to reimburse the Agent for drawings under a Letter
of Credit shall be governed by the Application for such Letter of Credit.
Anything contained in the Applications to the contrary notwithstanding, (i) the
Borrowers shall be jointly and severally liable for all obligations in respect
of each Letter of Credit, (ii) in the event the Agent is not reimbursed by the
Borrowers for the amount the Agent pays on any draft drawn under a Letter of
Credit issued hereunder by 11:00 a.m. (Chicago time) on the date when such
drawing is paid, the obligation of the Borrowers to reimburse the Agent for the
amount of such draft paid shall bear interest (which the Borrowers hereby
promise to pay on demand) from and after the date the draft is paid until
payment in full thereof at a fluctuating rate per annum determined by adding 2%
to the Domestic Rate as from time to time in effect (computed on the basis of a
year of 365 days for the actual number of days elapsed), (iii) the Borrowers
shall pay fees in connection with each Letter of Credit as set forth in Section
3 hereof, (iv) except as otherwise provided in Section 3.3 hereof, prior to the
occurrence of a Default or an Event of Default the Agent will not call for
additional collateral security for the obligations of the Borrowers under the
Applications, (v) except as otherwise provided in Section 3.3 hereof, prior to
the occurrence of a Default or an Event of Default the Agent will not call for
the funding of a Letter of Credit by the Borrowers prior to being presented with
a draft drawn thereunder (or, in the event the draft is a time draft, prior to
its due date) and (vi) before making payment on a drawing under a Letter of
Credit, the Agent will notify a Company of such drawing, together with notice of
the amount of such payment and the date such payment is expected to be made
(which payment date may be the same date as such notice is given in the case of
a drawing under a commercial Letter of Credit). The Borrowers hereby irrevocably
authorize the Agent to charge, while any Event of Default is continuing, any of
either Borrower's deposit accounts maintained with the Agent for the amount
necessary to reimburse the Agent for any drafts drawn under Letters of Credit
issued hereunder.

           (e) Change in Laws. If the Agent or any Lender shall determine in
good faith that any change in any applicable law, regulation or guideline
(including, without limitation, Regulation D of the Board of Governors of the
Federal Reserve System) or any new law, regulation or guideline, or any
interpretation of any of the foregoing by any governmental authority charged
with the administration thereof or any central bank or other fiscal, monetary or
other authority having jurisdiction over the Agent or such Lender (whether or
not having the force of law), shall:

                                      -3-


                   (i) impose, modify or deem applicable any reserve, special
         deposit or similar requirement against the Letters of Credit, or the
         Agent's or such Lender's or either Borrower's liability with respect
         thereto; or

                  (ii) impose on the Agent or such Lender any penalty with
         respect to the foregoing or any other condition regarding this
         Agreement, the Applications or the Letters of Credit;

and the Agent or such Lender shall determine in good faith that the result of
any of the foregoing is to increase the actual cost (whether by incurring a cost
or adding to a cost) to the Agent or such Lender of issuing, maintaining or
participating in the Letters of Credit hereunder (without benefit of, or credit
for, any prorations, exemptions, credits or other offsets available under any
such laws, regulations, guidelines or interpretations thereof), then the
Borrowers shall pay within 15 days of demand to the Agent or such Lender from
time to time as specified by the Agent or such Lender such additional amounts as
the Agent or such Lender shall determine are sufficient to compensate and
indemnify it for such increased cost. If the Agent or any Lender makes such a
claim for compensation, it shall provide either Borrower (with a copy to the
Agent in the case of any Lender) a certificate setting forth the computation of
the increased cost as a result of any event mentioned herein in reasonable
detail and such certificate shall constitute prima facie evidence if reasonably
determined.

           (f) Participations in Letters of Credit. Each Lender shall
participate on a pro rata basis in accordance with its Percentage in the Letters
of Credit issued by the Agent, which participation shall automatically arise
upon the issuance of each Letter of Credit. Each Lender unconditionally agrees
that in the event the Agent is not immediately reimbursed by a Borrower for the
amount paid by the Agent on any draft presented under a Letter of Credit, then
in that event such Lender shall pay to the Agent such Lender's Percentage of the
amount of each draft so paid and in return such Lender shall automatically
receive an equivalent percentage participation in the rights of the Agent to
obtain reimbursement from the Borrowers for the amount of such draft, together
with interest thereon as provided for herein. The obligations of the Lenders to
the Agent under this subsection shall be absolute, irrevocable and unconditional
under any and all circumstances whatsoever and shall not be subject to any
set-off, counterclaim or defense to payment which any Lender may have or have
had against any one or more of the Borrowers, the Agent, any other Lender or any
other party whatsoever. In the event that any Lender fails to honor its
obligation to reimburse the Agent for its Percentage of the amount of any such
draft, then in that event (i) each other Lender shall pay to the Agent its pro
rata share of the payment due the Agent from the defaulting Lender, (ii) the
defaulting Lender shall have no right to participate in any recoveries from any
one or more of the Borrowers in respect of such draft and (iii) all amounts to
which the defaulting Lender would otherwise be entitled under the terms of this
Agreement or any of the other Loan Documents shall first be applied to
reimbursing the Lenders for their respective pro rata shares of the defaulting
Lender's portion of the draft, together with interest thereon as provided for
herein. Upon reimbursement to the other Lenders (pursuant to clause (iii) above
or otherwise) of the amount advanced by them to the Agent in respect of the


                                      -4-


defaulting Lender's share of the draft together with interest thereon, the
defaulting Lender shall thereupon be entitled to its pro rata participation in
the Agent's right of recovery against any one or more of the Borrowers in
respect of the draft paid by the Agent.

             Section 1.4. Manner and Disbursement of Revolving Credit Loans.
Either Borrower shall give written or telephonic notice to the Agent (which
notice shall be irrevocable once given and, if given by telephone, shall be
promptly confirmed in writing) by no later than 11:00 a.m. (Chicago time) on the
date such Borrower requests that any Borrowing of Revolving Credit Loans be made
to it under the Commitments, and the Agent shall promptly notify each Lender of
the Agent's receipt of each such notice. Each such notice shall specify the date
of the Borrowing of Revolving Credit Loans requested (which must be a Business
Day), the Borrower making such Borrowing, the type of Loan being requested, and
the amount of such Borrowing. Each Borrowing of Revolving Credit Loans shall
initially constitute part of the Domestic Rate Portion except to the extent such
Borrower has otherwise timely elected that such Borrowing, or any part thereof,
constitute part of a LIBOR Portion as provided in Section 2 hereof. Such
Borrower agrees that the Agent may rely upon any written or telephonic notice
given by any person the Agent in good faith believes is an Authorized
Representative without the necessity of independent investigation and, in the
event any telephonic notice conflicts with the written confirmation, such
telephonic notice shall govern if the Agent and the Lenders have acted in
reliance thereon. Not later than 1:00 p.m. (Chicago time) on the date specified
for any Borrowing of Revolving Credit Loans to be made hereunder, each Lender
shall make the proceeds of its Revolving Credit Loan comprising part of such
Borrowing available to the Agent in Chicago, Illinois in immediately available
funds. Subject to the provisions of Section 7 hereof, the proceeds of each
Revolving Credit Loan shall be made available to the relevant Borrower at the
principal office of the Agent in Chicago, Illinois, in immediately available
funds, upon receipt by the Agent from each Lender of its Percentage of such
Borrowing. Unless the Agent shall have been notified by a Lender prior to 1:00
p.m. (Chicago time) on the date a Borrowing is to be made hereunder that such
Lender does not intend to make the proceeds of its Revolving Credit Loan
available to the Agent, the Agent may assume that such Lender has made such
proceeds available to the Agent on such date and the Agent may in reliance upon
such assumption make available to the relevant Borrower a corresponding amount.
If such corresponding amount is not in fact made available to the Agent by such
Lender and the Agent has made such amount available to such Borrower, the Agent
shall be entitled to receive such amount from such Lender forthwith upon the
Agent's demand, together with interest thereon in respect of each day during the
period commencing on the date such amount was made available to such Borrower
and ending on but excluding the date the Agent recovers such amount at a rate
per annum equal to the effective rate charged to the Agent for overnight federal
funds transactions with member banks of the federal reserve system for each day
as determined by the Agent (or in the case of a day which is not a Business Day,
then for the preceding day). If such amount is not received from such Lender by
the Agent immediately upon demand, the Borrowers will, on demand, repay to the
Agent the proceeds of such Revolving Credit Loan attributable to such Lender
with interest thereon at a rate per annum equal to the interest rate applicable
to the relevant Loan, but without such payment being considered a payment or


                                      -5-


prepayment of a LIBOR Portion, so that the Borrowers will have no liability
under Section 2.9 hereof with respect to such payment.

             Section 1.5. Appointment of Companies as Agents for Borrowers. Each
Borrower hereby irrevocably appoints each of the other Companies as its agent
hereunder to make requests on such Borrower's behalf under Section 1 hereof for
Revolving Credit Loans to be made to such Borrower, to select on such Borrower's
behalf the interest rate to be applicable under Section 2 hereof to Portions of
Revolving Credit Loans made to such Borrower, to receive notices and other
communications sent to it under the Loan Documents and to take any other action
contemplated by the Loan Documents with respect to credit extended hereunder to
such Borrower. The Agent shall be entitled to conclusively presume that any such
action by a Company under the Loan Documents is taken on behalf of any one or
more of the Borrowers whether or not the relevant Borrower so indicates. Nothing
in this Section shall preclude a Borrower from acting on its own behalf.

             Section 1.6. Guaranty Agreements. Payment of the Obligations shall
be guaranteed by each Hub Partnership in which one or more of the Companies own
100% of the equity interest and by each Wholly-Owned Subsidiary, in each case
pursuant to a Guaranty Agreement.

           (a) Portions. Subject to the terms and conditions of this Section 2,
portions of the principal indebtedness evidenced by the Revolving Credit Notes
(all of the indebtedness evidenced by Revolving Credit Notes of the same type
bearing interest at the same rate for the same period of time being hereinafter
referred to as a "Portion") may, at the option of either Borrower, bear interest
with reference to the Domestic Rate ("Domestic Rate Portions") or with reference
to the Adjusted LIBOR ("LIBOR Portions") and Portions may be converted from time
to time from one basis to another. All of the indebtedness evidenced by
Revolving Credit Notes of the same type which is not part of a LIBOR Portion
shall constitute a single Domestic Rate Portion. All of the indebtedness
evidenced by Revolving Credit Notes of the same type which bears interest with
reference to a particular Adjusted LIBOR for a particular Interest Period shall
constitute a single LIBOR Portion. There shall not be more than 3 LIBOR Portions
applicable to Revolving Credit Notes of the same type outstanding at any one
time, and each Lender shall have a ratable interest in each Portion based on its
Percentage. Anything contained herein to the contrary notwithstanding, the
obligation of the Lenders to create, continue or effect by conversion any LIBOR
Portion shall be conditioned upon the fact that at the time no Default or Event
of Default shall have occurred and be continuing. The Borrowers hereby jointly
and severally promise to pay interest on each Portion at the rates and times
specified in this Section 2.

           (b) Domestic Rate Portion. The Domestic Rate Portion shall bear
interest at the rate per annum equal to the Domestic Rate as in effect from time
to time, provided that if the Domestic Rate Portion or any part thereof is not


                                      -6-


paid when due (whether by lapse of time, acceleration or otherwise) such Portion
shall bear interest, whether before or after judgment, until payment in full
thereof at the rate per annum determined by adding 2% to the Domestic Rate as
from time to time in effect. Interest on the Domestic Rate Portion shall be
payable quarterly in arrears on the last day of each March, June, September and
December in each year (commencing September 30, 1997) and at maturity of the
applicable Revolving Credit Notes, and interest after maturity (whether by lapse
of time, acceleration or otherwise) shall be due and payable upon demand. Any
change in the interest rate on the Domestic Rate Portion resulting from a change
in the Domestic Rate shall be effective on the date of the relevant change in
the Domestic Rate.

           (c) LIBOR Portions. Each LIBOR Portion shall bear interest for each
Interest Period selected therefor at a rate per annum determined by adding the
Applicable Margin to the Adjusted LIBOR for such Interest Period, provided that
if any LIBOR Portion is not paid when due (whether by lapse of time,
acceleration or otherwise) such Portion shall bear interest, whether before or
after judgment, until payment in full thereof through the end of the Interest
Period then applicable thereto at the rate per annum determined by adding 2% to
the interest rate which would otherwise be applicable thereto, and effective at
the end of such Interest Period such LIBOR Portion shall automatically be
converted into and added to the Domestic Rate Portion and shall thereafter bear
interest at the interest rate applicable to the Domestic Rate Portion after
default. Interest on each LIBOR Portion shall be due and payable on the last day
of each Interest Period applicable thereto and, with respect to any Interest
Period applicable to a LIBOR Portion in excess of three months, on the date
occurring every three months after the date such Interest Period began and at
the end of such Interest Period, and interest after maturity (whether by lapse
of time, acceleration or otherwise) shall be due and payable upon demand. Either
Borrower shall notify the Agent on or before 11:00 a.m. (Chicago time) on the
third Business Day preceding the end of an Interest Period applicable to a LIBOR
Portion whether such LIBOR Portion is to continue as a LIBOR Portion, in which
event the Borrower shall notify the Agent of the new Interest Period selected
therefor, and in the event such Borrower shall fail to so notify the Agent, such
LIBOR Portion shall automatically be converted into and added to the applicable
Domestic Rate Portion as of and on the last day of such Interest Period. The
Agent shall promptly notify each Lender of each notice received from such
Borrower pursuant to the foregoing provision.

             Section 2.2. Minimum LIBOR Portion Amounts. Each LIBOR Portion 
shall be in an amount equal to $500,000 or such greater amount which is an 
integral multiple of $100,000.

             Section 2.3. Computation of Interest. All interest on each LIBOR
Portion shall be computed on the basis of a year of 360 days for the actual
number of days elapsed. All interest on the Domestic Rate Portion shall be
computed on the basis of a year of 365 days (or, in a leap year, 366 days) for
the actual number of days elapsed.

             Section 2.4. Manner of Rate Selection. Either Borrower shall notify
the Agent by 11:00 a.m. (Chicago time) at least 3 Business Days prior to the
date upon which the Borrower requests that any LIBOR Portion be created or that


                                      -7-


any part of the Domestic Rate Portion be converted into a LIBOR Portion (each
notice to specify in each instance the amount thereof and the Interest Period
selected therefor), and the Agent shall promptly notify each Lender of each
notice received from such Borrower pursuant to the foregoing provision. If any
request is made to convert a LIBOR Portion into the other type of Portion
available hereunder, such conversion shall only be made so as to become
effective as of the last day of the Interest Period applicable thereto. All
requests for the creation, continuance and conversion of Portions under this
Agreement shall be irrevocable. Such requests may be written or oral and the
Agent is hereby authorized to honor telephonic requests for creations,
continuances and conversions received by it from any person the Agent in good
faith believes to be an Authorized Representative without the necessity of
independent investigation, the Borrowers hereby jointly and severally
indemnifying the Agent and the Lenders from any liability or loss ensuing from
so acting.

             Section 2.5. Change of Law. Notwithstanding any other provisions of
this Agreement or any Revolving Credit Note, if at any time any Lender shall
determine in good faith that any change in applicable laws, treaties or
regulations or in the interpretation thereof makes it unlawful for such Lender
to create or continue to maintain any LIBOR Portion, it shall promptly so notify
the Agent (which shall in turn promptly notify either Borrower and the other
Lenders) and the obligation of such Lender to create, continue or maintain any
such LIBOR Portion under this Agreement shall terminate if and so long as such
Lender is legally required not to create, continue or maintain such LIBOR
Portion. The Borrowers, on demand, shall, if a Lender is legally required to
discontinue its maintenance of any such LIBOR Portion, thereupon prepay the
outstanding principal amount of the affected LIBOR Portion, together with all
interest accrued thereon and all other amounts payable to affected Lender with
respect thereto under this Agreement; provided, however, that the relevant
Borrower may elect to convert the principal amount of the affected Portion into
the other type of Portion available hereunder, subject to the terms and
conditions of this Agreement.

             Section 2.6. Unavailability of Deposits or Inability to Ascertain
Adjusted LIBOR. Notwithstanding any other provision of this Agreement or any
Revolving Credit Note, if prior to the commencement of any Interest Period, the
Required Lenders shall determine in good faith that deposits in the amount of
any LIBOR Portion scheduled to be outstanding during such Interest Period are
not readily available to such Lenders in the relevant market or, by reason of
circumstances affecting the relevant market, adequate and reasonable means do
not exist for ascertaining Adjusted LIBOR, then such Lenders shall promptly give
notice thereof to the Agent (which shall in turn promptly notify each Borrower
and the other Lenders) and the obligations of the Lenders to create, continue or
effect by conversion any such LIBOR Portion in such amount and for such Interest
Period shall terminate until deposits in such amount and for the Interest Period
selected by the relevant Borrower shall again be readily available in the
relevant market and adequate and reasonable means exist for ascertaining
Adjusted LIBOR.

             Section 2.7. Taxes and Increased Costs. With respect to any LIBOR
Portion, if any Lender shall determine in good faith that any change in any
applicable law, treaty, regulation or guideline (including, without limitation,


                                      -8-


Regulation D of the Board of Governors of the Federal Reserve System) or any new
law, treaty, regulation or guideline, or any interpretation of any of the
foregoing by any governmental authority charged with the administration thereof
or any central bank or other fiscal, monetary or other authority having
jurisdiction over such Lender or its lending branch or the LIBOR Portions
contemplated by this Agreement (whether or not having the force of law), shall:

                   (i) impose, increase, or deem applicable any reserve, special
         deposit or similar requirement against assets held by, or deposits in
         or for the account of, or loans by, or any other acquisition of funds
         or disbursements by, such Lender which is not in any instance already
         accounted for in computing the interest rate applicable to such LIBOR
         Portion;

                  (ii) subject such Lender, any LIBOR Portion or a Revolving
         Credit Note to the extent it evidences such a Portion to any tax
         (including, without limitation, any United States interest equalization
         tax or similar tax however named applicable to the acquisition or
         holding of debt obligations and any interest or penalties with respect
         thereto), duty, charge, stamp tax, fee, deduction or withholding in
         respect of this Agreement, any LIBOR Portion or a Revolving Credit Note
         to the extent it evidences such a Portion, except such taxes as may be
         measured by the overall net income or gross receipts of such Lender or
         its lending branches and imposed by any jurisdiction, or any political
         subdivision or taxing authority thereof, in which such Lender transacts
         business;

                 (iii) change the basis of taxation of payments of principal and
         interest due from any Borrower to such Lender hereunder or under a
         Revolving Credit Note to the extent it evidences any LIBOR Portion
         (other than by a change in taxation of the overall net income or gross
         receipts of such Lender or its lending branches); or

                  (iv) impose on such Lender any penalty with respect to the
         foregoing or any other condition regarding this Agreement, any LIBOR
         Portion, or its disbursement, or a Revolving Credit Note to the extent
         it evidences any LIBOR Portion;

and such Lender shall determine in good faith that the result of any of the
foregoing is to increase the actual cost (whether by incurring a cost or adding
to a cost) to such Lender of creating or maintaining any LIBOR Portion hereunder
or to reduce the amount of principal or interest received or receivable by such
Lender (without benefit of, or credit for, any prorations, exemption, credits or
other offsets available under any such laws, treaties, regulations, guidelines
or interpretations thereof), then the Borrowers shall pay within 15 days of
demand to the Agent for the account of such Lender from time to time as
specified by such Lender such additional amounts as such Lender shall reasonably
determine are sufficient to compensate and indemnify it for such increased cost
or reduced amount. If a Lender makes such a claim for compensation, it shall
provide to either Borrower (with a copy to the Agent) a certificate setting
forth the computation of the increased cost or reduced amount as a result of any
event mentioned herein in reasonable detail and such certificate shall
constitute prima facie evidence if reasonably determined.

                                      -9-


             Section 2.8. Change in Capital Adequacy Requirements. If any Lender
shall determine that the adoption after the date hereof of any generally
applicable law, rule or regulation regarding capital adequacy, or any change in
any existing law, rule or regulation, 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 such Lender (or any of its branches) with any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on such Lender's capital caused directly by such Lender's
obligations hereunder or for the credit which is the subject matter hereof to a
level below that which such Lender could have achieved but for such adoption,
change or compliance (taking into consideration such Lender's policies with
respect to liquidity and capital adequacy) by an amount deemed by such Lender to
be material, then from time to time, within fifteen (15) days after demand by
such Lender, the Borrowers shall pay to the Agent for the account of such Lender
such additional amount or amounts reasonably determined by such Lender as will
compensate such Lender for such reduction. If a Lender makes such a claim for
compensation, it shall provide to either Borrower (with a copy to the Agent) a
certificate setting forth the computation of the amount demanded in reasonable
detail and the amount reflected in such certificate, shall, if reasonably
determined, constitute prima facie evidence.

             Section 2.9. Funding Indemnity. In the event any Lender shall incur
any loss, cost or expense (including, without limitation, any loss (including
loss of profit), cost or expense incurred by reason of the liquidation or
re-employment of deposits or other funds acquired or contracted to be acquired
by such Lender to fund or maintain its part of any LIBOR Portion or the
relending or reinvesting of such deposits or other funds or amounts paid or
prepaid to such Lender) as a result of:

                   (i) any payment of a LIBOR Portion on a date other than the
         last day of the then applicable Interest Period for any reason, whether
         before or after default, and whether or not such payment is required by
         any provisions of this Agreement; or

                  (ii) any failure by either Borrower to create, borrow,
         continue or effect by conversion a LIBOR Portion on the date specified
         in a notice given pursuant to this Agreement;

then, upon the demand of such Lender, the Borrowers shall pay to the Agent for
the account of such Lender such amount as will reimburse such Lender for such
loss, cost or expense. If a Lender requests such a reimbursement, it shall
provide to either Borrower (with a copy to the Agent) a certificate setting
forth the computation of the loss, cost or expense giving rise to the request
for reimbursement in reasonable detail and such certificate shall be conclusive
if reasonably determined.

            Section 2.10. Lending Branch. Each Lender may, at its option, elect
to make, fund or maintain its pro rata share of the Revolving Credit Loans
hereunder at the branches or offices specified on the signature pages hereof or


                                      -10-


on any Assignment Agreement executed and delivered pursuant to Section 11.10
hereof or at such of its branches or offices as such Lender may from time to
time elect; provided, that if a Lender at its option (not when required by this
Agreement) designates an alternative lending office or branch as described
above, to the extent such designation would at the time of such redesignation
require the Borrowers to pay any amounts pursuant to Section 1.3(e), 2.7, 2.8 or
11.1 hereof in excess of that for which the Borrowers would have already been
liable had such alternative office or branch not been used, the Borrowers shall
not be liable for such increased amounts. To the extent reasonably possible, a
Lender will use reasonable commercial efforts available to it to mitigate or
avoid any obligation by the Borrowers to pay any amount pursuant to Section
1.3(e), 2.7 or 2.8 hereof or the occurrence of any circumstances of the nature
described in Section 2.6 hereof, including without limitation the designation of
an alternate branch or funding office with respect to its pro rata share of the
LIBOR Portions to reduce any liability of the Borrowers to such Lender under
Section 2.7 or Section 2.8 hereof or to avoid the unavailability of an interest
rate option under Section 2.6 hereof, so long as such efforts are neither
impractical nor otherwise disadvantageous to the Lender.

            Section 2.11. Discretion of Lenders as to Manner of Funding.
Notwithstanding any provision of this Agreement to the contrary, each Lender
shall be entitled to fund and maintain its funding of all or any part of its
Revolving Credit Notes in any manner it sees fit, it being understood, however,
that for the purposes of this Agreement all determinations hereunder (including,
without limitation, determinations under Sections 2.6, 2.7 and 2.9 hereof) shall
be made as if each Lender had actually funded and maintained each LIBOR Portion
during each Interest Period applicable thereto through the purchase of deposits
in the relevant market in the amount of its pro rata share of such LIBOR
Portion, having a maturity corresponding to such Interest Period, and bearing an
interest rate equal to the LIBOR for such Interest Period.

            Section 2.12. Replacement of Affected Lenders. At any time any
Lender is an Affected Lender, the Borrowers may replace such Lender as a party
to this Agreement with one or more other bank(s) or financial institution(s)
acceptable to the Agent (which acceptance shall not be unreasonably withheld),
such bank(s) or financial institution(s) to have Commitments which total the
Affected Lender's Commitment and are otherwise in such amounts as shall satisfy
Section 11.10 hereof (and upon notice from the Borrowers such Affected Lender
shall assign pursuant to an Assignment Agreement, and without recourse or
warranty, its Commitments, its Loans, its Revolving Credit Note, and all of its
other rights and obligations hereunder to such replacement bank(s) or other
financial institution(s) for a purchase price equal to the sum of the principal
amount of the Loans so assigned, all accrued and unpaid interest thereon and
such Affected Lender's ratable share of all accrued and unpaid commitment and
letter of credit fees and all other Obligations owed to the Affected Lender, but
in any event without any payment of any amounts otherwise payable under Section
2.9 hereof as a result of such Lender receiving payment of any LIBOR Portion
prior to the end of an Interest Period therefor). Any such assumption and
purchase shall be made in accordance with the provisions of Section 11.10 hereof
relating to assignments of Loans and Commitments.

                                      -11-


SECTION 3.               FEES, PREPAYMENTS, TERMINATIONS, AND APPLICATIONS.

             Section 3.1.    Fees.

           (a) Commitment Fee. For the period from and including the date hereof
to but not including the Termination Date, the Borrowers shall pay to the Agent
for the ratable benefit of the Lenders in accordance with their Percentages, a
commitment fee at the Applicable Margin (computed on the basis of a year of 360
days for the actual number of days elapsed) on the average daily unused portion
of the Commitments. Such commitment fee shall be payable quarterly in arrears on
the last day of each March, June, September and December in each year
(commencing December 31, 1997) and on the Termination Date.

           (b) Letter of Credit Fees. Quarterly in arrears, on the last day of
each March, June, September and December in each year (commencing December 31,
1997), the Borrowers shall pay to the Agent for the ratable benefit of the
Lenders, a letter of credit fee computed at the rate of 1/2 of 1% per annum
(computed on the basis of a year of 360 days for the actual number of days
elapsed) on the average daily face amount of Letters of Credit outstanding
during the immediately preceding three (3) months. In addition to the letter of
credit fee called for above, the Borrowers further agrees to pay to the Agent
for its own account such processing and transaction fees and charges as the
Agent from time to time customarily imposes in connection with any amendment,
cancellation, negotiation and/or payment of letters of credit and drafts drawn
thereunder.

           (c) Arrangement Fee. On the date hereof, the Borrowers shall pay 
to the Agent, for its own use and benefit, an arrangement fee as mutually agreed
upon by the Borrowers and the Agent.

             Section 3.2. Voluntary Prepayments. Each Borrower shall have the
privilege of prepaying the Revolving Credit Notes in whole or in part (but if in
part, then in a minimum amount of $100,000) at any time, which shall promptly so
notify the Lenders, by paying to the Agent for the account of the Lenders the
principal amount to be prepaid and if such a prepayment prepays the Revolving
Credit Notes in full and is accompanied by the termination in whole of the
Commitments, accrued interest thereon to the date of prepayment and any amounts
due to the Lenders under Section 2.9 hereof.

             Section 3.3. (a) Commitment Reductions The Borrowers covenant and
agree that if at any time the sum of the then unpaid principal balance of the
Revolving Credit Notes plus the then outstanding amount of Letters of Credit
shall be in excess of the Available Commitments, the Borrowers shall immediately
and without notice or demand pay over the amount of the excess to the Agent for
the account of the Lenders as and for a mandatory prepayment on such
Obligations, with each such prepayment first to be applied to the Revolving
Credit Notes until payment in full thereof with any remaining balance to be held
by the Agent as collateral security for the Obligations owing under the
Applications.

           (b) Mandatory Prepayment. If, within 30 days after receiving notice
under Section 7.5(e) of a Change of Control Event, the Agent or Required Lenders


                                      -12-


notify either Borrower that the Bank requires prepayment of the Revolving Credit
Notes, on the date set forth in such notice (which date shall be no earlier than
(x) 30 days after such notice is given or (y) the day on which any member of the
Hub Group prepays any other Indebtedness for Borrowed Money aggregating in
excess of $500,000 before its original scheduled due date, whichever day is
earlier), the Borrowers shall pay in full all Obligations then outstanding,
including the collateralization of the outstanding Letters of Credit in the
manner contemplated by Section 8.4 hereof, and the Commitments shall terminate
in full.

             Section 3.4. Reduction and Termination of Commitments. (a)
Voluntary. Either Borrower shall have the privilege from time to time upon not
less than one Business Day's prior notice to the Agent (which shall promptly
notify the Lenders) to ratably reduce the Commitments in whole or in part (but
in part then in a minimum amount of $1,000,000 or such greater amount which is
an integral multiple of $100,000), provided that the Commitments may not be
reduced to the extent that after giving effect to such reduction, the aggregate
principal amount of the Revolving Credit Loans and Letters of Credit then
outstanding would exceed the Available Commitments. Any termination of the
Commitments pursuant to this Section may not be reinstated. Any reduction in the
Commitments made pursuant to this Section 3.4(a) shall reduce the amounts of the
Commitments as scheduled to be in force during the period in which the reduction
occurs, and the amount of the Commitments scheduled to be in force for each
period occurring thereafter pursuant to the definition of the term "Commitments"
shall be reduced by a like amount.

           (b) Generally. All reductions in the Commitments (whether voluntary
or mandatory) shall decrease the Commitments (and thus the Available
Commitments) of the Lenders pro rata in accordance with their Percentages.

             Section 3.5. Place and Application of Payments. All payments of
principal, interest, fees and all other Obligations payable hereunder and under
the other Loan Documents shall be made to the Agent at its office at 111 West
Monroe Street, Chicago, Illinois (or at such other place as the Agent may
specify) on the date any such payment is due and payable. Payments received by
the Agent after 11:00 a.m. (Chicago time) shall be deemed received as of the
opening of business on the next Business Day. All such payments shall be made in
lawful money of the United States of America, in immediately available funds at
the place of payment, without set-off or counterclaim. Except as herein
provided, all payments shall be received by the Agent for the ratable account of
the Lenders in accordance with their Percentages and shall be promptly
distributed by the Agent ratably to the Lenders. Unless either Borrower
otherwise directs, principal payments shall be first applied to the Domestic
Rate Portion until payment in full thereof, with any balance applied to the
LIBOR Portions in the order in which their Interest Periods expire.

         Anything contained herein to the contrary notwithstanding, all payments
and collections received in respect of the Obligations by the Agent or any of
the Lenders after the occurrence and during the continuance of an Event of
Default shall be remitted to the Agent and distributed as follows:

                                      -13-

                   (a) first, to the payment of any outstanding reasonable costs
         and expenses incurred by the Agent in protecting, preserving or
         enforcing rights under this Agreement or any of the other Loan
         Documents, and in any event including all reasonable costs and expenses
         of a character which the Borrowers have agreed to pay under Section
         11.5 hereof (such funds to be retained by the Agent for its own account
         unless it has previously been reimbursed for such costs and expenses by
         the Lenders, in which event such amounts shall be remitted to the
         Lenders to reimburse them for payments theretofore made to the Agent);

                   (b) second, to the payment of any outstanding interest or
         other fees or Obligations due under this Agreement or any of the other
         Loan Documents other than for principal, pro rata as among the Agent
         and the Lenders in accord with the amount of such interest and other
         fees or Obligations owing each;

                   (c) third, to the payment of the principal of the Revolving
         Credit Notes and any liabilities in respect of unpaid drawings under
         the Letters of Credit, pro rata as among the Lenders in accord with the
         then respective unpaid principal balances of the Revolving Credit Notes
         and the then unpaid liabilities in respect of unpaid drawings under the
         Letters of Credit;

                   (d) fourth, to the Agent, to be held as collateral security
         for any undrawn Letters of Credit, until the Agent is holding an amount
         of cash equal to the then outstanding amount of all Letters of Credit;
         and

                   (e) fifth, to the Borrowers or to whoever the Agent 
         reasonably determines to be lawfully entitled thereto.

             Section 3.6. Notations. Each Revolving Credit Loan made against a
Revolving Credit Note, the status of all amounts evidenced by a Revolving Credit
Note as constituting part of the Domestic Rate Portion or a LIBOR Portion, and,
in the case of each LIBOR Portion, the rate of interest and Interest Period
applicable to such Portion shall be recorded by the relevant Lender on its books
and records or, at its option in any instance, endorsed on a schedule to its
Revolving Credit Note and the unpaid principal balance and status, rates and
Interest Periods so recorded or endorsed by such Lender shall be prima facie
evidence in any court or other proceeding brought to enforce such Revolving
Credit Note of the principal amount remaining unpaid thereon, the status of the
Revolving Credit Loan or Revolving Credit Loans evidenced thereby and the
interest rates and Interest Periods applicable thereto; provided that the
failure of a Lender to record any of the foregoing shall not limit or otherwise
affect the unconditionally and absolutely joint or several obligation of the
Borrowers to repay the principal amount of each Revolving Credit Note together
with accrued interest thereon. A Lender shall record on a schedule thereto the
status of all amounts evidenced thereby as constituting part of the applicable
Domestic Rate Portion or a LIBOR Portion and, in the case of each LIBOR Portion,
the rate of interest and the Interest Period applicable thereto.

                                      -14-


SECTION 4.               DEFINITIONS; INTERPRETATION.

          Section 4.1.    Definitions.  The following terms when used herein 
shall have the following meanings:

         "Adjusted LIBOR" means a rate per annum determined by the Agent in
accordance with the following formula:

                         Adjusted LIBOR =           LIBOR
                                          100%-Reserve Percentage

"Reserve Percentage" means, for the purpose of computing Adjusted LIBOR, the
maximum rate of all reserve requirements (including, without limitation, any
marginal, emergency, supplemental or other special reserves) imposed by the
Board of Governors of the Federal Reserve System (or any successor) under

SECTION 5.               REPRESENTATIONS AND WARRANTIES.

         The Companies and Guarantors jointly and severally represent and
warrant to the Agent and Lenders as follows:

             Section 5.1. Organization and Qualification. Each Company is duly
organized, validly existing and in good standing as a corporation under the laws
of the state of its incorporation, has full and adequate corporate power to own
its Property and conduct its business as now conducted, and is duly licensed or
qualified and in good standing in each jurisdiction in which the nature of the
business conducted by it or the nature of the Property owned or leased by it
requires such licensing or qualifying, except where the failure to be so
licensed or qualified would not be reasonably likely to have a material adverse
effect on the financial condition, Properties, business or operations of the
Public Hub Company or the Hub Group taken as a whole.

                                      -26-


             Section 5.2. Corporate Authority and Validity of Obligations. Each
Company has full right and authority to enter into this Agreement and the other
Loan Documents to perform all of its obligations hereunder and under the other
Loan Documents and in the case of each Borrower, to make the borrowings herein
provided for and to issue its Revolving Credit Notes in evidence thereof. The
Loan Documents delivered by each Company have been duly authorized, executed and
delivered by such Company and constitute valid and binding obligations of such
Company enforceable in accordance with their terms except as enforceability may
be limited by bankruptcy, insolvency, fraudulent conveyance or similar laws
affecting creditors' rights generally and general principles of equity
(regardless of whether the application of such principles is considered in a
proceeding in equity or at law); and this Agreement and the other Loan Documents
do not, nor does the performance or observance by each Company of any of the
matters and things herein or therein provided for, contravene or constitute a
default under any provision of law or any judgment, injunction, order or decree
binding upon any Company or any provision of the charter, articles of
incorporation or by-laws of any Company or any material covenant, indenture or
agreement of or affecting any Company or any of its Properties, or result in the
creation or imposition of any Lien on any Property of either Company.

             Section 5.3. Hub Group. Each Guarantor is duly organized, validly
existing and in good standing under the laws of the jurisdiction in which it is
incorporated or organized, as the case may be, has full and adequate power to
own its Property and conduct its business as now conducted, and is duly licensed
or qualified and in good standing in each jurisdiction in which the nature of
the business conducted by it or the nature of the Property owned or leased by it
requires such licensing or qualifying, except where the failure to be so
licensed or qualified would not be reasonably likely to have a material adverse
effect on the financial condition, Properties, business or operations of the
Public Hub Company or the Hub Group taken as a whole. The Hub Partnerships and
Subsidiaries (if any) listed on Schedule 5.3 hereto (as updated from time to
time pursuant to Sections 7.13(g) and 7.24 hereof) are the only Affiliates of
the Companies engaged in the business of arranging for the movement of
customers' freight by intermodal container or trailer or by truck. Schedule 5.3
hereto (as so updated) identifies under the appropriate subheading each Hub
Partnership and each Subsidiary (if any), the jurisdiction of its incorporation
or organization, as the case may be, the percentage of issued and outstanding
shares of each class of its capital stock or other equity interests owned by the
Public Hub Company, and, if such percentage is not 100% (excluding directors'
qualifying shares as required by law), a description of each class of its
authorized capital stock and other equity interests and the number of shares of
each class issued and outstanding. All of the outstanding shares of capital
stock and other equity interests of each Guarantor are validly issued and
outstanding and all such shares and other equity interests indicated on Schedule
5.3 (as so updated) as owned by the Public Hub Company or any Guarantor, as the
case may be, are so owned, beneficially and of record, by the Public Hub Company
or such Guarantor in each case free and clear of all Liens. There are no
outstanding commitments or other obligations of any Guarantor to issue, and no
options, warrants or other rights of any Person to acquire, any shares of any
class of capital stock or other equity interests of any Guarantor. Each
Guarantor has full right, power and authority to execute and deliver this
Agreement or a Guaranty Agreement and any other Loan Documents executed by it


                                      -27-


and to perform each and all of the matters and things therein provided for. Each
Loan Document delivered by each Guarantor has been duly authorized, executed and
delivered by such Guarantor and constitutes a valid and binding obligation of
such Guarantor enforceable in accordance with their terms except as
enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance
or similar laws affecting creditors' rights generally and general principles of
equity (regardless of whether the application of such principles is considered
in a proceeding in equity or at law) and the Loan Documents executed by each
Guarantor do not, nor does the performance or observance by any Guarantor of any
of the matters or things therein provided for, contravene any provision of law
or any provision of any charter, articles of incorporation, by-laws, partnership
agreement or articles of organization, as the case may be, of any Guarantor or
any material covenant, indenture or agreement of or affecting the Public Hub
Company or any Guarantor or any of the Public Hub Company's or such Guarantor's
Property, or result in the creation or imposition of any Lien on any of the
Public Hub Company's or such Guarantor's Property.

             Section 5.4. Use of Proceeds; Margin Stock. The Borrowers shall use
all proceeds of the Revolving Credit Loans solely for (i) working capital
purposes in the ordinary course of their respective business, (ii) to finance
the Permitted Acquisitions and (iii) to repay the Milwaukee Hub Debt. Not more
than 25% of the total assets of the Public Hub Company or of any other member of
the Hub Group consist of margin stock (within the meaning of Regulation U of the
Board of Governors of the Federal Reserve System). No part of the proceeds of
any Revolving Credit Loan or any other extension of credit made hereunder will
be used to purchase or carry any such margin stock or to extend credit to others
for the purpose of purchasing or carrying any such margin stock.

             Section 5.5. Financial Reports. The consolidated balance sheet of
the Public Hub Company as at December 31, 1996, and the related consolidated
statements of income, retained earnings and cash flows of the Public Hub Company
for the fiscal year then ended, and accompanying notes thereto, which financial
statements are accompanied by the audit report of Arthur Andersen LLP,
independent public accountants, and the unaudited interim consolidated balance
sheet of the Public Hub Company as at June 30, 1997, and the related
consolidated statements of income, retained earnings and cash flows of the
Public Hub Company for the six months then ended, heretofore furnished to the
Lenders, fairly present the consolidated financial condition of the Public Hub
Company as at said dates and the consolidated results of their operations and
cash flows for the periods then ended in conformity with GAAP applied on a
consistent basis. Neither the Public Hub Company nor any other member of the Hub
Group has contingent liabilities which are material to it other than as
indicated on such financial statements or, with respect to future periods, on
the financial statements furnished pursuant to Section 7.5 hereof.

             Section 5.6. No Material Adverse Change. Since June 30, 1997,
except as disclosed in periodic SEC filings by the Public Hub Company, there has
been no change in the condition (financial or otherwise) or business prospects
of the Public Hub Company or the Hub Group, taken as a whole, except those
occurring in the ordinary course of business, none of which individually or in
the aggregate have been materially adverse.

                                      -28-


             Section 5.7. Full Disclosure. The statements and information
furnished to the Lenders in connection with the negotiation of this Agreement
and the other Loan Documents and the commitment by the Lenders to provide all or
part of the financing contemplated hereby do not, taken as a whole and other
than financial projections or forecasts, contain any untrue statements of a
material fact or omit a material fact necessary to make the material statements
contained herein or therein not misleading, the Lenders acknowledging that as to
any projections furnished to the Lenders, the Companies and Hub Partnerships
only represent that the same were prepared on the basis of information and
estimates the Companies believed to be reasonable.

             Section 5.8. Good Title. The members of the Hub Group each have
good title to their assets as reflected on the most recent consolidated balance
sheet of the Public Hub Company furnished to the Lenders (except for sales of
assets by the Hub Group in the ordinary course of business), subject to no Liens
other than such thereof as are permitted by Section 7.12 hereof.

             Section 5.9. Litigation and Other Controversies. Except as
disclosed in periodic SEC filings by the Public Hub Company, there is no
litigation or governmental proceeding or labor controversy pending, nor to the
knowledge of the Public Hub Company threatened, against the Public Hub Company
or any other member of the Hub Group which if adversely determined would (a)
impair the validity or enforceability of, or impair the ability of any member of
the Hub Group to perform its obligations under, this Agreement or any other Loan
Document or (b) result in any material adverse change in the financial
condition, Properties, business or operations of the Public Hub Company or the
Hub Group taken as a whole.

            Section 5.10. Taxes. All tax returns with respect to any income tax

all taxes, assessments, fees and other governmental charges upon the Public Hub
Company or any other member of the Hub Group or upon any of their respective
Properties, income or franchises, which are shown to be due and payable in such
returns, have been paid. The Companies do not know of any proposed additional
tax assessment against any member of the Hub Group for which adequate provision
in accordance with GAAP has not been made on its accounts. Adequate provisions
in accordance with GAAP for taxes on the books of the Public Hub Company and
each other member of the Hub Group have been made for all open years, and for
its current fiscal period.

            Section 5.11. Approvals. No authorization, consent, license, or
exemption from, or filing or registration with, any court or governmental
department, agency or instrumentality, nor any approval or consent of the
stockholders of any Company or any other Person, is or will be necessary to the
valid execution, delivery or performance by any Company of this Agreement or any
other Loan Document.

            Section 5.12. Affiliate Transactions. Neither the Public Hub Company
nor any other member of the Hub Group is a party to any contracts or agreements


                                      -29-


with any of its Affiliates on terms and conditions which are less favorable (x)
in the case of any transaction between any Borrower and any Affiliate, to such
Borrower than would be usual and customary in similar contracts or agreements
between Persons not affiliated with each other, (y) in the case of a transaction
between any Wholly-Owned Guarantor and an Affiliate (other than a Borrower), to
such Guarantor than would be usual and customary in similar contracts or
agreements between Persons not affiliated with each other and (z) in the case of
a transaction between any member of the Hub Group (other than a Company or a
Wholly-Owned Guarantor) and an Affiliate (other than a Company or a Wholly-Owned
Guarantor), to such member of the Hub Group than would be usual and customary in
similar contracts or agreements between Persons not affiliated with each other.

whole. Neither the Public Hub Company nor any other member of the Hub Group has
received written notice to the effect that its operations are not in compliance
with any of the requirements of applicable federal, state or local
environmental, health and safety statutes and regulations or are the subject of
any governmental investigation evaluating whether any remedial action is needed
to respond to a release of any toxic or hazardous waste or substance into the

a material adverse effect on the financial condition, Properties, business or
operations of the Public Hub Company or the Hub Group taken as a whole.

SECTION 9.               THE AGENT

             Section 9.1. Appointment and Authorization. Each Lender hereby
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers hereunder and under the other Loan Documents as are
designated to the Agent by the terms hereof and thereof together with such
powers as are reasonably incidental thereto. The Lenders expressly agree that
the Agent is not acting as a fiduciary of the Lenders in respect of the Loan
Documents, the Company or otherwise, and nothing herein or in any of the other
Loan Documents shall result in any duties or obligations on the Agent or any of


                                      -47-


the Lenders except as expressly set forth herein. Subject to the appointment of
a successor Agent as specified below, the Agent may resign at any time by
sending 20 days prior written notice to any Company and the Lenders. In the
event of any such resignation, the Required Lenders may appoint a new agent with
(except if any Event of Default then exists) the consent of the Public Hub
Company (which consent shall not be unreasonably withheld), which shall succeed
to all the rights, powers and duties of the Agent hereunder and under the other
Loan Documents. Any resigning Agent shall be entitled to the benefit of all the
protective provisions hereof with respect to its acts as an agent hereunder, but
no successor Agent shall in any event be liable or responsible for any actions
of its predecessor. If the Agent resigns and no successor is appointed, the
rights and obligations of such Agent shall be automatically assumed by the
Required Lenders and the Companies shall be directed to make all payments due
each Lender hereunder directly to such Lender.

             Section 9.2. Rights as a Lender. The Agent has and reserves all of
the rights, powers and duties hereunder and under the other Loan Documents as
any Lender may have and may exercise the same as though it were not the Agent
and the terms "Lender" or "Lenders" as used herein and in all of such documents
shall, unless the context otherwise expressly indicates, include the Agent in
its individual capacity as a Lender.

             Section 9.3. Standard of Care. The Lenders acknowledge that they
have received and approved copies of the Loan Documents and such other
information and documents concerning the transactions contemplated and financed
hereby as they have requested to receive and/or review. The Agent makes no
representations or warranties of any kind or character to the Lenders with
respect to the validity, enforceability, genuineness, perfection, value, worth
or collectibility hereof or of the Revolving Credit Notes or any of the other
Obligations or of any of the other Loan Documents. Neither the Agent nor any
director, officer, employee, agent or representative thereof (including any
security trustee therefor) shall in any event be liable for any clerical errors
or errors in judgment, inadvertence or oversight, or for action taken or omitted
to be taken by it or them hereunder or under the other Loan Documents or in
connection herewith or therewith except for its or their own gross negligence or
willful misconduct. The Agent shall incur no liability under or in respect of
this Agreement or the other Loan Documents by acting upon any notice,
certificate, warranty, instruction or statement (oral or written) of anyone
(including anyone in good faith believed by it to be authorized to act on behalf
of the Companies), unless it has actual knowledge of the untruthfulness of same.
The Agent may execute any of its duties hereunder by or through employees,
agents, and attorneys-in-fact and shall not be answerable to the Lenders for the
default or misconduct of any such agents or attorneys-in-fact selected with
reasonable care. The Agent shall be entitled to advice of counsel concerning all
matters pertaining to the agencies hereby created and its duties hereunder, and
shall incur no liability to anyone and be fully protected in acting upon the
advice of such counsel. The Agent shall be entitled to assume that no Default or
Event of Default exists unless notified to the contrary by a Lender. The Agent
shall in all events be fully protected in acting or failing to act in accord
with the instructions of the Required Lenders. The Agent shall in all cases be
fully justified in failing or refusing to act hereunder unless it shall be
indemnified to its satisfaction by the Lenders against any and all liability and
expense which may be incurred by the Agent by reason of taking or continuing to


                                      -48-


take any such action. The Agent may treat the owner of any Revolving Credit Note
as the holder thereof until written notice of transfer shall have been filed
with the Agent signed by such owner in form satisfactory to the Agent. Each
Lender acknowledges that it has independently and without reliance on the Agent
or any other Lender and based upon such information, investigations and
inquiries as it deems appropriate made its own credit analysis and decision to
extend credit to the Company. It shall be the responsibility of each Lender to
keep itself informed as to the creditworthiness of the Company and the Agent
shall have no liability to any Lender with respect thereto.

             Section 9.4. Costs and Expenses. Each Lender agrees to reimburse
the Agent for all costs and expenses suffered or incurred by the Agent or any
security trustee in performing its duties hereunder and under the other Loan
Documents, or in the exercise of any right or power imposed or conferred upon
the Agent hereby or thereby, to the extent that the Agent is not promptly
reimbursed for same by the Companies, all such costs and expenses to be borne by
the Lenders ratably in accordance with the amounts of their respective
Commitments. If any Lender fails to reimburse the Agent for such Lender's share
of any such costs and expenses, such costs and expenses shall be paid pro rata
by the remaining Lenders, but without in any manner releasing the defaulting
Lender from its liability hereunder.

             Section 9.5. Indemnity. The Lenders shall ratably, in accordance
with its Percentage, indemnify and hold the Agent, and its directors, officers,
employees, agents and representatives (including as such any security trustee
therefor) harmless from and against any liabilities, losses, costs and expenses
suffered or incurred by them hereunder or under the other Loan Documents or in
connection with the transactions contemplated hereby or thereby, regardless of
when asserted or arising, except to the extent they are promptly reimbursed for
the same by the Companies and except to the extent that any event giving rise to
a claim was caused by the gross negligence or willful misconduct of the party
seeking to be indemnified. If any Lender defaults in its obligations hereunder,
its share of the obligations shall be paid pro rata by the remaining Lenders,
but without in any manner releasing the defaulting Lender from its liability
hereunder.


SECTION 10.              JOINT AND SEVERAL LIABILITY AND GUARANTIES.

            Section 10.1. Joint and Several Liability and Guaranties. To induce
the Lenders to provide the credit described herein and in consideration of
benefits expected to accrue to each Guarantor by reason of the Commitments and
for other good and valuable consideration, receipt of which is hereby
acknowledged, each Company and each Hub Partnership in which 100% of the equity
interest is owned, directly or indirectly, on or at any time after the date
hereof by one or more of the Companies and each Wholly-Owned Subsidiary and each
other member of the Hub Group which executes and delivers a Guaranty Agreement
(the Companies and such other members of the Hub Group being hereinafter
referred to individually as a "Guarantor" and collectively as the "Guarantors")
hereby unconditionally and irrevocably guarantee jointly and severally to the
Agent, the Lenders and each other holder of any of the Obligations, and each
Borrower hereby unconditionally and irrevocably agrees to be jointly and
severally liable to the Agent, the Lenders and such holders for, the due and
punctual payment of all present and future indebtedness of the Borrowers
evidenced by or arising out of the Loan Documents, including, but not limited


                                      -49-


to, the due and punctual payment of principal of and interest on the Revolving
Credit Notes and the due and punctual payment of all other Obligations now or
hereafter owed by the Borrowers under the Loan Documents as and when the same
shall become due and payable, whether at stated maturity, by acceleration or
otherwise, according to the terms hereof and thereof. In case of failure by the
Borrowers punctually to pay any indebtedness or other Obligations guarantied
hereby or for which the Borrowers agree hereby to be jointly and severally
liable, each Guarantor hereby unconditionally agrees jointly and severally to
make such payment or to cause such payment to be made punctually as and when the
same shall become due and payable, whether at stated maturity, by acceleration
or otherwise, and as if such payment were made by the Borrowers.

            Section 10.2. Guaranty Unconditional. The obligations of each
Guarantor as a guarantor or joint and several obligor under the Loan Documents,
including this Section 10, shall be unconditional and absolute and, without
limiting the generality of the foregoing, shall not be released, discharged or
otherwise affected by:

                   (a) any extension, renewal, settlement, compromise, waiver or
         release in respect of any obligation of any Borrower or of any other
         Guarantor under this Agreement or any other Loan Document or by
         operation of law or otherwise;

                   (b) any modification or amendment of or supplement to this 
         Agreement or any other Loan Document;

                   (c) any change in the corporate existence, structure or
         ownership of, or any insolvency, bankruptcy, reorganization or other
         similar proceeding affecting, the Borrowers, any other Guarantor, or
         any of their respective assets, or any resulting release or discharge
         of any obligation of any Borrower or of any other Guarantor contained
         in any Loan Document;

                   (d) the existence of any claim, set-off or other rights which
         the Guarantor may have at any time against the Agent, any Lender or any
         other Person, whether or not arising in connection herewith;

                   (e) any failure to assert, or any assertion of, any claim or
         demand or any exercise of, or failure to exercise, any rights or
         remedies against any Borrower, any other Guarantor or any other Person
         or Property;

                   (f) any application of any sums by whomsoever paid or 
         howsoever realized to any obligation of any Borrower, regardless of 
         what obligations of the Borrowers remain unpaid;

                   (g) any invalidity or unenforceability relating to or against
         any Borrower or any other Guarantor for any reason of this Agreement or
         of any other Loan Document or any provision of applicable law or


                                      -50-


         regulation purporting to prohibit the payment by the Borrowers or any
         other Guarantor of the principal of or interest on any Revolving Credit
         Note or any other amount payable by them under the Loan Documents; or

                   (h) any other act or omission to act or delay of any kind by
         the Agent, any Lender or any other Person or any other circumstance
         whatsoever that might, but for the provisions of this paragraph,
         constitute a legal or equitable discharge of the obligations of the
         Guarantors under the Loan Documents.

            Section 10.3. Discharge Only Upon Payment in Full; Reinstatement in
Certain Circumstances. Each Guarantor's obligations under this Section 10 shall
remain in full force and effect until the Commitments are terminated and the
principal of and interest on the Revolving Credit Notes and all other amounts
payable by the Borrowers under this Agreement and all other Loan Documents shall
have been paid in full. If at any time any payment of the principal of or
interest on any Revolving Credit Note or any other amount payable by the
Borrowers under the Loan Documents is rescinded or must be otherwise restored or
returned upon the insolvency, bankruptcy or reorganization of any Borrower or of
any Guarantor, or otherwise, each Guarantor's obligations under this Section 10
with respect to such payment shall be reinstated at such time as though such
payment had become due but had not been made at such time.

            Section 10.4.  Waivers. (a) General.  Each Guarantor irrevocably 
waives acceptance hereof, presentment, demand, protest and any notice not 
provided for herein, as well as any requirement that at any time any action be 
taken by the Agent, any Lender or any other Person against the Borrowers, 
another Guarantor or anyother Person.

           (b) Subrogation and Contribution. Each Guarantor hereby agrees not to
exercise or enforce any right of exoneration, contribution, reimbursement,
recourse or subrogation available to such Guarantor against any Person liable
for payment of the Obligations, or as to any security therefor, unless and until
the full amount owing on the Obligations has been paid and the Commitments have
terminated; and the payment by such Guarantor of any amount pursuant to any of
the Loan Documents on account of credit extended to any other Borrower shall not
in any way entitle such Guarantor to any right, title or interest (whether by
way of subrogation or otherwise) in and to any of the Obligations or any
proceeds thereof or any security therefor unless and until the full amount owing
on the Obligations has been paid and the Commitments have terminated.

            Section 10.5. Limit on Recovery. Notwithstanding any other provision
hereof or of the Revolving Credit Notes, the right of recovery against each
Guarantor under this Section 10 or against a Borrower on the Revolving Credit
Notes issued by it shall not (to the extent required by or as may be necessary
or desirable to ensure the enforceability against such Guarantor of its
obligations hereunder or thereunder in accordance with the laws of the
jurisdiction of its incorporation or where it carries on business) exceed (x)
the amount which would render such Guarantor's obligations under this Section 10
and the Revolving Credit Notes void or voidable under applicable law, including
without limitation fraudulent conveyance law minus (y) $1.00.

                                      -51-


            Section 10.6. Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Borrowers under this Agreement or any other
Loan Document is stayed upon the insolvency, bankruptcy or reorganization of any
of the Borrowers, all such amounts otherwise subject to acceleration under the
terms of this Agreement or the other Loan Documents shall nonetheless be payable
jointly and severally by the Guarantors hereunder forthwith on demand by the
Agent made at the request of the Required Lenders.

            Section 10.7. Benefit to Guarantors. All of the Guarantors are
engaged in related businesses and integrated to such an extent that the
financial strength and flexibility of each Guarantor has a direct impact on the
success of each other Guarantor. Each Guarantor will derive substantial direct
and indirect benefit from the extension of credit hereunder.

            Section 10.8. Guarantor Covenants. Each Guarantor shall take such
action as the Company is required by this Agreement to cause such Guarantor to
take, and shall refrain from taking such action as the Company is required by
this Agreement to prohibit such Guarantor from taking.


SECTION 11.              MISCELLANEOUS.

            Section 11.1. Withholding Taxes. (a) Payments Free of Withholding.
Except as otherwise required by law and subject to Section 11.1(b) hereof, each
payment by the Companies under this Agreement and under any other Loan Document
shall be made without withholding for or on account of any present or future
taxes (other than overall net income taxes on the recipient) imposed by or
within the jurisdiction in which the Company is domiciled, any jurisdiction from
which the Company makes any payment, or (in each case) any political subdivision
or taxing authority thereof or therein. If any such withholding is so required,
the Companies shall make the withholding, pay the amount withheld to the
appropriate governmental authority before penalties attach thereto or interest
accrues thereon and forthwith pay such additional amount as may be necessary to
ensure that the net amount actually received by each Lender and the Agent free
and clear of such taxes (including such taxes on such additional amount) is
equal to the amount which that Lender or the Agent (as the case may be) would
have received had such withholding not been made. If the Agent or any Lender
pays any amount in respect of any such taxes, penalties or interest, the
Companies shall reimburse the Agent or such Lender for that payment on demand in
the currency in which such payment was made. If any Company pays any such taxes,
penalties or interest, it shall deliver official tax receipts evidencing that
payment or certified copies thereof to the Lender or Agent on whose account such
withholding was made (with a copy to the Agent if not the recipient of the
original) on or before the thirtieth day after payment.

           (b) U.S. Withholding Tax Exemptions. Each Lender that is not a United
States person (as such term is defined in Section 7701(a)(30) of the Code) (a
"Non-U.S. Lender") represents and warrants to the Companies and the Guarantors
that as of the date such Person first becomes a Lender hereunder, payments made
hereunder to such Lender are exempt from withholding of United States federal
income taxes. Each Non-U.S. Lender agrees that such Lender shall submit to any
Company and the Agent on or before the earlier of the date the initial Borrowing


                                      -52-


is made hereunder and 30 days after the date hereof (or, if such Lender is an
assignee lender under Section 11.10 and was not previously a Lender hereunder,
within 30 days of first becoming a Lender), two duly completed and signed copies
of either Form 1001 (relating to such Lender and entitling it to a complete
exemption from withholding under the Code on all amounts to be received by such
Lender, including fees, pursuant to the Loan Documents and the Revolving Credit
Loans) or Form 4224 (relating to such Lender and entitling it to a complete
exemption from withholding under the Code on all amounts to be received by such
Lender, including fees, pursuant to the Loan Documents and the Revolving Credit
Loans) of the United States Internal Revenue Service. Thereafter and from time
to time, each Lender shall submit to the Company and the Agent such additional
duly completed and signed copies of one or the other of such Forms (or such
successor forms as shall be adopted from time to time by the relevant United
States taxing authorities) as may be (i) requested by the Company in a written
notice, directly or through the Agent, to such Lender and (ii) required under
then-current United States law or regulations to avoid or reduce United States
withholding taxes on payments in respect of all amounts to be received by such
Lender, including fees, pursuant to the Loan Documents or the Revolving Credit
Loans.

           (c) Inability of Bank to Submit Forms. If any Lender determines, as a
result of any change in applicable law, regulation or treaty, or in any official
application or interpretation thereof, that it is unable to submit to any
Company or the Agent any form or certificate that such Lender is obligated to
submit pursuant to subsection (b) of this Section 11.1 or that such Lender is
required to withdraw or cancel any such form or certificate previously submitted
or any such form or certificate otherwise becomes ineffective or inaccurate,
such Lender shall promptly notify any Company and Agent of such fact and the
Lender shall to that extent not be obligated to provide any such form or
certificate and will be entitled to withdraw or cancel any affected form or
certificate, as applicable. Notwithstanding the foregoing, the Borrowers shall
not be required to pay any additional amounts to the Agent or any Lender
pursuant to Section 11.1(a) hereof to the extent that the obligation to pay such
additional amounts would not have arisen but for a failure by the Agent or such
Lender to comply with the provisions of Section 11.1(b).

            Section 11.2. Non-Business Days. If any payment hereunder becomes
due and payable on a day which is not a Business Day, the due date of such
payment shall be extended to the next succeeding Business Day on which date such
payment shall be due and payable. In the case of any payment of principal
falling due on a day which is not a Business Day, interest on such principal
amount shall continue to accrue during such extension at the rate per annum then
in effect, which accrued amount shall be due and payable on the next scheduled
date for the payment of interest.

            Section 11.3. No Waiver, Cumulative Remedies. No delay or failure on
the part of any Lender or on the part of any holder of any of the Obligations in
the exercise of any power or right shall operate as a waiver thereof or as an
acquiescence in any default, nor shall any single or partial exercise of any
power or right preclude any other or further exercise thereof or the exercise of
any other power or right. The rights and remedies hereunder of the Lenders and
any of the holders of the Obligations are cumulative to, and not exclusive of,
any rights or remedies which any of them would otherwise have.

                                      -53-


            Section 11.4. Waivers, Modifications and Amendments. Any provision
hereof or of any of the other Loan Documents may be amended, modified, waived or
released and any Default or Event of Default and its consequences may be
rescinded and annulled upon the written consent of the Required Lenders;
provided, however, that without the consent of all Lenders no such amendment,
modification or waiver shall increase the amount or extend the term of any
Lender's Commitment or reduce the amount of any principal of or interest rate
applicable to, or extend the maturity of, any Obligation owed to it or reduce
the amount of the fees to which it is entitled hereunder or release any Guaranty
Agreement or waive any requirement hereunder for a Guaranty Agreement or change
this Section or change the definition of "Required Lenders" or change the number
of Lenders required to take any action hereunder or under any of the other Loan
Documents. No amendment, modification or waiver of the Agent's protective
provisions shall be effective without the prior written consent of the Agent.

            Section 11.5. Costs and Expenses. The Company agrees to pay on
demand the reasonable costs and expenses of the Agent in connection with the
negotiation, preparation, execution and delivery of this Agreement, the other
Loan Documents and the other instruments and documents to be delivered hereunder
or thereunder, and in connection with the transactions contemplated hereby or
thereby, and in connection with any consents hereunder or waivers or amendments
hereto or thereto, including the reasonable fees and expenses of Messrs. Chapman
and Cutler, counsel for the Agent, with respect to all of the foregoing (whether
or not the transactions contemplated hereby are consummated). The Companies
further agree to pay to Agent and the Lenders and any other holders of the
Obligations all reasonable costs and expenses (including court costs and
reasonable attorneys' fees), if any, incurred or paid by the Agent, the Lenders
or any other holders of the Obligations in connection with any Event of Default
or in connection with the enforcement of this Agreement or any of the other Loan
Documents or any other instrument or document delivered hereunder or thereunder.
The Companies further agree to indemnify and save the Lenders, the Agent and any
security trustee for the Lenders harmless from any and all liabilities, losses,
costs and expenses incurred by the Lenders or the Agent in connection with any
action, suit or proceeding brought against the Agent, or any security trustee or
any Lender by any Person (but excluding attorneys' fees for litigation solely
between the Lenders to which either Company is not a party) which arises out of
the transactions contemplated or financed hereby or out of any action or
inaction by the Agent, any security trustee or any Lender hereunder or
thereunder, except for such thereof as is caused by the gross negligence or
willful misconduct of the party seeking to be indemnified. The provisions of
this Section and the protective provisions of Section 2 hereof shall survive
payment of the Obligations.

            Section 11.6. Documentary Taxes. The Companies agree to pay on
demand any documentary, stamp or similar taxes payable in respect of this
Agreement or any other Loan Document, including interest and penalties, in the
event any such taxes are assessed, irrespective of when such assessment is made
and whether or not any credit is then in use or available hereunder.

                                      -54-


            Section 11.7. Survival of Representations. All representations and
warranties made herein or in any of the other Loan Documents or in certificates
given pursuant hereto or thereto shall survive the execution and delivery of
this Agreement and the other Loan Documents, and shall continue in full force
and effect with respect to the date as of which they were made as long as any
credit is in use or available hereunder.

            Section 11.8. Survival of Indemnities. All indemnities and other
provisions relative to reimbursement to the Agent and the Lenders of amounts
sufficient to protect the yield of the Agent and the Lenders with respect to the
Revolving Credit Loans and Letters of Credit, including, but not limited to,
Sections 1.3, 2.7, and 2.9 hereof, shall survive the termination of this
Agreement and the payment of the Obligations.

            Section 11.9. Participations. Any Lender may grant participations in
its extensions of credit hereunder to any other Lender or other lending
institution (a "Participant"), provided that (i) no Participant shall thereby
acquire any direct rights under this Agreement, (ii) no Lender shall agree with
a Participant not to exercise any of such Lender's rights hereunder without the
consent of such Participant except for rights which under the terms hereof may
only be exercised by all Lenders and (iii) no sale of a participation in
extensions of credit shall in any manner relieve the selling Lender of its
obligations hereunder.

           Section 11.10. Assignment Agreements. Each Lender may, from time to
time upon at least five Business Days' prior written notice to the Agent, assign
to other commercial lenders part of its rights and obligations under this
Agreement (including without limitation the indebtedness evidenced by the
Revolving Credit Notes then owned by such assigning Lender, together with an
equivalent proportion of its Commitments to make Revolving Credit Loans
hereunder) pursuant to written agreements executed by such assigning Lender,
such assignee lender or lenders, the Companies and the Agent, which agreements
shall specify in each instance the portion of the indebtedness evidenced by the
Revolving Credit Notes which is to be assigned to each such assignee lender and
the portion of the Percentage of the Commitments of the assigning Lender to be
assumed by it (the "Assignment Agreements"); provided, however, that (i) each
such assignment shall be of a constant, and not a varying, percentage of the
assigning Lender's rights and obligations under this Agreement and the
assignment shall cover the same percentage of such Lender's Percentage of the
Commitments, Revolving Credit Loans, Revolving Credit Notes and credit risk with
respect to Letters of Credit; (ii) unless the Agent otherwise consents, the
aggregate amount of the Commitments, Revolving Credit Loans, Revolving Credit
Notes and credit risk with respect to Letters of Credit of the assigning Lender
being assigned pursuant to each such assignment (determined as of the effective
date of the relevant Assignment Agreement) shall in no event be less than
$15,000,000 and shall be an integral multiple of $1,000,000; (iii) the Agent and
the Companies must each consent, which consent shall not be unreasonably
withheld, to each such assignment to a party which was not already a Lender
party to this Agreement; (iv) the assigning Lender must pay to the Agent a
processing and recordation fee of $2,500 and any out-of-pocket attorneys' fees
and expenses incurred by the Agent in connection with such Assignment Agreement
and (v) no assignment or delegation may be made if, at the time of and by reason
of such assignment and delegation, any Borrower would then be obligated to pay
any amount under Sections 1.3(e), 2.5, 2.6, 2.7, 2.8 or 11.1 hereof in excess of


                                      -55-


what it would have been required to pay thereunder had no such assignment been
made. Upon the execution of each Assignment Agreement by the assigning Lender
thereunder, the assignee lender thereunder, the Company and the Agent and
payment to such assigning Lender by such assignee lender of the purchase price
for the portion of the indebtedness of the Company being acquired by it, (i)
such assignee lender shall thereupon become a "Lender" for all purposes of this
Agreement with Commitments in the amounts set forth in such Assignment Agreement
and with all the rights, powers and obligations afforded a Lender hereunder,
(ii) such assigning Lender shall have no further liability for funding the
portion of its Commitments assumed by such other Lender and (iii) the address
for notices to such assignee Lender shall be as specified in the Assignment
Agreement executed by it. Concurrently with the execution and delivery of such
Assignment Agreement, the Borrowers shall execute and deliver Revolving Credit
Notes to the assignee Lender in the respective amounts of its Percentage of the
Commitments and, if necessary, new Revolving Credit Notes to the assigning
Lender in the respective amounts of its Percentage of the Commitments after
giving effect to the reduction occasioned by such assignment, all such Revolving
Credit Notes to constitute "Revolving Credit Notes" for all purposes of this
Agreement and of the other Loan Documents.

         Accepted and Agreed to at Chicago, Illinois as of the day and year last
above written.

         Each of the Lenders hereby agrees with each other Lender that if it
should receive or obtain any payment (whether by voluntary payment, by
realization upon collateral, by the exercise of rights of set-off or banker's
lien, by counterclaim or cross action, or by the enforcement of any rights under
this Agreement, any of the other Loan Documents or otherwise) in respect of the
Obligations in a greater amount than such Lender would have received had such
payment been made to the Agent and been distributed among the Lenders as
contemplated by Section 3.5 hereof then in that event the Lender receiving such
disproportionate payment shall purchase for cash without recourse from the other
Lenders an interest in the Obligations of the Companies to such Lenders in such
amount as shall result in a distribution of such payment as contemplated by
Section 3.5 hereof. In the event any payment made to a Lender and shared with
the other Lenders pursuant to the provisions hereof is ever recovered from such
Lender, the Lenders receiving a portion of such payment hereunder shall restore
the same to the payor Lender, but without interest.

disbursed, the status of each such loan from time to time as part of the



Domestic Rate Portion or a LIBOR Portion, and, in the case of any LIBOR Portion,
the interest rate and Interest Period applicable thereto.

         This Note is issued by the Borrowers under the terms and provisions of
