the date on which the Administrative Agent plans to complete the primary
syndication of the credit facility established hereunder. All borrowings,
conversions and repayments of Loans shall be effected so that each Bank will
have a pro rata share (according to its Percentage) of all types and Groups of
Loans.

         2.2.2    Borrowing Procedures. The Company shall give written notice or
telephonic notice (followed promptly by written confirmation thereof) to the
Administrative Agent of each proposed borrowing not later than (a) in the case
of a Floating Rate borrowing, 11:00 A.M., Chicago time, on the proposed date of
such borrowing, and (b) in the case of a Eurodollar borrowing, 9:00 A.M.,
Chicago time, at least two Business Days prior to the proposed date of such
borrowing. Each such notice shall be effective upon receipt by the
Administrative Agent, shall be irrevocable, and shall specify the date, amount
and type of borrowing and, in the case of a Eurodollar borrowing, the initial
Interest Period therefor. Promptly upon receipt of such notice, the
Administrative Agent shall advise each Bank thereof. Not later than 1:00 p.m.,
Chicago time, on the date of a proposed borrowing, each Bank shall provide the
Administrative Agent at the office specified by the Administrative Agent with
immediately available funds covering such Bank's Percentage of such borrowing
and, so long as the Administrative Agent has not received written notice that
the conditions precedent set forth in Section 11 with respect to such borrowing
have not been satisfied, the Administrative Agent shall pay over the requested
amount to the Company on the requested borrowing date. Each borrowing shall be
on a Business Day. Each borrowing shall be in an aggregate amount of at least
$500,000 and an integral multiple of $100,000.

         2.2.3    Conversion and Continuation Procedures. (a) Subject to the
provisions of Section 2.2.1, the Company may, upon irrevocable written notice to
the Administrative Agent in accordance with clause (b) below:

                           (i) elect, as of any Business Day, to convert any
                  outstanding Loan into a Loan of a different type; or

                                       14
<PAGE>   22

                           (ii) elect, as of the last day of the applicable
                  Interest Period, to continue any Group of Eurodollar Loans
                  having an Interest Period expiring on such day (or any part
                  thereof in an aggregate amount not less than $500,000 or a
                  higher integral multiple of $100,000) for a new Interest
                  Period.

                  (b) The Company shall give written or telephonic (followed
         promptly by written confirmation thereof) notice to the Administrative
         Agent of each proposed conversion or continuation not later than (i) in
         the case of conversion into Floating Rate Loans, 10:00 a.m., Chicago
         time, on the proposed date of such conversion; and (ii) in the case of
         a conversion into or continuation of Eurodollar Loans, 10:00 a.m.,
         Chicago time, at least three Business Days prior to the proposed date
         of such conversion or continuation, specifying in each case:

                           (1) the proposed date of conversion or continuation;

                           (2) the aggregate amount of Loans to be converted or
                  continued;

                           (3) the type of Loans resulting from the proposed
                  conversion or continuation; and

                           (4) in the case of conversion into, or continuation
                  of, Eurodollar Loans, the duration of the requested Interest
                  Period therefor.

                  (c) If upon expiration of any Interest Period applicable to
         Eurodollar Loans, the Company has failed to select timely a new
         Interest Period to be applicable to such Eurodollar Loans, the Company
         shall be deemed to have elected to convert such Eurodollar Loans into
         Floating Rate Loans effective on the last day of such Interest Period.

                  (d) The Administrative Agent will promptly notify each Bank of
         its receipt of a notice of conversion or continuation pursuant to this
         Section 2.4 or, if no timely notice is provided by the Company, of the
         details of any automatic conversion.

                  (e) Unless the Required Banks otherwise consent, during the
         existence of any Event of Default or Unmatured Event of Default, the
         Company may not elect to have a Floating Rate Loan converted into or
         continued as a Eurodollar Loan.

         2.3      Letter of Credit Procedures.

         2.3.1    L/C Applications. The Company shall give notice to the
Administrative Agent and the applicable Issuing Bank of the proposed issuance of
each Letter of Credit on a Business Day which is at least three Business Days
(or such lesser number of days as the Administrative Agent and such Issuing Bank
shall agree in any particular instance) prior to the proposed date of issuance
of such Letter

                                       15
<PAGE>   23
of Credit. Each such notice shall be accompanied by an L/C application, duly
executed by the Company (together with any Subsidiary for the account of which
the related Letter of Credit is to be issued) and in all respects satisfactory
to the Administrative Agent and the applicable Issuing Bank, together with such
other documentation as the Administrative Agent or such Issuing Bank may
reasonably request in support thereof, it being understood that each L/C
Application shall specify, among other things, the date on which the proposed
Letter of Credit is to be issued, the expiration date of such Letter of Credit
(which shall not be later than the Termination Date) and whether such Letter of
Credit is to be transferable in whole or in part. So long as the applicable
Issuing Bank has not received written notice that the conditions precedent set
forth in Section 11 with respect to the issuance of such Letter of Credit have
not been satisfied, such Issuing Bank shall issue such Letter of Credit on the
requested issuance date. Each Issuing Bank shall promptly advise the
Administrative Agent of the issuance of each Letter of Credit by such Issuing
Bank and of any amendment thereto, extension thereof or event or circumstance
changing the amount available for drawing thereunder.

         2.3.2    Participations in Letters of Credit. Concurrently with the
issuance of each Letter of Credit, the applicable Issuing Bank shall be deemed
to have sold and transferred to each other Bank, and each other Bank shall be
deemed irrevocably and unconditionally to have purchased and received from such
Issuing Bank, without recourse or warranty, an undivided interest and
participation, to the extent of such other Bank's Percentage, in such Letter of
Credit and the Company's reimbursement obligations with respect thereto. For the
purposes of this Agreement, the unparticipated portion of each Letter of Credit
shall be deemed to be the applicable Issuing Bank's "participation" therein.
Each Issuing Bank hereby agrees, upon request of the Administrative Agent or any
Bank, to deliver to such Bank a list of all outstanding Letters of Credit issued
by such Issuing Bank, together with such information related thereto as such
Bank may reasonably request.

         2.3.3    Reimbursement Obligations. The Company hereby unconditionally
and irrevocably agrees to reimburse the applicable Issuing Bank for each payment
or disbursement made by such Issuing Bank under any Letter of Credit honoring
any demand for payment made by the beneficiary thereunder, in each case on the
date that such payment or disbursement is made. Any amount not reimbursed on the
date of such payment or disbursement shall bear interest from the date of such
payment or disbursement to the date that such Issuing Bank is reimbursed by the
Company therefor, payable on demand, at a rate per annum equal to the Base Rate
from time to time in effect plus the Floating Rate Margin from time to time in
effect plus, beginning on the third Business Day after receipt of notice from
the Issuing Bank of such payment or disbursement, 2%. The applicable Issuing
Bank shall notify the Company and the Administrative Agent whenever any demand
for payment is made under any Letter of Credit by the beneficiary thereunder;
provided, however, that the failure of such Issuing Bank to so notify the
Company shall not affect the rights of such Issuing Bank or the Banks in any
manner whatsoever.

         2.3.4    Limitation on Obligations of Issuing Banks. In determining
whether to pay under any Letter of Credit, no Issuing Bank shall have any
obligation to the Company or any Bank other than to

                                       16
<PAGE>   24

confirm that any documents required to be delivered under such Letter of Credit
appear to have been delivered and appear to comply on their face with the
requirements of such Letter of Credit. Any action taken or omitted to be taken
by an Issuing Bank under or in connection with any Letter of Credit, if taken or
omitted in the absence of gross negligence and willful misconduct, shall not
impose upon such Issuing Bank any liability to the Company or any Bank and shall
not reduce or impair the Company's reimbursement obligations set forth in
Section 2.3.3 or the obligations of the Banks pursuant to Section 2.3.5.

         2.3.5    Funding by Banks to Issuing Banks. If an Issuing Bank makes
any payment or disbursement under any Letter of Credit and the Company has not
reimbursed such Issuing Bank in full for such payment or disbursement by 11:00
A.M., Chicago time, on the date of such payment or disbursement, or if any
reimbursement received by such Issuing Bank from the Company is or must be
returned or rescinded upon or during any bankruptcy or reorganization of the
Company or otherwise, each other Bank shall be obligated to pay to the
Administrative Agent for the account of such Issuing Bank, in full or partial
payment of the purchase price of its participation in such Letter of Credit, its
pro rata share (according to its Percentage) of such payment or disbursement
(but no such payment shall diminish the obligations of the Company under Section
2.3.3), and upon notice from the applicable Issuing Bank, the Administrative
Agent shall promptly notify each other Bank thereof. Each other Bank irrevocably
and unconditionally agrees to so pay to the Administrative Agent in immediately
available funds for the applicable Issuing Bank's account the amount of such
other Bank's Percentage of such payment or disbursement. If and to the extent
any Bank shall not have made such amount available to the Administrative Agent
by 2:00 P.M., Chicago time, on the Business Day on which such Bank receives
notice from the Administrative Agent of such payment or disbursement (it being
understood that any such notice received after noon, Chicago time, on any
Business Day shall be deemed to have been received on the next following
Business Day), such Bank agrees to pay interest on such amount to the
Administrative Agent for the applicable Issuing Bank's account forthwith on
demand for each day from the date such amount was to have been delivered to the
Administrative Agent to the date such amount is paid, at a rate per annum equal
to (a) for the first three days after demand, the Federal Funds Rate from time
to time in effect and (b) thereafter, the Base Rate from time to time in effect.
Any Bank's failure to make available to the Administrative Agent its Percentage
of any such payment or disbursement shall not relieve any other Bank of its
obligation hereunder to make available to the Administrative Agent such other
Bank's Percentage of such payment, but no Bank shall be responsible for the
failure of any other Bank to make available to the Administrative Agent such
other Bank's Percentage of any such payment or disbursement.

         2.4      Commitments Several. The failure of any Bank to make a
requested Loan on any date shall not relieve any other Bank of its obligation
(if any) to make a Loan on such date, but no Bank shall be responsible for the
failure of any other Bank to make any Loan to be made by such other Bank.

         2.5      Certain Conditions. Notwithstanding any other provision of
this Agreement, no Bank shall have an obligation to make any Loan, or to permit
the continuation of or any conversion into any

                                       17
<PAGE>   25

Eurodollar Loan, and no Issuing Bank shall have any obligation to issue any
Letter of Credit, if an Event of Default or Unmatured Event of Default exists.

         SECTION 3 NOTES EVIDENCING LOANS.

         3.1      Notes. The Loans of each Bank shall be evidenced by a
promissory note (each a "Note") payable to the order of such Bank substantially
in the form set forth in Exhibit A.

         3.2      Recordkeeping. Each Bank shall record in its records, or at
its option on the schedule attached to its Note, the date and amount of each
Loan made by such Bank, each repayment or conversion thereof and, in the case of
each Eurodollar Loan, the dates on which each Interest Period for such Loan
shall begin and end. The aggregate unpaid principal amount so recorded shall be
rebuttable presumptive evidence of the principal amount owing and unpaid on such
Note. The failure to so record any such amount or any error in so recording any
such amount shall not, however, limit or otherwise affect the obligations of the
Company hereunder or under any Note to repay the principal amount of the Loans
evidenced by such Note together with all interest accruing thereon.

         SECTION 4 INTEREST.

         4.1      Interest Rates. The Company promises to pay interest on the
unpaid principal amount of each Loan for the period commencing on the date of
such Loan until such Loan is paid in full as follows:

                  (a)      at all times while such Loan is a Floating Rate Loan,
         at a rate per annum equal to the sum of the Base Rate from time to time
         in effect plus the Floating Rate Margin from time to time in effect;
         and

                  (b)      at all times while such Loan is a Eurodollar Loan, at
         a rate per annum equal to the sum of the Eurodollar Rate (Reserve
         Adjusted) applicable to each Interest Period for such Loan plus the
         Eurodollar Margin from time to time in effect;

provided, however, that upon request of the Required Lenders at any time an
Event of Default exists, the interest rate applicable to each Loan shall be
increased by 2%.

         4.2      Interest Payment Dates. Accrued interest on each Floating Rate
Loan shall be payable in arrears on the last Business Day of each calendar month
and at maturity. Accrued interest on each Eurodollar Loan shall be payable on
the last day of each Interest Period relating to such Loan (and, in the case of
a Eurodollar Loan with a six-month Interest Period, on the three-month
anniversary of the first day of such Interest Period) and at maturity. After
maturity, accrued interest on all Loans shall be payable on demand.

                                       18
<PAGE>   26
         4.3      Setting and Notice of Eurodollar Rates. The applicable
Eurodollar Rate for each Interest Period shall be determined by the
Administrative Agent, and notice thereof shall be given by the Administrative
Agent promptly to the Company and each Bank. Each determination of the
applicable Eurodollar Rate by the Administrative Agent shall be conclusive and
binding upon the parties hereto, in the absence of demonstrable error. The
Administrative Agent shall, upon written request of the Company or any Bank,
deliver to the Company or such Bank a statement showing the computations used
by the Administrative Agent in determining any applicable Eurodollar Rate
hereunder.

         4.4      Computation of Interest. All determinations of interest for
Floating Rate Loans when the Base Rate is determined by the Prime Rate shall be
made on the basis of a year of 365 or 366 days, as the case may be, and the
actual number of days elapsed. All other computations of interest shall be
computed for the actual number of days elapsed on the basis of a year of 360
days. The applicable interest rate for each Floating Rate Loan shall change
simultaneously with each change in the Base Rate.

         SECTION 5 FEES.

         5.1      Non-Use Fee. The Company agrees to pay to the Administrative
Agent for the account of each Bank a non-use fee, for the period from the
Effective Date to the Termination Date, at 0.5% of the daily average of the
unused amount of such Bank's Percentage of the Commitment Amount. For purposes
of calculating usage under this Section, the Commitment Amount shall be deemed
used to the extent of the aggregate principal amount of all outstanding Loans
plus the Stated Amount of all Letters of Credit. Such non-use fee shall be
payable in arrears on the last Business Day of each calendar quarter and on the
Termination Date for any period then ending for which such non-use fee shall
not have theretofore been paid. The non-use fee shall be computed for the
actual number of days elapsed on the basis of a year of 360 days.

         5.2      Letter of Credit Fees. (a) The Company agrees to pay to the
Administrative Agent for the account of the Banks pro rata according to their
respective Percentages a letter of credit fee for each Letter of Credit in an
amount equal to the rate per annum in effect from time to time pursuant to
Schedule 1.1 of the undrawn amount of such Letter of Credit (computed for the
actual number of days elapsed on the basis of a year of 360 days); provided
that the rate applicable to each Letter of Credit shall be increased by 2% at
any time that an Event of Default exists. Such letter of credit fee shall be
payable in arrears on the last Business Day of each calendar quarter and on the
Termination Date for the period from the date of the issuance of each Letter of
Credit to the date such payment is due or, if earlier, the date on which such
Letter of Credit expired or was terminated.

         (b)      The Company agrees to pay each Issuing Bank a fronting fee
for each Letter of Credit issued by such Issuing Bank in the amount separately
agreed to between the Company and such Issuing Bank.

                                      19
<PAGE>   27

         (c)      In addition, with respect to each Letter of Credit, the
Company agrees to pay to the applicable Issuing Bank, for its own account, such
fees and expenses as such Issuing Bank customarily requires in connection with
the issuance, negotiation, processing and/or administration of letters of
credit in similar situations.

         5.3      Administrative Agent's and Arranger's Fees. The Company
agrees to pay to the Administrative Agent and the Arranger such administrative
agent's fees and arranger's fees, respectively, as are mutually agreed to from
time to time by the Company, the Administrative Agent and the Arranger.

         SECTION 6 CHANGES IN THE COMMITMENT AMOUNT; PREPAYMENTS.

         6.1      Changes in the Commitment Amount.

         6.1.1    Optional Increase in the Commitment Amount. The Company may,
from time to time after the Equity Offering and a "Successful Syndication" (as
defined in the letter agreement dated February 11, 2000 between the Company and
the Administrative Agent) have been completed, by means of a letter to the
Administrative Agent substantially in the form of Exhibit I, request that the
Commitment Amount be increased by (a) increasing the Commitment of one or more
Banks which have agreed to such increase and/or (b) adding one or more
commercial banks or other Persons as a party hereto with a Commitment in an
amount agreed to by any such commercial bank or other Person; provided that (i)
no commercial bank or other Person shall be added as a party hereto without the
written consent of the Administrative Agent (which shall not be unreasonably
withheld) and (ii) in no event shall the Commitment Amount exceed $80,000,000
without the written consent of all Banks. Any increase in the Commitment Amount
pursuant to this Section 6.1.1 shall be effective three Business Days after the
date on which the Administrative Agent has received and accepted the applicable
increase letter in the form of Annex 1 to Exhibit I (in the case of an increase
in the Commitment of an existing Bank) or assumption letter in the form of
Annex 2 to Exhibit I (in the case of the addition of a commercial bank or other
Person as a new Bank). The Administrative Agent shall promptly notify the
Company and the Banks of any increase in the Commitment Amount pursuant to this
Section 6.1.1 and of the Commitment and Percentage of each Bank after giving
effect thereto. The Company acknowledges that, in order to maintain Loans in
accordance with each Bank's Percentage, a reallocation of the Commitments as a
result of a non-pro-rata increase in the Commitment Amount may require
prepayment of all or portions of certain Loans on the date of such increase
(and any such prepayment shall be subject to the provisions of Section 8.4).

         6.1.2    Voluntary Reductions of the Commitment Amount. The Company
may from time to time on at least five Business Days' prior written notice
received by the Agent (which shall promptly advise each Bank thereof)
permanently reduce the Commitment Amount to an amount not less than the Total
Outstandings. Any such reduction shall be in an amount not less than $5,000,000
or a higher integral multiple of $1,000,000. The Company may at any time on
like notice terminate the

                                      20
<PAGE>   28

Commitments upon payment in full of all Loans and all other obligations of the
Company hereunder and cash collateralization in full, pursuant to documentation
in form and substance reasonably satisfactory to the Administrative Agent, of
all obligations arising with respect to Letters of Credit. All reductions of
the Commitment Amount shall reduce the amounts of the Commitments of the Banks
pro rata according to their respective Percentages.

         6.2      Prepayments. The Company may from time to time prepay the
Loans in whole or in part, provided that the Company shall give the
Administrative Agent (which shall promptly advise each Bank) notice thereof not
later than 10:00 A.M., Chicago time, on the day of such prepayment (which shall
be a Business Day), specifying the Loans to be prepaid and the date and amount
of prepayment. Each partial prepayment shall be in a principal amount of
$100,000 or a higher integral multiple thereof. All prepayments shall be
applied to prepay the Loans of the Banks pro rata according to their respective
Percentages. Any prepayment of a Eurodollar Loan on a day other than the last
day of an Interest Period therefor shall include interest on the principal
amount being repaid and shall be subject to Section 8.4.

         SECTION 7 MAKING AND PRORATION OF PAYMENTS; SETOFF; TAXES.

         7.1      Making of Payments. All payments of principal of or interest
on the Notes, and of all fees, shall be made by the Company to the
Administrative Agent in immediately available funds at the office specified by
the Administrative Agent not later than noon, Chicago time, on the date due;
and funds received after that hour shall be deemed to have been received by the
Administrative Agent on the next following Business Day. The Administrative
Agent shall promptly remit to each Bank its share of all such payments received
in collected funds by the Administrative Agent for the account of such Bank.

        All payments under Section 8.1 shall be made by the Company directly to
the Bank entitled thereto.

         7.2      Application of Certain Payments. Each payment of principal
shall be applied to such Loans as the Company shall direct by notice to be
received by the Administrative Agent on or before the date of such payment or,
in the absence of such notice, as the Administrative Agent shall determine in
its discretion. Concurrently with each remittance to any Bank of its share of
any such payment, the Administrative Agent shall advise such Bank as to the
application of such payment.

         7.3      Due Date Extension. If any payment of principal or interest
with respect to any of the Notes, or of any fees, falls due on a day which is
not a Business Day, then such due date shall be extended to the immediately
following Business Day (unless, in the case of a Eurodollar Loan, such
immediately following Business Day is the first Business Day of a calendar
month, in which case such date shall be the immediately preceding Business Day)
and, in the case of principal, additional interest shall accrue and be payable
for the period of any such extension.

                                      21
<PAGE>   29

         7.4      Setoff. The Company agrees that the Administrative Agent and
each Bank have all rights of set-off and bankers' lien provided by applicable
law, and in addition thereto, the Company agrees that at any time any Event of
Default exists, the Administrative Agent and each Bank may apply to the payment
of any obligations of the Company hereunder, whether or not then due, any and
all balances, credits, deposits, accounts or moneys of the Company then or
thereafter with the Administrative Agent or such Bank.

         7.5      Proration of Payments. If any Bank shall obtain any payment
or other recovery (whether voluntary, involuntary, by application of offset or
otherwise, but excluding any payment pursuant to Section 8.7 or 14.9) on
account of principal of or interest on any Note (or on account of its
participation in any Letter of Credit) in excess of its pro rata share of
payments and other recoveries obtained by all Banks on account of principal of
and interest on Notes (or such participation) then held by them, such Bank
shall purchase from the other Banks such participation in the Notes (or sub-
participation in Letters of Credit) held by them as shall be necessary to cause
such purchasing Bank to share the excess payment or other recovery ratably with
each of them; provided, however, that if all or any portion of the excess
payment or other recovery is thereafter recovered from such purchasing Bank,
the purchase shall be rescinded and the purchase price restored to the extent
of such recovery.

         7.6      Taxes. (a) All payments of principal of, and interest on, the
Loans and all other amounts payable hereunder shall be made free and clear of
and without deduction for any present or future income, excise, stamp or
franchise taxes and other taxes, fees, duties, withholdings or other charges of
any nature whatsoever imposed by any taxing authority, but excluding franchise
taxes and taxes imposed on or measured by any Bank's net income or receipts
(all non-excluded items being called "Taxes"). If any withholding or deduction
from any payment to be made by the Company hereunder is required in respect of
any Taxes pursuant to any applicable law, rule or regulation, then the Company
will:

                  (i)      pay directly to the relevant authority the full
         amount required to be so withheld or deducted;

                  (ii)     promptly forward to the Administrative Agent an
         official receipt or other documentation satisfactory to the
         Administrative Agent evidencing such payment to such authority; and

                  (iii)    (except to the extent such withholding or deduction
         would not be required if such Bank's Exemption Representation were
         true) pay to the Administrative Agent for the account of the Banks
         such additional amount or amounts as is necessary to ensure that the
         net amount actually received by each Bank will equal the full amount
         such Bank would have received had no such withholding or deduction
         been required.

                                      22
<PAGE>   30

Moreover, if any Taxes are directly asserted against the Administrative Agent
or any Bank with respect to any payment received by the Administrative Agent or
such Bank hereunder, the Administrative Agent or such Bank may pay such Taxes
and the Company will (except to the extent such Taxes are payable by a Bank and
would not have been payable if such Bank's Exemption Representation were true)
promptly pay such additional amounts (including any penalty, interest and
expense) as is necessary in order that the net amount received by such Person
after the payment of such Taxes (including any Taxes on such additional amount)
shall equal the amount such Person would have received had such Taxes not been
asserted.

         (b)      If the Company fails to pay any Taxes when due to the
appropriate taxing authority or fails to remit to the Administrative Agent, for
the account of the respective Banks, the required receipts or other required
documentary evidence, the Company shall indemnify the Banks for any incremental
Taxes, interest or penalties that may become payable by any Bank as a result of
any such failure. For purposes of this Section 7.6, a distribution hereunder by
the Administrative Agent or any Bank to or for the account of any Bank shall be
deemed a payment by the Company.

         (c)      Each Bank represents and warrants (such Bank's "Exemption
Representation") to the Company and the Administrative Agent that, as of the
date of this Agreement (or, in the case of an Assignee, the date it becomes a
party hereto), it is entitled to receive payments hereunder without any
deduction or withholding for or on account of any Taxes imposed by the United
States of America or any political subdivision or taxing authority thereof.

         (d)      Upon the request from time to time of the Company or the
Administrative Agent, each Bank that is organized under the laws of a
jurisdiction other than the United States of America shall execute and deliver
to the Company and the Administrative Agent one or more (as the Company or the
Administrative Agent may reasonably request) United States Internal Revenue
Service Forms 4224 or Forms 1001 or such other forms or documents,
appropriately completed, as may be applicable to establish the extent, if any,
to which a payment to such Bank is exempt from withholding or deduction of
Taxes.

         (e)      If, and to the extent that, any Bank shall obtain a credit,
relief or remission for, or repayment of, any Taxes indemnified or paid by the
Company pursuant to this Section 7.6, such Bank agrees to promptly notify the
Company thereof and thereupon enter into negotiations in good faith with the
Company to determine the basis on which an equitable reimbursement of such
Taxes can be made to the Company.

         8 INCREASED COSTS; SPECIAL PROVISIONS FOR EURODOLLAR LOANS.

         8.1      Increased Costs. (a) If, after the date hereof, the adoption
of any applicable law, rule or regulation, or any change therein, or any change
in the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or

                                      23
<PAGE>   31

administration thereof, or compliance by any Bank (or any Eurodollar Office of
such Bank) with any request or directive (whether or not having the force of
law) of any such authority, central bank or comparable agency

                  (A)      shall subject any Bank (or any Eurodollar Office of
         such Bank) to any tax, duty or other charge with respect to its
         Eurodollar Loans, its Note or its obligation to make Eurodollar Loans,
         or shall change the basis of taxation of payments to any Bank of the
         principal of or interest on its Eurodollar Loans or any other amounts
         due under this Agreement in respect of its Eurodollar Loans or its
         obligation to make Eurodollar Loans (except for changes in the rate of
         tax on the overall net income of such Bank or its Eurodollar Office
         imposed by the jurisdiction in which such Bank's principal executive
         office or Eurodollar Office is located); or

                  (B)      shall impose, modify or deem applicable any reserve
         (including any reserve imposed by the Board of Governors of the
         Federal Reserve System, but excluding any reserve included in the
         determination of interest rates pursuant to Section 4), special
         deposit or similar requirement against assets of, deposits with or for
         the account of, or credit extended by any Bank (or any Eurodollar
         Office of such Bank); or

                  (C)      shall impose on any Bank (or its Eurodollar Office)
         any other condition affecting its Eurodollar Loans, its Note or its
         obligation to make Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to (or in the
case of Regulation D of the Board of Governors of the Federal Reserve System,
to impose a cost on) such Bank (or any Eurodollar Office of such Bank) of
making or maintaining any Eurodollar Loan, or to reduce the amount of any sum
received or receivable by such Bank (or its Eurodollar Office) under this
Agreement or under its Note with respect thereto, then within 10 days after
demand by such Bank (which demand shall be accompanied by a statement setting
forth the basis for such demand and a calculation of the amount thereof in
reasonable detail, a copy of which shall be furnished to the Administrative
Agent), the Company shall pay directly to such Bank such additional amount as
will compensate such Bank for such increased cost or such reduction.

         (b)      If any Bank shall reasonably determine that the adoption or
phase-in of any applicable law, rule or regulation regarding capital adequacy,
or any change therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance by any
Bank or any Person controlling such Bank 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 Bank's or such controlling Person's capital
as a consequence of such Bank's obligations hereunder or under any Letter of
Credit to a level below that which such Bank or such controlling Person could
have achieved but for such adoption, change or compliance (taking into
consideration such Bank's or such controlling Person's policies with respect to

                                      24
<PAGE>   32

capital adequacy) by an amount deemed by such Bank or such controlling Person
to be material, then from time to time, within 10 days after demand by such
Bank (which demand shall be accompanied by a statement setting forth the basis
for such demand and a calculation of the amount thereof in reasonable detail, a
copy of which shall be furnished to the Administrative Agent), the Company
shall pay to such Bank such additional amount or amounts as will compensate
such Bank or such controlling Person for such reduction.

         (c)      Notwithstanding the foregoing provisions of this Section 8.1,
(i) if any Bank fails to notify the Company of any event or circumstance which
will entitle the Bank to compensation pursuant to this Section 8.1 within 120
days after such Bank obtains knowledge of such event or circumstance, then such
Bank shall not be entitled to compensation from the Company for any amount
arising prior to the date which is 120 days before the date on which such Bank
notifies the Company of such event or circumstance; and (ii) no Bank shall not
make a claim for compensation under this Section 8.1 unless such Bank is then
making a claim against a substantial portion of the other borrowers from such
Bank which have language in the applicable borrowing agreement similar to that
found in the foregoing provisions of this Section 8.1.

         8.2      Basis for Determining Interest Rate Inadequate or Unfair. If
with respect to any Interest Period:

                  (a)      deposits in Dollars (in the applicable amounts) are
         not being offered to the Administrative Agent in the interbank
         eurodollar market for such Interest Period, or the Administrative
         Agent otherwise reasonably determines (which determination, if made in
         good faith, shall be binding and conclusive on the Company) that by
         reason of circumstances affecting the interbank eurodollar market
         adequate and reasonable means do not exist for ascertaining the
         applicable Eurodollar Rate; or

                  (b)      Banks having an aggregate Percentage of 40% or more
         advise the Administrative Agent that the Eurodollar Rate (Reserve
         Adjusted) as determined by the Administrative Agent will not
         adequately and fairly reflect the cost to such Banks of maintaining or
         funding such Eurodollar Loans for such Interest Period (taking into
         account any amount to which such Banks may be entitled under Section
         8.1) or that the making or funding of Eurodollar Loans has become
         impracticable as a result of an event occurring after the date of this
         Agreement which in the opinion of such Banks materially affects such
         Loans;

then the Administrative Agent shall promptly notify the other parties thereof
and, so long as such circumstances shall continue, (i) no Bank shall be under
any obligation to make or convert into Eurodollar Loans and (ii) on the last
day of the current Interest Period for each Eurodollar Loan, such Loan shall,
unless then repaid in full, automatically convert to a Floating Rate Loan.

                                      25
<PAGE>   33

         8.3      Changes in Law Rendering Eurodollar Loans Unlawful. In the
event that any change in (including the adoption of any new) applicable laws or
regulations, or any change in the interpretation of applicable laws or
regulations by any governmental or other regulatory body charged with the
administration thereof, should make it (or in the good faith judgment of any
Bank cause a substantial question as to whether it is) unlawful for any Bank to
make, maintain or fund Eurodollar Loans, then such Bank shall promptly notify
each of the other parties hereto and, so long as such circumstances shall
continue, (a) such Bank shall have no obligation to make or convert into
Eurodollar Loans (but shall make Floating Rate Loans concurrently with the
making of or conversion into Eurodollar Loans by the Banks which are not so
affected, in each case in an amount equal to such Bank's pro rata share of all
Eurodollar Loans which would be made or converted into at such time in the
absence of such circumstances) and (b) on the last day of the current Interest
Period for each Eurodollar Loan of such Bank (or, in any event, on such earlier
date as may be required by the relevant law, regulation or interpretation),
such Eurodollar Loan shall, unless then repaid in full, automatically convert
to a Floating Rate Loan. Each Floating Rate Loan made by a Bank which, but for
the circumstances described in the foregoing sentence, would be a Eurodollar
Loan (an "Affected Loan") shall remain outstanding for the same period as the
Group of Eurodollar Loans of which such Affected Loan would be a part absent
such circumstances.

         8.4      Funding Losses. The Company hereby agrees that upon demand by
any Bank (which demand shall be accompanied by a statement setting forth the
basis for the amount being claimed, a copy of which shall be furnished to the
Administrative Agent), the Company will indemnify such Bank against any net
loss or expense which such Bank may sustain or incur (including any net loss or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Bank to fund or maintain any Eurodollar Loan), as
reasonably determined by such Bank, as a result of (a) any payment, prepayment
or conversion of any Eurodollar Loan of such Bank on a date other than the last
day of an Interest Period for such Loan (including any conversion pursuant to
Section 8.3) or (b) any failure of the Company to borrow or convert any Loan on
a date specified therefor in a notice of borrowing or conversion pursuant to
this Agreement. For this purpose, all notices to the Administrative Agent
pursuant to this Agreement shall be deemed to be irrevocable.

         8.5      Right of Banks to Fund through Other Offices. Each Bank may,
if it so elects, fulfill its commitment as to any Eurodollar Loan by causing a
foreign branch or affiliate of such Bank to make such Loan, provided that in
such event for the purposes of this Agreement such Loan shall be deemed to have
been made by such Bank and the obligation of the Company to repay such Loan
shall nevertheless be to such Bank and shall be deemed held by it, to the
extent of such Loan, for the account of such branch or affiliate.

         8.6      Discretion of Banks as to Manner of Funding. Notwithstanding
any provision of this Agreement to the contrary, each Bank shall be entitled to
fund and maintain its funding of all or any part of its Loans in any manner it
sees fit, it being understood, however, that for the purposes of this Agreement
all determinations hereunder shall be made as if such Bank had actually funded
and

                                      26
<PAGE>   34

maintained each Eurodollar Loan during each Interest Period for such Loan
through the purchase of deposits having a maturity corresponding to such
Interest Period and bearing an interest rate equal to the Eurodollar Rate for
such Interest Period.

         8.7      Mitigation of Circumstances; Replacement of Affected Bank.
(a) Each Bank shall promptly notify the Company and the Administrative Agent of
any event of which it has knowledge which will result in, and will use
reasonable commercial efforts available to it (and not, in such Bank's good
faith judgment, otherwise disadvantageous to such Bank) to mitigate or avoid,
(i) any obligation by the Company to pay any amount pursuant to Section 7.6 or
8.1 or (ii) the occurrence of any circumstances of the nature described in
Section 8.2 or 8.3 (and, if any Bank has given notice of any such event
described in clause (i) or (ii) above and thereafter such event ceases to
exist, such Bank shall promptly so notify the Company and the Administrative
Agent). Without limiting the foregoing, each Bank will designate a different
funding office if such designation will avoid (or reduce the cost to the
Company of) any event described in clause (i) or (ii) of the preceding sentence
and such designation will not, in such Bank's sole good faith judgment, be
otherwise disadvantageous to such Bank.

         (b)      At any time any Bank is an Affected Bank, the Company may
replace such Affected Bank as a party to this Agreement with one or more other
bank(s) or financial institution(s) reasonably satisfactory to the
Administrative Agent (and upon notice from the Company such Affected Bank shall
assign pursuant to an Assignment Agreement, and without recourse or warranty,
its Commitment, its Loans, its Note, its participation in Letters of Credit,
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, its ratable share of all accrued and unpaid fees, any amounts
payable under Section 8.4 as a result of such Bank receiving payment of any
Eurodollar Loan prior to the end of an Interest Period therefor and all other
obligations owed to such Affected Bank hereunder).

         8.8      Conclusiveness of Statements; Survival of Provisions.
Determinations and statements of any Bank pursuant to Section 8.1, 8.2, 8.3 or
8.4 shall be conclusive absent demonstrable error. Banks may use reasonable
averaging and attribution methods in determining compensation under Sections
8.1 and 8.4, and the provisions of such Sections shall survive repayment of the
Loans, cancellation of the Notes, cancellation or expiration of the Letters of
Credit and any termination of this Agreement.

         SECTION 9 WARRANTIES.

         To induce the Administrative Agent and the Banks to enter into this
Agreement and to induce the Banks to make Loans and issue or purchase

Company of this Agreement and each other Loan Document to which it is a party,

         9.3      Validity and Binding Nature. Each of this Agreement and each
other Loan Document to which the Company is a party is the legal, valid and
binding obligation of the Company, enforceable against the Company in
accordance with its terms, subject to bankruptcy, insolvency and similar laws
affecting the enforceability of creditors' rights generally and to general
principles of equity; and each Loan Document to which any Subsidiary is a party

the Company or such Subsidiary, it is consented to or acquiesced in by the
Company or such Subsidiary, or remains for 60 days undismissed; or the Company

hereunder shall become immediately due and payable and the Company shall become
immediately obligated to deliver to the Administrative Agent cash collateral in
an amount equal to the outstanding face amount of all Letters of Credit, all
without presentment, demand, protest or notice of any kind; and, if any other
Event of Default shall occur and be continuing, the Administrative Agent (upon
written request of the Required Banks) shall declare the Commitments (if they
have not theretofore terminated) to be terminated and/or declare all Notes and
all other obligations hereunder to be due and payable and/or demand that the
Company immediately deliver to the Administrative Agent cash collateral in
amount equal to the outstanding face amount of all Letters of Credit, whereupon
the Commitments (if they have not theretofore terminated) shall immediately
terminate and/or all Notes and all other obligations hereunder shall become
immediately due and payable and/or the Company shall immediately become
obligated to deliver to the Administrative Agent cash collateral in an amount
equal to the face amount of all Letters of Credit, all without presentment,
demand, protest or notice of any kind. The Administrative Agent shall promptly
advise the Company of any such declaration, but failure to do so shall not
impair the effect of such declaration. Notwithstanding the foregoing, the effect
as an Event of Default of any event described in Section 12.1.1 or Section
12.1.4 may be waived by the written concurrence of all of the Banks, and the
effect as an Event of Default of any other event described in this Section 12
may be waived by the written concurrence of the Required Banks. Any cash
collateral delivered hereunder shall be held by the Administrative Agent
(without liability for interest thereon) and applied to obligations arising in
connection with any drawing under a Letter of Credit. After the expiration or
termination of all Letters of Credit, such cash collateral shall be applied by
the Administrative Agent to any remaining obligations hereunder and any excess
shall be delivered to the Company or as a court of competent jurisdiction may
elect.

therewith. Each Issuing Bank shall have all of the benefits and immunities (i)
provided to the Administrative Agent in this Section 13 with respect to any acts
taken or omissions suffered by such Issuing Bank in connection with Letters of
Credit issued by it or proposed to be issued by it and the applications and
agreements for letters of credit pertaining to such Letters of Credit as fully
as if the term "Administrative Agent", as used in this Section 13, included such
Issuing Bank with respect to such acts or omissions and (ii) as additionally
provided in this Agreement with respect to the Issuing Banks.

         13.2     Delegation of Duties. The Administrative Agent may execute any
of its duties under this Agreement or any other Loan Document by or through
agents, employees or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. The Administrative
Agent shall not be responsible for the negligence or misconduct of any agent or
attorney-in-fact that it selects with reasonable care.

         13.3     Liability of Administrative Agent. None of the Agent-Related
Persons shall (i) be liable for any action taken or omitted to be taken by any
of them under or in connection with this Agreement or any other Loan Document or
the transactions contemplated hereby (except for its own gross negligence or
willful misconduct), or (ii) be responsible in any manner to any of the Banks
for any recital, statement, representation or warranty made by the Company or
any Subsidiary or Affiliate of the Company, or any officer thereof, contained in
this Agreement or in any other Loan Document, or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, this Agreement or any other
Loan Document, or the validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document, or for any failure of
the Company or any other party to any Loan Document to perform its obligations
hereunder or thereunder. No Agent-Related Person shall be under any obligation
to any Bank to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any
other Loan Document, or to inspect the properties, books or records of the
Company or any of the Company's Subsidiaries or Affiliates.

         13.4     Reliance by Administrative Agent. The Administrative Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
writing, resolution, notice, consent, certificate, affidavit, letter, telegram,
facsimile, telex or telephone message, statement or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons, and upon advice and statements of
legal counsel (including counsel to the Company), independent accountants and
other experts selected by the Administrative Agent. The Administrative Agent
shall be fully justified in failing or refusing to take any action under this
Agreement or any other Loan Document unless it shall first receive such advice
or concurrence of the Required Banks as it

                                       49
<PAGE>   57

deems appropriate and, if it so requests, confirmation from the Banks of their
obligation to indemnify the Administrative Agent against any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take any such action. The Administrative Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement or any
other Loan Document in accordance with a request or consent of the Required
Banks and such request and any action taken or failure to act pursuant thereto
shall be binding upon all of the Banks.

         13.5     Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Event of Default or
Unmatured Event of Default except with respect to defaults in the payment of
principal, interest and fees required to be paid to the Administrative Agent for
the account of the Banks, unless the Administrative Agent shall have received
written notice from a Bank or the Company referring to this Agreement,
describing such Event of Default or Unmatured Event of Default and stating that
such notice is a "notice of default". The Administrative Agent will notify the
Banks of its receipt of any such notice. The Administrative Agent shall take
such action with respect to such Event of Default or Unmatured Event of Default
as may be requested by the Required Banks in accordance with Section 12;
provided, however, that unless and until the Administrative Agent has received
any such request, the Administrative Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such Event
of Default or Unmatured Event of Default as it shall deem advisable or in the
best interest of the Banks.

         13.6     Credit Decision. Each Bank acknowledges that none of the
Agent-Related Persons has made any representation or warranty to it, and that no
act by the Administrative Agent hereafter taken, including any review of the
affairs of the Company and its Subsidiaries, shall be deemed to constitute any
representation or warranty by any Agent-Related Person to any Bank. Each Bank
represents to the Administrative Agent that it has, independently and without
reliance upon any Agent-Related Person and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, prospects, operations, property, financial and
other condition and creditworthiness of the Company and its Subsidiaries, and
all applicable bank regulatory laws relating to the transactions contemplated
hereby, and made its own decision to enter into this Agreement and to extend
credit to the Company hereunder. Each Bank also represents that it will,
independently and without reliance upon any Agent-Related Person and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Company. Except for notices, reports and other documents
expressly herein required to be furnished to the Banks by the Administrative
Agent, the Administrative Agent shall not have any duty or responsibility to
provide any Bank with any credit or other information concerning the business,
prospects, operations, property, financial or other condition or
creditworthiness of the Company which may come into the possession of any of the
Agent-Related Persons.

                                       50
<PAGE>   58

         13.7     Indemnification. Whether or not the transactions contemplated
hereby are consummated, the Banks shall indemnify upon demand the Agent-Related
Persons (to the extent not reimbursed by or on behalf of the Company and without
limiting the obligation of the Company to do so), pro rata, from and against any
and all Indemnified Liabilities; provided, however, that no Bank shall be liable
for any payment to the Agent-Related Person of any portion of the Indemnified
Liabilities resulting solely from such Person's gross negligence or willful
misconduct. Without limitation of the foregoing, each Bank shall reimburse the
Administrative Agent upon demand for its ratable share of any costs or
out-of-pocket expenses (including reasonable fees of attorneys for the
Administrative Agent (including the allocable costs of internal legal services
and all disbursements of internal counsel)) incurred by the Administrative Agent
in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that the Administrative
Agent is not reimbursed for such expenses by or on behalf of the Company. The
undertaking in this Section shall survive repayment of the Loans, cancellation
of the Notes, cancellation or expiration of the Letters of Credit, any
foreclosure under, or any modification, release or discharge of, any or all of
the Collateral Documents, any termination of this Agreement and the resignation
or replacement of the Administrative Agent.

         For the purposes of this Section 13.7, "Indemnified Liabilities" shall
mean: any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, charges, expenses and disbursements (including
reasonable fees of attorneys for the Administrative Agent (including the
allocable costs of internal legal services and all disbursements of internal
counsel)) of any kind or nature whatsoever which may at any time (including at
any time following repayment of the Loans and the termination, resignation or
replacement of the Administrative Agent or the replacement of any Bank) be
imposed on, incurred by or asserted against any Agent-Related Person in any way
relating to or arising out of this Agreement or any document contemplated by or
referred to herein, or the transactions contemplated hereby, or any action taken
or omitted by any such Person under or in connection with any of the foregoing,
including with respect to any investigation, litigation or proceeding (including
(a) any case, action or proceeding before any court or other governmental
authority relating to bankruptcy, reorganization, insolvency, liquidation,
receivership, dissolution, winding-up or relief of debtors, or (b) any general
assignment for the benefit of creditors, composition, marshalling of assets for
creditors, or other, similar arrangement in respect of its creditors generally
or any substantial portion of its creditors; undertaken under U.S. Federal,
state or foreign law, including the Bankruptcy Code, and including any appellate
proceeding) related to or arising out of this Agreement or the Commitments or
the use of the proceeds thereof, whether or not any Agent-Related Person, any
Bank or any of their respective officers, directors, employees, counsel, agents
or attorneys-in-fact is a party thereto.

         13.8     Administrative Agent in Individual Capacity. Bank of America
and its Affiliates may make loans to, issue letters of credit for the account
of, accept deposits from, acquire equity interests in and generally engage in
any kind of banking, trust, financial advisory, underwriting or other business

                                       51
<PAGE>   59

with the Company and its Subsidiaries and Affiliates as though Bank of America
were not the Administrative Agent, the Issuing Bank hereunder and without notice
to or consent of the Banks. The Banks acknowledge that, pursuant to such
activities, Bank of America or its Affiliates may receive information regarding
the Company or its Affiliates (including information that may be subject to
confidentiality obligations in favor of the Company or such Subsidiary) and
acknowledge that the Administrative Agent shall be under no obligation to
provide such information to them. With respect to their Loans, Bank of America
and its Affiliates shall have the same rights and powers under this Agreement as
any other Bank and may exercise the same as though Bank of America were not the
Administrative Agent and the Issuing Bank, and the terms "Bank" and "Banks"
include Bank of America and its Affiliates, to the extent applicable, in their
individual capacities.

         13.9     Successor Administrative Agent. The Administrative Agent may,
and at the request of the Required Banks shall, resign as Administrative Agent
upon 30 days' notice to the Banks. If the Administrative Agent resigns under
this Agreement, the Required Banks shall, with (so long as no Event of Default
exists) the consent of the Company (which shall not be unreasonably withheld or
delayed), appoint from among the Banks a successor administrative agent for the
Banks. If no successor administrative agent is appointed prior to the effective
date of the resignation of the Administrative Agent, the Administrative Agent
may appoint, after consulting with the Banks and the Company, a successor
administrative agent from among the Banks. Upon the acceptance of its
appointment as successor administrative agent hereunder, such successor
administrative agent shall succeed to all the rights, powers and duties of the
retiring Administrative Agent and the term "Administrative Agent" shall mean
such successor administrative agent, and the retiring Administrative Agent's
appointment, powers and duties as Administrative Agent shall be terminated.
After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this Section 13 and Sections 14.6 and
14.13 shall inure to its benefit as to any actions taken or omitted to be taken
by it while it was Administrative Agent under this Agreement. If no successor
administrative agent has accepted appointment as Administrative Agent by the
date which is 30 days following a retiring Administrative Agent's notice of
resignation, the retiring Administrative Agent's resignation shall nevertheless
thereupon become effective and the Banks shall perform all of the duties of the
Administrative Agent hereunder until such time, if any, as the Required Banks
appoint a successor administrative agent as provided for above. Notwithstanding
the foregoing, however, Bank of America may not be removed as the Administrative
Agent at the request of the Required Banks unless Bank of America shall also
simultaneously be replaced as an "Issuing Bank" hereunder pursuant to
documentation in form and substance reasonably satisfactory to Bank of America.

         13.10    Withholding Tax.

                  (a)      If any Bank is a "foreign corporation, partnership or
         trust" within the meaning of the Code and such Bank claims exemption
         from, or a reduction of, U.S. withholding tax under Sections 1441 or
         1442 of the Code, such Bank agrees to deliver to the Administrative
         Agent:

                                       52
<PAGE>   60

                           (i) if such Bank claims an exemption from, or a
                  reduction of, withholding tax under a United States tax
                  treaty, properly completed Internal Revenue Service ("IRS")
                  Forms 1001 and W-8 before the payment of any interest in the
                  first calendar year and before the payment of any interest in
                  each third succeeding calendar year during which interest may
                  be paid under this Agreement;

                           (ii) if such Bank claims that interest paid under
                  this Agreement is exempt from United States withholding tax
                  because it is effectively connected with a United States trade
                  or business of such Bank, two properly completed and executed
                  copies of IRS Form 4224 before the payment of any interest is
                  due in the first taxable year of such Bank and in each
                  succeeding taxable year of such Bank during which interest may
                  be paid under this Agreement, and IRS Form W-9; and

                           (iii) such other form or forms as may be required
                  under the Code or other laws of the United States as a
                  condition to exemption from, or reduction of, United States
                  withholding tax.

                  Such Bank agrees to promptly notify the Administrative Agent
         of any change in circumstances which would modify or render invalid any
         claimed exemption or reduction.

                  (b)      If any Bank claims exemption from, or reduction of,
         withholding tax under a United States tax treaty by providing IRS Form
         1001 and such Bank sells, assigns, grants a participation in, or
         otherwise transfers all or part of the obligations of the Company to
         such Bank, such Bank agrees to notify the Administrative Agent of the
         percentage amount in which it is no longer the beneficial owner of such
         obligations of the Company hereunder. To the extent of such percentage
         amount, the Administrative Agent will treat such Bank's IRS Form 1001
         as no longer valid.

                  (c)      If any Bank claiming exemption from United States
         withholding tax by filing IRS Form 4224 with the Administrative Agent
         sells, assigns, grants a participation in, or otherwise transfers all
         or part of the obligations of the Company to such Bank hereunder, such
         Bank agrees to undertake sole responsibility for complying with the
         withholding tax requirements imposed by Sections 1441 and 1442 of the
         Code.

                  (d)      If any Bank is entitled to a reduction in the
         applicable withholding tax, the Administrative Agent may withhold from
         any interest payment to such Bank an amount equivalent to the
         applicable withholding tax after taking into account such reduction. If
         the forms or other documentation required by subsection (a) of this
         Section are not delivered to the Administrative Agent, then the
         Administrative Agent

                                       53
<PAGE>   61

         may withhold from any interest payment to such Bank not providing such
         forms or other documentation an amount equivalent to the applicable
         withholding tax.

                  (e)      If the IRS or any other governmental authority of the
         United States or any other jurisdiction asserts a claim that the
         Administrative Agent did not properly withhold tax from amounts paid to
         or for the account of any Bank (because the appropriate form was not
         delivered or was not properly executed, or because such Bank failed to
         notify the Administrative Agent of a change in circumstances which
         rendered the exemption from, or reduction of, withholding tax
         ineffective, or for any other reason) such Bank shall indemnify the
         Administrative Agent fully for all amounts paid, directly or
         indirectly, by the Administrative Agent as tax or otherwise, including
         penalties and interest, and including any taxes imposed by any
         jurisdiction on the amounts payable to the Administrative Agent under
         this Section, together with all costs and expenses (including
         reasonable fees of attorneys for the Administrative Agent (including
         the allocable costs of internal legal services and all disbursements of
         internal counsel)). The obligation of the Banks under this subsection
         shall survive repayment of the Loans, cancellation of the Notes,
         cancellation or expiration of the Letters of Credit, any termination of
         this Agreement and the resignation or replacement of the Administrative
         Agent.

         13.11    Collateral Matters. The Banks irrevocably authorize the
Administrative Agent, at its option and in its discretion, (a) to release any
Lien on any property granted to or held by the Administrative Agent under any
Collateral Document (i) upon termination of the Commitments and payment in full
of all Loans and all other obligations of the Company hereunder and the
expiration or termination of all Letters of Credit; (ii) which is sold or to be
sold or disposed of as part of or in connection with any disposition permitted
hereunder; or (iii) subject to Section 14.1, if approved, authorized or ratified
in writing by the Required Banks; (b) to subordinate any Lien on any property
granted to or held by the Administrative Agent under any Collateral Document to
the holder of any Lien on such property which is permitted by subsection
10.8(d); and (c) to release any Subsidiary from its obligations under the
Subsidiary Guaranty if such entity ceases to be a Subsidiary as a result of a
transaction permitted hereunder. In addition, the Banks irrevocably authorize
the Administrative Agent, at any time on or after the Release Date, to release
Donald F. Moorehead, Jr. and Raymond M. Cash from any obligation under the
Individual Guaranty, under any Collateral Document executed pursuant thereto and
under the Individual Pledge Agreement (and to release all collateral granted
under or in connection with the foregoing). Upon request by the Administrative
Agent at any time, the Required Banks will confirm in writing the Administrative
Agent's authority to release or subordinate its interest in particular types or
items of property, or to release any Subsidiary from its obligations under the
Subsidiary Guaranty, pursuant to this Section 13.11.

         13.12    Syndication Agent. No Bank identified on the cover page, the
first page or the signature pages of this Agreement or otherwise herein as being
the "Syndication Agent" shall have any

                                       54
<PAGE>   62

right, power, obligation, liability, responsibility or duty under this Agreement
other than those applicable to all Banks. Each Bank acknowledges that it has not
relied, and will not rely, on any Person so identified in deciding to enter into
this Agreement or in taking or refraining from taking any action hereunder or
pursuant hereto.

         SECTION 14 GENERAL.

         14.1     Waiver; Amendments. No delay on the part of the Administrative
Agent or any Bank in the exercise of any right, power or remedy shall operate as
a waiver thereof, nor shall any single or partial exercise by any of them of any
right, power or remedy preclude other or further exercise thereof, or the
exercise of any other right, power or remedy. No amendment, modification or
waiver of, or consent with respect to, any provision of this Agreement or the
Notes shall in any event be effective unless the same shall be in writing and
signed and delivered by Banks having an aggregate Percentage of not less than
the aggregate Percentage expressly designated herein with respect thereto or, in
the absence of such designation as to any provision of this Agreement or the
Notes, by the Required Banks, and then any such amendment, modification, waiver
or consent shall be effective only in the specific instance and for the specific
purpose for which given. No amendment, modification, waiver or consent shall
change the Percentage of any Bank without the consent of such Bank. No
amendment, modification, waiver or consent shall (i) extend or increase the
amount of the Commitments, (ii) extend the date for payment of any principal of
or interest on the Loans or any fees payable hereunder, (iii) reduce the
principal amount of any Loan, the rate of interest thereon or any fees payable
hereunder, (iv) release any Guarantor from such Guarantor's obligations under
the applicable Guaranty or all or substantially all of the collateral granted
under the Collateral Documents or (v) reduce the aggregate Percentage required
to effect an amendment, modification, waiver or consent without, in each case,
the consent of all Banks. No provisions of Section 13 or other provision of this
Agreement affecting the Administrative Agent in its capacity as such shall be
amended, modified or waived without the consent of the Administrative Agent. No
provision of this Agreement relating to the rights or duties of an Issuing Bank
in its capacity as such shall be amended, modified or waived without the consent
of such Issuing Bank.

         14.2     Confirmations. The Company and each Bank agree from time to
time, upon written request received by it from the other, to confirm to the
other in writing (with a copy of each such confirmation to the Administrative
Agent) the aggregate unpaid principal amount of the Loans held by such Bank.

         14.3     Notices. Except as otherwise provided in Sections 2.2, 2.4 and
4.3, all notices hereunder shall be in writing (including facsimile
transmission) and shall be sent to the applicable party at its address shown on
Schedule 14.3 or at such other address as such party may, by written notice
received by the other parties, have designated as its address for such purpose.
Notices sent by facsimile transmission shall be deemed to have been given when
sent; notices sent by mail shall be deemed to have been given three Business
Days after the date when sent by registered or certified mail,

                                       55
<PAGE>   63

postage prepaid; and notices sent by hand delivery or overnight courier service
shall be deemed to have been given when received. For purposes of Sections 2.2,
2.4 and 4.3, the Administrative Agent shall be entitled to rely on telephonic
instructions from any person that the Administrative Agent in good faith
believes is an authorized officer or employee of the Company, and the Company
shall hold the Administrative Agent and each other Bank harmless from any loss,
cost or expense resulting from any such reliance.

         14.4     Computations. Where the character or amount of any asset or
liability or item of income or expense is required to be determined, or any
consolidation or other accounting computation is required to be made, for the
purpose of this Agreement, such determination or calculation shall, to the
extent applicable and except as otherwise specified in this Agreement, be made
in accordance with GAAP, consistently applied; provided that if the Company
notifies the Administrative Agent that the Company wishes to amend any covenant
in Section 10 to eliminate or to take into account the effect of any change in
GAAP on the operation of such covenant (or if the Administrative Agent notifies
the Company that the Required Banks wish to amend Section 10 for such purpose),
then the Company's compliance with such covenant shall be determined on the
basis of GAAP in effect immediately before the relevant change in GAAP became
effective, until either such notice is withdrawn or such covenant is amended in
a manner satisfactory to the Company and the Required Banks.

         14.5     Regulation U. Each Bank represents that it in good faith is
not relying, either directly or indirectly, upon any Margin Stock as collateral
security for the extension or maintenance by it of any credit provided for in
this Agreement.

         14.6     Costs, Expenses and Taxes. The Company agrees to pay on demand
all reasonable out-of-pocket costs and expenses of the Administrative Agent and
the Arranger (including the reasonable fees and charges of counsel for the
Administrative Agent and the Arranger and of local counsel, if any, who may be
retained by said counsel) in connection with the preparation, execution,
delivery and administration of this Agreement, the other Loan Documents and all
other documents provided for herein or delivered or to be delivered hereunder or
in connection herewith (including any amendments, supplements or waivers to any
Loan Documents), and all reasonable out-of-pocket costs and expenses (including
reasonable attorneys' fees, court costs and other legal expenses and allocated
costs of staff counsel) incurred by the Administrative Agent and each Bank after
an Event of Default in connection with the enforcement of this Agreement, the
other Loan Documents or any such other documents. Each Bank agrees to reimburse
the Administrative Agent for such Bank's pro rata share (based on its respective
Percentage) of any such costs and expenses of the Administrative Agent not paid
by the Company. In addition, the Company agrees to pay, and to save the
Administrative Agent, the Arranger and the Banks harmless from all liability
for, (a) any stamp or other taxes (excluding income taxes and franchise taxes
based on net income) which may be payable in connection with the execution and
delivery of this Agreement, the borrowings hereunder, the issuance of the Notes
or the execution and delivery of any other Loan Document or any other document
provided for herein or delivered or to be delivered hereunder or in connection
herewith and (b) any fees of the Company's

                                       56
<PAGE>   64

auditors in connection with any reasonable exercise by the Administrative Agent
and the Banks of their rights pursuant to Section 10.2. All obligations provided
for in this Section 14.6 shall survive repayment of the Loans, cancellation of
the Notes, cancellation or expiration of the Letters of Credit and any
termination of Agreement.

         14.7     Subsidiary References. The provisions of this Agreement
relating to Subsidiaries shall apply only during such times as the Company has
one or more Subsidiaries.

         14.8     Captions. Section captions used in this Agreement are for
convenience only and shall not affect the construction of this Agreement.

         14.9     Assignments; Participations.

         14.9.1   Assignments. Any Bank may, with the prior written consents of
the Company (so long as no Event of Default or Unmatured Event of Default
exists) and the Administrative Agent (which consents shall not be unreasonably
delayed or withheld and shall not be required in the case of an assignment by a
Lender to one of its affiliates or to another existing Lender), at any time
assign and delegate to one or more commercial banks or other Persons (any Person
to whom such an assignment and delegation is to be made being herein called an
"Assignee"), all or any fraction of such Bank's Loans and Commitment (which
assignment and delegation shall be of a constant, and not a varying, percentage
of all the assigning Bank's Loans and Commitment) in a minimum aggregate amount
equal to the lesser of (i) the amount of the assigning Bank's remaining
Commitment and (ii) $2,500,000; provided that (a) no assignment and delegation
may be made to any Person if, at the time of such assignment and delegation, the
Company would be obligated to pay any greater amount under Section 7.6 or
Section 8 to the Assignee than the Company is then obligated to pay to the
assigning Bank under such Sections (and if any assignment is made in violation
of the foregoing, the Company will not be required to pay the incremental
amounts) and (b) the Company and the Administrative Agent shall be entitled to
continue to deal solely and directly with such Bank in connection with the
interests so assigned and delegated to an Assignee until the date when all of
the following conditions shall have been met:

                  (x) five Business Days (or such lesser period of time as the
         Administrative Agent and the assigning Bank shall agree) shall have
         passed after written notice of such assignment and delegation, together
         with payment instructions, addresses and related information with
         respect to such Assignee, shall have been given to the Company and the
         Administrative Agent by such assigning Bank and the Assignee;

                  (y) the assigning Bank and the Assignee shall have executed
         and delivered to the Company and the Administrative Agent an assignment
         agreement substantially in the form of Exhibit H (an "Assignment
         Agreement"), together with any documents required to be delivered
         thereunder, which Assignment Agreement shall have been consented to by
         the Company and

                                       57
<PAGE>   65

         the Administrative Agent (to the extent applicable) and accepted by the
         Administrative Agent; and

                  (z) the assigning Bank or the Assignee shall have paid the
         Administrative Agent a processing fee of $3,500.

From and after the date on which the conditions described above have been met,
(x) such Assignee shall be deemed automatically to have become a party hereto
and, to the extent that rights and obligations hereunder have been assigned and
delegated to such Assignee pursuant to such Assignment Agreement, shall have the
rights and obligations of a Bank hereunder, and (y) the assigning Bank, to the
extent that rights and obligations hereunder have been assigned and delegated by
it pursuant to such Assignment Agreement, shall be released from its obligations
hereunder. If the Assignee was not previously a party hereto, then within five
Business Days after effectiveness of any Assignment Agreement, the Company shall
execute and deliver to the Administrative Agent (for delivery to the Assignee) a
new Note in favor of the Assignee. Any attempted assignment and delegation not
made in accordance with this Section 14.9.1 shall be null and void.

         Notwithstanding the foregoing provisions of this Section 14.9.1 or any
other provision of this Agreement, any Bank may at any time assign all or any
portion of its Loans and its Note to a Federal Reserve Bank (but no such
assignment shall release any Bank from any of its obligations hereunder).

         14.9.2   Participations. Any Bank may at any time sell to one or more
commercial banks or other Persons participating interests in any Loan owing to
such Bank, the Note held by such Bank, the Commitment of such Bank, the direct
or participation interest of such Bank in any Letter of Credit or any other
interest of such Bank hereunder (any Person purchasing any such participating
interest being herein called a "Participant"); provided that any Bank selling
any such participating interest shall give notice thereof to the Company. In the
event of a sale by a Bank of a participating interest to a Participant, (x) such
Bank shall remain the holder of its Note for all purposes of this Agreement, (y)
the Company and the Administrative Agent shall continue to deal solely and
directly with such Bank in connection with such Bank's rights and obligations
hereunder and (z) all amounts payable by the Company shall be determined as if
such Bank had not sold such participation and shall be paid directly to such
Bank. No Participant shall have any direct or indirect voting rights hereunder
except with respect to any of the events (excluding the events described in
clause (v) thereof) described in the fourth sentence of Section 14.1. Each Bank
agrees to incorporate the requirements of the preceding sentence into each
participation agreement which such Bank enters into with any Participant. The
Company agrees that if amounts outstanding under this Agreement and the Notes
are due and payable (as a result of acceleration or otherwise), each Participant
shall be deemed to have the right of setoff in respect of its participating
interest in amounts owing under this Agreement, any Note and with respect to any
Letter of Credit to the same extent as if the amount of its participating
interest were owing directly to it as a Bank under this Agreement or such Note;
provided that such right of setoff shall be subject to the obligation of each
Participant to share with the Banks, and the Banks agree to share with

                                       58
<PAGE>   66

each Participant, as provided in Section 7.5. The Company also agrees that each
Participant shall be entitled to the benefits of Section 7.6 and Section 8 as if
it were a Bank (provided that no Participant shall receive any greater
compensation pursuant to Section 7.6 or Section 8 than would have been paid to
the participating Bank if no participation had been sold).

         14.10    Governing Law. This Agreement and each Note shall be a
contract made under and governed by the internal laws of the State of Illinois.
Whenever possible each provision of this Agreement shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of this Agreement shall be prohibited by or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or invalidity,
without invalidating the remainder of such provision or the remaining provisions
of this Agreement. All obligations of the Company and rights of the
Administrative Agent and the Banks expressed herein or in any other Loan
Document shall be in addition to and not in limitation of those provided by
applicable law.

counterparts and by the different parties hereto on separate counterparts and
each such counterpart shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Agreement.

         14.12    Successors and Assigns. This Agreement shall be binding upon
the Company, the Banks and the Administrative Agent and their respective
successors and assigns, and shall inure to the benefit of the Company, the Banks
and the Administrative Agent and the successors and assigns of the Banks and the
Administrative Agent.

execution and delivery of this Agreement by the Administrative Agent and the
Banks and the agreement to extend the Commitments provided hereunder, the
Company hereby agrees to indemnify, exonerate and hold the Administrative Agent,

relating to (i) any tender offer, merger, purchase of stock, purchase of assets
or other similar transaction financed or proposed to be financed in whole or in

handling, release, emission, discharge, transportation, storage, treatment or
disposal of any hazardous substance at any property owned, leased or operated by

Indemnified Liabilities arising on account of any such Bank Party's gross
negligence or willful misconduct. If and to the extent that the foregoing
undertaking may be unenforceable for any reason, the Company hereby agrees to

Indemnified Liabilities which is permissible under applicable law. Nothing set
forth above shall be construed to relieve any Bank Party from any obligation it
may have under this Agreement.

         (b)      All obligations provided for in this Section 14.13 shall
survive repayment of the Loans, cancellation of the Notes, cancellation or
expiration of the Letters of Credit, any foreclosure under, or any modification,
release or discharge of, any or all of the Collateral Documents and any
termination of this Agreement.

NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR
OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, THE COMPANY HEREBY

Company is a corporation duly organized, validly existing and in good standing
under the laws of its jurisdiction of incorporation, has the corporate power to
own its properties and to carry on its businesses as the same are now being
conducted and is duly qualified to do business and is in good standing in each
jurisdiction in which the character of the properties owned by it or the nature
of its businesses makes such qualification necessary, except where the failure
to so qualify would not have a Material Adverse Effect. The authorized capital
stock of the Company consists of 70,000,000 shares of Common Stock, $0.0001 par
value per share, of which 11,122,784 shares are issued and outstanding and
30,000,000 shares of Preferred Stock, $.0001 par value per share, of which zero
shares of Preferred Stock are issued and outstanding. All of such outstanding
shares have been validly issued and are fully paid and nonassessable. The
Company has reserved (i) 1,304,348 shares of Common Stock for issuance pursuant
to the conversion of the 10% Convertible Subordinated Notes due October __,
2006, (ii) [3,030,565] shares of Common Stock for issuance pursuant to options
and warrants outstanding on the date hereof, (iii) 120,000 shares of Common
Stock for issuance pursuant to acquisition agreements, and (iv) 5,000,000 shares
of Common Stock for issuance in acquisitions pursuant to the Company
registration statement on Form S-1. Except as stated in this Section 4.1, the
Company has not reserved any additional shares for issuance (except as expressly
required by this Agreement) and has not issued any shares of its Common Stock.
Except for those described in the second preceding sentence, there are not
outstanding, nor is the Company subject to any agreement, arrangement, or
understanding under which there may become outstanding, any option, warrant, or
other right to purchase or subscribe to, or security convertible into or
exchangeable for, any shares of capital stock of any class of the Company. The
Company's Subsidiaries are identified in Item 1 of the Form 10-K and such Item
correctly states the jurisdiction of organization and the extent of the
Company's ownership of outstanding voting securities of each such Subsidiary.
All such voting securities are owned by the Company free and clear of any liens,
claims or encumbrances of any nature.

         4.2.     FINANCIAL STATEMENTS, SUBSEQUENT CHANGES, ETC. The Form 10-K,
one or more copies of which have been furnished to you, contains consolidated
balance sheets of the Company and its consolidated Subsidiary, and the
consolidated statements of income, stockholders' equity, and cash flows of the
Company and its consolidated Subsidiaries for each of the three years ended
December 31, 1998, including notes thereto, and the opinion of
PriceWaterhouseCoopers LLP, independent certified public accountants with
respect to such financial statements. The Form 10-Q, one or more copies of which
have been furnished to

                                       2
<PAGE>   3

you, contains the unaudited consolidated balance sheet of the Company and its
consolidated Subsidiaries at, and the unaudited consolidated statements of
income, stockholders' equity, and cash flows of the Company and its consolidated
Subsidiaries for the period ended, September 30, 1999. All of the foregoing
financial statements are complete and correct in all material respects and
fairly present in all material respects the consolidated financial condition of
the Company and its consolidated Subsidiaries at the respective dates of said
balance sheets and the consolidated results of operations of the Company and its
consolidated Subsidiaries for the respective periods covered thereby. Such
financial statements have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
involved (except as otherwise noted therein). There were no material
liabilities, direct or indirect, fixed or contingent, of the Company and its
consolidated Subsidiaries as of the respective dates of such balance sheets that
are not reflected therein or in the notes thereto. There has been no material
change in the consolidated condition, financial or otherwise, or operations of
the Company and its consolidated Subsidiaries since September 30, 1999, nor has
the Company or any Subsidiaries, except for the execution, delivery, and
performance of this Agreement, incurred any Indebtedness for borrowed money,
incurred any material liability, contingent or otherwise, except in the ordinary
course of business (including acquisitions of business and assets), or entered
into any material commitment or other transaction not in the ordinary course of
business since such date.

         4.3.     OTHER INFORMATION AS TO THE COMPANY. Each of the documents
filed by the Company with the SEC complied (the "SEC Filings") when filed in all
material respects with all of the requirements of the Securities Act and the
Exchange Act, as applicable, and did not contain any untrue statement of a
material fact or omit to state any material fact required to be contained
therein or necessary or necessary in order to make the statements therein not
misleading.

         4.4.     LITIGATION. Except as disclosed in the SEC Filings or Schedule
4.4, there is no action, suit or proceeding at law or in equity or by or before
any governmental instrumentality or agency or any arbitrator now pending or, to
the Company's knowledge, threatened, against, or affecting the Company, its
Subsidiaries or any of their respective properties or rights, which, if
adversely determined, would be reasonable likely to, either in any case or in
the aggregate result in a Material Adverse Change, or result in any substantial
liability not adequately covered by insurance, or for which adequate reserves
are not maintained on the Company's consolidated balance sheet.

         4.5.     FRANCHISES, LICENSES, TRADEMARKS, ETC. Except as disclosed in
the SEC Filings or Schedule 4.5, the Company and the Subsidiaries have all
franchises, permits, licenses and other authority as are necessary to enable it
to conduct its business as now conducted and as proposed to be conducted, and to
the best of the Company's knowledge, neither the Company nor any Subsidiary is
in default under any such franchises, permits, licenses or other authority.
Except as disclosed in the SEC Filings or Schedule 4.5, the Company and each
Subsidiaries own (or have made appropriate application for) or are duly licensed
to use trademarks, trademark rights, trade names, trade name rights, and
copyrights required to conduct its business as the same is now being operated,
to the Company's knowledge, and none of the foregoing conflict with or infringe
trademarks, copyrights, or trade names of others.

         4.6.     DUE AUTHORIZATION AND COMPLIANCE WITH OTHER INSTRUMENTS. This
Agreement and the Notes have been duly and validly authorized by all requisite
corporate proceeding and this Agreement constitutes, and the Notes when executed
and delivered will be, valid and legally binding obligations of the Company
enforceable against the Company in accordance with their terms except as
enforceability is limited by bankruptcy, insolvency, reorganization, moratorium,
or other laws relating to or affecting generally the

                                       3
<PAGE>   4

enforcement of creditors' rights and except to the extent that availability of
equitable remedies are subject to the discretion of courts before which any
proceeding therefor may be brought and the Notes will be entitled to the
benefits of this Agreement and are not subject to any preemptive or similar
rights on the part of any holder or holders of shares of capital stock of the
Company. The shares of Common Stock to be issued to you in payment of any
interest payment have been authorized for issuance, are not subject to any
preemptive or similar rights on the part of any holder or holders of shares of
capital stock of the Company and, if issued in payment of interest, will be
validly issued, fully paid and nonassessable.

         4.7.     BURDENSOME AND CONFLICTING AGREEMENTS AND VIOLATIONS OF
CHARTER PROVISIONS. Neither the Company nor any Subsidiary is bound by any
agreement or instrument or subject to any charter or other corporate restriction
which materially and adversely affects its business, properties, operations,
prospects or condition, financial or otherwise. The Company is not in violation
of its charter or by-laws or of any agreement or instrument by which it is
bound, or of any statute, law, rule or regulation, or of any judgment, decree,
writ, injunction, order or award of any arbitrator, court or governmental
authority applicable to it, in a manner that could result in the imposition of
substantial penalties or result in a Material Adverse Change. Neither the
authorization, execution and delivery of this Agreement or the Notes, the
issuance and delivery of shares of Common Stock in payment of interest, the
consummation of the transactions herein and therein contemplated, nor the
fulfillment of or compliance with the terms hereof and thereof, will conflict
with or result in a breach of any of the terms of the charter or by-laws, or of
any material statute, law, rule or regulation, or of any judgment, decree, writ,
injunction, order or award of any arbitrator, court or governmental authority,
or of any instrument, which is applicable to the Company or its Subsidiaries or
by which the Company or any Subsidiary is bound, or result in the imposition of
any lien upon any of the properties or assets of the Company or its
Subsidiaries.

         4.8.     CONSENTS AND APPROVALS. The Company has obtained or made
provisions to obtain all material (a) governmental consents, approvals and
authorizations, and registrations and filings with governmental authorities, and
(b) consents, approvals, waivers and notifications of stockholders, creditors,
lessors and other non-governmental persons, in each case, in connection with the
execution and delivery of this Agreement and the Notes, and the consummation of
the transactions herein and therein contemplated.

         4.9.     TAX RETURNS AND PAYMENTS. The Company and its Subsidiaries
have filed all required information and tax returns and reports and have paid,
or adequately provided for the payment of, all taxes, assessments and other
governmental charges that are material in amount respectively imposed upon them
or upon any of their respective assets, income or franchises, other than any
such charges which are currently payable without penalty or interest. The
charges, accruals and reserves on the books of the Company and the Subsidiaries
with respect to taxes for all fiscal periods are adequate, in the opinion of the
Company, and neither the Company nor any Subsidiary knows of any actual or
proposed tax assessment that is material in amount for any fiscal period or of
any basis therefor against which adequate reserves have not been set up. The
Company has not been advised that any federal income tax or information return
of the Company or any Subsidiary has been, or will be, examined or audited by
the Internal Revenue Service.

         4.10.    OFFERING OF THE SECURITIES. Neither the Company nor anyone
authorized to act on its behalf has or will directly or indirectly sell or offer
the Securities or any part thereof or any similar securities to, or solicit any
offer to buy any thereof from, any Person so as to bring the issue and sale of
any thereof within the provisions of Section 5 of the Securities Act.

         4.11.    OTHER ADVERSE FACTS, ETC. To the best of the Company's
knowledge, there are no existing facts or circumstances which materially and
adversely affect, or (insofar as the Company can now reasonably foresee) in the
future may materially and adversely affect, the business, prospects, results of
operations or condition, financial or otherwise, of the Company and the
Subsidiaries, on a consolidated basis, which are not disclosed in the Form 10-K,
the Form 10-Q, other documents filed with the SEC pursuant to the Exchange Act,
or in this Agreement or any exhibit hereto, or which are required to be
disclosed by the Company in an Exchange Act filing.

Subsidiary is either (i) a "public utility company" or a "holding company", or
an "affiliate" or a "subsidiary company" of a "holding company", or an
"affiliate" of such a "subsidiary company", as such terms are defined in the
Public Utility Holding Company Act of 1935, as amended, or (ii) a "public
utility" as defined in the Federal Power Act, as amended, or (iii) an

                  under the Senior Obligations; and

         5.3.     NOTICE OF PREPAYMENT. The Company will give each holder of any

         in one transaction or a series of related transactions, if, immediately
         after giving effect to such transaction(s), any "person" or "group" (as
         such terms are used for purposes of Sections 13(d) and 14(d) of the
         Exchange Act, whether or not applicable), is or becomes the beneficial
         owner (as such term is used in Rule 13d-3 of the Exchange Act or any
         successor provision thereto), directly or indirectly, of more than 50%
         of the total voting power in the aggregate normally entitled to vote in

         (other than a planned retirement) to constitute a majority of the Board
         of Directors of the Company then in office, as applicable;
provided, however, that any transaction that would otherwise fall within clause
(i), (ii), or (iii) with respect to which discussions between the Company and
the other Person to such transaction were initiated prior to the date hereof.

         The "Change of Control Purchase Price" means 100% of the principal
amount of the Notes, if a Change of Control occurs on or prior to the second
anniversary of the Closing Date;

         (c)      On or before the Change of Control Purchase Date, the Company
will (i) accept for payment the Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (ii) promptly pay the Holders of Notes
so accepted an amount equal to the Change of Control Purchase Price (together

                  Default or Event of Default shall have occurred and be
                  continuing.

         No such conveyance, transfer or lease of substantially all of the

         7.11     OTHER SUBORDINATED INDEBTEDNESS. The Company shall not incur

         8.1.     PLACE OF PAYMENT. The Company will promptly and punctually pay
the interest on the Notes held by you without any presentment thereof; and the
Company will pay all amounts payable to you in respect of principal of and

writing.

         8.2.     REGISTRATION AND TRANSFER. The Company agrees to maintain an
office (or to appoint an agent having an office) in Dallas, Texas, or such other
city as the Company may designate by notice in writing to you, at which Notes
may be surrendered for transfer and reissuance, for exchange, replacement, or
cancellation. The Company shall keep or cause to be kept, at the office or
agency so maintained, a register or registers in which the Company or its agent
shall register the names and addresses of the Holders and shall transfer
registered Notes in accordance with this Agreement. Upon surrender for transfer
of any registered Note duly assigned by the registered holder (or its duly
authorized attorney) to the transferee(s) thereof and subject to satisfaction of
the requirements set forth in Section 12.4 if such Note is then a Restricted
Note, the Company shall execute and deliver a new registered Note (or Notes in
appropriately subdivided denominations of principal), dated the most recent date
to which interest shall have been paid on the surrendered Note, in an equal
principal amount with notation of payments of principal made thereon, or in a
principal amount equal to the original principal amount as reduced by payments
of principal theretofore made on the Note surrendered, in the name of, and
payable to the order of, the transferee(s) thereof. No service charge shall be
assessed for any transfer, registration, reissuance, exchange, or notation of
payment hereunder.

of a 365-day year at a rate of 12% per annum from the Closing Date, payable in
equal semiannual installments on each Interest Payment Date of each year (or

until the principal on the Notes becomes due and payable. To the extent
permitted by law, interest on any overdue payment of principal or interest shall
be payable quarterly at a rate equal to 18% per annum.

         Interest on the Notes shall be payable on each Interest Payment Date in
cash or, at the option of the Company, by the issuance to the Holder of shares
of Common Stock with a

                                       11
<PAGE>   12

on such Interest Payment Date;

         8.4      COMMON STOCK ISSUED IN PAYMENT OF INTEREST. Any shares of
Common Stock issued pursuant to Section 8.3 shall be validly issued, fully paid
and nonassessable shares of the Common Stock of the Company and shall be subject
to the restrictions on transfer set forth in Section 12 hereof.

         9.       SUBORDINATION OF NOTES. The Company covenants and agrees, and
each holder of a Note, by acceptance thereof, likewise covenants and agrees (i)
that, to the extent and in the manner set forth in this Section 9, the Company's
Senior Obligations (as defined in Section 9.1), if any, will be senior in right
of payment to the Notes, and (ii) that the subordination provisions set forth in
this Section 9 are, and are intended to be, an inducement and a consideration to
each holder of any Senior Obligations, whether such Senior Obligation was
created or acquired before or after the date of this Agreement, to acquire and
continue to hold, or to continue to hold, such Senior Obligation, and each
holder of Senior Obligations shall be deemed conclusively to have relied on such
subordination provisions in acquiring and continuing to hold, or continuing to
hold, such Senior Obligations.

         9.1.     SUBORDINATION TO SENIOR OBLIGATIONS. As used herein, "senior
in right of payment to the Notes" means that:

                  (a) no part of the Debt shall have any claim to the assets of
         the Company on a parity with or prior to the claim of the Senior
         Obligations; and

                  (b) unless and until the Senior Obligations have been paid in
         full, without the express prior written consent of all holders of such
         Senior Obligations, no Holder will take, demand (including by means of
         any legal action) or receive from the Company, and the Company will not
         make, give or permit, directly or indirectly, by set-off, prepayment,
         purchase or in any other manner, any cash payment of or security for
         the whole or any part of the Debt; provided, however, that (x) so long
         as no default exists in the payment of any principal of or premium, if
         any, or interest on any Senior Obligations, the Company may make, and
         the Holders may receive, scheduled payments on account of the Debt in
         accordance with the terms hereof, except if a default in the
         performance or observance of any term or condition relating to any
         Senior Obligations (other than a default in the payment of any
         principal of or premium, if any, or interest on the Senior Obligations)
         has occurred and is continuing that permits the holders of the Senior
         Obligations to declare such Senior Obligations to be due and payable,
         any Designated Holder of Senior Obligations (as defined in Section 9.6)
         may give notice (a "Senior Blockage Notice") to the Company (provided,
         however, no more than one Senior Blockage Notice may be given during
         any 360 consecutive day period) that until all Senior Obligations are
         paid in full, no scheduled payments (whether in cash or securities, but
         excluding additional Notes) may be made by the Company on account of
         the Debt during the period ("Senior Blockage Period") commencing on the
         date of such Senior Blockage Notice and ending on the earliest of: (A)
         180 days after the date of such Senior Blockage Notice; (B) the date
         such default is cured or waived; and (C) the date that the holders of
         the Senior Obligations shall have given notice to the Company of
         termination of the Senior Blockage Period, and except when a default in
         the payment of any principal of, premium if any, or interest on the
         Senior Obligations has occurred and is continuing or would result
         therefrom, and (y) upon the acceleration of the maturity of any Senior
         Obligations, the Holders may accelerate the scheduled maturities of the
         Notes if and to the extent permitted hereby at such time but such
         acceleration shall not give (i) any Holder any right

                                       12
<PAGE>   13

         to take, demand (including by means of any legal action) or receive
         from the Company, or (ii) the Company the right to make, give or
         permit, directly or indirectly, by set-off, prepayment, purchase or in
         any other manner, any cash payment of or security for the whole or any
         part of the Notes unless and until the Senior Obligations have been
         paid in full.

         9.2.     PAYMENTS DUE HOLDERS OF SENIOR OBLIGATIONS. Any payment or
distribution by the Company to which any Holder would be entitled except for the
provisions hereof (whether in cash or securities, but excluding additional
Notes) shall be paid or delivered by the Holder, or any receiver, trustee in
bankruptcy, liquidating trustee, disbursing agent or other Person making such
payment or distribution, to the holders of the Senior Obligations or their
representative, ratably in accordance with the amounts thereof, to the extent
necessary to pay in full all Senior Obligations, before any payment or
distribution shall be made to any Holder.

         9.3.     MEANING OF PAYMENT IN FULL. The expressions "prior payment in
full," "payment in full," "paid in full" and any other similar terms or phrases
when used herein with respect to the Senior Obligations shall mean the payment
in full in cash of all of the Senior Obligations; and the expression "any cash
payment of or security for the whole or any part of the Debt" and any other
similar terms or phrases when used herein shall not be deemed to include a
payment or distribution of stock or securities of the Company provided for by a
plan of reorganization or readjustment authorized by an order or decree of a
court of competent jurisdiction in a reorganization proceeding under any
applicable bankruptcy law, or of any other corporation provided for by such plan
of reorganization or readjustment, which stock or securities are subordinated in
right of payment to all then outstanding Senior Obligations to substantially the
same extent as the Notes are so subordinated as provided in this Section 9.7.

another Person or the liquidation or dissolution of the Company following the
conveyance or transfer of all or substantially all of its properties and assets
as an entirety to another Person upon the terms and conditions set forth in
Section 7.9 shall not be deemed a "proceeding" for the purposes of this Section
9.7 if the Person formed by such consolidation or into which the Company is
merged or the Person which acquires by conveyance or transfer such properties
and assets as an entirety, as the case may be, shall, as a part of such

(iv) under or in connection with any other secured Indebtedness of the Company
having an initial principal amount in excess of $5,000,000 which by its express
terms states that it is a "Senior Obligation"; in each case (a) whether direct

hereafter incurred, and (b) whether on account of principal, premium, interest
(including, without limitation, interest accruing after the maturity date of any

Notes, whether direct or indirect, absolute or contingent, due or to become due,

         9.10.    OBLIGATIONS UNIMPAIRED. Nothing contained in this Section 9 is
intended to or shall impair as between the Company, its creditors other than the
holders of Senior Obligations and the Holders, the obligation of the Company,
which shall be absolute and unconditional, to pay to the Holders the principal
of and interest on the Notes, as and when the same will become due and payable
in accordance with the terms thereof, or to affect the relative rights of the
Holders and creditors of the Company other than the holders of Senior
Obligations, nor shall anything herein or therein prevent the holder of any Note
from exercising all remedies otherwise permitted by applicable law upon default,
subject to the rights, if any, under this Section 9 of the holders of Senior
Obligations in respect of any required notice of the exercise of any such remedy
or cash, property, or securities of the Company received upon the exercise of
any such remedy.

purchaser of the Notes, shall be a contractual obligation of such purchaser) and
upon surrender, at the office or agency maintained in accordance with Section 8,
and cancellation of any Note, if mutilated, the Company will execute and deliver
a new Note of like tenor, in lieu of such Note, dated the most recent date to
which interest on such Note shall have been paid.

the Notes when and as the same shall become due and payable, either at maturity
or by acceleration or otherwise;

         (B)      default shall be made in the payment of interest on the Notes
when the same becomes due and payable and the default continues for a period of
30 days;

                  (c)      default shall be made in the due performance or
         observance of any other material covenant, agreement, or provision
         herein to be performed or observed by the Company or a material breach
         shall exist in any representation or warranty herein contained, and
         such default or material breach shall have continued for a period of 30
         days after written notice thereof to the Company from any holder or
         Holders of Notes aggregating not less than 51% of the aggregate
         principal amount of the Notes then outstanding; provided, however, that
         if any such default or material breach shall be such that it cannot be
         cured or corrected within such 30-day period, such period shall be
         extended for such additional period of time (not exceeding 30
         additional days) as shall be necessary to effect such cure or
         correction if curative or corrective action is instituted within said
         30-day period and thereafter diligently pursued;

                  (d)      the Company or any Subsidiary shall (i) apply for or
         consent to the appointment of a receiver, trustee, or liquidator of the
         Company or such Subsidiary or any of their respective assets, (ii) make
         a general assignment for the benefit of creditors, (iii) be adjudicated

                                       15
<PAGE>   16

         petition in bankruptcy, or a petition or answer seeking reorganization
         or an arrangement with creditors to take advantage of any bankruptcy,
         reorganization, insolvency, readjustment of debt, moratorium,
         dissolution, liquidation, or debtor relief law, or any chapter of any
         such law, or an answer admitting the material allegations of a petition
         filed against it in any proceeding under any such law or chapter, or
         corporate action shall be taken by the Company or any Subsidiary for
         the purpose of effecting any of the foregoing; or an order, judgment,
         or decree shall be entered, without the application, approval, or
         consent of the Company or a Subsidiary, by any court of competent
         jurisdiction, approving a petition seeking liquidation or
         reorganization of the Company or such Subsidiary, as applicable, of all
         or a substantial part of the assets of the Company or such Subsidiary;
         and provided that such order, judgment, or decree remains in effect for
         more than 30 days, whether or not consecutive;

                  (e)      a Senior Obligations Default shall occur and continue
         for a period of 90 days;

                  (f)      default shall occur with respect to any other
         Indebtedness for borrowed money of the Company or any Subsidiary (other
         than the Notes or Senior Obligations) or under any agreement under
         which such Indebtedness may be issued by the Company or such Subsidiary
         and such default shall continue for more than the period of grace, if
         any, therein specified, if the aggregate amount of such Indebtedness
         for which such default shall have occurred exceeds $500,000; or

                  (g)      final judgment for the payment of money in excess of
         $500,000 shall be rendered against the Company or any Subsidiary and
         the same shall remain undischarged for a period of 60 days during which
         execution shall not be effectively stayed;

then and in each and every such case the Holders of Notes aggregating not less
than 51% of the aggregate principal amount of the Notes then outstanding may by
notice in writing to the Company declare the unpaid principal of the Notes
together with accrued interest thereon to be forthwith due and payable and
thereupon such principal and interest shall be due and payable without
presentment, protest, or further demand or notice of any kind, all of which are
hereby expressly waived.

         This Section 11, however, is subject to the condition that, if at any
time after the principal of the Notes shall have become so due and payable, and
before any judgment or decree for the payment of the moneys so due, or any
thereof, shall be entered and if all arrears of interest upon the Notes and all
other sums payable under the Notes (except the principal on the Notes which
solely by reason of such declaration shall have become payable) shall have been
duly paid, then and in every such case the Holders of Notes aggregating not less
than 66-2/3% of the aggregate principal amount of the Notes then outstanding
may, by written notice to the Company, either temporarily suspend or permanently
rescind and annul such declaration and its consequences; but no such suspension
or rescission and annulment shall extend to or affect any prior, concurrent, or
subsequent default or Event of Default (other than the ones identified by the
Holders declaring them due as the ones upon which such declaration was based) or
impair any right consequent thereon.

         Notwithstanding anything to the contrary herein, if default shall be
made in the payment of any principal of, or interest on, any Note when and as
the same shall become due and payable, at maturity (but not merely by virtue of
an acceleration pursuant to the foregoing provisions of this Section 11), the
holder of such Note may by notice in writing to the Company declare the unpaid
principal of such Note, with accrued interest, to be forthwith due and payable
and thereupon such principal and interest shall be due and payable

                                       16
<PAGE>   17

without presentment, protest, or further demand or notice of any kind, all of
which are hereby expressly waived.

         If any holder of a Note shall demand payment thereof or take any other
action (of which the Company has actual knowledge) in respect of an Event of
Default, the Company will forthwith give written notice thereof, specifying such
action and the nature of such event, to each holder of record of the Notes then
outstanding. The Company will also give prompt written notice to each holder of
record of the Notes at the time outstanding of any written notice of suspension,
rescission, or annulment given to it as aforesaid.

         The Company covenants that, if default be made in any payment of
principal of or interest on any Note, it will pay to the holder thereof such
further amount as shall be reasonably sufficient to cover the cost and expense
of collection, including, without limitation, court costs and reasonable
compensation to the attorneys and counsel of the holder for all services
rendered in that connection.

         No course of dealing between the Company and any holder of a Note or
any delay on the part of the holder of a Note in exercising any rights
thereunder or hereunder shall operate as a waiver of any rights of any such
holder.

an opinion, such holder shall be entitled to transfer such security in
conformity with the terms of such notice, and, if the opinion of counsel so

                           14901 Quorum Drive, Suite 200

in each year, or portion thereof, during which such holder held a Note, even
though no cash payment with respect to such original issue discount would have
been received. The Treasury Regulations under Section 1273 require the Company
and the purchasers of the Notes to make certain joint determines concerning
original issue discount. The Company will use its best efforts to provide the
holders of the Notes with its allocation of the purchase price of the Securities
among the Notes and the Warrants within thirty (30) days following the Closing.

determining the amount of original issue discount attributable to the Notes and
in reporting such discount on their respective tax returns.

interest on any Note become due and payable upon a day other than a day on which
national banks located in Texas, are open for the conduct of banking business,
the maturity thereof shall be extended to the next succeeding day upon which
such banks are open for the conduct of banking business and, in the case of an
installment of principal, interest shall be payable thereon at the rate per
annum specified in such Note during such extension.

         22.      HEADINGS. The headings of the various sections and subsections
hereof have been inserted for convenience of reference only and shall not be
deemed to in any way modify any of the terms or provisions hereof.

hereto upon a separate copy, in which event all of said copies shall constitute
a single counterpart of this Agreement. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original, and it shall not
be necessary in making proof of this Agreement to produce or account for more
than one such counterpart.
