This Amendment No. 1 (this "Amendment") amends and supplements the
Tender Offer Statement on Schedule 14D-1 originally filed with the Securities
and Exchange Commission on March 23, 1999 (the "Schedule 14D-1") relating to the
tender offer by Arkansas Best Corporation, a Delaware corporation ("Parent"), to
purchase all of the outstanding shares of the common stock, par value $.01 per
share (the "Common Stock") including the associated common stock purchase rights
(the "Rights" and, together with the Common Stock, the "Shares") of Treadco,
Inc., a Delaware corporation (the "Company"), at a purchase price of $9.00 per
Share, net to the seller in cash, without interest, upon the terms and subject
to the conditions set forth in the Offer to Purchase, dated March 23, 1999 (the
"Offer to Purchase"), a copy of which is attached as Exhibit (a)(1) to the
Schedule 14D-1, which, together with any amendments or supplements thereto,
constitute the "Offer." This Statement also amends and supplements the Schedule
13D of Parent, originally filed on September 18, 1998, as amended by Amendment
No. 1 thereto filed on January 26, 1999 and Amendment No. 2 thereto filed March
23, 1999.

ITEM 5. PURPOSE OF THE TENDER OFFER AND PLANS OR PROPOSALS OF THE BIDDER.

(f) Item 5(f) is hereby amended by the following:

The information incorporated by reference from the third
paragraph under "SPECIAL FACTORS --Purpose and Structure of
the Transaction" of the Offer to Purchase, filed as Exhibit
(d)(1), is amended by deleting such information and
substituting therefore:

The present requirement to maintain the listing of
the Shares on the Nasdaq National Market and
registration of the Shares under the Exchange Act,
coupled with the Company's status as a public
company, impose on the Company direct and indirect
compliance costs. Compliance with such ongoing
requirements imposes an administrative burden on the
Company, resulting in the diversion of management
time and resources.

The Parent's management estimates that the following
compliance, public company-related, and other costs
would be eliminated after consummation of the
Transaction:

<TABLE>
<S> <C>
Directors insurance and fees $200,000
Annual public reporting expenses $167,500
Higher interest rate cost $ 60,000
--------
Total pre-tax savings of the above items $427,500
--------
After-tax savings $261,203
State tax savings $ 35,741

Total after-tax savings including state tax savings $296,943

After-tax savings from goodwill reductions $462,000

ITEM 10. ADDITIONAL INFORMATION.

(f) Item 10(f) is hereby amended by the following:

The disclaimer that reads: "NONE OF THE COMPANY OR PARENT OR
THEIR RESPECTIVE ADVISORS ASSUMES ANY RESPONSIBILITY FOR THE
ACCURACY OF THE PROJECTIONS," which is incorporated by
reference from the fourth sentence of the second paragraph of
"SPECIAL FACTORS -- Certain Projections" of the Offer to
Purchase, filed as Exhibit (d)(1), is amended by deleting such
information.

The information incorporated by reference from the first
paragraph of "THE TENDER OFFER -- Certain Conditions of the
Offer" of the Offer to Purchase, filed as Exhibit (d)(1), is
amended by deleting such information and substituting
therefore:

Notwithstanding any other provisions of the
Offer, Parent shall not be required to accept for
payment or pay for and may delay the acceptance for
payment of, or the payment for, any Shares, and may
terminate the Offer and not accept for payment or pay
for any Shares, if (i) immediately prior to the
expiration of the Offer (as it may be extended in
accordance with the Offer), the Minimum Condition
shall not have been satisfied, (ii) any applicable
waiting period under the HSR Act shall not have
expired or been terminated prior to the expiration of
the Offer; (iii) any required consent, permit or
authorization from any regulatory or governmental
authority has not been obtained prior to the
Expiration Date; or (iv) at any time prior to the
Expiration Date, Parent makes a determination (which
shall be made in good faith) that any of the
following conditions exist:

The disclosure that reads: "Because such analyses are
inherently subject to uncertainty, none of the Company, Parent
or Stephens or any other person assumes responsibility if
future events do not conform to the judgments reflected in the
opinion of Stephens," which is incorporated by reference from
the last sentence of the second paragraph of "SPECIAL FACTORS
-- Opinion of Financial Advisor" of the Offer to Purchase,
filed as Exhibit (d)(1), is amended by deleting such
information and substituting therefore:

"Such analyses are inherently subject to uncertainty
and actual results could differ significantly from
current expectations due to a number of factors,
including general economic conditions; competitive
initiatives and pricing pressures; labor relations;
costs of raw material; availability and cost of
capital; shifts in market demand; weather conditions;
the performance and needs of industries served by the
Company's businesses; actual future costs of
operating expenses; self-insurance claims and
employee wages and benefits; actual costs of
continuing investments in technology; and the timing
and amount of capital expenditures."

The following text is to be inserted after the sixth paragraph
of "SPECIAL FACTORS -- Background of the Offer and the Merger"
of the Offer to Purchase, filed as Exhibit (d)(1):

In November 1998, Morgan Stanley began
reviewing with Parent its options with respect to the
Company. Representatives of Morgan Stanley made a
presentation regarding these alternatives to Parent's
Board of Directors at its regular meeting on December
10, 1998. Morgan Stanley, among other things,
presented an historical overview of the Company,
discussed its financial condition and results of
operations, reviewed the stock's liquidity,
identified the Company's research coverage, and
discussed the Company's possible strategic value to
Parent. Morgan Stanley reviewed the following
strategic alternatives with Parent's Board of
Directors: (i) Parent continuing to hold its 49%
interest in the Company, (ii) sale of 100% of the
Company, and (iii) a Parent repurchase of the
remaining Company interest held by the public with a
potential strategic sale in the future. Morgan
Stanley also reviewed certain considerations such as
tax considerations, the Bandag settlement, the
revenue and earnings of the business, other potential
strategic buyers, estimated strategic value, cost
savings associated with having the Company as a
wholly-owned subsidiary of Parent, and the long-term
strategic fit with Parent. In addition, Morgan
Stanley reviewed the process, timelines and potential
after-tax proceeds associated with either a
repurchase of shares or an immediate sale of the
Company. Morgan Stanley also discussed other
potential economic benefits to Parent associated with
repurchasing the Company.

Morgan Stanley was not requested to, and did
not, render a financial opinion regarding the
fairness of the consideration in the Offer and the
Merger. In addition, Morgan Stanley was not requested
to, and did not, solicit third party indications of
interest with respect to Parent's interest in the
Company. See "THE TENDER OFFER -- Fees and Expenses"
for a description of Parent's fee arrangements with
Morgan Stanley in connection with the Offer and the
Merger.

On April 14, 1999, the Company issued a press release
regarding the 1999 first quarter operating results, a copy of
which is attached hereto as Exhibit (a)(10) and is
incorporated herein by reference.

PRESS RELEASE OF ABC DATED JANUARY 22, 1999

FOR IMMEDIATE RELEASE

ARKANSAS BEST CORPORATION PROPOSES A MERGER IN WHICH THE
PUBLICLY-HELD SHARES OF TREADCO, INC. WOULD BE ACQUIRED AT $9.00
PER SHARE IN CASH

(NASDAQ/NMS: "ABFS"; WWW: ARK BEST.COM)

(Fort Smith, Arkansas, January 22, 1999) -- Arkansas Best Corporation (ABFS) and
Treadco, Inc. (TRED) announced today that Arkansas Best has submitted a formal
proposal to Treadco's Board of Directors in which the outstanding shares of
Treadco's common stock not owned by Arkansas Best would be acquired for $9.00
per share in cash. The proposal has the support of Shapiro Capital Management
Company, Inc., Treadco's largest independent stockholder, which beneficially
owns 1,132,775 shares (or approximately 22%) of the common stock of Treadco.
Arkansas Best currently owns approximately 49% of Treadco.

Treadco will form a special committee of independent directors to consider
Arkansas Best's proposal. The proposal to acquire the remaining outstanding
shares of Treadco is subject to the approval of Treadco's special committee and
the negotiation of a definitive agreement, which will include customary
conditions to closing.

The foregoing release contains forward-looking statements that are based on
current expectations and are subject to a number of risks and uncertainties.
Actual results could differ materially from current expectations due to a number
of factors, including general economic conditions; competitive initiatives and
pricing pressures; union relations; availability and cost of capital; shifts in
market demand; weather conditions; the performance and needs of industries
served by Arkansas Best's and Treadco's businesses; actual future costs of
operating expenses such as fuel and related taxes; self-insurance claims and
employee wages and benefits; actual costs of continuing investments in
technology; and the timing and amount of capital expenditures.

TREADCO, INC. REPORTS 1999 FIRST QUARTER OPERATING RESULTS

April 14, 1999 02:49 PM FORT SMITH, Ark., April 14 /PRNewswire/ -- Treadco, Inc.
TRED today reported a net loss of $482,444, or $0.10 per common share (basic and
diluted), for the 1999 first quarter, which includes non-recurring charges of
approximately $0.06 per common share (basic and diluted). Without these non-
recurring charges, Treadco's loss was approximately $172,444, or $0.04 per
common share (basic and diluted). This compares to a net loss of $627,466, or a
loss of $0.12 per common share (basic and diluted), for the first quarter of
1998.

The non-recurring charges total approximately $310,000 and represent investment
banking and legal expenses related to the fairness opinion provided to the
special committee of independent directors of Treadco regarding the current
$9.00 per share tender offer by Arkansas Best Corporation for the Treadco shares
not already owned by Arkansas Best. The $310,000 non-tax deductible charge is
included in other non-operating expense.

During the quarter, Treadco had sales of $40.9 million which represents a 9.2%
increase over the same period of 1998. Treadco's operating loss was $255,414
compared to a 1998 first quarter operating loss of $576,494.

The foregoing release contains forward-looking statements that are based on
current expectations and are subject to a number of risks and uncertainties.
Actual results could differ materially from current expectations due to a number
of factors, including general economic conditions; competitive initiatives and
pricing pressures; availability and cost of capital; shifts in market demand;
weather conditions; government regulations; the performance and needs of
industries served by Treadco; actual future costs of operating expenses such as
the price of oil; self-insurance claims and employee wages and benefits; and the
timing and amount of capital expenditures.

<PAGE> 9
The foregoing ratio (a) shall be established at Tier Level III for the
period from the Effective Date through June 30, 1998, and (b) shall thereafter
be determined from the financial statements of the Borrower and its
Consolidated Subsidiaries most recently delivered pursuant to Section 5.6(a) or
Section 5.6(b) and certified to by an authorized financial officer of the
Borrower in accordance with such Sections. Any change in the Applicable Margin
shall be effective upon the date of delivery of the financial statements
pursuant to Section 5.6(a) or Section 5.6(b), as the case may be, and receipt
by the Agent of the Compliance Certificate required by such Sections. If the
Borrower fails to deliver any financial statements within the times specified
in Section 5.6(a) or 5.6(b), as the case may be, such ratio shall be (i)
established at Tier Level I from the date such financial statements should have
been delivered until the Borrower delivers such financial statements to the
Agent and the Banks, and (ii) when such financial statements are in fact
received by the Agent and the Banks, if it is determined that the actual ratio
was less than that established at Tier Level I, then the Applicable Margin for
the period from the date such financial statements should have been delivered
until the date the Agent and the Banks actually received such financial
statements shall be recalculated to reflect the actual ratio for such period of
time, and if interest or fees have been paid in the period prior to such
recalculation, appropriate adjustment shall be made to the next scheduled
payment of interest or fees to be made by the Borrower.

Notwithstanding the foregoing but subject to the paragraph below, if at
any time, the Borrower's Senior Debt is rated BB+ or higher by S&P or Ba1 or
higher by Moody's, then "Applicable Margin" shall mean, at any time with
respect to any Revolving Advance, commitment fees or letter of credit fees
hereunder, the following percentages determined as a function of the ratings by
S&P or Moody's applicable on such date of the Borrower's Senior Debt as set
forth below:

IV BB+ Ba1 0.625% 0.000% 0.2000% 0.500%
</TABLE>

If ratings fall within different Tier Levels, the Applicable Margin shall be
based on the numerically lower of the two Tier Levels (where Tier I is the
numerically lowest such Tier and Tier IV is the numerically highest such Tier)
unless the numerically higher Tier Level is two or more Tier Levels above the
numerically lower Tier Level, in which case the Tier Level which is one level
above the numerically lower Tier Level will apply. In the event that one
rating falls within Tier Level IV and the other such rating is one rating level
immediately below (ie. either

-3-
<PAGE> 10
BB or Ba2), then the Applicable Margin will be based on Tier Level IV;
provided, however that if the other such rating differs by more than one rating
immediately below (ie. either BB- or Ba3 or lower), then the Applicable Margin
shall be determined by reference to the Leverage Ratio as provided above. If
the ratings established by Moody's or S&P for Senior Debt change (other than as
a result of a change in the rating system of Moody's or S&P), such change shall
be effective as of the date on which it is first announced by the applicable
rating agency. If the rating system of either Moody's or S&P shall change when
a rating for Senior Debt exists from both Moody's and S&P or if either such
rating agency shall cease to be in the business of rating corporate debt
obligations while the other remains in such business, the Applicable Margin
shall be based on the rating of the agency that has not changed its rating
system or that remains in the business of rating corporate debt obligations.
If both Moody's and S&P shall change their rating system, cease rating the
Borrower's Senior Debt or cease to be in the business of rating corporate debt
obligations, then the Borrower and the Agent shall select a substitute
nationally recognized statistical rating agency or agencies, as the case may
be; provided, however that if the Borrower and the Agent cannot mutually agree
on such a substitute rating agency, the Applicable Margin shall be determined
by reference to the Borrower's Leverage Ratio as provided above.

substantially the form of the attached Exhibit G.

THE ADVANCES AND THE LETTERS OF CREDIT

Section II.1 The Advances.

(1) Revolving Advances. Each Bank severally agrees, on the
terms and conditions set forth in this Agreement, to make Revolving Advances to
the Borrower from time to time on any Business Day prior to the Maturity Date
in an aggregate amount not to exceed at any time outstanding an amount equal to
such Bank's Revolving Commitment less such Bank's Pro Rata Share of the Letter
of Credit Exposure at such time. The aggregate amount of all

-20-
<PAGE> 27
outstanding Revolving Advances, Swingline Advances and Letter of Credit
Exposure at any time may not exceed the lesser of (i) the aggregate Revolving
Commitments at such time or (ii) the Borrowing Base at such time. Within the
limits of each Bank's Revolving Commitment and the Borrowing Base limitation
set forth above, the Borrower may from time to time prepay pursuant to Section
2.7 and reborrow under this Section 2.1(a).

(2) Swingline Advances. On the terms and conditions set
forth in this Agreement, SG may, in its sole discretion from time-to-time on
any Business Day during the period from the date of this Agreement until the
Maturity Date, make advances ("Swingline Advances") under the Swingline Note to
the Borrower in an aggregate principal amount not to exceed $15,000,000
outstanding at any time; provided that the aggregate principal amount of
outstanding Revolving Advances, Swingline Advances, and Letter of Credit
Exposure may not exceed the lesser of (i) the aggregate Revolving Commitments
at such time or (ii) the Borrowing Base at such time; and provided further than
no Swingline Advance shall be made by SG if the statements set forth in Section
3.2(a) are not true on the date of such Swingline Advance, it being agreed by
the Borrower that the giving of the applicable Notice of Borrowing and the
acceptance by the Borrower of the proceeds of such Swingline Advance shall
constitute a representation and warranty by the Borrower that on the date of
such Swingline Advance such statements are true. Subject to the other
provisions hereof, the Borrower may from time-to-time borrow, prepay (in whole
or in part) and reborrow Swingline Advances.

(1) Except as provided in the following clause (B)
below, each request for a Swingline Advance shall be made pursuant to
telephone notice to SG given no later than 11:00 a.m. (Dallas, Texas time)
on the date of the proposed Swingline Advance, promptly confirmed by a
completed and executed Notice of Borrowing telecopied to the Agent. SG
will promptly make the Swingline Advance available to the Borrower at the
Borrowers' account with the Agent.

(2) The Borrower and the Banks agree that in the
event any Swingline Advance is not repaid on the date due to SG, each Bank
shall pay to the Agent its Pro Rata Share of such Swingline Advance and
such payment shall be deemed to be a Prime Rate Advance made pursuant to
such Bank's Revolving Commitment, whether made before or after termination
of the Commitments, acceleration of the Advances, or otherwise, and
whether or not the conditions precedent in Section 3.2 have been
satisfied. The Agent shall give each Bank notice of such Mandatory
Revolving Borrowing by 11:00 a.m. (Dallas, Texas time) on the date the
Mandatory Revolving Borrowing is to be made. Each Bank shall make its
Advance available to the Agent for the account of SG in immediately
available funds by 1:00 p.m. (Dallas, Texas time) on the date requested,
and the Borrower hereby irrevocably instructs SG to apply the proceeds of
such Mandatory Revolving Borrowing to the payment of the outstanding
Swingline Advances.

Section II.2 Method of Borrowing.

(1) Notice. Each Revolving Borrowing shall be made pursuant
to a Notice of Borrowing, given not later than (i) 11:00 a.m. (Dallas, Texas
time) on the third Business Day before the date of the proposed Borrowing, in
the case of a Eurodollar Rate Advance or

-21-
<PAGE> 28
(ii) 11:00 a.m. (Dallas, Texas time) on the Business Day of the proposed
Borrowing, in the case of a Prime Rate Advance, by the Borrower to the Agent,
which shall give to each Bank prompt notice on the day of receipt of timely
Notice of Borrowing of such proposed Borrowing by telecopier; provided however
that the Agent and each of the Banks hereby waive the requirement in subsection
(i) of this Section 2.2(a) that the Borrower provide three Business Days
advance written notice of the date of the initial Borrowing. Each Swingline
Advance shall be made pursuant to a Notice of Borrowing, given not later than
11:00 a.m. (Dallas, Texas time) on the day of the proposed Borrowing. Each
Notice of Borrowing shall be in writing or by telecopier specifying the
requested (a) date of such Borrowing, (b) Type of Advances comprising such
Borrowing, (c) aggregate amount of such Borrowing, and (d) if such Borrowing is
to be comprised of Eurodollar Rate Advances, the Interest Period for each such
Advance. In the case of a proposed Borrowing comprised of Eurodollar Rate
Advances, the Agent shall promptly notify each Bank of the applicable interest
rate under Section 2.6(b). Each Bank shall (1) in the case of all Revolving
Borrowings other than Borrowings made on the same day as the day the Notice of
Borrowing is received, before 11:00 a.m. (Dallas, Texas time) on the date of
such Borrowing and (2) in the case of Revolving Borrowings made on the same day
as the date of the Notice of Borrowing or Mandatory Revolving Borrowings,
before 1:00 p.m. (Dallas, Texas time), make available for the account of its
Applicable Lending Office to the Agent at its address referred to in Section
9.2, or such other location as the Agent may specify by notice to the Banks, in
same day funds, such Bank's Pro Rata Share of such Borrowing. After the
Agent's receipt of such funds and upon fulfillment of the applicable conditions
set forth in Article III, the Agent will make such funds available to the
Borrower at its account with the Agent.

(2) Conversions and Continuations. In order to elect to
Convert or continue Advances comprising part of the same Revolving Borrowing
under this Section, the Borrower shall deliver an irrevocable Notice of
Conversion or Continuation to the Agent at the Agent's office no later than
11:00 a.m. (Dallas, Texas time) (i) on the Business Day of the proposed
conversion date in the case of a Conversion of such Advances to Prime Rate
Advances and (ii) at least three Business Days in advance of the proposed
Conversion or continuation date in the case of a Conversion to, or a
continuation of, Eurodollar Rate Advances. Each such Notice of Conversion or
Continuation shall be in writing or by telecopier, specifying (a) the requested
Conversion or continuation date (which shall be a Business Day), (b) the
Borrowing amount and Type of the Advances to be Converted or continued, (c)
whether a Conversion or continuation is requested, and if a Conversion, into
what Type of Advances, and (d) in the case of a Conversion to, or a
continuation of, Eurodollar Rate Advances, the requested Interest Period.
Revolving Advances may only be Converted or continued as Revolving Advances.
Swingline Advances may not be converted or continued. Promptly after receipt
of a Notice of Conversion or Continuation under this paragraph, the Agent shall
provide each Bank with a copy thereof and, in the case of a Conversion to or a
Continuation of Eurodollar Rate Advances, notify each Bank of the applicable
interest rate under Section 2.6(b). For purposes other than the conditions set
forth in Section 3.2, the portion of Revolving Advances comprising part of the
same Revolving Borrowing that are Converted to Revolving Advances of another
Type shall constitute a new Revolving Borrowing.

(3) Certain Limitations. Notwithstanding anything in
paragraphs (a) and (b) above:

-22-
<PAGE> 29
(1) each Borrowing (other than a Borrowing
of Swingline Advances) shall be in an aggregate amount not less
than $2,000,000 or greater multiples of $1,000,000, in the case
of Eurodollar Rate Advances, or $1,000,000 or greater multiples
of $100,000, in the case of Prime Rate Advances, and shall
consist of Advances of the same Type made on the same day by the
Banks ratably according to their respective Commitments.

(2) at no time shall there be more than five
Interest Periods applicable to outstanding Eurodollar Rate
Advances;

(3) the Borrower may not select Eurodollar
Rate Advances for any Borrowing to be made, Converted or
continued if (A) the aggregate amount of such Borrowing is less
than $2,000,000 or (B) a Default has occurred and is continuing;

(4) (A) if any Bank shall, at any time prior
to the making of any requested Borrowing comprised of Eurodollar
Rate Advances, notify the Agent that the introduction of or any
change in or in the interpretation of any law or regulation makes
it unlawful, or that any central bank or other governmental
authority asserts that it is unlawful, for such Bank or its
Eurodollar Lending Office to perform its obligations under this
Agreement to make Eurodollar Rate Advances or to fund or maintain
Eurodollar Rate Advances, such Bank's Pro Rata Share of such
Borrowing shall be made as a Prime Rate Advance of such Bank, but
otherwise shall be considered part of the same Borrowing and
interest on such Prime Rate Advance shall be due and payable at
the same time that interest on the Eurodollar Rate Advances
comprising the remainder of such Borrowing shall be due and
payable; and (B) such Bank agrees to use commercially reasonable
efforts (consistent with its internal policies and legal and
regulatory restrictions) to designate a different Applicable
Lending Office if the making of such designation would avoid the
effect of this paragraph and would not, in the reasonable
judgment of such Bank, be otherwise disadvantageous to such Bank;

(5) if the Agent is unable to determine the
Eurodollar Rate for Eurodollar Rate Advances comprising any
requested Borrowing, the right of the Borrower to select
Eurodollar Rate Advances for such Borrowing or for any subsequent
Borrowing shall be suspended until the Agent shall notify the
Borrower and the Banks that the circumstances causing such
suspension no longer exist, and each Advance comprising such
Borrowing shall be a Prime Rate Advance;

(6) if the Majority Banks shall, at least
one Business Day before the date of any requested Borrowing,
notify the Agent that the Eurodollar Rate for Eurodollar Rate
Advances comprising such Borrowing will not adequately reflect
the cost to such Banks of making or funding their respective
Eurodollar Rate Advances, as the case may be, for such Borrowing,
the right of the Borrower to select

-23-
<PAGE> 30
Eurodollar Rate Advances for such Borrowing or for any subsequent
Borrowing shall be suspended until the Agent shall notify the
Borrower and the Banks that the circumstances causing such
suspension no longer exist, and each Advance comprising such
Borrowing shall be a Prime Rate Advance; and

(7) if the Borrower shall fail to select the
duration or continuation of any Interest Period for any
Eurodollar Rate Advances in accordance with the provisions
contained in the definition of "Interest Period" in Section 1.1
and paragraph (a) or (b) above, the Agent will forthwith so
notify the Borrower and the Banks and such Advances will be made
available to the Borrower on the date of such Borrowing as Prime
Rate Advances or, if an existing Advance, Converted into Prime
Rate Advances.

(4) Notices Irrevocable. Each Notice of Borrowing and Notice
of Conversion or Continuation shall be irrevocable and binding on the Borrower.
In the case of any Borrowing which the related Notice of Borrowing specifies is
to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each
Bank against any loss, out-of-pocket cost or expense incurred by such Bank as a
result of any condition precedent for Borrowing set forth in Article III not
being satisfied for any reason, including, without limitation, any loss, cost
or expense actually incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by such Bank to fund the Advance to be made by
such Bank as part of such Borrowing when such Advance, as a result of such
failure, is not made on such date.

(5) Agent Reliance. Unless the Agent shall have received
notice from a Bank before the date of any Revolving Borrowing or Mandatory
Revolving Borrowing that such Bank will not make available to the Agent such
Bank's Pro Rata Share of the Borrowing, the Agent may assume that such Bank has
made its Pro Rata Share of such Borrowing available to the Agent on the date of
such Borrowing in accordance with paragraph (a) of this Section 2.2 and the
Agent may, in reliance upon such assumption, make available to the Borrower on
such date a corresponding amount. If and to the extent that such Bank shall
not have so made its Pro Rata Share of such Borrowing available to the Agent,
such Bank and the Borrower severally agree to immediately repay to the Agent on
demand such corresponding amount, together with interest on such amount, for
each day from the date such amount is made available to the Borrower until the
date such amount is repaid to the Agent, at (i) in the case of the Borrower,
the interest rate applicable on such day to Advances comprising such Borrowing
and (ii) in the case of such Bank, the Federal Funds Rate for such day. If
such Bank shall repay to the Agent such corresponding amount and interest as
provided above, such corresponding amount so repaid shall constitute such
Bank's Advance as part of such Borrowing for purposes of this Agreement even
though not made on the same day as the other Advances comprising such
Borrowing.

(6) Bank Obligations Several. The failure of any Bank to
make the Advance to be made by it as part of any Borrowing shall not relieve
any other Bank of its obligation, if any, to make its Advance on the date of
such Borrowing. No Bank shall be responsible for the failure of any other Bank
to make the Advance to be made by such other Bank on the date of any Borrowing.

-24-
<PAGE> 31
(7) Notes. The indebtedness of the Borrower to each Bank

resulting from Swingline Advances owing to SG shall be evidenced by the

the Effective Date until the Maturity Date, such fees due and payable quarterly
in arrears on the last Business Day of each March, June, September and December

last Business Day of each March, June, September and December and (ii) on the
Maturity Date. In addition, the Borrower agrees to pay to each Issuing Bank
for its own account fees in respect of all Letters of Credit outstanding and

maximum amount available from time to time to be drawn under such outstanding
Letters of Credit, payable in arrears on the last Business Day of each March,
June, September and December and on the Maturity Date.

(3) Agent Fees. The Borrower agrees to pay to the Agent for
its benefit the fees set forth in the Agent's Fee Letter.

(1) Voluntary Reduction. The Borrower shall have the right,
upon at least three Business Days' irrevocable notice to the Agent, to
terminate in whole or reduce ratably in part the unused portion of the
Revolving Commitments; provided that each partial reduction shall be in the
aggregate amount of $1,000,000 or an integral multiple of $1,000,000. Any
reduction or termination of the Revolving Commitments pursuant to this Section
2.4 shall be permanent, with no obligation of the Banks to reinstate such
Revolving Commitments and the commitment fees provided for in Section 2.3(a)
shall thereafter be computed on the basis of the Revolving Commitments, as so
reduced.

-25-
<PAGE> 32
(2) Change of Control. Upon the occurrence of any of the
following:

(i) a change in control is reported by the Borrower in response
to either Item 6(e) of Schedule 14A of Regulation 14A promulgated
under the Securities Exchange Act of 1934 (the "Exchange Act"),
or (ii) any "person" (as such term is used in Section 13(d) and
Section 14(d)(2) of the Exchange Act) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange
Act), directly or indirectly, of securities of the Borrower
representing the Control Percentage or more of the combined
voting power of the Borrower's then outstanding securities;
then, in such event the Majority Banks may, at their sole option
upon written notice to the Borrower (a "Termination Notice"),
declare the obligation of each Bank to make Advances and the
obligation of each Issuing Bank to issue, increase, or extend
Letters of Credit to be terminated, whereupon the same shall
forthwith terminate and the Revolving Commitments shall reduce to
zero.

Section II.5 Repayment of Advances.

(1) Revolving Advances. The Borrower shall repay the
outstanding principal amount of each Revolving Advance on the Maturity Date.

(2) Swingline Advances. The Borrower shall repay the
outstanding principal amount of each Swingline Advance on the earlier of the
Maturity Date or the date which is three Business Days after the date such
Swingline Advance was made.

Section II.6 Interest. The Borrower shall pay interest on the unpaid
principal amount of each Advance from the date of such Advance until such
principal amount shall be paid in full, at the following rates per annum:

(1) Prime Rate Advances. If such Advance is a Prime Rate
Advance, a rate per annum equal at all times to the lesser of (i) the Adjusted
Prime Rate in effect from time to time plus the Applicable Margin and (ii) the
Maximum Rate, payable in arrears on the last Business Day of each calendar
quarter and on the date such Prime Rate Advance shall be paid in full, provided
that any amount of principal which is not paid when due (whether at stated
maturity, by acceleration or otherwise) shall bear interest from the date on
which such amount is due until such amount is paid in full, payable on demand,
at a rate per annum equal at all times to the lesser of (a) the rate required
to be paid on such Advance immediately prior to the date on which such amount
becomes due plus two percent (2%) and (b) the Maximum Rate.

(2) Eurodollar Rate Advances. If such Advance is a
Eurodollar Rate Advance, a rate per annum equal at all times during the
Interest Period for such Advance to the lesser of (i) the Eurodollar Rate for
such Interest Period plus the Applicable Margin and (ii) the Maximum Rate,
payable in arrears on the last day of such Interest Period, and on the date
such Eurodollar Rate Advance shall be paid in full; provided that any amount of
principal which is not paid when due (whether at stated maturity, by
acceleration or otherwise) shall bear interest from the date on which such
amount is due until such amount is paid in full, payable on demand, at a rate
per annum equal at all times to the lesser of (A) the greater of (1) the
Adjusted Prime Rate in effect from time to time plus two percent (2%) and (2)
the rate required to be paid on such Advance immediately prior to the date on
which such amount became due plus two percent (2%) and (B) the Maximum Rate.

-26-
<PAGE> 33
(3) Swingline Advances. If such Advance is a Swingline
Advance, a rate per annum equal at all times to the lesser of (i) the rate
agreed to pursuant to the Letter Agreement dated as of April 17, 1998 between
SG and the Borrower and (ii) the Maximum Rate, payable in arrears on the date
such Advance shall be paid in full, provided that any amount of principal which
is not paid when due (whether at stated maturity, by acceleration or otherwise)
shall bear interest from the date on which such amount is due until such amount
is paid in full, payable on demand, at a rate per annum equal at all times to
the lesser of (A) the rate required to be paid on such Advance immediately
prior to the date on which such amount becomes due plus two percent (2%) and
(B) the Maximum Rate.

(4) Usury Recapture. In the event the rate of interest
chargeable under this Agreement or the Notes at any time is greater than the
Maximum Rate, the unpaid principal amount of the Notes shall bear interest at
the Maximum Rate until the total amount of interest paid or accrued on the
Notes equals the amount of interest which would have been paid or accrued on
the Notes if the stated rates of interest set forth in this Agreement had at
all times been in effect. In the event, upon payment in full of the Notes, the
total amount of interest paid or accrued under the terms of this Agreement and
the Notes is less than the total amount of interest which would have been paid
or accrued if the rates of interest set forth in this Agreement had, at all
times, been in effect, then the Borrower shall, to the extent permitted by
applicable law, pay the Agent for the account of the Banks an amount equal to
the difference between (i) the lesser of (A) the amount of interest which would
have been charged on the Notes if the Maximum Rate had, at all times, been in
effect and (B) the amount of interest which would have accrued on the Notes if
the rates of interest set forth in this Agreement had at all times been in
effect and (ii) the amount of interest actually paid or accrued under this
Agreement on the Notes. In the event the Banks ever receive, collect or apply
as interest any sum in excess of the Maximum Rate, such excess amount shall, to
the extent permitted by law, be applied to the reduction of the principal
balance of the Notes, and if no such principal is then outstanding, such excess
or part thereof remaining shall be paid to the Borrower.

(5) Other Amounts Overdue. If any amount payable under this
Agreement other than the Advances is not paid when due and payable, including
without limitation, accrued interest and fees, then such overdue amount shall
accrue interest hereon due and payable on demand at a rate per annum equal to
the Adjusted Prime Rate plus two percent (2%), from the date such amount became
due until the date such amount is paid in full.

Section II.7 Prepayments.

(1) Right to Prepay. The Borrower shall have no right to
prepay any principal amount of any Advance except as provided in this Section
2.7.

(2) Optional Prepayments. The Borrower may elect to prepay
any of the Advances, after giving notice thereof to the Agent (i) by 11:00 a.m.
(Dallas, Texas time) on the day of prepayment of any Swingline Advance, and
(ii) by 11:00 a.m. (Dallas Texas time) at least

-27-
<PAGE> 34
three Business Days' prior to the day of prepayment of any Eurodollar Rate
Advances, and at least one Business Day prior to the day of prepayment of any
Prime Rate Advances. Such notice must state the proposed date and aggregate
principal amount of such prepayment, whether such prepayment should be applied
to reduce outstanding Revolving Advances or Swingline Advances, and if
applicable, the relevant Interest Period for the Advances to be prepaid. If
any such notice is given, the Borrower shall prepay Advances comprising part of
the same Borrowing in whole or ratably in part in an aggregate principal amount
equal to the amount specified in such notice, and shall also pay accrued
interest to the date of such prepayment on the principal amount prepaid and
amounts, if any, required to be paid pursuant to Section 2.8 as a result of
such prepayment being made on such date; provided, however, that each partial
prepayment of Eurodollar Rate Advances shall be in an aggregate principal
amount not less than $1,000,000 or an integral multiple of $1,000,000.

(3) Mandatory Prepayments.

(1) Change of Control. On the fifth Business Day
following the Borrower's receipt of a Termination Notice pursuant to
Section 2.4(b) hereof, the Borrower shall be required to prepay all
outstanding Advances in full and to deposit with the Agent into the Cash
Collateral Account an amount equal to the Letter of Credit Exposure.

(2) Borrowing Base Deficiency. On each Borrowing
Base Determination Date, the Borrower shall be required to prepay the
Advances in an aggregate amount equal to the excess of (A) the aggregate
amount of outstanding Advances and Letter of Credit Exposure on such date
over (B) the Borrowing Base, as determined on such Borrowing Base
Determination Date (or, upon payment in full of all outstanding Advances,
to deposit with the Agent into the Cash Collateral Account an amount equal
to the amount of the Letter of Credit Exposure which exceeds the Borrowing
Base).

(3) Reduction of Revolving Commitments. In the
event the Revolving Commitments are reduced in accordance with Section
2.4(a), the Borrower shall prepay the Advances to the extent the
outstanding Advances plus the Letter of Credit Exposure exceed the reduced
Revolving Commitments (or, upon payment in full of all outstanding
Advances, to deposit with the Agent into the Cash Collateral Account an
amount equal to the amount of the Letter of Credit Exposure which exceeds
the Revolving Commitments as so reduced).

(4) Accrued Interest. Each prepayment pursuant to
this Section 2.7(c) shall be accompanied by accrued interest on the amount
prepaid to the date of such prepayment and amounts, if any, required to be
paid pursuant to Section 2.8 as a result of such prepayment being made on
such date.

(5) Avoidance of Breakage Costs. In the event that
the amount of any mandatory prepayment of Advances under this Section
2.7(c) exceeds the aggregate principal amount of Advances which consist of
Prime Rate Advances (the amount of such excess being the "Excess Amount"),
the Borrower shall have the right, in lieu of making such prepayment in
full, to prepay such outstanding Advances which are Prime Rate

-28-
<PAGE> 35
Advances and to deposit an amount equal to the Excess Amount with the
Agent in the Cash Collateral Account maintained by and in the sole
dominion and control of the Agent for the ratable benefit of the Banks.
Any amount so deposited shall be held by the Agent as collateral for the
Obligations and applied to the prepayment of Advances which are Eurodollar
Rate Advances at the end of the current Interest Period(s) applicable
thereto. On any day on which amounts collected in the Cash Collateral
Account remain on deposit in or to the credit of the Cash Collateral
Account after giving effect to the payment made on such day pursuant to
this Section 2.7(c), and the Borrower shall have delivered to the Agent a
written request or a telephonic request (which shall be promptly confirmed
in writing) prior to 10:00 am (Dallas, Texas time) that such remaining
collected amounts be invested in cash equivalents specified in such
request, the Agent shall invest such funds, to the extent the Agent is
reasonably able to do so, in such cash equivalents as are acceptable to,
and with no risk to, the Agent on an overnight basis or with maturities
such that amounts will be available to pay the Obligations secured thereby
as they become due, whether at maturity, by acceleration or otherwise;
provided, however, that any loss resulting from such investments shall be
charged to and be immediately payable by the Borrower on demand by the
Agent.

(4) Ratable Payments. Each payment of any Advance pursuant
to this Section 2.7 or any other provision of this Agreement shall be made in a
manner such that all Advances comprising part of the same Borrowing are paid in
whole or ratably in part.

(5) Effect of Notice. All notices given pursuant to this
Section 2.7 shall be irrevocable and binding upon the Borrower.

Section II.8 Breakage Costs. If (a) any payment of principal of any
Eurodollar Rate Advance is made other than on the last day of the Interest
Period for such Advance as a result of any payment pursuant to Section 2.7 or
the acceleration of the maturity of the Notes pursuant to Article VIII or
otherwise; (b) any Conversion of a Eurodollar Rate Advance is made other than
on the last day of the Interest Period for such Advance pursuant to Section
2.12 or otherwise; or (c) the Borrower fails to make a principal or interest
payment with respect to any Eurodollar Rate Advance on the date such payment is
due and payable, the Borrower shall, within 10 days of any written demand sent
by any Bank to the Borrower through the Agent, pay to the Agent for the account
of such Bank any amounts (without duplication of any other amounts payable in
respect of breakage costs) required to compensate such Bank for any additional
losses, out-of-pocket costs or expenses which it may reasonably incur as a
result of such payment or nonpayment, including, without limitation, any loss
(including loss of anticipated profits), cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by any Bank
to fund or maintain such Advance.

Section II.9 Increased Costs.

(1) Eurodollar Rate Advances. If, due to either (i) the
introduction of or any change (other than any change by way of imposition or
increase of reserve requirements included in the calculation of the Eurodollar
Rate) in or in the interpretation of any law or regulation or (ii) the
compliance with any guideline or request from any central bank or other
Governmental

-29-
<PAGE> 36
Authority (whether or not having the force of law), there shall be any increase
in the cost to any Bank of agreeing to make or making, funding or maintaining
Eurodollar Rate Advances, then the Borrower shall from time to time, upon
demand by such Bank (with a copy of such demand to the Agent), immediately pay
to the Agent for the account of such Bank additional amounts (without
duplication of any other amounts payable in respect of increased costs)
sufficient to compensate such Bank for such increased cost; provided, however,
that, before making any such demand, each Bank agrees to use commercially
reasonable efforts (consistent with its internal policy and legal and
regulatory restrictions) to designate a different Applicable Lending Office if
the making of such a designation would avoid the need for, or reduce the amount
of, such increased cost and would not, in the reasonable judgment of such Bank,
be otherwise disadvantageous to such Bank. A certificate as to the amount of
such increased cost and detailing the calculation of such cost submitted to the
Borrower and the Agent by such Bank at the time such Bank demands payment under
this Section shall be conclusive and binding for all purposes, absent manifest
error.

(2) Capital Adequacy. If any Bank or any Issuing Bank
determines in good faith that compliance with any law or regulation or any
guideline or request from any central bank or other governmental authority
(whether or not having the force of law) implemented or effective after the
date of this Agreement affects or would affect the amount of capital required
or expected to be maintained by such Bank or such Issuing Bank and that the
amount of such capital is increased by or based upon the existence of such
Bank's commitment to lend or such Issuing Bank's commitment to issue Letters of
Credit or any Bank's commitment to risk participate in Letters of Credit and
other commitments of this type, then, upon 30 days prior written notice by such
Bank or such Issuing Bank (with a copy of any such demand to the Agent), the
Borrower shall immediately pay to the Agent for the account of such Bank or to
such Issuing Bank, as the case may be, from time to time as specified by such
Bank or such Issuing Bank, additional amounts (without duplication of any other
amounts payable in respect of increased costs) sufficient to compensate such
Bank or such Issuing Bank, in light of such circumstances, (i) with respect to
such Bank, to the extent that such Bank reasonably determines such increase in
capital to be allocable to the existence of such Bank's commitment to lend
under this Agreement or its commitment to risk participate in Letters of Credit
and (ii) with respect to such Issuing Bank, to the extent that such Issuing
Bank reasonably determines such increase in capital to be allocable to the
issuance or maintenance of the Letters of Credit. A certificate as to such
amounts and detailing the calculation of such amounts submitted to the Borrower
by such Bank or such Issuing Bank shall be conclusive and binding for all
purposes, absent manifest error.

(3) Letters of Credit. If any change in any law or
regulation or in the interpretation thereof by any court or administrative or
Governmental Authority charged with the administration thereof shall either (i)
impose, modify, or deem applicable any reserve, special deposit, or similar
requirement against letters of credit issued by, or assets held by, or deposits
in or for the account of, any Issuing Bank or any Bank or (ii) impose on such
Issuing Bank or any Bank any other condition regarding the provisions of this
Agreement relating to the Letters of Credit or any Letter of Credit
Obligations, and the result of any event referred to in the preceding clause
(i) or (ii) shall be to increase the cost to such Issuing Bank of issuing or
maintaining any Letter of Credit, or increase the cost to such Bank of its risk
participation in any Letter of Credit

-30-
<PAGE> 37
(which increase in cost shall be determined by such Issuing Bank's or such
Bank's reasonable allocation of the aggregate of such cost increases resulting
from such event), then, upon demand by such Issuing Bank or such Bank (with a
copy sent to the Agent), as the case may be, the Borrower shall pay to the
Agent (for the account of such Issuing Bank), as the case may be, from time to
time as specified by such Issuing Bank or such Bank, additional amounts which
shall be sufficient to compensate such Issuing Bank or such Bank for such
increased cost. Each Issuing Bank and each Bank agrees to use commercially
reasonable efforts (consistent with internal policy and legal and regulatory
restrictions) to designate a different Applicable Lending Office for the
booking of its Letters of Credit or risk participations if the making of such
designation would avoid the effect of this paragraph and would not, in the
reasonable judgment of such Issuing Bank or such Bank, be otherwise
disadvantageous to such Issuing Bank or such Bank, as the case may be. A
certificate as to such increased cost incurred by such Issuing Bank or such
Bank, as the case may be, as a result of any event mentioned in clause (i) or
(ii) above, and detailing the calculation of such increased costs submitted by
such Issuing Bank or such Bank to the Borrower, shall be conclusive and binding
for all purposes, absent manifest error.

Section II.10 Payments and Computations.

(1) Payment Procedures. Except if otherwise set forth
herein, the Borrower shall make each payment under this Agreement and under the
Notes not later than 11:00 a.m. (Dallas, Texas time) on the day when due in
Dollars to the Agent at the location referred to in the Notes (or such other
location as the Agent shall designate in writing to the Borrower) in same day
funds. The Agent will promptly thereafter cause to be distributed like funds
relating to the payment of principal, interest or fees ratably (other than
amounts payable solely to the Agent, the Issuing Banks, or a specific Bank
pursuant to Section 2.1(b), 2.3(b), 2.3(c), 2.6(c), 2.8, 2.9, 2.11, 2.12, or
2.13(c) but after taking into account payments effected pursuant to Section
9.4) to the Banks in accordance with each Bank's Pro Rata Share for the account
of their respective Applicable Lending Offices, and like funds relating to the
payment of any other amount payable to any Bank or any Issuing Bank to such
Bank or such Issuing Bank for the account of its Applicable Lending Office, in
each case to be applied in accordance with the terms of this Agreement.

(2) Computations. All computations of interest based on the
Adjusted Prime Rate shall be made by the Agent on the basis of a year of 365 or
366 days, as the case may be, and all computations of fees and interest based
on the Eurodollar Rate and the Federal Funds Rate shall be made by the Agent on
the basis of a year of 360 days, in each case for the actual number of days
(including the first day, but excluding the last day) occurring in the period
for which such interest or fees are payable. Each determination by the Agent
of an interest rate shall be conclusive and binding for all purposes, absent
manifest error.

(3) Non-Business Day Payments. Whenever any payment shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of payment of interest or fees, as the case
may be; provided, however, that if such extension would cause payment of
interest on or principal of Eurodollar Rate Advances to be made in the next
following calendar month, such payment shall be made on the next preceding
Business Day.

-31-
<PAGE> 38
(4) Agent Reliance. Unless the Agent shall have received
written notice from the Borrower prior to the date on which any payment is due
to the Banks that the Borrower will not make such payment in full, the Agent
may assume that the Borrower has made such payment in full to the Agent on such
date and the Agent may, in reliance upon such assumption, cause to be
distributed to each Bank on such date an amount equal to the amount then due
such Bank. If and to the extent the Borrower shall not have so made such
payment in full to the Agent, each Bank shall repay to the Agent forthwith on
demand such amount distributed to such Bank, together with interest, for each
day from the date such amount is distributed to such Bank until the date such
Bank repays such amount to the Agent, at the Federal Funds Rate for such day.

(5) Application of Payments. Unless otherwise specified in
Section 2.7 hereof, whenever any payment received by the Agent under this
Agreement is insufficient to pay in full all amounts then due and payable under
this Agreement and the Notes, such payment shall be distributed and applied by
the Agent and the Banks in the following order: first, to the payment of fees
and expenses due and payable to the Agent under and in connection with this
Agreement or any other Credit Document; second, to the payment of all expenses
due and payable under Section 2.11(c), ratably among the Banks in accordance
with the aggregate amount of such payments owed to each such Bank; third, to
the payment of fees due and payable to the Issuing Banks pursuant to Section
2.3(b); fourth, to the payment of all other fees due and payable under Section
2.3 ratably among the Banks in accordance with their applicable Commitments;
and fifth, to the payment of the interest accrued on and the principal amount
of all of the Notes and the interest accrued on and all Reimbursement
Obligations, regardless of whether any such amount is then due and payable,
ratably among the Banks in accordance with the aggregate accrued interest plus
the aggregate principal amount owed to such Bank.

Section II.11 Taxes.

(1) No Deduction for Certain Taxes. Any and all payments by
the Borrower shall be made, in accordance with Section 2.10, free and clear of
and without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
excluding, in the case of each Bank, each Issuing Bank, and the Agent, taxes
imposed on its income, and franchise taxes imposed on it, by the jurisdiction
under the laws of which such Bank, such Issuing Bank, or the Agent (as the case
may be) is organized or any political subdivision of the jurisdiction (all such
nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes") and, in the case of each
Bank and each Issuing Bank, Taxes by the jurisdiction of such Bank's Applicable
Lending Office or any political subdivision of such jurisdiction. If the
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable to any Bank, any Issuing Bank, or the Agent, (i) the sum payable
shall be increased as may be necessary so that, after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.11), such Bank, such Issuing Bank, or the Agent (as the case may
be) receives an amount equal to the sum it would have received had no such
deductions been made; provided, however, that if the Borrower's obligation to
deduct or withhold Taxes is caused solely by such

-32-
<PAGE> 39
Bank's, such Issuing Bank's, or the Agent's failure to provide the forms
described in paragraph (e) of this Section 2.11 and such Bank, such Issuing
Bank, or the Agent could have provided such forms, no such increase shall be
required; (ii) the Borrower shall make such deductions; and (iii) the Borrower
shall pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law.

(2) Other Taxes. In addition, the Borrower agrees to pay any
present or future stamp or documentary taxes or any other excise or property
taxes, charges or similar levies which arise from any payment made or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement, the Notes, or the other Credit Documents (hereinafter referred to as
"Other Taxes").

(3) Indemnification. The Borrower indemnifies each Bank,
each Issuing Bank, and the Agent for the full amount of Taxes or Other Taxes
(including, without limitation, any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section 2.11) paid by such Bank,
such Issuing Bank, or the Agent (as the case may be) and any liability
(including interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted.
Each payment required to be made by the Borrower in respect of this
indemnification shall be made to the Agent for the benefit of any party
claiming such indemnification within 30 days from the date the Borrower
receives written demand detailing the calculation of such amounts therefor from
the Agent on behalf of itself as Agent, any Issuing Bank, or any such Bank. If
any Bank, the Agent, or any Issuing Bank receives a refund in respect of any
taxes paid by the Borrower under this paragraph (c), such Bank, the Agent, or
such Issuing Bank, as the case may be, shall promptly pay to the Borrower the
Borrower's share of such refund.

(4) Evidence of Tax Payments. The Borrower will pay prior to
delinquency all Taxes payable in respect of any payment. Within 30 days after
the date of any payment of Taxes, the Borrower will furnish to the Agent, at
its address referred to in Section 9.2, the original or a certified copy of a
receipt evidencing payment of such Taxes.

(5) Foreign Bank Withholding Exemption. Each Bank and each
Issuing Bank that is not incorporated under the laws of the United States of
America or a state thereof agrees that it will deliver to the Borrower and the
Agent on the date of this Agreement or upon the effectiveness of any Assignment
and Acceptance (i) two duly completed copies of United States Internal Revenue
Service Form 1001 or 4224 or successor applicable form, as the case may be,
certifying in each case that such Bank is entitled to receive payments under
this Agreement and the Notes payable to it, without deduction or withholding of
any United States federal income taxes, (ii) if applicable, an Internal Revenue
Service Form W-8 or W-9 or successor applicable form, as the case may be, to
establish an exemption from United States backup withholding tax, and (iii) any
other governmental forms which are necessary or required under an applicable
tax treaty or otherwise by law to reduce or eliminate any withholding tax,
which have been reasonably requested by the Borrower. Each Bank which delivers
to the Borrower and the Agent a Form 1001 or 4224 and Form W-8 or W-9 pursuant
to the next preceding sentence further undertakes to deliver to the Borrower
and the Agent two further copies of Form 1001 or 4224

-33-
<PAGE> 40
and Form W-8 or W-9, or successor applicable forms, or other manner of
certification, as the case may be, on or before the date that any such form
expires or becomes obsolete or after the occurrence of any event requiring a
change in the most recent form previously delivered by it to the Borrower and
the Agent, and such extensions or renewals thereof as may reasonably be
requested by the Borrower and the Agent certifying in the case of a Form 1001
or 4224 that such Bank is entitled to receive payments under this Agreement
without deduction or withholding of any United States federal income taxes. If
an event (including without limitation any change in treaty, law or regulation)
has occurred prior to the date on which any delivery required by the preceding
sentence would otherwise be required which renders all such forms inapplicable
or which would prevent any Bank from duly completing and delivering any such
letter or form with respect to it and such Bank advises the Borrower and the
Agent that it is not capable of receiving payments without any deduction or
withholding of United States federal income tax, and in the case of a Form W-8
or W-9, establishing an exemption from United States backup withholding tax,
such Bank shall not be required to deliver such forms. The Borrower shall
withhold tax at the rate and in the manner required by the laws of the United
States with respect to payments made to a Bank failing to timely provide the
requisite Internal Revenue Service forms.

Section II.12 Illegality. If any Bank shall notify the Agent and the
Borrower that the introduction of or any change in or in the interpretation of
any law or regulation makes it unlawful, or that any central bank or other
Governmental Authority asserts that it is unlawful for such Bank or its
Eurodollar Lending Office to perform its obligations under this Agreement to
maintain any Eurodollar Rate Advances of such Bank then outstanding hereunder,
then, notwithstanding anything herein to the contrary, the Borrower shall, if
demanded by such Bank in its notice, no later than 11:00 a.m. (Dallas, Texas
time), (a) if not prohibited by law or regulation to maintain such Eurodollar
Rate Advances for the duration of the Interest Period, on the last day of the
Interest Period for each outstanding Eurodollar Rate Advance of such Bank or
(b) if prohibited by law or regulation to maintain such Eurodollar Rate
Advances for the duration of the Interest Period, on the second Business Day
following its receipt of such notice from such Bank, Convert all Eurodollar
Rate Advances of such Bank then outstanding to Prime Rate Advances, and pay
accrued interest on the principal amount Converted to the date of such
Conversion and amounts, if any, required to be paid pursuant to Section 2.8 as
a result of such Conversion being made on such date. Each Bank agrees to use
commercially reasonable efforts (consistent with its internal policies and
legal and regulatory restrictions) to designate a different Applicable Lending
Office if the making of such designation would avoid the effect of this
paragraph and would not, in the reasonable judgment of such Bank, be otherwise
disadvantageous to such Bank.

Section II.13 Letters of Credit.

(1) Issuance. From time to time from the date of this
Agreement until three months before the Maturity Date, at the request of the
Borrower, each Issuing Bank shall, on any Business Day and on the terms and
conditions hereinafter set forth, issue, increase, decrease, amend, or extend
the expiration date of Letters of Credit for the account of the Borrower (for
its own benefit or for the benefit of any of its Subsidiaries). No Letter of
Credit will be issued, increased, or extended (i) if such issuance, increase,
or extension would cause the

-34-
<PAGE> 41
Letter of Credit Exposure to exceed the lesser of (A) $75,000,000 or (B) an
amount equal to (1) the lesser of the Borrowing Base or the aggregate Revolving
Commitments less (2) the aggregate outstanding Revolving Advances, Swingline
Advances and Letter of Credit Exposure at such time; (ii) unless such Letter of
Credit has an Expiration Date not later than the earlier of (A) one year after
the date of issuance thereof and (B) five days before the Maturity Date; (iii)
unless such Letter of Credit is in form and substance acceptable to the
respective Issuing Bank in its sole discretion; (iv) unless such Letter of
Credit is a standby letter of credit not supporting the repayment of
indebtedness for borrowed money of any Person, other than a Letter of Credit
issued in substitution of any letter of credit outstanding on the Effective
Date and listed on Schedule 1.1(b); (v) unless the Borrower has delivered to
the respective Issuing Bank a completed and executed letter of credit
application on such Issuing Bank's standard form, which shall contain terms no
more restrictive than the terms of this Agreement; and (vi) unless such Letter
of Credit is governed by the Uniform Customs and Practice for Documentary
Credits (1993 Revision), International Chamber of Commerce Publication No. 500
("UCP") or any successor to the UCP. If the terms of any letter of credit
application referred to in the foregoing clause (v) conflicts with the terms of
this Agreement, the terms of this Agreement shall control.

(2) Participations. With respect to each Letter of Credit
described on Schedule 1.1(b) which is outstanding on the Effective Date, each
Bank agrees that it has a participation in the related Letter of Credit
Exposure equal to such Bank's Pro Rata Share on the Effective Date. On the
date of the issuance or increase of any Letter of Credit on or after the
Effective Date, each Issuing Bank shall be deemed to have sold to each other
Bank and each other Bank shall have been deemed to have purchased from such
Issuing Bank a participation in the Letter of Credit Exposure related to the
Letters of Credit issued by such Issuing Bank equal to such Bank's Pro Rata
Share at such date and such sale and purchase shall otherwise be in accordance
with the terms of this Agreement. Each Issuing Bank shall promptly notify each
such participant Bank by telex, telephone, or telecopy of each Letter of Credit
of such Issuing Bank issued, increased or decreased, and the actual dollar
amount of such Bank's participation in such Letter of Credit. Each Bank's
obligation to purchase participating interests pursuant to this Section and to
reimburse the respective Issuing Bank for such Bank's Pro Rata Share of any
payment under a Letter of Credit by such Issuing Bank not reimbursed in full by
the Borrower shall be absolute and unconditional and shall not be affected by
any circumstance, including, without limitation, (i) any of the circumstances
described in paragraph (d) below, (ii) the occurrence and continuance of a
Default, (iii) an adverse change in the financial condition of the Borrower or
any Guarantor, or (iv) any other circumstance, happening or event whatsoever,
whether or not similar to any of the foregoing, except for any such
circumstance, happening or event constituting or arising from gross negligence
or willful misconduct on the part of such Issuing Bank.

(3) Reimbursement. The Borrower hereby agrees to pay on
demand to each Issuing Bank in respect of each Letter of Credit issued by such
Issuing Bank an amount equal to any amount paid by such Issuing Bank under or
in respect of such Letter of Credit. In the event any Issuing Bank makes a
payment pursuant to a request for draw presented under a Letter of Credit and
such payment is not promptly reimbursed by the Borrower upon demand, such
Issuing Bank shall give notice of such payment to the Agent and the Banks, and
each Bank shall promptly reimburse such Issuing Bank for such Bank's Pro Rata
Share of such payment, and such

-35-
<PAGE> 42
reimbursement shall be deemed for all purposes of this Agreement to constitute
a Prime Rate Advance to the Borrower from such Bank. If such reimbursement is
not made by any Bank to any Issuing Bank on the same day on which such Issuing
Bank shall have made payment on any such draw, such Bank shall pay interest
thereon to such Issuing Bank at a rate per annum equal to the Federal Funds
Rate. The Borrower hereby unconditionally and irrevocably authorizes,
empowers, and directs the Agent and the Banks to record and otherwise treat
each payment under a Letter of Credit not immediately reimbursed by the
Borrower as a Borrowing comprised of Prime Rate Advances to the Borrower.

(4) Obligations Unconditional. The obligations of the
Borrower under this Agreement in respect of each Letter of Credit shall be
unconditional and irrevocable, and shall be paid strictly in accordance with
the terms of this Agreement under all circumstances, notwithstanding the
following circumstances:

(1) any lack of validity or enforceability of any
Letter of Credit Documents;

(2) any amendment or waiver of or any consent to
departure from any Letter of Credit Documents;

(3) the existence of any claim, set-off, defense or
other right which the Borrower or any Bank or any other Person
may have at any time against any beneficiary or transferee of
such Letter of Credit (or any Persons for whom any such
beneficiary or any such transferee may be acting), the respective
Issuing Bank or any other Person or entity, whether in connection
with this Agreement, the transactions contemplated in this
Agreement or in any Letter of Credit Documents or any unrelated
transaction;

(4) any statement or any other document presented
under such Letter of Credit proving to be forged, fraudulent,
invalid or insufficient in any respect or any statement therein
being untrue or inaccurate in any respect to the extent the
respective Issuing Bank would not be liable therefor pursuant to
the following paragraph (e);

(5) payment by the respective Issuing Bank under
such Letter of Credit against presentation of a draft or
certificate which does not comply with the terms of such Letter
of Credit; or

(6) any other circumstance or happening whatsoever,
whether or not similar to any of the foregoing;

provided, however, that nothing contained in this paragraph (d) shall be deemed
to constitute a waiver of any remedies of the Borrower in connection with the
Letters of Credit.

-36-
<PAGE> 43
(5) Liability of Issuing Banks. The Borrower assumes all
risks of the acts or omissions of any beneficiary or transferee of any Letter
of Credit with respect to its use of such Letter of Credit. No Issuing Bank
nor any of its officers or directors shall be liable or responsible for:

(1) the use which may be made of any Letter of
Credit or any acts or omissions of any beneficiary or transferee
in connection therewith;

(2) the validity, sufficiency or genuineness of
documents, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient,
fraudulent or forged;

(3) payment by such Issuing Bank against
presentation of documents which do not comply with the terms of a
Letter of Credit, including failure of any documents to bear any
reference or adequate reference to the relevant Letter of Credit;
or

(4) any other circumstances whatsoever in making or
failing to make payment under any Letter of Credit (including
such Issuing Bank's own negligence),

except that the Borrower shall have a claim against such Issuing Bank, and such
Issuing Bank shall be liable to, and shall promptly pay to, the Borrower, to
the extent of any direct, as opposed to consequential, damages suffered by the
Borrower which the Borrower proves were caused by (A) such Issuing Bank's
willful misconduct or gross negligence in determining whether documents
presented under a Letter of Credit comply with the terms of such Letter of
Credit or (B) such Issuing Bank's willful failure to make lawful payment under
any Letter of Credit after the presentation to it of a draft and certificate
strictly complying with the terms and conditions of such Letter of Credit. In
furtherance and not in limitation of the foregoing, any Issuing Bank may accept
documents that appear on their face to be in order, without responsibility for
further investigation, regardless of any notice or information to the contrary.

Section II.14 Determination of Borrowing Base. The Borrowing Base
shall be determined by the Agent, as follows:

(1) Monthly. On the 25th day of each calendar month the
Agent shall determine the Borrowing Base upon receipt of a Borrowing Base
Certificate dated as of the last day of the immediately preceding calendar
month.

(2) Acceptable Security Interest. Each of the Eligible
Revenue Equipment, the Treadco Shares and the Eligible Receivables shall be
subject to an Acceptable Security Interest in favor of the Agent for the
benefit of the Banks until the Liens held by the Agent for the benefit of the
Banks upon the Collateral have been released pursuant to Section 2.17(f).

(3) Property Adjustments. Following (i) any sale by the
Borrower or any Guarantor of any Property included in the Borrowing Base with a
sales value in excess of $25,000,000 individually or in the aggregate since the
most recent month end, (ii) any loss or casualty not covered by insurance
resulting in destruction of any Property included in the

-37-
<PAGE> 44
Borrowing Base if the loss or casualty exceeds $25,000,000 individually or in
the aggregate since the most recent month end, and (iii) any permitted purchase
by the Borrower or any Guarantor of any Property which can be included in the
Borrowing Base with a purchase price in excess of $25,000,000 individually or
in the aggregate since the most recent month end (each of such events
hereinafter called an "Adjustment Event"), the Borrower shall (in the case of
(i) and (ii) above) or may (in the case of (iii) above) give the Agent notice
of such Adjustment Event within five Business Days of the closing of such
Adjustment Event, and the Agent may in its sole reasonable discretion (in the
case of (i) and (ii) above) or shall (in the case of (iii) above) further
adjust the appropriate Borrowing Base components set forth in the most recent
month end Borrowing Base Certificate delivered by the Borrower to the Banks to
reflect the Adjustment Events occurring since the date of such Borrowing Base
Certificate.

(4) Notice of Borrowing Base Change. Promptly following any
date the Borrowing Base is redetermined in accordance with the preceding
paragraphs, the Agent shall give notice to the Banks and the Borrower of the
new Borrowing Base.

Section II.15 Bank Replacement.

(1) Right to Replace. The Borrower shall have the right to
replace each Bank affected by a condition under Section 2.2(c)(iv), 2.9, or
2.12 for more than 90 days (each such affected Bank, an "Affected Bank") in
accordance with the procedures in this Section 2.15 and provided that no
reduction of the total Revolving Commitments occurs as a result thereof.

(2) First Right of Refusal; Replacement.

(1) Upon the occurrence of any condition permitting
the replacement of a Bank, each Bank which is not an Affected
Bank shall have the right, but not the obligation, to elect to
increase its respective Revolving Commitment by an amount not to
exceed the amount of the Revolving Commitments of the Affected
Banks, which election shall be made by written notice from each
such Bank to the Agent and the Borrower given within 30 days
after the date such condition occurs specifying the amount of
such proposed increase in such Bank's Revolving Commitment.

(2) If the aggregate amount of the proposed
increases in Revolving Commitments of all such Banks making such
an election is in excess of the Revolving Commitments of the
Affected Banks, (A) the Revolving Commitments of the Affected
Banks shall be allocated pro rata among such Banks based on the
respective amounts of the proposed increases to Revolving
Commitments elected by each of such Banks, and (B) the respective
Commitments of such Banks shall be increased by the respective
amounts as so allocated so that after giving effect to such
termination and increases the aggregate amount of the Revolving
Commitments of the Banks will be the same as prior to such
termination.

(3) If the aggregate amount of the proposed
increases to Revolving Commitments of all Banks making such an
election equals the Revolving

-38-
<PAGE> 45
Commitments of the Affected Banks, the respective Revolving
Commitments of such Banks shall be increased by the respective
amounts of their proposed increases, so that after giving effect
to such termination and increase the aggregate amount of the
Revolving Commitments of all of the Banks will be the same as
prior to such termination.

(4) If the aggregate amount of the proposed
increases to Revolving Commitments of all Banks making such an
election is less than the Revolving Commitments of the Affected
Banks, (A) the respective Revolving Commitments of such Banks
shall be increased by the respective amounts of their proposed
increases, and (B) the Borrower shall add additional Banks which
are Eligible Assignees to this Agreement to replace such Affected
Banks, which additional Banks would have aggregate Revolving
Commitments no greater than those of the Affected Banks minus the
amounts thereof assumed by the other Banks pursuant to such
increases.

(3) Procedure. Any assumptions of Revolving Commitments
pursuant to this Section 2.15 shall be (i) made by the purchasing Bank or
Eligible Assignee and the selling Bank entering into an Assignment and
Assumption and by following the procedures in Section 9.6 for adding a Bank.
In connection with the increase of the Revolving Commitments of any Bank
pursuant to the foregoing paragraph (b), each Bank with an increased Revolving
Commitment shall purchase from the Affected Banks at par such Bank's ratable
share of the outstanding Advances of the Affected Banks and assume such Bank's
ratable share of the Affected Banks' Letter of Credit Exposure.

Section II.16 Sharing of Payments, Etc. If any Bank shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off or otherwise) on account of its Advances or its share of Letter of
Credit Obligations in excess of its Pro Rata Share of payments on account of
the Advances or Letter of Credit Obligations obtained by all the Banks, such
Bank shall notify the Agent and forthwith purchase from the other Banks such
participations in the Advances made by them or Letter of Credit Obligations
held by them as shall be necessary to cause such purchasing Bank to share the
excess payment ratably in accordance with the requirements of this Agreement
with each of them; provided, however, that if all or any portion of such excess
payment is thereafter recovered from such purchasing Bank, such purchase from
each Bank shall be rescinded and such Bank shall repay to the purchasing Bank
the purchase price to the extent of such Bank's ratable share (according to the
proportion of (a) the amount of the participation sold by such Bank to the
purchasing Bank as a result of such excess payment to (b) the total amount of
such excess payment) of such recovery, together with an amount equal to such
Bank's ratable share (according to the proportion of (i) the amount of such
Bank's required repayment to the purchasing Bank to (ii) the total amount of
all such required repayments to the purchasing Bank) of any interest or other
amount paid or payable by the purchasing Bank in respect of the total amount so
recovered. The Borrower agrees that any Bank so purchasing a participation
from another Bank pursuant to this Section 2.16 may, to the fullest extent
permitted by law, unless and until rescinded as provided above, exercise all
its rights of payment (including the right of set-off) with respect to such
participation as fully as if such Bank were the direct creditor of the Borrower
in the amount of such participation.

sale of such Property, that no Default has occurred and is continuing on such
date or would result from the sale of such Property).

(6) Release of Collateral. If at any time, (a) either (i)

and by appropriate proceedings, or (vi) any other event or condition shall
occur or exist, with respect to a Plan; and in each case in clauses (i) through

Bank to issue, increase, or extend Letters of Credit to be terminated,
whereupon the same shall forthwith terminate, and (ii) shall at the request, or
may with the consent, of the Majority Banks, by notice to the Borrower, declare

waived by the Borrower, and

(2) the Borrower shall, on demand of the Agent at the request

Agreement in connection with the Letters of Credit.

(3) Duty of Care. The Agent shall exercise reasonable care
in the custody and preservation of any funds held in the Cash Collateral

the Agent accords its own property, it being understood that the Agent shall
not have any responsibility for taking any necessary steps to preserve rights
against any parties with respect to any such funds.

Section VII.5 Non-exclusivity of Remedies. No remedy conferred upon

(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Bank to or for the credit or the
account of the Borrower against any and all of the obligations of the Borrower
now or hereafter existing under this Agreement, the Note held by such Bank, and
the other Credit Documents, irrespective of whether or not such Bank shall have
made any demand under this Agreement, such Note, or such other Credit
Documents, and although such obligations may be unmatured. Each Bank agrees to
promptly notify the Borrower after any such set-off and application made by
such Bank, provided that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of each Bank under this
Section are in addition to any other rights and remedies (including, without

ARTICLE VIII

AGENCY AND ISSUING BANK PROVISIONS

Section VIII.1 Authorization and Action. Each Bank hereby appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement and the other Credit Documents as are
delegated to the Agent by the terms hereof and of the other Credit Documents,
together with such powers as are reasonably incidental thereto. As to any
matters not expressly provided for by this Agreement or any other Credit
Document (including, without limitation, enforcement or collection of the
Notes), the Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions
of the Majority Banks, and such instructions shall be binding upon all Banks
and all holders of Notes; provided, however, that the Agent shall not be
required to take any action which exposes the Agent to personal liability or
which is contrary to this Agreement, any other Credit Document, or applicable
law.

Section VIII.2 Agent's Reliance, Etc. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken
or omitted to be taken (including the Agent's own negligence) by it or them
under or in connection with this Agreement or the other

-62-
<PAGE> 69
Credit Documents, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the Agent:
(a) may treat the payee of any Note as the holder thereof until the Agent
receives written notice of the assignment or transfer thereof signed by such
payee and in form satisfactory to the Agent; (b) may consult with legal counsel
(including counsel for the Borrower), independent public accountants and other
experts selected by it and shall not be liable for any action taken or omitted
to be taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (c) makes no warranty or representation to any Bank and
shall not be responsible to any Bank for any statements, warranties or
representations made in or in connection with this Agreement or the other
Credit Documents; (d) shall not have any duty to ascertain or to inquire as to
the performance or observance of any of the terms, covenants or conditions of
this Agreement or any other Credit Document on the part of the Borrower or its
Subsidiaries or to inspect the property (including the books and records) of
the Borrower or its Subsidiaries; (e) shall not be responsible to any Bank for
the due execution, legality, validity, enforceability, genuineness, sufficiency
or value of this Agreement or any other Credit Document; and (f) shall incur no
liability under or in respect of this Agreement or any other Credit Document by
acting upon any notice, consent, certificate or other instrument or writing
(which may be by telecopier, telegram, cable or telex) believed by it to be
genuine and signed or sent by the proper party or parties.

Section VIII.3 The Agent and Its Affiliates. With respect to its
Revolving Commitment, the Advances made by it and the Notes issued to it, the
Agent shall have the same rights and powers under this Agreement as any other
Bank and may exercise the same as though it were not the Agent. The term
"Bank" or "Banks" shall, unless otherwise expressly indicated, include the
Agent in its individual capacity. The Agent and its Affiliates may accept
deposits from, lend money to, act as trustee under indentures of, and generally
engage in any kind of business with, the Borrower or any of its Subsidiaries,
and any Person who may do business with or own securities of the Borrower or
any such Subsidiary, all as if the Agent were not an agent hereunder and
without any duty to account therefor to the Banks.

Section VIII.4 Bank Credit Decision. Each Bank acknowledges that it
has, independently and without reliance upon the Agent, any Co-Documentation
Agent or any other Bank and based on the financial statements referred to in
Section 4.5 and such other documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Bank also acknowledges that it will, independently and without
reliance upon the Agent, any Co-Documentation Agent or any other Bank and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement.

Section VIII.5 Indemnification. The Banks severally agree to indemnify
the Agent, the Co-Documentation Agents and each Issuing Bank (to the extent not
reimbursed by the Borrower), according to their respective Pro Rata Shares from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by, or asserted against the
Agent, any Co-Documentation Agent or such Issuing Bank in any way relating to
or arising out of this Agreement or any action taken or omitted by the Agent,
any Co-Documentation Agent or such

-63-
<PAGE> 70
Issuing Bank under this Agreement or any other Credit Document (including the
Agent's, such Co-Documentation Agent's or such Issuing Bank's own negligence),
provided that no Bank shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the Agent's, such Co-Documentation
Agent's and such Issuing Bank's gross negligence or willful misconduct.
Without limitation of the foregoing, each Bank agrees to reimburse the Agent
promptly upon demand for its ratable share of any out-of-pocket expenses
(including counsel fees) incurred by the 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
or any other Credit Document, to the extent that the Agent is not reimbursed
for such expenses by the Borrower.

Section VIII.6 Successor Agent and Issuing Banks. The Agent or any
Issuing Bank may resign at any time by giving written notice thereof to the
Banks and the Borrower and may be removed at any time with or without cause by
the Majority Banks upon receipt of written notice from the Majority Banks to
such effect. Upon receipt of notice of any such resignation or removal, the
Majority Banks shall have the right to appoint a successor Agent or Issuing
Bank with, if an Event of Default has not occurred and is not continuing, the
consent of the Borrower, which consent shall not be unreasonably withheld. If
no successor Agent or Issuing Bank shall have been so appointed, and shall have
accepted such appointment, within 30 days after the retiring Agent's or Issuing
Bank's giving of notice of resignation or the Majority Banks' removal of the
retiring Agent or Issuing Bank, then the retiring Agent or Issuing Bank may, on
behalf of the Banks and the Borrower, appoint a successor Agent or Issuing
Bank, which shall be a commercial bank meeting the financial requirements of an
Eligible Assignee and, in the case of an Issuing Bank, a Bank. Upon the
acceptance of any appointment as Agent or Issuing Bank by a successor Agent or
Issuing Bank, such successor Agent or Issuing Bank shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Agent or Issuing Bank, and the retiring Agent or Issuing Bank shall be
discharged from its duties and obligations under this Agreement and the other
Credit Documents, except that the retiring Issuing Bank shall remain an Issuing
Bank with respect to any Letters of Credit issued by such Issuing Bank and
outstanding on the effective date of its resignation or removal and the
provisions affecting such Issuing Bank with respect to such Letters of Credit
shall inure to the benefit of the retiring Issuing Bank until the termination
of all such Letters of Credit. After any retiring Agent's or Issuing Bank's
resignation or removal hereunder as Agent or Issuing Bank, the provisions of
this Article VIII shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was Agent or Issuing Bank under this Agreement and
the other Credit Documents.

Section VIII.7 Co-Documentation Agents. The Co-Documentation Agents
shall have no duties, obligations or liabilities in their capacity as
Co-Documentation Agents.

Section IX.6 Bank Assignments and Participations.

(1) Assignments. Any Bank may assign to one or more banks or
other entities all or any portion of its rights and obligations under this
Agreement (including, without limitation, all or a portion of its Revolving
Commitment, the Advances owing to it, the Notes held by it, and the
participation interest in the Letter of Credit Obligations held by it);
provided, however, that (i) each such assignment shall be of a constant, and
not a varying, percentage of all of such Bank's rights and obligations under
this Agreement and shall involve a ratable assignment of such Bank's Revolving
Commitment and such Bank's Revolving Advances, (ii) the amount of the resulting
Revolving Commitment and Revolving Advances of the assigning Bank (unless it is
assigning all its Revolving Commitment) and the assignee Bank pursuant to each
such assignment (determined as of the date of the Assignment and Acceptance
with respect to such assignment) shall in no event be less than $10,000,000 and
shall be an integral multiple of $1,000,000, (iii) each such assignment shall
be to an Eligible Assignee, (iv) the parties to each such assignment shall

-66-
<PAGE> 73
assignment, and (v) each Eligible Assignee (other than the Eligible Assignee of
the Agent or an Eligible Assignee which is an Affiliate of the assigning Bank)
shall pay to the Agent a $3,000 administrative fee. Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment and Acceptance, which effective date shall be at least three
Business Days after the execution thereof, (A) the assignee thereunder shall be
a party hereto for all purposes and, to the extent that rights and obligations
hereunder have been assigned to it pursuant to such Assignment and Acceptance,
have the rights and obligations of a Bank hereunder and (B) such Bank
thereunder shall, to the extent that rights and obligations hereunder have been
assigned by it pursuant to such Assignment and Acceptance, relinquish its
rights and be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all or the remaining portion of
such Bank's rights and obligations under this Agreement, such Bank shall cease
to be a party hereto). Notwithstanding anything herein to the contrary, any
Bank may assign, as collateral or otherwise, any of its rights under the Credit
Documents to any Federal Reserve Bank.

(2) Term of Assignments. By executing and delivering an
Assignment and Acceptance, the Bank thereunder and the assignee thereunder
confirm to and agree with each other and the other parties hereto as follows:
(i) other than as provided in such Assignment and Acceptance, such Bank makes
no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency of value of this Agreement or any other instrument or document
furnished pursuant hereto; (ii) such Bank makes no representation or warranty
and assumes no responsibility with respect to the financial condition of the
Borrower or the Guarantors or the performance or observance by the Borrower or
the Guarantors of any of their obligations under this Agreement or any other
instrument or document furnished pursuant hereto; (iii) such assignee confirms

financial statements referred to in Section 4.5 and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Agent, such Bank or any other Bank
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under this Agreement; (v) such assignee appoints and authorizes the Agent to
take such action as agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Agent by the terms hereof, together with such
powers as are reasonably incidental thereto; and (vi) such assignee agrees that
it will perform in accordance with their terms all of the obligations which by
the terms of this Agreement are required to be performed by it as a Bank.

(3) The Register. The Agent shall maintain at its address
referred to in Section 9.2 a copy of each Assignment and Acceptance delivered
to and accepted by it and a register for the recordation of the names and
addresses of the Banks and the Revolving Commitments of, and principal amount
of the Advances owing to, each Bank from time to time (the "Register"). The
entries in the Register shall be conclusive and binding for all purposes,
absent manifest error, and the Borrower, the Agent, the Issuing Banks, and the
Banks may treat each Person whose name is recorded in the Register as a Bank
hereunder for all purposes of this

-67-
<PAGE> 74
Agreement. The Register shall be available for inspection by the Borrower or
any Bank at any reasonable time and from time to time upon reasonable prior
notice.

(4) Procedures. Upon its receipt of an Assignment and
Acceptance executed by a Bank and an Eligible Assignee, together with the
Revolving Note or, in the case of an assignment to another Bank, Revolving
Notes subject to such assignment, the Agent shall, if such Assignment and
Acceptance has been completed and is in substantially the form of the attached
Exhibit G, (i) accept such Assignment and Acceptance, (ii) record the
information contained therein in the Register, and (iii) give prompt notice
thereof to the Borrower. Within five Business Days after its receipt of such
notice, the Borrower, at its own expense, shall execute and deliver to the
Agent in exchange for such Note or Notes, a new Revolving Note payable to the
order of such Eligible Assignee in amount equal to the Revolving Commitment
assumed by it pursuant to such Assignment and Acceptance, and if the assigning
Bank has retained any Revolving Commitment hereunder, a new Revolving Note
payable to the order of such Bank in an amount equal to, respectively, the
Revolving Commitment retained by it hereunder. Such new Notes shall be dated
the effective date of such Assignment and Acceptance and shall otherwise be in
substantially the form of the attached Exhibit A.

(5) Participations. Each Bank may sell participations to one
or more banks or other entities in or to all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Revolving Commitment, the Advances owing to it, its
participation interest in the Letter of Credit Obligations, and the Revolving
Note held by it); provided, however, that (i) such Bank's obligations under
this Agreement (including, without limitation, its Revolving Commitment to the
Borrower hereunder) shall remain unchanged, (ii) such Bank shall remain solely
responsible to the other parties hereto for the performance of such
obligations, (iii) such Bank shall remain the holder of any such Note for all
purposes of this Agreement, (iv) the Borrower, the Agent, and the Issuing Banks
and the other Banks shall continue to deal solely and directly with such Bank
in connection with such Bank's rights and obligations under this Agreement, (v)
such Bank shall not require the participant's consent to any matter under this
Agreement, except for change in the principal amount of any Note in which the
participant has an interest, reductions in fees or interest, or extending the
Maturity Date, and (vi) such Bank shall give prompt prior notice to the
Borrower of each such participation to be sold by such Bank. The Borrower
hereby agrees that participants shall have the same rights under Sections 2.8,
2.9, 2.11(c), and 9.7 hereof as the Bank to the extent of their respective
participations. Notwithstanding the foregoing, upon the receipt of notice by
the Borrower of the sale of a participation by any Bank to one or more banks or
other entities (other than an Affiliate of such Bank) in or to all or a portion
of its rights and obligations under this Agreement (each such bank or other
entity, a "Proposed Participant"), the Borrower shall have the right, but not
the obligation, to select additional banks to replace such Proposed Participant
on the same terms and conditions as the Proposed Participant upon prompt
written notice from the Borrower to the Agent and the Bank selling such
participation. The Borrower shall have ten days from the date of its receipt of
notice of the proposed sale of such participation to the Proposed Participant
to select replacement banks to replace such Proposed Participant. If the
Borrower does not select any replacement banks or does not elect to select any
replacement banks the applicable Bank may sell such participation to the
Proposed Participant.

-68-
<PAGE> 75
(6) Confidentiality. Each Bank may furnish any information
concerning the Borrower and its Subsidiaries in the possession of such Bank
from time to time to assignees and participants (including prospective
assignees and participants); provided that, prior to any such disclosure, the
assignee or participant or proposed assignee or participant shall agree in
writing to preserve the confidentiality of any confidential information
relating to the Borrower and its Subsidiaries received by it from such Bank.
Such Bank shall promptly deliver a signed copy of any such confidentiality
agreement to the Borrower.

Section IX.7 Indemnification. The Borrower shall indemnify the Agent,
the Co-Documentation Agents, the Banks (including any lender which was a Bank
hereunder prior to any full assignment of its Revolving Commitment), the
Issuing Banks, and each affiliate thereof and their respective directors,
officers, employees and agents from, and discharge, release, and hold each of
them harmless against, any and all losses, liabilities, claims or damages to
which any of them may become subject, insofar as such losses, liabilities,
claims or damages arise out of or result from (i) any actual or proposed use by
the Borrower or any Affiliate of the Borrower of the proceeds of any Advance,
(ii) any breach by the Borrower or any Guarantor of any provision of this
Agreement or any other Credit Document, (iii) any investigation, litigation or
other proceeding (including any threatened investigation or proceeding)
relating to the foregoing, or (iv) any Environmental Claim or requirement of
Environmental Laws concerning or relating to the present or previously-owned or
operated properties, or the operations or business, of the Borrower or any of
its Subsidiaries, and the Borrower shall reimburse the Agent, each
Co-Documentation Agent, each Issuing Bank, and each Bank, and each affiliate
thereof and their respective directors, officers, employees and agents, upon
demand for any reasonable out-of-pocket expenses (including legal fees)
incurred in connection with any such investigation, litigation or other
proceeding; and EXPRESSLY INCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS,
DAMAGES, OR EXPENSE INCURRED BY REASON OF THE PERSON BEING INDEMNIFIED'S OWN
NEGLIGENCE, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES OR
EXPENSES INCURRED BY REASON OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF
THE PERSON TO BE INDEMNIFIED.

Section IX.8 Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

Section IX.9 Survival of Representations, etc. All representations
and warranties contained in this Agreement or made in writing by or on behalf
of the Borrower in connection herewith shall survive the execution and delivery
of this Agreement and the Credit Documents, the making of the Advances and any
investigation made by or on behalf of the Banks, none of which investigations
shall diminish any Bank's right to rely on such representations and warranties.
All obligations of the Borrower provided for in Sections 2.8, 2.9, 2.11(c), and

Section IX.10 Severability. In case one or more provisions of this
Agreement or the other Credit Documents shall be invalid, illegal or
unenforceable in any respect under any applicable law, the validity, legality
and enforceability of the remaining provisions contained herein or therein
shall not be affected or impaired thereby.

Section IX.11 Business Loans. The Borrower warrants and represents
that the Advances evidenced by the Notes are and shall be for business,
commercial, investment or other similar purposes and not primarily for
personal, family, household or agricultural use, as such terms are used in
Chapter One ("Chapter One") of the Texas Credit Code. At all such times, if
any, as Chapter One shall establish a Maximum Rate, the Maximum Rate shall be
the "indicated rate ceiling" (as such term is defined in Chapter One) from time
to time in effect.

Section IX.12 Usury Not Intended. It is the intent of the Borrower and
each Bank in the execution and performance of this Agreement and the other
Credit Documents to contract in strict compliance with applicable usury laws,
including conflicts of law concepts, governing the Advances of each Bank
including such applicable laws of the State of Texas and the United States of
America from time to time in effect. In furtherance thereof, the Banks and the
Borrower stipulate and agree that none of the terms and provisions contained in
this Agreement or the other Credit Documents shall ever be construed to create
a contract to pay, as consideration for the use, forbearance or detention of
money, interest at a rate in excess of the Maximum Rate and that for purposes
hereof "interest" shall include the aggregate of all charges which constitute
interest under such laws that are contracted for, charged or received under
this Agreement; and in the event that, notwithstanding the foregoing, under any
circumstances the aggregate amounts taken, reserved, charged, received or paid
on the Advances, include amounts which by applicable law are deemed interest
which would exceed the Maximum Rate, then such excess shall be deemed to be a
mistake and each Bank receiving same shall credit the same on the principal of
its Notes (or if such Notes shall have been paid in full, refund said excess to
the Borrower). In the event that the maturity of the Notes is accelerated by
reason of any election of the holder thereof resulting from any Event of
Default under this Agreement or otherwise, or in the event of any required or
permitted prepayment, then such consideration that constitutes interest may
never include more than the Maximum Rate and excess interest, if any, provided
for in this Agreement or otherwise shall be canceled automatically as of the
date of such acceleration or prepayment and, if theretofore paid, shall be
credited on the applicable Notes (or, if the applicable Notes shall have been
paid in full, refunded to the Borrower). The provisions of this Section shall
control over all other provisions of this Agreement or the other Credit
Documents which may be in apparent conflict herewith.

Section IX.13 Governing Law. This Agreement, the Notes and the other
Credit Documents shall be governed by, and construed and enforced in accordance
with, the laws of the State of Texas.

Section IX.14 Consent to Jurisdiction. The Borrower hereby irrevocably
submits to the jurisdiction of any Texas state or federal court sitting in
Dallas, Texas in any action or proceeding arising out of or relating to this
Agreement, the Notes and the other Credit Documents, and the Borrower hereby
irrevocably agrees that all claims in respect of such action or proceeding may
be heard and determined in such court. The Borrower hereby irrevocably

waives, to the fullest extent it may effectively do so, any right it may have
to the defense of an inconvenient forum to the maintenance of such action or
proceeding. The Borrower hereby agrees that service of copies of the summons
and complaint and any other process which may be served in any such action or
proceeding may be made by mailing or delivering a copy of such process to the
Borrower at its address specified in Section 9.2. The Borrower agrees that a
final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Section shall affect the rights of any Bank,
the Agent, or any Co-Documentation Agent to serve legal process in any other
manner permitted by the law or affect the right of any Bank, the Agent or any
Co-Documentation Agent to bring any action or proceeding against the Borrower
or its Property in the courts of any other jurisdiction.

Section IX.15 Banks Not in Control. None of the covenants or other
provisions contained in the Credit Documents shall or shall be deemed to, give
the Banks the rights or power to exercise control over the affairs and/or
management of the Borrower, any of its Subsidiaries or any Guarantor, the power
of the Banks being limited to the right to exercise the remedies provided in
the Credit Documents; provided, however, that if any Bank becomes the owner of
any stock, or other equity interest in, any Person whether through foreclosure
or otherwise, such Bank shall be entitled (subject to requirements of law) to
exercise such legal rights as it may have by being owner of such stock, or
other equity interest in, such Person.

Section IX.16 Headings Descriptive. The headings of the several
Sections and paragraphs of the Agreement are inserted for convenience only and
shall not in any way affect the meaning or construction of any provision of
this Agreement.

SECTION IX.17 WAIVERS OF JURY TRIAL. THE BORROWER, THE AGENT AND THE
BANKS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL
PROCEEDING RELATING TO THIS AGREEMENT OR THE NOTES OR ANY OTHER CREDIT DOCUMENT
OR TO ANY COUNTERCLAIM THEREIN.

SECTION IX.18 ENTIRE AGREEMENT. PURSUANT TO SECTION 26.02 OF THE TEXAS
BUSINESS AND COMMERCE CODE, A LOAN AGREEMENT IN WHICH THE AMOUNT INVOLVED IN
THE LOAN AGREEMENT EXCEEDS $50,000 IN VALUE IS NOT ENFORCEABLE UNLESS THE LOAN
AGREEMENT IS IN WRITING AND SIGNED BY THE PARTY TO BE BOUND OR THAT PARTY'S
AUTHORIZED REPRESENTATIVE.

THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO AN AGREEMENT SUBJECT TO THE
PRECEDING PARAGRAPH SHALL BE DETERMINED SOLELY FROM THE WRITTEN LOAN AGREEMENT,
AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY AND MERGED
INTO THE LOAN AGREEMENT. THIS WRITTEN AGREEMENT AND THE CREDIT DOCUMENTS, AS
DEFINED IN THIS AGREEMENT, REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND
MAY NOT BE CONTRADICTED BY
