                  Notes to Consolidated Financial Statements
                                  (Unaudited)



(1)  Basis of Presentation

     Although the interim consolidated financial statements of CellStar
     Corporation and subsidiaries (the "Company") are unaudited, it is the
     opinion of the Company's management that all adjustments (consisting of
     only normal recurring adjustments) necessary for a fair statement of the
     results have been reflected therein.  Operating revenues and net income for
     any interim period are not necessarily indicative of results that may be
     expected for the entire year.

     These statements should be read in conjunction with the consolidated
     financial statements and related notes included in the Company's Annual
     Report on Form 10-K for the year ended November 30, 1998.

     Certain prior period financial statement amounts have been reclassified to
     conform to the current year presentation.

(2)  Investment in Topp Telecom, Inc.

     In February 1999, the Company sold part of its equity investment in Topp
     Telecom, Inc. ("Topp") to a wholly-owned subsidiary of Telefonos de Mexico
     S.A. de C.V. ("TelMex").   At the closing, the Company also sold a portion
     of its debt investment to certain other shareholders of Topp.  As a result
     of these transactions, the Company received cash in the amount of $7.0
     million, retained a $22.5 million note receivable and a 19.5% equity
     ownership interest in Topp and recorded a pre-tax gain of $5.8 million.
     The gain is recorded in equity in income of affiliated companies in the
     consolidated statements of operations for the nine months ended August 31,
     1999.

     In September 1999, the Company sold its remaining debt and equity
     investment in Topp for $26.5 million in cash to a wholly owned subsidiary
     of TelMex.  The Company will recognize an after-tax gain of approximately
     $16 million in the fourth quarter ending November 30, 1999. The Company
     expects to continue serving as Topp's primary distributor of prepaid
     wireless products.

(3)  Net Income Per Share

     Basic net income per common share is based on the weighted average number
     of common shares outstanding for the relevant period.  Diluted net income
     per common share is based on the weighted average number of common shares
     outstanding plus the dilutive effect of potentially issuable common shares
     pursuant to a warrant, stock options and convertible notes.

                                                                               7

(4)  Segment and Related Information

     Effective November 30, 1998, the Company adopted Statement of Financial
     Accounting Standards No. 131, "Disclosures About Segments of an Enterprise
     and Related Information."  Segment information for the three and nine
     months ended August 31, 1998 has been restated to conform to the new
     presentation.

     The Company operates predominantly within one industry, wholesale and
     retail sales of wireless telecommunications products.  The Company's
     management evaluates operations primarily on income before interest and
     income taxes in the following reportable geographical regions: North
     America, primarily the United States, Asia-Pacific, Latin America, which
     includes Mexico and the Company's Miami, Florida operations ("Miami"), and
     Europe.  Revenues and operating results of Miami are included in Latin
     America since Miami's activities are primarily for export customers.  The
     Corporate group includes headquarter operations, income and expenses not
     allocated to reportable segments, and interest expense on the Company's
     Multicurrency Revolving Credit Facility and long-term debt.  Intersegment
     sales and transfers are not significant.

                                                                               9

(5)  Foreign Currency Non-deliverable Forward Contracts

     During the second quarter of 1999, the remaining Brazilian real non-
     deliverable forward ("NDF") contracts, which were outstanding at February
     28, 1999, were settled.  These NDF contracts and other NDF contracts of
     similar nature were used to manage the Company's foreign currency exposure
     to the Brazilian real with respect to certain credit sales made to E.A.
     Electronicos e Componentes Ltda. ("E.A."), a Brazilian importer.  Foreign
     currency rate fluctuations caused bad debt expense of $26.4 million related
     to the payments remitted by E.A.  This expense was recorded in selling,
     general and administrative expenses for the nine months ended August 31,
     1999, but this expense was completely offset by gains realized on NDF
     contract settlements, which gains also were recorded in selling, general
     and administrative expenses.

(6)  Restructuring Charge

     As part of the Company's strategy to streamline its organizational
     structure, beginning in the second quarter of 1999 the Company reorganized
     and consolidated the management of the Company's Latin American and North
     American Regions and centralized the management in the Company's Asia-
     Pacific Region.  As a result, the consolidated statements of operations for
     the nine months ended August 31, 1999 include a charge of $3.0 million
     related to the reorganization.  Of the total costs, $0.4 million consisted
     of non-cash outlays and the remaining $2.6 million consisted of cash
     outlays, of which $2.5 million had been paid through August 31, 1999.  The
     components of the restructuring charge were as follows (in thousands):

     Employee termination costs                  $2,373
     Write-down of assets                           406
     Other                                          202
                                                --------
                                                 $2,981
                                                ========

     The Company expects to incur an additional $0.5 million related to this
     reorganization in the fourth quarter of 1999.

(7)  Accounting Pronouncement Not Yet Adopted

     In June 1998, the Financial Accounting Standards Board issued Statement No.
     133, "Accounting for Derivative Instruments and Hedging Activities"
     ("Statement 133"), which was amended by Statement 137 issued in July 1999.
     Statement 137 delayed the effective date of Statement 133.  Statement 133
     is now effective for all interim and annual periods of the Company
     commencing December 1, 2000. Given the Company's current and anticipated
     derivative activities, management does not believe the adoption of
     Statement 133 will have a material effect on the Company's consolidated
     financial position and results of operations.

(8)  Contingency

     For a description of pending legal proceedings, see Part II - Other
     Information, Item 1 - Legal Proceedings.

(9)  Subsequent Event

     In September 1999, the Company sold its remaining debt and equity
     investment in Topp for $26.5 million in cash to a wholly owned subsidiary
     of TelMex.  The Company will recognize an after-tax gain of approximately
     $16 million in the fourth quarter ending November 30, 1999. The Company
     expects to continue serving as Topp's primary distributor of prepaid
     wireless products.

                                                                              12

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

Overview

         The Company reported net income of $15.0 million, or $0.25 per diluted
share, for the third quarter of 1999 compared with net income of $2.4 million or
$0.04 per diluted share, for the same quarter last year. The third quarter of
1998 was impacted by a pre-tax charge of $9.1 million on the Company's expanded
debt and equity investment in Topp. Excluding the non-recurring charge, net
income was $8.2 million, or $0.14 per diluted share.

         The Company derives substantially all revenues from net product sales,
which includes sales of handsets and other wireless communications products.
Value added service revenues include fulfillment service fees, handling fees and
assembly revenues. Activation income includes commissions paid by a wireless
carrier when a customer initially subscribes for wireless service through the
Company. Residual income includes payments received from carriers based on the
wireless handset usage by a customer activated by the Company.

Special Cautionary Notice Regarding Forward-Looking Statements

         This Quarterly Report on Form 10-Q contains forward-looking statements
relating to such matters as anticipated financial performance and business
prospects.  When used in this Quarterly Report, the words "may," "intends",
"expects," "anticipates," "will" and similar expressions are intended to be
among the statements that identify forward-looking statements.  From time to
time, the Company may also publish forward-looking statements.  The Private
Securities Litigation Reform Act of 1995 provides a safe harbor for forward-
looking statements.  In order to comply with the terms of the safe harbor, the

political instability, changes in foreign laws, regulations and tariffs, new
technologies, competition, customer and vendor relationships, seasonality,
inventory obsolescence and availability, "gray market" resales, inflation, and
Year 2000 issues and costs could cause the Company's actual results and
experience to differ materially from anticipated results or other expectations
expressed in the Company's forward-looking statements.

                                                                              13

Three Months Ended August 31, 1999 Compared to Three Months Ended August 31,
1998

  Revenues.  The Company's revenues increased $58.4 million, or 11.6%, from
$501.8 million to $560.2 million.

  Revenues in the Asia-Pacific Region increased $51.8 million, or 34.0%, from
$152.3 million to $204.1 million.  The Company's operations in the People's
Republic of China, including Hong Kong ("PRC"), provided $138.8 million in
revenue, an increase of $13.6 million, or 10.9%, from $125.2 million.  This
increase was due to continued strong demand in the PRC, coupled with a broadened
source of product manufactured in-country and the impact of the PRC's tighter
customs controls on imported products beginning in August 1998.  The Company's
operations in Taiwan provided $51.1 million of revenue, an increase of $34.5
million, from $16.6 million.  Demand continued to increase in Taiwan due to the
availability of new high-end digital handsets.

  The Latin American Region provided $154.6 million of revenues, compared to
$157.2 million, or a 1.7% decrease.  Revenues for Mexico, Brazil, Chile,
Venezuela and Colombia increased $24.6 million, $11.0 million, $4.4 million,
$4.3 million and $3.5 million, respectively.  Mexico revenues benefited from
carrier promotions as well as the introduction of the calling-party-pays billing
process.  The increase in Brazil was due to revenue growth in the Company's
majority-owned joint venture, which benefited from the privatization of the
telecommunication industry and the entry of additional carriers into the
wireless market during the latter half of 1998.  The increase in Chile and
Venezuela was due to increased handset sales to carriers.  In connection with
the sale of the prepaid wireless business in Venezuela in March 1999, the
Company was awarded an exclusive two-year contract to supply services for
prepaid phone kits.  Revenue in Colombia increased as a result of new contracts
with two of the country's primary carriers.  Revenues in the remainder of the
region decreased $50.4 million, primarily in Miami.  The decrease in Miami was
due to the increased product availability from in-country suppliers, thereby
reducing export sales from Miami.

     North American Region revenues were $93.5 million, a decrease of $22.7
million, or 19.5%, when compared to $116.2 million. The decrease was almost
entirely a result of lower product sales to Pacific Bell Mobile Services
("PBMS") in the third quarter of 1999 as compared to the third quarter of 1998
due to PBMS increasingly coordinating its handset distribution directly with
manufacturers.   The decrease was also due to continued decreases in the retail
business due to the sale of almost all of the Company's retail stores in early
1999.  The overall decrease in revenues was partially offset by an increase in
the wholesale business which increased 28% relative to last year.

  The Company's European Region recorded revenues of $108.0 million, an increase
of $32.0 million, or 42.1%, from $76.0 million.  This increase reflected
continued growth from the Company's U.K. operation, arising primarily from sales
in international markets, as well as increased revenues from the operation in
Sweden.

     Gross Profit.  Gross profit increased $6.7 million, or 16.3%, from $41.0
million to $47.7 million, while gross profit as a percentage of revenues
increased from 8.2% to 8.5%.  The increase in gross profit was principally due
to increases in both the Asia-Pacific and European Regions.  The increase in the
Asia-Pacific Region was due to the increased demand in Taiwan as a result of the
availability of new high-end digital handsets and the continued strong demand in
the PRC.  The increase in the European Region was due to the continued growth of
the Company's operations in the U.K. and Sweden.  The increase in gross profit
as a percentage of revenues was due primarily to an increase in the North
American Region as the North American operations continue to focus on cost
control and providing distribution and value-added services to carriers.

                                                                              15
<PAGE>

     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses decreased $2.8 million, or 10.2%, from $27.5 million to
$24.7 million as the Company began to see the effects of the second quarter
consolidation of its North and Latin American Regions operations.  Overall
selling, general and administrative expenses as a percentage of revenues
decreased to 4.4% from 5.5%.

     Equity in Income (Loss) of Affiliated Companies.  Equity in the loss of
affiliated companies decreased $8.6 million, from a loss of $8.8 million in 1998
to a loss of $0.2 million in 1999, primarily as a result of the Company's
recognition of $9.1 million of losses on its debt and equity investment in Topp
in 1998.

     Interest Expense.  Interest expense increased to $4.4 million from $3.6
million primarily as a result of an increase in debt related to the Company's
operations in Brazil as well as an increase in borrowings under the Company's
Multicurrency Revolving Credit Facility.

     Income Taxes.  Income tax expense increased $6.4 million primarily as a
result of a $19.0 million increase in income before income taxes, and the
Company's effective tax rate increased to 22.0%.  The higher effective tax rate
was attributable to an increase in the percentage of the Company's total income
before income taxes from Latin America and Europe where the statutory tax rates
are generally comparable to the statutory rates in the United States and higher
than the statutory rates in Asia.  In addition, the utilization of net operating
loss carryforwards to offset 1998 income in certain jurisdictions contributed to
the lower effective tax rate for 1998.

                                                                              16

Nine Months Ended August 31, 1999 Compared to Nine Months Ended August 31, 1998

     Revenues.  The Company's revenues increased $291.7 million, or 21.5%, from
$1,354.2 million to $1,645.9 million.

     Revenues in the Asia-Pacific Region increased $200.6 million, or 60.6%,
from $330.8 million to $531.4 million.  The Company's operations in the PRC
provided $361.6 million in revenue, an increase of $91.5 million, or 33.9%, from
$270.1 million. This increase continued to be driven by the strong demand in the
PRC, coupled with a broadened source of product manufactured in-country and the
impact of the PRC's tighter customs controls on imported products, which began
in the third quarter of 1998.  The Company's operations in Taiwan provided
$130.9 million of revenue, an increase of $99.8 million, or 320.9%, from $31.1
million.  Demand in Taiwan increased due to the entry of several new wireless
carriers into the market during 1998 as well as the introduction of new high-end
digital handsets.

     The Latin American Region provided $511.7 million of revenues, compared to
$515.8 million, or a $4.1 million decrease.  Revenues in Brazil, Mexico,
Venezuela, and Peru increased $136.8 million, $32.5 million, $28.4 million and
$8.2 million, respectively.  The increase in Brazil was due to revenue growth in
the Company's majority-owned joint venture, which benefited from the
privatization of the telecommunication industry and the entry of additional
carriers into the wireless market during the latter half of 1998.  The increase
in Mexico was largely due to carrier promotions coupled with the introduction of
the calling-party-pays billing process.  The increase in Venezuela was a result
of additional handset sales to carriers.  The Company was also awarded an
exclusive two-year contract to supply services for prepaid phone kits in
connection with the sale of its prepaid wireless business in Venezuela in March
1999.  The Company began its operation in Peru through the acquisition of a
prepaid wireless business in the second quarter of 1998.  Revenues in the
remainder of the region decreased $210.0 million, primarily in Miami.  The
decrease in Miami was due to increased product availability from in-country
suppliers, thereby reducing export sales from Miami.

     North American Region revenues were $296.5 million, a decrease of $41.3
million, or 12.2%, when compared to $337.8 million.  The decrease was primarily
a result of lower product sales to PBMS in 1999 as compared to 1998 as PBMS is
increasingly coordinating its handset distribution directly with manufacturers.
The decrease was also attributable to a continued decrease in the retail
business due to the sale of almost all of the Company's retail stores in early
1999. The overall decrease in revenues was partially offset by an increase in
the U.S. wholesale business.

     The Company's European Region recorded revenues of $306.3 million, an
increase of $136.6 million, or 80.5%, from $169.7 million.  This increase
reflected continued growth from the Company's U.K. operation, arising primarily
from sales in international markets, as well as increased revenues from the
operation in Sweden, which was acquired in the first quarter of 1998.

     Gross Profit.  Gross profit increased $13.1 million, or 10.3%, from $127.3
million to $140.4 million, while gross profit as a percentage of revenues
decreased from 9.4% to 8.5%.   The increase in gross profit was principally due
to increases in both the European and Asia-Pacific Regions.  The increase in the
European Region was due to the continued growth of the U.K. operation and the
increased revenues from the Company's operation in Sweden. The overall increase
in the Asia-Pacific Region was primarily due to the increase in Taiwan, which
was offset partially by a decrease in the PRC.  The decrease in gross profit as
a percentage of revenues was due primarily to a $12 million provision for
inventory obsolescence recorded in the second quarter of 1999, as the Company
aggressively managed its inventory, and was also due to decreases in market
prices of certain handsets at the end of the second quarter, primarily in Asia.
The decrease in gross profit as a percentage of revenues can also be attributed

                                                                              17
<PAGE>

to an increase in revenues from the European Region, which has lower margins
than the Company's other regions.

     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased $4.7 million, or 6.4% from $74.0 million to
$78.7 million.  This increase was primarily due to a provision for doubtful
accounts receivable of $7.3 million, up from $4.6 million for the same period
last year. This increase was due primarily to the Latin American Region and an
increase in the costs associated with the Company's growth in revenues.  Overall
selling, general and administrative expenses as a percentage of revenues
decreased to 4.8% from 5.5%.

     Restructuring Charge.  The Company's results of operations include a pre-
tax restructuring charge of $3.0 million associated with the reorganization and
consolidation of the management for the Company's Latin American and North
American Regions as well as the centralization of management in the Asia-Pacific
Region.  The Company expects to incur an additional $0.5 million related to this
reorganization in the fourth quarter of 1999.

     Equity in Income (Loss) of Affiliated Companies.  Equity in income (loss)
of affiliated companies increased $14.3 million to income of $5.9 million, as
compared to a loss of $8.4 million in 1998.  In the third quarter of 1998, the
Company recognized $9.1 million in losses in connection with its expanded debt
and equity investment in Topp.  In February 1999, the Company sold part of its
equity investment in Topp to a wholly owned subsidiary of TelMex.  At the
closing, the Company also sold a portion of its debt investment to certain other
shareholders of Topp.  As a result of these transactions, the Company received
cash in the amount of $7.0 million, retained a $22.5 million note receivable and
a 19.5% equity ownership interest in Topp, and recorded a pre-tax gain of $5.8
million.

     Gain on Sale of Assets.  The Company recorded a pre-tax gain of $8.2
million in 1999 associated with the sale of its prepaid operations in Venezuela
and its retail stores in the Dallas-Fort Worth and Kansas City areas.

     Interest Expense.  Interest expense increased to $14.5 million from $8.7
million, primarily as a result of an increase in debt related to the Company's
operations in Brazil, as well as an increase in borrowings under the Company's
Multicurrency Revolving Credit Facility.

     Other, Net.  Other, net decreased $1.7 million, from income of $0.3 million
to expense of $1.4 million.  This decrease was primarily due to a $2.6 million
foreign currency transaction loss realized from the conversion of U.S. dollar
denominated debt in Brazil into a Brazilian real denominated credit facility.

     Income Taxes.  Income tax expense increased $9.3 million primarily as a
result of a $20.6 million increase in income before income taxes and an increase
in the Company's effective tax rate to 22.0% from 9.0%.  The higher effective
tax rate was attributable to higher income before income taxes, primarily in the
Latin American and European Regions, where the statutory tax rates are generally
comparable to the statutory rate in the United States, and higher than the
statutory rates in the Company's other regions.  The utilization of net
operating loss carryforwards to offset 1998 income in certain jurisdictions
contributed to the lower effective tax rate for 1998.

                                                                              18

International Operations

     The Company's international operations are subject to political and
economic risks, including but not limited to political instability, currency
devaluations and controls, increased credit risks and changing tax and trade
regulations.  The Company experienced no material net foreign currency
translation gains or losses during the third quarter of 1999.

     During the second half of 1998, the Company's sales from Miami to customers
exporting into South American countries began to decline as a result of
increased in-country product availability in South America, primarily Brazil.
The Company expects to focus its efforts on servicing large, financially sound
carrier partners from the Company's Latin American subsidiaries.

     Based upon changes in the market in Poland, the Company is currently re-
evaluating the future operating prospects of the Company's Poland subsidiary.
The Company has net goodwill of $4.6 million relating to the Poland subsidiary.
The Company is currently assessing the net realizable value of goodwill by
determining the estimated future cash flows.  In the event that the goodwill is
found to be carried at an amount which is in excess of estimated future
operating cash flows, then the goodwill will be adjusted for impairment to an
amount commensurate with the underlying cash flow analysis.

                                                                              19
<PAGE>

Liquidity and Capital Resources

     During the nine months ended August 31, 1999, the Company relied primarily
on cash available at November 30, 1998, cash generated from operations and
borrowings under its Multicurrency Revolving Credit Facility (the "Facility") to
fund working capital, capital expenditures and expansions. On April 8, 1999, the
amount of the Facility was reduced from $135.0 million to $115.0 million due to
the release of a syndication member bank. On August 2, 1999, the Company
restructured its Facility to add additional flexibility for foreign working
capital funding and capitalization. Also under this restructuring, the Company
received expanded borrowing capability on its domestic assets.

     In September 1999, the Company sold the balance of its remaining debt and
equity investment in Topp to a wholly owned subsidiary of TelMex.  As a result
of this transaction, the Company received cash in the amount of $26.5 million.
This cash, along with cash generated from operations, allowed the Company to
eliminate its borrowings on its Facility as of October 7, 1999.  The Company had
available $53.3 million of borrowing capacity under the Facility and cash of
$55.3 million at October 7, 1999.

     Compared to November 30, 1998, accounts receivable, inventories and
accounts payable at August 31, 1999 decreased $64.9 million, $119.1 million and
$157.2 million, respectively.  These decreases are primarily a result of the
Company's continuing focus to aggressively manage its balance sheet and cash
cycle.

     As of August 31, 1999 and September 30, 1999, the Company's Brazilian
operations had borrowed $11.0 million and $11.3 million, respectively, using
credit facilities denominated in Brazilian reals with Brazilian banks. In
conjunction therewith, the Company has $9.2 million of letters of credit against
its Facility to guarantee the repayment of the principal plus interest and all
other contractual obligations of its Brazilian operations to one of the
Brazilian banks.

     The Company anticipates that it will have sufficient cash available to meet
its capital and operating requirements. Capital is expected to be provided by
available cash on hand, cash generated from operations, amounts available from
the Facility and various other funded debt sources.  The Company believes that
it will have the ability to expand its borrowing sources to accommodate expected
capital needs in the future.

Year 2000

     Since June 1997, the Company has been implementing a plan to assess and
resolve Year 2000 issues that may affect it.  The Company believes that the Year
2000 issues it must address include ensuring (i) that its information technology
systems (hardware and software) enable it to manage and operate its business and
(ii) that its non-information technology systems (including heating and air
conditioning systems and warehouse equipment) will continue to operate and (iii)
that assessments and planning has been conducted related to managing
interruption to its supply and demand chain.

     The phases and timetable for the Company's plans are as follows:

     Phase I.   Create awareness of and identify Year 2000 issues (June 1997 -
                July 1997)

     Phase II.  Assess and renovate existing systems (July 1997 - July 1999)

     Phase III. Validate and test systems (July 1998 - July 1999)

                                                                              20
<PAGE>

     Phase IV.  Complete Year 2000 compliance (March 1999 - November 1999)

     The Company has substantially completed the planned tasks. The Company has
extended Phase IV to allow for refinement of the contingency planning and the
local validation of corporate testing results at the in-country locations.  A
project structure is defined, progress and issues are tracked, and management is
provided updates.  The Company does not believe it has material, potential
liability to third parties if its systems are not Year 2000 compliant.

     The Company has made substantial progress in assessing Year 2000 issues
that affect third parties with which it has material relationships.  The Company
has substantially completed the process of contacting manufacturers of products
that the Company sells and has reviewed each response.  The responses and
continuing informal contact with the primary manufacturers and suppliers of
products indicate that the suppliers believe they are addressing and resolving
their Year 2000 issues and expect minimal operational impact. The Company has
reviewed all electronic exchanges of data between customers and suppliers for
Year 2000 compliance.  The Company substantially completed all remediation
efforts related to exchange of data.  The Company has also completed testing and
certification of its mission critical applications and systems.  Individual
country sites are in the process of confirming corporate results.  Even though
the Company does not believe that its customers' Year 2000 compliance issues
will have a significant impact on the Company, the Company has continued to
review, contact, and assess the progress of its major customers in each region
as to risk and exposure related to Year 2000 issues.   The Company also
recognizes that demand for its products is affected by the ability of carriers
and network operators to continue operation without significant interruption.
These risks are being considered by the Company in developing pertinent business
interruption and contingency plans.  Although the Company has taken actions with
regard to its systems and environment, there is no guarantee that the company
will not be impacted by factors outside of its control such as utility and
country specific infrastructure failures.

     The Company's costs of compliance with Year 2000 requirements are
immaterial because it was in the process of upgrading or establishing systems to
keep pace with its growth.

     The Company believes that it and its material suppliers will resolve their
Year 2000 issues in a timely fashion.  However, if the Company or its material
suppliers do not become Year 2000 compliant, the Company could suffer a material
adverse effect on its business, results of operations and financial condition.
The Company believes that it is unlikely that any of these events will result,
but there can be no such assurance.  The Company has begun the development of a
contingency plan to address potential, unplanned failures within the Company and
external entities that could impact operations.  The Company currently
anticipates continuing development and refinement of the contingency plan
throughout the remainder of the current fiscal year.  The Company also will
continue to monitor any new issues or concerns relative to Year 2000.

                                                                              21

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Foreign Exchange Risk


        The Company manages foreign currency risk by attempting to increase
prices of products sold at or above the anticipated exchange rate of the local
currency relative to the U.S. dollar, by indexing certain of its accounts
receivable to exchange rates in effect at the time of their payment, and by
entering into foreign currency hedging instruments in certain instances and
utilizing natural hedges whenever possible. The Company consolidates the bulk of
its foreign exchange exposure related to intercompany transactions in its
International Financial Services Center ("IFSC") in Dublin, Ireland. These
transactional exposures are managed using various derivative alternatives
depending on the length and size of the exposure. For the quarter ended August
31, 1999, the Company had no material net foreign currency translation gains or
losses.

Derivative Financial Instruments

        The Company uses various derivative financial instruments as part of an
overall strategy to manage the Company's exposure to market risk associated with
interest rate and foreign currency exchange rate fluctuations. Today, the
Company uses foreign currency forward contracts which are short term in nature
(45 days to one year) to manage the foreign currency exchange rate risks
associated with transactions in the regular course of the Company's
international operations.  The Company does not hold or issue derivative
financial instruments for trading purposes.

        The risk of loss to the Company in the event of nonperformance by any
counterparty under derivative financial instrument agreements is not
significant. All counterparties are rated A or higher by Moody's and Standard
and Poor's. Although the derivative financial instruments expose the Company to
market risk, fluctuations in the value of the derivatives are mitigated by
expected offsetting fluctuations in the matched instruments.

        The major currency exposures hedged by the Company are the Brazilian
real, British pound, Taiwan dollar, Dutch guilder, Euro and Polish zloty. The
contract amount of foreign currency forwards at August 31, 1999 and September
30, 1999 was $26.6 million and $7.5 million, respectively. The mark to market
value of foreign currency forwards at August 31, 1999 at September 30, 1999 were
not material.

Interest Rate Risk

        The interest rate of the Company's Facility is an index rate at the time
of borrowing plus an applicable margin on certain borrowings. The interest rate
is based on either the agent bank's prime lending rate or the London Interbank
Offered Rate. Additionally, the applicable margin is subject to increases as the
Company's ratio of consolidated funded debt to consolidated cash flow increases.
During the twelve months ended September 30, 1999, the interest rates of
borrowings under the Facility ranged from 6.45% to 8.50%. The Company manages
its borrowings under the Facility each business day to minimize interest
expense.

        The borrowings of the Company's Brazilian operations are short-term in
nature, typically less than six months.  Through November 30, 1998, annual rates
on borrowings by the Brazilian joint venture operations ranged from
approximately 36% to 48%.  As a result of the devaluation of the Brazilian real

                                                                              22

against the U.S. dollar in January 1999, annual interest rates for the Brazilian
borrowings increased in the first half of 1999 but have now declined to 21.5% to
29.9% at September 30, 1999. The Brazilian borrowings, including accrued
interest, at September 30, 1999 were $11.3 million. The Company continues to
evaluate financing alternatives to reduce interest expense for its Brazilian
operations.

     The Company's $150.0 million in long-term debt has a fixed coupon interest
rate of 5.0%.

                          PART II - OTHER INFORMATION


Item 1. Legal Proceedings

        During the period from May 1999 through July 1999, seven purported class
action lawsuits were filed in the United States District Court for the Southern
District of Florida, styled as follows: (1) Elfie Echavarri v. CellStar
Corporation, Alan H. Goldfield, Richard M. Gozia, and Mark Q. Huggins; (2)  Mark
Krug v. CellStar Corporation, Alan H. Goldfield, Richard M. Gozia and Mark Q.
Huggins; (3) Jewell Wright v. CellStar Corporation, Alan H. Goldfield, Richard
M. Gozia and Mark Q. Huggins; (4) Theodore Weiss v. CellStar Corporation, Alan
H. Goldfield, Richard M. Gozia and Mark Q. Huggins: (5) Tony LaBella v. CellStar
Corporation, Alan H. Goldfield, Richard M. Gozia and Mark Q. Huggins; (6) Thomas
F. Petrone v. CellStar Corporation, Alan H. Goldfield, Richard M. Gozia and Mark
Q. Huggins; and (7) Adele Brody v. CellStar Corporation, Alan H. Goldfield,
Richard M. Gozia and Mark Q. Huggins. Each of the above lawsuits seeks
certification as a class action to represent those persons who purchased the
publicly traded securities of the Company during the period from March 19, 1998
to September 21, 1998. Each of these lawsuits alleges that the Company issued a
series of materially false and misleading statements concerning the Company's
results of operations and the Company's investment in Topp, resulting in
violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934,
as amended, and Rule 10(b)(5) promulgated thereunder. The Court entered an order
on September 26, 1999 consolidating the above lawsuits and appointing lead
plaintiffs and lead plaintiffs' counsel. The lead plaintiffs have expressed
their intention to file a consolidated complaint. The Company believes that it
has complied with all reporting requirements with respect to its result of
operations and investment in Topp and that it has meritorious defenses to these
allegations and intends to vigorously defend the consolidated action.

        The Company is also a party to various other claims, legal actions and
complaints arising in the ordinary course of business.  Management believes that
the disposition of these other matters will not have a material adverse effect
on the consolidated financial condition or results of operations of the Company.

     Advances from time to time until and including the Business Day immediately
     preceding the Termination Date and not thereafter, in an aggregate

     shall bear interest prior to maturity at a rate per annum equal to the

          (c)  The Borrower may request Swing Line Advances by giving written
     notice to the Administrative Agent.  Such notice shall be irrevocable and
     must be received by the Administrative Agent prior to 2:00 P.M. Dallas,
     Texas time for Swing Line Advances to be made by crediting the account of
     Borrower maintained with the Administrative Agent and prior to 1:00 P.M.
     Dallas, Texas time for Swing Line Advances to be made by wire transfer, in
     either case on the same Business Day as the requested date of the Swing

     by means of an Advance Request Form, specifying (i) the requested date of
     such Swing Line Advance (which shall be a Business Day), and (ii) the
     amount of the requested Swing Line Advance, which shall be in a minimum
     amount of $100,000.  The proceeds of such Swing Line Advance will be made

     crediting the account of the Borrower maintained with the Administrative
     Agent with such proceeds or by wire transfer in accordance with written
     instructions from the Borrower.  Notwithstanding anything to the contrary
     contained herein, the Borrower may, at any time and from time to time,
     prepay the aggregate amount of outstanding Swing Line Advances, in whole or
     in part, without premium or penalty, by giving the Administrative Agent at
     least one Business Day advance irrevocable notice of the date and amount of
     prepayment.  If any such notice is given, the amount specified in such
     notice shall be due and payable on the date specified therein.

          (d)  Notwithstanding anything herein to the contrary, the
     Administrative Agent shall not fund any Swing Line Advances if the
     conditions set forth in Article VII have not been satisfied.
                             -----------

          (e)  The Administrative Agent, at any time in its sole and absolute
     discretion, may, on  behalf of the Borrower (which hereby irrevocably
     directs the Administrative Agent to act on its behalf) request each Bank,
     by giving written notice to the Administrative Agent and each Bank, to make
     a Floating Rate Advance in an amount equal to such Bank's Commitment
     Percentage of the amount of the Swing Line Advances outstanding on the date
     such notice is given or such lesser amount as the Administrative Agent
     shall specify (the "Refunded Swing Line Advances").  Unless any of the
                         ----------------------------
     events described in Section 12.1(e) or 12.1(f) shall have occurred with
                         ---------------    -------
     respect to the Borrower (in which event the procedures specified in Section
                                                                         -------
     2.2(f) shall apply) each Bank shall make the proceeds of its Advance
     ------
     available to the Administrative Agent at its Principal Office prior to
     12:00 noon (Dallas, Texas time) in funds immediately available on the
     Business Day next succeeding the date such notice is given.  The proceeds
     of such Floating Rate Advances shall be immediately applied to repay the
     Refunded Swing Line Advances.  Effective on the day such Floating Rate
     Advances are made, the portion of the Swing Line Advances so paid shall no
     longer be outstanding as Swing Line Advances, and shall be due under the
     respective Revolving Credit Notes payable to the Banks in accordance with
     their respective Commitment Percentages.

          (f)  If prior to the making of an Advance pursuant to Section 2.2(e)
                                                                --------------
     one of the events described in Section 12.1(e) or 12.1(f) shall have
                                    ---------------    -------
     occurred and be continuing with respect to the Borrower, each Bank will, on
     the date such Advance was to have been made

     pursuant to Section 2.2(e), purchase an undivided participating interest in
                 -------------
     the Refunded Swing Line Advances in an amount equal to (i) its Commitment
     Percentage times (ii) the Refunded Swing Line Advances. Each Bank will
                -----
     immediately transfer to the Administrative Agent, in immediately available
     funds, the amount of its participation. Thereafter, all payments of
     principal and interest on the Refunded Swing Line Advances shall be made to
     and distributed to the Banks by the Administrative Agent.

          (g)  Whenever, at any time after any Bank has purchased a
     participating interest in a Swing Line Advances, the Administrative Agent
     receives any payment on account thereof, the Administrative Agent will
     distribute to such Bank its participating interest in such amount
     (appropriately adjusted, in the case of interest payments, to reflect the
     period of time during which such Bank's participating interest was
     outstanding and funded); provided, however, that in the event that such
                              --------  -------
     payment received by the Administrative Agent is thereafter recovered from
     the Administrative Agent in connection with any bankruptcy or insolvency
     proceeding of the Borrower or otherwise, such Bank will return to the
     Administrative Agent any portion thereof previously distributed by the
     Administrative Agent to it.

          (h)  Each Bank's obligation to make the Advances referred to in
     Section 2.2(e) and to purchase participating interests pursuant to Section
     --------------                                                     -------
     2.2(f) shall be absolute and unconditional and shall not be affected by any
     ------
     circumstance, including without limitation (i) any setoff, counterclaim,
     recoupment, defense or other right which such Bank or the Borrower may have
     against the Administrative Agent, the Borrower or any other Person for any
     reason whatsoever; (ii) the occurrence or continuance of a Default or an
     Event of Default; (iii) any adverse change in the condition (financial or
     otherwise) of the Borrower; (iv) any breach of this Agreement or any other
     Loan Documents by the Borrower, any Guarantor or any other Bank; or (v) any
     other circumstance, happening or event whatsoever, whether or not similar
     to any of the foregoing; provided, however, that (x) the Banks' obligations
                              --------  -------
     under Section 2.2(e) shall be subject to the minimum amounts specified in
           --------------
     Section 2.6 so long as no Default or Event of Default is continuing, and
     -----------
     (y) no Bank shall be required to make an Advance or purchase a
     participating interest in a Swing Line Advance that would cause the
     aggregate amount of such Bank's Advances, participations in Swing Line
     Advances and share of Letter of Credit Liabilities to exceed its Commitment
     under this Agreement.

     Section 2.3.  Notes.  The obligation of the Borrower to repay each Bank
                   -----
for Advances made by such Bank and interest thereon shall be evidenced by a
Revolving Credit Note executed by the Borrower, payable to the order of such
Bank, in the principal amount of such Bank's Commitment as in effect on the date
hereof, and dated the date hereof.  The obligation of the Borrower to repay the
Administrative Agent for Swing Line Advances made by the Administrative Agent
and interest thereon shall be evidenced by a Swing Line Note executed by the
Borrower, payable to the order of the Administrative Agent, in the principal
amount of the Swing Line Commitment as in effect on the date hereof, and dated
the date hereof.

     Section 2.4.  Repayment of Advances.  The Borrower shall repay the
                   ---------------------
unpaid principal amount of all Advances on the Termination Date.

     Section 2.5.  Interest.  The unpaid principal amount of the Advances
                   --------
shall bear interest prior to maturity at a varying rate per annum equal from day
to day to the lesser of (a) the Maximum Rate, or (b) the Applicable Rate.
Interest on the Eurodollar Advances and Alternate Currency Advances shall be
computed on the basis of a year of 360 days and the actual number of days
elapsed; provided that, in the case of Advances denominated in any Alternate
Currency in respect of which the Alternate Currency Agent has determined that a
365-day basis is standard market practice in the applicable interbank market,
interest shall be calculated on the basis of a year of 365 days and the actual
number of days elapsed.  Interest on the Floating Rate Advances shall be
computed on the basis of a year of 360 days and the actual number of days
elapsed at all times when the Alternate Base Rate is based on the Federal Funds
Effective Rate and a year of 365 or 366 days, as the case may be, and the actual
number of days elapsed at all times when the Alternate Base Rate is the Prime
Rate.  If at any time the Applicable Rate for any Advance shall exceed the
Maximum Rate, thereby causing the interest accruing on such Advance to be
limited to the Maximum Rate, then any subsequent reduction in the Applicable
Rate for such Advance shall not reduce the rate of interest on such Advance
below the Maximum Rate until the aggregate amount of interest accrued on such
Advance equals the aggregate amount of interest which would have accrued on such
Advance if the Applicable Rate had at all times been in effect. Accrued and
unpaid interest on the Advances shall be due and payable as follows:

             (i)   in the case of Floating Rate Advances, on each Quarterly
     Payment Date;

             (ii)  in the case of each Eurodollar Advance and each Alternate
     Currency Advance, on the last day of the Interest Period with respect
     thereto;

             (iii) upon the payment or prepayment of any Advance or the
     Conversion of any Advance to an Advance of another Type (but only on the
     principal amount so paid, prepaid, or Converted); and

             (iv)  on the Termination Date.

All past due principal and interest shall bear interest at the Default Rate.
Interest payable at the Default Rate shall be payable from time to time on
demand.

     Section 2.6.  Borrowing Procedure.  The Borrower shall give the
                   -------------------
Administrative Agent notice of each requested Advance (other than Swing Line
Advances and Alternate Currency Advances), and shall give the Alternate Currency

(which shall be a Business Day), (ii) the amount of such Advance, (iii) the Type

Alternate Currency, it being agreed that Advances made on any one day shall be
made in the same currency, and (v) in the case of a Eurodollar Advance or an
Alternate Currency Advance, the duration of the Interest Period for such
Advance. The Agent at its option may accept telephonic requests for Advances,
provided that such acceptance shall not constitute a waiver of the Agent's right
to delivery of an Advance Request Form in connection with subsequent Advances.
Any telephonic request for an Advance by the Borrower shall be promptly
confirmed by submission of a properly completed Advance Request Form to the
Agent. Each Advance (other than Swing Line Advances) shall be in a minimum
principal amount of $1,000,000 or the Equivalent Amount thereof or such greater
amount which is an integral multiple of $100,000 or the Equivalent Amount
thereof. The aggregate principal amount of Eurodollar Advances having the same
Interest Period shall be at least equal to $1,000,000. The aggregate principal
amount of Alternate Currency Advances having the same Interest Period shall be
at least equal to the Equivalent Amount of $1,000,000. The Agent shall notify
each Bank of the contents of each such notice on the day such notice is received
by the Agent if received by 11:00 A.M. Dallas, Texas time (or 11:00 A.M. London
time in the case of Alternate Currency Advances) on a Business Day and otherwise
on the next succeeding Business Day. Promptly on the date specified for each
Advance hereunder, each Bank will make available to the Agent at the Principal
Office of the Administrative Agent or, as to Alternate Currency Advances, at the

payment of any amount of Euro Units or National Currency Units, such amounts

Frankfurt am Main, Germany (or such other principal financial center in such
Participating Member State as the Alternate Currency Agent may from time to time
nominate for this purpose) as the Alternate Currency Agent shall from time to
time nominate for this purpose. After the Agent's receipt of such funds and
subject to the terms and conditions of this Agreement, the Agent will (a) make
each Advance (other than Alternate Currency Advances) available to the Borrower
by depositing the same, in Dollars in immediately available funds, in an account
of the Borrower maintained with the Agent designated by the Borrower or by wire
transfer in accordance with written instructions from the Borrower, (b) make
each Alternate Currency Advance (other than Advances in Euro Units) available to
the Borrower by depositing the same, in the requested Alternate Currency in
immediately available funds, in an account of the Borrower maintained with a
financial institution in the country where such Alternate Currency is legal
tender, and (c) make each Advance in Euro Units available by depositing the same
in an account of the Borrower maintained with a financial institution in
Frankfurt am Main, Germany; in each case designated by the Borrower by written
notice to the Agent containing the information specified in Exhibit L hereto for

Conversions to Floating Rate Advances, no Conversions shall be made while a
Default or Event of Default has occurred and is continuing and no Continuations
of any Eurodollar Advances or any Alternate Currency Advances shall be made
while a Default or an Event of Default has occurred and is continuing, unless

Dallas, Texas time (or 11:00 A.M. London time in the case of Alternate Currency
Advances) on the day which is not less than the number of Business Days
specified above for such notice.  If the Borrower shall fail to give the Agent
the notice as specified above for Continuation or Conversion of a Eurodollar
Advance prior to the end of the Interest Period with respect thereto, such
Eurodollar Advance shall automatically be Converted into a Floating Rate Advance
on the last day of the Interest Period for such Eurodollar Advance.  If Borrower
shall fail to give the Agent notice as specified above for the Continuation or
Conversion of an Alternate Currency Advance prior to the end of the Interest
Period with respect thereto, such Alternate Currency Advance shall be Continued
for an Interest Period of one month; provided, however, that no Alternate

occurred and continuing but in such event shall instead be Converted to a
Floating Rate Advance in Dollars at the end of the applicable Interest Period.

                   ---------------

than CBT and Chase shall be deemed utilized by the amount of all outstanding
Advances of such Banks (which shall not include Swing Line Advances) and all
Letter of Credit Liabilities of such Banks, and (b) the Commitment of CBT shall
be deemed utilized by the amount of all outstanding Advances of CBT, all
outstanding Swing Line Advances of CBT, all Letter of Credit Liabilities of CBT
and all Alternate Currency Advances of Chase. Accrued commitment fees shall be

Administrative Agent, solely for its own account, an administrative fee as
provided in the Fee Letter.

     Section 2.12.  Commitment Increase.  The parties hereto understand that
                    -------------------
the Borrower may seek one or more financial institutions to take a Commitment or
Commitments in the aggregate amount of $20,000,000 (the "Commitment Increase").
                                                         -------------------
The Commitment Increase may be taken by any existing Bank hereunder by
increasing the Commitment of such existing Bank (each an "Increasing Bank") or
                                                          ---------------
by a new Bank added as a party hereto (each an "Additional Bank"), subject to
                                                ---------------
the conditions hereinafter specified.  For purposes of the foregoing, Agent may,
from time to time, (i) admit Additional Banks hereunder, or (ii) at the request
of any Increasing Bank, increase the Commitment of such Increasing Bank, subject
to the following conditions:

(a)  each Additional Bank shall be an Eligible Assignee;

(b)  Borrower shall execute (i) a new Revolving Credit Note payable to the order
of each Additional Bank, or (ii) a replacement Revolving Credit Note payable to
the order of each Increasing Bank;

(c)  Borrower and Agent shall execute appropriate documentation to add each
Additional Bank as a party to this Agreement, whereupon such Additional Bank
shall have all of the rights and obligations of a Bank hereunder and under the
other Loan Documents;

                                      -35-
<PAGE>

(d)  Each Additional Bank and each Increasing Bank shall pay to the Agent for
the account of the other Banks an amount equal to its Percentage Commitment of
outstanding Advances, and such amount so paid shall constitute an Advance by
such Additional Bank or Increasing Bank under its Note and a payment of
principal to the other Banks under their respective Notes, and the outstanding
principal balances of the respective Notes shall be increased or reduced
accordingly;

(e)  After giving effect to the admission of any Additional Bank or the increase
in the Commitment of any Increasing Bank, the Total Commitment Amount shall not
exceed $135,000,000; and

(f)  No admission of any Additional Bank shall increase the Commitment of any
     existing Bank.

Upon and as of the date of the addition of any Additional Bank to the Agreement
or the increase of the Commitment of any Increasing Bank, (i) the Commitments of
the other Banks shall remain unchanged, and the respective Commitment
Percentages and pro rata shares of such Banks shall be adjusted accordingly, and
(ii) each of the other Banks shall be deemed to have sold and transferred to
such Additional Bank or such Increasing Bank, as the case may be, and such
Additional Bank or Increasing Bank shall be deemed irrevocably and
unconditionally to have purchased and received from each such other Banks (on a
pro rata basis, based on such other Banks' respective Commitment Percentages, as
adjusted in accordance with this Section) a portion of such other Banks'
participation shares under Section 3.3 in all Letters of Credit outstanding on
                           -----------

Bank's or such Increasing Bank's Commitment Percentage of such outstanding
Letters of Credit.  The addition of any Additional Bank or the increase of the
Commitment of an Increasing Bank and the effects thereof as described in this
Section shall occur automatically upon satisfaction of the conditions specified
above, without the necessity for further documentation to be executed by the
other Banks.  None of the Agent, the Syndication Agent, the Documentation Agent,
Chase, CBT or any other Bank or any of their respective Affiliates shall have
any obligation to find or arrange for any Additional Bank, and no Bank shall
have any obligation to increase its Commitment.

     Section 2.13.  Amendment Fees.  The Borrower agrees to pay to the
                    --------------
Administrative Agent for the account of each Bank an amendment fee as provided

     Section 3.1.  Letters of Credit.  Subject to the terms and conditions
                   -----------------
of this Agreement, the Administrative Agent agrees to issue one or more Letters
of Credit denominated and payable in Dollars for the account of the Borrower
from time to time from the date hereof to and including the Termination Date;
provided, however, that the outstanding Letter of Credit Liabilities shall not
- --------  -------
at any time exceed, and the Administrative Agent shall not be obligated to issue
any Letter of Credit which would cause the outstanding Letter of Credit
Liabilities to exceed, the lesser of (a) $30,000,000 or (b) an amount equal to
(i) the lesser of the Total Commitment Amount or the Borrowing Base, minus (ii)
the outstanding Advances, except as permitted by Section 4.3.  Each Letter of

Credit may be

                                      -36-
<PAGE>

issued for the account of or used by the Borrower or any Subsidiary of the
Borrower (including the Partnerships), but the Borrower shall have full
liability for each Letter of Credit. Each Letter of Credit shall have an
expiration date not to exceed one year, shall not have an expiration date beyond
the Termination Date, shall be payable in Dollars, shall have a minimum face
amount of $50,000, must support a transaction that is entered into in the
ordinary course of the Borrower's or its Subsidiaries' business, must be

limitation, the Administrative Agent's standard application for issuance of
standby or commercial letters of credit, as the case may be, as then in effect
[each an "L/C Application"]) as the Administrative Agent may require
          ----------------
(collectively, the "L/C Documents"). A copy of the form of L/C Application which
                    -------------
is in effect as of the date hereof for standby letters of credit is attached
hereto as Exhibit I-1, and a copy of the form of L/C Application which is in
          -----------
effect as of the date hereof for commercial letters of credit is attached hereto
as Exhibit I-2. However, the form of L/C Application may be changed by the
   -----------
Administrative Agent from time to time without notice to the Borrower or the
Banks.

     Section 3.2.  Procedure for Issuing Letters of Credit.  Each Letter of
                   ---------------------------------------
Credit shall be issued on at least four Business Days prior notice from the
Borrower to the Administrative Agent by means of a Letter of Credit Request Form
describing the transaction proposed to be supported thereby and specifying (a)
the requested date of issuance  (which shall be a Business Day), (b) the face
amount of the Letter of Credit, (c) the expiration date of the Letter of Credit,
(d) the name and address of the beneficiary, and (e) the name and address of the
account party (which shall be the Borrower or a Subsidiary of the Borrower), (f)
the purpose for which such Letter of Credit will be used, and (g) the form of
the draft and any other documents required to be presented at the time of any
drawing (such notice to set forth the exact wording of such documents or to
attach copies thereof).  The Administrative Agent shall notify each Bank of the
contents of each such notice on the day such notice is received by
Administrative Agent if received by 11:00 A.M. Dallas, Texas time on a Business
Day and otherwise on the next succeeding Business Day.

     Section 3.3.  Participation by Banks.  Immediately upon the Administrative
                   ----------------------
Agent's issuance of any Letter of Credit on or after the date hereof, the
Administrative Agent shall be deemed to have sold and transferred to each Bank
(other than Chase) and each Bank (other than Chase) shall be deemed irrevocably
and unconditionally to have purchased and received from the Administrative
Agent, without recourse or warranty, an undivided interest and participation (to
the extent of such Bank's Commitment Percentage) in such Letter of Credit and
all applicable rights of the Administrative Agent in such Letter of Credit. The
Administrative Agent shall provide to each Bank (other than Chase) a copy of
each Letter of Credit issued on or after the date hereof, promptly after
issuance.

     Section 3.4.  Payments Constitute Advances.  Each payment by the
                   ----------------------------
Administrative Agent pursuant to a drawing under a Letter of Credit shall
constitute and be deemed a Floating Rate Advance by each Bank (other than Chase)
to the Borrower under such Bank's Revolving Credit Note and this Agreement as of
the day and time such payment is made by the Administrative Agent and in the
amount of such Bank's pro rata share of such payment.  Promptly on the date of
each payment by the Administrative Agent pursuant to a drawing under a Letter of
Credit and after receipt of notice

                                      -37-
<PAGE>

from the Administrative Agent as to the amount of such payment, each Bank (other
than Chase) will make available to the Administrative Agent at its Principal
Office in immediately available funds, such Bank's pro rata share of such
payment.

     Section 3.5.  Letter of Credit Fee.  The Borrower shall pay to the
                   --------------------
Administrative Agent for the account of the Banks (other than Chase) a
nonrefundable letter of credit fee with respect to standby Letters of Credit,
payable on the date each such Letter of Credit is issued in an amount equal to
the Applicable Percentage per annum of the face amount of such Letter of Credit,
for the period during which such Letter of Credit will remain outstanding.  The
letter of credit fee is based on a 365 or 366 day year, as the case may be, and
the actual number of days in the stated term of such Letter of Credit.  The
Borrower shall pay to the Administrative Agent for the account of the Banks
(other than Chase) a nonrefundable letter of credit fee with respect to
commercial Letters of Credit, payable on the date each such Letter of Credit is
issued, for the three month period following such issuance, and on the first day
of each succeeding three month period, if such Letter of Credit is outstanding
on such day.  Each such fee for commercial Letters of Credit shall be in an
amount equal to the Applicable Percentage per annum of the face amount of such
Letter of Credit, for each such entire three month period, regardless of whether
such Letter of Credit actually remains outstanding for such entire three month
period, and shall be calculated based on a 365 or 366 day year, as the case may
be.  The Borrower shall pay to the Administrative Agent, solely for its own
account, a nonrefundable issuance and fronting fee for each Letter of Credit in
an amount equal to one eighth of one percent per annum of the face amount of
such Letter of Credit, calculated on the basis of a year of 365 or 366 days, as
the case may be, and payable on the date each such Letter of Credit is issued.

     Section 3.6.  Administrative Agent's Responsibilities.  Administrative
                   ---------------------------------------
Agent agrees with each Bank that it will exercise and give the same care and
attention to each Letter of Credit as it gives to its other letters of credit.
Each Bank and the Borrower agree that, in paying any draft or draw under any
Letter of Credit, the Administrative Agent has no responsibility to obtain any
document (other than any documents expressly required by the respective Letter
of Credit) or to ascertain or inquire as to any document's validity,
enforceability, sufficiency, accuracy or genuineness or the authority of any
Person delivering it.  Neither the Administrative Agent nor any of its
representatives, directors, officers, employees, attorneys or agents shall be
liable to any Bank, the Borrower or any Subsidiary for any Letter of Credit's
use or for any beneficiary's acts or omissions.  The Administrative Agent shall
have no liability to the Borrower, any Subsidiary or any Bank for any action,
inaction, error, delay or omission taken or suffered by the Administrative Agent
or any of its representatives, directors, officers, employees, attorneys or
agents in connection with any Letter of Credit, applicable draws, drafts or
documents, or the transmission, dispatch or delivery of any related message or
advice, if done, taken or made in accordance with the L/C Documents.

     Section 3.7.  Letter of Credit Documents.  Certain additional
                   --------------------------
provisions regarding the obligations, liabilities, rights, remedies and
agreements of the Borrower and the Administrative Agent relative to the Letters
of Credit shall be set forth in the L/C Documents.  The terms of this Agreement
shall control any express conflict between the terms of this Agreement and the
terms of any L/C Application.

     Section 4.1.  Method of Payment.  All payments of principal, interest,
                   -----------------
and other amounts to be made by the Borrower under this Agreement and the other
Loan Documents (other than payments of principal and interest with respect to
Alternate Currency Advances) shall be made to the Administrative Agent at its
Principal Office in Dollars and immediately available funds, without setoff,
deduction, or counterclaim, not later than 11:00 A.M., Dallas, Texas time on the
date on which such payment shall become due (each such payment made after such
time on such due date to be deemed to have been made on the next succeeding
Business Day).  All payments of principal and interest to be made by the
Borrower under this Agreement and the other Loan Documents with respect to
Alternate Currency Advances shall be made to the Alternate Currency Agent, in
such Alternate Currency and immediately available funds, without setoff,
deduction, or counterclaim, to such account at such bank, in the country where
such Alternate Currency is legal tender, as the Alternate Currency Agent may
designate to the Borrower, or as otherwise provided in Section 4.9.  Such
                                                       -----------
payments of principal and interest with respect to Alternate Currency Advances
shall be made no later than 11:00 A.M. local time in the place where such bank
is located on the date on which such payment shall become due (each such payment
made after such time on such due date to be deemed to have been made on the next
succeeding Business Day).  The Borrower shall, at the time of making each
payment under this Agreement and the other Loan Documents, specify to the Agent
the sums payable by the Borrower under this Agreement and the other Loan
Documents to which such payment is to be applied (and in the event the Borrower
fails to so specify, or if an Event of Default has occurred and is continuing,
the Agent may apply such payment to the Obligations in such order and manner as
it may elect in its sole discretion, subject to Section 4.4 hereof).  Each
                                                -----------
payment received by the Agent under this Agreement or any other Loan Document
for the account of a Bank shall be paid promptly to such Bank, in immediately
available funds, for the account of such Bank's Applicable Lending Office.
Whenever any payment under this Agreement or any other Loan Document shall be
stated to be due on a day that is not 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 the payment of interest and commitment
fee, as the case may be.  Each payment received by Agent hereunder or under any
Revolving Credit Note shall be paid promptly to the Banks in accordance with
Section 4.4, in immediately available funds, for the account of each Bank's
- -----------
Applicable Lending Office for the Advance in respect of which such payment is
made.

     Section 4.2.  Voluntary Prepayment.  The Borrower may prepay the
                   --------------------
Advances in whole at any time or from time to time in part without premium or
penalty but with accrued interest to the date of prepayment on the amount so
prepaid, provided that (a) the Borrower shall give the Agent at least five
Business Days' prior notice of any prepayment of Advances other than Floating
Rate Advances, (b) each partial prepayment of any Advances (excluding Swing Line
Advances) shall be in the principal amount of $1,000,000 or the Equivalent
Amount or such greater amount which is an integral multiple of $1,000,000 or the
Equivalent Amount, and (c) any and all amounts required pursuant to Section 5.5
                                                                    -----------
hereof shall be paid concurrently with such prepayment.  All notices under this
Section

                                      -39-
<PAGE>

shall be irrevocable and shall be given not later than 11:00 A.M. Dallas, Texas
time on the day which is not less than the number of Business Days specified
above for such notice.

     Section 4.3.  Mandatory Prepayment.  If at any time the amount equal to
                   --------------------
the sum of (i) the outstanding principal amount of the Advances (including
without limitation the Equivalent Amount of any Alternate Currency Advances),
plus (ii) the Letter of Credit Liabilities exceeds the lesser of the Borrowing
Base or the Total Commitment Amount (the amount of such excess being referred to
herein as the "Overadvance"), the Borrower shall promptly prepay the outstanding
               -----------
Advances by the amount of the Overadvance plus accrued and unpaid interest on
the amount so prepaid or, if no Advances are outstanding, the Borrower shall
immediately pledge to the Agent cash or cash equivalent investments in an amount
equal to the Overadvance as security for the Obligations; provided, however,
that in the event an Overadvance exists at the end of the Alternate Advance Rate
Availability Period solely due to the decrease in the Borrowing Base advance
                    ------
rate for Eligible Accounts to 80% or the decrease in the Borrowing Base advance
rate for Eligible Inventory to 50%, so long as no Default exists and is
continuing, (a) Borrower shall not be obligated to prepay the outstanding
Advances by the amount of such Overadvance or pledge cash or cash equivalents in
an amount equal to such Overadvance as security for the Obligations, (b) the
existence of such Overadvance shall not constitute a Default or Event of
Default, and (c) no Advances shall be made while such Overadvance exists.  The
period during which any such permitted Overadvance exists is referred to herein
as the "Permitted Overadvance Period."
        ----------------------------

     Section 4.4.  Pro Rata Treatment.  Except to the extent otherwise
                   ------------------
provided herein: (a) each Advance shall be made by the Banks under Section 2.1
                                                                   -----------

                     -----------                                     -----------
shall be made for the account of the Banks, each termination or reduction of the
Commitments under Section 2.10 shall be applied to the Commitments of the Banks,
                  ------------
and each Letter of Credit shall be deemed participated in by the Banks, pro rata
according to the amounts of their respective Commitments; (b) the making,
Conversion, and Continuation of Advances of a particular Type (other than
Conversions provided for by Section 5.4) shall be made pro rata among the Banks
                            -----------
holding Advances of such Type according to the amounts of their respective
Commitments; (c) each payment and prepayment of principal of or interest on
Advances by the Borrower of a particular Type shall be made to the Agent for the
account of the Banks holding Advances of such Type pro rata in accordance with
the respective unpaid principal amounts of such Advances held by such Banks; and
(d) Interest Periods for Advances of a particular Type shall be allocated among
the Banks holding Advances of such Type pro rata according to the respective
principal amounts held by such Banks.  For purposes of this Section 4.4, (i)
                                                            -----------
Chase's pro rata share of Alternate Currency Advances shall be determined as if
Chase held the entire Commitment of Chase and CBT; (ii) Chase shall not be
entitled to receive any commitment fees or letter of credit fees; (iii) each
reduction of the Commitments shall reduce CBT's Commitment on a pro rata basis
with the other Banks, with a corresponding reduction of Chase's commitment to
make Alternate Currency Advances, and (iv) Chase shall not participate in
Letters of Credit.

     Section 4.5.  Non-Receipt of Funds by the Agent.  Unless the Agent
                   ---------------------------------
shall have been notified by a Bank or the Borrower (the "Payor") prior to the
                                                         -----
date on which such Bank is to make payment

                                      -40-
<PAGE>

to the Agent of the proceeds of an Advance to be made by it hereunder or the
Borrower is to make a payment to the Agent for the account of one or more of the
Banks, as the case may be (such payment being herein called the "Required
                                                                 --------
Payment"), which notice shall be effective upon receipt, that the Payor does not
- -------
intend to make the Required Payment to the Agent, the Agent may assume that the
Required Payment has been made and may, in reliance upon such assumption (but
shall not be required to), make the amount thereof available to the intended
recipient on such date and, if the Payor has not in fact made the Required
Payment to the Agent, the recipient of such payment shall, on demand, pay to the
Agent the amount made available to it together with interest thereon in respect
of the period commencing on the date such amount was so made available by the
Agent until the date the Agent recovers such amount at a rate per annum equal to
the Federal Funds Effective Rate for such period.

     Section 4.6.  Withholding Taxes.  All payments by the Borrower of
                   -----------------
principal of and interest on the Advances and of all fees and other amounts
payable under any Loan Document are payable without deduction for or on account
of any present or future taxes, duties or other charges levied or imposed by the
United States of America or by the government of any jurisdiction outside the
United States of America or by any political subdivision or taxing authority of
or in any of the foregoing through withholding or deduction with respect to any
such payments, or otherwise with respect to any Alternate Currency Advances.  If
any such taxes, duties or other charges are so levied or imposed, the Borrower
will pay additional interest or will make additional payments in such amounts so
that every net payment of principal of and interest on the Advances and of all
other amounts payable by it under any Loan Document, after withholding or
deduction for or on account of any such present or future taxes, duties or other
charges, will not be less than the amount provided for herein or therein,
provided that the Borrower shall have no obligation to pay such additional
amounts to any Bank to the extent that such taxes, duties, or other charges are
levied or imposed by reason of the failure of such Bank to comply with the
provisions of Section 4.7.  The Borrower shall furnish promptly to the Agent for
              -----------
distribution to each affected Bank, as the case may be, official receipts
evidencing any such withholding or reduction and shall confirm that all
applicable taxes, if any, imposed on this Agreement or transactions hereunder
shall have been properly and legally paid by it to the appropriate taxing
authorities by sending official tax receipts or notarized copies of such
receipts to the Agent within 30 days after payment of any applicable tax.  The
Borrower agrees to cause all present and future taxes, duties or other charges
levied or imposed by the government of any jurisdiction outside the United
States of America or by any political substitution or taxing authority thereof
(including those to be paid on behalf of any Bank, if any) directly to the
appropriate Governmental Authority.  Upon written demand by the Agent, the
Borrower shall indemnify the Agent and the Banks and hold them harmless for the
full amount of such taxes, duties or other charges payable with respect to any
Alternate Currency Advance and any liabilities (including penalties, interest
and expenses) arising from such taxes.

     Section 4.7.  Withholding Tax Exemption.  Each 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 two duly completed
copies of United States Internal Revenue Service Form 1001 or 4224, certifying
in either case that such Bank is entitled to receive payments from the Borrower
under any Loan Document without deduction or withholding of any United States
federal income taxes.  Each

                                      -41-
<PAGE>

Bank which so delivers a Form 1001 or 4224 further undertakes to deliver to the
Borrower and the Agent two additional copies of such form (or a successor form)
on or before the date such form expires or becomes obsolete or after the
occurrence of any event requiring a change in the most recent form so delivered
by it, and such amendments thereto or extensions or renewals thereof as may be
reasonably requested by the Borrower or the Agent, in each case certifying that
such Bank is entitled to receive payments from the Borrower under any Loan
Document without deduction or withholding of any United States federal income
taxes, unless an event (including without limitation any change in treaty, law
or regulation) has occurred prior to the date on which any such delivery would
otherwise be required which renders all such forms inapplicable or which would
prevent such Bank from duly completing and delivering any such form with respect
to it and such Bank advises the Borrower and the Agent that it is not capable of
receiving such payments without any deduction or withholding of United States
federal income tax.

     Section 4.8.  Judgment Currency.  If, for the purposes of obtaining
                   -----------------
judgment in any court, it is necessary to convert a sum due from the Borrower
hereunder or under any of the Notes in the currency expressed to be payable
herein or under the Notes (the "Specified Currency") into another currency, the
                                ------------------
parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which in accordance with normal
banking procedures the Alternate Currency Agent could purchase the Specified
Currency with such other currency at the Principal Office of the Alternate
Currency Agent on the Business Day preceding that on which the final, non-
appealable judgment is given.  The obligations of the Borrower in respect of any
sum due to any Bank or the Agent hereunder or under any Note shall,
notwithstanding any judgment in a currency other than the Specified Currency, be
discharged only to the extent that on the Business Day following receipt by such
Bank or the Agent (as the case may be) of any sum adjudged to be so due in such
other currency such Bank or the Agent (as the case may be) may in accordance
with normal, reasonable banking procedures purchase the Specified Currency with
such other currency.  If the amount of the Specified Currency so purchased is
less than the sum originally due to such Bank or the Agent, as the case may be,
in the Specified Currency, the Borrower agrees, to the fullest extent that it
may effectively do so, as a separate obligation and notwithstanding any such
judgment, to indemnify such Bank or the Agent, as the case may be, against such
loss, and if the amount of the Specified Currency so purchased exceeds (a) the
sum originally due to any Bank or the Agent, as the case may be, in the
Specified Currency and (b) any amounts shared with the other Banks as a result
of allocations of such excess as a disproportionate payment to such Bank under
Section 13.3, such Bank or the Agent, as the case may be, agrees to remit such
- ------------
excess to the Borrower.  Without prejudice to the survival of any of the other
agreements of the Borrower hereunder, the agreements and obligations of the
Borrower under this Section 4.8 shall survive the termination of this Agreement
                    -----------
and the payment of all other amounts owing hereunder.

     Section 4.9.  EMU Provisions.
                   --------------

(a)  Effectiveness of Provisions.  If and to the extent that any of the
     ---------------------------
provisions of subsections (b) to (h) below (inclusive) relates to any state (or
              ---------------     -
the currency of such state) that is not a Participating Member State on the
Commencement of the Third Stage of EMU, such provision shall become

                                      -42-
<PAGE>

effective in relation to such state (and the currency of such state) at and from
the date on which such state becomes a Participating Member State.

(b)  Redenomination and Alternative Currencies.  Each obligation under
     -----------------------------------------
this Agreement of a party to this Agreement which has been denominated in the
National Currency Unit of a Participating Member State shall be redenominated
into the Euro Unit in accordance with EMU Legislation, provided, that if and to
the extent that any EMU Legislation provides that following the Commencement of
the Third Stage of EMU an amount denominated either in the Euro Unit or in the
National Currency Unit of a Participating Member State and payable within that
Participating Member State by crediting an account of the creditor can be paid
by the debtor either in the Euro Unit or in that National Currency Unit, each
party to this Agreement shall be entitled to pay or repay any such amount either
in the Euro Unit or in such National Currency Unit.

(c)  Advances. Any Advance in the currency of a Participating Member State shall
     --------
be made in the Euro Unit.

(d)  Payments to the Alternate Currency Agent.  Sections 2.6, 4.1 and
     ----------------------------------------   ------------  ---
13.3 shall be construed so that, in relation to the payment of any amount of
- ----
Euro Units or National Currency Units, such amount shall be made available to
the Alternate Currency Agent in immediately available, freely transferable,
cleared funds to such account with such bank in Frankfurt am Main, Germany (or
such other principal financial center in such Participating Member State as the
Alternate Currency Agent may from time to time nominate for this purpose) as the
Alternate Currency Agent shall from time to time nominate for this purpose.

(e)  Payments by the Alternate Currency Agent to the Banks.  Any amount
     -----------------------------------------------------
payable by the Alternate Currency Agent to the Banks under this Agreement in the
currency of a Participating Member State shall be paid in Euro Units.


(f)  Payments by the Alternate Currency Agent.  Generally, with respect
     ----------------------------------------
to the payment of any amount denominated in the Euro or in a National Currency
Unit, the Alternate Currency Agent shall not be liable to the Borrower or any of
the Banks in any way whatsoever for any delay, or the consequences of any delay,
in the crediting to any account of any amount required by this Agreement to be
paid by the Alternate Currency Agent if the Alternate Currency Agent shall have
taken all relevant steps to achieve, on the date required by this Agreement, the
payment of such amount in immediately available, freely transferable, cleared
funds (in the Euro Unit or, as the case may be, in a National Currency Unit) to
the account with the bank in the principal financial center in the Participating
Member State which the Borrower or, as the case may be, any Bank shall have
specified for such purpose. In this subsection (f), "all relevant steps" means
all such steps as may be prescribed from time to time by the regulations or
operating procedures of such clearing or settlement system as the Alternate
Currency Agent may from time to time determine for the purpose of clearing or
settling payments of the Euro.

(g)  Basis of Accrual. If the basis of accrual of interest or fees expressed in
     ----------------
this Agreement with respect to the currency of any state that is or becomes a
Participating Member State shall be

                                      -43-
<PAGE>

inconsistent with any convention or practice in the London Interbank Market or
any other applicable interbank market for the basis of accrual of interest or
fees in respect of the Euro, such convention or practice shall replace such
expressed basis effective as of and from the date on which such state becomes a
Participating Member State; provided, that if any Advance in the currency of
                            --------
such state is outstanding immediately prior to such date, such replacement shall
take effect, with respect to such Advance, at the end of the then current
Interest Period.

(h)  Rounding and Other Consequential Changes. Without prejudice and in addition
     ----------------------------------------
to any method of conversion or rounding prescribed by any EMU Legislation and
without prejudice to the respective liabilities for indebtedness of the Borrower
to the Banks and the Banks to the Borrower under or pursuant to this Agreement:

(i)  each reference in this Agreement to a minimum amount (or an integral
multiple thereof) in a National Currency Unit to be paid to or by the Alternate
Currency Agent shall be replaced by a reference to such reasonably comparable
and convenient amount (or an integral multiple thereof) in the Euro Unit as the
Alternate Currency Agent may from time to time specify; and

(ii) except as expressly provided in this Section 4.9, each provision of this
                                          -----------
Agreement shall be subject to such reasonable changes of construction as the
Alternate Currency Agent may from time to time specify to be necessary or
appropriate to reflect the introduction of or changeover to the Euro in
Participating Member States.

(i)  Increased Costs. The Borrower shall from time to time, at the request of
     ---------------
the Alternate Currency Agent, pay to the Alternate Currency Agent for the
account of each Bank the amount of any cost or increased cost incurred by, or of
any reduction in any amount payable to or in the effective return on its capital
to, or of interest or other return foregone by, such Bank or any holding company
of such Bank as a result of the introduction of, changeover to or operation of
the Euro in any Participating Member State.

     Section 4.10.  Continuity of Contract.  Except as otherwise provided
                    ----------------------
herein, no implementation of the EMU or change in currency nor any economic
consequences resulting therefrom shall (i) give rise to any right to terminate
prematurely, contest, cancel, rescind, alter, modify or renegotiate the
provisions of this Agreement or (ii) discharge, excuse or otherwise affect the
performance of any obligations of the Borrower under this Agreement or other
Loan Documents.

                  ----------------

             (a)  The Borrower shall pay directly to each Bank from time to time
     such amounts as such Bank may determine to be necessary to compensate it
     for any costs incurred by such Bank which such Bank determines are
     attributable to its making or maintaining of any

     Eurodollar Advances or any Alternate Currency Advances hereunder or its
     obligation to make such Advances hereunder, or any reduction in any amount
     receivable by such Bank hereunder in respect of any such Advances or such
     obligation (such increases in costs and reductions in amounts receivable
     being herein called "Additional Costs"), resulting from any Regulatory
                          ----------------
     Change which:

               (i)   changes the basis of taxation of any amounts payable to
          such Bank under this Agreement or its Note in respect of any
          Eurodollar Advances or any Alternate Currency Advances (other than
          taxes imposed on the overall net income of such Bank or its Applicable
          Lending Office for any Eurodollar Advances or any Alternate Currency
          Advances by the jurisdiction in which such Bank has its principal
          office or such Applicable Lending Office);

               (ii)  imposes or modifies any reserve, special deposit, minimum
          capital, capital ratio, or similar requirement relating to any
          extensions of credit or other assets of, or any deposits with or other
          liabilities or commitments of, such Bank (including (A) any Eurodollar
          Advances or any deposits referred to in the definition of "Eurodollar
          Rate" in Section 1.1 hereof or (B) any Alternate Currency Advances or
                   -----------
          any deposits referred to in the definition of "Alternate Currency
          Rate" in Section 1.1 hereof); or
                   -----------

               (iii) imposes any other condition affecting this Agreement or its
          Note or any of such extensions of credit or liabilities or
          commitments.

     Each Bank will notify the Borrower (with a copy to the Agent) of any event
     occurring after the date of this Agreement which will entitle such Bank to
     compensation pursuant to this Section 5.1(a) as promptly as practicable
                                   --------------
     after it obtains knowledge thereof and determines to request such
     compensation, and will designate a different Applicable Lending Office for
     Eurodollar Advances or Alternate Currency Advances if such designation will
     avoid the need for, or reduce the amount of, such compensation and will
     not, in the sole opinion of such Bank, violate any law, rule, or regulation
     or be in any way disadvantageous to such Bank, provided that such Bank
     shall have no obligation to so designate an Applicable Lending Office
     located outside the United States of America.  Each Bank will furnish to
     the Borrower, within 180 days after the occurrence of the event resulting
     in Additional Costs, a certificate setting forth the basis and the amount
     of each request of such Bank for compensation under this Section 5.1(a).
                                                              --------------

     5.1(a), the Borrower may, by notice to such Bank (with a copy to Agent),
     ------
     suspend the obligation of such Bank to make or Continue making, or Convert
     Advances into, Eurodollar Advances or Alternate Currency Advances until the
     Regulatory Change giving rise to such request ceases to be in effect (in
     which case the provisions of Section 5.4 hereof shall be applicable) and
                                  -----------

     any Alternate Currency Advance into a Floating Rate Advance which is funded
     in Dollars, subject to the provisions of Section 5.5.

             (b)   Without limiting the effect of the foregoing provisions of
     this Section 5.1, in the event that, by reason of any Regulatory Change,
          -----------
     any Bank either (i) incurs Additional Costs based on or measured by the
     excess above a specified level of the amount of a category of deposits or
     other liabilities of such Bank which includes deposits by reference to
     which the interest rate on Eurodollar Advances or Alternate Currency
     Advances is determined as provided in this Agreement or a category of
     extensions of credit or other assets of such Bank which includes Eurodollar
     Advances or Alternate Currency Advances or (ii) becomes subject to
     restrictions on the amount of such a category of liabilities or assets
     which it may hold, then, if such Bank so elects by notice to the Borrower
     the obligation of such Bank to make or Continue making, or Convert Advances
     into, Eurodollar Advances or Alternate Currency Advances hereunder shall be
     suspended until such Regulatory Change ceases to be in effect (in which
     case the provisions of Section 5.4 hereof shall be applicable).

     maintaining its obligations to make Advances or of making or maintaining
     Advances or on amounts receivable by it in respect of Advances, and of the
     additional amounts required to compensate such Bank in respect of any
     Additional Costs, shall be conclusive, provided that such determinations
     and allocations are made on a reasonable basis.

     Section 5.2.  Limitation on Types of Advances. Anything herein to the
                   -------------------------------
contrary notwithstanding, if with respect to any Eurodollar Advances or any
Alternate Currency Advances for any Interest Period therefor:

             (a)   The Agent determines (which determination shall be
     conclusive) that quotations of interest rates for the relevant deposits
     referred to in the definitions of "Eurodollar Rate" and "Alternate Currency
     Rate" in Section 1.1 hereof are not being provided in the relative amounts
              -----------
     or for the relative maturities for purposes of determining the rate of
     interest for such Advances as provided in this Agreement; or

             (b)   Required Banks determine (which determination shall be
     conclusive) that the relevant rates of interest referred to in the
     definitions of "Eurodollar Rate" and "Alternate Currency Rate" in Section
                                                                       -------
     1.1 hereof on the basis of which the rate of interest for such Advances for
     ---
     such Interest Period is to be determined do not accurately reflect the cost
     to the Banks of making or maintaining such Advances for such Interest
     Period; or

             (c)   There occurs on or before the date an Alternate Currency
     Advance is to be made any material adverse change in national or
     international financial, political or economic conditions or currency
     exchange rates or exchange controls which would in the opinion of Agent
     make it impracticable for the Alternate Currency Advance to be denominated
     in the Alternate Currency specified by the Borrower;

then the Agent shall give the Borrower prompt notice thereof specifying relevant
amounts or periods, and so long as such condition remains in effect, the Banks
shall be under no obligation to make

                                      -46-

additional Eurodollar Advances or Alternate Currency Advances or to Convert
Floating Rate Advances into Eurodollar Advances or Alternate Currency Advances,
and the Borrower shall, (i) on the last day(s) of the then current Interest
Period(s) for the outstanding Eurodollar Advances, either prepay such Eurodollar
Advances or Convert such Eurodollar Advances into Floating Rate Advances in
accordance with the terms of this Agreement, and (ii) either prepay such
Alternate Currency Advances or Convert such Alternate Currency Advances into
Floating Rate Advances funded in Dollars in accordance with the terms of this
Agreement.

     Section 5.3.  Illegality.  Notwithstanding any other provision of this
                   ----------
Agreement, in the event that it becomes unlawful for any Bank or its Applicable
Lending Office to (a) honor its obligation to make Eurodollar Advances or
Alternate Currency Advances hereunder or (b) maintain Eurodollar Advances or
Alternate Currency Advances hereunder, then such Bank shall promptly notify the
Borrower (with a copy to the Agent) thereof and such Bank's  obligation to make
or maintain Eurodollar Advances or Alternate Currency Advances and to Convert
Floating Rate Advances into Eurodollar Advances or Alternate Currency Advances
hereunder shall be suspended until such time as such Bank may again make and
maintain Eurodollar Advances or Alternate Currency Advances (in which case the
provisions of Section 5.4 hereof shall be applicable).
              -----------

     Section 5.4.  Substitute Floating Rate Advances.  If the obligation of
                   ---------------------------------
any Bank to make Eurodollar Advances or Alternate Currency Advances shall be
suspended pursuant to Section 5.1 or 5.3 hereof, all Advances which would be
                      -----------    ---
otherwise made by such Bank as Eurodollar Advances or Alternate Currency
Advances shall be made instead as Floating Rate Advances in Dollars and all
Advances which would otherwise be Converted into Eurodollar Advances or any
Alternate Currency Advances shall be Converted instead into (or shall remain as)
Floating Rate Advances in Dollars (and, if an event referred to in Section
                                                                   -------
5.1(b) or 5.3 hereof has occurred and  such Bank so requests by notice to the

Borrower (with a copy to the Agent), all Eurodollar Advances and all Alternate
Currency Advances of such Bank then outstanding shall be automatically Converted
into Floating Rate Advances in Dollars on the date specified by such Bank in
such notice) and, to the extent that Eurodollar Advances and Alternate Currency
Advances are so made as (or Converted into) Floating Rate Advances, all payments
and prepayments of principal which would otherwise be applied to such Bank's
Eurodollar Advances or Alternate Currency Advances shall be applied instead to
its Floating Rate Advances.

     Section 5.5.  Compensation.  The Borrower shall pay to the Agent for the

account of each Bank, upon the request of such Bank through the Agent, such
amount or amounts as shall be sufficient (in the reasonable opinion of such
Bank) to compensate it for any loss, cost, or expense incurred by it as a result
of:

             (a)   Any payment, prepayment or Conversion of a Eurodollar Advance
     or an Alternate Currency Advance for any reason (including, without
     limitation, the acceleration of outstanding Advances pursuant to Section
                                                                      -------
     12.2) on a date other than the last day of an Interest Period for such
     ----
     Advance; or

                                      -47-
<PAGE>

             (b)   Any failure by the Borrower for any reason (including,
     without limitation, the failure of any conditions precedent specified in
     Article VII to be satisfied) to borrow, Convert, or prepay a Eurodollar
     -----------
     Advance or an Alternate Currency Advance on the date for such borrowing,
     Conversion, or prepayment, specified in the relevant notice of borrowing,
     prepayment, or Conversion under this Agreement; or

             (c)   Any failure to pay any Alternate Currency Advance in the
     Alternate Currency in which it was made.

Without limiting the effect of the preceding sentence, such compensation shall
include, without limitation, (i) an amount equal to the excess, if any, of (1)
the amount of interest which otherwise would have accrued on the principal
amount so paid or Converted or not borrowed for the period from the date of such
payment, Conversion, or failure to borrow to the last day of the Interest Period
for such Advance (or, in the case of a failure to borrow, the Interest Period
for such Advance which would have commenced on the date specified for such
borrowing) at the applicable rate of interest for such Advance provided for
herein over (2) the interest component of the amount such Bank would have bid in
the London interbank market for Dollar deposits (or deposits in the applicable
Alternate Currency) of leading banks and amounts comparable to such principal
amount and with maturities comparable to such period, (ii) any loss or
reasonable expense sustained or incurred in liquidating or employing deposits
from third Persons acquired to effect or maintain such Alternate Currency
Advance or Eurodollar Advance or any part thereof, (iii) any loss incurred in
liquidating or closing out any foreign currency contract undertaken by such Bank
in funding and maintaining such Alternate Currency Advance, and (iv) any loss
arising from any change in the value of Dollars in relation to any such
Alternate Currency Advance which was not paid on the date due between the date
such payment was due and the date of payment, or which was not paid in the
Alternate Currency in which it was made, all as determined by such Bank in its
good faith discretion.

     Section 5.6.  Capital Adequacy.  If after the date hereof, the Agent or
                   ----------------
any Bank shall have determined that any Regulatory Change or compliance by the
Agent or such Bank (or its parent) with any guideline, request, or directive
regarding capital adequacy (whether or not having the force of law) of any such
central bank or other Governmental Authority, has or would have the effect of
reducing the rate of return on the Agent's or such Bank's (or their respective
parent's) capital as a consequence of its obligations hereunder or the
transactions contemplated hereby to a level below that which the Agent or such
Bank (or their respective parent) could have achieved but for such Regulatory
Change or compliance (taking into consideration the Agent's or such Bank's
policies with respect to capital adequacy) by an amount deemed by the Agent or
such Bank to be material, then from time to time, within 10 Business Days after
demand by the Agent or such Bank (with a copy to the Agent), the Borrower shall
pay to the Agent or such Bank (or their respective parent) such additional
amount or amounts as will compensate the Agent or such Bank for such reduction.
The Agent or such Bank will furnish to the Borrower, within 180 days after such
Bank actually incurs such reduction in its rate of return, a certificate of the
Agent or such Bank claiming compensation under this Section and setting forth
the basis and the additional amount or amounts to be paid to it hereunder.  Each
such certificate shall be conclusive, provided that the determination of such
amount

                                      -48-
<PAGE>

or amounts is made on a reasonable basis. In determining such amount or amounts,
the Agent or such Bank may use any reasonable averaging and attribution methods.

     Section 5.7.  Additional Costs in Respect of Letters of Credit.  If as a
                   ------------------------------------------------
result of any Regulatory Change there shall be imposed, modified, or deemed
applicable any tax, reserve, special deposit, or similar requirement against or
with respect to or measured by reference to Letters of Credit issued or to be
issued hereunder or the Commitments to issue or participate in Letters of Credit
hereunder, and the result shall be to increase the cost to the Agent or any Bank
of issuing, maintaining or participating in any Letter of Credit or its
Commitment to issue or participate in Letters of Credit hereunder or reduce any
amount receivable by the Agent or any Bank hereunder in respect of any Letter of
Credit (which increase in cost, or reduction in amount receivable, shall be the
result of the Agent's or such Bank's reasonable allocation of the aggregate of
such increases or reductions resulting from such event), then, upon demand by
the Agent or such Bank, the Borrower agrees to pay the Agent or such Bank, as
the case may be, from time to time as specified by the Agent or such Bank, as
the case may be, such additional amounts as shall be sufficient to compensate
the Agent or such Bank for such increased costs or reductions in amount. Each
Bank will furnish to the Borrower, within 180 days after such Bank actually
incurs such increase in cost or reduction in amount receivable, a certificate of
such Bank claiming compensation under this Section and setting forth the basis
and the additional amount or amounts to be paid to it hereunder.  Each such
certificate shall be conclusive, provided that the determination of such amount
or amounts is made on a reasonable basis.

     events or conditions, if any, have subjected or could in the reasonable
     opinion of the Required Banks subject the Borrower or any Guarantor to any
     tax, penalty, or other liability to a Plan, a Multiemployer Plan, the PBGC,
     or otherwise (or any combination thereof) which in the aggregate exceed or
     could reasonably be expected to exceed $25,000.

absolute discretion in an amount equal to the outstanding Letter of Credit
Liabilities as security for the Obligations, and the Agent may retain, as

Letters of Credit, any amounts received upon foreclosure, or in lieu of
foreclosure, through offset, as proceeds of any Collateral or otherwise.

     Section 12.4.  Performance by the Agent.  If the Borrower shall fail to
                    ------------------------
perform any covenant or agreement contained in any of the Loan Documents, the

the Borrower.  In such event, the Borrower agrees to, at the request of the
Agent, promptly pay any amount expended by the Agent in connection with such
performance or attempted performance to the Agent, together with interest
thereon at the Default Rate from and including the date of such expenditure to
but excluding the date such expenditure is paid in full.  Notwithstanding the
foregoing, it is expressly agreed that neither the Agent nor any Bank shall have
any liability or responsibility for the performance of any obligation of the
Borrower under this Agreement or any other Loan Document.

     Section 13.1.  Appointment, Powers and Immunities.  In order to
                    ----------------------------------
expedite the various transactions contemplated by this agreement, the Banks
hereby irrevocably appoint and authorize CBT and Chase to act as their Agent
hereunder and under each of the other Loan Documents.  CBT and Chase consent to

as are reasonably incidental thereto.  The Agent is hereby expressly authorized

     payments, prepayments, documents and other items received from the
     Borrower, the other Obligated Parties, and other Persons;

             (f)   To execute and deliver to the Borrower, the other Obligated
     Parties, and other Persons, all requests, demands, approvals, notices, and
     consents received from the Banks;

             (g)   To the extent permitted by the Loan Documents, to exercise on
     behalf of each Bank all rights and remedies of Banks upon the occurrence of
     any Event of Default;

             (h)   To accept, execute, and deliver the Borrower Security
     Agreement, the Guarantor Security Agreements, the Pledge Agreements, and
     any other security documents as the secured party; and

             (i)   To take such other actions as may be requested by Required
     Banks.

     Neither the Agent nor any of its Affiliates, officers, directors,
employees, attorneys, or agents shall be liable for any action taken or omitted
to be taken by any of them hereunder or otherwise in connection with this
Agreement or any of the other Loan Documents except for its or their own gross
negligence or willful misconduct. Without limiting the generality of the
preceding sentence, the Agent (i) 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; (ii) shall
have no duties or responsibilities except those expressly set forth in this
Agreement and the other Loan Documents, and shall not by reason of this
Agreement or any other Loan Document be a trustee or fiduciary for any Bank;
(iii) shall not be required to initiate any litigation or collection proceedings
hereunder or under any other Loan Document except to the extent requested by
Required Banks; (iv) shall not be responsible to the Banks for any recitals,
statements, representations or warranties contained in this Agreement or any
other Loan Document, or any certificate or other document referred to or
provided for in, or received by any of them under, this Agreement or any other
Loan Document, or for the value, validity, effectiveness, enforceability, or
sufficiency of this Agreement or any other Loan Document or any other document
referred to or provided for herein or therein or for any failure by any Person
to perform any of its obligations hereunder or thereunder; (v) 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; and (vi) shall incur no
liability under or in respect of any Loan Document by acting upon any notice,
consent, certificate, or other instrument or writing believed by it to be
genuine and signed or sent by the proper party or parties. As to any matters not
expressly provided for by this Agreement, the Agent shall in all cases be fully
protected in acting, or in refraining from acting, hereunder in accordance with
instructions signed by Required Banks, and such instructions of Required Banks
and any action taken or failure to act pursuant thereto shall be binding on all
of the Banks; 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 or any other Loan Document or applicable law.

     Section 13.2.  Rights of Agent as a Bank.  With respect to its
                    -------------------------
Commitment, the Advances made by it and the Note issued to it, each of Chase and
CBT shall have the same rights and powers hereunder as any Bank and may exercise
the same as though it were not acting as the Agent. At any time CBT or Chase is
a Bank hereunder, the term "Bank" or "Banks" shall, unless the context otherwise
indicates, include the Agent in its individual capacity. The Agent and its
Affiliates may (without having to account therefor to any Bank) accept deposits
from, lend money to, act as trustee under indentures of, provide merchant
banking services to, and generally engage in any kind of business with the
Borrower, any of its Subsidiaries, any other Obligated Party, and any other
Person who may do business with or own securities of the Borrower, any
Subsidiary, or any other Obligated Party, all as if it were not acting as the
Agent and without any duty to account therefor to the Banks.

     Section 13.3.  Sharing of Payments, Etc.    If any Bank shall obtain any
                    ------------------------
payment of any principal of or interest on any Advance made by it under this
Agreement or payment of any other obligation under the Loan Documents then owed
by the Borrower or any other Obligated Party to such Bank, whether voluntary,
involuntary, through the exercise of any right of setoff, banker's lien,
counterclaim or similar right, or otherwise, in excess of its pro rata share,
such Bank shall promptly purchase from the other Banks participations in the
Advances held by them hereunder in such amounts, and make such other adjustments
from time to time as shall be necessary to cause such purchasing Bank to share
the excess payment ratably with each of the other Banks in accordance with its
pro rata portion thereof.  To such end, all of the Banks shall make appropriate
adjustments among themselves (by the resale of participations sold or otherwise)
if all or any portion of such excess payment is thereafter rescinded or must
otherwise be restored.  The Borrower agrees, to the fullest extent it may
effectively do so under applicable law, that any Bank so purchasing a
participation in the Advances made by the other Banks may exercise all rights of
setoff, banker's lien, counterclaim, or similar rights with respect to such
participation as fully as if such Bank were a direct holder of Advances to the
Borrower in the amount of such participation.  Nothing contained herein shall
require any Bank to exercise any such right or shall affect the right of any
Bank to exercise, and retain the benefits of exercising, any such right with
respect to any other indebtedness or obligation of the Borrower.

     SECTION 13.4.  INDEMNIFICATION.  THE BANKS HEREBY AGREE TO INDEMNIFY
                    ---------------
THE AGENT FROM AND HOLD THE AGENT HARMLESS AGAINST (TO THE EXTENT NOT REIMBURSED
UNDER SECTIONS 14.1 AND 14.2, BUT WITHOUT LIMITING THE OBLIGATIONS OF THE
      -------------     ----
BORROWER UNDER SECTIONS 14.1 AND 14.2), RATABLY IN ACCORDANCE WITH THEIR
               -------------     ----
RESPECTIVE COMMITMENTS, ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, DEFICIENCIES, SUITS, COSTS, EXPENSES (INCLUDING
ATTORNEYS' FEES), AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY
BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST THE AGENT IN ANY WAY RELATING TO
OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY ACTION TAKEN OR OMITTED TO BE
TAKEN BY THE AGENT UNDER OR IN RESPECT OF ANY OF THE LOAN DOCUMENTS; PROVIDED,
FURTHER, THAT NO BANK SHALL BE LIABLE FOR ANY PORTION OF THE FOREGOING TO THE
EXTENT CAUSED BY THE AGENT'S GROSS NEGLIGENCE OR WILLFUL

                                      -77-
<PAGE>

MISCONDUCT. WITHOUT LIMITATION OF THE FOREGOING, IT IS THE EXPRESS INTENTION OF
THE BANKS THAT THE AGENT SHALL BE INDEMNIFIED HEREUNDER FROM AND HELD HARMLESS
AGAINST ALL OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, JUDGMENTS, DEFICIENCIES, SUITS, COSTS, EXPENSES (INCLUDING ATTORNEYS'
FEES), AND DISBURSEMENTS OF ANY KIND OR NATURE DIRECTLY OR INDIRECTLY ARISING
OUT OF OR RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF THE AGENT.
WITHOUT LIMITING ANY OTHER PROVISION OF THIS SECTION, EACH BANK AGREES TO
REIMBURSE THE AGENT PROMPTLY UPON DEMAND FOR ITS PRO RATA SHARE (CALCULATED ON
THE BASIS OF THE BANK'S RESPECTIVE COMMITMENTS) OF ANY AND ALL OUT-OF-POCKET
EXPENSES (INCLUDING ATTORNEYS' 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, THE LOAN
DOCUMENTS, TO THE EXTENT THAT THE AGENT IS NOT REIMBURSED FOR SUCH EXPENSES BY
THE BORROWER OR ANY OTHER OBLIGATED PARTY.

     Section 13.5.  Independent Credit Decisions.  Each Bank agrees that it
                    ----------------------------
has independently and without reliance on the Agent or any other Bank, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis of the Borrower and the Guarantors and decision to enter into
this Agreement and that it will, independently and without reliance upon the
Agent or any other Bank, and based upon such documents and information as it
shall deem appropriate at the time, continue to make its own analysis and
decisions in taking or not taking action under this Agreement or any of the
other Loan Documents. The Agent shall not be required to keep itself informed as
to the performance or observance by the Borrower or any Obligated Party of this
Agreement or any other Loan Document or to inspect the properties or books of
the Borrower or any Obligated Party. Except for notices, reports and other
documents and information expressly required to be furnished to the Banks by the
Agent hereunder or under the other Loan Documents, the Agent shall not have any
duty or responsibility to provide any Bank with any credit or other financial
information concerning the affairs, financial condition or business of the
Borrower or any Obligated Party (or any of their Affiliates) which may come into
the possession of the Agent or any of its Affiliates. Without in any way
limiting the foregoing, the Banks each acknowledge and agree that any and all
collateral audits (including the Semiannual Collateral Audits) conducted by the
Agent are for the Agent's benefit only. Although the results of such audits may
be provided to the Banks upon request, the Banks shall not be entitled to rely
on such audits, and the Agent shall have no liability to any of the Banks for
the accuracy, inaccuracy, completeness or incompleteness of such audits, any
information obtained as a result thereof or any conclusions drawn or decisions
made as a result thereof. Each Bank shall have the right to accompany the Agent
and participate in such audits as provided in Section 9.6.
                                              -----------

     Section 13.6.  Several Commitments.  The Commitments and other
                    -------------------
obligations of the Banks under this Agreement are several. The default by any
Bank in making an Advance in accordance with

                                      -78-
<PAGE>

its Commitment shall not relieve the other Banks of their obligations under this
Agreement. In the event of any default by any Bank in making any Advance, each
nondefaulting Bank shall be obligated to make its Advance but shall not be
obligated to advance the amount which the defaulting Bank was required to
advance hereunder. In no event shall any Bank be required to advance an amount
or amounts which shall in the aggregate exceed such Bank's Commitment. No Bank
shall be responsible for any act or omission of any other Bank.

     Section 13.7.  Successor Agent.  Subject to the appointment and
                    ---------------
acceptance of a successor Agent as provided below, the Agent may resign at any
time by giving notice thereof to the Banks and the Borrower, and the Agent may
be removed at any time with or without cause by Required Banks.  Upon any such
resignation or removal, Required Banks will have the right to appoint a
successor Agent.  If no successor Agent shall have been so appointed by Required
Banks and shall have accepted such appointment within 30 days after the retiring
Agent's giving of notice of resignation or the Required Banks' removal of the
retiring Agent, then the retiring Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be a commercial bank organized under the laws of
the United States of America or any State thereof and having combined capital
and surplus of at least $100,000,000.  Upon the acceptance of its appointment as
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all rights, powers, privileges, immunities, and duties of the
resigning or removed Agent, and the resigning or removed Agent shall be
discharged from its duties and obligations under this Agreement and the other
Loan Documents.  After any Agent's resignation or removal as Agent, the
provisions of this Article XIII shall continue in effect for its benefit in
                   ------------
respect of any actions taken or omitted to be taken by it while it was the
Agent.

expenses, and other charges incurred in connection with performing or obtaining

     Section 14.3.  Limitation of Liability. None of the Agent, any Bank, or any
                    -----------------------
Affiliate, officer, director, employee, attorney, or agent thereof shall have
any liability with respect to, and the Borrower hereby waives, releases, and
agrees not to sue any of them upon, any claim for any special, indirect,
incidental, or consequential damages suffered or incurred by the Borrower in
connection with, arising out of, or in any way related to, this Agreement or any
of the other Loan Documents, or any of the transactions contemplated by this
Agreement or any of the other Loan Documents. The Borrower hereby waives,
releases, and agrees not to sue the Agent or any Bank or any of their respective
Affiliates, officers, directors, employees, attorneys, or agents for punitive
damages in respect of any claim in connection with, arising out of, or in any
way related to, this Agreement or

any of the other Loan Documents, or any of the transactions contemplated by this
Agreement or any of the other Loan Documents.

     Section 14.4.  No Fiduciary Relationship. The relationship between the
                    -------------------------
Borrower and the Agent and between the Borrower and each Bank with respect to
the Loan Documents and the transactions governed thereby is solely that of
debtor and creditor, and neither the Agent nor any Bank has any fiduciary or
other special relationship with the Borrower with respect to the Loan Documents
and the transactions governed thereby, and no term or condition of any of the
Loan Documents shall be construed so as to deem the relationship between the
Borrower and the Agent or any Bank with respect to the Loan Documents and the
transactions governed thereby to be other than that of debtor and creditor.

     Section 14.5.  No Waiver; Cumulative Remedies. No failure on the part of
                    ------------------------------
the Agent or any Bank to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power, or privilege under this Agreement
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power, or privilege under this Agreement preclude any other or
further exercise thereof or the exercise of any other right, power, or
privilege. The rights and remedies provided for in this Agreement and the other
Loan Documents are cumulative and not exclusive of any rights and remedies
provided by law.

     Section 14.6.  Successors and Assigns.
                    ----------------------

          (a)  This Agreement shall be binding upon and inure to the benefit of
     the parties hereto and their respective successors and assigns. The
     Borrower shall not be permitted to assign or transfer any of its rights or
     obligations hereunder without the prior written consent of the Agent and
     all of the Banks. Any Bank may sell participations to one or more banks or
     other institutions in or to all or a portion of its rights and obligations
     under this Agreement and the other Loan Documents (including, without
     limitation, all or a portion of its Commitments, the Advances owing to it
     and its share of Letter of Credit Liabilities); provided, however, that (i)
     such Bank's obligations under this Agreement and the other Loan Documents
     (including, without limitation, its Commitment) shall remain unchanged,
     (ii) such Bank shall remain solely responsible to the Borrower for the
     performance of such obligations, (iii) such Bank shall remain the holder of
     its Note for all purposes of this Agreement, (iv) the Borrower shall
     continue to deal solely and directly with such Bank in connection with such
     Bank's rights and obligations under this Agreement and the other Loan
     Documents, and (v) such Bank shall not sell a participation that conveys to
     the participant the right to vote or give or withhold consents under this
     Agreement or any other Loan Document, other than the right to vote upon or
     consent to (A) any increase of such Bank's Commitment, (B) any reduction of
     the principal amount of, or interest to be paid on, the Advances of such
     Bank, (C) any reduction of any commitment fee or other amount payable to
     such Bank under any Loan Document, (D) any postponement of any date for the
     payment of any amount payable in respect of the Advances of such Bank, or
     (E) any material release of Collateral other than releases contemplated in
     the Loan Documents as in effect on the date hereof and releases upon full
     payment and performance of the Obligations and termination of the
     Commitments.

                                      -81-
<PAGE>

     Such participants shall have no rights under the Loan Documents, other than
     certain voting rights as provided above. Subject to the following, each
     Bank may obtain (on behalf of its participants) the benefits of Article V
                                                                     ---------
     with respect to all participations in its part of the Obligations
     outstanding from time to time. If a participant is entitled to the benefits
     of Article V or a Bank grants rights to its participants to vote or give or
        ---------
     withhold consents respecting the matters described above, then that Bank
     must include a voting mechanism in the relevant participation agreement
     whereby a majority of its portion of the Obligations (whether held by it or
     participated) shall control the vote for all of that Bank's portion of the
     Obligations. Except in the case of the sale of a participating interest to
     another Bank, the relevant participation agreement shall prohibit the
     participant from transferring, pledging, assigning, selling participations
     in, or otherwise encumbering its portion of the Obligations.

          (b)  The Borrower and each of the Banks agree that any Bank may at any
     time assign to one or more Eligible Assignees all, or a proportionate part
     of all, of its rights and obligations under this Agreement and the other
     Loan Documents (including, without limitation, its Commitment, Advances and
     Letter of Credit Liabilities); provided, however, that (i) the Borrower
     shall have given its prior written consent to such assignment, such consent
     not to be unreasonably withheld, provided that after the occurrence and
     during the continuance of a Default no consent of the Borrower shall be
     required for any such assignment, (ii) each such assignment shall be of a
     consistent, and not a varying, percentage of all of the assigning Bank's
     rights and obligations under this Agreement and the other Loan Documents,
     (iii) except in the case of an assignment of all of a Bank's rights and
     obligations under this Agreement and the other Loan Documents, the amount
     of the Commitment of the assigning Bank being assigned pursuant to each
     assignment (determined as of the date of the Assignment and Acceptance with
     respect to such assignment) shall in no event be less than $5,000,000, and
     the amount of the Commitment of the assigning Bank remaining after each
     such assignment shall in no event be less than $5,000,000, and (iv) the
     parties to each such assignment shall execute and deliver to the Agent for
     its acceptance and recording in the Register (as defined below), an
     Assignment and Acceptance, together with the Note subject to such
     assignment, and a processing and recordation fee of $3,000. 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 10 Business Days after the execution thereof, or, if
     so specified in such Assignment and Acceptance, the date of acceptance
     thereof by the Agent, (x) the assignee thereunder shall be a party hereto
     as a "Bank" 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 under the Loan Documents and
     (y) the Bank that is an assignor 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 the other Loan Documents (and, in the
     case of an Assignment and Acceptance covering all or the remaining portion
     of a Bank's rights and obligations under the Loan Documents, such Bank
     shall cease to be a party thereto).

                                      -82-
<PAGE>

          (c)  By executing and delivering an Assignment and Acceptance, the
     Bank that is an assignor 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 assigning
     Bank makes no representation or warranty and assumes no responsibility with
     respect to any statements, warranties, or representations made in or in
     connection with the Loan Documents or the execution, legality, validity,
     enforceability, genuineness, sufficiency, or value of the Loan Documents or
     any other instrument or document furnished pursuant thereto; (ii) such
     assigning Bank makes no representation or warranty and assumes no
     responsibility with respect to the financial condition of the Borrower or
     any Obligated Party or the performance or observance by the Borrower or any
     Obligated Party of its obligations under the Loan Documents; (iii) such
     assignee confirms that it has received a copy of the other Loan Documents,
     together with copies of the financial statements referred to in Section 8.2
                                                                     -----------
     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 or such assignor and based on such documents and information
     as it shall deem appropriate at the time, continue to make its own credit
     decisions in taking or not taking action under this Agreement and the other
     Loan Documents; (v) such assignee confirms that it is an Eligible Assignee;
     (vi) such assignee appoints and authorizes the Agent to take such action as
     agent on its behalf and exercise such powers under the Loan Documents as
     are delegated to the Agent by the terms thereof, together with such powers
     as are reasonably incidental thereto; and (vii) such assignee agrees that
     it will perform in accordance with their terms all of the obligations which
     by the terms of the Loan Documents are required to be performed by it as a
     Bank.

          (d)  The Administrative Agent may maintain at its Principal Office 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 Commitment 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, and the Banks may treat each Person whose name is
     recorded in the Register as a Bank hereunder for all purposes under the
     Loan Documents. 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.

          (e)  Upon its receipt of an Assignment and Acceptance executed by an
     assigning Bank and assignee representing that it is an Eligible Assignee,
     together with any Note subject to such assignment, the Agent shall, if such
     Assignment and Acceptance has been completed and is in substantially the
     form of Exhibit I hereto and all requirements set forth in this Section
             ---------
     have been satisfied, (i) accept such Assignment and Acceptance, (ii) record
     the information contained therein in the Register, if any, and (iii) give
     prompt written notice thereof to the Borrower. Within five Business Days
     after its receipt of such notice, the Borrower shall execute and deliver to
     the Agent in exchange for the surrendered Note a new Note payable to the
     order of such Eligible Assignee in an amount equal to the Commitment
     assumed by it

                                      -83-
<PAGE>

     pursuant to such Assignment and Acceptance and, if the assigning Bank has
     retained a Commitment, a new Note payable to the order of the assigning
     Bank in an amount equal to the Commitment retained by it hereunder (each
     such promissory note shall constitute a "Note" for purposes of the Loan
     Documents). Such new Notes shall be in an aggregate face amount of the
     surrendered Note, shall be dated the effective date of such Assignment and
     Acceptance, and shall otherwise be in substantially the form of Exhibit A-1
                                                                     -----------
     hereto.

          (f)  Any Bank may, in connection with any assignment or participation
     or proposed assignment or participation pursuant to this Section, disclose
     to the assignee or participant or proposed assignee or participant, subject
     to the confidentiality agreements between the Borrower and the Banks, any
     information relating to the Borrower, the Subsidiaries or the Foreign
     Affiliates furnished to such Bank by or on behalf of the Borrower, the
     Subsidiaries or the Foreign Affiliates.

          (g)  Any Bank may at any time, without the consent of the Borrower or
     the Agent, collaterally assign all or any of its rights under the Loan
     Documents to a Federal Reserve Bank; provided, however, that no such
     assignment shall release the assigning Bank from its obligations
     thereunder.

     Section 14.7.  Survival. All representations and warranties made in this
                    --------
Agreement or any other Loan Document or in any document, statement, or
certificate furnished in connection with this Agreement shall survive the
execution and delivery of this Agreement and the other Loan Documents, and no
investigation by the Agent or any Bank or any closing shall affect the
representations and warranties or the right of the Agent or any Bank to rely
upon them. Without prejudice to the survival of any other obligation of the
Borrower hereunder, the obligations of the Borrower under Sections 14.1 and 14.2
                                                          -------------     ----
shall survive repayment of the Notes and termination of the Commitments and the
Letters of Credit.

                    ----------------
LOAN DOCUMENTS REFERRED TO HEREIN REPRESENT THE FINAL AGREEMENT AMONG THE
PARTIES HERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES HERETO. THERE ARE

amendment, restatement and modification, but not in extinguishment, of the
Existing Agreement.

     Section 14.9.  Amendments, Etc. No amendment or waiver of any provision of
                    ---------------
this Agreement, the Notes, or any other Loan Document to which the Borrower is a
party (other than the Engagement Letter), nor any consent to any departure by
the Borrower therefrom, shall in any event be effective unless the same shall be
agreed or consented to in writing by Required Banks (or Agent with the consent
of Required Banks) and the Borrower, and each such waiver, amendment, or consent
shall be effective only in the specific instance and for the specific purpose
for which given; provided, that no amendment, waiver, or consent shall, unless
in writing and signed by all of the Banks and the Borrower, do any of the
following: (a) increase Commitments of the Banks or subject

                                      -84-
<PAGE>

the Banks to any additional obligations; (b) reduce the principal of, or
interest on, the Notes or any fees or other amounts payable hereunder (except
any fees payable to the Agent solely for its account as specified herein or in
the Engagement Letter); (c) postpone any date fixed for any payment of principal
of, or interest on, the Notes or any fees or other amounts payable hereunder
(except any fees payable to the Agent solely for its account as specified herein
or in the Engagement Letter); (d) increase any of the percentages of Eligible
Accounts and Eligible Inventory included in the Borrowing Base, as set forth in
the definition thereof, or any change in the definition of Eligible Accounts or
Eligible Inventory that results in an increase in the assets or values of assets
included in the Borrowing Base; (e) waive any of the conditions specified in
Article VII; (f) change the percentage of the Total Commitment Amount or of the
- -----------
aggregate unpaid principal amount of the Notes or the number of Banks which
shall be required for the Banks or any of them to take any action under this
Agreement; (g) change any provision contained in this Section 14.9; (h) release
                                                      ------------

any Collateral or any Guarantor, except for releases of Collateral in connection
with dispositions of assets expressly permitted by this Agreement and releases
of stock and Guaranties of Subsidiaries in connection with dissolutions,
liquidations or mergers expressly permitted by this Agreement or (i) extend the
Alternate Advance Rate Availability Period beyond July 31, 2000; provided,
further, that any election to terminate the Alternate Advance Rate Availability
Period earlier than July 31, 2000, as provided in the definition of "Alternate
Advance Rate Availability Period," shall be effective if approved by two or more
Banks. Notwithstanding anything to the contrary contained in this Section, no
amendment, waiver, or consent shall be made with respect to Article XIII hereof
                                                            ------------
without the prior written consent of the Agent.

     Section 14.10. Maximum Interest Rate. No provision of this Agreement or any
                    ---------------------
other Loan Document shall require the payment or the collection of interest in
excess of the maximum amount permitted by applicable law. If any excess of
interest in such respect is hereby provided for, or shall be adjudicated to be
so provided, in any Loan Document or otherwise in connection with this loan
transaction, the provisions of this Section shall govern and prevail and neither
the Borrower nor the sureties, guarantors, successors, or assigns of the
Borrower shall be obligated to pay the excess amount of such interest or any
other excess sum paid for the use, forbearance, or detention of sums loaned
pursuant hereto. In the event the Agent or any Bank ever receives, collects, or
applies as interest any such sum, such amount which would be in excess of the
maximum amount permitted by applicable law shall be applied as a payment and
reduction of the principal of the indebtedness; and, if the principal has been
paid in full, any remaining excess shall forthwith be paid to the Borrower. In
determining whether or not the interest paid or payable exceeds the Maximum
Rate, the Borrower, the Agent and each Bank shall, to the extent permitted by
applicable law, (a) characterize any non-principal payment as an expense, fee,
or premium rather than as interest, (b) exclude voluntary prepayments and the
effects thereof, and (c) amortize, prorate, allocate, and spread in equal or
unequal parts the total amount of interest throughout the entire contemplated
term of the indebtedness evidenced by the Notes so that interest for the entire
term does not exceed the Maximum Rate.

                    -------
in this Agreement and the other Loan Documents shall be given in writing and

this Agreement, all such communications shall be deemed to have been duly given
when transmitted by telecopy, subject to telephone confirmation of receipt, or
when personally delivered or, in the case of a mailed notice, when duly
deposited in the mails, in each case given or addressed as aforesaid; provided,
however, notices to the Agent pursuant to Article II and Article III shall not
                                          ----------     -----------
be effective until received by the Agent.

TEXAS AND THE APPLICABLE LAWS OF THE UNITED STATES OF AMERICA. THIS AGREEMENT
HAS BEEN ENTERED INTO IN DALLAS COUNTY, TEXAS, AND IT SHALL BE PERFORMABLE FOR

AGAINST THE BORROWER OR WITH RESPECT TO ANY OF ITS RESPECTIVE PROPERTY IN COURTS
IN OTHER JURISDICTIONS. ANY ACTION OR PROCEEDING BY THE BORROWER AGAINST THE
AGENT OR ANY BANK SHALL BE BROUGHT ONLY IN A COURT LOCATED IN DALLAS COUNTY,

     Section 14.13. Hedging Obligations.
                    -------------------

          (a)  The term "Debt," as defined and used in this Agreement, does not
     include Hedging Obligations of the Borrower or any Subsidiary or guaranties
     of Hedging Obligations of the Borrower or any Subsidiary. Accordingly, the
     Borrower and the Subsidiaries are permitted to incur Hedging Obligations to
     any Person; provided, however, that the Borrower will not, and will not
     permit any of its Subsidiaries to, incur any Hedging Obligations except
     pursuant to agreements or arrangements entered into in the ordinary course
     of business to hedge or mitigate risks to which the Borrower or any
     Subsidiary is exposed in the conduct of its business or the management of
     its liabilities.

          (b)  The term "Obligations," as defined and used in this Agreement,
     includes all Hedging Obligations of the Borrower or any Subsidiary to the
     Agent, CBT, Chase or any

                                      -86-
<PAGE>

     other Bank. Accordingly, all such Hedging Obligations are secured by the
     Collateral and guaranteed by the Guarantors pursuant to the Guaranties.

          (c)  The Borrower hereby irrevocably and unconditionally guarantees to
     each of the Agent, CBT, Chase, the other Banks and their respective
     affiliates and branches (each an "Obligee" and, collectively, the
                                       -------
     "Obligees"), the full and prompt payment and performance of any and all
      --------
     Hedging Obligations of each Subsidiary to each Obligee (all such Hedging
     Obligations being hereinafter referred to as the "Guaranteed Obligations").
                                                       ----------------------
     Such guaranty shall be an absolute, continuing, irrevocable, and
     unconditional guaranty of payment and performance, and not a guaranty of
     collection, and the Borrower shall remain liable on its obligations
     hereunder until the payment and performance in full of the Guaranteed
     Obligations. No set-off, counterclaim, recoupment, reduction, or diminution
     of any obligation, or any defense of any kind or nature which the Borrower
     or any Subsidiary may have against any Obligee or any other party shall be
     available to, or shall be asserted by, the Borrower against any Obligee or
     any subsequent holder of the Guaranteed Obligations or any part thereof or
     against payment of the Guaranteed Obligations or any part thereof.

          (d)  If the Borrower becomes liable for any obligations or
     indebtedness owing by any Subsidiary to any Obligee by endorsement or
     otherwise, other than under this Section, such liability shall not be in
     any manner impaired or affected hereby, and the rights of each Obligee
     shall be cumulative of any and all other rights that any Obligee may ever
     have against the Borrower.

          (e)  In the event of default by any Subsidiary in payment or
     performance of any of the Guaranteed Obligations, or any part thereof, when
     any part of the Guaranteed Obligations becomes due, whether by its terms,
     by acceleration, upon demand or otherwise, the Borrower shall promptly pay
     the amount due thereon to the applicable Obligee without notice or demand
     in Dollars and it shall not be necessary for any Obligee, in order to
     enforce such payment by the Borrower, first to institute suit or exhaust
     its remedies against any Subsidiary or others liable on such Guaranteed
     Obligations, or to enforce any rights against any collateral which shall
     ever have been given to secure such Guaranteed Obligations. Notwithstanding
     anything to the contrary contained in this Section, the Borrower hereby
     irrevocably subordinates to the prior and defeasible payment in full of the
     Guaranteed Obligations, any and all rights the Borrower may now or
     hereafter have under any agreement or at law or in equity (including,
     without limitation, any law subrogating the Borrower to the rights of any
     of the Obligees) to assert any claim against or seek contribution,
     indemnification or any other form of reimbursement from any Subsidiary or
     any other party liable for payment of any or all of the Guaranteed
     Obligations for any payment made by the Borrower under or in connection
     with this Section or otherwise.

          (f)  The Borrower hereby agrees that its obligations under this
     Section shall not be released, discharged, diminished, impaired, reduced,
     or affected for any reason or by the occurrence of any event, including,
     without limitation, one or more of the following events, whether or not
     with notice to or the consent of the Borrower: (i) the taking or accepting
     of

                                      -87-

     collateral as security for any or all of the Guaranteed Obligations or the
     release, surrender, exchange, or subordination of any collateral now or
     hereafter securing any or all of the Guaranteed Obligations; (ii) any
     partial release of the liability of the Borrower hereunder, or the full or
     partial release of any other guarantor from liability for any or all of the
     Guaranteed Obligations; (iii) any disability of the Borrower or any
     Subsidiary, or the dissolution, insolvency, or bankruptcy of the Borrower,
     any Subsidiary, any guarantor or any other party at any time liable for the
     payment of any or all of the Guaranteed Obligations; (iv) any renewal,
     extension, modification, waiver, amendment, or rearrangement of any or all
     of the Guaranteed Obligations or any instrument, document, or agreement
     evidencing, securing, or otherwise relating to any or all of the Guaranteed
     Obligations; (v) any adjustment, indulgence, forbearance, waiver, or
     compromise that may be granted or given by any Obligee to the Borrower, any
     Subsidiary or any other party ever liable for any or all of the Guaranteed
     Obligations; (vi) any neglect, delay, omission, failure, or refusal of any
     Obligee to take or prosecute any action for the collection of any of the
     Guaranteed Obligations or to foreclose or take or prosecute any action in
     connection with any instrument, document, or agreement evidencing,
     securing, or otherwise relating to any or all of the Guaranteed
     Obligations; (vii) the unenforceability or invalidity of any or all of the
     Guaranteed Obligations or of any instrument, document, or agreement
     evidencing, securing, or otherwise relating to any or all of the Guaranteed
     Obligations; (viii) any payment by any Subsidiary or any other party to any
     Obligee is held to constitute a preference under applicable bankruptcy or
     insolvency law or if for any other reason any Obligee is required to refund
     any payment or pay the amount thereof to someone else; (ix) the settlement
     or compromise of any of the Guaranteed Obligations; (x) the non-perfection
     of any security interest or lien securing any or all of the Guaranteed
     Obligations; (xi) any impairment of any collateral securing any or all of
     the Guaranteed Obligations; (xii) the failure of any Obligee to sell any
     collateral securing any or all of the Guaranteed Obligations in a
     commercially reasonable manner or as otherwise required by law; (xiii) any
     change in the corporate existence, structure, or ownership of the Borrower
     or any Subsidiary; or (xiv) any other circumstance which might otherwise
     constitute a defense available to, or discharge of, the Borrower or any
     Subsidiary.

          (g)  The Borrower hereby waives promptness, diligence, notice of any
     default under the Guaranteed Obligations, demand of payment, notice of
     acceptance of this guaranty, presentment, notice of protest, notice of
     dishonor, notice of the incurring by any Subsidiary of additional
     obligations or indebtedness, and all other notices and demands with respect
     to the Guaranteed Obligations and this guaranty.

$__________________                Dallas, Texas                  August 2, 1999


     FOR VALUE RECEIVED, the undersigned, CELLSTAR CORPORATION, a Delaware
corporation ("Maker"), hereby promises to pay to the order of _________________
              -----
("Payee"), at the offices of Chase Bank of Texas, National Association (formerly
  -----
known as Texas Commerce Bank National Association), as administrative agent
(together with any successor as provided in the Agreement, hereinbelow defined,
the "Administrative Agent"), at 1111 Fannin St., 9th Floor, MS46, Houston, Texas
     --------------------
77002, on the dates hereinafter specified, in lawful money of the United States
of America, the principal sum of _________________________ ($_____________) or
so much thereof as may be advanced and outstanding hereunder, together with
interest as hereinafter specified; provided however that Alternate Currency
Advances shall be payable to The Chase Manhattan Bank, as alternate currency
agent (together with any successor as provided in the Agreement, the "Alternate
                                                                      ---------
Currency Agent"), in accordance with the Credit Agreement.
- --------------

     This Note is one of the Revolving Credit Notes referred to in that certain
Amended and Restated Credit Agreement dated as of August 2, 1999, among Maker,
Payee, Administrative Agent, Alternate Currency Agent, The First National Bank
of Chicago, as syndication agent, National City Bank, as documentation agent,
and each of the other banks or lending institutions which is or may from time to
time become a signatory thereto and any successors or permitted assigns thereof
(as the same may be amended, modified, or supplemented from time to time, being
referred to herein as the "Agreement"). Capitalized terms used and not otherwise
                           ---------
defined in this Note have the respective meanings specified in the Agreement.

     The Agreement, among other things, contains provisions for acceleration of
the maturity of this Note upon the happening of certain stated events and also
for prepayments of Advances prior to the maturity of this Note upon the terms
and conditions specified in the Agreement.

     This Note evidences Advances made by the Agent and the Banks to Maker under
the Agreement. In addition, as provided in Section 3.4 of the Agreement, each
payment made by Agent pursuant to a drawing under a Letter of Credit shall
constitute and be deemed an Advance by the Banks to Maker, including an Advance
by Payee to Maker under this Note, in accordance with the terms of the
Agreement. Maker may borrow, repay and reborrow hereunder upon the terms and
conditions specified in the Agreement.

     The outstanding principal balance hereof shall bear interest at a varying
rate per annum which shall from day to day be equal to the lesser of (a) the
Maximum Rate, or (b) the Applicable Rate, each such change in the rate of
interest charged hereunder to become effective, without notice to Maker, on the
effective date of each change in the Applicable Rate or the Maximum Rate, as the
case may be; provided, however, if at any time the Applicable Rate shall exceed
             --------  -------
the Maximum Rate, thereby causing the interest rate hereon to be limited to the
Maximum Rate, then any subsequent

REVOLVING CREDIT NOTE - Page 1
<PAGE>

reduction in the Applicable Rate shall not reduce the rate of interest hereon
below the Maximum Rate until the total amount of interest accrued hereon equals
the amount of interest which would have accrued hereon if the Applicable Rate
had at all times been in effect.

     Accrued and unpaid interest on this Note shall be due and payable on the
dates specified in Section 2.5 of the Agreement.  All principal of this Note
                   -----------
shall be due and payable on the Termination Date. All past due principal and
interest shall bear interest at the Default Rate. Interest payable at the
Default Rate shall be payable from time to time on demand.

     Interest on the Eurodollar Advances and Alternate Currency Advances shall
be computed on the basis of a year of 360 days and the actual number of days
elapsed; provided that, in the case of Advances denominated in any Alternate
Currency in respect of which the Agent has determined that a 365-day basis is
standard market practice in the applicable interbank market, interest shall be
calculated on the basis of a year of 365 days and the actual number of days
elapsed. Interest on the Floating Rate Advances shall be computed on the basis
of a year of 360 days and the actual number of days elapsed at all times when
the Alternate Base Rate is based on the Federal Funds Effective Rate and a year
of 365 or 366 days, as the case may be, and the actual number of days elapsed at
all times when the Alternate Base Rate is the Prime Rate.

     Notwithstanding anything to the contrary contained herein, no provisions of
this Note shall require the payment or permit the collection of interest in
excess of the Maximum Rate. If any excess of interest in such respect is herein
provided for, or shall be adjudicated to be so provided, in this Note or
otherwise in connection with this loan transaction, the provisions of this
paragraph shall govern and prevail, and neither Maker nor the sureties,
guarantors, successors or assigns of Maker shall be obligated to pay the excess
amount of such interest, or any other excess sum paid for the use, forbearance
or detention of sums loaned pursuant hereto. If for any reason interest in
excess of the Maximum Rate shall be deemed charged, required or permitted by any
court of competent jurisdiction, any such excess shall be applied as a payment
and reduction of the principal of indebtedness evidenced by this Note; and, if
the principal amount hereof has been paid in full, any remaining excess shall
forthwith be paid to Maker. In determining whether or not the interest paid or
payable exceeds the Maximum Rate, Maker and Payee shall, to the extent permitted
by applicable law, (i) characterize any non-principal payment as an expense,
fee, or premium rather than as interest, (ii) exclude voluntary prepayments and
the effects thereof, and (iii) amortize, prorate, allocate, and spread in equal
or unequal parts the total amount of interest throughout the entire contemplated
term of the indebtedness evidenced by this Note so that the interest for the
entire term does not exceed the Maximum Rate.

     THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF TEXAS AND THE APPLICABLE LAWS OF THE UNITED STATES OF AMERICA. THIS
NOTE IS PERFORMABLE IN DALLAS COUNTY, TEXAS.

     Maker and each surety, guarantor, endorser, and other party ever liable for
payment of any sums of money payable on this Note jointly and severally waive
notice, presentment, demand for payment, protest, notice of protest and non-
payment or dishonor, notice of acceleration, notice of

grace, and all other formalities of any kind, except any notice and grace
periods provided in the Agreement, and consent to all extensions without notice
for any period or periods of time and partial payments, before or after
maturity, and any impairment of any Collateral securing this Note, all without
prejudice to the holder. The holder shall similarly have the right to deal in
any way, at any time, with one or more of the foregoing parties without notice
to any other party, and to grant any such party any extensions of time for
payment of any of said indebtedness, or to release or substitute part or all of
the Collateral securing this Note, or to grant any other indulgences or
forbearances whatsoever, without notice to any other party and without in any
way affecting the personal liability of any party hereunder.

     Maker hereby authorizes the holder hereof to endorse on the Schedule
attached to this Note or any continuation thereof or to record in its internal
records all advances made to Maker hereunder and all payments made on account of
the principal thereof, which endorsements or records shall be prima facie
evidence as to the outstanding principal amount of this Note; provided, however,
any failure by the holder hereof to make any endorsement or record shall not
limit or otherwise affect the obligations of Maker under the Agreement or this
Note.

     This Note is given in amendment, restatement and modification (but not in
extinguishment or novation) of the indebtedness evidenced by that certain
Revolving Credit Note dated October 15, 1997 in the original principal amount of
$_________, executed by Maker and payable to the order of Payee.

and not otherwise defined herein shall have their respective meanings as

                                  ARTICLE II

                               Security Interest
                               -----------------

     Section 2.1  Security Interest.  As collateral security for the prompt
                  -----------------
payment and performance in full when due of the Obligations (whether at stated
maturity, by acceleration, or otherwise), the Debtor hereby grants to the Agent,
for the pro rata benefit of the Banks, a first priority lien on and security
interest in all of the Debtor's right, title, and interest in and to the
following, whether now owned or hereafter arising or acquired and wherever
located (collectively, the "Collateral"):
                            ----------

BORROWER SECURITY AGREEMENT - Page 4
<PAGE>

               (h)  all Proceeds and products of any or all of the foregoing.

Without limiting the foregoing, this Agreement secures the payment of all
amounts that constitute part of the Obligations and would be owed by the Debtor
to the Agent, any Co-Agent or any Bank but for the fact that they are
unenforceable or not allowable due to the existence of bankruptcy,
reorganization, or similar proceedings involving the Debtor.  If the grant,
pledge, or collateral transfer or assignment of any rights of the Debtor under
any contract included in the Collateral is expressly prohibited by such
contract, then the security interest hereby granted therein nonetheless remains
effective to the extent allowed by UCC Section 9.318 or other applicable law but
is otherwise limited by that prohibition.

     Section 2.2  Debtor Remains Liable.  Notwithstanding anything to the
                  ---------------------
contrary contained herein, (a) the Debtor shall remain liable under the
contracts and agreements included in the Collateral to the extent set forth
therein to perform all of its duties and obligations thereunder to the same
extent as if this Agreement had not been executed, (b) the exercise by the Agent
of any of its rights hereunder shall not release the Debtor from any of its
duties or obligations under the contracts and agreements included in the
Collateral, and (c) neither the Agent nor any Bank shall have any obligation or
liability under any of the contracts and agreements included in the Collateral
by reason of this Agreement, nor shall the Agent or any Bank be obligated to
perform any of the obligations or duties of the Debtor thereunder or to take any
action to collect or enforce any claim for payment assigned hereunder.

                                  ARTICLE III

                        Representations and Warranties
                        ------------------------------

     To induce the Agent to enter into this Agreement and the Agent, the Co-
Agents and the Banks to enter into the Credit Agreement, the Debtor represents
and warrants to the Agent that:

     Section 3.1  Title.  The Debtor is, and with respect to Collateral
                  -----
acquired after the date hereof the Debtor will be, the legal and beneficial
owner of the Collateral free and clear of any Lien, except Permitted Liens.

     Section 3.2  Accounts.  Unless the Debtor has given the Agent written
                  --------
notice to the contrary, whenever the security interest granted hereunder
attaches to an Account, the Debtor shall be deemed to have represented and
warranted to the Agent as to each and all of its Accounts that (a) each Account
is genuine and in all respects what it purports to be, (b) each Account
represents the legal, valid, and binding obligation of the account debtor
evidencing indebtedness unpaid and owed by such account debtor arising out of
the performance of labor or services by the Debtor or the sale or lease of goods
by the Debtor, (c) the amount of each Account represented as owing is the
correct amount actually and unconditionally owing except for normal trade
discounts granted in the ordinary course of business, and (d) to the best of
Debtor's knowledge, no Account is subject to any offset, counterclaim, or other
defense.

     Section 3.3  Financing Statements.  No financing statement, security
                  --------------------
agreement, or other Lien instrument covering all or any part of the Collateral
is on file in any public office, except those filed in favor of the Agent
pursuant to this Agreement or with respect to any other Permitted Liens.  Except
as set forth on Schedule 3 hereto, the Debtor has not within the past five years
                ----------
done business under any name or trade name other than its legal name set forth
at the beginning of this Agreement.

     Section 3.4  Principal Place of Business. The principal place of business
                  ---------------------------
and chief executive office of the Debtor, and the office where the Debtor keeps
its books and records, is located at the address of the Debtor shown at the
beginning of this Agreement.

     Section 3.5  Location of Collateral.  All Inventory and Equipment of the
                  ----------------------
Debtor is located at the places specified on Schedule 1 hereto.  The Debtor has
                                             ----------
exclusive possession and control of its Inventory and Equipment.  None of the
Inventory or Equipment is evidenced by a Document (including, without
limitation, a negotiable document of title).  All Instruments and Chattel Paper
have been delivered to the Agent.

     Section 3.6  Perfection.  This Agreement creates a security interest in
                  ----------
the Collateral in favor of the Agent.  Upon the filing of UCC financing
statements in favor of the Agent in the jurisdictions listed on Schedule 2
                                                                ----------
attached hereto, and upon the Agent's obtaining possession of all Documents and
Instruments of the Debtor, the security interest in favor of the Agent created
herein is and will constitute a valid and perfected Lien upon and security
interest in the Collateral, subject to no equal or prior Lien, except the
Permitted Liens.


                                  ARTICLE IV

                                   Covenants
                                   ---------

     The Debtor covenants and agrees with the Agent that until the Obligations
are paid and performed in full and all Commitments have terminated:

     Section 4.1  Encumbrances.  The Debtor shall not create, permit, or suffer
                  ------------
to exist, and shall defend the Collateral against, any Lien on the Collateral,
except the Permitted Liens, and shall defend the Debtor's rights in the
Collateral and the Agent's security interest in the Collateral against the
claims and demands of all Persons.  The Debtor shall do nothing to impair the
rights of the Agent in the Collateral.

     Section 4.2  Modification of Accounts.  The Debtor shall, in accordance
                  ------------------------
with prudent business practices, endeavor to collect or cause to be collected
from each account debtor under its Accounts, as and when due, any and all
amounts owing under such Accounts.  Without the prior written consent of the
Agent, the Debtor shall not (a) grant any extension of time for any payment with
respect to any of the Accounts, except for extensions of time granted in the
ordinary course of Debtor's business for payment with respect to Accounts not
included in the Borrowing Base,

                   ---------------------------------
if any warehouse receipt or receipt in the nature of a warehouse receipt is

                   ----------------------

the Accounts.  In connection with such collections, the Debtor may take (and, at
the Agent's direction, shall take) such actions as the Debtor or the Agent may
deem necessary or advisable to enforce collection of the Accounts.  At any time,
if an Event of Default shall have occurred and be continuing, the Agent shall
have the right to, or upon the request of the Agent the Debtor shall, instruct
all account debtors and other Persons obligated in respect of the Accounts to
make all payments on the Accounts either (a) directly to the Agent, for the pro
rata benefit of the Banks (by instructing that such payments be remitted to a

or (b) to one or more other banks in the United States of America (by
instructing that such payments be remitted to a post office box which shall be
in the name or under the control of the Agent) under arrangements in form and
substance satisfactory to the Agent pursuant to which the Debtor shall have
irrevocably instructed such other bank (and such other bank shall have agreed)
to remit all such payments directly to the Agent.  In addition to the foregoing,
the Debtor agrees that if any Proceeds of any Collateral

(including payments made in respect of Accounts) shall be received by the Debtor
while an Event of Default exists, the Debtor shall promptly deliver such
Proceeds to the Agent, for the pro rata benefit of the Banks, with any necessary
endorsements. Until such Proceeds are delivered to the Agent, such Proceeds
shall be held in trust by the Debtor for the benefit of the Agent and shall not
be commingled with any other funds or property of the Debtor. All Proceeds of
Collateral received by the Agent pursuant to this Section may at the option of
the Required Banks in the exercise of their absolute discretion, (i) be applied
by the Agent, the Co-Agents and the Banks to their respective Obligations in
such order and manner as they may each elect in their absolute discretion, or
(ii) be deposited to the credit of Debtor and held as collateral for the
Obligations or permitted to be used by Debtor in the ordinary course of its
business.

     directly to the Agent or as the Agent shall direct; (B) after the
     occurrence and during the continuance of an Event of Default, to receive
     payment of and receipt for any and all monies, claims, and other amounts
     due and to become due at any time in respect of or arising out of any

     completely as though the Agent were the absolute owner thereof for all
     purposes, and to do, at the Agent's option and the Debtor's expense, at any
     time, or from time to time, all acts and things which the Agent deems

     This power of attorney is a power coupled with an interest and shall be
irrevocable.  The Agent shall be under no duty to exercise or withhold the
exercise of any of the rights, powers, privileges, and options expressly or

is conferred on the Agent solely to protect, preserve, and realize upon its
security interest in the Collateral.  The Agent will exercise its best efforts
to notify Debtor of any action taken by the Agent in its capacity as attorney-
in-fact pursuant to this Section, promptly after such action is taken, provided

upon the Agent or affect its rights and remedies hereunder, at law or in equity.

     Section 5.2    Setoff; Property Held by the Agents and the Banks.  If an
                    -------------------------------------------------
Event of Default shall have occurred and be continuing, the Agent, each Co-Agent
and each Bank shall have the right to set off and apply against the Obligations,
at any time and without notice to the Debtor, any and all deposits (general or
special, time or demand, provisional or final) or other sums at any time
credited by or owing from the Agent, any Co-Agent or any Bank to the Debtor
whether or not the Obligations are then due.  As additional security for the
Obligations, the Debtor hereby grants the Agent, each Co-Agent and each Bank a
security interest in all money, instruments, and other property of the Debtor
now or hereafter held by the Agent, any Co-Agent or any Bank, including without
limitation, property held in safekeeping.  In addition to the Agent's, any Co-
Agent's or any Bank's right of setoff and as further security for the
Obligations, the Debtor hereby grants the Agent, each Co-Agent and each Bank a
security interest in all deposits (general or special, time or demand,
provisional or final) of the Debtor now or hereafter on deposit with or held by
the Agent, any Co-Agent or any Bank and all other sums at any time credited by
or owing from the Agent, any Co-Agent or any Bank to the Debtor.  The rights and
remedies of the Agent, each Co-Agent and each Bank hereunder are in addition to
other rights and remedies (including, without limitation, other rights of
setoff) which the Agent, any Co-Agent or any Bank may have.

                    ------------------------
perform any covenant or agreement contained in this Agreement, the Agent may
perform or attempt to perform such covenant or agreement on behalf of the
Debtor. In such event, the Debtor shall, at the request of the Agent, promptly
pay any amount expended by the Agent in connection with such performance or
attempted performance to the Agent, together with interest thereon at the
Default Rate from and including the date of such expenditure to but excluding
the date such expenditure is paid in full. Notwithstanding the foregoing, it is
expressly agreed that the Agent shall not have any liability or responsibility
for the performance of any obligation of the Debtor under this Agreement.

     Section 5.4    Subrogation.  If any of the Obligations are given in renewal
                    -----------
or extension or applied toward the payment of indebtedness secured by any Lien,
the Agent, the Co-Agents and the Banks shall be, and are hereby, subrogated to
all of the rights, titles, interests and Liens securing the indebtedness so
renewed, extended, or paid.

     Section 5.5    Agent's Duty of Care.  Other than the exercise of reasonable
                    --------------------
care and the physical custody of the Collateral while held by the Agent
hereunder, the Agent shall have no responsibility for or obligation or duty with
respect to all or any part of the Collateral or any matter or proceeding arising
out of or relating thereto, including without limitation any obligation or duty
to collect any sums due in respect thereof or to protect or preserve any rights
against prior parties or any other rights pertaining thereto, it being
understood and agreed that Debtor shall be responsible for preservation of all
rights in the Collateral. Without limiting the generality of the foregoing, the
Agent shall be conclusively deemed to have exercised reasonable care in the
custody of the Collateral if the Agent takes such action, for purposes of
preserving rights in the Collateral, as Debtor may reasonably request in
writing, but no failure or omission or delay by the Agent in complying with any
such request by Debtor, and no refusal by the Agent to comply with any such
request by Debtor, shall be deemed to be a failure to exercise reasonable care.

     Section 6.1    Rights and Remedies.  If an Event of Default shall have
                    -------------------
occurred and be continuing, the Agent shall have the following rights and
remedies:

          (i)       In addition to all other rights and remedies granted to the
     Agent in this Agreement or in any other Loan Document or by applicable law,
     the Agent shall have all of the rights and remedies of a secured party
     under the UCC (whether or not the UCC applies to the affected Collateral).
     Without limiting the generality of the foregoing, the Agent may (1) without
     demand or notice to the Debtor, collect, receive, or take possession of the
     Collateral or any part thereof and for that purpose the Agent may enter
     upon any premises on which the Collateral is located and remove the
     Collateral therefrom or render it inoperable, and/or (2) sell, lease, or
     otherwise dispose of the Collateral, or any part thereof, in one or more
     parcels at public or private sale or sales, at the Agent's offices or
     elsewhere, for cash, on credit or for future delivery, and upon such other
     terms as the Agent may deem commercially reasonable. The Agent shall have
     the right at any public sale or sales, and, to the extent permitted by
     applicable law, at any private sale or sales, to bid and become a purchaser
     of the Collateral or any part thereof free of any right or equity of
     redemption on the part of the Debtor, which right or equity of redemption
     is hereby expressly waived and released by the Debtor. Upon the request of
     the Agent, the Debtor shall assemble the Collateral and make it available
     to the Agent at any place designated by the Agent that is reasonably
     convenient to the Debtor and the Agent. The Debtor agrees that the Agent
     shall not be obligated to give more than five days written notice of the
     time and place of any public sale or of the time after which any private
     sale may take place and that such notice shall constitute reasonable notice
     of such matters. The Agent shall not be obligated to make any sale of
     Collateral if it shall determine not to do so, regardless of the fact that
     notice of sale of Collateral may have been given. The Agent may, without
     notice or publication, adjourn any public or private sale or cause the same
     to be adjourned from time to time by announcement at the time and place
     fixed for sale, and such sale may, without further notice, be made at the
     time and place to which the same was so adjourned. The Debtor shall be
     liable for all expenses of retaking, holding, preparing for sale, or the
     like, and all reasonable attorneys' fees, legal expenses, and all other
     costs and expenses incurred by the Agent, any Co-Agent or any Bank in
     connection with the collection of the Obligations and the enforcement of
     the Agent's rights under this Agreement. The Debtor shall remain liable for
     any deficiency if the Proceeds of any sale or other disposition of the
     Collateral are insufficient to pay the Obligations in full. The Agent, the
     Co-Agents and the Banks may apply the Collateral against the Obligations in
     such order and manner as they may elect in their absolute discretion. The
     Debtor waives all rights of marshalling, valuation, and appraisal in
     respect of the Collateral.

          (ii)      The Agent may cause any or all of the Collateral held by it
     to be transferred into the name of the Agent or the name or names of the
     Agent's nominee or nominees.

          (iii)     The Agent may collect or receive all money or property at
     any time payable or receivable on account of or in exchange for any of the
     Collateral, but shall be under no obligation to do so.

          (iv)      On any sale of the Collateral, the Agent is hereby
     authorized to comply with any limitation or restriction with which
     compliance is necessary, in the view of the Agent's counsel, in order to
     avoid any violation of applicable law or in order to obtain any required
     approval of the purchaser or purchasers by any applicable Governmental
     Authority.

                               -----------------

     Section 2.1.  Security Interest.  As collateral security for the prompt
                   -----------------
payment and performance in full when due of the Obligations (whether at stated
maturity, by acceleration, or otherwise), each Debtor hereby grants to the
Agent, for the pro rata benefit of the Banks, a first priority lien on and
security interest in all of its personal property, including without limitation
all of its right, title, and interest in and to the following, whether now owned

pledge, or collateral transfer or assignment of any rights of any Debtor under
any contract included in the Collateral is expressly prohibited by such
contract, then the security interest hereby granted nonetheless remains

                   ---------------------
contrary contained herein, (a) each Debtor shall remain liable under the
contracts and agreements included in the Collateral to the extent set forth
therein to perform all of its duties and obligations thereunder to the same
extent as if this Agreement had not been executed, (b) the exercise by the Agent
of any of its rights hereunder shall not release any Debtor from any of its
duties or obligations under the contracts and agreements included in the
Collateral, and (c) neither the Agent, the Syndication Agent, the Documentation
Agent, the Alternate Currency Agent nor any Bank shall have any obligation or
liability under any of the contracts and agreements included in the Collateral
by reason of this Agreement, nor shall the Agent, the Syndication Agent, the
Documentation Agent, the Alternate Currency Agent or any Bank be obligated to
perform any of the obligations or duties of any Debtor thereunder or to take any
action to collect or enforce any claim for payment assigned hereunder.

                                  ARTICLE III

                        Representations and Warranties
                        ------------------------------

     Each Debtor represents and warrants to the Agent that:

     Section 3.1.  Title. The Debtors are, and with respect to Collateral
                   -----
acquired after the date hereof the Debtors will be, the legal and beneficial
owners of their respective Collateral free and clear of any Lien, except
Permitted Liens.

     Section 3.2.  Accounts. Unless a Debtor has given the Agent written notice
                   --------
to the contrary, whenever the security interest granted hereunder attaches to an
Account, each Debtor shall be

GUARANTOR SECURITY AGREEMENT - Page 5

Accounts that (a) each Account is genuine and in all respects what it purports
to be, (b) each Account represents the legal, valid, and binding obligation of
the account debtor evidencing indebtedness unpaid and owed by such account
debtor arising out of the performance of labor or services by such Debtor or the
sale or lease of goods by such Debtor, (c) the amount of each Account
represented as owing is the correct amount actually and unconditionally owing
except for normal trade discounts granted in the ordinary course of business,
and (d) to the best of Debtor's knowledge, no Account is subject to any offset,
counterclaim, or other defense.

     Section 3.3.  Financing Statements. No financing statement, security
                   --------------------
agreement, or other Lien instrument covering all or any part of the Collateral
is on file in any public office, except those filed in favor of the Agent
pursuant to this Agreement or with respect to any other Permitted Liens. Except
as set forth on Schedule 3 hereto, no Debtor has within the past five years done
                ----------
business under any name or trade name other than its legal name set forth at the
beginning of this Agreement.

     Section 3.4.  Principal Place of Business. The principal place of business
                   ---------------------------

exclusive possession and control of its Inventory and Equipment. None of the
Inventory or Equipment of any Debtor is evidenced by a Document (including,

     Section 3.6.  Perfection. This Agreement creates a security interest in the
                   ----------
Collateral in favor of the Agent. Upon the filing of UCC financing statements in
favor of the Agent in the jurisdictions listed on Schedule 2 attached hereto,
                                                  ----------
and upon the Agent's obtaining possession of all Documents and Instruments of

constitute a valid and perfected Lien upon and security interest in the
Collateral, subject to no equal or prior Lien, except the Permitted Liens.

     Section 3.7.  Benefit to Debtors. The value of the consideration received
                   ------------------
and to be received by each Debtor as a result of the Borrower, the Agent, the
Syndication Agent, the Documentation Agent, the Alternate Currency Agent and the
Banks entering into and obtaining credit under the Credit Agreement and the
Debtors executing and delivering this Agreement is reasonably worth at least as
much as the liability and obligation of such Debtor hereunder, and such
liability and obligation and the Borrower's entering into and obtaining credit
under the Credit Agreement have benefitted and may reasonably be expected to
benefit each Debtor directly and indirectly.

     Section 3.8.  Credit Agreement. Each and every representation and warranty
                   ----------------
contained in the Credit Agreement is true and correct in all respects.

                   ------------
exist, and each Debtor shall defend the Collateral against, any Lien on the
Collateral, except the Permitted Liens, and each Debtor shall defend its rights
in the Collateral and the Agent's security interest in the Collateral against
the claims and demands of all Persons. No Debtor shall do anything to impair the
rights of the Agent in the Collateral.

     Section 4.2.  Modification of Accounts. Each Debtor shall, in accordance
                   ------------------------
with prudent business practices, endeavor to collect or cause to be collected
from each account debtor under its Accounts, as and when due, any and all
amounts owing under such Accounts. Without the prior written consent of the

respect to any of the Accounts, except for extensions of time granted in the
ordinary course of such Debtor's business for payment with respect to Accounts
not included in the Borrowing Base, (b) compromise, compound, or settle any of
the Accounts for less than the full amount thereof, except for compromise,

     Section 4.4.  Further Assurances. At any time and from time to time, upon
                    ------------------

carry out the provisions and purposes of this Agreement. Without limiting the
generality of the foregoing, each Debtor shall (a) execute and deliver to the

other reproduction of this Agreement or of any financing statement covering the
Collateral or any part thereof shall be sufficient as a financing statement and
may be filed as a financing statement.

                   -----------------------

expense, maintain or cause to be maintained insurance with respect to the
Collateral in such amounts, against such risks, in such form, and with such
insurers as shall be satisfactory to the Agent from time to time. Each policy
for liability insurance shall provide for all losses to be paid on behalf of the
Agent, for the pro rata benefit of the Banks and the Debtor as their interests
may appear. Each policy for property insurance shall contain loss payable
clauses and a loss payable endorsement in favor of the Agent, for the pro rata
benefit of the Banks, as its interest may appear. If the Debtors shall fail to
maintain or cause to be maintained the insurance required by this Agreement, the
Agent shall have the right (but shall be under no obligation) to obtain such
insurance and the Debtors jointly and severally agree to reimburse the Agent for
all costs and expenses incurred by the Agent in obtaining such insurance. All
such insurance shall provide that no cancellation, reduction in amount, or
change in coverage thereof shall be effective unless the Agent has received 30
days prior written notice thereof. The Debtors shall deliver to the Agent, the
Syndication Agent, the Documentation Agent, the Alternate Currency Agent and
each Bank copies of all insurance policies required by this Agreement.

     Section 4.6.  Inspection Rights. Each Debtor shall permit the Agent, each

time contact account debtors and other obligors to verify the existence,
amounts, and terms of any Debtor's Accounts.

     Section 4.7.  Mortgagee's and Landlord's Agreements. With respect to each
                   -------------------------------------
location of Inventory having an aggregate value of $100,000 or more, as

             ----------
property owned by such Debtor and each landlord of real property leased by such
Debtor who has not previously done so to execute and deliver to the Agent, on or
before the date hereof, instruments satisfactory in form and substance to the
Agent by which such mortgagee or landlord waives its rights, if any, in the
Collateral (each, a "Landlord's Agreement"). After the date hereof, each Debtor
                     --------------------
shall promptly deliver or cause to be delivered to the Agent Landlord's
Agreements in accordance with this Section for each location where the Inventory
hereafter has an aggregate value of $100,000 or more. At the request of the
Agent, each Debtor shall promptly deliver or cause to be delivered Landlord's

     Section 4.8.  Corporate Changes. No Debtor shall change its name, identity,
                   -----------------
or corporate structure in any manner that might make any financing statement
filed in connection with this Agreement seriously misleading unless such Debtor
shall have given the Agent 30 days prior written notice thereof and shall have
taken all action deemed necessary or desirable by the Agent to make each
financing statement not seriously misleading. No Debtor shall change its
principal place of business, chief executive office, or the place where it keeps
its books and records unless it shall have given the Agent 30 days prior written
notice thereof and shall have taken all action deemed necessary or desirable by
the Agent to cause its security interest in the Collateral to be perfected with
the priority required by this Agreement.

     Section 4.9.  Books and Records; Information. The Debtors shall keep

time to time at the request of the Agent deliver to the Agent such information
regarding the Collateral and such Debtor as the Agent may request, including,

identity and existence of the Collateral. Each Debtor shall mark its books and
records to reflect the security interest of the Agent under this Agreement.

     Section 4.10. Equipment and Inventory.
                   -----------------------

          (a) The Debtors shall keep the Equipment and Inventory at the
     locations specified on Schedule 1 hereto or, upon 30 days prior written
                            ----------
     notice to the Agent, at such other places within the United States of
     America where all action required to perfect the Agent's security interest
     in the Equipment and Inventory with the priority required by this Agreement
     shall have been taken.

          (b) The Debtors shall maintain the Equipment and Inventory in good
     condition and repair (ordinary wear and tear excepted). None of the Debtors
     shall permit any waste or destruction of the Equipment or Inventory or any
     part thereof. None of the Debtors shall permit the Equipment or Inventory
     to be used in violation of any law, rule, or regulation or inconsistently
     with the terms of any policy of insurance. None of the Debtors shall use or
     permit any of the Equipment or Inventory to be used in any manner or for
     any purpose that would impair its value or expose it to unusual risk.

     Section 4.11. Warehouse Receipts Non-Negotiable. Each Debtor agrees that
                   ---------------------------------
if any warehouse receipt or receipt in the nature of a warehouse receipt is
issued in respect of any of the Collateral, such warehouse receipt or receipt in
the nature thereof shall not be "negotiable" (as such term is used in Section
7.104 of the UCC as in effect in any relevant jurisdiction or under relevant
law).

     Section 4.12. Notification. The Debtors shall promptly, and in any event
                   ------------
within five days after any Debtor obtains knowledge or becomes aware of any of

been made or asserted against any of the Collateral, (b)

GUARANTOR SECURITY AGREEMENT - Page 9
<PAGE>

any material damage to or loss of any of the Collateral, (c) the occurrence of
any other event that could have a material adverse effect on the Collateral or
the security interest created hereunder, and (d) the occurrence or existence of
any Default.

     Section 4.13.  Collection of Accounts.  Except as otherwise provided in
                    ----------------------
this Section, the Debtors shall have the right to collect and receive payments
on the Accounts.  In connection with such collections, the Debtors may take
(and, at the Agent's direction, shall take) such actions as the Debtors or the
Agent may deem necessary or advisable to enforce collection of the Accounts.  At
any time, if an Event of Default shall have occurred and be continuing, the
Agent shall have the right to, or upon the request of the Agent the Debtors
shall, instruct all account debtors and other Persons obligated in respect of
the Accounts to make all payments on the Accounts either (a) directly to the
Agent (by instructing that such payments be remitted to a post office box which
shall be in the name and under the control of the Agent), or (b) to one or more
other banks in the United States of America (by instructing that such payments
be remitted to a post office box which shall be in the name or under the control
of the Agent) under arrangements in form and substance satisfactory to the Agent
pursuant to which the Debtors shall have irrevocably instructed such other bank
(and such other bank shall have agreed) to remit all such payments directly to
the Agent.  In addition to the foregoing, each Debtor agrees that if any
Proceeds of any Collateral (including payments made in respect of Accounts)
shall be received by such Debtor while an Event of Default exists, such Debtor
shall promptly deliver such Proceeds to the Agent, for the pro rata benefit of
the Banks, with any necessary endorsements. Until such Proceeds are delivered to
the Agent, such Proceeds shall be held in trust by such Debtor for the benefit
of the Agent and shall not be commingled with any other funds or property of any
Debtor.  All Proceeds of Collateral received by the Agent pursuant to this
Section may at the option of the Required Banks in the exercise of their
absolute discretion, (i) be applied by the Agent and the Banks to their
respective Obligations in such order and manner as they may elect in their
absolute discretion, or (ii) be deposited to the credit of any Debtor and held
as collateral for the Obligations or permitted to be used by such Debtor in the
ordinary course of its business.

     expense, at any time, or from time to time, all acts and things which the
     Agent deems necessary to protect, preserve, or realize upon the Collateral
     and the Agent's security interest therein.

     This power of attorney is a power coupled with an interest and shall be
irrevocable.  The Agent shall be under no duty to exercise or withhold the
exercise of any of the rights, powers, privileges, and options expressly or
implicitly granted to the Agent in this Agreement, and shall not be liable for
any failure to do so or any delay in doing so.  The Agent shall not be liable

     Section 5.2.  Setoff; Property Held by the Agent and the Banks.  If an
                   ------------------------------------------------
Event of Default shall have occurred and be continuing, the Agent, the
Syndication Agent, the Documentation Agent, the Alternate Currency Agent and
each Bank shall have the right to set off and apply against the Obligations, at
any time and without notice to any Debtor, any and all deposits (general or
special, time or demand, provisional or final) or other sums at any time
credited by or owing from the Agent, the Syndication Agent, the Documentation
Agent, the Alternate Currency Agent or any Bank to such Debtor whether or not
the Obligations are then due.  As additional security for the Obligations, each
Debtor hereby grants the Agent, the Syndication Agent, the Documentation Agent,
the Alternate Currency Agent and each Bank a security interest in all money,
instruments, and other property of such Debtor now or hereafter held by the
Agent, the Syndication Agent, the Documentation Agent, the Alternate Currency
Agent or any Bank, including without limitation, property held in safekeeping.
In addition to the Agent's, the Syndication Agent's, the Documentation Agent's,

Debtor.  In such event, the Debtors shall, at the request of the Agent, promptly

GUANRANTOR SECURITY AGREEMENT - Page 12
<PAGE>

or attempted performance to the Agent, together with interest thereon at the
Default Rate from and including the date of such expenditure to but excluding
the date such expenditure is paid in full. Notwithstanding the foregoing, it is
expressly agreed that the Agent shall not have any liability or responsibility
for the performance of any obligation of any Debtor under this Agreement.

     Section 5.4.  Subrogation.  If any of the Obligations are given in renewal
                   -----------
or extension or applied toward the payment of indebtedness secured by any Lien,

Agent and the Banks shall be, and are hereby, subrogated to all of the rights,
titles, interests and Liens securing the indebtedness so renewed, extended, or
paid.

     Section 5.5.  Agent's Duty of Care.  Other than the exercise of reasonable
                   --------------------
care and the physical custody of the Collateral while held by the Agent
hereunder, the Agent shall have no responsibility for or obligation or duty with
respect to all or any part of the Collateral or any matter or proceeding arising
out of or relating thereto, including without limitation any obligation or duty
to collect any sums due in respect thereof or to protect or preserve any rights
against prior parties or any other rights pertaining thereto, it being
understood and agreed that each Debtor shall be responsible for preservation of
all rights in the Collateral.  Without limiting the generality of the foregoing,
the Agent shall be conclusively deemed to have exercised reasonable care in the
custody of the Collateral if the Agent takes such action, for purposes of
preserving rights in the Collateral, as any Debtor may reasonably request in
writing, but no failure or omission or delay by the Agent in complying with any
such request by any Debtor, and no refusal by the Agent to comply with any such
request by any Debtor, shall be deemed to be a failure to exercise reasonable
care.

                                  ARTICLE VI

                                    Default
                                    -------

     Section 6.1.  Rights and Remedies.  If an Event of Default shall have
                   -------------------
occurred and be continuing, the Agent shall have the following rights and
remedies:

            (i)    In addition to all other rights and remedies granted to the
     Agent in this Agreement or in any other Loan Document or by applicable law,
     the Agent shall have all of the rights and remedies of a secured party
     under the UCC (whether or not the UCC applies to the affected Collateral).
     Without limiting the generality of the foregoing, the Agent may (1) without
     demand or notice to any Debtor, collect, receive, or take possession of the
     Collateral or any part thereof and for that purpose the Agent may enter
     upon any premises on which the Collateral is located and remove the
     Collateral therefrom or render it inoperable, and/or (2) sell, lease, or
     otherwise dispose of the Collateral, or any part thereof, in one or more
     parcels at public or private sale or sales, at the Agent's offices or
     elsewhere, for cash, on credit or for future delivery, and upon such other
     terms as the Agent may deem commercially reasonable.  The Agent shall have
     the right at any public sale or sales, and, to the extent permitted by
     applicable law, at any private sale or sales, to bid and become a


GUARANTOR SECURITY AGREEMENT - Page 13
<PAGE>

     purchaser of the Collateral or any part thereof free of any right or equity
     of redemption on the part of any Debtor, which right or equity of
     redemption is hereby expressly waived and released by each Debtor. Upon the
     request of the Agent, each Debtor shall assemble the Collateral and make it
     available to the Agent at any place designated by the Agent that is
     reasonably convenient to such Debtor and the Agent. Each Debtor agrees that
     the Agent shall not be obligated to give more than five days written notice
     of the time and place of any public sale or of the time after which any
     private sale may take place and that such notice shall constitute
     reasonable notice of such matters. The Agent shall not be obligated to make
     any sale of Collateral if it shall determine not to do so, regardless of
     the fact that notice of sale of Collateral may have been given. The Agent
     may, without notice or publication, adjourn any public or private sale or
     cause the same to be adjourned from time to time by announcement at the
     time and place fixed for sale, and such sale may, without further notice,
     be made at the time and place to which the same was so adjourned. The
     Debtors shall be jointly and severally liable for all expenses of retaking,
     holding, preparing for sale, or the like, and all attorneys' fees, legal
     expenses, and all other costs and expenses incurred by the Agent in
     connection with the collection of the Obligations and the enforcement of
     the Agent's rights under this Agreement. The Debtors shall remain liable
     for any deficiency if the Proceeds of any sale or other disposition of the
     Collateral are insufficient to pay the Obligations in full. The Agent, the
     Syndication Agent, the Documentation Agent, the Alternate Currency Agent
     and the Banks may apply the Collateral against the Obligations in such
     order and manner as the Agent may elect in its sole discretion. Each Debtor
     waives all rights of marshalling, valuation, and appraisal in respect of
     the Collateral.

            (ii)  The Agent may cause any or all of the Collateral held by it to
     be transferred into the name of the Agent or the name or names of the
     Agent's nominee or nominees.

            (iii) The Agent may collect or receive all money or property at any
     time payable or receivable on account of or in exchange for any of the
     Collateral, but shall be under no obligation to do so.

            (iv)  On any sale of the Collateral, the Agent is hereby authorized
     to comply with any limitation or restriction with which compliance is
     necessary, in the view of the Agent's counsel, in order to avoid any
     violation of applicable law or in order to obtain any required approval of

Agent shall be conclusively deemed to have exercised reasonable care in the
custody of the Collateral if the Agent takes such action, for purposes of
preserving rights in the Collateral, as Pledgor may reasonably request in
writing, but no failure or omission or delay by the Agent in complying with any
such request by Pledgor, and no refusal by the Agent to comply with any such
request by Pledgor, shall be deemed to be a failure to exercise reasonable care.

     may (A) without demand or notice to Pledgor, collect, receive, or take
     possession of the Collateral or any part thereof, (B) sell or otherwise
     dispose of the Collateral, or any part thereof, in one or more parcels at
     public or private sale or sales, at the Agent's offices or elsewhere, for
     cash, on credit, or for future delivery, and/or (C) bid and become a
     purchaser at any sale free of any right or equity of redemption in Pledgor,
     which right or equity is hereby expressly waived and released by Pledgor.
     Upon the request of the Agent, Pledgor shall assemble the Collateral and
     make it available to the Agent at any place designated by the Agent that is
     reasonably convenient to Pledgor and the Agent. Pledgor

PLEDGE AGREEMENT - Page 11
<PAGE>

     agrees that the Agent shall not be obligated to give more than five days
     written notice of the time and place of any public sale or of the time
     after which any private sale may take place and that such notice shall
     constitute reasonable notice of such matters. The Agent shall not be
     obligated to make any sale of the Collateral regardless of notice of sale
     having been given. The Agent may adjourn any public or private sale from
     time to time by announcement at the time and place fixed therefor, and such
     sale may, without further notice, be made at the time and place to which it
     was so adjourned. Pledgor shall be liable for all expenses of retaking,
     holding, preparing for sale, or the like, and all attorneys' fees and other
     expenses incurred by the Agent in connection with the collection of the
     Obligations and the enforcement of the Agent's rights under this Agreement,
     all of which expenses and fees shall constitute additional Obligations
     secured by this Agreement. The Agent may apply the Collateral against the
     Obligations in such order and manner as the Agent may elect in its sole
     discretion. Pledgor shall remain liable for any deficiency if the proceeds
     of any sale or disposition of the Collateral are insufficient to pay the
     Obligations. Pledgor waives all rights of marshalling in respect of the
     Collateral.

          (b) The Agent may cause any or all of the Collateral held by it to be
     transferred into the name of the Agent (if the Agent is not yet the
     registered owner of the Collateral) or the name or names of the Agent's
     nominee or nominees.

          (c) The Agent may collect or receive all money or property at any time
     payable or receivable on account of or in exchange for any of the
     Collateral, but shall be under no obligation to do so.

          (d) The Agent shall have the right, but shall not be obligated to,
     exercise or cause to be exercised all voting, consensual, and other powers
     of ownership pertaining to the Collateral[, including, without limitation,
     all rights, titles and interests of Pledgor as general partner of the
     Partnership,] [and Pledgor shall deliver to the Agent, if requested by the
     Agent, irrevocable proxies with respect to the Collateral in form
     satisfactory to the Agent.] [CellStar International: and shall no longer be
     required to vote in accordance with Pledgor's directions; and in the event
     that the Agent is not yet the registered owner of the Collateral, Pledgor
     shall deliver to Agent, if requested by the Agent, irrevocable proxies with
     respect to the Collateral in form satisfactory to the Agent.]

          (e) The Agent may notify or require Pledgor to notify parties
     obligated under any accounts, instruments, contracts or agreements which
     are part of the Collateral, [including without limitation the Partnership
     Agreements,] to make payment directly to the Agent, and the Agent may take
     possession of all proceeds of any such instruments and contracts in
     Pledgor's possession. Any such payments or distributions received by
     Pledgor after an Event of Default shall, until paid or delivered to the
     Agent, be held by Pledgor in trust as additional security for the
     Obligations.

<PAGE>

          (f)     [Pledgor hereby acknowledges and confirms that the Agent may
     be unable to effect a public sale of any or all of the Collateral by reason
     of certain prohibitions contained in the Securities Act of 1933, as
     amended, and applicable state securities laws and may be compelled to
     resort to one or more private sales thereof to a restricted group of
     purchasers who will be obligated to agree, among other things, to acquire
     any shares of the Collateral for their own respective accounts for
     investment and not with a view to distribution or resale thereof. Pledgor
     further acknowledges and confirms that any such private sale may result in
     prices or other terms less favorable to the seller than if such sale were a
     public sale and, notwithstanding such circumstances, agrees that any such
     private sale shall be deemed to have been made in a commercially reasonable
     manner, and the Agent shall be under no obligation to take any steps in
     order to permit the Collateral to be sold at a public sale. The Agent shall
     be under no obligation to delay a sale of any of the Collateral for any
     period of time necessary to permit any issuer thereof to register such
     Collateral for public sale under the Securities Act of 1933, as amended, or
     under applicable state securities laws.] [CellStar International: Pledgor
     hereby acknowledges and confirms that under applicable Hong Kong law the
     Agent cannot effect a public sale of any or all of the Collateral. Pledgor
     further acknowledges and confirms that if a private sale results in prices
     or other terms less favorable to the seller than may have resulted if such
     sale were a public sale, such circumstances shall not cause such sale to be
     deemed not to have been made in a commercially reasonable manner. Nothing
     in this Agreement shall prohibit a public sale of the Collateral if any
     change in circumstances or applicable law otherwise results in the
     availability of public sale with respect to the Collateral.]

          (g)     On any sale of the Collateral, the Agent is hereby authorized
     to comply with any limitation or restriction with which compliance is
     necessary, in the view of the Agent's counsel, in order to avoid any
     violation of applicable law or in order to obtain any required approval of
     the purchaser or purchasers by any applicable governmental authority.

          (h)     The Agent may subrogate to all of Pledgor's interests, rights,
     and remedies with respect to any of the Collateral.

                                   --------

     THIS GUARANTY ("Guaranty"), dated as of ________________, 199__, is
                     --------
executed by the undersigned guarantors (each a "Guarantor" and, collectively,
                                                ---------
the "Guarantors"), for the benefit of each of the banks or lending institutions
     ----------
(each, a "Bank" and, collectively, the "Banks") which is or may from time to
          ----                          -----
time become a signatory to the Credit Agreement (hereinafter defined) or any
successor or permitted assignee thereof, and Chase Bank of Texas, National

national banking association ("Chase"), as agent for itself and each of the
                               -----
other Banks (Chase in such capacity, together with its successors in such
capacity, the "Agent").
               -----

     WHEREAS, Cellstar Corporation, a Delaware corporation (the "Borrower"), the
                                                                 --------
Banks, The First National Bank of Chicago, as Syndication Agent, National City
Bank, as Documentation Agent, The Chase Manhattan Bank, as Alternate Currency
Agent and the Agent are parties to that certain Amended and Restated Credit
Agreement dated as of August 2, 1999 (as the same may be amended, supplemented
or modified from time to time, the "Credit Agreement"); and
                                    ----------------

     WHEREAS, as a condition to the Credit Agreement, each Guarantor is required
to execute and deliver this Guaranty.

     NOW, THEREFORE, for valuable consideration, the receipt and adequacy of
which are hereby acknowledged, the Guarantors hereby jointly and severally,
irrevocably and unconditionally guarantee to the Agent, the Syndication Agent,
the Documentation Agent, the Alternate Currency Agent and the Banks the full and
prompt payment and performance of the Guaranteed Indebtedness (hereinafter
defined), this Guaranty being upon the following terms:

     1.  The term "Guaranteed Indebtedness", as used herein, means all of the
                   -----------------------
"Obligations", as defined in the Credit Agreement. The term "Guaranteed
                                                             ----------
Indebtedness" shall include any and all post-petition interest and expenses
- ------------
(including reasonable attorneys' fees) whether or not allowed under any
bankruptcy, insolvency, or other similar law.  All other capitalized terms used
and not otherwise defined herein shall have their respective meanings as set
forth in the Credit Agreement.

     2.  This instrument shall be an absolute, continuing, irrevocable, and
unconditional guaranty of payment and performance, and not a guaranty of
collection, and each Guarantor shall remain liable on its obligations hereunder
until the payment and performance in full of the Guaranteed Indebtedness. No
set-off, counterclaim, recoupment, reduction, or diminution of any obligation,
or any defense of any kind or nature which Borrower may have against the Agent,
the Syndication Agent, the Documentation Agent, the Alternate Currency Agent,
any Bank or any other party, or which any Guarantor may have against Borrower,
the Agent, the Syndication Agent, the Documentation Agent, the Alternate
Currency Agent, any Bank or any other party, shall be available to, or shall be
asserted by, any Guarantor against the Agent, the Syndication Agent, the

GUARANTY - Page 1
<PAGE>

Documentation Agent, the Alternate Currency Agent, any Bank or any subsequent
holder of the Guaranteed Indebtedness or any part thereof or against payment of
the Guaranteed Indebtedness or any part thereof.

     3.   The obligations of each Guarantor hereunder shall be limited to an
aggregate amount equal to the largest amount that would not render its
obligations hereunder subject to avoidance under Section 548 of the United
States Bankruptcy Code or to being set aside, avoided, or annulled under any
applicable state law relating to fraudulent transfers or fraudulent obligations.

     4.   If any Guarantor becomes liable for any indebtedness owing by Borrower
to the Agent, the Syndication Agent, the Documentation Agent, the Alternate
Currency Agent or any Bank by endorsement or otherwise, other than under this
Guaranty, such liability shall not be in any manner impaired or affected hereby,
and the rights of the Agent, the Syndication Agent, the Documentation Agent, the
Alternate Currency Agent and the Banks hereunder shall be cumulative of any and
all other rights that any of them may ever have against any Guarantor.  The
exercise by the Agent, the Syndication Agent, the Documentation Agent, the
Alternate Currency Agent or any Bank of any right or remedy hereunder or under
any other instrument, or at law or in equity, shall not preclude the concurrent
or subsequent exercise of any other right or remedy.

     5.   In the event of default by Borrower in payment or performance of the
Guaranteed Indebtedness, or any part thereof, when such Guaranteed Indebtedness
becomes due, whether by its terms, by acceleration, or otherwise, Guarantors
jointly and severally agree to promptly pay the amount due thereon to the Agent,
for the pro rata benefit of the Banks, without notice or demand in lawful
currency of the United States of America and it shall not be necessary for the
Agent, the Syndication Agent, the Documentation Agent, the Alternate Currency
Agent or any Bank, in order to enforce such payment by any Guarantor, first to
institute suit or exhaust its remedies against Borrower, any Guarantor or others
liable on such Guaranteed Indebtedness, or to enforce any rights against any
collateral which shall ever have been given to secure such Guaranteed
Indebtedness.  Notwithstanding anything to the contrary contained in this
Guaranty, each Guarantor hereby irrevocably subordinates to the prior
indefeasible payment in full of the Guaranteed Indebtedness, any and all rights
such Guarantor may now or hereafter have under any agreement or at law or in
equity (including, without limitation, any law subrogating such Guarantor to the
rights of the Agent, the Syndication Agent, the Documentation Agent, the
Alternate Currency Agent and the Banks) to assert any claim against or seek
contribution, indemnification or any other form of reimbursement from Borrower
or any other party liable for payment of any or all of the Guaranteed
Indebtedness for any payment made by such Guarantor under or in connection with
this Guaranty or otherwise.

     6.   If acceleration of the time for payment of any amount payable by
Borrower under the Guaranteed Indebtedness is stayed upon the insolvency,
bankruptcy, or reorganization of Borrower, all such amounts otherwise subject to
acceleration under the terms of the Guaranteed Indebtedness shall nonetheless be
jointly and severally payable by the Guarantors hereunder forthwith on demand by
the Agent.

GUARANTY - Page 2

     7.   Each Guarantor hereby agrees that its obligations under this Guaranty
shall not be released, discharged, diminished, impaired, reduced, or affected
for any reason or by the occurrence of any event, including, without limitation,
one or more of the following events, whether or not with notice to or the
consent of any Guarantor: (a) the taking or accepting of collateral as security
for any or all of the Guaranteed Indebtedness or the release, surrender,
exchange, or subordination of any collateral now or hereafter securing any or
all of the Guaranteed Indebtedness; (b) any partial release of the liability of
any Guarantor hereunder, or the full or partial release of any other guarantor
from liability for any or all of the Guaranteed Indebtedness; (c) any disability
of Borrower, or the dissolution, insolvency, or bankruptcy of Borrower, any
Guarantor, or any other party at any time liable for the payment of any or all

     8.   Each Guarantor represents and warrants to the Agent, the Syndication
Agent, the Documentation Agent, the Alternate Currency Agent and the Banks that:

          (a)  Each and every representation and warranty contained in the
     Credit Agreement is true and correct in all respects.

GUARANTY - Page 3
<PAGE>

          (b)  The value of the consideration received and to be received by
     such Guarantor as a result of Borrower, the Banks, the Syndication Agent,
     the Documentation Agent, the Alternate Currency Agent and the Agent
     entering into the Credit Agreement, the extensions of credit thereunder and
     such Guarantor executing and delivering this Guaranty is reasonably
     equivalent to or greater than the liability and obligation of such
     Guarantor hereunder, and such liability and obligation, the Borrower's
     entering into the Credit Agreement and the extensions of credit thereunder
     have benefitted and may reasonably be expected to benefit such Guarantor
     directly or indirectly.

          (c)  Such Guarantor has, independently and without reliance upon the
     Agent, the Syndication Agent, the Documentation Agent, the Alternate
     Currency Agent or any Bank and based upon such documents and information as
     such Guarantor has deemed appropriate, made its own analysis and decision
     to enter into this Guaranty.

          (d)  The ability of Borrower to borrow and obtain letters of credit
     from time to time under the Credit Agreement will enable such Guarantor to
     obtain credit, will benefit such Guarantor and the consolidated corporate
     group of which such Guarantor is a part and are necessary and convenient to
     the conduct, promotion and attainment of the business of such Guarantor.

          (e)  As additional consideration for entering into this Guaranty, such
     Guarantor has obtained certain rights under that certain Contribution and
     Indemnification Agreement of even date herewith, among the Borrower and the
     Guarantors.

          (f)  Such Guarantor has adequate capital to conduct its business as a
     going concern, as presently conducted and as proposed to be conducted; such
     Guarantor will be able to meet its obligations hereunder and in respect of
     its other existing and future indebtedness and liabilities as and when the
     same shall be due and payable; such Guarantor is not insolvent (as that
     term is defined in 11 U.S.C.(S) 101 or applicable law) and will not be
     rendered insolvent by its obligations hereunder, and the foregoing
     representations are supported by such Guarantor's internal projections and
     forecasts.

          (g)  Such Guarantor has determined that the execution and delivery of
     this Guaranty is to its advantage and benefit, taking into account all
     relevant facts and circumstances.

     9.   If an Event of Default shall have occurred and be continuing, the
Agent and each Bank shall have the right to set off and apply against this
Guaranty or the Guaranteed Indebtedness or both, at any time and without notice
to any Guarantor, any and all deposits (general or special, time or demand,
provisional or final) or other sums at any time credited by or owing from the
Agent, the Syndication Agent, the Documentation Agent, the Alternate Currency
Agent or any Bank to any Guarantor whether or not the Guaranteed Indebtedness is
then due and irrespective of whether or not

GUARANTY - Page 4
<PAGE>

the Agent, the Syndication Agent, the Documentation Agent, the Alternate
Currency Agent or any Bank shall have made any demand under this Guaranty. As
security for this Guaranty and the Guaranteed Indebtedness, each Guarantor
hereby grants the Agent, the Syndication Agent, the Documentation Agent, the
Alternate Currency Agent and each Bank a security interest in all money,
instruments, certificates of deposit, and other property of such Guarantor now
or hereafter held by the Agent, the Syndication Agent, the Documentation Agent,
the Alternate Currency Agent and each Bank, including without limitation,
property held in safekeeping. In addition to the Agent's, the Syndication
Agent's, the Documentation Agent's, the Alternate Currency Agent's and each
Bank's right of setoff and as further security for this Guaranty and the
Guaranteed Indebtedness, each Guarantor hereby grants the Agent, the Syndication
Agent, the Documentation Agent, the Alternate Currency Agent and each Bank a
security interest in all deposits (general or special, time or demand,
provisional or final) and all other accounts of such Guarantor now or hereafter
on deposit with or held by the Agent, the Syndication Agent, the Documentation
Agent, the Alternate Currency Agent or any Bank and all other sums at any time
credited by or owing from the Agent, the Syndication Agent, the Documentation
Agent, the Alternate Currency Agent or any Bank to such Guarantor. The rights
and remedies of the Agent, the Syndication Agent, the Documentation Agent, the
Alternate Currency Agent and each Bank hereunder are in addition to other rights
and remedies (including, without limitation, other rights of setoff) which the
Agent, the Syndication Agent, the Documentation Agent, the Alternate Currency
Agent and each Bank may have.

     10.  (a)  Each Guarantor hereby agrees that the Subordinated Indebtedness
(hereinafter defined) shall be subordinate and junior in right of payment to the
prior payment in full of all Guaranteed Indebtedness, and each Guarantor hereby
assigns the Subordinated Indebtedness to the Agent, for the pro rata benefit of
the Banks, as security for the Guaranteed Indebtedness.  If any sums shall be
paid to any Guarantor by Borrower or any other Person on account of the
Subordinated Indebtedness, such sums shall be held in trust by such Guarantor
for the benefit of the Agent and shall forthwith be paid to the Agent, for the
pro rata benefit of the Banks, without affecting the liability of any Guarantor
under this Guaranty and may be applied by the Banks against the Guaranteed
Indebtedness in such order and manner as they may determine in their absolute
discretion; provided, however, that so long as no Event of Default shall have
            --------  -------
occurred, Borrower shall be permitted to pay to any Guarantor, and each
Guarantor shall be permitted to receive and retain, payments on account of
Subordinated Indebtedness consisting of trade payables owing by Borrower to any
Guarantor.  Upon the request of the Agent, each Guarantor shall execute,
deliver, and endorse to the Agent, for the pro rata benefit of the Banks, such
documents and instruments as the Agent may request to perfect, preserve, and
enforce the rights of the Agent and the Banks hereunder.  For purposes of this
Guaranty, the term "Subordinated Indebtedness" means all indebtedness,
                    -------------------------
liabilities, and obligations of Borrower and the Subsidiaries, or any of them,
to any Guarantor, whether such indebtedness, liabilities, and obligations now
exist or are hereafter incurred or arise, or whether the obligations of Borrower
or such Subsidiary thereon are direct, indirect, contingent, primary, secondary,
several, joint, joint and several, or otherwise, and irrespective of whether
such indebtedness, liabilities, or obligations are evidenced by a note,
contract, open account, or otherwise, and irrespective of the Person or Persons
in whose favor such indebtedness,

GUARANTY - Page 5
<PAGE>

obligations, or liabilities may, at their inception, have been, or may hereafter
be created, or the manner in which they have been or may hereafter be acquired
by any Guarantor.

          (b)  Each Guarantor agrees that any and all liens, security interests,
judgment liens, charges, or other encumbrances upon the assets of Borrower and
the Subsidiaries, or any of them, securing payment of any Subordinated
Indebtedness shall be and remain inferior and subordinate to any and all liens,
security interests, judgment liens, charges, or other encumbrances upon such
assets securing payment of the Guaranteed Indebtedness or any part thereof,
regardless of whether such encumbrances in favor of any Guarantor or the Agent
presently exist or are hereafter created or attached.  No Guarantor shall (i)
file suit against Borrower or any Subsidiary or exercise or enforce any other
creditor's right it may have against Borrower or any Subsidiary, or (ii)
foreclose, repossess, sequester, or otherwise take steps or institute any action
or proceedings (judicial or otherwise, including without limitation the
commencement of, or joinder in, any liquidation, bankruptcy, rearrangement,
debtor's relief or insolvency proceeding) to enforce any liens, security
interests, collateral rights, judgments or other encumbrances held by any
Guarantor on assets of Borrower or any Subsidiary unless and until the
Guaranteed Indebtedness shall have been paid in full, no Letters of Credit are
outstanding, and the Commitments have expired or terminated.

          (c)  In the event of any receivership, bankruptcy, reorganization,
rearrangement, debtor's relief, or other insolvency proceeding involving
Borrower or any Subsidiary as debtor, the Agent shall have the right to prove
and vote any claim under the Subordinated Indebtedness and to receive, for the
benefit of the Banks, directly from the receiver, trustee or other court
custodian all dividends, distributions, and payments made in respect of the
Subordinated Indebtedness. The Agent, the Syndication Agent, the Documentation
Agent, the Alternate Currency Agent and the Banks may apply any such dividends,
distributions, and payments against the Guaranteed Indebtedness in such order
and manner as they may determine in their absolute discretion.

          (d)  Each Guarantor agrees that all promissory notes, accounts
receivable, ledgers, records, or any other evidence of Subordinated Indebtedness
shall contain a specific written notice thereon that the indebtedness evidenced
thereby is subordinated under the terms of this Guaranty.

     11.  No Guarantor shall prepay any Debt, except the Guaranteed
Indebtedness.

     12.  No amendment or waiver of any provision of this Guaranty or consent to
any departure by any Guarantor therefrom shall in any event be effective unless
the same shall be in writing and signed by the Agent and the Required Banks.  No
failure on the part of the Agent, the Syndication Agent, the Documentation
Agent, the Alternate Currency Agent or any Bank to exercise, and no delay in
exercising, any right, power, or privilege hereunder shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, power, or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power, or privilege. The remedies herein provided
are cumulative and not exclusive of any remedies provided by law.

GUARANTY - Page 6
<PAGE>

     13.  Any acknowledgment or new promise, whether by payment of principal or
interest or otherwise and whether by Borrower or others (including any
Guarantor), with respect to any of the Guaranteed Indebtedness shall, if the
statute of limitations in favor of any Guarantor against the Agent, the
Syndication Agent, the Documentation Agent, the Alternate Currency Agent or any
Bank shall have commenced to run, toll the running of such statute of
limitations and, if the period of such statute of limitations shall have
expired, prevent the operation of such statute of limitations.

     14.  This Guaranty is for the benefit of the Agent, the Syndication Agent,
the Documentation Agent, the Alternate Currency Agent and the Banks and their
respective successors and assigns, and in the event of an assignment of the
Guaranteed Indebtedness, or any part thereof, the rights and benefits hereunder,
to the extent applicable to the indebtedness so assigned, may be transferred
with such indebtedness. This Guaranty is binding not only on each Guarantor, but
on each Guarantor's successors and assigns. The Guarantors' obligations and
agreements hereunder are joint and several. The provisions of this Guaranty
shall apply to each Guarantor individually and collectively.

     15.  Each Guarantor recognizes that the Agent, the Syndication Agent, the
Documentation Agent, the Alternate Currency Agent and the Banks are relying upon
this Guaranty and the undertakings of each Guarantor hereunder in making
extensions of credit to Borrower under the Credit Agreement and further
recognizes that the execution and delivery of this Guaranty is a material
inducement to the Agent, the Syndication Agent, the Documentation Agent, the
Alternate Currency Agent and the Banks in entering into the Credit Agreement.
Each Guarantor hereby acknowledges that there are no conditions to the full
effectiveness of this Guaranty.

     16.  THIS GUARANTY IS EXECUTED AND DELIVERED AS AN INCIDENT TO A LENDING
TRANSACTION NEGOTIATED, CONSUMMATED, AND PERFORMABLE IN DALLAS COUNTY, TEXAS,
AND SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE
OF TEXAS.

     17.  Guarantors jointly and severally agree to pay on demand all attorneys'
fees and all other costs and expenses incurred by the Agent and each Bank in
connection with the preparation, administration, enforcement, or collection of
this Guaranty.

     18.  Each Guarantor hereby waives promptness, diligence, notice of any
default under the Guaranteed Indebtedness, demand of payment, notice of
acceptance of this Guaranty, presentment, notice of protest, notice of dishonor,
notice of intent to accelerate, notice of acceleration, notice of the incurring
by Borrower of additional indebtedness, and all other notices and demands with
respect to the Guaranteed Indebtedness and this Guaranty.

     19.  Each Guarantor agrees that the Agent, the Syndication Agent, the
Documentation Agent, the Alternate Currency Agent and each Bank may exercise any
and all rights granted to them

GUARANTY - Page 7
<PAGE>

under the Credit Agreement and the other Loan Documents without affecting the
validity or enforceability of this Guaranty.

     20.  Each Guarantor hereby represents and warrants to the Agent, the
Syndication Agent, the Documentation Agent, the Alternate Currency Agent and the
Banks that such Guarantor has adequate means to obtain from the Borrower and the
Subsidiaries on a continuing basis information concerning the financial
condition and assets of the Borrower and the Subsidiaries and that such
Guarantor is not relying upon the Agent, the Syndication Agent, the
Documentation Agent, the Alternate Currency Agent or any Bank to provide (and
neither the Agent, the Syndication Agent, the Documentation Agent, the Alternate
Currency Agent nor any Bank shall have any duty to provide) any such information
to such Guarantor either now or in the future.

     21.  THIS GUARANTY REPRESENTS THE FINAL AGREEMENT AMONG THE PARTIES AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.  THERE ARE NO ORAL AGREEMENTS AMONG THE PARTIES.

     22.  Each Guarantor acknowledges that it has had the benefit of legal
counsel of its own choice and has been afforded an opportunity to review this
Guaranty with its legal counsel and that this Guaranty shall be construed as if
jointly drafted by the Guarantors and the Agent.

     23.  TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH GUARANTOR
HEREBY IRREVOCABLY AND EXPRESSLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY
ACTION, PROCEEDING, OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT OR
OTHERWISE) ARISING OUT OF OR RELATING TO THIS GUARANTY, THE CREDIT AGREEMENT,
ANY OF THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR
THEREBY OR THE ACTIONS OF THE AGENT, THE SYNDICATION AGENT, THE DOCUMENTATION

               TERMS AND CONDITIONS FOR STANDBY LETTER OF CREDIT

          In consideration of the issuance of the letter of credit and all
renewals, extensions, replacements and amendments thereof (herein called the
"Credit") by Bank in accordance with this Application and Agreement (this
"Agreement"), the undersigned (hereinafter called "Applicants," whether one or
more) jointly and severally agree to the following terms and conditions.

     1.   Applicants promise to pay to Bank on demand at its office shown on
front, in United States currency as follows:

  A. As to drafts, draws, demands, or other evidence of amounts drawn under or
purporting to be drawn under the Credit which are payable in United States
currency, the amount paid thereon, or, if so demanded by Bank, to pay Bank at
its office in advance the amount required to pay such drafts, draws, demands or
other evidence of amounts drawn under or purporting to be drawn under the
Credit;

  B. As to drafts, draws, demands, or other evidence of amounts drawn under or
purporting to be drawn under the Credit which are payable in currency other than
United States currency, either (i) the amount paid in the currency of the Credit
at the bank of Bank's choice in the country of such currency, or (ii) the
equivalent of the amount paid, in United States currency, at Bank's then current
selling rate for such currency;

  C. All taxes, levies, imposts, duties, charges, fees, deductions or
withholdings of any nature whatsoever and by whomsoever and wherever imposed in
connection with this Agreement, the Credit or any transactions hereunder or
thereunder, and

  D. Interest on all amounts owing to Bank hereunder at the maximum nonusurious
rate of interest permitted by applicable laws of the United States of America or
the State of Texas, from time to time in effect, whichever shall permit the
highest lawful rate (hereinafter called "the Highest Lawful Rate"). At all
times, if any, that Chapter One of Title 79, Texas Revised Civil Statues, 1925,
as amended, establishes the Highest Lawful Rate, the Highest Lawful Rate shall
be the "indicated" rate ceiling (as defined therein) from time to time in
effect. It is the intention of Applicants and Bank to conform strictly to
applicable usury laws. It is therefore agreed that: (i) if, for any reason, the
interest received for the actual period of the existence of any loan by Bank
hereunder exceeds the Highest Lawful Rate, Bank shall refund to Applicants the
amount of the excess or shall credit the amount of the excess against amounts
owing hereunder and shall not be subject to any of the penalties provided by law
for contracting for, charging, or receiving interest in excess of the Highest
Lawful Rate, (ii) the aggregate of all interest and other charges constituting
interest under applicable law and contracted for, chargeable or receivable under
this Agreement or otherwise in connection with this Agreement or the Credit,
shall not for the actual period of the existence of any loan hereunder exceed
the maximum amount of interest, nor produce a rate in excess of the Highest
Lawful Rate, (iii) if, for any reason, usurious interest is contracted for,
charged or received, then  the sole remedy of Applicants shall be to receive a
refund thereof or a credit on the accrued and unpaid interest and unpaid
principal under this Agreement equal to the usurious interest, it being agreed
that usurious interest shall mean the amount by which the total interest
contracted for, charged or received exceeds the amount of interest allowed by
applicable law; and this Agreement shall be automatically deemed reformed so as
to permit only the collection of the Highest Lawful rate of interest, and (iv)
determination of the rate  of interest on any loan evidenced hereby shall be
made by amortizing, prorating, allocating,, and spreading, in equal parts during
the period of the full stated term of such loan, all interest at any time
contracted for, charged or received from Applicants in connection with such
loan.

  E. Applicants assume all risks (political, economic or otherwise) of
disruptions or interruptions in currency exchange with respect to any demand
payable in other than United States currency, and if there is no then prevailing
exchange rate, Bank may obtain the non-United States currency from any
commercially reasonable source, in which case Applicants shall pay Bank's cost
therefor, inclusive of all expenses, in United States currency.

  F. Demand, for all purposes of this Agreement, shall be considered made at the
time Bank mails, telephones or otherwise sends notification to Applicants.

  G. Applicants agree to pay to Bank, any Member and/or Correspondent (as
hereinafter defined), or its correspondents, annually in advance not later than
forty-five (45) days prior to the then current expiration date of the Credit,
all fees and commissions owing to or which become owing in respect of the
Credit. Such fees and commissions shall be payable at the then current rate
charged by Bank and/or other entity(ies). Payment of such fees or commissions in
advance shall not affect the Bank's absolute right not to renew the Credit;
however, should Bank decide in its sole and absolute discretion not to renew the
Credit, Bank shall refund such advance payment to Applicants.

     2.   Applicants agree that if because of any law or regulation, or because
of any change in any existing law or regulation, or in the interpretation
thereof by any official authority, whether or not having the force of law, which
comes into effect after the date of this Agreement, (a) Bank or Applicants
should, with respect to this Agreement the Credit or any transactions hereunder
or thereunder, be subject to any tax, charge, fee, insurance premium, deduction
or withholding of any kind whatsoever, or (b) reserve requirements, or changes
in existing reserve requirements, should be imposed on Bank with respect to this
Agreement or the Credit or any transactions hereunder or thereunder, and if any
of the above-mentioned measures, or any other similar measure, should result in
(i) any increase in the cost to Bank of issuing and maintaining the Credit
pursuant to this Agreement or of any transaction under or in connection with the
Credit or this Agreement, or (ii) any reduction in the payment or deposit of any
amount (principal, interest, fee, commission or otherwise) receivable by Bank in
respect of the Credit or this Agreement or of any transaction under the Credit
or this Agreement, then Applicants shall pay to Bank upon demand such increased
cost or reduction, including such additional amounts as may be necessary so that
every net payment or deposit, after deduction or withholding for or on account
of such payment or deposit (including any taxes levied on additional amounts
paid pursuant to this paragraph), will not be less than the corresponding amount
provided for under the Credit or this Agreement before giving effect to such
increased cost or reduction; provided that in no event shall any additional
amounts which constitute interest exceed what is considered, together with other
interest payments, the Highest Lawful Rate.

     3.   Availments under the Credit may be effected through Bank or any
advising or confirming bank (the "Payor") at the then current buying rate of the
Payor for banker's sight drafts at the place from which the Payor is to receive
reimbursement under the terms of the Credit, it being understood and further
agreed: (a) that the amount(s) disbursed to the beneficiary(ies) relative
thereto may be in the currency local to the site of the Payor, and may be
reduced by any taxes and/or other charges whether of the Payor or otherwise, and
(b) that an advice of an availment under the Credit from the Payor shall be
sufficient evidence to Bank of an availment under the Credit, and such evidence
thereof shall be binding upon Applicants for the purposes of this Agreement.

     4.   If at any time(s) any funds and/or securities are paid to or deposited
with or under the control of Bank, not as payment under paragraph 1 hereof, but
to be held relative hereto, same shall be held as collateral security for the
Obligations (as hereinafter defined) and without Applicants having any right to
dispose of the same while any Obligations (as hereinafter defined) exist under
this Agreement, but with the discretionary right in Bank to release or surrender
all or any part of said funds and/or securities to or upon the order of
Applicants. If any such funds are available to Bank at its office in the
currency of the Credit at any time after any payment may become due hereunder,
Bank may (acting in each instance in its discretion and without being required
to make any prior demand for payment hereunder) apply all or any part thereof at
any time(s) on account of the Obligations (as hereinafter defined), irrespective
of the then current rate of exchange. Should the aggregate market value of any
such funds and/or securities at any time(s) suffer any decline, or should any
such property be unavialable at any time for any reason to Bank at its office or
fail to conform to legal requirements. Applicants will, upon demand, make such
payment(s) on account of the aforesaid Obligations, or as additional collateral
therefor, will deposit and pledge with Bank additional property that is
satisfactory to Bank. If any such funds as aforesaid be other than United States
Dollars and occasion arises for a refund by Bank of all or any portion thereof,
it shall be optional with Bank as to whether refund will be made (a) in United
States Dollars at the buying rate for the foreign currency on the date of
refund, or (b) in the amount and kind of the foreign currency on the date of
refund, or (c) by instructing a branch or correspondent of Bank to hold the
refundable amount of foreign currency for Applicants' account and risk.

     5.   Applicants hereby pledge, assign and hypothecate to Bank as security
for any and all of the obligations and liabilities of Applicants with respect
to the Credit, the Application portion of this Agreement (the "Application") and
this Agreement, whether hereinbefore or hereinafter referred to, now or
hereafter existing (herein called the "Obligations"), any and all property of
Applicants now or at any time(s) hereafter in Bank's possession or control or in
the possession or control of any third party acting in Bank's behalf, whether
for the express purpose of being used by Bank as collateral security or for
safekeeping or for any other or different purpose, including such property as
may be in transit by mail or carrier to or from Bank, a lien and security
interest being hereby given Bank upon and in any and all such property for the
aggregate amount of the Obligations; and Applicants authorize Bank, at Bank's
option, at any time(s), whether or not the property then held by Bank as
security hereunder is deemed by Bank to be adequate, to appropriate and apply to
or upon any and all of the Obligations, whether or not then due, any and all
monies now or hereafter with Bank on deposit or otherwise to the credit of
orbelonging to Applicants and in Bank's discretion, to hold any such monies as
security for any such Obligations until the exact amount thereof, if any, shall
have been definitely ascertained by Bank. Bank's rights, liens and security
interests hereunder shall continue unimpaired, and Applicants shall be and
remain obligated in accordance with the terms and provisions hereof,
notwithstanding the release or substitution of any property which may be held as
collateral hereunder at any time(s) or of any rights or interests therein, or
any delay, extension of time, renewal, compromise or other indulgence granted by
Bank in reference to any of the Obligations, or any promissory note, draft, bill
of exchange or other instrument given Bank in connection with any of the
Obligations, Applicants, and each of them individually, hereby waiving notice of
any such delay, extension, release, substitution, renewal, compromise or other
indulgence, and hereby consenting to be bound thereby as fully and effectually
as if Applicants had expressly agreed thereto in advance.

     6.   Applicants agree at any time and from time to time, on demand, (i) to
deliver, convey, transfer or assign to Bank, as security for any and all of the
Obligations, and also for any and all other obligations and/or liabilities,
absolute or contingent, due or to become due, which are now, or may at any time
hereafter, be owing by Applicants to Bank, additional security of a value and
character satisfactory to Bank, or (ii) to make such cash payment(s) in partial
or full satisfaction of the Obligations of such other obligations or liabilities
as Bank in its sole discretion may require.

     7.   Bank is hereby authorized, as its option and without any obligation to
do so, to transfer to and/or register in the name(s) of Bank's nominee(s) all or
any part of the property which may be held by it as security at any time(s)
hereunder, and to do so before or after the maturity of any of the Obligations
and with or without notice to Applicants.

     8.   The word "property" as used herein includes goods and merchandise (as
well as any and all documents relative thereto), securities, funds, monies
(whether United States currency or otherwise), choses in action and any and all
other forms of property, whether real, personal or mixed, tangible or
intangible, and any right or interest of Applicants, or any one or more of them,
therein or thereto. Bank is authorized, at its option, to file financing
statement(s) and continuation statement(s) without the signature of Applicants
with respect to any of the property, and Applicants jointly and severally agree
to pay the cost of any such filing and to sign upon request any instruments,
documents or other papers which Bank may require to perfect its security
interest in the property. A cartoon, photographic or other reproduction of this
Agreement shall be sufficient as a financing statement.

     9.   No proceeds of the Credit will be used for any purpose which would
constitute the Credit a "purpose credit" within the meaning of Regulation U of
the Board of Governors of the Federal Reserve System.

     10.  Applicants jointly and severally represent and warrant that (a) each
of them which is not a natural person is duly organized in good standing and
validly existing with full power and authority to execute this Agreement; (b)
the execution of this Agreement has been duly authorized by all necessary action
on the part of all Applicants and does not violate or contravene any law,
regulation, order or decree or the articles of incorporation, bylaws,
partnership agreement or any other organizational document of any Applicant; (c)
all requisite licenses, permits and franchises for the operation of Applicant's
business are in full force and effect; (d) any financial statements delivered to

(e) except as disclosed in writing to Bank in connection herewith, no litigation
or administrative proceeding is pending or threatened against any Applicant; and
(f) each Applicant has filed all tax returns required to have been filed and
paid all taxes shown thereon to be due. Applicants further represent and warrant
to Bank that Applicants are not now in violation of any applicable limitations
on the aggregate amount of loans that may be made to a borrower by any lender
and that issuance of the Credit by Bank will not be, or cause the aggregate
credit outstanding to any or all Applicants to exceed such limitations, and
Applicants covenant and agree that Applicants will at all times during the term
of this Agreement fully comply with and fully advise Bank and Member, if any, of
all circumstances relevant to, all applicable lending limits.

     11.  Upon the non-performance of any of the promises to pay herein set
forth, or upon the non-payment of any of the Obligations or other obligations or
liabilities of Applicants herein, or upon the failure of Applicants to furnish
satisfactory additional collateral or to make payments on account as hereinabove
agreed or to perform or comply with any of the other terms or provisions of this
Agreement, or in the event of default under any security agreement or guaranty
or other document securing or guaranteeing Applicants payment and performance of
the Obligations, or should any information supplied on behalf of Applicants
prove to be incorrect, false or misleading, or in the event of the death.
Insolvency, business failure, dissolution or termination of existence of any
Applicant, or in case any petition in bankruptcy is filed by or against any
Applicant, or any proceeding is commenced for the relief or readjustment of any
indebtedness of any Applicant, either through reorganization, composition,
extension or otherwise, or if any Applicant should make an assignment for the
benefit of creditors or take advantage of any insolvency law, or if a receiver
for any property of any Applicant should be appointed at any time, and in each
case any of the foregoing is initiated under laws or regulations of any
jurisdiction relating to the relief of debtors, then upon such occurrence, any
or all of the Obligations shall, at Bank's option, become due and payable
immediately, without demand or notice, notice of acceleration and of intention
to accelerate being hereby expressly waived by each Applicant.

     12.  Upon Applicants' failure to pay any Obligation when due, as aforesaid,
or upon the occurrence of any of the events described in paragraph 11 above,
Bank shall have, in addition to all other rights and remedies allowed by law,
the right immediately, without demand for performance and without notice of
intention to sell or of the time or place of sale or of redemption or other
notice or demand whatsoever to any Applicant, all of which are hereby expressly
waived, and without advertisement, to sell at any broker's board, or at public
or private sale, or to grant options to purchase, or otherwise to realize upon
the whole or from time to time any part of the collateral upon which Bank shall
have a security interest or lien as aforesaid, or any interest which Applicants
may have therein, and after deducting from the proceeds of sale or other
disposition of the said collateral all expenses (including but not limited to
reasonable attorney's fees for legal services of every kind and other expenses
as set forth below) shall apply the residue of such proceeds toward the payment
of any of the Obligations, in such order as Bank shall elect, and whether then
due or not due, Applicants remaining liable for any deficiency remaining unpaid
after such application. If notice of any sale or other disposition is required
by law to be given, each Applicant hereby agrees that a notice sent at least two
(2) days before the time of any intended public sale or of the time after which
any private sale or other disposition of the said collateral is to be made,
shall be reasonable notice of such sale or other disposition. Applicants also
agree to assemble the said collateral at such place or places as Bank designates
by written notice. At any such sale or other disposition, Bank may itself
purchase the whole or any part of the said collateral sold, free from any right
of redemption on the part of Applicants and free of any right to require sale in
inverse order of alienation, which rights are hereby waived and released.
Applicants agree that the said collateral secures, and further agree to pay on
demand, whether or not any default by Applicants has occurred, all expenses
(including but not limited to: reasonable attorneys' fees for legal services of
every kind, the cost of any Insurance and the payment of all taxes or other
charges) of, or incidental to, the custody, care, appraisal, sale or collection
of, or realization upon, any of the said collateral or in any way relating to
the enforcement or protection of Bank's rights hereunder. Where applicable, Bank
shall have, to the maximum extent permitted by applicable law, in addition to
and cumulative of the rights hereinabove provided, all of the rights and
remedies provided to a secured party by the Uniform Commercial Code in effect in
the State of Texas on the date of this Agreement.

     13.  No delay on the part of Bank in exercising any power of sale, lien,
option or other right hereunder, and no notice or demand which may be given or
made upon Applicants by Bank with respect to any power of sale, lien or other
right hereunder, shall constitute a waiver thereof or limit or impair the right
of Bank to take any action or to exercise any power of sale, lien, option or any
other right hereunder, without demand or notice or prejudice to the rights of
Bank as against Applicants in any respect. Any and all rights and liens of Bank
hereunder shall continue unimpaired, and Applicants shall be and remain
obligated in accordance with the terms and provisions hereof, notwithstanding
the release or substitution of any property as referred to herein, or of any
rights or interests therein, or any delay, extension of time, renewal,
compromise or other indulgence granted by Bank in reference to any of the
Obligations, Applicants each hereby waiving notice of any such delay, extension,
release, substitution, renewal, compromise or other indulgence, and each hereby
consenting to be bound thereby as fully and effectually as if Applicants had
expressly and specifically agreed thereto.

     14.  The users and beneficiaries of the Credit shall be deemed Applicants'
agents, and Applicants assume all risks of the acts or omissions of the users or
beneficiaries of the Credit. Neither Bank nor its correspondents or affiliates
shall assume any liability to anyone for failure to pay or accept if such
failure is due to any restriction in force at the time and place of presentment,
and Applicants agree to indemnify Bank from any consequences that may arise
therefrom. Neither Bank or Bank's correspondents or affiliates shall be liable
or responsible in any respect for any (a) error, omission, interruption or delay
in transmission, dispatch or delivery of any one or more messages or advices in
connection with the Application or the Credit, whether transmitted by cable,
radio, telegraph, twx, wireless, mail, electronic mail, telex, telefax,
telecopy, SWIFT, or otherwise and despite any cipher or code which may be
employed, or (b) errors in translation or for errors in interpretation of
technical terms, or (c) action, inaction or omission which may be taken or
suffered by it or them in good faith or through inadvertence in identifying or
failing to identify any beneficiary(ies) or otherwise in connection with the
Credit, or (d) validity, sufficiency or genuineness of document(s) even if such
document(s) should in fact prove to be in any or all respects invalid or
insufficient, fraudulent or forged, or (e) act, error, neglect or default,
omission, insolvency or failure in business of any of Bank's correspondents. The
happening of any one or more of the contingencies described above shall not
affect, impair or prevent the vesting of any of Bank's rights or powers
hereunder. In furtherance and extension and not in limitation of the specific
provisions hereinbefore set forth, it is hereby further agreed that any action,
inaction, or omission taken or suffered by Bank or by any of its correspondents
under or in connection with the Credit or the relative drafts, demands,
documents or property. If in good faith and in conformity with such foreign or
domestic laws, customs or regulations as Bank or any of its correspondents may
deem to be applicable thereto, shall be binding upon Applicants and shall not
place Bank or any of its correspondents under any resulting liability to
Applicants. If the Credit or this Agreement shall be terminated or revoked by
operation of law as to any Applicant, or if any Applicant shall restrain the
payment of the Credit by court order or any other means, or if this Agreement or
the Credit are amended, modified, revoked or cancelled as provided for herein
and any dispute, claim, demand or cause of action arises with respect thereto.
Applicants will jointly and severally indemnify and save Bank harmless from any
and all loss, cost, damage, expense, suit, claim, cause of action, judgment and
attorneys' fees which may be suffered or incurred by Bank, whether caused in
whole or in part by the negligence of Bank or any correspondent or affiliate of
Bank.

     15.  The Credit and this Agreement may be amended, modified, cancelled or
revoked only upon the receipt by Bank from all Applicants of a written request
therefor, and then only such terms and conditions as Bank may prescribe and then
only by a writing signed by all Applicants, the beneficiaries and Bank.
Notwithstanding the foregoing, however, Bank may, upon receipt of a written
request therefor, signed by all Applicants, extend the expiration date and/or
increase the amount of the Credit without the written or oral acceptance or
consent of any or all beneficiaries of the Credit. Bank is authorized without
reference to or approval by any Applicant to set forth the terms appearing on
the Application portion hereof in the Credit and to modify or alter such terms
in such language as Bank may deem appropriate, with such variations from such
terms as Bank may at its discretion determine (which determination shall be
conclusive and binding upon Applicants) are necessary and are not materially
inconsistent with such terms.

     16.  Notwithstanding anything herein (except paragraph 17) to the contrary,
it is understood and agreed that, if the Credit is issued in favor of a
sovereign or commercial entity which is to issue a commitment or guarantee on
Applicants' behalf in connection herewith, each Applicant shall remains liable
on the Credit until Bank is fully released in writing by such entity. Applicants
jointly and severally agree to pay (a) all costs and expenses incurred by Bank
in connection of amounts advanced under the Credit and any and all other amounts
remaining unpaid hereunder through probate, reorganization, bankruptcy or any
other proceeding and (b) reasonable attorneys' fees when and if collection of
any such amount is placed in the hands of an attorney for collection after
default.

     17.  Notwithstanding anything contained herein or in any other separate
security agreement or other document executed heretofore, herewith or hereafter
in connection with or related to this credit obligation, if this is a consumer
credit obligation (as defined or described in 12 C.F.R. 227. Regulation AA,
promulgated by the Federal Reserve Board), the security for this credit
obligation shall not extend to any non-possessory security interest in household
goods (as defined in said Regulation AA) other than a purchase money security
interest, and no waiver of any notice contained herein or therein shall be
construed under any circumstances to extend to any waiver of notice prohibited
by Regulation AA.

     18.  This Agreement and the Credit are subject to and incorporate fully
herein (except as expressly modified herein or in the Credit) the Uniform
Customs and Practice for Documentary Credits (1993 Revision). International
Chamber of Commerce Publication No. 500, (hereinafter referred to as "The
Uniform Customs"). This Agreement and the rights of Applicants and Bank
hereunder shall be subject to and governed by the substantive laws of the State
of Texas, without regard to the rules regarding conflicts of laws, except when
the substantive laws of the State of Texas conflict with the Uniform Customs, in
which event the provisions of the Uniform Customs shall govern.

     19.  If the Credit is governed by the laws of a foreign jurisdiction, the
Credit may require Bank to pay funds as Bank's primary obligation in the event
Bank is, or in good faith deems itself to be, obligated to advance funds to the
beneficiary(ies) hereof. Applicants hereby expressly jointly and severally agree
to reimburse Bank on demand for all such advances made, notwithstanding any
expiration or cancellation of the Credit by Bank or under Texas law or the
Uniform Customs and even though Applicants may have an unresolved controversy
with a third party or the beneficiary(ies) related to the transaction for which
the Credit is being sought, including the proper interpretation of the law of
such foreign jurisdiction. In the event Applicants have a dispute with the
beneficiary(ies) or a third party, Applicants are required to reimburse Bank on
demand, and Applicants' remedy is to seek reimbursement from the
beneficiary(ies) or the third party. Bank is expressly authorized to presume
that all demands for payment made by the beneficiary(ies) hereof are made in
accordance with such foreign law.

     20.  Unless otherwise expressly stated herein or in the Credit, neither the
Credit nor this Agreement may be assigned by the beneficiary(ies) or any
Applicant without the prior written consent of Bank. Bank may assign or transfer
the Credit or this Agreement, or any instrument(s) evidencing all or any of the
Obligations, and may deliver all or any of the property then held as security
therefor, to the transferee(s) of Bank, who shall thereupon become vested with
all of the powers and rights in respect thereof given to Bank herein or in the
instrument(s) transferred, and Bank shall thereafter be forever relieved and
fully discharged from any liabilities or responsibility with respect thereto,
but Bank shall retain all rights and powers hereby given with respect to any and
all instrument(s), rights or property not so transferred.

     21.  This Agreement, the Application and the Credit constitute the entire
agreement among the parties hereto, except for such agreements executed in
connection herewith which specifically refer to this Agreement, the Application
or the Credit or which grant to Bank a lien or security interest to secure any
debts or obligations of any Applicant, regardless of any reference or lack
thereof to this Agreement, Application or the Credit. Terms used herein in the
plural number shall be construed as singular as the context requires and vice
versa.

     22.  Although the Credit may refer to a particular agreement or other
obligation to the beneficiary(ies) executed by Applicants, the terms of such
agreement are not in any manner incorporated herein. Bank shall therefore make
payment upon demand under the Credit unless it appears that such demand, on its
face, does not comply with the terms of the Credit. Such payment shall be made
without regard to performance of any obligation by any contracting party under
such agreement.

     23.  Applicants agree that at all times now and hereafter they will
indemnify and save Bank harmless from and against all suits, judgments,
liabilities, losses or damages to it arising in any manner, including negligence
on the part of Bank in connection with the Credit or this Agreement, unless due
to gross negligence or willful misconduct on the part of Bank and from and
against all costs, charges and expenses, including in connection with all legal
proceedings, whether groundless or otherwise, attorneys' fees, it being the
purpose of this Agreement to protect Bank fully in the premises.

     24.  Applicants agree that no acceptance or payment of overdrafts or
irregular drafts or of drafts with irregular documents attached shall, if
assented to or approved by any Applicant orally or in writing, or if Bank in
good faith accepts an indemnity limited to the actual damage, if any, caused by
such irregularity or discrepancy, impair any rights which Bank may have under
this Agreement. In case of any variation between the documents called for by the
Credit or this Agreement and the documents accepted by Bank or Bank's
correspondents. Applicants shall each be deemed conclusively to have waived any
right to object to such variation with respect to any action by Bank or Bank's
correspondents relating to such documents and to have ratified and approved such
action as having been taken on Applicant's direction, unless Applicants
Immediately upon receipt of such documents (and prior to receipt thereof by any
beneficiary or user of the Credit) file objection with Bank in writing, or
unless Bank has been provided with an indemnity, as aforesaid. Applicants
acknowledge and agree that, the information in the Application portion of this
Agreement may be transmitted to Bank and relied on by Bank in issuing the Credit
by any means acceptable to Bank, including without limitation, SWIFT, electronic
mail, telex, telephone, twx, telecopy or telefax. Applicants, Member and
Correspondent (both as hereinafter defined) agree to hold Bank harmless from and
against all claims, expenses, costs, liabilities, attorneys' fees, suits,
judgments, and causes of action arising out of any discrepancy between the
information in this Agreement, including without limitation, the Application,
and that transmitted to, or received by, Bank.

     25.  Issuance by Bank of the Credit applied for herein shal constitute
acceptance by Bank of this Agreement.

     26.  If this Agreement contains the signature of a bank which is subsidiary
of Chase Bank of Texas, National Association (hereinafter referred to as the
"Member") or of a correspondent bank of Bank (hereinafter referred to as the
"Correspondent"), then this paragraph shall be applicable. In consideration of
Bank's issuing the Credit at the request of Correspondent or Member, as
applicable, Correspondent or Member as applicable, agrees that it is an
Applicant hereunder with respect to Bank, and it agrees to reimburse Bank on
demand and authorizes bank, without demand or any notice whatsoever to charge,
setoff against and otherwise exercise any rights Bank may have with respect to,
any monies now or hereafter on deposit with or otherwise to the credit of or
belonging to Correspondent or Member, as applicable, at or with Bank for any and
all Obligations hereunder, whether or not any demand has been made on Applicants
hereunder. As an Applicant hereunder, each Correspondent or Member Bank, as
applicable, makes the same representations, warranties, covenants and agreements
to Bank as the Applicants in paragraph 10 hereof and otherwise provided in this
Agreement; provided, however unless otherwise agreed to in writing, or stated
herein neither Member nor Correspondent agrees to furnish any security for this
Agreement or the Credit other than the aforementioned monies. Upon Member's or
Correspondent's, as applicable, payment to Bank of all Obligations hereunder,
Bank thereupon automatically, and without further action on the part of any
party, assigns and transfers its rights hereunder to Correspondent or Member, as
applicable, who shall be fully subrogated thereto, and Applicants agree that any
right, claim or cause of action which any of them may have hereunder or under
the Credit shall be made only against Correspondent or Member, as applicable,
and Applicants agree to indemnify and hold Bank harmless from and against any
claims, costs, expenses, suits or causes of action by Applicants or any
beneficiary or user of the Credit. Applicants hereby agree that Correspondent or
Member, as applicable, shall also (in addition to Bank) have the same rights,
remedies, security interests and other liens as are stated herein, to the same
effect as if additional paragraphs were fully written herein containing the same
terms but substituting "Correspondent" or "Member" for "Bank" throughout. All
references to secured party, beneficiary or other similar term contained in any
deed of trust, security agreement, financing statement or other document or
instrument executed contemporaneously herewith or previously executed by any of
the Applicants for the benefit of Member or Correspondent shall be deemed to
include Bank as well as Member or Correspondent. All such security agreements,
financing statements, deeds of trust and other documents and instruments and
instruments are amended to the extent necessary in order that the Obligations of
Applicants hereunder are secured thereby and by the collateral described therein
on a pari passu basis with, and in addition to, any other obligations secured
thereby.

     27.  [ ] If this box is checked this paragraph is applicable. Applicants
have requested Bank to issue a Credit which the Bank may, but is not required,
to renew on an annual basis until the "latest date" indicated on the Application
or such later date as any Applicant may hereafter request in writing. Applicants
agree that Bank has made no commitment to any beneficiary or any Applicant, and
that Bank has no obligation, to renew the Credit at or prior to the original or
any subsequent expiration date. Except as expressly provided in the Credit. Bank
shall have no liability to any beneficiary for the renewal of, or failure to
renew, the Credit for any reason. Except as hereinafter agreed, the Bank shall
not have any liability to Applicants due to the renewal of, or failure to renew,
the Credit for any reason. Except to the extent any notice may be required in
the Credit, Bank is not required to notify any beneficiary or Applicant of the
renewal, or failure to renew, the Credit. Subject to the other conditions and
indemnities in this Agreement, including negligence by Bank, Bank and Applicants
agree that Bank will not renew the Credit if it receives, and an authorized
officer of Bank acknowledges such receipt in writing, written notification from
any Applicant at least 14 days and not more than 30 days prior to the earliest
date on which, pursuant to the terms of the Credit, Bank must either renew or
decline to renew the Credit or notify beneficiary(ies) of its decision to renew
or not to renew the Credit. Such written notification must specify to the
satisfaction of Bank the Credit, the then current expiration date, and such
Applicant's request that the Credit not be renewed.

This written loan agreement represents the final agreement between the parties
and may not be contradicted by evidence of prior, contemporaneous, or
subsequent oral agreements of the parties.
There are no unwritten oral agreements between the parties.

             TERMS AND CONDITIONS FOR COMMERCIAL LETTER OF CREDIT

          In consideration of the issuance of the letter of credit and all
renewals, extensions, replacements and amendments thereof (herein called the
"Credit") by Chase Bank of Texas, National Association (the "Bank") in
accordance with this Application and Agreement (this "Agreement"), the
undersigned (hereinafter called "Applicants," whether one or more) jointly and
severally agree to the following terms and conditions:

     1.   Applicants promise to pay to Bank on demand at 717 Travis Street,
Houston, Harris County, Texas 77002, in United States currency as follows:

  A. As to drafts, demands, or acceptances drawn under or purporting to be drawn
under the Credit which are payable in United States currency: (a) in the case of
each sight draft or demand, the amount paid thereon, or, if so demanded by Bank,
to pay Bank in advance, the amount required to pay such drafts or demands; and
(b) in the case of each acceptance or time draft, the amount thereof on demand,
but in any event not later than one business day prior to maturity, or, in case
the acceptance is not payable at Bank's office, then on demand, but in any event
in time to reach the place of payment in the ordinary course of the mails not
later than one business day prior to maturity, it being understood that Bank
will notify Applicants of the amount and date of maturity of each such
acceptance;

  B. As to drafts, demands, or acceptances under or purporting to be under the
Credit which are payable in currency other than United States currency: (a) in
the case of each sight draft or demand, either (i) the amount paid in the
currency of the Credit at the bank of Bank's choice in the country of such
currency, or (ii) the equivalent of the amount paid, in United States currency,
at Bank's then current selling rate for such currency; and (b) in the case of
each acceptance of time draft, to pay Bank, on demand, but in any event in time
to reach the place of payment in the ordinary course of the mails not later than
one business day prior to maturity, either (i) the amount paid in the currency
of the Credit at the bank of Bank's choice in the country of such currency, or
(iii) the equivalent of the acceptance in United States currency at Bank's then
current selling rate for the currency in which the acceptance is payable;

  C. All taxes, levies, imposts, duties, charges, fees, deductions or
withholdings of any nature whatsoever and by whomsoever and wherever imposed in
connection with this Agreement the Credit or any transactions hereunder or
thereunder.

  D. All commissions of Bank, any Member or Correspondent (as hereinafter
defined) or its correspondents, as applicable, at the rate agreed upon or as
specified by Bank or such other entity, and all charges and expenses incurred by
Bank for or in connection with this Agreement, the Credit or any transaction
hereunder or thereunder; and

  E. Interest on all amounts owing to Bank hereunder at the Highest Lawful Rate
(as hereinafter defined) permitted by applicable laws of the United States of
America or the State of Texas, from time to time in effect, whichever shall
permit the highest lawful rate (hereinafter referred to as "the Highest Lawful
Rate"). At all times, if any, that Chapter One of Title 79, Texas Revised Civil
Statues, 1925, as amended, establishes the Highest Lawful Rate, the Highest
Lawful Rate shall be the "indicated" rate ceiling (as defined therein) from time
to time in effect. It is the intention of Applicants and Bank to conform
strictly to applicable usury laws. It is therefore agreed that: (i) if, for any
reason, the interest received for the actual period of the existence of any
loan by Bank hereunder exceeds the Highest Lawful Rate, Bank shall refund to
Applicants the amount of the excess or shall credit the amount of the excess
against amounts owing hereunder and shall not be subject to any of the penalties
provided by law for contracting for, charging, or receiving interest in excess
of the Highest Lawful Rate, (ii) the aggregate of all interest and other charges
constituting interest under applicable law and contracted for, chargeable or
receivable under this Agreement or otherwise in connection with this Agreement
or the Credit, shall not for the actual period of the existence of any loan
hereunder exceed the maximum amount of interest, nor produce a rate in excess of
the Highest Lawful Rate, (iii) if, for any reason, usurious interest is
contracted for, charged or received, then the sole remedy of Applicants shall be
to receive a refund thereof or a credit on the accrued and unpaid interest and
unpaid principal under this Agreement equal to the usurious interest. It being
agreed that usurious interest shall mean the amount by which the total interest
contracted for, charged or received exceeds the amount of interest allowed by
applicable law; and this Agreement shall be automatically deemed reformed so as
to permit only the collection of the Highest Lawful Rate of interest, and (iv)
determination of the rate of interest on any loan evidenced hereby shall be made
by amortizing, prorating, allocating, and spreading, in equal parts during the
period of the full stated term of such loan, all interest at any time contracted
for, charged or received from Applicants in connection with such loan.

  F. Applicants assume all risks (political, economic or otherwise) of
disruptions or interruptions in currency exchange with respect to any demand
payable in other than United States currency, and if there is no then prevailing
exchange rate, Bank may obtain the non-United States currency from any
commercially reasonable source, in which case Applicants shall pay Bank's cost
therefor, inclusive of all expenses, in United States currency.

  G. Demand, for all purposes of this Agreement, shall be considered made at the
time Bank mails, telephones or otherwise sends notification to Applicants.

     2.   Applicants agree that if because of any law or regulation, or because
of any change in any existing law or regulation, or in the interpretation
thereof by any official authority, whether or not having the force of law, which
comes into effect after the date of this Agreement, (a) Bank or Applicants
should, with respect to this Agreement, the Credit or any transactions hereunder
or thereunder, be subject to any tax, charge, fee, insurance premium, deduction
or withholding of any kind whatsoever, or (b) reserve requirements, or changes
in existing reserve requirements, should be imposed on Bank with respect to this
Agreement or the Credit or any transactions hereunder or thereunder, and if any
of the above-mentioned measures, or any other similar measure, should result in
(i) any increase in the cost to Bank of issuing and maintaining the Credit
pursuant to this Agreement or of any transaction under or in connection with the
Credit or this Agreement, or (ii) any reduction in the payment or deposit of any
amount (principal, interest fee, commission or otherwise) receivable by Bank in
respect of the Credit or this Agreement or of any transaction under the Credit
or this Agreement then Applicants shall pay to Bank upon demand such increased
cost or reduction, including such additional amounts as may be necessary so that
every net payment or deposit after deduction or withholding for or on account
of such payment or deposit (including any taxes levied on additional amounts
paid pursuant to this paragraph), will not be less than the corresponding amount
provided for under the Credit or this Agreement before giving effect to such
increased cost or reduction; provided that in no event shall any additional
amounts which constitute interest exceed what is considered, together with other
interest payments, the Highest Lawful Rate.

     3.   Applicants hereby recognize and admit the Bank's ownership of and
unqualified right to the possession and disposal of, and do hereby grant to Bank
a security interest in, all property shipped or warehoused under or pursuant to
or in connection with the Credit and in all things in any way relative thereto
and the drafts, demands and acceptances drawn thereunder, whether or not
released to or by Bank on trust or bailee receipt or other form of security
agreement and also in and to all shipping documents, warehouse receipts, trust
or bailee receipts, policies or certificates of insurance and any other
documents accompanying or relative to drafts drawn under the Credit, whether or
not released to Applicants on trust or bailee receipt or other form of security
agreement, and in and to the proceeds of each and all the foregoing, until such
time as all the obligations or liabilities of the Applicants pursuant to the
Credit, the Application and this Agreement, now or hereafter existing (the
"Obligations") have been fully paid and discharged; and that all or any of the
foregoing property and documents, and the proceeds of any thereof, coming into
the possession of Bank or any of its correspondents, may be held and disposed of
by Bank as hereinafter provided; and the receipt by Bank, or any of its
correspondents, at any time of other security, of whatsoever nature, including
cash, shall not be deemed a waiver of any of Bank's rights or powers granted or
acknowledged herein.

     4.   In the event that Bank delivers to Applicants or upon Applicant's
order any documents or any property with respect to the Credit prior to Bank's
having received reimbursement with respect to the relative drafts, acceptances,
demands or receipts as herein provided, Applicants further agree to execute and
deliver to Bank a trust receipt or other security agreement and a financing
statement or like statement all in form acceptable to Bank and pay all
attorneys', filing and recording fees.

     5.   Applicants hereby pledge, assign and hypothecate to Bank as security
for any and all of the Obligations, any and all property of Applicants now or at
any time(s) hereafter in Bank's possession or control, or that of any third
party acting in Bank's behalf whether for the express purpose of being used by
Bank as collateral security of for safekeeping or for any other purpose,
including such property as may be in transit by mail or carrier to or from Bank,
a lien and security interest being hereby granted Bank upon and in any and all
such property for the aggregate amount of the Obligations; and Applicants
authorize Bank, at Bank's option, at any time(s), whether or not the property
then held by Bank as security hereunder is deemed by Bank to be adequate, to
appropriate and apply upon any and all of the Obligations, whether or not then
due, any and all monies now or hereafter with Bank on deposit or otherwise to
the credit of or belonging to Applicants and in Bank's discretion, to hold any
such monies as security for Obligations until the exact amount of such
Obligations, if any, shall have been definitely ascertained by Bank. Bank's
rights, liens and security interests hereunder shall continue unimpaired, and
Applicants shall be and remain obligated in accordance with the terms and
provisions hereof, notwithstanding the release or substitution of any property
which may be held as collateral hereunder at any time(s) or of any rights or
interests therein, or any delay, extension of time, release, substitution,
waiver, renewal, compromise or other indulgence granted by Bank in reference to
any of the Obligations, or any promissory note, draft, bill of exchange or other
instrument given Bank in connection with any of the Obligations, Applicants, and
each of them individually, hereby waiving notice of any such delay, extension,
release, substitution, waiver, renewal, compromise or other indulgence, and
hereby consenting to be bound thereby as fully and effectually as if Applicants
had expressly agreed thereto in advance.

     6.   Applicants agree at any time and from time to time, on demand, (i) to
deliver, convey, transfer or assign to Bank, as security for any and all of the
Obligations, and also for any and all other obligations and/or liabilities,
whether absolute or contingent due or to become due, which are now, or may at
any time hereafter, be owing by Applicants to Bank, additional security of a
value and character satisfactory to Bank, or (ii) to make such cash payment(s)
in partial or full satisfaction of the Obligations of such other obligations or
liabilities as Bank in its sole discretion may require.

     7.   Bank is hereby authorized, as its option and without any obligation to
do so, to transfer to or register in the name(s) of Bank's nominee(s) all or
any part of the property which may be held by it as security at any time(s)
hereunder, and to do so before or after the maturity of any of the Obligations
and with or without notice to Applicants.

     8.   Upon the non-performance of any of the promises to pay herein set
forth, or upon the non-payment of any of the Obligations or other obligations or
liabilities of Applicants herein, or upon the failure of Applicants to furnish
satisfactory additional collateral or to make payments on account as hereinabove
agreed, or to perform or comply with any of the other terms or provisions of
this Agreement or in the event of default under any security agreement or
guaranty or other document securing or guaranteeing Applicants' payment or
performance of the Obligations, or should any information supplied on behalf of
Applicants prove to be incorrect, false or misleading, or in the event of the
death, insolvency, business failure, dissolution or termination or existence of
any Applicant or in case any petition in bankruptcy is filed by or against any
Applicant or any proceeding is commenced for the relief or readjustment of any
indebtedness of any Applicant either through reorganization, corporation,
extension or otherwise, or if any Applicant should make an assignment for the
benefit of creditors or take advantage of any insolvency law, or if a receiver
of any property of any Applicant should be appointed at any time, and in each
case any of the foregoing is initiated under laws or regulations of any
jurisdiction relating to the relief of debtors, then upon such occurrence, any
or all of the Obligations shall, at Bank's option, become due and payable
immediately, without demand or notice, notice of acceleration and of intention
to accelerate being hereby expressly waived.

<PAGE>

     9.   Upon Applicants' failure to pay any Obligation when due, as aforesaid,
or upon the occurrence of any of the events described in paragraph 8 above. Bank
shall have, in addition to all other rights and remedies allowed by law, the
right immediately, without demand for performance and without notice of
intention to sell or of the time or place of sale or of redemption or other
notice or demand whatsoever to any Applicant, all of which are hereby expressly
waived and without advertisement, to sell at any broker's board, or at public or
private sale, or to grant options to purchase, or otherwise to realize upon the
whole or from time to time any part of the collateral upon which Bank shall have
a security interest or lien as aforesaid, or any interest which Applicants may
have therein, and after deducting from the proceeds of sale or other disposition
of the said collateral all expenses (including but not limited to reasonable
attorneys' fees for legal services of every kind and other expenses as set forth
below) shall apply the residue of such proceeds toward the payment of any of the
Obligations, in such order as Bank shall elect, and whether then due or not due,
Applicants remaining liable for any deficiency remaining unpaid after such
application. If notice of any sale or other disposition is required by law to be
given, Applicants hereby agree that a notice sent at least two (2) days before
the time of any intended public sale or of the time after which any private sale
or other disposition of the said collateral is to be made, shall be reasonable
notice of such sale or other disposition. Applicants also agree to assemble the
said collateral at such place or places as Bank designates by written notice. At
any such sale or other disposition, Bank may itself purchase the whole or any
part of the said collateral sold, free from any right of redemption on the part
of Applicants and free of any right to require sale in inverse order of
alienation, which rights are hereby waived and released. Applicants agree that
the said collateral secures, and further agree to pay on demand, whether or not
any default by Applicants has occurred, all expenses (including but not limited
to, reasonable attorneys' fees for legal services of every kind, the cost of any
insurance and the payment of all taxes or other charges) of, or incidental to,
the custody, care, appraisal, sale or collection of, or realization upon, any of
the said collateral or in any way relating to the enforcement or protection of
Bank's rights hereunder. Where applicable, Bank shall have, to the maximum
extent permitted by applicable law, in addition to and cumulative of the rights
hereinabove provided, all of the rights and remedies provided to a secured party
by the Uniform Commercial Code in effect in the State of Texas on the date of
this Agreement.

     10.  Bank and any of its correspondents may receive and accept as "bills of
lading" under the Credit any documents issued or purporting to be issued by or
on behalf of any carrier which acknowledge receipt of property for
transportation, whatever the specific provisions of such documents, and the date
of each such document shall be deemed the date of shipment of the property
mentioned therein; and such documents shall be deemed in order if such date is
within the time limit fixed by the Credit, and Bank may receive and accept as
documents of insurance either insurance policies or insurance certificates.

     11.  In the event of any change or modification with respect to: (a) the
amount or duration of the Credit; (b) the time or place of shipment of any
property thereunder; (c) the drawing, negotiation, presentation, acceptance, or
maturity of any drafts, acceptances or other documents; or (d) any of the other
terms or provisions of the Credit such change or modification being done at the
request of any Applicant this Agreement shall be binding upon Applicants in all
respects with regard to the Credit so changed or modified, inclusive of any
action taken by Bank or any of its correspondents.

     12.  The users and beneficiaries of the Credit shall be deemed Applicants'
agents, and Applicants assume all risks of the acts or omissions of the users or
beneficiaries of the Credit. Neither Bank nor its correspondents shall assume
any liability to anyone for failure to pay or accept if such failure is due to
any restriction in force at the time and place of presentment and Applicants
agree to indemnify Bank from any consequences that may arise therefrom. Neither
Bank nor Bank's correspondents shall be responsible: (a) for existence,
character, quality, quantity, condition, packing, value, or delivery of the
property purporting to be represented by documents; (b) for any difference in
character, quality, quantity, condition, packing, or value of the property from
that expressed in documents; (c) for the validity, sufficiency, or genuineness
of documents, even if such documents should in fact prove to be in any or all
respects invalid, insufficient, fraudulent or forged; (d) for the time, place,
manner or order in which shipment is made; (e) for partial or incomplete
shipment, or failure or omission to ship any or all of the property referred to
in the Credit; (f) for the character, adequacy, validity or genuineness of any
insurance; (g) for the solvency or responsibility of any insurer, or for any
other risk connected with insurance; (h) for any deviation from instruction,
delay, default or fraud by the shipper or anyone else in connection with the
property or the shipping thereof or the documents; (i) for the solvency,
responsibility or relationship to the property of any party issuing any
documents in connection therewith; (j) for delay in arrival or failure to arrive
of either the property or any of the documents relating thereto; (k) for delay
in giving or failure to give notice of arrival or any other notice; (l) for any
breach of contract between the shippers or vendors and Applicants; (m) for
failure of any draft demand or acceptance to bear any reference or adequate
reference to the Credit or failure of documents to accompany and draft demand or
acceptance at negotiation, or failure to send forward documents apart from
drafts as required by the terms of the Credit (each of which provisions, if
contained in the Credit, may be waived by Bank); (n) for errors, omissions,
interruptions or delays in transmission or delivery of any messages by mail,
cable, telegraph, twx, wireless, telecopy, telefax, electronic mail, SWIFT or
otherwise, whether or not they be in or contain code; or, (o) for errors in
translation or for errors in interpretation of technical terms. Bank shall not
be responsible for any act, error, neglect or default, omission, insolvancy or
failure in business of any of its correspondents, and the happening of any one
or more of the contingencies referred to in the preceding sentence shall not
affect, impair or prevent the vesting of any of Bank's rights or powers
hereunder. In furtherance and extension and not in limitation of the specific
provisions hereinbefore set forth, it is hereby further agreed that any action,
inaction, or omission taken or suffered by Bank or by any of its correspondents
under or in connection with the Credit or the relative drafts, demands,
acceptances, documents or property, if in good faith and in conformity with such
foreign or domestic laws, customs or regulations as Bank or any of it
correspondents may deem to be applicable thereto, shall be binding upon
Applicants and shall not place Bank or any of its correspondents under any
resulting liability to Applicants. If the Credit or this Agreement shall be
terminated or revoked by operation of law as to any Applicant, or, if any
Applicant shall restrain the payment of the Credit by court order or any other
means, Applicants will jointly and severalty indemnify and save Bank harmless
from any and all loss, cost, damage, expense, suit, claim, cause of action,
judgement and attorneys' fees which may be suffered in incurred by Bank whether
caused in whole or in part by the negligence of Bank or any correspondent or
affiliate of Bank.

     13.  Applicants agree to procure promptly any required import, export or
other licenses, consents or certifications for the import, export or shipping of
any and all property shipped under or pursuant to or in connection with the
Credit to comply with any and all foreign and domestic government regulations,
rules and executive orders in regard to the shipment of any and all such
property or the financing thereof; to furnish such certificates in that respect
as Bank may at any time(s) require; to keep the property covered by insurance
satisfactory to Bank insured by insurers acceptable to Bank; and to assign the
policies or certificates of insurance to Bank, or to make the loss or adjustment
if any, payable to Bank, at its option, and to furnish Bank, if demanded, with
evidence with acceptance by the insurers by such assignment. Applicants certify
that neither the shipment of the property nor the origin thereof is such as
would render shipment or the issuance of or payment on the Credit in violation
of the laws, regulations, rules or executive orders of the United States of
America or of any other country having jurisdiction thereof.

     14.  No delay on Bank's part in exercising any power of sale or any other
rights or options hereunder, and no notice or demand which may be given to or
made upon Applicants by Bank with respect to any power of sale or other right or
option hereunder, shall constitute a waiver thereof, or limit or impaired Bank's
right to take any action or to exercise any power of sale, or any other rights
or options hereunder, without notice or demand, or prejudice Bank's rights as
against Applicants in any respect Bank will not be deemed to have waived any of
its rights unless Bank shall have signed such waiver in writing.

     15. Applicants represent and warrant that each Applicant has the authority
and has obtained all approvals and consents necessary to enter into and perform
this Agreement, and that the entering into and performance of this Agreement
will not result in a breach of any of the terms and conditions of any agreement,
instrument, order or judgement under which any Applicant is a party or by which
any Applicant or its property may be bound or affected or under any charter
documents of any Applicant, and will not violate any provision of applicable
law. This Agreement is to remain in force and be applicable to all transactions
notwithstanding any change in the composition of any firm or firms, parties to
this Agreement, or users or beneficiaries of the Credit, whether such change
shall arise from the accession of one or more partners or from the death or
secession of any partner or partners or from the incorporation of any
partnership, or otherwise.

     16.  Applicants agree that at all times now and hereafter they will
indemnify and save Bank harmless from and against all suits, judgements,
liabilities, losses or damages to it arising in any manner, including negligence
on the part of the Bank, in connection with the Credit or this Agreement, unless
due to gross negligence or willful misconduct on the part of the Bank and from
and against all costs, charges and expenses, reasonable attorneys' fees and
those costs, charges and expenses incurred in connection with all legal
proceedings, whether groundless or otherwise, it being the purpose of this
Agreement to protect Bank fully in the premisers.

     17.  Applicants agree that no acceptance or payment of overdrafts or
irregular drafts or of draft with irregular documents attached shall, if
asserted to or approved by any Applicant orally or in writing, or if Bank in
good faith accepts an indemnity limited to the actual damage, if any, caused by
such irregularity or discrepancy, impair any rights which Bank may have under
this Agreement. In case of any variation between the documents called for by the
Credit or this agreement and the documents accepted by Bank or Bank's
correspondents, Applicants each shall be deemed conclusively to have waived any
right to object to such variation with respect to any action by Bank or Bank's
correspondents relating to such documents and to have ratified and approved such
action as having been taken on Applicants' directions, unless Applicants
immediately upon receipt of such documents (and prior to receipt thereof by any
beneficiary or user of the Credit) file objection with Bank in writing, or
unless Bank has been provided with an indemnity, as aforesaid, Applicants
acknowledge and agree that the information in the Application portion of this
Agreement (the "Application") may be transmitted to Bank and relied on by Bank
in issuing the Credit by any means acceptable to Bank, including without
invitation, SWIFT, electronic mail, telex, twx, telephone, telecopy or telefax.
Applicants, Member and Correspondent (both hereinafter defined) agree to hold
Bank harmless from and against all claims, expenses, costs, liabilities,
attorneys' fees, suits, judgements, and causes of action arising out of any
discrepancy between the information in this Agreement, including without
limitation, the Application, and that transmitted to, or received by Bank.

     18.  This Agreement and the Credit are subject to and incorporate fully
herein (except as expressly modified herein or in the Credit) the Uniform
Customs and Practice for Documentary Credits (1993 Revision), International
Chamber of Commerce Publication No. 500, hereinafter referred to as "the
Uniformed Customs". This Agreement and the rights of Applicants and Bank
hereunder shall be subject to and governed by substantive laws of the State of
Texas, without reference to the rules regarding conflicts of laws, except when
the substantive laws of the State of Texas conflict with the Uniform Customs, in
which event the provisions of the Uniform Customs shall govern.

     19.  Issuance by Bank of the Credit applied for herein shall constitute
acceptance by Bank of this Agreement.

     20. If this Agreement contains the signature of a bank which is a
subsidiary of Chase Bank of Texas, N.A (hereinafter referred to as the
"Member") or of a correspondent bank of Bank (hereinafter referred to as the
"Correspondent"), then this Paragraph shall be applicable. In consideration of
Bank's issuing the Credit at the request of Correspondent or Member, as
applicable, Correspondent or Member as applicable, agrees that it is an
Applicant hereunder with respect to Bank, and it agrees to reimburse Bank on
demand and authorizes Bank, without demand or any notice whatsoever, to charge,
setoff against and otherwise exercise any rights Bank may have with respect to,
any monies now or hereafter on deposit with or otherwise to the credit of or
belonging to Correspondent or Member, as applicable, at or with Bank for any and
all Obligations hereunder, whether or not any demand has been made on Applicants
hereunder. However, unless agreed otherwise, or stated herein neither Member nor
Correspondent agrees to furnish any security for this Agreement or the Credit
other than the aforementioned monies. Upon Member's or Correspondent's payment
to Bank of all Obligations hereunder, Bank thereupon automatically, and without
further action on the part of any party, assigns and transfers its rights
hereunder to Correspondent or Member as applicable, who shall be fully
subrogated thereto, and Applicants agree that any right, claim or cause of
action which any of them may have hereunder or under the Credit shall be made
only against Correspondent or Member, as applicable, and Applicants agree,
regardless of whether Bank was negligent or not, to indemnify and hold Bank
harmless from and against any claims, costs, expenses, suits or causes of action
by Applicants or any beneficiary or user of the Credit. Applicants hereby agree
that Correspondent or Member, as applicable, shall also (in addition to Bank)
have the same rights, remedies, security interests and other liens as are stated
herein, to the same effect as if additional paragraphs were fully written herein
containing the same terms but substituting "Correspondent" or "Member" for
"Bank" throughout. All references to secured party, beneficiary or other similar
term contained in any deed of trust, security agreement, financing statement or
other document or instrument executed contemporaneously herewith or previously
executed by any of the Applicants for the benefit of Member or Correspondent
shall be deemed to include Bank as well as Member or Correspondent. All such
security agreements, financing statements, deeds of trust and other documents
and instruments are amended to the extent necessary in order that the
Obligations of Applicants hereunder are secured thereby and by the collateral
described therein on a pari passu basis with, and in addition to, any other
obligations secured thereby.

This written loan agreement represents the final agreement between the parties
and may not be contradicted by evidence of prior, contemporaneous, or subsequent
oral agreements of the parties.
There are no unwritten oral agreements between the parties.

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

     1.  Capitalized terms used in this Agreement to the extent not otherwise
defined herein shall have the same meanings as in the Credit Agreement.

     2.  If any Guarantor makes a payment in respect of the Guaranteed
Indebtedness, it shall have the rights of contribution and reimbursement set
forth below against the other Companies and shall be indemnified as set forth
below; provided that no Guarantor shall enforce its rights to any payment by
       --------
exercising its rights of contribution, reimbursement or indemnification unless
and until all the Guaranteed Indebtedness shall have been paid in full.

     3.  If any Guarantor makes a payment in respect of the Guaranteed
Indebtedness that is greater than its Pro Rata Percentage (hereinafter defined)
of the Guaranteed Indebtedness, calculated as of the date such payment is made,
the Guarantor making such payment shall have the right to receive from each of
the other Guarantors, and the other Guarantors jointly and severally agree to
pay to such Guarantor, when permitted by paragraph 2 hereof, an amount such that

Indebtedness shall be shared among the Guarantors pro rata in proportion to
their respective Pro Rata Percentages of the Guaranteed Indebtedness. The
Guarantors hereby jointly and severally indemnify each of the other Guarantors
and jointly and severally agree to hold each of them harmless from and against
any and all amounts which any such Guarantor shall ever be required to pay in
respect of the Guaranteed Indebtedness in excess of such Guarantor's respective
Pro Rata Percentage of the Guaranteed Indebtedness. Notwithstanding anything to
the contrary contained in this paragraph or in this Agreement, no liability or
obligation of any Guarantor that shall accrue pursuant to this Agreement shall
be paid nor shall it be deemed owed pursuant to this Agreement or any Loan
Documents unless and until all of the Guaranteed Indebtedness shall be paid in

Guarantor, the percentage derived by dividing (a) the amount by which the fair
saleable value of its assets on the Date of Determination (hereinafter defined)
exceeds its liabilities (without giving effect to its Guaranty) (such excess for
each Guarantor, its "Net Worth"), by (b) the Net Worth of all of the Guarantors.

                                  LITIGATION



     During the period from May 1999 through June 1999, five purported class
action lawsuits were filed in the United States District Court for the Southern
District of Florida, styled as follows: (1) Elfie Echavarri v. CellStar
Corporation, Alan H. Goldfield, Richard M. Gozia, and Mark Q. Huggins; (2) Mark
Krug v. CellStar Corporation, Alan H. Goldfield, Richard M. Gozia and Mark Q.
Huggins; (3) Jewell Wright v. CellStar Corporation, Alan H. Goldfield, Richard
M. Gozia and Mark Q. Huggins; (4) Theodore Weiss v. CellStar Corporation, Alan
H. Goldfield, Richard M. Gozia and Mark Q. Huggins; (5) Tony LaBella v. CellStar
Corporation, Alan H. Goldfield, Richard M. Gozia and Mark Q. Huggins. Each of
the above lawsuits seeks certification as a class action to represent those
persons who purchased the publicly traded securities of the Company during the
period from March 19, 1998 to September 21, 1998. Each of these lawsuits allege
that the Company issued a series of materially false and misleading statements
concerning the Company's results of operations and the Company's investment in
Topp Telecom, Inc. ("Topp"), resulting in violations of Sections 10(b) and 20(a)
of the Securities Exchange Act of 1934, as amended, and Rule 10(b)(5)
promulgated thereunder. The Company believes that it has complied with all
reporting requirements with respect to its results of operations and investment
in Topp and that it has meritorious defenses to these allegations and intends to
vigorously defend these actions.

     On August 3, 1998, the Company announced that the Securities and Exchange
Commission is conducting an investigation of the Company relating to its
compliance with federal securities law. The Company believes that it has fully
complied with all securities laws and regulations and is cooperating with the
Commission staff in their investigation.

     The Company is also a party to various other claims, legal actions and
complaints arising in the ordinary course of business. Management believes that
the disposition of these other matters will not have a material adverse effect
on the consolidated financial condition or results of operations of the Company.

          been duly executed and delivered by CellStar Telecom and constitutes
          the valid and binding obligation of CellStar Telecom enforceable in
          accordance with its terms, subject to bankruptcy, insolvency,
          moratorium, reorganization, and other laws affecting creditors' rights
          generally and to limitations in the availability of equitable
          remedies. The execution of and performance of the transactions
          contemplated by this Agreement and compliance with their provisions by
          CellStar Telecom will not (i) conflict with or result in any breach of
          any of the terms, conditions or provisions of, or constitute a default
          under, or require a consent or waiver under any indenture, lease,
          agreement or other instrument to which CellStar Telecom is a party or
          by which it or any of its properties are bound (other than such

<PAGE>

          transactions contemplated hereunder.

     (f)  Investment Representations Regarding the Shares. Neither CellStar

representation or warranty as to the financial condition, results of operations,

     (a)  Good Standing. The Purchaser is a company, duly organized, validly

          Purchaser has all requisite power and authority to own, lease and
          operate its properties and to carry on its business as now being
          conducted.

     (b)  Authority. The Purchaser has full right and power to execute,

          performance of the transactions contemplated by this Agreement and
          compliance with their provisions by the Purchaser will not (i)
          conflict with or result in any breach of any of the terms, conditions
          or provisions of, or constitute a default under, or require a consent
          or waiver under any indenture, lease, agreement or other instrument to
          which the Purchaser is a party or by which it or any of its properties
          are bound (other than such consents as are to be obtained prior to or
          upon the consummation of the transactions contemplated hereby), or
          (ii) require any consent, approval or authorization of, or declaration
          or filing with, any governmental authority (other

                                       3
<PAGE>

          than such consents, approvals, authorizations or filings as are to be
          obtained prior to the consummation of the transactions contemplated
          hereby).

     (c)  Investment Representation regarding the Shares. The Purchaser
          ----------------------------------------------
          acknowledges that the Shares have not been registered under the
          Securities Act, and may not be reoffered or resold, except pursuant to
          an exemption from the registration requirements of the Securities Act.
          The Purchaser is acquiring the Shares for investment purposes only and
          not with a view to, or for resale in connection with, any distribution
          thereof in violation of applicable law. The Purchaser understands that
          no liquid market exists for the Shares and that it is financially
          capable of bearing the potential risks associated with holding the
          Shares for an indefinite period of time. The Purchaser has not relied
          upon any representation, warranty or statement (other than the
          representations, warranties and statements contained in Section 3
          hereof) made by, nor upon any analysis of, CellStar Telecom in
          connection with its purchase of the Shares, and has made its own
          investment analysis and decision to purchase the Shares based upon
          such information as it has deemed appropriate. The Purchaser has the
          financial sophistication, knowledge and experience in financial
          matters, and access to the information, necessary to make an informed
          investment decision with respect to its proposed purchase of the
          Shares.

     (d)  No Brokers. The Purchaser has not made any agreement or taken any
          ----------
          action which might cause any person or entity to become entitled to a
          broker's fee or commission as a result of the transactions
          contemplated hereunder.

Other than as expressly set forth in this Section 4, the Purchaser makes no
representation or warranty whatsoever, and, specifically, makes no
representation or warranty as to the financial condition, results of operations,
cash flows, business, properties, prospects or creditworthiness of, or any other
circumstance in connection with Topp Telecom.

     5.   Covenant of CellStar Telecom. CellStar Telecom acknowledges on behalf
          ----------------------------

Telecom shall provide Topp Telecom with prompt written notice of such request or
requirement so that Topp Telecom may seek a protective order or such appropriate
remedy and/or waive compliance with this covenant. Notwithstanding the
foregoing, CellStar Telecom or any of its affiliates may disclose Confidential
Information: (i) to its attorneys, accountants and professional consultants who
need to know such information, or (ii) as CellStar Telecom or any of its
affiliates deems appropriate in connection with the pending putative class
actions currently filed or threatened, against CellStar Telecom or any of its

from the events and circumstances allegedly giving rise to said putative class

May 31, 1999


CellStar, Ltd.
National Auto Center, Inc.
1730 Briercroft Court
Carrollton, TX  75006

Ladies and Gentlemen:

     In conjunction with the May 31, 1999 Amendment to the Master Agreement for
the Purchase of Products and Inventory Maintenance, Assembly and Fulfillment
Services between Pacific Bell Mobile Services ("PBMS") and CellStar, Ltd.
("CellStar") dated September 20, 1996 (the "IAF Agreement"; capitalized terms
used herein and not otherwise defined shall have the meanings ascribed to them
in the IAF Agreement), PBMS agrees to purchase certain assets as of May 31, 1999
from CellStar and National Auto Center, Inc. ("NAC").  The basis for the
purchase price for the assets is described below and on Schedule A.   As of  May
21, 1999, the estimate of the purchase price is ** ****** ******** *** *******
********** ******** ***** ******* *********** *** ******** ******* ($******)
as set forth on Schedule A attached hereto and is subject to adjustment as
described below. Upon the approval by both PBMS and CellStar of the Amendment to
the IAF Agreement, PBMS shall pay the aggregate amount set forth below and
reflected on Schedule A hereto as an initial payment (the "Initial Payment").
The Initial Payment will be transferred, by wire transfer of immediately
available funds to the same CellStar account used in the weekly wire transfer
under the IAF Agreement, within seven (7) days following receipt by PBMS of a
fully executed copy of this letter agreement and a consent from CellStar's bank.
The assets to be purchased by PBMS as of May 31, 1999 and the calculation of the
Initial Payment are as set forth in Paragraphs 1-5 below.

     1.  Net Accounts Receivable:  The accounts receivable of CellStar under the
IAF Agreement as of May 21, 1999 will be the basis for the Initial Payment.
PBMS will transfer to CellStar XX% of the net balance for those Customer
accounts which have not been determined to be uncollectable due to Traditional
Credit Risk.  By June 15, 1999, CellStar will submit an aging of the accounts
receivable as of May 31, 1999 and recalculate the Net Accounts Receivable and
the Net Accounts Receivable Hold Back.  PBMS will review this calculation and
shall either pay or offset the difference, as appropriate, on the weekly wire
transfer under the IAF Agreement within seven (7) days following receipt by
CellStar of the Initial Payment.  Adjustments to the May 31, 1999, balance may
be made subsequent to June 15, 1999, in accordance with Section 4 of the IAF
Agreement as amended.

     2.  Dedicated Inventory in PBMS Branch Plants:  PBMS will purchase the
handsets, kits and individual components required to build the existing handsets
into kits and dry goods inventories equal to existing purchase orders for
handset kits from Product Vendors under the IAF Agreement ("Dedicated Inventory
Purchase Calculation") as of May 31, 1999.  All other inventory will remain the
property of CellStar or NAC, as the case may be, and be moved out of PBMS Branch
Plants by June 30, 1999. For purposes of the foregoing, PBMS and CellStar agree
to estimate the inventories on hand as of May 31, 1999 by using the inventories
on hand at the opening for business on May 24, 1999, as reported in the PBMS
Branch Plants.  CellStar will review the PBMS Branch Plant inventories as of May
31, 1999, and apply the Dedicated Inventory Purchase Calculation.  The
difference between the Net Inventory Purchased and the Dedicated Inventory
Purchase Calculation will be reconciled by the parties no later than July 31,
1999 and the difference will either be paid or offset, as appropriate, on the
next weekly wire transfer under the IAF Agreement.

     3.  Deduction for deposit payments: The Initial Payment will be net of the
amount of ****** ******** ****** *** ******** *** ******* ************ ***
******** ******* ($******) which represents the aggregate amount of deposit
payments previously paid by PBMS to CellStar with respect to the inventory
described in Paragraph 2 above under the IAF Agreement.

     4.  Deduction for Outstanding Product Supplier Accounts Payable:  The
Initial Payment will be net of the outstanding Product Supplier accounts payable
under the IAF Agreement for Product received as of May 21, 1999, into a PBMS
Branch Plant and for which PBMS approved the CellStar Order.  Product Supplier
accounts payable will be calculated as (a) Supplier invoices vouchered in
CellStar's accounts payable system and (b) a listing of items received but not
vouchered into CellStar's accounts payable system.  Invoices which are in
neither listing, but which have not been identified at this time will not
increase the Net Inventory Purchased calculation. The Product Supplier invoice
listing will indicate the CellStar Purchase Order number, the item identifier,
the actual price invoiced by the vendor and the invoice total.  Each invoice
will be reconciled to a product receipt in a PBMS Branch Plant and a PBMS-
approved CellStar Order.  The latter listing will indicate the CellStar Purchase
Order number, the item identifier and the Standard Cost of the item received.
Each item will be reconciled to a product receipt in a PBMS Branch Plant and a
PBMS-approved CellStar Order.  The amount of the deduction pursuant to this
Paragraph 4 will be verified as of July 31, 1999 to ensure that only Dedicated
Inventory purchases under PBMS-approved CellStar Orders are included.  PBMS and
CellStar recognize that there may be Purchase Price Variances recognized in
prior periods for which offsetting entries will be recorded subsequent to
purchase and that these amounts will adjust the amount owed by PBMS to CellStar
under the Net Inventory Purchased calculation in those subsequent months.

     5.  The parties hereby acknowledge that the calculations used to determine
the Initial Payment are estimates and agree that the Initial Payment shall be
reduced by the amount of *** ******* **** ******* ******** *** ******** ($*****)
which shall be reserved for the purposes of reconciling the estimates used in
calculating the Initial Payment and the final calculations to be determined by
the parties. Such reserved amount shall be held by PBMS and remitted to the
appropriate party immediately after the final determination of the aggregate
value of the assets purchased hereunder as of May 31, 1999, such determination
to be made within ninety (90) days following receipt by CellStar of the Initial
Payment.

     6.  The attached Schedule A summarizes the calculation of the estimate of
total consideration due to CellStar and the Initial Payment.

     7.  Notwithstanding anything to the contrary in this letter agreement, PBMS
agrees that it will remain liable to CellStar for the amounts deducted from the
Initial Payment in accordance with Paragraph 4 above pursuant to the terms of
the IAF Agreement, as amended.

     8.  PBMS hereby acknowledges that after the consummation of the purchase of
inventory contemplated by Paragraph 2 above CellStar may continue to own
inventory that may have been purchased by CellStar pursuant to PBMS forecasts
under the IAF Agreement.  With respect to such inventory, CellStar hereby
affirms its position as expressed in the correspondence from Mr. Dick Gozia on
February 16, 1999 to Mr. Bob Shaner.  PBMS hereby reaffirms its position as
expressed in the correspondence from Mr. Bob Shaner to Mr. Dick Gozia on
February 16, 1999.

                        credit line administration shall include making
                        recommendations to PBMS in establishing and maintaining
                        credit lines for Customers; setting credit lines in
                        accordance with CellStar's recommendations unless PBMS
                        instructs otherwise; monitoring Customer adherence to
                        credit lines; managing accounts receivable to obtain the
                        timely remittance of payments within established terms;
                        and placing Customers on credit hold for delinquency,
                        orders placed in excess of credit limit, or failure to
                        remit payments on time with good funds. CellStar will
                        not write-off any accounts receivable without prior
                        written approval of PBMS. Exceptions to CellStar's
                        credit administration procedures will not be made
                        without prior approval by PBMS' Chief Financial Officer
                        or designee and PBMS assumes responsibility for Customer
                        credit risk with respect to such approved exceptions. In
                        the event that CellStar is unable to collect the amounts
                        due from a Customer due to Traditional Credit Risk
                        exceptions to credit lines approved by the PBMS CFO or
                        designee, then PBMS will hold CellStar harmless for the
                        amounts unpaid in excess of the credit line established
                        by CellStar, unless other arrangements are agreed to in
                        writing by PBMS and CellStar. Customer balances
                        determined to be uncollectable will be excluded from the
                        computation of any Hold Back Amount under this
                        Agreement. CellStar assumes responsibility for all other
                        Traditional Credit Risk subject to a cap of the Net
                        Accounts Receivable Hold Back. PBMS is not responsible
                        for CellStar's costs to collect amounts owed by
                        Retailers, under this subsection, unless agreed to in
                        writing by PBMS' Chief Financial Officer or designee,
                        prior to those costs being incurred.
                    g.  PBMS shall be responsible for Customer charges or
                        deductions for allowances and other debits unrelated to
                        Traditional Credit Risk, provided that CellStar provides
                        PBMS with the applicable Proof of Delivery and timely
                        notifies PMBS of such debits as described in Section
                        4.2.3 (i); and provided further that nothing herein
                        shall be deemed to relieve CellStar of its
                        responsibility to fulfill Orders in accordance with
                        Specifications (e.g. CellStar's responsibilities with
                        respect to Order accuracy and shipment in accordance
                        with shipping instructions) and Fulfillment and kitting
                        accuracy (e.g. labeling, contents per Bill of Material).
                        If PBMS in good faith believes that any Customer
                        deduction for allowances, etc. are the result of
                        CellStar's failure to perform as described herein (based
                        on CellStar's receipt from PBMS of a (i) Performance
                        Notification Form, in the form attached as Exhibit

                        G within two (2) business days of the Retailer's receipt
                        (or non-receipt, if applicable) of the applicable
                        shipment, or (ii) electronic or facsimile notification
                        of the dispute within two (2) business day of the
                        Retailer's receipt (or non-receipt, if applicable) of
                        the applicable shipment, in the case of discrepancies,
                        then PBMS will notify and present the issue to CellStar
                        for resolution as set forth in Section 4.2.3 (j) below,
                        including correcting the Customers account and PBMS'
                        inventory, as applicable. PBMS and CellStar recognize
                        that some discrepancies may not be reasonably detected
                        within the time guidelines established above, including
                        labeling accuracy of master cartons and kits, and
                        contents of master cartons and kits. In these instances,
                        the notification guidelines above apply to the date of
                        discovery of the error by the Customer.
                    h.  CellStar shall provide all Fulfillment Services with
                        respect to Customer Orders.
                    i.  CellStar will notify PBMS (via a copy of the Retailer's
                        check) within ten (10) business days of deposit in its
                        bank account, of any deduction by a Retailer for any
                        reason, including returned goods, as set forth in
                        Section 4.2.4 (d) below. CellStar will notify PBMS of
                        any differences between the quantity and dollar amount
                        of goods returned by a Retailer and amount deducted by
                        that Retailer for such return in accordance with the
                        requirements of subsection (j) below. Such notice of
                        Retailer deductions shall be via the following reports:
                        RMA Customer Reconciliation Report and Retailer
                        Discrepancy Report, which are provided monthly to PBMS.
                    j.  If CellStar believes that it cannot collect an amount
                        due to PBMS for an amount deducted by a Retailer under
                        this section, then CellStar shall notify PBMS in writing
                        of the amount owed as stated in Section 4.2.4 (d) or
                        Section 4.2.3 (g) above. PBMS has ten (10) business days
                        from the date of notification by CellStar to dispute the
                        amount in accordance with the requirements of subsection
                        (k) below. If PBMS does dispute the amount notified by
                        CellStar within ten (10) business days and CellStar does
                        not dispute PBMS' notification with in the ten (10)
                        business days, PBMS will omit payment of the amount from
                        future electronic wire transfer payments to CellStar. If
                        PBMS and CellStar are unable to agree on the amounts
                        owed, the provisions of Section 49 will apply.
                    k.  If PBMS believes, based on a completed Performance
                        Notification Form provided to CellStar in accordance
                        with subsection (g) above, that CellStar owes PBMS for
                        an amount deducted by a Retailer under this section,
                        then PBMS shall provide CellStar with written
                        notification of the dispute (including a copy of the
                        applicable Performance Notification Form), detailing the
                        facts surrounding the non-performance and

                        CellStar shall have ten (10) business days from the date
                        of notification by PBMS to dispute the claim of non-

                        CellStar's notification within ten (10) business days
                        from the date of CellStar's notification, PBMS will
                        invoice CellStar for the disputed amount or will deduct
                        the disputed amount from future electronic wire transfer
                        payments to PBMS. If CellStar and PBMS are unable to
                        agree on amounts owed, the provisions of Section 49 will
                        apply.

                        excess of 30 days.
                    c.  CellStar will collect payments from Retailers on behalf
                        of PBMS.
                    d.  CellStar will perform payment reconciliation with
                        Retailers to assist PBMS in properly classifying
                        deductions and resolving disputes for unauthorized
                        Customer deductions from invoices and will provide
                        reconciliations to PBMS as described in Exhibit F. If
                        CellStar believes the difference cannot be collected by
                        CellStar, then CellStar will provide detail of
                        collection efforts with the Retailer, including the
                        individuals contacted, phone numbers and dates called,
                        and copies of any correspondence. Subject to PBMS's
                        rights under Section 4.2.3.g with respect to Performance
                        Notification Forms, PBMS will not deduct from amounts
                        owed CellStar for all Customer deductions not associated
                        with Traditional Credit Risk within ten (10) day time
                        period set forth in Section 4.2.3 (j) above whether
                        authorized or otherwise, if notified in accordance with
                        the procedure set forth in this Section 4.2.3 (i). If
                        either PBMS or CellStar disputes the amount billed by
                        the either party, the provisions of Section 4.2.3 (i)
                        and (j), respectively, will apply.
                    e.  Previous to the effective date of this agreement, if
                        PBMS reimbursed CellStar for a Customer deduction and
                        CellStar subsequently collects the deduction from the
                        Customer, either through direct cash payment or
                        application of outstanding credit issued to the
                        Customer, CellStar shall credit PBMS that amount as part

                        balance on behalf of PBMS as approved by PBMS, provided
                        that debit balances and deductions requested by PBMS's
                        CFO or designee will be offset prior to refund. At the

          4.2.6     Maintenance of Books and Records and Reports
                    a.  CellStar covenants and agrees to maintain books and

                        and shall make such existing books and records available
                        for PBMS' inspection upon five (5) business days' notice
                        from PBMS' Chief Financial Officer to CellStar's Account
                        Manager, including CPA auditors from a major accounting
                        firm hired by or engaged by PBMS, by and through
                        CellStar's representatives and agents, during regular
                        business hours on any business day. All other books and
                        records required to meet CellStar requirements with

                        reports described in Exhibit F Additional reports

                    c.  CellStar will make reasonable efforts to ensure that
                        data provided in the reports in Exhibit F and all
                        requests for payment for Services and Product shipped
                        under Orders are correct. If review and inspection of
                        the data by PBMS proves that the quantities shown or
                        dollar amounts provided in the informational reports
                        does not meet the standards set forth on Exhibit F, PBMS

                        is resolved to mutual satisfaction of both parties. If
                        review and inspection of data supporting an invoice
                        payment submitted to PBMS by CellStar proves that the
                        standards set forth on Exhibit F are not satisfied, PBMS
                        will withhold the disputed amount until the discrepancy
                        is resolved to mutual satisfaction of both parties. If
                        PBMS and CellStar are unable to agree on the amounts
                        owed, the provisions of Section 49 will apply.
                    d.  CellStar may provide to PBMS access via the Internet to
                        a CellStar managed website (the "Customer Access") to
                        retrieve the reports set forth in Exhibit F. Such access
                        shall be subject to applicable restrictions under
                        CellStar's license arrangements with software providers.

                        an adequate link to the Internet and for providing a
                        stable, adequate desktop computer environment. CellStar
                        agrees to support PBMS's browser software, provided that
                        PBMS uses Microsoft or Netscape browser software.
                    f.  PBMS agrees that is will appoint a site administrator to
                        serve as an interface point for any computers/systems
                        issues and that CellStar is not responsible for training
                        that individual. PBMS agrees that such individual will
                        be skilled in using the web browser software and EDI
                        communication standards for those portions of such
                        software in use from time to time under the agreement.
                        PBMS's site administrator will be given ability to set-
                        up user access, including passwords and levels of access
                        to the website. PBMS hereby assumes all risks involving
                        a breach of confidentiality hereunder by PBMS, its
                        employees or any of its other agents or representatives;
                        provided that the foregoing shall not apply with respect
                        to any individual to whom CellStar has authorized access
                        to the Customer Access, but who has not been granted
                        such access by PBMS. CellStar and PBMS will grant access
                        permission only to those individuals specifically
                        authorized in writing by PBMS Chief Financial Officer.
                        On two (2) business days notice demand, CellStar's
                        Account Manager will provide to PBMS, a listing of all
                        individuals (both CellStar and PBMS) authorized by
                        CellStar to access the PBMS information. CellStar's
                        Account Manager will modify access privileges of the
                        site administrator within 4 hours of receipt of a
                        written request by PBMS'sChief Financial Officer or
                        designee to terminate access for the site administrator.

                    g.  PBMS will notify CellStar within two (2) business day of
                        PBMS's recognition of any issues with service involving
                        the Customer Access.
                    h.  CellStar will implement a disaster recovery plan for its

                        complete fulfillment of affected unshipped Orders, and
                        offsite storage of PBMS data which would result in loss
                        of no more than two (2) business days of invoicing,
                        assembly and product testing activity. CellStar will

                        effective date of the Amended Agreement. Noncompliance
                        with the first sentence of this section constitutes a
                        material default in this Agreement and PBMS may cancel
                        this Agreement immediately, notwithstanding the fifteen
                        (15) day period in Section 24.a.
                    i.  PBMS shall acquire no license, ownership or other right
                        to the Customer Access or any other software or

                        respect thereof and that all such rights are, and shall
                        remain, vested in CellStar.

                        through its processing  system.
                    b.  Retailers and other Customers must contact PBMS and
                        receive a Return Material Authorization ("RMA") for each
                        Product return. For returns received with a proper RMA,
                        CellStar will credit the Customer on behalf of PBMS for
                        100% of the price authorized to be credited under the
                        applicable RMA. CellStar may refuse any return shipment
                        (i) which does not have a RMA number issued by PBMS or
                        (ii) with respect to which the RMA is not clearly
                        visible on the outside of the box or shipping carton.
                        PBMS will make reasonable commercial efforts to
                        encourage Retailers to return RMA's on separate
                        shipments. PBMS will cross-reference the Customer return
                        number to the PBMS-assigned RMA number. CellStar will
                        complete receiving audit processes as described in
                        Exhibit B on any return shipment with a RMA number
                        within the performance guidelines set forth in Exhibit
                        H, but in no case longer than five (5) business days of
                        CellStar's receipt of the returned Product. CellStar's
                        return processing shall include but not be limited to
                        insuring that the number of Product kits returned
                        matches the amount specified in the RMA. If the amount
                        of Product kits returned does not match the RMA,
                        CellStar shall notify PBMS within the reporting
                        guidelines set forth in Exhibit F, but in no case longer
                        than five (5) business days of CellStar's receipt of the
                        returned Products. With respect to any returns, CellStar
                        will issue a report to PBMS which lists, by RMA, the
                        quantities and Standard Cost for all non-reusable
                        collateral material, any missing Components and any non-
                        reusable items. An example of this report is included in
                        Exhibit F.
                    c.  PBMS will be responsible for setting the appropriate
                        quality standards for all inventory stock items in the
                        inventory master file. CellStar will determine the
                        classifications of Products based upon PBMS return
                        procedures. See Exhibit I, Classification of Product.
                        CellStar shall not be responsible for quality of
                        returned

                        products, if such products have been process in
                        a timely basis in accordance with Exhibits H and I.
                     d. PBMS is responsible for filing claims for freight losses
                        with its insurance carrier. CellStar will notify PBMS on
                        the same day it is notified by a Customer of any
                        potential loss or damage of product. Upon PBMS' request,
                        CellStar will provide to PBMS the information required
                        to submit a claim to PBMS's insurance carrier.
                    e.  All Customer returns and Product Supplier warranty
                        procedures for the Products shall be in accordance with
                        Product Supplier guidelines or instructions from PBMS.
                    f.  CellStar's returns audit, sort and breakdown, testing,
                        and refurbishment guidelines are set forth in Exhibit H.
                        CellStar's compensation for this performance is included
                        in the per-item returns processing prices set forth in
                        Exhibit B.

          4.2.9     Use of Fictitious Business Name
                    a.  The parties understand and agree that CellStar will, for
                        certain purposes, need to use the name "Pacific Bell
                        Mobile Services Fulfillment" or such other substantially
                        similar name as CellStar is able to register as an
                        assumed name in the State of Texas and Dallas County,
                        Texas, and in the State of California and San Bernardino
                        County, California (the "Name"). PBMS hereby authorizes
                        CellStar to use the Name for the following purposes: (i)
                        receipt and acceptance of payment from Customers
                        (including, without limitation, via lock-box wire
                        transfer or check), (ii) inclusion in shipping
                        collateral provided to Customers, (iii) invoicing of
                        Customers and provision of Customer statements, (iv)
                        written and oral correspondence with Customers, (v) such
                        other purposes as are authorized in writing by PBMS and
                        (vi) collection activities; provided that any use of the
                        Name by CellStar shall be in accordance with the
                        guidelines provided by PBMS entitled "Four Basic Rules",
                        incorporated by reference into this Agreement. PBMS
                        further authorizes CellStar to register the Name with
                        the Secretary of State of the State of Texas and in
                        Dallas County, Texas and with the Secretary of State of
                        the State of California and in San Bernardino County,
                        California. CellStar's right to use the Name is a
                        nonexclusive right and PBMS shall retain all ownership
                        and intellectual property rights in the Name. Except as
                        provided herein, CellStar shall not use the Name in any
                        advertising or publicity matter without PBMS' prior
                        written consent.

                    b.  Upon expiration, termination or cancellation of this
                        Agreement, CellStar may continue to use the Name only
                        during the period the Services are transitioned to PBMS
                        or its authorized

                        contractor and for the purpose of receiving or
                        collecting remaining payments, if any, due CellStar or
                        PBMS from Customers in connection with the Agreement
                        (collectively, the "Collections Transition Period").
                        Upon the conclusion of the Collections Transition
                        Period, and upon PBMS' request, CellStar shall confirm
                        in writing that it has ceased all use of the Name and
                        cancelled and withdrawn all registrations of the Name.

     4.3  Compensation

          PBMS shall make payments to CellStar as set forth below, and as set
          forth in Exhibits B.

          4.3.1     Dedicated Inventory

                    a.  On a monthly basis, CellStar will invoice PBMS for all
                        Products received in a PBMS Branch Plant and purchased
                        pursuant to a CellStar Order per Section 4.1.1.
                        ("CellStar Receipts Invoice").
                    b.  On a weekly basis, PBMS will transfer cash to CellStar
                        for Product Supplier invoices corresponding to Products
                        received in a PBMS Branch plant and purchased pursuant
                        to each CellStar Order, and for which payment is due to
                        the Product Supplier in the next seven (7) days ("Vendor
                        Invoice Requests"). Vendor Invoice Requests will be
                        reconciled to CellStar Receipts Invoices and the
                        corresponding Purchase Price Variance reported to PBMS.
                    c.  On a monthly basis, the Net On-Hand in PBMS Branch
                        Plants will be reconciled as the previous month's Net
                        Inventory On-Hand, plus CellStar Receipts Invoices, less
                        net Product Invoices and Price Protection reported for
                        the month.. The difference between Net Inventory On-Hand
                        and the on-hand inventory per PBMS Branch Plant at
                        Standard Cost ("On-Hand Inventory") will be reconciled
                        by CellStar. Any unsupported differences will reduce or
                        increase the Net Inventory Purchased to an amount no
                        lesser than the On-Hand Inventory.
                    d.  On a monthly basis, the outstanding amounts due to
                        Product Suppliers will be reconciled to the difference
                        between the Net Inventory Purchased and total Vendor
                        Invoice Requests.
                    e.  PBMS reserves the right to participate in CellStar's
                        quarterly physical inventory counts of PBMS Branch
                        Plants and to audit the reconciliation of the physical
                        count to the counts per the PBMS Branch Plant. PBMS may,
                        with no notice to CellStar, inspect and count all PBMS
                        inventory, provided that CellStar is not held
                        accountable for any delays in PBMS's product fulfillment
                        and kitting operations and/or that PBMS does not delay
                        other non-PBMS operations.

                    f.  PBMS will reimburse CellStar for the actual cost of
                        standard ground transportation from the Product Supplier
                        to CellStar. Exceptions to such standard ground
                        transportation must be approved by PBMS prior to
                        shipment by the Product Supplier.

          4.3.2  Credit for Customer Receivable
                    a.  On a weekly basis, the cash received from Customers will
                        be remitted to PBMS.
                    b.  On a monthly basis, CellStar will reconcile cash
                        received per the corresponding bank statements on behalf
                        of PBMS ("Cash Receipts") to the Net Customer Invoices
                        issued in the month plus the change in the Net Accounts
                        Receivable from the beginning of the month to the end of
                        the month ("Cash Rollforward"). Differences between the
                        Cash Rollforward and the Cash Receipts will be adjusted
                        by CellStar in the weekly wire following the
                        calculation, but no later than the 20th day of the month
                        after the basis month.
                    c.  An Accounts Receivable Hold-Back equal to **% of the Net
                        Accounts Receivable will be recalculated monthly. Any
                        difference in the Net Accounts Receivable Hold-Back as
                        of the end of the month will be paid to or deducted from
                        weekly wire transfers to CellStar within ten (10)
                        business days after the amount is reported by CellStar.
                        Upon termination of the Contract, the Net Accounts
                        Receivable Hold-Back will be repaid to CellStar ninety
                        (90) days after the Net Accounts Receivable with
                        supporting documentation has been provided to PBMS.

          4.3.3     Returns
                    See Exhibit B for the fees to be billed to PBMS for Products
                    returned by Customers.

          4.3.4     Purchase Price Variances and Price Protection
                    a.  For PBMS Branch Plants, CellStar shall operate on the
                        basis of a Standard Cost accounting system and shall
                        prepare all Product Invoices at Standard Cost as noted
                        in Section 4.2.4. CellStar shall change the Standard
                        Cost and Bill of Materials only upon the express request
                        of PBMS. Any change in Standard Cost will be documented
                        by PBMS and will include the new Bill of Material and
                        the change in standard cost for each Component within
                        the Bill of Material. CellStar will change the Standard
                        Cost in its system or establish a new Bill of Material
                        and related Standard Cost within five (5) business days
                        of receipt of a Bill of Material from PBMS.

                                                MASTER AGREEMENT NO. P/PS-960163


                    b.  Within eight (8) business days after the end of each
                        month (the "Month End"), CellStar shall report to PBMS
                        all Purchase Price Variances and Price Protection for
                        the account of PBMS. Such reports shall be effective as
                        of the close of that month, provided that CellStar shall
                        in no event be responsible for processing any invoices
                        or credits to PBMS related to the change in price of any
                        Components to the extent that CellStar has not changed
                        the Standard Cost in its system because it has not
                        received from PBMS the related Standard Cost change
                        within six (6) days prior to the end of the month.

     4.4  PBMS/Supplier Agreements
          a.        PBMS has included in PBMS/supplier agreements the right for
                    a third party distributor, such as CellStar, to execute
                    Orders under the PBMS/supplier agreements for the purchase
                    of PCS products. As necessary and as permitted by
                    nondisclosure agreements between PBMS and its suppliers,
                    PBMS agrees to provide CellStar a copy of the PBMS/supplier
                    agreements (or pertinent extracts) in order for CellStar to
                    order Dedicated Products only as PBMS may direct, and not
                    for the purpose of ordering products for any of CellStar's
                    other customers. CellStar agrees to keep the terms of the
                    supplier agreements strictly confidential and not to
                    disclose the terms of the PBMS/supplier agreements,
                    including pricing, to any third party, without PBMS' prior
                    written consent, unless that third party has a legitimate
                    need to know in the performance of services to CellStar, and
                    is covered by an appropriate confidentiality agreement prior
                    to accessing the Information. "Third parties" shall include
                    without limitation, any potential competitors of the Product
                    Suppliers, including competitors that are partners or third
                    parties holding any form of equity interest in CellStar.

          b.        In addition to the above (and subject to CellStar's rights
                    under Section 4.1.1. above regarding instances, if any, in
                    which CellStar (i) has notified PBMS that it cannot comply
                    with Supplier Terms prior to executing a CellStar Order
                    and/or (ii) has not received the Supplier Terms relating to
                    the PBMS/Supplier agreement which resulted in non-compliance
                    prior to PBMS's request that CellStar place a CellStar
                    Order), CellStar agrees to abide by Supplier Terms. CellStar
                    may not add any supplementary or conflicting terms to any
                    CellStar Order under a PBMS/supplier agreement without PBMS'
                    prior written consent. The right to receive any liquidated
                    damages, credits, market development funds, co-operative
                    advertising funds, promotional monies or other such payments
                    under a PBMS/supplier agreement shall belong exclusively to
                    PBMS whether or not CellStar executed a CellStar Order for
                    Dedicated Products in connection with the Product Supplier's
                    payment of liquidated damages, promotional monies or other
                    such payments. In the event the Product Supplier pays any
                    such liquidated damages, promotional monies or other such
                    payments to CellStar in connection with Dedicated Products,

                    CellStar shall immediately credit those funds to PBMS on the
                    next scheduled wire transfer without set-off, administrative
                    charge or deduction of any kind.

          c.        In connection with a CellStar Order for Dedicated Products
                    under a PBMS/supplier agreement for which PBMS was notified
                    of the due date on a timely basis under Section 4.3.1 and
                    payment was made by PBMS, if CellStar does not or, believes
                    it cannot, make full payment to any Product Supplier within
                    30 days following product delivery by the Product Supplier
                    under the applicable CellStar Order (other than due to
                    recovering discrepancies), CellStar's Account Manager shall
                    notify PBMS's Chief Financial Officer immediately and
                    provide information concerning the reason for the
                    nonpayment. CellStar will not be responsible for timely
                    payment in the event that PBMS does not pay the Product
                    supplier invoices to CellStar on a timely basis.
                    Notwithstanding the foregoing, CellStar agrees to make
                    reasonable best efforts to make payment to the Product
                    Suppliers when due and, subject to CellStar's right to cure
                    under Section 24, CellStar expressly acknowledges that
                    failure to do so shall result in a material breach by
                    CellStar of the terms of this Agreement, unless PBMS
                    expressly waives CellStar's breach in writing.

          d.        In the event that this Agreement expires or is terminated or
                    canceled, any credits, including default amounts remaining
                    in PBMS' account, shall be credited to PBMS in the next
                    scheduled wire transfer within thirty (30) days of such
                    expiration, termination or cancellation date. Additionally,
                    PBMS may set-off any PBMS payment due CellStar, by the
                    amount of credits due PBMS on the next scheduled wire
                    transfer.

Paragraph 6 of the Original Agreement shall be replaced in its entirety as
follows:

6.   PRICES
     Prices for services are set forth in Exhibit B. Price changes and prices
     for any Services set forth in Exhibit B shall be implemented only when
     agreed to in writing by both parties.

Paragraph 7 of the Original Agreement shall be replaced in its entirety as
follows:

7.   INVOICING AND PAYMENT
     a. Promptly after shipment of Products to the Customer, CellStar shall
        render a Product Invoice to PBMS for each such shipment. The invoice
        shall identify and separately show quantities and prices for each item
        shipped and for Services provided, any shipping charges to be borne by
        PBMS, applicable sales or use taxes, any discounts and total amount due.
        On a weekly basis, CellStar will provide PBMS with an electronic copy of
        the previous week's Customer Invoices

        sent by CellStar to a Retailer or other Customer for the corresponding
        items, and an electronic file of the corresponding SIM and/or IMEI. On a
        weekly basis CellStar will prepare a report reconciling all of Product
        Invoices to Customer Invoices. Unreconciled invoices will be withheld
        from wire transfers until reconciled as outlined in Section 4.2. .
     b. On a weekly basis, CellStar shall prepare a weekly wire transfer invoice
        summarizing amounts due to or from CellStar as outlined in Section 4.3.
     c. On a monthly basis, CellStar shall prepare a reconciliation of the Net
        Inventory On-Hand, Net Inventory Purchased, outstanding Product Supplier
        liabilities, Net Accounts Receivable and a detailed outline of all other
        items due to (from) PBMS. Refer to Exhibit F for an example of this
        reconciliation.
     d. PBMS shall promptly pay CellStar (without deduction) via electronic
        funds transfer the amount due within five (5) business days after
        receipt of the weekly wire transfer invoice. PBMS has the right to
        withhold an amount equal to the Product Invoice for shipments for which
        it has not received the corresponding Customer invoice and SIM/IMEI
        files on a timely basis. PBMS will pay CellStar for the shipment and
        deduct the corresponding amount due from the Customer in the next
        scheduled wire transfer five (5) business days after receipt of the
        missing items. Upon (5) business days notice, CellStar will provide to
        PBMS copies of the original invoice sent to Retailers, not to exceed 25
        invoices per request. PBMS will not take any deductions from CellStar
        invoicing to PBMS unless the provisions of 7.e, f and g below are
        followed. PBMS shall have the right to dispute the invoicing presented
        in accordance with the procedures set forth in subsection (f.) below.
     e. CellStar shall render a separate invoice to PBMS for Other Charges not
        already described in Sections 4.2.4, 4.2.5 and 7.a. Such invoice shall
        identify and separately state each charge. Documentation will include
        detail support of the item invoiced (e.g., applicable contract section.)
        PBMS shall contest any questionable charges within ten (10) business
        days of receipt of an invoice and supporting detail for Other Charges.
        If PBMS does not contest any of the Other Charges, PBMS shall pay
        CellStar the amount due via electronic funds transfer within ten (10)
        business days after receipt of the invoice unless CellStar cannot
        provide the justification provided for in subsection e below.
     f. If PBMS disputes any invoice rendered under subsections a or b above,
        PBMS' Chief Financial Officer shall notify CellStar's Accounting and
        Credit Departments of the detailed reasons for such dispute via
        electronic mail within ten (10) business days of receipt of the
        applicable invoice. CellStar will have ten (10) business days from
        receipt of PBMS' notice to provide PBMS with justification for the
        invoicing. If CellStar is unable to provide justification within such
        time provided that, if and when CellStar can prove that the invoicing is
        correct, PBMS shall reimburse CellStar for any deduction taken. Such
        reimbursement shall be due on the day of the next scheduled wire
        transfer.
     g. Notwithstanding the foregoing, PBMS reserves the right to make
        deductions from any outstanding invoice to the extent such deductions
        relate to errors of CellStar in performing Services as defined under
        this Agreement (e.g. errors in labeling Products, shipping instructions
        in Orders.). PBMS shall deduct the funds ten (10) days after written
        notice to CellStar. If CellStar disputes the deduction,

                                                MASTER AGREEMENT NO. P/PS-960163


        the parties shall negotiate in good faith to resolve the claim. If the
        parties do not agree, the provisions of Section 48 regarding
        notification and payment provisions will apply. However, if no funds are
        payable to CellStar for a period of 21 business days, and the amount
        owed by CellStar to PBMS is over $********, then CellStar shall remit
        payment to PBMS via electronic funds transfer. If no funds are payable
        to PBMS for a period of 21 business days, and the amount owed by PBMS to
        CellStar is over $*******, then PBMS shall remit payment to CellStar via
        electronic funds transfer.
     h. With respect to Section 7.a. and b. above, upon agreement by both
        parties, amounts due for transactions under such Sections may be
        consolidated for the purpose of the single transfer of funds. Nothing in
        this paragraph g. however, limits PBMS' right to make deductions,
        credits or set-off against payments due CellStar as set forth in various
        provisions in this Agreement.

Paragraph 8 of the Original Agreement shall be replaced in its entirety as
follows:

8.   SHIPPING AND PACKING
     a. CellStar shall ship all Orders to PBMS' Customers according to the
        specific shipping instructions for that Customer, unless PBMS specifies
        other instructions in the applicable Order or Amended Order, provided
        that CellStar shall have had a reasonable opportunity but in no event
        less than two (2) business days (with the exception of an individual
        Amended Order subject to Section 43.b) to (i) review the applicable
        Customer's standard shipping instructions prior to receipt of such
        Order, or (ii) make arrangements to accommodate any special instructions
        of such Customer. PBMS agrees to reimburse CellStar for actual freight
        charges. Whenever possible however, CellStar shall use the lowest priced
        shipping carrier (at contract carrier prices which are less than
        tariffed prices) that is capable of shipping the Products on time and
        meeting all other PBMS's requirements for shipping. In the event the
        Order or Amended Order contains other shipping instructions, then
        notwithstanding the section entitled "Order of Precedence" in this
        Agreement, the Order shall take precedence over the shipping
        instructions. All shipments shall originate in Dallas County Texas or
        San Bernardino County California unless CellStar obtains the prior
        written approval from PBMS' Chief Financial Officer or designee to ship
        from another point of origin.
     b. CellStar shall ship Products as specified in PBMS' Order or Amended
        Order to meet PBMS' specified shipment method and arrival date as
        described herein and in Section 43. CellStar shall be responsible for
        freight costs associated with any delivery that arrives late as a result
        of CellStar's error; provided that if PBMS requires a specific shipping
        carrier, CellStar shall not be responsible to the extent that PBMS's
        specified arrival date cannot be met via such shipping carrier. Provided
        that CellStar has received the applicable Order within the time
        specified in Section 43, if Products do not reach their destination by
        the specified arrival date, CellStar shall be responsible for any
        incremental freight cost to deliver the products within 24-hours of the
        date that CellStar becomes aware that it did not deliver the goods on
        the specified arrival date or the date CellStar is

        notified either by PBMS or the Customer, that the goods are not
        delivered on the specified arrival date, provided that CellStar shall
        not be responsible for non-performance of the shipping carriers.
     c. Marking and labeling ("Marking") of packages may vary depending on
        Product and Order type. Standard Markings shall include Markings which
        are or shall be required by applicable laws and regulations governing
        the environment and hazardous materials/wastes, Order number, container
        number, ship-to address, return address, date shipped and gross weight,
        where applicable.


Paragraph 9 of the Original Agreement shall be replaced in its entirety as
follows:

9.   TAXES
     a. PBMS shall reimburse CellStar the cost of all sales and use taxes and
        import and export duties, and other governmental fees to the extent
        related to PBMS' Orders not otherwise included in the invoice for the
        original shipment to PBMS Customers.
     b. CellStar agrees to pay, and to hold PBMS harmless from and against, any
        penalty, interest, additional tax or other charge that may be levied or
        assessed as a result of the delay or failure of CellStar for any reason
        to pay any tax or file any return or information required by law, rule
        or regulation or by this Agreement to be paid or filed by CellStar.
     c. If PBMS is exempt from payment of any applicable sales and/or use tax
        upon PBMS's Chief Financial Officer notifying CellStar's Account Manager
        of the basis for claiming such exemption CellStar agrees to take all
        legal and proper steps to sell the Products free of sales and/or use tax
        or to act as PBMS' agent in applying for any applicable rebate of tax.
        PBMS will, upon request furnish CellStar with any applicable tax
        exemption number.

Paragraph 10 of the Original Agreement shall be replaced in its entirety as
follows:

10.  RECORDS AND AUDITS
     CellStar shall maintain records of all matters which relate to CellStar's
     obligations hereunder in accordance with generally accepted accounting
     principles and practices, uniformly and consistently applied in a format
     that will permit audit.  Unless otherwise provided in this Agreement,
     CellStar shall retain such records for a period of four (4) years from the
     date of final payment under the Order to which such records relate.  To the
     extent that such records may be relevant in determining if CellStar is
     complying with its obligations under the applicable Order, PBMS and its
     authorized representatives shall, at any time, upon reasonable advance
     notice, no more than five (5) business days, from PBMS's Chief Financial
     Officer to CellStar's Account Manager, have access to such existing records
     for inspection and audit during normal business hours.  All records
     required to comply under this section will be made available, upon
     reasonable advance notice, not more than ten (10) business days, from
     PBMS's Chief Financial Officer to CellStar's Accounting Manager.

     be required under the laws, ordinances, and regulations of any governmental
     authority, with respect to CellStar's performance under this Agreement, is

        the performance of Services or any Order. In the event of such
        suspension, change or termination, PBMS shall pay to CellStar the
        reasonable cost of shipping incurred and kits build up to the date of
        said suspension, change or termination. PBMS shall not be responsible
        for any other costs of shipment or costs of Services performed prior to
        termination. To the extent that CellStar Orders cannot be cancelled by
        either CellStar or PBMS, PBMS will assume responsibility for open
        CellStar Orders specifically approved by PBMS in writing prior to being
        placed by CellStar.
     b. If PBMS directs a change or suspension in an Order, the parties shall
        agree to any adjustments in prices or dates necessitated thereby and
        shall execute a revised Order reflecting such adjustments.
     c. Subject to Section 40 below, CellStar may not, without PBMS' prior
        written consent, make any changes whatsoever with respect to the
        Products or Services specified in any Order hereunder.

     CellStar for such Services at the prices set forth in such Order and the
     parties shall execute a revised Order to reflect such partial termination
     or cancellation.  The right to cancel an Order shall also include the right
     to cancel any other affected Order.

Paragraph 42 of the Original Agreement shall be replaced in its entirety as
follows:

42.  MBE/WBE/DVBE CANCELLATION CLAUSE
     a.   CellStar agrees that falsification or misrepresentation of, or failure
          to report a disqualifying change in, the MBE/WBE/DVBE status of
          CellStar or any subcontractor utilized by CellStar; or CellStar's
          failure to comply in good faith with any MBE/WBE/DVBE utilization
          goals established by CellStar; or CellStar's failure to cooperate in
          any investigation conducted by Pacific Bell, or by Pacific Bell's
          agent, to determine CellStar's compliance with this section, will
          constitute a material breach of this Agreement. In the event of any
          such breach, Pacific Bell may, at its option, cancel ("Cancel") this
          Agreement upon 20 days notice. CellStar acknowledges and agrees that
          Pacific Bell's right to Cancel is absolute and unconditional, and
          Pacific Bell shall not be subject to liability, nor shall CellStar
          have any right to suit for damages as a result of such cancellation.
     b.   For purchases under this Agreement by Pacific Bell, Pacific Bell
          Directory, Pacific Bell Mobile Services, Pacific Bell Information
          Services, Pacific Bell Communications, and any other entity operating
          principally in California (collectively "California Affiliates"),
          Minority and Women Business Enterprises (MBEs/WBEs) are defined as
          businesses which satisfy the requirements of paragraph c. below and
          are certified as MBEs/WBEs by the California Public Utilities
          Commission Clearinghouse ("CPUC-certified").
     c.   For purchases under this Agreement by any entity that is not a
          California Affiliate, MBEs/WBEs are defined as businesses which
          satisfy the requirements of paragraph d. below and are either CPUC-
          certified or are certified as MBEs/WBEs by a certifying agency
          recognized by the purchasing entity.
     d.   MBEs/WBEs must be at least 51% owned by a minority individual or group
          or by one or more women (for publicly-held businesses, at least 51% of
          the stock must be owned by one or more of those individuals), and the
          MBEs/WBEs' management and daily business operations must be controlled
          by one or more of those individuals, and these individuals must be
          either U.S. citizens or legal aliens with permanent residence status.
          For the purpose of this definition, minority group members include
          male or female Asian Americans, Black Americans, Filipino Americans,
          Hispanic Americans, Native Americans (i.e., American Indians, Eskimos,
          Aleuts and Native Hawaiians), Polynesian Americans, and multi-ethnic
          (i.e., any combination of MBEs and WBEs where no one specific group
          has a 51% ownership and control of the business, but when aggregated,
          the ownership and control combination meets or exceeds the 51% rule).
          "Control" in this context means exercising the power to make policy
          decisions. "Operate" in this context means actively involved in the
          day-to-day management of the business and not merely acting as
          officers or directors.
     e.   For purchases under this Agreement by California Affiliates, Disabled
          Veteran Business Enterprises (DVBEs) are defined as business concerns
          that satisfy the requirements of paragraph e. below and are certified
          as DVBEs by the California State Office of Small and Minority Business
          (OSMB). The DVBE must be a resident of the State of California, and
          must satisfy the requirements of paragraph (g.) below.

     f.   For purchases under this Agreement by any entity that is not a
          California Affiliate, DVBEs are defined as any business concern that
          satisfies the requirements of paragraph g. below and is either a
          defined DVBE for purchases by California Affiliates, or is certified
          as a DVBE by a certifying agency recognized by the purchasing entity.
     g.   The DVBE must be (1) a sole proprietorship at least 51% owned by one
          or more disabled veterans; or (2) a publicly-owned business in which
          at least 51% of the stock is owned by one or more disabled veterans;
          or (3) a subsidiary which is wholly owned by a parent corporation, but
          only if at least 51% of the voting stock of the parent corporation is
          owned by one or more disabled veterans; or (4) a joint venture in
          which at least 51% of the joint venture's management and control and
          earnings are held by one or more disabled veterans. In each case, the
          management and control of the daily business operations must be by one
          or more disabled veterans. A disabled veteran is a veteran of the
          military, naval or air service of the United States with a service-
          connected disability. "Management and control" in this context means
          exercising the power to make policy decisions and actively involved in
          the day-to-day management of the business and not merely acting as
          officers or directors.

Paragraph 43 of the Original Agreement shall be replaced in its entirety as
follows:

43.  DELIVERY OF PRODUCTS AND PERFORMANCE OF SERVICES
     In addition to the shipping services described in Section 8.b the following
     applies to all Orders and Amended Orders:
     a.   Subject to Sections 4.2.1 and 4.2.4, all dates for shipment or
          delivery of Products and performance of Services are firm and time is
          of the essence. Shipment or delivery dates shall be specified in each
          Order or as amended by written communication only (including e-mail or
          fax).
          i.        Subject to Sections 4.2.1 and 4.2.4, in the event CellStar
                    fails to meet the scheduled delivery date and the Customer
                    cancels the Order, CellStar agrees to assume return shipping
                    costs for the canceled Products if the late delivery was due
                    to CellStar's error.
          ii.       Subject to Sections 4.2.1 and 4.2.4, in the event CellStar
                    fails to meet the scheduled delivery date set forth in the
                    applicable Orders amended but the Customer nonetheless
                    accepts the late shipment, CellStar shall, assume liability
                    for deductions taken by that Customer specifically related
                    to fees in connection with the late shipment if the late
                    shipment was due to CellStar's error and within CellStar's
                    reasonable control.
     b.   Orders received via EDI by 1pm local time will be shipped on the same
          day as the Order is received.  However, CellStar will not be obligated
          to ship more than 3,000 units by Federal Express or UPS and 5,000
          units by any other carrier.  Notwithstanding anything to the contrary
          herein , PBMS understands and agrees that CellStar shall not be
          responsible for same day shipping for quantities in excess of 1,500
          units per day unless CellStar receives the applicable Order by

          p.m., Pacific Standard Time for shipment from California on the
          shipment date.

Paragraph 46 of the Original Agreement shall be replaced in its entirety as
follows:

46.  RISK OF LOSS
     CellStar will be responsible for risk of physical loss of or damage to all
     inventories in their facilities.  CellStar will provide to PBMS sufficient
     detail to enable PBMS to obtain insurance coverage from the point of
     shipment.  CellStar will follow written procedures provided by PBMS and its
     insurance provider to enable PBMS to file claims with its insurance
     carrier.

Paragraph 48 is deleted in its entirety.


52.  ENTIRE AGREEMENT
     This Agreement, including all Orders, exhibits and subordinate documents
     attached to or referenced in this Agreement or any Orders and all
     proposals, descriptions, drawings, Specifications, marketing materials and

     agreement between PBMS and CellStar with respect to the subject matter.

                                   Exhibit H

Retail Returns Policy
Return Merchandise Authorization (RMA): All returns from retailers must be
approved in advance by PBMS. An RMA form is to be completed by the appropriate
Retailer sales manager or PBMS account executive and forwarded to PBMS Customer
Service in Pleasanton. The RMA must specify SKUs and quantities for all items
authorized for return. The RMA can remain open for a maximum duration of 45 days
from issuance and will be valid only for a single shipment to CellStar. Customer
Service personnel will assign a RMA authorization number to the document and
enter it into the order processing system. The transaction will be forwarded to
the customer with shipping instructions as authorization for return of
merchandise.

Criteria for Retail Returns:
1. The retailer requests a RMA # from PBMS.
2. PBMS issues a RMA #.
3. The retailer will return the product to CellStar in Carrollton, Texas.
4. All kits must be returned complete to CellStar.
         a)  Handset       d)  Travel Charger
         b)  Battery       e)  Car Lighter Adapter, if applicable
         c)  Antenna       f)  Leather case or other accessory, if applicable
5. All loose kits must be returned in a master carton.
6. All master cartons must have the Following:
         a)  RMA # clearly marked on the outside of every carton.
         b)  If there is more than  one master carton the cartons should be
             marked 1 of 3, 2 of 3, 3 of 3.
7. If a pallet is used to ship the kits the following is required:
         a)  Only master cartons are to be put on a pallet.
         b)  The height cannot exceed 5 ft tall
         c)  The pallet must be marked "Do Not Stack"
         d)  The pallet must be secured with a pallet cover, shrink wrap and
             security tape.
8. The freight carrier should be the same freight company that delivered the
   product.

Unauthorized Returns: In the event returned merchandise is delivered without
prior authorization, CellStar will contact PBMS Retail Customer Service to
resolve discrepancy for shipments with a packing slip but no RA number.
Shipments with no packing slip and no RMA may be refused delivery by CellStar
and returned to the carrier for disposition. Upon refusal, the distribution
center will notify the appropriate PBMS Customer Service personnel of an
attempted return so that the issue may be pursued with that customer. The
parties recognize that some refused shipments may be subsequently authorized for
return, however, the policy of refusing unauthorized shipment will be
continually enforced to prevent abuse of returns policy by customers. In cases
when delivery is not refused, the RMA will be resolved by PBMS Customer Service
and equipment accounted for in inventory.

Freight Charges: All merchandise is to be returned to the PBMS Fulfillment
Center in Carrollton, Texas and freight charges are to be prepaid by the
customer. Collect freight may be authorized by PBMS Customer Service or the
appropriate PBMS sales manager where the return is the result of a PBMS error or
other special circumstances exist. Unless the RMA specifically authorizes the
return of merchandise at PBMS expense, shipments returned "freight collect" will
be refused at the PBMS dock. If a retailer receives an incorrect shipment, the
retailer should contact PBMS Customer Service for resolution. The PBMS customer
service representative will utilize the shipping discrepancy form for
investigation by CellStar. If the shipment error was made by CellStar the return
shipment will be authorized by PBMS as freight collect and the retailer should
use the same shipper as the original shipment, if possible.

                                    Page 2

Customer Deductions for Unauthorized Returns: Deduction for unauthorized returns
will be pursued by CellStar for collection.  Failure of the customer to remit
funds for such deductions in a timely manner will impact the shipment of future
orders.

Customer Deductions for Missing or Damaged beyond Manufacturer Repair
Components: PBMS will pursue deductions for components missing and/or
physically noticeable as damaged beyond manufacturer repair upon inspection of
return kits.  Missing components such as batteries, travel chargers and other
accessories will be deducted from the total credits to the retailer.  If a
handset is found to be damaged beyond repair and was not physically noticed upon
original inspection by CellStar and is returned from vendor as such, then
CellStar will provide PBMS with this information.  This information will be
submitted with the RTV data as an exception on the RTV movement report from
CellStar.  PBMS will take appropriate action to these rectify these exceptions
with Retailers.

Performance Guidelines:
CellStar will validate all returns for RMA numbers and associated returns. If
any discrepancy exists CellStar will contact PBMS to resolve. All returns
received should be visually inspected for validation of number of complete kits,
and Bill of Materials to actual components received within one business day of
receipt. This information should be transmitted electronically to PBMS for
adjustments. Performance measurements include:

Process Measures:
 .   Turnaround time from receipt from retailer at shipping dock to RA and BOM
    validation and reporting within one business day from receipt.
 .   Classification and testing of A, B, C, D, E stock within one business day of
    receipt from retailer
 .   Movement to main warehouse or other point of distribution designated within
    one business day of Quality Assurance inspection
 .   Movement into and out of refurbishment within two business days from
    classification of C stock
 .   Request for Return Authorization to vendor for repair and credit within one
    business day of classification for maximum allowable shipments by vendor.
    The return to vendor log will include date shipped, order #, JDE number,
    quantity, SKU, date returned from vendor and standard costs.

Quality Measures:
Final Quality Assurance inspection is done for every 7 phones out of cartons of
50.  If 1 is found defective, CellStar inspects an additional 7 handsets.  If
another defective handset found, the complete carton is failed and returns to
the classification and testing processes.  Monthly reports with daily detail on
quality inspection results should be provided to Pacific Bell Mobile Services.

                                   Exhibit I

Classification of Handsets:

In QPBMS warehouse all products should be received as A Stock from-retail and
reclassified in a separate process before transferring out.

A Stock: 100% appearance, 100% functionality and less than 60 minutes of use
         This equipment should be returned to inventory with one business day of
         QC testing for redistribution. Any A stock component should be
         transferred to the main warehouse and used for kitting prior to
         purchasing additional components for kitting.

B Stock: 100% appearance, 100% functionality and greater than 60 minutes of use
         This equipment can be redeployed into markets for sale to end users and
         into the exchange group for replacements. Any returned Component should
         be transferred to the WPBMS Branch Plant for kitting if 100% in
         appearance.

C Stock: 100% functionality and Less than 100% appearance
         These phones may require cosmetic upgrade which may include buffing and
         lens replacements. Once they have been cosmetically upgraded, they can
         be moved to A or B Stock dependent on their minutes of use and may be
         sold as is.

D Stock: Less than 100% functionality (defective) and should be returned to
         vendor (RTV) for credit or repairs

E Stock: Less than 100% functionality (defective beyond manufacturer repair
         capability)

Classification of Accessories:
All accessories that are reclassified become the liability of PBMS upon shipment
to customers, once it is ascertained that the proper classification has been
made by CellStar. A sample of accessories (7 out of 50) will be quality tested
and results will be provided to PBMS. PBMS also has the right at any time to do
a physical inspection at the CellStar returns warehouse to validate that proper
classification is taking place.

and to be received by the Pledgor as a result of the Borrower, the Agent, the
Co-Agents and the Banks entering into the Credit Agreement and the Pledgor

expected to benefit the Pledgor directly and

time to time under the Credit Agreement will benefit Pledgor and the

and convenient to the conduct, promotion and attainment of the business of the

U.S.C. (S) 101 or applicable law) and will not be rendered insolvent by its
obligations hereunder. The foregoing representations are supported by the
Pledgor's internal projections and forecasts. The Pledgor has determined that
the execution and delivery of this Agreement is to its advantage and benefit,
taking into account all relevant facts and circumstances.

     and Pledgor's expense, at any time, or from time to time, all acts and
     things which the Agent deems necessary to protect, preserve, or realize

     This power of attorney is a power coupled with an interest and shall be
irrevocable.  The Agent shall be under no duty to exercise or withhold the
exercise of any of the rights, powers, privileges, and options expressly or
implicitly granted to the Agent in this Agreement, and shall not be liable for

     Section 4.3.   Dividends and Distributions.  Unless and until an Event of
                    ---------------------------

     Section 4.4.   Setoff; Property Held by Agents and the Banks.  If an Event
                    ---------------------------------------------

each Bank shall have the right to set off and apply against the Obligations, at
any time and without notice to Pledgor, any and all deposits (general or
special, time or demand, provisional or final) or other sums at any time
credited by or owing from the Agent, any Co-Agent or any Bank to Pledgor whether
or not the Obligations are then due.  As additional security for the
Obligations, Pledgor hereby grants the Agent, each Co-Agent and each Bank a
security interest in all money, instruments, and other property of Pledgor now
or hereafter held by the Agent, any Co-Agent or any Bank, including, without
limitation, property held in safekeeping.  In addition to the Agent's, any Co-
Agent's or any Bank's right of setoff and as further security for the

provisional or final) and other accounts of Pledgor now or hereafter on deposit
with or held by the Agent, any Co-Agent or any Bank and all other sums at any
time credited by or owing from the Agent, any Co-Agent or any Bank to Pledgor.

in addition to other rights and remedies (including, without limitation, other
rights of setoff) which the Agent, any Co-Agent or any Bank may have.

     Section 4.5.   Performance by Agent.  If Pledgor shall fail to perform any
                    --------------------
covenant or agreement contained in this Agreement, the Agent may perform or
attempt to perform such covenant or agreement on behalf of Pledgor.  In such
event, Pledgor shall, at the request of the Agent, promptly pay any amount
expended by the Agent in connection with such performance or attempted
performance to the Agent, together with interest thereon at the Default Rate
from and including the date of such expenditure to but excluding the date such

     Section 4.6.   Agent's Duty of Care.  Other than the exercise of reasonable
                    --------------------
care in the physical custody of the Collateral while held by the Agent
hereunder, the Agent shall have no responsibility for or obligation or duty with
respect to all or any part of the Collateral or any matter or proceeding arising
out of or relating thereto, including, without limitation, any obligation or
duty to collect any sums due in respect thereof or to protect or preserve any
rights against prior parties or any other rights pertaining thereto, it being
understood and agreed that Pledgor shall be responsible for preservation of all
rights in the Collateral.  Without limiting the generality of the foregoing, the
Agent shall be conclusively deemed to have exercised reasonable care in the
custody of the Collateral if the Agent takes such action, for purposes of
preserving rights in the Collateral, as Pledgor may reasonably request in
writing, but no failure or omission or delay by the Agent in complying with any
such request by Pledgor, and no refusal by the Agent to comply with any such
request by Pledgor, shall be deemed to be a failure to exercise reasonable care.

                                    -------

     Section 5.1.   Rights and Remedies.  If any Event of Default shall occur,
                    -------------------
the Agent shall have the following rights and remedies:

          (i)  In addition to all other rights and remedies granted to the Agent
     in this Agreement and in any other Loan Document or by applicable law, the
     Agent shall have all of the rights and remedies of a secured party under
     the UCC.  Without limiting the generality of the foregoing, the Agent may
     (A) without demand or notice to Pledgor, collect, receive, or take
     possession of the Collateral or any part thereof, (B) sell or otherwise
     dispose of the Collateral, or any part thereof, in one or more parcels at
     public or private sale or sales, at the Agent's offices or elsewhere, for
     cash, on credit, or for future delivery, and/or (C) bid and become a
     purchaser at any sale free of any right or equity of redemption in Pledgor,
     which right or equity is hereby expressly waived and released by Pledgor.
     Upon the request of the Agent, Pledgor shall assemble the Collateral and
     make it available to the Agent at any place designated by the Agent that is
     reasonably convenient to Pledgor and the Agent.  Pledgor agrees that the
     Agent shall not be obligated to give more than five days written notice of
     the time and place of any public sale or of the time after which any
     private sale may take place and that such notice shall constitute
     reasonable notice of such matters.  The Agent shall not be obligated to
     make any sale of the Collateral regardless of notice of sale having been
     given. The Agent may adjourn any public or private sale from time to time
     by announcement at the time and place fixed therefor, and such sale may,
     without further notice, be made at the time and place to which it was so
     adjourned.  Pledgor shall be liable for all expenses of retaking, holding,
     preparing for sale, or the like, and all attorneys' fees and other expenses
     incurred by the Agent in connection with the collection of the Obligations
     and the enforcement of the Agent's rights under this Agreement, all of
     which expenses and fees shall constitute additional Obligations secured by
     this Agreement.  The Agent may apply the Collateral

PLEDGE AGREEMENT - Page 10
[CellStar Telecom, Inc.]
<PAGE>

     against the Obligations in such order and manner as the Agent may elect in
     its sole discretion. Pledgor shall remain liable for any deficiency if the
     proceeds of any sale or disposition of the Collateral are insufficient to
     pay the Obligations. Pledgor waives all rights of marshalling in respect of
     the Collateral.

          (ii)  The Agent may cause any or all of the Collateral held by it to
     be transferred into the name of the Agent (if the Agent is not yet the
     registered owner of the Collateral) or the name or names of the Agent's
     nominee or nominees.

          (iii) The Agent may collect or receive all money or property at any
     time payable or receivable on account of or in exchange for any of the
     Collateral, but shall be under no obligation to do so.

          (iv)  The Agent shall have the right, but shall not be obligated to,
     exercise or cause to be exercised all voting, consensual, and other powers
     of ownership pertaining to the Collateral, and Pledgor shall deliver to the
     Agent, if requested by the Agent, irrevocable proxies with respect to the
     Collateral in form satisfactory to the Agent.

          (v)   The Agent may notify or require Pledgor to notify parties
     obligated under any accounts, instruments, contracts or agreements which
     are part of the Collateral to make payment directly to the Agent, and the
     Agent may take possession of all proceeds of any such instruments and
     contracts in Pledgor's possession.  Any such payments or distributions
     received by Pledgor after an Event of Default shall, until paid or
     delivered to the Agent, be held by Pledgor in trust as additional security
     for the Obligations.

          (vi)  Pledgor hereby acknowledges and confirms that the Agent may be
     unable to effect a public sale of any or all of the Collateral by reason of
     certain prohibitions contained in the Securities Act of 1933, as amended,
     and applicable state securities laws and may be compelled to resort to one
     or more private sales thereof to a restricted group of purchasers who will
     be obligated to agree, among other things, to acquire any shares of the
     Collateral for their own respective accounts for investment and not with a
     view to distribution or resale thereof.  Pledgor further acknowledges and
     confirms that any such private sale may result in prices or other terms
     less favorable to the seller than if such sale were a public sale and,
     notwithstanding such circumstances, agrees that any such private sale shall
     be deemed to have been made in a commercially reasonable manner, and the
     Agent shall be under no obligation to take any steps in order to permit the
     Collateral to be sold at a public sale.  The Agent shall be under no
     obligation to delay a sale of any of the Collateral for any period of time
     necessary to permit any issuer thereof to register such Collateral for
     public sale under the Securities Act of 1933, as amended, or under
     applicable state securities laws.

          (vii)  On any sale of the Collateral, the Agent is hereby authorized
     to comply with any limitation or restriction with which compliance is

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

     1.   Capitalized terms used in this Agreement to the extent not otherwise
defined herein shall have the same meanings as in the Credit Agreement.

     2.   If any Guarantor makes a payment in respect of the Guaranteed
Indebtedness, it shall have the rights of contribution and reimbursement set
forth below against the other Companies and shall be indemnified as set forth
below; provided that no Guarantor shall enforce its rights to any payment by
       --------
exercising its rights of contribution, reimbursement or indemnification unless
and until all the Guaranteed Indebtedness shall have been paid in full.

     3.   If any Guarantor makes a payment in respect of the Guaranteed
Indebtedness that is greater than its Pro Rata Percentage (hereinafter defined)
of the Guaranteed Indebtedness, calculated as of the date such payment is made,
the Guarantor making such payment shall have the right to receive from each of

Pro Rata Percentage of the Guaranteed Indebtedness. Notwithstanding anything to
the contrary contained in this paragraph or in this Agreement, no liability or
obligation of any Guarantor that shall accrue pursuant to this Agreement shall
be paid nor shall it be deemed owed pursuant to this Agreement or any Loan
Documents unless and until all of the Guaranteed Indebtedness shall be paid in
full.  As used herein, the term "Pro Rata Percentage" shall mean, for each

Guarantor, the percentage derived by dividing (a) the amount by which the fair
saleable value of its assets on the Date of Determination (hereinafter defined)
exceeds its liabilities (without giving effect to its Guaranty) (such excess for

permitted by paragraph 2 hereof, an amount equal to such payment.  The Borrower
             -----------
hereby indemnifies each of the Guarantors and agrees to hold each of them
harmless from and against any and all amounts which any such Guarantor shall
ever be required to pay in respect of the Guaranteed Indebtedness.
Notwithstanding anything to the contrary contained in this paragraph or in this
Agreement, no liability or obligation of the Borrower that shall accrue

     document of such party or of any agreement, judgment, injunction, order,
     decree or other instrument binding upon such party or result in the

     be due and payable, and is not insolvent (as that term is defined in 11
     U.S.C. (S) 101 or applicable law) and will not be rendered insolvent by its
     obligations hereunder, and the foregoing representation is supported by
     such Company's internal projections and forecasts.

     6.   No failure or delay by any Guarantor in exercising any right, power or
privilege hereunder shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege.  The rights and remedies herein
provided shall be cumulative and non-exclusive of any rights or remedies

                                   GUARANTY
                                   --------

for the benefit of each of the banks or lending institutions (each, a "Bank"
                                                                       ----
and, collectively, the "Banks") which is or may from time to time become a

permitted assignee thereof, and Chase Bank of Texas, National Association

                                                                   -----

     WHEREAS, Cellstar Corporation, a Delaware corporation (the "Borrower"), the

                                                                 ------
Agreement"); and
- ---------

     WHEREAS, the Credit Agreement requires each Guarantor to execute and
deliver this Guaranty.

     NOW, THEREFORE, for valuable consideration, the receipt and adequacy of
which are hereby acknowledged, the Guarantors hereby jointly and severally,
irrevocably and unconditionally guarantee to the Agent, the Co-Agents and the
Banks the full and prompt payment and performance of the Guaranteed Indebtedness
(hereinafter defined), this Guaranty being upon the following terms:

     1.   The term "Guaranteed Indebtedness", as used herein, means all of the
                    -----------------------
"Obligations", as defined in the Credit Agreement. The term "Guaranteed
                                                             ----------
Indebtedness" shall include any and all post-petition interest and expenses
- ------------
(including reasonable attorneys' fees) whether or not allowed under any
bankruptcy, insolvency, or other similar law.  All other capitalized terms used
and not otherwise defined herein shall have their respective meanings as set
forth in the Credit Agreement.

     2.   This instrument shall be an absolute, continuing, irrevocable, and
unconditional guaranty of payment and performance, and not a guaranty of
collection, and each Guarantor shall remain liable on its obligations hereunder
until the payment and performance in full of the Guaranteed Indebtedness. No
set-off, counterclaim, recoupment, reduction, or diminution of any obligation,
or any defense of any kind or nature which Borrower may have against the Agent,
any Co-Agent, any Bank or any other party, or which any Guarantor may have
against Borrower, the Agent, any Co-Agent, any Bank or any other party, shall be
available to, or shall be asserted by, any Guarantor against the Agent, any Co-
Agent, any Bank or any subsequent holder of the Guaranteed Indebtedness or any
part thereof or against payment of the Guaranteed Indebtedness or any part
thereof.

GUARANTY - Page 1
<PAGE>

     3.   The obligations of each Guarantor hereunder shall be limited to an
aggregate amount equal to the largest amount that would not render its
obligations hereunder subject to avoidance under Section 548 of the United
States Bankruptcy Code or to being set aside, avoided, or annulled under any
applicable state law relating to fraudulent transfers or fraudulent obligations.

     4.   If any Guarantor becomes liable for any indebtedness owing by Borrower
to the Agent, any Co-Agent or any Bank by endorsement or otherwise, other than
under this Guaranty, such liability shall not be in any manner impaired or
affected hereby, and the rights of the Agent, the Co-Agents and the Banks
hereunder shall be cumulative of any and all other rights that any of them may
ever have against any Guarantor.  The exercise by the Agent, any Co-Agent or any
Bank of any right or remedy hereunder or under any other instrument, or at law
or in equity, shall not preclude the concurrent or subsequent exercise of any
other right or remedy.

     5.   In the event of default by Borrower in payment or performance of the
Guaranteed Indebtedness, or any part thereof, when such Guaranteed Indebtedness
becomes due, whether by its terms, by acceleration, or otherwise, Guarantors
jointly and severally agree to promptly pay the amount due thereon to the Agent,
for the pro rata benefit of the Banks, without notice or demand in lawful
currency of the United States of America and it shall not be necessary for the
Agent, any Co-Agent or any Bank, in order to enforce such payment by any
Guarantor, first to institute suit or exhaust its remedies against Borrower, any
Guarantor or others liable on such Guaranteed Indebtedness, or to enforce any
rights against any collateral which shall ever have been given to secure such
Guaranteed Indebtedness.  Notwithstanding anything to the contrary contained in
this Guaranty, each Guarantor hereby irrevocably subordinates to the prior
indefeasible payment in full of the Guaranteed Indebtedness, any and all rights
such Guarantor may now or hereafter have under any agreement or at law or in
equity (including, without limitation, any law subrogating such Guarantor to the
rights of the Agent, the Co-Agents and the Banks) to assert any claim against or
seek contribution, indemnification or any other form of reimbursement from
Borrower or any other party liable for payment of any or all of the Guaranteed
Indebtedness for any payment made by such Guarantor under or in connection with
this Guaranty or otherwise.

     6.   If acceleration of the time for payment of any amount payable by
Borrower under the Guaranteed Indebtedness is stayed upon the insolvency,
bankruptcy, or reorganization of Borrower, all such amounts otherwise subject to
acceleration under the terms of the Guaranteed Indebtedness shall nonetheless be
jointly and severally payable by the Guarantors hereunder forthwith on demand by
the Agent.

     7.   Each Guarantor hereby agrees that its obligations under this Guaranty
shall not be released, discharged, diminished, impaired, reduced, or affected
for any reason or by the occurrence of any event, including, without limitation,
one or more of the following events, whether or not with notice to or the
consent of any Guarantor: (a) the taking or accepting of collateral as security
for any or all of the Guaranteed Indebtedness or the release, surrender,
exchange, or subordination of any collateral now or hereafter securing any or
all of the Guaranteed Indebtedness; (b) any partial release

GUARANTY - Page 2
<PAGE>

of the liability of any Guarantor hereunder, or the full or partial release of
any other guarantor from liability for any or all of the Guaranteed
Indebtedness; (c) any disability of Borrower, or the dissolution, insolvency, or
bankruptcy of Borrower, any Guarantor, or any other party at any time liable for
the payment of any or all of the Guaranteed Indebtedness; (d) any renewal,
extension, modification, waiver, amendment, or rearrangement of any or all of
the Guaranteed Indebtedness or any instrument, document, or agreement
evidencing, securing, or otherwise relating to any or all of the Guaranteed
Indebtedness; (e) any adjustment, indulgence, forbearance, waiver, or compromise
that may be granted or given by the Agent, any Co-Agent or any Bank to Borrower,
any Guarantor, or any other party ever liable for any or all of the Guaranteed
Indebtedness; (f) any neglect, delay, omission, failure, or refusal of the
Agent, any Co-Agent or any Bank to take or prosecute any action for the
collection of any of the Guaranteed Indebtedness or to foreclose or take or
prosecute any action in connection with any instrument, document, or agreement
evidencing, securing, or otherwise relating to any or all of the Guaranteed
Indebtedness; (g) the unenforceability or invalidity of any or all of the
Guaranteed Indebtedness or of any instrument, document, or agreement evidencing,
securing, or otherwise relating to any or all of the Guaranteed Indebtedness;
(h) any payment by Borrower or any other party to the Agent, any Co-Agent or any
Bank is held to constitute a preference under applicable bankruptcy or
insolvency law or if for any other reason the Agent, any Co-Agent or any Bank is
required to refund any payment or pay the amount thereof to someone else; (i)
the settlement or compromise of any of the Guaranteed Indebtedness; (j) the non-
perfection of any security interest or lien securing any or all of the
Guaranteed Indebtedness; (k) any impairment of any collateral securing any or
all of the Guaranteed Indebtedness; (l) the failure of the Agent, any Co-Agent
or any Bank to sell any collateral securing any or all of the Guaranteed
Indebtedness in a commercially reasonable manner or as otherwise required by
law; (m) any change in the corporate existence, structure, or ownership of
Borrower; or (n) any other circumstance which might otherwise constitute a
defense available to, or discharge of, Borrower or any Guarantor.

     8.   Each Guarantor represents and warrants to the Agent, the Co-Agents and
the Banks that:

          (a) Each and every representation and warranty contained in the Credit
     Agreement is true and correct in all respects.

          (b) The value of the consideration received and to be received by such
     Guarantor as a result of Borrower, the Banks, the Co-Agents and the Agent
     entering into the Credit Agreement, the extensions of credit thereunder and
     such Guarantor executing and delivering this Guaranty is reasonably
     equivalent to or greater than the liability and obligation of such
     Guarantor hereunder, and such liability and obligation, the Borrower's
     entering into the Credit Agreement and the extensions of credit thereunder
     have benefited and may reasonably be expected to benefit such Guarantor
     directly or indirectly.

GUARANTY - Page 3
<PAGE>

          (c) Such Guarantor has, independently and without reliance upon the
     Agent, any Co-Agent or any Bank and based upon such documents and
     information as such Guarantor has deemed appropriate, made its own analysis
     and decision to enter into this Guaranty.

          (d) The ability of Borrower to borrow and obtain letters of credit
     from time to time under the Credit Agreement will enable such Guarantor to
     obtain credit, will benefit such Guarantor and the consolidated corporate
     group of which such Guarantor is a part and are necessary and convenient to
     the conduct, promotion and attainment of the business of such Guarantor.

          (e) As additional consideration for entering into this Guaranty, such
     Guarantor has obtained certain rights under that certain Contribution and
     Indemnification Agreement of even date herewith, among the Borrower and the
     Guarantors.

          (f) Such Guarantor has adequate capital to conduct its business as a
     going concern, as presently conducted and as proposed to be conducted; such
     Guarantor will be able to meet its obligations hereunder and in respect of
     its other existing and future indebtedness and liabilities as and when the
     same shall be due and payable; such Guarantor is not insolvent (as that
     term is defined in 11 U.S.C. (S) 101 or applicable law) and will not be
     rendered insolvent by its obligations hereunder, and the foregoing
     representations are supported by such Guarantor's internal projections and
     forecasts.

          (g) Such Guarantor has determined that the execution and delivery of
     this Guaranty is to its advantage and benefit, taking into account all
     relevant facts and circumstances.

     9.   If an Event of Default shall have occurred and be continuing, the
Agent and each Bank shall have the right to set off and apply against this
Guaranty or the Guaranteed Indebtedness or both, at any time and without notice
to any Guarantor, any and all deposits (general or special, time or demand,
provisional or final) or other sums at any time credited by or owing from the
Agent, any Co-Agent or any Bank to any Guarantor whether or not the Guaranteed
Indebtedness is then due and irrespective of whether or not the Agent, any Co-
Agent or any Bank shall have made any demand under this Guaranty.  As security
for this Guaranty and the Guaranteed Indebtedness, each Guarantor hereby grants
the Agent, each Co-Agent and each Bank a security interest in all money,
instruments, certificates of deposit, and other property of such Guarantor now
or hereafter held by the Agent, each Co-Agent and each Bank, including without
limitation, property held in safekeeping. In addition to the Agent's, each Co-
Agent's and each Bank's right of setoff and as further security for this
Guaranty and the Guaranteed Indebtedness, each Guarantor hereby grants the
Agent, each Co-Agent and each Bank a security interest in all deposits (general
or special, time or demand, provisional or final) and all other accounts of such
Guarantor now or hereafter on deposit with or held by the Agent, any Co-Agent or
any Bank and all other sums at any time credited by or owing from the Agent, any
Co-Agent or any Bank to such Guarantor.  The rights and remedies of the

<PAGE>

Agent, each Co-Agent and each Bank hereunder are in addition to other rights and
remedies (including, without limitation, other rights of setoff) which the
Agent, each Co-Agent and each Bank may have.

     10.  (a)  Each Guarantor hereby agrees that the Subordinated Indebtedness
(hereinafter defined) shall be subordinate and junior in right of payment to the
prior payment in full of all Guaranteed Indebtedness, and each Guarantor hereby
assigns the Subordinated Indebtedness to the Agent, for the pro rata benefit of
the Banks, as security for the Guaranteed Indebtedness.  If any sums shall be
paid to any Guarantor by Borrower or any other Person on account of the
Subordinated Indebtedness, such sums shall be held in trust by such Guarantor
for the benefit of the Agent and shall forthwith be paid to the Agent, for the
pro rata benefit of the Banks, without affecting the liability of any Guarantor
under this Guaranty and may be applied by the Banks against the Guaranteed
Indebtedness in such order and manner as they may determine in their absolute
discretion; provided, however, that so long as no Event of Default shall have
            --------  -------
occurred, Borrower shall be permitted to pay to any Guarantor, and each
Guarantor shall be permitted to receive and retain, payments on account of
Subordinated Indebtedness consisting of trade payables owing by Borrower to any
Guarantor.  Upon the request of the Agent, each Guarantor shall execute,
deliver, and endorse to the Agent, for the pro rata benefit of the Banks, such
documents and instruments as the Agent may request to perfect, preserve, and
enforce the rights of the Agent and the Banks hereunder.  For purposes of this
Guaranty, the term "Subordinated Indebtedness" means all indebtedness,
                    -------------------------
liabilities, and obligations of Borrower and the Subsidiaries, or any of them,
to any Guarantor, whether such indebtedness, liabilities, and obligations now
exist or are hereafter incurred or arise, or whether the obligations of Borrower
or such Subsidiary thereon are direct, indirect, contingent, primary, secondary,
several, joint, joint and several, or otherwise, and irrespective of whether
such indebtedness, liabilities, or obligations are evidenced by a note,
contract, open account, or otherwise, and irrespective of the Person or Persons
in whose favor such indebtedness, obligations, or liabilities may, at their
inception, have been, or may hereafter be created, or the manner in which they
have been or may hereafter be acquired by any Guarantor.

          (b) Each Guarantor agrees that any and all liens, security interests,
judgment liens, charges, or other encumbrances upon the assets of Borrower and
the Subsidiaries, or any of them, securing payment of any Subordinated
Indebtedness shall be and remain inferior and subordinate to any and all liens,
security interests, judgment liens, charges, or other encumbrances upon such
assets securing payment of the Guaranteed Indebtedness or any part thereof,
regardless of whether such encumbrances in favor of any Guarantor or the Agent
presently exist or are hereafter created or attached.  No Guarantor shall (i)
file suit against Borrower or any Subsidiary or exercise or enforce any other
creditor's right it may have against Borrower or any Subsidiary, or (ii)
foreclose, repossess, sequester, or otherwise take steps or institute any action
or proceedings (judicial or otherwise, including without limitation the
commencement of, or joinder in, any liquidation, bankruptcy, rearrangement,
debtor's relief or insolvency proceeding) to enforce any liens, security
interests, collateral rights, judgments or other encumbrances held by any
Guarantor on assets of

GUARANTY - Page 5
<PAGE>

Borrower or any Subsidiary unless and until the Guaranteed Indebtedness shall
have been paid in full, no Letters of Credit are outstanding, and the
Commitments have expired or terminated.

          (c) In the event of any receivership, bankruptcy, reorganization,
rearrangement, debtor's relief, or other insolvency proceeding involving
Borrower or any Subsidiary as debtor, the Agent shall have the right to prove
and vote any claim under the Subordinated Indebtedness and to receive, for the
benefit of the Banks, directly from the receiver, trustee or other court
custodian all dividends, distributions, and payments made in respect of the
Subordinated Indebtedness. The Agent, the Co-Agents and the Banks may apply any
such dividends, distributions, and payments against the Guaranteed Indebtedness
in such order and manner as they may determine in their absolute discretion.

          (d) Each Guarantor agrees that all promissory notes, accounts
receivable, ledgers, records, or any other evidence of Subordinated Indebtedness
shall contain a specific written notice thereon that the indebtedness evidenced
thereby is subordinated under the terms of this Guaranty.

     11.  No Guarantor shall prepay any Debt, except the Guaranteed
Indebtedness.

     12.  No amendment or waiver of any provision of this Guaranty or consent to
any departure by any Guarantor therefrom shall in any event be effective unless
the same shall be in writing and signed by the Agent and the Required Banks.  No
failure on the part of the Agent, any Co-Agent or any Bank to exercise, and no
delay in exercising, any right, power, or privilege hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power, or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power, or privilege. The remedies herein provided
are cumulative and not exclusive of any remedies provided by law.

     13.  Any acknowledgment or new promise, whether by payment of principal or
interest or otherwise and whether by Borrower or others (including any
Guarantor), with respect to any of the Guaranteed Indebtedness shall, if the
statute of limitations in favor of any Guarantor against the Agent, any Co-Agent
or any Bank shall have commenced to run, toll the running of such statute of
limitations and, if the period of such statute of limitations shall have
expired, prevent the operation of such statute of limitations.

     14.  This Guaranty is for the benefit of the Agent, the Co-Agents and the
Banks and their respective successors and assigns, and in the event of an
assignment of the Guaranteed Indebtedness, or any part thereof, the rights and
benefits hereunder, to the extent applicable to the indebtedness so assigned,
may be transferred with such indebtedness. This Guaranty is binding not only on
each Guarantor, but on each Guarantor's successors and assigns.  The Guarantors'
obligations and agreements hereunder are joint and several.  The provisions of
this Guaranty shall apply to each Guarantor individually and collectively.

     15.  Each Guarantor recognizes that the Agent, the Co-Agents and the Banks
are relying upon this Guaranty and the undertakings of each Guarantor hereunder
in making extensions of credit to Borrower under the Credit Agreement and
further recognizes that the execution and delivery of this Guaranty is a
material inducement to the Agent, the Co-Agents and the Banks in entering into
the Credit Agreement.  Each Guarantor hereby acknowledges that there are no
conditions to the full effectiveness of this Guaranty.

TRANSACTION NEGOTIATED, CONSUMMATED, AND PERFORMABLE IN DALLAS COUNTY, TEXAS,

     17.  Guarantors jointly and severally agree to pay on demand all attorneys'
fees and all other costs and expenses incurred by the Agent and each Bank in
connection with the preparation, administration, enforcement, or collection of
this Guaranty.

     18.  Each Guarantor hereby waives promptness, diligence, notice of any
default under the Guaranteed Indebtedness, demand of payment, notice of
acceptance of this Guaranty, presentment, notice of protest, notice of dishonor,
notice of intent to accelerate, notice of acceleration, notice of the incurring
by Borrower of additional indebtedness, and all other notices and demands with
respect to the Guaranteed Indebtedness and this Guaranty.

     19.  Each Guarantor agrees that the Agent, each Co-Agent and each Bank may
exercise any and all rights granted to them under the Credit Agreement and the
other Loan Documents without affecting the validity or enforceability of this
Guaranty.

     20.  Each Guarantor hereby represents and warrants to the Agent, the Co-
Agents and the Banks that such Guarantor has adequate means to obtain from the
Borrower and the Subsidiaries on a continuing basis information concerning the
financial condition and assets of the Borrower and the Subsidiaries and that
such Guarantor is not relying upon the Agent, any Co-Agent or any Bank to
provide (and neither the Agent, any Co-Agent nor any Bank shall have any duty to
provide) any such information to such Guarantor either now or in the future.

     21.  THIS GUARANTY REPRESENTS THE FINAL AGREEMENT AMONG THE PARTIES AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO ORAL AGREEMENTS AMONG THE PARTIES.

     22.  Each Guarantor acknowledges that it has had the benefit of legal
counsel of its own choice and has been afforded an opportunity to review this

          (h) all extensions, renewals and modifications of any of the
foregoing.

Without limiting the foregoing, this Agreement secures the payment of all
amounts that constitute part of the obligations and would be owed by the
Borrower to the Agent, any Co-Agent or any Bank but for the fact that they are
unenforceable or not allowable due to the existence of bankruptcy,
reorganization, or similar proceedings involving the Borrower.

Collateral free and clear of any Lien or claim or any right or option on the
part of any third Person to purchase or otherwise acquire the Collateral or any
part thereof.  The Collateral is not subject to any restriction on transfer or
assignment except for compliance with applicable federal and state securities
laws and regulations promulgated thereunder.  Pledgor has the unrestricted right
to pledge the Collateral as contemplated hereby.  All of the Collateral has been
duly and validly issued and is fully paid and nonassessable.  Pledgor is the
sole limited partner of the Partnership.

     Section 2.2.   Organization and Authority.  Pledgor is a corporation duly
                    --------------------------
organized, validly existing, and in good standing under the laws of its state of
incorporation.  Pledgor has the corporate power and authority to execute,
deliver, and perform this Agreement, and the execution, delivery, and
performance of this Agreement by Pledgor have been duly authorized by all
necessary corporate action on the part of Pledgor and do not and will not
violate or conflict with the certificate/articles of incorporation or bylaws of
Pledgor or any law, rule or regulation or any order, writ, injunction, or decree
of any Governmental Authority or arbitrator and do not and will not conflict
with, result in a breach of, or constitute a default under the provisions of any
agreement or instrument to which Pledgor is a party or by which Pledgor or any
of its property is bound or subject.

     Section 2.3.   Financing Statements.  No financing statement covering any
                    --------------------
of the Collateral or its proceeds, except financing statements naming the Agent

     Section 2.5.   Percentage of Stock.  The shares of capital stock included
                    -------------------
in the Collateral constitute 100% of the issued and outstanding shares of
capital stock of Florida Properties.

     Section 2.6.   Litigation.  Except as disclosed on Schedule 8.5 to the
                    ----------
Credit Agreement, there is no litigation, investigation, or governmental
proceeding pending or threatened against Pledgor or any of its properties which
if adversely determined would have a material adverse effect on the Collateral
or the financial condition, operations, or business of Pledgor.

     Section 2.7.   First Priority Perfected Security Interest.  Upon the filing
                    ------------------------------------------
of UCC financing statements and Agent's taking possession of the certificates
representing the stock included in the Collateral, this Agreement creates in
favor of the Agent a first priority perfected security interest in the
Collateral.  There are no conditions precedent to the effectiveness of this
Agreement that have not been fully and permanently satisfied.

     Section 2.8.   Benefit to Pledgor.  The value of the consideration received
                    ------------------
and to be received by the Pledgor as a result of the Borrower, the Agent, the
Co-Agents and the Banks entering into the Credit Agreement and the Pledgor
executing and delivering this Agreement is reasonably worth at least as much as
the liability and obligation of the Pledgor hereunder.  Such liability and
obligation of the Pledgor hereunder.  Such liability and obligation and the
Borrower's entering the Credit Agreement have benefited and may reasonably be
expected to benefit the Pledgor directly and indirectly.  The ability of
Borrower to borrow and obtain letters of credit from time to time under the
Credit Agreement will benefit Pledgor and the consolidated corporate group of
which the Pledgor is a part and are necessary and convenient to the conduct,
promotion and attainment of the business of the Pledgor.  The Pledgor has
adequate capital to conduct its business as a going concern, as presently
conducted and as proposed to be conducted.  The Pledgor will be able to  meet
its obligations hereunder and in respect of its other existing and future
indebtedness and liabilities as and when the same shall be due and payable.  The
Pledgor is not insolvent (as that term is defined in 11 U.S.C. (S) 101 or
applicable law) and will not be rendered insolvent by its obligations hereunder.
The foregoing representations are supported by the Pledgor's internal
projections and forecasts.  The Pledgor has determined that the execution and
delivery of this Agreement is to its advantage and benefit, taking into account
all relevant facts and circumstances.

     at any time, or from time to time, all acts and things which the Agent
     deems necessary to protect, preserve, or realize upon the Collateral and

     This power of attorney is a power coupled with an interest and shall be
irrevocable.  The Agent shall be under no duty to exercise or withhold the
exercise of any of the rights, powers, privileges, and options expressly or
implicitly granted to the Agent in this Agreement, and shall not be liable for
any failure to do so or any delay in doing so.  The Agent shall not be liable

acts or omissions resulting from its willful misconduct.  This power of attorney
is conferred on the Agent solely to protect, preserve, and realize upon its

all voting rights pertaining to the Collateral or any part thereof in accordance
with the direction of the Pledgor for any purpose not inconsistent with the
terms of this Agreement or the Credit Agreement.

     Section 4.3.   Dividends and Distributions.  Unless and until an Event of
                    ---------------------------
Default shall have occurred and be continuing, Pledgor shall be entitled to
receive and retain or distribute to Borrower any dividends and distributions on
the Collateral paid in cash to the extent and only to the extent that such
dividends and distributions are permitted by the Credit Agreement, except as
provided in Section 3.4 hereof.
            -----------

     Section 4.4.   Setoff; Property Held by Agents and the Banks.  If an Event
                    ---------------------------------------------
of Default shall have occurred and be continuing, the Agent, each Co-Agent and

any time and without notice to Pledgor, any and all deposits (general or
special, time or demand, provisional or final) or other sums at any time
credited


PLEDGE AGREEMENT - Page 9
[NAC Holdings, Inc.]
<PAGE>

by or owing from the Agent, any Co-Agent or any Bank to Pledgor whether or not
the Obligations are then due. As additional security for the Obligations,
Pledgor hereby grants the Agent, each Co-Agent and each Bank a security interest
in all money, instruments, and other property of Pledgor now or hereafter held
by the Agent, any Co-Agent or any Bank, including, without limitation, property
held in safekeeping. In addition to the Agent's, any Co-Agent's or any Bank's
right of setoff and as further security for the Obligations, Pledgor hereby
grants the Agent, each Co-Agent and each Bank a security interest in all
deposits (general or special, time or demand, provisional or final) and other
accounts of Pledgor now or hereafter on deposit with or held by the Agent, any
Co-Agent or any Bank and all other sums at any time credited by or owing from
the Agent, any Co-Agent or any Bank to Pledgor. The rights and remedies of the
Agent, each Co-Agent and each Bank hereunder are in addition to other rights and
remedies (including, without limitation, other rights of setoff) which the
Agent, any Co-Agent or any Bank may have.

     Section 4.5.   Performance by Agent.  If Pledgor shall fail to perform any
                    --------------------
covenant or agreement contained in this Agreement, the Agent may perform or
attempt to perform such covenant or agreement on behalf of Pledgor.  In such
event, Pledgor shall, at the request of the Agent, promptly pay any amount
expended by the Agent in connection with such performance or attempted
performance to the Agent, together with interest thereon at the Default Rate
from and including the date of such expenditure to but excluding the date such
expenditure is paid in full.  Notwithstanding the foregoing, it is expressly
agreed that the Agent shall not have any liability or responsibility for the
performance of any obligation of Pledgor under this Agreement.

     Section 4.6.   Agent's Duty of Care.  Other than the exercise of reasonable
                    --------------------
care in the physical custody of the Collateral while held by the Agent
hereunder, the Agent shall have no responsibility for or obligation or duty with
respect to all or any part of the Collateral or any matter or proceeding arising
out of or relating thereto, including, without limitation, any obligation or
duty to collect any sums due in respect thereof or to protect or preserve any
rights against prior parties or any other rights pertaining thereto, it being
understood and agreed that Pledgor shall be responsible for preservation of all
rights in the Collateral.  Without limiting the generality of the foregoing, the
Agent shall be conclusively deemed to have exercised reasonable care in the
custody of the Collateral if the Agent takes such action, for purposes of
preserving rights in the Collateral, as Pledgor may reasonably request in
writing, but no failure or omission or delay by the Agent in complying with any
such request by Pledgor, and no refusal by the Agent to comply with any such
request by Pledgor, shall be deemed to be a failure to exercise reasonable care.

     Section 5.1.   Rights and Remedies.  If any Event of Default shall occur,
                    -------------------
the Agent shall have the following rights and remedies:



PLEDGE AGREEMENT - Page 10
[NAC Holdings, Inc.]
<PAGE>

          (i)    In addition to all other rights and remedies granted to the
     Agent in this Agreement and in any other Loan Document or by applicable
     law, the Agent shall have all of the rights and remedies of a secured party
     under the UCC. Without limiting the generality of the foregoing, the Agent
     may (A) without demand or notice to Pledgor, collect, receive, or take
     possession of the Collateral or any part thereof, (B) sell or otherwise
     dispose of the Collateral, or any part thereof, in one or more parcels at
     public or private sale or sales, at the Agent's offices or elsewhere, for
     cash, on credit, or for future delivery, and/or (C) bid and become a
     purchaser at any sale free of any right or equity of redemption in Pledgor,
     which right or equity is hereby expressly waived and released by Pledgor.
     Upon the request of the Agent, Pledgor shall assemble the Collateral and
     make it available to the Agent at any place designated by the Agent that is
     reasonably convenient to Pledgor and the Agent. Pledgor agrees that the
     Agent shall not be obligated to give more than five days written notice of
     the time and place of any public sale or of the time after which any
     private sale may take place and that such notice shall constitute
     reasonable notice of such matters. The Agent shall not be obligated to make
     any sale of the Collateral regardless of notice of sale having been given.
     The Agent may adjourn any public or private sale from time to time by
     announcement at the time and place fixed therefor, and such sale may,
     without further notice, be made at the time and place to which it was so
     adjourned. Pledgor shall be liable for all expenses of retaking, holding,
     preparing for sale, or the like, and all attorneys' fees and other expenses
     incurred by the Agent in connection with the collection of the Obligations
     and the enforcement of the Agent's rights under this Agreement, all of
     which expenses and fees shall constitute additional Obligations secured by
     this Agreement. The Agent may apply the Collateral against the Obligations
     in such order and manner as the Agent may elect in its sole discretion.
     Pledgor shall remain liable for any deficiency if the proceeds of any sale
     or disposition of the Collateral are insufficient to pay the Obligations.
     Pledgor waives all rights of marshalling in respect of the Collateral.

          (ii)   The Agent may cause any or all of the Collateral held by it to
     be transferred into the name of the Agent (if the Agent is not yet the
     registered owner of the Collateral) or the name or names of the Agent's
     nominee or nominees.

          (iii)  The Agent may collect or receive all money or property at any
     time payable or receivable on account of or in exchange for any of the
     Collateral, but shall be under no obligation to do so.

          (iv)   The Agent shall have the right, but shall not be obligated to,
     exercise or cause to be exercised all voting, consensual, and other powers
     of ownership pertaining to the Collateral, including, without limitation,
     all rights, titles and interests of Pledgor as limited partner of the
     Partnership and Pledgor shall deliver to the Agent, if requested by the
     Agent, irrevocable proxies with respect to the Collateral in form
     satisfactory to the Agent.



PLEDGE AGREEMENT - Page 11
[NAC Holdings, Inc.]
<PAGE>

          (v)    The Agent may notify or require Pledgor to notify parties
     obligated under any accounts, instruments, contracts or agreements which
     are part of the Collateral, including, without limitation, the Partnership
     Agreement, to make payment directly to the Agent, and the Agent may take
     possession of all proceeds of any such instruments and contracts in
     Pledgor's possession.  Any such payments or distributions received by
     Pledgor after an Event of Default shall, until paid or delivered to the
     Agent, be held by Pledgor in trust as additional security for the
     Obligations.

          (vi)   Pledgor hereby acknowledges and confirms that the Agent may be
     unable to effect a public sale of any or all of the Collateral by reason of
     certain prohibitions contained in the Securities Act of 1933, as amended,
     and applicable state securities laws and may be compelled to resort to one
     or more private sales thereof to a restricted group of purchasers who will
     be obligated to agree, among other things, to acquire any shares of the
     Collateral for their own respective accounts for investment and not with a

     confirms that any such private sale may result in prices or other terms

     be deemed to have been made in a commercially reasonable manner, and the
     Agent shall be under no obligation to take any steps in order to permit the
     Collateral to be sold at a public sale.  The Agent shall be under no
     obligation to delay a sale of any of the Collateral for any period of time
     necessary to permit any issuer thereof to register such Collateral for
     public sale under the Securities Act of 1933, as amended, or under
     applicable state securities laws.

          (vii)  On any sale of the Collateral, the Agent is hereby authorized
     to comply with any limitation or restriction with which compliance is
     necessary, in the view of the Agent's counsel, in order to avoid any
     violation of applicable law or in order to obtain any required approval of
     the purchaser or purchasers by any applicable governmental authority.

          (viii) The Agent may subrogate to all of Pledgor's interests, rights,
     and remedies with respect to any of the Collateral.

right of Pledgor to receive cash dividends and distributions under Section 4.3

own name, to take any and all action and to execute any and all documents and
instruments which the Agent at any time and from time to time deems necessary or
desirable to accomplish the purposes of this Agreement and, without limiting the
generality of the foregoing, Pledgor hereby gives the Agent the power and right
on behalf of Pledgor and in its own name to do any of the following (subject to
the rights of Pledgor under Sections 4.2 and 4.3 hereof), without notice to or
                            ------------     ---

     Event of Default, to receive payment of and receipt for any and all monies,
     claims, and other amounts due and to become due at any time in respect of
     or arising out of any Collateral; (C) after the occurrence and during the

     deposit any of the Collateral with any committee, depositary, transfer
     agent, registrar, or other designated agency upon such terms as the Agent
     may determine; (H) to add or release any guarantor, indorser, surety, or
     other party to any of the Collateral or the Obligations; (I) to renew,
     extend, or otherwise change the terms and conditions of any of the
     Collateral or Obligations; and (J) after the occurrence and during the
     continuance of an Event of Default, to sell, transfer, pledge, make any
     agreement with respect to or otherwise deal with any of the Collateral as
     fully and completely as though the Agent were the absolute owner thereof
     for all purposes, and to do, at the Agent's option and Pledgor's expense,
     at any time, or from time to time, all acts and things which the Agent
     deems necessary to protect, preserve, or realize upon the Collateral and
     the Agent's security interest therein.

     This power of attorney is a power coupled with an interest and shall be
irrevocable.  The Agent shall be under no duty to exercise or withhold the
exercise of any of the rights, powers, privileges, and options expressly or
implicitly granted to the Agent in this Agreement, and shall not be liable for
any failure to do so or any delay in doing so.  The Agent shall not be liable
for any act or omission or for any error of judgment or any mistake of fact or
law in its individual capacity or in its capacity as attorney-in-fact except
acts or omissions resulting from its willful misconduct.  This power of attorney
is conferred on the Agent solely to protect, preserve, and realize upon its
security interest in the Collateral.  The Agent will exercise its best efforts
to notify Pledgor of any action taken by the Agent in its capacity as attorney-
in-fact pursuant to this Section, promptly after such action is taken provided
that any failure by the Agent to so notify Pledgor shall not impose any
liability upon the Agent or affect its rights and remedies hereunder, at law or
in equity.  The Agent shall not be responsible for any decline in the value of
the Collateral and shall not be required to take any steps to preserve rights
against prior parties or to protect, preserve, or maintain any security interest
or Lien given to secure the Collateral.

     Section 4.2.   Voting Rights.  Unless and until an Event of Default shall
                    -------------
have occurred and be continuing, Pledgor shall be entitled to exercise any and
all voting rights pertaining to the Collateral or any part thereof in accordance
with the direction of the Pledgor for any purpose not inconsistent with the
terms of this Agreement or the Credit Agreement.

     Section 4.3.   Dividends and Distributions.  Unless and until an Event of
                    ---------------------------
Default shall have occurred and be continuing, Pledgor shall be entitled to
receive and retain or distribute to Pledgor any dividends and distributions on
the Collateral paid in cash to the extent and only to the extent that such
dividends and distributions are permitted by the Credit Agreement, except as
provided in Section 3.4 hereof.
            -----------

     Section 4.4.   Setoff; Property Held by Agents and the Banks.  If an Event
                    ---------------------------------------------
of Default shall have occurred and be continuing, the Agent, each Co-Agent and
each Bank shall have the right to set off and apply against the Obligations, at
any time and without notice to Pledgor, any and all deposits (general or
special, time or demand, provisional or final) or other sums at any time
credited

PLEDGE AGREEMENT - Page 8
[Borrower]
<PAGE>

by or owing from the Agent, any Co-Agent or any Bank to Pledgor whether or not
the Obligations are then due. As additional security for the Obligations,
Pledgor hereby grants the Agent, each Co-Agent and each Bank a security interest
in all money, instruments, and other property of Pledgor now or hereafter held
by the Agent, any Co-Agent or any Bank, including, without limitation, property
held in safekeeping. In addition to the Agent's, any Co-Agent's or any Bank's
right of setoff and as further security for the Obligations, Pledgor hereby
grants the Agent, each Co-Agent and each Bank a security interest in all
deposits (general or special, time or demand, provisional or final) and other
accounts of Pledgor now or hereafter on deposit with or held by the Agent, any
Co-Agent or any Bank and all other sums at any time credited by or owing from
the Agent, any Co-Agent or any Bank to Pledgor. The rights and remedies of the
Agent, each Co-Agent and each Bank hereunder are in addition to other rights and
remedies (including, without limitation, other rights of setoff) which the
Agent, any Co-Agent or any Bank may have.

     Section 4.5.   Performance by Agent.  If Pledgor shall fail to perform any
                    --------------------
covenant or agreement contained in this Agreement, the Agent may perform or
attempt to perform such covenant or agreement on behalf of Pledgor.  In such
event, Pledgor shall, at the request of the Agent, promptly pay any amount
expended by the Agent in connection with such performance or attempted
performance to the Agent, together with interest thereon at the Default Rate
from and including the date of such expenditure to but excluding the date such
expenditure is paid in full.  Notwithstanding the foregoing, it is expressly
agreed that the Agent shall not have any liability or responsibility for the
performance of any obligation of Pledgor under this Agreement.

     Section 4.6.   Agent's Duty of Care.  Other than the exercise of reasonable
                    --------------------
care in the physical custody of the Collateral while held by the Agent
hereunder, the Agent shall have no responsibility for or obligation or duty with
respect to all or any part of the Collateral or any matter or proceeding arising
out of or relating thereto, including, without limitation, any obligation or
duty to collect any sums due in respect thereof or to protect or preserve any
rights against prior parties or any other rights pertaining thereto, it being
understood and agreed that Pledgor shall be responsible for preservation of all
rights in the Collateral.  Without limiting the generality of the foregoing, the
Agent shall be conclusively deemed to have exercised reasonable care in the
custody of the Collateral if the Agent takes such action, for purposes of
preserving rights in the Collateral, as Pledgor may reasonably request in
writing, but no failure or omission or delay by the Agent in complying with any
such request by Pledgor, and no refusal by the Agent to comply with any such
request by Pledgor, shall be deemed to be a failure to exercise reasonable care.

                                   ARTICLE V

                                    Default
                                    -------

     Section 5.1.   Rights and Remedies.  If any Event of Default shall occur,
                    -------------------
the Agent shall have the following rights and remedies:

PLEDGE AGREEMENT - Page 9
[Borrower]
<PAGE>

          (i)  In addition to all other rights and remedies granted to the Agent
     in this Agreement and in any other Loan Document or by applicable law, the
     Agent shall have all of the rights and remedies of a secured party under
     the UCC.  Without limiting the generality of the foregoing, the Agent may
     (A) without demand or notice to Pledgor, collect, receive, or take
     possession of the Collateral or any part thereof, (B) sell or otherwise
     dispose of the Collateral, or any part thereof, in one or more parcels at
     public or private sale or sales, at the Agent's offices or elsewhere, for
     cash, on credit, or for future delivery, and/or (C) bid and become a
     purchaser at any sale free of any right or equity of redemption in Pledgor,
     which right or equity is hereby expressly waived and released by Pledgor.
     Upon the request of the Agent, Pledgor shall assemble the Collateral and
     make it available to the Agent at any place designated by the Agent that is
     reasonably convenient to Pledgor and the Agent.  Pledgor agrees that the
     Agent shall not be obligated to give more than five days written notice of
     the time and place of any public sale or of the time after which any
     private sale may take place and that such notice shall constitute
     reasonable notice of such matters.  The Agent shall not be obligated to
     make any sale of the Collateral regardless of notice of sale having been
     given. The Agent may adjourn any public or private sale from time to time
     by announcement at the time and place fixed therefor, and such sale may,
     without further notice, be made at the time and place to which it was so
     adjourned.  Pledgor shall be liable for all expenses of retaking, holding,
     preparing for sale, or the like, and all attorneys' fees and other expenses
     incurred by the Agent in connection with the collection of the Obligations
     and the enforcement of the Agent's rights under this Agreement, all of
     which expenses and fees shall constitute additional Obligations secured by
     this Agreement.  The Agent may apply the Collateral against the Obligations
     in such order and manner as the Agent may elect in its sole discretion.
     Pledgor shall remain liable for any deficiency if the proceeds of any sale
     or disposition of the Collateral are insufficient to pay the Obligations.
     Pledgor waives all rights of marshalling in respect of the Collateral.

          (ii)  The Agent may cause any or all of the Collateral held by it to
     be transferred into the name of the Agent (if the Agent is not yet the
     registered owner of the Collateral) or the name or names of the Agent's
     nominee or nominees.

          (iii) The Agent may collect or receive all money or property at any
     time payable or receivable on account of or in exchange for any of the
     Collateral, but shall be under no obligation to do so.

          (iv)  The Agent shall have the right, but shall not be obligated to,
     exercise or cause to be exercised all voting, consensual, and other powers
     of ownership pertaining to the Collateral, and Pledgor shall deliver to the
     Agent, if requested by the Agent, irrevocable proxies with respect to the
     Collateral in form satisfactory to the Agent.

          (v)   The Agent may notify or require Pledgor to notify parties
     obligated under any accounts, instruments, contracts or agreements which
     are part of the Collateral, to make

PLEDGE AGREEMENT - Page 10
[Borrower]
<PAGE>

     payment directly to the Agent, and the Agent may take possession of all
     proceeds of any such instruments and contracts in Pledgor's possession. Any
     such payments or distributions received by Pledgor after an Event of
     Default shall, until paid or delivered to the Agent, be held by Pledgor in
     trust as additional security for the Obligations.

          (vi)  Pledgor hereby acknowledges and confirms that the Agent may be
     unable to effect a public sale of any or all of the Collateral by reason of
     certain prohibitions contained in the Securities Act of 1933, as amended,
     and applicable state securities laws and may be compelled to resort to one
     or more private sales thereof to a restricted group of purchasers who will
     be obligated to agree, among other things, to acquire any shares of the
     Collateral for their own respective accounts for investment and not with a
     view to distribution or resale thereof.  Pledgor further acknowledges and
     confirms that any such private sale may result in prices or other terms
     less favorable to the seller than if such sale were a public sale and,
     notwithstanding such circumstances, agrees that any such private sale shall
     be deemed to have been made in a commercially reasonable manner, and the
     Agent shall be under no obligation to take any steps in order to permit the
     Collateral to be sold at a public sale.  The Agent shall be under no
     obligation to delay a sale of any of the Collateral for any period of time
     necessary to permit any issuer thereof to register such Collateral for
     public sale under the Securities Act of 1933, as amended, or under
     applicable state securities laws.

          (vii)  On any sale of the Collateral, the Agent is hereby authorized
     to comply with any limitation or restriction with which compliance is
     necessary, in the view of the Agent's counsel, in order to avoid any
     violation of applicable law or in order to obtain any required approval of
     the purchaser or purchasers by any applicable governmental authority.

          (viii) The Agent may subrogate to all of Pledgor's interests, rights,
     and remedies with respect to any of the Collateral.

                                  ARTICLE VI

with this Agreement or any other Loan Document, including, without limitation,

Collateral.

no course of dealing with respect to, any right, power, or privilege under this
Agreement shall operate as a waiver thereof, nor shall any single or partial

deliver, and perform this Agreement, and the execution, delivery, and
performance of this Agreement by Pledgor have been duly authorized by all

     Section 2.6.   First Priority Perfected Security Interest.  Upon the filing
                    ------------------------------------------

favor of the Agent a first priority perfected security interest in the

     Section 2.7.   Benefit to Pledgor.  The value of the consideration received
                    ------------------
and to be received by the Pledgor as a result of the Borrower, the Agent, the
Co-Agents and the Banks entering into the Credit Agreement and the Pledgor
executing and delivering this Agreement is reasonably worth at least as much as
the liability and obligation of the Pledgor hereunder.  Such liability and
obligation of the Pledgor hereunder.  Such liability and obligation and the
Borrower's entering the Credit Agreement have benefited and may reasonably be
expected to benefit the Pledgor directly and indirectly.  The ability of
Borrower to borrow and obtain letters of credit from time to time under the
Credit Agreement will benefit Pledgor and the consolidated corporate group of
which the Pledgor is a part and are necessary and convenient to the conduct,
promotion and attainment of the business of the Pledgor.  The Pledgor has
adequate capital to conduct its business as a going concern, as presently
conducted and as proposed to be conducted.  The Pledgor will be able to  meet
its obligations hereunder and in respect of its other existing and future
indebtedness and liabilities as and when the same shall be due and payable.  The
Pledgor is not insolvent (as that term is defined in 11 U.S.C. (S) 101 or
applicable law) and will not be rendered insolvent by its obligations hereunder.
The foregoing representations are supported by the Pledgor's internal
projections and forecasts.  The Pledgor has determined that the execution and
delivery of this Agreement is to its advantage and benefit, taking into account
all relevant facts and circumstances.

                                   ARTICLE III

                       Affirmative and Negative Covenants
                       ----------------------------------

     Pledgor covenants and agrees with the Agent that until the Obligations are
paid and performed in full and all Commitments have terminated:

     Section 3.1.   Delivery.  Prior to or concurrently with the execution and

delivery of this Agreement, Pledgor shall deliver to the Agent all certificates
evidencing any Collateral existing on the date hereof, accompanied by
endorsements duly executed in blank.

     Section 3.2.   Encumbrances.  Pledgor shall not create, permit, or suffer
                    ------------
to exist, and shall defend the Collateral against, any Lien on the Collateral

and the Agent's security interest in the Collateral against the claims and

     things which the Agent deems necessary to protect, preserve, or realize

PLEDGE AGREEMENT - Page 8

<PAGE>

     This power of attorney is a power coupled with an interest and shall be
irrevocable.  The Agent shall be under no duty to exercise or withhold the
exercise of any of the rights, powers, privileges, and options expressly or
implicitly granted to the Agent in this Agreement, and shall not be liable for
any failure to do so or any delay in doing so.  The Agent shall not be liable
for any act or omission or for any error of judgment or any mistake of fact or
law in its individual capacity or in its capacity as attorney-in-fact except
acts or omissions resulting from its willful misconduct.  This power of attorney
is conferred on the Agent solely to protect, preserve, and realize upon its
security interest in the Collateral.  The Agent will exercise its best efforts
to notify Pledgor of any action taken by the Agent in its capacity as attorney-
in-fact pursuant to this Section, promptly after such action is taken provided
that any failure by the Agent to so notify Pledgor shall not impose any
liability upon the Agent or affect its rights and remedies hereunder, at law or
in equity.  The Agent shall not be responsible for any decline in the value of
the Collateral and shall not be required to take any steps to preserve rights
against prior parties or to protect, preserve, or maintain any security interest
or Lien given to secure the Collateral.

     Section 4.2.   Voting Rights.  Unless and until an Event of Default shall
                    -------------
have occurred and be continuing, Pledgor shall be entitled to exercise any and
all voting rights pertaining to the Collateral or any part thereof in accordance
with the direction of the Pledgor for any purpose not inconsistent with the
terms of this Agreement or the Credit Agreement.

     Section 4.3.   Dividends and Distributions.  Unless and until an Event of
                    ---------------------------
Default shall have occurred and be continuing, Pledgor shall be entitled to
receive and retain or distribute to Borrower any dividends and distributions on
the Collateral paid in cash to the extent and only to the extent that such
dividends and distributions are permitted by the Credit Agreement, except as
provided in Section 3.4 hereof.
            -----------

     Section 4.4.   Setoff; Property Held by Agents and the Banks.  If an Event
                    ---------------------------------------------
of Default shall have occurred and be continuing, the Agent, each Co-Agent and
each Bank shall have the right to set off and apply against the Obligations, at
any time and without notice to Pledgor, any and all deposits (general or
special, time or demand, provisional or final) or other sums at any time
credited by or owing from the Agent, any Co-Agent or any Bank to Pledgor whether
or not the Obligations are then due.  As additional security for the
Obligations, Pledgor hereby grants the Agent, each Co-Agent and each Bank a
security interest in all money, instruments, and other property of Pledgor now
or hereafter held by the Agent, any Co-Agent or any Bank, including, without
limitation, property held in safekeeping.  In addition to the Agent's, any Co-
Agent's or any Bank's right of setoff and as further security for the
Obligations, Pledgor hereby grants the Agent, each Co-Agent and each Bank a
security interest in all deposits (general or special, time or demand,
provisional or final) and other accounts of Pledgor now or hereafter on deposit
with or held by the Agent, any Co-Agent or any Bank and all other sums at any
time credited by or owing from the Agent, any Co-Agent or any Bank to Pledgor.
The rights and remedies of the Agent, each Co-Agent and each Bank hereunder are
in addition to other rights and remedies (including, without limitation, other
rights of setoff) which the Agent, any Co-Agent or any Bank may have.

     Section 4.5.   Performance by Agent.  If Pledgor shall fail to perform any
                    --------------------
covenant or agreement contained in this Agreement, the Agent may perform or
attempt to perform such covenant or agreement on behalf of Pledgor.  In such
event, Pledgor shall, at the request of the Agent, promptly pay any amount
expended by the Agent in connection with such performance or attempted
performance to the Agent, together with interest thereon at the Default Rate
from and including the date of such expenditure to but excluding the date such
expenditure is paid in full.  Notwithstanding the foregoing, it is expressly
agreed that the Agent shall not have any liability or responsibility for the
performance of any obligation of Pledgor under this Agreement.

     Section 4.6.   Agent's Duty of Care.  Other than the exercise of reasonable
                    --------------------
care in the physical custody of the Collateral while held by the Agent
hereunder, the Agent shall have no responsibility for or obligation or duty with
respect to all or any part of the Collateral or any matter or proceeding arising
out of or relating thereto, including, without limitation, any obligation or
duty to collect any sums due in respect thereof or to protect or preserve any
rights against prior parties or any other rights pertaining thereto, it being
understood and agreed that Pledgor shall be responsible for preservation of all
rights in the Collateral.  Without limiting the generality of the foregoing, the
Agent shall be conclusively deemed to have exercised reasonable care in the
custody of the Collateral if the Agent takes such action, for purposes of
preserving rights in the Collateral, as Pledgor may reasonably request in
writing, but no failure or omission or delay by the Agent in complying with any
such request by Pledgor, and no refusal by the Agent to comply with any such
request by Pledgor, shall be deemed to be a failure to exercise reasonable care.

                                   ARTICLE V

                                    Default
                                    -------

     Section 5.1.   Rights and Remedies.  If any Event of Default shall occur,
                    -------------------
the Agent shall have the following rights and remedies:

          (i)   In addition to all other rights and remedies granted to the
     Agent in this Agreement and in any other Loan Document or by applicable
     law, the Agent shall have all of the rights and remedies of a secured party
     under the UCC. Without limiting the generality of the foregoing, the Agent
     may (A) without demand or notice to Pledgor, collect, receive, or take
     possession of the Collateral or any part thereof, (B) sell or otherwise
     dispose of the Collateral, or any part thereof, in one or more parcels at
     public or private sale or sales, at the Agent's offices or elsewhere, for
     cash, on credit, or for future delivery, and/or (C) bid and become a
     purchaser at any sale free of any right or equity of redemption in Pledgor,
     which right or equity is hereby expressly waived and released by Pledgor.
     Upon the request of the Agent, Pledgor shall assemble the Collateral and
     make it available to the Agent at any place designated by the Agent that is
     reasonably convenient to Pledgor and the Agent.  Pledgor agrees that the
     Agent shall not be obligated to give more than five days written notice of
     the time and place of any public sale or of the time after which any
     private sale may take place

PLEDGE AGREEMENT - Page 10
[NAC]
<PAGE>

     and that such notice shall constitute reasonable notice of such matters.
     The Agent shall not be obligated to make any sale of the Collateral
     regardless of notice of sale having been given. The Agent may adjourn any
     public or private sale from time to time by announcement at the time and
     place fixed therefor, and such sale may, without further notice, be made at
     the time and place to which it was so adjourned. Pledgor shall be liable
     for all expenses of retaking, holding, preparing for sale, or the like, and
     all attorneys' fees and other expenses incurred by the Agent in connection
     with the collection of the Obligations and the enforcement of the Agent's
     rights under this Agreement, all of which expenses and fees shall
     constitute additional Obligations secured by this Agreement. The Agent may
     apply the Collateral against the Obligations in such order and manner as
     the Agent may elect in its sole discretion. Pledgor shall remain liable for
     any deficiency if the proceeds of any sale or disposition of the Collateral
     are insufficient to pay the Obligations. Pledgor waives all rights of
     marshalling in respect of the Collateral.

          (ii)  The Agent may cause any or all of the Collateral held by it to
     be transferred into the name of the Agent (if the Agent is not yet the
     registered owner of the Collateral) or the name or names of the Agent's
     nominee or nominees.

          (iii) The Agent may collect or receive all money or property at any
     time payable or receivable on account of or in exchange for any of the
     Collateral, but shall be under no obligation to do so.

          (iv)  The Agent shall have the right, but shall not be obligated to,
     exercise or cause to be exercised all voting, consensual, and other powers
     of ownership pertaining to the Collateral, including, without limitation,
     all rights, titles and interests of Pledgor as general partner of the
     Partnership, and Pledgor shall deliver to the Agent, if requested by the
     Agent, irrevocable proxies with respect to the Collateral in form
     satisfactory to the Agent.

          (v)   The Agent may notify or require Pledgor to notify parties
     obligated under any accounts, instruments, contracts or agreements which
     are part of the Collateral, including, without limitation, the Partnership
     Agreement, to make payment directly to the Agent, and the Agent may take
     possession of all proceeds of any such instruments and contracts in
     Pledgor's possession.  Any such payments or distributions received by
     Pledgor after an Event of Default shall, until paid or delivered to the
     Agent, be held by Pledgor in trust as additional security for the
     Obligations.

          (vi)  Pledgor hereby acknowledges and confirms that the Agent may be
     unable to effect a public sale of any or all of the Collateral by reason of
     certain prohibitions contained in the Securities Act of 1933, as amended,
     and applicable state securities laws and may be compelled to resort to one
     or more private sales thereof to a restricted group of purchasers who will
     be obligated to agree, among other things, to acquire any shares of the
     Collateral for their own respective accounts for investment and not with a
     view to distribution or resale
<PAGE>

     thereof. Pledgor further acknowledges and confirms that any such private
     sale may result in prices or other terms less favorable to the seller than
     if such sale were a public sale and, notwithstanding such circumstances,
     agrees that any such private sale shall be deemed to have been made in a
     commercially reasonable manner, and the Agent shall be under no obligation
     to take any steps in order to permit the Collateral to be sold at a public
     sale. The Agent shall be under no obligation to delay a sale of any of the
     Collateral for any period of time necessary to permit any issuer thereof to
     register such Collateral for public sale under the Securities Act of 1933,
     as amended, or under applicable state securities laws.

          (vii)  On any sale of the Collateral, the Agent is hereby authorized
     to comply with any limitation or restriction with which compliance is
     necessary, in the view of the Agent's counsel, in order to avoid any
     violation of applicable law or in order to obtain any required approval of
     the purchaser or purchasers by any applicable governmental authority.

          (viii) The Agent may subrogate to all of Pledgor's interests, rights,
     and remedies with respect to any of the Collateral.

                                  ARTICLE VI

                                 Miscellaneous

duties or obligations under the contracts and agreements included in the

the Collateral in favor of the Agent.  Upon the filing of UCC financing
statements in favor of the Agent in the jurisdictions listed on Schedule 2
                                                                ----------
attached hereto, and upon the Agent's obtaining possession of all Documents and

herein will constitute a valid and perfected Lien upon and security interest in
the Collateral, subject to no equal or prior Lien, except the Permitted Liens.

     Section 3.7.   Benefit to Debtors.  The value of the consideration received
                    ------------------
and to be received by each Debtor as a result of the Borrower, the Agent, the
Co-Agents and the Banks entering into and obtaining credit under the Credit
Agreement and the Debtors executing and delivering this Agreement is reasonably
worth at least as much as the liability and obligation of such Debtor hereunder,
and such liability and obligation and the Borrower's entering into and obtaining
credit under the Credit Agreement have benefited and may reasonably be expected
to benefit each Debtor directly and indirectly.

     Section 3.8.   Credit Agreement.  Each and every representation and
                    ----------------
warranty contained in the Credit Agreement is true and correct in all respects.

                                   ---------

     The Debtors jointly and severally covenant and agree with the Agent that
until the Obligations are paid and performed in full and all Commitments have
terminated:

     Section 4.1.   Encumbrances.  No Debtor shall create, permit, or suffer to
                    ------------
exist, and each Debtor shall defend the Collateral against, any Lien on the
Collateral, except the Permitted Liens, and each Debtor shall defend its rights
in the Collateral and the Agent's security interest in the Collateral against
the claims and demands of all Persons.  No Debtor shall do anything to impair
the rights of the Agent in the Collateral.

     Section 4.2.   Modification of Accounts.  Each Debtor shall, in accordance
                    ------------------------
with prudent business practices, endeavor to collect or cause to be collected
from each account debtor under its Accounts, as and when due, any and all
amounts owing under such Accounts.  Without the prior written consent of the
Agent, no Debtor shall (a) grant any extension of time for any payment with
respect to any of the Accounts, except for extensions of time granted in the
ordinary course of such Debtor's business for payment with respect to Accounts
not included in the Borrowing Base, (b)

course of business of Accounts not included in the Borrowing Base, (c) release,
in whole or in part, any Person liable for payment thereof, except in connection
with settlements permitted by clause (b) above, (d) allow any credit or discount
                              ----------
for payment with respect to any Account other than trade discounts granted in
the ordinary course of business, or (e) release any Lien or guaranty securing
any Account, except in connection with settlements permitted by clause (b)
above.

     Section 4.3.   Disposition of Collateral.  No Debtor shall sell, lease,
                    -------------------------
assign (by operation of law or otherwise), or otherwise dispose of, or grant any

written consent of the Agent, except as expressly permitted by the Credit
Agreement.

     Section 4.4.   Further Assurances.  At any time and from time to time, upon
                    ------------------
the request of the Agent, and at the sole expense of the Debtors, each Debtor
shall promptly execute and deliver all such further instruments, agreements, and
documents and take such further action as the Agent may deem necessary or
desirable to preserve and perfect its security interest in the Collateral and
carry out the provisions and purposes of this Agreement.  Without limiting the
generality of the foregoing, each Debtor shall (a) execute and deliver to the
Agent such financing statements as the Agent may from time to time require; (b)
deliver and pledge to the Agent all Documents (including, without limitation,
negotiable documents of title) evidencing Inventory or Equipment; (c) deliver
and pledge to the Agent all Instruments and Chattel Paper of such Debtor with
any necessary endorsements; and (d) execute and deliver to the Agent such other

relating to all or any part of the Collateral without the signature of such
Debtor where permitted by law.  A carbon, photographic, or other reproduction of
this Agreement or of any financing statement covering the Collateral or any part
thereof shall be sufficient as a financing statement and may be filed as a
financing statement.

     Section 4.5.   Risk of Loss; Insurance.  The Debtors shall be responsible
                    -----------------------
for any loss or damage to the Collateral.  The Debtors shall, at their own
expense, maintain or cause to be maintained insurance with respect to the
Collateral in such amounts, against such risks, in such form, and with such
insurers as shall be satisfactory to the Agent from time to time.  Each policy
for liability insurance shall provide for all losses to be paid on behalf of the
Agent, for the pro rata benefit of the Banks and the Debtor as their interests
may appear.  Each policy for property insurance shall contain loss payable
clauses and a loss payable endorsement in favor of the Agent, for the pro rata
benefit of the Banks, as its interest may appear.  If the Debtors shall fail to
maintain or cause to be maintained the insurance required by this Agreement, the
Agent shall have the right (but shall be under no obligation) to obtain such
insurance and the Debtors jointly and severally agree to reimburse the Agent for
all costs and expenses incurred by the Agent in obtaining such insurance. All
such insurance shall provide that no cancellation, reduction in amount, or
change in coverage thereof shall be effective unless the Agent has received 30
days prior written notice thereof.  The

any reasonable time and as often as the Agent or any such Bank may desire during
normal business hours.  The Agent and each Bank may at any time and from time to
time contact account debtors and other obligors to verify the existence,
amounts, and terms of any Debtor's Accounts.

     Section 4.7.   Mortgagee's and Landlord's Agreements.  With respect to each
                    -------------------------------------
location of Inventory having an aggregate value of $100,000 or more, as
specified on Schedule 1 hereto, each Debtor shall cause each mortgagee of real
             ----------
property owned by such Debtor and each landlord of real property leased by such
Debtor who has not previously done so to execute and deliver to the Agent, on or
before the date hereof, instruments satisfactory in form and substance to the
Agent by which such mortgagee or landlord waives its rights, if any, in the
Collateral (each, a "Landlord's Agreement").  After the date hereof, each Debtor
                     --------------------
shall promptly deliver or cause to be delivered to the Agent Landlord's
Agreements in accordance with this Section for each location where the Inventory
hereafter has an aggregate value of $100,000 or more.  At the request of the
Agent, each Debtor shall promptly deliver or cause to be delivered Landlord's
Agreements for any locations where any Collateral may now or hereafter be
located.

     Section 4.8.   Corporate Changes.  No Debtor shall change its name,
                    -----------------
identity, or corporate structure in any manner that might make any financing
statement filed in connection with this Agreement seriously misleading unless
such Debtor shall have given the Agent 30 days prior written notice thereof and
shall have taken all action deemed necessary or desirable by the Agent to make
each financing statement not seriously misleading.  No Debtor shall change its
principal place of business, chief executive office, or the place where it keeps
its books and records unless it shall have given the Agent 30 days prior written
notice thereof and shall have taken all action deemed necessary or desirable by
the Agent to cause its security interest in the Collateral to be perfected with
the priority required by this Agreement.

     Section 4.9.   Books and Records; Information.  The Debtors shall keep
                    ------------------------------
accurate and complete books and records of the Collateral and the Debtors'
business and financial condition in accordance with GAAP.  Each Debtor shall
from time to time at the request of the Agent deliver to the Agent such
information regarding the Collateral and such Debtor as the Agent may request,
including, without limitation, lists and descriptions of the Collateral and
evidence of the identity and existence of the Collateral.  Each Debtor shall
mark its books and records to reflect the security interest of the Agent under
this Agreement.

                    -----------------------

          (b) The Debtors shall keep the Equipment and Inventory at the
     locations specified on Schedule 1 hereto or, upon 30 days prior written
                            ----------
     notice to the Agent, at such other places within the United States of
     America where all action required to perfect the Agent's security interest
     in the Equipment and Inventory with the priority required by this Agreement
     shall have been taken.

          (d) The Debtors shall maintain the Equipment and Inventory in good
     condition and repair (ordinary wear and tear excepted).  None of the
     Debtors shall permit any waste or destruction of the Equipment or Inventory
     or any part thereof.  None of the Debtors shall permit the Equipment or
     Inventory to be used in violation of any law, rule, or regulation or
     inconsistently with the terms of any policy of insurance.  None of the
     Debtors shall use or permit any of the Equipment or Inventory to be used in
     any manner or for any purpose that would impair its value or expose it to
     unusual risk.

     Section 4.11.  Warehouse Receipts Non-Negotiable.  Each Debtor agrees that
                    ---------------------------------
if any warehouse receipt or receipt in the nature of a warehouse receipt is
issued in respect of any of the Collateral, such warehouse receipt or receipt in
the nature thereof shall not be "negotiable" (as such term is used in Section
7.104 of the UCC as in effect in any relevant jurisdiction or under relevant
law).

     Section 4.12.  Notification.  The Debtors shall promptly, and in any event
                    ------------
within five days after any Debtor obtains knowledge or becomes aware of any of
the following, notify the Agent of (a) any Lien or claim that has attached to or
been made or asserted against any of the Collateral, (b) any material damage to
or loss of any of the Collateral, (c) the occurrence of any other event that
could have a material adverse effect on the Collateral or the security interest
created hereunder, and (d) the occurrence or existence of any Default.

     Section 4.13.  Collection of Accounts.  Except as otherwise provided in
                    ----------------------
this Section, the Debtors shall have the right to collect and receive payments
on the Accounts.  In connection with such collections, the Debtors may take
(and, at the Agent's direction, shall take) such actions as the Debtors or the
Agent may deem necessary or advisable to enforce collection of the Accounts.  At
any time, if an Event of Default shall have occurred and be continuing, the
Agent shall have the right to, or upon the request of the Agent the Debtors
shall, instruct all account debtors and other Persons obligated in respect of
the Accounts to make all payments on the Accounts either (a) directly to the
Agent (by instructing that such payments be remitted to a post office box which
shall be in the name and under the control of the Agent), or (b) to one or more
other banks in the United States of America (by instructing that such payments
be remitted to a post office box which shall be in the name or under the control
of the Agent) under arrangements in form and substance satisfactory to the Agent
pursuant to which the Debtors shall have irrevocably instructed such other bank
(and such other bank shall have agreed) to remit all such payments directly to
the Agent.  In addition to the foregoing, each Debtor agrees that if any
Proceeds of any Collateral (including payments made in respect of Accounts)
shall be received by such Debtor while an Event of Default exists, such Debtor

GUARANTOR SECURITY AGREEMENT - PAGE 9
<PAGE>

shall promptly deliver such Proceeds to the Agent, for the pro rata benefit of
the Banks, with any necessary endorsements. Until such Proceeds are delivered to
the Agent, such Proceeds shall be held in trust by such Debtor for the benefit
of the Agent and shall not be commingled with any other funds or property of any
Debtor.  All Proceeds of Collateral received by the Agent pursuant to this
Section may at the option of the Required Banks in the exercise of their
absolute discretion, (i) be applied by the Agent and the Banks to their
respective Obligations in such order and manner as they may elect in their
absolute discretion, or (ii) be deposited to the credit of any Debtor and held
as collateral for the Obligations or permitted to be used by such Debtor in the
ordinary course of its business.

     Section 5.1.   Power of Attorney.  Each Debtor hereby irrevocably
                    -----------------

power of substitution, as its true and lawful attorney-in-fact with full

     and the Debtors' expense, at any time, or from time to time, all acts and
     things which the Agent deems necessary to protect, preserve, or realize
     upon the Collateral and the Agent's security interest therein.

     This power of attorney is a power coupled with an interest and shall be
irrevocable.  The Agent shall be under no duty to exercise or withhold the
exercise of any of the rights, powers, privileges, and options expressly or
implicitly granted to the Agent in this Agreement, and shall not be liable for
any failure to do so or any delay in doing so.  The Agent shall not be liable
for any act or omission or for any error of judgment or any mistake of fact or
law in its individual capacity or in its capacity as attorney-in-fact except
acts or omissions resulting from its willful misconduct.  This power of attorney
is conferred on the Agent solely to protect, preserve, and realize upon its
security interest in the Collateral.  The Agent shall not be responsible for any
decline in the value of the Collateral and shall not be required to take any
steps to preserve rights against prior parties or to protect, preserve, or
maintain any security interest or Lien given to secure the Collateral.

     Section 5.2.   Setoff; Property Held by the Agents and the Banks.  If an
                    -------------------------------------------------
Event of Default shall have occurred and be continuing, the Agent, each Co-Agent
and each Bank shall have the right to set off and apply against the Obligations,
at any time and without notice to any Debtor, any and all deposits (general or
special, time or demand, provisional or final) or other sums at any time
credited by or owing from the Agent, any Co-Agent or any Bank to such Debtor
whether or not the

GUARANTOR SECURITY AGREEMENT - PAGE 11
<PAGE>

Obligations are then due. As additional security for the Obligations, each
Debtor hereby grants the Agent, each Co-Agent and each Bank a security interest
in all money, instruments, and other property of such Debtor now or hereafter
held by the Agent, any Co-Agent or any Bank, including without limitation,
property held in safekeeping. In addition to the Agent's, any Co-Agent's or any
Bank's right of setoff and as further security for the Obligations, each Debtor
hereby grants the Agent, each Co-Agent and each Bank a security interest in all
deposits (general or special, time or demand, provisional or final) of such
Debtor now or hereafter on deposit with or held by the Agent, any Co-Agent or
any Bank and all other sums at any time credited by or owing from the Agent, any
Co-Agent or any Bank to such Debtor. The rights and remedies of the Agent, each
Co-Agent and each Bank hereunder are in addition to other rights and remedies
(including, without limitation, other rights of setoff) which the Agent, any Co-
Agent or any Bank may have.

     Section 5.3.   Performance by the Agent.  If any Debtor shall fail to
                    ------------------------
perform any covenant or agreement contained in this Agreement, the Agent may
perform or attempt to perform such covenant or agreement on behalf of such
Debtor.  In such event, the Debtors shall, at the request of the Agent, promptly
pay any amount expended by the Agent in connection with such performance or
attempted performance to the Agent, together with interest thereon at the
Default Rate from and including the date of such expenditure to but excluding
the date such expenditure is paid in full. Notwithstanding the foregoing, it is
expressly agreed that the Agent shall not have any liability or responsibility
for the performance of any obligation of any Debtor under this Agreement.

     Section 5.4.   Subrogation.  If any of the Obligations are given in renewal
                    -----------
or extension or applied toward the payment of indebtedness secured by any Lien,
Agent, the Co-Agents and the Banks shall be, and are hereby, subrogated to all
of the rights, titles, interests and Liens securing the indebtedness so renewed,
extended, or paid.

     Section 5.5.   Agent's Duty of Care.  Other than the exercise of reasonable
                    --------------------
care and the physical custody of the Collateral while held by the Agent
hereunder, the Agent shall have no responsibility for or obligation or duty with
respect to all or any part of the Collateral or any matter or proceeding arising
out of or relating thereto, including without limitation any obligation or duty
to collect any sums due in respect thereof or to protect or preserve any rights
against prior parties or any other rights pertaining thereto, it being
understood and agreed that each Debtor shall be responsible for preservation of
all rights in the Collateral.  Without limiting the generality of the foregoing,
the Agent shall be conclusively deemed to have exercised reasonable care in the
custody of the Collateral if the Agent takes such action, for purposes of
preserving rights in the Collateral, as any Debtor may reasonably request in
writing, but no failure or omission or delay by the Agent in complying with any
such request by any Debtor, and no refusal by the Agent to comply with any such
request by any Debtor, shall be deemed to be a failure to exercise reasonable
care.

     Section 6.1.   Rights and Remedies.  If an Event of Default shall have
                    -------------------
occurred and be continuing, the Agent shall have the following rights and
remedies:

            (i)    In addition to all other rights and remedies granted to the
     Agent in this Agreement or in any other Loan Document or by applicable law,
     the Agent shall have all of the rights and remedies of a secured party
     under the UCC (whether or not the UCC applies to the affected Collateral).
     Without limiting the generality of the foregoing, the Agent may (1) without
     demand or notice to any Debtor, collect, receive, or take possession of the
     Collateral or any part thereof and for that purpose the Agent may enter
     upon any premises on which the Collateral is located and remove the
     Collateral therefrom or render it inoperable, and/or (2) sell, lease, or
     otherwise dispose of the Collateral, or any part thereof, in one or more
     parcels at public or private sale or sales, at the Agent's offices or
     elsewhere, for cash, on credit or for future delivery, and upon such other
     terms as the Agent may deem commercially reasonable.  The Agent shall have
     the right at any public sale or sales, and, to the extent permitted by
     applicable law, at any private sale or sales, to bid and become a purchaser
     of the Collateral or any part thereof free of any right or equity of
     redemption on the part of any Debtor, which right or equity of redemption
     is hereby expressly waived and released by each Debtor.  Upon the request
     of the Agent, each Debtor shall assemble the Collateral and make it
     available to the Agent at any place designated by the Agent that is
     reasonably convenient to such Debtor and the Agent.  Each Debtor agrees
     that the Agent shall not be obligated to give more than five days written
     notice of the time and place of any public sale or of the time after which
     any private sale may take place and that such notice shall constitute
     reasonable notice of such matters.  The Agent shall not be obligated to
     make any sale of Collateral if it shall determine not to do so, regardless
     of the fact that notice of sale of Collateral may have been given.  The
     Agent may, without notice or publication, adjourn any public or private
     sale or cause the same to be adjourned from time to time by announcement at
     the time and place fixed for sale, and such sale may, without further
     notice, be made at the time and place to which the same was so adjourned.
     The Debtors shall be jointly and severally liable for all expenses of
     retaking, holding, preparing for sale, or the like, and all attorneys'
     fees, legal expenses, and all other costs and expenses incurred by the
     Agent in connection with the collection of the Obligations and the
     enforcement of the Agent's rights under this Agreement.  The Debtors shall
     remain liable for any deficiency if the Proceeds of any sale or other
     disposition of the Collateral are insufficient to pay the Obligations in
     full.  The Agent, the Co-Agents and the Banks may apply the Collateral
     against the Obligations in such order and manner as the Agent may elect in
     its sole discretion.  Each Debtor waives all rights of marshalling,
     valuation, and appraisal in respect of the Collateral.

            (ii)   The Agent may cause any or all of the Collateral held by it
     to be transferred into the name of the Agent or the name or names of the
     Agent's nominee or nominees.

GUARANTOR SECURITY AGREEMENT - PAGE 13
<PAGE>

            (iii)  The Agent may collect or receive all money or property at any
     time payable or receivable on account of or in exchange for any of the
     Collateral, but shall be under no obligation to do so.

            (iv)   On any sale of the Collateral, the Agent is hereby authorized
     to comply with any limitation or restriction with which compliance is
     necessary, in the view of the Agent's counsel, in order to avoid any
     violation of applicable law or in order to obtain any required approval of
     the purchaser or purchasers by any applicable Governmental Authority.
