                  Notes to Consolidated Financial Statements
                                 (Unaudited)

(1)  Basis of Presentation
     ---------------------

     Although interim consolidated financial statements of CellStar Corporation
(the "Company" or "CellStar") are unaudited, it is the opinion of the Company's
management that all recurring adjustments necessary for a fair statement of the
results have been reflected therein. Operating revenues and net earnings for any
interim period are not necessarily indicative of the 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, 1995.

(2)  Geographic Area Information
     ---------------------------

     The Company operates predominately within one business segment, wholesale
and retail sales of cellular phones and related products and services. Financial
information by geographic area as of and for the nine months ended August 31,
1996 and 1995, is as follows (in thousands):

       ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                RESULTS OF OPERATIONS

       OVERVIEW

            The Company experienced a net loss of $12.3 million in the third
       fiscal quarter, primarily due to unusual expenses incurred in its South
       American operations. The South American loss was attributable to $14.9
       million of unusual expenses in the Company's South American operations,
       including an $8.5 million increase in trade accounts receivable reserves
       and a $2.0 million write-off of a deferred tax asset. See "International
       Operations" and "Provision for Income Taxes." In addition, the Company
       continued to experience unprofitable performance in its Communication
       Centers in Sam's Club locations. As reported earlier, the Company is
       continuing to strengthen its internal controls to reduce its exposure to
       financial and operating risks.

            The Company announced in April 1996 that it was encountering
       problems with its financial controls.  At that time, CellStar initiated a
       program to build stronger financial and information technology control
       systems. The initial focus has been on materials management,
       international operations and information technology.  The Company expects
       to see positive impact from these important steps by the end of fiscal
       year 1996.

            The Company primarily relies on cash generated from operations and
       borrowings under existing credit facilities to fund working capital,
       capital expenditures and expansions.  The Company believes that its
       current cash resources will be adequate to meet the Company's capital
       needs in the near term. The Company also believes that long-term capital
       will be required over time to allow the Company to grow and anticipates
       that such funding will be available.  See "Liquidity and Capital
       Resources."

            The Company has entered into a definitive agreement with MCI
       Telecommunications Corporation ("MCI") for the sale of the Company's
       Communication Centers located in Sam's Clubs for $17.2 million, subject
       to certain purchase price adjustments.  Under the terms of the agreement,
       MCI will purchase certain assets of the Communication Center operations,
       assume certain contracts used in connection with the operations and
       retain substantially all of the employees.  The Company will also sign a
       distribution agreement with MCI to supply MCI with cellular phones and
       accessories for the Communication Centers.  The Company expects to
       consummate this transaction by the end of fiscal year 1996.  The closing
       of the transaction is subject to certain conditions.  Accordingly, there
       can be no assurance that the transaction will be consummated.  The
       Company anticipates that this sale will enable it to focus its resources
       more effectively on its core wholesale business.

            Revenues.  Total revenues increased $25.3 million, or 12.8%, from
       $198.3 million in the third fiscal quarter of 1995 to $223.6 million in
       the third fiscal quarter of 1996.

            Domestic revenues increased $55.6 million, or 60.7%, from $91.6
       million to $147.2 million.  The increase in domestic revenues was due
       primarily to increased product sales from the Company's Miami, Florida
       warehouse to customers exporting into South American countries as the
       cellular capacity in those countries expanded.  In addition, the Company
       changed its business strategy to shift sales from its South American
       operations to the United States.  See "International Operations."  Also
       contributing to this increase was the Company's increased presence in the
       western United States market through its acquisition of 80% ownership in
       CellStar West, Inc. ("CellStar West") in February 1996.

            Domestic activation income increased $5.7 million primarily as a
       result of an overall increase in unit sales at the retail level, which
       was partially offset by a decrease in the average commission per
       activation paid by cellular carriers.  The increase in unit sales at the
       retail level was attributable to the Company's expansion of Communication
       Centers from an average of 219 to 354 Sam's Club locations for the three
       months ended August 31, 1995 and 1996, respectively.  The increase in
       residual income corresponds to the Company's growing cellular phone user
       base, which was partially offset by lower average monthly user phone
       bills.

            The Company's international revenues decreased 28.4% from $106.7
       million to $76.4 million.  Net product sales in the Company's Asia-
       Pacific operations declined $31.9 million, or 42.1%, from $75.7 million
       in 1995 to $43.8 million in 1996. This decline resulted from a lower
       level of net product sales in the Company's Hong Kong operations.  Net
       product sales in Hong Kong declined $34.3 million, from $65.3 million in
       1995 to $31.0 million in 1996, due to several factors including the
       unavailability of the highly popular digital PCS phones and increased
       competition that caused downward pressure on selling prices.  The
       decrease in net product sales in Hong Kong was somewhat offset by the
       Company's operations in Singapore, which generated $12.3 million of
       revenue in 1996, an 18.3% increase from $10.4 million in 1995.

            Net product sales in Mexico increased by approximately $4.3 million,
       or 95.6%, from $4.5 million in 1995 to $8.8 million in 1996.  This
       improvement was due to both an improvement in general economic conditions
       and the introduction of the lower cost prepaid cellular plans, which
       stimulated demand for cellular products.  However, the Company does not
       expect this trend to continue due to a change in market conditions, which
       may cause a reduction in net product sales.

            Net product sales in the Company's South American operations
       declined $1.2 million, or 6.1%, from $19.7 million in 1995 to $18.5
       million in 1996. This decline resulted from lower levels of net product
       sales in each of the Company's South American operations, with the
       exception of the Company's operations in Argentina and Ecuador, which
       commenced business in November 1995 and had combined net product sales of
       $5.4 million in 1996. See "International Operations." The largest
       declines in net product sales were experienced by the Company's
       operations in Venezuela, Colombia and Brazil. Net product sales in
       Venezuela declined by $3.2 million, or 72.7%, from $4.4 million in 1995
       to $1.2 million in 1996. This decrease in net product sales resulted from
       declining economic conditions in Venezuela and a major devaluation in the
       Venezuelan bolivar relative to the U.S. dollar during the second fiscal
       quarter of 1996. Net product sales in other South American countries were
       impacted by the Company's change in its business strategy to shift sales
       from its South American operations to the United States. Net product

                                       10
<PAGE>
 
       sales in Colombia declined $0.8 million, or 33.3%, from $2.4 million in
       1995 to $1.6 million in 1996. Net product sales in Brazil declined $2.4
       million, or 21.4%, from $11.2 million in 1995 to $8.8 million in 1996. 

            Gross Profit.  Gross profit as a percentage of total revenues
       decreased from 15.5% in the third quarter of fiscal year 1995 to 13.8% in
       the third quarter of fiscal year 1996 primarily due to an increase in the
       provision of $3.1 million for inventory obsolescence, principally related
       to the South American operations.

            Selling, General and Administrative Expenses.  Selling, general and
       administrative expenses increased $16.3 million, or 77.6%, from $21.0
       million to $37.3 million.  Approximately $8.5 million of the increase
       resulted from an increase in trade accounts receivable reserves to
       reflect a deterioration in the trade accounts receivable portfolio in the
       Company's South American operations, primarily in Brazil.  See
       "International Operations."  An additional $2.9 million, or 17.8%, of the
       increase was attributable to an increase in salaries and benefits for the
       addition of employees to support the growth of the Company's operations,
       primarily the expansion of Communication Centers from an average of 219
       to 354 Sam's Club locations for the three months ended August 31, 1995
       and 1996, respectively.  The expansion of Communication Centers also gave
       rise to other increases in selling, general and administrative expenses
       as these operations have experienced higher operating expenses than
       wholesale operations.

            Operating (Loss) Income.  Operating income decreased from $9.7
       million to a loss of $6.5 million primarily due to the significant
       increase in selling, general and administrative expenses and the
       reduction in net product sales in the Company's Asia-Pacific operations.

            Provision for Income Taxes.  Income tax expense increased from $1.7
       million in the third quarter of 1995 on pre-tax income of $7.9 million to
       $2.7 million in the third quarter of 1996 on a pre-tax loss of $9.6
       million.  At August 31, 1996, the Company wrote off a deferred tax asset
       of approximately $2.0 million associated with its Brazilian operation due
       to the uncertainty of the Company's ability to generate sufficient future
       taxable income to utilize this tax benefit in the near term. Further, for
       the same reason, the Company did not recognize a tax benefit associated
       with current period losses in its South American operations. See
       "International Operations."

       NINE MONTHS ENDED AUGUST 31, 1996 COMPARED TO NINE MONTHS ENDED AUGUST
       31, 1995

            Revenues.  Total revenues increased $87.2 million, or 15.4%, from
       $566.9 million in the nine-month period ended August 31, 1995 to $654.1
       million in the nine-month period ended August 31, 1996.

            Domestic revenues increased $19.4 million, or 5.3%, from $367.1
       million to $386.5 million.  The increase in domestic revenues was
       attributable to increased product demand and increases in activation and
       residual income.  Domestic net product sales decreased as a result of the
       acquisition of the remaining 50% interest in the Company's Hong Kong
       joint venture, CellStar (Asia) Corporation, Ltd. ("CellStar Asia"), in
       June 1995.  Sales of product to CellStar Asia, which were $90.2 million
       through the date of acquisition, were considered export sales within
       domestic operations. Net product sales for CellStar Asia for the nine
       months ended August 31, 1996 were included in international operations.
       The decrease in domestic product sales, which resulted from the
       acquisition of CellStar Asia, was offset by increased net product sales
       from the Company's Miami, Florida warehouse to customers exporting into
       South American countries as the cellular capacity in those countries
       expanded. In addition, the Company changed its business strategy to shift
       sales from its South American operations to the United States. See
       "International Operations." Also contributing to this increase was the
       Company's increased presence in the western United States market through
       its acquisition of 80% ownership in CellStar West in February 1996.

            Domestic activation income increased $20.2 million, primarily as a
       result of an overall increase in unit sales at the retail level, which
       was partially offset by a decrease in the average commission per
       activation paid by cellular carriers.  The increase in unit sales at the
       retail level was attributable to the Company's expansion of Communication
       Centers from an average of 154 to 352 Sam's Club locations for the nine
       months ended August 31, 1995 and 1996, respectively.  The increase in
       residual income corresponds to the Company's growing cellular phone user
       base.  The increase, however, was partially offset by lower average
       monthly user phone bills.

            The Company's international revenues increased 34.0%, from $199.8
       million to $267.7 million. The growth in international revenues was due
       primarily to the acquisition of the remaining 50% interest in CellStar
       Asia, which resulted in CellStar Asia's revenues being classified as
       international revenues beginning in June 1995. Prior to the acquisition,
       CellStar Asia's operations were not consolidated with the operations of
       the Company and sales to CellStar Asia were considered revenues of the
       Company's domestic operations. CellStar Asia provided $140.4 million in
       product revenues in the first three quarters of 1996 compared to $65.3
       million in 1995 subsequent to the acquisition. Sales of product to
       CellStar Asia in 1995, prior to the Company's acquisition of the
       remaining 50% interest, were $90.2 million and were included in domestic
       net product sales. The Company's operations in Singapore, which commenced
       in the first quarter of 1995, generated $32.6 million of revenue in 1996,
       a 63.8% increase from $19.9 million in 1995.

            Net product sales in Mexico decreased by approximately $0.8 million,
       or 3.5%, from $22.8 million in 1995 to $22.0 million in 1996.  This
       decline in net product sales in Mexico was primarily due to decreased
       demand for cellular products in Mexico that began in the second quarter
       of 1995 and continued through the first quarter of fiscal 1996.  The
       decline in demand was, in turn, caused in part by a large devaluation of
       the Mexican peso relative to the U.S. dollar in December 1994.  While net
       product sales in Mexico declined during the first nine months of 1996
       relative to the same period in 1995, net product sales during the third
       quarter of 1996 improved from the same period in 1995 due to an improved
       economy and the introduction of 

                                       12
<PAGE>
 
       lower cost prepaid cellular plans that stimulated demand for cellular
       products. However, the Company does not expect this trend to continue due
       to a change in market conditions, which may cause a reduction in net
       product sales.

            Net product sales in the Company's South American operations
       declined $14.8 million, or 20.4%, from $72.4 million in 1995 to $57.6
       million in 1996. This decline in net product sales resulted from lower
       levels of net product sales in each of the Company's South American
       operations, with the exception of the Company's operations in Argentina
       and Ecuador, which commenced business in November 1995 and had combined
       net product sales of $15.5 million in 1996. Net product sales were
       impacted by the Company's change in its business strategy to shift sales
       from its South American operations to the United States and by tighter
       credit controls imposed by the Company on its wholesale customers in
       South America. See "International Operations." The largest declines in
       net product sales in South America were experienced by the Company's
       operations in Colombia and Brazil. Net product sales in Colombia declined
       $11.6 million, or 55.8%, from $20.8 million in 1995 to $9.2 million in
       1996 due to the unavailability of product. Net product sales in Brazil
       declined by $11.0 million, or 30.4%, from $36.2 million in 1995 to $25.2
       million in 1996.

            Gross Profit.  Gross profit increased by $14.6 million, or 18.8%,
       from $77.8 million to $92.4 million, and gross profit as a percentage of
       total revenues increased from 13.7% in the nine-month period ended August
       31, 1995 to 14.1% in the current period.  Revenues for the nine-month
       period ended August 31, 1995 included export sales of $90.2 million, with
       a gross margin of 4.1%, to CellStar Asia, which became a wholly-owned
       subsidiary on June 2, 1995.  The increase in gross profit in 1996 was
       primarily due to the consolidation of CellStar Asia's higher gross margin
       sales and an increase in domestic retail sales relative to wholesale
       sales, which have a higher gross margin than wholesale domestic sales.
       Domestic retail revenues increased from $63.4 million to $101.6 million
       primarily due to the increase in the number of Communication Centers.
       These gross profit increases were partially offset by provisions for
       inventory obsolescence.
 
            Selling, General and Administrative Expenses.  Selling, general and
       administrative expenses increased $42.6 million, or 77.0%, from $55.3
       million to $97.9 million.  Approximately $11.2 million, or 26.3%, of the
       increase resulted from an increase in trade accounts receivable reserves
       to reflect a deterioration in the trade accounts receivable portfolio in
       the Company's South American operations, primarily in Brazil.  See
       "International Operations."  An additional $12.0 million, or 28.2%, of
       the increase was attributable to an increase in salaries and benefits for
       the addition of employees to support the growth of the Company's
       operations, primarily the expansion of Communication Centers from an
       average of 154 to 352 Sam's Club locations for the nine months ended
       August 31, 1995 and 1996, respectively.  The expansion of Communication
       Centers also gave rise to other increases in selling, general and
       administrative expenses as these operations have experienced higher
       operating expenses than wholesale operations.

            Operating (Loss) Income. Operating income decreased from $22.6
       million to a loss of $5.4 million due to the significant increase in
       selling, general and administrative expenses.

            Interest Expense.  Interest expense increased in the nine months
       ended August 31, 1996 to $6.9 million from $3.6 million in the nine
       months ended August 31, 1995.  The increase in interest expense resulted
       primarily from the maintenance of a higher balance under the Company's
       revolving credit agreements.

            Equity in Earnings (Undistributed Loss) of Joint Ventures.  Equity
       in earnings of joint ventures decreased $3.9 million from the nine months
       ended August 31, 1995 to the nine months ended August 31,  1996. The
       decrease was attributable to the Company's acquisition of the 

                                       13
<PAGE>
 
remaining 50% interest in CellStar Asia in June 1995.  The Company's 50% equity
interest in the operations of CellStar Asia prior to the date of the acquisition
was classified as equity in earnings of joint ventures.

     Provision for Income Taxes.  Income tax expense decreased from $5.7 million
in the nine months ended August 31, 1995 to $1.6 million in the nine months
ended August 31, 1996.  This change was primarily due to the net loss for the
period and the non-recognition of tax benefits related to current period losses
in the Company's South American operations.  See "International Operations."

                                      14

LIQUIDITY AND CAPITAL RESOURCES

     The Company primarily relies on cash generated from operations and
borrowings under its credit facilities to fund working capital, capital
expenditures and expansions. In addition, in certain situations, the Company has
been provided with extended terms from key suppliers to fund working capital
requirements of the domestic and Latin American operations.

     The Company's primary revolving credit facility (the "Credit Agreement") is
with a group of five banks and currently has a maximum borrowing limit of $90.0
million. Fundings under the line are limited by a borrowing base computed as a
percentage of domestic accounts receivable and inventories. At October 8, 1996,
the borrowing base limited borrowings to $79.2 million ($75.7 million at August
31, 1996).

     CellStar Asia has a $15.0 million credit agreement with a bank. Fundings
under this credit agreement are limited by a borrowing base computed as a
percentage of CellStar Asia's accounts receivable and inventories. At October 8,
1996, the borrowing base limited borrowings to $15.0 million ($14.2 million at
August 31, 1996).

     At August 31, 1996, the Company had $10.8 million of cash and cash
equivalents, a decrease of $20.7 million since November 30, 1995. This decrease
is reflective of a reduction of credit obligations and domestic and South
American operating losses. The Company reduced bank debt by $27.2 million during
the nine months ended August 31, 1996 by effectively managing inventory levels
downward by $15.6 million primarily in its domestic and South American
operations. On October 3, 1996, the Company announced it had signed an agreement
with MCI for the sale of the Company's Communication Centers. The Company
anticipates the sale will close by November 30, 1996. Proceeds from the sale
will be used to pay down the Credit Agreement and for working capital purposes.
The Company does not currently anticipate that it will need capital in excess of
its current credit facilities in the near future to fund its operations, capital
expenditures and near term business expansion.

     The Company has received extended credit terms from key suppliers. The
Company anticipates that such extended terms will continue to be made available
to the Company in certain situations and the Company will take advantage of the
extended terms to meet part of its short-term working capital needs. This
situation did not materially impact the Company's ability to obtain inventory
and thus did not have a significant impact on sales for the period.

     Cash used in investing activities of $4.0 million primarily related to
purchases of various computer and office equipment during the nine months ended
August 31, 1996. By comparison, the Company spent $7.2 million during the same
period in the last fiscal year for the construction of its distribution
warehouse in Carrollton, Texas and office equipment primarily for the expansion
of Communication Centers.

     Traditionally, CellStar has financed growth in its domestic business and
expansion into international markets with bank credit facilities. The Company
believes that long-term capital funding in the form of debt and/or equity will
be required over time to continue to allow the Company to grow. While CellStar
has no immediate plans for long-term debt and/or equity financing, it
anticipates that financing will be available at the appropriate time to meet the
Company's long-term capital needs.

INTERNATIONAL OPERATIONS

     The Company's South American operations were negatively impacted by several
factors during the third quarter, including a significant deterioration in the
trade accounts receivable portfolio, an increase in the provision for inventory
obsolescence and the write-off of a deferred tax asset. In recognition of the
deterioration of its trade accounts receivables portfolio in specific South
American markets, the Company added $8.5 million to its allowance for doubtful
accounts in the region. Two countries, Brazil and Colombia, were responsible for
a majority of this increase in the allowance, with the bankruptcy of one
Brazilian customer during September accounting for the addition of $3.3 million
to the allowance. While the Company believes that the level of its allowance is
adequate to cover the risks of loss it has currently identified in its trade
accounts receivable portfolio in South America, a further decline in economic
conditions in the region could have an adverse effect on the Company, including
the possible negative impact of such decline on a concentration of receivables
among relatively few customers in Brazil.

     At August 31, 1996, the Company wrote off a deferred tax asset of
approximately $2.0 million associated with its Brazilian operation due to the
uncertainty of the Company's ability to generate sufficient future taxable
income to utilize this tax benefit in the near term.

     During the third quarter, the Company continued its program to reduce the
overall level of assets maintained in South America. The intent of this program
is to reduce the Company's working capital requirements related to its South
American operations to reduce the Company's exposure to financial and operating
risks in the region. This program resulted in a $30.8 million, or 41.7%,
reduction in South American assets from $73.9 million at February 29, 1996, to
$43.1 million at August 31, 1996. Other changes to the Company's South American
business strategy include a trend toward selling product to certain large South
American customers directly from the Company's U.S. operations, where feasible,
and a general reduction in the number of employees in the region. The Company
expects this South American asset reduction trend to continue in subsequent
quarters, although at a somewhat slower pace than experienced in the second and
third quarters of 1996.

     As a result of economic volatility in Latin America, many currencies in the
region have consistently lost value relative to the U.S. dollar over time. This
regional history of local currency devaluations relative to the U.S. dollar
along with the Company's largely U.S. dollar based cost structure for its Latin
American operations produce the potential for the Company to incur foreign
currency transaction losses in the normal course of business. In the third
quarter of 1996, the Company experienced $0.7 million in foreign currency
transaction losses, primarily related to its operation in Brazil. The Company
attempts to mitigate the financial impact of foreign currency devaluations
relative to the U.S. dollar by pricing its products in U.S. dollars where
possible, by increasing prices of products at or above the anticipated rate of
local currency devaluations, by indexing certain of its local currency accounts
receivable to exchange rates in effect at the time of their payment, and by
entering into foreign currency hedge contracts in certain instances.

                          PART II - OTHER INFORMATION

       ITEM 1.  LEGAL PROCEEDINGS

            On July 22, 1996, a purported class action lawsuit was filed in the
       Northern District of Texas, Dallas Division, styled as follows:  Reed and
       Lillian Riemer v. CellStar Corporation, Alan H. Goldfield, Terry S.
       Parker, John S. Bain, Kenneth W. Sanders and KPMG Peat Marwick, L.L.P.
       (the "Riemer Suit").  The Riemer Suit alleges violations of Sections
       10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and
       Rule 10b-5 promulgated thereunder, as well as certain state laws.  The
       plaintiffs allege that the defendants made untrue statements of material
       fact and/or omitted to state material facts about the business, financial
       condition, performance and future prospects of the Company, and that the
       value of the Company's common stock was artificially inflated as a result
       of such statements and omissions.  The Riemer Suit seeks compensatory and
       exemplary damages and reimbursement of counsel and expert fees and costs.

            The Riemer Suit has been consolidated with the Gluck Suit, the
       Larson Suit, and the Goggin Suit discussed in the Form 10-Q for the
       quarterly period ended May 31, 1996, and the State of Wisconsin
       Investment Board has been appointed lead plaintiff in the consolidated
       action.

file all such reports and returns as may be required by Section 1060 of the Code

proratable items which are attributable to the Inventory and the Acquired Assets

included in the Purchase Price adjustment made pursuant to Section 3.7.  The

as true and correct and as having been prepared in accordance with the Sellers'
books and records.  The Purchase Price to be paid at Closing shall be adjusted
either upward or downward, as applicable, based on the amount of such

Buyer shall not pay such adjustment unless and until the Buyer shall have
verified and agreed to the amount of such upward adjustment, which verification
and agreement shall be made no later than five days prior to the Closing Date.
If the Buyer fails to so agree with any item in the Preliminary Statement
prepared by the Seller, then any items on which the Buyer has so failed to agree
shall remain open and be determined in conjunction with the preparation of the
Final Statement (as hereinafter defined).

Sellers shall notify the Buyer in writing of any disputed items contained in the
Assets Determination within thirty (30) days from its delivery, and after such

Price (the "Final Statement").

     As soon as practical, but in any event within thirty (30) days following
the Closing, the Sellers shall prepare and deliver to the Buyer an inventory
determination (the "Inventory Determination") comparing the cost of the
Inventory as of July 31, 1996, which is set forth in Schedule 2.3 hereto, with
                                                     ------------

Buyer may each conduct their own physical count of the Inventory transferred on
the Closing Date.  The Buyer shall notify the Sellers in writing of any disputed
items contained in the Inventory Determination within thirty (30) days from its
delivery, and after such date all undisputed items shall be deemed accepted by
the Buyer and made part of the Final Statement.

     In the event that the Sellers and the Buyer are unable to agree upon
disputed items within thirty (30) days after the Buyer's notification thereof,
then the amount of the disputed items shall be determined by the accounting firm
of Price Waterhouse LLP, or such other firm selected by the Buyer within fifteen
days after the end of such thirty day period.  The disputed items shall be
submitted to the selected accounting firm within thirty days after such
accounting firm is selected.  The determination by such accounting firm shall be
conclusive and binding on all parties, shall be made within sixty days after
such disputed items are so submitted and shall be made a part of the Final
Statement.  The Buyer shall pay all of the fees and expenses of the accounting
firm settling any disputed items on the Final Statement.

     3.7  Adjustment to Purchase Price.  In the event the Final Statement
          ----------------------------                                   
reflects an increase in the actual cost of the Inventory, the aggregate Book
Value of the Fixed Assets, the amount paid in Paid Time Off or the Advertising
Allowance, the Purchase Price shall be adjusted upward (i) on a dollar for
dollar basis for any increase in the cost of Inventory, Book Value of the Fixed
Assets, or amount paid in Paid Time Off, and (ii) one dollar for every two
dollar increase in Advertising Allowance.  In the event that the Final Statement
reflects a decrease in the actual cost of the Inventory, the aggregate Book
Value of the Fixed Assets, the amount paid in Paid Time Off or the Advertising
Allowance, the Purchase Price shall be adjusted downward (i) on a dollar for
dollar basis for any decrease in the cost of Inventory, Book Value of the Fixed
Assets, or amount paid in Paid Time Off, and (ii) one dollar for every two
dollar decrease in  Advertising Allowance.  If such adjustments result in a
balance due

the Sellers (after taking into account the amount of the upward or downward
adjustment to the Purchase Price made based on the Preliminary Statement), the
Buyer shall pay such balance to the Parent within fifteen days after the date of
determination of the Final Statement; provided, however, that in no event shall
                                      --------  -------

Thousand Dollars ($150,000) for any Purchase Price adjustments resulting from an
increase in the aggregate Book Value as of July 31, 1996, of the Fixed Assets
transferred on the Closing Date.  If such adjustment results in a balance due
the Buyer (after taking into account the amount of the upward or downward
adjustment to the Purchase Price made based on the Preliminary Statement), the
Sellers shall pay such balance to the Buyer within fifteen (15) days after the
date of determination of the Final Statement.

     3.8  Post Closing Payments.  The Buyer and the Sellers acknowledge and
          ---------------------

consideration on any receivable of the Buyer, the recipient shall forward such
receipts to the appropriate party on a weekly basis.  In addition, after the
Closing Date, (i) if invoices are received by the Buyer that are the

          of the Sellers arising under such Accord from and after the effective
          date of such assignment.

being untrue and incorrect in any material respect, or not being performed as
contemplated in this Agreement.

and firing of Employees in the Ordinary Course of Business, and (ii) any failure
of the Buyer or the Sellers, as the case may be, or any officer, director,
employee or agent thereof, to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it hereunder.

Buyer shall complete any filing that may be

such filing is required.  The Sellers and the Buyer shall diligently take (or
fully cooperate in the taking of) all actions, and provide any additional
information, required or reasonably requested in order to comply with the
requirements of the Hart-Scott-Rodino Act.  The Buyer shall pay  the Hart-Scott-

          damages were foreseeable. The Parties hereby agree to use their Best
          Efforts to mitigate any Damages for which they may seek indemnity
          under this Article 10.

               (D)  No Indemnified Party (as defined below) shall be entitled to
          indemnification pursuant to this Article 10 unless and until the
          amount of Damages due with respect to such claims exceeds, in the

          whereupon all amounts then or thereafter due (including, but not

writing shall be delivered pursuant to the notice provision of this Agreement

Party within ten (10) days of the indemnified party's delivery of any bills,
receipts, statements or other evidence of Damages, or (ii) give written notice
to the Indemnified Party that it contests such claim.  If the Indemnifying Party
contests such claim in good faith (a "Disputed Claim"), then the Indemnified
Party and Indemnifying Party will proceed in good faith to negotiate a
resolution of such dispute, and if no resolution is reached within thirty (30)
days after the receipt by the Indemnified Party of  the notice contesting the

          10.3  Third Party Claims.  The obligations and Liabilities of any of
                ------------------                                            
the Parties to this Agreement under Section 10.1 hereof with respect to all
items indemnified against in Section 10.1 and which are initiated by third
parties (the "Third Party Claims") will be subject to the following terms and
conditions:

               (A)  Upon receipt of written notice of any Third Party Claim
          asserted against, resulting from, imposed upon or incurred by the
          Indemnified Party, the Indemnifying Party will undertake the defense
          thereof by counsel of its own choosing, which counsel shall be
          reasonably satisfactory to the Indemnified Party; provided, however,
                                                            --------  -------
          that the Indemnified Party shall have the right at its own expense to
          participate in the defense thereof and to employ counsel at its own
          expense to assist in such defense; and provided, further, that if the
                                                 --------  -------
          Indemnified Party has been advised in writing by such counsel that a
          conflict of interest exists between such Indemnified Party and the
          Indemnifying Party with respect to such Third Party

                                       44
<PAGE>
 
          Claim, such Indemnified Party shall be entitled to select counsel of
          its own choosing, in which event the Indemnified Party shall be
          obligated to pay the reasonable fees and expenses of such counsel. In
          any such defense, the Indemnified Party shall have the right, but not
          the obligation, to assert any and all cross claims or counterclaims it
          may have. In case any Third Party Claim shall be instituted involving
          any Person in respect of which indemnity may sought pursuant to this
          Article 10, such Indemnified Party shall promptly notify the
          Indemnifying Party in writing of such proceeding. No indemnification
          provided for in Section 10.1 above shall be available to any Person
          who shall fail to promptly give notice of a Third Party Claim as
          provided in the immediately preceding sentence if the Person to whom
          such notice was not given was unaware of the Third Party Claim to
          which such notice would have related and was materially prejudiced by
          the failure to receive such notice.

               (B)  If within a reasonable time after written notice of any
          Third Party Claim, the Indemnifying Party fails to defend the
          Indemnified Party against whom such Third Party Claim has been
          asserted or shall fail to diligently prosecute such defense or
          compromise such claim, the Indemnified Party will have the right, with
          counsel of its own choice, at the Indemnifying Party's expense, to
          undertake the defense, compromise or settlement of such Third Party
          Claim on behalf of and for the account and at the risk of the
          Indemnifying Party.

               (C)  Nothing in this Section 10.3 to the contrary, the
          Indemnifying Party will not, without the prior written consent of each
          Indemnified Party against whom a Third Party Claim is asserted, settle
          or compromise, any claim or consent to the entry of any judgment
          relating to any such Third Party Claim, unless such settlement,
          compromise or judgment includes as an unconditional term thereof the
          giving by the claimant or the plaintiff to each Indemnified Party
          against whom a Third Party Claim is asserted, a release from all
          Liabilities in respect of such Third Party Claim and does not result
          in the imposition on the Indemnified Party of any remedy other than
          monetary damages up to the amount to be paid with respect to such
          claim by the Indemnifying Party pursuant to Section 10.1.

               (D)  The Indemnifying Party will, at its expense, provide each
          Indemnified Party against whom a Third Party Claim is asserted with
          reasonable access to all records and documents of the Indemnifying
          Party relating to any Third Party Claim. The Indemnified Party, at the
          expense of the Indemnifying Party, will provide the Indemnifying Party
          with reasonable access to all records and documents of the Indemnified
          Party relating to any Third Party Claim.

constitute a waiver or bar by any Party of any rights or remedies at law or in
equity they may have for damages caused by reason of a breach of this Agreement

at any time by the party that is entitled to the benefit thereof, but no such
waiver shall be effective unless set forth in a written instrument duly executed
by or on behalf of the party waiving such term or condition.  No waiver by any
Party of any term or condition of this Agreement, in any one or more instances,
shall be deemed to be or construed as a waiver of the same or any other term or

respective permitted successors or assigns, and

CONFIDENTIAL

                                       48

it is not the intention of the Parties to confer third-party beneficiary rights
upon any other person other than any person entitled to indemnity under this
Agreement.

          12.8  No Assignment, Binding Effect.  Neither this Agreement nor any
                -----------------------------                                 
right, interest or obligation hereunder may be assigned by any party hereto
without the prior written consent of the other Party hereto and any attempt to
do so will be void, except (i) for assignments and transfers by operation of
law, and (ii) that the Buyer may assign any or all of its rights, interests and
obligations hereunder to an Affiliate of the Buyer with the consent of the
Parent, which consent shall not unreasonably be withheld.  Subject to the

provisions hereof.

          12.10  Schedules, Exhibits and Other Agreements.  The Schedules,
                 ----------------------------------------                 
Exhibits, and other agreements specifically referred to in and delivered
pursuant to this Agreement are incorporated herein and shall be part of this
Agreement for all purposes.

          12.11  Severability.  In the event that any provision of this
                 ------------                                          
Agreement shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby, and this Agreement shall be construed as if such provision or
clause had never been contained in this Agreement, and there shall be deemed
substituted therefor such other provisions or clauses as will most nearly
accomplish the intent of the Parties expressed therein to the fullest extent
permitted by law.

          12.12  Governing Law.  Except as provided in Section 12.1, this

                 --------------------                                           
any breach of the terms of this Agreement may give rise to irreparable harm for
which money damages would not be an adequate remedy, and accordingly agree that,
in addition to other remedies any non-breaching party shall be entitled to
enforce the terms of this Agreement by a decree of specific performance without
the necessity of proving the inadequacy of money damages as a remedy.

          12.15  Construction of Certain Terms and Phrases.  Unless the content
                 -----------------------------------------

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


$________________                Dallas, Texas                     July 31, 1996


     FOR VALUE RECEIVED, the undersigned, NATIONAL AUTO CENTER, INC., a Texas
corporation ("Maker"), hereby promises to pay to the order of

___________________________  ("Payee"), at the offices of Texas Commerce Bank
National Association, as agent (together with any successor as provided in the
Agreement, hereinbelow defined, the "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 _____________________
DOLLARS ($_________), or so much thereof as may be advanced and outstanding
hereunder, together with interest as hereinafter specified.

     This Note is one of the Notes referred to in that certain Amended and
Restated Loan Agreement dated as of July 20, 1995, among Maker, CellStar
Corporation, a Delaware corporation, Payee, 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 amended by that
certain First Amendment to Amended and Restated Loan Agreement dated as of
February 29, 1996, and as further amended by that certain Second Amendment to
Amended and Restated Loan Agreement of even date herewith (such Amended and
Restated Loan Agreement, as the same has been and 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.

     This Note is in renewal and replacement of, but not extinguishment of, the
outstanding indebtedness evidenced by the existing promissory note previously
executed by Maker pursuant to the Agreement and payable to the order of Payee in
the stated amount of Payee's Commitment, which existing promissory note was
given in partial renewal, extension, modification and rearrangement of, but not
extinguishment of, the outstanding indebtedness of Maker under the Existing Loan
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
<PAGE>
 
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 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 2.4 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 shall be computed on the basis of a
year of 360 days and the actual number of days elapsed, and 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

PROMISSORY NOTE - Page 2

for payment, protest, notice of protest and non-payment or dishonor, notice of
acceleration, notice of intent to accelerate, notice of intent to demand,
diligence in collecting, 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.

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

     Section 2.2.   Renewal of Obligations and Liens.  The parties hereto
                    --------------------------------              
acknowledge and agree that (i) the Obligations are in part in renewal,
extension, modification and rearrangement of, but not extinguishment of, the
Existing Indebtedness, and (ii) the Existing Indebtedness is secured by liens
and security interests granted by the Debtor pursuant to the Original Security
Agreement and the Existing Security Agreement, which liens and security
interests are not extinguished or released, but instead are hereby renewed,
extended, carried forward and continued in accordance with the terms of this
Agreement.

     Section 2.3.   Debtor Remains Liable.  Notwithstanding anything to the 
                    ---------------------

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.

     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

pursuant to the Original Security Agreement, the Existing Security Agreement,
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 (5) 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 
                    ---------------------------

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, and ratifies and confirms the existing security interest granted
pursuant to the Original Security Agreement and the Existing Security Agreement,
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

     Section 4.1.   Encumbrances.  The Debtor shall not create, permit, or
                    ------------                                          
suffer to exist, and shall defend the Collateral against, any Lien on the

     Section 4.2.   Modification of Accounts.  The Debtor shall, in accordance
                    ------------------------

option with respect to, the Collateral or any part thereof without the prior
written consent of the Agent, except as expressly permitted by the Loan

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

documents and take such further action as the Agent may deem necessary or

negotiable documents of title) evidencing Inventory or Equipment; (c) deliver
and pledge to the Agent all Instruments and Chattel Paper of the Debtor with any

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 Debtor 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
Debtor shall reimburse the Agent for all costs and expenses incurred by the
Agent in obtaining such insurance. All such insurance shall provide that no

thereof. The Debtor shall deliver to the Agent and each Bank copies of all
insurance policies required by this Agreement.

Bank and their respective representatives to examine, inspect, and audit the

each location of Inventory having an aggregate value of $100,000 or more, as
specified on Schedule 1 hereto, except as hereinafter provided, the Debtor shall
cause each mortgagee of real property owned by the Debtor and each landlord of
real property leased by the 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 or
subordinates to the Agent's satisfaction its rights, if any, in the Collateral
(each, a "Landlord's Agreement"); provided, however that with respect to
                                  --------  -------                     
Collateral located at 8728 Westpark Drive, Houston, Texas, Debtor shall exert
its best efforts to obtain a Landlord's Agreement, but Debtor's failure to
obtain such a Landlord's Agreement with respect to such location shall not cause
the Inventory located at such location to be excluded from the Borrowing Base if
such Inventory otherwise constitutes Eligible Inventory.  After the date hereof,
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

identity, or corporate structure in any manner that might make any financing
statement filed in connection with this Agreement seriously misleading unless
the Debtor shall have given the Agent thirty (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. The Debtor
shall not 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
thirty (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 Debtor shall keep

business and financial condition in accordance with GAAP. The Debtor shall from
time to time at the request of the Agent deliver to the Agent such information
regarding the Collateral and the 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. The 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 Debtor shall keep the Equipment and Inventory at the

     more, the Debtor shall have given the Agent thirty (30) days prior written
     notice of the transfer of Equipment or Inventory to or opening of such
     location, and all action required to perfect the Agent's security interest
     in such Equipment and Inventory with the priority required by this
     Agreement shall have been taken, (ii) the Debtor shall deliver to the Agent
     by the twenty-fifth (25th) day of each month a computer listing of all
     locations of Equipment and Inventory not specified on Schedule 1 hereto or
     any listing previously delivered hereunder, and (iii) the Debtor shall take
     or cause to be taken all action necessary to perfect, with the same

          (b)  The Debtor shall maintain the Equipment and Inventory in good
     condition and repair (ordinary wear and tear excepted). The Debtor shall
     not permit any waste or destruction of the Equipment or Inventory or any
     part thereof. The Debtor shall not permit the Equipment or Inventory to be
     used in violation of any law, rule, or regulation or inconsistently with

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

law), except for any negotiable warehouse receipts issued for inventory in a
bonded warehouse facility in a foreign trade zone listed on Schedule 1.

     Section 4.12.  Notification.  The Debtor shall promptly, and in any event
                    ------------

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
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 Debtor shall have
irrevocably instructed such other bank (and such other bank shall have agreed)
to remit all such payments directly to the Agent, for the pro rata benefit of
the Banks. 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

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.

     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

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-

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.

Event of Default shall have occurred and be continuing, the 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 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 and each Bank a security interest in all money, instruments, and other
property of the Debtor now or hereafter held by the Agent or any Bank, including
without limitation, property held in safekeeping. In addition to the Agent's or
any Bank's right of setoff and as further security for the Obligations, the
Debtor hereby grants the 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 

AMENDED AND RESTATED SECURITY AGREEMENT - PAGE 13

on deposit with or held by the Agent or any Bank and all other sums at any time
credited by or owing from the Agent or any Bank to the Debtor. The rights and
remedies of the Agent and each Bank hereunder are in addition to other rights
and remedies (including, without limitation, other rights of setoff) which the
Agent or any Bank may have.

     Section 5.3.   Performance by the Agent.  If the 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 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 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
                    --------------------
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.


                                  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 

AMENDED AND RESTATED SECURITY AGREEMENT - PAGE 14
<PAGE>
 
     applies to the affected Collateral). Without limiting the generality of the
     foregoing, the Agent may (A) 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 (B) 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 (5) 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 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 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 

AMENDED AND RESTATED SECURITY AGREEMENT - PAGE 15

     any required approval of the purchaser or purchasers by any applicable
     Governmental Authority.

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

                    -----------------                                        
payment and performance in full when due of the Obligations (whether at stated
maturity, by acceleration, or otherwise), the Debtor hereby grants, and ratifies
and confirms the prior grant made pursuant to the Original Security Agreement

right, title, and interest in and to the following, whether now owned or

extension, modification and rearrangement of, but not extinguishment of, the

and security interests granted by the Debtor pursuant to the Original Security

interests are not extinguished or released, but instead are hereby renewed,
extended, carried forward and continued in accordance with the terms of this
Agreement.

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

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

     To induce the Agent to enter into this Agreement and the Agent and the
Banks to enter into the Loan 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

     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 the Original Security Agreement, the Existing Security Agreement,
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 (5) 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 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, and ratifies and confirms the existing security interest granted
pursuant to the Original Security Agreement and the Existing Security Agreement,
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

AMENDED AND RESTATED SECURITY AGREEMENT - Page 7
<PAGE>
 
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.

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

AMENDED AND RESTATED SECURITY AGREEMENT - Page 10

effect in any relevant jurisdiction or under relevant law).

     Section 4.12  Notification.  The Debtor shall promptly, and in any event
                   ------------

this Section, the Debtor shall have the right to collect and receive payments on
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
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 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 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.

     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 Collateral; (C) after the occurrence and

     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 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 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
that any failure by the Agent to so notify Debtor 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 5.2  Setoff; Property Held by the Agent and the Banks.  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 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 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 and each Bank a security interest in all money, instruments, and other
property of the Debtor now or hereafter held by the Agent or any Bank, including
without limitation, property held in safekeeping.  In addition to the Agent's or
any Bank's right of setoff and as further security for the Obligations, the
Debtor hereby grants the 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 or any Bank and all other sums at
any time credited by or owing from the Agent or any Bank to the Debtor.  The

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  

AMENDED AND RESTATED SECURITY AGREEMENT - Page 13

Rate from and including the date of such expenditure to but excluding the date

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
                  -----------

the 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 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

AMENDED AND RESTATED SECURITY AGREEMENT - Page 14
<PAGE>
 
     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 (5) 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 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 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.

interests are not extinguished or released, but instead are hereby renewed,
extended, carried forward and continued in accordance with the terms of this
Agreement.

     Section 2.3   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.

liability and obligation and the Borrower's entering into the Loan Agreement and
the Second Amendment have benefited and may reasonably be expected to benefit
the Debtor directly and indirectly.  Reference is hereby made to the Guaranty of

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 Debtor 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 Debtor shall 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

respect to Collateral located at 8728 Westpark Drive, Houston, Texas, Debtor
shall exert its best efforts to obtain a Landlord's Agreement, but Debtor's
failure to obtain such a Landlord's Agreement with respect to such location
shall not cause the Inventory located at such location to be excluded from the
Borrowing Base if such Inventory otherwise constitutes Eligible Inventory.
After the date hereof, 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

that might make any financing statement filed in connection with this Agreement
seriously misleading unless the Debtor shall have given the Agent thirty (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.  The Debtor shall not change its principal place of
business, chief executive office, or the place where it keeps its books and

time to time at the request of the Agent deliver to the Agent such information
regarding the Collateral and the 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.  The Debtor shall mark its books and
records to reflect the security interest of the Agent under this Agreement.

     of $100,000 or more.

          (b)  The Debtor shall maintain the Equipment and Inventory in

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

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

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

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

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.

     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

other sums at any time credited by or owing from the 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 and each
Bank a security interest in all money, instruments, and other property of
the Debtor now or hereafter held by the Agent or any Bank, including
without limitation, property held in safekeeping. In addition to the
Agent's or any Bank's right of setoff and as further security for the
Obligations, the Debtor hereby grants the 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 or any Bank and all other sums at any time credited by or owing from

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

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

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.

by any Lien, the 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 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.

                  -------------------                                    
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 (5) 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 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 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.

reorganization, or similar proceedings involving the Borrower. 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

extension, modification and rearrangement of, but not extinguishment of, the
Existing Indebtedness, and (ii) the Existing Indebtedness is secured by liens

                    -----                                     
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.

                    --------                                        
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

is on file in any public office, except those filed in favor of the Agent
pursuant to the Original Security Agreement, the Existing Security Agreement,
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 (5) 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
                    ----------------------

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, and ratifies and confirms the existing security interest granted
pursuant to the Original Security Agreement and the Existing Security Agreement,
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

perfection is not required under Section 4.10(a) hereof), subject to no equal or
prior Lien, except the Permitted Liens.

and to be received by the Debtor as a result of the Borrower, the Parent, the
Agent and the Banks entering into the Loan Agreement and the Second Amendment
and the Debtor executing and delivering this Agreement is reasonably worth at
least as much as the liability and obligation of the Debtor hereunder, and such
liability and obligation and the Borrower's entering into the Loan Agreement and
the Second Amendment have benefited and may reasonably be expected to benefit
the Debtor directly and indirectly. Reference is hereby made to the Guaranty of
the Debtor for a more complete description of the value and consideration
received and to be received by the Debtor in connection with the execution and
delivery of this Agreement and such Guaranty.

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

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 Debtor 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
Debtor shall 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

Agent by which such mortgagee or landlord waives its rights, if any, in the
Collateral (each, a "Landlord's Agreement"); provided, however, that with 
                                             --------  -------      
respect to Collateral located at 8728 Westpark Drive, Houston, Texas, Debtor
shall exert its best efforts to obtain a Landlord's Agreement, but Debtor's
failure to obtain such a Landlord's Agreement with respect to such location
shall not cause the Inventory located at such location to be excluded from the
Borrowing Base if such Inventory otherwise constitutes Eligible Inventory. After
the date hereof, 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

benefit of the Banks (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 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

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

held as collateral for the Obligations or permitted to be used by Debtor in the
ordinary course of its business.

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
that any failure by the Agent to so notify Debtor 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 5.2    Setoff; Property Held by the Agent and the Banks.  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 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 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 and each Bank a security interest in all money, instruments, and other
property of the Debtor now or hereafter held by the Agent or any Bank, including
without limitation, property held in safekeeping. In addition to the Agent's or
any Bank's right of setoff and as further security for the Obligations, the
Debtor hereby grants the 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 or any Bank and all other sums at
any time credited by or owing from the Agent or any Bank to the Debtor. The
rights and remedies of the Agent and each Bank hereunder are in addition to
other rights and remedies (including, without limitation, other rights of
setoff) which the Agent or any Bank may have.

     Section 5.3    Performance by the Agent.  If the 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 the
Debtor. In such event, the Debtor shall, at the request 

AMENDED AND RESTATED SECURITY AGREEMENT - Page 13
<PAGE>
 
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 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.

                                  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 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

AMENDED AND RESTATED SECURITY AGREEMENT - Page 14
<PAGE>
 
     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
     (5) 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 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 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.


                                 ARTICLE VII

                                 Miscellaneous

     releases as the Agent may deem appropriate; (G) to exchange any of the
     Collateral for other property upon any merger, consolidation,
     reorganization, recapitalization, or other readjustment of any issuer of
     Collateral and, in connection therewith, 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

     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 for any
purpose not inconsistent with the terms of this Agreement or the Loan 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 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 Loan Agreement, except as provided in Section 3.4 hereof.

     Section 4.4.   Setoff; Property Held by Agent and the Banks.  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 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 or any Bank to
Pledgor whether or not the Obligations are then due. As additional security for
the Obligations, Pledgor hereby grants the Agent and each Bank a security
interest in all money, instruments, and other property of Pledgor now or
hereafter held by the Agent or any Bank, including, without limitation, property
held in safekeeping. In addition to the Agent's or any Bank's right of setoff
and as further security for the Obligations, Pledgor hereby grants the 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 or any Bank and all other sums at any time
credited by or owing from the Agent or any Bank to Pledgor. The rights and
remedies of the Agent and each Bank hereunder are in addition to other rights
and remedies (including, without limitation, other rights of setoff) which the
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:

AMENDED AND RESTATED PLEDGE AGREEMENT - Page 10
<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 (5) 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 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.

AMENDED AND RESTATED PLEDGE AGREEMENT - Page 11
<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
     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.

          (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

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 are cumulative

     D.  Borrower, Parent and the Partnerships heretofore entered into that
certain Amended and Restated Contribution and Indemnification Agreement dated as
of July 20, 1995 (the "Existing Agreement"), to effect an equitable sharing of
their risk in respect of the Guaranteed Indebtedness.

     E.  The parties hereto desire to amend the Existing Agreement to add each
of the New Guarantors as a party thereto and have agreed, for purposes of
clarity and ease of administration, to carry out the agreed upon amendments by
amending the pertinent provisions of the Existing Agreement and then restating
the Existing Agreement in its entirety by means of this Agreement.

                              A G R E E M E N T:
                              - - - - - - - - - 

     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, and the Existing Agreement is
hereby amended and restated in its entirety as follows:

     1.  Capitalized terms used in this Agreement to the extent not otherwise
defined herein shall have the same meanings as in the Loan Agreement.   The
Companies other than Borrower shall be referred to herein collectively as the
"Subsidiary Guarantors" and each as a "Subsidiary Guarantor."

     2.  If any Subsidiary 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 Parent, and shall
be indemnified as set forth below; provided that no Subsidiary 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 Subsidiary 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 Subsidiary Guarantor making such payment shall have
the right to receive from each of the other Companies, and the other Companies
jointly and severally agree to pay to such Subsidiary Guarantor, when permitted
by paragraph 2 hereof, an amount such that the net payments made by the
Companies in respect of the Guaranteed Indebtedness shall be shared among the
Companies pro rata in proportion to their respective Pro Rata Percentages of the
Guaranteed Indebtedness.  The Companies hereby jointly and severally indemnify
each of the Subsidiary Guarantors and jointly and severally agree to hold each
of them harmless from and against any and all amounts which any such Subsidiary
Guarantor shall ever be required to pay in respect of the Guaranteed
Indebtedness in excess of such Subsidiary Guarantor's respective Pro Rata
Percentage of the Guaranteed Indebtedness.  Notwithstanding anything to the
contrary contained in this paragraph or in this Agreement, no

AMENDED AND RESTATED CONTRIBUTION AND
INDEMNIFICATION AGREEMENT - Page 2
<PAGE>
 
liability or obligation of any Company 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 Company, the percentage derived by dividing (a) the amount by which the
fair saleable value of its assets on May 31, 1996 exceeds its liabilities
(without giving effect to its Guaranty) (such excess for each Company, its "Net
Worth"), by (b) the Net Worth of all of the Companies.

     4.  If any Subsidiary Guarantor makes any payment in respect of the
Guaranteed Indebtedness, the Subsidiary Guarantor making such payment shall have
the right to receive from the Parent, and the Parent agrees to pay to such
Subsidiary Guarantor, when permitted by paragraph 2 hereof, an amount equal to
such payment.  The Parent hereby indemnifies each of the Subsidiary Guarantors
and agrees to hold each of them harmless from and against any and all amounts
which any such Subsidiary 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 Parent
that shall accrue pursuant to this Agreement shall be paid or shall be deemed
owed pursuant to this Agreement or any Loan Documents unless and until all of
the Guaranteed Indebtedness shall be paid in full.

     5.  Each party hereto represents and warrants to each other party hereto
and to their respective successors and assigns that:

          (a) the execution, delivery and performance by each party hereto of
     this Agreement are within such party's corporate or partnership powers,
     have been duly authorized by all necessary corporate or partnership action,
     as the case may be, require no action by or in respect of, or filing with,
     any governmental body, agency or official and do not contravene, or
     constitute a default under, any provision of applicable law or regulation
     or of the articles or certificate of incorporation or bylaws or other
     organizing document of such party or of any agreement, judgment,
     injunction, order, decree or other instrument binding upon such party or
     result in the creation or imposition of any lien, security interest or
     other charge or encumbrance on any asset of such party;

          (b) this Agreement constitutes a legal, valid and binding agreement of
     each party hereto, enforceable against such party in accordance with its
     terms; and

          (c) such party has adequate capital to conduct its business as a going
     concern, as presently conducted and as proposed to be conducted, 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, 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 party's internal projections and forecasts.

     6.  No failure or delay by any Company 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
provided by law.

     7.  Any provision of this Agreement may be amended or waived if, but only
if, such amendment or waiver is in writing and is signed by the parties hereto
and consented to by the Agent.

     8.  The provisions of this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns.

     9.  THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF TEXAS.

     10. This Agreement may be signed in any number of counterparts, each of
which shall be an original, with the same effect as if the signatures thereto
and hereto were upon the same instrument. This Agreement shall become effective
when a counterpart hereof shall have been signed by all the parties hereto.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.

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), 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

                                      -4-

          (b)  all Chattel Paper;

          (c)  all Instruments;

          (d)  all General Intangibles;

     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 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.  If the grant, 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 effective to the extent allowed by
Section 9.318 of the UCC or other applicable law but is otherwise limited by
that prohibition.

     Section 2.2.   Debtors Remain Liable.  Notwithstanding anything to the
                    ---------------------                                  
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 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 any Debtor thereunder or to take any
action to collect or enforce any claim for payment assigned hereunder.

     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 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 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 (5) 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 each Debtor, and the office where each
Debtor keeps its books and records, is located at the address specified below
the name of such Debtor on the signature pages hereof.

     Section 3.5.  Location of Collateral.  All Inventory and Equipment of
                   ----------------------                                 
each Debtor are located at the places specified on Schedule 1 hereto.  Each
Debtor has exclusive possession and control of its Inventory and Equipment.
None of the Inventory or Equipment of any Debtor is evidenced by a Document
(including, without limitation, a negotiable document of title).  All
Instruments and Chattel Paper of each Debtor 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 each Debtor, the security interest in favor of the Agent created
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.

                   ------------------                                 
received and to be received by each Debtor as a result of the Borrower, the
Parent, the Agent and the Banks entering into and obtaining credit under the
Loan Agreement and the Second Amendment 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 Loan Agreement and the
Second Amendment have benefited and may reasonably be expected to benefit each
Debtor directly and indirectly.

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

                   ------------------------                        
accordance with prudent business practices, endeavor to collect or cause to be

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

the Accounts for less than the full amount thereof, except for compromise,
compound or settlement in the ordinary course of business of Accounts not

option with respect to, the Collateral or any part thereof without the prior
written consent of the Agent, except as expressly permitted by the Loan

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

and amendments thereto, 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

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
thirty (30) days prior written notice thereof.  The Debtors shall deliver to the
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 Bank and their respective representatives to examine, inspect, and audit
the Collateral and to examine, inspect, and copy such Debtor's books and records
at 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

                                      -8-
<PAGE>
 
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");
provided, however that CellStar West, Inc. shall exert its best efforts to cause
CPD, Inc. and each landlord of the location at 31035 Genstar Road, Hayward,
California 94544, to execute and deliver to the Agent, on or before September
30, 1996, Landlord's Agreements (or a similar agreement with respect to CPD,
Inc.). 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 thirty (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
thirty (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.

     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 thirty (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

                                      -9-
<PAGE>
 
     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 (5) 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
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
                   -----------------                                 
constitutes and appoints the Agent and any officer or agent thereof, with full
power of substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the name of such Debtor or in its 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, each Debtor hereby gives the Agent the power and
right on behalf of such Debtor and in its own name to do any of the following,
without notice to or the consent of such Debtor and whether or not an Event of
Default has occurred and is continuing (except as otherwise expressly provided
below).

          (i)   after the occurrence and during the continuance of an Event of
     Default, to demand, sue for, collect, or receive in the name of any Debtor
     or in its own name, any money or property at any time payable or receivable
     on account of or in exchange for any of the Collateral and, in connection
     therewith, endorse checks, notes, drafts, acceptances, money orders,
     documents of title, or any other instruments for the payment of money under
     the Collateral or any policy of insurance;

          (ii)   to pay or discharge taxes or Liens levied or placed on or
     threatened against the Collateral;

          (iii)  after the occurrence and during the continuance of an Event of
     Default, to notify post office authorities to change the address for
     delivery of mail of any Debtor to an address designated by the Agent and to
     receive, open, and dispose of mail addressed to any Debtor;

          (iv)   (A) after the occurrence and during the continuance of an Event
     of Default, to direct account debtors and any other parties liable for any
     payment under any of the Collateral to make payment of any and all monies
     due and to become due thereunder 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 Collateral; (C) after the occurrence and during the
     continuance of an Event of Default, to sign and endorse any invoices,

     after the occurrence and during the continuance of an Event of Default, to
     settle, compromise, or adjust any suit, action, or proceeding described
     above and, in connection therewith, to give such discharges or releases as
     the Agent may deem appropriate; (G) to exchange any of the Collateral for
     other property upon any merger, consolidation, reorganization,
     recapitalization, or other readjustment of the issuer thereof and, in
     connection therewith, 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; (I) to renew,
     extend, or otherwise change the terms and conditions of any of the
     Collateral; (J) to make, settle, compromise, or adjust claims under any

     occurrence and during the continuance of an Event of Default, to sell,

     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 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 Agent and the Banks. 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 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 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 and each Bank a security interest in all money, instruments, and other
property of such Debtor now or hereafter held by the Agent or any Bank,
including without limitation, property held in safekeeping. In addition to the
Agent's or any Bank's right of setoff and as further security for the
Obligations, each Debtor hereby grants the 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 or
any Bank and all other sums at any time credited by or owing from the Agent or
any Bank to such Debtor. The rights and remedies of

                                     -12-
<PAGE>
 
the Agent and each Bank hereunder are in addition to other rights and remedies
(including, without limitation, other rights of setoff) which the 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 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

                                     -13-
<PAGE>
 
     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 (5) 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 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
     the purchaser or purchasers by any applicable Governmental Authority.

              (g)   All products, proceeds, revenues, distributions, dividends,
                    stock dividends, securities, and other property, rights, and

confirmed hereby is to secure the payment or performance of the following

them, to the Agent, now existing or hereafter arising (all of such obligations,
indebtedness, and liabilities being hereinafter sometimes called the

      the Banks in the aggregate principal amount of $90,000,000.00;

              (b)   the indebtedness, liabilities and obligations of the Pledgor

      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 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.

                                 ARTICLE II

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

Pledgor represents and warrants to the Agent that:

          
      Section 2.1.  Title.  Pledgor owns, and with respect to Collateral
                    -----                                               
acquired after the date hereof, Pledgor will own, legally and beneficially, the
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, except for the security interest granted hereunder.  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.

      Section 2.2.  Financing Statements. No financing statement covering any of
                    --------------------
the Collateral or its proceeds, except financing statements naming the Agent as
secured party, is on file in any public office. So long as any amount remains
unpaid on any Obligations or the Agent has any Commitment, Pledgor will not
execute or file, or consent to or permit the filing of, any such financing
statement or statements in any public office, except the financing statement
filed or to be filed with respect to the security interest hereby granted.

      Section 2.3.  Principal Place of Business.  The principal place of
                    ---------------------------                         
business and chief executive office of Pledgor, and the office where Pledgor
keeps its books and records, is located at the address of Pledgor shown at the
beginning of this Agreement.

      Section 2.4.  Percentage of Stock.  The shares of capital stock
                    -------------------                              
included in the Collateral constitute one hundred percent (100%) of the issued
and outstanding shares of capital stock of the Borrower and CAS.

      Section 2.5.  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 2.6.  Benefit to Pledgor.  The value of the consideration
                    ------------------                                 
received and to be received by the Pledgor as a result of the Borrower, the
Pledgor, the Agent and the Banks entering into the Loan Agreement and the Second
Amendment 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 and the Borrower's entering into the Loan
Agreement and the Second Amendment have benefitted and may reasonably be
expected to benefit the Pledgor directly and indirectly.

                                 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
identified in subsections (a) and (b) of Section 1.2 hereof and all other
certificates evidencing any other Collateral existing on the date hereof,
accompanied by undated stock powers 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
except the Permitted Liens, and shall defend Pledgor's rights in the Collateral
and the Agent's security interest in the Collateral against the claims and
demands of all Persons. Pledgor shall do nothing to impair the rights of the
Agent in the Collateral.

      Section 3.3.  Disposition of Collateral. Pledgor shall not sell, assign
                    -------------------------
(by operation of law or otherwise), or otherwise dispose of, or grant any option
with respect to the Collateral or any part thereof without the prior written
consent of the Agent.

      Section 3.4.  Distributions. If Pledgor shall become entitled to receive
                    ------------- 
or shall receive any stock certificate (including, without limitation, any
certificate representing a stock dividend or a distribution in connection with
any reclassification, increase, or reduction of capital or issued in connection
with any reorganization), option or rights, whether as an addition to, in
substitution of, or in exchange for any Collateral or otherwise, Pledgor agrees
to accept the same as the Agent's agent and to hold the same in trust for the
Agent, and to deliver the same forthwith to the Agent in the exact form
received, with the appropriate endorsement of Pledgor when necessary and/or
appropriate undated stock powers duly executed in blank, to be held by the Agent
as additional Collateral for the Obligations, subject to the terms hereof. Any
sums paid upon or in respect of the Collateral upon the liquidation, dissolution
or winding up of any issuer of Collateral shall be paid over to the Agent to be
held by it as additional Collateral for the Obligations subject to the terms
hereof; and in case any distribution of capital shall be made on or in respect
of the Collateral or any property shall be distributed upon or with respect to
the Collateral pursuant to any recapitalization or reclassification of the
capital of any issuer of Collateral or pursuant to any reorganization of any
issuer of Collateral, the property so distributed shall be delivered to the
Agent to be held by it, as additional Collateral for the Obligations, subject to
the terms hereof. All sums of money and property so paid or distributed in
respect of the Collateral that are received by Pledgor shall, until paid or
delivered to the Agent, be held by Pledgor in trust as additional security for
the Obligations.

      Section 3.5.  Further Assurances. At any time and from time to time, upon
                    ------------------
the request of the Agent, and at the sole expense of Pledgor, Pledgor shall
promptly execute and deliver all such further instruments 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, including, without limitation, the execution and

PLEDGE AGREEMENT - Page 5
<PAGE>
 
filing of such financing statements as the Agent may require.  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. Subject to the
right of Pledgor to receive cash dividends and distributions under Section 4.3
hereof, in the event any Collateral is ever received by Pledgor, Pledgor shall
promptly transfer and deliver to the Agent such Collateral so received by
Pledgor (together with any necessary endorsements in blank or undated stock
powers duly executed in blank), which Collateral shall thereafter be held by the
Agent pursuant to the terms of this Agreement.  The Agent shall at all times
have the right to exchange any certificates representing Collateral for
certificates of smaller or larger denominations for any purpose consistent with
this Agreement.

      Section 3.6.  Inspection Rights. Pledgor shall permit the Agent and its
                    -----------------
representatives to examine, inspect, and copy Pledgor's books and records at any
reasonable time and as often as the Agent may desire during normal business
hours.

      Section 3.7.  Notification. Pledgor shall promptly, and in any event
                    ------------
within five (5) days after Pledgor 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 3.8.  Books and Records; Information.  Pledgor shall keep
                    ------------------------------                     
accurate and complete books and records of the Collateral and Pledgor's business
and financial condition in accordance with GAAP.  Pledgor shall from time to
time at the request of the Agent deliver to the Agent such information regarding
the Collateral and Pledgor as the Agent may request.  Pledgor shall mark its
books and records to reflect the security interest of the Agent under this
Agreement.

      Section 3.9.  Additional Securities.  Pledgor shall not consent to or
                    ---------------------                                  
approve the issuance of any additional shares of any class of capital stock of
any issuer of Collateral, or any securities convertible into, or exchangeable
for, any such shares or any warrants, options, rights, or other commitments
entitling any Person to purchase or otherwise acquire any such shares.

                                   ARTICLE IV

                          Rights of Agent and Pledgor
                          ---------------------------

      Section 4.1.  Power of Attorney. Pledgor hereby irrevocably constitutes

substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead and in the name of Pledgor or in its
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

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
the consent of Pledgor, and whether or not an Event of Default has occurred or

      or release any guarantor, indorser, surety, or other party to any of 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

<PAGE>
 
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 for any
purpose not inconsistent with the terms of this Agreement or the Loan 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 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 Loan Agreement, except as provided in Section 3.4 hereof.

      Section 4.4.  Setoff; Property Held by Agent and the Banks.  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 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 or any Bank to Pledgor whether or not the Obligations are then
due. As additional security for the Obligations, Pledgor hereby grants the Agent
and each Bank a security interest in all money, instruments, and other property
of Pledgor now or hereafter held by the Agent or any Bank, including, without
limitation, property held in safekeeping.  In addition to the Agent's or any
Bank's right of setoff and as further security for the Obligations, Pledgor
hereby grants the 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 or any Bank and
all other sums at any time credited by or owing from the Agent or any Bank to
Pledgor.  The rights and remedies of the Agent and each Bank hereunder are in
addition to other rights and remedies (including, without limitation, other
rights of setoff) which the 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 

PLEDGE AGREEMENT - Page 8
<PAGE>
 
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 (5)
      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.

PLEDGE AGREEMENT - Page 9
<PAGE>
 
              (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)  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 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.

of such obligations, indebtedness, and liabilities being hereinafter sometimes
called the "Obligations"):

       (a)     the indebtedness, liabilities and obligations of the Borrower to
     the Banks evidenced by those certain Promissory Notes executed by the
     Borrower pursuant to the Loan Agreement and payable to the order of the
     Banks in the aggregate principal amount of $90,000,000.00;

       (b)     the indebtedness, liabilities and obligations of the Pledgor to

     primary, secondary, joint, several, or joint and several; and

       (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 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.

                                  ARTICLE II

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

      Pledgor represents and warrants to the Agent that:

      Section 2.1.  Title.  Pledgor owns, and with respect to Collateral
                    -----                                               
acquired after the date hereof, Pledgor will own, legally and beneficially, the
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


PLEDGE AGREEMENT - Page 3
<PAGE>
 
Collateral or any part thereof, except for the security interest granted
hereunder.  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.

      Section 2.2.  Financing Statements.  No financing statement covering any
                    --------------------                                      
of the Collateral or its proceeds, except financing statements naming the Agent
as secured party, is on file in any public office.  So long as any amount
remains unpaid on any Obligations or the Agent has any Commitment, Pledgor will
not execute or file, or consent to or permit the filing of, any such financing
statement or statements in any public office, except the financing statement
filed or to be filed with respect to the security interest hereby granted.

      Section 2.3.  Principal Place of Business.  The principal place of
                    ---------------------------                         
business and chief executive office of Pledgor, and the office where Pledgor
keeps its books and records, is located at the address of Pledgor shown at the
beginning of this Agreement.

      Section 2.4.  Percentage of Stock.  The shares of capital stock included
                    -------------------                                       
in the Collateral constitute one hundred percent (100%) of the issued and
outstanding shares of capital stock of A&S.

      Section 2.5.  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 2.6.  Benefit to Pledgor.  The value of the consideration received
                    ------------------                                          
and to be received by the Pledgor as a result of the Borrower, the Agent and the
Banks entering into the Loan Agreement and the Second Amendment 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 and the Borrower's entering into the Loan Agreement and the Second
Amendment have benefitted and may reasonably be expected to benefit the Pledgor
directly and indirectly.

                                  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

                    ------------                                              
to exist, and shall defend the Collateral against, any Lien on the Collateral
except the Permitted Liens, and shall defend Pledgor's rights in the Collateral
and the Agent's security interest in the Collateral against the claims and
demands of all Persons.  Pledgor shall do nothing to impair the rights of the
Agent in the Collateral.

      Section 3.3.  Disposition of Collateral.  Pledgor shall not sell, assign
                    -------------------------                                 
(by operation of law or otherwise), or otherwise dispose of, or grant any option
with respect to the Collateral or any part thereof without the prior written
consent of the Agent.

      Section 3.4.  Distributions.  If Pledgor shall become entitled to receive
                    -------------                                              
or shall receive any stock certificate (including, without limitation, any
certificate representing a stock dividend or a distribution in connection with
any reclassification, increase, or reduction of capital or issued in connection
with any reorganization), option or rights, whether as an addition to, in
substitution of, or in exchange for any Collateral or otherwise, Pledgor agrees
to accept the same as the Agent's agent and to hold the same in trust for the
Agent, and to deliver the same forthwith to the Agent in the exact form
received, with the appropriate endorsement of Pledgor when necessary and/or
appropriate undated stock powers duly executed in blank, to be held by the Agent
as additional Collateral for the Obligations, subject to the terms hereof.  Any
sums paid upon or in respect of the Collateral upon the liquidation, dissolution
or winding up of any issuer of Collateral shall be paid over to the Agent to be
held by it as additional Collateral for the Obligations subject to the terms
hereof; and in case any distribution of capital shall be made on or in respect
of the Collateral or any property shall be distributed upon or with respect to
the Collateral pursuant to any recapitalization or reclassification of the
capital of any issuer of Collateral or pursuant to any reorganization of any
issuer of Collateral, the property so distributed shall be delivered to the
Agent to be held by it, as additional Collateral for the Obligations, subject to
the terms hereof.  All sums of money and property so paid or distributed in
respect of the Collateral that are received by Pledgor shall, until paid or
delivered to the Agent, be held by Pledgor in trust as additional security for
the Obligations.

      Section 3.5.  Further Assurances.  At any time and from time to time, upon
                    ------------------                                          
the request of the Agent, and at the sole expense of Pledgor, Pledgor shall
promptly execute and deliver all such further instruments 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, including, without limitation, the execution and
filing of such financing statements as the Agent may require.  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. Subject to the
right of Pledgor to receive cash dividends and distributions under Section 4.3
hereof, in the event any Collateral is ever received by Pledgor, Pledgor shall
promptly transfer and deliver to the Agent such Collateral so received by
Pledgor (together with any necessary endorsements in blank or undated stock
powers duly executed in blank), which Collateral shall thereafter be held by the
Agent pursuant to the terms of this Agreement.  The Agent shall at all times
have the right to exchange any certificates representing Collateral for
certificates of smaller or larger denominations for any purpose consistent with
this Agreement.

within five (5) days after Pledgor 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

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

      Section 4.1.  Power of Attorney.  Pledgor hereby irrevocably constitutes

     shall direct; (B) after the occurrence and during the continuance of an

     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

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

      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 for any
purpose not inconsistent with the terms of this Agreement or the Loan 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 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 Loan Agreement, except as provided in Section 3.4 hereof.

      Section 4.4.  Setoff; Property Held by Agent and the Banks.  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 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 or any Bank to Pledgor whether or not the Obligations are then
due. As additional security for the Obligations, Pledgor hereby grants the Agent
and each Bank a security interest in all money, instruments, and other property
of Pledgor now or hereafter held by the Agent or any Bank, including, without
limitation, property held in safekeeping.  In addition to the Agent's or any
Bank's right of setoff and as further security for the Obligations, Pledgor
hereby grants the 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 or any Bank and
all other sums at any time credited by or owing from the Agent or any Bank to
Pledgor.  The rights and remedies of the Agent and each Bank hereunder are in
addition to other rights and remedies (including, without limitation, other
rights of setoff) which the 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


PLEDGE AGREEMENT - Page 8
<PAGE>
 
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 (5)
      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 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
      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.

                  Exhibit "F-3" (Guaranty of New Guarantors)
                  ------------------------------------------
<PAGE>
 
                                   GUARANTY
                                   --------


     THIS GUARANTY ("Guaranty"), dated as of July 31, 1996, 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 Loan Agreement (hereinafter defined) or any successor or
permitted assignee thereof, and Texas Commerce Bank National Association, a
national banking association ("TCB"), as agent for itself and each of the other
Banks (TCB in such capacity, together with its successors in such capacity, the
"Agent").

     WHEREAS, National Auto Center, Inc., a Texas corporation (the "Borrower"),
Cellstar Corporation, a Delaware corporation (the "Parent"), the Banks, and the
Agent are parties to that certain Amended and Restated Loan Agreement dated as
of July 20, 1995, as amended by that certain First Amendment to Amended and
Restated Loan Agreement dated as of February 29, 1996 (such Amended and Restated
Loan Agreement, as the same has been and may be amended, supplemented or
modified from time to time, the "Loan Agreement"); and

     WHEREAS, concurrently herewith, the Borrower, the Parent, the Banks and the
Agent are entering into that certain Second Amendment to Amended and Restated
Loan Agreement of even date herewith (the "Second Amendment"), pursuant to
which, among other things, the Borrower's right to obtain Advances under the
revolving credit facility established under the Loan Agreement is being
reinstated as provided in the Second Amendment; and

     WHEREAS, as a condition to the Second Amendment, 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 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 Loan 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 Loan Agreement.
<PAGE>
 
     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 Bank or any other party, or which any Guarantor may have against Borrower,
the Agent, any Bank or any other party, shall be available to, or shall be
asserted by, any Guarantor against the 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 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 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 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 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 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.

                                      -2-
<PAGE>
 
     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 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 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 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 or any Bank is held
to constitute a preference under applicable bankruptcy or insolvency law or if
for any other reason the 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 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.

                                      -3-
<PAGE>
 
     8.   Each Guarantor represents and warrants to the Agent and the Banks
that:

          (a) Each and every representation and warranty contained in the Loan
     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 Parent, the Banks and the Agent
     entering into the Loan 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 Loan Agreement and the extensions of credit thereunder
     have benefited and may reasonably be expected to benefit such Guarantor
     directly or indirectly.

          (c) Such Guarantor has, independently and without reliance upon the
     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 Loan 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 Amended and
     Restated Contribution and Indemnification Agreement of even date herewith,
     among such Guarantor, the Parent, the Partnerships and the other
     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

                                      -4-

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 or any Bank to any
Guarantor whether or not the Guaranteed Indebtedness is then due and
irrespective of whether or not the 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 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 and each Bank, including
without limitation, property held in safekeeping.  In addition to the 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 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 or any Bank and all other sums at any time
credited by or owing from the Agent or any Bank to such Guarantor.  The rights
and remedies of the Agent and each Bank hereunder are in addition to other
rights and remedies (including, without limitation, other rights of setoff)
which the 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.

                                      -5-

          (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 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 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 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 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 and the Banks are relying
upon this Guaranty and the undertakings of each Guarantor hereunder in making
extensions of credit to Borrower under the Loan Agreement and further recognizes
that the execution and delivery of this Guaranty is a material inducement to the
Agent and the Banks in entering into the Second Amendment.  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 and each Bank may exercise any
and all rights granted to them under the Loan Agreement and the other Loan
Documents without affecting the validity or enforceability of this Guaranty.

                                      -7-

     20.  Each Guarantor hereby represents and warrants to the Agent and the
Banks that such Guarantor has adequate means to obtain from the Borrower, the
Parent and the Subsidiaries on a continuing basis information concerning the
financial condition and assets of the Borrower, the Parent and the Subsidiaries
and that such Guarantor is not relying upon the Agent or any Bank to provide
(and neither the 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 EMBODIES THE FINAL, ENTIRE AGREEMENT OF THE GUARANTORS,
THE AGENT AND THE BANKS WITH RESPECT TO THE GUARANTORS' GUARANTY OF THE
GUARANTEED INDEBTEDNESS AND SUPERSEDES ANY AND ALL PRIOR COMMITMENTS,
AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL,
RELATING TO THE SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED OR VARIED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS
OF ANY GUARANTOR, THE AGENT AND THE BANKS.  THERE ARE NO ORAL AGREEMENTS BETWEEN
ANY GUARANTOR, THE AGENT AND THE BANKS.

     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 LOAN AGREEMENT, ANY
OF THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY
OR THE ACTIONS OF THE AGENT OR ANY BANK IN THE NEGOTIATION, ADMINISTRATION, OR

     Re:  Consent to $3,000,000 Term Loan by Banque Nationale de Paris, Houston
          Agency to CellStar Corporation; Consent to Sale of Sam's Operations

Ladies and Gentlemen:

     Reference is hereby made to that certain Amended and Restated Loan
Agreement dated as of July 20, 1995, among National Auto Center, Inc., a Texas
corporation (the "Borrower"), CellStar Corporation, a Delaware corporation (the
"Parent"), each of the banks or other lending institutions which is or may from
time to time become a signatory thereto or any successor or permitted assignee
thereof (each a "Bank" and, collectively, the "Banks"), and Texas Commerce Bank
National Association, a national banking association, as agent for itself and
the other Banks and as issuer of Letters of Credit thereunder (in such capacity,
together with its successors in such capacity, the "Agent"), as amended by that
certain First Amendment to Amended and Restated Loan Agreement dated as of
February 29, 1996, as amended by that certain Second Amendment to Amended and
Restated Loan Agreement of even date herewith (such Amended and Restated Loan
Agreement, as the same has been or may be amended, supplemented or modified from
time to time, being hereinafter referred to as the "Agreement").  The
obligations of Borrower pursuant to the Agreement are guaranteed by the Parent
and the Subsidiaries other than the Foreign Subsidiaries (collectively, the
"Guarantors").  All capitalized terms used and not otherwise defined herein
shall have their respective meanings as set forth in the Agreement.

     The Parent proposes to enter into that certain Loan Agreement dated as of
July 31, 1996 (the "BNP Loan Agreement"), between the Parent and Banque
Nationale de Paris, Houston Agency ("BNP"), pursuant to which BNP will make a
term loan in the principal amount of $3,000,000 (the "BNP Loan") to the Parent
to refinance the outstanding unreimbursed principal balance of a letter of
credit drawing.  The indebtedness of the Parent pursuant to the BNP Loan will be
evidenced by the Parent's Secured Promissory Note dated as of July 31, 1996,
executed by the Parent and payable to the order of BNP in the original principal
amount of $3,000,000 (the "BNP Note").
<PAGE>
 
     The BNP Loan will bear interest at one of the following rates as elected by
the Parent:  (i) the Offshore Rate (as defined in the BNP Loan Agreement), plus
3.50% per annum, or (ii) the BNP Prime Rate (as defined in the BNP Loan
Agreement) plus 2% per annum.  All past due principal and, to the extent
permitted by applicable law, interest on the BNP Note will bear interest at the
Highest Lawful Rate (as defined in the BNP Loan Agreement).

     The BNP Loan will be payable as follows:

          (a)  Accrued and unpaid interest thereon shall be payable monthly;

          (b)  The Parent shall apply any net proceeds the Parent receives on
     account of any refinancing of the Parent's corporate headquarters towards
     payment of the BNP Note, such proceeds to be applied first to accrued and
     unpaid interest and then to reduce the amount of principal remaining to be
     paid under the BNP Note;

          (c)  The Parent shall apply any net proceeds the Parent receives on
     account of the sale or refinancing of any aircraft owned by C&S Air
     Services, Inc. towards payment of the BNP Note, such proceeds to be applied
     first to accrued and unpaid interest and then to reduce the amount of
     principal remaining to be paid under the BNP Note;

          (d)  The Parent shall apply, or cause to be applied, any proceeds
     (other than proceeds of inventory, pagers, pager customer lists and
     accounts receivable) the Borrower, the Parent or CellStar, Ltd. receives on
     account of a sale or other transfer of the Borrower's interest in and to
     the License Agreement (hereinafter defined) and the Borrower's right to
     operate in Sam's Club locations (collectively, the "Sam's Operations"),
     including without limitation any contract or agreement which arises as a
     result of or in connection with the Letter of Intent (hereinafter defined),
     towards payment of the BNP Note, such proceeds to be applied first to
     accrued and unpaid interest and then to reduce the amount of principal
     remaining to be paid under the BNP Note;

          (e)  A final installment of all then unpaid principal and accrued and
     unpaid interest shall be finally due and payable on November 21, 1996.

     As used herein, "License Agreement" means that certain Amended and Restated
National License Agreement dated as of September 1, 1994, between Sam's Club, a
division of Wal-Mart Stores, Inc., a Delaware corporation, and the Borrower.  As
used herein, "Letter of Intent" means that certain letter of intent dated May 6,
1996, among the Borrower, the Parent, CellStar, Ltd. and the Buyer named
therein.

     To secure payment and performance of the BNP Note, the Parent proposes to
execute and deliver or cause to be executed and delivered the documents
described below covering the property and collateral described below
(collectively, the "BNP Collateral"):

                                      -2-
<PAGE>
 
          (a)  The Borrower shall grant to BNP a first and prior perfected
     security interest in 65% of the capital stock of CellStar International
     Corporation/S.A., pursuant to that certain Stock Pledge Agreement dated
     July 31, 1996, executed by the Borrower in favor of BNP (the "BNP Stock
     Pledge Agreement").

          (b)  The Parent shall cause to be collaterally assigned to BNP all of
     the Parent's, the Borrower's and CellStar, Ltd.'s right, title and interest
     in and to any contract or agreement which exists or may exist with respect
     to the sale or other transfer of the Borrower's interest in and to the
     License Agreement and the Borrower's rights to operate in Sam's Club
     locations as set forth in the License Agreement, including without
     limitation any contract or agreement which arises as a result of or in
     connection with the Letter of Intent, together with all proceeds, other
     than proceeds of inventory, pagers, pager customer lists and accounts
     receivable, from any sale or transfer pursuant to such contract or
     agreement.  The collateral assignment of such contract shall be contained
     in that certain Security Agreement dated July 31, 1996, executed by the
     Borrower, the Parent and CellStar, Ltd. in favor of BNP (the "BNP
     Collateral Assignment").

          (c)  The Parent, the Borrower and CellStar, Ltd. shall execute Uniform
     Commercial Code financing statements for filing in the appropriate
     jurisdictions to perfect BNP's security interest in the BNP Collateral
     (collectively, the "BNP Financing Statements").

     At your request, the Agent and the Banks hereby consent to the BNP Loan,
the BNP Loan Agreement, the BNP Note, the BNP Stock Pledge Agreement, the BNP
Collateral Assignment, the BNP Financing Statements, all terms and provisions
thereof and all liens and security interests granted thereby to BNP in the BNP
Collateral to secure the BNP Note, to the extent the foregoing would otherwise
violate any of the terms and provisions of Section 10.1 or Section 10.2 of the
Agreement, provided that such documents are in the form approved by the Agent
and contain terms and provisions as described herein.  Without in any way
limiting the foregoing, the Agent and the Banks specifically consent to the
payment terms of the BNP Note as described herein.

     Further, the Agent and the Banks hereby agree that any and all liens and
security interests of the Agent, for the pro rata benefit of the Banks, in the
BNP Collateral are subordinated to the liens and security interests of BNP in
the BNP Collateral, to the extent the BNP Collateral secures payment of the
indebtedness evidenced by the BNP Note.

     Further, the Agent, BNP and the other Banks hereby consent to any sale of
the Sam's Operations and the release by the Agent and BNP of their respective
security interests in the assets sold in connection therewith, so long as (a)
such sale is upon terms substantially similar to those outlined in the Letter of
Intent, including a cash purchase price not less than the range specified in the
Letter of Intent, and (b) the net cash proceeds from such sale shall be applied
as follows:

                                      -3-
<PAGE>
 
          (i)  Net cash proceeds attributable to the BNP Collateral shall be
     paid to BNP for application first to accrued and unpaid interest on the BNP
     Note and then to the outstanding principal balance thereof; and

          (ii) Net cash proceeds attributable to the BNP Collateral remaining
     after payment in full of the BNP Note, together with all other net cash
     proceeds, shall be paid to the Banks, pro rata, for application to the
     Obligations in accordance with the Loan Agreement.  The principal reduced
     by such proceeds may be reborrowed by the Borrower, subject to the
     Borrowing Base as recalculated as of the closing date of such sale in
     accordance with the provisions of the Loan Agreement.

Nothing herein shall be construed as a consent to the sale of the Sam's
Operations pursuant to any terms other than those specified herein.

     The consents granted herein are limited to the covenants and sections of
the Agreement specifically stated herein and the specific transactions and
documents specified herein.  The consents granted herein shall not be construed
as a consent to or waiver of any other Default which may now exist or hereafter
occur or any other violation of any term, covenant or provision of the Agreement
or any other Loan Document.  All rights and remedies of the Banks and Agent are
hereby expressly reserved with respect to any such Default.  The consents
granted herein do not affect or diminish the right of Agent and the Banks to
require strict performance by the Borrower and each Guarantor of each provision
of any Loan Document to which it is a party, except as expressly provided
herein.  All terms and provisions of, and all rights and remedies of Agent and
the Banks under, the Loan Documents shall continue in full force and effect and
are hereby confirmed and ratified in all respects.

     THIS LETTER EMBODIES THE FINAL, ENTIRE AGREEMENT AMONG THE PARTIES HERETO
RELATING TO THE CONSENTS AND AGREEMENTS SET FORTH HEREIN AND SUPERSEDES ANY AND
ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS AND UNDERSTANDINGS, WHETHER
WRITTEN OR ORAL, RELATING TO THE CONSENTS AND AGREEMENTS SET FORTH HEREIN AND
MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OF THE PARTIES HERETO.  THERE ARE NO
ORAL AGREEMENTS AMONG THE PARTIES HERETO.

     THIS LETTER 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 letter may be executed in any number of counterparts and by different
parties on separate counterparts, each of which shall be an original and all of
which taken together shall constitute one and the same agreement.  This letter
shall not be effective unless and until the Agent, the Banks, the Borrower, and
the Guarantors each have executed and delivered a counterpart hereof, whereupon
this letter shall be effective as of the date first above written.

                                      -4-

     All capitalized terms used and not otherwise defined herein shall have
their respective meanings as set forth in the Loan Agreement, as defined in the
Second Amendment to Amended and Restated Loan Agreement to which this is an
Annex (the "Amendment").

     1.  Each of the Borrower and the Guarantors (other than the Partnerships)
is a corporation duly organized, validly existing, and in good standing under
the laws of the state of its incorporation.  Each of the Partnerships is a
limited partnership duly organized and validly existing under the laws of the
State of Texas.

     2.  Each of the Borrower and the Guarantors (other than the Partnerships)
has the corporate power and authority to execute, deliver, and perform the
Amendment and the other Loan Documents to which such Person is a party. The
execution, delivery, and performance by each such Person of the Amendment and
the other Loan Documents to which such Person is a party and compliance with the
terms and provisions thereof have been duly authorized by all requisite
corporate action on the part of such Person and do not and will not (a) violate
or conflict with, or result in a breach of, or require any consent under (i) the
articles or certificate of incorporation or bylaws of such Person, (ii) any
applicable law, rule, or regulation or any order, writ, injunction, or decree of
any Governmental Authority or arbitrator, or (iii) any agreement or instrument
to which such Person is a party or by which such Person or any of its property
is bound or subject, or (b) constitute a default under any such agreement or
instrument, or result in the creation or imposition of any Lien (except Liens
created in favor of the Agent pursuant to the Loan Documents) upon any of the
revenues or assets of such Person.

     3.  Each of the Partnerships, and each Person executing any Loan Documents
on behalf of any Partnership, has the power and authority to execute, deliver,
and perform the Amendment and the other Loan Documents to which such Partnership
is a party.  The execution, delivery, and performance by each Partnership, and
by each Person on behalf of any Partnership, of the Amendment and the other Loan
Documents to which such Partnership is a party and compliance with the terms and
provisions thereof have been duly authorized by all requisite action on the part
of such Person and do not and will not (a) violate or conflict with, or result
in a breach of, or require any consent under (i) the partnership agreement of

writ, injunction, or decree of any Governmental Authority or arbitrator, or
(iii) any agreement or instrument to which such Partnership is a party or by
which it or any of its property is bound or subject, or (b) constitute a default

     4.  The Amendment and the other Loan Documents to which the Borrower or any
Guarantor is a party have been duly executed and delivered by such Person.  The
Amendment and the other Loan Documents to which the Borrower or any Guarantor is
a party constitute the legal, valid, and binding obligations of such Person
enforceable against such Person in accordance with their respective terms,
except as the enforceability thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium, or other similar laws affecting the enforcement of
creditors' rights generally.

     5.  There are no legal or arbitral proceedings, and no proceedings by or
before any Governmental Authority, pending or, to our knowledge, threatened
against or affecting the Borrower, any Guarantor, any other Subsidiary or any
Foreign Affiliate, or any properties or rights of any such Person, which if
adversely determined, would have a material adverse effect on the business,
condition (financial or otherwise), operations, prospects, or properties of any
such Person.

     6.  No authorization, consent, or approval of, or filing or registration
with, any Governmental Authority is required for the execution, delivery, and
performance by the Borrower or any Guarantor  of the Loan Documents to which
such Person is a party.

     7.  All of the shares of capital stock of each Subsidiary (other than the
Foreign Subsidiaries) have been duly authorized and validly issued and are fully
paid and nonassessable.  None of the shares of capital stock of any Subsidiary
(other than the Foreign Subsidiaries) are subject to any restriction on transfer
or assignment, except compliance with applicable securities laws and
regulations.

                             TERMS AND CONDITIONS


1. Contract prices are based on a firm commitment by Buyer to take delivery of
   the agreed quantity of Products during the Initial Term. Products may be
   aggregated to reach the contract volume commitment. If Buyer takes delivery
   of less than the committed quantity during the Initial Term, a volume
   shortfall adjustment will be calculated and billed to Buyer based on unit
   shipment shortfall from the committed quantity during the Initial Term. The
   charge per unit short will be [REDACTED] for up to [REDACTED] units short, 
   [REDACTED] for more than [REDACTED] units and up to [REDACTED] units short,
   and [REDACTED] for more than [REDACTED] units short of the committed
   quantity. [REDACTED] 

2. Motorola will issue rebates promptly after the month in which the Products
   were delivered and after Product payment is received, in the form of a credit
   memo that may be applied to the purchase of additional Products.

3. Motorola may sell other cellular subscriber equipment to Buyer if requested.
   Any such sale during the term of this Agreement will be at Motorola's price,
   and in accordance with the terms and conditions herein unless otherwise
   specified by Motorola.
 
4. Buyer will exercise its best efforts to submit purchase orders no less than
   thirty (30) days prior to the requested shipment dates and acknowledges that
   shipment on the requested date is more likely as the lead time is increased.
   If Motorola accepts a purchase order requesting shipment within thirty (30)
   from the date Motorola receives the order, Buyer agrees that the ordered
   Products will be shipped when it is practicable for Motorola to do so.
 
5. Payment terms are net 30 days.
 
6. Two percent (2%) of the invoice price of applicable Products purchased under
   this Agreement will be accrued as a cooperative promotional allowance.
   Application for funds must be made according to the Motorola Cellular Co-op
   Advertising and Promotion Plan, US Version January 1994 or any subsequent
   revision thereof that may be implemented by Motorola, which is incorporated
   herein by reference. 

7. All orders and shipments shall be in multiples of 5 units per model.
 
8. (a) Buyer shall be a non-exclusive distributor of the Products in those
   geographical areas identified in Attachment E, and in any other market
   attachment that may later be agreed upon by the parties as an amendment to
   this Agreement (Buyer's "Territory").

                             TERMS AND CONDITIONS 
  
    (b) This Agreement may be amended by adding markets to Buyer's Territory.
    Any such additional markets will be added by mutual agreement and will be
    identified in separate attachments. It is the intention of the parties that
    any market additions to this Agreement will have purchase volume
    commitments, market development funds, and other similar incentives and
    obligations, separate from and in addition to those incentives and
    requirements associated with the markets identified in Attachment E.

    (c) Any markets may be withdrawn from Buyer's Territory by Motorola on
    ninety (90) days advance notice to Buyer. Buyer agrees that Motorola may
    withdraw markets from Buyer's Territory at Motorola's discretion, with or
    without cause, without any liability or obligation to Buyer or its
    customers; provided, however, that Motorola will reimburse Buyer for a
    reasonable cancellation fee paid to terminate a lease commitment(s)
    reasonably occasioned by Buyer's obligation to sell Products in that market
    by this Agreement.

    (d) From time to time Motorola may request Buyer to service a certain market
    not on the current Attachment E for a limited period of time. The terms of
    any such arrangement shall be in writing and mutually agreeable to the
    parties.

    (e) Buyer's distribution of the Products is limited to Buyer's Territory.
    Buyer shall not transship, sell, or otherwise transfer Products outside its
    Territory, and Buyer shall incorporate this limitation into all of its agent
    and distributor equipment agreements as a condition of resale of the
    Products and reasonably enforce same. Sales within the Territory without
    transshipment is a material condition to Buyer's rights under this
    Agreement, and it is agreed that any direct or indirect distribution,
    transshipment and/or sale of Products outside the Territory by Buyer or
    others purchasing through Buyer shall be a material breach of this Agreement
    and will result in substantial damage to Motorola which will be difficult to
    quantify. Accordingly, in the event of such the parties agree that Motorola,
    in addition to any other remedies it may have under applicable law and this
    Agreement, may reject some or all purchase orders from Buyer for any model
    or models of Product, including Premier products, until Buyer can
    demonstrate that Buyer has instituted policies and procedures to prevent any
    such occurrences in the future.

9.  All units will carry mutually agreed upon designated logos. Buyer will
    provide photographic quality artwork 30 days prior to requested ship date.
    Buyer represents and warrants that it has the right by way of ownership or
    otherwise, to use such logo and further agrees to indemnify and hold
    Motorola harmless for any losses, damages or other liabilities resulting
    from the use of the designated logo.

10. Buyer shall provide Motorola on a quarterly basis, not less than thirty (30)
    days prior to the start of the next quarter, a continuous usage forecast for
    the next two (2) calendar quarters (the "Quarterly Forecast") to assist
    Motorola in maintaining an orderly production flow for the purpose of
    Buyer's delivery requirements. Buyer shall indicate the Product model number
    and projected purchase volume by units for each month of the quarter.

                             TERMS AND CONDITIONS
 
11. Buyer shall provide Motorola on a quarterly basis, not less than thirty (30)
    days prior to the start of the next quarter, a firm processable purchase
    order for the first month of the Quarterly Forecast; provided, however, that
    a delivery(ies) scheduled in such first month may be rescheduled by Buyer
    into the second month on notice to Motorola not less than [REDACTED] prior
    to the scheduled delivery date.
 
12. (a) During the Initial Term of this Agreement, if Motorola reduces the price
    of a particular model of Product, then Buyer shall be entitled to the
    benefit of price protection for [REDACTED}

    (b) Motorola will make a price adjustment for each Eligible Unit equal to
    the difference between Buyer's net purchase price (invoice price less rebate
    and any promotional amounts) and the new net price (invoice price less
    rebate and any promotional amounts). Price protection will be paid as a
    credit against future purchases within fifteen (15) days after the end of
    the month of receipt of price protection claim and required documentation.

13. As a condition to the price protection described herein, Buyer shall furnish
    Motorola with accurate monthly reports of Buyer inventory (by major product
    category) of Products. Each such inventory report shall be received by your
    Motorola Account Executive no later than the first Thursday following the
    close of Motorola's shipment month (dates listed below), and shall include
    all inventories maintained by Buyer and its affiliates, including
    inventories maintained by major agents or at drop ship distribution points.
    It is specifically understood that inventories maintained at Sam's Club
    kiosk locations shall be estimates only. If any such report is received
    after the applicable date listed below, the time period for shipments
    protected against price reductions shall be reduced by one day for each day
    such report is late.

    Monthly reports of inventory are to be received by Motorola by: 
 
    Thursday       8/01/96
    Thursday       8/29/96
    Thursday       10/03/96

    Wednesday      11/27/96*
    Thursday       1/02/97
 
    * November inventory date is on Wednesday due to the Thanksgiving national
      holiday.

15. Motorola will offer its Signature Products (including the StarTAC(TM) 
    cellular phone) to Buyer for distribution to Buyer's dealers and agents at
    locations pre-approved by Motorola under the terms of Motorola's Signature
    program in effect from time to time. Motorola will drop ship Buyer's orders
    for Signature Products direct to each approved dealer and/or agent location,
    with the related invoice being sent to the Buyer. Signature Products
    delivered to a location may not be transshipped to any other location nor
    offered for sale from any other location without Motorola's express prior
    written consent.

                       SUPPLEMENTAL TERMS AND CONDITIONS


1. PRICES The prices for the Products purchased hereunder shall be as set forth
   in Attachment A to the Agreement.

2. ORDERS AND FORECASTS (a) Orders. All orders by Buyer shall be only upon the
   terms and conditions of this Agreement. The only effect of any terms and
   conditions in Buyer's orders or elsewhere shall be to request the time and
   place of delivery and number of units to be delivered, subject to Seller's
   acceptance, but they shall not change, alter or add to the terms and
   conditions of this Agreement in any other way. Seller's invoice shall also
   not change the terms and conditions of this Agreement. (b) Forecasts. During
   the term of this Agreement, Buyer shall use its best efforts to update, on a
   quarterly basis, a continuous usage forecast to assist Seller in maintaining
   an orderly production flow for the purpose of meeting Buyer's delivery
   requirements. Buyer's failure to provide such information may be considered
   cause by Seller for excusable delivery delay.

3. CANCELLATION Buyer may cancel orders placed in accordance with the terms and
   conditions of this Agreement upon payment of cancellation charges which shall
   include all costs incurred or committed for unless such costs are otherwise
   recoverable through the sale of the product on a timely basis. Payment shall
   be due within thirty (30) days of the date of invoice. Seller agrees to
   divert completed material and work in process from canceled orders to other
   requirements wherever possible in order to minimize cancellation charges.

4. DELIVERY AND PAYMENT (a.) All deliveries are FOB Motorola's plant. Each such
   delivery will be separately invoiced and payment from Buyer shall be due
   thirty (30) days from the date thereof without regard to other deliveries.
   DELIVERY DATES ARE BEST ESTIMATES ONLY. (b.) Title to the Products sold shall
   pass to Buyer at the FOB point.

5. FORCE MAJEURE Neither party shall be liable for any delay or failure to
   perform due to any cause beyond its reasonable control except the obligation
   to pay money when due. Causes include but are not limited to strikes, acts of
   God, acts of the other party, interruptions of transportation or inability to
   obtain necessary labor, materials or facilities, or default of any supplier,
   or delays in FCC frequency authorization or license grant. The delivery
   schedule shall be considered extended by a period of time equal to the time
   lost because of any excusable delay. To the extent that MOTOROLA is unable to
   manufacture and deliver the annual commitment, it shall be reduced on a pro-
   rata basis. In the event MOTOROLA is unable to wholly or partially perform
   for a period greater than forty-five (45) days because of any cause beyond
   its reasonable control, either party may terminate any delayed order without
   any liability.

6. WARRANTY MOTOROLA warrants the Products to the original subscriber buyers or
   lessees only in accordance with its Limited Warranty attached to the
   Agreement, or as the Limited Warranty may be revised by Motorola from time to
   time (to be applicable to units shipped by Motorola on or after the effective
   date of the revision), and makes no representation or warranty of any other
   kind, express or implied. EXCEPT AS OTHERWISE PROVIDED IN THE LIMITED
   WARRANTY, MOTOROLA SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTY OF
   MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

7. PATENT AND COPYRIGHT INDEMNIFICATION (a) MOTOROLA agrees to defend, at its
   expense, any suits against Buyer and third parties purchasing Motorola
   products from Buyer based upon a claim that any products furnished hereunder
   directly infringes a U.S. patent or copyright and to pay costs and damages
   finally awarded in any such suit, provided that MOTOROLA is notified promptly
   in writing of the suit and at Motorola's request and at its expense is given
   control of said suit and all requested assistance for defense of same. If the
   use or sale of any product(s) furnished hereunder is enjoined as a result of
   such suit, MOTOROLA at its option and at no expense to Buyer, shall obtain
   for Buyer the right to use or sell said product(s) or shall substitute an
   equivalent product reasonably acceptable to Buyer and extend this indemnity
   thereto or shall accept the return of the product(s) and reimburse Buyer the
   purchase price therefor, less a reasonable charge for reasonable wear and
   tear. This indemnity does not extend to any suit based upon any infringement
   or alleged infringement of any patent or copyright by the alteration of any
   products furnished by MOTOROLA or by the combination of any products(s)
   furnished by MOTOROLA and other elements nor does it extend to any
   products(s) of Buyer's design or formula. The foregoing states the entire
   liability of MOTOROLA for patent or copyright infringement. (b) IN NO EVENT
   SHALL MOTOROLA BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING FROM
   INFRINGEMENT OR ALLEGED INFRINGEMENT OF PATENTS, COPYRIGHTS, OR OTHER
   INTELLECTUAL PROPERTY RIGHTS.

                       SUPPLEMENTAL TERMS AND CONDITIONS

 8. LICENSE DISCLAIMER Nothing contained herein shall be deemed to grant either
    directly or by implication, estoppel, or otherwise, any license under any
    patents, copyrights, trademarks or trade secrets of MOTOROLA.

 9. TAXES Except for the amount, if any, of state and local tax stated in the
    Agreement, the prices set forth herein are exclusive of any amount for
    Federal, State and/or Local excise, sales, use, property, retailer's,
    occupation or any other assessment in the nature of taxes however
    designated, on the products and/or services provided under this Agreement.
    If any such excluded tax, exclusive however, of any taxes measured by
    Seller's net income or taxes based on Seller's gross receipts or based on
    Seller's franchise, is determined to be applicable to this transaction or to
    the extent MOTOROLA is required to pay or bear the burden thereof, one
    hundred percent (100%) thereof shall be added to the prices set forth herein
    and paid by Buyer. Personal property taxes assessable on the products shall
    be the responsibility of Buyer. In the event Buyer claims exemption from
    sales, use or other such taxes under this Agreement, Buyer shall hold
    Motorola harmless of any subsequent assessments levied by a proper taxing
    authority for such taxes, including interest, penalties, and late charges.

10. TECHNICAL ASSISTANCE Motorola's warranty shall not be enlarged, and no
    obligation or liability shall arise out of Motorola's rendering of technical
    advice, facilities or service in connection with Buyer's purchase of the
    products furnished.

11. LIMITATION OF LIABILITY EXCEPT FOR PERSONAL INJURY, AND EXCEPT FOR PARAGRAPH
    7 PATENT AND COPYRIGHT INDEMNIFICATION, MOTOROLA'S TOTAL LIABILITY, WHETHER
    FOR BREACH OF CONTRACT, WARRANTY, NEGLIGENCE, STRICT LIABILITY IN TORT OR
    OTHERWISE, IS LIMITED TO THE PRICE OF THE PARTICULAR PRODUCTS SOLD HEREUNDER
    WITH RESPECT TO WHICH LOSSES OR DAMAGES ARE CLAIMED. BUYER'S SOLE REMEDY IS
    TO REQUEST MOTOROLA AT MOTOROLA'S OPTION TO EITHER REFUND THE PURCHASE
    PRICE, REPAIR OR REPLACE PRODUCT(S) THAT ARE NOT AS WARRANTED. IN NO EVENT
    WILL MOTOROLA BE LIABLE FOR ANY LOSS OF USE, LOSS OF TIME, INCONVENIENCE,
    COMMERCIAL LOSS, LOST PROFITS OR SAVINGS OR OTHER INCIDENTAL OR
    CONSEQUENTIAL DAMAGES TO THE FULL EXTENT SUCH MAY BE DISCLAIMED BY LAW.

12. LOGOS AND TRADEMARKS In order that Seller may protect its trademarks, trade
    names, corporate slogans, corporate logo, goodwill and product designations,
    Buyer, without the express written consent of Seller, shall have no right to
    use any such marks, names, slogans or designations of Seller in the sales,
    lease or advertising of any products or on any product container, component
    part, business forms, sales, advertising and promotional materials or other
    business supplies or material, whether in writing, orally or otherwise.

13. PARTY RELATIONSHIP This Agreement does not create any agency, joint venture
    or partnership between Buyer and Seller. Buyer shall not impose or create
    any obligation or responsibility, express or implied, or make any promises,
    representations or warranties on behalf of Seller, other than as expressly
    provided herein.

14. WAIVER The failure of either party to insist in any one or more instances,
    upon the performance of any of the terms or conditions herein or to exercise
    any right hereunder shall not be construed as a waiver or relinquishment of
    the future performance of any such terms or conditions or the future
    exercise of such right but the obligation of the other party with respect to
    such future performance shall continue in full force and effect.

15. DEFAULT In the event that either party shall be in breach or default of any
    of the terms or conditions of this Agreement and such breach or default
    shall continue for a period of thirty (30) days after the giving of written
    notice to the breaching party, then subject to the other terms and
    conditions of this Agreement, the other party, in addition to other rights
    and remedies it may have in law or equity, shall have the right to
    immediately cancel this Agreement without any charge or liability
    whatsoever.

16. GOVERNMENT SALES In the event that Buyer elects to sell Motorola products or
    services to the U.S. Government or a prime contractor selling to the U.S.
    Government, Buyer remains solely and exclusively responsible for compliance
    with all statutes and regulations governing sales to the U.S. Government.
    Motorola makes no representations, certifications or warranties whatsoever
    with respect to the ability of its goods, services or prices to satisfy any
    such statutes or regulations. Failure of Buyer to conduct any sales to the
    U.S. Government or to U.S. Government prime contractors in strict accordance

                MOTOROLA LIMITED WARRANTY FOR THE UNITED STATES
                  CELLULAR SUBSCRIBER RADIOTELEPHONE PRODUCTS

I.  WHAT THIS WARRANTY COVERS AND FOR HOW LONG:

MOTOROLA INC. (MOTOROLA) warrants the MOTOROLA Cellular Subscriber
Radiotelephone products and accessories against defects in material and
workmanship under normal use and service for a period of time specified by the
product's serial number from the date of installation. (NOTE: Installation, in
the case of radiotelephones, accessories or batteries that are not installed in
a vehicle, means the date that the product is placed into subscriber service.
Installation will be deemed to be no later than thirty (30 days from date of
delivery of the Product to you the owner.) The warranty time period is specified
by the last digit of the mechanical serial number found on each cellular
product. Products sold under this warranty may have either a "P", "Y", "A", "B",
"C", or "D" or nothing in the eleventh position of the serial number. If there
is no letter or an "A", the product comes with a (1) one year warranty. Products
that have a "D" have a (2) two year warranty. Products that have a "Y" or a "B"
have a (3) three year warranty, and products that have a "P" or a "C" have a (5)
five year warranty commencing from the date of installation. The warranty time
period for radiotelephone accessories and batteries is as follows:

     Transportable and Carry Phone batteries:              1 year
     Portable or Digital Personal Communicator(TM) (DPC)
      telephone batteries:                                 1 year
     Carrying cases (excluding leather briefcases):        Defect free at time
                                                            of shipment
     Other radiotelephone accessories:                     1 year

MOTOROLA, at its option, will at no charge either repair, replace, or refund the
purchase price of the Cellular Subscriber Radiotelephone Product during the 
warranty period, provided it is returned in accordance with the terms of this 
warranty to the MOTOROLA Cellular Service Center or distributor's service shop 
qualified by MOTOROLA. Repair, at MOTOROLA's option, may include the replacement
of parts or boards with functionally equivalent reconditioned or new parts or 
boards. Replaced parts, accessories, batteries, or boards are warranted for the 
balance of the original time period. All replaced accessories, batteries, parts 
and cellular telephone equipment shall become the property of MOTOROLA.

II. WARRANTY CONDITIONS:

This express limited warranty is extended by MOTOROLA to the original subscriber
buyer or lessee only and is not assignable or transferable to subsequent 
subscriber buyers or lessees. This is the complete warranty for Cellular 
Subscriber Radiotelephone Products by MOTOROLA. MOTOROLA assumes no obligation 
or liability for additions or modifications to this warranty unless made in 
writing and signed by an officer of MOTOROLA. Unless made in separate written 
agreement between MOTOROLA and you, MOTOROLA does not warrant the installation, 
maintenance or service of the equipment, accessories, batteries or parts. 
Portable or DPC (Nickel Cadmium) batteries are warranted only if battery 
capacity falls below 80% of rated capacity, or the battery develops leakage. 
This warranty becomes void for all types of batteries if:

     a. the batteries are charged by other than MOTOROLA approved battery 
        chargers specified for the charging of the battery.
     b. any of the seals on the battery are broken or show evidence of 
        tampering.
     c. the battery is used in equipment or service other than the cellular
        telephone equipment for which it is specified.

MOTOROLA cannot be responsible in any way for any ancillary equipment not 
furnished by MOTOROLA which is attached to or used in connection with MOTOROLA's
Cellular Subscriber Radiotelephone Products, or for operation of our equipment 
with any ancillary equipment and all such equipment is expressly excluded from 
this warranty. Furthermore, MOTOROLA cannot be responsible for any damage to 
MOTOROLA equipment resulting from the use of ancillary equipment not furnished 
by MOTOROLA for use with cellular subscriber equipment.

When the product is used in conjunction with ancillary or peripheral equipment 
not manufactured by MOTOROLA, MOTOROLA does not warrant the operation of the 
product/peripheral combination, and MOTOROLA will honor no warranty claim where 
the product is used in such a combination and it is determined by MOTOROLA that 
there is no fault with the MOTOROLA product. MOTOROLA specifically disclaims any
responsibility for any damage caused in any way by the use of portable 
radiotelephone accessories and peripherals (specific examples include, but are 
not limited to: batteries, chargers, adapters, and power supplies) when such 
accessories and peripherals are not manufactured or supplied by MOTOROLA. 
MOTOROLA disclaims liability for range, coverage, availability, or operation of 
the Cellular System which is provided by the Carrier.

III. WHAT THIS WARRANTY DOES NOT COVER:

(a) Defects or damage resulting from use of the product in other than its normal
and customary manner. (b) Defects or damage from misuse, accident or neglect. 
(c) Defects or damage from improper testing, operation, maintenance, 
installation, adjustment, or any alteration or modification of any kind. (d) 
Breakage or damage to antennas unless caused directly by defects in material or 
workmanship. (e) Products disassembled or repaired in such a manner as to 
adversely affect performance or prevent adequate inspection and testing to 
verify any warranty claim. (f) Products which have had the serial number removed
or made illegible. (g) Defects or damage due to spills of food or liquid. (h) 
Control Unit Coil Cords that are stretched or have the modular tab broken. (i) 
All plastic surfaces and all other externally exposed parts that are scratched 
or damaged due to customer normal use. (j) Leather briefcases (which are covered
under separate manufacturers' warranties). (k) Products rented on a 
month-to-month basis. (l) The control unit keypad assembly, control unit 
displays, and control unit coil cords are not covered after the first year from 
installation.

IV. HOW TO GET WARRANTY SERVICE:

To receive warranty service, present your equipment to the facility described 
below, along with your bill of sale or comparable substitute proof of sale or 
lease bearing the date of installation, transceiver serial number, electronic 
serial number, and installation facility if applicable.

Warranty service is available by returning MOTOROLA branded Radiotelephone 
Products to a MOTOROLA Cellular Service Center authorized in writing by a 
MOTOROLA Area Service Manager to perform warranty work on MOTOROLA Cellular 
Subscriber Radiotelephone products. A Carrier or Distributor branded 
Radiotelephone Product may be returned to either (a) the specific cellular 
service shop qualified by MOTOROLA's Cellular Subscriber Services Department in 
writing and operated by or affiliated with the cellular distributor which the 
Distributor designates or (b) a MOTOROLA Authorized Cellular Service Center. In
most cases the service shop which installed your Cellular Radiotelephone and 
accessories will provide warranty service. If you need additional information, 
contact the shop that installed your Radiotelephone, the customer service 
department of your cellular system operator, or MOTOROLA at the address at the 
bottom of this page.

In the case of vehicular installation, the vehicle in which the Radiotelephone 
Product is installed should be driven to the service shop, as analysis of any 
problem may require inspection of the entire vehicular installation. In the case
of non-vehicular installation, the unit or accessories, together with any 
detachable parts such as antennas, battery packs, and chargers, must be 
delivered to a qualified MOTOROLA Cellular Service Center, or a MOTOROLA-
qualified service shop, transportation and insurance prepaid. When sent or
brought to the servicer, the Radiotelephone Product must be accompanied by your
name, address, and telephone number, name of cellular Carrier, and a description
of the problem.

V.  GENERAL PROVISIONS:

This warranty sets forth our responsibilities regarding this product. Repair,
replacement or refund of the purchase price at MOTOROLA's option, is your
exclusive remedy. THIS WARRANTY IS GIVEN IN LIEU OF ALL OTHER EXPRESS
WARRANTIES. IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES
OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED TO THE
DURATION OF THIS LIMITED WARRANTY. FURTHER, AS THE CELLULAR CARRIER IS NOT
CONTROLLED BY MOTOROLA, NO WARRANTY IS MADE AS TO COVERAGE, AVAILABILITY OR
GRADE OF SERVICE PROVIDED BY THE CELLULAR CARRIER. IN NO EVENT SHALL MOTOROLA BE
LIABLE FOR DAMAGES IN EXCESS OF THE PURCHASE PRICE OF THE CELLULAR
RADIOTELEPHONE PRODUCT, FOR ANY LOSS OF USE, LOSS OF TIME, INCONVENIENCE,
COMMERCIAL LOSS, LOST PROFITS OR SAVINGS OR OTHER INCIDENTAL, SPECIAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE SUCH PRODUCT,
TO THE FULL EXTENT SUCH MAY BE DISCLAIMED BY LAW.

VI.  PATENT AND SOFTWARE PROVISIONS:

MOTOROLA  will defend at its own expense, any suit brought against you to the 
extent that it is based on a claim that the Cellular Subscriber Radiotelephone 
Product parts infringes a United States patent, and MOTOROLA will pay those 
costs and damages finally awarded against you in any such suit which are 
attributable to any such claim, but such defense and payments are conditioned on
the following: (i) that MOTOROLA will be notified promptly in writing by you of 
any notice of such claim; and (ii) that MOTOROLA will have sole control of the 
defense of such suit and all negotiations for its settlement or compromise; and 
(iii) should the Cellular Radiotelephone, accessory, battery or parts become, or
in MOTOROLA's opinion be likely to become the subject of a claim of infringement
of a United States patent that you will permit MOTOROLA, at its option and 
expense, either to procure for you the right to continue using the Cellular 
Radiotelephone or parts or to replace or modify the same so that it becomes 
non-infringing or to grant you a credit for such Cellular Radiotelephone or 
parts as depreciated and accept its return.  The depreciation will be an equal 
amount per year over the lifetime of the Cellular Subscriber Radiotelephone, 
accessories, battery or parts as established by MOTOROLA.

MOTOROLA will have no liability to you with respect to any claim of patent 
infringement which is based upon the combination of the Cellular Radiotelephone 
or parts furnished hereunder with software, apparatus or devices not furnished 
by MOTOROLA, nor will MOTOROLA have any liability for the use of ancillary 
equipment or software not furnished by MOTOROLA which is attached to or used in 
connection with the Cellular Radiotelephone.  The foregoing states the entire 
liability of MOTOROLA with respect to infringement of patents by the Cellular 
Radiotelephone, accessories, batteries or any parts thereof.

Laws in the United States and other countries preserve for MOTOROLA certain 
exclusive rights for copyrighted MOTOROLA software such as the exclusive rights 
to reproduce in copies and distribute copies of such MOTOROLA software.  
MOTOROLA software may be copied into, used in and redistributed with only the 
Cellular Subscriber Radiotelephone Product associated with such MOTOROLA 
software.  No other use, including without limitation disassembly, of such 
MOTOROLA software or exercise of exclusive rights in such MOTOROLA software is 
permitted.

VII. STATE LAW RIGHTS:

SOME STATES DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR 
CONSEQUENTIAL DAMAGES, OR LIMITATIONS ON HOW LONG AN IMPLIED WARRANTY LASTS.  SO
THE ABOVE LIMITATIONS OR EXCLUSIONS MAY NOT APPLY TO YOU.

This warranty gives you specific legal rights, and you may also have other 
rights which vary from state to state.

                               LIMITED WARRANTY

MOTOROLA, INC. (Motorola) warrants this Motorola cellular accessory against 
defects in material and workmanship under normal use for ONE YEAR from the date 
of original retail purchase.  This warranty extends to the original retail 
purchaser only and is not transferable.  Motorola, at its option, will at no 
charge either repair the accessory (with new or reconditioned parts) or replace 
the accessory or refund the purchase price of the accessory during the warranty 
period.  Repaired/replacement accessories are warranted for either ninety days 
or the remainder of the original warranty period, whichever is longer.  All 
replaced items become Motorola's property.  This warranty does not cover defects
or damage resulting from abnormal use, misuse, mishandling, neglect, accident or
tampering.

You can obtain warranty service through your original place of purchase in most 
cases.  Or you can obtain warranty service by returning the accessory directly 
to Motorola.  In either case, you must return the accessory with transportation 
prepaid and provide proof that the accessory is within the warranty period (for 
example, a dated purchase receipt).  For more information, including about 
returning an accessory to Motorola, please call the Motorola Cellular 
Information Center toll-free at 1-800-331-6456 in the USA.

THIS IS THE COMPLETE WARRANTY FOR THE ACCESSORY BY MOTOROLA AND SETS FORTH YOUR
EXCLUSIVE REMEDIES. THIS WARRANTY IS GIVEN IN LIEU OF ALL OTHER EXPRESS
WARRANTIES. IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED
TO THE DURATION OF THIS LIMITED WARRANTY. IN NO EVENT SHALL MOTOROLA BE LIABLE
FOR DAMAGES IN EXCESS OF THE PURCHASE PRICE OF THE ACCESSORY OR FOR ANY
INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY
TO USE SUCH ACCESSORY TO THE FULL EXTENT SUCH MAY BE DISCLAIMED BY LAW:

Some states do not allow the exclusion or limitation of incidental or 
consequential damages, or limitations on how long an implied warranty lasts, so 
the above limitations or exclusions may not apply to you.  This warranty gives 
you specific legal rights, and you may also have other rights which vary from 
state to state.

        This warranty is valid only in the USA.

                                                                     68P09372AB3
