                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                 Nine Months  Ended September 30, 1996 and 1995

                                   (Unaudited)
1.  BASIS OF PRESENTATION

          These financial statements are unaudited; however, the information
     contained herein for STM Wireless, Inc. (the "Company", or "STM") gives
     effect to all adjustments (which are normal recurring accruals) necessary,
     in the opinion of Company management, to present fairly the financial
     statements for the interim periods presented.


          The results of operations for the current interim period are not
     necessarily indicative of the results to be expected for the current year.

          Although the Company believes that the disclosures in these financial
     statements are adequate to make the information presented not misleading,
     certain information and footnote disclosures normally included in financial
     statements prepared in accordance with generally accepted accounting
     principles have been condensed or omitted pursuant to the rules and
     regulations of the Securities and Exchange Commission (the "SEC"), and
     these financial statements should be read in conjunction with the financial
     statements included in the Company's Annual Report on Form 10-K for the
     year ended December 31, 1995, which is on file with the SEC.

1.   DISCONTINUED OPERATIONS

          Effective March 31, 1996 the Company sold its RF Microsystems
     subsidiary to Remec, Inc. for cash in the amount of $2,926,000.  The gain
     on the sale has been accounted for as discontinued operations and prior
     period financial statements have been restated to reflect discontinuance of
     this segment of the business.  A summary of operating results for
     discontinued operations is shown below:

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

     At December 31, 1995, inventories included $2,881,000 related to
     discontinued operations which are classified separately in the consolidated
     balance sheet as part of  "Net assets of discontinued operations".

4. INCOME PER COMMON AND COMMON EQUIVALENT SHARE

          Income per share of common stock is computed using the weighted
     average number of common and common equivalent shares of stock outstanding
     during the period.  Common stock equivalents consist of dilutive
     outstanding stock options and warrants and are calculated using the
     treasury stock method.  Primary income per share approximates fully diluted
     earnings per share for all periods presented.

5. RECLASSIFICATIONS

          Certain reclassifications have been made to the 1995 consolidated
     financial statements to conform to the 1996 presentation.

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

GENERAL

     The Company develops, manufactures and markets satellite and wireless
communication products including VSATs (very small aperture terminals),
transceivers, modems, and other networking equipment.  The Company's proprietary
hardware and software are designed to support data, fax, voice, and video
networks requiring cost effective connections between geographically dispersed
locations. The majority of the Company's revenue is generated in the
international market through foreign distributors and sales representatives.
The Company's customers include government agencies, telephone companies, multi-
location corporations and others.

      Effective March 31, 1996, the Company sold all the outstanding common
stock of  RF Microsystems, Inc., its wholly owned subsidiary, to Remec, Inc. for
$2,926,000 cash. The Company also entered into a Technology Purchase Agreement
on March 31, 1996, whereby the Company sold certain of its technologies, which
were not part of the RF Microsystems segment, to Remec, Inc. for $1,000,000
cash.  In addition, the Company entered into Development, Manufacturing and
Product Supply Agreements which establish Remec, Inc. as the provider of certain
components that are incorporated into the Company's products utilizing the
aforementioned technologies for a term of at least two years.  The agreements
also provide for joint development of other products by the Company and Remec,
Inc. and purchase of such products by the Company from Remec, Inc. at specified
market prices.

RESULTS OF OPERATIONS

RESULTS OF CONTINUING OPERATIONS

     Combined product and service revenues were $7,882,000 and $25,184,000,
respectively, for the three and nine-month periods ended September 30, 1996,
compared to $7,113,000 and $23,029,000, respectively, for the corresponding
periods of 1995, representing increases of 11% and 9%, respectively, over the
prior year periods.  Product revenues were $7,323,000 and $22,939,000,
respectively, for the three and nine-month periods ended September 30, 1996,
compared to $6,320,000 and $20,004,000, respectively, for the corresponding
periods in 1995, representing increases of 16% and 15%, respectively, over the
prior year periods. The product revenue increases were due to the sale of
technology to the purchaser of the Company's RF Microsystems subsidiary in the
first quarter, and to shipments related to the Company's major contracts
throughout the three and nine-month periods. Product revenues for the three
month period ended September 30, 1996 were adversely impacted by the reversal of
$2,132,000 of net sales to a customer in Brazil which was previously recognized
as revenue in the third quarter 1995.  The reversal was the result of the
Company's decision to rescind the sale and refund the original deposit made by
the customer due to changed economic and regulatory conditions in Brazil, which
made the use of the network provided no longer economically


                                        8

<PAGE>

viable for the customer.  The Company believes its decision to rescind this
sale rather than pursuing legal remedies is in the long-term best interests of
the Company as it will enable the Company to maintain its good standing in the
Brazilian market and allow it to capitalize on anticipated Brazilian market
opportunities.  Service  revenues were $559,000 and $2,245,000, respectively,
for the three and nine-month periods ended September 30, 1996, compared to
$793,000 and $3,025,000, respectively, for the corresponding periods in 1995,
representing decreases of 30% and 26%, respectively, from the corresponding
periods of 1995.  Program management services for both of the comparable
periods in 1995 were bolstered by a relatively large contract, not representing
core business, to provide services to a Malaysian customer in connection with
the design, procurement, and supervision of a personal communications service
(PCS) network.  The contract was completed in 1995.

     Combined product and service gross profit margins in the three and nine-
month periods ended September 30, 1996, were 44% and 41%, respectively, compared
to 49% and 39%, respectively,  for the comparable periods in 1995. Product gross
profit margins in the three and nine-month periods ended September 30, 1996,
were 44% and 39%, respectively, compared to 49% and 36%, respectively, for the
comparable periods in 1995.  The decrease in profit margins in the three-month
period was primarily due to the impact of the above-mentioned reversal of a sale
in the previous year to a customer in Brazil. Profit margins in the comparable
nine-month period in 1995 suffered primarily due to the Company acting as an
integrator in providing Standard A Earth Stations to a customer in Malaysia.
Product integration generally yields a lower gross profit margin than product
manufacturing. Service gross profit margins in the three and nine-month periods
ended September 30, 1996, were 47% and 58%, respectively, compared to 53% and
59%, respectively,  for the comparable periods in 1995. Profit margins for both
periods were within the Company's expectations based on historical experience.
During the comparable periods in 1995, the Company was providing services to a
customer in Malaysia in connection with a PCS network, which provided higher
gross profit margins than the Company's historical services.

     Selling, general, and administrative expenses for the three-month period
ended September 30, 1996, increased to $1,792,000 from $1,410,000, and increased
slightly as a percentage of revenue from 20% to 23%.   For the nine months ended
September 30, 1996, such expenses increased to $4,665,000 from $4,095,000, but
remained flat as a percentage of revenue at 18%. The dollar increases in
expenditures in both periods in 1996 were the result of an increase in expenses
to support the Company's growth in core product revenues.

     Research and development expenses for the three-month period ended
September 30, 1996, increased to $1,685,000, or 21% of revenues, from
$1,000,000, or 14% of revenues, in the corresponding period of 1995.  For the
nine-month period ended September 30, 1996, such expenses increased to
$4,650,000, or 19% of revenues, from $2,486,000, or 11% of revenues, in the
corresponding period in 1995. The planned increases in expenditures for both
periods were for additional personnel and outside services, both in STM and the
Company's TMSI subsidiary, to support strategic new



                                        9

<PAGE>

product development which the Company believes will lead to penetration of new
product markets.

     Interest income increased by $155,000 to $206,000 for the three-month
period ended September 30, 1996.  Interest income increased by $249,000 to
$765,000 for the nine-month period ended September 30, 1996, over the nine-month
period ended September 30, 1995. The increases in both periods were due to the
recognition of interest income related to a long-term lease receivable in
Brazil.

     Interest expense increased by $169,000 to $197,000 for the three-month
period ended September 30, 1996, over the three-month period ended September 30,
1995.  Interest expense increased by $255,000 to $528,000 for the nine-month
period ended September 30, 1996, over the nine-month period ended September 30,
1995.  The increases were primarily due to interest expense incurred as a result
of the Company's increased utilization of its secured and unsecured lines of
credit.

DISCONTINUED OPERATIONS

     Effective March 31, 1996 , the Company sold all the outstanding common
stock of  RF Microsystems, Inc., its wholly owned subsidiary, to Remec, Inc. for
$2,926,000 cash.  A summary of operating results for discontinued operations is
shown below:

LIQUIDITY AND CAPITAL RESOURCES

     For the first nine months of 1996, the Company had negative cash flows from
operations of $3,248,000, compared to positive cash flows of $1,071,000 in the
same period of 1995. The decrease in cash flows was primarily due to increased
investments in  receivables and inventories, partially offset by increased
accounts payable, the sale of net assets of discontinued operations, and net
income. Working capital increased to support the Company's continued growth into
new markets with new products.

     Cash provided by investing activities in the first nine months of 1996
totaled $638,000. Sales and maturities of short-term investments exceeded
purchases of such investments by $1,200,000.  The acquisition of fixed assets
used $562,000 of cash.

     Cash flows from financing activities during the first nine months totaled
$6,331,000 and included net bank borrowings of $4,800,000. The Company paid down
and terminated its $3,000,000 unsecured line of credit with Wells Fargo Bank and
entered


                                       10

<PAGE>

into an agreement with Wells Fargo HSBC Trade Bank N.A. (Trade Bank) for a
secured $5,000,000 line of credit, of which $4,800,000 had been utilized at
September 30, 1996.  Subsequent to September 30, 1996, the agreement with Trade
Bank was amended to increase the line to $10,000,000.  Further, the Company
borrowed an additional $500,000, secured by the Company's certificates of
deposit in the same amount, from another bank. Proceeds from issuance of common
stock related to the exercise of stock options totaled $96,000.  A net increase
of long-term debt provided $199,000.

     Overall, the Company's cash, cash equivalents and short-term investments
totaled $11,616,000 at September 30, 1996, as compared to $9,095,000 at December
31, 1995. The Company believes it has adequate capital resources to meet its
current working capital requirements and capital expenditure commitments for at
least the next 12 months, including the expansion of its international marketing
and sales efforts, and the purchase of additional capital equipment for
manufacturing and research and development.

POSSIBLE VOLATILITY OF STOCK PRICES

     The market prices for securities of technology companies, including the
Company, have been volatile.  Quarter to quarter variations in operating
results, changes in earnings estimates by analysts, announcements of
technological innovations or new products by the Company or its competitors,
announcements of major contract awards, changes in foreign political or
regulatory environments, and other events or factors may have significant impact
on the market price of the Company's common stock.  In addition, the securities
of many technology companies have experienced extreme price and volume
fluctuations, which have often been unrelated to the Company's operating
performance.  These conditions may adversely affect the market price of the
Company's stock.

FORWARD LOOKING STATEMENTS

     This report contains certain forward looking statements that involve risks
and uncertainties.  Certain risks and uncertainties which may impact the
accuracy of forward looking statements with respect to revenues, expenses and
operating results may include, without limitation, long-term cycle involved in
completing major contracts, particularly in foreign markets, increasing
competitive pressures, general economic conditions, technological advances, the
timing of new product introductions, political and economic risks involved in
foreign markets and foreign currencies and the timing of operating and other
expenditures.

     Because of time and other factors affecting the Company's operating
results, past historical performance should not be  used as an indicator of
future performance, and investors should not use historical trends to anticipate
results or trends in future periods.
