NOTE C - EARNINGS PER SHARE

In February 1997, the Financial Accounting Standards Board issued Statement 
No. 128, Earnings Per Share, which is required to be adopted on December 31, 
1997. At that time, the Company will be required to change the method 
currently used to compute earnings per share and to restate all prior 
periods.  Under the new requirements for calculating primary earnings per 
share, the dilutive effect of stock options will be excluded.  The impact is 
not expected to result in an increase in primary earnings per share for the 
first quarters ended March 31, 1997 and March 31, 1996, respectively.  The 
impact of Statement No. 128 on the calculation of fully diluted earnings per 
share for these quarters is not expected to be material.

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

The following discussion and analysis provides information which management 
believes is relevant to an assessment and understanding of the Company's 
results of operations and financial condition.  The discussion should be read 
in conjunction with the financial statements and notes thereto.

OVERVIEW

To address the wireless communications industry's increasing need for 
products to more effectively combat cloning fraud, a major industry problem, 
the Company has developed the Blackbird-Registered Trademark- Platform and 
related application products and services ("Blackbird Products").  The 
Blackbird Platform has been engineered with an open architecture design to 
allow the Company and others to develop application products which could run 
on or exchange information with it.  Prior to the Company's third quarter of 
1996, revenues had been primarily derived from the Company's 
Hotwatch-Registered Trademark- Platform and related application products and 
services ("Hotwatch Products") and, to a lesser extent, phone rental products 
which are no longer being marketed by the Company.

In 1995, the Company began conducting trials for the purpose of testing and 
evaluating the Blackbird Products.  Since that time, the Company has signed 
agreements with AirTouch Cellular ("AirTouch"), Bell Atlantic NYNEX Mobile 
("BANM"), GTE Mobilnet of California Limited Partnership ("GTE-California"), 
GTE Mobilnet Service Corp. ("GTE Corp") and Ameritech Mobile Communications, 
Inc. ("Ameritech") to deploy and support the Blackbird Products.  During the 
last half of 1996, the Company recorded its first substantive revenues from 
two of these agreements.

Revenue recognition for the Company's systems is based upon performance 
criteria which vary from customer to customer and product to product.  
Physical hardware and software delivery, definitions of system delivery, and 
customer acceptance are generally the significant factors used in determining 
revenue recognition. As a result of such performance criteria, only a portion 
of the systems revenues and the majority of the system costs may be recorded 
during the early stages of a system deployment.  Accordingly, revenues and 
direct margins recorded by the Company can be expected to be lower in earlier 
periods of deployment and inconsistent from quarter to quarter, especially 
during the initial market deployments under new agreements, as was the case 
during the last half of 1996. The resulting deferral of revenue is recognized 
in subsequent periods as the performance criteria specified in the applicable 
agreement is met.

In addition, the Company has incurred substantial operating expenses during 
the early deployments, primarily in the areas of sales and marketing, 
installation and customer support, and in research and development. The 
Company expects that its costs and expenses will continue to increase in the 
future, due to a continual need to make substantial investments in research 
and development, enhanced sales and marketing activities, and expansion of 
customer support capabilities needed to service its anticipated product 
deployments in both domestic and international markets.

The Company's revenue and customer base is currently concentrated among a few 
large domestic cellular carriers due to the significant concentration of 
ownership and/or control of cellular licenses.  As the Company expands its 
domestic and international marketing efforts, and as the wireless 
communications industry expands beyond cellular telephony to include other 
wireless communication services, the Company believes that it will be able to 
diversify its revenue and customer base.  To date, the Company's sales have 
been generated by the Company's in-house sales force.  The Company currently 
uses and expects to continue using agents and/or distributors in conjunction 
with its in-house sales efforts for sales in the international marketplace.  
While the Company has not yet signed international sales agreements, it is in 
the process of exploring and identifying limitations that may be placed upon 
it by foreign operations and the expected resulting impact upon the 

                                    Page 7



Company's results of operations and liquidity.  Its success in exploiting 
these expanded markets and in achieving and maintaining profitability on both 
domestic and international operations, will depend on, among other things, 
its ability to: (i) make its existing and future technology commercially 
acceptable, (ii) recognize and successfully adapt to the rapid changes in the 
wireless communications industry (including digital services), (iii) enhance 
and expand its manufacturing activities concurrent with its growth, (iv) 
comply with foreign regulatory requirements without negatively impacting the 
Company's results of operations or liquidity, (v) manage intellectual 
property protection in foreign countries, (vi) manage foreign currency 
exchange rate fluctuations that may be attributed to international sales 
contracts, and (vii) engage additional sales agents and/or distributors on a 
timely and economic basis.  These and other factors could delay revenues 
and/or increase the cost of doing business.

THREE MONTHS ENDED MARCH 31, 1997 COMPARED TO THREE MONTHS ENDED MARCH 31, 1996

Total revenues increased 2,263% to $17.4 million in 1997 from $.7 million in 
1996 and the Company generated net income of $4.4 million, or $0.19 per share 
in 1997 compared to net loss of $2.5 million, or $0.12 per share in 1996.  
The increase in revenues and resulting net income is directly attributable to 
the Company's deployment and commercial acceptance of its Blackbird Products.

Systems revenues are generated from licensing and sales of the Company's 
proprietary software and hardware products, from the sale of third party 
equipment sold in support of the proprietary systems, and to a lesser extent, 
fees earned associated with the installation and deployment of such systems. 
Systems revenues increased 3,795% to $16.8 million in 1997 from $0.4 million 
in 1996 and represent revenues primarily from Blackbird Products derived from 
sales under the agreements with AirTouch, BANM, GTE-California and Ameritech. 
 There were no corresponding system revenues during 1996.  System revenues 
from Hotwatch Products during the period were minimal and are not expected to 
contribute significantly to revenues in the future.

Service revenues are derived primarily from hardware and software 
maintenance, software upgrades and new releases, No Clone ZoneSM roaming 
protection services, system monitoring and related professional services 
provided in support of the Company's currently deployed product base.  These 
revenues increased 79% to $0.5 million in 1997 from $0.3 million in 1996.  
This increase is directly attributable to growing service revenues 
originating from Blackbird Products that were deployed in late 1996.  The 
Company anticipates that total service revenues during 1997 and beyond will 
continue to increase as a result of continued deployment of the Company's 
Blackbird Products.

Costs of systems and services increased 727% to $8.4 million in 1997 from 
$1.0 million in 1996.  Costs of systems and services are primarily comprised 
of the costs of:  (i) equipment (which primarily includes proprietary and 
third party hardware, and to a lesser extent, manufacturing overhead, and 
related expenses), (ii) amortization of capitalized software development, 
(iii) system integration and installation, (iv) patent royalty fees, and (v) 
customer support.  Costs of equipment totaled $6.0 million in 1997 and were 
primarily related to Blackbird Product deployments.  Such costs for the 
corresponding period in 1996 were minimal.  Cost of software amortization, 
system integration and installation, patent license fees and customer support 
increased 140% to $2.4 million in 1997 from $1.0 million in 1996 and is 
attributable primarily to increased personnel and related overhead costs 
associated with installing and supporting products in the Company's expanded 
customer base.

Costs of systems and services, as a percent of total revenues, were 48% and 
138% for the 1997 and 1996 periods, respectively.  The improvement in 1997 is 
attributable to an increased volume of system sales, where direct margins 
exceeded fixed costs of systems and services, which was not the case in 1996.

                                    Page 8



Sales and marketing expenses increased 70% to $1.4 million in 1997 from $0.8 
million in 1996.  This increase is primarily attributable to personnel and 
related costs incurred in connection with the Company's increased efforts to 
generate demand for its products and the costs incurred during both pre- and 
post-sales contract activities related to the Blackbird Products.  To a 
lesser extent, variable sales incentive compensation contributed to the 1997 
increased expenses.

General and administrative expenses increased 75% to $0.9 million in 1997 
from $0.5 million in 1996 principally due to increased personnel related 
costs associated with the continued expansion of the Company's business, and 
to a lesser extent, incentive compensation accruals that would be payable 
upon achievement of annual financial and operating goals.

Research and development expenditures include the costs for research, design, 
development, testing, preparation of training and user documentation, and 
fixing and refining features for the software and hardware components 
included in the Company's current and future product lines.  Research and 
development costs increased 135% to $2.3 million in 1997 from $1.0 million in 
1996.  Software development costs of $0.4 million were capitalized during 
each period for 1997 and 1996 and related to the development of the Blackbird 
Products. Capitalized development costs did not increase in 1997 at the same 
rate as did research and development expenses primarily due to an increase in 
the non-capitalizable research, design, and maintenance activities associated 
with the Blackbird Products either deployed or new and/or enhanced products 
in the research and design stages.  Including capitalized software 
development costs, gross research and development expenditures increased 93% 
to $2.7 million in 1997 from $1.4 million in 1996, primarily due to expanded 
investment in the Blackbird Products.

Interest income decreased 55% to $0.05 million in 1997 from $0.1 million in 
1996.  The decrease was attributable to lower average cash balances invested 
at lower average interest rates during 1997 as compared to 1996.

LIQUIDITY AND CAPITAL RESOURCES

The Company's capital requirements have consisted primarily of funding 
software development, property and equipment requirements, working capital 
and the Company's operating losses in prior periods.  The Company has 
historically funded these requirements through issuance of Common Stock 
(including proceeds from the exercise of warrants and options) and from 
operating profits in certain periods.  On March 31, 1997 the Company's cash 
balance was $4.7 million as compared to $4.9 million on December 31, 1996.  
The Company's working capital increased to $15.2 million at March 31, 1997 
from $11.4 million at December 31, 1996.

Cash provided by operating activities amounted to $1.1 million in 1997, as 
compared to cash used by operating activities of $3.5 million in 1996.  The 
major factor contributing to the Company's cash flow from operating 
activities is the profit recorded in 1997 and the loss incurred in 1996.  
Depreciation and amortization, which provides cash for operating activities, 
increased moderately and is attributable to the increased investment in 
software development and property and equipment as discussed below.  In 
addition, the net changes in the balances of the major working capital 
components impacted cash flow from operating activities and included: (i) 
accounts receivable, which increased in 1997 as a result of Blackbird System 
revenues recorded during the first three months of the year, (ii) 
inventories, which decreased in response to sales demand for Blackbird 
Products during 1997, (iii) accounts payable, which decreased due to payments 
made for inventory purchases in late 1996, (iv) deferred revenue, which 
increased primarily as a result of the growth of prepaid maintenance and 
service contracts related to the Blackbird system sales, and (v) customer 
deposits, which decrease reflects revenues associated with initial sales to 
new customers that were recorded subsequent to cash received.  During the 
early stages of deploying the Blackbird Products, the Company has experienced 
uneven cash flow and operating 

                                    Page 9



results.  These factors originate from the deferred revenue recognition and 
payment terms contained in customer agreements.

Cash utilized by investing activities totaled $1.2 million and $0.6 million 
in 1997 and 1996, respectively.  The Company's capital requirements during 
such periods were (i) software development of the Blackbird Products and (ii) 
property and equipment, primarily for furniture, leaseholds, and equipment 
associated with expanding the Company's business.  These expenditure levels 
are expected to continue in 1997 at or above the current levels.  At March 
31, 1997, the Company had no significant commitments for capital 
expenditures.  The Company, as part of its growth strategy, would consider 
the cost/benefit of purchasing software and/or hardware technology in the 
event that an attractive opportunity arises.

Cash provided by financing activities (exercise of stock options by the 
Company's directors, officers and employees) totaled $0.02 million and $0.4 
million during 1997 and 1996, respectively.

In November 1996, the Company sold 400,000 shares of common stock to 
investors in a private placement with proceeds to the Company approximating 
$6.4 million net of estimated expenses.  A registration statement for the 
resale of such shares was declared effective by the Securities and Exchange 
Commission in April 1997.  Also, in November 1996, the Company obtained a 
$5.0 million line of credit from a major bank.  The line, which is secured by 
all personal property of the Company, bears interest at the prime rate plus 
 .75% and expires September 30, 1997.  The proceeds from the stock sale and 
the line of credit will be used to fund the Company's growth and provide 
additional working capital.  No funds have been drawn on the line of credit 
as of this date.

The Company expects to continue to incur substantial expenses in (i) support 
of research and development activities, (ii) growth of its sales and 
marketing organization, (iii) support for new products and the anticipated 
expanded customer base, (iv) enhancing the hardware design and manufacturing 
processes, and (v) administrative activities.  The Company believes that cash 
flow anticipated from its operating activities, existing cash balances and 
cash available under its line of credit, are sufficient to fund its 
operations for at least the next 12 months.
