ITEM 1.   BUSINESS

     Unless the context otherwise requires, all references to the "Company"
herein refer to U.S. Digital Communications, Inc. ("U.S. Digital") and its
wholly-owned subsidiary U.S. Digital Satellite, Inc. ("Insat") and Insat's two
wholly-owned subsidiaries, Skysite Communications Corp. ("Skysite") and Project
77 Corp. ("Project 77").  On October 24, 1997, U.S. Digital changed its name
from Viscorp.

BACKGROUND

     U.S. Digital Communications, Inc. is a telecommunications industry company
based in Chevy Chase, Maryland.  The Company is primarily a global satellite
communications firm that specializes in corporate applications. Specifically,
the Company is a provider of satellite telephone subscriber equipment and
services.

     Visual Information Services Corp. was originally incorporated in Illinois
in May 1990, and was founded to develop an electronic device capable of adding
modem, video data and telephone features to an ordinary television receiver over
a telephone line.  On November 28, 1995, shareholders of Visual Information
Services Corp. acquired the outstanding shares of Global Telephone and
Communications, Inc., a Nevada corporation ("GTCI"), in exchange for their
shares of Visual Information Services Corp. (the "Transaction").  GTCI was
incorporated in May 1984 to provide consulting services for the public and
private sectors. To the Company's knowledge, GTCI never operated as a consultant
nor carried on any type of business at any time prior to the Transaction.  The
Transaction was consummated because the common stock of GTCI traded on the
Nasdaq Bulletin Board, and thus, the Transaction provided the Company an entity
with an existing public presence.  Pursuant to the Transaction, each share of
Common Stock of Visual Information Services Corp. was exchanged for four shares
of common stock of GTCI.  Following the Transaction, GTCI changed its name to
Viscorp.

     Between November 1995 and August 1997, the Company developed two products:
the Universal Internet Television Interface Device ("UITI") and the Electronic
Device ("ED").  UITI is a technology  designed to give the home television
viewer access to the Internet, World Wide Web and other on-line services.  ED is
a device which, in addition to on-line services, was designed to feature such
capabilities as telephone reception and dial-up, facsimile, pay-per-view options
and electronic mail.  The Company has decided not to take any further steps to
develop this technology or to market these products.  For the year ended
December 31, 1997, there was no revenue from the sale of these products.  The
Company is not aware of any market for this technology, and does not expect to
realize any revenue therefrom.  On September 1, 1998, pursuant to a settlement
agreement with Raquel Velasco, the Company granted Ms. Velasco an option to
purchase the ED and UITI technologies, in addition to certain other property,
for a total consideration of $50,000.  See "--Legal Proceedings."

     In May 1997, U.S. Digital became involved in operating Skysite
Communications Corporation.  Skysite was initially created to market a new
satellite-based telecommunications system called Mobilesat, or MSAT (MSAT is a
trademark term used as an abbreviation by the American Mobile Satellite
Corporation in the United States).

     On June 20, 1997, the Company entered into an Agreement and Plan of
Reorganization with Intercontinental Technologies Group, Tom D. Soumas, Jr.,
Cochran Ranch Golf and Tennis Resort, Sinai Administrative Trust, Carol
Anderson, Howard Garber, George Straayer (the "Selling Shareholders") and
Skysite.  Under the Agreement, the Company was to issue 750,000 shares of its
common stock to the shareholders of Skysite, as well as options to purchase an
additional 500,000 shares of its common stock at an exercise price of $.40 per
share,  in exchange for 100% of the outstanding shares of common stock of
Skysite.

     The stock of Skysite was transferred to the Company on August 26, 1997.
Subsequent to the acquisition, disputes arose between the Company and the former
President of Skysite, Tom D. Soumas, related to the value of Skysite at the time
of the acquisition.  As a result of the dispute, the Company withheld its
shares.  On May 28, 1998, the Company entered into an amended agreement with the
Selling Shareholders, except for Tom D. Soumas.  Under the terms of the amended
agreement, the other shareholders' shares and options will be placed in an
escrow account. The shareholders will have all rights attributable to these
escrowed shares, however, they have agreed that at such time when they elect to
sell these shares, the first $200,000 of related proceeds will be paid to the
Company, and the remaining shares and options will be released to the other
Shareholders.  The 240,000 shares due to Mr. Soumas under the original agreement
remain unissued, and the Company does not intend to issue such shares.  No
shares or options for the other Selling Shareholders have been issued or placed
in escrow as of October 6, 1998.

                                       2

     On October 24, 1997, Viscorp changed its name to U.S. Digital
Communications, Inc.  In connection with the acquisition of Skysite, the sellers
of Skysite incurred an obligation to pay a broker's commission of options to
purchase 200,000 shares of U.S. Digital at $0.40 per share to be paid from
the 500,000 options issued to them by the Company.  In July 1998, the Company
created Insat to oversee its satellite communications operations and transferred
the common stock of Skysite to Insat and incorporated Project 77 as Insat's
other wholly-owned subsidiary.

GENERAL

     In addition to its corporate offices in Chevy Chase, Maryland, the Company
has operations in Burbank, California, and Washington, D.C.  The Company,
through Insat, markets satellite and wireless digital communications equipment
and services.  Skysite operates as the marketer of satellite telephone products
and services and Project 77 specializes in Iridium satellite personal
communications technology.  The Company, through its subsidiaries, works closely
with satellite telephone manufacturers and systems operators to provide
solutions to communications needs of international business travelers and
companies with global, emergency and/or remote operations.

     While the Company has developed a revenue stream from satellite telephone
customers over the past two years, it is still in a development stage and has
not been profitable.  The satellite telephony industry is still in its infancy
and the eventual profitability of the Company will be dependent on the
acceptance of the new communications technologies it will provide.  The Company
is preparing to expand its current product offerings upon the proposed
commercialization of the Iridium global satellite system prior to the end of
1998.  See "Risk Factors--Dependence on Certain Suppliers."

     Domestically, the Company is exploring opportunities to acquire companies
with existing corporate and customer bases within its niche markets, which
include the media, government, oil exploration, transportation and disaster
recovery.   The Company also seeks to increase its global presence through the
acquisition of suitable companies located in other major markets outside of the
United States.  On April 8, 1998, the Company entered into a non-binding
memorandum of understanding with Eurotelecom Communications, Inc., a Delaware
corporation, to purchase all of the issued and outstanding shares of Eurotelecom
("Eurotelecom") in exchange for approximately 1.7 million shares of the
Company's common stock.  As a part thereof, the Company agreed to provide up to
$1.0 million to Eurotelecom for operating expenditures.  Eurotelecom owns 100%
of Eurotelecom Corporation Limited, incorporated in England and Wales, which, in
turn, owns 100% of the stock of Eurotelecom Secure Networks Limited, also
incorporated in England and Wales.  The memorandum of understanding also
provided for employment agreements with key employees which were to include
shares of the Company's common stock as part of the compensation terms.  A
condition to the closing was the acquisition by Eurotelecom of Optilan (UK)
Limited, Easy-IP Limited and Intelligent Networks, Limited, all incorporated in
England and Wales.  It was also the parties' intention that Eurotelecom be
represented on the Company's Board of Directors.  In May 1998 and in August
1998, the Company loaned $260,000 and $250,000, respectively, for a total of
$510,000, to Eurotelecom for operating expenses.

     On August 4, 1998, the Company terminated the memorandum of understanding
with Eurotelecom due to a change in the proposed structure of the acquisitions.
The Company is negotiating with EuroTelecom Corporation Limited, the wholly-
owned subsidiary of Eurotelecom, to purchase all of the issued and outstanding
shares of Eurotelecom Secure Networks Limited, Optilan Limited, Easy IP Limited
and Intelligent Networks Limited. However, such negotiations have stalled, and
the Company does not know whether the acquisitions will take place. EuroTelecom
Corporation Limited has agreed to repay the outstanding loans in accordance with
their terms. The Company and EuroTelecom Corporation Limited have not entered
into an agreement and there can be no assurance that such acquisition will take
place.

                                  RISK FACTORS

     The Company may from time to time make written or oral forward-looking
statements.  Written forward-looking statements may appear in documents filed
with the Securities and Exchange Commission (the "Commission"), in press
releases, and in reports to shareholders.  The Private Securities Litigation
Reform Act of 1995 contains a safe harbor for forward-looking statements on
which the Company relies in making such disclosures.  Forward-looking statements
can be identified by the use of words such as "believes," "anticipates,"
"plans," "expects," "may," "will," "intends," "estimates" and the negatives
thereof and similar expressions.  In connection with this "safe harbor," the
Company is hereby identifying important factors that could cause actual results
to differ materially from those contained in any forward-looking statements made
by or on behalf of the Company.  Any such statement is qualified by reference to
the following cautionary statements.

DEVELOPMENT STAGE COMPANY; HISTORY OF OPERATING LOSSES; FUTURE CAPITAL NEEDS

     The Company is a development stage company.  The Company has incurred
significant operating losses in every fiscal period since inception.  In August
1997, in connection with the acquisition of Skysite, the Company terminated its
production of the UITI and ED technologies and concentrated its business on the
global satellite communications market.  Skysite was incorporated in August 1995
and has only limited operating history.  The Company is thus subject to the
risks inherent in the establishment and growth of a new business enterprise.
The likelihood of success of the Company must be considered in light of the
problems, expenses, difficulties and delays frequently encountered in connection
with a new business, including, but not limited to, a continually evolving
industry subject to rapid technological and price changes, acceptance of the
products that Skysite markets and an increasing number of market competitors.
For the year ended December 31, 1997, the Company's operating loss was
$5,144,888. The Company expects to incur substantial quarterly operating losses
through 1998 and possibly longer.

     In order to become profitable, the Company must successfully market and
sell its satellite telephone products and services, sell evolving products for
new and existing markets, increase gross margins through higher sales volumes,
expand its distribution capability and manage its operating expenses.  There can
be no assurance that the Company will ever achieve those objectives or
profitability.  The Company's actual working capital needs depend upon numerous
factors, including the extent and timing of acceptance of the Company's products
in the market, the Company's operating results, the cost of increasing the
Company's sales and marketing activities and the status of competitive products,
none of which can be predicted with certainty.  As a result, there can be no
assurance that the Company will not require additional funding.  There can be no
assurance that any additional financing will be available to the Company on
acceptable terms, or at all, when required by the Company.  The inability to
obtain such financing would have a material adverse effect on the Company's
business, financial condition and results of operations.  The Company could be
required to significantly reduce or suspend its operations, seek a merger
partner or sell additional securities on terms that are highly dilutive to
shareholders.  The type, timing and terms of financing amounts selected by the
Company will be dependent upon the Company's cash needs, the availability of
other financing sources and the prevailing conditions in  the financial markets.
For the year ended December 31, 1997, the Company raised $4,306,944 million  in
equity offerings.  See "--Significant Dilutive Effects of Shares Eligible for
Future Sale on Market Price of Common Stock," "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and Capital
Resources" and Financial Statements.

RAPID TECHNOLOGICAL CHANGE; DEPENDENCE ON PRODUCT DEVELOPMENT

     The market for satellite telephone products is characterized by rapidly
changing technology, frequent new product introductions and other changes.
Accordingly, the Company's success will be substantially dependent on a number
of factors, including its ability to identify emerging standards in the
satellite telephone markets, to differentiate the products it sells from those
of its competitors, and to bring those products to market quickly.  Given the
emerging nature of the satellite telephone market, there can be no assurance
that the Company's products or technology will not be rendered obsolete by
alternative technologies.  Furthermore, short product life cycles expose the
Company's products to the risk of obsolescence and require frequent new product
introductions.  The satellite telephone market is extremely competitive and is
characterized by rapidly advancing technology, frequent changes in user
preferences and frequent product introductions.  The future success of the
Company will depend in large part on its ability, and that of its product
suppliers, to keep pace with advances in technologies for the satellite
telephone market.  There can be no assurance that the Company will be able to
identify, market or support such products successfully or that it will be able
to respond effectively to technological changes or product announcements by
competitors.  The Company is unable to predict which of the many possible future
products and services will meet evolving industry standards and consumer
demands. Delays in response by the Company could have a material adverse effect
on the Company's business, financial condition and results of operations.

                                       4

COMPETITION

     The wireless communications industry is highly competitive and is
characterized by frequent technological innovation.  The industry includes major
domestic and international companies, many of which have financial, technical,
marketing, sales, distribution and other resources substantially greater than
those of the Company and which provide, or plan to provide, a wider range of
services.  The Company's products and services compete with a number of
communications services, including existing satellite services, terrestrial air-
to-ground services, and terrestrial land-mobile and fixed services, and may
compete with new technologies in the future.  In addition, the Federal
Communications Commission ("FCC") has recently allocated large amounts of
additional spectrum for communications uses or potential uses that could compete
with the Company, and additional allocations of spectrum for such uses may occur
in the future.  There can be no assurance that the Company will be able to
compete successfully with such companies.  See "Business-Competition."

DEPENDENCE ON CERTAIN SUPPLIERS

     The Company is supplied satellite services pursuant to an agreement with
American Mobile Satellite Corporation and intends to be supplied satellite
services prior to the end of 1998 pursuant to an agreement with Iridium U.S.,
L.P. ("Iridium").  Currently, the Company is supplied satellite services
primarily by American Mobile Satellite Corporation.  The Company is a
nonexclusive dealer for manufacturers of satellite telephones, which include
Westinghouse Electric ("Westinghouse") and Mitsubishi Electronics America, Inc.
("Mitsubishi").  For the year ended December 31, 1997, retail sales by the
Company of Westinghouse products and services accounted for approximately 56% of
the Company's revenues.  Since a material amount of the Company's revenues are
derived from selling air time, the unavailability of products would have a
material adverse effect on the Company's business and prospects.  The limited
number of manufacturers is a risk of the Company's business.  The loss of any
supplier could have a material adverse affect on the Company's business,
financial condition and results of operations.  Furthermore, there can be no
assurance that current suppliers will continue to provide products to the
Company at attractive prices, or at all, or that the Company will be able to
obtain such products in the future from these or other providers on the scale
and within the time frames required by the Company.  Also, there can be no
assurance that Iridium will begin to supply satellite services to the Company
within the time frame currently projected.  Further, there can be no assurance
that any of the Company's suppliers will not enter into exclusive arrangements
with the Company's competitors, or cease selling these components to the Company
at commercially reasonable prices, or at all.  Any failure to obtain such
products on a timely basis at an affordable cost, or any significant delays or
interruptions of supply, would have a material adverse effect on the Company's
business, financial condition or results of operations.

DEPENDENCE ON KEY CUSTOMERS

     During the year ended December 31, 1997, the Company's net sales to its
five largest customers accounted for approximately 40% of total net sales.  For
the year ended December 31, 1997, the Royal Bahamas Police Force represented 22%
of the Company's net sales.  Other than the foregoing, no one customer accounted
for 10.0% or more of net sales for the period.  In addition, the satellite
telephone market experiences rapidly changing technology and frequent new
product introduction which may result in loss of customers or uncollectiblity of
accounts receivables of any major customer. As of December 31, 1997, HMS Marine
Services represented 11% of trade receivables.  Other than the foregoing, no one
customer accounted for 10.0% or more of trade receivables.  The loss of or
significant decrease in sales to any one of the Company's major customers or
uncollectability of any accounts receivable of any major customer could have a
material adverse effect on the Company's business, financial condition and
results of operations.

DEPENDENCE ON KEY PERSONNEL

     The Company is dependent upon its executive officers and certain key
employees, the loss of any one of whom could have a material adverse effect on
the Company's business, financial condition and results of operations. The
Company's future success will depend in significant part upon the continued
service of certain key personnel, and the Company's continuing ability to
attract, assimilate and retain highly qualified managerial and sales and
marketing personnel. There can be no assurance that the Company can retain its
existing key managerial or sales and marketing personnel or that it can attract,
assimilate and retain such employees in the future. The loss of key personnel or
the inability to hire, assimilate or retain qualified personnel in the future
could have a material adverse effect upon the Company's business, financial
condition or results of operations. The Company does not have employment
contracts with its officers and key employees. Moreover, the Company does not
have key-man life or disability insurance on any of its officers or key
employees. In the event of their death or disability or in the event they are
otherwise unable to render services to the Company, there can be no assurance
that the Company will be able to recruit and retain replacements. See
"Management--Directors and Executive Officers."

MANAGEMENT OF GROWTH

     Depending on the extent of its future growth, the Company may experience a
significant strain on its management, operational and financial resources.  The
Company's ability to manage its growth effectively may require it to continue to
implement and improve its operational and financial systems and may require the
addition of new management personnel.  The failure of the Company's management
team to effectively manage growth, should it occur, could have a material
adverse impact on the Company's business, financial condition or results of
operations.  See "Management's Discussion and Analysis of Financial Condition
and Results of Operations," "Business--Employees" and "Management."

UNCERTAINTY OF ACQUISITION OPPORTUNITIES

     The Company believes that it will achieve significant competitive
advantages by expanding its geographic and products markets through
acquisitions. The availability of suitable companies on economically acceptable
terms is uncertain.  The Company's growth could be affected unfavorably if it
cannot implement its acquisition strategy.

VOLATILITY OF STOCK PRICE

     There can be no assurance that a public market for the Company's Common
Stock will be sustained.  In the absence of such a market, purchasers of the
Common Stock may experience substantial difficulty in selling their securities.
The trading price of the Company's Common Stock may be, and has been, subject to
significant fluctuations in response to variations in quarterly operating
results, announcements of technological innovations by the Company or its
competitors, general conditions in the satellite telephone market and other
factors.  In addition, the stock market is subject to price and volume
fluctuations that affect the market prices for companies in general, and small
capitalization companies in particular.  See "Market For Registrant's Common
Equity and Related Shareholder Matters."

ILLIQUIDITY OF TRADING MARKET; RISK OF PENNY STOCK STATUS

     The Company's Common Stock is traded on the OTC Bulletin Board.
Consequently, the liquidity of the Common Stock has been in the past, and could
be in the future, impaired, not only in the number of shares of Common Stock
which could be bought and sold, but also through delays in the timing of the
transactions, reductions in security analysts' and the news media's coverage of
the Company, and lower prices for the Common Stock than might otherwise be
attained.  The Company will be subject to the Commission's "penny stock" rules.
Securities are exempt from this rule if, among other things, the market price is
at least $5.00 per share.  Consequently, an investor will find it more difficult
to dispose of, or to obtain accurate quotations as to the price of, the
Company's securities.  The "penny stock" rules under the Securities Exchange Act
of 1934, as amended, impose additional sales practice and market-making
requirements on broker-dealers who sell and/or make a market in such securities.
For transactions covered by the penny stock rules, a broker-dealer must make
special suitability determinations for purchasers other than established
customers and must have received the purchasers' written consent to the
transactions prior to sale.  In addition, prior to any transaction involving a
penny stock, unless exempted, the rules require delivery of a disclosure
schedule to the Commission relating to the penny stock.  Disclosure is also
required to be made about commissions payable to both the broker-dealer and the
registered representative and current quotations for the securities.  Finally,
monthly statements are required to be sent disclosing recent price information
for the penny stock held in the account and information on the limited market in
penny stocks.  The rules on penny stocks could affect the ability or willingness
of broker-dealers to sell and/or make a market in the Company's securities and
therefore could severely adversely affect the market liquidity for the Company's
securities.  See "Market for Registrant's Common Equity and Related Shareholder
Matters."

INDICTMENT OF WS MARKETING AND FINANCIAL SERVICES, INC.

     In September 1998, the Company became aware that persons associated with WS
Marketing and Financial Services, Inc., the placement agent for the Company's
Series B and Series C Preferred Stock, are currently under Federal indictment
concerning matters unrelated to WS Marketing and Financial Services, Inc.'s
relationship with the Company. The criminal indictment, filed in the United
States District Court, Southern District of Texas, Houston Division, Criminal
No. H-97-262-SS, includes allegations of conspiracy, wire fraud and money
laundering. There can be no assurance that the foregoing indictment will not
affect the Company's liquidity or capital resources. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."

     As of October 6, 1998, there were 735,000 shares of Common Stock issuable
upon the exercise of options under the Company's 1996 Non-Employee Directors'
Stock Option Plan and the 1998 Stock Option, Deferred Stock and Restricted Stock
Plan. In addition, as of October 6, 1998, there were 1,910,200 shares of Common
Stock issuable upon the exercise of options under the stock option plan adopted
by the Company in 1995. See "Executive Compensation-Stock Option Plans."
Finally, as of October 6, 1998, there were 3,560,400 shares of Common Stock
issuable upon the exercise of options granted outside any of the Company's stock
option plans. Of these options, 2,380,000 options were granted to a placement
agent in connection with the Series A Preferred Stock. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources." In addition, the Company has issued 4,338,832
shares of Series A Preferred Stock, 3,000 shares of Series B Preferred Stock,
and 3,000 shares of Series C Preferred Stock, which are all convertible into
shares of Common Stock. Each share of Series A Preferred Stock is convertible
into one share of Common Stock, whereas each share of Series B and Series C
Preferred Stock is convertible into a number of shares as determined by the
Series B and Series C conversion formula. Holders of Series A Preferred Stock
may convert up to 25% of their shares 90 days following the date the shares were
issued, and up to 25% of their shares at the end of each of the three
consecutive 90-day periods thereafter. Holders of Series A Preferred Stock also
possess conversion rights exercisable upon acquisition of the Company by another
entity. Further, the Series A Preferred Stock is automatically converted into
Common Stock upon the consummation of the Company's sale of its Common Stock in
a firm commitment underwritten public offering, or upon acquisition of the
Company, if, in connection with such acquisition, the holders of Series A
Preferred Stock receive an amount per share greater than $1.50. Holders of
Series B Preferred Stock may convert 50% of their shares into Common Stock on
the effective date of registration of the underlying Common Stock and the
remaining 50% 45 days thereafter. Holders of Series C Preferred Stock have the
right to convert 50% of their shares into Common Stock upon the earlier of the
effective date of registration of the underlying Common Stock, or 120 days after
issuance of the Series C Preferred Stock and the remaining 50% upon the earlier
of 45 days following the effective date of registration of the underlying Common
Stock, or 165 days after issuance of the Preferred Stock. In connection with the
sale of the Series A, Series B and Series C Preferred Stock, the Company issued
2,169,416, 500,000 and 495,000 warrants, respectively, convertible into an
aggregate of 3,164,416 shares of Common Stock. Lastly, in connection with each
of the offerings of the Series B and Series C Preferred Stock, the Company
issued 250,000 warrants, for a total of 500,000 warrants, to the placement agent
thereof. The warrants include certain dilution adjustments resulting from the
subsequent issuance of Common Stock or securities converting into Common Stock.
All of the common shares, to the extent that they are eligible or appear to be
eligible for sale in the public market, could have a material adverse effect on
the market price of the Common Stock and therefore make it more difficult for
the Company to sell equity securities or equity-related securities in the future
at a time and price that the Company deems appropriate.

     The Series B Preferred Stock subscription agreements contain a "put"
provision for Common Stock which allows the Company to raise an additional
$3,000,000.  The provision specifies that 75 days after the effective date of
the registration of additional common shares to be used under this provision,
the Company may sell Common Stock (the "Put Stock") to the Series B subscribers.
The price of the Put Stock is determined by taking the lower of (1) 80 percent
of the lowest closing bid price for the previous 20 trading days prior to
funding or (2) 80 percent of the closing bid price on the day of funding.  The
minimum draw is $250,000 and the maximum draw is $750,000.  If the price of the
Company's Common Stock for the 20 trading days prior to the funding is less than
$1.25 and the average trading volume is less than $300,000 per day for the
previous 20 trading days, the Series B shareholders have the option not to fund
the requested draw.  These minimums increase as the amount of the funds
requested by the Company increase from $250,000 to $750,000.

     The Company has issued in the past, and intends to issue in the future,
additional equity securities in order to fund working capital requirements. To
the extent the Company does so, existing shareholders of the Company will
experience substantial dilution, particularly if the terms of such issuance
include discounts to market prices or the issuance of warrants. In addition, to
the extent the Company issues securities at a discount to the then current
market price, the Company will be required to record a stock compensation
expense of such issuances in its financial statements, which will adversely
affect the Company's operating results for the period in which such stock is
issued. For the year ended December 31, 1997, the Company recorded a stock
compensation expense of $1,349,587 in connection with the issuance of Common
Stock and securities convertible into Common Stock.

     In addition, the holders of Series B and Series C Convertible Preferred
Stock and related warrants are entitled to registration rights with respect to
the shares of Common Stock underlying their respective securities.  Pursuant to
the registration rights agreement between the Company and the holders of Series
B and Series C Preferred Stock, the Company is required to file a registration
statement covering the resale of the shares of the Company's Common Stock,
together with any capital shares issued in replacement of or in exchange for
such Common Shares, issuable or issued upon conversion of the Series B or Series
C Preferred Stock and warrants, pursuant to each offering.  The registration
rights agreements also grant holders piggyback and demand registration rights.
To the extent that such holders convert their existing securities into Common
Stock, following the effective date of the Registration Statement related
thereto,

                                       7
<PAGE>
 
such shares will be immediately eligible to be sold in the public market without
restriction under Rule 144 under the Securities Act of 1933, as amended (the
"Act"), which, given the relatively low trading volumes for the Company's Common
Stock, would likely have a significant depressant effect of the per share market
price of the Company's Common Stock.


YEAR 2000 COMPLIANCE

     The Company is assessing the internal readiness of its computer systems for
handling the year 2000 issue.  The Company expects to implement the systems and
programming changes necessary to address year 2000 issues with respect to its
internal systems and does not believe that the costs of such actions will have a
material adverse effect on its business, financial condition and results of
operations.  Although the Company is not aware of any material operational
issues or costs associated with preparing its internal systems for the year
2000, there can be no assurance that there will not be a delay in, or increased
costs associated with, the implementation of the necessary systems and changes
to address the year 2000 issues, and the Company's inability to implement such
systems and changes in a timely manner could have a material adverse effect on
the Company's business, financial condition and results of operations.

     The Company also relies, directly and indirectly, on external systems of
business enterprises such as brokers, sub-servicers, customers, financial
organizations and governmental entities for accurate exchange of data.  Even if
the internal systems of the Company are not materially affected by the year 2000
issue, the Company could be affected by disruptions in the operation of the
enterprises with which the Company interacts.  Despite the Company's efforts to
address the year 2000 issues' impact on its internal systems and business
operations, there can be no assurance that such impact will not result in a
material disruption of its business or have a material adverse effect on the
Company's business, financial condition or results of operations.

RISKS ASSOCIATED WITH STOCK OPTION GRANTS

     The Company has adopted three stock option plans under which it has granted
options to purchase an aggregate of 2,645,200 shares of the Company's Common
Stock.  See "Executive Compensation--Stock Option Plans."  In addition, the
Company has granted additional options to purchase 3,560,400 shares of Common
Stock outside of any stock option plan.  To date, the shares underlying the
stock options have not been registered with the Commission, or under the
securities laws of any applicable state.  The Company has granted the foregoing
options and permitted the issuance of 670,000 shares of Common Stock upon the
exercise of certain stock options in reliance on the exemption from registration
found in Section 4(2) of the Act or Rules 505 or 506 promulgated thereunder and
similar state securities exemptions.  Section 4(2) of the Act exempts from the
registration requirements of Section 5 of the Act those transactions by an
issuer not involving a public offering.  If it is determined at a later date
that the grant of the aforementioned stock options or the issuance of Common
Stock pursuant to the exercise thereof involved a public offering for which the
Company cannot find an exemption, then the Company will have committed a Section
5 violation, or a violation of similar state securities laws, and may be subject
to suit by shareholders pursuant to Section 12 of the Act or such other similar
state securities laws.  A successful suit under Sections 5 or 12 of the Act or
their state securities law counterparts could have a material adverse effect on
the Company's business, financial condition or results of operations.

                              BUSINESS DESCRIPTION

INDUSTRY BACKGROUND

     The Company operates in the global personal voice, paging and data
communications industry.  Potential customers for the products and services
provided by the industry include international corporations, professionals and
others (i) who travel outside their "home" wireless network's roaming area, (ii)
find it important to be able to make or receive calls, or receive pages, at any
time by means of a single phone or pager number, with a single phone or pager
number or (iii) are located where terrestrial landline or wireless services are
not available or do not offer an attractive or convenient option.

     Global satellite communications systems are designed to address two broad
trends in the communications market: (i) the worldwide growth in the demand for
portable wireless communications; and (ii) the growing demand for communications
services to and from areas where landline or terrestrial wireless service is not
available or accessible.

 
TELECOMMUNICATIONS MARKETS

     The Company believes that its products and services are applicable to six
distinct market segments:

     1.   Transportation;
     2.   Broadcast Media and Motion Picture Industry;
     3.   Disaster Recovery;
     4.   Government and Public Safety;
     5.   Natural Resource Extraction-Petroleum, Mining & Utilities; and
     6.   Rural, Remote and Mobile Telephony.

     The Company currently sells satellite telephone and related products and
services to the markets listed above. Each subgroup has its own applications and
requires different equipment, service and market approach.
 
PRODUCTS AND SUPPLIERS

     The Company is primarily a global satellite communications firm that
specializes in corporate applications. Specifically, the Company is a provider
of satellite telephone subscriber equipment and services, including Low Earth
Orbit and geostationary Digital Satellite Telephone Systems.

     Low Earth orbit and geostationary Digital Satellite Telephone Systems are
mobile satellite services for voice, fax and data, that span land-mobile, fixed-
site, transportable and maritime applications.  Subscribers on the MSAT System
(i.e., mobile satellite) dial direct, through a communications satellite, using
a variety of satellite terminals.  These mobile terminals are built by leaders
in wireless electronic communications, which include Westinghouse Wireless
Solutions Company, Mitsubishi Electronics of America, Cal Corporation, KVH
Maritime Products, Kyocera and Motorola.  The Company is a distributor for
Westinghouse mobile terminals.

      Pursuant to its agreement with AMSC Subsidiary Corporation ("AMSC"), a
wholly-owned subsidiary of American Mobile Satellite Corporation, the Company
purchases and resells mobile satellite service on a private network basis.  This
telephone service provides traditional voice, fax and data service through
satellite terminals that are similar to cellular phones. Telephone calls made
through the Skysite Satellite Telephone System on these mobile satellite
terminals initiate contact with the outside world through one L-Band (1.5Ghz)
GM/Hughes communications satellite in geo-synchronous orbit 22,300 miles above
the equator.  The satellite is downlinked into the Public Switched Telephone
Network through a Westinghouse-built Communications Ground Segment ("CGS") earth
station located in Reston, Virginia.  Within the satellite coverage area, which
encompasses most of North and Central America, Hawaii, the western Atlantic and
eastern Pacific oceans, the entire Caribbean basin and the northern portion of
Columbia and Venezuela, a subscriber can make or receive direct dial calls
generally to or from anywhere in the world.  This is a dial-up-on-demand system
that charges the subscriber for the time actually used.

     Satellite telephony customers also have the opportunity to subscribe for
advanced services.  These offerings include voice mail, conference circuit
services, and disaster recovery telephone testing and audit services.  Unlike
cellular, a satellite telephone cannot be monitored.  The Company's services
also include full STU 3 encryption, which scrambles voice communication, when
required.  With the special security system unique to the MSAT I satellite, the
telephone cannot be "cloned," which is the number one cause of fraud among
cellular roaming customers.

                                       9
<PAGE>
 
     In addition to dial-up telephone service, the Company also offers a half-
duplex, push-to-talk ("PTT") dispatch system that can be set up on a channeled
basis into talk groups organized along hierarchical, geographical or task-
related lines.  When in this mode, users activating their talk group channel are
put directly in contact with each other, without interfacing with the Public
Switched Telephone or Data Networks.

     As a complement to its other products and services, the Company also offers
pagers through its non-exclusive distribution agreement with CUE paging network,
covering the U.S. and Canada, and the ARDIS two-way wireless data services.

     The Company, pursuant to an agreement with PTT Telecom BV (as represented
by Station 12, the satellite division of PTT Telecom BV), dated September 15,
1997, also offers Inmarsat and other satellite services provided by Station 12,
which services are marketed under the brand name of "Altus."

     The Company also plans to offer, on a non-exclusive basis, Iridium services
throughout the world, and subscriber units pursuant to its agreement for a term
of three years with Iridium U.S., L.P.   Iridium is a network of low-earth orbit
satellites.  The launch of commercial service on the Iridium system is expected
before the end of 1998, but there can be no assurance that this goal will be
achieved.  See "Risk Factors--Dependence on Certain Suppliers."

     The Company has relationships with companies in both the wireless
communications industry and the Company's selected industry market segments as a
non-exclusive distributor of satellite telephone products. Westinghouse Wireless
Solutions is  engaged  in a  strategic  supply/marketing  partnership with the
Company.  The breadth of this relationship includes distribution of the
Westinghouse mobile satellite terminal equipment (SERIES 1000 Satellite
Telephone Systems), joint advertising and marketing that targets dealer and end-
user prospects.  See "--Legal Proceedings" for a description of settlement and
payment with Westinghouse.

PRICING

     As a distributor, the Company purchases products and services on a bulk
basis based on agreed upon prices with its suppliers and then resells those
products and services to its customers.  The Company has a distinct pricing
strategy for each of its major product lines, equipment and telephone services
("airtime").  Retail pricing for satellite terminal equipment is highly
competitive and is characterized by the low gross margins associated with
commodity products.  The Company completes aggressively in this arena, in part,
to establish customer relationships that may result in higher margin airtime
sales.  The Company's pricing schedule for airtime is primarily determined by
the charges established for satellite system operators' and any intermediary
distributor's bulk airtime with whom it deals.

     The Company offers fixed-site, land-mobile, transportable and maritime
telephone equipment ranging in price from approximately $3,000 to $6,000 per
unit.  System price varies depending upon durability, power, battery life and
antenna gain.

     The Company's Satellite Telephone Services is a dial-up-on-demand system
that only charges the subscriber for the time actually used.  For example, if
there is a three-minute call made or received, the subscriber is charged for
only three minutes.  Basic subscriber rates begin at $25.00 per month for voice
telephone service.  Fax and data service is available for a small premium.
These rates include an assigned, toll-free 888 number for each subscriber Mobile
Terminal.

     The Company's STS fixed-site, land-mobile, transportable and maritime
subscribers pay a non-discounted rate of only $1.45 per minute of use.
Industry-specific enhanced service plans provide bulk minutes and full dispatch
channels at a variety of per minute/channel rates.  The Company provides special
"bundled" service packages by industry group to meet the unique needs of the
Company's varied subscriber base.  When a Mobile Terminal makes or receives a
call to or from anywhere in the continental United States, there is no
additional long-distance charge. International long-distance calling is charged
as air time plus international toll from Reston, Virginia.

     The Company's PTT dispatch system is charged out on either a talk group
channel, virtual or dedicated satellite channel basis.

SALES, MARKETING AND DISTRIBUTION

     The Company predominately sells its telephone equipment and airtime
services via a direct-sales force and to a lesser extent via authorized agents.
Prior to August 1998, the direct-sales forces operated from the Company's office
in California.  Since August 1998, the Company has hired sales representatives
who operate from their homes and are located across the United States.  The
Company now has sales representatives in Los Angeles, New York City,

                                       10
<PAGE>
 
Washington, DC, Providence, Charlotte, Fort Lauderdale, Saint Louis, Cincinnati,
Kansas City, San Diego and Portland, Oregon. Each sales representative sells the
Company's full line of products. Product managers assist the sales team in the
configuration of the various services and equipment supported by the Company to
meet the needs of individual customers.

     The Company's marketing program is focused on identifying corporate
prospects in niche markets via direct mail campaigns, attending industry trade
shows and to a limited extent via trade journal advertising. The Company's web
page has been developed to support the sales and marketing effort.  The
Company's marketing program is directed at corporate rather than individual
customers.  The Company has an in-house art and editorial team that develop the
Company's promotional materials.

     The Company's products are warehoused, tested and shipped to customers from
the Company's California office.

CUSTOMERS

     The Company's customers are generally corporations with significant sales
or government entities.  The Company has very few individual customers.  The
Company's largest customer is the Royal Bahamas Police Force who accounted for
22% of sales during 1997.  However, the Company believes 1998 sales to this
customer will drop significantly as approximately half of the Company's revenues
for fiscal 1997 from this customer was from the non-recurring sale of equipment.

COMPETITION

     The wireless communications industry is highly competitive and is
characterized by frequent technological innovation.  The industry includes major
domestic and international companies, many of which have financial, technical,
marketing, sales, distribution and other resources substantially greater than
those of the Company and which provide or plan to provide, a wider range of
services.  The Company's satellite products and services compete with a number
of other communications services including cellular telephone and other wireless
data services, including Qualcomm. In addition, there are a number of planned
satellite systems using new technologies expected to be commercially available
in the next few years, including Globalstar.  Furthermore, the FCC is
considering applications for satellite systems that currently operate in Canada
to provide commercial service in the United States.

     The Company, as non-exclusive service providers for American Mobile
Satellite (AMSC) and Iridium, competes against other service providers of these
products.  For the AMSC products and services, the Company's major competitor is
AMSC's direct sales force.  The Company believes that the list of Iridium
service providers will include, among others, Allied Signal, Bearcom,
CellularOne Paging, GST Telecom, IWL Communications, Pagenet and Motorola
Cellular.

GOVERNMENT REGULATION

     The Company operates as an indirect, unlicensed international
communications carrier in the wireless communications industry and therefore
falls loosely under the regulation of the FCC.  The Company is not the satellite
or equipment licensee, and is not required to maintain manufacturing, service or
operational permits to provide product sales or provision of airtime services.

     However, the Company is critically dependent on its equipment and airtime
suppliers who are, in turn, heavily regulated.  The allocation and use of the
radio frequency spectrum for the provision of communications services are
subject to international and national regulation.  The implementation and
operation of all satellite and wireless systems are dependent upon obtaining
licenses and other approvals.  The national administration of each country
decides how the radio frequencies that the International Telecommunications
Union has allocated to particular communications services should be allocated
and assigned domestically to specific radio systems.  In addition, the provision
of communications services in most countries is subject to regulatory controls
by the national governments of each country.

     The Company is confident that its suppliers will continue to obtain the
approvals and licenses they require to operate globally.  There is, however, no
guarantee that the Company's operation and profitability will not be subject,
directly or indirectly, to restrictive national policies or international
regulation or that the Company will not be subject to increased taxation by
federal, state or local agencies in the future.

PATENTS AND TRADEMARKS

     The Company has five granted patents relating to its ED and UITI
technology.  The Company also owns trademarks on ED in the United States and
France, and on UITI and UITI TV in the United States.  In August 1998, the
Company, pursuant to a settlement agreement, granted Raquel Velasco an option to
purchase the aforementioned intellectual property for $50,000.  See "--Legal
Proceedings."  Skysite's products are not branded, as Skysite is primarily a
reseller and service provider.

EMPLOYEES

     At October 6, 1998, the Company had approximately 29 employees.

ITEM 2.   PROPERTIES

     The Company's headquarters are located in Chevy Chase, Maryland  and
consist of approximately 1,500 square feet.  The annual base rent is
approximately $94,032 and the lease expires December 31, 1998.   The Company
also leases space in Washington D.C., consisting of 1,835 square feet.  The
annual base rent is approximately $58,300, and the lease expires October 31,
1998.  The Company also leases space for Skysite in Burbank, California
consisting of 6,157 square feet.  The annual base rent is approximately $66,000
and the lease expires January 31, 1999.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

     The Company may from time to time make written or oral forward-looking
statements.  Written forward-looking statements may appear in documents filed
with the Commission, in press releases, and in reports to shareholders.  The
Private Securities Reform Act of 1995 contains a safe harbor for forward-looking
statements on which the Company relies in making such disclosures.  Forward-
looking statements can be identified by the use of words such as "believes,"
"anticipates," "plans," "expects," "may," "will," "intends," "estimates" and the
negatives thereof and similar expressions.  The Company's actual results could
differ materially from those anticipated in these forward-looking statements as
a result of certain factors, including those set forth in "Risk Factors" and
elsewhere in this report.

GENERAL

     The Company has incurred net losses in its last three fiscal years.
Moreover, there can be no assurance that the Company or its subsidiaries will
ever generate significant revenues.  Further, there is no guarantee that if the
Company ever achieves a level of profitability, that it can be sustained.

     Pursuant to the Agreement and Plan of Reorganization, dated June 20, 1997,
and the amendment thereto, dated May 28, 1998, U.S. Digital Communications,
Inc., acquired Skysite Communications Corporation.  See "Business--Background."
During 1997, the Company sold 2,882,282 shares of 8% Cumulative Convertible
Preferred Stock, pursuant to Regulation S promulgated by the United States
Securities and Exchange Commission.

RESULTS OF OPERATIONS

     1997 Compared to 1996

     The Company had $486,642 in revenue from sales of satellite equipment and
services in fiscal 1997 compared to no such revenue in fiscal 1996.  This
increase resulted entirely from the Company's acquisition of Skysite.

     Costs of goods sold was $412,767 in fiscal 1997 compared to no cost of
goods sold in fiscal 1996.  These costs were associated with the sales generated
by Skysite.

     Sales and marketing expense for fiscal 1997 was $286,258 compared to no
such expense in fiscal 1996.  These costs were due to the Company's acquisition
of Skysite.

     The Company had no research and development expenses for fiscal 1997, as
compared to $955,570 for fiscal 1996.  This decrease was due to the Company's
decision to terminate the development of the ED device and related products.

     General and administrative expenses, including travel and entertainment
expenses, legal fees and consulting fees, as well as certain other expenses,
increased to $3,582,918 for fiscal 1997, compared to $2,985,039 for fiscal 1996.
This increase of $597,879 was due to the Company's assumption of Skysite's
general and administrative expenses pursuant to the Company's acquisition of
Skysite.

     The Company granted stock options to various employees and other
individuals during fiscal 1997.  In connection with the granting of these
options, the Company recorded a stock option compensation expense in the amount
of $1,349,587.  The amount recorded represents the difference between the
exercise price and the fair market value of the Company's Common Stock, as
determined by reference to the publicly traded value of the stock, as of the
date the options were granted.

     1996 Compared to 1995.

     The Company had no license income in fiscal 1996 compared to $629,688 in
fiscal 1995.  The $629,688 represented the value of the 250,000 shares of
Digital Sciences, Inc. ("Digital") stock received by the Company as an initial
license fee pursuant to an agreement entered into, in 1995, by and between
Digital and the Company, by which the Company licensed its ED technology to
Digital.

     Research and development expenses decreased to $955,570 for fiscal 1996
from $1,010,884 for fiscal 1995, a decrease of $55,314.  This decrease was due
to the decreased activity relating to the production of a prototype of the ED.

                                       17
<PAGE>
 
     General and administrative expenses increased to $2,985,039 for fiscal 1996
from $2,211,605 for fiscal 1995, an increase of $773,434.  This increase was due
to the relocation of the Company into larger office facilities, hiring of
additional employees, increased accounting fees and fees for directors and
officer's insurance, and increased depreciation on the Company's assets.  An
amount of $300,000 was set aside for reimbursement of expenses pursuant to a
severance agreement which includes the Company's former president and a
consultant.  The severance agreement provides that the Company shall reimburse
these individuals for reasonable expenses associated with the Company's business
incurred by them up to an amount equal to approximately $300,000 upon submission
to the Company of valid documentation. The amount of expenses currently claimed
is $255,350.  The Company has recorded a liability of $300,000.  This liability
has been reduced by $96,478, which represents amounts loaned to the former
president by the Company.

 

     An amount of $118,237 has been charged to Operating Expenses for fiscal
1996 in connection with failed efforts to raise additional capital in 1996.

     An amount of $900,000 has been charged to Operating Expenses for fiscal
1996 in connection with the Company's December, 1995 licensing agreement with a
technology company.  In January, 1996, the Company paid an initial royalty
deposit of $450,000.  Pursuant to the licensing agreement, the Company may be
obligated to pay an additional royalty fee of $450,000 in December, 1998.

     The Company granted stock options to various employees and consultants
during fiscal 1996.  In connection with the granting of these options, the
Company recorded compensation and consulting expense, and a related increase to
additional paid-in-capital, in the amount of $2,927,083 during 1996.  The amount
recorded represents the difference between the exercise price and the fair
market value of the Company's Common Stock, as determined by reference to the
publicly traded value of the stock, as of the date the options were granted.

LIQUIDITY AND CAPITAL RESOURCES

     Pursuant to an agreement with a placement agent, Wincap, Ltd. ("Wincap"),
the Company effected two private offerings of 8% Cumulative Convertible Series A
Preferred Stock.  Pursuant to the first offering, the Company sold approximately
2,031,832 shares of Series A Preferred Stock and 1,015,916 warrants to purchase
shares of Common Stock, for a consideration of approximately $3,047,748.
Pursuant to the second offering, the Company sold approximately 2,307,000 shares
of Series A Preferred Stock and 1,153,500 warrants to purchase shares of Common
Stock, for a consideration of approximately $3,460,500, for a total
consideration from both offerings of approximately $6,508,248.  Of this amount,
the Company received approximately $5,749,728, which it intends to use for
working capital.  In addition, Wincap received the right to acquire 2,380,000
shares of the Company's Common Stock, issuable upon registration.

     Pursuant to an agreement with a placement agent, WS Marketing and Financial
Services, Inc., for a private offering of 3,000 shares of Series B Preferred
Stock, as of July 23, 1998 (the date of closing), the Company sold all 3,000
shares for a total consideration of approximately $3,000,000.  Of this amount,
the Company received approximately $2,670,000, which it intends to use for
working capital.  In addition, WS Marketing and Financial Services, Inc.
received 250,000 warrants to purchase Common Stock as part of its placement fee.

     Pursuant to an agreement with a placement agent, WS Marketing and Financial
Services, Inc., for a private offering of 4,000 shares of Series C Preferred
Stock, as of October 6, 1998, the Company sold 3,000 shares for a total
consideration of approximately $3,000,000.  Of this amount, the Company received
approximately $2,670,000, which it intends to use for working capital.    In
addition, WS Marketing and Financial Services, Inc. received 250,000 warrants to
purchase Common Stock as part of its placement fee.


     The Company has generated losses since its inception in May 1990 and cannot
currently generate sufficient revenues and cash flow from operations to meet its
business obligations.

     The Company anticipates it will not need to incur material capital
expenditures in the future.  In prior years, the Company was able to fund its
operations through the issuance of its Common and Preferred Stock in
transactions exempt under the Securities Act of 1933, and through shareholder
loans.  The Company cannot currently generate sufficient revenues and cash flow
from operations to meet its business obligations.  Therefore, future operations
are predicated on raising additional capital in debt or equity markets.

                    NOTES TO UNAUDITED FINANCIAL STATEMENTS
                    AS OF DECEMBER 31, 1995, 1996, AND 1997


1.  OPERATIONS:

U.S. Digital Communications, Inc. ("the Company", a Nevada corporation), is a
provider of satellite and wireless digital communications equipment and services
to corporate and other consumers.  The Company, through a wholly owned
subsidiary, markets satellite telephone products and services to provide
solutions to communications needs of companies with global operations or remote
installations.  Prior to its acquisition of this subsidiary, the Company was a
development stage enterprise founded to develop various internet, modem, video
data and telephone products and devices.  In 1997, the Company discontinued
development of these products.

On November 28, 1995, Global Telephone and Communications, Inc. ("GTCI," a
Nevada corporation), and Visual Information Service Corporation ("Viscorp," an
Illinois corporation) entered into an agreement and plan of reorganization under
which every share of Viscorp stock was exchanged for four shares of GTCI stock.
This resulted in the stockholders of Viscorp obtaining voting control over GTCI.
In conjunction with the transaction, GTCI was renamed Viscorp.  On October 24,
1997, Viscorp was renamed U.S. Digital Communications, Inc.

ACQUISITION OF SKYSITE

On June 20, 1997, the Company entered into an Agreement and Plan of
Reorganization (the "Agreement") with Skysite Communications Corporation
("Skysite").  Under the Agreement, the Company was to issue 750,000 shares of
its common stock to the shareholders of Skysite, as well as options to purchase
an additional 500,000 shares of its common stock at an exercise price of $.40
per share.

The stock of Skysite was transferred to the Company on August 26, 1997.
Subsequent to the acquisition, disputes arose between the Company and the former
President of Skysite related to the value of Skysite at the time of the
acquisition.  As a result of this dispute, the Company withheld its shares.  The
Company has entered into an amended agreement with the shareholders of Skysite,
except for the former President (who was allocated 240,000 shares).  Under the
terms of this amended agreement, the other shareholders' shares and options will
be placed in an escrow account.  The shareholders will have all rights
attributable to these escrowed shares, however, they have agreed that at such
time when they elect to sell these shares, the first $200,000 of related
proceeds will be paid to the Company, and the remaining shares and options will
be released to the shareholders.  The 240,000 shares due to the former President
remain unissued, and the Company does not intend to issue such 

                                      F-6
<PAGE>
 
shares. No shares or options for the other shareholders have been issued or
placed in escrow as of September 1, 1998.

At the time of the acquisition, the Company also entered into an agreement with
the former President of Skysite to issue options to purchase 146,961 shares of
the Company's stock at an exercise price of $.40 per share, over the following
36 months in amounts to be determined by the Company.  The number of options
granted to the former President of Skysite would be adjusted for any material
breach of the Agreement.  In addition, the options to be granted were also based
upon employment services which were to be provided.  No options have been
granted to the former President since the Company believes the former President
did breach the Agreement, and no services were performed.

The Company has recognized the Skysite acquisition as a purchase for accounting
purposes.  The Company has valued the consideration to be given to the
shareholders of Skysite using the 510,000 shares to be placed in escrow and the
related options, less the $200,000 to be received from escrow when these shares
are sold.  This $200,000 has been recognized by the Company as a reduction of
stockholders' equity.  Since the Company does not intend to issue the 240,000
shares to Skysite's former President, the value for these shares ($304,000) has
not been included in the consideration to be given.  If the Company is required
to distribute such shares in the future, the equity and related goodwill
accounts will be increased.  The following is the valuation at August 26, 1997,
the closing date of the acquisition, of consideration to be given for Skysite.

Since the Company has not issued the shares or options due to the other
shareholders, the Company has recorded the value of the consideration to be
given as shares to be issued in stockholders' equity.  At such time when these
shares and options are placed in the escrow account, the Company will recognize
an increase to its common stock and additional paid in capital accounts.  The
purchase price is $1,884,539 in excess of the fair value of the net tangible
assets acquired.  The Company has recognized this as intangible assets.

In accordance with APB Opinion No. 16, the Company allocated the purchase price
based on the fair value of assets acquired and liabilities

RISKS AND OTHER IMPORTANT FACTORS

For the three years ended December 31, 1997, the Company has experienced
significant losses due to its previous development activities and the acquired
Skysite operations.  The success of the Company is dependent on its ability to
generate adequate cash for operations and capital needs.  Its ability to
generate adequate cash for such needs is in part dependent on its success in
increasing sales of Skysite's products and services.  The Company has developed
a plan to increase revenues through sales of products and services, however, due
to market conditions and other factors beyond its control, there can be no
assurance the Company will be able to adequately increase product sales.
Therefore, the Company may have to generate additional cash through the sale of
debt or equity securities.  Although the Company believes it has the ability to
generate additional cash through such sales, such sales may be dilutive and
there can be no assurances that adequate funds will be available or available on
terms that are reasonable or acceptable to the Company.  If the Company is
unable to generate adequate cash there could be a material and adverse effect on
the business and financial condition of the Company.  Therefore, the Company has
developed a plan to implement certain cost control measures to mitigate its
liquidity risk, and is aggressively seeking other companies to acquire that will
increase cash flow and reduce the risk of reliance on Skysite's products and
services.

Future operating results may be affected by a number of other factors including
the timing of new products in the market place, competitive pricing pressures
and economic conditions.  As the market for the Company's product is
characterized by rapidly changing technology, the development and introduction
of competitive products may require a significant investment of financial
resources.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BASIS OF PRESENTATION AND CONSOLIDATION

The consolidated financial statements include the accounts of the Company and
Skysite, after eliminating intercompany balances and transactions.  The amounts
included for Skysite represent all activity from August 26, 1997, the date of
acquisition, to December 31, 1997.

MANAGEMENT'S USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

CASH EQUIVALENTS

The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.  As of December 31,
1997, substantially all funds are held at one financial institution.  The
Company does not believe it is exposed to any significant credit risk on cash
equivalents.

INVENTORIES

Inventories, which consist primarily of finished goods, are stated at the lower
of cost or market.  Cost is determined using the weighted average cost method.
During 1997, the Company's inventory and receivables were pledged as collateral
to a supplier for past due amounts.  The inventory and receivable balance on the
date of the agreement was $433,206.  The supplier subsequently released their
security interest in 1998 (see Note 9).

PROPERTY AND EQUIPMENT

Property and equipment are recorded at historical cost and are being depreciated
over the estimated useful lives of the assets ranging from 3 to 7 years, using
accelerated methods.  For property and equipment under capital lease, the assets
are depreciated over the shorter of the remaining life of the lease or the
useful life of the asset.

INTANGIBLE ASSETS

Intangible assets includes the excess purchase price over net assets received
resulting from the August 26, 1997, acquisition of Skysite.  As of December 31,
1997, the unamortized balance was $1,758,903 (net of 

                                     F-10
<PAGE>
 
accumulated amortization of $125,636). The amortization period being used is
five years.

Prior to the Company's acquisition of Skysite, the Company incurred certain
expenses for patents and trademarks related to the development of various
internet, modem, video data, and telephone products.  Since the Company has
discontinued development of these devices, the Company has written-off the
unamortized balance related to these items as of December 31, 1997.

IMPAIRMENT OF LONG-LIVED ASSETS

The Company complies with the Statement of Financial Accounting Standard
("SFAS") No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of."  SFAS No. 121 requires that long-lived
assets and certain identifiable intangibles held and used by an entity be
reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable.  To determine
recoverability of its long-lived assets, the Company evaluates the probability
that future undiscounted net cash flows will be less than the carrying amounts
of net assets.  Impairment is measured at fair value.

EARNINGS (LOSS) PER COMMON SHARE

Effective January 1, 1997, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 128, "Earnings Per Share" which requires dual
presentation of basic and diluted earnings per share on the face of the income
statement for all periods presented.  Basic earnings per common share are
computed by dividing net loss available to common stockholders by the weighted-
average number of common shares outstanding.  Diluted earnings per common share
are computed by dividing net income by the weighted-average number of shares of
common stock outstanding plus other dilutive securities.

Since the Company had net losses from operations, no potential common shares to
be issued are included in the computation of the diluted per share amount as
they would be anti-dilutive.  Accordingly, the following common stock
equivalents are not included in the weighted-average shares of common stock
outstanding.

FINANCIAL INSTRUMENTS

The carrying amounts of cash and cash equivalents, receivables, and stockholder
loans are a reasonable estimate of their fair value given their short-term
nature.  Investment securities are carried at their fair value.

STOCK-BASED COMPENSATION

During 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS No. 123).  The Company has adopted the disclosure-only
provisions of SFAS No. 123.  Accordingly, when the Company grants stock options
with an exercise price equal to the fair market value of the shares on the date
of grant, no compensation expense is recorded.

RESEARCH AND DEVELOPMENT EXPENSE

The Company expenses research and development costs as they are incurred.

ADVERTISING COSTS

In accordance with the AICPA's Statement of Position 93-7, "Reporting on
Advertising Costs," costs for advertising are expensed as incurred within the
fiscal year.  Such costs are included in sales and marketing expenses in the
accompanying statements of operations.

REVENUE RECOGNITION

The Company recognizes equipment sales revenue upon shipment.  Airtime services
are recognized in the period in which communications services are rendered.
Deferred revenue consists of customer payments received in advance of services
provided under contractual arrangements.

CONCENTRATIONS OF RISK

Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of accounts receivable.  Risk
with respect to accounts receivable is generally diversified among a number of
entities comprising the Company's customer base.  The Company performs ongoing
credit evaluations of its customers' financial condition and maintains
allowances for potential credit losses.  Actual losses and allowances have been
within management's expectations.

                                     F-12
<PAGE>
 
DEFERRED COMPENSATION

The Company records deferred compensation as the difference between the exercise
price of options granted and the fair value of the Company's common stock on the
date of grant.  The amount of deferred compensation recognized in 1996 and 1997
was $6,640,625 and $960,622, respectively.  Deferred compensation is amortized
to expense during the vesting period of the related options.

INCOME TAXES

Deferred income taxes are recognized based on the estimated future tax effects
of temporary differences between the carrying amounts of assets and liabilities
for financial reporting purposes and the amount used for income tax purposes.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amounts expected to be realized.  Income tax expense represents
the current tax provision for the period and the change during the period in
deferred tax asset and liabilities.

RECLASSIFICATIONS

Certain balances from 1995 and 1996 have been reclassified to conform to current
year presentation.

NEW ACCOUNTING PRONOUNCEMENTS

Effective January 1, 1998, the Company will adopt SFAS No. 130, "Reporting
Comprehensive Income," and SFAS 131, "Disclosures about Segments of an
Enterprise and Related Information."  Those statements will require the Company
to change the format of its consolidated financial statements presentation and
disclose certain information related to the different segments of its business.

3.  INVESTMENTS:

In 1997, the Company loaned $50,000 to EDNET, an unrelated company.  Under the
terms of a loan agreement, if EDNET did not repay the loan by June 15, 1997, the
Company would, and did, receive 65,000 shares of EDNET, which were restricted
through June 15, 1998.  The value of these shares on June 15, 1997, was $40,950.
Due to the transaction, the Company has recognized a loss of $9,050, which is
included in loss on investments in the accompanying financial statements.  As of
December 31, 1997, the fair value of these shares was approximately $0.15 per
share.  The Company has classified these shares as available for sale.  The
Company has reflected the reduction in the value of this investment by recording
a $31,200 unrealized loss in stockholders' equity in the accompanying
consolidated balance sheet.

On April 15, 1997, the Company issued 160,000 shares of common stock in full
satisfaction of the $100,000 note payable.  On this date, the outstanding
balance on this note, including accrued interest was $109,500 and the value of
the shares issued was $195,200.  The company recognized a loss on this
transaction of $85,700 which is reflected in loss of repayment of debt within
the accompanying financial statements.

The Company has not made payment on the $300,000 note, which was due March 31,
1998.  Under the terms of the agreement, the lender is entitled to collect a
late payment premium of five percent of any past due amount, which will be
accrued for by the Company in 1998.

On August 24, 1998, the Company entered into a settlement related to an amount
owed to a shareholder of the Company.  The balance owed to the shareholder,
including interest and unreimbursed expenses totaled $1,033,951 as of December
31, 1997.  Under the agreement, the Company will make $250,000 payments on the
following dates:  September 1, 1998, January 5, 1999, and February 28, 1999.
Additionally, the Company will issue 200,000 shares of its restricted common
stock to the shareholder.  The value of the consideration given in exchange for
the extinguishment of this liability is $1,537,500.  This transaction results in
an extraordinary loss of $503,549 in 1998.

Future minimum payments of debt, excluding those amounts payable on demand, are
as follows:

6.  STOCKHOLDERS' EQUITY:

COMMON STOCK

In November 1994, the Company entered into an agreement with a placement agent
for a private offering.  This private offering resulted in the sale of 2,000,000
units at a purchase price of $0.625 per unit for a total consideration of
$1,250,000.  Each unit consisted of one share of common stock, one Class A
warrant and one Class B warrant (no Class A or Class B warrants were exercised
prior to their expiration date).  The placement agent received 200,000 shares of
common stock and 48,000 expense units valued at $155,000 as compensation for its
services and costs.  Each 

                                     F-15
<PAGE>
 
expense unit was composed of one share of common stock, one Class A warrant and
one Class B warrant (no Class A or Class B warrants were exercised prior to
their expiration date).  In addition, attorney and finder's fees totaling
$83,833, paid or to be paid in cash, were incurred and are included as stock
issuance costs.  Of the $83,833, $50,000 was payable at December 31, 1994, to
one consultant.  In addition, the consultant was granted an option, exercisable
until March 8,1998, for the purchase of 80,000 shares of common stock at the
exercise price of $0.625 per share.

During 1995, the Company and the consultant revised the fee structure noted in
the previous paragraph.  In exchange for the cancellation of the $50,000
obligation and the option to purchase 80,000 shares, the consultant received
$25,000 in cash, 40,000 shares of common stock with a deemed value of $25,000
and 120,000 options.  The additional compensation was recorded as general and
administrative expense by the Company.

During 1995, the Company entered into an agreement with an investment advisor to
raise equity financing solely from offshore purchasers and purchasers who may be
deemed "accredited investors" as those terms are generally defined under
Regulation S and Regulation D, respectively, promulgated by the U.S. Securities
and Exchange Commission.  A total of 4,400,000 shares of the Company's stock
were issued at a purchase price of $0.625 per share for a total of $2,750,000.
The placement agent received a finder's fee totaling $330,000 which is included
as stock issuance costs and charged against additional paid-in capital.

Prior to signing the agreement with the investment advisor, the Company had
independently raised $285,000 through the issuance of 212,000 shares at a
purchase price of $1.25 per share and $20,000 through the issuance of 32,000
shares at a purchase price of $0.625 per share in separate transactions.

In addition, an officer of the Company and outside consultants received 600,000
and 66,000 shares, respectively, during 1995 as payment for services rendered,
valued at the price of $0.625 per share.  The value of the shares issued,
$375,000 and $41,250, were charged to research and development, and general and
administrative, respectively.

In February 1996, the Company raised $50,000 through the issuance of 20,000
shares of common stock.  In addition, from March 1 through April 11, 1996, the
Company raised $1,000,000 through the issuance of 500,000 shares of common stock
and $250,000 through the exercise of 400,000 options at a price of $0.625 per
share which were convertible into 400,000 shares.  The options were issued to a
placement agent for raising the $1,000,000 noted in the previous sentence, and
were valued at $2,800,000.  This amount is included as stock issuance costs and
charged to additional paid-in capital in the statement of stockholders' equity.

                                     F-16
<PAGE>
 
In 1997, the Company issued 160,000 common shares to a third party for full
settlement of a note payable (see Note 5).  In addition, the Company reacquired
5,902,200 common shares from a former director for total consideration of $10.

PREFERRED STOCK

SERIES A

In December 1996 and again in August 1997, the Company entered into an agreement
with a placement agent to raise equity financing solely from non-U.S. persons as
defined in Regulation S promulgated by the U.S. Securities and Exchange
Commission through private offerings of the Company's 8 percent cumulative
convertible preferred stock ("Series A"), $0.01 par value per share. The Series
A preferred stock is nonvoting. For each two shares of Series A Preferred Stock,
an investor also received a warrant to purchase the company's Common Stock.

The 1st offering period, according to the December 1996 offering memorandum, was
to expire on June 30, 1997. However, the Company closed that offering in
February of 1997 after selling 2,031,832 shares of Series A Preferred Stock with
1,015,916 warrants for a total consideration of $3,047,748. In August of 1997,
the Company again offered its Series A Preferred Stock and warrants with the
offering period to expire March 31, 1998. The August 1997 memorandum was
subsequently amended and the offering period was extended to July 31, 1998. The
Company raised $3,460,500 through the issuance of 2,307,000 additional shares of
Series A preferred stock and 1,153,500 warrants. The Company raised a total of
$6,508,248 through the issuance of 4,338,832 total shares of Series A preferred
stock in the two offering.

For every two Series A preferred shares purchased, the stockholder received one
warrant (which shall expire three years after the date of execution of the
subscription agreement) to purchase one share of common stock at an exercise
price of $3.00 per share (the "Preferred Stock Warrants"). The Preferred Stock
Warrants shall become exercisable in the same increments and on the same dates
that the conversion rights with respect to the shares to which they are attached
become vested, as described below. As of December 31, 1997, a total of 1,441,116
warrants had been issued. No warrants were exercised in 1997.

The Company has allocated the equity raised between the preferred stock and the
warrants. Based on the valuation of each on the date of issuance, the Company
has allocated approximately $2,868,000 to the preferred stock and $3,640,000 to
the warrants for the entire proceeds received under Series A through closing at
July 31, 1998. As of December 31, 1997, the allocation amounted to $2,725,607
and $1,581,337 for the preferred stock and warrants, respectively.

                                     F-17
<PAGE>
 
Series A preferred stockholders have the right to convert each share into one
share of common stock as follows:  a) 25 percent of the shares 90 days following
the date the shares were issued (the initial conversion date) and b) 25 percent
of the shares at the end of each of the three consecutive 90-day periods
following the initial conversion date.  No conversion of Series A preferred
stock to common stock was made in 1997.

Six months after the date of issuance of the Series A preferred shares, the
Company shall have the option to require the preferred stockholder to convert
each of such shares into one share of common stock.  Upon such conversion, all
of the Preferred Stock Warrants attached to such shares shall become fully
exercisable.

Each Series A preferred stockholder is entitled to receive quarterly dividends
on the last day of March, June, September and December in an amount equal to 8
percent per annum of the stated value of the Preferred stock.  Dividends
totaling $113,985 were paid in 1997.  Additionally, the Company has recognized
dividends payable totaling $135,931.

On the date of issuance of some of the Series A preferred stock, the purchase
price of the shares was less than the quoted market price of the Company's
common stock.  Accordingly, the intrinsic value of this beneficial conversion
feature (approximately $1,529,000) is being accreted to preferred stock over the
conversion rights period.  Accretion of the beneficial conversion feature as of
December 31, 1997, totaled $1,380,000 and is reflected as an increase in the
carrying value of the preferred stock and a dividend charge against retained
earnings.  Subsequent to year-end, additional shares of Series A preferred stock
were issued.  The intrinsic value of the beneficial conversion feature for those
shares was approximately $6,100,000.

Upon any voluntary or involuntary liquidation, dissolution or winding up of the
Company, the holders of the Series A preferred stock will be entitled to be
paid, before any distribution or payment is made in respect of any Common Stock
as to distribution on liquidation, dissolution or winding up, an amount in cash
equal to the aggregate Stated Value ($1.50 per share) of all shares outstanding
plus all accrued but unpaid dividends.

Under the terms of the Placement Agent Agreement related to Series A, the
Placement Agent is entitled to (1) a Placement Fee based on a percentage of
capital raised, (2) options to purchase common stock of the Company and (3) five
percent of the proceeds related to exercise of warrants issued with the Series A
preferred shares.  The total fees earned and the value of the options granted
through the closing at July 31, 1998, amounted to $5,661,320.  In accordance
with the Placement Agent Agreement, on March 6, 1997, the placement agent was
granted 2,800,000 options to purchase common stock of the Company at $.3125 per
share.  On December 12, 1997, these options were canceled and the Company
granted the placement agent 2,800,000 new options, for which the placement agent
could exchange each option for .85 share of the 

                                     F-18
<PAGE>
 
Company's stock upon registration.  The Company calculated the fair value of the
options granted on March 6, 1997, to be $4,256,000.  On December 12, 1997, the
Company valued the new options to be $4,902,800.  The Company has recognized the
value of the new options and the percentage fee earned by the placement agent
and recorded this amount, which totaled $5,410,057 for the year ended December
31, 1997, as stock issuance cost, which is reflected as a reduction of
additional paid-in capital.  In addition, if all warrants issued in the Series A
offering are exercised, the placement agent's 5 percent fee would increase by
approximately $325,000.

SERIES B

In April 1998, the Company created a Series B issue of Preferred Stock, which it
offered in a Regulation D Private Placement.  The Company offered 3,000 shares
of the 10,000,000 authorized shares of Preferred Stock at a purchase price of
$1,000 per share.  Each share had a stated value of $1,000 and no par value.
Series B closed on May 28, 1998.  The Company issued all 3,000 shares for
$3,000,000, resulting in $2,670,000 net cash proceeds to the Company.  (See Note
9 related to the placement agent fee.)  The Series B Preferred Stock will not
pay dividends and is nonvoting stock.

Each share of Series B Preferred Stock shall be convertible into shares of the
Company's common stock based upon a Conversion Formula, as defined in the
Offering agreement.

In conjunction with the offering, 500,000 warrants were issued to the Series B
shareholders proportionate to each investor's number of shares purchased to the
total shares offered.  Each warrant entitles the holder to purchase shares of
the Company's common stock at a price 110 percent of the closing bid price as of
the closing of the Series B offering.  The exercise price is $4.34.  The
exercise price and number of shares to be purchased may be adjusted from time to
time based on computations included in the warrant agreement.  Such warrants are
exercisable for three years after closing of the Series B offering.

The Company has allocated the equity raised between the preferred stock and the
warrants.  Based on the valuation of each on the date of issuance, the Company
will allocate approximately $955,000 to the preferred stock and $2,045,000 to
the warrants.

Each holder of Series B Preferred Stock will have the right to convert their
shares as follows:  a) 50 percent of the shares on the effective date of
registration ("Conversion Date") at the Conversion Price (lesser of (i) 25
percent off the five-day average Closing Bid Price for the Company's common
stock immediately before conversion or (ii) 100 percent of Closing Bid Price for
the Company's common stock on the date of closing, but not less than $.50 per
share of the Company's common stock) and b) 50 percent of the shares on the
45/th/ day after the effective date of registration at the 

                                     F-19
<PAGE>
 
Conversion Price.  The holder shall be entitled to an additional discount
privilege equal to one percent (1%) per month, or fraction of a month, from the
time of closing until the Conversion Date for any conversion thirty (30) days
after the Conversion Date and one-half percent (2%) per month or fraction of a
month for any conversions thereafter ("Additional Discount").  All shares
outstanding on May 1, 2001, will be automatically converted into common stock in
accordance with the Conversion Formula, at the Conversion Price.

The Company will have the right, in its sole discretion, to redeem in whole or
in part any shares of Series B Preferred Stock submitted for conversion.  The
redemption price per share of common stock after conversion of the Series B
Preferred Stock shall be calculated as 133 percent of the face value plus any
accrued Additional Discount.

On the date of issuance of the Series B preferred stock, the conversion price of
certain of the Series B preferred stock was less than the quoted market price of
the Company's common stock.  Accordingly, had the shares been converted as of
the issuance date, the intrinsic value of this beneficial conversion feature
would have been approximately $1,288,000.  The eventual accretion of the
intrinsic value of the beneficial conversion feature will be recorded as an
increase in the carrying value of the preferred stock and a dividend charge to
retained earnings over the conversion rights period.

In the event of any liquidation, dissolution or winding-up of the Company,
either voluntary or involuntary (a "Liquidation"), the holders of shares of the
Series B Preferred Stock then issued and outstanding shall be entitled to be
paid out of the assets of the Company available for distribution to its
shareholders, whether from capital, surplus or earnings, before any payment
shall be made to the holders of shares of the Common Stock or upon any other
series of Preferred Stock of the Company with a liquidation preference
subordinate to the liquidation preference of the Series A Preferred Stock.  The
amount of the pay-out will be an amount per share equal to the Stated Value.

The Series B preferred stock subscription agreements contain a "put" provision
for common stock which allows the Company to raise an additional $3,000,000.
The provision specifies that 75 days after the effective date of the
registration of additional common shares to be used under this provision, the
Company may sell common stock (the "Put Stock") to the Series B subscribers.
The price of the Put Stock is determined by taking the lower of (1) 80 percent
of the lowest closing bid price for the previous 20 trading days prior to
funding or (2) 80 percent of the closing bid price on the day of funding.  The
minimum draw is $250,000 and the maximum draw is $750,000.  If the price of the
Company's common stock for the 20 trading days prior to the funding is less than
$1.25 and the average trading volume is less than $300,000 per day for the
previous 20 trading days, the Series B shareholders have the option not to fund
the 

                                     F-20
<PAGE>
 
requested draw.  These minimums increase as the amount of the funds requested by
the Company increase from $250,000 to $750,000.

On the date of issuance of the Series B Preferred Stock with the put provision,
the conversion price under the put provision was less than the quoted market
price of the Company's common stock.  Accordingly, had the put provision been
exercised at the date of issuance of the Series B Preferred Stock, the intrinsic
value of the beneficial conversion feature would have been approximately
$483,000.  The put provision will be recorded as an offsetting charge to
shareholders' equity.  The stock put rights will be amortized over the period of
the put provision with an offsetting charge to retained earnings.  The accretion
of the intrinsic value of the beneficial conversion feature will be recorded
ratably over the term of the put contract (two years from execution of the
subscription agreement) based on the earliest dates the Company may put its
shares.

SERIES C

In August 1998, the Company created a Series C issue of Preferred Stock.  The
Company offered 4,000 shares of the 10,000,000 authorized shares of Preferred
Stock at a purchase price of $1,000 and no par value.  As of September 1, 1998,
the Company had issued 3,000 out of the 4,000 shares for $3,000,000, resulting
in $2,670,000 net cash proceeds to the Company (see Note 9 for discussion of
placement agent fee).  The Company expects to place the remaining 1,000 shares
in the near term.  The Series C preferred stock will not pay dividends and is
nonvoting stock.

In conjunction with the offering, 660,000 warrants will be issued to the Series
C shareholders proportionate to each investor's number of shares purchased to
the total shares offered.  Each warrant entitles the holder to purchase shares
of the Company's common stock at a price of $4.34.  The exercise price and
number of shares to be purchased may be adjusted from time to time based on
computations included in the warrant agreement.  Such warrants are exercisable
for three years after closing of the Series C offering.

The Company has allocated the equity raised between the preferred stock and the
related warrants.  Based on the valuation of each on the date of issuance, the
Company will allocate $1,802,000 to the preferred stock and $1,198,000 to the
warrants.

Fifty percent of each share of Series C Preferred Stock shall be convertible on
the earlier of the effective date of registration of the Company's common stock
("Conversion Date") or one-hundred and twenty (120) days from the closing of the
Series C Preferred Stock, the remaining fifty percent shall be convertible on
the earlier of the forty-fifth day after the effective date of registration or
one-hundred and sixty-five (165) from the closing of the Series C Preferred
Stock.  The Conversion Price will be either the discounted price (twenty-five
percent off of the five-day closing bid price) or $3.94, whichever is less.
However, in no event shall the 

                                     F-21
<PAGE>
 
conversion price be less than $1.875 per share.  In the event the stock is
trading below $1.875, the floor price will be adjusted to the lowest closing bid
price for the Company's common stock during such five-day period from which the
holder shall be entitled to an additional discount.  The holder shall be
entitled to an additional discount privilege equal to one percent (1%) per
month, or fraction of a month, from the time of closing until the Conversion
Date for any conversion thirty (30) days after the Conversion Date and one-half
percent (2%) per month or fraction of a month for any conversions thereafter
("Additional Discount").  All shares outstanding on June 1, 2001, will be
automatically converted into Common Stock on such date in accordance with the
Conversion Formula and the Conversion Price then in effect.

The Company shall have the right in its sole discretion, to redeem, prior to
receipt of the Notice of Conversion, in whole or in part any shares of Series C
Preferred Stock.  The redemption price per share of common stock after
conversion of the Series C Preferred Stock shall be calculated as 133 percent of
the face value plus any unpaid penalty should the Company not effect the date of
registration 150 days from Closing.  The Company shall not have a redemption
privilege if the common stock is trading above $3.50 per share unless the Holder
agrees in writing to allow the Company to redeem such shares.

On the date of issuance of the Series C preferred stock, the conversion price of
certain of the Series C preferred stock was less than the quoted market price of
the Company's common stock.  Accordingly, had the shares been converted as of
the issuance date, the intrinsic value of this beneficial conversion feature
would have been approximately $263,000.  The eventual accretion of the intrinsic
value of the beneficial conversion feature will be measured at the date of
conversion and will be recorded as an increase in the carrying value of the
preferred stock and a dividend charge to retained earnings over the conversion
rights period.

In the event of any liquidation, dissolution or winding-up of the Company,
either voluntary or involuntary (a "Liquidation"), the holders of shares of the
Series C Preferred Stock then issued and outstanding shall be entitled to be
paid out of the assets of the Company available for distribution to its
shareholders, whether from capital, surplus or earnings, before any payment
shall be made to the holders of shares of the Common Stock or upon any other
series of Preferred Stock of the Company with a liquidation preference
subordinate to the liquidation preferences of the Series A and B Preferred
Stock.  The amount of the pay-out will be an amount per share equal to the
Stated Value.

9.  COMMITMENTS AND CONTINGENCIES:

EMPLOYMENT AGREEMENTS

Through December 31, 1995, the Company had entered into separate employment
agreements with four of its officers.  The agreements for the four officers were
to expire November 11, 1997, and automatically renew for an additional one-year
period unless the Company or the employees notified the other party not less
than 120 days prior to the expiration of the agreement of the Company's or the
employees' intent to let the agreement expire.  One of the officers resigned on
January 8, 1997, but the remaining terms and conditions of his employment
agreement remained in full force as they related to his continuing obligations
(i.e., noncompete agreement) to the Company.  The agreements for two of the
officers were terminated by the Board of Directors effective March 15, 1997.

During 1996, the Company entered into separate employment agreements with three
of its officers and one employee.  All agreements expire in 1998 and do not
automatically renew.  The agreements for two of the officers were terminated
August 6, 1996, and January 27, 1997, respectively.

All of the above agreements included the granting of stock options to purchase
common stock.  (See Note 10.)

PLACEMENT AGENT FEE

SERIES B

Under the terms of the Placement Agent Agreement related to the issuance of
Series B Preferred Stock (Note 6), the Placement Agent was paid fees equal to 11
percent of the funded amount of $3 million or $330,000 for the placement of the
3,000 shares of Series B Preferred Stock, 50,000 shares of common stock of the
Company, valued at approximately $200,000 as of the closing date, for
establishing the Put Equity Line of Credit and warrants to purchase 250,000
shares of common stock at a price and under the conditions of the Series B
Preferred Stock investors' warrants, valued at approximately $815,000 as of the
closing date.  In addition, as the Company, at its sole discretion, utilizes the
Put Equity Line of Credit, the Placement Agent will receive a fee of 8 percent
of the cash actually invested at each funding.  If the entire Line of Credit is
used, the Placement Agent would earn an additional $240,000.

SERIES C

Under the terms of the Placement Agent Agreement related to the issuance of
Series C Preferred Stock (Note 6), the Placement Agent was paid fees equal to 11
percent of the funded amount of $3 million or $330,000 for the placement of 

                                      F-25

the 3,000 shares of Series C Preferred Stock, and warrants to purchase 250,000
shares of common stock at a price and under the conditions of the Series C
Preferred Stock investors' warrants, valued at approximately $690,000 as of
September 1, 1998, (Series C has not closed).

LITIGATION

In December 1994, a former officer and director filed suit against the Company,
claiming damages for breach of fiduciary duty, breach of oral agreement,
interference with contractual relations, conspiracy, restitution, and fraud.  On
April 4, 1995, the Company had filed a counterclaim against the plaintiff for
fraud, breach of fiduciary duty, declaratory relief, recession, intentional and
negligent interference with prospective advantage and money loaned.  On December
17, 1996, the Court entered summary judgment against the plaintiff on all claims
against the Company.  On February 5, 1997, all claims were dismissed and final
judgment was entered.  On February 11, 1997, the plaintiff filed a notice of
appeal.  On February 3, 1998, the Company and the plaintiff agreed to a
settlement in which plaintiff would receive a certain number of the Company's
common shares.  The Company has recognized a liability of $178,500, as of
December 31, 1997, related to the settlement.  The liability is included in due
to former officers and shareholders on the accompanying balance sheet.

The Company filed a lawsuit against three individuals formerly associated with
the Company for misappropriation of trade secrets, conversion and breach of
fiduciary duty.  The defendants filed counterclaims against the Company alleging
intentional interference with economic advantage, intentional interference with
contractual relations and unfair competition arising out of the same set of
occurrences.  On July 26, 1996, the Company filed a motion for a preliminary
injunction.  On December 4, 1996, the District Court granted the Company's
motion and issued a preliminary injunction against the defendants.  The
injunction was conditioned upon the Company's posting a bond in the amount of $1
million.  The Company did not post the bond and the injunction was dissolved.
Prior to December 31, 1997, the case was settled in conjunction with another
related case.  See the following paragraph for a discussion of the settlement.

On December 20, 1996, a lawsuit was filed against the Company by one of the
individuals discussed above and another individual formerly associated with the
Company.  The complaint alleges multiple claims including breach of contract,
fraud, negligent misrepresentation, breach of fiduciary duty, wrongful
termination and conversion, all arising out of the plaintiffs' employment with
the Company.  On March 25, 1997, the Company filed a counterclaim for
misappropriation of trade secrets, conversion, and breach of fiduciary duty.  On
June 25, 1997, the Company and the plaintiffs agreed to a settlement in which
the Company would pay cash and provide options to purchase shares of registered
Company common stock.  Currently, the Company is unable to comply with the
requirement because the Company does not have a registration statement on file
with the SEC.  The court has requested continual updates regarding the Company's
efforts to comply.  The Company has recognized a liability of $698,000 related
to the settlement of this case.  The liability is included in due to former
officers and shareholders in the accompanying balance sheet.

                                      F-26

In June 1996, a former Director and Officer filed a Complaint against the
Company, in which he requested the Court to declare that he could sell 220,000
shares of the Company's common stock standing in his name.  The Company also
filed a complaint against the former officer and director in which it asserted
claims for breach of fiduciary duty, breach of a certain Employment Agreement,
accounting as to a certain Severance Agreement, declaratory relief, fraud, and
conspiracy to defraud.  In the declaratory relief claim, the Company alleged
that former Director and Officer is required, pursuant to a certain Reverse
Stock Split Agreement, to return all of his issued and outstanding shares of the
Company so that new certificates equal to one-half the shares presently standing
in his name can be issued to him, the remaining shares to be retained by the
Company.  In September 1997, the former Director and Officer filed a
counterclaim against the Company asserting claims for partial recission of the
Severance Agreement, breach of the Severance Agreement, recission of a certain
Lock-Up Agreement, or in the alternative, breach of the Lock-Up Agreement, and
tortuous interference with economic advantage.  An unfavorable outcome against
the Company would not require the former officer and director to return his
shares under the Reverse Stock Split Agreement.  Additionally, the Company would
be required to pay a maximum of $300,000 under the Severance Agreement among the
former officer and director, and an individual claiming existence of an
employment and/or consulting arrangement.  Currently, the Company has accrued
$203,522 related to this matter as due to former officer on the accompanying
balance sheet.

In November 1997, the individual claiming the existence of an employment and/or
consulting agreement filed a complaint against the Company claiming recission
for breach of a Severance Agreement, or in the alternative, breach of Severance
Agreement.  The settlement of this case would fall within the Severance
settlement in the above case.

On September 1, 1998, a settlement agreement for all outstanding claims and
obligations was reached between the Company and the former officer/director and
the individual claiming existence of an employment and/or consulting agreement.
Under the terms of the settlement agreement, 350,000 shares of the Company's
common stock, previously transferred by the former officer/director to the
individual claiming existence of an employment and/or consulting agreement can
remain with the individual.  The former officer/director will then return his
remaining shares of the Company's common stock, which will be approximately
1,400,000 shares (after the aforementioned transfer), and the Company will
reissue him 350,000 shares of its common stock.  The settlement also provides
that the individual claiming existence of an employment and/or consulting
agreement has the option to purchase the Company's former ED and UITI
technologies for $50,000.

On June 28, 1998, the Company and CBS Corporation agreed to a settlement for
amounts past due, owed to CBS by Skysite.  Under the settlement, the Company was
required to pay CBS $430,000.  The Company has made payment and CBS has released
all of its prior claims and security interests against the Company.  The Company
has fully recognized this settlement in accounts payable and accrued liabilities
in the accompanying consolidated balance sheet.

                                      F-27

On July 27, 1998, a former employee and consultant of the Company filed a
complaint against the Company for breach of an employment contract related to
his employment termination.  The plaintiff has requested unpaid wages and
severance totaling $100,000, the value of 100,000 stock options, which the
former employee believes he is entitled, punitive damages (to be proven at the
time of trial), and related interest.  Management believes that the plaintiff
was terminated for just cause and fully compensated under his employment
agreement.  Given the early stage of the case, it is not possible to determine
the likelihood of an unfavorable outcome on this matter.  Therefore, the Company
has not included an accrual for any possible loss in the accompanying financial
statements.

On August 14, 1998, the Company received correspondence from the legal counsel
of Intelligent Decision Systems, Inc. (see Note 12), alleging breach of certain
terms of a Technology Licensing Agreement, between Intelligent Decisions Systems
and the Company.  Intelligent Decision Systems is requesting return of the
consideration previously paid as the initial license fee, amounting to $968,750,
plus interest from February 1995.  Management intends to vigorously defend the
case.  Due to the recent delivery of the notice, the likelihood of an
unfavorable outcome cannot be determined at this time; therefore no accrual has
been included in the accompanying financial statements.

SUPPLIER AGREEMENT

Skysite is subject to a "take-or-pay" provision pursuant to an agreement with a
supplier of private network satellite products and services.  Under this
agreement, Skysite has made payments totaling $418,593.  Effective January 1,
1998, the Company executed a new agreement with the Company requiring it to make
future minimum purchases from the supplier as follows (assuming no cancellation
of the agreement under termination provisions described below).

Satisfaction of annual commitments are evaluated quarterly, beginning with a
minimum commitment of $33,000 in the first quarter of 1998 plus increases in
subsequent quarterly commitments of $20,000 each.  Notwithstanding the above
provision, the Company may terminate its agreement with the supplier upon 90

In September 1995, the Company adopted a stock option plan that reserved a total
of 2,400,000 shares of authorized, but unissued shares of common stock (the
"1995 Plan").  Options under the 1995 Plan may be granted to employees and/or
parties who render services to the Company.  The final date on which options
could be granted was September 30, 1996.  All options will expire on June 30,
2001 if not previously exercised.  During 1995, 725,200 options were granted to
employees and officers under the 1995 Plan at an exercise price of $0.625 per
share.  No options under the 1995 Plan have been exercised.

In addition, during September 1995, 440,000 stock options were granted to
parties under various settlement agreements at an exercise price of $0.625 per
share.  These options expire in September 2000.  No options have been exercised.

In January 1996, the Company granted options to purchase 170,000 shares of
common stock to various individuals at an exercise price of $0.625 per share
under the 1995 Plan.  All options expire October 1, 2000.  No options have been
exercised.

In March 1996, the Company granted 400,000 options for services rendered in
connection with fund raising activities to an investment advisor.  These options
were exercised in 1996.

In May 1996 and September 1996, the Company, pursuant to employment agreements,
granted options to purchase 575,000 shares of common stock at an exercise price
of $0.625 per share.  These options were issued to three officers and an
employee of the Company.  Options to purchase 100,000 shares of the common stock
were immediately vested with the balance of the options vesting over a two-year
period.  These options expire at various dates through September 2001.  At the
May 1997 Board meeting, the Company elected to cancel 350,000 of these options
that had not vested as of December 31, 1996.  These employees were incorporated
into the new employee stock option plan effective January 1, 1997.

Effective May 6, 1996, the Company established a nonemployee directors' stock
option plan (the "Director Plan") whereby each person who is elected as a
director and constitutes an eligible participant shall be granted an option to
purchase 25,000 shares of common stock on the effective date of his/her becoming
an eligible participant.  Each person who is subsequently re-elected to a second
and third term will be granted an option to purchase an additional 25,000 and
50,000 shares, respectively.  The exercise price per share for all options
granted under the Director Plan will be equal to the market price of the common
stock as of the date of grant.  The term of each option is for a period of five
years from the date of grant.  During 1996, three directors were elected with
each receiving 25,000 options.  Effective March 15, 1997, the Board of Directors
amended the plan, entitling each outside director to receive 40,000 options
quarterly which will vest on the following dates:  March 15, 1997; June 15,
1997; September 15, 1997; December 15, 1997; and March 15, 1998.  The exercise
price of each option will be the average bid price for the 90 days immediately
preceding the vesting.  The difference between the exercise price and the fair
value of the stock as of the date of issuance represents deferred compensation
which the Company will 

                                      F-32
<PAGE>
 
recognize on the date the options vest. If a director should resign, options
will be awarded according to the above schedule through the closing date of the
quarter in which he/she submits the resignation. The Company reserved 300,000
shares of authorized, but unissued shares of common stock for this plan.

Effective March 14, 1997, the Board of Directors asked that the two employees of
the Company vacate their Employee Agreements and continue to work for the
Company under the new Employee Stock Option Plan.  Under the new plan, any and
all employees' in previous agreements will have their options pro-rated through
December 31, 1996.  All full-time employees of record on January 1, 1997, will
be covered by the new Employee Stock Option Plan.  Every full-time employee on
record will be granted 25,000 options on the first trading day of each calendar
quarter.  Each option is vested as it is granted and the exercise price of each
option will be $.3125.  As a result of implementation of the new plan and the
change in the options to be given, the Company has canceled the unvested options
by reducing deferred compensation and additional paid-in capital, and valued the
new options based upon the current exercise price and market value.

During 1997, the Company granted 1,045,000 options to employees and nonemployee
directors.  These options were issued under various arrangements with different
terms for the exercise price and vesting periods.  No options have been
exercised.

On February 21, 1998, the Board adopted the 1998 stock option plan which went
into effect on January 1, 1998.  The number of shares increased to 6,000,000.
Officers, other key employees, directors, and advisors of the Company who
contribute to the growth of the Company shall be eligible for the Plan.  Both
the option term and price are to be determined at the date of grant.

The Company has elected to follow Accounting Principles Board ("APB") Opinion
No. 25, "Accounting for Stock Issued to Employees," and related interpretations
in accounting for its employee stock options.  Under APB Opinion No. 25, because
the exercise price of the Company's employee stock options is generally equal to
the fair value of the underlying stock at the date of grant, no compensation
expense is recognized.  In October 1995, the Financial Accounting Standards
Board issued Statement of Financial Accounting Standards ("SFAS") No. 123,
"Accounting for Stock-Based Compensation," which established an alternative
method of expense recognition for stock-based compensation awards to employees
based on fair values.  The Company elected not to adopt SFAS No. 123 for expense
recognition purposes.

Pro forma information regarding net income is required by SFAS No. 123 and has
been determined as if the Company had accounted for its employee stock options
under the fair value method of that statement.  The weighted-average fair value
of options granted during the years ended December 31, 1995, 1996, and 1997, was
$0.63, $10.14, and $1.26, respectively.  The fair value for options was
estimated at the date of grant using a Black-Scholes option pricing model with
the following weighted-average assumptions:

</TABLE>

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options that have no vesting restrictions and are fully
transferable.  In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price characteristics, which
are significantly different from those of traded options, and because changes in
the subjective input assumptions can materially affect the fair value estimate,
in management's opinion, the existing models do not necessarily provide a
reliable single measure of the fair value of its employee stock options.

Had compensation cost for these plans been determined consistent with SFAS No.
123, the Company's net loss and loss per share would have been increased to the
following pro forma amounts:

</TABLE>

Because the method prescribed by SFAS No. 123 has not been applied to options
granted prior to January 1, 1995, the resulting pro forma compensation cost may
not be representative of that to be expected in future years.

11.  LICENSE FEE INCOME:

In January 1995, the Company entered into a license agreement with Digital
Sciences, Inc. to license its "ED" technology and services, and received an
initial license fee paid in the form of 250,000 shares of Digital Sciences, Inc.
common stock with a fair value of $629,688.  The Company recognized this stock
receipt as income during 1995 as management believed that all of the
requirements of the Company under the agreement were completed during the year.
In addition, Digital Sciences, Inc. will pay a license fee based on a percentage
of gross revenue derived from the use of the ED technology and services.  The
Company did not receive any such license fees in 1996 and 1997.

                                      F-34
<PAGE>
 
As a result of various mergers and acquisitions, the Company's shares in Digital
Science, Inc. were converted to shares in Intelligent Decision Systems, Inc.
("IDSI").  In November 1996, the Company agreed to transfer all of its shares of
IDSI stock to a stockholder in exchange for the cancellation of a loan of
$500,000 made by such stockholder to the Company in October 1996.  The Company
recognized a loss of $129,688 on this transfer.

12.  LICENSE FEE EXPENSE:

In 1994, as part of an agreement with NTN Communications, Inc. (NTN), the
Company incurred and expensed a license fee of $250,000.  Of this fee, $200,000
was paid in 1994.  The remaining $50,000 has not been paid and is included in
accounts payable and accrued expenses in the accompanying consolidated balance
sheet.  The initial term of the agreement expires December 13, 2001.  Unless
terminated, the agreement will be extended for a period of seven years.  The
Company has a nonexclusive worldwide license to promote, market and develop an
online computer service, which was to be provided by NTN, for use with the
Company's now abandoned product.  The technology of the computer service
provides two-way interactive computerized games that are broadcast to multiple
locations, can be played by multiple participants at each location and allow the
retrieval and processing of data entered by the participants.  The Company is
required to pay usage royalties as defined in the agreement.  The Company has
not used the NTN online computer service and has not paid any royalties to NTN.
The Company has abandoned this product and does not intend to use the NTN
service in the future.

In January 1996, the Company finalized an agreement with a technology company,
for a nonexclusive, nontransferable license to its computer operating system
technology.  The initial term of the agreement expires December 26, 1998.
Unless terminated, in accordance with the terms of the agreement, the agreement
is to be renewable for subsequent three-year periods at the licensee's option.
The Company is required to pay usage royalties as defined in the agreement.  To
date no usage royalties have been paid by the Company.  Under the terms of the
agreement, the Company is required to pay a minimum royalty of $900,000 to the
licensor or its successors.  In January 1996, the Company paid an initial
royalty deposit of $450,000 to the licensor, and recognized this payment as
research and development expense.  The Company also recorded an additional
liability in the amount of $450,000 for the unpaid portion of the minimum
royalty.

13.  SIGNIFICANT CUSTOMERS/SUPPLIERS:

A significant portion of the Company's net revenues is derived from a limited
number of customers.  From August 26, 1997, to December 31, 1997, approximately
11 percent of this Company's total net revenue was derived from the Royal
Bahamas Police Force.

In addition, the Company purchases its supplies from three suppliers --
Westinghouse Electric, AMSC, and Mitsubishi Electronics America.

14.  RELATED-PARTY TRANSACTIONS:

During 1995 and 1996, the Company made advances to stockholders of $57,908 and
$116,478, respectively.  The 1995 amount, which was originally intended to be
recovered, was forgiven during the year in which it was advanced and accounted
for as compensation expense in 1995.

15.  SUBSEQUENT EVENTS:

In April and August 1998, the Company made loans totaling $510,000 to a target
company in a potential acquisition.  On May 6, 1998, the Company signed a letter
of intent to acquire the target company and certain other companies.
Subsequently, the Company and the target companies mutually rescinded their
letter of intent, and have agreed to renegotiate and restructure the proposed
acquisition.

On July 2, 1998, the Company settled two outstanding cases with two former
officers and directors.  Under the terms of the settlement, the plaintiffs would
return to the Company outstanding common shares totaling 872,000 and the Company
will cancel 450,800 of options previously issued to the plaintiffs.  The Company
would then release the restrictions associated with the remaining shares held by
the two parties.  However, the two parties have agreed to specific terms (i.e.
timing) under which the shares can be sold and the options exercised.
Additionally, one of the plaintiffs has released the Company from any further
payments related to a note payable of $105,000 and accrued interest of $12,701
owed by the Company to the plaintiff as of December 31, 1997 (see Note 5).

DECLINATION/RESIGNATION OF BLACKMAN KALLICK BARTELSTEIN, LLP.

     The Company's former independent public accountants, Blackman Kallick
Bartelstein, LLP ("BKB"), declined to stand for re-election as the Company's
auditors for the fiscal year ended December 31, 1997.

     The declination/resignation of BKB was effected by letter dated September
24, 1997.

     BKB's Report to the Company for the fiscal year ended December 31, 1996 was
qualified with respect to the Company's ability to continue as a going concern.
BKB's report stated that the Company's financial statements had been prepared
assuming that it would continue as a going concern; that the Company continues
to be a development stage enterprise and to date has not generated any revenues
from product sales or positive cash flows from operations; that the ultimate
success of the Company is dependent upon its ability to complete the development
of its products and technology and to successfully introduce its products to the
consumer marketplace; and that the Company must also be able to raise
significant additional capital in debt or equity markets for both the
introduction and development of products and also to sustain the day-to-day
operations of the company.  BKB concluded that these factors raised substantial
doubt about the Company's ability to continue as a going concern.

     The decision to change accountants was not recommended or approved by the
Company's Board of Directors or Audit Committee, although the Board understood
that since the Company had moved its operations to California, it was not
feasible to continue to have its books audited by a small, Chicago, Illinois
based accounting firm and therefore understood that BKB would probably
voluntarily resign or decline to stand for re-election as the Company's
auditors.

     During the two most recent fiscal years, namely the fiscal years ended
December 31, 1996, and December 31, 1997, and the subsequent interim periods
preceding the decision of BKB to decline to stand for re-election as the
Company's auditors, there were no disagreements with BKB on any matter of
accounting principles or practices, financial statement disclosure or auditing
scope or procedure.

ENGAGEMENT/RESIGNATION OF ARTHUR ANDERSEN

     On April 1, 1998, the Company  engaged Arthur Andersen LLP as the Company's
principal accountants to audit the Company's and its subsidiaries financial
statements for the fiscal year ended December 31, 1997. On September 30, 1998, 
the Company's auditors, Arthur Andersen LLP, resigned as the Company's 
independent accountants. The change in accountant is a result of Arthur Andersen
LLP's resignation and was not recommended or approved by the Company's Board of 
Directors, nor was such approval required in order to give effect to the 
resignation. The Company has not yet appointed a new independent accountant.

     Arthur Andersen LLP was engaged to perform an audit of the Company's and 
its subsidiary's 1997 consolidated financial statements and had issued an 
unqualified report, dated September 1, 1998, on the consolidated financial 
statements of the Company and its subsidiary as of and for the year ended 
December 31, 1997. That report, however, was not released by the Company, and on
September 30, 1998, Arthur Andersen LLP withdrew the report. Arthur Andersen 
LLP's resignation and withdrawal were not related to the financial statements. 
Further, there were no disagreements between the Company and Arthur Andersen LLP
on any matter of accounting principles or practices, financial statement 
disclosure, or auditing scope or procedure or reportable events during such 
periods or through the interim period ended September 30, 1998 (date of 
resignation).

     Arthur Andersen LLP has advised the Company that at the time of its 
resignation, it was preparing to issue a management letter with comments and 
suggestions for consideration related to the Company's internal controls. This 
letter was to contain a reference to material weaknesses in the Company's 
internal controls over financial reporting for the year ended December 31, 1997.
However, Arthur Andersen LLP had expanded the scope of its audit to take account
of the weaknesses in internal control so as to be able to issue an unqualified 
report and its resignation and withdrawal of the report were unrelated to the 
Company's financial reporting for the year ended December 31, 1997. Management 
of the Company believes that it has begun to address the issues during 1998 with
the employment of qualified personnel in financial reporting positions.

     The Bylaws of the Company require that the Board of Directors be comprised
of not less than three nor more than nine members. There are currently five
members of the Board of Directors and one vacancy. The Company did not hold an
annual meeting of shareholders in 1997. The Company intends to hold its next
annual meeting of shareholders in late 1998 or early 1999.

     As of March 1997, each non-employee Director received an option to purchase
up to 40,000 shares of Common Stock, every quarter, with the options vesting on
the 15th day of the month preceding the following quarter.  The Company
discontinued the grant of such quarterly options following those grants made in
April 1998.  The Company has granted 300,000 options pursuant to the terms of
the 1996 Non-Employee Directors' Stock Option Plan, as amended (the "1996 Stock
Option Plan") and 435,000 options pursuant to the terms of the 1998 Stock
Option, Deferred Stock and Restricted Stock Plan (the  "1998 Stock Option
Plan").  None of the shares underlying any of the Company's stock option plans
have been registered with the Securities and Exchange Commission.  Furthermore,
many  of the option grants were not granted pursuant to a written plan.  For the
potential consequences of such option grants, see "Risk Factors--Risks
Associated With Stock Option Grants."  Non-employee members of the Board of
Directors are entitled to a retainer fee of $6,000 per year, payable monthly,
and $1,000 per meeting attended, as well as reasonable expenses incurred in
attending such meetings.  No family relationships exist between any of the
Directors or executive officers of the Company or Skysite.

SECTION 16(A) COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires the Company's officers, directors and greater than ten
percent shareholders of a registered class of the Company's equity securities to
file reports of beneficial ownership and changes of beneficial ownership with
the Securities and Exchange Commission.

     Based solely upon a review of Forms 3, 4 and 5 delivered to the Company by
its officers, directors and greater than 10% shareholders, it appears that the
following reports were not timely filed:  Mr. Glenndahl (Form 3); Donald
Gilbreath (Form 3); Roger Remillard (Form 3); William Buck (Form 3); Hugh Jencks
(Form 3); Jerome Greenberg (Form 3); Mitchell Melamed (Form 3); Robert Reid
(Form 3); Mr. Wussler (Form 3); and Mr. Siegel (Form 3).

     The following table sets forth certain information with respect to
compensation for fiscal years ended December 31, 1995, 1996 and 1997 paid to the
Company's Chief Executive Officers (the "Named Executive Officers").  No other
executive officers of the Company received compensation in excess of $100,000
during 1997.

________________

(1)  Upon the resignation of Mr. Buck, Mr.  Siegel replaced him as interim
     President and Chief Executive Officer of the Company in January 1997, and
     in March 1997, Mr. Siegel was appointed to such positions until May 1998,
     when Mr. Wussler succeeded him.
(2)  Mr. Buck resigned from his positions as Chief Executive Officer and
     President of the Company on January 8, 1997.

THE STOCK OPTION PLANS

     The Company has adopted three stock option plans, two of which, the 1996
Stock Option Plan and the 1998 Stock Option Plan, were adopted to provide a
means of performance-based compensation in an effort to attract and retain
qualified personnel. The Company can grant no further options pursuant to the
terms of its third stock option plan.

     1996 Stock Option Plan

     Effective May 1996, the Board of Directors adopted the 1996 Stock Option
Plan.  The 1996 Stock Option Plan provides for the grant of stock options to the
non-employee Directors of the Company.  The terms of the 1996 Stock Option Plan
provide that the exercise price of any options granted shall be no less than the
fair market value of the Common Stock at the time of grant. The exercise period
for any options granted under the 1996 Stock Option Plan is five years.

     The 1996 Stock Option Plan authorizes the grant of options to purchase
300,000 shares of Common Stock and as of October 6, 1998, 300,000 shares
underlying the options were available for issue upon the exercise of such
options.  Subject to anti-dilution provisions for a stock split, stock dividend,
combination or exchange of shares, recapitalization or other change in the
capital structure of the Company, corporate separation or division of the
Company, sale by the Company of all or a substantial portion of its assets,
reorganization, rights offering, a partial or complete liquidation, or any other
similar corporate transaction, the Board of Directors may adjust the number of
shares available for grant under the 1996 Stock Option Plan, the number of
shares underlying outstanding options, the exercise price of outstanding options
and any other characteristics the Board of Directors deems necessary or
appropriate.  In the event of a change in control, as defined in the 1996 Stock
Option Plan, any options not currently exercisable will become exercisable
immediately upon the occurrence of an event constituting a change in control.
Unless previously terminated by the Board of Directors, no options may be
granted under the 1996 Stock Option Plan after December 31, 2000.

                                       22
<PAGE>
 
     The exercise price of any option granted under the 1996 Stock Option Plan
is payable in full (i) in cash, (ii) by surrender of shares of the Company's
Common Stock already owned by the option holder having a market value equal to
the aggregate exercise price of all shares to be purchased, (iii) by the
delivery of cash or the extension of credit by a broker-dealer, (iv) by the
delivery of a  note executed by the optionholder, (v) by requesting that the
Company withhold whole shares of Common Stock then issuable upon exercise of any
option, (vi) by certifying ownership of shares to the Board of Directors for
later delivery, or (vii) by any combination of the foregoing.

     The Board of Directors may from time to time revise or amend the 1996 Stock
Option Plan, and may suspend or discontinue it at any time.  However, no such
revision or amendment may impair the rights of any participant under any
outstanding Award without such participant's consent.

     The Company has granted options to purchase 300,000 shares of Common Stock
at a per share exercise price ranging from approximately $0.50 to $10.87 per
share, vesting within three months from the date of grant under the 1996 Stock
Option Plan.

     1998 Stock Option Plan

     Effective January 1998, the Board of Directors adopted the 1998 Stock
Option, Deferred Stock and Restricted Stock Plan (the "1998 Stock Option Plan"),
which provides for the grant of qualified incentive stock options ("ISOs") that
meet the requirements of Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code"), stock options not so qualified ("NQSOs"), deferred stock,
restricted stock, stock appreciation rights and limited stock appreciation
rights awards ("Awards").  The 1998 Stock Option Plan may be administered by a
committee of directors appointed by the Board of Directors or by the Board (the
"Administrator").  Subject to shareholder approval of the 1998 Stock Option
Plan, ISOs may be granted to the officers and key employees of the Company, any
of its subsidiaries or parent corporation.  The exercise price for any option
granted under the 1998 Stock Option Plan may not be less than 100% (or 110% in
the case of ISOs granted to an employee who is deemed to own in excess of 10% of
the outstanding Common Stock) of the fair market value of the shares of Common
Stock at the time the option is granted.

     The 1998 Stock Option Plan authorizes the grant of options to purchase, and
Awards of 6,000,000 shares of the Company's Common Stock, and as of October 6,
1998, 6,000,000 shares underlying the options were available for issue upon the
exercise of such options.  The number of shares reserved for issuance under the
1998 Stock Option Plan is subject to anti-dilution provisions for stock splits,
stock dividends and similar events.  If an option granted under the 1998 Stock
Option Plan expires or terminates, or an Award is forfeited, the shares subject
to any unexercised portion of such option or Award will again become available
for the issuance of further options or awards under the 1998 Stock Option Plan.

     Under the 1998 Stock Option Plan, the Company may make loans available to
stock option plan holders, subject to the Administrator's approval, in
connection with the exercise of stock options granted under the 1998 Stock
Option Plan.  If shares of Common Stock are pledged as collateral for such
indebtedness, such shares may be returned to the Company in satisfaction of such
indebtedness.  If so returned, such shares shall again be available for issuance
in connection with future stock options and Awards under the 1998 Stock Option
Plan.

     Unless the 1998 Stock Option Plan is previously terminated by the Board of
Directors, no options or Awards may be granted under the Stock Option Plan ten
years after the effective date of the 1998 Stock Option Plan.

     Options granted under the 1998 Stock Option Plan will become exercisable
according to the terms of the grant made by the Administrator.  Awards will be
subject to the terms and restrictions of the award made by the Administrator.
The Administrator has discretionary authority to select participants from among
eligible persons and to determine at the time an option or Award is granted and
in the case of options, whether it is intended to be an ISO or a NQSO, and when
and in what increments shares covered by the option may be purchased.

     Under current law, ISOs may not be granted to any individual who is not
also an officer or employee of the Company, any subsidiary or parent
corporation.

     The exercise price of any option granted under the 1998 Stock Option Plan
is payable in full (i) in cash, (ii) by surrender of shares of the Company's
Common Stock already owned by the option holder having a market value equal to
the aggregate exercise price of all shares to be purchased including, in the
case of the exercise of NQSOs, restricted stock subject to an Award under the
1998 Stock Option Plan, (iii) by cancellation of indebtedness owed by the
Company to the optionholder, (iv) by a full recourse promissory note executed by
the optionholder, (v) by requesting that the Company withhold whole shares of
Common Stock then issuable upon exercise of any option,

                                       23
<PAGE>
 
(vi) by arrangement with a broker which is acceptable to the Administrator, or
(vii) by any combination of the foregoing. The terms of any promissory note may
be changed from time to time by the Board of Directors to comply with applicable
Internal Revenue Service or Commission regulations or other relevant
pronouncements.

     The Board of Directors may from time to time revise or amend the 1998 Stock
Option Plan, and may suspend or discontinue it at any time.  However, no such
revision or amendment may impair the rights of any participant under any
outstanding Award without such participant's consent or may, without shareholder
approval, increase the number of shares subject to the 1998 Stock Option Plan,
materially modify the class of participants eligible to receive options or
Awards under the 1998 Stock Option Plan, or extend the maximum option term under
the 1998 Stock Option Plan.

     The Company has granted options to purchase 435,000 shares of Common Stock
at a per share exercise price ranging from $0.81 to $4.88, vesting from time to
time from the date of grant under the 1998 Stock Option Plan.

     In 1995, the Company adopted a stock option plan which permitted the grant
of options to purchase up to 2,400,000 shares of the Company's common stock
pursuant to Rule 701 of the Securities Act (the "1995 Stock Option Plan").  Rule
701 exempts the sale of securities pursuant to the exercise of stock options for
those companies that are not required to make reports pursuant to Section 13 or
15(d) of the Exchange Act, if certain other conditions and restrictions are
satisfied.  Because the Company is required to file reports pursuant to Section
13 of the Exchange Act, the Company can no longer grant options pursuant to this
Plan.  The Company has granted  options to purchase 1,910,200 shares pursuant to
the 1995 Stock Option Plan, of which, 520,000 shares have been issued and
1,390,200 are available for issue upon the exercise of such options. All grants 
made pursuant to the 1995 Stock Option Plan were made at a per share exercise 
price of approximately $0.63.

     The following tables set forth option grants and exercises for the named
executive officers for the year ended December 31, 1997.

(1)  To the best of the Company's knowledge, Mr. Buck can be reached at 11 Bis
     du Dopropol, 75017 Paris, France. The 350,000 shares Mr. Buck is believed
     to beneficially own is based upon a settlement agreement with the Company
     dated September 1, 1998. Any subsequent acquisitions or dispositions by Mr.
     Buck of the Company's Common Stock are unknown. Mr. Buck is no longer
     affiliated with the Company.
(2)  To the Company's knowledge, except as set forth in the footnotes to this
     table and subject to applicable community property laws, each person named
     in the table has or will have sole voting and investment power with respect
     to the shares of Common Stock set forth opposite such person's name. Each
     of such persons may be reached through the Company at 2 Wisconsin Circle,
     Chevy Chase, Maryland 20815.
(3)  For each of such persons, represents currently vested but unexercised
     options to purchase Common Stock.
(4)  The percentage of beneficial ownership is calculated using 15,526,800
     shares of Common Stock which were outstanding on October 6, 1998.
     Beneficial ownership is determined in accordance with the rules of the
     Securities and Exchange Commission and generally includes voting or
     investment power with respect to the securities.  In computing the number
     of shares beneficially owned by a person and the percentage of ownership of
     that person, shares of Common Stock subject to options held by that person
     that are currently exercisable within 60 days of October 6, 1998 are deemed
     outstanding.  Such shares, however, are not deemed outstanding for purposes
     of computing percentage ownership of any other person.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

          William Buck, the Company's former President and Chief Executive
Officer and Director resigned on January 8, 1997.  The resignation related to
his position as an officer and Director of the Company and any of the Company's
wholly-owned subsidiaries.  The Board of Directors approved a severance
agreement which included the former President and an individual claiming to have
incurred expenses on behalf of the Company as a consultant.  The severance
agreement provided that the Company would reimburse the former President and the
alleged consultant for reasonable expenses associated with the Company's
business incurred by them up to an amount approximately equal to $300,000 upon
submission to the Company of valid documentation approved by the Company.

          In June 1997, the Company filed a complaint against Mr. Buck in the
United States District Court for the Northern District of Illinois, Eastern
Division asserting claims for breach of fiduciary duty, breach of employment
agreement, accounting as to his severance agreement, fraud and conspiracy to
defraud.  The Company is also requesting declaratory relief seeking the return
of Mr. Buck's certificates for the Company's Common Stock so that new
certificates equal to one-half of those surrendered would be reissued to Mr.
Buck in accordance with the terms of a reverse stock split agreement.  In
September 1997, Mr. Buck filed a counterclaim against the Company alleging
breach of the severance agreement, breach of a lock-up agreement and tortious
interference with economic advantage. See "Business--Legal Proceedings" for a
more detailed description of the lawsuit.

          On June 23, 1997, Mr. Buck filed a lawsuit in the United States
District Court for the Northern District of Illinois Eastern Division against
the Company praying for a declaratory judgment that certain shares of the
Company's Common Stock beneficially owned by Mr. Buck could be sold pursuant to
Rule 144 of the Securities Act.  See "Business--Legal Proceedings" for a more
detailed description of the lawsuit.

          On September 1, 1998, the Company entered into a Settlement Agreement
and Release with Mr. Buck resolving all disputes, claims and differences between
the parties.  The Settlement Agreement and Release provided that Mr. Buck would
be entitled to retain 350,000 shares of the Company's Common Stock, which shares
could be sold by him in accordance with a tradeability schedule limiting the
number of shares that could be sold by him during any month for a period of two
years.

          On June 20, 1997, Jerome Greenberg agreed to contribute to the
Company's treasury 5,902,200 shares of Common Stock that he beneficially owned
in exchange for $10 and an agreement by the Company to use 6% of the funds
raised from the sale of its Series A Preferred Stock to repay outstanding notes
payable owed to Mr. Greenberg.  As a result of this contribution, Mr. Greenberg
retained 655,800 shares (plus options to purchase an aggregate of 100,000 shares
of Common Stock).   The Company entered into a settlement agreement with Mr.
Greenberg on August 24, 1998 whereby the Company agreed to grant 200,000 shares
of Common Stock to Mr. Greenberg and to pay him an aggregate of $750,000 in
three equal installments on September 1, 1998 and January 5 and February 28,
1999 as payment in full for the Company's outstanding obligation.

          In December 1997, Donald Gilbreath, a former Vice President of the
Company, filed a complaint in the United States District Court for the District
of Colorado alleging that the Company wrongfully interfered with the sale of
certain shares of the Company's Common Stock owned by Mr. Gilbreath and refused
to permit Mr. Gilbreath to exercise certain vested options to purchase the
Company's Common Stock.  In July 1998, Mr. Gilbreath entered into a settlement
agreement which permitted him to keep one-half of his shares of the Company's
Common Stock with all restrictive legends removed.  Mr. Gilbreath is subject to
a restrictive tradeability schedule as to the disposition of said shares.  See
"Business--Legal Proceedings" for a more detailed description of the lawsuit.

          In June 1997, Roger Remillard, a former Director of the Company, and
his wife filed a complaint in the United States District Court for the District
of Colorado alleging that the Company wrongfully refused to remove legends from
certain of the Remillards' shares of the Company's Common Stock, that the
Company refused to permit the Remillards to exercise certain vested stock
options, that the Company wrongfully interfered with a private contract of Mr.
Remillard with a third party and that the Company failed to pay certain sums to
Mr. Remillard under a demand promissory note.  In July 1998, the Company and the
Remillards entered into a settlement agreement in which the Remillards were
allowed to retain a majority of their 1,192,000 shares of the Company's Common
Stock with all restrictive legends removed.  The Remillards are subject to a
restrictive tradeability schedule as to the disposition of said shares.
Pursuant to the settlement agreement, the Remillards were permitted to retain
200,000 stock options, which must be exercised before January 1, 1999.  See
"Business--Legal Proceedings" for a more detailed description of the lawsuit.

          In March 1997, the Board of Directors agreed to pay Robert Wussler a
consulting fee of $8,000 per month. This consulting fee arrangement was
discontinued when Mr. Wussler was appointed President and Chief Executive
Officer of the Company in July 1998.

stock of SKYSITE and the Shareholders of SKYSITE desire to exchange all of 
their shares of SKYSITE capital stock for shares of VISCORP authorized but 
unissued shares of stock as hereinafter provided.

     B.  It is the intention of the parties hereto that:  (i) VISCORP shall 
acquire all of the issued and outstanding capital stock of SKYSITE in exchange 
solely for the number of shares of VISCORP authorized but unissued shares of 
Common Stock, par value $.01 ("Common Stock"), set forth below (the "Exchange");
(ii) the Exchange shall qualify as a tax free reorganization under Section 
368(a)(1)(B) of the Internal Revenue Code of 1986, as amended, and related 
sections thereunder; and (iii) the Exchange shall qualify as a transaction in 
securities exempt from registration or qualification under the Securities Act 
of 1933, as amended, and under the applicable securities laws of each state 
or jurisdiction where the Shareholders reside.

     C. The board of directors of VISCORP deem it to be in the best interest of 
VISCORP and its shareholders to acquire all of the issued and outstanding
capital stock of SKYSITE.

     D. The board of directors of SKYSITE deem it to be in the best interest of 
its shareholders to exchange all of the capital stock of SKYSITE for shares of

     NOW, THEREFORE, in consideration of the mutual covenants, agreements, 
representations and warranties contained in this Agreement, the parties hereto 
agree as follows:

                        AMENDMENT TO AGREEMENT AND PLAN
                               OF REORGANIZATION
                                (May 28, 1998)

     The parties to this Agreement are U.S. Digital Communications, Inc.
(formerly VisCorp), a Nevada corporation ("USDI"), and each of the following
former shareholders of Skysite Communications Corporation ("Skysite"), a
Delaware corporation: Intercontinental Technologies Group, Inc. ("ITG"), Cochran
Ranch and Tennis Club, Inc., by Michael Savage, its president ("Cochran"), Sinai
Administrative Trust, in favor of Ruben Kitay, its trustee ("Sinai"), George
Straayer, Carol Anderson and Howard Garber. Collectively, this group will be
identified as the "Selling Shareholders".

     This Amendment Agreement is intended to modify the Agreement and Plan of 
Reorganization ("Merger Agreement"), executed by all of the above Selling 
Shareholders on or before June 6, 1997, and between USDI, Skysite, the Selling 
Shareholders and Tom Soumas, also a former shareholder of Skysite, but not a 
party to this Amendment Agreement.

                                   Recitals

     Whereas, disputes have arisen between USDI and Soumas, and these disputes 
have been focused on the value of Skysite at the time of its transfer to USDI, 
causing USDI to dispute the value of the transfers to the Selling Shareholders, 
arguably as participants in the valuation (or lessening of valuation) of 
Skysite, and

     Whereas, the parties to this Amendment Agreement desire to resolve their 
outstanding differences and deal only with the misrepresentations and 
inaccuracies attributable to Soumas,

NOW, THEREFORE, in consideration of the mutual covenants, agreements,
representations, and warranties contained in this Amendment Agreement, the
parties hereto agree as follows:

Section 1.0  Modified Consideration

        1.1 The consideration originally set forth in the June 6, 1997, Merger
Agreement as to the Selling Shareholders (510,000 shares of common stock, plus
500,000 options exercisable at $0.40 per share) will remain as the consideration
to be delivered to the Selling Shareholders, subject to 1.2 below.

        1.2 The Selling Shareholders will pay to USDI, as compensation for the
errors, misrepresentations and/or inaccuracies of Soumas, the sum of $200,000,
said sum to be deducted from any sales of the common stock being delivered to
the Selling Shareholders under (S) 1.1.

        1.3 An escrow account at the Smith Barney (New York) brokerage firm will
be
<PAGE>
 
established for purposes of executing the terms of this Section 1.0. All of the 
shares of common stock and all of the option rights will be deposited by USDI 
into that escrow, along with instructions to pay to USDI the first $200,000 
realized by any sales of the stock. Furthermore, USDI will be paid the first 
$0.40 on the exercise of any of the options, pursuant to the terms and 
conditions set forth within the options themselves. Once the initial $200,000 
has been tendered to USDI, the remainder of the common shares still contained in
the account will be free of further USDI-imposed restrictions under this Section
1.3 and may be distributed to the Selling Shareholders according to any 
agreement satisfactory to them (subject to any restrictive legends as provided 
for in Section 4.1 below) and USDI will have no further interest in these 
shares. The options, if unexercised, may also be distributed to the Selling 
Shareholders.

Section 2.0  Assignment of Claims

        2.1  In consideration for the payment of $200,000 to USDI by the Selling
Shareholders, USDI hereby assigns to the Selling Shareholders all claims USDI 
has arising out of the Merger Agreement and the transactions contemplated 
therein. Nevertheless, USDI will retain any claims it has against Soumas (i) for
the use of USDI's trade secrets and other proprietary information for the 
conduct of a competing business, and (ii) the conversion by Soumas of certain 
property of USDI. Should the Selling Shareholders institute an action against 
Soumas to recover any portion of the $200,000 paid to USDI, which is being paid 
against a total claim by USDI of $480,000 in losses caused by Soumas, then USDI 
will be entitled to 33.3% of all funds actually recovered from Soumas by the 
Selling Shareholders. The recovery will be net of actual costs for attorneys' 
fees, costs advanced, expert or lay witnesses, and other similar and reasonable 
charges arising in litigation or arbitration.

        2.2  Notwithstanding (P) 2.1 above, USDI will retain the right to raise 
as a defense, counterclaim, set off or recoupment, to any claims or action 
brought by Soumas against USDI, all damages caused by the misrepresentations 
made by Skysite and Soumas in the Merger Agreement and the related transactions,
including all negotiations related thereto. The parties will agree prior to any 
settlement with Soumas pursuant to this (P) 2.2 as to the allocation, by either 
of the parties, of the "offsets" or the "recovered" amounts, since these amounts
may have an impact on the other party's litigation efforts against Soumas.

Section 3.0  Assistance of USDI/ITG Personnel

        3.1  USDI and ITG agree to assist each other in the anticipated 
litigation against Soumas.

        3.2  The Selling Shareholders agree to assist USDI in any litigation 
resulting from the Merger Agreement or this Amendment Agreement in any 
subsequent litigation or arbitration between Soumas and USDI.

        3.3  Neither USDI nor ITG can commit to provide the assistance of any 
individuals who are no longer in its employ.
<PAGE>
 
     3.4  Both ITG and USDI shall provide reasonable notice prior to scheduling 
any matter requiring the use of USDI or ITG personnel. In addition, USDI and/or 
ITG shall be reimbursed for any out of pocket expenditures, travel expenses, and
attorneys fees incurred by the non-litigating party in responding to requests of
the litigating party. The reimbursement of these items will be made out of the 
first proceeds of the respective litigation.

Section 4.0  Legal Opinion Concerning the Tradeability of Shares

     4.1  Any legal opinion obtained by the Selling Shareholders regarding the 
tradeability of shares must be obtained from counsel approved by USDI in its 
reasonable discretion. In addition, any such counsel shall have sufficient 
experience in security matters to render an opinion (at least 10 years 
experience) and shall have malpractice insurance with with limits of no less 
than three million dollars ($3,000,000). All shares of stock issued to Selling 
Shareholders shall contain all appropriate restrictions.

     4.2  USDI will aid in the documentation of any factual representations 
necessary to provide the counsel providing the opinion with assurances as to the
events or dates and times in question, the number of issued and outstanding 
securities, the identification of officers, directors and/or affiliates and any 
other information reasonably requested by the opining counsel. Notwithstanding 
any other provisions of this Amendment, the Selling Shareholders agree not to

     The undersigned President and Secretary of this Corporation hereby certify 
that Board of Directors of this Corporation, pursuant to the authority expressly
vested in it has adopted the following resolutions creating a Series B issue of

     RESOLVED, that three thousand (3,000) of the ten million authorized shares

          C.   Liquidation Preference.
               ----------------------

               1.   In the event of any liquidation, dissolution or winding-up
               of the Corporation, either voluntary or involuntary (a
               "Liquidation"), the holders of shares of the Series B Preferred
               Stock then issued and outstanding shall be entitled to be paid
               out of the assets of the Corporation available for distribution
               to its shareholders, whether from capital, surplus or earnings,
               before any payment shall be made to the holders of shares of the
               Common Stock or upon any other series of Preferred Stock of the
               Corporation with a liquidation preference subordinate to the
               liquidation preference of the Series A Preferred Stock, an amount
               per share equal to the sum of (i) the Stated Value and (ii) an
               amount equal to zero percent (0.00%) of the Stated Value
               multiplied by the fraction N/365, where N equals the number of
               days elapsed since full payment for the shares of Series B
               Preferred Stock was deposited with the escrow agent for the
               offering of the Series B Preferred Stock. If, upon any
               Liquidation of the Corporation, the assets of the Corporation
               available for distribution to its shareholders shall be
               insufficient to pay the holders of shares of the Series B
               Preferred Stock and the holders of any other series of Preferred
               Stock with a liquidation preference equal to the liquidation
               preference of the Series B Preferred Stock the full amounts to
               which they shall respectively be entitled, the holders of shares
               of the Series B Preferred Stock and the holders of any other
               series of Preferred Stock with liquidation preference equal to
               the liquidation preference of the Series B Preferred Stock shall
               receive all of the assets of the Corporation available for
               distribution and each such holder of shares of the Series B
               Preferred Stock and the holders of any other series of Preferred
               Stock with a liquidation preference equal to the liquidation
               preference of the Series B Preferred Stock shall share ratably in
               any distribution in accordance with the amounts due such
               shareholders. After payment shall have been made to the holders
               of shares of the Series B Preferred Stock of the full amount to
               which they shall be entitled, as aforesaid, the holders of shares
               of the Series B Preferred Stock shall be entitled to no further
               distributions thereon and the holders of shares of the Common
               Stock and of shares of any other series of stock of the
               Corporation shall be entitled to share, according to their
               respective rights and preferences, in all remaining assets of the
               Corporation available for distribution to its shareholders.

               2.   A merger or consolidation of the Corporation with or into
               any other corporation, or a sale, lease, exchange, or transfer of
               all or any part of the assets of the Corporation which shall not
               in fact result in the liquidation (in whole or in part) of the
               Corporation and the distribution of its assets to its
               shareholders shall not be deemed to be a voluntary or involuntary
               liquidation (in whole or in part), dissolution, or winding-up of
               the Corporation.

          D.   Conversion of Series B Preferred Stock.
               --------------------------------------

               The holders of Series B Preferred Stock shall have the following 
conversion rights:

               1.   Right to Convert.  Fifty percent (50%) of each share of
                    ----------------
               Series B Preferred Stock shall be convertible, on the effective
               date of registration and at the Conversion Prices set forth
               below, into fully paid and nonassessable shares of Common Stock
               and the remaining fifty percent (50%) of each share of Series B
               Preferred Stock shall be convertible on the forty-fifty (45th)
               day after the effective date of registration at the Conversion
               Prices set forth below (sometimes referred to herein as
               "Conversion Shares").

               2.   Mechanics of Conversion.  Each holder of Series B Preferred
                    -----------------------
               Stock who desires to convert the same into shares of Common Stock
               shall provide notice ("Conversion Notice") via telecopy
               (facsimile) to the Corporation. The original Conversion Notice
               and the certificate or certificates representing the Series B
               Preferred Stock for which conversion is elected, shall be
               delivered to the Corporation by international courier, duly
               endorsed. The date upon which a Conversion Notice is received by
               the Corporation shall be a "Notice Date."

     Upon receipt by the Corporation of a facsimile copy of a Conversion Notice,
the Corporation shall immediately send to the holder, via telecopy (facsimile), 
a confirmation of receipt of the Conversion notice which shall specify that the 
Conversion Notice has been received and the name and telephone number of a 
contact person at the Corporation whom the holder should contact regarding 
information related to the conversion. The Corporation shall use all reasonable 
efforts to issue and deliver within three (3) business days after the Notice 
Date, to such holder of Series B Preferred Stock at the address of the holder on
the stock books of the Corporation, a certificate or certificates for the number
of shares of Common Stock to which the holder shall be entitled as aforesaid; 
provided that the original shares of Series B Preferred Stock to be converted 
are received by the transfer agent or the Corporation within three (3)

                                      -3-
<PAGE>
 
Business days after the Notice Date and the person or persons entitled to 
receive the shares of Common Stock issuable upon such conversion shall be 
treated for all purposes as the record holder or holders of such shares of 
Common Stock on such date. If the original certificate(s) representing the 
shares of Series B Preferred Stock to be converted are not received by the 
transfer agent or the Corporation within three (3) business days after the
Notice Date, the Conversion Notice shall become null and void.

          3. Lost or Stolen Certificates. Upon receipt by the Corporation of 
             --------------------------- 
          evidence of the loss, destruction, theft or mutilation of any Series B
          Preferred Stock certificates (the "Certificates") and (in the case of
          loss, theft or destruction) of indemnity or security reasonably
          satisfactory to the Corporation, and upon surrender and cancellation
          of the Certificates, if mutilated, the Corporation shall execute and
          deliver new Series B Preferred Stock Certificates of like tenor and
          date. However, the Corporation shall not be obligated to re-issue such
          lost or stolen Series B Preferred Stock Certificates if the holder
          thereof contemporaneously requests the Corporation to convert such
          Series B Preferred Stock into Common Stock, in which event the
          Corporation shall be entitled to rely on an affidavit of loss,
          destruction or theft of the Series B Preferred Stock Certificate or,
          in the case of mutilation, tender of the mutilated certificate, and
          shall issue the Conversion Shares.

          4. Conversion Dates. The shares of Series B Preferred Stock shall
             ----------------
          become convertible into shares of Common Stock at any time commencing
                                  ------
          (i) the effective date of a registration statement covering the
          Conversion Shares and (ii) forty-five (45) days after the effective
          date of registration of the shares to be converted (referred to as a
          "Conversion Date").

          5. Conversion Formula/ Conversion Price. Each share of Series B
             ------------------------------------
          Preferred Stock shall be convertible into the number of shares of
          Common Stock in accordance with the following formula (the "Conversion
          Formula"):


          [(.00) x (N/365) x (1,000)] + 1.000
          -----------------------------------=
                  Conversion Price

where,

       N=  the number of days between (i) the date that, in connection with the 
         consummation of the initial purchase by holder of shares

                                      -4-
<PAGE>
 
               of Series B Preferred Stock from the Corporation, the escrow
               agent first had in its possession funds representing full payment
               for the shares of Series B Preferred Stock being converted, and
               (ii) the Notice Date.

          Conversion
          Price =        Discount Price or the Ceiling Price, whichever is less,
                         but in no event shall the Conversion Price be less than
                         the Floor Price.

          Discount
          Price =        25% of five (5)-day average Closing Bid Price for the
                         Corporation's Common Stock immediately before
                         Conversion Date.

          Ceiling
          Price =        100% of Closing Bid Price for the Corporation's Common 
                         Stock the date of Closing.

          Floor Price =  $.50 per share of the Corporation's Common Stock with
                         the agreement to adjust the floor should the
                         Corporation's Common Stock trade less than $.50 per
                         share for five (5) consecutive days prior to the
                         conversion dates herein. The adjusted floor shall then
                         be the lowest Closing Bid Price for the Corporation's
                         Common Stock during such five (5)-day period.

     For purposes hereof, the term "Closing Bid Price" shall mean the closing 
bid price for the Corporation's Common Stock on the NASD Electronic Bulletin 
Board, or if no longer traded thereon, the closing bid price on the principal 
national securities exchange on which the Common Stock is so traded. The holder 
shall be entitled to an additional discount privilege equal to one percent (1%) 
per month, or fraction of a month, from the time of closing until the Conversion
Date for any conversions thirty (30) days after the Conversion Date and one-half
percent (1/2%) per month or fraction of a month for any conversions thereafter 
("Additional Discount").

               6.   Automatic Conversion.  Each share of Series B Preferred
                    --------------------
               Stock outstanding on May 1, 2001 automatically shall be converted
               into Common Stock on such date in accordance with the Conversion
               Formula and the Conversion Price then in effect, and May 1, 2001
               shall be deemed to be the Notice Date with respect to such
               conversion.

                                    - 5 -                 
<PAGE>
 
     7.  No Fractional Shares. If any conversion of the Series B Preferred
         --------------------
         Stock would create a fractional share of Common Stock or a right to
         acquire a fractional share of Common Stock, such fractional share shall
         be disregarded and the number of shares of Common Stock issuable upon
         conversion, if the aggregate, shall be the next higher number of
         shares.

     8.  Reservation of Stock Issuable Upon Conversion. The Corporation shall at
         ---------------------------------------------
         all times reserve and keep available out of its authorized but unissued
         shares of Common Stock, solely for the purpose of effecting the
         conversion of the shares of the Series B Preferred Stock, such number
         of its shares of Common Stock as shall from time to time be sufficient
         to effect the conversion of all then outstanding shares of the Series B
         Preferred Stock; and if at any time the number of authorized but
         unissued shares of Common Stock shall not be sufficient to effect the
         conversion of all then outstanding shares of the Series B Preferred
         Stock, the Corporation will take such corporate action as may be
         necessary to increase its authorized but unissued shares of Common
         Stock to such number of shares as shall be sufficient for such purpose.
     
     9.  Adjustment to Conversion Price.
         ------------------------------

           (a) If, prior to the conversion of all shares of Series B Preferred
           Stock, the number of outstanding shares of Common Stock is increased
           by a stock split, stock dividend, or other similar event, the
           Conversion Price shall be proportionately reduced, or if the number
           of outstanding shares of Common Stock is decreased by a combination
           or reclassification of shares, or other similar event, the Conversion
           Price shall be proportionately increased.

           (b) If, prior to the conversion of all shares of Series B Preferred
           Stock, there shall be any merger, consolidation, exchange of shares,
           recapitalization, reorganization, or other similar event, as a result
           of which shares of Common Stock of the Corporation shall be changed
           into the same or a different number of shares of the same or another
           class or classes of stock or securities of the Corporation or another
           entity, then the holders of Series B Preferred Stock shall thereafter
           have the right to purchase and receive upon conversion of shares of
           Series B Preferred Stock, upon the basis and upon the terms and
           conditions specified herein and

                                   -6-     
<PAGE>
 
                    in lieu of the shares of Common Stock immediately
                    theretofore issuable upon conversion, such shares of stock
                    and/or securities as may be issued or payable with respect
                    to or in exchange for the number of shares of Common Stock
                    immediately theretofore purchasable and receivable upon the
                    conversion of shares of Series B Preferred Stock held by
                    such holders had such merger, consolidation, exchange of
                    shares, recapitalization or reorganization not taken place,
                    and in any such case appropriate provisions shall be made
                    with respect to the rights and interests of the holders of
                    the Series B Preferred Stock to the end that the provisions
                    hereof (including, without limitation, provisions for
                    adjustment of the Conversion Price and of the number of
                    shares issuable upon conversion of the Series B Preferred
                    Stock) shall thereafter be applicable, as nearly as may be
                    practicable in relation to any shares of stock or securities
                    thereafter deliverable upon the exercise hereof. The
                    Corporation shall not effect any transaction described in
                    this subsection unless the resulting successor or acquiring
                    entity (if not the Corporation) assumes by written
                    instrument the obligation to deliver to the holders of the
                    Series B Preferred Stock such shares of stock and/or
                    securities as, in accordance with the foregoing provisions,
                    the holders of the Series B Preferred Stock may be entitled
                    to purchase.

                    (c) If any adjustment under this subsection would create a
                    fractional share of Common Stock or a right to acquire a
                    fractional share of Common Stock, such fractional share
                    shall be disregarded and the number of shares of Common
                    Stock issuable upon conversion shall be the next higher
                    number of shares.

               10. Redemption Privilege. The Corporation shall have the right, 
                   --------------------
               in its sole discretion, to redeem in whole or in part any shares
               of Series B Preferred Stock submitted for conversion. The
               redemption price per share of Common Stock after conversion of
               the Series B Preferred Stock shall be calculated as 133% of the
               face value plus any accrued Additional Discount.

          E.   Voting. Except as otherwise provided below or by the General 
               ------
          Corporation Law of the State of Nevada, the holders of the Series B
          Preferred Stock shall have no voting power whatsoever, and no holder
          of Series B Preferred Stock shall vote or otherwise participate in any

                                      -7-
<PAGE>
 
            proceeding in which actions shall be taken by the Corporation
            or the shareholders thereof or be entitled to notification
            as to any meeting of the Board of Directors or the shareholders.

     Notwithstanding the above, Corporation shall provide holders of the Series
B Preferred Stock ("Holders") with notification of any meeting of the
shareholders regarding any major corporate events affecting the Corporation. In
the event of any taking by the Corporation of a record of its shareholders for
the purpose of determining shareholders who are entitled to receive payment of
any dividend or other distribution, any right to subscribe for, purchase or
otherwise acquire any share of any class or any other securities or property
(including by way of merger, consolidation or reorganization), or to receive any
other right, or for the purpose of determining shareholders who are entitled to
vote in connection with any proposed sale, lease or conveyance of all or
substantially all of the assets of the Corporation, or any proposed liquidation,
dissolution or winding up of the Corporation, the Corporation shall mail a
notice to the Holders, at least ten (10) days prior to the record date specified
therein, of the date on which any such record is to be taken for the purpose of
such dividend, distribution, right or other event, and a brief statement
regarding the amount and character of such dividend, distribution, right or
other event to the extent known at such time.

     To the extent that, under Nevada law, the vote of the Holders, voting
separately as a class, is required to authorize a given action of the
Corporation, the affirmative vote or consent of the Holders of at least a
majority of the shares of the Series B Preferred Stock represented at a duly
held meeting at which a quorum is present or by written consent of a majority of
the shares of Series B Preferred Stock (except as otherwise may be required
under Nevada law) shall constitute the approval of such action by the class. To
the extent that under Delaware law the Holders are entitled to vote on a matter
with holders of Common Stock, voting together as one (1) class, each share of
Series B Preferred Stock shall be entitled to a number of votes equal to the
number of shares of Common Stock into which it is then convertible using the
record date for the taking of such vote of stockholders as the date as of which
the Conversion Price is calculated. The Holders also shall be entitled to notice
of all shareholder meetings or written consents with respect to which they would
be entitled to vote, which notice would be provided pursuant to the
Corporation's by-laws and applicable statutes.

          F. Protective Provisions. So long as shares of Series B Preferred
             ---------------------
          Stock are outstanding, the Corporation shall not, without first
          obtaining the approval (by vote or written consent, as provided by
          law) of the Holders of at least seventy-five percent (75%) of the
          then outstanding shares of Series B Preferred Stock:
              
                                      -8-
<PAGE>
 
               (a) alter or change the rights, preferences or privileges of
               the Series B Preferred Stock so as to affect adversely the
               Series B Preferred Stock;

               (b) create any new class or series of stock or issue any
               capital stock senior to or having a preference over or parity
               with the Series B Preferred Stock with respect to dividends,
               payments upon Liquidation (as provided for in Section B of
               this Designation) or redemption, except for a class of stock
               approved by WS Marketing & Financial Services, Inc. d/b/a
               SMS Capital Services, or increase the number of authorized
               shares of Series B Preferred Stock or change the Stated
               Value thereof;

               (c) do any act or thing not authorized or contemplated by
               this Designation which would result in taxation of the
               holders of shares of the Series B Preferred Stock under 
               Section 305 of the Internal Revenue Code of 1986, as
               amended (or any comparable provision of the Internal
               Revenue Code as hereafter from time to time amended); or
               
               (d) enter into a merger in which the Corporation is not the
               surviving corporation; provided, however, that the
               provisions of this subparagraph (d) shall not be applicable to
               any such merger if the authorized capital stock of the
               surviving corporation immediately after such merger shall
               include only classes or series of stock for which no such
               consent or vote would have been required pursuant to this
               section if such class or series had been authorized by the
               Corporation immediately prior to such merger or which
               have the same rights, preferences and limitations and
               authorized amount a class or series of stock of the
               Corporation authorized (with such consent or vote of the
               Series B Preferred Stock) prior to such merger and
               continuing as an authorized class or series at the time
               thereof.

     G. Status of Converted Stock. In the event any shares of Series B
        -------------------------
     Preferred Stock shall be converted as contemplated by this Designation,
     the shares so converted shall be canceled, shall return to the status of
     authorized but unissued Preferred Stock of no designated class or series,
     and shall not be issuable by the Corporation as Series B Preferred Stock.

               H. Taxes. All shares of Common Stock issued upon conversion of 
                  -----
               Series B Preferred Stock will be validly issued, fully paid and
               nonassessable. The Corporation shall pay any and all documentary
               stamp or similar issue or transfer taxes that may be payable in
               respect of any issue or delivery of shares of Common Stock on
               conversion of Series B Preferred Stock pursuant hereto. The
               Corporation shall not, however, be required to pay any tax which
               may be payable in respect of any transfer involved in the issue
               and delivery of shares of Common Stock in a name other than that
               in which the Series B Preferred Stock so converted were
               registered, and no such issue or delivery shall be made unless
               and until the person requesting such transfer has paid to the
               Corporation the amount of any such tax or has established to the
               satisfaction of the Corporation that such tax has been paid or
               that no such tax is payable. The Corporation shall adjust the
               amount of dividends paid or accrued so as to indemnify the
               holders of Preferred Stock against any withholding or similar tax
               in respect of such dividends.

          FURTHER RESOLVED, that the statements contained in the foregoing 
resolutions creating and designating the said Series B Preferred Stock and 
fixing the number, powers, preferences and relative, optional, participating, 
and other special rights and the qualifications, limitations, restrictions, and 
other distinguishing characteristics thereof shall, upon the effective date of 
said series, be deemed to be included in and be a part of the certificate of 
incorporation of the Corporation pursuant to the provisions the General 
Corporation Law of the State of Nevada.

entitled to be paid out of the assets of the Corporation available for
distribution to its shareholders, whether from capital, surplus or earnings,
before any payment shall be made to the holders of shares of the Common Stock or
upon any other series of Preferred Stock of the Corporation with a liquidation
preference subordinate to the liquidation preference of the Series A Preferred
Stock and the Series B Preferred Stock, an amount per share equal to the sum of
(i) the Stated Value and (ii) an amount equal to zero percent (0%) of the Stated
Value multiplied by the fraction N/365, where N equals the number of days
elapsed since full payment for the shares of Series C Preferred Stock was
deposited with the escrow agent for the offering of the Series C Preferred
Stock. If, upon any Liquidation of the Corporation, the assets of the
Corporation available for distribution to its shareholders shall be insufficient
to pay the holders of shares of the Series C Preferred Stock and the holders of
any other series of Preferred Stock with a liquidation preference equal to the
liquidation preference of the Series C Preferred Stock the full amounts to which
they shall respectively be entitled, the holders of shares of the Series C
Preferred Stock and the holders of any other series of Preferred Stock with
liquidation preference equal to the liquidation preference of the Series C
Preferred Stock shall receive all of the assets of the Corporation available for
distribution and each such holder of shares of the Series C Preferred Stock and
the holders of any other series of Preferred Stock with a liquidation preference
equal to the liquidation preference of the Series C Preferred Stock shall share
ratably in any distribution in accordance with the amounts due such
shareholders. After payment shall have been made to the holders of shares of the
Series C Preferred Stock of the full amount to which they shall be entitled, as
aforesaid, the holders of shares of the Series C Preferred Stock shall be
entitled to no further distributions thereon and the holders of shares of the
Common Stock and of shares of any other series of stock of the Corporation shall
be entitled to share, according to their respective rights and preferences, in
all remaining assets of the Corporation available for distribution to its
shareholders.

                2. A merger or consolidation of the Corporation with or into any
other corporation, or a sale, lease, exchange, or transfer of all or any part of
the assets of the Corporation which shall not in fact result in the liquidation
(in whole or in part) of the Corporation and the distribution of its assets to
its shareholders shall not be deemed to be a voluntary or involuntary
liquidation (in whole or in part), dissolution, or winding-up of the
Corporation.

     D.  Conversion of Series C Preferred Stock.
         --------------------------------------

         The holders of Series C Preferred Stock shall have the following
conversion rights:

                1. Right to Convert. Fifty percent (50%) of each share of Series
                   ----------------
C Preferred Stock shall be convertible, on the earlier of (i) the effective date
of registration of the underlying Common Stock of the Corporation or (ii) one
hundred and twenty (120) calendar days after the closing of the offering of the
Series C Preferred Stock (the "Closing"), and at the Conversion Prices set forth
below, into fully paid and nonassessable shares of Common Stock, and the
remaining fifty percent (50%) of each share of Series C Preferred Stock all be
convertible on

                                      -2-
<PAGE>
 
the earlier of (x) the forty-fifth (45th) day after the effective date of
registration of the underlying Common Stock of the Corporation, or (y) one
hundred and sixty-five (165) calendar days after Closing, at the Conversion
Prices set forth below (sometimes deferred to herein as "Conversion Shares").

          2. Mechanics of Conversion. Each holder of Series C Preferred
            ------------------------
Stock who desires to convert the same into shares of Common Stock shall provide
notice ("Conversion Notice") via telecopy (facsimile) to the Corporation. The
original Conversion Notice and the certificate or certificates representing the
Series C Preferred Stock for which conversion is elected, shall be delivered to
the Corporation by international courier, duly endorsed. The date upon which a
Conversion Notice is received by the Corporation shall be a "Notice Date."

     Upon receipt by the Corporation of a facsimile copy of a Conversion Notice,
the Corporation shall immediately send to the holder, via telecopy (facsimile),
a confirmation of receipt of the Conversion notice which shall specify that the
Conversion Notice has been received and the name and telephone number of a
contact person at the Corporation whom the holder should contact regarding
information related to the conversion. The Corporation shall use all reasonable
efforts to issue and deliver within three (3) business days after the Notice
Date, to such holder of Series C Preferred Stock at the address of the holder on
the stock books of the Corporation, a certificate or certificates for the number
of shares of Common Stock to which the holder shall be entitled as aforesaid;
provided that the original shares of Series C Preferred Stock to be converted
are received by the transfer agent or the Corporation within three (3) business
days after the Notice Date and the person or persons entitled to receive the
shares of Common Stock issuable upon such conversion shall be treated for all
purposes as the record holder or holders of such shares of Common Stock on such
date. If the original certificate(s) representing the shares of Series C
Preferred Stock to be converted are not received by the transfer agent or the
Corporation within three (3) business days after the Notice Date, the Conversion
Notice shall become null and void.

          3. Lost or Stolen Certificates. Upon receipt by the Corporation of
             ---------------------------
evidence of the loss, destruction, theft or mutilation of any Series C Preferred
Stock certificates (the "Certificates") and (in the case of loss, theft or
destruction) of indemnity or security reasonably satisfactory to the
Corporation, and upon surrender and cancellation of the Certificates, if
mutilated, the Corporation shall execute and deliver new Series C Preferred
Stock Certificates of like tenor and date. However, the Corporation shall not be
obligated to re-issue such lost or stolen Series C Preferred Stock Certificates
if the holder thereof contemporaneously requests the Corporation to convert such
Series C Preferred Stock into Common Stock, in which event the Corporation shall
be entitled to rely on an affidavit of loss, destruction or theft of the Series
C Preferred Stock Certificate or, in the case of mutilation, tender of the
mutilated certificate, and shall issue the Conversion Shares.

          4. Conversion Dates. The shares of Series C Preferred Stock shall
             ----------------
become convertible into shares of Common Stock as stated in Paragraph D.1.
above. Each notice

                                      -3-
<PAGE>
 
upon which a holder elects to convert Series C Preferred Stock shall be 
considered a Conversion Date with respect to such stock and the shares of Common
Stock into which such stock is converted.

               5.   Conversion Formula/Conversion Price.  Each share of Series C
                    -----------------------------------
Preferred Stock shall be convertible into the number of shares of Common Stock
in accordance with the following formula (the "Conversion Formula"):

                      [(.00) x (N/365) x (1,000) + 1,000]
                      -----------------------------------

                               Conversion price

where,

            N=     the number of days between (i) the date that, in connection
                   with the consummation of the initial purchase by holder of
                   shares of Series C Preferred Stock from the Corporation, the
                   escrow agent first had in its possession funds representing
                   full payment for the shares of Series C Preferred Stock being
                   converted, and (ii) the Notice Date.

     Conversion 
     Price =       Discount Price or the Ceiling Price, whichever is less, but 
                   in no event shall the Conversion Price be less than the
                   amount derived by multiplying the Floor Price by 75%.

     Discount
     Price=        25% off of the five (5)-day average Closing Bid Price for the
                   Corporation's Common Stock immediately before Conversion
                   Date.

     Ceiling
     Price=        $3.94 per share.

     Floor Price=  $2.50 per share of the Corporation's Common Stock with the 
                   agreement to adjust the floor should the Corporation's Common
                   Stock trade less than $2.50 per share for five (5)
                   consecutive trading days prior to the conversion dates
                   herein. The adjusted floor shall then be the lowest Closing
                   Bid Price for the Corporation's Common Stock during such five
                   (5)-day period from which the Holder shall be entitled to the
                   Additional Discount.

     For purposes hereof, the term "Closing Bid Price" shall mean the closing 
bid price for the Corporation's Common Stock on the NASD Electronic Bulletin 
Board, or if no longer traded thereon, the closing bid price on the principal 
national securities exchange or quotation system on

                                      -4-


<PAGE>
 
which the Common Stock is so traded. The holder shall be entitled to an 
additional discount privilege equal to one percent (1%) per month or fraction of
a month off the five (5) day average closing bid price for the Corporation's 
Common Stock immediately before the Conversion Date, from the time of Closing 
until the effective date of registration of the underlying Common Stock for any 
conversions thirty (30) days after the effective date of registration of the 
underlying Common Stock and one-half percent (1/2%) per month or fraction of a 
month off the five (5) day average closing bid price for the Corporation's 
Common Stock immediately before the Conversion Date for any conversions 
thereafter ("Additional Discount").

          6.  Automatic Conversion. Each share of Series C Preferred Stock
              --------------------
outstanding on June 1, 2001 automatically shall be converted into Common Stock 
on such date in accordance with the Conversion Formula and the Conversion Price 
then in effect, and June 1, 2001 shall be deemed to be the Notice Date with 
respect to such conversion.

          7.  Forced Conversion. In the event the Floor Price is reached for the
              -----------------
Corporation's Common Stock for five (5) consecutive trading days, the 
Corporation shall have the right, but not the obligation, to require the holders
of Series C Preferred Stock to convert the Series C Preferred Stock into Common 
Stock at such time, at the Conversion Price then in effect, and the date upon 
which the Floor Price has been reached for the Corporations Common Stock for 
five (5) consecutive trading days shall be deemed to be the Notice Date with 
respect to such conversion.

          8.  No Fractional Shares. If any conversion of the Series C Preferred
              --------------------
Stock would create a fractional share of Common Stock or a right to acquire a 
fractional share of Common Stock, such fractional share shall be disregarded and
the number of shares of Common Stock issuable upon conversion, if the aggregate,
shall be the next higher number of shares

          9.  Reservation of Stock Issuable Upon Conversion. The Corporation 
              ---------------------------------------------
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series C Preferred Stock, such number of its shares of Common
Stock as shall from time to time be sufficient to effect the conversion of all
then outstanding shares of the Series C Preferred Stock; and if at any time the
number of authorized but unissued shares of Common Stock shall not be
sufficient to effect the conversion of all then outstanding shares of the Series
C Preferred Stock, the Corporation will take such corporate action as may be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purpose.

         10.  Adjustment to Conversion Price.
              ------------------------------
              
              (a)  If, prior to the conversion of all shares of Series C 
Preferred Stock, the number of outstanding shares of Common Stock is increased 
by a stock split, stock dividend, or other similar event, the Conversion Price 
shall be proportionately reduced, or if the number of outstanding shares of 
Common Stock is decreased by a combination or reclassification 

                                      -5-
<PAGE>
 
of shares, or other similar event, the Conversion Price shall be proportionately
increased.

          (b)  If, prior to the conversion of all shares of Series C Preferred
Stock, there shall be any merger, consolidation, exchange of shares,
recapitalization, reorganization, or other similar event, as a result of which
shares of Common Stock of the Corporation shall be changed into the same or a
different number of shares of the same or another class or classes of stock or
securities of the Corporation or another entity, then the holders of Series C
Preferred Stock shall thereafter have the right to purchase and receive upon
conversion of shares of Series C Preferred Stock, upon the basis and upon the
terms and conditions specified herein and in lieu of the shares of Common Stock
immediately theretofore issuable upon conversion, such shares of stock and/or
securities as may be issued or payable with respect to or in exchange for the
number of shares of Common Stock immediately theretofore purchasable and
receivable upon the conversion of shares of Series C Preferred Stock held by
such holders had such merger, consolidation, exchange of shares,
recapitalization or reorganization not taken place, and in any such case
appropriate provisions shall be made with respect to the rights and interests of
the holders of the Series C Preferred Stock to the end that the provisions
hereof (including, without limitation, provisions for adjustment of the
Conversion Price and of the number of shares issuable upon conversion of the
Series C Preferred Stock) shall thereafter be applicable, as nearly as may be
practicable in relation to any shares of stock or securities thereafter
deliverable upon the exercise hereof. The Corporation shall not effect any
transaction described in this subsection unless the resulting successor or
acquiring entity (if not the Corporation) assumes by written instrument the
obligation to deliver to the holders of the Series C Preferred Stock such shares
of stock and/or securities as, in accordance with the foregoing provisions, the
holders of the Series C Preferred Stock may be entitled to purchase.

          (c)  If any adjustment under this subsection would create a fractional
share of Common Stock or a right to acquire a fractional share of Common Stock,
such fractional share shall be disregarded and the number of shares of Common
Stock issuable upon conversion shall be the next higher number of shares.

     11.  Redemption Privilege.  The Corporation shall have the right, in its
          --------------------
sole discretion, to redeem, prior to receipt of the Notice of Conversion, in
whole or in part any shares of Series C Preferred Stock. The redemption price
shall be the greater of (i) 133% of the Stated Value of the Series C Preferred
Stock or (ii) the amount derived by multiplying (x) the number of shares of the
Corporation's Common Stock into which the Series C Preferred Shares could have
been converted calculated as of the date of the Notice of Conversion, by the
closing asking price of the Corporation's Common Stock as of the date of Notice
of Conversion. The Corporation shall not have a redemption privilege if the
Common Stock is trading above $3.50 per share unless the Holder agrees in
writing to allow the Corporation to redeem such shares.

     E.   Voting.  Except as otherwise provided below or by the General
          ------
Corporation Law of the State of Nevada, the holders of the Series C Preferred
Stock shall have no voting power whatsoever, and no holder of Series C Preferred
Stock shall vote or otherwise participate in any proceeding in which actions
shall be taken by the Corporation or the shareholders

                                      -6-
<PAGE>
 
thereof or be entitled to notification as to any meeting of the Board of 
Directors or the shareholders.

     Notwithstanding the above, Corporation shall provide holders of the Series 
C Preferred Stock ("Holders") with notification of any meeting of the 
shareholders regarding any major corporate events affecting the Corporation. In 
the event of any taking by the Corporation of a record of its shareholders for 
the purpose of determining shareholders who are entitled to receive payment of 
any dividend or other distribution, any right to subscribe for, purchase or 
otherwise acquire any share of any class or any other securities or property 
(including by way of merger, consolidation or reorganization), or to receive any
other right, or for the purpose of determining shareholders who are entitled to 
vote in connection with any proposed sale, lease or conveyance of all or 
substantially all of the assets of the Corporation, or any proposed liquidation,
dissolution or winding up of the Corporation, the Corporation shall mail a 
notice to the Holders, at least ten (10) days prior to the record date specified
therein, of the date on which any such record is to be taken for the purpose of
such dividend, distribution, right or other event, and a brief statement
regarding the amount and character of such dividend, distribution, right or
other event to the extent known at such time.

     To the extent that, under Nevada law, the vote of the Holders, voting 
separately as a class, is required to authorize a given action of the 
Corporation, the affirmative vote or consent of the Holders of at least a 
majority of the shares of the Series C Preferred Stock represented at a duly 
held meeting at which a quorum is present or by written consent of a majority of
the shares of Series C Preferred Stock (except as otherwise may be required 
under Nevada law) shall constitute the approval of such action by the class. To 
the extent that under Nevada law the HOlders are entitled to vote on a matter 
with holders of Common Stock, voting together as one (1) class, each share of 
Series C Preferred Stock shall be entitled to a number of votes equal to the 
number of shares of Common Stock into which it is then convertible using the 
record date for the taking of such vote of stockholders as the date as of which 
the Conversion Price is calculated. The Holders also shall be entitled to notice
of all shareholder meetings or written consents with respect to which they would
be entitled to vote, which notice would be provided pursuant to the
Corporation's by-laws and applicable statutes.

           F.  Protective Provisions. So long as shares of Series C Preferred 
               ---------------------
Stock are outstanding, the Corporation shall not, without first obtaining the 
approval (by vote or written consent, as provided by law) of the Holders of at 
least seventy-five percent (75%) of the then outstanding shares of Series C 
Preferred Stock:

               (a)  alter or change the rights, preferences or privileges of the
Series C Preferred Stock so as to affect adversely the Series C Preferred Stock;

               (b)  create any new class or series of stock or issue any capital
stock senior to or having a preference over or parity with the Series C 
Preferred Stock with respect to dividends, payments upon Liquidation (as 
provided for in Section B of this Designation) or redemption, or increase the 
number of authorized shares of Series C Preferred Stock or change the Stated 
Value thereof;

                                      -7-
<PAGE>
 
               (c)  do any act or thing not authorized or contemplated by this 
Designation which would result in taxation of the holders of shares of the 
Series C Preferred Stock under Section 305 of the Internal Revenue Code of 1986,
as amended (or any comparable provision of the Internal Revenue Code as 
hereafter from time to time amended); or

               (d)  enter into a merger in which the Corporation is not the 
surviving corporation; provided, however, that the provisions of this 
subparagraph (d) shall not be applicable to any such merger if the authorized 
capital stock of the surviving corporation immediately after such merger shall 
include only classes or series of stock for which no such consent or vote would
have been required pursuant to this section if such class or series had been
authorized by the Corporation immediately prior to such merger or which have the
same rights, preferences and limitations and authorized amount as a class or
series of stock of the Corporation authorized (with such consent or vote of the
Series C Preferred Stock) prior to such merger and continuing as an authorized
class or series at the time thereof.

          G.  Status of Converted Stock.  In the event any shares of Series C 
              -------------------------
Preferred Stock shall be converted as contemplated by this Designation, the 
shares so converted shall be canceled, shall return to the status of authorized 
but unissued Preferred Stock of no designated class or series, and shall not be 
issuable by the Corporation as Series C Preferred Stock.

          H.  Taxes.  All shares of Common Stock issued upon conversion of 
              -----
Series C Preferred Stock will be validly issued, fully paid and nonassessable. 
The Corporation shall pay any and all documentary stamp or similar issue or 
transfer taxes that may be payable in respect of any issue or delivery of shares
of Common Stock on conversion of Series C Preferred Stock pursuant hereto. The 
Corporation shall not, however, be required to pay any tax which may be payable 
in respect of any transfer involved in the issue and delivery of shares of 
Common Stock in a name other than that in which the Series C Preferred Stock so 
converted were registered, and no such issue or delivery shall be made unless 
and until the person requesting such transfer has paid to the Corporation the 
amount of any such tax or has established to the satisfaction of the Corporation
that such tax has been paid or that no such tax is payable. The Corporation 
shall adjust the amount of dividends paid or accrued so as to indemnify the 
holders of Preferred Stock against any withholding or similar tax in respect of 
such dividends.

     FURTHER RESOLVED, that the statements contained in the foregoing 
resolutions creating and designating the said Series C Preferred Stock and 
fixing the number, powers, preferences and relative, optional, participating, 
and other special rights and the qualifications, limitations, restrictions, and 
other distinguishing characteristics thereof shall, upon the effective date of 
said series, be deemed to be included in and be a part of the certificate of 
incorporation of the Corporation pursuant to the provisions the General 
Corporation Law of the State of Nevada.

the Committee which, except as provided herein, shall be comprised of one or

repeal such administrative rules, guidelines and practices governing the Plan as
it shall, from time to time, deem advisable, to interpret the terms and 
provisions of the Plan and any Option issued under the Plan and to otherwise 
supervise the administration of the Plan.  The Committee's policies and 
procedures may differ with respect to Options granted at different times or to 
different Participants.

     Any determination made by the Committee pursuant to the provisions of the 
Plan shall be made in its sole discretion.  All decisions made by the Committee 
pursuant to the provisions of the Plan shall be final and binding on all 
persons, including the Company and Participants.  Any determination shall not be

                             STOCK SUBJECT TO PLAN
                             ---------------------

     4.1  Number of Shares. Subject to the adjustment under Section 4.5, the
          ----------------
total number of shares of Common Stock reserved and available for issuance 
pursuant to Options under the Plan shall be three hundred thousand (300,000) 
shares of Common Stock authorized for issuance on the Effective Date. Such 
shares may consist, in whole or in part, of authorized and unissued shares or
treasury shares.

     4.2  Release of Shares. The Committee shall have full authority to 
          -----------------
determine the number of shares of Common Stock available for Stock Options, and 
in its discretion may include (without limitation) as available for distribution
any shares of Common Stock that have ceased to be subject to Stock Options, any 
shares of Common Stock subject to any Stock Options that are forfeited, any
Stock Options that otherwise terminate without issuance of shares of Common
Stock being made to the Participant, or any shares (whether or not restricted)
of Common Stock that are received by the Company in connection with the exercise
of a Stock Option, including the satisfaction of any tax liability or the
satisfaction of a tax withholding obligation. If any shares could not again be
available for Options to a particular Participant under applicable law, such
shares shall be available exclusively for Options to Participants who are not
subject to such limitations.

     4.3  Restrictions on Shares. Shares of Common Stock issued upon exercise
          ----------------------
of an Option shall be subject to the terms and conditions specified herein and 
to such other terms, conditions and restrictions as the Committee in its 
discretion may determine or provide in the Option Agreement. The Company shall 
not be required to issue or deliver any certificates for shares of Common Stock,
cash or other property prior to (i) the listing of such shares on any stock 
exchange, NASDAQ or other public market on which the Common Stock may then be 
listed (or regularly traded), (ii) the completion of any registration or 
qualification of such shares under federal or state law, or any ruling or 
regulation of any government body which the Committee determines to be 
necessary or advisable, and (iii) the satisfaction of any applicable withholding
obligation in order for the Company or an Affiliate to obtain a deduction with 
respect to the exercise of an Option. The Company may cause any certificate for 
any share of Common Stock to be delivered to be properly marked with a legend or
other notation reflecting the limitations on transfer of such Common Stock as 
provided in the Plan or as the Committee may otherwise require. The Committee
may require any person exercising an Option to make such representations and
furnish such information as it may consider appropriate in connection with the
issuance or delivery of the shares of Common Stock in compliance with applicable
law or otherwise. Fractional shares shall not be delivered, but shall be rounded
to the next lower whole number of shares.

     4.4. Reasonable Efforts To Register. If there has been a Public Offering,
          ------------------------------
the Company will register under the Securities Act the Common Stock delivered or
deliverable pursuant to Options on Commission Form S-8 if available to the 
Company

                                       6

<PAGE>
 
for this purpose (or any successor or alternate form that is substantially 
similar to that form to the extent available to effect such registration), in 
accordance with the rules and regulations governing such forms, as soon as such 
forms are available for registration to the Company for this purpose.  The 
Company will use its reasonable efforts to cause the registration statement to 
become effective as soon as possible and will file such supplements and 
amendments to the registration statement as may be necessary to keep the 
registration statement in effect until the earliest of (a) one year following 
the expiration of the Option Period of the last Option outstanding, (b) the date
the Company is no longer a reporting company under the Exchange Act and (c) the 
date all Participants have disposed of all shares delivered pursuant to any 
Option.  The Company may delay the foregoing obligation if the Committee 
reasonably determines that any such registration would materially and adversely 
affect the Company's interests or if there is no material benefit to 
Participants.

     4.5  Adjustments.  In the event of a stock dividend, stock split, 
          -----------
combination or exchange of shares, recapitalization or other change in the 
capital structure of the Company, corporate separation or division of the
Company (including, but not limited to, a split-up, spin-off, split-off or
distribution to Company stockholders other than a normal cash dividend), sale by
the Company of all or a substantial portion of its assets (measured on either a
stand-alone or consolidated basis), reorganization, rights offering, a partial
or complete liquidation, or any other corporate transaction, Company stock
offering or event involving the Company and having an effect similar to any of
the foregoing, then the Committee shall adjust or substitute, as the case may
be, the number of shares of Common Stock available for Options under the Plan,
the number of shares of Common Stock covered by outstanding Options, the
exercise price per share of outstanding Options, and any other characteristics
or terms of the Options as the Committee shall deem necessary or appropriate to
reflect equitably the effects of such changes to the Participants; provided,
however, that any fractional shares resulting from such adjustment shall be
eliminated by rounding to the next lower whole number of shares with appropriate
payment for such fractional share as shall reasonably be determined by the
Committee.

     4.6  Limited Transfer During Offering.  In the event there is an effective
          --------------------------------
registration statement under the Securities Act pursuant to which shares of 
Common Stock shall be offered for sale in an underwritten offering, a 
Participant shall not, during the period requested by the underwriters managing 
the registered public offering, effect any public sale or distribution of shares
received directly or indirectly pursuant to an exercise of an Option.

     5.2  Grant and Exercise.  Each person who is elected as a Director and
          ------------------
constitutes an eligible Participant shall be granted an Option on the effective 
date of their becoming an eligible Participant to purchase twenty-five thousand 
(25,000) shares of Common Stock without further action by the Board or the 
Committee.  Each person who is subsequently re-elected to a second term as a 
Director and continues to constitute an eligible Participant shall, on the date 
of such re-election, without further action by the Board or the Committee, be 
granted an option to purchase an additional twenty-five thousand (25,000) shares
of Common Stock.  Each person who is subsequently re-elected to a third term as 
a Director and continues to constitute an eligible Participant shall, on the 
date of such re-election, without further action by the Board or the Committee,
be granted an Option to Purchase fifty thousand (50,000) shares of Common Stock.
If the number of shares of Common Stock available to grant under the Plan on a 
scheduled date of grant is insufficient to make all automatic grants required to
be made pursuant to the Plan on such date, then each eligible Director shall 
receive an Option to purchase a pro rata number of the remaining shares of 
Common Stock available under the Plan; provided further, however, that if such 
proration results in fractional shares of Common Stock, then such Option shall 
be rounded down to the nearest number of whole shares of Common Stock.  If there
is no whole number of shares remaining to be granted, then no grants shall be 
made under the Plan.  Each Option granted under the Plan shall be evidenced by 
an Agreement, in a form approved by the Committee, which shall embody the terms 
and conditions of such Option and which shall be subject to the express terms 
and conditions set forth in the Plan.  Such Agreement shall become effective 
upon execution by the Participant.

     5.3  Terms and Conditions.  Options shall be subject to such terms and 
          --------------------
conditions as shall be determined by the Committee, including in each case the 
following:

     (a)  Option Period.  The Option Period of each Option shall be five (5)

years.

     (b)  Option Price.  The Option Price per share of the Common Stock 
          ------------
purchasable under an Option shall be the Fair Market Value as of the Grant Date.

     (c)  Exercisability.  Unless an earlier time is specified in an Agreement,
          --------------
and subject to the provisions of Section 6.3, Options granted on the Effective 
Date of a Public Offering shall become fully exercisable upon the Grant Date and
Options granted thereafter shall become exercisable on the first anniversary of 
the Grant Date.  An Option only shall be exercisable during the Option Period.

     (d)  Method of Exercise.  Subject to the provisions of this Article V, a
          ------------------
Participant may exercise Stock Options, in whole or in part, at any time during 
the Option Period by the Participant's giving written notice of exercise on a 
form provided by the Committee (if available) to the Company specifying the 
number of shares of Common Stock subject to the Stock Option to be purchased.  
Except when waived by the Committee, such notice shall be accompanied by payment
in full of the purchase price by cash or check or such other form of payment 
as the Company may

                                       8
<PAGE>
 
accept. If approved by the Committee (including approval at the time of 
exercise), payment in full or in part may also be made (i) by delivering Common 
Stock already owned by the Participant having a total Fair Market Value on the 
date of such delivery equal to the Option Price; (ii) by the execution and 
delivery of a note or other evidence of indebtedness (and any security agreement
thereunder) satisfactory to the Committee and permitted in accordance with 
Section 5.3(e); (iii) by authorizing the Company to retain shares of Common 
Stock which would otherwise be issuable upon exercise of the Option having a 
total Fair Market Value on the date of delivery equal to the Option Price; (iv) 
by the delivery of cash or the extension of credit by a broker-dealer to whom 
the Participant has submitted a notice of exercise or otherwise indicated an 
intent to exercise an Option (in accordance with Part 220, Chapter II, Title 12 
of the Code of Federal Regulations, so-called "cashless" exercise); or (v) by 
certifying ownership of shares of Common Stock by the Participant to the 
satisfaction of the Committee for later delivery to the company as specified by 
the committee; or (vi) by any combination of the foregoing or by any other
method permitted by the Committee.

     (e)  Nontransferability of Options.  Except as provided herein or in an 
          -----------------------------  
Agreement, no Option or interest therein shall be transferable by the
Participant other than by will or by the laws of descent and distribution, and
all Options shall be exercisable during the Participant's lifetime only by the
Participant. If and to the extent transferability is permitted by Rule 16b-3 and
except as otherwise provided herein or by an Agreement, every Option granted
hereunder shall be freely transferable, but only if such transfer does not
result in liability under Section 16 of the Exchange Act to the Participant or
other Participants and is consistent with registration of the Option and sale of
Common Stock on Form S-8 (or a successor form) or the Committee's waiver of such
condition.

     5.4  Termination.  Unless otherwise provided in an Agreement or determined 
          -----------
by the Committee, if a Participant ceases to be a Director due to death, any 
unexpired and unexercised Stock Option held by such Participant shall thereafter
be fully exercisable for a period of ninety (90) days following the date of the
appointment of a Representative (or such other period or no period as the
Committee may specify) or until the expiration of the Option Period, whichever
period is the shorter. Unless otherwise provided in an Agreement or determined
by the Committee, if a Participant ceases to be a Director due to a Disability,
any unexpired and unexercisable Stock Option held by such Participant shall
thereafter be fully exercisable by the Participant for the period of ninety (90)
days (or such other period or no period as the Committee may specify)
immediately following the date the Participant ceases to be a Director or until
the expiration of the Option Period, whichever period is shorter, and the
Participant's death at any time following the date the Participant ceases to be
a Director due to Disability shall not affect the foregoing.

     Unless otherwise provided in an Agreement or determined by the Committee, 
if a Participant's directorship is terminated for any reason other than due to 
Participant's death or Disability, any Option held by such Participant shall 
thereupon terminate. Unless otherwise provided in an Agreement, the death or 
Disability of a 

                                       9

<PAGE>
 
Participant after a termination of Directorship otherwise provided herein shall 
not extend the exercisability of the time permitted to exercise an Option.

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

     6.1  Amendments and Termination.  The Board may amend, alter or discontinue
          --------------------------
the Plan at any time, but no amendment, alteration or discontinuation shall be 
made which would impair the rights of a Participant under a Stock Option, 
theretofore granted without the Participant's consent, except such an amendment 
(a) made to avoid an expense charge to the Company or an Affiliate, (b) made to 
cause the Plan to qualify for the exemption provided by Rule 16b-3, (c) to 
prevent the Plan from being disqualified from the exemption provided by Rule 
16b-3, or (d) made to permit the Company or an Affiliate a deduction under the
Code. In addition, no such amendment shall be made without the approval of the
Company's stockholders to the extent such approval is required by law or
agreement. Notwithstanding the foregoing, the Plan may not be amended more than
once every six (6) months to change the Plan provisions listed in section
(c)(2)(ii)(A) of Rule 16b-3, other than to comport with changes in the Code or
Rule 16b-3.

     The Committee may amend the Plan at any time subject to the same 
limitations (and exceptions to limitations) as applied to the Board and further 
subject to any approval or limitations the Board may impose.

     The Committee may amend the terms of any Stock Option theretofore granted, 
prospectively or retroactively, but no such amendment shall impair the rights of
any Participant without the Participant's consent or reduce an Option Price, 
except such an amendment made to cause the Plan or Award to qualify for the 
exemption provided by Rule 16b-3, avoid an expense charge to the Company or an 
Affiliate or qualify for a deduction.  The Committee's discretion to amend the 
Plan or Agreement shall be limited to the Plan's constituting a plan described
in section (c)(2)(ii) of Rule 16b-3.

     Subject to the above provisions, the Board shall have authority to amend 
the Plan to take into account changes in law and tax and accounting rules, as 
well as other developments, and to grant Awards which qualify for beneficial 
treatment under such rules without stockholder approval.  Notwithstanding 
anything in the Plan to the contrary, if any right under this Plan would cause a
transaction to be ineligible for pooling of interest accounting that would, but
for the right hereunder, be eligible for such accounting treatment, the
Committee may modify or adjust the right so that pooling of interest accounting
is available.

     6.2  General Provisions.
          ------------------

     (a)  Representation.  The Committee may require each person purchasing or 
          --------------
receiving shares pursuant to an Option to represent to and agree with the 
Company

                                      10
<PAGE>
 
in writing that such person is acquiring the shares without a view to the 
distribution thereof in violation of the Securities Act. The certificates for 
such shares may include any legend which the Committee deems appropriate to 
reflect any restrictions on transfer.

     (b)  Withholding.  If determined to be required to protect the Company, no 
          -----------
later than the date as of which an amount first becomes includable in the gross 
income of the Participant for Federal income tax purposes with respect to any 
Option, the Participant shall pay to the Company (or other entity identified by 
the Committee), or make arrangements satisfactory to the Company or other entity
identified by the Committee regarding the payment of, any Federal, state, local
or foreign taxes of any kind required by law to be withheld with respect to such
amount. Unless otherwise determined by the Committee, withholding obligations
may be settled with Common Stock, including Common Stock that is part of the
Option that gives rise to the withholding requirement, provided that any
applicable requirements under Section 16 of the Exchange Act are satisfied. The
obligations of the Company under the Plan shall be conditional on such payment
or arrangements, and the Company and its Affiliates shall, to the extent
permitted by law, have the right to deduct any such taxes from any payment
otherwise due to the Participant.

     (c)  Controlling Law.  The Plan and all Options made and actions taken 
          ---------------
thereunder shall be governed by and construed in accordance with the laws of the
State of Illinois (other than its law respecting choice of law) except to the 
extent the Nevada Revised Statutes would be mandatorily applicable. The Plan 
shall be construed to comply with all applicable law, and to avoid liability to 
the Company, an Affiliate or a Participant, including, without limitation, 
liability under Section 16(b) of the Exchange Act.

     (d)  Offset.  Any amounts owed to the Company or an Affiliate by the 
          ------
Participant of whatever nature may be offset by the Company from the value of 
any shares of Common Stock, cash or other thing of value under the Plan or an 
Agreement to be transferred to the Participant, and no shares of Common Stock, 
cash or other thing of value under the Plan or an Agreement shall be transferred
unless and until all disputes between the Company and the Participant have been 
fully and finally resolved and the Participant has waived all claims to such 
against the Company or an Affiliate.

     (e)  Fail-Safe.  With respect to persons subject to Section 16 of the 
          --------- 
Exchange Act, transactions under this Plan are intended to comply with all 
applicable conditions of Rule 16b-3 or Rule 16a-1(c)(3). To the extent any 
provision of the Plan or action by the Committee fails to so comply, it shall be
deemed null and void, to the extent permitted by law and deemed advisable by the
Committee. Moreover, in the event the Plan does not include a provision required
by Rule 16b-3 or Rule 16a-1(c)(3) to be stated therein, such provision (other 
than one relating to eligibility requirements, or the price and amount of 
Options) shall be deemed to be incorporated by reference into the Plan with 
respect to Participants subject to Section 16.

                   of at least 15 days thereof is provided before the date of 
                   cancellation;

              (2)  To provide that the securities of another entity be
                   substituted hereunder for the Common Stock and to make
                   equitable adjustment with respect thereto;

              (3)  To grant the Participant by giving notice during a pre-set

                   Company and to receive cash in an amount equal to the
                   amount by which the "Change in Control Price" (as defined in
                   Section 6.3(c)) per share of Common Stock on the date of such
                   election shall exceed the amount which the Participant must
                   pay to exercise the Option per share of Common Stock under 
                   the Option (the "Spread") multiplied by the number of shares
                   of Common Stock granted under the Option;

              (4)  To require the assumption of the obligation of the Company
                   under the Plan subject to appropriate adjustment; and

transaction reported on the principal exchange on which such shares are listed
or on NASDAQ during the sixty (60)-day period prior to and including the date of
a Change in Control, or (ii) if the Change in Control is the result of a
corporate transaction, the highest price per share of Common Stock paid in such
tender or exchange offer or a corporate transaction. To the extent that the
consideration paid in any such transaction described above consists all or in
part of securities or other non-cash consideration, the value of such securities
or other non-cash consideration shall be determined in the sole discretion of
the Committee.

that if the Committee does not consist solely of "Non-Employee Directors," as
defined in Rule 16b-3 as promulgated by the Securities and Exchange Commission

          (5) to determine the terms and conditions (including restrictions on
transfer as may be appropriate under Federal and state securities laws),

instruments evidencing the Stock Options, Stock Appreciation Rights, Limited

terminated without being exercised or (ii) any shares of Stock subject to any
Deferred Stock or Restricted Stock award granted hereunder are forfeited, such

Stock Option and such shares are returned to the Company in satisfaction of such
indebtedness, such shares shall again be available for issuance in connection
with future Awards under the Plan.

     (c) In the event of any merger, reorganization, consolidation,

granted under the Plan as may be determined by the Administrator, in its sole

be determined by the Administrator, in its sole discretion; provided, however,
that with respect to Incentive Stock Options, such adjustment shall be made in

used to determine the amount payable by the Company upon the exercise of any
Stock Appreciation Right or Limited Stock Appreciation Rights associated with
any Stock Option.

with the Company, in such form as the Administrator shall determine, which
agreement shall set forth, among other things, the exercise price of the option,
the term of the option and provisions regarding exercisability of the option
granted thereunder.

     The Stock Options granted under the Plan to Eligible Employees may be of
two types: (x) Incentive Stock Options and (y) Non-Qualified Stock Options.

     (b) The Administrator shall have the authority under this Section 5 to
grant any optionee Incentive Stock Options, Non-Qualified Stock Options, or both
types of Stock Options (in each case with or without Stock Appreciation Rights
or Limited Stock Appreciation Rights); provided, however, that Incentive Stock
Options may not be granted to any individual who is not an employee of the
Company, its Subsidiaries or Parent Corporation. To the extent that any Stock
Option does not qualify as an Incentive Stock Option, it shall constitute a
separate Non-Qualified Stock Option. More than one option may be granted to the
same optionee and be outstanding concurrently hereunder.

     (c) Stock Options granted under the Plan shall be subject to the following
terms and conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of the Plan, as the Administrator shall deem
desirable:

          (i)   Option Price. The option price per share of Stock purchasable
                ------------                                                 
under a Stock Option shall be determined by the Administrator in its sole
discretion at the time of grant but shall be not less than 100% of the Fair
Market Value of the Stock on such date, and shall not, in any event, be less
than the par value of the Stock.  The option price per share of Stock
purchasable under a Non-Qualified Stock Option may be less than 100% of such
Fair Market Value.  If an employee owns or is deemed to own (by reason of the
attribution rules applicable under Section 424(d) of the Code) more than 10% of
the combined voting power of all classes of stock of the Company or any Parent
Corpo  ration or Subsidiary and an Incentive Stock Option is granted to such
employee, the option

                                      -5-
<PAGE>
 
price of such Incentive Stock Option (to the extent required by the Code at the
time of grant) shall be no less than 110% of the Fair Market Value of the Stock
on the date such Incentive Stock Option is granted.

          (ii)  Option Term.  The term of each Stock Option shall be fixed by
                -----------                                                  
the Administrator, but no Stock Option shall be exercisable more than ten years
after the date such Stock Option is granted; provided, however, that if an
                                             --------  -------            
employee owns or is deemed to own (by reason of the attribution rules of Section
424(d) of the Code) more than 10% of the combined voting power of all classes of
stock of the Company or any Parent Corporation or Subsidiary and an Incentive
Stock Option is granted to such employee, the term of such Incentive Stock
Option (to the extent required by the Code at the time of grant) shall be no
more than five years from the date of grant.

          (iii) Exercisability.  Stock Options shall be exercisable at such time
                --------------                                                  
or times and subject to such terms and conditions as shall be determined by the
Administrator at or after grant; provided, however, that, except as provided
                                 --------  -------                          
herein or unless otherwise determined by the Administrator at or after grant,
Stock Options shall be exercisable one year following the date of grant of the
option, but in no case, less than six (6) months following the date of the grant
of the option. To the extent not exercised, installments shall accumulate and be
exercisable in whole or in part at any time after becoming exercisable but not
later than the date the Stock Option expires. The Administrator may provide, in
its discretion, that any Stock Option shall be exercisable only in installments,
and the Administrator may waive such installment exercise provisions at any time
in whole or in part based on such factors as the Administrator may determine in
its sole discretion.

          (iv)  Method of Exercise.  Subject to Section 5(c), Stock Options may
                ------------------                                             
be exercised in whole or in part at any time during the option period, by giving
written notice of exercise to the Company specifying the number of shares to be
purchased, accompanied by payment in full of the purchase price in cash or its
equivalent, as determined by the Administrator.  As determined by the
Administrator, in its sole discretion, payment in whole or in part may also be
made (i) in the form of unrestricted Stock already owned by the optionee, or, in
the case of the exercise of a Non-Qualified Stock Option, Restricted Stock
subject to an Award hereunder (based, in each case, on the Fair Market Value of
the Stock on the date the option is exercised), (ii) by cancellation of any
indebtedness owed by the Company to the optionee, (iii) by a full recourse
promissory note executed by the optionee, (iv) by requesting that the Company
withhold whole shares of Common Stock then issuable upon exercise of the Stock
Option (based on the Fair Market Value of the Stock on the date the option is
exercised), (v) by arrangement with a broker which is acceptable to the
Administrator where payment of the option price is made pursuant to an
irrevocable direction to the broker to deliver all or part of the proceeds from
the sale of the shares underlying the option to the Company, or (vi) by any
combination of the foregoing; provided, however, that in the case of an
                              --------  -------                        
Incentive Stock Option, the right to make payment in the form of already owned
shares may be authorized only at the time of grant.  Any payment in the form of
stock already owned by the optionee may be effected by use of an attestation
form approved by the Administrator.  If payment of the option exercise price of
a Non-Qualified Stock Option is made in whole or in part in the form of
Restricted Stock, the shares received upon the exercise of such Stock Option (to
the extent of the number of shares of Restricted Stock surrendered upon exercise
of such Stock Option) shall be restricted in accordance with the original terms
of the Restricted Stock award in question, except that the

                                      -6-
<PAGE>
 
Administrator may direct that such restrictions shall apply only to that number
of shares equal to the number of shares surrendered upon the exercise of such
option. An optionee shall generally have the rights to dividends and other
rights of a shareholder with respect to shares subject to the option only after
the optionee has given written notice of exercise, has paid in full for such
shares, and, if requested, has given the representation described in paragraph
(a) of Section 11.

     (d)  The Administrator may require the voluntary surrender of all or a
portion of any Stock Option granted under the Plan as a condition precedent to a
grant of a new Stock Option.  Subject to the provisions of the Plan, such new
Stock Option shall be exercisable at the price, during such period and on such
other terms and conditions as are specified by the Administrator at the time the
new Stock Option is granted; provided, however, that should the Administrator
                             --------  -------                                  
so require, the number of shares subject to such new Stock Option shall not be
greater than the number of shares subject to the surrendered Stock Option. Upon
their surrender, the Stock Options shall be canceled and the shares previously
subject to such canceled Stock Options shall again be available for grants of
Stock Options and other Awards hereunder.

     (e)  Loans.  The Company may make loans available to Stock Option holders
          -----  
in connection with the exercise of outstanding options granted under the Plan,
as the Administrator, in its discretion, may determine. Such loans shall (i) be
evidenced by promissory notes entered into by the Stock Option holders in favor
of the Company, (ii) be subject to the terms and conditions set forth in this
Section 5(e) and such other terms and conditions, not inconsistent with the
Plan, as the Administrator shall determine, (iii) bear interest, if any, at such
rate as the Administrator shall determine and (iv) be subject to Board approval.
In no event may the principal amount of any such loan exceed the sum of (x) the
exercise price less the par value of the shares of Stock covered by the option,
or portion thereof, exercised by the holder and (y) any Federal, state, and
local income tax attributable to such exercise.  The initial term of the loan,
the schedule of payments of principal and interest under the loan, the extent to
which the loan is to be with or without recourse against the holder with respect
to principal or interest and the conditions upon which the loan will become
payable in the event of the holder's termination of employment shall be
determined by the Administrator; provided, however, that the term of the loan,
                                 --------  -------                            
including extensions, shall not exceed seven years.  Unless the Administrator
determines otherwise, when a loan is made, shares of Common Stock having a Fair
Market Value at least equal to the principal amount of the loan shall be pledged
by the holder to the Company as security for payment of the unpaid balance of
the loan, and such pledge shall be evidenced by a pledge agreement, the terms of
which shall be determined by the Administrator, in its discretion; provided,
                                                                   -------- 
however, that each loan shall comply with all applicable laws, regulations and
- -------                                                                       
rules of the Board of Governors of the Federal Reserve System and any other
governmental agency having jurisdiction.

     (f)  Limits on Transferability of Options.
          ------------------------------------ 

          (i) Subject to Section 5(f)(ii), no Stock Option shall be transferable
by the optionee otherwise than by will or by the laws of descent and
distribution or, with respect to Non-Qualified Stock Options, pursuant to a
"qualified domestic relations order," as such term is defined in the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"). Incentive Stock

                                      -7-
<PAGE>
 
Options shall be exercisable, during the optionee's lifetime, only by the
optionee or, with respect to Non-Qualified Stock Options, in accordance with the
terms of a qualified domestic relations order.

          (ii) The Administrator may, in its discretion, authorize all or a
portion of the options (other than Incentive Stock Options) to be granted to an
optionee to be on terms which permit transfer by such optionee to (A) the
spouse, qualified domestic partner, children or grandchildren of the optionee
and any other persons related to the optionee as may be approved by the
Administrator ("Immediate Family Members"), (B) a trust or trusts for the
exclusive benefit of such Immediate Family Members, (C) a partnership or
partnerships in which such Immediate Family Members are the only partners, or
(D) any other persons or entities as may be approved by the Administrator,
provided that (x) there may be no consideration for any transfer unless approved
by the Administrator, (y) the stock option agreement pursuant to which such
options are granted must be approved by the Administrator, and must expressly
provide for transferability in a manner consistent with this Section 5(f)(ii),
and (z) subsequent transfers of transferred options shall be prohibited except
those in accordance with Section 5(f)(i) or expressly approved by the
Administrator. Following transfer, any such options shall continue to be subject
to the same terms and conditions as were applicable immediately prior to
transfer, provided that, except for purposes of Sections 5(g), (h) and (i) and
11(c) hereof, the terms "optionee," "Stock Option holder" and "Participant"
shall be deemed to refer to the transferee. The events of termination of
employment under Sections 5(g), (h) and (i) hereof shall continue to be applied
with respect to the original optionee, following which the options shall be
exercisable by the transferee only to the extent, and for the periods specified
under such sections unless the option agreement governing such options otherwise
provides. Notwithstanding the transfer, the original optionee will continue to
be subject to the provisions of Section 11(c) regarding payment of taxes,
including the provisions entitling the Company to deduct such taxes from amounts
otherwise due to such optionee. "Qualified domestic partner" for the purpose of
this Section 5(f)(ii) shall mean a domestic partner living in the same household
as the optionee and registered with, certified by or otherwise acknowledged by
the county or other applicable governmental body as a domestic partner or
otherwise establishing such status in any manner satisfactory to the
Administrator.

     (g)  Termination by Death.  If an optionee's employment with the Company,
          --------------------                                                
any Subsidiary or Parent Corporation terminates by reason of death, the Stock
Option may thereafter be immediately exercised, to the extent then exercisable
(or on such accelerated basis as the Administrator shall determine at or after
grant), by the legal representative of the estate or by the legatee of the
optionee under the will of the optionee, for a period of twelve months (or such
shorter period as the Administrator shall specify at grant) from the date of
such death or until the expiration of the stated term of such Stock Option,
whichever period is shorter.

     (h)  Termination by Reason of Disability.  If an optionee's employment with
          -----------------------------------                                   
the Company, any Subsidiary or Parent Corporation terminates by reason of
Disability, any Stock Option held by such optionee may thereafter be exercised,
to the extent it was exercisable at the time of such termination (or on such
accelerated basis as the Administrator shall determine at the time of grant),
for a period of twelve months (or such shorter period as the Administrator shall
specify at grant) from the date of such termination of employment or until the
expiration of the stated term of such Stock Option, whichever period is shorter;
provided, however, that, if the optionee dies within 
- --------  -------

                                      -8-
<PAGE>
 
such twelve-month period (or such shorter period as the Administrator shall
specify at grant) and prior to the expiration of the stated term of such Stock
Option, any unexercised Stock Option held by such optionee shall thereafter be
exercisable to the extent to which it was exercisable at the time of termination
for a period of twelve months (or such shorter period as the Administrator shall
specify at grant) from the time of death or until the expiration of the stated
term of such Stock Option, whichever period is shorter. In the event of a
termination of employment by reason of Disability, if an Incentive Stock Option
is exercised after the expiration of the exercise periods that apply for
purposes of Section 422 of the aeode, such Stock Option shall thereafter be
treated as a Non-Qualified Stock Option.

     (i) Other Termination.  Except as otherwise provided in this paragraph or
         -----------------                                                    
otherwise determined by the Administrator, if an optionee's employment with the
Company, any Subsidiary or Parent Corporation terminates for any reason other
than death or Disability, the Stock Option may be exercised until the earlier to
occur of (i) three months from the date of such termination or (ii) the
expiration of the stated term of such Stock Option.

     (j) Annual Limit on Incentive Stock Options.  To the extent that the
         ---------------------------------------                         
aggregate Fair Market Value (determined as of the date the Incentive Stock
Option is granted) of the shares of Stock with respect to which Incentive Stock
Options granted to an optionee under this Plan and all other option plans of the
Company, its Parent Corporation and any Subsidiary become exercisable for the
first time by the optionee during any calendar year exceeds $100,000, such Stock
Options shall be treated as Non-Qualified Stock Options.

Section 6.  Stock Appreciation Rights.

     (a) Grant and Exercise.  Stock Appreciation Rights and Limited Stock
         ------------------                                              
Appreciation Rights may be granted either alone ("Free Standing Rights") or in
conjunction with all or part of any Stock Option granted under the Plan
("Related Rights").  In the case of a Non-Qualified Stock Option, Related Rights
may be granted either at or after the time of the grant of such Stock Option.
In the case of an Incentive Stock Option, Related Rights may be granted only at
the time of the grant of the Incentive Stock Option.

     A Related Right or applicable portion thereof granted in conjunction with a
given Stock Option shall terminate and no longer be exercisable upon the
termination or exercise of the related Stock Option, except that, unless
otherwise provided by the Administrator at the time of grant, a Related Right
granted with respect to less than the full number of shares covered by a related
Stock Option shall only be reduced if and to the extent that the number of
shares covered by the exercise or termination of the related Stock Option
exceeds the number of shares not covered by the Stock Appreciation Right.

     A Related Right may be exercised by an optionee, in accordance with
paragraph (b) of this Section 6, by surrendering the applicable portion of the
related Stock Option.  Upon such exercise and surrender, the optionee shall be
entitled to receive an amount determined in the manner prescribed in paragraph
(b) of this Section 6. Stock Options which have been so surrendered, in

                                      -9-
<PAGE>
 
whole or in part, shall no longer be exercisable to the extent the Related
Rights have been so exercised.

     (b)  Terms and Conditions.  Stock Appreciation Rights shall be subject to
          --------------------                                                
such terms and conditions, not inconsistent with the provisions of the Plan, as
shall be determined from time to time by the Administrator, including the
following:

          (i)  Related Stock Appreciation Rights.

               (A) Stock Appreciation Rights that are Related Rights ("Related
     Stock Appreciation Rights") shall be exercisable only at such time or times
     and to the extent that the Stock Options to which they relate shall be
     exercisable in accordance with the provisions of Section 5 and this Section
     6; provided, however, that any Related Stock Appreciation Right shall not
        --------  -------                                                     
     be exercisable during the first six months of its term, except that this
     additional limitation shall not apply in the event of death or Disability
     of the optionee prior to the expiration of such six-month period.

               (B) Upon the exercise of a Related Stock Appreciation Right, an
     optionee shall be entitled to receive up to, but not more than, an amount
     in cash or that number of shares of Stock (or in some combination of cash
     and shares of Stock) equal in value to the excess of the Fair Market Value
     of one share of Stock as of the date of exercise over the option price per
     share specified in the related Stock Option multiplied by the number of
     shares of Stock in respect of which the Related Stock Appreciation Right is
     being exercised, with the Administrator having the right to determine the
     form of payment.

               (C) Related Stock Appreciation Rights shall be transferable or
     exercisable only when and to the extent that the underlying Stock Option
     would be transferable or exercisable under paragraph (f) of Section 5 of
     the Plan.

               (D) Upon the exercise of a Related Stock Appreciation Right, the
     Stock Option or part thereof to which such Related Stock Appreciation Right
     is related shall be deemed to have been exercised for the purpose of the
     limitation set forth in Section 3 of the Plan on the number of shares of
     Stock to be issued under the Plan, but only to the extent of the number of
     shares issued under the Related Stock Appreciation Right.

               (E) A Related Stock Appreciation Right granted in connection with
     an Incentive Stock Option may be exercised only if and when the Fair Market
     Value of the Stock subject to the Incentive Stock Option exceeds the
     exercise price of such Stock Option.

          (ii) Free Standing Stock Appreciation Rights.

               (A) Stock Appreciation Rights that are Free Standing Rights
     ("Free Standing Stock Appreciation Rights") shall be exercisable at such
     time or times and subject to such terms and conditions as shall be
     determined by the Administrator at or after grant; provided, however, that
                                                        --------  -------      
     Free Standing Stock Appreciation Rights shall not be exercisable

                                      -10-
<PAGE>
 
     during the first six months of its term, except that this limitation shall
     not apply in the event of death or Disability of the recipient of the Free
     Standing Stock Appreciation Right prior to the expiration of such six-month
     period.

               (B) The term of each Free Standing Stock Appreciation Right shall
     be fixed by the Administrator, but no Free Standing Stock Appreciation
     Right shall be exer  cisable more than ten years after the date such right
     is granted.

               (C) Upon the exercise of a Free Standing Stock Appreciation
     Right, a recipient shall be entitled to receive up to, but not more than,
     an amount in cash or that number of shares of Stock (or any combination of
     cash or shares of Stock) equal in value to the excess of the Fair Market
     Value of one share of Stock as of the date of exercise over the price per
     share specified in the Free Standing Stock Appreciation Right (which price
     shall be no less than 100% of the Fair Market Value of the Stock on the
     date of grant) multiplied by the number of shares of Stock with respect to
     which the right is being exercised, with the Administrator having the right
     to determine the form of payment.

               (D) Free Standing Stock Appreciation Rights shall be transferable
     or exercisable subject to the provisions governing the transferability and
     exercisability of Stock Options set forth in paragraphs (c) and (f) of
     Section 5.

               (E) In the event of the termination of an em ployee who has
     received Free Standing Stock Appreciation Rights, such rights shall be
     exercisable to the same extent that a Stock Option would have been
     exercisable in the event of the termination of the optionee.

               (F) For the purpose of the limitation set forth in Section 3 on
     the number of shares to be issued under the Plan, the grant or exercise of
     Free Standing Stock Appreciation Rights shall be deemed to constitute the
     grant or exercise, respectively, of Stock Options with respect to the
     number of shares of Stock with respect to which such Free Standing Stock
     Appreciation Rights were so granted or exercised.

          (iii)  Limited Stock Appreciation Rights.

               (A) Limited Stock Appreciation Rights may only be exercised
     within the 30-day period following a "Change of Control" (as defined in
     Section 10 below), and, with respect to Limited Stock Appreciation Rights
     that are Related Rights ("Related Limited Stock Appreciation Rights"), only
     to the extent that the Stock Options to which they relate shall be
     exercisable in accordance with the provisions of Section 5 and this Section
     6; provided, however, that no Related Limited Stock Appreciation Right
     shall be exercisable during the first six months of its term, except that
     this additional limitation shall not apply in the event of death or
     Disability of the optionee prior to the expiration of such six-month
     period.

               (B) Upon the exercise of a Limited Stock Appreciation Right, the
     recipient shall be entitled to receive an amount in cash equal in value to
     the excess of the

                                      -11-
<PAGE>
 
     "Change of Control Price" (as defined in Section 10) of one share of Stock
     as of the date of exercise over (1) the option price per share specified in
     the related Stock Option, or (2) in the case of a Limited Stock
     Appreciation Right which is a Free Standing Stock Appreciation Right, the
     price per share specified in the Free Standing Stock Appreciation Right,
     such excess to be multiplied by the number of shares in respect of which
     the Limited Stock Appreciation Right shall have been exercised.

Section 7. Deferred Stock and Restricted Stock.

     (a)  General.  Deferred Stock and Restricted Stock awards may be issued to
          -------                                                              
Eligible Employees either alone or in addition to other Awards granted under the
Plan.  The Administrator shall determine the Eligible Employees, and the time or
times at which, grants of Deferred Stock or Restricted Stock awards shall be
made; the number of shares to be awarded; the price, if any, to be paid by the
recipient of Deferred Stock or Restricted Stock awards; the Restricted Period
(as defined in paragraph 7(c) hereof) applicable to Deferred Stock or Restricted
Stock awards; the performance objectives applicable to Deferred Stock or
Restricted Stock awards; the date or dates on which restrictions applicable to
such Deferred Stock or Restricted Stock awards shall lapse during such
Restricted Period; and all other conditions of the Deferred Stock or Restricted
Stock awards. The Administrator may also condition the grant of Deferred Stock
or Restricted Stock awards upon the exercise of Stock Options, or upon such
other criteria as the Administrator may determine, in its sole discretion. The
provisions of Deferred Stock or Restricted Stock awards need not be the same
with respect to each recipient.

     (b) Awards and Certificates.  The prospective recipient of a Deferred Stock
         -----------------------                                                
or Restricted Stock award shall not have any rights with respect to such Award,
unless and until such recipient has executed an agreement evidencing the Award
(a "Deferred Stock Award Agreement" or "Restricted Stock Award Agreement" as
appropriate) and has delivered a fully executed copy thereof to the Company,
within a period of sixty days (or such other period as the Administrator may
specify) after the Award date.

     Except as provided below in this Section 7(b), (i) each Participant who is
awarded Restricted Stock shall be issued a stock certificate in respect of such
shares of Restricted itock; and (ii) such certificate shall be registered in the
name of the Participant, and shall bear an appropriate legend referring to the
terms, conditions, and restrictions applicable to such Award, substantially in

the rate of 8% per year.

Section 8. Amendment and Termination.

     (a) The Board may amend, alter or discontinue the Plan, but no amendment,

prospectively or retroactively, but, subject to Section 3, no such amendment

Section 9.  Unfunded Status of Plan.

     The Plan is intended to constitute an "unfunded" plan for incentive
compensation.  With respect to any payments not yet made to a Participant or

released; and

         (iv)  the value of all outstanding Stock Options, Stock Appreciation

<PAGE>
 
property, as the Administrator may determine, on the basis of the "Change of

determine prior to the Change of Control.

     (b) For purposes of paragraph (a) of this Section 10, a "Change of Control"
shall be deemed to have occurred if:

securities under an employee benefit plan of the Company; or any company owned,
directly or indirectly, by the shareholders of the Company in substantially the
same proportions as their ownership of the Stock of the Company) is or becomes
after the Effective Date the "beneficial owner" (as defined in Rule 13d-3 under
the Exchange Act), directly or indirectly, of securities of the Company (not
including in the securities beneficially owned by such person or any securities
acquired directly from the Company or its affiliates) representing 30% or more
of the combined voting power of the Company's then outstanding securities; or

         (ii)  during any period of two consecutive years (not including any

effect a transaction described in clause (i), (iii) or (iv) of this Section
10(b)) whose election by the Board or nomination for election by the Company's
shareholders was approved by a vote of at least two-thirds (2/3) of the
directors then still in office who either were directors at the beginning of the
period or whose election or nomination for election was previously so approved,
cease for any reason to constitute at least a majority thereof; or

         (iii) the shareholders of the Company approve a merger or consolidation
of the Company with any other corporation, other than (A) a merger or
consolidation which would result in the voting securities of the Company
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity), in combination with the ownership of any trustee or other
fiduciary holding securities under an employee benefit plan of the Company, at
least 75% of the combined voting power of the voting securities of the Company
or such surviving entity outstanding immediately after such merger or
consolidation or (B) a merger or consolidation effected to implement a
recapitalization of the Company (or similar transaction) in which no person
acquires more than 50% of the combined voting power of the Company's then
outstanding securities; or

         (iv)  the shareholders of the Company approve a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially all of the Company's assets.

     (c) For purposes of this Section 10, "Change of Control Price" means the
higher of (i) the highest price per share paid or offered in any transaction
related to a Change of Control of the Company or (ii) the highest price per
share paid in any transaction reported on the exchange or national market system

                                     -15-
<PAGE>
 
period as determined by the Administrator, except that, in the case of Incentive
Stock Options and Stock Appreciation Rights or Limited Stock Appreciation Rights
relating to Incentive Stock Options, such price shall be based only on
transactions reported for the date on which the Administrator decides to cash
out such options.

Section 11. General Provisions.

     (a) The Administrator may require each person purchasing shares pursuant to
a Stock Option to represent to and agree with the Company in writing that such
person is acquiring the shares without a view to distribution thereof.  The
certificates for such shares may include any legend which the Administrator
deems appropriate to reflect any restrictions on transfer.

     All certificates for shares of Stock delivered under the Plan shall be
subject to such stock-transfer orders and other restrictions as the
Administrator may deem advisable under the rules, regulations, and other
requirements of the Commission, any stock exchange upon which the Stock is then
listed, and any applicable Federal or state securities law, and the
Administrator may cause a legend or legends to be placed on any such
certificates to make appropriate reference to such restrictions.

     (b) Nothing contained in the Plan shall prevent the Board from adopting
other or additional compensation arrangements, subject to shareholder approval
if such approval is required; and such arrangements may be either generally
applicable or applicable only in specific cases.

     (c) Each Participant shall, no later than the date as of which the value of
an Award first becomes includable in the gross income of the Participant for
Federal income tax purposes, pay to the Company, or make arrangements
satisfactory to the Administrator regarding payment of, any Federal, state, or
local taxes of any kind required by law to be withheld with respect to the
Award.  The obligations of the Company under the Plan shall be conditional on
the making of such payments or arrangements, and the Company (and, where
applicable, its Subsidiaries) shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
Participant.

     (d) No member of the Board or the Administrator, nor any officer or
employee of the Company acting on behalf of the Board or the Administrator,
shall be personally liable for any action, determination, or interpretation
taken or made in good faith with respect to the Plan, and all members of the
Board or the Administrator and each and any officer or employee of the Company
acting on their behalf shall, to the extent permitted by law, be fully
indemnified and protected by the Company in respect of any such action,
determination or interpretation.

     (e) No Enlargement of Employee Rights.  This Plan is purely voluntary on
the part of the Company, and while the Company hopes to continue it
indefinitely, the continuance of the Plan shall not be deemed to constitute a
contract between the Company and any employee, or to be consideration for or a
condition of the employment of any employee.  Nothing contained in the Plan
shall be deemed to give any employee the right to be retained in the employ of
the Company, its Subsidiaries, or its Parent Corporation to interfere with the
right of the Company, or it Subsidiaries

                                      -16-

to discharge or retire any employee thereof at any time. No employee shall have
any right to or interest in Stock Options, Stock Appreciation Rights or Limited
Stock Appreciation Rights, Restricted Stock, or Deferred Stock, authorized
hereunder prior to the grant of such a Stock Option or other award described
herein to such employee, and upon such grant he or she shall have only such
rights and interests as are expressly provided herein, subject, however, to all
applicable provisions of the Company's Articles of Incorporation, as the same
may be amended from time to time.

Section 12.  Specific Performance.

     The Stock Options granted under this Plan and the Shares issued pursuant to
the exercise of such Stock Options cannot be readily purchased or sold in the
open market, and, for that reason among others, the Company and its shareholders
will be irreparably damaged in the event that this Plan is not specifically
enforced.  In the event of any controversy concerning the right or obligation to
purchase or sell any such Option or Optioned Stock, such right or obligation
shall be enforceable in a court of equity by a decree of a specific performance.
Such remedy shall, however, be cumulative and not exclusive, and shall be in
addition to any other remedy which the parties may have.

Section 13.  Invalid Provision.

     In the event that any provision of this Plan is found to be invalid or
otherwise unenforceable under any applicable law, such invalidity or
unenforceability shall not be construed as rendering any other provisions
contained herein invalid or unenforceable, and all such other provisions shall
be given full force and effect to the same extent as though the invalid
unenforceable provision was not contained herein.

                                     -17-
<PAGE>
 
Section 14.  Applicable Law.

     This Plan shall be governed by and construed in accordance with the laws of
the State of California.

Section 15.  Successors and Assigns.

     This Plan shall be binding on and inure to the benefit of the Company and
the employees to whom an Option is granted hereunder, and such employees' heirs,
executors, administrators, legatees, personal representatives, assignees and
transferees.

Section 16.  Effective Date of Plan.

     The Plan became effective (the "Effective Date") on January 1, 1998.

Section 17.  Term of Plan.

     No Stock Option, Stock Appreciation Right, Limited Stock Appreciation
Right, Deferred Stock or Restricted Stock award shall be granted pursuant to the
Plan on or after the tenth anniversary of the Effective Date, but Awards
theretofore granted may extend beyond that date.

     IN WITNESS WHEREOF, pursuant to the due authorization and adoption of this
plan by the Board on the day and year first above written, the Company has
caused this Plan to be duly executed by its duly authorized officers.

                   [LETTERHEAD OF ALLIANCE BUSINESS CENTERS]

                          LEASE AND SERVICE AGREEMENT

This Agreement is made this 14th day of November, 1997, by and between ALLIANCE 
Business Centers, 2 Wisconsin, Inc., d/b/a ALLIANCE Business Centers ("Lessor")
                                     -------------------------------
having offices known and numbered as Suite 700 (the "Facility") in the building 
located at 2 Wisconsin Circle, Chevy Chase, MD 20815 (the "Building") and 
Affiliate Enterprises, Inc., ("Lessee") a Delaware corporation, with an address 
of 2 Wisconsin Circle, Suite 700, Chevy Chase, MD 20815. The parties for 
themselves, their heirs, legal representatives, successors and assigns, agree as
follows:

     1. Demise and Description of Property.
        -----------------------------------

     a. Lessor leases to Lessee and Lessee leases from Lessor, the             
"Premises" (defined below), being a subpart of Lessor's total leased Facility 
space, for the term and subject to the conditions and covenants hereinafter set 
forth and to all encumbrances, restrictions, zoning laws, regulations or 
statutes affecting the Building, Facility or Premises.

     b. The Premises consists of Facility office space number(s) #725, 
726A/B, 727/728, 729 and 730 as shown in the floor plan annexed hereto. Lessor 
hereby grants Lessee the privilege to use in common with other lessees and 
parties that Lessor may designate certain office amenities located in the 
Facility; the use of all of which are subject to such reasonable rules and 
regulations as Lessor currently has in place and may adopt from time to time. 
The amenities are more particularly described in attached Exhibit "A." "The 
Operating Standards" as presently in place and governing the use of the Premises
and the Facility are attached in Exhibit "B".

     2. Use.
        ----

     a. The Premises shall be used by Lessee solely for Media Development and 
such other normally incident uses and for no other purpose, in strict accordance
with the Operation Standards. Additionally, Lessee shall not offer at the 
Premises any services which Lessor provides to its lessees, including, but not 
limited to those amenities or services described in attached Exhibit "A". In the
event Lessee breaches any provision of this paragraph, Lessor shall be entitled 
to exercise any rights or remedies available to the Lessor pursuant to this 
Agreement together with such other rights and remedies as the Lessor may 
otherwise have and choose to exercise.

     b. Lessee shall not make nor permit to be made any use of the Premises 
which would violate any of the terms of this Agreement or which, directly or 
indirectly, is forbidden by statute, ordinance or government regulations, which 
may be dangerous to life, limb or property, which may invalidate or increase the
premium of any policy of insurance carried on the Building or on the Facility, 
which will suffer or permit the Premises to be used in any manner or anything to
be brought into or kept there which, in the sole judgment of Lessor, shall in 
any way impair or tend to impair the high quality character, reputation or 
appearance of the Building or the Facility, or which may or tend to impair or 
interfere with any services performed by Lessor for Lessee or for others.

     3. Term.
        -----

     a. The term of this Agreement shall be for a period of twelve months, 
commencing 9:00 a.m. on the 1st day of January, 1998, and ending 5:00 p.m. on 
the 31st day of December, 1998, unless renewed as provided in paragraph "3(b)" 
herein.

     b. Upon the ending term date set forth herein or any extension thereof, the
Agreement shall be extended for the same period of time as the initial term and 
upon the same terms and conditions as herein contained except for the amount of 
base rental charges, which shall each be increased by ten percent (10%), unless 
either party notifies the other in writing by certified or registered mail, 
return receipt requested, or delivered by hand that the Agreement shall not be 
extended within the period hereinafter specified or automatically renewed. If 
Lessee has less than three offices, such notice shall be given at least 60 days 
prior to the expiration date of this Agreement. If Lessee has three or more 
offices, such notice shall be given at least 90 days prior to the expiration 
date of this Agreement.

     c. In the event the entire Premises or the Facility are damaged, destroyed 
or taken by eminent domain or acquired by private purchase in lieu of eminent 
domain so as to render the Premises fully untenantable and unrestorable in 
Lessor's sole judgment, then within 90 days thereafter by written notice to the 
other party, either party shall be able to terminate this Agreement, which will 
terminate as of the date thereof.

     4. Rent.
        -----

     a. For and during the term of this Agreement, Lessee shall pay Lessor as 
rent for the Premises a annual total rental of $101,304.00, payable in equal 
monthly installments of $8442.00, each payable in advance of the first day of 
each calendar month after the commencement of the term, or a daily prorated 
amount for any partial calendar month during the term. If any payment of rent or
other charges due under this Agreement is not received within five (5) calendar 
days after its due date, the Lessee will also pay, as additional rent, a late 
payment charge which shall be an amount equal to 10% of any amount owed to 
Lessor or $50 whichever is greater.

b.      It is additionally specifically covenanted and agreed that the financial
terms of this Agreement are strictly confidential and Lessee agrees not to 
knowingly or willfully divulge this information to or any other Lessee or 
potential Lessee of Lessor. Any such disclosure by the Lessee of the financial 
terms of this Agreement as set forth herein above, shall constitute a material 
breach of this Lease.

        c. The first such payment of rental as well as the payment of the 
Deposit as set forth in below shall be paid by Lessee simultaneously with 
execution of this Agreement. Should the Lessee fail to make such payment prior 
to the commencement of the term of


                                       1      /s/RJW Initials    /s/RJW Initials
                                              -------            -------
                                                       /s/ LS
                                                       ------
<PAGE>
 
     c.   The first such payment of rental as well as the payment of the Deposit
as set forth in below shall be paid by Lessee simultaneously with execution of 
this Agreement. Should the Lessee fail to make such payment prior to the 
commencement of the term of this Agreement, then, at Lessor's sole option, the 
Agreement shall be null and void and of no further effect.
     d.   The rental payable during the term of this Agreement shall be 
increased on the first day of the month following notification of any rental 
increase (however designated) which the Lessor might receive from the Lessor's 
over-landlord ("Building"). The term "direct expenses" as used herein shall 
refer to the same items and costs as are used by the Building in its 
determination of expenses and costs passed on to Lessor. Lessor shall
immediately notify Lessee in writing of any such increase, and shall bill Lessee
for its pro rata share thereof, which bill Lessee shall pay promptly upon such
notification for each and every month thereafter for the balance of the term.
     e. Rent charges are based on the value of the rental Premises and services
to be used by one person(s) per office and two persons for Office #730 only. If
more than said number of person(s) habitually use the Premises or services, the
Fixed Monthly Rental Charges will be increased by a factor of $100 for each
additional person who habitually uses the Premises.
     f.   If a Lessee check is returned for any reason, Lessee will pay an 
additional charge of $100.00 per returned check and, for the purpose of 
considering default and/or late charges, it will be as if the payment 
represented by the returned check had never been made.

     5.   Security Deposit.
          ----------------

     a.   Lessee shall deposit with Lessor $16,884.00, or the equivalent of two 
months rent, in good or certified funds with a domestic bank, as a non-interest 
bearing security deposit. Lessor may use the security deposit to cure any 
default of Lessee under this Agreement, restore the Premises including any and 
all furniture, fixtures and equipment provided by Lessor and vendors at the 
Premises to their original condition and configuration, reasonable wear and tear
excepted, to pay for repairs to any damage to the Premises, Executive Suite or 
Building, caused by Lessee or Lessee's guests, to pay any rent or other charges 
which Lessee owes Lessor at or prior to the expiration of this Agreement, and to
reimburse Lessor for costs or expenses arising from any other obligation of 
Lessee which Lessee has failed to perform. If Lessor transfers control or 
ownership of the Premises and Lessor transfers the security deposit to such 
purchaser, Lessee will look solely to the new Lessor for the return of the 
security deposit, and the Lessor named in this Agreement shall be released from 
all liability for the return of the security deposit.
     b.   The security deposit (less any sums used by Lessor in accordance with 
the terms and conditions of this Agreement) will be returned within sixty (60) 
days after the termination of any services rendered or expiration of the term 
hereof. The security deposit shall not under any circumstance be applied in lieu
of be the final payment(s) of Fixed Monthly Rental charges or service charges
under this Agreement.
     c.   In the event that, by reason of the Lessee's default in its 
obligations pursuant to this Agreement or otherwise, including but not limited 
to the payment of the Fixed Monthly Rental Charge, any amounts due by reason of 
the Lessee's use of additional services hereto and/or by reason of the Lessee's 
use of telephone services as supplied pursuant to this Agreement, Lessor shall 
be entitled to apply any of the security deposited pursuant to this Agreement to
any outstanding sums due or owing to the Lessor, and Lessor shall have the right
to charge the Lessee, as additional rent, such sums as are necessary to 
replenish any and all amounts applied so as to cause the security to be returned
to its entire amount. The failure to pay such amounts as are necessary to 
replenish the security shall be considered a breach of this Agreement and shall 
entitle the Lessor to exercise any of its rights pursuant to this Agreement or 
otherwise.

      6.   Delivery of Possession.
           ----------------------

      If, for any reason whatsoever, Lessor cannot deliver possession of the 
Premises to Lessee at the commencement of the term, this Agreement shall not be 
void nor voidable nor shall Lessor be liable to Lessee for any loss or damage 
resulting therefrom, but there shall be an abatement of rent for the period 
between the stated term commencement and the time when Lessor does deliver 
possession of the Premises.

     7.   Services.
          --------

     a.   So long as Lessee is not in default hereunder, Lessor shall make 
available certain amenities to Lessee as more particularly described in Exhibit 
"A." Such services shall be offered to Lessee, in conjunction with such services
being offered by Lessor to its other lessees, without charge for the reasonable 
use of the same.
     b.   In addition, provided Lessee is not in default hereunder and provided 
the cost thereof does not exceed the Security Deposit, Lessor shall make 
available to Lessee certain other services the cost of which shall be billed to 
the Lessee as additional rent and the payment of which shall be subject to the 
same terms and conditions as those governing the payment of the Fixed Monthly 
Rental Charge herein regardless of when such charges are billed to the Lessee.

     8.   Telephone Services.
          ------------------

     a.   Provided Lessee is not in default of any of the terms, covenants, 
conditions or provisions of this Agreement, Lessor will make available to 
Lessee, a telecommunications package which will consist of some combination of 
telephone equipment, numbers, lines, conference calling, voice mail, local, long
distance and international service, and directory listing. All components of the
telecommunications package including any telephone numbers used by Lessee will 
remain at all times the property of Lessor and Lessee will acquire no rights in 
the components beyond the term specified by Lessor.
     b.   Upon Lessee's written request, Lessee shall be entitled to appoint 
Lessor as its exclusive agent for the sole purpose of procuring and arranging

Lessor or from the conduct of Lessee's business, or from any activity, work, or 
thing done in the Premises or common areas by Lessee or Lessee's agents,

damage to person or property caused by any person except for such loss or damage

(c)  Relationship to forecasts:  Skysite acknowledges that the Commitment and 
the Quarterly Minimums will be used by AMSC for its own capacity and traffic 
planning requirements, and that therefore the Quarterly Minimums shall not be 
modified or deferred for any reason, including, without limitation, the

its customers and potential customers on a "private label" basis.  Skysite shall
not use AMSC's name, brand names, trademarks or servicemarks without AMSC's

customer's use of the Service, including, without limitation, all required MT's.

(d)  Forecasts:  Skysite shall provide AMSC with written forecasts of Skysite's
     ---------
requirements for Communications Time.  Five year forecasts shall be provided 
semi-annually, beginning upon execution of this Agreement, and shall identify
Skysite's anticipated usage on a quarterly basis for the first two years and on
a semi-annual basis for the last three years.  Skysite shall provide AMSC upon

with the interconnection facilities which Skysite may provide as set forth 
herein.

     (3)  AMSC right of access:  For the protection of AMSC's network, services,
          --------------------
facilities and personnel, Skysite hereby grants AMSC the right at any time, and
from time to time, upon reasonable prior notice except in the case of an
emergency, to inspect all equipment and communications facilities or services
used by Skysite or its customers for compliance with FCC regulations, this
Agreement, and AMSC's emission requirements, protocol standards and other
technical requirements.

foregoing, call detail information will be limited to the origin, destination,
and duration of calls, and no taxes, other assessments, or call rating will be
applied.

     (2)  AMSC will provide call detail records to Skysite on media and in a 
format agreed upon by the parties, provided, however, that if the parties agree 
on a medium and format substantially different from the media and format in

customers, AMSC reserves the right to charge Skysite for

                                     - 4 -
<PAGE>
 
providing call detail records in such other agreed upon medium and format, based
on AMSC's costs of preparation and delivery, including but not limited to any 
hardware/software modifications required to AMSC's facilities.  AMSC will advise
Skysite in writing of any such costs and shall render an invoice, which will be 
payable as described in section 2.5 of this Agreement.

     (3)  AMSC will use reasonable efforts, but shall not be obligated, to 
develop a means by which Skysite may have electronic access to the call detail

     --------------------
Skysite requesting deactivation of a MT, promptly arrange for such deactivation,
but Skysite shall be liable for all charges for calls made from or directed to 
any MT activated at Skysite's request until the end of the business day next 
succeeding the date on which AMSC receives notice from Skysite to deactivate 
such MT.  The parties will agree in writing on the activation/deactivation 
procedure for MT's on or before the Commencement Date; this procedure will 
include a provision for emergency deactivation in the event of fraudulent usage 
of a MT or MT's.

CGS, and AMSC shall have not liability for any costs related thereto nor any 
responsibility for the installation, maintenance or operation thereof; and

     (2)  Calls will be deemed "completed," for purposes of section 2.1(c) of 
this Agreement, when delivered to Skysite's switch, and Skysite shall be solely 
responsible for the delivery and completion of calls to the called party; and

     (3)  The rates for Service will be reduced as described in section 
2.1(a)(2) of this Agreement if Skysite elects to provide its own facilities 
under this paragraph (a).

(b)  Subsequent to an election under paragraph (a) of this section 1.5, Skysite
may, by ninety (90) days' written notice, but no more often than annually, elect
to have AMSC resume provision and maintenance of interconnection facilities in 
accordance with this section 1.5.

(c)  Upon receipt by AMSC of an election notice under paragraph (a) or (b) of 
this section 1.5, AMSC and Skysite diligently shall endeavor to transfer Call 
Transport Termination from or to Skysite's facilities and equipment, as the case
may be, in accordance with a schedule mutually

                                     - 5 -
<PAGE>
 
agreed upon by the parties.  Beginning with the first day after completion of 
such transfer, Skysite shall be billed at the appropriate rates for Service, as 
described in section 2.1(a) of this Agreement.  Skysite shall be responsible 
for, and promptly shall pay upon receipt of an invoice from AMSC, all costs and 
charges reasonably incurred and documented by AMSC in completing such transfer.

1.6   FRAUD PREVENTION.
      ----------------

(a)   The Service is provided subject to the condition that there will be no 
abuse or fraudulent use thereof.  Abuse and fraudulent use include, but are not 
limited to, the following:

attempting to obtain, interrupt, access, alter, or destroy, any files, programs,
information and/or use of the Service of another AMSC customer or user by

in no event more than 24 hours after receipt of notice from AMSC, in the event 
of their abuse or fraudulent use of or access to the Service or any other AMSC 
facility.

1.7   GENERAL.
      -------

(a)   Contacts and coordination:  The parties shall appoint and identify to
      -------------------------
one another in writing such contacts as are reasonably necessary for
coordination of matters relating to technical, administrative, and billing

relieve the generating party of responsibility for legal compliance with the 
advertisement. Materials previously approved by a party shall not be subject to 
repeated approvals before subsequent use.

     (2) Except as provided in section 1.3(a) of this Agreement, Skysite shall 
have no right, title or interest in or to AMSC's name, logo, trademarks or other
trade designations, and Skysite shall not make any use thereof without the 
express prior written permission of AMSC.

(c)  Ethical responsibilities of the parties: AMSC and Skysite shall each 
     ---------------------------------------
refrain from doing anything that would tend to discredit, dishonor, reflect 
adversely upon, or in any manner injure the reputation of the other or adversely
affect the other, or, in the case of AMSC, adversely affect AMSC's status as a 
licensed common carrier, except that a party's enforcement of its rights and 
performance of its duties and obligations contained herein shall not be deemed a
violation of the provisions of this paragraph (c). Each party shall be governed 
in all its dealings under this Agreement by the highest standards of honesty, 
integrity, and fair dealing.

     (d)  Confidentiality: The Reciprocal Nondisclosure Agreement between the
          ---------------
parties, entered into contemporaneously with this Agreement and shown as Exhibit

Notwithstanding the foregoing, the 11/3/95 Agreement shall apply to all
information exchanged by the parties up to the date of execution of this
Agreement and the Nondisclosure Agreement shown in Exhibit 2. Without
limitation, the parties agree that their respective customer information,
including traffic and traffic projections, forecasts, customer lists, and other
customer account information (collectively, "Customer Information") is deemed to

(a)  No alteration or modification: User Equipment may not be altered or 
     -----------------------------
modified without the advance written approval of the manufacturer and 
certification by AMSC that altered or modified User Equipment is accepted for
use with the Service and AMSC's MSS network generally. Alteration or
modification of User Equipment may void the manufacturer's warranty, and AMSC
reserves the right to deny or terminate Service to altered or modified User
Equipment and shall have no liability whatever to Skysite or Skysite's customers
for any loss or damage caused by unauthorized altered or modified User Equipment
or by the termination of Service to such User Equipment.

(b)  Installation, warranty, and maintenance: Skysite shall be responsible for
     ---------------------------------------

be on a prepaid basis.

     (1)  Skysite shall place orders for User Equipment in accordance with 
AMSC's then-current policies and procedures, as provided to Skysite from time to

discounts or special promotions for which Skysite is eligible, and are subject
to change upon written notice from AMSC. Volume discounts, if offered, will be
available only for units ordered at one time, on the same sales order number.
Separate orders, even if placed on the same day, may not be aggregated to be
eligible for volume discount pricing.

     (3)  Skysite acknowledges and agrees that AMSC is neither the manufacturer 
nor the warrantor of User Equipment. Skysite agrees to look solely to the User 
Equipment manufacturer of the manufacturer's authorized service agent for 
warranty or maintenance service.

     (4)  Unless otherwise agreed in writing by AMSC and Skysite, User Equipment
will not be pre-commmissioned before shipment. AMSC reserves the right to assess

     ----------------------------------
the provisions of paragraph (c) of this section 1.8, Skysite may at its option

                                  ARTICLE TWO
                          RATES, BILLING, AND PAYMENT
                       ---------------------------------

2.1  RATES AND CHARGES.
     -----------------

(a)  Rates:  Rates and charges for the Service shall be as set forth in Exhibit 
     ----- 
3, which is attached to and made a part of this Agreement.

     (1)  The rates shown in Exhibit 3 are based on the volume of the 
Commitment. Skysite may at its option, upon 60 days' written notice to AMSC, 
elect to increase the Commitment, and in consideration of such increase, AMSC 
will make available to Skysite AMSC's then-current rates for the volume elected 
by Skysite, or such other rates as the parties may agree upon in writing. The 
increased Commitment shall be (i) effective for the remainder of the 
then-current Term of this Agreement and (ii) subject to the provisions of
section 1.2 of this Agreement

                                     - 8 -
<PAGE>
 
     (2)   The per minute prices shown in Exhibit 3 will be reduced by Seven
Cents ($.07) per minute - if Skysite performs Call Transport Termination as
described in section 1.6(c) of this Agreement.

     (3)   AMSC covenants that Skysite shall at all times under this Agreement
receive a discount of no less than Twenty Five Percent (25%) off of AMSC's then-
current "base retail rates" for On-Demand Service, including Skycell Satellite
Dispatch Service, but excluding Fixed Site service.

     (i)   If and when AMSC's base retail rates for On-Demand Service (other
     than for Fixed Site service) change, AMSC shall promptly notify Skysite and
     modify this Agreement in writing as necessary to provide Skysite with at
     least a Twenty Five Percent (25%) discount off of AMSC's rates for On-
     Demand Service, except for the rates for Fixed Site service.

     (ii)  For purposes of this Agreement, "base retail rates" are the rates
     charged by AMSC for the smallest volume or unit and/or the shortest term
     duration in which AMSC prices the service and sells it on a regular basis
     to unaffiliated entities, without discount for volume, duration of term, or
     other discount or promotion. Skysite acknowledges and agrees that AMSC may
     grant volume- or term-based or promotional discounts to its other customers
     for those services and that AMSC shall not be obligated to guarantee
     Skysite a Twenty Five Percent (25%) discount off of volume- or term-based
     or promotional discounts.

     (iii) Notwithstanding the foregoing, AMSC agrees that if, in any quarter,
     Skysite's total purchases of On-Demand Service and Channels exceed the
     applicable Quarterly Minimum for that quarter by at least 50%, AMSC will
     sell User Equipment to Skysite at AMSC's cost for the subsequent quarter.

(b)  Skycell Satellite Dispatch Service Plus rates: Skysite currently receives a
     ---------------------------------------------
thirty percent (30%) discount off of AMSC's then-current retail rates for
Skycell Satellite Dispatch Service. Current Skycell Satellite Dispatch Service
rates are shown in the attachment to Exhibit 2 to this Agreement. AMSC will not
increase Skysite's rates for Skycell Satellite Dispatch to reflect the 25%
discount described in paragraph (a)(3) of this section 2.1, but if AMSC lowers
its base retail rates for Skycell Satellite Dispatch Service, Skysite's rates
will be lowered only to the 25% discount level. Notwithstanding the foregoing,
the rates for "Voice Airtime per Minute" as shown on Exhibit 2 shall not be
available to Skysite, and the rates for voice airtime shall be as set forth in
Exhibit 2 to the Agreement. Skysite's resale of Skycell Satellite Dispatch
Service will be subject to the provisions of section 1.3(a) of this Agreement.

(c)  Calculation of charges:
     ----------------------

     (1)   All charges for Communications Time shall be based on actual minutes
used (rounded up to the next whole minute) and will be applied to calls both to
and from each MT.

                                     - 9 -
<PAGE>
 
If AMSC changes its billing policy and calculates Communications Time in less
than whole-minute increments, Skysite billing calculations shall be changed
accordingly.

     (2)  AMSC will bill Skysite for completed calls only, subject to the
provisions of section 1.5(a)(2) of this Agreement. A "completed call" is one
that is answered by the called party or, if unanswered, rings for more than 70
seconds.

     (3)  The rates described in this section 2.1 assume Call Transport
Termination by AMSC and within the 48 continental United States ("CONUS").
Unless Skysite is performing Call Transport Termination AMSC shall add a charge
for long distance connections for all Call Transport Termination outside of
CONUS. International long distance charges are passed through at AMSC's cost.

2.2  QUARTERLY RECONCILIATION.
     ------------------------

AMSC shall deliver to Skysite a reconciliation on a quarterly basis, comparing
Skysite's actual Cumulative Purchases during the previous quarter to the
applicable Cumulative Quarterly Minimum for that period.

2.3  BILLING OF CHARGES
     ------------------

AMSC shall bill Skysite for all Service rates and charges, including On-Demand
Service and Channels, and for User Equipment purchased by Skysite from AMSC
under this Agreement as set forth in this section 2.3

(a)  Monthly billing: Fixed, recurring charges, including, but not limited to,
     ---------------
Access Fees and any deactivation or reactivation fees, and any other basic
monthly fees for On-Demand Service will be billed in advance. Usage and call
delivery charges will be billed in arrears in the month following the month in
which they are incurred.

     (1)  AMSC will issue to Skysite a monthly invoice on or before the 7th day
of each month. Skysite shall make Weekly Payments, as described in section 2.5,
defined in section 2.5(b) of this Agreement, in respect of such invoices.

     (2)  For purposes of computing partial month charges for access fees, each
day is considered to be 1/30 (one-thirtieth) of a month. A first invoice may
contain charges from a previous billing period for service provided from the
date of installation through the current invoice period.

(b)  Quarterly billing: AMSC shall invoice Skysite, and Skysite shall pay AMSC,
     -----------------
quarterly in advance for Channel(s). AMSC will invoice Skysite for new Channels
upon receipt of Skysite's order. An initial Channel invoice will be prorated on
a daily basis for the remainder of the quarter in which the Channel is
activated.

                                    - 10 -
<PAGE>
 
(c)  Reconciliation invoice: If Skysite's Cumulative Purchases are less than the
     ----------------------
applicable Cumulative Quarterly Minimum, AMSC will add to the next monthly
invoice an amount equal to the difference between Cumulative Purchases and the
applicable Cumulative Quarterly Minimum, and Skysite shall pay such invoice as
provided in section 2.5 of this Agreement. Such reconciliation and invoice
shall, absent manifest error, be deemed conclusively to establish such Actual
Usage.

(d)  User Equipment: User Equipment must be paid for prior to shipment,
     --------------
separately from charges for On-Demand Service and Channels.

2.4  TAXES.
     -----

All rates set forth in this Agreement are exclusive of Applicable Taxes. For
purposes of this Agreement, "Applicable Taxes" are taxes, assessments,
surcharges, levies, or similar items assessed by a governmental body. Skysite is
liable for, and shall indemnify AMSC from and against, all Applicable Taxes
which may be passed directly through to Skysite or its customers, and all
Applicable Taxes properly chargeable to Skysite or its customers with respect to
AMSC's provision of the Service to Skysite or relating to Skysite's use, resale,
or lease of the Service or MT's to Skysite's customers or others, and/or any
penalty and interest thereon if assessed by the applicable governmental body.
AMSC will invoice Skysite for such penalties and interest, and Skysite shall pay
such invoices in accordance with the provisions of section 2.5(a) and (b) of
this Agreement.

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

(a)  Payment method: Skysite shall make all payments under this Agreement for

(d)  Post Cure Period payments: For the month of May 1998 through the end of the
     -------------------------
Term ("Post Cure Period"), Skysite shall, subject to the provisions of section
2.6(a) of this Agreement, prepay On-Demand Service in installments, as follows:

     (1)  AMSC and Skysite will calculate the amount to be paid each month by

invoice ("Estimated Invoice"). During the month before the month in which the
invoice will be rendered, Skysite will make Weekly Payments in equal
installments of the Estimated Invoice, as illustrated in Exhibit 5 to this
Agreement.

     (2)  If the actual invoice for any month, including as appropriate, amounts
invoiced as a Reconciliation Invoice, as described in section 2.3(c) of this

decreased based on Skysite's actual monthly On-Demand purchases.

    (4)   If Skysite provides a Security Deposit as provided in section 2.6(a)
of this Agreement, AMSC will invoice Skysite monthly for actual usage, and
Skysite shall make four (4) Weekly Payments in equal portions of the invoiced
amounts begining the second Friday of each month.

(e)   Failure to make Weekly Payments: If Skysite fails to make Weekly Payments
      -------------------------------
as prescribed by paragraphs (c) and (d) of this section 2.5, the provisions of
section 4.1(a) of this Agreement shall apply.

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

Skysite shall be required to pay a late charge, equal to one and one-half
percent (1 1/2%) per month on the unpaid amount of such invoice and any other
outstanding balance. The late charge shall be calculated from the due date of
the invoice until payment is received. Notwithstanding the foregoing, and
without prejudice to its right to assess late charges on future amounts which

costs of collection incurred by AMSC, including collection fees, reasonable
attorney's fees, and litigation expenses. AMSC will invoice Skysite for such
charges, and Skysite shall pay such invoice in accordance with the provisions
of paragraphs (a) and (b) of this section.

2.6   CREDITWORTHINESS
      ----------------

(a)   Security Deposit: In lieu of prepaying for On-Demand Services in

                                    - 13 -

<PAGE>
 
     (1)  Based on AMSC's assessment of Skysite's creditworthiness, financial 
standing, and payment history, the Security Deposit would be in an amount equal 
to one (1) month's average billings under this Agreement, calculated based on 
the average of the billings for the calendar months preceding the delivery of 
the Security Deposit. Skysite may at its option apply its prepayments to the 
security deposit.

     (2)  AMSC reserves the right, based on increases in Skysite's average 
monthly billings, to request that the Security Deposit be increased to an amount
equal to one month's average billings, calculated based on the average of the 
billings for the three (3) month period immediately preceding AMSC's request for
an increase and Skysite will either increase the Security Deposit upon such 
request or resume prepayments as described in section 2.5(d) of this Agreement.

     (3)  AMSC will retain the Security Deposit, if provided, as security for 
Skysite's prompt payment of amounts due under this Agreement and reserves the 
right to apply the Security Deposit against any amounts due under this Agreement

In such an event, AMSC reserves the right to require Skysite to, and Skysite 
promptly shall, restore the Security Deposit to its original amount or increase 
the amount of the Security Deposit.

(b)  AMSC will release the Stock Escrow Agreement dated April 9, 1996, among 
Skysite, AMSC, and West America Securities on May 2, 1998, provided that all 
payments have been made during the Cure Period as required by section 2.5 of 
this Agreement.

2.7  RECORDKEEPING AND AUDIT.
     -----------------------

(a)  Maintenance of records: Each party shall, directly or through  a third 
     ----------------------
party service bureau, create and maintain full, complete and accurate records of
business conducted pursuant to this Agreement, including but not limited to data
relating to customer activations, deposits, call placement and delivery,
invoices, payments, and Service credits. Records shall be retained for the
longer of two (2) years, or as long as required by applicable law.

(b)  Request for audit: If the parties have a bona fide dispute as to the 
     -----------------
amounts paid or unpaid, owed and owing hereunder, each party reserves the right 
to request, no more frequently than annually, an audit of the records maintained

(c)  Performance of audit: Such an audit shall be performed by an independent 
     --------------------
accounting firm agreed upon by AMSC and Skysite and shall be subject to the 
audited party's standard security and confidentiality procedures. To the extent

audit and not to the underlying records which are the subject of the audit.

(d)  Cost of audit: The party requesting the audit under this section 2.7 shall 
     -------------

                                USE OF SERVICE
                              ------------------

31.  REGULATORY MATTERS.
     ------------------

(a)  Lawful purposes:  Skysite and its customers shall utilize the Service only 
     ---------------
for lawful purposes and in compliance with all applicable rules, policies and 
regulations of the FCC and those of any other Federal, State or local 
governmental bodies.

(b)  Relationship to FCC:  All MSS provided by AMSC, including the Service as 
     -------------------
provided under this Agreement, is subject to the continuing approval of the 
FCC. Skysite hereby consents to the filing of this Agreement with the FCC if 
required by applicable law and regulation. AMSC shall advise Skysite in advance 
of such a filing.

(c)  Allocation of capacity:  Skysite acknowledges and agrees that (1) MSS, 
     ----------------------
including the Service, capacity is finite and will be made available to AMSC's 
customers, including Skysite and its customers, on a first-come, fist-served 
basis, subject to the availability of MSAT capacity; and (2) AMSC reserves the 
right, in its sole discretion, to allocate MSAT satellite capacity among all of 
its services, including the Service provided under this Agreement. AMSC shall 
determine in its sole discretion how and whether to obtain additional satellite
capacity, whether for restoral or for the expansion of AMSC's services.

3.2  PREEMPTION, INTERRUPTION, OR SUSPENSION OF SERVICE.
     --------------------------------------------------

(a)  The Service may be pre-empted, interrupted or suspended due to conditions 
or for reasons beyond Supplier's control ("Emergency Pre-emption"), including 
but not limited to maintenance requirements or emergency conditions experienced 
by AMSC; to protect AMSC's personnel, facilities, or services; to provide 
priority and pre-emptive access to Supplier's satellite system by the Federal 
Aviation Administration, U.S. Coast Guard, or other governmental agency as 
required under AMSC's FCC license, or to provide responsive emergency support to
government agencies during any natural or man-made disasters or otherwise as 
required by law (collectively "Government Priority Access").

(b)  In the event of Emergency Pre-emption, AMSC will notify Skysite as soon as 
practicable and shall use its best efforts to restore Skysite's Service in 
accordance with AMSC's priority restoral policies. Under AMSC's policies, users 
of dedicated satellite channels receive the highest priority except for 
Governmental Priority Access. Dedicated channels will not otherwise be 
pre-empted or diverted for use by other customers.

                                    - 15 -
<PAGE>
 
(c)  Restoral of Service in the event of a short term outage will be performed 
in accordance with Supplier's policies and procedures as quickly as practicable 
consistent with maintaining the integrity of the Service and AMSC's mobile 
satellite system. Skysite acknowledges that AMSC's system does not generally 
provide for selective or successive restoral of channels, or of individual 
customers.

(d)  In the event of an outage affecting AMSC's entire mobile satellite system 
("Catastrophic Outage"), dedicated channels will, to the extent consistent with 
the orderly restoration of service generally, be the first to be restored, 
either on AMSC's satellite or by transfer to TMI's satellite (if and to the 
extent capacity is provided on such satellite pursuant to agreement between AMSC
and TMI). Skysite acknowledges that on-demand services are not subject to 
restoral on the same terms as dedicated channels.

3.3  SERVICE CREDITS:
     ---------------

(a)  AMSC will grant to Skysite a service credit in the event of Service 
outages, including outages caused by Emergency Preemption, as set forth in this 
section 3.3. No service credit will be granted where the Service is interrupted 
or unavailable due to the negligence of Skysite or to the failure of facilities 
and equipment provided by Skysite or its other communications providers.

     (1)  Skysite shall accrue credit for future Service in an amount equal to 
the actual period of time for which the Service is completely unavailable for a 
period of one hour or more. AMSC shall maintain a log of all such service 
credits. If Skysite has not used the full amount of the Commitment by the end of
the Term, the Term shall be extended for an amount of time equal to the 
aggregate amount of service credits due to Skysite as shown in the log. 
Otherwise, the service credit shall expire at the end of the Term, and no 
monetary or other credit compensation shall be given to Skysite in respect 
thereof.

     (2)  Where the Service remains available but is modified or restricted so 
as to affect adversely the Service for a period of 24 hours or more, a credit 
allowance will be given at the discretion of AMSC, based on the extent and 
duration of such modification or restriction.

     (3)  No credit allowance will be given where the Service is preempted, 
interrupted, suspended, modified, or restricted for a period of less than one 
(1) hour.

     (4)  AMSC shall issue Customer a credit equal to 1/30th of the amount of 
any Access Fees paid in a month in respect of each full day (i.e. from 12:00 
a.m. to 11:59 p.m.) that the Service is unavailable. 

     (5)  In addition, if Skysite provides a credit to an End User in respect of
an active call which is dropped as a result of any unavailability of the 
Service, AMSC shall issue a credit to Skysite equal to the lesser of (i) the 
amount of credit issued to such End User by Skysite and (ii) the amount billed 
to Skysite by AMSC for the last minute of such call. Skysite shall provide AMSC 
upon request with documentation of credits granted to its End Users.

       Distributor's responsibility to notify Westinghouse of any orders for
       which acknowledgment is not received within the aforementioned five (5)
       business day period. Products shall be purchased solely upon the terms
       and conditions contained in this Agreement. Any different terms and
       conditions in Distributor's purchase order forms or other writings shall
       not be binding on the parties.

    applicable to, measured by, or imposed upon, or with respect to the Products
    covered by this Agreement, the property, its sale, its value or its use or
    any service performed in connection therewith. Such taxes are for the
    account of Distributor and the Distributor agrees to pay or reimburse any
    such taxes which Westinghouse or its contractors or suppliers are required
    to pay.

(d) Shipment. Delivery will be F.O.B. Westinghouse's shipping point. All
    ---------
    shipments hereunder will reference Distributor's Order number on the packing
    slip. Unless otherwise instructed by Distributor Westinghouse will select
    the carrier and ship the Products to Distributor. Alternatively, Distributor
    may arrange for its representative to receive the Products at a designated
    facility. Title and risk of loss for Products purchased under this Agreement
    shall pass to Distributor upon delivery to the carrier at the Westinghouse
    shipping point.

(e) Delivery Dates. Delivery dates as set forth in any purchase order or
    ---------------
    confirmation thereof are only estimates. Westinghouse shall not be liable to
    Distributor, and Distributor shall not be relieved of its obligation to
    accept any shipment, by virtue of any delay in or failure of delivery.

    ------------------
    identified in exhibit F hereto, which must be in the United States.

    Westinghouse, may, in its sole discretion, deem appropriate.

(h) Acceptance of Purchase Orders. All purchase orders for Products are subject
    ------------------------------
    to acceptance by Westinghouse, and Westinghouse shall have the right at any
    time, in its sole discretion, to reject or to decline to fill any purchase
    order, either in whole or in part.

(i) Payment. Payment shall be in accordance with the terms of Westinghouse
    --------
    invoice and payment shall be made in U.S. dollars by wire transfer, check or
    other instrument acceptable to Westinghouse. Any invoiced amount which is
    not paid when due will bear interest at the rate of eighteen percent (18%)
    per annum, to the extent permitted by applicable law. All exchange, interest
    banking, collection, or other charges shall be at the sole expense of
    Distributor.

(j) Warrant. Westinghouse provides end users a written limited warranty
    --------
    specifically applicable to the Series 1000 Mobile Telephone System, the
    current version of which is attached hereto as Exhibit E. Westinghouse may,
    at its sole option, change the duration and terms of such warrant at any
    time or times. Such warranty shall establish exclusively the extent of
    Westinghouse's responsibility for any failure of or defect in the Products.

          WESTINGHOUSE MAKES NO WARRANTIES WITH RESPECT TO THE PRODUCTS OF ANY
          KIND WHATSOEVER, EXPRESS OR IMPLIED, EXCEPT AS SPECIFICALLY PROVIDED
          IN WESTINGHOUSE'S WRITTEN LIMITED WARRANTY AS IN EFFECT FROM TIME TO
          TIME. THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR ANY
          PARTICULAR PURPOSE ARE HEREBY DISCLAIMED AND EXCLUDED. WESTINGHOUSE
          SHALL NOT BE LIABLE TO DISTRIBUTOR OR ANY THIRD PARTIES FOR ANY
          SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES.

     (k)  To the extent Westinghouse is deemed to have any liability hereunder,
          no such liability shall ever be in excess of the value of the goods
          sold hereunder, or one million US dollars, whichever is less.

     (l)  Liability Insurance. Westinghouse confirms that product liability
          --------------------
          insurance written by an insurance company licensed to do business in
          the United States and Canada in the amount of not less than $1,000,000
          combined single limit is maintained with respect to the Products.
          Except to the extent of such product liability coverage, Distributor
          shall have no claim or right against Westinghouse with respect to any
          suits or claims against Distributor by any third persons resulting
          from the occurrence of an event within the scope of coverage of such
          insurance (without reference to the dollar amount of coverage), and
          Westinghouse shall bear no responsibility or liability to Distributor
          with respect to any such suits or claims by any third parties or any
          liabilities, losses, expenses or damages incurred or suffered by
          Distributor as a result thereof.

5.   Termination. This Agreement shall continue in effect unless and until
     ------------
     terminated by Westinghouse or the Distributor for any reason or no reason
     upon thirty (30) days prior written notice. Such written notice of
     termination shall be delivered or sent by registered mail to the other 
     party at the address set forth in Paragraph 15 below.
 
     (a)  all orders in effect on the date of termination pursuant to this
          paragraph shall be canceled. Westinghouse will however accept orders
          from Distributor on C.O.D. terms for additional Products which
          Distributor is contractually obligated to furnish to its customers and
          does not have in its inventory, if Distributor notifies Westinghouse
          of any and all such obligations in writing within five (5) days of
          receipt of the termination notice. All such orders shall be priced in
          accordance with the pricing in effect at the time such orders are
          received by Westinghouse;

     (b)  WESTINGHOUSE SHALL NOT BE LIABLE IN ANY MANNER WHATSOEVER BECAUSE OF
          SUCH TERMINATION OR EXPIRATION, EVEN THOUGH THEREAFTER WESTINGHOUSE
          OR ANOTHER DISTRIBUTOR MAY COMPLETE ANY TRANSACTION INITIATED BY
          DISTRIBUTOR;

     (c)  NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR DAMAGES IN ANY FORM,
          BY REASON OF A TERMINATION PURSUANT TO THIS PARAGRAPH OF THIS
          AGREEMENT;

     (d)  Distributor shall discontinue immediately all advertising of or
          reference to Products upon termination or expiration of this Agreement
          and, at the request of Westinghouse, shall deliver to Westinghouse
          (F.O.B. point of destination, freight prepaid) all promotional,
          training or other product documentation or material in the
          Distributor's possession at the time of such termination;

     (e)  within fifteen (15) days of termination of this Agreement, the
          Distributor shall promptly remit to Westinghouse any and all moneys
          then due Westinghouse hereunder and shall promptly remit any further
          moneys which may become due Westinghouse after the date of such
          termination.

6.   Termination for Default. This Agreement may be terminated for default by -
     ------------------------

     (a)  Westinghouse if Distributor fails to make any payment when due in 
          accordance with the terms of this Agreement;

                                       4
<PAGE>
 
     (b)  either party in the event of a material breach of this Agreement by
          the other party if such breach is not cured within ten (10) days after
          written notice; or

     (c)  Westinghouse, in the case Distributor shall become insolvent, or file
          a voluntary petition in bankruptcy, or shall enter upon voluntary
          liquidation, or a petition in bankruptcy shall be filed against the
          Distributor or in the event of the appointment of a receiver for the
          business of Distributor, or an assignment by Distributor for the
          benefit of creditors.

     In the event Westinghouse terminates this Agreement for default,
     Distributor shall immediately discharge the accounting payment and other
     obligations set forth in Paragraph 5(e) above, cease using the Westinghouse
     name, remove all signage and return it as well as all promotional and
     training information to Westinghouse (F.O.B. point of destination, freight
     prepaid).

7.   Limitation of Liability.  The remedies of Distributor set forth in this
     -----------------------
     Agreement are exclusive and not withstanding any other provision in this
     Agreement or any statutory provisions, the liability of Westinghouse with
     respect to any claims of Distributor arising from the Products sold under
     this Agreement or anything done in connection herewith such as the
     performance thereof, or from the manufacture, sale, delivery, or resale or
     use of any Product covered by or furnished under this Agreement, whether in
     contract, in tort (including Westinghouse's negligence or strict liability)
     or otherwise, shall not exceed the actual amount paid by Distributor to
     Westinghouse for such Product. Westinghouse, its contractors and suppliers
     of any tier, shall not be liable beyond such amount in contract, in tort
     (including Westinghouse's negligence or strict liability) or otherwise for
     special or consequential damages, including, but not limited to, damage or
     loss of other property, loss of profits or revenue, loss of use of
     equipment, cost of capital, cost of purchased or temporary equipment
     (including additional expenses incurred in using existing facilities),
     claims of customers of Distributor or for any special, indirect, third
     party, incidental or consequential damages whatsoever.

8.   Force Majeure.  Westinghouse shall not be liable for failure to perform or
     -------------
     for delay in performance due to fire, flood, strike or other labor
     difficulty, act of God, act of any governmental authority or of the
     Distributor, riot, embargo, fuel or energy shortage, car shortage, faulty
     castings or forgings, wrecks or delay in transportation, inability to
     obtain necessary labor, materials or manufacturing facilities from usual
     sources or due to any other cause beyond its reasonable control. In the
     event of delay in performance due to any such cause, the date of delivery
     or time for completion will be extended by a period of time reasonably
     necessary to overcome the effect of such delay.

9.   Trademarks and Tradenames.
     -------------------------

     (a)  Distributor may not use the name "Westinghouse", or any name of the
          equipment identified in Exhibit A or any abbreviation or modification
          thereof except for the limited purpose of identifying itself as an
          authorized distributor of the Equipment. Distributor shall not grant
          this privilege to any third parties or affiliated companies.
          Distributor may not use the name "Westinghouse" or any other trademark
          or tradename of Westinghouse in any promotional, advertising and other
          materials or as a part of its firm or corporate title in signs or
          letterheads, without prior written approval of Westinghouse.

     (b)  Effective upon the date of termination of this Agreement, Distributor
          shall immediately discontinue the use of said trademarks and
          tradenames in any manner except for use in catalogs or other printed
          material which reference the names and/or trademarks of more than one
          company. Such material may be used until the next reissue of such
          catalogs or printed material but in no event after six (6) months
          following termination. During such period, Distributor shall inform
          its customers that it no longer handles the Products.

                                       5

10.  Distributor's Financial Condition.  Distributor shall maintain and employ,
     ---------------------------------
     in connection with its business under this Agreement, such working capital
     and net worth as may be required by Westinghouse's reasonable opinion to
     enable Distributor to carry out and perform all of Distributor's
     obligations under this Agreement. Distributor shall make available to
     Westinghouse such financial reports and data as Westinghouse may from time
     to time request to determine Distributor's financial condition.
     Westinghouse reserves the right at all time, either generally or with
     respect to any specific purchase order, to change or limit the amount or
     duration of credit allowed to Distributor. Westinghouse may, at its option,
     require that all shipments to Distributor be made of a C.O.D. basis or
     other arrangement protecting Westinghouse's interest. Distributor shall
     execute and deliver such security agreements, financing statements and
     other agreements, instruments, UCC forms and other documents as
     Westinghouse shall request to protect Westinghouse's interest in the
     Products and all proceeds thereof.

11.  Indemnity and Insurance.
     -----------------------

     (a)  Distributor shall indemnify and hold harmless Westinghouse from all
          liabilities, losses, costs, damages, judgment and expenses including
          attorney's fees and costs, arising out of or related to any breach of
          this Agreement by Distributor or other activities of Distributor,
          including its officers, employees and agents.

     (b)  During the term of this Agreement, Distributor shall maintain in full
          force and effect fire and extended coverage insurance covering all its
          inventory of Products and parts and accessories therefor in an amount
          not less than the purchase price thereof. Such policy shall name
          Westinghouse as an additional insured and shall provide that it will
          not be cancelled or modified without at least thirty (30) days prior
          written notice to Westinghouse. Upon execution of this Agreement,
          Distributor shall furnish Westinghouse with certificates of insurance
          evidencing the existence of such coverage.

12.  Confidentiality.  Distributor shall not use or disclose to others any
     ---------------
     confidential or proprietary information of Westinghouse acquired in
     connection with this Agreement unless authorized in writing by
     Westinghouse.

13.  Intellectual Property Rights.  Westinghouse shall (a) at its own expense,
     ----------------------------
     defend or at its option settle, any claim, suit or proceeding brought
     against Distributor for infringement of any United States patent or
     copyright in connection with any Products supplied by Westinghouse to
     Distributor under this Agreement; and (b) pay any final judgment entered
     against Distributor on such issue in any such claim, suit or proceeding
     defended by Westinghouse; subject to the conditions that Distributor should
     provide Westinghouse notice of any such claim, suit or proceeding promptly
     after Distributor shall receive notice or obtain knowledge thereof, and, at
     Distributor's expense, provide full information and assistance as requested
     by Westinghouse in such defense. Westinghouse may, in the event of any such
     claim, suit or proceeding, modify or replace the affected Products to
     eliminate the alleged infringement or give Distributor a refund of the
     price of the affected Products in lieu of any other obligations or
     responsibilities hereunder. Notwithstanding the foregoing, Westinghouse
     shall have no liability for any costs or expenses incurred without
     Westinghouse's prior written authorization, and in no event shall
     Westinghouse's total liability to Distributor under this provision exceed
     the aggregate sum paid by Distributor to Westinghouse for the affected
     Products. The foregoing states the entire responsibility of Westinghouse
     with respect to any alleged intellectual property right infringement or
     violation in connection with the Products, and Westinghouse shall in no
     event be liable for loss of use or for incidental, indirect or
     consequential damages, whether in contract or in tort, by virtue of any
     such infringement or violation. No sale under this Agreement shall convey
     any license by implication, estoppel or otherwise under any proprietary or
     patent rights of Westinghouse except for the right to resell Products in
     accordance with this Agreement.

14.  Training.  An operator's manual shall be included with each purchase of a
     --------
     complete Westinghouse Mobile Satellite Telephone System. Distributor hereby
     agrees that it shall provide the necessary training to its customers. On a
     quarterly basis, as deemed necessary, Westinghouse will provide training in
     a centralized area of the territory listed in Exhibit B. In addition,
     Westinghouse shall provide limited training in support of the operator's
     manual as specified in Exhibit C.

15.  General.
     --------

     (a)  This Agreement shall inure to the benefit of and be binding upon
          Distributor and its successors and assigns, but shall not be
          assignable by Distributor without the prior written consent of
          Westinghouse. Any purported assignment or delegation of performance
          without the prior written consent of Westinghouse shall be null, void
          and of no effect.

     (b)  Distributor shall give Westinghouse notice of any proposed transaction
          affecting the ownership of ten percent (10%) or more of Distributor's
          capital stock, if Distributor shall be a corporation, the interest or
          any portion thereof of any partner, if Distributor shall be a
          partnership, or the ownership of all or any part of the business, if
          Distributor shall be an individual proprietorship.

     (c)  Except as hereinafter provided, all questions or controversies arising
          out of or in any manner relating to this Agreement shall be submitted
          to arbitration in Baltimore, Maryland according to the rules of the
          American Arbitration Association, and the award or decision made by
          the arbitrator or arbitrators therein shall be binding upon the
          parties. A judgment consistent therewith may be entered in any court
          of competent jurisdiction. Nothing herein contained shall be construed
          as in any way affecting Westinghouse's right to institute and 
          prosecute a lawsuit in any court of competent jurisdiction to effect
          the collection of any monies due to Westinghouse from Distributor or
          to protect trademark rights or copyrights. The arbitrability of any
          issue shall be determined in accordance with the Federal Arbitration
          Act.

     (d)  If applicable, any exporting of Products from the United States or re-
          exporting of Products from Canada is by Distributor and not
          Westinghouse. Distributor shall be responsible, at its own risk and
          expense, for any export license or permit and any other approval or
          documentation which may be required for or in connection with the
          export and/or re-export of any Products.

     (e)  This Agreement supersedes any and all prior agreements between the
          parties and constitutes the complete, final and exclusive
          understanding of the parties with respect to the subject matter. All
          prior negotiations, representations or promises, whether oral or
          written, of either party shall be deemed to have been merged herein.

     (f)  No amendment, change or attempted waiver of this Agreement shall be of
          any effect unless set forth in writing and duly signed on behalf of
          the party against whom it is thought to be enforced. Failure of
          Westinghouse to enforce at any time any of the provisions of this
          Agreement or any right it may have with respect thereto or to exercise
          any option herein provided shall in no way be considered to be a
          waiver of such provisions or rights or in any way affect the validity
          of this Agreement. The exercise by Westinghouse of any of its rights
          hereunder or any of its options hereunder under the terms or covenants
          herein shall not preclude or prejudice Westinghouse from thereafter
          exercising the same or any other right it may have under this
          Agreement irrespective of any previous action or proceeding taken by
          Westinghouse hereunder.

     (g)  If any part of this Agreement shall be invalidated for any reason,
          such part shall be deleted and the remainder shall be unaffected and
          shall continue in full force and effect.

     (h)  Any failure on the part of either party to enforce at any time for any
          period of time any provision of this Agreement shall not be deemed or
          construed to be a waiver of such provision or of the right of that
          party thereafter to enforce any provision or any other provision of
          this Agreement.

IV.  Terms of Sale to Skysite

4.1  Skysite shall purchase Products solely upon the terms and conditions 
contained in this Agreement. Any different terms and conditions in Skysite's 
purchase order forms or other writings shall not be binding upon the parties.

4.2  Payment for Products purchased by Skysite shall be in accordance with the 
invoices therefor, without deduction of any kind that has not been authorized in
advance by credit memorandum from MELA. All prices are F.O.B. MELA's Rancho 
Dominguez, California shipping point and are subject to change by MELA at any 
time upon thirty (30) days notice to Skysite. Price quotations based on 
estimated quantities are subject to increase in the event actual quantities 
purchased are less than the estimated or projected quantities.

4.3  MELA shall notify Skysite in the event of an announced reduction in the
price of Products and the effective date of such reduction. In the event that a
decrease in price for the Products becomes effective after MELA accepts an order
from Skysite for the Products but priot to shipment of the Products which are
the subject of such order, the price of the Products ordered shall be the price
in effect at the time of shipment. Within ten (10) days of Skysite's receipt of
MELA's notice of a price reduction, Skysite shall provide MELA with a list of
Products in its inventory purchased from MELA within thirty (30) days prior to
the date of such reduction. Subject to MELA's verification of the listed
Products, MELA shall issue to Skysite a credit memorandum covering the
difference in price of such Products.

4.4  Title and risk of loss or damage to all Products sold by MELA to Skysite
shall pass to Skysite upon delivery of Products by MELA to the carrier. MELA
shall, if not otherwise directed by Skysite, without incurring any liability,
exercise its own discretion in selecting the method of shipment and the carrier.
Skysite shall have the responsibility to file any claims with the carrier.

4.5  Prices do not include any taxes, levies, duties and fees of any kind, 
nature or description whatsoever applicable to the sale of any Products by MELA 
to Skysite, and Skysite shall forthwith pay to MELA all such sums upon demand, 
except for any such taxes as to which Skysite shall provide MELA, at the time of
the submission of its purchase order, documentation acceptable to MELA and the 
appropriate taxing authority establishing exemption therefrom. The parties 
acknowledge that no such taxes, levies, duties and fees are currently due or 
pending.

4.6  Delivery dates as set forth in any purchase order or confirmation thereof 
are only estimates. MELA shall not be liable to Skysite, and Skysite shall not 
be relieved of its obligation to accept such shipment, by virtue of any delay in
or failure of delivery.

4.7  MELA may allocate available inventory of Products among its customers, but 
in such a manner as MELA, may, in its sole discretion, deem appropriate.

                                       3
<PAGE>
 
4.8   All purchase orders for Products are subject to acceptance by MELA, and
MELA shall have the right at any time, in its sole discretion, to reject or to
decline to fill any purchase order, either in whole or in part.

4.9   MELA shall have the right, at any time, to effect changes in, or
discontinue the sale or availability of, any or all of the Products, as well as
any parts or components thereof without notice or liability to Skysite upon
thirty (30) days notice to Skysite.

4.10  MELA provides end users a written limited warranty specifically applicable
to each model of Products. A copy of MELA's current limited warranty is attached
hereto as Exhibit B and made a part hereof. MELA may, at its sole option, change
the duration and terms of such warranties at any time upon written notice to
Skysite. Such warranties shall establish exclusively the extent of MELA's
responsibilities for any failure of or defect in Products.

4.11  MELA shall make the final determination, in its sole discretion, whether
any Product is covered by the End User Limited Warranty. Without limiting MELA's
discretion to make such final determination, MELA may determine that a Product
is ineligible for service under such warranty if: (a) the Product has been
altered or repaired other than with authorization from MELA and in accordance to
its approved procedures; (b) the Product has been subjected to misuse, abuse,
accident, improper maintenance or negligence; or (c) the Product has had a
serial number or any part thereof altered, defaced or removed. If MELA
determines that a warranty claim was improperly made, MELA shall so advise
Skysite, and, in such event, Skysite shall pay to MELA upon invoicing by MELA
(x) for service performed, at MELA's then-current rates, (y) for replacement
parts, if any, at MELA's then-current prices and (z) for freight and handling
for returning the Product to Skysite.

4.12  MELA MAKES NO WARRANTIES WITH RESPECT TO THE PRODUCTS OF ANY KIND
WHATSOEVER, EXPRESS OR IMPLIED, EXCEPT AS SPECIFICALLY PROVIDED IN MELA'S
WRITTEN LIMITED WARRANTIES AS IN EFFECT FROM TIME TO TIME. THE IMPLIED
WARRANTIES OF MECHANTABILITY AND FITNESS FOR ANY PARTICULAR PURPOSE ARE HEREBY
DISCLAIMED AND EXCLUDED. MELA SHALL NOT BE LIABLE TO SKYSITE OR ANY THIRD
PARTIES FOR ANY INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES.

V.    Minimum Volume Commitment, Prices and Marketing Funds

5.1   During the initial term of this Agreement, Skysite shall purchase and take
delivery of the OmniQuest phones in the quantities, at the prices and pursuant
to the schedule set forth in Exhibit A to this Agreement (the "Minimum Volume
Commitment"). Upon execution of this Agreement, Skysite shall deliver to MELA
its purchase order for the Minimum Volume Commitment (MVC).

5.2   MELA shall provide Skysite with a number of OmniQuest units equal to 1% of
the Minimum Volume Commitment as "hot swap" consigned inventory to be used by
Skysite in its over the counter exchange program for claims covered under MELA's
limited warranty.

                                       4
<PAGE>
 
5.3    The initial prices for the Products shall be those specified in Exhibit A
to this Agreement. MELA reserves the right to increase or decrease any prices 
for the Products at any time, with notice to Skysite after the effective date of
such increase or decrease. Skysite acknowledges that the prices specified in 
Exhibit A are based on Skysite's commitment to comply with the MVC and that the 
prices shall be adjusted if Skysite does not meet this commitment. In the event 
that Skysite does not comply with the MVC, MELA shall have the right to 
determine price adjustments for all Products purchased thereafter pursuant to 
this Agreement during such term based upon the number of Products actually 
purchased by Purchaser, as provided in the manufacturer's price list. In the 
event MELA increases prices for the products for reasons other than 
non-compliance with MVC, then Skysite may within 30-days of such increase reduce
the MVC for all periods thereafter.

5.4    Skysite may reschedule the delivery of a shipment of OmniQuest phones 
under any purchase order with a minimum of ten days' notice to MELA prior to the
originally scheduled shipment date under such purchase order. A purchase order 
may only be rescheduled once, up to a maximum of 60 days after the originally 
scheduled shipment date. In addition, Skysite may, in a single instance with 
respect to each purchase order, request an increase in the quantity of Product 
to be delivered, on no less than ten days' prior notice to MELA and MELA shall 
use every reasonable effort to accommodate such change.

5.5    MELA shall provide Skysite with a marketing credit of $100 per OmniQuest 
unit purchased by and delivered to Skysite under this Agreement. Skysite shall 
use these marketing funds to support the OmniQuest phone and to assist Skysite 
in selling the phones to dealers and resellers. In addition, Skysite shall 
receive a 10% rebate on all OmniQuest phones in excess of the Minimum Volume 
Commitment purchased by and delivered to Skysite before October 31, 1998. MELA 
shall specify these monies as credits on its invoices to Skysite.

5.6    In the event Skysite fails to purchase the Minimum Volume Commitment, 
Skysite shall pay to MELA as liquidated damages, and not as a penalty, an amount
equal to $200.00 times the number of units which Skysite fails to purchase. The 
Minimum Volume Commitment shall be reduced by the number of units ordered by 
Skysite which MELA fails to deliver for reasons not attributable to Skysite or 
force majeure.

VI.    Training

6.1    MELA shall include an operator's manual with each unit mobile satellite 
phone and push-to-talk microphone purchased by Skysite under this Agreement. In 
addition, MELA shall, at no additional charge to Skysite, provide such training 
as MELA determines to be reasonably necessary to support Skysite's level of 
purchases of Products and to train Skysite's personnel in the operation, use and
maintenance of the Products. All costs associated with attending training 
classes, such as transportation, lodging, and meals, shall be at Skysite's sole 
cost. The number, location, size and scheduling of classes shall be in MELA's 
sole discretion.

                                       5
<PAGE>
 
VII.  Export Control

7.1  MELA is selling the Products to Skysite for resale and use within the 
United States. If Skysite chooses to export any Product (or any technology 
related thereto), Skysite shall be responsible for complying with the United 
States Export Administration Act as amended from time to time, with the Export 
Administration Regulations promulgated from time to time thereunder and with all
other export laws and regulations of the United States and all amendments, 
modifications or additions thereto, including all laws and regulations relating 
to re-export. Skysite shall indemnify and hold MELA harmless from any liability,
damages, costs and expenses arising from or connected with a breach of Skysite's
obligations under this Article.

7.2  Skysite shall execute any documents reasonably requested by MELA (including
written assurances of non-reexportation) including but not limited to Exhibit D 
attached, for the purpose of complying with the United States laws and 
regulations referred to in Section 7.1.

VIII.  Skysite's Financial Condition

8.1  Skysite shall make available to MELA such publicly available financial 
reports and data as MELA may from time to time reasonably request to determine 
Skysite's financial condition. MELA shall provide Skysite with a 30 day, 
non-interest bearing line of $200,000 line of credit to be used solely for the 
purchase of Products under this Agreement; provided, however, MELA reserves the 
right at all times, either generally or with respect to any specific purchase 
order, to change or limit the amount or duration of credit allowed to Skysite. 
MELA may, at its option, require that all shipments to Skysite be made on a 
C.O.D. basis or other arrangement protecting MELA's interest. Skysite shall 
execute and deliver such security agreements, financing statements and other 
agreements, instruments, UCC forms and other documents as MELA shall request to 
protect MELA's interest in the Products and all proceeds thereof.

IX.  Indemnity and Insurance

9.1  Skysite shall indemnify and hold harmless MELA from all liabilities, 
losses, costs, damages, judgments and expenses, including attorney's fees and 
costs, arising out of or related to any breach of this Agreement by Skysite or 
other activities of Skysite, including its officers, employees and agents under 
this Agreement.

9.2  During the term of this Agreement, Skysite shall maintain in full force and
effect fire and extended coverage insurance covering all its inventory of
Products and parts and components therefor in an amount not less than the
purchase price thereof. Such policy shall name MELA as an additional insured and
shall provide that it will not be canceled or modified without at least 30 days
prior written notice to MELA. Upon execution of this Agreement, Skysite shall
furnish MELA with certificates of insurance evidencing the existence of such
coverage.

                                       6

X.  Trademarks

10.1  Skysite acknowledges that Skysite has no rights or interests in any trade 
name or trademark used on or affixed to any Products or owned, used or claimed 
by MELA. Skysite shall not use any trademark or trade name as part of its 
corporate or business name. Skysite shall have the right to use such trademarks 
and trade names as appear on the Products and on MELA's promotional materials 
therefor in any manner approved by MELA. Skysite shall not remove, alter or 
obliterate any trademarks or country of origin markings which appear on 
Products.

XI.  Confidentiality

11.1  The terms of the Confidentiality Agreement, dated November 7/th/, 1997, 
between Skysite and MELA shall apply to this Agreement as though fully 
incorporated herein. A copy of the Confidentiality Agreement is attached as 
Exhibit C to this Agreement.

XII.  Term and Termination

12.1  Unless sooner terminated in accordance with this Article 12, this 
Agreement shall have an initial term of one (1) year from the date first above 
written. Thereafter, this Agreement shall be renewed automatically for 
successive for one-year terms.

12.2  Either party may terminate this Agreement at any time during the initial 
or any renewal term with cause or without cause by giving the other party notice
of termination (a) immediately if with cause and (b) not less than 30 days prior
to the effective date of termination if without cause.

12.3  This Agreement shall terminate automatically without any notice if either 
party: (a) ceases to function as a going concern; (b) is adjudged insolvent or 
bankrupt; (c) institutes or has instituted against it any proceeding seeking 
relief, reorganization or arrangement under any laws relating to bankruptcy; (d)
makes an assignment for the benefit of creditors; (e) has appointed a receiver,

dissolves or winds up its business.

12.4  Immediately upon termination of this Agreement: (a) except for the sale in
the ordinary course of business of inventory not repurchased by MELA, Skysite 
shall cease to represent itself as an authorized Distributor for the Products 
and shall discontinue all conduct or representations which might lead Skysite's 
customers or the public to believe that Skysite is authorized by MELA to sell 
Products; and (b) all amounts payable by Skysite to MELA shall become 
immediately due and payable.

12.5  In the event MELA terminates this Agreement without cause, MELA shall, at 
Skysite's request, repurchase from Skysite all or any part of Skysite's 
inventory of Products, at the lower of the then prevailing price to Distributors
for such Products or the net price paid by Skysite for the Products, upon 
condition that Skysite pay all transportation and other costs connected with 
shipping

                                       7




<PAGE>
 
such Products to MELA. Within five (5) days following receipt of notice of 
termination, Skysite shall furnish MELA a schedule of such Products which are 
new, undamaged and in their original packaging. MELA shall have the right for 
thirty (30) days following receipt of Skysite's inventory schedule to inspect 
Skysite's inventory. MELA shall give notice of its election to repurchase all or
part of such scheduled inventory after completion of MELA's inspection of such 
inventory or after expiration of the inspection period if no inspection is 
conducted.

12.6  Termination of this Agreement shall not release Skysite from the 
obligation to apply all sums which may be owing to MELA, whether then or 
thereafter due, or operate to discharge any liability that has been incurred by 
Skysite prior to any such termination. Neither party shall be liable to the 
other for damages of any nature, whether direct, indirect, incidental,
consequential or otherwise, as a result of the termination of this Agreement, 
including but not limited to any claims for lost profits, loss of goodwill or 
expenditures made or omitted in reliance on the continuation of this 
Agreement.

XIII.  No Agency

13.1  The relationship between MELA and Skysite is that of vendor and purchaser.
This Agreement does not establish a franchise, joint venture, agency or 
partnership between the parties, nor does it create an employer-employee 
relationship. Skysite is an independent contractor and shall not have authority 
or power to bind MELA, to create any liability binding upon MELA, to incur any 
obligation on behalf of MELA nor to represent that MELA is in any way 
responsible for Skysite's acts or omissions. Skysite shall be solely responsible
for all investments made and expenses incurred in connection with the 
establishment and operation of its business, and MELA shall have no obligation 
to Skysite in connection with any such investment or expenses.

XIV.  Intellectual Property Rights

14.1  Subject to the conditions set forth in this article, MELA shall, at its 
own expense indemnify and defend or at its option settle any claim, suit or 
proceeding brought against Skysite for infringement of any United States patent 
or copyright in connection with any Products supplied by MELA to Skysite under 
this Agreement. Subject to the limitations set forth in this section, MELA shall
pay any final judgment entered against Skysite on such issue in any such claim, 
suit or proceeding defended by MELA. MELA's obligation under this section shall 
be subject to the conditions that Skysite provide MELA notice of any such claim,
suit or proceeding promptly after Skysite shall receive notice or obtained 
knowledge thereof, and, at Skysite's expense, provide full information and 
assistance as reasonably requested by MELA in such defense. MELA reserves the 
right in the event of any such claim, suit or proceeding to modify or replace 
the affected Products to eliminate the alleged infringement or to give Skysite 
a refund of the price of the affected Products, in which event, MELA shall have 
no further liability to Skysite except for its obligation to indemnify and 
defend Skysite against third party claims as set forth in this Section 14.1

                                       8
<PAGE>
 
14.2   Notwithstanding the foregoing, MELA shall have no liability for or any 
responsibility with respect to any infringement arising out of: (a) the 
combination of any Products with any other product whether or not furnished to 
Skysite by MELA; or (b) modification of any Products unless such modification 
was made by MELA. MELA shall not be liable for any costs or expenses incurred 
without MELA's prior written authorization, and in no event shall MELA's total 
liability to Skysite under, or as a result of compliance with, this section 
exceed the aggregate sum paid to MELA by Skysite for the affected Products. The 
foregoing states the entire responsibility of MELA and the exclusive remedy of 
Skysite with respect to any alleged intellectual property right infringement or 
violation in connection with Products, and MELA shall in no event be liable for 
loss of use or for incidental, indirect or consequential damages, whether in 
contract or in tort, by virtue of any such infringement or violation. No sale 
under this Agreement shall convey any license by implication, estoppel or 
otherwise under any proprietary or patent rights of MELA except for the right to
resell Products in accordance with this Agreement.

XV.    Arbitration

15.1   Except as hereinafter provided, all disputes arising out of or in any 
manner relating to this Agreement which the parties do not resolve in good faith
within ten days after either party notifies the other of its desire to arbitrate
such dispute or controversy shall be settled by arbitration by a single 
arbitrator in accordance with the then standard prevailing commercial rules, as 
modified or supplemented by this article, of the American Arbitration 
Association ("AAA"). The arbitration shall be held in Washington, D.C. The
arbitration award shall be in writing and shall specify the factual and legal
bases of such award. The arbitration award shall be final and binding, and a
judgment consistent therewith may be entered by any court of competent
jurisdiction. The parties agree that the arbitration award shall be treated
confidentially, and the parties shall not, except as otherwise required by law
or court order, disclose the arbitration award to any third party, excluding
personnel in their affiliated companies and their attorneys and accountants with
a need to know, provided that such recipients agree to be bound by the same
restrictions as are contained in this Agreement. The arbitrator shall not have
the power to render an award of punitive damages. To the extent of any conflict,
this article shall supersede and control AAA rules.

15.2   Nothing in this article shall be construed to preclude or in any way 
prohibit MELA from (1) seeking any provisional remedy, such as injunction or a 
temporary restraining order, to enforce Articles X and XI of this Agreement or 
(2) instituting or prosecuting to judgment any lawsuit in any court of 
competent jurisdiction to collect any moneys due from Skysite.

15.3   Except as provided in this section, neither MELA nor Skysite shall have 
the right to take depositions or obtain discovery of documents or other 
information which is relevant to the subject matter of any arbitration which is 
required under Section 15.1 of this Agreement. After the appointment of the 
arbitrator, MELA and Skysite shall agree on (1) a reasonable number of and 
schedule for depositions which the parties may take and (2) a reasonable scope 
and schedule for the production of documents or other information which is 
relevant to the subject matter of the arbitration. If MELA and Skysite cannot 
reach agreement on the number of depositions, the scope of

                                       9
<PAGE>
 
production of documents or other information and the schedule therefor, the 
arbitrator shall make such determination(s). All discovery shall be completed no
later than 30 days prior to the arbitration hearing. The arbitrator shall have 
the power to enforce any discovery agreed upon by the parties or otherwise 
required to be taken pursuant to this section by imposing the same terms, 
conditions, sanctions and penalties as can be or may be imposed in like 
circumstances in a civil action by the Washington, D.C. Court, except the power 
to order the arrest or imprisonment of a person.

15.4  No later than 30 days prior to the arbitration hearing, each party shall 
produce to the other party and the arbitrator lists of the witnesses, documents 
and other information which such party intends to use at the arbitration 
hearing.

XVI.  General Provisions

difficulty; (b) war, insurrection, rebellion or civil disturbance; (c) 
governmental action, inaction or authority; (d) fire, flood, freezing, storm or

null, void and of no effect.

16.3  No waiver of, or the failure of either party to require strict compliance 
with, any provision of this Agreement in any respect shall be deemed to be a 
waiver of such party's right to insist upon strict compliance with such
provision or with all other provisions of this Agreement. No waiver by either
party of any breach of or default under this Agreement shall constitute a waiver
of any other or subsequent breach or default. No waiver shall be binding unless
duly executed in writing by the party against whom the waiver is sought to be
enforced.

16.4  This Agreement supersedes any and all prior understandings and agreements,
whether oral or written, entered into between Skysite and MELA with respect to 
the subject matter of this Agreement and each party acknowledges that there are 
no warranties, representations, covenants or understandings of any kind, nature 
or description whatsoever made by either party to the other, except as are 
expressly set forth in the Agreement.

16.5  This Agreement shall not be subject to change or modification, except by 
Agreement in writing duly executed by the parties.

16.6  If and to the extent that any provision of this Agreement shall be

or in part invalid or unenforceable, such provision or

                                      10

part shall be deemed to be surplusage and to the extent not so determined to be 
invalid or unenforceable, each remaining provision of this Agreement shall 
remain in full force and effect.

         to enforce any arbitration award and any other legal action between the
         parties pursuant to or relating to this Agreement or the transactions

         allegation that it is an agency or instrumentality of a sovereign
         state. Any award of the arbitrators shall be enforceable by any court
         having jurisdiction over the party against whom the award has been

     This Satellite Minutes Commitment Plan (the "Plan") is dated as of 10 
                                                                        --
August, 1998 and is by and between Iridium U.S., L.P., d/b/a Iridium North 
- ------
America ("INA") and Project 77, Inc. ("Service Provider").
                    ----------------

                                   RECITALS

     Whereas, INA and Service Provider have entered into a service provider 
agreement, dated November, 1997 (the "Service Provider Agreement") to provide 
                 --------  ----
Iridium satellite services and the parties now desire to modify the pricing 
structure set forth therein;

     Whereas, Service Provider desires to obtain favorable pricing rates based 
upon outbound minutes of domestic and international Iridium homed satellite use 
purchased and paid for by Service Provider ("Satellite Minutes") specifically 
excluding any promotional or other free minutes of use and INA desires to obtain
a firm commitment from Service Provider for its Satellite Outbound Minutes over 
a fifteenth month period; and

     Whereas, INA and Service Provider desire to enter into this Plan upon the 
terms and conditions set forth herein.

                                   AGREEMENT

     Now, therefore, in consideration of the mutual agreements and 
understandings herein contained, the parties hereto agree as follows:

1.   Commitment Plan.  INA is offering a volume pricing plan based upon Service 
     ---------------
     Provider's level of commitment. The purpose of this Plan is to grant
     favorable pricing to Service Provider for cultivating additional Satellite
     Minutes through increased sales and Iridium subscribers. In addition, this
     Plan is designed to hold Service Provider accountable to its commitment and
     discouraging Service Provider from making unrealistic or impractical
     commitments, thereby gaining a market pricing advantage relative to other
     service providers.

2.   Commitment.  During the term of this Plan, Service Provider hereby agrees 
     ----------
     to commit to the (Initial One of the following):

           Entry Level Program and a minimum gross revenue of $500,000.00.
     -----

           Second Level Program and a minimum of 1,000,000 Satellite Minutes.
     -----

     /s/PM Third Level Program and a minimum of 3,000,000 Satellite Minutes.
     -----

Service Provider shall be entitled to the pricing and rebate structure and 
obligated to the assessment set forth below associated with the program selected
above.

<PAGE>
 
Entry Level Program.
- -------------------

     Pricing. Service Provider shall be charged the standard rates for 
Satellite Minutes (the "Standard Rate") which are contained in Exhibit B to the 
                                                               ---------
Service Provider Agreement.

     Commitment. Service Provider shall guaranty INA minimum gross revenue from 
Satellite Minutes equal to $500,000.00 during the term of this Plan.

     Assessment. If Service Provider fails to purchase at least $500,000.00 of 
Satellite Minutes, Service Provider shall pay to INA the difference between the 
gross revenue received from Service Provider for Satellite Minutes and 
$500,000.00 thirty days after the end of the term of this Plan.

     Termination. If Service Provider fails to purchase at least $500,000.00 of 
Satellite Minutes, INA shall have the option of terminating the Service Provider
Agreement, in its sole and absolute discretion.

Second Level Program.
- --------------------

     Pricing. Service Provider shall be charged the Standard Rate of Satellite 
Minutes less a five percent (5%) discount. Once Service Provider reaches the 
first price breakpoint by purchasing 2,000,000 Satellite Minutes during the term
of this Plan, INA shall increase the applicable discount off of the Standard 
Rate to seven percent (7%) for Satellite Minutes purchased thereafter. Once 
Service Provider reaches the second price breakpoint by purchasing 3,000,000 
Satellite Minutes during the term of this Plan, INA shall increase the 
applicable discount off of the Standard Rate to ten percent (10%) for Satellite 
Minutes purchased thereafter.

     Commitment. Service Provider agrees to purchase a minimum of 1,000,000 
Satellite Minutes during the term of this Plan.

     Rebates. If Service Provider reaches the first price breakpoint by 
purchasing 2,000,000 Satellite Minutes during the term of this Plan, INA shall 
credit Service Provider with a rebate. The rebate shall be calculated by taking 
two percent (2%) of Service Provider's Blended Rate (defined below) and 
multiplying the product thereof by one million (1,000,000). If Service Provider 
purchases 3,000,000 Satellite Minutes during the term of this Plan, INA shall 
credit Service Provider with a second rebate. The second rebate shall be 
calculated by taking three percent (3%) of Service Provider's Blended Rate and 
multiplying the product thereof by one million (1,000,000).

     Assessment. If Service Provider's Satellite Minutes are less than 1,000,000
at the end of term of this Plan, Service Provider shall pay INA an assessment 
for each unused Satellite Minute within thirty days from the end of this Plan. 
The assessment shall be equal to the difference between 1,000,000 and Service 
Provider's Satellite Minutes multiplied by $1.00. For example, assume a Service 
Provider's Satellite Minutes are 800,000 at the end of this Plan. In this case 
the difference between the Service Provider's Satellite Minutes and its 
commitment is 200,000. Therefore, the Service Provider's assessment will be 
equal to $200,000.00 ([1,000,000 - 800,000] * $1.00).

Third Level Program.
- --------------------

     Pricing.  Service Provider shall be charged the Standard Rates for 
Satellite Minutes less a ten percent (10%) discount. Once Service Provider 
reaches the first price breakpoint by purchasing 4,000,000 Satellite Minutes 
during the term of this Plan, INA shall increase the applicable discount off of 
the Standard Rate to twelve percent (12%) for Satellite Minutes purchased 
thereafter. Once Service Provider reaches the second price breakpoint by 
purchasing 5,000,000 Satellite Minutes during the term of this Plan, INA shall 
increase the applicable discount off of the Standard Rate to fifteen percent
(15%) for Satellite Minutes purchased thereafter.

     Commitment.  Service Provider agrees to purchase a minimum of 3,000,000 
Satellite Minutes during the term of this Plan.

     Rebate.  If Service Provider reaches the first price breakpoint by 
purchasing 4,000,000 Satellite Minutes during the term of this Plan, INA shall 
credit to Service Provider a rebate. The rebate shall be calculated by taking 
two percent (2%) of Service Provider's Blended Rate (defined below) and 
multiplying the product thereof by one million (1,000,000). If Service Provider 
reaches the second price breakpoint by purchasing 5,000,000 Satellite Minutes 
during the term of this Plan, INA shall credit to Service Provider a second 
rebate. The second rebate shall be calculated by taking three percent (3%) of 
Service Provider's Blended Rate and multiplying the product thereof by one 
million (1,000,000).

     Assessment.  If Service Provider's Satellite Minutes are less than 
3,000,000 at the end of the term of this Plan, Service Provider shall pay INA an
assessment for each unused Satellite Minute thirty days from the end of this 
Plan. The assessment shall be equal to the difference between 3,000,000 and 
Service Provider's Satellite Minutes multiplied by $1.00.

3.   Evaluation.  INA shall evaluate Service Provider's performance six months
     ----------
     from the Commencement Date and thereafter on a quarterly basis. If, in
     INA's sole and absolute discretion, INA determines that Service Provider
     will not be able to meet its commitment obligations contained herein, INA
     reserves the right to reduce or eliminate the pricing discount granted to
     Service Provider to recover the assessment described above. INA's decision
     not to modify the discount applied shall not effect Service Provider's
     commitment or the assessment due for failure to meet its commitment.

4.   Rebate Calculation.  Service Provider's Blended Rate shall be equal to the
     ------------------
     weighted average of the Standard Rate for Satellite Minutes during the
     applicable period. The "applicable period" shall mean the period between
     the billing cycle immediately following Service Provider's Satellite
     Minutes exceeding the prior price breakpoint and the billing cycle
     immediately following Service Provider's Satellite Minutes exceeding the
     current price breakpoint. Service Provider shall, within thirty (30) days
     of a written request therefor, reimburse INA for the full amount of any
     rebate credited hereunder which should not have been credited to Service
     Provider as the result of any re-calculation, for any reason, of the total

                           AMENDMENT TO ADDENDUM TWO
                  SATELLITE MINUTES COMMITMENT PLAN ADDENDUM

     The following terms and conditions are made a part of Addendum Two to the 
Iridium Service Provider Agreement between INA and Service Provider, to which it
is appended. When this Amendment is signed by both parties, the terms hereof 
shall supersede and control over any provisions of Addendum Two that are 
inconsistent herewith.

A.  Section 3, Evaluation. Section 3 is deleted in its entirety and replaced 
               -----------
with the following:

"3. Evaluation.  INA shall evaluate Service Provider's performance six months 
 -------------
from the Commencement Date and thereafter on a quarterly basis. The initial six 
month's performance review will be undertaken for all service providers as a 
group, and if a substantial majority of service providers have been unable to 
meet their program commitment levels, INA, at its sole and absolute discretion, 
may make reasonable and non-discriminatory adjustments to the rates and 
commitment levels applicable to service providers, including Service Provider. A
decision by INA not to modify the Program Level applied shall leave in effect 
Service Provider's commitment and the assessment due for failure to meet its 
commitment.

If during the initial six month's performance review, in INA's sole and absolute
discretion, INA determines that a general adjustment of rates and commitment 
levels is unnecessary but that Service Provider has not reached 300,000 
Satellite Minutes, INA shall adjust Service Provider's commitment to a lower 
level Program hereunder. INA shall have sole and absolute discretion as to which
lower level Program hereunder Service Provider's commitment will be adjusted. In
the case of such Program adjustment, Service Provider shall reimburse, as set 
forth in  Section 4 below, INA five percent (5%) of all Service Provider's 
actual charges incurred under this Agreement as of the date of such Program 
adjustment ("Recapture of Discount")."

B.  Section 4. Rebate Calculation. Section 4 is amended to add the following:
               ------------------

"The process provided herein shall apply to Rental Service Provider's payment of
the Recapture of Discount calculated pursuant to Section 3."

       forfeits an immediately payable penalty, which penalty shall be
       calculated as follows. The penalty due is the total of all subscriptions
       registered in the name of the Service Provider multiplied by an amount of
       US Dollars 875.- per subscription, In the event that only part of the
       data file is provided, the full penalty, as described in this paragraph,
       shall be due to Station 12. For every week that the Service Provider
       fails to comply with this obligation, the Service Provider forfeits an

          Subscriptions to Station 12. If agreement is reached, transfer of all
          Altus Subscriptions to Station 12 has to be effected at least 1 (one)

          Service Provider shall not owe Station 12 the monthly subscription
          charges for the remaining contract periods of such transferred Altus
          Subscriptions;

       b. in the event that transfer does not take place in accordance with the
          agreed conditions or in the event that no agreement on the transfer or
          the conditions relating to it, is reached, the Service Provider shall
          owe Station 12 the monthly subscription charges for the remaining

7.  TERM / TERMINATION
    ------------------

    (a)  Except as otherwise provided herein, this Agreement shall be in effect
         for the Initial Term. This Agreement shall automatically continue after
         the Initial Term until terminated by either SKYSITE or ARDIS upon
         twelve (12) months' written notice.

    (b)  Either party may terminate this Agreement upon six (6) months' written
         notice for failure of the other party to meet the applicable
         performance levels set forth in Paragraph 3(b). Should this contract be
         terminated pursuant to this Paragraph, ARDIS shall continue to provide
         ARDIS communication services to SKYSITE's then current users of the
         Services, provided (i) such users sign the then current standard ARDIS
         Airtime User Agreement, or (ii) an appropriate new remarketing
         agreement is signed between ARDIS and SKYSITE within thirty (30) days.

    (c)  Notwithstanding anything to the contrary contained herein, either
         SKYSITE or ARDIS may terminate this Agreement (i) upon any material
         breach by the other of its obligations under this Agreement, or (ii) if
         the other shall dissolve or commit an act of bankruptcy or become
         insolvent, by sending such party written notice of termination which
         shall state the nature of the breach. Such notice shall be effective
         thirty (30) days following the date hereof, unless such breach shall
         have been remedied during such thirty (30) day period. Notwithstanding
         the foregoing, this Agreement shall terminate immediately if the
         authorization held by ARDIS is revoked by the FCC.

                                                                          Page 3

 8.  DEFAULT AND REMEDIES
     --------------------

     If SKYSITE fails to make any payment of any sum due after thirty (30) days,
     ARDIS may add a service charge at the maximum rate permitted by applicable
     law. Such additional charge shall be due and payable upon receipt of
     invoice.

     If SKYSITE fails to make any payment of any sum due or fails to perform as
     required by any other provision hereunder, and continues in such failure
     for fifteen (15) days' after written notice has been sent by ARDIS to
     SKYSITE, SKYSITE shall be deemed in default under this Agreement.

     In the event of default, ARDIS has the right to immediately terminate this
     Agreement, retain all payments made hereunder, and deny SKYSITE and its
     customers any service provided under this Agreement by or through the ARDIS
     Network or Systems. Each and all of the rights and remedies of ARDIS
     hereunder are cumulative to and not in lieu of each and every other such
     right and remedy.

     There will be a $50.00 reactivation fee for customers who wish to re-
     establish service once ARDIS has suspended or terminated service.

     Failure or delay on the part of ARDIS or SKYSITE to exercise any right,
     remedy, power or privilege hereunder shall not operate as a waiver thereof.
     A waiver, to be effective, must be in writing and signed by the party
     making the waiver. A written waiver of a default shall not operate as a
     waiver of any other default or of the same type default on a future
     occasion.

 9.  FORCE MAJEURE
     -------------

     ARDIS and its subcontractors do not assume and shall have no liability
     under this Agreement for failure to provide, or delay in providing services
     due directly or indirectly to causes beyond the control of ARDIS or its
     subcontractors including, but not restricted to, acts of God, or
     governmental entities, or of the public enemy, or of SKYSITE, strikes, or
     unusually severe weather conditions.

10.  TRAINING AND TECHNICAL SUPPORT
     ------------------------------

     (a) ARDIS shall make available to SKYSITE, at no charge, reasonable initial
         training on the use of ARDIS Services.

     (b) ARDIS shall continue to provide SKYSITE, at no charge, with technical
         assistance performed by competent ARDIS employees in connection with
         ongoing use of the Services by SKYSITE and its customers. Such
         assistance shall include, without limitation, telephone consultation,
         updates relating to changes and enhancements to the Services and
         diagnostic services.

11.  THIRD PARTY LIABILITY
     ---------------------

     SKYSITE agrees to inform its clients and others to whom it remarkets ARDIS'
     services, of the applicable terms and conditions of this Agreement, as
     expressed in Exhibit III hereof, and warrants that it will not remarket the
     Services to anyone without obtaining a signed Agreement which contains the
     essence of ARDIS' disclaimer of all third party liability.

12.  CONFIDENTIAL INFORMATION
     ------------------------

     (a) SKYSITE and ARDIS agree that they will not disclose each other's
         confidential information and trade secrets relative to data, software,
         documentation, client names and addresses, and all other proprietary
         information to persons other than employees of each other required to
         have such disclosure for the furtherance of the purposes of this
         Agreement. Both SKYSITE and ARDIS shall take all steps reasonably
         calculated to protect such information from unauthorized disclosure.
         This obligation shall survive the termination of this Agreement.
         
                                                                          Page 4

<PAGE>
 
     (b)  Nothing in this Agreement shall cause either party to have any rights
          or licenses in any inventions, patents, trade secrets, trademarks
          and/or copyrights of the other relating to the subject matter of this
          Agreement.

13.  INDEPENDENT RELATIONSHIP
     ------------------------

     SKYSITE and ARDIS specifically disclaim any partnership relationship, and
     this Agreement shall in no way be construed to make SKYSITE and ARDIS
     partners or joint venturers. For the purposes of this Agreement, SKYSITE
     and ARDIS shall be deemed to be independent contractors. Furthermore, in
     the event SKYSITE elects to sell ARDIS services to the U.S. Government,
     U.S. State or Local or any foreign Government, or to a prime contractor
     selling to a Government customer, SKYSITE does so at their own option and
     risk and agrees not to obligate ARDIS as a subcontractor or otherwise to
     such customers. SKYSITE remains solely and exclusively responsible for
     compliance with all statutes, regulations, and clauses governing sales to
     the U.S. Government, State or Local or any foreign Government, or to a
     prime contractor selling to a Government customer. ARDIS makes no
     representations, certifications, or warranties whatsoever with respect to
     the ability of its goods, or services, or prices to satisfy any such
     statutes, regulations, or clauses.

14.  EXCLUSIVE REMEDY
     ----------------

     In the event of any failure or delay attributable to the fault of ARDIS or
     its subcontractors, or for breach of the warranty, SKYSITE's sole remedy
     shall be limited to a refund of SKYSITE's charges for the affected services
     during the time of such failure or delay. SKYSITE agrees, however, that no
     refund shall be made for a single failure or delay which does not exceed
     one hundred dollars ($100.00).

15.  LIMITATION OF LIABILITY
     -----------------------

     (a)  Neither party shall be liable for special, incidental, indirect or
          consequential damages under this Agreement, even if such party has
          been advised of the possibility of such damages.

     (b)  Except for SKYSITE's obligation to pay amounts owing under this
          Agreement, SKYSITE's and ARDIS' total liability for any other claim
          arising out of or in any way connected with this Agreement and the
          sole remedy regardless of the form of action (whether in contract,
          tort or otherwise) shall be actual damages not to exceed $50,000.

16.  INTEGRATION
     -----------

     This Agreement is the entire agreement between the parties with respect to
     the subject matter hereof, and no alteration, modification or

     C.   The Object of the Scheme to Defraud.

saw fit, including for their own benefit.

     D.   The Manner and Means of the Conspiracy.
          --------------------------------------

          It was part of the conspiracy that:

          1.  Defendants BINGHAM, HUDNALL and WATKINS would and did promote an 
investment program supposedly operated by Elderway and Oldburn.

          2.  Defendants BINGHAM, HUDNALL and WATKINS would and did claim that 
the investment program generated large profits by using investors' money to 
trade financial instruments through Smith Barney.

          3.  Defendants BINGHAM, HUDNALL, ROBICHAUX and WATKINS would and did 
use portions of the investors' money to trade financial instruments, but ended 
up losing millions of dollars.

          4.  Defendants BINGHAM, FARRAR, HUDNALL, ROBICHAUX and WATKINS would 
and did cause written reports to be sent to Switzerland that falsely claimed the
trading had resulted in large profits.

          5.  Defendants BINGHAM, HUDNALL and ROBICHAUX would and did instruct 
Smith Barney and Compass Bank to wire transfer millions of dollars of 
investors's principal to banks in Liechtenstien for distribution to the 
investors, so the investors would think the program was profitable and would 
invest even more money.

          6.  Defendants BINGHAM, DEAVOURS, FARRAR, HUDNALL, 


                                       3
<PAGE>
 
ROBICHAUX and WATKINS would and did induce foreign investors to wire transfer 
millions of dollars to Compass Bank, allegedly for the benefit of Smith Barney, 
when BINGHAM, DEAVOURS, FARRAR, HUDNALL, ROBICHAUX and WATKINS knew that Smith 
Barney was not receiving the money.

          7.   Each time an investor wire transferred money for participation in
the Elderway/Oldburn Investment program, defendants BINGHAM or ROBICHAUX would
and did sign a letter addressed to defendant DEAVOURS at Smith Barney.

          8.   Defendants BINGHAM, FARRAR, HUDNALL, ROBICHAUX and WADKINS would
and did cause millions of dollars of additional losses by using the investors'
money to buy houses, to pay $1.5 million dollars to IBS, to invest in failed
business ventures and to pay defendant DEAVOURS a secret monthly salary of
$10,000.
