ITEM 1. BUSINESS

FORWARD LOOKING STATEMENTS

             Portions of this Form 10-K report contain "forward looking"
statements that involve risks and uncertainties. The Company's actual results
may differ significantly from the results discussed in the forward looking
statements. Although the Company believes that the assumptions underlying the
forward looking statements contained herein are reasonable, any of the
assumptions could prove inaccurate, and therefore, there can be no assurance
that the forward looking statements included herein will prove to be accurate.
Factors that might cause such a difference include, but are not limited to,
market acceptance of the Company's products and services and other factors
discussed in "Business Risks" below and in "Risk Factors" of the Company's
Proxy Statement and Prospectus (included in its registration Statement on Form
S-4, Registration No. 333-37993), as well as the Company's subsequent filings
and reports with the Securities and Exchange Commission.

MERGER

         On December 30, 1997, Hayes Corporation (the "Company" or "Hayes"),
formerly known as Access Beyond, Inc. ("Access Beyond"), completed a reverse
triangular merger (the "Merger") with Hayes Microcomputer Products, Inc.
("Hayes Microcomputer").  In the Merger, the Company issued 15,261,763 shares
of Common Stock and 405,977 shares of Series A Preferred Stock, after giving
effect to a one for three reverse stock split effected February 25, 1998 (the
"reverse stock split").  The stock issued in the transaction represented 79% of
the outstanding stock immediately after the Merger excluding the effect of
warrants, stock options, and the 6% Cumulative Convertible Preferred Stock.
Immediately following the Merger, the Company changed its name to Hayes
Corporation.  Since the Hayes Microcomputer shareholders received a substantial
majority of the shares of stock of the Company, the transaction is treated as a
reverse acquisition of the Company by Hayes Microcomputer for accounting
purposes.  As a result, the historical financial statements of the surviving
company for the periods prior to the Merger are those of Hayes Microcomputer
rather than those of Access Beyond.

GENERAL

         Hayes engages in the design, manufacturing, marketing and support of
computer communication products for business, government, small office,
professional and individual consumers worldwide through the sale of modem,
access systems and broadband products.

         While historically Hayes' business has focused on its core modem
business, Hayes has recently broadened its products to include integrated
network communication products (access systems).  In addition, Hayes has
pursued penetrating the broadband market by offering products for the
asymmetric digital subscriber line ("ADSL") and the cable markets.

         For nearly two decades, Hayes has been the leader in providing
value-based modems.  The Hayes standard AT command set has become the de facto
industry standard for personal computer modems and, along with the patented
escape sequence, created the market requirement for "Hayes compatibility."

         Hayes was founded by Dennis Hayes in 1977 to develop and market modems
designed for the microcomputer marketplace.  Hayes' first product was released
in April 1977 which was a modem for the early S-100 type computers.  Hayes
developed the Micromodem II for the Apple II before Apple had a disk drive.
Hayes introduced the Smartmodem in June 1981.  In August 1981, IBM introduced
the first IBM PC that legitimized the personal computer industry.  Personal
computer ("PC") sales began to skyrocket and Hayes was the leading manufacturer
of modems to serve this market.  Fueled by the growth in the PC market and the
introductions of 1200 and 2400 bits per second modems, Hayes' sales grew from
$4.8 million in 1981 to $120.1 million in 1985.  Hayes was included twice in
Inc. Magazine's list of Fastest Growing Privately Owned Companies.


                                                                          Page 1


                                                                                
<PAGE>   4

         In the 1987 to 1988 time frame, the "low price" modem competition
began to consolidate into recognizable brands from the multitude of market
players.  By 1989, Hayes realized the significance of the emergence of what was
internally referred to as clone modems (claiming Hayes compatibility) as had
been observed with clone PCs (IBM compatible) slightly earlier.  Practical
Peripherals, Inc. had established itself as a true brand in the clone modem
segment.  In August 1989, Hayes purchased Practical Peripherals, Inc. to
establish a presence in the clone modem segment.

         In the early 1990s, the consumer, small office/home office ("SOHO")
market segment experienced rapid expansion.  In response, Hayes introduced the
ACCURA product line in 1993.  This product line provided a different feature
set and a lower price point than Hayes Ultra and Optima product lines.
Competitors in this market segment pursued an extremely aggressive price
strategy to gain market share by initiating rapid price erosion for this
market.

         Due to market price pressures, Hayes reduced its ACCURA pricing in
March 1994 to competitive levels.  As a result, the ACCURA volumes increased
dramatically.  In responding to the ACCURA volume increase, Hayes experienced a
number of operational and manufacturing problems.  Due to excess inventory of
old designs, Hayes could not benefit from new lower cost product designs.
Additionally, there was an inadequate internal infrastructure and process in
place to support subcontractor start-up necessary to support increased demand
and significant air freight expense was required due to resultant delays in
subcontractor production.  Inventory increased and margin compression occurred.
The resulting strain on Hayes' cash position and operating losses combined with
insufficient capitalization precipitated Hayes' filing a petition for relief
under Chapter 11 of the U.S. Bankruptcy Code on November 15, 1994.

         On April 16, 1996, Hayes consummated a court approved Reorganization
Plan (the "Plan").  Under the terms of the Plan, all prepetition creditors were
paid in full plus interest, except where other agreements were made.  Funding
of the Plan was provided through three major sources.  First, pursuant to the
Agreement and Plan of Merger dated April 12, 1996 entered into by and between
Rinzai Limited ("Acma"), Kaifa Technology (H.K) Limited ("Kaifa"), Rolling
Profit Holdings, Ltd., Lao Hotel (H.K.), Limited, Saliendra Pte Ltd., and S.P.
Quek Investments Pte. Ltd. (collectively, the "Investors"), certain
subsidiaries were created by the Investors which collectively contributed $35.0
million to fund the Plan and were merged with Hayes.  The Investors received
preferred stock representing a 49% voting interest in Hayes.  Second, Hayes
entered into an agreement with The CIT Group/Credit Finance, Inc. to borrow up
to an aggregate of $64.5 million through three separate debt instruments
collateralized by Hayes' intellectual property, certain equipment, and accounts
receivable and inventory balances.  Third, pursuant to the Plan, Hayes sold
certain parcels of real property for $8.2 million.  On October 9, 1997, Hayes
received the final decree bringing its Chapter 11 case to a close.

         During 1996, Mr. Hayes assembled a new management team comprised of
individuals from the communications industry including a new chief financial
officer and vice presidents of sales, engineering and human resources.

         On April 24, 1997, Hayes acquired Cardinal Technologies, Inc.
("Cardinal") which Hayes management believed added a highly visible brand to
Hayes' brand portfolio and strengthened Hayes' position in the North American
retail market. In connection with the Cardinal acquisition in April 1997, Hayes
received a $5.5 million investment from Vulcan Ventures, Inc., one of the Paul
Allen Group of Companies.  The investment involved the issuance of 263,113
shares of Series B Preferred Stock of Hayes Microcomputer, which was converted
into 405,977 shares of Series A Preferred Stock of the Company, after giving
effect to the reverse stock split.

PRINCIPAL PRODUCTS

         Hayes has invested in technologies that expand its products to meet
changing market demands.  Hayes' business is structured around three core
product categories: modems, broadband products and access systems.


                                                                          Page 2


                                                                                
<PAGE>   5

MODEMS

         Analog and ISDN modems represent the core of Hayes' business, and
accounted for approximately 96% of all revenues of Hayes for fiscal year 1997.
Hayes is widely recognized as being the company that commercialized the PC
modem in the early 1980's.  The Hayes Standard AT Command Set has become the de
facto industry standard for PC modems and along with the patented escape
sequence created the market requirements for "Hayes compatibility."

         Hayes markets its modem products under the Hayes ACCURA(TM), Hayes
OPTIMA(TM), Practical Peripherals(TM), and Cardinal(TM) brands.  The modem
products are sold through the distribution, value added reseller and mass
merchant channels.

         Due to demand for increased speed in delivery of information, modem
speeds have historically changed every 12 to 24 months.  In 1997, Hayes
introduced a series of new products that transmit information at 56Kbs.  Hayes
anticipates that the market will transition during 1998 to the 56Kbs speed from
the current 33.6Kbs standard.  In February 1998, the industry determined a
56Kbs standard referred to as V.90.  The standard is expected to be ratified
late 1998.  Hayes currently sells products utilizing the two primary 56Kbs
technologies offered in the market prior to the determination of the standard,
as well as products utilizing the V.90 standard.

BROADBAND PRODUCTS

         Recognizing the market's need for more information at faster speeds,
Hayes has launched significant activities to deliver its customers products at
speeds of multiples of those offered by current analog and ISDN products.
Hayes' efforts are focused on the ADSL and cable markets.

ADSL

         On June 6, 1997, Hayes announced that it had been selected by Alcatel
Bell N.V. ("Alcatel") to jointly develop, manufacture and market products and
equipment implementing ADSL technology.  These end-to-end ADSL solutions will
enable consumers, telecommuters and small business users to achieve affordable,
convenient, bandwith-efficient, high-speed access to the Internet and other
interactive services, such as corporate intranets.

         ADSL technology, which utilizes the existing telephone copper-wiring
infrastructure serving virtually all homes and businesses, allows customers to
interact with data networks, the Internet and associated services at speeds
more than 100 times faster than current 56Kbps modems.  In recent months,
Alcatel has signed contracts with Ameritech, Bell South, Pacific Bell,
Southwestern Bell, Singapore Telecom, Telia (Sweden) and others to provide its
1000 ADSL system.  Hayes believes it will benefit from the deployment of ADSL
products by these companies.

         Hayes is pursuing other opportunities utilizing ADSL technologies to
develop a strong market position in the emerging ADSL market. The Company
expects to begin shipping ADSL products in mid-1998.

Cable

         Management believes that the consumer's demand for higher speed
communications will result in significant demand for cable modems.  In 1996
Hayes launched a development and marketing effort with an Israeli cable modem
company.  In the fourth quarter of 1996 Hayes introduced its cable modem
products to the industry and began a number of successful cable modem trials.
Hayes began shipping cable modems in the second half of 1997, under its
ULTRA(TM) brand.

         On September 18, 1997, Hayes and Cisco Systems, Inc. ("Cisco") signed
a Collaboration Agreement whereby Hayes and Cisco agreed to promote Multimedia
Cable Network System ("MCNS") compliant cable modems and head end systems.  The
Collaboration Agreement contemplates joint development and marketing of such
products.

         On September 18, 1997, Cisco announced that Samsung Electronics Corp.,
Ltd. And Thomson Consumer Electronics had joined Cisco and Hayes in promoting
MCNS compliant cable modems.


                                                                          Page 3


                                                                                
<PAGE>   6

         Hayes is pursuing several cable modem opportunities in North America
including the request for proposal by TeleCommunications, Inc. (the "TCI RFP").
The TCI RFP is believed to be the largest single cable modem opportunity in
North America.  The Company recently announced retail distribution programs
with retailers such as Computer City to promote deployment of cable modems.
Hayes is also pursuing cable modem opportunities in China and Latin America.

ACCESS SYSTEMS

         The communications industry has seen tremendous growth in the area of
network connectivity.  As the number of telecommuters, traveling employees and
branch offices grow, the demand for fast, low-cost connectivity has grown.
Connectivity is enabled through client modems, modem pools and integrated
remote access devices.  Hayes is seeking to leverage its experience and
technology strengths in communications to provide a portfolio of products that
meet the market's needs.

         As a result of a prior supply agreement with Access Beyond and the
Merger, the Company markets a family of remote access servers including its
Century 2000 series, Century 9200 series and Century 9400 series products.
These products support the connectivity needs of the small business or branch
office.  They are fully-integrated remote access servers providing advanced
management software which enables easy configuration and network monitoring.
These products use a modular design for flexibility and ease of upgrade. In
addition to the remote access servers, the Company markets other network
products under the Access Beyond brand. These products include statistical
multiplexers, host access servers, and ethernet terminal servers.

         Hayes has a technology agreement with Microcom, Inc. ("Microcom")
under which Hayes and Microcom have agreed to develop end-to-end communication
solutions drawing from the technology in Microcom's ISP Porte Chassis and
Hayes' client and remote access server products.  According to terms of the
agreement, the two companies will explore product development, product branding
and co-marketing opportunities worldwide.

SUPPLIERS

         Hayes depends upon certain suppliers for its sole source for certain
components, including Rockwell and Lucent Technologies, Inc. for certain modem
chips used in most of Hayes' product.  In addition, Hayes utilizes two
subcontractors with operations in China to manufacture product for the Asia
Pacific and Europe markets.

PATENTS, COPYRIGHTS AND LICENSES

         Hayes' patent estate strategy is based upon three goals: (i) to
protect Hayes' technology and to enhance its commercial deployment, (ii) to
obtain cross licenses of the technology of others to optimize a royalty-free
access to new technology, and (iii) to generate income.  This strategy has
resulted in a significant patent estate consisting of more than 115 owned and
licensed patents, including internationally recognized patents, in the area of
data communications.

         Hayes is committed to a licensing program which defends the value of
its intellectual property and offers licenses to responsible third parties.  As
a result of Hayes' aggressive patent estate development program, many of Hayes'
competitors formed the Modem Patent Defense Group.  This group attempted to
refute the validity of the Hayes' patents, specifically the Heatherington '302
patent, U.S. patent #4549302 ("Heatherington Patent"), and to avoid payment of
royalty fees by filing suits against Hayes.  To date, Hayes has successfully
defended its patent estate, resulting in additional manufacturers signing
license agreements to use Hayes' patents.

         The Heatherington Patent has been Hayes' most valuable patent to date.
This patent enables the modem to be switched between data transmission mode and
command mode for configuring the modem.  The patent was issued in 1985 and is
valid until February 14, 2001.  The Heatherington Patent is licensed to
virtually every major modem manufacturer in the United States and is recognized
around the world as an industry standard for computer communications.  The
validity of the patent was upheld by the U.S. Federal Court and since the fall
of 1994 has been fully protected in the European Community.


                                                                          Page 4


                                                                                
<PAGE>   7

         Another significant patent is the AutoSync patent, U.S. patent
#4700358, which expires on October 13, 2004.  This patent is a sophisticated
asynchronous to synchronous converter which allows serial communication through
the asynchronous serial port.  Industry interest has been expressed in
implementing and licensing this technology.  Currently there are approximately
12 companies licensing this patent from Hayes.

         Hayes has other valuable license rights that were obtained through
cross-license agreements with key industry players, including AT&T Corporation,
3Com Corporation ("3Com"), Intel, Compaq, IBM Corporation, Racal Datacom and
Microcom.

         Hayes has current and pending patents with potential commercial value
in the area of data compression, multi- channel communication and various other
technologies related to data communications.

         The Company's credit facilities provide its lender collateralized
rights to Hayes' intellectual property.  Use of Hayes' intellectual property is
not adversely affected by this collateralization and the intellectual property
is being used in the manufacturing and distribution of Hayes' products.  Lender
approval is required prior to any material sale of Hayes' intellectual
property.

BACKLOG

         Hayes forecasts demand and builds products in order to fill expected
demand.  Customers generally expect delivery within one to two weeks and Hayes'
backlog of firm orders generally represents orders expected to be filled not
later than two months following the date of the order.  Management believes
that current backlog may not necessarily be indicative of future revenues.

COMPETITION

         The data communications industry is very competitive.  Product life
cycles are short with rapid improvements required in terms of product
performance, features and cost.  Hayes competes in a number of different
markets within the overall communications market.

Modem Business Market

         Hayes faces competition primarily from established companies such as
3Com, Microcom, Multitech, Racal Datacom and Diamond Multimedia, Inc.
("Diamond").  The primary basis of competition is brand recognition,
performance, features, quality, reliability, price, service and support.

Modem Consumer Market

         The retail modem market is expected to continue its consolidation.
The primary basis of competition is brand recognition and price.  3Com is the
most significant competitor in this market with several smaller competitors
competing at the very low price points.  A sample of these smaller competitors
include Golden Video Corporation ("GVC"), Boca Research, Inc., and Zoom
Telephonics, Inc.  The battle for retail shelf space is and will continue to be
fierce and brand recognition is and will continue to be a major benefit to
Hayes.

OEM Modem Market

         Hayes intends to make significant efforts to reenter the OEM modem
market which is the fastest growing segment of the analog modem market.  Low
cost, quality and responsiveness are critical to success in this market.  The
key competitors in this market are CIS Technology, Inc., GVC, 3Com and others.

Access Systems

         The access systems market is characterized by a large number of
participants, none of which have a dominant market position.  The market is
experiencing high growth and higher margins in comparison to modems.

                                                                          Page 5



                                                                                
<PAGE>   8

Companies such as 3Com, Shiva Corporation, Ascend Communications and General
Datacom compete in this market.

         Management believes that in addition to leveraging its strong brand
name, its products can be priced competitively which will enable Hayes to grow
its share of this market.  

Broadband

         ADSL is an emerging market with no competitor having dominant market
position.  Many of the network product and modem companies are likely to
introduce products into this market.  In addition, major telecommunications
companies such as Alcatel are expected to have significant presence in the ADSL
market as it matures.

         The cable market is also an emerging market.  Cable equipment
companies such as Scientific Atlanta, Inc. and Nextlevel Systems, Inc. are
expected to capture a share of this market.  In addition, management believes
that modem companies such as 3Com and Bay Networks, Inc. will offer products in
this market.  Management expects competition to intensify as cable modem
products gain acceptance.

International

         Hayes' products are sold internationally in more than 40 countries.
Some of the U.S. based competitors are present in Hayes' international market
but competition is also present from smaller local modem and access systems
suppliers.

SALES

AMERICAS REGION

North America

         Hayes sells its products directly to high-volume computer superstores,
mail order resellers and mass merchants as well as through the two-tiered PC
distribution channel that includes distributors, large national corporate
resellers and aggregators.  In the two-tiered distribution model, distributors
and national corporate resellers provide an inventory, logistics, and credit
function to smaller resellers such as computer chains, company-owned locations
and value-added resellers.

         The sales strategy for Hayes branded products is to retain a channel
"push" sales organization (reseller, marketing and telephone) ensuring channel
support and appropriate field inventory levels.  The sales organization is
structured to focus on the Hayes, Practical Peripherals and Cardinal brands and
each respective product categories and product lines.

         Hayes' sales force consists of the Field Sales Group and the National
Account Group.  The Field Sales Group maintains relationships with the
corporate headquarters of Hayes' channel partners as well as the individual
reseller locations that sell to end users.  The Field Sales Group works with
the resellers to maintain adequate inventory of Hayes' products and to develop
programs that promote Hayes products.

         The National Account Group calls on large corporate customers and
directly markets Hayes' products to these large sophisticated end users.  This
group is responsible for creating and maintaining demand in Fortune 1000
companies for Hayes' technologies.  Hayes also maintains a sales office in
Gaithersburg, Maryland to market to the Federal Government and maintains
dedicated resources within its National Account Group to stimulate sales to
state and local governments.


                                                                          Page 6




                                                                                
<PAGE>   9

Latin America

         Hayes has recently launched an initiative in Brazil to serve Brazil
and the Latin American region.  Business is presently conducted directly with
large end users, OEMs and through distributors for other customers.

ASIA PACIFIC REGION

         Hayes' sales strategy in the Asia Pacific region is similar to its
sales strategy in North America.  Hayes operates sales, marketing and service
subsidiaries in China, Hong Kong and Australia.  Relationships are developed
with key distributors in each of the major Asia Pacific region countries.

EUROPE REGION

         Hayes' European sales, marketing and service efforts are headquartered
in the United Kingdom.  Offices are also maintained in France, Denmark, and
Germany.  Strategic partners are identified in major markets to distribute
Hayes' products.

REVENUES FROM EXPORT SALES

         Hayes revenues from export sales to its principal foreign markets were
immaterial for the periods presented.  

MARKETING
 
         Hayes' marketing activities focus on developing brand recognition in 
key market segments and geographic markets, as the underlying basis for cost
effective promotion of its products.

Public Relations

         Hayes has focused its public relations activities on establishing
strong relationships with trade publications, reviewers and columnists.  Hayes'
products have been consistently recognized for performance, quality, service
and support (i.e., Government Computer News, Computer Shopper, PC Week, Mobile
Office, PC Magazine, Computerworld).  Hayes has pursued a proactive posture in
public affairs, taking a prominent role in standard setting committee (ITU,
ANSI) and public policy organizations (AOP, GHTA and CompTIA).

Advertising, Packaging and Documentation

         Over the years, Hayes has developed an in-house expertise to create
advertising that has consistently scored well in advertising readership
studies.  Hayes has been recognized by winning coveted awards for the quality
of its documentation and packaging, which is also developed by Hayes in-house.

Channel and Infrastructure Activities

         Hayes has established an effective channel marketing program which
allows the sales force to consistently execute on tactical promotions through
the entire channel spectrum.  Hayes was most recently successful in developing
new mail order and mass merchant distribution channels.  Hayes also has had
success through its infrastructure program in seeding its new products with
influential user groups of early adopters.  In addition, customers can purchase
Hayes products over the worldwide web via ordering and fulfillment programs
recently implemented by Hayes.

CUSTOMER SUPPORT, SERVICE AND WARRANTY

         Hayes strives to provide users of its products with the highest
quality technical support and customer service, dedicating more than 50
professionals processing more than 60,000 incoming calls a month.  Hayes


                                                                          Page 7




                                                                                
<PAGE>   10

constantly surveys its user base with regard to customer satisfaction and it
believes it consistently performs well in comparison to its competitors in the
area of support and service.

         Hayes offers a standard two-year warranty which permits customers to
return any product for repair or replacement if the product does not perform as
warranted.  In the U.S. and Canada only, Hayes also offers its customers the
option of an additional three-year warranty upon completion of a registration
card within 90 days of purchase.  Some of the Practical Peripheral modems
previously sold have a lifetime warranty.  Hayes to date has not encountered
material warranty claims or liabilities.

RESEARCH AND DEVELOPMENT

         Hayes focuses its research and development ("R&D") efforts on hardware
and firmware system design, integration and testing for standalone and board
level data, fax and voice modems, modem pools, remote access servers and
broadband technologies for high speed communications.  Additional R&D
activities include access systems and software products, object oriented
programming and digital signal processing technologies.  Specialized knowledge
and skills in the areas of electromagnetic compatibility ("EMC"), agency
approvals, communications standards and product integration are applied to
ensure timely product delivery.  The Company utilizes computer aided design
systems for three dimensional mechanical design and is upgrading its computer
aided engineering tools to improve the engineering process and strengthen
applications specific integrated circuit design capabilities.

         Product development cycles typically range from three to twelve
months.  Project duration of fifteen to eighteen months are common for new
access systems and new technology platforms.  Engineering strategies employed
to reduce product costs and time to market include focused application of
resources, simulation, standardization, on-going product and process value
engineering, simplification, automation and reduction of the number of
development cycles.  Hayes expensed approximately $10.7 million, $9.6 million
and $11.8 million for the fiscal year ending September 30, 1995, December 31,
1996 and January 3, 1998, respectively for research and development.

         As of January 3, 1998 the Company estimates that the remaining costs
in connection with the completion of outstanding acquired research and
development projects are less than $6.0 million.  Such costs are expected to be
incurred primarily over the next two years and to include labor costs for
design, prototype development and testing.  As a result, the Company expects
research and development costs to increase in fiscal 1998.

ENVIRONMENTAL MATTERS

         Hayes' compliance with federal, state and local environmental laws has
had no material effect upon Hayes' capital expenditures, earnings or
competitive position.

EMPLOYEES

         Hayes employed approximately 651 employees and 117 temporary employees
as of January 3, 1998.  Hayes management believes that its future success will
depend largely on its ability to retain certain key personnel and to recruit
and retain additional highly skilled employees.  Hayes has experienced no work
stoppages and believes that its employee relations are satisfactory.

BUSINESS RISKS

         In addition to the other information in this Form 10-K, readers
should carefully consider the following important factors that in some cases
have affected, and in the future could affect, the Company's actual performance
and results and could cause the Company's actual results of operations to
differ materially from those expressed in any of the forward-looking statements
made by, or on behalf of, the Company.


                                                                         Page 8




                                                                                
<PAGE>   11

ABSENCE OF PROFITABLE OPERATIONS

         The Company has not been profitable in the last four years. Due to the
factors described below, there can be no assurance that the Company will
achieve its objectives and attain profitability.

TECHNOLOGICAL CHANGES

         The market for networking and modem products is subject to rapid
technological change, evolving industry standards and frequent new product
introductions and, therefore requires a high level of expenditures for research
and development.  There can be no assurance that customer demand for the
Company's products will grow at the rate expected by the Company or that the
Company will be successful in developing and manufacturing new products that
respond to customer demand.

COMPETITION

         The networking and modem markets are very competitive. There are
numerous companies competing in various segments of these markets, many of the
Company's competitors have greater market, technology and financial resources
than those available to the Company. There can be no assurance that the Company
will be able to compete successfully with future and existing competitors.

INTERNATIONAL SALES

         A significant portion of the Company's sales are in international
markets. As a result, the Company's operating results are subject to risks
inherent in international sales, including tariffs or other barriers,
difficulties in staffing and managing international operations, fluctuations in
foreign currency exchange rates, compliance with international regulations,
approval and market requirements, and the volatility of international economic
conditions.

PRODUCT RETURNS AND PRICE PROTECTION

         Like other manufacturers of computer products, the Company is exposed
to the risk of product returns from wholesale distributors, resellers and
retailers, either through contractual stock rotation privileges or as a result
of the Company's interest in assisting customers in balancing inventories.
Although the Company attempts to monitor and manage the volume of sales to
wholesale distributors and retailers, large shipments in anticipation of sales
by wholesale distributors and retailers could lead to substantial overstocking
and higher than normal returns. Moreover, the risk of product returns may
increase if demand for the Company's products declines. When the Company
reduces prices, the Company credits their respective wholesale distributors and
retailers for the difference between the purchase price of products remaining
in their inventory and the reduced price for such products on terms negotiated
with the Company.  To the extent credits due distributors and retailers are in
excess of amounts accrued by the Company, a material adverse effect on the
operation results of the Company could occur.

DEPENDENCE ON SUPPLIERS

         Material and components for the Company's products are purchased from
outside suppliers. While most components are available from several suppliers,
a few are provided from sole-source vendors. The Company believes that in most
cases alternative sources of supply could be obtained within a reasonable time
period; however, an interruption in the supply of such components could have a
temporary adverse effect on the Company's operations. There can be no assurance
that severe shortages of components will not occur in the future which could
increase the cost or delay the shipment of products and have a material adverse
effect on the Company's operating results.





                                                                         Page 9




                                                                                
<PAGE>   12
SALES CHANNEL RISKS

         The Company sells its products primarily through national, regional
and international wholesale distributors, national corporate resellers,
computer superstores and mail order. Sales to wholesale distributors accounted
for a significant share of Hayes net sales in fiscal 1997. The personal
computer distribution industry has been characterized by rapid change,
including consolidations and financial difficulties of wholesale distributors
and the emergence of alternative distribution channels.

         The Company is dependent upon the continued viability and financial
stability of its wholesale distributors.  The loss or ineffectiveness of any
Hayes' largest wholesale distributors or a number of its smaller wholesale
distributors could have a material adverse effect on the Company's operating
results. In addition, an increasing number of vendors are competing for access
to wholesale distributors which could adversely affect the Company's ability to
maintain existing relationships with its wholesale distributors or could
negatively impact sales to such distributors.

         The Company is dependent on the continued viability and financial
stability of its national resellers. The loss or ineffectiveness of any of the
Company's largest national resellers or a number of its smaller national
resellers could have a material adverse effect on the Company's operating
results.

         Due to increased competition for limited shelf space, retailers are
increasingly in a better position to negotiate favorable terms of sale,
including price discounts and product return policies. There can be no
assurance that the Company will be able to sustain or increase its sales to
retailers, which could have a material adverse effect on the Company's
operating results.

         The OEM modem market has grown to approximately 50% of the overall
modem market. Hayes has not participated substantially in the OEM modem market
for the last three years and the Company can give no assurance that it will be
able to successfully penetrate this market.

ITEM 2. PROPERTIES

         Hayes' executive offices are located in Norcross, Georgia in leased
facilities. Hayes also has manufacturing and distribution facilities at the
same location.  The manufacturing facility has five surface mount lines and
occupies approximately 50,000 square feet.  The leases between Hayes and Essex
Capital are for 172,342 square feet and cover both the executive offices and
Hayes' manufacturing and distribution facilities.  The leases expire between
December 31, 1999 and September 30, 2000.

         The Company leases a 54,874 square foot facility in Gaithersburg,
Maryland which houses its government sales activities and serves as the
development center for its access systems products.  Approximately 50% of the
facility is subleased.  The lease on this facility expires on September 30,
1999.

         The Company also leases a 44,403 square foot facility in Carlstadt, 
New Jersey which is also a development center for its access system products.  A
substantial portion of this facility is subleased.  The lease on this facility
expires in September 2001.

         In addition to the above leases, Hayes leases sales and marketing
facilities in China, Hong Kong, Australia, United Kingdom, France and Denmark.

         Hayes believes its properties are adequate for its needs for the
foreseeable future.

ITEM 3. LEGAL PROCEEDINGS

         On March 22, 1996, Hayes filed a Complaint for Declaratory Judgment
and Damages for breach of fiduciary duties in the Superior Court of Fulton
County, Atlanta, Georgia against three of Hayes' former vice presidents, Gary
Franza, John Stuckey and Mikhail Drabkin.  In the Complaint, Hayes claims $5.0
million in minimum damages against the defendants, jointly and severally, plus
punitive damages.  The Complaint also seeks a declaratory judgment that a
rescission by the defendants of an earlier partial release executed by them is


                                                                        Page 10




                                                                                
<PAGE>   13

enforceable and for the recovery of attorneys' fees.  All three defendants have
filed counterclaims against Hayes and Dennis C. Hayes individually seeking
total contract damages against Hayes and Dennis C. Hayes of approximately
$450,000 and specific performance of claims for stock options for 292,012
shares of stock under certain option agreements.  Two of the three defendants
assert libel claims and allege compensatory damages resulting therefrom in the
total amount of $10.0 million and punitive damages in the total amount of $10.0
million.  All three defendants seek recovery of their attorney's fees and
expenses of litigation.  Hayes' management believes that the likelihood of a
material adverse effect on the financial condition on operations of the Company
in the amount of damages claimed by the plaintiffs is remote.  Hayes' insurer
has undertaken coverage of the libel and slander claims alleged in the
counterclaim against the Company.  Other than the litigation matter described
above, Hayes believes that there are no other material legal proceedings to
which Hayes is a party or of which any of its properties are subject; nor are
there material legal proceedings known to Hayes to be contemplated by any
governmental authority; nor are there material legal proceedings known to
Hayes, pending or contemplated, in which any director, officer or affiliate or
any principal security holder of Hayes, or any associate of any of the
foregoing, is a party or has any interest adverse to Hayes.

</TABLE>

         As of March 16, 1998, there were 791 record holders of the Company's
Common Stock.

         The Company has never paid cash dividends.  It is the Company's
present policy to retain earnings for use in the Company's business.
Accordingly, the Company does not anticipate that cash dividends will be paid
in the foreseeable future.  The Company's credit facilities limit the Company's
ability to declare or pay dividends other than in the form of stock.

         Holders of the Series A Preferred Stock will be entitled to receive,
as and when declared by the Board of Directors, cumulative compounding
dividends at the rate of 10% per annum of the original issue price per share of
the Series A Preferred Stock.  Such dividends are to be paid in cash upon
redemption, or in additional shares of Common Stock upon conversion of the
Series A Preferred Stock.

         Holders of the 6% Cumulative Convertible Preferred Stock are entitled
to receive a dividend of 6% per annum payable December 31 of each year.  Such
dividend is payable in cash, Common Stock or additional shares of Cumulative
Convertible Preferred Stock at the Company's option.


                                                                         Page 13

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

GENERAL BUSINESS DEVELOPMENTS

         Hayes is comprised of three business units: the Modem Products
business, the Access Systems business and the Broadband Products business.  The
Modem Products business designs, manufactures and markets analog and ISDN modem
products.  The Modem Products business distributes its products under the
Optima, Accura, Practical Peripherals, and Cardinal brands.  The Access Systems
business designs and markets modem pool and remote access server products.
These products are distributed under the Century brand.  The Broadband Products
business designs and markets ADSL and cable modem products and was formed in
June 1997.  The Broadband Products business markets its products under the
Ultra brand.

         On December 30, 1997, the Company (formerly known as Access
Beyond) merged with Hayes Microcomputer in a reverse triangular merger. Since
the Hayes Microcomputer shareholders received a substantial majority of the
shares of stock of the Company, the historical financial statements of the
surviving company for the periods prior to the Merger are those of Hayes
Microcomputer rather than those of Access Beyond. The former business of Access
Beyond will become a part of the Access Systems business unit. Because the
Merger occurred in the last week of the Company's fiscal year, the operations
of Access Beyond did not materially impact the Company's operating results. As
described further herein, the Company recorded significant restructuring and
acquired in process research and development charges in connection with the
Merger.

         On October 1, 1995, Hayes changed its year end from September 30 to
December 31, and effective with fiscal year 1997 the Company changed its year
end to the Saturday closest to December 31.

LIQUIDITY AND CAPITAL RESOURCES

         General.  Hayes' primary capital requirements are for working capital,
acquisitions and other capital expenditures.  Hayes has historically met its
capital requirements through a combination of equity transactions, cash flow
from operations, bank lines of credit and credit terms from suppliers.

         Cash Flows.  Cash and cash equivalents increased by approximately $9.5
million to $15.2 million at January 3, 1998 as compared to $5.7 million at
December 31, 1996.  Cash and cash equivalent increased by $0.5 million at
December 31, 1996 from $5.2 million at September 30, 1995. Cash and cash
equivalents decreased by $3.1 million at September 30, 1995 as compared to
September 30, 1994.  The increase in cash at January 3, 1998 versus December
31,1996 is due to the Company's placement of $35.0 million in 6% Cumulative
convertible Preferred Stock on December 31, 1997.  The increase in cash in
fiscal 1996 resulted from implementation of the Plan and reduction in
restricted cash.  The decrease in fiscal 1995 resulted primarily from the
increase in restricted cash as a result of Hayes' debtor-in-possession
financing with General Electric Capital Corporation ("GECC").

         Cash used in operations was $20.3 million and $41.1 million in the
fiscal years 1997 and 1996, respectively.  Cash usage in fiscal year of 1997
was caused primarily by the Company's operating losses and higher receivables
due to reduction in prompt payment discounts.  Cash used in operations was
$41.1 million in fiscal 1996 due to the implementation of the Plan, which
included payments of approximately $44.6 million to pre-petition claimants, and
a net loss of $13.2 million.  Cash generated by operations was approximately
$1.5 million in fiscal 1995 and resulted from a net loss of approximately $14.4
million which was more than offset by non-cash depreciation and amortization
and reduced working capital investment.

         Cash provided by investment activities was approximately $0.1 million
in fiscal year 1997 due to capital expenditures which were largely offset by
gains on sales of investments.  Cash from investment activities in fiscal 1996
was due to the sale of real estate, investments and equipment and a reduction
in restricted cash partially offset by capital expenditures.  Cash used in
investment activities was $1.5 million in fiscal 1995 primarily due to capital
investments and an increase in restricted cash.


                                                                         Page 15


                                                                                
<PAGE>   18


         Cash provided from financing activities was approximately $30.6
million for fiscal 1997 largely due to the issuance of the Series A Preferred
Stock and the 6% Cumulative Convertible Preferred Stock less debt repayments.
Cash provided from financing activities was $29.5 million in fiscal 1996 due to
the implementation of the Plan. Cash used in financing activities in fiscal 1995
was $3.0 million and was the result of a net increase in borrowings.

         As of January 3, 1998 the Company estimates that the remaining costs
in connection with the completion of outstanding acquired research and
development projects are less than $6.0 million.  Such costs are expected to be
incurred primarily over the next two years and to include labor costs for
design, prototype development and testing.  As a result, the Company expects
research and development costs to increase in fiscal 1998.

         At January 3, 1998, Hayes' principal sources of liquidity included
cash and cash equivalents and its credit facilities with CIT (the "CIT
Facility").  The CIT Facility was replaced on February 20, 1998 by a credit
facility with the Commercial Funding Division of NationsCredit
("NationsCredit").  The NationsCredit facility consists of two term loans and a
revolving loan which provide for maximum borrowings of $42.5 million.   The
revolving loan provides for financing based upon eligible receivables and
inventory.  The term loans are based upon appraised values of equipment and
intangibles.  The term loans and the revolving loans bear interest at prime
plus 0.75% (9.25% at February 20, 1998).  The CIT Facility was similarly
comprised and bore interest at 1.875% over prime (10.375% at January 3, 1998.)

         Management believes its cash and cash equivalents and its credit
facilities, will be sufficient to satisfy operating cash and capital
expenditure requirements for at least the next twelve months.

INFLATION

         Hayes believes that inflation has not had a material impact on its
operating results and does not expect inflation to have a material impact on
its operating results in the foreseeable future.

</TABLE>

         Net revenues in fiscal 1997 decreased by $57.8 million, or 22.5%, from
the same period in 1996 due to lower revenues in both the Modem Products and
Access Systems businesses.  The decrease in net revenues was largely
attributable to Hayes' introduction of modems with 56Kbs speeds.  In the third
quarter of fiscal 1996, Rockwell and 3 Com announced the introduction of modem
technology that would permit data to be transmitted on analog phone lines at
56Kbs.  These announcements were followed by announcements by most modem
providers, including Hayes, indicating product availability in the first and
second quarters of 1997.  As a result of these announcements and commentary
from various industry analysts, management believed that its channel partners
assumed that modem customers would move quickly to 56Kbs modems and away from
the then industry standard 33.6Kbs modems.  Consequently, Hayes' channel
partners significantly reduced orders for 33.6Kbs products and substantially
reduced channel inventories of such products in the first quarter.  Instead of
placing orders for 33.6Kbs products, Hayes' channel partners began placing
orders for Hayes' 56Kbs products.  Due to the lack of availability of 56Kbs
modem chips from its suppliers, Hayes was unable to fill many of these orders
and backlog rose to $10.5 million at March 31, 1997 from $4.6 million at
December 31, 1996.


                                                                         Page 16


                                                                                
<PAGE>   19

         In the second quarter of 1997, Hayes began to fill its channel
partners demand for 56Kbs product.  Management believes that during this period
its channel partners realized that customer demand was weighted heavily toward
33.6Kbs products and the market had not yet accepted 56Kbs products.  As a
result, Hayes' channel partners began to place significant orders for 33.6Kbs
products.  Hayes had converted much of its manufacturing schedule to 56Kbs
products and was therefore unable to meet much of its channel partners' demand
for 33.6Kbs product during the second quarter.  Although second quarter 1997
revenues increased 42.2% from the first quarter of 1997 to $55.7 million at
June 1997, backlog grew to $20.9 million at June 30, 1997.

         In the second half of 1997, market demand continued to be unstable and
Hayes experienced 33.6Kbs chip shortages from its vendors and experienced
quality problems with certain 33.6Kbs chips provided by a supplier. These
factors limited shipments and disrupted supply to certain customers. In
addition, continued uncertainty about the industry's determination of a
standard suppressed demand.  Backlog declined to $10.6 million at January 3,
1998.

         Gross profit as a percentage of net revenues declined to 22.5% in
fiscal 1997 from 23.9% in fiscal 1996 due to unfavorable manufacturing
variances caused by disruption to manufacturing schedules and lower average
selling prices for 33.6Kbs products resulting from the introduction of 56Kbs
products.  In addition, the Company recorded additional inventory reserves in
the fourth quarter.

         Selling, general and administrative expenses decreased by $5.4 million
in fiscal 1997 from the comparable period in 1996.  Such expenses represented
28.2% of revenue in fiscal 1997 compared to 24.0% in fiscal 1996.  Hayes
reduced operating expenditures in anticipation of lower revenues in fiscal
1997, but expenses as a percent of revenue were higher due to such lower
revenues.  General and administration expenses for fiscal 1997 include $1.3
million in bonus and change of control payments in connection with the Merger.

         Research and development expense increased to $11.8 million from $9.6
million in fiscal 1997 compared to fiscal 1996 as a result of increased
development expenses related to new products for the access systems and
broadband markets.

         In connection with the Merger, the Company took a charge of $55.0
million related to acquired in-process research and development.  In addition
the Company recorded $5.8 million in restructuring charges related to cost of
severance, facility closures and asset write-offs.

             In fiscal 1997, the Company recognized a $4.1 million gain from
the sale of stock in a French software Company and other income increased $1.1
million over 1996 due to increased royalty payments.  Hayes also recognized a
gain in fiscal 1996 of $8.2 million from the sale of certain parcels of real
estate.

         Interest expense was $0.6 million lower in fiscal 1997 compared to
fiscal 1996.  The interest expense in 1996 included interest at 12%, which was
payable on most of the pre-petition claims.  These claims were paid in full in
April of 1996.

              The effective tax rate was 0.0% in fiscal 1997 compared to 3.0% in
fiscal 1996. The effective tax rate was significantly impacted by the
Company's losses and the recognition of valuation allowances on its deferred
tax assets.

         Hayes reported a net loss applicable to common shares of $84.6 million
for fiscal 1997 and net loss of $13.2 million for fiscal 1996.  On a per share
basis, net loss was $(10.80) and net loss was $(1.63) in fiscal 1997 and 1996,
respectively.

</TABLE>

         In fiscal 1996, Hayes reported net sales of approximately $257.5
million, a decrease of 4.3% from fiscal 1995.  Modem Products business net
revenues decreased 5.7% to $245.4 million in fiscal 1996.  This decrease
resulted from price erosion in the Company's 14.4Kbs and 28.8Kbs modem
products.  Access Systems business net revenues increased 35.7% in fiscal 1996
to $12.0 million due to growth in Century product sales.

         Gross profit, as a percentage of net sales, remained constant at 23.9%
in 1996 and 1995.  Although average sales prices declined in fiscal 1996 versus
fiscal year 1995, improved product designs and lower manufacturing and material
costs enabled Hayes to maintain its gross profit margins.

         Selling, general and administrative expenses, excluding restructuring
charges and amortization and write-off of intangibles, increased by
approximately $6.1 million in fiscal 1996 and rose as a percentage of revenue
to 24.0% versus 20.7% in fiscal 1995.  The primary factors in the increase were
higher marketing expenses resulting from Hayes' sponsorship of a NASCAR racing
team at a cost of $3.8 million, higher marketing expenses and recruiting and
relocation expenses due to the employment of a new management team as Hayes
emerged from Chapter 11, partially offset by lower administrative expenses.

         Research and development expense declined $1.1 million in 1996
compared to 1995 due to management's curtailment of expenditures in the first
half of 1996 as a result of the Chapter 11 proceedings.

         Interest expense decreased 23.5% or approximately $1.5 million in
fiscal 1996 as compared to fiscal 1995 as a result of the $35.0 million capital
investment made in Hayes, the sale of certain parcels of real estate, and a new
borrowing arrangement, all of which were part of the Plan by which Hayes
emerged from Chapter 11.  The implementation of the Plan enabled Hayes to pay
pre-petition claims which generally accrued interest at 12%.

         In fiscal 1996, Hayes recognized a gain of approximately $0.7 million
on the sale of stock of a public company which it had previously received as
settlement of an intellectual property dispute.  Hayes also recognized a gain
of approximately $8.2 million on the sale of certain parcels of real estate it
had previously acquired for development as a corporate campus.

         Other income consists primarily of insert fees from third parties for
the inclusion of their software and related promotional materials in Hayes'
products and intellectual property license fees.  Other income declined by
approximately $1.9 million or 45.2% in fiscal 1996 from approximately $4.2
million in fiscal 1995.  The decline resulted from a reduction in license fees
from Rockwell.  In July 1995, Hayes and Rockwell entered into an agreement in
which, among other things, Rockwell agreed to supply Hayes modem chips and
Hayes agreed to waive license fees from the date of the agreement through
December 31, 1996 (the "Rockwell Agreement").

         The effective tax rate was 3.0% in 1996 compared to 6.1% in fiscal
1995. The effective tax rate was significantly impacted by the Company's
losses, nondeductible Chapter 11 expenses and the recognition of valuation
allowances on its deferred tax assets.


                                                                         Page 18


                                                                                
<PAGE>   21

         Hayes reported a net loss of $13.2 million for fiscal 1996 and a net
loss of $14.4 million for fiscal 1995.  On a per share basis, net loss was
$(1.63) for fiscal 1996 and $(1.66) for fiscal 1995, respectively.


YEAR 2000

         The Company has assessed the impact of the year 2000 issue and
believes that the costs to upgrade its information and operating systems to
address this issue are not material.  In 1997, the Company commenced efforts to
replace its information systems with software from Oracle Corporation which is
Year 2000 compliant.  These efforts are expected to be completed in fiscal
1998.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of
Hayes Corporation and Subsidiaries

  We have audited the accompanying consolidated balance sheets of Hayes
Corporation and subsidiaries as of December 31, 1996 and January 3, 1998 and the
related consolidated statements of operations, stockholders' equity (deficit),
and cash flows for the year ended September 30, 1995, the three months ended
December 31, 1995, and the years ended December 31, 1996 and January 3, 1998.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Hayes
Corporation and subsidiaries as of December 31, 1996 and January 3, 1998 the
results of their operations and their cash flows for the year ended September
30, 1995, the three months ended December 31, 1995, and the years ended December
31, 1996 and January 3, 1998 in conformity with generally accepted accounting
principles.

                       HAYES CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  NATURE OF BUSINESS

         Hayes Corporation, along with its wholly owned subsidiaries
(collectively, the "Company"), is engaged in the development, production and
marketing of telecommunications equipment and software and sells primarily to
personal computer and peripheral distributors and resellers.

ACCESS BEYOND, INC. MERGER

         On December 30, 1997 Access Beyond, Inc. ("Access Beyond") and Hayes
Microcomputer Products, Inc. ("Hayes Microcomputer") completed a reverse
triangular merger (the "Merger") whereby Access Beyond acquired Hayes
Microcomputer.  Immediately after the Merger, Access Beyond changed its name to
Hayes Corporation ("Hayes"). In the Merger, shareholders of Hayes Microcomputer
received approximately 79% of the outstanding common stock of Access Beyond,
without giving effect to the 6% Cumulative Preferred Sock and the stock
warrants and options of the two companies. Since the Hayes Microcomputer
shareholders received a substantial majority of the shares of common stock of
the newly named Hayes, the transaction was treated as a reverse acquisition by
Hayes Microcomputer for accounting purposes. As a result the historical
financial statements of Hayes for the periods prior to the merger are those of
Hayes Microcomputer rather than those of Access Beyond.

HAYES MICROCOMPUTER REORGANIZATION

         On November 15, 1994, Hayes Microcomputer filed a petition for relief
under Chapter 11 of the United States Bankruptcy Code due to its inability to
pay its debts on a current basis. Under Chapter 11, certain claims against the
debtor in existence prior to the filing of the petition for relief under the
federal bankruptcy laws were stayed while the Debtor continued business as a
debtor-in-possession ("DIP").

         Hayes Microcomputer filed amended and restated plans of
reorganization, the most recent dated February 9, 1996 (the "Plan"). The Plan
was confirmed by the U.S. Bankruptcy Court on March 8, 1996 and became
effective on April 16, 1996. From November 1994 through April 1996, Hayes
Microcomputer operated as the DIP. The Plan provided for the payment in full of
all prepetition creditors on the effective date, plus interest on such
creditors' claims, except where such creditors have agreed to accept payments
over a period of time. Funding of the plan was provided through three major
sources. First, pursuant to an agreement and plan of merger dated April 12,
1996 (the "Agreement") and entered into by and between Rinzai Limited ("ACMA"),
Kaifa Technology (H.K.) Limited, Rolling Profit Holdings, Ltd., Lao Hotel
(H.K.), Limited, Saliendra Pte Ltd., and S.P. Quek Investments Pte. Ltd.
(collectively, the "Investors"), certain subsidiaries were created by the
investors which collectively contributed $35.0 million and merged with Hayes
Microcomputer. The Investors received preferred stock representing a 49 percent
voting interest in Hayes Microcomputer. Second, Hayes Microcomputer entered
into an agreement with The CIT Group/Credit Finance, Inc. ("CIT") to borrow up
to a total of $64.5 million through three separate debt instruments
collateralized by Hayes Microcomputer's intellectual property, certain
equipment, and accounts receivable and inventory balances. Third, pursuant to
the Plan, Hayes Microcomputer sold certain parcels of real property.  On
October 9, 1997 Hayes Microcomputer received the final decree bringing its
Chapter 11 case to a close.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

         The consolidated financial statements include the accounts of Hayes
and its wholly owned subsidiaries. All material intercompany balances and
transactions have been eliminated in consolidation. The Company's investments
in 20 to 50 percent owned companies in which it has the ability to exercise
significant influence over operating and financial policies are accounted for
on the equity method. Accordingly, the Company's share of the earnings of these
companies and any realized gains and losses are included in the





                                      F-6
<PAGE>   36

consolidated statements of operations. Investments in other companies are
carried at cost. The cost of securities sold is based on the specific
identification method.

         Effective January 3, 1998, the Company changed its year-end to the
Saturday closest to December 31. Separate financial information for the three
day transition period is not provided since there was no activity. During 1996,
the Company changed its year-end from September 30 to December 31. Certain
reclassifications have been made to prior period financial statements in order
to conform to the 1997 presentation.


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 at the
date of the financial statements, as well as the reported amounts of revenues
and expenses during the reporting period. Actual results could differ from
these estimates.


Cash and Cash Equivalents and Restricted Cash

         The Company considers all highly liquid investments with an original
maturity of three months or less when purchased to be cash equivalents.
Restricted cash at  January 3, 1998 related to funds escrowed for letters of
credit and at December 31, 1996 related to  Bankruptcy Court mandated escrowed
funds.

Inventories

         Inventories are stated at the lower of cost (first-in, first-out) or
market and include labor and related manufacturing overhead. Market with
respect to raw materials is replacement cost and for work in process and
finished goods is net realizable value. Inventories are presented net of
reserves for obsolescence.

Property and Equipment

         Property and equipment, including certain equipment acquired under
capital leases, are stated at cost less accumulated depreciation and
amortization. Depreciation is calculated for financial reporting purposes using
the straight-line method based on the estimated useful life of the assets
(three to five years). Leasehold improvements are depreciated over the shorter
of the lease term or useful life and assets acquired under capital leases are
amortized over the term of the underlying lease.

         Maintenance and repairs are charged to expense as incurred. Upon sale,
retirement or other disposition of these assets, the cost and the related
accumulated depreciation are removed from the respective accounts and any gain
or loss on the disposition is included in the consolidated statements of
operations.

Computer Software Costs

         In accordance with Statement of Financial Accounting Standards No. 86,
"Accounting for the Costs of Computer Software to Be Sold, Leased, or Otherwise
Marketed," the Company capitalizes costs incurred for the development of
computer software to be sold. Costs are capitalized upon the establishment of
technical feasibility of the product.  Capitalized costs are being amortized
based on current and future projected revenues for each product with an annual
minimum equal to the straight-line amortization over the five year estimated
economic useful life of the product.

Intangibles and Other Long-Term Assets

         The Company evaluates the recoverability of all long-lived assets
including related intangible assets and goodwill based upon a comparison of
discounted estimated future cash flows from the related operations with the
then corresponding carrying values of those assets.





                                      F-7
<PAGE>   37

         Intangible assets consist principally of purchased software and
goodwill which is being amortized using the straight-line method over five
years and five to ten years, respectively. Accumulated amortization was $12.2
million and $4.7 million at December 31, 1996 and at January 3, 1998,
respectively.

Revenue Recognition

         The Company's policy is to record revenue upon shipment of related
goods to customers. Sales to certain distributors are under terms which allow
for those distributors to receive price protection based on future price
reductions. Some sales made to distributors allow limited rights of return. The
Company provides an allowance for returns and price reductions based on
historical experience.

Income Taxes

         Income taxes have been provided using the asset and liability method
in accordance with Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes". Under SFAS 109, deferred tax liabilities and
assets are determined based on temporary differences between the bases of
certain assets and liabilities for income tax and financial reporting purposes.
The differences are primarily attributable to reserves on inventory, accounts
receivable, net operating loss carry forwards and reserves for warranty claims.
Future tax benefits, such as net operating loss carry forwards, are recognized
to the extent that realization of such benefits is more likely than not. The
effect of a change in the valuation allowance that results from a change in
circumstances that causes a change in judgment about the realizability of the
related deferred tax asset in future years would be included in income in that
period.

Advertising

         All advertising costs are expensed when incurred. Advertising expenses
were approximately $9.9 million, $3.4 million, $18.0 million  and $15.2 million
for the years ended September 30, 1995, the three months ended December 31,
1995, and the years ended December 31, 1996 and  January 3, 1998, respectively.

Foreign Currency Translation

         The financial statements of subsidiaries of the Company outside the
United States are measured using the local currency as the functional currency.
Translation adjustments result from the process of translating those
subsidiaries' financial statements from functional currency into U.S. dollars.
Translation adjustments are reported separately and accumulated in a separate
component of equity. Assets and liabilities of these subsidiaries are
translated at the rates of exchange at the balance sheet dates. Income and
expense items are translated at monthly weighted average rates.

Future Adoption of Recently Issued Accounting Standards

         The Financial Accounting Standards Board has issued Statement of
Financial Accounting Standards No. 131, "Disclosures About Segments of an
Enterprise and Related Information" ("SFAS 131") and No. 130, "Reporting
Comprehensive Income" ("SFAS 130"). SFAS 131 specifies revised guidelines for
determining an entity's operating segments and the type and level of financial
information to be disclosed. SFAS 130 establishes standards for reporting and
display of comprehensive income and its components (revenues, expenses, gains
and losses) in a full set of general-purpose financial statements. These
standards are effective for periods beginning after December 15, 1997.

         The Company believes that the impact of these standards, when adopted,
will not have a material impact on the Company's consolidated financial
statements.

3.  DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

Cash Equivalents

         The Company estimates that the fair value of cash equivalents
approximates carrying value due to the relatively short maturity of these
instruments.





                                      F-8
<PAGE>   38

Notes Payable

         The Company estimates that the fair value of notes payable
approximates carrying value based upon its effective current borrowing rate for
issuance of debt with similar terms and remaining maturities.

Preferred Stock

         The Company estimates that the fair value of its preferred stocks
approximate carrying value based upon their current dividend rates, terms and
valuation of certain beneficial conversion features.

   Inventories, net of reserves, consist of:

         On April 16, 1996, the Company entered into two term loans and a
revolving loan facility (the "Line of Credit") with CIT which provide for
maximum borrowings of $64.5 million. The Line of Credit provides for financing
based on eligible accounts receivable and inventory, as defined in the
agreement, and expires April 16, 2000 unless otherwise renewed. The term loans
are based on eligible equipment and intangibles. Based on the applicable
calculations, the total available borrowings under the term loans and the Line
of

Credit are approximately $15.9 million as of January 3, 1998. The term loans
and the Line of Credit bear interest at prime plus 1.875 percent (10.375
percent at January 3, 1998). Prior to December 30, 1997 Dennis C. Hayes,
Chairman of the Company, had provided to CIT a $5.0 million guarantee of the
outstanding Line of Credit. The Line of Credit has covenants requiring minimum
levels of tangible net worth and net income, as defined. The Company did not
meet the minimum levels at December 31, 1996, therefore the interest rate was
raised effective January 1, 1997 and the loan amortization on the term
facilities was accelerated effective July 1, 1997.

     The CIT line of credit was replaced on February 20, 1998 by a credit
facility with the Commercial Funding Division of NationsCredit 
("NationsCredit"). The NationsCredit facility consists of two term loans and a 
revolving loan facility which provide for maximum borrowings of $42.5 million.
The revolving loan provides for financing based upon eligible receivables and
inventory. The term loans are based upon appraised values of equipment and
intangibles. The term loans and the revolving loans bear interest at prime plus
0.75% (9.25% at February 20, 1998) and expire four years from inception.

     In April 1996, the Company entered into convertible subordinated promissory
notes (the "Convertible Notes") totaling $6.0 million with certain investors.
The Convertible Notes bore interest at prime plus 1.625 percent and were due on
December 31, 1997. The Convertible Notes were paid in full on January 2, 1998.

     During March 1997, the Company issued additional Convertible Notes totaling
$4.0 million with certain investors. These Convertible Notes bore interest at
prime plus 1.625 percent and were due on December 31, 1997. The Convertible
Notes were paid in full on January 2, 1998.

     The Company's weighted average interest rate on short-term borrowings was
approximately 9.9% and 10.4% at December 31, 1996 and January 3, 1998,
respectively.

     Aggregate maturities of debt, including capitalized lease obligations, for
the next five years are as follows:

     Due to the Hayes Microcomputer's filing of a voluntary petition for
bankruptcy in 1994, subsequent emergence from bankruptcy proceedings in April
1996, and the results of operations for the year ended January 3, 1998, the
Company has recorded a valuation allowance equal to the amount of its net
deferred tax assets. The loss carry forwards as of January 3, 1998 are subject
to annual limitations and will expire from 2010 to 2012.

9.   COMMITMENTS AND CONTINGENCIES

     The Company leases office, plant, and warehouse facilities and certain

     Rental expense was approximately $3.7 million, $1.0 million, $3.9 million
and $3.2 million for the year ended September 30, 1995, the three months ended
December 31, 1995, the years ended December 31, 1996 and January 3, 1998,
respectively.

     There are various litigation proceedings and claims arising in the ordinary
course of business. The Company believes it has meritorious defenses and is
vigorously defending these matters. The Company believes that the resolution of
such contingencies will not have a material adverse effect on the consolidated
financial position, results of operations, or cash flows of the Company.

     The Company has employment agreements with certain management personnel
with terms from six months to five years.

     The Company has an agreement with a supplier of modem chips, under which
the Company committed, under certain circumstances, to purchase a minimum number
of modem chips during 1996. The Company did not purchase the required number of
modem chips and has accrued a potential estimated penalty due the supplier. The
Company and supplier are in negotiations to resolve the matter.

10.  PROFIT SHARING AND 401(K) PLANS

     Prior to October 1, 1994, the Company maintained a separate defined
contribution profit-sharing plan (the "Profit-Sharing Plan") covering
substantially all of the Company's full-time employees.

     On June 22, 1995, the Company authorized an amendment of the Profit Sharing
Plan to allow the Profit-Sharing Plan to be split into separate 401(k) and
profit-sharing components, whereby the profit-sharing component was frozen
retroactive to October 1, 1994 and all balances immediately vested. The 401(k)
component began functioning as a separate plan as of July 1, 1995, and provides
for eligibility for substantially all employees after one month of service and
vesting of matching contributions ratably over a five-year period. The Company
contributed $0.2 million, $0.1 million, $0.3 million and $0.3 million for the
year ended September 30, 1995, the three months ended December 31, 1995, and the
years ended December 31, 1996 and January 3, 1998, respectively.

     Terminated employees are required to sell their stock to the Profit-Sharing
Plan at the appraised value of the stock. Under the terms of the Profit-Sharing
Plan, Hayes Microcomputer had the right to repurchase any shares acquired by the
Profit-Sharing Plan at their appraised value. Hayes Microcomputer repurchased
and retired 76,053 shares for $1.7 million and 652 shares for fourteen thousand
dollars in 1996 and 1997, respectively. There were no shares repurchased in
1995.

     As part of the Plan, the Profit-Sharing Plan was amended to provide for a
one-time election whereby all active participants could convert all or part of
their Hayes Microcomputer stock to cash. In 1996, the Company paid approximately
$0.7 million to the Profit-Sharing plan to repurchase and retire 32,197 shares
of Hayes Microcomputer common stock.

11.  CAPITAL STRUCTURE

(a) Hayes Microcomputer

Common and Preferred Stock

     The Hayes Microcomputer's Restated Articles of Incorporation authorize the
issuance of up to 100,000,000 shares of one cent ($.01) par value common stock.
In accordance with the Plan, Hayes Microcomputer effected a 3.078-to-one reverse
stock split, which reduced the number of outstanding shares by 10,599,595
shares.

     In fiscal 1996, Hayes Microcomputer authorized a new class of no par value
Hayes Microcomputer Series A Preferred Stock consisting of 10,000,000 shares.
The board of directors is authorized to issue the preferred stock in one or more
series and to fix the rights, preferences, privileges, and restrictions of such
stock, including dividend rights, preferences and the number of shares
constituting any series or the designation of such series, without further vote
or action by the shareholders. In connection with the plan Hayes Microcomputer
issued 4,900,000 shares of Hayes Microcomputer Series A Preferred Stock. Such
stock had no dividend rights, but did have preference and priority payment
rights senior to the Hayes Microcomputer Common Stock. The Hayes Microcomputer
Series A Preferred Stock was exchanged for 7,560,576 shares of Hayes Corporation
Common Stock in the Merger.

Stock Redemption Agreements

     In 1988, Hayes Microcomputer entered into an agreement with a stockholder
whereby Hayes Microcomputer could be required to purchase 1,628,884 shares of
common stock at the option of the stockholder at any time after January 1, 1999
through June 2008. In April 1996, in accordance with the Plan, Hayes
Microcomputer repurchased all of the common shares held by a stockholder for
$11.0 million and subsequently retired these shares. In conjunction with this
payment, the shareholder agreement was terminated.





                                      F-13
<PAGE>   43

(b) Hayes Corporation

     The Company's Restated Articles of Incorporation authorize the issuance of
up to 50,000,000 shares of one cent ($.01) par value common stock and up to
10,000,000 shares of preferred stock.

     On February 25, 1998 the Company effected a one for three reverse stock
split. The financial statements have been adjusted to reflect the effect of such
reverse stock split.

12.  REDEEMABLE PREFERRED STOCKS

     During April 1997, the Company completed an agreement with Vulcan to issue
263,113 shares of Hayes Microcomputer Series B Preferred Stock for $5.5 million
which included $45,000 of issuance costs. The preferred stockholders were
entitled to receive cumulative compounding dividends at the rate of 10% per
annum of the original issue price per share of Hayes Microcomputer Series B
Preferred Stock, subject to certain conditions. Hayes Microcomputer Series B
dividends had preference and priority payment over Hayes Microcomputer Series A
Preferred Stock and Hayes Microcomputer Common Stock. These preferred shares had
no voting rights except as required under applicable law or as expressly stated
in the agreement relating to the Hayes Microcomputer Series B Preferred Stock.
Hayes Microcomputer could be required to redeem these preferred shares by a
stated formula at the option of more than 50% of the stockholders at any time
after November 1, 1999. The Series B Preferred Stock also was convertible into
shares of Hayes Microcomputer Common Stock by a stated formula if Hayes
Microcomputer's shares were publicly traded at a stated value per share or in
the aggregate or if the Hayes Microcomputer Series B stockholders obtain an
affirmative majority vote. In the Merger, the Hayes Microcomputer Series B
Preferred Stock was exchanged for Hayes Corporation Series A Preferred Stock
which has terms consistent with those of the Hayes Microcomputer Series B
Preferred Stock.

     On November 12, 1997 Access Beyond and Hayes Microcomputer executed an
agreement to issue $45.0 million of 6% Cumulative Convertible Preferred Stock
("6% Preferred Stock"). Under the preferred stock agreement Access Beyond issued
$10.0 million of the 6% Preferred Stock on the same day and Hayes issued $35.0
million on December 31, 1997.

Conversion Rights

     The 6% Preferred Stock is convertible at any time into shares of Common
Stock at a conversion price (the "Conversion Price") equal to the lesser of (i)
$24.00 per share (the "Fixed Conversion Price") or (ii) 85% of the average
closing bid price of Common Stock for the five consecutive trading days prior to
the date of any conversion notice (the "Market Value"), subject to adjustment
under certain circumstances. If, however, the Company's Common Stock is trading
at a price which would result in a Conversion Price of less than $15.00 per
share then the number of shares of 6% Preferred Stock which may be converted in
any 30 day period is limited to such number of shares of 6% Preferred Stock as
have a liquidation preference of not more than 10% of the amount paid for the 6%
Preferred Stock. If the Conversion Price is below $15.00 per share, then (i) the
first 81.25% of the 6% Preferred Stock for which conversion notices are received
from an investor during a 30 day period will be convertible at a Conversion
Price equal to 85% of the Market Value and the remaining 18.75% will be
convertible at a conversion price equal to 92.5% of the Market Value and (ii)
the Company may redeem the 6% Preferred Stock submitted for conversion for cash
equal to the liquidation preference divided by 85%. In addition, if the
Conversion Price is below $15.00 for more than 5 trading days in any 30 day
period, then for the balance of such 30 day period and for the next 30 day
period, Market Value will be determined on the basis of the lowest 5 consecutive
trading day average closing price during the 15 trading days preceding the
conversion notice.


Redemption

     The Company has the right to redeem the 6% Preferred Stock in whole or in
part, at any time, and from time to time, by paying an amount equal to the
liquidation preference per share divided by 85%. If the Company exercises such
redemption option, then it is required to issue to the investors warrants with a
strike price equal to the higher of $24.00 or the average closing bid price of
the Common Stock during the five trading day period which ends three days before
the redemption date. The number of warrants so issued will be equal to 50% of
the liquidation preference of the shares of 6% Preferred Stock which are
redeemed, divided by such strike price. All shares of 6% Preferred Stock which
have not been converted by the fourth anniversary of the Preferred Stock
agreement are required to then be converted, subject to extension of such date
under certain circumstances.





                                      F-14
<PAGE>   44

     Under certain circumstances, including the failure of the Company to
maintain a listing on an approved market for its common stock, suspension of
trading in its common stock for specified periods, a change of control (as
defined in the preferred stock agreements), holders of the 6% Preferred Stock
may require the Company to repurchase the 6% Preferred Stock, as defined in the
agreement.

Dividends

     The shares of 6% Preferred Stock are entitled to receive cumulative
dividends at the rate of 6% per annum, payable in cash, or in Common Stock, or
by adding the amount of any dividend to the liquidation preference. No
distribution, whether by way of dividend or otherwise, may be declared or paid
upon or set apart for any class of security of the Company which is junior to
the 6% Preferred Stock if, at such time, any dividends on the 6% Preferred Stock
have not been paid or declared and set apart for payment with respect to all
preceding periods.

     The terms of the preferred stock agreement which permit the conversion of
the 6% Preferred Stock at a discount to market is considered a beneficial
conversion feature (the "Beneficial Conversion Feature"). The Beneficial
Conversion Feature at the date of issuance of the security was recognized as a
dividend to the holders of the security. Based upon the terms of the preferred
stock agreement and the market value of the Company's Common Stock, on the date
of issue, the Company valued the undiscounted Beneficial Conversion Feature of
the 6% Preferred Stock at $3.5 million and recorded a dividend of the same
amount on December 31, 1997. The beneficial dividend does not effect the number
of 6% Preferred Stock shares outstanding or the number of common shares issuable
upon conversions of the 6% Preferred Stock or require any additional payments or
compensation to the holders of the 6% Preferred Stock.

13. STOCK-BASED COMPENSATION

(a) Warrants

     In connection with the Plan, Hayes Microcomputer authorized 600,000
warrants to purchase shares at their estimated fair value on the date of grant.
Hayes Microcomputer issued 400,000 warrants during April 1996 at an exercise
price of $0.714 per share. The warrants were exchanged for 617,190 warrants of
Hayes Corporation and became exercisable and fully vested on the date of the
Merger. The warrants expire five years from the date of the Merger. The warrants
were issued to Directors and are valued and presented as options in the
information below.

(b) Hayes Microcomputer

     The Hayes Microcomputer Products, Inc. Stock Option Plan (the "Hayes
Microcomputer Plan") was adopted by the Hayes Microcomputer stockholders in June
1996. No options were granted prior to that date. Options granted under the
Hayes Microcomputer Plan may be either (i) options intended to qualify as
incentive stock options ("ISO's") under Section 422 of the Internal Revenue Code
or (ii) non-qualified stock options. None of the options granted in 1996 were
intended to qualify as ISO's. The Stock Option Plan allows for three types of
grants: Executive, Management, and Performance Grants. Pursuant to the terms of
the Merger, the Hayes Microcomputer Plan was frozen and no further options may
be granted. In addition, each Hayes Microcomputer option outstanding at the
Merger was exchanged for 1.54297 options for Hayes Corporation Common Stock.

     An explanation of each type of grant and a description of the options
awarded under each type of grant are as follows:

Executive Grant

     Hayes Microcomputer granted options to purchase shares at exercise prices
ranging from $0.462 to $0.648 per share. The options were subject to a vesting
schedule and became exercisable at the Merger. The options expire five years
after the date of the Merger.

Management Grant

         Hayes Microcomputer granted options to purchase shares at exercise
prices ranging from $0.462 to $13.61 per share. The options expire ten years
after the date of grant and become exercisable and vest based on a five-year
ratable vesting schedule beginning at the date of grant.





                                      F-15
<PAGE>   45

Performance Grant

     Hayes Microcomputer granted options to purchase shares at exercise prices
ranging from $0.648 to $0.817 per share. Vesting will be determined based on the
attainment of specified average share prices as defined in the Stock Option
Plan. The average share prices range from $15.68 to $39.19. To the extent share
price objectives are not attained, the option shares vest on the ninth
anniversary of the grant.

(c)  Access Beyond

Incentive Plan

     The board of directors unanimously adopted and approved the 1996 Incentive
Long-Term Option Plan on November 18, 1996, and unanimously adopted the plan as
amended and restated, on February 4, 1997 (the "Incentive Plan"). The Incentive
Plan was approved by stockholders at a Special Meeting on March 6, 1997. On
December 5, 1996, the Company granted 360,000 options to officers and key
employees of the Company at an exercise price of $19.875, on February 4, 1997,
an additional 25,000 options were granted at an exercise price of $20.25 and on
June 4, 1997, an additional 104,667 options were granted at an exercise price of
$12.00. All of such options vest at the rate of 30% after one (1) year, 60%
after two (2) years and 100% after three (3) years, subject to acceleration in
certain circumstances.

Directors' Plan

     The board of directors unanimously adopted and approved the 1996
Non-employee Directors' Stock Option Plan on November 18, 1996, and unanimously
adopted the plan, as amended and restated, on February 4, 1997 (the "Directors'
Plan"). The Directors' Plan was approved by stockholders at a Special Meeting on
March 6, 1997. In accordance with the provisions of the Directors' Plan each
non-employee director, or his or her designee (s), was granted 8,333 options
("Options") under the Directors' Plans on November 18, 1996, at the exercise
price of $23.2125. Pursuant to the terms of the Directors' Plan, each director
is entitled to a grant of 1,667 shares on the fifth business day following the
Company's filing of an annual report on Form 10-K. Each non-employee director
received a grant of 1,667 shares at an exercise price of $16.875 on October 21,
1997. On December 30 and 31, 1997 the new non-employee directors elected to the
board of directors were granted 8,333 options at exercise prices of $12.54 and
$12.75. All of such Options vest at the rate of 30% after one (1) year, 60%
after two (2) years and 100% after three (3) years, subject to acceleration in
certain circumstances, including the occurrence of a transaction such as the
Merger.

     As a result of the Merger the options granted on November 18, 1996 and
October 21, 1997 immediately vested and must be exercised by March 30, 1998 or
such option expires.

     Options historically have been granted based on an amount greater than or
equal to the fair value of the shares at the date of grant. If no quoted market
price was available, the best estimate of the fair value of the stock was
determined by the board of directors.

     The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following assumptions used for
grants in 1997: dividend yield of 0%, expected volatility of 72.2%, risk- free
interest rate of 5.57%, and an expected term of 4.9 years.

     The Company applies APB Opinion 25 and related interpretations in
accounting for its plans. For the fiscal year ended January 3, 1998, $0.2
million of compensation expense was recognized for its stock option plans. Had
compensation expense for the Company's stock-based compensation plans been
determined under the provisions consistent with Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation," the
Company's net loss for the year ended January 3, 1998, would have been the pro

     Operating profit (loss) is calculated as total revenue less total operating
expenses. In calculating operating profit, none of the following items have been
added or deducted: net interest expense, net miscellaneous income,
reorganization items, or income taxes. Identifiable assets are those assets of
the Company that are identified with the operations in each geographic area,
including goodwill.

     The Company generates significant sales outside the United States and is
subject to risks generally associated with international operations. The foreign
operations of the Company accounted for approximately 15%, 22%, 25% and 38% of
the Company's net sales for the year ended September 30,1995, the three months
ended December 31, 1995, the years ended December 31, 1996 and January 3, 1998,
respectively. Accordingly, the Company's financial results from international
operations may be affected by the economic, political, and regulatory climates
prevailing in the respective foreign countries and by fluctuations in currency
exchange rates.

15.  ACQUISITIONS

(a)  Cardinal Technologies, Inc.

     During April 1997, the Company acquired 100% of the outstanding common
stock of Cardinal, a private manufacturer of modems and ISDN adapters, for $2.5
million. The acquisition has been accounted for utilizing the purchase method of
accounting. The estimated fair values assigned to the assets and liabilities
acquired were as follows:

</TABLE>

     Pro forma results of operations of Cardinal from the beginning of the
period through the acquisition date are not presented as they are not
significant to the Company's consolidated results of operations.

(b)  Access Beyond, Inc.

     On December 30, 1997, Access Beyond completed the Merger with Hayes
Microcomputer. In the Merger, Access Beyond issued 15,261,763 shares of Common
Stock and 405,977 shares of Series A Preferred Stock, after giving effect to a
one for three reverse stock split effected February 25, 1998. The stock issued
in the transaction represented 79% of the outstanding stock immediately after
the Merger excluding the effect of warrants, stock options, and the 6%
Cumulative Convertible Preferred Stock. Immediately following the Merger, the
Company changed its name to Hayes Corporation. Since the Hayes Microcomputer
shareholders received a substantial majority of the shares of stock of the
Company, the transaction is treated as a reverse acquisition of the Company by
Hayes Microcomputer for accounting purposes. As a result, the historical
financial statements of the surviving company for the periods prior to the
Merger are those of Hayes Microcomputer rather than those of Access Beyond.

</TABLE>

     Approximately $55.0 million of the total purchase price represented the
value of in-process research and development based on an appraisal of the
product line that had not yet reached technological feasibility and had no
alternative future use. The amount was determined using the income forecast
method and was charged to the Company's operations in the fourth quarter.

     The following pro forma results of operations have been prepared as though
the Merger had occurred as of the beginning of the periods presented. The pro
forma information does not purport to be indicative of the results of operations
that would have been attained had the merger been in effect on the dates
indicated, nor of future results of operations of the Company.

16. SIGNIFICANT RISKS AND UNCERTAINTIES

     The communications industry is highly competitive and competition is
expected to intensify. There are numerous companies competing in various
segments of the market in which the Company does business. Competitors include
organizations significantly larger and with more development, marketing and
financial resources than the Company. The Company's success is dependent on its
ability to develop and market products that are innovative, cost-competitive and
meet customer expectations.

     The markets for the Company's products are characterized by rapid
technological developments resulting in short product life cycles. The market
for modems is primarily dependent upon the market for personal computers. From
diminished product demand, production over capacity, and resultant accelerated
erosion of average selling prices, the Company's business could be materially
and adversely affected by industry-wide fluctuations in the personal computer
marketplace in the future. The Company's ten largest customers account for
approximately 57%, 56%, 73% and 55% of net sales for the year ended September
30, 1995, the three months ended December 31, 1995, the years ended December 31,
1996 and January 3, 1998, respectively. The Company has one customer which
accounts for 14% of net sales at January 3, 1998.

     The Company's accounts receivable are concentrated with a limited number of
customers. The amounts owed by the largest ten customers represented
approximately 55% and 52 % of the total accounts receivable balances as of
December 31, 1996 and January 3, 1998, respectively. The Company has one
customer which accounts for 17% of accounts receivable as of January 3, 1998.

17.  RELATED PARTY TRANSACTIONS

     As of January 3, 1998, the Company has the following related party
transactions:

     The Company has a split-dollar life insurance policy on a shareholder of
the Company with the Company as the beneficiary. The split-dollar agreement is
included in other long-term assets in the amount of $0.6 million and $0.9
million as of December 31,1996 and January 3, 1998, respectively. The cash
surrender value, included in prepaids and other current assets, is $0.3 million
as of December 31, 1996 and January 3, 1998.





                                      F-19
<PAGE>   49

     A shareholder of the Company had a revolving credit arrangement with the
Company stating a maximum draw of $0.3 million. The balance outstanding,
included in prepaids and other current assets, is $0.2 million as of December
31,1996. The arrangement was paid in full and terminated in December 1997.

     The Company has manufacturing subcontractor agreements with two of its
stockholders. During 1996 and 1997 the Company purchased $44.8 million and $47.4
million respectively, of finished goods from such manufacturers.

     On December 10, 1997, Hayes sold 72,277 shares of common stock of BVRP
Software S.A. ("BVRP"), to an affiliate of ACMA Limited, a shareholder of Hayes,
for a purchase price of approximately $2.0 million. Such shares were sold at a
discount of 15% from the market price established by the average of the closing
price of BVRP for the three days prior to November 25, 1997. BVRP common stock
is registered and traded on the Nouveau Marche.

     The Company believes that these transactions were all negotiated at arms
length.

18.  NET LOSS PER COMMON SHARE

     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings Per Share" ("FAS 128"). This statement establishes standards
for computing and presenting earnings per share ("EPS"). Basic EPS excludes
dilution and is computed by dividing income available to common stockholders by
the weighted-average number of common shares outstanding for the period. Diluted
EPS reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock or
resulted in the issuance of common stock that then shared in the earnings of the
entity. FAS 128 requires restatement of all prior-period EPS data presented.

     Potential common stock equivalents such as stock options and warrants have
an anti-dillutive effect on the year ended September 30, 1995, the three months
ended December 31, 1995 and the years ended December 31, 1996 and January 3,
1998 diluted net loss per common share calculations.

                  (ORIGINALLY INCORPORATED ON JULY 23, 1996)

      The address of the registered office of the Corporation in the State of
Delaware is 1209 Orange Street, Wilmington, New Castle County, Delaware. The
name of its registered agent at that address is The Corporation Trust Company.


                                  ARTICLE III

      The purpose of the Corporation is to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of the
State of Delaware.


                                  ARTICLE IV

      The total number of shares of all classes of stock which the Corporation
has authority to issue is one hundred million (100,000,000) shares, consisting
of two classes: __________________ (__________) shares of Common Stock, $.01 par
value per share, and __________________ (__________) shares of Preferred Stock,

are designated as Series A Preferred Stock.

      The Board of Directors is authorized, subject to any limitations
prescribed by the law of the State of Delaware, to provide for the issuance of
the shares of Preferred Stock in one or more series, and, by filing a
certificate of designation pursuant to the applicable law of the State of
Delaware, to establish from time to time the number of shares to be included in
each such series, to fix the designation, powers, preferences and rights of the
shares of each such wholly unissued series and any qualifications, limitations
or restrictions thereof, and to increase or decrease the number of shares of any

entitled to vote, unless a vote of any other holders is required pursuant to a
certificate or certificates establishing a series of Preferred Stock.

      Except as otherwise expressly provided in Article V or in any Certificate
of Designation designating any series of Preferred Stock pursuant to the
foregoing provisions of this Article IV, any new series of Preferred Stock may
be designated, fixed and determined as provided herein by the Board of Directors
without approval of the holders of the Common Stock or the holders of Preferred
Stock, or any series thereof, and any such new series may have powers,
preferences and rights, including, without limitation, voting rights, dividend
rights, liquidation rights, redemption rights and conversion rights, senior to,
junior to or pari passu with the rights of the Common Stock, the Preferred
Stock, or any future class or series of Preferred Stock or Common Stock.


                                   ARTICLE V

      The rights, preferences, privileges and restrictions granted to and
imposed on the Series A Preferred Stock and the Common Stock are as follows:

      1.    DIVIDEND RIGHTS. The holders of Series A Preferred Stock shall be
      entitled to receive, as and when declared by the Board, but only out of
      funds legally available therefor, cumulative compounding dividends at the
      dividend rate of ten percent (10%) per annum of $______. [THIS BLANK WILL
      EQUAL THE ORIGINAL ISSUE PRICE PER SHARE OF HAYES SERIES B PREFERRED STOCK
      ($20.9036) DIVIDED BY THE CONVERSION RATIO] Dividends shall accrue
      quarterly as if such dividends had commenced to accrue on April 24, 1997,
      provided, however, that in the event of conversion of the Series A
      Preferred Stock (as set forth in Section 3), dividends shall be accrued
      through the day immediately prior to such conversion. Subject to the
      restrictions set forth in this Section 1, dividends accumulated on the
      Series A Preferred Stock shall be declared by the Board and paid on the
      Redemption Date provided that the Redemption Request is provided as set
      forth in Section 7. Such dividends shall be paid in cash upon redemption,
      or in additional shares of Common Stock upon conversion of the Series A
      Preferred Stock as provided in Section 3 below. Dividends accumulated on
      the Series A Preferred Stock shall be declared by the Board and paid in
      cash every three (3) months to the extent permitted by law. No dividends
      may be paid on the Common Stock unless all accrued and unpaid dividends on
      the Series A Preferred Stock are paid.

      2.    VOTING RIGHTS.

            (a) Common Stock. Each holder of shares of Common Stock shall be
      entitled to one (1) vote for each share thereof held.

            (b) Preferred Stock. Each holder of shares of Series A Preferred
      Stock shall be entitled to the number of votes equal to the number of
      whole shares of Common Stock into which such shares of Series A Preferred
      Stock could be converted pursuant to the
                      
                                        2
<PAGE>   3
      provisions of Section 3 below at the record date for the determination of
      the shareholders entitled to vote on such matters or, if no such record
      date is established, the date such vote is taken or any written consent of
      shareholders is solicited.

            (c) Vote Required. Subject to the foregoing provisions of this
      Section 2, each holder of Preferred Stock shall have full voting rights
      and powers equal to the voting rights and powers of the holders of Common
      Stock, and shall be entitled to notice of any shareholders' meeting in
      accordance with the bylaws of the Company (as in effect at the time in
      question) and applicable law, and shall be entitled to vote, together with
      the holders of Common Stock, with respect to any question upon which
      holders of Common Stock have the right to vote, except as may be otherwise
      provided by applicable law. Except as otherwise required by law or by the
      provisions of Section 5 of this Article V, the holders of Preferred Stock
      and the holders of Common Stock shall vote together and not as separate
      classes.

      3. CONVERSION RIGHTS. The holders of Series A Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

            (a) Right to Convert. Each share of Series A Preferred Stock shall
      be convertible, at the option of the holder thereof, at any time after the
      date of issuance of such share at the office of the Corporation or any
      transfer agent for such stock, into such number of fully paid and
      nonassessable shares of Common Stock as is determined by dividing US
      $______ [THIS BLANK WILL EQUAL $20.9036 DIVIDED BY THE CONVERSION RATIO]
      by the Series A Conversion Price determined as hereinafter provided, in
      effect on the date the certificate is surrendered for conversion. If any
      holder elects to convert his shares of Series A Preferred Stock as
      provided above, all unpaid and accrued dividends on the Series A Preferred
      Stock existing immediately prior to the conversion of the Series A
      Preferred Stock will be converted into such number of fully paid and
      nonassessable shares of Common Stock as determined by dividing all unpaid
      and accrued dividends by the Series A Conversion Price, determined as
      hereinafter provided. The "Series A Conversion Price" shall initially be
      US $__________ [THIS BLANK WILL EQUAL $20.9036 DIVIDED BY THE CONVERSION
      RATIO]. Such initial Series A Conversion Price shall be adjusted as
      hereinafter provided.

            (b) Automatic Conversion. Each share of Series A Preferred Stock
      shall automatically be converted (as set forth below) into such number of
      fully paid and nonassessable shares of Common Stock as determined by
      dividing US $_____ [THIS BLANK WILL EQUAL $20.9036 DIVIDED BY THE
      CONVERSION RATIO] (adjusted for any stock splits, stock dividends, stock
      combinations or similar events) plus the per share amount of all unpaid
      and accrued dividends on the Series A Preferred Stock existing immediately
      prior to the conversion of the Series A Preferred Stock by the Series A
      Conversion Price, determined as hereinafter provided, in effect (i)
      immediately prior to the consummation of a Qualified Public Offering (as
      defined below) under the Securities Act of 1933, as amended (the
      "Securities Act"); or (ii) at such time as the Corporation has registered
      Common Stock pursuant to an underwritten public offering under the
      Securities Act and
                                   
                                        3
<PAGE>   4
      (a) the Corporation has listed or would be qualified to list its shares on
      the NASDAQ National Market System; (b) the average market value of the
      Common Stock equals or exceeds the lesser of US $_________ [THIS BLANK
      WILL EQUAL $33.00 DIVIDED BY THE CONVERSION RATIO] per share or two (2)
      times the then-current Series A Conversion Price (in either such case as
      adjusted for stock splits, stock dividends, stock combinations or similar
      events) determined by the median of the high and low sales price each day
      for a consecutive twenty (20) day period; (c) the aggregate market value
      of the shares of Common Stock held in the public market equals or exceeds
      US $25,000,000, determined by the 20 trading day average of the high and
      low sales price described in (b) above; and (d) the holders of the Series
      A Preferred Stock have the unrestricted right at such time to sell in a
      registered offering or pursuant to Rule 144 at least one-half of the
      number of shares of Common Stock into which such Series A Preferred Stock
      would be converted; or (iii) upon the affirmative vote of holders of at
      least a majority of the Series A Preferred Stock (any such event described
      in subsections (i), (ii) and (iii) above being referred to herein as a
      "Series A Conversion Event"). All unpaid and accrued dividends on the
      Series A Preferred Stock existing immediately prior to the Series A
      Conversion Event shall automatically be converted into such number of
      fully paid and nonassessable shares of Common Stock as determined by
      dividing all unpaid and accrued dividends by the Series A Conversion
      Price, determined as hereinafter provided, in effect immediately prior to
      the Series A Conversion Event. As used herein, "Qualified Public Offering"
      means an underwritten sale to the public of Common Stock pursuant to an
      effective registration statement under the Securities Act in connection
      with which (a) the gross proceeds to the Corporation for the Common Stock
      actually sold to the public in such sale, prior to deducting the amount of
      brokers' commissions and expense allowances paid by the Corporation in
      connection with the original sale of such Common Stock, is US $25,000,000
      or more, and (b) the public offering price per share (prior to
      underwriters' commissions and expenses) equals or exceeds the lesser of
      (i) US $______ [THIS BLANK WILL EQUAL $33.00 DIVIDED BY THE CONVERSION
      RATIO] per share or (ii) two (2) times the then-current Series A
      Conversion Price, in either such case as adjusted for stock splits, stock
      dividends, stock combinations or similar events. Immediately prior to the
      Qualified Public Offering, or promptly upon the occurrence of another
      Series A Conversion Event, each share of Series A Preferred Stock shall be
      automatically converted, without cost, on the terms of this Section 3(b),
      into the number of shares of Common Stock into which such share of Series
      A Preferred Stock would be convertible under Section 3 immediately prior
      to such Series A Conversion Event.

            (c)   Mechanics of Conversion.

                  (i)   Before any holder of Series A Preferred Stock shall be
                        entitled to convert the same into shares of Common
                        Stock, such holder shall surrender the certificate or
                        certificates therefor, duly endorsed, at the office of
                        the Corporation or of any transfer agent for such stock,
                        and shall give written notice to the Corporation at such
                        office that such holder elects to convert the same and
                        shall state therein the name or names in which such
                        holder wishes the

                                      4
<PAGE>   5
                        certificate or certificates for shares of Common Stock
                        to be issued. The Corporation shall, as soon as
                        practicable thereafter, issue and deliver at such office
                        to such holder of Series A Preferred Stock, a
                        certificate or certificates for the number of shares of
                        Common Stock to which such holder shall be entitled as
                        aforesaid. Such conversion shall be deemed to have been
                        made immediately prior to the close of business on the
                        date of surrender of the shares of Series A Preferred
                        Stock to be converted, 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.

                  (ii)  If a conversion is in connection with an underwritten
                        offering of securities pursuant to the Securities Act,
                        the conversion may, at the option of any holder
                        tendering shares of Series A Preferred Stock for
                        conversion, be conditioned upon the closing with the
                        underwriters of the sale of securities pursuant to such
                        offering, in which event the person(s) entitled to
                        receive the Common Stock upon conversion of the Series A
                        Preferred Stock shall not be deemed to have converted
                        such Series A Preferred Stock until immediately prior to
                        the closing of such sale of securities.

            (d)   Adjustments to Conversion Price for Certain Diluting Issues.

                  (i)   Special Definitions.  For purposes of this Section 3(d),
                        the following definitions apply:

                        (A)   "Options" shall mean rights, options or warrants

                              convertible into or exchangeable for Common Stock.

                        conversion or exchange of such Convertible Securities,
                        shall be deemed to be Additional Shares of Common Stock
                        issued as of the time of such issue or, provided that in
                        any such case in which Additional Shares of Common Stock
                        are deemed to be issued:

                        (A)   no further adjustments in the Series A Conversion

                              otherwise, for any increase or decrease in the

                              thereof, and any subsequent adjustments based
                              thereon, shall, upon any such increase or decrease
                              becoming effective, be recomputed to reflect such
                              increase or decrease insofar as it affects such
                              Options or the rights of conversion or exchange
                              under such Convertible Securities (provided,
                              however, that no such adjustment of the Series A
                              Conversion Price shall affect the Common Stock
                              previously issued upon conversion of the Series A
                              Preferred Stock);

                                    pursuant to Section 3(d)(v)) upon the issue
                                    of the Convertible Securities with respect
                                    to which such Options were actually

                              Price on the original adjustment date, or (2) the
                              Series A Conversion Price that would have resulted
                              from any issuance of Additional Shares of Common
                              Stock between the original adjustment date and

                              expiration or exercise of all such Options,
                              whereupon such adjustment shall be made in the
                              same manner provided in clause (C) above.

                  (iv)  Adjustment of Series A Conversion Price Upon Issuance of
                        Additional Shares of Common Stock. In the event this
                        corporation, at any time after the Original Issue Date

                        $20.9036 DIVIDED BY THE CONVERSION RATIO] per share but
                        equal to or greater than US $______ [THIS BLANK WILL
                        EQUAL $7.14 DIVIDED BY THE CONVERSION RATIO] per share
                        (in each case as adjusted for any stock splits, stock
                        dividends, stock combinations or similar events) then
                        and in such event, the Series A Conversion Price shall
                        be reduced concurrently with such issue, to a price
                        equal to the lowest per share consideration received by
                        the Corporation for any of the Additional Shares of
                        Common Stock. If such price per share of Additional
                        Shares is less than US $________ [THIS BLANK WILL EQUAL
                        $7.14 DIVIDED BY THE CONVERSION RATIO] (adjusted for any
                        stock splits, stock dividends, stock combinations or
                        similar events) then and in such event, the Series A

                        RATIO] and then the Series A Conversion Price shall be
                        further reduced, concurrently with such issue, to a
                        price (calculated to the nearest cent) determined by
                        multiplying such Series A Conversion Price by a
                        fraction, (i) the numerator of which shall be the number
                        of shares of Common Stock issuable upon conversion of
                        the shares of the Series A Preferred Stock actually
                        issued and outstanding (or deemed issued pursuant to
                        Section 3(d)(iii)) immediately prior to such issue plus
                        the quotient obtained by dividing (x) the aggregate
                        consideration received by the Corporation for the total
                        number of Additional Shares of Common Stock so issued
                        (or deemed issued pursuant to Section 3(d)(iii)) by (y)
                        the Series A Conversion Price in effect immediately
                        prior to such issuance, and (ii) the denominator of
                        which shall be the number of shares of Common Stock
                        issuable upon conversion of the shares of the Series A
                        Preferred Stock actually issued and outstanding (or
                        deemed issued pursuant to Section 3(d)(iii)) immediately
                        prior to such issue plus the number of such Additional
                        Shares of Common Stock so issued (or deemed issued
                        pursuant to Section 3(d)(iii)).

                  (v)   Determination of Consideration. For purposes of this
                        Section 3(d), the consideration received by the
                        Corporation for the issue of any Additional Shares of
                        Common Stock shall be computed as follows:

                        (A)   Cash and Property.  Such consideration shall:

                              (1)   insofar as it consists of cash, be computed
                                    at the aggregate amount of cash received by
                                    the Corporation (without deducting any
                                    discounts or commissions paid by the
                                    Corporation);

                              (2)   insofar as it consists of property other
                                    than cash, be computed at the fair value
                                    thereof at the time of such issue, as
                                    determined in good faith by the Board; and

                              (3)   in the event Additional Shares of Common
                                    Stock are issued together with other shares
                                    or securities or other assets of the
                                    Corporation for consideration which covers
                                    both, be the proportion of such
                                    consideration so received, computed as
                                    provided in clauses (1) and (2) above, as
                                    determined in good faith by the Board.

                        (B)   Options and Convertible Securities. The
                              consideration per share received by the
                              Corporation for Additional Shares of Common Stock
                              deemed to have been issued pursuant to Section
                              3(d)(iii), relating to Options and Convertible
                              Securities shall be determined by dividing:

                              (1)   the maximum amount, if any, received or
                                    receivable by the Corporation as
                                    consideration for the issue of such Options
                                    or Convertible Securities, plus the minimum
                                    aggregate amount of additional consideration
                                    (as set forth in the instruments relating
                                    thereto, without regard to any provision
                                    contained therein designed to protect
                                    against dilution) payable to the Corporation
                                    upon the exercise of such Options or the
                                    conversion or exchange of such Convertible
                                    Securities, or in the case of Options for
                                    Convertible Securities, the exercise of such
                                    Options for Convertible Securities and the
                                    conversion or exchange of such Convertible
                                    Securities, by

                              (2)   the maximum number of shares of Common Stock
                                    (as set forth in the instruments relating
                                    thereto, without regard to any provision
                                    contained therein designed to protect
                                    against dilution) issuable upon the exercise
                                    of such Options or conversion or exchange of
                                    such Convertible Securities.

            (e) Adjustments for Stock Dividends, Subdivisions, or Split-ups of
Common Stock. If the number of shares of Common Stock outstanding at any time
after the filing of this Restated Certificate of Incorporation is increased by a
stock dividend payable in shares of Common Stock or by a subdivision or split-up
of shares of Common Stock, then, effective at


                                      10
<PAGE>   11
the close of business upon the record date fixed for the determination of
holders of Common Stock entitled to receive such stock dividend, subdivision or
split-up, the Series A Conversion Price shall be appropriately decreased so that
the number of shares of Common Stock issuable on conversion of each share of
Series A Preferred Stock shall be increased in proportion to such increase of
outstanding shares of Common Stock.

            (f) Adjustments for Combinations of Common Stock. If the number of
shares of Common Stock outstanding at any time after the filing of this Restated
Certificate of Incorporation is decreased by a combination of the outstanding
shares of Common Stock, then, effective at the close of business upon the record
date of such combination, the Series A Conversion Price shall be appropriately
increased so that the number of shares of Common Stock issuable on conversion of
each share of Series A Preferred Stock shall be decreased in proportion to such
decrease in outstanding shares of Common Stock.

            (g) Adjustments for Other Distributions. In the event the
Corporation at any time or from time to time makes, or fixes a record date for
the determination of holders of Common Stock entitled to receive any
distribution payable in securities of the Corporation other than shares of
Common Stock, then and in each such event provision shall be made so that the
holders of Series A Preferred Stock shall receive upon conversion thereof, in
addition to the number of shares of Common Stock receivable thereupon, the
amount of securities of the Corporation which they would have received had their
Series A Preferred Stock been converted into Common Stock on the date of such
event and had they thereafter, during the period from the date of such event to
and including the date of conversion, retained such securities receivable by
them as aforesaid during such period, subject to all other adjustments called
for during such period under this Section 3(g) with respect to the rights of the
holders of the Series A Preferred Stock.

            (h) Adjustments for Reorganizations, Reclassifications, etc. If the
Common Stock issuable upon conversion of the Series A Preferred Stock shall be
changed into the same or a different number of shares of any other class or
classes of stock or other securities or property, whether by reclassification, a
merger or consolidation of this corporation with or into any other corporation
or corporations, or a sale of all or substantially all of the assets of this
corporation (but only if the stockholders of this corporation hold more than
fifty percent (50%) of the outstanding voting equity securities of the surviving
corporation in such merger, consolidation or sale of assets reorganization), or
otherwise (other than a subdivision or combination of shares provided for above
or a merger or other transaction referred to in Section 4(c) below) the Series A
Conversion Price then in effect shall, concurrently with the effectiveness of
such reorganization or reclassification, be proportionately adjusted such that
the Series A Preferred Stock shall be convertible into, in lieu of the number of
shares of Common Stock which the holders would otherwise have been entitled to
receive, a number of shares of such other class or classes of stock or
securities or other property equivalent to the number of shares of Common Stock
that would have been subject to receipt by the holders upon conversion of the
Series A Preferred Stock immediately before such event; and, in any such case,
appropriate adjustment (as determined by the Board) shall be made in the
application of the provisions herein set forth with respect to the rights and
interests thereafter of the holders of the


            
                                       11
<PAGE>   12
Series A Preferred Stock, to the end that the provisions set forth herein
(including provisions with respect to changes in and other adjustments of the
Series A Conversion Price) shall thereafter be applicable, as nearly as may be
reasonable, in relation to any shares of stock or other property thereafter
deliverable upon the conversion of the Series A Preferred Stock. In the event of
any conflict between this Section 3(h) and Section 4(b), Section 4(b) shall be
controlling.

            (i) No Impairment. The corporation will not, except by a properly
approved amendment of its Certificate of Incorporation, through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Corporation, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 3 and in the taking of all
such action as may be necessary or appropriate in order to protect the
Conversion Rights of the holders of the Series A Preferred Stock against
impairment.

            (j) Certificates as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Series A Conversion Price pursuant to this
Section 3, the Corporation at its expense shall promptly compute such adjustment
or readjustment in accordance with the terms hereof and prepare and furnish to
each holder of Series A Preferred Stock, a certificate executed by the
Corporation's President/Chief Executive Officer or Treasurer/Chief Financial
Officer setting forth such adjustment or readjustment and showing in detail the
facts upon which such adjustment or readjustment is based. The corporation
shall, upon the written request at any time of any holder of Series A Preferred
Stock, furnish or cause to be furnished to such holder a like certificate
setting forth (A) such adjustments and readjustments, (B) the Conversion Price
at the time in effect, and (C) the number of shares of Common Stock and the
amount, if any, of other property which at the time would be received upon the
conversion of the Series A Preferred Stock.

            (k) Notices of Record Date. In the event that the Corporation shall
propose at any time: (a) to declare any special dividend or distribution upon
its Common Stock, whether in cash, property, stock or other securities, whether
or not out of earnings or earned surplus; (b) to offer to subscription pro rata
to the holders of any class or series of its stock any additional shares of
stock of any class or series or other rights; (c) to effect any reclassification
or recapitalization of its Common Stock outstanding involving a change in the
Common Stock; or (d) to merge or consolidate with or into any other corporation
(other than a mere reincorporation transaction), or sell, lease or convey all or
substantially all of its assets, or to liquidate, dissolve or wind up; then, in
connection with each such event, the Corporation shall send to the holders of
Series A Preferred Stock:

                  (A)   at least twenty (20) days' prior written notice of the
                        date on which a record shall be taken for such dividend,
                        distribution or subscription rights (and specifying the
                        date on which the holders of Common Stock shall be
                        entitled thereto) or for determining



                                      12
<PAGE>   13
                        rights to vote, if any, in respect of the matters
                        referred to in (c) and (d) above; and

                  (B)   in the case of the matters referred to in (c) and (d)
                        above, at least twenty (20) days' prior written notice
                        of the date when the same shall take place (and
                        specifying the date on which the holders of Common Stock
                        shall be entitled to exchange their Common Stock for
                        securities or other property deliverable upon the
                        occurrence of such event).

            (l) Issue Taxes. The corporation shall pay any and all issue and
other taxes that may be payable in respect of any issue or delivery of shares of
Common Stock on conversion of Series A Preferred Stock pursuant hereto;
provided, however, that the Corporation shall not be obligated to pay any
transfer taxes resulting from any transfer requested by any holder in connection
with any such conversion.

            (m) 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 A Preferred Stock, such number of its shares of Common
Stock as shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series A 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 A
Preferred Stock, the Corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purpose, including, without limitation, engaging in its best efforts to obtain
the requisite stockholder approval of any necessary amendment to the Certificate
of Incorporation.

            (n) Fractional Shares. No fractional share shall be issued upon the
conversion of any share or shares of Series A Preferred Stock. All shares of
Common Stock (including fractions thereof) issuable upon conversion of more than
one share of Series A Preferred Stock by a holder thereof shall be aggregated
for purposes of determining whether the conversion would result in the issuance
of any fractional share. If, after the aforementioned aggregation, the
conversion would result in the issuance of a fraction of a share of Common
Stock, the Corporation shall, in lieu of issuing any fractional share, pay the
holder otherwise entitled to such fraction a sum in cash equal to the fair
market value of such fraction on the date of conversion (as determined in good
faith by the Board).

            (o) Notices. Any notice required by the provisions of this Section 3
to be given to the holders of shares of Series A Preferred Stock shall be given
in writing and it or any certificates or other documents delivered hereunder
shall be deemed effectively given or delivered (as the case may be) upon
personal delivery; when deposited with a recognized international courier, five
(5) days after deposit (or if earlier, upon delivery against a signed receipt
therefor); when transmitted by telecopy, which transmission is confirmed, at the
address appearing on the books of the Corporation.

      4.    LIQUIDATION RIGHTS.

            (a) In the event of any liquidation, dissolution or winding up of
the Corporation, whether voluntary or involuntary, the holder of each share of
the Series A Preferred Stock then outstanding shall be entitled to receive out
of the remaining assets of the Corporation available for distribution to
stockholders, and before any payment or declaration and setting apart for
payment of any amount shall be made in respect of Common Stock, an amount equal
to $________. [THIS BLANK WILL EQUAL THE ORIGINAL ISSUE PRICE PER SHARE OF HAYES
SERIES B PREFERRED STOCK ($20.9036) DIVIDED BY THE CONVERSION RATIO] (which
amount shall be adjusted proportionately in the event the shares of Series A
Preferred Stock are subdivided into a greater number or combined into a lesser
number) plus an amount equal to any accrued but unpaid dividends through the
date of such liquidation, dissolution or winding up of the Corporation (the
"Series A Preferred Stock Liquidation Preference"). If, upon any liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the assets to be distributed to the holders of Series A Preferred Stock shall be
insufficient to permit the payment of the full Series A Preferred Stock
Liquidation Preference pursuant to this Section 4(a), then all of the remaining
assets of the Corporation to be distributed shall be distributed ratably to the
holders of Series A Preferred Stock.

            (b) A merger, consolidation or reorganization of the Corporation
with or into any other corporation or corporations that results in the transfer
of fifty percent (50%) or more of the outstanding voting stock of the
Corporation (other than a transaction effected primarily for the purpose of
changing the domicile of the Corporation), a sale of all or substantially all of
the assets of the Corporation, or a transaction or series of related
transactions (other than a public offering of the Corporation's securities,
following which a majority of the Board is comprised of those persons who were
members of the Board prior to such offering) in which the Corporation issues
shares representing more than fifty percent (50%) of the voting power of the
Corporation immediately after giving effect to such transaction, shall be
treated as a liquidation, dissolution or winding up for purposes of this Section
4. Any securities to be delivered to the holders of the Series A Preferred Stock
and Common Stock pursuant to such event shall be valued as follows:

                  (i)   Securities not subject to investment letter or other 
                        similar restrictions on free marketability:

                        (A)   If traded on a securities exchange or reported on
                              a national inter dealer quotation system, the
                              value shall be deemed to be the average of the
                              closing prices of the securities on such exchange
                              over the 30-day period ending three (3) days prior
                              to the closing;

                        (B)   If actively traded over the counter and not
                              reported on a national inter dealer quotation
                              system, the value shall be deemed to be the
                              average of the closing bid prices over the

                               

                                       14
<PAGE>   15
                              30-day period ending three (3) days prior to the
                              closing; and

                        (C)   If there is no active public market, the value
                              shall be the fair market value thereof, as
                              determined in good faith by the Board.

                  (ii)  The method of valuation of securities subject to
                        investment letter or other restrictions on free
                        marketability shall be to make an appropriate discount
                        from the market value determined as above in (i)(A), (B)
                        or (C) to reflect the approximate fair market value
                        thereof, as determined in good faith by the Board.

            (c) In the event of a transaction (or series of related
transactions) to be treated as a liquidation pursuant to this Section 4, the
Corporation shall give each holder of record of Series A Preferred Stock written
notice of such impending transaction not later than twenty (20) days prior to
the stockholders' meeting called to approve such transaction, or twenty (20)
days prior to the closing of such transaction, whichever is earlier, and shall
also notify such holders in writing of the final approval of such transaction.
The first of such notices shall describe the material terms and conditions of
the impending transaction and the provisions of this Section 4, and the
Corporation shall thereafter give such holders prompt notice of any material
changes. The transaction shall in no event take place sooner than twenty (20)
days after the Corporation has given the first notice provided for herein or
sooner than ten (10) days after the Corporation has given notice of any material
changes provided for herein; provided, however, that such periods may be
shortened upon the written consent of the holders of a majority of the shares of
Series A Preferred Stock.

      5. RESTRICTIONS AND LIMITATIONS. So long as any of the Series A Preferred
Stock remain outstanding, this corporation shall not, without first obtaining
the approval (by vote or written consent, as provided by law) of the holders of
at least a majority of the total number of shares of Series A Preferred Stock
outstanding:


            (i)   alter or change the rights, preferences or privileges of the
                  Series A Preferred Stock;

            (ii)  increase the aggregate number of authorized shares of Series A
                  Preferred Stock (other than an increase pursuant to a stock
                  split) or decrease the aggregate number of authorized shares
                  of Series A Preferred Stock below the number of shares of
                  Series A Preferred Stock then outstanding;

            (iii) authorize or issue, or obligate itself to issue, any other
                  equity security senior to or on a parity with the Series A
                  Preferred Stock as to dividends or assets in liquidation or
                  create or reclassify any obligation or security convertible
                  into or exchangeable for, or having any option rights to
                  purchase, any such equity security other than shares of
                  capital stock
                  

                                       15
<PAGE>   16
                  issuable upon conversion or exercise of securities outstanding
                  as of the Original Issue Date of the Series A Preferred Stock;

            (iv)  take any action which results in the redemption of, or payment
                  of dividends or the distribution of cash or any property with
                  respect to, any shares of Common Stock (other than pursuant to
                  (x) Section 4(a); (y) payments made to a stockholder who is
                  not a stockholder of the Corporation as of the Original Issue
                  Date of the Series A Preferred Stock in connection with an
                  acquisition or merger transaction by the Corporation which is
                  not deemed to be a liquidation pursuant to Section 4(b) above;
                  or (z) redemptions of employee or director owned stock or
                  options);

            (v)   incur or guarantee any indebtedness other than (a) in the
                  ordinary course of business; (b) under the Loan and Security
                  Agreement dated December 21, 1995, by and between Hayes
                  Microcomputer Products, Inc., an affiliate of the Corporation
                  and The CIT Group/Credit Finance, Inc., as amended thereafter,
                  or any replacement credit facility with a commercial lender
                  under which the Corporation or its subsidiaries maintains its
                  primary borrowing relationship; (c) indebtedness existing as
                  of the Original Issue Date of the Series A Preferred Stock;
                  (d) in an amount not to exceed $2,000,000 in the aggregate; or
                  (e) in connection with an acquisition or merger transaction by
                  the Corporation which is not deemed to be a liquidation under
                  Section 4(b) above; or

            (vi)  approve or create any mortgage, pledge or security interest in
                  all or substantially all of the assets or property of the
                  Corporation, except for such security interests or liens
                  arising under the Corporation's borrowings permitted under
                  Subsection 5(v) above.

      6. NO REISSUANCE OF SERIES A PREFERRED STOCK. No share or shares of Series
A Preferred Stock acquired by the Corporation by reason of purchase, conversion
or otherwise shall be reissued, and all such shares shall be canceled, retired
and eliminated from the shares which the Corporation shall be authorized to
issue. The corporation may, from time to time, take such appropriate corporate
action as may be necessary to reduce the authorized number of shares of the
Series A Preferred Stock, but not below the number of shares of such Series then
outstanding.

      7.    REDEMPTION.

            (a) Redemption Date. "Redemption Date" means April 23, 2000, or such
other date determined in accordance with Section 7(b) or 7(c) below.

            (b) Stockholder Redemption Request. Subject to the limitations set
forth herein and in Section 7(f) below, on ninety (90) days prior written notice
from the holders of more than fifty percent (50%) of the Series A Preferred
Stock ("Redemption Request") delivered

            

                                       16
<PAGE>   17
to the Corporation not earlier than November 1, 1999, the Corporation shall
redeem all of the shares of Series A Preferred Stock held by each holder as of
the date of such notice by paying in cash therefor, US $_________ [THIS BLANK
WILL EQUAL $20.9036 DIVIDED BY THE CONVERSION RATIO] per share of Series A
Preferred Stock (such amount to be adjusted proportionately in the event the
shares of Series A Preferred Stock are subdivided into a greater number or
combined into a lesser number and in the event the Corporation at any time pays
a dividend, or makes any other distribution, to holders of Series A Preferred
Stock payable in shares of Series A Preferred Stock) plus all accrued but unpaid
dividends on such shares (the "Redemption Price") on such Redemption Date.

            (c) Corporation Redemption Request. The corporation may, at its sole
option and discretion, at any time at which it has funds legally available to do
so, redeem all (or, if the holders of a majority of the outstanding Series A
Preferred Stock consent thereto, any part) of the Series A Preferred Stock upon
thirty (30) days prior written notice to the holders of the Series A Preferred
Stock, by paying the Redemption Price on the Redemption Date. Any partial
redemption hereunder shall be made pro rata among all holders of the Series A
Preferred Stock. Notwithstanding the foregoing, any holder of Series A Preferred
Stock may elect to convert to Common Stock all or any part of the Series A
Preferred Stock shares which the Corporation has elected to redeem by providing
written notice of its conversion election to the Corporation within twenty (20)
days after the date of the Corporation's redemption notice. In such event, those
shares of Series A Preferred Stock shall convert to Common Stock at the Series A
Conversion Price as provided in, and subject to the terms and conditions of
Section 3.

            (d) Surrender of Certificates. On or before the Redemption Date,
each holder of shares of Series A Preferred Stock being redeemed shall surrender
the certificate or certificates representing such shares to the Corporation, at
the Corporation's principal place of business. Upon such surrender (but not
earlier than the Redemption Date) the Redemption Price for such shares shall be
payable to the order of the person whose name appears on such certificate or
certificates as the owner thereof, and each surrendered certificate shall be
canceled and retired. If a certificate is surrendered and all the shares
evidenced thereby are not being redeemed, the Corporation shall cause
certificates evidencing the shares not being redeemed to be issued in the name
of the registered owner of such shares and to be delivered to such person.

            (e) Termination of Stock Rights. If the Corporation elects to redeem
the Series A Preferred Stock as provided above, or if a holder of Series A
Preferred Stock gives a Redemption Request and holds shares of Series A
Preferred Stock on the Redemption Date, and if on the Redemption Date the
Redemption Price is either paid or made available for payment through the
deposit arrangement specified in Section 7(f) below, then notwithstanding that
the certificates evidencing any of the shares of Series A Preferred Stock to be
redeemed shall not have been surrendered, all rights with respect to such shares
shall terminate as of the Redemption Date, except only the right of the holder
to receive the Redemption Price upon surrender of the certificate evidencing
such shares.

            (f) Deposit of Redemption Price. On or prior to a Redemption Date,
the Corporation shall deposit with any bank or trust company in the United
States having a capital


                                      17
<PAGE>   18
and surplus of at least US $50,000,000, as a trust fund, a sum equal to the
aggregate Redemption Price of all shares of Series A Preferred Stock to be
redeemed on the Redemption Date, with irrevocable instructions and authority to
the bank or trust company to pay, on or after the Redemption Date or prior
thereto, the Redemption Price to the respective holders upon the surrender of
their share certificates. From and after the date of such deposit ("Redemption
Deposit"), the shares so called for redemption shall be redeemed. The deposit
shall constitute full payment of the shares to their holders, and from and after
the Redemption Date the shares shall be deemed to be no longer outstanding, and
the holders thereof shall cease to be stockholders with respect thereto and
shall have no rights with respect thereto except the rights to receive from the
bank or trust company payment of the Redemption Price of the shares, without
interest, upon surrender of their certificates therefor. Any funds so deposited
and unclaimed at the end of one year from the Redemption Date shall be released
or repaid to the holders of the shares called for redemption shall be entitled
to receive payment of the Redemption Price with respect to such shares only from
the Corporation.

            (g) Insufficient Funds. If the funds of the Corporation legally
available therefor shall be insufficient to discharge the redemption
requirements under Section 7(b) in full due on any Redemption Date, funds to the
maximum extent legally available for such purpose shall be set aside on or
before the Redemption Date in accordance with Section 7(b). The maximum number
of full shares of Series A Preferred Stock that can be redeemed with such funds
shall be redeemed ratably from the holders of shares of Series A Preferred Stock
to be redeemed as of the Redemption Date. Thereafter, the Corporation shall
redeem shares of Series A Preferred Stock ratably from the holders thereof as
funds legally available therefor become available. Dividends shall continue to
accrue on shares of Series A Preferred Stock scheduled to be redeemed on a
Redemption Date but not yet redeemed until funds sufficient to redeem such
shares become legally available therefor and are paid or set aside in accordance
with this Section 7.

                                  ARTICLE VI

      The Board of Directors of the Corporation shall have the power to adopt,
amend or repeal Bylaws of the Corporation.

                                  ARTICLE VII

            The number of directors shall be fixed from time to time exclusively
by the Board of Directors pursuant to a resolution adopted by the affirmative
vote of a majority of the entire Board of Directors. The directors shall be
divided into three classes, designated as Class I, Class II and Class III. Each
class shall consist, as nearly as possible, of one-third of the total number of
directors, initially, with the directors of Class I elected for a term of one
year, the directors of Class II elected for a term of two years and the
directors of Class III elected for a term of three years. At each succeeding
annual meeting of stockholders following such classification and election,
directors elected to succeed those directors whose terms expire shall be elected
for a three-year term.



                                      18
<PAGE>   19
            Subject to the rights of the holders of any class or series of the
capital stock of the Corporation entitled to vote generally in the election of
directors (hereinafter in this Article VII and in the first proviso of Article
VIII of this Certificate of Incorporation, such stock is referred to as the
"Voting Stock") then outstanding, newly created directorships resulting from any
increase in the authorized number of directors or any vacancies in the Board of
Directors resulting from death, resignation, retirement, disqualification,
removal from office, or other cause may be filled only by a majority vote of the
directors then in office, though less than a quorum, and directors so chosen
shall hold office for a term expiring at the annual meeting of stockholders at
which the term of office of the class to which they have been elected expires.
No decrease in the number of authorized directors constituting the entire Board
of Directors shall shorten the term of any incumbent director. If the number of
directors is changed, any increase or decrease shall be apportioned among the
classes so as to maintain the number of directors in each class as nearly equal
as possible, and any additional director of any class elected to fill a vacancy
resulting from an increase in such class shall hold office for a term that shall
coincide with the remaining term of that class, but in no case will a decrease
in the number of directors shorten the term of any incumbent director. A
director shall hold office until the annual meeting for the year in which his
term expires and until his successor shall be elected and shall qualify,
subject, however, to prior death, resignation, retirement, disqualification or
removal from office.

            Subject to the rights of the holders of any class or series of the
Voting Stock then outstanding, any director, or the entire Board of Directors,
may be removed from office at any time, but only for cause and only by the
affirmative vote of the holders of at least 80% of the voting power of all of
the then-outstanding shares of the Voting Stock, voting together as a single
class (it being understood that, for all purposes of this Article VII, and the
provisions of the By-Laws of the Corporation which require the affirmative vote
of the holders of at least 80% of the voting power of all of the
then-outstanding shares of the Voting Stock, voting together as a single class,
to alter, amend or repeal any provision of the By-Laws which is to the same
effect as the provisions of this Certificate of Incorporation enumerated in the
first proviso of Article VIII hereof, each share of the Voting Stock shall have
the number of votes granted to it pursuant to Article V of this Certificate of
Incorporation or any designation of the rights, powers and preferences of any
class or series of Preferred Stock made pursuant to said Article IV (a
"Preferred Stock Designation")).

            Notwithstanding any other provisions of this Certificate of
Incorporation or any provision of law which might otherwise permit a lesser vote
or no vote, but in addition to any affirmative vote of the holders of any
particular class or series of the Voting Stock required by law, this Certificate
of Incorporation or any Preferred Stock Designation, the affirmative vote of the
holders of at least 80% of the voting power of all of the then-outstanding
shares of the Voting Stock, voting together as a single class, shall be required
to alter, amend or repeal this Article VII.

            Notwithstanding the foregoing, whenever the holders of any one or
more classes or series of Preferred Stock issued by the Corporation shall have
the right, voting separately by class or series, to elect directors at an annual
or special meeting of stockholders, the election, term of office, filling of
vacancies and other features of such directorships shall be governed by 



                                      19
<PAGE>   20
the terms of this Certificate of Incorporation applicable thereto (including the
resolutions of the Board of Directors pursuant to Article IV), and such
Directors so elected shall not be divided into classes pursuant to this Article
VII unless expressly provided by such terms.

                                 ARTICLE VIII

            In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized:

                  To make, alter or repeal the bylaws of the Corporation;
            provided, however, that notwithstanding any other provisions of the
            Certificate of Incorporation or any provision of law which might
            otherwise permit a lesser vote or no vote, but in addition to any
            affirmative vote of the holders of any particular class or series of
            the Voting Stock required by law, this Certificate of Incorporation
            or any Preferred Stock Designation, the affirmative vote of the
            holders of at least 80% of the voting power of all of the
            then-outstanding shares of the Voting Stock, voting together as a
            single class, shall be required to alter, amend or repeal (i) any
            provision of the By-laws which is to the same effect as Article VII
            of this Certificate of Incorporation, or (ii) this proviso of this
            Article VIII.

                  To authorize and cause to be executed mortgages and liens upon
            the real property of the Corporation.

                  To set apart out of any of the funds of the Corporation
            available for dividends a reserve or reserves for any proper purpose
            and to abolish any such reserve in the manner in which it was
            created.

                  By a majority of the whole board, to designate one or more
            committees, each committee to consist of one or more of the
            directors of the Corporation.

                  When and as authorized by the stockholders in accordance with
            this Certificate of Incorporation and applicable statutes, to sell,
            lease or exchange all or substantially all of the property and
            assets of the Corporation, including its goodwill and its corporate
            franchises, upon such terms and conditions and for such
            consideration (which may consist, in whole or in part, of money or
            property, including shares of stock in, and/or other securities of,
            any other corporation or corporations) as the Corporation's Board of
            Directors shall deem appropriate and in the best interests of the
            Corporation.

                                  ARTICLE IX

      To the fullest extent permitted by law, no director of the Corporation
shall be personally liable for monetary damages for breach of fiduciary duty as
a director. Without limiting the effect of the preceding sentence, if the
Delaware General Corporation Law is hereafter amended to authorize the further
elimination or limitation of the liability of a director, then the liability of
a director of the Corporation shall be eliminated or limited to the fullest
extent permitted by the Delaware General Corporation Law, as so amended.

      Neither any amendment nor repeal of this Article IX, nor the adoption of
any provision of this Restated Certificate of Incorporation inconsistent with
this Article IX, shall eliminate, reduce or otherwise adversely affect any
limitation on the personal liability of a director of the Corporation existing
at the time of such amendment, repeal or adoption of such an inconsistent
provision.

      This Amended and Restated Certificate of Incorporation was duly adopted in
accordance with the provisions of Section 245 of the General Corporation Law of
the State of Delaware.

      IN WITNESS WHEREOF, this Amended and Restated Certificate of Incorporation
has been duly executed by the Corporation as of the ____ day of _________, 1997.

                                    ARTICLE I

         SECTION 2. DATE, HOUR AND PURPOSE OF ANNUAL MEETINGS OF STOCKHOLDERS.
Annual meetings of Stockholders, commencing with the year 1996, shall be held on
such day and at such time as the Directors may determine from time to time by
resolution, at which meeting the stockholders shall elect, by a plurality of the
votes cast at such election, a Board of Directors, and transact such other
business as may properly be brought before the meeting in accordance with these
Bylaws. To be properly brought before the annual meeting, business must be
either (i) specified in the notice of annual meeting (or any supplement or
amendment thereto) given by or at the direction of the Board of Directors, (ii)
otherwise brought before the annual meeting by or at the direction of the Board
of Directors, or (iii) otherwise properly brought before the annual meeting by a
stockholder. In addition to any other applicable requirements, for business to
be properly brought before an annual meeting by a stockholder, the stockholder
must have given timely notice thereof in writing to the Secretary of the
Corporation. To be timely, a stockholder's notice must be delivered to or mailed
and received at the principal executive offices of the Corporation not less than
sixty (60) days prior to the meeting; provided, however, that in the event that
less than seventy (70) days notice or prior public disclosure of the date of the
annual meeting is given or made to stockholders, notice by a stockholder, to be
timely, must be received no later than the close of business on the tenth (10th)
day following the day on which such notice of the date of the annual meeting was
mailed or such public disclosure was made, whichever first occurs. A
stockholder's notice to the Secretary shall set forth (a) as to each matter the
stockholder proposes to bring before the annual meeting (i) a brief description
of the business desired to be brought before the annual meeting and the reasons
for conducting such business at the annual meeting, and (ii) any material
interest of the stockholder in such business, and (b) as to the stockholder
giving the notice (i) the name and record address of the stockholder and (ii)
the class, series and number of shares of capital stock of the Corporation which

Article II, Section 2. The officer of the Corporation presiding at an annual
meeting shall, if the facts warrant, determine and declare to the annual meeting
that business was not properly brought before the annual meeting in accordance
with the provisions of this Article II, Section 2, and if such officer should so
determine, such officer shall so declare to the annual meeting and any such
business not properly brought before the annual meeting shall not be transacted.

         If for any reason a Board of Directors shall not be elected at the
Annual Meeting of Stockholders, or if it appears that such Annual Meeting is not
held on such date as may be fixed by the Directors in accordance with the

expressly required or permitted by the laws of Delaware, not less than ten (10)
days nor more than sixty (60) days before the date of every stockholders'
meeting the Secretary shall give to each stockholder of record entitled to vote
at such meeting written notice stating the place, day and hour of the meeting
and, in the case of a special meeting, the purpose or purposes for which the
meeting is called. Such notice, if mailed, shall be deemed to be given when
deposited in the United States mail, with postage thereon prepaid, addressed to
the stockholder at the post office address for notices to such stockholder as it
appears on the records of the Corporation.

         An Affidavit of the Secretary or an Assistant Secretary or of a
transfer agent of the Corporation that the notice has been given shall, in the
absence of fraud, be prima facie evidence of the facts stated therein.

         SECTION 5. QUORUM OF STOCKHOLDERS.

                  (a)      Unless otherwise provided by the laws of Delaware,
         at any meeting of the stockholders the presence in person or

         be present, a majority of those present in person or by proxy may
         adjourn the meeting from time to time without notice other than
         announcement at the meeting. In the absence of a quorum, the officer
         presiding thereat shall have power to adjourn the meeting from time to

         present, any business may be transacted which might have been
         transacted at the meeting originally called, but only those
         stockholders entitled to vote at the meeting as originally noticed
         shall be entitled to vote at any adjournment or adjournments thereof,
         unless a new record date is fixed by the Board of Directors.

                  (d) If an adjournment is for more than thirty (30) days, or if
         after the adjournment a new record date is fixed for the adjourned
         meeting, a notice of the adjourned meeting shall be given to each
         stockholder of record entitled to vote at the adjourned meeting.

         SECTION 6. CHAIRMAN AND SECRETARY OF MEETING. The Chairman, or in his
absence, the Vice Chairman, or in his absence, the President, or in his absence,
any Vice President, shall preside at meetings of the stockholders. The Secretary

person to act as secretary of the meeting.

         SECTION 7. VOTING BY STOCKHOLDERS. Except as may be otherwise provided
by the Certificate of Incorporation or by these Bylaws, at every meeting of the
stockholders each stockholder shall be entitled to one vote for each share of
stock standing in his name on the books of the Corporation on the record date
for the meeting. All elections and questions shall be decided by the vote of a
majority in interest of the stockholders present in person or represented by
proxy and entitled to vote at the meeting, except as otherwise permitted or
required by the laws of Delaware, the Certificate of Incorporation or these
Bylaws.

         SECTION 8. PROXIES. Any stockholder entitled to vote at any meeting of

         stockholders, the Secretary shall prepare or cause to be prepared a
         complete list of the stockholders entitled to vote at the meeting,
         arranged in alphabetical order and showing the address of each
         stockholder and the number of shares registered in the name of each

                  (c) The list shall also be produced and kept at the time and
         place of the meeting during the whole time of the meeting, and it may

         the stockholders entitled to examine the stock ledger, the list
         required by this Section or the books of the Corporation, or to vote in
         person or by proxy at any meeting of stockholders.

                                   ARTICLE II
                                    DIRECTORS

         SECTION 1. POWERS OF DIRECTORS. The property, business and affairs of
the Corporation shall be managed by its Board of Directors, which may exercise
all the powers of the Corporation except such as are by the laws of Delaware or
the Certificate of Incorporation or these Bylaws required to be exercised or
done by the stockholders.

         SECTION 2. NOMINATION OF DIRECTORS. Nominations of persons for election
to the Board of Directors at the annual meeting may be made at such meeting by
or at the direction of the Board of Directors, by any committee or persons
appointed by the Board of Directors or by any stockholder of the Corporation
entitled to vote for the election of directors at the meeting who complies with
the notice procedures set forth in this Article III, Section 2. Such nominations
by any stockholder shall be made pursuant to timely notice in writing to the
Secretary of the Corporation. To be timely, a stockholder's notice shall be
delivered to or mailed and received at the principal executive offices of the
Corporation not less than sixty (60) days prior to the meeting; provided
however, that in the event that less than

                                       4
<PAGE>   5

seventy (70) days notice or prior public disclosure of the date of the meeting
is given or made to stockholders, notice by the stockholder, to be timely, must
be received no later than that the close of business on the tenth (10th) day
following the day on which such notice of the date of the meeting was mailed or
such public disclosure was made, whichever first occurs. Such stockholder's
notice to the Secretary shall set forth (a) as to each person whom the
stockholder proposes to nominate for election or reelection as a director, (i)
the name, age, business address and residence address of the person, (ii) the
principal occupation or employment of the person, (iii) the class and number of
shares of capital stock of the Corporation which are beneficially owned by the
person, and (iv) any other information relating to the person that is required

stockholder giving the notice (i) the name and record address of the stockholder
and (ii) the class and number of shares of capital stock of the Corporation
which are beneficially owned by the stockholder. The Corporation may require any
proposed nominee to furnish such other information as may reasonably be required
by the Corporation to determine the eligibility of such proposed nominee to
serve as a director of the Corporation. No person shall be eligible for election
as a director of the Corporation unless nominated in accordance with the
procedures set forth herein. The officer of the Corporation presiding at an
annual meeting shall, if the facts warrant, determine and declare to the meeting
that a nomination was not made in accordance with the foregoing procedure, and
if he should so determine, he shall so declare to the meeting and the defective
nomination shall be disregarded. The directors shall be elected at the annual
meeting of the stockholders, except as provided in the Certificate of
Incorporation, and each director elected shall hold office until his successor
is elected and qualified; provided, however, that unless otherwise restricted by
the Certificate of Incorporation or by law, any director or the entire Board of
Directors may be removed, either with or without cause, from the Board of
Directors at any meeting of stockholders by a majority of the stock represented
and entitled to vote thereat.

         SECTION 3. VACANCIES ON BOARD OF DIRECTORS. Any Director may resign his
office at any time by delivering his resignation in writing to the Chairman or
the President or the Secretary. It will take effect at the time specified
therein, or if no time is specified, it will be effective at the time of its
receipt by the Corporation. The acceptance of a resignation shall
not be necessary to make it effective, unless expressly so provided
in the resignation.

   and special, either within or outside the State of Delaware.

   notice at such time and place as shall from time to time be determined by
   resolution of the Board of Directors.

         (c)      The first meeting of each newly elected Board of Directors
   except the initial Board of Directors shall be held as soon as practicable
   after the Annual Meeting of the stockholders for the election of officers and
   the transaction of such other business as may come before it.

         (d)      Special meetings of the Board of Directors shall be held
   whenever called by direction of the Chairman, the Chief Executive Officer,
   the President or at the request of Directors constituting one-third of the
   number of Directors then in office, but not less than two Directors.

         (e)      The Secretary shall give notice to each Director of any
   meeting of the Board of Directors by mailing the same at least two days
   before the meeting or by telegraphing or delivering the same not later than
   the day before the meeting. Such notice need not include a statement of the
   business to be transacted at, or the purpose of, any such meeting. Any and
   all business may be transacted at any meeting of the Board of Directors. No
   notice of any adjourned meeting need be given. No notice to or waiver by any
   Director shall be required with respect to any meeting at which the Director
   is present.

         SECTION 5. QUORUM AND ACTION. A majority of the entire Board of
Directors shall constitute a quorum for the transaction of business; but if
there shall be less than a quorum at any meeting of the Board, a majority of

                  indirectly, on Executive's own behalf or on behalf of others,
                  solicit, divert, or appropriate any business for the

                  with those manufactured, assembled or sold by the Company,
                  from any customer or actively sought prospective customer of
                  the Company to whom the Company offered or provided products
                  or services, and with whom Executive had material contact at
                  any time during the twenty-four (24) months preceding the
                  termination of Executive's employment.

                  (iii)    Covenant Not to Solicit Employees. During the term of
                  Executive's employment hereunder, and for a period of two (2)
                  years following the termination of such employment for any
                  reason whatsoever, Executive shall not employ or solicit the
                  employment of any employee of the Company who was an employee
                  of the Company at any time during the six (6) months preceding
                  the termination of Executive's employment with the Company,
                  for the purpose of causing such employee to take employment
                  with Executive or a competitor of the Company.

                  Executive agrees and acknowledges that the restrictions in
this Agreement are not vague, over broad or indefinite, and are reasonable and
designed to protect the legitimate business interests of the Company. In

of any or all of said covenants, Company shall be entitled to injunctive and/or
other equitable relief against Executive for any violation of any of said
Covenants.

any provisions of the Company's Operations Policies expressly or by necessary
implication applicable after the termination of employment, shall survive
termination of this Agreement. Upon termination, Executive shall repay to

advance, it being the intent of the parties that all such advances shall be
repayable as provided by this paragraph. Company may offset any sums owed to
Company by Executive against any amounts otherwise owed by Company to Executive.

                         EXECUTIVE EMPLOYMENT AGREEMENT

                  This Executive Employment Agreement (this "Agreement") is
entered into by and between Hayes Microcomputer Products, Inc. (the "Company")
and Keith Mintzer (the "Executive") on this 20th day of December, 1996.

                  For and in consideration of the employment or continued
employment, as the case may be, of the Executive by the Company, the mutual
covenants and promises contained herein, and in the Terms and Conditions of
Employment attached hereto as Exhibit "A," and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
Company and the Executive hereby covenant and agree as follows:

                  1.       Employment; Compensation. Company hereby employs or
continues to employ Executive as Vice President of Sales on the terms and
conditions set forth herein and Executive accepts such employment. Executive's
initial base salary shall be One Hundred Seventy Five Thousand and no/100
Dollars ($175,000.00) per year, and, subject to the provisions below, shall
continue for so long as Executive is employed by the Company, or until such
salary is modified by mutual consent of the parties hereto. The Company shall
review Executive's performance and salary annually. Executive shall be entitled
to receive bonuses in accordance with the Company's normal policies with respect
to similarly situated Executives, if any. In addition, Executive will be
entitled to receive further consideration, if any, pursuant to the Variable
Compensation Plan executed on or before the effective date hereof.

                  2.       Term. Following execution, this Agreement shall
become effective January 6, 1997. The Term of this Agreement shall be two (2)
years from the effective date, unless sooner terminated in accordance with
paragraph 3 below, or if the events occur and Executive chooses to resign as set
forth in paragraph 4 below.

                  3.       Termination and Severance. This Agreement may be
terminated by Company, its Chairman of the Board, its Chief Executive Officer,
or Executive with or without Cause. In the event Company, the Chairman of the
Board, or the Chief Executive Officer terminates this Agreement without Cause
during the Term, or if the events occur as set forth in paragraph 4 below during
the term, then Executive shall be entitled to severance pay in the form of
continuation of his base salary for six (6) months following the date of
termination ("Severance Pay"). In the event that Company, the Chairman of the
Board, or the Chief Executive Officer terminates Executive's employment for
Cause, or Executive voluntarily terminates employment other than for the events
set forth in paragraph 4 below, or the Term expires, the Company shall not be
obligated to pay any salary or other Compensation to Executive, including
Severance Pay, after the effective date of termination or resignation. Executive
agrees to provide Company with at least six (6) weeks advance written notice
prior to voluntary termination or resignation by Executive.

                  4.       Change in Control. If any of the events constituting
a Change in Control of the Company shall have occurred, Employee shall be
entitled to two times Severance Pay (or continuation of his base salary for
twelve (12) months ) upon termination of employment, or resignation of
employment for Good Reason, before the first anniversary of the date of such a
Change in Control of the Company and during the term, unless such termination is
(a) due to Executive's death, (b) because of Executive's incapacity due to
physical or mental illness, or (c) by the Company for Cause, or unless such
resignation is for something other than Good Reason. In the event Executive's
employment with the Company is terminated for any reason prior to a Change in
Control (provided that such termination did not occur during


<PAGE>   2



the pendency of a Potential Change in Control) and subsequently a Change in
Control occurs, Employee shall not be entitled to Severance Pay under this
paragraph 4.

                  5.       Successors. The Company will require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business and/or assets of the Company to
expressly assume and agree to perform this Agreement in the same manner and to
the same extent that the Company could be required to perform this Agreement if
no such succession had taken place. Failure of the Company to obtain such
assumption and agreement prior to the effectiveness of any such succession shall
be a breach of this Agreement and shall entitle Executive to compensation from
the Company in the same amount and on the same terms to which Executive would be
entitled hereunder. As used in this Agreement, "Company" shall mean the Company
as hereinbefore defined and any successor to its business and/or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of law
or otherwise.

                  6.       Terms and Conditions. Executive acknowledges that
this Agreement, and his employment obligations hereunder, expressly include the
provisions set forth in the Terms and Conditions of Employment attached hereto
as Exhibit "A," which are incorporated herein by this reference thereto. This
Agreement shall supersede any prior employment agreement, and any restrictive
covenants, previously entered into by Executive with the Company.

                  IN WITNESS WHEREOF, the parties hereto have set their hands
and seals on the date and year first above written.

         5.       Protective Covenants. Executive is and will during the course
of employment become intimately familiar with Confidential Information, trade
secrets, facilities and services, and other property of the Company, and the
protection of the Company requires that all such property and information must

Company's benefit, not to be disclosed to any other party or used by Executive
against Company. Accordingly, Executive does hereby warrant, represent, covenant
and agree, as follows:

                  (i)      Covenant Not to Compete. Executive agrees that, for a

                  with Company, whether with or without Cause, he shall not,

                  or selling of products competitive with those designed,
                  manufactured, assembled, or sold by the Company at the time of
                  the termination of employment, in a capacity which requires
                  Executive to perform services substantially identical to the
                  services performed by Executive on behalf of Company.



<PAGE>   4



                  (ii)     Covenant Not to Solicit Customers. During the term of
                  Executive's employment hereunder, and for a period of one (1)
                  years following the termination of such employment for any
                  reason whatsoever, Executive shall not (except on behalf of or
                  with the prior written consent of Company), either directly or
                  indirectly, on Executive's own behalf or on behalf of others,
                  solicit, divert, or appropriate any business for the
                  manufacture, assembling, or sale of products competitive with
                  those manufactured, assembled or sold by the Company, from any
                  customer or actively sought prospective customer of the
                  Company to whom the Company offered or provided products or
                  services, and with whom Executive had material contact at any
                  time during the twelve (12) months preceding the termination
                  of Executive's employment.

                  (iii)    Covenant Not to Solicit Employees. During the term of
                  Executive's employment hereunder, and for a period of one (1)
                  year following the termination of such employment for any
                  reason whatsoever, Executive shall not employ or solicit the
                  employment of any employee of the Company who was an employee
                  of the Company at any time during the six (6) months preceding
                  the termination of Executive's employment with the Company,
                  for the purpose of causing such employee to take employment
                  with Executive or a competitor of the Company.

                  Executive agrees and acknowledges that the restrictions in
this Agreement are not vague, over broad or indefinite, and are reasonable and
designed to protect the legitimate business interests of the Company. In
addition to any other remedies which Company may have under the law for breach
of any or all of said covenants, Company shall be entitled to injunctive and/or
other equitable relief against Executive for any violation of any of said
Covenants.

         6.       Survival. Paragraphs 2, 3, 4, 5, and 6 hereof, together with
any provisions of the Company's Operations Policies expressly or by necessary
implication applicable after the termination of employment, shall survive
termination of this Agreement. Upon termination, Executive shall repay to
Company immediately any advances by Company, not offset by earnings or other
credits due him or her, even if not expressly made repayable at the time of such
advance, it being the intent of the parties that all such advances shall be
repayable as provided by this paragraph. Company may offset any sums owed to
Company by Executive against any amounts otherwise owed by Company to Executive.
No sums otherwise due Executive at termination shall be payable to Executive if,
at the time of termination or thereafter, Executive shall be in violation of any
term or provision of this Agreement.

         7.       Entire Agreement. This Agreement contains the entire
understanding and agreement between the parties, and all promises,
representations, warranties or inducements made by either party to the other,
including any prior employment agreement or restrictive covenants, not
specifically made in writing or made a part hereof by reference, are expressly
superseded and shall have no force or effect. This Agreement may not be modified
except in a writing signed by both parties hereto.

         8.       Severability. If any provision of this Agreement (including
any subparts of any paragraph) is invalid or unenforceable by any rule of law or
public policy, this Agreement shall be construed so as to delete herefrom the
invalid or unenforceable covenant or provision. To the extent that any provision
is invalid or unenforceable that may be valid or enforceable by limitation
thereof, then such provision shall be enforceable to the fullest extent
permitted under the law of the jurisdiction in which enforcement is sought. If
any particular provision is held to be invalid, illegal or unenforceable, all
other covenants, terms, conditions and provisions hereof shall be and remain in
full force and effect.

                  performed by Executive on behalf of Company.

                  (ii)     Covenant Not to Solicit Customers. During the term of

                  or services, and with whom Executive had material contact at
                  any time during the twenty-four (24) months preceding the

                  the termination of Executive's employment with the Company,
                  for the purpose of causing such employee to take employment
                  with Executive or a competitor of the Company.

                  Executive agrees and acknowledges that the restrictions in
this Agreement are not vague, over broad or indefinite, and are reasonable and
designed to protect the legitimate business interests of the Company. In
addition to any other remedies which Company may have under the law for breach
of any or all of said covenants, Company shall be entitled to injunctive and/or
other equitable relief against Executive for any violation of any of said
Covenants.

any provisions of the Company's Operations Policies expressly or by necessary
implication applicable after the termination of employment, shall survive
termination of this Agreement. Upon termination, Executive shall repay to

credits due him or her, even if not expressly made repayable at the time of such
advance, it being the intent of the parties that all such advances shall be
repayable as provided by this paragraph. Company may offset any sums owed to
Company by Executive against any amounts otherwise owed by Company to Executive.

at the time of termination or thereafter, Executive shall be in violation
of any term or provision of this Agreement.

                                     - 5 -

<PAGE>   6



Preferred Shares to any Person unless the Shareholder seeking to make the
transfer (the "Transferor") shall first have made the written offer to sell
described in Section 4.2 below (the "Offer") and that Offer has not been
accepted pursuant to the terms of this Shareholders' Agreement.

                  4.2. Offer by Transferor. The Offer referred to in Section
4.1 shall be given by the Transferor to the Company and to each of the other
Shareholders (,herein the "Non-Offering Shareholders") and shall consist of a
written Offer to sell all the Offered Shares which the Transferor then intends
to dispose of, to which Offer shall be attached a statement of intention to
dispose of the Offered Shares pursuant to a bona fide offer from a prospective
purchaser or purchasers (the "Transferee"), a description of the contemplated
disposition, the name and address of each bona fide Transferee, the number of
Preferred Shares involved in and other terms (the "Terms") of the proposed
disposition. The Terms shall include, without limitation, the purchase price
per Offered Share offered by each Transferee and the manner in which such
purchase price shall be paid to the Transferor. Such Offer shall be signed by
the Transferor and shall remain irrevocable until the earlier of (a) the time
at which all of the Offered Shares are accepted by the Company or the Non-
Offering Shareholders, as provided in Sections 4.3 and 4.4 or (b) one hundred
twenty (120) days after the "Offer Date," which date shall be the date on which
a notice is given to the Company and such Non-Offering Shareholders in
accordance with the terms of Section 12.1 of this Shareholders' Agreement. The
date on which the Offer becomes revocable is referred to herein as the
"Expiration Date."

                  4.3. Acceptance of Offer by the Company. The Company may, at
its option exercise within sixty (60) days after the Offer Date, elect to
purchase all or any portion of the Offered Shares on the Terms (with the
designees of the selling Shareholder abstaining on any vote of the Board of
Directors of the Company with respect to such purchase). If and to the extent
the Company does not accept the Offer in accordance with this Section 4.3 with
respect to all of the Offered Shares, the Offered Shares may be disposed of in
accordance with Section 4.4. The Company shall exercise its option under this
Section 4.3 by giving an Exercise Notice. The Exercise Notice shall be in
accordance with the Terms. Any purchase by the Company of one hundred percent
(100%) of the Offered Shares shall be completed not later than ninety (90) days
after the Offer Date (subject to any extension of time required to permit
necessary governmental or regulatory filings, notices or approvals).

                  4.4. Acceptance of Offer by Shareholders. If and to the
extent the Company does not accept the Offer with respect to all of the Offered
Shares in accordance with the provisions of Section 4.3, the remaining Offered
Shares shall be deemed to be offered to the Non-Offering Shareholders and each
Non-Offering Shareholder may, at its option exercised within ten (10) days
after (i) the last day of the exercise period pursuant to Section 4.3 or, if
earlier (ii) the date on which the Company notifies the Shareholders of its
election to purchase less than all (or none) of the Offered Shares, elect to
purchase not more than its Proportion of the remaining Offered Shares. Each
Non-Offering Shareholder who exercises its option to purchase its Proportion of
the Offered Shares shall do so by giving an Exercise Notice. In the event that
any such Non-Offering Shareholder gives an Exercise Notice covering less than
its Proportion of the Offered Shares


                                     - 6 -

<PAGE>   7



available to be purchased by Non-Offering Shareholders (such shares not covered
by Exercise Notices being referred to as the "Balance"), each of the
Non-Offering Shareholders that time delivered an Exercise Notice covering its
full Proportion of the Offered Shares available to be purchased by Non-Offering
Shareholders, may, by a second Exercise Notice delivered within ten (10) days
after the expiration of the first ten (10) day period referred to above, elect
to purchase up to that number of Offered Shares that is equal to the product of
the Balance multiplied by a fraction, the numerator of which shall be such
Non-Offering Shareholder's Proportion of the number of Offered Shares first
made available for purchase by Non-Offering Shareholders pursuant to this
Section 4.4, and the denominator of which shall be the total number of such
Offered Shares covered by the first Exercise Notices timely delivered by all
Non-Offering Shareholders which purchased their respective full Proportions.
If, after the expiration of the second ten (10) day period any Offered Shares
remain available to be purchased, any Non-Offering Shareholder which has timely
delivered Exercise Notices covering the maximum number of Offered Shares
available to it, may notify the Company, within five (5) days after the
expiration of such second ten (10) day period of its desire to purchase
additional Offered Shares, specifying the maximum number of such Offered Shares
it is willing to purchase. If more than one such notice is received by the
Company, the number of additional Offered Shares shall be allocated to the
Non-Offering Shareholders delivering such notices in the same proportion as
their respective offers bear to the total number of Offered Shares available in
the third and final round.

                  4.5. Purchases by Company and Shareholders. If the Company
and the Non- Offering Shareholders together, or the Non-Offering Shareholders
(or any of them) alone, elect to purchase 100% of the Offered Shares, the sale
and purchase of such shares shall be completed not later than one hundred and
five (105) days after the Offer Date (subject to any extension of time required
to permit necessary governmental or regulatory filings, notices or approvals).
The Transferor shall not be obligated to sell any Offered Shares to the Company
or to any Non-Offering Shareholder unless the Company and/or the Non-Offering
Shareholders have agreed to purchase, and purchase, 100% of the Offered Shares.
"Completion" of any sale pursuant to this Article 4 shall mean, at a minimum,
delivery by the selling Shareholder to each purchaser of certificate(s)
representing the number of Preferred Shares to be sold, in form for transfer by
delivery, and payment by each purchaser of the purchase price therefor in
accordance with the Terms, or as may otherwise be agreed by the parties.

         5.       SALE OF OFFERED SHARES TO TRANSFEREE.

         If the Non-Offering Shareholders and the Company do not elect to
purchase all of the Offered Shares in accordance with the terms of Sections 4.3
and 4.4 the Transferor shall not be obligated to sell any of the Offered Shares
to the Non-Offering Shareholders or the Company and shall be entitled to
dispose of all of the Offered Shares to the Transferee on the Terms, provided
that such disposition is consummated within one hundred fifty (150) days
(subject to any extension of time required to permit necessary governmental or
regulatory filings, notices or approvals) after the Offer Date and the
Transferee executes a counterpart of this Shareholders' Agreement and agrees to
remain bound by all terms of this Shareholders' Agreement. Any proposed
transfer on terms and conditions


                                     - 7 -

<PAGE>   8



other than the Terms, as well as any subsequent proposed transfer of Preferred
Shares by such Shareholder, shall again be subject to the rights of the Company
and the Non-Offering Shareholders and shall require compliance by Transferor
with the procedures described in Article 4.

         6.       EFFECTS OF NON-PARTICIPATION.

         The exercise or non-exercise of the rights of any Shareholder or the
Company under Article 4 to participate in one or more sales of shares of Stock
made by the Company or any Shareholder shall not adversely affect such
Shareholder's or the Company's right, as applicable, to participate in
subsequent sales of shares of Stock subject to Article 4.

         7.       REGISTRATION RIGHTS.

                  7.1. Company Registration. If at any time after the date of
this Shareholders' Agreement the Company proposes to register (including for
this purpose a registration effected by the Company for shareholders other than
the Holders) any of its stock or other securities under the Securities Act in
connection with the public offering of such securities solely for cash (other
than a registration relating solely to the sale of securities to participants
in a Company stock plan, or a registration relating to shares to be issued in
connection with the acquisition of another company, or a registration on any
form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder made within (30) days after the Company shall have given such notice in
accordance with Section 12.1 hereof, the Company shall, subject to the
provisions of Section 7.5, use all reasonable efforts to cause to be registered
under the Securities Act all of the Registrable Securities that each such
Holder has requested to be registered.

                  7.2. Obligations of the Company. Whenever required under this
Article 7 to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                  (a)  Prepare and file with the SEC a registration statement
         with respect to such Registrable Securities and use all reasonable
         efforts to cause such registration statement to become effective, and,
         upon the request of the Holders of a majority of the Registrable
         Securities registered thereunder, keep such registration statement
         effective for up to one hundred twenty (120) days;

                  (b)  Prepare and file with the SEC such amendments and
         supplements to such registration statement and the prospectus used in
         connection with such registration statement as may be necessary to
         comply with the provisions of the Securities Act with respect to the
         disposition of all securities covered by such registration statement;


                                     - 8 -

<PAGE>   9



                  (c)  Furnish to the Holders such numbers of copies of a
         prospectus, including a preliminary prospectus, in conformity with the
         requirements of the Securities Act, and such other documents as they
         may reasonably request in order to facilitate the disposition of
         Registrable Securities owned by them;

                  (d)  Use all reasonable efforts to register and qualify the
         securities covered by such registration statement under such other
         securities or blue sky laws of such jurisdictions as shall be
         reasonably requested by the Holders, provided, however, that the
         Company shall not be required in connection therewith or as a
         condition thereto to qualify to do business or to file a general
         consent to service of process in any such states or jurisdictions; and

                  (e)  Enter into and perform its obligations under an
         underwriting agreement, in usual and customary form, with the managing
         underwriter of such offering. Each Holder participating in such
         underwriting shall also enter into and perform its obligations under
         such an agreement.

                  7.3. Furnish Information. It shall be a condition precedent
to the obligations of the Company to take any action pursuant to this Article 7
that the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them, and the intended
method of disposition of such securities as shall be reasonably and customarily
required to effect the registration of the Registrable Securities.

                  7.4. Expenses of Company Registration. The Company shall bear
and pay all, expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 7.1 for each Holder (which right may be assigned as
provided in Section 7.10), including (without limitation) all registration,
filing and qualification fees, printers' and accounting fees relating or
apportionable thereto and the reasonable fees and disbursements (not to exceed
US $50,000) of one counsel for the selling Holders selected by them, but
excluding underwriting discounts and commissions relating to Registrable
Securities.

                  7.5. Underwriting Requirements. In connection with any
offering involving an underwriting of shares being issued by the Company, the
Company shall not be required under Section 7.1 to include any of the Holders'
securities in such underwriting unless such Holder accepts the terms of the
underwriting as agreed upon between the Company and the underwriters selected
by the Company, and then only in such quantity as will not, in the opinion of
the underwriters, jeopardize the success of the offering by the Company. If the
total amount of securities, including Registrable Securities, requested by
shareholders to be included in an offering exceeds the amount of securities to
be sold other than by the Company that the underwriters reasonably believe
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of Registrable Securities which the
underwriters believe will not jeopardize the success of the offering (the
securities so included to be apportioned pro rata among the selling
shareholders according to the total amount of securities requested to be
included therein

                                     - 9 -

<PAGE>   10



owned by each selling shareholder or in such other proportions as shall
mutually be agreed to by such selling shareholders).

                  If any Person does not agree to the terms of any such
underwriting, it shall be excluded therefrom by written notice from the Company
or the underwriter. Any Registrable Securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration. If shares are so
withdrawn from the registration, the Company shall then offer to all Persons
who have retained the right to include securities in the registration the right
to include additional securities in the registration in an aggregate amount
equal to the number of shares so withdrawn, with such shares to be allocated
among the Persons requesting additional inclusion pro rata according to the
total amount of securities requested to be included in such registration owned
by each such Person or in such other proportions as shall be mutually agreed by
such selling shareholders.

                  For purposes of the immediately preceding paragraph
concerning apportionment, for any selling shareholder which is a holder of
Registrable Securities and which is a partnership or corporation, the partners,
retired partners and shareholders of such Holder, or the estates and family
members of any such partners and retired partners, and any trusts for the
benefit of any of the foregoing Persons shall be deemed to be a single "selling
shareholder," and any pro rata reduction with respect to such "selling
shareholder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"selling shareholder," as defined in this sentence.

                  7.6. Delay of Registration. No Holder shall have any right to
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Article 7.

                  7.7. Indemnification. In the event any Registrable Securities 
are included in a registration statement under this Article 7:

                  (a)  To the extent permitted by law, the Company will
         indemnify and hold harmless each Holder, the officers, directors,
         partners, employees and legal counsel of each Holder, and each Person,
         if any, who controls such Holder within the meaning of the Securities
         Act or the Exchange Act, against any losses, claims, damages or
         liabilities (joint or several) to which they may become subject under
         the Securities Act, the Exchange Act or any other federal or state
         law, rule or regulation insofar as such losses, claims, damages or
         liabilities (or actions in respect thereof) arise out of or are based
         upon any of the following statements, omissions or violations
         (collectively, a "Violation"): (i) any untrue statement or alleged
         untrue statement of a material fact contained in such registration
         statement, including any preliminary prospectus or final prospectus
         contained therein or any amendments or supplements thereto, (ii) the
         omission or alleged omission to state therein a material fact required
         to be stated therein, or necessary to make the statements therein not
         misleading in light of the circumstances in which they were made, or
         (iii) any violation or alleged violation


                                     - 10 -

         by the Company of the Securities Act, the Exchange Act, any state
         securities law or any rule or regulation promulgated under the
         Securities Act, the Exchange Act or any state securities law; and the
         Company will reimburse each such Holder, officer, director, partner,
         employee, legal counsel, underwriter or controlling Person for any
         legal or other expenses reasonably incurred by them in connection with
         investigating or defending any such loss, claim, damage, liability or
         action or enforcing these indemnification provisions, as such expenses
         are incurred; provided, however, that the indemnity agreement
         contained in this subsection 7.7(a) shall not apply to amounts paid in
         settlement of any such loss, claim, damage, liability or action if
         such settlement is effected without the consent of the Company, nor
         shall the Company be liable in any such case for any such loss, claim,
         damage, liability or action to the extent that it arises out of or is
         based upon a Violation which occurs in reliance upon and in conformity
         with written information shed expressly for use in connection with
         such registration by any such Holder.

                  (b) To the extent permitted by law, each selling Holder will
         indemnify and hold harmless the Company, each of its directors and
         officers, its legal counsel, each Person, if any, who controls the
         Company within the meaning of the Securities Act, and any other Holder
         selling securities in such registration statement or any of such other
         Holder's directors, officers, employees, legal counsel or any Person
         who controls such Holder, against any losses, claims, damages or
         liabilities (joint or several) to which the Company or any such
         director, officer, employee, legal counsel, or controlling Person, or
         other such Holder or director, officer, employee, legal counsel or
         controlling Person of such other Holder may become subject, under the
         Securities Act, the Exchange Act or other federal or state law,
         insofar as such losses, claims, damages or liabilities (or actions in
         respect thereto) arise out of or are based upon any Violation, in each
         case to the extent (and only to the extent) that such Violation occurs
         in reliance upon and in conformity with written information furnished
         by such Holder expressly for use in connection with such registration;
         and each such Holder will reimburse any legal or other expenses
         reasonably incurred by the Company or any such director, officer,
         employee, legal counsel, controlling Person, other Holder, or officer,
         director, employee, legal counsel, or controlling Person of such other
         Holder in connection with investigating or defending any such loss.
         claim, damage, liability, or action or enforcing these
         indemnifications provisions, as such expenses are incurred; provided,
         however, that the indemnity agreement contained in this subsection
         7.7(b) shall not apply to amounts paid in settlement of any such loss,
         claim, damage, liability or action if such settlement is effected
         without the consent of the indemnifying Holder.

                  (c) Promptly after receipt by an indemnified party under this
         Section 7.7 of notice of the commencement of any action (including any
         governmental action), such indemnified party will, if a claim in
         respect thereof is to be made against any indemnifying party under
         this Section 7.7, give to the indemnifying party a written notice of
         the commencement thereof and the indemnifying party shall have the
         right to participate in, and, to the extent the indemnifying party so
         desires, jointly with any other indemnifying party similarly noticed,
         to assume the defense thereof with counsel mutually satisfactory to
         the parties; provided,


                                     - 11 -

<PAGE>   12



         however, that an indemnified party shall have the right to retain its
         own counsel at its own expense if it so desires. Notwithstanding the
         foregoing, if the indemnified party and the indemnifying party have
         conflicting interests with respect to the action so that joint counsel
         for them would be inappropriate (as determined by counsel to the
         indemnified party and counsel to the indemnifying party), then the
         indemnifying party shall pay reasonable fees and expenses of one
         counsel to the indemnified party. Each indemnified party shall give
         reasonably prompt notice to each indemnifying party or parties of any
         action or proceeding commenced against it in respect of which
         indemnity may be sought hereunder, but the failure to deliver written
         notice to the indemnifying party within a reasonable time of the
         commencement of any such action, shall not relieve such indemnifying
         party of any liability to the indemnified party under this Section
         7.7, unless the indemnifying party is materially prejudiced by such
         failure to give notice.

                  (d) If the indemnification provided for in this Section 7.7
         is held by a court of competent jurisdiction to be unavailable to an
         indemnified party or insufficient to hold harmless an indemnified
         party under subsection (a), (b), or (c) above, then each indemnifying
         party shall contribute to the amount paid or payable by such
         indemnified party as a result of the losses, claims, damages or
         liabilities referred to in subsection (a), (b), or (c) above, in such
         proportion as is appropriate to reflect the relative fault of the
         indemnifying party on the one hand and of the indemnified party on the
         other in connection with the action, statement or omission that
         resulted in such claims, as well as other equitable considerations.
         The relative fault shall be determined with reference to, among other
         things, whether the untrue statement or alleged omission to state a
         material fact relates to information supplied by the indemnifying
         party or such indemnified party and the parties' relative intent,
         knowledge, access to information and opportunity to correct or prevent
         such statement or omission. Notwithstanding the foregoing provisions
         of this Section 7.7, a Holder of Registrable Securities shall not, as
         an indemnifying party, be required to contribute any amount in excess
         of (x) the amount by which the total price at which the Registrable
         Securities sold by such indemnifying party were offered to the public
         exceeds (y) the amount of any damages which such indemnifying party
         has otherwise been required to pay by reason of such action, untrue or
         alleged untrue statement or omission or alleged omission. The Company
         and each Holder of Registrable Securities agrees that it would not be
         just and equitable if contribution pursuant to this Section 7.7(d)
         were determined by pro rata allocation or by any other method of
         allocation which does not take account of the equitable considerations
         referred to above in this Section 7.7(d). The amount paid or payable
         by an indemnified party as a result of the losses, claims, damages or
         liabilities referred to above in this Section 7.7(d) shall be deemed
         to include any legal or other expenses reasonably incurred by such
         indemnified party in connection with investigation or defense of any
         such action or claim which is the subject of this subsection (d) or
         enforcement of these contribution provisions.

                  (e) The obligations of the Company and Holders under this
         Section 7.7 shall survive the completion of any offering of
         Registrable Securities in a registration statement under this Article
         7, and otherwise.

                  7.8. Reports Under Securities Exchange Act. With a view to
making available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration, the Company agrees to:

                  (a)  make and keep public information available, as those
         terms are understood and defined in SEC Rule 144, at all times;

                  (b)  file with the SEC in a timely manner all reports and
         other documents required of the Company under the Securities Act and
         the Exchange Act; and

                  (c)  furnish to any Holder, so long as the Holder owns any
         Registrable Securities, forthwith upon request (i) a written statement
         by the Company that it has complied with the reporting requirements of
         SEC Rule 144, the Securities Act and the Exchange Act (at any time
         after it has become subject to such reporting requirements), and (ii)
         a copy of the most recent annual or quarterly report of the Company
         and such other reports and documents so filed by the Company.

                  7.9. Form S-3 Registration. In case the Company shall receive
at any time after ninety (90) days from the Closing Date written request or
requests from a Holder that the Company effect a registration on Form S-3 and
any related qualification or compliance with respect to all or a part of the
Registrable Securities owned by such Holder or Holders, the Company will:

                  (a)  promptly give written notice of the proposed 
         registration, and any related qualification or compliance, to all
         other Holders; and

                  (b)  as soon as practicable, effect such registration and all
         such qualifications and compliances as may be so requested and as
         would permit or facilitate the sale and distribution of all such
         portion of such Holder's or Holders' Registrable Securities as are
         specified in such request, together with all or such portion of the
         Registrable Securities of any other Holder or Holders joining in such
         request as are specified in a written request made within thirty (30)
         days after the Company shall have given such notice pursuant to
         Section 12.1 hereof; provided, however, that the Company shall not be
         obligated to effect any such registration, qualification or compliance
         pursuant to this Section 7.9 (i) if Form S-3 is not available for such
         offering by the Holders; (ii) if the Holders, together with the
         holders of any other securities of the Company entitled to inclusion
         in such registration, propose to sell Registrable Securities and such
         other securities (if any) at an aggregate price to the public of less
         than Five Million Dollars (US $5,000,000); (iii) if the Company shall
         furnish to the Holders a certificate signed by the CEO stating that in
         the good faith judgment of the Board of Directors it would be
         seriously detrimental to the Company and its stockholders for such
         Form S-3 Registration to be effected at such time, in which event the
         Company shall have the right to defer the filing of the Form S-3
         Registration Statement for a period of not more than one hundred
         eighty (180) days after receipt of the request of the Holder or
         Holders


                                     - 13 -

<PAGE>   14



         under this Section 7.9; provided, however, that the Company shall not
         utilize this right more than once in any 12 month period; (iv) if the
         Company within the nine month period preceding the date of such
         request, already has effected one registration on Form S-3 for the
         Holders pursuant to this Section 7.9 or within the 48 month period
         preceding the date of such request already has effected five such
         registrations and other similar provisions granting rights to the
         registration on Form S-3; or (v) in any particular jurisdiction in
         which the Company would be required to qualify to do business or to
         execute a general consent to service of process in effecting such
         registration, qualification or compliance.

                  Subject to the foregoing, the Company shall file a
         registration statement covering the Registrable Securities and other
         securities so requested to be registered (including securities which
         the Company wishes to issue), as soon as practicable after receipt of
         the request or requests of the Holders. All expenses, other than
         underwriting discounts and commissions, incurred in connection with
         the registrations pursuant to this Section 7.9, including (without
         limitation) all other registration, filing, qualification, printer's
         and accounting fees shall be borne by the Company.

                  7.10. Assignment of Registration Rights. The rights to cause
the Company to register Registrable Securities pursuant to this Article 7 may
be assigned by a Holder to a transferee or assignee who has lawfully received
the shares in a private sale in accordance with all applicable laws and
regulations and with respect to Registrable Securities, the terms of this
Shareholders' Agreement; provided, however, in each case, the Company is,
within a reasonable period of time after such transfer, given written notice of
the name and address of such transferee or assignee and the securities with
respect to which such registration rights are being assigned; and provided,
further, that such assignment shall be effective only if (i) immediately
following such transfer the further disposition of any such securities by the
transferee or assignee is restricted under the Securities Act and (ii) the
transferee agrees to be bound by the terms of this Article 7.

                  7.11. Amendment of Registration Rights. Any provision of this
Article 7 may be amended and the observance thereof may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the holders of
at least seventy percent (70%) of the Registrable Securities. Any amendment or
waiver effected in accordance therewith shall be binding upon each holder of
any securities purchased under this Shareholders' Agreement at the time
outstanding (including securities into which such securities are convertible),
each future holder of all such securities, and the Company; provided, however,
that no such amendment or the waiver of the observance of any provisions of
this Article 7 that adversely affect the rights of Vulcan Ventures Incorporated
may occur without Vulcan Ventures Incorporated's consent.

                  7.12. Termination of Registration Rights. The Company's
obligations pursuant to this Article 7 shall terminate with respect to each
Holder upon the earlier to occur of (i) five (5) years after the Closing Date
or (ii) such time as such Holder may sell all of its Registrable Securities


                                     - 14 -

         11.      SPECIFIC PERFORMANCE.

         The Shareholders, the Company and Howard acknowledge and agree that
the recovery of money damages will not constitute an adequate remedy for breach
of the provisions of this Shareholders' Agreement. Accordingly, the parties

enforced against them and transferees of securities of the Company which are
subject to this Shareholders' Agreement (in addition to any other remedies
available for breach of this Shareholders' Agreement), and the parties (for
themselves and, in the case of the Shareholders, transferees of their
securities of the Company), hereby waive the defense in any equitable
proceeding that there is an adequate remedy at law for any such breach.

                       HAYES MICROCOMPUTER PRODUCTS, INC.
                          AGREEMENT AND PLAN OF MERGER



         THIS AGREEMENT AND PLAN OF MERGER (the "Agreement") is made as of the
12th day of April, 1996, by and among HAYES MICROCOMPUTER PRODUCTS, INC., a
Georgia corporation (the "Company"), DENNIS C. HAYES, a Georgia resident
("Dennis Hayes"), each of the individuals or entities listed on Schedule 1
hereto and identified thereon as the "Investors" (which are referred to herein
from time to time individually as an "Investor" or collectively as the
"Investors") and the direct or indirect subsidiary of one of the Investors,
formed or to be formed, as identified on Schedule 1 hereto ("Investor Sub").


                                   BACKGROUND


         A. On November 15, 1994, the Company filed a petition in the United
States Bankruptcy Court for the Northern District of Georgia (the "Bankruptcy
Court") seeking protection from its creditors and a reorganization under Chapter
11 of Title 11 of the United States Code (the "Bankruptcy Code"), in the case
entitled In re Hayes Microcomputer Products, Inc., a/k/a Practical Peripherals,
Inc., Bankr. Case No. A94-75900-HR (the "Bankruptcy Case"). On May 15, 1995, the
Company filed with the Bankruptcy Court its Plan of Reorganization (as amended
on July 6, July 10, July 20, August 21, November 1, November 16 and December 8,
1995, January 8, 1996, and February 9, 1996, and pursuant to the Order (as
defined below), and as it may otherwise be amended in accordance with the terms
of this Agreement, the "Plan"). The Company is the Debtor-in-Possession in the
Bankruptcy Case, no trustee having been appointed.

         B. The Company has obtained an Order of the Bankruptcy Court dated
March 8, 1996, pursuant to Section 1129 of the Bankruptcy Code and intends to
seek an Order in Aid of Confirmation (the "Order in Aid of Confirmation") (i)
confirming the Plan, including without limitation the amendment to the Company's
Articles of Incorporation contemplated by Section 1.1(d) and the merger of the
Company (as described in Section 1.1) including without limitation the issuance
of the Preferred Shares (as defined in Section 1.1) and the Warrant (as defined
in Section 1.3) to the Investors as set forth herein; (ii) approving any
required amendments to the Disclosure Statement with Regard to Debtor's Second
Amended and Restated Plan of Reorganization dated July 20, 1995; and (iii)
approving this Agreement and each of the agreements and certificates
contemplated by this Agreement, as such agreements may be amended from time to
time, such Orders as approved and entered by the Bankruptcy Court being
hereinafter referred to collectively as the "Order." The date upon which the
Plan becomes effective is hereinafter referred to as the "Effective Date."

         C. The parties desire to consummate a merger that will constitute a
reorganization pursuant to Section 368(a)(1)(A) of the Internal Revenue Code of
1986, as amended.

         D. Pursuant to that certain Notice of Election of Alternative Treatment
under the Debtor's Second Amended and Restated Plan of Reorganization, as
Modified and Amended, filed on March 13, 1996 (the "Election"), Melita Easters
Hayes has elected under the Plan to have the shares of Common Stock owned by her
redeemed by the Company for a total consideration of Eleven Million U.S. Dollars
(US $11,000,000) payable at such time and in the manner provided by the Plan,
which redemption shall occur simultaneously with the Closing (as defined in
Section 1.4).


                                    AGREEMENT

         In consideration of the mutual promises, covenants and conditions
hereinafter set forth, the parties hereby agree as follows:

         1. Plan of Merger.

            1.1 Terms and Conditions of Merger.

                  (a) Merger. Prior to the date hereof, Rinzai Limited
("Rinzai") has formed or will form Financial Sub, Inc. ("Financial Sub"), which
is a directly or indirectly owned subsidiary under the Georgia Business
Corporation Code (the "Georgia Code") for the purpose of accomplishing the
merger described herein, which is a party hereto. Upon the terms and subject to
the conditions set forth herein and in accordance with the Georgia Code, at the
Effective Time, Financial Sub shall be merged with and into the Company (the
"Merger"), and the separate existence of Financial Sub shall cease. The Company

authorization of, or registration, qualification, designation, declaration or
filing with, any foreign, United States federal, state, local or provincial
governmental authority on the part of the Company or any Subsidiary is required
to be obtained in connection with:

                  (a) the Company's valid execution, delivery, or performance of
this Agreement, the Warrant, the Cap Call Notes, the Investors Shareholders'
Agreement, the Voting Trust Agreement or the Employment Agreement; and

                  (b) the offer, sale, or issuance by the Company of the
Securities hereunder and the Cap Call Notes under the Investors Shareholders'
Agreement or (assuming the exemption provided by Section 3(a)(9) of the

except for the Order in Aid of Confirmation by the Bankruptcy Court, and as
required pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976
(the "HSR Act"), and except for any notices of sale required to be filed with
the Securities and Exchange Commission ("SEC") under Regulation D of the
Securities Act, or such post-closing filings as may be required under applicable
state securities laws, which will be timely filed within the applicable periods
therefor.

              2.7 Litigation. There is no action, suit, proceeding, claim,
arbitration, audit or investigation (an "Action") pending or to the best
knowledge of the Company currently threatened against the Company or any
Subsidiary, its properties or assets or, to the best knowledge of the Company
against any officer, director, employee, consultant, independent contractor,
agency employee or other agent of the Company or any Subsidiary in connection
with such individual's relationship with, or actions taken on behalf of, the
Company or any Subsidiary which questions the validity of this Agreement or the
right of the Company to enter into this Agreement, or to consummate the
transactions contemplated hereby, or which might result, either individually or
in the aggregate, in any material adverse change in the assets, condition, or
prospects of the Company and its Subsidiaries taken as a whole, financial or
otherwise, or any change in the current equity ownership of the Company or any
Subsidiary. To the best knowledge of the Company, there is no factual basis for
any such Action that might result, individually or in the aggregate, in any
material adverse change in the assets, condition or prospects of the Company or
any Subsidiary, financial or otherwise. By way of example but

                                     - 12 -

<PAGE>   13



not by way of limitation, there are no Actions pending or, to the best knowledge
of the Company, threatened (or any basis therefor known to the Company) relating
to the prior employment of any officer, director, employee, consultant,
independent contractor, agency employee or other agent of the Company or any
Subsidiary, their use in connection with the Company's business of any
information, technology or techniques allegedly proprietary to any of their
former employers, clients or other parties, or their obligations under any
agreements with prior employers, clients or other parties which would result in
any material adverse change in the assets, condition, or prospects of the
Company and its Subsidiaries taken as whole, financial or otherwise. Neither the
Company nor any Subsidiary is a party or subject to the provisions of any
settlement agreement, order, writ, injunction, judgment or decree of any court
or government agency or instrumentality, other than orders of the Bankruptcy
Court in the Bankruptcy Case, true and complete copies of which orders have been
furnished to the Investors. There is no Action by the Company nor any Subsidiary
currently pending or which the Company or any Subsidiary intends to initiate.

              2.8 Patents and Trademarks. The Company's and its Subsidiaries' 
businesses as now conducted do not conflict with or infringe upon anyone's
patents, copyrights, trademarks, service marks, mask works, trade secrets, or
other proprietary rights in a manner which would have a material adverse effect
on the assets, condition or prospects of the Company or any Subsidiary,
financial or otherwise. The Company either directly or through its Subsidiaries
owns, or has the right to use, all patents, trademarks, service marks,
copyrights, mask works, trade secrets or other proprietary rights necessary for
the conduct of its business as it is presently conducted without infringing on
any patents, trademarks, service marks, copyrights, mask works, trade secrets or
other proprietary rights of others. Neither the Company nor any Subsidiary has
received any communications alleging that the Company or any Subsidiary (or any
of their respective employees or consultants) has violated or infringed or, by
conducting its business as proposed, would violate or infringe, any patents,
trademarks, service marks, copyrights, mask works, trade secrets or other
proprietary rights of any other person or entity. A complete list of all the
Company's patents, trademarks, service marks, copyrights, and mask works,
including applications for the foregoing, is attached as Annex A to the Schedule
of Exceptions. To the best knowledge of the Company, no third party has any
ownership right, title, interest, claim in or lien on any of the Company's
patents, trademarks, service marks, copyrights, mask works, trade secrets or
other proprietary rights and the Company has taken, and in the future the
Company intends to use its best efforts to take, all steps reasonably necessary
to preserve its legal rights in the same. Neither the Company nor any Subsidiary
is obligated to pay any royalties or other payments to third parties with
respect to the license or use of any patents, trademarks, service marks,
copyrights, mask works, trade secrets or other proprietary rights.

              2.9 Compliance with Law. The execution and delivery of this
Agreement, the Employment Agreement, the Investors Shareholders' Agreement, the
Voting Trust Agreement and the Warrant by the Company do not, and the
consummation of the Merger and the issuance of the Cap Call Notes, the Common
Stock, the Preferred Shares and the other transactions contemplated hereby and
thereby will not, subject to the entry of the Order in Aid of Confirmation by
the Bankruptcy Court, violate or constitute an occurrence of default under any
provisions of the articles of incorporation or bylaws of the Company or any of
its Subsidiaries

                                     - 13 -

<PAGE>   14



or any judgment, order, writ or decree to which the Company, or any of its
Subsidiaries is a party or by which any of the foregoing is bound or its assets
are affected or violate any foreign, domestic, federal, state or local statute,
ordinance, rule or regulation applicable to the Company or any of its
Subsidiaries or their respective businesses and assets. The Company and each
Subsidiary is presently conducting its business so as to comply with all
applicable foreign, domestic, federal, state and local statutes, ordinances,
rules and regulations of any governmental authority, the violation of which
would have a material adverse effect on the assets, condition or prospects of
the Company or any Subsidiary, financial or otherwise. The Company and each
Subsidiary is presently conducting its business so as to comply in all respects
with all judgments, orders, writs and decrees to which it is a party or its
assets or businesses are affected.

             2.10 Agreements; Action.

                  (a) There are no agreements, understandings, instruments or
contracts to which the Company or any Subsidiary is a party or by which it is
bound which involve (i) the leasing or subleasing of any real property or
material item of personal property (which shall exclude leases of personal
property having payment obligations of less than $100,000 per year), or (ii) the
employment of any individuals by the Company or any of its Subsidiaries, or
(iii) license of any patent, trademark, service mark, copyright, mask work,
trade secret or other proprietary right, or (iv) a joint venture or partnership,
acquisition or disposition of a material asset, or the purchase or sale of
securities, or (v) the settlement of any Action by or against the Company or any
Subsidiary (collectively, with the agreements and arrangements described in
items (x), (y) and (z) of the following sentence of this subsection, the
"Material Agreements"). The Schedule of Exceptions contains a true, correct and
complete list of (x) the top twenty (20) reseller agreements and arrangements of
the Company or any of its Subsidiaries, determined on the basis of expected
revenues during the current fiscal year; (y) the top twenty (20) agreements and
arrangements of the Company or any of its Subsidiaries, determined on the basis
of expected revenues during the current fiscal year; and (z) the top twenty (20)
agreements and arrangements of the Company or any of its Subsidiaries determined
on the basis of expected monetary obligations during the current fiscal year.
Neither the Company nor any Subsidiary has breached any Material Agreement in
any material respect. Neither the Company nor any Subsidiary has, and to the
Company's best knowledge no other party thereto has, breached any provision of
or is in default under any agreement or arrangement to which the Company or any
Subsidiary is a party, which breach or default would have a material adverse
effect on the assets, condition or prospects of the Company or any Subsidiary,
financial or otherwise. Dennis Hayes has not breached, nor does the Company have
any knowledge of any claim or threat that Dennis Hayes has breached, the 1988
Shareholder Agreement. Each Material Agreement is in full force and effect and,
to the best knowledge of the Company, no other party to such Material Agreement
is or threatens to be in default thereunder, and there is no basis for
termination thereunder. Each of the Material Agreements is enforceable by and
against the Company or its Subsidiaries in accordance with its terms, except as
affected by (i) the Bankruptcy Code or the Plan, or (ii) equitable principles or
the exercise of judicial discretion. The execution and delivery of this
Agreement, the Employment Agreement, the Warrant, the Voting Trust Agreement,
the Cap Call Notes and the Investors Shareholders' Agreement by the Company do
not, and the consummation of the Merger and the other transactions contemplated
hereby and thereby will not, violate or constitute an occurrence of default
under (A) any Material Agreement

                                     - 14 -

<PAGE>   15



or (B) any agreement, document or instrument to which the Company or any of its
Subsidiaries is a party or any of its assets or business is bound or affected
which violation or default would have a material adverse effect on the assets,
condition or prospects of the Company or any of its Subsidiaries, financial or
otherwise.

                  (b) The Company has not since September 30, 1995 (i) declared
or paid any dividends, or authorized or made any distribution upon or with
respect to any class or series of its capital stock, or agreed to do any of the
foregoing, (ii) incurred any indebtedness for money borrowed or incurred any
other liabilities individually in excess of US $50,000 or in excess of US
$250,000 in the aggregate, other than obligations or liabilities of the Company
entered into (x) in the ordinary course of business and consistent with prior
practice or (y) in connection with the Bankruptcy Case of less than Six Million
U.S. Dollars (US $6,000,000) in the aggregate, (iii) made any loans or advances
to any person, or (iv) sold, exchanged or otherwise disposed of any of its
material assets or rights.

                  (c) The Company (i) is not a party to any contract with any
agency or instrumentality of the U.S. government (a "Government Agency") which
has been classified as to confidentiality by such Government Agency; (ii) does
not manufacture or sell any products which have been designed to transmit
encrypted voice, video or data traffic; (iii) does not manufacture or sell any
products or items which are controlled pursuant to the International Traffic in
Arms Regulations; (iv) does not conduct research or development activities for
any Government Agency; and (v) does not sell any products to any Government
Agency for which there is no readily available substitute which would perform
substantially the same function.

             2.11 Registration Rights. Except for the registration rights
under the 1988 Shareholder Agreement (which rights will be terminated as of the
Redemption) and except as provided in the Investors Shareholders' Agreement, the
Company has not granted or agreed to grant any registration rights, including
piggy-back rights, to any person or entity.

             2.12 Title to Property and Assets. Included in the Schedule of
Exceptions is a true, correct and complete list and brief description of all
real property and a list of all material items of personal property owned or
leased by the Company and each of its Subsidiaries. The Company and its
Subsidiaries own their property and assets free and clear of all mortgages,
liens, claims, loans and encumbrances, except such encumbrances and liens which
arise in the ordinary course of business (excluding liens for borrowed money, or
that may arise by reason of violations of law or breach of contract) and do not
materially impair the Company's or its Subsidiaries' ownership or use of such
property or assets. With respect to the property and assets it leases, the
Company and each of its Subsidiaries are in compliance with such leases and, to
the best knowledge of the Company, holds a valid leasehold interest free of any
liens, claims or encumbrances, which liens, claims or encumbrances would be
materially adverse to the Company or such Subsidiary.

             2.13 Voting Arrangements. The Company is not a party to, nor
to the best knowledge of the Company, are there any outstanding shareholder
agreements, voting trusts, proxies or other arrangements or understandings among
the shareholders of the Company relating to the voting of their respective
shares.

Investor its audited financial statements (balance sheet and profit and loss
statement) at and for the fiscal year ended September 30, 1994, and its
unaudited financial statements (balance sheet, profit and loss statement) at and
for the year ended September 30, 1995 (the "Financial Statements"). The
Financial Statements are complete and correct in all material respects and have
been prepared in accordance with generally accepted accounting principles
consistently applied throughout the periods involved and have been prepared on a
consistent basis throughout the periods indicated. The Company has also
delivered to the Investors true and complete copies of all reports prepared by
Arthur Andersen & Company and Deloitte & Touche with respect to the Company. The
Financial Statements fairly present the financial condition and operating
results of the Company and its Subsidiaries on a consolidated basis as of the
dates, and for the periods, indicated therein.

             The Company and its Subsidiaries have incurred no liabilities or
obligations since September 30, 1995, whether absolute, accrued, contingent or
otherwise, except for (a) the liabilities and obligations of the Company
disclosed or provided for in the Plan, to the extent and in the amounts so
disclosed or provided for, and (b) liabilities incurred or accrued in the
regular and ordinary course of business which will not, either individually or
in the aggregate, have a material adverse effect on the assets, condition or
prospects of the Company or its Subsidiaries, financial or otherwise.

             2.15 Changes. Since September 30, 1995, there has been no material
adverse change in the assets, liabilities (contingent or otherwise), condition,

Company, no officer, director, employee or consultant of the Company or any
Subsidiary in connection with such employee's employment with the Company or any
Subsidiary, has violated the terms of any agreement with a previous employer. To
the best knowledge of the Company, none of the officers, directors, employees or
consultants of the Company or any Subsidiary are obligated under any contract
(including licenses, covenants or commitments of any nature) or other agreement,
or subject to any judgment, decree or order of any court or administrative
agency, that would conflict with their obligation to use their best efforts to
promote the interests of the Company and its Subsidiaries or that would conflict
with the Company's business as conducted. It is currently not necessary nor will
it be necessary for the Company or any of its Subsidiaries to utilize, nor will
the Company or any of its Subsidiaries utilize, any inventions of any of its
directors, officers, employees or consultants (or people it currently intends to
hire) made or owned (by the directors, officers, employees or consultants or
their former employees) prior to their employment with or engagement by the
Company or any of its Subsidiaries in violation of any limitations or
restrictions to which any such director, officer, employee or consultant is a
party. To the best knowledge of the Company, none of the directors, officers,
employees or consultants (including without limitation former directors,
officers, employees and consultants) of the Company or any of its Subsidiaries
have taken, removed or made copies of any proprietary documentation, manuals,
products, materials, or any other tangible item from his or her previous

such previous employer.

             2.18 Permits. The Company and its Subsidiaries have all franchises,
permits, licenses, orders of the Bankruptcy Court and any similar authority
necessary for the conduct of its business as now being conducted by it, the lack
of which could materially and adversely affect the business, properties,
prospects, or financial condition of the Company or any of its Subsidiaries and
believes it can obtain, without undue burden or expense, any similar authority
for the conduct of its business as currently planned to be conducted. Neither
the Company nor any of its Subsidiaries is in default in any material respect
under any of such franchises, permits, licenses, or other similar authority.
Neither the execution nor delivery of this Agreement, the Employment Agreement,
the Warrant, the Voting Trust Agreement, the Cap Call Notes or the Investors
Shareholders' Agreement, nor the consummation of the transactions contemplated
hereby and thereby will result in the termination of any material franchise,
permit, license or right held by the Company or any Subsidiary, and all such
franchises, permits, licenses and rights will remain vested in and inure to the
benefit of the Company and the Subsidiaries after the consummation of the
transactions contemplated by this Agreement.

respects.

             2.21 Tax. As used in this Agreement, "taxes" or "tax liability"
means all taxes (including but not limited to income taxes, excise taxes, sales

any other taxes), including applicable interest additions to tax and penalties.

                  (a) Each of the Company and its Subsidiaries has filed all
required tax returns, and has paid all taxes owed by any of the Company and its
Subsidiaries (whether or not shown on any tax return) with respect to any period
ending on or before the date of Closing or any period on or before the last day
of the taxable year of the Company's consolidated group in which the Closing
date occurs (determined with respect to such year by closing the books of the
Company and its Subsidiaries as of the end of the Closing date). Such returns
are correct and complete in all material respects.

                  (b) Each of the Company and its Subsidiaries has withheld and
paid all taxes required to have been withheld and paid in connection with
amounts paid or owing to any employee, independent contractor, creditor,
shareholder or other third party.

for taxes (i) as a transferee or successor, or (ii) imposed by contract which
would not be otherwise paid by the Company or such Subsidiary.

             There are no unpaid foreign, federal, state or local taxes assessed
or asserted in writing in respect of any tax returns filed by the Company or any
of its Subsidiaries or claimed in writing to be due by the appropriate taxing
authority, except those, if any, currently being contested in good faith which
are disclosed on the Schedule of Exceptions. Neither the Company nor any of its
Subsidiaries is being audited or has ever been audited by the Internal Revenue
Service (the "IRS") or any other taxing authority. No request by the Company or
any of its Subsidiaries for ruling or determination letters relating to foreign,
federal, state or local taxes is pending with any taxing authority. Neither the
Company nor any of its Subsidiaries has agreed to or is required to make any
adjustment pursuant to Section 481(a) of the Code, by reason of a change in
accounting method initiated by it or required by law, and neither the Company
nor Dennis Hayes has any knowledge that the IRS has proposed or purported to
require any such adjustment or change in accounting method.

incident of or relating to Hazardous Materials (as hereinafter defined) that (i)

"run-out" provisions. All terminated compensation and benefit plans, programs,
arrangements and agreements of the Company or any of its Subsidiaries were
terminated in accordance with the written provisions of the plan, program,
arrangement or agreement and of applicable provisions of the Code and ERISA. Any
employee pension benefit plan which was qualified under Code Section 401(a)
retained its qualified plan status at the time of termination of the plan.

that plan holds or held securities of the Company or any Subsidiary as an
investment of the plan, the Employee Stock Plan, its sponsors, fiduciaries and
trustee have complied in all material respects with all requirements of the
federal or state securities laws, ERISA and the Code which apply to the
purchase, holding or sale of such securities by an employee pension benefit plan
which is intended to be a qualified plan under Section 401(a) of the Code. Such

Disclosure Memorandum and the information contained therein shall not modify any
representation and warranty of the Company contained in this Agreement.

legally binding agreement or undertaking with or made legally binding promises
to any Investor, as an inducement for such Investor to enter into this Agreement

Investor in the future on any basis or (ii) to make any investment, directly or
indirectly, in any entity or facility.

the Company and each Subsidiary shall operate their respective businesses only
in the ordinary course consistent with prior practice and not to:

                      (i)   take any action of the nature referred to in

                  (b) The Company shall preserve the business organization of
the Company and each Subsidiary intact and shall use its best efforts to keep
available to the Company the services of the present officers and employees of
the Company and each Subsidiary and to preserve for the Company the goodwill of
the Company's and each Subsidiary's suppliers, customers, distributors, sales
representatives and others having business relations with the Company or any
Subsidiary.

                  (c) The Company and each Subsidiary shall maintain in force
the insurance policies referred to in Section 2.23 or insurance policies
providing the same or substantially similar coverage; provided, however, that
the Company will notify the Investors prior to the expiration of any of such

                      (ii)  amended (except as expressly required by law) in any
manner which would directly or indirectly increase the benefits accrued, or
which may be accrued, by any participant thereunder; or

                      (iii) amended in any manner which would materially
increase the cost to the Company or any Subsidiary of maintaining such plan,
fund, or arrangement.

             6.2 Employment Agreement. At the Closing, Dennis Hayes and the
Company shall enter into an Employment Agreement in the form attached hereto as
Exhibit "F" (the "Employment Agreement").

             6.3 Consents. The Company and Dennis Hayes agree to take all
actions and effect all filings necessary to obtain all licenses, consents,
approvals and authorizations of all third parties and governmental bodies
necessary for it to consummate the Merger and the other transactions
contemplated by this Agreement.

             6.4 Chief Executive and Chief Financial Officers. During the period
prior to the Closing, the Company agrees not to appoint, or enter into any
agreement or arrangement to appoint, a new Chief Executive Officer or Chief
Financial Officer without first obtaining the prior written consent of the
Investors purchasing a majority of the Preferred Shares, which consent may be
withheld by any such party in exercise of its sole and absolute discretion.

             6.5 Examination of Records. Subject to any applicable court orders,
during the period prior to the Closing, the Company shall allow the Investors,
their respective counsel and other representatives reasonable access during
normal business hours to all books, records, files, documents, assets,
properties, contracts and agreements of the Company and its Subsidiaries and
shall furnish Investors and their respective counsel and representatives with
all available information concerning the affairs of the Company and its
Subsidiaries which is reasonably requested or as necessary to allow the Investor
to make (i) the representation and warranty contained in Section 3.5 hereof, or
(ii) the determination that the condition set forth in Section 4.9 has been
satisfied.

             6.6 Delivery of Interim Financial Statements. During the period
prior to the Closing, the Company shall promptly deliver to each Investor all
regularly prepared unaudited financial statements of the Company, in format
historically utilized internally, as soon as available.

             6.7 Notification of Certain Matters. Promptly after receipt of
notice thereof, each of the Company, Dennis Hayes, and the Investors shall
advise the other parties hereto of (i) the occurrence or failure to occur of any
event, the occurrence or failure of which is reasonably believed by such party
to cause any representation or warranty of such party contained in this
Agreement to be untrue or inaccurate in any material respect any time from the
date hereof through the Closing Date; and (ii) any material failure of such
party to comply with or satisfy any covenant or condition to be complied with or
satisfied by him or it hereunder prior to the Closing; and such party shall use
his or its commercially reasonably efforts to remedy the same.

             6.8  Debt Financing. The Company agrees, and Dennis Hayes as

             7.   Indemnification.

             7.1 Indemnification by the Company. The Company hereby agrees to
defend, indemnify and hold harmless each Investor and their respective
successors, assigns and affiliates (collectively, the "Investor Indemnitees")
from and against any and all losses (including, without limitation, any
diminution in value of the Investor's investment in the Company, based on the
valuation of the Company as of the date of Closing of US $71,400,000),
deficiencies, liabilities, damages, assessments, judgments, costs and expenses,
including attorneys' fees (both those incurred in connection with the defense or
prosecution of the indemnifiable claim and those incurred in connection with the
enforcement of this provision) (collectively, "Investor Losses"), caused by,
resulting from or arising out of:

                  (a) (i) breaches of any representation or warranty on the part
of the Company herein or in the Schedule of Exceptions or any Schedule or
Exhibit hereto or in any other written statement, certificate or other
instrument delivered by it pursuant hereto; and (ii) failures by the Company to
perform or otherwise fulfill any of its undertakings or other agreements
(including, without limitation, the Investors Shareholders' Agreement, the Cap
Call Notes, the Voting Trust Agreement and the Warrant) or obligations
hereunder;

                  (b) any and all actions, suits, proceeding, claims or demands
arising out of, or otherwise relating to, the Employee Stock Plan in respect of
the period prior to the ninetieth (90th) day following the date of Closing;

                  (c) any and all actions, suits, proceedings, claims or demands
arising out of, or otherwise relating to, brokers or finders fees sought by The

                  (d) any and all actions, suits, proceedings, claims or demands
relating to Gary J. Franza, John C. Stuckey and Mikail Drabkin (the "Employee
Actions"); and

                  (e) any and all actions, suits, proceedings, claims or demands
incident to any of the foregoing or such indemnification;

provided, however, that if any claim, liability, demand, assessment, action,
suit or proceeding shall be asserted by a third party naming an Investor
Indemnitee as a party to an action or otherwise making a claim or seeking
recovery from an Investor Indemnitee in respect of which an Investor Indemnitee
proposes to demand indemnification (a "Third Party Investor Indemnified

                                     - 33 -

<PAGE>   34



Claim") from the Company, such Investor Indemnitee shall notify the Company,
provided further, however, that the failure to so notify the Company shall not
reduce or affect the obligations of the Company with respect thereto except to
the extent that the Company is materially prejudiced thereby. Subject to Section
7.6 of this Agreement and to rights of or duties to any insurer or other third
person having liability therefor, the Company shall have the right promptly upon
receipt of such notice to assume the control and defense of, and to compromise
or settle, any such Third Party Investor Indemnified Claims, unless the Investor
Indemnitee notifies the Company that such Investor Indemnitee has determined, in
the exercise of its reasonable discretion, that a conflict of interest makes
separate representation by such Investor Indemnitee's own counsel advisable. If
the Investor Indemnitee gives the foregoing notice, it will have the right,
subject to Section 7.6 hereof, to assume the control and defense of and to
compromise and settle any such Third Party Investor Indemnified Claim. The
Company shall be responsible for the costs and expenses of such defense.

             7.2 Indemnification by Dennis Hayes. Dennis Hayes hereby agrees to
defend, indemnify and hold harmless each Investor Indemnitee from and against
any and all Investor Losses, caused by, resulting from or arising out of:

                  (a) (i) breaches of any representation or warranty on the part
of Dennis Hayes herein or in the Schedule of Exceptions or any Schedule or
Exhibit hereto or in any other written statement, certificate or other
instrument delivered by him pursuant hereto; and (ii) failures by Dennis Hayes
to perform or otherwise fulfill any of his undertakings or other agreements
(including, without limitation, the Investors Shareholders' Agreement, the Cap
Call Notes, the Voting Trust Agreement and the Employment Agreement) or
obligations hereunder; or

                  (b) any and all actions, suits, proceedings, claims or
demands, incident to any of the foregoing or such indemnification;

provided, however, that if any Third Party Investor Indemnified Claim shall be
asserted in respect of which an Investor Indemnitee proposes to demand
indemnification from Dennis Hayes, such Investor Indemnitee shall notify Dennis
Hayes of such Third Party Investor Indemnified Claim, provided further, however,
that the failure to so notify Dennis Hayes shall not reduce or affect the
obligations of Dennis Hayes with respect thereto except to the extent that
Dennis Hayes is materially prejudiced thereby. Subject to Section 7.6 of this
Agreement and to rights of or duties to any insurer or other third person having
liability therefor, Dennis Hayes shall have the right promptly upon receipt of
such notice to assume the control and defense of, and to compromise or settle,
any such Third Party Investor Indemnified Claims, unless the Investor Indemnitee
notifies Dennis Hayes that such Investor Indemnitee has determined, in the
exercise of its reasonable discretion, that a conflict of interest makes
separate representation by such Investor Indemnitee's own counsel advisable. If
the Investor Indemnitee gives the foregoing notice, it will have the right,
subject to Section 7.6 hereof, to assume the control and defense of and to
compromise and settle any such Third Party Investor Indemnified Claim. Dennis
Hayes shall be responsible for the costs and expenses of such defense on a pro
rata basis.

             7.3 Indemnification by the Investors. Each Investor hereby
respectively and severally, and not jointly, agrees to defend, indemnify and
hold harmless the Company and its respective successors, assigns and affiliates
and Dennis Hayes (collectively, the "Company Indemnitees") from and against any
and all losses, deficiencies, liabilities, damages, assessments, judgments,
costs and expenses, including attorneys' fees (both those incurred in connection
with the defense or prosecution of the indemnifiable claim and those incurred in
connection with the enforcement of this provision) (collectively, "Company
Losses"), caused by, resulting from or arising out of:

                  (a) (i) breaches of any representation or warranty on the part
of such Investor herein or in any Schedule or Exhibit hereto or in any other
written statement, certificate or other instrument delivered by such Investor
pursuant hereto; and (ii) failures by such Investor to perform or otherwise
fulfill any of its undertakings or other agreements (including, without
limitation, the Investors Shareholders' Agreement and the Cap Call Notes) or
obligations hereunder; and

                  (b) any and all actions, suits, proceedings, claims or demands
incident to any of the foregoing or such indemnification;

provided, however, that if any claim, liability, demand, assessment, action,
suit or proceeding shall be asserted by a third party naming a Company
Indemnitee as a party to an action or otherwise making a claim or seeking
recovery from a Company Indemnitee in respect of which a Company Indemnitee
proposes to demand indemnification from an Investor (a "Third Party Company
Indemnified Claim"), such Company Indemnitee shall notify the Investor thereof,
provided further, however, that the failure to so notify the Investor shall not
reduce or affect the obligations of such Investor with respect thereto except to
the extent that such Investor is materially prejudiced thereby. Subject to
Section 7.6 of this Agreement and to rights of or duties to any insurer or other
third person having liability therefor, such Investor shall have the right
promptly upon receipt of such notice to assume the control and defense of, and
to compromise or settle, any such Third Party Company Indemnified Claims, unless
the Company Indemnitee notifies such Investor that such Company Indemnitee has
determined, in the exercise of its reasonable discretion, that a conflict of
interest makes separate representation by such Company Indemnitee's own counsel
advisable. If the Company Indemnitee gives the foregoing notice, it shall have
the right, subject to Section 7.6 hereof, to assume the control and defense of
and to compromise and settle any such Third Party Company Indemnified Claim. The
indemnifying Investor shall be responsible for the costs and expense of such
defense.

             7.4 Certain Limitations.

                  (a) The obligations of the Company to indemnify Investor
Indemnitees under Section 7.1(a)(i) of this Article shall accrue only if the
aggregate Investor Losses for all matters indemnifiable under this Article 7
exceed Five Hundred Thousand Dollars (US $500,000), and then the Company shall
be liable for all such Investor Losses, subject to the maximum amount described
below; provided, however, that there shall be no such limitation on Investor
Losses arising from a breach of any of the representations or warranties in
Sections 2.2, 2.4, 2.5 and 2.19 hereof. The obligations of the Company to
indemnify the Investors under this Article 7 shall not exceed the aggregate of
Seventeen Million Five Hundred Thousand U.S.

                                     - 35 -

<PAGE>   36



Dollars (US $17,500,000), plus fifty percent (50%) of the amount of all advances
made by the Investors which are converted into capital stock of the Surviving
Corporation as contemplated by the Investors Shareholders' Agreement, plus fifty
percent (50%) of the aggregate of all amounts paid by Rinzai upon any exercise
of the Warrant; provided, however, that there shall be no such limitation with
respect to a breach of Sections 2.2, 2.4, 2.5 and 2.19 hereof. Notwithstanding
the foregoing provisions of this subsection 7.5(a), there shall be no limitation
on the obligations of the Company to indemnify Investor Indemnitees against
Investor Losses arising from Third Party Investor Indemnified Claims.

                  (b) The obligations of Dennis Hayes to indemnify Investor
Indemnitees under Section 7.2(a)(i) of this Article 7 (other than in respect of
Third Party Investor Indemnified Claims) shall accrue only if the aggregate
Investor Losses for all matters indemnifiable under this Article 7 exceed Two
Million Five Hundred Thousand Dollars (US $2,500,000) (the "Minimum Amount") and
then Dennis Hayes shall be liable for all such Investor Losses, subject to the
maximum amount described below; provided, however, that there shall be no such
requirement to exceed the Minimum Amount on Investor Losses arising from a
breach of any of the representations or warranties in Sections 2B.1, 2B.2, 2B.4,
2B.5 and 2B.6 (to the extent such breach relates to Section 2.2, 2.4, 2.5 or
2.19). The obligations of Dennis Hayes to make a payment to an Investor
Indemnitee pursuant to Section 7.2 of this Article 7 in respect of any Third
Party Investor Indemnified Claims which relate to a breach of Section 2B.6 shall
arise only when such Investor Indemnitee has diligently sought payment from the
Company and determined in good faith that the Company has insufficient assets to
satisfy such Third Party Investor Indemnified Claim; provided, however, that no
such Investor Indemnitee shall be required to seek to recover payment from the
Company in the event that the Company is subject to Chapter 7 or Chapter 11 of
the Bankruptcy Code. The obligations of Dennis Hayes to indemnify the Investors
under this Article 7 shall not exceed the aggregate of Three Million Five
Hundred Thousand Dollars (US $3,500,000).

                  (c) The obligations of each Investor to indemnify the Company
Indemnitees under Section 7.3(a)(i) of this Article 7 shall accrue only if the
aggregate of its respective Company Losses of the Company Indemnitees for all
matters indemnifiable under this Article 7 exceed Five Hundred Thousand Dollars
(US $500,000) and then such Investor shall be liable for all such Company
Losses, subject to the maximum amount described below; provided, however, that
there shall be no such limitation on Company Losses arising from a breach of any
of its representations and warranties in Sections 3.1, 3.4, 3.6, 3.7, 3.8 and
3.9 hereof. The obligations of each Investor to indemnify the Company
Indemnitees under this Article 7 shall not exceed one-half (1/2) of the purchase
price of the Preferred Shares purchased by it pursuant to Section 1.3(a), or, in
the case of Rinzai only, one-half (1/2) of its capital contribution to its
Investor Sub pursuant to Section 1.1(e).

             7.5  Waiver. Dennis Hayes hereby irrevocably waives any right
against the Company or the Surviving Corporation of subrogation, contribution,
indemnity or reimbursement to which he may be entitled in any capacity in
respect of his payment of Investor Losses pursuant to this Article 7.

             7.6  Defense of Certain Claims. In any Third Party Investor
Indemnified Claims or any Third Party Company Indemnified Claims defended by the
Company, Dennis Hayes or an Investor pursuant to this Agreement (i) the party
not controlling the defense of such claim shall have the right to be represented
by counsel and accountants, at such person's own

                                     - 36 -

<PAGE>   37



expense, (ii) the party controlling the defense of such claim shall keep the
other party fully informed of the status of such claim at all stages thereof,
whether or not such other party is represented by its own counsel, (iii) the
Company, Dennis Hayes or the Investor, as applicable, shall make available to
the indemnified party and its accountants and legal representatives all books
and records of the Company, Dennis Hayes or the Investor relating to such Third
Party Investor Indemnified Claims or Third Party Company Indemnified Claims, as
applicable, (iv) the parties shall render to each other such assistance as may
reasonably be requested in order to insure the proper and adequate defense of
such Third Party Investor Indemnified Claims or Third Party Company Indemnified
Claims, as applicable, and (v) the party controlling the defense of such claim
shall not make any settlement or claim without the written consent of the other
party, which consent shall not be unreasonably withheld. Without limiting the
generality of the foregoing, it shall not be unreasonable for an indemnified
party to withhold consent to a settlement that does not provide for the complete
and unconditional release of such indemnified party with respect to such Third
Party Investor Indemnified Claims or Third Party Company Indemnified Claims, as
applicable.

             7.7  No Impairment of Investors' Rights. Any examination or
inspection by audit of the properties, financial condition or other matters of
the Company and its Subsidiaries or their respective businesses or of Dennis
Hayes conducted by any Investor or their respective affiliates or
representatives prior to the Closing shall in no way limit, affect or impair the
ability of any Investor to rely upon the representations, warranties, covenants
and obligations of the Company and Dennis Hayes set forth in this Agreement or
otherwise limit the indemnification obligations set forth in this Article 7.

             8.   Miscellaneous.

             8.1  Survival of Warranties. The warranties and representations of
the Company, Dennis Hayes, and the Investors contained in or made pursuant to
this Agreement shall survive the execution and delivery of this Agreement and
the Closing for a period beginning on the date of Closing and expiring on the
earlier of (i) two (2) years from the date of Closing and (ii) the date of the
closing of the Company's initial public offering of its securities pursuant to a
Registration Statement declared effective by the Securities and Exchange
Commission, and shall in no way be affected by any investigation of the subject
matter thereof made by or on behalf of the Investors or the Company; provided,
however, that notwithstanding the foregoing, the representations and warranties
of Dennis Hayes and the Company set forth in Sections 2.2, 2.4, 2.5, 2.19, 2.21,
2.28, 2B.1, 2B.2, 2B.5 and 2B.6 (to the extent it relates to Sections 2.2, 2.4,
2.5, 2.19, 2.21 and 2.28) and their obligations to indemnify the Investor
Indemnitees pursuant to Article 7 hereof with respect to a breach thereof or
otherwise shall survive the Closing indefinitely; provided, further, that any
representation or warranty that is the subject of an outstanding written
indemnification claim on the date it would otherwise expire shall survive beyond
such date for purposes of such claim until such claim is finally resolved.

             8.2  Successors and Assigns. The terms and conditions of this
Agreement shall inure to the benefit of and be binding upon the respective
successors and permitted assigns of the parties. Nothing in this Agreement,
express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and assigns any rights, remedies,

                                     - 37 -

<PAGE>   38



obligations, or liabilities under or by reason of this Agreement, except as
expressly provided in this Agreement. The rights and obligations of the parties
hereto may not be assigned without the express written consent of the other
parties hereto; provided however, that each Investor may assign its respective
rights and obligations to a wholly owned direct or indirect subsidiary of such
Investor, so long as such assignment is not made at a time which would cause a
delay in or interfere with the Closing or cause a breach of this Agreement; and
provided further that no assignment by an Investor shall relieve such Investor
from or diminish or affect such Investor's obligations hereunder.

             8.3 Governing Law. This Agreement shall be governed by and
construed under the laws of the State of Georgia without reference to its
conflicts of law principles. Any action brought hereunder shall be heard by a
court sitting in the County of Fulton, State of Georgia.

             8.4 Counterparts. This Agreement may be executed in one or more

in connection with the negotiation, preparation, execution and consummation of
this Agreement, including the fees, expenses and disbursements of their legal
counsel incurred in connection herewith.

             8.9  Amendments and Waivers. Except as otherwise provided with
respect to the Investors purchasing a majority of the Preferred Shares, any term
of this Agreement may be amended and the observance of any term of this
Agreement may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company
and the Investors.

             8.10 Severability. If one or more provisions of this Agreement are
held to be unenforceable under applicable law, such provision shall be excluded
from this Agreement and the balance of this Agreement shall be interpreted as if
such provision were so excluded and shall be enforceable in accordance with its
terms.

             8.11 Entire Agreement. This Agreement, the respective
Confidentiality Agreements between the Company and the Investors (or their
affiliates) dated June 4, 1995, March 29, 1996 and October 1, 1995 (the
"Confidentiality Agreements), the Exhibits and Schedules attached hereto, the
Schedule of Exceptions and the other documents and agreements delivered pursuant
hereto constitute the full and entire understanding and agreement among the
parties with regard to the subjects hereof and thereof and supersedes any prior
agreements (including any memorandum of understanding or letters of intent)
between the parties regarding the subject matter hereof. Notwithstanding the
foregoing, the parties agree that Section 7 entitled "Standstill" of the
Confidentiality Agreements shall automatically terminate at the Effective Time,
and any provision in any such agreement which would prohibit any public
announcements which would be permitted under Section 8.12 hereof is hereby
terminated. Any other confidentiality or nondisclosure agreements or letters
between the Company and any of the Investors are hereby terminated as of the
date hereof. The parties further agree that any and all provisions contained in
any of the above referenced Confidentiality Agreements which would prohibit the
disclosure of the fact that any investigations, discussions or negotiations are
taking place between the parties concerning the transactions contemplated hereby
are hereby terminated as of the date hereof. The letter agreement of Hayes in
favor of Acma, dated on or about March 30, 1996, is not superseded by and
expressly survives this Agreement and the closing of this transaction.

             8.12 Public Announcements. No party shall make any public
announcement of the execution of this Agreement or the transactions contemplated
hereby without first obtaining the prior consent of the other parties hereto (or
in the case of the Investors' prior consent, the consent of the Investors
purchasing a majority of the Preferred Shares); provided however, that nothing
contained herein shall prohibit any party hereto from making any public
announcement that such party determines in good faith, is required by applicable
law or the rules or regulations of any applicable securities exchange; provided,
that in such event, such party shall use its reasonable efforts to consult with
the other parties hereto prior to making such disclosure and in any case will
promptly notify all other parties of such disclosure.

             8.13 Further Assurances. Each party covenants that at any time, and
from time to time, after the date of Closing, it will execute such additional
instruments and take such

                                     - 41 -

actions as may be reasonably requested by the other parties to confirm or
perfect or otherwise to carry out the intent and purposes of this Agreement.

             8.14 No Third Party Beneficiaries. This Agreement is not intended
for the benefit of and shall not create rights in any persons other than the
parties hereto and their respective successors and permitted assigns, except as
expressly contemplated otherwise in Section 1.1 hereof.

             8.15 Tax Consequences of the Parties. The parties agree that no
parties make any representations or warranties herein as to the tax consequences
of this Agreement and in the events and the actions contemplated hereby.

             8.16 Schedules and Exhibits Incorporated. All Schedules and
Exhibits attached hereto are incorporated herein by reference.

bequeath, pledge, assign, transfer or encumber in any manner whatsoever (all
such dispositions being hereinafter referred to as a "transfer" or "disposition"
and shall be deemed included in the verb "to dispose") any share of Stock or any

of this Shareholders' Agreement, except for dispositions permitted under Section
7. After the expiration of such two (2) year period, no Shareholder may transfer

transfers or dispositions permitted under Section 7, unless the Shareholder
seeking to make the transfer (the "Transferor") shall first have made the
written offer to sell described in Section 2.2 below (the "Offer") and that
Offer has not

                                       -7-

<PAGE>   8



been accepted pursuant to the terms of this Shareholders' Agreement, nor shall
any Investor transfer any Anti-Dilution Warrant other than in connection with a
transfer of Offered Shares.

         2.2 OFFER BY TRANSFEROR. The Offer referred to in Section 2.1 shall be
given by the Transferor to the Company and to each of the other Shareholders
(herein the "Non-Offering Shareholders") and shall consist of a written Offer to
sell all the Offered Shares of Stock which the Transferor then intends to
dispose of, to which Offer shall be attached a statement of intention to dispose
of the Offered Shares pursuant to a bona fide offer from a prospective purchaser
or purchasers (the "Transferee"), a description of the contemplated disposition,
the name and address of each bona fide Transferee, the number of shares of Stock
involved in and other terms (the "Terms") of the proposed disposition. The Terms
shall include, without limitation, the purchase price per Offered Share offered
by each Transferee and the manner in which such purchase price shall be paid to
the Transferor. Such Offer shall be signed by the Transferor and shall remain
irrevocable until the earlier of (a) the time at which all of the Offered Shares
are accepted by the Company or the Non-Offering Shareholders, as provided in
Sections 2.3 and 2.4 or (b) one hundred twenty (120) days after the "Offer
Date," which date shall be the date on which a notice is given to the Company
and such Non-Offering Shareholders in accordance with the terms of Section 14.2
of this Shareholders' Agreement. The date on which the Offer becomes revocable
is referred to herein as the "Expiration Date."

         2.3 ACCEPTANCE OF OFFER BY THE COMPANY. The Company may, at its option
exercised within sixty (60) days after the Offer Date, elect to purchase all or
any portion of the Offered Shares on the Terms (with the designees of the
selling Shareholder abstaining on any vote of the Board of Directors of the
Company with respect to such purchase). If and to the extent the Company does
not accept the Offer in accordance with this Section 2.3 with respect to all of
the Offered Shares, the Offered Shares may be disposed of in accordance with
Section 2.4. The Company shall exercise its option under this Section 2.3 by
giving an Exercise Notice. The Exercise Notice shall be in accordance with the
Terms. Any purchase by the Company of one hundred percent (100%) of the Offered
Shares shall be completed not later than ninety (90) days after the Offer Date
(subject to any extension of time required to permit necessary governmental or
regulatory filings, notices or approvals).

         2.4 ACCEPTANCE OF OFFER BY SHAREHOLDERS. If and to the extent the
Company does not accept the Offer with respect to all of the Offered Shares in
accordance with the provisions of Section 2.3, the remaining Offered Shares
shall be deemed to be offered to the Non-Offering Shareholders and each
Non-Offering Shareholder may, at its option exercised within ten (10) days after
(i) the last day of the exercise period pursuant to Section 2.3 or, if earlier
(ii) the date on which the Company notifies the Shareholders of its election to
purchase less than all (or none) of the Offered Shares, elect to purchase not
more than its Proportion of the remaining Offered Shares. Each Non-Offering
Shareholder who exercises its option to purchase its Proportion of the Offered
Shares shall do so by giving an Exercise Notice. In the event that any such
Non-Offering Shareholder gives an Exercise Notice covering less than its
Proportion of the Offered Shares available to be purchased by Non-Offering
Shareholders (such shares not covered by Exercise Notices being referred to as
the "Balance"), each of the Non-Offering Shareholders that

                                       -8-

<PAGE>   9



timely delivered an Exercise Notice covering its full Proportion of the Offered
Shares available to be purchased by Non-Offering Shareholders, may, by a second
Exercise Notice delivered within ten (10) days after the expiration of the first
ten (10) day period referred to above, elect to purchase up to that number of
Offered Shares that is equal to the product of the Balance multiplied by a
fraction, the numerator of which shall be such Non-Offering Shareholder's
Proportion of the number of Offered Shares first made available for purchase by
Non-Offering Shareholders pursuant to this Section 2.4, and the denominator of
which shall be the total number of such Offered Shares covered by the first
Exercise Notices timely delivered by all Non-Offering Shareholders which
purchased their respective full Proportions. If, after the expiration of the
second ten (10) day period any Offered Shares remain available to be purchased,
any Non-Offering Shareholder which has timely delivered Exercise Notices
covering the maximum number of Offered Shares available to it, may notify the
Company, within five (5) days after the expiration of such second ten (10) day
period of its desire to purchase additional Offered Shares, specifying the
maximum number of such Offered Shares it is willing to purchase. If more than
one such notice is received by the Company, the number of additional Offered
Shares shall be allocated to the Non-Offering Shareholders delivering such
notices in the same proportion as their respective offers bear to the total
number of Offered Shares available in the third and final round.


         2.5 PURCHASES BY COMPANY AND SHAREHOLDERS. If the Company and the
Non-Offering Shareholders together, or the Non-Offering Shareholders (or any of
them) alone, elect to purchase 100% of the Offered Shares, the sale and purchase
of such shares shall be completed not later than one hundred and five (105) days
after the Offer Date (subject to any extension of time required to permit
necessary governmental or regulatory filings, notices or approvals). The
Transferor shall not be obligated to sell any Offered Shares to the Company or
to any Non-Offering Shareholder unless the Company and/or the Non-Offering
Shareholders have agreed to purchase, and purchase, 100% of the Offered Shares.
"Completion" of any sale pursuant to this Article 2 shall mean, at a minimum,
delivery by the selling Shareholder to each purchaser of certificate(s)
representing the number of shares of Stock to be sold, in form for transfer by
delivery, and payment by each purchaser of the purchase price therefor in
accordance with the Terms, or as may otherwise be agreed by the parties.

3.       CO-SALE RIGHTS.

         3.1 CO-SALE RIGHTS OF NON-OFFERING SHAREHOLDER. If the Company and the
Non-Offering Shareholders do not accept the Offer with respect to all of the
Offered Shares in accordance with the provisions of Sections 2.3 and 2.4, each
Non-Offering Shareholder may, by an Exercise Notice given to the Transferor not
earlier than ninety (90) days and not later than one hundred and twenty (120)
days after the Offer Date, elect to participate in such sale on the same terms
and conditions as the Terms pursuant to the formula set forth in Section 3.2 of
this Shareholders' Agreement. To the extent that a Non-Offering Shareholder
elects so to participate in such sale, the number of shares of Stock that the
Transferor may sell in the transaction shall be correspondingly reduced.


                                       -9-

<PAGE>   10



         3.2 SHARES ELIGIBLE FOR CO-SALE. Each Non-Offering Shareholder may sell
all or any part of that number of shares of Stock held by it or him, equal to
the product obtained by multiplying (i) the aggregate number of shares of Stock
covered by the Offer by (ii) a fraction (A) the numerator of which is the number
of shares of Stock (on an as-converted basis for all Preferred Shares) owned by
such Non-Offering Shareholder at the date of the Offer and (B) the denominator
of which shall be the sum of the total number of shares of Stock owned by the
Transferor at the date of the Offer and the total number of shares of Common
Stock (on an as-converted basis for all Preferred Shares) owned at the date of
the Offer by all Non-Offering Shareholders that desire to participate in such
sale pursuant to this Article 3.

         3.3 PARTICIPATION. Each Non-Offering Shareholder shall effect its
participation in a sale by promptly delivering to Transferor for transfer to the
prospective purchaser one or more certificates, properly endorsed for transfer,
which represent the number of shares of Common Stock which such Non-Offering
Shareholder elects to sell or that number of Preferred Shares which (on an
as-converted basis) is convertible into the number of shares of Common Stock
which such Non-Offering Shareholder elects to sell. The Transferor shall hold
such shares for such Non-Offering Shareholder pending the consummation of the
sale transaction.

         3.4 TRANSFER OF STOCK. The stock certificate or certificates that each
Non-Offering Shareholder delivers to the Transferor pursuant to Section 3.3
shall be transferred to the prospective purchaser upon the consummation of the
sale of the Stock pursuant to the Terms and any and all purchase agreements
agreed to by the parties, and the Transferor shall concurrently therewith remit
to such Non-Offering Shareholder that portion of the sale proceeds to which such
Non-Offering Shareholder is entitled by reason of its participation in such
sale. To the extent that any prospective purchaser refuses to purchase Stock
from a Non-Offering Shareholder, the Transferor shall not sell to such
prospective purchaser any shares of Stock unless and until, simultaneously with
such sale, the Transferor shall purchase from such Non-Offering Shareholder
(pursuant to the Terms) that number of shares of Stock which such Non-Offering
Shareholder had the right, pursuant to this Article 3, to sell to such
prospective purchaser.

4.       SALE OF OFFERED SHARES TO TRANSFEREE.

         If the Non-Offering Shareholders and the Company do not elect to
purchase all of the Offered Shares in accordance with the terms of Sections 2.3
and 2.4 and the Non-Offering Shareholders do not elect to exercise their co-sale
rights in accordance with the terms of Article 3, the Transferor shall not be
obligated to sell any of the Offered Shares to the Non-Offering Shareholders or
the Company or to reduce the number of Offered Shares which such Transferor may
sell in accordance with Article 3 and shall be entitled to dispose of all of the
Offered Shares to the Transferee on the Terms, PROVIDED that such disposition is
consummated within one hundred fifty (150) days (subject to any extension of
time required to permit necessary governmental or regulatory filings, notices or
approvals) after the Offer Date and the Transferee executes a counterpart of
this Shareholders' Agreement and agrees to remain bound by all terms of this
Shareholders' Agreement. Any proposed transfer on terms and conditions other
than the Terms, as well as any subsequent proposed transfer of any Stock by such
Shareholder, shall again

                                      -10-

<PAGE>   11



be subject to the rights of the Company and the Non-Offering Shareholders and
shall require compliance by Transferor with the procedures described in Articles
2 and 3.

5.       RIGHT OF FIRST REFUSAL WITH RESPECT TO NEW SECURITIES.

         The Company hereby grants to each Shareholder, the right of first
refusal to purchase, pro rata, all (or any part) of any New Securities that the
Company may from time to time propose to sell and issue. Such Shareholder's pro
rata share, for purposes of this right of first refusal, is the ratio of the
number of shares of Stock (on an as-converted basis) held by such Shareholder as
compared to the total number of outstanding shares of Stock (on an as-converted
basis). This right of first refusal shall be subject to the following
provisions:

                           (a) In the event that the Company proposes to
                  undertake an issuance of New Securities, it shall give each
                  Shareholder written notice of its intention, describing the
                  type of New Securities, the price, and the general terms upon
                  which the Company proposes to issue the same. Each Shareholder
                  shall have twenty (20) days from the date such notice is given
                  to agree to purchase its pro rata share of such New Securities
                  for the price and upon the general terms specified in the
                  notice by giving written notice to the Company and stating
                  therein the quantity of New Securities to be purchased. Each
                  purchasing Shareholder shall have a right of overallotment
                  such that if any Shareholder fails to exercise its right
                  hereunder to purchase its pro rata portion of New Securities,
                  the Company shall so notify the purchasing Shareholders and
                  the purchasing Shareholders may, upon notice given within ten
                  (10) days after the date on which they are notified that
                  additional New Securities are available, purchase the New
                  Securities otherwise allocable to any nonpurchasing
                  Shareholder on a pro rata basis (based on the number of shares
                  of Stock (on an as converted basis) held by such
                  Shareholders).

                           (b) If the Shareholders fail timely to exercise such
                  right of first refusal as to 100% of the New Securities
                  proposed to be issued, then the Company shall have one hundred
                  twenty (120) days after the expiration of the applicable
                  exercise period(s) provided in subsection (a) above to sell
                  the New Securities at a price and upon general terms no more
                  favorable to the purchasers thereof than were specified in the
                  Company's notice to the Shareholders of such proposed
                  issuance. In the event the Company has not sold the New
                  Securities within such one hundred twenty (120) day period,
                  the Company shall not thereafter issue or sell any New
                  Securities, without first offering such securities to the
                  Shareholders in the manner provided above.

6.       EFFECTS OF NON-PARTICIPATION

condition precedent to such transfer, such transferee, if requested by the
Company or by any other party hereto, shall sign a counterpart of this

of Article 2 as applicable to any proposed sale of shares of Stock by such
organization, of Section 8.2 insofar as the provisions of either such Section
require a sale of shares of Stock by such shareholder, and of Section 14.1
hereof.

                  Any Shareholder making any such transfer will promptly notify
the Company and each other Shareholder thereof, and Schedule 1 hereto shall be
amended promptly after the giving of any such notice.

8.       CERTAIN  RIGHTS OF INVESTORS AND THE PRINCIPAL SHAREHOLDER.

         8.1 At any time after the fourth (4th) anniversary of the date of this
Shareholders' Agreement, when Rinzai is a shareholder of the Company and an
Initial Public Offering has not been completed, Rinzai may, with the full
cooperation of the Company and the other Shareholders, and utilizing the
resources of the Company, retain, subject to the approval of the Board of
Directors of the Company, which approval shall not be unreasonably withheld, a
reputable investment banker or other appropriate professional advisor on behalf
of the Company to seek an Acquisition Offer from a third party (the customary
fees of which investment banker or other professional will be paid by the
Company) and in the event that such investment banker or other professional is
successful in soliciting an Acquisition Offer then the terms of Section 8.2 of
this Shareholders' Agreement shall apply; PROVIDED, HOWEVER, that the customary
fees of such investment banker or professional, which may be based on a
successful sale of the Company as an entirety, shall be borne by each
Shareholder ratably according to its respective shareholdings if the shares of
Stock held by Rinzai are purchased by other Shareholders pursuant to Section 8.2
of this Shareholders' Agreement.

         8.2 (a) If at any time after the fourth (4th) anniversary of the date
of this Shareholders' Agreement, when Rinzai is a shareholder of the Company and
no Initial Public Offering has been completed, an Acquisition Offer (whether or
not solicited as contemplated by Section 8.1) is made by a third party and
Rinzai desires to accept such Acquisition Offer in accordance with its terms, it
shall notify the Company and the other Shareholders in writing (a "Liquidity
Notice") of such desire and shall provide to the Company and the other
Shareholders any and all information as to such Acquisition Offer that Rinzai
may have that has not been delivered to the other parties by the offeror. Any
Liquidity Notice shall include a prominent caption or other conspicuous
reference to this Section 8.2(a) and state that it is a "Liquidity Notice."

             (b) Within thirty (30) days after the giving of a Liquidity Notice,
each of the other Shareholders shall advise the Company and Rinzai of his or its
desire to accept such Acquisition Offer or to reject it. Unless all of the other
Shareholders desire to accept such Acquisition Offer, then within forty (40)
days after the giving of the Liquidity Notice, the Company shall advise Rinzai
and the other Shareholders of the number of shares, if any, of Stock held by
Rinzai that the Company desires to purchase. If this number of shares is less
than one

                                      -13-

<PAGE>   14



hundred percent (100%) of the number of shares of Stock owned by Rinzai, then
each of the other Shareholders may purchase any remaining shares of Rinzai
ratably in accordance with their ownership of Stock. If any of the other
Shareholders is entitled to but declines so to purchase Rinzai's shares of
Stock, the purchasing Shareholders, as the case may be, may purchase all such
remaining shares. The Shareholders shall advise Rinzai of his or its election so
to purchase shares from Rinzai by written notice given not later than fifty (50)
days after the giving of the Liquidity Notice.

                  (c) If the Company and the other Shareholders do not,
collectively, so elect to purchase one hundred percent (100%) of the shares of
Stock owned by Rinzai, then all Shareholders will be deemed to have accepted the
Acquisition Offer and each of the Shareholders will, if Board of Directors
approval is required for the transaction, cause the members of the Board of
Directors of the Company appointed by them, respectively, to vote in favor of
acceptance of the Acquisition Offer, and, together with any Shareholder
transferee that is a charitable organization subject to the provisions of
Article 7, will sell the shares of Stock or otherwise perform the obligations of
shareholders of the Company under and pursuant to such documents as may govern
the consummation of the Acquisition Offer.

           8.3    Each sale pursuant to Section 8.2 of this Shareholders'
Agreement shall be on the following terms and conditions:

                           (a) The purchase price shall be a price per share
                  equal to that of the Acquisition Offer (PROVIDED that Rinzai
                  agrees to accept cash in lieu of non-cash property
                  contemplated by such Acquisition Offer to be transferred as
                  part of the purchase price thereunder, in an amount equivalent
                  to the fair market value of any such non-cash property, as
                  such fair market value is determined by a reputable,
                  qualified, independent appraiser, selected by Rinzai and
                  acceptable to the purchasing Shareholder(s) in their
                  reasonable judgment);

                           (b) The obligations of Rinzai with respect to such
                  sale shall be substantially similar to those contained in the
                  Acquisition Offer;

                           (c) The sale shall be consummated within sixty (60)
                  days (subject to any extension of time required to permit
                  necessary governmental or regulatory filings, notices or
                  approvals) after the date of the Liquidity Notice (or on or
                  before such later closing date as may be contemplated by the
                  Acquisition Offer); and

                           (d) Any or all of the Shareholders, as applicable,
                  shall and shall cause the Company to (if applicable),
                  simultaneously with the receipt of the certificate or
                  certificates for the shares to be sold by Rinzai pursuant to
                  this Article 8, pay the aggregate purchase price therefor, as
                  specified in this Article 8, in immediately available funds by
                  wire transfer to an account maintained with a United States
                  bank, as designated by Rinzai, or by other means acceptable to
                  Rinzai and such purchasers.

         8.4 No Shareholder shall have any obligation to solicit or accept,
other than from Dennis C. Hayes as Principal Shareholder or from his guardian or
the executor or administrator of his estate, in either case, as the Person who
has succeeded to the Principal Shareholder's rights and obligations hereunder,
any request or instruction under this Shareholders' Agreement, including,
without being limited to, this Article 8 or Article 9.

9.       REGISTRATION RIGHTS.

         9.1 Request for Registration. If the Company shall receive at any time
after the completion of an Initial Public Offering, a written request from
Holders holding at least twenty percent (20%) of the Registrable Securities then
outstanding (the "Initiating Holders") that the Company file a registration
statement under the Securities Act on Form S-1 covering the registration of the
Registrable Securities then outstanding and such registration would cover sales
having an anticipated aggregate offering price, net of underwriting discounts
and commissions, equal to or more than Ten Million Dollars (US $10,000,000),
then the Company shall, within twenty-one (21) days after receipt thereof, give
written notice of such request to all Holders and shall, subject to the
limitations of subsections 9.1(a), (b) and (c), file as soon as practicable a
registration statement under the Securities Act covering all Registrable
Securities which the Holders request to be registered within twenty (20) days
after the date such notice is given by the Company in accordance with Section
14.2.

                           (a) Notwithstanding the foregoing, the Company shall
                  not be obligated to take any action to effect any such
                  registration pursuant to this Section 9.1:

                                    (i)   in any particular jurisdiction in
                           which the Company would be required to execute a
                           general consent to service of process in effecting
                           such registration, unless the Company is already
                           subject to service in such jurisdiction and except as
                           may be required by the Securities Act;

                                    (ii)  if the Company shall have initiated a
                           registration pursuant to this Section 9.1 within the
                           preceding six (6) month period;

                                    (iii) if the Company shall have initiated at
                           the request of such Initiating Holder(s) at least one
                           such registration pursuant to this Section 9.1 which
                           has been declared or ordered effective;

                                    (iv)  if the Initiating Holders propose to
                           dispose of shares of Registrable Securities which may
                           be immediately registered on Form S-3 pursuant to a
                           request made under Section 9.11 hereof; or

                                    (v)   at any time after five (5) years
                           immediately following completion of the Initial
                           Public Offering.

                           (b) Subject to the foregoing subsection 9.1(a), the
                  Company shall file a registration statement as soon as
                  possible after receipt of the request or requests of the
                  Initiating Holders under this Section 9.1 and the Company
                  shall have the right, subject to the other provisions of this
                  Section 9.1, to participate therein; PROVIDED, HOWEVER, that
                  if the Company shall furnish to such Initiating Holders within
                  thirty (30) days of receipt of such request a certificate
                  signed by the CEO of the Company stating that in the good
                  faith judgment of the Board of Directors of the Company it
                  would be detrimental to the Company and its shareholders for
                  such registration statement to be filed on or before the date
                  filing would be required and it is therefore essential to
                  defer the filing of such registration statement, the Company
                  shall have the right to defer such filing to a date not later
                  than one hundred eighty (180) days after receipt of such
                  request; PROVIDED, FURTHER, that notwithstanding anything to
                  the contrary herein, the Company shall not be obligated to
                  effect a registration pursuant to this Section 9.1 during the
                  period starting with the date of the Initial Public Offering
                  and ending on the date one hundred eighty (180) days following
                  the Initial Public Offering, PROVIDED that the Company employs
                  all reasonable efforts to cause such registration statement to
                  become effective and the Company's estimate of the date of
                  filing such registration statement is made in good faith.

                           (c) The underwriting shall be managed by a reputable
                  underwriter or underwriters selected by the Initiating
                  Holders, which selection shall be subject to the consent of
                  the Company, which consent shall not be unreasonably withheld,
                  and the Company shall have the right, subject to the other
                  provisions of this subsection (c), to participate therein. The
                  right of any Holder to registration pursuant to Section 9.1
                  shall be conditioned upon such Holder's participation in such
                  underwriting and the inclusion of such Holder's Registrable
                  Securities in the underwriting. The Company shall (together
                  with all Holders proposing to distribute their securities
                  through such underwriting) enter into an underwriting
                  agreement in customary form with the underwriter or
                  underwriters selected as provided above. Notwithstanding any
                  other provision of this Section 9.1, if the underwriters
                  advise the Initiating Holders and the Company in writing that
                  marketing factors require a limitation of the number of shares
                  to be underwritten and that the total amount of securities
                  that all Holders (Initiating and non-Initiating) and the
                  Company request pursuant to this Section 9.1(c) to be included
                  in such offering exceeds the amount of securities that the
                  underwriters reasonably believe compatible with the success of
                  the offering, the Company shall so advise all Holders and all
                  of the shares to be included in the registration shall be
                  allocated among all Holders requesting inclusion (Initiating
                  and non-Initiating) pro rata according to the total amount of
                  securities requested to be included in such registration owned
                  by each Holder requesting inclusion (Initiating or
                  non-Initiating) or in such other proportions as shall be
                  mutually agreed by such selling shareholders, and only if all
                  of the shares requested to be included by Holders are

                                      -16-

<PAGE>   17



                  included after giving effect to such allocation shall any
                  shares requested by the Company to be included be included.

         If any Person does not agree to the terms of any such underwriting, it
shall be excluded therefrom by written notice from the Company or the
underwriter. Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration. If
shares are so withdrawn from the registration, the Company shall then offer to
all Persons who have retained the right to include securities in the
registration the right to include additional securities in the registration in
an aggregate amount equal to the number of shares so withdrawn, with such shares
to be allocated among the Persons requesting additional inclusion pro rata
according to the total amount of securities requested to be included in such
registration owned by each such Person or in such other proportions as shall be
mutually agreed by such selling shareholders.

         9.2 COMPANY REGISTRATION. If at any time after the date of this
Shareholders' Agreement the Company proposes to register (including for this
purpose a registration effected by the Company for shareholders other than the
Holders) any of its stock or other securities under the Securities Act in
connection with the public offering of such securities solely for cash (other
than a registration relating solely to the sale of securities to participants in
a Company stock plan, or a registration relating to shares to be issued in
connection with the acquisition of another company, or a registration on any
form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder made within thirty (30) days after the Company shall have given such
notice in accordance with Section 14.2, the Company shall, subject to the
provisions of Section 9.7, use all reasonable efforts to cause to be registered
under the Securities Act all of the Registrable Securities that each such Holder
has requested to be registered.

         9.3 OBLIGATIONS OF THE COMPANY. Whenever required under this Article 9
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

                           (a) Prepare and file with the SEC a registration
                  statement with respect to such Registrable Securities and use
                  all reasonable efforts to cause such registration statement to
                  become effective, and, upon the request of the Holders of a
                  majority of the Registrable Securities registered thereunder,
                  keep such registration statement effective for up to one
                  hundred twenty (120) days;

                           (b) Prepare and file with the SEC such amendments and
                  supplements to such registration statement and the prospectus
                  used in connection with such registration statement as may be
                  necessary to comply with the provisions of the Securities Act
                  with respect to the disposition of all securities covered by
                  such registration statement;

                                      -17-

<PAGE>   18




                           (c) Furnish to the Holders such numbers of copies of
                  a prospectus, including a preliminary prospectus, in
                  conformity with the requirements of the Securities Act, and
                  such other documents as they may reasonably request in order
                  to facilitate the disposition of Registrable Securities owned
                  by them;

                           (d) Use all reasonable efforts to register and
                  qualify the securities covered by such registration statement
                  under such other securities or blue sky laws of such
                  jurisdictions as shall be reasonably requested by the Holders,
                  PROVIDED, HOWEVER, that the Company shall not be required in
                  connection therewith or as a condition thereto to qualify to
                  do business or to file a general consent to service of process
                  in any such states or jurisdictions; and

                           (e) Enter into and perform its obligations under an
                  underwriting agreement, in usual and customary form, with the
                  managing underwriter of such offering. Each Holder
                  participating in such underwriting shall also enter into and
                  perform its obligations under such an agreement.

         9.4 FURNISH INFORMATION. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Article 9 that
the selling Holders shall furnish to the Company such information regarding
themselves, the Registrable Securities held by them, and the intended method of
disposition of such securities as shall be reasonably and customarily required
to effect the registration of the Registrable Securities.

         9.5 EXPENSES OF DEMAND REGISTRATION. All expenses in connection with
the registrations initiated pursuant to Section 9.1 hereof and made or ordered
effective, other than underwriting discounts and commissions incurred in
connection with registrations, filings or qualifications pursuant to Section
9.1, including (without limitation) all registration, filing and qualification
fees, printers' and accounting fees, fees and disbursements of counsel for the
Company, and the reasonable fees and disbursements (not to exceed US $50,000) of
one counsel for the selling Holders, shall be borne by the Company; PROVIDED,
HOWEVER, that the Company shall not be required to pay for any expenses of any
registration proceeding begun pursuant to Section 9.1 if the registration
request is subsequently withdrawn at the request of the Holders (Initiating or
non-Initiating) holding a majority of the Registrable Securities to be
registered (in which case all participating Holders shall bear such expenses).

         9.6 EXPENSES OF COMPANY REGISTRATION. The Company shall bear and pay
all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 9.2 for each Holder (which right may be assigned as provided
in Section 9.12), including (without limitation) all registration, filing and
qualification fees, printers' and accounting fees relating or apportionable
thereto and the reasonable fees and disbursements (not to exceed US $50,000) of
one counsel for the selling Holders selected by them, but excluding underwriting
discounts and commissions relating to Registrable Securities.

         9.7 UNDERWRITING REQUIREMENTS. In connection with any offering
involving an underwriting of shares being issued by the Company, the Company
shall not be required under Section 9.2 to include any of the Holders'
securities in such underwriting unless such Holder accepts the terms of the
underwriting as agreed upon between the Company and the underwriters selected by
the Company, and then only in such quantity as will not, in the opinion of the
underwriters, jeopardize the success of the offering by the Company. If the
total amount of securities, including Registrable Securities, requested by
shareholders to be included in an offering (other than a registration effected
pursuant to Section 9.1) exceeds the amount of securities to be sold other than
by the Company that the underwriters reasonably believe compatible with the
success of the offering, then the Company shall be required to include in the
offering only that number of Registrable Securities which the underwriters
believe will not jeopardize the success of the offering (the securities so
included to be apportioned pro rata among the selling shareholders according to
the total amount of securities requested to be included therein owned by each
selling shareholder or in such other proportions as shall mutually be agreed to
by such selling shareholders).

         If any Person does not agree to the terms of any such underwriting, it
shall be excluded therefrom by written notice from the Company or the
underwriter. Any Registrable Securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration. If shares are so
withdrawn from the registration, the Company shall then offer to all Persons who
have retained the right to include securities in the registration the right to
include additional securities in the registration in an aggregate amount equal
to the number of shares so withdrawn, with such shares to be allocated among the
Persons requesting additional inclusion pro rata according to the total amount
of securities requested to be included in such registration owned by each such
Person or in such other proportions as shall be mutually agreed by such selling
shareholders.

         For purposes of the immediately preceding paragraph concerning
apportionment, for any selling shareholder which is a holder of Registrable
Securities and which is a partnership or corporation, the partners, retired
partners and shareholders of such holder, or the estates and family members of
any such partners and retired partners, and any trusts for the benefit of any of
the foregoing Persons shall be deemed to be a single "selling shareholder," and
any pro rata reduction with respect to such "selling shareholder" shall be based
upon the aggregate amount of shares carrying registration rights owned by all
entities and individuals included in such "selling shareholder," as defined in
this sentence.

         9.8 DELAY OF REGISTRATION. No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 9.

         9.9 INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under this Article 9:


                                      -19-

<PAGE>   20



                           (a) To the extent permitted by law, the Company will
                  indemnify and hold harmless each Holder, the officers,
                  directors, partners, employees and legal counsel of each
                  Holder, and each Person, if any, who controls such Holder
                  within the meaning of the Securities Act or the Exchange Act,
                  against any losses, claims, damages or liabilities (joint or
                  several) to which they may become subject under the Securities
                  Act, the Exchange Act or any other federal or state law, rule
                  or regulation insofar as such losses, claims, damages or
                  liabilities (or actions in respect thereof) arise out of or
                  are based upon any of the following statements, omissions or
                  violations (collectively, a "Violation"): (i) any untrue
                  statement or alleged untrue statement of a material fact
                  contained in such registration statement, including any
                  preliminary prospectus or final prospectus contained therein
                  or any amendments or supplements thereto, (ii) the omission or
                  alleged omission to state therein a material fact required to
                  be stated therein, or necessary to make the statements therein
                  not misleading in light of the circumstances in which they
                  were made, or (iii) any violation or alleged violation by the
                  Company of the Securities Act, the Exchange Act, any state
                  securities law or any rule or regulation promulgated under the
                  Securities Act, the Exchange Act or any state securities law;
                  and the Company will reimburse each such Holder, officer,
                  director, partner, employee, legal counsel, underwriter or
                  controlling Person for any legal or other expenses reasonably
                  incurred by them in connection with investigating or defending
                  any such loss, claim, damage, liability or action or enforcing
                  these indemnification provisions, as such expenses are
                  incurred; PROVIDED, HOWEVER, that the indemnity agreement
                  contained in this subsection 9.9(a) shall not apply to amounts
                  paid in settlement of any such loss, claim, damage, liability
                  or action if such settlement is effected without the consent
                  of the Company, nor shall the Company be liable in any such
                  case for any such loss, claim, damage, liability or action to
                  the extent that it arises out of or is based upon a Violation
                  which occurs in reliance upon and in conformity with written
                  information furnished expressly for use in connection with
                  such registration by any such Holder.

                           (b) To the extent permitted by law, each selling
                  Holder will indemnify and hold harmless the Company, each of
                  its directors and officers, its legal counsel, each Person, if
                  any, who controls the Company within the meaning of the
                  Securities Act, and any other Holder selling securities in
                  such registration statement or any of such other Holder's
                  directors, officers, employees, legal counsel or any Person
                  who controls such Holder, against any losses, claims, damages
                  or liabilities (joint or several) to which the Company or any
                  such director, officer, employee, legal counsel, or
                  controlling Person, or other such Holder or director, officer,
                  employee, legal counsel or controlling Person of such other
                  Holder may become subject, under the Securities Act, the
                  Exchange Act or other federal or state law, insofar as such
                  losses, claims, damages or liabilities (or actions in respect
                  thereto) arise out of or are based upon any Violation, in each
                  case to the extent (and only to the extent) that such
                  Violation occurs in reliance upon and in conformity with
                  written information furnished by such Holder

                                      -20-

<PAGE>   21



                  expressly for use in connection with such registration; and
                  each such Holder will reimburse any legal or other expenses
                  reasonably incurred by the Company or any such director,
                  officer, employee, legal counsel, controlling Person, other
                  Holder, or officer, director, employee, legal counsel, or
                  controlling Person of such other Holder in connection with
                  investigating or defending any such loss, claim, damage,
                  liability, or action or enforcing these indemnification
                  provisions, as such expenses are incurred; PROVIDED, HOWEVER,
                  that the indemnity agreement contained in this subsection
                  9.9(b) shall not apply to amounts paid in settlement of any
                  such loss, claim, damage, liability or action if such
                  settlement is effected without the consent of the indemnifying
                  Holder.

                           (c) Promptly after receipt by an indemnified party
                  under this Section 9.9 of notice of the commencement of any
                  action (including any governmental action), such indemnified
                  party will, if a claim in respect thereof is to be made
                  against any indemnifying party under this Section 9.9, give to
                  the indemnifying party a written notice of the commencement
                  thereof and the indemnifying party shall have the right to
                  participate in, and, to the extent the indemnifying party so
                  desires, jointly with any other indemnifying party similarly
                  noticed, to assume the defense thereof with counsel mutually
                  satisfactory to the parties; PROVIDED, HOWEVER, that an
                  indemnified party shall have the right to retain its own
                  counsel at its own expense if it so desires. Notwithstanding
                  the foregoing, if the indemnified party and the indemnifying
                  party have conflicting interests with respect to the action so
                  that joint counsel for them would be inappropriate (as
                  determined by counsel to the indemnified party and counsel to
                  the indemnifying party), then the indemnifying party shall pay
                  reasonable fees and expenses of one counsel to the indemnified
                  party. Each indemnified party shall give reasonably prompt
                  notice to each indemnifying party or parties of any action or
                  proceeding commenced against it in respect of which indemnity
                  may be sought hereunder, but the failure to deliver written
                  notice to the indemnifying party within a reasonable time of
                  the commencement of any such action, shall not relieve such
                  indemnifying party of any liability to the indemnified party
                  under this Section 9.9, unless the indemnifying party is
                  materially prejudiced by such failure to give notice.

                           (d) If the indemnification provided for in this
                  Section 9.9 is held by a court of competent jurisdiction to be
                  unavailable to an indemnified party or insufficient to hold
                  harmless an indemnified party under subsection (a), (b), or
                  (c) above, then each indemnifying party shall contribute to
                  the amount paid or payable by such indemnified party as a
                  result of the losses, claims, damages or liabilities referred
                  to in subsection (a), (b), or (c) above, in such proportion as
                  is appropriate to reflect the relative fault of the
                  indemnifying party on the one hand and of the indemnified
                  party on the other in connection with the action, statement or
                  omission that resulted in such claims, as well as other
                  equitable considerations. The relative fault shall be
                  determined with reference to, among other things, whether the
                  untrue statement or alleged omission to state a material fact
                  relates to

                                      -21-

<PAGE>   22



                  information supplied by the indemnifying party or such
                  indemnified party and the parties' relative intent, knowledge,
                  access to information and opportunity to correct or prevent
                  such statement or omission. Notwithstanding the foregoing
                  provisions of this Section 9.9, a Holder of Registrable
                  Securities shall not, as an indemnifying party, be required to
                  contribute any amount in excess of (x) the amount by which the
                  total price at which the Registrable Securities sold by such
                  indemnifying party were offered to the public exceeds (y) the
                  amount of any damages which such indemnifying party has
                  otherwise been required to pay by reason of such action,
                  untrue or alleged untrue statement or omission or alleged
                  omission. The Company and each Holder of Registrable
                  Securities agrees that it would not be just and equitable if
                  contribution pursuant to this Section 9.9(d) were determined
                  by pro rata allocation or by any other method of allocation
                  which does not take account of the equitable considerations
                  referred to above in this Section 9.9(d). The amount paid or
                  payable by an indemnified party as a result of the losses,
                  claims, damages or liabilities referred to above in this
                  Section 9.9(d) shall be deemed to include any legal or other
                  expenses reasonably incurred by such indemnified party in
                  connection with investigation or defense of any such action or
                  claim which is the subject of this subsection (d) or
                  enforcement of these contribution provisions.

                           (e) The obligations of the Company and Holders under
                  this Section 9.9 shall survive the completion of any offering
                  of Registrable Securities in a registration statement under
                  this Article 9, and otherwise.

           9.10   REPORTS UNDER SECURITIES EXCHANGE ACT. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration, the Company agrees that if it becomes a reporting company under
the Exchange Act, to:

                           (a) make and keep public information available, as
                  those terms are understood and defined in SEC Rule 144, at all
                  times after ninety (90) days after the effective date of the
                  first registration statement filed by the Company for the
                  offering of its securities to the general public;

                           (b) file with the SEC in a timely manner all reports
                  and other documents required of the Company under the
                  Securities Act and the Exchange Act; and

                           (c) furnish to any Holder, so long as the Holder owns
                  any Registrable Securities, forthwith upon request (i) a
                  written statement by the Company that it has complied with the
                  reporting requirements of SEC Rule 144 (at any time after
                  ninety (90) days after the effective date of the first
                  registration statement filed by the Company), the Securities
                  Act and the Exchange Act (at any time after it has become
                  subject to such reporting requirements), and (ii) a copy of
                  the most recent

                  annual or quarterly report of the Company and such other
                  reports and documents so filed by the Company.

           9.11   FORM S-3 REGISTRATION. In case the Company shall receive
written request or requests from a Holder that the Company effect a registration
on Form S-3 and any related qualification or compliance with respect to all or a
part of the Registrable Securities owned by such Holder or Holders, the Company
will:

                           (a) promptly give written notice of the proposed
                  registration, and any related qualification or compliance, to
                  all other Holders; and

                           (b) as soon as practicable, effect such registration
                  and all such qualifications and compliances as may be so
                  requested and as would permit or facilitate the sale and
                  distribution of all such portion of such Holder's or Holders'
                  Registrable Securities as are specified in such request,
                  together with all or such portion of the Registrable
                  Securities of any other Holder or Holders joining in such
                  request as are specified in a written request made within
                  thirty (30) days after the Company shall have given such
                  notice pursuant to Section 14.2 hereof; PROVIDED, HOWEVER,
                  that the Company shall not be obligated to effect any such
                  registration, qualification or compliance pursuant to this
                  Section 9.11: (i) if Form S-3 is not available for such
                  offering by the Holders; (ii) if the Holders, together with
                  the holders of any other securities of the Company entitled to
                  inclusion in such registration, propose to sell Registrable
                  Securities and such other securities (if any) at any aggregate
                  price to the public of less than Five Million Dollars (US
                  $5,000,000); (iii) if the Company shall furnish to the Holders
                  a certificate signed by the CEO stating that in the good faith
                  judgment of the Board of Directors it would be seriously
                  detrimental to the Company and its stockholders for such Form
                  S-3 Registration to be effected at such time, in which event
                  the Company shall have the right to defer the filing of the
                  Form S-3 Registration Statement for a period of not more than
                  one hundred eighty (180) days after receipt of the request of
                  the Holder or Holders under this Section 9.11; PROVIDED,
                  HOWEVER, that the Company shall not utilize this right more
                  than once in any 12 month period; (iv) if the Company within
                  the nine month period preceding the date of such request,
                  already has effected one registration on Form S-3 for the
                  Holders pursuant to this Section 9.11 or within the 48 month
                  period preceding the date of such request already has effected
                  five such registrations and other similar provisions granting
                  rights to the registration on Form S-3; or (v) in any
                  particular jurisdiction in which the Company would be required
                  to qualify to do business or to execute a general consent to
                  service of process in effecting such registration,
                  qualification or compliance.

                  Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered (including securities which the Company wishes to
issue), as soon as practicable after receipt of the request or requests

                                      -23-

<PAGE>   24



of the Holders. All expenses, other than underwriting discounts and commissions,
incurred in connection with the registrations pursuant to this Section 9.11,
including (without limitation) all other registration, filing, qualification,
printer's and accounting fees shall be borne by the Company. Registrations
effected pursuant to this Section 9.11 shall not be counted as demands for
registration effected pursuant to Section 9.1 of this Shareholders' Agreement.

         9.12 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the Company
to register Registrable Securities pursuant to this Article 9 may be assigned by
a Holder to a transferee or assignee who has lawfully received the shares in
accordance with all applicable laws and regulations and with respect to
Registrable Securities other than Board Warrants, the terms of this
Shareholders' Agreement and, if applicable, is a Shareholder as defined
hereunder or a partner or equity holder of a Shareholder (or a third party duly
authorized to act on behalf of a Shareholder or its partners or equity holders),
PROVIDED that such partner or equity holder has appointed such Shareholder (or
such duly authorized third party) as its lawful attorney-in-fact to receive
notices, vote and otherwise make binding decisions under the terms of this
Article 9; PROVIDED, HOWEVER, in each case, the Company is, within a reasonable
period of time after such transfer, given written notice of the name and address
of such transferee or assignee and the securities with respect to which such
registration rights are being assigned; and PROVIDED, FURTHER, that such
assignment shall be effective only if (i) immediately following such transfer
the further disposition of such securities by the transferee or assignee is
restricted under the Securities Act and (ii) the transferee agrees to be bound
by the terms of this Article 9. Any provisions of this Shareholders' Agreement
to the contrary notwithstanding, a transferee shall have no rights of a Holder
under Section 9.1 of this Shareholders' Agreement unless such transferee
receives from a Shareholder that is a party to this Shareholders' Agreement as
of its date, one hundred percent (100%) of the shares of Stock held by such
Shareholder as of the date of this Shareholders' Agreement (as diluted, other
than by disposition by such Shareholder).

         9.13 AMENDMENT OF REGISTRATION RIGHTS. Any provision of this Article 9
may be amended and the observance thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Company and the holders of at least seventy percent (70
%) of the Registrable Securities. Any amendment or waiver effected in accordance
therewith shall be binding upon each holder of any securities purchased under
this Shareholders' Agreement at the time outstanding (including securities into
which such securities are convertible), each future holder of all such
securities, and the Company.

         9.14 TERMINATION OF REGISTRATION RIGHTS. The Company's obligations
pursuant to this Article 9 shall terminate five (5) years after the date of
consummation of the Initial Public Offering.

         9.15 "MARKET STAND-OFF" AGREEMENT. Each Holder hereby agrees that it
shall not, to the extent requested by the Company and an underwriter of Common
Stock (or other securities) of the Company, sell or otherwise transfer or
dispose of any securities of the Company (other than securities registered in
the offering) whether or not acquired by such Holder under this Shareholders'
Agreement during a reasonable and customary period of time (not to exceed

                                      -24-

<PAGE>   25



one hundred eighty (180) days), as agreed to by the Company and the
underwriters, following the effective date of a registration statement of the
Company filed under the Securities Act; PROVIDED, HOWEVER, that:

                           (a) such agreement shall be applicable only to the
                  first registration statement of the Company which covers
                  shares (or securities) to be sold on its behalf to the public
                  in an underwritten offering; and

                           (b) all officers and directors of the Company,
                  holders of 5% or more of the Company's issued and outstanding
                  capital stock and all other Persons with registration rights
                  (whether or not pursuant to this Shareholders' Agreement)
                  similarly agree not to sell or transfer.

In order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and the
shares or securities of every other Person subject to the foregoing restriction)
until the end of such reasonable and customary period.

10.      COVENANTS OF THE COMPANY AND THE SHAREHOLDERS.

         10.1 FINANCIAL STATEMENTS. The Company shall deliver to each
Shareholder (i) as soon as practicable, but in any event within ninety (90) days
after the end of each fiscal year of the Company, an income statement for such
fiscal year, a balance sheet of the Company as of the end of such year, and a

                           Agreement);

                           hereunder, then the Investor asserting a breach shall
                           have given the Company and each other party to this

                           this Section 10.5 and more than twenty (20) days
                           shall have elapsed without such breach being remedied
                           (or the effect thereof waived by such Investor);

         10.6     CHIEF EXECUTIVE OFFICER.

                  The Shareholders will implement the following procedure as
promptly as is practicable after the Closing Date:

                           (a) Promptly (and in any event within ten (10) days
                  after the Closing Date if no chief executive officer ("CEO")
                  has been appointed by the Board), a committee of the Board of
                  Directors of the Company, consisting of three members, with
                  one member appointed by each of Rinzai, the Principal

                  prospective president and CEO candidates to be formally
                  nominated by the Chairman to the Board, subject to the prior
                  approval of the Investors holding a majority of the Preferred

                  appointment by the Board to such position. The

                  qualifications, objectives and responsibilities of the CEO
                  will include at least the items set forth on the description
                  attached hereto as Exhibit C.

                           (b) If a CEO has not been appointed by the Board
                  acting on a nomination initiated by the Chairman within ninety
                  (90) days after the Closing Date, then the Investors, acting
                  jointly, shall thereafter have the right, subject to approval
                  by the Chairman, to determine which CEO candidates are
                  formally nominated for appointment by the Board. Such
                  candidates may be identified by the Board committee, any
                  Shareholder, the Chairman, or any executive recruiter employed
                  by or on behalf of any of the foregoing, PROVIDED only that if
                  the Investors owning a majority of the Preferred Shares have
                  agreed on a candidate who substantially fulfills the
                  requirements inherent in the description attached as Exhibit C
                  and whom they wish formally to nominate, they will first
                  advise the Chairman and request his approval (which approval
                  shall not be unreasonably withheld). If the Chairman rejects
                  the first two such candidates, he shall approve any third
                  candidate so selected to be nominated or, if he prefers one of
                  the two candidates previously rejected and that candidate is
                  still available and willing to accept such position, the
                  Chairman may approve such previously rejected candidate.

                           (c) The Company shall enter into an employment
                  agreement with the CEO, the terms of such employment agreement
                  to be subject to the approval of the Investors owning a
                  majority of the Preferred Shares, which approval shall not be
                  unreasonably withheld PROVIDED that the description of the
                  position of CEO set forth in such contract is substantially
                  identical to the description attached hereto as Exhibit C, and
                  the prior approval of the Investors owning a majority of the
                  Preferred Shares shall be required for any amendment or
                  modification of such contract (or any contract with any
                  successor CEO during the 24-month period following the Closing
                  Date) the effect of which is to reduce the objectives and
                  responsibilities of such position.

                           (d) Any CEO appointed pursuant to this procedure may
                  be removed only by the Board of Directors.

                           (e) In the event of a vacancy in the CEO position
                  (including any vacancy existing on the Closing Date), so long
                  as Rinzai is a Shareholder of the Company, Rinzai shall in its
                  sole discretion be entitled to appoint an interim CEO until
                  such position can be filled either in accordance with the
                  terms of this Section 10.6 or by a vote of the Board of
                  Directors of the Company in the event that the terms of this
                  Section 10.6 are no longer applicable.

If a chief financial officer of the Company is appointed at any time after the
Closing Date, the foregoing procedure (but with reference to an appropriate
position profile for chief financial

                                      -30-

<PAGE>   31



officer) shall apply also to such appointment. The above procedure shall apply
to the first and any successor CEO and CFO appointed during the term hereof.

agreements between the Shareholders contained elsewhere in this Shareholders'
Agreement or in any other document entered into after the date hereof, the

                  professional proposed by Rinzai in accordance with the
                  provisions of Section 8.1 of this Shareholders' Agreement.

                           (c) Each Shareholder will cause the members of the

                  Date, the Shareholders will hold a meeting at which, among
                  other things, Directors will be elected, and immediately

                  shall without further action by any party hereto, terminate
                  and be of no further force or effect.

         Upon execution of this Shareholders' Agreement, each Shareholder shall
deliver to the Secretary of the Company all certificates evidencing shares of
Stock then owned by him or it, which certificates shall be stamped or endorsed
with a legend in substantially the following form:

                               TRANSFER RESTRICTED

"THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON
TRANSFER CONTAINED IN A SHAREHOLDERS' AGREEMENT DATED AS OF APRIL 16, 1996 (THE
"AGREEMENT") AMONG HAYES MICROCOMPUTER PRODUCTS, INC. (THE "COMPANY") AND THE

ENCUMBERED OR OTHERWISE DISPOSED OF EXCEPT IN ACCORDANCE THEREWITH. A COPY OF
THE AGREEMENT IS ON FILE AT THE OFFICES OF THE COMPANY AND MAY BE OBTAINED
WITHOUT CHARGE UPON WRITTEN REQUEST TO THE PRESIDENT OF THE COMPANY.

IN ADDITION, THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES LAWS OF ANY STATE OF THE
UNITED STATES. THESE SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE
SOLD OR OFFERED FOR SALE AND NO TRANSFER OF THEM WILL BE MADE BY THE COMPANY OR

a legend substantially in the following form:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES.

Stock shall have provided the Company with an opinion

                                      -32-

from counsel, in form and substance acceptable to the Company and from attorneys
reasonably acceptable to the Company, stating that a public sale, transfer or
assignment of such Stock may be made without registration.

12.      BOARD OF DIRECTORS.

           12.1   ELECTION. The Board of Directors shall initially consist of
seven (7) members. Directors shall be elected as hereinafter set forth. Subject
to the provisions of Section 12.2 of this Shareholders' Agreement, each of the
Shareholders shall vote (or cause to be voted) all of the shares of Stock owned
or controlled by him or it so as to provide for the election to the Board of
Directors, at any annual or special meeting called for such purpose, of (i) the
Principal Shareholder and one individual designated by the Principal Shareholder
or the Principal Shareholder Successor (or two (2) individuals designated by the
Principal Shareholder Successor if the Principal Shareholder is deceased or
incompetent); (ii) two (2) individuals designated by Rinzai; (iii) one (1)
individual designated jointly by the Singapore Group; (iv) one (1) individual
designated by the Hong Kong Group who shall be nominated by Kaifa Technology

(but not any interim CEO). Each Shareholder and the Principal Shareholder
Successor agrees to vote to remove any Director at the request of the
Shareholder or the Principal Shareholder Successor that designated such
Director. The rights of the Principal Shareholder and each Investor so to
designate Directors shall inure to the benefit of any transferee pursuant to
Article 4 hereof from such Shareholder (or from the Principal Shareholder
Successor or, as to the Investor, from any Permitted Transferee) of all (but not
less than all) of the shares of Stock originally issued to such Shareholder (as
the same may have been converted and adjusted for stock splits, combinations and
other similar events). Any Shareholder who owns at least two percent (2%) of the
issued and outstanding Stock, calculated on a fully diluted basis, and who does
not have the right to nominate a Board member as provided above, shall have the
right to receive notice of and attend all Board meetings for observation
purposes, but shall not have the right to vote or otherwise participate therein
nor to attend any meeting, or portion thereof, declared by the Board, upon
advice of counsel, to be a closed meeting for executive session; and provided,
further, that any such Shareholder who does not attend any such meeting shall
have the right to receive copies of any minutes or resolutions approved by the
Board at such meeting.

         12.2     ALTERATION OR TERMINATION OF PROVISIONS UNDER CERTAIN 
CIRCUMSTANCES.

                           (a) If at any time the number of shares of Stock
                  owned or controlled by any of the Principal Shareholder, the
                  Principal Shareholder Successor or Rinzai (or by any Article 4
                  transferee of any thereof who is entitled, pursuant to the
                  provisions of Section 12.1, to designate Directors) shall be
                  less than twenty percent (20%) of the then outstanding shares
                  of Stock by reason of any sale or other disposition made by
                  such Shareholder or the Principal Shareholder Successor, as
                  the case may be, then (i) such Shareholder or the Principal
                  Shareholder Successor, as the case may be, shall be entitled
                  to designate only one Director in accordance with Section 12.1
                  and shall forthwith cause the resignation of one of the two
                  Directors at the time holding office in the Company by reason
                  of the designation thereof by such Shareholder or the
                  Principal Shareholder Successor, respectively, and (ii) the
                  Bylaws of the Company shall promptly be amended so as to
                  implement the foregoing provisions. If at any time the number
                  of shares of Stock owned or controlled by any of the Principal
                  Shareholder, the Principal Shareholder Successor, Rinzai, the
                  Hong Kong Group or the Singapore Group (or by any Article 4
                  transferee of any thereof who is entitled, pursuant to the
                  provisions of Section 12.1, to designate Directors) shall be
                  less than eight percent (8%) of the then outstanding shares of
                  Stock by reason of any sale or other disposition made by such
                  Shareholder or the

                                      -33-

<PAGE>   34



                  Principal Shareholder Successor, as the case may be, then (i)
                  such Shareholder or the Principal Shareholder Successor, as
                  the case may be, shall not be entitled to designate any
                  Directors in accordance with Section 12.1 and shall forthwith
                  cause the resignation of the Director or Directors at the time
                  holding office in the Company by reason of the designation
                  thereof by such Shareholder or the Principal Shareholder
                  Successor, respectively, and (ii) the Bylaws of the Company
                  shall promptly be amended so as to implement the foregoing
                  provisions.

                           (b) If at any time the Principal Shareholder and his
                  Permitted Transferees, the Employee Plan and Rinzai, or any
                  Investor (or the Hong Kong Group or the Singapore Group) if
                  such Investor (or group of Investors) has acquired more than
                  twenty percent (20%) of the Company's outstanding Stock, are
                  the only shareholders of the Company, then the number of
                  Directors shall be reduced to five (5), a quorum of the
                  Directors shall be reduced to three (3), and each of the
                  Principal Shareholder and Rinzai, or such Investor or group of
                  Investors, as the case may be, shall be entitled in accordance
                  with Section 12.1 to designate two (2) members of the Board of
                  Directors and such members acting jointly shall designate the
                  fifth (5th) member, PROVIDED that from and after such time as
                  any Investor or group of Investors owns at least fifty-five
                  percent (55%) of the outstanding shares (and the Principal
                  Shareholder and his Permitted Transferees and the Employee
                  Plan own the remainder), such Investor or group of Investors
                  shall be entitled to designate three (3) such Directors and
                  the Principal Shareholder shall be entitled to designate two
                  (2) such directors. The Bylaws of the Company shall be
                  promptly amended so as to implement the foregoing provisions.

           12.3   INDEMNIFICATION. The Articles of Incorporation or Bylaws of
the Company shall, at all times during which any Affiliate or employee of any
Shareholder serves as a member of the Board provide for limitations on the
liability of the Directors and indemnification of the Directors to the fullest
extent permitted under applicable law. To the extent not prohibited by law, in
the event that any Shareholder who is a Director or any Affiliate or employee of
a Shareholder who is a Director shall be made or threatened to be made a party
to any action, suit or proceeding with respect to which any such Shareholder or
Director may be entitled to indemnification solely in such capacity by the
Company pursuant to this Shareholders' Agreement or the Bylaws, or otherwise,
all such Directors, as a group, shall be entitled to be represented in such
action, suit or proceeding by one counsel of their choice and the expenses of
such representation shall be reimbursed by the Company on a monthly basis upon
submission of such invoices. Promptly after election of any director, the
Company will enter into an appropriate indemnification agreement with such
Director; PROVIDED, HOWEVER, that except with respect to proceedings to enforce
rights of indemnification, the Company shall indemnify any such Director for his
expenses incurred in connection with a successful proceeding (or part thereof)
initiated by such Director in such capacity only if such proceeding (or part
thereof) was authorized by the Board of Directors.

against them and transferees of securities of the Company which are subject to
this Shareholders' Agreement (in addition to any other remedies available for

the case of the Shareholders, transferees of their securities of the Company),
hereby waive the defense in any equitable proceeding that there is an adequate
remedy at law for any such breach.

an Initial Public Offering until the tenth (10th) anniversary of the date hereof
with respect to private sales (or series of related sales) of Stock for amounts
in the aggregate greater than Ten Million Dollars (US$10,000,000) and the

Offering until the fifth (5th) anniversary thereof.

<PAGE>   10



Invention, as defined herein, which is being used or studied by the Company and
is not described in a printed patent, described in any literature already
published and distributed externally by the Company, and which is not readily
ascertainable from inspection of a product of the Company, (ii) any engineering,
technical, or product specifications including those of features to be used, or

to the public (except when such public disclosure has been made by Executive or
another person or entity without authorization by the Company), or (B) that has
been independently developed and disclosed by parties other than the Executive
or the Company to the public generally or to the Executive without a breach of
any obligation of non-disclosure by any such parties running directly or

property of the Company, and that any of the Confidential Information or Trade
Secrets produced by him shall be considered proprietary to the Company. The
Executive agrees: (i) immediately to disclose solely to the Company all
Confidential Information and Trade Secrets developed in whole or in part by him
during the term of his employment with the Company; (ii) to assign to the
Company any right, title or interest he may have in such Confidential

Trade Secrets including, without limitation, providing to the Company his full
cooperation in any litigation, unless between the Executive and the Company

any event upon termination of his employment with the Company for any reason,
the Executive shall promptly deliver to the Company all property belonging to
the Company, including, without limitation, all Confidential Information and
Trade Secrets (and all embodiments thereof) then in his custody, control or

                          7. INVENTIONS AND TRADEMARKS.

         7.1      Definition of Invention and Executive Invention.

                  7.1.1 For the purposes of this Section 7, Invention shall mean
any discovery, whether or not patentable, including, but not limited to, any
useful process, method, formula, technique, machine, manufacture, composition of
matter, algorithm or computer program, as well as improvements thereto, which is
new or which the Executive has a reasonable basis to believe may be new.

                  7.1.2 For the purposes of this Section 7, Executive Invention
shall mean any Invention which is conceived by the Executive or conceived by the
Executive in a joint effort with others during the Executive's employment by the
Company which (i) may be reasonably expected to be used in a current product of
the Company, a projected future product of the Company, or a product similar to
a Company product; (ii) results from work that the Executive has been assigned
as part of his duties as an employee, officer or director of the Company; (iii)
is in an area of technology which is the same or substantially related to the
areas of technology with which the Executive is involved in the performance of
the Executive's duties as an employee, officer or director of the Company; (iv)
is useful, or which may reasonably be expected to be useful, in any
manufacturing process, product design or internal control system of the Company;
or (v) is in an area of technology which includes machinery or processes with
which the Executive normally works in performing his duties as an employee,
officer or director of the Company.

         7.2 Property of the Company. The Executive hereby agrees that all
Executive Inventions shall become the property of the Company. The Company makes
no claim of rights to any Inventions of the Executive which are not Executive
Inventions, except to the extent that, by operation of law, the "shop rights
doctrine" provides the Company with any such rights.

         7.3 Conception of Invention. The Executive hereby agrees that if he
conceives any Invention during his employment, for which there is a reasonable
basis to believe that the conceived Invention may be an Executive Invention, the
Executive will provide notice containing a written description of the Invention
to each Board member, adequate to allow evaluation thereof by the Board for a
determination of whether the Invention is an Executive Invention.

         7.4 Patent Registration. The Executive hereby agrees that should the
Company elect to file any application for patent protection either in the United
States or in any foreign country on an Executive Invention, the Executive will
execute all necessary papers and documents, including formal assignments to the
Company, relating to such patent application. The Executive further agrees that
he will cooperate with any attorneys or other persons designated by the Company
by explaining the nature of the Executive Invention, reviewing applications and
other papers, and providing any other assistance reasonably required for the
orderly prosecution of the patent applications.

<PAGE>   12



         7.5 Discontinuance of Use. On or after the termination of the Term, the
Executive may request that the Board approve the transfer or assignment to the
Executive of a (i) patent or an Executive invention which existed during the
Term but has not been practiced or used for a period of one (1) year or more
prior to the Executive's request therefor or (ii) trademark, service mark or
tradename which was owned by the Company during the Term but has not been used
for a period of one (1) year or more prior to the Executive's request therefor.
The Board shall make a determination with respect to such transfer or assignment
and the value thereof in its sole discretion.

         7.6 Survival. The provisions of this Section 7 shall continue after the
Term as provided herein and shall survive irrespective of the reason for the
Executive's termination.

                      8. BREACH OF COVENANTS BY EXECUTIVE.

         The Executive agrees that the covenants and agreements contained in
Sections 5, 6 and 7 of this Agreement are of the essence of this Agreement and
that each of such covenants is reasonable and necessary to protect and preserve
the interests and properties of the Company and the Business of the Company. The
Executive further agrees that the Company is engaged in and through the Area in
the Business of the Company and that irreparable loss and damage will be
suffered by the Company should the Executive breach any of such covenants and
agreements. Each of such covenants and agreements is separate, distinct and
severable not only from the other of such covenants and agreements but also from
the other and remaining provisions of this Agreement and the unenforceability of
any such covenant or agreement shall not affect the validity or enforceability
of any other such covenants or agreements or any other provision or provisions
of this Agreement. The Executive acknowledges that damages are inadequate for
any breach of Sections 5, 6 or 7, and that the Company shall, whether or not it
is pursuing any potential remedies at law, be entitled to equitable relief in
the form of both temporary and permanent injunctions to prevent a breach or
contemplated breach by the Executive of any of such covenants or agreements. The
Executive shall further be liable for damages, if any, resulting from any breach
of such covenants and agreements.

                           9. RESOLUTION OF DISPUTES.

         9.1 Resolution of Disputes and Mediation. Except for the matters set
forth in Sections 5, 6, and 7 hereof, any dispute between the parties either
with respect to the interpretation of any provision of this Agreement or with
respect to the performance by the Executive or by the Company hereunder (the
"Dispute") shall be resolved in accordance with this Section 9 as follows:

             9.1.1    Upon the written request of either party hereto, each
                      of the parties shall appoint a designated
                      representative, whose task it shall be to meet for
                      the purpose of endeavoring to resolve the Dispute.
                      The Company's designated representative shall be a
                      member of the Board excluding (i) the Executive and
                      (ii) the Board member selected by the Executive to be
                      a Board member.

                  9.1.2    The designated representatives shall meet as often as
                           necessary to gather and furnish to the other all
                           information with respect to the Dispute which is
                           appropriate and germane in connection with its
                           resolution.

                  9.1.3    Such representatives shall discuss the Dispute and
                           negotiate in good faith in an effort to resolve the
                           Dispute without the necessity of any formal
                           proceeding relating thereto.

                  9.1.4    During the course of such negotiations all reasonable
                           requests made by one party to the other for
                           non-privileged information reasonably related to the
                           Dispute, shall be honored in order that each of the
                           parties may be fully advised of the other's position.

                  9.1.5    The specific format for such discussions shall be
                           left to the discretion of the designated
                           representatives but may include the preparation of
                           agreed upon statements of fact or written statements
                           of position furnished to the other party.

         9.2 Judicial Resolution. If the parties hereto are not able to resolve
the Dispute concerning this Agreement as set forth in Section 9.1 above within
sixty (60) calendar days, upon the initial written request as provided in
Section 9.1.1, then the parties shall have the option and right to resolve such
Dispute by judicial or other equitable resolution.

                               10. MISCELLANEOUS.

         10.1 Key Man Insurance. The Executive agrees that during the Term, the
Company in its sole discretion may purchase in addition to those specified in
Section 3.9.1 insurance policies on the Executive's life with the Company as the
primary beneficiary, provided that all costs of such insurance are paid by the
Company.

         10.2 Assignment. This Agreement may not be assigned by any party hereto
without the prior written agreement of the other party hereto.

         10.3 Severability. If any provision of this Agreement shall be held to

maximum extent permissible so as to effect the intent of the parties, and the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

         10.4 Beneficiary. All of the terms and provisions of this Agreement
shall be binding upon and inure to the benefit of and be enforceable by the
parties hereto and their respective successors, heirs, executors, administrators
and permitted assigns.

the Revolving Loan Agreement, this Agreement supersedes all prior and
contemporaneous agreements,

                                     - 13 -

understandings, negotiations and discussions, written or oral, of the parties
hereto, relating to the subject matter of this Agreement. Nothing in this
Agreement is intended or shall confer upon or give any person other than the
parties hereto any rights or remedies under or by reason of this Agreement.

         10.6 No Amendments. No amendments or modifications of this Agreement

by the Board and signed by a Board member duly authorized by the Board (other
than a Board member designated by the Executive or the Executive), or upon the
Executive unless made in writing and signed by the Executive.

         10.7 Waiver. The waiver by either party hereto of a breach by the other
party of any provision of this Agreement shall not operate or be construed as a
waiver of any subsequent breach of the same or any other provision by the
breaching party.

         10.8 Notices. Any notice required or permitted to be given hereunder
shall be in writing and delivered personally or by facsimile/telecopy

And the Investors Shown on Schedule 1 hereto

                          RE: INDEMNIFICATION AGREEMENT

Dear Sirs:

                  This letter will set forth my personal binding obligation and
agreement ("Agreement") to provide indemnification to Rinzai Limited ("Rinzai")
and the other Investors under that certain Agreement and Plan of Merger dated
April 12, 1996 (the "Agreement"), related to any actions, suits, proceedings,
claims or demands of Gary J. Franza, John Stuckey and Mikhail Drabkin ("Employee
Actions") as set forth below.

                  1.       I acknowledge that Hayes Microcomputer Products, Inc.
                           ("Hayes") has undertaken to indemnify the Investors
                           against Employee Actions as provided in Section
                           7.1(d) of the Agreement. It is my intention by virtue
                           of this Agreement to provide further indemnification
                           to the Investors for Employee Actions as stated
                           below.

                  2.       In the event that the Employee Actions as finally
                           adjudicated pursuant to a nonappealable order results
                           in an aggregate liability to the Company, or if the
                           Employee Actions are settled for an amount, in excess
                           of $2,000,000 (the "Excess Amount"), then I hereby
                           agree to indemnify the Investors for such Excess
                           Amount in the following manner. I will transfer to
                           each of the Investors a number of shares of my stock
                           in Hayes equal in value to each Investor's
                           proportional share (based on their relative

                           shareholdings in Hayes) of the Excess Amount. The
                           number of shares of stock shall be determined by
                           dividing the Excess Amount by the value per share of
                           the Hayes stock at the time of final adjudication of
                           liability or settlement of the Employee Actions. The
                           value per share of Hayes stock shall be determined as
                           follows:

                           (i)      If the Company has completed an initial
                                    public offering ("IPO") and its stock is
                                    publicly traded, the value per share shall
                                    be deemed to be the average closing price
                                    per share for each of the twenty (20) days
                                    prior to the final adjudication of liability
                                    or settlement, on NASDAQ/NMS or other
                                    exchange where Hayes shares are traded; or

                           (ii)     If Hayes has not completed an IPO at the
                                    time of the final adjudication of liability
                                    or settlement, then the value per share of
                                    Hayes stock shall be (i) for a period of six
                                    (6) months from the date of the Closing
                                    under the Agreement, US$7.14 and (ii)
                                    thereafter the total value of Hayes divided
                                    by the total number of issued and
                                    outstanding shares (on a fully diluted basis
                                    taking into account any then-exercisable
                                    options and warrants). The total value of
                                    Hayes shall be determined by the average of
                                    two (2) reputable nationally recognized
                                    appraisers, one selected by Rinzai and one
                                    selected by Dennis C. Hayes. The two
                                    appraisers' determinations shall be made in
                                    accordance with appropriate procedures and
                                    protocols to be established by Rinzai and
                                    Dennis C. Hayes at the time. For example,
                                    Rinzai and Dennis C. Hayes may instruct the
                                    appraisers to give full market value to the
                                    intellectual property estate and patent
                                    estate of Hayes for purposes of performing
                                    their valuation of Hayes. The appraisers
                                    shall complete their valuation within thirty
                                    (30) days after the date of appointment of
                                    both appraisers and the arithmetic average
                                    of the two valuations determined by the two
                                    appraisers shall be final, binding and
                                    conclusive on the parties.

                           The total value as established in (ii) above shall be
                           divided by the total issued and outstanding shares
                           (on a fully diluted basis taking into account any
                           then-exercisable options and warrants) of Hayes to
                           arrive at the value per share. The Excess Amount
                           shall then be divided by the value per share of the
                           Hayes stock determined by either paragraph 2(i) or
                           (ii) above,

                           and the resulting number of shares shall be
                           distributed to the Investors in proportion to their
                           shareholdings as a percentage of all issued and
                           outstanding shares of Hayes.

                  3.       In the event that any shares of stock in Hayes are
                           required to be transferred pursuant to any Employee
                           Action to any one of the Employees pursuant to a
                           final, nonappealable court order or settlement, then
                           I agree to transfer such shares to the Employees from
                           my own shares and neither the Company nor the
                           Investors shall have any responsibility for issuing
                           any new shares to the Employees.

                  It is understood that the Company will defend all Employee
Actions and will bear the cost of defense of such Employee Actions. It is my
further understanding that I, as Chairman of the Company in complete compliance
with my fiduciary duties as an officer of the Company (which fiduciary duties
shall not be altered or influenced in any way by my obligations under this
agreement), will be responsible for overall direction of the litigation of the
Employee Actions, although any settlement will be subject to approval of the
Board of Directors.

                  This letter constitutes my binding obligation to indemnify the
Investors as above stated. It is given for valuable consideration in the amount
of Ten Dollars ($10.00), as an inducement to the Investors to enter into the
Agreement and other good and valuable consideration and is given without any
undue influence or duress.

                                              Very truly yours,

                                              /s/ Dennis C. Hayes

                       HAYES MICROCOMPUTER PRODUCTS, INC.
                             VOTING TRUST AGREEMENT

          THIS VOTING TRUST AGREEMENT (the "Voting Trust") is made and
entered into this 16th day of April, 1996, by and among DENNIS C. HAYES, an
individual resident of Georgia ("Dennis C. Hayes"), HAYES MICROCOMPUTER
PRODUCTS, INC., a Georgia corporation (the "Corporation"), and G. DONALD
JOHNSON, as Trustee herein (hereinafter, along with any successors, referred to
as "Trustee").

                              W I T N E S S E T H :

          WHEREAS,  Dennis C. Hayes owns voting stock in the Corporation; and

          WHEREAS, pursuant to the terms of that certain Shareholders' Agreement
dated April 16, 1996, by and between the Corporation, Dennis C. Hayes, Rinzai
Limited, ("Rinzai"), Kaifa Technology (H.K.) Limited, Rolling Profit Holdings
Limited, Saliendra Pte. Ltd., Lao Hotel (H.K.) Limited, and S.P. Quek
Investments Pte Ltd., (as amended from time to time in accordance with the terms
thereof, the "Shareholders' Agreement,"), and the parties have agreed that
494,322 shares of the Corporation's stock owned by Dennis C. Hayes shall be held
in a nonvoting trust on the terms and conditions herein set forth; and

          WHEREAS, capitalized terms herein shall have the same meaning as
defined in the Shareholders' Agreement unless specified otherwise.

          NOW, THEREFORE, for and in consideration of the mutual covenants
contained herein, the sum of Ten Dollars ($10.00) in hand paid, and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto do hereby agree as follows:

1. TRANSFER OF SHARES BY DENNIS C. HAYES.  Upon the execution of this Voting 
   Trust, Dennis C. Hayes shall transfer and deposit with the Trustee 494,322
   shares of the Common Stock, which constitutes ten percent (10%) of the total
   number of shares of Common Stock "owned or controlled" (as such terms are
   defined in the Shareholders' Agreement) by him on the date hereof, by 
   delivering to the Trustee the certificates for such stock, duly endorsed in
   blank or accompanied by proper instruments of assignment and transfer thereof
   duly executed in blank, said shares to be held by the Voting Trust. All 
   shares of the Common Stock so transferred to the Trustee shall be registered 
   on the books and records of the Corporation as follows: "G. Donald Johnson as
   Trustee of the HAYES MICROCOMPUTER PRODUCTS, INC. VOTING TRUST under 
   agreement


<PAGE>   2



         dated April 16, 1996." If G. Donald Johnson or any subsequent Trustee
         ceases serving as Trustee herein, the shares of Common Stock held
         herein shall be so registered in the name of the applicable successor
         Trustee on behalf of the Voting Trust.

2.       VOTING TRUST CERTIFICATES. Upon the receipt by the Trustee of the
         certificates evidencing Dennis C. Hayes' Common Stock, the Trustee
         shall issue to Dennis C. Hayes a certificate evidencing his interest in
         the Voting Trust, said certificate to be in substantially the form set
         forth on Exhibit "A" attached hereto and by this reference incorporated
         herein (hereinafter referred to as the "Trust Certificate").

3.       VOTING BY TRUSTEE.  During the term of this Voting Trust, all shares 
         of Common Stock or any other interest in the Corporation with voting
         rights held in the Voting Trust (such Common Stock or other interests
         shall be referred to as the "Voting Interests") shall confer upon the
         Trustee the full and complete right to vote on all applicable matters
         of the Corporation for which such Voting Interests are entitled to
         vote; however, the Trustee shall not vote the Voting Interests and
         shall only abstain from voting on all such matters. Furthermore, the
         Trustee shall not grant a proxy to anyone for such vote during the term
         of this Voting Trust. It is expressly understood and agreed that no
         voting right shall pass to any person or entity other than the Trustee
         by or under the Trust Certificates or by or under this Voting Trust, or
         by or under any other agreement, express or implied, until the
         termination of the Voting Trust with respect to any Trust Property as
         defined below in Section 4.

4.       OTHER SHAREHOLDER ACTION.  Subject to the restriction on exercising 
         any and all rights to vote associated with any of the property held in 
         the Voting Trust (all such property held in the Voting Trust herein 
         shall be referred to as the "Trust Property"), the Trustee shall be 
         entitled to all of the rights and privileges conferred upon an owner 
         of the Trust Property ("Nonvoting Rights"). With respect to the 
         Nonvoting Rights, the Trustee shall act or fail to act with respect to 
         the specific Trust Property which was contributed by, issued or 
         delivered on behalf of the respective holders of the Trust 
         Certificates, in accordance with the written instructions by such 
         holder (or his/its successors or permitted assigns) to the Trustee. 
         However, the Trustee shall not be required to act or fail to act with
         respect to the Nonvoting Rights which the Trustee reasonably believes
         will expose the Trustee to damages, claims, investigations, charges 
         (civil or criminal), costs or will otherwise result in any harm to the 
         Trustee.  In the event the Trustee acts in accordance with such 
         instructions, then the holder of the Trust Certificate that provided 
         such instructions shall indemnify and hold the Trustee harmless against
         damages, losses and costs of any kind (including costs of investigation
         and attorneys fees) from any such action or omission by the Trustee. In
         the event the Trustee shall not receive such written instructions with
         respect to the exercise or failure to exercise Nonvoting Rights, the
         Trustee may act or not act with respect to the Nonvoting Rights and
         with respect to all other duties of the Trustee not specifically
         addressed hereunder, in accordance with the exercise of the Trustee's
         reasonable judgment. However, the Trustee shall assume no

                                        2


<PAGE>   3



         responsibility with respect to and shall not be liable for any action
         taken or any omission by him or his agents and no Trustee shall incur
         any responsibility by reason of any error of law or of any thing done
         or omitted unless such act or omission was (i) grossly negligent, or
         (ii) the result of willful misconduct. In the event the Trustee acts or
         fails to act with respect to Nonvoting Rights without instruction by
         the applicable holder of the Trust Certificate, and if the Trustee has
         acted or failed to act in accordance with the preceding two sentences,
         then the Holder of the applicable Trust Certificate shall indemnify and
         hold the Trustee harmless against damages, losses and costs of any kind
         (including costs of investigation and attorneys fees) from any such
         action or omission by the Trustee. No Trustee shall be required to post
         or give a bond or other security for the discharge of his or her
         duties. In the event the Trustee, in his capacity as Trustee of the
         Voting Trust, becomes party to, prosecutes, defends or intervenes in
         any legal action or proceeding pertaining to the Trust Property, then
         the holders of the Trust Certificates shall indemnify and hold the
         Trustee harmless against damages, losses and costs of any kind
         (including costs of investigation and attorneys fees) from any such
         action or proceeding so long as the Trustee's participation in such
         action or proceeding was in good faith and/or on the advice of counsel
         and was neither grossly negligent nor constituted willful misconduct.
         The Trustee shall not be an officer, director, shareholder, agent,
         consultant (other than legal counsel) or employee of the Corporation.

5.       DIVIDENDS.  Throughout the term of this Voting Trust, the Trustee 
         shall, within ten (10) days of the date received, distribute to the
         holders of the Trust Certificates ("Certificate Holders") all cash
         dividends received by the Trustee with respect to the interests of each
         such Certificate Holder in the Voting Trust. Such cash dividends shall
         be distributed to each such Certificate Holder in an amount equal to
         the amount the Certificate Holder would have received had such
         Certificate Holder been the record owner of the interests represented
         by the Trust Certificate. All stock dividends received by the Trustee
         with respect to the Trust Property (including any stock splits) shall
         be retained by the Trustee and all such stock shall be subject to the
         terms of this Voting Trust as fully as if originally deposited by the
         Shareholders pursuant to the terms of this Voting Trust; provided,
         however, that upon the receipt of a stock dividend or following a stock
         split, the Trustee shall issue to the Certificate Holders such
         additional Trust Certificates as may be necessary to reflect the change
         in the number of shares of stock being held by the Trustee.

6.       COMPENSATION OF TRUSTEE.  The Trustee shall  receive  reimbursement 
         for all expenses reasonably incurred in carrying out the provisions of 
         the Voting Trust and shall receive compensation for acting as Trustee
         hereunder in a reasonable amount if the Trustee is not an attorney at
         law and if the Trustee is an attorney at law, the Trustee shall receive
         as compensation the standard hourly rate charged by such attorney at
         law for all time expended herewith as Trustee. The Trustee may employ
         counsel (and the Trustee shall be entitled to employ on behalf of the
         Voting Trust attorneys at the law firm in which Trustee is a partner or
         is employed) and such reasonable professional and other assistance as
         may be convenient for the fulfillment of the purposes of the Voting

         of such compensation, expense reimbursement, counsel or other
         assistance shall be borne by the Corporation.

7.       SUCCESSOR TRUSTEE. In the event of the removal, death or resignation of
         the Trustee, or the continued failure of the Trustee to act as Trustee,
         the Certificate Holders shall select a successor Trustee by unanimous
         vote. The Certificate Holders may by unanimous vote remove a Trustee.

8.       TRANSFERS AND RECORD OWNERSHIP.  Subject to the restrictions on 
         transfer of shares set forth in the Shareholders' Agreement, which
         restrictions shall apply, mutatis mutandis, to the Trust Certificates,
         the Trust Certificates shall be transferable at the office of the
         Trustee by the registered holder thereof either in person or by
         attorney duly authorized. Upon surrender thereof, according to such
         rules as the Trustee may from time to time establish, and until so
         transferred, the Trustee may treat the registered holder as the owner
         thereof for all purposes whatsoever. Every transferee of a Trust
         Certificate hereunder shall upon acceptance thereof become a party to
         this Voting Trust with the same force and effect as if such transferee
         had signed this Voting Trust and shall be included with the meaning of
         the term "Dennis C. Hayes" whenever used herein. The Trustee may, in
         its sole discretion, appoint a registrar for the Trust Certificates and
         may provide that Trust Certificates shall not be valid unless
         registered and countersigned by such registrar.

         from the date hereof, unless sooner terminated in accordance with the
         following and if terminated, the Trust Property pertaining to the
         applicable Certificate Holder shall be released from the Voting Trust
         and promptly delivered to such Certificate Holder, along with such
         other documents as may be necessary to transfer the ownership of the
         Trust Property into the name of the Certificate Holder, in exchange for

                                    than forty five percent (45%) of the total

                           (iv)     upon the sale of the Corporation by the sale
                                    of substantially all of its assets or any

                  If this Note is automatically converted, written notice in the
                  form attached hereto as Annex 2 shall be delivered to the
                  Holder of this Note at the address last shown on the records
                  of the Company for the Holder or given by the Holder to the
                  Company for the purpose of notice or, if no such address
                  appears or has been given, at the place where the principal
                  executive office or residence of the Holder is located,
                  notifying the Holder of the conversion to be effected,
                  specifying the principal amount of this Note to be converted
                  and the date on which such conversion will occur (or has
                  occurred), and calling upon the Holder to surrender to the
                  Company, in the manner and at the place designated, this Note.
                  As promptly as practicable after the automatic conversion of
                  this Note, the Company at its expense will issue and deliver
                  to the Holder of this Note a certificate or certificates for
                  the number of full shares of Series A Preferred Stock issuable
                  upon such conversion.

                           6.2.2. Mechanics and Effect of Conversion. No
                  fractional shares of Series A Preferred Stock shall be issued
                  upon conversion of this Note. In lieu of the Company issuing
                  any fractional shares to the Holder upon the conversion of
                  this Note, the Company shall pay to the Holder the amount of
                  outstanding principal that is not so converted, such payment
                  to be in the form of a check payable to the Holder. Upon
                  conversion of this Note and payment of any cash in lieu of
                  fractional shares, the Company shall be forever released from
                  all its obligations and liabilities under this Note.

                  6.3. No Impairment. The Company will not avoid or seek to
avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Company, but will at all times in good faith assist
in carrying out all the provisions of this Section 6 and in taking all such
action as may be necessary or appropriate in order to protect the conversion
rights of the Holder of this Note against impairment.

         7. Reservation of Stock Issuable Upon Conversion. The Company shall at
all times reserve and keep available out of its authorized but unissued shares
of Series A Preferred Stock solely for the purpose of effecting the conversion
of this Note such number of shares of Series A Preferred Stock (and shares of
Common Stock of the Company ("Common Stock") for issuance on conversion of such
Series A Preferred Stock) as shall from time to time be sufficient to effect the
conversion of this Note; and if at any time the number of authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) shall not be sufficient
to effect the conversion of the entire outstanding principal amount of this
Note, in addition to such other remedies as shall be available to the Holder,
the Company will use all reasonable efforts to take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) to the number of shares
that is sufficient for such purposes.

         8. Assignment. Subject to the restrictions on transfer described in
Section 10 below, the rights and obligations of the Company and the Holder of
this Note shall be binding upon and benefit the successors, assigns, heirs,
administrators and transferees of the parties. The rights and obligations of the
Company under this Note may not be assigned by the Company without the prior
written consent of the Holder.

         9. Waiver and Amendment. Any provision of this Note may be amended,
waived or modified only upon the written consent of the Company and the Holder;

protest and demand, notice of protest, demand and dishonor and nonpayment of
this Note and (ii) the defense of the statute of limitations in any action on
this Note to the extent permitted by law.

         10. Transfer of this Note or Securities Issuable on Conversion Hereof.
With respect to any offer, sale or other disposition of this Note or securities
into which this Note may be converted, the provisions of Section 7 of the
Shareholders' Agreement shall apply, mutatis mutandis, to the same extent as if
this Note and such securities were "Stock" (as defined in the Shareholders'
Agreement). Each Note thus transferred and each certificate representing the
securities thus transferred shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with the Act,
unless in the opinion of counsel for the Company such legend is not required in
order to ensure compliance with the Act. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions.

         11. Treatment of Note. To the extent permitted by generally accepted
accounting principles, the Company will treat, account and report this Note as

filed with federal, state or local tax authorities.

                                             Others' %age ownership MINUS Change

         New Shares   =   (Total Shares  -  Existing Shares)  x  Loan %age

         where:

         Total Shares =   Total number of shares outstanding and held by Holders
                          of Convertible Subordinated Promissory Notes entitled
                          to conversion in respect of the Shareholder Loan of
                          which this Note evidences a part, as determined
                          immediately after conversion

         Other        =   Aggregate number of shares of Stock (Common and 
                          Preferred)

         Shares           owned or controlled by all shareholders that are not 
                          Holders of Convertible Subordinated Promissory Notes 
                          entitled to conversion in respect of the Shareholder 
                          Loan of which this Note evidences a part, as 
                          determined immediately prior to conversion

         Holders'     =   Aggregate ownership of Stock of the Company,  
         %age             expressed as a percentage, by Holders of Convertible
         ownership        Subordinated Promissory Notes entitled to conversion
                          in respect of the Shareholder Loan of which this Note 
                          evidences a part, as determined immediately prior to 
                          conversion

         ownership
         
         Change        =  The percentage obtained by (1) dividing the
         aggregate        principal amount of the Shareholder Loan that is 
                          subject to conversion (and of which this Note 
                          evidences a part) by $1,000,000, and (2) multiplying 
                          the result by 1.4.
         
         New Shares    =  The number of shares of Series A Preferred Stock 
                          issuable to the Holder of this Note upon conversion 
                          of such Holder's ratable share of the aggregate 
                          Shareholder Loan amount converted (and used to 
                          determine "Change")
         
                                      -9-

Existing   =    The aggregate number of shares of Stock (Common and Preferred)
Shares          owned by all Holders of Convertible Subordinated Promissory
                Notes entitled to conversion in respect of the Shareholder 
                Loan of which this Note evidences a part, as determined 
                immediately prior to conversion 


Loan %age =     The result, expressed as a percentage, obtained by dividing the 
                principal amount of this Note entitled to conversion by the 
                aggregate amount of the Shareholder Loan entitled to conversion
                as part of the same conversion event


By way of example, if the number of Existing Shares owned by all Holders of
Convertible Subordinated Promissory Notes is 4,900,000 and the Other Shares
owned or controlled by all Shareholders that are not Holders of Convertible
Subordinated Promissory Notes is 5,100,000, and if the aggregate principal
amount of the Shareholder Loan that is subject to conversion is $13,000,000:

then  Total Shares = 5,100,000 x (49.0 + 18.2) / (51.0 - 18.2)
                     = 5,100,000 x 67.2 / 32.8
                     = 10,448,780 shares

After such conversion, Total shares outstanding and held by Holders of
Convertible Subordinated Promissory Notes, as determined immediately after
conversion, would represent

         10,448,780 / (10,448,780 + 5,100,000) = 0.672 or 67.2% of all 
outstanding shares in the corporation.

1996, to payment in full of the Superior Debt (as defined therein).

            4.1. Subrogation. Notwithstanding the subordination provided for in 
the foregoing provisions of this Section 4, the Holder's right to receive shares
of Series A Preferred Stock of the Company ("Series A Preferred Stock") (and any

Holder's sole remedy following the occurrence of an Event of Default and neither
such right of conversion nor any shares issuable or issued upon exercise of such
right by the Holder shall be exercisable by or payable to or receivable by the
holder of any Senior Indebtedness.

         5.       Prepayment. This Note may be prepaid in whole or in part, 
without penalty, at any time prior to its conversion in accordance with Section
6 hereof.

         6.       Conversion.

                  6.1.     Automatic Conversion. At the close of business on the
Maturity Date the entire unpaid principal amount of this Note and any accrued
and unpaid interest thereon shall be automatically converted into shares of
Series A Preferred Stock. The conversion shall be effected in accordance with
the formula attached hereto as Annex 1.

                  6.2.     Conversion Procedure.

                           6.2.1. Notice of Conversion Pursuant to Section 6.1.
                  If this Note is automatically converted, written notice in the
                  form attached hereto as Annex 2 shall be delivered to the
                  Holder of this Note at the address last shown on the records
                  of the Company for the Holder or given by the Holder to the
                  Company for the purpose of notice or, if no such address
                  appears or has been given, at the place where the principal
                  executive office or residence of the Holder is located,
                  notifying the Holder of the conversion to be effected,
                  specifying the principal amount of this Note to be converted
                  and the date on which such conversion will occur (or has
                  occurred), and calling upon the Holder to surrender to the
                  Company, in the manner and at the place designated, this Note.
                  As promptly as practicable after the automatic conversion of
                  this Note, the Company at its expense will issue and deliver
                  to the Holder of this Note a certificate or certificates for
                  the number of full shares of Series A Preferred Stock issuable
                  upon such conversion.

                  fractional shares of Series A Preferred Stock shall be issued
                  upon conversion of this Note. In lieu of the Company issuing
                  any fractional shares to the Holder upon the conversion of
                  this Note, the Company shall pay to the Holder the amount of
                  outstanding principal that is not so converted, such payment
                  to be in the form of a check payable to the Holder. Upon
                  conversion of this Note and payment of any cash in lieu of
                  fractional shares, the Company shall be forever released from
                  all its obligations and liabilities under this Note.

                  6.3. No Impairment. The Company will not avoid or seek to
avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Company, but will at all times in good faith assist
in carrying out all the provisions of this Section 6 and in taking all such
action as may be necessary or appropriate in order to protect the conversion
rights of the Holder of this Note against impairment.

                                       -4-

         7. Reservation of Stock Issuable Upon Conversion. The Company shall at
all times reserve and keep available out of its authorized but unissued shares
of Series A Preferred Stock solely for the purpose of effecting the conversion
of this Note such number of shares of Series A Preferred Stock (and shares of
Common Stock of the Company ("Common Stock") for issuance on conversion of such
Series A Preferred Stock) as shall from time to time be sufficient to effect the
conversion of this Note; and if at any time the number of authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) shall not be sufficient
to effect the conversion of the entire outstanding principal amount of this
Note, in addition to such other remedies as shall be available to the Holder,
the Company will use all reasonable efforts to take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) to the number of shares
that is sufficient for such purposes.

         8. Assignment. Subject to the restrictions on transfer described in
Section 10 below, the rights and obligations of the Company and the Holder of
this Note shall be binding upon and benefit the successors, assigns, heirs,
administrators and transferees of the parties. The rights and obligations of the
Company under this Note may not be assigned by the Company without the prior
written consent of the Holder.

         9. Waiver and Amendment. Any provision of this Note may be amended,
waived or modified only upon the written consent of the Company and the Holder;
PROVIDED, HOWEVER, that the Company hereby waives (i) presentment for payment,
protest and demand, notice of protest, demand and dishonor and nonpayment of
this Note and (ii) the defense of the statute of limitations in any action on
this Note to the extent permitted by law.

         10. Transfer of this Note or Securities Issuable on Conversion Hereof.
With respect to any offer, sale or other disposition of this Note or securities
into which this Note may be converted, the provisions of Section 7 of the
Shareholders' Agreement shall apply, mutatis mutandis, to the same extent as if
this Note and such securities were "Stock" (as defined in the Shareholders'
Agreement). Each Note thus transferred and each certificate representing the
securities thus transferred shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with the Act,
unless in the opinion of counsel for the Company such legend is not required in
order to ensure compliance with the Act. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions.

         11. Treatment of Note. To the extent permitted by generally accepted
accounting principles, the Company will treat, account and report this Note as

                          of Convertible Subordinated Promissory Notes entitled
                          to conversion in respect of the Shareholder Loan of
                          which this Note evidences a part, as determined
                          immediately after conversion

                          Loan of which this Note evidences a part, as 
                          determined immediately prior to conversion

         Holders'     =   Aggregate ownership of Stock of the Company,  
         %age             expressed as a percentage, by Holders of Convertible
         ownership        Subordinated Promissory Notes entitled to conversion

                          evidences a part, as determined immediately prior to 
                          conversion

         ownership
         
         Change        =  The percentage obtained by (1) dividing the
                          aggregate principal amount of the Shareholder Loan 
                          that is subject to conversion (and of which this Note
                          evidences a part) by $1,000,000, and (2) multiplying

                          of such Holder's ratable share of the aggregate

Existing   =    The aggregate number of shares of Stock (Common and Preferred)
Shares          owned by all Holders of Convertible Subordinated Promissory
                Notes entitled to conversion in respect of the Shareholder 
                Loan of which this Note evidences a part, as determined 
                immediately prior to conversion 


Loan %age =     The result, expressed as a percentage, obtained by dividing the 
                principal amount of this Note entitled to conversion by the 
                aggregate amount of the Shareholder Loan entitled to conversion
                as part of the same conversion event


By way of example, if the number of Existing Shares owned by all Holders of
Convertible Subordinated Promissory Notes is 4,900,000 and the Other Shares
owned or controlled by all Shareholders that are not Holders of Convertible
Subordinated Promissory Notes is 5,100,000, and if the aggregate principal
amount of the Shareholder Loan that is subject to conversion is $13,000,000:

then  Total Shares = 5,100,000 x (49.0 + 18.2) / (51.0 - 18.2)
                     = 5,100,000 x 67.2 / 32.8
                     = 10,448,780 shares

After such conversion, Total shares outstanding and held by Holders of
Convertible Subordinated Promissory Notes, as determined immediately after
conversion, would represent

         10,448,780 / (10,448,780 + 5,100,000) = 0.672 or 67.2% of all 
outstanding shares in the corporation.

Group/Credit Finance, Inc., and Rolling Profit Holdings Limited, dated April 16,
1996, to payment in full of the Superior Debt (as defined therein).

            4.1. Subrogation. Notwithstanding the subordination provided for in 
the foregoing provisions of this Section 4, the Holder's right to receive shares
of Series A Preferred Stock of the Company ("Series A Preferred Stock") (and any
cash in lieu of fractional shares) upon conversion of this Note shall be the
Holder's sole remedy following the occurrence of an Event of Default and neither
such right of conversion nor any shares issuable or issued upon exercise of such
right by the Holder shall be exercisable by or payable to or receivable by the
holder of any Senior Indebtedness.

            4.2. Undertaking.  By its acceptance of this Note, the Holder agrees

to time by the Company

                                       -3-

<PAGE>   4



on its own behalf or on behalf of the holder of any Senior Indebtedness to give
effect to the foregoing provisions of this Section 4.

         5. Prepayment. This Note may be prepaid in whole or in part, without
penalty, at any time prior to its conversion in accordance with Section 6
hereof.

         6. Conversion.

            6.1. Automatic Conversion. At the close of business on the Maturity
Date the entire unpaid principal amount of this Note and any accrued and unpaid
interest thereon shall be automatically converted into shares of Series A
Preferred Stock. The conversion shall be effected in accordance with the formula
attached hereto as Annex 1.

            6.2. Conversion Procedure.

                  6.2.1. Notice of Conversion Pursuant to Section 6.1. If this
            Note is automatically converted, written notice in the form attached
            hereto as Annex 2 shall be delivered to the Holder of this Note at
            the address last shown on the records of the Company for the Holder
            or given by the Holder to the Company for the purpose of notice or,
            if no such address appears or has been given, at the place where the
            principal executive office or residence of the Holder is located,
            notifying the Holder of the conversion to be effected, specifying
            the principal amount of this Note to be converted and the date on
            which such conversion will occur (or has occurred), and calling upon
            the Holder to surrender to the Company, in the manner and at the
            place designated, this Note. As promptly as practicable after the
            automatic conversion of this Note, the Company at its expense will
            issue and deliver to the Holder of this Note a certificate or
            certificates for the number of full shares of Series A Preferred
            Stock issuable upon such conversion.

                  6.2.2. Mechanics and Effect of Conversion. No fractional 
            shares of Series A Preferred Stock shall be issued upon conversion
            of this Note. In lieu of the Company issuing any fractional shares
            to the Holder upon the conversion of this Note, the Company shall
            pay to the Holder the amount of outstanding principal that is not so
            converted, such payment to be in the form of a check payable to the
            Holder. Upon conversion of this Note and payment of any cash in lieu
            of fractional shares, the Company shall be forever released from all
            its obligations and liabilities under this Note.

            6.3. No Impairment. The Company will not avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in carrying
out all the provisions of this Section 6 and in taking all such action as may be
necessary or appropriate in order to protect the conversion rights of the Holder
of this Note against impairment.

<PAGE>   5



         7.  Reservation of Stock Issuable Upon Conversion. The Company shall at
all times reserve and keep available out of its authorized but unissued shares
of Series A Preferred Stock solely for the purpose of effecting the conversion
of this Note such number of shares of Series A Preferred Stock (and shares of
Common Stock of the Company ("Common Stock") for issuance on conversion of such
Series A Preferred Stock) as shall from time to time be sufficient to effect the
conversion of this Note; and if at any time the number of authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) shall not be sufficient
to effect the conversion of the entire outstanding principal amount of this
Note, in addition to such other remedies as shall be available to the Holder,
the Company will use all reasonable efforts to take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) to the number of shares
that is sufficient for such purposes.

         8.  Assignment. Subject to the restrictions on transfer described in
Section 10 below, the rights and obligations of the Company and the Holder of
this Note shall be binding upon and benefit the successors, assigns, heirs,
administrators and transferees of the parties. The rights and obligations of the
Company under this Note may not be assigned by the Company without the prior
written consent of the Holder.

         9.  Waiver and Amendment. Any provision of this Note may be amended,
waived or modified only upon the written consent of the Company and the Holder;
PROVIDED, HOWEVER, that the Company hereby waives (i) presentment for payment,
protest and demand, notice of protest, demand and dishonor and nonpayment of
this Note and (ii) the defense of the statute of limitations in any action on
this Note to the extent permitted by law.

         10. Transfer of this Note or Securities Issuable on Conversion Hereof.
With respect to any offer, sale or other disposition of this Note or securities
into which this Note may be converted, the provisions of Section 7 of the
Shareholders' Agreement shall apply, mutatis mutandis, to the same extent as if
this Note and such securities were "Stock" (as defined in the Shareholders'
Agreement). Each Note thus transferred and each certificate representing the
securities thus transferred shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with the Act,
unless in the opinion of counsel for the Company such legend is not required in
order to ensure compliance with the Act. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions.

         11. Treatment of Note. To the extent permitted by generally accepted
accounting principles, the Company will treat, account and report this Note as
debt and not equity for accounting purposes and with respect to any returns
filed with federal, state or local tax authorities.

                                    evidences a part, as determined immediately

        Loan %age        =          The result, expressed as a percentage, 
                                    obtained by dividing the principal amount of
                                    this Note entitled to conversion by the

                                    conversion event

By way of example, if the number of Existing Shares owned by all Holders of
Convertible Subordinated Promissory Notes is 4,900,000 and the Other Shares
owned or controlled by all Shareholders that are not Holders of Convertible
Subordinated Promissory Notes is 5,100,000, and if the aggregate principal
amount of the Shareholder Loan that is subject to conversion is $13,000,000:

then  Total Shares = 5,100,000 x (49.0 + 18.2) / (51.0 - 18.2)
                     = 5,100,000 x 67.2 / 32.8
                     = 10,448,780 shares

After such conversion, Total shares outstanding and held by Holders of
Convertible Subordinated Promissory Notes, as determined immediately after
conversion, would represent

         10,448,780/(10,448,780 + 5,100,000) = 0.672 or 67.2% of all 
outstanding shares in the corporation.

         Warrants (as defined in the Merger Agreement), or (C) the Shareholders'
         Agreement, in each case to be performed or observed by the Company and
         such failure shall continue beyond any applicable grace period.

         4. Subordination. The indebtedness evidenced by this Note is hereby
expressly subordinated in right of payment, to the extent and in the manner set
forth in that certain Debt Subordination Agreement among the Company, The CIT

to payment in full of the Superior Debt (as defined therein).

            4.1. Subrogation. Notwithstanding the subordination provided
for in the foregoing provisions of this Section 4, the Holder's right to receive
shares of Series A Preferred Stock of the Company ("Series A Preferred Stock")
(and any cash in lieu of fractional shares) upon conversion of this Note shall
be the Holder's sole remedy following the occurrence of an Event of Default and
neither such right of conversion nor any shares issuable or issued upon exercise
of such right by the Holder shall be exercisable by or payable to or receivable
by the holder of any Senior Indebtedness.

            4.2. Undertaking.  By its acceptance of this Note, the Holder agrees
to execute and deliver such documents as may reasonably be requested from time
to time by the Company

                                       -3-

<PAGE>   4



on its own behalf or on behalf of the holder of any Senior Indebtedness to give
effect to the foregoing provisions of this Section 4.

         5. Prepayment. This Note may be prepaid in whole or in part, without
penalty, at any time prior to its conversion in accordance with Section 6
hereof.

         6. Conversion.

            6.1. Automatic Conversion. At the close of business on the Maturity
Date the entire unpaid principal amount of this Note and any accrued and unpaid
interest thereon shall be automatically converted into shares of Series A
Preferred Stock. The conversion shall be effected in accordance with the formula
attached hereto as Annex 1.

           6.2. Conversion Procedure.

                6.2.1. Notice of Conversion Pursuant to Section 6.1. If this 
           Note is automatically converted, written notice in the form attached
           hereto as Annex 2 shall be delivered to the Holder of this Note at
           the address last shown on the records of the Company for the Holder
           or given by the Holder to the Company for the purpose of notice or,
           if no such address appears or has been given, at the place where the
           principal executive office or residence of the Holder is located,
           notifying the Holder of the conversion to be effected, specifying the
           principal amount of this Note to be converted and the date on which
           such conversion will occur (or has occurred), and calling upon the
           Holder to surrender to the Company, in the manner and at the place
           designated, this Note. As promptly as practicable after the automatic
           conversion of this Note, the Company at its expense will issue and
           deliver to the Holder of this Note a certificate or certificates for
           the number of full shares of Series A Preferred Stock issuable upon
           such conversion.

                6.2.2. Mechanics and Effect of Conversion. No fractional shares
           of Series A Preferred Stock shall be issued upon conversion of this
           Note. In lieu of the Company issuing any fractional shares to the
           Holder upon the conversion of this Note, the Company shall pay to the
           Holder the amount of outstanding principal that is not so converted,
           such payment to be in the form of a check payable to the Holder. Upon
           conversion of this Note and payment of any cash in lieu of fractional
           shares, the Company shall be forever released from all its
           obligations and liabilities under this Note.

           6.3. No Impairment. The Company will not avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in carrying
out all the provisions of this Section 6 and in taking all such action as may be
necessary or appropriate in order to protect the conversion rights of the Holder
of this Note against impairment.

                                       -4-

<PAGE>   5



         7.  Reservation of Stock Issuable Upon Conversion. The Company shall at
all times reserve and keep available out of its authorized but unissued shares
of Series A Preferred Stock solely for the purpose of effecting the conversion
of this Note such number of shares of Series A Preferred Stock (and shares of
Common Stock of the Company ("Common Stock") for issuance on conversion of such
Series A Preferred Stock) as shall from time to time be sufficient to effect the
conversion of this Note; and if at any time the number of authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) shall not be sufficient
to effect the conversion of the entire outstanding principal amount of this
Note, in addition to such other remedies as shall be available to the Holder,
the Company will use all reasonable efforts to take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) to the number of shares
that is sufficient for such purposes.

         8.  Assignment. Subject to the restrictions on transfer described in
Section 10 below, the rights and obligations of the Company and the Holder of
this Note shall be binding upon and benefit the successors, assigns, heirs,
administrators and transferees of the parties. The rights and obligations of the
Company under this Note may not be assigned by the Company without the prior
written consent of the Holder.

         9.  Waiver and Amendment. Any provision of this Note may be amended,
waived or modified only upon the written consent of the Company and the Holder;
PROVIDED, HOWEVER, that the Company hereby waives (i) presentment for payment,
protest and demand, notice of protest, demand and dishonor and nonpayment of
this Note and (ii) the defense of the statute of limitations in any action on
this Note to the extent permitted by law.

         10. Transfer of this Note or Securities Issuable on Conversion Hereof.
With respect to any offer, sale or other disposition of this Note or securities
into which this Note may be converted, the provisions of Section 7 of the
Shareholders' Agreement shall apply, mutatis mutandis, to the same extent as if
this Note and such securities were "Stock" (as defined in the Shareholders'
Agreement). Each Note thus transferred and each certificate representing the
securities thus transferred shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with the Act,
unless in the opinion of counsel for the Company such legend is not required in
order to ensure compliance with the Act. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions.

         11. Treatment of Note. To the extent permitted by generally accepted
accounting principles, the Company will treat, account and report this Note as
debt and not equity for accounting purposes and with respect to any returns
filed with federal, state or local tax authorities.

         12. Notices. All notices, requests and other communications that any

         New Shares    =   (Total Shares  -  Existing Shares)  x  Loan %age


         where:

         Total Shares  =   Total number of shares outstanding and held by 
                           Holders of Convertible Subordinated Promissory Notes
                           entitled to conversion in respect of the Shareholder
                           Loan of which this Note evidences a part, as
                           determined immediately after conversion

         Other         =   Aggregate number of shares of Stock (Common and 
                           Preferred)

         Shares            owned or controlled by all shareholders that
                           are not Holders of Convertible Subordinated
                           Promissory Notes entitled to conversion in
                           respect of the Shareholder Loan of which
                           this Note evidences a part, as determined
                           immediately prior to conversion

         Holders'      =   Aggregate ownership of Stock of the Company,
         %age              expressed as a percentage, by Holders of Convertible
         ownership         Subordinated Promissory Notes entitled to conversion
                           in respect of the Shareholder Loan of which this Note
                           evidences a part, as determined immediately prior to
                           conversion

         Others' %age  =   100% MINUS Holders' %age ownership
         ownership

         Change        =   The percentage obtained by (1) dividing the aggregate
                           principal amount of the Shareholder Loan that is
                           subject to conversion (and of which this Note
                           evidences a part) by $1,000,000, and (2) multiplying
                           the result by 1.4.

         New Shares    =   The number of shares of Series A Preferred Stock

                           of such Holder's ratable share of the aggregate
                           Shareholder Loan amount converted (and used to

<TABLE>
         <S>           <C> <C>
         Existing      =   The aggregate number of shares of Stock (Common and
         Shares            Preferred) owned by all Holders of Convertible
                           Subordinated Promissory Notes entitled to conversion
                           in respect of the Shareholder Loan of which this Note
                           evidences a part, as determined immediately prior to
                           conversion

         Loan %age     =   The result, expressed as a percentage, obtained by
                           dividing the principal amount of this Note entitled
                           to conversion by the aggregate amount of the
                           Shareholder Loan entitled to conversion as part of
                           the same conversion event
</TABLE>



By way of example, if the number of Existing Shares owned by all Holders of
Convertible Subordinated Promissory Notes is 4,900,000 and the Other Shares
owned or controlled by all Shareholders that are not Holders of Convertible
Subordinated Promissory Notes is 5,100,000, and if the aggregate principal
amount of the Shareholder Loan that is subject to conversion is $13,000,000:

then Total Shares  = 5,100,000 x (49.0 + 18.2) / (51.0 - 18.2)
                     = 5,100,000 x 67.2 / 32.8
                     = 10,448,780 shares

After such conversion, Total shares outstanding and held by Holders of
Convertible Subordinated Promissory Notes, as determined immediately after
conversion, would represent

         10,448,780 / (10,448,780 + 5,100,000) = 0.672 or 67.2% of all
outstanding shares in the corporation.

         4.  Subordination. The indebtedness evidenced by this Note is hereby
expressly subordinated in right of payment, to the extent and in the manner set
forth in that certain Debt Subordination Agreement among the Company, The CIT

1996, to payment in full of the Superior Debt (as defined therein).

             4.1.   Subrogation. Notwithstanding the subordination provided for
in the foregoing provisions of this Section 4, the Holder's right to receive
shares of Series A Preferred Stock of the Company ("Series A Preferred Stock")
(and any cash in lieu of fractional shares) upon conversion of this Note shall
be the Holder's sole remedy following the occurrence of an Event of Default and
neither such right of conversion nor any shares issuable or issued upon exercise
of such right by the Holder shall be exercisable by or payable to or receivable
by the holder of any Senior Indebtedness.

             4.2.   Undertaking.  By its acceptance of this Note, the Holder

                                       -3-


<PAGE>   4



on its own behalf or on behalf of the holder of any Senior Indebtedness to give
effect to the foregoing provisions of this Section 4.

         5.     Prepayment.  This Note may be prepaid in whole or in part,
without penalty, at any time prior to its conversion in accordance with Section
6 hereof.

         6.     Conversion.

             6.1.   Automatic Conversion. At the close of business on the
Maturity Date the entire unpaid principal amount of this Note and any accrued
and unpaid interest thereon shall be automatically converted into shares of
Series A Preferred Stock. The conversion shall be effected in accordance with
the formula attached hereto as Annex 1.

             6.2.   Conversion Procedure.

                    6.2.1. Notice of Conversion Pursuant to Section 6.1. If this
             Note is automatically converted, written notice in the form
             attached hereto as Annex 2 shall be delivered to the Holder of this
             Note at the address last shown on the records of the Company for
             the Holder or given by the Holder to the Company for the purpose of
             notice or, if no such address appears or has been given, at the
             place where the principal executive office or residence of the
             Holder is located, notifying the Holder of the conversion to be
             effected, specifying the principal amount of this Note to be
             converted and the date on which such conversion will occur (or has
             occurred), and calling upon the Holder to surrender to the Company,
             in the manner and at the place designated, this Note. As promptly
             as practicable after the automatic conversion of this Note, the
             Company at its expense will issue and deliver to the Holder of this
             Note a certificate or certificates for the number of full shares of
             Series A Preferred Stock issuable upon such conversion.

                    6.2.2. Mechanics and Effect of Conversion. No fractional
             shares of Series A Preferred Stock shall be issued upon conversion
             of this Note. In lieu of the Company issuing any fractional shares
             to the Holder upon the conversion of this Note, the Company shall
             pay to the Holder the amount of outstanding principal that is not
             so converted, such payment to be in the form of a check payable to
             the Holder. Upon conversion of this Note and payment of any cash in
             lieu of fractional shares, the Company shall be forever released
             from all its obligations and liabilities under this Note.

             6.3.   No Impairment. The Company will not avoid or seek to avoid
the observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in carrying
out all the provisions of this Section 6 and in taking all such action as may be
necessary or appropriate in order to protect the conversion rights of the Holder
of this Note against impairment.

                                       -4-

         7.  Reservation of Stock Issuable Upon Conversion. The Company shall at
all times reserve and keep available out of its authorized but unissued shares
of Series A Preferred Stock solely for the purpose of effecting the conversion
of this Note such number of shares of Series A Preferred Stock (and shares of
Common Stock of the Company ("Common Stock") for issuance on conversion of such
Series A Preferred Stock) as shall from time to time be sufficient to effect the
conversion of this Note; and if at any time the number of authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) shall not be sufficient
to effect the conversion of the entire outstanding principal amount of this
Note, in addition to such other remedies as shall be available to the Holder,
the Company will use all reasonable efforts to take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) to the number of shares
that is sufficient for such purposes.

         8.  Assignment. Subject to the restrictions on transfer described in
Section 10 below, the rights and obligations of the Company and the Holder of
this Note shall be binding upon and benefit the successors, assigns, heirs,
administrators and transferees of the parties. The rights and obligations of the
Company under this Note may not be assigned by the Company without the prior
written consent of the Holder.

         9.  Waiver and Amendment. Any provision of this Note may be amended,
waived or modified only upon the written consent of the Company and the Holder;
PROVIDED, HOWEVER, that the Company hereby waives (i) presentment for payment,
protest and demand, notice of protest, demand and dishonor and nonpayment of
this Note and (ii) the defense of the statute of limitations in any action on
this Note to the extent permitted by law.

         10. Transfer of this Note or Securities Issuable on Conversion Hereof.
With respect to any offer, sale or other disposition of this Note or securities
into which this Note may be converted, the provisions of Section 7 of the
Shareholders' Agreement shall apply, mutatis mutandis, to the same extent as if
this Note and such securities were "Stock" (as defined in the Shareholders'
Agreement). Each Note thus transferred and each certificate representing the
securities thus transferred shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with the Act,
unless in the opinion of counsel for the Company such legend is not required in
order to ensure compliance with the Act. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions.

         11. Treatment of Note. To the extent permitted by generally accepted
accounting principles, the Company will treat, account and report this Note as
debt and not equity for accounting purposes and with respect to any returns
filed with federal, state or local tax authorities.

         12. Notices.  All notices, requests and other communications that any
party is required or elects to give hereunder shall be in writing and shall be

         Total Shares      =        Total number of shares outstanding and held by Holders of Convertible Subordinated Promissory
                                    Notes entitled to conversion in respect of the Shareholder Loan of which this Note evidences a

                                    evidences a part, as determined immediately prior to conversion

         Holders'          =        Aggregate ownership of Stock of the Company, expressed as a percentage, by Holders of

                                    prior to conversion

Loan %age            =              The result, expressed as a percentage, 
                                    obtained by dividing the principal amount

                                    conversion event
</TABLE>

By way of example, if the number of Existing Shares owned by all Holders of
Convertible Subordinated Promissory Notes is 4,900,000 and the Other Shares
owned or controlled by all Shareholders that are not Holders of Convertible
Subordinated Promissory Notes is 5,100,000, and if the aggregate principal
amount of the Shareholder Loan that is subject to conversion is $13,000,000:

then  Total Shares = 5,100,000 x (49.0 + 18.2) / (51.0 - 18.2)
                   = 5,100,000 x 67.2 / 32.8
                   = 10,448,780 shares

After such conversion, Total shares outstanding and held by Holders of
Convertible Subordinated Promissory Notes, as determined immediately after
conversion, would represent

         10,448,780 / (10,448,780 + 5,100,000) = 0.672 or 67.2% of all 
outstanding shares in the corporation.

            of this Note. In lieu of the Company issuing any fractional shares
            to the Holder upon the conversion of this Note, the Company shall
            pay to the Holder the amount of outstanding principal that is not so
            converted, such payment to be in the form of a check payable to the
            Holder. Upon conversion of this Note and payment of any cash in lieu
            of fractional shares, the Company shall be forever released from all
            its obligations and liabilities under this Note.

            6.3. No Impairment. The Company will not avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in carrying
out all the provisions of this Section 6 and in taking all such action as may be
necessary or appropriate in order to protect the conversion rights of the Holder
of this Note against impairment.

         7.  Reservation of Stock Issuable Upon Conversion. The Company shall at
all times reserve and keep available out of its authorized but unissued shares
of Series A Preferred Stock solely for the purpose of effecting the conversion
of this Note such number of shares of Series A Preferred Stock (and shares of
Common Stock of the Company ("Common Stock") for issuance on conversion of such
Series A Preferred Stock) as shall from time to time be sufficient to effect the
conversion of this Note; and if at any time the number of authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) shall not be sufficient
to effect the conversion of the entire outstanding principal amount of this
Note, in addition to such other remedies as shall be available to the Holder,
the Company will use all reasonable efforts to take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but
unissued shares of Series A Preferred Stock (and shares of Common Stock for
issuance on conversion of such Series A Preferred Stock) to the number of shares
that is sufficient for such purposes.

         8.  Assignment. Subject to the restrictions on transfer described in
Section 10 below, the rights and obligations of the Company and the Holder of
this Note shall be binding upon and benefit the successors, assigns, heirs,
administrators and transferees of the parties. The rights and obligations of the
Company under this Note may not be assigned by the Company without the prior
written consent of the Holder.

         9.  Waiver and Amendment. Any provision of this Note may be amended,
waived or modified only upon the written consent of the Company and the Holder;

protest and demand, notice of protest, demand and dishonor and nonpayment of
this Note and (ii) the defense of the statute of limitations in any action on
this Note to the extent permitted by law.

         10. Transfer of this Note or Securities Issuable on Conversion Hereof.
With respect to any offer, sale or other disposition of this Note or securities
into which this Note may be converted, the provisions of Section 7 of the
Shareholders' Agreement shall apply, mutatis mutandis, to the same extent as if
this Note and such securities were "Stock" (as defined in the Shareholders'
Agreement). Each Note thus transferred and each certificate representing the
securities thus transferred shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with the Act,
unless in the opinion of counsel for the Company such legend is not required in
order to ensure compliance with the Act. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions.

         11. Treatment of Note. To the extent permitted by generally accepted

  New Shares        =      (Total Shares  -  Existing Shares)  x  Loan %age


  where:

  Total Shares      =      Total number of shares outstanding and held by 
                           Holders of Convertible Subordinated Promissory Notes
                           entitled to conversion in respect of the Shareholder
                           Loan of which this Note evidences a part, as
                           determined immediately after conversion

  Other             =      Aggregate number of shares of Stock (Common and
                           Preferred)

  Shares                   owned or controlled by all shareholders that are not 
                           Holders of Convertible Subordinated Promissory Notes
                           entitled to conversion in respect of the Shareholder
                           Loan of which this Note evidences a part, as
                           determined immediately prior to conversion

  Holders'          =      Aggregate ownership of Stock of the Company, 
  %age                     expressed as a percentage, by Holders of Convertible
  ownership                Subordinated Promissory Notes entitled to conversion
                           in respect of the Shareholder Loan of which this Note
                           evidences a part, as determined immediately prior to
                           conversion

  Others' %age      =      100% MINUS Holders' %age ownership
  ownership

  Change            =      The percentage obtained by (1) dividing the 
                           aggregate  principal amount of the Shareholder Loan
                           that is subject to   conversion (and of which this
                           Note evidences a part) by $1,000,000, and (2) 
                           multiplying the result by 1.4.

                           of such Holder's ratable share of the aggregate
                           Shareholder Loan amount converted (and used to

<TABLE>
  <S>               <C>    <C>
  Existing          =      The aggregate number of shares of Stock (Common and
  Shares                   Preferred) owned by all Holders of Convertible
                           Subordinated Promissory Notes entitled to conversion
                           in respect of the Shareholder Loan of which this Note
                           evidences a part, as determined immediately prior to
                           conversion

 Loan %age          =      The result, expressed as a percentage, obtained by 
                           dividing the principal amount of this Note entitled
                           to conversion by the aggregate amount of the
                           Shareholder Loan entitled to conversion as part of
                           the same conversion event
</TABLE>



By way of example, if the number of Existing Shares owned by all Holders of
Convertible Subordinated Promissory Notes is 4,900,000 and the Other Shares
owned or controlled by all Shareholders that are not Holders of Convertible
Subordinated Promissory Notes is 5,100,000, and if the aggregate principal
amount of the Shareholder Loan that is subject to conversion is $13,000,000:

then  Total Shares = 5,100,000 x (49.0 + 18.2) / (51.0 - 18.2)
                     = 5,100,000 x 67.2 / 32.8
                     = 10,448,780 shares

After such conversion, Total shares outstanding and held by Holders of
Convertible Subordinated Promissory Notes, as determined immediately after
conversion, would represent

         10,448,780 / (10,448,780 + 5,100,000) = 0.672 or 67.2% of all
outstanding shares in the corporation.

                   4.  ADMINISTRATION. This Plan shall be administered by the
Board, whose construction and interpretation of the Plan's terms and provisions
shall be final and conclusive. The Board shall have authority, subject to the
express provisions of the Plan, to construe the Plan, any Board Warrant
agreement and any related agreements, to prescribe, amend and rescind rules and
regulations relating to the Plan, to determine the terms and provisions of a
Board Warrant agreement and related agreements, and to make all other
determinations in the judgment of the Board necessary or desirable for the
administration of the Plan. The Board may correct any defect or supply any
omission or reconcile any inconsistency in the Plan, in any Board Warrant
agreement, or in any related agreement in the manner and to the extent it shall
deem expedient to carry the Plan into effect, and it shall be the sole and final
judge of such expediency. No director shall be liable for any action or
determination made in good faith.

                   5.  ELIGIBLE RECIPIENTS. Board Warrants shall be issued by
the Secretary of the Company acting on behalf of the Company to members of the
Board of Directors of the Company on the date of the first meeting of the Board
following the Merger without the need

for any further action on the part of the Board and shall be granted equally to
the Board members (considered as a unit) appointed by (a) the Principal
Shareholder and (b) Rinzai in any proportion with respect to the directors
appointed by such shareholders that the Secretary is instructed to issue the
Board Warrants by such shareholders, respectively; provided, however, that in
each case the Board Warrants issued to each such unit shall be exercisable in
respect of an aggregate of 200,000 shares of Common Stock. Additional Board
Warrants may be issued from time to time to members of the Board as determined
by the Board; provided, however, that the total amount of Board Warrants issued
shall not exceed the Maximum Amount.

                   6.  DURATION OF THE PLAN. This Plan shall terminate ten (10)
years from the effective date hereof, unless terminated earlier pursuant to
Section 3 hereafter, and no Board Warrants may be granted or made thereafter.

                   7.  TERMS AND CONDITIONS OF BOARD WARRANTS. Board Warrants
granted under this Plan shall be evidenced by a Board Warrant, a form of which
is attached hereto as Exhibit "A", the terms and conditions of which are hereby
incorporated herein by this reference.

                   8.  TERMINATION OR AMENDMENT OF PLAN. The Board may at any
time terminate the Plan or make such changes in or additions to the Plan as it
deems advisable without further action on the part of the shareholders of the
Company, provided that no such termination or amendment shall adversely affect
or impair any then outstanding Board Warrant without the consent of the holder
thereof.

             (e)  "Initial Public Offering" means the closing of a firm
commitment underwritten public offering pursuant to an effective registration
statement under the Securities Act covering the offer and sale of the Company's
Common Stock.

             (f)  "Market Price" means the fair market value of one share
determined as follows: (i) where there exists a public market for the Company's
Common Stock at the time of such exercise, the fair market value per share shall
be the average of the closing bid and asked prices of the Common Stock quoted in
the Over-The-Counter Market Summary or the last reported sale price of the
Common Stock or the closing price quoted on the NASDAQ National Market System or
on any exchange on which the Common Stock is listed, whichever is applicable, as
published in The Wall Street Journal for the five (5) trading days (or such
fewer number of trading days as the Company's Common Stock may have been
publicly traded) ending on the trading day prior to the date of determination of
fair market value and (ii) if at any time the Common Stock is not listed on any
domestic exchange or quoted in the NASDAQ System or the domestic
over-the-counter market, the higher of (A) the book value thereof, as determined
by any firm of independent public accountants of recognized standing selected by
the Board of Directors, as at the last day as of which such determination shall
have been made, or (B) the fair value thereof determined in good faith by the
Board of Directors as of the date which is within 15 days of the date as of
which the determination is to be made (in determining the fair value thereof,
the Board of Directors shall consider stock market valuations and price to
earnings ratios of comparable companies in similar industries). Notwithstanding
the foregoing, in the event the Warrant is exercised in connection with the
Initial Public Offering, the fair market value per share shall be the per share
price at which registered shares are sold to the public in the Initial Public
Offering. If the holder shall purchase such shares in conjunction with the
closing of any Significant Transaction, then the fair market value per share
shall mean the value received by the holders of the Company's Common Stock
pursuant to such Significant Transaction for each share of Common Stock, subject
to the closing of such Significant Transaction.

             (g)  "Securities Act" means the Securities Act of 1933, as amended.

             (h)  "Significant Transaction" means the closing of a merger,
consolidation or reorganization of the Company with or into any other
corporation or corporations in which the Company is not the surviving entity
(other than a mere reincorporation transaction), a sale of all or substantially
all of the assets of the Company or a transaction or series of related
transactions in which the Company issues shares representing more than 50% of
the voting power of the Company, immediately after giving effect to such
transaction, to a person or persons who were not Shareholders (as defined in the
Shareholders' Agreement) immediately prior to such transaction.

             (i)  "Warrant Exercise Price" shall initially be US$0.714 per share
and shall be adjusted and readjusted from time to time as provided in this
Warrant.

             (j)  Other Definitional Provisions.
                  (i)  Except as otherwise specified herein, all references
         herein (A) to any person other than the Company, shall be deemed to
         include such person's successors and

         permitted assigns, (B) to the Company shall be deemed to include the
         Company's successors and (C) to any applicable law defined or referred
         to herein, shall be deemed references to such applicable law as the
         same may have been or may be amended or supplemented from time to time.

                 (ii)  When used in this Warrant, the words "herein," "hereof,"
         and "hereunder," and words of similar import, shall refer to this
         Warrant as a whole and not to any provision of this Warrant, and the
         words "Section," "Schedule," and "Exhibit" shall refer to Sections of,
         and Schedules and Exhibits to, this Warrant unless otherwise specified.

                (iii)  Whenever the context so requires the neuter gender
         includes the masculine or feminine, and the singular number includes
         the plural, and vice versa.

                 (iv)  Any capitalized term not otherwise defined in this
         Warrant shall have the meaning ascribed to such term in that certain
         Shareholders' Agreement dated as of April 16, 1996 (the "Shareholders'
         Agreement"), by and among the Company, Dennis C. Hayes and the
         Shareholders.

         2.       Exercise of Warrant.

                  (a)  Subject to the terms and conditions hereof, this Warrant
may be exercised in whole or in part, at any time during normal business hours
on or after the Exercise Date and prior to 5:00 p.m., Atlanta, Georgia time, on
the Expiration Date. The rights represented by this Warrant may be exercised by
the holder hereof then registered on the books of the Company, in whole or from
time to time in part (except that this Warrant shall not be exercisable as to a
fractional share), by (i) delivery of a written notice, in the form of the
Subscription Notice attached as Exhibit A hereto, of such holder's election to
exercise this Warrant, which notice shall specify the number of Warrant Shares
to be purchased, (ii) payment to the Company of an amount equal to the Warrant
Exercise Price multiplied by the number of Warrant Shares as to which the
Warrant is being exercised (plus any applicable issue or transfer taxes) in
cash, by wire transfer or by certified or official bank check, for the number of
Warrant Shares as to which this Warrant shall have been exercised, and (iii) the
surrender of this Warrant, properly endorsed, at the principal office of the
Company in Atlanta, Georgia (or at such other agency or office of the Company as
the Company may designate by notice to the Holder); provided, that if such
Warrant Shares are to be issued in any name other than that of the Holder, such
issuance shall be deemed a transfer and the provisions of Section 14 shall be
applicable. In the event of any exercise of the rights represented by this
Warrant, a certificate or certificates for the Warrant Shares so purchased,
registered in the name of, or as directed by, the Holder, shall be delivered to,
or as directed by the Holder within a reasonable time, not exceeding 15 days (if
the Company's Common Stock is not then publicly traded) or five (5) business
days (if the Company's Common Stock is then publicly traded), after such rights
shall have been so exercised.

                  (b)  Unless the rights represented by this Warrant shall have
expired or have been fully exercised, the Company shall issue, within such 15
day or 5 business day period, as applicable,

                                       -3-


<PAGE>   4



a new Warrant identical in all respects to the Warrant exercised except (x) such
new Warrant shall represent rights to purchase the number of Warrant Shares
purchasable immediately prior to such exercise under the warrant exercised, less
the number of Warrant Shares with respect to which such original Warrant was
exercised, and (y) the Warrant Exercise Price thereof shall be the Warrant
Exercise Price of the Warrant exercised. The person in whose name any
certificate for Warrant Shares is issued upon exercise of this Warrant shall for
all purposes be deemed to have become the holder of record of such Warrant
Shares immediately prior to the close of business on the date on which the
Warrant was surrendered and payment of the amount due in respect of such
exercise and any applicable taxes was made, irrespective of the date of delivery
of such share certificate, except that, if the date of such surrender and
payment is a date when the stock transfer books of the Company are properly
closed, such person shall be deemed to have become the holder of such Warrant
Shares at the opening of business on the next succeeding date on which the stock
transfer books are open.

                  (c)  In lieu of the Holder exercising this Warrant (or any
portion hereof) for cash, it may, in connection with such exercise, elect to
satisfy the Warrant Exercise Price by exchanging solely (x) this Warrant (or
such portion hereof) for (y) that number of Warrant Shares equal to the product
of (i) the number of shares of Common Stock issuable upon such exercise of the
Warrant (or, if only a portion of this Warrant is being exercised, issuable upon
the exercise of such portion) for cash multiplied by (ii) a fraction, (A) the
numerator of which is the Market Price per share of the Common Stock at the time
of such exercise minus the Warrant Exercise Price per share of the Common Stock
at the time of such exercise, and (B) the denominator of which is the Market
Price per share of the Common Stock at the time of such exercise, such number of
shares so issuable upon such exercise to be rounded up or down to the nearest
whole number of Warrant Shares.

         3.       Covenants as to Common Stock.

                  (a)  The Company covenants and agrees that all Warrant Shares
which may be issued upon the exercise of the rights represented by this Warrant
will, upon issuance, be validly issued, fully paid and nonassessable. The
Company further covenants and agrees that during the period within which the
rights represented by this Warrant may be exercised, the Company will at all
times have authorized and reserved a sufficient number of shares of Common Stock
to provide for the exercise of the rights then represented by this Warrant and
that the par value of said shares will at all times be less than or equal to the
applicable Warrant Exercise Price.

                  (b)  If any shares of Common Stock reserved or to be reserved
to provide for the exercise of the rights then represented by this Warrant
require registration with or approval of any governmental authority under any
federal or state law before such shares may be validly issued to the Holder,
then the Company covenants that it will in good faith and as expeditiously as
possible endeavor to secure such registration or approval, as the case may be.

         4.       Adjustment of Warrant Exercise Price Upon Stock Splits,
Dividends, Distributions and Combinations; and Adjustment of Number of Shares.

                  (a)  In case the Company shall at any time subdivide its
outstanding shares of Common Stock into a greater number of shares or issue a
stock dividend (including any distribution of stock without consideration) or
make a distribution with respect to outstanding shares of Common Stock or
convertible securities payable in Common Stock or in convertible securities, the
Warrant Exercise Price in effect immediately prior to such subdivision or stock
dividend or distribution shall be proportionately reduced and conversely, in
case the outstanding shares of Common Stock of the Company shall be combined
into a smaller number of shares, the Warrant Exercise Price in effect
immediately prior to such combination shall be proportionately increased in each
case by multiplying the then effective Warrant Exercise Price by a fraction, the
numerator of which shall be the total number of shares of Common Stock
outstanding immediately prior to such subdivision, stock dividend, distribution
or combination (determined on a fully diluted basis), and the denominator of
which shall be the total number of shares of Common Stock, immediately after
such subdivision, stock dividend, distribution or combination (determined on a
fully diluted basis), and the product so obtained shall be thereafter the
Warrant Exercise Price.

                  (b)  Upon each adjustment of the Warrant Exercise Price as
provided above in this Section 4, the Holder shall thereafter be entitled to
purchase, at the Warrant Exercise Price resulting from such adjustment, the
number of shares (calculated to the nearest tenth of a share) obtained by
multiplying the Warrant Exercise Price in effect immediately prior to such
adjustment by the number of shares purchasable pursuant hereto immediately prior
to such adjustment and dividing the product thereof by the Warrant Exercise
Price immediately after such adjustment.

         5.       Adjustment of Warrant Exercise Price Upon Certain Issuances
or Sales of Common Stock. Whenever the Company shall issue, sell or otherwise
distribute any shares of its Common Stock (except for the Preferred Shares
issuable upon the conversion of the Convertible Promissory Notes, options issued
to officers and employees of the Company pursuant to plans adopted by the Board
of Directors of the Company, and shares of Common Stock issuable upon the
exercise of such options, shares of Common Stock issuable upon the conversion of
the Preferred Shares or the Warrants and except as provided in Section 6 of this
Warrant) and the amount of consideration per share is less than the Warrant
Exercise Price in effect immediately prior to the time of such issuance or sale,
then, forthwith upon such issue or sale, and thereafter successively upon each
such issue, the Warrant Exercise Price shall be reduced to the amount
(calculated to the nearest one hundredth of a cent) determined by dividing (i)
an amount equal to the sum of (x) the number of shares of Common Stock
outstanding immediately prior to such issue or sale multiplied by the then
existing Warrant Exercise Price, and (y) the consideration, if any, received by
the Company upon such issue or sale, by (ii) the total number of shares of
Common Stock outstanding immediately after such issue or sale.

                 Whenever the Warrant Exercise Price is adjusted under this
Section 5, the Holder shall thereafter be entitled to purchase at the new
Warrant Exercise Price the number of shares of Common Stock obtained by
multiplying the Warrant Exercise Price in effect immediately prior to such
adjustment by the number of shares of Common Stock purchasable pursuant hereto
immediately prior to such adjustment and dividing the product thereof by the new
Warrant Exercise Price.

                 For the purposes of this Section 5, the following clauses (i)
to (vii), inclusive, shall also be applicable:

                           (i)  in case at any time the Company shall in any
         manner grant any rights to subscribe for, or any rights or options to
         purchase, any Common Stock or any Convertible Securities, whether or
         not such rights or options or the rights to convert or exchange any
         such Convertible Securities are immediately exercisable, and the
         purchase price per share for which Common Stock is issuable upon the
         exercise of such rights or options or upon conversion or exchange of
         such Convertible Securities (determined by dividing (x) the total
         amount, if any, received or receivable by the Company as consideration
         for the granting of all such rights or options, plus the minimum
         aggregate amount of additional consideration payable to the Company
         upon the exercise of all such rights or options, plus, in the case of
         such Convertible Securities, if any, payable upon, the conversion or
         exchange thereof, by (y) the maximum aggregate number of shares of
         Common Stock issuable upon the exercise of such rights or options or
         upon the conversion or exchange of all such Convertible Securities
         issuable upon the exercise of such rights or options) shall be less
         than or the Warrant Exercise Price in effect immediately prior to the
         time of the granting of such rights or options, then the maximum
         aggregate number of shares of Common Stock issuable upon the exercise
         of such rights or options or upon conversion or exchange of the total
         maximum amount of such Convertible Securities issuable upon the
         exercise of such rights or options shall (as of the date of granting of
         such rights or options) be deemed to be outstanding and to have been
         issued for such price per share. No further adjustments of the Warrant
         Exercise Price shall be made upon the actual issue of such Common Stock
         upon conversion or exchange of such Convertible Securities, except as
         otherwise provided in clause (iii) below;

                          (ii)  in case at any time the Company shall in any
         manner issue or sell any Convertible Securities, whether or not the
         rights to exchange or convert thereunder are immediately exercisable,
         and the purchase price per share for which Common Stock is issuable
         upon such conversion or exchange (determined by dividing (x) the total
         amount received or receivable by the Company as consideration for the
         issue or sale of all such Convertible Securities, plus the minimum
         aggregate amount of additional consideration, if any, payable to the
         Company upon the conversion or exchange thereof, by (y) the maximum
         aggregate number of shares of Common Stock issuable upon the conversion
         or exchange of all such Convertible Securities) shall be less than the
         Warrant Exercise Price in effect immediately prior to the time of such
         issue or sale, then the maximum aggregate number of shares of Common
         Stock issuable upon conversion or exchange of all such Convertible
         Securities shall (as of the date of the issue or sale of such
         Convertible Securities) be deemed outstanding and to have been issued
         for such price per share, provided that, except as otherwise specified
         in clause (iii) below, (a) no further adjustments of the Warrant
         Exercise Price shall be made upon the actual issue of such Common Stock
         upon conversion or exchange of such Convertible Securities, and (b) if
         any such issue or sale of such Convertible Securities is made upon
         exercise of any rights to subscribe for or to purchase or upon exercise
         of any option to purchase any such Convertible Securities for which
         adjustments of the Warrant Exercise Price have been or are to be made
         pursuant to other

                                       -6-


<PAGE>   7



         provisions of this Section 5, no further adjustment of the Warrant
         Exercise Price shall be made by reason of such issue or sale;

                         (iii)  if the purchase price or number of shares
         purchasable provided for in any right or option referred to in clause
         (i) above, or the rate at which any Convertible Securities referred to
         in clause (i) or (ii) above are convertible into or exchangeable for
         Common Stock, shall change at any time (other than under or by reason
         of provisions designed to protect against dilution for which provision
         for adjustments in the Warrant Exercise Price are provided for under
         this Warrant), the Warrant Exercise Price then in effect hereunder
         shall forthwith be readjusted to such Warrant Exercise price as would
         have obtained had the adjustments made upon the issuance of such
         rights, options or Convertible Securities been made upon the basis of
         the changed terms; and on the expiration of any such option or right
         referred to in clause (i) above or the termination of any such right to
         convert or exchange such Convertible Securities referred to in clause
         (i) or (ii) above, the Warrant Exercise Price then in effect hereunder
         shall forthwith be readjusted to such Warrant Exercise Price as would
         have obtained had the adjustments made upon the issuance of such rights
         or options or Convertible Securities been made upon the basis of the
         issuance of only the number of shares of Common Stock, if any,
         theretofore actually delivered upon the exercise of such rights or
         options or upon the conversion or exchange of such Convertible
         Securities;

                          (iv)  in case the Company shall distribute to all
         holders of its Common Stock evidences of its indebtedness or assets,
         then in each such case the Warrant Exercise Price in effect immediately
         prior to such distribution shall be adjusted so that the same shall
         equal the price determined by multiplying the Warrant Exercise Price in
         effect immediately prior to the date of such distribution by a fraction
         whose numerator shall be (i) the Market Price per share of Common Stock
         immediately prior to the effective date of distribution multiplied by
         the total number of shares of Common Stock outstanding immediately
         prior to such effective date less (ii) the then fair market value (as
         reasonably determined by the Board of Directors) of the assets or
         evidences of indebtedness so distributed and whose denominator shall be
         such Market Price per share of the Common Stock multiplied by the total
         number of shares of Common Stock outstanding immediately prior to such
         effective date. Such adjustment shall be made whenever any such
         distribution is made and shall be retroactively effective as of
         immediately after the record date for the determination of stockholders
         entitled to receive such distribution;

                           (v)  the consideration received for any shares of
         Common Stock or Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities issued or sold
         shall be deemed to be the amount received therefor, before deduction
         therefrom of any expenses incurred or any underwriting commissions or
         concessions paid or allowed in connection therewith; in case any shares
         of Common Stock or Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities shall be
         issued or sold for a consideration other than cash, the amount of the
         consideration other than cash (including any non-cash consideration
         received in

                                       -7-


<PAGE>   8



         respect of any acquisition by the Company of substantially all of the
         stock or assets of another entity) received by the Company for such
         shares shall be deemed to be the value of such consideration as
         determined reasonably and in good faith by the Board of Directors;

                          (vi)  in case the Company shall take a record of the
         holders of its Common Stock for the purpose of entitling them (x) to
         receive a dividend or other distribution, or (y) to receive rights or
         options to subscribe for Common Stock or Convertible Securities, then
         such record date shall be deemed to be the date of the issue or sale of
         the shares of Common Stock deemed to have been issued or sold upon the
         declaration of such dividend or the making of such other distribution
         or the date of the granting of such right or option of subscription or
         purchase; and

                         (vii)  the number of shares of Common Stock
         outstanding at any given time shall not include shares owned or held by
         or for the account of the Company; but the disposition of any shares so
         owned or held shall be considered an issue or sale of Common Stock for
         the purposes of this Section 5.

         6.       Reorganization, Reclassification, Etc. In case of any capital
reorganization, or of any reclassification of the capital stock of the Company
(other than a change in par value or from par value to no par value or from no
par value to par value or as a result of a split-up or combination) or in case
of the consolidation or merger of the Company with or into any other corporation
(other than a consolidation or merger in which the Company is the continuing
corporation and which does not result in the Common Stock being changed into or
exchanged for stock or other securities or property of any other person), or of
the sale of the properties and assets of the Company as, or substantially as, an
entirety to any other corporation, this Warrant shall, after such capital
reorganization, reclassification of capital stock, consolidation, merger or
sale, entitle the Holder hereof to purchase the kind and number of shares of
stock or other securities or property of the Company or of the corporation
resulting from such consolidation or surviving such merger or to which such sale
shall be made, as the case may be, to which the holder hereof would have been
entitled if he had held the Common Stock issuable upon the exercise hereof
immediately prior to such capital reorganization, reclassification of capital
stock, consolidation, merger or sale, and in any such case appropriate provision
shall be made with respect to the rights and interests of the holder of this
Warrant to the end that the provisions thereof (including without limitation
provisions for adjustment of the Warrant Exercise Price and of the number of
shares purchasable upon the exercise of this Warrant) shall thereafter be
applicable, as nearly as may be in relation to any shares of stock, securities,
or assets thereafter deliverable upon the exercise of the rights represented
hereby. The Company shall not effect any such consolidation, merger or sale,
unless prior to or simultaneously with the consummation thereof the successor
corporation (if other than the Company) resulting from such consolidation or
merger of the corporation purchasing such assets shall assume by written
instrument executed and mailed or delivered to the registered holder hereof at
the address of such holder appearing on the books of the Company, the obligation
to deliver to such holder such shares of stock, securities or assets as, in
accordance with the foregoing provisions, such holder may be entitled to
purchase.

         7.       Notice of Adjustment of Warrant Exercise Price. Upon any
adjustment of the Warrant Exercise Price, then the Company shall give notice
thereof to the Holder of this Warrant, which notice shall state the Warrant
Exercise Price in effect after such adjustment and the increase, or decrease, if
any, in the number of Warrant Shares purchasable at the Warrant Exercise Price
upon the exercise of this Warrant, setting forth in reasonable detail the method
of calculation and the facts upon which such calculation is based.

         8.       Computation of Adjustments. Upon each computation of an
adjustment in the Warrant Exercise Price and the number of shares which may be
subscribed for and purchased upon exercise of this Warrant, the Warrant Exercise
Price shall be computed to the nearest cent (i.e. fraction of .5 of a cent, or
greater, shall be rounded to the next highest cent) and the number of shares
which may be subscribed for and purchased upon exercise of this Warrant shall be
calculated to the nearest whole share (i.e. fractions of less than one half of a
share shall be disregarded and fractions of one half of a share, or greater,
shall be treated as being a whole share). No such adjustment shall be made
however, if the change in the Warrant Exercise Price would be less than $.001
per share, but any such lesser adjustment shall be made (i) at the time and
together with the next subsequent adjustment which, together with any
adjustments carried forward, shall amount to $.001 per share or more, or (ii) if
earlier, upon the third anniversary of the event for which such adjustment is
required.

         9.       Notice of Certain Events.  In case at any time:

                  (a)  the Company shall pay any dividend upon, or make any
distribution in respect of, its Common Stock;

                  (b)  the Company shall propose to register any of its Common
Stock under the Securities Act in connection with a public offering of such
Common Stock (other than with respect to a registration statement filed on Form
S-8 or such other similar form then in effect under the Securities Act);

                  (c)  the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or other
rights;

                  (d)  there shall be any capital reorganization, or
reclassification of the capital stock, of the Company, or consolidation or
merger of the Company with, or sale of all or substantially all of its assets
to, another corporation; or

                  (e)  there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company; then, in one or more of said cases,
the Company shall give notice to the registered holder of this Warrant of the
date on which (i) the books of the Company shall close or a record shall be
taken for such dividend, distribution or subscription rights, or (ii) such
reorganization, reclassification, consolidation, merger, sale, dissolution,

shall be given not less than ten (10) days prior to the record date or the date

days prior to the action in question in the case of an action specified in
clause (ii).

         10.      No Change in Warrant Terms on Adjustment. Irrespective of any
adjustment in the Warrant Exercise Price or the number of shares of Common Stock
issuable upon exercise hereof, this Warrant, whether theretofore or thereafter
issued or reissued, may continue to express the same price and number of shares
as are stated herein and the Warrant Exercise Price and such number of shares
specified herein shall be deemed to have been so adjusted.

taxes attributable to the initial issuance of the Warrant Shares or any transfer
involved in the issue or delivery of any certificates for Warrant Shares of

any transfer of this Warrant.

         12.      Warrant Holder Not Deemed a Shareholder. No holder, as such,
of this Warrant shall be entitled to vote or receive dividends or be deemed the
holder of shares of the Company for any purpose, nor shall anything contained in
this Warrant be construed to confer upon the holder hereof, as such, any of the
rights of a shareholder of the Company or any right to vote, give or withhold
consent to any corporate action (whether any reorganization, issue of stock,
reclassification of stock, consolidation, merger, conveyance or otherwise),
receive notice of meetings, receive dividends or subscription rights, or
otherwise, prior to the issuance of record to the holder of this Warrant of the
Warrant Shares which he is then entitled to receive upon the due exercise of
this Warrant.

         13.      No Limitation on Corporate Action. No provisions of this
Warrant and no right or option granted or conferred hereunder shall in any way
limit, affect or abridge the exercise by the Company of any of its corporate
rights or powers to recapitalize, amend its Articles of Incorporation,
reorganize, consolidate or merge with or into another corporation, or to
transfer all or any part of its property or assets, or the exercise of any other
of its corporate rights and powers.

         14.      Transfer; Opinions of Counsel; Restrictive Legends. To the
extent applicable, each certificate or other document evidencing any of the
Warrant Shares shall be endorsed with the legends set forth below, and Holder
covenants that, except to the extent such restrictions are waived by the
Company, Holder shall not transfer the Warrant Shares without complying with the
restrictions on transfer described in the legends endorsed thereon;

                  (a)  The following legend under the Securities Act:

         "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD,
         TRANSFERRED, ASSIGNED, PLEDGED, OR HYPOTHECATED ABSENT AN EFFECTIVE
         REGISTRATION THEREOF UNDER SUCH ACT UNLESS THE COMPANY HAS RECEIVED AN
         OPINION OF

                                      -10-

         COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH 
         REGISTRATION IS NOT REQUIRED."

                  (b)  If required by the authorities of any state in connection
with the issuance or sale of the Warrant Shares, the legend required by such
state authority.

                  (c)  The Company shall not be required (i) to transfer on its
books either this Warrant or any Warrant Shares which shall have been
transferred in violation of any of the provisions set forth in this Section 14,
or (ii) to treat as owner of such Warrant Shares or to accord the right to vote
as such owner or to pay dividends to any transferee to whom such Warrant Shares
shall have been so transferred.

                  (d)  Any legend endorsed on a certificate pursuant to
subsection (a) or (b) of this Section 14 shall be removed (i) if the Warrant
Shares represented by such certificate shall have been effectively registered
under the Securities Act or otherwise lawfully sold in a public transaction, or
(ii) if the holder of such Warrant Shares shall have provided the Company with
an opinion from counsel, in form and acceptable to the Company and from
attorneys reasonably acceptable to the Company, stating that a public sale,
transfer or assignment of the Warrant or the Warrant Shares may be made without
registration.

                  (e)  Any legend endorsed on a certificate pursuant to
subsection (b) of this Section 14 shall be removed if the Company receives an
order of the appropriate state authority authorizing such removal or if the
holder of the Warrant or the Warrant Shares provides the Company with an opinion
of counsel, in form and substance acceptable to the Company and from attorneys
reasonably acceptable to the Company, stating that such state legend may be
removed.

                  (f)  Without in any way limiting the representations set forth
above, Holder further agrees not to make any disposition of all or any portion
of the Warrant or the Warrant Shares unless:

                       (i)  There is then in effect a registration statement
         under the Securities Act covering such proposed disposition and such
         disposition is made in accordance with such registration statement; or

                       (ii)  Holder shall have notified the Company of the
         proposed disposition and shall have furnished the Company with a
         detailed statement of the circumstances surrounding the proposed
         disposition, (A) if requested by the Company, Holder shall have
         furnished the Company with an opinion of counsel, reasonably
         satisfactory to the Company, that such disposition will not require
         registration of the Warrant or any Warrant Shares under the Securities
         Act and (B) if requested by the Company, the transferee shall have
         furnished to the Company its agreement to abide by the restrictions on
         transfer set forth herein as if it were a purchaser hereunder.

                                      -11-


<PAGE>   12



                  (g)  Notwithstanding the other provisions of this Section 14,
no such registration statement or opinion of counsel shall be required for any
transfer by a Holder, (i) if it is a partnership or a corporation, to a partner
or pro rata to its equity holder(s) of such Holder (or a third party duly
authorized to act on behalf of such Holder or its partners or equity holders),
or (ii) if he or she is an individual, to members of such individual's family
for estate planning purposes; provided, however, that the transferee agrees in
writing to be subject to the terms of this Section 14.

                  (h)  Upon delivery of the foregoing opinion of counsel and the
surrender of this Warrant to the Company at its principal office with the
Assignment Form annexed hereto as Exhibit B duly executed and funds sufficient
to pay any transfer tax, the Company shall, in the event that it determines such
transfer is permitted by the terms of this Warrant, without charge, execute and
deliver a new Warrant in the name of the assignee named in such instrument of
assignment and this Warrant shall promptly be cancelled.

                  (i)  Except as set forth in this Section 14, the Warrant and
the Warrant Shares shall be freely assignable by the Holder and its assignees.

         15.      Registration Rights. The Holder shall have the same
registration rights and related obligations with respect to the Warrant Shares
as those set forth in Article 9 (other than Section 9.1) of the Shareholders'
Agreement with respect to Registrable Securities (as defined therein) as if the
Holder were a party to such Shareholders' Agreement with respect only to such
Article 9.

         16.      Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant
is lost, stolen, mutilated or destroyed, the Company shall, on such terms as to
indemnity or otherwise as it may in its discretion impose (except in the event
of loss, theft, mutilation or destruction while this Warrant is in possession of
the Company's Escrow Agent, in which events the Company shall be solely
responsible) (which shall, in the case of a mutilated Warrant, include the
surrender thereof), issue a new Warrant of like denomination and tenor as the
Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant hall
constitute an original contractual obligation of the Company, whether or not the
allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time
enforceable by anyone.

         17.      Representation of Holder. The Holder, by the acceptance
hereof, represents that it is acquiring this Warrant for its own account for
investment and not with a view to, or sale in connection with, any distribution
hereof or of any of the shares of Common Stock or other securities issuable upon
the exercise thereof, nor with any present intention of distributing any of the
same. Upon exercise of this Warrant, the Holder will confirm in writing, in form
reasonably satisfactory to the Company, such Holder's investment intent.

         18.      Notices. All Notices, requests and other communications that
the Holder or the Company is required or elects to give hereunder shall be in
writing and shall be deemed to have been given (a) upon personal delivery
thereof, including by appropriate courier service, five (5) days after delivery
to the courier or, if earlier, upon delivery against a signed receipt therefor
or (b) upon transmission by facsimile or telecopier, which transmission is
confirmed, in either case addressed

                       HAYES MICROCOMPUTER PRODUCTS, INC.

                        WARRANT TO PURCHASE COMMON STOCK

         Hayes Microcomputer Products, Inc., a Georgia corporation (the
"Company"), hereby certifies that in consideration of cash payment of US $5.00,
MINA HAYES, the registered holder hereof, or its permitted registered assigns
("Holder"), is entitled, subject to the terms set forth below, to purchase from
the Company upon surrender of this Warrant, at any time or times on or after the
Exercise Date hereof but not after 5:00 P.M., Atlanta, Georgia time, on the
Expiration Date (as defined herein), up to 200,000 fully paid nonassessable
shares, as adjusted pursuant to this Warrant (the "Warrant Shares"), of Common
Stock (as defined herein) of the Company by payment of the applicable aggregate
Warrant Exercise Price (as defined herein) in lawful money of the United States.

         1.       Definitions.  The following words and terms as used in this
Warrant shall have the following meanings:

                  (a) "Common Stock" means (i) the Company's common stock and
(ii) any capital stock into which such "Common Stock" shall have been changed or
any capital stock resulting from a reclassification of such "Common Stock."

                  (b) "Convertible Securities" means any securities issued by
the Company which are convertible into or exchangeable for, directly or
indirectly, shares of Common Stock.

                  (c) "Exercise Date" means the earlier to occur of (i) the date
on which the Company files a registration statement on Form S-1 (or any similar
form) with the Securities and Exchange Commission in connection with a proposed
Initial Public Offering, or (ii) the date of the closing of a Significant
Transaction.

                  (d) "Expiration Date" means the date five (5) years after the
Exercise Date.



<PAGE>   2



                  (e) "Initial Public Offering" means the closing of a firm
commitment underwritten public offering pursuant to an effective registration
statement under the Securities Act covering the offer and sale of the Company's
Common Stock.

                  (f) "Market Price" means the fair market value of one share
determined as follows: (i) where there exists a public market for the Company's
Common Stock at the time of such exercise, the fair market value per share shall
be the average of the closing bid and asked prices of the Common Stock quoted in
the Over-The-Counter Market Summary or the last reported sale price of the
Common Stock or the closing price quoted on the NASDAQ National Market System or
on any exchange on which the Common Stock is listed, whichever is applicable, as
published in The Wall Street Journal for the five (5) trading days (or such
fewer number of trading days as the Company's Common Stock may have been
publicly traded) ending on the trading day prior to the date of determination of
fair market value and (ii) if at any time the Common Stock is not listed on any
domestic exchange or quoted in the NASDAQ System or the domestic
over-the-counter market, the higher of (A) the book value thereof, as determined
by any firm of independent public accountants of recognized standing selected by
the Board of Directors, as at the last day as of which such determination shall
have been made, or (B) the fair value thereof determined in good faith by the
Board of Directors as of the date which is within 15 days of the date as of
which the determination is to be made (in determining the fair value thereof,
the Board of Directors shall consider stock market valuations and price to
earnings ratios of comparable companies in similar industries). Notwithstanding
the foregoing, in the event the Warrant is exercised in connection with the
Initial Public Offering, the fair market value per share shall be the per share
price at which registered shares are sold to the public in the Initial Public
Offering. If the holder shall purchase such shares in conjunction with the
closing of any Significant Transaction, then the fair market value per share
shall mean the value received by the holders of the Company's Common Stock
pursuant to such Significant Transaction for each share of Common Stock, subject
to the closing of such Significant Transaction.

                  (g) "Securities Act" means the Securities Act of 1933, as
amended.

                  (h) "Significant Transaction" means the closing of a merger,
consolidation or reorganization of the Company with or into any other
corporation or corporations in which the Company is not the surviving entity
(other than a mere reincorporation transaction), a sale of all or substantially
all of the assets of the Company or a transaction or series of related
transactions in which the Company issues shares representing more than 50% of
the voting power of the Company, immediately after giving effect to such
transaction, to a person or persons who were not Shareholders (as defined in the
Shareholders' Agreement) immediately prior to such transaction.

                  (i) "Warrant Exercise Price" shall initially be US$0.714 per
share and shall be adjusted and readjusted from time to time as provided in this
Warrant.

                  (j) Other Definitional Provisions.
                      (i) Except as otherwise specified herein, all
         references herein (A) to any person other than the Company, shall be
         deemed to include such person's successors and

                                       -2-


<PAGE>   3



         permitted assigns, (B) to the Company shall be deemed to include the
         Company's successors and (C) to any applicable law defined or referred
         to herein, shall be deemed references to such applicable law as the
         same may have been or may be amended or supplemented from time to time.

                     (ii) When used in this Warrant, the words "herein,"
         "hereof," and "hereunder," and words of similar import, shall refer to
         this Warrant as a whole and not to any provision of this Warrant, and
         the words "Section," "Schedule," and "Exhibit" shall refer to Sections
         of, and Schedules and Exhibits to, this Warrant unless otherwise
         specified.

                    (iii) Whenever the context so requires the neuter
         gender includes the masculine or feminine, and the singular number
         includes the plural, and vice versa.

                     (iv) Any capitalized term not otherwise defined in this
         Warrant shall have the meaning ascribed to such term in that certain
         Shareholders' Agreement dated as of April 16, 1996 (the "Shareholders'
         Agreement"), by and among the Company, Dennis C. Hayes and the
         Shareholders.

         2.       Exercise of Warrant.

                  (a) Subject to the terms and conditions hereof, this Warrant
may be exercised in whole or in part, at any time during normal business hours
on or after the Exercise Date and prior to 5:00 p.m., Atlanta, Georgia time, on
the Expiration Date. The rights represented by this Warrant may be exercised by
the holder hereof then registered on the books of the Company, in whole or from
time to time in part (except that this Warrant shall not be exercisable as to a
fractional share), by (i) delivery of a written notice, in the form of the
Subscription Notice attached as Exhibit A hereto, of such holder's election to
exercise this Warrant, which notice shall specify the number of Warrant Shares
to be purchased, (ii) payment to the Company of an amount equal to the Warrant
Exercise Price multiplied by the number of Warrant Shares as to which the
Warrant is being exercised (plus any applicable issue or transfer taxes) in
cash, by wire transfer or by certified or official bank check, for the number of
Warrant Shares as to which this Warrant shall have been exercised, and (iii) the
surrender of this Warrant, properly endorsed, at the principal office of the
Company in Atlanta, Georgia (or at such other agency or office of the Company as
the Company may designate by notice to the Holder); provided, that if such
Warrant Shares are to be issued in any name other than that of the Holder, such
issuance shall be deemed a transfer and the provisions of Section 14 shall be
applicable. In the event of any exercise of the rights represented by this
Warrant, a certificate or certificates for the Warrant Shares so purchased,
registered in the name of, or as directed by, the Holder, shall be delivered to,
or as directed by the Holder within a reasonable time, not exceeding 15 days (if
the Company's Common Stock is not then publicly traded) or five (5) business
days (if the Company's Common Stock is then publicly traded), after such rights
shall have been so exercised.

                  (b) Unless the rights represented by this Warrant shall have
expired or have been fully exercised, the Company shall issue, within such 15
day or 5 business day period, as applicable,

                                       -3-

new Warrant shall represent rights to purchase the number of Warrant Shares
purchasable immediately prior to such exercise under the warrant exercised, less

exercised, and (y) the Warrant Exercise Price thereof shall be the Warrant
Exercise Price of the Warrant exercised. The person in whose name any
certificate for Warrant Shares is issued upon exercise of this Warrant shall for
all purposes be deemed to have become the holder of record of such Warrant
Shares immediately prior to the close of business on the date on which the
Warrant was surrendered and payment of the amount due in respect of such
exercise and any applicable taxes was made, irrespective of the date of delivery
of such share certificate, except that, if the date of such surrender and
payment is a date when the stock transfer books of the Company are properly
closed, such person shall be deemed to have become the holder of such Warrant
Shares at the opening of business on the next succeeding date on which the stock
transfer books are open.

                  (c) In lieu of the Holder exercising this Warrant (or any
portion hereof) for cash, it may, in connection with such exercise, elect to
satisfy the Warrant Exercise Price by exchanging solely (x) this Warrant (or
such portion hereof) for (y) that number of Warrant Shares equal to the product
of (i) the number of shares of Common Stock issuable upon such exercise of the
Warrant (or, if only a portion of this Warrant is being exercised, issuable upon
the exercise of such portion) for cash multiplied by (ii) a fraction, (A) the
numerator of which is the Market Price per share of the Common Stock at the time
of such exercise minus the Warrant Exercise Price per share of the Common Stock
at the time of such exercise, and (B) the denominator of which is the Market
Price per share of the Common Stock at the time of such exercise, such number of
shares so issuable upon such exercise to be rounded up or down to the nearest
whole number of Warrant Shares.

         3.       Covenants as to Common Stock.

                  (a) The Company covenants and agrees that all Warrant Shares
which may be issued upon the exercise of the rights represented by this Warrant
will, upon issuance, be validly issued, fully paid and nonassessable. The
Company further covenants and agrees that during the period within which the
rights represented by this Warrant may be exercised, the Company will at all
times have authorized and reserved a sufficient number of shares of Common Stock
to provide for the exercise of the rights then represented by this Warrant and
that the par value of said shares will at all times be less than or equal to the
applicable Warrant Exercise Price.

                  (b) If any shares of Common Stock reserved or to be reserved
to provide for the exercise of the rights then represented by this Warrant
require registration with or approval of any governmental authority under any
federal or state law before such shares may be validly issued to the Holder,
then the Company covenants that it will in good faith and as expeditiously as
possible endeavor to secure such registration or approval, as the case may be.

         4.       Adjustment of Warrant Exercise Price Upon Stock Splits,
Dividends, Distributions and Combinations; and Adjustment of Number of Shares.

                  (a) In case the Company shall at any time subdivide its
outstanding shares of Common Stock into a greater number of shares or issue a
stock dividend (including any distribution of stock without consideration) or
make a distribution with respect to outstanding shares of Common Stock or
convertible securities payable in Common Stock or in convertible securities, the
Warrant Exercise Price in effect immediately prior to such subdivision or stock
dividend or distribution shall be proportionately reduced and conversely, in
case the outstanding shares of Common Stock of the Company shall be combined
into a smaller number of shares, the Warrant Exercise Price in effect
immediately prior to such combination shall be proportionately increased in each
case by multiplying the then effective Warrant Exercise Price by a fraction, the
numerator of which shall be the total number of shares of Common Stock
outstanding immediately prior to such subdivision, stock dividend, distribution
or combination (determined on a fully diluted basis), and the denominator of
which shall be the total number of shares of Common Stock, immediately after
such subdivision, stock dividend, distribution or combination (determined on a
fully diluted basis), and the product so obtained shall be thereafter the
Warrant Exercise Price.

                  (b) Upon each adjustment of the Warrant Exercise Price as
provided above in this Section 4, the Holder shall thereafter be entitled to
purchase, at the Warrant Exercise Price resulting from such adjustment, the
number of shares (calculated to the nearest tenth of a share) obtained by
multiplying the Warrant Exercise Price in effect immediately prior to such
adjustment by the number of shares purchasable pursuant hereto immediately prior
to such adjustment and dividing the product thereof by the Warrant Exercise
Price immediately after such adjustment.

         5.       Adjustment of Warrant Exercise Price Upon Certain Issuances or
Sales of Common Stock. Whenever the Company shall issue, sell or otherwise
distribute any shares of its Common Stock (except for the Preferred Shares
issuable upon the conversion of the Convertible Promissory Notes, options issued
to officers and employees of the Company pursuant to plans adopted by the Board
of Directors of the Company, and shares of Common Stock issuable upon the
exercise of such options, shares of Common Stock issuable upon the conversion of
the Preferred Shares or the Warrants and except as provided in Section 6 of this
Warrant) and the amount of consideration per share is less than the Warrant
Exercise Price in effect immediately prior to the time of such issuance or sale,
then, forthwith upon such issue or sale, and thereafter successively upon each
such issue, the Warrant Exercise Price shall be reduced to the amount
(calculated to the nearest one hundredth of a cent) determined by dividing (i)
an amount equal to the sum of (x) the number of shares of Common Stock
outstanding immediately prior to such issue or sale multiplied by the then
existing Warrant Exercise Price, and (y) the consideration, if any, received by
the Company upon such issue or sale, by (ii) the total number of shares of
Common Stock outstanding immediately after such issue or sale.

                  Whenever the Warrant Exercise Price is adjusted under this
Section 5, the Holder shall thereafter be entitled to purchase at the new
Warrant Exercise Price the number of shares of Common Stock obtained by
multiplying the Warrant Exercise Price in effect immediately prior to such
adjustment by the number of shares of Common Stock purchasable pursuant hereto
immediately prior to such adjustment and dividing the product thereof by the new
Warrant Exercise Price.

                  For the purposes of this Section 5, the following clauses (i)
to (vii), inclusive, shall also be applicable:

                           (i) in case at any time the Company shall in any
         manner grant any rights to subscribe for, or any rights or options to
         purchase, any Common Stock or any Convertible Securities, whether or
         not such rights or options or the rights to convert or exchange any
         such Convertible Securities are immediately exercisable, and the
         purchase price per share for which Common Stock is issuable upon the
         exercise of such rights or options or upon conversion or exchange of
         such Convertible Securities (determined by dividing (x) the total
         amount, if any, received or receivable by the Company as consideration
         for the granting of all such rights or options, plus the minimum
         aggregate amount of additional consideration payable to the Company
         upon the exercise of all such rights or options, plus, in the case of
         such Convertible Securities, if any, payable upon, the conversion or
         exchange thereof, by (y) the maximum aggregate number of shares of
         Common Stock issuable upon the exercise of such rights or options or
         upon the conversion or exchange of all such Convertible Securities
         issuable upon the exercise of such rights or options) shall be less
         than or the Warrant Exercise Price in effect immediately prior to the
         time of the granting of such rights or options, then the maximum
         aggregate number of shares of Common Stock issuable upon the exercise
         of such rights or options or upon conversion or exchange of the total
         maximum amount of such Convertible Securities issuable upon the
         exercise of such rights or options shall (as of the date of granting of
         such rights or options) be deemed to be outstanding and to have been
         issued for such price per share. No further adjustments of the Warrant
         Exercise Price shall be made upon the actual issue of such Common Stock
         upon conversion or exchange of such Convertible Securities, except as
         otherwise provided in clause (iii) below;

                          (ii)  in case at any time the Company shall in any
         manner issue or sell any Convertible Securities, whether or not the
         rights to exchange or convert thereunder are immediately exercisable,
         and the purchase price per share for which Common Stock is issuable
         upon such conversion or exchange (determined by dividing (x) the total
         amount received or receivable by the Company as consideration for the
         issue or sale of all such Convertible Securities, plus the minimum
         aggregate amount of additional consideration, if any, payable to the
         Company upon the conversion or exchange thereof, by (y) the maximum
         aggregate number of shares of Common Stock issuable upon the conversion
         or exchange of all such Convertible Securities) shall be less than the
         Warrant Exercise Price in effect immediately prior to the time of such
         issue or sale, then the maximum aggregate number of shares of Common
         Stock issuable upon conversion or exchange of all such Convertible
         Securities shall (as of the date of the issue or sale of such
         Convertible Securities) be deemed outstanding and to have been issued
         for such price per share, provided that, except as otherwise specified
         in clause (iii) below, (a) no further adjustments of the Warrant
         Exercise Price shall be made upon the actual issue of such Common Stock
         upon conversion or exchange of such Convertible Securities, and (b) if
         any such issue or sale of such Convertible Securities is made upon
         exercise of any rights to subscribe for or to purchase or upon exercise
         of any option to purchase any such Convertible Securities for which
         adjustments of the Warrant Exercise Price have been or are to be made
         pursuant to other

                                       -6-


<PAGE>   7



         provisions of this Section 5, no further adjustment of the Warrant
         Exercise Price shall be made by reason of such issue or sale;

                         (iii) if the purchase price or number of shares
         purchasable provided for in any right or option referred to in clause
         (i) above, or the rate at which any Convertible Securities referred to
         in clause (i) or (ii) above are convertible into or exchangeable for
         Common Stock, shall change at any time (other than under or by reason
         of provisions designed to protect against dilution for which provision
         for adjustments in the Warrant Exercise Price are provided for under
         this Warrant), the Warrant Exercise Price then in effect hereunder
         shall forthwith be readjusted to such Warrant Exercise price as would
         have obtained had the adjustments made upon the issuance of such
         rights, options or Convertible Securities been made upon the basis of
         the changed terms; and on the expiration of any such option or right
         referred to in clause (i) above or the termination of any such right to
         convert or exchange such Convertible Securities referred to in clause
         (i) or (ii) above, the Warrant Exercise Price then in effect hereunder
         shall forthwith be readjusted to such Warrant Exercise Price as would
         have obtained had the adjustments made upon the issuance of such rights
         or options or Convertible Securities been made upon the basis of the
         issuance of only the number of shares of Common Stock, if any,
         theretofore actually delivered upon the exercise of such rights or
         options or upon the conversion or exchange of such Convertible
         Securities;

                         (iv)  in case the Company shall distribute to all
         holders of its Common Stock evidences of its indebtedness or assets,
         then in each such case the Warrant Exercise Price in effect immediately
         prior to such distribution shall be adjusted so that the same shall
         equal the price determined by multiplying the Warrant Exercise Price in
         effect immediately prior to the date of such distribution by a fraction
         whose numerator shall be (i) the Market Price per share of Common Stock
         immediately prior to the effective date of distribution multiplied by
         the total number of shares of Common Stock outstanding immediately
         prior to such effective date less (ii) the then fair market value (as
         reasonably determined by the Board of Directors) of the assets or
         evidences of indebtedness so distributed and whose denominator shall be
         such Market Price per share of the Common Stock multiplied by the total
         number of shares of Common Stock outstanding immediately prior to such
         effective date. Such adjustment shall be made whenever any such
         distribution is made and shall be retroactively effective as of
         immediately after the record date for the determination of stockholders
         entitled to receive such distribution;

                           (v) the consideration received for any shares of
         Common Stock or Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities issued or sold
         shall be deemed to be the amount received therefor, before deduction
         therefrom of any expenses incurred or any underwriting commissions or
         concessions paid or allowed in connection therewith; in case any shares
         of Common Stock or Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities shall be
         issued or sold for a consideration other than cash, the amount of the
         consideration other than cash (including any non-cash consideration
         received in

                                       -7-


<PAGE>   8



         respect of any acquisition by the Company of substantially all of the
         stock or assets of another entity) received by the Company for such
         shares shall be deemed to be the value of such consideration as
         determined reasonably and in good faith by the Board of Directors;

                          (vi) in case the Company shall take a record of the
         holders of its Common Stock for the purpose of entitling them (x) to
         receive a dividend or other distribution, or (y) to receive rights or
         options to subscribe for Common Stock or Convertible Securities, then
         such record date shall be deemed to be the date of the issue or sale of
         the shares of Common Stock deemed to have been issued or sold upon the
         declaration of such dividend or the making of such other distribution
         or the date of the granting of such right or option of subscription or
         purchase; and

                         (vii) the number of shares of Common Stock
         outstanding at any given time shall not include shares owned or held by
         or for the account of the Company; but the disposition of any shares so
         owned or held shall be considered an issue or sale of Common Stock for
         the purposes of this Section 5.

         6.       Reorganization, Reclassification, Etc. In case of any capital
reorganization, or of any reclassification of the capital stock of the Company
(other than a change in par value or from par value to no par value or from no
par value to par value or as a result of a split-up or combination) or in case
of the consolidation or merger of the Company with or into any other corporation
(other than a consolidation or merger in which the Company is the continuing
corporation and which does not result in the Common Stock being changed into or
exchanged for stock or other securities or property of any other person), or of
the sale of the properties and assets of the Company as, or substantially as, an
entirety to any other corporation, this Warrant shall, after such capital
reorganization, reclassification of capital stock, consolidation, merger or
sale, entitle the Holder hereof to purchase the kind and number of shares of
stock or other securities or property of the Company or of the corporation
resulting from such consolidation or surviving such merger or to which such sale
shall be made, as the case may be, to which the holder hereof would have been
entitled if he had held the Common Stock issuable upon the exercise hereof
immediately prior to such capital reorganization, reclassification of capital
stock, consolidation, merger or sale, and in any such case appropriate provision
shall be made with respect to the rights and interests of the holder of this
Warrant to the end that the provisions thereof (including without limitation
provisions for adjustment of the Warrant Exercise Price and of the number of
shares purchasable upon the exercise of this Warrant) shall thereafter be
applicable, as nearly as may be in relation to any shares of stock, securities,
or assets thereafter deliverable upon the exercise of the rights represented
hereby. The Company shall not effect any such consolidation, merger or sale,
unless prior to or simultaneously with the consummation thereof the successor
corporation (if other than the Company) resulting from such consolidation or
merger of the corporation purchasing such assets shall assume by written
instrument executed and mailed or delivered to the registered holder hereof at
the address of such holder appearing on the books of the Company, the obligation
to deliver to such holder such shares of stock, securities or assets as, in
accordance with the foregoing provisions, such holder may be entitled to
purchase.

<PAGE>   9



         7.       Notice of Adjustment of Warrant Exercise Price. Upon any
adjustment of the Warrant Exercise Price, then the Company shall give notice
thereof to the Holder of this Warrant, which notice shall state the Warrant
Exercise Price in effect after such adjustment and the increase, or decrease, if
any, in the number of Warrant Shares purchasable at the Warrant Exercise Price
upon the exercise of this Warrant, setting forth in reasonable detail the method
of calculation and the facts upon which such calculation is based.

         8.       Computation of Adjustments. Upon each computation of an
adjustment in the Warrant Exercise Price and the number of shares which may be
subscribed for and purchased upon exercise of this Warrant, the Warrant Exercise
Price shall be computed to the nearest cent (i.e. fraction of .5 of a cent, or
greater, shall be rounded to the next highest cent) and the number of shares
which may be subscribed for and purchased upon exercise of this Warrant shall be
calculated to the nearest whole share (i.e. fractions of less than one half of a
share shall be disregarded and fractions of one half of a share, or greater,
shall be treated as being a whole share). No such adjustment shall be made
however, if the change in the Warrant Exercise Price would be less than $.001
per share, but any such lesser adjustment shall be made (i) at the time and
together with the next subsequent adjustment which, together with any
adjustments carried forward, shall amount to $.001 per share or more, or (ii) if
earlier, upon the third anniversary of the event for which such adjustment is
required.

         9.       Notice of Certain Events.  In case at any time:

                  (a) the Company shall pay any dividend upon, or make any
distribution in respect of, its Common Stock;

                  (b) the Company shall propose to register any of its Common
Stock under the Securities Act in connection with a public offering of such
Common Stock (other than with respect to a registration statement filed on Form
S-8 or such other similar form then in effect under the Securities Act);

                  (c) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or other
rights;

                  (d) there shall be any capital reorganization, or
reclassification of the capital stock, of the Company, or consolidation or
merger of the Company with, or sale of all or substantially all of its assets
to, another corporation; or

                  (e) there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company; then, in one or more of said cases,
the Company shall give notice to the registered holder of this Warrant of the
date on which (i) the books of the Company shall close or a record shall be
taken for such dividend, distribution or subscription rights, or (ii) such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up shall take place, as the case may be. Such notice
shall be given not less than ten (10) days prior to the record date or the date
on which the transfer books of the Company are to be closed in respect

                                       -9-


<PAGE>   10



thereto in the case of an action specified in clause (i) and at least ten (10)
days prior to the action in question in the case of an action specified in
clause (ii).

         10.      No Change in Warrant Terms on Adjustment. Irrespective of any
adjustment in the Warrant Exercise Price or the number of shares of Common Stock
issuable upon exercise hereof, this Warrant, whether theretofore or thereafter
issued or reissued, may continue to express the same price and number of shares
as are stated herein and the Warrant Exercise Price and such number of shares
specified herein shall be deemed to have been so adjusted.

         11.      Taxes. The Company shall not be required to pay any tax or
taxes attributable to the initial issuance of the Warrant Shares or any transfer
involved in the issue or delivery of any certificates for Warrant Shares of
Common Stock in a name other than that of the registered holder hereof or upon
any transfer of this Warrant.

         12.      Warrant Holder Not Deemed a Shareholder. No holder, as such,
of this Warrant shall be entitled to vote or receive dividends or be deemed the
holder of shares of the Company for any purpose, nor shall anything contained in
this Warrant be construed to confer upon the holder hereof, as such, any of the
rights of a shareholder of the Company or any right to vote, give or withhold
consent to any corporate action (whether any reorganization, issue of stock,
reclassification of stock, consolidation, merger, conveyance or otherwise),
receive notice of meetings, receive dividends or subscription rights, or
otherwise, prior to the issuance of record to the holder of this Warrant of the
Warrant Shares which he is then entitled to receive upon the due exercise of
this Warrant.

         13.      No Limitation on Corporate Action. No provisions of this
Warrant and no right or option granted or conferred hereunder shall in any way
limit, affect or abridge the exercise by the Company of any of its corporate
rights or powers to recapitalize, amend its Articles of Incorporation,
reorganize, consolidate or merge with or into another corporation, or to
transfer all or any part of its property or assets, or the exercise of any other
of its corporate rights and powers.

         14.      Transfer; Opinions of Counsel; Restrictive Legends. To the
extent applicable, each certificate or other document evidencing any of the
Warrant Shares shall be endorsed with the legends set forth below, and Holder
covenants that, except to the extent such restrictions are waived by the
Company, Holder shall not transfer the Warrant Shares without complying with the
restrictions on transfer described in the legends endorsed thereon;

                  (a) The following legend under the Securities Act:

         "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD,
         TRANSFERRED, ASSIGNED, PLEDGED, OR HYPOTHECATED ABSENT AN EFFECTIVE
         REGISTRATION THEREOF UNDER SUCH ACT UNLESS THE COMPANY HAS RECEIVED AN
         OPINION OF

                                      -10-


<PAGE>   11



         COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH
         REGISTRATION IS NOT REQUIRED."

                  (b) If required by the authorities of any state in connection
with the issuance or sale of the Warrant Shares, the legend required by such
state authority.

                  (c) The Company shall not be required (i) to transfer on its
books either this Warrant or any Warrant Shares which shall have been
transferred in violation of any of the provisions set forth in this Section 14,
or (ii) to treat as owner of such Warrant Shares or to accord the right to vote
as such owner or to pay dividends to any transferee to whom such Warrant Shares
shall have been so transferred.

                  (d) Any legend endorsed on a certificate pursuant to
subsection (a) or (b) of this Section 14 shall be removed (i) if the Warrant
Shares represented by such certificate shall have been effectively registered
under the Securities Act or otherwise lawfully sold in a public transaction, or
(ii) if the holder of such Warrant Shares shall have provided the Company with
an opinion from counsel, in form and acceptable to the Company and from
attorneys reasonably acceptable to the Company, stating that a public sale,
transfer or assignment of the Warrant or the Warrant Shares may be made without
registration.

                  (e) Any legend endorsed on a certificate pursuant to
subsection (b) of this Section 14 shall be removed if the Company receives an
order of the appropriate state authority authorizing such removal or if the
holder of the Warrant or the Warrant Shares provides the Company with an opinion
of counsel, in form and substance acceptable to the Company and from attorneys
reasonably acceptable to the Company, stating that such state legend may be
removed.

                  (f) Without in any way limiting the representations set forth
above, Holder further agrees not to make any disposition of all or any portion
of the Warrant or the Warrant Shares unless:

                      (i) There is then in effect a registration statement
         under the Securities Act covering such proposed disposition and such
         disposition is made in accordance with such registration statement; or

                      (ii) Holder shall have notified the Company of the
         proposed disposition and shall have furnished the Company with a
         detailed statement of the circumstances surrounding the proposed
         disposition, (A) if requested by the Company, Holder shall have
         furnished the Company with an opinion of counsel, reasonably
         satisfactory to the Company, that such disposition will not require
         registration of the Warrant or any Warrant Shares under the Securities
         Act and (B) if requested by the Company, the transferee shall have
         furnished to the Company its agreement to abide by the restrictions on
         transfer set forth herein as if it were a purchaser hereunder.

                                      -11-


<PAGE>   12



                  (g) Notwithstanding the other provisions of this Section 14,
no such registration statement or opinion of counsel shall be required for any
transfer by a Holder, (i) if it is a partnership or a corporation, to a partner
or pro rata to its equity holder(s) of such Holder (or a third party duly
authorized to act on behalf of such Holder or its partners or equity holders),
or (ii) if he or she is an individual, to members of such individual's family
for estate planning purposes; provided, however, that the transferee agrees in
writing to be subject to the terms of this Section 14.

                  (h) Upon delivery of the foregoing opinion of counsel and the
surrender of this Warrant to the Company at its principal office with the
Assignment Form annexed hereto as Exhibit B duly executed and funds sufficient
to pay any transfer tax, the Company shall, in the event that it determines such
transfer is permitted by the terms of this Warrant, without charge, execute and
deliver a new Warrant in the name of the assignee named in such instrument of
assignment and this Warrant shall promptly be cancelled.

the Warrant Shares shall be freely assignable by the Holder and its assignees.

         15.      Registration Rights. The Holder shall have the same
registration rights and related obligations with respect to the Warrant Shares
as those set forth in Article 9 (other than Section 9.1) of the Shareholders'
Agreement with respect to Registrable Securities (as defined therein) as if the
Holder were a party to such Shareholders' Agreement with respect only to such

is lost, stolen, mutilated or destroyed, the Company shall, on such terms as to
indemnity or otherwise as it may in its discretion impose (except in the event
of loss, theft, mutilation or destruction while this Warrant is in possession of
the Company's Escrow Agent, in which events the Company shall be solely
responsible) (which shall, in the case of a mutilated Warrant, include the
surrender thereof), issue a new Warrant of like denomination and tenor as the
Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall
constitute an original contractual obligation of the Company, whether or not the
allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time
enforceable by anyone.

         17.      Representation of Holder. The Holder, by the acceptance
hereof, represents that it is acquiring this Warrant for its own account for
investment and not with a view to, or sale in connection with, any distribution
hereof or of any of the shares of Common Stock or other securities issuable upon
the exercise thereof, nor with any present intention of distributing any of the
same. Upon exercise of this Warrant, the Holder will confirm in writing, in form
reasonably satisfactory to the Company, such Holder's investment intent.

                                 LEASE AGREEMENT

         THIS LEASE AGREEMENT, made and entered into by and between PEACHTREE
CROSSINGS BUSINESS PARK ASSOCIATES hereinafter referred to as "Landlord" and
HAYES MICROCOMPUTER PRODUCTS, INC., a Georgia corporation, hereinafter referred
to as "Tenant."

                                   WITNESETH

         1.       Premises and Term. In consideration of the obligation of
Tenant to pay rent as herein provided, and in consideration of the other terms,
provisions and covenants hereof, Landlord hereby demises and leases to Tenant,
and Tenant hereby accepts and leases from landlord certain premises situated
within the County of Gwinnett, State of Georgia, more particularly described on
Exhibit "A" attached hereto and incorporated herein by reference, together with
all rights, privileges, easements, appurtenances, and immunities belonging to or
in any way pertaining to the premises and together with the buildings and other
improvements situated or to be situated upon said premises (said real property,
building and improvements being hereinafter referred to as the "premises.")

         TO HAVE AND TO HOLD the same for a term commencing on the "commencement
date," as hereinafter defined, and ending on the last day of the month that is
sixty (60) months after the commencement date.

         A.       The "commencement date" shall be January 1, 1991, and ending
December 31, 1995. Tenant acknowledges that it has inspected and accepts the
premises, and specifically the buildings and improvements comprising the same,
in their present condition, as suitable for the purpose for which the premises
are leased. Taking of possession by Tenant shall be deemed conclusively to
establish that said buildings and other improvements are in good and
satisfactory condition as of when possession was taken. Tenant further
acknowledges that no representations as to the repair of the premises, nor
promises to alter, remodel or improve the premises have been made by Landlord,
unless such are expressly set forth in this lease. If this lease is executed
before the premises become vacant or otherwise available and ready for
occupancy, or if any present tenant or occupant of the premises holds ver, the
Landlord cannot acquire possession of the premises prior to said "commencement
date." Landlord shall not be deemed to be in default hereunder, and Tenant
agrees to accept possession of the premises at such time as Landlord is able to
tender the same, which date shall thenceforth be deemed the "commencement date,"
and Landlord hereby waives payment of rent covering any period prior to the
tendering of possession to Tenant hereunder. After the commencement date the
Tenant shall, upon demand, execute and deliver to Landlord a letter of
acceptance of delivery of the premises.

         B.       Omitted.

         2.       Base Rent and Security Deposit.  See Additional Provision #29.

         A.       Omitted.

         B.       In addition, Tenant has deposited with Landlord the sum of
TWENTY-SIX THOUSAND THIRTEEN AND NO/100 DOLLARS ($26,013.00), which sum shall be
held by Landlord, without obligation for interest, as security for the
performance of Tenant's covenants and obligations under this lease, it being
expressly understood and agreed that such deposit is not an advance rental
deposit or a measure of Landlord's damages in case of Tenant's default. Upon the
occurrence of any event of default by Tenant, Landlord may, from time to time,
without prejudice to any other remedy provided herein or provided by law, use
such fund to the extent necessary to make good any arrears of rent or other
payments due Landlord hereunder, and any other damage, injury, expense or
liability caused by such event of default, and Tenant shall pay to Landlord on
demand the amount so applied in order to restore the security deposit to its
original amount. Although the security deposit shall be deemed the property of
Landlord, any remaining balance of such deposit shall be returned by Landlord to
Tenant at such time after termination of this lease that all of Tenant's
obligations under this lease have been fulfilled.

         3.       Use. The demised premises shall be used only for the purpose
of general office, receiving, storing, manufacturing, repairing, shipping and
selling (other than retail) products, materials and merchandise made and or
distributed by Tenant and for such other lawful purposes as may be incidental
thereto, and subject to any building or building complex rules and regulations
which shall not impair Tenant's use of the premises. Outside storage, including
without limitation, trucks and other vehicles, is prohibited without Landlord's
prior written consent. Tenant shall at its own cost and expense obtain any and
all licenses and permits necessary for any such use. Tenant shall comply with
all governmental laws, ordinances and regulations applicable to the use of the
premises, and shall promptly comply with all governmental orders and directives
for the correction, prevention and abatement of nuisances in or upon, or
connected with the premises, all at Tenant's sole expense. Tenant shall not
permit any objectionable or unpleasant odors, smoke, dust, gas, noise or
vibrations to emanate from the premises, nor take any other action which would
constitute a nuisance or would disturb or endanger any other tenants of the
building in which their premises are situated or unreasonably interfere with
their use of their respective premises. Without Landlord's prior written
consent, Tenant shall not receive, store or otherwise handle any product,
material or merchandise which is explosive or highly flammable. Tenant will not
permit the premises to be used for any purpose or in any manner, including,
without limitation, any method of storage which would render the insurance
thereon void or the insurance risk more hazardous or cause the State Board of
insurance or other insurance authority to disallow any sprinkler credits. If any
increase in the fire and extended coverage insurance premiums paid by Landlord
or other tenants for the building in which Tenant occupies space is caused by
Tenant's use and occupancy of the premises, or if Tenant vacates the premises
and causes an increase in such premiums, then Tenant shall pay as additional
rental the amount of such increase to Landlord.


                                      - 2 -

<PAGE>   3



         Tenant agrees that the point pressure resulting from Tenant's racking
system, inventory, forklifts and equipment pertaining to Tenant's use of the
premises shall not exceed allowable design floor loading for floor slabs on
grade. Tenant shall hold harmless Landlord from any loss, liability, and
expenses, both real and alleged, arising out of such damage or repair caused by
Tenant's negligence or failure to comply with this paragraph.

         4.       Taxes.

         A.       Landlord agrees to pay before they become delinquent all
taxes, assessments and governmental charges of any kind and nature whatsoever
thereinafter collectively referred to as "taxes" lawfully levied or assessed
against the building and the grounds, parking areas, driveways and alleys around
the building; provided, however, that the maximum amount of taxes to be paid by
Landlord hereunder during any one real estate tax year shall be ZERO AND NO/100
DOLLARS ($0.00). If in any real estate tax year during the term hereof or any
renewal or extension the taxes levied or assessed against the building and the
grounds, parking areas, driveways and alleys around the building during such tax
year shall exceed the sum set forth in the preceding sentence, Tenant shall pay
to Landlord as additional rental, upon demand, the amount of such excess. In the
event any such amount is not paid within twenty (20) days after the date of
Landlord's invoice to Tenant, the unpaid amount shall bear interest at the rate
of twenty (20%) percent per annum from the date of such invoice until payment by
Tenant. In the event the premises constitute a portion of a multiple occupancy
building, Tenant agrees to pay to Landlord as additional rental, upon demand,
the amount of Tenant's "proportionate share" (as defined in subparagraph 27B) of
the excess taxes referred to in this subparagraph above.

         B.       If at any time during the term of this lease, the present
method of taxation shall be changed so that in lieu of the whole or any part of
any taxes, assessments, or governmental charges levied, assessed or imposed on
real estate and the improvements thereon, there shall be levied, assessed or
imposed on Landlord a capital levy or other tax directly on the rents received
therefrom and/or a franchise tax, assessment, levy or charge measured by or
based, in whole or in part, upon such rents for the present or any future
building or buildings on the premises, then all such taxes, assessments, levies
or charges, or the part thereof so measured or based shall be deemed to be
included within the term "taxes" for the purposes hereof.

         C.       The Landlord shall have the right to engage a tax consulting
firm to attempt to assure a fair tax burden for the building and grounds within
the applicable taxing jurisdiction. Tenant shall pay to Landlord upon demand,
from time to time, as additional rent, the amount of Tenant's proportionate
share of the cost of such service.

         D.       Any payment to be made pursuant to this Paragraph 4 with
respect to the real estate tax year in which this lease commences or terminates
shall be prorated.

         5.       Landlord's Repairs and Obligations. Landlord shall at his
expense maintain only the roof, foundation and the structural soundness of the
exterior walls of the building in good repair, reasonable wear and tear
excepted. Tenant shall repair and pay for any damage caused by the

                                      - 3 -

<PAGE>   4



negligence of Tenant, or Tenant's employees, agents or invitees, or caused by
Tenant's default hereunder. The term "walls' as used herein shall not include
windows, glass or plate glass, doors, store fronts or office entries. Tenant
shall immediately give Landlord written notice of defect or need for repairs,
after which Landlord shall have reasonable opportunity to repair same or cure
such defect. Landlord's liability with respect to any defects, repairs or
maintenance for which Landlord is responsible under any of the provisions of
this lease shall be limited to the cost of such repairs or maintenance or the
curing of such defect.

         6.       Tenant's Repairs and Obligations.

         A.       Tenant shall at its own cost and expense keep and maintain all
parts of the premises (except those for which Landlord is expressly responsible
under the terms of this lease) in good condition, promptly making all necessary
repairs, repainting, and replacements, including but not limited to, windows,
glass and plate glass, doors, any office entries, interior walls and finish
work, floors and floor covering, downspouts, gutters, heating and air
conditioning systems, dock boards, truck doors, dock bumpers, paving, plumbing
work and fixtures, termites and pest extermination, regular removal of trash and
debris, grounds maintenance, common sewage line plumbing, common exterior
lighting (if applicable), common dumpster removal (if applicable) and other
obligations of the building, including, but not limited to, keeping the parking
areas, driveways, alleys and the whole of the premises in a clean and sanitary
condition. Tenant shall not be obligated to repair any damage caused by fire,
tornado or other casualty covered by the insurance to be maintained by Landlord
pursuant to subparagraph 12A below, except that Tenant shall be obligated to
repair all wind damage to glass except with respect to tornado or hurricane
damage.

         B.       The cost of maintenance and repair of any common party walls
(any wall, divider, partition or any other structure separating the premises
from any adjacent premises) shall be shared equally by Tenant and the tenant or
tenants occupying adjacent premises. Tenant shall not damage any demising wall
or disturb the integrity and support provided by any demising wall and shall, at
its sole cost and expense, promptly repair any damage or injury to any demising
wall caused by Tenant or its employees, agents or invitees.

         C.       In the event the premises constitute a portion of a multiple
occupancy building, Tenant and its employees, customers and licensees shall have
the exclusive right to use the parking areas, if any, as may be designated by
Landlord in writing, subject to such reasonable rules and regulations as
Landlord may from time to time prescribe and subject to rights of ingress and
egress of other tenants. Landlord shall not be responsible for enforcing
Tenant's exclusive parking rights against any third parties. Parking spaces have
been provided in accordance with applicable local building codes and anticipated
needs of tenants. Tenant agrees not to use more than its proportionate share as
so provided.

         D.       Landlord reserves the right to perform and provide all of
Tenant's repairs and obligations under subparagraph 6A above, and Tenant shall,
in lieu of the obligations set forth under subparagraph 6A above with respect to
such items, pay monthly as additional rent due under Paragraph 2A for its
proportionate share of the cost and expense, including overhead, for those

                                      - 4 -

<PAGE>   5



items; provided, however, that Landlord shall have the right to require Tenant
to pay such other reasonable proportions of said repairs and obligations as may
be determined by Landlord in its sole discretion; and further provided that if
Tenant or any other particular tenant of the building can be clearly identified
as being responsible for obstructions or stoppage of the common sanitary sewage
line, then Tenant, if Tenant is responsible, shall pay the entire cost thereof,
upon demand, as additional rent.

         E.       Omitted.

         F.       Tenant shall, at its own cost and expense, enter into a
regularly scheduled preventive maintenance/service contract with a maintenance
contractor and the contract must be approved by Landlord. The service contract
must include all services suggested by the equipment manufacturer within the
operation/maintenance manual and must become effective (and a copy thereof
delivered to Landlord) within thirty (30) days of the date Tenant takes
possession of the premises.

         7.       Alterations. Tenant shall not make any alterations, additions
or improvements to the premises (including, but not limited to, roof and wall
penetrations) without the prior written consent of Landlord. Such consent will
not be denied provided the improvements are building standard office/warehouse
finishes. In the event Landlord consents to the making of any such alterations,
additions or improvements by Tenant, the same shall be made by Tenant, at
Tenant's sole cost and expense, in accordance with all applicable laws,
ordinances and regulations, and all requirements of Landlord's and Tenant's
insurance policies and only in accordance with plans and specifications approved
by Landlord; and any contractor or person selected by Tenant to make the same
and all subcontractors must first be approved in writing by Landlord. Tenant
may, without the consent of Landlord, but at its own cost and expense and in a
good workmanlike manner erect such shelves, bins, machinery and trade fixtures
as it may deem advisable, without altering the basic character of the building
or improvements and without overloading or damaging such building or
improvements, and in each case complying with all applicable governmental laws,
ordinances, regulations and other requirements. All alterations, additions,
improvements and partitions erected by Tenant shall be and remain the property
of Tenant during the term of this lease and Tenant shall, unless Landlord
otherwise elects as hereinafter provided, remove all alterations, additions,
improvements and partitions erected by Tenant and restore the premises to their
original condition by the date of termination of this lease or upon earlier
vacating of the premises; provided, however, that if Landlord so elects prior to
termination of this lease or upon earlier vacating of the premises, such
alterations, additions, improvements and partitions shall become the property of
Landlord as of the date of termination of this lease or upon earlier vacating of
the premises and shall be delivered up to the Landlord with the premises. All
shelves, bins, machinery and trade fixtures installed by Tenant may be removed
by Tenant prior to the termination of this lease if Tenant so elects, and shall
be removed by the date of termination of this lease or upon earlier vacating of
the premises if required by Landlord; upon any such removal Tenant shall restore
the premises to their original condition with consideration for normal wear and
tear. All such removals and restoration shall be accomplished in a good
workmanlike manner so as not to damage the primary structure or structural
qualities of the building and other improvements situated on the premises.

         8.       Signs. Tenant agrees to conform to Landlord's signage program
for the building; however, all costs and expense of the sign, sign installation,
removal and repair shall be paid by Tenant. Tenant shall only have the right to
install standard signs upon the premises where first approved in writing by
Landlord and subject to any applicable governmental laws, ordinances,
regulations and other requirements. Tenant shall remove all signs prior to the
termination of this lease. Such installations and removals shall be made in such
a manner as to avoid injury or defacement of the building and other
improvements, and Tenant shall repair any injury or defacement, including,
without limitation, discoloration caused by installation and/or removal.

         9.       Inspection and Right of Entry. Landlord and Landlord's agents
and representatives shall have the right to enter the premises at any time in
the event of an emergency and to enter and inspect the premises at any
reasonable time during business hours, for the purpose of ascertaining the
condition of the premises in order to make such repairs as may be required or
permitted to be made by Landlord under the terms of this lease. During the
period that is six (6) months prior to the end of the term hereof, Landlord and
Landlord's agents and representatives shall have the right to enter the premises
at any reasonable time during business hours for the purpose of showing the
premises and shall have the right to erect on the premises a suitable sign
indicating the premises are available. Tenant shall arrange to meet with
Landlord for a joint inspection of the premises prior to vacating. In the event
of Tenant's failure to arrange such joint inspection, Landlord's inspection at
or after Tenant's vacating the premises shall be conclusively deemed correct for
purposes of determining Tenant's responsibility for repairs and restoration.

         10.      Utilities. Landlord agrees to provide at its cost water,
electricity and gas (when applicable) service connections into the premises; but
Tenant shall pay for all water, gas, heat, light, power, telephone, sewer,
sprinkler charges and other utilities and services used on or from the premises,
together with any taxes, penalties, surcharges or the like pertaining thereto
and any maintenance charges for utilities and shall furnish all electric light
bulbs and tubes. If any such services are not separately metered to Tenant,
Tenant shall pay a reasonable proportion as determined by Landlord of all
charges jointly metered with other premises, provided, however, Landlord shall
have the right to require Tenant to pay such other reasonable proportion of said
jointly metered charges as may be determined by Landlord in its sole discretion.
Landlord shall in no event by liable for any interruption or failure of utility
services on the premises.

         11.      Assignment and Subletting.

         A.       Tenant shall not have the right to assign, sublet, transfer or
encumber this lease, or any interest therein, without the prior written consent
of Landlord. Any attempted assignment, subletting, transfer or encumbrance by
Tenant in violation of the terms and covenants of this Paragraph shall be void.
All cash or other proceeds of any assignment, such proceeds as exceed the
rentals called for hereunder in the case of a subletting and all cash or other
proceeds of any other transfer of Tenant's interest in this lease shall be paid
to Landlord, whether such assignment, subletting or other transfer is consented
to by Landlord or not, unless Landlord agrees to the contrary in writing, and
Tenant hereby assigns all rights it might have or ever acquire in any such
proceeds to Landlord. Any assignment, subletting or other transfer of Tenant's
interest in this lease shall be

                                      - 6 -

<PAGE>   7



for an amount equal to the then fair market value of such interest. These
covenants shall run with the land and shall bind Tenant and Tenant's heirs,
executors, administrators, personal representatives, representatives in any
bankruptcy proceeding, successors and assigns. any assignee, sublessee or
transferee of Tenant's interest in this lease (all such assignees, sublessees
and transferees being hereinafter referred to as "successors"), by assuming
Tenant's obligations hereunder shall assume liability to Landlord for all
amounts paid to persons other than Landlord by such successors in contravention
of this Paragraph. No assignments, subletting or other transfer, whether
consented to by Landlord or not, shall relieve Tenant of its liability
hereunder. Upon the occurrence of an "event of default" as hereinafter defined,
if the premises or any part thereof are then assigned or sublet, Landlord, in
addition to any other remedies herein provided, or provided by law, may at its
option collect directly form such assignee or subtenant all rents becoming due
to Tenant under such assignment or sublease and apply such rent against any sums
due to Landlord from Tenant hereunder, and no such collection shall be construed
to constitute a novation or a release of Tenant from the further performance of
Tenant's obligations hereunder.

         B.       If this lease is assigned to any person or entity pursuant to
the provisions of the Bankruptcy Code 11 U.S.C. ss. 101, et seq. (the
"Bankruptcy Code"), any and all monies or other considerations payable or
otherwise to be delivered in connection with such assignment shall be paid or
delivered to Landlord, shall be and remain the exclusive property of Landlord
and shall not constitute property of Tenant or of the estate of Tenant within
the meaning of the Bankruptcy Code. Any and all monies or other considerations
constituting Landlord's property under the preceding sentence not paid or
delivered to Landlord shall be held in trust for the benefit of the Landlord and
promptly paid or delivered to Landlord.

         C.       Any person or entity to which this lease is assigned pursuant
to the provisions of the Bankruptcy Code, shall be deemed, without further act
or deed, to have assumed all of the obligations arising under this lease on and
after the date of such assignment. Any such assignee shall upon demand execute
and deliver to Landlord an instrument confirming such assumption.

         12.      Fire and Casualty Damage.

         A.       Landlord agrees to maintain insurance covering the building of
which the premises are a part (including building standard office/warehouse
finishes which are constructed by Tenant) in an amount not less than eighty
percent (80%) (or such greater percentage as may be necessary to comply with the
provisions of any co-insurance clauses of the policy) of the replacement costs
thereof, insuring against the perils of Fire, Lightning, Extended Coverage,
Vandalism and Malicious Mischief, extended by Special Extended Coverage
Endorsement to insure against all other regulatory authority for the state in
which the premises are situated for use by insurance companies admitted in such
state for the writing of such insurance on risks located within such state.
Subject to the provisions of subparagraphs 12C, 12D and 12E below, such
insurance shall be for the sole benefit of Landlord and under its sole control.
If, during the second calendar year after the commencement date of this lease,
or during any subsequent calendar year of the primary term or any renewal or
extension, Landlord's cost of maintaining such insurance shall exceed Landlord's
cost of maintaining such insurance for the first calendar year or the term
hereof, Tenant agrees to pay to Landlord, as

                                      - 7 -

<PAGE>   8



additional rental, the amount of such excess not to exceed $3,996.00 per year
(or in the event the premises constitute a portion of a multiple occupancy
building, Tenant's full proportionate share of such excess). The first calendar
year shall be the year in which the lease commences. Said payments shall be made
to Landlord within ten (10) days after presentation to Tenant of Landlord's
statement setting forth the amount due. Any payment to be made pursuant to this
subparagraph A with respect to the year in which this lease commences or
terminates shall bear the same ratio to the payment which would be required to
be made for the full year as the part of such year covered by the term of this
lease bears to a full year.

         B.       If the buildings situated upon the premises should be damaged
or destroyed by fire, tornado or other casualty, Tenant shall give immediate
written notice thereof to Landlord.

         C.       If the buildings situated upon the premises should be totally
destroyed by fire, tornado or other casualty, or if they should be so damaged
thereby that rebuilding or repairs cannot in Landlord's reasonable estimation be
completed within one hundred twenty (120) days after the date upon which
Landlord is notified by Tenant of such damage, this lease shall terminate and
the rent shall be abated during the unexpired portion of this lease, effective
upon the date of the occurrence of such damage.

         D.       If the buildings situated upon the premises should be damaged
by any peril covered by the insurance to be provided by Landlord under
subparagraph 12A above, but only to such extent that rebuilding or repairs can
in Landlord's reasonable estimation be completed within one hundred twenty (120)
days after the date upon which Landlord is notified by Tenant of such damage,
this lease shall not terminate, and Landlord shall at its sole cost and expense
thereupon proceed with reasonable diligence to rebuild and repair such buildings
to substantially the condition in which they existed prior to such damage,
except that Landlord shall not be required to rebuild, repair or replace any
part of the partitions, fixtures, additions and other improvements which may
have been placed in, on or about the premises by Tenant and except that Landlord
may elect not to rebuild if such damage occurs during the last year of the term
of the lease exclusive of any option which is unexercised at the time of such
damage. If the premises are untenantable in whole or in part following such
damage, the rent payable hereunder during the period in which they are
untenantable shall be reduced to such extent as may be fair and reasonable under
all of the circumstances. In the event that Landlord should fail to complete
such repairs and rebuilding within one hundred twenty (120) days after the date
upon which Landlord is notified by Tenant of such damage, Tenant may at its
option terminate this lease by delivering written notice of termination to
Landlord as Tenant's exclusive remedy, whereupon all rights and obligations
hereunder shall cease and terminate.

         E.       Notwithstanding anything herein to the contrary, in the event
the holder of any indebtedness secured by a mortgage or deed of trust covering
the premises requires that the insurance proceeds be applied to such
indebtedness, then Landlord shall have the right to terminate this lease by
delivering written notice of termination to Tenant within fifteen (15) days
after such requirement is made by any such holder, whereupon all rights and
obligations hereunder shall cease and terminate.


                                      - 8 -

         F.       Each of Landlord and Tenant hereby releases the other from any
loss or damage to property caused by fire or any other perils insured in
policies of insurance covering such property, even if such loss or damage shall
have been caused by the fault or negligence of the other party, or anyone for
whom such other party may be responsible. Each of the Landlord and Tenant agrees
that it will request its insurance carriers to include in its policies such a
clause or endorsement. If extra cost shall be charged therefore, each party
shall advise the other thereof and of the amount of the extra cost, and the
other party, at its election, may pay the same, but it shall not be obligated to
do so.

         13.      Liability. Landlord shall not be liable to Tenant or Tenant's
employees, agents, patrons or visitors, or to any other person whomsoever, for
any injury to person or damage to property on or about the premises, resulting
from and or caused in part or whole by the negligence or misconduct of Tenant,
its agents, servants or employee or any other person entering upon the premises,
or caused by the buildings and improvements located on the premises becoming out
of repair, or caused by leakage of gas, oil, water or steam or by electricity
emanating from the premises, or due to any cause whatsoever, and Tenant hereby
covenants and agrees that it will at all times indemnify and hold safe and
harmless the property, the Landlord (including without limitation the trustee
and beneficiaries if Landlord is a trust). landlord's agents and employees from
any loss, liability, claims, suits, costs, expenses, including without
limitation attorney's fees and damages, both real and alleged, arising out of
any such damage or injury, except injury to persons or damage to property the
cause of which is the negligence of Landlord or the failure of Landlord to
repair any part of the premises which Landlord is obligated to repair and
maintain hereunder within a reasonable time after the receipt of written notice
from Tenant of needed repairs. Tenant shall procure and maintain throughout the
term of this lease a policy or policies of insurance, at its sole cost and
expense, insuring both Landlord and Tenant against all claims, demands or
actions arising out of or in connection with: (i) the premises; (ii) the
condition of the premises; (iii) Tenant operations in and maintenance and use of
the premises; and (iv) Tenant's liability assumed under this lease, the limits
of such policy or policies to be in the amount of not less than $1,000,000.00
per occurrence in respect to injury to persons (including death), and in the
amount of not less than $100,000 per occurrence in respect to property damage or
destruction, including loss of use thereof. All such policies shall be procured
by Tenant from responsible insurance companies satisfactory to Landlord.
Certificates evidencing such policies, together with receipt evidencing payment
of premiums therefor, shall be delivered to Landlord prior to the commencement
date of this lease. Not less than fifteen (15) days prior to the expiration date
of any such policies, certificates evidencing the renewals thereof (bearing
notations evidencing the payment of renewal premiums) shall be delivered to
Landlord. Such policies shall further provide that not less than thirty (30)
days written notice shall be given to Landlord before such policy may be
cancelled or changed to reduce insurance provided thereby.

         14.      Condemnation.

         A.       If the whole or any substantial part of the premises should be
taken for any public or quasi-public use under governmental law, ordinance or
regulation, or by right of eminent domain, or by private purchase in lieu
thereof and the taking would prevent or materially interfere with the

                                      - 9 -

<PAGE>   10



use of the premises for the purposes for which they are being used, this lease
shall terminate and the rent shall be abated during the unexpired portion of
this lease, effective when the physical taking of said premises shall occur.

         B.       If part of the premises shall be taken for any public or
quasi-public use under any governmental law, ordinance or regulation, or by
right of eminent domain, or by private purchase in lieu thereof, and this lease
is not terminated as provided in the subparagraph above, this lease shall not
terminate but the rent payable hereunder during the unexpired portion of this
lease shall be reduced to such extent as may be fair and reasonable under all of
the circumstances.

         C.       All compensation awarded for any taking (or the proceeds of
private sale in lieu thereof) of the premises, buildings or other improvements,
or any part thereof, shall be the property of Landlord and Tenant hereby assigns
its interest in any such award to Landlord; provided, however, Landlord shall
have no interest in any award made to Tenant for loss of business or for the
taking of Tenant's fixtures and improvements if a separate award for such items
is made to Tenant.

         15.      Holding Over. Tenant will, at the termination of this lease by
lapse of time or otherwise, yield up immediate possession to Landlord with all
repairs and maintenance required herein to be performed by Tenant completed. If
Landlord agrees in writing that Tenant may hold over after the expiration or
termination of this lease, unless the parties hereto otherwise agree in writing
on the terms of such holding over, the hold over tenancy shall be subject to
termination by Landlord at any time upon not less than five (5) days advance
written notice, or by Tenant at any time upon not less than thirty (30) days
advance written notice, and all of the other terms and provisions of this lease
shall be applicable during that period, except that Tenant shall pay Landlord
from time to time upon demand, as rental for the period of any hold over, an
amount equal to double the rent in effect on the termination date, computed on a
daily basis for each day of the hold over period. No holding over by Tenant,
whether with or without consent of Landlord, shall operate to extend this lease
except as otherwise expressly provided. The preceding provisions of this
paragraph 15 shall not be construed as consent for Tenant to hold over.

         16.      Quiet Enjoyment. Landlord covenants that it now has good title
to the premises, free and clear of all liens and encumbrances, excepting only
the lien for current taxes not yet due, such mortgage or mortgages as are
permitted by the terms of this lease, zoning ordinances and other building and
fire ordinances and governmental regulations relating to the use of such
property, and easements, restrictions and other conditions of record. Landlord
represents and warrants that it has full right and authority to enter into this
lease and that Tenant, upon paying the rental herein set forth and performing
its other covenants and agreements herein set forth, shall peaceably and quietly
have, hold and enjoy the premises for the term hereof without hindrance or
molestation from Landlord, subject to the terms and provisions of this lease.

         17.      Events of Default. The following events shall be deemed to be
events of default by Tenant under this lease:

         A.       Tenant shall fail to pay any installment of the rent herein
reserved when due, or any other payment or reimbursement to Landlord required
herein when due, and such failure shall continue for a period of ten (10) days
from the date such payment was due.

         B.       Tenant or any guarantor of Tenant's obligations hereunder
shall generally not pay its debts as they become due or shall admit in writing
its inability to pay its debts or shall make a general assignment for the
benefit of creditors, or Tenant or any such guarantor shall commence any case,
proceeding or other action seeking to have an order for relief entered on its
behalf as a debtor or to adjudicate it as bankrupt or insolvent, or seeking
reorganization, arrangement, adjustment, liquidation, dissolution, or
composition of it or its debts under any law relating to bankruptcy, insolvency,
reorganization or relief of debtors or seeking appointment of a receiver,
trustee, custodian or other similar official for it or for all or of any
substantial part of its property, or Tenant or any such guarantor shall take any
action to authorize or in contemplation of any of the actions set forth above in
this paragraph, or

         C.       Any case, proceeding or other action against Tenant or any
guarantor of Tenant's obligations hereunder shall be commenced seeking to have
an order for relief entered against it as debtor or to adjudicate it as bankrupt
or insolvent, or seeking reorganization, arrangement, adjustment, liquidation,
dissolution or composition of it or its debts under any law relating to
bankruptcy, insolvency, reorganization or relief of debtors, or seeking
appointment of a receiver, trustee, custodian or other similar official for it
or for all or any substantial part of its property.

         D.       A receiver to trustee shall be appointed for all or

premises in violation of Paragraph 22 hereof within twenty (20) days after any
such lien or encumbrance is filed against the premises.

         G.       Tenant shall fail to comply with any term, provision or
covenant of this lease (other than the foregoing in this Paragraph 17), and
shall not cure or commence to cure and diligently pursue to completion such
failure within twenty (20) days after written notice thereof to Tenant.

         H.       Tenant shall fail to continuously operate its business at the
premises for the permitted use set forth in Paragraph 3 whether or not Tenant is
in default of the rental payments due under this lease.

         18.      Remedies.

         A.       Upon the occurrence of any of such events of default described
in Paragraph 17 hereof, Landlord shall have the option to pursue any one or more
of the following remedies without any notice or demand whatsoever:

                                     - 11 -

<PAGE>   12



                  (1)      Terminate this lease, in which event Tenant shall
                           immediately surrender the premises to Landlord, and
                           if Tenant fails so to do, Landlord may, without
                           prejudice to any other remedy which it may have for
                           possession or arrearage in rent, enter upon and take
                           possession of the premises and expel or remove Tenant
                           and any other person who may be occupying such
                           premises or any part thereof, by force it necessary,
                           without being liable for prosecution or any claim of
                           damage therefore.

                  (2)      Enter upon and take possession of the premises and
                           expel or remove Tenant and any other person who may
                           be occupying such premises or any part thereof, by
                           force if necessary, without being liable for
                           prosecution or any claim for damages therefore.

                  (3)      Enter upon the Premises, by force if necessary,
                           without being liable for prosecution or any claim for
                           damages therefore, and do whatever Tenant is
                           obligated to do under the terms of this lease; and
                           Tenant agrees to reimburse Landlord on demand for any
                           expenses which Landlord may incur in thus effecting
                           the compliance with Tenant's obligations under this
                           Lease, and Tenant further agrees that Landlord shall
                           not be liable for any damages resulting to the Tenant
                           from such action, whether caused by the negligence of
                           Landlord or otherwise.

                  (4)      Alter all locks and other security devices at the
                           premises without terminating this lease.

         B.       In the event Landlord may elect to regain possession of the
premises by a forcible detainer proceeding, Tenant hereby specifically waives
any statutory notice which may be required prior to such proceeding, and agrees
that Landlord's execution of this lease is, in part, consideration of this
waiver.

         C.       In the event Tenant fails to pay any installment of rent
hereunder as and when such installment is due, to help defray the additional
cost to Landlord for processing such late payments Tenant shall pay to Landlord
on demand a late charge in an amount equal to five (5%) percent of such
installment; and the failure to pay such amount within five (5) days after
demand therefore shall be an event of default hereunder. The provision for such
late charge shall be in addition to all of Landlord's other rights and remedies
hereunder or at law and shall not be construed as liquidated damages or as
limiting Landlord's remedies in any manner.

         D.       In the event Tenant's check, given to Landlord in payment, is
returned by the bank for non-payment, Tenant agrees to pay all expenses incurred
by Landlord as a result thereof.

         E.       Exercise by Landlord of any one or more remedies hereunder
granted or otherwise available shall not be deemed to be an acceptance or
surrender of the premises by Tenant, whether by agreement or by operation of
law, it being understood that such surrender can be effected only


                                     - 12 -

<PAGE>   13



by the written agreement of Landlord and Tenant. No such alteration of locks or
other security devices and no removal or other exercise of dominion by Landlord
over the property of Tenant or others at the premises shall be deemed
unauthorized or constitute a conversion, Tenant hereby consenting, after any
event of default, to the aforesaid exercise of dominion over Tenant's property
within the premises. All claims for damages by reason of such re-entry and/or
repossession and/or alteration of locks or other security devices are hereby
waived, as are all claims for damages by reason of any distress warrant,
forcible detainer proceedings, sequestration proceedings or other legal process.
Tenant agrees that any re-entry by Landlord may be pursuant to judgment obtained
in forcible detainer proceedings or other legal proceedings or without the
necessity for any legal proceedings, as Landlord may elect, and Landlord shall
not be liable for trespass or otherwise.

         F.       Omitted.

         G.       In the event that Landlord elects to repossess the premises
without terminating the lease, or in the event Landlord elects to terminate the
lease, then Tenant, at Landlord's option, shall be liable for and shall pay to
Landlord, at the address specified for notice to Landlord herein, all rental and
other indebtedness accrued to the date of such repossession, plus rental
required to be paid by Tenant to Landlord during the remainder of the lease term
until the date of expiration of the term as stated in Paragraph 1 diminished by
any net sums thereafter received by Landlord through reletting the premises
during said period (after deducting expenses incurred by Landlord as provided in
subparagraph 18H below). In no event shall Tenant be entitled to any excess of
any rental obtained by reletting over and above the rental herein reserved.
Actions to collect amounts due by Tenant to Landlord under this subparagraph may
be brought from time to time, on one or more occasions, without the necessity of
Landlord's waiting until expiration of the lease term.

         H.       In case of any event of default or breach by Tenant, or
threatened or anticipatory breach or default, Tenant shall also be liable for
and shall pay to Landlord, at the address specified for notice to Landlord
herein, in addition to any sum provided to be paid above, brokers' fees incurred
by Landlord in connection with reletting the whole or any part of the premises;
the costs of removing and storing Tenant's or other occupant's property; the
costs of repairing, altering, remodeling or otherwise putting the premises into
condition acceptable to a new tenant or tenants, and all reasonable expenses
incurred by Landlord in enforcing or defending Landlord's rights and/or remedies
including reasonable attorney's fees.

         I.       In the event of termination or repossession of the premises
for an event of default, Landlord shall not have any obligation to relet or to
attempt to relet the premises, or any portion thereof; and in the event of
reletting, Landlord may relet the whole or any portion of the premises for any
period to any tenant and for any use and purpose.

         J.       If Tenant should fail to make any payment or cure any default
hereunder within the time herein permitted, Landlord, without being under any
obligation to do so and without thereby waiving such default, may make such
payment and/or remedy such other default for the account of Tenant (and enter
the premises for such purpose), and thereupon Tenant shall be obligated to, and

                                     - 13 -

<PAGE>   14



hereby agrees, to pay Landlord upon demand, all costs, expenses and
disbursements (including reasonable attorney's fees) incurred by Landlord in
taking such remedial action.

         K.       In the event that Landlord shall have taken possession of the
premises pursuant to the authority herein granted then Landlord shall have the
right to keep in place and use all of the furniture, fixtures and equipment at
the premises, including that which is owned by or leased to Tenant at all times
prior to any foreclosure thereon by Landlord or repossession thereof by any
lessor thereof or third party having a lien thereon. Landlord shall also have
the right to remove from the premises (without the necessity of obtaining a
distress warrant, writ of sequestration or other legal process) all or any
portion of such furniture, fixtures, equipment and other property located
thereon and to place same in storage at any premises within the County in which
the premises is located; and in such event, Tenant shall be liable to Landlord
for costs incurred by Landlord in connection with such removal and storage.
Landlord shall also have the right to relinquish possession of all or any
portion of such furniture, fixtures, equipment and other property to any person
("Claimant") claiming to be entitled to possession thereof who presents to
Landlord a copy of any instrument represented to Landlord by Claimant to have
been executed by Tenant (or any predecessor Tenant) granting Claimant the right
under various circumstances to take possession of such furniture, fixtures,
equipment or other property, without the necessity on the part of Landlord to
inquire into the authenticity of said instrument's copy of Tenant's or Tenant's
predecessor's signature(s) thereon and without the necessity of Landlord making
any nature of investigation or inquiry as to the validity of the factual or
legal basis upon which Claimant purports to act; and Tenant agrees to indemnity
and hold Landlord harmless from all cost, expense, loss, damage and liability
incident to Landlord's relinquishment of possession of all or any portion of
such furniture, fixtures, equipment or other property to Claimant. The rights of
Landlord herein stated shall be in addition to any and all other rights which
Landlord has or may hereafter have at law or in equity; and Tenant stipulates
and agrees that the rights herein granted Landlord are commercially reasonable.

         L.       Notwithstanding anything in this lease to the contrary, all
amounts payable by Tenant to or on behalf of Landlord under this lease, whether
or not expressly denominated as rent, shall constitute rent for the purposes of
the Bankruptcy Code, 11 U.S.C. ss.502(b)(7).

         M.       This is a contract under which applicable law excuses Landlord
from accepting performance from or rendering performance to any person or entity
other than Tenant within the meaning of the Bankruptcy Code, 11 U.S.C.
ss.365(c), 365(e)(2).

         N.       If this Lease is assigned to any person or entity pursuant to
the provisions of the Bankruptcy Code, any and all monies or other
considerations payable or otherwise to be delivered in connection with such
assignment shall be paid or delivered to Landlord, shall be and remain the
exclusive property of Landlord and shall not constitute property of Tenant or of
the estate of Tenant within the meaning of the Bankruptcy Code. Any and all
monies or other considerations constituting Landlord's property under the
preceding sentence not paid or delivered to Landlord shall be held in trust for
the benefit of Landlord and be promptly paid or delivered to Landlord.

<PAGE>   15



         O.       Any person or entity to which this lease is assigned pursuant
to the provisions of the Bankruptcy Code, shall be deemed, without further act
or deed, to have assumed all of the obligations arising under this Lease on and
after the date of such assignment. Any such assignee shall upon demand execute
and deliver to Landlord an instrument confirming such assumption.

         19.      Omitted.

         20.      Mortgages. Tenant accepts this lease subject and subordinate
to any mortgage(s) and/or deed(s) of trust now or at any time hereafter
constituting a lien or charge upon the premises or the improvements situated
thereon, provided however, that if the mortgagee, trustee, or holder of any such
mortgage or deed of trust elects to have Tenant's interest in this lease
superior to any such instrument, then by notice to Tenant from such mortgagee,
trustee or holder, this lease shall be deemed superior to such lien, whether
this lease was executed before or after said mortgage or deed of trust. Tenant
shall at any time hereafter on demand execute any instruments, releases or other
documents which may be required by any mortgagee for the purpose of subjecting
and subordinating this lease to the lien of any such mortgage.

         21.      Landlord's Default. In the event Landlord should become in
default in any payments due on any such mortgage described in Paragraph 20
hereof or in the payment of taxes or any other items which might become a lien
upon the premises and which Tenant is not obligated to pay under the terms and
provisions of this lease, Tenant is authorized and empowered after giving
Landlord five (5) days prior written notice of such default and Landlord's
failure to cure such default, to pay any such items for and on behalf of
Landlord, and the amount of any item so paid by Tenant for or on behalf of
Landlord, together with any interest or penalty required to be paid in
connection therewith, shall be payable on demand by Landlord to Tenant; provided
however, that Tenant shall not be authorized and empowered to make any payment
under the terms of this Paragraph 21 unless the item paid shall be superior to
Tenant's interest hereunder. In the event Tenant pays any mortgage debt in full,
in accordance with this paragraph, it shall, at its election, be entitled to the
mortgage security by assignment or subrogation.

         22.      Mechanics Liens and Other Taxes.

         A.       Tenant shall have no authority, express or implied, to create
or place any lien or encumbrance of any kind or nature whatsoever upon, or in
any manner to bind the interests of Landlord in the premises or to charge the
rentals payable hereunder for any claim in favor of any person dealing with
Tenant, including those who may furnish materials or perform labor for any
construction or repairs, and each such claim shall affect and each such lien
shall attach to, if at all, only the leasehold interest granted to Tenant by
this instrument. Tenant covenants and agrees that it will pay or cause to be
paid all sums legally due and payable by it on account of any labor performed or
materials furnished in connection with any work performed on the premises on
which any lien is or can be validly and legally asserted against its leasehold
interest in the premises or the improvements thereon and that it will save and
hold Landlord harmless from any and all loss, cost or expense based on or
arising out of asserted claims or liens against the leasehold estate or against
the right, title and interest of the Landlord in the premises or under the terms
of this lease. Tenant

                                     - 15 -

agrees to give Landlord immediate written notice if any lien or encumbrance is
placed on the premises.

         B.       Tenant shall be liable for all taxes levied or assessed
against personal property, furniture or fixtures placed by Tenant in the
premises. If any such taxes for which Tenant is liable are levied or assessed
against Landlord or Landlord's property and if Landlord elects to pay the same
or if the assessed value of Landlord's property is increased by inclusion of
personal property, furniture or fixtures placed by Tenant in the premises, and
Landlord elects to pay the taxes based on such increase, Tenant shall pay to
Landlord upon demand that part of such taxes.

         23.      Omitted.

         24.      Certain Rights Reserved to Landlord. Landlord reserves and may
exercise the following rights without affecting Tenant's obligations hereunder:
(a) to change the name, street address, or suite numbers of the building; (b) to
install or maintain a sign or signs on the exterior of the building.

         25.      Notices. Each provision of this instrument or of any
applicable governmental laws, ordinances, regulations and other requirements
with reference to the sending, mailing or delivery of any notice or the making
of any payment by Landlord to Tenant or with reference to the sending, mailing
or delivery of any notice or the making of any payment by Tenant to Landlord
shall be deemed to be complied with when and if the following steps are taken:

         A.       All rent and other payments required to be made by Tenant to
Landlord hereunder shall be payable to Landlord at the address hereinbelow set
forth or at such other address as Landlord may specify from time to time by
written notice delivered in accordance herewith. Tenant's obligations to pay
rent and any other amounts to Landlord under the terms of this lease shall not
be deemed satisfied until such rent and other amounts have been actually
received by Landlord.

         B.       All payments required to be made by Landlord to Tenant
hereunder shall be payable to Tenant at the address hereinbelow set forth, or at
such other address within the continental United States as Tenant may specify

         26.      Hazardous Waste. The term "Hazardous Substances," as used in
this lease shall mean pollutants, contaminants, toxic or hazardous wastes, or
any other substances, the removal of which is required or the use of which is
restricted, prohibited or penalized by any "Environmental Law," which term shall

conducted on the premises that will produce any Hazardous Substance, except for
such activities that are part of the ordinary course of Tenant's business
activities that are part of the ordinary course of Tenant's business (the
"Permitted Activities") provided said Permitted Activities are conducted in

writing by Landlord; (ii) the premises will not be used in any manner for the

harmless from all claims, demands, actions, liabilities, costs, expenses,
damages and obligations of any nature arising from or as a result

                                     - 17 -

<PAGE>   18



of the use of the premises by Tenant. The foregoing indemnification shall
survive the termination or expiration of this lease.

         27.      Miscellaneous.

         A.       Words of any gender used in this lease shall be held and
construed to include any other gender, and words in the singular number shall be
held to include the plural, unless the context otherwise requires.

         B.       In the event the premises constitutes a portion of a multiple
occupancy building or building complex, Tenant's "proportionate share," as used
in this lease, shall mean a fraction, the numerator of which is the space
contained in the premises and the denominator of which is the entire space
contained in the building or building complex.

         C.       The terms, provisions and covenants and conditions contained
in this lease shall apply to, inure to the benefit of, and be binding upon the
parties hereto and upon their respective heirs, legal representatives,
successors and permitted assigns, except as otherwise herein expressly provided.
Landlord shall have the right to assign any of its rights and obligations under
this lease. Each party agrees to furnish to the other, promptly upon demand, a
corporate resolution, proof of due authorization by partners, or other
appropriate documentation evidencing the due authorization of such party to
enter into this lease.

         D.       The captions inserted in this lease are for convenience only
and in no way define, limit or otherwise describe the scope or intent of this
lease, or any provision hereof, or in any way affect the interpretation of this
lease.

         E.       Tenant agrees from time to time within ten (10) days after
request of Landlord, to deliver to Landlord, or Landlord's designee a
certificate of occupancy (if applicable) to an estoppel certificate stating that
this lease is in full force and effect, the date to which rent has been paid,
the unexpired term of this lease and such other matters pertaining to this lease
as may be requested by Landlord. It is understood and agreed that Tenant's
obligation to furnish such estoppel certificates in a timely fashion is a
material inducement for Landlord's execution of this lease.

         F.       This lease may not be altered, changed or amended except by an
instrument in writing signed by both parties hereto.

         G.       All obligations of Tenant hereunder not fully performed as of
the expiration or earlier termination of the term of this lease shall survive
the expiration or earlier termination of the term hereof, including without
limitation all payment obligations with respect to taxes and insurance and all
obligations concerning the condition of the premises. Upon the expiration or
earlier termination of the term hereof, and prior to Tenant vacating the
premises, Tenant shall pay to Landlord any amount reasonably as necessary to put
the premises, including without limitation all heating and air conditioning
systems and equipment therein, in good condition and repair. Tenant shall also,
prior to vacating the premises, pay to Landlord the amount of Tenant's
obligation hereunder for real estate

                                     - 18 -

<PAGE>   19



taxes and insurance premiums for the year in which the lease expires or
terminates. All such amounts shall be used and held by Landlord for payment of
such obligations of Tenant hereunder, with Tenant being liable for any
additional costs therefore upon demand by Landlord, or with any excess to be
returned to Tenant after all such obligations have been determined and
satisfied, as the case may be. Any security deposit held by Landlord shall be
credited against the amount payable by Tenant under this Subparagraph 27G.

         H.       If any clause or provision of this lease is illegal, invalid
or unenforceable under present or future laws effective during the term of this
lease, then and in that event, it is the intention of the parties hereto that
the remainder of this lease shall not be affected thereby, and it is also the
intention of the parties to this lease that in lieu of each clause or provision
of this lease that is illegal, invalid or unenforceable, there be added as a
part of this lease contract a clause or provision as similar in terms to such
illegal, invalid or unenforceable clause or provision as may be possible and be
legal, valid and enforceable.

         I.       Because the premises are on the open market and are presently
being shown, this lease shall be treated as an offer with the premises being
subject to prior lease and such offer subject to withdrawal or non-acceptance by
Landlord or to other use of the premises without notice, and this lease shall
not be valid or binding unless and until accepted by Landlord in writing and a
fully executed copy delivered to both parties hereto.

         J.       All references in this lease to "the date hereof" or similar
references shall be deemed to refer to the last date, in point of time, on which
all parties hereto have executed this lease.

         K.       Time is of the essence of this lease and all of its
provisions. This lease in all respect shall be governed by the laws of the State
of Georgia.

         L.       No animals shall be brought into or kept in or about the
building.

         M.       Tenant agrees to comply with subdivision regulations,
protective covenants, or other restrictions of record that are applicable to the
building or building complex.

         N.       The duties and obligations of Tenant herein shall be binding
upon all or any of them. The duties and obligations of Tenant shall run and
extend not only to the benefit of the Landlord, as named herein, but to the
following, at the option of the following or any of them (i) any person by,
through or under which Landlord derives the right to lease the premises; (ii)
the owner of the premises; and (ii) holders of mortgage or rent assignment
interests in the premises, as their respective interests may appear; provided,
however, nothing contained herein shall be construed to obligate Tenant to pay
rent to any person other than the Landlord until such time as Tenant has been
given written notice of either an exercise of a rent assignment or the
succession of some other party to the interests of Landlord.

                              ADDITIONAL PROVISIONS


       29. Tenant agrees to pay to Landlord rent for the premises, in advance,
without demand, deduction or set off, for the entire term hereof the following
base monthly rentals:

         (a)      For each of months one (1) through twelve (12) of the term of
         this lease: $12,486.00 per month.

         (b)      For each of months thirteen (13) through thirty-six (36) of
         the term of this lease: $26,013.00 per month.

         (c)      For each of moths thirty-seven (37) through forty-eight (48)
         of the term of this lease: $28,094.00 per month.

         (d)      For each of months forty-nine (49) through sixty (60) of the
         term of this lease: $29,134.00 per month.

       30. Tenant expressly agrees that the obligations incurred by Landlord
shall not constitute personal obligations of the officers, directors, trustees,
partners, joint venturers, members, stockholders, or other principals or
representatives of the Landlord. Tenant further agrees that it shall have
recourse against Landlord only to the extent of Landlord's assets for the
satisfaction of the obligations of the Landlord created under this Lease, and
not against the assets of such entity's officers, directors, trustees, partners,
joint venturers, members, stockholders, principals or representatives.

       31. Landlord covenants and agrees that if Tenant shall desert, vacate or
abandon the leased premises prior to the expiration or early termination of the
Lease Agreement, Landlord shall use reasonable efforts to lease the leased
premises to another Tenant.

       32. While this Lease is in full force and effect, provided Tenant is not
in default of the terms, covenants and conditions thereof, Tenant shall have the
sole right or option to extend the original term of this Lease Agreement for a
further consecutive term of twelve (12) months. Such extension or renewal of the
original term shall be on the same terms, covenants and conditions as provided
in the original term with the rent at the current rate at the time of option.
Notice of Tenant's intention to exercise this right or option must be given in
writing to Landlord on or before March 1, 1998, or the option contained in this
provision shall become null and void and of no effect. The right of option to
extend the original term of this Lease Agreement provided to Tenant herein shall
be for the exclusive benefit of the Tenant and shall terminate upon the
subletting of all or any part of the premises or assignment of this Lease.

       33. Notwithstanding any terms or provisions of this Lease which may be
construed to the contrary, Landlord and Tenant agree that Landlord will conduct
common area maintenance on the premises and grounds around the premises. Said
common area maintenance will include, but not


<PAGE>   22


ADDITIONAL PROVISIONS CONT.


be limited to, fire sprinkler water charges, irrigation, lawn maintenance,
security patrol and outside light maintenance. The cost of said common area
maintenance will be paid on a monthly basis by Tenant and will amount to
approximately EIGHT HUNDRED TWENTY-ONE AND NO/100 DOLLARS ($821.00) per month.
Landlord agrees that the monthly amount paid by Tenant shall be capped at a
compounded rate of ten percent (10%) per annum. However, in the event Landlord
elects to discontinue services or elects to provide additional services as may
be necessary under Paragraph 6 of this lease, the monthly common area
maintenance charge will be adjusted to reflect the change in services provided.

       34. Landlord hereby covenants and agrees to use reasonable efforts to
cause any holder of a deed to secure debt or mortgage now or at any time
hereafter constituting a lien or charge upon the premises or the improvements
situated thereon to enter into a non-disturbance agreement pursuant to which
such holder shall agree that if it shall acquire the ownership of the premises
or the improvements situated thereon through the exercise of a power of sale or
other remedy provided for in such deed to secure debt or mortgage, it shall
permit Tenant to remain in possession of the premises in accordance with the
terms and provisions of this lease, provided that Tenant shall continue to
perform its duties and obligations hereunder.

       35. Landlord and Tenant shall each provide the other with certificates
evidencing the issuance of all policies of insurance required to be maintained
by them under the terms and provisions of this Lease. Such certificates shall be
so provided prior to the commencement date and, thereafter, not less than
fifteen (15) days prior to the expiration date of such policies.

       36. Notwithstanding any terms or the provisions of this Lease Agreement
which may be construed to the contrary, and provided this Lease Agreement is in
full force and effect and Tenant is not in default of the terms, covenants, and
conditions thereof, Tenant shall have the sole right or option to cancel this
Lease Agreement at the end of the thirty-sixth (36th) month of the lease term
by: (1) providing Landlord with at least one hundred twenty (120) days of prior
written notice of its desire to cancel this Lease Agreement, and (2)
simultaneously depositing with Landlord a cancellation fee to be determined by
the following formula: [(5.85 x 49,444 x N/12)-(Total base rent paid by Tenant
through the cancellation month as provided in the rent schedule in Paragraph
29)]. N is equal to the number of months of Tenant's occupancy through the
cancellation month. For example, the penalty due at the end of the 36th month
shall be [(5.85 x 49,444 x 36/12)-(774,144)] or $102,373.00. Failure by Tenant
to provide said written notice and cancellation fee shall render this right or
option null and void, thus rendering this Lease Agreement in full force through
the original sixty (60) month lease term. The right of option to cancel this
Lease Agreement shall be for the exclusive benefit of the Tenant.

       37. Notwithstanding the provisions of Paragraph 7 hereof, Tenant shall
have the option to remove the following improvements from the premises by the
date of termination of this lease or upon earlier vacating of the premises
provided Tenant shall restore the premises to their original

condition with consideration for normal wear and tear. All such removals and
restoration shall be accomplished in a good workmanlike manner so as not to
damage the primary structure or structural qualities of the building and other
improvements situated on the premises:

                  magnetic lock sets, internal intercoms, electric lock sets,
                  etc.)

         (2)      Computer Room raised flooring.

         (3)      Liebert air conditioning units for Computer Room.

         (4)      Motor generator set.

                                 LEASE AGREEMENT

         THIS LEASE AGREEMENT, made and entered into by and between PEACHTREE
CROSSINGS BUSINESS PARK ASSOCIATES hereinafter referred to as "Landlord" and
HAYES MICROCOMPUTER PRODUCTS, INC., a Georgia corporation, hereinafter referred
to as "Tenant."

                                W I T N E S E T H

         1. Premises and Term. In consideration of the obligation of Tenant to
pay rent as herein provided, and in consideration of the other terms, provisions
and covenants hereof, Landlord hereby demises and leases to Tenant, and Tenant
hereby accepts and leases from landlord certain premises situated within the
County of Gwinnett, State of Georgia, more particularly described on Exhibit "A"
attached hereto and incorporated herein by reference, together with all rights,
privileges, easements, appurtenances, and immunities belonging to or in any way
pertaining to the premises and together with the buildings and other
improvements situated or to be situated upon said premises (said real property,
building and improvements being hereinafter referred to as the "premises.")

         TO HAVE AND TO HOLD the same for a term commencing on the "commencement
date," as hereinafter defined, and ending on the last day of the month that is
sixty (60) months after the commencement date.

         A. The "commencement date" shall be January 1, 1991, and ending
December 31, 1995. Tenant acknowledges that it has inspected and accepts the
premises, and specifically the buildings and improvements comprising the same,
in their present condition, as suitable for the purpose for which the premises
are leased. Taking of possession by Tenant shall be deemed conclusively to
establish that said buildings and other improvements are in good and
satisfactory condition as of when possession was taken. Tenant further
acknowledges that no representations as to the repair of the premises, nor
promises to alter, remodel or improve the premises have been made by Landlord,
unless such are expressly set forth in this lease. After the commencement date
the Tenant shall, upon demand, execute and deliver to Landlord a letter of
acceptance of delivery of the premises.

         B. Omitted.

         2. Base Rent and Security Deposit. See Additional Provision #29.

         A. Omitted.


<PAGE>   2

         B. In addition, Tenant has deposited with Landlord on the date hereof
the sum of ZERO AND NO/100 DOLLARS ($0), which sum shall be held by Landlord,
without obligation for interest, as security for the performance of Tenant's
covenants and obligations under this lease, it being expressly understood and
agreed that such deposit is not an advance rental deposit or a measure of
Landlord's damages in case of Tenant's default. Upon the occurrence of any event
of default by Tenant, Landlord may, from time to time, without prejudice to any
other remedy provided herein or provided by law, use such fund to the extent
necessary to make good any arrears of rent or other payments due Landlord
hereunder, and any other damage, injury, expense or liability caused by such
event of default, and Tenant shall pay to Landlord on demand the amount so
applied in order to restore the security deposit to its original amount.
Although the security deposit shall be deemed the property of Landlord, any
remaining balance of such deposit shall be returned by Landlord to Tenant at
such time after termination of this lease that all of Tenant's obligations under
this lease have been fulfilled.

         3. Use. The demised premises shall be used only for the purpose of
general office, receiving, storing, manufacturing, repairing, shipping and
selling (other than retail) products, materials and merchandise made and/or
distributed by Tenant and for such other lawful purposes as may be incidental
thereto, and subject to any building or building complex rules and regulations
which shall not impair Tenant's use of the premises. Outside storage, including
without limitation, trucks and other vehicles, is prohibited without Landlord's
prior written consent. Tenant shall at its own cost and expense obtain any and
all licenses and permits necessary for any such use. Tenant shall comply with
all governmental laws, ordinances and regulations applicable to the use of the
premises, and shall promptly comply with all governmental orders and directives
for the correction, prevention and abatement of nuisances in or upon, or
connected with the premises, all at Tenant's sole expense. Tenant shall not
permit any objectionable or unpleasant odors, smoke, dust, gas, noise or
vibrations to emanate from the premises, nor take any other action which would
constitute a nuisance or would disturb or endanger any other tenants of the
building in which their premises are situated or unreasonably interfere with
their use of their respective premises. Without Landlord's prior written
consent, Tenant shall not receive, store or otherwise handle any product,
material or merchandise which is explosive or highly flammable. Tenant will not
permit the premises to be used for any purpose or in any manner, including,
without limitation, any method of storage which would render the insurance
thereon void or the insurance risk more hazardous or cause the State Board of
insurance or other insurance authority to disallow any sprinkler credits. If any
increase in the fire and extended coverage insurance premiums paid by Landlord
or other tenants for the building in which Tenant occupies space is caused by
Tenant's use and occupancy of the premises, or if Tenant vacates the premises
and causes an increase in such premiums, then Tenant shall pay as additional
rental the amount of such increase to Landlord.

         Tenant agrees that the point pressure resulting from Tenant's racking
system, inventory, forklifts and equipment pertaining to Tenant's use of the
premises shall not exceed allowable design floor loading for floor slabs on
grade. Tenant shall hold harmless Landlord from any loss, liability, and
expenses, both real and alleged, arising out of such damage or repair caused by
Tenant's negligence or failure to comply with this paragraph.


                                      -2-

         4. Taxes.

         A. Landlord agrees to pay before they become delinquent all taxes,
assessments and governmental charges of any kind and nature whatsoever
thereinafter collectively referred to as "taxes" lawfully levied or assessed
against the building and the grounds, parking areas, driveways and alleys around
the building; provided, however, that the maximum amount of taxes to be paid by
Landlord hereunder during any one real estate tax year shall be ZERO AND NO/100
DOLLARS ($0.00). If in any real estate tax year during the term hereof or any
renewal or extension the taxes levied or assessed against the building and the
grounds, parking areas, driveways and alleys around the building during such tax
year shall exceed the sum set forth in the preceding sentence, Tenant shall pay
to Landlord as additional rental, upon demand, the amount of such excess. In the
event any such amount is not paid within twenty (20) days after the date of
Landlord's invoice to Tenant, the unpaid amount shall bear interest at the rate
of twenty (20%) percent per annum from the date of such invoice until payment by
Tenant. In the event the premises constitute a portion of a multiple occupancy
building, Tenant agrees to pay to Landlord as additional rental, upon demand,
the amount of Tenant's "proportionate share" (as defined in subparagraph 27B) of
the excess taxes referred to in this subparagraph above.

         B. If at any time during the term of this lease, the present method of
taxation shall be changed so that in lieu of the whole or any part of any taxes,
assessments, or governmental charges levied, assessed or imposed on real estate
and the improvements thereon, there shall be levied, assessed or imposed on
Landlord a capital levy or other tax directly on the rents received therefrom
and/or a franchise tax, assessment, levy or charge measured by or based, in
whole or in part, upon such rents for the present or any future building or
buildings on the premises, then all such taxes, assessments, levies or charges,
or the part thereof so measured or based shall be deemed to be included within
the term "taxes" for the purposes hereof.

         C. The Landlord shall have the right to engage a tax consulting firm to
attempt to assure a fair tax burden for the building and grounds within the
applicable taxing jurisdiction. Tenant shall pay to Landlord upon demand, from
time to time, as additional rent, the amount of Tenant's proportionate share of
the cost of such service.

         D. Any payment to be made pursuant to this Paragraph 4 with respect to
the real estate tax year in which this lease commences or terminates shall be
prorated.

         5. Landlord's Repairs and Obligations. Landlord shall at his expense
maintain only the roof, foundation and the structural soundness of the exterior
walls of the building in good repair, reasonable wear and tear excepted. Tenant
shall repair and pay for any damage caused by the negligence of Tenant, or
Tenant's employees, agents or invitees, or caused by Tenant's default hereunder.
The term "walls' as used herein shall not include windows, glass or plate glass,
doors, store fronts or office entries. Tenant shall immediately give Landlord
written notice of defect or need for repairs, after which Landlord shall have
reasonable opportunity to repair same or cure such defect. Landlord's liability
with respect to any defects, repairs or maintenance for which Landlord 

                                      -3-
<PAGE>   4


is responsible under any of the provisions of this lease shall be limited to the
cost of such repairs or maintenance or the curing of such defect.

         6. Tenant's Repairs and Obligations.

         A. Tenant shall at its own cost and expense keep and maintain all parts
of the premises (except those for which Landlord is expressly responsible under
the terms of this lease) in good condition, promptly making all necessary
repairs, repainting, and replacements, including but not limited to, windows,
glass and plate glass, doors, any office entries, interior walls and finish
work, floors and floor covering, downspouts, gutters, heating and air
conditioning systems, dock boards, truck doors, dock bumpers, paving, plumbing
work and fixtures, termites and pest extermination, regular removal of trash and
debris, grounds maintenance, common sewage line plumbing, common exterior
lighting (if applicable), common dumpster removal (if applicable) and other
obligations of the building, including, but not limited to, keeping the parking
areas, driveways, alleys and the whole of the premises in a clean and sanitary
condition. Tenant shall not be obligated to repair any damage caused by fire,
tornado or other casualty covered by the insurance to be maintained by Landlord
pursuant to subparagraph 12A below, except that Tenant shall be obligated to
repair all wind damage to glass except with respect to tornado or hurricane
damage.

         B. The cost of maintenance and repair of any common party walls (any
wall, divider, partition or any other structure separating the premises from any
adjacent premises) shall be shared equally by Tenant and the tenant or tenants
occupying adjacent premises. Tenant shall not damage any demising wall or
disturb the integrity and support provided by any demising wall and shall, at
its sole cost and expense, promptly repair any damage or injury to any demising
wall caused by Tenant or its employees, agents or invitees.

         C. In the event the premises constitute a portion of a multiple
occupancy building, Tenant and its employees, customers and licensees shall have
the exclusive right to use the parking areas, if any, as may be designated by
Landlord in writing, subject to such reasonable rules and regulations as
Landlord may from time to time prescribe and subject to rights of ingress and
egress of other tenants. Landlord shall not be responsible for enforcing
Tenant's exclusive parking rights against any third parties. Parking spaces have
been provided in accordance with applicable local building codes and anticipated
needs of tenants. Tenant agrees not to use more than its proportionate share as
so provided.

         D. Landlord reserves the right to perform and provide all of Tenant's
repairs and obligations under subparagraph 6A above, and Tenant shall, in lieu
of the obligations set forth under subparagraph 6A above with respect to such
items, pay monthly as additional rent due under Paragraph 2A for its
proportionate share of the cost and expense, including overhead, for those
items; provided, however, that Landlord shall have the right to require Tenant
to pay such other reasonable proportions of said repairs and obligations as may
be determined by Landlord in its sole discretion; and further provided that if
Tenant or any other particular tenant of the building can be clearly identified
as being responsible for obstructions or stoppage of the common sanitary sewage 

                                      -4-
<PAGE>   5

line, then Tenant, if Tenant is responsible, shall pay the entire cost thereof,
upon demand, as additional rent.

         E. Omitted.

         F. Tenant shall, at its own cost and expense, enter into a regularly
scheduled preventive maintenance/service contract with a maintenance contractor
and the contract must be approved by Landlord. The service contract must include
all services suggested by the equipment manufacturer within the
operation/maintenance manual and must become effective (and a copy thereof
delivered to Landlord) within thirty (30) days of the date Tenant takes
possession of the premises.

         7. Alterations. Tenant shall not make any alterations, additions or
improvements to the premises (including, but not limited to, roof and wall
penetrations) without the prior written consent of Landlord. Such consent will
not be denied provided the improvements are building standard office/warehouse
finishes. In the event Landlord consents to the making of any such alterations,
additions or improvements by Tenant, the same shall be made by Tenant, at
Tenant's sole cost and expense, in accordance with all applicable laws,
ordinances and regulations, and all requirements of Landlord's and Tenant's
insurance policies and only in accordance with plans and specifications approved
by Landlord; and any contractor or person selected by Tenant to make the same
and all subcontractors must first be approved in writing by Landlord. Tenant
may, without the consent of Landlord, but at its own cost and expense and in a
good workmanlike manner erect such shelves, bins, machinery and trade fixtures
as it may deem advisable, without altering the basic character of the building
or improvements and without overloading or damaging such building or
improvements, and in each case complying with all applicable governmental laws,
ordinances, regulations and other requirements. All alterations, additions,
improvements and partitions erected by Tenant shall be and remain the property
of Tenant during the term of this lease and Tenant shall, unless Landlord
otherwise elects as hereinafter provided, remove all alterations, additions,
improvements and partitions erected by Tenant and restore the premises to their
original condition by the date of termination of this lease or upon earlier
vacating of the premises; provided, however, that if Landlord so elects prior to
termination of this lease or upon earlier vacating of the premises, such
alterations, additions, improvements and partitions shall become the property of
Landlord as of the date of termination of this lease or upon earlier vacating of
the premises and shall be delivered up to the Landlord with the premises. All
shelves, bins, machinery and trade fixtures installed by Tenant may be removed
by Tenant prior to the termination of this lease if Tenant so elects, and shall
be removed by the date of termination of this lease or upon earlier vacating of
the premises if required by Landlord; upon any such removal Tenant shall restore
the premises to their original condition with consideration for normal wear and
tear. All such removals and restoration shall be accomplished in a good
workmanlike manner so as not to damage the primary structure or structural
qualities of the building and other improvements situated on the premises.

         8. Signs. Tenant agrees to conform to Landlord's signage program for
the building; however, all costs and expense of the sign, sign installation,
removal and repair shall be paid by Tenant. Tenant shall only have the right to
install standard signs upon the premises where first approved in writing by
Landlord and subject to any applicable governmental laws, ordinances,



                                      -5-
<PAGE>   6

regulations and other requirements. Tenant shall remove all signs prior to the
termination of this lease. Such installations and removals shall be made in such
a manner as to avoid injury or defacement of the building and other
improvements, and Tenant shall repair any injury or defacement, including,
without limitation, discoloration caused by installation and/or removal.

         9.  Inspection and Right of Entry. Landlord and Landlord's agents and
representatives shall have the right to enter the premises at any time in the
event of an emergency and to enter and inspect the premises at any reasonable
time during business hours, for the purpose of ascertaining the condition of the
premises in order to make such repairs as may be required or permitted to be
made by Landlord under the terms of this lease. During the period that is six
(6) months prior to the end of the term hereof, Landlord and Landlord's agents
and representatives shall have the right to enter the premises at any reasonable
time during business hours for the purpose of showing the premises and shall
have the right to erect on the premises a suitable sign indicating the premises
are available. Tenant shall arrange to meet with Landlord for a joint inspection
of the premises prior to vacating. In the event of Tenant's failure to arrange
such joint inspection, Landlord's inspection at or after Tenant's vacating the
premises shall be conclusively deemed correct for purposes of determining
Tenant's responsibility for repairs and restoration.

         10. Utilities. Landlord agrees to provide at its cost water,
electricity and gas (when applicable) service connections into the premises; but
Tenant shall pay for all water, gas, heat, light, power, telephone, sewer,
sprinkler charges and other utilities and services used on or from the premises,
together with any taxes, penalties, surcharges or the like pertaining thereto
and any maintenance charges for utilities and shall furnish all electric light
bulbs and tubes. If any such services are not separately metered to Tenant,
Tenant shall pay a reasonable proportion as determined by Landlord of all
charges jointly metered with other premises, provided, however, Landlord shall
have the right to require Tenant to pay such other reasonable proportion of said
jointly metered charges as may be determined by Landlord in its sole discretion.
Landlord shall in no event by liable for any interruption or failure of utility
services on the premises.

         11. Assignment and Subletting.

         A.  Tenant shall not have the right to assign, sublet, transfer or
encumber this lease, or any interest therein, without the prior written consent
of Landlord. Any attempted assignment, subletting, transfer or encumbrance by
Tenant in violation of the terms and covenants of this Paragraph shall be void.
All cash or other proceeds of any assignment, such proceeds as exceed the
rentals called for hereunder in the case of a subletting and all cash or other
proceeds of any other transfer of Tenant's interest in this lease shall be paid
to Landlord, whether such assignment, subletting or other transfer is consented
to by Landlord or not, unless Landlord agrees to the contrary in writing, and
Tenant hereby assigns all rights it might have or ever acquire in any such
proceeds to Landlord. Any assignment, subletting or other transfer of Tenant's
interest in this lease shall be for an amount equal to the then fair market
value of such interest. These covenants shall run with the land and shall bind
Tenant and Tenant's heirs, executors, administrators, personal representatives,
representatives in any bankruptcy proceeding, successors and assigns. any
assignee, sublessee or transferee of Tenant's interest in this lease (all such
assignees, sublessees and


                                      -6-
<PAGE>   7


transferees being hereinafter referred to as "successors"), by assuming Tenant's
obligations hereunder shall assume liability to Landlord for all amounts paid to
persons other than Landlord by such successors in contravention of this
Paragraph. No assignments, subletting or other transfer, whether consented to by
Landlord or not, shall relieve Tenant of its liability hereunder. Upon the
occurrence of an "event of default" as hereinafter defined, if the premises or
any part thereof are then assigned or sublet, Landlord, in addition to any other
remedies herein provided, or provided by law, may at its option collect directly
form such assignee or subtenant all rents becoming due to Tenant under such
assignment or sublease and apply such rent against any sums due to Landlord from
Tenant hereunder, and no such collection shall be construed to constitute a
novation or a release of Tenant from the further performance of Tenant's
obligations hereunder.

         B.  If this lease is assigned to any person or entity pursuant to the
provisions of the Bankruptcy Code 11 U.S.C. ss. 101, et seq. (the "Bankruptcy
Code"), any and all monies or other considerations payable or otherwise to be
delivered in connection with such assignment shall be paid or delivered to
Landlord, shall be and remain the exclusive property of Landlord and shall not
constitute property of Tenant or of the estate of Tenant within the meaning of
the Bankruptcy Code. Any and all monies or other considerations constituting
Landlord's property under the preceding sentence not paid or delivered to
Landlord shall be held in trust for the benefit of the Landlord and promptly
paid or delivered to Landlord.

         C.  Any person or entity to which this lease is assigned pursuant to 
the provisions of the Bankruptcy Code, shall be deemed, without further act or
deed, to have assumed all of the obligations arising under this lease on and
after the date of such assignment. Any such assignee shall upon demand execute
and deliver to Landlord an instrument confirming such assumption.

         12. Fire and Casualty Damage.

         A.  Landlord agrees to maintain insurance covering the building of
which the premises are a part (including building standard office/warehouse
finishes which are constructed by Tenant) in an amount not less than eighty
percent (80%) (or such greater percentage as may be necessary to comply with the
provisions of any co-insurance clauses of the policy) of the replacement costs
thereof, insuring against the perils of Fire, Lightning, Extended Coverage,
Vandalism and Malicious Mischief, extended by Special Extended Coverage
Endorsement to insure against all other regulatory authority for the state in
which the premises are situated for use by insurance companies admitted in such
state for the writing of such insurance on risks located within such state.
Subject to the provisions of subparagraphs 12C, 12D and 12E below, such
insurance shall be for the sole benefit of Landlord and under its sole control.
If, during the second calendar year after the commencement date of this lease,
or during any subsequent calendar year of the primary term or any renewal or
extension, Landlord's cost of maintaining such insurance shall exceed Landlord's
cost of maintaining such insurance for the first calendar year or the term
hereof, Tenant agrees to pay to Landlord, as additional rental, the amount of
such excess not to exceed $2,425.00 per year (or in the event the premises
constitute a portion of a multiple occupancy building, Tenant's full
proportionate share of such excess). The first calendar year shall be the year
in which the lease commences. Said payments shall be made to Landlord within ten
(10) days after presentation to Tenant of Landlord's

statement setting forth the amount due. Any payment to be made pursuant to this
subparagraph A with respect to the year in which this lease commences or
terminates shall bear the same ratio to the payment which would be required to
be made for the full year as the part of such year covered by the term of this
lease bears to a full year.

         B. If the buildings situated upon the premises should be damaged or
destroyed by fire, tornado or other casualty, Tenant shall give immediate
written notice thereof to Landlord.

         C. If the buildings situated upon the premises should be totally
destroyed by fire, tornado or other casualty, or if they should be so damaged
thereby that rebuilding or repairs cannot in Landlord's reasonable estimation be
completed within one hundred twenty (120) days after the date upon which
Landlord is notified by Tenant of such damage, this lease shall terminate and
the rent shall be abated during the unexpired portion of this lease, effective
upon the date of the occurrence of such damage.

         D. If the buildings situated upon the premises should be damaged by any
peril covered by the insurance to be provided by Landlord under subparagraph 12A
above, but only to such extent that rebuilding or repairs can in Landlord's
reasonable estimation be completed within one hundred twenty (120) days after
the date upon which Landlord is notified by Tenant of such damage, this lease
shall not terminate, and Landlord shall at its sole cost and expense thereupon
proceed with reasonable diligence to rebuild and repair such buildings to
substantially the condition in which they existed prior to such damage, except
that Landlord shall not be required to rebuild, repair or replace any part of
the partitions, fixtures, additions and other improvements which may have been
placed in, on or about the premises by Tenant and except that Landlord may elect
not to rebuild if such damage occurs during the last year of the term of the
lease exclusive of any option which is unexercised at the time of such damage.
If the premises are untenantable in whole or in part following such damage, the
rent payable hereunder during the period in which they are untenantable shall be
reduced to such extent as may be fair and reasonable under all of the
circumstances. In the event that Landlord should fail to complete such repairs
and rebuilding within one hundred twenty (120) days after the date upon which
Landlord is notified by Tenant of such damage, Tenant may at its option
terminate this lease by delivering written notice of termination to Landlord as
Tenant's exclusive remedy, whereupon all rights and obligations hereunder shall
cease and terminate.

         E. Notwithstanding anything herein to the contrary, in the event the
holder of any indebtedness secured by a mortgage or deed of trust covering the
premises requires that the insurance proceeds be applied to such indebtedness,
then Landlord shall have the right to terminate this lease by delivering written
notice of termination to Tenant within fifteen (15) days after such requirement
is made by any such holder, whereupon all rights and obligations hereunder shall
cease and terminate.

         F. Each of Landlord and Tenant hereby releases the other from any loss
or damage to property caused by fire or any other perils insured in policies of
insurance covering such property, even if such loss or damage shall have been
caused by the fault or negligence of the other party, or anyone for whom such
other party may be responsible. Each of the Landlord and Tenant agrees that


                                      -8-
<PAGE>   9

it will request its insurance carriers to include in its policies such a clause
or endorsement. If extra cost shall be charged therefore, each party shall
advise the other thereof and of the amount of the extra cost, and the other
party, at its election, may pay the same, but it shall not be obligated to do
so.

         13. Liability. Landlord shall not be liable to Tenant or Tenant's
employees, agents, patrons or visitors, or to any other person whomsoever, for
any injury to person or damage to property on or about the premises, resulting
from and or caused in part or whole by the negligence or misconduct of Tenant,
its agents, servants or employee or any other person entering upon the premises,
or caused by the buildings and improvements located on the premises becoming out
of repair, or caused by leakage of gas, oil, water or steam or by electricity
emanating from the premises, or due to any cause whatsoever, and Tenant hereby
covenants and agrees that it will at all times indemnify and hold safe and
harmless the property, the Landlord (including without limitation the trustee
and beneficiaries if Landlord is a trust). landlord's agents and employees from
any loss, liability, claims, suits, costs, expenses, including without
limitation attorney's fees and damages, both real and alleged, arising out of
any such damage or injury, except injury to persons or damage to property the
cause of which is the negligence of Landlord or the failure of Landlord to
repair any part of the premises which Landlord is obligated to repair and
maintain hereunder within a reasonable time after the receipt of written notice
from Tenant of needed repairs. Tenant shall procure and maintain throughout the
term of this lease a policy or policies of insurance, at its sole cost and
expense, insuring both Landlord and Tenant against all claims, demands or
actions arising out of or in connection with: (i) the premises; (ii) the
condition of the premises; (iii) Tenant operations in and maintenance and use of
the premises; and (iv) Tenant's liability assumed under this lease, the limits
of such policy or policies to be in the amount of not less than $1,000,000.00
per occurrence in respect to injury to persons (including death), and in the
amount of not less than $100,000 per occurrence in respect to property damage or
destruction, including loss of use thereof. All such policies shall be procured
by Tenant from responsible insurance companies satisfactory to Landlord.
Certificates evidencing such policies, together with receipt evidencing payment
of premiums therefor, shall be delivered to Landlord prior to the commencement
date of this lease. Not less than fifteen (15) days prior to the expiration date
of any such policies, certificates evidencing the renewals thereof (bearing
notations evidencing the payment of renewal premiums) shall be delivered to
Landlord. Such policies shall further provide that not less than thirty (30)
days written notice shall be given to Landlord before such policy may be
cancelled or changed to reduce insurance provided thereby.

         14. Condemnation.

         A.  If the whole or any substantial part of the premises should be 
taken for any public or quasi-public use under governmental law, ordinance or
regulation, or by right of eminent domain, or by private purchase in lieu
thereof and the taking would prevent or materially interfere with the use of the
premises for the purposes for which they are being used, this lease shall
terminate and the rent shall be abated during the unexpired portion of this
lease, effective when the physical taking of said premises shall occur.


                                      -9-
<PAGE>   10


         B.  If part of the premises shall be taken for any public or
quasi-public use under any governmental law, ordinance or regulation, or by
right of eminent domain, or by private purchase in lieu thereof, and this lease
is not terminated as provided in the subparagraph above, this lease shall not
terminate but the rent payable hereunder during the unexpired portion of this
lease shall be reduced to such extent as may be fair and reasonable under all of
the circumstances.

         C.  All compensation awarded for any taking (or the proceeds of private
sale in lieu thereof) of the premises, buildings or other improvements, or any
part thereof, shall be the property of Landlord and Tenant hereby assigns its
interest in any such award to Landlord; provided, however, Landlord shall have
no interest in any award made to Tenant for loss of business or for the taking
of Tenant's fixtures and improvements if a separate award for such items is made
to Tenant.

         15. Holding Over. Tenant will, at the termination of this lease by
lapse of time or otherwise, yield up immediate possession to Landlord with all
repairs and maintenance required herein to be performed by Tenant completed. If
Landlord agrees in writing that Tenant may hold over after the expiration or
termination of this lease, unless the parties hereto otherwise agree in writing
on the terms of such holding over, the hold over tenancy shall be subject to
termination by Landlord at any time upon not less than five (5) days advance
written notice, or by Tenant at any time upon not less than thirty (30) days
advance written notice, and all of the other terms and provisions of this lease
shall be applicable during that period, except that Tenant shall pay Landlord
from time to time upon demand, as rental for the period of any hold over, an
amount equal to double the rent in effect on the termination date, computed on a
daily basis for each day of the hold over period. No holding over by Tenant,
whether with or without consent of Landlord, shall operate to extend this lease
except as otherwise expressly provided. The preceding provisions of this
paragraph 15 shall not be construed as consent for Tenant to hold over.

         16. Quiet Enjoyment. Landlord covenants that it now has good title to
the premises, free and clear of all liens and encumbrances, excepting only the
lien for current taxes not yet due, such mortgage or mortgages as are permitted
by the terms of this lease, zoning ordinances and other building and fire
ordinances and governmental regulations relating to the use of such property,
and easements, restrictions and other conditions of record. Landlord represents
and warrants that it has full right and authority to enter into this lease and
that Tenant, upon paying the rental herein set forth and performing its other
covenants and agreements herein set forth, shall peaceably and quietly have,
hold and enjoy the premises for the term hereof without hindrance or molestation
from Landlord, subject to the terms and provisions of this lease.

         17. Events of Default. The following events shall be deemed to be
events of default by Tenant under this lease:

         A.  Tenant shall fail to pay any installment of the rent herein 
reserved when due, or any other payment or reimbursement to Landlord required
herein when due, and such failure shall continue for a period of ten (10) days
from the date such payment was due.


                                      -10-
<PAGE>   11


         B.  Tenant or any guarantor of Tenant's obligations hereunder shall
generally not pay its debts as they become due or shall admit in writing its
inability to pay its debts or shall make a general assignment for the benefit of
creditors, or Tenant or any such guarantor shall commence any case, proceeding
or other action seeking to have an order for relief entered on its behalf as a
debtor or to adjudicate it as bankrupt or insolvent, or seeking reorganization,
arrangement, adjustment, liquidation, dissolution, or composition of it or its
debts under any law relating to bankruptcy, insolvency, reorganization or relief
of debtors or seeking appointment of a receiver, trustee, custodian or other
similar official for it or for all or of any substantial part of its property,
or Tenant or any such guarantor shall take any action to authorize or in
contemplation of any of the actions set forth above in this paragraph, or

         C.  Any case, proceeding or other action against Tenant or any 
guarantor of Tenant's obligations hereunder shall be commenced seeking to have
an order for relief entered against it as debtor or to adjudicate it as bankrupt
or insolvent, or seeking reorganization, arrangement, adjustment, liquidation,
dissolution or composition of it or its debts under any law relating to
bankruptcy, insolvency, reorganization or relief of debtors, or seeking
appointment of a receiver, trustee, custodian or other similar official for it
or for all or any substantial part of its property.

         D.  A receiver to trustee shall be appointed for all or substantially
all of the assets of Tenant.

         E.  Tenant shall desert or vacate any substantial portion of the
premises.

         F.  Tenant shall fail to discharge any lien placed upon the premises in
violation of Paragraph 22 hereof within twenty (20) days after any such lien or
encumbrance is filed against the premises.

         G.  Tenant shall fail to comply with any term, provision or covenant of
this lease (other than the foregoing in this Paragraph 17), and shall not cure
or commence to cure and diligently pursue to completion such failure within
twenty (20) days after written notice thereof to Tenant.

         H.  Tenant shall fail to continuously operate its business at the
premises for the permitted use set forth in Paragraph 3 whether or not Tenant is
in default of the rental payments due under this lease.

         18. Remedies.

         A.  Upon the occurrence of any of such events of default described in
Paragraph 17 hereof, Landlord shall have the option to pursue any one or more of
the following remedies without any notice or demand whatsoever:

            (1)         Terminate this lease, in which event Tenant shall
                        immediately surrender the premises to Landlord, and if
                        Tenant fails so to do, Landlord may, without prejudice
                        to any other remedy which it may have for possession or
                        arrearage 



                                      -11-
<PAGE>   12

                        in rent, enter upon and take possession of the premises 
                        and expel or remove Tenant and any other person who may 
                        be occupying such premises or any part thereof, by force
                        it necessary, without being liable for prosecution or 
                        any claim of damage therefore.

            (2)         Enter upon and take possession of the premises and expel
                        or remove Tenant and any other person who may be
                        occupying such premises or any part thereof, by force if
                        necessary, without being liable for prosecution or any
                        claim for damages therefore.

            (3)         Enter upon the Premises, by force if necessary, without
                        being liable for prosecution or any claim for damages
                        therefore, and do whatever Tenant is obligated to do
                        under the terms of this lease; and Tenant agrees to
                        reimburse Landlord on demand for any expenses which
                        Landlord may incur in thus effecting the compliance with
                        Tenant's obligations under this Lease, and Tenant
                        further agrees that Landlord shall not be liable for any
                        damages resulting to the Tenant from such action,
                        whether caused by the negligence of Landlord or
                        otherwise.

            (4)         Alter all locks and other security devices at the
                        premises without terminating this lease.

         B. In the event Landlord may elect to regain possession of the premises
by a forcible detainer proceeding, Tenant hereby specifically waives any
statutory notice which may be required prior to such proceeding, and agrees that
Landlord's execution of this lease is, in part, consideration of this waiver.

         C. In the event Tenant fails to pay any installment of rent hereunder
as and when such installment is due, to help defray the additional cost to
Landlord for processing such late payments Tenant shall pay to Landlord on
demand a late charge in an amount equal to five (5%) percent of such
installment; and the failure to pay such amount within five (5) days after
demand therefore shall be an event of default hereunder. The provision for such
late charge shall be in addition to all of Landlord's other rights and remedies
hereunder or at law and shall not be construed as liquidated damages or as
limiting Landlord's remedies in any manner.

         D. In the event Tenant's check, given to Landlord in payment, is
returned by the bank for non-payment, Tenant agrees to pay all expenses incurred
by Landlord as a result thereof.

         E. Exercise by Landlord of any one or more remedies hereunder granted
or otherwise available shall not be deemed to be an acceptance or surrender of
the premises by Tenant, whether by agreement or by operation of law, it being
understood that such surrender can be effected only by the written agreement of
Landlord and Tenant. No such alteration of locks or other security devices and
no removal or other exercise of dominion by Landlord over the property of Tenant
or others at the premises shall be deemed unauthorized or constitute a
conversion, Tenant hereby 


                                      -12-
<PAGE>   13


consenting, after any event of default, to the aforesaid exercise of dominion
over Tenant's property within the premises. All claims for damages by reason of
such re-entry and/or repossession and/or alteration of locks or other security
devices are hereby waived, as are all claims for damages by reason of any
distress warrant, forcible detainer proceedings, sequestration proceedings or
other legal process. Tenant agrees that any re-entry by Landlord may be pursuant
to judgment obtained in forcible detainer proceedings or other legal proceedings
or without the necessity for any legal proceedings, as Landlord may elect, and
Landlord shall not be liable for trespass or otherwise.

         F. Omitted.

         G. In the event that Landlord elects to repossess the premises without
terminating the lease, or in the event Landlord elects to terminate the lease,
then Tenant, at Landlord's option, shall be liable for and shall pay to
Landlord, at the address specified for notice to Landlord herein, all rental and
other indebtedness accrued to the date of such repossession, plus rental
required to be paid by Tenant to Landlord during the remainder of the lease term
until the date of expiration of the term as stated in Paragraph 1 diminished by
any net sums thereafter received by Landlord through reletting the premises
during said period (after deducting expenses incurred by Landlord as provided in
subparagraph 18H below). In no event shall Tenant be entitled to any excess of
any rental obtained by reletting over and above the rental herein reserved.
Actions to collect amounts due by Tenant to Landlord under this subparagraph may
be brought from time to time, on one or more occasions, without the necessity of
Landlord's waiting until expiration of the lease term.

         H. In case of any event of default or breach by Tenant, or threatened
or anticipatory breach or default, Tenant shall also be liable for and shall pay
to Landlord, at the address specified for notice to Landlord herein, in addition
to any sum provided to be paid above, brokers' fees incurred by Landlord in
connection with reletting the whole or any part of the premises; the costs of
removing and storing Tenant's or other occupant's property; the costs of
repairing, altering, remodeling or otherwise putting the premises into condition
acceptable to a new tenant or tenants, and all reasonable expenses incurred by
Landlord in enforcing or defending Landlord's rights and/or remedies including
reasonable attorney's fees.

         I. In the event of termination or repossession of the premises for an
event of default, Landlord shall not have any obligation to relet or to attempt
to relet the premises, or any portion thereof; and in the event of reletting,
Landlord may relet the whole or any portion of the premises for any period to
any tenant and for any use and purpose.

         J. If Tenant should fail to make any payment or cure any default
hereunder within the time herein permitted, Landlord, without being under any
obligation to do so and without thereby waiving such default, may make such
payment and/or remedy such other default for the account of Tenant (and enter
the premises for such purpose), and thereupon Tenant shall be obligated to, and
hereby agrees, to pay Landlord upon demand, all costs, expenses and
disbursements (including reasonable attorney's fees) incurred by Landlord in
taking such remedial action.


                                      -13-
<PAGE>   14


         K. In the event that Landlord shall have taken possession of the
premises pursuant to the authority herein granted then Landlord shall have the
right to keep in place and use all of the furniture, fixtures and equipment at
the premises, including that which is owned by or leased to Tenant at all times
prior to any foreclosure thereon by Landlord or repossession thereof by any
lessor thereof or third party having a lien thereon. Landlord shall also have
the right to remove from the premises (without the necessity of obtaining a
distress warrant, writ of sequestration or other legal process) all or any
portion of such furniture, fixtures, equipment and other property located
thereon and to place same in storage at any premises within the County in which
the premises is located; and in such event, Tenant shall be liable to Landlord
for costs incurred by Landlord in connection with such removal and storage.
Landlord shall also have the right to relinquish possession of all or any
portion of such furniture, fixtures, equipment and other property to any person
("Claimant") claiming to be entitled to possession thereof who presents to
Landlord a copy of any instrument represented to Landlord by Claimant to have
been executed by Tenant (or any predecessor Tenant) granting Claimant the right
under various circumstances to take possession of such furniture, fixtures,
equipment or other property, without the necessity on the part of Landlord to
inquire into the authenticity of said instrument's copy of Tenant's or Tenant's
predecessor's signature(s) thereon and without the necessity of Landlord making
any nature of investigation or inquiry as to the validity of the factual or
legal basis upon which Claimant purports to act; and Tenant agrees to indemnity
and hold Landlord harmless from all cost, expense, loss, damage and liability
incident to Landlord's relinquishment of possession of all or any portion of
such furniture, fixtures, equipment or other property to Claimant. The rights of
Landlord herein stated shall be in addition to any and all other rights which
Landlord has or may hereafter have at law or in equity; and Tenant stipulates
and agrees that the rights herein granted Landlord are commercially reasonable.

         L. Notwithstanding anything in this lease to the contrary, all amounts
payable by Tenant to or on behalf of Landlord under this lease, whether or not
expressly denominated as rent, shall constitute rent for the purposes of the
Bankruptcy Code, 11 U.S.C. ss.502(b)(7).

         M. This is a contract under which applicable law excuses Landlord from
accepting performance from or rendering performance to any person or entity
other than Tenant within the meaning of the Bankruptcy Code, 11 U.S.C.
ss.365(c), 365(e)(2).

         N. If this Lease is assigned to any person or entity pursuant to the
provisions of the Bankruptcy Code, any and all monies or other considerations
payable or otherwise to be delivered in connection with such assignment shall be
paid or delivered to Landlord, shall be and remain the exclusive property of
Landlord and shall not constitute property of Tenant or of the estate of Tenant
within the meaning of the Bankruptcy Code. Any and all monies or other
considerations constituting Landlord's property under the preceding sentence not
paid or delivered to Landlord shall be held in trust for the benefit of Landlord
and be promptly paid or delivered to Landlord.

         O. Any person or entity to which this lease is assigned pursuant to the
provisions of the Bankruptcy Code, shall be deemed, without further act or deed,
to have assumed all of the


                                      -14-
<PAGE>   15

obligations arising under this Lease on and after the date of such assignment.
Any such assignee shall upon demand execute and deliver to Landlord an
instrument confirming such assumption.

         19. Omitted.

         20. Mortgages. Tenant accepts this lease subject and subordinate to any
mortgage(s) and/or deed(s) of trust now or at any time hereafter constituting a
lien or charge upon the premises or the improvements situated thereon, provided
however, that if the mortgagee, trustee, or holder of any such mortgage or deed
of trust elects to have Tenant's interest in this lease superior to any such
instrument, then by notice to Tenant from such mortgagee, trustee or holder,
this lease shall be deemed superior to such lien, whether this lease was
executed before or after said mortgage or deed of trust. Tenant shall at any
time hereafter on demand execute any instruments, releases or other documents
which may be required by any mortgagee for the purpose of subjecting and
subordinating this lease to the lien of any such mortgage.

         21. Landlord's Default. In the event Landlord should become in default
in any payments due on any such mortgage described in Paragraph 20 hereof or in
the payment of taxes or any other items which might become a lien upon the
premises and which Tenant is not obligated to pay under the terms and provisions
of this lease, Tenant is authorized and empowered after giving Landlord five (5)
days prior written notice of such default and Landlord's failure to cure such
default, to pay any such items for and on behalf of Landlord, and the amount of
any item so paid by Tenant for or on behalf of Landlord, together with any
interest or penalty required to be paid in connection therewith, shall be
payable on demand by Landlord to Tenant; provided however, that Tenant shall not
be authorized and empowered to make any payment under the terms of this
Paragraph 21 unless the item paid shall be superior to Tenant's interest
hereunder. In the event Tenant pays any mortgage debt in full, in accordance
with this paragraph, it shall, at its election, be entitled to the mortgage
security by assignment or subrogation.

         22. Mechanics Liens and Other Taxes.

         A.  Tenant shall have no authority, express or implied, to create or
place any lien or encumbrance of any kind or nature whatsoever upon, or in any
manner to bind the interests of Landlord in the premises or to charge the
rentals payable hereunder for any claim in favor of any person dealing with
Tenant, including those who may furnish materials or perform labor for any
construction or repairs, and each such claim shall affect and each such lien
shall attach to, if at all, only the leasehold interest granted to Tenant by
this instrument. Tenant covenants and agrees that it will pay or cause to be
paid all sums legally due and payable by it on account of any labor performed or
materials furnished in connection with any work performed on the premises on
which any lien is or can be validly and legally asserted against its leasehold
interest in the premises or the improvements thereon and that it will save and
hold Landlord harmless from any and all loss, cost or expense based on or
arising out of asserted claims or liens against the leasehold estate or against
the right, title and interest of the Landlord in the premises or under the terms
of this lease. Tenant agrees to give Landlord immediate written notice if any
lien or encumbrance is placed on the premises.


                                      -15-
<PAGE>   16


         B.  Tenant shall be liable for all taxes levied or assessed against
personal property, furniture or fixtures placed by Tenant in the premises. If
any such taxes for which Tenant is liable are levied or assessed against
Landlord or Landlord's property and if Landlord elects to pay the same or if the
assessed value of Landlord's property is increased by inclusion of personal
property, furniture or fixtures placed by Tenant in the premises, and Landlord
elects to pay the taxes based on such increase, Tenant shall pay to Landlord
upon demand that part of such taxes.

         23. Omitted.

         24. Certain Rights Reserved to Landlord. Landlord reserves and may
exercise the following rights without affecting Tenant's obligations hereunder:
(a) to change the name, street address, or suite numbers of the building; (b) to
install or maintain a sign or signs on the exterior of the building.

         25. Notices. Each provision of this instrument or of any applicable
governmental laws, ordinances, regulations and other requirements with reference
to the sending, mailing or delivery of any notice or the making of any payment
by Landlord to Tenant or with reference to the sending, mailing or delivery of
any notice or the making of any payment by Tenant to Landlord shall be deemed to
be complied with when and if the following steps are taken:

         A.  All rent and other payments required to be made by Tenant to
Landlord hereunder shall be payable to Landlord at the address hereinbelow set
forth or at such other address as Landlord may specify from time to time by

be deemed satisfied until such rent and other amounts have been actually
received by Landlord.

         B.  All payments required to be made by Landlord to Tenant hereunder
shall be payable to Tenant at the address hereinbelow set forth, or at such
other address within the continental United States as Tenant may specify from
time to time by written notice delivered in accordance herewith.

         C.  Any notice or document required or permitted to be delivered
hereunder shall be deemed to be delivered whether actually received or not when

subject to said conditions, Tenant agrees to indemnify and hold Landlord
harmless from all claims, demands, actions, liabilities, costs, expenses,
damages and obligations of any nature arising from or as a result


                                      -17-
<PAGE>   18


of the use of the premises by Tenant. The foregoing indemnification shall
survive the termination or expiration of this lease.

         27. Miscellaneous.

         A.  Words of any gender used in this lease shall be held and construed
to include any other gender, and words in the singular number shall be held to
include the plural, unless the context otherwise requires.

         B.  In the event the premises constitutes a portion of a multiple
occupancy building or building complex, Tenant's "proportionate share," as used
in this lease, shall mean a fraction, the numerator of which is the space
contained in the premises and the denominator of which is the entire space
contained in the building or building complex.

         C.  The terms, provisions and covenants and conditions contained in 
this lease shall apply to, inure to the benefit of, and be binding upon the
parties hereto and upon their respective heirs, legal representatives,
successors and permitted assigns, except as otherwise herein expressly provided.
Landlord shall have the right to assign any of its rights and obligations under
this lease. Each party agrees to furnish to the other, promptly upon demand, a
corporate resolution, proof of due authorization by partners, or other
appropriate documentation evidencing the due authorization of such party to
enter into this lease.

         D.  The captions inserted in this lease are for convenience only and in
no way define, limit or otherwise describe the scope or intent of this lease, or
any provision hereof, or in any way affect the interpretation of this lease.

         E.  Tenant agrees from time to time within ten (10) days after request
of Landlord, to deliver to Landlord, or Landlord's designee a certificate of
occupancy (if applicable) to an estoppel certificate stating that this lease is
in full force and effect, the date to which rent has been paid, the unexpired
term of this lease and such other matters pertaining to this lease as may be
requested by Landlord. It is understood and agreed that Tenant's obligation to
furnish such estoppel certificates in a timely fashion is a material inducement
for Landlord's execution of this lease.

         F.  This lease may not be altered, changed or amended except by an
instrument in writing signed by both parties hereto.

         G.  All obligations of Tenant hereunder not fully performed as of the
expiration or earlier termination of the term of this lease shall survive the
expiration or earlier termination of the term hereof, including without
limitation all payment obligations with respect to taxes and insurance and all
obligations concerning the condition of the premises. Upon the expiration or
earlier termination of the term hereof, and prior to Tenant vacating the
premises, Tenant shall pay to Landlord any amount reasonably as necessary to put
the premises, including without limitation all heating and air conditioning
systems and equipment therein, in good condition and repair. Tenant shall also,
prior to vacating the premises, pay to Landlord the amount of Tenant's
obligation hereunder for real estate


                                      -18-
<PAGE>   19


taxes and insurance premiums for the year in which the lease expires or
terminates. All such amounts shall be used and held by Landlord for payment of
such obligations of Tenant hereunder, with Tenant being liable for any
additional costs therefore upon demand by Landlord, or with any excess to be
returned to Tenant after all such obligations have been determined and
satisfied, as the case may be. Any security deposit held by Landlord shall be
credited against the amount payable by Tenant under this Subparagraph 27G.

         H.  If any clause or provision of this lease is illegal, invalid or
unenforceable under present or future laws effective during the term of this
lease, then and in that event, it is the intention of the parties hereto that
the remainder of this lease shall not be affected thereby, and it is also the
intention of the parties to this lease that in lieu of each clause or provision
of this lease that is illegal, invalid or unenforceable, there be added as a
part of this lease contract a clause or provision as similar in terms to such
illegal, invalid or unenforceable clause or provision as may be possible and be
legal, valid and enforceable.

         I.  Because the premises are on the open market and are presently being
shown, this lease shall be treated as an offer with the premises being subject
to prior lease and such offer subject to withdrawal or non-acceptance by
Landlord or to other use of the premises without notice, and this lease shall
not be valid or binding unless and until accepted by Landlord in writing and a
fully executed copy delivered to both parties hereto.

         J.  All references in this lease to "the date hereof" or similar
references shall be deemed to refer to the last date, in point of time, on which
all parties hereto have executed this lease.

         K.  Time is of the essence of this lease and all of its provisions.
This lease in all respect shall be governed by the laws of the State of Georgia.

         L.  No animals shall be brought into or kept in or about the building.

         M.  Tenant agrees to comply with subdivision regulations, protective
covenants, or other restrictions of record that are applicable to the building
or building complex.

         N.  The duties and obligations of Tenant herein shall be binding upon
all or any of them. The duties and obligations of Tenant shall run and extend
not only to the benefit of the Landlord, as named herein, but to the following,
at the option of the following or any of them (i) any person by, through or
under which Landlord derives the right to lease the premises; (ii) the owner of
the premises; and (ii) holders of mortgage or rent assignment interests in the
premises, as their respective interests may appear; provided, however, nothing
contained herein shall be construed to obligate Tenant to pay rent to any person
other than the Landlord until such time as Tenant has been given written notice
of either an exercise of a rent assignment or the succession of some other party
to the interests of Landlord.

                              ADDITIONAL PROVISIONS


         29. Tenant agrees to pay to Landlord rent for the premises, in advance,
without demand, deduction or set off, for the entire term hereof the following
base monthly rentals:

            (a) For each the first six (6) months of the term of this lease:
         $0.00 per month.

            (b) For each of months seven (7) through nineteen (19) of the term
         of this lease: $10,115.00 per month.

            (c) For each of months twenty (20) through forty-three (43) of the
         term of this lease: $11,799.00 per month.

            (d) For each of months forty-four (44) through fifty-five (55) of
         the term of this lease: $12,069.00 per month.

            (e) For each of months fifty-six (56) through sixty (60) of the term
         of this Lease: $13,483.00 per month.

         30. Tenant expressly agrees that the obligations incurred by Landlord
shall not constitute personal obligations of the officers, directors, trustees,
partners, joint venturers, members, stockholders, or other principals or
representatives of the Landlord. Tenant further agrees that it shall have
recourse against Landlord only to the extent of Landlord's assets for the
satisfaction of the obligations of the Landlord created under this Lease, and
not against the assets of such entity's officers, directors, trustees, partners,
joint venturers, members, stockholders, principals or representatives.

         31. Landlord covenants and agrees that if Tenant shall desert, vacate
or abandon the leased premises prior to the expiration or early termination of
the Lease Agreement, Landlord shall use reasonable efforts to lease the leased
premises to another Tenant.

         32. While this Lease is in full force and effect, provided Tenant is
not in default of the terms, covenants and conditions thereof, Tenant shall have
the sole right or option to extend the original term of this Lease Agreement for
a further consecutive term of twelve (12) months. Such extension or renewal of
the original term shall be on the same terms, covenants and conditions as
provided in the original term with the rent at the current rate at the time of
option. Notice of Tenant's intention to exercise this right or option must be
given in writing to Landlord on or before July 1, 1995, or the option contained
in this provision shall become null and void and of no effect. The right of
option to extend the original term of this Lease Agreement provided to Tenant
herein shall be for the exclusive benefit of the Tenant and shall terminate upon
the subletting of all or any part of the premises or assignment of this Lease.

ADDITIONAL PROVISIONS CONT.

         33. Notwithstanding any terms or provisions of this Lease which may be
construed to the contrary, Landlord and Tenant agree that Landlord will conduct
common area maintenance on the premises and grounds around the premises. Said
common area maintenance will include, but not be limited to, fire sprinkler
water charges, irrigation, lawn maintenance, security patrol and outside light
maintenance. The cost of said common area maintenance will be paid on a monthly
basis by Tenant and will amount to approximately SEVEN HUNDRED FIFTY-SIXTY AND
NO/100 DOLLARS ($756.00) per month. Landlord agrees that the monthly amount paid
by Tenant shall be capped at a compounded rate of ten percent (10%) per annum.
However, in the event Landlord elects to discontinue services or elects to
provide additional services as may be necessary under Paragraph 6 of this lease,
the monthly common area maintenance charge will be adjusted to reflect the
change in services provided.

         34. Landlord hereby covenants and agrees to use reasonable efforts to
cause any holder of a deed to secure debt or mortgage now or at any time
hereafter constituting a lien or charge upon the premises or the improvements
situated thereon to enter into a non-disturbance agreement pursuant to which
such holder shall agree that if it shall acquire the ownership of the premises
or the improvements situated thereon through the exercise of a power of sale or
other remedy provided for in such deed to secure debt or mortgage, it shall
permit Tenant to remain in possession of the premises in accordance with the
terms and provisions of this lease, provided that Tenant shall continue to
perform its duties and obligations hereunder.

         35. Landlord and Tenant shall each provide the other with certificates
evidencing the issuance of all policies of insurance required to be maintained
by them under the terms and provisions of this Lease. Such certificates shall be
so provided prior to the commencement date and, thereafter, not less than
fifteen (15) days prior to the expiration date of such policies.

         36. Notwithstanding any terms or the provisions of this Lease Agreement
which may be construed to the contrary, and provided this Lease Agreement is in
full force and effect and Tenant is not in default of the terms, covenants, and
conditions thereof, Tenant shall have the sole right or option to cancel this
Lease Agreement at the end of the thirty-sixth (36th) month of the lease term
by: (1) providing Landlord with at least one hundred twenty (120) days of prior
written notice of its desire to cancel this Lease Agreement, and (2)
simultaneously depositing with Landlord a cancellation fee to be determined by
multiplying $2,584.04 by 60 less the number of months of occupancy at the time
of cancellation. for example, the penalty at the end of the 36th month shall be
[60-36) x 2,5894.04] or $62,017.00. . Failure by Tenant to provide said written
notice and cancellation fee shall render this right or option null and void,
thus rendering this Lease Agreement in full force through the original sixty
(60) month lease term. The right of option to cancel this Lease Agreement shall
be for the exclusive benefit of the Tenant.

         37. Landlord agrees that Tenant and its contractors shall have the
right to possession of the premises at all times prior to the commencement date
for the purpose of constructing and 


                                      -2-

"Leasehold Improvements"). Prior the commencement date, Tenant shall perform all
of the obligation of this lease which are required to be performed by Tenant
during the term of this lease, except only for its obligations under Paragraphs
2, 4, and 29 of this lease.

         38. Notwithstanding the provisions of Paragraph 7 hereof, Tenant shall
have the option to remove the following improvements from the premises by the
date of termination of this Lease or upon earlier vacating of the premises
provided Tenant shall restore the premises to their original condition with
consideration for normal wear and tear. All such removals and restoration shall
be accomplished in a good workmanlike manner so as not to damage the primary
structure or structural qualities of the building and other improvements
situated on the premises:

                  (1)      Security Systems (e.g. access control units, CCTV
                           equipment, magnetic lock sets, internal intercoms,
                           electric lock sets, etc.)

                  (2)      Specialized packing equipment for manufacturing.

                                 LEASE AGREEMENT

         THIS LEASE AGREEMENT, made and entered into by and between PEACHTREE
CROSSINGS BUSINESS PARK ASSOCIATES hereinafter referred to as "Landlord" and
HAYES MICROCOMPUTER PRODUCTS, INC., a Georgia corporation, hereinafter referred
to as "Tenant."

                                W I T N E S E T H

         1. Premises and Term. In consideration of the obligation of Tenant to
pay rent as herein provided, and in consideration of the other terms, provisions
and covenants hereof, Landlord hereby demises and leases to Tenant, and Tenant
hereby accepts and leases from landlord certain premises situated within the
County of Gwinnett, State of Georgia, more particularly described on Exhibit "A"
attached hereto and incorporated herein by reference, together with all rights,
privileges, easements, appurtenances, and immunities belonging to or in any way
pertaining to the premises and together with the buildings and other
improvements situated or to be situated upon said premises (said real property,
building and improvements being hereinafter referred to as the "premises.")

         TO HAVE AND TO HOLD the same for a term commencing on the "commencement
date," as hereinafter defined, and ending on the last day of the month that is
sixty (60) months after the commencement date.

         A. The "commencement date" shall be January 1, 1991, and ending
December 31, 1995. Tenant acknowledges that it has inspected and accepts the
premises, and specifically the buildings and improvements comprising the same,
in their present condition, as suitable for the purpose for which the premises
are leased. Taking of possession by Tenant shall be deemed conclusively to
establish that said buildings and other improvements are in good and
satisfactory condition as of when possession was taken. Tenant further
acknowledges that no representations as to the repair of the premises, nor
promises to alter, remodel or improve the premises have been made by Landlord,
unless such are expressly set forth in this lease. If this lease is executed
before the premises become vacant or otherwise available and ready for
occupancy, or if any present tenant or occupant of the premises holds over, the
Landlord cannot acquire possession of the premises prior to said "commencement
date." Landlord shall not be deemed to be in default hereunder, and Tenant
agrees to accept possession of the premises at such time as Landlord is able to
tender the same, which date shall thenceforth be deemed the "commencement date,"
and Landlord hereby waives payment of rent covering any period prior to the
tendering of possession to Tenant hereunder. After the commencement date the
Tenant shall, upon demand, execute and deliver to Landlord a letter of
acceptance of delivery of the premises.

         2. Base Rent and Security Deposit. See Additional Provision #29.

         A. Omitted.

         B. In addition, Tenant has deposited with Landlord the sum of
TWENTY-SIX THOUSAND EIGHT HUNDRED SEVENTY-FIVE AND NO/100 DOLLARS ($26,875.00),
which sum shall be held by Landlord, without obligation for interest, as
security for the performance of Tenant's covenants and obligations under this
lease, it being expressly understood and agreed that such deposit is not an
advance rental deposit or a measure of Landlord's damages in case of Tenant's
default. Upon the occurrence of any event of default by Tenant, Landlord may,
from time to time, without prejudice to any other remedy provided herein or
provided by law, use such fund to the extent necessary to make good any arrears
of rent or other payments due Landlord hereunder, and any other damage, injury,
expense or liability caused by such event of default, and Tenant shall pay to
Landlord on demand the amount so applied in order to restore the security
deposit to its original amount. Although the security deposit shall be deemed
the property of Landlord, any remaining balance of such deposit shall be
returned by Landlord to Tenant at such time after termination of this lease that
all of Tenant's obligations under this lease have been fulfilled.

         3. Use. The demised premises shall be used only for the purpose of
general office, receiving, storing, manufacturing, repairing, shipping and
selling (other than retail) products, materials and merchandise made and/or
distributed by Tenant and for such other lawful purposes as may be incidental
thereto, and subject to any building or building complex rules and regulations
which shall not impair Tenant's use of the premises. Outside storage, including
without limitation, trucks and other vehicles, is prohibited without Landlord's
prior written consent. Tenant shall at its own cost and expense obtain any and
all licenses and permits necessary for any such use. Tenant shall comply with
all governmental laws, ordinances and regulations applicable to the use of the
premises, and shall promptly comply with all governmental orders and directives
for the correction, prevention and abatement of nuisances in or upon, or
connected with the premises, all at Tenant's sole expense. Tenant shall not
permit any objectionable or unpleasant odors, smoke, dust, gas, noise or
vibrations to emanate from the premises, nor take any other action which would
constitute a nuisance or would disturb or endanger any other tenants of the
building in which their premises are situated or unreasonably interfere with
their use of their respective premises. Without Landlord's prior written
consent, Tenant shall not receive, store or otherwise handle any product,
material or merchandise which is explosive or highly flammable. Tenant will not
permit the premises to be used for any purpose or in any manner, including,
without limitation, any method of storage which would render the insurance
thereon void or the insurance risk more hazardous or cause the State Board of
insurance or other insurance authority to disallow any sprinkler credits. If any
increase in the fire and extended coverage insurance premiums paid by Landlord
or other tenants for the building in which Tenant occupies space is caused by
Tenant's use and occupancy of the premises, or if Tenant vacates the premises
and causes an increase in such premiums, then Tenant shall pay as additional
rental the amount of such increase to Landlord.


                                      -2-

         Tenant agrees that the point pressure resulting from Tenant's racking
system, inventory, forklifts and equipment pertaining to Tenant's use of the
premises shall not exceed allowable design floor loading for floor slabs on
grade. Tenant shall hold harmless Landlord from any loss, liability, and
expenses, both real and alleged, arising out of such damage or repair caused by
Tenant's negligence or failure to comply with this paragraph.

         4. Taxes.

         A. Landlord agrees to pay before they become delinquent all taxes,
assessments and governmental charges of any kind and nature whatsoever
thereinafter collectively referred to as "taxes" lawfully levied or assessed
against the building and the grounds, parking areas, driveways and alleys around
the building; provided, however, that the maximum amount of taxes to be paid by
Landlord hereunder during any one real estate tax year shall be ZERO AND NO/100
DOLLARS ($0.00). If in any real estate tax year during the term hereof or any
renewal or extension the taxes levied or assessed against the building and the
grounds, parking areas, driveways and alleys around the building during such tax
year shall exceed the sum set forth in the preceding sentence, Tenant shall pay
to Landlord as additional rental, upon demand, the amount of such excess. In the
event any such amount is not paid within twenty (20) days after the date of
Landlord's invoice to Tenant, the unpaid amount shall bear interest at the rate
of twenty (20%) percent per annum from the date of such invoice until payment by
Tenant. In the event the premises constitute a portion of a multiple occupancy
building, Tenant agrees to pay to Landlord as additional rental, upon demand,
the amount of Tenant's "proportionate share" (as defined in subparagraph 27B) of
the excess taxes referred to in this subparagraph above.

         B. If at any time during the term of this lease, the present method of
taxation shall be changed so that in lieu of the whole or any part of any taxes,
assessments, or governmental charges levied, assessed or imposed on real estate
and the improvements thereon, there shall be levied, assessed or imposed on
Landlord a capital levy or other tax directly on the rents received therefrom
and/or a franchise tax, assessment, levy or charge measured by or based, in
whole or in part, upon such rents for the present or any future building or
buildings on the premises, then all such taxes, assessments, levies or charges,
or the part thereof so measured or based shall be deemed to be included within
the term "taxes" for the purposes hereof.

         C. The Landlord shall have the right to engage a tax consulting firm to
attempt to assure a fair tax burden for the building and grounds within the
applicable taxing jurisdiction. Tenant shall pay to Landlord upon demand, from
time to time, as additional rent, the amount of Tenant's proportionate share of
the cost of such service.

         D. Any payment to be made pursuant to this Paragraph 4 with respect to
the real estate tax year in which this lease commences or terminates shall be
prorated.

         5. Landlord's Repairs and Obligations. Landlord shall at his expense
maintain only the roof, foundation and the structural soundness of the exterior
walls of the building in good repair, reasonable wear and tear excepted. Tenant
shall repair and pay for any damage caused by the


                                      -3-
<PAGE>   4

negligence of Tenant, or Tenant's employees, agents or invitees, or caused by
Tenant's default hereunder. The term "walls' as used herein shall not include
windows, glass or plate glass, doors, store fronts or office entries. Tenant
shall immediately give Landlord written notice of defect or need for repairs,
after which Landlord shall have reasonable opportunity to repair same or cure
such defect. Landlord's liability with respect to any defects, repairs or
maintenance for which Landlord is responsible under any of the provisions of
this lease shall be limited to the cost of such repairs or maintenance or the
curing of such defect.

         6. Tenant's Repairs and Obligations.

         A. Tenant shall at its own cost and expense keep and maintain all parts
of the premises (except those for which Landlord is expressly responsible under
the terms of this lease) in good condition, promptly making all necessary
repairs, repainting, and replacements, including but not limited to, windows,
glass and plate glass, doors, any office entries, interior walls and finish
work, floors and floor covering, downspouts, gutters, heating and air
conditioning systems, dock boards, truck doors, dock bumpers, paving, plumbing
work and fixtures, termites and pest extermination, regular removal of trash and
debris, grounds maintenance, common sewage line plumbing, common exterior
lighting (if applicable), common dumpster removal (if applicable) and other
obligations of the building, including, but not limited to, keeping the parking
areas, driveways, alleys and the whole of the premises in a clean and sanitary
condition. Tenant shall not be obligated to repair any damage caused by fire,
tornado or other casualty covered by the insurance to be maintained by Landlord
pursuant to subparagraph 12A below, except that Tenant shall be obligated to
repair all wind damage to glass except with respect to tornado or hurricane
damage.

         B. The cost of maintenance and repair of any common party walls (any
wall, divider, partition or any other structure separating the premises from any
adjacent premises) shall be shared equally by Tenant and the tenant or tenants
occupying adjacent premises. Tenant shall not damage any demising wall or
disturb the integrity and support provided by any demising wall and shall, at
its sole cost and expense, promptly repair any damage or injury to any demising
wall caused by Tenant or its employees, agents or invitees.

         C. In the event the premises constitute a portion of a multiple
occupancy building, Tenant and its employees, customers and licensees shall have
the exclusive right to use the parking areas, if any, as may be designated by
Landlord in writing, subject to such reasonable rules and regulations as
Landlord may from time to time prescribe and subject to rights of ingress and
egress of other tenants. Landlord shall not be responsible for enforcing
Tenant's exclusive parking rights against any third parties. Parking spaces have
been provided in accordance with applicable local building codes and anticipated
needs of tenants. Tenant agrees not to use more than its proportionate share as
so provided.

         D. Landlord reserves the right to perform and provide all of Tenant's
repairs and obligations under subparagraph 6A above, and Tenant shall, in lieu
of the obligations set forth under subparagraph 6A above with respect to such
items, pay monthly as additional rent due under Paragraph 2A for its
proportionate share of the cost and expense, including overhead, for those



                                      -4-
<PAGE>   5

items; provided, however, that Landlord shall have the right to require Tenant
to pay such other reasonable proportions of said repairs and obligations as may
be determined by Landlord in its sole discretion; and further provided that if
Tenant or any other particular tenant of the building can be clearly identified
as being responsible for obstructions or stoppage of the common sanitary sewage
line, then Tenant, if Tenant is responsible, shall pay the entire cost thereof,
upon demand, as additional rent.

         E. Omitted.

         F. Tenant shall, at its own cost and expense, enter into a regularly
scheduled preventive maintenance/service contract with a maintenance contractor
and the contract must be approved by Landlord. The service contract must include
all services suggested by the equipment manufacturer within the
operation/maintenance manual and must become effective (and a copy thereof
delivered to Landlord) within thirty (30) days of the date Tenant takes
possession of the premises.

         7. Alterations. Tenant shall not make any alterations, additions or
improvements to the premises (including, but not limited to, roof and wall
penetrations) without the prior written consent of Landlord. Such consent will
not be denied provided the improvements are building standard office/warehouse
finishes. In the event Landlord consents to the making of any such alterations,
additions or improvements by Tenant, the same shall be made by Tenant, at
Tenant's sole cost and expense, in accordance with all applicable laws,
ordinances and regulations, and all requirements of Landlord's and Tenant's
insurance policies and only in accordance with plans and specifications approved
by Landlord; and any contractor or person selected by Tenant to make the same
and all subcontractors must first be approved in writing by Landlord. Tenant
may, without the consent of Landlord, but at its own cost and expense and in a
good workmanlike manner erect such shelves, bins, machinery and trade fixtures
as it may deem advisable, without altering the basic character of the building
or improvements and without overloading or damaging such building or
improvements, and in each case complying with all applicable governmental laws,
ordinances, regulations and other requirements. All alterations, additions,
improvements and partitions erected by Tenant shall be and remain the property
of Tenant during the term of this lease and Tenant shall, unless Landlord
otherwise elects as hereinafter provided, remove all alterations, additions,
improvements and partitions erected by Tenant and restore the premises to their
original condition by the date of termination of this lease or upon earlier
vacating of the premises; provided, however, that if Landlord so elects prior to
termination of this lease or upon earlier vacating of the premises, such
alterations, additions, improvements and partitions shall become the property of
Landlord as of the date of termination of this lease or upon earlier vacating of
the premises and shall be delivered up to the Landlord with the premises. All
shelves, bins, machinery and trade fixtures installed by Tenant may be removed
by Tenant prior to the termination of this lease if Tenant so elects, and shall
be removed by the date of termination of this lease or upon earlier vacating of
the premises if required by Landlord; upon any such removal Tenant shall restore
the premises to their original condition with consideration for normal wear and
tear. All such removals and restoration shall be accomplished in a good
workmanlike manner so as not to damage the primary structure or structural
qualities of the building and other improvements situated on the premises.



                                      -5-
<PAGE>   6

         8.  Signs. Tenant agrees to conform to Landlord's signage program for
the building; however, all costs and expense of the sign, sign installation,
removal and repair shall be paid by Tenant. Tenant shall only have the right to
install standard signs upon the premises where first approved in writing by
Landlord and subject to any applicable governmental laws, ordinances,
regulations and other requirements. Tenant shall remove all signs prior to the
termination of this lease. Such installations and removals shall be made in such
a manner as to avoid injury or defacement of the building and other
improvements, and Tenant shall repair any injury or defacement, including,
without limitation, discoloration caused by installation and/or removal.

         9.  Inspection and Right of Entry. Landlord and Landlord's agents and
representatives shall have the right to enter the premises at any time in the
event of an emergency and to enter and inspect the premises at any reasonable
time during business hours, for the purpose of ascertaining the condition of the
premises in order to make such repairs as may be required or permitted to be
made by Landlord under the terms of this lease. During the period that is six
(6) months prior to the end of the term hereof, Landlord and Landlord's agents
and representatives shall have the right to enter the premises at any reasonable
time during business hours for the purpose of showing the premises and shall
have the right to erect on the premises a suitable sign indicating the premises
are available. Tenant shall arrange to meet with Landlord for a joint inspection
of the premises prior to vacating. In the event of Tenant's failure to arrange
such joint inspection, Landlord's inspection at or after Tenant's vacating the
premises shall be conclusively deemed correct for purposes of determining
Tenant's responsibility for repairs and restoration.

         10. Utilities. Landlord agrees to provide at its cost water,
electricity and gas (when applicable) service connections into the premises; but
Tenant shall pay for all water, gas, heat, light, power, telephone, sewer,
sprinkler charges and other utilities and services used on or from the premises,
together with any taxes, penalties, surcharges or the like pertaining thereto
and any maintenance charges for utilities and shall furnish all electric light
bulbs and tubes. If any such services are not separately metered to Tenant,
Tenant shall pay a reasonable proportion as determined by Landlord of all
charges jointly metered with other premises, provided, however, Landlord shall
have the right to require Tenant to pay such other reasonable proportion of said
jointly metered charges as may be determined by Landlord in its sole discretion.
Landlord shall in no event by liable for any interruption or failure of utility
services on the premises.

         11. Assignment and Subletting.

         A.  Tenant shall not have the right to assign, sublet, transfer or
encumber this lease, or any interest therein, without the prior written consent
of Landlord. Any attempted assignment, subletting, transfer or encumbrance by
Tenant in violation of the terms and covenants of this Paragraph shall be void.
All cash or other proceeds of any assignment, such proceeds as exceed the
rentals called for hereunder in the case of a subletting and all cash or other
proceeds of any other transfer of Tenant's interest in this lease shall be paid
to Landlord, whether such assignment, subletting or other transfer is consented
to by Landlord or not, unless Landlord agrees to the contrary in writing, and
Tenant hereby assigns all rights it might have or ever acquire in any such
proceeds to Landlord. Any assignment, subletting or other transfer of Tenant's
interest in this lease shall be


                                      -6-
<PAGE>   7


for an amount equal to the then fair market value of such interest. These
covenants shall run with the land and shall bind Tenant and Tenant's heirs,
executors, administrators, personal representatives, representatives in any
bankruptcy proceeding, successors and assigns. any assignee, sublessee or
transferee of Tenant's interest in this lease (all such assignees, sublessees
and transferees being hereinafter referred to as "successors"), by assuming
Tenant's obligations hereunder shall assume liability to Landlord for all
amounts paid to persons other than Landlord by such successors in contravention
of this Paragraph. No assignments, subletting or other transfer, whether
consented to by Landlord or not, shall relieve Tenant of its liability
hereunder. Upon the occurrence of an "event of default" as hereinafter defined,
if the premises or any part thereof are then assigned or sublet, Landlord, in
addition to any other remedies herein provided, or provided by law, may at its
option collect directly from such assignee or subtenant all rents becoming due
to Tenant under such assignment or sublease and apply such rent against any sums
due to Landlord from Tenant hereunder, and no such collection shall be construed
to constitute a novation or a release of Tenant from the further performance of
Tenant's obligations hereunder.

         B.  If this lease is assigned to any person or entity pursuant to the
provisions of the Bankruptcy Code 11 U.S.C. ss. 101, et seq. (the "Bankruptcy
Code"), any and all monies or other considerations payable or otherwise to be
delivered in connection with such assignment shall be paid or delivered to
Landlord, shall be and remain the exclusive property of Landlord and shall not
constitute property of Tenant or of the estate of Tenant within the meaning of
the Bankruptcy Code. Any and all monies or other considerations constituting
Landlord's property under the preceding sentence not paid or delivered to
Landlord shall be held in trust for the benefit of the Landlord and promptly
paid or delivered to Landlord.

         C.  Any person or entity to which this lease is assigned pursuant to 
the provisions of the Bankruptcy Code, shall be deemed, without further act or
deed, to have assumed all of the obligations arising under this lease on and
after the date of such assignment. Any such assignee shall upon demand execute
and deliver to Landlord an instrument confirming such assumption.

         12. Fire and Casualty Damage.

         A.  Landlord agrees to maintain insurance covering the building of 
which the premises are a part (including building standard office/warehouse
finishes which are constructed by Tenant) in an amount not less than eighty
(80%) percent (or such greater percentage as may be necessary to comply with the
provisions of any co-insurance clauses of the policy) of the replacement cost
thereof, insuring against the perils of Fire, Lightning, Extended Coverage,
Vandalism and Malicious Mischief, extended by Special Extended Coverage
Endorsement to insure against all other regulatory authority for the state in
which the premises are situated for use by insurance companies admitted in such
state for the writing of such insurance on risks located within such state.
Subject to the provisions of subparagraphs 12C, 12D and 12E below, such
insurance shall be for the sole benefit of Landlord and under its sole control.
If, during the second calendar year after the commencement date of this lease,
or during any subsequent calendar year of the primary term or any renewal or
extension, Landlord's cost of maintaining such insurance shall exceed Landlord's
cost of maintaining such insurance for the first calendar year or the term
hereof, Tenant agrees to pay to Landlord, as


                                      -7-
<PAGE>   8

additional rental, the amount of such excess not to exceed $4,128.00 per year
(or in the event the premises constitute a portion of a multiple occupancy
building, Tenant's full proportionate share of such excess). The first calendar
year shall be the year in which the lease commences. Said payments shall be made
to Landlord within ten (10) days after presentation to Tenant of Landlord's
statement setting forth the amount due. Any payment to be made pursuant to this
subparagraph A with respect to the year in which this lease commences or
terminates shall bear the same ratio to the payment which would be required to
be made for the full year as the part of such year covered by the term of this
lease bears to a full year.

         B. If the buildings situated upon the premises should be damaged or
destroyed by fire, tornado or other casualty, Tenant shall give immediate
written notice thereof to Landlord.

         C. If the buildings situated upon the premises should be totally
destroyed by fire, tornado or other casualty, or if they should be so damaged
thereby that rebuilding or repairs cannot in Landlord's reasonable estimation be
completed within one hundred twenty (120) days after the date upon which
Landlord is notified by Tenant of such damage, this lease shall terminate and
the rent shall be abated during the unexpired portion of this lease, effective
upon the date of the occurrence of such damage.

         D. If the buildings situated upon the premises should be damaged by any
peril covered by the insurance to be provided by Landlord under subparagraph 12A
above, but only to such extent that rebuilding or repairs can in Landlord's
reasonable estimation be completed within one hundred twenty (120) days after
the date upon which Landlord is notified by Tenant of such damage, this lease
shall not terminate, and Landlord shall at its sole cost and expense thereupon
proceed with reasonable diligence to rebuild and repair such buildings to
substantially the condition in which they existed prior to such damage, except
that Landlord shall not be required to rebuild, repair or replace any part of
the partitions, fixtures, additions and other improvements which may have been
placed in, on or about the premises by Tenant and except that Landlord may elect
not to rebuild if such damage occurs during the last year of the term of the
lease exclusive of any option which is unexercised at the time of such damage.
If the premises are untenantable in whole or in part following such damage, the
rent payable hereunder during the period in which they are untenantable shall be
reduced to such extent as may be fair and reasonable under all of the
circumstances. In the event that Landlord should fail to complete such repairs
and rebuilding within one hundred twenty (120) days after the date upon which
Landlord is notified by Tenant of such damage, Tenant may at its option
terminate this lease by delivering written notice of termination to Landlord as
Tenant's exclusive remedy, whereupon all rights and obligations hereunder shall
cease and terminate.

         E. Notwithstanding anything herein to the contrary, in the event the
holder of any indebtedness secured by a mortgage or deed of trust covering the
premises requires that the insurance proceeds be applied to such indebtedness,
then Landlord shall have the right to terminate this lease by delivering written
notice of termination to Tenant within fifteen (15) days after such requirement
is made by any such holder, whereupon all rights and obligations hereunder shall
cease and terminate.


                                      -8-
<PAGE>   9

         F.  Each of Landlord and Tenant hereby releases the other from any loss
or damage to property caused by fire or any other perils insured in policies of
insurance covering such property, even if such loss or damage shall have been
caused by the fault or negligence of the other party, or anyone for whom such
other party may be responsible. Each of the Landlord and Tenant agrees that it
will request its insurance carriers to include in its policies such a clause or
endorsement. If extra cost shall be charged therefore, each party shall advise
the other thereof and of the amount of the extra cost, and the other party, at
its election, may pay the same, but it shall not be obligated to do so.

         13. Liability. Landlord shall not be liable to Tenant or Tenant's
employees, agents, patrons or visitors, or to any other person whomsoever, for
any injury to person or damage to property on or about the premises, resulting
from and or caused in part or whole by the negligence or misconduct of Tenant,
its agents, servants or employee of any other person entering upon the premises,
or caused by the buildings and improvements located on the premises becoming out
of repair, or caused by leakage of gas, oil, water or steam or by electricity
emanating from the premises, or due to any cause whatsoever, and Tenant hereby
covenants and agrees that it will at all times indemnify and hold safe and
harmless the property, the Landlord (including without limitation the trustee
and beneficiaries if Landlord is a trust), landlord's agents and employees from
any loss, liability, claims, suits, costs, expenses, including without
limitation attorney's fees and damages, both real and alleged, arising out of
any such damage or injury, except injury to persons or damage to property the
cause of which is the negligence of Landlord or the failure of Landlord to
repair any part of the premises which Landlord is obligated to repair and
maintain hereunder within a reasonable time after the receipt of written notice
from Tenant of needed repairs. Tenant shall procure and maintain throughout the
term of this lease a policy or policies of insurance, at its sole cost and
expense, insuring both Landlord and Tenant against all claims, demands or
actions arising out of or in connection with: (i) the premises; (ii) the
condition of the premises; (iii) Tenant's operations in and maintenance and use
of the premises; and (iv) Tenant's liability assumed under this lease, the
limits of such policy or policies to be in the amount of not less than
$1,000,000.00 per occurrence in respect to injury to persons (including death),
and in the amount of not less than $100,000 per occurrence in respect to
property damage or destruction, including loss of use thereof. All such policies
shall be procured by Tenant from responsible insurance companies satisfactory to
Landlord. Certificates evidencing such policies, together with receipt
evidencing payment of premiums therefor, shall be delivered to Landlord prior to
the commencement date of this lease. Not less than fifteen (15) days prior to
the expiration date of any such policies, certificates evidencing the renewals
thereof (bearing notations evidencing the payment of renewal premiums) shall be
delivered to Landlord. Such policies shall further provide that not less than
thirty (30) days written notice shall be given to Landlord before such policy
may be cancelled or changed to reduce insurance provided thereby.

         14. Condemnation.

         A.  If the whole or any substantial part of the premises should be
taken for any public or quasi-public use under governmental law, ordinance or
regulation, or by right of eminent domain, or by private purchase in lieu
thereof and the taking would prevent or materially interfere with the


                                      -9-
<PAGE>   10


use of the premises for the purposes for which they are being used, this lease
shall terminate and the rent shall be abated during the unexpired portion of
this lease, effective when the physical taking of said premises shall occur.

         B.  If part of the premises shall be taken for any public or
quasi-public use under any governmental law, ordinance or regulation, or by
right of eminent domain, or by private purchase in lieu thereof, and this lease
is not terminated as provided in the subparagraph above, this lease shall not
terminate but the rent payable hereunder during the unexpired portion of this
lease shall be reduced to such extent as may be fair and reasonable under all of
the circumstances.

         C.  All compensation awarded for any taking (or the proceeds of private
sale in lieu thereof) of the premises, buildings or other improvements, or any
part thereof, shall be the property of Landlord and Tenant hereby assigns its
interest in any such award to Landlord; provided, however, Landlord shall have
no interest in any award made to Tenant for loss of business or for the taking
of Tenant's fixtures and improvements if a separate award for such items is made
to Tenant.

         15. Holding Over. Tenant will, at the termination of this lease by
lapse of time or otherwise, yield up immediate possession to Landlord with all
repairs and maintenance required herein to be performed by Tenant completed. If
Landlord agrees in writing that Tenant may hold over after the expiration or
termination of this lease, unless the parties hereto otherwise agree in writing
on the terms of such holding over, the hold over tenancy shall be subject to
termination by Landlord at any time upon not less than five (5) days advance
written notice, or by Tenant at any time upon not less than thirty (30) days
advance written notice, and all of the other terms and provisions of this lease
shall be applicable during that period, except that Tenant shall pay Landlord
from time to time upon demand, as rental for the period of any hold over, an
amount equal to double the rent in effect on the termination date, computed on a
daily basis for each day of the hold over period. No holding over by Tenant,
whether with or without consent of Landlord, shall operate to extend this lease
except as otherwise expressly provided. The preceding provisions of this
paragraph 15 shall not be construed as consent for Tenant to hold over.

         16. Quiet Enjoyment. Landlord covenants that it now has good title to
the premises, free and clear of all liens and encumbrances, excepting only the
lien for current taxes not yet due, such mortgage or mortgages as are permitted
by the terms of this lease, zoning ordinances and other building and fire
ordinances and governmental regulations relating to the use of such property,
and easements, restrictions and other conditions of record. Landlord represents
and warrants that it has full right and authority to enter into this lease and
that Tenant, upon paying the rental herein set forth and performing its other
covenants and agreements herein set forth, shall peaceably and quietly have,
hold and enjoy the premises for the term hereof without hindrance or molestation
from Landlord, subject to the terms and provisions of this lease.

         17. Events of Default. The following events shall be deemed to be
events of default by Tenant under this lease:


                                      -10-
<PAGE>   11


         A.  Tenant shall fail to pay any installment of the rent herein 
reserved when due, or any other payment or reimbursement to Landlord required
herein when due, and such failure shall continue for a period of ten (10) days
from the date such payment was due.

         B.  Tenant or any guarantor of Tenant's obligations hereunder shall
generally not pay its debts as they become due or shall admit in writing its
inability to pay its debts or shall make a general assignment for the benefit of
creditors, or Tenant or any such guarantor shall commence any case, proceeding
or other action seeking to have an order for relief entered on its behalf as a
debtor or to adjudicate it as bankrupt or insolvent, or seeking reorganization,
arrangement, adjustment, liquidation, dissolution, or composition of it or its
debts under any law relating to bankruptcy, insolvency, reorganization or relief
of debtors or seeking appointment of a receiver, trustee, custodian or other
similar official for it or for all or of any substantial part of its property,

contemplation of any of the actions set forth above in this paragraph, or

         C.  Any case, proceeding or other action against Tenant or any 
guarantor of Tenant's obligations hereunder shall be commenced seeking to have

or insolvent, or seeking reorganization, arrangement, adjustment, liquidation,
dissolution or composition of it or its debts under any law relating to
bankruptcy, insolvency, reorganization or relief of debtors, or seeking
appointment of a receiver, trustee, custodian or other similar official for it
or for all or any substantial part of its property.

<PAGE>   12



            (1)         Terminate this lease, in which event Tenant shall
                        immediately surrender the premises to Landlord, and if
                        Tenant fails so to do, Landlord may, without prejudice
                        to any other remedy which it may have for possession or
                        arrearage in rent, enter upon and take possession of the
                        premises and expel or remove Tenant and any other person
                        who may be occupying such premises or any part thereof,
                        by force if necessary, without being liable for
                        prosecution or any claim of damage therefore.

            (2)         Enter upon and take possession of the premises and expel
                        or remove Tenant and any other person who may be
                        occupying such premises or any part thereof, by force if
                        necessary, without being liable for prosecution or any
                        claim for damages therefore.

            (3)         Enter upon the Premises, by force if necessary, without
                        being liable for prosecution or any claim for damages
                        therefore, and do whatever Tenant is obligated to do
                        under the terms of this lease; and Tenant agrees to
                        reimburse Landlord on demand for any expenses which
                        Landlord may incur in thus effecting the compliance with
                        Tenant's obligations under this Lease, and Tenant
                        further agrees that Landlord shall not be liable for any
                        damages resulting to the Tenant from such action,
                        whether caused by the negligence of Landlord or
                        otherwise.

            (4)         Alter all locks and other security devices at the
                        premises without terminating this lease.

         B. In the event Landlord may elect to regain possession of the premises
by a forcible detainer proceeding, Tenant hereby specifically waives any
statutory notice which may be required prior to such proceeding, and agrees that
Landlord's execution of this lease is, in part, consideration of this waiver.

         C. In the event Tenant fails to pay any installment of rent hereunder
as and when such installment is due, to help defray the additional cost to
Landlord for processing such late payments Tenant shall pay to Landlord on
demand a late charge in an amount equal to five (5%) percent of such
installment; and the failure to pay such amount within five (5) days after
demand therefore shall be an event of default hereunder. The provision for such
late charge shall be in addition to all of Landlord's other rights and remedies
hereunder or at law and shall not be construed as liquidated damages or as
limiting Landlord's remedies in any manner.

         D. In the event Tenant's check, given to Landlord in payment, is
returned by the bank for non-payment, Tenant agrees to pay all expenses incurred
by Landlord as a result thereof.

         E. Exercise by Landlord of any one or more remedies hereunder granted
or otherwise available shall not be deemed to be an acceptance or surrender of
the premises by Tenant, whether by agreement or by operation of law, it being
understood that such surrender can be effected only


                                      -12-
<PAGE>   13

by the written agreement of Landlord and Tenant. No such alteration of locks or
other security devices and no removal or other exercise of dominion by Landlord
over the property of Tenant or others at the premises shall be deemed
unauthorized or constitute a conversion, Tenant hereby consenting, after any
event of default, to the aforesaid exercise of dominion over Tenant's property
within the premises. All claims for damages by reason of such re-entry and/or
repossession and/or alteration of locks or other security devices are hereby
waived, as are all claims for damages by reason of any distress warrant,
forcible detainer proceedings, sequestration proceedings or other legal process.
Tenant agrees that any re-entry by Landlord may be pursuant to judgment obtained
in forcible detainer proceedings or other legal proceedings or without the
necessity for any legal proceedings, as Landlord may elect, and Landlord shall
not be liable for trespass or otherwise.

         F. Omitted.

         G. In the event that Landlord elects to repossess the premises without
terminating the lease, or in the event Landlord elects to terminate the lease,
then Tenant, at Landlord's option, shall be liable for and shall pay to
Landlord, at the address specified for notice to Landlord herein, all rental and
other indebtedness accrued to the date of such repossession, plus rental
required to be paid by Tenant to Landlord during the remainder of the lease term
until the date of expiration of the term as stated in Paragraph 1 diminished by
any net sums thereafter received by Landlord through reletting the premises
during said period (after deducting expenses incurred by Landlord as provided in
subparagraph 18H below). In no event shall Tenant be entitled to any excess of
any rental obtained by reletting over and above the rental herein reserved.
Actions to collect amounts due by Tenant to Landlord under this subparagraph may
be brought from time to time, on one or more occasions, without the necessity of
Landlord's waiting until expiration of the lease term.

         H. In case of any event of default or breach by Tenant, or threatened
or anticipatory breach or default, Tenant shall also be liable for and shall pay
to Landlord, at the address specified for notice to Landlord herein, in addition
to any sum provided to be paid above, brokers' fees incurred by Landlord in
connection with reletting the whole or any part of the premises; the costs of
removing and storing Tenant's or other occupant's property; the costs of
repairing, altering, remodeling or otherwise putting the premises into condition
acceptable to a new tenant or tenants, and all reasonable expenses incurred by
Landlord in enforcing or defending Landlord's rights and/or remedies including
reasonable attorney's fees.

         I. In the event of termination or repossession of the premises for an
event of default, Landlord shall not have any obligation to relet or to attempt
to relet the premises, or any portion thereof; and in the event of reletting,
Landlord may relet the whole or any portion of the premises for any period to
any tenant and for any use and purpose.

         J. If Tenant should fail to make any payment or cure any default
hereunder within the time herein permitted, Landlord, without being under any
obligation to do so and without thereby waiving such default, may make such
payment and/or remedy such other default for the account of Tenant (and enter
the premises for such purpose), and thereupon Tenant shall be obligated to, and



                                      -13-
<PAGE>   14

hereby agrees, to pay Landlord upon demand, all costs, expenses and
disbursements (including reasonable attorney's fees) incurred by Landlord in
taking such remedial action.

         K. In the event that Landlord shall have taken possession of the
premises pursuant to the authority herein granted then Landlord shall have the
right to keep in place and use all of the furniture, fixtures and equipment at
the premises, including that which is owned by or leased to Tenant at all times
prior to any foreclosure thereon by Landlord or repossession thereof by any
lessor thereof or third party having a lien thereon. Landlord shall also have
the right to remove from the premises (without the necessity of obtaining a
distress warrant, writ of sequestration or other legal process) all or any
portion of such furniture, fixtures, equipment and other property located
thereon and to place same in storage at any premises within the County in which
the premises is located; and in such event, Tenant shall be liable to Landlord
for costs incurred by Landlord in connection with such removal and storage.
Landlord shall also have the right to relinquish possession of all or any
portion of such furniture, fixtures, equipment and other property to any person
("Claimant") claiming to be entitled to possession thereof who presents to
Landlord a copy of any instrument represented to Landlord by Claimant to have
been executed by Tenant (or any predecessor Tenant) granting Claimant the right
under various circumstances to take possession of such furniture, fixtures,
equipment or other property, without the necessity on the part of Landlord to
inquire into the authenticity of said instrument's copy of Tenant's or Tenant's
predecessor's signature(s) thereon and without the necessity of Landlord making
any nature of investigation or inquiry as to the validity of the factual or
legal basis upon which Claimant purports to act; and Tenant agrees to indemnity
and hold Landlord harmless from all cost, expense, loss, damage and liability
incident to Landlord's relinquishment of possession of all or any portion of
such furniture, fixtures, equipment or other property to Claimant. The rights of
Landlord herein stated shall be in addition to any and all other rights which
Landlord has or may hereafter have at law or in equity; and Tenant stipulates
and agrees that the rights herein granted Landlord are commercially reasonable.

         L. Notwithstanding anything in this lease to the contrary, all amounts
payable by Tenant to or on behalf of Landlord under this lease, whether or not
expressly denominated as rent, shall constitute rent for the purposes of the
Bankruptcy Code, 11 U.S.C. ss.502(b)(7).

         M. This is a contract under which applicable law excuses Landlord from
accepting performance from or rendering performance to any person or entity
other than Tenant within the meaning of the Bankruptcy Code, 11 U.S.C.
ss.365(c), 365(e)(2).

         N. If this Lease is assigned to any person or entity pursuant to the
provisions of the Bankruptcy Code, any and all monies or other considerations
payable or otherwise to be delivered in connection with such assignment shall be
paid or delivered to Landlord, shall be and remain the exclusive property of
Landlord and shall not constitute property of Tenant or of the estate of Tenant
within the meaning of the Bankruptcy Code. Any and all monies or other
considerations constituting Landlord's property under the preceding sentence not
paid or delivered to Landlord shall be held in trust for the benefit of Landlord
and be promptly paid or delivered to Landlord.


                                      -14-
<PAGE>   15

         O.  Any person or entity to which this lease is assigned pursuant to 
the provisions of the Bankruptcy Code, shall be deemed, without further act or
deed, to have assumed all of the obligations arising under this Lease on and
after the date of such assignment. Any such assignee shall upon demand execute
and deliver to Landlord an instrument confirming such assumption.

         19. Omitted.

         20. Mortgages. Tenant accepts this lease subject and subordinate to any
mortgage(s) and/or deed(s) of trust now or at any time hereafter constituting a
lien or charge upon the premises or the improvements situated thereon, provided
however, that if the mortgagee, trustee, or holder of any such mortgage or deed
of trust elects to have Tenant's interest in this lease superior to any such
instrument, then by notice to Tenant from such mortgagee, trustee or holder,
this lease shall be deemed superior to such lien, whether this lease was
executed before or after said mortgage or deed of trust. Tenant shall at any
time hereafter on demand execute any instruments, releases or other documents
which may be required by any mortgagee for the purpose of subjecting and
subordinating this lease to the lien of any such mortgage.

         21. Landlord's Default. In the event Landlord should become in default
in any payments due on any such mortgage described in Paragraph 20 hereof or in
the payment of taxes or any other items which might become a lien upon the
premises and which Tenant is not obligated to pay under the terms and provisions
of this lease, Tenant is authorized and empowered after giving Landlord five (5)
days prior written notice of such default and Landlord's failure to cure such
default, to pay any such items for and on behalf of Landlord, and the amount of
any item so paid by Tenant for or on behalf of Landlord, together with any
interest or penalty required to be paid in connection therewith, shall be
payable on demand by Landlord to Tenant; provided however, that Tenant shall not
be authorized and empowered to make any payment under the terms of this
Paragraph 21 unless the item paid shall be superior to Tenant's interest
hereunder. In the event Tenant pays any mortgage debt in full, in accordance
with this paragraph, it shall, at its election, be entitled to the mortgage
security by assignment or subrogation.

         22. Mechanics Liens and Other Taxes.

         A.  Tenant shall have no authority, express or implied, to create or
place any lien or encumbrance of any kind or nature whatsoever upon, or in any
manner to bind the interests of Landlord in the premises or to charge the
rentals payable hereunder for any claim in favor of any person dealing with
Tenant, including those who may furnish materials or perform labor for any
construction or repairs, and each such claim shall affect and each such lien
shall attach to, if at all, only the leasehold interest granted to Tenant by
this instrument. Tenant covenants and agrees that it will pay or cause to be
paid all sums legally due and payable by it on account of any labor performed or
materials furnished in connection with any work performed on the premises on
which any lien is or can be validly and legally asserted against its leasehold
interest in the premises or the improvements thereon and that it will save and
hold Landlord harmless from any and all loss, cost or expense based on or
arising out of asserted claims or liens against the leasehold estate or against
the right, title and interest of the Landlord in the premises or under the terms
of this lease. Tenant


                                      -15-
<PAGE>   16


agrees to give Landlord immediate written notice if any lien or encumbrance is
placed on the premises.

         B.  Tenant shall be liable for all taxes levied or assessed against
personal property, furniture or fixtures placed by Tenant in the premises. If
any such taxes for which Tenant is liable are levied or assessed against
Landlord or Landlord's property and if Landlord elects to pay the same or if the
assessed value of Landlord's property is increased by inclusion of personal
property, furniture or fixtures placed by Tenant in the premises, and Landlord
elects to pay the taxes based on such increase, Tenant shall pay to Landlord
upon demand that part of such taxes.

         23. Omitted.

         24. Certain Rights Reserved to Landlord. Landlord reserves and may
exercise the following rights without affecting Tenant's obligations hereunder:
(a) to change the name, street address, or suite numbers of the building; (b) to
install or maintain a sign or signs on the exterior of the building.

         25. Notices. Each provision of this instrument or of any applicable
governmental laws, ordinances, regulations and other requirements with reference
to the sending, mailing or delivery of any notice or the making of any payment
by Landlord to Tenant or with reference to the sending, mailing or delivery of
any notice or the making of any payment by Tenant to Landlord shall be deemed to
be complied with when and if the following steps are taken:

         A.  All rent and other payments required to be made by Tenant to
Landlord hereunder shall be payable to Landlord at the address hereinbelow set
forth or at such other address as Landlord may specify from time to time by
written notice delivered in accordance herewith. Tenant's obligations to pay
rent and any other amounts to Landlord under the terms of this lease shall not
be deemed satisfied until such rent and other amounts have been actually
received by Landlord.

         B.  All payments required to be made by Landlord to Tenant hereunder
shall be payable to Tenant at the address hereinbelow set forth, or at such
other address within the continental United States as Tenant may specify from
time to time by written notice delivered in accordance herewith.

         C.  Any notice or document required or permitted to be delivered
hereunder shall be deemed to be delivered whether actually received or not when

       LANDLORD:                                TENANT:

         26. Hazardous Waste. The term "Hazardous Substances," as used in this
lease shall mean pollutants, contaminants, toxic or hazardous wastes, or any
other substances, the removal of which is required or the use of which is
restricted, prohibited or penalized by any "Environmental Law," which term shall
mean any federal, state or local law or ordinance relating to pollution or
protection of the environment. Tenant hereby agrees that (i) no activity will be
conducted on the premises that will produce any Hazardous Substance, except for
such activities that are part of the ordinary course of Tenant's business
activities that are part of the ordinary course of Tenant's business (the
"Permitted Activities") provided said Permitted Activities are conducted in
accordance with all Environmental Laws and have been approved in advance in
writing by Landlord; (ii) the premises will not be used in any manner for the
storage of any Hazardous Substances except for the temporary storage of such

or after the term of the lease, the premises is found to be so contaminated or
subject to said conditions, Tenant agrees to indemnify and hold Landlord
harmless from all claims, demands, actions, liabilities, costs, expenses,
damages and obligations of any nature arising from or as a result


                                      -17-
<PAGE>   18

of the use of the premises by Tenant. The foregoing indemnification shall
survive the termination or expiration of this lease.

         27. Miscellaneous.

         A.  Words of any gender used in this lease shall be held and construed
to include any other gender, and words in the singular number shall be held to
include the plural, unless the context otherwise requires.

         B.  In the event the premises constitutes a portion of a multiple
occupancy building or building complex, Tenant's "proportionate share," as used
in this lease, shall mean a fraction, the numerator of which is the space
contained in the premises and the denominator of which is the entire space
contained in the building or building complex.

         C.  The terms, provisions and covenants and conditions contained in 
this lease shall apply to, inure to the benefit of, and be binding upon the
parties hereto and upon their respective heirs, legal representatives,
successors and permitted assigns, except as otherwise herein expressly provided.
Landlord shall have the right to assign any of its rights and obligations under
this lease. Each party agrees to furnish to the other, promptly upon demand, a
corporate resolution, proof of due authorization by partners, or other
appropriate documentation evidencing the due authorization of such party to
enter into this lease.

         D.  The captions inserted in this lease are for convenience only and in
no way define, limit or otherwise describe the scope or intent of this lease, or
any provision hereof, or in any way affect the interpretation of this lease.

         E.  Tenant agrees from time to time within ten (10) days after request
of Landlord, to deliver to Landlord, or Landlord's designee a certificate of
occupancy (if applicable) to an estoppel certificate stating that this lease is
in full force and effect, the date to which rent has been paid, the unexpired
term of this lease and such other matters pertaining to this lease as may be
requested by Landlord. It is understood and agreed that Tenant's obligation to
furnish such estoppel certificates in a timely fashion is a material inducement
for Landlord's execution of this lease.

         F.  This lease may not be altered, changed or amended except by an
instrument in writing signed by both parties hereto.

         G.  All obligations of Tenant hereunder not fully performed as of the
expiration or earlier termination of the term of this lease shall survive the
expiration or earlier termination of the term hereof, including without
limitation all payment obligations with respect to taxes and insurance and all
obligations concerning the condition of the premises. Upon the expiration or
earlier termination of the term hereof, and prior to Tenant vacating the
premises, Tenant shall pay to Landlord any amount reasonably as necessary to put
the premises, including without limitation all heating and air conditioning
systems and equipment therein, in good condition and repair. Tenant shall also,
prior to vacating the premises, pay to Landlord the amount of Tenant's
obligation hereunder for real estate


                                      -18-
<PAGE>   19

taxes and insurance premiums for the year in which the lease expires or
terminates. All such amounts shall be used and held by Landlord for payment of
such obligations of Tenant hereunder, with Tenant being liable for any
additional costs therefore upon demand by Landlord, or with any excess to be
returned to Tenant after all such obligations have been determined and
satisfied, as the case may be. Any security deposit held by Landlord shall be
credited against the amount payable by Tenant under this Subparagraph 27G.

         H. If any clause or provision of this lease is illegal, invalid or
unenforceable under present or future laws effective during the term of this
lease, then and in that event, it is the intention of the parties hereto that
the remainder of this lease shall not be affected thereby, and it is also the
intention of the parties to this lease that in lieu of each clause or provision
of this lease that is illegal, invalid or unenforceable, there be added as a
part of this lease contract a clause or provision as similar in terms to such
illegal, invalid or unenforceable clause or provision as may be possible and be
legal, valid and enforceable.

         I. Because the premises are on the open market and are presently being
shown, this lease shall be treated as an offer with the premises being subject
to prior lease and such offer subject to withdrawal or non-acceptance by
Landlord or to other use of the premises without notice, and this lease shall
not be valid or binding unless and until accepted by Landlord in writing and a
fully executed copy delivered to both parties hereto.

         J. All references in this lease to "the date hereof" or similar
references shall be deemed to refer to the last date, in point of time, on which
all parties hereto have executed this lease.

         K. Time is of the essence of this lease and all of its provisions. This
lease in all respect shall be governed by the laws of the State of Georgia.

         L. No animals shall be brought into or kept in or about the building.

         M. Tenant agrees to comply with subdivision regulations, protective
covenants, or other restrictions of record that are applicable to the building
or building complex.

         N. The duties and obligations of Tenant herein shall be binding upon
all or any of them. The duties and obligations of Tenant shall run and extend
not only to the benefit of the Landlord, as named herein, but to the following,
at the option of the following or any of them (i) any person by, through or
under which Landlord derives the right to lease the premises; (ii) the owner of
the premises; and (ii) holders of mortgage or rent assignment interests in the
premises, as their respective interests may appear; provided, however, nothing
contained herein shall be construed to obligate Tenant to pay rent to any person
other than the Landlord until such time as Tenant has been given written notice
of either an exercise of a rent assignment or the succession of some other party
to the interests of Landlord.

                              ADDITIONAL PROVISIONS


       29. Tenant agrees to pay to Landlord rent for the premises, in advance,
without demand, deduction or set off, for the entire term hereof the following
base monthly rentals:

            (a) For each of months one (1) through twelve (12) of the term of
this lease: $12,900.00 per month.

            (b) For each of months thirteen (13) through thirty-six (36) of the
term of this lease: $26,875.00 per month.

            (c) For each of moths thirty-seven (37) through forty-eight (48) of
the term of this lease: $29,025.00 per month.

            (d) For each of months forty-nine (49) through sixty (60) of the
term of this lease: $30,100.00 per month.

       30. Tenant expressly agrees that the obligations incurred by Landlord
shall not constitute personal obligations of the officers, directors, trustees,
partners, joint venturers, members, stockholders, or other principals or
representatives of the Landlord. Tenant further agrees that it shall have
recourse against Landlord only to the extent of Landlord's assets for the
satisfaction of the obligations of the Landlord created under this Lease, and
not against the assets of such entity's officers, directors, trustees, partners,
joint venturers, members, stockholders, principals or representatives.

       31. Landlord covenants and agrees that if Tenant shall desert, vacate or
abandon the leased premises prior to the expiration or early termination of the
Lease Agreement, Landlord shall use reasonable efforts to lease the leased
premises to another Tenant.

       32. While this Lease is in full force and effect, provided Tenant is not
in default of the terms, covenants and conditions thereof, Tenant shall have the
sole right or option to extend the original term of this Lease Agreement for a
further consecutive term of twelve (12) months. Such extension or renewal of the
original term shall be on the same terms, covenants and conditions as provided
in the original term with the rent at the current rate at the time of option.
Notice of Tenant's intention to exercise this right or option must be given in
writing to Landlord on or before July 1, 1995, or the option contained in this
provision shall become null and void and of no effect. The right of option to
extend the original term of this Lease Agreement provided to Tenant herein shall
be for the exclusive benefit of the Tenant and shall terminate upon the
subletting of all or any part of the premises or assignment of this Lease.

       33. Notwithstanding any terms or provisions of this Lease which may be
construed to the contrary, Landlord and Tenant agree that Landlord will conduct
common area maintenance on the premises and grounds around the premises. Said
common area maintenance will include, but not

<PAGE>   22

ADDITIONAL PROVISIONS CONT.

be limited to, fire sprinkler water charges, irrigation, lawn maintenance,
security patrol and outside light maintenance. The cost of said common area
maintenance will be paid on a monthly basis by Tenant and will amount to
approximately SEVEN HUNDRED NINE AND NO/100 DOLLARS ($709.00) per month.
Landlord agrees that the monthly amount paid by Tenant shall be capped at a
compounded rate of ten percent (10%) per annum. However, in the event Landlord
elects to discontinue services or elects to provide additional services as may
be necessary under Paragraph 6 of this lease, the monthly common area
maintenance charge will be adjusted to reflect the change in services provided.

       34. Landlord hereby covenants and agrees to use reasonable efforts to
cause any holder of a deed to secure debt or mortgage now or at any time
hereafter constituting a lien or charge upon the premises or the improvements
situated thereon to enter into a non-disturbance agreement pursuant to which
such holder shall agree that if it shall acquire the ownership of the premises
or the improvements situated thereon through the exercise of a power of sale or
other remedy provided for in such deed to secure debt or mortgage, it shall
permit Tenant to remain in possession of the premises in accordance with the
terms and provisions of this lease, provided that Tenant shall continue to
perform its duties and obligations hereunder.

       35. Landlord and Tenant shall each provide the other with certificates
evidencing the issuance of all policies of insurance required to be maintained
by them under the terms and provisions of this Lease. Such certificates shall be
so provided prior to the commencement date and, thereafter, not less than
fifteen (15) days prior to the expiration date of such policies.

       36. Notwithstanding any terms or the provisions of this Lease Agreement
which may be construed to the contrary, and provided this Lease Agreement is in
full force and effect and Tenant is not in default of the terms, covenants, and
conditions thereof, Tenant shall have the sole right or option to cancel this
Lease Agreement at the end of the thirty-sixth (36th) month of the lease term
by: (1) providing Landlord with at least one hundred twenty (120) days of prior
written notice of its desire to cancel this Lease Agreement, and (2)
simultaneously depositing with Landlord a cancellation fee to be determined by
the following formula: [(5.85 x 51,600 x N/12)-(Total base rent paid by Tenant
through the cancellation month as provided in the rent schedule in Paragraph
29)]. N is equal to the number of months of Tenant's occupancy through the
cancellation month. For example, the penalty due at the end of the 36th month
shall be [(5.85 x 51,600 x 36/12)-(799,800)] or $105,780.00. Failure by Tenant
to provide said written notice and cancellation fee shall render this right or
option null and void, thus rendering this Lease Agreement in full force through
the original sixty (60) month lease term. The right of option to cancel this
Lease Agreement shall be for the exclusive benefit of the Tenant.

       37. Notwithstanding the provisions of Paragraph 7 hereof, Tenant shall
have the option to remove the following improvements from the premises by the
date of termination of this Lease or upon earlier vacating of the premises
provided Tenant shall restore the premises to their original

condition with consideration for normal wear and tear. All such removals and
restoration shall be accomplished in a good workmanlike manner so as not to
damage the primary structure or structural qualities of the building and other
improvements situated on the premises:

             (1)  Security Systems (e.g. access control units, CCTV equipment,
                  magnetic lock sets, internal intercoms, electric lock sets,
                  etc.)

             (2)  Support equipment for specializing manufacturing.

             (3)  Life Safety/Fire Control Panel.

             (4)  Telephone switching units.

             (5)  Air compressor units to support operations.

             (6)  Specialized air conditioning units (localized small self 
                  contained units - not roof units).

                                 LEASE AGREEMENT

         THIS LEASE AGREEMENT, made and entered into by and between PEACHTREE
CROSSINGS BUSINESS PARK ASSOCIATES hereinafter referred to as "Landlord" and
HAYES MICROCOMPUTER PRODUCTS, INC., a Georgia corporation, hereinafter referred
to as "Tenant."

                                W I T N E S E T H


         1. Premises and Term. In consideration of the obligation of Tenant to
pay rent as herein provided, and in consideration of the other terms, provisions
and covenants hereof, Landlord hereby demises and leases to Tenant, and Tenant
hereby accepts and leases from landlord certain premises situated within the
County of Gwinnett, State of Georgia, more particularly described on Exhibit "A"
attached hereto and incorporated herein by reference, together with all rights,
privileges, easements, appurtenances, and immunities belonging to or in any way
pertaining to the premises and together with the buildings and other
improvements situated or to be situated upon said premises (said real property,
building and improvements being hereinafter referred to as the "premises.")

         TO HAVE AND TO HOLD the same for a term commencing on the "commencement
date," as hereinafter defined, and ending on the last day of the month that is
sixty (60) months after the commencement date.

         A. The "commencement date" shall be September 1, 1993, and ending
August 31, 1998. Tenant acknowledges that it has inspected and accepts the
premises, and specifically the buildings and improvements comprising the same,
in their present condition, as suitable for the purpose for which the premises
are leased. Taking of possession by Tenant shall be deemed conclusively to
establish that said buildings and other improvements are in good and
satisfactory condition as of when possession was taken. Tenant further
acknowledges that no representations as to the repair of the premises, nor
promises to alter, remodel or improve the premises have been made by Landlord,
unless such are expressly set forth in this lease. If this lease is executed
before the premises become vacant or otherwise available and ready for
occupancy, or if any present tenant or occupant of the premises holds over, the
Landlord cannot acquire possession of the premises prior to said "commencement
date." Landlord shall not be deemed to be in default hereunder, and Tenant
agrees to accept possession of the premises at such time as Landlord is able to
tender the same, which date shall thenceforth be deemed the "commencement date,"
and Landlord hereby waives payment of rent covering any period prior to the
tendering of possession to Tenant hereunder. After the commencement date the
Tenant shall, upon demand, execute and deliver to Landlord a letter of
acceptance of delivery of the premises.


<PAGE>   2


         2. Base Rent and Security Deposit.

         A. Tenant agrees to pay to Landlord rent for the premises, in advance,
without demand, deduction or set off, for the entire term hereof at the rate of
ELEVEN THOUSAND SIX HUNDRED FORTY FIVE AND NO/100 DOLLARS ($11,645.00) per
month. One such monthly installment shall be due and payable on the date hereof
and a like monthly installment shall be due and payable on or before the first
day of each calendar month succeeding the commencement date recited above during
the hereby demised term, except that the rental payment for any fractional
calendar month at the commencement or end of the lease period shall be prorated.
The rental payment is subject to adjustment as provided below.

         B. In addition, Tenant agrees to deposit with Landlord on the date
hereof the sum of ZERO AND NO/100 DOLLARS ($0.00), which sum shall be held by
Landlord, without obligation for interest, as security for the performance of
Tenant's covenants and obligations under this lease, it being expressly
understood and agreed that such deposit is not an advance rental deposit or a
measure of Landlord's damages in case of Tenant's default. Upon the occurrence
of any event of default by Tenant, Landlord may, from time to time, without
prejudice to any other remedy provided herein or provided by law, use such fund
to the extent necessary to make good any arrears of rent or other payments due
Landlord hereunder, and any other damage, injury, expense or liability caused by
such event of default, and Tenant shall pay to Landlord on demand the amount so
applied in order to restore the security deposit to its original amount.
Although the security deposit shall be deemed the property of Landlord, any
remaining balance of such deposit shall be returned by Landlord to Tenant at
such time after termination of this lease that all of Tenant's obligations under
this lease have been fulfilled.

         3. Use. The demised premises shall be used only for the purpose of
general office, receiving, storing, manufacturing, repairing, shipping and
selling (other than retail) products, materials and merchandise made and or
distributed by Tenant and for such other lawful purposes as may be incidental
thereto, and subject to any building or building complex rules and regulations
which shall not impair Tenant's use of the premises. Outside storage, including
without limitation, trucks and other vehicles, is prohibited without Landlord's
prior written consent. Tenant shall at its own cost and expense obtain any and
all licenses and permits necessary for any such use. Tenant shall comply with
all governmental laws, ordinances and regulations applicable to the use of the
premises, and shall promptly comply with all governmental orders and directives
for the correction, prevention and abatement of nuisances in or upon, or
connected with the premises, all at Tenant's sole expense. Tenant shall not
permit any objectionable or unpleasant odors, smoke, dust, gas, noise or
vibrations to emanate from the premises, nor take any other action which would
constitute a nuisance or would disturb or endanger any other tenants of the
building in which their premises are situated or unreasonably interfere with
their use of their respective premises. Without Landlord's prior written
consent, Tenant shall not receive, store or otherwise handle any product,
material or merchandise which is explosive or highly flammable. Tenant will not
permit the premises to be used for any purpose or in any manner, including,
without limitation, any method of storage which would render the insurance
thereon void or the insurance risk more hazardous or cause the State Board of
insurance or other insurance authority to disallow any sprinkler credits. If any
increase in


                                      -2-
<PAGE>   3



the fire and extended coverage insurance premiums paid by Landlord or other
tenants for the building in which Tenant occupies space is caused by Tenant's
use and occupancy of the premises, or if Tenant vacates the premises and causes
an increase in such premiums, then Tenant shall pay as additional rental the
amount of such increase to Landlord.

         Tenant agrees that the point pressure resulting from Tenant's racking
system, inventory, forklifts and equipment pertaining to Tenant's use of the
premises shall not exceed allowable design floor loading for floor slabs on
grade. Tenant shall hold harmless Landlord from any loss, liability, and
expenses, both real and alleged, arising out of such damage or repair caused by
Tenant's negligence or failure to comply with this paragraph.

         4. Taxes.

         A. Landlord agrees to pay before they become delinquent all taxes,
assessments and governmental charges of any kind and nature whatsoever
thereinafter collectively referred to as "taxes" lawfully levied or assessed
against the building and the grounds, parking areas, driveways and alleys around
the building; provided, however, that the maximum amount of taxes to be paid by
Landlord hereunder during any one real estate tax year shall be ZERO AND NO/100
DOLLARS ($0.00). If in any real estate tax year during the term hereof or any
renewal or extension the taxes levied or assessed against the building and the
grounds, parking areas, driveways and alleys around the building during such tax
year shall exceed the sum set forth in the preceding sentence, Tenant shall pay
to Landlord as additional rental, upon demand, the amount of such excess. In the
event any such amount is not paid within twenty (20) days after the date of
Landlord's invoice to Tenant, the unpaid amount shall bear interest at the rate
of twenty percent (20%) per annum from the date of such invoice until payment by
Tenant. In the event the premises constitute a portion of a multiple occupancy
building, Tenant agrees to pay to Landlord as additional rental, upon demand,
the amount of Tenant's "proportionate share" (as defined in subparagraph 27B) of
the excess taxes referred to in this subparagraph above.

         B. If at any time during the term of this lease, the present method of
taxation shall be changed so that in lieu of the whole or any part of any taxes,
assessments, or governmental charges levied, assessed or imposed on real estate
and the improvements thereon, there shall be levied, assessed or imposed on
Landlord a capital levy or other tax directly on the rents received therefrom
and/or a franchise tax, assessment, levy or charge measured by or based, in
whole or in part, upon such rents for the present or any future building or
buildings on the premises, then all such taxes, assessments, levies or charges,
or the part thereof so measured or based shall be deemed to be included within
the term "taxes" for the purposes hereof.

         C. The Landlord shall have the right to engage a tax consulting firm to
attempt to assure a fair tax burden for the building and grounds within the
applicable taxing jurisdiction. Tenant shall pay to Landlord upon demand, from
time to time, as additional rent, the amount of Tenant's proportionate share of
the cost of such service.

                                      - 3 -


<PAGE>   4



         D. Any payment to be made pursuant to this Paragraph 4 with respect to
the real estate tax year in which this lease commences or terminates shall be
prorated.

         5. Landlord's Repairs and Obligations. Landlord shall at his expense
maintain only the roof, foundation and the structural soundness of the exterior
walls of the building in good repair, reasonable wear and tear excepted. Tenant
shall repair and pay for any damage caused by the negligence of Tenant, or
Tenant's employees, agents or invitees, or caused by Tenant's default hereunder.
The term "walls' as used herein shall not include windows, glass or plate glass,
doors, store fronts or office entries. Tenant shall immediately give Landlord
written notice of defect or need for repairs, after which Landlord shall have
reasonable opportunity to repair same or cure such defect. Landlord's liability
with respect to any defects, repairs or maintenance for which Landlord is
responsible under any of the provisions of this lease shall be limited to the
cost of such repairs or maintenance or the curing of such defect.

         6. Tenant's Repairs and Obligations.

         A. Tenant shall at its own cost and expense keep and maintain all parts
of the premises (except those for which Landlord is expressly responsible under
the terms of this lease) in good condition, promptly making all necessary
repairs, repainting, and replacements, including but not limited to, windows,
glass and plate glass, doors, any office entries, interior walls and finish
work, floors and floor covering, downspouts, gutters, heating and air
conditioning systems, dock boards, truck doors, dock bumpers, paving, plumbing
work and fixtures, termites and pest extermination, regular removal of trash and
debris, grounds maintenance, common sewage line plumbing, common exterior
lighting (if applicable), common dumpster removal (if applicable)and other
obligations of the building, including, but not limited to, keeping the parking
areas, driveways, alleys and the whole of the premises in a clean and sanitary
condition. Tenant shall not be obligated to repair any damage caused by fire,
tornado or other casualty covered by the insurance to be maintained by Landlord
pursuant to subparagraph 12A below, except that Tenant shall be obligated to
repair all wind damage to glass except with respect to tornado or hurricane
damage.

         B. The cost of maintenance and repair of any common party walls (any
wall, divider, partition or any other structure separating the premises from any
adjacent premises) shall be shared equally by Tenant and the tenant or tenants
occupying adjacent premises. Tenant shall not damage any demising wall or
disturb the integrity and support provided by any demising wall and shall, at
its sole cost and expense, promptly repair any damage or injury to any demising
wall caused by Tenant or its employees, agents or invitees.

         C. In the event the premises constitute a portion of a multiple
occupancy building, Tenant and its employees, customers and licensees shall have
the exclusive right to use the parking areas, if any, as may be designated by
Landlord in writing, subject to such reasonable rules and regulations as
Landlord may from time to time prescribe and subject to rights of ingress and
egress of other tenants. Landlord shall not be responsible for enforcing
Tenant's exclusive parking rights against any third parties. Parking spaces have
been provided in accordance with applicable local


                                      -4-
<PAGE>   5

building codes and anticipated needs of tenants. Tenant agrees not to use more
than its proportionate share as so provided.

         D. Landlord reserves the right to perform and provide all of Tenant's
repairs and obligations under subparagraph 6A above, and Tenant shall, in lieu
of the obligations set forth under subparagraph 6A above with respect to such
items, pay monthly as additional rent due under Paragraph 2A for its
proportionate share of the cost and expense, including overhead, for those
items; provided, however, that Landlord shall have the right to require Tenant
to pay such other reasonable proportions of said repairs and obligations as may
be determined by Landlord in its sole discretion; and further provided that if
Tenant or any other particular tenant of the building can be clearly identified
as being responsible for obstructions or stoppage of the common sanitary sewage
line, then Tenant, if Tenant is responsible, shall pay the entire cost thereof,
upon demand, as additional rent.

         E. Omitted.

         F. Tenant shall, at its own cost and expense, enter into a regularly
scheduled preventive maintenance/service contract with a maintenance contractor
and the contract must be approved by Landlord. The service contract must include
all services suggested by the equipment manufacturer within the
operation/maintenance manual and must become effective (and a copy thereof
delivered to Landlord) within thirty (30) days of the date Tenant takes
possession of the premises.

         7. Alterations. Tenant shall not make any alterations, additions or
improvements to the premises (including, but not limited to, roof and wall
penetrations) without the prior written consent of Landlord. Such consent will
not be denied provided the improvements are building standard office/warehouse
finishes. In the event Landlord consents to the making of any such alterations,
additions or improvements by Tenant, the same shall be made by Tenant, at
Tenant's sole cost and expense, in accordance with all applicable laws,
ordinances and regulations, and all requirements of Landlord's and Tenant's
insurance policies and only in accordance with plans and specifications approved
by Landlord; and any contractor or person selected by Tenant to make the same
and all subcontractors must first be approved in writing by Landlord. Tenant
may, without the consent of Landlord, but at its own cost and expense and in a
good workmanlike manner erect such shelves, bins, machinery and trade fixtures
as it may deem advisable, without altering the basic character of the building
or improvements and without overloading or damaging such building or
improvements, and in each case complying with all applicable governmental laws,
ordinances, regulations and other requirements. All alterations, additions,
improvements and partitions erected by Tenant shall be and remain the property
of Tenant during the term of this lease and Tenant shall, unless Landlord
otherwise elects as hereinafter provided, remove all alterations, additions,
improvements and partitions erected by Tenant and restore the premises to their
original condition by the date of termination of this lease or upon earlier
vacating of the premises; provided, however, that if Landlord so elects prior to
termination of this lease or upon earlier vacating of the premises, such
alterations, additions, improvements and partitions shall become the property of
Landlord as of the date of termination of this lease or upon earlier vacating of
the premises, and shall be delivered up to the Landlord with the premises. All
shelves, bins, machinery and trade fixtures installed by


                                      -5-

Tenant may be removed by Tenant prior to the termination of this lease if Tenant
so elects, and shall be removed by the date of termination of this lease or upon
earlier vacating of the premises if required by Landlord; upon any such removal
Tenant shall restore the premises to their original condition with consideration
for normal wear and tear. All such removals and restoration shall be
accomplished in a good workmanlike manner so as not to damage the primary
structure or structural qualities of the building and other improvements
situated on the premises.

         8.  Signs. Tenant agrees to conform to Landlord's signage program for
the building; however, all costs and expense of the sign, sign installation,
removal and repair shall be paid by Tenant. Tenant shall only have the right to
install standard signs upon the premises where first approved in writing by
Landlord and subject to any applicable governmental laws, ordinances,
regulations and other requirements. Tenant shall remove all signs prior to the
termination of this lease. Such installations and removals shall be made in such
a manner as to avoid injury or defacement of the building and other
improvements, and Tenant shall repair any injury or defacement, including,
without limitation, discoloration caused by installation and/or removal.

         9.  Inspection and Right of Entry. Landlord and Landlord's agents and
representatives shall have the right to enter the premises at any time in the
event of an emergency and to enter and inspect the premises at any reasonable
time during business hours, for the purpose of ascertaining the condition of the
premises in order to make such repairs as may be required or permitted to be
made by Landlord under the terms of this lease. During the period that is six
(6) months prior to the end of the term hereof, Landlord and Landlord's agents
and representatives shall have the right to enter the premises at any reasonable
time during business hours for the purpose of showing the premises and shall
have the right to erect on the premises a suitable sign indicating the premises
are available. Tenant shall arrange to meet with Landlord for a joint inspection
of the premises prior to vacating. In the event of Tenant's failure to arrange
such joint inspection, Landlord's inspection at or after Tenant's vacating the
premises shall be conclusively deemed correct for purposes of determining
Tenant's responsibility for repairs and restoration.

         10. Utilities. Landlord agrees to provide at its cost water,
electricity and gas (when applicable) service connections into the premises; but
Tenant shall pay for all water, gas, heat, light, power, telephone, sewer,
sprinkler charges and other utilities and services used on or from the premises,
together with any taxes, penalties, surcharges or the like pertaining thereto
and any maintenance charges for utilities and shall furnish all electric light
bulbs and tubes. If any such services are not separately metered to Tenant,
Tenant shall pay a reasonable proportion as determined by Landlord of all
charges jointly metered with other premises, provided, however, Landlord shall
have the right to require Tenant to pay such other reasonable proportion of said
jointly metered charges as may be determined by Landlord in its sole discretion.
Landlord shall in no event by liable for any interruption or failure of utility
services on the premises.

         11. Assignment and Subletting.

         A.  Tenant shall not have the right to assign, sublet, transfer or
encumber this lease, or any interest therein, without the prior written consent
of Landlord. Any attempted assignment,

                                      -6-
<PAGE>   7



subletting, transfer or encumbrance by Tenant in violation of the terms and
covenants of this Paragraph shall be void. All cash or other proceeds of any
assignment, such proceeds as exceed the rentals called for hereunder in the case
of a subletting and all cash or other proceeds of any other transfer of Tenant's
interest in this lease shall be paid to Landlord, whether such assignment,
subletting or other transfer is consented to by Landlord or not, unless Landlord
agrees to the contrary in writing, and Tenant hereby assigns all rights it might
have or ever acquire in any such proceeds to Landlord. Any assignment,
subletting or other transfer of Tenant's interest in this lease shall be for an
amount equal to the then fair market value of such interest. These covenants
shall run with the land and shall bind Tenant and Tenant's heirs, executors,
administrators, personal representatives, representatives in any bankruptcy
proceeding, successors and assigns. any assignee, sublessee or transferee of
Tenant's interest in this lease (all such assignees, sublessees and transferees
being hereinafter referred to as "successors"), by assuming Tenant's obligations
hereunder shall assume liability to Landlord for all amounts paid to persons
other than Landlord by such successors in contravention of this Paragraph. No
assignments, subletting or other transfer, whether consented to by Landlord or
not, shall relieve Tenant of its liability hereunder. Upon the occurrence of an
"event of default" as hereinafter defined, if the premises or any part thereof
are then assigned or sublet, Landlord, in addition to any other remedies herein
provided, or provided by law, may at its option collect directly from such
assignee or subtenant all rents becoming due to Tenant under such assignment or
sublease and apply such rent against any sums due to Landlord from Tenant
hereunder, and no such collection shall be construed to constitute a novation or
a release of Tenant from the further performance of Tenant's obligations
hereunder.

         B.  If this lease is assigned to any person or entity pursuant to the
provisions of the Bankruptcy Code 11 U.S.C. ss. 101, et seq. (the "Bankruptcy
Code"), any and all monies or other considerations payable or otherwise to be
delivered in connection with such assignment shall be paid or delivered to
Landlord, shall be and remain the exclusive property of Landlord and shall not
constitute property of Tenant or of the estate of Tenant within the meaning of
the Bankruptcy Code. Any and all monies or other considerations constituting
Landlord's property under the preceding sentence not paid or delivered to
Landlord shall be held in trust for the benefit of the Landlord and promptly
paid or delivered to Landlord.

         C.  Any person or entity to which this lease is assigned pursuant to 
the provisions of the Bankruptcy Code, shall be deemed, without further act or
deed, to have assumed all of the obligations arising under this lease on and
after the date of such assignment. Any such assignee shall upon demand execute
and deliver to Landlord an instrument confirming such assumption.

         12. Fire and Casualty Damage.

         A.  Landlord agrees to maintain insurance covering the building of
which the premises are a part in an amount not less than eighty percent (80%)
(or such greater percentage as may be necessary to comply with the provisions of
any co-insurance clauses of the policy) of the replacement cost thereof,
insuring against the perils of Fire, Lightning, Extended Coverage, Vandalism and
Malicious Mischief, extended by Special Extended Coverage Endorsement to insure
against all other regulatory authority for the state in which the premises are
situated for use by

                                      -7-
<PAGE>   8



insurance companies admitted in such state for the writing of such insurance on
risks located within such state. Subject to the provisions of subparagraphs 12C,
12D and 12E below, such insurance shall be for the sole benefit of Landlord and
under its sole control. If, during the second calendar year after the
commencement date of this lease, or during any subsequent calendar year of the
primary term or any renewal or extension, Landlord's cost of maintaining such
insurance shall exceed Landlord's cost of maintaining such insurance for the
first calendar year or the term hereof, Tenant agrees to pay to Landlord, as
additional rental, the amount of such excess not to exceed $4,128.00 per year
(or in the event the premises constitute a portion of a multiple occupancy
building, Tenant's full proportionate share of such excess). The first calendar
year shall be the year in which the lease commences. Said payments shall be made
to Landlord within ten (10) days after presentation to Tenant of Landlord's
statement setting forth the amount due. Any payment to be made pursuant to this
subparagraph A with respect to the year in which this lease commences or
terminates shall bear the same ratio to the payment which would be required to
be made for the full year as the part of such year covered by the term of this
lease bears to a full year. (See additional provision #38.)

         B. If the buildings situated upon the premises should be damaged or
destroyed by fire, tornado or other casualty, Tenant shall give immediate
written notice thereof to Landlord.

         C. If the buildings situated upon the premises should be totally
destroyed by fire, tornado or other casualty, or if they should be so damaged
thereby that rebuilding or repairs cannot in Landlord's reasonable estimation be
completed within one hundred twenty (120) days after the date upon which
Landlord is notified by Tenant of such damage, this lease shall terminate and
the rent shall be abated during the unexpired portion of this lease, effective
upon the date of the occurrence of such damage.

         D. If the buildings situated upon the premises should be damaged by any
peril covered by the insurance to be provided by Landlord under subparagraph 12A
above, but only to such extent that rebuilding or repairs can in Landlord's
reasonable estimation be completed within one hundred twenty (120) days after
the date upon which Landlord is notified by Tenant of such damage, this lease
shall not terminate, and Landlord shall at its sole cost and expense thereupon
proceed with reasonable diligence to rebuild and repair such buildings to
substantially the condition in which they existed prior to such damage, except
that Landlord shall not be required to rebuild, repair or replace any part of
the partitions, fixtures, additions and other improvements which may have been
placed in, on or about the premises by Tenant and except that Landlord may elect
not to rebuild if such damage occurs during the last year of the term of the
lease exclusive of any option which is unexercised at the time of such damage.
If the premises are untenantable in whole or in part following such damage, the
rent payable hereunder during the period in which they are untenantable shall be
reduced to such extent as may be fair and reasonable under all of the
circumstances. In the event that Landlord should fail to complete such repairs
and rebuilding within one hundred twenty (120) days after the date upon which
Landlord is notified by Tenant of such damage, Tenant may at its option
terminate this lease by delivering written notice of termination to Landlord as
Tenant's exclusive remedy, whereupon all rights and obligations hereunder shall
cease and terminate.

                                      -8-
<PAGE>   9



         E.  Notwithstanding anything herein to the contrary, in the event the
holder of any indebtedness secured by a mortgage or deed of trust covering the
premises requires that the insurance proceeds be applied to such indebtedness,
then Landlord shall have the right to terminate this lease by delivering written
notice of termination to Tenant within fifteen (15) days after such requirement
is made by any such holder, whereupon all rights and obligations hereunder shall
cease and terminate.

         F.  Each of Landlord and Tenant hereby releases the other from any loss
or damage to property caused by fire or any other perils insured in policies of
insurance covering such property, even if such loss or damage shall have been
caused by the fault or negligence of the other party, or anyone for whom such
other party may be responsible. Each of the Landlord and Tenant agrees that it
will request its insurance carriers to include in its policies such a clause or
endorsement. If extra cost shall be charged therefore, each party shall advise
the other thereof and of the amount of the extra cost, and the other party, at
its election, may pay the same, but it shall not be obligated to do so.

         13. Liability. Landlord shall not be liable to Tenant or Tenant's
employees, agents, patrons or visitors, or to any other person whomsoever, for
any injury to person or damage to property on or about the premises, resulting
from and or caused in part or whole by the negligence or misconduct of Tenant,
its agents, servants or employee of any other person entering upon the premises,
or caused by the buildings and improvements located on the premises becoming out
of repair, or caused by leakage of gas, oil, water or steam or by electricity
emanating from the premises, or due to any cause whatsoever, and Tenant hereby
covenants and agrees that it will at all times indemnify and hold safe and
harmless the property, the Landlord (including without limitation the trustee
and beneficiaries if Landlord is a trust), Landlord's agents and employees from
any loss, liability, claims, suits, costs, expenses, including without
limitation attorney's fees and damages, both real and alleged, arising out of
any such damage or injury, except injury to persons or damage to property the
cause of which is the negligence of Landlord or the failure of Landlord to
repair any part of the premises which Landlord is obligated to repair and
maintain hereunder within a reasonable time after the receipt of written notice
from Tenant of needed repairs. Tenant shall procure and maintain throughout the
term of this lease a policy or policies of insurance, at its sole cost and
expense, insuring both Landlord and Tenant against all claims, demands or
actions arising out of or in connection with: (i) the premises; (ii) the
condition of the premises; (iii) Tenant's operations in and maintenance and use
of the premises; and (iv) Tenant's liability assumed under this lease, the
limits of such policy or policies to be in the amount of not less than
$1,000,000.00 per occurrence in respect to injury to persons (including death),
and in the amount of not less than $100,000.00 per occurrence in respect to
property damage or destruction, including loss of use thereof. All such policies
shall be procured by Tenant from responsible insurance companies satisfactory to
Landlord. Certificates evidencing of such policies, together with receipt
evidencing payment of premiums therefor, shall be delivered to Landlord prior to
the commencement date of this lease. Not less than fifteen (15) days prior to
the expiration date of any such policies, certificates evidencing the renewals
thereof (bearing notations evidencing the payment of renewal premiums) shall be
delivered to Landlord. Such policies shall further provide that not less than


                                      -9-
<PAGE>   10



thirty (30) days written notice shall be given to Landlord before such policy
may be cancelled or changed to reduce insurance provided thereby. (See
Additional Provision #39.)

         14. Condemnation.

         A.  If the whole or any substantial part of the premises should be
taken for any public or quasi-public use under governmental law, ordinance or
regulation, or by right of eminent domain, or by private purchase in lieu
thereof and the taking would prevent or materially interfere with the use of the
premises for the purposes for which they are being used, this lease shall
terminate and the rent shall be abated during the unexpired portion of this
lease, effective when the physical taking of said premises shall occur.

         B.  If part of the premises shall be taken for any public or
quasi-public use under any governmental law, ordinance or regulation, or by
right of eminent domain, or by private purchase in lieu thereof, and this lease
is not terminated as provided in the subparagraph above, this lease shall not
terminate but the rent payable hereunder during the unexpired portion of this
lease shall be reduced to such extent as may be fair and reasonable under all of
the circumstances.

         C.  All compensation awarded for any taking (or the proceeds of private
sale in lieu thereof) of the premises, buildings or other improvements, or any
part thereof, shall be the property of Landlord and Tenant hereby assigns its
interest in any such award to Landlord; provided, however, Landlord shall have
no interest in any award made to Tenant for loss of business or for the taking
of Tenant's fixtures and improvements if a separate award for such items is made
to Tenant.

         15. Holding Over. Tenant will, at the termination of this lease by
lapse of time or otherwise, yield up immediate possession to Landlord with all
repairs and maintenance required herein to be performed by Tenant completed. If
Landlord agrees in writing that Tenant may hold over after the expiration or
termination of this lease, unless the parties hereto otherwise agree in writing
on the terms of such holding over, the hold over tenancy shall be subject to
termination by Landlord at any time upon not less than five (5) days advance
written notice, or by Tenant at any time upon not less than thirty (30) days
advance written notice, and all of the other terms and provisions of this lease
shall be applicable during that period, except that Tenant shall pay Landlord
from time to time upon demand, as rental for the period of any hold over, an
amount equal to double the rent in effect on the termination date, computed on a
daily basis for each day of the hold over period. No holding over by Tenant,
whether with or without consent of Landlord, shall operate to extend this lease
except as otherwise expressly provided. The preceding provisions of this
paragraph 15 shall not be construed as consent for Tenant to hold over.

         16. Quiet Enjoyment. Landlord covenants that it now has good title to
the premises, free and clear of all liens and encumbrances, excepting only the
lien for current taxes not yet due, such mortgage or mortgages as are permitted
by the terms of this lease, zoning ordinances and other building and fire
ordinances and governmental regulations relating to the use of such property,
and easements, restrictions and other conditions of record. Landlord represents
and warrants that it has full right and authority to enter into this lease and
that Tenant, upon paying the rental herein set forth


                                      -10-
<PAGE>   11


and performing its other covenants and agreements herein set forth, shall
peaceably and quietly have, hold and enjoy the premises for the term hereof
without hindrance or molestation from Landlord, subject to the terms and
provisions of this lease.

         17. Events of Default. The following events shall be deemed to be
events of default by Tenant under this lease:

         A.  Tenant shall fail to pay any installment of the rent herein 
reserved when due, or any other payment or reimbursement to Landlord required
herein when due, and such failure shall continue for a period of ten (10) days
from the date such payment was due.

         B.  Tenant or any guarantor of Tenant's obligations hereunder shall
generally not pay its debts as they become due or shall admit in writing its
inability to pay its debts or shall make a general assignment for the benefit of
creditors, or Tenant or any such guarantor shall commence any case, proceeding
or other action seeking to have an order for relief entered on its behalf as a
debtor or to adjudicate it as bankrupt or insolvent, or seeking reorganization,
arrangement, adjustment, liquidation, dissolution, or composition of it or its
debts under any law relating to bankruptcy, insolvency, reorganization or relief
of debtors or seeking appointment of a receiver, trustee, custodian or other
similar official for it or for all or of any substantial part of its property,
or Tenant or any such guarantor shall take any action to authorize or in
contemplation of any of the actions set forth above in this paragraph, or

         C.  Any case, proceeding or other action against Tenant or any
guarantor of Tenant's obligations hereunder shall be commenced seeking to have
an order for relief entered against it as debtor or to adjudicate it as bankrupt
or insolvent, or seeking reorganization, arrangement, adjustment, liquidation,
dissolution or composition of it or its debts under any law relating to
bankruptcy, insolvency, reorganization or relief of debtors, or seeking
appointment of a receiver, trustee, custodian or other similar official for it
or for all or any substantial part of its property.

         D.  A receiver to trustee shall be appointed for all or substantially
all of the assets of Tenant.

         E.  Tenant shall desert or vacate any substantial portion of the
premises.

         F.  Tenant shall fail to discharge any lien placed upon the premises in
violation of Paragraph 22 hereof within twenty (20) days after any such lien or
encumbrance is filed against the premises.

         G.  Tenant shall fail to comply with any term, provision or covenant of
this lease (other than the foregoing in this Paragraph 17), and shall not cure
or commence to cure and diligently pursue to completion such failure within
twenty (20) days after written notice thereof to Tenant.



                                      -11-
<PAGE>   12



         H.  Tenant shall fail to continuously operate its business at the
premises for the permitted use set forth in Paragraph 3 whether or not Tenant is
in default of the rental payments due under this lease.

         18. Remedies.

         A.  Upon the occurrence of any of such events of default described in
Paragraph 17 hereof, Landlord shall have the option to pursue any one or more of
the following remedies without any notice or demand whatsoever:

             (1)          Terminate this lease, in which event Tenant shall
                          immediately surrender the premises to Landlord, and if
                          Tenant fails so to do, Landlord may, without prejudice
                          to any other remedy which it may have for possession
                          or arrearage in rent, enter upon and take possession
                          of the premises and expel or remove Tenant and any
                          other person who may be occupying such premises or any
                          part thereof, by force if necessary, without being
                          liable for prosecution or any claim of damages
                          therefore.

             (2)          Enter upon and take possession of the premises and
                          expel or remove Tenant and any other person who may be
                          occupying such premises or any part thereof, by force
                          if necessary, without being liable for prosecution or
                          any claim for damages therefore.

             (3)          Enter upon the Premises, by force if necessary,
                          without being liable for prosecution or any claim for
                          damages therefore, and do whatever Tenant is obligated
                          to do under the terms of this lease; and Tenant agrees
                          to reimburse Landlord on demand for any expenses which
                          Landlord may incur in thus effecting the compliance
                          with Tenant's obligations under this Lease, and Tenant
                          further agrees that Landlord shall not be liable for
                          any damages resulting to the Tenant from such action,
                          whether caused by the negligence of Landlord or
                          otherwise.

             (4)          Alter all locks and other security devices at the
                          premises without terminating this lease.

         B.  In the event Landlord may elect to regain possession of the
premises by a forcible detainer proceeding, Tenant hereby specifically waives
any statutory notice which may be required prior to such proceeding, and agrees
that Landlord's execution of this lease is, in part, consideration of this
waiver.

         C.  In the event Tenant fails to pay any installment of rent hereunder
as and when such installment is due, to help defray the additional cost to
Landlord for processing such late payments Tenant shall pay to Landlord on
demand a late charge in an amount equal to five (5%) percent of such
installment; and the failure to pay such amount within five (5) days after
demand therefore




                                      -12-
<PAGE>   13

shall be an event of default hereunder. The provision for such late charge shall
be in addition to all of Landlord's other rights and remedies hereunder or at
law and shall not be construed as liquidated damages or as limiting Landlord's
remedies in any manner.

         D.  In the event Tenant's check, given to Landlord in payment, is
returned by the bank for non-payment, Tenant agrees to pay all expenses incurred
by Landlord as a result thereof.

         E.  Exercise by Landlord of any one or more remedies hereunder granted
or otherwise available shall not be deemed to be an acceptance or surrender of
the premises by Tenant, whether by agreement or by operation of law, it being
understood that such surrender can be effected only by the written agreement of
Landlord and Tenant. No such alteration of locks or other security devices and
no removal or other exercise of dominion by Landlord over the property of Tenant
or others at the premises shall be deemed unauthorized or constitute a
conversion, Tenant hereby consenting, after any event of default, to the
aforesaid exercise of dominion over Tenant's property within the premises. All
claims for damages by reason of such re-entry and/or repossession and/or
alteration of locks or other security devices are hereby waived, as are all
claims for damages by reason of any distress warrant, forcible detainer
proceedings, sequestration proceedings or other legal process. Tenant agrees
that any re-entry by Landlord may be pursuant to judgment obtained in forcible
detainer proceedings or other legal proceedings or without the necessity for any
legal proceedings, as Landlord may elect, and Landlord shall not be liable for
trespass or otherwise.

         F.  Omitted.

         G.  In the event that Landlord elects to repossess the premises without
terminating the lease, or in the event Landlord elects to terminate the lease,
then Tenant, at Landlord's option, shall be liable for and shall pay to
Landlord, at the address specified for notice to Landlord herein, all rental and
other indebtedness accrued to the date of such repossession, plus rental
required to be paid by Tenant to Landlord during the remainder of the lease term
until the date of expiration of the term as stated in Paragraph 1 diminished by
any net sums thereafter received by Landlord through reletting the premises
during said period (after deducting expenses incurred by Landlord as provided in
subparagraph 18H below). In no event shall Tenant be entitled to any excess of
any rental obtained by reletting over and above the rental herein reserved.
Actions to collect amounts due by Tenant to Landlord under this subparagraph may
be brought from time to time, on one or more occasions, without the necessity of
Landlord's waiting until expiration of the lease term.

         H.  In case of any event of default or breach by Tenant, or threatened
or anticipatory breach or default, Tenant shall also be liable for and shall pay
to Landlord, at the address specified for notice to Landlord herein, in addition
to any sum provided to be paid above, brokers' fees incurred by Landlord in
connection with reletting the whole or any part of the premises; the costs of
removing and storing Tenant's or other occupant's property; the costs of
repairing, altering, remodeling or otherwise putting the premises into condition
acceptable to a new tenant or tenants, and all reasonable expenses incurred by
Landlord in enforcing or defending Landlord's rights and/or remedies including
reasonable attorney's fees.




                                      -13-
<PAGE>   14

         I. In the event of termination or repossession of the premises for an
event of default, Landlord shall not have any obligation to relet or to attempt
to relet the premises, or any portion thereof; and in the event of reletting,
Landlord may relet the whole or any portion of the premises for any period to
any tenant and for any use and purpose.

         J. If Tenant should fail to make any payment or cure any default
hereunder within the time herein permitted, Landlord, without being under any
obligation to do so and without thereby waiving such default, may make such
payment and/or remedy such other default for the account of Tenant (and enter
the premises for such purpose), and thereupon Tenant shall be obligated to, and
hereby agrees, to pay Landlord upon demand, all costs, expenses and
disbursements (including reasonable attorney's fees) incurred by Landlord in
taking such remedial action.

         K. In the event that Landlord shall have taken possession of the
premises pursuant to the authority herein granted then Landlord shall have the
right to keep in place and use all of the furniture, fixtures and equipment at
the premises, including that which is owned by or leased to Tenant at all times
prior to any foreclosure thereon by Landlord or repossession thereof by any
lessor thereof or third party having a lien thereon. Landlord shall also have
the right to remove from the premises (without the necessity of obtaining a
distress warrant, writ of sequestration or other legal process) all or any
portion of such furniture, fixtures, equipment and other property located
thereon and to place same in storage at any premises within the County in which
the premises is located; and in such event, Tenant shall be liable to Landlord
for costs incurred by Landlord in connection with such removal and storage.
Landlord shall also have the right to relinquish possession of all or any
portion of such furniture, fixtures, equipment and other property to any person
("Claimant") claiming to be entitled to possession thereof who presents to
Landlord a copy of any instrument represented to Landlord by Claimant to have
been executed by Tenant (or any predecessor Tenant) granting Claimant the right
under various circumstances to take possession of such furniture, fixtures,
equipment or other property, without the necessity on the part of Landlord to
inquire into the authenticity of said instrument's copy of Tenant's or Tenant's
predecessor's signature(s) thereon and without the necessity of Landlord making
any nature of investigation or inquiry as to the validity of the factual or
legal basis upon which Claimant purports to act; and Tenant agrees to indemnity
and hold Landlord harmless from all cost, expense, loss, damage and liability
incident to Landlord's relinquishment of possession of all or any portion of
such furniture, fixtures, equipment or other property to Claimant. The rights of
Landlord herein stated shall be in addition to any and all other rights which
Landlord has or may hereafter have at law or in equity; and Tenant stipulates
and agrees that the rights herein granted Landlord are commercially reasonable.

         L. Notwithstanding anything in this lease to the contrary, all amounts
payable by Tenant to or on behalf of Landlord under this lease, whether or not
expressly denominated as rent, shall constitute rent for the purposes of the
Bankruptcy Code, 11 U.S.C. ss.502(b)(7).

         M. This is a contract under which applicable law excuses Landlord from
accepting performance from or rendering performance to any person or entity
other than Tenant within the meaning of the Bankruptcy Code, 11 U.S.C.
ss.365(c), 365(e)(2).

         N.  If this Lease is assigned to any person or entity pursuant to the
provisions of the Bankruptcy Code, any and all monies or other considerations
payable or otherwise to be delivered in connection with such assignment shall be
paid or delivered to Landlord, shall be and remain the exclusive property of
Landlord and shall not constitute property of Tenant or of the estate of Tenant
within the meaning of the Bankruptcy Code. Any and all monies or other
considerations constituting Landlord's property under the preceding sentence not
paid or delivered to Landlord shall be held in trust for the benefit of Landlord
and be promptly paid or delivered to Landlord.

         O.  Any person or entity to which this lease is assigned pursuant to 
the provisions of the Bankruptcy Code, shall be deemed, without further act or
deed, to have assumed all of the obligations arising under this Lease on and
after the date of such assignment. Any such assignee shall upon demand execute
and deliver to Landlord an instrument confirming such assumption.

         19. Omitted.

         20. Mortgages. Tenant accepts this lease subject and subordinate to any
mortgage(s) and/or deed(s) of trust now or at any time hereafter constituting a
lien or charge upon the premises or the improvements situated thereon, provided
however, that if the mortgagee, trustee, or holder of any such mortgage or deed
of trust elects to have Tenant's interest in this lease superior to any such
instrument, then by notice to Tenant from such mortgagee, trustee or holder,
this lease shall be deemed superior to such lien, whether this lease was
executed before or after said mortgage or deed of trust. Tenant shall at any
time hereafter on demand execute any instruments, releases or other documents
which may be required by any mortgagee for the purpose of subjecting and
subordinating this lease to the lien of any such mortgage.

         21. Landlord's Default. In the event Landlord should become in default
in any payments due on any such mortgage described in Paragraph 20 hereof or in
the payment of taxes or any other items which might become a lien upon the
premises and which Tenant is not obligated to pay under the terms and provisions
of this lease, Tenant is authorized and empowered after giving Landlord five (5)
days prior written notice of such default and Landlord's failure to cure such
default, to pay any such items for and on behalf of Landlord, and the amount of
any item so paid by Tenant for or on behalf of Landlord, together with any
interest or penalty required to be paid in connection therewith, shall be
payable on demand by Landlord to Tenant; provided however, that Tenant shall not
be authorized and empowered to make any payment under the terms of this
Paragraph 21 unless the item paid shall be superior to Tenant's interest
hereunder. In the event Tenant pays any mortgage debt in full, in accordance
with this paragraph, it shall, at its election, be entitled to the mortgage
security by assignment or subrogation.

         22. Mechanics Liens and Other Taxes.

         A.  Tenant shall have no authority, express or implied, to create or
place any lien or encumbrance of any kind or nature whatsoever upon, or in any
manner to bind the interests of Landlord in the premises or to charge the
rentals payable hereunder for any claim in favor of any person dealing with
Tenant, including those who may furnish materials or perform labor for any


                                      -15-
<PAGE>   16



construction or repairs, and each such claim shall affect and each such lien
shall attach to, if at all, only the leasehold interest granted to Tenant by
this instrument. Tenant covenants and agrees that it will pay or cause to be
paid all sums legally due and payable by it on account of any labor performed or
materials furnished in connection with any work performed on the premises on
which any lien is or can be validly and legally asserted against its leasehold
interest in the premises or the improvements thereon and that it will save and
hold Landlord harmless from any and all loss, cost or expense based on or
arising out of asserted claims or liens against the leasehold estate or against
the right, title and interest of the Landlord in the premises or under the terms
of this lease. Tenant agrees to give Landlord immediate written notice if any
lien or encumbrance is placed on the premises.

         B.  Tenant shall be liable for all taxes levied or assessed against
personal property, furniture or fixtures placed by Tenant in the premises. If
any such taxes for which Tenant is liable are levied or assessed against
Landlord or Landlord's property and if Landlord elects to pay the same or if the
assessed value of Landlord's property is increased by inclusion of personal
property, furniture or fixtures placed by Tenant in the premises, and Landlord
elects to pay the taxes based on such increase, Tenant shall pay to Landlord
upon demand that part of such taxes.

         23. Omitted.

         24. Certain Rights Reserved to Landlord. Landlord reserves and may
exercise the following rights without affecting Tenant's obligations hereunder:
(a) to change the name, street address, or suite numbers of the building; (b) to
install or maintain a sign or signs on the exterior of the building.

         25. Notices. Each provision of this instrument or of any applicable
governmental laws, ordinances, regulations and other requirements with reference
to the sending, mailing or delivery of any notice or the making of any payment
by Landlord to Tenant or with reference to the sending, mailing or delivery of
any notice or the making of any payment by Tenant to Landlord shall be deemed to
be complied with when and if the following steps are taken:

         A.  All rent and other payments required to be made by Tenant to
Landlord hereunder shall be payable to Landlord at the address hereinbelow set
forth or at such other address as Landlord may specify from time to time by
written notice delivered in accordance herewith. Tenant's obligations to pay
rent and any other amounts to Landlord under the terms of this lease shall not
be deemed satisfied until such rent and other amounts have been actually
received by Landlord.

         B.  All payments required to be made by Landlord to Tenant hereunder
shall be payable to Tenant at the address hereinbelow set forth, or at such
other address within the continental United States as Tenant may specify from

        LANDLORD:                                 TENANT:

PEACHTREE CROSSINGS BUSINESS            HAYES MICROCOMPUTER PRODUCTS,

         26. Hazardous Waste. The term "Hazardous Substances," as used in this
lease shall mean pollutants, contaminants, toxic or hazardous wastes, or any
other substances, the removal of which is required or the use of which is
restricted, prohibited or penalized by any "Environmental Law," which term shall
mean any federal, state or local law or ordinance relating to pollution or
protection of the environment. Tenant hereby agrees that (i) no activity will be
conducted on the premises that will produce any Hazardous Substance, except for
such activities that are part of the ordinary course of Tenant's business
activities that are part of the ordinary course of Tenant's business (the
"Permitted Activities") provided said Permitted Activities are conducted in
accordance with all Environmental Laws and have been approved in advance in
writing by Landlord; (ii) the premises will not be used in any manner for the
storage of any Hazardous Substances except for the temporary storage of such

diligently undertaken pursuant to all Environmental Laws. If, at any time during


                                      -17-
<PAGE>   18


or after the term of the lease, the premises is found to be so contaminated or
subject to said conditions, Tenant agrees to indemnify and hold Landlord
harmless from all claims, demands, actions, liabilities, costs, expenses,
damages and obligations of any nature arising from or as a result of the use of
the premises by Tenant. The foregoing indemnification shall survive the
termination or expiration of this lease. See Additional Provision #40.

         27. Miscellaneous.

         A.  Words of any gender used in this lease shall be held and construed
to include any other gender, and words in the singular number shall be held to
include the plural, unless the context otherwise requires.

         B.  In the event the premises constitutes a portion of a multiple
occupancy building or building complex, Tenant's "proportionate share," as used
in this lease, shall mean a fraction, the numerator of which is the space
contained in the premises and the denominator of which is the entire space
contained in the building or building complex.

         C.  The terms, provisions and covenants and conditions contained in 
this lease shall apply to, inure to the benefit of, and be binding upon the
parties hereto and upon their respective heirs, legal representatives,
successors and permitted assigns, except as otherwise herein expressly provided.
Landlord shall have the right to assign any of its rights and obligations under
this lease. Each party agrees to furnish to the other, promptly upon demand, a
corporate resolution, proof of due authorization by partners, or other
appropriate documentation evidencing the due authorization of such party to
enter into this lease.

         D.  The captions inserted in this lease are for convenience only and in
no way define, limit or otherwise describe the scope or intent of this lease, or
any provision hereof, or in any way affect the interpretation of this lease.

         E.  Tenant agrees from time to time within ten (10) days after request
of Landlord, to deliver to Landlord, or Landlord's designee a certificate of
occupancy (if applicable) to an estoppel certificate stating that this lease is
in full force and effect, the date to which rent has been paid, the unexpired
term of this lease and such other matters pertaining to this lease as may be
requested by Landlord. It is understood and agreed that Tenant's obligation to
furnish such estoppel certificates in a timely fashion is a material inducement
for Landlord's execution of this lease.

         F.  This lease may not be altered, changed or amended except by an
instrument in writing signed by both parties hereto.

         G.  All obligations of Tenant hereunder not fully performed as of the
expiration or earlier termination of the term of this lease shall survive the
expiration or earlier termination of the term hereof, including without
limitation all payment obligations with respect to taxes and insurance and all
obligations concerning the condition of the premises. Upon the expiration or
earlier termination of the term hereof, and prior to Tenant vacating the
premises, Tenant shall pay to Landlord any


                                      -18-
<PAGE>   19



amount reasonably as necessary to put the premises, including without limitation
all heating and air conditioning systems and equipment therein, in good
condition and repair. Tenant shall also, prior to vacating the premises, pay to
Landlord the amount of Tenant's obligation hereunder for real estate taxes and
insurance premiums for the year in which the lease expires or terminates. All
such amounts shall be used and held by Landlord for payment of such obligations
of Tenant hereunder, with Tenant being liable for any additional costs therefore
upon demand by Landlord, or with any excess to be returned to Tenant after all
such obligations have been determined and satisfied, as the case may be. Any
security deposit held by Landlord shall be credited against the amount payable
by Tenant under this Subparagraph 27G.

         H. If any clause or provision of this lease is illegal, invalid or
unenforceable under present or future laws effective during the term of this
lease, then and in that event, it is the intention of the parties hereto that
the remainder of this lease shall not be affected thereby, and it is also the
intention of the parties to this lease that in lieu of each clause or provision
of this lease that is illegal, invalid or unenforceable, there be added as a
part of this lease contract a clause or provision as similar in terms to such
illegal, invalid or unenforceable clause or provision as may be possible and be
legal, valid and enforceable.

         I. Because the premises are on the open market and are presently being
shown, this lease shall be treated as an offer with the premises being subject
to prior lease and such offer subject to withdrawal or non-acceptance by
Landlord or to other use of the premises without notice, and this lease shall
not be valid or binding unless and until accepted by Landlord in writing and a
fully executed copy delivered to both parties hereto.

         J. All references in this lease to "the date hereof" or similar
references shall be deemed to refer to the last date, in point of time, on which
all parties hereto have executed this lease.

         K. Time is of the essence of this lease and all of its provisions. This
lease in all respect shall be governed by the laws of the State of Georgia.

         L. No animals shall be brought into or kept in or about the building.

         M. Tenant agrees to comply with subdivision regulations, protective
covenants, or other restrictions of record that are applicable to the building
or building complex.

         N. The duties and obligations of Tenant herein shall be binding upon
all or any of them. The duties and obligations of Tenant shall run and extend
not only to the benefit of the Landlord, as named herein, but to the following,
at the option of the following or any of them (i) any person by, through or
under which Landlord derives the right to lease the premises; (ii) the owner of
the premises; and (ii) holders of mortgage or rent assignment interests in the
premises, as their respective interests may appear; provided, however, nothing
contained herein shall be construed to obligate Tenant to pay rent to any person
other than the Landlord until such time as Tenant has been given written notice
of either an exercise of a rent assignment or the succession of some other party
to the interests of Landlord.

                              ADDITIONAL PROVISIONS


         29. If any interest shall be earned on the Tenant's security deposit
provided for in Paragraph 2B hereof, such interest shall be the property of, and
shall be retained by, the Landlord without obligation to Tenant to account
therefore.

         30. Tenant expressly agrees that the obligations incurred by Landlord
shall not constitute personal obligations of the officers, directors, trustees,
partners, joint venturers, members, stockholders, or other principals or
representatives of the Landlord. Tenant further agrees that it shall have
recourse against Landlord only to the extent of Landlord's assets for the
satisfaction of the obligations of the Landlord created under this Lease, and
not against the assets of such entity's officers, directors, trustees, partners,
joint venturers, members, stockholders, principals or representatives.

         31. Landlord covenants and agrees that if Tenant shall desert, vacate
or abandon the leased premises prior to the expiration or early termination of
the Lease Agreement, Landlord shall use reasonable efforts to lease the leased
premises to another Tenant.

         32. While this Lease is in full force and effect, provided Tenant is
not in default of the terms, covenants and conditions thereof, Tenant shall have
the sole right or option to extend the original term of this Lease Agreement for
a further consecutive term of twelve (12) months. Such extension or renewal of
the original term shall be on the same terms, covenants and conditions as
provided in the original term with the rent at the current rate at the time of
option. Notice of Tenant's intention to exercise this right or option must be
given in writing to Landlord on or before March 1, 1998, or the option contained
in this provision shall become null and void and of no effect. The right of
option to extend the original term of this Lease Agreement provided to Tenant
herein shall be for the exclusive benefit of the Tenant and shall terminate upon
the subletting of all or any part of the premises or assignment of this Lease.

         33. Notwithstanding any terms or provisions of this Lease which may be
construed to the contrary, Landlord and Tenant agree that Landlord will conduct
common area maintenance on the premises and grounds around the premises. Said
common area maintenance will include, but not be limited to, fire sprinkler
water charges, irrigation, lawn maintenance, security patrol and outside light
maintenance. The cost of said common area maintenance will be paid on a monthly
basis by Tenant and will amount to approximately SEVEN HUNDRED FORTY AND NO/100
DOLLARS ($740.00) per month. Landlord agrees that the monthly amount paid by
Tenant shall be capped at a compounded rate of ten percent (10%) per annum.
However, in the event Landlord elects to discontinue services or elects to
provide additional services as may be necessary under Paragraph 6 of this lease,
the monthly common area maintenance charge will be adjusted to reflect the
change in services provided.

         34. Landlord hereby covenants and agrees to use reasonable efforts to
cause any holder of a deed to secure debt or mortgage now or at any time
hereafter constituting a lien or charge upon


<PAGE>   22


ADDITIONAL PROVISIONS CONT.


the premises or the improvements situated thereon to enter into a
non-disturbance agreement pursuant to which such holder shall agree that if it
shall acquire the ownership of the premises or the improvements situated thereon
through the exercise of a power of sale or other remedy provided for in such
deed to secure debt or mortgage, it shall permit Tenant to remain in possession
of the premises in accordance with the terms and provisions of this lease,
provided that Tenant shall continue to perform its duties and obligations
hereunder.

         35. Landlord and Tenant shall each provide the other with certificates
evidencing the issuance of all policies of insurance required to be maintained
by them under the terms and provisions of this Lease. Such certificates shall be
so provided prior to the commencement date and, thereafter, not less than
fifteen (15) days prior to the expiration date of such policies.

         36. Notwithstanding the provisions of Paragraph 3 herein, provided this
Lease Agreement is in full force and effect and Tenant is not in default of the
terms, covenants, and conditions thereof, Tenant shall have the sole right or
option to cancel this Lease Agreement at the end of the forty- eighth (48th)
month of the lease term by: (1) providing Landlord with prior written notice of
its desire to cancel this Lease Agreement on or before March 1, 1997, and (2)
simultaneously depositing with Landlord a cancellation fee to Landlord of ELEVEN
THOUSAND SIX HUNDRED FORTY-FIVE AND NO/100 DOLLARS ($11,645.00). Failure by
Tenant to provide said written notice and cancellation fee on or before March 1,
1997 shall render this right or option null and void, thus rendering this Lease
Agreement in full force through the original sixty (60) month lease term. The
right of option to cancel this Lease Agreement shall be for the exclusive
benefit of the Tenant and shall terminate upon the subletting of all or any part
of the premises or assignment of this Lease.

         37. Notwithstanding the provisions of Paragraph 7 hereof, Tenant shall
have the option to remove the following improvements from the premises by the
date of termination of this Lease or upon earlier vacating of the premises
provided Tenant shall restore the premises to their original condition with
consideration for normal wear and tear. All such removals and restoration shall
be accomplished in a good workmanlike manner so as not to damage the primary
structure or structural qualities of the building and other improvements
situated on the premises:

             (1)          Security Systems (e.g. access control units, CCTV
                          equipment, magnetic lock sets, internal intercoms,
                          electric lock sets, etc.)

             (2)          Support equipment for specialized manufacturing.

             (3)          Life Safety/Control Panel.

             (4)          Telephone switching units.

             (5)          Air compressor units to support operations.

                          self contained units-not roof units).

         38. Notwithstanding the provisions of Paragraph 12 herein, Landlord
agrees to name Tenant as additional insured subject to the rights of the
mortgage holder on the insurance covering the building of which the premises are
a part.

         39. Notwithstanding the provisions of Paragraph 13 herein, Tenant shall
indemnify Landlord, Landlord's agents and employees from any loss as detailed in
Paragraph 13, however, Tenant shall only be responsible for those costs that are
not insured by Tenant's insurance policy or policies.

         40. Notwithstanding Paragraph 26 hereof, Landlord represents and
warrants that to the best of its knowledge and belief, there is no condition on
the premises which currently could be considered as a violation of any
Environmental Law and that to the best of its knowledge and belief no Hazardous
Substances are present in any form on or around the premises.

                           LOAN AND SECURITY AGREEMENT


         THIS LOAN AND SECURITY AGREEMENT is made on December 21, 1995, between
the undersigned Borrower and the undersigned Lender concerning loans and other
credit accommodations to be made by Lender to Borrower.

SECTION 1.  PARTIES

         1.1      The "BORROWER" is Hayes Microcomputer Products, Inc., a
Georgia corporation, and its successors and assigns, which has its chief
executive office and principal place of business at the address shown on Section
10.6(b).

         1.2      The "LENDER" is The CIT Group/Credit Finance, Inc. and its
successors and assigns.

SECTION 2.  LOANS AND OTHER CREDIT ACCOMMODATIONS

         2.1      Revolving Loans. Lender shall, subject to the terms and
conditions contained herein and in the Conditions Precedent Rider attached
hereto (the "CONDITIONS PRECEDENT RIDER"), make revolving loans to Borrower
("REVOLVING LOANS") in amounts requested by Borrower from time to time, but not
in excess of the Net Availability existing immediately prior to the making of
the requested loan and provided the requested loan would not cause the
outstanding Obligations to exceed the Maximum Credit.

         (a)      The "MAXIMUM CREDIT" is set forth in Section 10.1(a) hereof.

         (b)      The "GROSS AVAILABILITY" shall be calculated at any time as
                  the sum of:

                  (i)      the product obtained by multiplying the outstanding
                           amount of Eligible Domestic Accounts, net of all
                           taxes, discounts, allowances, and credits and
                           accruals for price protection, coop advertising and
                           warranty claims, given or claimed, by the Eligible
                           Domestic Accounts Percentage set forth in Section
                           10.1(b), plus

                  (ii)     the product obtained by multiplying the applicable
                           Eligible Domestic Inventory Percentage set forth in
                           Section 10.1(b) by the Value of Eligible Domestic
                           Inventory, but not to exceed the Inventory Sublimit
                           set forth in Section 10.1(c), plus

                  (iii)    the sum of the products obtained by (x) multiplying
                           the outstanding amount of Eligible UK Accounts, net
                           of all taxes, discounts, allowances, and credits and
                           accruals for price protection, coop advertising and
                           warranty claims, given or claimed, by the Eligible UK
                           Accounts Percentage as set forth in Section 10.1(b),
                           and (y)




<PAGE>   2



                  multiplying the Eligible UK Inventory Percentage set forth in
                  Section 10.1(b) by the Values of Eligible UK Inventory, but
                  not to exceed $4,000,000, plus

                  (iv)     the product obtained by multiplying the outstanding
                           amount of Eligible Foreign Accounts, net of all
                           taxes, discounts, allowances, and credits and
                           accruals for price protection, coop advertising and
                           warranty claims, given or claimed, by the Eligible
                           Foreign Accounts Percentage set forth in Section
                           10.1(b), but not to exceed $2,000,000,

                                    minus (subtract from the sum of clauses (i)
                                    through (iv) above)

                   (v)     the Reserves.

         (c)      "NET AVAILABILITY" shall be calculated at any time as an
amount equal to the Gross Availability minus the aggregate amount of all
then-outstanding Revolving Loans and Accommodations.

         (d)      "ELIGIBLE DOMESTIC ACCOUNTS" are accounts which arise in the
ordinary course of Borrower's business for goods sold or services rendered (but
excluding royalty and franchise receivables), and which are and remain
acceptable to Lender for lending purposes. General criteria for Eligible
Domestic Accounts are set forth below but may be revised from time to time by
Lender, in its sole judgment, on fifteen (15) days' prior written notice to
Borrower. Lender shall, in general, deem accounts to be Eligible Domestic
Accounts if: (1) such accounts arise from bona fide completed transactions and
have not remained unpaid for more than the number of days after the invoice date
set forth in Section 10.1(d); (2) the amounts of the accounts reported to Lender
are absolutely owing to Borrower and do not arise from sales on consignment,
guaranteed sale or other terms under which payment by the account debtors may be
conditional or contingent; (3) the account debtor's chief executive office and
principal place of business is located in the United States; (4) such accounts
do not arise from progress billings, retainages or bill and hold sales; (5)
there are no contra relationships, setoffs, counterclaims or disputes existing
with respect thereto and there are no other facts existing or threatened which
would impair or delay the collectibility of all or any portion thereof; (6) the
goods giving rise thereto were not at the time of the sale subject to any liens
except those permitted in this Agreement; (7) such accounts are not accounts
with respect to which the account debtor or any officer or employee thereof is
an officer, employee or agent of or is affiliated with Borrower, directly or
indirectly, whether by virtue of family membership, ownership, control,
management or otherwise; (8) such accounts are not accounts with respect to
which the account debtor is the United States or any State or political
subdivision thereof or any department, agency or instrumentality of the United
States, any State or political subdivision, unless there has been compliance
with the Assignment of Claims Act or any similar State or local law, if
applicable; (9) Borrower has delivered to Lender or Lender's representative such
documents as Lender may have


                                       -2-


<PAGE>   3



requested pursuant to Section 5.8 hereof in connection with such accounts and
Lender shall have received a verification of such account, satisfactory to it,
if sent to the account debtor or any other obligor or any bailee pursuant to
Section 5.4 hereof; (10) there are no facts existing or threatened which might
result in any adverse change in the account debtor's financial condition; (11)
such accounts owed by a single account debtor or its affiliates do not represent
more than twenty (20%) percent of all otherwise Eligible Domestic Accounts
(accounts excluded from Eligible Domestic Accounts solely by reason of this
subsection (11) shall nevertheless be considered Eligible Domestic Accounts to
the extent of the amount of such accounts which does not exceed twenty (20%)
percent of all otherwise Eligible Domestic Accounts); (12) such accounts are not
owed by an account debtor who is or whose affiliates are past due upon other
accounts owed to Borrower comprising more than fifty (50%) percent of the
accounts of such account debtor or its affiliates owed to Borrower; (13) such
accounts are owed by account debtors whose total indebtedness to Borrower does
not exceed the amount of any customer credit limits as established, and changed,
from time to time by Lender on notice to Borrower (accounts excluded from
Eligible Domestic Accounts solely by reason of this subsection (13) shall
nevertheless be considered Eligible Domestic Accounts to the extent the amount
of such accounts does not exceed such customer credit limit); and (14) such
accounts are owed by account debtors deemed creditworthy at all times by Lender.

         (e)      "ELIGIBLE DOMESTIC INVENTORY" is inventory owned by Borrower
which is and remains acceptable to Lender for lending purposes, is subject to
Lender's duly perfected, first priority security interest and no other lien
except liens described in SCHEDULE A hereto ("PERMITTED LIENS"), is not the
subject of any technology license agreement or any other agreement that
restricts or prohibits in any way Borrower's or Lender's right to sell or
otherwise dispose of any such inventory, and is located at one of the locations
owned or leased by Borrower in the United States of America that is set forth in
Section 10.6, other than a leased location with respect to which Lender has not
received from the owner thereof a landlord's waiver agreement in form and
substance satisfactory to Lender.

         (f)      "ELIGIBLE FOREIGN ACCOUNTS" are accounts which arise in the
ordinary course of Borrower's business for goods sold or services rendered,
which are and remain acceptable to Lender for lending purposes, which are owed
by account debtors having their chief executive office and principal place of
business in a country other than the United States or the United Kingdom, which
would be Eligible Domestic Accounts except for the location of the account
debtor's chief executive office or principal place of business, and with respect
to which the account debtor has procured and delivered to Borrower, and Borrower
has (if so requested by Lender) collaterally assigned to Lender all of
Borrower's rights under, an irrevocable standby letter of credit that is in form
acceptable to Lender, issued by a domestic U.S. bank acceptable to Lender in its
sole discretion and, if so requested by Lender, delivered to Lender. General
criteria for Eligible Foreign Accounts may be revised from time to time by
Lender, in its sole judgment, on fifteen (15) days' prior written notice to
Borrower.



                                       -3-


<PAGE>   4



         (g)      "ELIGIBLE UK ACCOUNTS" are accounts which arise in the
ordinary course of Borrower's business for goods sold or services rendered,
which are and remain acceptable to Lender for lending purposes, which are owing
by account debtors having their chief executive office and principal place of
business in the United Kingdom and which would otherwise qualify as Eligible
Domestic Accounts except for the location of the chief executive office or
principal place of business of the account debtors with respect thereto. General
criteria for Eligible UK Accounts may be revised from time to time by Lender, in
its sole judgment, on fifteen (15) days' prior written notice to Borrower.

         (h)      "ELIGIBLE UK INVENTORY" is inventory which, but for its
location in the United Kingdom, would constitute Eligible Domestic Inventory and
which is at all times subject to Lender's duly perfected, first priority
security interest and no other lien except a Permitted Lien.

         (i)      "VALUE" means the value of Borrower's inventory at any date,
determined by Lender at the lower of cost or market on such date, with the
market value of inventory being the liquidation value in continued use of such
inventory.

         (j)      Lender shall have a continuing right to deduct reserves
("RESERVES") in determining the Gross Availability, and to increase and decrease
such Reserves from time to time, if and to the extent that, in the exercise of
Lender's customary credit judgement, such Reserves which are necessary to
protect Lender against (1) any state of facts which constitute an Event of
Default or (2) against a loss that might result from any state of facts which
might reasonably be expected to have a Material Adverse Effect. Lender may, at
its option, implement Reserves by designating as ineligible a sufficient amount
of accounts or inventory which would otherwise be Eligible Domestic Accounts,
Eligible Foreign Accounts, or Eligible UK Accounts, or which would otherwise be
Eligible Domestic Inventory or Eligible UK Inventory, so as to reduce Gross
Availability by the amount of the intended Reserve. As used herein, the term
"MATERIAL ADVERSE EFFECT" shall mean the effect of any event, condition or state
of facts that is material with respect to (i) Borrower's business, operations,
properties or condition (financial or otherwise) or (ii) the quantity, quality
or value of any Collateral or the priority of Lender's liens therein, which in
either case materially impairs the ability of Borrower timely to pay and perform
the Obligations or the value of the Collateral.

         2.2      Term Loans.

         (a)      Subject to all of the terms and conditions contained herein
and in the Conditions Precedent Rider, Lender shall make two term loans to
Borrower (collectively, the "TERM LOANS" and individually a "TERM LOAN"), the
first of which ("TERM LOAN A") shall be in the amount of $2,608,000 and the
second of which ("TERM LOAN B") shall be in the amount of $7,500,000. Each of
the Term Loans shall be evidenced by a promissory note made by Borrower to the
order of Lender in substantially the form of Exhibits A and B, respectively
(each, as at any time amended or modified, a "TERM NOTE" and collectively the
"TERM NOTES") and shall be repaid, together with


                                       -4-


<PAGE>   5



interest as provided therein, in accordance with this Agreement and the Term
Note evidencing such Term Loan. The final maturity date of each Term Loan shall
be as set forth in Section 10.2.

         (b)      Borrower acknowledges and agrees that Lender shall have the
right to appraise, or cause an appraisal to be conducted of, all of Borrower's
machinery and equipment on an annual basis, and the cost of each such appraisal
shall be borne solely by Borrower. If based upon any such appraisal Lender
determines that the then outstanding principal balance of Term Loan A exceeds an
amount equal to eighty percent (80%) of the auction value of Eligible Equipment
(such excess being herein called the "TERM LOAN A OVERAGE"), then Lender, at its
option (and whether or not an Event of Default exists), may require Borrower to
increase the amount of each of the next six (6) monthly installments to become
due under Term Note A after such determination (or, if there are fewer than six
(6) remaining installments due, the number of remaining installments then due
under Term Note A) by an amount equal to such Term Loan A Overage divided by six
(6) (or, if fewer in number, the then remaining number of installments payable
under Term Note A). If requested to do so, Borrower shall execute and deliver to
Lender a modification of Term Note A, in form and content acceptable to Lender,
to reflect such increase in monthly principal payments thereunder. As used
herein, the term "ELIGIBLE EQUIPMENT" shall mean equipment owned by Borrower
(and not subject to any lease or conditional sale agreement) that is located at
one of the addresses in the United States of America shown in Section 10.6(c)
with respect of which Lender has received a landlord waiver from the applicable
owner of such premises and a mortgagee waiver from each mortgagee with respect
to such premises, is subject to Lender's duly perfected, first priority security
interest and no other lien that is not a Permitted Lien, is in good and
serviceable condition and is not obsolete or unmerchantable.

         (c)      Borrower acknowledges and agrees that Lender shall have the
right at any time or times to appraise, or cause an appraisal to be conducted
of, any or all of Borrower's intellectual property assets, including, without
limitation, all patents, trademarks, tradenames and copyrights ("Intellectual
Property"), and the cost of each such appraisal shall be borne solely by
Borrower. Each such appraisal shall be conducted by an appraiser selected by
Lender and shall employ an appraisal methodology consistent with that employed
by Marshall & Stevens of Philadelphia, Pennsylvania in its appraisal of such
assets prepared for Lender and Borrower and determined in October, 1995. Each
such appraisal shall take into account the effect, if any, upon the value of any
such Intellectual Property as collateral security for the Obligations of any
license or other agreement with respect to such assets entered into by Borrower
after the date hereof. If based upon any such appraisal Lender determines that
the unpaid balance of Term Loan B exceeds an amount equal to the Applicable
Percentage of the value of such Intellectual Property (such excess being herein
called the "TERM LOAN B OVERAGE"), then Lender, at its option (and whether or
not an Event of Default exists), may require Borrower to increase the amount of
each of the next six (6) monthly installments to become due under Term Note B
after such determination (or, if there are fewer than six (6) remaining
installments due, the number of remaining installments then due under Term Note
B) by an amount equal to such Term Loan B Overage divided by six (6) (or, a
fewer in number, the then remaining number of installments payable under Term
Note B). If requested to do so, Borrower will


                                       -5-


<PAGE>   6



promptly execute and deliver to Lender a modification of Term Note B, in form
and content acceptable to Lender, to reflect any such increase in monthly
principal payments thereunder. As used herein, the term "APPLICABLE PERCENTAGE"
shall mean 10% during the first Loan Year (as defined in Section 9.2), 9% during
the second Loan Year, and 8% at all times after the second Loan Year.

         (d)      If on any date that the Applicable Interest Margin as set
forth in Section 10.4(a) is 2- 1/8%, then Lender may, at its option, increase
the rate of monthly amortization on either or both of the Term Loans in such
amount as may be determined by CIT in its sole and absolute discretion (but in
no event to exceed, unless an Event of Default has occurred, two times the then
existing monthly amortization) and, if requested to do so, Borrower shall
promptly execute and deliver to Lender a modification of either or both of the
Term Notes, in form and content acceptable to Lender, to reflect such increase
in monthly principal payments thereunder.

         2.3      Accommodations.

         (a)      Lender may, in its sole discretion, issue or cause to be
issued, from time to time at Borrower's request and on terms and conditions and
for purposes satisfactory to Lender, credit accommodations consisting of letters
of credit, bankers' acceptances, merchandise purchase guaranties or other
guaranties or indemnities for Borrower's account ("ACCOMMODATIONS"). Borrower
shall execute and perform additional agreements relating to the Accommodations
in form and substance acceptable to Lender and the issuer of any Accommodations,
all of which shall supplement the rights and remedies granted herein. Any
payments made by Lender or any affiliate of Lender in connection with the
Accommodations shall constitute additional Revolving Loans to Borrower.

         (b)      In addition to the fees and costs of any issuer in connection
with issuing or administering Accommodations, Borrower shall pay monthly to
Lender, on the first day of each month, charges (the "ACCOMMODATION CHARGES") on
open Accommodations at the rate per annum set forth in Section 10.3(a).

         (c)      No Accommodation will be issued unless the full amount of the
Accommodation requested, plus fees and costs for issuance, is less than the Net
Availability existing immediately prior to the issuance of the requested
Accommodation, or if the requested Accommodation would cause the outstanding
Obligations to exceed the Maximum Credit, or cause the open amount of
Accommodations to exceed, at any time, the Accommodation sublimit set forth in
Section 10.3(b).

         (d)      All indebtedness, liabilities and obligations of any sort
whatsoever, however arising, whether present or future, fixed or contingent,
secured or unsecured, due or to become due, paid or incurred, arising or
incurred in connection with any Accommodation shall be included in the term
"OBLIGATIONS", as defined herein, and shall include, without limitation, (i) all
amounts due or which may become due under any Accommodation; (ii) all amounts
charged or chargeable to Borrower or


                                       -6-


<PAGE>   7



to Lender by any bank, other financial institution or correspondent bank which
opens, issues or is involved with such Accommodations; (iii) Lender's
Accommodation Charges and all fees, costs and other charges of any issuer of any
Accommodation; and (iv) all duties, freight, taxes, costs, insurance and all
such other charges and expenses which may pertain directly or indirectly to any
Obligations or Accommodations or to the goods or documents relating thereto.

         (e)      Borrower unconditionally agrees to indemnify, defend and hold
Lender harmless from any and all loss, claim or liability (including, without
limitation, reasonable attorneys' fees) arising from any transactions or
occurrences relating to any Accommodation established or opened for Borrower's
account, the Collateral relating thereto and any drafts or acceptances
thereunder, including, without limitation, any such loss or claim due to any
action taken by an issuer of any Accommodation. Borrower further agrees to
indemnify and hold Lender harmless for any errors or omissions in connection
with the Accommodations, whether caused by Lender, by the issuer of any
Accommodation or otherwise. Borrower's unconditional obligation to indemnify and
hold Lender harmless under this provision shall not be modified or diminished
for any reason or in any manner whatsoever, except for Lender's gross negligence
or wilful misconduct. Borrower agrees that any charges made to Lender by any
issuer of any Accommodation shall be conclusive on Borrower and may be charged
to Borrower's account.

         (f)      Lender shall not be responsible for: the conformity of any
goods to the documents presented; the validity or genuineness of any documents;
delay, default, or fraud by the Borrower or shipper and/or anyone else in
connection with the Accommodations or any underlying transaction; or any act or
failure to act, or any delay in acting or negligence in the issuance of any
letter of credit.

         (g)      Borrower agrees that any action taken by Lender, if taken in
good faith, or any action taken by an issuer of any Accommodation, under or in
connection with any Accommodation, shall be binding on Borrower and shall not
create any resulting liability to Lender. In furtherance thereof, Lender shall
have the full right and authority to clear and resolve any questions of
non-compliance of documents; to give any instructions as to acceptance or
rejection of any documents or goods; to execute for Borrower's account any and
all applications for steamship or airway guarantees, indemnities or delivery
orders; to grant any extensions of the maturity of, time of payment for, or time
of presentation of, any drafts, acceptances, or documents; and to agree to any
amendments, renewals, extensions, modifications, changes or cancellations of any
of the terms or conditions of any of the applications or Accommodations. All of
the foregoing actions may be taken in Lender's sole name, and the issuer thereof
shall be entitled to comply with and honor any and all such documents or
instruments executed by or received solely from Lender, all without any notice
to or any consent from Borrower. None of the foregoing actions described in this
subsection (g) may be taken by Borrower without Lender's express written
consent.

         2.4      Certain Amounts Due Without Demand. Lender may, in its sole
discretion, make or permit Revolving Loans, Accommodations or other Obligations
in excess of the Maximum Credit,


                                       -7-


<PAGE>   8



Gross or Net Availability or applicable formulas or sublimits. All or any
portion of such excess(es) shall be immediately due and payable without Lender's
demand.

SECTION 3.  INTEREST AND FEES

         3.1      Interest. (a) Interest on the Revolving Loans and Term Loans
shall be payable by Borrower on the first day of each month, calculated upon the
closing daily balances in the loan account of Borrower for each day during the
immediately preceding month, at the per annum rate set forth as the Interest
Rate in Section 10.4(a). The Interest Rate shall increase or decrease by an
amount equal to each increase or decrease, respectively, in the Prime Rate (as
defined below), effective as of the date of each such change. On and after any
Event of Default or termination or non-renewal hereof, interest on the unpaid
principal amount of all unpaid Obligations shall accrue at a rate equal to two
percent (2%) per annum in excess of the Interest Rate otherwise payable until
such time as all Obligations are indefeasibly paid in full (notwithstanding
entry of any judgment against Borrower or the exercise of any other right or
remedy by Lender), and all such interest shall be payable on demand. The "PRIME
RATE" is the rate of interest publicly announced by Chemical Bank in New York,
New York, or its successors, and assigns from time to time as its prime rate
(the Prime Rate is not intended to be the lowest rate of interest charged by
Chemical Bank to its borrowers). The Prime Rate on the date hereof is 8.50% and
therefore the rate of interest in effect under this Agreement on the date
hereof, expressed in simple interest terms, is 10.125% per annum.

         (b)      If the amount of interest to be paid in any month based upon
the outstanding principal amount of the Obligations during the immediately
preceding month is less than the Minimum Interest Amount, then, subject to the
provisions of Section 3.8 hereof, Borrower shall be obligated to pay the Minimum
Interest Amount on the date that accrued interest is due and payable for such
immediately preceding month. As used herein, the term "MINIMUM INTEREST AMOUNT"
shall mean the interest amount that would have been paid for such month if the
average principal amount of Obligations outstanding during such month was at
least equal to the Base Loan Amount for such month. As used herein, the term
"BASE LOAN AMOUNT" shall mean, for any month, an amount equal to $30,000,000 if
such month is in the first Loan Year (as defined in Section 9.2), $15,000,000 if
such month is in the second Loan Year, and $10,000,000 if such month is in the
third or any subsequent Loan Year.

         3.2      Annual Commitment Fee. Borrower shall pay Lender on each
anniversary of the "CLOSING DATE" (as defined in the Conditions Precedent Rider)
an Annual Commitment Fee in the amount set forth in Section 10.4(b), which fee
shall be fully earned as of each such anniversary date.

         3.3      Closing Fee. Borrower shall pay Lender on the Closing Date a
closing fee in the amount set forth in Section 10.4(c), which fee shall be
deemed fully earned as of the Closing Date and shall be non-refundable except to
the extent otherwise required by applicable law.



                                       -8-


<PAGE>   9



         3.4      Account Servicing Fee. Borrower shall pay Lender monthly, on
the first day of each month during the initial and each renewal Term an Account
Servicing Fee for the immediately preceding month (or part thereof) in the
amount set forth in Section 10.4(d).

         3.5      Unused Line Fee. Borrower shall pay Lender monthly, on the
first day of each month, in arrears, an Unused Line Fee for each month during
the initial and each renewal Term at the rate per annum set forth in Section
10.4(e), calculated upon the amount, if any, by which the Maximum Credit exceeds
the average outstanding daily principal balance during the preceding month of
all Revolving Loans, Accommodations and Term Loans.

         3.6      Charges to Loan Account. At Lender's option, all payments of
principal, interest, fees, costs, expenses and other charges provided for in
this Agreement, or in any other agreement now or hereafter existing between
Lender and Borrower, may be charged on the date when due, as principal to any
loan account of Borrower maintained by Lender.

         3.7      Calculation of Interest and Fees. Interest, fees for
Accommodations, the Unused Line Fee and any other amounts payable by Borrower to
Lender based on a per annum rate shall be calculated on the basis of actual days
elapsed over a 360-day year.

         3.8      Maximum Interest Charges. Regardless of any provision
contained in this Agreement, any of the other "TRANSACTION DOCUMENTS" (as
defined in the Conditions Precedent Rider), or any other instrument or agreement
now or hereafter evidencing or securing the payment of any of the Obligations,
in no contingency or event whatsoever shall the aggregate of all amounts that
are contracted for, charged or collected pursuant to the terms of this
Agreement, or any other agreement, that are deemed interest under applicable law
exceed the highest rate permissible under any applicable law. No agreements,
conditions, provisions or stipulations contained in this Agreement or the
exercise by Lender of the right to accelerate the payment or the maturity of all
or any portion of the Obligations, or the exercise of any option whatsoever
contained in this Agreement, or the prepayment by Borrowers of any of the
Obligations, or the occurrence of any contingency whatsoever, shall entitle
Lender to charge or receive in any event, interest or any charges, premiums,
fees or other amounts deemed interest by applicable law in excess of the maximum
rate authorized by applicable law and in no event shall Borrower be obligated to
pay interest exceeding such maximum rate, and all agreements, conditions or
stipulations, if any, which may in any event or contingency whatsoever operate
to bind, obligate or compel Borrower to pay interest exceeding the maximum rate
shall be without binding force or effect, at law or in equity, to the extent
only of the excess of interest over such maximum rate. If any interest is
charged or received in excess of the maximum rate, Borrower acknowledges and
agrees that such charge or receipt shall be the result of an accident and bona
fide error, in such excess, to the extent received, shall be applied first to
reduce the principal amount of the Obligations and the balance, if any, returned
to Borrower, it being the intent of the parties hereto not to enter into a
usurious or otherwise illegal relationship. The right to accelerate the maturity
of any of the Obligations does not include the right to accelerate any interest
that is not otherwise accrued on the date of such acceleration, and Lender does
not intend


                                       -9-


<PAGE>   10



to collect any unearned interest in the event of any such acceleration. For the
purpose of determining whether or not any excess of interest has been contracted
for, charged or received by Lender, all interest at any time contracted for,
charged or received from Borrower in connection with any of the Obligations
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated and spread in equal parts throughout the full term of the Obligations.

SECTION 4.  GRANT OF SECURITY INTEREST

         4.1      Grant of Security Interest. To secure the payment and
performance in full of all Obligations, Borrower hereby grants to Lender a
continuing security interest in and lien upon, and a right of setoff against,
and Borrower hereby assigns and pledges to Lender, all of the Collateral,
including, without limitation, any Collateral not deemed eligible for lending
purposes.

         4.2      The term "OBLIGATIONS" shall mean any and all Revolving Loans,
Term Loans, Accommodations and all other indebtedness, liabilities and
obligations of every kind, nature and description owing by Borrower to Lender
and/or its affiliates, including, without limitation, principal, interest,
charges, fees and expenses, however evidenced, whether as principal, surety,
endorser, guarantor or otherwise, whether arising under this Agreement or
otherwise, whether now existing or hereafter arising, whether arising before,
during or after the initial or any renewal Term or after the commencement of any
case with respect to Borrower under the United States Bankruptcy Code or any
similar statute, whether direct or indirect, absolute or contingent, joint or
several, due or not due, primary or secondary, liquidated or unliquidated,
secured or unsecured, original, renewed or extended and whether arising directly
or howsoever acquired by Lender including, without limitation, from any other
entity outright, conditionally or as collateral security, by assignment, merger
with any other entity, participations or interests of Lender in the obligations
of Borrower to others, assumption, operation of law, subrogation or otherwise
and shall also include all amounts chargeable to Borrower under this Agreement
or in connection with any of the foregoing.

         4.3      "COLLATERAL" shall mean all of the following property of
Borrower:

         All now owned and hereafter acquired right, title and interest of
Borrower in, to and in respect of all: accounts, interests in goods represented
by accounts, returned, reclaimed or repossessed goods with respect thereto and
rights as an unpaid vendor; contract rights; chattel paper; general intangibles,
including, but not limited to, tax and duty refunds, registered and unregistered

licensee), choses in action and other claims, and existing and future leasehold
interests in equipment and fixtures; documents; instruments; letters of credit,
bankers' acceptances or guaranties; cash monies, deposits, securities,

time, participates in Lender's financing of Borrower or at any other depository
or other institution; agreements or property securing or relating to any of the
items referred to above;

         All now owned and hereafter acquired right, title and interest of
Borrower in, to and in respect of goods, including, but not limited to:

         without limitation, all raw materials, work-in-process, finished goods,
         and materials to be used or consumed in Borrower's business; and all
         names or marks affixed to or to be affixed thereto for purposes of
         selling same by the seller, manufacturer, lessor or licensor thereof;

                  All equipment and fixtures, wherever located, whether now

                  All consumer goods, farm products, crops, timber, minerals or

         located, whether now owned or hereafter acquired, of whatever kind,

         of or damage to any of the foregoing.

SECTION 5.   COLLECTION AND ADMINISTRATION

         5.1      Collections. Borrower shall, at Borrower's expense and in the
manner requested by Lender from time to time, direct that remittances and all
other proceeds of accounts and other Collateral shall be sent to a lock box
designated by and/or maintained in the name of Lender, and deposited into a bank
account now or hereafter selected by Lender and maintained in the name of Lender
under arrangements with the depository bank under which all funds deposited to
such bank account are required to be transferred solely to Lender. Borrower
shall bear all risk of loss of any


                                      -11-


<PAGE>   12



funds deposited into such account. In connection therewith, Borrower shall
execute such lock box and bank account agreements as Lender shall specify. Any
collections or other proceeds received by Borrower shall be held in trust for
Lender and immediately remitted to Lender in kind.

         5.2      Payments. All Obligations shall be payable at Lender's office
set forth below or at Lender's bank designated in Section 10.6(a) or at such
other bank or place as Lender may expressly designate from time to time for
purposes of this Section. Lender shall apply all proceeds of accounts or other
Collateral received by Lender and all other payments in respect of the
Obligations to the Revolving Loans whether or not then due or to any other
Obligations then due, in whatever order or manner Lender shall determine. For
purposes of determining Gross and Net Availability, remittances and other
payments with respect to the Collateral and Obligations will be treated as
credited to the loan account of Borrower maintained by Lender and Collateral
balances to which they relate, upon the date of Lender's receipt of advice from
Lender's bank that such remittances or other payments have been credited to
Lender's account or in the case of remittances or other payments received
directly in kind by Lender, upon the date of Lender's deposit thereof at
Lender's bank, subject to final payment and collection. In computing interest
charges, the loan account of Borrower maintained by Lender will be credited with
remittances and other payments two (2) Business Days after the day Lender has
received advice of receipt of remittances in Lender's account at Lender's Bank.
For purposes of this Agreement, "BUSINESS DAY" shall mean any day other than a
Saturday, Sunday or any other day on which banks located in the State of New
York are authorized to close.

         5.3      Loan Account Statements. Lender shall render to Borrower
monthly a loan account statement. Each statement shall be considered correct and
binding upon Borrower as an account stated, except to the extent that Lender
receives, within sixty (60) days after the mailing of such statement, written
notice from Borrower of any specific exceptions by Borrower to that statement.

         5.4      Direct Collections. Lender may, at any time, whether or not an
Event of Default has occurred, without notice to or assent of Borrower, (a)
notify any account debtor that the accounts and other Collateral which includes
a monetary obligation have been assigned to Lender by Borrower and that payment
thereof is to be made to the order of and directly to Lender, (b) send, or cause
to be sent by its designee, requests (which may identify the sender by a
pseudonym) for verification of accounts and other Collateral directly to any
account debtor or any other obligor or any bailee with respect thereto, and (c)
demand, collect or enforce payment of any accounts or such other Collateral, but
without any duty to do so, and Lender shall not be liable for any failure to
collect or enforce payment thereof. At Lender's request, all invoices and
statements sent to any account debtor, other obligor or bailee, shall state that
the accounts and such other Collateral have been assigned to Lender and are
payable directly and only to Lender.

         5.5      Attorney-in-Fact. Borrower hereby appoints Lender and any
designee of Lender as Borrower's attorney-in-fact and authorizes Lender or such
designee, at Borrower's sole expense, to exercise at any times in Lender's or
such designee's discretion all or any of the following powers, which powers of
attorney, being coupled with an interest, shall be irrevocable until all
Obligations


                                      -12-


<PAGE>   13



have been paid in full: (a) receive, take, endorse, assign, deliver, accept and
deposit, in the name of Lender or Borrower, any and all cash, checks, commercial
paper, drafts, remittances and other instruments and documents relating to the
Collateral or the proceeds thereof, (b) transmit to account debtors, other
obligors or any bailees notice of the interest of Lender in the Collateral or
request from account debtors or such other obligors or bailees at any time, in
the name of Borrower or Lender or any designee of Lender, information concerning
the Collateral and any amounts owing with respect thereto, (c) notify account
debtors or other obligors to make payment directly to Lender, or notify bailees
as to the disposition of Collateral, (d) after an Event of Default, take or
bring, in the name of Lender or Borrower, all steps, actions, suits or
proceedings deemed by Lender necessary or desirable to effect collection of or
other realization upon the accounts and other Collateral, (e) after an Event of
Default, change the address for delivery of mail to Borrower and to receive and
open mail addressed to Borrower, (f) after an Event of Default, extend the time
of payment of, compromise or settle for cash, credit, return of merchandise, and
upon any terms or conditions, any and all accounts or other Collateral which
includes a monetary obligation and discharge or release the account debtor or
other obligor, without affecting any of the Obligations, and (g) execute in the
name of Borrower and file against Borrower in favor of Lender financing
statements or amendments with respect to the Collateral.

         5.6      Limitation on Liability. Borrower hereby releases and
exculpates Lender, its officers, employees and designees, from any liability
arising from any acts under this Agreement or in furtherance thereof, whether as
attorney-in-fact or otherwise, whether of omission or commission, and whether
based upon any error of judgment or mistake of law or fact, except for gross
negligence or willful misconduct. In no event will Lender have any liability to
Borrower for lost profits or other special or consequential damages.

         5.7      Administration of Accounts. After the occurrence of an Event
of Default, Borrower shall not (a) grant any extension of time of payment of any
of the accounts or any other Collateral which includes a monetary obligation,
(b) compromise or settle any of the accounts or any such other Collateral for
less than the full amount thereof, (c) release in whole or in part any account
debtor or other person liable for the payment of any of the accounts or any such
other Collateral, or (d) grant any credits, discounts, allowances, deductions,
return authorizations or the like with respect to any of the accounts or any
such other Collateral. Prior to the occurrence of an Event of Default, Borrower
may take any of the foregoing actions in the ordinary course of its business as
presently conducted, unless Lender has in writing directed Borrower not to do so
in a specific instance.

         5.8      Documents. At such times as Lender may request and in the
manner specified by Lender, Borrower shall deliver to Lender or Lender's
representative, as Lender shall designate, copies or original invoices,
agreements, proofs of rendition of services and delivery of goods and other
documents evidencing or relating to the transactions which gave rise to accounts
or other Collateral, together with customer statements, schedules describing the
accounts or other Collateral and/or statements of account and confirmatory
assignments to Lender of the accounts or other Collateral, in form and substance
satisfactory to Lender and duly executed by Borrower. Without


                                      -13-


<PAGE>   14



limiting the provisions of Section 5.7, Borrower's granting of credits,
discounts, chargebacks, allowances, deductions, return authorizations or the
like will be promptly reported to Lender in writing. In no event shall any such
schedule or confirmatory assignment (or the absence thereof or omission of any
of the accounts or other Collateral therefrom) limit or in any way be construed
as a waiver, limitation or modification of the security interests or rights of
Lender or the warranties, representations and covenants of Borrower under this
Agreement. Any documents, schedules, invoices or other paper delivered to Lender
by Borrower may be destroyed or otherwise disposed of by Lender six (6) months
after receipt by Lender, unless Borrower requests their return in writing in
advance and makes prior arrangements for their return at Borrower's expense.

         5.9      Access. From time to time as requested by Lender, at the sole
expense of Borrower, Lender or its designee shall have access, prior to an Event
of Default during reasonable business hours and on or after an Event of Default
at any time, to all of the premises where Collateral is located for the purposes
of inspecting the Collateral, and all Borrower's books and records, and Borrower
shall permit Lender or its designee to make such copies of such books and
records or extracts therefrom as Lender may request. Without expense to Lender,
Lender may use such of Borrower's personnel, equipment, including, without
limitation, computer equipment, programs, printed output and computer readable
media, supplies and premises for the collection of accounts and realization on
other Collateral as Lender, in its sole discretion, deems appropriate. Borrower
hereby irrevocably authorizes all accountants and third parties to disclose and
deliver to Lender at Borrower's expense all financial information, books and
records, work papers, management reports and other information in their
possession regarding Borrower (except that the foregoing shall not be deemed to
waive any applicable attorney-client privilege).

         5.10     Environmental Audits. From time to time, as requested by
Lender, at the sole expense of Borrower, Borrower shall provide Lender, or its
designee, complete access to all of Borrower's facilities for the purpose of
conducting an environmental audit of such facilities as Lender or its designees
may deem necessary. Borrower agrees to cooperate with Lender with respect to any
environmental audit conducted by Lender or its designee pursuant to this Section
5.10.

SECTION 6.        ADDITIONAL REPRESENTATIONS, WARRANTIES AND COVENANTS

         Borrower hereby represents, warrants and covenants to Lender the
following, the truth and accuracy of which, and compliance with which, shall be
continuing conditions of the making of loans or other credit accommodations by
Lender to Borrower:

         6.1      Financial and Other Reports. Borrower shall keep and maintain
its books and records in accordance with generally accepted accounting
principles, consistently applied. Borrower shall, at its expenses deliver to
Lender: (a) true and complete monthly agings of its accounts receivable,
accounts payable and notes payable; (b) weekly inventory reports; (c) monthly
internally prepared interim financial statements. Annually, Borrower shall
deliver audited financial statements of Borrower accompanied by the report and
opinion thereon of independent certified public accountants acceptable to
Lender, as soon as available, but in no event later than ninety (90) days after
the end of Borrower's fiscal year. Except for audited financial statements
prepared in accordance with generally accepted accounting principles, all of the
foregoing shall be in such form and together with such information with respect
to the business of Borrower or any Guarantor, as Lender may in each case
request.

         6.2      Trade Names. Borrower may from time to time render invoices to
account debtors under any trade names set forth in Section 10.6(e) after Lender
has received prior written notice from Borrower of the use of such trade names
and as to which, Borrower agrees that: (a) each trade name does not refer to
another corporation or other legal entity, (b) all accounts and proceeds thereof
(including, without limitation, any returned merchandise) invoiced under any
such trade names are owned exclusively by Borrower and are subject to the
security interest of Lender and the other terms of this Agreement, and (c) all
schedules of accounts and confirmatory assignments including, without
limitation, any sales made or services rendered using the trade name shall show
Borrower's name as assignor and Lender is authorized to receive, endorse and
deposit to any loan account of Borrower maintained by Lender all checks or other
remittances made payable to any trade name of Borrower representing payment with
respect to such sales or services.

         6.3      Losses. Borrower shall promptly notify Lender in writing of
any loss, damage, investigation, action, suit, proceeding or claim relating to a
material portion of the Collateral or which may result in any material adverse
change in Borrower's business, assets, liabilities or condition, financial or
otherwise.

         6.4      Books and Records. Borrower's books and records concerning
accounts and its chief executive office are and shall be maintained only at the
address set forth in Section 10.6(d). Borrower's only other places of business
and the only other locations of Collateral, if any, are and shall be the
addresses set forth in Section 10.6(b) hereof, except Borrower may change such
locations or open a new place of business after thirty (30) days prior written
notice to Lender. Prior to any change in location or opening of any new place of
business, Borrower shall execute and


                                      -15-


<PAGE>   16



deliver or cause to be executed and delivered to Lender such financing
statements, financing documents and security and other agreements as Lender may
reasonably require, including, without limitation, those described in Section
6.14.

         6.5      Title and Liens. Borrower has and at all times will continue
to have good and marketable title to all of the Collateral, free and clear of
all liens, security interests, claims or encumbrances of any kind except in
favor of Lender and except for Permitted Liens.

         6.6      Asset Dispositions; Fundamental Changes. Borrower shall not
directly or indirectly: (a) sell, lease, transfer, assign, abandon or otherwise
dispose of any part of the Collateral (other than sales of inventory to buyers
in the ordinary course of business) or any material portion of its other assets
(other than the sale of its real estate in the 7th District, Gwinnett County,
Georgia, to the extent approved by the Court (as defined in the Condition
Precedent Rider)) or (b) consolidate with or merge with or into any other
entity, or permit any other entity to consolidate with or merge with or into
Borrower except as provided in the "MERGER AGREEMENT" (as defined in the
Condition Precedent Rider) or (c) form or acquire any interest in any firm,
corporation or other entity (other than a majority owned subsidiary in which
Borrower invests no more than $100,000 and which is engaged in substantially the
same business as is engaged in on the date hereof by Borrower or Borrower's
existing subsidiaries).

         6.7      Insurance. Borrower shall at all times maintain, with
financially sound and reputable insurers, insurance (including, without
limitation, at the option of Lender, earthquake insurance if and to the extent
available at commercially reasonable rates) with respect to the Collateral and
other assets. All such insurance policies shall be in such form, substance,
amounts and coverage as may be satisfactory to Lender and shall provide for
thirty (30) days' prior written notice to Lender of cancellation or reduction of
coverage. Borrower hereby irrevocably appoints Lender and any designee of Lender
as attorney-in-fact for Borrower to obtain at Borrower's expense, any such
insurance should Borrower fail to do so and, after an Event of Default, to
adjust or settle any claim or other matter under or arising pursuant to such
insurance or to amend or cancel such insurance. Borrower shall deliver to Lender
evidence of such insurance and a lender's loss payable endorsement satisfactory
to Lender as to all existing and future insurance policies with respect to the
Collateral. Borrower shall deliver to Lender, in kind, all instruments
representing proceeds of insurance received by Borrower. Lender may apply any
insurance proceeds received at any time to the cost of repairs to or replacement
of any portion of the Collateral and/or, at Lender's option, to payment of or as
security for any of the Obligations, whether or not due, in any order or manner
as Lender determines. Borrower shall also maintain in full force and effect (i)

         6.8      Compliance With Laws. Borrower is and at all times will
continue to be in compliance with the requirements of all applicable laws,

business (including, without limitation, laws, rules, regulations and orders
relating to taxes, payment and withholding of payroll taxes, employer and
employee contributions and similar items, securities, employee retirement and
welfare benefits, employee health and safety, or environmental matters) to the
extent that noncompliance therewith might reasonably be expected to have a
Material Adverse Effect, and is and will remain in compliance with all material
agreements or other instruments binding on Borrower or its property to the

1938, as amended and all rules, regulations and orders related thereto. Borrower
shall pay and discharge all taxes, assessments and governmental charges against
Borrower or any Collateral prior to the date on which penalties are imposed or
liens attach with respect thereto, unless the same are being actively contested
in good faith any by appropriate proceedings, no lien results therefrom that is
not a Permitted Lien, Borrower has established appropriate reserves therefor in
accordance with generally accepted accounting principles, and, at Lender's
option, Reserves are established for the amount contested and penalties which
may accrue thereon to the extent reasonably determined by Lender to be necessary
to insure that Borrower has sufficient Net Availability to pay such contested
items in the event of a resolution thereof requiring payment in whole or in part
of any such items.

         6.9      Accounts. With respect to each account deemed an Eligible

except as disclosed in writing to Lender at the time such account arises (a)
each is valid and legally enforceable and represents an undisputed bona fide
indebtedness incurred by the account debtor for the sum reported to Lender, (b)
each arises from an absolute and unconditional sale of goods, without any right
of return or consignment (except in the ordinary course of Borrower's business
as presently conducted in connection with warranty returns and stock adjustments
and price protection programs offered by Borrower to its customers), or from a
completed rendition of services, (c) each is not, at the time such account
arises, subject to any defense, offset, dispute, contra relationship,
counterclaim, or any given or claimed credit, allowance or discount, and (d) all
statements made and all unpaid balances and other information appearing in the
invoices, agreements, proofs of rendition of services and delivery of goods and
other documentation relating to the accounts, and all confirmatory assignments,
schedules, statements of account and books and records with respect thereto, are
true and correct and in all material respects what they purport to be.

shall keep the equipment in good order and repair, and in running and marketable
condition, ordinary wear and tear excepted.

                                      -22-


<PAGE>   23



discretion, alternatively, successively, or concurrently on any one or more
occasions and in any order Lender may determine. Without limiting the foregoing,
Lender may (a) accelerate the payment of all Obligations and demand immediate
payment thereof to Lender, (b) with or without judicial process or the aid or
assistance of others, enter upon any premises on or in which any of the
Collateral may be located and take possession of the Collateral or complete
processing, manufacturing and repair of all or any portion of the Collateral,
(c) require Borrower, at Borrower's expense, to assemble and make available to
Lender any part or all of the Collateral at any place and time designated by
Lender, (d) collect, foreclose, receive, appropriate, setoff and realize upon
any and all Collateral, (e) extend the time of payment of, compromise or settle
for cash, credit, return of merchandise, and upon any terms or conditions, any
and all accounts or other Collateral which includes a monetary obligation and

dispose of any and all Collateral (including, without limitation, entering into
contracts with respect thereto, by public or private sales at any exchange,
broker's board, any office of Lender or elsewhere) at such prices or terms as
Lender may deem reasonable, for cash, upon credit or for future delivery, with
the Lender having the right to purchase the whole or any part of the Collateral
at any such public sale, all of the foregoing being free from any right or
equity of redemption of Borrower, which right or equity of redemption is hereby
expressly waived and released by Borrower. If any of the Collateral is sold or
leased by Lender upon credit terms or for future delivery, the Obligations shall
not be reduced as a result thereof until payment therefor is finally collected
by Lender. If notice of disposition of Collateral is required by law, seven (7)
days prior notice by Lender to Borrower designating the time and place of any
public sale or the time after which any private sale or other intended
disposition of Collateral is to be made, shall be deemed to be reasonable notice
thereof and Borrower waives any other notice. In the event Lender institutes an
action to recover any Collateral or seeks recovery of any Collateral by way of
prejudgment remedy, Borrower waives the posting of any bond which might
otherwise be required.

         7.3      Application of Proceeds. Lender may apply the cash proceeds of
Collateral actually received by Lender from any sale, lease, foreclosure or
other disposition of the Collateral to payment of any of the Obligations, in
whole or in part (including, without limitation, reasonable attorneys' fees and
legal expenses incurred by Lender with respect thereto or otherwise chargeable
to Borrower) and in such order as Lender may elect, whether or not then due.
Borrower shall remain liable to Lender for the payment of any deficiency
together with interest at the highest rate provided for herein and all costs and
expenses of collection or enforcement, including, without limitation, reasonable
attorneys' fees and legal expenses.

         7.4      Lender's Cure of Third Party Agreement Default. Lender may, at
its option, cure any default by Borrower under any agreement with a third party
or pay or bond on appeal any judgment entered against Borrower, discharge taxes,
liens, security interests or other encumbrances at any time levied on or
existing with respect to the Collateral and pay any amount, incur any expense or
perform any act which, in Lender's sole judgment, is necessary or appropriate to
preserve, protect, insure, maintain, or realize upon the Collateral. Lender may
charge Borrower's loan account for any


                                      -23-


<PAGE>   24



amounts so expended, such amounts to be repayable by Borrower on demand. Lender
shall be under no obligation to effect such cure, payment, bonding or discharge,
and shall not, by doing so, be deemed to have assumed any obligation or
liability of Borrower.

SECTION 8.        JURY TRIAL WAIVER; CERTAIN OTHER WAIVERS AND CONSENTS

         8.1      JURY TRIAL WAIVER. BORROWER AND LENDER EACH WAIVE ALL RIGHTS

AGAINST THE OTHER WHICH PERTAINS DIRECTLY OR INDIRECTLY TO THIS AGREEMENT, THE
OBLIGATIONS, THE COLLATERAL, ANY ALLEGED TORTUOUS CONDUCT BY BORROWER OR LENDER,
OR, IN ANY WAY, DIRECTLY OR INDIRECTLY, ARISES OUT OF OR RELATES TO THE
RELATIONSHIP BETWEEN BORROWER AND LENDER. IN NO EVENT WILL LENDER BE LIABLE FOR
LOST PROFITS OR OTHER SPECIAL OR CONSEQUENTIAL DAMAGES.

         8.2      Counterclaims. Borrower waives all rights to interpose any
claims, deductions, setoffs or counterclaims of any kind, nature or description
in any action or proceeding instituted by Lender with respect to this Agreement,
the Obligations, the Collateral or any matter arising therefrom or relating
thereto, except compulsory counterclaims.

         8.3      Jurisdiction. Borrower hereby irrevocably submits and consents
to the nonexclusive jurisdiction of the State and Federal Courts located in the
State in which the office of Lender designated in Section 10.6(a) is located and
any other State where any Collateral is located with respect to any action or
proceeding arising out of this Agreement, the Obligations, the Collateral or any
matter arising therefrom or relating thereto. In any such action or proceeding,
Borrower waives personal service of the summons and complaint or other process
and papers therein and agrees that the service thereof may be made by mail
directed to Borrower at its chief executive office set forth herein or other
address thereof of which Lender has received notice as provided herein, service
to be deemed complete five (5) days after mailing, or as permitted under the
rules of either of said Courts. Any such action or proceeding commenced by
Borrower against Lender will be litigated only in a Federal Court located in the
district, or a State Court in the State and County, in which the office of
Lender designated in Section 10.6(a) is located and Borrower waives any
objection based on FORUM NON CONVENIENS and any objection to venue in connection
therewith.

         8.4      No Waiver by Lender. Lender shall not, by any act, delay,
omission or otherwise be deemed to have expressly or impliedly waived any of its
rights or remedies unless such waiver shall be in writing and signed by an
authorized officer of Lender. A waiver by Lender of any right or remedy on any
one occasion shall not be construed as a bar to or waiver of any such right or
remedy which Lender would otherwise have on any future occasion, whether similar
in kind or otherwise.

SECTION 9.        TERM OF AGREEMENT; MISCELLANEOUS


         9.1      Term. This Agreement shall only become effective upon
execution and delivery by Borrower and Lender in Atlanta, Georgia, and shall
continue in full force and effect for a term of three (3) years from the Closing
Date hereof and shall be deemed automatically renewed for successive terms of
three (3) years thereafter unless terminated as of the end of the initial or any
renewal term (each a "TERM") by either party giving the other written notice at
least sixty (60) days' prior to the end of the then-current Term.

         9.2      Early Termination. Borrower may terminate this Agreement by
giving Lender at least thirty (30) days prior written notice at any time upon
payment in full of all of the Obligations as provided herein, including, without
limitation, the early termination fee provided below. Lender shall have the
right to terminate this Agreement (i) at any time upon or after the occurrence
of an Event of Default or (ii) upon ninety (90) days' prior written notice to
Borrower if (A) there shall occur any change in the controlling ownership of
Borrower (other than a change of ownership contemplated by the Merger Documents)
or any person now or hereafter occupying the position of Borrower's chief
executive officer, chief financial officer or chief operating officer shall
cease for any reason to occupy such position, and (B) Northern Telecom Inc. does
not own at the time in question at least 20.2% of the outstanding equity
securities in Borrower. If Lender or Borrower shall terminate this Agreement
effective as of any date other than the last day of the then current Term,
Borrower shall pay to Lender (in addition to all other Obligations) upon the
effective date of such termination, in view of the impracticality and extreme
difficulty of ascertaining actual damages and by mutual agreement of the parties
as to a reasonable calculation of Lender's lost profits, an early termination
fee calculated as follows:

                  that, unless and until Lender sells an additional
                  participation to a new participant satisfactory in all
                  respects to Lender in a maximum amount of $5,500,000, the
                  principal amount of the Obligations outstanding at any time

                  whatsoever to solicit the purchase of any such participation
                  and shall have no liability to Borrower for any failure to
                  procure or delay in procuring a participant to replace Key
                  Bank.

                     FOURTH AMENDMENT TO LOAN AND SECURITY
                        AGREEMENT AND CONSENT AGREEMENT

         THIS FOURTH AMENDMENT TO LOAN AND SECURITY AGREEMENT AND CONSENT
AGREEMENT (this "Agreement") is made and entered into as of the 30th day of
December, 1997, by and between HAYES MICROCOMPUTER PRODUCTS, INC., a Georgia
corporation (hereinafter referred to as "Borrower") with its chief executive
office and principal place of business at 5854 Peachtree Corners East,
Norcross, Georgia 30072, and THE CIT GROUP/CREDIT FINANCE, INC., a Delaware
corporation (hereinafter referred to as "Lender") with an office at 1211 Avenue
of the Americas, 21st Floor, New York, New York 10036.

                                   RECITALS:

         Lender and Borrower are parties to a certain Loan and Security
Agreement and a certain Condition Precedent Rider thereto, both dated December
21, 1995, as amended by that certain First Amendment to Loan and Security
Agreement April 16, 1996, that certain Second Amendment to Loan and Security
Agreement dated October 15, 1996, and that certain Third Amendment to Loan and
Security Agreement dated as of January 1, 1997 (collectively, as at any time
amended, the "Loan Agreement"), pursuant to which Lender has made certain
revolving credit and term loans to Borrower.

         The parties desire to amend the Loan Agreement as hereinafter set
forth.

         NOW, THEREFORE, for TEN DOLLARS ($10.00) in hand paid and other good
and valuable consideration, the receipt and sufficiency of which are hereby
severally acknowledged, the parties hereto, intending to be legally bound
hereby, agree as follows:

                  1.       DEFINITIONS.  All capitalized terms used in this
Agreement, unless otherwise defined herein, shall have the meaning
ascribed to such terms in the Loan Agreement.

                  2.       AMENDMENT TO LOAN AGREEMENT.  The Loan Agreement is
hereby amended as follows:

                           a.  By deleting Section 3.1(b) in its entirety and
by substituting the following new Section 3.1(b) in lieu thereof:

                  (b)      If the amount of interest to be paid in any month
         based upon the outstanding principal amount of the Obligations during
         the immediately preceding month is less than the Minimum Interest
         Amount, then, subject to






<PAGE>   2



         the provisions of Section 3.8 hereof, Borrower shall be obligated to
         pay the Minimum Interest Amount on the date that accrued interest is
         due and payable for such immediately preceding month. As used herein,
         the term "MINIMUM INTEREST AMOUNT" shall mean the interest amount that
         would have been paid for such month if the average principal amount of
         Obligations outstanding during such month was at least equal to the
         Base Loan Amount for such month. As used herein, the term "BASE LOAN
         AMOUNT" shall mean, for any month, an amount equal to $10,000,000.

                           b.       By deleting Section 9.1 in its entirety and
by substituting the following new Section 9.1 in lieu thereof:

                  9.1      Term. This Agreement shall only become effective
         upon execution and delivery by Borrower and Lender in Atlanta,
         Georgia, and shall continue in full force and effect for a term of
         five (5) years from the Closing Date hereof and shall be deemed
         automatically renewed for successive terms of three (3) years
         thereafter unless terminated as of the end of the initial or any
         renewal term (each a "TERM") by either party giving the other written
         notice at least sixty (60) days' prior to the end of the then-current
         Term.

                           c.       By deleting Section 9.2 in its entirety and
by substituting the following new Section 9.2 in lieu thereof:

                  9.2      Early Termination. Borrower may terminate this
         Agreement by giving Lender at least thirty (30) days prior written
         notice at any time upon payment in full of all of the Obligations as
         provided herein, including, without limitation, the early termination
         fee provided below. Lender shall have the right to terminate this
         Agreement (i) at any time upon or after the occurrence of an Event of
         Default or (ii) upon ninety (90) days' prior written notice to
         Borrower if (A) there shall occur any change in the controlling
         ownership of Borrower (other than a change of ownership contemplated
         by the Merger Documents) or any person now or hereafter occupying the
         position of Borrower's chief executive officer, chief financial
         officer or chief operating officer shall cease for any reason to
         occupy such position, and (B) Hayes Corporation, a Delaware
         corporation, does not own at the time in question at least 90% of the
         outstanding equity securities in Borrower. If Lender or Borrower shall
         terminate this Agreement effective as of any date other than the last
         day of the then current Term, Borrower shall pay to Lender (in
         addition to all other Obligations) upon the effective date of such
         termination, in view of the impracticality and extreme difficulty of



                                       2

         ascertaining actual damages and by mutual agreement of the parties as
         to a reasonable calculation of Lender's lost profits, an early
         termination fee calculated as follows:

<TABLE>

         (a)   on or before April    (a)  $450,000
               16, 1998

         (b)   from April 17, 1998,  (b)  1% of the greater of the Base

                                          which notice of termination 
                                          is given or the Average Daily
                                          Loan Balance for the 180-day
                                          period prior to the effective
                                          date of termination, plus $150,000
</TABLE>

         If the effective date of termination pursuant to a properly given
         notice occurs on the last day of any Term, then no termination charge
         shall be payable. As used in this Agreement, the term "LOAN YEAR"
         shall mean a period commencing on the Closing Date or an anniversary
         thereof and ending on the next anniversary; and the term "AVERAGE
         DAILY LOAN BALANCE" shall mean, for any period, an amount equal to the
         aggregate principal balance of Revolving Loans, Term Loans and
         Accommodations outstanding at the end of each day during such period
         divided by the number of days in such period.

                           d.       By deleting Section 10.1(a) in its entirety

                  (a)      Interest Rate:

                           A fluctuating rate per annum equal to the Prime Rate
                           plus the Applicable Interest Margin. The "APPLICABLE
                           INTEREST MARGIN" shall be 2.125%, until January 1,
                           1998, at which time the Applicable Interest Margin
                           shall be 1.875%; provided, however, that (1) if

                           Borrower has Net Income for its fiscal year ending

("Saliendra") and S.P. Quek Investments, a private Singapore corporation ("S.P.
Quek") (Rinzai, Kaifa, Rolling Profit, LAO, Saliendra and S.P. Quek are
hereinafter referred to collectively as the "Creditors").

         Lender hereby consents to Borrower's use of $11,375,000 of the
proceeds received from the Capital Contribution to satisfy the aggregate of all
indebtedness owing from Borrower to the Creditors (the "Creditor Payoff") and
agrees that the Creditor Payoff will not constitute an Event of Default under
the Loan Agreement or a default under any subordination agreement between
Lender, Borrower and any Creditor, provided, that each of the conditions
precedent set forth in Paragraph 8 hereof are satisfied prior to the Creditor
Payoff, and, provided, that Borrower shall have remitted to Lender an amount
sufficient to satisfy all Obligations owing by Borrower to Lender under Term
Loan B.

                  5.       RATIFICATION AND REAFFIRMATION. Borrower hereby

                               (HAYES CORPORATION)

            Re:   Hayes Microcomputer Products, Inc., a Georgia corporation
                  ("Borrower")


Gentlemen:

         Reference is made to the financing arrangements between The CIT
Group/Credit Finance, Inc. ("Lender") and Borrower pursuant to which Lender may
extend loans, advances and other financial accommodations to Borrower as set
forth in the Loan and Security Agreement between Borrower and Lender dated
December 21, 1995, as supplemented by that certain Conditions Precedent Rider
dated December 21, 1995 between Lender and Borrower, and as amended by that
certain First Amendment to Loan and Security Agreement dated April 16, 1996
between Lender and Borrower, that certain Second Amendment to Loan and Security
Agreement dated October 15, 1996 between Lender and Borrower, that certain Third
Amendment to Loan and Security Agreement dated as of January 1, 1997, and that
certain Fourth Amendment to Loan and Security Agreement dated on or about the
date hereof, between Lender and Borrower and various other agreements, documents
and instruments now or at any time executed or delivered in connection therewith
or otherwise related thereto, including, but not limited to, this Guaranty (all
of the foregoing, as the same now exist or may hereafter be amended, modified,
supplemented, extended, renewed, restated or replaced, being collectively
referred to herein as the "Financing Agreements").

         Due to the close business and financial relationships between Borrower
and the undersigned ("Guarantor"), in consideration of the benefits which will
accrue to Guarantor, and as an inducement for and in consideration of Lender at
any time providing or extending loans, advances and other financial
accommodations to Borrower, whether pursuant to the Financing Agreements or
otherwise, Guarantor hereby, irrevocably and unconditionally, (a) guarantees,
and agrees to be liable for, the prompt indefeasible and full payment and
performance of all revolving loans, term loans, letters of credit, bankers'
acceptances, merchandise purchase guaranties or other guaranties or indemnities
for Borrower's account and all other obligations, liabilities and indebtedness
of every kind, nature or description owing by Borrower to Lender or Lender's
affiliates, including, without limitation, principal, interest, charges, fees
and expenses, however evidenced, whether as principal, surety, endorser,
guarantor or otherwise, whether arising under any of the Financing Agreements or




<PAGE>   2

otherwise, whether now existing or hereafter arising, whether arising before,
during or after the initial or any renewal term of the Financing Agreements or
after the commencement of any case with respect to Borrower under the United
States Bankruptcy Code or any similar statute, whether or not such obligations,
liabilities or indebtedness are direct or indirect, absolute or contingent,
joint or several, due or not due, primary or secondary, liquidated or
unliquidated, secured or unsecured, original, renewed or extended, and whether
arising directly or howsoever acquired by Lender including from any other entity
outright, conditionally or as collateral security, by assignment, merger with
any other entity, participations or interests of Lender in the obligations of
Borrower to others, assumption, operation of law, subrogation or otherwise and
(b) agrees to pay to Lender on demand the amount of all expenses (including,
without limitation, attorneys' fees and legal expenses) incurred by Lender in
connection with the preparation, execution, delivery, recording, administration,
collection, liquidation, enforcement and defense of Borrower's obligations,
liabilities and indebtedness as aforesaid to Lender, Lender's rights in any
collateral or under this Guaranty and all other Financing Agreements or in any
way involving claims by or against Lender directly or indirectly arising out of
or related to the relationship between Borrower and Lender, Guarantor and
Lender, or any other Obligor (as hereinafter defined) and Lender, whether such
expenses are incurred before, during or after the initial or any renewal term of
the Financing Agreements or after the commencement of any case with respect to
Borrower, Guarantor or any other Obligor under the United States Bankruptcy Code
or any similar statute (all of which being collectively referred to herein as
the "Guaranteed Obligations").

         GUARANTOR HEREBY EXPRESSLY WAIVES notice of Lender's acceptance of this
Guaranty, the making of loans, advances and extensions of credit or other
financial accommodations to, and the incurring of any expenses by or in respect
of, Borrower, and presentment, demand, protest, notice of protest, notice of
nonpayment or default and all other notices to which Borrower or Guarantor are
or may be entitled. GUARANTOR ALSO WAIVES notice of, and hereby consents to, (i)
any amendment, modification, supplement, renewal, restatement or extensions of
time of payment of or increase or decrease in the amount of any of the
Guaranteed Obligations or to the Financing Agreements and any collateral, and
the guarantee made herein shall apply to the Guaranteed Obligations as so
amended, modified, supplemented, renewed, restated or extended, increased or
decreased, (ii) the taking, exchange, surrender and releasing of any collateral
or guarantees now or at any time held by or available to Lender for the
obligations of Borrower or any other party at any time liable for or in respect
of the Guaranteed Obligations (individually and collectively, the "Obligors"),
(iii) the exercise of, or refraining from the exercise of any rights against
Borrower, Guarantor or any other Obligor or any collateral, and (iv) the
settlement, compromise or release of, or the waiver of any default with respect
to, any Guaranteed Obligations. Guarantor agrees that the amount of the
Guaranteed Obligations shall not be diminished and the liability of Guarantor
hereunder shall not be otherwise impaired or affected by any of the foregoing.
To the fullest extent permitted by applicable law, GUARANTOR HEREBY FURTHER
WAIVES the right to plead any statute of limitations as a defense to performance
of its obligations under, or to Lender's enforcement of, this Guaranty.

         This Guaranty is a guaranty of payment and not of collection. Guarantor
agrees that Lender need not attempt to collect any Guaranteed Obligations from
Borrower or any other Obligor or to realize upon any collateral (and Guarantor
hereby waives the benefit of any statute or other law that



                                       2
<PAGE>   3

might otherwise require Lender to institute suit against Borrower or any other
Obligor on Guarantor's request or prior to instituting suit against Guarantor),
but Lender may require Guarantor to make immediate payment of the Guaranteed
Obligations to Lender when due or at any time thereafter. Lender may apply any
amounts received in respect of the Guaranteed Obligations to any of the
Guaranteed Obligations, in whole or in part (including reasonable attorneys'
fees and legal expenses incurred by Lender with respect thereto or otherwise
chargeable to Borrower or Guarantor) and in such order as Lender may elect,
whether or not then due.

         No invalidity, irregularity or unenforceability of all or any part of
the Guaranteed Obligations shall affect, impair or be a defense to this
Guaranty, nor shall any other circumstance which might otherwise constitute a
defense available to, or legal or equitable discharge of Borrower in respect of
any of the Guaranteed Obligations or Guarantor in respect of this Guaranty,
affect, impair or be a defense to this Guaranty. Without limitation of the
foregoing, the liability of Guarantor hereunder shall not be discharged or
impaired in any respect by reason of any failure by Lender to perfect or
continue perfection of any lien or security interest in any collateral for the
Guaranteed Obligations or any delay by Lender in perfecting any such lien or
security interest. As to interest, fees and expenses, whether arising before or
after the commencement of any case with respect to Borrower under the United
States Bankruptcy Code or any similar statute, Guarantor shall be liable
therefor, even if Borrower's liability for such amounts does not, or ceases to,
exist by operation of law.

         This Guaranty is absolute, unconditional and continuing and is in
addition to, but not contingent upon Lender's obtaining, any other guaranty of
the whole or any part of the Guaranteed Obligations. Payment by Guarantor shall
be made to Lender at its office from time to time on demand as Guaranteed
Obligations become due. One or more successive or concurrent actions may be
brought hereon against Guarantor either in the same action in which Borrower or
any other Obligors are sued or in separate actions.

         Payment of all amounts now or hereafter owed to Guarantor by Borrower
or any other Obligor is hereby subordinated in right of payment to the
indefeasible payment in full to Lender of the Guaranteed Obligations and is
hereby assigned to Lender as security therefor. Guarantor hereby irrevocably and
unconditionally waives and relinquishes all statutory, contractual, common law,
equitable and all other claims against Borrower, any collateral for the
Guaranteed Obligations or other assets of Borrower or any other Obligor, for
subrogation, reimbursement, exoneration, contribution, indemnification, setoff
or other recourse in respect of sums paid or payable to Lender by Guarantor
hereunder and Guarantor hereby further irrevocably and unconditionally waives
and relinquishes any and all other benefits which Guarantor might otherwise
directly or indirectly receive or be entitled to receive by reason of any
amounts paid by or collected or due from Guarantor, Borrower or any other
Obligor upon the Guaranteed Obligations or realized from their property.

         All sums at any time owed by Lender to Guarantor or to the credit of
Guarantor and any property of Guarantor on which Lender at any time has a lien
or security interest or of which Lender at any time has possession, shall secure
payment and performance of all Guaranteed Obligations and all other obligations
of Guarantor to Lender however arising.



                                       3
<PAGE>   4

         In case proceedings be instituted by or against Borrower or Guarantor
or any other Obligor, in bankruptcy or insolvency, or for reorganization,
arrangement, receivership, or the like, or if Borrower or Guarantor or any other
Obligor calls a meeting of creditors or makes any assignment for the benefit of
creditors, or upon the occurrence of any event which constitutes a default or
event of default under the Financing Agreements, the liability of Guarantor for
the entire Guaranteed Obligations shall mature, even if the liability of
Borrower or any other Obligor therefor does not.

         Guarantor shall continue to be liable hereunder until one of Lender's
officers actually receives a written termination notice by certified mail; but
the giving of such notice shall not relieve Guarantor from liability for any
Guaranteed Obligations incurred before Lender's receipt of such notice of
termination or for post-termination collection expenses and interest pertaining
to any Guaranteed Obligations arising before termination.

         Guarantor agrees that this Guaranty shall remain in full force and
effect or be reinstated, as the case may be, if at any time payment of any of
the Guaranteed Obligations is rescinded or otherwise restored by Lender to
Borrower or to any other person who made such payment, or to the creditors or
creditors' representative of Borrower or such other person.

         Lender's books and records showing the account between Lender and
Borrower shall be admissible in evidence in any action or proceeding as prima
facie proof of the items therein set forth, and any written statements rendered
by Lender to Borrower, to the extent to which no written objection is made
within sixty (60) days after the date thereof, shall be considered correct and
be binding on Guarantor as an account stated for purposes of this Guaranty.

         No delay on Lender's part in exercising any rights hereunder or failure
to exercise the same shall constitute a waiver of such rights. No notice to, or
demand on, Guarantor shall be deemed to be a waiver of the obligation of
Guarantor to take further action without notice or demand as provided herein. No
waiver of any of Lender's rights hereunder, and no modification or amendment of
this Guaranty, shall be deemed to be made by Lender unless the same shall be in
writing, duly signed on Lender's behalf, and each such waiver, if any, shall
apply only with respect to the specific instance involved and shall in no way
impair Lender's rights or the obligations of Guarantor to Lender in any other
respect at any other time.

         Guarantor hereby assumes responsibility for keeping itself informed of
the financial condition of Borrower and any and all endorsers or other
guarantors of any of the Guaranteed Obligations and of all other circumstances
bearing upon the risk of nonpayment of the Guaranteed Obligations or any part
thereof that diligent inquiry would reveal, and Guarantor hereby agrees that
Lender shall have no duty to advise Guarantor of information known to Lender
regarding such condition or any such circumstances.

         This Guaranty is binding upon Guarantor, its successors and assigns and
shall benefit Lender and its successors, endorses, transferees and assigns. All
references to Borrower and Lender herein shall include their respective
successors and assigns. This instrument shall be governed by, and construed and
interpreted in accordance with, the laws of the State of Georgia.



                                       4
<PAGE>   5

         Guarantor hereby irrevocably submits and consents and to the
non-exclusive jurisdiction of the State and Federal Courts located in the State
of Georgia with respect to any action or proceeding arising out of this Guaranty
or any matter arising herefrom or relating hereto. Any such action or proceeding
commenced by Guarantor against Lender will be litigated only in a Federal Court
located in the district, or a State Court in the State of Georgia and County of
Fulton and Guarantor waives any objection based on forum non conveniens and any
objection to venue in connection therewith.

         In any such action or proceeding, Guarantor waives personal service of
the summons and complaint or other process and papers therein and agrees that
any process or notice of motion or other application to any of said Courts or a
judge thereof, or any notice in connection with any proceedings hereunder may be
served (i) inside or outside such State by registered or certified mail, return
receipt requested, addressed to Guarantor at the address set forth below or
which Guarantor has previously advised Lender in writing and as indicated in the
records of Lender and service or notice so served shall be deemed complete five
(5) days after the same shall have been posted or (ii) in such other manner as
may be permissible under the rules of said Courts.

         Notwithstanding any other provision of this Guaranty to the contrary,
if the obligations of Guarantor hereunder would otherwise be held or determined
by a court of competent jurisdiction in any action or proceeding involving any
state corporate law or any state or federal bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other similar law affecting
the rights of creditors generally, to be void, invalid or unenforceable to any
extent on account of the amount of such Guarantor's liability under this
Guaranty, then notwithstanding any other provision of this Guaranty to the
contrary, the amount of such liability shall, without any further action by
Guarantor or any other person or entity, be automatically limited and reduced to
the highest amount that is valid and enforceable as determined in such action or
proceeding.

         This Guaranty may be executed in any number of counterparts and by
different parties to this Agreement on separate counterparts, each of which,
when so executed, shall be deemed an original, but all such counterparts shall
constitute one and the same agreement.

         TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, GUARANTOR AND LENDER
WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING INSTITUTED BY
EITHER OF THEM AGAINST THE OTHER WHICH PERTAINS DIRECTLY OR INDIRECTLY TO THIS
GUARANTY, ANY ALLEGED TORTIOUS CONDUCT BY GUARANTOR OR LENDER, OR, IN ANY WAY,
DIRECTLY OR INDIRECTLY, ARISING OUT OF OR RELATED TO THE RELATIONSHIP BETWEEN
GUARANTOR AND LENDER OR BORROWER AND LENDER. IN NO EVENT WILL LENDER BE LIABLE
FOR LOST PROFITS OR OTHER SPECIAL OR CONSEQUENTIAL DAMAGES.

         GUARANTOR HEREBY ACKNOWLEDGES THAT IT HAS BEEN ADVISED BY COUNSEL OF
ITS OWN SELECTION IN THE NEGOTIATION, EXECUTION AND DELIVERY OF THIS GUARANTY,
THAT LENDER HAS NO FIDUCIARY RELATIONSHIP TO GUARANTOR (BUT RATHER THE
RELATIONSHIP BETWEEN LENDER AND GUARANTOR IS SOLELY THAT OF CREDITOR AND
DEBTOR), AND THAT NO JOINT VENTURE EXISTS BETWEEN LENDER AND BORROWER OR BETWEEN
LENDER AND GUARANTOR.

         IN WITNESS WHEREOF, Guarantor has executed and delivered this Guaranty
under seal on day and year first above written.

                  hereafter approved by Lender in writing prior to their

                  hereof will be, the sole beneficial owner of the Collateral,
                  free and clear of any mortgage, lien, pledge, charge, security

         (c)      To the extent applicable, each Account, Chattel Paper,
                  Instrument, Document of Title, Intangible and Security which

                  terms against the party obligated to pay the same (the "Third
                  Party Debtor"), and the amount represented by the Undersigned
                  to Lender from time to time as owing by each Third Party
                  Debtor or by all Third Party Debtors will be the correct

                  Undersigned which can be asserted against Lender, whether in
                  any proceeding to enforce the Collateral, this General
                  Security Agreement or otherwise.

                  Inventory in transit from suppliers or in transit to
                  customers) and other tangible property is at and will be kept
                  at one of such locations or at such other locations as the
                  Undersigned shall specify in writing to Lender and, subject to
                  the provisions of this General Security Agreement, none of the
                  Collateral shall be moved therefrom without the prior written
                  consent of Lender.

         (g)      The Undersigned has full corporate power, authority and
                  capacity to execute, deliver and perform all of its

<PAGE>   5



         (j)      This General Security Agreement when duly executed and
                  delivered by the Undersigned will be a legal, valid and
                  binding obligation of the Undersigned, enforceable against it
                  in accordance with its terms, subject only as such enforcement
                  may be limited by bankruptcy, insolvency and any other similar
                  laws or proceedings relating to the enforcement of creditors'
                  rights generally and to the extent that equitable remedies
                  such as specific performance and injunction are in the
                  discretion of a court of competent jurisdiction.

         (k)      There is no charter, by-law, or capital stock provision of the
                  Undersigned and no provision of any indenture, mortgage, lease
                  or agreement, written or oral, to which the Undersigned is a
                  party or under which the Undersigned is obligated, nor to the
                  knowledge of the Undersigned is there any law, statute, rule
                  or regulation, or any judgment, decree or order of any court
                  or agency binding on the Undersigned, which would be violated,
                  contravened, breached by or under which default would occur as
                  a result of the execution and delivery of this General
                  Security Agreement or by the performance of any provision,
                  condition, covenant or other term hereof.

         (l)      There is no litigation, tax claim, proceeding or dispute in
                  progress, pending or, to the knowledge of the Undersigned,
                  threatened, against, relating to or affecting the Undersigned
                  or its property, the adverse determination of which might
                  adversely affect the Undersigned's financial condition or
                  operations or impair the Undersigned's ability to perform its
                  obligations hereunder or under any other instrument or
                  agreement required hereunder.

         (m)      The undersigned is solvent in the sense that the fair saleable
                  value of all of its assets exceeds the total amount of its
                  liabilities.

4.       COVENANTS OF THE UNDERSIGNED.

         So long as this General Security Agreement remains in effect, the
Undersigned hereby covenants and agrees that:

         (a)      Without the prior written consent of Lender, the Undersigned
                  shall not assume, create or permit the creation of any
                  mortgage, lien, charge, pledge, security interest,
                  hypothecation or encumbrance whatsoever (other than a
                  Permitted Lien) on any of the Collateral, including, without
                  limiting the generality of the foregoing, any purchase money
                  security interest as defined in the Code.

         (b)      The Undersigned shall diligently defend its title to the
                  Collateral against the claims and demands of all persons
                  claiming the same or an interest therein.


                                        5

<PAGE>   6



         (c)      The Undersigned shall diligently maintain, use and operate the
                  Collateral and shall carry on and conduct its business in a
                  proper and efficient manner so as to preserve and protect the
                  Collateral and the earnings, incomes, rents, issues and
                  profits thereof.

         (d)      The Undersigned shall (i) cause the Collateral to be properly
                  insured and kept properly insured with reputable insurers as
                  shall be acceptable to Lender against loss or damage by fire,
                  windstorm, water, theft, malicious mischief and extended
                  coverage, and such other risks as Lender may require, to the
                  full insurable value thereof, (ii) either assign the insurance
                  policies to Lender or have the loss thereunder made payable to
                  Lender, as Lender may require, (iii) deliver to Lender the
                  originals of such policies or certified copies thereof with

                  insured, as appropriate, and (iv) deliver to Lender evidence
                  of such insurance satisfactory to Lender. Should the
                  Undersigned neglect to maintain such insurance, Lender may
                  (but shall not be required to) insure the Collateral, and any
                  premiums paid by Lender together with interest thereon shall
                  be payable by the Undersigned to Lender upon demand.

         (e)      The Undersigned shall keep the Collateral free and clear of
                  all taxes, assessments, claims, liens and encumbrances except
                  for ("Permitted Liens"):

                  (i)      security interests and liens at any time granted in
                           favor of Lender;

                  (ii)     liens for taxes that are not yet due or are being
                           contested in good faith by the Undersigned by
                           appropriate proceedings promptly instituted and
                           diligently conducted, when the Undersigned has
                           established appropriate reserves therefor, but only
                           if nonpayment of such taxes will not have a material
                           adverse effect upon the business, operations,
                           properties, condition (financial or otherwise), or
                           the business prospects of the Undersigned or the
                           Collateral and no lien is imposed upon the
                           Undersigned's assets with respect to such taxes
                           unless such lien is at all times junior and
                           subordinate in priority to the security interests and
                           liens in favor of Lender;

                  (iii)    statutory liens arising in the ordinary course of the
                           Undersigned's business by operation of law or
                           regulation, but only if (a) payment in respect of any
                           such lien is not at the time required or such liens
                           are being contested in good faith by the Undersigned
                           by appropriate proceedings promptly instituted and
                           diligently conducted, when the Undersigned has
                           established appropriate reserves therefor, (b) such
                           liens do not, in the aggregate, materially detract
                           from the value of the Collateral or materially impair
                           the use thereof in the operation of the Undersigned's
                           business, and (c) such liens are at all times junior
                           and subordinate to the security interests and liens
                           in favor of Lender; and

                  (iv)     such other liens as Lender may hereafter approve in
                           writing.

         (f)      The Undersigned shall pay all rents, taxes, rates, levies,
                  assessments, government fees, dues and other charges of every
                  nature lawfully levied, assessed or imposed against or in
                  respect of the Undersigned or the Collateral or any part
                  thereof as and when the same shall become due and payable, and
                  shall exhibit to Lender, when required, the receipts and
                  vouchers establishing such payments.

         (g)      The Undersigned shall preserve and maintain its corporate
                  existence, rights, franchises and privileges and shall duly
                  observe and conform to all valid requirements of any
                  governmental authority relative to its business, credit or any
                  of the Collateral and all covenants, terms and conditions upon
                  or under which the Collateral is held.

         (h)      The Undersigned shall notify Lender in writing:

                  (i)      promptly after the Undersigned's learning thereof, of
                           the commencement of any litigation or claims before
                           any court, administrative board or other tribunal
                           relating to or affecting the Undersigned or any of
                           its properties, whether or not the claim is
                           considered by the Undersigned to be covered by
                           insurance;

                  (ii)     of the occurrence of any event or the existence of
                           any fact which renders any representation or warranty
                           in this General Security Agreement inaccurate,
                           incomplete or misleading;

                  (iii)    promptly after the Undersigned's learning thereof, of
                           any default by the Undersigned under any note
                           indenture, loan agreement, mortgage, lease, deed,
                           guaranty or other similar agreement relating to any
                           indebtedness of the Undersigned exceeding $300,000;

                  (iv)     promptly after the occurrence thereof, of any Event
                           of Default;

                  (v)      promptly after the occurrence thereof, of any default
                           by any obligor under any note or other evidence of
                           indebtedness payable to the Undersigned;

                  (vi)     promptly after the occurrence thereof, of any
                           judgment rendered against the Undersigned in an
                           amount exceeding $300,000;

                  (vii)    at least thirty (30) days prior to the occurrence
                           thereof, the details of any proposed material
                           acquisition of Collateral and, promptly after the
                           occurrence thereof, the details of any acquisition of
                           any vehicle, mobile home, trailer, boat, aircraft or
                           aircraft engine;

<PAGE>   8



                  (viii)   promptly after the Undersigned's learning thereof, of
                           any event which occurs that would have an adverse
                           effect upon the Collateral or upon the financial
                           condition of the Undersigned, including, without
                           limiting the generality of the foregoing, any loss of
                           or damage to the Collateral, any default by any Third
                           Party Debtors in the payment or other performance of
                           its obligations with respect to the Collateral or the
                           return to or repossession by the Undersigned of
                           Collateral where such return or repossession of
                           Collateral is material in relation to the business of
                           the Undersigned; and

                  (ix)     promptly (and in any event within 2 Business Days)
                           after the Undersigned's learning thereof, of the
                           termination of or assertion by a landlord of the
                           Undersigned of any default under any lease between
                           such landlord and the Undersigned.

         (i)      The Undersigned shall not sell, exchange, transfer, lease,
                  assign or otherwise dispose of or change the use of the
                  Collateral or any interest therein (except for sales of
                  Inventory in the ordinary course of the Undersigned's business
                  so long as no Event of Default exists hereunder) or modify,
                  amend, discount, compromise or terminate any Chattel Paper,
                  Document of Title, Instrument, Security, Intangible or
                  Accounts, or assign, factor or discount any of the Accounts to
                  a third party, without the prior written consent of Lender.
                  All proceeds of the Collateral shall be held in trust by the
                  Undersigned for Lender.

         (j)      The Undersigned shall prevent the Collateral, except the
                  Collateral sold or leased as permitted hereby, from being or
                  becoming an accession to other property not covered by this
                  General Security Agreement.

         (k)      The Undersigned shall not create or permit the creation of any
                  trust deed or similar instrument without the prior written
                  consent of Lender.

         (l)      The Undersigned shall keep proper books of account in
                  accordance with sound accounting practice and complete and
                  accurate records concerning the Collateral. The Undersigned
                  shall from time to time forthwith, on request, furnish to
                  Lender in writing all information and statements, including
                  financial information and statements, requested relating to
                  the Undersigned's business, the Collateral or any part
                  thereof, and Lender or its authorized agents shall be entitled
                  from time to time to inspect the tangible Collateral wherever
                  located, including, without limiting the generality of the
                  foregoing, the books and records, financial or otherwise,
                  maintained by the Undersigned with respect to the Collateral,
                  and to make copies thereof and take extracts therefrom, and
                  for such purpose Lender or its authorized agents shall have
                  access to all places where the Collateral or any part thereof
                  is located and to all premises occupied by the Undersigned.


                                        8

<PAGE>   9



         (m)      The Undersigned shall keep all Collateral, other than
                  Inventory in transit, at one or more locations set forth in
                  Schedule A attached hereto, and all such Collateral shall not,
                  without the prior written consent of Lender, be moved
                  therefrom, except prior to an Event of Default, for (i) sales
                  of Inventory in the ordinary course of business and (ii) the
                  storage of Inventory at locations within Maryland and Georgia
                  other than those shown on Schedule A if, prior to storage of
                  any such Inventory at such locations, all filings that are
                  necessary to perfect or continue to perfect Lender's security
                  interests in or liens upon the Collateral have been filed.

         (n)      The Undersigned shall provide Lender with all agreements
                  hereafter entered into between the Undersigned and any
                  landlord or warehouseman which owns any premises at which any
                  Inventory may hereafter be kept. The Undersigned shall obtain
                  a lien waiver or subordination, in the form requested by
                  Lender, from each landlord of a premises leased by the
                  Undersigned.

         (o)      The Undersigned shall furnish Lender with Inventory reports,
                  which reports shall describe the Inventory by each location
                  and be substantially in the form requested by Lender, at such
                  times as Lender may request. The Undersigned shall conduct a
                  physical inventory no less frequently than annually and shall
                  provide to Lender reports based on each such physical
                  inventory promptly thereafter, together with such supporting
                  information as Lender shall reasonably request.

         (p)      The Undersigned shall deliver to Lender from time to time
                  promptly upon request such other information concerning the
                  Collateral, the Undersigned and the Undersigned's business and
                  affairs as Lender may reasonably request.

         (q)      The Undersigned shall not change its name or the location of
                  its chief executive office or principal place of business
                  without having given Lender at least sixty (60) days prior
                  written notice thereof.

5.       USE AND VERIFICATION OF COLLATERAL.

         Subject to compliance with the Undersigned's covenants contained herein
and paragraph 7 hereof, the Undersigned may, until an Event of Default, possess,
operate, collect, use, enjoy and deal with the Collateral in the ordinary course
of the Undersigned's business in any lawful manner not inconsistent with the
provisions of this General Security Agreement; provided always that Lender shall
have the right at any time and from time to time to verify the existence and
state of the Collateral in any manner Lender may consider appropriate and the
Undersigned agrees to furnish all assistance and information and to perform all
such acts as Lender may request in connection therewith and for such purpose,
the Undersigned shall permit Lender and its representatives, from time to time,
and as often as may be requested, but only during normal business hours, to (i)
visit and inspect the properties at which any Collateral is located, (ii)
inspect, audit and make extracts from its books and records and (iii) discuss
with the Undersigned's officers, employees and

                                        9

<PAGE>   10



independent accountants, the Undersigned's business, assets, liabilities,
financial condition, business prospects and results of operations.

6.       SECURITIES.

         If Collateral at any time includes Securities, the Undersigned hereby
authorizes Lender to transfer the same or any part thereof into its own name or
that of its nominee(s) so that Lender or its nominee(s) may appear of record as
the sole registered owner thereof; provided, that, until the occurrence of Event
of Default, Lender shall deliver promptly to the Undersigned all notices or
other communications received by it or its nominee(s) as such registered owner
and, upon demand and receipt of payment of any reasonable expenses in connection
thereof, shall issue to the Undersigned or its order a proxy to vote and take
all action with respect to such Securities. After the occurrence of an Event of
Default, the Undersigned waives all rights to receive any notices or
communications received by Lender or its nominee(s) as such registered owner and
agrees that no proxy issued by Lender to the Undersigned or its order as
aforesaid shall thereafter be effective. Lender shall be entitled but not bound
or required to vote in respect of such Securities at any meeting at which the
holder thereof is entitled to vote and, generally, to exercise any of the rights
which the holder of such Securities may at any time have; provided, that, Lender
shall not be responsible for any loss occasioned by the exercise of any of such
rights or by the failure to exercise the same within the time limited for the
exercise thereof.

7.       COLLECTION AND VERIFICATION OF ACCOUNTS AND OTHER DEBTS.

         To expedite collection, the Undersigned shall endeavor to make
collection of its Accounts and all debts evidenced by its Chattel Paper or its
Instruments for Lender. Any of Lender's officers, employees or agents shall have
the right, at any time or times thereafter, in the name of Lender, any designee
of Lender or the Undersigned, to verify the validity, amount or any other matter
relating to any Account with the account debtor of such Account by mail,
telephone, telecopier or otherwise. The Undersigned shall cooperate fully with
Lender to facilitate and promptly conclude any such verification process.

8.       PROCEEDS, INCREASES, PROFITS, PAYMENTS OR DISTRIBUTIONS.

         Whether or not an Event of Default has occurred, Lender may take
control of or receive all proceeds of, income from or interest on Collateral and
may apply any money taken as Collateral to the satisfaction of the Obligations
secured hereby. Lender may hold as additional security any increase or profits
received from any Collateral in Lender's possession, may receive any payment or
distribution upon redemption or retirement of the Collateral or upon the
dissolution or liquidation of the issuer of the Collateral and may apply any
money received from such Collateral to reduce the Obligations secured hereby and
may hold any balance as additional security for such part of the Obligations as
may not yet be due, whether absolute or contingent. If the Undersigned receives
any such increase or profits or payments or distributions, the Undersigned will
deliver the same promptly to Lender to be held by Lender as herein provided.
Lender will not be obligated to keep any


                                       10

<PAGE>   11



Collateral separate or identifiable. In the case of any Instrument, Security or
Chattel Paper, Lender will not be obligated to take any necessary or other steps
to preserve rights against other persons.

9.       EVENT OF DEFAULT.

         The occurrence of one or more of the following events shall constitute
an "Event of Default":

         (a)      The Undersigned shall default in the payment of all or any
                  part of the Obligations of the Undersigned to Lender as the
                  same falls due, whether by acceleration or otherwise.

         (b)      The Undersigned shall default in the performance or observance
                  of any covenant, obligation, term, condition, undertaking,
                  provision or agreement heretofore, herein or hereafter given
                  to Lender, whether contained herein or in any other agreement
                  to which the Undersigned and Lender are parties, including,
                  without limiting the generality of the foregoing, any covenant
                  or undertaking set out in the Guaranty.

         (c)      Any of the representations and warranties heretofore, herein
                  or hereafter given to Lender is or becomes incorrect in any
                  respect at any time or any certificate, statement or audit
                  report heretofore, herein or hereafter given or delivered to
                  Lender is incorrect in any respect at the time such
                  certificate, statement or audit report is given or delivered
                  to Lender.

         (d)      If any execution, judgment or any other process of any court
                  shall become enforceable against the Undersigned or any
                  guarantor of any of the Obligations or any distress or
                  analogous process shall be levied upon the Collateral or any
                  part thereof.

         (e)      The Undersigned or any guarantor of any of the Obligations
                  shall become insolvent, file a bankruptcy petition, make an
                  assignment in bankruptcy, make a bulk sale of its assets or
                  otherwise transfer all or substantially all of its assets,
                  propose a compromise or arrangement to its creditors or take
                  advantage of provisions for relief under the U.S. Bankruptcy
                  Code or any other legislation for the benefit of insolvent
                  debtors.

         (f)      If a bankruptcy petition shall be filed or presented against
                  the Undersigned or any guarantor of any of the Obligations and
                  not be bona fide opposed by the Undersigned or any guarantor
                  of any of the Obligations, any proceeding is taken, whether in
                  court or under the terms of any agreement or appointment in
                  writing, with respect to a compromise or arrangement to have
                  the Undersigned or any guarantor of any of the Obligations
                  dissolved, liquidated or wound up, or to have a receiver or
                  similar official appointed in respect of the Undersigned or
                  any guarantor of any of the Obligations or of any part of the
                  Collateral, or if any encumbrance becomes


                                       11

<PAGE>   12



                  enforceable against any Collateral or any encumbrancer takes
                  possession of any part thereof.

         (g)      The Undersigned or any guarantor of any of the Obligations
                  shall cease or threaten to cease to carry on business for a
                  period which significantly affects the Undersigned's capacity
                  to continue its business, on a profitable basis; or the
                  Undersigned shall suffer the loss or revocation of any license
                  or permit now held or hereafter acquired by the Undersigned
                  which is necessary to the continued or lawful operation of its
                  business; or the Undersigned shall be enjoined, restrained or
                  in any way prevented by court, governmental or administrative
                  order from conducting all or any material part of its business
                  affairs.

         (h)      An Event of Default shall have occurred under (and as defined
                  in) the Loan and Security Agreement dated December 21, 1995,
                  between Lender and Borrower, as modified, amended or otherwise
                  altered (the "Loan Agreement").

         (i)      If the Undersigned enters into any reorganization, merger or
                  other similar arrangement.

         (j)      The Undersigned shall be criminally indicted or convicted
                  under any law that could lead to forfeiture of any property of
                  the Undersigned.

         (k)      Lender shall have commercially reasonable grounds to believe
                  that the prospect of payment of the Obligations or performance
                  of the obligations under this General Security Agreement or
                  under any other agreement between the Undersigned and Lender
                  are about to be impaired or that the Collateral is about to be
                  in danger of being lost, damaged, confiscated or placed in
                  jeopardy.

         (l)      The Undersigned or any other guarantor of all or any part of
                  the Obligations shall revoke or attempt to revoke its
                  guaranty.

The provisions of this clause are not intended in any way to affect any rights
of Lender with respect to any Obligations which may now or hereafter be payable
on demand.

10.      REMEDIES ON DEFAULT.

         (a)      Upon or at any time after the occurrence of any Event of
                  Default, Lender, at its sole discretion, may declare all or
                  any part of the Obligations, whether or not any such
                  Obligation is not by its terms payable on demand, to be
                  immediately due and payable in full, without demand or notice
                  of any kind.

         (b)      If Lender declares that the Obligations shall immediately
                  become due and payable in full, Lender may withhold any future
                  advances, may proceed to enforce payment


                                       12

<PAGE>   13



                  of the Obligations, take immediate possession of the
                  Collateral, enter upon any premises of the Undersigned,
                  otherwise enforce this General Security Agreement and enforce
                  any rights of the Undersigned in respect of the Collateral by
                  any manner permitted by applicable law, and may use the
                  Collateral in the manner and to the extent that Lender may
                  consider appropriate and may hold, insure, repair, process,
                  maintain, preserve, prepare for disposition and dispose of the
                  same and may require the Undersigned to assemble and deliver
                  the Collateral or make the Collateral available to Lender at a
                  place designated by Lender. Lender may also take proceedings
                  in any court of competent jurisdiction for the appointment of
                  a receiver (which term shall include a receiver and manager)
                  of the Collateral or of any part thereof or may by instrument
                  in writing appoint any person to be a receiver of the
                  Collateral or of any part thereof and may remove any receiver
                  so appointed by Lender and appoint another in his stead; and
                  any such receiver appointed by instrument in writing shall, to
                  the extent permitted by applicable law or to such lesser
                  extent permitted, have all of the rights, remedies, benefits
                  and powers of Lender hereunder or under the Code or otherwise
                  and, without limiting the generality of the foregoing, have
                  power (i) to take possession of the Collateral or any part
                  thereof, (ii) to carry on or concur in carrying on all or any
                  part or parts of the business of the Undersigned, (iii) to
                  file such proofs of claim and other documents as may be
                  necessary or advisable in order to have his claim lodged in
                  any bankruptcy, winding-up or other judicial proceedings
                  relative to the Undersigned, (iv) to borrow money required for
                  the seizure, repossession, retaking, repair, insurance,
                  maintenance, preservation, protection, collection, preparation
                  for disposition, disposition or realization of the Collateral
                  or any part thereof and for the enforcement of this General
                  Security Agreement or for the carrying on of the business of
                  the Undersigned on the security of the Collateral in priority
                  to the security interest created under this General Security
                  Agreement, and (v) to sell, lease or otherwise dispose of, or
                  concur in the sale, lease or other disposition of, the whole
                  or any part of the Collateral at public auction, by public
                  tender or by private sale, lease or other disposition, either
                  for cash or upon credit, at such time and upon such terms and
                  conditions as the receiver may determine, provided that if any
                  such disposition involves a deferred payment or payments,
                  Lender will not be accountable for and the Undersigned will
                  not be entitled to be credited with the proceeds of any such
                  disposition until the monies therefor are actually received.
                  Any such receiver shall for all purposes be deemed to be the
                  agent of the Undersigned. Lender may from time to time fix the
                  remuneration of such receiver. All moneys from time to time
                  received by such receiver shall be paid by him first in
                  discharge of the reasonable expenses of Lender incurred in
                  retaking, holding, repairing, processing and preparing for
                  disposition and disposing of the Collateral including, without
                  limitation, all rents, taxes, rates, insurance premiums and
                  outgoings affecting the Collateral, remuneration of the
                  receiver, such other amounts referred to in subparagraph 12(b)
                  hereof, costs of keeping in good standing any liens and
                  charges on the Collateral prior to the security constituted by
                  this General Security Agreement and any other reasonable
                  expenses

                                       13

                  incurred by Lender, and secondly in or toward payment of such
                  parts of the Obligations of the Undersigned to Lender in such
                  manner and order as Lender may in its sole discretion
                  determine, and any residue of such moneys so received shall be
                  paid to the Undersigned. Lender in appointing or refraining
                  from appointing such receiver shall not incur any liability to
                  the receiver, the Undersigned or otherwise and shall not in
                  any way be responsible for any misconduct or negligence of any
                  such receiver.

         (c)      In addition to the rights and remedies specifically provided
                  herein, Lender shall, upon the occurrence of an Event of
                  Default, have the rights and remedies of a secured party under
                  the Code and other applicable legislation and as otherwise
                  provided by applicable law.

         (d)      If the disposition of the Collateral fails to satisfy all of
                  the Obligations, the Undersigned shall be liable to pay for
                  any deficiency on demand.

         (e)      When required to do so by the Code, Lender shall give to the
                  Undersigned the written notice required by the Code of any
                  intended disposition of the Collateral by serving such notice
                  personally on the Undersigned or by mailing such notice by
                  registered mail to the last known address of the Undersigned
                  or by any other method authorized or permitted by the Code.

11.      ACCOUNTS.

         In addition to the remedies set out in paragraph 10 hereof, Lender may
collect, realize, sell or otherwise deal with the Accounts or any part thereof
in such manner, upon such terms and conditions and at such time or times after
the occurrence of an Event of Default as may seem to it advisable and without
notice to the Undersigned (except in the case of sale and then subject to
subparagraph 10(e) hereof). Lender shall not be liable or accountable for any
failure to collect, realize, sell or obtain payment of the Accounts or any part
thereof and shall not be bound to institute proceedings for the purpose of
collecting, realizing or obtaining payment of the same or for the purpose of
preserving any rights of Lender, the Undersigned or any other person, firm or
corporation in respect of the same. All moneys collected or received by the
Undersigned in respect of the Accounts shall be received as trustee for Lender
and shall be forthwith paid over to Lender. All moneys collected or received by
Lender in respect of the Accounts or other Collateral may be applied, after
deduction of the reasonable expenses of realization from the money collected and
subject to any applicable requirements of the Code, on account of such parts of
the Obligations of the Undersigned as to Lender deems best or in the discretion
of Lender may be released to the Undersigned, all without prejudice to the
liability of the Undersigned or Lender' right to hold and realize this security.

12.      CHARGES AND EXPENSES.

         (a)      Upon the Undersigned's failure to perform any of its duties
                  hereunder, Lender may, but shall not be obligated to, perform
                  any or all of such duties, without waiving any rights to
                  enforce this General Security Agreement, and the Undersigned
                  shall pay to Lender, forthwith upon written demand therefor,
                  an amount equal to the costs, fees and expenses incurred by
                  Lender in so doing (including, without limiting the generality
                  of the foregoing, costs, fees and expenses associated with
                  legal advice and services).

         (b)      Lender may charge on its own behalf and pay to others
                  reasonable sums for costs, fees and expenses incurred and for
                  services rendered (including, without limiting the generality
                  of the foregoing, legal advice and services) in or in
                  connection with seizing, repossessing, retaking, repairing,
                  insuring, realizing, disposing of, retaining or collecting the
                  Collateral or any part thereof, and such sums shall be a first
                  charge on the proceeds of such realization, disposition or
                  collection. Subject to any applicable requirements of the Code
                  and the provisions of paragraph 10 hereof, the proceeds of any
                  such disposition of any Collateral may be applied by Lender to
                  the payment of all such costs, fees and expenses and any
                  balance of such proceeds may be applied by Lender towards the
                  payment of the Obligations in such order of application as
                  Lender may from time to time determine.

         (c)      All of the above costs, fees and expenses and all amounts
                  borrowed on the security of the Collateral under paragraph 10
                  hereof shall bear interest at a rate equal to two percent
                  (2.0%) per annum above the Interest Rate (as such term is
                  defined in the Loan Agreement) then in effect under the Loan
                  Agreement and shall be Obligations under this General Security
                  Agreement.

13.      FURTHER ASSURANCES.

         The Undersigned shall from time to time forthwith on Lender's request
furnish further assurance of title to the Collateral and further security to
Lender and execute and deliver all such financing statements, further
assignments, documents and instruments, and do or make all such further acts,
matters and things as may be required by Lender with respect to the Collateral
or any part thereof or as may be required or desirable to give effect to the
purposes and provisions of this General Security Agreement, and the Undersigned
further covenants and agrees to pay all costs and expenses incurred in
connection therewith. The Undersigned hereby irrevocably constitutes and
appoints Lender the true and lawful attorney of the Undersigned, with full power
of substitution, to do, make, sign, execute and deliver on behalf of the
Undersigned all such statements, assignments, documents, instruments, acts,
matters and things, as the Undersigned has agreed by these presents to do, make,
sign, execute or deliver or as may be required by Lender to give effect to these
presents or in the exercise of the powers on Lender hereby conferred, with the
right to use the name of the Undersigned, whenever and wherever Lender may deem
it necessary or expedient to do so. The power of attorney granted herein may be
exercised in the name and on behalf of the successors or

                                       15

<PAGE>   16



assigns of the Undersigned. None of the powers hereby granted shall be revoked
by the bankruptcy of the Undersigned.

14.      DEALINGS BY LENDER.

         Lender may grant extensions of time, additional advances, renewals,
extensions and other indulgences, take and give up securities, accept
compositions, grant releases and discharges and otherwise deal with the
Undersigned, debtors of the Undersigned, sureties and others and with the
Collateral and other securities as Lender may see fit without prejudice to the
liability of the Undersigned or Lender's rights under this General Security
Agreement.

15.      GENERAL.

         The Undersigned and Lender further agree that:

         (a)      This General Security Agreement shall constitute and be a
                  continuing security agreement in every respect, shall not be
                  considered as satisfied or discharged by any intermediate
                  payment of all or any part of the Obligations and shall be in
                  addition to and not in substitution for any other security now
                  or hereafter held by Lender.

         (b)      Nothing in this General Security Agreement shall obligate
                  Lender to make any loan or accommodation to the Undersigned or
                  to grant, continue, renew or extend the time for payment or
                  satisfaction of the Obligations.

         (c)      Any failure by Lender to exercise any right set out in this
                  General Security Agreement shall not constitute a waiver
                  thereof. No remedy for the enforcement of the rights of Lender
                  hereunder shall be exclusive of or dependent on any other such
                  remedy but any one or more of such remedies may from time to
                  time be exercised in whole or in part, independently or in
                  combination.

         (d)      The security interests and liens created or provided for by
                  this General Security Agreement are intended to attach to
                  Collateral existing when this General Security Agreement is
                  signed by the Undersigned and delivered to Lender (or in the
                  case of property acquired subsequent thereto, immediately upon
                  the Undersigned acquiring any rights in such property). The
                  Undersigned acknowledges that it has received value and has
                  (or in the case of after acquired property, will have) rights
                  in the Collateral. The parties do not intend to postpone the
                  attachment of any security interest or lien created hereby.
                  For greater certainty, it is declared that any and all future
                  loans, advances or other value which Lender may in its
                  discretion make or extend to or for the account of the
                  Undersigned shall be secured by this General Security
                  Agreement.


                                       16

         (e)      All rights of Lender hereunder shall be assignable and in any
                  action brought by an assignee to enforce such rights, the
                  Undersigned shall not assert against the assignee any claim or
                  defense which the Undersigned now has or may hereafter have
                  against Lender.

         (f)      This General Security Agreement shall inure to the benefit of
                  and be binding upon Lender and the Undersigned, their
                  successors and assigns.

         (g)      If the Collateral or any part thereof is being sold or
                  delivered to the Undersigned by Lender, title and ownership of
                  each part of the Collateral shall not pass to the Undersigned
                  but shall be and remain in Lender until all Obligations in
                  respect of each such part are paid or performed in full.

         (h)      If more than one person executes this General Security
                  Agreement, then obligations hereunder shall be joint and
                  several and the Obligations shall include those of all or any
                  one or more of them.

         (i)      This General Security Agreement may be executed in one or more
                  counterparts, each of which when so executed shall be deemed
                  to be an original and such counterparts together shall
                  constitute one and the same instrument. Any signature
                  delivered by a party by facsimile transmission shall be deemed
                  to be an original signature hereto.

         (j)      In this General Security Agreement words importing number
                  shall include the singular and the plural, words importing
                  gender shall include all genders and the word "person" shall
                  include all firms, corporations, trusts, partnerships and
                  other forms of association.

         (k)      The headings of the paragraphs hereof are inserted for
                  convenience of reference only and shall not affect the
                  interpretation or construction of this General Security
                  Agreement.

         (l)      Time shall be of the essence of this General Security
                  Agreement and of each and every part hereof.

         (m)      This General Security Agreement shall be deemed effective upon
                  Lender's acceptance thereof. This General Security Agreement
                  will be governed in all respects by the laws of the State of
                  Georgia.

         (n)      No modification of or amendment to this General Security
                  Agreement shall be valid or binding unless set forth in
                  writing and duly executed by the Undersigned and Lender and no
                  waiver of any breach of any term or provision of this General
                  Security Agreement shall be effective or binding unless made
                  in writing and signed by the

                                       17

<PAGE>   18



                  party purporting to give the same and, unless otherwise
                  provided, shall be limited to the specific breach waived.

         (o)      Any provision of this General Security Agreement, as amended
                  from time to time, which is prohibited or unenforceable in any
                  jurisdiction shall, as to such jurisdiction, be ineffective to
                  the extent of such prohibition or unenforceability without
                  invalidation of the remaining provisions hereof or affecting
                  the validity or enforceability of such provision in any other
                  jurisdiction.

                          AGREEMENT AND PLAN OF MERGER

         THIS AGREEMENT AND PLAN OF MERGER (the "Agreement") is made as of the
11th day of April, 1997, by and among HAYES MICROCOMPUTER PRODUCTS, INC., a
Georgia corporation ("Hayes"), CARDINAL TECHNOLOGIES, INC., a Pennsylvania
corporation (the "Company"), VULCAN VENTURES INCORPORATED, a Washington
corporation ("Vulcan"), and the direct subsidiary of Hayes, HAYES MERGER SUB.,
INC., a Pennsylvania corporation ("Merger Sub").

                                   BACKGROUND

         A.       On March 12, 1997, Hayes, the Company and Vulcan entered into
that certain letter of intent for the purpose of proceeding with an all cash
merger between Merger Sub and the Company (the "Letter of Intent").

         B.       This Agreement and Plan of Merger constitutes the Definitive
Agreement as described in the Letter of Intent.

                                    AGREEMENT

         In consideration of the mutual promises, covenants and conditions
hereinafter set forth, the parties hereby agree as follows:

         1.       Plan of Merger.

                  1.1      Terms and Conditions of Merger.

                           (a)      Merger.  Prior to the date hereof, Hayes has
formed Merger Sub, a directly owned subsidiary formed under the Pennsylvania
Business Corporation Law (the "Pennsylvania BCL") for the purpose of
accomplishing the merger described herein. Upon the terms and subject to the
conditions set forth herein and in accordance with the Pennsylvania BCL, at the
Effective Time, Merger Sub shall be merged with and into the Company (the
"Merger"), and the separate existence of Merger Sub shall cease. The Company
shall be the surviving corporation in the Merger (sometimes hereinafter referred
to as the "Surviving Corporation"). At the Closing Merger Sub and the Company
shall cause Articles of Merger in the form attached hereto as Exhibit "1.1(a)"
(the "Articles of Merger"), together with all other required certifications,
filings and instruments, to be duly filed with the Secretary of State of the
Commonwealth of Pennsylvania and cause all fees associated therewith to be paid.
The Merger

                                        1


<PAGE>   2



shall be effective at the time of such filings with the said Secretary of State
(the "Effective Time").

                           (b)      Conversion of Common Shares.  At the
Effective Time, each outstanding share of capital stock of the Company (the
"Company Shares"), other than Company Shares held in the treasury of the Company
which shall be canceled and retired, shall be converted into and evidence the
right to receive an amount per Company Share equal to Two Million Five Hundred
Thousand Dollars ($2,500,000) (the "Merger Consideration") divided by the
aggregate number of Company Shares outstanding immediately prior to the
Effective Time (the "Merger Consideration Per Share"). At the Effective Time,
each outstanding common share, par value $.01 per share, of Merger Sub shall be
converted into one common share, par value $.01 per share, of the Surviving
Corporation.

                           (c)      Stock Options.  At the Effective Time, all
unexercised options to purchase Company Shares shall be converted into the right
to receive the Merger Consideration Per Share upon proper exercise of such
option.

                           (d)      Dissenting Shares.  Notwithstanding anything
in this Agreement to the contrary, Company Shares outstanding immediately prior
to the Effective Time and held by a holder who has not voted in favor of the
Merger or consented thereto in writing, and who has demanded to be paid the fair
value of such Company Shares in accordance with Chapter 15, Subchapter D of the
Pennsylvania BCL ("Dissenting Shares"), shall not be converted into the right to
receive the Merger Consideration , unless such holder fails to perfect or
withdraws or otherwise loses his right to appraisal but shall be canceled and
converted into the right, if and to the extent perfected in accordance with
applicable law, to receive the "fair value" thereof as determined in accordance
with the Pennsylvania BCL. If, after the Effective Time, such holder fails to
perfect or withdraws or loses his right to appraisal, such Company Shares shall
be treated as if they had been converted as of the Effective Time into the right
to receive the Merger Consideration, without interest thereon, upon surrender of
the certificate or certificates formerly representing such Company Shares less
any required withholding of taxes. The Company shall give Hayes and Merger Sub
prompt notice of all demands received by the Company for appraisal of Company
Shares prior to the Effective Time and the Surviving Corporation shall give
Vulcan prompt notice of all demands received by the Company for appraisal of
Company Shares after the Effective Time. Vulcan shall have the right and
obligation to direct all negotiations and proceedings with respect to such
demands.

                           (e)      Articles of Incorporation; Bylaws; Officers
and Directors. The Articles of Incorporation and Bylaws of the Company shall be
amended and restated as of the Effective Time so that the Articles of
Incorporation and Bylaws of Merger Sub, copies of which are attached hereto as
Exhibit "1.1(e)," shall be the Amended and Restated Articles of Incorporation
and Bylaws of the Surviving Corporation following the Merger. At the Effective
Time, the Board of Directors of the Company shall no longer be the Board of
Directors of the Surviving Corporation. At the Effective Time, the officers of
the Company shall no longer be the officers of the Surviving Corporation. The
Board of Directors and the officers of Merger Sub

                                        2


<PAGE>   3



shall become, at the Effective Time, the Board of Directors and officers of the
Surviving Corporation.

                           (f)      Formation and Capitalization of Merger Sub.
Prior to the Effective Time, Hayes shall cause Merger Sub to take all such
corporate and other actions necessary to consummate the transactions
contemplated by this Agreement. Hayes agrees to vote its Merger Sub Stock in
favor of the Merger. Subject to the terms and conditions of this Agreement,
Hayes agrees to capitalize Merger Sub in at least the amount of Two Million Five
Hundred Thousand and No/Hundredths Dollars ($2,500,000.00).

                           (g)      Shareholder Approval.  The Company has or
shall prior to Closing take such actions as are necessary in accordance with
applicable law to obtain the approval of its shareholders to this Agreement, the
Merger and the consummation of the transactions contemplated hereby.

                           (h)      Payment for Company Shares .  Promptly after
the Effective Time, the Surviving Corporation shall mail to each record holder,
as of the Effective Time, of an outstanding certificate or certificates which
immediately prior to the Effective Time represented Company Shares (the
"Certificates"), a form letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon proper delivery of the Certificates to the Surviving Corporation) and
instructions for effecting the surrender of the Certificates for payment of the
Merger Consideration. Upon surrender to the Surviving Corporation of a
Certificate (or an affidavit as to its loss with an appropriate indemnity),
together with a duly executed letter of transmittal and any other required
documents, the holder of such Certificate shall receive in exchange therefor (as
promptly as practicable) the Merger Consideration Per Share, without any
interest thereon, less any required withholding of taxes, and such Certificate
shall forthwith be canceled. If payment is to be made to a person other than the
person in whose name a Certificate so surrendered is registered, it shall be a
condition of payment that the Certificate so surrendered shall be properly
endorsed or otherwise in proper form for transfer, that the signatures on the
Certificate or any related stock power shall be properly guaranteed and that the
person requesting such payment shall either pay any transfer or other taxes
required by reason of the payment to a person other than the registered holder
of the Certificate so surrendered or establish to the satisfaction of Vulcan and
the Surviving Corporation that such tax has been paid or is not applicable.
Until surrendered in accordance with the provisions of this 1.1(h), each
Certificate (other than (i) Certificates representing Company Shares held in the
Company's treasury which shall be canceled at the Effective Time, or (ii)
Certificates representing Dissenting Shares, which shall represent for all
purposes only the right, if perfected, to receive fair value as provided in
Section 1.1(d)) shall represent for all purposes only the right to receive the
Merger Consideration Per Share. After the Effective Time, there shall be no
transfers on the stock transfer books of the Surviving Corporation of the
Company Shares which were outstanding immediately prior to the Effective Time.
If, after the Effective Time, Certificates are presented to the Surviving
Corporation, they shall be canceled and exchanged for the Merger Consideration
Per Share in accordance with procedures set forth in this Section 1.1(h). From
and after the Effective Time, the holders of Certificates evidencing ownership
of Company Shares outstanding immediately prior to the Effective Time shall

                                        3


<PAGE>   4



cease to have any rights with respect to such Company Shares except as otherwise
provided herein or by applicable law. Such holders shall have no rights, after
the Effective Time, with respect to such Company Shares except to surrender such
Certificates in exchange for cash pursuant to this Agreement or to perfect any
rights to receive fair value as a holder of Dissenting Shares that such holders
may have pursuant to the Pennsylvania BCL. Any portion of the Merger
Consideration that remains unclaimed by the shareholders of the Company for one
year after the Effective Time shall be paid to and shall become the property of
Vulcan. Notwithstanding anything to the contrary in this Section 1.1, neither
Vulcan nor the Surviving Corporation shall be liable to a holder of a
Certificate formerly representing Company Shares for any amount properly
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.

                  1.2      Effect of Merger; Tax Status of Merger. The Merger
shall have the effects set forth in Section 1929 of the Pennsylvania BCL.
Without limiting the generality of the foregoing, immediately after the Merger
the Surviving Corporation shall possess all of the rights, privileges, powers
and franchises of each of the Company and Merger Sub, and all property and other
interests due or belonging to the Company and Merger Sub shall be vested in the
Surviving Corporation. It is the intent of the parties hereto that the Merger
will be consummated in accordance with the applicable provisions of the
Pennsylvania BCL. It shall not be a condition to the consummation of the Merger
that any party shall have received a ruling of the Internal Revenue Service or
an opinion of tax counsel as to the federal income tax consequences of the
Merger.

                  1.3      Closing. The consummation of the Merger as provided
herein shall take place at the offices of Womble Carlyle Sandridge & Rice, PLLC,
Suite 700, 1275 Peachtree Street, N.E., Atlanta, Georgia 30309, on the next
business day following the fulfillment of the conditions to Closing set forth in
Section 5 and Section 6 hereof, but not later than April 16, 1997, at 10:00 A.M.

prospects of the Company, financial or otherwise. A true, correct and complete

instruments and agreements to be entered into pursuant hereto and thereto by it,

the Company, enforceable by the Company, and each of the Material Agreements is
enforceable against the Company in accordance with its terms, except as affected
by equitable principles or the exercise of judicial discretion. The execution
and delivery of this Agreement by the Company does not, and the consummation of
the Merger and the other transactions contemplated hereby and thereby will not,
violate or constitute an occurrence of default under any Material Agreement ,

condition or prospects of the Company, financial or otherwise.

Hayes, implemented applicable procedures and activities, or ceased applicable
activities, as appropriate, in order to complete the orderly cessation of all of
the Company's manufacturing of modems and other business which it carries on in
its existing Company facilities and locations ("Shut Down"). In proceeding with
the Shut Down, the Company has and shall use its good faith best efforts to
accomplish so much of the Shut Down matters as requested by Hayes which are
appropriate to be accomplished or commenced prior to the Closing and shall use

between the Company and Vulcan dated March 7, 1997 (the "Red Wing Transaction").

party.

for all such costs and expenses and will not be obligated to incur any such
costs or expenses or any other cost or expense or obligation on behalf of Red
Wing Corporation or which inures to the benefit of Red Wing or Vulcan, after the

properties, contracts and agreements of the Company and shall furnish Hayes and
its counsel and representatives with all available information concerning the
affairs of the Company which is reasonably requested or as necessary to allow
Hayes to make the determination that the condition set forth in Sections 6.1 and
6.3 have been satisfied.

                   7.5     Delivery of Interim Financial Statements. Prior to
Closing, the Company shall promptly deliver to Hayes all regularly prepared
unaudited financial statements of the Company, in format historically utilized
internally, as soon as available.

                   7.6     Notification of Certain Matters. Promptly after
receipt of notice thereof, each of the Company, Hayes, and Vulcan shall advise
the other parties hereto of (i) the occurrence or failure to occur of any event,
the occurrence or failure of which is reasonably believed by such party to cause
any representation or warranty of such party contained in this Agreement to be
untrue or inaccurate in any material respect any time from the date hereof
through the Closing Date; and (ii) any material failure of such party to comply
with or satisfy any covenant or condition to be complied with or satisfied by
him or it hereunder prior to the Closing; and such party shall use his or its
commercially reasonably efforts to remedy the same.

                   7.7     Best Efforts. The Company, Hayes and Vulcan agree to
use their best efforts to fulfill, prior to or at Closing, all conditions to
Closing which are to be fulfilled by them.

                   7.8     Capitalization of Subsidiaries. Hayes shall have duly
formed and capitalized Merger Sub in the amount and as specified in Section
1.1(f) hereof.

                   7.9     Vulcan Shares. At the Closing, Vulcan shall transmit
all of its capital stock of the Company pursuant to the terms and provisions of
the Merger as described in Section 1.1 hereof, and shall cooperate and assist in
authorizing and causing the Merger to occur.

                  7.10     State Taxes. The parties acknowledge that the Company
shall recognize a significant taxable gain in respect of the Red Wing
Transaction which, if not offset by losses recognized prior to the Effective
Time, will result in a Pennsylvania state income tax liability, and a U.S.
Federal Alternative Minimum Tax ("AMT") liability, to be paid by the Company
after the Closing. The Company has cooperated with Hayes prior to the Closing in
accelerating the recognition of losses and taking such other actions as Hayes
has reasonably requested to minimize the Company's Pennsylvania state income and
AMT tax liability.

                  7.11     Release of Letters of Credit. Hayes hereby covenants
and agrees to obtain the release of that certain Standby Letter of Credit issued
by Vulcan in the amount of $1,800,000 in favor of Amplicon, Inc. no later than
October 17, 1997, and to obtain the release of that certain Standby Letter of
Credit issued by Vulcan in the amount of $480,000 in favor of Tokai

                                       27

Financial Services, Inc. within sixty (60) days after the Closing Date. In
addition, Hayes agrees to establish a depository account within ten (10) days
after the Closing Date with a financial institution acceptable to Vulcan (the
"Depository") and to deposit with such Depository a sum equal to two (2) months
rental payment under the Company's Lease Agreement with Amplicon, Inc. dated
October 8, 1994 (the "Amplicon Lease") and to maintain such amount on deposit
with the Depository at all times until the release of Vulcan's Standby Letter of
Credit in favor of Amplicon, Inc. has been obtained. The Depository shall
directly pay to Amplicon from the funds on deposit by Hayes, each monthly
installment under the Amplicon Lease on or before the due date thereof. The
Depository will further agree to notify Vulcan in writing in the event that the
amount of funds on deposit by Hayes is less than the two (2) months rental
amount as specified above. In such event, Vulcan will have the right to make any
payment under the Amplicon Lease directly to Amplicon or to deposit sufficient
funds with the Depository for payment of the Amplicon Lease, and such amount
will be repaid to Vulcan as provided in the Cross Guarantee contemplated by
Section 5.9 hereof.

         8.       Indemnification.

                  8.1      First Indemnification by Vulcan. Subject to the 
matters described in Sections 8.5, 8.6 and 8.7, and effective at the Effective
Time, Vulcan hereby agrees to defend, indemnify and hold harmless (the "First
Vulcan Indemnity") Hayes and its successors, assigns and affiliates and the
Surviving Corporation (collectively, the "Hayes Indemnitees") from and against
any and all losses, deficiencies, liabilities, damages, assessments, judgments,
costs and expenses, including attorneys' fees (both those incurred in connection
with the defense or prosecution of the indemnifiable claim and those incurred in
connection with the enforcement of this provision) (collectively, "Hayes
Losses"), which for purposes of this first Vulcan Indemnity are caused by,
result from or arise out of:

                           (a)      (i) breaches of any representation or
warranty on the part of the Company herein or any Schedule or Exhibit hereto or
in any other written statement, certificate or other instrument delivered by it
pursuant hereto; and (ii) failures by the Company to perform or otherwise
fulfill any of its undertakings or other agreements pursuant to the transactions
or obligations hereunder;

                           (b)      (i) breaches of any representation or
warranty on the part of Vulcan herein or in any Schedule or Exhibit hereto or in
any other written statement, certificate or other instrument delivered by Vulcan
pursuant hereto, except those specific representations listed in Section 8.2(c)
which are covered by the Second Vulcan Indemnity below; and (ii) failures by
Vulcan to perform or otherwise fulfill any of its undertakings or other
agreements or obligations hereunder; or

                           (c)      any and all actions, suits, proceedings,
claims or demands incident to any of the foregoing or such indemnification.

                  8.2      Second Indemnification by Vulcan. Subject to matters
described in Sections 8.5, 8.6(b)-(d) and 8.7, and effective at the Effective
Time, Vulcan hereby agrees to defend, indemnify and hold harmless (the "Second
Vulcan Indemnity") each Hayes Indemnitee from and against any and all Hayes
Losses, and which, for purposes of this Second Vulcan Indemnity, are caused by,
result from or arise out of:

                           (a)      the conduct of Vulcan, Vulcan's affiliates,
the Company or any of their directors or officers, or otherwise arising in any
manner and is the subject of a claim by any shareholder of the Company who was a
shareholder at any time prior to the Effective Time of the Merger ("Prior
Company Shareholders") in connection with the Merger or the Red Wing Transaction
(specifically including, but not limited to claims by any Prior Company
Shareholder for "Fair Value" pursuant to "Dissenters' Rights" under applicable
Pennsylvania law, breach of fiduciary obligations by the Company, Vulcan or any
directors or officers thereof in connection with the Red Wing Transaction or the
Merger, and the disbursement of the Merger Consideration pursuant to Section
1.1(h) hereof);

                           (b)      any failure by Red Wing Corporation to honor
its obligations set forth in Section 5.5 of the Contract Assignment and Asset
Purchase Agreement dated March 7, 1997;

                           (c)      breaches of any representation or warranty
on the part of Vulcan or the Company contained in Sections 2.2(a), 2.2(d), 2.15,
3.1 or 3.6 hereof;

                           (d)      the exercise of any stock options of the
Company which are outstanding at the Effective Time or the conversion of such
options into the right to receive the Merger Consideration Per Share as provided
in Section 1.1(c) hereof; provided that the amount of Vulcan's indemnification
obligation pursuant to this Section 8.2(d) shall be reduced by the amount of the
net cash received by the Company from the exercise of any such stock options;

                           (e)      any default or breach, whether now existing
or hereafter arising under any contract, agreement or obligation assigned by the
Company to and assumed by Red Wing Corporation; or

                           (f)      any and all actions, suits, proceedings,
claims, or demands, incident to any of the foregoing or such indemnification.

                  8.3      Indemnification by the Company. Subject to matters
described in Sections 8.5, 8.6(b)-(d) and 8.7, the Company hereby agrees to
defend, indemnify and hold harmless each Hayes Indemnitee from and against any
and all Hayes Losses (but only if the Merger does not occur), caused by,
resulting from or arising out of:

                           (a)      (i) breaches of any representation or
warranty on the part of the Company herein or in any Schedule or Exhibit hereto
or in any other written statement, certificate or other instrument delivered by
the Company pursuant hereto; and (ii) failures by the Company

                                       29


<PAGE>   30



to perform or otherwise fulfill any of its undertakings or other agreements or
obligations hereunder;

                           (b)      any and all actions, suits, proceedings,
claims or demands, incident to any of the foregoing or such indemnification.

                  8.4      Indemnification by Hayes. Subject to the matters
described in Sections 8.6(b)-(d) and 8.7, Hayes hereby agrees to defend,
indemnify and hold harmless the Company and its successors, assigns and
affiliates (but only if the Merger does not occur) and effective at the
Effective Time, Vulcan and its successors, assigns and affiliates (collectively,
the "Company Indemnitees") from and against any and all losses, deficiencies,
liabilities, damages, assessments, judgments, costs and expenses, including
reasonable attorneys' fees (both those incurred in connection with the defense
or prosecution of the indemnifiable claim and those incurred in connection with
the enforcement of this provision) (collectively, "Company Losses"), caused by,
resulting from or arising out of:

                           (a)      (i) breaches of any representation or
warranty on the part of Hayes herein or in any Schedule or Exhibit hereto or in
any other written statement, certificate or other instrument delivered by Hayes
pursuant hereto; and (ii) failures by Hayes to perform or otherwise fulfill any
of its undertakings or other agreements or obligations hereunder; or

                           (b)      any and all actions, suits, proceedings,
claims or demands incident to any of the foregoing or such indemnification;

                  provided, however, that if any claim, liability, demand,
assessment, action, suit or proceeding shall be asserted by a third party naming
a Company Indemnitee in respect of which a Company Indemnitee proposes to demand
indemnification from Hayes (a "Third Party Company Indemnified Claim"), such
Company Indemnitee shall notify Hayes thereof, provided further, however, that
the failure to so notify Hayes shall not reduce or affect the obligations of
such claimant with respect thereto except to the extent that Hayes is materially
prejudiced thereby. Subject to Section 8.7 of this Agreement and to rights of or
duties to any insurer or other third person having liability therefor, Hayes
shall have the right promptly upon receipt of such notice to assume the control
and defense of, and to compromise or settle, any such Third Party Company
Indemnified Claims; provided, however, that Hayes may not compromise or settle
any such claim without Vulcan's written consent (which consent shall not be
unreasonably withheld) if such settlement does not provide all Company
Indemnitees with a complete release by the claimant and such settlement seeks to
bind Vulcan to any nonmonetary obligation. Vulcan shall be entitled to
participate in the defense of any such claim at its own expense.

                  8.5      Third Party Claims. If any claim, liability, demand,
assessment, action, suit or proceeding shall be asserted by a third party naming
a Hayes Indemnitee or the Company as a party to an action or otherwise making a
claim or seeking recovery from a Hayes Indemnitee in respect of which a Hayes
Indemnitee proposes to demand indemnification (a "Third Party Hayes Indemnified
Claim") pursuant to the First and the Second Vulcan Indemnity, such Hayes

                                       30


<PAGE>   31



Indemnitee shall notify Vulcan (or the Company, as appropriate), provided,
however, that the failure to so notify Vulcan (or the Company, as the case may
be), except with respect to the time limitation described in Section 8.6(b),
shall not reduce or affect the obligations herein with respect thereto except to
the extent that Vulcan is materially prejudiced thereby. Subject to Section 8.7
of this Agreement and to rights of or duties to any insurer or other third
person having liability therefor, Vulcan (or the Company, as the case may be)
shall have the right promptly upon receipt of such notice to assume the control
and defense of, and to compromise or settle, any such Third Party Hayes
Indemnified Claims; provided that Vulcan (or the Company, as the case may be)
may not compromise or settle any such claim without Hayes' written consent
(which consent shall not be unreasonably withheld) if such settlement does not
provide all Hayes Indemnitees with a complete release by the claimant; and
either: (i) it would exceed the amount of the limitations on Vulcan's
indemnification obligation set forth in Section 8.7 (ii) or such settlement
seeks to bind Hayes and/or the Company to any nonmonetary obligation. Hayes
shall be entitled to participate in the defense of any such claim at its own
expense.

                   8.6     Certain Limitations.

                           (a)      The obligations of Vulcan to indemnify
pursuant to the First Vulcan Indemnity pursuant to Section 8.1 of this Article
shall accrue only if the aggregate Hayes Losses for all matters indemnifiable
under Section 8.1 exceed One Hundred Thousand Dollars (US $100,000), and then
Vulcan shall be liable only for Hayes Losses in excess of such amount, subject
to the maximum amount described below. The obligations of Vulcan to indemnify
the Hayes Indemnitees under Section 8,1 shall not exceed the aggregate of Two
Million Five Hundred Thousand U.S. Dollars (US $2,500,000). The limitations
described in this Section 8.6(a) shall not apply to the Second Vulcan Indemnity
as described in Section 8.2.

                           (b)      No claim for indemnification pursuant to
Section 8.1, 8.2, 8.3 or 8.4 may be made unless written notice of such claim,
accompanied by a description of the particular facts involved and the provisions
of this Agreement implicated, is delivered to the indemnifying party
("Indemnification Notice"). For purposes of the First Vulcan Indemnity pursuant
to Section 8.1, the Indemnification Notice must be received on or before
eighteen (18) months from the Effective Time; provided, however, no 18 month
time limit shall apply to indemnification claims pursuant to Indemnification
Notices provided to the indemnifying party before the expiration of such 18
month period where such claim(s) shall not have been fully resolved by such
expiration date; and provided further, no such term limit shall apply with
respect to the indemnification provided pursuant to Sections 8.2, 8.3 or 8.4.

                           (c)      The amount of Vulcan's indemnification
obligation in respect of any Hayes Loss shall be reduced by the amount of any
insurance proceeds received by Hayes, the Company or the Surviving Corporation
in respect of such Loss.

                           (d)      The amount of Vulcan's indemnification 
obligation hereunder shall be reduced by the amount determined to be owing to
Vulcan by Hayes pursuant to Section 9.12 of that certain Preferred Stock
Purchase Agreement of even date herewith.

                                       31


<PAGE>   32



                  8.7      Defense of Certain Claims. In any Third Party Hayes
Indemnified Claims or any Third Party Company Indemnified Claims defended by the
Company, Hayes or Vulcan pursuant to this Agreement (i) the party not
controlling the defense of such claim shall have the right to be represented by
counsel and accountants, at such party's own expense, (ii) the party controlling
the defense of such claim shall keep the other party fully informed of the
status of such claim at all stages thereof, whether or not such other party is
represented by its own counsel, (iii) the Company, Hayes or Vulcan, as
applicable, shall make available to the indemnifying party and its accountants
and legal representatives all books and records of the Company, Hayes or Vulcan
relating to such Third Party Hayes Indemnified Claims or Third Party Company
Indemnified Claims, as applicable, and (iv) the parties shall render to each
other such assistance as may reasonably be requested in order to insure the
proper and adequate defense of such Third Party Hayes Indemnified Claims, as
applicable.

                  8.8      No Impairment of Investors' Rights. Neither the
examination or inspection by audit of the properties, financial condition or
other matters of the Company or its business prior to the Closing, nor the fact
that the Company itself is providing representations, warranties, schedules,
exhibits and entering into the covenants and other matters pursuant to this
Agreement, shall in no way limit, affect or impair the ability of Hayes or the
Company to rely upon the representations, warranties, covenants and obligations
of the Company and Vulcan set forth in this Agreement or otherwise limit the
indemnification obligations set forth in this Article 8.

         9.       Termination. This Agreement may be terminated and the Merger
abandoned at any time prior to the Effective Time:

                           (a)      by mutual written consent of Hayes, Merger
Sub, Vulcan and the Company;

                           (b)      by either Hayes or the Company if the Merger
shall not have been consummated before April 16, 1997 (unless the failure to do
so consummate the Merger by such date shall be due to the action or failure to
act of the party seeking to terminate this Agreement;

                           (c)      by either Hayes or the Company if any
governmental entity shall have issued a final permanent order, decree or ruling
or taken any other final action restraining, enjoining or otherwise prohibiting
the Merger and such order, decree, ruling or other action is or shall become
nonappealable;

                           (d)      by Hayes and Merger Sub, if (i) there shall
have been a breach on the part of the Company or Vulcan of any representation or
warranty of the Company or of Vulcan set forth herein, or (ii) there shall have
been any failure of the Company or Vulcan to perform or comply with the
covenants or agreements hereunder and in either case, the aggregate effect of
all such breaches or failures, as the case may be, would be material; or

                           (e)      by the Company if (i) there shall have been
a breach of any representation or warranty on the part of Hayes or Merger Sub or
(ii) there shall have been a

                                       32


<PAGE>   33



failure of Hayes or Merger Sub to perform or comply its covenants and agreements
hereunder and, in either case, the aggregate effect of all such breaches and
failures would be material.

                  9.2      Effect of Termination. In the event of the
termination and abandonment of this Agreement pursuant to Section 9.1, this
Agreement shall forthwith become void and have no effect, without any liability
on the part of any party hereto or its affiliates, directors, officers or
stockholders. Nothing contained in this Section 9.2 shall relieve any party from
liability for any breach of this Agreement.

         10.      Miscellaneous.

                  10.1     Survival of Warranties. The warranties and
representations of the Company, Hayes, and Vulcan contained in or made pursuant
to this Agreement shall survive the execution and delivery of this Agreement.

                  10.2     Successors and Assigns. The terms and conditions of
this Agreement shall inure to the benefit of and be binding upon the respective
successors and permitted assigns of the parties. Nothing in this Agreement,
express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and permitted assigns any rights,
remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement. The rights and obligations of
the parties hereto may not be assigned without the express written consent of
the other parties hereto; provided, however, that no assignment shall relieve
such party from or diminish or affect such party's obligations hereunder, unless
pursuant to written permission from the party or parties to whom said
obligation(s) is/are owed.

                  10.3     Governing Law; Dispute Resolutions. This Agreement
shall be governed by and construed under the laws of the Commonwealth of
Pennsylvania without reference to its conflicts of law principles.

                           (a)      Policy - Mediation.  The parties hope there
will be no disputes arising out of their relationship. To that end, each commits
to cooperate in good faith and to deal fairly in performing its duties under
this agreement in order to accomplish their mutual objectives and avoid
disputes. But if a dispute arises, the parties agree to resolve all disputes,
except as set forth below, by the following alternate dispute resolution
process:

                                    (i)     first, the parties will seek a fair
                                            and prompt negotiated resolution in
                                            accordance with the following
                                            procedures:

                                            (A)      Upon the written request of
                                                     either party hereto, each
                                                     of the parties will appoint
                                                     a designated representative
                                                     whose task it will be to
                                                     meet for the purpose of
                                                     endeavoring to resolve such
                                                     dispute.

                                            (B)      The designated
                                                     representatives shall meet
                                                     as often as necessary to
                                                     gather and furnish to the
                                                     other all information with
                                                     respect to the matter in
                                                     issue which is appropriate
                                                     and germane in connection
                                                     with its resolution.

                                            (C)      Such representatives shall
                                                     discuss the problem and
                                                     negotiate in good faith in
                                                     an effort to resolve the
                                                     dispute without the
                                                     necessity of any formal
                                                     proceeding relating
                                                     thereto.

                                            (D)      During the course of such
                                                     negotiations all reasonable

                                                     reasonably related to this
                                                     Agreement, will be honored
                                                     in order that each of the
                                                     parties may be fully
                                                     advised of the other's
                                                     position.

                                            (E)      The specific format for
                                                     such discussions will be
                                                     left to the discretion of
                                                     the designated
                                                     representatives, but may
                                                     include the preparation of
                                                     agreed upon statements of
                                                     fact or written statements
                                                     of position furnished to
                                                     the other party.

                                    (ii)    If the designated representatives
                                            cannot resolve the dispute within 
                                            sixty (60) days after the initial
                                            request to negotiate the dispute, 
                                            then the dispute shall be escalated 
                                            to the Chairman of Hayes, or his 
                                            designee, and the Chief Executive 
                                            Officer of Vulcan, for their review
                                            and resolution. If the dispute 
                                            cannot be resolved within thirty
                                            (30) days after referral to such 
                                            officers, then the provisions of 
                                            Subsection (b) below shall apply.

                           (b)      Arbitration.  Except as provided below, all
disputes not resolved in accordance with the above procedures shall be resolved
by binding arbitration. The parties recognize that negotiation or mediation may
not be appropriate to resolve some disputes and agree that either party may
proceed with arbitration without negotiating or mediating. The parties confirm
that by agreeing to this alternate dispute resolution process, they intend to
give up their right to have any dispute decided in court by a judge or jury.
Notwithstanding the foregoing or anything to the contrary herein, if a dispute
arises out of or relates to a breach of the Confidentiality Agreements between
the parties dated February 19, 1997 (between the Company and Hayes) or dated
March 20, 1997 (between Vulcan and Hayes), or any other agreement or provision
for which a party is seeking injunctive relief, then such dispute shall not be
subject to the provisions of this Section 10.3 and may be resolved by formal
judicial or equitable resolution.

                           (c)      Binding Arbitration.  Except as provided
above, any claim between the parties, including but not limited to those arising
out of or relating to this agreement and any claim based on or arising from an
alleged tort, shall be determined by arbitration in Atlanta, Georgia. In any
arbitration proceeding, there shall be three (3) arbitrators, one selected by
Hayes, one selected by Vulcan, and the third selected by the two arbitrators
chosen by the parties. If the parties (or their respective arbitrators) cannot
agree on the identity of the arbitrator(s) within ten (10) days of the
arbitration demand, the arbitrator(s) shall be selected by the administrator of
the American Arbitration Association (AAA) office in Atlanta, Georgia from its
Large, Complex Case Panel (or have similar professional credentials). Each
arbitrator shall be an attorney with at least fifteen (15) years' experience in
commercial law and shall reside in the Atlanta metropolitan area. Whether a
claim is covered by this agreement shall be determined by the arbitrator(s). All
statutes of limitations which would otherwise be applicable shall apply to any
arbitration proceeding hereunder.

                           (d)      Procedures.  The arbitration shall be
conducted in accordance with the AAA Commercial Arbitration Rules with Expedited
Procedures, in effect on the date hereof, as modified by this agreement. There
shall be no dispositive motion practice. As may be shown to be necessary to
ensure a fair hearing: the arbitrator(s) may authorize limited discovery; and
may enter pre-hearing orders regarding (without limitation) scheduling, document
exchange, witness disclosure and issues to be heard. The arbitrator(s) shall not
be bound by the rules of evidence or of civil procedure, but may consider such
writings and oral presentations as reasonable business people would use in the
conduct of their day-to-day affairs, and may require the parties to submit some
or all of their case by written declaration or such other manner of presentation
as the arbitrator(s) may determine to be appropriate. The parties intend to
limit live testimony and cross-examination to the extent necessary to ensure a
fair hearing on material issues.

                           (e)      Hearing - Law - Appeal Limited. The
arbitrator(s) shall take such steps as may be necessary to hold a private
hearing within one hundred twenty (120) days of the initial demand for
arbitration and to conclude the hearing within three (3) days; and the
arbitrator(s)'s written decision shall be made not later than fourteen (14)
calendar days after the hearing. The parties have included these time limits in
order to expedite the proceeding, but they are not jurisdictional, and the
arbitrator(s) may for good cause afford or permit reasonable extensions or
delays, which shall not affect the validity of the award. The written decision
shall contain a brief statement of the claim(s) determined and the award made on
each claim. In making the decision and award, the arbitrator(s) shall apply
applicable substantive law. Absent fraud, collusion or willful misconduct by an
arbitrator, the award shall be final, and judgment may be entered in any court
having jurisdiction thereof. The arbitrator(s) may award injunctive relief or
any other remedy available from a judge, including the joinder of parties or
consolidation of this arbitration with any other involving common issues of law
or fact or which may promote judicial economy, and may award attorneys' fees and
costs to the prevailing party but shall not have the power to award punitive or
exemplary damages. The decision and award of the arbitrators need not be
unanimous; rather, the decision and award of two arbitrators shall be final.

<PAGE>   36



                           (f)      Provisional Remedies.  Pending selection of
the arbitrator(s), either party may request the AAA to appoint unilaterally an
arbitrator for the limited purpose of awarding temporary or preliminary relief.
This award may be immediately entered in any federal or state court having
jurisdiction over the parties even though the decision on the underlying dispute
may still be pending. Once appointed, the arbitrator(s) may, upon request of a
party, issue a superseding order to modify or reverse such temporary or
preliminary relief or may confirm such relief pending a full hearing on the
merits of the underlying dispute. Any such initial or superseding order of
temporary or preliminary relief may be immediately entered in any federal or
state court having jurisdiction over the parties even though the decision on the
underlying dispute may remain pending. Such relief may be granted by the
arbitrator(s) only after notice to and opportunity to be heard by the opposing
party unless the party applying for such relief demonstrates that its purpose
would be rendered futile by giving notice.

                  10.4     Counterparts. This Agreement may be executed in one
or more counterparts, including counterparts transmitted by telecopier or
telefax, all of which shall be considered one and the same agreement. Facsimile
copies with signatures of the parties to this Agreement, or their duly
authorized representatives, shall be legally binding and enforceable. All such
facsimile copies are declared as originals and accordingly admissible in any
jurisdiction or tribunal having jurisdiction over any matter relating to this
Agreement; however, original counterpart signature pages shall be promptly
delivered to all parties and attached to as the counterpart original of the
applicable documents.

                  10.5     Titles and Subtitles. The titles and subtitles used
in this Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

                  10.6     Notices. All notices, requests and other
communications that any party is required or elects to give hereunder shall be
in writing and shall be deemed to have been given (a) upon personal delivery
thereof, including by overnight courier service, one (1) day after delivery to
the courier or, if earlier, upon delivery against a signed receipt therefor or

corporation, setting forth the fact of loss, theft or destruction, and the
Purchaser's or Affiliate's beneficial ownership of the certificate at the time
of such loss, theft or destruction, shall be accepted as satisfactory evidence
thereof, and no indemnity shall be required as a condition to execution and
delivery of a new certificate other than the written agreement of the Purchaser
or such Affiliate, as the case may be, to indemnify the Company and its
directors, officer and agents.

               (c) Any certificate made and delivered in accordance with the
provisions of this Section 9.4 shall be dated as of the date of the certificate
in lieu of which such new certificate is made and delivered. The term
"outstanding", when used in this Agreement with reference to Securities as of
any particular time, shall not include Preferred or Conversion Stock evidenced
by a certificate in lieu of which a new certificate has been made and delivered
by the Company in accordance with the provisions of this Section 9.4, but shall
include such Preferred or Conversion Stock as evidenced by such new certificate.

         9.5   Representations and Warranties to Survive Closing. All

Preferred until the expiration of three (3) years from the date hereof.

         9.6   Severability. The invalidity or unenforceability of any provision
hereof in any jurisdiction shall not affect the validity, legality or
enforceability of the remainder hereof in such jurisdiction or the validity,
legality or enforceability hereof, including any such provision, in any other
jurisdiction, it being intended that all rights and obligations of the parties
hereunder shall be enforceable to the fullest extent permitted by law.

         9.12  Dispute Resolution.

               (a) Policy - Mediation. The parties hope there will be no
disputes arising out of their relationship. To that end, each commits to
cooperate in good faith and to deal fairly in performing its duties under this
agreement in order to accomplish their mutual objectives and avoid disputes. But
if a dispute arises, the parties agree to resolve all disputes, except as set
forth below, by the following alternate dispute resolution process:

                    (i)  first, the parties will seek a fair and prompt
                         negotiated resolution in accordance with the following
                         procedures:

                         (A)   Upon the written request of either party hereto,
                               each of the parties will appoint a designated
                               representative whose task it will be to meet for
                               the purpose of endeavoring to resolve such
                               dispute.

                         (B)   The designated representatives shall meet as
                               often as necessary to gather and furnish to the
                               other all information with respect to the matter
                               in issue which is appropriate and germane in
                               connection with its resolution.

                         (C)   Such representatives shall discuss the problem
                               and negotiate in good faith in an effort to
                               resolve the dispute without the necessity of any
                               formal proceeding relating thereto.

                         (D)   During the course of such negotiations all
                               reasonable requests made by one party to the
                               other for non-privileged information reasonably
                               related to this Agreement, will be honored in
                               order that each of the parties may be fully
                               advised of the other's position.

                         (E)   The specific format for such discussions will be
                               left to the discretion of the designated
                               representatives, but may include the preparation
                               of agreed upon statements of fact or written
                               statements of position furnished to the other
                               party.

<PAGE>   23

                    (ii) If the designated representatives cannot resolve the
                         dispute within sixty (60) days after the initial
                         request to negotiate the dispute, then the dispute
                         shall be escalated to the Chairman of the Company, or
                         his designee, and the Chief Executive Officer of the
                         Purchaser, for their review and resolution. If the
                         dispute cannot be resolved within thirty (30) days
                         after referral to such officers, then the provisions of
                         Subsection (b) below shall apply.

                  (b) Arbitration. Except as provided below, all disputes not
resolved in accordance with the above procedures shall be resolved by binding
arbitration. The parties recognize that negotiation or mediation may not be
appropriate to resolve some disputes and agree that either party may proceed
with arbitration without negotiating or mediating. The parties confirm that by
agreeing to this alternate dispute resolution process, they intend to give up
their right to have any dispute decided in court by a judge or jury.
Notwithstanding the foregoing or anything to the contrary herein, if a dispute
arises out of or relates to a breach of the Confidentiality Agreements between
the parties dated March 20, 1997, or any other agreement or provision for which
a party is seeking injunctive relief, then such dispute shall not be subject to
the provisions of this Section 9.12 and may be resolved by formal judicial or
equitable resolution.

                  (c) Binding Arbitration. Except as provided above, any claim
between the parties, including but not limited to those arising out of or
relating to this agreement and any claim based on or arising from an alleged
tort, shall be determined by arbitration in Atlanta, Georgia. In any arbitration
proceeding, there shall be three (3) arbitrators, one selected by Hayes, one
selected by Vulcan, and the third selected by the two arbitrators chosen by the
parties. If the parties (or their respective arbitrators) cannot agree on the
identity of the arbitrator(s) within ten (10) days of the arbitration demand,
the arbitrator(s) shall be selected by the administrator of the American
Arbitration Association (AAA) office in Atlanta, Georgia from its Large, Complex
Case Panel (or have similar professional credentials). Each arbitrator shall be
an attorney with at least fifteen (15) years' experience in commercial law and
shall reside in the Atlanta metropolitan area. Whether a claim is covered by
this agreement shall be determined by the arbitrator(s). All statutes of
limitations which would otherwise be applicable shall apply to any arbitration
proceeding hereunder.

                  (d) Procedures. The arbitration shall be conducted in
accordance with the AAA Commercial Arbitration Rules with Expedited Procedures,
in effect on the date hereof, as modified by this agreement. There shall be no
dispositive motion practice. As may be shown to be necessary to ensure a fair
hearing: the arbitrator(s) may authorize limited discovery; and may enter
pre-hearing orders regarding (without limitation) scheduling, document exchange,
witness disclosure and issues to be heard. The arbitrator(s) shall not be bound
by the rules of evidence or of civil procedure, but may consider such writings
and oral presentations as reasonable business people would use in the conduct of
their day-to-day affairs, and may require the parties to submit some or all of
their case by written declaration or such other manner of presentation as the
arbitrator(s) may determine to be appropriate. The parties intend to limit live
testimony and cross-examination to the extent necessary to ensure a fair hearing
on material issues.

                                      -19-
<PAGE>   24

                  (e) Hearing - Law - Appeal Limited. The arbitrator(s) shall
take such steps as may be necessary to hold a private hearing within one hundred
twenty (120) days of the initial demand for arbitration and to conclude the
hearing within three (3) days; and the arbitrator(s)'s written decision shall be
made not later than fourteen (14) calendar days after the hearing. The parties
have included these time limits in order to expedite the proceeding, but they
are not jurisdictional, and the arbitrator(s) may for good cause afford or
permit reasonable extensions or delays, which shall not affect the validity of
the award. The written decision shall contain a brief statement of the claim(s)
determined and the award made on each claim. In making the decision and award,
the arbitrator(s) shall apply applicable substantive law. Absent fraud,
collusion or willful misconduct by an arbitrator, the award shall be final, and
judgment may be entered in any court having jurisdiction thereof. The
arbitrator(s) may award injunctive relief or any other remedy available from a
judge, including the joinder of parties or consolidation of this arbitration
with any other involving common issues of law or fact or which may promote
judicial economy, and may award attorneys' fees and costs to the prevailing
party but shall not have the power to award punitive or exemplary damages. The
decision and award of the arbitrators need not be unanimous; rather, the
decision and award of two arbitrators shall be final.

                  (f) Provisional Remedies. Pending selection of the
arbitrator(s), either party may request the AAA to appoint unilaterally an
arbitrator for the limited purpose of awarding temporary or preliminary relief.
This award may be immediately entered in any federal or state court having
jurisdiction over the parties even though the decision on the underlying dispute
may still be pending. Once appointed, the arbitrator(s) may, upon request of a
party, issue a superseding order to modify or reverse such temporary or
preliminary relief or may confirm such relief pending a full hearing on the
merits of the underlying dispute. Any such initial or superseding order of
temporary or preliminary relief may be immediately entered in any federal or
state court having jurisdiction over the parties even though the decision on the
underlying dispute may remain pending. Such relief may be granted by the
arbitrator(s) only after notice to and opportunity to be heard by the opposing
party unless the party applying for such relief demonstrates that its purpose
would be rendered futile by giving notice.
