                                     PART I
 
ITEM 1.  BUSINESS
 
GENERAL DEVELOPMENT
 
     Access Beyond, Inc. (the "Company") is in the business of developing and
marketing products which enable local, remote or mobile users to access network
resources (the "Remote Access Business"). The Company was incorporated on July
23, 1996 and, as described more fully in Note 1 to the Consolidated Financial
Statements, was spun-off from Penril DataComm Networks, Inc. ("Penril") on
November 18, 1996 pursuant to the distribution (the "Distribution") to the
Penril stockholders on such date of shares of the Company's Common Stock. As the
successor company to Penril, the Company retains the historical financial
information of Penril through November 18, 1996 when Penril was merged into Bay
Networks, Inc. ("Bay"). For accounting purposes, the disposition of Penril's
modem business, as a result of the merger agreement with Bay has been accounted
for as a reduction of paid in capital. The Company's product lines consists of
the product line called Access Beyond, serving the remote access market, and
products which serve the LAN and Host Access Markets.
 
     Restructuring:  In the fourth quarter of fiscal 1996, Penril took actions
to strategically restructure its business to reduce costs and improve
competitiveness for the long term. As a result of this plan, Penril recorded a
charge of approximately $9.7 million in the fourth quarter of fiscal 1996. The
restructuring included a plan to focus the Company's business operations on the
remote access server and remote connectivity markets and away from the data
transmission markets. See Note 2 to the Consolidated Financial Statements.
 
     Reduction in Work Force:  In August 1997, the Company completed a reduction
in work force and other cost-saving measures which will result in an annual
savings of approximately $2.0 million and is expected to improve
competitiveness. The cost of such reduction in work force was immaterial.
 
     Acquisitions:  On May 2, 1997, the Company and Paradyne Corporation, a
Delaware corporation ("Paradyne"), entered into the 2290 Remote Access Gateway
("Hawk") Technology Transfer Agreement (the "Technology Agreement") pursuant to
which Paradyne (i) transferred to the Company technology relating to certain
open remote dial access cards (in the form of a comprehensive set of
specifications, technical information, hardware and software) (the "Hawk
Technology"), (ii) sold to the Company certain inventory, tools and equipment
used in the application of the Hawk Technology to develop and manufacture
products, ("Hawk Products") which include the Hawk Technology, (iii) licensed to
the Company certain intellectual property in connection with the Hawk
Technology, and (iv) agreed to provide the Company with technical, engineering,
manufacturing and marketing support, for an aggregate purchase price of 503,704
shares of the Common Stock (the "Paradyne Shares"), and $425,000 in cash. The
Company and Paradyne also entered into a Stock Purchase Agreement, dated as of
May 2, 1997 (the "Purchase Agreement"), pursuant to which the Company sold and
issued the Paradyne Shares to Paradyne. The Company is required to register the
Paradyne Shares for Paradyne under the Securities Act by December 31, 1997 and
use its best efforts to maintain the effectiveness of the Registration
Statement. See Note 7 to the Consolidated Financial Statements.
 
     Pending Transaction.  On July 29, 1997, the Company entered into an
Agreement and Plan of Reorganization (the "Merger Agreement") with Hayes
Microcomputer Products, Inc. ("Hayes"). Under the terms of the Merger Agreement,
Hayes will become a wholly owned subsidiary of the Company and the shareholders
of Hayes at the time the Merger becomes effective will own approximately 79% of
the outstanding equity securities of the Company. The Company will amend its
certificate of incorporation to (i) change its name to Hayes Communications
Inc., (ii) increase the number of authorized shares of capital stock, and (iii)
create Series A Preferred Stock, and the Board of Directors of the Company will
be increased to seven members, five of whom will be designated by the Hayes
shareholders. The Merger Agreement is intended to qualify as a purchase for
accounting and financial reporting purposes. The transaction is subject to
regulatory and the Company's stockholders' approval and certain conditions to
closing as set forth in the Merger Agreement. At the time of the consummation of
the Merger, the Company will be responsible for payment of investment
 
                                        1

] 
banking fees of approximately $1.0 million and for a change of control payment
of $437,500 to Ronald A. Howard, President of the Company. Mr. Howard has
advised the Company that in lieu of receiving such cash payment, he will accept
shares of Common Stock having a value equal to such amount.
 
PRINCIPAL PRODUCTS
 
  Access Beyond Product Line
 
     The Company's Access Beyond product family is targeted at the remote access
market, providing a scalable modular platform combining advanced modem, ISDN
BRI/PRI, remote access, internet working and terminal connectivity capabilities
within a single family of products. The Access Beyond products currently use
three chassis configurations supporting from one to eight interface modules for
end users to choose from, based on current needs and anticipated future growth.
Interface modules are then selected based upon WAN and LAN technology and port
density requirements. The result is a fully integrated solution that effectively
solves the end user's specific remote access needs.
 
     The Access Beyond advanced remote access software delivers complete IP, IPX
and Appletalk routing, remote node and remote control capabilities including
NACS/NASI, all combined with full support for PPP, SLIP, CSLIP, LAT, Telnet, and
a wealth of security and management capabilities. In addition to full support
for SNMP, it provides an advanced, easy to use Windows based management and
configuration utility.
 
     The Company recently introduced a new class of remote access solutions that
integrates both T1 and PRI-ISDN directly within Microsoft Windows NT servers.
This new technology, dubbed "Hawk", supports either digital or analog (modem or
ISDN) remote access transmission and can be easily plugged into any Microsoft
Windows NT(R) or Novell Netware Connect(R) and Border Manager configured server.
Servers can be configured to simultaneously support existing network
applications as well as remote access, with the Dynamic Access Switching
available in the Hawk solution. This substantially reduces network traffic by
connecting users directly into the server hosting the network applications.
 
  LAN and Host Access Products
 
     The LAN and Host Access products currently sold by the Company include
statistical multiplexers and host access servers (VCX), and Ethernet terminal
servers (CSX). Each of the LAN and Host Access products provides the Company
with an existing revenue stream as well as an installed base.
 
     The VCX product line of multiplexers ranges from 4-port remote site
multiplexers to enterprise solutions providing up to 304 ports or 36 trunk lines
and multipurpose communication servers that combine both WAN and LAN
capabilities. These products can function as a data PBX, X.25 PAD, statistical
multiplexer, terminal server or any combination of these. Although the market
for these products is in decline, the Company continues to serve the installed
base and fulfill customer applications.
 
     The CSX Ethernet communications server family provides local and dialup
access to Ethernet LANs. Available as either 8-port or 16-port stand alone units
or as a modular chassis based solution, the CSX server provides terminal and
dialup access for TCP/IP networks.
 
DISCONTINUED OPERATIONS
 
     In fiscal 1995, the Board of Directors of Penril decided to sell
Technipower, Inc. ("TPI"), a subsidiary manufacturing uninterruptible power
supplies and power regulating equipment. In October 1996, the Company completed
the sale of TPI business for $1.6 million in cash and a $2.8 million note. As of
July 31, 1997, a balance of $980,000 remained unpaid on the note which was due
July 31, 1997. The Company reserved the unpaid balance of this note with a
charge of $980,000 to loss on disposal of discontinued operations.
 
     In fiscal 1996, the Board of Directors of Penril decided to sell EMI, a
subsidiary manufacturing test equipment and systems for analysis of
electromagnetic interference and communications security including
 
                                        2
<PAGE>   4
 
applications in satellite communications. In June 1997, the Company completed
the sale of the EMI business to EMI Holding Corp. (the "Borrower"), for $2.0
million in cash, $1.5 million in subordinated term notes, and $500,000 in
warrants. The subordinated term notes include a $1.0 million note with payments
of principal and interest to be made in seven (7) quarterly installments of
$50,000 each, beginning on June 30, 1997, and one final installment together
with accrued interest being due on June 30, 1999. Interest on the $1.0 million
note is at 3% above the highest interest rate being charged to the Borrower by
the Borrower's principal bank lender ("Bank Rate"). The remaining subordinated
term note of $500,000 accrues interest at 2% above the Bank Rate, accruing from
June 30, 1997 and payable in monthly installments beginning on July 1, 1999. The
principal shall be paid in one (1) installment on June 30, 2002. The warrants
are exercisable on June 30, 2002, wherein the Borrower issues to the Company
shares of preferred stock of the Borrower equal to 19.678% of the shares of the
Borrower outstanding immediately after the exercise of these warrants. In
accordance with the Securities and Exchange Commissions Staff Accounting
Bulletin No. 81, "Gain Recognition on the Sale of a Business or Operating Assets
to a Highly Leveraged Entity," a provision was charged to Loss from Disposal of
Discontinued Operations for the outstanding balance of the subordinated term
notes and warrants at July 31, 1997 of $1,950,000. The Company fully expects to
collect these notes and warrants, however the repayments will be recorded as
income when received due to the highly leveraged structure of the Borrower.
 
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. In March 1997, the Company
entered into an agreement (the "Hibbing Agreement") with Hibbing Electronics
Corporation ("Hibbing") pursuant to which Hibbing manufactures and sells printed
circuit card products to the Company. The Hibbing Agreement expires August 31,
1998 at which time Hibbing shall have the option to purchase for nominal
consideration all of the equipment covered under the agreement and the Company
will assign all right, title, and interest in the covered leases and equipment
to Hibbing in exchange for Hibbing's agreement to pay and perform the Company's
obligations under those leases.
 
PATENTS, COPYRIGHTS AND LICENSES
 
     The Company owns, or is licensed or otherwise possesses legally enforceable
rights to use, several patents, patent applications, trademarks, trade names,
service marks, copyrights, schematics, technology, know-how, computer software
programs or applications, and tangible or intangible proprietary information or
material essential and necessary to the business of the Company. The Company may
desire in the future to obtain additional licenses related to its products and
believes, based on industry practice, that any necessary licenses could be
obtained. The costs of such licenses may vary significantly depending on the
nature of the technology involved.
 
     The United States trademarks, trade names and service marks owned by Access
Beyond include ACCESS BEYOND.
 
     The Company may license much of its technology including integrated access
software; CSU/DSU technology; frame relay assembler disassembler technology;
PC/TCP SNMP technology; terminal emulation software; remote access software;
router card technology and software; network management software; and basic
frame relay software for LAN interconnect products.
 
     On June 16, 1996, Penril and Bay entered into a Development and License
Agreement on behalf of Access Beyond whereby Bay licensed to Penril on behalf of
Access Beyond certain intellectual property, software, and technical know-how
related to certain 24-port Digital Modem Cards. The agreement contemplates that
Bay will develop a 24-port Digital Modem Card for Access Beyond, train Access
Beyond's personnel in the underlying technology, and provide technical
assistance where necessary to permit Access Beyond to market this digital
technology.

BACKLOG
 
     A significant portion of data communications revenues are based on customer
purchase orders with immediate shipment requirements. Backlog, which tends not
to be significant in data communications products, is a result of the occasional
customer order with future scheduled shipment requirements or misalignment of
demand and production of a particular product. Because data communications
revenues constitute such a significant portion of the revenues of the Company,
it is the opinion of the Company's management that the dollar amount of backlog
at any given time is not indicative of the actual level of revenues which will
ultimately be realized during future periods. Consequently, the Company's
management believes that the amount of backlog is not a material consideration
in understanding the Company's business operations.
 
COMPETITION
 
     The Company encounters substantial competition in the marketing of its
products and many of its competitors have greater financial, marketing and
technical resources. Important competitive factors in the markets for the
Company's products are established customer base, product performance and
features, service and support as well as price. The Company believes that it
competes favorably with respect to these factors. There can be no assurance that
the Company's products will compete successfully with competitive products that
may be offered in the future or that aggressive pricing will not negatively
impact the profitability of the Company.
 
RESEARCH AND DEVELOPMENT
 
     Under its own sponsorship, the Company is continuously engaged in the
development of new products as well as the development and enhancement of its
existing products. The Company expensed approximately $6.2 million (34% of
consolidated revenues) for product development and engineering during fiscal
1997 compared to $7.4 million (19% of consolidated revenues) in fiscal 1996 and
$7.4 million (14% of consolidated revenues) in fiscal 1995.
 
ENVIRONMENTAL MATTERS
 
     The Company's compliance with federal, state and local environmental laws
had no material effect upon the Company's capital expenditures, earnings or
competitive position.
 
SALES AND MARKETING
 
     The Company's distribution channel is composed of value-added resellers
(VARs), original equipment manufacturers (OEMs) and distributors in more than 40
countries. Sales to end-user customers account for less than 10% of the
Company's revenues. This multi-channel strategy allows the Company to meet
specific customer needs while giving coverage to the worldwide markets.
 
     Value Added Resellers.  VARs integrate the Company's products with products
of other vendors, into networking systems that are sold directly to end-users.
VARs also sell the Company's products as stand-alone units. Sales to VARs are
made at discounts based on purchase volumes and other incentive programs.
 
     Original Equipment Manufacturers.  The Company also customizes its product
for sale through OEMs. This customization may range from simple private labeling
of existing products to complete customization of software and/or hardware to
fit the product lines of the OEM.
 
     Distributors.  The Company also sells its products to distributors who
generally resell to VARs and other dealers. Distributors generally provide a
minimal level of systems integration. The Company offers sales and marketing
programs to assist distributors in promoting, selling and supporting the
Company's products.
 
     Many of the Company's VARs and distributors carry products which are
complementary to, or compete with, those of the Company, and may choose to give
higher priority to products of other suppliers or competitors of the Company.

CUSTOMER SUPPORT, SERVICE AND WARRANTY
 
     The Company services, repairs and provides technical support for its
products. A large portion of these support activities, provided through a 24
hour United States support center, are related to software and hardware
configuration. The Company sells products with end-user warranty periods of up
to sixty months. Following the expiration of the warranty period, if any, the
Company offers services on a time and materials basis, or under maintenance
contracts.
 
EMPLOYEES
 
     The Company had 120 full time employees as of July 31, 1997. The Company
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 who are in great demand. The Company has an employment contract with
Ronald A. Howard, President and CEO, but does not have employment contracts with
its other employees. The Company has experienced no work stoppages and believes
that its employee relations are satisfactory.
 
INTERNATIONAL OPERATIONS
 
     The Company has a subsidiary (Access Beyond, Ltd) located in the United
Kingdom. Financial information about foreign and domestic operations and export
sales is more fully described in Note 10 of the Consolidated Financial
Statements.
 
ITEM 2.  PROPERTIES
 
     The Company's executive offices are located in Gaithersburg, Maryland in
facilities which had previously been leased to Penril. The lease between the
Company and Real Estate Income Partners III was assigned to the Company by
Penril as part of the spin-off, is for 54,874 square feet and expires on
September 30, 1999. The Company has an option to extend the term of the lease
for a period of 119 months and may exercise the option by giving written notice
to the landlord prior to the end of the initial term of the lease. Approximately
50% of the premises is subleased to Hibbing, which pays the Company an amount
equal to 50% of the rent and other charges payable by the Company.
 
     The Company leases a research and development facility in Carlstadt, New
Jersey. The lease is for approximately 44,403 square feet and expires in
September 2001. As more fully described in Note 5 to the Company's Consolidated
Financial Statements, the Company has sublet to other parties a substantial
portion of such premises.
 
     In addition to the facilities mentioned above, the Company and its
subsidiaries lease manufacturing, warehouse and office facilities in
Basingstoke, England. The lease is for approximately 6,800 square feet and
expires in December 2001.
 
     The Company believes its properties are adequate for its needs for the
foreseeable future.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     The Company initiated a lawsuit in December 1994 against Network Systems
Corporation ("NSC") for breach of contract, fraudulent inducement and
defamation. The suit is seeking specific performance, compensatory damages of
$2.0 million and punitive damages of $5.0 million. The litigation arises out of
a contract in which the Company agreed to develop certain computer hardware and
software to NSC's specifications. NSC subsequently brought a counterclaim
alleging negligent misrepresentation, fraud and breach of contract by the
Company. NSC is seeking recision of the contract, restitution of monies paid by
NSC to the Company, compensatory damages of $5.0 million and punitive damages in
an unspecified amount. As of September 23, 1997, the Company was in settlement
discussions with NSC.
 
     In 1993 the Company had initiated a lawsuit against Standard Microsystems
Corp. ("SMC") for breach of contract including failure to transfer technology,
unfair competition and false representations. In September 1996, the Company and
SMC agreed to drop the charges of false representation and settle the
contractual
 
                                        5
<PAGE>   7
 
dispute. In October 1996, the Company received from SMC, in settlement of the
litigation, $3.5 million cash, net of legal payments.
 
     Digital Equipment Corporation ("DEC") has claimed, through a series of
written communications, that the Company has violated DEC patents related to DEC
LAT technology. In August 1997, the Company and DEC entered into a license
agreement including a specific release whereby the Company acquired a
non-exclusive license to develop, manufacture, and market specified products
which are compatible with Digital's LAT technology.
 
     The Company is involved in other routine litigation. Management believes
none of the litigation will have a material adverse effect on the Company's
financial position or results of operations.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
LIQUIDITY AND CAPITAL RESOURCES
 
     In the fourth quarter of fiscal 1996, Penril took actions to strategically
restructure the business to focus on the remote access connectivity products, to
reduce costs and improve competitiveness for the long-term. This restructuring
plan included the elimination of the VCP and BRX product lines and the
introduction of the new remote access product line. As described more fully in
Note 2 to the Company's Consolidated Financial Statements, Penril recorded a
restructuring charge in the fourth quarter of fiscal 1996 of $9.7 million. As of
July 31, 1997, the Company had completed all phases of the restructuring plan
and does not anticipate any additional cost associated with this plan.
 
     In the first quarter of fiscal 1997, prior to the spin-off of the Company,
Penril received approximately $6.1 million from the exercise of employee and
director stock options. The cash generated from these exercises was used for the
expenditures related to the merger and spin-off of the Company. These
expenditures included legal and accounting fees of approximately $700,000,
investment banker fees of $1.6 million, and change of control payments to
certain officers of Penril of $1.8 million. Also in the first quarter of fiscal
1997, prior to the spin-off of the Company, Penril received the following; $3.5
million in cash from Standard Micro Systems Corp. for settlement of the law suit
with Penril, and $1.6 million in cash and $2.8 million in notes from the sale of
its TPI subsidiary. As of July 31, 1997, a balance of $980,000 on the TPI note
was past due. The Company reserved the unpaid balance of this note with a charge
in the fourth quarter of fiscal 1997 of $980,000 to loss on disposal of
discontinued operations.
 
     On November 18, 1996, as a result of the merger between Penril and Bay,
certain assets and liabilities related to the modem business were transferred to
Bay. The assets included $2.5 million in accounts receivables, $2.7 million in
inventory, $1.7 million in deferred tax assets, and $761,000 in other assets.
The liabilities included a $4 million line of credit, $1.5 million in accounts
payables, and $887,000 in other liabilities. All cash and rights to future cash
from the sale of TPI were spun-off to the Company pursuant to the merger
agreement with Bay. In addition, the Company received $1.5 million in cash from
Bay pursuant to the Transitional Services Agreement between Penril and the
Company.
 
     In March 1997, the Company entered into an agreement with Hibbing in which
Hibbing will manufacture and sell printed circuit card products to the Company.
Under the agreement, Hibbing has the right to use the lower level of the
Company's Gaithersburg, Maryland, facility as well as certain equipment needed
for the manufacturing process. Hibbing will pay the Company 50% of the monthly
rent and utilities associated with that facility, and will pay the current
installment amounts on the equipment that the Company leases. This agreement
expires August 31, 1998 at which time Hibbing shall have the option to purchase
all of the equipment covered under the agreement and the Company will assign all
right, title and interest in the covered leases and equipment to Hibbing in
exchange for Hibbing's agreement to pay and perform the Company's obligations
under those leases.
 
     In May 1997, the Company and Paradyne Corporation, a Delaware corporation
("Paradyne"), entered into the 2290 Remote Access Gateway ("Hawk") Technology
Transfer Agreement (the "Technology Agreement") pursuant to which Paradyne (i)
transferred to the Company technology relating to certain open remote dial
access cards (in the form of a comprehensive set of specifications, technical
information, hardware and software)(the "Hawk Technology"), (ii) sold to the
Company certain inventory, tools and equipment used in the application of the
Hawk Technology to develop and manufacture products, ("Hawk Products") which
include the Hawk Technology, (iii) licensed to the Company certain intellectual
property in connection with the Hawk Technology, and (iv) agreed to provide the
Company with technical, engineering, manufactur-
 
                                        8

ing and marketing support, for an aggregate purchase price of 503,704 shares of
the Common Stock (the "Paradyne Shares"), and $425,000 in cash. The Company and
Paradyne also entered into a Stock Purchase Agreement, dated as of May 2, 1997
(the "Purchase Agreement"), pursuant to which the Company sold and issued the
Paradyne Shares to Paradyne. Pursuant to the Purchase Agreement, the Company is
required to register the Paradyne Shares for resale by Paradyne under the
Securities Act.
 
     On June 30, 1997, the Company sold the assets of its EMI subsidiary to a
company principally owned by the former president of EMI and received $2.0
million in cash, $1.5 million in subordinated term notes, and $500,000 in
warrants (repayment terms of the notes and warrants are more fully described in
Note 3 to the Company's Consolidated Financial Statements). In accordance with
the Securities and Exchange Commissions' Staff Accounting Bulletin No. 81, "Gain
Recognition on the Sale of a Business or Operating Assets to a Highly Leveraged
Entity", a provision was charged to Loss from Disposal of Discontinued
Operations for the outstanding balance of the subordinated term notes and
warrants at July 31, 1997 of 2.0 million. The Company fully expects to collect
these notes and warrants, however the repayments will be recorded as income when
received due to the highly leveraged structure of the buyer. The purchase price
was determined by arms-length negotiation.
 
     The cash received from the sources described above was used to fund the
Company's loss from continuing operations for fiscal 1997 of $13.9 million.
Contributing to the Company's cash flow in fiscal 1997 was the reduction of
accounts receivable of $1.4 million (after adjusting for the transfer of
accounts receivable to Bay). This reduction was the result of lower sales
volumes in fiscal 1997 compared to fiscal 1996.
 
     The Company's inventories and accounts payables declined by $600,000 and
$1.1 million respectively (after adjusting for the transfer of inventory and
accounts payable to Bay), as a result of the lower level of business and the
outsourcing of its board level manufacturing to Hibbing Electronics, Inc.
 
     In August 1997, the Company completed a reduction in force of 19 employees
which, in combination with reductions in other expenses, is expected to result
in an annual savings of approximately $2.0 million.
 
     In September 1997, the Company obtained a commitment for a secured working
capital facility of $3.0 million with borrowings based on qualified accounts
receivable and inventory.
 
     The ability of the Company to generate adequate cash for operational and
capital needs is dependent on the success of the Company to increase sales of
its new Access Beyond products including the AB2400/4400 and the "Hawk," coupled
with the collection of cash from notes received in the sale of its TPI and EMI
subsidiaries. In addition it may seek to raise cash from other sources including
sales of securities or other assets of the Company.
 
RESULTS OF OPERATIONS
 
     The Company was incorporated on July 23, 1996, and filed a Form S-1
Registration Statement with the Securities and Exchange Commission which became
effective October 17, 1996. On November 18, 1996 Penril distributed a dividend
to its stockholders of record of one share of common stock of Access Beyond for
each share of Penril common stock held. Penril transferred all of the assets and
liabilities of Penril's remote access business to Access Beyond before becoming
a wholly owned subsidiary of Bay on November 18, 1996. As the successor company
to Penril, the Company retains the historical financial information of Penril
through November 18, 1996, when Penril was merged into Bay. For accounting
purposes, the disposition of the modem business, as a result of the merger
agreement with Bay, has been accounted for as a reduction of paid in capital.
For purposes of this discussion, revenue and expenses that could be specifically
identified with the modem business ("Modem Products") are shown separately from
the Company's Access Beyond and LAN/Host Access Products ("the Company's
Products"). Certain expenses that could not be specifically identified with the
modem business were included with the Company's business, consequently the
expenses reported for the Company's business in fiscal 1996 and 1995 are in
excess of those that would have been incurred had the Company been a stand alone
entity at that time. The results of operations from the discontinued operations
of the EMI and TPI subsidiaries are not included in this discussion. Dollar
amounts are reported in thousands.

</TABLE>
 
     Revenues from the Company's Products declined in fiscal 1997 as a result of
the delay in launching the new Access Beyond products including the AB2400/4400
models. These models were released in the fourth quarter of fiscal 1997. In
addition, there was a continued decline in the market demand for the Company's
CSX terminal servers and VCX multiplexers which represent older technology. The
Company believes that the new Access Beyond products are competitively priced
and will generate revenues over the next fiscal year to offset the decline in
revenues from the older LAN and Host Access products. Revenues from Modem
Products declined because of the sale of the modem product business to Bay in
November 1996.
 
     Exports represented 21% of the Company's total revenues in fiscal 1997 and
32% of the Company's revenues in fiscal 1996. Revenues from the Company's
foreign subsidiary, which is primarily a sales and marketing operation in
England, represented 20% of the Company's total revenues in fiscal 1997 and 19%
of the Company's total revenues in fiscal 1996. The Company does not believe it
has any significant exposure to exchange rate risk.
 
     In the three years ended July 31, 1997, 1996, and 1995, foreign operations
have generated net losses after eliminations of $164,000, $401,000, and $49,000
respectively, while domestic operations generated net losses of $13.7 million,
$20.3 million and $5.1 million respectively. The Company's foreign operation
consists of a sales and distribution facility. The net losses from the Company's
foreign operation is due to greater price competitiveness, which has caused a
decline in gross profit margins. The net losses from the Company's domestic
operations in fiscal 1996 included a restructuring charge of $9.7 million and
merger related expenses of $500,000. The net losses from the Company's domestic
operations in fiscal 1997 and 1996 were due to lower sales volumes and higher
absorption of manufacturing variances and other fixed charges related to the
Company's domestic manufacturing operation. The Company's domestic manufacturing
operation performs all manufacturing for the Company and consequently must
absorb all of the unfavorable manufacturing variances resulting from the lower
sales volumes.

</TABLE>
 
     Gross profit margins for the Company's Products declined slightly in fiscal
1997 because of manufacturing inefficiencies due to lower sales volumes and
because of delays in launching the new Access Beyond product line. Gross profit
margins for Modem Products declined sharply as a result of the sale of the modem
business to Bay and the efforts prior to the closing to reduce inventory of
Modem Products with discounted pricing.

continued development of the new Access Beyond product line including the
AB2400/4400 and the "Hawk" products which were launched in the fourth quarter of
fiscal 1997. Modem Product development expenses declined due to the sale of the
modem business to Bay in November 1996.

     Pursuant to the merger of Penril and Bay in the first quarter of fiscal
1997, Penril incurred merger related expenses of $4.2 million. In the fourth
quarter of fiscal 1997, the Company determined that as a result of the
introduction of its new AB2400/4400 products, an additional reserve for
inventory obsolescence of $864,000 needed to be recorded. Also in the fourth
quarter, the Company recorded a charge to restructuring of $238,000 for
additional inventory that was disposed of as part of the original restructuring
plan. Interest income was generated from the short-term investments that the
Company made in fiscal 1997 with its excess cash. Interest expense resulted from
the Company's capital equipment leases. The decline in interest expense resulted
from the elimination of the line of credit as part of the merger and spin-off
transaction with Bay in fiscal 1997.
 
     In 1993 the Company had initiated a lawsuit against Standard Microsystems
Corp. ("SMC") for breach of contract including failure to transfer technology,
unfair competition and false representations. In September 1996, the Company and
SMC agreed to drop the charges of false representation and settle the
contractual dispute. In October 1996, the Company received from SMC, in
settlement of the litigation, $3.5 million cash, net of legal payments.

     The decrease in revenues for the Company's Products was primarily
attributable to the continued decline in market demand for terminal servers and
multiplexers which resulted in lower volumes and more competitive pricing.

     In the fourth quarter of fiscal 1996, Penril and Bay entered into a License
Agreement whereby Bay acquired a license to certain intellectual property rights
related to Penril's modem technology, and Penril was paid $4.5 million. Revenues
for Modem Products without this license agreement would have been $15.0 million
in fiscal 1996 compared with $19.0 million in fiscal 1995. The decrease in
revenue from the sale of Modem Products was due to slower than expected sales of
Penril's V.34 modems, and a decline in sales of older Modem Products.

      Modem Products..........................................     49%          41%          8%
</TABLE>
 
     The decrease in the gross profit margins for the Company's Products was due
to reductions in product pricing in order to remain competitive in the market
place, and increases in manufacturing inefficiencies due to lower sales volumes.
As noted above, Penril entered into a License Agreement with Bay in the fourth
quarter of fiscal 1996 for $4.5 million. Gross profit margins without this
License Agreement would have been 34% in fiscal 1996 compared to 41% in fiscal
1995. The decrease in gross profit margins for modem products was due to higher
costs of materials in the V.34 modem product line as well as pricing competition
and lower manufacturing efficiencies related to the lower sales volume.

     Selling, general and administrative expenses decreased for the Company's
Products primarily from lower commissions paid due to lower sales volume. There
was also a reduction in personnel costs as a result of eliminating several
administrative positions in Penril's Gaithersburg, Maryland facilities during
fiscal 1995. This reduction was partially offset by a charge of $500,000 during
the fourth quarter of fiscal 1996, for costs incurred related to the Penril/Bay
Merger. All expenses which could not be specifically identified with the modem
products were included with the Company's Products. Consequently the expenses
for the Company's Products are in excess of those that would have been incurred
had the Company been a stand alone company.

     During fiscal 1996, Penril sold Penril Stock in private placements which
generated approximately $14.7 million in cash. A portion of the proceeds was
used to repay all of Penril's term debt during fiscal 1996, which resulted in
decreased interest expense.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Shareholders
Access Beyond, Inc.
Gaithersburg, Maryland
 
     We have audited the accompanying consolidated balance sheets of Access
Beyond, Inc. and subsidiaries (the successor company to Penril DataComm
Networks, Inc.) as of July 31, 1997 and 1996, and the related consolidated
statements of operations, shareholders' equity and cash flows for each of the
three years in the period ended July 31, 1997. These financial statements are
the responsibility of the Company's management. Our responsibility is to
express an opinion on these 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 audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Access Beyond, Inc. and
subsidiaries as of July 31, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended July 31,
1997 in conformity with generally accepted accounting principles.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Effects of the Spin-off and Merger Transactions:  Access Beyond, Inc.
("Access Beyond" or "the Company") was incorporated on July 23, 1996, and filed
a Form S-1 Registration Statement with the Securities and Exchange Commission
which became effective October 17, 1996. On November 18, 1996 Penril DataComm
Networks, Inc. ("Penril") distributed a dividend to its stockholders of record,
one share of common stock of Access Beyond for each share of Penril common stock
held. Penril transferred all of the assets and liabilities of Penril's remote
access business to Access Beyond before becoming a wholly owned subsidiary of
Bay Networks, Inc.("Bay") on November 18, 1996. As the successor company to
Penril, Access Beyond retains the historical financial information of Penril
through November 18, 1996, when Penril was merged into Bay. For accounting
purposes, the disposition of the modem business, as a result of the merger
agreement with Bay, has been accounted for as a reduction of paid in capital.
 
     On November 18, 1996 Penril transferred all of its remote access business
assets and liabilities to Access Beyond as part of its spin-off of Access
Beyond. Assets and liabilities related to the modem business remained with
Penril and Penril became a wholly-owned subsidiary of Bay as part of the Merger
Agreement with Bay. Revenues from the modems prior to the sale of the modem
business to Bay were $4.2 million in fiscal 1997. Under the terms of the Merger
Agreement with Bay, assets and liabilities related to the modem business that
were acquired by Bay included the following at the date of the closing.

     Fair Value of Financial Instruments:  The carrying values of cash and cash
equivalents, accounts receivable, and accounts payable approximate fair value
due to the short maturities of such instruments. Capital lease obligations are
carried at amounts approximating fair values based on current rates offered to
the Company for debt with similar collateral and guarantees, if any, and
maturities.
 
     Inventories:  Inventories are stated at the lower of cost (first-in,
first-out method) or market. The inventories include the cost of material and,
when applicable, labor and manufacturing overhead. During the fourth quarter of
fiscal 1997 as a result of the introduction of the new AB2400/4400 product line,
the Company reviewed its reserve for obsolescence of VCS and CSX product
inventory. Based on this review, the Company recorded a charge of $864,000. The
following table shows the detail in the inventory account for the years ending
July 31, 1997 and 1996.

     Revenue Recognition:  Revenues are recognized at the time of shipment of
the product or performance of product-related services. Revenues from the
license of product technology is recorded upon delivery of the technology
specification and the fulfilment of the other material obligations.
 
     Accounting Estimates:  The preparation of financial statements in
conformity with generally accepted accounting principles (GAAP) requires
management to make estimates and assumptions. These estimates and assumptions
affect the reported amounts of assets and liabilities and the disclosure of
contingent 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 those estimates.
 
     Impairment of Long-Lived Assets:  During fiscal 1996, the Company adopted
the provisions of Statement of Financial Accounting Standards No. 121 (SFAS
121), "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed of", which requires the Company to review long-lived
assets, certain identifiable intangibles, and goodwill related to those assets
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. As a result of events
occurring in the fourth quarter of fiscal 1996, the Company decided to
restructure and refocus its remaining business. Due to these events, the Company
determined that the Excess of Costs over Net

Assets Acquired would not be recoverable, and a charge of $4,952,000 was taken
in the fourth quarter of fiscal 1996 against the carrying value of this asset.
 
     Income Taxes:  Deferred income tax assets and liabilities are computed
annually for differences between the financial statement and tax bases of assets
and liabilities that will result in taxable or deductible amounts in the future.
A valuation allowance is established to reduce deferred tax assets to the amount
expected to be realized.
 
     Earnings Per Share:  Earnings per share for the three years ended July 31,
1997 are calculated based on the weighted average common shares outstanding.
 
     Software Development Costs:  Certain acquired software development costs
are being amortized over their estimated economic life, principally five years,
commencing when each product is available for general release. Internal software
development are expensed as incurred, except those costs applicable to third
party contracts.
 
     Stock-Based Compensation:  Effective August 1, 1996, the Company adopted
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation." The Company has elected to continue to account for stock-based
compensation in accordance with Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees." Accordingly, pro forma net income
and earnings per share information has been presented in Note 7 as required
under SFAS 123.
 
     Related Party Transactions:  As described in Note 5, the Company entered
into a consulting agreement with Henry Epstein, the former CEO of Penril.
 
     In November 1996, John Howard was appointed as a member of the Board of
Directors of the Company. Mr. Howard is the brother of Ronald A. Howard,
President and CEO of the Company.
 
     Concentration of Risk:  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 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.
 
     New Accounting Pronouncements:  During fiscal 1997, the Financial
Accounting Standards Board issued Statements of Financial Accounting Standards
No. 128, 129, 130, and 131. These statements establish standards for computing
and presenting earnings per share, disclosing information about an entity's
capital structure, reporting and displaying comprehensive income and its
components in financial statements, and reporting information about operating
segments in annual financial statements, respectively. Each of these statements 
are effective for financial statements for periods beginning after December 15, 
1997. The effect of adopting these statements in fiscal 1998 is not deemed to 
be material.
 
     Reclassifications:  Certain reclassifications have been made to prior
period consolidated financial statements to conform to the July 31, 1995
presentation.
 
2.  RESTRUCTURING
 
     In the fourth quarter of fiscal 1996, Penril took actions to strategically
restructure its business to improve Penril's financial performance. The
restructuring included a plan to focus Penril's business operations on the
remote access server and remote connectivity markets ("Remote Access") and away
from the data transmission markets. As a result of this plan Penril recorded a
charge of $9,718,000 in the fourth quarter of fiscal 1996 and the Company
recorded a charge of $238,000 in the fourth quarter of fiscal 1997. These
charges were for the following costs.

                    YEARS ENDED JULY 31, 1997, 1996 AND 1995
 
          a. The excess of costs over the fair value of net assets acquired
     through the Datability, Inc. acquisition in fiscal 1993, was related to
     data transmission techniques and, due to the restructuring plan, has no net
     realizable value. Accordingly the remaining book value of $4,952,000 was
     written off in fiscal 1996.
 
          b. A charge of $2,339,000 was taken for the write-off of inventory and
     fixed assets related to the data transmission business. In fiscal 1997 an
     additional charge of $238,000 was taken for the write-off of inventory
     related to the data transmission business, and substantially all inventory
     related to the data transmission business was disposed of.
 
          c. A charge of $1,012,000 was taken for contractual obligations and
     settlement costs incurred for leased facilities in Carlstadt, New Jersey,
     Hong Kong and Malaysia. Under the restructuring plan the Hong Kong and
     Malaysia facilities were vacated at the end of fiscal 1996, and
     substantially all of the leased space in the Carlstadt, New Jersey facility
     was vacated. As of July 31, 1997 a provision of $300,000 remained for the
     future contractual obligations and settlement costs associated with the
     Carlstadt, New Jersey facility.
 
          d. A charge of $979,000 was taken for computer software related to the
     data transmission business that was capitalized in accordance with FAS86,
     which had no realizable value under the restructuring plan. In fiscal 1997
     the remaining book value of this computer software was written off.
 
          e. A charge of $436,000 was taken for severance costs associated with
     employees terminated in connection with the restructuring plan. All costs
     associated with these terminations were paid in fiscal 1997.
 
3.  DISCONTINUED OPERATIONS
 
     In fiscal 1995, the Board of Directors decided to sell Technipower, Inc.
("TPI"), a subsidiary manufacturing uninterruptible power supplies and power
regulating equipment. In October 1996, the Company completed the sale of TPI
business for $1,591,000 in cash and a $2,750,000 note. As of July 31, 1997, a
balance of $980,000 remained unpaid on the note which was due July 31, 1997. The
Company reserved the unpaid balance of this note with a charge of $980,000 to
loss on disposal of discontinued operations.
 
     In fiscal 1996, the Board of Directors decided to sell Electro-Metrics,
Inc. ("EMI"), a subsidiary manufacturing test equipment and systems for analysis
of electromagnetic interference and communications security including
applications in satellite communications. In June 1997, the Company completed
the sale of the EMI business to EMI Holding Corp. (the "Borrower"), for
$2,000,000 in cash, $1,500,000 in subordinated term notes, and $500,000 in
warrants. The subordinated term notes include a $1,000,000 note with payments of
principal and interest to be made in seven (7) quarterly installments of $50,000
each, beginning on June 30, 1997, and one final installment together with
accrued interest being due on June 30, 1999. Interest on the $1,000,000 note is
at 3% above the highest interest rate being charged to the Borrower by the
Borrower's principal bank lender ("Bank Rate"). The remaining subordinated term
note of $500,000 accrues interest at 2% above the Bank Rate, accruing from June
30, 1997 and payable in monthly installments beginning on July 1, 1999. The
principal shall be paid in one (1) installment on June 30, 2002. The warrants
are exercisable on June 30, 2002, wherein the Borrower issues to the Company
shares of preferred stock of the Borrower equal to 19.678% of the shares of the
Borrower outstanding immediately after the exercise of these warrants.
 
     In accordance with the Securities and Exchange Commissions Staff Accounting
Bulletin No. 81, "Gain Recognition on the Sale of a Business or Operating Assets
to a Highly Leveraged Entity", a provision was charged to Loss from Disposal of
Discontinued Operations for the outstanding balance of the subordinated
 
                                       22

term notes and warrants at July 31, 1997 of $1,950,000. The Company fully
expects to collect these notes and warrants, however the repayments will be
recorded as income when received due to the highly leveraged structure of the
Borrower. As a result, the Company recorded a loss on the disposition of the EMI
business of approximately $2.8 million.

7.  COMMITMENTS AND CONTINGENCIES
 
     Pending Transaction:  On July 29, 1997, the Company entered into an
Agreement and Plan of Reorganization (the "Merger Agreement") with Hayes
Microcomputer Products, Inc. Under the terms of the Merger Agreement with Hayes
Microcomputer Products (the "Hayes Merger"), Hayes will become a wholly owned
subsidiary of the Company and the shareholders of Hayes at the time the Merger
becomes effective will own approximately 79% of the outstanding equity
securities of the Company. The Company will amend its certificate of
incorporation to (i) change its name to Hayes Communications Inc., (ii) increase
the number of authorized shares of capital stock, and (iii) create Series A
Preferred Stock, and the Board of Directors of the Company will be increased to
seven members, five of whom will be designated by the Hayes shareholders. The
transaction is subject to regulatory and the Company's stockholders' approval
and certain conditions to closing as set forth in the Hayes Agreement. At the
time of the consummation of the merger, the Company is responsible for payment
of the investment banking fees of approximately $1.0 million and for change of a
control payment of $437,500 to Ronald Howard (president of the Company). Mr.
Howard has advised the Company that in lieu of receiving such cash payment, he
will accept shares of Common Stock having a value equal to such amount.
 
     Possible loss of Hawk Technology:  On May 2, 1997, the Company and Paradyne
Corporation, A Delaware corporation ("Paradyne"), entered into the 2290 Remote
Access Gateway ("Hawk") Technology Transfer Agreement (the "Technology
Agreement") pursuant to which Paradyne (i) transferred to the Company technology
relating to certain open remote dial access cards (in the form of a
comprehensive set of specifications, technical information, hardware and
software)(the "Hawk Technology"), (ii) sold to the Company certain inventory,
tools and equipment used in the application of the Hawk Technology to develop
and manufacture products, ("Hawk Products") which include the Hawk Technology,
(iii) licensed to the Company certain intellectual property in connection with
the Hawk Technology, and (iv) agreed to provide the Company with technical,
engineering, manufacturing and marketing support, for an aggregate purchase
price of 503,704 shares of Common Stock (the "Paradyne Shares"), and
$425,000 in cash. The shares of Common Stock were valued at the fair value at
date of issuance, approximately $1.7 million. The Company and Paradyne also
entered into a Stock Purchase Agreement, dated as of May 2, 1997 (the "Purchase
Agreement"), pursuant to which the Company sold and issued the Paradyne Shares
to Paradyne. Pursuant to the Purchase Agreement, the Company is required to
register the Paradyne Shares for Paradyne under the Securities Act within one
hundred twenty (120) days after the closing, with the right to extend such date
by 60 days, under certain circumstances.
 
     Paradyne's transfer of Hawk Technology, license of Intellectual Property
and, to a certain extent, the inventory of Hawk Product are subject to an
"Unwind" provision in the Technology Agreement. Paradyne may elect to rescind
the Technology Agreement if the Company (a) fails to timely register the
Paradyne Shares or (b) fails to use its best efforts to maintain the
effectiveness of the registration statement, and does not cure such failure
within 30 days after Paradyne gives written notice. Such election would result
in the termination of the license of the Intellectual Property, the transfer of
the Hawk Technology and unsold Hawk Products to Paradyne, and the return to the
Company of the value of the consideration paid, subject to certain adjustments.
 
     Hibbing Agreement:  In March 1997, the Company entered into an agreement
with Hibbing Electronics Corporation in which Hibbing manufactures and sells
printed circuit card products to the Company. Under the Agreement, Hibbing has
the right to use the lower level of the Company's Gaithersburg, Maryland
facility as well as certain equipment needed for the manufacturing process.
Hibbing pays the Company 50% of the monthly rent and utilities associated with
the facility and pays the current installment amounts on the

manufacturing equipment that Hibbing uses and that the Company leases. This
agreement expires August 31, 1998 at which time Hibbing shall have the option to

assign all right, title, and interest in the covered leases and equipment to
Hibbing in exchange for Hibbing's agreement to pay and perform the Company's
obligations under those leases.
 
     Legal Proceedings:  The Company initiated a lawsuit in December 1994
against Network Systems Corporation ("NSC") for breach of contract, fraudulent
inducement and defamation. The suit is seeking specific performance,
compensatory damages of $2,000,000 and punitive damages of $5,000,000. The
litigation arises out of a contract in which the Company agreed to develop
certain computer hardware and software to NSC's specifications. NSC subsequently
brought a counterclaim alleging negligent misrepresentation, fraud and breach of
contract by the Company. NSC is seeking recision of the contract, restitution of
monies paid by NSC to the Company, compensatory damages of $5,000,000 and
punitive damages in an unspecified amount. As of July 31, 1997, the Company was
in discussions with NSC.
 
     In 1993 the Company initiated a lawsuit against Standard Microsystems Corp.
("SMC") for breach of contract including failure to transfer technology, unfair
competition and false representations. In September 1996, the Company and SMC
agreed to drop the charges of false representation and settle the contractual
dispute. In October 1996, the Company received from SMC, in settlement of the
litigation, $3,500,000 cash, net of legal payments.
 
     Digital Equipment Corporation ("DEC") has claimed, through a series of
written communications, that the Company has violated DEC patents related to DEC
LAT technology. In August 1997, the Company and DEC entered into an license
agreement including a specific release whereby the Company acquired a non-
exclusive license to develop, manufacture, and market specified products which
are compatible with Digital's LAT technology.
 
     The Company is involved in other routine litigation.
 
     Management believes none of the litigation will have a material adverse
effect on the Company's financial position or results of operations.

     Change of Control Provision:  In the case of a "change in control" of the
Company, an option holder will generally have the right, commencing at least
five days prior to the "change in control" and subject to any other limitation
on the exercise of the option in effect on the date of exercise, to immediately
exercise any options in full to the extent not previously exercised, without
regard to any vesting limitations.
 
     SFAS No. 123:  For the purposes of following pro forma disclosures required
by SFAS No. 123, the estimated fair value of the options is expensed in the year
that the options are granted using the Black-Scholes option valuation model. The
Black-Scholes model was developed for use in estimating the fair value of traded
options that have no vesting restriction and are fully transferable. In
addition, option valuation models, such as Black-Scholes model, require the
input of highly subjective assumptions including the expected stock price
volatility which are subject to change from time to time. For this reason, and
because SFAS No. 123 fair value-based method of accounting has not been applied
to options granted prior to August 1, 1995, the resulting pro forma compensation
costs are not necessarily indicative of costs to be expected in future years.
 
     In preparing the pro forma information, the following assumptions were
made: risk-free weighted average interest rate was 5.5%; volatility factors of
the expected market price of the Company's common stock of 61.12% in fiscal 1997
and 86.2% for Penril's common stock in fiscal 1996, and option lives of less
than 12 months for both years. The following pro forma information has been
prepared as if the Company had accounted for its employee stock options using
the fair value-based method of accounting established by SFAS No. 123.

9.  RETIREMENT AND SAVINGS PLAN
 
     On November 18, 1996, the Company adopted the Penril Retirement and Savings
Plan as part of the Spin-off and Merger transaction with Bay described in Note
1. The Company's Retirement and Savings Plan ("401(k) Plan") is a defined
contribution plan including provisions of section 401(k) of the Internal Revenue
Code. Employees of the Company who have completed 90 days of service
("Participants") are eligible to participate in the 401(k) Plan. The 401(k) Plan
permits, but does not require, the Company to match employee contributions. In
addition, the Company may make discretionary contributions to the 401(k) Plan
which will be allocated to each Participant based on the ratio of such
Participant's eligible compensation to the total of all Participants' eligible
compensation. Amounts contributed by the Company vest as to 30% after 1 year of
eligible service, 60% after 2 years of eligible service and 100% after 3 years
of eligible service. Participants may elect to direct the investment of their
contributions in accordance with the provisions of the 401(k) Plan. The Company
made matching contributions of $46,000 in fiscal 1997 and Penril made matching
contributions of $61,000 and $45,000 during fiscal 1996 and 1995,
respectively. There were no additional Company contributions in any year. The
Company provides no post-employment or post-retirement benefits.

11.  SUBSEQUENT EVENTS
 
     On September 15, 1997, the Company received a commitment from a third party
lending institution approving a working capital facility of $3,000,000 with
borrowing based on qualified accounts receivable. Interest will be one half
percentage point ( 1/2%) above the Reference Rate publicly announced by Norwest
Bank. A fee of 1% of the total line and term loan commitment will be due and
payable at closing and at each annual anniversary date thereafter. The facility
will be for a two year period. In the event of the Hayes Merger, the Company may
prepay the line of credit by providing the lender with sixty days written
notice, and payment of the service charge (a monthly charge equal to the greater
of $2,000 or  1/3% of the average daily outstanding balance on all loans) times
the remaining months of the two year term. In all other cases the prepayment
penalty will be equal to 3% of the total line commitment in the first year and
2% of the line commitment in all subsequent years thereafter.

such as if the same had been originally named as the Commencement Date, and this
Lease shall run for the full Term; provided that any failure to deliver
possession by August 1, 1989, shall not in any other respect affect the validity

Commencement Date, Landlord shall furnish to Tenant a statement showing the
total actual Operating Costs for the calendar year just ended, including such
reasonable detail as may be requested by Tenant. If the amount of estimated
Operating Costs paid by Tenant for such year exceeds the actual Operating Costs
for such year, such excess shall be credited against the next installments of
Tenant's Operating Costs due from Tenant to Landlord hereunder. If the estimated
Operating Costs for such year are less than the actual Operating Costs for such
year, the Tenant shall pay to Landlord, within thirty (30) days of Tenant's
receipt of Landlord's statement, as Additional rent, a sum equal to the
difference between the actual Operating Costs and the estimated Operating Costs
actually paid, provided, however , that the difference due from Tenant and
payable to Landlord shall not exceed Four Thousand Four hundred and No/100
Dollars ($4,400.00). Landlord and Tenant agree that the aggregate Operating
Costs, due and payable by Tenant, will increase three percent (3%) per annum,

<PAGE>   8

the Commencement Date; that is, the aggregate Operating Costs shall be one
hundred three percent (103%) of the total Operating Costs due and payable for
the immediately preceding calendar year. In the event this Lease is terminated,
Landlord shall compute the credit or deficiency up to the date the Lease was
terminated, and the appropriate party shall immediately pay the other party in
accordance with such calculations.

            Upon occupancy of the Premises, Tenant shall deposit the sum of
Sixty-Two Thousand Eight Hundred Thirty and 73/100 Dollars ($62,830.73) with

Term of this Lease expires, or this Lease is otherwise terminated, Landlord
shall be entitled to retain said Last Month's Rent. In the event this Lease
shall be terminated due to Landlord's breach, or for any reason other than
default or breach by Tenant, then to the extent that the Last Month's rent
exceeds the applicable Basic Monthly Rent for the last valid month of the Lease
prior to such termination, such excess shall be promptly returned by Landlord to
Tenant, otherwise Landlord shall retain said Last Month's rent in addition to
the other remedies provided herein and by law. Upon any sale or transfer of its
interest, Landlord shall transfer the Last Month's rent to its successor in
interest with the specific understanding and acknowledgment of said successor
that Tenant shall be duly credited with such Last Month's Rent, and thereupon,
Landlord shall be released from any liability or obligation with respect
thereto.

with loss payable clauses satisfactory to Landlord and in favor of Landlord and
naming Landlord as an additional insured. The liability limits of the
above-described insurance policies shall in no manner limit the liability of
Tenant under the terms of Article 8 below. Not more frequently than every two
(2) years, if, in the opinion of Landlord, the amount of liability insurance
specified in this Article is not adequate, the above-described limits of
coverage shall be reasonably adjusted by Landlord, by written notification to
Tenant.

                  If, on account of the failure of Tenant to comply with the
provisions of this Article, Landlord is deemed a co-insurer by its insurance
carrier, then any loss or damage which Landlord shall sustain by reason thereof
shall be borne by Tenant and shall be immediately paid by Tenant upon receipt of
a bill therefore and evidence of such loss.

                  On or before the Commencement Date and from time to time
thereafter within ten (10) days of Landlord's request therefor, Tenant shall
provide Landlord with a certificate of insurance for each insurance policy
required by this Lease. In the event such certificates of insurance are not
provided to Landlord in a timely manner, Landlord at its sole option, may
declare this Lease in default and exercise any and all of the remedies herein
provided in the event of a default by Tenant, or Landlord may provide in the
event of a default by Tenant, or Landlord may provide the appropriate insurance
coverage set forth hereinabove and charge the cost thereof to the Tenant as
Additional Rent.

<PAGE>   10
                  (ii) Such other insurance as Landlord deems reasonably
necessary in its sole absolute discretion.

                  Such insurance policies shall be issued in the names of
Landlord and Landlord's lender if Landlord's lender so requires, as their
interests appear. The insurance policies shall provide that any proceeds shall
be made payable to Landlord, or to the holders of mortgages or deeds of trust
encumbering Landlord's interest in the Premises, as their interests shall
appear. All insurance premiums for Landlord's insurance shall be included in the
Operating Costs. Such insurance policies may provide for reasonable deductibles.

and against any and all liability, damages, costs, or expenses, including
attorney's fees, arising from any act, omission or negligence of Tenant or its
officers, contractors, licensees, agents, servants, employees, guests, invitees,
or visitors in or about the Premises, or arising from any breach or default
under this Lease by Tenant or arising from any accident, injury or damage,
howsoever, and by whomsoever caused, to any person or property occurring in or
about the Premises, except for any liability imposed upon Landlord in connection
with pre-material problems not caused by Tenant. All property of Tenant kept or
stored on the Premises shall be so kept or stored at the risk of Tenant only,
and Tenant shall hold Landlord harmless from any claims by Tenant's insurance
carriers, unless such damage shall be caused by the negligence of Landlord. None

(iii) all requirements, now in force or which may hereafter be in force, of any
board of fire underwriters or other similar body now or hereafter constituted

of any court of competent jurisdiction or the admission by Tenant in any action
against Tenant, whether Landlord be a party thereto or not, that Tenant has
violated any law, statute, ordinance, governmental rule or regulation or any
requirement, covenant, condition or restriction shall be conclusive of the fact
as between Landlord and Tenant. Tenant agrees to fully indemnify Landlord
against any liability, claims or damages arising as a result of a breach of the
provisions of this Article 9 by Tenant, and against all costs incurred by
Landlord in connection therewith, which indemnity shall survive the expiration

cause or permit any Hazardous Material to be generated, produced, brought upon,
used, stored, treated or disposed of in or about the Premises by Tenant, its
agents, employees, contractors, sublessees or invitees without the prior written
consent of Landlord. Landlord shall be entitled to take into account such other
factors or facts as Landlord may reasonably determine to be relevant in
determining whether to grant or withhold consent to Tenant's proposed activity
with respect to Hazardous Material. In no event, however, shall Landlord be
required to consent to the installation or use of any storage tanks on the
Premises. Notwithstanding any other provisions herein to the contrary, it is
understood and agreed that Tenant shall be allowed to use and store the
following substances on the Premises, such substances being required for the
normal business operation of Tenant, so long as there are no laws, rules,
regulations or requirements prohibiting such use or storage, and provided that
Tenant uses, stores and disposes of said substances all in accordance with all
laws, rules, regulations and requirements pertaining to said substances of any
present or future agency or governmental body having jurisdiction over the use,

to one and one-half (1-1/2) times the estimated cost of such improvements, to
insure Landlord against any liability for mechanic's liens and to insure
completion of the work. Landlord shall have the right at all times to post on
the Premises, any notices permitted or required by law, or that Landlord shall
deem proper, for the protection of Landlord, the Premises, and any other party

otherwise penetrate or mutilate the roof without Landlord's prior written
consent.

      13.   MECHANIC'S LIENS

            Tenant shall keep the Premises free from any liens arising out of
any work performed, material furnished or obligation incurred by or for Tenant
or any person or entity claiming through or under Tenant. In the event that
Tenant shall not, within ten (10) days following the imposition of any such
lien, cause the same to be released of record by payment or posting of a proper
bond, Landlord shall have, in addition to all other remedies provided herein and
by law, the right, but not the obligation, to cause such lien to be released by
such means as Landlord deems proper, including payment of the claim giving rise
to such lien. Al such sums paid and expenses incurred by Landlord in connection
therewith shall be payable to Landlord by Landlord in connection therewith shall
be payable to Landlord by Tenant with interest at the rate of one and one-half
percent (1-1/2%) per month (but not to exceed the maximum legal rate) from the
date of payment and shall be due and payable to Landlord by Tenant on demand.

      14.   ENTRY BY LANDLORD

            Landlord reserves and shall at any reasonable and all times have the
right to enter the Premises, subject to Tenant's reasonable security policies
and procedures to inspect the same, and to determine whether Tenant is complying
with its obligations hereunder, to supply any other service to be provided by
Landlord to Tenant hereunder, to exhibit the Premises to prospective purchasers,
mortgagees or Tenants, to post notices of non-responsibility, and to alter,
improve, or repair the Premises and any portion thereof, without abatement of
rent, and may for that purpose erect scaffolding and other necessary structures
that are reasonably required by the character of the work to be performed by
Landlord, provided that the business of Tenant shall not be interfered with
unreasonably. Tenant hereby waives any claim for damages for any injury of
inconvenience to or interference with Tenant's business, any loss of occupancy
or quiet enjoyment of the Premiss. For each of the aforesaid purposes, Landlord
shall at all times have and retain a key with which to unlock all of the doors
in, upon and about the Premises, excluding Tenant's vaults and safes, and
Landlord shall have the right to use any and all means which Landlord may deem
proper to open such doors in the event of any emergency. Any entry to the
Premises or portions thereof obtained by Landlord by any of said means, or
otherwise, shall not under any circumstances be construed or deemed to be a
forcible or unlawful entry into, or a detainer of, the Premises, or an eviction,
actual or constructive,


                                       14
<PAGE>   16

language to the contrary contained hereinabove, Landlord agrees that Landlord
will, except in the case of emergency, give Tenant twenty-four (24) hours notice
before entering Tenant's Premises and will abide by all reasonable rules and
regulations of Tenant including, but not limited to, the provision that
Landlord, its agents or employees will be escorted by security officers or other
employees of Tenant, wear badges and otherwise comply with the reasonable
request of Tenant relating to the maintenance of security.

      15.   DESTRUCTION

      A.    Minor Insured Damages

            In the event the Premises, or any portion thereof, is damaged or
destroyed by any casualty that is covered by the insurance maintained by
Landlord pursuant to Article 7 above, Landlord shall rebuild and restore the
Premises, and repair the damaged portion thereof, provided that: (i) the amount
of insurance proceeds available to Landlord equal or exceeds the cost of such
rebuilding, restoration and repair; (ii) the damage or destruction has occurred
more than twenty-four (24) months before the expiration of the Term; and (iii)
such rebuilding, restoration or repair is then permitted, under applicable
governmental laws, rules and regulations, to be done in such a manner as to
return the Premises to substantially its condition immediately prior to the
damage or destruction including, without limitation, the same net rentable floor
area. To the extent that insurance proceeds must be paid to a mortgagee or
beneficiary under, or must be applied to reduce any indebtedness secured by, a
mortgage or deed of trust encumbering the Premises, such proceeds, for the
purposes of this Section, shall be deemed not available to Landlord unless such
mortgagee beneficiary permits Landlord to use such proceeds for the rebuilding,
restoration and repair of the Premises. Notwithstanding the foregoing, Landlord
shall have no obligation to repair any damage to, or to replace any of,
Tenant's personal property, furnishings, fixtures, equipment or other such
property or effects of Tenant.

      B.    Major Damage or Uninsured Damage

            In the event the Premises, or any portion thereof, is damaged or
destroyed by any casualty and Landlord is not obligated, under Section A, next
above, to rebuild or restore the Premises or to repair the damaged portion
thereof, then Landlord may, at its option, either: (i) rebuild restore the
Premises and repair the damaged portion thereof; or (ii) terminated this Lease
effective as of the date the damage or destruction occurred. if Landlord does
not give Tenant written notice within thirty (30) days after the damage or
destruction occurs of its election to rebuild or restore the Premises, and
repair the damaged portions thereof, Landlord shall be deemed to have elected to
terminate this Lease.


                                       15
<PAGE>   17
      C.    No Abatement of Rent

            There shall be no abatement of rent by reason of damage to or
destruction of the Premises, or any portion thereof, and this Lease shall
continue in full force and effect after such damage or destruction, except that,
to the extent that either: (i) Landlord receives insurance proceeds for loss of
rental income attributable to the Premises; or (ii) the floor area of the
Premiss cannot be reasonably used by Tenant for conduct of its business, the
Basic Monthly Rental shall abate proportionately according to (i) or (ii) above
commencing thirty (30) days after the damage to or destruction of the Premises,
and except that, if Landlord elects to terminate this Lease as provided in
Section B, next above, no obligation shall accrue under this Lease after such
termination. Notwithstanding the provisions of this Article if any such damage
is due to the fault or neglect of Tenant, any person claiming through or under
Tenant, or any of their employees, suppliers, shippers, customer or invitees,
then there shall be no abatement for rent by reason of such damage, unless
Landlord is reimbursed for such abatement pursuant to any rental insurance
policy that Landlord may, in its sole discretion, elect to carry.

      D.    Termination

            Notwithstanding the above, in the event the Premises are destroyed
by fire or other casualty so as to be more than thirty (30%) percent untenable
and its shall require more than ninety (90) days for the Landlord to commence
restoration of same, then either party hereto, upon written notice to the other
party, which notice shall be given within thirty (30) days after such
destruction, may terminate this Lease, in which case, the rent shall be
apportioned and paid to the date of said fire or casualty.

      16.   DEFAULTS AND REMEDIES

            Provided, and it is hereby mutually covenanted and agreed, that if
Tenant shall fail to keep and perform each and every covenant, condition and
agreement herein contained including, but not limited to, the timely payment of
rent, or if Tenant shall abandon or evidence any intention to abandon the
Premises, or if the Premises shall become vacant or deserted, or if the estate
created shall be taken on executions or other process of law, or if Tenant shall
petition to be declared or shall be declared bankrupt or insolvent according to
law, or if any assignment shall be made of Tenant's property for the benefit of
creditors, then and in each and every such case, from thenceforth and at all
times thereafter, at the sole option of Landlord, Tenant's right of possession
shall thereupon cease and terminate, and Landlord shall be entitled to
possession of the Premises, to remove all persons and property therefrom, and to
re-enter the same without further demand of rent or demand of possession of said
Premises, subject, however, to due process of law, and in the event of such
re-entry or retaking by Landlord, Tenant shall nevertheless remain in all events
liable and answerable for the full rental to the date of retaking or re-entry,
and Tenant shall also be and remain answerable in damages for any and all loss
or damage and for the deficiency or loss of rent which Landlord may thereby
sustain in respect of the balance of the Term; and in such case, Landlord
reserves full power, which is hereby acceded by Tenant, to let the said Premises
for the benefit of Tenant, to let the said


                                       16
<PAGE>   18
Premises for the benefit of Tenant in liquidation and discharge, in whole or in
part, as the case may be, of the liability of Tenant under the terms and
provisions of this Lease; and such damages, at the option of Landlord, may be
recovered by it at the time of the retaking or re-entry, or in separate actions,
from time to time, as Tenant's obligation to pay rent would have accrued if the
Term had continued, or from time to time as said damages shall have been made
more easily ascertainable by relettings of the Premises.

            All rents received by Landlord in any reletting shall be applied:
first, to the payment of such expenses as Landlord may have incurred in
recovering possession of the Premises and in reletting the same; second, to the
payment of any costs and expenses incurred by Landlord either for making
necessary repairs to the Premises or in curing any default on the part of the
Tenant in a covenant or condition herein made binding upon Tenant; and, last,
any remaining rent shall be applied toward the payment of rent due from Tenant
under the terms of this Lease, with interest; and Tenant expressly agrees to pay
any deficiency then remaining. Landlord, however, at its option, may refrain
from terminating Tenant's right of possession, and in such case, may enforce
against Tenant the provisions of this Lease for the full Term hereof; and it is
further provided, that if, under the provisions hereof applicable, summary
process shall be served, and a compromise or settlement therefor shall be made,
it shall not be constituted as a waiver of any breach of any covenant, condition
or agreement as a waiver of any breach of any covenant, condition or agreement
herein contained, shall operate as a waiver of the covenant, condition or
agreement itself, or of any subsequent breach thereof.

            No provision of this Lease shall be deemed to have been waived by
Landlord or Tenant unless such waiver shall be in writing signed by Landlord or
Tenant. No payment by Tenant or receipt by Landlord of the lesser amount than
the monthly installments of rent herein stipulated shall be deemed to be other
than on account of the earliest stipulated rent nor shall any endorsement or
statement on any check or any letter accompanying any check or payment as rent
be deemed an accord and satisfaction, and Landlord may accept such check or
payment without prejudice to Landlord's right to rec over the balance of such
rent or pursue any other remedy provided in this Lease.

      17.   WAIVER OF JURY TRIAL BY TENANT

            Tenant and Landlord waive the right to a jury trial in any suit by
Landlord for possession, or in any other suit or action relating to or arising
from this Lease in which Landlord and Tenant are opposing parties.

      18.   CONDEMNATION

            If the whole of the leased Premises shall be acquired or condemned
by eminent domain for any public or quasi-public use or purpose, then the term
of this Lease shall cease and terminate as of the date of title vesting in the
condemning authority and all rentals shall be paid up


                                       17
<PAGE>   19
to that date, and Tenant shall have no claim against Landlord nor the condemning
authority for the value of any unexpired term of this Lease.

            If any part of the leased Premises shall be acquired or condemned as
aforesaid, and in the event that such partial taking or condemnation shall
render the leased Premises unsuitable of the business of Tenant, then the term
of this Lease shall cease and terminate as of the date of title vesting in such
proceeding. Tenant shall have no claim against Landlord nor the condemning
authority for the value of any unexpired term of this Lease and rent shall be
adjusted to the date of such termination. In the event of a partial taking or
condemnation which is not extensive enough to render the Premises unsuitable for
the business of Tenant, then Landlord shall promptly, at its cost, restore the
Premises to a condition comparable to its condition at the time the Premises
were tendered to Tenant, pursuant to Article 2, less the portion lost in the
taking, except that Landlord shall not be obligated to repair any damage for
which, or restore the Premises to the extent that, Tenant has been reimbursed by
the condemning authority. Thereafter, this Lease shall continue in full force
and effect with rent adjusted pro rata as to the date and portion of the lost
Premises.

            In the event of any condemnation or taking as aforesaid, whether
whole or partial, Tenant shall not be entitled to any part of the award paid for
such condemnation and Landlord is to receive the full amount of such award.

            Tenant shall have the right to claim and recover from the condemning
authority, but not from Landlord, such compensation as may be separately awarded
or recoverable by Tenant in Tenant's own right on account of any and all damages
to Tenant's business by reason of the condemnation and for or on account of any
cost or loss to which Tenant might be put in removing Tenant's merchandise,
furniture, fixtures, leasehold improvements and equipment.

            Landlord may, without any obligation to Tenant, agree to sell and/or
convey to the condemnor the Premises, or any portion thereof, sought by the
condemnor, without first requiring that any action or proceedings be instituted
or, if instituted, pursued to a judgment.

      19.   HOLDING OVER

            Any holding over after the expiration of the Term, with the consent
of the Landlord, shall be construed to be tenancy from month to month at two
hundred percent (200%) of the rent herein specified (prorate on a monthly basis)
unless Landlord shall specify a different lesser rent in its sole discretion,
together with an amount estimated by Landlord for the monthly Operating Costs
payable under this Lease, and shall otherwise be on the terms and conditions
herein specified as far as applicable. Any holding over without Landlord's
consent shall constitute a default by Tenant and shall entitle Landlord to
re-enter the Premises as provided in Article 14 hereof.

of this Lease. Such amounts shall be payable upon demand. In addition, if any

insurance which Tenant should have obtained pursuant to this Lease.

      21.   ASSIGNMENT AND SUBLETTING

      A. Tenant shall not directly or indirectly, voluntarily or by operation of
law, sell, assign, encumber, pledge or otherwise transfer or hypothecate all or
any part of the Premises or Tenants' leasehold estate hereunder (collectively,
"Assignment"), or permit the Premises to be occupied by anyone other than Tenant
or sublet the Premises (collectively, "Sublease") or any portion thereof without
Landlord's prior written consent in each instance, except as provided in Section
B below, however, Landlord shall not unreasonably withhold its consent.

      B. Tenant may assign this Lease or sublease the Premises, without
Landlord's consent, to any corporation which controls, is controlled by or is
under common control with Tenant, or to any corporation resulting from the

Tenant's Affiliate shall assume, in writing, all of Tenant's obligations under
this Lease.

      C. If Tenant desires to assign the Lease or sublease the Premises, Tenant
shall have the right, but not the obligation, to offer, in writing, to terminate
the Lease as of a date specified in the offer. If Landlord elects in writing to
accept the offer to terminate as to the portion of the Premises that Tenant
proposes to assign or sublease within twenty (2) days after notice of the offer,
the Lease shall terminate as of the date specified and all the terms and
provisions of the Lease governing termination shall apply. If Tenant has not
offered to terminate this Lease or if Landlord does not so elect to terminate,
the Lease shall continue in effect until otherwise terminated and the provisions
of Section D with respect to any proposed assignment or sublease shall continue
to apply.

      D. Tenant's request to enter into an Assignment of this Lease or a
Sublease of the Premises or any portion thereof, shall be set forth by written
notice to Landlord, which notice shall contain: (i) the name of the proposes
assignee, subTenant or occupant; (ii) the nature of the proposed assignee's,
subTenant's or occupant's business to be carried on in the Premises; (iii) the
terms and

<PAGE>   21
provisions of the proposed Assignment or Sublease; and (iv) such financial
information as Landlord may reasonably request concerning the proposed assignee,
subTenant or occupant.

      E. At any time within fifteen (15) days after Landlord's receipt of the
notice specified in Section D above, Landlord may by written notice to Tenant
elect to: (i) sublease itself the portion of the Premises specified in Tenant's
notice hereunder, or any portion thereof; (ii) take an assignment of Tenant's
leasehold estate specified in Tenants' notice hereunder, or any portion thereof;
(iii) consent to the Sublease or Assignment; or (iv) disapprove the Sublease or
Assignment, although Landlord will not unreasonably disapprove such Sublease or
Assignment. In the event Landlord elects to sublease or take an assignment from
Tenant as described in subsection (i) and (ii) above, the rent payable by
Landlord shall be ninety-five (95%) percent of the amount Tenant would have
received from a subTenant.


                                       20
<PAGE>   22
of assumption shall not release or discharge the assignee from its liability as
set forth above.

      I. Notwithstanding Section 21.H., should Tenant's DataComm Division be
purchased by another person or entity which desires to become the assignee of
Tenant under this Lease, and should said purchaser have a financial condition
and creditworthiness equal to or greater than that of Tenant at the Commencement
Date, as determined by Landlord in Landlord's sole discretion, then, and only
then, will this be and Assignment of the Lease in which the assignee assumes all
of the rights and obligations of the Lease and Tenant is concurrently released
of all rights and obligations hereunder, effective as of the date of said
Assignment.

      J. Tenant shall pay Landlord's reasonable expenses for each such proposed
transfer to cover the legal review and processing expenses of Landlord, whether
or not Landlord shall grant its consent to such proposed transfers, Assignments
or Sublease.

      22.   MORTGAGE PROTECTION/SUBORDINATION

      A.    Subordination or Superiority of Other Loans

            As to any loan that may be secured on the subject realty of which
the Tenant's Premises are a part, the rights of Tenant under this Lease are and
shall be, at the option of Landlord, either subordinate or superior to any first
mortgage or first deed of trust (including a consolidated mortgage or deed of
trust) constituting a lien on the Premises or Landlord's interest therein or any
part thereof, whether such mortgage or first deed of trust has hereto fore been,
or may hereafter be, placed upon the Premises by Landlord, and to any ground or
master lease if Landlord's title to the Premises or any part thereof is or shall
become a leasehold interest. To further assure the foregoing subordination ro
superiority, Tenant shall, upon Landlord's request, together with the request of
any first mortgagee under a mortgage or beneficiary under a first deed of trust
or ground or master lessor, execute any instrument that does not materially and
adversely affect Tenant's rights or duties under this Lease, or instruments
intended to subordinate this Lease, or at the option of Landlord, to make
superior to any first mortgage, first deed of trust, or ground or master lease.

      B.    Attornment

            Notwithstanding the provisions of Section A, next above, Tenant
agrees: (i) to attorn to any mortgagee of a mortgage or beneficiary of a deed of
trust encumbering the Premises and to any party acquiring title to the Premises
by judicial foreclosure, trustee's sale, or deed in lieu of foreclosure, and to
any ground or master lessor, as the successor to Landlord hereunder; (ii) to
execute any attornment agreement reasonably requested by a mortgagee,
beneficiary, ground or master lessor, or party so acquiring title to the
Premises; and (iii) that this Lease, shall remain in force notwithstanding any
such judicial foreclosure, trustee's sale, deed in lieu of foreclosure, or
merger of titles.

      23.   ESTOPPEL CERTIFICATE/FINANCIAL STATEMENTS/TRANSFER OF
            LANDLORD'S INTEREST

      A.    Estoppel Certificate

            Tenant, at any time and from time to time upon not less than ten
(10) days prior written notice from Landlord, agrees to execute and deliver to
Landlord a statement: (i) certifying that this Lease is unmodified and in full
force and effect, or, if modified, stating the nature of such modification and
certifying that this Lease, as so modified, is in full force and effect and the
date to which the rent and other charges are paid in advance, if any; and (ii)
acknowledging that there are not, to Tenant's knowledge, any uncured defaults on
the part of Landlord hereunder, or specifying such defaults if they are claimed
evidencing the status of this Lease. Tenant's failure to deliver an estoppel
certificate within such time shall be conclusive upon Tenant that: (i) this
Lease is in full force and effect without modification except as may be
represented by Landlord, (ii) to Tenant's knowledge there are not uncured
defaults in Landlord's performance; and (iii) no rent has been paid in advance
except as set forth in this Lease.

      B.     Furnishing of Financial Statements

            Landlord has reviewed financial statements if so requested of Tenant
and has relied upon the truth and accuracy thereof with Tenant's knowledge and
representations of the truth and accuracy of such statements and that said
statements accurately and fairly depict the financial condition of Tenant. Said
financial statements are an inducing factor and consideration for the entering
into of this Lease by Landlord with Tenant. Tenant shall, at any time and from
time to time upon not less than thirty (30) days prior written notice from
Landlord, furnish Landlord with financial statements as are publicly available,
reflecting Tenant's then financial condition.

      C.    Liability of Transferee

            In the event Landlord shall sell or otherwise convey its title to
the Premises, after the effective date of such sale or conveyance Landlord shall
have no further liability under this Lease to Tenant except as matters of
liability which have accrued and are unsatisfied as of the date of sale or
conveyance, and Tenant shall seek performance solely from Landlord's purchaser
or successor in title.

      24.   PARKING

            Tenant agrees to maintain or cause to be maintained the automobile
parking area and to maintain and operate, or cause to be maintained and
operated, said automobile parking area during the Term of this Lease for the
benefit and use of the customers, service suppliers, other invitees and
employees of Tenant. There will be no additional charges for parking. Whenever
the words "automobile" or "parking area" are used in this Lease, it is intended
that the same shall include, whether in a surface parking area or a parking
structure, the automobile parking stalls, driveways,


                                       23
<PAGE>   24
entrances and exist and sidewalks, landscaped area, pedestrian passageways in
conjunction therewith and other areas designed for parking. Tenant shall keep
said automobile parking area in a neat, clean and orderly condition, properly
lighted and landscaped, and shall repair any damages to the facilities thereof.
Nothing contained herein shall be deemed to impose liability upon Landlord for
personal injury or theft, for damage to any motor vehicle, which is suffered by
Tenant or any of its employees, customers, service suppliers or other invitees
in connection with their use of said automobile parking area. Landlord shall
also have the right to establish such reasonable rules and regulations as may be
deemed desirable, at Landlord's sole discretion, for the proper and efficient
operation and maintenance of said automobile parking area. Tenant shall comply
with any such rules and regulations established by Landlord in conjunction
therewith, in its use of said automobile parking area and the use of the same by
Tenant's customers, employees, service suppliers and other invitees. Landlord
shall reasonably cooperate with Tenant in enforcing Tenant's parking rights
against any third parties, which enforcement shall be at Tenant's expense.


      25.   SIGN AND FLAGPOLE

      A.    Sign

                  Tenant shall have the right to install a sign on the exterior
and interior of the Premises indicating the name under which Tenant is
conducting business subject to: (i) governmental regulations; (ii) presentation
to Landlord of a structural report verifying the ability of the Premises to
support such equipment; (iii) providing an indemnification to hold Landlord and
Landlord's agents harmless for any damage resulting from the installation, use
or removal of such equipment; (iv) payment of all costs associated with the
installation, use and removal shall be borne solely by Tenant; (v) the
understanding and agreement that Tenant shall remove such equipment and restore
the condition of the Premises upon Landlord's request at the end of the Term,
within ten (10) days after vacating the Premises. Subject to the foregoing,
Landlord approves Tenant's use of signs as of the Commencement Date of this
Lease.

      B.     Flagpole

                  Tenant shall have the right to install a flagpole on the
exterior of the Premises subject to: (i) governmental regulations; (ii)
providing an indemnification to hold Landlord and Landlord's agents harmless for
any damage resulting from the installation, use or removal of such equipment;
(iii) payment of all costs associated with the installation, use and removal
shall be borne solely by Tenant; (iv) the understanding and agreement that
Tenant shall remove such equipment and restore the condition of the Premises
upon Landlord's request at the end of the Term, within ten (10) days after
vacating the Premises. Subject to the foregoing, Landlord approves Tenant's
installation of a flagpole as of the Commencement Date of this Lease.

      26.    LATE PAYMENTS:  INTEREST AND LATE CHARGES

      A.     Interest

                  Except as otherwise provided herein, any amount due from
Tenant to Landlord which is not paid when due shall bear interest at the maximum
rate permitted by law from the date such payment is due until paid, except that
amount spent by Landlord on behalf of Tenant shall bear interest at such rate
from the date of disbursement by Landlord.

      B.     Late Charges

                  Tenant hereby acknowledges that in addition to lost interest,
the late payment by Tenant to Landlord of rent or any other sums due hereunder
will cause Landlord to incur other costs not contemplated in this Lease, the
exact amount of which will be extremely difficult and impracticable to
ascertain. Such other costs include, but are not limited to, processing,
administrative and accounting costs. Accordingly, if any installment of rent or
any Additional Rent or other sum due from Tenant shall not be received by
Landlord within five (5) days after such amount shall be due, Tenant shall pay
to Landlord a late charge equal to three percent (3%) of such overdue amount,
not to exceed One Thousand and no/100 ($1,000,000). The parties hereby agree
that (i) such late charge represents a fair and reasonable estimate of the costs
Landlord will incur in processing such delinquent payment by Tenant; (ii) such
late charge shall be paid to Landlord as liquidated damages; and (iii) such late
charges and the payment of interest are distinct and separate from one another
in that the payment of interest is to compensate Landlord for the use of
Landlord's money by Tenant, while the payment of late charges is to compensate
Landlord for the additional administrative expense incurred by Landlord in
handling and processing delinquent payments.

      C.    No Waiver

                  Neither assessment nor acceptance of interest or late charges
by Landlord shall constitute a waiver of Tenant's default with respect to such
overdue amount, nor prevent Landlord from exercising any of its other rights or
remedies under this Lease. Nothing contained in this Article shall be deemed to
condone, authorize, sanction or grant to Tenant an option for the late payment
of rent, additional rent or other sums due hereunder and Tenant shall be deemed
in default with regard to any such payments should the same not be made by the
date on which they are due.

      27.   OPTION TO EXTEND LEASE TERM

      A. Provided Tenant is not in default hereunder and has performed all of
its covenants and obligations hereunder, Tenant shall have one (1) option to
extend the Term of this Lease (the "Option") for a period of one hundred
nineteen (119) months upon the same terms and conditions, except for Basic
Monthly Rental.


                                       25
<PAGE>   26
                  The Basic Monthly Rental during the first year of the
extension shall be adjusted on the alter of August 1, 1999 or the first (1st)
day of the one hundred twentieth (120th) month (the "Rental Adjustment Date"),
to the lesser of the following:

                  (a) Fixed Adjustment -- the Basic Monthly Rental shall be
increased to Eighty-One Thousand Nine Hundred Forty-Five and 17/100 dollars
($81,945.17) or

                  (b) Fair Market Rental Value Adjustment -- The Basic Monthly
Rental shall be increased to ninety-five percent (95%) of the "fair market
rental value" of the Premises, determined in the following manner:

                 1.     Not later than one hundred (100) days prior to the
                        applicable Rental Adjustment Date, Landlord and Tenant
                        shall meet in an effort to negotiate, in good faith, the
                        fair market rental value of the Premises as of such
                        Rental Adjustment Date. If Landlord and Tenant have not
                        agreed upon the fair market rental value of the Premises
                        at least ninety (90) days prior to the applicable Rental
                        Adjustment Date, the fair market rental value shall be
                        determined by appraisal, by one or more brokers (herein
                        called "broker(s)") as provided below. Said broker(s)
                        shall have at least five (5) years' experience in the
                        sales and leasing of commercial real property in the are
                        in which the Premises is located.

                 2.     If Landlord and Tenant are not able to agree upon the
                        fair market rental value of the Premises within the
                        prescribed time period, then Landlord and Tenant shall
                        attempt to agree in good faith upon a single Broker not
                        later than seventy-five (75) days prior to the
                        applicable Rental Adjustment Date. If Landlord and
                        Tenant are unable to agree upon a single Broker within
                        such time period, then Landlord and Tenant shall each
                        appoint one Broker not later than sixty-five (65) days
                        prior to the Applicable Rental Adjustment Date. Within
                        ten (10) days thereafter, the two (2) appointed Brokers
                        shall appoint a third (3rd) Broker. If either Landlord
                        or Tenant fails to appoint its Broker within the
                        prescribed time period, the single Broker appointed
                        shall determine the fair market rental value of the
                        Premises. If both parties fail to appoint Brokers within
                        the prescribed time periods, then the first Broker
                        thereafter selected by a party shall determine the fair
                        market rental value of the Premises. Each party shall
                        bear the cost of its own Broker and the parties shall
                        share equally the cost of its own Broker and the parties
                        shall share equally the cost of the single or third
                        Broker, if applicable.


                                       26
<PAGE>   27
                 3.     For the purposes of such appraisal, the term "fair
                        market rental value" shall mean the price that a ready
                        and willing Tenant would pay, as of the applicable
                        Rental adjustment Date, as monthly rent to a ready and
                        willing Landlord of property comparable to the Premises
                        if such property were exposed for lease on the open
                        market for a reasonable period of time and taking into
                        account all of the purposes for which such property may
                        be used. If a single Broker is chosen, then such Broker
                        shall determine the fair market rental value of the
                        Premises. Otherwise, the fair market rental value of the
                        Premises shall be the arithmetic average of the two (2)
                        of the three (3) appraisals which are closest in amount,
                        and the third (3rd) appraisal shall be disregarded. In
                        no event, however, shall the Basic Monthly Rental be
                        reduced by reason of such computation. Landlord and
                        Tenant shall instruct the Broker(s) to complete the
                        determination of the fair market rental value not later
                        than thirty (30) days prior to the applicable Rental
                        Adjustment Date. If the fair market rental value is not
                        determined prior to the applicable Rental Adjustment
                        Date, then Tenant shall pay to Landlord the Basic
                        Monthly Rental applicable to the Premises immediately
                        prior to such extension, until the fair market rental
                        value is determined. When the fair market rental value
                        of the Premises is determined, Landlord shall deliver
                        notice thereof to Tenant, and Tenant shall pay to
                        Landlord, within ten (10) days after receipt of such
                        notice, the difference between the Basic Monthly Rental
                        actually paid by Tenant to Landlord and the new Basic
                        Monthly Rental determined hereunder.

                        Thereafter, every twelve (12) months after commencement
of the extension, the Basic Monthly Rental shall be increased by three percent
(3%) and shall be payable each and every month until further adjusted.

            (i) Tenant shall exercise said Option only by giving written notice
to Landlord not earlier than one hundred eighty (180) days nor later than one
hundred twenty (120) days, prior to the end of the Term.

            (ii) It is understood and agreed that this Option is personal to
Penril Corp., or its successors as a result of any sale, transfer,
consolidation, merger or reorganization of a majority of the voting stock of
Tenant, or to an assignee of this Lease that is a successor in interest to
Tenant's DataComm Division in accordance with Section 21.I., and is not
otherwise transferable; in the even of any assignment, except those stated
above, or subleasing of any or all of the Premises said Option shall be null and
void.

same or of any other terms, covenant, or condition contained in this Lease.
Landlord's or Tenant's consent to, or approval of any act shall not be deemed to
render unnecessary the obtaining of Landlord's or Tenant's consent to, or
approval of, any subsequent act by Tenant or Landlord. The acceptance of rent or
other sums payable hereunder by Landlord shall not be a waiver of any preceding

of such preceding breach at the time of acceptance of such rent, or sum
equivalent to rent.

      D.    Short Form

this Lease.

      F.    Examination of Lease

and Tenant.

      G.    Severability

                  If any term or provision of this Lease or the application
thereof to any person or circumstance shall, to any extent, be invalid or
unenforceable, the remainder of this Lease, or the application of such term or
provision to persons or circumstances other than those to which it is held

provision of this Lease shall be valid and be enforced to the fullest extent

                              RULES AND REGULATIONS


      The following Rules and Regulations shall be in effect at the Premises.
Landlord reserves the right to adopt reasonable modifications and additions
hereto. In the case of any conflict between these regulations and the Lease, the
Lease shall be controlling.

      1. Except with the prior written consent of Landlord, there shall be no
retail sales or any manufacturing of any kind in or from the Premises, or any
business other than that specifically provided for in the Lease.

      2. Landlord reserves the right to prohibit personal goods and services
vendors from access to the Premises, except upon such reasonable terms and
conditions including, but not limited to, the provision for insurance coverage,
as are related to the safety, care and cleanliness of the Premises, the
preservation of good order thereon, and the relief of any financial or other
burden on Landlord occasioned by the presence of such vendors or the sale by
them of personal goods or services to Tenant or its employees. If reasonably
necessary for the accomplishment of these purposes, Landlord may exclude a
particular vendor entirely or limit the number of vendors who may be present at
any one time in the Premises. The term "personal goods or services vendors"
means persons who periodically enter the Premises for the purpose of conducting
their business on the Premises. "Personal goods or services" include, but are
not limited to, drinking water and other beverages, food, barbering services,
and shoeshining services.

      3. The sidewalks, halls, passages and stairways shall not be obstructed by
Tenant or used by it for any purpose other than for ingress to and egress from
the Premises. The halls, passages, entrances, stairways, balconies and roof are
not for the use of the general public, and Landlord shall in all cases retain
the right to control and prevent access thereto by all persons whose presence in
the judgment of Landlord shall be prejudicial to the safety, character,
reputation and interests of the Premises and Tenant, provided that nothing
herein contained shall be construed to prevent such access to persons with whom
Tenant normally deals only for the purpose of conducting its business on the
Premises (such as clients, customers, office suppliers and equipment vendors,
and the like) unless such persons are engaged in illegal activities. Tenant and
its employees hall not go upon the roof of the Premises without the written
consent of Landlord.

      4. The sashes, sash doors, windows, glass, and any lights or skylights
that reflect or admit light into the halls for other places of the Premises,
shall not be covered or obstructed. The toilet rooms, water and wash closets and
other water apparatus shall not be used for any purpose other than that for
which they were constructed, and no foreign substance of any kind whatsoever
shall be thrown therein, and the expense of any breakage, stoppage or damage,
resulting from the violations of this rule shall be borne by Tenant, or its
clerks, agents, employees, or visitors, who shall have caused it.


                                       35
<PAGE>   36
      5. No sign, advertisement or notice from the exterior of the Premises
shall be inscribed, painted or affixed by Tenant to any part of the Premises
without the prior written consent of Landlord. If Landlord shall have given such
consent at any time, whether before or after the execution of this Lease, such
consent shall in no way operate as a waiver or release of any of the provisions
hereof or of this Lease, and shall be deemed to relate only to the particular
advertisement or notice so consented to by Landlord and shall not be construed
as dispensing with the necessity of obtaining the specific written consent of
Landlord with respect to each and every sign, advertisement or notice other than
the particular sign, advertisement or notice, as the case may be, so consented
to by Landlord.

      6. In order to maintain in the outward professional appearance of the
Premises, all window coverings to be installed at the Premises shall be subject
to Landlord's prior approval. If Landlord, by a notice in writing to Tenant,
shall object to any curtain, blind, shade or screen attached to, or hung in, or
used in connection with, any window or door of the Premises, such use of such
curtain, blind, shade or screen shall be forthwith discontinued by Tenant. No
awnings shall be permitted on any part of the Premises.

      7. Tenant shall not do or permit anything to be done in the Premises, or
bring or keep anything therein, which shall in any way increase the rate of fire
insurance on the Premises, or on the property kept therein, or conflict with the
regulations of the Fire Department or the fire laws, or with any insurance
policy upon the Premises, or any part thereof, or with any rules and ordinances
established by the Health Department or other governmental authority.

      8. No safe or other objects heavier than the floor load of the Premises
shall be brought into or installed in the Premises. Landlord shall have the
power to prescribe the weight and position of such safes or other objects which
shall, if considered necessary by Landlord, stand on three-inch thick wood
strips to distribute the weight. The moving of safes shall occur only between
such hours as may be designated by, and only upon previous notice to, the
manager of the Premises, and the persons employed to move safes in or out of the
Premises, and the persons employed to move safes in or out of the Premises must
be acceptable to Landlord.

      9. Tenant shall not sweep or throw or permit to be swept or thrown from
the Premises any dirt or other substance into any of the corridors or halls, or
out of the doors or windows or stairways of the Premises, and Tenant shall not
us, keep, or permit to be used or kept, any foul or noxious gas or substance in
the Premises, or permit or suffer the Premises to be occupied or used in a
manner offensive or objectionable to Landlord by reason of noise, odors and/or
vibrations.

      10. Except for microwave ovens and coffee makes, no cooking shall be done
or permitted by Tenant on the Premises, nor shall offices in the Premises be
used for the storage of merchandise or for lodging.


                                       36
<PAGE>   37
      11. Tenant shall not use or keep in the Premises any kerosene, gasoline,
or flammable fluid or any other illuminating material, or use any method of
heating other than that supplied by Landlord, except as otherwise provided
herein.

      12. If Tenant desires telephone or telegraph connections, Landlord will
direct electricians as to where and how the wires are to be introduced. No
boring or cutting for wires or otherwise shall be made without directions from
Landlord.

      13. Tenant, upon the termination of its tenancy, shall deliver to Landlord
all the keys of offices, rooms and toilet rooms which shall have been furnished
to Tenant or which Tenant shall have made, and in the event of loss of any keys
so furnished, shall pay Landlord therefor.

      14. Tenant shall not lay linoleum or other similar floor covering so that
the same shall be affixed to the floor of the Premises in any manner, except by
a paste, or other material which may easily be removed with water. The method of
affixing any such linoleum or other similar floor covering to the floor, as well
as the method of affixing carpets or rugs to the Premises, shall be subject to
approval by Landlord. The expense of repairing any damage resulting from a
violation of these rules by Tenant, its agents, contractors, employees invitees
or visitors shall be borne by Tenant.

      15. Landlord shall in no case be liable for damages for the admission to
or exclusion from the Premises of any person whom Landlord has the right to
exclude under Rule 3 above. In case of invasion, mob, riot, public excitement,
or other commotion, Landlord reserves the right but shall not be obligated to
prevent access to the Premises during the continuance of the same by closing the
doors or otherwise, for the safety of Tenant and protection of property in the
Premises.

      16. Tenant shall see that the windows and doors of the Premises are closed
and securely locked before leaving the Premises and Tenant shall exercise
extraordinary care and caution before Tenant or Tenant's employees leave the
Premises, and that all electricity, gas or air shall likewise be carefully shut
off, so as to prevent waste or damage, and for any default or carelessness
Tenant shall make good all injuries sustained by the Premises or Landlord.

      17. Tenant shall not, except in the case of an emergency, alter any lock
or install a new or additional lock or any bolt on any door of the Premises
without prior written consent of Landlord. If Landlord shall give its consent,
Tenant shall in each case furnish Landlord with a key for any such lock.

      18. Tenant shall not install equipment such as, but not limited to,
electronic tabulating or computer equipment, requiring electrical or
air-conditional service in excess of those to be provided by Landlord under the
Lease.

      19. No bicycle, or shopping cart, or other vehicle or any animal shall be
brought into the Premises or the halls, corridors or any part of the Premises by
Tenant.


                                       37
<PAGE>   38
      20. Landlord shall have the right to prohibit the use of the name of
NorthTech Business Park or any other publicity by Tenant which in Landlord's
opinion tends to impair the reputation of NorthTech Business Park or its
desirability, and upon written notice from Landlord, Tenant will refrain from or
discontinue such publicity.

      21. Tenant shall have the right to place additional trash storage
containers (dumpster type) in the parking lot as may be required for the normal
business operations of Tenant, provided, however; that said containers shall be

conditions, agreements, representations and warranties set forth herein, and
other good and valuable consideration, the receipt and sufficiency of which is
acknowledged by each of the parties, the parties do hereby agree as follows:

                  6. Section 9.B of the Lease Agreement provides that, except
for those items Landlord is responsible for pursuant to Section 10.A of the
Lease Agreement, Tenant shall, at Tenant's sole cost and expense, promptly
comply with all laws, statutes, ordinances and governmental rules and

or any part of the building or Northtech Business Center for which Tenant is
responsible (or which effected by Tenant's occupancy or use of the Premises) not
being in compliance with laws, including without


                                        2
<PAGE>   41
limitation the ADA, at any time, whether occurring before or after the execution
of this Amendment.

                  8. This Amendment does not and shall not be deemed to waive or
release Tenant from any obligation or liability under the Lease, including
without limitation those set forth in Section 9.B of the Lease Agreement.

                  9. Except as set forth herein, the Lease is unchanged and
shall remain in full force and effect.

                  IN WITNESS WHEREOF, the parties hereto have executed this
Amendment as of the date first written hereinabove.

5. EMPLOYEES TO WHOM OPTIONS MAY BE GRANTED. Options may be granted in each
calendar year or portion thereof while the Plan is in effect to such of the
Employees as the Committee, in its discretion, shall determine. In determining
the Employees to whom Options shall be granted and the number of Shares to be
issued or subject to purchase or issuance under such Options, the Committee
shall take into account the recommendations of the Company's management as to
the duties of the respective Employees, their present and potential
contributions to the success of the Company and its Subsidiaries, and such other
factors as the Committee shall deem relevant in connection with accomplishing
the purposes of the Plan; provided however, no Employee may receive Options to
acquire more than 500,000 Shares in any one calendar year. No Option shall be
granted to any member of the Committee so long as his or her membership on the
Committee continues or to any member of the Board who is not also an Employee of
the Company or any Subsidiary.

6.       TYPES AND BASIC TERMS OF OPTIONS.

         6.1 Types of Options. Options granted under the Plan may be (i)
Incentive Stock Options, (ii) Non-Qualified Stock Options or (iii) a combination
of the foregoing. The Option Agreement shall designate whether an Option is an
Incentive Stock Option or a Non-Qualified Stock Option and separate Option
Agreements shall be issued for each type of Option when a combination of an
Incentive Stock Option and a Non-Qualified Stock Option are granted on the same
date to the same Employee. Any Option which is designated as a Non-Qualified
Stock Option shall not be treated by the Company or the Employee to whom the
Option is granted as an Incentive Stock Option for federal income tax purposes.

         6.2 Option Price. The option price per Share of any Non-Qualified Stock
Option granted under the Plan shall be the Fair Market Value of the Shares
covered by the Option on the date the Option is granted unless the Committee, in
its sole discretion, determines to set the option price at an amount less than
or greater than the Fair Market Value of the Shares on such date. The option
price per Share of any Incentive Stock Option granted under the Plan shall not
be less than the Fair Market Value of the Shares covered by the Option on the
date the Option is granted.

                  Notwithstanding anything herein to the contrary, the option
price per Share of any Incentive Stock Option granted to an Employee Stockholder
shall not be less than one hundred ten percent (110%) of the Fair Market Value
of the Shares covered by the Option on the date the Option is granted.

         6.3 Term of Options. Options granted hereunder shall be exercisable for
a Term of not more than ten (10) years from the date of grant thereof, but shall
be subject to earlier termination as hereinafter provided. Each Option Agreement
issued hereunder shall specify the Term of the Option, which shall be determined
by the Committee in accordance with its discretionary authority hereunder.

                  Notwithstanding anything herein to the contrary, if an
Incentive Stock Option is granted to an Employee Stockholder, then such
Incentive Stock Option shall not be exercisable more


                                        5
<PAGE>   6
than five (5) years from the date of grant thereof, but shall be subject to
earlier termination as hereinafter provided.

         6.4 Vesting of Options. Unless otherwise determined by the Committee,
in its discretion, and set forth in the related Option Agreement, an Option may
be exercised, prior to its expiration or termination, within the following time
limitations:

                  6.4.1 After one (1) year from the date of grant, it may be
exercised as to not more than thirty percent (30%) of the Shares originally
subject to the Option.

                  6.4.2 After two (2) years from the date of grant, it may be
exercised as to not more than an aggregate of sixty percent (60%) of the Shares
originally subject to the Option.

                  6.4.3 After three (3) years from the date of grant, it may be
exercised as to any and all of the Shares subject to the Option.

7. LIMIT ON FAIR MARKET VALUE OF INCENTIVE STOCK OPTIONS. No Employee may be
granted an Incentive Stock Option hereunder to the extent that the aggregate
fair market value (such fair market value being determined as of the date of
grant of the option in question) of the stock with respect to which incentive
stock options are first exercisable by such Employee during any calendar year
(under all such plans of the Employee's employer corporation, its Parent, if
any, and its Subsidiaries, if any) exceeds One Hundred Thousand Dollars
($100,000). For purposes of the preceding sentence, options shall be taken into
account in the order in which they were granted. Any Option granted under the
Plan which is intended to be an Incentive Stock Option, but which exceeds the
limitation set forth in this Section 7, shall be a Non-Qualified Stock Option.

8. DATE OF GRANT. The date of grant of an Option granted hereunder shall be the
date on which the Committee acts in granting the Option.

9. EXERCISE OF RIGHTS UNDER OPTIONS.

         9.1 Notice of Exercise. An Employee entitled to exercise an Option
shall do so by delivery of a written notice to that effect specifying the number
of Shares with respect to which the Option is being exercised and any other
relevant information the Committee may require. The notice shall be accompanied
by payment in full of the purchase price of any Shares to be purchased, which
payment may be made in cash or, with the Committee's approval (which in the case
of Incentive Stock Options must be given at the time of grant), in Shares valued
at Fair Market Value at the time of exercise or a combination thereof. No Shares
shall be issued upon exercise of an Option until full payment has been made
therefor. All notices or requests provided for herein shall be delivered to the
Company's Secretary, or such other person as the Committee may designate.

         9.2 Cashless Exercise Procedures. The Company, in its sole discretion,
may establish procedures whereby an Employee, subject to the requirements of
Rule 16b-3, Regulation T, federal income tax laws, and other federal, state and
local tax and securities laws, can exercise an Option


                                        6
<PAGE>   7
or a portion thereof without making a direct payment of the option price to the
Company; provided, however, that these cashless exercise procedures shall not
apply to Incentive Stock Options which are outstanding on the date the Company
establishes such procedures unless the application of such procedures to such
Options is permitted pursuant to the Code and the regulations thereunder without
affecting the Options' qualification under Code Section 422 as Incentive Stock
Options. If the Company so elects to establish a cashless exercise program, the
Company shall determine, in its sole discretion, and from time to time, such
administrative procedures and policies as it deems appropriate and such
procedures and policies shall be binding on any Employee wishing to utilize the
cashless exercise program.

10. OTHER OPTION TERMS AND CONDITIONS. Each Option or each Option Agreement
setting forth an Option shall contain such other terms and conditions not
inconsistent herewith as shall be approved by the Committee.

11. EXECUTION BY EMPLOYEE OF CERTAIN AGREEMENTS UPON GRANT OF AN OPTION. As a
condition of the grant of an Option, an Employee must enter into the following
agreement with the Company: (a) a Non-Interference Agreement ("Non- Interference
Agreement") and (b) an Assignment of Inventions and Non-Disclosure Agreement
("Non-Disclosure Agreement"; and together with the Non-Interference Agreement,
the ("Company Agreements"). An Employee shall not be permitted to exercise any
Option granted under the Plan unless and until such Employee has executed and
delivered to the Company each of the Company Agreements, including any and all
amendments, modifications or extensions requested by the Company.

12. RIGHTS OF OPTION HOLDER. The holder of an Option shall not have any of the
rights of a stockholder with respect to the Shares subject to purchase or
receipt under the Option, except to the extent that one or more certificates for
such Shares shall be issuable to the holder upon the due exercise of the Option
and the payment in full of the purchase price therefor.

13. NONTRANSFERABILITY OF OPTIONS. An Option shall not be transferable other
than: (a) by will or the laws of descent and distribution, and an Option subject
to exercise may be exercised, during the lifetime of the holder of the Option,
only by the holder or in the event of death, the holder's Successor, or in the
event of disability, the holder's personal representative, or (b) pursuant to a
qualified domestic relations order, as defined in the Code or ERISA or the rules
thereunder; provided, however, that an Incentive Stock Option may not be
transferred pursuant to a qualified domestic relations order unless such
transfer is otherwise permitted pursuant to the Code and the regulations
thereunder without affecting the Option's qualification under Code Section 422
as- an Incentive Stock Option.

14. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. In the event of changes in the
outstanding Shares by reason of stock dividends, stock splits,
reclassifications, recapitalizations, mergers, consolidations, combinations, or
exchanges of shares, separations, reorganizations or liquidations, or similar
events, or in the event of extraordinary cash or non-cash dividends being
declared with respect to the Shares, or similar transactions or events, the
number and class of Shares available


                                        7
<PAGE>   8
under the Plan in the aggregate, the number and class of Shares subject to
Options theretofore granted, applicable purchase prices and all other applicable
provisions, shall, subject to the provisions of the Plan, be equitably adjusted
by the Committee (which adjustment may, but need not, include payment to the
holder of an Option, in cash or in shares, in an amount equal to the difference
between the price at which such Option may be exercised and the then current
fair market value of the Shares subject to such Option as equitably determined
by the Committee). The foregoing adjustment and the manner of application of the
foregoing provisions shall be determined by the Committee, in its sole
discretion. Any such adjustment may provide for the elimination of any
fractional share which might otherwise become subject to an Option.

15. CHANGE IN CONTROL. Notwithstanding anything to the contrary in the Plan or
any Option Agreement, in the case of a Change in Control of the Company, each
Option granted under the Plan shall terminate ninety (90) days after the
occurrence of such Change in Control but, in the event of any such termination,
an Option holder shall have the right, commencing at least five (5) days prior
to such Change in Control and subject to any other limitation on the exercise of
such Option in effect on the date of exercise to immediately exercise any Option
in full, without regard to any vesting limitations, to the extent they shall not
have been theretofore exercised. The foregoing provision shall not apply to the
holder of an Option to the extent that the application of such provision would
cause such Option, when aggregated with all other payments in the nature of
compensation due to the holder of the Option, to be treated as an "excess
parachute payment" within the meaning of Section 280G of the Code. If a Change
in Control would be deemed to have occurred under paragraph 2.2.3(a) hereof
except for the fact that the President of the Company is the President, Chairman
or Chief Executive Officer of the Company or the surviving entity, then if the
Employee's relationship with the surviving entity is terminated within nine (9)
months of the merger or consolidation for any reason other than good cause
(which shall not include downsizing or consolidation of resources), as
determined by the surviving entity, then a Change in Control shall be deemed to
have occurred upon such termination with respect to the options of such
terminated employee.

16. FORMS OF OPTIONS. Nothing contained in the Plan nor any resolution adopted
or to be adopted by the Board or by the stockholders of the Company shall
constitute the granting of any Option. An Option shall be granted hereunder only
by action taken by the Committee in granting an Option. Whenever the Committee
shall designate an Employee for the receipt of an Option, the Company's
Secretary, or such other person as the Committee may designate, shall forthwith
send notice thereof to the Employee, in such form as the Committee shall
approve, stating the number of Shares subject to the Option, its Term, and the
other terms and conditions thereof. The notice shall be accompanied by a written
Option Agreement in such form as may from time to time hereafter be approved by
the Committee, which shall have been duly executed by or on behalf of the
Company. If the surrender of previously issued Options is made a condition of
the grant, the notice shall set forth the pertinent details of such condition.
Execution by the Employee to whom such Option is granted of said Option
Agreement in accordance with the provisions set forth in this Plan shall be a
condition precedent to the exercise or receipt of any Option.


                                        8
<PAGE>   9
17.      TAXES.

         17.1 Right to Withhold Required Taxes. The Company shall have the right
to require a person entitled to receive Shares pursuant to the exercise of an
Option under the Plan to pay the Company the amount of any taxes which the
Company is or will be required to withhold with respect to such Shares before
the certificate for such Shares is delivered pursuant to the Option.
Furthermore, the Company may elect to deduct such taxes from any other amounts
then payable in cash or in shares or from any other amounts payable any time
thereafter to the Employee. If the Employee disposes of Shares acquired pursuant
to an Incentive Stock Option in any transaction considered to be a disqualifying
disposition under Sections 421 and 422 of the Code, the Employee shall notify
the Company of such transfer and the Company shall have the right to deduct any
taxes required by law to be withheld from any amounts otherwise payable then or
at any time thereafter to the Employee.

         17.2 Employee Election to Withhold Shares. Subject to specific
Committee approval (which in the case of Incentive Stock Options must be given
at the time of grant), an Employee may elect to satisfy the tax liability with
respect to the exercise of an Option by having the Company withhold Shares
otherwise issuable upon exercise of the Option; provided, however, that if an
Employee is subject to Section 16(b) of the Exchange Act at the time the Option
is exercised, such election must satisfy the requirements of Rule 16b-3.

18. TERMINATION OF THE PLAN. The Plan shall terminate ten (10) years from the
date hereof, and an Option shall not be granted under the Plan after that date
although the terms of any Options may be amended at any date prior to the end of
its Term in accordance with the Plan. Any Options outstanding at the time of
termination of the Plan shall continue in full force and effect according to the
terms and conditions of the Option and this Plan.

19. AMENDMENT OF THE PLAN. The Plan may be amended at any time and from time to
time by the Board, but no amendment without the approval of the stockholders of
the Company shall be made if stockholder approval under Section 422 of the Code
or Rule 16b-3 would be required. Notwithstanding the discretionary authority
granted to the Committee in Section 4 of the Plan, no amendment of the Plan or
any Option granted under the Plan shall impair any of the rights of any holder,
without the holder's consent, under any Option theretofore granted under the
Plan.

20. DELIVERY OF SHARES ON EXERCISE. Delivery of certificates for Shares pursuant
to the grant or exercise of an Option may be postponed by the Company for such
period as may be required for it with reasonable diligence to comply with any
applicable requirements of any federal, state or local law or regulation or any
administrative or quasi-administrative requirement applicable to the sale,
issuance, distribution or delivery of such Shares. The Committee may, in its
sole discretion, require an Employee to furnish the Company with appropriate
representations and a written investment letter prior to the exercise of an
Option or the delivery of any Shares pursuant thereto.

21. FEES AND COSTS. The Company shall pay all original issue taxes on the
exercise of any Option granted under the Plan and all other fees and expenses
necessarily incurred by the Company in connection therewith.

22. EFFECTIVENESS OF THE PLAN. The Plan shall become effective when approved by
the Board. The Plan shall thereafter be submitted to the Company's stockholders
for approval and unless the Plan is approved by the Company's stockholders at a
meeting duly held in accordance with Delaware law within twelve (12) months
after being approved by the Board, the Plan and all Options made under it shall
be void and of no force and effect. In aid of this provision any Options granted
prior to the approval of the Plan by the Company's stockholders shall be
conditioned upon receipt of such approval.

23. OTHER PROVISIONS. As used in the Plan and in Option Agreements and other
documents prepared in implementation of the Plan, references to the masculine
pronoun shall be deemed to refer to the feminine or neuter, and references in
the singular or the plural shall refer to the plural or the singular, as the
identity of the person or persons or entity or entities being referred to may
require. The captions used in the Plan and in such Options and other documents
prepared in implementation of the Plan are for convenience only and shall not
affect the meaning of any provision hereof or thereof.

24. DELAWARE LAW TO GOVERN. This Plan shall be governed by and construed in
accordance with the laws of the State of Delaware.

         6.       Exercise of Award.

                  (a) In order to exercise the Option, the person or persons
entitled to exercise it shall deliver to the Secretary of the Company written

she is entitled to do so immediately before such termination, at any time within
three months after such termination, but not beyond the original Term hereof and

the Option that has not vested as of the date of the Optionee's death shall
automatically terminate.

         10. Disability of Optionee. If the employment or other relationship
with the Company of the Optionee terminates on account of his or her having
become "disabled" as defined in Section 22(e)(3) of the Code then (i) the Option
may be exercised to the extent that the Optionee was entitled to do so

         12. Change in Control. Notwithstanding anything in this Award Agreement
to the contrary, in the case of a Change in Control of the Company as defined in
Section 2.2 of the Plan, and subject to Section 15 of the Plan, the Optionee
shall have the right, commencing at least five (5) days prior to such Change in
Control, to immediately exercise the Option in full, without regard to any
vesting limitations; provided, however, that this Section 12 shall not apply to
the extent that such event would cause this Award, when aggregated with all
other payments in the nature of compensation due the Optionee, to be treated as
an"excess parachute payment" as defined in Section 280G(b) (or its successor) of
the Code. For purposes of determining whether this Award constitutes an "excess
parachute payment," this Award shall be deemed to be considered part of the
"base amount" as defined in Section 280G(b)(3) of the Code and part of the
"reasonable compensation" referred to in Section 280G(b)(4) of the Code only to
the extent any other payments to the Optionee in (the nature of compensation
taken into consideration under Section 280G do not equal or exceed the sum of
(x) such "base amount" and (y) such "reasonable compensation" in excess of such
"base amount" unless the Committee, in its discretion, determines that an
employment agreement or other arrangement with the Optionee requires "excess
parachute payments" to be computed in some other manner, in accordance with
Section 280G of the Code.

         13. Taxes. The Company has the right to require a person entitled to
receive Shares pursuant to the exercise of any Option under the Plan to pay the
Company the amount of any taxes which the Company is or will be required to
withhold with respect to such Shares before the certificate of such Shares is
delivered. Furthermore, the Company may elect to deduct such taxes from any
other amounts payable in cash or in shares or from any other amounts payable
anytime thereafter to the Optionee.

         14. Adjustments Upon Changes in Capitalization. In the event of changes
in all of the outstanding Shares by reason of stock dividends, stock splits,
reclassifications, recapitalizations, mergers, consolidations, combinations, or
exchanges of shares, separations, reorganizations, liquidations, or similar
events, or in the event of extra ordinary cash or non-cash dividends being
declared with respect to the Shares, or similar transactions or events, the
number and class of Shares subject to the Option hereby granted, the option
price and all other applicable provisions thereof shall, subject to the
provisions of the Plan, be correspondingly equitably adjusted by the Committee
(which adjustment may, but need not, include payment to the holder of the
Option, in cash or in shares, in any amount equal to the difference between the
option price and the then current Fair Market Value of the Shares subject to the
Option as equitably determined by the Committee), as it shall decide in its sole
discretion. Any such adjustment may provide for the elimination of any
fractional share which might otherwise be subject to the Option.

         15. Delivery of Shares on Exercise. Delivery of certificates for Shares
pursuant to the exercise of the Option may be postponed by the Company for such
period as may be required for it with reasonable diligence to comply with any
applicable requirements of any federal, state or local law or regulation of any
administrative or quasi-administrative requirement applicable to the sale,
issuance, distribution or delivery of such Shares. The Committee may, in its
sole discretion, require the holder of the Option to furnish the Company with
appropriate representations and a written



                                        4
<PAGE>   5
investment letter prior to the exercise of the Option or the delivery of any
Shares pursuant to the Option.

         16. Incorporation of Provisions of the Plan. All of the provisions of
the Plan pursuant to which this Option is granted are hereby incorporated by
reference and made a part hereof as if specifically set forth herein, and to the
extent there exists any conflict between this Award Agreement and the terms
contained in the aforesaid Plan, the terms of the Plan shall prevail. To the
extent any capitalized terms are not otherwise defined herein, they shall have
the meaning set forth in Section 2 of the Plan. If this Award Agreement is dated
prior to approval of the Plan by the Company's Stockholders, then the Option
granted is conditioned upon receipt of such approval.

         17. Waiver and Modification. The provisions of this Award Agreement may
not be waived or modified unless such waiver or modification is done in writing
and acknowledged by all the parties hereto.

         IN WITNESS WHEREOF, the Company has caused this Award Agreement to be
duly executed by one of its officers thereunto duly authorized, and the Optionee
has hereunto set his or her hand, all on the day and year first above written.

information the Committee may require. The notice shall be accompanied by
payment in full of the purchase price of any Shares to be purchased, which
payment shall be made in cash or by certificates of Shares held for more than
six (6) months, duly endorsed in blank equal in value to the purchase price of

16b-3, Regulation T, federal income tax laws, and other federal, state and local
tax and securities laws, can exercise an Option or a portion thereof without
making a direct payment of the option price to the Company. If the Company so
elects to establish a cashless exercise program, the Company shall determine, in
its sole discretion, and from time to time, such administrative procedures and
policies as it deems appropriate and such procedures and policies shall be
binding on any Director wishing to utilize the cashless exercise program.

rights of a stockholder with respect to the Shares subject to purchase or
receipt under his or her Option, except to the extent that one or more
certificates for such Shares shall be issuable to the holder upon the due
exercise of the Option and the payment in full of the purchase price therefor.

only by the holder, or in the event of death, the holder's Successor, or in the
event of disability, the holder's personal representative, or (b) pursuant to a
qualified domestic relations order, as defined in the Code or ERISA or the rules
thereunder.

outstanding Shares by reason of stock dividends, stock splits,
reclassifications, recapitalizations, mergers, consolidations, combinations, or
exchanges of shares, separations, reorganizations or liquidations, or similar
events, or in the event of extraordinary cash or non-cash dividends being

<PAGE>   7
granted, applicable purchase prices and all other applicable provisions, shall,
subject to the provisions of the Plan, be equitably adjusted by the Committee
(which adjustment may, but need not, include payment to the holder of an Option,
in cash or in shares, in an amount equal to the difference between the price at
which such Option may be exercised and the then current fair market value of the
Shares subject to such Option as equitably determined by the Committee). The
foregoing adjustment and the manner of application of the foregoing provisions
shall be determined by the Committee, in its sole discretion. Any such
adjustment may provide for the elimination of any fractional share which might
otherwise become subject to an Option.

12. CHANGE IN CONTROL. Notwithstanding anything to the contrary in the Plan or
in any Option Agreement, in the case of a Change in Control of the Company, each
Option granted under the Plan shall terminate on the later of (a) ninety (90)
days after the occurrence of such Change in Control and (b) seven (7) months
following the date of grant of an Option, and an Option holder shall have the
right, commencing at least five (5) days prior to such Change in Control and
subject to any other limitation on the exercise of such Option in effect on the
date of exercise, to immediately exercise any Option in full, without regard to
any vesting limitations, to the extent it shall not have been previously
exercised.

13. FORMS OF OPTIONS. An Option shall be granted hereunder on the date or dates
specified in the Plan. Whenever the Plan provides for the receipt of an Option
by a Director, the Company's Chief Financial Officer or such other person as the
Committee shall appoint, shall send notice thereof to the Director, in such form
as the Committee shall approve, stating the number of Shares subject to the
Option, its Term, and the other terms and conditions thereof The notice shall be
accompanied by a written Option Agreement, in such form as may from time to time
hereafter be approved by the Committee, which shall have been duly executed by
or on behalf of the Company. Execution by the Director to whom such Option is
granted of said Option Agreement in accordance with the provisions set forth in

to require a person entitled to receive Shares pursuant to the exercise of an
Option under the Plan to pay the Company the amount of any taxes which the
Company is or will be required to withhold, if any, with respect to such Shares
before the certificate for such Shares is delivered pursuant to the Option.
Furthermore, the Company may elect to deduct such taxes from any other amounts
then payable in cash or in shares or from any other amounts payable any time
thereafter to the Director.

         14.2 Director Election to Withhold Shares. A Director may satisfy the
withholding tax liability, if any, with respect to the exercise of an Option, by
having the Company withhold Shares otherwise issuable upon exercise of the
Option if such Director makes an election to do so which satisfies the
requirements of Rule 16b-3.

Shares shall be issued.

                  (b) No shares shall be issued until full payment therefor has

respect of such Shares until they are so issued.

         6. Nontransferability. The Option shall not be transferable other than:
(a) by will or the laws of descent and distribution, and the Option may be
exercised, during the lifetime of the Optionee, only by him or her or in the

the Optionee's personal representatives or (b) pursuant to a qualified domestic
relations order, as defined in the Internal Revenue code of 1986, as amended
(the "Code"), or ERISA, or the rules thereunder.

         7. Termination of Board Membership. In the event that the Optionee
(which, in the case of an Optionee who is a designee of a Board member, shall
mean, for purposes of this paragraph 7, such Board member) ceases to be a member

of the date the Optionee ceases to be a member of the Board, at any time within
seven months after such date, but not beyond the Term hereof and (b) the portion

paragraph 8, such Board member) dies or becomes disabled while he or she is a
member of the Board, or within seven months after he or she ceases to be a
member of the Board, then (a) the Option may be exercised to the extent the
Optionee was entitled to do so immediately before the time of his or her death
or disability, by the Optionee's Successor, at any time within one year after he
or she ceases to be a member of the Board on account of such death or
disability, but not beyond the Term hereof and (b) the portion of the Option
that has not vested as of the date of the Optionee's death or disability shall
automatically terminate.

         9. Change in Control. Notwithstanding anything in this Award Agreement
to the contrary, in the case of a Change in Control of the Company as defined in
Section 2.2 of the Plan, the Optionee shall have the right, commencing at least
five (5) days prior to such Change in Control and subject to any other
limitation on the exercise of such Option in effect on the date of exercise, to
immediately exercise the Option in full, without regard to any vesting
limitations. The Option shall terminate on the later of (a) ninety (90) days
after the occurrence of such Change of Control and (b) seven (7) months
following the Date of Grant.

         10. Taxes. The Company has the right to require a person entitled to
receive Shares pursuant to the exercise of any Option under the Plan to pay the
Company the amount of any taxes which the Company is or will be required to
withhold with respect to such Shares before the certificate of such Shares is
delivered. Furthermore, the Company may elect to deduct such taxes from any
other amounts payable in cash or in shares or from any other amounts payable
anytime thereafter to the Optionee.

         11. Adjustments Upon Changes in Capitalization. In the event of changes
in all of the outstanding Shares by reason of stock dividends, stock splits,
reclassifications, recapitalizations, mergers, consolidations, combinations, or
exchanges of shares, separations, reorganizations, liquidations, or similar
events, or in the event of extra ordinary cash or non-cash dividends being
declared with respect to the Shares, or similar transactions or events, the
number and class of Shares subject to the Option hereby granted, the option
price and all other applicable provisions thereof shall, subject to the
provisions of the Plan, be correspondingly equitably adjusted by the Committee
(which adjustment may, but need not, include payment to the holder of the
Option, in cash or in shares, in any amount equal to the difference between the
option price and the then current Fair Market Value of the Shares subject to the
Option as equitably determined by the Committee), as it shall decide in its sole
discretion. Any such adjustment may provide for the elimination of any
fractional share which might otherwise be subject to the Option.

         12. Delivery of Shares on Exercise. Delivery of certificates for Shares
pursuant to the exercise of the Option may be postponed by the Company for such
period as may be required for it with reasonable diligence to comply with any
applicable requirements of any federal, state or local law or regulation of any
administrative or quasi-administrative requirement applicable to the sale,
issuance, distribution or delivery of such Shares. The Committee may, in its
sole discretion, require

<PAGE>   4
the holder of the Option to furnish the Company with appropriate representations
and a written investment letter prior to the exercise of the Option or the
delivery of any Shares pursuant to the Option.

         13. Incorporation of Provisions of the Plan. All of the provisions of
the Plan pursuant to which this Option is granted are hereby incorporated by
reference and made a part hereof as if specifically set forth herein, and to the
extent there exists any conflict between this Award Agreement and the terms
contained in the aforesaid Plan, the terms of the Plan shall prevail. To the
extent any capitalized terms are not otherwise defined herein, they shall have
the meaning set forth in Section 2 of the Plan. If this Award Agreement is dated
prior to approval of the Plan by the Company's Stockholders, then the Option
granted is conditioned upon receipt of such approval.

         14. Waiver and Modification. The provisions of this Award Agreement may
not be waived or modified unless such waiver or modification is done in writing
and acknowledged by all the parties hereto.

         IN WITNESS WHEREOF, the Company has caused this Award Agreement to be
duly executed by one of its officers thereunto duly authorized, and the Optionee
has hereunto set his or her hand, all on the day and year first above written.

                                   ARTICLE VI

                                   TERMINATION

6.01 TERMINATION FOR BREACH

In the event of a material breach of a material provision of the Stock Purchase
Agreement or this Agreement by either party, the non-breaching party may, in
addition to any other remedies that it may have, terminate this Agreement
provided that it shall first give to the breaching party thirty (30) days
written notice specifying such breach and the breaching party shall offer a
remedy within said thirty days. If the default is not corrected by the offered
remedy and such continued default is noticed in writing, this Agreement shall
terminate if the default is not corrected within thirty (30) days of notice of
continued default.


6.02 TERMINATION BY CONSENT

This Agreement may be terminated, in whole or in part, by mutual written consent
of both parties.


6.03 EFFECT OF TERMINATION

(a) The respective obligations of ABI and Paradyne under the provisions of
Article V, and Article VII shall remain in force notwithstanding the termination
of this Agreement.

(b) In the event that Paradyne fails to cure a material breach, termination of
this Agreement pursuant to the provisions of this Article VI shall not affect or
alter the transfer of ownership specified in Section 1.03 or the grant of rights
in Section 1.04 or any other rights of ABI under this Agreement.

(c) Paradyne's termination of this Agreement pursuant to Section 6.01 shall not
affect the transfers made to ABI under Section 1.03 or the rights granted to ABI
under Section 1.04 which shall continue not withstanding such termination,
pursuant to the terms and restrictions hereof, unless termination of those
rights is permitted pursuant to Section 6.03 (e) or the equitable relief
obtained under Section 6.03 (g) provides otherwise.

(d) An "Unwind Condition" shall be deemed to exist if Paradyne's termination
pursuant to Section 6.01 occurs: (i) prior to Paradyne's receipt of all payments
due for the transfer of inventory as specified in Attachment B, or (ii) prior to
the date of registration of all shares pursuant to the Stock Purchase Agreement
("Registration Date"), or (iii) after the Registration Date, but prior to three
(3) months after the date of expiration or earlier waiver by ABI of the share
sale restrictions of Section 8.2 of the Stock Purchase Agreement ("Lock Up
Expiration Date"), and the material breach upon which the termination is based
is ABI's failure to use its



<PAGE>   14
best efforts to maintain registration for any shares as provided in Section 7.1
(c) of the Stock Purchase Agreement.

(e) If an Unwind Condition exists, then notwithstanding subsection (c) and in
addition to other remedies, Paradyne may elect to rescind this Agreement with
the following results:

         (i)      all rights, licenses, and immunities granted under this
                  Agreement, including, but not limited to, the rights granted
                  under Section 1.04, shall be terminated, and ABI shall
                  promptly destroy or deliver to Paradyne, at Paradyne's option,
                  all materials that embody or incorporate any PARADYNE
                  INTELLECTUAL PROPERTY then in the possession or control of
                  ABI; AND,

         (ii)     ABI shall re-transfer to Paradyne all right, title, and
                  interest in the HAWK TECHNOLOGY that was transferred under
                  Section 1.03, and return any inventory purchased under
                  Attachment B (less any items consumed); AND,

         (iii)    upon completion to Paradyne's reasonable satisfaction of the
                  provisions of (i) and (ii) above, Paradyne shall return to ABI
                  the consideration paid to Paradyne pursuant to Article III,
                  less the value of any items consumed and less the value (but
                  not more than $25,000) for any Engineering Support services
                  rendered under Section 4.02.1, where the calculation of the
                  value and amounts to be returned shall be subject to the
                  reasonable agreement of the parties, and if the parties are
                  unable to agree, then subject to the dispute resolution
                  procedures of Section 7.17.

(f) If Paradyne's termination pursuant to Section 6.01 occurs after the
Registration Date but prior to the Lock Up Expiration Date and the material
breach upon which the termination is based is not ABI's failure to use its best
efforts to maintain registration for any shares, in addition to such rights as
Paradyne may have under 6.03 (g), ABI shall waive all share sale restrictions of
the Stock Purchase Agreement remaining in effect as of such date, to the fullest
extent permitted by law.

(g) In the event of a material breach of a material provision of this Agreement
by ABI that is not cured within the notice period set forth in Section 6.01, the
parties acknowledge and agree that the remedies and provisions above shall not
be considered exclusive, and that, subject to Section 6.03 (c) Paradyne shall be
free to seek additional remedies and recourse under law or equity, in whatever
forum shall be appropriate. Not withstanding the provisions of 6.03 (c) ABI
acknowledges that the rights granted hereunder, and the nature of the PARADYNE
INTELLECTUAL PROPERTY, are such that Paradyne will suffer irreparable harm from
a material breach of the material provisions of this Agreement regarding
PARADYNE INTELLECTUAL PROPERTY not cured within the notice period set forth in
Section 6.01, and that therefore Paradyne shall be entitled to equitable relief,
including, without limitation, injunction, preliminary injunction, and specific
performance, as appropriate in the circumstances.

                                   ARTICLE VII

                            MISCELLANEOUS PROVISIONS

7.01 INDEMNIFICATION

(a) In the event that the HAWK TECHNOLOGY (excepting its associated hardware
elements) used for its inherent purposes, is held to constitute infringement of
a U.S. Patent, and the use of same is enjoined in the U.S., Paradyne shall, at
its option and its own expense, either (1) procure for ABI the right to continue
using HAWK TECHNOLOGY; or (2) replace the same with substantially functionally
equivalent non-infringing technology; or (3) modify the same so that it becomes
non-infringing.


(b) Paradyne shall have no liability or obligation under Section 7.01 for any
liability, loss, or damage caused by ABI's use of any TECHNICAL INFORMATION as
provided to ABI hereunder.

Paradyne represents that to the best of Paradyne's knowledge, the HAWK
TECHNOLOGY and the rights granted hereunder do not infringe any patents,
trademarks, service marks, trade names, copyrights, or trade secrets or other
proprietary rights of any other person or entity.

(c) ABI agrees that it will indemnify, defend, and hold harmless Paradyne, its
affiliates and its customers and their officers, directors, employees,
successors, and assigns (all hereinafter referred to in this clause as
"Paradyne") against and from any and all claims, damages, and liability,
including expenses and reasonable attorneys' fees, suffered by Paradyne
resulting from claims of intellectual property infringement, personal injury
and/or tangible property damage to third parties, including without limitation,
Paradyne's employees, caused by (1) ABI's contributions to the HAWK PRODUCT, (2)
the failure of HAWK PRODUCT to conform to HAWK TECHNOLOGY or defects in
materials and workmanship of the HAWK PRODUCT, (3) any failure on the part of
ABI to satisfy all claims for license fees, royalties, labor, equipment,
materials, and other obligations, (4) the negligent acts of ABI, arising out of
the performance under this Agreement, (5) ABI's breach of this Agreement, or (6)
claims for product liability.

Paradyne and ABI agree that if a claim of intellectual property infringement is
based on a combination of Paradyne's and ABI's contributions to the HAWK
PRODUCT, Paradyne shall retain responsibility for the defense and the parties
shall enter into "good faith" discussions as to the appropriate sharing of
liabilities, including the costs of defense and attorney fees. Absent reaching
such an agreement within a reasonable time, this issue may be resolved pursuant
to Section 7.17 (Disputes).

(d) Except as specifically provided in this Agreement, neither party shall have
any liability to the other for any claims, actions, liabilities, losses or
damages arising out of the sale, lease, services, or related activities with
respect to the products of the other party.

7.06 ASSIGNMENT

(a) Except as otherwise provided in this Section 7.06, the parties hereto have
entered into this Agreement in contemplation of personal performance by each
other and intend that neither this Agreement nor any of the rights or privileges
hereunder shall be assigned, transferred, shared or divided, by operation of

respect to the rights granted in the PARADYNE INTELLECTUAL PROPERTY (i) such
sale, transfer, or assignment does not violate the export laws of the United
States, (ii) is to an entity domiciled in a jurisdiction wherein the provisions
of this Agreement and related Agreements are reasonably enforceable, and (iii)
such entity is not less capable than ABI, and specifically undertakes in writing
addressed to Paradyne, to assure that it will perform the obligations of ABI
hereunder.

(c) Notwithstanding paragraph (a) above, Paradyne shall have the right to assign
this Agreement and to assign its rights and delegate its duties under this

                  (h) any notification or communication received by the Company
that any of its employees or consultants is 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 is violated by or would materially interfere with
the current or prospective services provided to the Company by the employee or
consultant or the use of his best efforts to promote the interests of the
Company or that would materially conflict with the Company's business as
currently conducted and proposed to be conducted;

                  (i) any claim or legal action or other proceeding threatened
or brought before any court, any arbitrator of any kind or any administrative
agency, or any governmental investigation, which could have a material adverse
effect on the Company's business, financial condition or results of operations;
or

                  (j) any other event or condition of any character which has
materially and adversely affected the Company's assets, liabilities, financial
condition or operations or prospects.

            3.7 Registration Rights. Except as provided for in Section 7 hereof,
the Company has not granted or agreed to grant any registration rights,
including piggyback rights, to any person or entity.

      4. Investor Representations and Warranties. Investor hereby represents and
warrants to the Company as of the Closing Date as follows:

            4.1 Organization and Standing. Paradyne is a corporation duly
organized and validly existing under, and by virtue of, the laws of the State of
Delaware and is in good standing as a domestic corporation under the laws of
said state and is qualified as a foreign corporation in all other jurisdictions
in which such qualification is required; provided, however, that Paradyne need
not be qualified in a jurisdiction in which its failure to qualify would not
have a material adverse effect on the business, properties, prospects or
financial condition of Paradyne.


                                       4
<PAGE>   8
            4.2 Corporate Power; Authorization. Paradyne has all requisite legal
and corporate power and has taken all requisite corporate action to execute and
deliver the Agreement and the Related Agreements. This Agreement and the Related
Agreements constitute the legal, valid and binding obligations of Paradyne,
enforceable against Paradyne in accordance with their respective terms, except
(A) as limited by applicable bankruptcy, insolvency, reorganization, moratorium,
and other laws of general application affecting enforcement of creditors' rights
generally, (B) as limited by laws relating to the availability of specific
performance, injunctive relief, or other equitable remedies, and (C) to the
extent the indemnification provisions contained herein may be limited by
applicable federal or state securities laws. The execution and delivery of this
Agreement and the Related Agreements does not, and the performance of this
Agreement and the Related Agreements and the compliance with the provisions
hereof will not materially conflict with, or result in a breach or violation of
the terms, conditions or provisions of, or constitute a default under, or result
in the creation or imposition of any lien pursuant to the terms of, the
Certificate of Incorporation or Bylaws of Paradyne. The execution and delivery
of this Agreement does not, and the performance of this Agreement and the
compliance with the provisions hereof will not materially conflict with, or
result in a breach or violation of the terms, conditions or provisions of, or
constitute a default under, or result in the creation or imposition of any lien
pursuant to the terms of, or any statute, law, rule or regulation or any state
or federal order, judgment or decree or any indenture, mortgage, lease or other
agreement or instrument to which Paradyne, or any of its properties, is subject.

            4.3 Investment Experience. Investor is an "accredited investor" as
defined in Rule 501 (a) under the Securities Act. Investor is generally aware of
the Company's business affairs and financial condition and has had access to and
has acquired sufficient information about the Company to reach an informed and
knowledgeable decision to acquire the Purchased Shares. Investor has such
business and financial experience as is required to give it the capacity to
protect its own interests in connection with the purchase of the Purchased
Shares. Notwithstanding the foregoing, Investor shall be entitled to rely on the
representations and warranties of the Company in Section 3.

            4.4 Investment Intent. Investor is purchasing the Purchased Shares
for investment for its own account only and not with a view to, or for resale in
connection with, any "distribution" thereof within the meaning of the Securities
Act. Investor understands that the Purchased Shares have not been registered
under the Securities Act or registered or qualified under any state securities
law in reliance on specific exemptions therefrom, which exemptions may depend
upon, among other things, the bona fide nature of Investor's investment intent
as expressed herein.

            4.5 Registration or Exemption Requirements. Investor further
acknowledges and understands that the Purchased Shares must be held indefinitely
unless they are subsequently registered under the Securities Act or an exemption
from such registration is available. Investor understands that the
certificate(s) evidencing the Purchased Shares will be imprinted with a legend
that prohibits the transfer of the Shares unless (i) they are registered or such
registration is not required, and (ii) if the transfer is pursuant to an
exemption from


                                       5
<PAGE>   9
registration other than Rule 144 under the Securities Act, and, if the Company
shall so request in writing, an opinion of counsel satisfactory to the Company
is obtained to the effect that the transaction is so exempt. In addition,
Investor will refrain from selling, transferring or otherwise disposing of any
Purchased Shares, or any interest therein, in such manner as to cause the
Company to be in violation of the registration requirements of the Securities
Act or applicable state securities or blue sky laws. Investor further
acknowledges that the Purchased Shares will be imprinted with a legend stating
that: "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN
ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE
SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY."

      5. Conditions of Investor's Obligations at Closing. The obligations of
Investor under this Agreement are subject to the fulfillment on or before the
Closing of each of the following conditions:

            5.1 Representations and Warranties. The representations and

of such Closing.

any, of any governmental authority or regulatory body of the United States or of
any state that are required in connection with the lawful issuance and sale of
the Securities pursuant to this Agreement shall be duly obtained and effective
as of the Closing.

            5.5 Proceedings and Documents. All corporate and other proceedings
in connection with the transactions contemplated at the Closing and all

received all such counterpart original and certified or other copies of such
documents as they may reasonably request.

            5.6 Execution of Technology Agreements. The Company shall have duly

<PAGE>   10
            5.8 Certificate of Transfer Agent. Investor shall have received a
certificate of the Company's transfer agent in a form reasonably satisfactory to
Investor, which certificate shall state that the Company has 30,000,000 shares
of Common Stock, $0.01 par value, and 3,000,000 shares of Preferred Stock, $0.01
par value authorized, and which shall state the outstanding capital stock of the
Company. The number of shares of Common Stock stated as issued and outstanding
in such certificate shall be approximately 11,989,587 shares, plus the Purchased
Shares and no shares of Preferred stock shall be stated as issued and
outstanding.

      6. Conditions of the Company's Obligations at Closing. The obligations of
the Company to Investor under this Agreement are subject to the fulfillment on
or before the Closing of each of the following conditions by Investor:

            6.1 Representations and Warranties. The representations and
warranties of Investor contained in Section 4 and in the Related Agreements
shall be true on and as of the Closing with the same effect as though such
representations and warranties had been made on and as of the Closing.

            6.2 Performance. The Company shall have performed and complied with
all agreements, obligations and conditions contained in this Agreement and the
Related Agreements that are required to be performed or complied with by it on
or before the Closing.

            6.3 Compliance Certificate. An officer of Paradyne shall deliver to
the Company at the Closing a certificate stating that the conditions specified

            6.4 Qualifications. All authorizations, approvals, or permits, if

as of the Closing.

            6.5 Execution of Technology Agreements. Investor shall have duly
executed and delivered the Related Agreements.

      7. Covenants of the Company

            7.1 Shelf Registration.

                  (a) As soon as reasonably practicable after the Closing, the
Company shall prepare and file a registration statement with the SEC under the
Securities Act to register the resale of the Purchased Shares ("Registrable
Securities") and thereafter shall use its best efforts to secure the
effectiveness of such registration statement as soon as reasonably practicable
within one hundred twenty (120) days after the Closing. Notwithstanding the
foregoing, if ABI shall provide a certificate of its President or other
corporate officer to Paradyne (i) stating that ABI is continuing to diligently
attempt to secure the effectiveness of such registration statement as soon as
reasonably practicable and (ii) explaining the reasons why ABI cannot secure the
effectiveness of such registration statement within one hundred twenty (120)


                                       7
<PAGE>   11
days after the Closing, then ABI's covenant to secure the effectiveness of such
registration statement as provided in this Section 7.1 shall be extended to not
more than one hundred eighty (180) days after the Closing so long as ABI
continues to diligently use its best efforts to secure the effectiveness of such
registration statement as soon as reasonably practicable.

                  (b) The Company shall pay all Registration Expenses (as
defined below) in connection with any such registration or any other
registration, qualification or compliance hereunder, and each holder of
Registrable Securities ("Holder") shall pay all Selling Expenses (as defined
below) and other expenses that are not Registration Expenses relating to the
Registrable Securities resold by such Holder. "Registration Expenses" shall mean
all expenses, except for Selling Expenses, incurred by the Company in complying
with the registration provisions herein described, including, without
limitation, all registration, qualification and filing fees, printing expenses,
escrow fees, fees and disbursements of counsel for the Company, blue sky fees
and expenses and the expense of any special audits incident to or required by
any such registration. "Selling Expenses" shall mean all selling commissions,
underwriting fees and stock transfer taxes applicable to the Registrable
Securities and all fees and disbursements of counsel for any Holder.

                  (c) In the case of any registration effected by the Company
pursuant to these registration provisions, (x) the Company will use its best
efforts to: (i) keep such registration effective until the later of (A) twelve
(12) months after the Closing Date or (B) such date as the Company shall be
satisfied that the then-current Holders may sell all of the Registrable
Securities then held by each such Holder within a single three (3) month period;
(ii) 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; (iii) furnish such number of prospectuses and other
documents incident thereto, including any amendment of or supplement to the
prospectus, as a Holder from time to time may reasonably request; (iv) use its
best 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 (up to 5 such jurisdictions),
provided 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; (v) cause all such
Registrable Securities registered as described herein to be listed on each
securities exchange and quoted on each quotation service on which similar
securities issued by the Company are then listed or quoted; (vi) provide a
transfer agent and registrar for all Registrable Securities registered pursuant
to such registration statement and a CUSIP number for all Registrable
Securities; and (vii) otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC and (y) the Holders, severally,
shall promptly provide to the Company (and in any event within 10 days of
receipt of the written request therefor) all written information regarding the
Holders and the Registrable Securities as the Company shall reasonably request
and as is required to be included in the Registration Statement with respect to
the Holders.


                                       8
<PAGE>   12
                  (d) The right to sell Registrable Securities pursuant to the
registration statement described herein will automatically be assigned to each
transferee of Registrable Securities (subject to Section 9.2 hereof). In the
event that it is necessary, in order to permit a Holder to sell Registrable
Securities pursuant to the Company's registration statement, to amend the
registration statement to name such Holder, such Holder shall, upon written
notice to the Company, be entitled to have the Company make such amendment as
soon as reasonably practicable. Notwithstanding the above provisions relating to
Registration Expenses, in the event that such an amendment is requested the
Holder shall, at the request of the Company, be obligated to reimburse the
Company for reasonable Registration Expenses incurred by it in connection with
such amendment.

                  (e) 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 Registrable
Securities to the public without registration or pursuant to a registration on
Form S-3, the Company hereby covenants and agrees to use its best efforts to:
(i) make and keep public information available, as those terms are understood
and defined in Rule 144, at all times after the closing; (ii) file with the SEC
in a timely manner all reports and other documents required of the Company under
the Securities Act and Exchange Act; and (iii) furnish to any Holder, as long as
the Holder owns any Registrable Securities forthwith upon request, (A) a written
statement by the Company that it has complied with the reporting requirements of
Rule 144, the Securities Act and the Exchange Act, (B) a copy of the most recent
annual or quarterly report of the Company, and (C) such other information as may
be reasonably requested in order to avail any Holder of any rule or regulation
of the SEC that permits the selling of any such Registrable Securities without
registration or pursuant to such Form S-3.

            7.2 Piggyback Registration. For the period from the Closing until
the registration statement provided for in Section 7.1(a) hereof shall become
effective, and thereafter during any period that ABI is required to keep such
registration statement effective and such registration statement is not
effective, if (but without any obligation to do so) the Company proposes to
register (including for this purpose a registration effected by the Company for
stockholders other than Investor) 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, a registration on any form which is not
available for the resale of the Registrable Securities, a registration statement
on Form S-4 or any successor form, or a registration in which the only Common
Stock being registered is Common Stock issuable upon conversion of debt
securities which are also being registered), the Company shall, at such time,
promptly give each Holder written notice of such registration. Upon the written
request of any Holder given within ten (10) days after mailing of such notice by
the Company, the Company shall cause to be registered under the Securities Act
all of the Registrable Securities that each such Holder has requested to be
registered. In connection with any such registration which involves the
underwritten offering of the Company's securities, the Company shall not be
required to include any Holder's securities under such registration statement
unless such Holder agrees to enter into an underwriting agreement in the form
agreed upon between the Company and the underwriters selected by it (or


                                       9
<PAGE>   13
by other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, requested by stockholders to be
included in such offering exceeds the amount of securities sold other than by
the Company that the underwriters determine in their sole discretion is
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of such securities, including
Registrable Securities, which the underwriters determine in their sole
discretion will not jeopardize the success of the offering (the securities so
included to be apportioned pro rata among the selling stockholders according to
the total amount of securities entitled to be included therein owned by each
selling stockholder or in such other proportions as shall mutually be agreed to
by such selling stockholders).

            7.3 Indemnification.

                  (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, any underwriter (as defined in the Securities
Act) for such Holder, its officers, directors, shareholders or partners and each
person, if any, who controls such Holder or underwriter 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 other federal or state law, 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"): (A) any untrue statement or alleged
untrue statement of a material fact contained in a registration statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (B) 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, or (C) 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 pay to each
such Holder (limited to Paradyne), underwriter or controlling person, as
incurred, any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the indemnity agreement contained in this
Section 7.3(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 (which consent shall not be unreasonably withheld), 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, underwriter or controlling person.

                  (b) To the extent permitted by law, each selling Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Securities Act, any underwriter,
any other Holder selling securities in such registration statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing


                                       10
<PAGE>   14
persons may become subject, under the Securities Act, the Exchange Act or over
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 pay, as incurred, any legal or other expenses reasonably incurred by
any person intended to be indemnified pursuant to this Section 7.3(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this Section 7.3(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 Holder, which consent shall not be unreasonably withheld;
provided, that, in no event shall any indemnity under this Section 7.3(b) exceed
the net proceeds from the offering received by such Holder, expect in the case
of willful fraud by such Holder.

                  (c) Promptly after receipt by an indemnified party under this
Section 7.3(c) 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 7.3(c), deliver
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
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the reasonable fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if materially prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 7.3(c), but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 7.3(c).

                  (d) If the indemnification provided for in this Section 7 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
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 statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations; provided, that, in no event shall any contribution by a Holder
under this Section 7.3(d) exceed the net proceeds from the offering received by
such Holder, except in the case of willful fraud by such Holder. The relative
fault of the indemnifying party and of the indemnified party shall be determined
by reference to, among over things, whether the untrue or alleged


                                       11
<PAGE>   15
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

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

            7.4 Participation Right. Subject to the terms and conditions
specified in this Section 7.4, the Company hereby grants to Investor a right to
participate with respect to future sales by the Company of its Shares (as
hereinafter defined); provided that such sale is: (i) at a per share price at or
below $3.375 (as adjusted for any stock splits, dividends, combinations,
reclassifications or the like) and (ii) not a public sale effected through an
underwriter, broker or dealer in a market transaction. Subject to the foregoing,
each time during the thirty (30) month period beginning on the Closing Date that
the Company proposes to offer any shares of, or securities convertible into or
exercisable for, any shares of any class of its capital stock ("Shares"), the
Company shall first make an offering of such Shares to Investor in accordance
with the following provisions:

                  (a) the Company shall deliver a notice by certified mail
("Notice") to Investor stating (i) its bona fide intention to offer such Shares,
(ii) the number of such Shares to be offered, (iii) the price and terms, if any,
upon which it proposes to offer such Shares and (iv) the number of Shares that
Investor has the right to purchase under this Section 7.4.

                  (b) By written notification received by the Company, within 5
business days after giving of the Notice, Investor may elect to purchase or
obtain, at the price and on the terms specified in the Notice, up to that
portion of such Shares that equals the proportion that the number of shares of
Common Stock issued and held by Investor bears to the total number of shares of
Common Stock of the Company then outstanding (assuming full conversion and
exercise of all convertible or exercisable securities). Any such election shall
be irrevocable written notice with respect to such offer only and failure to
give such notice within such time period shall be an irrevocable waiver of such
election right with respect to such offer only.

                  (c) If all Shares which Investor is entitled to obtain
pursuant to Section 7.4 are not elected to be obtained, then the Company may,
during the 90-day period following the expiration of the period provided in
Section 7.4(b) hereof, offer the remaining unsubscribed portion of such Shares
to any person or persons at a price not less than, and upon terms no more
favorable to the offeree than those specified in the Notice. If the Company does
not enter into an agreement for the sale of the Shares within such period, or if
such agreement is not consummated within 90 days of the execution thereof, the
right provided hereunder shall be deemed to be revived and such Shares shall not
be offered unless first reoffered to Investor in accordance herewith.


                                       12
<PAGE>   16
                  (d) The participation right in this Section 7.4 shall not be
applicable (i) to the issuance or sale of shares of common stock (or options
therefor) to employees, consultants or directors of the Company for the primary
purpose of soliciting or retaining their employment or services and (ii) to the
issuance of securities pursuant to the conversion or exercise of convertible or
exercisable securities, provided the convertible or exercisable securities (if
issued after the date hereof) were subject to or exempt from the right of
participation set forth herein.

      8. Covenants of Investor

            8.1 Company Purchase Right. For the twenty four (24) month period
beginning on the Closing Date, (i) if the Company's Common Stock shall continue
to be designated for listing on the Nasdaq National Market and (ii) if Holder
shall propose to sell Registrable Securities in a public market transaction
effected through a market maker in such stock on the Nasdaq National Market (not
including any managed or otherwise negotiated sale), then Holder shall notify
the Company by telephone or facsimile (addressed to the Chief Financial Officer
of the Company, which notice shall be deemed to be effective upon transmission
thereof) of its intent to do so at least two (2) full trading days prior to such
sale. Within such two (2) day period, the Company or such party as the company
may designate, subject to Investor's approval which shall not be unreasonably
withheld, shall have the right to purchase such Registrable Securities (by
irrevocable delivery of the purchase price therefor) at a purchase price equal
to the highest reported sale price for the Company's Common Stock on the Nasdaq
National Market during such two (2) day period.

            8.2 Limitation on Sale. Unless waived by the Company, Investor
hereby agrees that it shall not, directly or indirectly sell, offer to sell,
contract to sell (including, without limitation, any short sale), grant any
option to purchase or otherwise transfer or dispose of (other than to

                                EMPLOYMENT AGREEMENT

        THIS EMPLOYMENT AGREEMENT is entered into as of the 18th day of
November, 1996, between Access Beyond, Inc., a Delaware corporation
("Employer"), and Ronald A. Howard ("Employee").

                                     WITNESSETH:

        WHEREAS, Employer and Employee desire to enter into this Employment
Agreement to insure Employer of the services of Employee and to set forth the
rights and duties of the parties hereto.

        NOW, THEREFORE, in consideration of the mutual promises herein
contained, the parties agree as follows:

        1.      Employment and Duties.

                (a)     Employer hereby employs Employee, and Employee hereby
        accepts such employment, upon the terms and conditions hereinafter set
        forth. Employee shall serve as Chairman of the Board, President and
        Chief Executive Officer of Employer, and in such substitute or further
        offices or positions with Employer or any subsidiary of Employer as
        shall, from time to time, be assigned by the Board of Directors of
        Employer (the "Board"), without, however, any change in Employee's
        compensation hereunder (but such office or positions shall be consistent
        with such office or position hereinbefore named). To the extent that the
        Board shall request, during the term of this Agreement, Employee shall
        serve as a member of the Board or as a member of the board of directors
        of any subsidiary of Employer.

                (b)     During the term of this Employment Agreement, Employee
        will devote substantially all of his working time and best efforts to
        his employment and perform diligently such duties as are or may be from
        time to time required by the Board, which duties shall be

<PAGE>   2
consistent with his position as set forth above. Employee shall not, without
the prior written consent of Employer, directly or indirectly, during the term
of this Employment Agreement, (i) other than in the performance of duties
naturally inherent in the businesses of Employer or any subsidiary of Employer
and in furtherance thereof, render services of a business, professional or
commercial nature to any other person or firm, whether for compensation or
otherwise; provided, however, that this shall not be construed as preventing
Employee from (1) investing his assets in such form or manner as will not
require the rendering of any services on his part to the companies in which
such investments are made and which are not in violation of Subsection (ii)
below, or (2) engaging in charitable activities or rendering services to any
business entity of a business, professional or commercial nature, as a
consultant, independent contractor or otherwise, so long as such activities do
not materially interfere with the performance of Employee's duties hereunder
and are not in violation of Subsection (ii) below; (ii) engage in any activity
competitive with or adverse to Employer's business or welfare, whether alone,
as a partner, or as an officer, director, employee or shareholder of any other
corporation, or otherwise, directly or indirectly, except that the ownership of
not more than one percent (1%) of the stock of any publicly traded corporation
shall not be deemed violative of this Subsection (ii); and (iii) be engaged by
any entity which conducts business with or acts as consultant or advisor to
Employer, whether alone, as a partner, or as an officer, director, employee or
shareholder, or otherwise, directly or indirectly, except that the ownership of
not more than one percent (1%) of the stock of any publicly traded corporation
shall not be deemed violative of this Subsection (iii). For purposes of this
Employment Agreement, all references herein to subsidiaries of Employer shall
be deemed to include references to subsidiaries now or hereafter existing.

<PAGE>   3
        2.      Term.  Subject to the provisions for termination as hereinafter
provided, the term of this Employment Agreement shall be deemed to begin on the
date hereof, and shall continue for a term of two (2) years from such date to
and including November 17, 1998.

        3.      Compensation.

                (a)  For all services he may render to Employer (and any
        subsidiary of Employer) during the term of this Employment Agreement,
        Employee shall receive from Employer an aggregate base salary while he
        is employed hereunder at the rate of One Hundred Seventy-Five Thousand
        Dollars ($175,000) per year, payable in accordance with the executive
        payroll schedule in effect at Employer from time to time.

                (b)  In addition to the base salary compensation as above
        stated, Employee shall be named a participant in, and shall be entitled
        to be eligible to receive amounts awarded him under any formal or
        informal bonus plan adopted by Employer for Employee or for its
        executives generally during the term of this Employment Agreement, which
        shall be determined and paid in a manner consistent with the terms of
        such plan, provided that the same may include individual goals
        commensurate with Employee's duties and responsibilities, as determined
        by the Board, or a committee designated thereby. Each such payment shall
        be conditioned on Employee being employed by Employer at the end of the
        period for calculating such bonus; provided that in the event that
        Employee's employment by Employer is terminated by reason of his death
        or permanent disability or by Employer other than for "cause", such
        bonus payment shall be made to Employee or his estate, as the case may
        be, on a pro rata basis, determined by reference to the number of days
        from the beginning of the period for calculating such bonus to the date
        of such termination as compared to the total number of days in such
        year.

beneficiaries designated by Employee being in the amount of not less than Five

hospitalization benefits, automobile and mobile telephone allowance and such
other similar employment benefits as are afforded other company senior
executives, from time to time. If not otherwise within such benefits, Employer
will provide Employee with benefits, pursuant to a plan or otherwise, which
pays, or reimburses Employee for, all out-of-pocket and other medical expenses
of Employee and his dependents.

        5. New Option. Effective immediately upon entering into this Employment
Agreement, Employer shall cause Employee to be granted the option to purchase

Agreement and Employee's employment with Employer for cause on immediate notice
in writing upon the occurrence of any of the following events:

             (i) Employee's conviction in a court of law of any crime or offense

     involving moral turpitude in the jurisdiction involved;

             (ii) Employee's willful misconduct or gross negligence which has

goals to be achieved after such termination shall be deemed to be achieved) for
the remaining term of this Employment Agreement.

     (d) During absence from work by reason of incapacity through ill health or
injury, Employee will be entitled to be paid a normal salary rate for each day
of absence for up to 90 working days (whether continuous or in the aggregate)
during any consecutive period of 12 months. Thereafter, Employee will be
compensated pursuant to such disability insurance plan as Employer may then have
in effect and applicable law.

8.  Change of Control

     (a)  In the event that there is a "Change in Control" of Employer, Employee
shall be paid in lump sum two and one-half times an amount equal to Employee's
previous full year compensation, including bonus, if any.

          A "Change in Control" shall mean a change in control of Employer of a
nature that would be required to be reported in response to Item 6(e) of
Schedule 14A of Regulation 14A promulgated under the Securities Exchange Act of
1934 (as in effect on the date of this Employment Agreement, the "Exchange
Act"), whether or not Employer is then subject to such reporting requirement;
provided that, without limitation, such a Change in Control shall 

                                          6
<PAGE>   7
be deemed to have occurred if after the distribution of Employer's common stock 
by Penril DataComm Networks, Inc. ("Penril") to the stockholders of Penril:

                (i)     any "person" (as defined in subsections 13(d) and 14(d) 
        of the Exchange Act), is or becomes the "beneficial owner" (as defined 
        in Rule 13d-3 under the Exchange Act), directly or indirectly, of 
        securities of Employer representing thirty percent (30%) or more of the 
        combined voting power of Employer's then outstanding securities;

                (ii)    during any period of two (2) consecutive years or less 
        there shall cease to be a majority of the Board comprised of Continuing
        Directors (as defined below); or

                (iii)   the stockholders of Employer approve (1) a merger or
        consolidation of Employer with any other corporation, other than a
        merger or consolidation that would result in the voting securities of
        Employer outstanding immediately prior thereto continuing to represent
        (either by remaining outstanding or by being converted into voting
        securities of the surviving entity) at least 80% of the combined voting
        power of the voting securities of Employer or such surviving entity
        outstanding immediately after such merger or consolidation, or (2) a
        plan of complete liquidation of Employer or an agreement for the sale or
        disposition by Employer of all or substantially all of its assets.

        The term "Continuing Directors" shall mean individuals who constitute
the Board as of the date of this Employment Agreement and any new director(s)
whose election by such Board or nomination for election by Employer's
stockholders was approved by a vote of at least two-thirds of the directors
then in office who either were directors as of the date of this

                                          7

<PAGE>   8
Employment Agreement or whose election or nomination for election was
previously so approved.

        (b)     If the firm of independent outside auditors used by Employer
(the "Auditors") determine that any payment or distribution by Employer to or
for the benefit of Employee, whether paid or payable (or distributed or
distributable) pursuant to the terms of this Section 8 or otherwise, would be
subject to tax as a golden parachute payment for federal income tax purposes
pursuant to the provisions of section 4999 of the Internal Revenue Code of
1986, as amended (the "Code"), then the aggregate present value of the amounts
payable or distributable to or for the benefit of Employee pursuant to this
Agreement shall be reduced (but not below zero) to the Reduced Amount. For
purposes of this Section 8, the "Reduced Amount" shall be an amount expressed
in present value that maximizes the aggregate present value of payments that
can be made to Employee without causing any payment to be subject to tax
pursuant to section 4999 of the Code.

        (c)     If the Auditors determine that any payment would be subject to
tax under section 4999 of the Code, then Employer shall promptly give Employee
notice to that effect and a copy of the detailed calculation thereof. Employee
may then elect, in his sole discretion, which and how much of the payment shall
be eliminated or reduced (as long as after such election the aggregate present
value of the payments equals the Reduced Amount) and shall advise Employer in
writing of his election within twenty (20) days of his receipt of notice. If no
such election is made by Employee within such twenty (20) day period, then
Employer may elect which and how much of the payments shall be eliminated or
reduced (as long as after such election the aggregate present value of the
payments equals the Reduced Amount) and shall notify Employee promptly of such
election. For purposes of this Section 8, present

                                          8
<PAGE>   9
        value shall be determined in accordance with section 280G(d)(4) of the
        Code (or any successor provision). All determinations made by the
        Auditors shall be subject to arbitration under this Agreement and shall
        be made within 60 days of Employee's termination of employment. As
        promptly as practicable following such determination and the elections
        hereunder, Employer shall pay to or distribute to Employee the amounts
        required to be paid to him.

        9.      Reimbursement. Employer shall reimburse Employee during the
term of this Employment Agreement for travel, entertainment and other expenses
reasonably and necessarily incurred by Employee in the promotion of Employer's
business and the performance of Employee's duties hereunder, all in accordance
with Employer's then current policy. Employee shall submit to Employer
appropriate written periodic statements of all expenses so incurred, together
with such other substantiation as Employer may reasonably request.

        10.     Intellectual Property. Employee acknowledges and agrees that
Employer shall be and remain the sole owner of all the fruits and proceeds of
Employee's services hereunder, including, but not limited to, all ideas,
inventions, concepts, developments, discoveries, whether or not protectable,
and other properties which Employee may create or conceive in connection with,
and during the term of, Employee's employment hereunder, free and clear of any
claims by Employee (or any successor or assignee of Employee) of any kind or
character whatsoever other than Employee's right to compensation hereunder.
Employee agrees that he shall, at the request of the Board, execute such
assignments, certificates or other instruments as the Board may from time to
time deem necessary or desirable to evidence, establish, maintain, perfect,
protect, enforce or defend the Employer's right, title and interest in or to
any such properties.

11.  Covenants and Confidential Information.

     (a) Employee agrees that during the term of this Employment Agreement and
(1) for a period of two (2) years thereafter if Employee's employment is
terminated for cause, and (2) as to clause (iv) of this Subsection (a), at any
time after the term of this Employment Agreement, he will not, directly or
indirectly, do or suffer any of the following:

          (i) Own, manage, control or participate in the ownership, management,
     or control of, or be employed or engaged by or otherwise affiliated or
     associated as a consultant, independent contractor or otherwise with, any
     other corporation, partnership, proprietorship, firm, association, or other
     business entity, or otherwise engage in any business, which competes with
     the business of Employer or any of Employer's affiliated or subsidiary
     corporations (as conducted on the date Employee ceases to be employed by
     Employer in any capacity, including as a consultant); provided, however,
     that the ownership of not more than one percent (1%) of the stock of any
     publicly traded corporation shall not be deemed a violation of this
     covenant; and, provided further, that employment by a division of a
     corporation which corporation competes with the business of Employer shall
     not be deemed to be a violation of this covenant as long as such division
     does not compete with the business of Employer or any of Employer's
     affiliated or subsidiary corporations and as long as Employee does not
     render services or assistance to such corporation or to divisions or
     affiliated or subsidiary corporations of such corporation which services or
     assistance is involved in or facilitates such business which competes with
     the business of Employer or any of Employer's affiliated or subsidiary
     corporations.

<PAGE>   11
                (ii)   Employ, assist in employing, or otherwise associate in
        business with any present or former or future employee or officer of
        Employer or any of Employer's affiliated or subsidiary corporations.

                (iii)  Induce any person who is an employee or officer of
        Employer or any of Employer's affiliated or subsidiary corporations to
        terminate said relationship.

                (iv)   Disclose, divulge, discuss, copy or otherwise use in any
        manner, in competition with, or contrary to the interests of, Employer
        or any of Employer's affiliated or subsidiary corporations, the customer
        lists, manufacturing methods, product research or engineering data or
        other trade secrets of Employer or any of Employer's affiliated or
        subsidiary corporations, it being acknowledged by Employee that all such
        information regarding the business of Employer and Employer's affiliated
        or subsidiary corporations compiled or obtained by, or furnished to,
        Employee while Employee shall have been employed by or associated with
        Employer is confidential information and Employer's exclusive property.

        (b)  Employee expressly agrees and understands that the remedy at law
for any breach by him of this Section 11 will be inadequate and that the damages
flowing from such breach are not readily susceptible to being measured in
monetary terms. Accordingly, it is acknowledged that upon adequate proof of
Employee's violation of any legally enforceable provision of this Section 11,
Employer shall be entitled to immediate injunctive relief and may obtain a
temporary order restraining any threatened or further breach. Nothing in this
Section 11 shall be deemed to limit Employer's remedies at law or in equity for
any breach by Employee of any of the provisions of this Section 11 which may be
pursued or availed of by Employer.

<PAGE>   12
          (c)   In the event Employee shall violate any legally enforceable
     provision of this Section 11 as to which there is a specific time period
     during which he is prohibited from taking certain actions or from engaging
     in certain activities, as set forth in such provision, then, in such event,
     such violation shall toll the running of such time period from the date of
     such violation until such violation shall cease.
        
          (d)   Employee has carefully considered the nature and extent of the
     restrictions upon him and the rights and remedies conferred upon Employer
     under this Section 11, and hereby acknowledges and agrees that the same are
     reasonable in time and territory, are designed to eliminate competition
     which otherwise would be unfair to Employer, do not stifle the inherent
     skill and experience of Employee, would not operate as a bar to Employee's
     sole means of support, are fully required to protect the legitimate
     interests of Employer and do not confer a benefit upon Employer
     disproportionate to the detriment to Employee. The provisions of this
     Section 11 shall survive the termination of this Employment Agreement.

     12.   Severable Provisions. The provisions of this Employment Agreement are
severable and if any one or more provisions may be determined to be illegal or
otherwise unenforceable, in whole or in part, the remaining provisions and any
partially unenforceable provision to the extent enforceable in any jurisdiction
shall, nevertheless, be binding and enforceable.

     13.   Binding Agreement. The rights and obligations of Employer under this
Employment Agreement shall inure to the benefit of, and shall be binding upon,
Employer and its successors and assigns, and the rights and obligations of
Employee under this Employment Agreement shall inure to the benefit of, and
shall be binding upon, Employee and his heirs, personal representatives and
estate.

     14.   Notices. Any notice to be given under this Employment Agreement shall
be personally delivered in writing or shall have been deemed duly given when
received after it is posted in the

of business, attention: Secretary, and if mailed to Employee, shall be
addressed to him at his home address last known on the records of Employer, or
at such other address or addresses as either Employer or Employee may hereafter
designate in writing to the other.

        15. Waiver. The failure of either party to enforce any provision or
provisions of this Employment Agreement shall not in any way be construed as a
waiver of any such provision or provisions as to any future violations thereof,
nor prevent that party thereafter from enforcing each and every other
provision of this Employment Agreement. The rights granted the parties herein
are cumulative and the waiver of any single remedy shall not constitute a waiver
of such party's right to assert all other legal remedies available to it under
the circumstances.

        16. Governing Law. This Employment Agreement shall be governed by and
construed according to the laws of the State of Maryland.

        17. Captions and Section Headings. Captions and Section headings used

termination or attempted waiver shall be valid unless in writing and signed by
the party against whom the same it is sought to be enforced. Where necessary or

          4.1 Firm Orders; Forecasts. AB will provide to Hibbing firm purchase
orders for a minimum of three (3) months in advance of delivery. Further, AB
will submit a rolling six (6) month non-binding forecast to be updated monthly.
This release and forecast will identify quantity, part numbers, and expected
delivery dates for Products AB expects to order during the forecast period in
order that Hibbing may plan production and procure components for purchase
orders and the forecast period. Long lead items or allocated components, beyond
the three (3) month firm purchase order period or beyond the six (6) month
forecast, are to be covered by a separate written authorization from AB.

          4.2 Rescheduling. AB may reschedule Product delivery dates on orders
that are due more than sixty (60) calendar days from the date such change notice
is provided to Hibbing. Additional rescheduling of Products may only be made
with the mutual agreement of the parties. AB agrees to pay reasonable carrying
charges agreed to by it in the event of any such additional reschedulings.

          4.3 Material List. Hibbing will provide a list of materials with
lead-time greater than four (4) weeks that will be ordered to support AB's three
(3) month purchase order release window and the six (6) month forecast period.
AB will have liability for all material procured to support these firm purchase
orders and all material procured pursuant to the separate written authorizations
from AB contemplated by Section 4.1., in the event of cancellation, schedule
changes, or termination. However, Hibbing will use reasonable commercial efforts
to mitigate such liability.

          4.4 Cancellation. AB may, for reasonable cause, reduce or cancel
quantities of Products. AB agrees to pay reasonable cancellation and carrying
charges. These charges may include the purchase price of all undelivered
finished goods, costs of work in process, components and materials on hand and
nonreturnable or noncancelable from suppliers, and any amortized start-up, test
or tooling costs.

respect to any Products that Hibbing hand delivers, title and risk of loss will

                                   INSPECTION

          7.1 Inspection. All Products may be inspected and tested by AB and its
customers at all reasonable times and places on a noninterference basis. If such
inspection or testing is made on Hibbing's premises, including without
limitation the premises described in Article 16 hereof, Hibbing shall provide
(at AB's expense) all reasonable facilities and assistance for such inspections
and tests. In its internal inspection and testing of the Products, Hibbing shall
use an inspection system mutually agreed upon by the parties in writing. All
inspection records relating to the Products shall be available to AB during the
performance of this Agreement upon reasonable request.

          7.2 Final Inspection. Final inspection and acceptance by AB shall be
at destination unless otherwise specified in a particular order. Such inspection
shall be in accordance with AB's customary inspection procedures at the location
where the Products are received.

          7.3 Effect of Inspection. No inspection (including source inspection)
tests, approval (including design approval), or acceptance of the Products shall
relieve Hibbing from responsibility for Hibbing's warranty obligations under
Article 10 of this Agreement.

                                 PRICE - PAYMENT

          8.1 Price.

                  (a) In each three (3) calendar month period during the term of
this Agreement, Hibbing shall sell the first $2.8 million of Products delivered
to AB (the "Cost Products") at a price determined under Hibbing's pricing model
for the Products taking into account materials, direct labor, manufacturing
overhead, selling, general and administrative costs, and interest in accordance
with Hibbing's customary internal cost allocation procedures, exclusive of a
profit margin component. The initial Cost Products price list is set forth in
Schedule 8.1(a)-I attached hereto and made part hereof. Hibbing reserves the
right to change the price of Cost Products at any time, but only to reflect
changes in the costs of the elements of its pricing model or in the prices or
amounts of the underlying inputs for the Products. Hibbing's pricing model is
attached as Schedule 8.1(a)-II. Hibbing shall give notice to AB of any price
change for Cost Products at least thirty (30) calendar days prior the effective
date of such change and such price change shall apply only to orders placed
after the effective date thereof; provided, however, the amount and timing of
any price changes with respect to market fluctuations in the costs of materials
attributable to allocation, availability or obsolescence must be mutually agreed
upon by the parties. Such notice shall provide sufficient detail to permit audit
by AB of the identifiable costs of manufacture of the Products. If in the first
three (3) calendar month period during the term of this Agreement, AB orders
less than $2.8 million in Cost Products, the difference shall be equally divided
among the five (5) succeeding three (3) calendar month periods during the term
of this Agreement and the resulting amount shall increase the amount of Cost
Products available for purchase by AB during each such period.

                  (b) Products sold by Hibbing to AB in any three (3) calendar
month period during the term of this Agreement (the first such period to
commence on the effective date of this Agreement) in excess of the Cost Products
shall be sold at the prices listed on Schedule 8.1(b) annexed hereto and made
part hereof. The price to be paid for all Products delivered hereunder in excess
of the Cost Products will be the price of the Cost Products plus Hibbing's
eleven and 36/100 percent (11.36%) profit margin component. Hibbing reserves the
right to change such price list at any time, provided, however, that Hibbing
shall give notice of any price change to AB at least thirty (30) calendar days
prior to the effective date of such change, and such price change shall apply
only to orders placed after the effective date hereof; provided, however, that
the amount and timing of any price changes with respect to market fluctuations
in the costs of materials attributable to allocation, availability or
obsolescence must be mutually agreed upon by the parties.

                  (c) It is AB's intention during the term of this Agreement to
procure its printed circuit board requirement from Hibbing. However, AB reserves
the right to purchase products, comparable to the Products, from alternate
suppliers in the event that there exists a strategic benefit for AB to do so
(including, without limitation, Hibbing's decision to change its price model as
permitted under subsection 16.13(d)) or in the event that AB is required by a
customer to utilize an alternate supplier. AB also reserves the right to
purchase products from an alternate supplier in the event that Hibbing's supply
of Products or Product quality fail to meet AB's standards and requirements.

                  (d) If Hibbing realizes a reduction in total material cost of
a Product (other than with respect to the costs of materials purchased under
Hayes contracts), fifty percent (50%) of such reduction shall be passed on to AB
in the form of a cost reduction on future orders of that same Product.

          8.2 Payment. AB shall pay to Hibbing any and all amounts due for the
purchase of Products within thirty (30) calendar days of the date of Hibbing's
invoice, which shall be dated no earlier than the date upon which the Product so
involves is first provided (if such Product consists of services) or is
delivered to a common carrier by Hibbing pursuant to this Agreement or hand
delivered, provided that in no event shall payment be due prior to receipt of
the Product.

          8.3 Records: Audit Rights.

                  (a) Hibbing shall maintain for three (3) years following the
close of each calendar year accurate books and records which disclose all
pricing model information with respect to the Products.

                  (b) AB, at its expense, shall have the right at any time
during regular business hours, upon thirty (30) days' prior notice to Hibbing,
to examine or audit the books and accounts and records of Hibbing which pertain
to the manufacture of Products. Such books of account and records shall be made
available to AB and its accountants at the location where such books and records
are regularly maintained by Hibbing. If the examination or audit reveals an
apparent overcharge, and the parties cannot agree to a satisfactory resolution,
then the matter will be submitted to binding arbitration by a single arbitrator
experienced in financial accounting matters in Gaithersburg, Maryland
administered by the American Arbitration Association under its Commercial
Arbitration Rules then in effect, and judgment on the award rendered by the
arbitrator may be entered in any court having competent jurisdiction. The
arbitrator may award fees and expenses as part of the decision.

benefit of creditors, files a petition in bankruptcy, is adjudicated bankrupt or
insolvent, petitions or applies for a receiver or a trustee, or has any
proceedings commenced against it under any statute or regulation providing
bankruptcy, reorganization, arrangement, readjustment of debt, dissolution or
liquidation and which remain undischarged for a period of sixty (60) calendar
days.

a party may be entitled by reason of such rights (including, without limitation,
Hibbing's rights to be paid for rescheduling and cancellation charges pursuant

Agreement, all obligations of the parties hereunder shall terminate, except
those which expressly survive the termination or expiration of this Agreement.

          9.4 Remedies. In the event of a breach of this Agreement, the
nonbreaching party may exercise any remedy allowed by law or equity; provided,
however, AB will not have the right to effect cover or the right of setoff. AB's
remedies shall be cumulative and except as provided herein, remedies herein

                               LIMITED WARRANTIES

          10.1 Limited Warranty. Hibbing warrants that all Products will upon
delivery to Hibbing's designated shipping point, USA, or upon hand delivery and
for a period of fifteen (15) calendar months thereafter: (i) be free from
defects in materials and workmanship; (ii) materially conform to the design,
specifications and drawings provided by AB; and (iii) conform to IPC 610 class
2. These warranties shall survive any inspection, delivery, acceptance and
payment.

          10.2 Liability. Hibbing's liability under this warranty provision is
limited to (i) repair or replacement at Hibbing's option without cost to AB of
the defective Product or (ii) delivery of retrofit kits with installation
instructions (at no charge to AB) as necessary to make the Product conform to
AB's specifications; in each case, solely during the fifteen (15) calendar month
period following delivery of the Product to Hibbing's designated shipping point,
USA or hand delivery. Labor to remove defective parts and install replacement
parts under this limited warranty must be mutually agreed upon by Hibbing and
AB. If the parties are unable to reach agreement regarding the amount of cost of
labor described in the preceding sentence, then the matter will be submitted to
binding arbitration by a single arbitrator experienced in financial accounting
matters in Gaithersburg, Maryland administered by the American Arbitration
Association under its Commercial Arbitration Rules then in effect, and judgment
on the award rendered by the arbitrator may be entered in any court having
competent jurisdiction. The arbitrator may award fees and expenses as part of
the decision.

          10.3 Warranty Claims. All warranty claims shall be made by AB,
regardless of any transfer of title or possession of the Product by AB to
customers or other parties, and AB must notify Hibbing in writing of any such
claim promptly following AB learning of any alleged breach of warranty.

          10.4 Returned Products. Returned Products will be tested by Hibbing
promptly following receipt. Compliant Products will be shipped back to AB at
AB's expense and risk of loss or damage. AB will be invoiced for such testing,
on a time and material basis, for all returned products which are in compliance.
Hibbing will remain responsible for any Products returned to Hibbing for which
AB can demonstrate breach of Hibbing's limited warranty. This warranty shall not
apply to failures of any unit caused by:

instructions as provided by Hibbing or Product specification as provided by AB
or Hibbing.

                  (b) Modifications by other than Hibbing's personnel or agent
in any way other than approved by Hibbing, provided the warranty shall not be
voided by repair or replacement of parts or the attachment of items in the
manner described in maintenance or installation instructions provided by
Hibbing.

                  (c) Repair by someone other than Hibbing's personnel or agent
or in a manner contrary to the maintenance instructions provided by Hibbing.

manufacturer.

                  (f) Design related defects.

          10.5 Agencies. Hibbing makes no general warranty of compliance to any
agency such as UL, TUV, CSA, or FDA, relating to facility, processes,
workmanship, and material acquisitions in connection with the Products.

DAMAGE TO THE PRODUCT CAUSED BY NATURAL DISASTER OR ACT OF GOD, OR BY ACTIONS OF
PARTIES OTHER THAN HIBBING. IN NO EVENT WILL HIBBING BE LIABLE FOR MORE THAN THE
DOLLAR AMOUNT OF THE PRODUCTS ORDERED UNDER THIS AGREEMENT, INCLUSIVE OF ANY
PUNITIVE, CONSEQUENTIAL, INCIDENTAL OR SPECIAL DAMAGES WHICH ARISE IN CONNECTION
WITH THE FAILURE OF OR DEFECTIVE PERFORMANCE OF ANY PRODUCT COVERED BY HIBBING'S

                  (a) Hibbing will defend, indemnify and hold harmless AB, its
successors and assigns (each an "Indemnified Person") from and against any and
all actual or threatened manner of action and actions, cause and causes of
action, suits, proceedings, liabilities, losses, damages, judgments, claims,
demands, costs and expenses, including, without limitation, attorneys' fees and
expenses and court costs, regardless of whether litigation has commenced
(collectively, an "Indemnified Claim"), which any Indemnified Person may
hereafter incur, suffer or be required to pay by reason of any actual or
threatened action, claim, suit or proceeding brought by any party against any
Indemnified Person arising out of or in connection with the performance or
nonperformance by Hibbing of its obligations under this Agreement.

                  (b) Hibbing shall secure before commencing and shall maintain
during the performance (and after performance, as hereinafter provided) of this
Agreement, Comprehensive General Liability and Property Damage Insurance,
including Products Liability provisions with minimum Bodily Injury Liability and
Property Damage limits of $1,000,000 each occurrence, naming AB as an additional
insured. Hibbing shall furnish to AB evidence of such insurance coverage in the
form of certificates of insurance. All certificates of insurance shall stipulate
that AB will be given thirty (30) calendar days written notice prior to any
change, substitution, or cancellation. The coverage afforded by each of the
aforesaid policies of insurance to be furnished by Hibbing shall continue in
full force and effect as to all losses, claims, damages or liabilities in any
way arising out of the performance or nonperformance of this Agreement,
including those arising during the warranty period.

          12.2 AB Indemnity. AB will indemnify and hold harmless Hibbing, its
successors and assigns (each an "Indemnified Person") from and against any and
all actual or threatened manner of action and actions, cause and causes of
action, suits, proceedings, liabilities, losses, damages, judgments, claims,
demands, costs and expenses, including, without limitation, attorneys' fees and
expenses and court costs, regardless of whether litigation has commenced
(collectively, an "Indemnified Claim"), which any Indemnified Person may
hereafter incur, suffer or be required to pay by reason of any actual or
threatened action, claim, suit or proceeding brought by or on behalf of AB's
customers or others against any Indemnified Person: (a) involving use of
proprietary information, infringement of patents, trademarks, copyrights or
other intellectual property rights (including, without limitation, the
Trademark), use of trade secrets, or the breach of confidentiality agreements,
to the extent that any of the foregoing is included in the AB Technology or the
Standards and Specifications or relates to the design of the Products; (b)
arising out of or in connection with any actions taken or not taken, as the case
may be, at the direction of AB (including, for example, acts taken under
subsection 2.3(b), subsections 14.3(b) and (c), and Section 15.13); (c) arising
out of or in connection with the performance or nonperformance by AB of its
obligations under this Agreement; or (d) arising out of or in connection with
the conduct by AB of its business activities on or before the effective date of
this Agreement including, without limitation, AB's performance or nonperformance
of its obligations under the Leases (as defined in Section 15.14) or the
Building Lease (as defined in Section 16.13). None of the terms in this
paragraph will be deemed to reduce Hibbing's obligations to AB pursuant to
Hibbing's limited warranty or Hibbing's performance or nonperformance of other
provisions of this Agreement.

UNDER THIS AGREEMENT, REGARDLESS OF THE FORM OF ACTION, INCLUDE ANY SPECIAL,
INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR CLAIMS FOR LOSS OF BUSINESS OR
LOSS OF PROFITS, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
POTENTIAL LOSS OR DAMAGE. THE LIABILITY OF HIBBING ARISING OUT OF THE SUPPLYING
OF ANY PRODUCT OR ITS USE, WHETHER BASED UPON WARRANTY, CONTRACT, NEGLIGENCE OR
OTHERWISE, SHALL NOT IN ANY CASE EXCEED THE ORIGINAL COST TO AB OF SUCH PRODUCT.

          12.4 Control of Action. With respect to control over the negotiation
and defense of any actual or threatened action, claim, suit or proceeding,
including, without limitation, control as to the selection of counsel and as to
whether and on what terms to settle or otherwise resolve the same (referred to
in this Agreement as "Control of the Action") which may give rise to a right of
Indemnification under Article 12 hereof, the party entitled to indemnification
(the "Indemnitee"), at its option, may either retain Control of the Action or
relinquish Control of the Action to the other party (the "Indemnitor"). In any
case, if the Indemnitee relinquishes control to Indemnitor, Indemnitor will be
obligated to indemnify as set forth in this Agreement. Notwithstanding the fact
that Control of the Action may be relinquished to Indemnitor, Indemnitor may not
settle or compromise any Indemnified Claim (even if such settlement or
compromise only requires the payment of money, as opposed to other forms of
nonmonetary consideration) without the prior written consent of Indemnitee,
which consent may be withheld with or without reason unless such settlement or
compromise only requires the payment of money and Indemnitor offers evidence to
Indemnitee, satisfactory to Indemnitor, that Indemnitor is able to make such
payment. The Indemnitee may not settle or compromise an Indemnified Claim
without the prior written consent of the Indemnitor (which consent may not be
unreasonably withheld or delayed). In the event that Indemnitee has relinquished
Control of the Action to Indemnitor, Indemnitor will fully and promptly inform
Indemnitee of all developments in, and allow Indemnitee to participate (provided
that all costs incurred by Indemnitee in such participation will be paid by
Indemnitee) in the handling of, any such actions so relinquished, and
Indemnitee, at is option may at any time upon prior written notice resume
immediate Control of the Action previously relinquished to Indemnitee (in which
case Indemnitee will not be responsible for any costs or expenses incurred).

information of Hibbing disclosed to AB or learned by AB as a consequence of or
through this Agreement, includes trade secrets, know-how and other information,

respective affiliates, directors, officers and employees to: (i) hold all
Confidential Information in the strictest confidence; (ii) not use or exploit
Confidential Information except in accordance with and as contemplated by this
Agreement nor disclose it to anyone other than authorized personnel of the other
party as required for such party's performance of this Agreement; (iii) take all
precautions necessary to safeguard the confidential nature of such Confidential
Information; (iv) keep a record of employees having access to any Confidential
Information and to have all of these employees sign a non-disclosure agreement
for the direct benefit of the other party in a form acceptable

Product or any equipment or tooling embodying the Confidential Information nor
to allow any person or entity to use it, or otherwise view or examine it, except
as otherwise provided in this Agreement.

                  (b) Upon termination of this Agreement, each Party shall,
without prior demand or request of the other party, promptly return any and all
Confidential Information in any media and all copies thereof in such party's
possession or control; provided, however, that if Hibbing exercises its option
to purchase the Equipment pursuant to Section 15.6, then Hibbing will also
thereby acquire rights to use the software used for testing purposes.

                  (c) The restrictions set forth in subsections 13.1(a) and (b)
hereof shall not apply to information that: (i) is publicly available on the
date hereof or becomes generally available other than as a result of disclosure
by such party or its employees or representatives; (ii) becomes available from a
source other than such party or its employees or representatives, provided that
source is not bound by confidentiality restrictions (and such party has made
reasonable inquiry with respect thereto); (iii) was in the possession of such
party prior to its disclosure by the other party; or (iv) is approved in writing
for public disclosure by such party.

                  (d) The parties' obligations under this Article 13 shall
survive termination of this Agreement. The parties agree that breach of this
Article 13 shall cause irreparable harm and shall entitle the other party, in
addition to any other remedies it may have, to obtain injunctive relief and/or
specific performance.

of this Agreement and on the terms and conditions set forth herein, the AB
Inventory. All AB Inventory shall remain the sole and exclusive property of AB.
Hibbing agrees that it will not use AB Inventory other than in Products sold to

indirectly caused by, attributable to or relating to Hibbing's incorporation of
the AB Inventory into Products.

          14.3 Care of AB Inventory.

                  (a) The AB Inventory shall be maintained by Hibbing at AB's
premises at 1300 Quince Orchard Blvd., Gaithersburg, MD or any of Hibbing's
other locations. The AB Inventory in all cases shall be carefully segregated
from other goods either of the same or different character belonging either to
Hibbing or to any third party, shall be marked as AB's property, and shall be
stored in an area separate and not commingled with goods of Hibbing or of any
third party.

                  (b) Hibbing shall (at AB's expense) comply with all reasonable
requests and directions from AB to comply with all laws which might in any way
affect AB's ownership of AB Inventory, and shall indemnify and save harmless AB
from and against loss, damage, and expense from any levy, attachment lien, or
process involving such material arising out of Hibbing's failure to comply with
such reasonable requests and directions. Hibbing confirms that all of the AB
Inventory is, on the date hereof, present at AB's premises. Hibbing shall be
responsible for any loss or shrinkage in the

                                       11
<PAGE>   12
quantity of AB Inventory whether such loss or shrinkage be through theft,
pilferage, deterioration, or otherwise, unless such loss or shrinkage is as a
result of Hibbing's compliance with the directions or requests received from AB.

                  (c) Hibbing shall keep at all times a complete and accurate
list of the AB Inventory, copies of which list shall be furnished AB upon
reasonable request. AB's representatives shall have access to the AB Inventory
on a noninterference basis during usual business hours and with reasonable
advance notice for the purpose of verifying such inventory or inspecting the
condition of such AB Inventory.

                  (d) All public charges, whether in the nature of sales,

                  (e) To record ownership of AB Inventory, AB may from time to
time file such U.C.C. financing statements covering AB Inventory as it
determines are necessary or desirable. For such purpose, Hibbing shall (at AB's
expense) execute and deliver to AB all such U.C.C. financing statements as AB
shall from time to time request, provided that the form and content of any such
U.C.C. financing statements are reasonably acceptable to Hibbing.

          14.4 Purchase of AB Inventory.

                  (a) Without limiting the provisions of Article 9, upon
termination of this Agreement for any reason, if Hibbing has relocated the AB

Inventory at the effective date of such termination to remain in storage at
Hibbing's premises for such period as AB shall require to dispose of the same,
not exceeding thirty (30) calendar days thereafter. Hibbing shall, upon the
request and at the expense of AB, at any time or from time to time during such
thirty (30) calendar-day period, load or cause the same to be loaded on cars and

          15.1 Right to Use Equipment. AB hereby agrees to permit Hibbing to use
the personal property described on Schedule 15 and Schedule 15.14 attached
hereto and made part hereof (hereinafter, with all attachments, replacement
parts, substitutions, additions, repairs and accessories incorporated therein
and/or affixed thereto, and proceeds, referred to as "Equipment") during the
term of this Agreement. AB shall retain the right to inspect and use the
Equipment subject to the following conditions: (i) such inspection and use may
only be during usual business hours and on a noninterference basis; (ii) Hibbing
must receive reasonable advance notice (in no event less than seventy-two (72)
hours) of such inspection or use; (iii) a Hibbing employee or representative
must be present at all times during such inspection and use; and (iv) all
provisions of this Agreement applicable to Hibbing's use of the Equipment will
apply to AB's use of the Equipment (including, without limitation, an obligation
by AB to indemnify Hibbing under Section 15.15 and to maintain the Equipment
under Section 15.3).

          15.2 Use, Nature and Location of Equipment. Hibbing represents,
warrants and agrees that the Equipment will be used solely for commercial
manufacture and assembly of printed circuit cards and related activities.
Hibbing and AB agree that regardless of the manner of affixation, the Equipment
shall remain personal property and not become part of the real estate. Hibbing
and AB agree to keep the Equipment at 1300 Quince Orchard Blvd., Gaithersburg,
MD 20878-4106. Hibbing shall have no right to, and shall not, remove any of the
Equipment from such location, except as Hibbing and AB may hereafter mutually
agree in writing.

          15.3 Repairs. AB shall not be obligated to install, erect, test,
adjust, service or make any repairs or replacements. Hibbing shall effect and
bear the expense of all necessary repairs, maintenance, operation and
replacements required to be made to maintain the Equipment in good condition,
normal wear and tear excepted.

          15.4 Operation. Hibbing shall cause the Equipment to be operated by
trained employees only, and shall pay all expenses of operation.

          15.5 Indemnity. Hibbing shall indemnify and save AB harmless from any
and all injury to or loss of the Equipment from whatever cause, and from
liability or expenses (including attorneys' fees) arising out of the use or
maintenance thereof, but shall be credited with any amounts received by AB from
insurance procured by Hibbing. Damage for any loss or injury shall be based on
the then net book value of the Equipment, except as otherwise denoted on
Schedule 15.

          15.6 Purchase Option. At the expiration of the original term hereof or
at earlier termination if such termination was as a result of mutual agreement
or a right by Hibbing to terminate pursuant to subsection 9.2(a), if Hibbing is
not then in default hereunder, Hibbing shall have the option to purchase all but
not less than all the items of Equipment (other than items of Equipment which
are then still subject to the Leases described in Section 15.14) upon giving
written notice to AB not less than thirty (30) calendar days prior to the
expiration of the original term hereof (or shorter period, but as soon as
reasonably practical, in the case of such early termination). The purchase price
shall be One Dollar ($1.00). Upon Hibbing's exercise of the option, AB will
deliver title to such of the Equipment free and clear of all encumbrances.

          15.7 Insurance.

                  (a) All risk of loss, damage to or destruction of the
Equipment shall at all times be on Hibbing. Hibbing will procure forthwith and
maintain at Hibbing's expense insurance against all risks of loss or physical
damage to the Equipment for the lesser of the net book value or the full
insurable value thereof for the life of this Agreement and such other insurance
thereon in commercially reasonable amounts and against commercially reasonable
risks as AB may specify, and shall promptly deliver each policy to AB with an
endorsement attached thereto showing loss payable to AB and providing AB with
not less than thirty (30) calendar days written notice of cancellation. Each
such policy shall be in commercially reasonable form, terms and amount and with
insurance carriers reasonably satisfactory to AB. As to AB's interest in such
policy, no act or omission of Hibbing or any of its officers, agents, employees
or representatives shall affect the obligations of the insurer to pay the full
amount of any loss.

                  (b) Should Hibbing fail to furnish such insurance policy to
AB, or to maintain such policy in full force, or to pay any premium in whole or
in part relating thereto, then AB, without waiving or releasing any default or
obligation by Hibbing, may (but shall be under no obligation to) obtain and
maintain insurance and pay the premium therefor on behalf of Hibbing and charge
the premium to Hibbing under this Agreement. The full amount of any such premium
paid by AB shall be payable by Hibbing within thirty (30) calendar days of
notice thereof, and failure to pay same shall constitute an event of default
under this Agreement.

                  (c) In the event that monies become payable under any such
policy of insurance with respect to an item of Equipment, then Hibbing will, at
its option, either (i) pay over to AB such monies up to the then net depreciated
book value thereof on AB's books of account of such item or (ii) repair or
replace such item.

          15.8 Taxes. Hibbing shall comply in all material respects with all
laws, ordinances and regulations relating to Hibbing's possession, use or
maintenance of the Equipment, and save AB harmless against actual or asserted
violations, and pay all costs and expenses of every character occasioned by or
arising out of such use. Hibbing agrees that, during the term of this Agreement,
in addition to all other amounts provided herein to be paid, it will promptly
pay all taxes, assessments and other governmental charges (including penalties
and interest, if any, and fees for titling or registration, if required) levied
or assessed upon the interest of Hibbing in the Equipment or upon Hibbing's use
or operation thereof or on Hibbing's earnings arising therefrom.

          15.9 Title. All Equipment shall remain personal property, and title
thereto (or, in the case of the Equipment subject to the Leases described in
Schedule 15.14, a valid leasehold interest therein) shall remain in AB
exclusively. Hibbing shall keep the Equipment free from any and all liens and
claims, and shall not do or permit any actor thing to be done whereby AB's title
or rights may be encumbered or impaired. Hibbing will not change or remove any
insignia or lettering on the Equipment, which shall conspicuously identify each
item of the Equipment by suitable lettering thereon to indicate AB's ownership.
Hibbing shall give AB immediate notice of any attachment or other judicial
process affecting the Equipment, and indemnify and save AB harmless from any
loss or damage caused thereby.

          15.10 No Warranty. Hibbing acknowledges that is has inspected and is
fully familiar with the Equipment and agrees that it has bargained for a right
to use the Equipment without warranty by AB. Hibbing acknowledges that AB is not
the manufacturer or supplier of, nor a dealer in, the Equipment. AB represents
that the Equipment is in good working order and that no material maintenance has
been neglected. EXCEPT FOR THE FOREGOING, AND EXCEPT FOR THE WARRANTY OF TITLE
UNDER SECTION 15.9 AND THE WARRANTY OF TITLE TO BE GIVEN UPON EXERCISE OF THE
PURCHASE OPTION UNDER SECTION 15.6, AB MAKES NO

                                       14
<PAGE>   15
WARRANTY OR REPRESENTATION, EITHER EXPRESSED OR IMPLIED, AS TO THE FITNESS,
QUALITY, DESIGN, CONDITION, CAPACITY, SUITABILITY, MERCHANTABILITY OR
PERFORMANCE OF THE EQUIPMENT OR OF THE MATERIAL OR WORKMANSHIP THEREOF, IT BEING
AGREED THAT THE EQUIPMENT IS PROVIDED "AS IS", "WHERE IS" AND "WITH ALL FAULTS"
AND THAT ALL SUCH RISKS, AS BETWEEN AB AND HIBBING, ARE TO BE BORNE BY HIBBING
AT ITS SOLE RISK AND EXPENSE. Hibbing accordingly agrees not to assert any claim
whatsoever against AB based thereon. Hibbing further agrees, regardless of
cause, not to assert any claim whatsoever against AB for loss of anticipatory
profits, consequential, special, incidental or punitive damages. No oral
agreement, guaranty, promise, condition, representation or warranty shall be
binding,; all prior conversations, agreements or representations related hereto
and/or to said Equipment are integrated herein. AB, however, will give Hibbing
the benefit of all warranties, if any, made by manufacturers or suppliers of the
Equipment to AB. Claim by Hibbing against any manufacturer or supplier of
Equipment shall not effect Hibbing's obligations under this Agreement.

          15.11 Possession. AB covenants to and with Hibbing that AB is the
lawful owner (or, with respect to the Equipment subject to the Leases described
in Schedule 15.14, is the valid lessee) of said Equipment and that such
Equipment is and during the term of this Agreement will be free from all
encumbrances other than security interests held by or hereafter granted to its
lending institutions and that, subject thereto and to Hibbing's performing the
conditions hereof, Hibbing shall, subject to Section 15.1 hereof, peaceably and
quietly use the Equipment during said term without hindrance.

          15.12 Performance of Obligations of Hibbing by AB. In the event that
Hibbing shall fail duly and promptly to perform any of its obligations under the
provisions of this Article 15, AB may, at its option, perform the same for the
account of Hibbing without thereby waiving such default, and any amount paid or
expense (including reasonable attorneys' fees), penalty or other liability
incurred by AB in such performance, shall be payable by Hibbing upon demand.

          15.13 Further Assurances. Hibbing shall execute and deliver to AB,
upon AB's reasonable request and at AB's expense, such instruments and
assurances as AB deems necessary or advisable for the confirmation or perfection
of this Agreement and AB's rights hereunder, including, without limitation,
U.C.C. financing statements.

          15.14 Certain Equipment Leases.

                  (a) AB is the lessee under the equipment leases described in
Schedule 15.14 attached hereto and made part hereof (collectively the "Leases").
AB hereby grants to Hibbing the right to use the equipment leased under the
Leases during the Term hereof and Hibbing shall pay to AB all current
installments of regularly scheduled amounts required to be paid by AB
thereunder, when and as due. AB represents and warrants to Hibbing that, to
date, AB has performed and paid all obligations of AB under the Leases and no
event of default has occurred and is continuing under any of the Leases. During
the term of this Agreement: (i) AB will not terminate, modify or amend the
Leases without Hibbing's prior written consent (which may not be unreasonably
withheld or delayed); and (ii) AB will pay and perform all of its obligations
under the Leases. AB has provided Hibbing with true, correct and complete copies
of the Leases.

                  (b) Hibbing shall indemnify and hold AB harmless from any
liability or expense, including attorneys' fees, arising out of claims made,
suits or proceedings brought against AB by any party relating to Hibbing's use
or possession of the Equipment covered by the Leases other than on account of
the failure to obtain consents contemplated by this Section 15.14.

                                       15
<PAGE>   16
                  (c) AB will (at its expense) use its best good faith efforts
to promptly obtain the consents of the lessors and any third-parties necessary
to permit the consummation of the transactions contemplated by this Article 15
(including, without limitation, the assignments contemplated by subsection
15.14(d) below). If AB is unable to obtain such consent with respect to one or
more items of said Equipment and if, as a result thereof, Hibbing's use of said
Equipment during the term of this Agreement is prevented by a proceeding or
action taken by such lessor or third party, then the provisions of this Article
15 will terminate with respect to such item or items of Equipment, and AB will
hold Hibbing harmless from any and all claims and damages (including attorneys'
fees) arising out of the failure to obtain such consents. The provisions of
Article 12 will apply to this indemnity. Without limiting the foregoing, if the
parties have complied with their respective obligations to pay and perform the
Leases, and yet a lessor or third party prevents AB or Hibbing from exercising a
purchase option contained in a Lease (a "Non-Exercisable Lease") because of the
failure to obtain a required consent, then AB agrees to promptly pay or
reimburse Hibbing for commercially reasonable amounts payable or paid by Hibbing
to acquire such Equipment that are in excess of the amounts contemplated by the
terms of the Non-Exercisable Leases.

                  (d) At the termination or expiration of this Agreement,
provided Hibbing is not in default hereunder, AB will assign all of its right,
title and interest in and to the Leases and the Equipment in consideration for
Hibbing's agreement to pay and perform the lessee's prospective obligations
under the Leases.

          15.15 Computer.

                  (a) AB agrees that, for a period of nine (9) months from the
date hereof, it shall permit Hibbing to use the Hewlett-Packard computer
hardware and Growth Power software currently used by AB with the Equipment, but
no other hardware or software possessed by AB. AB agrees to maintain such
hardware and software in good working order during such nine (9) month period,
reasonable downtime for system maintenance and upgrades excepted. AB represents
that it is and will be during such nine (9) month period the lawful owner of
said hardware and licensee of said software, free of all encumbrances and with
authority to license the same to Hibbing hereunder.

                  (b) Hibbing may, at Hibbing's own expense, increase the disk
capacity of the computer hardware by 2Gb, but shall not make any other changes
to the hardware without the prior written consent of AB. Hibbing may not load
and run additional software on the hardware without AB's prior written consent.
If such consent is given, then, notwithstanding such consent, Hibbing shall be
responsible for any damage to AB's hardware or software. All provisions of this
Agreement relating to the care and maintenance of the Equipment shall apply
equally to AB's computer hardware and software. AB agrees that it will take
commercially reasonable steps to make at least daily archival backups of its
software and Hibbing's data) and that it will take commercially reasonable steps
to protect such backups from harm or damage. AB will make the backups available
at the end of normal business hours each day and Hibbing will be responsible for
the physical possession of backups after normal business hours.

                  (c) All of such computer hardware and software as well as all
of AB's data stored in such computers shall remain the sole property of AB.
Hibbing's data shall remain the sole property of Hibbing, and will be returned
promptly to Hibbing upon termination or expiration of this Section 15.15.

                  (d) The parties shall mutually agree on a schedule whereby
Hibbing shall cease to use AB's computer hardware and software in favor of
hardware and software to be acquired by Hibbing at its own expense. AB shall
provide reasonable assistance to Hibbing in connection with migration from AB's
system to Hibbing's. Nothing in this subsection (d) shall be deemed to extend
the twelve (12)-

                                       16

month term of this Section 15.15. At the expiration of such term, AB may remove
all of its computer hardware and Hibbing shall reasonably cooperate with and
assist AB in the removal.

                  (e) Any Confidential Information obtained by Hibbing pursuant
to the operation of this Section 15.15 shall be subject to the provisions of
Article 13 hereof.

negotiations with the landlord) then payable by AB pursuant to the Lease (as

this Article 16, AB or its representative may re-enter the Premises by force,
summary proceedings or otherwise, and remove all persons therefrom, without
being liable to prosecution therefor; provided, however, that AB will use its
best good faith efforts to provide Hibbing with at least thirty (30) calendar
day's prior notice (other than with respect to the end of the original term
hereof) Hibbing shall pay, at the same time as the fees becomes payable under
the terms hereof, a sum equivalent to the fees under Section 16.2 and additional
fees under Section 16.3.

                  (b) In the event that the relation of AB and Hibbing may cease
or terminate by reason of the re-entry of AB under the terms and covenants
contained in this Agreement or by the rejectment of Hibbing by summary
proceedings or otherwise, it is hereby agreed that Hibbing shall remain liable
and shall pay in monthly payments the fees under Section 16.2 which accrue
subsequent to the re-entry by AB and Hibbing expressly agrees to pay as damages
for the breach of the covenants herein contained, the difference between the
fees under Section 16.2 and additional fees under Section 16.3 and the rent
collected and received, if any, by AB during the remainder of the unexpired
term, such difference or deficiency between the fees and additional fees herein
reserved and the fees and additional fees collected, if any, shall become due
and payable in monthly payments during the remainder of the unexpired term, as
the amounts of such difference or deficiency shall from time to time be
ascertained. Hibbing waives all rights to redeem under any law of the State of
Maryland.

          16.13 Building Lease.

                  (a) This Article 16 is subject to the Lease dated March 31,
1989 between Penril Corp., as Tenant, and Real Estate Income Partners III,
Limited Partnership, as Landlord (the "Landlord"), and to the Sublease dated as
of November ___, 1996 between Penril DataComm Networks, Inc., as Sublessor (the
"Sublessor") and AB as Sublessee, copies of which have been delivered to AB
(collectively, the "Building Lease"). Hibbing agrees that it will use its best
efforts to cause its employees, agents, contractors and invitees not to violate
the Building Lease.

                  (b) Upon termination of the Building Lease for any reason,
this Article 16 shall thereupon automatically terminate. In such event neither
party shall have any further obligation or liability to the other pursuant to
this Article 16, except that if the Building Lease is terminated directly or
indirectly as a result of an act or omission of Hibbing or AB, the other party
will be entitled to whatever rights and remedies it may under this Agreement by
law or equity, and except Hibbing shall pay, at the same time as the fees
payable under the terms hereof, a sum equivalent to the fees under Section 16.2
and the additional fees under Section 16.3 for all periods (pro rated for
partial periods) during which Hibbing remains in possession of the Premises. AB
will use its best good faith efforts to provide Hibbing with sixty (60) calendar
days' prior notice of the termination or expiration of the Building Lease.

                  (c) The Building Lease describes the Landlord's and
Sublessor's duties. AB is not obligated to perform the Landlord's or Sublessor's
duties. If the Landlord or Sublessor fails to perform, Hibbing shall send AB a
notice. Upon receipt of the notice, AB shall then promptly notify the Landlord
and the Sublessor and demand that the Building Lease agreements be carried out.

                  (d) If AB terminates the Building Lease or if the Landlord's
or Sublessor's consent to this Article 16 is required but is not obtained and,
in either such case as a result thereof, Hibbing's use of the Premises during
the first twelve (12) calendar months of the term of this Agreement is prevented
by a proceeding or action taken by the Landlord or Sublessor, then: (i) AB will
hold Hibbing harmless from any and all claims and damages (including attorneys'
fees) arising out of or in connection with such proceeding or action and for
costs and expenses incurred by Hibbing to relocate its operations from the
Premises under expedited circumstances earlier than at the scheduled expiration
of this Agreement (the provisions of Article 12 will apply to this indemnity);
and (ii) at Hibbing's option, Hibbing may upon written notice to AB either (A)
terminate this Agreement with immediate effect (but otherwise in accordance with
the provisions of Article 9) or (B) adjust Hibbing's price model under
subsection 8.1(a) to include an eleven and 36/100 percent (11.36%) profit margin
applicable to purchase orders received on and after such notice.

                  (e) The provisions of the Building Lease are part of this
Agreement. During the term of this Agreement: (i) AB may, without the consent of
Hibbing, modify or amend the Building Lease in any manner that does not
adversely affect Hibbing; and (ii) AB agrees to pay and perform all of its
obligations under the Building Lease. AB represents and warrants to Hibbing
that, to date, AB has performed and paid all obligations of AB under the
Building Lease and has not received a notice, and has no knowledge, that an
event of default has occurred and is continuing under the Building Lease. AB has
provided Hibbing a true, correct and complete copy of the Building Lease.

                  (f) Hibbing shall have no authority to contact or make any
agreement with the Landlord or the Sublessor about the Premises or the Building
Lease. Hibbing shall not pay fees, additional fees or other charges to the
Landlord or the Sublessor, but only to AB.

          16.14 Early Termination. Any provision of this Agreement to the
contrary notwithstanding, AB may terminate this Article 16 upon one hundred
twenty (120) calendar days prior written notice to Hibbing. In such event,
Hibbing shall vacate the Premises within such one hundred twenty (120)
calendar-day period and this Article 16 shall terminate on the date Hibbing
vacates, but the remainder of this Agreement shall remain in full force and
effect.

          16.15 Eminent Domain. If the whole or a material part of the Premises
shall be acquired or condemned by eminent domain for any public or quasi-public
use or purpose, then and in that event, AB shall notify Hibbing thereof,
whereupon the term of this Article 16 shall cease and terminate from the date of
title vesting in such proceeding, and Hibbing shall have no claim for the value
of any unexpired term of this Article 16. In such event, the remainder of this
Agreement shall remain in full force and effect.

          16.16 Abatement of Fees. No diminution, abatement reduction or set off
of fees or additional fees shall be claimed or allowed except in the event the
Premises become untenantable without the fault of Hibbing.

          16.17 Subordination. Hibbing agrees that this Agreement shall be
subordinate to the Lease and to any mortgages, ground lease or other instruments
which may now or hereafter affect the Premises or any part thereof. Although no
additional instrument or act on the part of Hibbing shall be necessary to effect
such subordination, Hibbing shall execute and deliver such instruments of
subordination of this Agreement as may reasonably be requested by the Landlord
or Sublessor or by holders of said mortgages, leases or other instruments.

          16.18 Hibbing's Breach. If Hibbing breaches any covenant or condition
of this Article 16, AB may, on thirty (30) calendar days' notice to Hibbing (and
after Hibbing's failure to cure said breach within such notice period), cure
such breach at the expense of Hibbing and the reasonable amount of all expenses,
including reasonable attorney's fees, incurred by AB in so doing, shall be
deemed additional fees payable on demand.

          16.19 Mechanic's Liens. Each of AB and Hibbing shall, within thirty
(30) calendar days after notice from the other, remove or satisfy any mechanic's
lien for materials or labor claimed to have been furnished to the Premises on
behalf of the notified party, unless being contested in good faith.

          16.20 Possession. AB covenants to and with Hibbing that AB is the
lawful lessee under said Lease and that, subject to Hibbing's performing the
conditions hereof, Hibbing shall peaceably and quietly enjoy the Premises during
said term without hindrance.

                                  FORCE MAJEURE

         If any performance by either party shall be prevented, hindered or
delayed by reason of any cause beyond the reasonable control of such party
including, without limitation, acts of God, riots, fires, floods, unusually
severe weather, curtailment or termination of sources or supplies of energy or
power, inability to obtain or delay in obtaining materials or supplies, strikes
or other disputes involving such party or its subcontractors or suppliers, or
any other cause beyond the reasonable control of such party, whether similar or
dissimilar to those expressed hereinabove, such party shall be excused from
performance to the extent that its performance shall extend so long as the event
continues to prevent, hinder or delay the performance by such party. The party
whose performance is affected shall give the other party notice

                                       21
<PAGE>   22
within fifteen (15) calendar days of the occurrence specifying the occurrence,
the performance affected and the anticipated date, if any, on which performance
can be made. However, should performance be prevented for more than ninety (90)
consecutive calendar days, either party shall be entitled at its sole option to
terminate this agreement on fifteen (15) calendar days' prior written notice to
the other party. The provisions of Sections 9.3 and 9.4 will apply to any such
termination.

                                  MISCELLANEOUS

          18.1 Notices. Any notice required to be given under this Agreement
shall in writing and shall be deemed to have been duly given if delivered by
hand or mailed, certified or registered mail with postage prepaid or delivered
by express delivery or facsimile transmission to the respective parties at their
address set forth hereinabove or at such other address as may be hereafter
designated in writing to the other party.

          18.2 Severability. If in any jurisdiction, any provision of this
Agreement or its application to any party or circumstance is restricted,
prohibited or unenforceable, such provision shall, as to such jurisdiction, be
ineffective only to the extent of such restriction, prohibition or
unenforceability without invalidating the remaining provisions hereof and
without affecting the validity or enforceability of such provision in any other
jurisdiction or its application to other parties or circumstances. In addition,
if any one or more of the provisions contained in this Agreement shall for any
reason in any jurisdiction be held to be excessively broad as to time, duration,
geographical scope, activity or subject, it shall be construed by limited and
reducing it, so as to be enforceable to the extent compatible with the
application law of such jurisdiction as it shall then appear.

          18.3 No Waiver. The failure or omission of either party to insist, in
any instance, upon strict performance by the other party of any term or
condition of this Agreement or to exercise any of its rights hereunder shall not
be deemed to be a modification of any term hereof or a waiver or relinquishment
of the future performance of any such term or condition by such party, nor shall
such failure or omissions constitute a waiver of the right of such party to
insist upon future performance by the other party of any such term or condition.

          18.4 Assignability. This Agreement shall be binding upon and shall
inure to the benefit of the respective successors and assigns of the parties
hereto, provided, however, that neither AB nor Hibbing shall assign, transfer,
pledge or mortgage this Agreement to any person or party whatsoever (although
Hibbing may assign this Agreement in whole or in part to an Affiliate without
consent (but Hibbing may not be released from its obligations hereunder as a
result of such assignment without the consent of AB)).

          18.5 Entire Agreement. This Agreement constitutes the entire agreement
of the parties with respect to the subject matter hereof, and all other prior or
contemporaneous agreements of the parties with respect to said subject matter
are hereby merged into and superseded by this Agreement. This Agreement may not
be changed, modified or amended other than by a further written agreement signed
by both parties hereto.

          18.6 Governing Law; Etc. This Agreement shall be governed by, and
shall be construed and interpreted in accordance with, the law of the State of
Maryland, including without limitation the Maryland Uniform Commercial Code.

          18.7 Mutual Agreement. This Agreement embodies the arms-length
negotiation and mutual agreement between the parties hereto and shall not be
construed against either party as having been drafted by it.

          18.8 Headings and Counterparts. Headings are inserted for reference
purposes only and shall not affect the interpretation or meaning of this
Agreement. This Agreement may be executed in several counterparts, each of which
shall be deemed to be an original but all of which, together, will constitute
one and the same instrument.

          18.9 Disclaimer of Association. This Agreement shall not be construed
as creating a partnership, joint venture, agency or any other association which
would impose upon one party liability for the acts or omissions of the other.

          18.10 Commissions and Finders' Fees. Each of the parties represents
that the negotiations relative to this Agreement and the transactions
contemplated hereby have been carried on directly by AB with Hibbing and in such
manner as not to give rise to any claims against any of the parties hereto for a
brokerage commission, finders' fee or other like payment. Insofar as any such
claims are made which are alleged to be based on an agreement or arrangements
made by, or on behalf of, a party, such party agrees to indemnify and hold the
other parties harmless from and against all liability, loss, cost, charge or
expense, including reasonable counsel fees, arising therefrom.

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

party), execute and deliver such other documents and instruments and take such
other actions as the other party may reasonably request in order to more
effectively consummate the transactions contemplated hereby.

                                   ARTICLE IV

                      RELATED AGREEMENTS AND TRANSACTIONS

         4.01    Hold Harmless

                 (a)      Subject to the provision of Article VII hereof,
Seller and Penril, jointly and severally, covenant and agree to hold Purchaser
and its Affiliates harmless from any liability and out-of-pocket expenses,
including attorneys' fees and disbursements, arising out of successful claims
made, or suits or proceedings brought, against Purchaser or its Affiliates by
any party relating to the Retained Liabilities.

                 (b)      Subject to the provision of Article VII hereof,
Purchaser covenants and agrees to hold Seller, Penril and their Affiliates
harmless from any liability and out-of-pocket expenses, including attorneys'
fees and disbursements, arising out of successful claims made, or suits or
proceedings brought, against Seller, Penril or their Affiliates by any party
relating to the Assumed Liabilities or Purchaser's acts or omissions arising or
accruing after the Closing.

         4.02    Bulk Sales Laws.  Subject to the provisions of Article VII
hereof, Seller and Penril, jointly and severally, covenant and agree to
indemnify Purchaser from any and all successful claims made by creditors of
Seller (other than creditors with respect to the Assumed Liabilities) relating
to provisions of the "bulk sales laws" of the State of New York which may be
applicable to the transactions contemplated hereby and from all reasonable
out-of-pocket costs (including reasonable attorneys' fees) incurred in the
defense of any such claims made under such laws.

         4.03    Mail Received After Closing.  Following the Closing, Purchaser
may receive and open all mail addressed to Seller and deal with the contents
thereof in its discretion to the extent that such mail and the contents thereof
relate to the Acquired Assets or the Assumed Liabilities.  Purchaser agrees to
deliver or cause to be delivered to Seller all other mail received addressed to
Seller which does not relate to the Acquired Assets or the Assumed Liabilities;
and Seller agrees to deliver or cause to be delivered to Purchaser all mail
received by Seller or Penril relating to the Acquired Assets or the Assumed
Liabilities.

         4.04    Seller's Records; Access by Seller.  After the Closing,
Purchaser shall afford Seller, Penril, their counsel, accountants and other
representatives access to and assistance with such





                                       5
<PAGE>   11
books and records acquired by Purchaser pursuant hereto as may be reasonably
necessary in order for Seller and Penril to prepare tax reports and returns
required to be filed by it, to respond to inquiries by governmental
authorities, to deal with Retained Liabilities or for other appropriate
reasons.  Purchaser shall not dispose of any such books or records of Seller
until it has given reasonable notice to Penril of its intention to do so and
given Penril a reasonable opportunity to take possession of such books and
records to be disposed of.

         4.05    Employee Matters.

                 (a)      Effective as of the Closing, Purchaser shall offer
employment to all persons employed by Seller listed on Schedule 4.05 hereto
(the "Covered Employees") at substantially the same wages, salary, benefits,
hours and conditions of employment as in effect immediately prior to the
Closing.
                 (b)      Purchaser shall be responsible for and cause to be
paid in the normal course of business the vacation and holiday pay for Covered
Employees reflected on Schedule 4.05 hereof.

                 (c)      Purchaser shall be responsible and liable for any
payment in the nature of severance pay due to any Covered Employee by reason of
any action taken by Purchaser after the Closing.

                 (d)      Seller shall be responsible for payment of all claims
made by Covered Employees and their covered dependents under Seller's group
health and dental benefit plans prior to the Closing Date.  Purchaser shall
provide group health and dental benefit plans for the Covered Employers and
their covered dependents from and after the Closing Date.  Purchaser's group
health and dental plans shall take into account in the plan year in which the
Closing occurs any expenses incurred by such Employees and their covered
dependents during such plan year but prior to the change-over to Purchaser's
plans for the purpose of satisfying deductible or coinsurance requirements to
the same extent as if such expenses had been incurred after such change-over.

                 (e)      As soon as is practicable after the Closing Date,
Purchaser shall establish a defined contribution savings plan intended to
qualify under Section 401(k) of the Internal Revenue Code of 1986, as amended
(the "Code"), in which the Covered Employees shall be eligible to participate
as of the Closing Date (the "Purchaser's Successor Plan").  Purchaser shall, as
soon as practicable after the Closing Date provide Seller with a copy of
Purchaser's Successor Plan.  Within 60 days following Seller's receipt thereof,
Seller shall cause the trustee of Seller's 401(k) plan in which the Covered
Employees participate prior to the Closing to transfer assets equal to the
account values of all such Covered Employees on a fully vested basis to the
trustee of Purchaser's Successor Plan.  Purchaser's Successor Plan shall
recognize service with Seller and participation in Seller's plan for purposes
of determining vesting, eligibility to receive benefits and other
service-related rights in Purchaser's Successor Plan, and in no event shall any
Employee's vested interest in his





                                       6
<PAGE>   12
account (including in respect of future accruals or allocations) under
Purchaser's Successor Plan be less than his vested interest in his account in
Seller's plan.

                 (f)      Purchaser shall be responsible and liable for any
claim in respect of the Covered Employee arising under any state worker's
compensation or similar law which is based on any occurrence on or after the
Closing Date.

                 (g)      Purchaser agrees that for a period of 60 days
following the Closing Date, Purchaser shall not undertake a "plant closing" or
a "mass layoff" (as such terms are defined in the Worker Adjustment and
Retraining Notification Act ["WARN"]) or undertake any other actions requiring
notification pursuant to any similar state or local law or regulation to any
person or entity.  Purchaser further agrees and acknowledges that on and after
the Closing Date, Purchaser shall be solely responsible for compliance with any
federal, state, or local laws and regulations relating to plant closing or a
substantial layoff of personnel.

                 (h)      Notwithstanding anything to the contrary contained
herein, Purchaser agrees that it shall, effective as of the Closing Date, put
in place medical and health care benefit programs covering the Covered
Employees so that no such Covered Employee will suffer a break in coverage
under such types of programs and so that Seller shall have no responsibility or
liability in respect of such Covered Employees under the "continuation
coverage" provisions of the Consolidated Omnibus Budget Reconciliation Act of
1985, as amended ("COBRA"), or Part 6 of Title I of ERISA or Section 4980B of
the Code.

         4.06    Allocation Agreement.  At the Closing, Purchaser and Seller
are entering into an allocation agreement satisfying the requirements of
Section 1060 of the Code and the regulations promulgated pursuant thereto.
Neither Purchaser nor Seller shall take a reporting position contrary to the
allocation agreement.

         4.07    Covenant of Non-competition; No Poaching of Employees.

                 (a)      Seller and Penril hereby acknowledge the competitive
nature of Seller's business and, in consideration of the purchase by Purchaser
of the Acquired Assets, Seller and Penril therefore, jointly and severally,
agree that for a period of three (3) years after the Closing Date, neither
Seller, Penril or any Affiliate thereof shall, for itself, or as an agent of,
or on behalf of, or in conjunction with, any person, firm or corporation, or as
a partner of any partnership, or as a shareholder of any corporation (excluding
the ownership of fewer than 5% of the outstanding voting shares of any publicly
traded corporation), own, manage, acquire, operate, control or participate in
the ownership, management, operation or control of, any business which competes
with Seller's business, as constituted immediately prior to the Closing.





                                       7
<PAGE>   13
                 (b)      Purchaser agrees that for a period of three (3) years
after the Closing neither Purchaser nor any Affiliate thereof shall solicit for
employment, offer employment to, or employ any employee of Seller or Penril
other than the Covered Employees.  Seller and Penril jointly and severally
agree that for a period of three (3) years after the Closing neither Seller,
Penril nor any Affiliate thereof shall solicit for employment, offer employment
to or employ any employee of Purchaser.

                 (c)      In addition to any other remedy or relief available
for any breach or threatened breach of any of the provisions of this Section
4.07, the non-breaching party shall be entitled to seek injunctive relief for
any such breach, and the breaching party waives the making of a bond in
connection therewith.

         4.08    Change of Name.  Promptly following the Closing, Seller shall
amend its Certificate of Incorporation so as to change its name to a name not
including "Electro-Metrics" or any derivative thereof.  Thereafter neither
Seller nor any Affiliate thereof shall use the name "Electro-Metrics" or any
derivative thereof.  Purchaser shall have no right to, and shall not, use the
name "Penril" or any deviation thereof.

         4.09    Lease Termination or Assignment.  Seller currently leases real
property in Johnstown, New York pursuant to a sublease dated as of March 1,
1995 (the "Lease") between Crossroads Incubator Corp. and Seller.  At the
Closing, the parties will take all necessary action to either (a) terminate the
Lease, effective upon the Closing, without payment by Seller of any additional
consideration, or (b) cause the Lease to be assigned to and assumed by
Purchaser and Seller to be released from further liability with respect to the
Lease.

         4.10    Payment to Bach; Releases.  At the Closing, Penril shall pay
to Bach a bonus of $90,000.  Except for such payment and payment of Bach's
regular salary through the Closing Date, neither Seller nor Penril shall have
any further liability or obligation to Bach.  Bach shall upon the Closing
execute and deliver a release to Penril and Seller in the form of Exhibit C
hereto, and Penril and Seller shall upon the Closing execute and deliver to
Bach a release in the form of Exhibit D hereto.

         4.11    Agreement Non-exclusive.  (a) Purchaser expressly agrees that
notwithstanding this Agreement or any provision hereof, Seller and Penril shall
have the right until the Closing to solicit or entertain offers from, enter
into negotiations with and furnish information to other parties with respect to
a merger, sale of stock or assets or other business combination or disposition
transaction involving Seller (collectively "Transactions" or individually a
"Transaction"); provided that until the earlier of (i) the Closing or (ii)
December 18, 1996, Seller and Penril shall refrain from entering into
negotiations for any Transaction in which any person who on November 1, 1996
was an officer, director or employee of Penril or Access Beyond, Inc. would act
as a principal.





                                       8
<PAGE>   14
                 (b)      Bach shall conduct tours and discussions concerning
business of Seller for prospective third party purchasers of Seller and shall
disclose to such third parties the same forecasts and projections which
Purchaser discloses or has disclosed to parties from which it is seeking
financing.

                 (c)      If Penril and Seller determine to pursue a
Transaction with another party, Penril and Seller may terminate this Agreement
upon written notice to Purchaser, whereupon this Agreement shall immediately
terminate and no party shall have any further obligation or liability with
respect thereto.

be subject to the following limitations and adjustments: (i) the provisions of
Section 7.02 shall be effective only when the aggregate amount of all Damages

$35,000, in which case Seller and Penril shall be liable for only such amounts
as exceed $35,000; (ii) the amount of any claim by any party for

investigation, suit, proceeding or demand, (i) no compromise or settlement

Purchaser, and Purchaser hereby covenants and agrees with Seller and Penril
that:

         9.01    Full Access.  Seller shall afford to Purchaser, its counsel,

order that Purchaser may have full opportunity to make such investigations as
it shall desire to make of the affairs of Seller.

         9.02    Confidentiality.  Each party will hold and will cause its
consultants and advisors to hold in strict confidence, unless compelled to
disclose by judicial or administrative process or, in the opinion of its
counsel, by other requirements of law, all documents and information concerning

fault of such party) and each party will not release or disclose such
information to any other person, except its auditors, attorneys, financial
advisors, bankers and other consultants and advisors in connection with this

hold in confidence, and such information shall not be used to the detriment of
the other party, and all such documents (including copies thereof) shall
immediately thereafter be returned to the other party upon the written request
of such other party.

         9.03    No Public Announcement.  No party hereto shall make any
announcement concerning this Agreement or the transactions contemplated thereby
without the prior written approval of the other parties, which approval shall

that the negotiations relative to this Agreement and the transactions
contemplated hereby have been carried on by Seller and Penril directly with
Purchaser and in such manner as not to give rise to any claims against any of
the parties hereto for a brokerage commission, finders' fee or other like
payment.  Insofar as any such claims are made which are alleged to be based on
an agreement or arrangements made by, or on behalf of, a party, such party
agrees to indemnify and hold the other parties harmless from and against all
liability, loss, cost, charge or expense, including reasonable counsel fees,
arising therefrom.

agreement or condition herein may be expressly waived in writing by Purchaser

strict compliance with such obligation, covenant, agreement or condition shall
not operate as a waiver of, or estoppel with respect to, any subsequent or
other failure.

         13.04   Expenses.  Each of the parties hereto will pay its own
expenses incurred by it or on its behalf in connection with this Agreement or

Agreement are inserted for convenience only and shall not constitute a part
hereof.

         WHEREAS, the Asset Purchase Agreement, dated November 13, 1996 (the

         WHEREAS, all of the terms and conditions precedent provided in the
Agreement have been met and performed by the respective parties thereto, and
the parties now desire to carry out the intent and purpose of the Agreement by
Grantor's execution and delivery to Grantee of this instrument evidencing the
vesting in Grantee of all of the assets and rights hereinafter described, in
addition to such other instruments as Grantee shall have otherwise received or
may hereafter reasonably request.

         NOW, THEREFORE, in consideration of the premises and of other valuable
consideration to Grantor in hand paid by Grantee, at or before the execution
and delivery hereof, the receipt and sufficiency of which by Grantor is hereby
acknowledged, Grantor has conveyed, granted, bargained, sold, transferred, set
over, assigned, alien, remised, released, delivered and confirmed;  and by this
Indenture and Bill of Sale does convey, grant, bargain, sell, transfer, set

         Section 1.       Grantor hereby constitutes and appoints Grantee, its
successors and assigns, Grantor's true and lawful attorney and attorneys, with
full power of substitution, in Grantor's name and stead, but on behalf and for
the benefit of Grantee, its successors and assigns, to demand and receive any
and all of the Acquired Assets, and to give receipts and releases for and in
respect of the same, and any part thereof, and from time to time to institute
and prosecute in Grantor's name, or otherwise, for the benefit of Grantee, its
successors and assigns, any and all proceedings at law, in equity or otherwise,
which Grantee, its successors or assigns, may deem proper for the collection or
reduction to possession

<PAGE>   29
of any of the Acquired Assets or for the collection and enforcement of any
claim or right of any kind hereby sold, conveyed, transferred and assigned, or
intended so to be, and to do all acts and things in relation to the Acquired
Assets which Grantee, its successors or assigns shall deem desirable, Grantor
hereby declaring that the foregoing powers are coupled with an interest and are
and shall be irrevocable by Grantor or by Grantor's dissolution or in any
manner or for any reason whatsoever.

         Section 2.       Grantor further authorizes Grantee, its successors
and assigns, to receive and open all mail, telegrams and other communications,
and all express or other packages, addressed to Grantor or to any of their
officers and to retain the same insofar as they relate to the Acquired Assets,
but any such mail, telegrams, communications or express or other packages not
relating to the Acquired Assets shall be forwarded with reasonable dispatch to
the Grantor.  The foregoing shall constitute full authorization to the postal
authorities, all telegraph and express companies, and all other persons to make
delivery of such items to Grantee.

         Section 3.       Grantor hereby covenants that, from time to time
after the delivery of this instrument, at Grantee's request and without further

further acts, deeds, conveyances, transfers, assignments, powers of attorney
and assurances as reasonably may be required more effectively to convey,
transfer to and vest in Grantee, and to put Grantee in possession of, any of
the Acquired Assets.

         Section 4.       Notwithstanding any of the provisions of the
foregoing, this instrument shall not constitute an assignment to Grantee of any
claim (including but not limited to claims for refunds of taxes), contract,
license, lease, commitment, sales order or purchase order if an attempted
assignment of the same without the consent of the other party thereto would
constitute a breach thereof or in any way impair the rights of Grantor
thereunder; provided, however, that in the case of any of the foregoing,
Grantor shall endeavor to obtain such consents promptly and if any be
unobtainable, to use its best efforts to assure to Grantee the benefits
thereof.

         Section 5.       Nothing in this instrument, express or implied, is
intended or shall be construed to confer upon, or give to, any person, firm or
corporation other than Grantee and its successors and assigns, any remedy or
claim under or by reason of this instrument or any terms,

covenants or condition hereof, and all the terms, covenants or condition
hereof, and all the terms, covenants and conditions, promises and agreements in
this instrument contained shall be for the sole and exclusive benefit of
Grantee and its successors and assigns.

         Section 6.       This instrument is executed by, and shall be binding
upon, Grantor, its successors and assigns, for the uses and purposes above set

        Re: Asset Purchase Agreement

Gentlemen:

        Reference is made to the Asset Purchase Agreement dated November 13,
1996, as amended by letter agreements dated January 6, 1997, and February 26,
1997 (as so amended, the "Agreement"), among EMI Holding Corp.,
Electro-Metrics, Inc. and Penril DataComm Networks, Inc. Unless otherwise
indicated, capitalized terms used herein shall have the same meaning as in the
Agreement.

        Penril has assigned all of its rights, duties, liabilities and
obligations under the Agreement to Access Beyond, Inc. a Delaware Corp.
pursuant to Section 13.06 thereof. Thus Access Beyond has been substituted for
Penril in all purposes of the Agreement.

        The parties desire to further amend the Agreement as follows.

        1.      Amendments to the Agreement

        (A)     Section 2.02 of the Agreement is hereby deleted in its entirety
and the following new Section 2.02 substituted therefor:

                "2.02   Consideration. In consideration of the sale, assignment,
                transfer and delivery of the Acquired Assets, Purchaser shall:

                        (a)  pay to Seller in cash at the Closing, by certified
                or official bank check or wire transfer of funds to an account
                described by Seller, the sum of $2,000,000;

                        (b)  issue and deliver to Seller at the Closing a
                subordinated promissory note of Purchaser in the principal
                amount of $1,000,000 (the "2 Year Note"), in form and substance
                satisfactory to Seller which shall mature on the second
                anniversary of the Closing; require payments of principal and
                interest in quarterly installments of $50,000 each, commencing
                on the Closing


<PAGE>   41
                                      -2-


        Date; bear interest at a variable rate at all times equal to the rate
        charged to Purchaser by its bank lender; be subordinated to Purchaser's
        indebtedness to its bank lender, provided the principal balance of such
        debt shall at no time exceed $5,000,000; accelerate upon default or upon
        a sale or change of control or IPO of Purchaser; and require Purchaser
        to use its best efforts to obtain additional credit and to apply 100%
        of credit obtained under new facilities or guarantees and 75% of all
        increases in availability under its existing facilities to prepayment
        of the 2 Year Note;

                (e)     issue and deliver to Seller at the Closing a
        subordinated note of Purchaser in the principal amount of $500,000 (the
        "5 Year Note") in form and substance satisfactory to Seller which shall
        be payable in one installment of principal on the fifth anniversary of
        the Closing; bear interest at a variable rate at all times equal to 2%
        above the rate charged to Purchaser by its bank lender; be subordinated
        in the same manner as the 2 Year Note; accelerate upon default
        (including default the 2 Year Note) or upon a sale or change of control
        or IPO of Purchaser; and require monthly payments of accrued interest
        commencing on the first day of the month following that in which the 2
        Year Note is repaid in full;

                (d)     in repayment of cash advances from Access Beyond to
        Seller, issues and deliver to Seller at the Closing seven-year warrants
        (the "Warrant"), in form and substance satisfactory to Seller, for the
        purchase of the number of shares Purchaser's Preferred Stock, $.001 par
        value per share ("Preferred Stock"), such that Seller receives twelve
        percent (12%) of the total shares of stock outstanding after giving
        effect to the issuance of such shares on a fully diluted basis (for
        purposes of this calculation, Preferred Stock shall be assumed to be
        equivalent to Common Stock); provided that the number of shares shall be
        subject to adjustment as follows: (i) for each additional $50,000 cash
        advance made by Access Beyond to Seller from January 1, 1997 to the
        Closing Date, the number of shares Preferred Stock issuable to Seller
        hereunder shall be increased by that number of shares equal to one
        percent (1%) of all shares of Purchaser outstanding after giving effect
        to the issuance of such shares and (ii) for each $50,000 cash repaid by
        Seller to Access Beyond from January 1, 1997 to the Closing Date, the
        number of shares of Preferred Stock issuable hereunder shall be
        decreased by a like one percent (1%), provided that nothing in this
        Agreement shall require Access Beyond to make further advances to
        Seller. The Preferred Stock shall be non-voting shall pay dividends
        equal to any dividends paid on Purchaser's Common Stock and shall have a
        liquidation preference over Common Stock equal to the

                                      -3-


        amount that would be payable with respect to the Preferred Stock
        pursuant to the resale option provided to the holder pursuant to the
        Warrant Agreement (as hereinafter defined), and shall not be redeemable,
        except at the option of the holder as provided in the Warrant Agreement;
        and

                (e)     assume the Assumed Liabilities and deliver to Seller at
        the Closing an Instrument of Assumption in the form of Exhibit A
        hereto."

        (B)     Subsection 3.03(a) of this Agreement is hereby deleted in its
entirety and the following substituted therefor:

                "(a) the consideration set forth in subsection 2.02(a) and (d),
        the 2 Year Notes, the 5 Year Note and the Warrants."

        (C)     Section 4.13 of the Agreement is hereby deleted in its entirety
and the following substituted therefor;

        Purchaser shall execute and deliver an agreement (the "Warrant
        Agreement"), in form and substance satisfactory to Seller, providing,
        inter alia (a) an option for Seller to resell the Warrants or underlying
        shares of Preferred Stock to Purchaser for an aggregate price equal to
        the sum of $400,000, plus the amount of any additional advances made by
        Access Beyond to Seller from January 1, 1997 to the Closing Date (or
        minus any amount repaid to Access Beyond by Seller from January 1, 1997
        to the Closing Date) plus a return on that sum calculated at 2% above
        the rate of interest charged to Purchaser by its bank lender from time
        to time, compounded annually, with the option to be exercisable at any
        time after the fifth anniversary of the Closing but before the close of
        business on the seventh anniversary or earlier upon a sale or change of
        control or IPO of the Purchaser and (b) appropriate representations
        and warranties with respect to the Warrants and the underlying Preferred
        Stock."
