                                    SUMMARY
 
   
     The following is a summary of certain information contained elsewhere in
this Prospectus and is qualified by the more detailed information set forth
elsewhere in this Prospectus which should be read in its entirety. Unless the
context otherwise indicates, all references to the operations of the Company in
this Prospectus shall include the operations of the Remote Access Business (as
hereinafter defined) by Penril prior to the Distribution and assumes that the
actions set forth under "The Distribution" have taken place. Capitalized terms
used in this Summary but not defined in this Summary have the respective
meanings ascribed to them elsewhere in this Prospectus.
    
 
                              ACCESS BEYOND, INC.
 
   
     The Company is a wholly owned subsidiary of Penril, organized by Penril for
the sole purpose of effecting the Distribution and the Merger. The Company was
incorporated on July 23, 1996. The mailing address of the Company's principal
executive offices is currently 1300 Quince Orchard Boulevard, Gaithersburg,
Maryland 20878, and the phone number is (301) 921-8600.
    
 
                                  TRANSACTIONS
 
   
     Penril has entered into a Plan and Agreement of Merger dated as of June 16,
1996, as amended on August 5, 1996 (the "Merger Agreement") among Penril, Bay
and a subsidiary of Bay, pursuant to which, upon the terms and subject to the
conditions set forth therein, Penril will be merged with the subsidiary of Bay,
with Penril surviving as a wholly-owned subsidiary of Bay. Prior to consummation
of the Merger, the Board of Directors of Penril will declare a distribution in
the form of a dividend to holders of Penril Stock, as of the close of business
on the Record Date, on the basis of one share of Company Stock for each share of
Penril Stock held on the Record Date. The shares to be distributed will
constitute all of the issued and outstanding shares of Company Stock immediately
following the Distribution. Following the Distribution, the Company will be an
independent company and the Company Stock will be publicly traded on Nasdaq. See
"The Distribution" and "Description of Capital Stock." The Distribution is
intended to be tax-free to Penril stockholders for federal income tax purposes.
    
 
   
     Pursuant to the Merger Agreement, at the effective time of the Merger (the
"Effective Time"), each issued and outstanding share of Penril Stock (other than
shares of Penril Stock that are owned by Penril as treasury stock and other than
any shares of Penril Stock that are owned beneficially by Bay or any wholly
owned subsidiary of Bay, which will be automatically cancelled without
consideration) will be converted into the number of shares of common stock, par
value $.01 per share, of Bay (the "Bay Stock") equal to a specified ratio
determined by dividing $10 by the average closing price for Bay Stock for a
specified period prior to the Effective Time. Each of the options to purchase
Penril Stock outstanding at the Effective Time will be assumed by Bay and,
immediately after the Effective Time, will be deemed to constitute, without any
action on the part of the holder thereof, an option to acquire, as of the
Effective Time, Bay Stock on the same terms and conditions as were applicable
under such option at the Effective Time, subject to adjustment of the number of
shares and the exercise price for the conversion ratio referred to above. The
terms of the Merger are as described under "The Merger Agreement -- The Merger"
in the Proxy Statement/Prospectus of Penril and Bay (the "Proxy
Statement/Prospectus") to which this Prospectus is Annex II.
    
 
   
     Immediately prior to the Distribution, Penril will transfer (the
"Transfer") to the Company substantially all of its assets and liabilities other
than assets and liabilities related to Penril's modem business (the "Modem
Business"). In addition, the Company and Penril have agreed to indemnify each
other after the Distribution with respect to certain losses, damages, claims and
liabilities arising primarily from their respective businesses. See "Certain
Transactions -- Indemnification Agreement."
    
 
   
     The foregoing is a brief summary of certain terms of the Merger affecting
Penril. A more complete description of the Merger and the Merger Agreement may
be found in the Proxy Statement/Prospectus. The Distribution Agreement between
Penril and the Company is more fully described herein under "Certain
Transactions -- Distribution Agreement."

<TABLE>
<S>                                    <C>
Distributing Company.................. Penril DataComm Networks, Inc., a Delaware corporation
                                       ("Penril").
Distributed Company................... Access Beyond, Inc., a Delaware corporation (the "Com-
                                       pany"). The Company will engage in the development and
                                       marketing of network access devices which enable
                                       local, remote or mobile users to access network
                                       resources located at remote sites, central sites or
                                       any other point in the network (the "Remote Access
                                       Business"). In addition, Penril is currently in the
                                       process of selling two subsidiaries, Technipower, Inc.
                                       ("Technipower"), a manufacturer of uninterruptible
                                       power supplies and power regulating equipment, and
                                       Electro-Metrics, Inc. ("EMI"), a manufacturer of
                                       sophisticated high frequency instrumentation
                                       equipment. Although it is anticipated that Technipower
                                       will be sold prior to the Transfer, it is unlikely
                                       that EMI will be sold prior to the Transfer. In the
                                       event Technipower or EMI is not sold prior to the
                                       Transfer, the assets and liabilities of the unsold
                                       subsidiary will be transferred to the Company as part
                                       of the Transfer. See "Business -- Discontinued
                                       Operations."
Shares to be Distributed.............. 11,993,000 shares of Company Stock based on 11,993,000
                                       shares of Penril Stock expected to be outstanding on
                                       the Record Date. See "Description of Capital Stock."
                                       Such shares will constitute all of the issued and
                                       outstanding shares of Company Stock immediately
                                       following the Distribution.
Distribution Ratio.................... One share of Company Stock for each share of Penril
                                       Stock held on the Record Date. See "The
                                       Distribution -- Manner of Effecting the Distribution."
Risk Factors.......................... Stockholders should consider certain factors discussed
                                       under the heading "Risk Factors" beginning on page 9.
Relationship with Penril
  After the Distribution.............. As of the Distribution Date, the Company and Penril
                                       will enter into several agreements to define their
                                       ongoing relationships. These agreements relate to the
                                       provision of certain administrative services by the
                                       Company to Penril, the license of certain trademarks,
                                       trade names and service marks for use in the business
                                       of the Company, indemnification for various claims and
                                       development of certain technology. See "Certain
                                       Transactions."

Federal Income Tax Consequences....... The Board of Directors of Penril has received an
                                       opinion from its tax counsel to the effect that, on
                                       the basis of the facts, representations and
                                       assumptions set forth in the opinion, for federal
                                       income tax purposes, it is more likely than not that
                                       (i) the Distribution will qualify as a tax-free
                                       spin-off pursuant to Section 355 of the Internal
                                       Revenue Code of 1986, as amended (the "Code") and (ii)
                                       the Merger will qualify as a reorganization within the
                                       meaning of Section 368(a)(1)(B) of the Code. If the
                                       tax-free nature of the Merger in invalidated, it would
                                       reduce the likelihood that the Distribution will
                                       qualify as a tax-free spin-off pursuant to Section 355
                                       of the Code. No ruling from the Internal Revenue
                                       Service ("IRS") has been or will be sought with
                                       respect to any aspect of the Distribution. For a more
                                       detailed discussion of the federal income tax conse-
                                       quences of the Distribution to the Penril
                                       stockholders, see "Risk Factors -- Certain Tax
                                       Considerations" and "The Distribution -- Certain
                                       Federal Income Tax Consequences of the Distribution."
Post-Distribution Dividend Policies... The Company does not anticipate paying dividends for
                                       the foreseeable future.
Company Stock Listing................. The Company has applied to have the Company Stock
                                       listed for trading on Nasdaq under the symbol "ACCB."
Record Date........................... It is expected that the Record Date will be on or
                                       immediately after receipt of approval by the Penril
                                       stockholders of the Merger, the Transfer and the
                                       Distribution.
Distribution Agent, Transfer Agent
  and Registrar....................... Continental Stock Transfer & Trust Company
Distribution Date..................... It is expected that the Distribution Date will be on
                                       or about November 19, 1996. As soon as practicable
                                       thereafter, Penril will commence mailing certificates
                                       representing shares of Company Stock. Holders of
                                       Penril Stock will not be required to make any payment
                                       or take any action, including tendering stock
                                       certificates, in order to receive Company Stock. See
                                       "The Distribution -- Manner of Effecting the

                                  RISK FACTORS
 
     Holders of Penril Stock should be aware that the Distribution and ownership
of Company Stock involves certain risks, including those described below, which
could adversely affect the value of their holdings of Company Stock. Neither
Penril nor the Company makes, nor have they authorized any other person to make,
any representation about the future market value of Company Stock.
 
STAND ALONE COMPANY
 
   
     The Company was recently incorporated for the purpose of effecting the
Distribution and the Merger and, as a corporation, does not have any operating
history. However, the Remote Access Business, as conducted by Penril prior to
the Distribution, has an operating history consisting of the development and
sales of local area network ("LAN") and host access products (the "LAN and Host
Access products") and the development of a new product family called Access
Beyond. See "Business -- Products."
    
 
ABSENCE OF TRADING MARKET FOR COMPANY STOCK
 
     There is currently no established public trading market nor has there been
any established public trading market for Company Stock. The Company has applied
to have the Company Stock listed for trading on Nasdaq. There can be no
assurance as to the prices at which Company Stock will trade after the
Distribution Date. Until Company Stock is fully distributed and an orderly
trading market develops (if one does), the prices at which such stock trades may
fluctuate significantly. Prices for Company Stock will be determined in the
marketplace and may be influenced by many factors, including the operating
performance of the Company, the depth and liquidity of the market for Company
Stock, investor perception of the Company and general economic and market
conditions.
 
DEPENDENCE ON KEY MANAGEMENT
 
   
     If the Company is to be successful, its success will be due in large part
to the performance of Ronald A. Howard, the Company's President and Chief
Executive Officer, and, to a lesser extent, of other key management personnel.
The loss of Mr. Howard's services could adversely affect the Company's ability
to achieve profitability and growth. Although the Company anticipates it will
have an employment contract with Mr. Howard which will provide for his continued
employment, no assurance can be given that the Company will be able to retain
the services of Mr. Howard or any other key management personnel. See
"Management -- Executive Compensation" and "Management -- Employment and
Consulting Agreements."
    
 
TECHNOLOGICAL CHANGES
 
     The market for networking products is subject to rapid technological
change, evolving industry standards and frequent new product introductions, and
therefore requires a high level of expenditures for research and development.
The Company may be required to incur significant expenditures to develop new
integrated product offerings. There can be no assurance that customer demand for
products integrating network connectivity and remote access technologies will
grow at the rate expected by the Company, that the Company will be successful in
developing, manufacturing and marketing new products or product enhancements
that respond to these customer demands or to evolving industry standards and
technological change, that the Company will not experience difficulties that
could delay or prevent the successful development, introduction, manufacture and
marketing of these products (especially in light of the increasing design and
manufacturing complexities associated with the integration of technologies), or
that its new products and product enhancements will adequately meet the
requirements of the marketplace and achieve market acceptance. The Company's
business, operating results and financial condition may be materially and
adversely affected if the Company encounters delays in developing or introducing
new products or product enhancements or if such product enhancements do not gain
market acceptance. In order to maintain a competitive position, the Company must
also continue to enhance its existing products and there is no assurance that it
will be able to do so. A major portion of future revenues is expected to come
from new products and services. The Company cannot determine the ultimate effect
that new products will have on its revenues or earnings.

<PAGE>   11
 
COMPETITION
 
     The networking industry is highly competitive and competition is expected
to intensify. There are numerous companies competing in various segments of the
network management and remote access markets. Competitors include Ascend
Communications, Shiva Corporation, Cisco Systems, Inc., U.S. Robotics
Corporation, Microcom, Inc. and Bay, among others. Many of the Company's
competitors have greater name recognition, more extensive engineering,
manufacturing and marketing capabilities and greater financial, technological
and personnel resources than those available to the Company. In addition,
certain companies in the networking industry have expanded their product lines
or technologies in recent years as a result of acquisitions. There can be no
assurance that the Company will be able to compete successfully in the future
with existing or new competitors.
 
PRODUCT PROTECTION AND INTELLECTUAL PROPERTY
 
     The Company, like many other companies in the network access industry,
anticipates it will rely upon rights granted through licenses from third parties
for a substantial amount of proprietary information used to develop its
products; however, some companies may determine not to grant such licenses and
may seek to protect their proprietary rights in such technological information.
Accordingly, there can be no assurance that the Company will be able to continue
obtaining additional rights to utilize proprietary technological information
necessary to develop its products. Because of the existence of a large number of
patents in the networking field and the rapid rate of issuance of new patents,
it is not economically practical to determine in advance whether a product or
any of its components infringe patent rights of others. In the event of any
infringement, the Company believes that, based upon industry practice, necessary
licenses or rights under such patents may be obtained on terms that should not
have a material adverse effect on the Company's consolidated financial position
or results of operations. However, there can be no assurance in this regard.
 
CERTAIN ANTITAKEOVER EFFECTS
 
   
     The Company's Restated Certificate of Incorporation (the "Company
Certificate") includes certain provisions that are intended to prevent or delay
the acquisition of the Company by means of a tender offer, proxy contest or
otherwise. Specifically, the Company Certificate provides for a classified Board
of Directors, classified into three classes with terms of three years each. In
addition, the Company Certificate authorizes the Board of Directors of the
Company to issue preferred stock without further stockholder approval, which
could have dividend, redemption, liquidation, conversion, voting or other rights
that could adversely affect the voting power or other rights of the holders of
Company Stock. Finally, the Company is subject to Section 203 of the Delaware
General Corporation Law (the "DGCL") which limits transactions between a
publicly held company and "interested stockholders" (generally those
stockholders who, together with their affiliates and associates, own 15% or more
of a company's outstanding capital stock). Any one of, or a combination of, the
above anti-takeover provisions could discourage a third party from attempting to
acquire control of the Company. See "Description of Capital Stock." The
Company's 1996 Long-Term Incentive Plan and the Company's 1996 Non-Employee
Directors' Stock Option Plan will provide for acceleration of stock options and
restricted stock awards upon a change in control of the Company, which will have
the effect of making an acquisition of control of the Company more expensive.
See "Management -- Company Benefit Plans." These plans may also inhibit a change
in control of the Company. In addition, certain Company officers will have
severance compensation agreements with the Company that will provide for
substantial cash payments and acceleration of other benefits in the event of
specified corporate changes related to the Company, including a change in
control of the Company. See "Management -- Employment and Consulting
Agreements."
    
 
IMPORTANT CONSIDERATIONS RELATED TO FORWARD-LOOKING STATEMENTS
 
     With the exception of historical information, the matters discussed in this
document may include forward-looking statements that involve risks and
uncertainties. The Company wishes to caution readers that a number of important
factors, including those identified in this section as well as factors discussed
elsewhere in this filing and in other filings with the Commission, could affect
the Company's actual results and cause actual results to differ materially from
those in the forward-looking statements.

DIVIDENDS
 
     The Company does not anticipate paying dividends for the foreseeable
future.
 
CERTAIN TAX CONSIDERATIONS
 
     As described below, the Board of Directors of Penril has received an
opinion from its tax counsel to the effect that, on the basis of the facts,
representations and assumptions set forth in the opinion, for federal income tax
purposes, it is more likely than not that (i) the Distribution will qualify as a
tax-free spin-off pursuant to Section 355 of the Code and (ii) the Merger will
qualify as a reorganization within the meaning of Section 368(a)(1)(B) of the
Code. No ruling from the IRS to that effect has been or will be sought. If the
tax-free nature of the Merger is invalidated, it would reduce the likelihood
that the Distribution will qualify as a tax-free spin-off pursuant to Section
355 of the Code. See "The Distribution -- Certain Federal Income Tax
Consequences of the Distribution." If the Distribution were not to qualify for
tax-free treatment under Section 355 of the Code, then, in general, although not
entirely free from doubt, for federal income tax purposes it is likely that each
Penril stockholder would be required to recognize income or gain on the receipt
of Company Stock in the Distribution in an amount up to the fair market value of
the shares of Company Stock received in the Distribution. Each member of the
Penril consolidated group (including the Company and its subsidiaries) would
remain jointly and severally liable for any tax liability of Penril or its
subsidiary incurred prior to the Merger.
 
RELATIONSHIP WITH PENRIL
 
   
     The Company does not have an operating history as an independent public
company. The operations of the Company historically have relied on the rest of
Penril for certain necessary administrative services. As of the Distribution
Date, Penril and the Company will enter into several agreements for purposes of
governing certain of the ongoing relationships between the two companies
following the Distribution, including indemnification obligations. Pursuant to
the Indemnification Agreement to be entered into between Penril and the Company
in connection with the Transfer (the "Indemnification Agreement"), the Company
will agree to indemnify Penril against all expenses and liabilities resulting
from (i) the operation of the Company from and after the Distribution, (ii)
Penril's operations prior to the Transfer other than those based upon, arising
out of or in connection with (a) the Modem Business, (b) the Merger and
transactions relating to the Merger or (c) the tax consequences of the
Distribution, (iii) the termination of employment of employees (other than those
employees identified as remaining with Penril after the Transfer) by Penril or
(iv) information furnished by Penril or the Company relating to the Company
contained in the Registration Statement filed by Bay in connection with the
Proxy Statement/Prospectus. Included within the potential liabilities against
which the Company will indemnify Penril are those referred to in "Business-Legal
Proceedings". Although the Company is not aware of any pending or threatened
material liability for which the Company anticipates becoming obligated to make
payments in connection with its obligation to indemnify Penril except for
possible payments resulting from the termination of employment of certain
employees (which payments management anticipates will not exceed approximately
$400,000), there can be no assurance that such indemnification obligations could
not arise or that such indemnification obligations would not be material to the
Company. These agreements were negotiated while the Company was owned by Penril
and consequently are not the result of arm's-length negotiations between
independent parties. Nonetheless, the Company believes that the agreements are
fair to the parties and contain terms which are generally comparable to those
which would result from arm's-length negotiations, although there can be no
assurance thereof.
    
 
                                THE DISTRIBUTION
 
   
BACKGROUND OF THE TRANSFER AND THE DISTRIBUTION
    
 
   
     Because the Modem Business was all that Bay desired to acquire, Penril
determined to effect the Distribution, which is intended to be tax-free to
Penril stockholders for federal income tax purposes and which was a condition to
Bay's willingness to enter into the Merger Agreement. Penril believes the
Distribution will enable Penril stockholders to participate in the values and
prospects of the assets and business of the Company.
    
 
                                       11
<PAGE>   13
 
   
     Although the Transfer and Distribution will not be effected unless the
Merger is approved and is about to occur, the Transfer and Distribution are
separate from the Merger and the Company Stock to be received by holders of
Penril Stock in the Distribution does not constitute a part of the consideration
to be received in the Merger.
    
 
   
     Until shortly before the Merger, the Company will own no material assets
and will conduct no significant business activity. Prior to the Merger, Penril
and the Company will enter into a Distribution Agreement and an Indemnification
Agreement pursuant to which agreements Penril will transfer to the Company as a
capital contribution all of Penril's right, title and interest in the Remote
Access Business and all of the other assets of Penril unrelated to the Modem
Business, as well as a portion of Penril's total net operating loss
carryforward; and the Company will (a) assume, pay, perform and discharge all of
the liabilities of Penril other than (i) liabilities relating to the Modem
Business; and (ii) the bank debt of Penril (which may not exceed $4,000,000 at
the Effective Time); and (b) indemnify Penril for any and all claims and
liabilities arising as a result of or in connection with the sale by Penril (if
consummated prior to the Distribution) of either Technipower or EMI. At the time
of the Transfer, Penril will own all of the Company's outstanding stock. See
"Certain Transactions."
    
 
MANNER OF EFFECTING THE DISTRIBUTION
 
     Pursuant to the Distribution, Penril will distribute as a dividend to its
stockholders of record as of the Record Date ("Holders") one share of Company
Stock for each share of Penril Stock then held. On the Distribution Date, Penril
will deliver to Continental Stock Transfer & Trust Company, as distribution
agent, certificates evidencing all of the issued and outstanding shares of
Company Stock owned by Penril, which will represent all of the issued and
outstanding shares of Company Stock. All shares of Company Stock distributed
will be fully paid, nonassessable and free of preemptive rights.
 
   
     As a result of the Distribution, all of the issued and outstanding shares
of Company Stock will be distributed to Holders. The Record Date is expected to
be on or about November 15, 1996 and the Distribution Date will be on or about
November 19, 1996. It is presently anticipated that certificates representing
Company Stock will be mailed to Holders on or about the Distribution Date. After
the Distribution Date, Holders will hold their Penril Stock (until converted
into Bay Stock) as well as Company Stock. The Distribution will not affect the
number of, or the rights attaching to, outstanding shares of Penril Stock.
    
 
     No Holder will be required to pay any cash or other consideration for the
shares of Company Stock received in the Distribution nor will any action be
required to be taken by any Holder, including tendering stock certificates, in
order to receive shares of Company Stock. Penril has accounted for the
Distribution as a dividend and has reduced its stockholders' equity by the net
book value of the Company Stock distributed.
 
     IN ORDER TO BE ENTITLED TO RECEIVE THE DISTRIBUTION OF COMPANY STOCK, A
PENRIL STOCKHOLDER RECEIVING THIS PROSPECTUS MUST HAVE BEEN A HOLDER OF RECORD
OF PENRIL STOCK ON THE RECORD DATE.
 
LISTING AND TRADING OF COMPANY STOCK
 
   
     The Company has applied to have the Company Stock listed for trading on
Nasdaq under the symbol "ACCB". The transfer agent and registrar for the Company
Stock is Continental Stock Transfer & Trust Company.
    
 
     No current public trading market for the Company Stock exists, although a
"when-issued" market could develop several days prior to the Distribution Date.
The extent of the market for the Company Stock and the prices at which the
Company Stock may trade prior to or after the Distribution cannot be predicted.
See "Risk Factors -- Absence of Trading Market for Company Stock."
 
     The Company Stock distributed to Holders will be freely transferable,
except for Company Stock received by persons who may be deemed to be
"affiliates" of the Company under the Securities Act. Persons who may be deemed
to be affiliates of the Company after the Distribution generally include
individuals or entities that control, are controlled by or are under common
control with the Company and may include
 
                                       12
<PAGE>   14
 
certain officers and directors of the Company as well as principal stockholders
of the Company. Persons who are affiliates of the Company will be permitted to
sell their Company Stock only pursuant to an effective registration statement
under the Securities Act or an exemption from the registration requirements of
the Securities Act, such as the exemptions provided by Section 4(2) of the
Securities Act or Rule 144 thereunder. It is not expected that Rule 144 will be
available for the sale of Company Stock by affiliates of the Company until at
least 90 days after the effectiveness of the Company's registration statement
registering Company Stock under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"). See "Description of Capital Stock -- Company Stock."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE DISTRIBUTION
 
     General. The following is a summary of the material federal income tax
consequences of the Distribution to the holders of shares of Penril Stock. The
federal income tax discussion set forth below is for general information only
and may not apply to particular categories of holders of shares of Penril Stock
subject to special treatment under the Code, including without limitation,
foreign holders and holders whose Penril securities were acquired pursuant to
the exercise of any employee stock option or otherwise as compensation. EACH
HOLDER OF SHARES OF PENRIL STOCK AND PENRIL OPTIONS IS URGED TO CONSULT HIS TAX
ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES TO HIM OF THE DISTRIBUTION,
INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL AND FOREIGN INCOME AND
OTHER TAX LAWS.
 
   
     Consequences of Proposed Transaction. As described in the Summary, the
Distribution is being made in preparation for, and in conjunction with, the
Merger. The Board of Directors of Penril has received an opinion from its
counsel Benesch, Friedlander, Coplan & Aronoff P.L.L. ("Counsel") to the effect
that, on the basis of the facts, representations and assumptions set forth in
the opinion, for federal income tax purposes, it is more likely than not that
(i) the Distribution will qualify as a tax-free spin-off pursuant to Section 355
of the Code and (ii) the Merger will qualify as a reorganization within the
meaning of Section 368(a)(1)(B) of the Code. If the tax-free nature of the
Merger is invalidated, it would reduce the likelihood that the Distribution will
qualify as a tax-free spin-off pursuant to Section 355 of the Code.
    
 
     The representations (among others) relied upon by Counsel in giving its
opinion contain statements or agreements to the effect that: the Modem Business
and Remote Access Business have each been actively conducted for five years and
will continue to be conducted as separate, active businesses after the proposed
transactions; certain transactions between Penril and Bay in effect prior to the
closing of the Distribution and the Merger are fair market value transactions
entered into for valid business reasons independent of the Merger, and all of
the transactions between the Company and Bay or Penril in effect after the
closing of the Distribution and the Merger (other than certain contributions
made to the Company by Penril prior to the Distribution) will also be fair
market value transactions entered into for valid business reasons; the transfer
of certain cash and liquid assets to the Company (and the retention of certain
debt by Penril) is necessitated by the ongoing business needs of the Company;
the liquid assets being received by the Company will be used in the operation of
its Remote Access Business and will not be used to make distributions to, or
redeem the shares of Company Stock held by stockholders of the Company; Penril
will be maintained as a separate corporation by Bay; and Bay owns no Penril
Stock and has no intention to reacquire any stock issued in the Merger.
 
     The favorable tax treatment of both the Distribution and the Merger also
depends upon the historic stockholders of Penril maintaining a so-called
"continuity of interest" in both the Bay Stock received in the Merger and the
Company Stock received in the Distribution. Under Revenue Procedures issued by
the IRS, continuity of interest is maintained in each transaction if the
historic stockholders of Penril continue to maintain at least one-half their
stock investment in Penril in the modified form of each of the Company Stock and
Bay Stock received by them in the proposed transactions. Penril has represented
that it knows of no plan or intent by any stockholder to sell more than one-half
of his Bay Stock or Company Stock received in the proposed transactions. There
are no court cases or published rulings by the Service giving guidance on how to
measure the continuity of interest of historic stockholders in publicly owned
corporations, such as Penril, where 5% stockholders own, in the aggregate, less
than 50% of the stock of the corporation. However, Counsel
 
                                       13
<PAGE>   15
 
   
is of the opinion, based upon Penril's representations regarding the plans and
intentions of its stockholders, that both the Distribution and the Merger meet
the continuity of interest requirement. It should be noted that Penril has not
sought representations (as required by the IRS from taxpayers seeking private
letter rulings in reorganizations) from each of its 5% stockholders as to their
plans and intentions with respect to their Penril Stock or the Bay Stock and the
Company Stock to be received in the proposed transactions.
    
 
   
     Consequences of the Distribution to Penril Stockholders. If the
distribution qualifies as a tax-free spin-off for federal income tax purposes:
    
 
          1. A Penril stockholder will not recognize any income, gain or loss in
     connection with the Distribution.
 
          2. Following the Distribution, a Penril stockholder will apportion the
     tax basis for his shares of Penril Stock between such Penril Stock and the
     Company Stock received in the Distribution in proportion to the relative
     fair market values of such Penril Stock and Company Stock on the
     Distribution Date. A Penril stockholder's holding period for the Company
     Stock received or deemed received in the Distribution will include the
     period during which such stockholder held the Penril Stock with respect to
     which the Company Stock was received or deemed received, provided that such
     Penril Stock is held as a capital asset by such stockholder as of the time
     of the Distribution.
 
   
     Counsel's opinion with respect to the Distribution is based upon certain
representations and assumptions and represents Counsel's best legal judgment,
and is not binding upon the IRS or the courts. If any representation or
assumption relied upon in rendering Counsel's opinion is inaccurate, or if the
IRS were to challenge successfully the federal income tax treatment of the
Distribution set forth in Counsel's opinion, then, in general, although not
entirely free from doubt, for federal income tax purposes it is likely that each
Penril stockholder would be required to recognize income or gain on the receipt
of the shares of Company Stock in the Distribution in an amount up to the fair
market value of the shares of Company Stock received in the Distribution. In
such event (a) the tax basis of the shares of Company Stock received by a Penril
stockholder in the Distribution would be the fair market value of such shares on
the date the Distribution is consummated and (b) the holding period for such
shares of Company Stock would begin the day after the date the Distribution is
consummated.
    
 
     Current treasury regulations require that each Penril stockholder who
receives Company Stock pursuant to the Distribution attach to his federal income
tax return for the year in which the Distribution occurs a detailed statement
setting forth such information as may be appropriate in order to demonstrate the
applicability of Section 355 of the Code to the Distribution. Penril or its
successor, Bay, will convey the appropriate information to each Penril
stockholder of record as of the Record Date.
 
CERTAIN CONSEQUENCES OF THE DISTRIBUTION
 
   
     After the Distribution, Penril stockholders of record as of the Record Date
and the Effective Time will own two securities (shares of Penril Stock, until
they are converted into shares of Bay Stock, and shares of Company Stock) and
will be able to increase or decrease their respective holdings in either Bay or
the Company without affecting their holdings in the other company. The Company
will be an independent, publicly traded company, owning and operating the Remote
Access Business and, if not disposed of prior to the Distribution, Technipower
and EMI.
    
 
REASON FOR FURNISHING THIS PROSPECTUS
 
     This Prospectus is being prepared in order to provide information for
Holders, each of whom will receive shares of Company Stock in the Distribution.
It is not to be construed as an inducement or encouragement to buy or sell any
securities of Penril, the Company or any other corporation. The information
contained herein is provided as of the date of this Prospectus unless otherwise
indicated. Neither Penril nor the Company will update the information contained
in this Prospectus to effect any changes that may occur subsequent to the date
hereof, except in the normal course of their respective public disclosure
practices.

     The capitalization of the Company following the Distribution will reflect
the net book value of the assets transferred to and the liabilities assumed by
the Company from Penril in connection with the Transfer. The following table
sets forth the proforma adjusted capitalization of the Company at July 31, 1996.
This table has been prepared based upon the historical consolidated balance
sheet of Penril as of July 31, 1996 giving effect to the Transfer and the
Distribution. This table also reflects adjustments to the proforma
capitalization, as referred to in the note following the table. This table does
not reflect results of operations from and after July 31, 1996. This table

                 SELECTED PROFORMA CONSOLIDATED FINANCIAL DATA
    
 
   
     While the Transfer and the Distribution will take place as described above,
the following unaudited pro forma financial statements have been prepared from
Penril's historical financial statements to show the Modem Business being sold
to Bay as a pro forma adjustment and the Company, on a proforma basis, as the
continuing entity.
    
 
   
     With the exception of historical information, the matters discussed in this
section include forward-looking statements that involve risks and uncertainties.
The Company wishes to caution readers that a number of important factors,
including those identified in this section as well as factors discussed in "Risk
Factors" and elsewhere in this Prospectus, could affect the Company's actual
results and cause actual results to differ materially from those in the
forward-looking statements.
    
 
PROFORMA BALANCE SHEET
 
   
     The following unaudited proforma consolidated balance sheet for the Company
has been prepared based upon the historical consolidated balance sheet for
Penril as of July 31, 1996 and giving effect to the Transfer and the
Distribution and the events that are directly attributable to those
transactions. In the opinion of Penril's management, all material adjustments
necessary to reflect the effects of the Transfer and the Distribution have been
made. Such unaudited proforma information should be read in conjunction with
Penril's financial statements and the notes thereto included elsewhere in this
Prospectus.
    
 
   
     The unaudited proforma consolidated balance sheet has been prepared based
upon assumptions deemed appropriate by the management of Penril, does not
purport to represent what the actual financial position would have been if the
Transfer and the Distribution had been consummated at July 31, 1996, may not be
indicative of actual results and does not purport to represent the future
financial position of the Company.

PROFORMA STATEMENTS OF OPERATIONS
    
 
   
     The following unaudited proforma consolidated statement of operations for
the Company has been prepared from the historical results of operations of
Penril. The proforma adjustments have been computed assuming the Transfer and
the Distribution had been consummated August 1, 1995. This statement should be
read in conjunction with the historical financial statements of Penril including
the notes thereto, which are
    
 
                                       17

included elsewhere in this Prospectus, the unaudited proforma consolidated
balance sheet appearing above and the notes to this unaudited proforma
consolidated statement of operations.
    
 
   
     The unaudited proforma consolidated statement of operations has been
prepared based upon an identification of those costs that could be directly
attributed to the Modem Business. Expenses which were not specifically
identified with either the Modem Business or the Remote Access Business remain
with the Company; consequently the expenses shown for the Company are in excess
of those that would have been incurred had the Company been a stand alone
company. This statement does not purport to represent what the actual results of
operations would have been for the Company had the Transfer and the Distribution
been consummated at the beginning of the period, is not indicative of actual
results and does not purport to represent what the results of operations of the
Company may be for future periods.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
    
   
                RESULTS OF OPERATIONS OF PENRIL AND THE COMPANY
    
 
   
GENERAL BUSINESS DEVELOPMENTS
    
 
   
     Beginning in fiscal year 1994, Penril began to focus its business on remote
access connectivity products. Out of this strategy came Penril's new Remote
Access Business. The first phase of the new Remote Access Business includes the
Ram Rack and the Access Beyond 1000 Remote Access Server.
    
 
   
     As part of this strategy, Penril's Board of Directors made the decision to
sell EMI and consequently, EMI has been classified as a discontinued business.
Penril continues to operate EMI and expects EMI to operate at least at a
break-even level through the anticipated disposition date, which Penril's
management believes will be completed by December 31, 1996. Prior to the end of
fiscal 1996, Penril entered into an agreement, subject to certain contingencies,
to sell Technipower. The completion of the sale is expected during the first
quarter of fiscal 1997. Penril recorded a charge of $640,000 in the fourth
quarter of fiscal 1996 for the estimated loss on disposal of both these
businesses. No assurance can be given that either or both of EMI and Technipower
will be sold or that the timing or terms of any such sale will be favorable to
and as anticipated by Penril.
    
 
   
     On June 16, 1996, as amended August 5, 1996, Penril entered into the Merger
Agreement with Bay and a subsidiary of Bay. Under the terms of the Merger
Agreement, Penril will transfer all of its Remote Access Business and any other
assets unrelated to the Modem Business to the Company and then distribute all of
the shares of Company Stock to Penril's stockholders. Following the Transfer and
the Distribution, the subsidiary of Bay will merge with and into Penril, whose
primary remaining operations will consist of the Modem Business, with Penril
becoming a wholly owned subsidiary of Bay.
    
 
   
     As a result of all of the above items, 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 to improve
competitiveness for the long term. This restructuring plan includes the
elimination of the VCP and BRX product lines and the introduction of the new
Remote Access Business. The decision to restructure and refocus is not dependent
upon consummation of the Merger. As a result of this decision to restructure the
business, Penril recorded a charge in the fourth quarter of fiscal 1996 of $9.7
million. This charge consisted of a write-down of costs in excess of net assets
acquired ($5.0 million), a provision for costs associated with contractual
obligations for leased facilities in Hong Kong and Carlstadt, New Jersey ($1.0
million), a provision for the write-down of purchased technology ($1.0 million),
a provision for the write-down of inventories and fixed assets ($2.3 million),
and a provision for costs associated with termination of approximately 90
employees ($400,000).
    
 
   
     On an annualized basis this plan is expected to reduce labor costs by
approximately $3 million, reduce amortization and depreciation expenses by
approximately $700,000, and reduce facilities expenses by approximately
$300,000. The Company anticipates completion of the employee terminations and
consolidation of leased facilities by the end of the second quarter of fiscal
1997, and does not anticipate any additional costs associated with this
restructuring plan.
    
 
   
     With the exception of historical information, the matters discussed in this
section include forward-looking statements that involve risks and uncertainties.
The Company wishes to caution readers that a number of important factors,
including those identified in this section as well as factors discussed in "Risk
Factors" and elsewhere in this Prospectus, could affect the Company's actual
results and cause actual results to differ materially from those in the
forward-looking statements.
    
 
   
NEW ACCOUNTING PRONOUNCEMENTS
    
 
   
     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
    
 
                                       19
<PAGE>   21
 
   
fiscal 1996, the Company decided to restructure and refocus its remaining
businesses. Due to these events, the Company determined that the excess of costs
over net assets acquired would not be recoverable, and a charge of $5.0 million
was taken in the fourth quarter of fiscal 1996 against the carrying value of
this asset. This charge was the remaining balance in the account "Excess of
Costs over Fair Value of Net Assets Acquired."
    
 
   
     During fiscal 1996, Statement of Financial Accounting Standard No. 123
("SFAS 123"), "Accounting for Stock Based Compensation," which establishes a
fair value based method for stock-based compensation plans, was issued. SFAS 123
includes both recognition and measurement provisions and disclosure requirements
for stock based compensation. The Company has elected not to adopt the
recognition and measurement provisions of SFAS 123. The effect of adopting this
statement in fiscal 1997 is not deemed to be material.
    
 
   
RESULTS OF OPERATIONS
    
 
   
     As a result of the Merger Agreement with Bay and the spin-off of the LAN
and Host Access products business in the Transfer, the following discussion is
based on the Penril historical financial statements, with revenues and expenses
which could be specifically identified with the modem products shown separately
from the LAN and Host Access products. All revenues and expenses which could not
be specifically identified with the modem products were included with the LAN
and Host Access products, consequently the expenses for the LAN and Host Access
products are in excess of those that would have been incurred had the Company
been a stand alone company. As noted above, Technipower and EMI are classified
as discontinued operations and are not included in this discussion unless
otherwise noted. Dollar amounts are reported in thousands.

     The decrease in revenues for Penril's LAN and Host Access 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. The Company intends to phase out these products, which represent older
technology, and introduce its new Remote Access Business. The new Remote Access
Business is designed to meet the growing demand for remote access technology.
The Company believes that its new Remote Access Business has a unique product
architecture that combines both remote access and internetworking capabilities
which will offer expanded and fully compatible capabilities to the existing
customer base as well as offering new customers a product line which will be
state of the art in remote access. The Company believes that this new Remote
Access Business will be competitively priced and will generate revenues over the
next fiscal year to offset the decline in revenue from its older LAN and Host
Access products.
    
 
   
     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 its modem technology, and Penril was paid $4.5 million. Revenues for
the Modem Business without this license agreement would have been $15,019,000 in
fiscal 1996 compared with $18,974,000 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. The
Company believes that more competitive pricing of its new V.34 modems will
result in higher revenues for fiscal 1997 compared to fiscal 1996, and that
these higher revenues should offset the continued decline in sales of older
modem products.
    
 
   
     Exports represented 44% of Penril's total revenues in fiscal 1996 and 45%
of Penril's revenues in fiscal 1995. Approximately 60% of Penril's exports
related to modem products in both fiscal 1996 and fiscal 1995. Revenues from
Penril's foreign subsidiaries, which are primarily sales and marketing
operations (in England and Hong Kong) represented 7% of Penril's total revenues
in fiscal 1996 and 5% of Penril's total revenues in

fiscal 1995 and over 95% of those revenues were generated from the subsidiary in
England. Due to the growing demand worldwide for data communications products,
Penril believes it will continue to generate revenue from exports of both its
LAN and Host Access products and its modem products. Because of the location of
its primary foreign subsidiary, Penril does not believe it has any significant
exposure to exchange rate risk.
    
 
   
     As a result of the restructuring plan, the Hong Kong subsidiary will be
phased out in fiscal 1997, and sales and marketing operations will be performed
from the U.S. Penril does not anticipate that the restructuring plan will have a
material effect on revenues for either the modem products or the LAN and Host
Access products.

</TABLE>
    
 
   
     The decrease in the gross profit margins for LAN and Host Access 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.

</TABLE>
 
   
     Selling, general and administrative expenses decreased for the LAN and Host
Access 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 Merger. All
expenses which could not be specifically identified with the modem products were
included with the LAN and Host Access products, consequently the expenses for
the LAN and Host Access products are in excess of those that would have been
incurred had the Company been a stand alone company.

     The decrease in revenues for Penril's LAN and Host Access products was
primarily attributable to the declining market for terminal servers and
multiplexers as these products were reaching the end of the product life cycle,
and to a decrease in orders from some of Penril's OEM customers. The decrease in
revenues from modem products was due to unexpected delays in shipment of the
V.34 and V.34bis modems. Part of this delay resulted in a decline in total
exports to $23.6 million in fiscal 1995 from $25.6 million in fiscal 1994.

     Interest expense increased because of the increase in the prime rate from

its principal bank was raised from prime plus 1/2% to prime plus 2%.
    
 
   
LIQUIDITY AND CAPITAL RESOURCES
    
 
   
     During fiscal 1996, Penril sold 2,607,000 shares of Penril Stock in two
unrelated series of private placements which generated aggregate proceeds of
$14,744,000. The aggregate proceeds were used to repay all of Penril's bank term
debt and all its outstanding subordinated debt, which together totaled $4.8
million, and to fund general working capital needs including the loss of $11.1
million (excluding restructuring charges) for fiscal 1996.
    
 
   
     As a result of the strategic business plan to restructure Penril, Penril
recorded a restructuring charge of $9.7 million in the fourth quarter of fiscal
1996. This restructuring charge included non-cash items for the write-down of
costs in excess of net assets acquired ($5.0 million), a provision for the
write-down of purchased technology ($1.0 million) and a provision for the
write-down of inventory ($2.2 million). This restructuring charge also included
items that will require future cash expenditures by the Company for employee
severance ($400,000) and obligations for leased facilities ($1.0 million). The
severance payments to employees will occur in the fiscal 1997 second quarter and
the payments under the leased facilities obligations will occur over the
remaining life of the lease with $282,000 due in fiscal 1997, $289,000 due in
fiscal 1998 and $440,000 due after fiscal 1998.
    
 
   
     As a result of lower than expected sales and the buildup of inventory to
support the new Remote Access Business, inventory levels of Penril increased
$1.3 million during the first nine months of fiscal 1996. Consequently, Penril
started a program to reduce inventories that resulted in a fourth quarter
reduction of approximately $750,000. In addition, as noted above, Penril
recorded an inventory write-down provision of $2.2 million as part of the
restructuring charge. These actions resulted in Penril's inventory levels
declining to $9.7 million at July 31, 1996, or a reduction of $1.7 million below
the July 31, 1995 inventory level of $11.4 million.
    
 
   
     Contributing to Penril's cash flow in fiscal 1996 was a reduction in
accounts receivable of $6.5 million. This reduction was the result of the lower
sales volumes in fiscal 1996 compared to fiscal 1995 and an aggressive
collection effort that reduced the average collection time from 94 days in
fiscal 1995 to 65 days in fiscal 1996.
    
 
   
     Penril's accounts payable declined by $2.1 million, also as a result of the
lower level of business.
    
 
   
     As part of the Transfer, the Company is to receive all the cash and cash
equivalents of Penril. As of September 25, 1996, Penril had cash and cash
equivalents of approximately $3.8 million. In addition, Penril is expected to
generate cash from several non-operating sources. These anticipated sources
include the following:
    
 
   
          Penril settled a law suit with Standard Micro Systems Corp. on
     September 24, 1996. This settlement will result in Penril receiving, in
     October 1996, $3.5 million in cash after all related expenses have been
     paid.
    
 
   
          Penril has entered into a contract to sell Technipower for $4.3
     million, subject to various contingencies. Penril expects this transaction
     to close during the first quarter of fiscal 1997 with the payment to Penril
     of $1.5 million in cash. The remaining $2.8 million payment is due,
     pursuant to the terms of the contract, on or prior to December 31, 1996.
    
 
   
          Penril is in discussions with a potential buyer of EMI. Although there
     can be no assurance that a sale of EMI will occur, Penril's management
     believes that the sale of EMI will be completed by December 31, 1996 with
     expected net cash proceeds of $3.0 million to $3.5 million after
     transaction expenses.

     As part of the Merger Agreement with Bay, the Company will receive $1.5
million at the closing pursuant to the Transitional Services Agreement with
Penril.
    
 
   
     Prior to the Distribution, Penril also anticipates receiving approximately
$5 million from the exercise of employee and non-employee director stock
options. Of this amount, approximately $2.9 million is anticipated to be
received from certain officers of the Company and from certain directors of
Penril, each of whom has advised Penril of his intention to exercise all of his
stock options. The cash generated from the exercises is expected to be used for
the expenditures related to the Merger and the Transfer. These expenditures
include legal and accounting fees of approximately $650,000, investment banker
fees of approximately $1.3 million and change of control payments due to certain
officers of Penril of $1.3 million.
    
 
   
     Penril currently has a line of credit with its principal bank. The
agreement provides a maximum working capital facility of $5.5 million with
borrowing based on qualified accounts receivable and secured by substantially
all of Penril's assets. Interest accrues at the bank's prime rate plus 2% with a
commitment fee of  3/8% on the unused portion of the facility. In the event the
facility is canceled prior to its expiration, there is a fee due the bank equal
to 3% of the total facility. As of July 31, 1996, Penril had borrowed $4 million
under the line and had utilized another $90,000 in connection with a standby
letter of credit. Pursuant to the Merger Agreement, after the Merger Penril will
retain bank debt up to a maximum of $4 million.
    
 
   
     Currently there are discussions with lending institutions regarding a line
of credit for the Company after the Transfer. Management believes the Company
will be able to secure a line of credit after the Transfer, although there can
be no assurances that a line of credit will be secured, and if secured will be
on economic terms favorable to the Company.
    
 
   
     Penril's management believes that during the first 12 months following the
Distribution the Company will have cash expenditures of approximately $2.2
million for fixed assets and capitalized technology purchases and $700,000
related to the employee severance and lease obligations noted above.
    
 
   
     Immediately following the Distribution, management believes the Company
could have $7.8 million in cash as well as the right to receive a payment of
$2.8 million from the sale of Technipower and possibly proceeds from the sale of
EMI. Based on the Company's expectation with respect to product development and
production, the Company's cash from operations alone will not satisfy the
Company's cash requirements during the first 12 months following the
Distribution. However, the Company expects that cash on hand as noted above,
cash from operations and cash from the sources discussed above, will satisfy the
Company's cash requirements during the first 12 months after the Distribution.
There can be no assurance that product development will proceed at the expected
pace, that the Company's sales will achieve expected levels, that staffing and
facilities required will be able to be maintained at the reduced levels expected
under the restructuring plan referred to above, or that other competitive
factors will not result in cash from operations being less than expected by
management. However, the Company has the ability to defer product development
and marketing expenditures if necessary, to match with cash flow. The deferral
of these expenditures could have a negative impact on future sales of the
Company's products. The Company believes, based on its expected cash on hand,
cash from operations, cash from the sources discussed above and the anticipated
bank line of credit, that there will be adequate cash flow to fund the Company's
operations.
    
 
                                    BUSINESS
 
GENERAL
 
   
     The Company, which is a wholly-owned subsidiary of Penril, was recently
formed by Penril solely for the purpose of effecting the Merger and the
Distribution. Until shortly before the Merger, the Company will own no material
assets and will not conduct any business activities other than in connection
with the Distribution and the Merger. Prior to the Merger, Penril will transfer
to the Company, as a capital contribution, all of the right, title and interest
in all of Penril's Remote Access Business and all other businesses and assets
and corresponding liabilities of Penril unrelated to the Modem Business. Upon
consummation of the Merger, a subsidiary of Bay will merge with and into Penril,
Penril will become a wholly-owned subsidiary of Bay, and the Company will
continue with its own separate corporate existence unaffiliated with Penril.

     While the Company is a newly formed corporate entity, the Remote Access
Business to be contributed to the Company by Penril has an operating history
consisting of the development and sales of LAN and Host Access products and the
development of a new product family called Access Beyond. In connection with the
Remote Access Business, the Company engages in the development and marketing of
network access devices which enable local, remote or mobile users to access
network resources located at remote sites, central sites or any other point in
the network.
    
 
PRODUCTS
 
     The Company's product line consists largely of products which serve the LAN
and Host Access markets and a new product family called Access Beyond, serving
the remote access market.
 
     The LAN and Host Access products currently sold by the Company include
statistical multiplexers and host access servers (VCX), Ethernet terminal
servers (CSX), Ethernet local and remote bridge routers (BRX), and a line of
CSU/DSU wide area products. The Company's new Access Beyond product family is
targeted at the remote access market, providing a scaleable, modular platform
into which a variety of connectivity options are expected to be offered. The
Access Beyond family of products is expected to replicate the function of most
of the LAN and Host Access Products, allowing the Company to phase out LAN and
Host Access Products models in favor of new Access Beyond models. Each of the
LAN and Host Access Products provides the Company with an existing revenue
stream as well as an installed base. Sales of LAN and Host Access Products will
initially provide a significant portion of the revenues of the Company.
 
     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 wide area network
("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. The BRX family includes modular switching
routers that provide up to 16 LAN ports and 2 WAN ports. A key element to the
BRX product line is in the Constellation software which provides a scaleable
router/switching solution. The Company believes that the Constellation software
uses an innovative architecture called Logical Bridge Routing, enabling network
managers to optimize bridge/router port configurations for efficient high
performance. The Constellation software is one of the key elements in the new
Access Beyond product line.
 
     The Access Beyond product line is a scaleable, modular family of remote
access products that integrate WAN transmission and LAN access technologies into
a single modular architecture, while allowing room for growth and investment
protection.
 
     The Company anticipates that a wide range of Access Beyond models will be
available to meet varying site requirements, with chassis sizes ranging from
small 4-port units to completely modular 196-port units, thus allowing the user
to customize the chassis-based units to provide a unique mix of local area and
wide area network interfaces that meet the specific demands of its network
environment. Interface options will include: Ethernet backbone and end user
ports, integrated wide area network interfaces, analog modems, digital modems,
CSU/DSU and ISDN interfaces. The modularity and scaleability of the Access
Beyond product family is intended to give the customer flexibility in network
configuration and expansion potential.
 
   
     The first phase of Access Beyond includes Ram Rack, a high density modem
product and Access Beyond 1000 Remote Access Servers, which are now being
shipped to customers. These products provide remote users with competitively
priced remote access to Novell, TCP/IP and Appletalk networks. The next phase of
the Access Beyond rollout is expected to include the Access Beyond 2400 and
Access Beyond 4400 modular chassis systems. These products are designed to
expand the flexibility of the product line with optional interfaces for direct
terminal connections, integrated V.34 modems and integrated ISDN terminal
adapters, along with LAN and high speed WAN (T1/E1/PRI) connectivity.
    
 
                                       25
<PAGE>   27
 
     The Company anticipates that future enhancements to its remote access
software will provide integration of the remote access capabilities with full
multi-protocol routing. This combination is expected to provide additional
connectivity options and reduced access costs for corporate remote access
networks by allowing a single Access Beyond server to replace several separate
competitive devices. The software features of Access Beyond are and will be
focused on solving the problems of corporate remote LAN access. With the growth
of the Internet and the World Wide Web, corporate telecommuters and traveling
employees now require simultaneous support for multiple networking protocols
allowing access to a wide variety of applications. Networking security is
provided via a collection of security options.
 
     All Access Beyond products will be monitored and configured with a
graphical, menu-driven Windows-based management tool that provides real-time
management control over the Access Beyond products. This management tool will be
based on the industry standard SNMP protocol to ensure interoperability with
equipment and management systems from other vendors.
 
     The Company believes that it will deliver the industry's first unified
approach to remote access, with one comprehensive product line that can supply
both LAN and WAN technologies required in a single architecture, with complete
management control, and new levels of investment protection for end users.
Existing applications will be changed from dedicated services to faster, lower
cost and more flexible services such as Frame Relay and Ethernet. Access Beyond
is intended to provide a migration path from these older networks to the remote
access networks of the future.
 
DISCONTINUED OPERATIONS
 
   
     Technipower. Technipower, a wholly-owned subsidiary of Penril, manufactures
uninterruptible power supplies and power regulating equipment. In July 1995, the
Penril Board decided to focus more of Penril's resources on its main business of
data communications and therefore determined to treat Technipower as a
discontinued operation. On July 16, 1996, Penril announced it had entered into
an agreement to sell Technipower subject to certain contingencies. Penril
anticipates that the sale of Technipower will be completed in the first quarter
of fiscal 1997 with a payment to Penril of approximately $1.5 million in cash at
closing and approximately $2.8 million to be paid pursuant to the agreement
prior to December 31, 1996. All liabilities related to Technipower which
otherwise would be the obligations of Penril will, from and after the Transfer,
be the obligations of the Company. In the event Technipower is not sold prior to
the Distribution, the assets and liabilities of Technipower will be contributed
to the Company as part of the Transfer.
    
 
   
     EMI. Another wholly-owned subsidiary of Penril, EMI, specializes in the
production of sophisticated high frequency electronic instrumentation equipment.
The Penril Board of Directors determined to sell EMI and therefore EMI has been
classified as a discontinued operation. Penril is in the process of selling EMI.
However, because it is unlikely that EMI will be sold prior to consummation of
the Distribution, it is anticipated that the assets and liabilities of EMI will
be contributed to the Company as part of the Transfer.
    
 
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.
 
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
 
                                       26
<PAGE>   28
 
could be obtained. The costs of such licenses may vary significantly depending
on the nature of the technology involved.
 
   
     The patents owned by EMI and Technipower include patents entitled "Fiber
Optic Connector", "Uninterruptible Power Supply", and "Guard Time Elimination in
a Time-Division Multiplexed, Active Star-coupled, Half-duplex Mode, Synchronous
Communications Network." The United States trademarks, tradenames and service
marks owned by EMI or Technipower include ELECTRO-METRICS, TECHNIPOWER, CONSTANT
POWER and MUX/ROUTER. The foreign trademarks, trade names, and service marks
owned by the Company include TECHNIPOWER in France, the United Kingdom and
Italy. These patents, trademarks, tradenames and service marks are currently
intended to be sold as part of the assets of EMI and Technipower. If the sale of
these subsidiaries are not consummated prior to the Transfer, these patents,
trademarks, tradenames, and service marks will be contributed to the Company as
part of EMI and Technipower.
    
 
   
     The United States trademarks, tradenames and service marks owned by the
Company include ACCESS BEYOND, MULTIVERTER, FORSITE and SUNUPS.
    
 
     The Company currently licenses 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 the Company whereby Bay licensed to Penril, on behalf of
the Company certain intellectual property, software, and technical know-how
relating to certain 24-port Digital Modem Cards. The agreement contemplates that
Bay will develop a 24-port Digital Modem Card for the Company, train the
Company's personnel in the underlying technology, and provide technical
assistance where necessary to permit the Company to market this digital
technology.
 
     In connection with the Transfer, Penril and the Company will enter into a
Technology License Agreement whereby Penril will license to the Company certain
intellectual property, software and technical know-how, including those relating
to a patent jointly owned by Penril and the University of Maryland. The
Technology License Agreement will also obligate Penril to use its best efforts
to obtain for the Company all rights obtained by Penril pursuant to cross
licensing agreements involving such jointly owned patent.
 
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,
the Company believes 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 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.
 
                                       27
<PAGE>   29
 
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.
    
 
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 $5,624,000 (28% of
consolidated revenues) for product development and engineering during fiscal
1996 compared to $5,520,000 (16% of consolidated revenues) in fiscal 1995 and
$6,797,000 (17% of consolidated revenues) in fiscal 1994.
    
 
PROPERTIES
 
   
     The Company's executive offices will be located in Gaithersburg, Maryland
in facilities which the Company will sublease from Penril. The overlease between
Penril and Real Estate Income Partners III is for 54,874 square feet and expires
in September 1999. The sublease between Penril and the Company will commence on
the date of the Distribution, or upon the Company's occupancy of the property,
whichever is earlier, and will provide for the sublease of all the premises with
an expiration date of September 30, 1999. The Company will assume all costs and
expenses under the overlease including rental payments. The Company's monthly
payment for rent and additional charges will be approximately $66,219. See
"Certain Transactions -- Sublease Agreement".
    
 
     The Company will lease a research and development facility in Carlstadt,
New Jersey. The lease is for approximately 44,403 square feet and expires in
September 2001. In addition to the facilities mentioned above, the Company will
also lease several sales offices throughout the United States. The Company
believes its properties will be adequate for its needs.
 
     In addition, EMI is a party to a lease for a manufacturing facility located
in Johnstown, New York containing approximately 40,400 square feet (the "EMI
Lease"). The EMI Lease expires in August 2005. Technipower is a party to a lease
for a manufacturing facility located in Danbury, Connecticut containing
 
                                       28
<PAGE>   30
 
   
approximately 30,000 square feet (the "Technipower Lease"). The Technipower
Lease expires in February 1998. In the event either EMI or Technipower is not
sold prior to the Distribution, the aforementioned lease obligations of EMI or
Technipower, as the case may be, will be contributed by Penril to Access Beyond
as part of the Transfer.
    
 
EMPLOYEES
 
   
     It is expected that the Company will employ approximately 170 employees as
of the Distribution Date. 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
will have employment contracts with certain officers, but does not have
employment contracts with its other employees. See "Management -- Employment and
Consulting Agreements".
    
 
LEGAL PROCEEDINGS
 
     Penril is involved in various claims and lawsuits incidental to its
business. The Company has assumed the liabilities which may arise out of certain
lawsuits to which Penril is a party, the more significant of which lawsuits are
discussed below. All costs, expenses, liabilities and obligations of the
litigation discussed below have been assumed by the Company and all recoveries
from such litigation will be realized by the Company. In the opinion of
management, the Company is adequately reserved against such claims and lawsuits,
and any ultimate liability arising out of such claims and lawsuits will not have
a material adverse effect on the financial condition or operations of the
Company.
 
   
     On June 1, 1993 Penril initiated a lawsuit against Standard Microsystems
Corp. ("SMC"), SMC Massachusetts, Inc., Ashraf M. Dahad and Kwabena Akufo (the
"SMC Defendants") in the Circuit Court of Maryland for Montgomery County for
breach of contract including, among other things, failure to transfer
technology, unfair competition and false representations. Penril sought relief
in an aggregate amount of approximately $50 million. The SMC Defendants
subsequently brought a counterclaim alleging fraud and breach of contract and
seeking recovery of amounts due under the contract which are alleged to be
approximately $1,650,000 in compensatory damages plus unspecified punitive
damages. In September 1996, Penril and the SMC Defendants agreed to drop the
fraud charges and to settle the contractual dispute. Penril will receive from
SMC, in settlement of the litigation, $3.5 million, net of legal payments, in
the first quarter of fiscal 1997.
    
 
   
     On December 24, 1994, Penril filed a complaint against Network Systems
Corporation of Minneapolis, Minnesota ("NSC") in the Circuit Court of Maryland
for Montgomery County. The litigation arises out of a contract in which Penril
agreed to develop certain computer hardware and software to NSC's
specifications. Penril alleges breach of contract, fraudulent inducement and
defamation and is seeking specific performance, compensatory damages of
$2,000,000 and punitive damages of $5,000,000. On March 28, 1995, NSC filed an
answer and counterclaim in which NSC alleges negligent misrepresentation, fraud
and breach of contract by Penril. NSC is seeking rescission of the contract,
restitution of monies paid by NSC to Penril, compensatory damages of $5,000,000
and punitive damages in an unspecified amount. As of September 30, 1996, the
litigation was in the discovery stage.
    
 
   
     Digital Equipment Corporation ("DEC") has claimed, through a series of
written communications, that Penril has violated DEC patents related to DEC LAT
technology. Penril has taken the position that Datability, Inc., prior to its
acquisition by Penril, had a relationship with DEC that involved the development
of LAT for which Datability has not collected. Both DEC and Penril have taken
the position that it is in the best interests of both parties to work toward a
fair resolution. As of September 30, 1996 no formal claims have been filed.

DIRECTORS AND EXECUTIVE OFFICERS
 
     Pursuant to the Company Certificate and the Company's By-laws ("By-laws"),
the Board of Directors of the Company (the "Board of Directors") is divided into
three classes with each director serving a three year term (after the initial
term). The following table sets forth certain information as to persons who will
serve as directors and executive officers of the Company after the Distribution.
The directors of Class I will hold office until the first scheduled annual
meeting of stockholders in 1997, the directors of Class II will hold office
until the annual meeting of stockholders in 1998 and the director of Class III
will hold office until the annual meeting of stockholders in 1999. Thereafter,
stockholders will elect the directors of each Class at the appropriate
succeeding annual meeting of stockholders.

                                            VideoGrafects, Inc., a multimedia communications
                                            company specializing in the production of video and
                                            computer based material, from its founding in August
                                            1992 until the Company was sold to French Bray in
                                            March 1996. Prior to founding VideoGrafects, Inc.,
                                            Ms. Perrier was a special (investing) partner with

other things, a two year term of employment, an annual salary of $175,000, an
opportunity for bonus compensation pursuant to a plan to be established by the
Board of Directors, and benefits consistent with those normally provided by the

that options to purchase 300,000 shares of Company Stock are to be granted to
Mr. Howard and that, upon a change of control of the Company, Mr. Howard will
receive a payment equal to two and one-half times his last full annual
compensation, including bonus.
    
 
   
     Also upon consummation of the Distribution, the Company anticipates that it
will enter into an employment agreement with Mr. Rose for Mr. Rose to serve as

<PAGE>   36
 
   
Employment Agreement also will provide that options to purchase 75,000 shares of
Company Stock are to be granted to Mr. Rose, that Mr. Rose will receive a
payment of between .5 to 1.0 times his base salary in the event of a change in
control of the Company, that Mr. Rose will receive between four and twelve
months notice of termination and that Mr. Rose will participate in any executive
bonus plan and other benefits consistent with those normally provided by the
Company to its executive officers.
    
 
     Upon consummation of the Distribution, an employment agreement between the
Company and Mr. Clary ("Clary Employment Agreement") will become effective. The
agreement will provide for a salary at the rate of $150,000 plus an opportunity
for bonus compensation of up to $150,000 pursuant to a plan to be established by
the Board of Directors. The term of this agreement will be terminable by either
party at will and will provide that options to purchase 125,000 shares of
Company Stock are to be granted to Mr. Clary. The agreement also will provide
for reimbursement of certain living expenses and travel expenses.
 
     Effective as of the Distribution, Henry D. Epstein will be a consultant to
the Company under the terms of a consulting agreement (the "Epstein Agreement")
between the Company and Ideonics, a financial and technology consulting firm
owned by Mr. Epstein. The Epstein Agreement will provide, among other things,
for a four year consulting term with an annual consulting fee of $137,500. In
addition, pursuant to the Epstein Agreement, the Company will provide Ideonics
with office space, secretarial assistance and health care benefits for Mr.
Epstein. Mr. Epstein is Chairman of the Board of both Penril and the Company
until the Merger and the Distribution, respectively.
 
   
     Pursuant to change of control provisions contained in current Penril
employment agreements, Penril will pay Mr. Howard, Mr. Rose and Mr. Epstein,
$562,500, $150,000 and $550,000, respectively, upon the consummation of the
Merger. The Distribution Agreement to be entered into by Penril and the Company
will confirm Penril's obligation to make these payments at or immediately prior
to the Merger.
    
 
PENRIL BENEFIT PLANS
 
   
     Retirement and Savings Plan.  Penril'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 Penril who have completed 90 days of
eligibility service ("Participants") are eligible to participate in the 401(k)
Plan. The 401(k) Plan permits, but does not require Penril to make matching
contributions. In addition, Penril 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 Penril 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. As a
part of the Transfer, the 401(k) Plan will be transferred to the Company and
active participation in the 401(k) Plan will be limited to eligible employees of
the Company. The Company intends to split up the 401(k) Plan so that the portion
of the plan representing the benefits of participants not employed by the
Company can be terminated and distributed to participants.
    
 
     The 1986 Incentive Plan of Penril.  On October 8, 1986, the Board of
Directors of Penril adopted the 1986 Incentive Plan of Penril (the "1986 Plan").
The 1986 Plan is intended to encourage officers and other key employees of
Penril to acquire or increase their ownership of Penril Stock.
 
     The 1986 Plan authorizes the grant to officers and key employees of awards
("Awards") consisting of "incentive stock options," as that term is defined
under the provisions of Section 422 of the Code, non-qualified stock options (or
a combination of the two) and restricted stock awards. There are 1,587 shares of
Penril Stock available for granting Awards under the 1986 Plan. The Stock
Option/Compensation Committee of the Board of Directors of Penril (the "Penril
Committee") administers the 1986 Plan and has sole discretion to determine those
employees to whom Awards will be granted, the number of Awards granted, the
provisions applicable to each Award and the time periods during which Awards may
be exercisable.
 
     The exercise price of each incentive stock option may not be less than the
fair market value of Penril Stock at the date of grant. Under the 1986 Plan,
fair market value is generally the closing price of Penril Stock
 
                                       35
<PAGE>   37
 
on the last business day prior to the date on which the value is to be
determined. Unless the Penril Committee determines otherwise, the option price
per share of any non-qualified stock option shall be the fair market value of
the shares of Penril Stock on the date the option is granted. The exercise price
of each incentive stock option granted to any stockholder possessing more than
10% of the combined voting power of all classes of capital stock of Penril, or,
if applicable, a parent or subsidiary of Penril, on the date of grant must not
be less than 110% of the fair market value on that date, and no such option may
be exercisable more than five years after the date of grant.
 
     Options granted are exercisable for a term of not more than ten years from
the date of grant. No employee may be granted an incentive stock option to the
extent the aggregate fair market value, as of the date of grant, of the stock
with respect to which incentive stock options are first exercisable by such
employee during any calendar year exceeds $100,000.
 
     Restricted stock awards are rights granted by the Penril Committee to
receive shares of Penril Stock subject to forfeiture and other restrictions
determined by the Penril Committee. Until the restrictions with respect to any
restricted stock award lapse, the shares will be held by Penril and may not be
sold or otherwise transferred by the employee. Except as otherwise determined by
the Penril Committee, until the restrictions lapse, the shares will be forfeited
if the employee's employment is terminated for any reason other than a "change
in control" or "trigger event," death, disability or retirement on or after the
employee's attainment of 65 years of age. Except as otherwise determined by the
Penril Committee, all restrictions will lapse upon the earliest of the death,
disability or retirement of the recipient employee on or after the employee's
attainment of 65 years of age. Unless the Penril Committee determines otherwise,
30% of the shares subject to a restricted stock award will vest on the first
anniversary of the date of the grant, 60% on the second anniversary and 100% on
the third anniversary of the grant.
 
     Awards granted under the 1986 Plan are subject to adjustment upon a
recapitalization, stock split, stock dividend, merger, reorganization,
liquidation, extraordinary dividend or other similar event affecting Penril
Stock such as the Distribution. An Award will not be transferable, other than by
will or the laws of descent and distribution or, in certain circumstances,
pursuant to a qualified domestic relations order, and an Award may be exercised,
during the lifetime of the holder of the Award, only by the holder, or the
holder's personal representative in the event of disability.
 
     In the case of a "change in control" of Penril or a "trigger event," an
option holder will generally have the right, commencing at least five days prior
to the "change in control" or "trigger event" 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 they previously have not
been exercised, without regard to any vesting limitations. On July 2, 1996, the
Penril Committee took action which caused all of the outstanding Penril options
held by directors and executive officers of Penril to vest.
 
     The 1986 Plan will terminate on October 8, 1996, and Awards will not be
granted under the 1986 Plan after that date although the terms of any Award may
be amended in accordance with the 1986 Plan at any date prior to the end of the
term of such Award. Any Awards outstanding at the time of termination of the
1986 Plan will continue in full force and effect according to the terms and
conditions of the Award and the 1986 Plan.
 
     The 1986 Plan may be amended by the Board of Directors of Penril, provided
that stockholder approval will be necessary as required under Section 422 of the
Code or Rule 16b-3 of the regulations of the Exchange Act, and provided further
the no amendment may impair any rights of any holder of an Award previously
granted under the 1986 Plan without the holder's consent.
 
     The 1995 Long-Term Incentive Plan of Penril. On December 13, 1995, Penril
adopted the 1995 Long-Term Incentive Plan of Penril (the "1995 Plan"). The 1995
Plan is intended to encourage officers and other key employees of Penril and its
subsidiaries to acquire or increase their ownership of Penril Stock.
 
     The 1995 Plan authorizes the grant to officers and key employees of awards
("Awards") consisting of "incentive stock options," as that term is defined
under the provisions of Section 422 of the Code, non-
 
                                       36
<PAGE>   38
 
qualified stock options and restricted stock awards. There are 930,000 shares of
Penril Stock available for granting Awards under the 1995 Plan. The Penril
Committee administers the 1995 Plan and has sole discretion to determine those
employees to whom Awards will be granted, the number of Awards granted, the
provisions applicable to each Award and the time periods during which Awards may
be exercisable.
 
     The Penril Committee may grant incentive stock options, non-qualified stock
options, or a combination of the two. The exercise price of each incentive stock
option may not be less than the fair market value of Penril Stock at the date of
grant. Under the 1995 Plan, fair market value is generally the closing price of
Penril Stock on the last business day prior to the date on which the value is to
be determined. Unless the Penril Committee determines otherwise, the option
price per share of any non-qualified stock option will be the fair market value
of the shares of Penril Stock on the date the option is granted. The exercise
price of each incentive stock option granted to any stockholder possessing more
than 10% of the combined voting power of all classes of capital stock of Penril,
or, if applicable, a parent or subsidiary of Penril, on the date of grant must
not be less than 110% of the fair market value on that date, and no such option
may be exercisable more than five years after the date of grant.
 
     Options granted will be exercisable for a term of not more than ten years
from the date of grant. In addition, no employee may be granted an incentive
stock option to the extent the aggregate fair market value, as of the date of
grant, of the stock with respect to which incentive stock options are first
exercisable by such employee during any calendar year, exceeds $100,000.
 
     Restricted stock awards are rights granted by the Penril Committee to
receive shares of Company Stock subject to forfeiture and other restrictions
determined by the Penril Committee. Until the restrictions with respect to any
restricted stock award lapse, the shares will be held by Penril and may not be
sold or otherwise transferred by the employee. Except as otherwise determined by
the Penril Committee, until the restrictions lapse, the shares will be forfeited
if the employee's employment is terminated for any reason other than death,
disability or retirement on or after the employee's attainment of 65 years of
age. Except as otherwise determined by the Penril Committee, all restrictions
will lapse upon the earliest of the death, disability or retirement of the
recipient employee on or after the employee's attainment of 65 years of age.
Unless the Penril Committee determines otherwise, 30% of the shares subject to a
restricted stock award will vest on the first anniversary of the date of grant,
60% on the second anniversary and 100% on the third anniversary of the grant.
 
     Awards granted under the 1995 Plan will be subject to adjustment upon a
recapitalization, stock split, stock dividend, merger, reorganization,
liquidation, extraordinary dividend, or other similar event affecting Penril
Stock. An Award will not be transferable, other than by will or the laws of
descent and distribution or, in certain circumstances, pursuant to a qualified
domestic relations order, and an Award may be exercised, during the lifetime of
the holder of the Award, only by the holder, or the holder's personal
representative in the event of disability.
 
     In the case of a "change in control" of Penril, 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 they previously have not been exercised, without regard to any
vesting limitations. On July 2, 1996 the Penril Committee took action which
caused all of the outstanding Penril options held by directors and executive
officers of Penril to vest.
 
     Penril, in its sole discretion, may establish procedures, subject to
certain restrictions, whereby an option holder, subject to the requirements of
Rule 16b-3, Regulation T, and certain other laws, may exercise an option or a
portion thereof without making a direct payment of the option price to Penril,
without regard to any vesting limitations.
 
     The 1995 Plan will terminate on December 13, 2005, and Awards may not be
granted under the 1995 Plan after that date, although the terms of any Award may
be amended in accordance with the 1995 Plan at any date prior to the end of the
term of such Award. Any Awards outstanding at the time of termination of the
 
                                       37
<PAGE>   39
 
1995 Plan will continue in full force and effect according to the terms and
conditions of the Award and the 1995 Plan.
 
     The 1995 Plan may be amended by the Board of Directors of Penril, provided
that stockholder approval will be necessary as required under the Section 422 of
the Code or Rule 16b-3 of the regulations of the Exchange Act, and provided
further that no amendment may impair any rights of any holder of an Award
previously granted under the 1995 Plan without the holder's consent.
 
COMPANY BENEFIT PLANS
 
     The Company's 1996 Long-Term Incentive Plan. It is expected that the Board
of Directors of the Company will adopt the Company's 1996 Long-Term Incentive
Plan (the "Company Incentive Plan"), subject to approval by the Company's
stockholders. The Company Incentive Plan will be intended to encourage ownership
of Company Stock by officers and other key employees of the Company, to
encourage their continued employment with the Company and to provide them with
additional incentives to promote the success of the Company.
 
   
     The Company Incentive Plan will authorize the grant to officers and key
employees of options ("Options") consisting of "incentive stock options," as
that term is defined under the provisions of Section 422 of the Code and
non-qualified stock options. There will be 2,000,000 shares of Company Stock
available for granting Options under the Company Incentive Plan. The
Compensation Committee of the Board of Directors of the Company (the
"Committee") will administer the Company Incentive Plan and will have sole
discretion to determine those employees to whom Options will be granted, the
number of Options granted, the provisions applicable to each Option and the time
periods during which Options may be exercisable; provided, however, that no
employee may receive Options to acquire more than 500,000 shares of Company
Stock during any given year.
    
 
   
     The Committee may grant incentive stock options, non-qualified stock
options, or a combination of the two. The exercise price of each incentive stock
option may not be less than the fair market value of the Company Stock at the
date of grant. Under the Company Incentive Plan, fair market value generally
will be the closing price of the Company Stock on Nasdaq on the last business
day prior to the date on which the value is to be determined; provided, however,
with respect to options granted on or before the Distribution Date, fair market
value means the average of the daily closing price of the Company Stock for the
first ten consecutive trading days that Company Stock is traded on Nasdaq other
than on an "as issued" or "when issued" basis, calculated to the nearest cent,
as determined by the Company. Unless the Committee determines otherwise, the
option price per share of any non-qualified stock option will be the fair market
value of the shares of Company Stock on the date the option is granted. The
exercise price of each incentive stock option granted to any stockholder
possessing more than 10% of the combined voting power of all classes of capital
stock of the Company, or, if applicable, a parent or subsidiary of the Company,
on the date of grant must not be less than 110% of the fair market value on that
date, and no such option may be exercisable more than five years after the date
of grant.
    
 
   
     Options granted will be exercisable for a term of not more than ten years
from the grant. Unless the Committee determines otherwise, Options may be
exercised as to 30% of the shares subject to an Option at any time after the
first anniversary of the date of grant, as to 60% of the shares subject to an
Option at any time after the second anniversary of the date of grant and as to
all shares subject to an Option at any time after the third anniversary of the
date of grant. In addition, no employee may be granted an incentive stock option
to the extent the aggregate fair market value, as of the date of grant, of the
stock with respect to which incentive stock options are first exercisable by
such employee during any calendar year exceeds $100,000.
    
 
   
     Options granted under the Company Incentive Plan will be subject to
adjustment upon a recapitalization, stock split, stock dividend, merger,
reorganization, liquidation, extraordinary dividend or other similar event
affecting the Company Stock. An Option will not be transferable, other than by
will or the laws of descent and distribution or, in certain circumstances,
pursuant to a qualified domestic relations order, and an Option may be
exercised, during the lifetime of the holder of the Option, only by the holder,
or the holder's personal representative in the event of disability.
    
 
                                       38
<PAGE>   40
 
   
     In the case of a "change in control" of the Company, each Option granted
under the Company Incentive Plan will terminate 90 days after the occurrence of
such "change in control" and 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 they
previously have not been exercised.
    
 
   
     The Company Incentive Plan will terminate ten years after adoption and
Options will not be granted under the Company Incentive Plan after that date
although the terms of any Option may be amended in accordance with the Company
Incentive Plan at any date prior to the end of the term of such Option. Any
Options outstanding at the time of termination of the Company Incentive Plan
will continue in full force and effect according to the terms and conditions of
the Option and the Company Incentive Plan.
    
 
   
     The Company Incentive Plan may be amended by the Board of Directors of the
Company, provided that stockholder approval will be necessary as required under
Section 422 of the Code or Rule 16b-3 of the regulations of the Exchange Act,
and provided further that no amendment may impair any rights of any holder of an
Option previously granted under the Company Incentive Plan without the holder's
consent.
    
 
     The Company's 1996 Non-Employee Directors' Stock Option Plan.  It is
expected that the Board of Directors of the Company will adopt the 1996
Non-Employee Directors' Stock Option Plan (the "Directors' Plan").
 
   
     The Directors' Plan is intended to encourage non-employee directors of the
Company to acquire or increase their ownership of Company Stock on reasonable
terms, and to foster a strong incentive to put forth maximum effort for the
continued success and growth of the Company. The Directors' Plan provides for
the granting of non-qualified stock options to purchase 250,000 shares of
Company Stock to current and future non-employee directors of the Company. As of
the Distribution Date, the non-employee directors eligible to receive stock
options under the Directors' Plan will be Arthur Samberg, Barbara Perrier, John
Howard and Paul Schaller.
    
 
   
     Each of the directors identified above as being eligible to receive stock
options under the Directors' Plan will be granted an option on or immediately
prior to the Distribution Date to purchase 25,000 shares of Company Stock. Each
non-employee director who subsequently joins the Board of Directors will be
granted, on the first business day following the first day of his term, an
option to purchase 25,000 shares of Company Stock. On the fifth business day
after the Company's Annual Report on Form 10-K is filed with the Commission for
each fiscal year that the Directors' Plan is in effect, each person who is a
non-employee Director on such date will receive an additional option to purchase
5,000 shares of Company Stock. If the number of shares available for grant under
the Directors' Plan on a scheduled date of grant is insufficient to make all the
grants, then each eligible director will receive an option to purchase a pro
rata number of the available shares.
    
 
   
     The option price per share will be the fair market value of the shares of
Company Stock on the date of grant. Under the Directors' Plan, fair market value
is generally the closing price of the Company Stock on Nasdaq on the last
business day prior to the date on which the value is to be determined; provided,
however, that with respect to the initial option grants, fair market value means
the average of the daily closing price of the Company Stock for the first ten
consecutive trading days that Company Stock is traded on Nasdaq other than on an
"as issued" or "when issued" basis calculated to the nearest cent, as determined
by the Company.
    
 
   
     The options granted under the Directors' Plan will be exercisable for a
term of ten years from the date of grant, subject to earlier termination, and
may be exercised as follows: (a) any options granted as of the effective date of
the Directors' Plan or as of the first day of a Director's initial term on the
Board of Directors of the Company may be exercised as to 30% of the shares
subject to such option at any time after the first anniversary of the date of
grant, as to 60% of the shares subject to such option at any time after the
second anniversary of the date of grant, and as to all shares subject to such
option at any time after the third anniversary of the date of grant and (b) any
other options may be exercised at any time after the third anniversary of the
date of grant.

<PAGE>   41
 
   
     In the event that a director ceases to be a member of the Board of
Directors of the Company (other than by reason of death or disability), an
option may be exercised by the director (to the extent the director was entitled
to do so at the time he ceased to be a member of the Board of Directors of the
Company) at any time within seven months after he ceases to be a member of the
Board of Directors of the Company, but not beyond the term of the option. If the
director dies or becomes disabled while he is a member of the Board of Directors
of the Company or within seven months thereafter, an option may be exercised (to
the extent the director shall have been entitled to exercise the option as of
the date of his death or the termination of his directorship by reason of his
disability) by a legatee of the director under his will, or by him or his
personal representative or distributees, as the case may be, at any time within
12 months after his death or disability, but not beyond the term of the option.
The Directors' Plan will be administered by the Committee.
    
 
     Options granted under the Directors' Plan will be subject to adjustment
upon a recapitalization, stock split, stock dividend, merger, reorganization,
liquidation, extraordinary dividend or other similar event affecting the Company
Stock. Options will not be transferable other than by will or pursuant to the
laws of descent and distribution or pursuant to a qualified domestic relations
order, and will be exercisable during the lifetime of an option holder only by
such holder or his personal representative in the event of disability.
 
     Upon a "change in control" of the Company (as defined in the Directors'
Plan), each option granted under the Directors' Plan will terminate on the later
of (i) 90 days after the occurrence of the "change in control" and (ii) seven
months following the date of grant of each option, and an option holder will
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
they have not previously been exercised.
 
   
     The Directors' Plan will terminate on the tenth anniversity of the
Distribution Date and options may not be granted under the Directors' Plan after
that date, although the terms of any option may be amended in accordance with
the Directors' Plan at any date prior to the end of the term of that option. Any
options outstanding at the time of termination of the Directors' Plan will
continue in full force and effect according to the terms and conditions of the
option and the Directors' Plan.
    
 
     The Directors' Plan may be amended by the Board of Directors of the
Company, provided that stockholder approval will be necessary if required under
Rule 16b-3 of the General Rules and Regulations of the Exchange Act, and no
amendment may impair any of the rights of any holder of an option previously
granted under the Directors' Plan without the holder's consent.
 
     The principal terms of the option grants are fixed in the Directors' Plan.
Therefore, the Committee will have no discretion to select which directors
receive options, the number of shares of Company stock included in any grant, or
the exercise price of options.

                               SECURITY OWNERSHIP
 
   
     All of the outstanding Company Stock will be held by Penril until the
Distribution. The following table sets forth the projected beneficial ownership
of the Company Stock immediately following the Distribution by each director and
executive officer of the Company at that time and all directors and executive
officers of the Company at that time as a group, as well as by any person
projected to own beneficially more than 5% of the Company Stock, based upon such
person's reported ownership of Penril Stock in filings made with the Commission
pursuant to Sections 13(d) and 13(g) of the Exchange Act as of September 30,
1996. The information in this table was based in part on information supplied by
the named individuals. Various members of management of the Company have
indicated that they may purchase shares of Company Stock in the open market
after the Distribution Date.

    partnership ("International Partners"). (Pequot Partners Fund, L.P., Pequot
    Endowment Fund, L.P. and Pequot International Fund Inc. are collectively
    referred to as the "Funds"). Mr. Samberg is a General Partner and senior
    portfolio manager of each of the Funds. General Partners, Endowment Partners
    and International Partners (collectively, the "Partners") are to be the
    beneficial owners, as such term is used in Rule 13d-3 of the Exchange Act,
    of the shares of Common Stock to be owned by the Fund for which they act as

    group as such term is used in Section 13(d) (3) of the Exchange Act. Each of
    the Partners disclaims beneficial ownership of the Common Stock to be
    beneficially owned by the other partners. On September 22, 1995, the Funds
    purchased from Penril in a private placement an aggregate of 1,465,000

                          DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED CAPITAL STOCK
 
   
     The authorized capital stock of the Company consists of 30,000,000 shares
of Company Stock, and 3,000,000 shares of preferred stock, $.01 par value per
share ("Company Preferred Stock"). Immediately after the Distribution, it is
estimated that 11,993,000 shares of Company Stock will be issued and
outstanding.
    
 
COMPANY STOCK
 
     The holders of Company Stock are entitled to one vote for each share held
of record on all matters submitted to the vote of stockholders, including the
election of directors. The holders of Company Stock do not have cumulative
voting rights. Subject to any preferential rights held by holders of the Company
Preferred Stock, the holders of Company Stock are entitled to receive ratably
such dividends as may be declared from time to time by the Company's Board of
Directors out of funds legally available therefor. In the event of the
liquidation, dissolution or winding up of the Company, holders of Company Stock
will be entitled to share ratably in all assets remaining after payment of
liabilities and the liquidation preference of outstanding Company Preferred
Stock, if any. Holders of Company Stock do not have preemptive, conversion or
redemption rights. All the issued and outstanding shares of Company Stock are
duly authorized, validly issued, fully paid and nonassessable.
 
     No current public trading market for the Company Stock exists, although the
Company intends to list the Company Stock on Nasdaq. The extent of the market
for the Company Stock and the prices at which the Company Stock may trade cannot
be predicted. Until the Company Stock is distributed and an orderly market
develops, the trading price may be volatile.
 
   
     After the Distribution, the Company will be an independent, publicly-traded
company, owning, among other things, the Remote Access Business. The number and
identity of stockholders of the Company immediately after the Distribution
cannot currently be determined with certainty because it will be based on the
number and identity of stockholders of Penril on the Distribution Date. However,
based on the number of record stockholders and outstanding shares of Penril
Stock as of the close of business on September 30, 1996 and the distribution
ratio of one share of Company Stock for every one share of Penril Stock, the
Company expects to have approximately 921 holders of record of Company Stock and
approximately 11,993,000 shares of Company Stock issued and outstanding
immediately after the Distribution and no holders of record of Company Preferred
Stock or shares of Company Preferred Stock issued and outstanding immediately
after the Distribution. In addition, as provided for in the Company Incentive
Plan and the Directors' Plan, it is anticipated that the total number of shares
of Company Stock with respect to which options may be granted and restricted
stock may be awarded under the Company Incentive Plan and the Directors' Plan
will not exceed 2,250,000 shares, 250,000 of which would be allocated strictly
to the Directors' Plan, subject to adjustment (together with the exercise price
of options and the purchase price, if any, of restricted stock) to reflect any
change in the Company's outstanding shares of Company Stock by reason of stock
dividends, stock splits, recapitalizations, mergers, consolidations or other
similar events affecting the number or kind of outstanding shares. It is
believed that directors and executive officers of the Company will own, in the
aggregate, less than twenty-six percent (26%) of the outstanding shares of
Company Stock immediately after the Distribution. See "Security Ownership."
    
 
     The Company Stock distributed to Penril stockholders will be freely
transferable, except for shares received by any persons who may be deemed to be
"affiliates" of the Company under the Securities Act. Persons who may be deemed
to be affiliates of the Company after the Distribution generally include
individuals or entities that control, are controlled by, or are under common
control with the Company and may include certain officers and directors of the
Company as well as principal stockholders of the Company. Persons who are
affiliates of the Company will be permitted to sell their shares of Company
Stock only pursuant to an effective registration statement under the Securities
Act or an exemption from the registration requirements of the Securities Act,
such as the exemption provided by Section 4(1) of the Securities Act or Rule 144
thereunder. The Section 4(1) exemption allows the sale of unregistered shares by
a person who is not an issuer, an underwriter or a dealer. Rule 144 provides
persons who are not issuers with objective
 
                                       43
<PAGE>   45
 
   
standards for selling restricted securities and securities held by affiliates
without registration. The rule requires that (1) current public information be
available concerning the issuer; (2) restricted stock generally be held two
years or more; (3) volume limitations are placed on sales during any three-month
period; and (4) affiliates comply with certain manner of sale restrictions. The
amount of Company Common Stock which could be sold by a person (or persons whose
shares are aggregated) under Rule 144 during a three month period cannot exceed
the greater of (1) one percent of the shares of Company Common Stock outstanding
as shown by the most recent report or statement published by the Company, or (2)
the average weekly trading volume for the shares for a four-week period prior to
the date that notice of the sale is filed with the Commission.
    
 
     The transfer agent and registrar for the Company Stock is Continental Stock
Transfer & Trust Company.
 
PREFERRED STOCK
 
     The Board of Directors of the Company, without further approval or action
by the stockholders, is authorized to issue shares of Company Preferred Stock in
one or more series and to fix as to any such series the dividend rate,
redemption prices, preferences on liquidation or dissolution, sinking fund
terms, if any, conversion rights, voting rights and any other preference or
special rights and qualifications. Issuances of Company Preferred Stock may
adversely affect the rights of holders of Company Common Stock. Holders of
Company Preferred Stock might, for example, be entitled to preference in
distributions to be made to stockholders upon the liquidation, dissolution or
winding up of the Company. In addition, holders of Company Preferred Stock might
enjoy voting rights that limit, qualify or adversely affect the voting rights of
holders of Company Stock. Such rights of the holders of one or more series of
Company Preferred Stock might include the right to vote as a class with respect
to the election of directors, major corporate transactions or otherwise, or the
right to vote together with the holders of Company Stock with respect to any
such matter. The holders of Company Preferred Stock might be entitled to cast
multiple votes per share. The issuance of Company Preferred Stock could have the
effect of delaying, deferring, or preventing a change in control of the Company
without further action by the stockholders. The Company has no present plans to
issue any shares of Preferred Stock.
 
ANTITAKEOVER PROVISIONS OF THE COMPANY CERTIFICATE AND COMPANY BY-LAWS
 
     Penril, as sole stockholder of the Company, has approved a Company
Certificate and Company By-laws. Such Company Certificate and Company By-laws
(i) provide for a Classified Board of Directors of the Company from which
directors may only be removed by Stockholders for cause; (ii) generally provide
that only a majority of the Board of Directors of the Company shall have the
authority to fill vacancies on the Board of Directors; (iii) restrict the right
to amend certain provisions of the Company Certificate and Company By-laws; (iv)
restrict the right of stockholders to call special meetings; (v) establish an
advance notice procedure regarding the nomination of directors by stockholders
and stockholder proposals to be brought before an annual meeting; and (vi)
authorize the Company's Board of Directors to issue Company Preferred Stock
without further stockholder approval. These provisions are designed to encourage
any person who desires to take control of and/or acquire the Company to enter
into negotiations with the Board of Directors of the Company, thereby making
more difficult the acquisition of the Company by means of a tender offer, a
proxy contest or other non-negotiated means. In addition to encouraging any
person intending to attempt a takeover of the Company to negotiate with the
Board of Directors of the Company, these provisions also curtail such person's
use of a dominant equity interest to control any negotiations with the Board of
Directors of the Company. Under such circumstances, the Board of Directors of
the Company may be better able to make and implement reasoned business decisions
and protect the interests of all of the Company's stockholders. A copy of the
Company Certificate and Company By-laws are each filed as an exhibit to the
Registration Statement of which this Prospectus is a part.
 
     Classified Board of Directors.  The Company Certificate provides for the
Board of Directors of the Company to be divided into three classes serving
staggered terms so that directors' initial terms will expire at the 1997, 1998
or 1999 annual meeting of stockholders. Starting with the 1997 annual meeting of
the
 
                                       44
<PAGE>   46
 
Company's stockholders, one class of directors will be elected each year for a
three-year term. See "Management -- Directors and Executive Officers." The
classes will be as nearly equal in number as possible. The classification of
directors makes it more difficult for a significant stockholder to change the
composition of the Board of Directors of the Company in a relatively short
period of time and, accordingly, provides the Board of Directors of the Company
and stockholders time to review any nomination that a significant stockholder
may make and to pursue alternative courses of action which it believes are fair
to all the stockholders of the Company.
 
     Removal of and Filling Vacancies on the Board of Directors of the
Company.  The Company Certificate provides that, subject to any rights of the
holders of any class or series of the capital stock of the Company entitled to
vote generally in the election of directors, only a majority vote of the members
of the Board of Directors then in office, although less than a quorum, shall
have the authority to fill any vacancies on the Board of Directors of the
Company, including vacancies created by an increase in the authorized number of
directors. Moreover, because the Company Certificate provides for a classified
board, Delaware law provides that the stockholders may remove a member of the
Board of Directors of the Company only for cause and the Company Certificate
requires the affirmative vote of the holders of at least 80% of the voting power
of all the then-outstanding shares of the voting stock of the Company, voting
together as a single class, to remove a member of the Board of Directors. These
provisions relating to removal and filling of vacancies on the Board of
Directors of the Company preclude stockholders from enlarging the Board of
Directors of the Company or removing incumbent directors and filling vacancies
with their own nominees.
 
     Amendment of the Company Certificate and Company By-laws.  The Company
Certificate contains provisions requiring the affirmative vote of the holders of
at least 80% of the voting power of the Company Stock entitled to vote generally
in the election of directors to amend certain provisions of the Company
Certificate and Company By-laws (including certain of the provisions discussed
above). These provisions make it more difficult for stockholders to make changes
in the Company Certificate or Company By-laws, including changes designed to
facilitate the exercise of control over the Company.
 
     Special Meetings.  The Company By-laws provide that special meetings of
stockholders can be called only by the Chairman of the Board, the Vice Chairman
of the Board, the President or any Vice President, the Secretary or by the Board
of Directors of the Company. Stockholders are not permitted to call a special
meeting but may, upon a written request by stockholders owning a majority in
amount of the entire capital stock of the Company issued and outstanding and
entitled to vote, require that any of the foregoing call a special meeting of
stockholders. These provisions prohibit a significant stockholder from
authorizing stockholder action without a meeting at which all stockholders would
be entitled to participate.
 
     Nominations of Directors and Stockholder Proposals.  The Company By-laws
establish an advance notice procedure with regard to the nomination other than
by, or at the direction of, the Board of Directors of the Company of candidates
for election as directors (the "Nomination Procedure") and with regard to
stockholder proposals to be brought before an annual meeting of stockholders
(the "Business Procedure"). The Nomination Procedure provides that only persons
who are nominated by, or at the direction of, the Board of Directors of the
Company, or by a stockholder of the Company entitled to vote for the election of
directors who has given timely written notice to the Secretary of the Company
prior to the meeting at which directors are to be elected, are eligible for
election as directors of the Company. The Business Procedure provides that to be
properly brought before an annual meeting, business must be specified in the
notice of the annual meeting given by or at the direction of the Board of
Directors of the Company or brought before the meeting by, or at the direction
of, the Board of Directors of the Company or by a stockholder who has given
timely written notice to the Secretary of the Company of such stockholder's
intention to bring such business before such meeting. To be timely, notice for
nominations or stockholder proposals must be received by the Company not less
than 60 days prior to the annual meeting; provided, however, that in the event
that less than 70 days notice or prior public disclosure of the date of the
annual meeting is given or made to stockholders, notice by a stockholder, to be
timely, must be received no later than the close of business on the tenth day
following the day on which such notice of the date of the annual meeting was
mailed or such public disclosure was made, whichever first occurs. In addition
to the foregoing requirements, the proxy rules under the Exchange Act set
 
                                       45
<PAGE>   47
 
forth certain requirements, including stockholder eligibility, timing and
attendance requirements, which must be satisfied in order for a stockholder
proposal to be included in the Company's proxy statement and form of proxy.
These requirements under the Exchange Act may differ from those set forth under
the Nomination Procedure or the Business Procedure.
 
     Under the Nomination Procedure, notice to the Company from a stockholder
who proposes to nominate a person at an annual meeting for election as a
director must contain certain information about that person so nominated,
including age, business and residence addresses, principal occupation, the class
and number of shares of Company Stock beneficially owned, and such other
information as would be required to be included in a proxy statement soliciting
proxies for the election of the proposed nominee, and certain information about
the stockholder proposing to nominate that person. Under the Business Procedure,
notice relating to a stockholder proposal must contain certain information about
such proposal and about the stockholder who proposes to bring the proposal
before the meeting, including the class and number of shares of Company Stock
beneficially owned by such stockholder. If the officer of the Company presiding
at the meeting determines that a person was not nominated in accordance with the
Nomination Procedure, or that other business was not brought before the meeting
in accordance with the Business Procedure, such person is not eligible for
election as a director, or such business is not to be conducted as such meeting,
as the case may be.
 
     The purpose of the Nomination Procedure is, by requiring advance notice of
nomination by stockholders, to afford the Board of Directors of the Company a
meaningful opportunity to consider the qualifications of the proposed nominees
and, to the extent deemed necessary or desirable by the Board of Directors of
the Company, to inform stockholders about such qualifications. The purpose of
the Business Procedure is, by requiring advance notice of stockholder proposals,
to provide a more orderly procedure for conducting annual meetings of
stockholders and, to the extent deemed necessary or desirable by the Board of
Directors of the Company, to provide the Board of Directors of the Company with
a meaningful opportunity to inform stockholders, prior to such meetings, of any
proposal to be introduced at such meetings, together with any recommendation as
to the Board of Directors of the Company's position or belief as to action to be
taken with respect to such proposal, so as to enable stockholders better to
determine whether they desire to attend such meeting or grant a proxy to the
Board of Directors of the Company as to the disposition of any such proposal.
Although the Company By-laws do not give the Board of Directors of the Company
any power to approve or disapprove stockholder nominations for the election of
directors or any other proposal submitted by stockholders, the Company By-laws
may have the effect of precluding a nomination for the election of directors or
precluding the conducting of business at a particular stockholder meeting if the
proper procedures are not followed, and may discourage or deter a third party
from conducting a solicitation of proxies to elect its own slate of directors or
otherwise attempting to obtain control of the Company, even if the conduct of
such solicitation or such attempt might be beneficial to the Company and its
stockholders.
 
     Issuance of Company Preferred Stock.  The Company Certificate authorizes
the Board of Directors of the Company to issue Company Preferred Stock, without
further stockholder approval, which could have dividend, redemption,
liquidation, conversion, voting or other rights that could adversely affect the
voting power and other rights of holders of Company Stock. The ability of the
Board of Directors of the Company to issue Company Preferred Stock could have
the effect of delaying, deferring, or preventing a change in control of the
Company without further action by the stockholders.
 
                      COMPARISON OF RIGHTS OF STOCKHOLDERS
                           OF THE COMPANY AND PENRIL
 
     Following the Distribution, holders of Penril Stock will become holders of
Company Stock and the rights of such holders will be governed by the Company
Certificate and the Company By-laws. The rights of Company stockholders differ
in certain respects from the rights of Penril stockholders. Certain of the
differences are summarized below. This summary is qualified in its entirety by
reference to the full text of such documents.
 
                                       46
<PAGE>   48
 
BUSINESS COMBINATIONS
 
     Generally, under the DGCL, the approval by the affirmative vote of the
holders of a majority of the outstanding stock (or, if the certificate of
incorporation provides for more or less than one vote per share, a majority of
the votes of the outstanding stock) of a corporation entitled to vote on the
matter is required for a merger or consolidation or sale, lease or exchange of
all or substantially all of the corporation's assets to be consummated.
 
     The Company Certificate does not contain provisions regarding business
combinations and does not impose requirements in addition to or different from
those imposed by the DGCL.
 
     Penril's Amended and Restated Certificate of Incorporation (the "Penril
Certificate") provides that, subject to certain exceptions, the affirmative vote
of the holders of at least 80% of the voting power of all the then-outstanding
shares of capital stock of Penril entitled to vote generally in the election of
directors is required to approve every "Business Combination" (defined to
include mergers, consolidations, sales of assets of Penril having a fair market
value of $1,000,000 or more, issuances or transfers by Penril of any securities
of Penril having a fair market value of $1,000,000 or more, and certain other
transactions) between Penril and any "Interested Stockholder" (generally defined
to mean any beneficial owner of more than 10% of the voting power of the
outstanding Penril voting stock). Such 80% vote is not required if the Business
Combination is approved by a majority of the Continuing Directors (generally
defined to mean the directors who were members of the Penril Board on December
13, 1983 or a person designated as a Continuing Director by a majority of the
Continuing Directors) or if the Business Combination satisfies certain price and
procedural conditions. With respect to business combinations other than with
Interested Stockholders, the Penril Certificate does not impose requirements in
addition to or different from those imposed by the DGCL.
 
AMENDMENTS TO CHARTERS
 
     Under the DGCL, unless otherwise provided in the certificate of
incorporation, a proposed amendment to the certificate of incorporation requires
an affirmative vote of a majority of the outstanding stock entitled to vote
thereon. If any such amendment would adversely affect the rights of any holders
of shares of a class or series of stock, the vote of the holders of a majority
of all outstanding shares of the class or series, voting as a class, is also
necessary to authorize such amendment. The Company Certificate provides that no
amendment to the Company Certificate shall amend, alter, change or repeal the
super majority voting provisions relating to the division of the Board of
Directors of the Company into classes; the number and removal of members of the
Board of Directors of the Company; term of office of members of the Board of
Directors of the Company; and the filling of vacancies on the Board of Directors
of the Company unless the amendment, alteration, change or repeal shall have
received the affirmative vote of the holders of at least 80% of the outstanding
shares of capital stock entitled to vote thereon. The Company Certificate
otherwise comports with the DGCL.
 
   
     The Penril Certificate provides that no amendment to the Penril Certificate
shall amend, alter, change or repeal any of the supermajority voting provisions
relating to business combinations; division into classes, number, removal of
members, term of office and the filling of vacancies on the Penril Board of
Directors; and Stockholder action at Stockholder meetings unless the amendment
effecting such amendment, alteration, change or repeal shall have received the
affirmative vote of the holders of at least 80% of the outstanding shares of
capital stock entitled to vote thereon. The Penril Certificate otherwise
comports with the DGCL.
    
 
AMENDMENTS TO BY-LAWS
 
     Under the DGCL, the power to adopt, alter and repeal the by-laws is vested
in the stockholders, except to the extent that the certificate of incorporation
vest it in the board of directors. The Company By-laws provide that the Company
By-laws, or any one of them, may be supplemented, amended or repealed by the
Board of Directors, or by the vote of a majority in interest of the stockholders
represented and entitled to vote thereon at any meeting at which a quorum is
present; provided, however, that the affirmative vote of the holders of at least
80% of the voting power of the then-outstanding shares of the Company voting
stock, voting together as a single class, is required to amend, alter or repeal
the sections of the Company By-Laws which have the same effect as those
provisions of the Company Certificate governing (i) division of the Company
Board of
 
                                       47
<PAGE>   49
 
Directors into three classes serving staggered three year terms; (ii) the number
of directors; (iii) term of office of directors; (iv) removal of directors and
(v) the filling of vacancies on the Board of Directors.
 
     The Penril By-laws provide that the Penril By-laws, or any of them, may be
supplemented, amended or repealed by the Penril Board of Directors, or by the
vote of a majority in interest of the stockholders represented and entitled to
vote thereon at any meeting at which a quorum is present; provided, however,
that the affirmative vote of the holders of at least 80% of the voting power of
all the then-outstanding shares of the Penril voting stock, voting together as a
single class, is required to amend, alter or repeal the sections of the Penril
By-laws governing (i) action of stockholders without a meeting; (ii) the number
of directors; (iii) term of office of directors; (iv) quorum and voting of
directors or (v) amendment of the Penril By-laws.
 
REDEMPTION OF CAPITAL STOCK
 
     Under the DGCL, subject to certain limitations, a corporation's stock may
be made subject to redemption by the corporation at its option, at the option of
the holders of such stock or upon the happening of a specified event. The DGCL
prohibits the purchase or redemption of stock when the capital of a corporation
is or would become impaired; but shares entitled to dividend or liquidation
preference may be purchased or redeemed out of capital if such shares are
retired and capital is reduced in accordance with legal requirements. The
Company Certificate does not contain any provisions relating to the right to
redeem outstanding shares of capital stock. The Penril Certificate grants the
Penril Board of Directors the authority to adopt amendments to the Penril
Certificate to provide for redemption of shares of capital stock of Penril, but
the Penril Certificate does not contain any provisions governing the right to
redeem outstanding shares of capital stock.
 
STOCKHOLDER ACTION
 
     Under the DGCL, unless otherwise provided in the certificate of
incorporation, any action required or permitted to be taken at a meeting of
stockholders may be taken without a meeting, without prior notice and without a
vote, if a written consent or consents setting forth the action taken is signed
by the holders of outstanding stock having not less than the minimum number of
votes that would be necessary to authorize or take such action at a meeting at
which all shares entitled to vote upon such action were present and voted. The
Company Certificate and the Company By-laws provide that all elections and
questions put to stockholders shall be decided by the vote of a majority in
interest of the stockholders present in person or represented by proxy and
entitled to vote at the meeting, except as otherwise permitted or required by
the DGCL, the Company Certificate or the Company By-Laws. The Penril Certificate
provides that any action required or permitted to be taken by stockholders must
be effected at an annual meeting of stockholders and may not be effected by any
consent in writing by such stockholders.
 
SPECIAL STOCKHOLDER MEETINGS
 
     The DGCL provides that a special meeting of stockholders may be called by
the board of directors or by such person or persons as may be authorized by the
certificate of incorporation or by the by-laws. The Company By-laws provide that
special meetings may be called by the Chairman of the Board, the Vice Chairman
of the Board, the President, any Vice President or by the Board of Directors and
shall be called by any of the foregoing at the request in writing of
stockholders owning a majority in amount of the entire capital stock of the
Company issued and outstanding and entitled to vote. The Penril Certificate and
By-laws provide that meetings of stockholders may be called only by the Penril
Board of Directors pursuant to a resolution adopted by a majority of the total
number of authorized directors.
 
NUMBER AND ELECTION OF DIRECTORS
 
     The DGCL permits the certificate of incorporation or the by-laws of a
corporation to contain provisions governing the number and terms of directors.
However, if the certificate of incorporation contains provisions fixing the
number of directors, such number may not be changed without amending the
certificate of incorporation. The Company Certificate provides that the number
of directors shall be fixed from time to time pursuant to a resolution adopted
by a majority of the entire Board of Directors. The Penril Certificate provides
 
                                       48
<PAGE>   50
 
that the number of directors shall be fixed from time to time exclusively by the
Penril Board of Directors pursuant to a resolution adopted by a majority of the
total number of authorized directors (whether or not there exist any vacancies
in previously authorized directorships at the time any such resolution is
presented for adoption).
 
     The DGCL permits the certificate of incorporation of a corporation or the
by-laws to provide that directors be divided into one, two or three classes. The
term of office of one class of directors shall expire each year with the terms
of office of no two classes expiring the same year. The Board of Directors
consists of 5 individuals divided into three classes with each director serving
a three year term (after the initial term). The Penril Certificate divides
Penril's Board of Directors into three classes with each director serving a
three year term.
 
ANTITAKEOVER PROVISIONS
 
     The Company Certificate requires the affirmative vote of the holders of at
least 80% of the votes which all stockholders would be entitled to cast at any
annual election of directors or class of directors to amend or repeal, or to
adopt any provision inconsistent with certain provisions of the Company
Certificate. The provisions of the Company Certificate subject to the 80% vote
requirement include the provisions which divide the Board of Directors into
three classes serving staggered three year terms, establish the term of office
of directors and the standards for removal of directors and the filling of
vacancies on the Board of Directors. The Company Certificate also authorizes the
Board of Directors to issue Company Preferred Stock, without further stockholder
approval, which could have dividend, redemption, liquidation, conversion, voting
or other rights that could adversely affect the voting power or other rights of
holders of Company Stock. In addition, the Company By-laws contain certain
antitakeover provisions which establish an advance notice procedure regarding
the nomination of directors by stockholders and stockholder proposals to be
brought before an annual meeting and provisions which restrict the right of
stockholders to call special meetings.
 
     The Penril Certificate requires the affirmative vote of the holders of at
least 80% of the votes which all stockholders would be entitled to cast at any
annual election of directors or class of directors to amend or repeal, or to
adopt any provision inconsistent with certain provisions of Penril's Certificate
of Incorporation. The provisions of the Penril Certificate subject to the 80%
vote requirement include those provisions which (i) divide the Penril Board of
Directors into three classes serving staggered three year terms and establish
the standards for the number, term of office, removal of directors and the
filling of vacancies on the Penril Board of Directors; (ii) prohibit
stockholders from acting by written consent in lieu of a meeting; (iii) provide
that special meetings of stockholders may be called only by the Penril Board of
Directors pursuant to a resolution adopted by a majority of the total number of
authorized directors; and (iv) require an 80% vote to approve "Business
Combinations" with "Interested Directors".
 
                        LIABILITY AND INDEMNIFICATION OF
                     OFFICERS AND DIRECTORS OF THE COMPANY
 
GENERAL
 
     Officers and directors of the Company will be covered by certain provisions
of the DGCL, the Company Certificate, certain indemnification agreements with
the Company and insurance policies which serve to limit and/or indemnify them
against certain liabilities which they may incur in such capacities. These
various provisions and policies are described below.
 
ELIMINATION OF LIABILITY IN CERTAIN CIRCUMSTANCES
 
     Under the DGCL, corporations are permitted to limit or eliminate the
personal liability of directors to corporations and their stockholders for
monetary damages for, among other things, breach of directors' fiduciary duty of
care. The duty of care requires that, when acting on behalf of the corporation,
directors must exercise an informed business judgment based on all material
information reasonably available to them. Absent the limitations now authorized
by such legislation, directors are accountable to corporations and their
 
                                       49
<PAGE>   51
 
stockholders for monetary damages for conduct constituting negligence or gross
negligence in the exercise of their duty of care. Although the statute does not
change directors' duty of care, it enables corporations to limit available
relief to equitable remedies such as injunction or recision. The Company
Certificate limits the liability of directors to the Company or its stockholders
to the fullest extent permitted by the DGCL. Specifically, no director of the
Company can be held personally liable for monetary damages for breach of such
director's fiduciary duty as a director, except for liability (i) for any breach
of the director's duty of loyalty to the Company or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) for unlawful payments of dividends or unlawful
stock repurchases or redemptions as provided in Section 174 of the DGCL or (iv)
for any transaction from which the director derived an improper personal
benefit.
 
INDEMNIFICATION AND INSURANCE
 
     Under the DGCL, the Company has the power, under specified circumstances
generally requiring the director or officer to act in good faith and in a manner
he reasonably believes to be in or not opposed to the Company's best interests,
to indemnify its directors and officers in connection with actions, suits or
proceedings brought against them by a third party or in the name of the Company,
by reason of the fact that they were or are such directors or officers, against
expenses, judgments, fines and amounts paid in settlement in connection with any
such action, suit or proceeding.
 
     The Company Certificate provides that the Company shall indemnify the
directors and officers of the Company to the fullest extent permitted by
Delaware law.
 
     Specifically, the Company Certificate provides that the Company shall
indemnify any person who is or was a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the Company), by reason of the fact that he (i) is or was a
director or officer of the Company, or (ii) is or was a director or officer of
the Company and is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Company and, with respect to any criminal action or proceeding,
had no reasonable cause to believe his conduct was unlawful. The termination of
any action, suit or proceeding by judgment, order, settlement, conviction or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the Company
or, with respect to any criminal action or proceeding, had reasonable cause to
believe that his conduct was unlawful.
 
     The Company Certificate provides that the Company shall indemnify any
person who is or was a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
Company to procure a judgment in its favor by reason of the fact that he is or
was a director or officer of the Company or is or was a director or officer of
the Company and is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection with the
defense or settlement of such action or suit if he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company; except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Company unless and only to the extent that the Court of Chancery
of the State of Delaware or the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which the Court of Chancery
of the State of Delaware or such other court shall deem proper.
 
     The Company Certificate provides that any indemnification under the
provisions described in the two paragraphs set forth above of a director,
officer, former director or former officer (unless ordered by a court)
 
                                       50
<PAGE>   52
 
shall be made by the Company only as authorized in the specific case upon a
determination that indemnification of the director or officer is proper in the
circumstances because he has met the applicable standard of conduct set forth in
the above two paragraphs. Such determination shall be made (i) by the Board of
Directors of the Company by a majority vote consisting of directors who were not
parties to such action, suit or proceeding, even though less than a quorum, or
(ii) if there are no such directors or if such directors so direct, by
independent legal counsel in a written opinion or (iii) by the stockholders of
the Company.
 
     The Company Certificate also provides, only as authorized in the sole
discretion of the Company, for indemnification of any employee, agent, former
employee or former agent of the Company who is or was a party or is threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding or in connection with the defense or settlement of
such action, suit or proceeding to the same extent as set forth in the first two
paragraphs of this section with respect to officers and directors of the
Company. The authorization of the Company to so indemnify such employees and/or
agents shall be made (i) by a majority vote of the directors who are not parties
to such action, suit or proceeding, even though less than a quorum, or (ii) if
there are no such directors, or if such directors so direct, by independent
legal counsel in a written opinion or (iii) by the stockholders.
 
     The Company Certificate provides that to the extent that a director or
officer or employee or agent of the Company has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to above, or in
defense of any claim, issue or matter therein, the Company shall indemnify him
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection therewith, without the necessity of authorization in the
specific case.
 
     The Company Certificate further provides that expenses incurred by a
director or officer in defending or investigating a threatened or pending
action, suit or proceeding may be paid by the Company in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of the director or officer to repay such amount if it shall
ultimately be determined that he is not entitled to be indemnified by the
Company as authorized in the Company Certificate. Such indemnification and
expenses incurred by other employees and agents may be so paid upon such terms
and conditions, if any, as the Board of Directors of the Company deems
appropriate.
 
     The Company Certificate provides that the indemnification and advancement
of expenses provided by, or granted pursuant to, the Company Certificate is not
deemed exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any by-law, agreement, vote of
stockholders or disinterested directors or pursuant to the direction of any
court of competent jurisdiction or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office. The
indemnification provided in the Company Certificate shall not be deemed to
preclude the indemnification of, and advancement of expenses to, any person who
is not specified in the Company Certificate, but whom the Company has the power
and obligation to indemnify under the provisions of the DGCL or otherwise.
 
     The Company intends to purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the Company, or
is or was a director, officer, employee or agent of the Company serving at the
request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise against any liability asserted against him or incurred by him in any
such capacity, or arising out of his status as such, whether or not the Company
would have the power or the obligation to indemnify him against such liability
under the Company Certificate.
 
     The Company will enter into indemnification agreements with each of the
Company's directors and officers. The indemnification agreements require, among
other things, the Company to indemnify the directors and officers to the fullest
extent permitted by law, and to advance to such directors and officers all
related expenses, subject to reimbursement if it is subsequently determined that
indemnification is not permitted. The indemnification agreements will require
that the Company also indemnify and advance all expenses incurred
 
                                       51
<PAGE>   53
 
by such directors and officers seeking to enforce their rights under the
indemnification agreements, and cover directors and officers under the Company's
directors' and officers' liability insurance. Although such indemnification
agreements will offer substantially the same scope of coverage afforded by
provisions in the Company Certificate, they provide greater assurance to
directors and officers that indemnification will be available because an
indemnification agreement, as a contract, cannot be modified unilaterally in the
future by the Board of Directors of the Company or by the stockholders to
eliminate the rights provided therein.
 
                              CERTAIN TRANSACTIONS
 
     On or prior to the Distribution Date, the Company and Penril will enter
into certain agreements, described below, which will govern their ongoing
relationships. These agreements were structured and negotiated while the Company
was owned by Penril and consequently are not the result of arms-length
negotiations between independent parties. Nonetheless, the Company and Penril
believe that the terms are fair to the parties and contain terms which are
generally comparable to those which would result from arms-length negotiations.
In each case, the terms of these agreements have been reviewed by individuals
who will be included at a senior management level of the Company.
 
     The agreements summarized below are filed as exhibits to the Registration
Statement. The following descriptions do not purport to be complete and are
qualified in their entirety by reference to the agreements as filed.
 
DISTRIBUTION AGREEMENT
 
   
     Prior to the Merger, Penril and the Company will enter into a Distribution
Agreement pursuant to which Penril will, among other things, (a) transfer to the
Company as a capital contribution all of Penril's right, title and interest in
the Remote Access Business and all of the other assets of Penril unrelated to
the modem business and (b) agree to make certain change of control payments in
the aggregate amount of $1,262,500 to three Penril officers prior to or at the
Effective Time; and the Company will (a) assume, pay, perform and discharge
substantially all of the liabilities of Penril other than (i) liabilities
relating to the modem business and (ii) the bank debt of Penril (which may not
exceed $4,000,000 at the Effective Time); and (b) indemnify Penril for any and
all liabilities, costs or expenses for the 401(k) Plan. At the time of the
capital contributions, Penril will own all of the Company's outstanding stock.
    
 
DEVELOPMENT AND LICENSE AGREEMENT
 
     On June 16, 1996, Penril and Bay entered into a Development and License
Agreement on behalf of the Company whereby Bay licensed to Penril, on behalf of
the Company, certain intellectual property, software and technical know-how
relating to certain 24-port Digital Modem Cards. The agreement contemplates that
Bay will develop a 24-port Digital Modem Card for the Company, train the
Company's personnel in the underlying technology, and provide technical
assistance where necessary to permit the Company to market this digital
technology. Penril will assign all of its rights under this Development and
License Agreement to the Company.
 
TECHNOLOGY LICENSE AGREEMENT
 
     In connection with the Transfer, Penril and the Company will enter into a
Technology License Agreement whereby Penril will license to the Company certain
intellectual property, software and technical know-how, including those relating
to a patent jointly owned by Penril and the University of Maryland. The
Technology License Agreement will also obligate Penril to use its best efforts
to obtain for the Company all rights obtained by Penril pursuant to cross
licensing agreements involving such jointly owned patent.

SUBLEASE AGREEMENT
 
   
     The Company will conduct most of its operations from its corporate
headquarters located in Gaithersburg, Maryland. The Company will sublease this
facility from Penril (the "Sublease"). Penril leases this property pursuant to a
lease with Real Estate Income Partners III (the "Overlease") dated March 31,
1989 as amended pursuant to a Letter Agreement dated May 14, 1990. The Overlease
provides for the rental of approximately 54,874 square feet of office space at a
current monthly payment for rent and additional charges of approximately
$66,219. The Overlease expires on September 30, 1999; however, Penril has one
option to extend the term of the Overlease for a period of 119 months.
    
 
   
     The Sublease will provide for the rental by the Company of the entire

INDEPENDENT AUDITORS' REPORT
 
   
Board of Directors and Stockholders
    
Penril DataComm Networks, Inc.
Gaithersburg, Maryland
 
   
We have audited the accompanying consolidated balance sheets of Penril DataComm
Networks, Inc. and subsidiaries as of July 31, 1996 and 1995, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended July 31, 1996. These financial
statements are the responsibility of Penril'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 Penril DataComm Networks, Inc. and
subsidiaries as of July 31, 1996 and 1995, and the results of their operations
and their cash flows for each of the three years in the period ended July 31,
1996 in conformity with generally accepted accounting principles.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
     PRINCIPLES OF CONSOLIDATION:  The consolidated financial statements include
the accounts of Penril and its subsidiaries, all of which are wholly owned. All
significant intercompany accounts and transactions have been eliminated.
    
 
   
     CASH AND CASH EQUIVALENTS:  Penril considers cash on hand, deposits in
banks, and highly liquid investments with an original maturity of three months
or less as cash and cash equivalents.
    
 
   
     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. Long-term debt is carried at
amounts approximating fair values based on current rates offered to Penril 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.

     PROPERTY, EQUIPMENT AND DEPRECIATION:  Additions to property and equipment
are recorded at cost. Penril provides depreciation for financial reporting
purposes using primarily the straight-line method over the estimated useful
lives of the assets which range from 3 to 10 years. Leasehold improvements are
amortized over the term of the related lease or their estimated useful lives,
whichever is shorter (in thousands).

     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 fulfillment of 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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     EXCESS OF COST OVER FAIR VALUE OF NET ASSETS ACQUIRED: During fiscal 1996,
Penril 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 Penril 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, Penril decided to restructure
and refocus its remaining businesses. Due to these events, Penril 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. This charge was the remaining balance in the
account "Excess of Costs over Fair Value of Net Assets Acquired" (See Note 2).

     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 fiscal 1996 and 1995 are
calculated based on the weighted average shares of common stock outstanding.
Earnings per share for fiscal 1994 year are calculated using the modified
treasury stock method, which limits the assumed purchase of treasury shares to
20% of the outstanding shares of common stock. Any remaining proceeds are
assumed first to retire debt, with any remaining proceeds invested in commercial
paper. The difference between fully diluted and primary earnings per share was
not significant in any year.
    
 
   
     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 and any other costs of development are expensed as incurred except
those costs applicable to third party contracts.
    
 
   
     NEW ACCOUNTING PRONOUNCEMENTS:  During fiscal 1996, Statement of Financial
Accounting Standard No. 123 ("SFAS 123"), "Accounting for Stock-Based
Compensation," which establishes a fair value based method for stock-based
compensation plans, was issued. SFAS 123 includes both recognition and
measurement provisions and disclosure requirements for stock-based compensation.
The Company has elected not to adopt the recognition and measurement provisions
of SFAS 123. The effect of adopting this statement in fiscal 1997 is not deemed
to be material.
    
 
   
     RECLASSIFICATIONS:  Certain reclassifications have been made to prior
period consolidated financial statements to conform to the July 31, 1996
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 transmis-

sion markets. As a result of this plan Penril recorded a charge of $9,718,000 in
the fourth quarter of fiscal 1996. This charge was for the following costs.
    
 
   
     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.
    
 
   
     b. A charge of $2,339,000 was taken for the write-off of inventory and
fixed assets related to the data transmission business.
    
 
   
     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, which will be vacated under the restructuring plan.
    
 
   
     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 has
no realizable value under the restructuring plan.
    
 
   
     e. A charge of $436,000 was taken for severance costs associated with
employees terminated in connection with the restructuring plan. No such costs
were paid as of July 31, 1996.
    
 
   
3.  DISCONTINUED OPERATIONS
    
 
   
     As part of Penril's decision to restructure its business, the Board of
Directors of Penril decided to sell Electro-Metrics, Inc. ("EMI"), a wholly
owned subsidiary which manufactures test equipment and systems for analysis of
electromagnetic interference and communications security including applications
in satellite communications. As a result of this decision, previously reported
financial statements have been restated to reflect EMI as a discontinued
operation.
    
 
   
     During fiscal 1995, the Board of Directors of Penril decided to sell
Technipower, a wholly-owned subsidiary manufacturing uninterruptible power
supplies and power regulating equipment. The divestiture of Technipower is
expected to be completed in fiscal 1997 for $4,300,000. The following table sets
forth the selected financial data of both Discontinued Operations (in
thousands):

4.  ACQUISITIONS
    
 
   
     On May 6, 1993, Penril acquired all of the outstanding stock of Datability,
Inc. ("Datability"). The acquisition was accounted for by the purchase method,
and accordingly, the results of operations of Datability are included in the
Consolidated Statements of Operations from the date of acquisition. Datability
has been consolidated with Penril's data communications operations located in
Gaithersburg, Maryland.
    
 
   
     The acquisition was accomplished through the issuance of 1,050,000 shares
of Penril's common stock ("Common Stock"). The purchase price totaled $4,980,000
including acquisition costs of $386,000. At the acquisition date, the purchase
price exceeded the fair value of net assets acquired by $8,169,000. Under terms
of the agreement, the final purchase price was dependent upon the valuation of
the net assets acquired. During fiscal 1994, a valuation adjustment of $829,000
resulted in 124,388 shares of the Common Stock being returned to Penril thereby
reducing the excess of cost over the fair value of net assets acquired. During
the fourth quarter of fiscal 1996, Penril expensed the remaining portion of
excess of cost over the fair value of net assets acquired.
    
 
   
5.  FINANCING
    
 
   
     BANK FINANCING: On March 15, 1996 Penril amended the credit agreement with
its principal bank. The new agreement provides for a maximum working capital
facility of $5,500,000 with borrowings based on qualified accounts receivable
and secured by substantially all Penril's assets. Interest accrues at the bank's
prime rate plus 2% with a commitment fee of 3/8% assessed on the unused portion
of the facility. In the event the facility is canceled prior to its expiration,
there is a fee due the bank equal to 3% of the total facility. The agreement
expires March 31, 1997. As of July 31, 1996, Penril had $5,412,000 available of
which Penril had utilized $4,000,000 for working capital loans and $90,000 for a
letter of credit. On June 16, 1996, Penril entered into a Plan and Agreement of
Merger, as amended on August 5, 1996 (the "Merger Agreement") with Bay Networks,
Inc. ("Bay") and a subsidiary of Bay. As part of the Merger Agreement with Bay,
outstanding bank debt up to $4,000,000 remains with Penril after the Transfer.
Average monthly borrowings and weighted average interest rate for the three
years ended July 31, 1996 are as follows:

     As of March 7, 1996, Penril had repaid all outstanding term debt with its
principal bank.
    
 
   
     SUBORDINATED DEBT:  In April 1995, as part of the bank financing
arrangements, Penril was permitted to make principal payments on the
subordinated debt only after the bank term loans had been reduced by $3,000,000.
This reduction was accomplished by December 1995 at which time Penril made a
subordinated debt principal payment of $174,000 as required by the amended
subordinated debt agreement. The remaining outstanding balance of $805,000 was
repaid in May 1996.

7.  COMMITMENTS AND CONTINGENCIES
    
 
   
PENDING TRANSACTION
    
 
   
     Under the terms of the Merger Agreement, Penril will transfer (the
"Transfer") all of its remote access products business and any other assets
unrelated to its modem business to a newly formed subsidiary, Access Beyond,
Inc. ("Access Beyond") and then distribute all of the shares of Access Beyond
common stock to Penril's stockholders in a spin-off transaction (the
"Spin-off"). Following the Spin-off, the subsidiary of Bay will merge with and
into Penril, whose primary remaining operations will consist of its modem
business, with Penril becoming a wholly owned subsidiary of Bay.
    
 
   
     Pursuant to the Spin-off and merger, stockholders of Penril, as of the
appropriate record dates, will receive one share of Access Beyond common stock
for every share of Penril common stock held, plus $10 in Bay common stock. The
dollar value of Bay shares to be paid is fixed according to an exchange value
determined by averaging the closing prices of Bay common stock over a specific
period prior to consummation of the merger with Bay. In addition to the assets
and liabilities related to the modem business, Bay will assume the outstanding
bank debt of Penril up to $4,000,000. All cash of Penril on the date of the
closing of the transactions will be transferred to Access Beyond.
    
 
   
     The transactions are subject to regulatory and Penril stockholders'
approval and certain conditions to closing as set forth in the Merger Agreement.
At the time of the consummation of the merger, Penril is responsible for payment
of the investment banking fees of approximately $1,300,000 and for change of
control payments of approximately $1,300,000 due to certain officers of Penril.
    
 
   
     LEASED FACILITIES:  Penril leases office and manufacturing facilities and
equipment under lease agreements, certain of which are renewable at Penril's
option and/or provide for increases in rent related to increases in the Consumer
Price Index and other factors. Rent expense for the fiscal years 1996, 1995 and
1994 was $1,673,000, $1,941,000 and $1,754,000 respectively. Approximate
aggregate future minimum rentals

     LEGAL PROCEEDINGS:  Penril is a party to several material legal proceedings
as summarized below. With the exception of the proceeding against Rockwell
International Corporation, et. al., and one other legal proceeding incurred in
connection with the modem business, all costs, expenses, liabilities and
obligations of the litigation will be assumed by Access Beyond in connection
with the Spin-off and all recoveries from such litigation will be realized by
Access Beyond; provided, however, that Penril may be deemed to have remained
contingently liable for satisfaction of the obligations.
    
   
     On June 1, 1993 Penril initiated a lawsuit against Standard Microsystems
Corp. ("SMC"), SMC Massachusetts, Inc., Ashraf M. Dahad and Kwabena Akufo (the
"SMC Defendants") in the Circuit Court of Maryland for Montgomery County for
breach of contract including, among other things, failure to transfer
technology, unfair competition and false representations. Penril sought relief
in an aggregate amount of approximately $50,000,000. The SMC Defendants
subsequently brought a counterclaim alleging fraud and breach of contract and
sought recovery of amounts due under the contract which were alleged to be
approximately $1,650,000 in compensatory damages plus unspecified punitive
damages. In September 1996, Penril and the SMC Defendants agreed to drop the
fraud charges and to settle the contractual dispute. Penril will receive from
SMC, in settlement of litigation, $3,500,000, net of legal payments, in the
first quarter of fiscal 1997.
    
   
     On December 24, 1994, Penril filed a complaint against Network Systems
Corporation of Minneapolis, Minnesota ("NSC") in the Circuit Court of Maryland
for Montgomery County. The litigation arises out of a contract in which Penril
agreed to develop certain computer hardware and software to NSC's
specifications. Penril alleges breach of contract, fraudulent inducement and
defamation and is seeking specific performance, compensatory damages of
$2,000,000 and punitive damages of $5,000,000. On March 28, 1995, NSC filed an
answer and counterclaim in which NSC alleges negligent misrepresentation, fraud
and breach of contract by Penril. NSC is seeking rescission of the contract,
restitution of monies paid by NSC to Penril, compensatory damages of $5,000,000
and punitive damages in an unspecified amount. As of July 31, 1996, the
litigation was in the discovery stage.
    
   
     Digital Equipment Corporation ("DEC") has claimed, through a series of
written communications, that Penril has violated DEC patents related to DEC LAT
technology. Penril has taken the position that Datability, prior to its
acquisition by Penril, had a relationship with DEC that involved the development
of LAT for which Datability has not collected. Both DEC and Penril have taken
the position that it is in the best interests of both parties to work toward a
fair resolution. As of July 31, 1996 no formal claims have been filed.
    
   
     On December 6, 1995, Penril filed a lawsuit against Rockwell International
Corporation and U.S. Robotics Access Corporation seeking declaratory,
injunctive, and money damage relief by reason of an alleged patent infringement
by the defendants. The action was filed in the United States District Court for
the District of Maryland. In September 1996, Penril agreed to settle its lawsuit
with U.S. Robotics.
    
   
     Penril is involved in other routine litigation.

     Management believes none of the litigation will have a material adverse
effect on Penril's financial position or results of operations.
    
 
   
8.  STOCKHOLDERS' EQUITY
    
 
   
     On September 22, 1995, Penril issued an aggregate of 1,465,000 shares of
its unregistered Common Stock to Pequot Partners Fund, L.P., Pequot Endowment
Fund, L.P and Pequot International Fund, Inc. (collectively the "Investors") for
$7,325,000 in a private transaction. As required by the Purchase Agreement
between the Investors and Penril, a shelf registration was filed with the
Securities and Exchange Commission which became effective on February 28, 1996.
The Investors may request one public shelf registration after the three years
until the later of September 22, 1999 or 30 days after Penril files its annual
report on Form 10-K for the fiscal year ended July 31, 1999. If Penril does not
keep the shelf registration effective for the required three years, the
Investors are entitled to require Penril to effect up to two public
registrations during that time. As part of the transaction, Penril has agreed to
increase the Board of Directors of Penril by one and, so long as the Investors
collectively own in the aggregate not less than 10% of the issued and
outstanding Common Stock, the Investors are entitled to fill such vacancy by
designating one person to the Board of Directors. In addition, on October 5,
1995, Penril completed the sale of 50,000 shares of its unregistered common
stock to Cramer Partners, L.P. for $250,000.
    
 
   
     In the second half of fiscal 1996, Penril issued 1,092,267 shares of its
unregistered common stock in an unrelated series of private placements which
generated $7,425,000.
    
 
   
     SERIAL PREFERRED STOCK:  Penril's Serial Preferred Stock may be issued in
one or more series. The shares of any series may be convertible into Common
Stock, may have priority over Common Stock in the payment of dividends and in
the distribution of assets in the event of liquidation or dissolution of Penril,
and may have preferential or other voting rights, all as determined by the Board
of Directors of Penril at the time it approves the series.
    
 
   
     EMPLOYEE STOCK OPTIONS AND STOCK AWARDS:  On December 13, 1995, Penril
adopted the 1995 Long-Term Stock Option Incentive Plan (the "1995 Plan") to
replace the 1986 Incentive Plan which expires on October 8, 1996. The
stockholders of Penril approved the 1995 Plan at the Annual Meeting held April
10, 1996. Under the 1995 Plan, which will terminate December 13, 2005, key
employees of Penril and its subsidiaries may be granted awards consisting of
non-qualified stock options, incentive stock options, and restricted stock
awards. The option price of shares of Common Stock will not be less than 100%
(110% in the case of incentive stock options granted to optionees holding more
than 10% of the voting stock of Penril at the date of grant) of the fair market
value of shares of Common Stock on the date of grant. No option will be
exercisable more than ten years (five years in the case of incentive stock
options granted to optionees holding more than 10% of the voting stock of Penril
on the date of grant) from the date it is granted. Penril has reserved 1,000,000
shares for issuance under the 1995 Plan. At July 31, 1996, employees had been
granted awards for 70,000 shares.
    
 
   
     In the case of a "change in control" of Penril, 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.
On July 2, 1996 Penril's Stock Option/Compensation Committee (the "Committee")
took action which caused all of the outstanding Penril options held by directors
and executive officers of Penril to vest.
    
 
   
     The terms of restricted stock awards granted under the 1995 Plan are
determined at the time of the award. Penril will hold the shares of Common Stock
under restricted stock awards until all restrictions lapse and such Common Stock
may not be sold or transferred by the employee until such time. The employee
must

be employed by Penril when the restrictions lapse in order to receive the shares
of Common Stock when the restrictions lapse.
    
 
   
     On October 8, 1986, Penril adopted the 1986 Incentive Plan (the "1986
Plan"). Under the 1986 Plan, which will terminate on October 8, 1996, key
employees of Penril and its subsidiaries may be granted awards consisting of
incentive stock options, non-qualified stock options, and restricted stock
awards. The option price of shares of Common Stock subject to options granted
under the 1986 Plan will not be less than 100% (110% in the case of incentive
stock options granted to optionees holding more than ten percent of the voting
stock of Penril at the date of grant) of the fair market value of shares of
Common Stock at the date of grant. No option will be exercisable more than ten
years (five years in the case of incentive stock options granted to optionees
holding more than ten percent of the voting stock of Penril on the date of
grant) from the date it is granted. At July 31, 1996 an aggregate of 964,538
shares of Common Stock were reserved for issuance under the 1986 Plan, of which
employees have been awarded grants for 962,951 shares of Common Stock.
    
 
   
     In the case of a "change in control" of Penril, 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.
On July 2, 1996 the Committee took action which caused all of the outstanding
Penril options held by directors and executive officers of Penril to vest.
    
 
   
     The terms of restricted stock awards ("Stock Awards") granted under the
1986 Plan are determined at the time of issuance and are evidenced by a written
restricted stock agreement. Any Stock Awards granted are subject to approval by
a majority of all "disinterested directors" as defined in Rule 16b-3 of the
General Rules and Regulations under the Securities Exchange Act of 1934, as
amended.
    
 
   
     On October 1, 1992, Penril granted Stock Awards, under the 1986 Plan for an
aggregate of 71,220 shares of Common Stock of Penril to employees of the
Gaithersburg, Maryland facility. The Stock Awards granted vested over two years
and employees had to be employed by Penril when the vested shares of Common
Stock were issued. Of the total shares of Common Stock awarded, 53,020 were
issued. Penril issued 29,560 shares of Common Stock in October, 1993 which
represented 50% of the Stock Awards outstanding on that date and the remaining
23,460 shares of Common Stock on October 1, 1994. Compensation related to the
Stock Award Program was amortized over the vesting period.
    
 
   
     NON-EMPLOYEE DIRECTOR STOCK OPTIONS:  On December 9, 1987, Penril adopted
the Non-Employee Directors' Stock Option Plan ("Directors Plan"). Under the
Directors Plan an option to purchase 24,000 shares of Common Stock is
automatically granted to each non-employee director of Penril on the first day
of his initial term. In addition, options to purchase shares of Common Stock are
automatically granted to each non-employee director on the fifth business day
after the Annual Report on Form 10-K is filed with the Securities and Exchange
Commission as follows: in each of the first two successive years after the
initial grant an option to purchase 6,000 shares of Common Stock is granted, and
in each of the next five successive years an option to purchase 3,000 shares of
Common Stock is granted. The option price per share of Common Stock of any
option granted under the Directors Plan is the fair market value of a share of
Common Stock on the date the option is granted. No option will be exercisable
more than ten years from the date of grant. An aggregate of 125,333 shares of
Common Stock were reserved for issuance under the Directors Plan at July 31,
1996, of which 92,000 shares of Common Stock have been granted. On July 2, 1996
the Committee took action which caused all of the outstanding Penril options
held by directors and executive officers of Penril to vest.

     In October 1992, Penril issued a warrant to purchase 166,000 shares of
Common Stock at $4.50 per share, the fair market value on the date of issuance,
to Coast Federal Savings Bank ("Coast") in settlement of a law suit brought

9.  RETIREMENT AND SAVINGS PLAN
    
 
   
     Penril'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 Penril 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, Penril to match employee contributions. In addition, Penril
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 Penril 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. Penril made matching contributions of $61,000, $45,000 and
$50,000 during fiscal 1996, 1995 and 1994, respectively. There were no
additional Penril contributions in any year. As part of the Transfer, the 401(k)
Plan will be transferred to Access Beyond and active participation in the 401(k)
Plan will be limited to eligible employees of Access Beyond. Access Beyond
intends to split up the 401(k) Plan so the portion of the plan representing the

provides no post-employment or post-retirement benefits.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
    
 
     Section 145 of the Delaware General Corporation Law ("DGCL") permits the
indemnification of the directors and officers of the Company. The By-laws of the
Company do not contain any provisions on indemnification.
 
   
     The Company's Restated Certificate of Incorporation (the "Company
Certificate") provides for the indemnification of directors and officers and
employees of the Company, and persons who serve or served at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred with respect to any action, suit or proceeding,
if such person acted in good faith and in a manner he reasonably believed to be
in or not opposed to the best interests of the Company and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful. The indemnification provisions set forth in the Company
Certificate do not preclude the indemnification of, and advancement of expenses
to, any other person to whom the Company has the power or obligation to
indemnify under the provisions of the DGCL, or otherwise. The right to
indemnification conferred in the Company Certificate is a contract right and
shall include the right to have paid by the Company the expenses incurred in
defending any such proceeding in advance of its final disposition. The Company
maintains insurance, at its expense, to protect itself and any director,
officer, employee or agent of the Company against any such expense, liability or
loss, whether or not the Company would have the power or the obligation to
indemnify such person against such expense, liability or loss under state law or
under the terms of the Company Certificate. Each director of the Company will
enter into an indemnification agreement with the Company (the "Indemnification
Agreements"). The Indemnification Agreements will provide that, subject to
certain exclusions, the Company will indemnify each director against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with any threatened,
pending or completed action, suit or proceeding to which such director is or is
threatened to be made a party by reason of his position as an officer or
director of the Company or who serves or served at the request of the Company as
a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, to the extent of the highest and most
advantageous of the indemnification provisions set forth in the Company
Certificate, the Company's By-laws, the DGCL, the laws of the jurisdiction under
which the Company exists, the terms of any liability insurance or any other
benefits available to such director.

ITEM 17.  UNDERTAKINGS.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions or otherwise, the registrants
have been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is therefore
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid
 
                                      II-2

by a director, officer or controlling person of the registrants in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrants will, unless in the opinion of their counsel the
matter has been settled by the controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by them is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

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


         THIS DISTRIBUTION AGREEMENT ("Agreement") is made and entered into this
_____ day of __________, 1996, by and between PENRIL DATACOMM NETWORKS, INC., a
Delaware corporation ("Penril"), and ACCESS BEYOND, INC., a Delaware corporation
("Access Beyond").

                                    RECITALS
                                    --------

   
         WHEREAS, Penril, Bay Networks, Inc., a Delaware corporation ("Bay") and
Beta Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of 
Bay ("Acquisition Corp.") have entered into an Agreement and Plan of
Reorganization and Merger dated as of June 16, 1996 as amended on August 5,
1996 (the "Merger Agreement") providing for the merger of Acquisition Corp.     
with and into Penril (the "Merger");

         WHEREAS, Penril desires to transfer to Access Beyond substantially all 
of the assets owned or used by Penril and its subsidiaries in the operation of
Penril's business other than its modem business (the "Business") including, but
not limited to, all of the contracts and agreements to which it is a party
relating to the operation of the Business (the "Assigned Assets") in exchange
for the issuance of a sufficient number of shares of common stock $.01 par   
value per shares of Access Beyond  ("Access Beyond Stock") to effect the
Distribution (as defined below); provided, however, that the Assigned Assets
shall not include those assets listed on EXHIBIT "A" attached hereto, which     
assets are owned or used by Penril and its subsidiaries in the operation of its
modem business, and Access Beyond desires to assume all debts, obligations,     
contracts or liabilities of Penril and its subsidiaries incurred in connection
with the Business (the "Assumed Liabilities") other than as specifically listed
on EXHIBIT "B" attached hereto;

         WHEREAS, immediately prior to the Effective Time (as defined in the
Merger Agreement), Penril's Board of Directors, subject to the approval of
Penril's stockholders, expects to distribute (the "Distribution") to the
holders of common stock, $.01 par value per share of Penril ("Company Stock")
on a one-share-for-one-share basis, all of the issued and outstanding Access
Beyond Stock; and
    

         WHEREAS, the purpose of the Distribution is to make possible the Merger
by divesting Penril of all of its businesses other than the modem business,
which modem business was the only business Bay desired to acquire.

         NOW, THEREFORE, in consideration of the above premises and of the
mutual undertakings and covenants set forth in this Agreement, and other good
and valuable consideration, the receipt, adequacy and sufficiency of which are
hereby acknowledged, Penril and Access Beyond, intending to be legally bound,
agree as follows:

   
        1. TRANSFER OF ASSETS. Prior to the Distribution, Penril will transfer  
to Access Beyond as of that date all of its and its subsidiaries rights, titles 
and interests in and to (i) the Assigned Assets and (ii) the Assumed
Liabilities and those employees of Penril other than those listed on Schedule 1
(the "Transfer"). Prior to the Distribution, Access Beyond will accept such
transfer and assume such liabilities.  The Transfer will be effected by means
of a bill of sale, assignment and assumption agreement, substantially in   
    


<PAGE>   2
the form of EXHIBIT "C" attached hereto, which Penril and Access Beyond hereby
agree to sign prior to the Distribution and prior to the Merger.

   
         2. ISSUANCE OF STOCK. In connection with, in consideration of and at
the time of the Transfer, Access Beyond hereby agrees to issue to Penril a
number of shares of Access Beyond Stock such that Penril will own a number of
shares of Access Beyond Stock equal to the number of shares of Company Stock
then outstanding.
    

         3. SETTLEMENT OF RECEIPTS. On a weekly basis, each party shall deliver
to the other any cash received which is properly the property of the other as
well as any mail packages or similar items so received.

   
         4. 401(K) PROFIT SHARING PLAN. As part of the Transfer, Penril will
transfer to Access Beyond and Access Beyond will assume Penril's 401(k) Profit
Sharing Plan, as amended (the "Plan"). Penril and Access Beyond shall at Access 
Beyond's sole cost and expense take all action as may be necessary or
appropriate to cause Access Beyond to assume sponsorship of the Plan and to
establish Access Beyond as successor of Penril as to all rights, duties,
liabilities and obligations under or with respect to the Plan. The parties
acknowledge that following the Transfer, active participation in the Plan will
be limited to eligible employees of Access Beyond. The parties acknowledge that
Access Beyond intends to split up the Plan so that the portion of the Plan
representing the benefits of participants not employed by Access Beyond can be
terminated. No provision of this Agreement shall be construed as a limitation
on the right of Access Beyond or Penril to amend the Plan or terminate its
participation therein which either would otherwise have under the terms of the
Plan or otherwise and no provision of this Agreement shall be construed to
create or create a right in any employee or beneficiary of such employee under
the Plan that such employee or beneficiary would not otherwise have under the
terms of the Plan itself.  Access Beyond hereby agrees to indemnify and hold
harmless Penril from any liabilities, costs, or expenses for the Plan, from and
after the Transfer.
    

   
         5. CHANGE IN CONTROL PAYMENTS. Notwithstanding anything to the
contrary contained herein, Penril shall retain, and shall  not transfer to
Access Beyond, funds sufficient to pay to Henry D. Epstein, Ronald A. Howard
and Richard D. Rose payments in the amount of $550,000, $562,000 and $150,000
respectively, which payments they are entitled as a result of the change in
control of Penril as result of the Merger. Penril hereby covenants and agrees
to make these payments at or prior to the consummation of the Merger.

         6. ACCESS TO INFORMATION. From and after the effective time of the
Transfer, each party shall afford to the other and its authorized accountant,
counsel or other designated representatives reasonable access and duplicating
rights during normal business hours to all books, records, contracts,
instruments, computer data and other information which relates to the assets or
liabilities or business of the other. Information may be required under this
Section 6 for, without limitation, audit, accounting, claims, litigation and tax
purposes as well as for purposes of fulfilling disclosure and reporting
obligations.
    

         Each party shall hold and shall cause its officers, employees, agents,
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 non-public information concerning the other
party furnished by such other party or its representatives pursuant to this
Agreement or which have been retained by such party and each party shall not
release or disclose such information to any other person, except its auditors,
attorneys, financial advisor, bankers and other consultants and advisors who
agree to be bound by the provisions of this Section 6. Each party shall be
deemed to have satisfied its obligation to hold confidential the information
concerning or supplied by the other party if it exercises the same care as it
takes to preserve confidential of its own similar confidential information.

         7. FURTHER ASSURANCES. Each party will, without further consideration,
at any time and from time to time after the date hereof, upon request of the
other party, promptly do, execute, acknowledge, obtain and deliver any and all
instruments as may reasonably be required for the purpose of vesting in Access
Beyond the full right, title and interest of Penril in the Assigned Assets,
enabling Access Beyond to perform its obligations under the Assigned Assets and
Assumed Liabilities and to carry out the intent and purposes of this Agreement.

         8. BINDING EFFECT. This Agreement will be binding upon and will inure
to the benefit of Penril and Access Beyond and their respective successors and
permitted assigns.

         9. MISCELLANEOUS. Captions and section headings are for convenience
only, are not a part of this Agreement, and may not in any way be used in
construing it. Any failure by any party to comply with any of the obligations
set forth in this Agreement may be waived by the other party, but any such
waiver must be in writing and will not be deemed a waiver of any other
obligation, agreement or condition contained in this Agreement.

                          PLAN AND AGREEMENT OF MERGER


              This Plan and Agreement of Merger entered into as of June 16, 1996
         by and among Bay Networks, Inc., a Delaware corporation (the "Buyer"),
         Beta Acquisition Corp., a Delaware corporation and a wholly-owned
         subsidiary of the Buyer (the "Transitory Subsidiary"), and Penril
         DataComm Networks, Inc., a Delaware corporation (the "Company"). The
         Buyer, the Transitory Subsidiary and the Company are referred to
         collectively in this Agreement as the "Parties".

              This Agreement contemplates a merger of the Transitory Subsidiary
         into the Company, which merger will qualify as a tax-free
         reorganization described in Section 368(a)(1)(B) of the Internal
         Revenue Code of 1986, as amended (the "Code"). In such merger, the
         stockholders of the Company will receive solely voting capital stock of
         the Buyer in exchange for their capital stock of the Company.

              The Parties acknowledge that in the event that the transactions
         contemplated by this Agreement are not consummated, the Company would
         experience a substantial loss and hardship; therefore, to minimize the
         potential for such (i) failure to consummate the transactions and (ii)
         loss and hardship, the Parties have knowingly agreed not to include in
         this Agreement many otherwise normal conditions to closing the
         transaction, including but not limited to, a condition that there shall
         be no material adverse change prior to the Effective Time (as defined
         below) to the Company, its business, financial condition, results of
         operations, or prospects, to the Company's industry or to the general
         business conditions.

              Now, therefore, in consideration of the representations,
         warranties and covenants in this Agreement contained, the Parties agree
         as follows.

                                    ARTICLE I

                                   THE MERGER

              1.1 The Merger. Upon and subject to the terms and conditions of
         this Agreement, the Transitory Subsidiary shall merge with and into the
         Company (with such merger referred to in this Agreement as the
         "Merger") at the Effective Time (as defined below). From and after the
         Effective Time, the separate corporate
<PAGE>   2
         existence of the Transitory Subsidiary shall cease and the Company
         shall continue as the surviving corporation in the Merger (the
         "Surviving Corporation"). The "Effective Time" shall be the time at
         which the Company and the Transitory Subsidiary file the certificate of
         merger or other appropriate documents prepared and executed in
         accordance with the relevant provisions of the Delaware General
         Corporation Law (the "Certificate of Merger") with the Secretary of
         State of the State of Delaware. The Merger shall have the effects set
         forth in Section 259 of the Delaware General Corporation Law.

              1.2 The Closing. The closing of the transactions contemplated by
         this Agreement (the "Closing") shall take place at a mutually agreed
         upon location, commencing at 9:00 a.m. local time on a mutually
         agreeable date as soon as practicable after the date on which all of
         the conditions to the obligations of the Parties to consummate the
         transactions contemplated by this Agreement have been satisfied or
         waived (the "Closing Date"), but in no event later than 150 days from
         the date hereof.

              1.3 Actions at the Closing. At the Closing, (a) the Company shall
         deliver to the Buyer and the Transitory Subsidiary the various
         certificates, instruments and documents referred to in Section 5.2, (b)
         the Buyer and the Transitory Subsidiary shall deliver to the Company
         the various certificates, instruments and documents referred to in
         Section 5.3, (c) the Company and the Transitory Subsidiary shall file
         with the Secretary of State of the State of Delaware the Certificate of
         Merger, and (d) the Buyer shall deliver a certificate for the Merger
         Shares (as defined below) to a bank, trust company or other entity
         reasonably satisfactory to the Company appointed by the Buyer to act as
         the exchange agent (the "Exchange Agent") in accordance with Section 
         1.7.

              1.4 Additional Action. The Surviving Corporation may, at any time
         after the Effective Time, take any action, including executing and
         delivering any document, in the name and on behalf of either the
         Company or the Transitory Subsidiary, in order to consummate the
         transactions contemplated by this Agreement.

              1.5 Conversion of Shares. At the Effective Time, by virtue of the
         Merger and without any action on the part of any Party or the holder of
         any of the following securities:

                   (a) Each share of common stock, $0.01 par value per share, of
         the Company ("Company Shares") issued and outstanding immediately prior
         to the Effective Time (other than Company Shares owned beneficially by
         the Buyer or the Transitory Subsidiary,


                                       -2-
<PAGE>   3
         Dissenting Shares (as defined below) and Company Shares held in the
         Company's treasury) shall be converted into and represent the right to
         receive (subject to the provisions of Section 1.9) such number of
         shares of common stock, $0.01 par value per share, of the Buyer ("Buyer
         Common Stock") as is equal to the Conversion Ratio (as defined below).
         The "Conversion Ratio" shall mean the number determined by dividing (i)
         $10.00 (ii) by the Buyer Stock Market Price. The "Buyer Stock Market
         Price" shall mean the average of the closing prices of the Buyer's
         Common Stock on the New York Stock Exchange (the "NYSE") five (5)
         consecutive trading days immediately preceding the second business day
         immediately preceding to the Closing Date. Stockholders of record of
         the Company ("Company Stockholders") shall be entitled to receive
         immediately all of the shares of Buyer Common Stock into which their
         Company Shares were converted pursuant to this Section 1.5(a) (the
         "Merger Shares").

                   (b) Each Company Share held in the Company's treasury
         immediately prior to the Effective Time and each Company Share owned
         beneficially by the Buyer or the Transitory Subsidiary shall be
         cancelled and retired without payment of any consideration therefor.

                   (c) Each share of common stock, $0.01 par value per share, of
         the Transitory Subsidiary issued and outstanding immediately prior to
         the Effective Time shall be converted into and thereafter evidence one
         share of common stock, $0.01 par value per share, of the Surviving
         Corporation.

              1.6  Dissenting Shares.

                   (a) For purposes of this Agreement, "Dissenting Shares" means
         Company Shares held as of the Effective Time by a Company Stockholder
         who has not voted such Company Shares in favor of the adoption of this
         Agreement and the Merger and with respect to which appraisal shall have
         been duly demanded and perfected in accordance with Section 262 of the
         Delaware General Corporation Law and not effectively withdrawn or
         forfeited prior to the Effective Time. Dissenting Shares shall not be
         converted into or represent the right to receive Merger Shares, unless
         such Company Stockholder shall have forfeited his right to appraisal
         under the Delaware General Corporation Law or withdrawn, with the
         consent of the Company, his demand for appraisal. If such Company
         Stockholder has so forfeited or withdrawn his right to appraisal of
         Dissenting Shares, then (i) as of the occurrence of such event, such
         holder's Dissenting Shares shall cease to be Dissenting Shares and
         shall be converted into and represent the right to receive the Merger
         Shares issuable in respect of such Company Shares pursuant to Section 
         1.5(a), and (ii) promptly following the


                                       -3-
<PAGE>   4
         occurrence of such event, the Buyer shall deliver to the Exchange Agent
         a certificate representing the Merger Shares to which such holder is
         entitled pursuant to Section 1.5(a).

                   (b) The Company shall give the Buyer (i) prompt notice of any
         written demands for appraisal of any Company Shares, withdrawals of
         such demands, and any other instruments that relate to such demands
         received by the Company and (ii) the opportunity to direct all
         negotiations and proceedings with respect to demands for appraisal
         under the Delaware General Corporation Law. The Company shall not,
         except with the prior written consent of the Buyer, make any payment
         with respect to any demands for appraisal of Company Shares or offer to
         settle or settle any such demands.

              1.7  Exchange of Shares

                   (a) Prior to the Effective Time, the Buyer shall appoint the
         Exchange Agent to effect the exchange for the Merger Shares of
         certificates that, immediately prior to the Effective Time, represented
         Company Shares converted into Merger Shares pursuant to Section 1.5
         (including any Company Shares referred to in the last sentence of
         Section 1.6(a)) ("Certificates"). On the Closing Date, the Buyer shall
         deliver to the Exchange Agent, in trust for the benefit of holders of
         Certificates, a stock certificate (issued in the name of the Exchange
         Agent or its nominee) representing the Merger Shares, as described in
         Section 1.5(a). As soon as practicable after the Effective Time, the
         Buyer shall cause the Exchange Agent to send a notice and a transmittal
         form to each holder of a Certificate (other than those surrendered and
         paid for at the Closing) advising such holder of the effectiveness of
         the Merger and the procedure for surrendering to the Exchange Agent
         such Certificate in exchange for the Merger Shares issuable pursuant to
         Section 1.5(a). Each holder of a Certificate, upon proper surrender
         thereof to the Exchange Agent in accordance with the instructions in
         such notice, shall be entitled to receive in exchange therefor (subject
         to any taxes required to be withheld) the Merger Shares issuable
         pursuant to Section 1.5(a). Until properly surrendered, each such
         Certificate shall be deemed for all purposes to evidence only the right
         to receive the Merger Shares issuable pursuant to Section 1.5(a).
         Holders of Certificates shall not be entitled to receive certificates
         for the Merger Shares to which they would otherwise be entitled until
         such Certificates are properly surrendered.

                   (b) If any Merger Shares are to be issued in the name of a
         person other than the person in whose name the Certificate surrendered
         in exchange therefor is registered, it shall be a condition to the
         issuance of such Merger Shares that (i) the Certificate so surrendered
         shall be transferable, and shall be


                                       -4-
<PAGE>   5
         properly assigned, endorsed or accompanied by appropriate stock powers,
         (ii) such transfer shall otherwise be proper and (iii) the person
         requesting such transfer shall pay to the Exchange Agent any transfer
         or other taxes payable by reason of the foregoing or establish to the
         satisfaction of the Exchange Agent that such taxes have been paid or
         are not required to be paid. Notwithstanding the foregoing, neither the
         Exchange Agent nor any Party shall be liable to a holder of Company
         Shares for any Merger Shares issuable to such holder pursuant to
         Section 1.5(a) that are delivered to a public official pursuant to
         applicable abandoned property, escheat or similar laws.

                   (c) In the event any Certificate shall have been lost, stolen
         or destroyed, upon the making of an affidavit of that fact by the
         person claiming such Certificate to be lost, stolen or destroyed, the
         Buyer shall issue in exchange for such lost, stolen or destroyed
         Certificate the Merger Shares issuable in exchange therefor pursuant to
         Section 1.5(a). The Board of Directors of the Buyer may, in its
         discretion and as a condition precedent to the issuance thereof,
         require the owner of such lost, stolen or destroyed Certificate to give
         the Buyer a bond in such sum as it may reasonably direct as indemnity
         against any claim that may be made against the Buyer with respect to
         the Certificate alleged to have been lost, stolen or destroyed.

                   (d) Promptly following the date which is six months after the
         Closing Date, the Exchange Agent shall return to the Buyer all Merger
         Shares in its possession, and the Exchange Agent's duties shall
         terminate. Thereafter, each holder of a Certificate may surrender such
         Certificate to the Buyer and, subject to applicable abandoned property,
         escheat and similar laws, receive in exchange therefor the Merger
         Shares issuable with respect thereto pursuant to Section 1.5(a).

              1.8 Dividends. No dividends or other distributions that are
         payable to the holders of record of Buyer Common Stock as of a date on
         or after the Closing Date shall be paid to former Company Stockholders
         entitled by reason of the Merger to receive Merger Shares until such
         holders surrender their Certificates in accordance with Section 1.7.
         Upon such surrender, the Buyer shall pay or deliver to the persons in
         whose name the certificates representing such Merger Shares are issued
         any dividends or other distributions that are payable to the holders of
         record of Buyer Common Stock as of a date on or after the Closing Date
         and which were paid or delivered between the Effective Time and the
         time of such surrender; provided that no such person shall be entitled
         to receive any interest on such dividends or other distributions.


                                        -5-
<PAGE>   6
              1.9 Fractional Shares. No certificates or scrip representing
         fractional Merger Shares shall be issued to former Company Stockholders
         upon the surrender for exchange of Certificates, and such former
         Company Stockholders shall not be entitled to any voting rights, rights
         to receive any dividends or distributions or other rights as a
         stockholder of the Buyer with respect to any fractional Merger Shares
         that would otherwise be issued to such former Company Stockholders. In
         lieu of any fractional Merger Shares that would otherwise be issued,
         each former Company Stockholder that would have been entitled to
         receive a fractional Merger Share shall, upon proper surrender of such
         person's Certificates, receive a cash payment equal to the closing
         price per share of the Buyer Common Stock on the NYSE, on the business
         day immediately preceding the business day prior to the Closing Date,
         multiplied by the fraction of a share that such Company Stockholder
         would otherwise be entitled to receive. The fractional share interests
         of each Company Stockholder will be aggregated, and no Company
         Stockholder will receive cash in an amount equal to or greater than the
         value of one full share of Buyer Common Stock.

              1.10 Options and Rights.

                   (a) As of the Effective Time, all obligations of the Company
         with respect to options to purchase Company Shares issued by the
         Company to the employees of the Company listed on Schedule 1.10
         pursuant to its stock option plans ("Options"), whether vested or
         unvested, shall be assumed by the Buyer.

                   (b) Immediately after the Effective Time, each Option
         outstanding immediately prior to the Effective Time shall be deemed to
         constitute an option to acquire, on the same terms and conditions as
         were applicable under such Option at the Effective Time, such number of
         shares of Buyer Common Stock as is equal to the number of Company
         Shares subject to the unexercised portion of such Option multiplied by
         the Conversion Ratio (with any fraction resulting from such
         multiplication to be rounded up or down to the nearest whole number or,
         in the case of .5, to the nearest odd number). The exercise price per
         share of each such Option shall be equal to the exercise price of such
         Option immediately prior to the Effective Time, divided by the
         Conversion Ratio. The term, exercisability, vesting schedule, status as
         an "incentive stock option" under Section 422 of the Code, if
         applicable, and all of the other terms of the Options shall otherwise
         remain unchanged. In addition to the foregoing, the applicable
         provisions of each award agreement for Options to be outstanding after
         the Effective Time will be equitably adjusted after the Spin-off
         Transaction and prior to the Closing by the Company's Board of
         Directors to reflect the Spin-off Transaction (as defined herein).


                                       -6-
<PAGE>   7
                   (c) As soon as practicable after the Effective Time, the
         Buyer or the Surviving Corporation shall deliver to the holders of
         Options appropriate notices setting forth such holders' rights pursuant
         to such Options, as amended by this Section 1.10, and the agreements
         evidencing such Options shall continue in effect on the same terms and
         conditions (subject to the amendments provided for in this Section 1.10
         and such notice).

                   (d) The Buyer shall take all corporate action necessary to
         reserve for issuance a sufficient number of shares of Buyer Common
         Stock for delivery upon exercise of the Options. As soon as practicable
         after the Effective Time, the Buyer shall file a Registration Statement
         on Form S-8 (or any successor form) under the Securities Act of 1933,
         as amended (the "Securities Act") with respect to all shares of Buyer
         Common Stock subject to such Options that may be registered on a Form
         S-8, and shall use its best efforts to maintain the effectiveness of
         such Registration Statement for so long as such Options remain
         outstanding.

                   (e) The Company shall obtain, prior to the Closing, the
         consent from each holder of an Option to the adjustment or amendment,
         as the case may be, of such Option or Right pursuant to this Section 
         1.10 (unless such consent is not required under the terms of the
         applicable agreement, instrument or plan).

              1.11 Certificate of Incorporation. The Certificate of
         Incorporation of the Surviving Corporation shall be the same as the
         Certificate of Incorporation of the Transitory Subsidiary immediately
         prior to the Effective Time, except that the name of the corporation
         set forth therein shall be changed to the name of the Company.

              1.12 By-laws. The By-laws of the Surviving Corporation shall be
         the same as the By-laws of the Transitory Subsidiary immediately prior
         to the Effective Time, except that the name of the corporation set
         forth therein shall be changed to the name of the Company.

              1.13 Directors and Officers. The directors of the Transitory
         Subsidiary shall become the directors of the Surviving Corporation as
         of the Effective Time. The officers of the Company shall remain as
         officers of the Surviving Corporation after the Effective Time,
         retaining their respective positions, except as specified by the Buyer
         pursuant to Section 5.2(g).

              1.14 No Further Rights. From and after the Effective Time, no
         Company Shares shall be deemed to be outstanding, and holders of
         Certificates shall cease to have any rights with respect thereto,
         except as provided in this Agreement or by law.


                                       -7-
<PAGE>   8
              1.15 Closing of Transfer Books. At the Effective Time, the stock
         transfer books of the Company shall be closed and no transfer of
         Company Shares shall thereafter be made. If, after the Effective Time,
         Certificates are presented to the Surviving Corporation or the Exchange
         Agent, they shall be cancelled and exchanged for Merger Shares in
         accordance with Section 1.5(a), subject to applicable law in the case
         of Dissenting Shares.

              1.16 Tax-Free Reorganization. The Parties intend to adopt this
         Agreement as a tax-free plan of reorganization and to consummate the
         Merger in accordance with the provisions of Section 368(a)(1)(B) of the
         Code. The Buyer represents and covenants that:

                   (a) The Surviving Corporation will pay its dissenting
         stockholders the value of their Dissenting Shares out of its own funds.
         No funds will be supplied for that purpose, directly or indirectly, by
         the Buyer, nor will the Buyer directly or indirectly reimburse the
         Surviving Corporation for any payments for Dissenting Shares.

                   (b) The Buyer presently intends, and at the Effective Time it
         will intend, to continue the Company's historic business or use a
         significant portion of the Company's historic business assets in a
         business.

                   (c) The Buyer has no plan or intention to liquidate the
         Surviving Corporation; to merge the Surviving Corporation into another
         corporation; to cause the Surviving Corporation to sell or otherwise
         dispose of any of its assets, except for dispositions made in the
         ordinary course of the Surviving Corporation's business; or to sell or
         otherwise dispose of any of the Company Shares acquired in the Merger,
         except for transfers described in Section 368(a)(2)(C) of the Code.

                   (d) The Buyer has no plan or intention to reacquire any Buyer
         Common Stock issued in the Merger.

                   (e) Neither the Buyer nor the Transitory Subsidiary is an
         investment company as defined in Section 368(a)(2)(F)(iii) and (iv)) of
         the Code.

                   (f) The payment of cash in lieu of fractional shares of Buyer
         Common Stock is solely for the purpose of avoiding the expense and
         inconvenience to the Buyer of issuing fractional shares and shall not
         represent separately bargained-for consideration. The total cash
         consideration that will be paid in the transaction to the Company
         Stockholders instead of issuing fractional shares of Buyer Common Stock
         will not exceed one


                                       -8-
<PAGE>   9
         percent of the total consideration that will be issued in the Merger to
         the Company Stockholders in exchange for their Company Shares. The
         fractional share interests of each Company Stockholder will be
         aggregated, and no Company Stockholder will receive cash in an amount
         equal to or greater than the value of one full share of Buyer Common
         Stock.

                   (g)  The Transitory Subsidiary is solely and directly
         owned by the Buyer.

                   (h) Neither the Buyer nor an affiliate of the Buyer has
         acquired Company Shares since June 1, 1991. The Buyer and its
         affiliates own no Company Shares. During the period from the date of
         this Agreement to the Effective Time, other than pursuant to this
         Agreement, neither the Buyer nor any affiliate of the Buyer shall
         acquire any Company Shares.

                                   ARTICLE II

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

              The Company represents and warrants to the Buyer that the
         statements contained in this Article II are true and correct, except as
         set forth in the disclosure schedule attached hereto (the "Disclosure
         Schedule"). The Disclosure Schedule shall be initialed by the Parties
         and shall be arranged in paragraphs corresponding to the numbered and
         lettered paragraphs contained in this Article II, and the disclosures
         in any paragraph of the Disclosure Schedule shall qualify only the
         corresponding paragraph in this Article II.

              2.1 Organization, Qualification and Corporate Power. The Company
         is a corporation duly organized, validly existing and in corporate and
         tax good standing under the laws of the state of its incorporation. The
         Company is duly qualified to conduct business and is in corporate and
         tax good standing under the laws of each jurisdiction in which the
         nature of the business described on Section 2.1 of the Disclosure
         Schedule (the "Modem Business") or the ownership or leasing of its
         properties relating to the Modem Business requires such qualification
         except where the failure to be so qualified would not have a material
         adverse effect on the Company and its Modem Subsidiaries (as defined
         below) taken as a whole. The Company has all requisite corporate power
         and authority to carry on the Modem Business in which it is engaged and
         to own and use the properties owned and used by it in the Modem
         Business. The Company has furnished to the Buyer true and complete
         copies of its Certificate of Incorporation and By-laws, each as amended
         and as in effect on the date hereof. The Company

         is not in violation of any provision of its Certificate of
         Incorporation or By-laws.

              2.2 Capitalization. The authorized capital stock of the Company
         consists of 20,100,000 shares, comprised of 20,000,000 shares of common
         stock, $.01 par value per share, of which 10,543,369 shares are issued
         and outstanding and no shares are held in the treasury of the Company,
         all as of June 6, 1996, and 100,000 shares of preferred stock, $0.01
         par value per share, of which no shares are designated or outstanding.
         Section 2.2 of the Disclosure Schedule sets forth a complete and
         accurate list as of June 6, 1996, of (i) all stockholders of record of
         the Company, indicating the number of Company Shares held by each
         stockholder, and (ii) all holders of Options, indicating the number of
         Company Shares subject to Options held by such holders. All of the
         issued and outstanding Company Shares are, and all Company Shares that
         may be issued upon exercise of Options in accordance with the terms
         thereof will be, duly authorized, validly issued, fully paid,
         nonassessable and free of all preemptive rights. There are no
         outstanding or authorized options, warrants, rights, agreements or
         commitments to which the Company is a party or which are binding upon
         the Company providing for the issuance, disposition or acquisition of
         any of its capital stock, other than as listed in Section 2.2 of the
         Disclosure Schedule. There are no outstanding or authorized stock
         appreciation, phantom stock or similar rights with respect to the
         Company. Except pursuant to this Agreement or the Affiliate Agreement
         (as defined herein), there are no agreements, voting trusts, proxies,
         or understandings with respect to the voting, or registration under the
         Securities Act, of any Company Shares other than as set forth in
         Section 2.2 of the Disclosure Schedule. All of the issued and
         outstanding Company Shares were issued in compliance with applicable
         federal and state securities laws.

              2.3 Authorization of Transaction. The Company has all requisite
         power and authority to execute and deliver this Agreement and to
         perform its obligations hereunder. The execution and delivery of this
         Agreement and, subject to the adoption of this Agreement and the
         approval of the Merger by a majority of the votes represented by the
         outstanding Company Shares entitled to vote on this Agreement and the
         Merger (the "Requisite Stockholder Approval"), the performance by the
         Company of this Agreement and the consummation by the Company of the
         transactions contemplated by this Agreement have been duly and validly
         authorized by all necessary corporate action on the part of the
         Company. This Agreement has been duly and validly executed and
         delivered by the Company and constitutes a valid and binding obligation
         of the Company, enforceable against the Company in accordance with its
         terms.

              2.4 Noncontravention. Subject to compliance with the applicable
         requirements of the Securities Act and any applicable state securities
         laws, the Securities Exchange Act of 1934, as amended (the "Exchange

         filing of requisite forms relating to the transfer of certain
         intellectual property rights of the Company (as contemplated by this
         Agreement) neither the execution and delivery of this Agreement by the
         Company, nor the consummation by the Company of the transactions
         contemplated by this Agreement (and, for clauses (b) and (d) of this
         Section 2.4, other than Spin-off Transaction), will (a) conflict with
         or violate any provision of the charter or By-laws of the Company, (b)
         require on the part of the Company or any corporation with respect to
         which the Company, directly or indirectly, has the power to vote or
         direct the voting of sufficient securities to elect a majority of the
         directors (a "Subsidiary") any filing with, or any permit,
         authorization, consent or approval of, any court, arbitrational
         tribunal, administrative agency or commission or other governmental or
         regulatory authority or agency (a "Governmental Entity"), other than
         any filing, permit, authorization, consent or approval which if not
         obtained or made would not have a material adverse effect on the
         assets, business, financial condition, results of operations or future
         prospects of the Company and its Subsidiaries relating to the Modem
         Business, taken as a whole, or on the ability of the Parties to

         of time or both) a default under, result in the acceleration of, create
         in any party the right to accelerate, terminate, modify or cancel, or
         require any notice, consent or waiver under, any contract, lease,
         sublease, license, sublicense, franchise, indenture, agreement or
         mortgage for borrowed money, instrument of indebtedness, Security
         Interest (as defined below) or other arrangement to which the Company
         or any Subsidiary is a party or by which the Company or any Subsidiary
         is bound or to which any of their assets is subject, other than any
         conflict, breach, default, acceleration, termination, modification or
         cancellation which individually or in the aggregate would not have a
         material adverse effect on the assets, business, financial condition,
         results of operations or future prospects of the Company and its
         Subsidiaries, taken as a whole, or on the ability of the Parties to
         consummate the transactions contemplated by this Agreement, (d) result
         in the imposition of any Security Interest upon any assets of the
         Company or any Subsidiary relating to the Modem Business or (e) violate

                                      -11-
<PAGE>   12
         Subsidiary or any of their properties or assets relating to the Modem
         Business. For purposes of this Agreement, "Security Interest" means any
         mortgage, pledge, security interest, encumbrance, charge, or other lien
         (whether arising by contract or by operation of law), other than (i)
         mechanic's, materialmen's, and similar liens, (ii) liens arising under
         worker's compensation, unemployment insurance, social security,
         retirement, and similar legislation, and (iii) liens on goods in
         transit incurred pursuant to documentary letters of credit, in each
         case arising in the ordinary course of business consistent with past
         custom and practice (including with respect to frequency and amount)
         ("Ordinary Course of Business") of the Company and not material to the
         Company.

              2.5 Subsidiaries. Section 2.5 of the Disclosure Schedule lists
         each Subsidiary and each Modem Subsidiary and sets forth for each Modem
         Subsidiary (a) its jurisdiction of incorporation, (b) the number of
         shares of authorized capital stock of each class of its capital stock,
         (c) the number of issued and outstanding shares of each class of its
         capital stock, the names of the holders thereof and the number of
         shares held by each such holder, (d) the number of shares of its
         capital stock held in treasury, and (e) its directors and officers.
         Each Modem Subsidiary is a corporation duly organized, validly existing
         and in good standing under the laws of the jurisdiction of its
         incorporation. Each Modem Subsidiary is duly qualified to conduct
         business and is in corporate and tax good standing under the laws of
         each jurisdiction in which the nature of its businesses or the
         ownership or leasing of its properties requires such qualification
         except where the failure to be so qualified would not have a material
         adverse effect on the Company and the Modem Subsidiaries taken as a
         whole. Each Modem Subsidiary has all requisite corporate power and
         authority to carry on the Modem Business in which it is engaged and to
         own and use the properties owned and used by it in the Modem Business.
         The Company has delivered or made available to the Buyer correct and
         complete copies of the charter and By-laws of each Modem Subsidiary, as
         amended to date. No Modem Subsidiary is in violation of any provision
         of its charter or By-laws. All of the issued and outstanding shares of
         capital stock of each Modem Subsidiary are duly authorized, validly
         issued, fully paid, nonassessable and free of preemptive rights. All
         shares of each Modem Subsidiary that are held of record or owned
         beneficially by either the Company or any Modem Subsidiary are held or
         owned free and clear of any restrictions on transfer (other than
         restrictions under the Securities Act and state securities laws or as
         set forth in Section 2.5 of the Disclosure Schedule), claims, Security
         Interests, options, warrants, rights, contracts, calls, commitments,
         equities and demands. There are no outstanding or authorized options,


                                      -12-
<PAGE>   13
         warrants, rights, agreements or commitments to which the Company or any
         Modem Subsidiary is a party or which are binding on any of them
         providing for the issuance, disposition or acquisition of any capital
         stock of any Modem Subsidiary. There are no outstanding stock
         appreciation, phantom stock or similar rights with respect to any Modem
         Subsidiary. There are no voting trusts, proxies, or other agreements or
         understandings with respect to the voting of any capital stock of any
         Modem Subsidiary, except as set forth in Section 2.5 of the Disclosure
         Schedule. The Company does not control directly or indirectly or have
         any direct or indirect equity participation in any corporation,
         partnership, trust, or other business association which is not a
         Subsidiary.

              2.6 Reports and Financial Statements. The Company has previously
         furnished or made available to the Buyer complete and accurate copies,
         as amended or supplemented, of its (a) Annual Report on Form 10-K for
         the fiscal years ended July 31, 1994, and July 31, 1995, as filed with
         the Securities and Exchange Commission (the "SEC"), (b) proxy
         statements relating to all meetings of its stockholders (whether annual
         or special) since July 31, 1994, and (c) all other reports or
         registration statements, other than Registration Statements on Form
         S-8, filed by the Company with the SEC since July 31, 1994 (such annual
         reports, proxy statements, registration statements and other filings,
         together with any amendments or supplements thereto, are collectively
         referred to in this Agreement as the "Company Reports"). The Company
         Reports constitute all of the documents filed or required to be filed
         by the Company with the SEC since July 31, 1994, other than any
         Registration Statement on Form S-8. As of their respective dates, the
         Company Reports filed since July 31, 1994, did not contain any untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein, in
         light of the circumstances under which they were made, not misleading.
         The audited financial statements and unaudited interim financial
         statements of the Company included in the Company Reports filed since
         July 31, 1994 (together, the "Financial Statements"), (i) comply as to
         form in all material respects with applicable accounting requirements
         and the published rules and regulations of the SEC with respect
         thereto, (ii) have been prepared in accordance with United States
         generally accepted accounting principles ("GAAP") applied on a
         consistent basis throughout the periods covered thereby (except as may
         be indicated therein or in the notes thereto, and in the case of
         quarterly financial statements, as permitted by Form 10-Q under the
         Exchange Act), (iii) fairly present the consolidated financial
         condition, results of operations and cash flows of the Company and the
         Subsidiaries as of the respective dates thereof and for the periods
         referred to


                                      -13-
<PAGE>   14
         therein, and (iv) are consistent with the books and records of the
         Company and the Subsidiaries.

              2.7 Undisclosed Liabilities. As of the date hereof, none of the
         Company and its Subsidiaries has any material liability (whether known
         or unknown, whether absolute or contingent, whether liquidated or
         unliquidated and whether due or to become due), except for (a)
         liabilities shown on the balance sheet included in the Company's most
         recent Quarterly Report on Form 10-Q filed with the SEC on March 15,
         1996 (the "Most Recent Balance Sheet"), (b) liabilities which have
         arisen since January 31, 1996, in the Ordinary Course of Business, (c)
         contractual liabilities incurred in the Ordinary Course of Business
         which are not required by GAAP to be reflected on a balance sheet and
         (d) liabilities disclosed in Section 2.18 of the Disclosure Schedule.
         As used in this Section 2.7, "material liability" is deemed to mean a
         liability in excess of $100,000.

              2.8  Tax Matters.

                   (a) Each of the Company and the Subsidiaries has filed all
         material Tax Returns (as defined below) that it was required to file
         (taking into account extensions) and to the knowledge of the Company no
         material position is reflected in a Tax Return for which there was not
         substantial authority (as defined in Section 6662 of the Code) or
         comparable foreign, federal, state or local law. Each of the Company
         and the Subsidiaries has paid all Taxes (as defined below) that are
         shown to be due on any such Tax Returns. The unpaid Taxes of the
         Company and the Subsidiaries for tax periods through the date of the
         Most Recent Balance Sheet are appropriately accrued or reserved for on
         the Most Recent Balance Sheet. Neither the Company nor any Subsidiary
         has any actual or potential liability for any Tax obligation of any
         taxpayer (including without limitation any affiliated group of
         corporations or other entities that included the Company or any
         Subsidiary during a prior period) other than the Company and the
         Subsidiaries. All material Taxes that the Company or any Subsidiary is
         or was required by law to withhold or collect have been duly withheld
         or collected and, to the extent required, have been paid to the proper
         Governmental Entity. For purposes of this Agreement, "Taxes" means all
         taxes, charges, fees, levies or other similar assessments or
         liabilities, including without limitation income, gross receipts, ad
         valorem, premium, value-added, excise, real property, personal
         property, sales, use, transfer, withholding, employment, payroll and
         franchise taxes imposed by the United States of America or any state,
         local or foreign government, or any agency thereof, or other political
         subdivision of the United States or any such government, and any
         interest, fines, penalties, assessments or additions to tax resulting
         from,


                                      -14-
<PAGE>   15
         attributable to or incurred in connection with any tax or any contest
         or dispute thereof. For purposes of this Agreement, "Tax Returns" means
         all reports, returns, declarations, statements or other information
         required to be supplied to a taxing authority in connection with Taxes.

                   (b) The Company has delivered to the Buyer correct and
         complete copies of all federal income Tax Returns, examination reports
         and statements of deficiencies assessed against or agreed to by any of
         the Company or any Subsidiary between January 1, 1989 and the date
         hereof. The federal income Tax Returns of the Company have been audited
         by the Internal Revenue Service (the "IRS") or are closed by the
         applicable statute of limitations for all taxable years through July
         31, 1986. As of the date hereof, no federal or state income tax
         examination or audit of any Tax Returns of the Company or any
         Subsidiary by any Governmental Entity is currently in progress or, to
         the knowledge of the Company and the Subsidiaries, threatened or
         contemplated. As of the date hereof, neither the Company nor any
         Subsidiary has waived any statute of limitations with respect to taxes
         or agreed to an extension of time with respect to a tax assessment or
         deficiency.

                   (c) Neither the Company nor any Subsidiary is a "consenting
         corporation" within the meaning of Section 341(f) of the Code and none
         of the assets of the Company or the Subsidiaries are subject to an
         election under Section 341(f) of the Code. Neither the Company nor any
         Subsidiary has been a United States real property holding corporation
         within the meaning of Section 897(c)(2) of the Code during the
         applicable period specified in Section 897(c)(l)(A)(ii) of the Code.
         Neither the Company nor any Subsidiary is a party to any Tax allocation
         or sharing agreement.

                   (d) Neither the Company nor any Subsidiary is or has ever
         been a member of an "affiliated group" of corporations (within the
         meaning of Section 1504 of the Code), other than a group of which only
         the Company and the Subsidiaries are members. Neither the Company nor
         any Subsidiary has made an election under Treasury Reg. Section

         (as defined in Section 414(c) of the Code), or (iii) an affiliated

         (iv) all annual reports filed on IRS Form 5500, 5500C or 5500R for the
         last three plan years for each Employee Benefit Plan, have been
         delivered or made available to the Buyer. Each Employee Benefit Plan
         has been administered in all material respects in accordance with its
         terms and each of the Company, the Subsidiaries and the ERISA
         Affiliates has in all material respects met its obligations with
         respect to such Employee Benefit Plan and has made all required
         contributions thereto. The Company has made no commitments to make any
         voluntary contributions to or to voluntarily fund any Employee Benefit
         Plans with the exception of 401(k) matching contribution commitments
         previously communicated to employees. The Company and all Employee
         Benefit Plans are in compliance in all material respects with the
         currently applicable provisions of ERISA and the Code and the
         regulations thereunder.

                   (b) There are no investigations by any Governmental Entity,
         termination proceedings or other claims (except claims for benefits
         payable in the normal operation of the Employee Benefit Plans and
         proceedings with respect to qualified domestic relations orders), suits
         or proceedings against or involving any Employee Benefit Plan or
         asserting any rights or claims to benefits under any Employee Benefit
         Plan that could give rise to any material liability.

                   (c) All the Employee Benefit Plans that are intended to be
         qualified under Section 401(a) of the Code have received determination
         letters from the Internal Revenue Service to the effect that such
         Employee Benefit Plans are qualified and the plans and the trusts
         related thereto are exempt from federal income taxes under Sections 
         401(a) and 501(a), respectively, of the Code, no such determination
         letter has been revoked and, to the knowledge of the Company, such
         revocation has not been threatened, and no such Employee Benefit Plan
         has been amended since the date of its most recent determination letter
         or application therefor in any respect, and, to the knowledge of the
         Company, no act or omission has occurred, that would adversely affect
         its qualification or materially increase its cost.

                   (d) Neither the Company, any Subsidiary, nor any ERISA
         Affiliate has, during the six years preceding the Effective Time,
         maintained an Employee Benefit Plan subject to Section 412 of the Code
         or Title IV of ERISA.

                   (e) At no time has the Company, any Subsidiary or any ERISA
         Affiliate been obligated to contribute to any "multi-employer plan" (as
         defined in Section 4001(a)(3) of ERISA).

                   (f)  There are no unfunded obligations under any
         Employee Benefit Plan providing benefits after termination of


                                      -21-
<PAGE>   22
         employment to any employee of the Company or any Subsidiary (or to any
         beneficiary of any such employee), including but not limited to retiree
         health coverage and deferred compensation, but excluding continuation
         of health coverage required to be continued under Section 4980B of the
         Code or state insurance law.

                   (g) To the knowledge of the Company, no act or omission has
         occurred and no condition exists with respect to any Employee Benefit
         Plan maintained by the Company, any Subsidiary or any ERISA Affiliate
         that would subject the Company, any Subsidiary or any ERISA Affiliate
         to any material fine, penalty, tax or liability of any kind imposed
         under ERISA or the Code.

                   (h) Except as set forth on Section 2.21(h) of the Disclosure
         Schedule, no Employee Benefit Plan is funded by, associated with, or
         related to a "voluntary employee's beneficiary association" within the
         meaning of Section 501(c)(9) of the Code.

                   (i) No Employee Benefit Plan, plan documentation or
         agreement, summary plan description or other written communication
         distributed generally to employees by its terms prohibits the Company
         or, if applicable, the Subsidiary or ERISA Affiliate, from amending or
         terminating any such Employee Benefit Plan.

                   (j) Section 2.21(j) of the Disclosure Schedule discloses
         each: (i) agreement with any director, executive officer or other key
         employee of the Company or any Subsidiary (A) the benefits of which are
         contingent, or the terms of which are materially altered, upon the

         determination of such person's "parachute payment" under Section 280G

         (vii) manufacture, processing, use, distribution, treatment, storage,
         disposal, transportation or handling of pollutants, contaminants,
         chemicals or toxic or hazardous substances or oil or petroleum products

         have been no releases of any Materials of Environmental Concern (as
         defined below) into the environment at any parcel of real property or
         any facility formerly or currently owned, operated or controlled by the
         Company or a Subsidiary. With respect to any such releases of Materials
         of Environmental Concern, the Company or such Subsidiary has given all
         required


                                      -23-

         notices to Governmental Entities (copies of which have been provided to
         the Buyer). Neither the Company nor any Subsidiary has any knowledge of
         any releases of Materials of Environmental Concern at any adjacent,
         adjoining or contiguous parcels of real property or facilities that
         could reasonably be expected to have a material adverse effect on the
         real property or facilities owned, operated or controlled by the
         Company or a Subsidiary. For purposes of this Agreement, "Materials of
         Environmental Concern" means any chemicals, pollutants or contaminants,
         hazardous substances (as such term is defined under CERCLA), solid
         wastes and hazardous wastes (as such terms are defined under the
         federal Resources Conservation and Recovery Act), toxic materials, oil
         or petroleum and petroleum products, or any other material subject to
         regulation under any Environmental Law.

                   (c) Set forth in Section 2.22(c) of the Disclosure Schedule
         is a list of all formal, written environmental reports, investigations
         and audits relating to premises currently or previously owned or
         operated by the Company or a Subsidiary (whether conducted by or on
         behalf of the Company or a Subsidiary or a third party, and whether
         done at the initiative of the Company or a Subsidiary or directed by a
         Governmental Entity or other third party) which were issued or
         conducted during the past five years and which the Company has
         possession of. Complete and accurate copies of each such report, or the
         results of each such investigation or audit, have been provided to the
         Buyer and any reliance by the Buyer on such reports, investigations or
         audits is at the Buyer's sole risk.

             2.23 Legal Compliance. Each of the Company and the Modem
         Subsidiaries, and the conduct and operations of their respective
         businesses, are in compliance with each law (including rules and
         regulations thereunder) of any federal, state, local or foreign
         government, or any Governmental Entity, which (a) affects or relates to
         this Agreement or the transactions contemplated by this Agreement or
         (b) is applicable to the Company or such Modem Subsidiary or such
         business, except for any violation of or default under a law referred
         to in clause (b) above which reasonably may be expected not to have a
         material adverse effect on the assets, business, financial condition,
         results of operations or future prospects of the Company and the Modem
         Subsidiaries taken as a whole.

             2.24 Permits. Section 2.24 of the Disclosure Schedule sets forth a
         list of all permits, licenses, registrations, certificates, orders or
         approvals from any Governmental Entity (including without limitation
         those issued or required under Environmental Laws and those relating to
         the occupancy or use of owned or leased real property) ("Permits")
         issued to or held by


                                      -24-
<PAGE>   25
         the Company or any Subsidiary relating to the Modem Business. Such
         listed Permits are the only Permits that are required for the Company
         and the Subsidiaries to conduct the Modem Business as presently
         conducted or as proposed by the Company to be conducted, except for
         those the absence of which would not have any material adverse effect
         on the assets, business, financial condition, results of operations or
         future prospects of the Company and the Modem Subsidiaries taken as a
         whole. Each such Permit is in full force and effect and, to the best of
         the knowledge of the Company or any Subsidiary, no suspension or
         cancellation of such Permit is threatened and there is no basis for
         believing that such Permit will not be renewable upon expiration. Each
         such Permit will continue in full force and effect following the
         Closing.

             2.25 Certain Business Relationships With Affiliates. Except as set
         forth in Section 2.25 of the Disclosure Schedule, no Affiliate of the
         Company (a) owns any property or right, tangible or intangible, which
         is used in the Modem Business, (b) has any claim or cause of action
         against the Company or any Modem Subsidiary other than in the Ordinary
         Course of Business, or (c) owes any money to the Company or any Modem
         Subsidiary. Section 2.25 of the Disclosure Schedule describes any
         transactions or relationships other than in the Ordinary Course of
         Business between the Company and any Affiliate thereof which are not
         reflected in the statements of operations of the Company included in
         the Financial Statements.

             2.26 Brokers' Fees. Except for the obligations of the Company to
         Broadview Associates, L.L.C. ("Broadview") pursuant to that certain
         Letter Agreement dated March 18, 1996, neither the Company nor any
         Subsidiary has any liability or obligation to pay any fees or
         commissions to any broker, finder or agent with respect to the
         transactions contemplated by this Agreement.

             2.27 Books and Records. The minute books and other similar records
         of the Company and each Modem Subsidiary contain true and complete
         records of all actions taken at any meetings of the Company's or such
         Subsidiary's stockholders, Board of Directors or any committee thereof
         and of all written consents executed in lieu of the holding of any such
         meeting. The books and records of the Company and each Modem Subsidiary
         accurately reflect in all material respects the assets, liabilities,
         business, financial condition and results of operations of the Company
         or such Subsidiary and have been maintained in accordance with good
         business and bookkeeping practices.

         Broadview, dated the date hereof, to the effect that the consideration

         opinion has been previously furnished to the Buyer.

         contained in this Agreement, and no statement contained in the
         Disclosure Schedule or any other document, certificate or other
         instrument delivered to or to be delivered by or on behalf of the

         misleading (provided that the Company shall not be responsible for the
         accuracy or completeness of any information furnished by the Buyer in
         writing for inclusion in the Prospectus/Proxy Statement, as to which
         information the Buyer shall ensure that the Prospectus/Proxy Statement
         does not, as of the date on which the Prospectus/Proxy Statement is

         and rules under the Securities Act and state securities laws in the
         preparation and filing of the Registration Statement and the offering
         and issuance of the Merger Shares. Without limiting the foregoing, the
         Buyer shall ensure that the Registration Statement does not, as of its
         effective date, contain an untrue statement of a material fact or omit
         to state a material fact required to be stated therein or necessary to
         make the statements therein not misleading (provided that the Buyer
         shall not be responsible for the accuracy or completeness of any
         information furnished by the Company in writing for inclusion in the
         Registration Statement, as to which information the Company shall
         ensure that the Registration Statement does not, as of its effective
         date, contain any untrue statement of a material fact or omit to state
         a material fact necessary in order to make the statements made, in
         light of the circumstances under which they were made, not misleading).

         below), the Company, acting through its Board of Directors, shall
         include in the Prospectus/Proxy Statement the recommendation of its

         required to file with the Federal Trade Commission and the Antitrust
         Division of the United States Department of Justice under the
         Hart-Scott-Rodino Act, shall use its best efforts to obtain an early
         termination of the applicable waiting period, and shall make any
         further filings or information submissions pursuant thereto that may be
         necessary, proper or advisable.

              4.6 Operation of Business. Except as contemplated by this

         2.10, 2.16 and 2.26 of

              4.7  Full Access.

         all premises, properties, financial and accounting records, contracts,
         other records and documents, and personnel, of or pertaining to the
         Company and each Subsidiary other than contracts, records and documents
         not relating to the Modem Business that the Company reasonably and in
         good faith determines is of a confidential and competitive nature. The

         Buyer and the Company.

              4.8 Notice of Breaches. The Company shall promptly deliver to the

         Disclosure Schedule) inaccurate or incomplete in any material respect,
         or (b) constitute or result in a breach by the Company of, or a failure
         by the Company to comply with, any agreement or covenant in this
         Agreement applicable to such party. The Buyer or the Transitory
         Subsidiary shall promptly deliver to the Company written notice of any
         event or development that would (i) render any statement,
         representation or warranty of the Buyer or the Transitory Subsidiary in
         this Agreement inaccurate or incomplete in any material respect, or
         (ii) constitute or result in a breach by the Buyer or the Transitory
         Subsidiary of, or a failure by the Buyer or the Transitory Subsidiary
         to comply with, any agreement or covenant in this Agreement applicable
         to such party. No such disclosure shall be deemed to avoid or cure any
         such misrepresentation or breach.

              4.9 Exclusivity. The Company shall not, and the Company shall use
         its best efforts to cause its Affiliates and each of its officers,

         discussions or negotiations with any person or entity (other than the
         Buyer) concerning any merger, consolidation, sale or license of
         material assets or property

         relating to the Modem Business, tender offer, recapitalization,
         accumulation of Company Shares, proxy solicitation or other business
         combination involving the Company, any Modem Subsidiary or any division
         of the Company or any Subsidiary, in each case relating to the Modem
         Business or (b) provide any non-public information concerning the
         business, properties or assets of the Company or any Subsidiary
         relating to the Modem Business to any person or entity (other than (i)
         to the Buyer, (ii) as contemplated by this Agreement, or (iii) as
         required by law or court order). Notwithstanding the foregoing or any
         other provision of this Agreement, neither the provisions contained in
         this Section 4.9 or elsewhere in this Agreement shall prohibit the
         Board of Directors of the Company from (i) furnishing information to or
         entering into discussions or negotiations with, any person or entity
         that makes an unsolicited bona fide written proposal to acquire the
         Company (or the Modem Business) pursuant to a merger, consolidation,
         share exchange, purchase of a substantial portion of the assets,
         business combination or other similar transaction, if the Board of
         Directors of the Company determines in good faith, based as to legal
         matters on the advice of counsel, that such action is required for the
         Board of Directors to comply with its fiduciary duties to stockholders
         imposed by law (the "Company Board Fiduciary Duties") and (ii)
         complying with Rule 14c-2 of the Exchange Act with regard to any
         Acquisition Proposal, if applicable, "Acquisition Proposal" shall mean
         any proposed (A) merger, consolidation or similar transaction involving
         the Company, (B) sale, lease or other disposition directly or
         indirectly by merger, consolidation, share exchange or otherwise of
         assets of the Company or the Subsidiaries representing 30% or more of
         the Modem Business or of the consolidated assets of the Company and the
         Subsidiaries, (C) issue, sale, or other disposition of (including by
         way of merger, consolidation, share exchange or any similar
         transaction) securities (or options, rights or warrants to purchase, or
         securities convertible into, such securities) representing 30% or more
         of the voting power of the Company or (D) transaction in which any
         person shall acquire beneficial ownership (as such term is defined in
         Rule 13d-3 under the Exchange Act), or the right to acquire beneficial
         ownership, or any "group" (as such term is defined under the Exchange
         Act) shall have been formed which beneficially owns or has the right to
         acquire beneficial ownership, of 30% or more of the outstanding Company
         Common Stock. The exercise of the Company Board Fiduciary Duties,
         notwithstanding any other provision of this Agreement, shall not
         constitute a breach or violation of any provision of this Agreement.
         The Company shall immediately notify the Buyer of, and shall disclose
         to the Buyer all details of, any inquiries, discussions or negotiations
         of the nature described in this Section 4.9.

              4.10 Agreements from Certain Affiliates of the Company.
         Concurrently with or prior to the execution of this Agreement, the
         Company shall deliver to the Buyer a list of all persons or entities
         who are at such time "affiliates" of the Company as that term is used
         in paragraphs (c) and (d) of Rule 145 under the Securities Act (the
         "Company Affiliates"). In order to help ensure that the issuance of
         Merger Shares will comply with the Securities Act and that the Merger
         will be treated as a tax-free reorganization, the Company shall use all
         reasonable efforts to cause each Company Affiliate to execute and
         deliver to the Buyer, prior to the distribution of the Prospectus/Proxy
         Statement in accordance with Section 4.4(b), a written agreement
         substantially in the form attached hereto as Exhibit B (the "Affiliate
         Agreement"). If any Company Affiliate fails to execute and deliver an
         Affiliate Agreement, the Buyer shall be entitled to place appropriate
         legends on the certificates evidencing the Merger Shares to be issued
         to such person or entity and any other shares of Buyer Common Stock
         issued to such person or entity upon exercise of an Option or Other
         Right, and to issue appropriate stock transfer instructions to the
         transfer agent for the Buyer Common Stock, to the effect that such
         shares may be sold publicly only in compliance with Rule 145 under the
         Securities Act.

              4.11 Listing of Merger Shares.  The Buyer shall list the
         Merger Shares on the NYSE.

              4.12 Indemnification; Release.

                   (a) From and after the Effective Time, the Buyer shall
         indemnify, defend and hold harmless the officers, directors and
         employees of the Company and the Subsidiaries (individually, an
         "Indemnified Party" and collectively, the "Indemnified Parties")
         against all losses, expenses, claims, damages or liabilities ("Claims")
         based on the fact that such person is or was such officer, director or
         employee of the Company or the Subsidiaries (including arising out of
         the transactions contemplated by this Agreement) to the fullest extent
         permitted or required under applicable law; provided, however, that no
         Indemnified Party shall be entitled to indemnification pursuant to this
         Section 4.12 for Claims based on the fact that such person is or was a
         stockholder of the Company. The Buyer agrees that all rights to
         indemnification existing in favor of the directors, officers or
         employees of the Company as provided in the Company's or the
         Subsidiaries' respective Articles or Certificate of Incorporation or
         By-Laws or Code of Regulations, as in effect as of the date hereof,
         with respect to matters occurring through the Effective Time, shall
         survive the Merger and shall continue in full force and effect for a
         period of not less than six years from the Effective Time and the Buyer
         hereby guaranties unconditionally the


                                      -37-
<PAGE>   38
         satisfaction of all such rights to indemnification (and shall pay
         expenses in advance of the final disposition of any such action or
         proceeding to each Indemnified Party to the fullest extent permitted
         under Delaware law, upon receipt from the Indemnified Party to whom
         expenses are advanced of the undertaking to repay such advances
         contemplated by Section 145(e) of the Delaware General corporation
         Law). Without limiting the foregoing, in the event any Claim is brought
         against any Indemnified Party (whether arising before or after the
         Effective Time) after the Effective Time (i) the Indemnified Parties
         may retain the Company's regularly engaged independent legal counsel or
         other independent legal counsel satisfactory to them, provided that
         such other counsel shall be reasonably acceptable to the Buyer, (ii)
         the Buyer shall pay all reasonable fees and expenses of such counsel
         for the Indemnified Parties promptly as statements therefor are
         received and (iii) the Buyer shall use its reasonable efforts to assist
         in the defense of any such matter, provided that the Buyer shall not be
         liable for any settlement of any Claim effected without its written
         consent, which consent shall not be unreasonably withheld. Any
         Indemnified Party wishing to claim indemnification under this Section 
         4.12, upon learning of any such Claim shall notify the Buyer (although
         the failure to so notify the Buyer shall not relieve the Buyer from any
         liability which the Buyer may have under this Section 4.12, except to
         the extent such failure materially prejudices the Buyer) and shall
         deliver to the Buyer the undertaking contemplated by Section 145(e) of
         the Delaware General Corporation Law. The Indemnified Parties as a
         group may retain no more than one law firm (in addition to local
         counsel) to represent them with respect to each such matter unless
         there is, under applicable standards of professional conduct (as
         determined by counsel to the Indemnified Parties), a conflict on any
         significant issue between the positions of any two or more Indemnified
         Parties, in which event such additional counsel as may be required may
         be retained by the Indemnified Parties and will be paid by the Buyer.

                   (b) The Buyer hereby remises and releases the directors,
         officers and employees of the Company from any and all claims it may
         have against them, other than claims based solely on fraud.

                   (c) The Company hereby remises and releases the directors,
         officers and employees of the Buyer from any and all claims it may have
         against them, other than claims based solely on fraud.

              4.13 Employee Matters.

                   (a)  With respect to benefit plans available to
         employees of the Company or the Modem Subsidiaries generally, for


                                      -38-
<PAGE>   39
         at least one year from and after the Effective Time, the Buyer shall
         cause the Surviving Corporation to either (i) maintain all employee
         benefits of the Company or the Modem Subsidiary, as the case may be,
         including, without limitation, benefits under employee benefit plans,
         policies and arrangements, existing on the Effective Time or (ii)

              8.8  Governing Law.  This Agreement shall be governed by and

              8.9 Amendments and Waivers. The Parties may mutually amend any
         provision of this Agreement at any time prior to the Effective Time;

         of any prior or subsequent such occurrence.

             8.10 Severability. Any term or provision of this Agreement that is
         invalid or unenforceable in any situation in any jurisdiction shall not
         affect the validity or enforceability of the remaining terms and
         provisions hereof or the validity or enforceability of the offending
         term or provision in any other situation or in any other jurisdiction.
         If the final judgment of a court of competent jurisdiction declares
         that any term or provision hereof is invalid or unenforceable, the
         Parties agree that the court making the determination of invalidity or
         unenforceability shall have the power to reduce the scope, duration, or
         area of the term or provision, to delete specific words or phrases, or
         to replace any invalid or unenforceable term or provision with a term
         or provision that is valid and enforceable and that comes closest to
         expressing the intention of the invalid or unenforceable term or
         provision, and this Agreement shall be enforceable as so modified after
         the expiration of the time within which the judgment may be appealed.

             8.11 Expenses. The Buyer and the Company shall each bear its own
         costs and expenses (including legal fees and expenses) incurred in
         connection with this Agreement and the transactions contemplated by
         this Agreement. The fees and expenses of the Company shall be accrued
         prior to the Closing Date and reflected on the Closing Balance Sheet.
         The fees and expenses of the Transitory Subsidiary shall be borne by
         the Buyer.

             8.12 Specific Performance. Each of the Parties acknowledges and
         agrees that one or more of the other Parties would be damaged
         irreparably in the event any of the provisions of this Agreement are
         not performed in accordance with their specific terms or otherwise are
         breached. Accordingly, each of the Parties agrees that the other
         Parties shall be entitled to an injunction or injunctions to prevent
         breaches of the provisions of this Agreement and to enforce
         specifically this Agreement and the terms and provisions hereof in any
         action instituted in any court of the United States or any state
         thereof having jurisdiction over the Parties and the matter (subject to
         the provisions of Section 8.13), in addition to any other remedy to
         which it may be entitled, at law or in equity.

             8.13 Submission to Jurisdiction. Each of the Parties (a) submits to
         the jurisdiction of any state or federal court sitting in Delaware in
         any action or proceeding arising out of or relating to this Agreement,
         (b) agrees that all claims in respect of the action or proceeding may
         be heard and determined in any such court, and (c) agrees not to bring
         any action or proceeding arising out of or relating to this Agreement
         in any other court. Each of the Parties waives any defense of
         inconvenient forum to the maintenance of any action or proceeding so
         brought and waives


                                      -48-

         any bond, surety or other security that might be required of any other
         Party with respect thereto. Any Party may make service on another Party
         by sending or delivering a copy of the process to the Party to be
         served at the address and in the manner provided for the giving of
         notices in Section 8.7. Nothing in this Section 8.13, however, shall
         affect the right of any Party to serve legal process in any other
         manner permitted by law.

             8.14 Construction. The language used in this Agreement shall be
         deemed to be the language chosen by the Parties hereto to express their
         mutual intent, and no rule of strict construction shall be applied
         against any Party. Any reference to any federal, state, local, or
         foreign statute or law shall be deemed also to refer to all rules and
         regulations promulgated thereunder, unless the context requires
         otherwise.

             8.15 Incorporation of Exhibits and Schedules. The Exhibits and
         Schedules identified in this Agreement are incorporated in this
         Agreement by reference and made a part hereof.

         survive the Closing, except for those contained in Article I and
         Sections 4.10 (the last sentence only), 4.12, 4.13, 4.14, 4.15 and 4.17
         and, to the extent relating to such specified provisions, those
         contained in this Article VIII.

         3.       The text of the Certificate of Incorporation as amended or 
supplemented heretofore is further amended hereby to read as herein set forth in
full:

         FOURTH:

         A.       GENERAL AUTHORIZATION.  The aggregate number of shares for all
classes of stock which the Corporation is authorized to issue is Thirty-Three 
Million (33,000,000) shares (the "Capital Stock"), consisting of:


                                        1

<PAGE>   2




                  1.       Thirty Million (30,000,000) shares of common stock, 
          par value $.01 per share ("Common Stock"); and

                  2.       Three Million (3,000,000) shares of preferred stock, 
          par value $.01 per share ("Preferred Stock").

         B.       TERMS OF COMMON STOCK. Except as otherwise provided in this
Certificate of Incorporation, each holder of Common Stock shall be entitled to
one vote for each share of Common Stock held by him on all matters submitted to
stockholders for a vote. Except as otherwise provided by law, the presence, in
person by proxy, of the holders of record of shares of Capital Stock entitling
the holders thereof to cast a majority of the votes entitled to be cast by the
holders of shares of Capital Stock entitled to vote shall constitute a quorum at
all meetings of the stockholders.

         C.       TERMS OF PREFERRED STOCK.

                  Shares of Preferred Stock may be issued from time to time in
one or more series, as provided for herein or as provided for by the Board of
Directors as permitted hereby. Each holder of Preferred Stock of any series that
is Voting Stock (as hereinafter defined) shall be entitled to such number of
votes for each share held by him as may be specified in the resolutions
providing for the issuance of such series. All shares of Preferred Stock shall
be of equal rank and shall be identical, except in respect of the terms fixed
herein for the series provided for herein or fixed by the Board of Directors for
series provided for by the Board of Directors as permitted hereby. All shares of
any one series shall be identical in all respects with all the other shares of
such series, except the shares of any one series issued at different times may
differ as to the dates from which dividends thereon may be cumulative.

                  The Board of Directors is hereby authorized, by resolution or
resolutions, to establish, out of the unissued shares of Preferred Stock not
then allocated to any series of Preferred Stock, additional series of Preferred
Stock. Before any shares of any such additional series are issued, the Board of
Directors shall fix and determine, and is hereby expressly empowered to fix and
determine, by resolution or resolutions, the distinguishing characteristics and
the relative rights, preferences, privileges and immunities of the shares
thereof, so far as not inconsistent with the provisions of this Article FOURTH.
Without limiting the generality of the foregoing, the Board of Directors may fix
and determine:

                           (a) The designation of and the number of shares of
                  Preferred Stock which shall constitute such series and the par
                  value, if any, of such shares; provided, that such number may
                  be increased (but not above the total number of authorized
                  shares of Preferred Stock) or decreased (but not below the
                  number of shares thereof then outstanding) from time to time 
                  by like action of the Board of Directors;

<PAGE>   3



                  
                           (b) The rate and time at which, and the terms and
                  conditions upon which, dividends, if any, on Preferred Stock
                  of such series shall be paid, the extent of the preference or
                  relation, if any, of such dividends to the dividends payable
                  on any other series of Preferred Stock or any other class of
                  stock of the Corporation and whether such dividends shall be
                  cumulative or non-cumulative and the dates from which any
                  cumulative dividends are to accumulate;

                           (c) The right, if any, of the holders of Preferred
                  Stock of such series to convert the same into, or exchange the
                  same for, shares of any other class of stock or any series of
                  any class of stock of the Corporation and the terms and
                  conditions of such conversion or exchange;

                           (d) Whether or not Preferred Stock of such series
                  shall be subject to redemption, and the redemption price or
                  prices and the time or times at which, and the terms and
                  conditions upon which, Preferred Stock of such series may be
                  redeemed;

                           (e) The rights, if any, of the holders of Preferred
                  Stock of such series upon the dissolution, liquidation or
                  winding-up of the Corporation, whether voluntary or
                  involuntary;

                           (f) The terms of the sinking fund or redemption or
                  purchase account, if any, to be provided for the Preferred
                  Stock of such series;

                           (g) The voting powers, if any, of the holders of such
                  series of Preferred Stock which may, without limiting the
                  generality of the foregoing, include the right, voting as a
                  series by itself or together with any other series of the
                  Preferred Stock as a class, (i) to vote more or less than one
                  vote per share on any or all matters voted by the
                  stockholders, and (ii) to elect one or more directors of the
                  Corporation if there has been a default in the payment of
                  dividends on any one or more series of the Preferred Stock or
                  under such other circumstances and upon such other condition
                  as the Board of Directors may fix;

                           (h) Whether the shares of such series of Preferred
                  Stock are to be preferred over shares of Capital Stock of the
                  Corporation of any other class or series as to dividends, or
                  upon the voluntary or involuntary dissolution, liquidation or
                  winding up of the affairs of the Corporation or otherwise; and

                           (i) Any other characteristics, preferences,
                  limitations, rights, privileges, immunities or terms not
                  inconsistent with the provisions of this Article FOURTH.

         D. TERMS RELATING TO ALL CLASSES OF STOCK. The Corporation may issue
shares of its Preferred Stock or Common Stock from time to time for such
consideration (not less than the par value thereof) as may be fixed from time to
time by the Board. Any and all shares so issued, for



                                        3

which such consideration has been paid or delivered to the Corporation, shall be
deemed fully paid shares and shall not be liable to any further call or
assessments thereon, and the holders of such shares shall not be liable for any
further payments in respect of such shares.

         FIFTH:   The name and mailing address of the Incorporator is 
                  as follows:

                  NAME                         MAILING ADDRESS
                  ----                         ---------------
         ACFB Incorporated                     2300 BP America Building
                                               200 Public Square
                                               Cleveland, Ohio 44114

         SIXTH:   The Corporation is to have perpetual existence.

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

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

         Subject to the rights of the holders of any class or series of the
Voting Stock then outstanding, any director, or the entire Board of Directors,
may be removed from office at any


                                        4

<PAGE>   5



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

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

         Notwithstanding the foregoing, whenever the holders of any one or more
classes or series of Preferred Stock issued by the Corporation shall have the
right, voting separately by class or series, to elect directors at an annual or
special meeting of stockholders, the election, term of office, filling of
vacancies and other features of such directorships shall be governed by the
terms of this Certificate of Incorporation applicable thereto (including the
resolutions of the Board of Directors pursuant to Article FOURTH), and such
Directors so elected shall not be divided into classes pursuant to this Article
SEVENTH unless expressly provided by such terms.

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

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

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

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

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

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

         NINTH: Meetings of stockholders may be held within or without the State
of Delaware, as the Bylaws may provide. The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
board of directors or in the bylaws of the Corporation. Elections of directors
need not be by written ballot unless the bylaws of the Corporation shall so
provide.

         TENTH: The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation. Notwithstanding any
other provisions of this Certificate of Incorporation or the By-laws of the
Corporation (and notwithstanding the fact that a lesser percentage or separate
class vote may be specified or permitted by law, this Certificate of
Incorporation or the By-laws of the Corporation), any proposal to amend or
repeal, or to adopt any provision of this Certificate of Incorporation
inconsistent with, Article SEVENTH or the first proviso of Article EIGHTH, shall
require the affirmative vote of the holders of not less than 80% of the votes
entitled to be cast by the holders of all the then-outstanding shares of voting
stock, voting together as a single class.

         ELEVENTH: No director shall be personally liable to the Corporation or
any of its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (1) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (2) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (3) under Section 174 of the Delaware General Corporation Law, or (4) for
any transaction from which the director derived an improper personal benefit. If
the Delaware General Corporation Law hereafter is amended to authorize the
further elimination or limitation of the liability of directors, then the
liability of a director of the Corporation, in addition to the limitations on
personal liability provided herein, shall be limited to the fullest extent
permitted by the Delaware General Corporation Law, as so amended from time to
time. Any repeal or modification of this Article shall be prospective only, and
shall not adversely affect any limitation

                                        6

<PAGE>   7



on the personal liability of a director of the Corporation existing at the time 
of such repeal or modification.

         TWELFTH: A. Subject to Section C of this Article TWELFTH, the
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Corporation) by reason of the fact that he
(i) is or was a director or officer of the Corporation, or (ii) is or was a
director or officer of the Corporation and is or was serving at the request of
the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interest of the
Corporation, or, with respect to any criminal action or proceeding, had
reasonable cause to believe his conduct was unlawful.

         B. Subject to Section C of this Article TWELFTH, the Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that he (i)
is or was a director or officer of the Corporation, or (ii) is or was a director
or officer of the Corporation and is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interest of the Corporation; except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

         C. Any indemnification of a director, officer, former director or
former officer of the Corporation under this Article TWELFTH (unless ordered by
a court) shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of said director or officer is
proper in the circumstances because he has met the applicable standard of
conduct set forth in Section A or Section B of this Article TWELFTH, as the case
may be. Such determination shall be made (i) by a majority vote of the directors
who are not parties to such action, suit or proceeding, even though less than a
quorum, or (ii) if there are no such

                                       7

<PAGE>   8



directors, or if such directors so direct, by independent legal counsel in a
written opinion, or (iii) by the stockholders. To the extent, however, that a
director or officer of the Corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding described in Section A or
Section B of this Article TWELFTH, or in defense of any claim, issue or matter
therein, he shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith, without the
necessity of authorization in the specific case.

         D. For purposes of any determination under Section C of this Article
TWELFTH, a person shall be deemed to have acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interest of the
Corporation, and, with respect to any criminal action or proceeding, to have had
no reasonable cause to believe his conduct was unlawful, if his action is based
on the records or books of account of the Corporation or another enterprise, or
on information supplied to him by the officers of the Corporation or another
enterprise in the course of their duties, or on the advice of legal counsel for
the Corporation or another enterprise or on information or records given or
reports made to the Corporation or another enterprise by an independent
certified public accountant or by an appraiser or other expert selected with
reasonable care by the Corporation or another enterprise. The term "another
enterprise" as used in this Section D of Article TWELFTH shall mean any other
corporation or any partnership, joint venture, trust or other enterprise of
which such person is or was serving at the request of the Corporation as a
director, officer, employee or agent. The provisions of this Section D shall not
be deemed to be exclusive or to limit in any way the circumstances in which a
person may be deemed to have met the applicable standard of conduct set forth in
Sections A or B of this Article TWELFTH as the case may be.

         E. Notwithstanding any contrary determination in the specific case
under Section C of this Article TWELFTH, and notwithstanding the absence of any
determination thereunder, any director or officer may apply to any court of
competent jurisdiction in the State of Delaware for indemnification to the
extent otherwise permissible under Sections A and B of this Article TWELFTH. The
basis of such indemnification by a court shall be a determination by such court
that indemnification of the director or officer is proper in the circumstances
because he has met the applicable standards of conduct set forth in Sections A
or B of this Article TWELFTH, as the case may be. Notice of any application for
indemnification pursuant to this Section E of Article TWELFTH shall be given to
the Corporation promptly upon the filing of such application.

         F. Expenses incurred in defending or investigating a threatened or
pending action, suit or proceeding may be paid by the Corporation in advance of
the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of the director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the Corporation as authorized in this Article TWELFTH.

         G. Subject to Section I of this Article TWELFTH, the Corporation may
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other


                                        8

<PAGE>   9



than an action by or in the right of the Corporation) by reason of the fact that
he is or was an employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interest of the
Corporation, or, with respect to any criminal action or proceeding, had
reasonable cause to believe his conduct was unlawful.

         H. Subject to Section I of this Article TWELFTH, the Corporation may
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that he is
or was an employee or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interest of the Corporation; except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

         I. Any indemnification of any employee, agent, former employee or
former agent of the Corporation under this Article TWELFTH (unless ordered by a
court) shall be made by the Corporation only as authorized in the sole
discretion of the Corporation. Such authorization shall be made (i) by a
majority vote of the directors who are not parties to such action, suit or
proceeding, even though less than a quorum, or (ii) if there are no such
directors, or if such directors so direct, by independent legal counsel in a
written opinion, or (iii) by the stockholders. To the extent, however, that an
employee or agent of the Corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding described in Section G or
Section H of this Article TWELFTH, or in defense of any claim, issue or matter
therein, he shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith, without the
necessity of authorization in the specific case.

         J. Expenses incurred in defending or investigating a threatened or
pending action, suit or proceeding may be paid by the Corporation, in its sole
discretion, in advance of the final


                                        9

<PAGE>   10



disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of the employee or agent to repay such amount if it shall
ultimately be determined that he is not entitled to be indemnified by the
Corporation as authorized in this Article TWELFTH.

         K. The indemnification and advancement of expenses provided by this
Article TWELFTH shall not be deemed exclusive of any other rights to which any
person seeking indemnification or advancement of expenses may be entitled under
any Bylaw, agreement, contract, vote of stockholders or disinterested directors
or pursuant to the direction (howsoever embodied) of any court of competent
jurisdiction or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office, it being the policy of the
Corporation that indemnification of, and advancement of expenses to, the persons
specified in Sections A and B of this Article TWELFTH shall be made to the
fullest extent permitted by law. The provisions of this Article TWELFTH shall
not be deemed to preclude the indemnification of, and advancement of expenses
to, any person who is not specified in Sections A or B of this Article TWELFTH
but whom the Corporation has the power or obligation to indemnify under the
provisions of the Delaware General Corporation Law, or otherwise. The
indemnification provided by this Article TWELFTH shall continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such person.

         L. The Corporation may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the Corporation,
or is or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him and incurred by him
in any such capacity, or arising out of his status as such, whether or not the
Corporation would have the power or the obligation to indemnify him against such
liability under the provisions of this Article TWELFTH.

         M. For purposes of this Article TWELFTH, reference to "the Corporation"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, employees or
agents, so that any person who is or was a director, officer, employee or agent
of such constituent corporation, or is or was serving at the request of such
constituent corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, shall stand
in the same position under the provisions of this Article TWELFTH with respect
to the resulting or surviving corporation as he would have with respect to such
constituent corporation if its separate existence had continued.

         THIRTEENTH: Whenever a compromise or arrangement is proposed between
this Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this Corporation under
the

                                       10

<PAGE>   11



provisions of Section 291 of the Delaware General Corporation Law or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this Corporation under the provisions of Section 279 of the Delaware General
Corporation Law, order a meeting of the creditors or class of creditors, and/or
of the stockholders or class of stockholders of this Corporation, as the case
may be, to be summoned in such manner as the said court directs. If a majority
in number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this Corporation as a consequence of such compromise or
arrangement, said compromise or arrangement and said reorganization shall, if
sanctioned by the court to which the said application has been made, be binding
on all the creditors or class of creditors, and/or on all the stockholders or
class of stockholders, of this Corporation, as the case may be, and also on this
Corporation.

         4. This Restated Certificate of Incorporation was duly adopted by

unanimous written consent of the stockholders in accordance with the applicable

provisions of Sections 228, 242 and 245 of the General Corporation Law of the

State of Delaware.

         IN WITNESS WHEREOF, Access Beyond, Inc. has caused this Certificate to

be signed by Henry D. Epstein, its President, this 25th day of September, 1996.

                                    ---------

                                  STOCKHOLDERS
                                  ------------

         Section 1. PLACE OF STOCKHOLDERS' MEETINGS. All meetings of the
stockholders of the Corporation shall be held at such place or places, within or
outside the State of Delaware, as may be fixed by the Board of Directors from

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


<PAGE>   2



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

         If for any reason a Board of Directors shall not be elected at the
Annual Meeting of Stockholders, or if it appears that such Annual Meeting is not
held on such date as may be fixed by the Directors in accordance with the
provisions of these By-laws, then in either such event the Directors shall cause
the election to be held as soon thereafter as convenient.

         Section 3. SPECIAL MEETINGS OF STOCKHOLDERS. Special meetings of the
stockholders entitled to vote may be called by the Chairman of the Board, if
any, the Vice Chairman of the Board, if any, the President or any Vice
President, the Secretary or by the Board of Directors, and shall be called by
any of the foregoing at the request in writing of stockholders owning a majority
in amount of the entire capital stock of the Corporation issued and outstanding
and entitled to vote. Such request shall state the purpose or purposes of the
meeting.

         Section 4. NOTICE OF MEETINGS OF STOCKHOLDERS. Except as otherwise
expressly required or permitted by the laws of Delaware, not less than ten (10)
days nor more than sixty (60) days before the date of every stockholders'
meeting the Secretary shall give to each stockholder of record entitled to vote
at such meeting written notice stating the place, day and hour of the meeting
and, in the case of a special meeting, the purpose or purposes for which the
meeting is called. Such notice, if mailed, shall be deemed to be given when
deposited in the United States mail, with postage thereon prepaid, addressed to
the stockholder at the post office address for notices to such stockholder as it
appears on the records of the Corporation.

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

         Section 5. QUORUM OF STOCKHOLDERS.

                  (a) Unless otherwise provided by the laws of Delaware, at any
         meeting of the stockholders the presence in person or by proxy of
         stockholders entitled to cast a majority of the votes thereat shall
         constitute a quorum.

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

         meeting other than announcement at the meeting shall not be required to
         be given, except as provided in paragraph (d) below and except where
         expressly required by law. 

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

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

exercise all of the powers of the Board in the management of the business and
affairs of the Corporation conferred by these By-laws or otherwise. The
Committee shall keep a record of all its proceedings and report the same to the
Board. A majority of the members of the Committee shall constitute a quorum. The
act of a majority of the members of the Committee present at any meeting at
which a quorum is present shall be the act of the Committee.

from among its members such other committees of two or more Directors as it may
from time to time deem desirable, and may delegate to such committees such

Board of Directors
Access Beyond, Inc.

Gaithersburg, Maryland 20878

Gentlemen:

         Access Beyond, Inc. (the "Company"), a Delaware corporation and
wholly-owned subsidiary of Penril Datacomm Networks, Inc. ("Penril"), has filed
with the Securities and Exchange Commission under the Securities Act of 1933, as
amended, a Registration Statement on Form S-1 (Registration No. 333-10741) (the
"Registration Statement") relating to the proposed distribution (the
"Distribution") of an aggregate of 11,993,000 shares of the Company's Common
Stock, par value $.01 per share (the "Common Stock") by Penril to holders of
record of Penril's Common Stock, par value $.01 per share, as of the close of
business on the record date to be set by the Board of Directors of Penril.

         You have requested our opinion in connection with the Company's filing
of the Registration Statement. In this connection, we have examined and relied
upon originals or copies, certified or otherwise identified to our satisfaction
as being true copies, of all such records of the Company, all such agreements,
certificates of officers of the Company and others, and such other documents,
certificates and corporate or other records as we have deemed necessary as a
basis for the opinions expressed in this letter, including, without limitation,
the Company's Restated Certificate of Incorporation, the Registration Statement,
and the related prospectus which forms a part of the Registration Statement (the
"Prospectus").

         In our examination, we have assumed the genuineness of all signatures,
the legal capacity of all natural persons, the authenticity of all documents
submitted to us as originals and the conformity to authentic original documents
of all documents submitted to us as certified or photostatic copies.

         We have investigated such questions of law for the purpose of rendering
the opinions in this letter as we have deemed necessary. We express no opinion
in this letter concerning any law other than the General Corporation Law of the
State of Delaware and the federal law of the United States of America.

         On the basis of and in reliance on the foregoing, we are of the opinion
that the Common Stock has been duly authorized and, when issued and delivered to
the stockholders of Penril pursuant to the Distribution, will be duly and
validly issued, fully paid and non-assessable.

         We consent to the filing of this letter as an exhibit to the
Registration Statement and to being named in the Prospectus under the heading
"Legal Matters" as counsel for the Company. The opinions in this letter are
rendered only to the Company in connection with the filing of the Registration
Statement. The opinions may not be relied upon by the Company for any other
purpose or relied upon by any other person, firm or entity for any purpose. This
letter may not be paraphrased, quoted or summarized, nor may it be duplicated or
reproduced in part.

Board of Directors of Penril DataComm Networks, Inc.
    
   
c/o Henry D. Epstein
    
   
Chairman of the Board
    
   
Penril DataComm Networks, Inc.
    
   
1300 Quince Orchard Boulevard
    
   
Gaithersburg, MD 20878
    
 
   
Gentlemen:
    
 
   
     You have requested our opinion as to whether (i) the proposed distribution
("Spin-off") by Penril DataComm Networks, Inc. ("Penril") to its shareholders of
100% of the outstanding stock of Access Beyond, Inc., a wholly-owned subsidiary
of Penril, will qualify as a tax-free spin-off pursuant to Section 355 of the
Internal Revenue Code of 1986, as amended (the "Code"), and (ii) the merger (the
"Merger") of Beta Acquisition Corp. with and into Penril, pursuant to which the
outstanding shares of common stock of Penril will be converted into the right to
receive common stock of Bay Networks, Inc. will qualify as a reorganization
within the meaning of Section 368(a)(1)(B) of the Code.
    
 
   
     In rendering this opinion, we have (with your permission) relied upon and
assumed as correct and complete the factual representations and information
contained in (i) the Management Certificates (attached hereto), (ii) the Plan
and Agreement of Merger entered into as of June 16, 1996, as amended on August
5, 1996, by and among Beta Acquisition Corp., Bay Networks, Inc. and Penril and
schedules thereto and (iii) a certain letter from Bay Networks, Inc. to Penril,
all dated as of June 16, 1996, and all other information, data, documentation
and materials presented to us during the course of our evaluation of the
Spin-off and Merger. We have also assumed that the Spin-off and the Merger
contemplated by such Plan and Agreement of Merger will be consummated as set
forth therein and as described in the preliminary proxy materials of Penril
dated August 8, 1996 and that the factual representations and material described
above will continue to be correct and complete as of the dates of the Spin-off
and the Merger. We have not undertaken to independently verify any of such facts
or information.

     Based on the foregoing, in our opinion it is more likely than not that (i)
the Spin-off will qualify as a nontaxable distribution under Section 355 of the
Code and (ii) the Merger will qualify as a reorganization within the meaning of
Section 368(a)(1)(B) of the Code.
    
 
   
     This opinion expresses our views only as to the federal income tax laws in
effect on the date hereof, including the Code, applicable treasury regulations,
published rulings, administrative practices of the Internal Revenue Service
("IRS") and published court decisions. No opinion is expressed with respect to
state, local, foreign or other tax laws. Moreover, this opinion does not relate
to or purport to cover any matters other than the ones expressly stated herein.
    
 
   
     This opinion represents our legal judgement as to the matters addressed
herein, but is not binding on the IRS (which may not agree with this opinion) or
any court. Accordingly, no assurance can be given that the opinion expressed
herein will not be contested by the IRS. Similarly, no assurance can be given
that the opinion expressed herein, if contested by the IRS, would be sustained
by a court. Furthermore, the authorities upon which we have relied are subject
to change, whether prospectively or retroactively, and any variation or
difference in the information presented to us might affect the conclusions
stated herein. Also, if the tax-free nature of the Merger is invalidated, it
would reduce the likelihood that the Spin-off will qualify as a tax-free
spin-off pursuant to Section 355 of the Code. We assume no obligation to revise
or supplement this opinion should the present federal income tax laws be changed
by any legislation, judicial decisions, or otherwise.
    
 
   
     This opinion is rendered only to Penril in connection with Access Beyond,
Inc.'s filing of its Registration Statement on Form S-1 and may not be relied
upon by any other person, firm or entity for any purpose without our express
written consent. We consent to the filing of this letter as an exhibit to the
Registration Statement and to being named in the Prospectus under the heading
"Legal Matters" as counsel for Access Beyond, Inc. Except for the discussion of
"Certain Federal Income Tax Consequences of the Distribution" in the Prospectus
forming a part of the Registration Statement, this letter may not be
paraphrased, quoted or summarized, nor may it be duplicated or reproduced in
part.

         Products and to apply each such modification or improvement to the
         Products, without payment to or the consent of the Licensor.

         Any such modification or improvement shall be the property of Licensee.

                  (b) Licensor agrees to provide Licensee with modifications and
         enhancements ("Enhancements") to the Licensed Technology on the
         following conditions:

                        (i) (A) Any such Enhancements shall be limited to ITU
                  approved changes to existing modem/fax related standards or
                  ITU approved new standards related to modem/fax devices, (B)
                  Licensor has determined to implement such changes or new
                  standards and (C) such changes or new standards are supported
                  by the hardware architecture incorporated in Licensor's modem
                  products as of the date of this Agreement; and

                        (ii) Licensee shall have no right to any Enhancement
                  that is not an ITU standard.

substantially all assets of Licensee, any single transaction or a series of
transactions of more than 50% of the capital stock of Licensee, or any merger,
consolidation or reorganization in which Licensee shall not be the surviving
corporation (an "Acquisition Transaction") Licensee shall be prohibited from
developing, manufacturing, marketing or otherwise using any new modem hardware
design which utilizes Licensors binary modem technology, except that minor
changes which may be required from time to time in Licensee's Products as they
existed at the time of such Acquisition Transaction shall not constitute new
modem hardware designs.

4.       OBLIGATIONS OF LICENSOR.

         4.1 TRAINING AND TECHNICAL ASSISTANCE. To assist Licensee in exercising
its rights hereunder, Licensor agrees to provide appropriate training and
technical assistance to Licensee, its employees and its permitted sublicensees,
so that Licensee will be able to practice the Patents and use the Licensed
Technology to its full potential. Such training and assistance shall be rendered
by Licensor at no expense to Licensee; PROVIDED, HOWEVER, that Licensor shall
not devote more than 80 man-hours during the term of this Agreement in rendering
such training and technical assistance to Licensee. The parties hereto shall
from time to time determine whether particular training and assistance shall be
rendered at Licensor's facilities or at Licensee's facilities. Travel costs,
lodging and all related expenses incurred by one party in connection with
sending its employees or permitted sublicensees to the other party's location
shall be paid in full by the party sending such individuals.

compatible cards.

5.       COMPENSATION PAYABLE TO LICENSOR.

         5.1 ROYALTIES. Licensee agrees to pay a royalty to Licensor on the
following basis: to the extent that (i) Licensor enters into cross licensing
agreements involving the University of Maryland patent described in Exhibit C-1,
and (ii) the technology covered by such license is integrated into the Product,
a royalty equal to the per modem royalty rate which Licensor pays (if any) as a
result of such cross license for each and every modem per Product that Licensee
or any Affiliate of Licensee or any of their permitted sublicensees or assigns
manufactures, sells, leases, licenses, or otherwise transfers for value.

         5.2 REPORTS; PAYMENT. Licensee shall deliver to Licensor no later than
forty five (45) days after the end of each calendar quarter during the term of
this Agreement, a written report describing: (i) the number of Products
manufactured, sold, licensed, leased or otherwise transferred in accordance with
Section 5.1 above during such calendar quarter, and (ii) the amount of the
royalty payable to Licensor for such calendar quarter. Each report shall be
accompanied by payment of the amount of royalties payable under Section 5.1 with
respect to such calendar quarter. All payments shall be made in U.S. dollars. No
part of any amount payable to Licensor hereunder may be reduced due to any
counterclaim, set-off, adjustment or other right which Licensee might have
against Licensor, any other party or otherwise. Notwithstanding the foregoing,
if Licensee issues a credit for any returned Product, then no 5.1 sale-based
royalty shall be payable in respect thereof and if a royalty was previously
paid, then Licensee shall be entitled to an equal credit against the next
royalty payment.

         5.3 LICENSEE'S BOOKS AND RECORDS. Licensee agrees to make and keep
full and accurate books and records in sufficient detail to enable royalties
payable hereunder to be determined.

         5.4 LICENSOR'S RIGHT TO AUDIT. Licensor and its certified public
accountants and other auditors shall have full access during normal business
hours and on reasonable notice to the books and records of Licensee pertaining
to activities under this Agreement and shall have the right to make copies
therefrom. Prompt adjustment shall be made by the proper party to compensate for
any errors or omissions disclosed by such audit. The cost of any such audit
shall be borne by Licensor unless such audit reveals a discrepancy of more than
10% with respect to any calendar quarter in the amount of royalties paid to
Licensor and the amount shown by such audit to be due, in which event the cost
of such audit shall be borne by Licensee.

         5.5 AUDIT INFORMATION CONFIDENTIAL. Licensor agrees to hold
confidential all information learned in the course of any examination of
Licensee's books and records hereunder, except when it is necessary for Licensor
to reveal such information in order to enforce its rights under this Agreement
in court, or similar dispute resolution or enforcement proceeding or action, or
except when compelled by law.

6.       WARRANTY.

         6.1 WARRANTY. Licensor makes no warranty whatsoever with respect to the

any other party or otherwise. Notwithstanding the foregoing, if Licensee issues
a credit for any returned Product, then no 5.2 royalty shall be payable in
respect thereof and if a royalty was previously paid, then Licensee shall be

Licensor and the amount shown by such audit to be due, in which event the cost
of such audit shall be borne by Licensee.

         5.6 AUDIT INFORMATION CONFIDENTIAL. Licensor agrees to hold
confidential all information learned in the course of any examination of
Licensee's books and records hereunder, except when it is necessary for Licensor

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

The 24 Digital Modem card, defined in EXHIBIT B, shall be developed by Licensor
as a high priority project progressing at no less speed than the speed with
which Licensor executes its own digital modem development project(s).

Licensor agrees to deliver five (5) hardware prototypes of the 24 Digital Modem
Card to Licensee. To the extent that the hardware for such card is completed
prior to the availability of fully functioning digital modem software, and

shall deliver such prototypes to Licensee with limited function software at such
earliest time so as to allow Licensee to complete dependent related work within
its own products. From time to time, Licensor shall supply Licensee with updated
software that adds further functionality until the full required functionality
has been achieved.

From delivery by Licensor of the required prototypes to Licensee together with
fully functioning software, Licensee shall have thirty (30) days to accept such
prototypes (the "Acceptance Period"). Any nonconformances discovered by Licensee
during the Acceptance Period shall be reported to Licensor for verification and
appropriate action will be taken promptly, during which time the Acceptance
Period shall be extended.

Mark Silverman is hereby designated the Project Manager for Licensee.

                                    EXHIBIT B
                                    ---------
                                    PRODUCTS
- ------------------------------------

Licensor will develop for Licensee a 24 Digital Modem Card compatible with and
capable of operating together within Licensee's AB product family. Such modem
architecture shall be compatible with and deliver the functions and capabilities
contained within Licensor's Digital Modem Developer's kit, which is attached
herein as part of this EXHIBIT B. Licensor shall deliver to Licensee prototype
cards as defined in Exhibit A demonstrating partial and subsequently full
conformance to such functionality when used with Access Beyond, Inc.'s
equipment.

The hardware design of the card will be implemented so as to allow Licensee,
independently from Licensor, to subsequently design and manufacture hardware
variations of the card based on Licensor's initial design that utilize differing
numbers of modems per card. The software utilized on the card will automatically
sense the number of modems available and adjust appropriately, minimizing
support work for Licensor and manufacturing complexity for Licensee.

Licensor has advised Licensee that it believes that 24 digital modems will fit
on one of Licensee's AB cards based on development strategies that Licensor
expects to develop and utilize. If it is subsequently determined, factoring in
the projected cost per modem and/or time to market considerations of the
proposed implementation strategy, that such high density card implementation is
not feasible or is too costly to Licensee then Licensee may alter the
specification and request that Licensor instead implement a 16 digital modem
card in place of the 24 digital modem card.

         actions or administrative hearings existing on the date hereof to which
         Penril is a party (or which have been assigned by Penril to Newsub and
         assumed by Newsub) other than those based upon, arising out of or in
         connection with the Modem Business (collectively, the "Newsub Existing
         Litigation", as listed on Exhibit A hereto). This Agreement will
         constitute notice, in accordance with Paragraph 2 hereof, of Newsub's
         election to conduct the defense (or to prosecute, as the case may be)
         of all claims in connection with the Newsub Existing Litigation. 
         Other than certain rights retained pursuant to Paragraph 2 hereof

         without limitation, reasonable legal fees and expenses) resulting from
         or attributable to (i) the operation of Penril from and after the

<PAGE>   4


         Exchange Commission to register the Newsub Stock in connection with the
         Distribution or any information concerning Newsub in the Registration
         Statement that was furnished by Penril and/or Newsub for inclusion in
         the Registration Statement. In furtherance thereof, Penril acknowledges
         and agrees that (ii) above includes, but is not limited to, all suits,
         actions or administrative hearings existing on the date hereof to which
         Penril is a party (none of which have been assigned by Penril to Newsub
         or assumed by Newsub) which are based upon, arising out of or in
         connection with the Modem Business (collectively, the "Penril Retained
         Existing Litigation", as listed on Exhibit B hereto, and, together with
         the Newsub Existing Litigation, the "Existing Litigation"). This
         Agreement will constitute notice, in accordance with Paragraph 2
         hereof, of Penril's election to conduct the defense (or to prosecute,
         as the case may be) of all claims in connection with the Penril
         Retained Existing Litigation. Other than certain rights retained
         pursuant to Paragraph 2 hereof Newsub acknowledges and agrees that
         Penril will have all rights to, and title and interest in any such
         claim, suit or proceeding for which Penril is providing
         indemnification.

         2.       DEFENSE OF CLAIM.

                  (a) In the event an Indemnified Party receives notice of any
         claim asserted or any action or administrative or other proceeding
         commenced in respect of a Claim for which indemnity may be properly
         sought under this Agreement against Newsub or Penril, as the case may
         be (the "Indemnifying Party"), the Indemnified Party shall give notice
         in writing to the Indemnifying Party within thirty (30) days of its
         receipt of such notice. Within thirty (30) days after the earlier of
         (a) receipt by the Indemnifying Party of such notice from the
         Indemnified Party, or (b) receipt of actual notice by the Indemnifying
         Party from sources other than the Indemnified Party, the Indemnifying
         Party may give the Indemnified Party written notice of its election to
         conduct the defense of such claim, action or proceeding at its own
         expense. If the Indemnifying Party has given the Indemnified Party such
         notice of election to conduct the defense, the Indemnifying Party may
         conduct the defense at its expense, but the Indemnified Party shall
         nevertheless have the right to participate in the defense, provided
         such participation is solely at the expense of the Indemnified Party,
         without a right of further reimbursement. If the Indemnifying Party 


<PAGE>   5


         has not so notified the Indemnified Party in writing within the
         time period provided above of its election to conduct the defense of
         such Claim, the Indemnified Party may, but need not, conduct, at the
         Indemnifying Party's expense, the defense of such claim, action or
         proceeding. The Indemnified Party may at any time notify the
         Indemnifying Party of its intention to settle, compromise or satisfy
         any such claim, action or proceeding (the defense of which the
         Indemnifying Party has not previously elected to conduct) and, with
         the prior written consent of the Indemnified Party (which consent will
         not be unreasonably withheld), may make such settlement, compromise or
         satisfaction, at the Indemnifying Party's expense, provided, however,
         that the Indemnifying Party may make such settlement, compromise or
         satisfaction without the prior written consent of the Indemnified
         Party if such settlement, compromise or satisfaction constitutes a
         release of the Indemnified Party in respect of such    Claim.

                  (b) Any settlement, compromise or satisfaction, or any final
         judgment or decree entered in, any Claim or Existing Litigation
         defended in accordance with the provisions of this Paragraph 2 shall be
         final and binding on the parties hereto.

                  (c) The Indemnified Party and the Indemnifying Party shall use
         all reasonable efforts to cooperate fully with respect to the defense
         of any Claim or Existing Litigation in accordance with the provisions
         of this Paragraph 2.

         3. NOTICE. All notices and other communications required or permitted
to be given under this Indemnification Agreement shall be dated and in writing
and shall be deemed to have been duly given when (a) personally delivered, (b)
upon delivery of a telephonic facsimile transmission with a confirmed telephonic
transmission answered back, (c) three days after being deposited in the United
States mail, registered or certified, return receipt requested, postage prepaid,
or (d) one day after having been dispatched by a nationally recognized overnight
courier service, addressed to the party or parties to this Agreement to whom it
is directed:

         Sublessor shall give Sublessee possession of the Subleased Premises on
the Commencement Date, and thereafter, as described herein, on an "AS IS" basis,

                                    ---------

   
         Sublessee agrees to pay to Landlord, on behalf of Sublessee and
Sublessor, as base rent for the Subleased Premises during the Sublease Term
monthly rentals equal in amount to the "Basic Monthly Rental" or "Base Rent" as
set forth and defined in Section 3 of the Lease, to the same extent as if

         All rentals due hereunder shall be paid directly by Sublessee to

                          CREDIT FOR LAST MONTH'S RENT
                          ----------------------------

         Sublessor and Sublessee acknowledge and agree that pursuant to the
provisions of Section 6 of the Lease, Sublessor has deposited with Landlord the
sum of Sixty-two Thousand Eight Hundred Thirty and 73/100 Dollars ($62,830.73)
as Basic Monthly Rent for the last month of the Term of the Lease. Sublessor and
Sublessee further acknowledge and agree that it is the intention of the parties
that Sublessee shall be entitled to a credit under this Sublease for such amount
to the same extent as if such deposit in such amount had been made by Sublessee
with Sublessor pursuant to this Sublease. By reason thereof, in the event the
Sublease Term expires or this Sublease is otherwise terminated, such amount
shall be credited toward the payment of the last month's rent due from Sublessee
to Sublessor under the terms of this Sublease. In the event that this Sublease
shall be terminated for any reason other than default or breach by Sublessee,
then, to the extent that the amount of such deposit exceeds the applicable
rental for the last valid month of this Sublease prior to such termination, such
excess shall be credited by Sublessor to Sublessee, and an amount in cash equal
to such excess shall be delivered promptly by Sublessor to Sublessee.


                                   ARTICLE VI
                                   ----------
                         USE AND ENVIRONMENTAL COVENANTS
                         -------------------------------

         1. Sublessee shall use the Premises for general office use, planning,
engineering, design, development and implementation of products and services
(excluding heavy manufacturing), computer operations, software and hardware
development and light assembly and storage reasonably related to such uses, and
for such other lawful purposes as may be incidental thereto, and Sublessee will
not utilize the Premises for any manufacturing purposes or any other purposes
whatsoever. Notwithstanding the above, Sublessee shall not do or permit anything
to be done in or about the Premises which will allow the Premises to be used for
any improper, immoral, unlawful or objectionable purpose, nor shall Sublessee
cause, maintain or permit any nuisance in, on or about the Premises. Sublessee
shall not commit or suffer to be committed any waste in or upon the Premises.
Sublessee shall be responsible for obtaining, at Sublessee's sole expense, any
and all necessary permits and approvals required in order for Sublessee to use
and occupy the Premises as set forth herein.

         2. Sublessee shall not occupy, use or permit to be used or occupied the
Premises in violation of any applicable law, governmental rule, regulation or
order including, without limiting

                                        3

<PAGE>   4



the generality of the foregoing, all laws, rules, regulations and orders
relating to the health and safety of employees and the pollution of the
atmosphere and surface or ground waters. Sublessee shall not permit any
"Hazardous Material" (as hereinafter defined or as otherwise set forth in
Section 9 of the Lease) of any kind or nature to be disposed of, released,
accumulated, buried or stored in, on or about the Premises. Further, Sublessee
shall take all actions necessary to keep the Premises free from contamination by
or from any such Hazardous Material. As used herein, the term "Hazardous
Material" means any hazardous or toxic substance, material or waste which is or
becomes regulated by any local governmental authority, the State of Maryland or
the United States Government. The term "Hazardous Material" includes also,
without limitation, any material or substance which is (a) designated as a
"hazardous substance" pursuant to Section 311 of the Federal Water Pollution
Control Act (33 U.S.C. section 1317), (b) defined as a "hazardous waste"
pursuant to Section 1004 of the Federal Research Conservation and Recovery Act,
42 U.S.C. section 6901 et seq. (42 U.S.C. section 6903) or (c) defined as a
"hazardous substance" pursuant to Section 101 of the Comprehensive Environmental
Response, Compensation and Liability Act, 42 U.S.C. section 9601 et seq. (42
U.S.C. section 9601).

         3. If Sublessee shall breach any obligation stated in this Article, or
if the presence of any Hazardous Material on the Premises caused or permitted by
Sublessee results in contamination of the Premises, or if contamination of the
Premises by Hazardous Material otherwise occurs for which Sublessee is legally
liable to Landlord or Sublessor for damage resulting therefrom, then Sublessee
shall indemnify, defend, and hold harmless Landlord and Sublessor from any and
all claims, judgments, damages, penalties, fines, costs, liabilities or losses
(including, without limitation, diminution in value of the Premises, damages for
the loss or restriction on use of rentable or useable space or any amenity of
the Premises, damages arising from any adverse impact on marketing of space, and
amounts paid in settlement of claims, attorneys' fees, consultants' fees and
expert fees) which arise during or after the Sublease Term as a result of such
contamination. This indemnification of Landlord and Sublessor by Sublessee
includes, without limitation, costs and expenses incurred in connection with any
investigation of site conditions or any clean-up, remedial, removal or
restoration work required by any federal, state or local governmental agency or
political subdivision because of Hazardous Material present in the soil or
groundwater on or under the Premises. Without limiting the foregoing, if the
presence of any Hazardous Material, in, on or about the Premises caused or
permitted by Sublessee results in any contamination of the Premises, then
Sublessee promptly shall take all actions at its sole cost and expense as are
necessary to put the Premises in such a condition that the Premises comply with
all applicable governmental standards, regulations, rules or ordinances;
provided that the approval of Landlord and Sublessor for such actions shall
first be obtained.

         4. In the event Sublessee shall install any electrical equipment that
overloads the lines in the Premises, Sublessee shall, at its sole expense, make
whatever changes are necessary to comply with the requirements of the insurance
underwriters and governmental authorities having jurisdiction thereof.

                      COVENANTS OF SUBLESSOR AND SUBLESSEE
                      ------------------------------------

         1. So long as Sublessee timely pays the rental due hereunder and
performs and observes all of the covenants and provisions contained herein and
in the Lease required to be performed and observed by Sublessee, Sublessor shall
not interfere with Sublessee's enjoyment and peaceful possession of the Premises
throughout the Sublease Term.

         2. Pursuant to Section 5.A. of the Lease, during the Sublease Term,
Sublessee shall be solely responsible for providing and paying for the upkeep of
the Premises and all appliances and fixtures installed therein, and all of the
mechanical, electrical and plumbing systems pertaining thereto, including, but
not limited to, those items set forth in Section 5.A. (i) through (viii)
inclusive of the Lease, to the same extent as if Sublessee were the tenant under
the Lease.

         3. Pursuant to Section 5.B. of the Lease, during the Sublease Term,
Sublessee shall be solely responsible for the payment of all items of
"Additional Rent" as defined and provided in Section 5.B. of the Lease,
including, but not limited to, the payment of all "Taxes", "Insurance" and
"Operating Costs" all as defined and provided in Section 5.B. (i) through (iii)
inclusive of the Lease, to the same extent as if Sublessee were the tenant under
the Lease.

   
         4. Pursuant to Section 7.A. of the Lease, during the Sublease Term,
Sublessee shall be solely responsible for carrying and keeping in full force and
effect those insurance policies required to be carried by Sublessor pursuant to
Section 7.A. of the Lease, to the same extent as if Sublessee were the tenant
under the Lease. Sublessee shall not be entitled to self-insure against any
casualties required to be insured against pursuant to Section 7 of the Lease.
During the Sublease Term, such insurance policies shall include Landlord,
Sublessor, and Bay Networks, Inc. as additional insured parties thereunder, as
their interests may appear. Prior to occupying the Premises, Sublessee shall
deliver to Landlord and Sublessor certificates of insurance reasonably
acceptable to Sublessor and Landlord evidencing that the insurance required
under Section 7.A. of the Lease to be secured by Sublessor (and therefore by
Sublessee hereunder) is in full force and effect.
    

         5. Pursuant to Section 10 of the Lease, during the Sublease Term,
Sublessee shall be solely responsible for all maintenance and repair obligations
set forth in Section 10 of the Lease in accordance with and as specified in
Section 5 of the Lease, to the same extent as if Sublessee were the tenant under
the Lease.

         6. In addition to the provisions of Section 11 of the Lease governing
the making of any alterations, modifications or improvements to the Premises
("Alterations") by Sublessor, Sublessee shall not undertake any such
alterations, modifications or improvements to the Premises without the prior
written consent of Sublessor, which consent shall not be unreasonably withheld
or delayed.

         7. Wherever in the Lease Sublessor, as tenant thereunder, is required
to pay to Landlord thereunder, certain pass-through expenses, costs, fees, etc.
in addition to the basic rent provided therein, to the extent that such
pass-through expenses, costs, fees, etc. are not specifically dealt with and
provided for in this Sublease, during the Sublease Term Sublessee agrees, on
demand, to pay promptly when due, all of such pass-through expenses, costs,
fees, etc.

         8. Except as otherwise expressly provided in this Sublease, Sublessee
agrees to perform, abide and be bound by all of the terms, covenants,
obligations, provisions, conditions, indemnities and waivers and exemptions
contained in the Lease with respect to the Premises to the same extent as if
Sublessee were the tenant under the Lease, and all terms, covenants,
obligations, provisions, conditions, indemnities, waivers and exemptions
contained and made in the Lease for the benefit of Landlord thereunder, shall be
deemed made by Sublessee hereunder and to inure to the benefit of both Sublessor
and Landlord hereunder and thereunder.

                             SUBLESSEE'S INDEMNITIES
                             -----------------------

         1. In addition to any other indemnities of Sublessee set forth
elsewhere in this Sublease, Sublessee shall indemnify, defend and save harmless
Sublessor and Landlord from and against any and all claims, actions, demands,
damages, liabilities and expenses, including reasonable attorneys' and other
professional fees, arising from or related to, wholly or in part, directly or
indirectly, any failure of Sublessee to observe or perform any of the terms,
covenants, obligations and conditions of the Lease and/or this Sublease required
to be observed or performed by Sublessee.

         2. Sublessee shall indemnify, defend and hold harmless Landlord and
Sublessor from and against any and all claims of any kind or nature arising from
Sublessee's use and occupancy of the Premises, including, without limitation,
claims arising out of or from damage to persons and property, claims arising out
of or from Sublessee's merchandise and inventory, any damage or injury to
Sublessee's employees, agents or invitees, or any damage or injury to any third
persons arising out of the conduct of such employees, agents, or invitees, and
Sublessee hereby waives all claims against Landlord and Sublessor and their
respective officers, agents, employees, partners, directors and shareholders for
loss of or damage to, goods, wares or merchandise or for injuries to persons in
and about the Premises from any cause whatsoever.

Sublessor, which consent may be withheld by Sublessor for any reason whatsoever.

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

         Should the Premises be taken by condemnation or under any right of
eminent domain, Sublessor shall be entitled to terminate this Sublease effective
as of the date on which Sublessee is forced to relinquish possession of the
Premises or on the date on which the Lease terminates as a result of such
taking, as the case may be. Sublessee shall have no right to claim or receive
any damages or any portion of any award with respect to such condemnation.

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

         Sublessor hereby agrees that Sublessee, upon the payment of all rent as
required hereunder and upon the performance of all covenants and terms of this
Sublease, may quietly hold and enjoy the Premises, free from hindrance by
Sublessor, but subject, however, to the Lease and any mortgages, liens,
restrictions, conditions, covenants or other encumbrances now or hereafter
affecting the Premises.


                                   ARTICLE XII
                                   -----------
                        SUBLESSOR'S REMEDIES UPON DEFAULT
                        ---------------------------------

         1. If Sublessee defaults in the performance of any of the covenants,
terms, conditions or provisions of this Sublease and Sublessee fails to cure
such default within ten (10) days after written notice thereof from Sublessor
(or fails to cure such default with due diligence if the default is of such a
nature as to require more than ten (10) days to cure), then Sublessor may, at
its option (but shall not be required to do so), perform the same for the
account of Sublessee and any amounts paid or expenses incurred by Sublessor in
the performance thereof, together with interest computed at the rate of ten
percent (10%) per annum, shall be deemed additional rent and due and payable to
Sublessor on demand. The receipt by Sublessor of any installment of any rentals
hereunder shall not be deemed a waiver of any other rentals or other amounts
then due.

         2. If Sublessee defaults in the payment of the rentals reserved
hereunder, or any part thereof, or in making any other payment herein provided,
and any such default shall continue for a period of ten (10) days after the same
is due and payable; or if the Premises or any part thereof shall be abandoned or
if Sublessee shall be dispossessed therefrom by or under any authority other
than Sublessor; or if Sublessee shall file a voluntary petition in bankruptcy or
if Sublessee shall file any petition or institute any proceeding under any
insolvency or bankruptcy law (or any amendment or addition thereto hereafter
made) seeking to effect its reorganization or a composition with its creditors
or if Sublessee shall make a general assignment for the benefit of creditors, or
if (in any proceedings based on the insolvency of Sublessee or relating to
bankruptcy proceedings) a receiver or trustee shall be appointed for Sublessee
or the Premises, or if any


                                        7

<PAGE>   8



proceedings shall be commenced for the reorganization of Sublessee under any
insolvency or bankruptcy law, or if the leasehold estate created hereby shall be
taken on execution or by any process of law, or if Sublessee shall admit in
writing its inability to pay its obligations generally as they become due, then
Sublessor may, at its option, terminate this Sublease without notice, but
Sublessee shall remain liable to Sublessor for the full amount of all rentals or
other amounts due hereunder.

         3. If Sublessee defaults in the fulfillment of any of the covenants or
conditions of this Sublease, other than the covenants for the payment of rent
(unless the result of such default is herein otherwise expressly provided for),
Sublessor may, at its option, terminate this Sublease by giving Sublessee thirty
(30) days notice of such termination in writing and thereupon at the expiration
of such thirty (30) days, this Sublease shall expire as fully and completely as
if that day were the date definitely set for the expiration of the Sublease Term
and Sublessee shall then quit and surrender the Premises, but Sublessee shall
remain liable to Sublessor for the full amount of all rentals and other amounts
due hereunder; provided, however, that if Sublessee shall, within the period of
thirty (30) days set forth in such notice, fully cure such default and furnish
Sublessor with proof or evidence satisfactory to Sublessor of such cure, then
and in that event such notice shall thereupon become null and void and this
Sublease shall continue in full force and effect without impairment.

         4. After termination of this Sublease, Sublessor or Sublessor's agents
may immediately, or at any time thereafter, reenter the Premises and remove all
persons and property therefrom (by legal proceedings or by force or otherwise)
without being liable to indictment, prosecution or damages therefor. In the
event that Sublessor shall obtain possession of the Premises, Sublessee agrees
to pay to Sublessor, on demand, an amount equal to the expenses incurred by
Sublessor in obtaining possession, including court costs and attorneys' fees,
and such other expenses as Sublessor may reasonably incur in putting the
Premises in good order and condition, and Sublessee shall remain liable to
Sublessor for the full amount of all rentals and other amounts due hereunder.
Such reentry, repossession and removal by Landlord shall not be a waiver,
release or discharge of any obligation or liability of Sublessee hereunder.

         5. All of the rights, remedies and benefits reserved by and conferred
upon Sublessor in this Article and at law or in equity are and shall be
cumulative.

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

         Sublessor reserves the right, at all times, to subject and subordinate
Sublessee's rights under the Sublease to Landlord's or Sublessor's interest in
the Premises or to any lien now or hereafter placed on such interests in the
Premises. Sublessee shall execute within ten (10) days of request, any
certificate that Landlord, Sublessor or any of their respective successors in
interest or assigns may reasonably request.

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 _____ 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 also an officer or key
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 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:

                           (a) 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.

                           (b) 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.

                           (c) 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 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. 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. 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.

         12. 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.

         13. 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 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

                                       -7-

<PAGE>   8



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.

         14. 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
Options 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 28OG of the Code.

         15. 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.

         16. TAXES.

                  16.1 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.

                  16.2 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.

         17. 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.

         18. 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.

         19. 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 to an Option.

         20. 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.

         21. 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.

         22. OTHER PROVISIONS. As used in the Plan, and in Options 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

                                       -9-

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

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

members at a meeting duly called and held. The Committee shall make such rules
and regulations for the conduct of its business as it shall deem advisable and
shall appoint a Secretary who shall keep minutes of its meetings and records of
all action taken in writing without a meeting. No member of the Committee shall
be liable, in the absence of bad faith, for any act or omission with respect to
his or her service on the Committee.

         5. GRANT OF OPTIONS. Each Director who is a Director on the date the
Plan becomes effective shall be granted an Option on such date to purchase
25,000 Shares without further action by the Board or the Committee. Each
Director who joins the Board after the date the Plan becomes effective shall be
granted an Option on the first day of his initial term on the Board to purchase
25,000 Shares without further action by the Board or the Committee. In addition,
on the fifth business day after the Company's Annual Report on Form 10-K is
filed with the Securities and Exchange Commission for each fiscal year during
which the Plan is in effect, each Director who is a Director on such date shall
be automatically granted an additional Option to purchase 5,000 Shares without
further action by the Board or the Committee. If the number of Shares available
under the Plan on a scheduled grant date is insufficient to make all automatic
grants required to be made pursuant to the Plan on such date, then each eligible
Director shall receive an Option to purchase a pro rata number of the remaining
Shares, if any, under the Plan; provided further, however, that if such
proration results in fractional Shares, then such Option shall be rounded down
to the nearest number of whole Shares.

         6. BASIC STOCK OPTION PROVISIONS.

                  6.1 OPTION PRICE. The option price per share of any 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.

                  6.2 TERM OF OPTIONS. Subject to paragraphs (a) and (b) of this
         Section 6.2, Options granted hereunder shall be exercisable for a Term
         of ten (10) years from the date of grant thereof, but shall be subject
         to earlier termination as hereinafter provided.

                           (a) Except as otherwise provided in the Plan, prior
                  to its expiration or termination, any Option granted hereunder
                  on the date the Plan becomes effective or on the first day of
                  a Director's initial term on the Board (each, an "Initial
                  Option") may be exercised within the following time
                  limitations:

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

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

                                    (iii) After three years from the date of the
                           grant, an Initial Option may be exercised as to any
                           part or all of the Shares originally subject to the
                           Initial Option.

                           (b) Except as otherwise provided in the Plan, prior
                  to its expiration or termination, any Option granted hereunder
                  that is not an Initial Option may be exercised at any time
                  after three years from the date of grant.

                  6.3 TERMINATION OF DIRECTORSHIP. In the event a Director
         ceases to be a member of the Board (other than by reason of death or
         disability), then (a) an Option may be exercised by the Director (to
         the extent the Director shall have been entitled to do so at the time
         he or she ceased to be a member of the Board) at any time within seven
         (7) months after he or she ceases to be a member of the Board, but not
         beyond the Term of the Option and (b) the portion of the Option that
         has not vested as of the date the Director ceases to be a member of the
         Board shall automatically terminate.

                  6.4 DEATH OR DISABILITY OF DIRECTOR. If a Director dies or
         becomes disabled while he or she is a member of the Board, or within
         seven (7) months after he or she ceases to be a Member of the Board, an
         Option may be exercised (to the extent the Director was entitled to do
         so at the time of his or her death or disability) by the Director or
         the Director's Successor, as the case may be, at any time within one
         (1) year after the Director ceases to be a member of the Board on
         account of such death or disability, but not beyond the Term of the
         Option.

7. EXERCISE OF RIGHTS UNDER AWARDS.

                  7.1 NOTICE OF EXERCISE. A Director entitled to exercise an
         Option may 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 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 the
         Shares to be purchased based on their 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 Chief Financial Officer, or such other person as the
         Committee may designate. No fractional Shares shall be issued.


                                                         5

<PAGE>   6



                  7.2 CASHLESS EXERCISE PROCEDURES. The Company, in its sole
         discretion, may establish procedures whereby a Director, 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 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.

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

         9. 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 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.

         10. NONTRANSFERABILITY OF OPTIONS. An Option shall not be transferable,
other than: (a) by will or the laws of descent and distribution, and an Option
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.

         11. 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 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.

         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

                                        6

<PAGE>   7



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 this Plan shall be a condition precedent to the exercise of any Option.

         14. TAXES.

                  14.1 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, 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.

         15. TERMINATION OF THE PLAN. The Plan shall terminate ten (10) years
from the date the Plan becomes effective, and an Option shall not be granted
under the Plan after that date although the terms of any Option may be amended
at any date prior to the end of its Term in accordance with the Plan. Any Option
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.

         16. AMENDMENT OF THE PLAN. The Plan may be amended at any time and from
time to time by the Board. 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.

         17. DELIVERY OF SHARES ON EXERCISE. Delivery of certificates for Shares
pursuant to an Option exercise 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 a Director

                                        7

<PAGE>   8


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.

         18. 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.

         19. EFFECTIVENESS OF THE PLAN. The Plan was approved by the Board and
the Company's sole stockholder, Penril DataComm Networks, Inc., on
_______________, 1996, and shall become effective on _______________, 1996.

         20. 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

                                   FORM OF
                         TRANSITIONAL SERVICES AGREEMENT
                         -------------------------------
    

         This Transitional Services Agreement (the "Agreement") is entered into
as of _____________, 1996, by and between PENRIL DATACOMM NETWORKS, INC.
("Parent") and ACCESS BEYOND, INC., a Delaware corporation ("A/B").

         WHEREAS, Parent owns 100% of the issued and outstanding shares of
common stock of A/B ("A/B Common Stock");

         WHEREAS, Parent will distribute to the holders of its common stock
("Parent Stockholders") all of the A/B Common Stock owned by Parent on a pro
rata basis and without consideration being paid by such holders (the
"Distribution");

   
         WHEREAS, after the Distribution, Parent and A/B will be separate
companies with a subsidiary of Bay Networks, Inc. ("Bay") to be merged with and
into Parent ("Merger"); and
    

         WHEREAS, to facilitate Parent's ongoing business, Parent and A/B desire
to enter into this Agreement to set forth the terms upon which A/B will provide
services to Parent for a one-year period following the Distribution.

   
         NOW, THEREFORE, in consideration of the mutual covenants contained
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

         1. SERVICES. The parties agree that A/B will provide to Parent the
following services for a period of one (1) year following the Distribution: (i)
assistance in the preparation of federal, state, local and foreign tax returns
and assistance with respect to federal, state and local compliance for income,
franchise, sales and use taxes, tax planning and audit negotiation and support,

assistance in the preparation for shipping
    



<PAGE>   2
   

of certain equipment and inventories and (iv) the administrative, clerical
and operational services set forth on Exhibit A (the "Services"). The Services
will be  provided at such times and with respect to such matters as Parent may 
reasonably request from time to time.
    

         2. SERVICES FEE. As compensation for the Services rendered under this
Agreement, Parent will pay to A/B, upon execution of this Agreement, the sum of
$1,500,000 ("Fee"). The Fee is intended to cover the costs incurred by A/B in
providing the Services, including salary and other administrative costs and
expenses (but excluding payments to third parties).

   
         3. REIMBURSEMENT OF EXPENSES. To the extent that A/B pays any expense
allocable to Parent to a third party for reasons of administrative convenience
(a "Reimbursable Expense"), A/B will promptly bill Parent for the amount
thereof, and Parent will reimburse A/B within thirty (30) days of receipt of
such invoice. Notwithstanding the foregoing, A/B will not make any payment in an
amount equal to or greater than Five Thousand Dollars ($5,000), or equal to or
greater than Five Thousand Dollars ($5,000.00) in the aggregate for any single
person or entity, without the prior written approval of Parent.

         4. LIABILITY AND INDEMNIFICATION. A/B will be liable in connection 
with this agreement to Parent or to any third party in privity with, connected
or affiliated with Parent, only if A/B has engaged in conduct in connection
with providing the Services which constitute willful misconduct. A/B will be
fully protected in any action taken in good faith in accordance with advice of
legal counsel. A/B will be fully protected in acting in accordance with any
written instructions given to it hereunder and reasonably believed by it to
have been executed by Parent.
    

         5. WAIVER. Failure of either party to enforce any provision or
provisions of this Agreement will not in any way be construed as a waiver of any
such provision as to any future violations, nor prevent that party from 
enforcing every other provision of this Agreement. The

                                        2


<PAGE>   3


rights granted to the parties in this Agreement are cumulative and the waiver 
of any single remedy will not constitute a waiver of such party's right to 
assert all other legal remedies available to it under the circumstances.

   
         6. COOPERATION. Each party to this Agreement agrees to cooperate with
the other party in good faith to carry out the purpose and intent of this
Agreement. Each party shall afford the other and its counsel, accountants and
agent reasonable access during normal working hours to all books, records,
contracts, instruments, computer data and other information relating to affairs
of the respective businesses before the date hereof ("Information") as is
reasonably requested, provided, however, neither A/B nor Parent shall be 
required to divulge Information which it believes will cause it any 
competitive disadvantage.
    

         7. SEVERABLE PROVISIONS. The provisions of this Agreement are
severable, and if any one or more provisions are determined to be illegal or
otherwise unenforceable, in whole or in part, the remaining provisions and any
partially enforceable provision will be binding and enforceable to the extent
enforceable in any jurisdiction.

   
         8. ASSIGNMENT. Except in connection with the Merger, neither A/B nor 
Parent may assign any of its rights or benefits under this Agreement without
the prior written consent of the other, which consent will not be unreasonably
withheld or delayed. This Agreement is binding on and will inure to the benefit
of the parties and their respective successors and permitted assignees.
    

         9. NO THIRD PARTY BENEFICIARIES. This Agreement is solely for the
benefit of the parties hereto and should not be deemed to confer upon third
parties any remedy, claim, liability, reimbursement, claim of action, or other 
right in excess of those existing without reference to this Agreement.
