Item 5. Other Events.

      On July 29, 1997, Access Beyond, Inc. (the "Registrant"), entered into an
Agreement and Plan of Reorganization (the "Agreement") with Hayes Microcomputer
Products, Inc., a Georgia corporation ("Hayes"). Pursuant to the terms of the
Agreement, the Registrant will form a wholly-owned Georgia subsidiary that will
merge with and into Hayes (the "Merger"). As a result, Hayes will become a
wholly-owned subsidiary of the Registrant. The Merger is subject to, among other
things, satisfactory completion of due diligence by both parties, the
Registrant's obtaining a fairness opinion, compliance with the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, the filing and effectiveness of
the Registrant's Registration Statement on Form S-4, and approval of the
transaction by the requisite shareholders of Hayes and the Registrant.

      When the Merger becomes effective, (a) the Hayes shareholders (excluding
holders of options and warrants) will own 79% of the total outstanding equity of
the Registrant (excluding options), subject to adjustment if Hayes or the
Registrant issue additional equity securities prior to the Merger becoming
effective; (b) the Registrant will assume all outstanding options and warrants
held by Hayes stockholders to purchase Hayes stock; (c) the Registrant will
change its name to Hayes Communications Inc.; and (d) the Board of Directors of
the Registrant will be increased to seven, with three of the Registrant's
present five directors resigning.

                      AGREEMENT AND PLAN OF REORGANIZATION

      This Agreement and Plan of Reorganization (this "Agreement") is entered
into as of July 29, 1997, by and between Access Beyond, Inc., a Delaware
corporation ("Access Beyond"), and Hayes Microcomputer Products, Inc., a Georgia
corporation ("Hayes") (and individually referred to as "Party" and jointly and
severally referred to herein as "Parties").

      A. The Parties intend that, subject to the terms and conditions set forth
herein, a new corporation that will be organized in Georgia as a wholly owned
subsidiary of Access Beyond ("Newco") will merge with and into Hayes in a
reverse triangular merger (the "Merger"), with Hayes to be the surviving
corporation of the Merger, all pursuant to the terms and conditions of this
Agreement and Certificate of Merger substantially in the form of Exhibit A (the
"Certificate of Merger") and the applicable provisions of the laws of Georgia.

      B. Upon the effectiveness of the Merger, all the outstanding capital stock
of Hayes will be converted into capital stock of Access Beyond, and Access
Beyond will assume all outstanding options and warrants to purchase shares of
Hayes capital stock, in the manner and on the basis determined herein and as
provided in the Certificate of Merger.

      C. The Merger is intended to be treated as a "purchase" for accounting
purposes and a tax-free reorganization pursuant to the provisions of Section
368(a)(1)(A) of the Internal Revenue Code of 1986, as amended (the "Code"), by
virtue of the provisions of Section 368(a)(2)(E) of the Code.

      D.    Concurrent with the execution and delivery of this Agreement:

            (i) Dennis C. Hayes, Chestnut Capital, LLC, Rinzai Limited and
Vulcan Ventures Incorporated, who together hold a majority or more of the issued
and outstanding shares of each class or series of Hayes capital stock, and a
sufficient number of shares of Hayes capital stock to approve the Merger (the
"Principal Hayes Shareholders"), are each executing and delivering to Access
Beyond a fully signed copy of a certain Voting Agreement substantially in the
form of Exhibit C-1 containing a market standoff agreement, an agreement to vote
in favor of the Merger, this Agreement, the Certificate of Merger and the
transactions provided for herein and against any transaction that could
adversely affect the Merger (collectively, the "Voting Agreements");

            (ii) certain other shareholders of Hayes are entering into a "Market
Standoff Agreement" in substantially the form attached hereto as Exhibit C-2;

            (iii) the Principal Hayes Shareholders and any other shareholder of
Hayes who is an "affiliate" of Hayes within the meaning of Rule 145 promulgated
by the Securities and Exchange Commission under the Securities Act of 1933, as
amended, and the key corporate officers and directors of Hayes by the end of the
Due Diligence Period will be entering into the "Hayes Affiliates Agreements"
substantially in the form of Exhibit C-3 hereto;
<PAGE>

            (iv) the shareholders of Hayes and Ronald A. Howard are entering
into a Shareholders' Agreement to be effective at the Effective Time (the
"Shareholders' Agreement"); and

            (v) Ronald A. Howard and Dennis C. Hayes are entering into an
Employment Agreement or an amendment to Employment Agreement with Access Beyond
substantially in the form of Exhibits C-4 and C-5 hereto, respectively (the
"Employment Agreements").

      The Parties acknowledge that in the event that the transactions
contemplated by this Agreement are not consummated, each Party 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 Merger, including but not limited to, a
condition that there shall be no material adverse change prior to the Effective
Time (as defined below) to either Party, its business, financial condition,
results of operations or prospects, or to either Party's industry or to general
business conditions.

      Now, therefore, in reliance upon the recitals set forth above, the Parties
hereto agree as follows:

      I. PLAN OF REORGANIZATION.

            1.1 The Merger. Subject to the terms and conditions of this
Agreement, prior to the Closing Date (as defined in Section 6.1 below), Access
Beyond will incorporate and organize Newco and will cause the Board of Directors
and shareholders of Newco to approve the Merger and become a party to this
Agreement which is obligated to perform all of the duties of Newco set forth in
this Agreement. Subject to the terms and conditions of this Agreement, the
Certificate of Merger will be filed with the Secretary of State of the State of
Georgia on the Closing Date. The date and time that the Certificate of Merger is
filed with the Georgia Secretary of State and the Merger thereby becomes
effective will be referred to in this Agreement as the "Effective Time." Subject
to the terms and conditions of this Agreement and the Certificate of Merger,
Newco will be merged with and into Hayes in a statutory merger pursuant to the
Certificate of Merger and in accordance with applicable provisions of Georgia
law as follows.

                  1.1.1 Creation of Series A Stock. Prior to the Effective Time,
Access Beyond will have amended its Certificate of Incorporation to create the
Series A Preferred Stock of Access Beyond (the "Access Beyond Series A Stock"),
each share of which shall initially be convertible into one share of Access
Beyond Common Stock, $0.01 par value ("Access Beyond Common Stock") and shall
have the rights, preferences, privileges and restrictions as are specified in
the form of Restated Certificate of Incorporation attached hereto as Exhibit
7.13.

                  1.1.2 Conversion of Hayes Common Stock. Each share of Hayes
Common Stock, $0.01 par value (the "Hayes Common Stock") that is issued and
outstanding immediately


                                       2
<PAGE>

prior to the Effective Time (other than shares, if any, for which dissenters
rights are perfected in compliance with applicable law), will, by virtue of the
Merger and at the Effective Time and without further action on the part of any
holder thereof, be converted into the right to receive that number of fully paid
and nonassessable shares of Access Beyond Common Stock, that is equal to the
Conversion Ratio.

                  1.1.3 Conversion of Hayes Series A Stock. Each share of Hayes
Series A Preferred Stock, no par value (the "Hayes Series A Stock"), that is
issued and outstanding immediately prior to the Effective Time (other than
shares, if any, for which dissenters rights are perfected in compliance with
applicable law), will, by virtue of the Merger and at the Effective Time and
without further action on the part of any holder thereof, be converted into the
right to receive that number of fully paid and nonassessable shares of Access
Beyond Common Stock that is equal to the Conversion Ratio multiplied by the
number of shares of Hayes Common Stock into which such share of Hayes Series A
Stock is then convertible.

                  1.1.4 Conversion of Hayes Series B Stock. Each share of Hayes
Series B Preferred Stock, no par value (the "Hayes Series B Stock"), that is
issued and outstanding immediately prior to the Effective Time (other than
shares, if any, for which dissenters rights are perfected in compliance with
applicable law), will, by virtue of the Merger and at the Effective Time and
without further action on the part of any holder thereof, be converted into the
right to receive that number of fully paid and nonassessable shares of Access
Beyond Series A Stock that is equal to the Conversion Ratio multiplied by the
number of shares of Hayes Common Stock into which such share of Hayes Series B
Stock is then convertible.

                  1.1.5 Conversion Ratio Defined. For purposes of this
Agreement, the "Conversion Ratio" shall be determined as follows,

First, take the percentage ownership immediately after Closing of the issued and
outstanding shares of Access Beyond Common Stock and Access Beyond Series A
Stock that the holders of all classes of Hayes Common, Series A Preferred Stock
and Series B Preferred Stock in the aggregate are entitled to receive as a
result of and immediately following the Merger, which the Parties hereby agree
is seventy-nine percent (79%) (the "Hayes Percentage").

Next, calculate the "Conversion Ratio" according to the following formula:

              Conversion Ratio = [ B ( {C} OVER {1.0 - B} ) ] / D

Where:      B   = .79 (the "Hayes Percentage")


                                       3
<PAGE>

            C   = The number of shares of Access Beyond common and preferred
                  stock issued and outstanding on a fully diluted basis
                  (excluding all issued and outstanding Access Beyond stock
                  options) immediately prior to the Effective Time

            D   = The number of shares of Hayes common and preferred stock
                  issued and outstanding on a fully diluted basis immediately
                  prior to the Effective Time, excluding all issued and
                  outstanding Hayes stock options and warrants in accordance
                  with Sections 2.4.2 and 5.4 hereof

Thus, for example only, assuming that the number of fully diluted shares of
Access Beyond common and preferred stock (excluding shares issuable upon
exercise of Access Beyond stock options) outstanding immediately prior to the
Effective Time, or "C," equals 12,500,000 and that the number of fully diluted
shares of Hayes common and preferred stock outstanding (excluding shares
issuable upon exercise of Hayes stock options and warrants) immediately prior to
the Effective Time, or "D," equals 10,000,000, then the Conversion Ratio would
be 4.702381.


                  1.1.6 Dissenting Shares. Holders of Hayes Common Stock, Hayes
Series A Stock and/or Hayes Series B Stock (the "Hayes Stock") who have complied
with all requirements for perfecting shareholders' rights of appraisal, if any,
as set forth in Section 14-2-1301 et seq. of the Georgia Business Corporation
Code ("Georgia Law"), shall be entitled to their rights under the Georgia Law,
if any, with respect to such shares ("Dissenting Shares") and not to any portion
of the Access Beyond Common Stock or Access Beyond Series A Stock receivable by
the shareholders of Hayes by reason of the Merger.

                  1.1.7 Conversion of Newco Shares. Each share of Newco Common
Stock, par value $0.01 ("Newco Common Stock"), that is issued and outstanding
immediately prior to the Effective Time will, by virtue of the Merger and
without further action on the part of the sole shareholder of Newco, be
converted into and become one share of Hayes Common Stock that is to be issued
and outstanding immediately after the Effective Time, and the share of Hayes
Common Stock into which the shares of Newco Common Stock are so converted shall
be the only share of Hayes Stock that is issued and outstanding immediately
after the Effective Time.

            1.2 Fractional Shares. No fractional shares of Access Beyond Common
Stock or Access Beyond Series A Stock (the "Access Beyond Stock") will be issued
in connection with the Merger, but in lieu thereof, the record holder of any
shares of Hayes Stock who would otherwise be entitled to receive a fraction of a
share of Access Beyond Stock, upon aggregation of all shares and fractional
shares owned by such holder, will receive from Access Beyond, promptly after the
Effective Time, without interest, an amount of cash equal to the per share
market value of Access Beyond Stock (based on the closing sale price of Access
Beyond Common Stock on the last trading day prior to the Closing Date, as quoted
on the Nasdaq National Market and reported in the Western Edition of The Wall
Street Journal) multiplied by the fraction of a share of Access Beyond Stock to
which such holder would otherwise be entitled.

            1.3 Hayes Options and Warrants.

                  1.3.1 Assumption of Options and Warrants. At the Effective
Time, each outstanding option (collectively, the "Hayes Options") to purchase
Hayes Common Stock granted under Hayes' Stock Option Plan, as amended (the
"Hayes Plan"), and each warrant for the purchase of Hayes Stock (the "Hayes
Warrants") shall be assumed by Access Beyond in accordance with the terms of
such option or warrant, and converted into rights with respect to that number of
shares of Access Beyond Common Stock, determined by multiplying the number of
shares of Hayes Stock subject to such Hayes Option or Hayes Warrant (on an as if
exercised basis) immediately prior to the Effective Time by the Conversion
Ratio, and the exercise price per share for each such option or warrant will
equal the exercise price of the Hayes Option or the Hayes Warrant immediately
prior to the Effective Time divided by the Conversion Ratio (rounded up to the
nearest whole cent). If the foregoing calculation results in an assumed option
or warrant being exercisable for a fraction of a share, then the number of
shares of Access Beyond Common Stock subject to such option or warrant will be
rounded down to the nearest whole number with no cash being payable for such
fractional share.

                  1.3.2 Terms of Assumed Options and Warrants. Access Beyond
will administer the Hayes Plan assumed pursuant to this Section 1.3 in a manner
that complies with Rule 16b-3 promulgated by the SEC under the Securities
Exchange Act of 1934 ("Exchange Act"). Continuous employment with Hayes will be
credited to an optionee for purposes of determining the number of shares subject
to exercise after the Effective Time. The term, exercisability, vesting
schedule, status as an "incentive stock option" under Section 422 of the Code,
if applicable, and all other terms of the Hayes Options and Hayes Warrants will
otherwise be unchanged. Access Beyond will cause the Access Beyond Common Stock
issued upon exercise of the assumed Hayes Options and Hayes Warrants (to the
extent that such Hayes Warrants were issued in a compensatory transaction and
are otherwise eligible to be registered on Form S-8) together with the Access
Beyond stock option plans in effect after the Effective Time, to the extent same
qualify for such registration and have not previously been registered, to be
registered on Form S-8 of the Securities and Exchange Commission ("SEC") within
90 days after the Effective Time, will exercise reasonably diligent efforts to
maintain the effectiveness of such registration statement for so long as such
assumed Hayes Options and such eligible Hayes Warrants remain outstanding and
will reserve a sufficient number of shares of Access Beyond Common Stock for
issuance upon exercise of the assumed Hayes Options and Hayes Warrants.

            1.4 Effects of the Merger. At the Effective Time: (a) the separate
existence of Newco will cease and Newco will be merged with and into Hayes and
Hayes will be the surviving corporation pursuant to the terms of the Certificate
of Merger; (b) the Articles of Incorporation and Bylaws of Hayes will remain the
Articles of Incorporation and Bylaws of the surviving corporation; (c) each
share of Newco Common Stock outstanding immediately prior to the Effective Time
will be converted into one outstanding share of Hayes Common Stock; (d) the
directors of Hayes to be in effect subsequent to the Effective Time will be the
directors of Hayes as the surviving corporation and the officers of Hayes will
remain the officers of Hayes as the


                                       5
<PAGE>

surviving corporation; (e) each share of Hayes Stock and each Hayes Option and
Hayes Warrant outstanding immediately prior to the Effective Time will be
converted as provided in Section 1.1, 1.2 and 1.3; and (f) the Merger will, at
and after the Effective Time, have all of the effects provided by applicable
law.

            1.5 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)(A) of the Code. The Parties
believe that the value of the Access Beyond Stock to be received in the Merger
is equal, in each instance, to the value of the Hayes Stock to be surrendered in
exchange therefor. The Access Beyond Stock issued in the Merger will be issued
solely in exchange for the Hayes Stock, and no other transaction other than the
Merger represents, provides for or is intended to be an adjustment to, the
consideration paid for the Hayes Stock. Except for cash paid in lieu of
fractional shares or for Dissenting Shares, no consideration that could
constitute "other property" within the meaning of Section 356 of the Code is
being paid by Access Beyond for the Hayes Stock in the Merger. The Parties shall
not take a position on any tax returns inconsistent with this Section 1.5. In
addition, Access Beyond represents now, and as of the Closing, that it presently
intends to continue Hayes' historic business or use a significant portion of
Hayes' business assets in a business. At the Closing, officers of each of Access
Beyond and Hayes shall execute and deliver officers' certificates in the forms
of Exhibits 1.5A-B. The provisions and representations contained or referred to
in this Section 1.5 shall survive until the expiration of the applicable statute
of limitations.

            1.6 Purchase Accounting Treatment. The Parties intend that the
Merger be treated as a "purchase" for accounting purposes.

            1.7 Charter Amendments. Contemporaneously with or immediately prior
to the Closing, the name of Access Beyond will be changed to "Hayes
Communications Inc.", and the Amended and Restated Certificate of Incorporation
of Access Beyond attached hereto as Exhibit 7.13 will become effective,
accomplishing inter alia, the creation of the Access Beyond Series A Stock.

      2. REPRESENTATIONS AND WARRANTIES OF HAYES.

            Except as set forth in the Hayes disclosure letter (the "Hayes
Disclosure Letter") a draft of which was delivered by Hayes on July 28, 1997, to

corporation duly organized, validly existing and in good standing under the laws
of the State of its formation, has the corporate power and authority to own,

            2.3 Power, Authorization and Validity.

                  2.3.1 Organization. Hayes has the corporate right, power,
legal capacity and authority to enter into and perform its obligations under
this Agreement, and all agreements to which Hayes or its shareholders are or
will be parties that are required to be executed pursuant to this Agreement.
This Agreement has been duly and validly approved by the Hayes Board of
Directors and, upon submission to, and majority vote in favor of the Merger by
the Hayes shareholders, by the Hayes shareholders, as required by applicable

contemplated hereby and (e) the filings required by the HSR Act (defined in
Section 4.6).

                  2.3.3 Enforceability. This Agreement, the Hayes Affiliate
Agreements, the Voting Agreement and the Market Standoff Agreements are, or when
executed and delivered by Hayes and the other parties thereto will be, valid and
binding obligations of Hayes and, as applicable, the Principal Hayes

                                       7
<PAGE>

parties thereto enforceable against such persons or entities in accordance with
their respective terms, except as to the effect, if any, of (a) applicable
bankruptcy and other similar laws affecting the rights of creditors generally
and (b) rules of law governing specific performance, injunctive relief and other
equitable remedies.

            2.4 Capitalization.

                  2.4.1 Capital Stock. The authorized capital stock of Hayes
consists of 100,000,000 shares of Hayes Common Stock, $0.01 par value per share,
10,000,000 shares of Hayes Series A Stock and 263,113 shares of Hayes Series B
Stock. 4,991,750 shares of Hayes Common Stock, 4,900,000 shares of Hayes Series
A Stock and 263,113 shares of Hayes Series B Stock are issued or outstanding as
of the date of this Agreement and will be immediately prior to the Closing, all
of which are held of record and owned by the Hayes shareholders identified in
Item 2.4. Except as set forth in the Hayes Amended and Restated Articles of
Incorporation, each share of Hayes Series A Stock and each share of Hayes Series
B Stock is convertible into one share of Hayes Common Stock. None of the
outstanding Hayes Stock carries any mandatory redemption rights, other than the
Hayes Series B Preferred Stock. All issued and outstanding shares of Hayes Stock
have been duly authorized and validly issued, are fully paid and nonassessable,
are not subject to any right of rescission and have been offered, issued, sold
and delivered by Hayes in compliance with all registration or qualification
requirements (or applicable exemptions therefrom) of applicable federal and
state securities laws.

                  2.4.2 Options/Warrants/Rights. As of the date hereof, 400,000
shares of Hayes Common Stock are subject to issued and outstanding warrants to
purchase shares of Hayes Common Stock. As of the date hereof, an aggregate of
1,800,000 shares of Hayes Common Stock are reserved and authorized for issuance
pursuant to the Hayes Plan, of which options to purchase a total of 1,414,750
shares of Hayes Common Stock are issued and outstanding. Also, shares of Hayes
Common Stock are reserved and authorized for issuance pursuant to conversion of
the Notes described in Section 5.3.1 of this Agreement, which notes constitute
all issued and outstanding debt that is convertible into any shares of Hayes
Stock. A list of all holders of Hayes Stock and options or warrants to purchase
Hayes Stock as of the date hereof, and the number of shares, options and
warrants held by each has been delivered by Hayes to Access Beyond as Item 2.4,
which will be updated at the Closing. Except as set forth in this Section, there
are no options, warrants, calls, commitments, conversion privileges or
preemptive or other rights or agreements outstanding to purchase any of Hayes',
or any of the Hayes Subsidiaries' authorized but unissued capital stock or any
securities convertible into or exchangeable for shares of Hayes Stock or the
securities of any Hayes Subsidiary or obligating Hayes or any such Hayes
Subsidiary to grant, extend, or enter into any such option, warrant, call,
right, commitment, conversion privilege or other right or agreement, and there
is no liability for dividends accrued but unpaid. There are no voting
agreements, rights of first refusal or other restrictions (other than normal
restrictions on transfer under applicable federal and state securities laws)
applicable to any of Hayes' or any Hayes Subsidiaries' outstanding securities.
Neither Hayes nor any Hayes Subsidiary is under any


                                       8
<PAGE>

obligation to register under the Securities Act of 1933, as amended (the
"Securities Act") any of its presently outstanding securities or any securities
that may be subsequently issued.

            2.5 No Conflict or Violation. Neither the execution and delivery of
this Agreement nor the consummation of the transactions provided for herein,
will conflict with, or (with or without notice or lapse of time, or both) result
in a termination, breach, impairment or violation of, (a) any provision of the
Articles of Incorporation or Bylaws of Hayes, as currently in effect, (b) any
material instrument or contract to which Hayes or any Hayes Subsidiary is a
Party or by which Hayes or any Hayes Subsidiary is bound (including, without
limitation, the Hayes Material Agreements described in Section 2.11) or (c) any
federal, state, local or foreign judgment, writ, decree, order, statute, rule or
regulation applicable to, and that would have a material adverse effect on,
Hayes or any Hayes Subsidiary or any of their assets or properties. The
consummation of the Merger in and of itself will not require the consent of any
third party, will not have a material adverse effect upon any such rights,
licenses, franchises, leases or agreements pursuant to the terms of the Hayes
Material Agreements and will not be affected by, or require compliance with,
Section 14-2-1111 of the Georgia Law.

            2.6 Litigation. There is no action, proceeding or investigation
pending or, to Hayes' actual knowledge, threatened against Hayes or any Hayes
Subsidiary before any court or administrative agency that, if determined
adversely to Hayes or such subsidiary, may reasonably be expected to have a
material adverse effect on the present or future operations or financial
condition of Hayes or, except as set forth in Item 2.6, in which the adverse
party or parties seek to recover in excess of $200,000 against Hayes or such
subsidiary. Except as set forth in Item 2.6, there is no basis for any person,
firm, corporation or entity to assert a claim against Hayes, any Hayes
Subsidiary or Access Beyond as the sole shareholder of Hayes immediately
following the Closing based upon: (a) ownership or rights to ownership of any
shares of Hayes Stock or Hayes Subsidiary capital stock, (b) any rights as a
Hayes or Hayes Subsidiary securities holder, including, without limitation, any
option or other right to acquire any Hayes or Hayes Subsidiary securities, any
preemptive rights or any rights to notice or to vote or (c) any rights under any
agreement between Hayes or any Hayes Subsidiary and any Hayes or Hayes
Subsidiary securities holder or former securities holder in such holder's
capacity as such.

            2.7 Hayes Financial Statements. Hayes has delivered to Access Beyond
Hayes' audited consolidated balance sheet as of December 31, 1996 (the "Hayes
Balance Sheet Date") and a consolidated income statement and statement of cash
flows for the year then ended, and Hayes' consolidated unaudited balance sheet,
income statement and cash flow statement for the period from January 1, 1997
through June 30, 1997 (collectively, the "Hayes Financial Statements"). The
Hayes Financial Statements, in all material respects, (a) are in accordance with
the books and records of Hayes, (b) fairly and accurately present the financial
condition of Hayes and its subsidiaries at the respective dates specified
therein and the results of operations for the respective periods specified
therein and (c) except as may be indicated in the notes thereto, were prepared
in accordance with generally accepted accounting principles consistently applied
(subject in the case of unaudited financial statements to normal, year-end audit
adjustments and the absence of


                                       9
<PAGE>

footnotes) ("GAAP"). Hayes and the Hayes Subsidiaries have no material debt,
liability or obligation of any nature, whether accrued, absolute, contingent or
otherwise, and whether due or to become due, that is not reflected, reserved
against or disclosed in the Hayes Financial Statements, except for those that
may have been incurred after the Hayes Balance Sheet Date in the ordinary course
of business, or are not required to be included in a balance sheet prepared in
accordance with GAAP. The inventories of Hayes and the Hayes Subsidiaries are of
quality and quantity usable or salable in the ordinary course of business, the
aggregate value of which has been written down on the books of said corporations
to realizable market value or with respect to which adequate reserves have been
provided in accordance with GAAP.

            2.8 Taxes. Hayes and the Hayes Subsidiaries have filed all federal,
state, local and foreign tax and material information returns required to be
filed prior to the date hereof, have paid all taxes required to be paid in
respect of all periods prior to the date hereof for which returns have been
filed, have made all necessary estimated tax payments, and have no liability for
taxes in excess of the amount so paid, except to the extent adequate reserves
have been established in the Hayes Financial Statements. True and complete
copies of all such tax and information returns have been provided or made
available by Hayes to Access Beyond. Neither Hayes nor any Hayes Subsidiary is
delinquent in the payment of any tax or in the filing of any tax returns, and no
deficiencies for any tax have been threatened, claimed, proposed or assessed
which have not been settled or paid. No tax return of Hayes or any Hayes
Subsidiary has been audited by the Internal Revenue Service or any state taxing
agency or authority during the past seven fiscal years or the current fiscal
year. For the purposes of this Section 2.8 and Section 3.8. the terms "tax" and
"taxes" include all federal, state, local and foreign income, gains, franchise,
excise, property, sales, use, employment, license, payroll. occupation,
recording, value added or transfer taxes, governmental charges, fees, levies or
assessments (whether payable directly or by withholding), and, with respect to
such taxes, any estimated tax, interest and penalties or additions to tax and
interest on such penalties and additions to tax. Hayes has no current or
deferred federal income tax liabilities on a consolidated basis, and will not as
a result of the Merger become liable for any income tax not adequately reserved
against on the Financial Statements. Neither Hayes nor any Hayes Subsidiary has
filed a consent pursuant to Section 341(f) of the Code.

            2.9 Title to Properties. Hayes and each Hayes Subsidiary has good
and marketable title to all of its assets as shown on the balance sheet as of
the Hayes Balance Sheet Date included in the Hayes Financial Statements, free
and clear of all liens, charges or encumbrances (other than for taxes not yet
due and payable and Hayes Permitted Liens as defined below), other than such
assets as were sold by Hayes in the ordinary course of business since the Hayes
Balance Sheet Date or which are subject to capitalized leases. "Hayes Permitted
Liens" means any lien, mortgage, encumbrance or restriction which is reflected
in the Hayes Financial Statements and is not in excess of $50,000 and which does
not materially detract from the value or materially interfere with the use, as
currently utilized, of the properties subject thereto or affected thereby or
otherwise materially impair the business operations being conducted thereon.
There are no UCC financing statements of record with the State of Georgia, or
any other State where Hayes and each Hayes Subsidiary owns or leases property,
naming Hayes and each Hayes


                                       10
<PAGE>

Subsidiary as debtor. The machinery and equipment included in such assets are,
in all material respects, in good condition and repair, normal wear and tear
excepted. All leases of real or personal property to which Hayes and each Hayes
Subsidiary is a party are fully effective and afford Hayes and each Hayes
Subsidiary adequate possession of the subject matter of the lease. To its
knowledge, neither Hayes nor any Hayes Subsidiary is in violation of any
material zoning, building, safety or environmental ordinance, regulation or
requirement or other law or regulation applicable to the operation of owned or
leased properties, and Hayes and each Hayes Subsidiary has not received any
notice of such violation with which it has not complied or had waived.

            2.10 Absence of Certain Changes. Since the Hayes Balance Sheet Date,
Hayes and the Hayes Subsidiaries have carried on their business in the ordinary
course substantially in accordance with the procedures and practices in effect
on the Hayes Balance Sheet Date, and there has not been with respect to Hayes
and the Hayes Subsidiaries:

                  (a) any contingent liability incurred by Hayes or any Hayes
      Subsidiary as guarantor or surety with respect to the obligations of
      others;

                  (b) any mortgage, encumbrance or lien placed on any of the
      properties of Hayes or any Hayes Subsidiary, other than liens for taxes
      not yet due and payable and Hayes Permitted Liens;

                  (c) any material obligation or liability incurred by Hayes or
      any Hayes Subsidiary other than in the ordinary course of business;

                  (d) any purchase or sale or other disposition, or any
      agreement or other arrangement for the purchase, sale or other
      disposition, of any of the properties or assets of Hayes or any Hayes
      Subsidiary other than in the ordinary course of business or in amounts
      that are not material to Hayes and the Hayes Subsidiaries or their
      businesses considered as a whole;

                  (e) any damage, destruction or loss, whether or not covered by
      insurance, materially and adversely affecting the properties or business
      of Hayes and the Hayes Subsidiaries or their businesses considered as a
      whole;

                  (f) any declaration, setting aside or payment of any dividend
      on, or the making of any other distribution in respect of, the capital
      stock of Hayes, any split, stock dividend, combination or recapitalization
      of the capital stock of Hayes or any direct or indirect redemption,
      purchase or other acquisition by Hayes of any Hayes Stock;

                  (g) any unresolved labor dispute or claim of material unfair
      employment or labor practices, any change in the compensation payable, or
      to become payable, to any of Hayes' or of any Hayes Subsidiaries'
      officers, employees or agents earning compensation at an anticipated
      annual rate in excess of $50,000, or any bonus payment or


                                       11
<PAGE>

      arrangement made to or with any of such officers, employees or agents; or
      any change in the compensation payable or to become payable to any of
      Hayes' or of any Hayes Subsidiaries' other officers, employees or agents
      other than normal annual raises and bonuses in accordance with past
      practice;

                  (h) any change with respect to the senior management or other
      key personnel of Hayes (each of whom is listed in Item 2.15) or of any
      Hayes Subsidiary, except as contemplated by this Agreement and its
      Exhibits;

                  (i) any payment or discharge of a material lien or liability
      thereof, which lien or liability was not either (i) shown on the balance
      sheet as of the Hayes Balance Sheet Date included in the Hayes Financial
      Statements or (ii) incurred in the ordinary course of business after the
      Hayes Balance Sheet Date;

                  (j) any obligation or liability incurred by Hayes or any Hayes
      Subsidiary to any of their officers, directors or shareholders, or any
      loans or advances made to any of their officers, directors. shareholders
      or affiliates, except normal compensation and expense allowances payable
      to officers; or

                  (k) any material deterioration in the relationship of Hayes or
      any of the Hayes Subsidiaries with any customer or supplier, which would
      have a material adverse effect on the businesses of Hayes and the Hayes
      Subsidiaries, taken as a whole.

            2.11 Agreements and Commitments. A list of oral or written executory
agreements, obligations or commitments that are material to Hayes, any Hayes
Subsidiary or their businesses, taken as a whole (the "Hayes Material
Agreements"), is included as Item 2.11, true and complete copies of which have
been or will be delivered to Access Beyond or Access Beyond's counsel. Each
Hayes Material Agreement is valid and in full force and effect. Neither Hayes
nor, to the knowledge of Hayes, any other party, is in breach of, or default
under, any material term of any such Hayes Material Agreement. Except for the
Hayes Material Agreements, neither Hayes nor any Hayes Subsidiary is a party or
subject to any oral or written executory agreement, obligation or commitment
that is material to Hayes, any Hayes Subsidiary or their businesses, taken as a
whole, that is not terminable within 60 days without cost or penalty to Hayes or
any Hayes Subsidiary, including but not limited to the following:

                  2.15.5 Conduct of Hayes Employee Plans. All contributions due
from Hayes or any Hayes Subsidiary with respect to any of the Hayes Employee
Plans have been made or accrued on Hayes' financial statements, and no further

Each of the Hayes Employee Plans, and its operation and administration, is, in
all material respects, in compliance with all applicable, federal, state, local
and other governmental laws and ordinances, orders, rules and regulations,
including the requirements of ERISA and the Code. All such Hayes Employee Plans
that are "employee pension benefit plans" (as defined in Section 3(2) of ERISA)
which are intended to qualify under Section 401(a)(8) of the Code have received
favorable determination letters that such plans satisfy the qualification
requirements of the Tax Equity and Fiscal Responsibility Act of 1982, the
Deficit Reduction Act of 1984 and the Retirement Equity Act of 1984. In
addition, neither Hayes nor any Hayes Subsidiary has been a participant in any
"prohibited transaction," within the meaning of Section 406 of ERISA with
respect to any employee pension benefit plan (as defined in Section 3(2) of
ERISA) which Hayes or any Hayes Subsidiary sponsors as employer or in which
Hayes or any Hayes Subsidiary participates as an employer, which was not
otherwise exempt pursuant to Section 408 of ERISA (including any individual
exemption granted under Section 408(a) of ERISA), or which could result in an
excise tax under the Code. The group health plans, as defined in Section
4980B(g) of the Code, that benefit employees of Hayes or any Hayes Subsidiaries
are in material compliance with the continuation coverage requirements of
subsection 4980B of the Code. There are no outstanding violations of Section
4980B of the Code with respect to any Hayes Employee Plan, covered employees or
qualified beneficiaries.

                  2.15.6 Effect of Agreement. Neither Hayes nor any Hayes
Subsidiary is a party to any agreement with any executive officer or other key
employee (a) the benefits of which are contingent, or the terms of which are
materially altered, upon the occurrence of a transaction involving Hayes in the
nature of any of the transactions contemplated by this Agreement, (b) providing
any term of employment or compensation guarantee or (c) providing severance
benefits or other benefits after the termination of employment of such employee.
Neither Hayes nor any Hayes Subsidiary is a party to any agreement or plan,
including, without limitation, any stock option plan, stock appreciation rights
plan or stock purchase plan, (a) any of the benefits of which will be materially
increased, or the vesting of benefits of which will be materially accelerated,
by the occurrence of any of the transactions contemplated by this Agreement or
(b) the value of any of the benefits of which will be calculated on the basis of
any of the transactions contemplated by this Agreement, except for the vesting
of certain exercisability rights under the Hayes Warrant Plan and the Hayes
Stock Option Plan, and except as described on Exhibit C-5 hereto. Neither Hayes
nor any Hayes Subsidiary is obligated to make any excess parachute payment, as
defined in Section 280G(b)(1) of the Code, nor will any excess parachute payment
be deemed to have occurred as a result of or arising out of the Merger to the
extent Section 280G of the Code is applicable to Hayes or any Hayes Subsidiary.

Beyond for examination all documents and information listed in the Hayes
Disclosure Letter that are requested by Access Beyond's legal counsel,

threatened releases of Hazardous Materials on or from any of such premises,
which may have occurred prior to Hayes or any Hayes Subsidiary having taken
possession of any of such premises that would have a material adverse effect
upon Hayes, any Hayes Subsidiary or any of their businesses. For purposes of

Compensation and Liability Act of 1980, 42 U.S.C. ss. 9601 et seq., as amended
("CERCLA"). For the purposes of this Agreement, "Hazardous Materials" mean any
hazardous or toxic substance, material or waste which is or becomes prior to the
Closing Date (as defined in Section 6.1 hereof) regulated under, or defined as a
"hazardous substance," "pollutant," "contaminant," "toxic chemical," "hazardous

claim or dispute involving Hayes, any Hayes Subsidiary and any Government
Contract Party or (b) any suspension, debarment. contract renegotiation, or
contract termination, or proceeding related thereto. There has been no act or
omission that relates to the marketing, licensing or selling to any Government
Contract Party of any of Hayes' or any Hayes Subsidiary's technical data and
computer software and that has led to or could lead to, either before or after
the Closing, any material cloud on any of Hayes' or any Hayes Subsidiary's
rights in and to its technical data and computer software. All of Hayes' and the
Hayes Subsidiaries' development of technical data and computer software was
developed exclusively at private expense. For purposes of this Agreement, the
term "Government Contract Party" means any independent or executive agency,
division, subdivision, audit group or procuring office of the federal
government, including any prime contractor of the federal government and any
higher level subcontractor of a prime contractor of the federal government, and
including any employees or agents thereof, in each case acting in such capacity.

            2.21 No Brokers. Neither Hayes or any of the Hayes Subsidiaries is
obligated for the payment of fees or expenses of any investment banker, broker

Agreement or in connection with any transaction provided for herein.

Subsidiary before any court or administrative agency that, if determined
adversely to Access Beyond or such subsidiary, may reasonably be expected to
have a material adverse effect on the present or future operations or financial
condition of Access Beyond or, except as set forth in Item 3.6, in which the
adverse party or parties seek to recover in excess of $100,000.00 against Access
Beyond or such subsidiary. There is no basis for any person, firm, corporation
or entity to assert a claim against Access Beyond or any Access Beyond
Subsidiary based upon: (a) ownership or rights to ownership of any shares of
Access Beyond Stock or Access Beyond Subsidiary capital stock, (b) any rights as
an Access Beyond or Access Beyond Subsidiary securities holder, including,
without limitation, any option or other right to acquire any Access Beyond or
Access Beyond Subsidiary securities, any preemptive rights or any rights to
notice or to vote or (c) any rights under any agreement between Access Beyond or
any Access Beyond Subsidiary and any Access Beyond or Access Beyond Subsidiary
securities holder or former securities holder in such holder's capacity as such.

            3.7 Access Beyond Financial Statements. Access Beyond has delivered
to Hayes Access Beyond's audited consolidated balance sheet as of July 31, 1996
(the "Access Beyond Balance Sheet Date") and a consolidated income statement and
statement of cash flows for the year then ended, and Access Beyond's
consolidated unaudited balance sheet, income statement and cash flow statement
for the period from August 1, 1996 through April 30, 1997 (collectively, the
"Access Beyond Financial Statements"). The Access Beyond Financial Statements,
in all material respects, (a) are in accordance with the books and records of
Access Beyond, (b) fairly and accurately present the financial condition of
Access Beyond and its subsidiaries at the respective dates specified therein and
(c) except as may be indicated in the notes thereto, were prepared in accordance
with GAAP. Access Beyond and Access Beyond Subsidiaries have no material debt,
liability or obligation of any nature, whether accrued, absolute, contingent or
otherwise, and whether due or to become due, that is not reflected, reserved
against or disclosed in the Access Beyond Financial Statements, except for those
that may have been incurred after the Access Beyond Balance Sheet Date in the
ordinary course of business, or are not required to be included in a balance
sheet prepared in accordance with GAAP. The inventories of Access Beyond and the
Access Beyond Subsidiaries are of a quality and quantity usable or salable in
the ordinary course of business, the aggregate value of which has been
written-down on the books of said corporations to realizable market value or
with respect to which adequate reserves have been provided in accordance with
GAAP.

            3.8 Taxes. Access Beyond and the Access Beyond Subsidiaries have
filed all federal, state, local and foreign tax and material information returns
required to be filed prior to the date hereof, have paid all taxes required to
be paid in respect of all periods prior to the date hereof for which returns
have been filed, have made all necessary estimated tax payments, and have no
liability for taxes in excess of the amount so paid, except to the extent
adequate reserves have been established in the Access Beyond Financial
Statements. True and complete copies of all such tax and information returns
have been provided or made available by Access Beyond to Hayes. Neither Access
Beyond nor any Access Beyond Subsidiary is delinquent in the payment of any tax
or in the filing of any tax returns, and no deficiencies for any tax have been
threatened,


                                       22
<PAGE>

claimed, proposed or assessed which have not been settled or paid. -No tax
return of Access Beyond or any Access Beyond Subsidiary has been audited by the
Internal Revenue Service or any state taxing agency or authority during the past
seven fiscal years or the current fiscal year. For the purposes of this Section
3.8, the terms "tax" and "taxes" shall have the meanings given to those terms in
Section 2.8. Access Beyond has no current or deferred federal income tax
liabilities on a consolidated basis, and will not as a result of the Merger
become liable for any income tax not adequately reserved against on the
Financial Statements. Neither Access Beyond nor any Access Beyond Subsidiary has
filed a consent pursuant to Section 341(f) of the Code.

            3.9 Title to Properties. Access Beyond has good and marketable title
to all of its assets as shown on the balance sheet as of the Access Beyond
Balance Sheet Date included in the Access Beyond Financial Statements, free and
clear of all liens, charges or encumbrances (other than for taxes not yet due
and payable and Access Beyond Permitted Liens as defined below), other than such
assets as were sold by Access Beyond in the ordinary course of business since
the Access Beyond Balance Sheet Date or which are subject to capitalized leases.
"Access Beyond Permitted Liens" means any lien, mortgage, encumbrance or
restriction which is reflected in the Access Beyond Financial Statements and is
not in excess of $50,000 and which does not materially detract from the value or
materially interfere with the use, as currently utilized, of the properties
subject thereto or affected thereby or otherwise materially impair the business
operations being conducted thereon. There are no UCC financing statements of
record with the State of Maryland naming Access Beyond as debtor and Access
Beyond neither owns or leases any property in any other state. The machinery and
equipment included in such assets are, in all material respects, in good
condition and repair, normal wear and tear excepted. All leases of real or
personal property to which Access Beyond is a party are fully effective and
afford Access Beyond adequate possession of the subject matter of the lease. To
its knowledge, Access Beyond is not in violation of any material zoning,
building, safety or environmental ordinance, regulation or requirement or other
law or regulation applicable to the operation of owned or leased properties, and
Access Beyond has not received any notice of such violation with which it has
not complied or had waived.

            3.10 Absence of Certain Changes. Since the Access Beyond Balance
Sheet Date, Access Beyond and the Access Beyond Subsidiaries have carried on
their business in the ordinary course substantially in accordance with the
procedures and practices in effect on the Access Beyond Balance Sheet Date, and

Subsidiaries:

      on, or the making of any other distribution in respect of, the capital
      stock of Access Beyond, any split, stock dividend, combination or
      recapitalization of the capital stock of Access Beyond or any direct or
      indirect redemption, purchase or other acquisition by Access Beyond of any
      Access Beyond Stock;

                  (g) any unresolved labor dispute or claim of material unfair
      employment or labor practices, any change in the compensation payable, or
      to become payable, to any of Access Beyond's or of any Access Beyond
      Subsidiaries' officers, employees or agents earning compensation at an
      anticipated annual rate in excess of $50,000, or any bonus payment or
      arrangement made to or with any of such officers, employees or agents; or
      any change in the compensation payable or to become payable to any of
      Access Beyond's or of any Access Beyond Subsidiaries' other officers,

      accordance with past practice, except for "stay-put" bonuses and severance
      pay arrangements which do not exceed $600,000 in the aggregate;

                  (h) any change, not in the ordinary course of business, with
      respect to the management, supervisory, development or other key personnel

      Beyond Subsidiary, except as contemplated by this Agreement and its
      Exhibits;

                  (i) any payment or discharge of a material lien or liability
      thereof, which lien or liability was not either (i) shown on the balance

      business after the Access Beyond Balance Sheet Date;

                  (j) any obligation or liability incurred by Access Beyond or

      affiliates, except normal compensation and expense allowances payable to
      officers; or

                  (k) any material deterioration in the relationship of Access
      Beyond or any of the Access Beyond Subsidiaries with any customer or

            4.10 Confidentiality and Disclosure. Neither Party shall, nor shall
permit any of its representatives to, issue any press release or otherwise
publicly disseminate any document or other written material relating to the
Merger or any of the other transactions contemplated by this Agreement unless
(a) each Party shall have approved such press release or written material (it
being understood that neither Party shall unreasonably withhold or delay its
approval of any such press release or written material), or (b) Access Beyond
shall have been advised by its outside legal counsel that the issuance of such
press release or the dissemination of such written material is required by any
applicable law or regulation, and Access Beyond shall have consulted with Hayes
and shall have used its best efforts to modify such release so that it is
reasonably acceptable to Hayes prior to issuing such press release or
disseminating such written material; provided, however, that Access Beyond shall
be entitled to file with the SEC, after the execution and delivery of this
Agreement, a report on Form 8-K (together with a copy of this Agreement
(including the exhibits hereto) and the press release (all of which shall have
been approved by Hayes) announcing this Agreement. Each Party shall use
reasonable, diligent efforts to ensure that none of its representatives makes
any public statement, whether oral or written, that is materially inconsistent
with any press release issued or any written material approved in advance by
Hayes and Access Beyond and publicly disseminated by Access Beyond or Hayes with
respect to the Merger or with respect to any of the other transactions
contemplated by this Agreement. Hayes will take all reasonable precautions to
prevent any trading in the securities of Access Beyond by officers, directors,
employees and agents of Hayes having knowledge of any material information
regarding Access Beyond provided hereunder, or any disclosure by any such
persons to anyone outside of Access Beyond or Hayes of any material non-public
information concerning Access Beyond, any Access Beyond Subsidiary or the
transactions contemplated by this Agreement, until the information in question
has been adequately and publicly disclosed.

            4.11 Affiliate Agreements. To ensure that the issuance of Access
Beyond Stock in the Merger complies with the Securities Act, concurrently with
the execution of this Agreement Hayes will deliver to Access Beyond a letter
identifying all persons who are, in Hayes' reasonable judgment, "affiliates" of
Hayes (for purposes of Rule 145 promulgated under the Securities Act)


                                      40
<PAGE>

at the time this Agreement is executed. Hayes will provide Access Beyond with
all information and documents needed to evaluate this list for compliance with
securities laws. Concurrent with the execution of this Agreement, Hayes will
cause each of its affiliates to deliver to Access Beyond, written agreements
(the "Hayes Affiliate Agreements") in the form of Exhibit C-3, providing, among
other things, that such persons will not offer to sell, sell or otherwise
dispose of any of the Access Beyond Stock issued to such person in the Merger in
violation of the Securities Act and Rule 145 promulgated thereunder, as they may
be amended from time to time, and will make no disposition of Access Beyond
Stock for certain periods of time after the Effective Time.

            4.12 New Capital Funding. Both Hayes and Access Beyond shall make
diligent efforts to obtain equity capital for Access Beyond or Hayes prior to or
after the Merger in the aggregate amount of up to $35.0 million. In the event
either Party is successful in obtaining such additional capital, then each Party
agrees that it will be proportionately diluted by the new stock required to be
issued or issuable to any new investor, and that the respective percentages of
the shares of Access Beyond to be held immediately after the Effective Time by
the Access Beyond and Hayes shareholders as contemplated by Section 1.1.5 shall
be appropriately adjusted to accommodate the dilution occasioned by the new
capital funding. No binding contract for such new capital funding prior to the
Effective Time shall be entered into without the consent of the other Party,
which shall not be unreasonably withheld. The Parties acknowledge that Hayes has
entered into a commitment letter with respect to the issuance of $30 million in
capital stock dated July 16, 1997, and agree that the consummation of the
transaction described therein and as approved by Access Beyond by letter of even
date herewith shall not be deemed a breach of any representation, warranty or
covenant herein on the part of Hayes.

            4.13 Other Actions Required. During the period from the date of this
Agreement until the Effective Time or earlier termination of this Agreement in
accordance herewith, each Party covenants to, and agrees with, the other to use
reasonable, diligent efforts to satisfy or cause to be satisfied all the
conditions precedent which are set forth in Section 7 or 8 as to such Party, as
the case may be, and to cause the transactions provided for in this Agreement to
be consummated, and, without limiting the generality of the foregoing, to use
reasonable, diligent efforts to obtain all consents and authorizations of third
parties and to make all filings with, and give all notices to, third parties
that may be necessary or reasonably required on its part in order to effect the
transactions provided for herein.

      5.    HAYES PRECLOSING COVENANTS.

            5.1 Business Plan. By the end of the Due Diligence Period, Hayes
will prepare a proposed "high level" business plan for the combination of the

and will be constructed in such a manner that indicates ongoing operating
profitability within the year following the Closing of the Merger, with
reasonable contingencies. The business plan may be modified following the
Closing.

Common Stock or amended to terminate the convertibility feature of the Notes and
to adjust the repayment (after Closing of the Merger) by Hayes or Access Beyond
of the Notes to occur only upon a determination of the Board of Access Beyond,
in the exercise of its fiduciary duties, that sufficient cash flow is available
to make such repayment, in whole or in part.

                  5.3.2 Antidilution Warrant. Termination of that certain
Warrant to Purchase Stock issued to Rinzai Limited by Hayes on April 16, 1996
(the "Antidilution Warrant") shall be executed at or prior to the expiration of
the Due Diligence Period, effective upon the Effective Time.

                  5.3.3 Preferred Stock. The Hayes Series A Stock and the Hayes

Series B Stock only, the terms of such stock shall be revised at or prior to the
Effective Time and be clarified to provide that the Merger shall not trigger any
liquidation rights or preference or any such rights shall have been waived.

            5.4 Hayes Stock Option Plan. Prior to the Effective Time, Hayes
shall not grant any more warrants or any more options to its employees under the

<PAGE>

Beyond (the "Closing Date"), which (subject to the satisfaction or waiver of the
conditions set forth in Sections 7 and 8) shall be no later than the 5th
business day after satisfaction of the latest to occur of the conditions set
forth in Sections 7.5 and 8.5 (effectiveness of the Form S-4), 7.7 and 8.6
(obtaining approvals under the HSR Act) and 7.6 and 8.7 (obtaining stockholder
approval). Prior to, or concurrently with, the Closing, the Certificate of
Merger and such officers' certificates or other documents as may be required to
effectuate the Merger will be filed in the office of the Georgia Secretary of
State and the Merger will thereby become effective.

            6.2   Exchange of Certificates.

                  6.2.1 Hayes Stock Converted. As of the Effective Time, all
shares of Hayes Stock that are outstanding immediately prior thereto will, by
virtue of the Merger and without further action, cease to exist, and all such
shares, except for Dissenting Shares, will be converted into the right to
receive from Access Beyond the number of shares and type of Access Beyond Stock
determined as set forth in Section 1 hereof. At and after the Effective Time,
each certificate representing outstanding shares of Hayes Stock, except for
Dissenting Shares, will represent the right to receive the number of shares of
Access Beyond Stock into which such shares of Hayes Stock have been converted,
and such shares of Access Beyond Stock will be registered in the name of the
holder of such certificate. Unless surrendered to Access Beyond for exchange at
the Closing, as soon as practicable after the Effective Time, each holder of
shares of Hayes Stock, except for holders of Dissenting Shares, will surrender
(a) the certificates for such shares (the "Hayes Certificates") to Access Beyond
for cancellation or (b) an affidavit of lost (or nonissued) certificate and
indemnity with respect to the same, in form reasonably satisfactory to Access
Beyond. Promptly following the Effective Time and receipt of the Hayes
Certificates, Access Beyond will cause its transfer agent to issue to each such
surrendering holder, certificate(s) for the number of shares of Access Beyond
Stock to which such holder is entitled pursuant to Section 1.1, subject to
Section 1.1.6 hereof, and Access Beyond will distribute any cash payable under
Section 1.2. After the Effective Time, there will be no further registration of
transfers of the shares of Hayes Stock on the stock transfer books of Hayes.

                  6.2.2 Certificates Not Tendered. Until Hayes Certificates
representing Hayes Stock outstanding prior to the Merger are surrendered
pursuant to Section 6.2.1 above, such certificates, except for certificates
representing Dissenting Shares, will be deemed, for all purposes, to evidence
solely the right to receive (a) the number and type of shares of Access Beyond
Stock into which such shares of Hayes Stock will have been converted and (b) if
applicable, cash in lieu of fractional shares.

            6.3 Assumption of Options and Warrants. Promptly after the Effective
Time, Access Beyond will notify in writing each holder of a Hayes Option or a
Hayes Warrant of the assumption of such Hayes Option or Hayes Warrant by Access
Beyond, and the number of shares of Access Beyond Stock that are then subject to
such option or warrant and the exercise price of such option or warrant, as
determined pursuant to Section 1 hereof.

                  (d) by either Access Beyond or Hayes if (i) any of the
      applicable Hayes Shareholders repudiate the Voting Agreements (Exhibit
      C-1) entered into by them, or if (ii) the Hayes Shareholders Meeting shall
      have been held and this Agreement and the Merger shall not have been

      not held within ten (10) business days after SEC clearance of Form S-4 as
      contemplated in Sections 7.5 and 8.5; provided, however, that (i) Access
      Beyond shall not be permitted to terminate this Agreement pursuant to this
      clause (d) if the failure of the Hayes shareholders to adopt and approve
      this Agreement and the Merger at the Hayes Shareholders Meeting is
      attributable to a failure on the part of Access Beyond to perform any
      material obligation required to have been performed by Access Beyond under
      this Agreement, or if the Voting Agreements have terminated in accordance
      with their terms prior to the Hayes Shareholders' Meeting and (ii) Hayes
      shall not be permitted to terminate this Agreement pursuant to this clause
      (d) if the failure of the Hayes shareholders to adopt and approve this

      required to have been performed by Hayes under this Agreement;

                  (e) by either Access Beyond or Hayes if (i) the Access Beyond

      Meeting to vote on the Agreement is not held within sixty (60) days after
      SEC clearance of Form S-4, as contemplated in Sections 7.5 and 8.5;
      provided, however, that (i) Hayes shall not be permitted to terminate this
      Agreement pursuant to this clause (e) if the failure of the Access Beyond
      stockholders to adopt and approve this Agreement and the Merger at the
      Access Beyond Stockholders Meeting is attributable to a failure on the
      part of Hayes to perform any material obligation required to have been
      performed by Hayes under this Agreement, (ii) Access Beyond shall not be
      permitted to terminate this Agreement pursuant to this clause (e) if the
      failure of the Access Beyond stockholders to adopt and approve this

      attributable to a failure on the part of Access Beyond to perform any
      material obligation required to have been performed by Access Beyond under

                  (f) by Access Beyond (at any time prior to the adoption and
      approval of this Agreement and the Merger by the Hayes shareholders by the
      vote required by law) if a "Triggering Event" with respect to Hayes as the
      "Triggering Party" shall have occurred. A "Triggering Event" shall have
      occurred if (i) the Board of Directors of one of the Parties hereto (the
      "Triggering Party") shall have failed to recommend, or shall for any
      reason have withdrawn or shall have amended or modified in a manner

      of this Agreement and the Merger by the Access Beyond stockholders by the
      vote required by law) if a Triggering Event with respect to Access Beyond
      as the Triggering Party shall have occurred;

                  (h) by Access Beyond if any of the Hayes' representations and
      warranties contained in this Agreement shall be or shall have become
      materially inaccurate, or if any of Hayes' material covenants contained in
      this Agreement shall have been breached in any material respect or failure
      of a condition set forth in Section 8 to be met, which is incapable of
      being cured or satisfied; provided, however, that if an inaccuracy in
      Hayes' representations and warranties or a breach of covenant by Hayes is
      curable by Hayes and Hayes is continuing to exercise reasonable efforts to
      cure such inaccuracy or breach, then Access Beyond may not terminate this
      Agreement under this Section 9.1(h) on account of such inaccuracy or
      breach; or

                  (i) by Hayes if any of Access Beyond's representations and
      warranties contained in this Agreement shall be materially inaccurate as

      listed in Section 7.2 shall have become materially inaccurate, or if any
      of Access Beyond's material covenants contained in this Agreement shall
      have been breached in any material respect or failure of a condition set
      forth in Section 7 to be met, which is incapable of being cured or
      satisfied; provided, however, that if any inaccuracy in Access Beyond's
      representations and warranties or a breach of a covenant by Access Beyond
      is curable by Access Beyond and Access Beyond is continuing to exercise
      reasonable efforts to cure such inaccuracy or breach, then Hayes may not
      terminate this Agreement under this Section 9.1 (i) on account of such
      inaccuracy or breach.

            9.2 Effect of Termination. In the event of the termination of this
Agreement as provided in Section 9.1, this Agreement shall be of no further
force or effect; provided, however, that (a) this Section 9.2, Section 9.3,
Section 10 and Section 11 shall survive the termination of this Agreement and
shall remain in full force and effect, and (b) the termination of this Agreement
shall not relieve any Party, from any liability for any breach of this Agreement
by such Party.

            9.3   Expenses; Termination Fees.

                  9.3.1 Allocation. Except as set forth in this Section 9.3,
each Party will bear its respective expenses and fees of its own accountants,
attorneys, investment bankers and other professionals incurred with respect to
this Agreement and the transactions contemplated hereby, whether or not the
Merger is consummated; provided, however, that Hayes and Access Beyond shall
share equally all fees and expenses, other than attorneys' fees, incurred in
connection with the printing and filing of the Form S-4 and the Prospectus/Proxy
Statement and any amendments or supplements thereto. Each Party shall promptly
reimburse its principal shareholders, stockholders, officers and directors for
amounts paid by them as filing fees to governmental agencies and other
reasonable and necessary expenses that are incurred by such persons to comply
with any consent or approval required to be obtained in order to perform this
Agreement.

                  9.3.2 Break-up Fee.

                  (a) If this Agreement is terminated by Access Beyond pursuant
      to Section 9.1(f) or by Hayes pursuant to Section 9.1(g), and the
      stockholders of Hayes or Access Beyond, respectively, fail to approve the
      Merger, then the non-terminating Party shall pay to the terminating Party,
      as nonrefundable liquidated damages, in cash upon the last to occur of the
      Triggering Events, the total out-of-pocket expenses of the terminating
      Party incurred in connection with the negotiation and performance of this
      Agreement, plus $200,000, provided, however, that the aggregate amount of
      such payment shall not exceed $500,000;

                  (b) In addition, if either Party publicly announces the
      entering into of an agreement relating to an Acquisition Transaction
      within six months after the date of termination pursuant to Section 9.1(f)
      or 9.1(g), then the nonrefundable liquidated damages described in Section
      9.3.2(a) shall increase to $2,000,000, with the additional amount to be
      paid in cash within three business days after the closing of such
      Acquisition Transaction. Such liquidated damages shall be the sole remedy
      of Hayes against Access Beyond for its termination under Section 9.1(g)
      and the sole remedy of Access Beyond against Hayes for its termination
      under Section 9.1(f);

                  (c) If this Agreement is terminated by Hayes pursuant to
      Section 7.1 of this Agreement as provided therein or by Access Beyond due
      to its failure to satisfy the


                                      52
<PAGE>

      condition set forth in Section 8.16, Access Beyond shall pay to Hayes a
      termination fee in the amount of Hayes' total out-of-pocket expenses
      incurred in connection with negotiation and performance of this Agreement,
      provided that the aggregate amount of such termination fee shall not
      exceed $250,000, whereupon this Agreement shall be of no further force or
      effect and such remedy shall be Hayes' sole remedy for termination
      pursuant to Section 7.1;

                  (d) If this Agreement is terminated by Access Beyond pursuant
      to Section 8.1 of this Agreement as provided therein other than for
      failure to obtain the required fairness opinion, Hayes shall pay to Access
      Beyond a termination fee in the amount of Access Beyond's total
      out-of-pocket expenses incurred in connection with negotiation and
      performance of this Agreement, provided that the aggregate amount of such
      termination fee shall not exceed $250,000, whereupon this Agreement shall
      be of no further force or effect and such remedy shall be Access Beyond's
      sole remedy for termination pursuant to Section 8.1; and

                  (e) If this Agreement is terminated by either Party pursuant
      to Section 9.1(d) as provided therein or is terminated by Hayes for
      failure of the condition set forth in Section 7.11 to be met, then Hayes
      shall pay Access Beyond a termination fee in the amount of $2,000,000, as
      nonrefundable liquidated damages. Such liquidated damages shall be the
      sole remedy of Access Beyond against Hayes in such event.

      10.   NO SURVIVAL OF REPRESENTATIONS.

      All representations and warranties of the Parties contained in this
Agreement will expire as of the Effective Time and be of no further force or
effect subsequent to such time. Except for the obligations of the Parties under
Section 11 below, the representations and warranties of the Parties contained in
this Agreement will terminate as of the termination of this Agreement in
accordance with Section 9.1, clauses (a), (b) or (c).

      11.   GENERAL PROVISIONS.

            11.1 Governing Law; Dispute Resolution. The internal laws of the
State of Delaware (irrespective of its choice of law principles) will govern the
validity of this Agreement, the construction of its terms, and the
interpretation and enforcement of the rights and duties of the Parties hereto.
Any dispute hereunder ("Dispute") shall be settled by arbitration in Dover,
Delaware, and, except as herein specifically stated, in accordance with the
commercial arbitration rules of the American Arbitration Association ("AAA
Rules") then in effect. However, in all events, these arbitration provisions
shall govern over any conflicting rules which may now or hereafter be contained
in the AAA Rules. Any judgment upon the award rendered by the arbitrator may be
entered in any court having jurisdiction over the subject matter thereof. The
arbitrator shall have the authority to grant any equitable and legal remedies
that would be available in any judicial proceeding instituted to resolve a
Dispute.


                                      53
<PAGE>

                  11.1.1 Compensation of Arbitrator. Any such arbitration will
be conducted before a single arbitrator who will be compensated for his or her
services at a rate to be determined by the Parties or, if the Parties are unable
to agree, by the American Arbitration Association (the "AAA").

                  11.1.2 Selection of Arbitrator. The AAA will have the
authority to select an arbitrator from a list of five arbitrators who are
lawyers familiar with Delaware contract law; provided, however, that such
lawyers cannot work for a firm then performing services for either Party, that
each Party will have the opportunity to make such reasonable objection to any
two of the arbitrators listed as such Party may desire and that the AAA will
select the arbitrator from the list of arbitrators as to whom neither Party
makes any such objection.

                  11.1.3 Payment of Costs. Access Beyond and, before the
Closing, Hayes, will bear the expense of deposits and advances required by the
arbitrator in equal proportions, but either Party may advance such amounts,
subject to recovery as an addition or offset to any award. The arbitrator will
award to the prevailing Party, as determined by the arbitrator, all costs, fees
and expenses related to the arbitration, including reasonable fees and expenses
of attorneys, accountants and other professionals that were incurred by the
prevailing Party.

                  11.1.4 Burden of Proof. For any Dispute submitted to
arbitration, the burden of proof will be as it would be if the claim were
litigated in a judicial proceeding.

                  11.1.5 Award. Upon the conclusion of any arbitration
proceedings hereunder, the arbitrator will render findings of fact and
conclusions of law and a written opinion setting forth the basis and reasons for
any decision reached and will deliver such documents to each Party to this
Agreement along with a signed copy of the award.

                  11.1.6 Terms of Arbitration. The arbitrator chosen in
accordance with these provisions will not have the power to alter, amend or
otherwise affect the terms of these arbitration provisions.

                  11.1.7 Exclusive Remedy. Except as specifically otherwise
provided in this Agreement, arbitration will be the sole and exclusive remedy of
the Parties for any Dispute arising out of this Agreement.

            11.2 Assignment; Binding Upon Successors and Assigns. None of the
Parties hereto may assign any of its or his rights or obligations hereunder
without the prior written consent of the other Parties hereto. This Agreement
will be binding upon and inure to the benefit of the Parties hereto and their
respective successors and permitted assigns.

            11.3 Severability. If any provision of this Agreement, or the
application thereof, is for any reason held to any extent to be invalid or
unenforceable, the remainder of this Agreement and application of such provision
to other persons or circumstances will be interpreted


                                      54
<PAGE>

so as reasonably to effect the intent of the Parties hereto. The Parties further
agree to replace such unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of the void or unenforceable provision.

            11.4 Counterparts. This Agreement may be executed in counterparts,
each of which will be an original as regards any Party whose name appears
thereon and all of which together will constitute one and the same agreement.
This Agreement will become binding when one or more counterparts hereof,
individually or taken together, bear the signatures of all Parties reflected
hereon as signatories.

            11.5 Other Remedies. Except as otherwise provided herein, any and
all remedies herein expressly conferred upon a Party will be deemed cumulative
with and not exclusive of any other remedy conferred hereby or by law on such
Party, and the exercise of any one remedy will not preclude the exercise of any
other.

            11.6 Amendment and Waivers. Any term or provision of this Agreement
may be amended, and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively), only by a writing signed by the Parties to be bound thereby. The
waiver by a Party of any breach hereof or default in the performance hereof will
not be deemed to constitute a waiver of any other default or any succeeding
breach or default. This Agreement may be amended by the Parties hereto at any
time before or after approval of the Hayes or Access Beyond shareholders or
stockholders, respectively.

            11.7 No Waiver. The failure of any Party to enforce any of the
provisions hereof will not be construed to be a waiver of the right of such
Party thereafter to enforce such provisions. The waiver by any Party of the
right to enforce any of the provisions hereof on any occasion will not be
construed to be a waiver of the right of such Party to enforce such provision on
any other occasion.

            11.8 Notices. All notices, requests, demands and other
communications required or permitted hereunder shall be in writing and by any
one or more of the following means: (i) if mailed by prepaid first class mail or
certified mail, return receipt requested, at any time other than during a

      This Market Stand-Off Agreement (this "Agreement") is entered into as of
____________, 1997 by Access Beyond, Inc., Inc., a Delaware corporation ("Access

which provides (subject to the conditions set forth therein) for the merger of a
wholly owned subsidiary of Access Beyond ("Newco") with and into Hayes in a
reverse triangular merger (the "Merger"), with Hayes to be the surviving
corporation of the Merger. Capitalized terms used but not otherwise defined in
this Agreement have the meanings ascribed to such term in the Merger Agreement.

      B. As of the date hereof, Shareholder owns in the aggregate (including
shares held both beneficially and of record and other shares held either
beneficially or of record) the number of shares of the Common Stock, the Series
A Preferred Stock and the Series B Preferred Stock of Hayes set forth below
Shareholder's name on the signature page hereof (all such shares, together with
any shares of the Common Stock, the Series A Preferred Stock, the Series B
Preferred Stock or other shares of capital stock of Hayes that may hereafter be
acquired by Shareholder, being referred to herein as the "Subject Shares").

      C. As a condition to closing the Merger and other transactions
contemplated by the Merger Agreement, Access Beyond has required that
Shareholder agree to enter into this Agreement.

      Now, therefore, the parties to this Agreement, intending to be legally
bound, agree as follows:

grant of any option to purchase or other disposition or transfer of) any of the
Access Beyond Securities (as defined below) to any Person, (ii) create or permit
to exist any encumbrance on any of the Access Beyond Securities or (iii) reduce
its beneficial ownership of, interest in, or risk relating to, any of the Access
Beyond Securities. As used in this Agreement, the term "Access Beyond

Shareholder in the Merger or otherwise acquired or held by Shareholder.

2.    MISCELLANEOUS

Agreement and Plan of Reorganization dated as of July 29, 1997 between Access
Beyond and Hayes (as such may be amended the "Merger Agreement") which provides
(subject to the conditions set forth therein) for the merger of a wholly owned
subsidiary of Access Beyond ("Newco") with and into Hayes in a reverse
triangular merger (the "Merger"), with Hayes to be the surviving corporation of
the Merger, all pursuant to the terms and conditions of the Merger Agreement and
the Agreement of Merger to be entered into between Newco and Hayes in the form
attached to the Merger Agreement (the "Agreement of Merger"). The Merger
Agreement and the Agreement of Merger are collectively referred to herein as the
"Merger Agreements." Capitalized terms used but not otherwise defined in this
Affiliate Agreement have the meanings ascribed to such terms in the Merger
Agreement.

      B. The Merger Agreements provide that, in the Merger, the shares of Hayes
Common Stock and shares of Hayes Series A Preferred Stock that are issued and
outstanding at the Effective Time of the Merger will be converted into shares of
Access Beyond Common Stock and the shares of Hayes Series B Preferred Stock that
are issued and outstanding at the Effective Time of the Merger will be converted
into shares of Access Beyond Series A Stock, all as more particularly set forth
in the Merger Agreement

      C. Shareholder understands that Shareholder is deemed an "affiliate" of
Hayes within the meaning of the Securities Act of 1933, as amended (the "1933
Act"), and that any shares of Access Beyond capital stock acquired by the
Shareholder in the Merger may be disposed of only in conformity with the
limitations described herein.

                                A G R E E M E N T

      1. Tax Treatment, Reliance. Shareholder understands and agrees that it is
intended that the Merger will be treated as a tax-free reorganization for
federal income tax purposes and that such treatment requires that a sufficient
number of former stockholders of Hayes maintain a meaningful continuing equity
ownership interest in Access Beyond after the Merger. Shareholder understands
that the representations, warranties and covenants of Shareholder set forth
herein will be relied upon by Hayes and Access Beyond and their respective
counsel and accounting firms and by Hayes' stockholders. Shareholder will rely
on Shareholder's own tax advisers as to the tax attributes of the Merger to
Shareholder and understands that neither Access Beyond, nor Access Beyond's
counsel, Hayes or Hayes' counsel has guaranteed nor will guarantee to
Shareholder that


                                        1
<PAGE>

the Merger will be a tax-free reorganization, nor shall any of them have any
liability to Shareholder as a result of issuing any opinion in respect thereof
that may be required in connection with any registration statement under the
1933 Act.

      2. Representations, Warranties, and Covenants of Shareholder. Shareholder
represents, warrants and covenants as follows.

            (a) Authority; Affiliate Status. Shareholder has all requisite
right, power, legal capacity and authority to execute, deliver and perform this
Affiliate Agreement and to perform its obligations hereunder. Shareholder
further understands and agrees that Shareholder is deemed to be an "affiliate"
of Hayes within the meaning of the 1933 Act and, in particular, Rule 145
promulgated under the 1933 Act ("Rule 145"),

            (b) Hayes Securities Owned. Attachment 1 hereto sets forth all
shares of Hayes capital stock and any other securities of Hayes owned by
Shareholder, including all securities of Hayes as to which Shareholder has sole
or shared voting or investment power, and all rights, options and warrants to
acquire shares of capital stock or other securities of Hayes granted to or held
by Shareholder (such shares of Hayes capital stock, other securities of Hayes
and rights, options and warrants to acquire shares of Hayes capital stock and
other securities of Hayes are hereinafter collectively referred to as "Hayes
Securities"). As used herein, the term "Expiration Date" means the earliest to
occur of (i) the closing, consummation and effectiveness of the Merger, or (ii)
such time as the Merger Agreement may be terminated in accordance with its
terms.

            (c) New Hayes Securities. As used herein, the term "New Hayes
Securities" means, collectively, any and all shares of Hayes capital stock,
other securities of Hayes and rights, options and warrants to acquire shares of
Hayes capital stock and other securities of Hayes that Shareholder may purchase
or otherwise acquire any interest in (whether of record or beneficially), on and
after the Effective Date of this Affiliate Agreement and prior to the Expiration
Date. All New Hayes Securities will be subject to the terms of this Affiliate
Agreement to the same extent and in the same manner as if they were Hayes
Securities.

            (d) Merger Securities. As used herein, the term "Merger Securities"
means, collectively, all shares of Access Beyond Common Stock, and Access Beyond
Series A Stock that are or may be issued by Access Beyond in connection with the
Merger or the transactions contemplated by the Merger Agreements, or to any
former holder of Hayes options, warrants or rights to acquire shares of Hayes
Common Stock, and any securities that may be paid as a dividend or otherwise
distributed thereon or with respect thereto or issued or delivered in exchange
or substitution therefor or upon conversion thereof.

            (e) Transfer Restrictions on Merger Securities. Shareholder has been
advised that the issuance of the shares of Access Beyond Common Stock and Access
Beyond Series A Stock in connection with the Merger is expected to be
effectuated pursuant to a Registration Statement on Form S-4 under the 1933 Act,
and that the provisions of Rule 145 will limit


                                        2
<PAGE>

Shareholder's resales of such Merger Securities. Shareholder accordingly agrees
not to sell, transfer, exchange, pledge, or otherwise dispose of, or make any
offer or agreement relating to, any of the Merger Securities and/or any option,
right or other interest with respect to any Merger Securities that Shareholder
may acquire, unless: (i) such transaction is permitted pursuant to Rules 145(c)
and 145(d) under the 1933 Act; or (ii) legal counsel representing Shareholder,
which counsel is reasonably satisfactory to Access Beyond, shall have advised
Access Beyond in a written opinion letter reasonably satisfactory to Access
Beyond and Access Beyond's legal counsel, and upon which Access Beyond and its
legal counsel may rely, that no registration under the 1933 Act would be
required in connection with the proposed sale, offer, exchange, pledge or other
disposition of Merger Securities by Shareholder, or (iii) a registration
statement under the 1933 Act covering the Merger Securities proposed to be sold,
transferred, exchanged, pledged or otherwise dispose of, describing the manner
and terms of the proposed sale, transfer, exchange, pledge or other disposition,
and containing a current prospectus, shall have been filed with the Securities
and Exchange Commission ("SEC") and been declared effective by the SEC under the
1933 Act, or (iv) an authorized representative of the SEC shall have rendered
written advice to Shareholder (sought by Shareholder or counsel to Shareholder,
with a copy thereof and all other related communications delivered to Access
Beyond and its legal counsel) to the effect that the SEC would take no action,
or that the staff of the SEC would not recommend that the SEC take action, with
respect to the proposed disposition of Merger Securities if consummated. Nothing
herein imposes upon Access Beyond any obligation to register any Merger
Securities under the 1933 Act.

            (f) Intent. Shareholder does not now have, and as of the Effective
Time of the Merger will not have, any present plan or intention to engage in a
sale, exchange, transfer, distribution, pledge, disposition or any other
transaction which would result in a direct or indirect disposition (a "Sale") of
shares of Access Beyond voting common stock to be issued to Hayes shareholders
in the Merger, which shares would have an aggregate fair market value, as of the
Effective Time of the Merger, in excess of 50% of the aggregate fair market
value, immediately prior to the Merger, of all outstanding shares of Hayes
stock. For purposes of this representation, shares of Hayes stock (or the
portion thereof) (a) with respect to which a Hayes shareholder receives
consideration in the Merger other than Access Beyond voting common stock and/or
(b) with respect to which a Sale by a Hayes shareholder who owns 5% or more of
Hayes stock or is an officer or director of Hayes occurs during the pre-merger
period shall be considered shares of outstanding Hayes stock exchanged for
Access Beyond voting common stock in the Merger and then disposed of pursuant to
a prearranged plan.

      3. Legends. Shareholder also understands and agrees that stop transfer
instructions will be given to Access Beyond's transfer agent with respect to
certificates evidencing the Merger Securities to enforce Shareholder's
compliance with Shareholder's representations in Sections 2(e) and Shareholder's
compliance with applicable securities laws regarding the Merger Securities, and
that there will be placed on the certificates evidencing such Merger Securities
a legend providing substantially as follows:

            15. Hayes Shareholder Agreement. Shareholder acknowledges that the
execution hereof by Shareholder and the execution by any other shareholders of
Hayes of similar agreements in connection with the Merger, is not a violation

the Shareholder Agreement among the shareholders of Hayes dated April 16, 1996.
Shareholder further acknowledges and agrees that this Affiliate Agreement does
not constitute any liquidation or redemption event applicable to the Merger
Securities under the Articles of Incorporation, Bylaws or other organizational

      2. Confidential Information, Trade Secrets. Executive shall not use or

or without Cause.

      3. Inventions. The Company and Executive acknowledge that in the course of
Executive's employment by the Company, Executive may from time to time develop

the Company's copyrights, patents, and other proprietary rights therein and, to
the extent deemed desirable by the Company, in the registration of the same.
Executive hereby assigns to the Company all of Executive's right, title and
interest in and to any and all inventions, processes, systems and creations,
whether or not patentable or copyrightable, that Executive may conceive,
develop, or create, in whole or in part, during his employment with the Company,

electronic form.

      5. Protective Covenants. Executive is and will during the course of
employment become intimately familiar with Confidential Information, trade
secrets, facilities and services, and other property of the Company, and the

Company's benefit, not to be disclosed to any other party or used by Executive
against 


                                      - 7 -

            eighteen (18) months from the termination of his employment with
            Company, whether with or without Cause, he shall not, directly or
            indirectly, on behalf of himself or any other person or entity,
            compete with the Company within a fifty (50) mile radius of the
            Company's principal place of business in Norcross, Georgia, or its
            principal place of business in Gaithersburg, Maryland, by engaging
            in the manufacture, assembling, or selling of computer component
            products, software, or systems, including modems, competitive with
            those manufactured, assembled, or sold by the Company, in a capacity
            which requires Executive to perform services substantially identical
            to the services performed by Executive on behalf of Company.

      (ii)  Covenant Not to Solicit Customers. During the term of Executive's
            employment hereunder, and for a period of eighteen (18) months
            following the termination of such employment for any reason
            whatsoever, Executive shall not (except on behalf of or with the
            prior written consent of Company), either directly or indirectly, on
            Executive's own behalf or on behalf of others, solicit, divert, or
            appropriate any business for the manufacture, assembling, or sale of
            computer component products, software or systems, including modems,
            competitive with those manufactured, assembled or sold by the
            Company, from any customer or actively sought prospective customer
            of the Company to whom the Company offered or provided products or
            services, and with whom Executive had material contact at any time
            during the twenty-four (24) months preceding the termination of
            Executive's employment.

      (iii) Covenant Not to Solicit Employees. During the term of Executive's
            employment hereunder, and for a period of eighteen (18) months
            following the termination of such employment for any reason
            whatsoever, Executive shall not employ or solicit the employment of
            any employee of the Company who was an employee of the Company at
            any time during the six (6) months preceding the termination of
            Executive's employment with the Company, for the purpose of causing
            such employee to take employment with Executive or a competitor of
            the Company.

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

      6. Survival. Paragraphs 2, 3, 4, 5, and 6 hereof, together with any
provisions of the Company's Operations Policies expressly or by necessary
implication applicable after the termination of employment, shall survive
termination of this Agreement. Upon termination, Executive shall repay to
Company immediately any advances by Company, not offset by earnings or other
credits due him or her, even if not expressly made repayable at the time of such
advance, it being the intent of the parties that all such advances shall be
repayable as provided by this


                                      - 8 -
<PAGE>

paragraph. Company may offset any sums owed to Company by Executive against any
amounts otherwise owed by Company to Executive. No sums otherwise due Executive
at termination shall be payable to Executive if, at the time of termination or
thereafter, Executive shall be in violation of any term or provision of this
Agreement.

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

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

      9. Binding Effect. This Agreement shall be binding upon, and shall inure

eliminate any ambiguity as to the ownership by and rights of the Company in such
Confidential Information and Trade Secrets including, without limitation,
providing to the Company his full cooperation in any litigation, unless between
the Executive and the Company after termination of Executive's employment, or
other proceeding to establish, protect or obtain such ownership and rights. Upon
request by the Company, and in any event upon termination of his employment with
the Company for any reason, the Executive shall promptly deliver to the Company
all property belonging to the Company, including, without limitation, all
Confidential Information and Trade Secrets (and all embodiments thereof) then in
his custody, control or possession.

      6.4 Non-Disclosure. The Executive agrees that, during the term of his
employment by the Company and (i) at all times following the termination of such
employment for any reason whatsoever, with respect to Trade Secrets under the
Georgia Trade Secrets Act and (ii) during the Restricted Period with respect to
other Confidential Information, he will not use, disclose or make available,
directly or indirectly, any Confidential Information or Trade Secrets to any
person, concern or entity, except in the performance of his duties and
responsibilities hereunder or with the prior written consent of the Company. The
provisions of this Section 6 shall continue after the Term as provided herein
and shall survive irrespective of the reason the Executive's employment
terminates.

                          7. Inventions and Trademarks.

      7.1   Definition of Invention and Executive Invention.

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

            7.1.2 For the purposes of this Section 7, Executive Invention shall
      mean any Invention which is conceived by the Executive or conceived by the
      Executive in a joint effort with others during the Executive's employment
      by the Company which (i) may be reasonably expected to be used in a
      current product of the Company, a projected future product of the Company,
      or a product similar to a Company product; (ii) results from work


                                     - 11 -
<PAGE>

      that the Executive has been assigned as part of his duties as an
      employee, officer or director of the Company; (iii) is in an area of
      technology which is the same or substantially related to the areas of
      technology with which the Executive is involved in the performance of the
      Executive's duties as an employee, officer or director of the Company;
      (iv) is useful, or which may reasonably be expected to be useful, in any
      manufacturing process, product design or internal control system of the
      Company; or (v) is in an area of technology which includes machinery or
      processes with which the Executive normally works in performing his duties
      as an employee, officer or director of the Company.

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

      7.3 Conception of Invention. The Executive hereby agrees that if he
conceives any Invention during his employment, for which there is a reasonable
basis to believe that the conceived Invention may be an Executive Invention, the
Executive will provide notice containing a written description of the Invention
to each Board member, adequate to allow evaluation thereof by the Board for a
determination of whether the Invention is an Executive Invention. In the event
of any dispute regarding such determination, the dispute shall be resolved
pursuant to Section 9 hereof.

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

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

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

                      8. Breach of Covenants by Executive.

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

      resolution.

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

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

      discretion of the designated representatives but may include the
      preparation of agreed upon statements of fact or written statements of
      position furnished to the other party.

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

                               10. Miscellaneous.

      10.1 Key Man Insurance. The Executive agrees that during the Term, the
Company in its sole discretion may purchase in addition to those specified in

Company.

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

      10.3 Severability. If any provision of this Agreement shall be held to be
illegal, invalid or unenforceable, such provision shall be enforced to the
maximum extent permissible so as to effect the intent of the parties, and the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

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

      10.5 Entire Agreement. This Agreement embodies the entire agreement of the
parties hereto relating to the subject matter hereof. This Agreement supersedes
all prior and contemporaneous agreements, understandings, negotiations and
discussions, written or oral, of the parties hereto, relating to the subject
matter of this Agreement. Nothing in this Agreement is intended or shall confer
upon or give any person other than the parties hereto any rights or remedies
under or by reason of this Agreement.

      10.6 No Amendments. No amendments or modifications of this Agreement shall
be valid or binding upon the Company unless made in writing and approved by the
Board and signed by a Board member duly authorized by the Board (other than a
Board member designated by the Executive or the Executive), or upon the
Executive unless made in writing and signed by the Executive.

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

Exhibit 1.5A

                             CERTIFICATE OF OFFICER
                             OF ACCESS BEYOND, INC.

            The undersigned officer of Access Beyond, Inc., a Delaware
corporation ("Acquirer"), and _________________, a Georgia corporation
("Newco"), on behalf of Acquirer and Newco, respectively, after consulting with
legal counsel and financial auditors regarding the meaning of and the factual
support for the following representations, hereby represent, in connection with
the proposed merger of Hayes Microcomputer Products, Inc., a Georgia corporation
("Target"), with and into Newco, with Target surviving the merger and with
Target shareholders receiving solely Acquirer voting stock in the merger,
intended to qualify as a reorganization described in ss. 368(a)(1)(A) of the
Internal Revenue Code of 1986, as amended (the "Code"), by virtue of the
provisions of ss. 368(a)(2)(E), collectively referred to as the "Merger,"
pursuant to that certain Agreement and Plan of Reorganization by and between
Acquirer, Newco and Target, dated as of _______________, 1997, and Exhibits
thereto (collectively the "Agreement"),(1) that to the best of their knowledge
and belief the following facts are now true, correct and complete; and will
continue to be true, correct and complete as of the Effective Time for the
Merger and thereafter, as relevant.

            1. Newco is a newly-formed corporation that was created for the sole
purpose of facilitating Acquirer's acquisition of Target. It has not conducted
and is not conducting any business activities. Newco will hold only those assets
necessary for it to effect the Merger.

            2. Following the transaction, Target will hold at least 90% of the
fair market value of its net assets, at least 70% of the fair market value of
its gross assets, at least 90% of the fair market value Newco's net assets, and
at least 70% of the fair market value of Newco's gross assets held immediately
prior to the transaction. For purposes of this representation, amounts paid by
Target or Newco to dissenters, amounts paid by Target or Newco to shareholders
who receive cash or other property, amounts used by Target or Newco to pay
reorganization expenses, all redemptions and distributions (except for regular,
normal dividends) made by Newco, and Newco assets disposed of by Newco prior to
the Merger and in contemplation thereof (including without limitation any asset
disposed of by Newco, other than in the ordinary course of business, during the
period ending on the Effective Time and beginning with the commencement of
negotiations, whether formal or informal, between Target and Acquirer regarding
the Merger (the "Pre-Merger Period")), will be included as assets of Target or
Newco, respectively, immediately prior to the transaction.

            3. Prior to the Merger, Acquirer will be in Control of Newco. As
used herein, "Control" shall mean ownership of stock possessing at least 80% of
the total combined voting power of all classes of stock entitled to vote and at
least 80% of the total combined voting power of all classes of stock entitled to
vote and at least 80% of the total number of shares of all other classes of
stock of the corporation. For purposes of determining Control, a person shall
not be considered to own voting stock if rights to vote such stock (or to
restrict or otherwise control the voting of such

- ----------
      (1) Unless otherwise indicated, all capitalized terms shall have the
meaning defined in the Agreement.
<PAGE>

stock) are held by a third party (including a voting trust) other than an agent
of such person.

            4. Acquirer will acquire Control of Target in the Merger solely in
exchange for Acquirer voting stock.

            5. The Conversion Ratio as defined in paragraph 1.1.5 of the
Agreement is the result of arm's length bargaining. The fair market value of the
Acquirer voting common stock to be received by shareholders to Target will be
approximately equal to the fair market value of the Target common stock and
Target Series A preferred stock to be surrendered in exchange therefor. The fair
market value of the Acquirer Series A preferred stock to be received by
shareholders of Target will be approximately equal to the fair market value of
the Target Series B Preferred Stock to be surrendered in exchange therefor. The
fair market value of the substituted Acquirer options to be received by the
Target option holders will be approximately equal to the fair market value of
the Target options to be assumed in exchange therefor. The fair market value of
the substituted Acquirer warrants to be received by the Target warrant holders
will be approximately equal to the fair market value of the Target warrants to
be assumed in exchange therefor.

            6. The Acquirer common stock to be exchanged for Target common stock
in the Merger will be newly issued Acquirer stock.

            7. Acquirer has no plan or intention to cause Target to issue, after
the Merger, additional shares of stock (or rights to acquire shares of Target
stock) that would result in Acquirer losing Control of Target.

            8. Acquirer has no plan or intention to reacquire any of its voting
stock issued in the Merger. For purposes of this representation, it should be
noted that Acquirer may from time to time repurchase some of its issued and
outstanding stock in open market repurchase transactions. Acquirer has no plan
or intention to make any extraordinary distribution with respect to its voting
stock issued in the Merger.

            9. Acquirer has no plan or intention to: (a) cause Target to sell,
transfer or otherwise dispose of any of its assets or any of the assets acquired
from Newco except for dispositions made in the ordinary course of business or
for the payment of expenses incurred by Target in the Merger; (b) liquidate
Target; (c) merge Target with or into another corporation including Acquirer or
its affiliates; or (d) to sell, distribute or otherwise dispose of the stock of
Target.

            10. In the Merger, Newco will have no liabilities assumed by Target
and will not transfer to Target any assets subject to liabilities.

            11. Acquirer intends that, immediately following the Merger, Target
will continue its historic business or use a significant portion of its historic
business assets in a business.


                                       2
<PAGE>

            12. Neither Acquirer nor any Acquirer subsidiary owns, or has owned
during the past five years, directly or indirectly, any shares of Target stock,
or the right to acquire or vote any such stock.

            13. No shareholder of Target is acting as agent for Acquirer in
connection with the Merger or approval thereof.

            14. The transfer of cash to Target shareholders in lieu of
fractional Acquirer voting common stock shares, if any, is solely for the
purpose of avoiding the expense and inconvenience to Acquirer of accounting for
fractional shares and does not represent separately bargained-for consideration.

            15. Except with respect to payments of cash to Target shareholders
in lieu of fractional shares of Acquirer voting stock and cash paid for Target
Dissenting Shares, if any, 100% of the Target stock outstanding immediately
prior to the Merger will be exchanged solely for Acquirer voting stock. In any
event, the total consideration other than Acquiring voting stock received by
Target Shareholders will be less than 20% of the total fair market value of the
Target stock outstanding immediately prior to the Merger. Thus, except as set
forth in the preceding sentences, Acquirer intends that no consideration other
than Acquirer voting stock be paid or received (directly or indirectly, actually
or constructively) for Target stock.

            16. No shares of Newco have been or will be used as consideration or
issued to shareholders of Target in the Merger.

            17. Newco and Acquirer will each pay separately its own expenses in
connection with the Merger as contemplated by the Agreement.

            18. There is no inter-corporate indebtedness existing between
Acquirer and Target or between Newco and Target that was issued, acquired, or
will be settled at a discount, and Acquirer will assume no liabilities of Target
or any Target shareholder in connection with the Merger.

            19. None of the payments to be received by any shareholder of Target
that are designated as compensation are actually separate consideration for, or
allocable to, any of their shares of Target stock, and the compensation to be
paid to any shareholder of Target will be for services actually rendered and
will be commensurate with amounts paid to third parties bargaining at arm's
length for similar services.

            20. Neither Acquirer nor Newco are investment companies as defined
in ss. 368(1)(2)(F) of the Code.

            21. The Merger is to be carried out for a substantial business
purpose.

            22. Acquirer and Newco are authorized to make all of the
representations set forth


                                       3
<PAGE>

herein, and the undersigned are authorized to execute this certificate on behalf
of Acquirer and Newco.

            The undersigned recognize that counsel to and auditors for Target
and counsel to and auditors for Acquirer and Newco will rely upon the foregoing
representations in evaluating the U.S. federal income tax consequences of the

                                                             July 24, 1997 Draft

Exhibit 1.5B

                             CERTIFICATE OF OFFICER
                      OF HAYES MICROCOMPUTER PRODUCTS, INC.

            The undersigned officer of Hayes Microcomputer Products, Inc., a
Georgia corporation ("Target"), on behalf of the management of Target, after
consulting with legal counsel and financial auditors regarding the meaning of
and the factual support for the following representations, hereby represent, in
connection with the proposed merger of Target with and into _________________, a
Georgia corporation ("Newco"), a wholly owned subsidiary of Access Beyond, Inc,
a Delaware corporation ("Acquirer"), with Target surviving the merger and with
Target shareholders receiving solely Acquirer voting stock in the merger,
intended to qualify as a reorganization described in ss. 368(a)(1)(A) of the
Internal Revenue Code of 1986, as amended (the "Code"), by virtue of the
provisions of ss. 368(a)(2)(E), collectively referred to as the "Merger,"
pursuant to that certain Agreement and Plan of Reorganization by and between
Acquirer, Newco and Target, dated as of _______________, 1997, and Exhibits
thereto (collectively the "Agreement"),(1) that to the best of their knowledge
and belief the following facts are now true, correct and complete; and will
continue to be true, correct and complete as of the Effective Time for the
Merger and thereafter, as relevant.

            1. At least 90% of the fair market value of its net assets and at
least 70% of the fair market value of the gross assets held by Target
immediately before the Merger during the Pre-Merger Period will be held by
Target immediately after the Merger. For the purpose of determining the
percentage of the net and gross assets held by Target immediately before the
Merger for purposes of this representation, the following assets will be treated
as property held by Target immediately prior but not subsequent to the Merger:
(a) assets disposed of by Target prior to the Merger and in contemplation
thereof (including without limitation any asset disposed of by Target, other
than in the ordinary course of business, during the period ending on the
Effective Time of the Merger and beginning with the commencement of negotiations
(whether formal or informal) between Target and Acquirer regarding the merger
(the "Pre-Merger Period")), (b) assets used by Target to pay expenses or
liabilities incurred in connection with the Merger, and (c) assets used to make
distributions (except for regular and normal dividends), redemption or other
payments in respect of Target stock or rights to acquire such stock (including
payments treated as such for tax purposes) that are made in contemplation of the
merger or related thereto.

            2. Target has made no transfer of any of its assets (including any
distribution of assets with respect to, or in redemption of, stock) in
contemplation of the Merger or during the Pre-Merger Period other than (a) in
the ordinary course of business, and (b) payments for expenses incurred in
connection with the Merger.

- ----------
      (1) Unless otherwise indicated, all capitalized terms shall have the
meaning defined in the Agreement.
<PAGE>

            3. In the Merger, shares of Target stock representing Control of
Target will be exchanged solely for voting stock of Acquirer; at the time of the
Merger, there will exist no rights of any kind (including without limitation,
warrants, options, convertible securities, contingent rights, informal or
unwritten rights) to acquire Target stock or to vote (or restrict or otherwise
control the vote of) Target stock, which, if exercised, could affect Acquirer's
acquisition and retention of Control of Target. For purposes of this
representation, shares of Target stock exchanged in the Merger for cash and
other property will be treated as Target stock outstanding on the date of the
Merger but not exchanged for voting stock of Acquirer. As used herein, the term
"Control" shall mean ownership of stock possessing at least 80% of the total
combined voting power of all classes of stock entitled to vote and at least 80%
of the total number of shares of all other classes of stock of the corporation.
For purposes of determining Control, a person shall not be considered to own
voting stock if rights to vote such stock (or to restrict or otherwise control
the voting of such stock) are held by a third party (including a voting trust)
other than an agent of such person.

            4. At the Effective Time of the Merger, there will be no accrued but
unpaid dividends on shares of Target stock.

            5. The Conversion Ratio as defined in paragraph 1.1.5 of the
Agreement is the result of arm's length bargaining. The fair market value of the
Acquirer voting common stock to be received by shareholders of Target will be
approximately equal to the fair market value of the Target common stock and
Target Series A voting preferred stock to be surrendered in exchange therefor.
The fair market value of the Acquirer Series A preferred stock to be received by
shareholders of Target will be approximately equal to the fair market value of
the Target Series B preferred stock to be surrendered in exchange therefor. The
fair market value of the substituted Acquirer options to be received by the
Target option holders will be approximately equal to the fair market value of
the Target options to be assumed in exchange therefor. The fair market value of
the substituted Acquirer warrants to be received by the Target warrant holders
will be approximately equal to the fair market value of the Target warrants to
be assumed in exchange therefor.

            6. At the Effective Time of the Merger, the fair market value of the
assets of Target will exceed the sum of its liabilities, plus the amount of
liabilities, if any, to which its assets are subject.

            7. Target has no obligation, understanding, agreement or intention
to issue additional shares of stock after the Merger that would result in
Acquirer losing Control of Target.

            8. Target has no plan or intention, and is under no obligation, to
discontinue its business, to sell or otherwise dispose of any of its assets or
of any of the assets acquired from Newco in the Merger except for dispositions
made in the ordinary course of business or the payment of expenses incurred by
Target pursuant to the Merger.

            9. There is no plan or intention on the part of any Target
shareholder who owns 5% or more of Target stock or is an officer or director of
Target, and to the knowledge of the


                                        2
<PAGE>

management of Target, there is no plan or intention on the part of the remaining
Target shareholders to engage in a sale, exchange, transfer, distribution,
pledge, disposition or any other transaction which would result in a direct or
indirect disposition (a "Sale") of shares of Acquirer voting stock to be issued
to Target shareholders in the Merger, which shares would have an aggregate fair
market value, as of the Effective Time of the Merger, in excess of 50% of the
aggregate fair market value, immediately prior to the Merger, of all outstanding
shares of Target stock. For purposes of this representation, shares of Target
stock (or the portion thereof) (a) with respect to which a Target shareholder
receives consideration in the Merger other than Acquirer voting common stock
and/or (b) with respect to which a Sale by a Target shareholder who owns 5% or
more of Target stock or is an officer or director of Target occurs during the
Pre-Merger Period shall be considered shares of outstanding Target stock
exchanged for Acquirer voting stock in the Merger and then disposed of pursuant
to a prearranged plan.

            10. Target has no plan or intention to immediately reacquire any of
the voting stock issued to its shareholders in the Merger.

            11. Target intends that, immediately following the Merger, Target
will continue its historic business or use a significant portion of its historic
business assets in a business.

            12. The transfer of cash to Target shareholders in lieu of
fractional Acquirer voting common stock shares, if any, is solely for the
purpose of avoiding the expense and inconvenience to Acquirer of accounting for
fractional shares and does not represent separately bargained-for consideration
by the Target Shareholders.

            13. Except with respect to payments of cash to Target shareholders
in lieu of fractional shares of Acquirer voting stock and cash paid for Target
Dissenting Shares, if any, 100% of the Target stock outstanding immediately
prior to the Merger will be exchanged solely for Acquirer voting stock. In any
event, the total consideration other than Acquiring voting stock received by
Target Shareholders will be less than 20% of the total fair market value of the
Target stock outstanding immediately prior to the Merger. Thus, except as set
forth in the preceding sentences, Acquirer intends that no consideration other
than Acquirer voting stock be paid or received (directly or indirectly, actually
or constructively) for Target stock.

            14. Target and the shareholders of Target will each pay separately
its or their own expenses in connection with the Merger as contemplated by the
Agreement.

            15. There is no inter-corporate indebtedness existing between
Acquirer and Target or between Newco and Target that was issued, acquired, or
will be settled at a discount, and the knowledge of the management of Target,
Acquirer will assume no liabilities of Target or any Target shareholder in
connection with the Merger.


                                        3
<PAGE>

            16. There is no indebtedness existing between Target and any Target
shareholder which will be repaid in connection with or as part of the Merger, or
will be specifically funded with amounts Acquirer would contribute to Target
subsequent to the Merger.

            17. None of the payments to be received by any shareholder of Target
which have been designated as compensation are actually separate consideration
for, or allocable to, any of their shares of Target stock; and the compensation
paid to any shareholder of Target will be for services actually rendered and
will be commensurate with amounts paid to third parties bargaining at arm's
length for similar services.

            18. Target is not an investment company as defined in ss.
368(a)(2)(F) of the Code, and is not under the jurisdiction of a court in a
Title 11 or similar case within the meaning of ss. 368(a)(3)(A) of the Code.

            19. The Merger is to be carried out for a substantial business
purpose.

            20. Target is authorized to make all of the representations set
forth herein, and the undersigned are authorized to execute this certificate on
behalf of Target.

            The undersigned recognize that counsel to and auditors for Target
and counsel to and auditors for Acquirer and Newco will rely upon the foregoing
representations in evaluating the federal income tax consequences of the Merger.

                                       OF
                               ACCESS BEYOND, INC.
                   (Originally Incorporated on July 23, 1996)

name of its registered agent at that address is The Corporation Trust Company.

                                   ARTICLE III

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

                                   ARTICLE IV

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

$.01 par value per share. __________________ (____(1)____) shares of the
Preferred Stock are designated as Series A Preferred Stock.

      The Board of Directors is authorized, subject to any limitations
prescribed by the law of the State of Delaware, to provide for the issuance of
the shares of Preferred Stock in one or more series, and, by filing a
certificate of designation pursuant to the applicable law of the State of
Delaware, to establish from time to time the number of shares to be included in
each such series, to fix the designation, powers, preferences and rights of the
shares of each such wholly unissued series and any qualifications, limitations
or restrictions thereof, and to increase or decrease the number of shares of any
such series (but not below the number of shares of such series then

<PAGE>

decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the stock of the Corporation
entitled to vote, unless a vote of any other holders is required pursuant to a
certificate or certificates establishing a series of Preferred Stock.

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

                                   ARTICLE V

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

      1. Dividend Rights. The holders of Series A Preferred Stock shall be
entitled to receive, as and when declared by the Board, but only out of funds
legally available therefor, cumulative compounding dividends at the dividend
rate of ten percent (10%) per annum of $______. [this blank will equal the
original issue price per share of Hayes Series B Preferred Stock ($20.9036)
divided by the Conversion Ratio] Dividends shall accrue quarterly as if such
dividends had commenced to accrue on April 24, 1997, provided, however, that in
the event of conversion of the Series A Preferred Stock (as set forth in Section
3), dividends shall be accrued through the day immediately prior to such
conversion. Subject to the restrictions set forth in this Section 1, dividends
accumulated on the Series A Preferred Stock shall be declared by the Board and
paid on the Redemption Date provided that the Redemption Request is provided as
set forth in Section 7. Such dividends shall be paid in cash upon redemption, or
in additional shares of Common Stock upon conversion of the Series A Preferred
Stock as provided in Section 3 below. Dividends accumulated on the Series A
Preferred Stock shall be declared by the Board and paid in cash every three (3)
months to the extent permitted by law. No dividends may be paid on the Common
Stock unless all accrued and unpaid dividends on the Series A Preferred Stock
are paid.

      2. Voting Rights.

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

            (b) Preferred Stock. Each holder of shares of Series A Preferred
      Stock shall be entitled to the number of votes equal to the number of
      whole shares of Common Stock into which such shares of Series A Preferred
      Stock could be converted pursuant to the


                                       2
<PAGE>

      provisions of Section 3 below at the record date for the determination of
      the shareholders entitled to vote on such matters or, if no such record
      date is established, the date such vote is taken or any written consent of
      shareholders is solicited.

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

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

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

            (b) Automatic Conversion. Each share of Series A Preferred Stock
      shall automatically be converted (as set forth below) into such number of
      fully paid and nonassessable shares of Common Stock as determined by
      dividing US $_____ [this blank will equal $20.9036 divided by the
      Conversion Ratio] (adjusted for any stock splits, stock dividends, stock
      combinations or similar events) plus the per share amount of all unpaid
      and accrued dividends on the Series A Preferred Stock existing immediately
      prior to the conversion of the Series A Preferred Stock by the Series A
      Conversion Price, determined as hereinafter provided, in effect (i)
      immediately prior to the consummation of a Qualified Public Offering (as
      defined below) under the Securities Act of 1933, as amended (the
      "Securities Act"); or (ii) at such time as the Corporation has registered


                                       3
<PAGE>

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

            (c) Mechanics of Conversion.

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


                                       4
<PAGE>

                        such holder elects to convert the same and shall state
                        therein the name or names in which such holder wishes
                        the certificate or certificates for shares of Common
                        Stock to be issued. The Corporation shall, as soon as
                        practicable thereafter, issue and deliver at such office
                        to such holder of Series A Preferred Stock, a
                        certificate or certificates for the number of shares of
                        Common Stock to which such holder shall be entitled as

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

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

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

                        (A)   Cash and Property. Such consideration shall:


                                       9
<PAGE>

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

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

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

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

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

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

            (e) Adjustments for Stock Dividends, Subdivisions, or Split-ups of
Common Stock. If the number of shares of Common Stock outstanding at any time
after the filing of this Restated Certificate of Incorporation is increased by a
stock dividend payable in shares of Common Stock or by a subdivision or split-up
of shares of Common Stock, then, effective at the close of business upon the
record date fixed for the determination of holders of Common Stock entitled to
receive such stock dividend, subdivision or split-up, the Series A Conversion
Price shall be appropriately decreased so that the number of shares of Common
Stock issuable on conversion of each share of Series A Preferred Stock shall be
increased in proportion to such increase of outstanding shares of Common Stock.

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

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

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


                                       11
<PAGE>

have been subject to receipt by the holders upon conversion of the Series A
Preferred Stock immediately before such event; and, in any such case,
appropriate adjustment (as determined by the Board) shall be made in the
application of the provisions herein set forth with respect to the rights and
interests thereafter of the holders of the Series A Preferred Stock, to the end
that the provisions set forth herein (including provisions with respect to
changes in and other adjustments of the Series A Conversion Price) shall
thereafter be applicable, as nearly as may be reasonable, in relation to any
shares of stock or other property thereafter deliverable upon the conversion of
the Series A Preferred Stock. In the event of any conflict between this Section
3(h) and Section 4(b), Section 4(b) shall be controlling.

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

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

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

                  (A)   at least twenty (20) days' prior written notice of the
                        date on which a record shall be taken for such dividend,
                        distribution or 


                                       12
<PAGE>

                        subscription rights (and specifying the date on which
                        the holders of Common Stock shall be entitled thereto)
                        or for determining rights to vote, if any, in respect of
                        the matters referred to in (c) and (d) above; and

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

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

            (m) Reservation of Stock Issuable Upon Conversion. The corporation
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series A Preferred Stock, such number of its shares of Common
Stock as shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series A Preferred Stock; and if at any time the
number of authorized but unissued shares of Common Stock shall not be sufficient
to effect the conversion of all then outstanding shares of the Series A
Preferred Stock, the Corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purpose, including, without limitation, engaging in its best efforts to obtain
the requisite stockholder approval of any necessary amendment to the Certificate
of Incorporation.

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

            (o) Notices. Any notice required by the provisions of this Section 3
to be given to the holders of shares of Series A Preferred Stock shall be given
in writing and it or any certificates or other documents delivered hereunder
shall be deemed effectively given or delivered (as the case may be) upon
personal delivery; when deposited with a recognized international 


                                       13
<PAGE>

courier, five (5) days after deposit (or if earlier, upon delivery against a
signed receipt therefor); when transmitted by telecopy, which transmission is
confirmed, at the address appearing on the books of the Corporation.

      4. Liquidation Rights.

            (a) In the event of any liquidation, dissolution or winding up of
the Corporation, whether voluntary or involuntary, the holder of each share of
the Series A Preferred Stock then outstanding shall be entitled to receive out
of the remaining assets of the Corporation available for distribution to
stockholders, and before any payment or declaration and setting apart for
payment of any amount shall be made in respect of Common Stock, an amount equal
to $________. [this blank will equal the original issue price per share of Hayes
Series B Preferred Stock ($20.9036) divided by the Conversion Ratio] (which
amount shall be adjusted proportionately in the event the shares of Series A
Preferred Stock are subdivided into a greater number or combined into a lesser
number) plus an amount equal to any accrued but unpaid dividends through the
date of such liquidation, dissolution or winding up of the Corporation (the
"Series A Preferred Stock Liquidation Preference"). If, upon any liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the assets to be distributed to the holders of Series A Preferred Stock shall be
insufficient to permit the payment of the full Series A Preferred Stock
Liquidation Preference pursuant to this Section 4(a), then all of the remaining
assets of the Corporation to be distributed shall be distributed ratably to the
holders of Series A Preferred Stock.

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

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

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


                                       14
<PAGE>

                        (B)   If actively traded over the counter and not
                              reported on a national inter dealer quotation
                              system, the value shall be deemed to be the
                              average of the closing bid prices over the 30-day
                              period ending three (3) days prior to the closing;
                              and

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

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

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

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

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

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

            (iii) authorize or issue, or obligate itself to issue, any other
                  equity security senior to or on a parity with the Series A
                  Preferred Stock as to dividends 


                                       15
<PAGE>

                  or assets in liquidation or create or reclassify any
                  obligation or security convertible into or exchangeable for,
                  or having any option rights to purchase, any such equity

A Preferred Stock acquired by the Corporation by reason of purchase, conversion

issue. The corporation may, from time to time, take such appropriate corporate
action as may be necessary to reduce the authorized number of shares of the
Series A Preferred Stock, but not below the number of shares of such Series then
outstanding.

      7. Redemption.

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


                                       16
<PAGE>

            (b) Stockholder Redemption Request. Subject to the limitations set
forth herein and in Section 7(f) below, on ninety (90) days prior written notice
from the holders of more than fifty percent (50%) of the Series A Preferred
Stock ("Redemption Request") delivered to the Corporation not earlier than
November 1, 1999, the Corporation shall redeem all of the shares of Series A
Preferred Stock held by each holder as of the date of such notice by paying in
cash therefor, US $_________ [this blank will equal $20.9036 divided by the
Conversion Ratio] per share of Series A Preferred Stock (such amount to be
adjusted proportionately in the event the shares of Series A Preferred Stock are
subdivided into a greater number or combined into a lesser number and in the
event the Corporation at any time pays a dividend, or makes any other
distribution, to holders of Series A Preferred Stock payable in shares of Series
A Preferred Stock) plus all accrued but unpaid dividends on such shares (the
"Redemption Price") on such Redemption Date.

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

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

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


                                       17
<PAGE>

except only the right of the holder to receive the Redemption Price upon
surrender of the certificate evidencing such shares.

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

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

                                   ARTICLE VI

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

                                   ARTICLE VII

            The number of directors shall be fixed from time to time exclusively
by the Board of Directors pursuant to a resolution adopted by the affirmative
vote of a majority of the entire Board of Directors. The directors shall be
divided into three classes, designated as Class I, Class II and Class III. Each
class shall consist, as nearly as possible, of one-third of the total number of
directors, initially, with the directors of Class I elected for a term of one
year, the directors of 


                                       18
<PAGE>

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

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

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


                                       19
<PAGE>

            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 IV), and such
Directors so elected shall not be divided into classes pursuant to this Article
VII unless expressly provided by such terms.

                                  ARTICLE VIII

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

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

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

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

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

                  When and as authorized by the stockholders in accordance with
            this Certificate of Incorporation and applicable statutes, to sell,
            lease or exchange all or substantially all of the property and
            assets of the Corporation, including its goodwill and its corporate
            franchises, upon such terms and conditions and for such
            consideration (which may consist, in whole or in part, of money or


                                       20

            property, including shares of stock in, and/or other securities of,
            any other corporation or corporations) as the Corporation's Board of
            Directors shall deem appropriate and in the best interests of the
            Corporation.

                                   ARTICLE IX

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

any provision of this Restated Certificate of Incorporation inconsistent with
this Article IX, shall eliminate, reduce or otherwise adversely affect any
limitation on the personal liability of a director of the Corporation existing
at the time of such amendment, repeal or adoption of such an inconsistent
provision.

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

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

FOR IMMEDIATE RELEASE

         ACCESS BEYOND, INC. AND HAYES MICROCOMPUTER PRODUCTS, INC. SIGN

       -New Company to Apply Brand Name Strengths, Advanced Communications
     Technologies and Low Cost Manufacturing Capabilities to Global Market-

GAITHERSBURG, MD, and ATLANTA, GA, July 30, 1997 - Access Beyond, Inc.
(Nasdaq:ACCB), a provider of remote access connectivity products, and
privately-held Hayes Microcomputer Products, Inc., a $250 million pioneer in
computer communications technology, jointly announced today the signing of a
definitive merger agreement. Under the terms of the Agreement, Access Beyond
will be renamed Hayes Communications Inc. and its stock will continue to be
traded on Nasdaq. Access Beyond shareholders will own approximately 21% of the
outstanding shares of Hayes Communications Inc.

Hayes has long been credited with having a well established, multi-channel
sales, marketing and distribution network, which will provide the "engine" to
commercialize Access Beyond's RAS technology to the broad business market. The
new company, Hayes Communications Inc., will drive market acceptance of
aggressively priced technology by offering quality products, brand name
recognition, low cost manufacturing and access to global distribution. The
combined resources of the two companies is expected to result in faster time to
market and create the opportunity for accelerated growth, improved margins and
increased shareholder value.

Dennis Hayes, age 47, founder and Chairman of Hayes, will become Chairman of
Hayes Communications; with Ron Howard, age 41, Chairman and Chief Executive
Officer of Access Beyond, set to become Vice-Chairman and Executive Vice
President of Business Development. Joseph Formichelli, age 54, President and
Chief Executive Officer of Hayes, will become President and Chief Executive
Officer of the new company. Together, they will form the Senior Management
Committee of Hayes Communications.

Ron Howard stated, "The new company to emerge from this marriage will quickly
become known as a strong innovator in the burgeoning remote access marketplace.
Access Beyond's family of high-quality, low-cost remote access solutions,
including recently introduced technologies for Microsoft Windows NT servers,
coupled with Hayes' brand name recognition in the computer communications
industry, state-of-the-art manufacturing capabilities and full service
multi-channel sales, marketing and distribution network, creates a formidable
company with tremendous growth potential. I look forward to working closely with
Dennis to realize the vision we share for our new company, and am confident that
together with Joe, we can build a company that will provide lasting shareholder
value."

Dennis Hayes commented, "It has long been Hayes' vision to create a company that
could provide a wide range of high quality communications products to serve the
rapidly evolving Virtual Workplace. One of the historic strengths of Hayes has
been the Company's ability to successfully create market acceptance for state of
the art technologies. We see Access Beyond as a low-cost provider of RAS
solutions, products which we believe can be readily sold through Hayes'
extensive global distribution channels, and will have wide appeal for our
existing customers. In addition, by combining the two companies, we expect to
achieve significant synergies."

"As the new company, Hayes Communications, should grow and benefit under the
leadership of a strong and seasoned management team," continued Mr. Hayes. "Ron,
Joe and I intend to work closely together to define new market opportunities and
identify strategic partners and potential acquisition candidates to expand our
technologies, products and geographic reach. During the past year, Joe has made
a significant contribution to the Hayes organization, drawing on his broad
background in executive management. Prior to joining Hayes, Joe was Vice
President of Operations for the IBM PC Company, where he directed the worldwide
manufacturing, logistics and procurement divisions. We believe that Joe,
supported by an excellent management team with many years of industry
experience, is poised to lead the new organization to new heights within the
computer communications industry."

Joseph Formichelli commented, "Hayes has been building momentum over the past
few months as evidenced by our recently announced financial results that
reported a 42% increase in revenues from the first to second quarter, along with
a significant gain in backlog. We feel the addition of Access Beyond's products
and technologies will provide the necessary fuel to help continue this momentum.
In addition, the combination of the two companies will bring together a very
talented group of senior management who will provide the knowledge and expertise
to facilitate Hayes Communications' emergence as a leading computer
communications company."

Under the terms of the agreement, Access Beyond will issue approximately 45
million shares of its common stock for all outstanding shares of Hayes. Access
Beyond currently has approximately 12.5 million shares outstanding. Based on
Access Beyond's closing price yesterday, the combined Company would have a
market capitalization of approximately $339 million. The transaction will be
treated as a purchase for accounting purposes and is structured as a tax-free
reorganization to the shareholders. Upon completion of the merger, Access Beyond
shareholders will own approximately 21% of the new company's outstanding shares,
with Hayes shareholders owning the remaining 79%, based on current outstanding
shares. The transaction is subject to completion of due diligence, regulatory
and final shareholder approval from both companies, and is expected to be
completed before the end of 1997. The combined entity is expected to have
revenues of approximately $277 million.

In addition, Hayes Microcomputer Products has signed a commitment letter with a
potential investor, whereby Hayes Microcomputer Products would receive a $30
million cash infusion for approximately 11.7% of the Company. This investment
values Hayes at approximately $255 million prior to the merger with Access
Beyond, and the proceeds will be used for debt reduction and working capital
purposes. If the financing closes prior to the closing of the merger
transaction, the companies have agreed that it will be mutually dilutive.
