corporation (the "Company"), and the persons and entities set forth on Exhibit A
attached hereto.  Such persons and entities shall be referred to hereinafter as

                                    RECITALS

to which the Company will issue shares (the "Shares") of the Company's Common
Stock, par value of $.001 per share ("Common Stock"), to the stockholders of
Nomadic (the "Stockholders") in connection with the merger of a subsidiary of
the Company with and into Nomadic; and

  WHEREAS, the Acquisition Agreement provides that the Stockholders be granted
certain registration rights with respect to the Shares as set forth in the
Agreement;

  NOW, THEREFORE, in consideration of the mutual promises, representations,

Acquisition Agreement, the parties mutually agree as follows:

                                   ARTICLE 1

                                    General

  1.1  DEFINITIONS.  As used in this Agreement the following terms shall have
the following respective meanings:

  "FORM S-3" means such form under the Securities Act as in effect on the date
hereof or any successor registration form under the Securities Act subsequently

security which is issued as) a dividend or other distribution with respect to,
or in exchange for or in replacement of, the Shares.  Notwithstanding the
foregoing, Registrable Securities shall not include (i) any securities sold by a
person to the public either pursuant to a registration statement or Rule 144 or
sold in a private transaction (other than as a result of any transfer pursuant
to Section 2.1(iii) hereof) or (ii) any securities which may be sold by a Holder
under Rule 144 during any ninety (90) day period.

                     REGISTRATION; RESTRICTIONS ON TRANSFER

  2.1  RESTRICTIONS ON TRANSFER.

          (a)  Each Holder agrees not to make any disposition of all or any
portion of the Registrable Securities unless and until the transferee has agreed
in writing for the benefit of the Company to be bound by this Section 2.1,
provided and to the extent such Section is then applicable.  This Section shall
not be applicable if:

               (i)   There is then in effect a registration statement under the
Securities Act covering such proposed disposition and such disposition is made
in accordance with such registration statement; or

               (ii)  (A) Such Holder shall have notified the Company of the 
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (B) if
reasonably requested by the Company, such Holder shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of such Shares under the
Securities Act. It is agreed that the Company will not require opinions of
counsel for transactions made pursuant to Rule 144; or

               (iii) There is a transfer by a Holder which is (A) a partnership 
to its partners in accordance with partnership interests, or (B) to the Holder's
family member or trust for the benefit of an individual Holder, provided the
transferee will be subject to the terms of this Section 2.1 to the same extent
as if he were an original Holder hereunder (it being agreed that the Company
will not require opinions of counsel for such transfers).

          (b)  Each certificate representing the Shares shall (unless otherwise
permitted by the provisions of the Agreement) be stamped or otherwise imprinted
with legends substantially similar to the following (in addition to any legend
required under applicable state securities laws or as provided elsewhere in the
Agreement):

     THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER 
     THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD 
     OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL 
     REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL OR BASED ON 
     OTHER WRITTEN EVIDENCE IN FORM AND SUBSTANCE SATISFACTORY TO THE 
     ISSUER OF THESE

                                       2.
<PAGE>
 
     SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN
     COMPLIANCE THEREWITH.

          (c)  The Company shall be obligated to reissue promptly unlegended
certificates at the request of any Holder thereof if the Holder shall have
obtained an opinion of counsel (which counsel may be counsel to the Company)
reasonably acceptable to the Company to the effect that the securities proposed
to be disposed of may lawfully be so disposed of without registration,
qualification or legend.

          (d)  Any legend endorsed on an instrument pursuant to applicable state
securities laws and the stop-transfer instructions with respect to such
securities shall be removed upon receipt by the Company of an order of the
appropriate blue sky authority authorizing such removal.

     2.2 AUTOMATIC S-3 REGISTRATION.

          2.2.1  The Company will file a Form S-3 registration statement
covering Registrable Securities as provided in the Acquisition Agreement.  In
accordance with the Acquisition Agreement, the Company has agreed to use its
best efforts to cause such registration statement to become effective as soon as
practicable after the release of the Company's financial results for the quarter
ending September 30, 1997, and, in any event, not later than November 15, 1997.
Subject to Section 2.2.2, the Company agrees to keep such registration statement
effective until the earlier of: (i) one (1) year (or such longer period in the
event of a blackout period as described in Section 2.2.2) or (ii) such time as
all shares of Common Stock covered by such Registration Statement are no longer
Registrable Securities.  Except as otherwise provided in this Section 2.2, the
registration statement covered by this Section 2.2 shall be subject to the
provisions of this Agreement.

          2.2.2  Notwithstanding any other provision of this Agreement, the
Holders understand that there may be periods during which the Company's Board of
Directors may determine, in good faith, that it is in the best interest of the
Company and its stockholders to defer disclosure of non-public information until
such information has reached a more advanced stage and that during such periods
sales of Registrable Securities and the effectiveness of any registration
statement covering Registrable Securities may be suspended or delayed.  Each
Holder agrees by acquisition of such Registrable Securities that upon receipt of
any notice from the Company of the development of any non-public information,
such Holder will forthwith discontinue such Holder's disposition of Registrable
Securities pursuant to the registration statement relating to such Registrable
Securities until such Holder's receipt of copies of an appropriately
supplemented or amended prospectus and, if so directed by the Company, such
Holder will use its best efforts to deliver to the Company (at the Company's
expense) all copies, other than permanent file copies then in such Holder's
possession, of the prospectus relating to such Registrable Securities current at
the time of receipt of such notice.  In the event the Company shall give any
such notice, the applicable time period during which a Registration Statement is
to remain effective shall be extended by the number of days during the period
from and including the date of the giving of such notice to and including the
date when each seller of a Registrable Security covered by such registration
statement shall have received the copies of the appropriate supplemented or
amended prospectus.

          2.2.3  A registration filed pursuant to this Section 2.2 will not be
deemed to have been effected unless it has become effective; provided that if,
after it has become effective, the offering of Registrable Securities pursuant
to such registration is interfered with by any stop order, injunction or other
order or requirement of the SEC or other governmental agency or court which
prevents the

                                       3.
<PAGE>
 
successful completion of such offering and which was not caused by the actions
of any Holder, such registration will be deemed not to have been effected.

     2.3 EXPENSES OF REGISTRATION.  All Registration Expenses incurred in
connection with any registration pursuant to Section 2.2 shall be borne by the
Company.  All Selling Expenses incurred in connection with any registrations
hereunder, shall be borne by the holders of the securities so registered pro
rata on the basis of the number of shares so registered.  The Company shall not,
however, be required to pay for expenses of any registration proceeding begun
pursuant to Section 2.2, which has been subsequently withdrawn at the request of
the Holders unless (a) the withdrawal is based upon material adverse information
concerning the Company of which the Holders were not aware at the time of such
request or (b) the Holders of a majority of Registrable Securities agree to
forfeit their right to registration pursuant to Section 2.2 in which event such
right shall be forfeited by all Holders.  If the Holders are required to pay the
Registration Expenses, such expenses shall be borne by the holders of securities
(including Registrable Securities) subject to such registration in proportion to
the number of shares for which registration was sought.  If the Company is
required to pay the Registration Expenses of a withdrawn, then the Holders shall
not forfeit their rights to a registration pursuant to Section 2.2.

     2.4 OBLIGATIONS OF THE COMPANY.  Whenever required to effect the
registration of any Registrable Securities, the Company shall, as expeditiously
as reasonably possible:

          2.4.1  Prepare (and provide the Holders an opportunity to review) and
file with the SEC a registration statement with respect to such Registrable
Securities and use its best efforts to cause such registration statement to
become effective, and, upon the request of the Holders of a majority of the
Registrable Securities registered thereunder, keep such registration statement
effective for up to the earlier of: (i) one (1) year (or such longer period in
the event of a blackout period as described in Section 2.2.2) or (ii) such time
as all shares of Common Stock covered by such registration statement are no
longer Registrable Securities.

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

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

          2.4.4  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

          2.4.5  Notify each Holder covered by such registration statement at
any time when a prospectus relating thereto is required to be delivered under
the Securities Act of the happening of any event as a result of which the
prospectus included in such registration statement, as then in effect, includes
an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances then existing.

                                       4.
<PAGE>
 
     2.5 TERMINATION OF REGISTRATION RIGHTS.  All registration rights granted
under this Article II shall terminate and be of no further force and effect at
such time as the obligations of the Company under Section 2.2 have been
satisfied.

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

     2.7 INDEMNIFICATION.  In the event any Registrable Securities are included
in a registration statement under Section 2.2:

          2.7.1  To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, the partners, officers and directors of each Holder,
and each person, if any, who controls such Holder within the meaning of the
Securities Act or the Securities Exchange Act of 1934, as amended, (the "1934
Act"), against any losses, claims, damages, or liabilities (joint or several) to
which they may become subject under the Securities Act, the 1934 Act or other
federal or state law, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation") by the Company:
(i) any untrue statement or alleged untrue statement of a material fact
contained in such registration statement, including any preliminary prospectus
or final prospectus contained therein or any amendments or supplements thereto,
(ii) the omission or alleged omission to state therein a material fact required
to be stated therein, or necessary to make the statements therein not
misleading, or (iii) any violation or alleged violation by the Company of the
Securities Act, the 1934 Act, any state securities law or any rule or regulation
promulgated under the Securities Act, the 1934 Act or any state securities law
in connection with the offering covered by such registration statement; and the
Company will reimburse each such Holder, partner, officer or director, or
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided however, that the indemnity agreement contained in
this Section 2.7.1 shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Company (which consent shall not be unreasonably withheld),
nor shall the Company be liable in any such case for any such loss, claim,
damage, liability or action to the extent that it arises out of or is based upon
a Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
such Holder, partner, officer, director, underwriter or controlling person of
such Holder.

          2.7.2  To the extent permitted by law, each selling Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers, each person, if any, who controls the Company within the meaning of
the Securities Act, and any other Holder selling securities under such
registration statement or any of such other Holder's partners, directors or
officers or any person who controls such Holder, against any losses, claims,
damages or liabilities (joint or several) to which the Company or any such
director, officer, controlling person, or other such Holder, or partner,
director, officer or controlling person of such other Holder may become subject
under the Securities Act, the 1934 Act or other federal or state law, insofar as
such losses, claims, damages or liabilities (or actions in respect thereto)
arise out of or are based upon any Violation, in each case to the extent (and
only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished by such Holder under an instrument
duly executed by such Holder and stated to be specifically for use in connection
with such registration; and each such Holder will reimburse any legal or other
expenses reasonably incurred by the Company or any such director, officer,
controlling person, underwriter or other Holder, or partner, officer, director
or controlling person of such other Holder in connection with investigating or
defending any such loss, claim, damage, liability or action if it is judicially
determined that there was such a Violation; 

                                       5.
<PAGE>
 
provided, however, that the indemnity agreement contained in this Section 2.7.2
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Holder, which consent shall not be unreasonably withheld; provided further, that
in no event shall any indemnity under this Section 2.7 exceed the net proceeds
from the offering received by such Holder.

          2.7.3  Promptly after receipt by an indemnified party under this
Section 2.7 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 2.7, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding.  The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 2.7, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 2.7.

          2.7.4  If the indemnification provided for in this Section 2.7 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any losses, claims, damages or liabilities referred to herein,
the indemnifying party, in lieu of indemnifying such indemnified party
thereunder, shall to the extent permitted by applicable law contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on the one hand and of the indemnified
party on the other in connection with the Violation(s) that resulted in such
loss, claim, damage or liability, as well as any other relevant equitable
considerations.  The relative fault of the indemnifying party and of the
indemnified party shall be determined by a court of law by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

          2.7.5  The foregoing indemnity agreements of the Company and Holders
are subject to the condition that, insofar as they relate to any Violation made
in a preliminary prospectus but eliminated or remedied in the amended prospectus
on file with the SEC at the time the registration statement in question becomes
effective or the amended prospectus filed with the SEC pursuant to SEC Rule
424(b) (the "Final Prospectus"), such indemnity agreement shall not inure to the
benefit of any indemnified party if a copy of the Final Prospectus was furnished
to the indemnified party, the indemnified party had an obligation to furnish
such Final Prospectus to the person asserting the loss, liability, claim or
damage and the indemnified party did not so furnish the Final Prospectus to the
person asserting the loss, liability, claim or damage at or prior to the time
such action is required by the Securities Act.

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

                                       6.
<PAGE>
 
     2.8 NO ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company
to register Registrable Securities pursuant to this Article II may not be
assigned by a Holder to any transferee of Registrable Securities (other than a
transferee under a transfer made pursuant to Section 2.1(iii) hereof).


                                   ARTICLE 3

the provisions hereof shall inure to the benefit of, and be binding upon, the

     3.5 DELAYS OR OMISSIONS.  It is agreed that no delay or omission to
exercise any right, power, or remedy accruing to any Holder, upon any breach,
default or noncompliance of the Company under this Agreement shall impair any

such breach, default or noncompliance, or any acquiescence therein, or of any
similar breach, default or noncompliance thereafter occurring.  It is further
agreed that any waiver, permit, consent, or approval of any kind or character on
any Holder's part of any breach, default or noncompliance under the Agreement or
any waiver on such Holder's part of any provisions or conditions of this
Agreement must be in writing and shall be effective only to the extent
specifically set forth in such writing.  All remedies, either under this
Agreement, by law, or otherwise afforded to Holders, shall be cumulative and not
alternative.
