                                 PROXY STATEMENT
                    ----------------------------------------

                                  INTRODUCTION

         This  Proxy  Statement  is  being  furnished  in  connection  with  the
solicitation  of  proxies by the Board of  Directors  (the  "Telebit  Board") of
Telebit Corporation (together with its subsidiaries, "Telebit" or the "Company")
to be used at the Special Meeting of shareholders (the "Special  Meeting") to be
held on  Thursday,  October  10,  1996,  at 10:00 a.m.,  local time,  and at any
adjournment  or  postponement  thereof,  at  the  offices  of the  Company,  One
Executive Drive, Chelmsford, Massachusetts 01824.

         The purpose of the Special  Meeting is: (i) to consider and vote upon a
proposal  to approve and adopt the  Agreement  and Plan of  Reorganization  (the
"Merger  Agreement")  dated as of July 21, 1996,  among Cisco  Systems,  Inc., a
California corporation ("Cisco"),  Cobra Acquisition  Corporation,  a California
corporation  and  wholly-owned  subsidiary of Cisco (the "Merger Sub"),  and the
Company  and to approve  consummation  of the merger of Merger Sub with and into
the Company (the "Merger"); (ii) to consider and vote upon a proposal to approve
and adopt the Asset Purchase Agreement (the "Asset Purchase  Agreement") between
Telebit (Newco) Inc., a Delaware corporation  ("Newco"),  and the Company and to
approve  the sale,  and  assumption,  of  substantially  all of the  assets  and
liabilities,  respectively, of Telebit by Newco (the "Asset Sale," and, together
with the Merger, the "Transactions"); (iii) to consider and vote upon a proposal
to adjourn the Special  Meeting in the event there are not  sufficient  votes at
the time of the Special  Meeting to approve and adopt the Merger  Agreement  and
approve the Merger  and/or  approve and adopt the Asset  Purchase  Agreement and
approve the Asset Sale; and (iv) to transact such other business as may properly
come before the Special Meeting or any  postponements  or adjournments  thereof.
See "Information Concerning the Special Meeting--Purpose of Special Meeting."

         Pursuant to the Merger  Agreement,  a copy of which is attached to this
Proxy  Statement  as  Appendix  A, the  Merger  Sub will merge with and into the
Company, with the Company remaining as the surviving corporation.  As more fully
described  herein  under "The  Merger" the result of the Merger will be that the
Company  will  become a  wholly-owned  subsidiary  of Cisco and each  issued and
outstanding  share of common stock,  no par value per share, of the Company (the
"Telebit  Common Stock"),  will be converted into the right to receive  thirteen
dollars and thirty-five  cents ($13.35) in cash,  without  interest (the "Merger
Consideration").  The  obligations  of Cisco and  Merger Sub to  consummate  the
Merger  are  subject  to  certain  conditions,  including,  without  limitation,
consummation of the Asset Sale. See "The Merger."

         Pursuant to the Asset Purchase  Agreement,  a copy of which is attached
to this Proxy  Statement  as  Appendix B,  substantially  all of the assets (the
"Purchased Assets") and liabilities (the "Assumed  Liabilities") of the Company,
other than the Company's Modem ISDN Channel  Aggregation  ("MICA") digital modem
technology (the "MICA  Technology"),  the trademark MICA (the "MICA  trademark,"
and,  collectively  with the MICA  Technology,  the  "MICA  Assets"),  all other
Telebit  patents and patent  applications  and $3.5 million in cash (all as more
fully described in the Asset Purchase Agreement), will be sold to and assumed by
Newco in consideration for $31.5 million  aggregate  principal amount of Secured
Subordinated Promissory Notes due 2001 of Newco (the "Notes").  Newco was formed
by 







James D. Norrod,  President and Chief Executive  Officer of Telebit for the sole
purpose of affecting the Asset Sale. As of September 11, 1996 Mr. Norrod was the
sole stockholder and sole director of Newco.

         The  rights  of  Telebit  as  holder  of the Notes are set forth in the
Preferred Stock Purchase and Noteholder  Rights  Agreement (the "Preferred Stock
Purchase and  Noteholder  Rights  Agreement")  dated as of July 21, 1996 between
Newco and the  Company,  a copy of which is attached to this Proxy  Statement as
Appendix  C.  The  Notes,  as more  fully  described  herein  under  "The  Asset
Transactions--Related  Agreements--The  Preferred  Stock Purchase and Noteholder
Rights Agreement--The Notes," will be subordinated secured obligations of Newco.
The Notes will be  subordinated  to all Senior Debt (as defined).  Further,  the
Notes will be secured by and  entitled to the  benefits of a Security  Agreement
(the  "Security  Agreement"),  pursuant  to which  Newco  will  grant  Telebit a
security  interest  in  substantially  all of Newco's  assets  and any  proceeds
thereof to secure the performance of Newco's  obligations  under the Notes.  See
"The Asset  Transactions--Related  Agreements--The  Preferred Stock Purchase and
Noteholder Rights Agreement--The Notes."

         The Preferred Stock Purchase and Noteholder  Rights  Agreement  further
provides  for the sale by Newco and the  purchase by Telebit of 3,500  shares of
Class A Redeemable  Preferred  Stock,  $.01 par value per share (the  "Preferred
Stock"),  for an  aggregate  purchase  price of $3.5  million.  See  "The  Asset
Transactions--Related  Agreements--The  Preferred  Stock Purchase and Noteholder
Rights Agreement--The Preferred Stock."

         In addition to the foregoing,  Newco and Telebit, as a condition to the
obligation of Newco to close the Asset Sale, will enter into: (i) a MICA License
Agreement  (the  "MICA  Agreement")  whereby  the  Company  will  grant  Newco a
worldwide,  non-exclusive,  non-transferable,   non-sublicensable,  royalty-free
(during the initial  3-year term)  license to use the MICA  Technology in object
code form only and only as  embedded  in  products  of Newco to which  Newco has
added  substantial  value;  (ii) an Analog Patent License Agreement (the "Analog
Agreement") whereby the Company will grant to Newco a worldwide,  non-exclusive,
sublicensable,  royalty-free  license to research,  develop,  manufacture,  have
manufactured,  use, market,  import,  sell and distribute  products covered by a
valid  claim  of an  issued  patent  or a  pending  claim  of a  pending  patent
application  with  respect to certain  patent  rights;  and (iii) an ADSL Patent
License Agreement (the "ADSL Agreement") whereby the Company will grant to Newco
a  worldwide,  non-exclusive,  non-sublicensable,  non-transferable  license  to
research, develop, manufacture, have manufactured, use, market, import, sell and
distribute  licensee  products covered by a valid claim of an issued patent or a
pending claim of a pending  patent  application  with respect to certain  patent
rights relating to asymmetric digital subscriber line ("ADSL")  technology.  See
"The Asset Transactions--Related Agreements."

         Finally,  Newco has entered into an  Employment  Agreement  dated as of
July 21,  1996 with James D.  Norrod (the  "Employment  Agreement")  whereby Mr.
Norrod has agreed to serve as Chief Executive  Officer and President of Newco in
consideration  for salary and bonus,  effective as of the effective  time of the
Merger. The term of the Employment  Agreement is three (3) years. The Employment
Agreement is terminable by Mr. Norrod upon thirty (30) days notice and by Newco,
with or without notice, subject to, under certain circumstances,  the payment of
certain    severance    benefits.    See   "The   Asset    Transactions--Related
Agreements--Employment  Agreement of James D.  Norrod." The Asset Sale,  and the
transactions  contemplated by the Preferred Stock Purchase and Noteholder Rights
Agreement,  the MICA Agreement, the Analog Agreement, the ADSL Agreement and the
Employment  Agreement  are  collectively   referred  to  herein  as  the  "Asset
Transactions."


                                      -2-



         The  Board  of  Directors  of  the  Company,  based  on  the  unanimous
recommendation  of a Special  Committee of the Board of Directors  (the "Special
Committee")  consisting of directors  who are not employees of the Company,  has
approved the Merger  Agreement and  consummation  of the Merger by the unanimous
vote of all non-interested directors and believes that the Merger is fair and in
the best interests of the Company and its  shareholders and recommends a vote by
the  shareholders  of the  Company  FOR  approval  and  adoption  of the  Merger
Agreement and approval of  consummation  of the Merger.  The Board of Directors,
based  on the  unanimous  recommendation  of the  Special  Committee,  also  has
approved the Asset Purchase  Agreement and consummation of the Asset Sale by the
unanimous vote of all non-interested  directors and believes that the Asset Sale
is fair  and in the best  interests  of the  Company  and its  shareholders  and
recommends a vote by the  shareholders  of the Company FOR approval and adoption
of the Asset Purchase  Agreement and approval of consummation of the Asset Sale.

Directors" and "The  Transactions--Reasons for the Transactions;  Recommendation
of the Board of Directors."

Stock  outstanding  on September  11, 1996 (the  "Record  Date") is required for
approval and adoption of the Merger  Agreement and approval of  consummation  of
the Merger,  and for approval and adoption of the Asset  Purchase  Agreement and
approval of  consummation of the Asset Sale. Only holders of record of shares of
Telebit Common Stock on the Record Date are entitled to notice of and to vote at

THE  MERGER  AND (II) THE  PROPOSAL  TO  APPROVE  AND ADOPT  THE ASSET  PURCHASE
AGREEMENT  AND  APPROVE   CONSUMMATION  OF  THE  ASSET  SALE.  See  "Information
Concerning the Special Meeting--Quorum; Abstentions and Broker "Non-Votes."

customers to build: (i) dial-up local area network ("LAN")  inter-networks  that
provide  remote  offices,  telecommuters  and mobile  computer  users  access to
corporate  networks;  (ii) remote LAN access networks that provide access to the
Internet; and (iii) mission critical wide area network ("WAN") access facilities
that  provide  LAN or host  access over the public  switched  telephone  network
("PSTN").  The Company's  products consist  primarily of the NetBlazer family of
dial-up  access routers and modem  products  consisting  primarily of high-speed
dial-up modems and modem network  management  systems.  The Company  markets its
products  worldwide  through  distributors,  value added resellers  ("VARs") and
service providers. The Company also sells its modem products to certain original
equipment manufacturers ("OEMs").

         The Company's  strategy is to capitalize on several  significant trends
in the data communications  industry,  including: (i) the growing demand for LAN
to LAN  connectivity  to provide  affordable  links between  business  partners,
branch  offices  and  corporate  LANs over the WAN;  (ii) the need for  seamless
internetworking  and   interoperability  of  disparate  computers  and  computer
networks; (iii) the growing demand for client to LAN connectivity resulting from
the growth in sales of laptop and notebook size  computers to mobile workers and
telecommuters;  (iv) the continuing  evolution of high-speed  analog and digital
technology  enabling  dial-up  networking  solutions;   and  (v)  the  need  for
high-density, lower cost, central site remote network access solutions.

         As part of this strategy the Company seeks to identify  remote  network
access market segments  requiring high  performance  solutions and to develop or
license products targeting these markets.  During the third quarter of 1995, the
Company  identified  a market need for  high-density,  lower-cost,  central site
remote  network access  solutions.  In response to this market need, the Company
undertook the development of its MICA  Technology.  The MICA Technology is being
developed to allow organizations to eliminate the need for multiple analog lines
and  corresponding   analog  modems  and  replace  this   functionality  with  a
high-density  ISA  card-based  digital  modem  solution  using a  single  common
high-speed  digital line with the ability to dynamically  configure  channels to
handle both digital and digitized analog transmissions. See "Certain Information
Regarding Telebit."

         Telebit  was  incorporated  in  California  in  July  1982.   Telebit's
executive offices are located at One Executive Drive, Chelmsford,  Massachusetts
01824, and its telephone number at that location is (508) 441-2181.

and to approve  consummation  of the Merger;  (ii) to  consider  and vote upon a
proposal  to  approve  and adopt the Asset  Purchase  Agreement 


                                      -9-


and to approve  consummation of the Asset Sale; and (iii) to transact such other
business as may properly come before the Special Meeting or any postponements or

THE TRANSACTIONS

         Reasons for the Transactions.  The Telebit Board considered a number of
factors in determining to recommend approval of the Transactions, including: (i)
the increased  competition,  consolidation and rapid technological change in the
networking industry making it difficult to compete effectively;  (ii) the recent
financial performance of Telebit;  (iii) the current financial market conditions
and the historical market information  concerning Telebit Common Stock; (iv) the
significant  premium of the all-cash 


                                      -10-



Merger  Consideration  over the recent price of Telebit  Common  Stock;  (v) the
current market conditions for networking stocks generally; and (vi) the opinions
of the financial advisor of Telebit that the consideration to be received by (a)
holders of Telebit  Common Stock  pursuant to the Merger is fair to such holders
from a  financial  point of view and (b)  Telebit  pursuant to the Asset Sale is
fair   to   Telebit    from   a    financial    point   of   view.    See   "The
Transactions--Background of the Transactions";  "--Reasons for the Transactions;
Recommendation  of the  Board  of  Directors"  and  "Opinions  of the  Financial
Advisor."

         Recommendation of the Board of Directors.  The Telebit Board,  based on
the unanimous  recommendation of the Special Committee,  has approved the Merger
Agreement  and  consummation  of  the  Merger  by  the  unanimous  vote  of  all
non-interested  directors  and believes  that the Merger is fair and in the best
interests  of Telebit  and its  shareholders.  Michael K.  Ballard,  who will be
employed by Cisco  following  consummation of the  Transactions,  abstained from
voting on the proposal to approve the Merger  Agreement and  consummation of the
Merger. The Telebit Board, based on the unanimous  recommendation of the Special
Committee,  also has approved the Asset Purchase  Agreement and  consummation of
the  Asset  Sale by the  unanimous  vote  of all  non-interested  directors  and
believes that the Asset Purchase Agreement and consummation of the Asset Sale is
fair and in the best interest of Telebit and its shareholders.  Mr. Norrod,  the
President and Chief  Executive  Officer of Telebit and President,  sole director
and sole stockholder of Newco,  abstained from voting on the proposal to approve
the Asset  Purchase  Agreement  and  consummation  of the Asset Sale.  The Board
recommends a vote by the  shareholders  of the Company FOR approval and adoption
of the Merger  Agreement  and  approval  of  consummation  of the Merger and FOR
approval  and  adoption  of  the  Asset  Purchase   Agreement  and  approval  of
consummation  of  the  Asset  Sale.  See  "Information  Concerning  the  Special
Meeting--Recommendation    of   the    Board    of    Directors";    and    "The
Transactions--Reasons  for thE  Transactions;  Recommendation  of the  Board  of
Directors."


THE MERGER

         General.  Cisco,  Merger Sub and Telebit  have  entered into the Merger
Agreement, whereby Merger Sub will be merged with and into Telebit, resulting in
Telebit becoming a wholly-owned subsidiary of Cisco. See "The Merger."

         Conversion  of Shares  and Vested  Options.  Upon  consummation  of the
Merger,   each  then   outstanding   share  of  Telebit  Common  Stock  will  be
automatically  converted into the right to receive the Merger Consideration.  In
addition,  upon consummation of the Merger,  each then outstanding  option under
Telebit's stock option plans shall,  to the extent  exercisable at such time for
vested shares of Telebit  Common Stock be canceled,  and the holder of each such
canceled  option  shall be  entitled  to receive a cash sum per vested  share of
Telebit Common Stock equal to the Merger  Consideration  less the exercise price
per share of Telebit Common Stock in effect under that option  immediately prior
to  consummation  of the Merger.  As of the Record Date,  options to purchase an
aggregate of 1,283,307  vested shares of Telebit Common Stock were  outstanding.
In addition,  the vesting of options to purchase an aggregate of 183,183  shares
of Telebit Common Stock will be accelerated in connection  with  consummation of
the Merger. See "The Merger--Conversion of Shares and Vested Options."

         Treatment of Unvested Employee Stock Options.  Each option  outstanding
upon  consummation  of the Merger  under  Telebit's  1995 Stock Option Plan (the
"1995 Plan") held by a Telebit  employee who will continue his or her employment
with Telebit following  consummation of the Merger shall, to the extent that the
option is not at such time  exercisable  for  vested  shares of  Telebit  Common
Stock, be assumed by Cisco


                                      -11-


and shall  automatically  be converted  into an option to purchase the number of
shares of the common stock of Cisco, $.01 par value per share (the "Cisco Common
Stock"),  determined  by  multiplying  the number of unvested  shares of Telebit
Common Stock subject to that option  immediately  prior to  consummation  of the
Merger by a factor obtained by dividing the Merger  Consideration by the average
of the closing selling price per share of Cisco Common Stock as quoted on Nasdaq
for each of the five trading days ending with the second trading day immediately
preceding  the date of the Special  Meeting,  rounded down to the nearest  whole
number of shares of Cisco Common Stock, at an exercise price per share,  rounded
up to the  nearest  whole  cent,  equal to the  exercise  price per share of the
Telebit option at the time of consummation of the Merger  multiplied by a factor
obtained by dividing the average of the closing selling price per share of Cisco
Common  Stock as  quoted  on Nasdaq  for each of each of the five  trading  days
ending with the second day immediately preceding the date of the Special Meeting
by the Merger Consideration. The other terms of the options under Telebit's 1995
Plan assumed by Cisco, including vesting schedules, will remain unchanged. As of
the Record Date,  107,077 options were outstanding under Telebit's 1995 Plan and
are expected to be assumed by Cisco which,  assuming a price of $_____ per share
of the  common  stock of Cisco,  $.01 par value per  share  (the  "Cisco  Common
Stock"),  will be exercisable for  approximately  _____________  shares of Cisco
Common Stock.  Following the  effectiveness  of the Merger,  with respect to any
Telebit option assumed by Cisco, Cisco will issue to each holder of such assumed
option a document  evidencing the assumption of the option by Cisco. Each option
outstanding  upon  consummation of the Merger under Telebit's 1995 Plan which is
held by an employee of Telebit who will become an employee of Newco  immediately
following consummation of the Merger shall, to the extent that the option is not
at such time  exercisable  for vested shares of Telebit Common Stock, be treated
in the manner determined by Newco. All other options  outstanding at the time of
consummation  of the Merger under  Telebit's  stock  option plans shall,  to the
extent not  exercisable  for vested shares of Telebit Common Stock at that time,
terminate and cease to be outstanding.  As of the Record Date, there shall be no
such options to be so terminated.  Outstanding purchase rights under the Telebit
1990 Employee Stock Purchase Plan shall be exercised  prior to  consummation  of
the Merger,  and shares so  purchased,  shall  automatically  be converted  upon
consummation  of the Merger into the right to receive the Merger  Consideration.
See "The Merger--Treatment of Employee Stock Options."

         Exchange of  Certificates.  Following  consummation  of the  Merger,  a
letter of transmittal with instructions for completion thereof will be mailed to
each holder of record of Telebit Common Stock and stock option  agreements  with
respect  to vested  Telebit  options  ("Vested  Option  Agreements")  for use in
exchanging  Telebit Common Stock  certificates and Vested Option  Agreements for
the Merger  Consideration.  HOLDERS OF TELEBIT  COMMON  STOCK AND VESTED  OPTION
AGREEMENTS  SHOULD  NOT  SUBMIT  THEIR  STOCK   CERTIFICATES  OR  VESTED  OPTION
AGREEMENTS FOR EXCHANGE  UNTIL THEY HAVE RECEIVED THE LETTER OF TRANSMITTAL  AND
INSTRUCTIONS. See "The Merger--Exchange of Certificates."

         Operations Following the Merger.  Following the Merger,  subject to the
Asset  Transactions,  Telebit will  continue its  operations  as a  wholly-owned
subsidiary of Cisco. See "The Merger--Operations Following the Merger."

The Merger Agreement

         Representations,   Warranties  and  Covenants.   The  Merger  Agreement
contains  various  representations  and  warranties  of the  parties,  including
representations  by  Cisco,  Telebit  and  Merger  Sub  as to  their  respective
organization  and corporate  power and their  authority to enter into the Merger
Agreement and to  consummate  the Merger.  Telebit  covenanted  that,  until the
termination of the Merger Agreement or consummation of the Merger,  it will take
reasonable efforts to meet the product



                                      -12-


development schedule for its MICA-based products,  it will carry on its business
in the  ordinary  course and  attempt  to  preserve  its  present  business  and
relationships  with  customers,  suppliers and others,  it will not take certain
actions without Cisco's consent,  and it will use its best efforts to consummate
the Merger. See "The Merger--The Merger  Agreement--Representations,  Warranties
and Covenants."

         No  Solicitation  of  Transactions.  Telebit  has  further  agreed that
Telebit and its  subsidiaries  and the officers,  directors,  employees or other
agents of Telebit and its  subsidiaries  will not,  directly or indirectly:  (i)
take any action to solicit,  initiate or  encourage  any  Takeover  Proposal (as
defined) or (ii)  subject to the terms of the  immediately  following  sentence,
engage in negotiations with, or disclose any nonpublic  information  relating to
Telebit or any of it subsidiaries to, or afford access to the properties,  books
or records of Telebit or any of its subsidiaries to, any person that has advised
Telebit  that  it may be  considering  making,  or that  has  made,  a  Takeover
Proposal; provided, that the foregoing shall not prohibit the Telebit Board from
taking and  disclosing  to Telebit's  shareholders  a position with respect to a
tender offer  pursuant to Rules 14d-9 and 14e-2  promulgated  under the Exchange
Act.  Notwithstanding  the  immediately  preceding  sentence,  if an unsolicited
Takeover Proposal, or an unsolicited written expression of interest that Telebit
reasonably  expects to lead to a Takeover  Proposal,  shall be  received  by the
Telebit  Board,  then,  to the extent the Telebit  Board  believes in good faith
(after  consultation  with its financial  advisor)  that such Takeover  Proposal
would,  if  consummated,  result in a  transaction  more  favorable to Telebit's
shareholders  from a financial point of view than the transactions  contemplated
by the  Merger  Agreement  (any  such more  favorable  Takeover  Proposal  being
referred to herein as a "Superior Proposal") and the Telebit Board determines in
good faith  after  consultation  with  outside  legal  counsel  that it would be
inconsistent with the Board's fiduciary duties to shareholders  under applicable
law,  Telebit  and  its  officers,  directors,  employees,  investment  bankers,
financial advisors, attorneys, accountants and other representatives retained by
it may furnish in connection  therewith  information and take such other actions
as are consistent with the fiduciary  obligations of the Telebit Board, and such
actions shall not be considered a breach of the Merger Agreement; provided, that
in each such event Telebit  notifies Cisco of such  determination by the Telebit
Board and provides Cisco with a true and complete copy of the Superior  Proposal
received  from such third party,  if the Superior  Proposal is in writing,  or a
complete  written summary thereof,  if it is not in writing,  and provides Cisco
with all documents containing or referring to non-public  information of Telebit
that are supplied to such third party; provided,  further, that: (i) the Telebit
Board has determined, with the advice of Telebit's investment bankers, that such
third  party  is  capable  of  making  a  Superior  Proposal  upon  satisfactory
completion of such third party's review of the information  supplied by Telebit;
(ii) the third  party has stated  that it  intends to make a Superior  Proposal;
(iii) Telebit may not provide any non-public information to any such third party
if it has not prior to the date thereof  provided such  information  to Cisco or
Cisco's  representatives;  and (iv) Telebit provides such non-public information
pursuant to a non-disclosure agreement substantially the same as or otherwise at
least as restrictive on such third party as the Confidentiality  Agreement is on
Cisco;  provided,  however,  that Telebit shall not, and shall not permit any of
its  officers,  directors,  employees  or other  representatives  to agree to or
endorse any Takeover  Proposal  unless Telebit shall have  terminated the Merger
Agreement and paid to Cisco all amounts  payable to Cisco pursuant to the Merger
Agreement.  Telebit will  promptly  notify  Cisco after  receipt of any Takeover
Proposal or any notice that any person is considering making a Takeover Proposal
or any  request  for  non-public  information  relating to Telebit or any of its
subsidiaries or for access to the properties, books or records of Telebit or any
of its  subsidiaries  by any  person  that has  advised  Telebit  that it may be
considering  making,  or that has made, a Takeover  Proposal and will keep Cisco
fully informed of the status and details of any such Takeover  Proposal  notice,
request  or any  correspondence  or  communications  related  thereto  and shall
provide  Cisco with a true and complete copy of such  Takeover  Proposal  notice
request  or  correspondence  or  communications  related  thereto,  if  it is in
writing,  or a complete  written summary  thereof,  if it is not in writing.  In
addition,  under certain circumstances the Cisco Option (as defined below) would
then become exercisable.  See "The Merger--The Merger Agreement--No Solicitation
of


                                      -13-


Transactions,"   "--Fees  and  Expenses;   Termination   Fee,"  and   "--Related
Agreements--Stock Option Agreement."

         Conditions  to the  Merger.  In addition  to the  requirement  that the
requisite  approval of Telebit  shareholders  be received,  consummation  of the
Merger is subject to a number of other  conditions  that,  if not  satisfied  or
waived,  may cause the Merger not to be consummated and the Merger  Agreement to
be terminated.  Each party's  obligation to consummate the Merger is conditioned
on,  among other  things,  consummation  of the Asset Sale,  the accuracy of the
other party's  representations,  the other party's performance of its covenants,
and the absence of legal action  preventing  consummation of the Merger.  At any
time prior to the  Merger,  either  party may waive  compliance  with any of the
agreements or satisfaction of any of the conditions in the Merger Agreement.
See "The Merger--The Merger Agreement--Conditions to the Merger."

         Closing. As promptly as practicable after the satisfaction or waiver of
the  conditions set forth in the Merger  Agreement,  Merger Sub and Telebit will
file an  Agreement  of Merger with the  Secretary  of State of  California.  The
Merger will become  effective  upon such filing (the  "Effective  Time").  It is
anticipated  that,  assuming all conditions are met, the Merger will occur and a
closing will be held on or before October 11, 1996. See "The Merger--The  Merger
Agreement--Closing."

         Termination,  Amendments  and  Waivers.  The  Merger  Agreement  may be
terminated  at any time prior to the  Effective  Time,  whether  before or after
approval by the Telebit shareholders:  (i) by the mutual consent duly authorized
by the Board of Directors of Cisco and Telebit;  (ii) by either Cisco or Telebit
if, without fault of the terminating  party, the Merger is not consummated on or
before  December  31,  1996 (or such later date that the parties may agree to in
writing);  (iii) by Cisco, if (a) Telebit  breaches any of its  representations,
warranties  or  obligations  under the Merger  Agreement  and such breach is not
cured within ten (10) business  days of receipt by Telebit of written  notice of
such  breach;  (b) the  Telebit  Board  shall have  withdrawn  or  modified  its
recommendation  of the Merger  Agreement  or the  Merger in a manner  adverse to
Cisco,  or shall have  resolved to do any of the foregoing or (c) for any reason
Telebit fails to call and hold the Special Meeting by November 15, 1996; (iv) by
Telebit, if Cisco breaches any of its respective representations,  warranties or
obligations  under the Merger  Agreement and such breach is not cured within ten
(10) days following  receipt by Cisco of written  notice of such breach;  (v) by
either Cisco or Telebit if a Trigger Event (as defined) or Takeover Proposal (as
defined)  shall have  occurred and the Telebit  Board in  connection  therewith,
after  consultation  with its legal counsel,  withdraws or modifies its approval
and recommendation of the Merger Agreement and the Merger in a manner adverse to
Cisco after  determining  that to cause Telebit to proceed with the Merger would
not be consistent with the Telebit Board's fiduciary duty to the shareholders of
Telebit;  or (vi) by either Cisco or Telebit if (x) any permanent  injunction or
other order of a court or other competent authority  preventing  consummation of
the Merger becomes final and  nonappealable or (y) any required  approval of the
shareholders  of Telebit is not  obtained by reason of the failure to obtain the
required vote upon a vote held at a duly held meeting of  shareholders or at any
adjournment thereof.

         The Merger  Agreement  may be amended by Cisco and  Telebit at any time
before or after approval by the Telebit  shareholders,  except that,  after such
approval,  no amendment  may be made which:  (i) alters or changes the amount or
kind of  consideration  to be received  upon  conversion  of the Telebit  Common
Stock;  (ii) alters or changes any term of the Articles of  Incorporation of the
surviving  corporation to be effected by the Merger;  or (iii) alters or changes
any of the terms and  conditions of the Merger  Agreement if such  alteration or
change would adversely affect the holders of Telebit or Merger Sub Common Stock.


                                      -14-


         At any time  prior to the  Effective  Time,  either of Cisco or Telebit
may,  to  the  extent  legally  allowed,  by  execution  of an  instrument  duly
authorized  in writing  signed on behalf of such party:  (i) extend the time for
the  performance of any of the  obligations or acts of the other party set forth
in the Merger Agreement;  (ii) waive any inaccuracies in the representations and
warranties  made  to such  party  in the  Merger  Agreement  or in any  document
delivered pursuant to the Merger Agreement;  and (iii) waive compliance with any
of the  agreements or conditions  for the benefit of such party under the Merger
Agreement.  See "The Merger--The Merger  Agreement--Termination,  Amendments and
Waivers."

         Fees and  Expenses;  Termination  Fee.  Whether  or not the  Merger  is
consummated,  all costs and  expenses  incurred  in  connection  with the Merger
Agreement  and the  Merger  will be paid by the  party  incurring  the  expense.
Notwithstanding the foregoing, if, under certain circumstances, Cisco or Telebit
terminates the Merger  Agreement,  Telebit must promptly pay to Cisco all of the
fees and  out-of-pocket  costs  (up to an  aggregate  amount  not to  exceed  $1
million)  incurred  by Cisco in  connection  with the Merger  Agreement  and the
Merger,  and, under certain  circumstances,  a cash sum of up to $8 million.  In
addition,  if Telebit terminates the Merger Agreement as a result of a breach by
Cisco of the representations,  warranties,  or obligations of Cisco contained in
the Merger  Agreement which breach remains  uncured,  Cisco must promptly pay to
Telebit all of the fees and  out-of-pocket  costs (up to an aggregate amount not
to  exceed $1  million)  incurred  by  Telebit  in  connection  with the  Merger
Agreement and the Merger.  In addition,  under certain  circumstances  the Cisco
Option   would   then   become   exercisable.   See  "The   Merger--The   Merger
Agreement--Fees and Expenses;  Termination Fee" and "--Related Agreements--Stock
Option Agreement."

         Indemnification  and Insurance.  Cisco has agreed that,  from and after
the Effective Time,  Cisco will, and will cause Telebit to indemnify the present
and former officers, directors,  employees and agents of Telebit against certain
liabilities,  including,  without  limitation,  liabilities  arising  out  of or
pertaining to the transactions contemplated by the Merger Agreement.

         For four years after the Effective  Time,  Cisco will either (i) at all
times  maintain  at least  $500  million  in  cash,  marketable  securities  and
unrestricted lines of credit to be available to indemnify the present and former
officers,   directors,   employees  and  agents  of  Telebit   against   certain
liabilities; or (ii) cause Telebit to use its best efforts to maintain in effect
Telebit's current policies for directors and officers' liability  insurance,  or
policies  substantially  equivalent to the policies then  maintained by Telebit.
See "The Merger--The Merger Agreement--Indemnification and Insurance."

         Deregistration  of Telebit Common Stock.  Following the Effective Time,
the  shares of  Telebit  Common  Stock  will  cease to be  registered  under the
Exchange   Act   and   will   cease   to   be   publicly   traded.    See   "The
Merger--Deregistration of Telebit Common Stock."

Related Agreements

         Voting Agreements.  In connection with the Merger, certain shareholders
of Telebit have entered  into voting  agreements  dated as of July 21, 1996 (the
"Voting  Agreements")  with Cisco. The terms of such Voting  Agreements  provide
that each of such  shareholders  will vote all  shares of Telebit  Common  Stock
beneficially  owned by such  shareholders in favor of the approval of the Merger
Agreement and  consummation  of the Merger and against any competing  proposals.
The Voting  Agreements  are  accompanied  by  irrevocable  proxies  whereby  the
shareholders  of Telebit  provide to Cisco the right to vote their shares on the
proposals relating to the Merger Agreement and the Merger at the Special Meeting
and  any  competing  proposal  at a  Telebit  stockholder  meeting.  Holders  of
approximately  7.2%


                                      -15-


(exclusive of any shares  issuable upon the exercise of any options held by such
holders) of the shares of Telebit  Common Stock  entitled to vote at the Special
Meeting have entered into such Voting  Agreements and irrevocable  proxies.  See
"The Merger--Related Agreements--Voting Agreements."

         Stock  Option  Agreement.  Cisco and Telebit  have entered into a Stock
Option  Agreement,  dated as of July 21,  1996 (the "Stock  Option  Agreement"),
pursuant to which Cisco has the right, under certain  circumstances,  to acquire
up to  2,071,000  shares of  authorized  and unissued  Telebit  Common Stock (or
approximately  fifteen  percent (15%) of the  outstanding  Telebit  Common Stock
prior to such issuance) at a price per share of $13.35 (the "Cisco Option"). See
"The Merger--Related Agreements--Stock Option Agreement."

         Interests  of  Certain  Persons  in  the  Merger.  In  considering  the
recommendation of the Telebit Board with respect to the Merger,  shareholders of
Telebit  should be aware that  certain  officers  and  directors of Telebit have
interests  in  the  Merger,  that  present  them  with  potential  conflicts  of
interests. See "The Merger--Interests of Certain Persons in the Merger."

         Certain Federal Income Tax  Considerations.  As a result of the Merger,
holders of Telebit Common Stock  generally  will recognize  capital gain or loss
equal to the  difference  between  the amount of cash  received in the Merger or
pursuant to the exercise of dissenter's rights and the adjusted tax basis of the
Telebit  Common  Stock  exchanged  therefor.  Such  capital gain or loss will be
long-term capital gain or loss if the holding period of the Telebit Common Stock
is more than one year.  TELEBIT  SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS  AS TO THE  SPECIFIC  TAX  CONSEQUENCES  OF THE MERGER,  INCLUDING  THE
APPLICABLE  FEDERAL,  STATE,  LOCAL AND FOREIGN TAX  CONSEQUENCES TO THEM OF THE
MERGER. See "The Merger--Certain Federal Income Tax Considerations."

         Accounting Treatment.  The Merger is expected to be accounted for under
the  purchase  method of  accounting,  with  Cisco as the  acquiring  party,  in
accordance with generally  accepted  accounting  principles.  Under the purchase
method of accounting,  the purchase price of Telebit,  including direct costs of
the Merger,  will be allocated to the assets  acquired and  liabilities  assumed
based upon their  estimated  fair values,  with any excess of the purchase price
over the estimated fair value of net assets acquired being recorded as goodwill.
See "The Merger--Accounting Treatment."

the  principal  amount  of  $31.5  million  and the  assumption  of the  Assumed
Liabilities.  In connection,  and  simultaneously,  with the Asset Sale, Telebit

actions, and it will use its best efforts to consummate the Asset Sale. See "The

and Covenants."

         Employees, Offers of Employment, Employee Benefit Plans. On or prior to
consummation  of  the  Asset  Sale,  Newco  may  at its  sole  discretion  offer
employment to employees of the Business who have not been offered  employment by
Cisco pursuant to the Merger Agreement.  See "The Asset  Transactions--The Asset
Purchase Agreement--Employees, Offers of Employment, Employee Benefit Plans."

         Conditions to the Asset Sale. In addition to the  requirement  that the
requisite  approval of Telebit  shareholders  be received,  consummation  of the
Asset Sale is subject to a number of other  conditions that, if not satisfied or
waived,  may cause the Asset Sale not to be  consummated  and the Asset Purchase
Agreement to be terminated. Each party's obligation to consummate the Asset Sale
is  conditioned  on,  among other  things,  the  accuracy  of the other  party's
representations,  the other party's  performance  of its  obligations  under the
Asset  Purchase   Agreement,   and  the  absence  of  legal  action   preventing
consummation of the Asset Sale. See "The Asset  Transactions--The Asset Purchase
Agreement--Conditions to the Asset Sale."

         Indemnification.  Newco has agreed, for a period of ten (10) years from
consummation of the Asset Sale, to indemnify and hold harmless  Telebit,  any of
its  affiliates  and the directors,  officers,  employees,  counsel or agents of
Telebit or any such affiliate from and against certain  liabilities,  including,

Assets, the Assumed Liabilities, the Asset Sale or the Business.

Transactions--The Asset Purchase Agreement--Indemnification."

         Termination;  Costs  and  Expenses;  Amendment  and  Waiver.  The Asset
Purchase  Agreement may be terminated at any time prior to  consummation  of the
Asset Sale:  (i) by the mutual written  agreement of Telebit and Newco;  (ii) by
either Telebit or Newco,  if, without fault of the terminating  party, the Asset
Sale shall not have been  consummated on or before  December 31, 1996;  (iii) by
either  Telebit  or Newco if there  shall be any law or  regulation  that  makes
consummation   of  the  Asset  Sale  illegal  or  otherwise   prohibited  or  if
consummation  of the Asset Sale would  violate any  nonappealable  final  order,
decree or judgment of any court or governmental body of competent  jurisdiction;
or (iv) by Telebit or Newco if the Merger  Agreement is  terminated  pursuant to
the provisions contained therein. If the Asset Purchase Agreement is terminated,
such termination  shall be without liability of either party to the other party;
provided  that if such  termination  shall  result from the  willful  failure of
either party to fulfill a condition to the performance of the obligations of the
other party or to perform a covenant of the Asset  Purchase  Agreement or from a
willful breach by either party to the Asset Purchase Agreement, such party shall
be fully  liable for any and all losses  incurred or suffered by the other party
as a result of such failure or breach.  At any time prior to consummation of the
Asset Sale,  any  provision of the Asset  Purchase  Agreement  may be amended or
waived by the execution of a written  amendment or waiver signed by both parties
or by the party  against  whom the waiver is to be effected,  respectively.  See
"The Asset  Transactions--The Asset Purchase  Agreement--Termination;  Costs and
Expenses; Amendment and Waiver."

royalty-free,  worldwide,  non-exclusive,  non-transferable,   non-sublicensable
(except  under  certain  conditions  and  restrictions)  license to use the MICA
digital modem  technology in object code only (the "Licensed  Technology").  The

non-transferable license to research, develop,  manufacture,  have manufactured,
use, market, import, sell and distribute Newco products covered by a valid claim
of an issued  patent or a pending  claim of a pending  patent  application  with
respect to all  inventions  and  discoveries  claimed in the  patents and patent

See "The Asset Transactions--Related Agreements--ADSL Agreement."

         Analog Agreement.

         Under the Analog Agreement, Telebit will grant to Newco a royalty-free,
worldwide,   non-exclusive,   sublicensable  (subject  to  certain  conditions),
non-transferable license to research, develop,  manufacture,  have manufactured,
use, market, import, sell and distribute Newco products covered by a valid claim
of an issued  patent or a pending  claim of a pending  patent  application  with

         Employment Agreement of James D. Norrod.

         James D. Norrod has entered into an  Employment  Agreement  with Newco,
whereby Mr. Norrod has agreed to serve as President and Chief Executive  Officer
of Newco in  consideration  for salary and bonus,  effective as of the Effective
Time of the Merger. The term of the Employment Agreement is three (3) years. The
Employment  Agreement is  terminable  by Mr. Norrod upon thirty (30) days notice


                                      -20-

the  payment  of  severance  benefits.  See  "The  Asset   Transactions--Related
Agreements--Employment Agreement of James D. Norrod."

         Interests of Certain Persons in the Asset Transactions.  In considering
the recommendation of the Telebit Board with respect to the Asset  Transactions,
shareholders  of Telebit should be aware that certain  officers and directors of
Telebit  have  interests  in the  Asset  Transactions,  that  present  them with
potential  conflicts of  interests.  See "The Asset  Transactions--Interests  of
Certain Persons in the Asset Transactions."

         Certain  Federal  Income Tax  Considerations.  As a result of the Asset
Sale,  the Company  should  recognize  taxable  gain equal to the amount paid by
Newco (including liabilities of the Company assumed) less the Company's adjusted
tax basis in the  assets  disposed  of in the  Asset  Sale.  The  amount of gain
subject to federal  income tax may be  reduced by the  Company's  net  operating
losses. See "The Asset Transactions--Certain Federal Income Tax Considerations."

         Accounting  Treatment.  The Asset Sale is expected to be accounted  for
under the purchase method of accounting,  with Newco as the acquiring  party, in
accordance with generally  accepted  accounting  principles.  Under the purchase
method of accounting, the purchase price paid for certain assets and liabilities
of Telebit will be allocated to the respective  assets  acquired and liabilities
assumed based upon their estimated fair values,  with any excess of the purchase
price over the estimated  fair value of net assets  acquired  being  recorded as
goodwill. See "The Asset Transactions--Accounting Treatment."

OPINIONS OF FINANCIAL ADVISOR

         Allen & Company  Incorporated  ("Allen")  has  delivered a letter dated
July 20, 1996 to the Telebit  Board  setting  forth its  opinions as of July 20,
1996 (which  opinions  were  confirmed  as of ________  __, 1996) to the Telebit
Board to the effect that, as of the date of such opinions,  the consideration to
be received  (a) by holders of Telebit  Common  Stock  pursuant to the Merger is
fair to such holders from a financial point of view and (b) by Telebit  pursuant
to the Asset Sale is fair to Telebit  from a financial  point of view.  The full
text of the  opinions of Allen,  dated  __________  ___,  1996,  describing  the
assumptions made, the matters considered and limits of the review undertaken, is
attached  to this  Proxy  Statement  as  Appendix  D.  Such  opinions  should be

APPRAISAL RIGHTS

                  Holders  of Telebit  Common  Stock who vote  against:  (i) the
proposal  to approve  and adopt the Merger  Agreement  and  consummation  of the
Merger;  or (ii) the proposal to approve and adopt the Asset Purchase  Agreement
and approve  consummation  of the Asset Sale; or (iii) both proposals may, under
certain  circumstances and by following procedures  prescribed by the California
General Corporation Law, exercise  dissenters' rights and receive cash for their
shares of Telebit Common Stock. The failure of a dissenting Telebit  shareholder
to follow the appropriate procedures, including voting against: (i) the proposal
to approve  and adopt the  Merger  Agreement  and  approve  consummation  of the
Merger;  or (ii) the proposal to approve and adopt the Asset Purchase  Agreement
and approve  consummation  of the Asset Sale;  or (iii) or both  proposals,  may
result in the  termination  or waiver of


                                      -21-


such  rights.  A copy of the  California  General  Corporation  Law  relating to
Appraisal  Rights is attached to this Proxy Statement as Appendix E. See "Rights
of Dissenting Shareholders."


REGULATORY APPROVALS

         Telebit  is not  aware  of any  federal,  state or  foreign  regulatory
approvals that must be obtained in order to consummate the Transactions,  except
that the Merger is reportable  by Telebit and Cisco under the  Hart-Scott-Rodino
Antitrust  Improvements  Act of 1976,  as  amended  ("HSR  Act"),  and the rules
promulgated  thereunder  by the United  States  Federal  Trade  Commission  (the
"FTC").  The Merger may not be consummated until  notifications  have been given
and certain  information  furnished to the FTC and the Antitrust Division of the
United States  Justice  Department  (the  "Antitrust  Division"),  and specified
waiting period  requirements  have been  satisfied or waived.  Telebit and Cisco
filed their respective  Notification and Report Forms required under the HSR Act
with the FTC and the  Antitrust  Division  on August 5, 1996 and the  applicable
waiting period under the HSR Act expired/was waived on ______________ ___, 1996.
See "Regulatory Matters."

CERTAIN LEGAL PROCEEDINGS

         On August 2,  1996,  a  complaint  was filed in the  Middlesex  County,
Massachusetts,  Superior  Court,  entitled  Dr.  Herb  Golden v.  James P. (sic)
Norrod,  Michael K. Ballard,  C. Richard  Kramblich (sic),  Scott J. Loftesness,
Cisco Systems,  Inc. and Telebit  Corporation  (Civil Action No.  96-4537).  The
lawsuit relates to the proposed transactions.

         The suit alleges,  among other  things,  that the Merger and Asset Sale
will  not be in the best  interest  of  Telebit's  shareholders.  The suit  also
alleges that the consideration  being paid in connection with the Asset Sale and
the proposed  Merger  Consideration  of $13.35 per share are below market value.
The  suit  asks  the  court to  enjoin  the  closing  of the  transactions,  or,
alternatively, to award unspecified damages from the defendants in the event the
transactions are consummated.

         Cisco and Telebit  believe that the suit is without merit and intend to
defend it vigorously.

         At the Special Meeting, shareholders of record of the Company as of the
close of business on the Record  Date,  will be asked:  (i) to consider and vote
upon a  proposal  to  approve  and adopt the  Merger  Agreement  and to  approve
consummation  of the Merger  and (ii) to  consider  and vote upon a proposal  to
approve and adopt the Asset Purchase  Agreement and to approve  consummation  of
the Asset  Sale;  (iii) to  consider  and vote upon a proposal  to  adjourn  the
Special  Meeting in the event there are not sufficient  votes at the time of the
Special Meeting to approve and adopt the Merger Agreement and approve the Merger
and/or  approve and adopt the Asset  Purchase  Agreement and the Asset Sale; and
(iv) to transact  such other  business as may  properly  come before the Special
Meeting or any postponements or adjournments thereof.

RECORD DATE AND OUTSTANDING SHARES

         The Telebit  Board has fixed  September 11, 1996 as the Record Date for
the  determination  of the shareholders of the Company entitled to notice of and
to vote at the Special  Meeting.  Only holders of record of Telebit Common Stock
on the  Record  Date will be  entitled  to notice of and to vote at the  Special
Meeting.  As of the Record  Date,  there were  ______________  shares of Telebit
Common Stock  outstanding and entitled to vote, which were held by approximately
___ holders of record.  Each record holder of Telebit Common Stock on the Record
Date is  entitled  to cast one vote  per  share,  exercisable  in  person  or by
properly  executed proxy, on each matter properly  submitted for the vote of the
shareholders of the Company at the Special Meeting.

QUORUM; ABSTENTIONS AND BROKER NON-VOTES

         Abstentions  and broker  non-votes each will be included in determining
the  number of shares  present  and  voting at the  meeting  for the  purpose of
determining the presence of a quorum. A "non-vote" occurs when a nominee holding
shares  for a  beneficial  owner  votes  on one  proposal,  but does not vote on
another proposal  because,  in respect of such other proposal,  the nominee does
not have discretionary  voting power and has not received  instructions from the
beneficial owner. Because approval of: (i) the Merger Agreement and consummation
of the Merger and (ii) the Asset  Purchase  Agreement  and  consummation  of the
Asset Sale each require the  affirmative  vote of a majority of the  outstanding
shares of Telebit Common Stock entitled to vote thereon,  abstentions and broker
non-votes on either or both proposals will have the same effect as votes against
the Merger  Agreement  and  consummation  of the Merger  and/or  Asset  Purchase
Agreement and consummation of the Asset Sale, as the case may be.

         THE ACTIONS  PROPOSED IN THIS PROXY  STATEMENT ARE NOT MATTERS THAT CAN
BE VOTED ON BY BROKERS HOLDING SHARES FOR BENEFICIAL  OWNERS WITHOUT THE OWNERS'
SPECIFIC  INSTRUCTIONS.  ACCORDINGLY,  ALL  BENEFICIAL  OWNERS OF TELEBIT COMMON
STOCK ARE URGED TO RETURN THE  ENCLOSED  PROXY  CARD  MARKED TO  INDICATE  THEIR
VOTES.


                                      -23-


         An  automated  system  administered  by the  Company's  transfer  agent
tabulates the votes.  The vote on each  proposal  submitted to  shareholders  is
tabulated separately.

         First  Interstate  Bank of  California  will serve as the  Inspector of
Elections and will count all votes and ballots.

VOTE REQUIRED AND CERTAIN VOTING INFORMATION

         The  representation in person or by proxy of at least a majority of the
outstanding  shares of Telebit  Common Stock  entitled to vote at the meeting is
necessary  to  constitute  a  quorum  for  the  transaction  of  business.   The
affirmative vote of the majority of shares present,  in person or represented by
proxy,  and voting on that  matter is  required:  (i) to  approve  and adopt the
Merger  Agreement and to approve  consummation of the Merger and (ii) to approve
and adopt the Asset Purchase Agreement and to approve  consummation of the Asset
Sale.

         As of the Record Date,  directors and executive officers of the Company
and their affiliates may be deemed to be the beneficial  owners of approximately
16.4% of the  outstanding  shares of Telebit  Common  Stock.  The members of the
Telebit Board and certain officers have each entered into Voting Agreements with
Cisco,  pursuant to which each such holder has agreed to vote their shares:  (i)
in favor of approval of the Merger  Agreement,  the Merger,  the Asset  Purchase
Agreement,  the Asset Sale and any matter that could  reasonably  be expected to
facilitate  the Merger and the Asset Sale and (ii)  against any proposal for any
recapitalization,  merger,  sale of assets or other business  combination (other
than the Merger and the Asset Sale) between the Company and any person or entity
other than Cisco or any other action or agreement  that would result in a breach
of any covenant, representation or warranty or any other obligation or agreement
of the Company  under the Merger  Agreement or the Asset  Purchase  Agreement or
which could result in any of the conditions to the Company's  obligations  under
the Merger  Agreement or the Asset Purchase  Agreement not being  fulfilled.  In
addition,  each such holder has, pursuant to the Voting  Agreements,  granted an
irrevocable  proxy to Cisco to vote such shares as  aforesaid.  The  outstanding
shares of Telebit Common Stock subject to the Voting  Agreements  represent 7.2%
of the votes entitled to be cast by holders of shares of Telebit Common Stock as
of the Record Date, and 16.4%  assuming  exercise of all options held by parties
of the Voting  Agreements.  The Telebit recommends a vote by the shareholders of
the Company FOR  approval an adoption of the Merger  Agreement  and  approval of
consummation  of the Merger and FOR approval and adoption of the Asset  Purchase
Agreement   and  approval  of   consummation   of  the  Asset  Sale.   See  "The
Merger--Related Agreement--Voting Agreements.

consummation  of the Merger and FOR approval and adoption of the Asset  Purchase
Agreement   and  approval  of   consummation   of  the  Asset  Sale.   See  "The

                                THE TRANSACTIONS

BACKGROUND OF THE TRANSACTIONS

         On May 22, 1996, John Celii,  Director of Business Development of Cisco
contacted James D. Norrod,  President and Chief Executive Officer of Telebit, to
arrange a meeting to consider the merits of a  combination  of the two companies
or otherwise  entering into a business  relationship  to provide  Telebit's MICA
technology to Cisco.

         On May 24,  1996,  Michael K.  Ballard,  Executive  Vice  President  of
Marketing  of  Telebit,  and Brian D.  Cohen,  Vice  President  of  Finance  and
Administration  and Chief  Financial  Officer of Telebit,  met at the offices of
Telebit in  Chelmsford,  Massachusetts  with Mr. Celii and Kevin  Kennedy,  Vice
President of the Branch Office Division of the Business Access Unit of Cisco, to
discuss  Telebit's  digital  modem  product  plans and  strategy  and to explore
various alternatives for a relationship between Telebit and Cisco.

         On May 25,  1996,  Mr.  Norrod  met in San  Jose,  California  with Mr.
Kennedy,  to discuss the business strategies of Telebit and Cisco and to explore
various alternatives for a relationship between the two companies.

         On May  29,  1996,  Telebit  and  Cisco  entered  into  a  Confidential
Non-Disclosure Agreement.

         On May 31, 1996, representatives of Cisco and Telebit senior management
met at the offices of Cisco in San Jose,  California to exchange information and
discuss the strategic and  transaction  objectives of Telebit and Cisco, as well
as product strategies, organizational, legal and financial issues. Various forms
of  transaction  structures,  designed  to  focus  on  the  objectives  of  both
companies, were also explored.

         On  June  6,  1996,   Telebit  and  Cisco   amended  the   Confidential
Non-Disclosure  Agreement dated May 29, 1996 (as amended,  the  "Confidentiality
Agreement") to add certain non-solicitation provisions applicable to Telebit.

         On  June  6-7,  1996,  representatives  of  Cisco  and  Telebit  senior
management  and each  party's  independent  accountants  met at the  offices  of
Telebit in Chelmsford, Massachusetts to discuss financial, product and technical
matters and to conduct a due diligence review of Telebit.

         On June 13,  1996,  Messrs.  Cohen and Norrod  met with John  Chambers,
President and Chief  Executive  Officer of Cisco,  as well as senior  members of
Cisco management, to discuss the two companies' business strategies and explored
financial  and  structural  alternatives  for a  transaction  involving  the two
companies.  Mr.  Chambers  proposed a transaction  whereby an independent  third
company ("ICo.") would purchase in an all cash tender offer, at $14.33 per share
on a fully diluted basis, all of the outstanding shares of Telebit Common Stock.
Under this  proposal  Cisco would enter into an exclusive  license with ICo. for
the MICA  technology  and ICo.  would  assume  responsibility  for the  on-going
operations  of  Telebit's  modem  and  networking  product  lines  (the  "Legacy
Business").  The  acquisition  would be  financed  through  a bank  loan to ICo.
guaranteed by Cisco.

         On June  18-19,  1996,  senior  management  representatives  of the two
companies, together with each party's legal counsel and independent accountants,
met at the office of Testa, Hurwitz & Thibeault, LLP in Boston, Massachusetts to
discuss financial, legal and structural alternatives for the transaction.


                                      -27-


During these  meetings the ICo.  structure  was  discussed  and rejected by both
parties and other structural alternatives pursued.

         On June 21, 1996, Cisco, by letter from Don Listwin, Vice President and
General  Manager  Access  Business  Unit, to James D. Norrod,  offered to pursue
discussions  along one of two lines:  (i) an all cash tender offer at $12.00 per
share on a fully  diluted basis or (ii) a  cash-for-stock  merger of Telebit and
Cisco at $14.50 per share on a fully diluted basis and  simultaneous  asset sale
of Telebit's Legacy Business valued at $35 million.

         By letters dated June 22, 1996,  and June 24, 1996,  from Mr. Norrod to
Mr. Listwin,  Telebit agreed to pursue discussions of a combined  cash-for-stock
merger/asset sale.

         During the week of June 24,  1996,  Mr.  Cohen  engaged the  investment
banking firm of Allen & Company  Incorporated  to assist  Telebit in  evaluating
various alternatives and the appropriate range of valuation, including the asset
sale  component.  In  addition,  discussions  among  Telebit  management  ensued
regarding  the asset sale  component of the proposed  Transactions.  During such
discussions it was determined that Mark R. Wilson, Vice President, Operations of
Telebit, would undertake the asset sale component of the proposed Transactions.

         On  June  27,  1996,   representatives  of  Telebit  and  Cisco  senior
management,  Mr. Wilson,  each party's legal counsel,  and financial advisors to
Cisco  and  Telebit  met at the  office of Testa,  Hurwitz &  Thibeault,  LLP to
discuss the  preliminary  terms and  structure for a business  combination.  The
decision was made that Mr. Wilson would consult with an investment  banking firm
to consider the valuation of Telebit's Legacy Business.

         On June 28-29,  1996,  Mr.  Wilson met with his  financial  advisor and
prepared and  distributed  a proposal for the asset sale valued $22 million to a
member of Cisco's senior management.

         On June 29-30, 1996, conference calls were held between representatives
of Telebit and Cisco senior  management  and Mr. Wilson to discuss Mr.  Wilson's
proposal. Mr. Wilson's proposal was rejected by Cisco.

         On July 1, 1996, Messrs. Celii and Cohen discussed a range of financial
terms for the proposed Transactions.

         On July 3, 1996, Mr. Norrod, in a discussion with Mr. Celii,  expressed
an interest in acquiring Telebit's Legacy Business.

         On July 7, 1996,  the  Telebit  Board met to  evaluate  the merits of a
cash-for-stock merger with Cisco and a sale to a corporation ("Newco") formed by
Mr.  Norrod,  of Telebit's  Legacy  Business.  The Telebit  Board  discussed the
proposed  financial and  structural  terms of the offer.  The Telebit Board also
formed a special committee (the "Special  Committee"),  consisting of C. Richard
Kramlich and Scott J.  Loftesness,  to consider and evaluate the proposal and to
recommend a course of action to the full Board. The decision was made to proceed
with  negotiations.  Following  the  meeting of the Telebit  Board,  the Special
Committee met to discuss the proposed Transactions and authorized Brian D. Cohen
to act on  behalf of  Telebit  in all  negotiations  with  Cisco and with  Newco
regarding the proposed Transactions.

         During the period from July 8, 1996  through  July 17,  1996,  numerous
telephone  conferences were held to negotiate the various agreements relating to
the asset sale.


                                      -28-


         On July 17, 1996,  a telephone  conference  was held to  negotiate  the
agreements related to the cash-for-stock merger, including the Merger Agreement,
Voting Agreements and Stock Option Agreement.

         On July  19,  1996,  Mr.  Chambers  and  Mr.  Norrod  met by  telephone
conference call to discuss the status of the proposed Transactions.  During that
meeting Mr. Chambers informed Mr. Norrod that, in light of recent decline in the
market prices of networking  company stocks generally,  Cisco would be unable to
meet the $14.50 per share offer contained in its letter dated June 21, 1996. Mr.
Chambers stated that Cisco would be prepared to offer $13.07 per share.

         On July 19, 1996, the Special Committee met to review the status of the
negotiations  and to discuss the pricing  change,  the  feasibility of obtaining
shareholder  approval  of the  Transactions  at a lower  price  in  light of the
current market price for Telebit Common Stock and the potential  market reaction
to the  Transactions.  Telebit's  legal  counsel then  reviewed the terms of the
proposed Merger Agreement,  including the ancillary  documents thereto,  and the
Asset  Purchase  Agreement,  including  the  ancillary  documents  thereto,  and
reviewed  the Telebit  Board's  fiduciary  duties in  considering  the  proposed
Transactions.  Allen & Company  then made a  presentation  to the Telebit  Board
regarding the revised price and reviewed its financial  analysis of the proposed
Transactions  in light of the  proposed  price.  The  Telebit  Board  authorized
management   to  continue   discussions   with  Cisco   regarding  the  proposed
Transactions, specifically with regard to price.

         On July 20, 1996, a number of telephone  conferences  between Mr. Cohen
and various members of Cisco senior management were held during which agreement,
subject to  approval by the  respective  Boards of  Directors,  was reached at a
price of $13.35 per share.

         On July 20, 1996, at a meeting of the Special  Committee of the Telebit
Board:  (i) Mr. Cohen  discussed  the financial  and  structural  aspects of the
proposed Merger and Asset  Transactions;  (ii) Telebit's legal counsel  reviewed
principal terms of the proposed Asset Purchase Agreement, including the terms of
ancillary  documents thereto,  and the Merger Agreement,  including the terms of
the ancillary documents thereto; and (iii) Telebit's financial advisor,  Allen &
Company,  delivered its opinions that, as of such date, (a) the consideration to
be  received by the  holders of Telebit  Common  Stock in the Merger was fair to
such  holders  from a financial  point of view and (b) the  consideration  to be
received  by  Telebit  pursuant  to the Asset  Sale was fair to  Telebit  from a
financial point of view.

         On July 20, 1996, following the meeting of the Special Committee,  at a
meeting  of the  Telebit  Board,  (i) Mr.  Cohen  discussed  the  financial  and
structural  aspects of the Merger and Asset  Transactions;  (ii) Telebit's legal
counsel reviewed the terms of the proposed Asset Purchase  Agreement,  including
the  terms  of the  ancillary  agreements  thereto,  and the  Merger  Agreement,
including  the  terms  of the  ancillary  agreements  thereto;  (iii)  Telebit's
financial  advisor,  Allen & Company,  delivered  its opinions  that, as of such
date, (a) the consideration to be received by holders of Telebit Common Stock in
the Merger was fair to such holders  from a financial  point of view and (b) the
consideration  to be received by Telebit  pursuant to the Asset Sale was fair to
Telebit from a financial point of view; (iv) the Special  Committee  recommended
that the Telebit Board (a) conclude that the Merger and Asset Sale are advisable
and in the best  interests of the Company and the  Company's  shareholders,  (b)
approve and adopt the Merger Agreement and the Asset Purchase  Agreement and (c)
recommend that the Company's  shareholders  (1) approve the Merger Agreement and
approve  consummation  of the Merger and (2) adopt the Asset Purchase  Agreement
and approve  consummation of the Asset Sale. The Telebit Board,  with Mr. Norrod
abstaining  on votes  related to the Asset Sale and Mr.  Ballard  abstaining  on
votes related to the Merger,


                                      -29-


then:  (i)  approved  and adopted the Merger  Agreement  and the Asset  Purchase
Agreement  and (ii)  voted to  recommend  that the  Company's  shareholders  (a)
approve and adopt the Merger  Agreement and approve  consummation  of the Merger
and (b) approve and adopt the Asset Purchase Agreement and approve  consummation
of the Asset Sale.

         On July 20-21,  1996,  a number of  telephone  conferences  between Mr.
Cohen and Charles  Giancarlo,  Vice President of Business  Development of Cisco,
were held during which final  agreement was reached on the  structural  terms of
the proposed Transactions.

         On July 21, 1996,  following final approval of their respective  Boards
of Directors,  the duly authorized  representatives  of the parties executed the
Merger  Agreement,  the Stock Option Agreement and the Asset Purchase  Agreement
and certain shareholders of Telebit executed Voting Agreements.

         On July  22,  1996,  Telebit  and  Cisco  issued a joint  news  release
announcing the Merger.

REASONS FOR THE TRANSACTIONS; RECOMMENDATION OF THE BOARD OF DIRECTORS

         The Telebit  Board,  at meetings  held on July 7, July 19, and July 20,
1996 and on  several  informal  conferences  held  prior to such time and before
final approval of the Transactions,  in evaluating the proposed Transactions and
in  determining to recommend  that the Company's  shareholders:  (i) approve and
adopt the  Merger  Agreement  and  approve  consummation  of the Merger and (ii)
approve and adopt the Asset Purchase  Agreement and approve  consummation of the
Asset Sale,  carefully  reviewed  the terms of the Merger  Agreement,  the Asset
Purchase  Agreement,  the Merger and the Asset  Transactions  with the Company's
management and with representatives of each of Testa, Hurwitz & Thibeault,  LLP,
counsel  to the  Company,  and  Allen  &  Company  Incorporated,  the  Company's
financial advisor. In reaching its conclusion,  the Telebit Board considered the
following principal factors:

      (i)         The Telebit Board's belief that,  despite the market potential
                  of the  Company's  MICA  technology,  increasing  competition,
                  industry  consolidation and rapid  technological  change would
                  make it difficult  for Telebit to compete  effectively  due to
                  its  relatively   small  size  in  an  industry   increasingly
                  characterized  by large companies with  substantially  greater
                  resources;

     (ii)         Current industry,  economic and market  conditions  related to
                  the  Company,  as  well  as  Telebit's  business,   prospects,
                  financial performance and condition,  operations,  technology,
                  management and competitive position:  noting specifically that
                  the  Company has  experienced  declining  revenue  since 1993,
                  recorded net losses in excess of $26 million  since 1993,  and
                  had losses in five (5) of the last six (6) fiscal quarters and
                  that   working   capital,   especially   cash,   has  declined
                  significantly  since the Company's  initial public offering in
                  April 1990;

    (iii)         Current  financial  market  conditions for networking  company
                  stocks generally and historical  market price,  volatility and
                  related  trading  information  with respect to Telebit  Common
                  Stock;

     (iv)         The belief of the Company's  management  and the Telebit Board
                  that certain trends in the  networking  industry are adversely
                  affecting  the  Company's   margins  and  ability  to  compete
                  effectively,  including  the need of  market  participants  to
                  achieve, rapidly,  critical mass to obtain profitability,  the
                  trend  towards   commodity   pricing  of  products,   and  the
                  increasing  domination of the market and distribution channels
                  by large companies such as Cisco;


                                      -30-



      (v)         The all-cash  consideration to be received by the shareholders
                  in the Merger and the fact that the consideration  represented
                  a  significant  premium  over the price  range of the  Telebit
                  Common Stock (the Merger  Consideration  represented a premium
                  of  approximately  50%  over the  90-day  rolling  average  of
                  Telebit  Common  Stock  preceding  the   announcement  of  the
                  Transactions);

     (vi)         The terms and conditions of the Merger Agreement and the Stock
                  Option Agreement including the break-up fees, non-solicitation
                  provisions,  conditions to closing and termination provisions.
                  In  particular,   the  Telebit  Board   concluded  that  these
                  provisions  provided  reasonable  flexibility  for  Telebit to
                  exercise its fiduciary  duties in the event of an  unsolicited
                  competing bid prior to consummation of the Merger; and

    (vii)         The opinions of Allen rendered at the July 20, 1996 meeting of
                  the Telebit Board (and subsequently confirmed in writing) that
                  the  consideration to be received by (a) Telebit  stockholders
                  pursuant  to  the  Merger  is  fair  to  such  holders  from a
                  financial point of view and (b) Telebit  pursuant to the Asset
                  Sale is fair to Telebit from a financial point of view.

         The Telebit  Board also  considered  a number of  potentially  negative
factors in its  deliberations  concerning the Transactions,  including,  but not
limited  to:  (i) the risk  that  the  Company's  ability  to  license  the MICA
technology would be limited following announcement of the proposed Transactions;
(ii) the  requirement of stockholder  approval of the  Transactions  and process
involved  in  obtaining  such  approval,  in  particular,   the  possibility  of
substantial  delays in consummating the Transactions due to regulatory and other
requirements and the concern that such a delay could have a significant  adverse
effect on  Telebit's  sales  and  marketing  efforts,  employee  base,  customer
relationships,  and future financial results if not managed properly;  and (iii)
the fact that upon consummation of the Transactions, current shareholders of the
Company will cease to have any  continuing  interest in the Company,  other than
the right to payment of the Merger Consideration in accordance with the terms of
the Merger Agreement,  and, accordingly,  after consummation of the Merger, will
have no opportunity to participate in any  appreciation  in the value of Telebit
Common  Stock,  other than the  foregoing.  The  Telebit  Board  discussed  with
management the prospects for  combinations  with  companies  other than Cisco as
well as the risks and benefits of executing its business plan as an  independent
company.

         In view of the variety of factors  considered by the Telebit Board, the
Telebit  Board did not find it  practicable  to  quantify  or  otherwise  assign
relative weight to the specific factors considered.

         Considering all of the above factors,  the Telebit Board concluded that
it is likely that in an increasingly  competitive  environment the Company would
not  have a  value  higher  than  that  which  existed  at  the  time  that  the
Transactions were approved. The Telebit Board also considered that the potential
for a reduction  in the value or  profitability  of the Company  over time might
negatively  impact the market price of the Telebit Common Stock and the value of
the Company. In addition,  management, based on discussions with other companies
during the past year regarding the possible sale of Telebit and its knowledge of
Cisco's business strategy and the relative importance of the MICA Assets in such
strategy,  concluded  that it was unlikely  that in the near term any  purchaser
would be willing to pay a higher  price than that to be  received  in the Merger
and communicated this to the Special Committee and the Telebit Board.

         In light of the foregoing,  the Telebit  Board,  based on the unanimous
recommendation of the Special  Committee,  has approved the Merger Agreement and
consummation of the Merger by the unanimous vote of all non-interested directors
and  believes  that the Merger is fair and in the best  interests of Telebit and
its  shareholders.  Mr.  Ballard,  who  will  be  employed  by  Cisco  following


                                      -31-


consummation  of the  Transactions,  abstained  from  voting on the  proposal to
approve the Merger Agreement and  consummation of the Merger.  The Telebit Board
based  on the  unanimous  recommendation  of the  Special  Committee,  also  has
approved the Asset Purchase  Agreement and consummation of the Asset Sale by the
unanimous  vote of all  non-interested  directors  and  believes  that the Asset
Purchase  Agreement and  consummation  of the Asset Sale is fair and in the best
interest of Telebit and its  shareholders.  Mr. Norrod,  the President and Chief
Executive  Officer of Telebit and President,  sole director and sole stockholder
of Newco,  abstained  from voting on the proposal to approve the Asset  Purchase
Agreement and  consummation  of the Asset Sale.  The Telebit Board  recommends a
vote by the  shareholders of the Company FOR approval and adoption of the Merger
Agreement  and  approval  of  consummation  of the Merger and FOR  approval  and
adoption of the Asset  Purchase  Agreement and approval of  consummation  of the
Asset Sale.

                                   THE MERGER

GENERAL

         The  Merger  Agreement  provides  for the  merger  of a  newly  formed,
wholly-owned  subsidiary of Cisco with and into Telebit,  with Telebit to be the
surviving corporation of the Merger and thus become a wholly-owned subsidiary of
Cisco.  The discussion in this Proxy Statement of the Merger and the description
of the principal terms and conditions of the Merger Agreement are subject to and
qualified  in their  entirety by reference  to the Merger  Agreement,  a copy of
which is attached  to this Proxy  Statement  as  Appendix A and is  incorporated
herein by reference.  Shareholders are urged to read the Merger Agreement in its
entirety.

CONVERSION OF SHARES AND VESTED OPTIONS

         Upon consummation of the Merger, each then outstanding share of Telebit
Common Stock (other than shareholders who properly exercise  dissenters'  rights
under  California  Law,  if  any)  will  be  canceled  and  extinguished  and be
automatically  converted  into the right to  receive  $13.35  per share in cash,
without interest.  Upon consummation of the Merger,  the certificates  currently
representing  Telebit Common Stock will no longer represent Telebit Common Stock
and will  represent  only the right to receive  the Merger  Consideration.  Upon
consummation of the Merger,  current Telebit shareholders will cease to have any
continuing  interest in  Telebit,  other than the right to payment of the Merger
Consideration in accordance with the terms of the Merger Agreement.

         Upon  consummation of the Merger,  each then  outstanding  option under
Telebit's 1985 Employee Stock Incentive  Program (the "1985 Plan"),  the assumed
Octocom  Systems,  Inc.  Stock  Option  Plan  (the  "Octocom  Plan"),  the  1994
Non-Employee  Director Stock Option Plan (the "Non-Employee  Director Plan") and
the 1995 Stock  Option  Plan (the "1995  Plan" and,  collectively  with the 1985
Plan,  the Octocom Plan and the  Non-Employee  Director Plan, the "Telebit Stock
Option Plans") shall,  to the extent  exercisable at such time for vested shares
of Telebit Common Stock (including any shares which vest on an accelerated basis
in connection with the Merger) be canceled, and the holder of each such canceled
option  shall be  entitled  to  receive a cash sum per  vested  share of Telebit
Common Stock  subject to the canceled  option equal to the Merger  Consideration
less the exercise  price per share of Telebit  Common Stock in effect under that
option  immediately  prior to consummation of the Merger. As of the Record Date,
options to purchase an aggregate of 1,283,307  vested  shares of Telebit  Common
Stock under the Telebit Stock Option Plans were  outstanding.  In addition,  the
vesting of options to purchase an aggregate of 183,183  shares of Telebit Common
Stock  will be  accelerated  in  connection  with  consummation  of the  Merger,
including  options to  purchase  114,558  shares of Telebit  Common  Stock under
certain of Telebit's  employment contracts and options to purchase 37,665 shares
of Telebit Common Stock under the 1985 Plan.

TREATMENT OF UNVESTED EMPLOYEE STOCK OPTIONS

         Each option outstanding upon consummation of the Merger under Telebit's
1995  Plan  which is held by a Telebit  employee  who will  continue  his or her
employment  with Telebit  following  consummation  of the Merger  shall,  to the
extent  that the option is not at such time  exercisable  for  vested  shares of
Telebit Common Stock, be assumed by Cisco and shall  automatically  be converted
into an  option  to  purchase  the  number  of  shares  of Cisco  Common  Stock,
determined by multiplying  the number of unvested shares of Telebit Common Stock
subject to that  option  immediately  prior to  consummation  of the Merger by a
factor  obtained  by  dividing  the Merger  Consideration  by the average of the
closing  selling  price per share of Cisco  Common Stock as quoted on Nasdaq for
each of the five  trading  days ending with the second  trading day  


                                      -33-


immediately  preceding  the date of the  Special  Meeting,  rounded  down to the
nearest whole number of shares of Cisco Common Stock,  at an exercise  price per
share,  rounded up to the nearest  whole cent,  equal to the exercise  price per
share of the Telebit option at the time of consummation of the Merger multiplied
by a factor  obtained by dividing the average of the closing  selling  price per
share of Cisco  Common  Stock as quoted  on Nasdaq  for each of each of the five
trading days ending with the second day  immediately  preceding  the date of the
Special  Meeting by the Merger  Consideration.  The other  terms of the  options
under Telebit's 1995 Plan assumed by Cisco,  including vesting  schedules,  will
remain unchanged.  Cisco will file a Registration Statement of Form S-8 with the
Commission  with respect to the share of Cisco Common  Stock  issuable  upon the
exercise of the  assumed  Telebit  options.  As of the Record  Date,  options to
purchase an aggregate of 107,077 shares of Telebit Common Stock were outstanding
under  Telebit's  1995  Plan and are  expected  to be  assumed  by Cisco  which,
following consummation of the Merger and assuming a price of $_____ per share of
Cisco Common Stock, will be exercisable for approximately  _____________  shares
of Cisco Common Stock.

         Following  the  Effective  Time,  with  respect to any  Telebit  option
assumed by Cisco, Cisco will issue to each person who, immediately prior thereto
was a holder  of an  outstanding  Telebit  option,  a  document  evidencing  the
assumption  of such option by Cisco.  Such  assumption  will be automatic and no
action  will be  required  on the part of the  option  holder  to  convert  such
holder's Telebit option into an option to purchase shares of Cisco Common Stock.

         Each option outstanding upon consummation of the Merger under Telebit's
1995 Plan which is held by an employee of Telebit who will become an employee of
Newco immediately following consummation of the Merger shall, to the extent that
the option is not at such time  exercisable  for vested shares of Telebit Common
Stock,  be treated in the manner  determined  by Newco,  and Cisco  shall,  upon
written  receipt of notice from Newco as to such manner of  treatment,  take all
reasonable  ministerial  action  necessary to effect any required  allocation of
outstanding  options under the 1995 Plan between those options  assumed by Cisco
and any options assumed by Newco.  All other options  outstanding at the time of
consummation  of the Merger under the Telebit  Stock Option Plans shall,  to the
extent not  exercisable  for vested shares of Telebit Common Stock at that time,
terminate and cease to be outstanding at the time of  consummation of the Merger
and shall not be assumed by either Cisco or Newco. As of the Record  Date, there
shall be no such options to be so terminated.

         Outstanding  purchase  rights  under the Telebit  1990  Employee  Stock
Purchase Plan (the "Telebit  ESPP") shall be exercised  upon the earlier of: (i)
the next  scheduled  purchase  date under the Telebit  ESPP or (ii)  immediately
prior to  consummation of the Merger,  and each  participant in the Telebit ESPP
shall  accordingly  be issued shares of Telebit  Common Stock at that time which
shall  automatically be converted upon consummation of the Merger into the right
to receive the Merger Consideration.  The Telebit ESPP shall terminate with such
exercise date, and no purchase rights shall be subsequently granted or exercised
under  the  Telebit  ESPP.  A  Telebit  employee  who will  continue  his or her
employment with Telebit  following  consummation of the Merger and who meets the
eligibility  requirements for participation in the Cisco Employee Stock Purchase
Plan shall be eligible  to begin  payroll  deductions  under that plan as of the
start date of the first  offering  period  thereunder  beginning at least thirty
(30) days after consummation of the Merger.

EXCHANGE OF CERTIFICATES

         As of the Effective  Time,  Cisco shall deposit with The First National
Bank of Boston (the  "Exchange  Agent"),  for the  benefit of Telebit  share and
option holders (other than shareholders who properly exercise dissenters' rights
under California Law, if any), the aggregate Merger Consideration (the


                                      -34-


"Exchange  Fund") to be paid to share and option  holders in exchange  for their
outstanding  shares of Telebit  Common Stock or vested Telebit  options,  as the
case may be.

         As  soon  as  practicable   after  the  Effective  Time,  a  letter  of
transmittal with instructions for use in effecting the surrender of certificates
and stock option  agreements  with respect to vested  Telebit  options  ("Vested
Option  Agreements") in exchange for the Merger  Consideration will be mailed to
each  Telebit  share and option  holder  (other than  shareholders  who properly
exercise  dissenters' rights under California Law, if any) for use in exchanging
Telebit Common Stock  certificates  and Vested Option  Agreements for cash. Upon
surrender of a Telebit Common Stock certificate or a Vested Option Agreement for
cancellation to the Exchange Agent in connection with the Merger,  together with
such letter of  transmittal,  duly completed and validly  executed in accordance
with the instructions  thereto,  the holder of such certificate or Vested Option
Agreement  will  be  entitled  to  receive  in  exchange   therefor  the  Merger
Consideration.  If  payment  for  the  surrender  of any  Telebit  Common  Stock
certificate  or Vested Option  Agreement is to be made to a name other than that
in which  the  Telebit  Common  Stock  certificate  or Vested  Option  Agreement
surrendered in exchange  therefor is  registered,  it will be a condition of the
payment  thereof that the Telebit  Common  Stock  certificate  or Vested  Option
Agreement so surrendered  be properly  endorsed and otherwise in proper form for
transfer and that the person  requesting  such payment have paid to Cisco or any
agent  designated  by it any  transfer or other taxes  required by reason of the
payment of such cash to any name other than that of the registered holder of the
Telebit Common Stock  certificate  or Vested Option  Agreement  surrendered,  or
established to the satisfaction of Cisco or any agent designated by it that such
tax has been paid or is not payable.  Immediately after the Effective Time, each
outstanding  Telebit Common Stock certificate or Vested Option Agreement will be
deemed for all  corporate  purposes  (other than the payment of  dividends  with
respect to a Telebit  Common Stock  certificate)  to represent only the right to
receive,  upon surrender as  contemplated  by the Merger  Agreement,  the Merger
Consideration.

         Any portion of the Exchange  Fund which  remains  undistributed  to the
holders of Telebit  Common  Stock or vested  Telebit  options one year after the
Effective  Time will be  delivered  to Cisco,  upon  demand,  and any holders of
Telebit Common Stock or vested  Telebit  options  (other than  shareholders  who
properly exercise  dissenter's rights under California Law, if any) who have not
theretofore  complied with the exchange  procedure must  thereafter look only to
Cisco for the Merger Consideration.

         Neither  Telebit  nor Cisco  will be liable  to any  holder of  Telebit
Common Stock or vested Telebit options for any Merger Consideration delivered to
a public official pursuant to any abandoned property, escheat or similar law.

         The  Exchange  Agent  will pay in  exchange  for any  lost,  stolen  or
destroyed certificates of Telebit Common Stock or Vested Option Agreements, upon
the  making of an  affidavit  of that fact by the  holder  thereof,  the  Merger
Consideration.  Cisco may,  however,  require the owner of such lost,  stolen or
destroyed  certificates  or  Vested  Option  Agreements  to  deliver  a bond  of
indemnity  against  any claim  that may be made  against  Cisco,  Telebit or the
Exchange  Agent with respect to the  certificates  or Vested  Option  Agreements
alleged to have been lost, stolen or destroyed.


                                      -35-


                  HOLDERS OF TELEBIT COMMON STOCK CERTIFICATES
                     OR VESTED OPTION AGREEMENTS SHOULD NOT
                   SUBMIT THEIR CERTIFICATES OR VESTED OPTION
                             AGREEMENTS FOR EXCHANGE
                     UNTIL THEY HAVE RECEIVED THE LETTER OF
                 TRANSMITTAL AND INSTRUCTIONS REFERRED TO ABOVE.

OPERATIONS FOLLOWING THE MERGER

         Following   the  Merger  and   subject  to  the  effect  of  the  Asset
Transactions,  Telebit will continue its operations as a wholly-owned subsidiary
of Cisco.  Consequently,  current Telebit  shareholders  will have no continuing
interest in the Company.  Following  consummation of the Merger there will be no
public trading market for the Telebit Common Stock, and the Telebit Common Stock
will be deregistered under the Exchange Act.

         Upon  consummation  of the Merger,  the  Articles of  Incorporation  of
Merger Sub as in effect  immediately prior to consummation of the Merger,  shall
be the Articles of Incorporation of the surviving corporation, provided that the
Articles of the surviving corporation shall be amended to change the name of the
surviving  corporation  to a  name  other  than  Telebit  or  any  name  closely
resembling Telebit.  Further, the Bylaws of Merger Sub, as in effect immediately
prior to  consummation  of the  Merger,  shall be the  Bylaws  of the  surviving
corporation.  Upon consummation of the Merger, the members of Merger Sub's board
of directors  will become the directors of Telebit.  The membership of the Board
of Directors of Cisco will remain unchanged as a result of the Merger.

THE MERGER AGREEMENT

         Representations,   Warranties  and  Covenants.   The  Merger  Agreement
contains  various  representations  and  warranties  of the  parties,  including
representations  by Cisco,  Telebit and Merger Sub as to their  organization and
corporate power and, their  authority to enter into the Merger  Agreement and to
consummate  the Merger.  In  addition,  the Merger  Agreement  contains  various
additional  representations and warranties of Telebit, including representations
as to the absence of certain material undisclosed liabilities and changes in its
business.  Such  representations and warranties will not survive consummation of
the Merger.

         Under the terms of the Merger  Agreement,  for the period from the date
of the Merger  Agreement and continuing  until the earlier of the termination of
the Merger  Agreement or the Effective  Time,  Telebit has agreed (except to the
extent  expressly  contemplated  by the Merger  Agreement  or as consented to in
writing  by Cisco) to: (i) carry on its and its  subsidiaries'  business  in the
usual, regular and ordinary course in substantially the same manner as conducted
prior  to  execution  of  the  Merger  Agreement;  (ii)  pay  and to  cause  its
subsidiaries to pay debts and taxes when due subject to good faith disputes over
such debts or taxes and to pay or perform other  obligations when due; (iii) use
its reasonable  efforts  consistent  with past practice and policies to preserve
intact  its  and  its  subsidiaries'  present  business  organizations,  use its
reasonable  efforts consistent with past practice to keep available the services
of its and its  subsidiaries'  present  officers and key  employees  and use its
reasonable  efforts  consistent  with  past  practice  to  preserve  its and its
subsidiaries' relationships with customers, suppliers, distributors,  licensors,
licensees,  and others having business dealings with it or its subsidiaries,  to
the end that its and its subsidiaries'  goodwill and ongoing businesses shall be
unimpaired at the Effective Time; (iv) use reasonable  efforts to insure that at
the Effective  Time its cash and cash  equivalent  balance equals or exceed $3.5
million;  and (v) use, in the period  prior to the  Effective  Time,  reasonable
efforts to meet the product  development  schedule for its


                                      -36-


MICA-based products. Telebit has also agreed to use its best efforts to promptly
notify Cisco of any event or occurrence not in the ordinary course of its or its
subsidiaries'  business,  and of any event which could reasonably be expected to
have a material adverse effect on Telebit. In addition,  Telebit has agreed that
it will not, among other things,  do, cause or permit any of the  following,  or
allow, cause or permit any of its subsidiaries to do, cause or permit any of the
following,  without the prior written consent of Cisco:  (i) cause or permit any
amendments to its Articles of Incorporation or Bylaws,  as amended;  (ii) issue,
deliver, sell, authorize or propose the issuance, delivery, sale of, purchase or
propose  the  purchase  of,  any  shares  of its  capital  stock  or  securities
convertible into, or subscriptions,  rights,  warrants or options to acquire, or
other agreements or commitments of any character obligating it to issue any such
shares or other  convertible  securities,  other than the  issuance of shares of
Telebit  Common  Stock  pursuant to the exercise of stock  options,  warrants or
other rights  therefor  outstanding  as of the date of the Merger  Agreement and
other than issuances  under the Telebit ESPP in the ordinary  course of business
consistent with past practice;  (iii) accelerate,  amend or change the period of
exercisability  or vesting of options or other rights  granted under the Telebit
Stock  Option Plans or  authorize  cash  payments in exchange for any options or
other rights  granted under any such plan;  (iv) except in  connection  with the
Asset Transactions,  enter into any contract or commitment, or violate, amend or
otherwise  modify or waive any of the terms of any of its contracts,  other than
in the ordinary course of business consistent with past practice and in no event
shall such contract, commitment,  amendment, modification or waiver be in excess
of $1,000,000; (v) except in connection with the Asset Transactions,  enter into
or amend any agreements  pursuant to which any other party is granted  exclusive
marketing or other exclusive  rights of any type or scope with respect to any of
its  products  or  technology;   (vi)  except  in  connection   with  the  Asset
Transactions,  sell,  lease,  license or otherwise dispose of or encumber any of
its properties or assets which are material,  individually  or in the aggregate,
to its and its subsidiaries' business,  taken as a whole, except in the ordinary
course of business  consistent with past practice;  (vii) incur any indebtedness
for borrowed money or guarantee any such  indebtedness or issue or sell any debt
securities  or guarantee  any debt  securities  of others except in the ordinary
course  of  business  consistent  with  past  practice;  (viii)  enter  into any
operating lease,  other than in the ordinary course of business  consistent with
past practice;  (ix) pay, discharge or satisfy in an amount in excess of $10,000
in any one case or $100,000 in the aggregate, any claim, liability or obligation
(absolute,  accrued,  asserted or unasserted,  contingent or otherwise)  arising
other than (a) in the  ordinary  course of  business,  other  than the  payment,
discharge  or  satisfaction  of  liabilities  reflected  or reserved  against in
Telebit's  financial  statements,  (b) the payment of the  transaction  expenses
associated with the  transactions  contemplated by the Merger  Agreement and the
Asset Transactions and (c) in connection with the Asset  Transactions;  (x) make
any capital  expenditures,  capital additions or capital  improvements except in
the  ordinary  course  of  business  and  consistent  with past  practice;  (xi)
materially  reduce the amount of any  material  insurance  coverage  provided by
existing insurance policies;  (xii) adopt or amend any employee benefit or stock
purchase or option plan,  execute or amend any employment  agreement with any of
Telebit's  officers  (including  Telebit's  employment  agreement  with James D.
Norrod),  or hire any new  director  level or officer  level  employee,  pay any
special bonus or special  remuneration to any employee or director,  or increase
the salaries or wage rates of its  employees  other than  increases  paid to its
non-officer  employees in the ordinary  course of business  consistent with past
practice;  (xiii) grant any severance or termination  pay (a) to any director or
officer  or (b) to any other  employee  except (1)  payments  made  pursuant  to
standard written  agreements  outstanding on the date of the Merger Agreement or
(2) grants which are made in the ordinary  course of business in accordance with
its standard  past  practice;  (xiv)  commence a lawsuit  other than (a) for the
routine collection of bills, (b) in such cases where it in good faith determines
that  failure to commence  suit would  result in the  material  impairment  of a
valuable aspect of its business,  provided, that it consults with Cisco prior to
the filing of such a suit,  or (c) for a breach of the Merger  Agreement  or the
Confidentiality  Agreement;  (xv)  acquire  or agree to  acquire  by  merging or
consolidating  with, or by purchasing a substantial portion of the assets of, or
by any other manner, any business or any corporation,  partnership,  association
or other business  organization  or division  thereof,  or


                                      -37-



otherwise   acquire  or  agree  to  acquire  any  assets  which  are   material,
individually or in the aggregate, to its and its subsidiaries'  business,  taken
as a whole  or  acquire  or  agree  to  acquire  any  equity  securities  of any
corporation, partnership, association or business organization; (xvi) other than
in the  ordinary  course of business  or with  respect to matters  disclosed  to
Cisco, make or change any material election in respect of taxes, adopt or change
any accounting  method in respect of taxes,  file any material tax return or any
amendment to a material tax return, enter into any closing agreement, settle any
claim or assessment  in respect of taxes,  or consent to any extension or waiver
of the  limitation  period  applicable  to any claim or assessment in respect of
taxes; (xvii) give all notices and other information required to be given to the
employees of Telebit,  any collective  bargaining unit representing any group of
employees of Telebit,  and any applicable  government  authority  under the WARN
Act,  the  National  Labor  Relations  Act,  the  Internal   Revenue  Code,  the
Consolidated Omnibus Budget  Reconciliation Act, and any other applicable law in
connection with the Transactions  provided for in the Merger Agreement;  (xviii)
revalue any of its assets,  including without  limitation writing down the value
of  inventory  or writing  off notes or  accounts  receivable  other than in the
ordinary course of business;  or (xix) take, or agree in writing or otherwise to
take, any of the actions  described in (i) through  (xviii) above, or any action
which would make any  representations  or warranties of Telebit contained in the
Merger  Agreement  untrue or  incorrect or prevent it from  performing  or cause
Telebit not to perform its covenants  thereunder.  Provided,  however,  that the
foregoing covenants shall not be interpreted to prohibit Telebit from taking any
action with respect to the  Purchased  Assets,  the Assumed  Liabilities  or the
Business (as such terms are defined in the Asset  Purchase  Agreement  and below
under the  caption  "The Asset  Transactions  --Assets  to be Sold")  that would
otherwise be  contemplated  or permitted with respect thereto under the terms of
the Asset Purchase Agreement.

         No Solicitation of Takeover  Proposal.  Telebit has further agreed that
Telebit and its  subsidiaries  and the officers,  directors,  employees or other
agents of Telebit and its  subsidiaries  will not,  directly or indirectly:  (i)
take any action to solicit, initiate or encourage any Takeover Proposal (defined
below) or (ii)  subject  to the  terms of the  immediately  following  sentence,
engage in negotiations with, or disclose any nonpublic  information  relating to
Telebit or any of it subsidiaries to, or afford access to the properties,  books
or records of Telebit or any of its subsidiaries to, any person that has advised
Telebit  that  it may be  considering  making,  or that  has  made,  a  Takeover
Proposal; provided, that the foregoing shall not prohibit the Telebit Board from
taking and  disclosing  to Telebit's  shareholders  a position with respect to a
tender offer  pursuant to Rules 14d-9 and 14e-2  promulgated  under the Exchange
Act.  Notwithstanding  the  immediately  preceding  sentence,  if an unsolicited
Takeover Proposal, or an unsolicited written expression of interest that Telebit
reasonably  expects to lead to a Takeover  Proposal,  shall be  received  by the
Telebit  Board,  then,  to the extent the Telebit  Board  believes in good faith
(after  consultation  with its financial  advisor)  that such Takeover  Proposal
would,  if  consummated,  result in a  transaction  more  favorable to Telebit's
shareholders  from a financial point of view than the transactions  contemplated
by the  Merger  Agreement  (any  such more  favorable  Takeover  Proposal  being
referred to herein as a "Superior Proposal") and the Telebit Board determines in
good faith  after  consultation  with  outside  legal  counsel  that it would be
inconsistent with the Board's fiduciary duties to shareholders  under applicable
law,  Telebit  and  its  officers,  directors,  employees,  investment  bankers,
financial advisors, attorneys, accountants and other representatives retained by
it may furnish in connection  therewith  information and take such other actions
as are consistent with the fiduciary  obligations of the Telebit Board, and such
actions shall not be considered a breach of the Merger Agreement; provided, that
in each such event Telebit  notifies Cisco of such  determination by the Telebit
Board and provides Cisco with a true and complete copy of the Superior  Proposal
received  from such third party,  if the Superior  Proposal is in writing,  or a
complete  written summary thereof,  if it is not in writing,  and provides Cisco
with all documents containing or referring to non-public  information of Telebit
that are supplied to such third party; provided,  further, that: (i) the Telebit
Board has determined, with the advice of Telebit's investment bankers, that such
third  party  is  capable  of  making  a  Superior  Proposal  upon  satisfactory
completion of such third party's review of the


                                      -38-


information supplied by Telebit; (ii) the third party has stated that it intends
to make a Superior  Proposal;  (iii)  Telebit  may not  provide  any  non-public
information  to any such  third  party if it has not  prior to the date  thereof
provided such information to Cisco or Cisco's representatives;  and (iv) Telebit
provides such  non-public  information  pursuant to a  non-disclosure  agreement
substantially  the same as or  otherwise at least as  restrictive  on such third
party as the  Confidentiality  Agreement is on Cisco;  provided,  however,  that
Telebit  shall  not,  and  shall  not  permit  any of its  officers,  directors,
employees or other  representatives to agree to or endorse any Takeover Proposal
unless Telebit shall have terminated the Merger  Agreement and paid to Cisco all
amounts payable to Cisco pursuant to the Merger Agreement. Telebit will promptly
notify  Cisco  after  receipt of any  Takeover  Proposal  or any notice that any
person is considering  making a Takeover  Proposal or any request for non-public
information  relating to Telebit or any of its subsidiaries or for access to the
properties, books or records of Telebit or any of its subsidiaries by any person
that has advised Telebit that it may be considering  making, or that has made, a
Takeover  Proposal and will keep Cisco fully  informed of the status and details
of  any  such  Takeover  Proposal  notice,  request  or  any  correspondence  or
communications  related thereto and shall provide Cisco with a true and complete
copy  of  such  Takeover   Proposal   notice   request  or   correspondence   or
communications  related  thereto,  if it is in  writing,  or a complete  written
summary thereof, if it is not in writing.  For purposes of the Merger Agreement,
"Takeover  Proposal"  means any offer or  proposal  for,  or any  indication  of
interest in, a merger or other business combination  involving Telebit or any of
its subsidiaries or the acquisition of any significant  equity interest in, or a
significant portion of the assets of, Telebit or any of its subsidiaries,  other
than the  transactions  contemplated  by the  Merger  Agreement,  provided  that
neither the execution of the Asset Purchase  Agreement nor  consummation  of the
Asset Transactions nor the disclosure of information  regarding Telebit to Cisco
under the Asset Purchase  Agreement  shall be deemed to be a breach of Telebit's
obligations under the Merger Agreement.

         Conditions to the Merger. Each party's respective  obligation to effect
the Merger is subject to, among other  things,  the approval and adoption of the
Merger  Agreement  and approval of  consummation  of the Merger by the requisite
vote of the  shareholders of Telebit,  the Commission  having approved the Proxy
Statement prior to distribution of the Proxy Statement to Telebit  shareholders,
and the  satisfaction  prior to the Effective Time of the  additional  following
conditions:  (i)  the  absence  of any  injunction  or  other  legal  action  or
regulatory  restraint or prohibition  preventing  consummation  of the Merger or
rendering  consummation of the Merger illegal,  nor shall any proceeding brought
by an  administrative  agency or commission or other  governmental  authority or
instrumentability,  foreign or domestic, seeking any of the foregoing be pending
and (ii) all approvals, waivers and consents imposed by, any governmental entity
necessary for  consummation  of or in connection with the Merger and the several
transactions  contemplated  by the Merger  Agreement,  including such approvals,
waivers and consents as may be required under the Securities  Act, and the rules
and  regulations  of the Commission  thereunder,  under state Blue Sky laws, and
under the HSR Act shall have been obtained.

         The  obligations  of Telebit to effect the Merger are subject to, among
other things,  the satisfaction at or prior to the Effective Time of each of the
following   conditions,   unless   waived  in  writing  by   Telebit:   (i)  the
representations  and warranties of Cisco and Merger Sub in the Merger  Agreement
shall be true and correct in all  material  respects on and as of the  Effective
Time as though such  representations  and warranties were made on and as of such
time;  (ii)  Cisco and  Merger  Sub shall have  performed  and  complied  in all
material  respects with all covenants,  obligations and conditions of the Merger
Agreement required to be performed and complied with by them as of the Effective
Time;  and (iii) Telebit shall have received a certificate to such effect signed
on behalf of Cisco by its President and Chief Financial Officer.

         The  obligations  of Cisco and  Merger  Sub to effect  the  Merger  are
subject to, among other things,  the  satisfaction  at or prior to the Effective
Time of each of the  following  conditions,  unless  waived in


                                      -39-


writing by Cisco:  (i)(a) the  representations  and warranties of Telebit in the
Merger Agreement shall be true and correct in all material respects on and as of
the Effective Time as though such  representations  and warranties  were made on
and as of such time,  (b)  Telebit  shall have  performed  and  complied  in all
material  respects with all covenants,  obligations and conditions of the Merger
Agreement  required to be performed  and complied with by it as of the Effective
Time and (c) Cisco shall have  received a  certificate  to such effect signed on
behalf of Telebit by its President and Chief Financial Officer; (ii) Cisco shall
have been furnished with evidence  satisfactory to it of the consent or approval
of those persons whose consent or approval shall be required in connection  with
the Merger under any material  contract of Telebit or any of its subsidiaries or
otherwise  (after giving effect to the  transactions  contemplated  by the Asset
Purchase  Agreement),  except where the failure to obtain such consent would not
have a material adverse effect on Telebit; (iii) no temporary restraining order,
preliminary  or  permanent  injunction  or other  order  issued  by any court of
competent   jurisdiction  or  other  legal  or  regulatory  restraint  provision
materially  limiting or restricting Cisco's conduct or operation of the business
of Telebit and its  subsidiaries,  following  the Merger (after giving effect to
the  transactions  contemplated  by the Asset  Purchase  Agreement)  shall be in
effect,  nor  shall  any  proceeding  brought  by an  administrative  agency  or
commission  or other  governmental  entity,  domestic  or  foreign,  seeking the
foregoing be pending;  (iv) there shall not have  occurred any material  adverse
change in the condition (financial or otherwise),  properties, assets (including
intangible assets), liabilities,  business, operations, results of operations or
prospects of Telebit and its subsidiaries,  taken as a whole provided,  however,
that any adverse  effect on revenues or gross  margins of Telebit (or the direct
consequences  thereof)  following  the  date of the  Merger  Agreement  which is
attributable to a delay of,  reduction in or cancellation or change in the terms
of product orders by customers of Telebit shall not be deemed a material adverse
effect;  (v) certain  employees of Telebit shall have accepted  employment  with
Cisco and shall have entered into employment  agreements with Cisco as described
in the  Merger  Agreement;  and (vi) the  closing  of the Asset  Sale shall have
occurred.

         Closing. As promptly as practicable after the satisfaction or waiver of
the  conditions set forth in the Merger  Agreement,  Merger Sub and Telebit will
file an  Agreement  of Merger with the  Secretary  of State of  California.  The
Merger will become effective upon such filing. It is anticipated that,  assuming
all  conditions  are met, the Merger will occur and a closing will be held on or
before October 11, 1996.

         Termination,  Amendments  and  Waivers.  The  Merger  Agreement  may be
terminated  at any time prior to the  Effective  Time,  whether  before or after
approval by the Telebit shareholders:

                  (i)  by  the  mutual  consent duly  authorized by the Board of
         Directors of Cisco and Telebit;
    
                  (ii) by  either  Cisco or  Telebit  if,  without  fault of the
         terminating  party, the Merger is not consummated on or before December
         31, 1996 (or such later date that the parties may agree to in writing);
    
                  (iii)  by  Cisco,   if  (a)  Telebit   breaches   any  of  its
         representations,  warranties or obligations  under the Merger Agreement
         and such breach is not cured within ten (10)  business  days of receipt
         by Telebit of written  notice of such  breach;  (b) the  Telebit  Board
         shall have  withdrawn  or  modified  its  recommendation  of the Merger
         Agreement  or the Merger in a manner  adverse  to Cisco,  or shall have
         resolved to do any of the foregoing or (c) for any reason Telebit fails
         to call and hold the Special Meeting by November 15, 1996;
    
                  (iv) by  Telebit,  if  Cisco  breaches  any of its  respective
         representations,  warranties or obligations  under the Merger Agreement
         and such breach is not cured within ten (10) days following  receipt by
         Cisco of written notice of such breach;
    
    
                                          -40-
    
    
                  (v) by either Cisco or Telebit if a Trigger  Event (as defined
         below) or Takeover  Proposal (as defined  below under the caption "Fees
         and  Expenses;  Termination  Fee") shall have  occurred and the Telebit
         Board in  connection  therewith,  after  consultation  with  its  legal
         counsel,  withdraws or modifies its approval and  recommendation of the
         Merger  Agreement  and the Merger in a manner  adverse  to Cisco  after
         determining  that to cause Telebit to proceed with the Merger would not
         be  consistent  with  the  Telebit   Board's   fiduciary  duty  to  the
         shareholders of Telebit; or
    
                  (vi)  by  either  Cisco  or  Telebit  if  (a)  any   permanent
         injunction  or other  order of a court  or  other  competent  authority
         preventing  consummation of the Merger becomes final and  nonappealable
         or (b) any  required  approval  of the  shareholders  of Telebit is not
         obtained  by reason of the failure to obtain the  required  vote upon a
         vote held at a duly held meeting of  shareholders or at any adjournment
         thereof.

         Subject to the fees and  expenses  described  below  under the  caption
"Fees and Expenses;  Termination Fee," in the event of termination of the Merger
Agreement,  the  Merger  Agreement  shall  become  void  and  there  shall be no
liability  or  obligation  on the part of Cisco,  Merger Sub or Telebit or their
respective officers, directors, shareholders or affiliates, except to the extent
that such  termination  results  from the breach by a party hereto of any of its
representations,  warranties  or  covenants  set forth in the Merger  Agreement;
provided   that,  the   provisions  of  the  Merger   Agreement   pertaining  to
confidentiality,  expenses and  termination  fees shall remain in full force and
effect and survive any such termination.

         For the  purposes  of  defining  the  termination  rights  of Cisco and
Telebit,  as well as determining whether termination fees are payable by Telebit
to Cisco,  a  "Trigger  Event"  would  occur if any person  acquires  securities
representing  20% or more, or commences a tender or exchange offer following the
successful   consummation   of  which  the  offeror  and  its  affiliate   would
beneficially  own  securities  representing  20% or more, of the voting power of
Telebit;  provided,  however, a Trigger Event shall not be deemed to include the
acquisition by any person of securities  representing  20% or more of Telebit if
such  person has  acquired  such  securities  not with the  purpose nor with the
effect of changing or influencing the control of Telebit, nor in connection with
or as a participant in any transaction having such purpose or effect,  including
without  limitation  not in connection  with such person:  (i) making any public
announcement  with  respect  to the  voting  of such  shares at any  meeting  to
consider any merger, consolidation, sale of substantial assets or other business
combination or extraordinary  transaction  involving Telebit; (ii) making, or in
any way  participating  in, any  "solicitation"  of "proxies" (as such terms are
defined or used in  Regulation  14A under the  Exchange  Act) to vote any voting
securities of Telebit  (including,  without  limitation,  any such  solicitation
subject to Rule 14a-11 under the Exchange Act) or seeking to advise or influence
any person  with  respect to the voting of any  voting  securities  of  Telebit,
directly  or  indirectly,  relating  to a merger or other  business  combination
involving  Telebit or the sale or transfer of any material assets (excluding the
sale or  disposition  of assets in the ordinary  course of business) of Telebit;
(iii)  forming,  joining or in any way  participating  in any "group" within the
meaning of  Section  13(d)(3)  of the  Exchange  Act with  respect to any voting
securities  of Telebit,  directly or  indirectly,  relating to a merger or other
business  combination  involving Telebit or the sale or transfer of any material
assets  (excluding the sale or  disposition of assets in the ordinary  course of
business) of Telebit; or (iv) otherwise acting, alone or in concert with others,
to seek control of Telebit or to seek to control or influence the  management or
policies of Telebit.

         The Merger  Agreement  may be amended by Cisco and  Telebit at any time
before or after  approval  by the Telebit  and Merger Sub  shareholders,  except
that, after such approval, no amendment may be made which: (i) alters or changes
the amount or kind of  consideration to be received on conversion of the Telebit


                                      -41-


Common Stock;  (ii) alters or changes any term of the Articles of  Incorporation
of the surviving  corporation  to be effected by the Merger;  or (iii) alters or
changes  any of the  terms  and  conditions  of the  Merger  Agreement  if  such
alteration or change would adversely  affect the holders of Telebit Common Stock
or Merger Sub common stock.

         At any time  prior to the  Effective  Time,  either of Cisco or Telebit
may, to the extent  legally  allowed,  by execution of an  instrument in writing
signed on behalf of such party:  (i) extend the time for the  performance of any
of the obligations or acts of the other party set forth in the Merger Agreement;
(ii) waive any inaccuracies in the  representations  and warranties made to such
party in the Merger  Agreement  or in any  document  delivered  pursuant  to the
Merger  Agreement;  and (iii) waive  compliance  with any of the  agreements  or
conditions for the benefit of such party under the Merger Agreement.

         Fees and Expenses; Termination Fee. Subject to the provisions described
below  regarding  reimbursement  of expenses  and payment of  termination  fees,
whether or not the Merger is  consummated,  all costs and  expenses  incurred in
connection with the Merger Agreement and the transactions  contemplated  thereby
are to be paid  by the  party  incurring  such  expense,  except  that  expenses
incurred  in  connection  with  printing  the Proxy  Statement  and filing  fees
incurred  in  connection  with the Proxy  Statement  which  fees shall be shared
equally by Telebit and Cisco.

         In the  event  either  Telebit  or Cisco  shall  terminate  the  Merger
Agreement  on  account  of a  breach  of  the  representations,  warranties,  or
obligations,  which, in the case of Telebit shall not have been cured within ten
(10) business days receipt by Telebit of written notice of such breach,  and, in
the case of Cisco  shall not have been  cured  within  ten (10) days  receipt by
Cisco of written notice of such breach,  the breaching party shall reimburse the
nonbreaching  party for all of the out-of-pocket  costs and expenses incurred by
such  nonbreaching  party  in  connection  with  the  Merger  Agreement  and the
transaction  contemplated  thereby  (including  without  limitation the fees and
expenses of its  advisors,  accountants  and legal  counsel) up to an  aggregate
amount not to exceed $1 million.  Additionally,  if Cisco  terminates the Merger
Agreement because: (i) the Telebit Board withdrew or modified its recommendation
of the Merger Agreement or the Merger in a manner adverse to Cisco or shall have
resolved  to any of the  foregoing;  (ii)  Telebit  failed  to call and hold the
Special Meeting by November 15, 1996,  subject to certain  exceptions;  or (iii)
any required  approval of Telebit  shareholders  shall not have been obtained by
reason of the  failure  to obtain the  required  vote upon a vote duly held at a
duly held  meeting of Telebit  shareholders  or at any  adjournment  thereof and
there has not  occurred a Trigger  Event or a Takeover  Proposal,  then  Telebit
shall reimburse Cisco for all of the  out-of-pocket  costs and expenses incurred
by  Cisco  in  connection  with  the  Merger   Agreement  and  the  transactions
contemplated  thereby (including without limitation the fees and expenses of its
advisors,  accountants,  and legal  counsel)  up to an  aggregate  amount not to
exceed $1 million.


         In the event that:  (i) either Cisco or Telebit  terminates  the Merger
Agreement  following the occurrence of a Trigger Event or Takeover  Proposal (as
defined below) and either (a) the Telebit  Board,  after  consultation  with its
legal  counsel,  withdraws or modifies its  approval and  recommendation  of the
Merger  Agreement and the Merger in a manner adverse to Cisco after  determining
that to cause  Telebit to proceed with the Merger would not be  consistent  with
the Telebit  Board's  fiduciary duty to the  shareholders  of Telebit or (b) any
required approval of Telebit shareholders shall not have been obtained by reason
of the  failure  to  obtain  the  required  vote upon a vote held at a duly held
meeting of Telebit  shareholders,  or at any adjournment thereof,  and, prior to
the time of such  meeting  there  shall  have been (1) a Trigger  Event or (2) a
Takeover  Proposal,  which shall not have been  rejected by Telebit;  or (ii) if
Cisco terminates the Merger Agreement because Telebit fails to call and hold the
Special Meeting by November 15, 1996, and prior to the time of such  termination
there  shall  have been (a) a Trigger  Event or (b) a Takeover  Proposal,


                                      -42-


which shall not have been rejected by Telebit, then Telebit shall be required to
pay Cisco $8  million  and shall  reimburse  Cisco  for  out-of-pocket  expenses
incurred  by Cisco  in  connection  with the  Merger  Agreement  and the  Merger
(including   without   limitation   the  fees  and  expenses  of  its  advisors,
accountants,  and legal  counsel)  up to an  aggregate  amount  not to exceed $1
million.

         In the event that:  (i) either Cisco or Telebit  terminates  the Merger
Agreement because any required approval of Telebit  shareholders  shall not have
been  obtained by reason of the failure to obtain the required  vote upon a vote
held at a duly held  meeting  of  Telebit  shareholders,  or at any  adjournment
thereof,  and,  prior to the time of the  meeting  there  shall  have been (a) a
Trigger Event or (b) a Takeover Proposal, which at the time of the meeting shall
have been rejected by Telebit and not withdrawn by the third party or (ii) Cisco
shall terminate the Merger  Agreement  because Telebit shall have failed to call
and hold the Special  Meeting by November  15, 1996,  and,  prior to the time of
such  termination,  there shall have been (a) a Trigger  Event or (b) a Takeover
Proposal,  which  shall have been  rejected by Telebit,  then  Telebit  shall be
required to pay Cisco $3 million  and shall  reimburse  Cisco for  out-of-pocket
expenses  incurred  by Cisco in  connection  with the Merger  Agreement  and the
Merger (including,  without  limitation,  the fees and expenses of its advisors,
accountants  and legal  counsel) up to an  aggregate  amount not in excess of $1
million;  provided,  however,  that, in the event that any Takeover  Proposal or
Trigger Event is consummated  within six months of the later of: (i) termination
of the Merger Agreement and (ii) the payment of such expenses,  Telebit shall be
required to pay Cisco an additional $5 million.

         For the  purposes  of the  preceding  two  paragraphs:  (i) a "Takeover
Proposal" shall occur if there is an offer or proposal for, or any indication of
interest in (where such indication of interest has been disclosed  publicly),  a
merger or other business combination involving Telebit or the acquisition of 20%
or more of the  outstanding  shares of  capital  stock of Telebit or the sale or
transfer of any material assets  (excluding the sale or disposition of assets in
the ordinary course of business) of Telebit,  or any of its subsidiaries,  other
than the Merger or the Asset Sale; (ii)  "consummation"  of a Takeover  Proposal
shall occur on the date a written  agreement  is entered  into with respect to a
merger or other business combination involving Telebit or the acquisition of 20%
or more of the  outstanding  shares  of  capital  stock of  Telebit,  or sale or
transfer of any material assets  (excluding the sale or disposition of assets in
the  ordinary  course of  business  and the Asset Sale) of Telebit or any of its
subsidiaries;  and (iii)  "consummation"  of a Trigger  Event shall occur on the
date any person or any of its affiliates or associates  would  beneficially  own
securities  representing 20% or more of the voting power of Telebit  following a
tender or exchange offer.

         In the  event  that  either  Cisco or  Telebit  terminates  the  Merger
Agreement because any required approval of Telebit  shareholders  shall not have
been  obtained by reason of the failure to obtain the required  vote upon a vote
held at a duly held  meeting  of  Telebit  shareholders,  or at any  adjournment
thereof  and,  prior to the time of the  meeting  there  shall have been:  (i) a
Trigger  Event or (ii) a  Takeover  Proposal,  which at the time of the  meeting
shall have been  rejected  by Telebit and  withdrawn  by the third  party,  then
Telebit shall reimburse Cisco for all out-of-pocket  costs and expenses incurred
by Cisco in  connection  with the Merger  Agreement  and the Merger  (including,
without limitation, the fees and expenses of its advisors, accountants and legal
counsel)  up to an  aggregate  amount  not in  excess of $1  million;  provided,
however,  that,  in  the  event  any  Takeover  Proposal  or  Trigger  Event  is
consummated  within  seven (7)  months of the later of: (i)  termination  of the
Merger  Agreement  and (ii)  the  payment  of such  expenses,  Telebit  shall be
required to pay Cisco $8 million.

         For the purposes of the preceding paragraph:  (i) a "Takeover Proposal"
shall occur if there is an offer or proposal for, or any  indication of interest
in (where such indication of interest has been disclosed publicly),  a merger or
other business  combination  involving Telebit or the acquisition of 40% or more
of the outstanding shares of capital stock of Telebit or the sale or transfer of
any material assets (excluding the sale


                                      -43-


or disposition of assets in the ordinary course of business) of Telebit,  or any
of  its   subsidiaries,   other  than  the  Merger  or  the  Asset  Sale;   (ii)
"consummation"  of a  Takeover  Proposal  shall  occur  on the  date  a  written
agreement is entered into with respect to a merger or other business combination
involving Telebit or the public  announcement of the initiation of such a merger
or business  combination or the  acquisition  of 40% or more of the  outstanding
shares of capital  stock of Telebit,  or any sale or  transfer  of any  material
assets  (excluding the sale or  disposition of assets in the ordinary  course of
business and the Asset Sale) of Telebit;  and (iii)  "consummation" of a Trigger
Event  shall  occur on the  date  (a) any  person  or any of its  affiliates  or
associates  would  beneficially  own securities  representing 20% or more of the
voting  power of Telebit  following a tender or exchange or (b) Telebit  files a
Schedule  14D-9  with the  Commission  recommending  that the  Telebit  security
holders accept the tender offer.

         Indemnification and Insurance.  The Merger Agreement provides that from
and after the Effective Time, Cisco will, and will cause Telebit to,  indemnify,
defend  and hold  harmless  each  person  who was as of the  date of the  Merger
Agreement  or has been at any time  prior to the date  thereof,  or who  becomes
prior to the Effective Time, an officer, director,  employee or agent of Telebit
in respect of acts or omissions  occurring on or prior to the Effective Time, in
each case to the full extent such corporation is permitted under California law,
the  Telebit  Articles  of  Incorporation   or  Bylaws,   as  amended,   or  any
indemnification  agreement with Telebit  officers and directors to which Telebit
is a party,  in each  case as in  effect  on the date of the  Merger  Agreement.
Without limitation of the foregoing,  the Merger Agreement also provides that in
the event any such  indemnified  party is or becomes involved in any capacity in
any action,  proceeding or  investigation in connection with any matter relating
to the Merger Agreement or the transactions contemplated thereby occurring on or
prior to the  Effective  Time,  Cisco shall,  or shall cause  Telebit to, pay as
incurred such indemnified party's reasonable legal and other expenses (including
the cost of any investigation and preparation) incurred in connection therewith.

         The Merger  Agreement  also  provides  that,  for four years  after the
Effective  Time,  Cisco will  either:  (i) at all times  maintain  at least $500
million in cash,  marketable  securities and unrestricted  lines of credit to be
available to indemnify the present and former officers, directors, employees and
agents of Telebit against  certain  liabilities or (ii) cause Telebit to use its
best  efforts to cause to be  maintained  in effect for the benefit of Telebit's
directors and officers and other persons covered by Telebit's current directors'
and officers' liability insurance policies with respect to all matters occurring
on or prior to the Effective Time,  Telebit's current policies of directors' and
officers' liability insurance or substantially similar policies provided that in
satisfying this obligation, Cisco shall not be obligated to cause Telebit to pay
premiums in excess of 150% of the amount per annum that Telebit paid in its last
full fiscal year,  and if Telebit is unable to obtain the insurance so required,
Cisco shall obtain as much  insurance as possible for an annual premium equal to
such maximum amount.

         Deregistration  of Telebit Common Stock.  Following the Effective Time,
the  shares of  Telebit  Common  Stock  will  cease to be  registered  under the
Exchange Act and will cease to be publicly traded.


RELATED AGREEMENTS

         Voting Agreements

         In connection  with the Merger,  certain  shareholders  of Telebit have
entered into voting agreements dated as of July 21, 1996 with Cisco (the "Voting
Agreements").  The form of the Voting Agreements is attached as Exhibit B to the
Merger  Agreement  and is  incorporated  by reference  herein.  The terms of the
Voting Agreements provide:  (i) that such shareholders will not transfer (except
as may be specifically


                                      -44-


required by court order),  sell,  exchange,  pledge (except in connection with a
bona fide loan  transaction)  or  otherwise  dispose  of or  encumber  shares of
Telebit Common Stock beneficially owned by them, or any new shares of such stock
they may acquire,  at any time prior to the Expiration  Date (as defined below);
and (ii) that such  shareholders  will vote all shares of Telebit  Common  Stock
beneficially  owned by them in favor of (a) approval of the Merger Agreement and
consummation of the Merger and (b) approval of the Asset Purchase  Agreement and
consummation   of  the   Asset   Sale  and   against   any   proposal   for  any
recapitalization,  merger,  sale of assets or other business  combination (other
than the Merger and the Asset  Sale)  between  Telebit  and any person or entity
other than Cisco or any other action or agreement  that would result in a breach
of any covenant, representation or warranty or any other obligation or agreement
of Telebit under the Merger  Agreement or the Asset Purchase  Agreement or which
could result in any of the conditions to Telebit's  obligations under the Merger
Agreement  or the Asset  Purchase  Agreement  not being  fulfilled.  Such Voting
Agreements are accompanied by irrevocable proxies whereby such shareholders have
provided to Cisco the right to vote their  shares on the  proposals  relating to
the Merger  Agreement,  the Merger,  the Asset Purchase  Agreement and the Asset
Sale at the Special Meeting and any competing proposal at a Telebit  shareholder
meeting.  Holders of  approximately  7.2% (exclusive of any shares issuable upon
the  exercise of options held by such  holders) of the shares of Telebit  Common
Stock  entitled  to  vote  at the  Special  Meeting  have  entered  into  Voting
Agreements  and  irrevocable  proxies.  The Voting  Agreements and proxies shall
terminate  the  earlier to occur of: (i) such date and time as the Merger  shall
become  effective  in  accordance  with the terms and  provisions  of the Merger
Agreement  and (ii) six  months  after  the date of  termination  of the  Merger
Agreement,  unless the Merger  Agreement  shall have been  terminated by (a) the
mutual  consent duly  authorized by the Board of Directors of Cisco and Telebit;
(b) Telebit, if Cisco breaches any of its respective representations, warranties
or  obligations  under the Merger  Agreement and such breach is not cured within
ten (10) days following  receipt by Cisco of written  notice of such breach;  or
(c) either Cisco or Telebit,  if any  permanent  injunction  or other order of a
court or other competent authority preventing consummation of the Merger becomes
final and nonappealable (the "Expiration Date").

         Stock Option Agreement

         Pursuant to that certain stock option  agreement,  dated as of July 21,
1996, by and between Cisco and Telebit (the "Stock Option Agreement"), a copy of
which is  attached  as  Exhibit C to Merger  Agreement  and is  incorporated  by
reference herein, Cisco was granted the right, under certain  circumstances,  to
acquire up to 2,071,000  shares (the "Cisco  Option") of authorized but unissued
shares  of  Telebit   Common   Stock  (the   "Telebit   Shares")   (constituting
approximately  fifteen percent (15%) of the outstanding shares of Telebit Common
Stock) at a price,  payable in cash, of $13.35 per share (the "Exercise Price");
provided  however,  that in the event  either (i) Telebit and Cisco shall at any
time  agree to an  increase  in the  Merger  Consideration  per share of Telebit
Common Stock  payable in the Merger (as  evidenced by the execution of a written
definitive agreement providing for such increased price), or (ii) Cisco shall at
any time  following  the date  hereof  commence a tender or  exchange  offer for
Telebit  Common Stock at a price per share of Telebit  Common Stock greater than
the Merger  Consideration  (as evidenced by the filing of a Schedule  14D-1 with
the  Securities  and  Exchange  Commission),   then  the  Exercise  Price  shall
automatically  be increased to such higher  agreed or offered price per share of
Telebit Common Stock.  Pursuant to the terms of the Stock Option Agreement,  the
type and number of  securities  subject to the Cisco  Option,  and the price per
share,  shall be adjusted in the event of any change in Telebit  Common Stock by
reason of certain events, including recapitalizations, combinations, exchange of
shares or the like. In the event Telebit enters into certain types of agreements
involving the merger of Telebit,  or sale of substantially  all of the assets of
Telebit,  such agreements must provide that upon consummation of any such merger
or sale that Cisco shall receive  consideration for each share of Telebit Common
Stock with  respect to which the Cisco Option has not been  exercised,  equal to
the amount of  consideration a holder of Telebit Common Stock would receive less
the Exercise Price.  The Stock Option  Agreement could have the effect of making
an  acquisition  of


                                      -45-


Telebit by a third party more costly  because of the need to acquire the Telebit
Shares in any such transaction.

         The Stock Option  Agreement  is  exercisable  by Cisco,  in whole or in
part, at any time or from time to time after any event occurs which would permit
Cisco to terminate the Merger  Agreement and recover an $8 million or $3 million
termination  fee  and  out-of-pocket   costs  and  expenses  described  in  "The
Merger--Fees  and Expenses,  Termination Fee" and  "Termination,  Amendments and
Waivers." The Cisco Option will terminate upon the earlier of: (i) the Effective
Time; (ii) the termination of the Merger Agreement  pursuant to its terms (other
than a termination in connection  with which Cisco is entitled to the payment of
a  termination  fee and  out-of-pocket  costs  and  expenses);  (iii)  180  days
following any termination of the Merger Agreement in connection with which Cisco
is entitled  to the payment of a  termination  fee and  out-of-pocket  costs and
expenses  (or, if at the  expiration  of such 180-day  period,  the Cisco Option
cannot be exercised by reason of any applicable judgment,  decree, order, law or
regulation,  ten (10) business days after such impediment to exercise shall have
been  removed or shall have become  final and not subject to appeal),  but in no
event later than July 21, 1998; or (iv) 210 days  following any  termination  of
the Merger  Agreement in connection with which Cisco is entitled to payment of a
termination fee and  out-of-pocket  costs and expenses (or, if at the expiration
of such 210-day  period,  the Cisco Option  cannot be exercised by reason of any
applicable judgment,  decree,  order, law or regulation,  ten (10) business days
after such  impediment to exercise  shall have been removed or shall have become
final and not  subject to  appeal,  but in no event  later than July 21,  1998).
Notwithstanding the foregoing, the Cisco Option may not be exercised if Cisco is
in  material  breach of any of its  representations,  warranties,  covenants  or
agreements contained in the Stock Option Agreement or in the Merger Agreement or
the Confidentiality Agreement.

         Under the terms of the Stock Option Agreement, at any time during which
the Cisco Option is exercisable (the "Repurchase  Period"),  Cisco has the right
to require  Telebit (or any successor  entity  thereof) to repurchase from Cisco
all or any part of the  Cisco  Option,  and  Telebit  (or any  successor  entity
thereof)  has the right to require  Cisco to sell to Telebit (or such  successor
entity)  all or any  part  of the  Cisco  Option,  at the  price  set  forth  in
subparagraph (i) below.  Also, at any time prior to July 21, 1998, Cisco has the
right to require  Telebit (or any successor  entity  thereof) to repurchase from
Cisco,  and Telebit (or any successor  entity  thereof) has the right to require
Cisco to sell to  Telebit  (or such  successor  entity),  all or any part of the
Telebit Shares  purchased by Cisco pursuant to the Cisco Option at the price set
forth in subparagraph (ii) below:

                  (i) The difference  between the Market/Tender  Offer Price (as
         defined  below) for shares of Telebit  Common  Stock as of the date the
         requesting party gives notice ("Notice Date") of its intent to exercise
         its rights and the Exercise Price,  multiplied by the number of Telebit
         Shares  purchasable  pursuant to the Cisco Option,  or portion thereof,
         but only if the  Market/Tender  Offer Price exceeds the Exercise Price.
         The "Market/Tender  Offer Price" means the higher of: (a) the price per
         share  offered as of the Notice Date pursuant to any tender or exchange
         offer or other Takeover Proposal that was made prior to the Notice Date
         and not  terminated  or  withdrawn  as of the Notice Date (the  "Tender
         Price")  or (b) the  average  of the  closing  sale  price of shares of
         Telebit  Common  Stock  on  Nasdaq  for  each of the ten  trading  days
         immediately preceding the Notice Date (the "Market Price").

                  (ii) The  Exercise  Price  paid by Cisco  for  Telebit  Shares
         acquired  pursuant to the Cisco Option plus the difference  between the
         Market/Tender  Offer  Price  and the  Exercise  Price,  but only if the
         Market/Tender   Offer  Price  is  greater  than  the  Exercise   Price,
         multiplied by the number of Telebit  Shares so purchased.  For purposes
         of this clause (ii),  the Tender Offer Price shall be the


                                      -46-

         highest price per share offered pursuant  to a tender or exchange offer
         or other Takeover Proposal during the Repurchase Period.

         Notwithstanding  the  foregoing,  the right of Telebit or any successor
thereof to require  Cisco to sell the Cisco  Option or the Telebit  Shares shall
not be  exercisable  unless  Telebit  shall  have  consummated  the  transaction
provided by a Takeover Proposal or Telebit's shareholders shall have transferred
their shares of Telebit  Common Stock  pursuant to a tender or exchange offer or
other Takeover Proposal.

         Subsequent to the  termination  of the Merger  Agreement,  Cisco may by
written notice  ("Registration  Notice")  request  Telebit to register under the
Securities  Act all or any  part of the  Telebit  Shares.  Telebit  may,  at its
option,  purchase such shares ("Registrable  Shares") at their market price (the
per share average of the closing sale price of Telebit's  Common Stock on Nasdaq
for each of the ten trading days immediately  preceding the Registration Notice)
within ten  business  days  after the  receipt of the  Registration  Notice.  If
Telebit  does not elect to  exercise  its  option to  purchase  the  Registrable
Shares,  it shall use its best efforts to register the  unpurchased  Registrable
Shares;  provided,  however,  (i) Cisco  shall not be  entitled  to more than an
aggregate of two effective registration  statements and (ii) Telebit will not be
required to file any such  registration  statement for a certain  period of time
when (a) Telebit is in possession of material  non-public  information  which it
reasonably  believes  would be  detrimental to be disclosed at such time and, in
the written  opinion of counsel to Telebit,  such  information  would have to be
disclosed if a  registration  statement  were filed at such time; (b) Telebit is
required under the Securities Act to include  audited  financial  statements for
any period in such registration  statement and such financial statements are not
yet  available  for  inclusion in such  registration  statement;  or (c) Telebit
determines,  in its reasonable judgment,  that such registration would interfere
with any financing,  acquisition or other material transaction involving Telebit
or any of its affiliates.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         In considering the  recommendation of the Telebit Board with respect to
the Merger,  shareholders  of Telebit should be aware that certain  officers and
directors of Telebit have interests in the Merger,  including  those referred to
below,  that presented them with potential  conflicts of interests.  The Telebit
Board was aware of these potential  conflicts and considered them along with the
other  matters  described in "The  Transactions--Reasons  for the  Transactions;
Recommendation of the Board of Directors."

         It is currently  anticipated  that Michael K. Ballard,  Executive  Vice
President,  Marketing of Telebit and a member of the Telebit  Board,  will enter
into an  employment  and  non-competition  agreement  with  Cisco for a position
comparable to his current position with Telebit. In addition, Telebit has agreed
to use its best efforts to ensure,  and it is a condition to closing the Merger,
that  certain  Telebit  employees  enter  into  employment  and  non-competition
agreements  with  Cisco.  See  "The   Merger--Related   Agreements--The   Merger
Agreement--Conditions to Merger."

         Messrs.  Norrod,  Ballard,  Cohen  and  Wilson  are  each  party  to an
employment agreement with Telebit.  Each of these employment agreements provides
for  the  acceleration  of  vesting  of  certain  of  such  executive  officer's
outstanding options to purchase shares of Telebit Common Stock upon consummation
of  a  Sale  Transaction  (as  defined  in  the  employment  agreements).   Upon
consummation  of the  Merger,  options to  purchase,  68,752,  20,755 and 11,631
shares of  Telebit  Common  Stock  held by Messrs.  Ballard,  Cohen and  Wilson,
respectively,  will  accelerate.  Mr. Norrod's  outstanding  options to purchase
Telebit Common Stock will be fully vested prior to  consummation  of the Merger.
In addition,  pursuant to the terms of the employment  agreements  with Telebit,
upon  consummation  of the Merger  Messrs.  Cohen and Wilson will be


                                      -47-


entitled to severance  payments  equal to  approximately  $208,000 and $189,000,
respectively, before tax and other withholdings.

         As of the Record Date,  the officers and directors of Telebit and their
affiliates owned an aggregate of 996,964 shares of Telebit Common Stock and will
be entitled to receive the Merger  Consideration with respect to such shares. In
addition,  certain of the Company's  officers hold options to purchase shares of
Telebit  Common  Stock and will be entitled to receive the Merger  Consideration
less the exercise  price of the option for each share of Common Stock covered by
the options. See "Security Ownership of Management and Principal  Shareholders."
Such persons will receive the same Merger  Consideration  per share as all other
shareholders  and,  other than the  acceleration  of certain  options  described
above, will not receive any special or additional consideration for their shares
of Telebit Common Stock or options.

         The Merger Agreement  provides that, from and after the Effective Time,
Cisco will cause Telebit,  to the fullest extent permitted under the laws of the
State of  California,  the Telebit  Articles  of  Incorporation  and Bylaws,  as
amended, or any  indemnification  agreement with Telebit officers and directors,
to indemnify and hold harmless each of Telebit's  current  officers,  directors,
employees or agents, or any person who becomes an officer, director, employee or
agent of  Telebit  prior to the  Effective  Time,  made,  in  respect of acts or
omissions  occurring on or prior to the  Effective  Time.  See "The  Merger--The
Merger Agreement--Indemnification and Insurance."

CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

         The following  discussion  summarizes the principal  federal income tax
consequences  of the Merger to holders  of Telebit  Common  Stock who are United
States persons within the meaning of Section 7701(a)(30) of the Internal Revenue
Code of 1986,  as amended (the  "Code").  This  discussion  does not address all
income tax considerations  that may be relevant to certain of these shareholders
in light of their particular circumstances, such as shareholders who are dealers
in  securities,  who do not hold the  Telebit  Common  Stock as a capital  asset
within the meaning of Section  1221 of the Code or who  acquired  their  Telebit
Common Stock in  connection  with stock  options or stock  purchase  plans or in
other  compensatory  transactions.  In  addition,  the tax  treatment of certain
holders of Telebit  Common  Stock  (including,  but not  limited  to,  insurance
companies, tax-exempt organizations,  financial institutions and persons subject
to the  alternative  minimum tax) may be affected by special rules not discussed
below.  ACCORDINGLY,  HOLDERS OF TELEBIT COMMON STOCK ARE URGED TO CONSULT THEIR
OWN TAX ADVISORS AS TO THE SPECIFIC TAX  CONSEQUENCES  OF THE MERGER,  INCLUDING
THE APPLICABLE FEDERAL,  STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE MERGER
TO THEM.

         Holders of Telebit Common Stock  generally will recognize  capital gain
or loss  equal to the  difference  between  the amount of cash  received  in the
Merger or pursuant to the  exercise of  dissenter's  rights and the adjusted tax
basis of the Telebit Common Stock exchanged therefor.  Such capital gain or loss
will be  long-term  capital  gain or loss if the  holding  period of the Telebit
Common Stock is more than one year.

         In  order  to avoid  "backup  withholding"  of  federal  income  tax on
payments  of  cash  received  in the  Merger  or  pursuant  to the  exercise  of
dissenter's rights, each Telebit shareholder generally must provide the payor of
such cash with the shareholder's correct taxpayer  identification number ("TIN")
on an Internal Revenue Service Form W-9 or an acceptable  substitute and certify
under penalties of perjury that such number is correct and that such shareholder
is not  subject to backup  withholding.  If a  shareholder  fails to provide the
correct  TIN or  certification,  and no  exemption  from backup  withholding 


                                      -48-


is available, cash received by that shareholder in the Merger or pursuant to the
exercise  of  dissenter's  rights  may be  subject  to backup  withholding  at a
thirty-one percent (31%) rate.


ACCOUNTING TREATMENT

         The Merger is expected to be accounted for under the purchase method of
accounting,  with Cisco as the acquiring  party,  in accordance  with  generally
accepted  accounting  principles.  Under the purchase method of accounting,  the
purchase  price  of  Telebit,  including  direct  costs of the  Merger,  will be
allocated  to the  assets  acquired  and  liabilities  assumed  based upon their
estimated fair values,  with any excess of the purchase price over the estimated
fair value of net assets acquired being recorded as goodwill.



                                      -49-

    

                             THE ASSET TRANSACTIONS


GENERAL

         The Asset Purchase Agreement sets forth certain  transactions  pursuant
to which  substantially  all of the assets,  and  liabilities of Telebit will be
sold to and assumed by Newco in  consideration  for the Notes. The discussion in
this Proxy  Statement  of the Asset Sale and the  description  of the  principal
terms  and  conditions  of the  Asset  Purchase  Agreement  are  subject  to and
qualified in their entirety by reference to the Asset Purchase Agreement, a copy
of which is attached to this Proxy  Statement as Appendix B and is  incorporated
by reference  herein.  Shareholders are urged to read the Asset Agreement in its
entirety.

ASSETS TO BE SOLD

         Pursuant to the terms of the Asset  Purchase  Agreement,  Telebit  will
sell, transfer, assign and deliver or cause to be sold, transferred, assigned or
delivered to Newco all of the assets,  properties and business of Telebit, other
than: (i) the MICA Assets and the MICA Trademark; (ii) all other Telebit patents
and patent  applications;  (iii) $3.5 million in cash; (iv) Telebit's  rights to
enforce any non-competition provision relating to the MICA Assets that may exist

under Telebit's current and former directors' and officers'  liability insurance
policies  (collectively,  the  "Excluded  Assets").  The  business and assets of
Telebit other than the Excluded Assets  constitute the "Business." The assets to
be sold by Telebit  (collectively,  the "Purchased Assets") are comprised of all
of the  operating  assets  related  to the  Business,  including:  (i) all  real
property and leases of, and other interests in, real property, together with all
buildings,  fixtures and improvements thereon; (ii) all personal property; (iii)
all  inventory,  including raw  materials,  work-in-process,  finished goods and
supplies;  (iv)  all  rights  under  contracts,  agreements,  licenses,  leases,

notes and other receivables;  (vi) all prepaid expenses and deposits;  (vii) all
cash and cash equivalents on hand and in banks in excess of $3.5 million; (viii)
all rights, claims, credits, causes of action or rights of set-off against third
parties  relating to the Purchased Assets  including  unliquidated  rights under
manufacturers'  and vendors'  warranties;  (ix) all  proprietary  rights  owned,
licensed or used in the  Business;  (x) all  transferable  licenses,  permits or
other governmental  authorizations  affecting or relating to the Business;  (xi)
all books, records,  files and papers,  whether in hard copy or computer format,
including without  limitation,  engineering  information,  sales and promotional
literature,  manuals  and data,  sales  and  purchase  correspondence,  lists of
present and former suppliers and customers, personnel and employment records and
any information  relating to tax imposed on the Purchased  Assets;  (xii) all of
the outstanding capital stock of Telebit's  subsidiaries and (xiii) all goodwill
associated with the Business or the Purchased  Assets together with the right to
represent to third parties that Newco is the successor to the Business.

         The acquisition by Newco of the Purchased  Assets is subject to Newco's
assumption  of  certain  specified  liabilities   (collectively,   the  "Assumed
Liabilities"), including, but not limited to: (i) all liabilities arising out of
or relating to the Business;  (ii) all  liabilities  and  obligations of Telebit
arising under Telebit's  contracts  related to the Business;  (iii) all warranty
claims or expenses of Telebit in respect of products  sold or services  rendered
by the Business  through the date the Asset Sale is  consummated  (the  "Closing
Date");  (iv) Telebit's  obligation to provide vacation time and vacation pay to
Telebit's  employees to the extent  accrued on or prior to the Closing Date; (v)
Telebit's   obligation  to  provide  severance  to  Telebit's   employees  whose
employment is  terminated  prior to or in connection  with



                                      -50-


consummation of the proposed Transactions;  (vi) all obligations and liabilities
arising  from any action,  suit,  investigation,  or  proceeding  relating to or
arising out of the Business or the Purchased  Assets;  (vii) all liabilities and
obligations relating to any products  manufactured or sold by the Business on or
prior to the Closing Date including without limitation warranty  obligations and
product  liability  claims;  (viii) all taxes of Telebit incurred on or prior to
the  Closing  Date;  and (ix) fifty  percent  (50%) of the fees and  expenses of
Telebit  including,  without  limitation,  fees and  expenses of legal  counsel,
accountants  and financial  advisors,  incurred in connection  with the proposed
Transactions and any liability of Telebit for taxes arising from or with respect
to the Asset Sale,  other than those  specified  below as Excluded  Liabilities.
Newco will not,  however,  assume any liability or obligation (i) relating to an
Excluded Asset arising after the Closing Date or (ii) fifty percent (50%), up to
an  aggregate  of  $550,000,  of the fees and  expenses  of Telebit  incurred in
connection  with the Asset Sale and the Merger and any  liability of Telebit for
taxes with respect to the Asset Sale (collectively, the "Excluded Liabilities").

PURCHASE PRICE

         The purchase price for the Purchased  Assets (the "Purchase  Price") is
the Secured Senior  Subordinated  Note due 2001 of Newco in the principal amount
of $31.5 million and the assumption of the Assumed  Liabilities.  In connection,
and simultaneously,  with the purchase and sale of the Purchased Assets, Telebit
will  purchase  3,500  shares of Newco's  newly  issued  Preferred  Stock for an
aggregated  purchase price of $3.5 million.  See "Related  Agreements--Preferred
Stock Purchase and Noteholder Rights Agreement."

THE ASSET PURCHASE AGREEMENT

         Representations, Warranties and Covenants. The Asset Purchase Agreement
contains  various  representations  and  warranties  of the  parties,  including
representations  by Telebit and Newco as to their  organization and authority to
enter into the Asset Purchase  Agreement and to consummate the Asset Sale.  Such
representations and warranties will not survive consummation of the Asset Sale.

         The  Asset  Purchase  Agreement  also  contains  various  covenants  of
Telebit.  Under the terms of the Asset Purchase  Agreement,  Telebit has agreed,
among  other  things,  that it will,  for the period  from the date of the Asset
Purchase  Agreement  and  continuing  until the  Closing  Date:  (i) conduct the
Business in the ordinary course consistent with past practice; (ii) use its best
efforts to preserve  intact the business  organization  and  relationships  with
third  parties of the  Business;  and (iii) keep  available  the services of the
present employees of the Business,  and that without limiting  foregoing it will
not,  from the date of the Asset  Purchase  Agreement  until the  Closing  Date:
(iv)(a) with respect to the  Business  acquire a material  amount of assets from
any other person, (b) sell, lease, license or otherwise dispose of any Purchased
Assets except pursuant to existing  contracts or commitments and in the ordinary
course  consistent  with past practice,  or (c) agree or commit to do any of the
foregoing; (v)(a) take or agree or commit to take any action that would make any
of its  representations or warranties  contained in the Asset Purchase Agreement
inaccurate  in any respect  at, or as of any time prior to, the Closing  Date or
(b) omit or agree or commit to omit to take any action  necessary to prevent any
such representation or warranty from being inaccurate in any respect at any such
time.  Telebit has also agreed that it will: (i)(a) with its subsidiaries,  file
all tax returns for periods  ending  prior to or  including  the Closing Date in
accordance with past practice and custom, except where the failure to do so does
not result in a material  increase in the amount of the Assumed  Liabilities and
except where to do so would result in material penalties to Telebit,  (b) timely
pay all taxes owed by it and each of its subsidiaries  (subject to reimbursement
by Newco to the extent prescribed in the Asset Purchase Agreement), except where
the  failure to do so would not result in a material  increase  in the amount of
the Assumed  Liabilities,  and (c) not, without the


                                      -51-


prior  consent of Newco,  make any new  elections  with  respect  to taxes,  any
changes in the current  elections with respect to taxes, or file any amended tax
return,  except  where  the  failure  to do so would not  result  in a  material
increase in the amount of Assumed  Liabilities  and would not result in material
penalties  to  Telebit;  (ii) keep $3.5  million  in cash and cash  equivalents,
except where to do so would cause a material  adverse effect;  and (iii) use all
reasonable  efforts to obtain all required  consents  from third parties and all
consents, authorizations or approvals from the governmental agencies referred to
in the Asset Purchase Agreement,  in each case in form and substance  reasonably
satisfactory to Newco. In addition, Telebit has agreed, among other things, that
it will: (i) use its best efforts to take all actions  necessary or desirable to
consummate the Asset Sale;  (ii) prepare and file a Proxy  Statement and a 13E-3
Transaction  Statement with the  Commission and cause the Proxy  Statement to be
mailed to the Telebit  shareholders;  (iii) maintain the  confidentiality of all
information  exchanged between it and Newco; (iv) notify Newco of (a) any notice
from a person  that  such  person's  consent  is  required  in  connection  with
consummation  of the Asset Sale,  (b) any notice from a  governmental  agency in
connection  with the Asset  Sale,  and (c) any  actions or claims  commenced  or
threatened  against  Telebit that relate to  consummation of the Asset Sale; and
(v) as soon as  practicable  after the Closing  Date,  eliminate  the use of all
trademarks,  tradenames,  service  marks and service names used in the Business,
other than the MICA  Trademark  and change its  corporate  name so as to bear no
resemblance to the name Telebit.

         Employees, Offers of Employment, Employee Benefit Plans. On or prior to
the Closing Date, Newco may at its sole discretion offer employment to employees
of the Business who have not been offered  employment  by Cisco  pursuant to the
Merger Agreement,  and who are "active employees" on the Closing Date; provided,
that Newco may  terminate at any time after the Closing Date the  employment  of
any   employee   who  accepts   such   offer.   See  "The   Merger--The   Merger
Agreement--Conditions  to the Merger." The term "active employee" shall mean any
person who, on the Closing  Date,  is actively  employed by Telebit or who is on
short-term  disability leave,  authorized leave of absence,  military service or
lay-off with recall rights as of the Closing Date (such inactive employees shall
be offered employment by Newco as of the date they return to active employment),
but shall exclude any other inactive or former employee including any person who
has been on long-term  disability leave or unauthorized  leave of absence or who
has terminated his or her  employment,  retired or died on or before the Closing
Date.  Any such offers shall be at such salary or wage and benefit levels and on
such other  terms and  conditions  as Newco  shall in its sole  discretion  deem
appropriate.  The  employees who accept and commence  employment  with Newco are
collectively referred to as the "Transferred  Employees." Telebit has agreed not
to take, any action that would impede,  hinder,  interfere or otherwise  compete
with Newco's effort to hire any Transferred  Employees.  In addition,  Newco has
agreed not to discuss or offer  employment  to the employees who will be offered
employment by Cisco pursuant to the Merger Agreement.

         As of the Closing Date, Newco shall adopt and assume Telebit's employee
plans and benefit arrangements on behalf of the Transferred Employees.  Newco or
one of its affiliates  will recognize all service of the  Transferred  Employees
with  Telebit  or  any  of  its  affiliates,  for  purposes  of  eligibility  to
participate in those employee  benefit plans in which the Transferred  Employees
are  enrolled by Newco or one of its  affiliates  immediately  after the Closing
Date.

         Conditions  to the Asset Sale.  Each party's  respective  obligation to
effect the Asset Sale is subject to,  among other  things,  the  approval of the
Asset Sale and the Merger by the requisite vote of the  shareholders  of Telebit
and the  satisfaction  prior to consummation of the Asset Sale of the additional
following  conditions:  (i) all of the  conditions to the closing of the Merger,
other than the closing of the Asset Sale,  shall have been  satisfied  or waived

         Indemnification.  The Asset  Purchase  Agreement  provides  that  Newco
shall, for a period of ten (10) years from the Closing Date,  indemnify and hold
harmless Telebit, any of its affiliates and the directors,  officers, employees,

                                      -53-


and provided further that Newco's liability for indemnification shall be reduced
by any amounts recovered by Telebit under any insurance policy.

         The Asset Purchase  Agreement  also provides that Telebit shall,  for a
period of ten (10) years from the Closing Date,  indemnify and hold harmless the
directors,  officers,  employees,  counsel  or  agents  of  Newco  or any of its
affiliates,  from and against any losses, claims,  demands,  actions,  proceeds,
damages,   liabilities  or  expenses  arising  out  of,  resulting  directly  or

         Termination;  Costs  and  Expenses;  Amendment  and  Waiver.  The Asset
Purchase  Agreement may be terminated at any time prior to  consummation  of the
Asset Sale:

                  (i) by the mutual written agreement of Telebit and Newco;

                  (ii) by either  Telebit  or Newco,  if,  without  fault of the
         terminating  party,  the Assets Sale shall not have been consummated on
         or before  December  31, 1996 (or such later date as may be agreed upon
         in writing by the parties hereto);

                  (iii) by either  Telebit or Newco if there shall be any law or

RELATED AGREEMENTS

         Preferred Stock Purchase and Noteholder Rights Agreement

         The Preferred Stock Purchase and Noteholder Rights Agreement sets forth
the terms and  conditions  on which  Telebit  will  purchase  3,500  shares (the
"Preferred  Shares") of Newco's  Class A Redeemable  Preferred  Stock,  $.01 par
value per share, for an aggregate purchase price of $3.5 million.  The Preferred
Stock Purchase and Noteholder Rights Agreement also sets forth the rights of the
holders of Newco's Secured Senior  Subordinated  Notes due 2001 (the "Notes") in
the aggregate principal amount of $31.5 million to be issued by Newco to Telebit
in connection with the financing of the Asset Sale. The discussion in this Proxy
Statement of the Preferred Stock, the Notes and the description of the principal
terms and  conditions  of the Preferred  Stock  Purchase and  Noteholder  Rights
Agreement  are subject to and  qualified  in their  entirety by reference to the
Preferred  Stock Purchase and Noteholder  Rights  Agreement,  a copy of which is
attached to this Proxy  Statement as Appendix C and is incorporated by reference
herein.  Shareholders  are  urged  to read  the  Preferred  Stock  Purchase  and
Noteholder Rights Agreement in its entirety.

         Preferred Stock.

         General

         The Preferred Stock will be non-voting, except as otherwise required by
law.  Holders of the  Preferred  Stock will be  entitled  to receive  cumulative
dividends at an annual rate of eight percent (8%) per share,  payable  quarterly
on the last day of September,  December, March and June of each year, commencing
December 31, 1996;  provided,  however,  that all accrued and unpaid  dividends,
whether  or not earned or  declared,  shall bear  interest  from the  applicable
payment date until paid at an annual rate of ten percent (10%) per share.

         Liquidation

         Upon any  liquidation,  dissolution or winding up of Newco, the holders
of the  Preferred  Stock shall be  entitled to receive  $1,000 per share plus an
amount equal to any  dividends  declared but unpaid on the  Preferred  Stock.  A
"Liquidation Event" is deemed to include: (i) any consolidation of Newco with or
merger of Newco into another  person or persons or any merger of another  person
or persons into Newco or any other transaction or series of related transactions
which  results  directly or  indirectly  in an aggregate  change in ownership or
control of more than thirty  percent (30%) of the voting  rights of  outstanding
voting equity  securities of Newco; (ii) any sale,  lease,  mortgage,  exchange,
transfer or other disposal of all or substantially all of the assets of Newco to
another  person or persons;  or (iii) the  acquisition by any person or persons,
other than James D.  Norrod,  directly or  indirectly,  of  securities  of Newco
representing  more than thirty percent (30%) of the voting rights of outstanding
voting equity securities of Newco.

         Full Mandatory Redemption

         Newco is  obligated  to redeem  all of the then  outstanding  Preferred
Stock on the earlier of September 30, 2001 or thirty (30) days after the closing
of an  initial  public  offering  of  its  common  stock  registered  under  the
Securities Act.


                                      -55-


         Partial Mandatory Redemption

         If at any time the Notes are not outstanding  while any Preferred Stock
is outstanding, then Newco is obligated to redeem: (i) for each fiscal year, the
number of whole shares  (rounding  downward)  of Preferred  Stock equal to fifty
percent  (50%) of its  Excess  Cash  Flow (as  defined  in the  Preferred  Stock
Purchase and Noteholder  Rights  Agreement) for such fiscal year,  divided by an
amount  equal to $1,000 per share  plus,  in the case of each  share,  an amount
equal to any dividends  declared but unpaid thereon,  computed to the applicable
redemption  date (the  "Redemption  Price")  (subject to  adjustment);  (ii) the
number of whole  shares  (rounding  downward)  of  Preferred  Stock equal to the
amount of proceeds received by Newco from any sale,  assignment,  lease or other
disposition of or voluntary  parting of control of a substantial  portion of its
assets  (each a  "Permitted  Disposition")  which,  during any fiscal  year when
combined  with  all  other  Permitted  Dispositions,  exceeds  $500,000  in  the
aggregate,  less the  applicable  costs and taxes payable by Newco in connection
therewith, divided by the Redemption Price; and (iii) the number of whole shares
(rounding  downward) of Preferred Stock equal to the amount of proceeds received
by Newco through (a) the issuance of voting securities (other than in an initial
public  offering)  which in the aggregate  exceeds $5 million in any year or (b)
the  incurrence of  indebtedness  for borrowed money which is subordinate to the
Senior  Debt (as  defined  below)  (each an  "Additional  Financing"),  less the
applicable costs and taxes payable by Newco in connection therewith,  divided by
the Redemption Price.

         Optional Redemption

         Newco may, at any time at its sole discretion,  redeem from the holders
of the  Preferred  Stock,  any or all of such  shares;  provided  that if  Newco
redeems less than all of the then  outstanding  shares of Preferred  Stock,  the
number of shares  redeemed from any one holder shall be  determined  pro rata in
relation to the aggregate number of shares of Preferred Stock then outstanding.

         The Notes.

         General

         The Notes will be subordinated  secured obligations of Newco limited to
an aggregate  principal amount of $31.5 million and will mature on September 30,
2001.  The Notes will be secured by, and entitled to the benefits of, a Security
Agreement to be executed  concurrently  with  issuance of the Notes  pursuant to
which  Newco  will  grant to  Telebit a  security  interest  in,  all of Newco's
inventory,  equipment,  accounts,  intellectual  property,  all other assets and
proceeds of the foregoing to secure the performance of its obligations under the
Notes.

         Interest Rate

         The Notes  will bear  interest  at the rate of eight  percent  (8%) per
annum,  payable  annually at December 31 of each year,  commencing  December 31,
1996.  Upon the  occurrence of an Event of Default (as defined  below)  interest
shall be payable  from the date of such  Event of  Default  on the whole  amount
remaining unpaid at the rate of ten percent (10%) per annum, until such Event of
Default has been cured or waived.


                                      -56-


         Subordination

         The Notes  will be  subordinated  and junior in right of payment to all
existing and future Senior Debt of Newco. The term "Senior Debt" shall mean: (i)
all  indebtedness of Newco for money borrowed from banks or other  institutional
lenders,  including any extension or renewals  thereof,  whether  outstanding on
July 21,  1996 or  thereafter  created  or  incurred,  which is not by its terms
subordinate  and junior to or on a parity with the Notes and which is  permitted
pursuant to the terms of the  Preferred  Stock  Purchase and  Noteholder  Rights
Agreement at the time it is created or incurred and (ii) all guaranties by Newco
which are not by their terms  subordinate  and junior to or on a parity with the
Notes of indebtedness of any of Newco's  subsidiaries if such indebtedness would
have been Senior Debt pursuant to the  provisions of clause (i) of this sentence
had it been indebtedness of Newco and which are permitted  pursuant to the terms
of Preferred Stock Purchase and Noteholder Rights Agreement at the time they are
made.

         Mandatory Prepayment in Full

         Upon the  occurrence of a Liquidity  Event (as defined  below) Newco is
obligated to prepay all of the Notes held by any holder,  at a prepayment  price
equal to the principal then  outstanding,  together with all interest accrued to
the  date  of  prepayment.  The  term  "Liquidity  Event"  shall  mean:  (i) any
consolidation of Newco with or merger of Newco into another person or persons or
any merger of another person or persons into Newco, or any other transactions or
series of related  transactions,  which  results  directly or  indirectly  in an
aggregate  change in the ownership or control of more than thirty  percent (30%)
of the voting rights of outstanding  voting equity securities of Newco; (ii) any
sale,  lease,  mortgage,  exchange,  transfer or other  disposition of assets of
Newco or its  subsidiaries  (excluding  any made in  connection  with the Senior
Debt) which,  when aggregated with any sales or other  dispositions of assets of
Newco,  results  in the  sale,  lease,  mortgage,  exchange,  transfer  or other
disposition of all or substantially all of the assets of Newco to another person
or persons;  (iii) the  acquisition  by any person,  other than James D. Norrod,
directly or  indirectly,  of securities of Newco  representing  more than thirty
percent (30%) of the voting rights of  outstanding  voting equity  securities of
Newco; (iv) a liquidation of Newco; or (v) the closing of Newco's initial public
offering.

         Mandatory Partial Prepayments

         At any time the Notes are  outstanding,  Newco is  obligated to prepay,
without  penalty or premium:  (i) within fifteen (15) days of the end of Newco's
fiscal year  (subject to  adjustment),  an amount of the  principal  amount then
outstanding  on the Notes equal to fifty  percent  (50%) of the Excess Cash Flow
for such fiscal year;  (ii) within fifteen (15) days after the receipt of funds,
an amount of the principal amount then outstanding on the Notes in the amount of
the proceeds received by Newco from a Permitted  Disposition  which,  during any
fiscal year when taken with all other Permitted  Dispositions,  exceeds $500,000
in the  aggregate,  less the  applicable  costs and taxes  payable in connection
therewith;  and (iii) within  fifteen  (15) days after the receipt of funds,  an
amount of the principal  amount then  outstanding  on the Notes in the amount of
the proceeds received by Newco from an Additional Financing, less the applicable
costs and taxes payable in connection therewith.

         Optional Prepayment

         Newco may prepay the Notes at its option at any time prior to September
30, 2001, at a prepayment price equal to the principal amount then  outstanding,
together with all accrued interest to the date of prepayment.


                                      -57-



         Events of Default; Annulment of Defaults

         If an Event of Default  (other than an Event of Default  resulting from
certain  specified  financial  difficulties  as defined in the  Preferred  Stock
Purchase and Noteholder Rights  Agreement) occurs and is continuing,  any holder
of the Notes may, by notice to the Company,  declare the entire unpaid principal
amount of the Notes,  all  interest  accrued  and unpaid  thereon  and all other
amounts payable  pursuant to the Preferred Stock Purchase and Noteholder  Rights
Agreement due and payable  immediately.  If an Event of Default  resulting  from
certain  specified  financial   difficulties  shall  occur,  the  entire  unpaid
principal  amount of the Notes,  all interest accrued and unpaid thereon and all
other amounts  payable  pursuant to the Preferred  Stock Purchase and Noteholder
Rights  Agreement  shall  become  due  and  payable   immediately   without  any
declaration  or  other  act on  the  part  of any  holders  of the  Notes.  Such
acceleration  and its  consequences may be annulled and rescinded by the holders
of  seventy-five  percent  (75%) or more in  principal  amount of all Notes then
outstanding,  upon the conditions set forth in the Preferred  Stock Purchase and
Noteholder  Rights  Agreement.  The term "Event of Default" means any one of the

or observe any term, covenant or agreement contained in the MICA Agreement which
remains  unremedied  for thirty (30) days; or (viii) the occurrence of any event
that has a material adverse effect on Newco.

Agreement,  for as long as the Preferred Shares or Notes are outstanding,  Newco

         MICA Agreement.

         Under the terms of the MICA  Agreement,  a copy of which is attached as
Exhibit  F to the  Asset  Purchase  Agreement,  Telebit  will  grant  to Newco a
worldwide,  non-exclusive,  non-transferable,  non-sublicensable  (except  under
certain  conditions  and  restrictions)  license to use the MICA  digital  modem
technology in object code only (as further  defined in the MICA  Agreement,  the
"Licensed  Technology").  The  scope of the  license  is  limited  to use of the
Licensed  Technology  only as  embedded  in products of Newco to which Newco has
added  substantial  value (the "Licensed  Products").  Under the MICA Agreement,
Newco  will not have  the  right to  market,  license,  sell or  distribute  the
Licensed  Technology as a stand-alone  product, as combined with any third party
product or as embedded  in any of Newco's  products to which Newco has not added
substantial  value.  In addition,  Newco will not be permitted to sublicense the
Licensed Technology (except to end users of Licensee Products pursuant to an end
user agreement  approved by Telebit in writing) unless: (i) it obtains the prior
written consent of Telebit, such consent at Telebit's sole discretion; (ii) such
sublicense is restricted  to use of the Licensed  Technology by the  sublicensee
only as embedded in such  sublicensee's  products to which such  sublicensee  or
Newco has added  substantial  value; and (iii) Newco pays Telebit a fee equal to
fifty percent (50%) of the sublicense  fees and royalties  received by Newco for
the  sublicense  of the  Licensed  Technology,  such  fees and  royalties  to be
credited  in  full  against  amounts  owed to  Telebit  pursuant  to the  Notes;
provided,  however,  that Newco will not be permitted to sublicense the Licensed
Technology to Bay Networks, Ascend, 3Com, U.S. Robotics, Shiva or Cascade or any
of their respective subsidiaries or affiliates.

         Telebit has agreed that it will not license the Licensed  Technology to
any third party for use in connection with wide area network  interface  ("WIC")
cards for the initial term of the MICA Agreement.

         The initial term of the MICA Agreement is three years commencing on the
date of consummation of the Asset Sale. During the initial term the license will
be royalty-free,  except in the case of permitted  sublicenses  discussed above.
The MICA  Agreement  shall  automatically  renew for an  additional  two  years,
subject to agreement by Telebit and Newco on a royalty  rate,  such royalty rate
to be  negotiated  in good faith and mutually  agreed upon by Telebit and Newco,
prior to the expiration of the initial term.

         Either  Telebit or Newco may  terminate  the MICA  Agreement  for cause
immediately  if  the  other  party:  (i)  ceases  to do  business  or  otherwise
terminates its business operations;  (ii) fails to secure, renew or maintain any
license,  registration,  permit,  authorization  or  approval  (each a "permit")
necessary  to the  conduct of its  business  or if any such permit is revoked or
suspended and not reinstated within thirty (30) days; (iii) materially  breaches
a material provision of the MICA Agreement,  which breach continues for a period
of  forty-five  (45) days after  written  notice  describing  such  breach  (and
immediately in the case of a breach of the confidentiality  obligation); or (iv)
seeks protection  under any bankruptcy or


                                      -60-


comparable  proceeding  or,  ninety  (90)  days  after  any such  proceeding  is
involuntarily commenced and not dismissed within such ninety-day period.

         Telebit  may  terminate  the MICA  Agreement  immediately  upon:  (i) a
default  by Newco  under the Note or (ii) upon any  merger or  consolidation  of
Newco with, or any sale,  pledge or other  disposition of  substantially  all of
Newco's  assets,  stock or business or of controlling  interest in Newco to, Bay
Networks,  Ascend,  3Com,  U.S.  Robotics,  Shiva  or  Cascade  or any of  their
respective subsidiaries or affiliates.

         ADSL Agreement.

         Under the ADSL  Agreement,  a copy of which is attached as Exhibit H to
the  Asset  Purchase  Agreement,  Telebit  will  grant  to  Newco  a  worldwide,
non-exclusive,    non-sublicensable   (except   under   certain   restrictions),
non-transferable license to research, develop,  manufacture,  have manufactured,
use, market, import, sell and distribute Newco products covered by a valid claim
of an issued  patent or a pending  claim of a pending  patent  application  with
respect to all  inventions  and  discoveries  claimed in the  patents and patent
applications  relating to asymmetric digital subscriber line ("ADSL") technology
(the "Licensed ADSL Patent  Rights").  Newco will not be permitted to sublicense
the Licensed ADSL Patent Rights unless: (i) it obtains the prior written consent
of  Telebit,  such  consent at  Telebit's  sole  discretion  and (ii) Newco pays
Telebit a fee equal to fifty percent (50%) of the sublicense  fees and royalties
received by Newco for the  sublicense of the Licensed ADSL Patent  Rights,  such
fees and  royalties  to be  credited  in full  against  amounts  owed to Telebit
pursuant to the Notes.

         The term of the ADSL Agreement commences on the date of consummation of
the Asset Sale and ends upon the expiration or termination of the last-to-expire
patent  under the  Licensed  ADSL  Patent  Rights.  During  the term of the ADSL
Agreement, the license granted is royalty-free,  except in the case of permitted
sublicenses discussed above.

         Either  Telebit or Newco may terminate the ADSL  Agreement for cause if
the other:  (i) ceases to do  business  or  otherwise  terminates  its  business
operations;  (ii) fails to secure, renew or maintain any license,  registration,
permit,  authorization or approval (each a "permit") necessary to the conduct of
its  business or if any such permit is revoked or suspended  and not  reinstated
within thirty (30) days; (iii) materially breaches any material provision of the
ADSL  Agreement,  which breach  continues for a period of thirty (30) days after
written  notice  describing  such  breach;  or (iv) seeks  protection  under any
bankruptcy  or  comparable  proceeding,  or  ninety  (90)  days  after  any such
proceeding is  involuntarily  commenced and not dismissed within such ninety-day
period.

         Telebit may terminate the ADSL  Agreement  upon: (i) a default by Newco
under the Note or (ii) any merger or  consolidation  of Newco with, or any sale,
pledge or other  disposition of  substantially  all of Newco's assets,  stock or
business or of  controlling  interest in Newco to, Bay Networks,  Ascend,  3Com,
U.S.  Robotics,  Shiva or Cascade  or any of their  respective  subsidiaries  or
affiliates.

         Analog Agreement.

         Under the Analog Agreement, a copy of which is attached as Exhibit G to
the  Asset  Purchase  Agreement,  Telebit  will  grant  to  Newco  a  worldwide,
non-exclusive,  sublicensable (subject to certain conditions),  non-transferable
license to research,  develop,  manufacture,  have  manufactured,  use,  market,
import, sell and distribute Newco products covered by a valid claim of an issued
patent or a pending claim of a pending  patent  application  with respect to all
inventions and  discoveries  claimed in the patents


                                      -61-


and patent  applications  of Telebit  specified  in the  Analog  Agreement  (the
"Licensed  Analog Patent  Rights").  Newco may  sublicense  the Licensed  Analog
Patent Rights provided that it gives written notice to Telebit.

         The  term  of  the  Analog   Agreement   commences  with  the  date  of
consummation  of the Asset Sale and ends upon the  expiration or  termination of
the  last-to-expire  patent under the Licensed Analog Patent Rights.  During the
term of the Analog Agreement, the license granted therein shall be royalty-free.

         Either Telebit or Newco may terminate the Analog Agreement for cause if
the other:  (i) ceases to do  business  or  otherwise  terminates  its  business
operations;  (ii) fails to secure, renew or maintain any license,  registration,
permit,  authorization or approval (each a "permit") necessary to the conduct of
its  business or if any such permit is revoked or suspended  and not  reinstated
within thirty (30) days; (iii) materially breaches any material provision of the
Analog Agreement,  which breach continues for a period of thirty (30) days after
written  notice  describing  such  breach;  or (iv) seeks  protection  under any
bankruptcy  or  comparable  proceeding  or,  ninety  (90)  days  after  any such
proceeding is  involuntarily  commenced and not dismissed within such ninety-day
period.

         Telebit may terminate the Analog Agreement upon: (i) a default by Newco
under the Note or (ii) any merger or  consolidation  of Newco with, or any sale,
pledge or other  disposition of  substantially  all of Newco's assets,  stock or
business or of  controlling  interest in Newco to, Bay Networks,  Ascend,  3Com,
U.S.  Robotics,  Shiva or Cascade  or any of their  respective  subsidiaries  or
affiliates.

         Employment Agreement of James D. Norrod.

         Under  the  terms  of  the  Employment   Agreement   (the   "Employment

Exhibit I to the Asset  Purchase  Agreement,  Mr.  Norrod  shall  serve as Chief
Executive  Officer  and  President  of Newco  and  shall  report to the Board of

INTERESTS OF CERTAIN PERSONS IN THE ASSET TRANSACTIONS

         In considering the  recommendation of the Telebit Board with respect to
the Asset  Transactions,  shareholders  of Telebit  should be aware that certain
officers  and  directors of Telebit  have  interests in the Asset  Transactions,
including  those  referred to below and those referred to under the caption "The
Merger--Interests  of Certain  Persons in the Merger," that  presented them with
potential conflicts of interests. The Telebit Board was aware of these potential
conflicts  and  considered  them along  with the other  matters  described  "The
Transactions--Reasons  for the  Transactions;  Recommendation  of the  Board  of
Directors."

         James D. Norrod,  President and Chief Executive Officer and a member of
the Telebit  Board,  is the  President,  sole director and sole  stockholder  of
Newco.  In  addition,  Newco has entered  into  employment  and  non-competition
agreements   with  Mr.   Norrod.   See   "Related   Agreements--Employment   and
Non-Competition Agreements."

         Telebit  has  agreed to pay up to $75,000  of the  reasonable  fees and
expenses  of  counsel  to  Newco  in  the  event  that  the  Asset  Sale  is not
consummated.

         The Asset  Purchase  Agreement  provides that, for a period of ten (10)
years from the closing date of the Asset Sale,  Newco shall  indemnify  and hold
harmless  Telebit,  its  affiliates,  and its  directors,  officers,  employees,
counsel or agents,  from and  against  all  losses,  claims,  demands,  actions,
proceedings,  damages,  liabilities or expenses (collectively  "Losses") arising
out of, resulting directly or indirectly from, or relating to: (i) the Purchased
Assets;  (ii)  the  Assumed  Liabilities;  (iii)  the  Asset  Sale,  or (iv) the
Business.  The Asset Purchase  Agreement  further provides that, for a period of
ten (10) years from the closing date of the Asset Sale,  Telebit shall indemnify
and hold harmless the directors, officers, employees, counsel or agents of Newco
from,  and against all Losses arising out of,  resulting  directly or indirectly
from or relating to the: (i) Excluded  Assets or (ii) the Excluded  Liabilities.
See "The Asset Purchase Agreement--Indemnification."

CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

         The following  discussion  summarizes  certain of the principal federal
income tax  consequences  of the Asset Sale to the  Company.  This  summary does
address the  foreign,  state or local tax  consequences  of the Asset  Sale.  In
addition,  this summary does not address all federal  income tax  considerations
that  may be  relevant  to the  Company,  including  but  not  limited  to,  the
alternative  minimum tax  consequences of the Asset Sale or the  availability of
the installment sales method of reporting gain attributable to the Asset Sale.

         As a result of the Asset Sale,  the Company  should  recognize  taxable
gain equal to the amount  paid by Newco  (including  liabilities  of the Company
assumed) less the Company's  adjusted tax basis in the assets disposed of in the
Asset Sale.  The amount of gain subject to federal  income tax may be reduced by
the Company's net operating losses.

ACCOUNTING TREATMENT

         The Asset  Sale is  expected  to be  accounted  for under the  purchase
method of  accounting,  with Newco as the acquiring  party,  in accordance  with
generally  accepted  accounting   principles.   Under  the  purchase  method  of
accounting,  the  purchase  price paid for  certain  assets and  liabilities  of
Telebit will be


                                      -63-


allocated to the respective  assets acquired and liabilities  assumed based upon
their  estimated  fair values,  with any excess of the  purchase  price over the
estimated fair value of net assets acquired being recorded as goodwill.



                                      -64-



                          OPINIONS OF FINANCIAL ADVISOR


                  In  connection  with the meeting of the Special  Committee  on
July 20, 1996,  Allen  delivered  its oral opinions  (subsequently  confirmed in
writing)  to the effect  that,  as of such  date:  (i) the  consideration  to be
received by holders of Telebit  Common Stock  pursuant to the Merger was fair to
such holders  from a financial  point of view and (ii) the  consideration  to be
received  by  Telebit  pursuant  to the Asset  Sale was fair to  Telebit  from a
financial point of view. Allen has  subsequently  delivered its written opinions
dated  ___________  ___, 1996,  reaffirming its July 20, 1996 opinions as of the
date of this Proxy Statement.

                  The full text of the written opinions of Allen,  dated [insert
date of bring-down  opinions] is set forth as Appendix D to this Proxy Statement
and describes the assumptions made,  matters considered and limits on the review
undertaken.  Telebit  shareholders  are  urged  to read  the  opinions  in their
entirety.  Allen's opinions are directed to the fairness, from a financial point
of view, of the  consideration  which the holders of Telebit  Common Stock would
receive  in the Merger and  Telebit  would  receive in the Asset Sale and do not
constitute a recommendation  of the proposed  Transactions over other courses of
action that may be available to Telebit or  constitute a  recommendation  to any
holder of Telebit  Common  Stock  concerning  how such  holder  should vote with
respect to: (i) the  proposal to approve and adopt the Merger  Agreement  and to
approve  consummation  of the Merger and (ii) the  proposal to approve and adopt
the Asset Purchase Agreement and to approve  consummation of the Asset Sale. The
scope of Allen's  engagement in connection  with the proposed  Transactions  was
limited to the preparation and rendering of its opinions. In connection with the
preparation  of its  opinions,  Allen was not  authorized  by the Company or the
Telebit Board to solicit third party indications of interest for the acquisition
of all or any part of the  Company.  This  summary of the  opinions of Allen set
forth in this Proxy  Statement  is qualified in its entirety by reference to the
full text of such opinions.

                  In arriving at its opinions, Allen: (i) reviewed the terms and
conditions of the proposed  Transactions,  including the draft Merger  Agreement
between  Telebit and Cisco,  together  with drafts of the  agreements  ancillary
thereto,  and the draft Asset  Purchase  Agreement  between  Newco and  Telebit,
together with drafts of the agreements  ancillary thereto,  (none of which prior
to the delivery of Allen's  opinions  had been  executed by the  parties);  (ii)
analyzed  publicly  available  historical  business  and  financial  information
relating  to  Telebit  and  Cisco,  as  presented  in  documents  filed with the
Commission;  (iii) reviewed  certain business plans,  budgetary,  and other data
provided  to  Allen  by  Telebit  relating  to  its  business;   (iv)  conducted
discussions  with  certain  members of the  senior  management  of Telebit  with
respect to the financial condition, business,  operations,  strategic objectives
and  prospects of Telebit,  as well as industry  trends  prevailing in Telebit's
business; (v) reviewed and analyzed public information,  including certain stock
market data and financial  information  relating to selected public companies in
lines of business which Allen  believed to be comparable to Telebit's  business;
(vi)  reviewed  the  trading  history of Telebit  Common  Stock,  including  its
performance  in  comparison  to market  indices  and to  selected  companies  in
comparable   businesses;   (vii)  reviewed  public   financial  and  transaction
information  relating to business  combinations Allen deemed to be comparable to
the proposed Transactions; (viii) considered premiums paid in transactions Allen
deemed comparable to the Merger;  (ix) analyzed discounted cash flows of each of
Telebit  and the portion of Telebit  that is the subject of the Asset Sale;  and
(x) conducted such other financial  analyses and  investigations as Allen deemed
necessary or appropriate for the purposes of its opinions.

                  In connection with its review, Allen assumed and relied on the
accuracy and  completeness of the information it reviewed for the purpose of its
opinions and did not assume any 


                                      -65-


responsibility  for  independent  verification  of such  information or make any
independent  evaluation  or appraisal of the assets of Telebit.  With respect to
Telebit's business plans,  Allen assumed that they had been reasonably  prepared
on bases reflecting the best currently  available estimates and judgments of the
management of Telebit and Newco,  and Allen expressed no opinion with respect to
such  business  plans or the  assumptions  on which  they  were  based.  Allen's
opinions  were  necessarily  based upon  business,  market,  economic  and other
conditions  as they  existed on, and could be  evaluated  as of, the date of its
opinions.

                  The following is a summary of the  presentation  made by Allen
to the Special  Committee in  connection  with the rendering of Allen's July 20,
1996 fairness opinions:

                  (i)  Transaction  Summary.  Prior to  delivering  its  written
opinions to the Special Committee,  Allen reviewed certain  information with the
Special Committee  relating to Telebit and Cisco,  including the financial terms
of the Merger and the Asset Sale, the consideration to be received by holders of
Telebit Common Stock and the financial analyses summarized below.

                  Allen  noted  that the  Merger  Agreement  provides  that each
outstanding  share of Telebit  Common  Stock will be exchanged in the Merger for
cash in the  amount  of  $13.35.  Allen  noted  that  the  Merger  Consideration
represented a premium of 21.4% over the closing price of Telebit Common Stock as
of July 18, 1996  ($11.00),  prior to the public  announcement  of the  proposed
Transactions.  In  addition,  Allen  calculated  that,  based  upon  the  Merger
Consideration,  the equity value (the value of all equity securities) of Telebit
was $197.7  million and the  transaction  or enterprise  value (the value of all
equity  securities  plus long-term debt less cash) of Telebit as a result of the
Merger was $189.0 million.

                  (ii)  Overview  of  Telebit.  Allen  presented  an overview of
Telebit,  which  included an overview of  Telebit's  established  core modem and
router  business  and  general  internetworking   industry  trends.  Allen  also
presented an overview of the overall  remote access server  ("RAS") market which
showed a 21.0% decline in Telebit's end-user sales from $29.2 million in 1994 to
$23.0  million in 1995 and a resulting  decline in  Telebit's  market  share and
market  ranking  from  11.4%  and  4th,  respectively,  in 1994 to 3.2% and 9th,
respectively, in 1995.

                  Allen reviewed Telebit's  historical operating results for the
three  fiscal  years ended  December  31, 1993  through  1995 and its  estimated
operating  results for the five fiscal  years  ending  December 31, 1996 through
2000,  noting  particularly  Telebit's  earnings per share ("EPS") for the three
fiscal  years ended  December  31,  1993  through  1995 of ($0.83),  ($0.12) and
($1.04), respectively, compared to estimated EPS of ($0.02), $0.68, $0.97, $0.52
and $0.45,  respectively,  for the five fiscal  years  ending  December 31, 1996
through  2000. In addition,  Allen noted  Telebit's EPS for the six months ended
June 30, 1996 of ($0.10),  as compared to  Telebit's  EPS for the  corresponding
prior year period of ($0.54) and for the last twelve  months  ("LTM") ended June
30, 1996 of ($0.46).  Allen also reviewed Telebit's  historical balance sheet at
June 30, 1996 and its operating results for the LTM ended on such date.

                  Allen reviewed stock price and trading volume data for Telebit
Common Stock,  comparing  Telebit's general trading patterns to those of the S&P
500  Index  and an  index of  internetworking  companies  deemed  by Allen to be
engaged  in lines  of  business  similar  to the  business  of  Telebit  (Ascend
Communications,  Inc., Bay Networks Inc., Cisco Systems, Inc., 3Com Corporation,
Gandalf Technologies,  Inc., Microcom, Inc., Shiva Corporation and U.S. Robotics
Corporation;  referred to herein as the  "Comparable  Companies  Group").  Allen
noted that although  Telebit's general trading patterns have out performed those
of the S&P 500  Index  in  recent  months,  they  performed  below  those


                                      -66-



of the Comparable  Companies Group.  Telebit's trading patterns,  as compared to
those of the Comparable  Companies  Group,  were consistent with Telebit's lower
projected growth rates over the periods examined. Allen commented that Telebit's
relatively small market  capitalization may have limited the interest in Telebit
Common Stock by some large institutional investors. Allen also compared selected
multiples  derived  from the recent  price of Telebit  Common Stock to multiples
derived  from  recent  trading  price of the  Comparable  Companies  Group.  The
multiples compared included enterprise value to LTM revenues (which was 3.0x for
Telebit  compared  to a range of 0.7x to 13.9x  and an  average  of 5.6x for the
Comparable  Companies Group,  equity value to estimated 1997 earnings (which was
45.8x for  Telebit  compared to a range of 6.3x to 42.3x and an average of 20.4x
for the  Comparable  Companies  Group) and equity value to book value (which was
9.8x for  Telebit  compared  to a range of 1.3x to 17.4x and an average of 10.2x
for the Comparable Companies Group).  However, other market multiple comparisons
between  Telebit and the Comparable  Companies  Group were not meaningful due to
Telebit's negative operating results for the period examined.

                  (iii) Merger  Overview and  Analysis.  Allen also analyzed the
total  enterprise  value of  Telebit  as of July 18,  1996  prior to the  public
announcement of the proposed Transactions to the total enterprise value based on
the Merger Consideration. This analysis indicated an enterprise value of Telebit
of $158.8  million  without  giving effect to the Merger,  as compared to $189.0
million based on the Merger Consideration.  Allen also compared the total equity
value of  Telebit as of July 18,  1996 to the total  equity  value  based on the
Merger  Consideration.  This  analysis  indicated  an equity value of Telebit of
$161.8  million  without  giving  effect to the  Merger,  as  compared to $197.7
million based on the Merger Consideration.

                  Allen   performed  a  discounted   cash  flow  analysis  using
Telebit's business plan. Allen calculated Telebit's net present equity value and
net present per share value for the years 1996 through 2000 using discount rates
ranging from 10.0% to 20.0%. Allen calculated Telebit's net present equity value
and net present value per share value based upon  terminal  multiples of 8.0x to
12.0x Telebit's earnings before interest,  taxes,  depreciation and amortization
("EBITDA").  Allen noted that  Telebit's  total equity  value of $197.7  million
based  on the  Merger  Consideration  and  the per  share  value  of the  Merger
Consideration  exceeded  the  discounted  cash flow equity  values and per share
values derived from this discounted cash flow analysis.

                  Allen  compared  the  premium  of 21.4%  payable to holders of
Telebit Common Stock as of July 18, 1996 prior to the public announcement of the
proposed Transactions to premiums paid in (i) selected  internetworking industry
transactions  occurring  between January 1, 1994 and July 19, 1996  ("Comparable
Industry  Transactions")  and (ii) in selected all-cash  transactions  occurring
between January 1, 1994 and July 19, 1996 with  transaction  values between $100
million and $500 million ("Selected  All-Cash  Transactions").  Allen noted that
the premiums, as compared to the trading price on the day prior to announcement,
in the Comparable Industry  Transactions  averaged 19.8% and ranged from (10.6%)
to 62.3% and in the Selected  All-Cash  Transactions  averaged  41.0% and ranged
from (17.1%) to 186.2%.  Allen also analyzed  these premium ranges as of one and
four weeks  prior to the  public  announcement  of the Merger and such  selected
transactions.   These   analyses   indicated   that  the  Merger   Consideration
approximated the average premiums paid in Comparable  Industry  Transactions and
is below the  average  premiums in Selected  All-Cash  Transactions.  Allen also
noted that based on the 90-day  rolling  average price of Telebit  Common Stock,
the Merger Consideration represents a premium of 52.6%.

                  Allen also analyzed the  enterprise  value  represented by the
consideration  to be received by the Telebit  shareholders  in the Merger  based
upon the Merger  Consideration  as a multiple of LTM


                                      -67-



sales  (3.7x) and  compared  such  multiple  to  multiples  of LTM sales for (i)
Comparable  Industry  Transactions  which  ranged from 0.5x to 6.6x and averaged
3.5x and (ii) Selected  All-Cash  Transactions  which ranged from 0.2x and 10.0x
and averaged  2.6x.  Allen also  compared the equity  value  represented  by the
consideration  to be  received by the  Telebit  shareholders  in the Merger as a
multiple of LTM book value and compared  such  multiple to the multiples for (i)
Comparable  Industry  Transactions  which ranged from 3.0x to 13.3x and averaged
6.7x and (ii) Selected  All-Cash  Transactions  which ranged from 0.5x and 11.4x
and  averaged  3.0x.  These  analyses  indicated  that the Merger  Consideration
results in valuation  multiples which are generally higher than the multiples in
Comparable Industry Transactions and in Selected All-Cash Transactions.

                  (iv) Asset Sale  Overview  and  Analysis.  Allen  presented an
overview of Telebit's Legacy Business,  which, following the Asset Sale, will be
operated by Newco. Allen noted that the value ascribed to the legacy business in
the  Asset  Sale was  $35.0  million  comprised  of the  $31.5  million  Secured
Subordinated  Notes due 2001 and $3.5  million of Class A  Redeemable  Preferred
Stock to be issued in connection with the Asset Sale.

                  Allen  performed a discounted  cash flow analysis of Telebit's
Legacy  Business  using  Telebit's  business plan.  Allen  calculated the legacy
business'  net present  asset value using  discount  rates ranging from 15.0% to
25.0% and terminal multiples of 8.0x to 12.0x EBITDA. Allen noted that the Asset
Sale value exceeded the mid-range discounted cash flow asset values derived from
this analysis.

                  Allen also derived a historical  revenue multiple of 0.79x for
Telebit's Legacy Business by calculating  Telebit's  enterprise value based upon
the average  Telebit  Common Stock price between June 30, 1995 and September 30,
1995 (prior to the time the securities markets had likely taken into account the
full value of Telebit's MICA business or the future prospects thereof) comparing
such  enterprise  value to Telebit's 1995  revenues.  Allen applied such revenue
multiple of 0.79x to Telebit's  estimated 1996 revenues from its legacy business
($41.2 million),  which procedure yielded an implied current market valuation of
Telebit's  legacy  business  of $32.7  million.  Allen  noted  that  Asset  Sale
valuation exceeded such implied current market valuation.

                  No company used in the comparable company analyses  summarized
above is identical to Telebit or its Legacy Business, and no transaction used in
the  comparable  transactions  analysis  summarized  above is  identical  to the
proposed Transactions. Accordingly, any such analysis of the consideration to be
received by (i) the holders of Telebit  Common Stock  pursuant to the Merger and
(ii) Telebit  pursuant to the Asset Sale  involves  complex  considerations  and
judgments  concerning  differences  in the  potential  financial  and  operating
characteristics  of the comparable  companies and Transactions and other factors
in relation to the trading and acquisition values of the comparable companies.

                  The  preparation of a fairness  opinions is not susceptible to
partial  analysis or summary  description.  Allen believes that its analyses and
the  summary set forth above must be  considered  as a whole and that  selecting
portions of its analyses and the factors  considered by it, without  considering
all analyses  and factors,  could  create an  incomplete  view of the  processes
underlying the analysis set forth in its opinions.  Allen has not indicated that
any of the  analyses  which it  performed  had a greater  significance  than any
other.

                  In determining  the  appropriate  analyses to conduct and when
performing  those  analyses,  Allen made  numerous  assumptions  with respect to
industry  performance,   general  business,   financial,   market  and  economic
conditions and other matters, many of which are beyond the control of Telebit or


                                      -68-



Cisco.  The analyses  which Allen  performed are not  necessarily  indicative of
actual values or actual future results,  which may be significantly more or less
favorable than suggested by such analyses. Such analyses were prepared solely as
part of Allen's analysis of the fairness, from a financial point of view, of the
consideration  which the holders of Telebit Common Stock would receive  pursuant
to the Merger and which Telebit would  receive  pursuant to the Asset Sale.  The
analyses  do not  purport to be  appraisals  or to reflect the prices at which a
company or the assets might  actually be sold in the  aggregate or separately or
the prices at which any  securities may trade at the present time or at any time
in the future.

         Allen  is a  nationally  recognized  investment  banking  firm  that is
continually  engaged in the  valuation of  businesses  and their  securities  in
connection with mergers and acquisitions, negotiated underwritings,  competitive
bids,  secondary  distributions  of  listed  and  unlisted  securities,  private
placements  and  valuations for estate,  corporate and other  purposes.  Telebit
retained Allen based on such  qualifications,  as well as its  familiarity  with
Telebit. In addition, as a part of its investment banking and securities trading
business,  Allen may hold  positions in and trade in the  securities  of Telebit
from time to time.

                  Telebit entered into a letter  agreement with Allen dated July
18, 1996 (the "Engagement  Letter"),  pursuant to which Allen agreed to evaluate
the fairness from a financial point of view of the  consideration to be received
by holders of Telebit  Common  Stock  pursuant to the Merger and to evaluate the
fairness from a financial point of view of the  consideration  to be received by
Telebit pursuant to the Asset Sale. Pursuant to such Engagement Letter,  Telebit
agreed,  among  other  things,  to pay  Allen  a fee of  $275,000  payable  upon
submission  of  Allen's  fairness  opinions  to the  Telebit  Board  or any duly
constituted  committee  thereof.  Whether or not the  proposed  Transactions  is
consummated,  Telebit  has  agreed,  pursuant  to  such  Engagement  Letter,  to
reimburse Allen for all its reasonable  out-of-pocket  expenses and to indemnify
Allen  against   certain   liabilities  and  expenses  in  connection  with  its
engagement.

                        RIGHTS OF DISSENTING SHAREHOLDERS

         If the  proposed  Transactions  are  approved by the  required  vote of
Telebit shareholders and is not abandoned or terminated,  each holder of Telebit
Common Stock who voted against: (i) the proposal to approve and adopt the Merger
Agreement and approve consummation of the Merger or (ii) the proposal to approve
and adopt the Asset  Purchase  Agreement and approve  consummation  of the Asset
Sale or (iii) both  proposals  may, by complying with Sections 1300 through 1312
of the California  General  Corporation Law  ("California  Law"), be entitled to
dissenters' rights as described therein, provided that: (i) such holder's shares
of Telebit  Common  Stock are  subject to  restriction  on  transfer  imposed by
Telebit or by law or  regulation  or (ii)  demands for payment  pursuant to such
dissenters'  rights  are filed  with  respect  to 5% or more of the  outstanding
shares of Telebit Common Stock on or before the date of the Special Meeting. The
record  holders of the shares of Telebit Common Stock which are eligible to, and
do, exercise their dissenters' rights with respect to the Merger, the Asset Sale
or both are referred to herein as "Dissenting Shareholders," and the shares with
respect to which they may exercise  dissenters' rights are referred to herein as
"Dissenting  Shares."  If a Telebit  shareholder  has a  beneficial  interest in
shares of  Telebit  Common  Stock that are held of record in the name of another
person,  such as a broker or nominee,  and such  shareholder  desires to perfect
whatever   dissenters'  rights  such  beneficial   shareholder  may  have,  such
beneficial shareholder must act promptly to cause the holder of record to timely
and properly follow the steps summarized below.

         The following  discussion is not a complete statement of the California
Law  relating  to  dissenters'  rights,  and is  qualified  in its  entirety  by
reference to Sections 1300 through 1312 of the  California  Law attached to this
Proxy  Statement  as  Appendix  E and  incorporated  herein by  reference.  This
discussion  and  Section  1300  through  1312 of the  California  Law  should be
reviewed   carefully  by  any  shareholder  who  wishes  to  exercise  statutory
dissenters'  rights or wishes to preserve the right to do so,  since  failure to
comply with the required procedures will result in the loss of such rights.

         Shares of Telebit  Common  Stock  must  satisfy  each of the  following
requirements to qualify as Dissenting  Shares under the California Law: (i) such
shares of Telebit Common Stock must have been outstanding on the Record Date for
the  determination  of the holders of Telebit  Common Stock entitled to voted at
the Special  Meeting;  (ii) such shares of Telebit  Common  Stock must have been
voted against (a) the proposal to approve the Merger  Agreement and consummation
of the Merger,  or (b) the proposal to approve the Asset Purchase  Agreement and
consummation of the Asset Sale or (c) both proposals;  (iii) the holders of such
shares  of  Telebit  Common  Stock  must  make a  written  demand  that  Telebit
repurchase  shares of Telebit  Common Stock at fair market value and such demand
must be received by either Telebit or Telebit's transfer agent no later than the
date of the  Special  Meeting;  and (iv) the  holder of such  shares of  Telebit
Common Stock must submit  certificates  for endorsement (as described  below). A
vote by proxy or in person  against  (i) the  proposal  to approve and adopt the
Merger Agreement and approve consummation of the Merger; or (ii) the proposal to
approve and adopt the Asset Purchase  Agreement and approve  consummation of the
Asset  Sale;  or (iii) both  proposals  does not in and of itself  constitute  a
demand for appraisal  under the California  Law. In addition,  in order for such
shares of Telebit Common Stock to qualify as Dissenting  Shares, (i) demands for
payment  must have been  filed  with  respect  to 5% or more of the  outstanding
shares of Telebit  Common  Stock on or before the  Special  Meeting or (ii) such
shares of Telebit  Common  Stock must be subject to a  restriction  on  transfer
imposed by Telebit or by any law or regulation.

         Pursuant  to  Sections  1300  through  1312  of  the  California   Law,
Dissenting  Shareholders  may require  Telebit to  repurchase  their  Dissenting
Shares at a price equal to the fair market value of such shares determined as of
the day before the first announcement of the terms of the proposed Transactions,


                                      -70-


excluding  any  appreciation  or  depreciation  in  consequence  of the proposed
Transactions,  but adjusted for any stock  split,  reverse  stock split or stock
dividend which becomes effective thereafter.  On July 19, 1996 the last full day
of  trading  prior  to  the  public   announcement   relating  to  the  proposed
Transactions, the closing price per share of Telebit Common Stock was $10.88.

         The demand of a  Dissenting  Shareholder  must be made in writing  upon
Telebit no later than the date of the Special  Meeting and is required by law to
state the number and class of Dissenting Shares held of record by the Dissenting
Shareholder which the Dissenting  Shareholder demands that Telebit purchase, and
to contain a statement of what the Dissenting  Shareholder claims to be the fair
market  value  of  the  Dissenting  Shares  as  of  the  day  before  the  first
announcement of the proposed Transactions. The statement of fair market value in
such demand by the Dissenting Shareholder constitutes an offer by the Dissenting
Shareholder to sell the Dissenting Shares at such price.

         If there are any Dissenting Shareholders, then within 10 days following
approval  of the  proposed  Transactions  by  Telebit  Shareholders,  Telebit is
required to mail to each holder of Dissenting Shares a notice of the approval of
the proposed  Transactions,  a statement of the price  determined  by Telebit to
represent the fair market value of Dissenting  Shares (which shall constitute an
offer by Telebit to purchase such Dissenting Shares at such stated price), and a
description of the procedures to be followed for such  shareholders  to exercise
their rights as Dissenting Shareholders.

         Within  thirty  (30) days  after  the date on which  the  notice of the
approval of the proposed  Transactions by the outstanding shares was mailed to a
Dissenting Shareholder, that shareholder who wishes to be paid the full value of
his or her  Dissenting  Shares  must  submit to  Telebit or its  transfer  agent
certificates representing any Dissenting Shares which the Dissenting Shareholder
demands Telebit  purchase,  so that such Dissenting Shares may either be stamped
or  endorsed  with the  statement  that the  shares  are  Dissenting  Shares  or
exchanged for certificates of appropriate denomination so stamped or endorsed.

         If,  upon a  Dissenting  Shareholder's  surrender  of the  certificates
representing that Dissenting  Shareholder's  Dissenting Shares,  Telebit and the
Dissenting  Shareholder  agree that such shares are Dissenting  Shares and agree
upon the price to be paid for such shares,  then the agreed price is required by
law to be paid to the Dissenting  Shareholder  within the later of 30 days after
the  date of  such  agreement  or  thirty  (30)  days  after  any  statutory  or
contractual  conditions  to  consummation  of the  Merger or the Asset  Sale are
satisfied, unless provided otherwise by agreement.

         If Telebit and a  Dissenting  Shareholder  disagree as to whether  such
Dissenting   Shareholder's   proposed  Dissenting  Shares  are  entitled  to  be
classified as  Dissenting  Shares or as to the fair market value of such shares,
then such Dissenting  Shareholder has the right to bring an action in California
Superior Court,  within six (6) months after the date on which the notice of the
approval of the proposed  Transactions by Telebit Shareholders was mailed to the
Dissenting Shareholder,  to resolve such dispute. In such action, the court will
determine  whether the shares of Telebit  Common  Stock held by such  Dissenting
Shareholder  are  Dissenting  Shares,  the fair market value of such shares,  or
both.  The  California  Law  provides,  among other  things,  that a  Dissenting
Shareholder  may not  withdraw a demand for payment of the fair market  value of
Dissenting Shares unless Telebit consents to such request for withdrawal.

                               REGULATORY MATTERS

         Under the HSR Act, and the rules promulgated thereunder by the FTC, the
Merger may not be consummated  until  notifications  have been given and certain
information  has  been  furnished  to the  FTC and the  Antitrust  Division  and
specified  waiting period  requirements  have been satisfied.  Each of Cisco and
Telebit originally filed their respective Notification and Report Forms required
under the HSR Act with the FTC and the Antitrust  Division on August 5, 1996 and
applicable waiting period under the HSR Act expired/was waived on __________ __,
1996.  At any time  before or after  consummation  of the Merger,  the FTC,  the
Antitrust  Division,  the state  attorneys  general or others  could take action
under the antitrust laws with respect to the Merger, including seeking to enjoin
consummation of the Merger or seeking divestiture of substantial assets of Cisco
or Telebit.

         Based on information  available to them, Cisco and Telebit believe that
the Merger will not violate federal or state antitrust laws. However,  there can
be no  assurance  that a challenge  to  consummation  of the Merger on antitrust
grounds  will not be made or that,  if such a  challenge  were  made,  Cisco and
Telebit  would  prevail or would not be required to accept  certain  conditions,
possibly including certain divestitures or hold-separate arrangements,  in order
to consummate the Merger.

                       CERTAIN INFORMATION REGARDING CISCO

         Cisco develops,  manufactures,  markets and supports  high-performance,
multiprotocol  internetworking  systems that link geographically  dispersed LANs
and WANs to form a single information  infrastructure.  Cisco products include a
wide range of routers, LAN and ATM switches,  dial-up access servers and network
management software solutions.  The common thread running through these products
is the Cisco IOS software, which today provides the native intelligence for more
than 450,000  installed  Cisco units and is an integral  part of the products of
more than two dozen global partners.

         The  Cisco  IOS  software  is  a  sophisticated   suite  of  networking
capabilities that provides network  connectivity,  security and interoperability
for all of today's  standard data  protocols,  media access methods and products
from leading information service vendors.  This software resides at the heart of
Cisco's internetworking  products and within the hardware of more than two dozen
vendor  partners  including  Alcatel,   Cabletron  Systems,   Compaq  Computers,
LanOptics, NEC, Northern Telecom and Sun Microsystems.  Cisco's modular hardware
and software  architecture allows products to be configured in a wide variety of
ways to suit customers' specific needs.

         Cisco  expanded the Cisco IOS feature set by addressing new markets and
technologies.  These  include  a range of  remote  access  products,  as well as
switching  products.  In 1994,  Cisco  introduced the CiscoFusion  architecture,
which blends the capabilities of today's routed  internetworks with the emerging
technologies of ATM, LAN workgroup switches and virtual LANs.

         Cisco sells its products in  approximately  seventy five (75) countries
through a  combination  of direct sales,  distributors,  and direct and indirect
resellers.  Cisco's worldwide OEM customers and resellers include Alcatel, AT&T,
British  Telecom,   Cabletron  Systems,  Digital  Equipment  Company,  Ericsson,
Hewlett-Packard,  MCI, NEC Company,  Olivetti,  Siemens,  Sprint,  Unisys and US
West. Cisco has established  technology  partnerships with a number of companies
to address  specialized  segments of the  internetworking  marketplace,  and has
partnered with leading WAN  technology  and service  providers to offer flexible
options to  customers.  Cisco offers  customer  service and support  through its
technical  assistance  centers in  California,  North  Carolina,  Australia  and
Belgium,  and provides on-site hardware maintenance on a worldwide basis through
IBM, AT&T and Hewlett-Packard.

                       CERTAIN INFORMATION REGARDING NEWCO


         Newco is a Delaware corporation recently organized by, James D. Norrod,
President and Chief Executive  Officer of Telebit.  Mr. Norrod is the President,
sole director and sole stockholder of Newco. Newco was incorporated for the sole
purpose of  effecting  the Asset  Sale.  It has no  material  assets and has not
engaged in any activities except in connection with the proposed Asset Sale.

                      CERTAIN INFORMATION REGARDING TELEBIT


         Telebit designs, manufactures,  sells, markets and supports a family of
high-performance remote network access products. These products enable customers
to  build:  (i)  dial-up  LAN   inter-networks   that  provide  remote  offices,
telecommuters  and mobile  computer  users  access to corporate  networks;  (ii)
remote LAN access networks that provide access to the Internet and (iii) mission
critical  WAN access  facilities  that provide LAN or host access over the PSTN.
The Company's  products  consist  primarily of the  NetBlazer  family of dial-up
access routers and modem  products  consisting  primarily of high-speed  dial-up
modems and modem network  management  systems.  The Company markets its products
worldwide through  distributors,  VARs and service  providers.  The Company also
sells its modem products to certain OEMs.

         The Company's  strategy is to capitalize on several  significant trends
in the data communications  industry,  including: (i) the growing demand for LAN
to LAN  connectivity  to provide  affordable  links between  business  partners,
branch  offices  and  corporate  LANs over the WAN;  (ii) the need for  seamless
internetworking  and   interoperability  of  disparate  computers  and  computer
networks; (iii) the growing demand for client to LAN connectivity resulting from
the growth in sales of laptop and notebook size  computers to mobile workers and
telecommuters;  (iv) the continuing  evolution of high-speed  analog and digital
technology  enabling  dial-up  networking  solutions;   and  (v)  the  need  for
high-density, lower cost, central site remote network access solutions.

         The  requirements for remote access continue to grow as a result of the
need for remote  offices and workers to gain access to corporate  resources  and
the proliferation of the internet.  At the central site,  larger  organizations,
such as  company  headquarters  or an online  service  provider,  that have made
extensive  commitment to primary rate ISDN (T1/E1) for  telecommunications  find
themselves needing to support both digital ISDN communications as well as analog
data  transmissions  from their  remote  users.  The  complexity  and expense of
supporting both forms of communications has spurred a demand for new products to
handle this  communication  seamlessly.  This emerging  market has presented the
opportunity to reduce cost and complexity by aggregating the  analog-originating
traffic   as  well  as  basic  rate  ISDN  onto  a  single   primary-rate   ISDN
communications line.

         Telebit  identified this market opportunity during the third quarter of
1995, and in response to this market need, undertook the development of its MICA
Technology.  The MICA  Technology is being developed to allow  organizations  to
eliminate the need for multiple analog lines and corresponding analog modems and
replace this  functionality  with a  high-density  ISA card based  digital modem
solution  using a single  common  high-speed  digital  line with the  ability to
dynamically  configure  channels to handle both  digital  and  digitized  analog
transmissions.

         The Company's  strategy for MICA includes:  (i) integration of the MICA
Technology with the Company's NetBlazer family of dialup router/server products;
(ii)  integration  of the  MICA  Technology  into  standard  industry  operating
systems,  such as Windows NT and Novell NetWare; and (iii) licensing or entering
into OEM relationships with third-parties for high-density,  lower cost, central
site remote network  access  solutions.  The initial  shipments of the Company's
MICA-based products are scheduled for the third quarter of 1996.

                            CERTAIN LEGAL PROCEEDINGS

         On August 2,  1996,  a  complaint  was filed in the  Middlesex  County,
Massachusetts,  Superior  Court,  entitled  Dr.  Herb  Golden v.  James P. (sic)
Norrod,  Michael K. Ballard,  C. Richard  Kramblich (sic),  Scott J. Loftesness,
Cisco Systems,  Inc. and Telebit  Corporation  (Civil Action No.  96-4537).  The
lawsuit relates to the proposed transactions.

         The suit alleges,  among other  things,  that the Merger and Asset Sale
will  not be in the best  interest  of  Telebit's  shareholders.  The suit  also
alleges that the consideration  being paid in connection with the Asset Sale and
the proposed  Merger  Consideration  of $13.35 per share are below market value.
The  suit  asks  the  court to  enjoin  the  closing  of the  transactions,  or,
alternatively, to award unspecified damages from the defendants in the event the
transactions are consummated.

         Cisco and Telebit  believe that the suit is without merit and intend to
defend it vigorously.

         NOW,  THEREFORE,  in consideration of the covenants and representations

which is hereby acknowledged, the parties agree as follows:



                                    ARTICLE I

                                   THE MERGER
                                   ----------

         1.1 The Merger.  Effective Time (as defined in Section 1.2) and subject
to and upon the terms and conditions of this Agreement,  the Agreement of Merger
attached  hereto as Exhibit A (the  "Agreement  of Merger")  and the  applicable
provisions of the California  Corporations Code ("California  Law"),  Merger Sub
shall be merged with and into Target, the separate corporate existence of Merger
Sub shall cease and Target shall continue as the surviving  corporation.  Target
as the surviving  corporation after the Merger is hereinafter sometimes referred
to as the "Surviving Corporation."

         1.2  Closing;   Effective   Time.  The  closing  of  the   transactions
contemplated hereby (the "Closing") shall take place as soon as practicable (and
in any event within two business days) after the  satisfaction or waiver of each
of the  conditions  set forth in  Article VI hereof or at such other time as the
parties hereto agree (the "Closing  Date").  The Closing shall take place at the
offices of Brobeck,  Phleger & Harrison LLP, Palo Alto,  California,  or at such
other  location as the parties  hereto agree.  On the Closing Date,  the parties
hereto  shall  cause the Merger to be  consummated  by filing the  Agreement  of
Merger with the  Secretary of State of the State of  California,  in  accordance
with the relevant  provisions of  California  Law (the time of such filing being
the "Effective Time").

         1.3 Effect of the  Merger.  At the  Effective  Time,  the effect of the
Merger shall be as provided in this  Agreement,  the Agreement of Merger and the
applicable  provisions of California Law. Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time, all the property, rights,
privileges,  powers  and  franchises  of Target and Merger Sub shall vest in the
Surviving  Corporation,  and all  debts,  liabilities  and  duties of Target and
Merger  Sub shall  become  the debts,  liabilities  and duties of the  Surviving
Corporation.

         1.4 Articles of Incorporation; Bylaws.

                  a. At the Effective  Time,  the Articles of  Incorporation  of
Merger Sub, as in effect  immediately  prior to the Effective Time, shall be the
Articles of Incorporation of the Surviving  Corporation until thereafter amended
as provided by  California  Law and such  Articles of  Incorporation;  provided,
however,  that  Article I of the  Articles  of  Incorporation  of the  Surviving
Corporation  shall be  amended  to change the  corporate  name of the  Surviving
Corporation to a name other than Target's present  corporate name or a corporate
name closely resembling Target's present corporate name.

                  b. The Bylaws of Merger Sub, as in effect immediately prior to
the  Effective  Time,  shall be the Bylaws of the  Surviving  Corporation  until
thereafter amended.

         1.5 Directors and Officers. At the Effective Time, the directors of the
Merger Sub shall be the initial  directors  of the  Surviving  Corporation,  who
shall  survive  until  their  successors  are  duly  elected  or  appointed  and
qualified,  and the officers of Merger Sub shall be the initial


                                      -2-


officers of the Surviving Corporation,  who shall survive until their respective
successors are duly elected or appointed and qualified.

         1.6 Effect on Capital  Stock.  By virtue of the Merger and  without any
action on the part of Merger Sub,  Target or the holders of any of the following
securities:

                  a.  Conversion of Target Common Stock.  At the Effective Time,
each share of Target Common Stock issued and  outstanding  immediately  prior to
the Effective  Time (other than any shares of Target Common Stock to be canceled
pursuant to Section 1.6(b)) will be canceled and  extinguished  and be converted
automatically  into the right to receive thirteen dollars and thirty-five  cents
($13.35) (the "Merger Consideration").

                  b.  Cancellation  of Target  Common Stock Owned by Acquiror or
Target.  At the Effective Time, all shares of Target Common Stock that are owned
by Target as  treasury  stock and each  share of Target  Common  Stock  owned by
Acquiror or any direct or indirect  wholly  owned  subsidiary  of Acquiror or of
Target   immediately   prior  to  the  Effective  Time  shall  be  canceled  and
extinguished without any conversion thereof.

                  c. Capital  Stock of Merger Sub. At the Effective  Time,  each
share of Common Stock,  no par value,  of Merger Sub ("Merger Sub Common Stock")
issued  and  outstanding  immediately  prior  to the  Effective  Time  shall  be
converted   into  and  exchanged  for  one  validly   issued,   fully  paid  and
nonassessable   share  of  Common  Stock,  $.01  par  value,  of  the  Surviving
Corporation.  Each stock  certificate of Merger Sub evidencing  ownership of any
such shares shall continue to evidence ownership of such shares of capital stock
of the Surviving Corporation.

                  d.   Adjustments   to   Merger   Consideration.   The   Merger
Consideration shall be appropriately adjusted to reflect fully the effect of any
stock  split,   reverse  split,  stock  dividend   (including  any  dividend  or
distribution   of   securities    convertible   into   Target   Common   Stock),
reorganization,  recapitalization  or other like change  with  respect to Target
Common Stock occurring after the date hereof and prior to the Effective Time.

         1.7 Surrender of Certificates.

                  a. Exchange Agent. The First National Bank of Boston shall act
as exchange agent (the "Exchange Agent") in the Merger.

                  b.  Acquiror to Provide  Cash.  Promptly  after the  Effective
Time,  Acquiror  shall deliver to the Exchange  Agent for exchange in accordance
with this Article 1, through such  reasonable  procedures as Acquiror may adopt,
cash in an amount sufficient to permit payment (i) pursuant to Section 1.6(a) in
exchange for shares of Target Common Stock outstanding  immediately prior to the
Effective Time and (ii) pursuant to Section 5.9 upon cancellation of outstanding
vested options to acquire shares of Target Common Stock.


                                      -3-


                  c. Exchange Procedures. Promptly after the Effective Time, the
Surviving  Corporation  shall  cause to be mailed to each  bolder of record of a
certificate or certificates (the "Certificates")  which immediately prior to the
Effective  Time  represented  outstanding  shares of Target Common Stock,  whose
shares were  converted  into the right to receive cash  pursuant to Section 1.6,
(i) a  letter  of  transmittal  (which  shall  specify  that  delivery  shall be
effected,  and risk of loss and title to the Certificates  shall pass, only upon
receipt of the Certificates by the Exchange Agent, and shall be in such form and
have  such  other  provisions  as  Acquiror  may  reasonably  specify)  and (ii)
instructions  for use in effecting the surrender of the Certificates in exchange
for cash. Upon surrender of a Certificate for cancellation to the Exchange Agent
or to such other agent or agents as may be appointed by Acquiror,  together with
such letter of  transmittal,  duly completed and validly  executed in accordance
with the instructions  thereto, the holder of such Certificate shall be entitled
to receive in exchange  therefor cash representing the payment which such holder
has the right to  receive  pursuant  to  Section  1.6,  and the  Certificate  so
surrendered shall forthwith be canceled. Until so surrendered,  each outstanding
Certificate  that,  prior to the Effective  Time,  represented  shares of Target
Common Stock will be deemed from and after the Effective Time, for all corporate
purposes,  other than the payment of dividends, to evidence the right to receive
an amount in cash in accordance with Section 1.6.

                  d. Transfers of Ownership.  If any payment pursuant to Section
1.6 is to be made to a name other than that in which the Certificate surrendered
in  exchange  therefor  is  registered,  it will be a  condition  of the payment
thereof  that the  Certificate  so  surrendered  will be properly  endorsed  and
otherwise  in proper  form for  transfer  and that the  person  requesting  such
payment will have paid to Acquiror or any agent designated by it any transfer or
other  taxes  required  by reason of the  payment of such cash to any name other
than  that  of  the  registered  holder  of  the  Certificate  surrendered,   or
established to the  satisfaction of Acquiror or any agent  designated by it that
such tax has been paid or is not payable.

                  e. No Liability.  Notwithstanding  anything to the contrary in
this Section 1.7, none of the Exchange Agent,  the Surviving  Corporation or any
party  hereto  shall be liable to any person for any amount  properly  paid to a
public  official  pursuant  to any  applicable  abandoned  property,  escheat or
similar law.

         1.8 No Further  Ownership  Rights in Target Common Stock. All cash paid
upon the  surrender  for exchange of shares of Target Common Stock in accordance
with the terms hereof shall be deemed to have been paid in full  satisfaction of
all rights  pertaining to such shares of Target Common Stock, and there shall be
no further registration of transfers on the records of the Surviving Corporation
of shares of Target Common Stock which were outstanding immediately prior to the
Effective Time. If, after the Effective Time,  Certificates are presented to the
Surviving  Corporation  for any reason,  they shall be canceled and exchanged as
provided in this Article I.

         1.9  Lost,  Stolen  or  Destroyed   Certificates.   In  the  event  any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
pay in exchange for such lost, stolen or destroyed Certificates, upon the making
of an affidavit of that fact by the holder  thereof,  such amount in cash as may
be required pursuant to Section 1.6;  provided,  however,  that Acquiror 



                                      -4-



may, in its  discretion  and as a condition  precedent to the issuance  thereof,
require the owner of such lost,  stolen or destroyed  Certificates  to deliver a
bond in such sum as it may reasonably direct as indemnity against any claim that
may be made against  Acquiror,  the Surviving  Corporation or the Exchange Agent
with respect to the Certificates alleged to have been lost, stolen or destroyed.

                                   
         1.10 Taking of Necessary Action;  Further Action. If, at any time after
the Effective  Time,  any further  action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving  Corporation  with full
right, title and possession to all assets, property, rights, privileges,  powers
and  franchises  of Target and Merger Sub, the officers and  directors of Target
and Merger Sub are fully authorized in the name of their respective corporations
or otherwise to take,  and will take, all such lawful and necessary  action,  so
long as such action is not inconsistent with this Agreement.



                                   ARTICLE II

                    REPRESENTATIONS AND WARRANTIES OF TARGET
                    ----------------------------------------

         In this  Agreement,  any reference to any event,  change,  condition or
effect being  "material"  with respect to any entity or group of entities  means
any  material  event,  change,  condition  or effect  related  to the  condition
(financial or otherwise),  properties,  assets  (including  intangible  assets),
liabilities,  business,  operations  or results of  operations of such entity or
group of entities.  In this  Agreement,  any  reference  to a "Material  Adverse
Effect" with respect to any entity or group of entities means any event,  change
or effect that is materially adverse to the condition  (financial or otherwise),
properties,  assets, liabilities,  business, operations or results of operations
of such entity and its subsidiaries, taken as a whole; provided, however, that a
"Material  Adverse  Effect" with respect to Target shall not include any adverse
effect on the  revenues or gross  margins of Target (or the direct  consequences
thereof)  following the date of this Agreement  which is attributable to a delay
of,  reduction in or  cancellation  or change in the terms of product  orders by
customers of Target.  In the event of any  litigation  regarding  the  foregoing
provision,  Target  shall be  required  to  sustain  the  burden  of  reasonably
demonstrating that any such delay, reduction, cancellation or change is directly
attributable to the transactions contemplated by this Agreement.

         In this Agreement,  any reference to a party's  "knowledge"  means such
party's actual  knowledge after  reasonable  inquiry of officers,  directors and
other employees of such party charged with senior  administrative or operational
responsibility  for such  matters.  Also,  for  purposes of this Article II, the
transactions  contemplated by the Asset Purchase Agreement,  the Preferred Stock
Purchase and Noteholder Rights Agreement and the MICA License (as such terms are
defined in the Asset Purchase Agreement) shall not be deemed to be "transactions
contemplated by this Agreement."

         Except as disclosed in a document of even date  herewith and  delivered
by Target to Acquiror  prior to the execution and delivery of this Agreement and
referring to the  representations  and warranties in this Agreement (the "Target
Disclosure  Schedule")  and except 

                                      -5-


for (i) the effect of the  execution by Target of the Asset  Purchase  Agreement
and the Preferred Stock Purchase and Noteholder  Rights  Agreement  concurrently
with the execution of this Agreement,  (ii) Target's agreement to consummate the
transactions,  and  execute and perform  the other  documents  and  instruments,
contemplated  by such  other  agreements  (including,  without  limitation,  the
execution and delivery of the MICA License),  and (iii) Target's  performance of
its  obligations  under such other  agreements (all such matters taken together,
the "Pre-Closing Asset Transaction"), Target represents and warrants to Acquiror
and Merger Sub as follows:

         2.1   Organization,   Standing  and  Power.  Each  of  Target  and  its
subsidiaries  is a  corporation  duly  organized,  validly  existing and in good
standing under the laws of its jurisdiction of organization.  Each of Target and
its  subsidiaries  has the corporate power to own its properties and to carry on
its business as now being  conducted and as proposed to be conducted and is duly
qualified to do business and is in good standing in each  jurisdiction  in which
the  failure  to be so  qualified  and in good  standing  would  have a Material
Adverse  Effect  on  Target.  Target  has  delivered  (or as to  the  subsidiary
documents,  made available) a true and correct copy of the Restated  Articles of
Incorporation,  as amended (the  "Articles of  Incorporation"),  and Bylaws,  as
amended,  or other charter documents,  as applicable,  of Target and each of its
subsidiaries,  each as amended to date, to Acquiror.  Neither  Target nor any of
its  subsidiaries  is in violation of any of the  provisions  of its Articles of
Incorporation or Bylaws or equivalent  organizational  documents.  Target is the
record or beneficial owner of all outstanding shares of capital stock of each of
its subsidiaries and all such shares are duly authorized,  validly issued, fully
paid and  nonassessable.  All of the outstanding shares of capital stock of each
such subsidiary are owned by Target free and clear of all liens, charges, claims
or  encumbrances  or rights of others.  There are no outstanding  subscriptions,
options,  warrants, puts, calls, rights,  exchangeable or convertible securities
or other  commitments  or agreements of any character  relating to the issued or
unissued capital stock or other securities of any such subsidiary,  or otherwise
obligating  Target or any such subsidiary to issue,  transfer,  sell,  purchase,
redeem or  otherwise  acquire any such  securities.  Except as  disclosed in the
Target SEC Documents  (as defined in Section  2.4),  Target does not directly or
indirectly own any equity or similar interest in, or any interest convertible or
exchangeable  or  exercisable  for,  any  equity or  similar  interest  in,  any
corporation, partnership, joint venture or other business association or entity.

         2.2 Capital Structure.  The authorized capital stock of Target consists
of 40,000,000  shares of Common Stock, no par value,  and no shares of Preferred
Stock,  no par value, of which there were issued and outstanding as of the close
of business on July 18, 1996, 13,806,692 shares of Common Stock and no shares of
Preferred  Stock.  There are no other  outstanding  shares of  capital  stock or
voting  securities of Target and no outstanding  commitments to issue any shares
of capital  stock or voting  securities of Target after July 18, 1996 other than
pursuant to the Option  Agreement,  the  exercise of options or purchase  rights
outstanding as of such date under (i) the following stock option plans of Target
(collectively,  the  "Target  Option  Plans"):  the Target 1985  Employee  Stock
Incentive  Program (the "1985 Plan),  the assumed 1987 Octocom Stock Option Plan
(the "1987 Plan"),  the 1994 Non-Employee  Director Stock Option Plan (the "1994
Plan") and the 1995 Stock  Option Plan (the "1995 Plan") or (ii) the Target 1990
Employee  Stock Purchase Plan (the "Target  ESPP").  All  outstanding  shares of
Target  Common  Stock  are  duly  authorized,  validly  issued,  fully  paid and
nonassessable and are free of any liens or 


                                      -6-


encumbrances other than any liens or encumbrances created by or imposed upon the
holders thereof and restrictions imposed by applicable  securities laws, and are
not subject to preemptive  rights or rights of first refusal created by statute,
the  Articles of  Incorporation  or Bylaws of Target or any  agreement  to which
Target is a party or by which it is bound.  As of the close of  business on July
18, 1996,  Target has reserved (i) 4,300,225 shares of Common Stock for issuance
to  employees,  consultants  and  directors  pursuant to the Target Stock Option
Plans, of which 1,969,722  shares have been issued pursuant to option  exercises
or  direct  stock  purchases,  1,761,062  shares  are  subject  to  outstanding,
unexercised  options,  and no shares are subject to  outstanding  stock purchase
rights,  and (ii)  660,000  shares of Common  Stock for  issuance  to  employees
pursuant to the Target ESPP,  of which  452,663  shares have been issued.  Since
July 18, 1996, Target has not (i) issued or granted additional options under the
Target Stock Option Plans, or (ii) accepted  contributions  to or enrollments in
the Target ESPP.  Except for (i) the rights created  pursuant to this Agreement,
the Option  Agreement,  the Employment  Agreements  listed in Schedule 2.14, the
Target  Stock  Option  Plans  and the  Target  ESPP and (ii)  Target's  right to
repurchase any unvested shares under the Target Stock Option Plans, there are no
other  options,  warrants,  calls,  rights,  commitments  or  agreements  of any
character to which Target is a party or by which it is bound  obligating  Target
to issue, deliver, sell, repurchase or redeem, or cause to be issued, delivered,
sold,  repurchased  or  redeemed,  any  shares  of  capital  stock of  Target or
obligating Target to grant, extend,  accelerate the vesting of, change the price
of, or otherwise  amend or enter into any such  option,  warrant,  call,  right,
commitment  or  agreement.  There are no  contracts,  commitments  or agreements
relating to voting,  purchase or sale of Target's  capital  stock (i) between or
among  Target  and any of its  shareholders  and  (ii) to the  best of  Target's
knowledge,  between  or  among  any of  Target's  shareholders,  except  for the
shareholders who have executed the Voting Agreements referred to in Recital D of
this Agreement. The terms of the Target Stock Option Plans permit the assumption
or substitution of options to purchase Acquiror Common Stock as provided in this
Agreement,  without the  consent or approval of the holders of such  securities,
the Target  shareholders,  or  otherwise  and  without any  acceleration  of the
exercise  schedule or vesting  provisions in effect for those options (except as
otherwise  provided  in one or  more  of the  Employment  Agreements  listed  in
Schedule 2.14).  The current  "Purchase  Period" (as defined in the Target ESPP)
commenced  under  the  Target  ESPP on June 1,  1996 and  will end  prior to the
Effective Time as provided in this Agreement, and except for the purchase rights
granted  on such  commencement  date to  participants  in the  current  Purchase
Period,  there are no other  purchase  rights or options  outstanding  under the
Target  ESPP.  True  and  complete  copies  of all  agreements  and  instruments
presently in effect relating to or issued under the Target Stock Option Plans or
Target  ESPP  have  been  delivered  or made  available  to  Acquiror  and  such
agreements and instruments have not been amended, modified or supplemented,  and
there are no  agreements  to amend,  modify or  supplement  such  agreements  or
instruments in any case from the form delivered to Acquiror.

         2.3 Authority.  Target has all requisite  corporate power and authority
to enter into this  Agreement and the Option  Agreement  and to  consummate  the
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the Option  Agreement  and the  consummation  of the  transactions
contemplated  hereby and  thereby  have been duly  authorized  by all  necessary
corporate  action on the part of Target,  subject  only to the  approval  of the
Merger by Target's  shareholders as contemplated by Section 6.1(a). Each of this
Agreement  and the Option 


                                      -7-
 

Agreement  has been duly executed and  delivered by Target and  constitutes  the
valid and binding obligation of Target enforceable  against Target in accordance
with its terms except as  enforceability  may be limited by bankruptcy and other
laws  affecting  the rights and  remedies  of  creditors  generally  and general
principles  of equity.  The  execution  and delivery of this  Agreement  and the
Option  Agreement by Target does not, and the  consummation of the  transactions
contemplated  hereby or by the Option  Agreement  will not,  conflict  with,  or
result in any violation of, or default under (with or without notice or lapse of
time,  or  both),  or give  rise  to a right  of  termination,  cancellation  or
acceleration of any obligation or loss of any benefit under (i) any provision of
the Articles of Incorporation or Bylaws of Target or any of its subsidiaries, as
amended,  or (ii) any material  mortgage,  indenture,  lease,  contract or other
agreement or  instrument,  permit,  concession,  franchise,  license,  judgment,
order, decree, statute, law, ordinance,  rule or regulation applicable to Target
or any of its  subsidiaries or any of their  properties or assets,  except where
such conflict,  violation,  default,  termination,  cancellation or acceleration
with respect to the  foregoing  provisions  of (ii) would not have had and would
not  reasonably  be expected  to have a Material  Adverse  Effect on Target.  No
consent,  approval,  order or authorization of, or registration,  declaration or
filing  with,   any  court,   administrative   agency  or  commission  or  other
governmental authority or instrumentality ("Governmental Entity") is required by
or with  respect to Target or any of its  subsidiaries  in  connection  with the
execution  and  delivery  of  this  Agreement,  the  Option  Agreement,  or  the
consummation of the transactions contemplated hereby and thereby, except for (i)
the filing of the  Agreement  of Merger as  provided  in Section  1.2,  (ii) the
filing with the Securities and Exchange  Commission (the "SEC") and the National
Association of Securities Dealers,  Inc. (the "NASD") of the Proxy Statement (as
defined in Section 2.23) relating to the Target Shareholders Meeting (as defined
in  Section  2.21),  (iii)  such  other  filings  as may be  required  under the
Securities  Exchange Act of 1934, as amended (the  "Securities  Exchange  Act"),
(iv)  such   consents,   approvals,   orders,   authorizations,   registrations,
declarations  and filings as may be required under  applicable  state securities
laws and the securities laws of any foreign country,  (v) such filings as may be
required  under the  Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976, as
amended  ("HSR"),  and  (vi)  such  other  consents,  authorizations,   filings,
approvals and  registrations  which,  if not obtained or made,  would not have a
Material Adverse Effect on Target and would not prevent,  or materially alter or
delay any of the  transactions  contemplated  by this  Agreement  or the  Option
Agreement.

         2.4 SEC Documents;  Financial Statements.  Target has furnished or made
available  to  Acquiror  a true and  complete  copy of each  statement,  report,
registration  statement  (with the prospectus in the form filed pursuant to Rule
424(b) of the  Securities  Act of 1933,  as  amended  (the  "Securities  Act")),
definitive  proxy  statement and other filing filed with the SEC by Target since
April 27, 1990,  and,  prior to the Effective  Time,  Target will have furnished
Acquiror  with, or made available to Acquiror,  true and complete  copies of any
additional  documents  filed with the SEC by Target prior to the Effective  Time
(collectively, the "Target SEC Documents"). In addition, Target has delivered or
made available to Acquiror all exhibits to the Target SEC Documents  filed prior
to the date hereof,  and will  promptly  deliver to Acquiror all exhibits to any
additional Target SEC Documents filed prior to the Effective Time. All documents
required to be filed as exhibits to the Target SEC Documents have been so filed,
and all  material  contracts  so filed as exhibits are in full force and effect,
except  those which have expired or been  terminated  in  accordance  with their
terms, and neither Target nor any of its subsidiaries is in default  thereunder,


                                      -8-


except  where  default  would not have a Material  Adverse  Effect.  As of their
respective  filing  dates,  the Target SEC  Documents  complied in all  material
respects with the requirements of the Securities Exchange Act and the Securities
Act, and as of their respective dates none of the Target SEC Documents contained
any  untrue  statement  of a material  fact or omitted to state a material  fact
required to be stated therein or necessary to make the statements  made therein,
in light of the circumstances in which they were made, not misleading, except to
the extent corrected by a subsequently filed Target SEC Document.  The financial
statements of Target,  including the notes  thereto,  included in the Target SEC
Documents (the "Target  Financial  Statements") were complete and correct in all
material  respects  as of their  respective  dates,  complied  as to form in all
material respects with applicable accounting requirements and with the published
rules and  regulations  of the SEC with respect  thereto as of their  respective
dates, and have been prepared in accordance with generally  accepted  accounting
principles  applied on a basis consistent  throughout the periods  indicated and
consistent  with each other (except as may be indicated in the notes thereto or,
in the case of unaudited  statements included in Quarterly Reports on Form 10-Q,
as permitted by Form 10-Q of the SEC). The Target  Financial  Statements  fairly
present the consolidated financial condition and operating results of Target and
its subsidiaries at the dates and during the periods indicated therein (subject,
in the case of unaudited statements, to normal, recurring year-end adjustments).
There has been no change in Target  accounting  policies  except as described in
the notes to the Target Financial Statements.

         2.5  Absence of Certain  Changes.  Since  March 30,  1996 (the  "Target
Balance Sheet Date"),  Target has conducted its business in the ordinary  course
consistent with past practice and there has not occurred:  (i) any change, event
or  condition  (whether or not covered by  insurance)  that has  resulted in, or
might  reasonably be expected to result in, a Material Adverse Effect to Target;
(ii) any acquisition, sale or transfer of any material asset of Target or any of
its  subsidiaries  other than in the ordinary  course of business and consistent
with past practice; (iii) any material change in accounting methods or practices
(including  any change in  depreciation  or  amortization  policies or rates) by
Target  or  any  material  revaluation  by  Target  of  any of its or any of its
subsidiaries'  assets;  (iv) any  declaration,  setting  aside,  or payment of a
dividend  or other  distribution  with  respect to the shares of Target,  or any
direct or indirect redemption, purchase or other acquisition by Target of any of
its shares of capital stock; (v) any material contract entered into by Target or
any of its  subsidiaries,  other than in the ordinary  course of business and as
provided to Acquiror,  or any material  amendment or termination  of, or default
under,  any material  contract to which Target or any of its  subsidiaries  is a
party or by which it is bound; or (vi) any negotiation or agreement by Target or
any of its  subsidiaries  to do any of the  things  described  in the  preceding
clauses  (i)  through  (v)  (other  than  negotiations  with  Acquiror  and  its
representatives regarding the transactions contemplated by this Agreement).

         2.6  Absence  of  Undisclosed  Liabilities.   Target  has  no  material
obligations  or  liabilities  of any  nature  (matured  or  unmatured,  fixed or
contingent)  other than (i) those set forth or  adequately  provided  for in the
Balance Sheet included in Target's  Quarterly Report on Form 10-Q for the period
ended March 30, 1996 (the "Target  Balance  Sheet"),  (ii) those incurred in the
ordinary  course of  business  and not  required  to be set forth in the  Target
Balance  Sheet  under  generally  accepted  accounting  principles,  (iii) those
incurred in the ordinary  course of business


                                      -9-


since the Target Balance Sheet Date and consistent with past practice;  and (iv)
those incurred in connection with the execution of this Agreement and the Option
Agreement.

         2.7  Litigation.  There is no private  or  governmental  action,  suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal,  foreign or domestic,  or, to the knowledge of Target or any of its
subsidiaries,  threatened  against Target or any of its  subsidiaries  or any of
their respective properties or any of their respective officers or directors (in
their  capacities  as  such)  that,  individually  or in  the  aggregate,  could
reasonably be expected to have a Material Adverse Effect on Target.  There is no
judgment, decree or order against Target or any of its subsidiaries,  or, to the
knowledge of Target and its subsidiaries,  any of their respective  directors or
officers (in their  capacities  as such),  that could  reasonably be expected to
prevent, enjoin, alter or materially delay any of the transactions  contemplated
by this  Agreement,  or that could  reasonably  be  expected  to have a Material
Adverse Effect on Target.

         2.8  Restrictions  on  Business   Activities.   There  is  no  material
agreement,  judgment,  injunction, order or decree binding upon Target or any of
its subsidiaries which has or reasonably could be expected to have the effect of
prohibiting or materially  impairing any current or future business  practice of
Target or any of its subsidiaries,  any acquisition of property by Target or any
of  its  subsidiaries  or  the  conduct  of  business  by  Target  or any of its
subsidiaries.

         2.9  Governmental  Authorization.  Target and each of its  subsidiaries
have  obtained  each  federal,  state,  county,  local or  foreign  governmental
consent, license, permit, grant, or other authorization of a Governmental Entity
(i) pursuant to which Target or any of its  subsidiaries  currently  operates or
holds any  interest in any of its  properties  or (ii) that is required  for the
operation of Target's or any of its subsidiaries' business or the holding of any
such interest ((i) and (ii) herein collectively called "Target Authorizations"),
and all of such Target Authorizations are in full force and effect, except where
the  failure  to  obtain  or have any of such  Target  Authorizations  could not
reasonably be expected to have a Material Adverse Effect on Target.

         2.10 Title to Property. Target and its subsidiaries have good and valid
title to all of their respective properties, interests in properties and assets,
real and personal,  reflected in the Target  Balance Sheet or acquired after the
Target Balance Sheet Date (except properties, interests in properties and assets
sold or  otherwise  disposed  of since  the  Target  Balance  Sheet  Date in the
ordinary  course of business),  or in the case of leased  properties and assets,
valid leasehold interests in, free and clear of all mortgages,  liens,  pledges,
charges or encumbrances of any kind or character, except (i) the lien of current
taxes not yet due and  payable,  (ii)  such  imperfections  of title,  liens and
easements as do not and will not  materially  detract from or interfere with the
use  of the  properties  subject  thereto  or  affected  thereby,  or  otherwise
materially  impair business  operations  involving such properties,  (iii) liens
securing  debt which is reflected on the Target  Balance  Sheet,  and (iv) liens
that in the  aggregate  would not have a Material  Adverse  Effect.  The plants,
property  and  equipment  of Target  and its  subsidiaries  that are used in the
operations  of their  businesses  are in good  operating  condition  and repair,
ordinary wear and tear excepted. All properties used in the operations of Target
and its  subsidiaries  are  reflected in the Target  Balance Sheet to the extent
generally  accepted  accounting  principles  require  the same to be  reflected.


                                      -10-

Schedule 2.10  identifies each parcel of real property owned or leased by Target
or any of its subsidiaries.

         2.11  Intellectual Property.

                  a.  Target  and  its  subsidiaries  own,  or are  licensed  or
otherwise  possess legally  enforceable  rights to use all patents,  trademarks,
trade  names,  service  marks,   copyrights,   and  any  applications  therefor,
maskworks,   net  lists,  schematics,   technology,   know-how,  trade  secrets,
inventory,   ideas,  algorithms,   processes,   computer  software  programs  or
applications  (in both  source  code and object  code  form),  and  tangible  or
intangible proprietary  information or material  ("Intellectual  Property") that
are used in the  business of Target and its  subsidiaries,  except to the extent
that the failure to have such rights  have not had and would not  reasonably  be
expected to have a Material Adverse Effect on Target.

                  b. Schedule 2.11 lists (i) all patents and patent applications
and all registered and unregistered  trademarks,  trade names and service marks,
registered and unregistered copyrights, and maskworks, which Target considers to
be material to its business and included in the Intellectual Property, including
the jurisdictions in which each such Intellectual Property right has been issued
or registered or in which any application for such issuance and registration has
been filed,  (ii) all  licenses,  sublicenses  and other  agreements as to which
Target is a party and  pursuant  to which any  person is  authorized  to use any
Intellectual  Property (except for non-material  licenses entered into by Target
in the ordinary  course of business),  and (iii) all licenses,  sublicenses  and
other  agreements  as to which Target is a party and pursuant to which Target is
authorized to use any third party patents,  trademarks or copyrights,  including
software ("Third Party Intellectual Property Rights") which are incorporated in,
are, or form a part of any Target product that is material to its business.

                  c. There is no unauthorized use,  disclosure,  infringement or
misappropriation  of any  Intellectual  Property  rights of Target or any of its
subsidiaries, any trade secret material to Target or any of its subsidiaries, or
any Intellectual  Property right of any third party to the extent licensed by or
through  Target or any of its  subsidiaries,  by any third party,  including any
employee or former employee of Target or any of its subsidiaries. Neither Target
nor any of its  subsidiaries  has entered into any  agreement  to indemnify  any
other person against any charge of  infringement of any  Intellectual  Property,
other than  indemnification  provisions  contained in purchase  orders and other
agreements arising in the ordinary course of business.

                  d. Target is not, nor will it be as a result of the  execution
and delivery of this Agreement or the performance of its obligations  under this
Agreement,  in breach of any license,  sublicense or other agreement relating to
the  Intellectual  Property or Third Party  Intellectual  Property  Rights,  the
breach of which would have a Material Adverse Effect on Target.

                  e. All  patents,  registered  trademarks,  service  marks  and
copyrights held by Target are valid and subsisting. Target (i) is not a party to
any pending suit, action or proceeding which involves a claim of infringement of
any patents,  trademarks,  service  marks,  copyrights or violation of any trade
secret or other  proprietary  right of any third  party and (ii) has not brought



                                      -11-


any action,  suit or proceeding for  infringement  of  Intellectual  Property or
breach of any license or agreement involving  Intellectual  Property against any
third party. The manufacture,  marketing, licensing or sale of Target's products
does not infringe any patent, trademark,  service mark, copyright,  trade secret
or other  proprietary  right of any third party,  except where such infringement
would not have a Material Adverse Effect on Target.

                  f.  Target has  secured  valid  written  assignments  from all
consultants  and employees who  contributed  to the creation or  development  of
Intellectual  Property of the rights to such  contributions that Target does not
already own by operation of law.

                  g. Target believes it has taken all reasonable and appropriate
steps to protect and preserve the  confidentiality of all Intellectual  Property
not  otherwise  protected  by  patents,  or  patent  applications  or  copyright
("Confidential  Information").  To Target's  knowledge,  all use,  disclosure or
appropriation of Confidential Information owned by Target by or to a third party
has been pursuant to the terms of a written  agreement  between  Target and such
third party. To Target's  knowledge,  all use,  disclosure or  appropriation  of
Confidential Information not owned by Target has been pursuant to the terms of a
written agreement between Target and the owner of such Confidential Information,
or is otherwise lawful.

         2.12     Environmental Matters.

                  a.  The following terms shall be defined as follows:

                           (1)  "Environmental  and Safety  Laws" shall mean any

         require  reporting  with  respect  to,  or list or define  air,  water,
         groundwater,  solid waste,  hazardous or toxic  substances,  materials,

         improvements on the Property of Target or its subsidiaries.

                  b. Target  represents and warrants  that,  except in all cases

required to be issued and are in full  compliance  with the terms and conditions
of those permits.

         2.13 Taxes.  Except  with  respect to such  exceptions  as would not be
reasonably expected to have a Material Adverse Effect on Target:

                  Target has timely  filed all Tax Returns  required to be filed
by it, has timely filed or caused to be timely filed all Tax Returns required to
be filed by each of its subsidiaries for periods during which such  corporations
were subsidiaries of Target,  has paid all Taxes shown thereon to be due and has
provided  adequate  accruals in accordance  with generally  accepted  accounting

not be required to include any material adjustment in Taxable income for any Tax
period  (or  portion  thereof)  pursuant  to  Section  481  of the  Code  or any

         2.14     Employee Benefit Plans.

                  a. Schedule 2.14 lists, with respect to Target, any subsidiary
of Target  and any trade or  business  (whether  or not  incorporated)  which is
treated as a single  employer  with  Target (an  "ERISA  Affiliate")  within the
meaning  of  Section  414(b),  (c),  (m) or (o) of the  Code,  (i) all  material
employee  benefit  plans (as defined in Section 3(3) of the Employee  Retirement
Income  Security  Act of  1974,  as  amended  ("ERISA")),  (ii)  each  loan to a
non-officer  employee in excess of $50,000,  loans to officers and directors and
any stock option,  stock  purchase,  phantom stock,  stock  appreciation  right,
supplemental retirement,  severance,  sabbatical,  medical, dental, vision care,
disability,  employee  relocation,  cafeteria  benefit  (Code  section  125)  or
dependent care (Code Section 129), life insurance or accident  insurance  plans,
programs or arrangements,  (iii) all bonus,  pension,  profit sharing,  savings,
deferred compensation or incentive plans,  programs or arrangements,  (iv) other
fringe or employee benefit plans,  programs or arrangements that apply to senior
management of Target and that do not generally  apply to all employees,  and (v)
any  current  or  former  employment  or  executive  compensation  or  severance
agreements,  written or otherwise, as to which unsatisfied obligations of Target
of greater than  $50,000  remain for the benefit of, or relating to, any present
or former  employee,  consultant  or director of Target  (together,  the "Target
Employee Plans").

                  b.  Target  has  furnished  to  Acquiror a copy of each of the
Target  Employee Plans and related plan documents  (including  trust  documents,
insurance policies or contracts,  employee  booklets,  summary plan descriptions
and other authorizing documents, and, to the extent still in its possession, any
material employee communications relating thereto) and has, with respect to each
Target Employee Plan which is subject to ERISA reporting requirements,  provided
copies of the Form 5500 reports filed for the last three plan years.  Any Target
Employee  Plan  intended to be qualified  under  Section  401(a) of the Code has
either  obtained  from the Internal  Revenue  Service a favorable  determination
letter as to its qualified  status under the Code,  including all  amendments to
the Code effected by the Tax Reform Act of 1986 and subsequent  legislation,  or
has applied to the  Internal  Revenue  Service for such a  determination  letter
prior to the  expiration  of the  requisite  period  under  applicable  Treasury
Regulations or Internal  Revenue  Service  pronouncements  in which to apply for
such  determination  letter  and to make any  amendments  necessary  to obtain a
favorable determination. Target has also furnished Acquiror with the most recent
Internal Revenue Service  determination  letter issued with respect


                                      -14-


to each such Target  Employee  Plan, and nothing has occurred since the issuance
of each such letter which could  reasonably be expected to cause the loss of the
tax-qualified status of any Target Employee Plan subject to Code Section 401(a).

                  c. (i) None of the Target  Employee Plans promises or provides
retiree medical or other retiree welfare benefits to any person;  (ii) there has
been no  "prohibited  transaction,"  as such term is defined  in Section  406 of
ERISA and Section 4975 of the Code,  with respect to any Target  Employee  Plan,
which could reasonably be expected to have, in the aggregate, a Material Adverse
Effect; (iii) each Target Employee Plan has been administered in accordance with
its terms and in  compliance  with the  requirements  prescribed  by any and all
statutes,  rules and regulations (including ERISA and the Code), except as would
not have,  in the  aggregate,  a Material  Adverse  Effect,  and Target and each
subsidiary or ERISA  Affiliate  have  performed all  obligations  required to be
performed  by them under,  are not in any respect in default  under or violation
of, and have no knowledge of any default or violation by any other party to, any
of the Target  Employee Plans,  which default or violation  could  reasonably be
expected to have a Material  Adverse  Effect on Target;  (iv) neither Target nor
any  subsidiary or ERISA  Affiliate is subject to any liability or penalty under
Sections  4976  through 4980 of the Code or Title I of ERISA with respect to any
of the Target  Employee  Plans,  which  liability or penalty could be reasonably
expected  to  have a  Material  Adverse  Effect  on  Target;  (v)  all  material
contributions required to be made by Target or any subsidiary or ERISA Affiliate
to any Target  Employee  Plan have been made on or before  their due dates and a
reasonable  amount has been accrued for  contributions  to each Target  Employee
Plan for the current plan years; (vi) with respect to each Target Employee Plan,
no "reportable event" within the meaning of Section 4043 of ERISA (excluding any
such event for which the  thirty  (30) day notice  requirement  has been  waived
under the  regulations  to  Section  4043 of ERISA) nor any event  described  in
Section 4062,  4063 or 4041 of ERISA has occurred;  and (vii) no Target Employee
Plan is covered by, and neither Target nor any subsidiary or ERISA Affiliate has
incurred  or expects to incur any  liability  under Title IV of ERISA or Section
412 of the Code.  With respect to each Target  Employee Plan subject to ERISA as
either an employee  pension  plan within the meaning of Section 3(2) of ERISA or
an employee  welfare  benefit  plan within the meaning of Section 3(1) of ERISA,
Target has  prepared in good faith and timely filed all  requisite  governmental
reports  (which were true and correct as of the date filed) and has properly and
timely  filed and  distributed  or posted all notices  and reports to  employees
required to be filed,  distributed  or posted  with  respect to each such Target
Employee  Plan,  except  where the failure to take such action  would not have a
Material Adverse Effect on Target. No suit, administrative proceeding, action or
other  litigation  has been  brought,  or to the best  knowledge  of  Target  is
threatened,  against or with respect to any such Target Employee Plan, including
any audit or inquiry by the IRS or United States  Department  of Labor.  Neither
Target nor any Target  subsidiary or other ERISA Affiliate is a party to, or has
made any  contribution  to or  otherwise  incurred  any  obligation  under,  any
"multiemployer plan" as defined in Section 3(37) of ERISA.

                  d. With respect to each Target Employee Plan,  Target and each
of its United States  subsidiaries  have complied with (i) the applicable health
care  continuation  and notice  provisions of the  Consolidated  Omnibus  Budget
Reconciliation Act of 1985 ("COBRA") and the proposed regulations thereunder and
(ii)  the  applicable  requirements  of the  Family  Leave  Act of 


                                      -15-


1993 and the regulations  thereunder,  except to the extent that such failure to
comply would not, in the aggregate, have a Material Adverse Effect.

                  e. The consummation of the  transactions  contemplated by this
Agreement  will not (i) entitle any current or former  employee or other service
provider  of Target,  any Target  subsidiary  or any other  ERISA  Affiliate  to
severance  benefits or any other payment,  except as expressly  provided in this
Agreement,  or (ii)  accelerate the time of payment or vesting,  or increase the
amount of compensation due any such employee or service provider.

                  f. There has been no amendment to, written  interpretation  or
announcement  (whether or not written) by Target, any Target subsidiary or other
ERISA Affiliate  relating to, or change in  participation or coverage under, any
Target Employee Plan which would materially  increase the expense of maintaining
such Plan above the level of expense  incurred with respect to that Plan for the
most recent fiscal year included in Target's financial statements.

         2.15 Certain Agreements  Affected by the Merger.  Neither the execution
and  delivery  of  this  Agreement  nor  the  consummation  of  the  transaction
contemplated  hereby  will  (i)  result  in  any  payment  (including,   without
limitation,  severance,  unemployment  compensation,  golden parachute, bonus or
otherwise)  becoming  due to any  director  or  employee of Target or any of its
subsidiaries,  (ii) materially increase any benefits otherwise payable by Target
or (iii)  result in the  acceleration  of the time of  payment or vesting of any
such benefits.

         2.16  Employee  Matters.  Target  and each of its  subsidiaries  are in
compliance in all respects with all currently  applicable  laws and  regulations
respecting  employment,  discrimination  in employment,  terms and conditions of
employment,  wages,  hours and  occupational  safety and  health and  employment
practices,  and is not engaged in any unfair  labor  practice,  except where the
failure to be in  compliance or the  engagement  in such unfair labor  practices
would not have a Material Adverse Effect on Target.  There are no pending claims
against Target or any of its subsidiaries under any workers compensation plan or
policy or for long term  disability.  Neither Target nor any of its subsidiaries
has any  obligations  under  COBRA  with  respect  to any  former  employees  or
qualifying beneficiaries thereunder,  except for obligations that would not have
a Material Adverse Effect on Target.  There are no controversies  pending or, to
the knowledge of Target or any of its subsidiaries,  threatened,  between Target

laws of its  jurisdiction of  organization.  Each of Acquiror and Merger Sub has
the corporate  power to own its  properties  and to carry on its business as now
being  conducted  and as proposed to be  conducted  and is duly  qualified to do

so  qualified  and in good  standing  would  have a Material  Adverse  Effect on
Acquiror.  Acquiror  has  delivered a true and correct  copy of the  Articles of
Incorporation and Bylaws or other charter documents, as applicable,  of Acquiror
to  Target.  Neither  Acquiror  nor  Merger  Sub is in  violation  of any of the

execution and delivery of this Agreement has been duly executed and delivered by
Acquiror and Merger Sub and  constitutes  the valid and binding  obligations  of
Acquiror and Merger Sub. The  execution  and delivery of this  Agreement do not,
and the consummation of the transactions  contemplated hereby will not, conflict
with, or result in any violation of, or default under (with or without notice or
lapse of time, or both), or give rise to a right of termination, cancellation or
acceleration  of any  obligation or loss of a benefit under (i) any provision of
the Articles of  Incorporation  or Bylaws of Acquiror or Merger Sub, as amended,
or (ii) any material mortgage,  indenture, lease, contract or other agreement or
instrument,  permit,  concession,  franchise,  license, judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to Acquiror or Merger Sub
or their properties or assets, except where such conflict,  violation,  default,
termination,   cancellation  or  acceleration  with  respect  to  the  foregoing
provisions  of (ii) would not have had and would not  reasonably  be expected to
have a Material  Adverse  Effect on  Acquiror.  No consent,  approval,  order or
authorization of, or registration,  declaration or filing with, any Governmental
Entity,  is required by or with respect to Acquiror or Merger Sub in  connection
with the execution and delivery of this  Agreement by Acquiror and Merger Sub or

Section  1.2,  (ii)  any  filings  as may be  required  under  applicable  state
securities  laws and the  securities  laws of any  foreign  country,  (iii) such
filings  as  may  be  required   under  HSR,  and  (iv)  such  other   consents,
authorizations,  filings,  approvals and registrations which, if not obtained or

Effect on  Acquiror.  As of their  respective  filing  dates,  the  Acquiror SEC
Documents  complied  in all  material  respects  with  the  requirements  of the
Securities  Exchange  Act and the  Securities  Act, and none of the Acquiror SEC
Documents  contained any untrue statement of a material fact or omitted to state
a  material  fact  required  to be  stated  therein  or  necessary  to make  the
statements made therein,  in light of the circumstances in which they were made,
not misleading,  except to the extent corrected by a subsequently filed Acquiror
SEC Document. The financial statements of Acquiror, including the notes thereto,
included in the Acquiror SEC Documents  (the  "Acquiror  Financial  Statements")

respect  thereto  as of their  respective  dates,  and  have  been  prepared  in
accordance  with generally  accepted  accounting  principles  applied on a basis
consistent  throughout  the periods  indicated  and  consistent  with each other
(except as may be  indicated  in the notes  thereto or, in the case of unaudited
statements included in Quarterly Reports on Form 10-Q, as permitted by Form 10-Q
of the SEC). The Acquiror  Financial  Statements fairly present the consolidated
financial  condition and operating  results of Acquiror and its  subsidiaries at
the dates and during the  periods  indicated  therein  (subject,  in the case of
unaudited statements, to normal, recurring year-end adjustments). There has been
no change in Acquiror  accounting  policies  except as described in the notes to
the Acquiror Financial Statements.

proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal, foreign or domestic, or, to the knowledge of Acquiror or any of its
subsidiaries,  threatened  against Acquiror or any of its subsidiaries or any of
their respective properties or any of their respective officers or directors (in
their  capacities  as  such)  that,  individually  or in  the  aggregate,  could
reasonably  be  expected  to have a material  adverse  effect on the  ability of
Acquiror to consummate the transactions contemplated by this Agreement. There is
no judgment,  decree or order against Acquiror or any of its subsidiaries or, to
the knowledge of Acquiror or any of its  subsidiaries,  any of their  respective
directors or officers (in their capacities as such) that could prevent,  enjoin,
alter  or  materially  delay  any  of  the  transactions  contemplated  by  this
Agreement,  or that could  reasonably  be  expected  to have a material  adverse
effect on the ability of Acquiror to consummate the transactions contemplated by
this Agreement.

with respect to any information  supplied by Target which is contained in any of
the foregoing documents.

permitted with respect thereto under the terms of the Asset Purchase  Agreement;
provided,  however, that Target agrees that it shall not seek to amend or waive,
or consent to an  amendment or waiver of, any  provision  of the Asset  Purchase
Agreement or the Preferred Stock Purchase and Noteholder Rights Agreement or any
of the forms of  agreement  contemplated  by such  agreements  without the prior
written consent of Acquiror.

         4.2 No  Solicitation.  From and after the date hereof until the earlier
of the Effective Time or the  termination  of this Agreement in accordance  with
Article VII, Target and its subsidiaries and the officers, directors,  employees
or other agents of Target and its subsidiaries will not, directly or indirectly,
(i) take any action to solicit,  initiate or  encourage  any  Takeover  Proposal
(defined  below)  or (ii)  subject  to the  terms of the  immediately  following
sentence, 


                                      -24-


engage in negotiations with, or disclose any nonpublic  information  relating to
Target or any of it subsidiaries  to, or afford access to the properties,  books
or records of Target or any of its  subsidiaries to, any person that has advised
Target that it may be considering making, or that has made, a Takeover Proposal;
provided,  nothing herein shall prohibit Target's Board of Directors from taking
and  disclosing  to Target's  shareholders  a position  with respect to a tender
offer  pursuant to Rules 14d-9 and 14e-2  promulgated  under the  Exchange  Act.
Notwithstanding the immediately  preceding sentence,  if an unsolicited Takeover
Proposal,  or an unsolicited  written expression of interest that can reasonably
be  expected to lead to a Takeover  Proposal,  shall be received by the Board of
Directors  of  Target,  then,  to the extent  the Board of  Directors  of Target
believes in good faith (after consultation with its financial advisor) that such
Takeover Proposal would, if consummated,  result in a transaction more favorable
to Target's  shareholders  from a financial  point of view than the  transaction
contemplated by the Agreement (any such more favorable  Takeover  Proposal being
referred  to in this  Agreement  as a  "Superior  Proposal")  and the  Board  of
Directors of Target  determines  in good faith after  consultation  with outside
legal  counsel  that it  would be  inconsistent  with  the  Board of  Directors'
fiduciary duties to shareholders  under applicable law, Target and its officers,
directors,   employees,   investment  bankers,  financial  advisors,  attorneys,
accountants and other  representatives  retained by it may furnish in connection
therewith  information  and take such other actions as are  consistent  with the
fiduciary obligations of Target's Board of Directors, and such actions shall not
be  considered  a breach of this  Section  4.2 or any other  provisions  of this
Agreement,  provided  that in each such event Target  notifies  Acquiror of such
determination by the Target Board of Directors and provides Acquiror with a true
and complete copy of the Superior  Proposal  received from such third party,  if
the Superior Proposal is in writing,  or a complete written summary thereof,  if
it is not in writing,  and provides  Acquiror with all  documents  containing or
referring to  non-public  information  of Target that are supplied to such third
party;  provided,  further,  that  (A) the  Board of  Directors  of  Target  has
determined,  with the advice of  Target's  investment  bankers,  that such third
party is capable of making a Superior Proposal upon  satisfactory  completion of
such third party's review of the information  supplied by Target,  (B) the third
party has stated that it intends to make a Superior Proposal, (C) Target may not
provide any  non-public  information to any such third party if it has not prior
to the  date  thereof  provided  such  information  to  Acquiror  or  Acquiror's
representatives, and (D) Target provides such non-public information pursuant to
a non-disclosure  agreement  substantially  the same as or otherwise at least as
restrictive on such third party as the Confidentiality Agreement is on Acquiror;
provided,  however,  that  Target  shall  not,  and shall not  permit any of its
officers,  directors,  employees or other representatives to agree to or endorse
any  Takeover  Proposal  unless  Target  shall have  terminated  this  Agreement
pursuant to Section  7.1(e) and paid  Acquiror  all amounts  payable to Acquiror
pursuant to Section  7.3(b).  Target will promptly notify Acquiror after receipt
of any Takeover  Proposal or any notice that any person is considering  making a
Takeover Proposal or any request for non-public  information  relating to Target
or any of its subsidiaries or for access to the properties,  books or records of
Target or any of its  subsidiaries by any person that has advised Target that it
may be considering  making,  or that has made, a Takeover Proposal and will keep
Acquiror fully informed of the status and details of any such Takeover  Proposal
notice,  request or any  correspondence  or  communications  related thereto and
shall provide  Acquiror with a true and complete copy of such Takeover  Proposal
notice or request or correspondence or communications  related thereto, if it is
in writing, or a complete written summary thereof, if it is not in writing.  For
purposes of this Agreement,


                                      -25-


"Takeover  Proposal"  means any offer or  proposal  for,  or any  indication  of
interest in, a merger or other business  combination  involving Target or any of
its subsidiaries or the acquisition of any significant  equity interest in, or a
significant  portion of the assets of, Target or any of its subsidiaries,  other
than the transactions  contemplated by this Agreement.  Neither the execution by
Target of the Asset Purchase  Agreement nor the  consummation of the Pre-Closing
Asset  Transaction  nor the  disclosure of information  regarding  Target to the
Acquiror  under the Asset Purchase  Agreement  shall be deemed to be a breach of
this Section 4.2.
    

                                      -26-



                                    ARTICLE V

                             ADDITIONAL AGREEMENTS
                             ---------------------

         5.1 Proxy Statement.  As promptly as practicable after the execution of
this  Agreement,  Target and Acquiror shall prepare,  and Target shall file with
the SEC,  preliminary proxy materials relating to the approval of the Merger and
the  transactions  contemplated  hereby by the  shareholders  of Target  and, as
promptly as practicable following receipt of SEC comments thereon,  Target shall
file  with  the SEC  definitive  proxy  materials  which  comply  in  form  with
applicable SEC requirements. Target will notify Acquiror promptly of the receipt
of any  comments  from the SEC or its staff and of any request by the SEC or its
staff or any other  government  officials for  amendments or  supplements to the
Proxy  Statement  or any other  filing or for  additional  information  and will
supply Acquiror with copies of all  correspondence  between Target or any of its
representatives,  on the one  hand,  and the  SEC,  or its  staff  or any  other
government officials,  on the other hand, with respect to the Proxy Statement or
other  filing.  The Proxy  Statement  and the other  filings shall comply in all
material  respects with all applicable  requirements of law.  Whenever any event
occurs that is required to be set forth in an  amendment  or  supplement  to the
Proxy  Statement or any other filing,  Target shall promptly  inform Acquiror of
such  occurrence  and cooperate in filing with the SEC or its staff or any other
government  officials,  and/or mailing to shareholders of Target, such amendment
or  supplement.  Subject to the  provisions of Section 4.2, the Proxy  Statement
shall include the recommendation of the Board of Directors of Target in favor of
the  Merger;  provided  that such  recommendation  may not be included or may be
withdrawn if previously included if Target's Board of Directors believes in good
faith that a Superior  Proposal has been made and,  upon  written  advice of its
outside legal counsel,  shall determine that to include such  recommendation  or
not withdraw such  recommendation  if  previously  included  would  constitute a
breach of the Board's fiduciary duty under applicable law.

         5.2  Meeting of  Shareholders.  Target  shall  promptly  after the date
hereof take all action  necessary  in  accordance  with  California  Law and its
Articles of Incorporation and Bylaws to convene the Target Shareholders  Meeting
within 45 days of the filing of the  definitive  proxy  materials.  Target shall
consult with Acquiror regarding the date of the Target Shareholders  Meeting and
use all reasonable efforts and shall not postpone or adjourn (other than for the
absence of a quorum)  the Target  Shareholders  Meeting  without  the consent of
Acquiror.  Subject to Section 5.1,  Target shall use its best efforts to solicit
from  shareholders  of Target  proxies in favor of the Merger and shall take all
other  action   necessary  or  advisable  to  secure  the  vote  or  consent  of
shareholders required to effect the Merger.

         5.3  Access to Information.

                  a. Target shall afford Acquiror and its  accountants,  counsel
and other  representatives,  upon reasonable  advance notice,  reasonable access
during normal  business  hours during the period prior to the Effective  Time to
(i)  all  of  Target's  and  its  subsidiaries'  properties,  books,  contracts,
commitments and records, and (ii) all other information concerning the business,
properties  and  personnel  of  Target  and its  subsidiaries  as  Acquiror  may
reasonably  request. 


                                      -27-


Target  agrees to provide to  Acquiror  and its  accountants,  counsel and other
representatives copies of internal financial statements promptly upon request.
                                    
                  b. Subject to compliance  with  applicable  law, from the date
hereof until the Effective  Time,  each of Acquiror and Target shall confer on a
regular and frequent basis with one or more  representatives  of the other party
to report  operational  matters of materiality and the general status of ongoing
operations.

                  c. No information or knowledge  obtained in any  investigation
pursuant  to  this  Section  5.3  shall  affect  or  be  deemed  to  modify  any
representation or warranty contained herein or the conditions to the obligations
of the parties to consummate the Merger.

         5.4 Confidentiality.  The parties acknowledge that each of Acquiror and
Target have previously  executed a non-disclosure  agreement dated May 29, 1996,
as amended on June 6, 1996 (as amended, the "Confidentiality Agreement"),  which
Confidentiality  Agreement shall continue in full force and effect in accordance
with its terms.

         5.5 Public  Disclosure.  Unless otherwise  permitted by this Agreement,
Acquiror  and Target  shall  consult  with each other  before  issuing any press
release or otherwise  making any public statement or making any other public (or
non-confidential)  disclosure  (whether  or  not  in  response  to  an  inquiry)
regarding the terms of this Agreement and the transactions  contemplated hereby,
and neither  shall issue any such press  release or make any such  statement  or
disclosure  without the prior approval of the other (which approval shall not be
unreasonably  withheld),  except  as may be  required  by law or by  obligations
pursuant to any listing agreement with any national  securities exchange or with
the NASD.

         5.6  Consents; Cooperation.

                  a. Each of Acquiror  and Target  shall  promptly  apply for or
otherwise  seek,  and use its  reasonable  efforts to obtain,  all  consents and
approvals  required  to be obtained  by it for the  consummation  of the Merger,
including  those  required  under HSR, and shall use its  reasonable  efforts to
obtain all necessary  consents,  waivers and approvals under any of its material
contracts in connection with the Merger for the assignment thereof or otherwise.
The parties hereto will consult and cooperate with one another,  and consider in
good  faith  the  views  of  one  another,  in  connection  with  any  analyses,
appearances, presentations, memoranda, briefs, arguments, opinions and proposals
made or  submitted  by or on  behalf  of any party  hereto  in  connection  with
proceedings  under or relating to HSR or any other federal or state antitrust or
fair trade law.

                  b.  Each of  Acquiror  and  Target  shall  use all  reasonable
efforts  to  resolve  such  objections,  if  any,  as  may  be  asserted  by any
Governmental  Entity  with  respect  to the  transactions  contemplated  by this
Agreement  under HSR, the Sherman Act, as amended,  the Clayton Act, as amended,
the Federal Trade  Commission Act, as amended,  and any other Federal,  state or
foreign  statutes,  rules,  regulations,  orders or decrees that are designed to
prohibit,  restrict  or  regulate  actions  having  the  purpose  or  effect  of
monopolization  or  restraint  of trade  (collectively, 


                                      -28-


"Antitrust  Laws"). In connection  therewith,  if any administrative or judicial
action or proceeding is instituted (or threatened to be instituted)  challenging
any  transaction  contemplated  by this  Agreement as violative of any Antitrust
Law, each of Acquiror and Target shall cooperate and use all reasonable  efforts
vigorously  to  contest  and resist any such  action or  proceeding  and to have
vacated,  lifted,  reversed, or overturned any decree,  judgment,  injunction or
other order, whether temporary, preliminary or permanent (each an "Order"), that
is in effect and that  prohibits,  prevents,  or restricts  consummation  of the
Merger or any such other  transactions,  unless by mutual agreement Acquiror and
Target  decide  that  litigation  is not in  their  respective  best  interests.
Notwithstanding  the provisions of the  immediately  preceding  sentence,  it is
expressly  understood and agreed that neither  Acquiror nor Target shall have an
obligation  to  litigate  or contest any  administrative  or judicial  action or
proceeding  or any Order beyond  November 30, 1996.  Each of Acquiror and Target
shall use all reasonable efforts to take such action as may be required to cause
the expiration of the notice periods under the HSR or other  Antitrust Laws with
respect to such transactions as promptly as possible after the execution of this
Agreement.

                  c. Notwithstanding  anything to the contrary in Section 5.6(a)
or (b),  (i) neither  Acquiror nor any of it  subsidiaries  shall be required to
divest any of their respective  businesses,  product lines or assets, or to take
or  agree to take any  other  action  or  agree  to any  limitation  that  could
reasonably  be  expected  to have a Material  Adverse  Effect on  Acquiror or of
Acquiror  combined with the Surviving  Corporation  after the Effective  Time or
(ii)  neither  Target nor its  subsidiaries  shall be  required to divest any of
their  respective  businesses,  product lines or assets,  or to take or agree to
take any other  action  or agree to any  limitation  that  could  reasonably  be
expected to have a Material Adverse Effect on Target.

         5.7  Other Operational Covenants.

                  a. Target agrees to use  reasonable  efforts to ensure that on
the  Closing  Date its  cash and cash  equivalents  balance  equals  or  exceeds
$3,500,000.

                  b. Target  agrees to use in the period prior to the  Effective
Time reasonable  efforts to meet the product  development  schedule for its MICA
products  that  has  been  previously  disclosed  to  Acquiror.   In  connection
therewith,  Target  shall  promptly  notify  Acquiror in the event  Target shall
experience  any material  delays in the product  development  schedule or if any
material  issues with respect to the technology  used in the MICA products shall
arise prior to the Effective Time.

         5.8 Legal Requirements.  Each of Acquiror,  Merger Sub and Target will,
and will cause their  respective  subsidiaries  to, take all reasonable  actions
necessary to comply promptly with all legal requirements which may be imposed on
them with respect to the consummation of the  transactions  contemplated by this
Agreement and will promptly cooperate with and furnish  information to any party
hereto  necessary in  connection  with any such  requirements  imposed upon such
other party in connection with the consummation of the transactions contemplated
by this Agreement and will take all reasonable  actions necessary to obtain (and
will  cooperate  with the  other  parties  hereto  in  obtaining)  any  consent,
approval, order or authorization of, or any registration,  declaration or filing
with, any Governmental  Entity or other person,  required to be 



                                      -29-


obtained or made in  connection  with the taking of any action  contemplated  by
this  Agreement.  Each of Acquiror and Target further agrees to notify the other
promptly  of the  receipt of any  comments  from any  government  officials  for
amendments or supplements to any filing or for additional  information  and will
supply the other with copies of all  correspondence  between such company or any
of its representatives,  on the one hand, and the government  officials,  on the
other  hand,  with  respect to such  filing.  All  filings  shall  comply in all
material  respects with all applicable  requirements of law.  Whenever any event
occurs which is required to be set forth in an amendment  or  supplement  to any
such filing,  Acquiror or Target,  as the case may be, shall promptly inform the
other of such occurrence and cooperate in filing with the government officials.

         5.9  Employee Benefit Plans.

                  a. Each option  outstanding  at the  Effective  Time under the
Target  Stock Option Plans  shall,  to the extent  exercisable  at that time for
vested shares of Target Common Stock  (including any shares which, in accordance
with the  provisions  of those  Plans or the  Employment  Agreements  listed  in
Schedule 2.14, vest on an accelerated  basis in connection with the Merger),  be
cancelled,  and the holder of each such  cancelled  option  shall be entitled to
receive  a cash sum per  vested  share of Target  Common  Stock  subject  to the
cancelled option equal to the Merger  Consideration  payable per share of Target
Common Stock less the exercise  price per share of Target Common Stock in effect
under  that  option  immediately  prior  to  the  Effective  Time.  Each  option
outstanding  at the  Effective  Time  under  the 1995  Plan  which is held by an
employee  of  Target  who  shall  continue  his or her  employment  with  Target
following  the  Effective  Time shall,  to the extent that option is not at such
time  exercisable  for  vested  shares of Target  Common  Stock,  be  assumed by
Acquiror  and  converted  into an option to purchase  shares of Acquiror  Common
Stock in accordance  with the procedure set forth in Section 5.9(b) below.  Each
option outstanding at the Effective Time under the 1995 Plan which is held by an
employee of Target who shall transfer employment directly from Target to Telebit
(Newco) Inc.  following the Effective  Time shall,  to the extent that option is
not at such time  exercisable  for  vested  shares of Target  Common  Stock,  be
treated in the manner  determined by Telebit  (Newco) Inc., and Acquiror  shall,
upon written  receipt of notice from  Telebit  (Newco) Inc. as to such manner of
treatment,  take all  reasonable  ministerial  action  necessary  to effect  any
required  allocation  of  outstanding  options under the 1995 Plan between those
options  assumed by Acquiror  and any options to be assumed by Newco.  All other
options  outstanding  at the Effective Time under the Target Option Plans shall,
to the extent not  exercisable  for vested shares of Target Common Stock at that
time,  terminate and cease to be outstanding at the Effective Time and shall not
be assumed by either  Acquiror or Newco.  Schedule  5.9 hereto sets forth a true
and  complete  list as of the date  hereof  of (i) all  holders  of  outstanding
options  under the Target Stock Option  Plans,  specifically  identifying  those
holders  whose  employment  with  Target is  presently  anticipated  to continue
following the Effective  Time, (ii) the number of shares of Target capital stock
subject to each such option,  (iii) the  exercise or vesting  schedule in effect
for that option,  (iv) the  exercise  price  payable per share of Target  Common
Stock and (v) the term of each such option.  On the Closing Date,  Target shall,
in cooperation with Acquiror, deliver to Acquiror an updated Schedule 5.9 hereto
current as of such date.


                                      -30-


                  b. Each outstanding  option under the 1995 Plan which is to be
assumed by Acquiror  under Section 5.9(a) shall continue to have, and be subject
to, the same terms and conditions in effect for that option immediately prior to
the Effective Time,  except for the following  adjustments to reflect the Merger
Consideration:

                           (i) the  number of whole  shares of  Acquiror  Common
         Stock  subject to that option shall be determined  by  multiplying  the
         number of unvested shares of Target Common Stock subject to that option
         immediately  prior to the Effective Time by a fraction the numerator of
         which is the Merger  Consideration  payable per share of Target  Common
         Stock  and the  denominator  of which  is the  average  of the  closing
         selling prices per share of Acquiror  Common Stock for the five trading
         days  ending  with the second  trading day  immediately  preceding  the
         Closing Date and then  rounding  that number down to the nearest  whole
         number of shares of Acquiror Common Stock, and

                           (ii) the per share  exercise  price for the shares of
         Acquiror  Common  Stock  issuable  upon  exercise of each such  assumed
         option shall be determined by multiplying  the exercise price per share
         of Target Common Stock at which such option is exercisable  immediately
         prior to the  Effective  Time by a fraction  the  numerator of which is
         [the average of the closing selling prices per share of Acquiror Common
         Stock for the five  trading  days  ending  with the second  trading day
         immediately  preceding the Closing Date and the denominator of which is
         the Merger  Consideration  payable per share of Target Common Stock and
         then rounding that dollar amount up to the nearest whole cent.

                  Consistent with the terms of the Target Stock Option Plans and
the documents  governing the outstanding  options under those Plans,  the Merger
shall not result in the  termination of any  outstanding  options under the 1995
Plan  which are so assumed by  Acquiror  or  accelerate  the  exercisability  or
vesting of those  assumed  options or the shares of Acquiror  Common Stock which
will be subject to those options upon the  Acquiror's  assumption of the options
in the Merger. It is the intention of the parties that the options so assumed by
Acquiror  qualify  following  the Effective  Time as incentive  stock options as
defined  in Section  422 of the Code to the extent  such  options  qualified  as
incentive  stock options prior to the  Effective  Time.  Within 10 business days
after the Effective  Time,  Acquiror will issue to each person who,  immediately
prior to the Effective Time is a holder of an outstanding  option under the 1995
Plan  which is to be  assumed  by  Acquiror  hereunder  a  document  in form and
substance  satisfactory  to Target  evidencing the foregoing  assumption of such
option by Acquiror.

                  c. Outstanding  purchase rights under the Target ESPP shall be
exercised  upon the earlier of (i) the next  scheduled  purchase  date under the
Target  ESPP  or  (ii)  immediately  prior  to  the  Effective  Time,  and  each
participant  in the Target  ESPP shall  accordingly  be issued  shares of Target
Common  Stock  at that  time  which  shall  automatically  be  converted  at the
Effective  Time into the right to receive the Merger  Consideration  payable per
share of Target Common Stock in the Merger. The Target ESPP shall terminate with
such exercise  date,  and no purchase  rights shall be  subsequently  granted or
exercised  under the Target  ESPP.  Target  employees  who meet the  eligibility
requirements  for  participation  in the Acquiror  Employee  Stock



                                      -31-


Purchase Plan shall be eligible to begin payroll  deductions  under that plan as
of the start date of the first  offering  period  thereunder  beginning at least
thirty (30) days after the Effective Time.

         5.10 Form S-8.  Acquiror agrees to file, no later than thirty (30) days
after the Closing,  a registration  statement on Form S-8 covering the shares of
Acquiror  Common Stock issuable  pursuant to outstanding  options under the 1995
Plan assumed by Acquiror. Target shall cooperate with and assist Acquiror in the
preparation of such registration statement.

         5.11  Option  Agreement.   Concurrently  with  the  execution  of  this
Agreement,  Target shall deliver to Acquiror an executed Option Agreement in the
form of Exhibit C attached hereto.

         5.12 Nasdaq  Quotation.  Target  agrees to continue  the  quotation  of
Target  Common  Stock  on the  Nasdaq  National  Market  during  the term of the
Agreement  so  that,  to the  extent  necessary,  appraisal  rights  will not be
available  to  shareholders  of  Target  under  Sections  1300  et  seq.  of the
California Law.

         5.13 Indemnification.

                  a. After the Effective Time, Acquiror will, and will cause the
Surviving  Corporation  to,  indemnify  and hold harmless the present and former
officers, directors,  employees and agents of Target (the "Indemnified Parties")
in respect of acts or omissions  occurring on or prior to the Effective  Time to
the extent  permitted by law and to the extent provided under Target's  Articles
of  Incorporation  and  Bylaws  or any  indemnification  agreement  with  Target
officers and directors to which Target is a party, in each case in effect on the
date  hereof;  provided  that  such  indemnification  shall  be  subject  to any
limitation imposed from time to time under applicable law. Without limitation of
the foregoing, in the event any such Indemnified Party is or becomes involved in
any capacity in any action,  proceeding or  investigation in connection with any
matter  relating  to this  Agreement  or the  transactions  contemplated  hereby
occurring on or prior to the Effective Time,  Acquiror shall, or shall cause the
Surviving  Corporation to, pay as incurred such Indemnified  Party's  reasonable
legal  and  other  expenses   (including  the  cost  of  any  investigation  and
preparation) incurred in connection therewith.

                  b. For four years  after the  Effective  Time,  Acquiror  will
either  (i) at all times  maintain  at least  $500,000,000  in cash,  marketable
securities  and  unrestricted  lines of credit to be available to indemnify  the
Indemnified  Parties in accordance  with Section  5.15(a) above (but such amount
shall not be  construed as a limitation  of any such  indemnification),  or (ii)
cause the Surviving Corporation to use its best efforts to provide officers' and
directors'  liability  insurance in respect of acts or omissions occurring on or
prior to the  Effective  Time  covering  each such person  currently  covered by
Target's   officers'  and  directors'   liability   insurance  policy  on  terms
substantially  similar  to those of such  policy in  effect on the date  hereof,
provided that in satisfying  its obligation  under this Section,  Acquiror shall
not be obligated to cause the Surviving Corporation to pay premiums in excess of
150% of the amount per annum  Target  paid in its last full fiscal  year,  which
amount has been  disclosed  to Acquiror,  and if the  Surviving  Corporation  is
unable to obtain the insurance required by this Section 5.15, it shall obtain as
much  comparable  insurance  as  possible  for an annual  premium  equal to such

Exhibits or Schedules, such reference shall be to an Exhibit or Schedule to this
Agreement  unless  otherwise  indicated.  The words  "include,"  "includes"  and
"including"  when used herein shall be deemed in each case to be followed by the

mean that the  information  referred to has been made  available if requested by
the party to whom such  information  is to be made  available.  The phrases "the
date of this Agreement",  "the date hereof", and terms of similar import, unless
the context otherwise  requires,  shall be deemed to refer to July 21, 1996. The
table of contents and headings  contained in this  Agreement  are for  reference
purposes only and shall not affect in any way the meaning or  interpretation  of
this Agreement.  All references to "dollars" and "cents" in this Agreement shall

         8.4  Counterparts.  This  Agreement  may be  executed  in  one or  more
counterparts,  all of which shall be considered  one and the same  agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other  parties,  it being  understood  that all
parties need not sign the same counterpart.

         8.5  Entire  Agreement;  Nonassignability;  Parties in  Interest.  This
Agreement and the documents and  instruments and other  agreements  specifically
referred to herein or delivered  pursuant  hereto,  including the Exhibits,  the
Schedules,  including the Target  Disclosure  Schedule (a) constitute the entire
agreement  among the  parties  with  respect to the  subject  matter  hereof and
supersede all prior agreements and understandings,  both written and oral, among
the  parties  with  respect  to  the  subject  matter  hereof,  except  for  the
Confidentiality  Agreement,  which shall continue in full force and effect,  and
shall survive any  termination of this  Agreement or the Closing,  in accordance
with its terms;  (b) are not intended to confer upon any other person any rights

         8.6 Severability. In the event that any provision of this Agreement, or
the  application  thereof,  becomes  or is  declared  by a  court  of  competent
jurisdiction  to be  illegal,  void  or  unenforceable,  the  remainder  of this
Agreement  will  continue in full force and effect and the  application  of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such  void or  unenforceable  provision  of  this  Agreement  with a  valid  and
enforceable  provision that will 


                                      -42-


achieve,  to the extent possible,  the economic,  business and other purposes of
such void or unenforceable provision.

         8.7 Remedies  Cumulative.  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 or equity
upon such party, and the exercise by a party of any one remedy will not preclude
the exercise of any other remedy.

         8.8 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws that might otherwise govern under applicable principles
of  conflicts of law.  Each of the parties  hereto  irrevocably  consents to the
exclusive  jurisdiction  of any court located  within the State of California in
connection  with any matter  based upon or arising out of this  Agreement or the
matters contemplated herein,  agrees that process may be served upon them in any
manner  authorized by the laws of the State of  California  for such persons and
waives  and  covenants  not to assert or plead any  objection  which  they might
otherwise have to such jurisdiction and such process.

         8.9 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation, preparation and execution of this
Agreement and, therefore, waive the application of any law, regulation,  holding
or rule of  construction  providing  that  ambiguities  in an agreement or other
document  will be  construed  against  the  party  drafting  such  agreement  or
document.

                                   AGREEMENTS
                                   ----------

                  The parties hereto hereby agree as follows:

                  1. Merger Sub shall be merged with and into Target, and Target
shall be the surviving corporation.

                  2.  The  Merger  shall  become  effective  at such  time  (the
"Effective  Time" of the  Merger) as this  Merger  Agreement  and the  officers'
certificates  of Merger Sub and Target are filed with the  Secretary of State of
the State of California pursuant to Section 1103 of the Corporations Code of the
State of California.

                  3. At the  Effective  Time of the  Merger  (i) all  shares  of
Target Common Stock that are owned  directly or indirectly by Target,  Acquiror,
Merger  Sub or any other  subsidiary  of  Acquiror  shall be  cancelled,  and no
securities  of Acquiror or other  consideration  shall be  delivered in exchange
therefor,  and (ii) each of the issued and  outstanding  shares of Target Common
Stock shall be canceled and extinguished and be converted automatically into the
right to receive thirteen dollars and thirty-five cents ($13.35).

                  4. The conversion of Target Common Stock into cash as provided
by this Merger Agreement shall occur  automatically at the Effective Time of the
Merger without action by the holders thereof. Each holder of Target Common Stock
shall thereupon be entitled to receive  thirteen  dollars and thirty-five  cents
($13.35) per share, in accordance with the following procedures:

                         a.  Promptly  after the  Effective  Time of the Merger,
Acquiror  shall deliver to the Exchange  Agent (as defined in Section 1.7 of the
Agreement and Plan of Reorganization) for exchange in accordance with Section 3,
through such  reasonable  procedures  as Acquiror  may adopt,  cash in an amount
sufficient  to  permit  payment  (i)  pursuant  to  Section  3 in  exchange  for
outstanding  shares of Target Common Stock outstanding  immediately prior to the
Effective  Time of the Merger and (ii)  pursuant to Section 5.9 of the Agreement
and Plan of Reorganization  upon  cancellation of outstanding  vested options to
acquire shares of Target Common Stock.

                         b. Promptly after the Effective Time of the Merger, the
Exchange  Agent  shall  mail  to each  holder  of  record  of a  certificate  or
certificates  which  immediately  prior  to the  Effective  Time  of the  Merger
represented  outstanding  shares of  Target  Common  Stock,  whose  shares  were
converted  into the right to receive cash pursuant to Section 3, (i) a letter of
transmittal  (which shall specify that delivery  shall be effected,  and risk of
loss and  title  to the  certificates  shall  pass,  only  upon  receipt  of the
certificates by the Exchange Agent and shall be in such form and have such other
provisions as Acquiror may reasonably  specify) and (ii) instructions for use in
effecting the surrender of the certificates in exchange for cash. Upon 



                                      A-2


surrender of a certificate  for  cancellation  to the Exchange  Agent or to such
other agent or agents as may be appointed by Acquiror, together with such letter
of transmittal,  duly executed, the holder of such certificate shall be entitled
to receive in exchange  therefor cash representing the payment which such holder
has the right to receive  pursuant to Section 3 hereof,  and the  certificate so
surrendered shall forthwith be canceled. In the event of a transfer of ownership
of Target  Common  Stock  which is not  registered  in the  transfer  records of
Target, payment may be made to a transferee if the certificate representing such
Target  Common Stock is presented to Acquiror and  accompanied  by all documents
required  to  evidence  and  effect  such  transfer  and to  evidence  that  any
applicable   stock  transfer  taxes  have  been  paid.   Until   surrendered  as
contemplated  by this  Section 4, each  certificate  shall be deemed at any time
after the  Effective  Time of Merger to represent the right to receive upon such
surrender  an amount in cash as  provided  by  Section 3 and the  provisions  of
applicable law.

                         c. All cash paid upon the  surrender  for  exchange  of
Target Common Stock in accordance  with the terms hereof shall be deemed to have
been paid in full  satisfaction  of all rights  pertaining to such Target Common
Stock. There shall be no further registration of transfers on the stock transfer
books  of the  Surviving  Corporation  of the  Target  Common  Stock  that  were
outstanding immediately prior to the Effective Time of the Merger. If, after the
Effective  Time of the Merger,  certificates  are  presented to Acquiror for any
reason, they shall be cancelled and exchanged as provided in this Section 4.

                  5. At the Effective Time of the Merger, the separate existence
of Merger Sub shall cease, and Target shall succeed,  without other transfer, to
all of the rights and  properties  of Merger Sub and shall be subject to all the
debts  and  liabilities  thereof  in the same  manner as if  Target  had  itself
incurred  them.  All rights of creditors and all liens upon the property of each
corporation  shall be  preserved  unimpaired,  provided  that  such  liens  upon
property  of Merger  Sub  shall be  limited  to the  property  affected  thereby
immediately prior to the Effective Time of the Merger.

                  6. At the Effective  Time of the Merger,  each share of Merger
Sub stock that is  outstanding  immediately  prior to the Effective  Time of the
Merger  shall be  converted  into one  share of  common  stock of the  Surviving
Corporation.

                  7. (a) The Amended and Restated  Articles of  Incorporation as
set forth on  Schedule 1 to this  Agreement  of Merger  shall be the Amended and
Restated Articles of Incorporation of Target as the surviving  corporation after
the Merger unless thereafter amended.

                         a. The Bylaws of Merger Sub in effect immediately prior
to the Effective  Time shall be the Bylaws of the Surviving  Corporation  unless
and until  amended or repealed as provided by  applicable  law,  the Articles of
Incorporation of the Surviving Corporation and such Bylaws.

                         b. The directors of Merger Sub immediately prior to the
Effective Time shall be the initial directors of the Surviving Corporation.  The
officers  of Merger Sub  immediately  prior to the  Effective  Time shall be the
initial officers of the Surviving Corporation.

                                      A-3

                  8. (a)  Notwithstanding  the approval of this Merger Agreement
by the  shareholders  of Target and Merger  Sub,  this Merger  Agreement  may be
terminated  at any time  prior to the  Effective  Time of the  Merger  by mutual
agreement of the Boards of Directors of Acquiror, Target and Merger Sub.

                         a.   Notwithstanding   the   approval  of  this  Merger
Agreement by the  shareholders  of Target and Merger Sub, this Merger  Agreement
shall  terminate  forthwith  in  the  event  that  the  Agreement  and  Plan  of
Reorganization shall be terminated as therein provided.

                         b. In the  event  of the  termination  of  this  Merger
Agreement as provided above,  this Merger  Agreement shall forthwith become void
and there shall be no liability on the part of Target, Acquiror or Merger Sub or
their  respective  officers or  directors,  except as otherwise  provided in the
Agreement and Plan of Reorganization.

                         c. This Merger  Agreement  may be signed in one or more
counterparts,  each of which shall be deemed an original  and all of which shall
constitute one agreement.

                         d. This Merger  Agreement may be amended by the parties
hereto any time before or after approval  hereof by the  shareholders  of Target
and Merger Sub, but, after such approval,  no amendments  shall be made which by
law require the further  approval of such  shareholders  without  obtaining such
approval.  This Merger  Agreement may not be amended  except by an instrument in
writing signed on behalf of each of the parties hereto.

                                      A-4

                  IN WITNESS  WHEREOF,  the parties  have  executed  this Merger
Agreement as of the date first written above.

                               TELEBIT CORPORATION

                                VOTING AGREEMENT


         THIS VOTING AGREEMENT (this "Agreement") is made and entered into as of
July  21,  1996,   between  Cisco  Systems,   Inc.,  a  California   corporation
("Acquiror"),   and  the  undersigned  shareholder  ("Shareholder")  of  Telebit
Corporation, a California corporation ("Target").

                                    RECITALS

         A.   Pursuant  to  an  Agreement  and  Plan  of   Reorganization   (the
"Reorganization  Agreement"),  dated as of July 21, 1996 by and among  Acquiror,
Cobra  Acquisition  Corporation,  a California  corporation  ("Merger  Sub") and
wholly owned subsidiary of Acquiror,  and Target, Merger Sub is merging with and
into Target (the  "Merger")  and Target,  as the  surviving  corporation  of the
Merger, will thereby become a wholly owned subsidiary of Acquiror;

         B.  Pursuant  to  Section  5.7 of the  Reorganization  Agreement  and a
written  request from  Acquiror,  in order to induce  Acquiror to enter into the
Reorganization  Agreement,  Target has agreed to use its best efforts to solicit
the proxy of certain  significant  shareholders of Target on behalf of Acquiror,
and to cause certain  significant  shareholders of Target to execute and deliver
to Acquiror Voting Agreements; and

         C. The  Shareholder is the  beneficial  owner (as defined in Rule 13d-3
under the Securities  Exchange Act of 1934, as amended (the "Exchange  Act")) of
such number of shares of the  outstanding  Common Stock, no par value per share,
of Target as is indicated on the final page of this Agreement (the "Shares").


                                      B-1



         NOW, THEREFORE, the parties agree as follows:

         1.  Agreement to Retain Shares.

                  1.1  Transfer  and  Encumbrance.  Shareholder  agrees  not  to
transfer  (except  as  may be  specifically  required  by  court  order),  sell,
exchange,  pledge  (except  in  connection  with a bona fide  loan  transaction,
provided  that any pledgee  agrees not to transfer,  sell,  exchange,  pledge or
otherwise  dispose of or  encumber  the Shares or any New Shares (as  defined in
Section  1.2)  prior to the  Expiration  Date and to be subject to the Proxy (as
defined in Section 3)) or otherwise dispose of or encumber the Shares or any New
Shares, or to make any offer or agreement relating thereto, at any time prior to
the Expiration Date. As used herein,  the term "Expiration  Date" shall mean the
earlier to occur of (i) such date and time as the Merger shall become  effective
in accordance with the terms and provisions of the Reorganization Agreement, and
(ii) six months after the date of  termination of the  Reorganization  Agreement
(unless  the  Reorganization   Agreement  shall  have  been  terminated  in  the
circumstances contemplated by any of Sections 7.1(a), (d) or (f) (i) thereof, in
which case, this six-month extension shall not be effective or applicable).

                  1.2 New Shares.  Shareholder agrees that any shares of capital
stock of Target that Shareholder  purchases or with respect to which Shareholder
otherwise  acquires  beneficial  ownership  after the date of this Agreement and
prior to the  Expiration  Date ("New  Shares") shall be subject to the terms and
conditions of this Agreement to the same extent as if they constituted Shares.

         2. Agreement to Vote Shares.  At every meeting of the  shareholders  of
Target  called with respect to any of the  following,  and at every  adjournment
thereof,  and on every action or approval by written consent of the shareholders
of Target  with  respect  to any of the  following,  Shareholder  shall vote the
Shares  and any New  Shares  (i) in  favor  of  approval  of the  Reorganization
Agreement and the Merger and the transactions contemplated by the Asset Purchase
Agreement dated of even date herewith (the "Asset Purchase  Agreement")  between
Target and Telebit (Newco) Corporation (the "Asset  Transaction") and any matter
that  could  reasonably  be  expected  to  facilitate  the  Merger and the Asset
Transaction and (ii) against any proposal for any recapitalization, merger, sale
of assets or other  business  combination  (other  than the Merger and the Asset
Transaction)  between Target and any person or entity other than Acquiror or any
other  action or  agreement  that  would  result  in a breach  of any  covenant,
representation  or warranty or any other obligation or agreement of Target under
the  Reorganization  Agreement or the Asset Transaction or which could result in
any of the conditions to Target's obligations under the Reorganization Agreement
or the Asset Transaction not being fulfilled. This Agreement is intended to bind
Shareholder as a shareholder of Target only with respect to the specific matters
set forth herein.

         3.  Irrevocable   Proxy.   Concurrently  with  the  execution  of  this
Agreement,  Shareholder  agrees  to  deliver  to  Acquiror  a proxy  in the form
attached  hereto as Exhibit A (the  "Proxy"),  which shall be irrevocable to the
extent  provided  in Section  705 of the  California  General  Corporation  Law,
covering the total number of Shares and New Shares  beneficially 


                                      B-2


owned or as to which  beneficial  ownership is acquired (as such term is defined
in Rule 13d-3 under the Exchange Act) by Shareholder set forth therein.

         4.   Representations,   Warranties   and   Covenants  of   Shareholder.
Shareholder  hereby   represents,   warrants  and  covenants  to  Acquiror  that
Shareholder (i) is the beneficial owner of the Shares, which at the date of this
Agreement and at all times up until the  Expiration  Date will be free and clear
of any liens,  claims,  options,  charges or other  encumbrances;  (ii) does not
beneficially  own any  shares of capital  stock of Target  other than the Shares
(excluding  shares  as  to  which  Shareholder  currently  disclaims  beneficial
ownership  in  accordance  with  applicable  law);  and (iii) has full power and
authority to make,  enter into and carry out the terms of this Agreement and the
Proxy.

         5. Additional  Documents.  Shareholder  hereby  covenants and agrees to
execute  and deliver  any  additional  documents  necessary,  in the  reasonable
opinion of Acquiror, to carry out the purpose and intent of this Agreement.

         6. Consent and Waiver. Shareholder hereby gives any consents or waivers
that are reasonably  required for the consummation of the Merger under the terms
of any  agreement  to which  Shareholder  is a party or  pursuant  to any rights
Shareholder may have.

         7.  Termination.  This Agreement and the Proxy  delivered in connection
herewith  shall  terminate  and shall have no further  force or effect as of the
Expiration Date.

         8. Miscellaneous.

                  8.1  Severability.   If  any  term,  provision,   covenant  or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid,  void or  unenforceable,  then the remainder of the terms,  provisions,
covenants  and  restrictions  of this  Agreement  shall remain in full force and
effect and shall in no way be affected, impaired or invalidated.

                  8.2 Binding Effect and  Assignment.  This Agreement and all of
the  provisions  hereof  shall be binding  upon and inure to the  benefit of the
parties  hereto and their  respective  successors  and permitted  assigns,  but,
except as otherwise specifically provided herein, neither this Agreement nor any
of the rights, interests or obligations of the parties hereto may be assigned by
either of the parties without the prior written consent of the other.

                  8.3  Amendment  and  Modification.  This  Agreement may not be
modified,  amended, altered or supplemented except by the execution and delivery
of a written agreement executed by the parties hereto.

                  8.4  Specific  Performance;  Injunctive  Relief.  The  parties
hereto  acknowledge that Acquiror will be irreparably harmed and that there will
be no  adequate  remedy  at law  for a  violation  of any  of the  covenants  or
agreements of  Shareholder  set forth herein.  Therefore,  it is agreed that, in
addition to any other  remedies  that may be available to Acquiror upon any such


                                      B-3


violation,  Acquiror  shall  have  the  right  to  enforce  such  covenants  and
agreements  by  specific  performance,  injunctive  relief or by any other means
available to Acquiror at law or in equity.

                             STOCK OPTION AGREEMENT



                  THIS STOCK OPTION  AGREEMENT  (the  "Agreement"),  dated as of
July 21, 1996,  by and between  Cisco  Systems,  Inc., a California  corporation
("Acquiror"), and Telebit Corporation, a California corporation ("Target").

                  WHEREAS,  concurrently with the execution and delivery of this
Agreement,  Target,  Acquiror and Cobra  Acquisition  Corporation,  a California
corporation  ("Merger  Sub"),  are  entering  into  an  Agreement  and  Plan  of
Reorganization,  dated as of the date hereof (the  "Reorganization  Agreement"),
which  provides  that,  among  other  things,  upon the terms and subject to the
conditions  thereof,  Merger  Sub  will be  merged  with and  into  Target  (the
"Merger"), with Target continuing as the surviving corporation; and

                  WHEREAS,   as  a  condition   and   inducement  to  Acquiror's
willingness to enter into the  Reorganization  Agreement,  Acquiror has required
that Target agree, and Target has so agreed, to grant to Acquiror an option with
respect to certain  shares of Target's  common stock on the terms and subject to
the conditions set forth herein.

                  NOW,  THEREFORE,  in consideration of the foregoing and of the
mutual  covenants  and  agreements  set forth  herein and in the  Reorganization
Agreement, the parties hereto agree as follows:


                  9.  Grant  of  Option.   Target  hereby  grants   Acquiror  an
irrevocable option (the "Target Option") to purchase up to 2,071,000 shares (the
"Target Shares") of common stock, no par value per share, of Target (the "Target
Common Stock") in the manner set forth below at a price (the  "Exercise  Price")
of thirteen dollars and thirty-five cents ($13.35) per Target Share,  payable in
cash; provided,  however, that in the event either (i) Acquiror and Target shall
at any  time  following  the date  hereof  agree to an  increase  in the  Merger
Consideration  price per Target Share payable in the Merger (as evidenced by the
execution of a written definitive agreement providing for such increased price),
or (ii) Acquiror shall at any time  following the date hereof  commence a tender
or exchange offer for Target Shares at a price per Target Share greater than the
Merger  Consideration  (as evidenced by the filing of a Schedule  14D-1 with the
Securities and Exchange  Commission),  then the Exercise Price  hereunder  shall
automatically  be  increased to such higher  agreed or offered  price per Target
Share.  Capitalized  terms used  herein but not  defined  herein  shall have the
meanings set forth in the Reorganization Agreement.

                  10. Exercise of Option.  The Target Option may be exercised by
Acquiror,  in  whole  or in part at any  time or  from  time to time  after  the
occurrence  of any of the events  described in Sections  7.3(b),  7.3(c)(i)  and
7.3(c)(ii) of the Reorganization  Agreement or if a Takeover Proposal or Trigger
Event is  consummated  as set  forth in  Section  7.3(d)  of the 


                                      C-1

Reorganization  Agreement.  In the event Acquiror  wishes to exercise the Target
Option, Acquiror shall deliver to Target a written notice (an "Exercise Notice")
specifying the total number of Target Shares it wishes to purchase. Each closing
of a purchase of Target Shares (a "Closing")  shall occur at a place,  on a date
and at a time  designated by Acquiror in an Exercise  Notice  delivered at least
two  business  days prior to the date of the  Closing.  The Target  Option shall
terminate upon the earlier of: (i) the Effective  Time;  (ii) the termination of
the  Reorganization  Agreement  pursuant to Section  7.1  thereof  (other than a
termination  in  connection  with which  Acquiror  is  entitled  to the  payment
specified in Sections 7.3(b),  (c) or (d) thereof);  or (iii) 180 days following
any  termination  of the  Reorganization  Agreement  in  connection  with  which
Acquiror is entitled to the payment  specified in Sections 7.3(b) or (c) thereof
(or if, at the  expiration of such 180-day  period,  the Target Option cannot be
exercised  by  reason  of  any  applicable  judgment,   decree,  order,  law  or
regulation,  ten business days after such impediment to exercise shall have been
removed or shall have become  final and not  subject to appeal,  but in no event
under this clause (iii) later than July 21, 1998; or (iv) 210 days following any
termination of the Reorganization Agreement in connection with which Acquiror is
entitled  to a payment as  specified  in Section  7.3(d)  thereof (or if, at the
expiration  of such 210-day  period,  the Target  Option  cannot be exercised by
reason of any applicable judgment, decree, order, law or regulation, 10 business
days after such  impediment  to exercise  shall have been  removed or shall have
become final and not subject to appeal),  but in no event under this clause (iv)
later than July 21, 1998.  Notwithstanding the foregoing,  the Target Option may
not  be   exercised   if  Acquiror   is  in  material   breach  of  any  of  its
representations, warranties, covenants or agreements contained in this Agreement
or in the Reorganization Agreement or the Confidentiality  Agreement (as defined
in the Reorganization Agreement).

                  11.  Conditions to Closing.  The obligation of Target to issue
the Target Shares to Acquiror  hereunder is subject to the  conditions  that (i)
all waiting periods, if any, under the Hart-Scott-Rodino  Antitrust Improvements
Act of 1976, as amended,  and the rules and regulations  promulgated  thereunder
("HSR Act"),  applicable  to the issuance of the Target Shares  hereunder  shall
have expired or have been terminated;  (ii) all consents,  approvals,  orders or
authorizations of, or registrations,  declarations or filings with, any Federal,
state or local  administrative  agency or  commission  or other Federal state or
local governmental authority or instrumentality,  if any, required in connection
with the issuance of the Target  Shares  hereunder  shall have been  obtained or
made, as the case may be; and (iii) no  preliminary  or permanent  injunction or
other order by any court of  competent  jurisdiction  prohibiting  or  otherwise
restraining such issuance shall be in effect.

                  12.  Closing.  At any  Closing,  (a)  Target  will  deliver to
Acquiror a single  certificate  in definitive  form  representing  the number of
Target Shares designated by Acquiror in its Exercise Notice, such certificate to
be  registered  in the name of  Acquiror  and to bear the  legend  set  forth in
Section 13, and (b) Acquiror will deliver to Target the aggregate  price for the
Target Shares so designated and being  purchased by wire transfer of immediately
available  funds or  certified  check or bank  check.  At any  Closing  at which
Acquiror is  exercising  the Target Option in part,  Acquiror  shall present and
surrender  this  Agreement to Target,  and Target  shall  deliver to Acquiror an
executed new  agreement  with the same terms as this  Agreement  evidencing  the
right to purchase the balance of the shares of Target  Common Stock  purchasable
hereunder.

                                      C-2

take any action which may require Target to make a public announcement regarding
the  possibility  of a business  combination  or merger with such party.  Target
shall not adopt any Rights  Agreement in any manner which would cause  Acquiror,
if Acquiror has complied with its obligations under this Agreement, to become an
"Acquiring  Person"  under  such  Rights  Agreement  solely  by  reason  of  the
beneficial ownership of the shares purchasable hereunder.

pursuant to which  shares of such  party's  common  stock would be  converted in
whole or in part into cash,  other  securities or other  property,  other than a
merger  of such  person  in which  the  holders  of such  party's  common  stock
immediately  prior to the  merger  have  substantially  the  same  proportionate
ownership of common stock of the  surviving  corporation  immediately  after the
merger,  or (2) any sale,  lease,  exchange or transfer (in one transaction or a
series of related  transactions) of all or substantially  all the assets of such
party, or (B) the  shareholders of such party shall approve any plan or proposal
for the liquidation or dissolution of such party,  or (C) any party,  other than
such party or a  subsidiary  thereof or any employee  benefit plan  sponsored by
such  party  or  a  subsidiary  thereof  or a  corporation  owned,  directly  or
indirectly,  by the  shareholders  of  such  party  in  substantially  the  same
proportions  as their  ownership  of  stock  of such  party,  shall  become  the
beneficial  owner of  securities of such party  representing  25% or more of the
combined voting power of then outstanding  securities ordinarily (and apart from

majority  thereof,  unless the election or the  nomination  for election by such
party's  shareholders of each new director  during the period  commencing on the
date of this Agreement and ending on the Expiration  Date was approved by a vote
of at least  two-thirds of the directors then still in office who were directors
at the date  hereof,  or (E) any other event  shall  occur with  respect to such
party that would be  required  to be  reported  in response to Item 6(e) (or any
successor  provision) of Schedule 14A of Regulation  14A  promulgated  under the
Exchange Act.

                  18. Restrictions on Transfer.

                         a.  Restrictions  on Transfer.  Prior to the Expiration
Date,  Acquiror  shall not,  directly  or  indirectly,  by  operation  of law or
otherwise,  sell,  assign,  pledge,  or  otherwise  dispose of or  transfer  any
Restricted  Shares  beneficially  owned by Acquiror,  other than (i) pursuant to
Section 7, or (ii) in accordance with Section 10(b) or 11.


                                      C-6


                         b. Permitted  Sales.  Following the  termination of the
Reorganization  Agreement,  Acquiror  shall be permitted to sell any  Restricted
Shares  beneficially  owned by it if such sale is made  pursuant  to a tender or
exchange offer that has been approved or recommended, or otherwise determined to
be fair and in the best interests of the  shareholders of Target,  by a majority
of the members of the Board of Directors of Target (which majority shall include
a majority of directors who were  directors  prior to the  announcement  of such
tender or exchange offer).

                  19. Registration Rights.

                         a.  Following  the  termination  of the  Reorganization
Agreement,  Acquiror may by written notice (the "Registration Notice") to Target
request  Target  to  register  under the  Securities  Act all or any part of the
Restricted Shares beneficially owned by Acquiror (the "Registrable  Securities")
pursuant to a bona fide firm  commitment  underwritten  public offering in which
Acquiror  and the  underwriters  shall  effect  as wide a  distribution  of such
Registrable  Securities  as is reasonably  practicable  and shall use their best
efforts to prevent  any Person  (including  any Group) and its  affiliates  from
purchasing through such offering  Restricted Shares representing more than 1% of
the  outstanding  shares of Common Stock of Target on a fully  diluted  basis (a
"Permitted  Offering").  The  Registration  Notice shall  include a  certificate
executed by Acquiror and its proposed  managing  underwriter,  which underwriter
shall be an  investment  banking firm of  nationally  recognized  standing  (the
"Manager"),  stating  that (i) they  have a good  faith  intention  to  commence
promptly a Permitted  Offering and (ii) the Manager in good faith believes that,
based  on the then  prevailing  market  conditions,  it will be able to sell the
Registrable  Securities  at a per share  price equal to at least 80% of the Fair
Market  Value of such  shares.  For  purposes of this Section 11, the term "Fair
Market  Value"  shall mean the per share  average of the closing  sale prices of
Target's  Common  Stock on the Nasdaq  National  Market for the ten trading days
immediately  preceding the date of the Registration  Notice.  Target (and/or any
Person  designated by Target) shall  thereupon  have the option  exercisable  by
written notice  delivered to Acquiror within ten business days after the receipt
of the Registration Notice,  irrevocably to agree to purchase all or any part of
the Registrable Securities for cash at a price (the "Option Price") equal to the
product of (i) the number of  Registrable  Securities  and (ii) the Fair  Market
Value of such shares.  Any such  purchase of  Registrable  Securities  by Target
hereunder  shall take place at a closing to be held at the  principal  executive
offices of Target or its counsel at any reasonable  date and time  designated by
Target  and/or  such  designee  in such  notice  within 10  business  days after
delivery of such  notice.  Any payment for the shares to be  purchased  shall be
made by delivery at the time of such closing of the Option Price in  immediately
available funds.


                         c. If Target does not elect to  exercise  its option to
purchase  pursuant to Section 11(a) with respect to all Registrable  Securities,
it shall use its best  efforts  to  effect,  as  promptly  as  practicable,  the
registration under the Securities Act of the unpurchased Registrable Securities;
provided,  however,  that (i)  Acquiror  shall not be  entitled  to more than an
aggregate of two  effective  registration  statements  hereunder and (ii) Target
will not be required to file any such  registration  statement during any period
of time (not to exceed 40 days  after  such  request  in the 


                                      C-7


case of clause  (A) below or 90 days in the case of  clauses  (B) and (C) below)
when (A) Target is in possession  of material  non-public  information  which it
reasonably  believes  would be  detrimental to be disclosed at such time and, in
the  written  opinion of counsel to Target,  such  information  would have to be
disclosed if a  registration  statement  were filed at that time;  (B) Target is
required under the Securities Act to include  audited  financial  statements for
any period in such registration  statement and such financial statements are not
yet  available  for  inclusion  in such  registration  statement;  or (C) Target
determines,  in its reasonable judgment,  that such registration would interfere
with any financing,  acquisition or other material transaction  involving Target
or any of its  affiliates.  If  consummation  of  the  sale  of any  Registrable
Securities  pursuant to a registration  hereunder does not occur within 120 days
after  the  filing  with  the SEC of the  initial  registration  statement,  the
provisions  of this  Section  11  shall  again  be  applicable  to any  proposed
registration;  provided, however, that Acquiror shall not be entitled to request
more than two  registrations  pursuant to this Section 11.  Target shall use its
best efforts to cause any  Registrable  Securities  registered  pursuant to this
Section 11 to be  qualified  for sale under the  securities  or Blue Sky laws of
such  jurisdictions  as Acquiror may reasonably  request and shall continue such
registration or qualification in effect in such jurisdiction; provided, however,
that Target  shall not be  required to qualify to do business  in, or consent to
general service of process in, any jurisdiction by reason of this provision.


                         d. The registration rights set forth in this Section 11
are  subject to the  condition  that  Acquiror  shall  provide  Target with such
information with respect to Acquiror's Registrable Securities, the plans for the
distribution thereof, and such other information with respect to Acquiror as, in
the reasonable  judgment of counsel for Target, is necessary to enable Target to
include  in such  registration  statement  all  material  facts  required  to be
disclosed with respect to a registration thereunder.

                         e.  If  Target's  securities  of the  same  type as the
Registrable  Securities are then  authorized for quotation or trading or listing
on the New York Stock  Exchange,  Nasdaq  National  Market System,  or any other
securities exchange or automated quotations system,  Target, upon the request of
Acquiror,  shall  promptly file an  application,  if required,  to authorize for
quotation,  trading or  listing  the shares of  Registrable  Securities  on such
exchange or system and will use its reasonable  efforts to obtain  approval,  if
required, of such quotation, trading or listing as soon as practicable.

                         f. A registration  effected under this Section 11 shall
be  effected  at  Target's  expense,   except  for  underwriting  discounts  and
commissions  and the fees and the  expenses of counsel to  Acquiror,  and Target
shall provide to the underwriters such  documentation  (including  certificates,
opinions of counsel and  "comfort"  letters from  auditors) as are  customary in
connection  with   underwritten   public  offerings  as  such  underwriters  may
reasonably require. In connection with any such registration,  the parties agree
(i) to indemnify  each other and the  underwriters  in the customary  manner and
(ii) to enter into an underwriting  agreement in form and substance customary to
transactions  of  this  type  with  the  Manager  and  the  other   underwriters
participating in such offering.


                                      C-8



                  20. Adjustment Upon Changes in Capitalization.

                         a. In the event of any change in Target Common Stock by
reason  of  stock  dividends,   splitups,   mergers  (other  than  the  Merger),
recapitalizations,  combinations,  exchange of shares or the like,  the type and
number of shares or securities  subject to the Target  Option,  and the purchase
price per share  provided  in Section 1, shall be  adjusted  appropriately,  and
proper  provision shall be made in the agreements  governing such transaction so
that Acquiror shall receive,  upon exercise of the Target Option, the number and
class of shares  or other  securities  or  property  that  Acquiror  would  have
received  in respect of the Target  Common  Stock if the Target  Option had been
exercised  immediately  prior to such  event or the  record  date  therefor,  as
applicable.

                         b.  In  the  event  that  Target   shall  enter  in  an
agreement: (i) to consolidate with or merge into any person, other than Acquiror
or one of its  Subsidiaries,  and  shall  not  be the  continuing  or  surviving
corporation of such  consolidation or merger;  (ii) to permit any person,  other
than Acquiror or one of its Subsidiaries,  to merge into Target and Target shall
be the continuing or surviving corporation, but, in connection with such merger,
in the  then-outstanding  shares of Target Common Stock shall be changed into or
exchanged for stock or other securities of Target or any other person or cash or
any other property or the outstanding  shares of Target Common Stock immediately
prior to such  merger  shall after such  merger  represent  less than 50% of the
outstanding shares and share equivalents of the merged company; or (iii) to sell
or  otherwise  transfer  all or  substantially  all of its assets to any person,
other than Acquiror or one of its Subsidiaries, then, and in each such case, the
agreement  governing such transaction  shall make proper provisions so that upon
the  consummation of any such  transaction and upon the terms and conditions set
forth herein, Acquiror shall receive for each Target Share with respect to which
the Target Option has not been exercised an amount of  consideration in the form
of and equal to the per share amount of consideration  that would be received by
the holder of one share of Target Common Stock less the Exercise  Price (and, in
the event of an  election  or similar  arrangement  with  respect to the type of
consideration  to be received by the holders of Target Common Stock,  subject to
the foregoing,  proper  provision shall be made so that the holder of the Target
Option would have the same election or similar rights as would the holder of the
number  of shares of Target  Common  Stock for which the  Target  Option is then
exercisable).

                  21. Restrictive Legends. Each certificate  representing shares
of Target  Common Stock issued to Acquiror  hereunder  shall include a legend in
substantially the following form:

                  THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR
SOLD  ONLY  IF SO  REGISTERED  OR IF AN  EXEMPTION  FROM  SUCH  REGISTRATION  IS
AVAILABLE.  SUCH  SECURITIES  ARE ALSO  SUBJECT TO  ADDITIONAL  RESTRICTIONS  ON
TRANSFER AS SET FORTH IN THE STOCK OPTION AGREEMENT,  DATED AS OF JULY 21, 1996,
A COPY OF WHICH MAY BE OBTAINED FROM THE ISSUER.


                                      C-9


                  22. Binding  Effect;  No Assignment.  This Agreement  shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors  and  permitted  assigns.  Except as  expressly  provided for in this
Agreement,  neither this  agreement nor the rights or the  obligations of either
party  hereto are  assignable,  except by  operation of law, or with the written
consent of the other  party.  Nothing  contained in this  Agreement,  express or
implied, is intended to confer upon any person other than the parties hereto and
their  respective  permitted  assigns  any  rights  or  remedies  of any  nature
whatsoever by reason of this Agreement.  Any Restricted  Shares sold by Acquiror
in compliance with the provisions of Section 11 shall, upon consummation of such
sale,  be free of the  restrictions  imposed with respect to such shares by this
Agreement,  unless and until Acquiror shall  repurchase or otherwise  become the
beneficial owner of such shares,  and any transferee of such shares shall not be
entitled to the rights of Acquiror.  Certificates  representing shares sold in a
registered  public offering pursuant to Section 11 shall not be required to bear
the legend set forth in Section 13.

                  23. Specific Performance. The parties recognize and agree that
if for any reason any of the  provisions of this  Agreement are not performed in
accordance  with their specific terms or are otherwise  breached,  immediate and
irreparable  harm or injury would be caused for which money damages would not be
an adequate  remedy.  Accordingly,  each party agrees that, in addition to other
remedies,  the other party shall be entitled to an  injunction  restraining  any
violation or threatened  violation of the provisions of this  Agreement.  In the
event that any action  should be brought in equity to enforce the  provisions of
this  Agreement,  neither  party will allege,  and each party hereby  waives the
defense, that there is adequate remedy at law.

                  24. Entire  Agreement.  This Agreement and the  Reorganization
Agreement  (including the Target Disclosure Schedule and the Acquiror Disclosure
Schedule  relating  thereto)  constitute the entire  agreement among the parties
with  respect  to the  subject  matter  hereof  and  supersede  all other  prior
agreements and  understandings,  both written and oral, among the parties or any
of them with respect to the subject matter hereof.

                  25. Further Assurance. Each party will execute and deliver all
such further  documents and  instruments and take all such further action as may
be necessary in order to consummate the transactions contemplated hereby.

                  26.  Validity.  The  invalidity  or  unenforceability  of  any
provision of this Agreement shall not affect the validity or  enforceability  of
the other  provisions  of this  Agreement,  which shall remain in full force and
effect. In the event any court or other competent  authority holds any provision
of this Agreement to be null,  void or  unenforceable,  the parties hereto shall
negotiate  in good faith the  execution  and  delivery of an  amendment  to this
Agreement  in  order,  as nearly  as  possible,  to  effectuate,  to the  extent
permitted  by law,  the  intent  of the  parties  hereto  with  respect  to such
provision. Each party agrees that, should any court or other competent authority
hold  any  provision  of this  Agreement  or part  hereof  to be  null,  void or
unenforceable,  or order any party to take any action inconsistent  herewith, or
not take any action  required  herein,  the other party shall not be entitled to
specific  performance  of such  provision or part hereof or to any other remedy,
including  but not limited to money  damages,  for breach hereof or of any other
provision  of this  Agreement  or part  hereof as the result of such  holding or
order.

                           (ix) all  fees and  expenses  of  Seller,  including,
                  without  limitation,  fees  and  expenses  of  legal  counsel,
                  accountants  and  financial  advisors,  incurred in connection
                  with the transactions  contemplated  hereby and the Merger and
                  any liability of Seller for Taxes arising from or with respect
                  to the  transactions  contemplated  hereby  other  than  those
                  constituting   Excluded   Liabilities   pursuant   to  Section
                  2.04(ii).

                  (b)    Anything   in   this    Agreement   to   the   contrary
notwithstanding,  this Agreement shall not constitute an agreement to assume any
Assumed Liability if an attempted  assumption thereof,  without the consent of a
third-party  thereto,  would not be binding on such  third-party or would in any
way  adversely  affect the rights of Buyer or Seller  thereunder.  The foregoing
notwithstanding,  Buyer  shall  indemnify  and  hold  harmless  Seller  and  any
affiliate  thereof and the  directors,  officers and  employees of Seller or any
such  affiliate,  from and  against  any and all  losses  arising  out of claims
relating to such Assumed Liabilities to the extent provided in Article XIII.

         2.04.  Excluded  Liabilities.  Notwithstanding  any  provision  in this
Agreement  or any other  writing to the  contrary,  Buyer is  assuming  only the
Assumed Liabilities and is not assuming (i) any liability or obligation relating
to an Excluded Asset arising after the Closing Date or (ii) fifty percent (50%),
up to an aggregate of $550,000,  of the fees and expenses of Seller,  including,
without  limitation,  fees  and  expenses  of  legal  counsel,  accountants  and
financial  advisors,  incurred in connection with the transactions  contemplated
hereby and the Merger and any  liability  of Seller for Tax arising from or with
respect to the transactions contemplated hereby, in each case of whatever nature
whether presently in existence or arising or asserted  hereafter.  The foregoing
liabilities  and  obligations  shall be retained by and remain  obligations  and
liabilities of Seller (such  liabilities and obligations not being assumed being
herein referred to as the "Excluded Liabilities").

         2.05. Assignment of Contracts and Rights. Anything in this Agreement to
the contrary  notwithstanding,  this Agreement shall not constitute an agreement
to  assign  any  Purchased  Asset or any claim or right or any  benefit  arising
thereunder or resulting therefrom if an attempted  assignment  thereof,  without
consent  of  a  third  party  thereto,   would  constitute  a  breach  or  other
contravention  thereof  or in any way  adversely  affect  the rights of Buyer or
Seller thereunder. Seller and Buyer will use their best efforts (but without any
payment of money by Seller or Buyer) to obtain the consent of the other  parties
to any such Purchased Asset or claim or right or any benefit arising  thereunder
for the assignment thereof to Buyer as Buyer may request. If such consent is not
obtained,  or if an attempted  assignment  thereof would be ineffective or would


                                      -7-


adversely affect the rights of Seller thereunder so that Buyer would not in fact
receive all such rights, Seller and Buyer will cooperate in a mutually agreeable
arrangement  under  which  Buyer  would  obtain  the  benefits  and  assume  the
obligations   thereunder   in   accordance   with  this   Agreement,   including
subcontracting,  sublicensing,  or  subleasing  to Buyer,  or under which Seller
would  enforce  for  the  benefit  of  Buyer,   with  Buyer  assuming   Seller's
obligations,  any and all rights of Seller against a third party thereto. Seller
will promptly pay to Buyer when received all monies received by Seller under any
Purchased Asset or any claim or right or any benefit arising thereunder,  except
to the extent the same represents an Excluded  Asset. In such event,  Seller and
Buyer shall,  to the extent the benefits  therefrom and  obligations  thereunder
have not been  provided  by  alternate  arrangements  satisfactory  to Buyer and
Seller, negotiate in good faith an adjustment in the consideration paid by Buyer
for the Purchased Assets.

         2.06.  Purchase Price;  Allocation of Purchase Price.  (a) The purchase
price for the Purchased  Assets (the "Purchase  Price") is (i) the Note and (ii)
the assumption of the Assumed Liabilities.

                  (b) As soon as  practicable  after the  Closing,  Buyer  shall
deliver to Seller a statement (the  "Allocation  Statement"),  setting forth the
value of the  Purchased  Assets,  which shall be used for the  allocation of the
Purchase  Price  (together  with the Assumed  Liabilities)  among the  Purchased
Assets.

                  (c) Seller  shall have a period of fifteen (15) days after the
delivery of the  Allocation  Statement  to present in writing to Buyer notice of
any  objections  Seller may have to the  allocation  set forth in the Allocation
Statement.  Unless Seller timely  objects,  the  Allocation  Statement  shall be
binding on the parties without further adjustment.

                  (d) If Seller  shall raise any  objections  within the fifteen
(15) day period,  Buyer and Seller  shall  negotiate in good faith and use their
best efforts to resolve such  dispute.  If the parties fail to agree within five
(5) days after the  delivery of the  notice,  then the  disputed  items shall be
resolved  by Price  Waterhouse,  LLP,  or if such firm  declines  to act in such
capacity, by such other firm of independent  nationally  recognized  accountants
chosen and mutually  accepted by both parties (the  "Accounting  Referee").  The
Accounting  Referee shall resolve the dispute  within thirty (30) days of having
the item referred to it. The costs, fees and expenses of the Accounting  Referee
shall be borne equally by Seller and Buyer.

                  (e) Seller  and Buyer  agree to report an  allocation  of such
Purchase Price among the Purchased  Assets in a manner entirely  consistent with
the Allocation  Statement  (including  any  adjustment  made pursuant to Section
2.06(d) hereof),  and agree to act in accordance with such Allocation  Statement
in the  preparation  of  financial  statements  and  filing  of all Tax  Returns
(including,  without  limitation,  filing Form 8594 with its Federal  income tax
return for the taxable  year that  includes  the date of the Closing) and in the
course of any tax audit, tax review or tax litigation relating thereto.


                                      -8-


                  (f) No later  than ten (10) days  prior to the filing of their
respective Forms 8594 relating to this transaction,  each party shall deliver to
the other party a copy of its Form 8594.

         2.07. Closing.  The closing (the "Closing") of the purchase and sale of
the Purchased  Assets and the  assumption of the Assumed  Liabilities  hereunder
shall take place at the offices of Testa, Hurwitz & Thibeault,  LLP, High Street
Tower, 125 High Street,  Boston,  Massachusetts 02110, or at such other place as
Buyer and Seller  may  agree,  immediately  prior to the  effective  time of the
Merger.

At the Closing:

                  (a) Buyer shall deliver to Seller the Note.

                  (b)  Seller and Buyer  shall  enter  into the  Assignment  and
Assumption   Agreement,   Assignment  of  Patents,   Assignment  of  Trademarks,
Assignment of Copyrights and Bill of Sale and General  Assignment  substantially
in the forms attached hereto as Exhibits A through E,  respectively,  and Seller
shall deliver to Buyer such quitclaim deeds, endorsements, consents, assignments
and  other  good  and  sufficient   instruments  of  conveyance  and  assignment
(collectively  with the  Assignment  and  Assumption  Agreement,  Assignment  of
Patents, Assignment of Trademarks, Assignment of Copyrights and Bill of Sale and
General  Assignment,  the  "Conveyance  Documents")  as the  parties  and  their
respective  counsel shall deem  reasonably  necessary or  appropriate to vest in
Buyer all right, title and interest in, to and under the Purchased Assets.

                  (c)  Seller  and  Buyer  shall  enter  into the  MICA  License
Agreement and the Preferred Stock Purchase and Noteholder Rights Agreement.

                  (d) Seller and Buyer  shall also  execute and deliver all such
instruments,  documents and  certificates as may be reasonably  requested by the
other party that are necessary, appropriate or desirable for the consummation at
the Closing of the transactions contemplated by this Agreement.

                                   ARTICLE III

that:

         3.01.  Corporate  Existence  and Power.  Seller is a  corporation  duly
incorporated,  validly  existing  and in good  standing  under  the  laws of its
jurisdiction  of  incorporation,  and has all corporate  powers and all material

by  Seller  of this  Agreement  and each of the  Ancillary  Agreements,  and the
consummation by Seller of the transactions  contemplated  hereby and thereby are

Sellers'  shareholders,  have been duly  authorized by all  necessary  corporate
action  on the  part  of  Seller.  This  Agreement  and  each  of the  Ancillary

Seller, except that the enforceability of the indemnification provisions of this
Agreement may be limited by applicable  laws and, with respect to this Agreement
and each of the Ancillary  Agreements,  except that the enforcement of equitable
relief is subject to the discretion of courts in awarding  equitable  relief and
applicable bankruptcy, reorganization, insolvency, moratorium and similar laws.

         3.03.   Governmental   Authorization.   The  execution,   delivery  and
performance by Seller of this Agreement and each of the Ancillary  Agreements do
not  require any action by or in respect of, or filing  with,  any  governmental
body,  agency,  official  or  authority  other  than  (i)  compliance  with  any
applicable requirements of the HSR Act, (ii) compliance with the requirements of
the 1934 Act, (iii) the filing of certain Form UCC-3 termination  statements and
(iii) any action,  which if not taken, or filing,  which if not made, would not,
individually or in the aggregate, have a Material Adverse Effect.

         3.04.  Non-Contravention.  The execution,  delivery and  performance by
Seller of this  Agreement and each of the  Ancillary  Agreements do not and will
not (i)  contravene or conflict with the corporate  charter or bylaws of Seller,
(ii)  assuming  compliance  with  the  matters  referred  to  in  Section  3.03,
contravene  or conflict  with or  constitute a violation of any provision of any
law,  regulation,   judgment,  injunction,  order  or  decree  binding  upon  or
applicable  to Seller or the  Business  or (iii)  assuming  the  receipt  of all
Required  and Other  Consents,  constitute  a default  under or give rise to any
right of termination, cancellation or acceleration of any right or obligation of
Seller or to a loss of any benefit  relating to the  Business to which Seller is
entitled  under any  provision  of any  material  agreement,  contract  or other
instrument binding upon Seller or by which any of the Purchased Assets is or may
be  bound,  or  any  material  license,   franchise,  permit  or  other  similar
authorization affecting, or related in any way to, the Business (the "Permits").

         3.05. Required and Other Consents. (a) Schedule 3.05(a) sets forth each
agreement,  contract  or other  instrument  binding  upon  Seller or any  Permit
requiring a consent as a result of the  execution,  delivery and  performance of

transactions contemplated hereby and thereby, except such consents as would not,
individually or in the aggregate, have a Material Adverse Effect if not received
by the Closing Date (each such consent, a "Required Consent").

                  (b) Schedule 3.05(b) sets forth every other consent (each such
consent,  an  "Other  Consent")  under  such  agreements,   contracts  or  other

         3.06.  Subsidiaries.  (a) Schedule 3.06 sets forth the  Subsidiaries of
Seller.  Each of  Seller's  Subsidiaries  is a  corporation  duly  incorporated,
validly  existing  in  good  standing  under  the  laws of its  jurisdiction  of
incorporation,  has all corporate powers and all material governmental licenses,
authorizations,  consents and approvals required to carry on its business as now
conducted and is duly qualified to do business as a foreign  corporation  and is
in good standing in each jurisdiction  where the character of the property owned
or  leased  by it or the  nature  of its  activities  makes  such  qualification
necessary,  except for those  jurisdictions where the failure to be so qualified
would not, individually or in the aggregate, have a Material Adverse Effect.

                  (b)  All  of  the  outstanding  capital  stock  of,  or  other
ownership  interests  in,  each of  Seller's  Subsidiaries,  is owned by Seller,
directly  or  indirectly,  free and  clear  of any  Lien  and free of any  other
limitation or restriction  (including any restriction on the right to vote, sell
or otherwise dispose of such capital stock or other ownership interests).  There
are no  outstanding  (i)  securities  of  Seller  or  any  of  its  Subsidiaries
convertible  into or  exchangeable  for shares of capital  stock or other voting
securities  or  ownership  interests  in any of  Seller's  Subsidiaries  or (ii)
options or other  rights to acquire  from  Seller or any  obligation  of any its
Subsidiaries to issue, any capital stock,  voting  securities or other ownership
interests in, or any securities convertible into or exchangeable for any capital
stock,  voting  securities or ownership  interests in, any such  Subsidiary (the
items in clauses (i) and (ii) being referred to  collectively as the "Subsidiary
Securities").  There  are no  outstanding  obligations  of  Seller or any of its
Subsidiaries  to  repurchase,   redeem  or  otherwise  acquire  any  outstanding
Subsidiary Securities.

limited to machinery,  equipment,  furniture, vehicles, storage tanks, spare and
replacement parts, fuel and other trade fixtures and fixed assets, and any Liens
thereon,  specifying in the case of leases or subleases,  the name of the lessor
or sublessor, the lease term and basic annual rent.

         3.08.  Litigation.  Except as set forth on Schedule  3.08,  there is no
action,  suit,  investigation  or  proceeding  (or any basis  therefor)  pending
against,  or to the knowledge of Seller,  threatened  against or affecting,  the
Business  or  any  Purchased  Asset  before  any  court  or  arbitrator  or  any
governmental  body, agency or official that, if determined or resolved adversely
in accordance with the plaintiff's demands, would reasonably be expected to have
a Material Adverse Effect or that in any manner  challenges or seeks to prevent,
enjoin, alter or materially delay the transactions contemplated hereby.

         3.09.  Finders' Fees.  Except for Allen & Company  Incorporated,  whose
fees will be paid by  Seller,  subject to the limits of  Sections  2.03(ix)  and
2.04(ii),  there  is no investment banker,  broker, finder or other intermediary
which has been retained by or is authorized to act on behalf of 

                                      -11-


Seller who might be entitled to any fee or  commission  from Buyer or any of its
Affiliates upon consummation of the transactions contemplated by this Agreement.

         3.10. Opinion of Financial Advisor.  Seller has been advised in writing
by its financial advisor,  Allen & Company Incorporated,  that in such advisor's
opinion,  as of the date hereof,  the  consideration to be received by Seller in
connection with the  transactions  contemplated  hereby is fair to Seller from a
financial point of view.

Documents  as of  March  30,  1996  and in any  subsequently  filed  Seller  SEC
Documents  are stated  consistently  with the audited  financial  statements  of

the ordinary  course of business  consistent  with past practices to provide for
all slow-moving,  obsolete, or unusable inventories to their estimated useful or
scrap  values and such  inventory  reserves  are  adequate  to provide  for such
slow-moving, obsolete or unusable inventory and inventory shrinkage.

         3.12. Accounts  Receivable.  The accounts  receivable  disclosed in the
Seller SEC  Documents  as of March 30,  1996,  and,  with  respect  to  accounts
receivable  created since such date,  disclosed in any subsequently filed Seller
SEC  Documents,  or as accrued on the books of Seller in the ordinary  course of
business  consistent with past practices in accordance  with generally  accepted
accounting  principles since the last filed Seller SEC Documents,  represent and
will represent bona fide claims against debtors for sales and other charges, are
not subject to discount except for normal cash and immaterial  trade  discounts,
and the amount earned for doubtful accounts and allowances  disclosed in each of
such Seller SEC Document or accrued on such books is  sufficient  to provide for
any losses that may be sustained on realization of the receivables.

         3.13. Customers and Suppliers. As of the date hereof, no customer which
individually accounted for more than 1% of Seller's gross revenues during the 12
month  period  preceding  the date hereof has  indicated  to Seller that it will
stop, or decrease the rate of, buying services or products of Seller,  or has at
any time on or after  March  30,  1996  decreased  materially  its  usage of the
services or products of Seller.  As of the date hereof,  no material supplier of
Seller has  indicated  that it will stop,  or  decrease  the rate of,  supplying
materials, products or services to Seller. Seller has not knowingly breached, so
as to provide a benefit to Seller  that was not  intended  by the  parties,  any
agreement  with,  or engaged in any  fraudulent  conduct  with  respect  to, any
customer or supplier of Seller.

         9.02.  Employees and Offers of  Employment.  On or prior to the Closing
Date,  Buyer may offer employment to any or all of the employees of the Business
listed on  Schedule  9.02(a)  who are "active  employees"  on the Closing  Date;
provided,  that  Buyer may  terminate  at any time  after the  Closing  Date the
employment of any employee who accepts such offer.  For purposes of this Article
IX, the term "active  employee"  shall mean any Person who, on the Closing Date,
is  actively  employed  by  Seller  or who is on  short-term  disability  leave,
authorized  leave of absence,  military service or lay-off with recall rights as
of the Closing Date (such  inactive  employees  shall be offered  employment  by
Buyer as of the date they return to active  employment),  but shall  exclude any
other inactive or former employee including any Person who has been on long-term
disability  leave or unauthorized  leave of absence or who has terminated his or
her  employment,  retired or died on or before the Closing Date. Any such offers
shall be at such salary or wage and  benefit  levels and on such other terms and
conditions as Buyer shall in its sole discretion deem appropriate. The employees
who accept and  commence  employment  with  Buyer are  hereinafter  collectively
referred to as the  "Transferred  Employees."  Seller will not take,  any action
that would impede, hinder, interfere or otherwise compete with Buyer's effort to
hire any Transferred  Employees.  Buyer will not discuss nor offer employment to
the employees listed on Schedule 9.02(b).

         9.03.  Assumption of Seller's Employee Plans and Benefit  Arrangements.
Each of Seller's  Employee Plans and Benefit  Arrangements is listed on Schedule
9.03.  As of the Closing  Date Buyer shall  adopt and assume  Seller's  Employee
Plans and Benefit  Arrangements  on behalf of the  employees  listed on Schedule
9.02(a).

         9.04.  Buyer  Benefit  Plans.  Buyer  or  one of  its  Affiliates  will
recognize  all service of the  Transferred  Employees  with Seller or any of its
Affiliates, for purposes of eligibility to participate in those employee benefit
plans,  within the meaning of Section  3(3) of ERISA,  in which the  Transferred
Employees are enrolled by Buyer or one of its Affiliates  immediately  after the
Closing Date. Any medical plan adopted by Buyer after the Closing, to the extent
available  on  commercially  reasonable  terms,  shall  contain no  pre-existing
exclusions and shall provide credit for deductibles and co-payments for the 1996
calendar  year so that the  Transferred  Employees  shall not be entitled to any
continuation  coverage under Seller's plans pursuant to the Consolidated Omnibus
Budget Reconciliation Act of 1985, as amended.

         9.05. No Third Party Beneficiaries.  No provision of this Article shall
create any third party  beneficiary  or other  rights in any  employee or former
employee (including any beneficiary or dependent thereof) of Seller or of any of
its subsidiaries in respect of continued employment (or resumed employment) with
either Buyer or the Business or any of their Affiliates and no provision of this
Article IX shall  create any such  rights in any such  Persons in respect of any
benefits that

                                      -20-


may be provided,  directly or  indirectly,  under any  Employee  Plan or Benefit
Arrangement or any plan or  arrangement  that may be established by Buyer or any
of its Affiliates.  No provision of this Agreement shall constitute a limitation
on rights to amend, modify or terminate after the Closing Date any such plans or
arrangements of Buyer or any of its Affiliates.

                                   ARTICLE XI

                                 INDEMNIFICATION



         11.01. Indemnification. (a) Buyer shall, for a period of ten (10) years
from the Closing Date, indemnify and hold harmless Seller, any Affiliate thereof
and the directors,  officers, employees, counsel or agents of Seller or any such
Affiliate, from and against any losses, claims, demands,  actions,  proceedings,
damages,   liabilities  or  expenses  arising  out  of,  resulting  directly  or


                                      -22-


indirectly  from,  or relating  to (i) the  Purchased  Assets,  (ii) the Assumed
Liabilities,  including,  without  limitation,  any  obligations  or liabilities
resulting from the actions,  suits,  investigations  or proceedings set forth on
Schedule 3.08, (iii) the transactions  contemplated hereby or (iv) the Business,
either preceding or after the Closing;  provided that such indemnification shall
be subject to any limitation  imposed from time to time under applicable law and
provided further that Buyer's liability for  indemnification  hereunder shall be
reduced by any amounts recovered by Seller under any insurance policy.

                  (b)  Seller  shall,  for a period of ten (10)  years  from the
Closing Date,  indemnify and hold harmless the directors,  officers,  employees,
counsel  or agents  of Buyer or any  affiliate  thereof,  from and  against  any
losses, claims, demands,  actions,  proceeds,  damages,  liabilities or expenses
arising out of,  resulting  directly or indirectly  from, or relating to (i) the
Excluded   Assets  or  (ii)  the  Excluded   Liabilities;   provided  that  such
indemnification  shall be subject to any  limitation  imposed  from time to time
under applicable law.

         11.02.  Procedures;  No Waiver. (a) Seller agrees to give prompt notice
to Buyer of the  assertion of any claim,  or demand or the  commencement  of any
suit,  action or  proceeding  in respect of which  indemnity may be sought under
such Section  11.01;  provided that the failure to provide such prompt notice to
Buyer  shall  not  relieve  Buyer of any  liability  which it may have to Seller
unless such failure has prejudiced the defense of such  litigation.  Buyer shall
assume the defense of each action,  suit,  investigation or proceeding set forth
on  Schedule  3.08.  In  addition,  in the event any  additional  action,  suit,
investigation  or  proceeding  is  brought  against  Seller in  respect of which
indemnity  may be  sought  under  Section  11.01,  Buyer  shall be  entitled  to
participate  therein and assume the defense  thereof;  unless,  however,  Seller
reasonably  determines  that  defenses  may be available to Seller which are not
available to Buyer and may/or may not be consistent  with the best  interests of
Buyer.  In such event,  Seller  shall have the right to assume its own  defense,
with counsel  reasonably  satisfactory  to Buyer,  and shall signify by promptly
notifying  Buyer in writing of its  decision.  Such  decision  shall not relieve
Buyer of any  liability it may have to Seller;  provided  that in such event the
legal or other expenses  incurred in connection  with Seller's  defense shall be
borne by Seller.  Neither  Buyer nor Seller shall  compromise  or consent to the
entry of any judgment as to any pending,  threatened  or future  claim,  action,
investigation  or  proceeding  without the prior  written  consent of the other,
which  consent shall not be  unreasonably  withheld.  Without  limitation of the
foregoing,  in the event Seller or Buyer is or becomes  involved in any capacity
in any action, proceeding or investigation (collectively,  a "Claim"), for which
indemnification is available,  Buyer in the case of a Claim involving Seller and
Seller  in the case of a Claim  involving  Buyer,  shall  pay as  incurred  such
indemnified  party's reasonable legal and other expenses  (including the cost of
any investigation and preparation) incurred in connection therewith.

                  (b) No waiver of a closing condition by either Buyer or Seller
shall limit its rights under Section 11.01.

                                   ARTICLE XII

                                   TERMINATION



         12.01. Grounds for Termination. This Agreement may be terminated at any
time prior to the Closing:

                           (i)  by mutual written agreement of Seller and Buyer;

                           (ii) by either Seller or Buyer,  if, without fault of
                  the  terminating  party,  the  Closing  shall  not  have  been
                  consummated on or before December 31, 1996 (or such later date
                  as may be agreed upon in writing by the parties hereto);

                           (iii) by either Seller or Buyer if there shall be any
                  law  or  regulation   that  makes  the   consummation  of  the
                  transactions   contemplated   hereby   illegal  or   otherwise
                  prohibited or if consummation of the transactions contemplated
                  hereby would violate any nonappealable  final order, decree or
                  judgment of any court or  governmental  body having  competent
                  jurisdiction; or

                           (iv)  by  either   Seller  or  Buyer  if  the  Merger
                  Agreement is terminated  pursuant to the provisions  contained
                  therein.

         The party desiring to terminate this Agreement pursuant to clauses (ii)
or (iii) shall give notice of such termination to the other party.

         12.02.  Effect  of  Termination.  Subject  to  Section  13.03,  if this
Agreement is terminated as permitted by Section 12.01, such termination shall be
without  liability  of either  party  (or any  shareholder,  director,  officer,
employee,  agent, consultant or representative of such party) to the other party
to this Agreement;  provided that (a) if such termination  shall result from the
willful failure of either party to fulfill a condition to the performance of the
obligations  of the other  party or to perform a covenant of this  Agreement  or
from a willful  breach by either  party to this  Agreement,  such party shall be
fully liable for any and all Losses incurred or suffered by the other party as a
result of such failure or breach.  The provisions of Sections  6.01(a) and 13.03
shall survive any termination hereof pursuant to Section 12.01.

all of the right,  title and  interest of Seller in, to and under the  Purchased

any or any material  portion of any of the  Contracts or Permits if an attempted
sale,  assignment,  transfer or delivery,  without the consent of a third party,
would constitute a breach or other contravention thereof or in any way adversely
affect the rights of Buyer or Seller thereunder.

            (b) Buyer does hereby  accept all the right,  title and  interest of
Seller in, to and under all of the Purchased  Assets  (except as aforesaid)  and

embedded in Licensee Products.  Licensee may not otherwise use or sublicense the
Licensed Mark without Licensor's prior written consent.

                              Licensee  hereby  acknowledges  that the  Licensed
Mark is owned solely and exclusively by Licensor and agrees that,  except as set
forth  herein,  Licensee has no rights,  title or interest in or to the Licensed

                           Quality Standards.

                              Licensor  shall  control  the  quality of Licensee
Products  sold under or otherwise  bearing or  referencing  the  Licensed  Mark.
Licensee  shall  furnish to  Licensor,  at no expense  to  Licensor,  reasonable
quantities of  pre-production  samples of all such Licensee Products in the form
that Licensee  intends to  manufacture  and sell to allow Licensor to review the
quality of the Licensee  Products,  and, if the samples meet Licensor's  quality
control  requirements  (which shall be  comparable  to the quality of Licensor's
products sold under the Licensed Mark, if any), Licensor shall approve the level
of quality of such samples.  Thereafter,  upon the request of Licensor, Licensee
shall furnish,  at no expense to Licensor,  reasonable  quantities of production
samples of such  Licensee  Products to allow  Licensor to monitor the quality of
such Licensee Products.  Any information  provided by Licensee to Licensor under
this Section  5.b.(1) shall be deemed  Confidential  Information  (as defined in
Section 10 below) of Licensee.

                              Licensor shall have the right to request  Licensee
to make any  changes  and/or  corrections  to such  Licensee  Products as may be
required to  maintain  the quality  standard  prescribed  by Licensor in Section
5.b.(1)  above,  and  Licensee  agrees to make and  incorporate  said changes or
corrections at Licensee's  sole cost and expense.  If Licensee does not make and

                           Warranty Disclaimer.  Licensee agrees that the rights
granted  herein with respect to the Licensed  Mark exist only to the extent that

                              Use and Display of Licensed Mark.

                              Licensee  agrees  to  use  the  Licensed  Mark  in

have the right to use the Licensed  Mark in any manner that  conflicts  with the
rights of any third party.  If Licensee's use of the Licensed Mark infringes the
rights  of any  third  party or  weakens  or  impairs  Licensor's  rights in the

in accordance  with  Licensor's  instructions.  In the event  Licensee  fails to
terminate or modify such use as directed by Licensor,  Licensor may, in its sole
discretion,  terminate the license  granted in this Section 5 in connection with
the Licensed Mark.

                       Maintenance and Support.


                                      F-5


                              Licensee  shall be  responsible  for providing all
first level customer maintenance and support for Licensee Products. If, however,
Licensee is not able to diagnose or replicate a customer problem relating to the
Licensed  Technology by using the object code version of the Licensed Technology
and source code of the Licensed Technology is necessary to diagnose or replicate
such problem,  Licensee shall  immediately  notify Licensor,  and Licensor shall
then be responsible for diagnosing or replicating such problem.

                              During the term of this  Agreement,  Licensor will
provide  second level  telephone  support or, at Licensor's  option,  electronic
support to  Licensee  during  Licensor's  normal  business  hours for  answering
questions  regarding  the Licensed  Technology.  During the Initial  Term,  such
support shall be free of charge;  during the Renewal Term, Licensee shall pay to
Licensor  a  support  fee to be  negotiated  by the  parties  in good  faith and
mutually agreed upon prior to the expiration of the Initial Term.  Licensee must
designate one (1) individual for handling all  maintenance  and support  contact
and  communications  with Licensor and shall,  within thirty (30) days after the
Effective Date,  provide Licensor with the name of such individual.  Thereafter,
Licensee may designate  successor  individuals  upon ten (10) days prior written
notice.

                              If  Licensee   desires   maintenance  and  support
services from Licensee beyond those set forth in Sections 6.a and 6.b above, the
parties  shall  negotiate  in good  faith a  separate  maintenance  and  support
agreement and a separate  maintenance  and support fee to be paid by Licensee to
Licensor thereunder.

                              Licensor shall provide  Licensee with Updates,  if
any, in object code form as soon as reasonably practicable after completion, but
in any event within thirty (30) days after such completion. If Licensor provides
or makes  available to Licensee any Update and Licensee does not implement  such
Update in Licensee  Products,  Licensor shall be responsible  for supporting (as
set forth in Sections 6.a and 6.b above) the Licensed  Technology  existing just
prior to such Update only for a period of six (6) months following the date upon
which Licensor makes such Update available to Licensee.

                              In  addition  to  the   maintenance   and  support
obligations of Licensor set forth in Sections 6.a, 6.b and 6.d above, during the
term of this Agreement, Licensor agrees to assist Licensee in developing certain
Derivative  Works to the following extent and subject to the following terms and
conditions:

                              Licensee  may request  Licensor to designate up to
two (2) (or such other  number as may be mutually  agreed  upon by Licensor  and
Licensee in writing) of Licensor's  existing engineer  employees to be dedicated
full-time to develop  certain  Derivative  Works of the Licensed  Technology  in
connection with Licensee's  commercialization  of the Licensed Technology in the
LAN  server  and WIC  card  markets  ("Development  Projects"),  subject  to the
following  conditions:  (a) each  Development  Project  shall be  pursuant  to a
written statement of work provided by Licensee ("Statement of Work") which shall
be  in  sufficient  detail  to  allow  Licensor's  employees  to  complete  such
Development   Project,  and  (b)  Licensee  shall  pay  to


                                      F-6

Licensor Licensor's  then-prevailing  non-recurring engineering ("NRE") fees and
all  reasonable  out-of-pocket  expenses  in  connection  with each  Development
Project.

                              If, in Licensor's sole  discretion,  Licensor does
not have  available  the  requested  number of existing  engineer  employees  to
dedicate to a Development Project,  Licensor agrees to use reasonable efforts to
hire such number of engineer  employees or contractors  subject to the following
conditions:  (a)  Licensee  shall  pay  to  Licensor  an NRE  fee  in an  amount
sufficient to reimburse Licensor for such employees' and consultants'  salaries,
benefits,  fees and overhead, as well as all reasonable  out-of-pocket  expenses
incurred in connection with such  development  work, (b) Licensee shall pay such
NRE fees for a minimum of one (1) year and (c) if, at any time  during  such one
(1) year period,  such Licensor  employees or contractors are not working on any
Development  Projects  for  Licensee,  Licensor  shall be free to  utilize  such
employees or  contractors  for  Licensor-related  projects  and matters  without
reimbursement to Licensee of any NRE fees, or any portion thereof.

                              All  payments  due to Licensor  under this Section
6.e.  shall be paid by Licensee to Licensor  within  fifteen (15) days after its
receipt  of  an  invoice  from  Licensor.  Licensor  shall  have  the  right  to
immediately  terminate  all  obligations  under this  Section  6.e. and all work
relating to any and all  Development  Projects if Licensee fails to pay Licensor
any amounts due  hereunder  within  fifteen  (15) days after  Licensor  notifies
Licensee in writing of any delinquent amounts due under this Section 6.e.

                              All  Licensor  employees  working  on  Development
Projects shall be under the direct  supervision and instructions of Licensor and
all Licensor  contractors  working on  Development  Projects  shall be under the
general direction of Licensor. All such Licensor employees and contractors shall
have  access  to the  source  code and  related  documentation  of the  Licensed
Technology and such other  materials and  information  in Licensor's  possession
that are necessary to perform work under the Development Projects.

                              All  Derivative  Works  created  or  developed  by
Licensor  employees  and  contractors  in  performing  work  under  any  and all
Development  Projects  shall be (a) owned  solely  by  Licensor  and (b)  deemed
included  within the  definition  of Licensed  Technology  for  purposes of this
Agreement.

                              ALL  SERVICES  AND  WORK   PERFORMED  BY  LICENSOR
EMPLOYEES AND CONTRACTORS IN CONNECTION ANY AND ALL DEVELOPMENT PROJECTS AND ALL
RESULTS  THEREOF  (INCLUDING,  WITHOUT  LIMITATION,  ALL  DERIVATIVE  WORKS) ARE
PROVIDED "AS IS" WITHOUT ANY REPRESENTATIONS OR WARRANTIES OF ANY KIND.

                           Licensee Covenants and Representations.

         Except as expressly and unambiguously provided herein and as conditions
of Licensee's license hereunder, Licensee represents, warrants and agrees:


                                      F-7


                              not to modify or create any Derivative Work of the
Licensed Technology or any portion thereof;

                              not to delete,  alter, add to or fail to reproduce
in and on any Licensee  Products any copyright,  trademark (if such trademark is
used by Licensee) or other notices  appearing in or on any copy,  media,  master
disk or package materials  containing or relating to the Licensed Technology and
provided by Licensor or which may be required by Licensor at any time;

                              not  to  reverse   assemble,   reverse   engineer,
decompile,  or otherwise attempt to derive source code (or the underlying ideas,
algorithms,  structure or organization) from the Licensed Technology or from any
other information;

                              not  to  develop,  have  developed,  market,  have
marketed or assist any third party in  developing  or  marketing  digital  modem
technology  similar to the Licensed  Technology  for a period of three (3) years
after the Effective Date. If after such three (3) year period Licensee develops,
has developed or assists a third party in developing  digital modem  technology,
such development  must not copy,  utilize or be based on or be a Derivative Work
of, in whole or in part, any Licensed Technology. This Section 7.d shall survive
any termination of this Agreement by Licensor  pursuant to Section 9.a.(3) below
due to Licensee's uncured breach.

                              to use the Licensed Mark only in  connection  with
Licensee  Products  (but will not represent or imply that it is Licensor or is a
part of  Licensor).  Licensee  will  not  contest  the use by or  authorized  by
Licensor of the  Licensed  Mark or any  application  or  registration  therefor,
whether during or after the term of this Agreement;

                              to  keep  Licensor  informed  as to  any  problems
encountered  with the Licensed  Technology  and any  resolutions  arrived at for
those  problems.  If  Licensor  makes  any  modifications,   design  changes  or
improvements of the Licensed  Technology based on suggestions by Licensee or any
of its customers, distributors, employees or agents, Licensor shall have any and
all right, title and interest in and to any such suggested modifications, design
changes or improvements;

                              during  the  Initial  Term  and  Renewal  Term (if
Licensee  sublicenses  the  Licensed  Technology  pursuant  to Section 2.b above
during the Initial Term and/or  Renewal Term),  to provide  Licensor with annual
written reports of the total number of sublicensee  products sold within fifteen
(15) days after the end of each of Licensee's  fiscal years.  Such reports shall
accompany the payments specified in Sections 2.b above. In addition,  during the
Renewal Term,  Licensee shall provide  Licensor with periodic written reports of
the total number of Licensee  Products sold. The frequency of such reports shall
be mutually  agreed upon by the parties at such time the parties  agree upon the
royalties  to be paid  Licensor  under  Section 3.b above.  Such  reports  shall
accompany the payments specified in Section 3.b above.

                              to keep complete and accurate books and records of
its  sales,  customers  and  end  users  of  Licensee  Products  and  all  other
transactions  relating to  Licensed

Technology.  Licensor  shall have the right (upon  reasonable  notice and during
Licensee's  normal  business  hours)  to have an  independent  certified  public
accountant  inspect and audit the books and records of Licensee  for the purpose
of  verifying  Licensee's  compliance  with the  terms  and  conditions  of this
Agreement and any reports,  information  or payments  provided or due hereunder.
All underpayments revealed by such audit shall be paid to Licensor within thirty
(30) days of the audit  results.  The cost of such  audit  shall be borne by the
Licensor,  except  that if such audit  reveals an  underpayment  to  Licensor in
excess of five  percent  (5%),  Licensee  shall  bear the  expense of the audit.
Licensor  may  exercise its right to audit no more than once each year unless an
audit reveals  Licensee's  non-compliance  with the terms and conditions of this
Agreement or an underpayment hereunder of over five percent (5%), in which event
Licensor  shall have the right to audit more  frequently  (but no more than once
every three (3) months)  until the results of the last audit  reveal  Licensee's
compliance  with the terms and conditions of this Agreement and less than a five
(5%) underpayment hereunder.

                              to comply  with all export  laws and  restrictions
and  regulations of the Department of Commerce or other United States or foreign
agency or authority,  and not to export,  or allow the export or reexport of any
Proprietary Information (as defined in Section 10 below), Licensed Technology or
Licensee  Products  or any  direct  product  thereof  in  violation  of any such
restrictions,  laws or regulations, or to Afghanistan,  the People's Republic of
China  or any  Group  Q, S, W, Y or Z  country  specified  in the  then  current
Supplement No. 1 to Section 770 of the U.S.  Export  Administration  Regulations
(or any successor supplement or regulations); Licensee shall obtain and bear all
expenses  relating to any necessary  licenses and/or  exemptions with respect to
the export from the U.S. of all material or items deliverable by Licensor to any
location and shall  demonstrate to Licensor  compliance with all applicable laws
and regulations prior to delivery thereof by Licensor;

                              that  all  advertising  and  marketing   materials
relating to the Licensed Technology shall be accurate in all respects.  Licensee
agrees to provide Licensor with copies of all brochures, advertisements,  direct
mail  materials  and  all  other  marketing  materials  regarding  the  Licensed
Technology  for  Licensor's  prior  review  and  approval  which  shall  not  be
unreasonably  withheld or delayed. The purpose of such review shall be to verify
the accuracy of such materials  with respect to the Licensed  Technology and the
appropriate  usage of the  Licensed  Mark and  proprietary  notices  (including,
without limitation,  trademark and copyright notices). Licensor shall approve or
disapprove  such  materials  within  ten  (10)  business  days of  receipt  from
Licensee.  Licensee  agrees to correct all errors and  omissions  as required by
Licensor prior to the  distribution  of such  materials.  Licensee shall provide
Licensor with copies of such materials sufficiently in advance to allow adequate
time for Licensor to correct any errors or omissions and for Licensee to correct
such errors or omissions.

provided  herein or renewed as  provided in Section  8.b below,  this  Agreement
shall  commence  on the  Effective  Date and  shall  terminate  three  (3) years
thereafter ("Initial Term").


                                      F-9


                              Renewal Term. Upon expiration of the Initial Term,
this  Agreement  shall  automatically  renew  for an  additional  two (2)  years
("Renewal  Term"),  provided,  however,  that the  parties  mutually  agree on a
royalty  rate to be paid by  Licensee to  Licensor  during the Renewal  Term for
Licensee's  right to continue  exercising the license rights granted  hereunder.
Such royalty rate shall be  negotiated by the parties in good faith and mutually
agreed upon prior to the  expiration of the Initial Term.  Such mutually  agreed
upon royalty rate and related payment terms and conditions shall be set forth in
a written amendment to this Agreement signed by both parties.

                        Termination.

                              This  Agreement  may be  terminated by a party for
cause immediately upon the occurrence of any of the following events:

                                         if the other ceases to do business,  or
otherwise terminates its business operations; or

                                         if the  other  shall  fail to  promptly
secure or renew any license,  registration,  permit,  authorization  or approval
necessary  for the conduct of its  business in the manner  contemplated  by this
Agreement,  or if any  such  license,  registration,  permit,  authorization  or
approval is revoked or suspended and not reinstated within thirty (30) days; or

                                         if the other  materially  breaches  any
material  provision  of this  Agreement  and  fails to cure such  breach  within
forty-five (45) days (and  immediately in the case of a breach of Section 10) of
written notice describing the breach; or

                                         if  the  other  shall  seek  protection
under  any  bankruptcy,   receivership,   trust  deed,  creditors   arrangement,
composition or comparable  proceeding,  or if any such  proceeding is instituted
against the other (and not dismissed within ninety (90) days).

                              Licensor may terminate this Agreement  immediately
upon the occurrence of any of the following events:

                                         if   Licensee    defaults   under   the

relinquishment  or other  disposition of all or substantially  all of Licensee's
assets,  stock or business or of  controlling  interest in Licensee  (whether by
operation of law or otherwise) to, Bay Networks,  Ascend,  3COM, U.S.  Robotics,
Shiva or Cascade, or any subsidiary or affiliate of any of the foregoing.

                              Neither party shall incur any liability whatsoever
for any damage,  loss or expenses of any kind  suffered or incurred by the other
(or  for  any  compensation  to the  other)  arising  from  or  incident  to any
termination  of this Agreement by such party that complies with the terms of the
Agreement  whether  or not such  party is  aware  of any  such  damage,  loss or
expenses.

                              Upon termination of this Agreement by either party
or  naturally  at the end of the Renewal  Term,  (i) all rights and  licenses of
Licensee and obligations of and restrictions on Licensor and Licensee  hereunder
shall  terminate,  except as expressly  set forth in  subclause  (iii) below and
except  that end  user  licenses  granted  to  Licensee  Products  customers  in

                              Termination  is not the  sole  remedy  under  this
Agreement and,  whether or not termination is effected,  all other remedies will
remain available.

                           Confidentiality.

                              Each party agrees that all inventions  (whether or
not  patentable),  trade  secrets,  ideas,  processes,  source  code,  formulas,
technology, know-how and all other business, technical and financial information
it obtains from the other are the confidential  property of the disclosing party
("Proprietary  Information").  Except as expressly  allowed in this Agreement or
for purposes  contemplated by this  Agreement,  the receiving party will hold in
confidence and not use or disclose any Proprietary Information of the disclosing
party.  The receiving  party shall not be obligated under this Section 10.a with
respect to information the receiving party can document:

           TRADEMARK REGISTRATIONS AND APPLICATIONS FOR LICENSED MARK

                           TRADEMARK USAGE GUIDELINES


                  Trademarks Must be Identified as Trademarks.  A trademark is a
word (or  several  words),  name or  symbol  used to  identify  the  source of a
product. It distinguishes  Telebit's products from those of other manufacturers.
Two symbols  commonly alert the public that a word is being used as a trademark,
the letters "(TM)" or the symbol "(R)" (circle "R"). The "(R)" symbol is only to
be used when the U.S. Patent and Trademark  Office has registered the trademark.
All other trademarks must be designated using the letters "(TM)."

                  Always Use a Trademark  as an  Adjective.  A  trademark  is an
adjective;  never use a trademark as a noun.  Trademarks  should never appear in
the plural form (i.e. it is incorrect to say "two  Micas("TM").  The correct way
to refer to more than one product is to say "two  Mica(TM)  modems."  Trademarks
should never  appear in the  possessive  form (i.e.  it is incorrect to say "The
Mica's main  features  include..."  Instead say "the Mica(TM)  modem's  features
include..."). An easy test is to remove the trademark from your sentence; if you
have a complete sentence remaining,  you probably used the trademark  correctly.
This is important to keep the trademark from becoming a generic term.

                  Use Appropriate  Trademark  Symbols and Identify the Trademark
Owner. When using Telebit's trademarks in advertising and printed material, they
must appear as provided by Telebit.  The first time the  trademark  appears on a
document,  identify it as a trademark by using a superscript "(TM)" or "(R)", as
appropriate.  When using multiple trademarks in a document,  it may be easier to
identify the owners of each at the end of the document.

For example:

                  ABC(R) is a registered trademark of XYZ Corporation.
                  MICA(TM) is a trademark of Telebit Corporation

                  All usage of the MICA  trademark  shall  include  (TM) symbol.
After Telebit has received federal  registration for the MICA mark, all usage of
the MICA mark shall include the registered  trademark symbol and shall be in the
following  form:  MICA(R).  Telebit will notify  Licensee when the MICA mark has
been  federally  registered.  All  literature,   documentation,   packaging  and
materials  printed,  distributed or  electronically  transmitted by Licensee and
containing the MICA mark shall include the following notice:

                  MICA(TM) is a trademark of Telebit Corporation.

After the MICA mark is federally  registered,  all such literature and materials
shall include the following notice:

                  MICA(R) is a registered trademark of Telebit Corporation.

days after any such  sublicense  agreement  is entered  into.  Such notice shall
include the name of the sublicensee and the effective date and termination  date
(if any) of the sublicense.

distribution of Licensee  Products provided that any such distributors are bound
in writing to all the limitations and restrictions on Licensee contained in this

Licensor's  marketing or  distribution  activities or its  appointment  of other
licensees,  dealers,  distributors,  value-added  resellers,  original equipment
manufacturers, or agents anywhere in the world.

                               Notwithstanding  anything else,  Licensor retains

agrees:

                               to  keep  Licensor  informed  as to any  problems
encountered  with the Licensed Patent Rights and any resolutions  arrived at for

comparable proceeding, or if any such proceeding is instituted against the other
(and not dismissed within ninety (90) days).

upon the occurrence of any of the following events:

                               if Licensee  defaults under the Promissory  Note;
or

                               upon any  merger  or  consolidation  of  Licensee
with, or any sale, lease, exchange,  mortgage, pledge, transfer,  relinquishment
or other disposition of all or substantially all of Licensee's assets,  stock or
business or of controlling  interest in Licensee (whether by operation of law or
otherwise) to, Bay Networks,  Ascend, 3COM, U.S. Robotics,  Shiva or Cascade, or

                               Neither   party   shall   incur   any   liability
whatsoever for any damage,  loss or expenses of any kind suffered or incurred by
the other (or for any compensation to the other) arising from or incident to any
termination  of this Agreement by such party that complies with the terms of the

termination of this Agreement:  Sections 2.e, 4.b, 6.c, 6.d, 6.e, 9, 10, 11, 12,

remain available.

proceedings  unless  Licensee and other licensees of the Licensed Patent Rights,

to bear the cost of prosecution and maintenance with respect to any given patent
application or patent upon sixty (60) days prior written notice to Licensor.  In

maintenance of such patent application or patent and (ii) Licensee shall have no
further right or license thereunder.

                                    if the other shall seek protection under any

comparable proceeding, or if any such proceeding is instituted against the other
(and not dismissed within ninety (90) days).

or other disposition of all or substantially all of Licensee's assets,  stock or

whatsoever for any damage,  loss or expenses of any kind suffered or incurred by
the other (or for any compensation to the other) arising from or incident to any

expenses.

                           Patent Prosecution and Maintenance.

prosecuting  and  maintaining  such patent  applications  and patents  provided,
however,  that in the  event  Licensor  grants  additional  licenses  under  the

maintenance-related  costs going  forward will be shared  equally among all such
licensees. Licensor shall have no obligation to (i) file or prosecute any patent
applications  or maintain any patents unless Licensee and other licensees of the
Licensed  Patent  Rights,  if any,  have agreed to fund such  activities or (ii)
conduct any  interference  or opposition  proceedings  unless Licensee and other
licensees  of the  Licensed  Patent  Rights,  if any,  have  agreed to fund such
proceedings.

                                    Licensee  may  terminate   its   obligations
hereunder to bear the cost of prosecution  and  maintenance  with respect to any
given patent  application or patent upon sixty (60) days prior written notice to
Licensor.  In such event,  (i) Licensor may, but is not  obligated to,  continue
prosecution  or  maintenance  of such  patent  application  or  patent  and (ii)
Licensee shall have no further right or license thereunder.

                                    Licensee  shall  pay any  amounts  due under

any third party  infringement  of the Licensed  Patent Rights of which  Licensee
becomes aware. Licensee has no right or authority to resolve,  abate or commence
any legal  proceedings  or take any other action in connection  with any alleged
infringement  of the Licensed  Patent Rights  without  Licensor's  prior written
consent, which consent Licensor may give or withhold in its sole discretion.

                                    Disclaimer  of   Warranties.   THE  LICENSED
PATENT RIGHTS ARE PROVIDED TO LICENSEE "AS IS." LICENSOR  MAKES NO WARRANTIES TO

domestic, or other intellectual property right of any third party;

issue  and sell to the  Purchaser,  and,  subject  to and in  reliance  upon the
representations,  warranties,  terms  and  conditions  of  this  Agreement,  the
Purchaser  agrees to purchase,  the Preferred  Shares for an aggregate  purchase
price of  $3,500,000  million.  Such  purchase  and sale  shall  take place at a
closing (the "Closing") to be held at the offices of Testa, Hurwitz & Thibeault,
LLP,  High  Street  Tower,  125  High  Street,  Boston,  Massachusetts,   02110,
immediately  prior to the  effective  time of the  Merger.  At the  Closing  the

issued  in the name of the  Purchaser,  against  delivery  to the  Company  of a


                                      -6-

amount determined by subtracting Purchaser's Cash from $35,000,000.

office a register of the Notes and shall record  therein the names and addresses

registered  holder if other than the address of the holder,  and the particulars

executors  or  administrators  or his or their  duly  appointed  attorney,  upon
surrender  therefor  for exchange as  hereinafter  provided,  accompanied  by an
instrument in writing,  in form and  execution  reasonably  satisfactory  to the
Company.  Each Note  issued  hereunder,  whether  originally  or upon  transfer,
exchange or replacement  of a Note or Notes,  shall be registered on the date of
execution  thereof by the Company and shall be dated the date to which  interest
has been paid on such Notes or Note.  The  registered  holder of a Note shall be

holder or any previous registered holder of such Note.

         3.04. TRANSFER AND EXCHANGE OF NOTES. The registered holder of any Note
or Notes may,  prior to maturity or prepayment  thereof,  surrender such Note or
Notes at the principal office of the Company for transfer or exchange.  Within a
reasonable  time after  notice to the Company  from a  registered  holder of its
intention to make such exchange and without  expense (other than transfer taxes,
if any) to such registered  holder, the Company shall issue in exchange therefor
another Note or Notes,  in such  denominations  as  requested by the  registered
holder,  for the same aggregate  principal amount as the unpaid principal amount
of the Note or Notes so  surrendered  and having the same  maturity  and rate of
interest,  containing  the same  provisions  and  subject  to the same terms and
conditions  as the  Note or Notes so  surrendered.  Each new Note  shall be made
payable to such Person or Persons,  or  registered  assigns,  as the  registered
holder of such  surrendered  Note or Notes may  designate,  and such transfer or
exchange  shall be made in such a manner  that no gain or loss of  principal  or
interest shall result therefrom.

satisfactory to the Company of the loss, theft, destruction or mutilation of any
Note and, if requested in the case of any such loss, theft or destruction,  upon
delivery  of an  indemnity  bond  or  other  agreement  or  Security  reasonably
satisfactory  to the  Company,  or,  in the  case of any such  mutilation,  upon
surrender and  cancellation  of such Note, the Company will issue a new Note, of
like  tenor and amount and dated the date to which  interest  has been paid,  in
lieu of such lost, stolen, destroyed or mutilated Note.

         3.06.  SUBORDINATION.  (a) The Company,  for itself, its successors and
assigns,  covenants and agrees,  and the Purchaser and each successor  holder of
the Notes by his or its acceptance thereof,  likewise covenants and agrees, that
notwithstanding  any other provision of this Agreement or the Notes, the payment
of the  principal  of and  interest  on  each  and  all of the  Notes  shall  be
subordinated  in right of  payment,  to the prior  payment in full of all Senior
Debt (as hereinafter  defined) at any time  outstanding.  The provisions of this
Section 3.06 shall constitute a continuing representation to all Persons who, in
reliance upon such provisions,  become the holders of or continue to hold Senior
Debt,  and such  provisions  are made for the  benefit of the  holders of Senior
Debt,  and such holders are hereby made obligees  hereunder the same as if their
names  were  written  herein  as such,  and they or any of them may  proceed  to
enforce  such  provisions  against the Company or against the holder of any Note
without the necessity of joining the Company as a party.

                  (b) Subrogation.  Subject to the payment in full of all Senior
Debt and until the Notes  shall be paid in full,  the holders of the Notes shall
be subrogated to the rights of the holders of Senior Debt to receive payments or
distributions  of assets of the Company  applicable  to the Senior Debt. No such
payments or  distributions  applicable to the Senior Debt shall,  as between the
Company and its creditors, other than the holders of Senior Debt and the holders
of the Notes,  be deemed to be a payment by the  Company to or on account of the
Notes; and for the purposes of such subrogation, no payments or distributions to
the  holders of Senior  Debt to


                                      -8-


which the holders of the Notes would be entitled  except for the  provisions  of
this Section 3.06 shall,  as between the Company and its  creditors,  other than

payment by the Company to or on account of the Senior Debt.

intended  solely for the purpose of defining the relative  rights of the holders
of the Notes,  on the one hand, and the holders of the Senior Debt, on the other
hand.  Nothing  contained in this Section 3.06 or elsewhere in this Agreement or
the Notes is intended to or shall impair, as between the Company,  its creditors
other  than the  holders of Senior  Debt,  and the  holders  of the  Notes,  the
obligation of the Company,  which is unconditional  and absolute,  to pay to the
holders of the Notes the  principal of and interest on the Notes as and when the
same shall become due and payable in accordance  with the terms  thereof,  or to
affect the  relative  rights of the  holders of the Notes and  creditors  of the
Company other than the holders of the Senior Debt, nor shall anything  herein or
therein  prevent the holder of any Note from  accepting any payment with respect
to such Note or exercising  all remedies  otherwise  permitted by applicable law
upon default under such Note,  subject to the rights, if any, under this Section
3.06 of the holders of Senior Debt in respect of cash, property or securities of
the Company received by the holders of the Notes.

institutional  lenders,  including  any extension or renewals  thereof,  whether

by its terms  subordinate  and junior to or on a parity with the Notes and which
is  permitted  hereby  at the  time it is  created  or  incurred,  and  (ii) all
guaranties by the Company which are not by their terms subordinate and junior to
or on a parity  with the Notes and which are  permitted  hereby at the time they
are  made,  of  Indebtedness  of any  of  the  Company's  Subsidiaries  if  such
Indebtedness  would have been Senior Debt  pursuant to the  provisions of clause
(i) of this  sentence had it been  Indebtedness  of the  Company.  In making any
loans which are (or the guaranties of which are) intended to be Senior Debt, the
lenders  or  purchasers  shall  be  entitled  to rely as to the fact  that  such
Indebtedness or guaranty is permitted hereby upon a certificate by the Company's
chief financial  officer  purporting to show such  Indebtedness or guaranty will
not result in the Company's  failure to comply with the provisions of Article VI
hereof as of the date of the loan or guarantee.

         3.07.  PREPAYMENT PROVISIONS.  The Company covenants and agrees that, 
so long as any of the Notes is outstanding:

                  (a) Required  Liquidity Event  Prepayments.  The Company shall
give to each holder of the Notes a notice  complying  with the  requirements  of
paragraph (c) hereof,  not less than thirty (30) days prior to the occurrence of
any Liquidity  Event,  or if the Company did not have knowledge that a Liquidity
Event would occur until less than thirty days prior thereto, then as promptly as
practicable,  but in no event more than two (2) business  days after the Company
first  acquires  knowledge  that a Liquidity  Event will occur or has  occurred,
describing in reasonable detail the facts and circumstances  giving rise thereto
and  stating  that the Company  will  prepay all,  but not less than all, of the
Notes held by each  holder.  The Company  shall,  on


                                      -9-

together with all interest accrued to the date of prepayment.

                  The term "Liquidity Event" shall mean (i) any consolidation of
the Company with or merger of the Company into another  Person or Persons or any
merger of another Person or Persons into the Company,  or any other  transaction
or series of related  transactions,  which results  directly or indirectly in an
aggregate  change in the  ownership  or  control  of more than 30% of the voting
rights of outstanding  voting equity  securities of the Company,  (ii) any sale,
lease,  mortgage,  exchange,  transfer  or other  disposition  of  assets of the
Company or its  Subsidiaries  (excluding any made in connection  with the Senior
Debt) which,  when aggregated with any sales or other  dispositions of assets of
the Company  occurring  after the date of this  Agreement,  results in the sale,
lease, mortgage, exchange, transfer or other disposition of all or substantially
all of the  assets  of the  Company  to  another  Person or  Persons,  (iii) the
acquisition by any Person,  other than James D. Norrod,  directly or indirectly,
of securities of the Company  representing more than 30% of the voting rights of
outstanding  voting equity securities of the Company,  (iv) a liquidation of the
Company, or (v) the closing of the Company's initial public offering.

                  (b) Required Prepayments Based Upon Excess Cash Flow. For each
year that the Notes are  outstanding,  the Company shall prepay,  within fifteen
(15) days after the end of  Seller's  fiscal  year  Seller,  without  penalty or
premium,  an amount of the principal  amount then outstanding on the Notes equal
to fifty  percent  (50%) of the  Excess  Cash  Flow for such  fiscal  year.  The
calculation of the amount of such  prepayment  will be reviewed by the Company's
independent  auditors in connection with the audit for the Company's fiscal year
then ended. In the event that the amount prepaid by the Company (a) is less than
the amount determined by the Company's independent  auditors,  the Company shall
within fifteen (15) days of such  determination  remit to Seller an amount equal
to such shortfall or (b) is greater than the amount  determined by the Company's
independent  auditors,  the amount of such  overpayment will be credited against
future  payments of interest  and/or  principal on the Notes.  In the event that
Seller raises an objection to the amount of such prepayment  within fifteen (15)
days after receipt by Seller of the Company's audited  financial  statements for
the fiscal year then ended,  such dispute shall be resolved by Price Waterhouse,
LLP,  or if such firm  declines to act in such  capacity,  by such other firm of
independent  nationally  recognized  accountants chosen and mutually accepted by
both parties.

                  (c) Required Prepayments Based Upon Permitted Dispositions. At
any time the Notes are  outstanding,  the Company shall prepay,  within  fifteen
(15) days after the receipt of funds,  without penalty or premium,  an amount of

the  applicable  provisions  of ERISA,  the Code and other federal or state law.
Each Plan which is  intended  to qualify  under  Section  401(a) of the Code has
received a favorable determination letter from the IRS and to the best knowledge
of the  Company,  nothing  has  occurred  which  would  cause  the  loss of such
qualification.  The  Company  and each  ERISA  Affiliate  has made all  required
contributions to any Plan subject to Section 412 of the Code, and no application
for a funding  waiver or an extension  of any  amortization  period  pursuant to
Section 412 of the Code has been made with respect to any Plan.

result in an Material Adverse Effect.  There has been no prohibited  transaction
or  violation  of the  fiduciary  responsibility  rules with respect to any Plan
which has  resulted  or could  reasonably  be  expected  to result in a Material
Adverse Effect.

neither the Company nor any ERISA Affiliate has incurred,  or reasonably expects
to incur,  any liability  (and no event has occurred  which,  with the giving of
notice  under  Section  4219 of ERISA,  would  result in such  liability)  under
Section  4201 or 4243 of ERISA with  respect to a  Multiemployer  Plan;  and (v)
neither the Company nor any ERISA  Affiliate has engaged in a  transaction  that
could be subject to Section 4069 or 4212(c) of ERISA.

all the Notes  and all  other  sums  payable  under  the  Notes  and under  this

                                                                       EXHIBIT A
                                                                       ---------
                       CLASS A REDEEMABLE PREFERRED STOCK

      1. Number of Shares.  The class of Preferred Stock designated and known as
"Class A Redeemable Preferred Stock" shall consist of 3,500 shares.

      2.  Voting.  Except as may be  otherwise  provided by law, or in Section 6
hereof, the Class A Redeemable  Preferred Stock shall be non-voting and will not
participate in any actions to be taken by the  stockholders of the  Corporation.
On  matters  that  require  a vote of the  holders  of the  Class  A  Redeemable
Preferred Stock, each share of Class A Redeemable  Preferred Stock shall entitle
the holder thereof to one vote.

      3. Dividends.  The holders of the Class A Redeemable Preferred Stock shall
be entitled to receive,  out of funds  legally  available  therefor,  cumulative
quarterly  dividends  at an  annual  rate per  share of the  Class A  Redeemable
Preferred  Stock equal to eight  percent  (8%) (such price  subject to equitable
adjustment  in the event of any stock split,  combination,  reclassification  or
other similar event), payable quarterly on the last day of September,  December,
March  and June in each  year,  the first  such  payment  to be due and  payable
December 31, 1996,  such dividends to accrue on each share of Class A Redeemable
Preferred  Stock  beginning  from the date of  original  issuance of such share,
whether or not earned or declared. Such dividends shall be cumulative so that if
such dividends in respect of any previous or current quarterly  dividend period,
at the rate  specified  above,  shall not have been paid or  declared  and a sum
sufficient  for the payment  thereof set apart,  the  deficiency  shall first be
fully paid before any dividend or other  distribution  shall be paid or declared
and set apart for the Common  Stock;  provided,  however,  that all  accrued and
unpaid  dividends,  whether or not earned or declared,  shall bear interest from
the  respective  payment date until paid at an annual rate of ten percent  (10%)
(the  "Default  Rate").  No dividend  (other than a dividend  payable  solely in
additional shares of Common Stock) may be declared or paid on or with respect to
the Common  Stock in any year  unless  the  foregoing  dividend  shall have been
declared and paid on the Class A Redeemable Preferred Stock.

      4. Liquidation. 4A. Upon any liquidation, dissolution or winding up of the
Corporation,  whether  voluntary  or  involuntary,  the holders of the shares of
Class A Redeemable Preferred Stock shall be entitled, before any distribution or
payment  is made upon any stock  ranking  on  liquidation  junior to the Class A
Redeemable  Preferred  Stock,  to be paid an amount equal to $1,000.00 per share
plus, in the case of each share,  an amount equal to any dividends  declared but
unpaid thereon,  computed to the date payment thereof is made available, and the
holders of Class A  Redeemable  Preferred  Stock  shall not be  entitled  to any
further  payment,  such  amount  payable  with  respect  to one share of Class A
Redeemable  Preferred  Stock being  sometimes  referred  to as the  "Liquidation
Preference  Payment"  and with  respect  to all  shares  of  Class A  Redeemable
Preferred  Stock  being  sometimes  referred to as the  "Liquidation  Preference
Payments."  If  upon  such  liquidation,   dissolution  or  winding  up  of  the
Corporation,  whether  voluntary or  involuntary,  the assets to be  distributed
among the holders of Class A Redeemable Preferred Stock shall be insufficient to
permit  payment to the  holders  of Class A  Redeemable  Preferred  Stock of the
amount distributable as aforesaid,  then the entire assets of the Corporation


                                      A-1


to be so distributed  shall be distributed  ratably among the holders of Class A
Redeemable Preferred Stock. Upon any such liquidation, dissolution or winding up
of the  Corporation,  after the holders of Class A  Redeemable  Preferred  Stock
shall have been paid in full the  amounts to which they shall be  entitled,  the
remaining net assets of the  Corporation  may be  distributed  to the holders of
stock ranking on liquidation  junior to the Class A Redeemable  Preferred Stock.
Written notice of such liquidation, dissolution or winding up, stating a payment
date, the amount of the Liquidation Preference Payments and the place where said
Liquidation  Preference Payments shall be payable, shall be delivered in person,
mailed by certified or registered  mail,  return receipt  requested,  or sent by
telecopier  or telex,  not less than twenty (20) days prior to the payment  date
stated therein, to the holders of record of Class A Redeemable  Preferred Stock,
such notice to be  addressed  to each such holder at its address as shown by the
records of the Corporation.  For purposes hereof, the Common Stock shall rank on
liquidation junior to the Class A Redeemable Preferred Stock.

              4B. A "Liquidity Event" is deemed to include any (1) consolidation
of the  Corporation  with or merger of the  Corporation  into another  person or
persons or any merger of another  person or persons into the  Corporation or any
other  transaction or series of related  transactions  which results directly or
indirectly  in an  aggregate  change in ownership or control of more than 30% of
the voting rights of outstanding  voting equity  securities of the  Corporation;
(2) sale,  lease,  mortgage,  exchange,  transfer  or other  disposal  of all or
substantially  all of the assets of the Corporation to another person or persons
shall  be  deemed  to  be a  liquidation,  dissolution  or  winding  up  of  the
Corporation within the meaning of the provisions of this paragraph 4; or (3) the
acquisition  by any person or persons,  other than James D. Norrod,  directly or
indirectly,  of securities of the Corporation  representing more than 30% of the
voting rights of outstanding voting equity securities of the Corporation.

              4C. In any of such events  specified  in  subparagraph  4B, if the
consideration  received by the Corporation is other than cash, its value will be
deemed its fair market value. Any securities shall be valued as follows:

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

                               (i) If traded on a securities exchange or through
      the Nasdaq National Market, the value shall be deemed to be the average of
      the closing  prices of the securities on such exchange over the thirty-day
      period ending three (3) days prior to the closing;

                               (ii) If  actively  traded  over-the-counter,  the
      value  shall be deemed to be the average of the closing bid or sale prices
      (whichever is applicable) over the thirty-day period ending three (3) days
      prior to the closing; and

                               (iii) If there is no active  public  market,  the
      value shall be the fair market value  thereof,  as mutually  determined by
      the Corporation and the holders of at least a majority of the voting power
      of all then outstanding shares of Class A Redeemable Preferred Stock.


                                      A-2


                     (2) The  method  of  valuation  of  securities  subject  to
investment  letter  or other  restrictions  on free  marketability  (other  than
restrictions  arising solely by virtue of a shareholder's status as an affiliate
or former  affiliate)  shall be to make an appropriate  discount from the market
value determined as above in 4C(1)(i),  (ii) or (iii) to reflect the approximate
fair market value thereof,  as mutually  determined by the  Corporation  and the
holders  of at least a  majority  of the  voting  power of all then  outstanding
shares of such Class A Redeemable Preferred Stock.

                     (3) In the event the  requirements of subsections 4B and 4C
are not complied with, the Corporation shall forthwith either:

                               (i) cause such closing to be postponed until such
time as the requirements of this paragraph 4 have been complied with; or

                               (ii) cancel such transaction,  in which event the
rights,  preferences  and  privileges  of the  holders  of  Class  A  Redeemable
Preferred Stock shall revert to and be the same as such rights,  preferences and
privileges  existing  immediately prior to the date of the first notice referred
to in subsection 4(A) hereof.

      5. Redemption.  The shares of Class A Redeemable  Preferred Stock shall be
redeemed as follows:

              5A. Full Mandatory  Redemption.  The Corporation shall redeem from
each holder of shares of Class A Redeemable Preferred Stock all of the shares of
Class A  Redeemable  Preferred  Stock held by such  holder on the earlier of the
following events (the "Mandatory Redemption Date"):

                     (1) September 30, 2001; or

                     (2) thirty (30) days after the closing of the Corporation's
initial public offering of Common Stock registered under the Securities Act of 
1933, as amended.

              5B. Optional  Redemption.  The Corporation may, at any time at its
sole  discretion,  redeem  from each  holder  of  shares  of Class A  Redeemable
Preferred  Stock,  all or less  than all of the  shares  of  Class A  Redeemable
Preferred Stock held by each such holder.  If the Corporation  shall redeem less
than all of each  holder's  shares of Class A Redeemable  Preferred  Stock,  the
Corporation  shall  redeem an amount of each  holder's  such  shares pro rata in
relation to all the then  outstanding  Class A Redeemable  Preferred  Stock. The
date of any such optional  redemption by the Corporation shall be referred to as
an "Optional Redemption Date."

              5C.  Partial Mandatory Redemption.

              (1) Partial  Redemption  Based on Excess Cash Flow. If at any time
the Secured  Subordinated  Notes of the Corporation issued pursuant to a certain
Asset Purchase  Agreement


                                      A-3


dated as of July 21, 1996 between Telebit  (Newco) Inc. and Telebit  Corporation
(the "Asset  Agreement") are not  outstanding,  then while any shares of Class A
Redeemable Preferred Stock remain outstanding,  with fifteen (15) days after the
end of the Corporation's fiscal year, the Corporation shall redeem the number of
whole shares (rounding downward) of the Class A Redeemable Preferred Stock equal
to fifty  percent  (50%)  of the  Excess  Cash  Flow (as  defined  in the  Asset
Agreement  )  for  such  fiscal  year  divided  by  the  Redemption  Price.  The
calculation  of the  number  of  shares of Class A  Redeemable  Preferred  Stock
redeemed  and  the  Corporation's  Excess  Cash  Flow  will be  reviewed  by the
Corporation's   independent  auditors  in  connection  with  the  audit  of  the
Corporation's  fiscal  year then  ended.  In the event that the Excess Cash Flow
amount  used by the  Corporation  to  calculate  the number of shares of Class A
Redeemable Preferred Stock to be redeemed under paragraph 5C(1) is less than the
Excess Cash Flow amount  determined by the Corporation's  independent  auditors,
the Corporation shall within fifteen (15) days of such determination  redeem the
number of whole shares (rounding downward) of Class A Redeemable Preferred Stock
equal to a number:

                     (a) the  numerator  of which  shall be the Excess Cash Flow
      amount determined by the Corporation's  independent auditors in connection
      with the audit of the Corporation's fiscal year then ended less the Excess
      Cash Flow amount determined by the Corporation, and

                     (b) the denominator of which shall be the Redemption Price.

In the  event  that the  Excess  Cash Flow  amount  used by the  Corporation  to
calculate  the  number  of shares of Class A  Redeemable  Preferred  Stock to be
redeemed  under  paragraph  5C(1) is greater  than the Excess  Cash Flow  amount
determined by the  Corporation's  independent  auditors,  the Corporation  shall
reduce the amount of the  Corporation's  next succeeding  redemption  obligation
under 5C(1) by a whole number (rounding downward):

                     (a) the  numerator  of which  shall be the Excess Cash Flow
      amount  determined  by the  Corporation  less the Excess  Cash Flow amount
      determined by the  Corporation's  independent  auditors in connection with
      the audit of the Corporation's fiscal year then ended, and

                     (b) the denominator of which shall be the Redemption Price.

              (2) Partial Redemption Based on Permitted Dispositions.  If at any
time the Secured  Subordinated  Notes of the Corporation  issued pursuant to the
Asset Agreement are not outstanding, then while any shares of Class A Redeemable
Preferred Stock remain  outstanding,  within fifteen (15) days after the receipt
of funds,  the  Corporation  shall redeem the number of whole  shares  (rounding
downward) of Class A Redeemable  Preferred Stock equal to the amount of proceeds
received  by  the  Corporation  from  any  sale,  assignment,   lease  or  other
disposition of or voluntary parting of control of (whether in one transaction or
in a series of  transactions)  a substantial  portion of the assets (whether now
owned or hereinafter  acquired) of the  Corporation  or any of its  subsidiaries
(each a "Permitted  Disposition")  which, during any fiscal year when taken with
all other Permitted  Dispositions by the  Corporation,  exceeds in the aggregate


                                      A-4



$500,000,  less the  applicable  costs and taxes payable by the  Corporation  in
connection therewith divided by the Redemption Price.

              (3) Partial Redemption Based on Additional  Financings.  If at any
time the Secured  Subordinated  Notes of the Corporation  issued pursuant to the
Asset Agreement are not outstanding, then while any shares of Class A Redeemable
Preferred Stock remain outstanding, within (15) days after the after the receipt
of funds,  the  Corporation  shall redeem the number of whole  shares  (rounding
downward) of Class A Redeemable  Preferred Stock equal to the amount of proceeds
received by the  Corporation  through (a) any  issuance by the Company of voting
equity  securities,  other than in the  Corporation's  initial  public  offering
which, in the aggregate,  exceed $5 million in any year or (b) the incurrence by
the Corporation or its  subsidiaries of any  Indebtedness for borrowed money (as
defined in a certain  Preferred Stock Purchase and Noteholder  Rights  Agreement
dated as of July 21, 1996 between Telebit  (Newco) Inc. and Telebit  Corporation
(the  "Preferred  Stock Purchase and  Noteholder  Rights  Agreement"),  which is
subordinate  to the Senior Debt (as defined in the Preferred  Stock Purchase and
Noteholder  Rights  Agreement)  (each  an  "Additional  Financing"),   less  the
applicable  costs and taxes payable by the  Corporation in connection  therewith
divided by the Redemption Price.

              The  date  of  any  such  partial  mandatory   redemption  by  the
Corporation shall be referred to as a "Partial  Mandatory  Redemption Date." The
Mandatory  Redemption  Date,  the  Optional  Redemption  Date  and  the  Partial
Mandatory  Redemption  Date are  sometimes  referred to herein as a  "Redemption
Date."

              5D. Redemption Price and Payment. The Class A Redeemable Preferred
Stock to be redeemed on any Redemption Date shall be redeemed by paying for each
share in cash an amount equal to $1,000.00  per share plus,  in the case of each
share, an amount equal to any dividends declared but unpaid thereon, computed to
the applicable Redemption Date, such amount being referred to as the "Redemption
Price." Such payment shall be made in full on the applicable  Redemption Date to
the holders entitled thereto.

              5E. Redemption  Mechanics.  At least twenty (20) but not more than
thirty  (30)  days  prior  to the  any  Redemption  Date,  written  notice  (the
"Redemption  Notice")  shall be given by the  Corporation by delivery in person,
certified or registered mail, return receipt requested,  telecopier or telex, to
each  holder  of record  (at the  close of  business  on the  business  day next
preceding the day on which the Redemption  Notice is given) of shares of Class A
Redeemable   Preferred  Stock  notifying  such  holder  of  the  redemption  and
specifying the Redemption  Price,  the applicable  Redemption Date and the place
where said  Redemption  Price shall be payable.  The Redemption  Notice shall be
addressed  to  each  holder  at his  address  as  shown  by the  records  of the
Corporation.  From and after the close of business on the applicable  Redemption
Date,  unless  there shall have been a default in the payment of the  Redemption
Price,  all rights of holders of shares of Class A  Redeemable  Preferred  Stock
(except the right to receive the  Redemption  Price) shall cease with respect to
such shares, and such shares shall not thereafter be transferred on the books of
the  Corporation or be deemed to be outstanding for any purpose  whatsoever.  If
the funds of the Corporation legally available for redemption of shares of Class
A Redeemable Preferred Stock on the applicable  Redemption Date are insufficient
to redeem the total number of 


                                      A-5


outstanding shares of Class A Redeemable  Preferred Stock, the holders of shares
of Class A Redeemable  Preferred  Stock shall share ratably in any funds legally
available for  redemption  of such shares  according to the  respective  amounts
which would be payable  with  respect to the full number of shares owned by them
if all such  outstanding  shares were  redeemed  in full.  The shares of Class A
Redeemable Preferred Stock not redeemed shall remain outstanding and entitled to
all  rights  and  preferences  provided  herein.  At any  time  thereafter  when
additional funds of the Corporation are legally  available for the redemption of
such shares of Class A Redeemable  Preferred Stock,  such funds will be used, at
the end of the next  succeeding  fiscal  quarter,  to redeem the balance of such
shares, or such portion thereof for which funds are then legally  available,  on
the basis set forth above.

              5F.  Redeemed or  Otherwise  Acquired  Shares to be  Retired.  Any
shares of Class A Redeemable Preferred Stock redeemed pursuant to this paragraph
5 or otherwise  acquired by the  Corporation in any manner  whatsoever  shall be
canceled and shall not under any circumstances be reissued;  and the Corporation
may from time to time take such appropriate corporate action as may be necessary
to reduce  accordingly  the number of  authorized  shares of Class A  Redeemable
Preferred Stock.

      6.  Protective  Provisions.  Subject to the rights of series of  preferred
stock which may from time to time come into existence,  so long as any shares of
Class A Redeemable  Preferred Stock are outstanding,  the 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 then  outstanding  shares of
Class A Redeemable Preferred Stock:

              6A. alter or change the rights,  preferences  or privileges of the
shares  of Class A  Redeemable  Preferred  Stock so as to affect  adversely  the
shares; or

              6B.  authorize or issue,  or obligate  itself to issue,  any other
equity  security,  including any other security  convertible into or exercisable
for any equity security having a preference over, or being on a parity with, the
Class  A  Redeemable   Preferred   Stock  with  respect  to  dividends  or  upon
liquidation.

for at least twenty (20) days' written  cancellation notice to Secured Party. If
and when requested by the Secured Party,  the Debtor shall furnish Secured Party
with certificates or other evidence  satisfactory to Secured Party of compliance
with the foregoing  insurance  provision and the Secured Party may act either in
its name or as attorney for the Debtor (for that purpose by these  presents duly
authorized  and appointed  with full power of  substitution  and  revocation) in
obtaining,  adjusting,  settling and cancelling such insurance and endorsing any
drafts in payment of any loss.

         (F) The Debtor will upon  request  made by the Secured  Party render to
the Secured  Party a list of all  Accounts  assigned  hereunder  and a statement
indicating the total dollar amount of the Accounts then outstanding.

         (G) The only offices  where the Debtor  keeps  records  concerning  any
Accounts  are listed on  Schedule  B and the Debtor  will not remove any of such
records from said offices without written consent of the Secured Party.

         (H) The Debtor will keep its  Collateral  free from any  adverse  lien,
security interest or encumbrances except the Permitted Encumbrances, if any, and
will appear in and defend any action or suit which may affect the Debtor's title
to, or the interests of the Secured Party in the Collateral.  The Debtor will at
all times keep accurate and complete  records of its  Accounts,  and the Secured
Party or any of its  agents  shall have the right at


                                      C-3


reasonable  times and upon prior  notice,  to  inspect  the  Debtor's  books and
records  relating  to said  Accounts or to any other  transactions  to which the
Debtor is a party and from which an  Account  might  arise and to make  extracts
from said books and  records.  The Debtor shall  immediately  notify the Secured
Party of any event causing  material loss or depreciation in value of any of its
Accounts and the amount of such loss or depreciation.

         (I) If any of a  Debtor's  Accounts  arise  out of  contracts  with the
United States or any department,  agency or instrumentality  thereof, the Debtor
will  immediately  notify the Secured  Party thereof in writing and will execute
any  instruments  and take any steps required by the Secured Party in order that
all monies due and to become due under such  contracts  shall be assigned to the
Secured  Party and notice  thereof  given to the  government  under the  Federal
Assignment of Claims Act.

         (J) Subsequent to the  occurrence of any Event of Default,  if any of a
Debtor's Accounts should be evidenced by promissory notes,  trade acceptances or
other instruments for the payment of money, the Debtor will immediately  deliver
same to the Secured Party,  appropriately  endorsed to the Secured Party's order
and,  regardless  of the form of such  endorsement,  such Debtor  hereby  waives
presentment,  demand or notice of any kind with respect thereto.  This Agreement
may, but need not be  supplemented  by separate  assignments  of Accounts to the
Secured  Party  and if such  assignments  are  given  the  rights  and  security
interests  given  thereby  shall be in addition to and not in  limitation of the
rights and security interests given by this Agreement.

         (K) The Debtor  will pay  promptly  when due all taxes and  assessments
upon its  Collateral or for its use or operation or upon this  Agreement or upon
any note or notes secured hereby. In its sole discretion, the Secured Party may:
(i)  discharge  taxes and liens  levied  or placed on  Collateral;  (ii) pay for
insurance thereon or the maintenance and preservation  thereof;  or (iii) if the
Debtor  shall fail to make  required  deposits  in respect  of  F.I.C.A.  or any
withholding taxes, make such deposits or pay such taxes, in whole or in part, or
set up such reserves as the Secured Party in its sole  discretion deem necessary
in respect of the Debtor's liability therefor.  Any amount so paid, deposited or
reserved for shall constitute a loan for all purposes hereunder,  and the Debtor
promises  to repay the  Secured  Party such  amounts  upon the  Secured  Party's
demand.  Nothing  herein shall be deemed to obligate the Secured Party to do any
of the  foregoing and the making of any one or more such  payments;  deposits or
reserves  shall not  constitute  an agreement  by the Secured  Party to take any
further  or  similar  action  or a  waiver  of any  right of the  Secured  Party
hereunder.

         (L) The Debtor will keep its  Collateral at all times in good order and
repair,  reasonable wear and tear excepted,  and will make necessary renewals of
and replacements to the same with goods of equal value and serviceability,  free
of  all  liens,   security   interests  and  encumbrances,   which  goods  shall
automatically  become  subject to this  Agreement.  The Debtor will not abandon,
other than in the ordinary course of business, any Collateral.


                                      C-4



         (M) The Debtor  will,  at the end of each month after the date  hereof,
provide the Secured Party with written  reports  detailing any new  intellectual
property  assets in form  sufficient for filing of a security  interest with all
applicable governmental agencies.

II.      ADDITIONAL RIGHTS AND ASSURANCES.

         (A) At the Secured  Party's  request,  the Debtor at its  expense  will
promptly  and duly  execute  and  deliver  such  documents  (including,  without
limitation,  any stock pledge and other security  agreements) and assurances and
take such actions as may be  necessary or desirable or as the Secured  Party may
request in order to correct any defect,  error or omission which may at any time
be  discovered or to more  effectively  carry out the intent and purpose of this
Agreement and to  establish,  perfect and protect the Secured  Party's  security
interest, rights and remedies created or intended to be created hereunder.

         (B) The Secured  Party will at any time  following an  occurrence of an
Event of Default  hereunder  have the right to take  physical  possession of the
Collateral and to maintain such possession on the Debtor's premises or to remove
the Collateral or any part thereof to such other places as the Secured Party may
desire.  If the Secured Party exercises such right, the Debtor shall at its sole
expense upon the Secured Party's request assemble the same and make it available
to the Secured Party at a place  reasonably  convenient to the Secured Party. If
any Inventory is in the  possession or control of any of the Debtor's  agents or
processors, the Debtor shall, at the Secured Party's request, notify them of the
Secured Party's  security  interest therein and, at the Secured Party's request,
instruct  them to hold the same for the Secured  Party's  account and subject to
the Secured Party's instructions.

         (C) The Secured  Party may at any time after an occurrence of a default
or an Event of Default (i) in its own name or in the name of others  communicate
with  account  debtors  in order to  verify  with  them to the  Secured  Party's
satisfaction the existence,  amount and terms of any Accounts and the absence of
any reductions,  discounts,  defenses or offsets with respect  thereto,  or (ii)
notify  account  debtors that  Collateral has been assigned to the Secured Party
and that payments by such debtors  shall be made directly to the Secured  Party.
At the Secured Party's  request,  the Debtor will notify any or all such debtors
of such assignment, give instruction and/or indicate on billings to such debtors
that their  Accounts  shall be paid to the  Secured  Party  and/or  supply  such
debtors with a copy of this Agreement.

         (D) Subsequent to the  occurrence of any Event of Default,  the Secured
Party shall have full power, in its own name or that of the Debtor,  to collect,
endorse,  compromise,  settle,  sell or  otherwise  deal  with any or all of the
Collateral or proceeds  thereof.  Subsequent  to the  occurrence of any Event of
Default,  the Debtor  agrees upon  request of the  Secured  Party to appoint any
officer or agent of the Secured Party as true and lawful attorney-in-fact,  with
power of substitution, to endorse the name of the Debtor or any of its officers,
trustees or agents upon any Accounts,  notes,  checks,  drafts, money orders, or
other  instruments  of  payment  (including  under any  policy of  insurance  on


                                      C-5


Collateral) or Collateral  that may come into possession of the Secured Party in
full or part payment of any amounts owing to Secured Party;  to sign and endorse
the name of the  Debtor or any of its  officers,  trustees  or  agents  upon any
invoice, freight or express bill, bill of lading, storage or warehouse receipts,
drafts against  debtors,  assignments,  verifications  and notices in connection
with  Accounts,  and any  instruments  or documents  relating  thereto or to the
Debtor's rights therein; to give written notice to such offices and officials of
the United States Postal  Service to effect such change or changes of address so
that all mail  addressed to the Debtor may be delivered  directly to the Secured
Party;  to take any and all other actions  necessary or  appropriate to collect,
compromise,  settle, sell or otherwise deal with any or all of the Collateral or
proceeds thereof; and to obtain, adjust, settle and cancel any insurance; hereby
granting to each said  attorney-in-fact  or his substitute  full power to do any
and all things  necessary or appropriate to be done in and about the premises as
fully and effectually as the Debtor might or could do, and hereby  ratifying all
that any said  attorney-in-fact  or his substitute shall lawfully do or cause to
be done by virtue hereof.

         (E) The Debtor hereby assigns to the Secured Party all sums,  including
without  limitation  return of premiums,  which may become payable under any and
all of such Debtor's  policies of insurance and directs each  insurance  company
issuing any such policy to make payment which would  otherwise be due thereunder
to the Debtor directly to the Secured Party.

         (F) To the extent  permitted by Debtor's lease on any premises or place
of  business,  the  Debtor  hereby  grants  to  the  Secured  Party,  for a term
commencing on the date of the  occurrence of any Event of Default and continuing
as long as any of the Obligations remain  outstanding,  at a rental of $1.00 for
such  entire  term,  the right to the use of all  premises or places of business
which such  Debtor now or  hereafter  may have and where any  Collateral  may be
located for the purpose of protecting or enforcing the Secured Party's rights to
the Collateral.

         (G) In the event of the sale,  exchange  or  disposition  of any of the
Collateral (other than finished goods in the ordinary course of business) or any
interest  therein  (and no such sale,  exchange or other  disposition  is hereby
authorized  or  consented  to),  the Secured  Party's  security  interest  shall
nevertheless  continue in such  Collateral  (including  without  limitation  all
proceeds,  cash and  non-cash)  notwithstanding  such  sale,  exchange  or other
disposition;  and the Secured  Party's receipt of any such proceeds shall not be
deemed or  construed  to be an  authorization  of or  consent  to any such sale,
exchange or other disposition.

         (H) Any and all  instruments,  documents,  policies and certificates of
insurance,  securities, goods, accounts, chooses in action, general intangibles,
chattel paper, cash,  property and the proceeds thereof (whether or not the same
are  Collateral or proceeds  thereof) owned by the Debtor or in which the Debtor
has an interest, which now or hereafter are at any time in possession or control
of the Secured Party or any affiliate of the Secured Party or in transit by mail
or carrier to or from the Secured Party or such


                                      C-6


affiliate or in the possession of any third party acting in its behalf,  without
regard to whether  the  Secured  Party or such  affiliate  received  the same in
pledge, for safekeeping, as agent for collection or transmission or otherwise or
had conditionally  released the same, shall constitute  security for Obligations
and may be applied at any time to Obligations which are then owing,  whether due
or not due.

         (I)  A  carbon,  photographic,  or  other  reproduction  of a  security
agreement or a financing statement is sufficient as a financing statement to the
extent permitted under applicable law.

         (J) License.  For the purpose of enabling the Secured Party to exercise
its rights and remedies  under this  Agreement,  the Debtor hereby grants to the
Secured Party an irrevocable,  non-exclusive and assignable license (exercisable
without payment or royalty or other  compensation to the Debtor) to use, license
or sublicense any intellectual property Collateral upon any Event of Default (as
defined below).

III.     EVENTS OF DEFAULT.

         The Debtor shall be in default under this  Agreement upon the happening
of any of the following events or conditions  (individually  and collectively an
"Event of Default"):

         (A)  Failure  by the  Debtor to observe  or  perform  any  covenant  or
agreement referred to herein and, if no other grace or cure period is applicable
thereto, the continuance of such failure for five (5) business days;

         (B) Sale,  transfer or assignment of any of the  Collateral  (including
via an assignment of transfer of any interest of the Debtor) (except the sale of
inventory  in the  ordinary  course of business  and sales  permitted by Section
6.02(d) and (e) of the Purchase  Agreement);  loss, theft, or substantial damage
or  destruction  of any of the  Collateral  which is not  fully  and  adequately
insured against as hereinbefore provided; or

         (C) An Event of Default (as defined in the Purchase  Agreement or under
any of the documents  referred to therein) shall have occurred and is continuing
and such Event of Default has not been annulled.

IV.      REMEDIES.

         (A)      If an Event of Default occurs:

                           (1) The Secured  Party may  declare  all  obligations
                  secured  hereby  to be  immediately  due and  payable  without
                  presentment,  demand, protest or other notice of any kind, all
                  of which are hereby expressly waived.


                                      C-7


                           (2) The Secured Party may exercise and shall have any
                  and all rights and remedies  accorded it by the  Massachusetts
                  Uniform  Commercial  Code,  the  Uniform  Commercial  Code  as
                  adopted in such state  whose laws  govern the  disposition  of
                  certain   Collateral  or  under  other   applicable  law.  The
                  requirement  of  reasonable  notice  shall be met,  if  notice
                  containing   such   information   as  may  be  required  under
                  applicable law is mailed,  postage  prepaid,  to the Debtor or
                  other  person   entitled   thereto  at  least  ten  (10)  days
                  (including  non-business  days)  before  the  time  of sale or
                  disposition  of the  Collateral.  The Debtor  shall pay to the
                  Secured  Party  on  demand  any  and all  expenses,  including
                  reasonable  legal  expenses and  reasonable  attorney's  fees,
                  incurred  or  paid  the  Secured   Party  in   administrating,
                  protecting  or  enforcing  any  rights  of the  Secured  Party
                  hereunder,  including  its  right  to take  possession  of the
                  Collateral, storing and disposing of the same or in collecting
                  the proceeds thereof.

         (B) The Debtor  understands  and agrees the Secured  Party may exercise
its  rights  hereunder  without  affording  the  Debtor  an  opportunity  for  a
preseizure  hearing  before  the  Secured  Party,  through  judicial  process or
otherwise, takes possession of the Collateral upon the occurrence of an Event of
Default,  and the Debtor expressly waives its  constitutional  right, if any, to
such prior hearing.

         (C)  No  delay  in  accelerating  the  maturity  of any  obligation  as
aforesaid  or in taking any other action with respect to any Event of Default or
in exercising any rights with respect to the  Collateral  such affect the rights
of the Secured  Party later to take such action  with  respect  thereto,  and no
waiver as to one Event of Default shall affect rights as to any other default.

V.       POWER OF ATTORNEY

         The Debtor  hereby  designates  and appoints the Secured Party its true
and lawful  attorney with full power of  substitution  in its own name or in the
name of such  Debtor,  to upon an Event of Default,  demand,  collect,  receive,
receipt for, sue for, compound and give acquittance for, any and all amounts due
and to become due on the  Accounts and to endorse the name of such Debtor on all
commercial paper given in payment or part-payment  thereof and in its reasonable
discretion  to file any claim or take any other action  which the Secured  Party
may reasonably deem necessary or appropriate to protect and preserve and realize
upon the  security  interest of the  Secured  Party in the  Accounts,  the other
Collateral or the proceeds thereof. Upon any Event of Default, The Secured Party
shall also have the right to (i) open all mail  addressed  to the  Debtor;  (ii)
change the Post Office box or mailing  address of the Debtor;  and (iii) use the
Debtor's stationery and billing forms or facsimiles thereof,  for the purpose of
collecting Accounts and realizing upon the other Collateral.


                                      C-8



VI.      INDEMNIFICATION

         The  Debtor  hereby  agrees  to  indemnify  the  Secured  Party and its
directors,  officers,  employees,  agents,  counsel and other  advisors (each an
"Indemnified Person"),  agents, counsel and other advisors (each an "Indemnified
Person") against,  and hold each of them harmless from, any and all liabilities,
obligations,  losses, claims, damages,  penalties,  actions,  judgments,  suits,
costs, expenses or disbursements of any kind or nature whatsoever, including the
reasonable fees and disbursements of counsel to an Indemnified Person (including
allocated costs of internal  counsel),  which may be imposed on, incurred by, or
asserted against any Indemnified  Person,  in any way relating to or arising out
of this Agreement or the transactions contemplated hereby or any action taken or
omitted to be taken by it hereunder (the "Indemnified  Liabilities").  If and to
the  extent  that  the  foregoing   indemnification   is  for  any  reason  held
unenforceable, the Debtor agrees to make the maximum contribution to the payment
and  satisfaction  of each of the Indemnified  Liabilities  which is permissible
under  applicable  law.  This  indemnity  shall  survive   termination  of  this
Agreement.

VII.     MISCELLANEOUS.

         (A) The Debtor waives,  to the fullest extent permitted by law, (i) any
right or redemption with respect to the Collateral, whether before or after sale
hereunder,  and all rights,  if any, of  marshalling  of the Collateral or other
collateral  or  security  for the  Obligations;  (ii) any right to  require  the
Secured  Party (A) to proceed  against  any  Person,  (B) to  exhaust  any other
collateral or security for any of the  Obligations,  (C) to pursue any remedy in
the Secured Party's power, or (D) to make or give any presentments,  demands for
performances,  notices  of  nonperformance,  protests,  notices of  protests  or
notices of  dishonor in  connection  with any of the  Collateral;  and (iii) all
claims,  damages,  and  demands  against the  Secured  Party  arising out of the
repossession,  retention, sale or application of the proceeds of any sale of the
Collateral.

         (B) In case any one or more of the provisions  contained  herein should
be invalid,  illegal or unenforceable in any respect, the validity,  legality or
enforceability of the remaining provisions contained herein shall not in any way
be affected or impaired thereby.

         (C) All  rights  of the  Secured  Party  hereunder  shall  inure to the
benefit of its successors and assigns;  and all  obligations of the Debtor shall
bind the  successors  or  assigns  of the  Debtor.  All the  provisions  of this
Agreement  shall be construed by and  administered  in accordance with the local
laws of the Commonwealth of Massachusetts. This Agreement shall become effective
when it is signed by the Debtor.  The Debtor  acknowledges  receipt of a copy of
this Agreement.

         (D) In the absence of gross negligence or willful  misconduct,  neither
the Secured Party nor any  attorney-in-fact  appointed hereunder shall be liable
to the Debtor 


                                      C-9



or any other person for any act or omission, any mistake of fact or any error of
judgment in exercising any right or remedy granted herein.

         (E) This Agreement shall be terminated and the transaction contemplated
hereby  prior to the  Closing  (as  defined in the  Purchase  Agreement)  if the
Purchase  Agreement is terminated in accordance  with the  provisions  contained
therein.

                              EMPLOYMENT AGREEMENT


         This  Employment  Agreement  dated as of July 21, 1996,  by and between
James  D.  Norrod  (the   "Employee")  and  Telebit  (Newco)  Inc.,  a  Delaware
corporation (the "Company").

         For good and valuable  consideration,  the receipt and  sufficiency  of
which is hereby  acknowledged,  and in consideration of the mutual covenants and
obligations contained in this Agreement, the parties agree as follows:

         1.  Position and  Responsibilities.  During the term of the  Employee's
employment with the Company, the Employee shall serve as Chief Executive Officer
and President of the Company, and shall exercise such powers and comply with and
perform such duties in  connection  with the business and affairs of the Company
as may from time to time be  assigned  to him by the board of  directors  of the
Company (the "Board").  The Employee agrees to devote  substantially  all of his
business  time,  attention and services to the diligent,  faithful and competent
discharge of his duties hereunder.

         2. Compensation: Salary, Bonuses and Other Benefits. During the term of
the Employee's  employment with the Company,  the Company shall pay the Employee
the following compensation:

                  (A) Salary. In consideration of the services to be rendered by
the Employee to the Company,  during the term hereof,  the Company  shall pay to
the Employee a salary at the rate of $247,500 per annum,  or such greater amount
as may be  determined  from  time  to  time  by the  Board  or the  Compensation
Committee thereof. Such salary shall be payable in conformity with the Company's
customary  practices  for  employee  compensation  as such  practices  shall  be
modified from time to time.  Salary  payments shall be subject to all applicable
federal and state  withholding,  payroll and other taxes. The Employee's  salary
may not be reduced at any time without his prior written consent.

                  (B)      Annual and Quarterly Bonuses.

         bonuses of up to $26,100 for each fiscal  quarter (the  "Quarterly  MBO
         Bonus") (pro-rated for partial fiscal quarters),  based upon (i) in the
         case of the annual MBO Bonus his performance (as reasonably  determined
         by the Employee and the  Compensation  Committee)  as measured  against
         annual  objectives  established  by the Board  (such  objectives  to be
         established  and a copy  thereof to be  delivered  to the  Employee  by
         January 31 of each applicable  fiscal year) and (ii) in the case of the
         Quarterly MBO Bonus the attainment by the Company of certain  quarterly
         net  income  targets  established  by the  Board  and set  forth in the
         Company's  annual  operating  budget.


                                      E-1


         The bonus payments  under this Section  2(B)(1) shall be subject to all
         applicable federal and state withholding, payroll and other taxes.

                           (2) Pursuant to the Company's Performance Bonus Plan,
         the Employee shall be eligible to receive an additional quarterly bonus
         equal to 2 percent of the  Employee's  Quarterly  MBO Bonus for every 1
         percent increase in the Company's quarterly net income in excess of the
         quarterly net income targets  established by the Board and set forth in
         the Company's annual operating  budget.  The aggregate  quarterly bonus
         payable to the Employee pursuant to the Performance Bonus Plan shall be
         limited to twice the Employee's Quarterly MBO Bonus. The bonus payments
         under this Section  2(B)(2) shall be subject to all applicable  federal
         and state withholding, payroll and other taxes.

                  (C)      Fringe Benefits.

                           (1) The employee will be entitled to receive benefits
         substantially  equivalent  to those  he  received  as  Chief  Executive
         Officer of Telebit Corporation, a California corporation.

                           (2) In addition to the  foregoing,  the Company shall
         provide  the  Employee  with a monthly  automobile  allowance  of $750,
         subject to all applicable  federal and state  withholding,  payroll and
         other taxes.

                  (D)      Relocation Expenses.

                           (1) In the event the  Employee  is  requested  by the
         Board to  relocate  in order to perform  the  services  hereunder  to a
         location more than 25 miles from Chelmsford, Massachusetts, the Company
         shall  reimburse or pay up to an amount of $100,000 for the  Employee's
         documented  out-of-pocket  expenses  incurred in  connection  with such
         relocation.  Such expenses shall include:  (i) expenses  related to the
         selling of the Employee's  prior residence,  including  brokerage fees,
         closing costs, deed preparation, transfer taxes, legal fees and loss of
         equity  due  to  relocation;   (ii)  expenses  related  to  moving  all
         furnishings to new residence;  (iii)  transaction costs associated with

         reasonable documentation therefor by the Employee.

                           (2) In addition to the  foregoing,  the Company shall
         pay  to  the  Employee  such  additional   amounts  as  are  reasonably
         determined  to be necessary  to reimburse  the Employee for any and all
         federal and state taxes that the Employee shall be required to pay as a
         result  of the  payments  made by the  Company  to or for the  Employee
         pursuant to Section 2(D)(1) above or pursuant to this Section  2(D)(2),
         after  taking  into  account  the  tax  benefit  to the  Employee  from
         incurring any of the expenses described in Section 2(D)(1) above.


                                      E-2


         3. Term. This Agreement shall become effective upon the consummation of
the asset purchase  contemplated  by the Asset Purchase  Agreement dated of even
date  herewith  between  the  Company  and  Telebit  Corporation,  a  California
corporation (the "Effective  Date"), and unless sooner terminated as hereinafter
provided,  shall continue until the third anniversary of the Effective Date (the
"Scheduled Termination Date"). Thereafter,  unless sooner terminated as provided
herein,  this  Agreement  shall  automatically  extend for  subsequent  one year
periods and the  provisions  hereof  shall  remain  applicable  for each of such
subsequent periods.

         4.       Termination.

                  (A) The Employee may  terminate his  employment  hereunder for
any reason at any time upon at least thirty (30) days prior written  notice.  In
the event the Employee  terminates  his  employment,  the Employee shall receive
accrued but unpaid salary  through the last day of  employment  but shall not be
entitled to any bonus, severance or other termination benefits.

                  (B) The Company may terminate Employee's  employment hereunder
at any time with or without notice, and with or without cause, with no liability
whatsoever with respect to such termination except for accrued but unpaid salary
existing  on the date of  termination;  provided,  however,  that if the Company
terminates  Employee after the end of any fiscal period and any bonus or bonuses
with  respect to such fiscal  period  pursuant to Section 2(B) have not yet been
paid,  then the Company's  obligation,  if any, to pay the bonus or bonuses with
respect to such fiscal period shall survive the  termination  of the  Employee's
employment;  and provided,  further, however, that if the Company terminates the
Employee's  employment  without  "just cause" or the  Employee's  employment  is
terminated  by the  Company  within  six  months  before or after a  "change  of
control",  the Company  shall  provide the  Employee  with  severance  benefits,
payable as a lump sum, a series of installments or as salary continuation at the
Company's  election,  equal to the  Employee's  then  current  salary and fringe
benefits for the period between the date of termination and the later of (i) the
Scheduled Termination Date or (ii) one year from the date of termination.

                  (C)  For  purposes   hereof,   "just  cause"  shall  mean  (i)
deliberate dishonesty, (ii) conviction of a crime involving moral turpitude, and
(iii) willful  failure to perform any lawful duties  assigned to the Employee by
the Board.  The Employee shall be deemed to have been  terminated by the Company
without  "just  cause" if (a) there is a material  reduction by the Board in the
responsibility  or authority of the Employee,  with the result that the Employee
does not have the responsibility and authority  customarily  associated with the
position of Chief  Executive  Officer and President;  (b)  Employee's  principal
place of  employment  is  relocated  beyond a 50-mile  radius  of the  Company's
principal business office on the date hereof;  (c) Employee's salary,  including
fringe benefits is materially  reduced;  or (d) the Company fails to maintain an
incentive bonus program  substantially  equivalent to the bonus program place on
the  date  hereof.  "Change  of  control"  shall  be  defined  as  a  merger  or
consolidation   which  results  in  the  shares  of  the  Company  held  by  the
stockholders  of  the  Company  immediately  prior  to  such  transaction  being
converted into less than 50% of the  outstanding  capital stock of the surviving
corporation,  the sale of  substantially  all of the assets of the  Company or a
transaction  or series of  related  transactions  in which  more than 50% of the
voting power of the Company is disposed of.



                                      E-3


         5. Non-Competition and Confidentiality.  Employee hereby represents and
acknowledges  that he has entered into, and is bound by the terms and conditions
of, the Company's standard Key Employee Non-Competition Agreement.

respect to such indebtedness whatsoever.

unenforceable in any respect,  such invalidity,  illegality or  unenforceability
shall not affect any other provision of this Agreement, but this Agreement shall
be construed as if such invalid,  illegal or unenforceable  provisions had never
been contained herein.

         9. Waivers and Modifications. This Agreement may not, in whole or part,
be waived, changed, amended, discharged or terminated orally or by any course of
dealing between the parties,  but only by an instrument in writing signed by the
parties  hereto.  No waiver by  either  party of any  breach by the other or any
provision  hereof  shall be deemed  to be a waiver of any later or other  breach
hereof or as a waiver of any other provisions of this Agreement.

sets forth the sole and entire  understanding  and agreement between the parties
as  to  its  subject  matter.  There  are  no  representations,   warranties  or
inducements  of any kind  relating to the  entering  into or the signing of this
Agreement that are not expressly set forth herein.

         11.  Assignment.  The  Employee  acknowledges  that the  services to be
rendered  by him are unique and  personal.  Accordingly,  the  Employee  may not
assign any of his rights or delegate any of his duties or obligations under this
Agreement or otherwise assign this Agreement.  The rights and obligations of the
Company under this Agreement shall inure to the benefit of, and shall be binding

                                                              July 20, 1996




Special Committee of the
  Board of Directors
Telebit Corporation
One Executive Drive
Chelmsford, MA  01824

  c/o William Schnoor, Esq.


To the Special Committee:

         You  have  requested  our  opinions,  as of  this  date,  as to (a) the
fairness, from a financial point of view, of the consideration to be received by
the holders of the outstanding  shares of Common Stock,  without par value, (the
"Common  Stock"),  of  Telebit  Corporation,   a  California   corporation  (the
"Company"),  and (b) the  fairness,  from a  financial  point  of  view,  of the
consideration  to be  received by the Company in  connection  with the  Proposed
Transactions referred to hereinafter.

         Pursuant to the  proposed  Agreement  and Plan of  Reorganization  (the
"Reorganization  Agreement"), to be entered into by and among the Company, Cisco
Systems, Inc., a California corporation,  (the "Purchaser"),  and a wholly-owned
subsidiary of the Purchaser (the "Sub"),  the Company will enter into a business
combination transaction effected by a cash-for-stock merger of the Sub, with and
into  the  Company,   with  the  Company   surviving  the  merger  (the  "Merger
Transaction");  as a condition to the Merger  Transaction a simultaneous sale of
the Company's  legacy  business to a newly formed  corporation  ("Newco")  whose
executive  officers  will be certain  members of the Company's  management  (the
"Asset Transaction" and, collectively with the Merger Transaction, the "Proposed
Transactions")  will be effected pursuant to a proposed Asset Purchase Agreement
(the "Asset  Purchase  Agreement") to be entered into by and between the Company
and Newco. Unless otherwise  specifically  defined herein, all capitalized terms
used herein shall have the meanings ascribed to such terms in the Reorganization
Agreement and the Asset Purchase Agreement.




[OSC]

         Pursuant to the terms, and subject to the conditions  contained in, the
Proposed Transactions, among other things, (i)each share of the Company's Common
Stock issued and  outstanding  on the date hereof and as of the  Effective  Time
will be  converted  into  the  right  to  receive  $13.35  in cash  and (ii) the
Company's  legacy  business  assets  (excluding  $3.5  million in cash) would be
acquired by Newco for an aggregate purchase price of $31.5 million, comprised of
a $31.5 million  Secured  Subordinated  Note due 2001. In addition,  the Company
will  purchase  $3.5  million of Class A  Redeemable  Preferred  Stock issued by
Newco.

         We understand that all approvals  required for the  consummation of the
Proposed  Transactions  have  been or,  prior to  consummation  of the  Proposed
Transactions,  will  be  obtained.  As you  know  Allen &  Company  Incorporated
("Allen") will receive a fee for preparing and rendering  this opinion  pursuant
to the engagement letter agreement by and between the Company and Allen.

         In arriving at our opinion, we have among other things:

         (i)      reviewed   the   terms   and   conditions   of  the   Proposed
                  Transactions,  including  the draft  Reorganization  Agreement
                  between  Purchaser  and the Company  and the draft  agreements
                  ancillary  thereto,  as  well  as  the  draft  Asset  Purchase
                  Agreement   between  Newco  and  the  Company  and  the  draft
                  agreements  ancillary  thereto  (none  of  which  prior to the
                  delivery of this opinion has been executed by the parties);

         (ii)     analyzed publicly available  historical business and financial
                  information  relating  to the Company  and the  Purchaser,  as
                  presented in documents  filed with the Securities and exchange
                  Commission;

         (iii)    reviewed  certain  business  plans,  budgetary, and other data
                  provided  to us by the  Company relating to its businesses;

         (iv)     conducted  discussions  with  certain  members  of the  senior
                  management  of the  Company  with  respect  to  the  financial
                  condition,  business,  operations,  strategic  objectives  and
                  prospects  of  the  Company,   as  well  as  industry   trends
                  prevailing in the Company's business;

         (v)      reviewed and analyzed public  information,  including  certain
                  stock  market  data  and  financial  information  relating  to
                  selected  public  companies  in  lines  of  business  which we
                  believe to be comparable to the Company's;



[OSC]

         (vi)     reviewed the trading  history of the  Company's Common  Stock,
                  including  its  performance  in  comparison to market indices
                  and to selected companies in comparable businesses;

         (vii)    reviewed public financial and transaction information relating
                  to business  combinations  we  deemed to be comparable to the
                  Proposed Transactions;

         (viii)   considered premiums paid in transactions we deemed comparable 
                  to the Merger Transaction;

         (ix)     analyzed  discounted cash flows of each of the Company and the
                  portion of the Company  that is the subject of the Asset
                  Transaction; and

         (x)      conducted such other financial  analyses and investigations as
                  we deemed  necessary  or  appropriate  for the purposes of the
                  opinion expressed herein.

         In rendering our opinion,  we have assumed and relied upon the accuracy
and completeness of the financial and other  information  respecting the Company
and the  Purchaser  and any other  information  provided  to us, and we have not
assumed any responsibility for any independent  verification of such information
or any  independent  valuation or appraisal of any of the assets of the Company.
With respect to the business plans referred to above,  we have assumed that they
have been reasonably prepared on a basis reflecting the best currently available
information  and the good faith estimates and judgments of the management of the
Company as to the future financial performance of the Company's business.

         In addition to our review and analysis of the specific  information set
forth above,  our opinion herein  reflects and gives effect to our assessment of
general economic,  monetary and market conditions existing as of the date hereof
as they may affect the business and prospects of the Company.

         In  connection  with the  Proposed  Transactions,  the scope of Allen's
engagement  has been  limited to the  preparation  and  rendering of the opinion
contained  herein.  In connection with the preparation of this opinion,  we have
not been  authorized  by the Company or its Board of Directors  to solicit,  nor
have we solicited,  third party  indications of interest for the  acquisition of
all or any part of the Company.  Furthermore,  the opinion  rendered herein does
not   constitute  a   recommendation   that  the  Company  pursue  the  Proposed
Transactions or that any stockholder of the Company vote to approve the Proposed
Transactions.




[OSC]

         Based on and subject to the foregoing,  we are of the opinions that, as
of this  date,  (a) the  consideration  to be  received  by the  holders  of the
Company's  Common  Stock  pursuant  to the  Merger  Transaction  is fair to such
holders from a financial point of view, and (b) the consideration to be received
by the Company  pursuant to the Asset  Transaction is fair to the Company from a
financial point of view.

                                                  Very truly yours,

                                                  ALLEN & COMPANY INCORPORATED

                                                  Managing Director





                                                                      APPENDIX E














         1300. REORGANIZATION OR SHORT-FORM MERGER, DISSENTING SHARES; CORPORATE
PURCHASE  AT  FAIR  MARKET  VALUE;  DEFINITIONS.  (a)  If  the  approval  of the
outstanding   shares   (Section  152)  of  a  corporation   is  required  for  a
reorganization  under  subdivisions  (a)  and (b) or  subdivision  (e) or (f) of
Section  1201,  each  shareholder  of the  corporation  entitled  to vote on the
transaction  and each  shareholder  of a subsidiary  corporation in a short-form
merger may, by complying with this chapter, require the corporation in which the
shareholder  holds  shares to purchase  for cash at their fair market  value the
shares  owned by the  shareholder  which are  dissenting  shares as  defined  in
subdivision  (b). The fair market value shall be determined as of the day before
the first announcement of the terms of the proposed reorganization or short-form
merger,  excluding  any  appreciation  or  depreciation  in  consequence  of the
proposed action, but adjusted for any stock split, reverse stock split, or share
dividend which becomes effective thereafter.

         (b) As used in this  chapter,  "dissenting  shares"  means shares which
come within all of the following descriptions:

                  (1) Which were not immediately prior to the  reorganization or
short-form  merger  either  (A)  listed  on  any  national  securities  exchange
certified by the Commissioner of Corporations  under  subdivision (o) of Section
25100 or (B)  listed  on the list of OTC  margin  stocks  issued by the Board of
Governors  of  the  Federal  Reserve  System,  and  the  notice  of  meeting  of
shareholders to act upon the reorganization summarizes this section and Sections
1301, 1302, 1303 and 1304; provided, however, that this provision does not apply
to any shares with  respect to which there  exists any  restriction  on transfer
imposed 


                                        1


by the corporation or by any law or regulation;  and provided,  further,
that  this  provision  does  not  apply  to any  class of  shares  described  in
subparagraph  (A) or (B) if demands  for  payments  are filed with  respect to 5
percent or more of the outstanding shares of that class.

                  (2) Which were  outstanding on the date for the  determination
of shareholders entitled to vote on the reorganization and (A) were not voted in
favor of the  reorganization  or, (B) if described in subparagraph (A) or (B) of
paragraph (1) (without regard to the provisions in that  paragraph),  were voted
against the  reorganization,  or which were held of record on the effective date
of a short-form  merger;  provided,  however,  that subparagraph (A) rather than
subparagraph  (B) of this  paragraph  applies  in any case  where  the  approval
required by Section 1201 is sought by written consent rather than at a meeting.

                  (3) Which the  dissenting  shareholder  has demanded  that the
corporation  purchase at their fair market  value,  in  accordance  with Section
1301.

                  (4)  Which  the  dissenting   shareholder  has  submitted  for
endorsement, in accordance with Section 1302.

         (c) As used in this chapter,  "dissenting shareholder" means the record
holder of dissenting shares and includes a transferee of record.

         1301. NOTICE OF HOLDERS OF DISSENTING SHARES IN REORGANIZATIONS; DEMAND
FOR  PURCHASE;  TIME;  CONTENTS.  (a) If, in the case of a  reorganization,  any
shareholders  of a  corporation  have a right  under  Section  1300,  subject to
compliance with  paragraphs (3) and (4) of subdivision  (b) thereof,  to require
the corporation to purchase their shares for


                                       2


cash,  such  corporation  shall  mail to each such  shareholder  a notice of the
approval of the reorganization by its outstanding shares (Section 152) within 10
days after the date of such  approval,  accompanied  by a copy of Sections 1300,
1302,  1303, 1304 and this section,  a statement of the price  determined by the
corporation to represent the fair market value of the dissenting  shares,  and a
brief description of the procedure to be followed if the shareholder  desires to
exercise the  shareholder's  right under such  sections.  The statement of price
constitutes  an offer by the  corporation  to purchase  at the price  stated any
dissenting  shares as defined in  subdivision  (b) of Section 1300,  unless they
lose their status as dissenting shares under Section 1309.

         (b) Any  shareholder  who has a right to  require  the  corporation  to
purchase  the  shareholder's  shares for cash  under  Section  1300,  subject to
compliance  with  paragraphs  (3) and (4) of  subdivision  (b) thereof,  and who
desires the  corporation  to purchase such shares shall make written demand upon
the  corporation  for the purchase of such shares and payment to the shareholder
in cash of their fair market value.  The demand is not effective for any purpose
unless it is received by the  corporation  or any transfer  agent thereof (1) in
the  case  of  shares  described  in  clause  (i) or (ii)  of  paragraph  (1) of
subdivision  (b) of  Section  1300  (without  regard  to the  provisos  in  that
paragraph),  not later than the date of the  shareholders'  meeting to vote upon
the  reorganization,  or (2) in any other case  within 30 days after the date on
which  the  notice  of  the  approval  by the  outstanding  shares  pursuant  to
subdivision  (a) or the notice  pursuant to subdivision  (i) of Section 1110 was
mailed to the shareholder.

                                       3


         (c) The demand  shall  state the number and class of the shares held of
record by the  shareholder  which the  shareholder  demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the  announcement  of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.
 
         1302.  SUBMISSION OF SHARE  CERTIFICATES FOR  ENDORSEMENT;  UNCERTIFIED
SECURITIES. Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the  shareholder,  the shareholder  shall submit to the corporation at
its principal office or at the office of any transfer agent thereof,  (a) if the
shares are certificated securities,  the shareholder's certificates representing
any shares which the shareholder  demands that the corporation  purchase,  to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertified securities, written notice of the number of
shares  which  the  shareholder  demands  that the  corporation  purchase.  Upon
subsequent  transfers of the dissenting  shares on the books of the corporation,
the  new  certificates,   initial  transaction  statement,   and  other  written
statements  issued therefor shall bear a like statement,  together with the name
of the original dissenting holder of the shares.

         1303.  PAYMENT OF AGREED  PRICE WITH  INTEREST;  AGREEMENT  FIXING FAIR
MARKET  VALUE;  FILING;  TIME  OF  payment.  (a)  If  the  corporation  and  the
shareholder agree that the 


                                       4

shares  are  dissenting  shares  and  agree  upon the price of the  shares,  the
dissenting  shareholder is entitled to the agreed price with interest thereon at
the legal  rate on  judgments  from the date of the  agreement.  Any  agreements
fixing the fair market value of any dissenting shares as between the corporation
and the holders thereof shall be filed with the secretary of the corporation.

         (b)  Subject to the  provisions  of Section  1306,  payment of the fair
market value of dissenting  shares shall be made within 30 days after the amount
thereof has been  agreed or within 30 days after any  statutory  or  contractual
conditions to the reorganization  are satisfied,  whichever is later, and in the
case of  certificated  securities,  subject  to  surrender  of the  certificates
therefor, unless provided otherwise by agreement.

         1304.  ACTION TO DETERMINE WHETHER SHARES ARE DISSENTING SHARES OR FAIR
MARKET  VALUE;  LIMITATION;  JOINDER;  CONSOLIDATION;  DETERMINATION  OF ISSUES;
APPOINTMENT OF  APPRAISERS.  (a) If the  corporation  denies that the shares are
dissenting  shares or the corporation and the shareholder fail to agree upon the
fair market value of the shares, then the shareholder demanding purchase of such
shares as dissenting  shares or any  interested  corporation,  within six months
after  the  date on which  notice  of the  approval  by the  outstanding  shares
(Section 152) or notice  pursuant to subdivision  (i) of Section 1110 was mailed
to the  shareholder,  but not  thereafter,  may file a complaint in the superior
court of the proper county praying the court to determine whether the shares are
dissenting  shares or the fair market value of the dissenting  shares or both or
may intervene in any action pending on such a complaint.


                                       5

         (b) Two or more  dissenting  shareholders  may join as plaintiffs or be
joined as  defendants  in any such  action and two or more such  actions  may be
consolidated.

         (c) On the trial of the action,  the court shall  determine the issues.
If the status of the shares as  dissenting  shares is in issue,  the court shall
first determine that issue. If the fair market value of the dissenting shares is
in issue,  the court shall  determine,  or shall  appoint one or more  impartial
appraisers to determine, the fair market value of the shares.

         1305.  REPORT  OF  APPRAISERS;  CONFIRMATION;  DETERMINATION  BY COURT;
JUDGMENT;  PAYMENT;  APPEAL;  COSTS.  (a) If the court  appoints an appraiser or
appraisers,  they shall proceed forthwith to determine the fair market value per
share.  Within the time fixed by the court,  the  appraisers,  or a majority  of
them,  shall  make and file a report in the  office  of the clerk of the  court.
Thereupon on the motion of any party, the report shall be submitted to the court
and considered on such evidence as the court  considers  relevant.  If the court
finds the report reasonable, the court may confirm it.

         (b) If a majority of the  appraisers  appointed fail to make and file a
report within 10 days from the date of their  appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

         (c)  Subject to the  provisions  of  Section  1306,  judgment  shall be
rendered  against the  corporation  for  payment of an amount  equal to the fair
market value of each  dissenting  share  multiplied  by the number of dissenting
shares which any dissenting  shareholder  who is a party, or who has intervened,
is entitled to require the corporation to purchase, with interest thereon at the
legal rate from the date on which judgment was entered.


                                       6


         (d) Any such  judgment  shall be  payable  forthwith  with  respect  to
uncertificated securities and with respect to certificated securities, only upon
the  endorsement  and delivery to the  corporation of the  certificates  for the
shares described in the judgment. Any party may appeal from the judgment.

         (e) The costs of this action,  including reasonable compensation to the
appraisers  to be fixed by the court,  shall be assessed or  apportioned  as the
court considers  equitable,  but, if the appraisal  exceeds the price offered by
the  corporation,  the  corporation  shall  pay  the  costs  (including  in  the
discretion of the court  attorneys'  fees, fees of expert witnesses and interest
at the legal rate on judgments  from the date of compliance  with Sections 1300,
1301 and 1302 if the value  awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

         1306. PREVENTION OF IMMEDIATE PAYMENT;  STATUS AS CREDITORS;  INTEREST.
To the  extent  that the  provisions  of  Chapter 5 prevent  the  payment to any
holders of  dissenting  shares of their fair  market  value,  they shall  become
creditors of the  corporation  for the amount thereof  together with interest at
the legal rate on judgments  until the date of payment,  but  subordinate to all
other  creditors  in any  liquidation  proceeding,  such debt to be payable when
permissible under the provisions of Chapter 5.

         1307.  DIVIDENDS ON DISSENTING SHARES. Cash dividends declared and paid
by the corporation upon the dissenting  shares after the date of approval of the
reorganization by the outstanding  shares (Section 152) and prior to payment for
the shares by the corporation  shall be credited  against the total amount to be
paid by the corporation therefor.


                                       7


         1308. RIGHTS OF DISSENTING  SHAREHOLDERS PENDING VALUATION;  WITHDRAWAL
OF DEMAND FOR PAYMENT.  Except as expressly limited in this chapter,  holders of
dissenting  shares  continue to have all the rights and  privileges  incident to
their  shares,  until the fair  market  value of their  shares is agreed upon or
determined.  A  dissenting  shareholder  may not  withdraw a demand for  payment
unless the corporation consents thereto.

         1309.   TERMINATION  OF  DISSENTING   SHARE  AND  SHAREHOLDER   STATUS.
Dissenting shares lose their status as dissenting shares and the holders thereof
cease to be  dissenting  shareholders  and cease to be  entitled  to require the
corporation to purchase their shares upon the happening of any of the following:

         (a) The corporation  abandons the  reorganization.  Upon abandonment of
the  reorganization,  the  corporation  shall pay on  demand  to any  dissenting
shareholder  who has initiated  proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.

         (b)  The  shares  are  transferred   prior  to  their   submission  for
endorsement in accordance  with Section 1302 or are  surrendered  for conversion
into shares of another class in accordance with the articles.

         (c) The dissenting  shareholder  and the  corporation do not agree upon
the status of the shares as dissenting  shares or upon the purchase price of the
shares,  and neither  files a complaint  or  intervenes  in a pending  action as
provided in Section  1304,  within six months  after the date on which notice of
the approval by the outstanding  shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.


                                       8


         (d) The dissenting  shareholder,  with the consent of the  corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.
 
        1310.  SUSPENSION OF RIGHT TO  COMPENSATION  OR VALUATION  PROCEEDINGS;
LITIGATION OF  SHAREHOLDERS'  approval.  If litigation is instituted to test the
sufficiency  or regularity  of the votes of the  shareholders  in  authorizing a
reorganization,  any proceedings  under Section 1304 and 1305 shall be suspended
until final determination of such litigation.

         1311. EXEMPT SHARES. This chapter,  except Section 1312, does not apply
to classes  of shares  whose  terms and  provisions  specifically  set forth the
amount to be paid in respect to such shares in the event of a reorganization  or
merger.

         1312. RIGHT OF DISSENTING  SHAREHOLDER TO ATTACH,  SET ASIDE OR RESCIND
MERGER OR REORGANIZATION;  RESTRAINING ORDER OR INJUNCTION;  CONDITIONS.  (a) No
shareholder  of a  corporation  who has a right  under  this  chapter  to demand
payment of cash for the shares held by the  shareholder  shall have any right at
law or in equity to attack the  validity  of the  reorganization  or  short-form
merger,  or to have  the  reorganization  or  short-form  merger  set  aside  or
rescinded,  except in an action to test whether the number of shares required to
authorize  or  approve  the  reorganization  have  been  legally  voted in favor
thereof;  but any  holder  of  shares  of a class  whose  terms  and  provisions
specifically  set forth the amount to be paid in respect to them in the event of
a reorganization  or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the  reorganization are
approved  pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.


                                       9


         (b) If one of the parties to a reorganization  or short-form  merger is
directly  controlled  by, or under common  control  with,  another  party to the
reorganization  or  short-form  merger,  subdivision  (a) shall not apply to any
shareholder  of such  party  who has  not  demanded  payment  of cash  for  such
shareholder's shares pursuant to this chapter; but if the shareholder institutes
any action to attack the validity of the  reorganization or short-form merger or
to have the  reorganization  or short-form  merger set aside or  rescinded,  the
shareholder  shall not  thereafter  have any right to demand payment of cash for
the  shareholder's  shares  pursuant  to this  chapter.  The court in any action
attacking the validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded shall not restrain or
enjoin the consummation of the transaction  except upon 10 days' prior notice to
the  corporation  and upon a  determination  by the court that  clearly no other
remedy will  adequately  protect  the  complaining  shareholder  or the class of
shareholders of which such shareholder is a member.
 
         (c) If one of the parties to a reorganization  or short-form  merger is
directly or indirectly  controlled  by, or under common  control  with,  another
party to the  reorganization  or short-form  merger, in any action to attack the
validity  of  the   reorganization   or   short-form   merger  or  to  have  the
reorganization  or short-form  merger set aside or  rescinded,  (1) a party to a
reorganization  or  short-form  merger  which  controls  another  party  to  the
reorganization  or  short-form  merger shall have the burden of proving that the
transaction  is jut and  reasonable  as to the  shareholders  of the  controlled
party,  and (2) a person who controls  two or more  parties to a  reorganization
shall have the burden of

                                       10


proving that the  transaction is just and reasonable as to the  shareholders  of
any party so controlled.
